Objective:To investigate the expression of hippocampal synapse-related proteins including synaptophysin (SYN), postsynaptic density protein 95 (PSD95) and growth-associated protein 43 (GAP43) in rats with epilepsy accompanied by depression.Methods:The 3-month-old female clean grade SD rats were selected for the experiment.Lithium chloride pilocarpine was used to establish an epileptic rat model. Rats with successful epilepsy models were divided into epileptic depressive group (EWD group)and epileptic group with 10 in each group based on whether they were accompanied by depression. Furthermore, ten rats with matched body mass were taken as the depressive group and 10 were taken as control group. As for the depressive group rats, chronic unpredictable mild stress stimulation combined with orphanage was adopted to establish a model of depression.The depressive behaviors of rats were evaluated by body mass, sucrose preference test and open field test. Immunohistochemical staining and Western blot were used to detect the expression of SYN, PSD95 and GAP43 proteins in rat hippocampal tissue. SPSS 17.0 software was used for data statistical analysis, repeated measurement ANOVA was used for behavioral results, one-way ANOVA was used for inter group comparison of protein expression data, and LSD test was used for further pairwise comparison.Results:As for the body mass, there was significant interaction effect between the time and group among the 4 groups ( F=7.33, P<0.01). On the 8th day and the 29th day, the body weight of rats in the EWD group and the depressive group were lower than those in the epilepsy group (all P<0.05). The body weight of rats in the EWD group on the 29th day was lower than that on the first day ( P<0.05). As for the sucrose preference rates, there was significant interaction effect between the time and group among the 4 groups( F=2.67, P<0.05). The sucrose preference rate of EWD group on the15th and 29th day were lower than that on the first day (both P<0.05). The results of the open field test showed that the interaction effects of the number of vertical standing times( F=2.74) and the number of horizontal movement lattices ( F=1.76) both were not significant (both P>0.05), but both the time effect and group effect were significant (vertical standing times: Ftime=4.35, P<0.05, Fgroup=25.64, P<0.01; horizontal movement lattices: Ftime=12.75, P<0.01, Fgroup=21.37, P<0.01). The immunohistochemical results showed that there was a statistically significant difference in the number of positive cells expressing synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=93.85, 58.66, 98.84, all P<0.05). The numbers of positive cells of SYN (11.73±4.30), PSD95 (24.47±7.58) and GAP43 (9.40±3.50) in the epilepsy group were lower than those in the control group ((51.00±15.39), (55.60±13.17) and (29.53±4.05)) (all P<0.05). The numbers of positive cells of SYN (5.80±3.53), PSD95 (12.87±4.03) and GAP43 (5.33±3.50) in the EWD group were lower than those in the depressive group ((11.33±3.22), (48.13±12.69) and (15.47±5.21) )(all P<0.05). Western blot results showed that there were statistically significant differences in the expression of synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=13.19, 9.38, 16.80, all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the epilepsy group were lower than those in the control group (all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the EWD group were lower than those in the epilepsy group and the depressive group (all P<0.05). Conclusion:The low expression of SYN, PSD95 and GAP43 proteins in the hippocampus of rats with epilepsy accompanied by depression may be related to their pathogenesis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

A total of 231 patients aged>60 years who underwent orthopedic surgery in Department of Orthopedics of Emergency General Hospital from November 2019 to June 2022, were enrolled. All patients received a comprehensive geriatric assessment before surgery. The demographic characteristics, medical history of patients were collected, the geriatric syndrome, postoperative complications were analyzed. The risk factors of postoperative complications were analyzed with Logistic regression. The preoperative comprehensive geriatric assessment showed that the most common geriatric syndrome was cognitive impairment (29.9%, n=69), followed by frailty (14.3%, n=33), nutritional risk (10.4%, n=24), functional dependence (7.8%, n=18), depression and anxiety (3.9%, n=9). Postoperative complications occurred in 38 cases, including delirium in 18 cases (7.8%), respiratory infection in 15 cases (6.5%), heart failure in 9 cases (3.9%) and death in 1 case (0.4%). The Logistic regression analysis showed that anemia ( OR=5.278, 95% CI:1.237-22.518), frailty ( OR=2.865, 95% CI:1.049-7.829) and cognitive impairment ( OR=3.796, 95% CI:1.526-9.442) were independent risk factors for adverse postoperative outcomes ( P<0.05). The study indicates that incidence of preoperative geriatric syndrome in patients undergoing evaluation is common; and anemia, frailty and cognitive impairment may be related to adverse clinical outcomes in elderly patients after surgery.

Objective:To systematically evaluate the clinical efficacy of fire needle therapy and conventional western medicine in the treatment of patients with acute herpes zoster.Methods:Randomized controlled trials (RCTs) of fire needle therapy in the treatment of acute herpes zoster were retrieved from China National Knowledge Internet (CNKI), Wanfang, Database of Chinese Sci Tech Periodicals (VIP Database), China Biomedical Literature Database (CBM), Medline, Embase, and Cochrane Library from the establishment of the databases to May 30, 2022. According to the inclusion and exclusion criteria, the included literature was screened, and Review Manager 5.3 was used for system evaluation and meta-analysis.Results:7 articles were included for analysis after screening, involving 452 patients. There were 226 cases in the treatment group and 226 cases in the control group. The results of meta-analysis showed that fire needle therapy was superior to conventional western medicine in the total effective rate [ RR=0.36, 95% CI (0.20, 0.65), P=0.000 7], lower incidence of PHN [ RR=0.25, 95% CI (0.09, 0.72), P=0.01], lower VAS score [ MD=-1.19, 95% CI (-2.14, -0.24), P=0.01], and shorter scab forming time [ MD=-2.03, 95% CI (-2.42, -1.64), P<0.001]. Conclusion:The curative effect of fire needle therapy is more prominent than that of conventional western medicine in the treatment of acute herpes zoster.

Objective:To test the reliability and validity of a multi-dimensional, quantitative video evaluation system (the Multi-dimensional system) for evaluating hand dysfunction among stroke survivors so as to provide an objective basis for its clinical application.Methods:Sixty stroke survivors with single dysfunctional hand were evaluated using the Multi-dimensional system and also using the Fugl-Meyer Upper Extremity Assessment (FMA-UE) and the Action Research Arm Test (ARAT) and in terms of their active range of hand motion (AROM-H). The Multi-dimensional system′s internal consistency, composite reliability, split-half reliability, parallel-forms reliability as well as intra- and inter-observer reliability were quantified. Its validity was tested in terms of content validity, structural validity, convergent validity and criterion validity.Results:The system′s Cronbach′s α was determined to be 0.86. Its one-dimension composite reliability was 0.939, its split-half reliability coefficient was 0.88 and its parallel-forms reliability was 0.922. The inter-evaluator reliability was between 0.965 and 0.998 [95%CI= (0.919, 0.999)], and the single evaluator ICC value was 0.973 to 0.998 [95%CI= (0.937, 0.999)]. The validity test produced a content validity index of 1, and the Pearson correlation coefficients between each sub-item and the total score were all greater than 0.60. The KMO value for structural validity was 0.882, and there was a common factor in the component matrix which reflected 60.9% of the information in the original variables. The system′s convergent validity AVE was 0.609 with Pearson correlation coefficients between the multidimensional system and the FMA-UE and ARAT both > 0.70.Conclusion:The multi-dimensional quantitative video evaluation system has good reliability and validity in the evaluation of stroke survivors with hand dysfunction.

Objective:To develop and validate a preoperative prediction model based on laboratory parameters in differentiating intrahepatic cholangiocarcinoma (ICC) from hepatocellular carcinoma (HCC).Methods:Data from 833 patients with primary liver cancers treated at the First Affiliated Hospital of Nanjing Medical University between January 2016 and May 2020 were retrospectively analyzed. There were 652 males and 181 females, aged (59.0±11.1) years, with 649 patients diagnosed to have HCC and 184 patients ICC. Based on the different admission time, they were divided into a development cohort ( n=577) and a validation cohort ( n=256). Logistic regression analysis was used to identify independent differential factors which were then included in the nomogram. The discrimination and calibration ability of the nomogram were evaluated by using concordance indexes (C-index) and calibration curves. Results:Female ( OR=4.989, 95% CI: 2.547-9.772), hepatitis B surface antigen positivity ( OR=0.144, 95% CI: 0.074-0.279), α-fetoprotein (21-399 ng/ml, OR=0.142, 95% CI: 0.072-0.283; ≥400 ng/ml, OR=0.023, 95% CI: 0.006-0.095), carcinoembryonic antigen (>4.7 ng/ml, OR=2.667, 95% CI: 1.352-5.261) and carbohydrate antigen 199 >39 ng/ml ( OR=11.019, 95% CI: 5.739-21.159) were independent differential factors for ICC. A nomogram was established by incorporating these 5 factors. The C-indexes were 0.942 (95% CI: 0.919-0.965) and 0.949 (95% CI: 0.914-0.985) in the development and validation cohorts, respectively. Calibration curves showed good agreement between the predicted risk by the nomogram and real outcomes. Conclusion:In this study, a preoperative nomogram for differential diagnosis between ICC and HCC was established. The model could aid clinicians in clinical treatment decision making.

Objective To investigate the clinical diagnostic value of circulating tumor cells (CTCs)and circulating cell-free DNA (cfDNA) in peripheral blood samples in breast cancer. Methods From July 2017 to April 2018, 47 patients with BMC (7 in stage Ⅱ, 19 in stage Ⅲ and 21 in stage Ⅳ), 24 patients with benign breast diseases and 28 healthy people were selected. After collecting peripheral blood samples, serum and blood cells were separated. The size-based high-throughput microfluidic chip was used to capture CTCs. The real-time fluorescent quantitative PCR based on Alu sequence was used to detect the length of cfDNA(247 bp, 115 bp)in the serum, and the ratio of amplified products of long and short fragments was used as the index of DNA integrity. The Mann-Whitney U test or Kruskal-Wallis H test was used to compare the differences between the groups and analyze the relationship between CTCs and cfDNA and clinical parameters of breast cancer. The ROC curve was drawn and the area under the curve (AUC) was used to evaluate the feasibility of blood cell CTCs and plasma cfDNA detection as diagnostic criteria. Results The CTCs and cfDNA of 47 BMC patients were analyzed. The CTCs and cfDNA integrity index (Alu 247/115) of BMC patients were significantly higher than those of physical examination patients[(13.98± 12.36)cells / ml vs (1.14 ± 1.35) cells / ml; 0.7687 ± 0.3868 vs 0.5094 ± 0.2456], and the difference was statistically significant(the U value was 126.5,359.0;P<0.001), the area under ROC curve of CTCs was 0.885 (95％CI: 0.805-0.965), cut-off value was 7.68/ml, sensitivity was 80.4％, specificity was 96.4％. The area under ROC curve of Alu 247/115 was 0.727(95％CI: 0.608-0.847), cut-off value was 0.431, sensitivity was 71.7％, specificity was 71.4％. The AUC of CTCs and Alu 247/115 was 0.919 (95％CI 0.854-0.984), which was higher than the single test of each indicator. Conclusions CTCs and cfDNA may be the potential biological indicators for breast cancer diagnosis. The combined detection of CTCs and cfDNA maybe improve the diagnosis rate of breast cancer patients.

Objective:To investigate the role of interleukin-10 (IL-10) and IL-12 in the differential diagnosis of tuberculous and malignant pleural effusion through measuring the serum and pleural effusion IL-10 and IL-12 levels of tuberculous and malignant pleural effusion patients.Methods: Forty-eight inpatients with exudative pleural effusion who didn''t receive any treatment before were selected.According to the pathogeny, the patients were divided into tuberculous pleural effusion group (n=25) and malignant pleural effusion group (n=23).The levels of IL-10 and IL-12 in peripheral blood and pleural effusion of the patients in two groups were detected by Cytometric Bead Array (CBA).The differences in IL-10, IL-12 levels and IL-12/IL-10 ratio were compared between two groups.The ROC curves of the above indexes, cast-off and adenosine deaminase (ADA) were used to compare the effects in differential diagnosis of tuberculous and malignant pleural effusion.Results: There were no statistical differences in the levels of serum IL-10, IL-12 and IL-12/IL-10 ratios of the patients between tuberculous and malignant pleural effusion groups (P>0.05),and the IL-12 level in pleural effusion and the IL-12/IL-10 ratio of the patients in malignant pleural effusion group were lower than those in tuberculous pleural effusion group (P<0.005).The area under the ROC curve for the levels of IL-12 in pleural effusion (0.984) was higher than those for the ratio of IL-12/IL-10, cast-off and ADA (0.744, 0.804 and 0.911, respectively) in the differential diagnosis of tuberculous and malignant pleural effusion.Conclusion: The detection of IL-12 levels in pleural effusion is helpful for the differential diagnosis of tuberculous and malignant pleural effusion, and the pleural effusion is easy to obtain, therefore the detection of IL-12 in pleural effusion is worth to be widely applied in clinic.

Objective To explore the effect of self-designed two-level prevention list in the care to patients with coronary heart disease(CHD)treated with percutaneous coronary intervention(PCI). Methods Seventy-four CHD patients having undergone PCI during October 2013 and October 2015 were randomly divided into the control group and the observation group equally.In the control group,the routine outpatient visit every 3 months was done without any intervention.Apart from the routine outpatient visit,in the observation group,a phone call follow-up every half month was done with intervention on the medication and lifestyle using the self-designed secondary prevention list.The two groups were compared in terms of blood fat,blood pressure,medicine-taking compliance and lifestyle. Results After 6 months follow-up,there were insignificant differences in medication compliance of four drugs between the two groups (P>0.05),but there were significant differences between them in blood fat,blood pressure and lifestyle (P<0.05),where the total cholesterol,low density lipoprotein and systolic blood pressure were significantly lower than those of the control group,while the smoking-quitting rate and the physical exercise qualification rate were significantly higher (all P<0.05). Conclusion The self-designed two-level prevention list is effective in improving the lifestyle of the CHD patients after PCI,good for the control of blood fat and pressure.

Objective To study effect of targeted nursing cooperation on complications of endoscopic thyroidectomy.Methods A total of 104 patients with endoscopic thyroidectomy in our hospital were divided into study group and control group by random number table method,with 52 cases in each group.Control group conducted conventional nursing for endoscopic thyroidectomy,study group conduced targeted nursing cooperation on the basis of the control group.Operation time,postoperative volume of drainage,length of hospital stay,and intraoperative complications were compared.Results No significant differences in operation time and volume of drainage between two groups were found(P ＞0.05);Incidence rate of complications and length of hospital stay were lower than that in the control group (P ＜ 0.05).Conclusion Targeted nursing can effectively reduce incidence rate of complications in endoscopic thyroidectomy,speed up the recovery,and had no significant effect on operation time and postoperative volume of drainage,so it is suitable for clinical promotion.
