A new fixator for spine was designed to restore the stability of spine in improving the treatment of thoraco-lumbar dislocation. This instrument was composed of six nails, two longitudinal connecting rods and two transverse connecting rods. On the surface of the nails, there were furrows engraved, instead of screw thread. It fixed the spine through pedicle of vertebra from the posterior approach. The fixed vertebrae were limited between two vertebrae. From 1989 th 1995, twelve patients with fracture-dislocation of thoraco-lumbar spine were reduced with this instrument. After four years follow-up, it showed that the deformity was corrected and the spine firmly fixed. Compared with Dick’s screws, it had the following advantages such as simple manipulation, increased strergth of nails and minimal damage to tissue during operation.
ObjectiveTo systematically review the efficacy of preoperative corticosteroids use as an adjunctive treatment for rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD). MethodsA evidence-based medicine study. The National Library of Medicine's PubMed, Web of Science, CNKI, and WanFang database were searched. Clinical controlled studies were selected the study object was RRDCD patients and the interventions were preoperative corticosteroids used as an adjunctive treatment. The search was conducted from January 2000 to January 2022. Duplicated, incomplete, or irrelevant articles were excluded. The conventional meta-analysis was used to evaluate the efficacy of corticosteroids used before surgery. The network meta-analysis was used to directly or indirectly compare the efficacy of oral corticosteroids or intravenous dexamethasone, peribulbar injection of glucocorticoids, prednisolone acetate eye-drops, intravitreal injection of triamcinolone acetonide (TA) and posterior sub-tenon injection of triamcinolone acetonide. Publication bias was evaluated by funnel plot. ResultsAccording to the search strategy, 43 articles were initially retrieved, and 929 eyes of 13 articles were finally included for analysis; 6 and 10 articles were included in the traditional meta-analysis and the network meta-analysis. Among the 6 studies included in the conventional meta-analysis, 5 studies were retrospective and 1 study was a randomized controlled trial, involving a total of 575 eyes. The analysis results showed that there was no significant difference in the primary retinal reattachment rate between the corticosteroids group and the control group [odds ratio (OR)= 1.53, 95% confidence interval (CI) 0.67-3.53, P=0.314]. Among the 10 studies included in the network meta-analysis, 7 studies were retrospective trials, 2 studies were randomized controlled trials, and 1 study was prospective trial, involving a total of 575 eyes. The analysis results showed that there were significant differences in the primary retinal reattachment rate between the triamcinolone acetonide intravitreal injection group and the no corticosteroid treatment group (OR=4.09, 95%CI 1.06-15.79). Sub-tenon injection triamcinolone acetonide had a higher incidence rate of ocular hypertension than oral glucocorticoid or intravenous dexamethasone (OR= 4.47, 95%CI 1.42-14.13). ConclusionsTriamcinolone acetonide intravitreal injection before surgery can improve the primary retinal reattachment rate in RRDCD patients. Patients with the posterior sub-tenon injection of triamcinolone acetonide should be alert to elevated intraocular pressure.
Objective To estimate the cost of continuous renal replacement therapy (CRRT) in public hospitals and analyze the main influencing factors of the cost, in order to provide evidence for the optimal application of CRRT technology. Methods In March 2021, activity-based costing was used to estimate and analyze the cost of CRRT, the data of which were collected from 5 hospitals in Jiangsu, Zhejiang, Henan, Sichuan and Xinjiang, and single factor sensitivity analysis was used to find the main influencing factors of the cost. Results The hourly treatment costs of CRRT in the 5 hospitals ranged from 265.30 to 474.44 yuan, with an average of 376.81 yuan. The costs of manpower and filters accounted for the top two largest proportions, the manpower cost of continuous veno-venous hemofiltration and continuous veno-venous hemodiafiltration accounted for 22.90% and 21.51%, respectively, and the filters cost of the two types of CRRT accounted for 15.07% and 17.73%, respectively. The unit cost and cost composition varied greatly between hospitals. There were four factors affecting the unit cost, namely clinical operation, efficiency, price and patient, among which clinical operation difference was the primary factor leading to cost difference. Conclusions The application cost of CRRT technology varies greatly among hospitals, and there are many factors affecting the cost. Public hospitals face great pressure in cost control. It is necessary to strengthen the internal control operation management of public hospitals, establish CRRT clinical operation standards, and improve the quality of medical services in public hospitals.
Objective To investigate the clinical significance of low dose corticosteroid applied in early period after lung volume reduction surgery（LVRS）. Methods From Apr. 2001 to Mar. 2004, 27 patients with chronic obstructive pulmonary disease were undergone video-assisted unilateral LVRS assisted with mini-incision in our department were retrospectively reviewed. According to whether dispensed with postoperative corticosteroid or not, patients were divided into corticosteroid group and non-corticosteroid group. Corticosteroid group received dexamethasone 10mg iv tid for 3 days and then declined to prednisone 5mg qd for 7 days. Both groups were measured and compared the quantity of thoracic drainage flow, duration of chest tube drainage, the time of air leaks and fever, and so on. At same time, blood gas analysis and blood routine test were performed at 1, 3, 7 and 30 d after operation. Results Corticosteroid and non-corticosteroid groups had no statistically differences in the air leaks time （P 〉 0.05）, but the quantity of thoracic drainage flow of corticosteroid group was lower than that of non-corticosteroid group evidently （700±210ml vs. 950±150ml, P = 0.001）. There was significant difference in average duration of chest tube drainage between both groups （9±3 d vs. 12±2 d, P = 0. 05）. Compared with non-corticosteroidgroup, PaO2 of corticosteroid group was higher at 1, 3d after operation （P〈0.05）. The amount of blood leukocyte of corticosteroid group was lower than that of non-corticosteroid group at 3, 7d after operation, there was no statistically significant in two groups （P 〉 0. 05）. At early period after surgery, both groups had no significant infection and death patient. Conclusion The low dose corticosteroid applied in early period after LVRS for short time（10 days in this research） could shorten the duration of chest tube drainage, decrease the quantity of thoracic drainage flow and the extent of inflammation in pleural cavity. In the mean time, this treatment does not increase the occurrence of significant complications during the early postoperative period, and there is no negative influence to the blood gas analysis.
Objective To investigate the expression of oncostatin M (OSM) in patients with sepsis and its role in early recognition of sepsis. Methods Thirty-four patients with sepsis admitted in Shanxi Bethune Hospital fromJune 3, 2021 to January 18, 2022 were selected as a sepsis group, 15 patients with community acquired pneumonia (CAP) as a case control group, and 16 adults who underwent physical examination in the same period were selected as a healthy control group. The patients in the sepsis group were followed up for 28 days and divided into a survival group and a death group. The serum OSM level and its correlation with clinical indexes (white blood cell, neutrophil, lymphocyte, sequential organ failure assessment score and acute physiology and chronic health evaluation Ⅱ) were analyzed, and the diagnostic value of OSM expression level in the early identification of sepsis was analyzed. Results Compared with the case control group and the healthy control group, the expression level of OSM in the sepsis group was significantly higher [(502.07±209.93)pg/mL vs. (368.22±65.95)pg/mL and (382.09±73.04)pg/mL, P<0.05]. However, the high expression of OSM had no significant correlation with white blood cell, neutrophil, lymphocyte or disease severity score (P>0.05), and there was no significant difference in serum OSM level between the sepsis survival group and the death group. Compared with white blood cell count, the high expression of OSM has certain diagnostic value in the early identification of sepsis. The area under the receiver operator characteristic curve of OSM in predicting sepsis was 0.794 (95% confidence interval 0.666 - 0.922, P<0.05), with the sensitivity of 79.4% and the specificity of 73.3%. Conclusion The expression of OSM in patients with sepsis is significantly increased, and the high expression of OSM has a certain diagnostic value in the early identification of sepsis.
Objective To investigate the medical charge of in-patients with diabetes and its influencing factors for effective hospital costs controlling. Methods The inpatients with diabetes (the first diagnosis was diabetes; the first three ICD-10 codes of which were between E10 to E14) in Fifth Peoples' Hospital of Chengdu during January to September of 2014 were analyzed for their hospital costs with descriptive statistical method, ANOVA and multiple linear regression method. Statistical analysis was conducted by using SPSS 18.0 software. Results A total of 1 389 cases of diabetes were included. The median of total medical costs and daily costs were 4 554.45 yuan and 446.46 yuan, respectively. The differences of total medical costs and daily costs between diabetes patients with different amount of complications were statistically significant (P<0.001). The factors including age, the way of the medical expense, the number of complications, with acute complications, CCI score and the hospital-stay length were proved to be significantly correlated to total medical costs of diabetes inpatients (P<0.05). Conclusion Age, the way of the medical expense, the number of complications, with acute complications, CCI score and the hospital-stay length are influence factors of medical costs of diabetes inpatients.
Objective Through the analysis of hospital costs of 16 866 cases of patients with lung cancer in Sichuan Province, in oder to find the main influencing factors of hospital costs of patients with lung cancer, and to provide references for reducing the hospital costs of patients with lung cancer. Methods We selected information of in-patients with lung cancer in 6 hospitals in Sichuan province from January 2008 to December 2011 based on full consideration into the local economic levels geographics distribution of different regions in Sichuan province. Then we extracted baseline data, hospitalization data and costs, and then analysis on relevant influencing factors was performed using single factor analysis of variance and multiple stepwise regression analysis. Results A total of 16 918 cases are chosen, of which, 16 866 were effective for further analysis. The results of statistical analysis showed that, the cost of western medicine accounted for the most of the average of the total hospital costs (50.79%) , followed by the cost of diagnosis and treatment (40.79%). The reuslts of multiple stepwise regression analysis showed that, the top three factors influencing hospital costs most included hospital stay, operation, and regions. Conclusion Facing daily increasing costs of hospital costs of lung cancer, effectively reducing drug expenses of patients could be a breakthrough. We could ultimately reduce the hospital costs of patients with lung cancer as well as the the economic burden of patients and society, by strengthening hospital management, shortening hospital stay, and rationally regulating drug use.
Objective To explore a scientific disease cost accounting. Method Disease cost accounting = disease cost accounting of clinic pathway + disease basis cost accounting. Conclusions It is the tendency with the medical reform for the social security department to pay by disease for the hospitals, as a result, both social security department and hospitals have to resort to the scientific way in terms of cost accounting of disease. And it is practical and effective by means of cost accounting for clinic pathway.
ObjectiveTo determine the effectiveness of continuous intercostal nerve block for pain relief after thoracotomy.MethodsFrom November 2017 to October 2018, 120 patients who received thoracotomy procedure in our hospital were collected, including 60 males and 60 females aged 40-77 (58.10±7.00) years. The patients were randomly allocated into three groups by digital table including a continuous intercostal nerve block group (group A, n=40), a single intercostal nerve block group (group B, n=40), and an epidural analgesia group (group C, n=40). All the groups received the same basic analgesia. The pain scores and rescue analgesic doses were compared.ResultsOn postoperative day (POD) 0, all groups achieved effective pain control, and the visual analogue score was 2.02±0.39 points in the group A, 2.13±0.75 points in the group B and 2.03±0.69 points in the group C (P>0.05). On POD 0-2 and POD 3-4 (without basement analgesia), there was no significant difference between the group A and group C in the pain scores (2.08±0.28 points vs. 1.93±0.53 points, 3.20±0.53 points vs. 3.46±0.47 points, P>0.05), however, the difference between POD 0-2 and POD 3-4 in each group was stastically different (group A, 2.08±0.28 points vs. 3.20±0.53 points; group B, 2.42±0.73 points vs. 5.45±0.99 points; group C 1.93±0.53 points vs. 3.46±0.47 points, P<0.05). In terms of the rescue analgesic doses, there was no significant difference between the group A and group C (220.00±64.08 mg vs. 225.38±78.85 mg, P>0.05); it was larger in the group B than that in the group A and group C (343.33±119.56 mg vs. 220.00±64.08 mg; 343.33±119.56 mg vs. 225.38±78.85 mg, P<0.05).ConclusionMultimodal analgesia is an optimal choice in the initial stage after thoracotomy surgery. Continuous intercostal nerve block is an effective way to pain management in patients with thoracotomy.
ObjectiveTo study effects of two kinds of epidermal growth factor receptor kinase inhibitors on bleomycin-induced pulmonary fibrosis in mice, and regulation mechanism on oncostatin M (OSM) and downstream signaling pathways.MethodsForty Kunming female mice were randomly divided into a control group, a fibrosis group, a gefitinib group, and an erlotinib group. The mice in the control group were administered with saline aerosol intratracheally. The mice in the fibrosis group were administered with bleomycin at a dose of 3 mg/kg aerosol intratracheally. The mice in the gefitinib group and the erlotinib group were administered with bleomycin at a dose of 3 mg/kg aerosol intratracheally and then gastrically perfused with gefitinib (20 mg·kg–1·d–1) or erlotinib (25 mg·kg–1·d–1). All mice accepted computer tomography examination 14 days after the treatment and then were sacrificed, and the lungs were collected for further detection. The lungs were stained with hematoxylin eosin and Masson’s trichrome, examined with Western blot for pathological examination and expressions of α-smooth muscle actin (α-SMA), OSM, Janus kinase 1 (JAK1), phospho-JAK1 (p-JAK1), signal transducers and activators of transcription 3 (STAT3), and phospho-STAT3 (p-STAT3) proteins.ResultsThe pathological injury of the lung in the gefitinib group and the erlotinib group was significantly relieved compared with that in the bleomycin group. The expressions of α-SMA, OSM, p-JAK1/JAK1, and p-STAT3/STAT3 proteins were also significantly reduced. There were no differences between the above-mentioned indexes between the gefitinib group and the erlotinib group.ConclusionsGefitinib and erlotinib can significantly relieve bleomycin-induced pulmonary fibrosis in mice. The underlying mechanism may be involved in inhibiting expression of OSM and downstream JAK/STAT pathways.
