Template direct dye-terminator incorporation with fluorescence-polarization (TDI-FP assay) is a technology for genotyping single nucleotide polymorphisms (SNPs). To apply this method in analyses of A647G variation in human papillomavirus (HPV) 16 E7 gene from HPV 16-positive cervical tissues, a total of 91 and 49 HPV 16-positive DNA samples obtained from women with cervical cancer and normal/inflamed cervices living in Shaanxi in northwest China were subjected to the partial E7 gene PCR with nucleotide (nt) 647 in the products. Then, the oligonucleotide probe designed to anneal immediately to nt 647 was hybridized to the template within the PCR amplicons, and extended specifically by TAMRA-ddTTP or R110-ddCTP directed by the base at nt 647. The increasing FP values were read and the base at nt 647 was identified. The prevalence of nt 647 A→G was 35.71% (50/140). The variation 647G detected in 42.86% (39/91) of women with cervical cancer was significantly higher than 22.45% (11/49) detected in those with normal/inflamed cervices (x2 = 5.778, P = 0.016). The odds ratio (OR) between these two groups was 2.59 (95% confidence interval=l.17~5.71). The results demonstrate that TDI-FP method can be potentially applied in analysis of interest point mutations in HPVs. The incidence and risk implication of HPV 16 A647G variant infection in Shaanxi, China, displays significant geographic difference from other areas. The HPV 16 with E7 gene A647G point mutation appears to have a higher risk for invasive cervical cancer in women living in Shaanxi.

Objective To investigate the expression and significance of p53 and CDK4 proteins in human endometrial adenocarcinoma. Methods Expressions of p53 and CDK4 proteins were detected by immunohistochemical technique in 32 cases of endometrial adenocarcinoma. Results The positive expression rate of p53 protein in the 32 cases of endometrial adenocarcinoma was 43.8% (14/32), and the positive rate of p53 in endometrial adenocarcinoma was negatively related to pathological grade, myometrial invasion and lymph node metastasis (P 0.05). The positive expression rate of CDK4 was 68.8% (22/32), and CDK4 expression was significantly associated with myometrial invasion and lymph node metastasis (P 0.05) . There was negative correlation between p53 and CDK4 (P

OBJECTIVETo compare the perioperative complications between Ivor-Lewis approach and McKeown approach in minimally invasive esophagectomy and gastric tube reconstruction for the treatment of middle and lower thoracic esophageal cancer.
METHODSRetrospective analysis of clinical data was performed on 288 patients with middle and lower thoracic esophageal cancer who underwent completely minimally invasive esophagectomy by one surgical team in Fujian Medical University Union Hospital from December 2010 to March 2014. Among the 288 patients, 103 patients underwent combined laparoscopic and thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis using a transoral anvil(Orvil)(Ivor-Lewis group, 2-incision) and 185 patients underwent combined laparoscopic and thoracoscopic esophagectomy and cervical anastomosis(McKeown group, 3-incision). Patients were stratified by surgical approach and perioperative outcomes were compared between the two groups.
RESULTSThere were no statistical differences between two groups in intra-operative blood loss, conversion to open, extubation time, time to resume oral intake, postoperative hospital stay, the median number of lymph nodes resected. The operation time of Ivor-Lewis group was significantly shorter than that of McKeown group [(283.4±32.0) min vs. (303.6±43.7) min, P=0.003). The hospital cost of Ivor-Lewis group was significantly higher than that of McKeown group [(76 492±18 553) yuan vs. (68 923±17 331) yuan, P<0.01]. There were no statistical differences between two groups in chylothorax, delayed gastric emptying, atrial fibrillation, postoperative bleeding, admission to ICU, short-term postoperative mortality (P>0.05). The total postoperative complication morbidity of Ivor-Lewis group was significantly lower than that of McKeown group(16.5% vs. 31.4%, P<0.01). Ivor-Lewis group had lower pulmonary complication(8.7% vs. 25.9%, P<0.01), anastomotic leakage(1.9% vs. 13.0%, P<0.01), anastomotic stricture (0% vs. 4.9%, P<0.05), recurrent laryngeal nerve injury(1.0% vs. 7.0%, P<0.05).
CONCLUSIONIvor-Lewis approach is associated with less postoperative complications, but higher cost as compared to McKeown approach in the treatment of middle and lower thoracic esophageal cancer.

The Master of Public Health (MPH) is one of the internationally recognized ways of training professionals in the medical and health field. With the outbreak of COVID-19 pandemic, the need for talents who can serve the national public health emergency management system has accelerated. This article makes the comparison of public health education in China and the UK, starting from the reasons and advantages of medical education in two countries, selecting several universities with high rankings in public health in China and the UK as the research objects, collecting and summarizing their programme descriptions, from the enrollment mode, training objectives, cultivation mode and degree types, curriculum settings, etc., in the MPH programme descriptions in order to find the advantages of MPH education in the UK, which can be used for reference in the education and training of public health talents in China, and is of great significance for the improvement and optimization of MPH education in China.
