Abstract?AlM: To study the number of myogenin - positive activated satellite cells in the inferior oblique muscles and the medial muscles of V- pattern exotropia with inferior oblique overaction, to further explore the possible etiological factors of V-pattern exotropia with inferior oblique overaction.? METHODS: The inferior oblique muscles and the medial muscles were cut from V - pattern exotropia patients with inferior oblique overaction during strabismus operation treated as the strabismus group. Cross sections were stained immunohistochemically for the presence of activated satellite cells, as identified by myogenin immunoreactivity. The inferior oblique muscles and the medial muscles were obtained from the corneal transplant donors ( six eyes of six cases) , which treated as the control group.? RESULTS: The frequency of myogenin - positive satellite cells of the inferior oblique muscles was (22. 7± 7.03)% and (4. 2±0. 75)% in the strabismus group and the control group. Significant differences existed in the expression of myogenin in two groups (P<0. 05). Again, the frequency of myogenin-positive satellite cells of the medial muscles was (2. 2±0. 75)% and (4. 5±1. 05)% in the strabismus group and the control group. Significant differences also existed in the expression of myogenin in two groups (P<0. 05).?CONCLUSlON: lt is first report that myogenin-positive satellite cells presents in extraocular muscles of V -pattern exotropia with inferior oblique overaction. The current results suggest that myogenin is one of possible etiological factors of V-pattern exotropia with inferior oblique overaction.

Objective To investigate the concentration on clinical service of both medical workers and patients,for the purposes of better quality of care and concentration of medical workers,and better mental feelings of the patients′ and doctor-patient relationship.Methods 1 000 medical workers and patients were sampled from 8 hospitals of four regions in Jiangsu province by stratified randomization for questionnaire survey.The purpose is to study the clinical concentration of medical workers in terms of interpretation,listening,emotion and empathy,and compare the differences between doctors and patients regarding clinical concentration.Results 48.5% of the medical workers and 44.8% of the patients said that medical workers would interrupt the patients within 2 minutes.Time constraints of clinical consultation contribute to poor disease information collection,medical explanation and informing.The investigation found the difference between doctors and patients in clinical concentration is significant statistically(χ2=104.329,P=0.000),while medical workers were unaware of their lack of concentration to patients.18.2% of the patients complained that medical workers could hardly or refuse to understand their feelings.Conclusions Medical workers are advised to respect their patients by offering total concentration on diagnosis and treatment;to respect their career with sufficient concentration on diagnosis and treatment;and to respect medical science to offer medical humanistic care.

Objective To study the clinical characteristics of intrauterine re-adhesions treated by transcervical resection of adhesion (TCRA). Methods Between January 2012 and January 2015, 12 patients with intrauterine re-adhesions after TCRA in other hospitals had fertility requirements , including 10 cases of severe intrauterine adhesions and 2 cases of moderate intrauterine adhesions .In our hospital , the 12 patients underwent laparoscopic exploration and TCRA .After operation the patients were treated with artificial cycle therapy for 3 months and then underwent hysteroscopic examination . Results In the operation, the remaining of 50%endometrium was found in 1 case, the remaining of 30%endometrium was found in 1 case, and the remaining of 20%endometrium in 9 cases.Only petechial and patchy residual endometrial islands were found in 1 case.Uterine dysplasia was found in 3 cases.Re-examinations of hysteroscopy 3 months after surgery showed 4 cases of uterine cavity normal recovery , 6 cases of moderate intrauterine adhesions, and 2 cases of mild intrauterine adhesions .Follow-up for 18-42 months (mean, 28.5 months) in the 12 cases showed 2 cases of term pregnancy and 1 case of spontaneous abortion .The other 9 patients had no pregnancy , 3 of which withdrew the treatment and 6 of which underwent further treatment . Conclusions Patients with intrauterine re-adhesions usually have seriously damaged endometrium and poor recovery .We suggest that TCRA should be completed by experienced professionals to reduce the residual endometrial destruction , so as to improve the treatment outcomes of intrauterine adhesions .

Metformin improves glycemic control mainly due to improved insulin sensitivity.Dipeptidyl peptidase-4(DPP-4) inhibitor,which suppresses degradation of glucagon-like peptide-1 (GLP-1) and maintains the bioactivity of endogenous GLP-1,improves islet dysfunction.Moreover,recent studies suggested that metformin enhanced the biological effect of GLP-1 via different mechanisms and that DPP-4 inhibitor enhanced insulin sensitivity in type 2 diabetes.Therefore,the combination therapy of DPP-4 inhibitor and metformin could simultaneously ameliorate the two major defects of type 2 diabetes and obtain complementary and synergistic benefits for glycemic control.

Objective To investigate the knowledge of osteoporosis and its related behavior in middle-aged and elderly people.Methods A total of 1199 residents aged≥45 years in Hangzhou community were investigated by health survey questionnaire of osteoporosis.Results There were statistically significant differences in osteoporosis symptom scores according to ages (aged 45 to 59 years,6.38±2.64; aged 60 to 74 years,5.69±2.83; aged over 75 years,4.43±2.54),and according to education background (middle school or below.4.56± 2.01; secondary school,6.07±2.45; university or higher,8.25±2.69),and according to occupation (mental labour,5.89±3.21;manual labour,4.57 ± 2.36),and residence (city,6.12 ± 3.32 ; countryside,4.34 ± 2.25) (F/t =14.59,26.94,6.29,8.35,respectively,P＜0.01).There were significant differences in types ofexercise between rural and urban population (no exercise or little exercise,30.4％ vs.32.9％; light burden movement,64.4％ vs.53.5％; weight-bearing exercise,5.2％ vs.13.6％; x2 =22.13,P＜0.01).The significant food intake differences were found between rural and urban residents (milk,30.2％ vs.38.3％ sea-food,28.2％ vs.35.7％; bean-products,48.3％ vs.56.1％; fruit,52.6％vs.62.5％; coffee,3.2％ vs.7.4％; x2=8.55,7.77,7.21,19.37,10.14,respectively,all P＜0.01).Conclusions Health education should be individualized based on age,education level and occupation.The elderly and low education groups should be concerned.We should shift the focus of publicity and education to the countryside and enhance the awareness of osteoporosis prevention in order to build a healthy lifestyle.

Objective To investigate the expression of PES1 in ovarian cancer and its relationship with the vascular endothelial growth factor(VEGF) expression .Methods The expression of PES1 in ovarian cancer tissues and corresponding pericancerous tis-sues was detected with Western blot .Results The expression of PES1 in ovarian cancer tissues was obviously higher than that in the pericancerous tissues .The secretion amounts of VEGF in cell culture fluid of CAOV-3 and ES-2 with transfection of FLAG-PES1 were elevated from (178 .0 ± 11 .8) pg/mL and (309 .5 ± 18 .5) pg/mL to (375 .0 ± 18 .3) pg/mL and (633 .2 ± 25 .7)pg/mL respectively (P<0 .01) ,the secretion amounts of VEGF were also increased(P<0 .01) .The relative VEGF mRNA levels were also raised by 1 .8 times and 2 times respectively (P< 0 .01);Western blot simultaneously showed that the over expression of PES1 could increase the expression of HIF-1αin these two kinds of cells .The luciferase report gene transcriptional activation activity de-tection reveald that PES1 had no direct effect on the VEGF transcription .After cotransfecting HIF-1αSiRNA and FLAG-PES1 to CAOV-3 and ES-2 cells ,Western blot demonstrated that HIF-1αSiRNA could obviously inhibit the increase of HIF-1αexpression induced by PES1 ,at the same time the secretion amounts of VEGF and mRNA level were also supressed .Conclusion The expres-sion of PES1 is obviously up-regulated in ovarian cancer tissues .
