Objective To explore the age related decline in spine muscle volume and fat content in healthy elderly males . Methods Totally 88 males aged 50-79 years were selected from the patients who underwent quantitative CT (QCT) exam of lum‐bar spine .They were subgrouped by 50- <60 years ,60- <70 years and 70-79 years .The muscle fat area ,skeletal muscular area , muscle fat infiltration (MFI) ,abdominal visceral fat volume and subcutaneous fat volume ,abdominal total fat volume were measured by the QCT software .Statistical analysis was performed using intraclass correlation coefficient ,ANOVA with post hoc Bonferroni correction ,Pearson correlation analysis and multiple regression analysis .Results Compared to other two groups ,subjects in 70-79 years subgroup had highest muscle fat area/MFI and least skeletal muscular mass(P<0 .05) .Age‐dependent correlation was found in muscle fat mass(r=0 .381 ,P<0 .05) and MFI(r=0 .358 ,P=0 .001) ,but no obvious correlation was found between age and skeletal muscular mass .Age was the only factor entered into the all three paravertebral muscle composition regression equations , meaning age may had an important influence on paravertebral muscle degeneration .Conclusion Lumbar paravertebral muscle de‐generation in elderly men is correlated with the aging and MFI ,which may play a important role in the normative age‐related decline of skeletal muscle .

Objective To assess the prediction value of nonbronchial systemic arterial supply in hemoptysis patients with non-enhanced CT. Methods Fifty-six consecutive patients with hemoptysis underwent non-enhanced CT. Thickness of pleural adjacent to parenchymal lesion larger than 3 mm was regarded as index of nonbronchial systemic arterial supply. Conventional angiography was used as the standard of reference. CT findings were compared with those of conventional angiography. The sensitivity, specificity, and accuracy of CT for predicting nonbronchial systemic arterial supply were assessed. Results The sensitivity, specificity and accuracy of CT for predicting nonbronchial systemic arterial supply were 72.73%, 95.00% and 91.11%, respectively. Sensitivity was higher when nonbronchial systemic arterial supply located in superolateral and posterolateral lung, and lower in anteromedial and inferior lung. Specificity and accuracy were high for predicting nonbronchial systemic arterial supply in every locations. Conclusion Non-enhanced CT can predict nonbronchial systemic arterial supply in patients with hemoptysis, which is helpful for selecting angiography and embolization.

Objective To explore the relationship between psychological problems in middle school students and parental rearing behaviors.Methods It was a cross-sectional study.By means of cluster sampling,2700 students selected from 7 middle schools in Nanning were investigated with Symptom Check List-90(SCL-90),the Egna Minnen Barndoms Uppfostran(EMBU) scale and the General Information Questionnair.Results The prevalence of psychological problems was 14.5%.Correlation analysis showed that the total score and factor-scores of SCL-90 had positive correlation with parental punishment,rejection,preference and overprotection.The total score and factor-scores of SCL-90 was negatively related to parental emotional concern.Conclusions Psychological problems in middle school students are closely related to parental rearing behaviors,and incorrect parental rearing behavior is one risk factor of psychological problems in the middle school students.

Purpose To study the expression of HNF-1β in different type ovarian carcinoma and to explore the diagnostic value of HNF-1β in the diagnosis of ovarian clear cell carcinoma. Methods Immunohistochemical EnVision method was used to detect the ex-pression of HNF-1βin 27 clear cell carcinomas, 35 high-grade serous carcinomas, 21 endometrioid adenocarcinoma, 10 mucious carci-nomas, 13 metastatic Krukenberg tumors, and 2 transitional carcinomas. Results All of ovarian clear cell carcinomas variably ex-pressed HNF-1β and the positive rate of HNF-1β in ovarian cleat cell carcinoma was 85. 2%. Of 21 ovarian serous carcinomas, the nuclear positive of HNF-1β was 4 and HNF-1βpositive rate was 2. 9%. There was 5 HNF-1βexpression in endometrioid adenocarci-noma and the positive rate of HNF-1β was 23. 8%. The positive rate of HNF-1β in mucious carcinoma and metastatic Krukenberg tumor was 60. 0% and 53. 8%, respectively. No HNF-1βexpression was seen in transtional cell carcinoma. The sensitivity and speci-ficity of HNF-1β in the diagnosis of ovarian clear cell carcinoma was 85. 2% and 76. 5%. Conclusions HNF-1β may be a higher sensitive marker for the diagnosis of ovarian clear cell carcinoma. The diffuse and strong positive of HNF-1βmay have higher specific for diagnosis of ovarian clear cell carcinoma.

BACKGROUND:Recently, the clinical repair methods of irregular wound on fingers primarily include local pedicled flap and free mini-flap of upper extremities or lower extremities.
OBJECTIVE:To discuss the application of free mini-flap derived from upper limb in repairing the wound on fingers.
METHODS:From December 2010 to February 2014, 12 patients with irregular wounds on 12 fingers were selected from Department of Traumatic Orthopaedics and Hand Surgery, First Affiliated Hospital of Guangxi Medical University, China. The size of wounds ranged from 1.5 cm × 2.0 cm to 3.0 cm × 4.5 cm with different degrees of bone or tendon exposure. After the debridement, 12 patients were treated by free mini-flaps of upper limb. The donor sites were directly sutured.
RESULTS AND CONCLUSION:Among the 12 patients, al the wounds at recipient and donor sites were healed at stage I, and the free mini-flags survival completely. Al of patients were fol owed up for 3-6 months (average 4.5 months). Free mini-flags had good appearance and needn’t undergo secondary trimming. The active motion of fingers was improved dominantly. According to the criteria of Hand Surgery Association Society of Chinese Medical Association Society for the function evaluation of upper limb, three cases were excellent, eight were good, and only one was bad. The excellent and good rate was 91%. Free mini-flaps of upper limb are an ideal method for repair of wounds on fingers. It has no injury to normal tissue in hands, donor site is very secluded, and the short-term curative effect is good.
