As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective The purpose of the study was to understand the resistance status of to anti-tuberculosis drug in Yunnan province, and to provide evidence for tuberculosis (TB) control. Methods The proportional method was used in drug sensitivity test according to the guidelines recommending by WHO. Results Of 301 mycobacterial isolates, 279 (92.7%) strains were complex (MTBC) . The total drug resistance rate was 31.5% (88/279),the initial drug resistance rate of was 27.3%, and the acquired drug resistance rate was 44.3%. The drug resistance rates to INH,RFP,EMB and SM were 19.7%, 10.8%, 12.9%and 19.0%, respectively. The multi-drug resistance (MDR) rate was 9.3%. Conclusion The drug resistant rate of is still high in Yunnan province,and TB control is still a long way to go. Early detection and regular treatment should be done for MDR patients. Drug resistance monitoring as an important part of TB control programs should be regular observation and research.

OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

Under the optimum level determined, the yield is increased by 15%.

Objective To elucidate the influence of fetal genotype in both non-diabetic gravidas and pregnant women on gestational diabetes mellitus (GDM) through analysis of the genotype discrepancy between maternal and fetal Pro12A1a single nucleotide polymorphism (SNP) of peroxisome proliferator-activated receptor gamma 2 (PPARG2) genes.Methods Pregnant women,who delivered in the Obstetrics and Gynecology Hospital of Fudan University from October 2005 to February 2007,and their newborn babies were selected,and were divided into GDM and control group.The GDM group consisted of 55 gravidas with GDM and 40 newborns born to the GDM mothers,and the control group consisted of 173 healthy gravidas and their 50 neonates.Polymerase chain reaction-denaturing high-performance liquid chromatography was applied to detect the distribution of PPARG2 Pro12Ala alleles in all subjects.The concentrations of plasma fasting blood sugar (FBS) and several bio-markers of lipids,including total cholesterol,triglyceride,apoprotein A,high-density lipoprotein and low-density lipoprotein,were also tested for the mothers.Results (1) No significant difference was found in the frequencies of Pro/Pro genotype between the GDM mothers and control mothers (94.6% vs 90.8%,P > 0.05),nor between the GDM offspring and control offspring (95.0% vs 94.0%,P >0.05) or between the GDM mothers and GDM offspring (P > 0.05).The same was shown in the frequencies of Pro/Ala genotype both between the GDM mothers and control mothers (5.5% vs 9.2%,P >0.05) and between the GDM offspring and control offspring (2.5% vs 3.0%,P > 0.05).(2) Within both GDM and control group,the maternal FBS and various lipids concentrations of Pro/ Pro genotype gravidas showed no significant difference compared to those of Pro/Ala genotype mothers (P > 0.05).(3) Based on the four possible PPARG2 genotype pairs between the mothers and fetuses,Pro/Pro mother and her Pro/Pro fetus,Pro/Ala mother and her Pro/Ala fetus,Pro/Ala mother and her Pro/Pro fetus,and Pro/Pro mother and her Pro/Ala fetus,less Pro/Pro pairs and more Pro/Ala pairs were found in the GDM group than in the control (72.5% vs 92.0%,P=0.014; 27.5% vs 6.0%,P< 0.05).Conclusions Neither the maternal nor the offspring's Pro/Ala genotypes is associated with the genesis of GDM.However,the discrepancy of PPARG2 Prol2Ala polymorphism between mother and her fetus implies a possible cause of GDM.

OBJECTIVETo report and assess the efficacy of a coupled exofixator in the treatment of comminuted fracture of the humeral shaft.

METHODSFrom June 1999 to September 2003, 24 patients with comminuted fracture of the humeral shaft were treated in our department, in whom 11 were involved in left humerus fractures and 13 in right humerus fractures. Closed reduction or open reduction with a small incision as well as a coupled exofixator was used to treat these patients.

RESULTSAll cases got anatomical reduction after 6-12 months follow-up. The time for fracture union averaged 5.8 months with a good functional recovery of the shoulder-elbow joints.

CONCLUSIONSThe coupled exofixator is favorable to the treatment of comminuted humeral shaft fractures. It can shorten union time and avoid nonunion occurrence.

Nowadays,oil-pollution of seawater in the world has severely threatened the security of sea entironment.Bioremediation offers one available option for an oil spill response.The aspects as follows are introduced some evolvement of microbial ecology,including new method of survey of microbial diversity without cultivation,new isolated method and the properties of main hydrocarbon degradated strain.But we have little or no understanding of the vast majority of marine bacteria that remain uncultured,and more efforts should be made to improve current methods for isolating oil-degrading or oil-emulsifying bacteria,not only for assessing the fate and effects of the spilled oil,but also for isolating novel bacteria that would be useful for the petroleum industry.

A low-temperature hydrocarbon-degrading strain T7-2, isolated from sea-mud of Bohai polluted area and identified as Rhodococcus erythropolis, was found to produce an extracellular, nondialyzable emul- sifying agent (referred to as bioemulsifier) when grew with hexadecane as carbon source. The results showed that, this bioemulsifier which could remarkably emulsify hydrocarbons such as diesel oil, is consisted of three parts-carbohydrates, lipids and proteins, the proportion of which was 55.43:31.24:12.65. The mono- saccharide compositions were identified as mannose and rhamnose; the lipid compositions included de- canoic acid, lauric acid, hexadecanoic acid and stearic acid, and the protein constituents were composed of sixteen amino acids. Besides, according to the study of the physic-chemical properties of the bioemulsifier, it possesses the obvious advantages of character stability, high function efficiency and wide adaptation range, therefore this bioemulsifier is believed to have extensive application values for bioremediation of marine oil pollution, petroleum exploitation and etc.

A new molecular method for simultaneously rapid detection and differentiation of Mycobacterium tuberculosis, Mycobacterium bovis, Mycobacterium avium and Mycobacterium paratuberculosis was established by using denaturing high-performance liquid chromatography (DHPLC) combined with multiplex nucleic acid amplification. These 4 important pathogenic mycobacteria were identified by separation of 4 specific PCR-amplified target fragments by DHPLC analysis. A total of 51 Mycobacterium strains and 22 other bacterial species were tested to confirm the specificity of the multiplex PCR-DHPLC assay. The sensitivity of the assay was as low as 10~2-10~3 gene copies. This method rapidly identify the positive clinical samples from human and bovine with higher detection ratio than traditional culture method and was able to identify simultaneously four pathogenic Mycobacterium, which provided a new molecular tool for rapid detection of tuberculosis and paratuberculosis in human and animals.

Aim To evaluate the effects of salvianolic acid B ( Sal B ) on bone metabolism and its potential mechanism in high fat diet ( HFD) mice.Methods Thirty C57BL/6J male mice were divided into three groups with 10 mice each, namely normal , HFD and HFD+Sal B.HFD and HFD+Sal B mice were treated with HFD, and HFD+Sal B group mice were also with Sal B (125 mg· kg -1· d-1).After 12 weeks' treat-ment, femurs were harvested .The effects of Sal B on biomechanical strength were evaluated by biomechani-cal tests, and the effects of Sal B on bone microstruc-ture were evaluated by Safranin O/fast green staining and hematoxylin and eosin staining .The expression of nuclear factor-kappa B ( NF-κB)-p65 and NADPH ox-idase 4 ( Nox4 ) and cathepsin K in femurs was deter-mined by immunohistochemical staining . Results Maximum load and elastic load significantly decreased ,and the trabeculae became thinner and irregular in the femurs of HFD mice , while Sal B treatment could re-verse the descending biomechanical strength and the disorganized femurs bone micro-structures in HFD mice.In addition, the expressions of Nox4, NF-κB-p65 and cathepsin Kmarkedly increased in HFD mice , and Sal B possessed the ability to down-regulate the ex-pression of Nox4, NF-κB-p65, and cathepsin K in the femurs triggered by HFD .Conclusions Sal B treat-ment improves bone metabolism via regulating Nox 4/NF-κB/cathepsin K signaling pathway in HFD mice . The findings contribute to the understanding and exten-sion of the applications of Salvia miltiorrhiza and its constituents on osteoporosis .
