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.

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.

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

The study aims to investigate the effect of the ratio of long axis to short axis (RLS) of upright polypropylene infusion bag on discharging process and to search the best RLS. Aiming at five different RLS (1. 5 : 1, 2 : 1, 3 : 1, 4 : 1 and 5 : 1, respectively) with the volume of 100 mL, 250 mL and 500 mL, respectively, based on finite element method, analyzing the variation of stress distribution, emptying rate, drugging space and steadiness coefficient, etc. For the bags of the same volume, emptying rate increased with increasing of RLS, but the steadiness coefficient decreased with increasing of RLS. The specific increasing amplitude of emptying rate and decreasing range of steadiness coefficient were as follows: 20% and 49% for 100 mL infusion bag, 9% and 51% for 250 mL infusion bag, and 11% and 46% for 500 mL infusion bag, respectibvely, when RLS increased from 1. 5 : 1 to 5 : 1. Comparatively speaking, the increasing amplitude of the emptying rate is remarkably less than the decreasing range of the steadiness coefficient. By comprehensive consideration of both emptying rate and steadiness coefficient, lower RLS is recommended for upright polypropylene infusion bag.

Objective To study the correlation between male primary varicose vein of the lower extremity and varicocele.Methods 100 male patients with varicose vein of the lower extremity were compared with 100 male adults without varicose vein of the lower extremity for the prevalence of varicocele by using ultrasonography.Results There is no difference of demographic data between the two groups (t =1.78,P ＞ 0.05).There were 49 (49.0％) patients found with varicoele in study group compared with 19 (19.0％) patients with varicoele in control group (x2 =20.05,P ＜ 0.01).We compared the rate of varicoele and the mean diameter of spermatic vein between the patients having reflux in the saphenofemoral junction or not,and found there was no statistical difference between themn (rate of varicose P ＞ 0.05,diameter P ＞ 0.05).In patients with both lower extremity varicose vein and varicocele there was a linear correlation between spermatic vein diameter and that of varicose vein (rs =0.407 2,P ＜ 0.01).When patients in study group were classified into six grades by Clinical-Etiology-Anatomy-Pathophysiology (CEAP) trend chi-square found no difference in the incidence of varicoele (x2 =0.879 8,P ＞ 0.05),nor the mean diameter of spermatic vein in different grades (F =1.59,P ＞ 0.05).Conclusion There is a correlation between varicose vein of the lower extremity and the pathogcnesis of varicocele.
