Diabetes mellitus is a worldwide disease and a growing public health burden.Female sexual function in patients with diabetes mellitus is complex and encompasses physical and emotional well-being across the lifespan.This review aims to discuss the development of sexual dysfunction in women with diabetes,while defining the parameters of dysfunction,and to present suggested risk factors and pathogenetic pathways,while offering evidencebased strategies for the evaluation of sexual dysfunction and management.

University of Manchester who first introduced Problem based learning(PBL)to the UK medical education,and adopted this new curriculum in 1994.Notably,Cambridge and Oxford have always had a high proportion of student-centred and self-directed learning,and have therefore not introduced PBL.Other medical schools have followed the example of Manchester,now PBL has become the mainstream curriculum in British medical edacation.First,this article is going to introduce how PBL curriculum is structured at Manchester medical school,and then reflect and give some thoughts on its current practice.

Objective To evaluate the tolerance of preoperative neoadjuvant chemoradiotherapy (neoCRT) plus esophagectomy, as well as the short-term outcome, tumor resection rate, incidence of postoperative complications, and perioperative mortality, in patients with locally advanced esophageal cancer.Methods This study included 74 patients with thoracic esophageal cancer who were admitted to our hospital from May 2011 to June 2015.Chemotherapy and radiotherapy were performed concurrently.The chemotherapy consisted of vinorelbine (25 mg/m2 on days 1, 8, 22, and 29) and cisplatin (25 mg/m2 on days 1-4 and 22-25).The radiotherapy was conventionally fractionated with a total dose of 40 Gy (2.0 Gy/d).At 4-8 weeks after chemoradiotherapy, esophagectomy was performed (neoCRT+surgery group);definitive chemoradiotherapy (DCRT) was performed in the patients who refused surgery (DCRT group);follow-up was performed in the patients who refused any anti-cancer therapies after neoCRT (neoCRT group).Results Forty-four patients underwent neoCRT+surgery, with a radical resection (R0) rate of 100% and a pathological complete response (pCR) rate of 43%;17 patients received DCRT;13 patients received neoCRT alone.For the neoCRT+surgery group, DCRT group, and neoCRT group, the 2-year overall survival (OS) rates were 79%, 75%, and 17%, respectively, and the 2-year disease-free survival (DSF) rates were 75%, 55%, and 17%, respectively.There were significant differences in OS between the neoCRT group and the neoCRT+surgery group (P=0.000) and between the neoCRT group and the DCRT group (P=0.001), but no significant difference was observed between the neoCRT+surgery group and the DCRT group (P=0.415).There were significant differences in DFS between the neoCRT group and the neoCRT+surgery group (P=0.000) and between the neoCRT group and the DCRT group (P=0.002), but no significant difference was observed between the neoCRT+surgery group and the DCRT group (P=0.416).The rate of clinical response to preoperative neoCRT was 87% for all patients.Fifty-six patients (76%) developed grade ≥3 myelosuppression due to preoperative neoCRT.The incidence rates of postoperative pulmonary infection, anastomotic leakage, and anastomotic stenosis were 21%, 12%, and 7%, respectively, and the perioperative mortality rate was 2%.Conclusions For patients with locally advanced esophageal cancer, preoperative neoCRT plus surgery can increase the clinical response rate and pCR rate, reduce the tumor stage, and improve the survival, but chemoradiotherapy toxicities and perioperative complications cannot be ignored.

Lian Qiao Bai Du Wan was used to study the identification of Chinese patent medicine by molecular marker technique. DNA was extracted through modified CTAB method. The psbA-trnH and rbcL sequences were gradient amplified, and PCR products were ligated with the pEASY-T5 vector and then transformed into Trans1-T1 cells, respectively. Clones were selected randomly and sequenced. All sequences were analyzed by BlastN and the neighbor-joining (NJ) phylogenetic tree was constructed by MEGA 4.0. The results showed that nine kinds of medicinal materials can be identified by psbA-trnH sequences, and six kinds of medicinal materials by rbcL sequences from Lian Qiao Bai Du Wan. Molecular marker technique can stably and accurately distinguish multi-origin medicinal materials in Chinese patent medicine.

Objective To investigate the expression of integrin β3 and osteopontin(OPN) in eutopic and ectopic endometrium of adenomyosis. Methods From January 2007 to July 2008, the endometrium specimens were collected from 43 patients with adenomyosis undergoing hysterectomy in Peking University First Hospital. Eutopic endometrium were 11 in proliferative phase and 32 in secretory phase (18 cases in mid-secretory phase) were collected. Ectopic endometriums were also collected. In the mean time, it was chosen 41 cases with pure subserous uterine myoma or cervical intraepithelial neoplasia (CIN) Ⅱ-Ⅲ treated by hysterectomy as controls including 12 endometrium in proliferative phase and 29 endometrium in secretory phase (19 cases in mid-secretory phase). The expression of Integrin β3 subunit and OPN in the endometrium were assessed by immunohistochemical staining and quantitative real-time polymerase chain reaction. Results (1)Immunohistochemical staining showed that positive staining of integrin β3 and OPN were present predominantly in eutopic and ectopic endometrial glandular epithelium. There was significant different protein expression of integrin β3 and OPN, which were 1.6±0.8 and 1.7±0.7 in eutopic endometrium,1.7±0.7 and 1.8±0.9 in ectopic endometrium,2.1±0.9 and 2.0±0.9 in control endometrium (P<0.05). The protein expression of integrin β3 and OPN in eutopic endometrium of adenomyosis in the proliferative phase(0.8±0.4 and 0.7±0.3) were remarkably lower than those of the secretory phase(1.8±0.8 and 1.9±0.8,P<0.01). The protein expression of integrin β3 and OPN in the endometrium of controls in the proliferative phase(1.0±0.4 and 1.0±0.4) were significantly lower than those of the secretory phase(2.5±0.7 and 2.5±0.7)(P=0.000). In the mid-secretory phase, the protein expression of integrin β3(2.0±0.9) and OPN (2.1±0.8)in eutopic endometrium of adenomyosis were significantly lower than that of control endometrium(2.7±0.5 and 2.7±0.7)(P<0.01). (2)The mRNA expression level of integrin β and OPN in eutopic and ectopic endometrium were assessed by quantitative real-time PCR(result was shown by median index). It was observed that integrin β3 mRNA and OPN mRNA were significantly lower in the eutopic endometrium of adenomyosis (4.69 and 4.23), when compared with ectopic endometrium(7.96 and 14.84)and controls (13.47 and 17.40) (P<0.05). Eutopic endometrium had higher mRNA expression of integrin β and OPN mRNA in the secretory phase (5.54 and 11.40) than that in the proliferative phase(2.69 and 3.30) (P<0.01).The mRNA expression level of integrin β and OPN of control endometrium in the proliferative phase (3.12 and 4.75)were significantly lower than that in the secretory phase(19.94 and 21.00, P=0.000). The mRNA expression of integrin β and OPN were 10.10 and 14.34 in the mid-secretory phase, which were significantly lower than 21.50 and 24.18 in control endometrium(P<0.05). Conclusions High expression of integrin β3 and OPN in ectopic endometrium of adenomyosis may cause endometriotic lesions; abnormal expression of integrin β3 and OPN in the endometrium of adenomyosis during the implantation window may contribute to infertility in some patients.

In this paper, Liuwei Dihuang pill was used to study the identification of Chinese patent medicine by fluorescence sequencing typing technology. The DNA of Paeonia suffruticosa was used as template to amplify by five pair of FAM fluorescence labeling primers. Then, the amplified products were sequenced. The sequencing results were analyzed by GeneMarker V1.80 to screen the best fluorescence labeling primers. As a result, psbA-trnH fluorescence labeling primer was used to identify the raw materials of Liuwei Dihuang pill. The results showed that three kinds of raw plant medicinal materials in Liuwei Dihuang pill were able to be correctly identified by psbA-trnH fluorescence labeling primer. The fluorescence sequencing typing technology can stably and accurately distinguish raw medicinal materials in Chinese patent medicine.
