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.

In order to optimize the ~(18)O labeling method, two key aspects, peptide dispersion and trypsin deac tivation were discussed o The addition of Rapigest SF in H_2~('8)O and microwave heating enhanced labeling efficiency of α-casein digested peptides(~(18)O/~(16)O) ratio >99%).Chemical modification with tris(2-carboxyeth yl) phosphine (TCEP) and iodoacetamide (IAA) resulted in trypsin deactivated completely.No significant back-exchange from ~(18)O to ~(16)O was observed after labeling in 6 days.The experiment result with peptide mixture from showed that the improved method could be effectively used to label protein and peptide.

To investigate the gene typing, molecular characteristics of virulence and resistance associated gene of Clostridium difficile from clinical isolates in China, the genes tcdA,tcdB of toxin A and B, cdtA,cdt B of binary-toxin, and erm B of clindamycin resistance were detected by conventional PCR. Genotyping of toxic C. difficile were conducted by means of analysis of 16s-23s internal spacer region polymorphism with PCR assay. Then the antibiotic resistance of toxic C. difficile to ampiciline, clindamycin, metronidazole and vancomycin was conducted with E-test. It was found that 8 toxic C. difficile strains were demonstrated out of 12 clinical isolates, in which 5 strains were tcdA+ and tcdB+, and 3 strains tcdA- and tcdB+, accounting for 62.5% and 37.5% respectively. Binary-toxin genes detection were negative in all the strains. Clindamycin resistance associated gene ermB was positive in 4 out of 8 toxic C. difficile strains, accounting for 50%. 8 toxic isolates were typed into 4 gene types, the dominant type was ZR I,accounting for 62.5%. Resistance rate of 8 toxic C. difficile strains against ampiciline(AC), clindamycin(CM), metronidazole(MZ) and vancomycin(VA) was 37.5%,87.5%,12.5%, and 0 respectively. No isolates belonged to ribotype 027 or 078. Isolation rate of toxic C. difficile is high to 66.7%. There is obvious gene polymorphism in clinical isolates of Chinese toxic C.difficite, and ZR I is preponderant genotype in 4 genotypes. C. difficile shows some resistance to ampiciline, clindamycin, metronidazole, but susceptive to vancomycin.

OBJECTIVE: To study the characteristics of pulmonary function in children with pertussis-like coughing caused by different pathogen infections. METHODS: The data on etiology and tidal breathing pulmonary function were collected from 95 hospitalized infants and young children with pertussis-like coughing. The tidal breathing pulmonary function was compared between these children and 67 healthy children. According to the type of pathogen, the children with pertussis-like coughing were classified to 6 groups: pertussis (n=17), viral infection (n=23), tuberculosis infection (n=6), Mycoplasma infection (n=9), other bacterial infection (n=8), and unknown pathogen (n=32). RESULTS: Among the 95 children with pertussis-like coughing, 15 (16%) had mild obstructive ventilatory dysfunction, 30 (32%) had moderate obstructive ventilatory dysfunction, and 22 (23%) had severe obstructive ventilatory dysfunction. Compared with the normal control group, the children with pertussis-like coughing had significant reductions in inspiratory-to-expiratory time ratio, ratio of time to peak tidal expiratory flow to total expiratory time (tPF%tE), and ratio of volume to peak tidal expiratory flow to total expiratory volume (vPF%vE) (P<0.05). The tuberculosis infection and Mycoplasma infection groups had a significantly lower tidal volume than the normal control group (P<0.05). All pathogen infection groups except the tuberculosis infection group had significantly lower tPF%tE and vPF%vE than the normal control group (P<0.05). The pertussis group had significantly lower tPF%tE and vPF%vE than the other infection groups (P<0.05). CONCLUSIONS Most of children with pertussis-like coughing have abnormal pulmonary functions. The children with Bordetella pertussis infection have the most severe pulmonary function impairment. Tidal breathing pulmonary function test may provide a reference for pathogen analysis of children with pertussis-like coughing.

Objective To study the distribution of Candida infection and drug tolerance in intensive care unit(ICU). Methods A retrospective study was conducted. The critical patients admitted from January 2011 to December 2013 in ICU of the First Hospital of Jiaxing in Zhejiang Province were enrolled,and their clinical data with positive Candida culture and drug susceptibility results in specimens of sputum,urine,blood,ascites,bile, etc were collected. In the study of these 3 years in ICU,the situation of Candida infection,the distribution of positive specimen,the condition of distribution of different strains of Candida,and the Candida tolerance to antifungal drugs were analyzed. Results From 2011 to 2013,2 412 times of patients(including one patient had admitted into ICU for more than one time)were admitted into ICU in which 407 cases were of Candida infection(16.9%),and the rate of Candida infection was rising gradually in the 3 years〔2011 to 2013 Candida positive rates were 13.4%(77/573), 16.1%(146/907),19.7%(184/932)〕,the difference being statistically significant(P<0.01). In the 407 strains of Candida,166 strains(40.8%)were isolated from sputum,157(38.6%)from urine,53 strains(13.0%)ascites, 13 strains(3.1%)blood,11 strains(2.7%)bile,7 strains(1.7%)from other specimens. The strain distribution of Candida was mainly as follows:Candida albicans(174 strains),Candida glabrata(131 strains),Candida tropicalis (83 strains),Candida parapailosis(5 strains),Candida krusei(12 strains),and 2 strains of rare Candida portugal and Lipolztica. From 2011 to 2013,the highest tolerance of Candida albicans,Candida glabrata,Candida tropicalis to fluconazole,itraconazole,Fushita Yasu and other antifungal drugs was in 2013,and the lowest was in 2012,the rates of tolerance of the above 3 strains of Candida to amphotericin B being 0,to itraconazole being the highest(10.9%, 27.8%,9.6%,respectively),to Fushita Yasu the secondary(6.6%,11.0%,0,respectively)and to fluconazole the last(4.7%,7.4%,1.9%,respectively),and the rates of tolerance of Candida parapsilosis,Candida krusei,Candida Portugal,Candida lipolztica to amphotericin B,fluconazole,itraconazole,Fushita Yasu were all 0. Conclusion In ICU,the Candida infection is mainly in the respiratory tract and urinary tract,its rate of infection has a tendency of rising,and the rate of Candida tolerance to itraconazole is the highest.

Objective To investigate whether rat adipose-derived stem cells (rASCs) could resist human xenoantibody-dependent complement-mediated lysis and to explore its possible mechanisms.Method SD rat ASCs were isolated,rASCs at passage 2 to 8 were used for the following studies and rat lymphocytes were harvested as control cells.α-Gal expression was detected by flow cytometry.After incubation of rASCs with 20％ normal human serum (NHS) or heat inactivated normal human serum (HINHS),flow cytometry was used to detect cytotoxicity,IgG or IgM binding,and C3c,C4c and C5b-9 deposition.Result We successfully established the method to isolate and culture rASCs.The morphology of rASCs remained unchanged after passages.rASCs were positive for tell surface markers of CD44 and CD90,while negative for CD45 and MHC-Ⅱ.As compared with rLCs,rASCs significantly resisted human natural antibody and complement-mediated lysis when incubated with 20％ NHS in vitro (20.42％ ± 2.80％ vs 51.84％ ± 6.70％,P ＜ 0.01).Mechanistically,rASCs expressed lower level of α-Gal (13.97 ± 0.33 vs.24.47 ± 3.03,P＜0.05),which was correlated with decreased binding of human xenoreactive IgG and IgM (IgM:9.4 ± 2.0 vs.107.2± 4.8,P＜0.01; IgG:5.73 ± 1.0 vs.27.49 ± 3.9,P＜0.01) and reduced deposition of complements C3c,C4c and C5b-9 (C3c:294.6 ± 38.02 vs.1924 ± 509.4,P＜0.05; C4c:35.23 ± 3.1vs.177.3 ± 37.17,P＜0.05; C5b-9:5.63 ± 1.74 vs.37.05 ± 7.4,P＜0.01).Conclusion These data demonstrated that the resistance of rASCs to human xenoantibody and complement-mediated lysis is associated with low expression of xenoantigen a-Gal and inhibition of MAC (membrane attack complex) formation.

Objective To design a multiplex PCR for simultaneous identification and toxigenic type characterization of Clostridium difficile isolates. MethodsThree pairs of primers were designed for the amplification of a species-specific internal fragment of the tpi( triose phosphate isomerase) gene, an internal fragment of the tcdB ( toxin B) gene, and an internal fragment of the tcdA ( toxin A) gene. Twenty-one standard strains including Clostridium difficile ATCC 9689 and 47 isolates of Clostridium difficile were applied for the assessment of detection limit, specificity and detections of the multiplex PCR, respectively. Toxin A and Toxin B of 47 isolates were analyzed by ELISA. ResultsThe detection limit for DNA concentration of the multiplex PCR was 0.5 pg/μl. The specificity was determined to be 100％. Among the results of 47 isolates detected by multiplex PC R, 37 strains were tpi ( + )/tcdA (+)/tcdB ( + ), 10 strains were tpi ( + )/tcdA (-)/tcdB ( - ). Tpi ( + )/tcdA ( - )/tcdB ( + ) was not found. The toxin detection of 47 isolates by ELISA showed that 20 isolates were positive and 27 isolates were negative. Twenty isolates of toxin (+) by ELISA were all tpi( +)/tcdA( +)/tcdB(+) by multiplex PCR. ConclusionThe multiplex PCR method combined diagnosis and toxigenic type characterization contributes to the diagnosis for Clostridium difficile infection.
