AIM: To investigate the expression and effects of sialyl Lewis X (SLeX) on the invasion and migration of human hepatocellular carcinoma HepG2 cells.METHODS: The expression of α1,3-fucosyltransferase VII (FUT7) in HepG2 cells and L-02 cells was detected by RT-qPCR and Western blot.The SLeX expression in HepG2 cells and L-02 cells was determined by Western blot and immunocytochemical staining.The invasion and migration abilities of the treated cells were evaluated by Transwell assay.RESULTS: The expression of FUT7 and SLeX in the HepG2 cells, but not in the L-02 cells, was observed.The invasion rates of the HepG2 cells treated with SLeX monoclonal antibody at 0.05, 0.5 and 5 mg/L were significantly decreased as compared with control group (P<0.05).The migration ability of the HepG2 cells treated with SLeX monoclonal antibody at 0.05, 0.5 and 5 mg/L was also significantly reduced as compared with control group (P<0.05).The invasion rate and migratory cell number were significantly different between any 2 groups in the HepG2 cells treated with SLeX monoclonal antibody at 0.05, 0.5 and 5 mg/L (P<0.05).CONCLUSION: HepG2 cells express SLeX.SLeX is closely related to the migration and invasion abilities of the HepG2 cells.

Objective To determine the difference in blood microcirculation recovery between normal frostbite and high-altitude frostbite during the wound healing.Methods Twenty four male rats were randomly divided into control group (n=8), normal frostbite group (n=8), and high-altitude group (n=8). The normal frostbite group rats were frozen to produce mid-degree frostbite models by controlling the freezing time with liquid nitrogen penetration equipment. The high-altitude frostbite group rats were acclimated to a hypoxic and low-pressure environment for 1 week, and then the high-altitude frostbite models were constructed by the same way with liquid nitrogen penetration apparatus. On days 3, 7, 11, 15, 19, and 23 after modeling, the recovery situation of blood circulation of each group was observed with contrast ultrasonography by injecting SonoVue micro-bubble into rats' tail. Finally, the micro-bubble concentration (MC) was calculated to confirm the blood circulation recovery with software Image Pro. ResultsAt different time points, the wound area of the high-altitude frostbite group was bigger than that of the normal frostbite group, and the MC of control group was always about (27±0.2)×109/ml. On day 3, 7, 11, 15, 19, and 23, the MC was significantly lower in the high-altitude frostbite group than in the control group and normal frostbite group (P<0.05). The MC of normal frostbite group was significantly lower than that of the control group on day 3, 7, 11, 15 and 19 (P<0.05). In addition, no obvious difference in MC was found between normal group and control group on the 23th day (P<0.05).Conclusion The blood microcirculation recovery after high-altitude frostbite is significantly slower than the normal frostbite.

Chinese medicine and Tibetan medicine both belong to the traditional medicine, and have their unique background and theoretical systems. There are similar features and differences in diagnosis of disease, syndrome and treatment between Chinese medicine and Tibetan medicine. Tibetan Zhenbu disease is common and frequently-occurring in plateau area with high morbidity, which is corresponding to rheumatoid arthritis in modern medicine and the category of Bi syndrome in Chinese medicine. During a long period of clinical efficacy verification, Tibetan treatment of Zhenbu disease presents to be little side effects, good curative effect, safe and economic etc. In the review, according to the introduction of Tibetan medicine and Chinese medicine, Zhenbu disease of Tibetan medicine and Chinese Bi syndrome will be compared in their pathogeneses and treatments to understand advantages and peculiarities of Tibetan medicine. The development of Tibentan medicine in the future will also be pointed out.

Objective To investigate the clinical distribution and change in antimicrobial resistance of Acinetobact-er baumannii (A.baumannii)from a hospital between 2011 and 2013,so as to provide guidance for clinical treat-ment.Methods Sources and antimicrobial susceptibility testing results of A.baumannii from a hospital were ana-lyzed statistically.Results A total of 14 705 bacterial isolates were isolated in 2011 —2013,13.59%(n=1 999)of which were A.baumannii isolates,the percentage of A.baumannii in isolated pathogens in 3 years was 12.74%, 13.05%,and 14.85% respectively,which showed a rising trend (χ2 =9.458,P =0.002).The main specimen was sputum (n = 1 541 ,77.09%),bacteria were mainly isolated from patients in respiratory disease department (21 .71 %),surgical intensive care unit (16.26%),and emergency intensive care unit (8.26%).Antimicrobial re-sistance rates of A.baumannii increased year by year(all P <0.05);multidrug-resistant and extensively drug-resist-ant A.baumannii also increased year by year (all P <0.001).Conclusion Isolation rate and antimicrobial resistance rate of A.baumannii strains increase year by year,multidrug-resistant and extensively drug-resistant A.baumannii strains are obvious,which should be paid more attention in clinical department.

OBJECTIVE: To explore the effects of low molecular weight heparin (LMWH) on cisplatin (DDP)- induced apoptosis in human hepatocellular carcinoma cell and the underlying mechanisms.
 METHODS: Hepatocellular carcinoma SMMC-7721 cells were divided into a control group, a LMWH group, a DDP group and a LMWH plus DDP group. The effect of the drugs on proliferation of hepatocellular carcinoma SMMC-7721 cells were evaluated by 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di- phenytetrazoliumromide (MTT) assay, and the apoptosis were detected by acridine orange/ethidium bromide (AO/EB) double fluorescence method and flow cytometry method. The expression levels of apoptosis-related protein Fas, Bcl-2 and Bax were detected by quantitative real-time PCR and Western blot.
 RESULTS: Compared with the control group, the proliferation of SMMC-7721 cells was inhibited in the DDP group and the LMWH plus DDP group (both P<0.05). The mRNA and protein levels of Fas, Bcl-2, Bax in the SMMC-7721 cells were not obviously changed in the LMWH group (all P>0.05). The Fas level was increased obviously (P<0.05), while the Bcl-2 level moderately reduced (P<0.05), Bax were not obviously changed in the DDP group (P>0.05). Compared with the control group and the DDP group, the Bcl-2 level was reduced significantly in the LMWH plus DDP group (both P<0.05), while the level of Bax was increased obviously (both P<0.05). Compared with control group, the Fas level was increased significantly in the LMWH plus DDP group (P<0.05), but the increase was not significant compared with the DDP group (P>0.05).
 CONCLUSION LMWH can enhance the cisplatin-induced apoptosis in SMMC-7721 cells, which might be related to activation of mitochondrial pathway.
