Objective To evaluate the effect of the tention free repair on patient with abdominal insicion hernia. Methods 15 cases of abdominal insicion hernia were reviewed, all of them were repaired with polypropylene mesh. The mesh was overlaid on the defect, continuously monofilament nonabsorbable suture was used to fix the mesh on the edge of the defect and the mesh must be overlapped 2 cm on fascia abdominal layer and fixed by suture. Prophylactic antibiotics was used routinely in single dose. Result No relapse was found in follow up(rang 15～38 month). Conclusion The tension free hernia repair with polypropylene mesh in patient with abdominal incision hernia is a safe and simple operation with minimal postoperative pain.

Objective To explore the expression and significance of matrix metalloproteinase (MMP)-9, IV collagen and CD34 in epithelial ovarian tumor. Methods Eighty-two patients with epithelial ovarian tumor, among them,there were 48 malignant epithelial ovarian carcinomas, 23 borderline epithelial ovarian tumors and 11 benign epithelial ovarian tumors. The expression of MMP-9, IV collagen and CD34 were detected by immunohistochemistry. Results The expression of MMP-9 was strongly linked to the degree of malignant ovarian carcinomas (F= 39.306,P< 0.01). The expression of CD34 was also strongly linked to the degree of malignant ovarian carcinomas [benign epithelial ovarian tumors was (17.18±5.64)%,borderline epithelial ovarian tumors was (29.76±7.18)%,well-differentiated malignant epithelial ovarian carcinomas was (57.20±8.55)%,moderately-differentiated malignant epithelial ovarian carcinomas was (71.20±8.48)%, poorly-differentiated malignant epithelial ovarian carcinomas was(90.38±20.03)%](F= 100.072, P < 0.01). The expression of IV collagen in malignant epithelial ovarian carcinomas was different from that in borderline epithelial ovarian tumors and benign epithelial ovarian tumors (F = 11.554,P<0.0l). The expression of MMP-9 was positive correlation with the loss expression of IV collagen and the expression of CD34 (r=0.796,0.802,P< 0.01).Conclusions The positive expression of MMP-9,CD34 and the negative expression of IV collagen are obviously relevant to degree of malignant ovarian carcinomas.The combined testing on expression of MMP-9,CD34, IV collagen on ovarian carcinomas is significant to decide degree of malignant ovarian carcinomas and evaluate future development.

ObjectiveTo analyze the prevalence and influencing factors of mental health problems among hypertensive patients in Ya'an city five years after the Lushan earthquake， so as to provide references for promoting the mental health of hypertensive patients in earthquake-stricken areas. MethodsStratified random cluster sampling method was adopted to select 800 hypertensive patients in Ya'an city in December 2018. The general information of patients were collected via a self-designed questionnaire， and their mental health problems were assessed via the 12-item General Health Questionnaire （GHQ-12）.Then Logistic regression analysis was applied to explore the influencing factors. ResultA total of 744 valid questionnaires （93.00%） were obtained， and mental health problems were detected in 79 cases （10.62%）. Univariate analysis denoted that the detection rate of mental health problems yielded statistical difference among patients of different marital status （P<0.01）， family per capita monthly income （P=0.012） and social assistance recipients （χ²=25.194， P<0.01）. Logistic regression analysis indicated that the unmarried/separated/divorced/widowed status （OR=3.879， P=0.015） and social assistance recipients （OR=4.705， P<0.01） were risk factors for mental health problems among hypertensive patients. ConclusionThe detection rate of mental health problems is low among hypertensive patients in Ya'an city， while the unmarried/separated/divorced/widowed and social assistance recipients may suffer more serious mental health problems.

ObjectiveTo explore the effect of modified constraint-induced movement therapy (mCIMT) based on Chinese version of Quality of Upper Extremity Skills Test (Ch-QUEST) on upper limb function in children with hemiplegic cerebral palsy. MethodsFrom January to November, 2021, 40 children with hemiplegic cerebral palsy in Xuzhou Rehabilitation Hospital were recruited and randomly divided into control group (n = 20) and observation group (n = 20). The control group received routine upper limb function training, and the observation group received mCIMT based on Ch-QUEST additionally, for twelve weeks. They were assessed with Ch-QUEST, Peabody Developmental Motor Scale-Fine Motor (PDMS-FM) and Function Independence Measure for Children (WeeFIM) before and after treatment. ResultsAfter treatment, the scores of Ch-QUEST, DMS-FM (raw score) and WeeFIM significantly increased in both groups (|t| > 3.432, P < 0.01), and were higher in the observation group than in the control group (t > 2.032, P < 0.05). ConclusionmCIMT based on Ch-QUEST could improve the upper limb function of children with hemiplegic cerebral palsy.
