Objective To discuss the relationship between FokI gene polymorphism and colorectal canc-er.Method The references that met the inclusive criteria were assessed .The extracted data were summarized in the form of tables .Data were analyzed by heterogeneity test .Meta-analysis was conducted by using fixed effects model or random effects model .Results Fifteen experimental studies were included in this study ,including 7, 859 colorectal cancer patients and 9,933 controls.The association between VDR gene FokI and colorectal cancer was expressed as the odds ratio(OR)and 95% confidence interval(CI).FokI recessive genetic model,ff versus FF+Ff,ORrecessive=1.01(95% CI=0.87~1.17,I2 =54%,P=0.91),ORdominant =0.94(95% CI=0.83~1.06,I2 =64%,P=0.30);allele model,fversus F,OR=0.98(95% CI=0.89~1.08,I2 =71%,P=0.72).In subgroup analysis,recessive genetic model,ORCaucasian race =0.95(95% CI=0.86~1.05,I2 =0%,P=0.33);ORyellow race=1.12(95%CI=0.77~1.63,I2 =72%,P=0.54).In subgroup analysis,dom-inant gene model,ORCaucasian race =0.95(95% CI=0.86~1.04,I2 =27%,P=0.29);ORyellow race =0.89(95%CI=0.65~1.22,I2 =78%,P=0.47).In subgroup analysis,allele model,ORCaucasian race=0.97 (95%CI=0.90~1.04,I2 =31%,P=0.38);ORyellow race =1(95% CI =0.79 ~1.27,I2 =82%,P=1.00).Conclusion Our results suggested that in VDR gene FokI ,F and f alleles were not obviously directly correlated with colorectal cancer .No difference was found between Asian and Caucasian .The conclusions in other populations should be further identified by extensive experimental studies .

Animal models using for research the cancer matestasis should be entirely similar to the clinical pathological process in patients.Currently,two kinds of animal models with genetic engineering and human tumor xenografts are available in laboratory,which provide a possible research tool to investigate the mechanism of tumor metastasis and explore the experimental treatment.In these models,the techniques including how to select the cell lines and using real-time imaging detection are very important factors.

Objective To investigate the protective effects of Apigenin (APG) on hepatic in diabetic rats.Methods The experimental diabetes model were made by intraperitoneal injecting STZ. The rats were randomly devided into six groups: a normal control group, a diabetes model control group, APG 5, 10, 20 and 40 mg/kg treated groups, and the drug was given by intraperitoneal injection. 4 weeks later, the body weight, ratio of hepatic weight and body weight were detected; the histopathological changes of hepatic tissue were observed by HE staining; the content of ALT/AST/LDH in serum were determined; the activity of SOD/GSH-Px/CAT and the content of MDA in hepatic tissue were determined.Results Compared with the diabetes model control group, the body weight of APG(10, 20, 40) mg/kg treated groups were significantly increased (261.3 ± 15.8 g, 274.2 ± 18.4 g, 265.9 ± 19.0 gvs. 250.8 ± 21.4 g,P<0.05 orP<0.01), and the ratio of hepatic weight and body weight were significantly decreased (27.7 ± 5.69, 26.2 ± 4.91, 27.3 ± 4.58vs. 32.9 ± 5.85,P<0.05 orP<0.01); the hepatic tissue histopathological changes of APG-treated groups were significantly improved; the level of ALT in serum of APG (5, 10, 20 and 40) mg/kg treated groups were significantly decreased (1 039.3 ± 453.9 U/L, 917.6 ± 445.2 U/L, 828.4 ± 309.5 U/L, 721.7 ± 318.3 U/Lvs. 1 205.2 ± 484.1 U/L;P<0.05 orP<0.01), AST were significantly decreased (97.8 ± 23.8 U/L, 90.1 ± 19.6 U/L, 81.7 ± 15.7 U/L, 86.4 ± 19.2 U/Lvs. 105.3 ± 25.7 U/L;P<0.05,P<0.01), LDH were also significantly decreased (983.7 ± 192.6 U/L, 918.3 ± 212.9 U/L, 830.4 ± 174.2 U/L, 871.8 ± 183.1 U/Lvs. 1 102.8 ± 211.6 U/L;P<0.05 orP<0.01); the activity of SOD in hepatic tissue of APG (10, 20, 40) mg/kg treated groups were significantly increased (10.5 ± 1.9 U/mg, 11.6 ± 2.1 U/mg, 10.5 ± 2.0 U/mgvs. 9.1 ± 1.8 U/mg,P<0.05,P<0.01), GSH-Px were significantly increased (14.2 ± 2.7 U/mg, 15.3 ± 2.9 U/mg, 14.6 ± 2.6 U/mgvs. 12.9 ± 2.3 U/mg;P<0.05, P<0.01), CAT were significantly increased (3.15 ± 0.90 U/mg, 3.58 ± 0.88 U/mg, 3.31 ± 1.09 U/mgvs. 2.58 ± 0.79 U/mg,P<0.05 orP<0.01), and the content of MDA was significantly decreased (5.03 ± 1.70 nmol/mg, 4.66 ± 1.51 nmol/mg, 4.73 ± 1.65 nmol/mg vs. 5.98 ± 1.62 nmol/mg;P<0.05 orP<0.01). And the treatment effect of APG 20 mg/kg groups was the most significant.Conclusion APG had antioxidant enzyme activity, besides its reducing the damage of free radical, and protecting the hepatic tissue of diabetic rats effects.

Amyotrophic lateral sclerosis is a progressive neurodegenerative disorder involving primarily motor neurons in the cerebral cortex,brainstem and spinal cord.The clinical diagnosis of ALS may be categorized into four levels of certainty according to clinical and electrophysiological examination,depending on the presence of upper and lower motor neuron signs together in the same topographical anatomic region in either the brainstem(bulbar cranial motor neurons),or cerival,or thoracic,or lumbosacral spinal cord(anterior horn motor neurons).Electromyography is of great importance in the diagnosis of ALS.Neruoimaging studies and clinical laboratory studies are helpful to exclude other disorders.

Purpose:To study the effect of recombinated human granulocyte colony-stimulating factor (rhG-CSF,filgrastim) on leukopenia induced by chemotherapy.Methods:Ten cases of leukopenia of grade Ⅳ induced by chemotherapy of malignant tumor were treated with rhG-CSF . When WBC2.5?109/L, rhG-CSF was stopped.Results:All patients with leukopenia of grade Ⅳ recovered to normal after treatment with rhG-CSF , the average time of usage was 6.8 days. The infection rate was 60%(6/10). Conclusions:Filgrastim is effective in the treatment of leukopenia of grade Ⅳ after chemotherapy, rhG-CSF decreases infection and facilitates chemotherapy.

Tacit knowledge is critical to a hospital's scientific and technological innovation, the basis for its survival and the major driving force for its sustainable development. It constitutes the bulk of a hospital's knowledge, including chiefly technological elements, cognitive elements, experience elements. emotional elements and belief elements, has priority among its various tasks, and is the basis for and the key to the development of individual and organizational abilities to innovate. The instruction on and inheritance of tacit knowledge plays a key part in the cultivation of innovative talents in a hospital. Thus hospitals ought to strengthen the management of tacit knowledge and realize its exchange and sharing through face-to-face communication, post rotation, the establishment of cross-disciplinary teams and electronic networks, and the coding of tacit knowledge.

Heterotopic gastric mucosa of the upper esophagus( HGMUE)is a rare esophageal disease. It is considered as a result of immature development of esophageal mucosal epithelium in embryonic period. Most of patients have no specific symptoms. The diagnosis of HGMUE is mainly based on endoscopy and biopsy. With the development of endoscopic technique,the detection rate of HGMUE is elevated and increasing attention has been paid to this disease. This article reviewed the clinical research on HGMUE.
