Objective To investigate the feasibility and safety of periareolar incision in treating gynecomastia, and whether it produces good cosmetic effects. Methods A total of 42 patients with gynecomastia treated by micro-incision of areola were retrospectnely anslyzed. Results The operation was successfully performed in all the 42 patients. Follow-up was done for 3 to 24 months, the surgical scars were obscure, and the sensation of nipple or areola were good. No operation-related complications were observed. Conclusion The periareolar incision in the treatment of gynecomastia was feasible and recommendable in terms of cosmetic maintenance and safety.

sweet potato. Conclusion The content of arsenic (Ⅲ) in the edible part of plants was one of the important factors for selecting the plants that are suitable for growing the arsenic polluted area.

Objective To explore the method and result of endoscopic thyroidectomy. Methods Thyroidectomy was performed endoscopically in 4 cases of thyroidoma. Results 4 patients underwent endoscopic thyroidectomy, whose operation time was 52,63,70,75 minutes respectively. An average blood loss during operation was 35ml and no complication occurred. They were discharged 4 days～5 days after operation. Conclusions The endoscopic thyroidectomy has the advantages of minimal invasion, less bleeding, less complication and quicker recovery.

Objective To evaluate the clinical value of ultrasonography in diagnosis of benignPHand malignant thyroid nodules by binary Logistic regression model.Methods A retrospective analysis of 240 cases of thyroid nodules confirmed by pathology after operation excision was conducted.173 nodules were benign as control group,67 nodules were malignant as observation group.The ultrasonic features of thyroid nodules were collected.The factor had statistics significance by x2 test between the two groups were analyzed by binary Logistic regression.A logistic regression model was created.The ROC curve was drawn and the area under the curve was calculated.Results There were statistically significant differences among boundary,aspect ratio,shape,internal echo,calcification,acoustic halo,cervical lymphadenectasis between the control group and observation group(x2=45.392,7.590,30.039,24.168,37.406,6.893,16.078,all P<0.01).And after Logistic regression analysis,six variables that entered the regression equation were boundary(P=0.000,OR=8.437),aspect ratio(P=0.000,OR=12.816),microcalcification of the nodules(P=0.000,OR=8.893),shape(P=0.000,OR=8.791),internal echoes(P=0.001,OR=8.313)and cervical lymphadenectasis(P=0.001,OR=6.891).The accuracy of the model was 90.7%(223/246)in predicting malignant nodules in thyroid.The area under the ROC curve was(0.904±0.031).Conclusion The binary Logistic regression can be used to differentiate malignant and benign thyroid nodules,and make a more accurate judgment for the nodules in thyroid.

Objective To explore the effect of lipide on mice podcyte prolixferation in vitro culture.Methods MTT was used to dectect the change of the Podocyte Proliferation after the inducement of low-density-liportein(LDL)and oxide-LDL(OX-LDL).Results After 24 and 48 hours,the mice podocyte proliferation increased with the inducement of LDL,which the thickness from 6.25?g/ml to25?g/ml.And after 24 hours,the podocyte proliferation increased with the OX-LDL,which the thickness from 12.5?g/ml to 100?g/ml(compared with control,P

Statistical analysis of TCM syndrome differentiation and clinical symptoms were made in 163 cases of diseases of digestive tract. It was found that the patients of abnormal defection or tendecy of abnormal defecation with the hyperactive liver - Qi attacking the spleen, stagnation of liver-Qi due to hypofunction of the spleen, loose stool due to deficiency of the spleen, constipation due to Qi-deficiency, constipation due to Qi - staganation syndromes accounted for 60%- 100%. Elecrtic examination of colon on the body surface and analysis of frequancy spectrum found that hyperelectroactivity of low - frequency and high - frequency segment of colon and contractive complex myoelectric hyperactivity in the patients of the hyperactive liver - Qi attacking the spleen; hyperelectroactivity of high - frequency segment of the ascending and descending colon and contractive complex myoelectric hyperactivity and decrease of electric activity of high - frequency segment of the sigmoid colon in the patients of loose stool due to hypofunction of the spleen: obvious decrease of electric activiy of low - frequency and high-frequency of the colon and contractive complex myoelectric hyperactivity in the patients of constipation due to deficiency of Qi or Qi - stagnation, but electric activity of the high -frequency segment of the colon and contractive complex myoelectric activity after meal in the patients of constipation due to Qi -stagnation was stronger than that in the patients of constipation due to Qi - deficiency. Electric frequency spectrum of colon can indirectly reflect changes of colon dynamics of different syndromes, and it can partially expain the changes of stool and the mechanism of relative symptoms.

OBJECTIVE:To evaluate the quality of the methodology of clinical research on Yinzhihuang injection in the treatment of icteruc virus hepatitis.METHODS:The methodology quality of77pertinent literatures was evaluated and analyzed according to the quality assessment criteria in the evaluation manual of Cochrane Reviewer's Handbook 4.2.2.RESULTS:Only 4 literatures were up to the related standards,2 of which were randomized controlled trials(RCT)and other 2 were semi-randomized controlled trials(CCT).All of the 4 studies were low quality(Grade C)researches,in which the biases on selectivity,practice,measurement and wastage were highly possible.CONCLUSION:More randomized controlled trials of high quality are needed to obtain reliable evidences on Yinzhihuang injection in the treatment of icteric virus hepatitis.

Objective To investigate the effect of acupuncture at Huatuo jiaji points plus virtual balancing game on balance function in stroke patients.Methods Fifty patients with poststroke balance dysfunction were randomly allocated: 25 cases to the treatment group and 25 cases to the control groups. The treatment group received acupuncture at Huatuo jiaji points plus virtual balancing game-based rehabilitation training and the control group, virtual balancing game-based rehabilitation training alone. The Berg Balance Scale (BBS) score, the Timed Up and Go Test (TUGT) score, the COP offset distance indices (EO2, EC2, EOTS and EO1) and the modified Barthel Index (MBI) score were recorded in the two groups before and after treatment.Results There were statistically significant pre-/post-treatment differences in the BBS score, the TUGT score, the COP offset distance indices and the MBI score in the two groups of patients (P<0.05). There were statistically significant post-treatment differences in the BBS score, the TUGT score, the COP offset distance indices and the MBI score between the treatment and control groups (P<0.05).Conclusion Acupuncture at Huatuo jiaji points plus virtual balancing game is an effective way to treat poststroke balance dysfunction.
