OBJECTIVE:To observe the effects of single administration of carboplatin by different ways on drug accumulation concentration and treatment of tumor tissue before surgery. METHODS:60 patients with resectable advanced gastric cancer were randomly divided into intraperitoneal administration group(30 cases)and intravenous administration group(30 cases). All patients received 50 mg/m2 Carboplatin injection,intravenous administration,it stopped 4 weeks after continuous 5 d,repeated 3 times, when the last chemotherapy,intraperitoneal administration group was given 30 mg/m2 Carboplatin injection,adding into 750 ml 0.9% Sodium chloride injection,and placed in 37 ℃ water bath for preheating,taking paracentesis for disposable rapid injection. Intravenous administration group was 30 mg/m2 Carboplatin injection,adding into 750 ml 0.9%Sodium chloride injection,by intra-venous infusion within 30 min. Both groups were administered once for at least 1 week,then surgery was taken after 5 d. The car-boplatin accumulation concentration in 2 groups was determined after 160-180 min and 250-260 min,respectively,and the efficacy in the 5th day and incidence of adverse reactions during treatment were recorded. RESULTS:The total effective rate after 5 d,peri-toneal fluid,portal vein and peripheral blood after 160-180 min,and carboplatin accumulation concentration in cancer tissues,adja-cent normal tissues,peritoneum,omentum and negative lymph node after 250-260 min in intraperitoneal administration group were significantly higher than intravenous administration group,the incidence of adverse reactions was significantly lower than intrave-nous administration group,the differences were statistically significant(P<0.05). CONCLUSIONS:Compared with intravenous in-fusion,intraperitoneal injection of carboplatin before surgery can improve the local accumulation concentration and chemotherapeu-tic effect and reduce incidence of adverse reactions.

Objective: To investigate the safety and feasibility of Laparoscopic left hepatic lobe resection in the treatment of bile duct stones. Methods: Eighty cases in our hospital with bile duct stones for left hepatic lobectomy were randomly divided into control group and experimental group. The control group was received open left hepatic lobectomy. The experimental group was received laparoscopic left hepatic lobectomy. The operative time, incision length, blood loss, hospital stay, hospital costs and incidence of postoperative complications were compared of two groups. Results: The incision length and length of hospital stay of experimental group was significantly shorter than control group. The difference was statistically significant (t=4.46, t=5.38; P<0.05). While operative time, blood loss, hospital costs and postoperative complication rate of two groups showed no significant difference (t=0.32, t=0.73, t=0.37; x2=0.47; P>0.05). Conclusion:Laparoscopic left hepatic lobe resection is safe and feasible in the treatment of bile duct stones with the advantage of less trauma and quicker recovery. It’s worthy of clinical widely used.

Objective To explore the effects of different pressures of carbon dioxide pneumoperitoneum under laparoscopic surgery on IL-1β, IL-6, and TNF-α. Methods Ninety patients with ASA Ⅰor Ⅱwho were scheduled to elective operation under laparoscopic surgery from October 2010 to June 2012 were randomly divided into three groups .After endotracheal intubation , different carbon dioxide pressures , 10 mm Hg, 12 mm Hg, and 15 mm Hg, were orderly given to group 1, 2, and 3 to build pneumoperitoneum .The serum levels of IL-1β, IL-6, and TNF-α, as well as hemodynamic parameters , were assessed at the time after anesthesia ( T0 ) , after pneumoperitoneum development ( T1 ) , of position placement before operation ( T2 ) , after dismissing pneumoperitoneum (T3), and 24 hours after operation (T4), respectively. Results The measures of MAP, HR, and PETCO2 had no significant differences between each other of the three groups ( P >0.05), and the MAP and HR results showed significant differences among the three groups at different time points (P<0.05) whereas no difference for PETCO2 values (P>0.05).There were statistical significances between the three groups in levels of IL-1β, IL-6, and TNF-αat time points of T1 , T2 , T3 , and T4 , respectively (P<0.05).As compared with T0, there were significant differences in levels of IL-1βat the time points of T1 and T2 in the three groups (P<0.05).There were no significant differences in IL-6 levels between the group 1 and group 2 at every time points (P>0.05).In the group 3, the levels of IL-6 were significantly higher at time points of T 1, T2, and T3 than at T0(P<0.05).In the group 2 and group 3, the levels of TNF-αat T1, T2, and T3 were significantly different from at T0(P<0.05), whereas in the group 1, significant difference was seen only between the time points of T 0 and T1(P<0.05). Conclusion Low pneumoperitoneum pressure leads to minor stress effects .A 10 mm Hg carbon dioxide pneumoperitoneum is recommended .

In the recent years,many studies have confirmed that vascular endothelial progenitor cells(EPC)can migrate,proliferate and differentiate into mature endothelial cells.They participate in the angiogenesis not only during the process of embryonic development but also during the growth and metachoresis of tumor.Therefore,further studies on EPC are important for the understanding of the formation and treatment of tumor.This review summarizes the research progress in this field.

Human papillomavirus (HPV) is one of the most common infection of the virus in the reproductive tract,a growing number of studies found that HPV infection is closely related to female infertility.This paper mainly introduces the structure characteristics of HPV,the correlation of reproductive tract infection of HPV and infertility,the related factors of infertility by reproductive tract infection of HPV,the influence of early pregnancy and adverse pregnancy outcomes,the relationship with assisted reproductive technology,etc.

Berberine is the major component of Coptidis Rhizoma and it has been used as anti-infection, anti-inflammation drug for gastrointestinal diseases. In recent years, evidence showed that it could regulate glucose and lipid metabolism. Moreover, its activity had been tested by clinical trials and animal researches. The mechanisms of berberine in diabetes include: improving the function of beta-cell; prompting insulin secretion and islets regeneration, lowing lipid level, regulating glucose and lipid metabolic by influence transcriptional factors expression such as PPARgamma, C/EBPalpha, SREBP-1c, LXR, having the activities of anti-oxidation and inhibiting reductase to repress oxidative stress state and regulate metabolic signal pathway. Although numbers of data supported that berberine could improving insulin resistance by clinical trials and animal studies, the large scale, multicenter clinical trials are needed to evaluate the effects of berberine for diabetes and its complications in the time of evidence-based medicine.

With the standard of living improved, people had less and less interests in exercise, adiposity has being a problem that people have to be up against all over the world. Exercise can step up energy expenditure, decrease fat accumulation, minish the volume of fat cell, and is one of widely used, effective, safe, economical measures of anti-adiposity. The adaptable change of neuroendocrine system in exercise quicken up fat to burn more. Leptine is an important signal of measuring fat content of body. The relationship between adiposity and leptin, and the effect of exercise on leptin was reviewed in this paper.

Ginseng and its effective components are famous for their influence to enhance human immunity, regulate endocrine and antioxidant action. However, the different effects of different components are not clear. In this study, Wistar rats were used to study the effects of main components of ginseng, including total ginsenoside, panaxadiol saponins, panaxtrol saponin and ginseng polysaccharide. The results showed that the effects of panaxadiol saponins and ginseng polysaccharide on improving animal immune organ weight, plasma interleukin 2 (IL-2), interleukin 6 (IL-6), plasma gamma-interferon (IFN-γ), tumor necrosis factor alpha (TNF-α) were better than that of the other groups. Total ginsenoside and panaxtrol saponin can effectively increase the concentration of spleen NK cells (NKC) while panaxadiol saponins and ginseng polysaccharide can significantly increase the concentrations of rat plasma adrenocorticotrophic hormone (ACTH), corticosterone (CORT) and thyroid stimulating hormone (TSH). As for the effect of increasing organization nitric oxide (NO) and superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA), total ginsenoside is better than that of other groups. In brief, different components in ginseng possess different effects on enhancing immunity, regulating endocrine and resisting oxidation. Panaxadiol saponins and ginseng polysaccharide are better in enhancing immune, and total ginsenoside shows advantages in resisting oxidation and stress.
