Objective To investigate the clinical value of different treatments of uterine artery and vein in laparoscopic hysterectomy. Methods In 184 patients accepting lapaxoscopie hysterectomy, ligasttre vessel sealing system ,was applied to uterine vessels, while bipolar electric coagulation to coagulate the uterine vessels during the operation. Results Among the groups, women undergoing ligasure hand the smaller amount of estimated blood loss and was associated with shorter operating time, there were statistically significant differences among the two groups( P<0.01). Conclusion Each of the two operative ways is feasible or laparoacopic hysterectomy. The way of dissociating uteri arteriovenous completely before they were cut off with ligasure in laparoscopic panhysterectomy has many important clinical value such as easy appliance, safety, convenient operation, clear operation field and so on.

Chinese Journal of Primary Medicine and Pharmacy 2010;17(23):3175-3177
Objective To study the value of neoadjuvant chemotherapy in the treatment of cervical carcinoma. MethodsA clinical prospective study was carried out from Jan.1997 to Dec.2003,118 patients with cervical carcinoma were given two cycles of combined chemotherapy before operation(neoadjuvant chemotherapy group,group A).102 patients accepted surgery alone in our hospital from Jan.1997 to Dec.2003 were chosen as the comparison group(group B).Survival rate and complications were observed and analysed. Results5 year survival rate in group A was significantly higher than that in group B(P<0.01),The 5 year survival rate was significantly higher in group A than in group B,despite of different pathological types,with or without radiochemotherapy(P<0.05).The recurrent rate was lower in group A than that in group B,which show significant difference in the 5 year recurrent rate(P<0.05). ConclusionNeoadjuvant chemotherapy is an effective method for the treatment of cervical carcinoma in early stage.Because of satisfactory short-term control rate,excision rate,long-term survival rate and low recurrent and metastatic rate,neoadjuvant chemotherapy is worth popularizing in clinical treatment.

Objective:
To evaluate the risk of depressive disorders using memory task indicators, so as to provide insights into clinical assessment of depressive disorders.
Methods:
A total of 68 patients with depressive disorders undergoing treatments in the departments of psychiatrics and clinical psychology in a tertiary hospital during the period from January to September, 2021 were enrolled as the case group, while a total of 31 hospital employees, social volunteers and university students served as controls. The error rate and response time of classical memory task experiments were compared between the two groups, including implicit memory, short-term memory and working memory tasks. In addition, the predictive indicators of depressive disorders were identified using multivariable logistic regression analysis and receiver operative characteristics (ROC) curve.
Results:
The case group included 29 men and 39 women and had a mean age of (24.12±7.40) years, including 46 subjects with an educational level higher than diploma. The control group included 15 men and 16 women and had a mean age of (26.45±6.65) years, including 23 subjects with an educational level higher than diploma. Multivariable logistic regression analysis showed significant associations of age of >18 years (OR=3.431, 95%CI: 1.259-9.350), error rate of 2-back task (OR=1.056, 95%CI: 1.016-1.097) and error rate of short-term memory tasks (OR=1.078, 95%CI: 1.009-1.152) with the development of depressive disorders. ROC curve analysis showed that the error rate of 2-back tasks showed an area under the ROC curve (AUC) of 0.730 (95%CI: 0.630-0.831), cutoff of 22.5%, sensitivity of 42.6% and specificity of 93.5% for prediction of the risk of depressive disorders, and the error rate of short-term memory tasks showed an AUC of 0.717 (95%CI: 0.605-0.829), cutoff of 23.5%, sensitivity of 67.6% and specificity of 71.0% for prediction of the risk of depressive disorders. In addition, the combination of the error rate of 2-back tasks and the error rate of short-term memory tasks showed an AUC of 0.829 (95%CI: 0.734-0.923), sensitivity of 75.0% and specificity of 80.6% for prediction of the risk of depressive disorders.
Conclusion
Short-term and working memory task indicators are feasible for assessment of the risk of depressive disorders.

Journal of Preventive Medicine 2021;33(7):675-679
Objective:
To analyze the working memory impairment in patients with different degrees of depressive disorder and its influencing factors, so as to provide the basis for the clinical evaluation of cognitive function in patients with depressive disorder.
Methods:
From January 2019 to November 2020, the patients with depressive disorder were selected in the psychiatry and clinical psychology departments of a tertiary hospital. Demographic information, disease course and medication were collected. Depression subscale ( DEP ) of Mental Health Inventory ( PHI ) was used to measure the degree of depressive disorder. N-back tasks were used to test working memory, with error rate and reaction time as experimental variables to compare the working memory impairment of patients with different degrees of depressive disorder. The multivariate linear regression model was used to analyze the influencing factors for working memory impairment in patients with depressive disorder.
Results:
A total of 75 patients with depressive disorder were included, including 45 mild cases and 30 moderate and severe cases. The error rates of mild cases and moderate and severe cases in the 3-back task were ( 27.47±20.59 )% and ( 39.60±25.95 )%, the response time between the two groups in 0-back, 1-back, 2-back and 3-back task were ( 458.29±104.19 ) ms and ( 527.90±99.58 )ms,( 499.87±85.46 ) ms and ( 574.57±126.25 ) ms, ( 567.44±114.86 ) ms and ( 675.37±137.54 ) ms, ( 663.76±167.99 ) ms and ( 753.27±152.06 ) ms, the differences between two groups were significant ( P<0.05 ). The multivariate linear regression analysis showed that the severity of depressive disorder was correlated with the response time of 0-back to 3-back tasks and the error rate of 3-back task; whether patients took medicine or not was depressive disorder correlated with the 0-back task response time ( all P<0.05 ).
Conclusion
There are differences in working memory impairment among patients with different degrees of depressive disorder and the severity of impairment is correlated with the severity of depressive disorder and the use of antidepressant drugs.

Objective To investigate the clinical therapeutic effect of acupuncture on pulmonary infection after acute cerebral infarction.Methods Seventy patients with pulmonary infection after acute cerebral infarction were randomly allocated to treatment and control groups, 35 cases each. The control group received routine medication and the treatment group, acupuncture in addition. Pre-treatment and post-treatment National Institutes of Health Stroke Scale (NIHSS) scores and clinical pulmonary infection scores (CPIS) were compared between the two groups. The correlation between the NIHSS score and the CPIS score was observed.Results There were statistically significant pre-/post-treatment differences in the NIHSS score and the CPIS score in the two groups (P<0.05,P<0.01). There were statistically significant post-treatment differences in the NIHSS score and the CPIS score between the treatment and control groups (P<0.05). The correlation between the NIHSS score and the CPIS score was low in the treatment group after treatment (r=0.417,P<0.05).Conclusions Acupuncture plus medication is an effective way to treat pulmonary infection after acute cerebral infarction. It can improve the NIHSS score and the CPIS score in the patients.
