Adipocytes are classified into three types, including white, brown, and “beige/brite” adipocytes. There exist differences in origin of adipocytes, gene expressions, morphology, and functions among three kinds of adipocytes. Multiple factors such as physical and chemical factors, neurohormonal and immunological factors, transcriptional factors have been shown to regulate and control the browning process and lipolysis of white adipose tissue. Thus, they may become new targets for anti-obesity intervention. In the process of obesity, chronic inflammation reaction, adipose tissue remodeling and abnormal angiogenesis occurring in the adipose tissue cause pathological fat expansion and reduce lipid storage in adipocytes. Understanding adipocytes biology is important to decipher how the aberrant adipose tissue contributes to obesity and metabolic disorders, and provides guidance for treating obesity.

Objective: To study the in vitro transdermal absorption characteristics of the free anthraquinones of rhubarb in Dasuan Xiaohuang Pasta (DXP) and investigate the effect of various excipients (vinegar, ginger juice, and vegetable oil) and different compatibilities on rhubarb transdermal characteristics. Methods: Taking rhubarb free anthraquinones, such as aloe emodin, rhein, emodin, chrysophanol, and physcion as indexes, the studies were carried out by in vitro transdermal absorption. Results: The transdermal absorption of free anthraquinones of rhubarb with various excipients and different compatibilities were all zero-order kinetics; Using vinegar as the excipient, the 8 h accumulation permeation amount and transdermal rate of every ingredient were the largest, followed by ginger juice and vegetable oil; In the different compatibility tests, the 8 h accumulation permeation amount and transdermal rate of each ingredient in anagraph were the largest, followed by rhubarb-sodium sulfate and rhubarb-garlic, and the single rhubarb was the lowest. Conclusion: DXP using vinegar shows the best, followed by ginger juice, while vegetable oil shows the worst. Garlic and sodium sulfate show the improvement on transdermal absorption of free anthraquinones of rhubarb, and sodium sulfate shows better effect than garlic.

Objective To study the ecological characteristics of toxigenic fungi in soil of the suburban villages of Zhangzhou, Fujian. Methods 48 soil samples were collected from 24 natural villages in Zhangzhou and cultured in bengal rose agar plate, then the fungal count and species identification were carried out. Results The numbers of fungi in unit area in 48 soil samples were in the normal rang. 3357 strains of 34 fungal genera were found in sampled soil samples. Fusarium and Penicillium were the dominant genera, as well as Trichoderma, Parcilomyces, Cladosporium which were commonly detectable. 4 strains of Aspergillus flavas were found, 2 of them were toxigenic. Aflatoxin B 1 production were 6?7 ng/g respectively and they didnt produce AFB 2? AFG 1? AFG 2. 2 strains of A. versicolor both produced sterigmatocystin. Conclusion Aspergillus flavus showed lower proportion in mycoflora and weaker capability for producing aflatoxins in soil of suburban villages of Zhangzhou. This data obtained could be used as the basis for agriculture areal programme.

Objective To investigate the expression and distribution of Kv1.6 in rat hippocampus after status epilepticus (SE) induced by lithium and pilocarpine to explore the relationship between Kv1.6 and epileptogenesis.Methods Forty-eight healthy male Sprague-Dawley rats were randomly divided into experiment group and control group.The rats in each group were randomly assigned into 6-hour,1-day,2-day and 3-day subgroups (n =6).Electroencephalography (EEG) of rats in both groups were recorded to show the electrical activity of the rat brains.Nissel staining was performed to investigate the pathological changes,and immunohistochemistry and Western blotting were applied to analyze the expression and distribution of Kv1.6.Results (1) The EEG of rats in control group showed α wave with uniform amplitude,while the EEG in rats subjected to pilocarpine injection showed slow waves and spike waves with irregular amplitude and rhythm.Sustained spike waves were observed during SE.(2) Nissl staining showed that 6 hours after SE,the neural morphology of hippocampi in experiment group was as the same to that in control group.There was no change in neuronal morphology and numbers.However,1 day after SE,the structure of hippocampi was discrete and the number of neurons was decreased.Two and 3 days after SE,the number of neurons in hippocampi decreased further.Swelling and deformation of neurons were seen.Nissl bodies emerged,decreased or even disappeared.(3) There was no statistically significant difference in the expression of Kv1.6 in CA3 and CA1 areas between experiment group and control group 6 hours after SE (all P＞0.05).One day,2 days and 3 days post SE,the expression of Kv1.6 in CA3 area (0.117 ±0.040,0.135 ±0.029,0.112 ±0.050) decreased obviously compared to control group (0.192±0.054,0.201 ± 0.062,0.184 ±0.042;t---3.861,3.745,5.579,all P ＜0.05);and the expression of Kv1.6 in CA1 area (0.114 ± 0.02,0.082 ± 0.031,0.106 ± 0.043) decreased significantly compared to control group (0.165±0.036,0.187 ±0.025,0.172 ±0.052;t=3.221,6.360,3.645,all P＜0.05).The expression of Kv1.6 did not show statistically significant difference in DG area between experiment group and control group at all time points examined (P ＞ 0.05).The Western blotting showed the same trend.Conclusion The decreased expression of Kv1.6 may play a role in the epileptogenesis.

Objective To understand current situation of surgery grading management in 22 hospitals from Beijing Municipal Administration of Hospitals,and to discuss the problems and to make suggestions for better application and management.Methods Based on general survey,Surgery of Grading Conditions of All Municipal Hospitals was issued to 22 municipal hospitals to make related staff fill related data.Results Except for 3 specialty hospitals,19 hospitals have launched the surgery grading management,while they are in different steps of implementing hierarchical directory,surgeon permission and dynamic management.These hospitals have different reference standards of making hierarchical directory.84.2％ hospitals give surgeons authorities according to levels of operations evaluated by professional title,surgery grade and doctors' technical skills.There are 14 hospitals applying information management on surgery grading.Conclusion Uniform criteria of hierarchical directory,extension of surgeon permission system and implementation of surgery grading information management will contribute to regulation fulfillment.

Objective To explore the effects of PSE on hemodynamics and Liver function in LCPH. Methods 30 patients with LCPH are treated by PSE. The hemodynamics changes of patients with LCPH are evaluated with color Doppler diasonograph. The changes of main clinical features which is related to LCPH , serum ALT and albumn were investigated . Results The hemodynamics indexs of LCPH are all changed significantly (P0. 05) between four and two weeks after PSE. But the main symptoms, signs of LCPH and liver function are improved after PSE . Conclutions PSE plays an important role in hemdynamics and liver function of LCPH. After PSE, Portal hypertension decreases effectively and liver function is improved.

Objective To investigate Enterococci resistance to glycopeptides and their genotypes. Methods MICs of antimicrobial agents to Enterococci were determined with agar dilution test and van genes were amplified with PCR. Results 298 E. faecalis and 42 E. faecium clinical isolates were collected from 13 University teaching hospitals around China. The resistant rates of E. faecalis to penicillins were 14.1%～17.8%, which was much lower than those of E.feacium. No glycopeptides resistant Enterococci strain was detected. 8 E. faecalis and 1 E. faecium were intermediate sensitive to vancomycin but sensitive to teicoplanin with MICs of 8～16 and 0.25～2 mg/L, respectively. PCR amplification of van genes gave rise to only vanC2/3 gene positive in E. faecalis B144. Conclusions Glycopeptide resistant Enterococci is not common in China and no vanA or vanB type Enterococci was detected in this study. Penicillins, vancomycin and teicoplanin could be employed in the treatment of Enterococcus faecalis infections. High attention should be paid to future development of vancomycin resistant Enterococcus (VRE) in China.
