Objective: To elucidate effects of mammalian sterile 20-like kinase 1 (MST1) gene on cell proliferation and apoptosis of human breast carcinoma cell line MCF-7. Methods: This study constructed plasmid pCMV-FLAG-MST1 and transfected it into human breast carcinoma cell line MCF-7 via mediation by Lipofectamine 2000. We detected the efficiency of transfection by Western blotting. The effect of MST1 on cell proliferation was measured by MTT assay at 12, 24, 36, and 48 h after transfection. The effect of MST1 on cell proliferation was also determined by BrdU incorporation assay at 36 h after transfection. Cisplatin was added into cultured cells at 36 h to induce apoptosis. Forteen hours later cell apoptosis was detected by Annexin V staining. Results: This study successfully constructed plasmid pCMV-FLAG-MST1. The MTT and BrdU incorporation assay showed that the cell proliferation was significantly inhibited after transfection of pCMV-FLAG-MST1. Annexin V staining demonstrated that cell apoptotic rate was relatively higher after overexpression of MST1. Conclusion: In summary, overexpression of MST1 decreases cell proliferation and induced apoptosis of human breast carcinoma cell line MCF-7.

Objective:To evaluate three-stage induced membrane technique combined with anterior and posterior double-plate fixation in the treatment of a total talus defect after infection.Methods:Included in this study were 11 patients with talus infection who had been treated at Department of Orthopaedics, Foshan Hospital of Traditional Chinese Medicine from January 2014 to December 2018. They were 8 males and 3 females, aged from 23 to 63 years (mean, 37.0 years). The infection followed re-implantation after open dislocation of total talus in 4 cases, internal fixation for open talus fracture of Gustilo type Ⅲa in 3 cases and surgery of open ankle fracture of Gustilo type Ⅲc in 2 cases, and was complicated with ankle intraarticular tuberculosis in 2 cases. The three-stage operations consisted of debridement, total talus resection, implantation of antibiotic bone cement and vacuum sealing drainage at the first stage, change of bone cement, re-debridement, wound closure or flap covering at the second stage 7 to 10 days later, and reconstruction after infection control using anterior and posterior double-plate fixation and induced membrane technique at the third stage 6 to 12 weeks later. Assessment of lower limb shortening was performed by comparing the full length of the leg between the normal and affected sides; the functions were assessed by comparing the ankle-hindfoot scores of American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) between preoperation and the final follow-up.Results:The 11 patients were followed up for an average of 24.3 months (from 12.2 to 37.5 months). Superficial skin necrosis was observed in 2 patients and injury to superficial peroneal nerve in one. Absolute calcification of the autograft area was observed in all patients, leading to ankle fusion. The final follow-ups observed no significant difference in the full length of the leg between the normal and affected sides [(380.4±35.5) mm versus (376.3±32.8) mm] ( P>0.05) , a significant increase in the ankle-hindfoot AOFAS scores from preoperative 28.0±3.4 to 72.8±5.4, and a significant decrease in VAS scores from preoperative 5(5,6) to 0(0,1) (all P<0.05). Slight varus developed in 2 patients and slight ankle stiffness in 3; recurrence of infection or breakage of implants was found in none of the patients. Conclusion:Three-stage induced membrane technique combined with anterior and posterior double-plate fixation can effectively control infection of the talus, maintain the length and reconstruct the function of the lower limb after a total talus defect.

To observe the preventive effect of polydatin on diabetic myocardial hypertrophy in mice and discuss its and mechanism. The diabetic model was induced with low dose STZ (40 mg x kg(-1) x d(-1) x 5 d, ip) for five days in mice. The myocardial hypertrophy was determined by hypertrophy indexes (LVHI, left ventricular/right ventricle and septum), left ventricular/body weight (LV/BW), the histological examination and the mRNA expression of atrial natriuretic factor(ANF). The fast blood glucose(FBG), serum insulin and plasma hemoglobin A1c ( HbA1c) levels were detected, and then HOMA insulin resistance index ( HOMA. IR) was calculated. The mRNA and protein expressions were measured by qRT-PCR and western blotting, respectively. According to the results, the FBG of the model group exceeded 11.1 mmol x L(-1), with notable decrease in BW and significant increase in insulin, HbA1c and HOME. IR, suggesting the successful establishment and stability of the diabetic model. The increases in LVHI, LV/BW, cell surface and ANF mRNA indicated a myocardial hypertrophy in diabetic mice. Meanwhile, the model group showed decrease in mRNA and protein expressions of PPARβ and significant increase in NF-κB p65, COX-2 and iNOS expressions. After the preventation with PD (50, 100 mg x kg(-1) x d(-1)), diabetic mice showed increase in BW, reduction in the levels of FBG, insulin and HbA1 c, relief in insulin resistance and significant recovery in hypertrophy indexes, indicating PD has the protective effect in diabetic myocardial hypertrophy. Meanwhile, PD up-regulated the expression of PPARβ, inhibited the expressions of NF-κB p65, COX-2 and iNOS, demonstrating that PD's protective effect may be related to the activation of PPARβ and the inhibition of NF-κB, COX-2 and iNOS signaling pathways.

Aim To investigate the effect of GW0742 on the endothelial dysfunction induced by high glucose
(glucose at 55 mmol · L -1 )in isolated rat thoracic aorta and its related mechanisms.Methods The end
othelium-dependent relaxation of acetylcholine was per-formed in the absence or presence of GW0742 at differ-ent concentrations under high glucose condition.The structure of aorta was observed by HE staining.Moreo-ver,the content of NO was also measured by nitrate re-duction method.The mRNA and protein expression were detected by quantitative real-time PCR and West-ern blot,respectively.Results Compared with the control group,acetylcholine-induced vasodilatation was impaired by high glucose.Meanwhile,the structures of endothelial cells and smooth muscle cells were also in-terrupted.Furthermore, the expressions of PPARβmRNA and protein reduced while the NF-κB p65 ex-pression increased significantly which occurred in par-
allel with decreasing eNOS expression and NO concen-tration (P <0.01 ).GW0742 (0.01 ,0.1 ,1 μmol· L -1 )restored the relaxation of acetylcholine in a dose-dependent manner,and reversed the mRNA and pro-tein expression of PPARβ,NF-κB p65 and eNOS,as well as NO content (P <0.01 ).Conclusion GW0742 attenuates the injury of endothelial dysfunc-tion induced by high glucose,which may be,at least partly,mediated by the up-regulation of PPARβ,then the down-regulation of NF-κB,and the activation of eNOS-NO signal pathway.

Objective To detect and type herpes simplex virus (HSV) in genital lesions of the patients attending STD clinic. Methods Clinical data were collected and analyzed from patients with anogenital non-herpetic lesions including induration or furuncle, fissure, folliculitis, single ulcer and so on. HSV was detected and typed by culture and PCR with specimens taken from these lesions. Results One hundred and five cases were recruited in this study. Among them, 18 cases presented induration (furuncle), 15 fissure, 16 folliculitis, 7 abrasion, 12 single ulcer, 25 nonspecific erythema and 12 balanoposthitis with edema and exudation. HSV was found in 33.3%(6/18), 20%(3/15), 37.5%(6/16), 28.6%(2/7), 33.3%(4/12), 20%(5/25) and 50%(6/12) of these lesions, repectively, by PCR, while in 22.2%(4/18), 13.3%(2/15), 25%(4/16), 14.3%(1/7), 33.3%(4/12), 8%(2/25) and 41.7%(5/12), repectively, by viral culture. The positive rates of HSV from all these non-herpetic lesions were 30.5% (32/105) and 21% (22/105), respectively (? = 0.095, P = 0.114), by PCR and viral culture. The results of HSV typing were consistent between PCR and immunofluorescence with type-specific monoclonal antibodies. Among those with HSV infections, HSV-1 infection acounted for 9.4% (3/32), and HSV-2 90.6% (29/32). Conclusions The clinical manifestations of genital HSV infections vary, and HSV could be isolated from lesions of induration (furuncle), fissure, folliculitis, abrasion, single ulcer, nonspecific erythema and balanoposthitis with edema and exudation. HSV-2 is the predominant type.

Objective To evaluate the expression of human kallikrein10 (KLK10) in different endometrioid tissues and analyse the relationship of KLK10 with ER and PR in endometrioid adenoearcinoma.Methods The expression of KLK10 protein in 12 normal endometria,19 endometrial hyperplasia and 34 endometrial carcinoma were detected by immunohistochemistry.The correlations of the expression of KLK10 protein,ER and PR were analyzed.Results The expression of KLK10 in stage Ⅰ,Ⅱ and Ⅲ were 64.3 ％(9/14),30.0 ％ (3/10),10.0 ％ (1/10),and the difference was statistically significant (P ＜ 0.05).The expression of KLK10 in endometrial carcinoma,normal endometria,endometrial hyperplasia were 66.7 ％ (8/12),33.3 ％(4/12),10.0 ％ (1/10),and the difference was statistically significant (P ＜ 0.05).The expression of KLK10 in G1,G2,G3 were 66.7 ％,33.3 ％,10.0 ％,and the difference was statistically significant (P ＜ 0.05).The positive rate of KLK10 expression was 38.2 ％ and the positive rates of ER and PR expression were 67.6 ％and 55.9 ％,respectively,in 34 endometrial carcinoma.The expression of KLK10 was positively correlated with ER and PR expression (x2 =0.448,P ＜ 0.01).Conclusion Absence or down-regulated expression of KLK10 may play an important role in the formation and development of endometrioid adenocarcinoma.The low expression of KLK10 is correlated with low expression of ER and PR in endometrioid adenocarcinoma.The positive expression of KLK00,ER and PR predicts a better prognosis.

The influence of medium variety、thermal treatment of the soil samples and inhibitor to the isolation effect of actinomycetes was studied by plate paint isolation methods.The results showed that: ①The isolation results of gauze No.1(GA) and straw decay substance agar(SDSA) might reflect basic station of soil actinomycetes. ②Thermal treatment (120℃?1.0h)in soils might promote actinomycetes spore sprouting and increase the quantity and variety of actinomycetes. The quantity and varieties of actinomycetes in the Soils that were treated with 120℃?1.0h were increased by 5.5%～54.9% and 12.5%～100% than the check of none-thermal treatment respectively. But thermal treatment had no effect on reduce the quantity of bacteria. ③The quantity of bacteria had significant reduction by adding 75?g/mL K 2Cr 2O 7 and 1～3?g/mL penicillin at same time to the isolation medium, and had little effect on the quantity and varieties of actinomycetes. Actinomycetes quantity (?10 6cfu/g) and variety of the treating of 75?g/mL K 2Cr 2O 7 and 1～3?g/mL penicillin in No.1 soil on SDSA medium had reductions by 0～58.8% and 0～18.2% compared with treating of 75?g/mL K 2Cr 2O 7, respectively. ④streptomycin might not been used for bacterteria inhabitor in the isolation of actinomycetes.
