Objective To analyze retrospectively the 875 procedures of earthquake related patient in West China Hospital of Sichuan University after the Wenchuan earthquake, so as to provide reference for the improvement of medical rescue for the disaster of earthquake and the establishment of state-level regional medical centers. Methods The analysis was based on the data provided by the Department of Information of the Hospital up until July 11. The software of Microsoft EXCEL was used for data input and statistical analysis. Results Up to July 11, 1 265 operations in earthquake injuries have been performed in the hospital, of which 875 were done in operating rooms. Initial peak of admission to hospital was positively correlated to peak of surgery performed, which the type of the operation was all emergency operation and most of which were amputation (43%). Second peak of surgery was 2 days delayed following admission to hospital. The type of operation mainly was elective surgeries. Most patients received second stage procedure-open reduction and internal fixation (61%). Conclusion Our hospital played a key part in rescue effort following such huge natural disaster. Our prompt response and effective leadership demonstrated our hospital’s flexibility and capability in the state-level hospital near the epicenter.
Objective To systematically evaluate the efficacy and safety of iris-registration in wavefront-guided LASIK (IR+WG LASIK) versus conventional LASIK for correction of myopia accompanied with astigmatism. Methods Such databases as PubMed, EMbase, The Cochrane library (Issue 2, 2012), CBM, CNKI, VIP, and WangFang Data were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about IR+WG LASIK versus conventional LASIK for correction of myopia accompanied with astigmatism. The retrieval time was from inception to February 2012, and the language was in both Chinese and English. Two reviewers independently screened the literature, extracted the data and assessed the quality of the included studies. Then the meta-analysis was performed by using RevMan 5.1 software. Results A total of 9 studies involving 3 903 eyes were included. The results of meta-analysis showed that, compared with the conventional LASIK group, the IR+WG LASIK group had a higher ratio in patients with postoperative uncorrected visual acuity no less than 1.0 (RR=1.03, 95%CI 1.01 to 1.05, P=0.002), as well as in patients with best-corrected visual acuity gained over 1 line (RR=1.75, 95%CI 1.49 to 2.16, Plt;0.000 01); it was smaller in the postoperative high order aberration RMS (WMD=?0.16, 95%CI ?0.21 to ?0.11, Plt;0.000 01), coma-like RMS (WMD=?0.05, 95%CI ?0.11 to 0.00, P=0.07), spherical-like RMS (WMD=?0.15, 95%CI ?0.23 to ?0.07, P=0.000 2), and residual astigmatism (WMD=0.14, 95%CI 0.10 to 0.18, Plt;0.000 01); moreover, it was lower in the incidence of postoperative glare (RR=0.27, 95%CI 0.15 to 0.50, Plt;0.000 1), and it was higher in the subjective satisfaction of patients (RR=1.08, 95%CI 1.04 to 1.13, P=0.000 3). Conclusion Compared with conventional LASIK, IR+WG LASIK can more effectively reduce astigmatism, postoperative high order aberration RMS and spherical-like RMS. It can also get visual function including uncorrected visual acuity and best-corrected visual acuity, consequently increase patient’s satisfaction. But further studies are still required for its long-term effect.
Object To investigate the constitution and expense of inpatient diseases in Jili Community Health Service Center (JCHSC) in Liuyang City of Hunan Province from 2008 to 2010, so as to provide baseline data for further study. Methods The questionnaire was applied and inpatient records in JCHSC between 2008 and 2010 were collected. The diseases were classified and standardized according to the International Classification of Disease, 10th Edition (ICD-10) based on the first diagnosis extracted from discharge records. Such information as general condition, discharge diagnosis and medical expenses etc. were analyzed by using statistic software of Microsoft Excel 2003 and SPSS 13.0. Results a) There were 9 chronic diseases and 6 acute ones among the top 15 single diseases, and both the average hospital stay and per-average hospitalization expense of chronic diseases were higher than those of acute ones (7.8 days vs. 5.6 days; ?2 733 vs. ?1551); b) Per-average expense of drugs as for both acute and chronic diseases accounted for nearly 50% of the total/general expense; c) There were 3 types of treatment models in JCHSC. Model A was only the internal medicine therapy, Model B was internal medicine assisted with surgery, and Model C was surgery assisted with internal medicine therapy; d) In detail, the total per-average expenses in JCHSC between 2008 to 2010 as for each single disease were as follows: coronary heart diseases (CHD, ?2 374 to ?2 680), urinary calculi (?3 268 to ?3 337), chronic bronchitis (?2 452 to ?2 488); e) Per-average hospitalization expenses in internal departments were ?1 719 to ?1 942 for acute diseases and ?2 386 and ?2 523 for chronic ones. Among surgical departments, the per-average hospitalization expenses as for acute diseases and chronic diseases were ?1 438 to ?1 579 and ?3 044 to ?3 607, respectively; and f) The average hospital stay for acute diseases in internal departments were 5.5 to 5.8 days for acute diseases and 6.9 to 7.3 days for chronic ones. By contrast, those in surgical departments were 5.9 to 6.2 days for acute diseases and 8.3 days for chronic ones, respectively. Conclusion a) In JCHSC, a total of 7 inpatient diseases among the top 15 single diseases in 2010 are all chronic with per-average total expense over ?2 000, which is higher than the average level of national CHSC (?2 357.6); b) According to the features of expense constitution models of the inpatient single diseases, the hospitalization expense should be controlled specifically; c) There are 3 kinds of diseases with yearly-increasing per-average total expenses as CHD, hypertension and pulmonary infection during recent 3 years; meanwhile, 4 diseases are with yearly-decreasing per-average total expenses as chronic bronchitis, cholecystolithias or accompanied with cholecystitis, diabetes and inguinal hernia; d) The per-average expenses of chronic diseases in surgical departments are higher than those in internal departments, but those of the acute diseases in surgical departments are lower. Meanwhile, the per-average total expenses as for both chronic and acute diseases in surgical departments present a decline trend year by year. Although the per-average expense on drugs as for both acute and chronic diseases in internal departments show a decline trend, the per-average total expenses indicate an ascending trend; and f) The average hospital stay of chronic diseases is longer than acute ones, while that of the surgical diseases is also longer than internal ones.
Objective Secondary osteoporosis is very common in patients with primary osteoporosis. Diabetes is a known cause of secondary osteoporosis. While type I diabetes has been clearly linked with diabetic osteoporosis, the effect of type II diabetes on bone health is controversial.Methods In the present study, we investigated the associations between type II diabetes and osteoporosis as well as fractures at different skeletal sites in Women’s Health Initiative participants.Results Common risk factors such as age, race, BMI, HRT use, and the history of fractures were significantly associated with osteoporosis and fractures in this study population. Diabetic women appeared to have a decreased risk of osteoporosis although it no longer remained significant after adjusting for other risk factors (crude HR=0.78, 95%CI 0.61 to 0.99; adjusted HR=0.93, 95%CI 0.73 to 1.19). The impact of diabetes on fractures varied at different body sites. There was a significant increase of risk of hip fracture (HR=2.54, 95%CI 1.14 to 5.66), but not spine fracture (HR=1.71, 95%CI 0.81 to 3.60) and arm fracture (HR=0.92, 95%CI 0.48 to 1.76) among the women with diabetes. Although the overall risk of fractures in diabetic women did not differ significantly from non-diabetic women (HR=1.37, 95%CI 0.89 to 2.09), the difference had a two-fold increase and was statistically significant after 2,000 days (HR=2.01, 95%CI 1.21 to 3.35), indicating a different hazard at different stages of diabetes.Conclusion Our findings suggest that type II diabetes may not be clearly associated with osteoporosis, it increases a site-specific fracture risk at least in the hip. In addition, the overall fracture risk appears to increase in a time-dependent manner.
ObjectiveTo analyze the status quo of outcome indicators in the randomized controlled trials (RCTs) of premature ovarian failure (POF)/primary ovarian insufficiency (POI) published at home and abroad, and provide a sufficient basis for the selection of outcome indicators in related studies in the future.MethodsChina National Knowledge Infrastructure, Chongqing VIP Data, Wanfang Data, SinoMed, PubMed, the Cochrane Library, and Embase were searched for RCT articles of POF/POI published between the establishment of the databases and June 2021. Two researchers independently screened and extracted the literature, and finally summarized the outcome indicators of the included studies.ResultsA total of 186 articles meeting the inclusion criteria were selected, including 180 articles in Chinese and 6 articles in English. The choice of outcome indicators was diverse. Of the 186 articles, 2 Chinese articles and 1 English article used primary and secondary outcome indicators; 19 Chinese articles and 4 English articles used independent indicators, 4 Chinese articles used composite indicators, and 157 Chinese articles and 2 English articles used both independent indicators and composite indicators.ConclusionsThe selection and use of outcome indicators in clinical RCTs of POF/POI are not standardized, and there are problems such as neglect of primary and secondary outcome indicators, and lack of standards for the selection of clinical research outcome indicators. As a result, the credibility of the curative effect is reduced, and the results of similar studies cannot be combined and compared.
ObjectiveTo observe and evaluate the predictive value of serum cystatin C (Cys-C) on the risk of sight-threatening diabetic retinopathy (STDR). MethodsA non-randomized controlled cross-sectional clinical study. Ninety-two patients with type 2 diabetes mellitus (T2DM) who were admitted to Department of Ophthalmology of Beijing Tsinghua Changgung Hospital from January 2022 to October 2022 were included in the study. Among them, 50 were male, 42 cases were female, with the mean age of (58.24±12.49) years. The mean duration of T2DM was (13.18±8.35) years, of which 38 cases had a duration of ≥10 years. Twenty-nine cases complicated with hypertension, of which 16 cases had a duration of ≥10 years. Seventeen cases complicated with chronic kidney disease stage 2 and 23 cases were treated with lipid-lowering drugs. Hemoglobin Alc, serum Cys-C, serum lipids and renal function were tested, and urinary microalbumin/creatinine ratio (ACR) was calculated. According to the 2003 American Academy of Ophthalmology "Clinical Guidelines for Diabetic Retinopathy (DR)" and international clinical DR severity grading standards, the patients were divided into STDR and non-STDR groups, with 44 and 48 cases in each group, respectively. STDR was defined as severe non-proliferative DR, proliferative DR, and macular edema. Logistic regression was used to analyze the independent risk factors of STDR in T2DM patients. Receiver operating characteristic curve (ROC curve) was used to calculate and analyze the area under ROC curve (AUC) and the predictive value of serum Cys-C and ACR in predicting STDR in T2DM patients. ResultsSerum Cys-C levels in STDR and non-STDR groups were 1.10 (0.94, 1.28) and 0.91 (0.83, 1.02) mg/L, respectively, with ACR of 4.29 (1.05, 21.89) and 1.39 (0.77, 3.80) mg/mmol, respectively. Compared with non-STDR group, serum Cys-C and ACR in STDR group were higher, and the difference was statistically significant (Z=－3.984, －3.280; P＜0.05). Multivariate logistic regression analysis showed that serum Cys-C was an independent risk factor for STDR (odds ratio=1.337, 95% confidence interval 1.145-2.090, P=0.033), and the risk of STDR increased by 33.7% for every 0.1 mg/L increase in serum Cys-C. ROC analysis results showed that serum Cys-C＞1.065 mg/L combined with ACR＞5.84 mg/mmol predicted the AUC of STDR in T2DM patients was 0.661, with the specificity of 95.8%. ConclusionsThe high serum Cys-C level is an independent risk factor for STDR in T2DM patients. Serum Cys-C has high predictive value for the occurrence of STDR.
ObjectiveTo explore the family function on patients with depression and its influential factors, in order to provide a basis for family support treatment for the patients. MethodsA total of 122 depressed patients from Mental Health Center of West China Hospital between February 2012 and June 2013, and one of their family members were chosen to be the study subjects. Another 122 non-clinical controls and one of their family members were recruited from a community near Sichuan University were regarded as the controls. All the subjects were asked to finish the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Family Assessment Device (FAD). Additionally, the patients received a diagnostic interview to provide the features of their depression. ResultsThe general average score of Q-LES-Q in families with depressed patients was significantly lower than that in the control families (t=-6.243, P<0.01). The general average score of each dimension in FAD for families with depressed patients was significantly higher than that for control families (t=3.644, 3.872, 2.694, 3.369, 5.369, 4.941, 5.241; P<0.01). According to FAD health division scoring, the unhealthy proportion in terms of communication, emotional reaction, emotional link, behavioral control and general function for families with depressed patients was significantly higher than that for control families (χ2=6.778, 23.698, 26.580, 39.875, 17.123, 10.712; P<0.05). The Q-LES-Q scores and the five FAD dimensional scores (except role and affective involvement) were negatively correlated (r=-0.388, -0.188, -0.200, -0.276, -0.370; P<0.05). The scores of perceived social support for families with depressed patients had significant positive correlations with the scores of all FAD dimensions except affective involvement (r=0.363, 0.345, 0.244, 0.418, 0.328, 0.457; P<0.05). The risk factors for unhealthy family function included: female (OR=1.141, P<0.05), poor education (OR=0.948, P<0.01), first-episode (OR=1.416, P<0.05), suicidal attempt (OR=1.014, P<0.05), incomplete suicide (OR=1.367, P<0.01) and depression episode number (OR=1.035, P<0.05). ConclusionDepression is associated with impaired family function in Chinese families. Female, poor education, first episode of depression, suicidal attempt, incomplete suicide and depression episode number are the influential factors for family function on patients with depression.
Objective To analyze the expression of apoptosis-related genes of retinal blood vessel in early diabetic rats by gene chip technology. Methods To make diabetic rat model by intraperitoneal injection of streptozotocin (STZ). On the 6th week after blood pressure increased, 10 rats were executed in Diabetic group and normal control group respectively. 20 retinal blood vessels were extracted and the RNA was isolated. The probe was made of alpha;-32 P-deoxyadenosine triphosphate (dATP)-labeled sample which hybridized 1176 nylon chips, and then analyzed by software. Three different expression genes were selected to verify by reverse transcription polymerase chain reaction (RT-PCR). Results On the 6th week, 136 （11.5％） genes were differentially expressed ［up-regulated genes were 90(7.6%), down-regulated genes were 46(3.9%)］in diabetic group. These genes involved into different groups according to their function. Especially in 72 apoptosis-related genes, 15 genes were differentially expressed. The up-regulated genes were some TNF receptor family members such as TNFRSF12, TRAIL, TNFRSF9, FADD；Bcl-2 family members such as bcl-w, bax, bak1 and AKT. The down-regulated genes were FAF1 which related to fas. Conclusions The expression of retinal vascular gene in early diabetic rats has been changed complicatedly. In particular, the multiple apoptosis-related genes have been changed in early diabetic, and most of them are at the upstream of apoptosis pathway. These findings indicate that the development of diabetic retinopathy is associated with multiple signaling pathways leading to apoptosis, while the alterations on the level of molecular biochemistry are still limited in apoptosis induction period. （Chin J Ocul Fundus Dis，2008，24：244-248）
Ultrasonic microfluidic technology is a technique that couples high-frequency ultrasonic excitation to microfluidic chips. To improve the issues of poor disturbance effects with flexible tip structures and the susceptibility of bubbles to thermal deformation, we propose an enhanced ultrasonic microchannel structure that couples flexible tips with bubbles aiming to improve the disturbance effects and the stability duration. Firstly, we used finite element analysis to simulate the flow field distribution characteristics of the flexible tip, the bubble, and the coupling structure and obtained the steady-state distribution characteristics of the velocity field. Next, we fabricated ultrasonic microfluidic chips based on these three structures, employing 2.8 μm polystyrene microspheres as tracers to analyze the disturbance characteristics of the flow field. Additionally, we analyzed the bubble size and growth rate within the adhering bubbles and coupling structures. Finally, we verified the applicability of the coupling structure for biological samples using human red blood cells (RBCs). Experimental results indicated that, compared to the flexible tip and adhering bubble structures, the flow field disturbance range of the coupling structure increased by 439.53% and 133.48%, respectively; the bubble growth rate reduced from 14.4% to 3.3%. The enhanced ultrasonic microfluidic structure proposed in this study shows great potential for widespread applications in micro-scale flow field disturbance and particle manipulation.
Objective To analyze the outcome of patients with Blunt Abdominal Injury (BAI) in the Deyang People’s Hospital after the Wenchuan Earthquake, in order to provide evidence for future improvement in emergency response after earthquakes and in the treatment of BAI patients. Methods Data on the BAI patients within 1 week after the earthquake were collected from the Information Department of the Hospital. Microsoft EXCEL was used for data input. Results A total of 23 BAI inpatients were treated, of whom 15 were from Mianzhu City and sent to hospital within 12 hours of the earthquake. This was 1.9% of the total inpatients. The BAI inpatients suffered severe and complex injuries, and 5 of them died (mortality rate: 22%). Linenectomy was conducted for patients with spleen injuries and two inpatients developed incision infection due to lack of antibiotics during the perioperative period. Conclusions It is important to establish an emergency response mechanism for medical rescue for patients with the viscera injury, including BAI, after an earthquake. This would help to guarantee rational allocation of the rescue workers, triage of the wounded, optimization of operation, as well as a reduction in mortality from BAI.
