OBJECTIVE: To evaluate the safety and efficacy of Wuling Capsule combined with Deanxit in treating post-stroke depression (PSD). METHODS: One hundred and fourteen patients with PSD were randomly divided into Wuling Capsule-treated group (n=39), Deanxit-treated group (n=37) and Wuling Capsule plus Deanxit-treated group (n=38). Patients in Wuling Capsule-treated group were administered with three Wuling Capsules three times a day, and patients in Deanxit-treated group were administered with Deanxit 10.5 mg twice daily, while patients in the Wuling Capsule plus Deanxit-treated group were administered with both Wuling Capsule and Deanxit. Patients in the three groups were all treated for six weeks. Treatment efficacy was evaluated with Hamilton Depression Scale (HAMD) and the side effects were evaluated with Treatment Emergent Symptom Scale (TESS) before treatment and after 2-, 4-, and 6-week treatment. The blood and urine routine examinations were performed, and the hepatorenal functions and electrocardiogram were examined as well. RESULTS: There was no statistical difference in the total efficacy rate between Wuling Capsule-treated group and Deanxit-treated group (64.1% vs 64.9%, P>0.05), but the total efficacy rate of Wuling Capsule plus Deanxit-treated group was higher than that of the monotherapy (89.5% vs 64.1%, 89.5% vs 64.9%, P<0.05). There were no significant side effects in Wuling Capsule-treated group, while the incidence of side effects was 9% in both groups administered with Deanxit. CONCLUSION: The efficacy of Wuling Capsule plus Deanxit is better than that of the monotherapy in treating PSD.

Objective: To explore the relationship between the expressions of chemokine receptor CXCR4 and vascular endothelial growth factor C (VEGF-C ) with lymph node metastasis in human rectal cancer. Methods: Immuohistochemical staining was used to detect the expressions of CXCR4 and VEGF-C in 73 samples of human rectal cancer. The relationship between CXCR4 and VEGF-C in 73 samples of human rectal cancer. The relationship between CXCR4 and VEGF-C expressions was analyzed. Results: The positive rate of CXCR4 expression with lymph node metastasis was higher than that without lymph node metastasis (60.1% vs 23.3%,P

Objective:To observe the expression of chemokine receptor CCR7 and CXCR4 in human colorectal carcinoma and its significance,so as to assess their expression with the metastasis and prognosis of colorectal carcinoma. Methods:Immunohistochemistry was used to detect the expression of chemokine receptor CCR7 and CXCR4 in 110 patients with colon cancer.The relationship between the CCR7 and CXCR4 expression and the clinic pathological characters was statistically analyzed. Results:CCR7 and CXCR4 expression were positively expressed in 59.1% and 45.5%of the patients. The high expression rate of CCR7 and CXCR4 in lymph node metastasis positive cases was 81. 5% and 60.0% respectively,but the without lymph node metastasis positive cases were 26.7% and 24.4% respectively. The positive expression was significantely higher in the patients with lymph node metastasis than those non-lymph node metastasis(P

Objective: To explore the effect of CO 2 pneumoperitoneum in laparoscopic surgery on the cardiovascular function of the geriatric cholelithiasis.Methods:Sixty aged patients undergone laparoscopic surgery were selected.During various stage of CO 2 insufflation,the heart rate(HR),blood pressure,oxygen saturation ,electrocardiogram(ECG),and myocardial enzymes were dected,and the clinical values of these changes were analyzed.Results: when CO 2 pneumoperitoneum established ,the HR and blood pressure were increased obviously .The incidence of arrhythmia was 36% and the incidence of changes of ST segment was 30%,10 minutes after pneumoperitoneum eliminated,these changes were restored. The myocardial enzymes and the oxygon saturation of blood had no distinct changes. Conclusion: The procedure of CO 2 pneumoperitoneum caused temporany changes of the HR ,SBP/DSP and ECG.The laparoscopic surgery is effective and safe for geriatric cholelithiasis.It suggests that the dynamic monitoring of electrocardiogram is necessary,especially for those with abnormal heart function.

Objective To investigate the characteristics of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) of association fiber tracts in patients with amnestic mild cognitive impairment (aMCI), and to assess the application value of diffusion tensor imaging (DTI) in differential diagnosis of aMCI and AD. Methods DTI were performed in 20 patients of aMCI (aMCI group), 20 patients of AD (AD group) and 20 normal control subjects (control group). FA and ADC values were calculated in the regions of interest (ROI) in inferior fronto-occipital fasciculus (IFOF), genu and splenium of corpus callosum, superior longitudinal fasciclesⅡ (SLFⅡ) and cingulated bundles. Results There was significant difference of FA values in inferior fronto-occipital fasciculus and cingulate bundles between aMCI group compared with control group (P<0.05), as well as of FA values in cingulate bundles between aMCI group and AD group (P<0.05). Conclusion Abnormal FA values in inferior fronto-occipital fasciculus and cingulate bundles suggest that DTI can be used as a diagnosis index of aMCI. Furthermore, it is helpful in the differential diagnosis of aMCI and AD.

Objective To report a newly developed method and procedure to establish a rat model of subarachnoid hemorrhage in detail, and to provide a better model simulating the clinical subarachnoid hemorrhage caused by a ruptured aneurysm for related research.Methods One hundred and twenty healthy SPF 2-3-month old male Sprague-Dawley rats were divided into 4 groups, 30 rats in each group.The three experimental groups were sacrificed at 6, 24 and 72 hours after modeling.Rat models of subarachnoid hemorrhage were established by inserting a fiber core in the internal carotid artery and piercing this artery.Successful establishment of the subarachnoid hemorrhage model was confirmed by observation of breathing, pupil, defecation, urination and inspection at autopsy dissection.The controllability and reproducibility of this model were verified by observation of clinical manifestation and explored by mortality analysis.Results Subarachnoid hemorrhage was successfully induced by fiber core piercing the internal carotid artery at the needed location.Conclusions This method of model preparation is stable and understandable.The operation is nimble, with a good reproducibility.This model can be successfully performed after a short time learning, well simulate the sudden hemorrhage caused by a ruptured aneurysm, and suitable for research on early brain injury and vasospasm after subarachnoid hemorrhage.

Objective:To characterize the clinical and epidemiological changes, treatments, and prognoses of primary esophageal small cell carcinoma (PESC). Methods:A retrospective analysis was conducted using the clinical epidemiology data of 529 PESC patients se-lected from the clinical databases of 500,000 esophageal and gastric cardiac carcinomas of the Henan Key Laboratory for Esophageal Cancer Research (1992-2015). Among these patients, 241 cases were included in the survival analysis. The five-year survival rate was calculated using Kaplan-Meier analysis, and the differences in survival rates were compared using the Log-rank analysis model. Re-sults:All 529 PESC cases were analyzed, which accounted for 0.2%of esophageal cancers diagnosed in the same period. The incidence of PESC increased annually (R2=0.574). The survival rates for 1-, 2-, 3-, and 5-year of 241 PESC patients were 55%, 40%, 29%, and 9%, respectively, and the median survival time was 21.9 months. On the basis of the VALSG criteria of lung small cell carcinoma, a statisti-cal difference was observed in the overall survival rates for limited and extensive diseases (P=0.003), with the median survival time of 24.3 and 17.5 months, respectively. Furthermore, significant differences were observed on survival with various treatment modalities (P=0.004). The median survival time of PESC patients treated with combined surgery and radiochemotherapies (28.8 months) was lon-ger than those with either chemotherapy (17.8 months, P=0.015) or chemoradiotherapy (14.5 months, P=0.004). In limited disease pa-tients, the median survival time was longer in patients treated with surgery (27.7 months) than in those without surgery (16.2 months, P=0.007). Notably, the biopsy diagnosis before surgery for PESC was only 40.8%. Conclusion:PESC is a rare malignant carcinoma with increasing incidence. PESC presents poor prognosis, and the survival rate can be improved through combined therapies based on sur-gery. A high misdiagnosis rate for PESC is observed before surgery with biopsy.
