Objective To collect the data of nosocomial infection surveillance in secondary and tertiary medical institutions in Jiangsu Province and conduct comparative analysis among different regions to find out the gaps and provide basis for targeted continuous improvement. MethodsCombined with the requirements of grade hospital evaluation and high-quality development of public hospitals, the data of nosocomial infection incidence in medical institutions of Jiangsu Province in the first quarter of 2023 were collected by autonomous reporting and information capture, and the province was divided into three regions according to location: South Jiangsu, Central Jiangsu and North Jiangsu for analysis, so as to evaluate the regional level. Results A total of 109 medical institutions were included, including 78 tertiary hospitals and 31 secondary hospitals. The overall incidence rate of nosocomial infection was 0.81% (0.90%). The incidence of central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP) and catheter-associated urinarytract infection (CAUTI) were 0.113‰, 1.553‰ and 0.424‰, respectively. The proportion of prophylactic drugs in Class Ⅰ incision and the incidence of surgical site infection in Class Ⅰ incision were 17.72% and 0.16%, respectively. In the above infection indicators, the incidences of CLABSI and VAP were higher in Central Jiangsu, while the other indicators were higher in South Jiangsu than in Central Jiangsu than in North Jiangsu. The utilization rate of antibiotics and the detection rate of pathogens in inpatients were 41.07% and 41.50%, respectively. Among South, North, and Central Jiangsu, the utilization rate of antibiotics was 41.83%, 41.51%, and 39.51%, respectively (χ2=446.789, P<0.001), and the detection rate of pathogens was 46.09%, 40.94%, and 35.09%, respectively (χ2=3036.865, P<0.001). In the detection rate of drug-resistant bacteria infection, the top 3 were carbapenem-resistant Acinetobacter baumannii (0.067%), carbapenem-resistant Klebsiella pneumoniae (0.031%) and methicillin-resistant Staphylococcus aureus (0.029%). Among them, the infection rate of drug-resistant bacteria in South Jiangsu was significantly higher than that in the other two regions. The detection rates of carbapenem-resistant Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus were close to each other (83.77% vs. 53.91%), while the detection rates of carbapenem-resistant Escherichia coli (χ2=95.619, P<0.001), carbapenem-resistant Klebsiella pneumoniae (χ2=520.855, P<0.001) and carbapenem-resistant Pseudomonas aeruginosa (χ2=191.918, P<0.001) in South Jiangsu were significantly higher than those in Central and North Jiangsu. Conclusions There are significant differences in nosocomial infection surveillance data of medical institutions in different regions of Jiangsu Province. It is emphasized that targeted quality control feedback, supervision and rectification should be carried out while hospital infection monitoring.
Objective To explore the application of regional citrate anticoagulation (RCA) in continuous renal replacement therapy (CRRT) for patients with sepsis and hyperlactacidemia, and to provide a basis for the clinical application of RCA in such patients. Methods Sepsis patients who underwent RCA-CRRT at West China Hospital of Sichuan University between May 2021 and May 2023 were retrospectively included. Patients were divided into a normal lactate group (≤2.0 mmol/L) and a hyperlactacidemia group (>2.0 mmol/L) based on their initial lactate levels before CRRT, and subgroup analysis was performed on patients with moderate hyperlactacidemia (2 mmol/L<lactate level<4 mmol/L) and severe hyperlactacidemia (≥4.0 mmol/L). Propensity score matching (PSM) was used, and baseline characteristics and outcome measures of different groups of patients were compared. Results A total of 441 patients were included, with 228 in the normal lactate group and 213 in the hyperlactacidemia group. Before PSM, there were statistically significant differences in the proportion of liver failure, proportion of chronic kidney disease, mean arterial pressure, bicarbonate, total bilirubin, creatinine, activated partial thromboplastin time, international standardized ratio, procalcitonin, and interleukin-6 between the normal lactate group and the hyperlactacidemia group (P<0.05). After PSM, there were 162 patients in both the normal lactate group and the hyperlactacidemia group. There was no statistically significant difference in baseline characteristics between the two groups of patients (P>0.05). The incidence of citric acid accumulation in the normal lactate group and the hyperlactacidemia group was 13.0% and 25.9%, respectively (P<0.05). There was no statistically significant difference in the incidence of metabolic acidosis, metabolic alkalosis, hypernatremia, filter coagulation events, or in-hospital mortality between the two groups (P>0.05). Kaplan-Meier survival analysis showed that there was no statistically significant difference in the first extracorporeal circulation lifespan between the normal lactate group and the hyperlactacidemia group (P>0.05). Among 213 patients with hyperlactacidemia, 186 had moderate hyperlactacidemia and 27 had severe hyperlactacidemia. Before PSM, there were statistically significant differences in the proportion of male, proportion of diabetes, albumin level, international standardized ratio, and interleukin-6 between moderate and severe hyperlactacidemia groups (P<0.05). After PSM, there were 22 patients in both the moderate and severe hyperlactacidemia groups. There was no statistically significant difference in baseline characteristics between the two groups of patients (P>0.05). The incidence of citric acid accumulation was 18.2% and 50.0% in the moderate and severe hyperlactacidemia groups, respectively (P<0.05). There was no statistically significant difference in the incidence of metabolic acidosis, metabolic alkalosis, hypernatremia, filter coagulation events, or in-hospital mortality between the two groups (P>0.05). Kaplan-Meier survival analysis showed that there was no statistically significant difference in the first extracorporeal circulation lifespan between the moderate and severe hyperlactacidemia groups (P>0.05). Conclusion When RCA is used for CRRT anticoagulation in patients with sepsis and hyperlactacidemia, the incidence of citric acid accumulation is high (especially in patients with severe hyperlactacidemia), and should be closely monitored.
ObjectiveTo investigate the prognosis after breast conserving surgery (BCS) and modified radical mastectomy (MRM) in patients with stage Ⅰ–Ⅱ breast cancer, and analyze the factors related to locoregional recurrence (LRR).MethodsThe clinicopathologic and prognostic data of patients with stage Ⅰ–Ⅱ breast cancer who underwent the surgical treatment in the First Affiliated Hospital of Chongqing Medical University from January 2011 to December 2014 were analyzed. The clinicopathologic characteristics and prognostic differences of the BCS group and MRM group were compared. The factors related to LRR of patients underwent the BCS and MRM were analyzed.ResultsA total of 1 330 patients with stage Ⅰ–Ⅱ breast cancer were included in this study, including 230 in the BCS group and 1 100 in the MRM group. Compared with the MRM group, the patients in the BCS group had higher height (P<0.001), younger age (P<0.001), smaller tumor diameter (P<0.001), and less axillary lymph node metastasis (P<0.001). Up to August 2019, 149 cases (18 cases in the BCS group and 131 cases in the MRM group) were lost, with a follow-up rate of 88.8%. The median follow-up time was 71 months (4－103 months). The LRR rate of the BCS group was higher than that of the MRM group (6.1% versus 2.5%, χ2=7.002, P<0.01). The locoregional recurrence-free survival of the MRM group was better than that of the BCS group (χ2=7.886, P<0.01). However, there were no statistical differences between the two groups in terms of the distant metastasis-free survival and disease-free survival (P>0.05). In the patients underwent the BCS, the HER-2 was associated with the LRR (P<0.05), and the axillary lymph node metastasis was associated with the LRR in the patients underwent the MRM (P<0.05).ConclusionsAccording to results of this study, although there is a significant difference in locoregional recurrence-free survival between BCS group and MRM group in patients with stage Ⅰ–Ⅱ breast cancer, there are no statistical differences in distant metastasis-free survival and disease-free survival between the two groups. Therefore, it is safe and feasible for choosing appropriate patients with stage Ⅰ–Ⅱ breast cancer to underwent breast-conserving treatment.
ObjectiveTo observe the curative effect, survival rate, enucleation rate and pathological characteristics of retinoblastoma (RB) in children.MethodsRetrospective clinical study. From March 1999 to December 2018, a total of 313 patients (445 eyes) with RB diagnosed in Ophthalmology Department of Peking University People’s Hospital were enrolled in the study. Among them, 175 were male (55.9%), 138 were female (44.1%); 181 were monocular and 132 were binocular. The international standard of intraocular RB staging (IIRC) was 6, 13, 6, 52, 227 and 9 patients of A, B, C, D, E and extraocular stages respectively. Among the 313 patients, 245 patients were confirmed to the survivance, of which 22 cases (9.0%, 22/245) died. Among 445 eyes, 330 eyes definitely whether or not were enucleated; 184 eyes had definite IIRC stage, eye examination results, definite treatment plan and times before enucleation and definite pathological tumor node metastasis stage after operation. The basic information, demographic characteristics, clinical information, enucleation and treatment plan, pathological and immunohistochemical results were recorded. Binary logistic regression was used to analyze the risk factors of high risk pathological features (HRF) and prognosis in patients with RB.ResultsFrom 1999 to 2018, the survival rate of 245 patients was increased from 82.6% to 96.3% year by year; the enucleation rate of 330 eyes with final enucleation was reduced from 68.8% to 58.3% year by year. The rate of enucleation in stage D and stage E decreased from 83.3% and 100% before 2005 to 37.5% and 85.4% after 2014, respectively. Monocular disease (β=－1.551, P=0.005), stage D, stage E and extraocular stage in IIRC stage (P＜0.005) were the independent risk factors of RB enucleation, while the protective factors were Interventional chemotherapy of ophthalmic artery (IAC) (β=－0.877, P＜0.001). HRF was found in 51 eyes (27.7%). Age of onset (β=0.019, P=0.016) and glaucoma (β=0.816, P=0.050) were independent risk factors for HRF in RB pathology, while IAC treatment was the protective factor for enucleation (β=21.432, P＜0.001).ConclusionsAfter comprehensive treatment, the general trend of RB enucleation rate is gradually decreasing. IAC treatment can reduce the enucleation rate of stage D and E. The older age of onset and glaucoma stage are the independent risk factors of HRF, and IAC can reduce the risk factors of HRF.
ObjectiveTo investigate the effectiveness of cervical pedicle screw implantation technique under regional method.MethodsThe clinical data of 85 patients who met the selection criteria between April 2010 and May 2018 were retrospectively analyzed. There were 57 males and 28 females, aged 35-68 years, with an average of 57.6 years. Among them, there were 10 cases of ossification of posterior longitudinal ligament, 68 cases of cervical spondylosis with multilevel stenosis, 3 cases of cervical tumor, 1 case of congenital malformation, and 3 cases of cervical trauma; the lower cervical spine lesions involved C3-C7. Preoperative Frankel spinal cord injury grading: 2 cases of grade C, 51 cases of grade D, and 32 cases of grade E. Cervical pedicle screw implantation technique under regional method was performed with a total of 618 pedicle screws. Postoperative changes in neurological symptoms were observed; cervical mouth opening anteroposterior and lateral X-ray films and cervical CT examinations were performed to evaluate the pedicle screws position.ResultsThe operation time was 2.5-4.0 hours, with an average of 3.0 hours. The intraoperative blood loss was 180-550 mL, with an average of 345 mL. No intraoperative vascular or nerve injury occurred. The patients with neurological symptoms were relieved to varying degrees. There were 2 cases of superficial incision infection after operation, the wound healed after enhanced dressing change. The postoperative hospital stay was 5-14 days, with an average of 8.4 days. At discharge, Frankel neurological grading was grade D in 26 patients and grade E in 59 patients. All the patients were followed up 6-24 months, with an average of 13 months. At last follow-up, cervical X-ray films showed the good pedicle screw fixation without loosening. Cervical CT evaluated the position of pedicle screws: 523 pedicle screws (84.7%) in grade Ⅰ, 80 (12.9%) in grade Ⅱ, and 15 (2.4%) in grade Ⅲ; the accuracy rate of the screw position was 97.6%.ConclusionCervical pedicle screw implantation technique under regional method can significantly improve the success rate of screw implantation. It is easy to operate, does not destroy the bone cortex, and has stable fixation.
The aim of this paper is to reveal the change of the brain function for nicotine addicts after smoking cessation, and explore the basis of neural physiology for the nicotine addicts in the process of smoking cessation. Fourteen subjects, who have a strong dependence on nicotine, have agreed to give up smoking and insist on completing the test, and 11 volunteers were recruited as the controls. The resting state functional magnetic resonance imaging and the regional homogeneity (ReHo) algorithm have been used to study the neural activity before and after smoking cessation. A two factors mixed design was used to investigate within-group effects and between-group effects. After 2 weeks’ smoking cessation, the increased ReHo value were exhibited in the brain area of supplementary motor area, paracentral lobule, calcarine, cuneus and lingual gyrus. It suggested that the synchronization of neural activity was enhanced in these brain areas. And between-group interaction effects were appeared in supplementary motor area, paracentral lobule, precentral gyrus, postcentral gyrus, and superior frontal gyrus. The results indicate that the brain function in supplementary motor area of smoking addicts would be enhanced significantly after 2 weeks’ smoking cessation.
ObjectiveTo summarize the common imaging features of liver cancer after local-regional therapy in order to more accurately evaluate the post-treatment response of it. MethodThe literatures of studies on imaging features after ablation, transcatheter therapy, and radiotherapy of liver cancer in recent years were searched and reviewed. ResultsIt was not accurate to evaluate the response of liver cancer after treatment only by comparing the size of tumor before and after treatment. We should follow up and observe the changes of enhancement components after tumor treatment, and pay attention to identify the normal features after treatment. ConclusionsImaging evaluation after local-regional therapy of liver cancer is of great significance in management and clinical decision-making of patients with liver cancer. Standard response evaluation systems such as EASL or mRECIST should be carefully applied after local-regional therapy of liver cancer. Treatment response of patients should be comprehensively evaluated in combination with the characteristics of local-regional therapy methods and timing, so as to avoid delaying timing of secondary treatment and causing excessive treatment.
ObjectiveTo investigate the current situation of orthopedic quality control and management in county-level regional general hospitals in Guangdong, and to provide a scientific basis for further standardizing the procedures of orthopedic quality control and management in county-level regional general hospitals and continuously improving the work of provincial orthopedic quality control center.MethodsFrom June 2019 to July 2020, online and offline questionnaire survey and field survey were used to investigate the quality control and management of orthopedic departments in 22 county-level regional general hospitals in Guangdong.ResultsAmong the overall scores of the surveyed hospitals, the highest score was 96.5, the lowest score was 72.0. There were 6 hospitals with a total score of “excellent” (accounting for 27.3%). The “facilities and equipment” and “medical quality” of the surveyed hospitals were relatively valued. Taking Guangzhou, the capital of Guangdong as the center, the districts and counties were divided into the east, the south, the west and the north regions, and the difference in overall scores of orthopedics among the four regions was statistically significant (F=6.299, P=0.004). The unqualified rates of department setting, key technology development, average hospitalization days of representative diseases, equipment allocation, personnel allocation, department management and building layout were relatively high, which were 77.3%, 63.6%, 45.5%, 40.9%, 40.9%, 36.4% and 36.4%, respectively. Most hospitals had set up special debridement rooms in orthopedic department (95.5%), and the management and monitoring of the use of antibacterial drugs was mostly reasonable (90.9%). In terms of the level of orthopedic medical treatment, only 3 hospitals with sufficient key technologies reached the standard, accounting for 13.6%, and only 7 hospitals reached the standard of scientific research capacity, accounting for 31.8%. In terms of quality control, the numbers of hospitals with qualified medical record sampling (72.7%), perfect management and supervision mechanism (86.4%) and quality management team in departments (77.3%) were the least. In addition, among the investigated hospitals, beds were in short supply in orthopedic departments, with 12 hospitals accounting for 54.5% being deducted; 16 hospitals (72.7%) were deducted for unqualified doctor-patient ratio and 11 hospitals (50.0%) were deducted for unqualified nurse-patient ratio.ConclusionsThe overall level of orthopedics construction and management in the surveyed hospitals is uneven. The medical professional and technical level is insufficient. It is difficult to meet the practical needs, and there is an imbalance in the ratio of medical personnel. In the future, it is necessary to strengthen the quality control of orthopedic medical care, strengthen the medical technology training of county-level regional general hospitals and increase the medical and health resources and capital investment, so as to improve the quality control of county-level regional general hospitals.
ObjectiveTo research the influence of anticoagulation to blood clotting function in patients who experienced cardiopulmonary bypass surgery under continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA), low molecular weight heparin (LMWH) anticoagulation and non-anticoagulation.MethodsWe retrospectively analyzed the clinical data of 146 patients who underwent CRRT after cardiopulmonary bypass surgery between January 2014 and December 2016. There were 98 males and 48 females at age of 60.51±14.29 years. All CRRT patients were allocated into three groups including a RCA group, a LMWH group, and a non-anticoagulation group, which were compared in terms of convention coagulation tests, platelet counts, thromboelastography, circuit lifespan and transfusion.ResultsThree hundred and fifty four CRRT patients were selected from patients above, including 152 patients in the LMWH group, 160 in the RCA group, and 42 in the non-anticoagulation group. The difference of CRRT circuits time among three groups was statistically different (P=0.023). And multiple comparison showed that the circuit lifespan of the RCA group was significantly longer than that of the non-anticoagulation group (34.50 h ranged 14.00 h to 86.00 h vs.15.00 h ranged 12.00 h to 50.88 h, P=0.033). One hundred and fifty-five CRRT patients last beyond 24 hours with same anticoagulation were selected, the results of coagulation tests, and the difference between CRRT starting and after 24 hours were compared. The difference of Angle and maximum amplitude(MA) of pre- and post-CRRT were significantly different among three groups by one-way ANOVA (P=0.004, 0.000), as well as between the RCA group and the LMWH group by multiple comparison (P=0.004, 0.000). There was no statistical difference in frequencies and doses of the transfusion of fresh frozen plasma and platelet among three groups.ConclusionRCA is an effective anticoagulation which may prolong circuit lifespan and has small impact on the coagulation function of patients who undergo CRRT after cardiopulmonary bypass surgery.
Objective To analyze the efficacy and safety of Intra-arterial chemotherapy (IAC) as secondly treatment in children with retinoblastoma (RB). Methods 42 eyes of 34 consecutive RB patients were enrolled in the study after intravenous chemotherapy (IVC), including 26 males and 8 females. The average age is 14.1 months. 21 cases were bilateral and 7 cases were unilateral. A total of 42 eyes of 34 patients were classified according to the International Intraocular Retinoblastoma Classification（IIRC）as group B(n=1, 2.4%), group C (n=3, 7.1%), group D (n=32, 76.2%), or group E (n=6, 14.3%). Tumor recurrence and tumor enlargement after IVC were 4 and 10 eyes respectively, accounting for 9.0% and 24.0% respectively. Sequential treatment after IVC followed by IAC were 28 eyes, accounting for 67.0%. All treatment eyes received IAC combined with laser, cryotherapy and other eye local treatment. The IAC regimen adopted the combination and alternation administration mode, by the combination of melphalan and carboplatin or the combination of melphalan and topotecan. According to the tumor changes after IAC decide whether IAC again. If tumors increased, vitreous or subretinal implants increased will be termination of IAC and enucleation. The mean follow-up time was (21.4±3.7) months after the last IAC treatment and (6.2±2.9) months after enucleation. Ocular preservation rate and complication were evaluated. Results The average IAC procedures performed on 42 eyes were (4.0±0.9). An overall ocular preservation rate of 76.2% was observed during follow-up periods due to calcification or inactivation of tumors (32 eyes), including group B (n=1, 100%), group C (n=1, 33.3%), group D (n=27, 84.4%), group E (n=3, 50%). 10 eyes were enucleated. Among them, 2 eyes of the tumor did not shrink after IAC, tumor recurrence (n=3), vitreous hemorrhage (n=3), enophthalmos (n=1), vitreous disseminated (n=1). 34 cases of children, transient eyelid oedema were 18 cases, vitreous hemorrhage and bone marrow suppression (Ⅰ-Ⅳ) were 1, 22 casese respectively. Conclusions IAC as secondly treatment is safe and effective for RB patients, however, there is still tumor recurrence. No serious ocular local and systemic complications were observed.
