FLIP is a protein containing death domain.Human beings have three subtypes of c-FLIPL,c-FLIPs and c-FLIPR,which can inhibit the apoptosis of a variety of tumor cells.c-FLIPL plays a dual role in the apoptotic signal.The expression level of FLIP not only decides the opening and closing of the apoptosis pathway but also achieve the conversion of cells in the apeptotic signaling and proliferative signaling pathway.The regulation of FLIP's expression is a multi-layered,involving multiple signaling pathways.FLIP will probably become an attractive death receptor signaling target of therapy.

Objective:To screen the best formula of tegafur temperature-sensitive gel for intratumor injection and investigate the in vitro drug release behavior. Methods:The drug dose was determined by cytotoxicity experiment. The thermo-sensitive gel was prepared with PLGA-PEG-PLGA and HPMC as the matrix. With the in vitro release as the index, the effects of PLGA-PEG-PLGA and HPMC at different concentrations on gel were investigated. The gelation temperature, viscosity and pH were detected. Results:The best formula was as follows:25% PLGA-PEG-PLGA, 1% HPMC, and tegafur dose of 1 mg·ml-1 . The average gelation temperature was 36. 7℃, the average viscosity was 7550 mPa·s, and the average pH was 7. 2. Conclusion:Tegafur thermo-sensitive gel for intratumor in-jection shows temperature sensitivity and obvious sustained-release property, which provides experimental basis for the further clinical research.

Objective To investigate the association between glucose metabolism status and brachial-ankle pulse wave velocity(baPWV)in Chinese patients with coronary artery disease(CAD).Methods baPWV values were measured in 198 CAD patients.Plasma glncose,serum lipids,hsCRP and other baseline data were obtained in all the patients.According to the glucose level,the participants were divided into 3 groups:normal glucose tolerance(NGT)group,impaired glucose regulation(IGR)group and diabetes mellitus(DM)group.ResultsbaPWV values in the DM group(1807±381)cm/s were significantly higher than those in the NGT group[(1615±248)cm/s,P=0.000]and IGR group[(1674±277)cm/s.P=0.035].Multiple stepwise linear regression analyses indicated that higher baPWv values were associated with aging and hsCRP levels in 198 patients.In DM group,higher baPWV values were independently associated with aging and HbA1 C levels.Conclusions In patients with coronary artery disease.baPWV values increase with different glucose metabolism status from NGT to IGR then DM.baPWV values in the patients with DM were significantly higher than those in the other two groups.Glycemic control may ameliorate arterial stiffness.

Objective To investigate the effects of calcium pyruvate supplementation on body weight gain and fatty acid metabolism in rats.Method Thirty-two 150 g male SD rats were randomly divided into four groups:control group,low,middle and high dose calcium pyruvate group (0,100,500 and 1000mg/(kg.d)).Calcium pyruvate was administered intragastrically to rats-for 4 w,and then the rats were killed and blood and tissue samples were collected.Serum lipids and blood glucose were determined by biochemistry analyzer.Analysis of fatty acid composition of adipose tissue,liver tissue and musculature was determined by capillary gas chromatography and mRNA expressions of ACC-? in liver by RT-PCR.Result At the end of the experiment,the body weight and food conversion efficiency of rats in all experiment groups were significantly lower than that of control group.TG of high and middle dose group were obviously lower than that of control group.TC and blood glucose concentration were not statistically different among different groups.contents of C16:0,c9-C18:1,c9,c12-C18:2,?-C18:3 and C20:4 in the adipose tissue were significantly decreased in the experiment groups,but the content of C18:0 was not statistically different on fatty acid composition of musculature in rats.Fatty acid composition of liver tissue was remarkably lower than that of the control group,except C18:0 and c12-C18:2.mRNA expression level of ACC in liver of high dose group was significantly decreased (P

Objective To investigate the features of variation of sympathetic skin response(SSR)in depression patients and to clarify the correlation between SSR and the effect of antidepressant therapy in first episode depression.Methods The sample comprised 50 first visit patients,who fulfilled the ICD-10 criteria in a structured interview for depressive disorder.These 50 patients received antidepressant therapy for 6 weeks.Clinical response was defined as ≥50%reduction in total 17-item Hamilton depression rating scale(HAMD).Remission was defined as HAMD score ≤7 at week 6.SSR waveforms were classified into three patterns based on the amplitudes of positive and negative components:P pattern,N pattern and M pattern.Another 50 healthy subjects were involved in this study as controls.Results (1)SSR could be obtained in all normal subjects but couldn't be recorded in 5 of 50 patients whose HAMD scores>28.SSR waveforul patterns were analyzed in these 45 patients P pattern in 7 cases,N pattern 21,M pattern 17.(2)Depression patients had longer latency and lower amplitude than the controls(P<0.01).P pattern had shorter latency and higher amplitude than N pattern.There were no difference in age,course and HAMD scores among the patients with 3 different SSR patterns.(3)Nine of 21 patients of N pattern treated with fluoxetine were remitters.6 patients were clinical responders.These 15 patients had shorter latency and higher amplitude after treatment than that at the initial stage,but there were still differences in latency and amplitude compared with the controls.Conclusion There were significant damages on sympathetic function of depression patients.N pattern was the most SSR pattern among 45 patients recorded SSR.P pattern had shorter latency and higher amplitude than N pattern.SSR is a sensitive and feasible measure inder for neurocardiac electrophysiologic autonomic regulation examination,which could be used to measure clinical therapeutic efficacy for antideppressant in depression patients.

Objective To evaluate the results of thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection.Methods From September 2005 to January 2013,30 patients with chronic type B aortic dissection received TEVAR.All patients were followed for 2-90 months [mean (33 ±25) months].Results All of the procedures finally achieved technical success.However,during TEVAR,there were transient endoleaks in 8 patients including type Ⅰ endoleaks in 3 patients,type Ⅱ endoleaks in 5 patients and persistent endoleaks in 3 patients which are type Ⅳ endoleaks.Type Ⅰ and type Ⅱ endoleaks were successfully managed during the procedures.There was no mortality or major complication during the perioperative period.Three patients died during follow-up:one patient died of carcinoma of the colon and two patients died of the complications of secondary interventions related to aortic dissection.Totally there were seven patients receiving secondary interventions.The Kaplan Meier actuarial survival curve showed a 5-year survival rate of 87.9％ and the 5-year survival rate without secondary intervention was 72.8％.Conclusions Early and midterm results showed that TEVAR was effective in treating chronic type B aortic dissection.

The corn germ protein tested was a by-product from, corn starch plant and it contained more lysine (average 5.7%) and a relatively ideal proportion of eight essential amino acids similar to the 1973 FAO/WHO provisional amino acid pattern. A 5-week rat growth experiment was conducted to evaluate the nutritive value of corn germ protein by using body weight gain, nitrogen balance and apparent net protein utilization as assessment criteria.The feed of the experimental group was made of wheat protein supplemented with 17.3% germ protein and that of the control with 2.4% wheat glu- ten to made the final protein level of both feeds equivalent to 10%.These results showed that the body weight gain of rat in the experimental group was higher than that of the control group regardless of female or male, the body weight gain per 100g feed consumed in two groups of female was 19.0g and 12.2g and that of male was 17.6g and 10.4g respectively (p

Objective:To observe the clinical efficacy of Yi Jin Jing (Sinew-transforming Qigong Exercises) for primary osteoporosis in the elderly.Methods:Eighty old patients with primary osteoporosis were randomized into a Yi Jin Jing group and a medication group,40 cases in each group.The Yi Jin Jing group was intervened by Yi Jin Jing (Sinew-transforming Qigong Exercises) training,while the medication group was intervened by oral administration of alendronate sodium tablet.Prior to and after 6-month intervention,the bone mineral density (BMD) of the proximal femur,visual analog scale (VAS) and activities of daily living (ADL) were estimated.Results:There were no significant differences in the BMD of the proximal femur,and VAS and ADL scores between the two groups before the intervention (P＞0.05).After 6-month intervention,the above items all improved significantly in both groups (both P＜0.01);the improvements in VAS and ADL scores in Yi Jin Jing group were more significant than those in the medication group (P＜0.01),while the between-group difference in the BMD of the proximal femur was statistically insignificant (P＞0.05).Conclusion:Practice of Yi Jin Jing (Sinew-transforming Qigong Exercises) can effectively ameliorate the BMD in the elderly with primary osteoporosis,and it can reduce the pain and improve ADL,with a better general effect compared to oral administration of alendronate sodium tablet.

Objective: To observe the clinical efficacy of umbilical therapy with herbal cakes made of Ge Gen Qin Lian Tang prescription of different dosages in treating damp-heat diarrhea in young children. Methods: Seventy-two kids with diarrhea of damp-heat pattern were recruited and divided into a high-dosage group and a low-dosage group using the random number table method, with 36 cases in each group. They all received conventional antidiarrheal treatment and umbilical application with herbal cakes. However, the herbal cakes for the high-dosage group were made of the mixture of Ge Gen Qin Lian Tang powder and water, and those for the low-dosage group consisted of 10％ Ge Gen Qin Lian Tang powder and 90％ auxiliary materials (corn starch) plus water. The treatment duration was 3 d. The clinical efficacy, antidiarrheal rate, effective rate for symptoms and signs of traditional Chinese medicine (TCM), TCM symptoms score, and safety indicators were compared between the two groups. Results: After the treatment, the TCM symptoms scores dropped significantly in both groups (P<0.01) and were lower in the high-dosage group than in the low-dosage group (P<0.05). The clinical efficacy was more significant in the high-dosage group than in the low-dosage group after the treatment, and the between-group difference was statistically significant (P<0.05); the antidiarrheal rate was markedly higher in the high-dosage group than in the low-dosage group (P<0.05). Regarding the TCM symptoms and signs, the high-dosage group showed better results in improving the greasy and yellowish tongue coating, bowel movement frequency, watery excrement, short and dark urine, red tongue body, red anus, vomiting, bowel sounds, and abdominal bloating compared with the low-dosage group, and the between-group differences were statistically significant (P<0.01). Conclusion: Umbilical therapy with herbal cakes made of Ge Gen Qin Lian Tang is safe, reliable, and effective in treating damp-heat diarrhea in young children; the high-dosage herbal cakes produce more significant efficacy than the low-dosage ones and are worth further investigation.
