China Pharmacist 2017;20(3):506-508
Objective:To observe the clinical efficacy of Pingxiao capsules in the treatment of benign thyroid nodules. Methods:Totally 240 patients with benign thyroid nodules were randomly divided into the treatment group and the control group with 120 ones in each. The control group received levothyroxine at low dose, the treatment group received Pingxiao capsules, and the treatment course was 3 months. The type B ultrasonic inspection and lab inspection ( for thyroid hormones and blood lipid) were carried out, the cura-tive effect was compared and the adverse reactions were recorded as well. Results:Three patients in the treatment group and five ones in the control group were lost during the follow-up. After the treatment, the max diameter of thyroid nodule and the thyroid volume de-creased in both groups (P<0. 05), and those in the treatment group were smaller than those in the control group (P<0. 05). The levels of TSH and TC in the control group decreased after the treatment, which were significantly lower than those in the treatment group (P<0. 05). The total effective rate in the treatment group was higher than that in the control group, and the incidence of ad-verse reactions was lower than that in the control group, and both had significant differences between the groups (P<0. 05). Conclu-sion:Pingxiao capsules are effective and safe in the treatment of benign thyroid nodules.

Objective To investigate the biological effects of Wnt gene in kidney cancer Caki?2 cells. Methods The Wnt gene was silenced in kidney cancer Caki?2 cells by lentivirus vector. The cell proliferate ability of cells in each group were assayed by CCK?8 kit at different time points. The apoptosis of Caki?2 cells was observed after silencing Wnt gene by transmission electron microscope. The invasion ability of each group cells was tested using Transwell chambers. The genes expression changes of Wnt/β?catenin signaling pathway and apoptosis related gene were determined by realtime PCR. Results Compared with the other two groups,the cell proliferate ability of the cells after silencing Wntgene was suppressed,and the difference was statistically significant(P<0.05). Apoptosis increased significantly in shRNA+Caki?2+Wnt group cells with silencing of Wntgene, and apoptotic body appeared in these cells. In invasive experiment,the number of emigrated cells in shRNA+Caki?2+Wnt group were significantly lower than other groups(P<0.05). The expression of Wnt mRNA,β?catenin mRNA and Bcl?2 mRNA in shRNA+Caki?2+Wnt group cells was lower than other groups(P<0.05). Conclusion Silencing of Wnt gene of kidney cancer Caki?2 cells can affect the proliferation rate of the cells, promote the cell apoptosis,and inhibit the invasion ability,which provide certain theoretical basis for the research and development of new drugs and new therapeutic targets.

Journal of China Medical University 2019;48(1):48-52
Objective To evaluate the clinical efficacy of laparoscopic radical hysterectomy and pelvic lymph node dissection (PLND) in cervical squamous cell carcinoma (CSCC). Methods The clinical data of 83 CSCC patients in our hospital were retrospectively analyzed. The open surgery group (n = 43) underwent traditional transabdominal radical hysterectomy and PLND, while the laparoscopy group (n = 40) underwent laparoscopic radical hysterectomy and PLND. Intraoperative and postoperative indices were compared between the two groups. Results The intraoperative bleeding volume in stage ⅠB1 and ⅡAl patients in the open surgery group was greater than in the laparoscopy group. The operative duration was shorter and fewer lymph nodes were dissected in the open surgery group than in the laparoscopy group (P < 0.05). The time to flatus, fever duration, and hospital stay in stage ⅠB1 and ⅡA1 patients in the open surgery group were longer than in the laparoscopy group (P < 0.05). The frequency of painkiller use in stage ⅡA1 patients in the open surgery group was greater than in the laparoscopy group (P < 0.05). There was no statistical difference in the incidence of intraoperative and postoperative complications between the ⅠB1 and ⅡA1 groups (P> 0.05). The physical fitness and social function scores and the adverse effects were significantly different in the open surgery group from those in the laparoscopy group (P < 0.05). Conclusion Laparoscopic radical hysterectomy and PLND for CSCC can reduce intraoperative bleeding volume, increase the number of lymph nodes dissected, shorten the fever duration and hospital stay, and increase the quality of life.

OBJECTIVETo study the efficacy and explore the mechanism of the anti-tumor immunity elicited by heat shock protein 70-peptide complexes (HSP70-PC) derived from tumor cells.
METHODSCells culture, flow cytometric analysis, affinity chromatography for protein purification, SDS-PAGE, Western-blotting and animal experiment were used.
RESULTSHSP70-PC immunization rendered protective effect to both naive tumorl-bearing mice. All of the naive mice obtained complete resistance to Hcaf cell attack; 40% of the tumor-bearing mice survived for over 90 days, whereas the mice of control group died within 2 weeks (P < 0.01). CD8+ subset of T lymphocytes in the peripheral blood of immunized mice increased by 12%.
CONCLUSIONHSP70-PC induces anti-tumor immunity via activation of cytotoxic T lymphocytes (CTLs), and it possesses strong tumor vaccine effect. Our research adds more evidence to support the clinical use of HSP70-PC to fight human cancers.
