Background and purpose:The traditional 3 incision surgery is an important means of esophageal cancer treatment, however, accompanied by more postoperative complications and higher mortality. Minimally invasive esophagectomy is a prospective technology with advantages, such as little trauma and quick recovery. This study retrospectively analyzed the perioperative effect of the esophagus cancer patients who accepted thoracoscopic-laparoscopic esophagectomy (TLE), open-laparoscopic esophagectomy (OLE) and open esophagectomy (OE) from Jan. 2013 to Jan. 2015. Methods:In this study, 72 patients received TLE, 76 patients received OLE and 115 patients received OE, respectively. One-way ANOVA, Kruskal Wallis test and Chi-square test were used to compare the differences of general clinical data, perioperative recover index, the number of lymphadenectomy and the postoperative complication among TLE, OLE and OE. Results:There were differences in the area of operative blood loss, duration of ICU stay and first standing time among the 3 groups. Pairwise comparison demonstrated that TLE group was signiifcantly better than OE group (P<0.012 5). The total number of lymphadenectomy among the 3 groups had no differences. However, the number of lymph node of the upper esophagus in the TLE groups was more than those in OLE group and OE group (P<0.001). The laryngeal recurrent nerve injury incidence in TLE group was signiifcantly higher than those in OLE group and OE group (P=0.012, 0.003). The total surgical complication had no differences among 3 groups. In areas of the cardiorespiratory system severe complication, 3 groups had statistical differences. Pairwise comparison showed TLE group was significantly less than OLE and OE group (P<0.0125). The first day and third day incidences of SIRS rate in TLE group were less than those in OLE group and OE group (P<0.0125). Conclusion:Comparing to OE group, with the same safety and feasibility, TLE had more advantages such as trauma, quick recovery, less complications. With the same effect of total lymphadenectomy to OE, TLE had the more advantage in upper mediastinal and recurrent laryngeal nerve lymph node cleaning.

[Objective] To compare the effects of Radix Astragali (RA) and triperygium glucosides (TG) on glomerular mesangial cells (GMC) proliferation and interleukin-6 (IL-6) secretion. [Methods] GMC were cultured with in-vitro cell culture technology. Serum containing RA and serum containing TG were prepared with serum pharmacological methods. GMC proliferation was detected by methylthiazolyltetrazolium (MTT) assay and IL-6 level by enzyme-linked immunosorbent assay (ELISA) to evaluate the effect of low-, moderate- and high-dosages of RA-containing serum and TG-containing serum under the condition of GMC over-proliferation. [ Results] Different dosages of RA-containing serum and TG-containing serum inhibited GMC proliferation and IL-6 secretion in a dose-effect manner, and the inhibitory effect of high- and moderate-dosage TG and high-dosage RA was stronger. [Conclusion] Under the condition of in-vitro GMC over-proliferation, RA has the similar inhibitory effects on GMC proliferation and IL-6 secretion with TG. The combined treatment of RA and TG can reduce the dose of TG and probably has an action in increasing effect and reducing toxicity.

The growth and development of plant is affected by environmental factors that include light,temperature and water. Many cis-elements that are response to these elicitors interact with transcription factors, and regulate the expression of target genes. It concludes by pointing out recent studies of cis-elements and transcription factors in the plant environmental response promoters, such as light, temperature and water inducible promoter. The molecular mechanisms of gene expression regulated by environmental factors was discussed. This is important to study the mechanisms that plant adapt the environment.

Objective To observe the expression of Bcl-2,Bax and proliferating cell nuclear antigen(PCNA) in liver of rats with hepatic fibrosis and the effects of transforming growth factor (TGF)-?1 vaccine on them.Methods Thirty healthy male Sprague-Dawley rats were assigned into 3 groups,named healthy control group(n=10),hepatic fibrosis group(n=10) and TGF-?1 vaccine treated group(n=10).The animal model with hepatic fibrosis was established by injecting solution dimethylnitrosamine (DMN) into abdominal cavity with concentration as 0.5% and dose as 0.2 mL/ 100 g.In TGF-?1 vaccine treated group,every rat was not only injected with DMN but also 150?g TGF-?1 vaccine protein.On the 42nd day,all rats were sacrificed.Then the blood and the liver tis- sues were collected.The expression levels of Bcl-2,Bax and PCNA in liver tissues were detected by S -P immunohistochemistry and observed by routine pathological evaluation.Alanine aminotransferase (ALT),aspartate aminotransferase(AST) and albumin(Alb) were determined by auto biochemical analytical tool.Serum levels of hyaluronic acid (HA),laminin(LN) were detected by radioimmunoas- say (RIA).Results The expression of Bax,which promoted apoptosis,directly correlated with pathological grade in liver of rats,while the expression of Bcl-2 and Bcl-2/Bax,which protected a gainst apoptosis,inversely correlated with pathological grade in liver of rats.The expression levels of TGF-?1 and Bax in healthy control group were significantly lower than those of fibrosis group,how ever,the expression levels of Bcl-2 were comparable between these two groups.As compared with fi- brosis group,the expression of TGF-?1 was significantly lower while the expression of Bcl-2 was sig nificantly higher in TGF-?1 vaccine treated group.However,the expression of Bax was comparable between these two groups.The expression level of PCNA of fibrosis group was significantly higher than that of healthy control group but dramatically lower than that of TGF-?1 vaccine treated group (Both P

Objective To study the clinicopathologieal features and expression of cyclin D1 and p53 in epithelial ovarian tumors,and to investigate the correlation between pathogenesis of ovarian cancer and epithelial borderline tumors.Methods Fifty four cases of ovarian borderline tumors and 45 cases of ovarian carcinomas from the People's Hospital,Peking University were reviewed retrospectively.The clinical data and pathological findings were analyzed.Immunohistochemical study of cyclin D1 and p53 was performed in all 99 cases.Results(1)In borderline tumors,the age of patients ranged from 14-82 (mean age=42.5)years.International Federation of Gynecology and Obstetrics(FIGO)stage of borderline tumors was stage Ⅰ in 48 cases,stage Ⅱ in 3 cases,and stage Ⅲ in 3 cases.In ovarian carcinomas,the age of patients ranged from 26-80(mean age=53.5)years.FIGO stage of carcinoma was stage Ⅰ in 6 cases, stage Ⅱ in 8 cases,stage Ⅲ in 26 cases,and stage Ⅳ in 5 cases.In follow-up of 54 cases with borderline tumors the 5-year survival rate was 98% and of 45 cases with carcinomas a 5-year survival rate of 51% was noted.(2)In 54 cases of borderline tumors,mucinous types accounted for 56%(30/54)and serous types accounted for 30%(16/54).There were 5 cases with micropapillary pattern,3 cases with peritoneal implants,3 cases with lymph node involvement,6 cases with microinvasion,one case with intraepithelial carcinoma,and one case with mural nodules.In 45 cases of carcinomas,serous carcinoma was the most (49%,22/45).The remainder included 3 cases of mucinous types,8 cases of endometrioid types,6 cases of transitional cell types,3 cases of mixed phenotype and 3 cases of undifferentiated types.(3) Overexpression of cyclin D1 and p53 was observed in 31%(14/45)and 56%(25/45)of ovarian carcinomas, respectively.There was a significant association between p53 overexpression and tumor grade.In the borderline tumor group,69%(37/54)had overexpression of cyelin D1 and 6%(3/54)had overexpression of p53.There were significant differences in expression of cyclin D1 and p53 between conventional serous borderline tumors and high-grade serous carcinomas(cyclin D1:91% vs 26%;p53:0 vs 58%).However, micropapillary serous borderline tumors and low-grade serous carcinomas showed remarkably similar expression of cyelin D1 and p53.Conclusions Epithelial ovarian borderline tumors are distinct from ovarian cancer in clinical progress and prognosis,and histological types.Overexpression of cyclin D1 is common in ovarian borderline tumors and low grade carcinomas.And overexpression of p53 is more common in high grade ovarian carcinomas.Conventional serous borderline tumors are distinct from high-grade serous carcinomas in pathogenesis.Micropapillary serous borderline ovarian tumors may be closely related to low grade serous carcinomas.

Objective To establish a time resolved fluoroimmunoassay (TRFIA) method for detecting Glypican 3 (GPC3) and to explore the diagnostic value of serum GPC3 for hepatic carcinoma (HCC). Methods Microplate coated with anti-GPC3 monoclonal antibody 7C8 and GP9 labeled with Eu3+ were used to establish TRFIA kit. The serum concentrations of GPC3 in 41 HCC patients and 44 chronic hepatitis (CH) patients were quantitatively analyzed. AFP was detected by with lowest limit of 2.06 μg/L. The CV of inter and intra assay were 12.25% and 12.91%, respectively. The average serum concentration of GPC3 in HCC patients was (86.68±110.39) μg/L (median: 56.98 μg/L). But in CH patients it was only (14.77±29.48) μg/L, which was significantly lower than that in HCC (Wilcoxon W=1335.00, Z=-4.99, P<0.001). With diagnostic cut-off value set at 42.94 μg/L, the diagnostic sensitivity and specificity of TRFIA GPC3 for HCC were 58.5% (24/41) and 95.5%(42/44) respectively. The diagnostic sensitivity of AFP was 46.3% (19/41) in 41 HCC patients, and was raised to 78.0% (32/41) when combined with GPC3. Conclusions Serum GPC3 assay by TRFIA is established and it could increase the diagnostic sensitivity for HCC when combined with AFP.
