It is reported that more than 95% microbe species non-cultured or un-cultured yet in now days by the traditional cultivation approach, which limits discovering novel bioactive compounds from microorganisms. ‘Metagenome’ is the genomes of the total microbiota found in nature. Metagenome libraries were constructed by directly extracting DNA from environmental sample and transforming to surrogate host. The libraries were screened for novel bioactive compounds or genes surrounding their synthase in different strategies of function-driven or sequence-driven. These have enormously amplified the space of microbial resource utilization and enhanced the opportunity of obtain novel bioactive compounds.

Recently,paclitaxel has been used as a new agent on patients with advanced esophageal cancer,and several studies have demonstrated that paclitaxel and paclitaxel-based regimens have significant activity in patients with advanced esophageal cancer and showed highly response rates than the combination of 5-fluorouracil (5-Fu) and cisplatin.However,there have been some problems which need to be solved such as drug-resistance,side effect,and so forth.The new medicament form of paclitaxel can not only depress poison without anti-allergy but also raise medicament curative effect as well as the pharmacal concentration.Although most of the research on the new medicament form of paclitaxel are still limited in the stage of laboratory,it has possessed potential advance in the treatment of advanced esophageal cancer.

Objective To investigate the clinical and pathological prognostic factors in patients with carcinoma of ampulla of Vater treated by pancreatoduodenectomy.Methods The clinical and pathological factors of patients with carcinoma of ampulla of Vater who were operated from February 1994 to February 2009 at the Urumqi General Hospital of Lanzhou Military Region were retrospectively analyzed.The survival curves of these patients were also analyzed.Results The post-operative 1-,3-,5-year survival rates were 90％,63％,55％ respectively.The diameter of the majority of tumor (58.3％) was less than 2.0 cm.Of all the patients with carcinoma of ampulla of Vater,48.7％ were in T1 stage,41.7％ had high grade differentiation,73.0％ had no lymphatic metastasis.Univariate analysis showed that gender,age,tumor diameter,biopsy or not,the type of operation,the value of pre-operative serum bilirubin and the value of serum CA19-9 were not related to survival.The gross type of tumor (P =0.018),histological type (P =0.000),grade of differentiation (P =0.003),depth of infiltration (P =0.003),lymphatic metastasis (P =0.014) and TNM stage (P =0.031) were significant impact factors of survival.Multivariate analysis showed histological type and depth of infiltration were independent prognostic factors of surviva1 (P =0.002,P =0.005).Conclusion Grossly ulcerated carcinoma,mucinous adenocarcinoma on histology,low degree of differentiation,T2/T3 stage,lymphatic metastasis and clinical stage of Ⅱb were all significantly associated with poor prognosis in patients with carcinoma of ampulla of Vater treated by pancreatoduodenectomy.Histological type and the depth of infiltration were the most important risk factors of survival.

Inflammasomes are multi-protein complexes that trigger the activation of caspase-1 and the maturation of interleukin-1β ( IL-1β) , which are critical for inflammation and control of pathogen infection. Inflammasomes are involved in and regulate diversified diseases due to its capability to sense multiple danger signals. In this review, we present the activation and regulation mechanisms for different inflammasomes and discuss how genetic mutations in inflammasome-related genes or abnormal activity of in-flammasomes lead to diseases. Insights into the role of inflammasome in various human diseases will provide sound theoretical basis and effective treatment strategy for these disease.

Objective To investigate the clinical effect of alendronate sodium on bone metabolism and bone mineral density (BMD) for treating the elderly female with osteoporotic distal radius fractures.Methods Ninety elderly female with osteoporotic distal radius fractures patients were divided into treatment group and control group with 45 cases each according to the method of random number list.The two groups were given the medication treatment after 3 d of external fixation stenting.The control group was given calcium dimension D and the treatment group was given alendronate sodium and calcium dimension D.The course of treatment was 6 months.Before and after treatment,the BMD and bone metabolism [bone alkaline pbosphatase(BALP),tartrate-resistant acid phosphatase-5b(TRACP-5b)] were detected in both groups.The wrist function of two groups was evaluated.Results Before treatment,the level of BMD of treatment group and control group were (0.472 ± 0.157),(0.519 ± 0.173) g/cm2,there was no significant difference (P ＞0.05).After treatment,the level of BMD of treatment group and control group were (0.893 ±0.298),(0.571 ± 0.184) g/cm2,the BMD of treatment group after treatment was significantly higher than that before treatment and control group after treatment(P ＜ 0.05).The level of BMD of control group after treatment had no significant difference compared with before treatment (P ＞ 0.05).Before treatment,the level of BALP,TRACP-5b of treatment group and control group were (53.76 ± 17.92),(5.61 ± 1.87) U/L and (51.86 ± 17.29),(5.54 ± 1.85) U/L,the level of BALP,TRACP-5b after treatment had significant difference compared with before treatment and control group after treatment (P ＜0.05).There was no significant difference in control group before treatment and after treatment (P ＞ 0.05).The good rate of rehabilitation of wrist function in treatment group was 91.1％ (41/45),significantly higher than that in control group [51.1％ (23/45)] (x2 =17.524,P ＜0.01).Conclusions The alendronate sodium has a role to suppress bone resorption and increase BMD.It can promote the recovery of wrist function.
