PFTK1,an important member of cyclin dependent kinase Cdc2 family,is over expressed in many malignancies.PFTK1 involves in multiple processes,such as regulation of cell cycle,tumor invasion and metastasis,and the Wnt signal transduction pathway,which has a significant impact on prognosis of tumor.

OBJECTIVE: To establish the fuzzy model for rating of severity of adverse drug reactions(ADR) and to verify it with examples.METHODS: The principles of vague mathematics were employed for a fuzzy comprehensive evaluation.RESULTS & CONCLUSION: Employing fuzzy comprehensive evaluation to rate ADR based on its clinical manifestations is helpful for the concerned party in tightening monitoring on drugs with severe ADR meanwhile it provides references for clinicians about rational choice of drugs.

Gastric cancer is one of the most common malignant gastrointestinal tumors with a high mortality in China. However, the pathogenesis of gastric cancer is not clear. Recently, with the development of cancer stem cell research, more and more studies have been focused on the gastric cancer stem cell. In this review, we will discuss the conception and the study status of the gastric cancer stem cells in addition to the treatment for the cancer stem cell.

Liver metastasis is the leading cause of death from colorectal cancer (CRC).Multidisciplinary team model has become standard strategy for the diagnosis and treatment of colorectal liver metastases (CRLM),making individualized treatment through precise staging and molecular typing.Preoperative hepatic and regional arterial infusion chemotherapy and portal vein chemotherapy during surgery can reduce the incidence of liver metastases for stage Ⅲ CRC.Surgical resection of CRLM has been accepted by all scholars,and can be performed by minimally invasive surgery.The criteria for hepatic resection of CRLM have been extended including complete tumor resection,negative resection margin and adequate remnant liver volume.Simultaneous resections of primary tumor and liver metastases are safe and feasible.However,neoadjuvant chemotherapy is still controversial.For unresectable liver metastases,conversion therapy should be implemented to make the liver metastases become resectable.For unconvertible and unresectable CRLM,aggressive and comprehensive treatment is required to control the disease progression.

Objective To study the antagonism of taurine-zinc coordination compound (TZC) to the adverse effect of mercury (Hg) on the neurons in the cerebral cortex. Methods 32 male Wistar rats aged 21days were randomly divided into 4 groups, one control group (fed on distilled water), three experimental groups fed on HgCl2 (0.06 g/L), HgCl2+0.23 g/L TZC and HgCl2+0.46 g/L TZC respectively, treated for one month. The NOS activity in the cerebral cortex neurons was determined by NADPH-d histochemistry. Results NADPH-d positive neurons increased in HgCl2 group (P

Clinical experience of professor YANG Mu-xiang in treating hypertension,hyperplasia of prostate gland,acne and thyroid hyperfunction by brunellae spica were introduced,it was considered that the taste of brunellae spica was bitter and sweet,which was not hurt the spleen and stomach,and its cold nature was not consumption of yang,and it could remove hepatic heat,and have the function of eliminating stagnation.It was used when position of disease was liver,and pathogenesis was stagnation of liver qi or accumulation of heat;the dosage of 10-15g was used when the cooling-relieving heat accumulation therapy,and the dosage of 15-30g was used when eliminating stagnation.

ObjectiveTo investigate the effects of selective splenectomy on modulation of portal vein flow and prevention of small-for-size syndrome (SFSS) in living donor liver transplantation.MethodsTwenty six recipients who received LDLT from September 2007 to March 2008 were reviewed.The data of the portal vein flow of these recipients were collected during the operation.Simultaneous splenectomy was performed in patients with portal blood flow ＞250 ml/(min · 100g).No splenectomy was performed when the portal blood flow was less than 250 ml/(min · 100g).The effect of selective splenectomy on modulation of portal vein flow and whether splenectomy prevented the occurrence of SFSS were analyzed.ResultsThe portal vein flow decreased significantly after splenectomy in 8 patients who received splenectomy (P＜0.01),No SFSS occurred in the patients with or without splenectomy.Actual graft-to-recipient weight ratio (GRWR) of patients with splenectomy was significantly smaller than those with no splenectomy (P=0.044).The portal vein flow of patients with splenectomy was much higher than those with no splenectomy (P＜0.01).ConclusionAccording to the portal blood flow,selective splenectomy in LDLT decreased the portal vein flow and prevented the incidence of SFSS.

Pelvic inflammatory disease sequela (chronic pelvic inflammation) is one of the diseases that affect women's health conditions, and leads to large economic burden. Chinese Material Medica (CMM) plays an impor-tant role in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory). However, due to the lack of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflamma-tory Disease Sequela (Chronic Pelvic Inflammatory), non-standard phenomenon often appears in the research liter-ature, such as the selection of research methods, viewpoint of research, determination of cost, effect and utility. Thus, the publish of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflammatory Disease Sequela (Chronic Pelvic Inflammatory) is essential for the pharmacoeconomic evalua-tion of CMM in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory).

Varicose vein of lower extremity and varicocele show tortuosity,dilatation in different parts of venous.They are linked in venous anatomy structure.Their pathogenesis are not clear,but have certain similarity in venous wall structures,venous pressure,venous valvular incompetence,venous insufficiency,level of serum sex homone and apoptosis.We review the related literature to investigate the correlation between pathogenesis of them,in order to provide reference for the etiology,diagnosis and treatment.
