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.
ObjectiveTo systematically review the efficacy and safety of chemo-radiotherapy combined with hyperthermia (HCRT) for rectal cancer, and to provide evidence for clinical practice. MethodsWe searched the Cochrane Library (Issue 6, 2014), PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data databases from inception to July 2014. All relevant randomized controlled trials (RCTs) of HCRT for rectal cancer were collected. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 9 RCTs involving 663 patients were included. The results of meta-analysis showed that:Compared with the chemo-radiotherapy (CRT) group, the HCRT group were significant superior in complete response (OR=3.74, 95%CI 2.14 to 6.53), total effective rate (OR=4.23, 95%CI 2.69 to 6.66), 3-year survival rate (OR=4.48, 95%CI 1.81 to 11.06) and recurrence rate (OR=0.19, 95%CI 0.09 to 0.42). ②Compared with the radiotherapy (RT) group, the HCRT group was associated with significant improvement in complete response rate (OR=3.01, 95%CI 1.24 to 7.29). ConclusionCurrent evidence shows, HCRT is superior to CRT or RT in the treatment of rectal cancer. However, due to the limited quantity and quality of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo summarize regional and body distributions, diagnosis, treatment, and prognosis of echinococcosis outside liver in China. MethodsThe published literatures about echinococcosis outside liver in China (not including Hong Kong, Macao and Taiwan regions) from 2000 to 2015 were searched in the databases of CNKI and Wanfang. Data were extracted by using a standardized form and a retrospective clinical analysis was performed. ResultsA total of 66 published literatures about echinococcosis outside liver and data of 884 cases reported were collected. The regional proportions of cases reported were different, five high regions were Xinjiang (68.73%), Tibet (8.77%), Ningxia (6.75%), Qinghai (6.41%), Gansu (5.62%). The organ distributions of cases reported were also different, five high organs were lung (61.09%), bone (9.95%), brain (9.73%), spleen (8.60%), and kidney (6.22%). The main clinical symptoms of patients with echinococcosis outside liver included general asymptoms and organ dysfunction, and the most common examinations were X-ray (30.77%), B ultrasound (7.47%),CT(17.43%), MR (1.59%), and laboratory (36.31%). The main therapy choice was operation (73.30%), and some patients were performed operation combined with drug therapy. ConclusionRegional distribution of echinococcosis outside liver is almost the same as total echinococcosis, and distributed more in organs rich in blood supply, its clinical diagnosis mainly depends on imaging and immunology examination, and operation is still the main therapy choice.
Objective To provide references for the rational allocation of health personnel in rural hospitals through understanding the status of health human resources of rural hospitals in remote and poor areas of Sichuan Province. Methodes This study used cluster sampling method, combined with questionnaire survey and qualitative interviews. A total of 711 health workers of 29 rural hospitals in Pengzhou and Baoxing of Sichuan Province were interviewed. SPSS16.0 was used for descriptive analysis.Results The average age of rural hospitals health personnel in remote and poor areas of Sichuan Province was 30 years old. Post-secondary education accounted for 58.12%, and Bachelor degree or above accounted for 7.2%. The number of medium and senior professional titles account for 8.4 %. The ratio of doctors to nurses was 1:0.55. In the survey of health workers, those doctors with practice (assistant) license accounted for 38.5%, and those without any qualification occupied 27.1 %. Conclusions The professional titles of medical personnel of rural hospitals in remote and poor areas in Sichuan province are generally low. The distribution of professional categories is irrational. The staff in charge of prevention and care are inadequate. There exist a large number of unqualified medical workers. Therefore, the government should increase the investment in rural health and take measures to stabilize the team structure, introduce the talented, and strengthen the training for health personnel of rural hospitals to improve their overall quality.
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）
Objective To explore the correlation of risk factors affecting the L2-4BMD level in patients with post-menopausal osteoporosis. Methods Ninety-two patients with post-menopausal osteoporosis were surveyed with a retrospective questionnaire. We used the findings to set up a multiple stepwise regression model and perform correlation analysis with L2-4BMD levels as the dependent variable and risk factors as the independent variables. Results Assuming that age has a definite effect on the L2-4BMD level of menopausal women, menopausal age limit, history of milk drinking, menopausal age, menarche age, fracture history and bend-back entered into the multiple stepwise regression equation. Conclusions Menopausal age limit, history of milk drinking, menopausal age, menarche age, fracture history, and bend-back influence patients with menopausal osteoporosis.The menopausal age limit is especially important. Awareness of the risk factors of osteoporosis should be raised.
ObjectiveTo analyze the 2023 learning society construction project in order to provide references for researchers in this field. MethodsExcel 2021 software was used to summarize and comb the list of key tasks for the construction of a learning society in 2023 (field of higher continuing education) published on the official website of the Chinese Ministry of Education, and to visually analyze the research topics of key tasks in the medical field and the distribution of applicants. ResultsThe analysis found that a total of 250 projects were shortlisted in the cultivation and construction list, including 100 teaching reform and innovation tasks of continuing education for academic degrees, 100 reform and innovation tasks of non-academic education, and 50 tasks to explore the path of coordinated innovation of the three education. The project involved digital transformation, education and teaching reform, ideological and political education, etc. There were 17 medical projects, accounting for 6.8% of the total number of key tasks. The 17 medical key task declaration units were distributed in 12 provinces (regions), which were mainly concentrated in East China, and the construction of "non-double first-class" universities as the main force; The results mainly focused on personnel training and education and teaching reform. ConclusionThe analysis results of the key task list of 2023 learning society construction (field of higher continuing education) provide important references and enlightenment for the researchers in the field of education, and provide guidance and references for the future development of higher continuing education.
Covariates are factors which have significant impacts on the primary analysis prior to the subjects being treated. Covariates adjustment should be considered in the design and analysis stages of the clinical trial. Through controlling in the design stage is the optimal resolution; randomization, stratified randomization and restricted covariant values could be used to balance the covariates between comparative treatments. During data analysis stage, analysis of covariance, stratified analysis, linear or generalized linear model can be conducted for covariate adjustment according to different types of outcome and covariate. For confirmatory clinical trial, covariates should be defined in advance in the protocol and statistical analysis plan with the main statistical model.
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 determine the risk factors for acute lung injury（ALI） early after orthotopic liver transplantation.Methods The perioperative clinical data of all 275 patients who had undergone orthotopic liver transplantation were analysed retrospectively.Several statistically significant risk factors were screened out with univarite analysis，then independent risk factors were determined with multivariate stepwise logistic regression analysis.Results Of the all 275 patients，the morbidity of ALI was 9.8% with a mortality of 22.2%.Univariate analysis showed that the occurrence of ALI was associated with preoperative infection，severe hepatitis，renal dysfunction，massive blood transfusion in operation，long non-hepatic period and long cold ischemic time.Multivarite stepwise logistic regression analysis revealed that the independent risk factors for ALI were massive blood transfusion in operation（OR=12.12，95%CI 0.958-25.364），longer non-hepatic period（OR=1.23，95%CI 1.034-1.410） and longer cold ischemic time（OR=22.35，95%CI 1.266-43.421）.Conclusion Massive blood transfusion in operation，long non-hepatic period and long cold ischemic time were independent risk factors for ALI early after orthotopic liver transplantation.
