More than one hundred strains of marine molds have been isolated from the sediment and the sample of seawater collected from the South China Sea. By the first screening, more than 30 strains of marine molds which can inhibit tested fungi such as Candida albicans and Fursarium sp. were obtained.The results of the second screening showed those strains designed as B 4#-6、B 4#-3、1-B 6-6、1-B 6-10-5、1-B 6-22、C 2#-5、A 2-9 and 1-B 6-10 can produced extracelluar antifungi metabolic products and the crude extract of the strains 1-B 6-10-5 and B 4#-3 can inhibit the growth of many other species of fungi.

It was widely believed that the interaction between rice and rice blast fungus can be interpreted by the gene-for-gene hypothesis. Two interaction models between rice blast fungus and anti-disease genes had been briefed. They were receptor-ligand model and guard model. The progress of research about molecular marker and position on avirulence genes of the pathogens of rice blast (Magnaporthe oryzae) was reviewed, and the methods to clone and the cloned avirulence genes of rice blast fungus were also summarized.

In order to study the spectral reflectance differences of Glycyrrhizae Radix under different growth conditions and lay the foundation for quantitative monitoring of Glycyrrhizae Radix remote sensing images, spectra of Glycyrrhiza species under different growth period and different varieties and different regions were measured by a portable spectrometer. The results showed that the reflectivity of annual G. uralensis was obviously higher than that of the two years plant in the visible light band own to the contents of crown layer chlorophyll. The reflectivity of two years G. pallidiflora was higher than that of G. uralensis in the near infrared band own to the leaf area index and the content of leaf water. The red edge spectrum of annual plant fluctuated largely than that of two years plant due to vegetation coverage and leaf area index. G. pallidiflora grew well than G. uralensis. Under different regions of the Glycyrrhiza species, spectral data analysis showed that within a certain range, the average annual precipitation and average annual evaporation were the major factors to affect the differences of Glycyrrhiza species spectral data under different regions owe to the leaf water content, the higher leaf water content, the lower spectral reflectance. The principal component analysis and continuum-removed method of the spectral data under different regions found that, within a certain range, the average annual precipitation and average annual evaporation were the major factors caused by the differences of Glycyrrhiza species spectral data under the different regions, Glycyrrhiza species spectral similarity related to the spatial distance.

A series of cycloberberine derivatives were designed, synthesized and evaluated for their anti-cancer activities in vitro. Among these analogs, compounds 6c, 6e and 6g showed strong inhibition on human HepG2 cells. They afforded a potent effect against DOX-resistant MCF-7 breast cells as well. The primary mechanism showed that cell cycle was blocked at G2/M phase of HepG2 cells treated with 6g using flow cytometry assay. It significantly inhibited the activity of DNA Top I at the concentration of 0.1 mg mL-1. Our results provided a basis for the development of this kind of compounds as novel anti-cancer agents.

OBJECTIVETo evaluate the intervention effect of diet, exercise and Jiangtang Bushen Recipe (JBR, a Chinese herbal recipe) in preventing the progress of patients with impaired glucose tolerance (IGT) to diabetes mellitus (DM) type 2.

METHODSFifty-one patients with IGT, with their diagnosis conformed to the diagnosis standard of WHO, 1999, were randomly divided into the control group (n = 26) and the TCM group (n = 25). Patients in the control group attended to the educational course for DM and received dietotherapy and kinetotherapy, and to those in the TCM group, under these treatments, JBR was given additionally. Oral glucose tolerance test (OGTT), body weight index (BWI), levels of blood lipids and fasting insulin of all the patients were examined after 3 months, 6 months and 12 months of treatment. The total observation time was 1 year.

RESULTSExcept the 6 cases out of the 51 patients (11.7%), on whom the observation discontinued, in the control group, as compared with before treatment, levels of fasting insulin and fasting blood glucose after treatment were not changed significantly (P > 0.05), also insignificant difference was shown in levels of total cholesterol (TC) and triglyceride (TG), though the two indexes lowered slightly after treatment (P > 0.05), but significant difference was shown in comparison of OGTT/2 h, blood glucose and BWI (P < 0.05). While in the TCM group, fasting blood glucose was changed insignificantly (P > 0.05), but there was significant difference in comparison of fasting insulin, TC, BWI, OGTT/2 h and plasma glucose levels (P < 0.01) respectively before and after treatment. At the end of the study, the cumulative cases with conversion to diabetes were 3 (13.6%) in the control group, and 1 (4.3%) in the TCM group, chi 2 test showed insignificant difference in comparison of diabetes conversion rate between the two groups (P > 0.05), however, the TCM group showed a better year conversion rate of normal glucose tolerance than that in the control group (chi 2 = 8.31, P < 0.01).

CONCLUSIONTCM intervention is possibly effective in delaying the conversion of IGT to DM type 2, and plays integrative effeciency in impelling IGT patients to health. The favorable education and treatment of DM controlling, including dieto- and kineto-therapy may also be advantageous in IGT intervention, but could not be effective in blocking the advance of IGT.

Objective To investigate the relationship between phenomenon of aggregation on multiple metabolic abnormalities and their family history.Methods A random cluster sampling was carried out to study the phenomenon of multiple metabolic abnormalities among the adult inhabitants in a county of Henan province.Questionnaire,physical examination and biochemical tests were admitted.Multiple correspondence analyses were used to explore the aggregation of multiple metabolic abnormalities among objects including hyperlipidemia,diabetes,coronary heart disease etc.Corresponding relationships between objects and their parents on multiple metabolic abnormalities were also analyzed.Results In total,3901 people were investigated including 1428 (36.6％) males and 2473 (63.4％) females.The mean age of them was 32.8 ± 6.3.Data showed that the Cronbach' s α were 0.547 and 0.387 while Eigen values were 1.971 and 1.535 in two dimensions,regarding the correspondence analysis on their parents' multiple metabolic abnormalities.Cronbach' s α levels were 0.598 and 0.457 together with Eigen values as 2.263 and 1.743 in two dimensions on the correspondence analysis of the objects' and their parents' multiple metabolic abnormalities.Results from Multiple correspondence analysis diagrams showed that there was an aggregation of varietymetabolic abnormalities in both objects and their parents but not between objects and their parents or between fathers and mothers,though x2 test showed a weak correlation between some of the categories.The ranges of contingency coefficients between metabolic abnormalities were 0.04 to 0.11,0.04 to 0.08 and 0.04 to 0.11 between parents,objects and fathers,objects and mothers,respectively.When compared with simple obesity,the central obesity aggregated appeared more obviously with other metabolic abnormalities.Conclusion Both objects and their parents showed an aggregation of variety metabolic abnormalities.Aggregation of central obesity showed more obvious on other metabolic abnormalities than the simple obesity.Family histories of metabolic abnormalities played a moderate role in the generations suffering from multiple metabolic abnormalities.

OBJECTIVETo review the diagnosis and treatment of interstitial pregnancy.

METHODSFour cases with complicated interstitial pregnancy were diagnosed and treated from January, 2004 to June, 2007 at the Affiliated Obstetrics and Gynecology Hospital, College of Medicine, Zhejiang University. The clinical data and follow-up records were analyzed retrospectively.

RESULTSAll 4 nulliparous patients were misdiagnosed before operation. The median age was 30 years (25-34 years), and the median duration of amenorrhea was 48 days (37-58 days). The median concentrations of serum beta-hCG were 3245.5 IU/L (282-30729 IU/L). Two patients with interstitial pregnancy had high levels of beta-hCG, and were diagnosed and treated under laparoscopy. Among them one patient was underwent transcervical curettage under laparoscopic guidance,and another underwent laparoscopic salpingotomy. The remained two patients had low levels of beta-hCG, and were diagnosed and treated under hysteroscopy, 50 mg methorexate(MTX)was injected into the implanted sites under hysteroscopic guidance. The levels of serum beta-hCG in 4 patients dropped down quickly, reaching undetected levels at a mean duration of 13 days after operation. Three months postoperatively, ultrasonic examination revealed the normal contour of uterus.

CONCLUSIONSEndoscopic examination is helpful to make a correct diagnosis, and transcervical curettage (or transcatheter chemotherapy) under laparoscopic guidance (or under hysteroscopic guidance) may be a promising approach for young or nulliparous women with interstitial pregnancy who want to maintain future fertility.
