OBJECTIVE To investigate and analyze hand carrier state of medical staff in Tianjin and the antibiotic resistance of the pathogens.METHODS Bacteria or pathogens were isolated from the samples using a sterilized cotton swab on the whole hand before hand washing or hand disinfection,and drug sensitivity test was performed.RESULTS In 16.72% of all samples(50/299),there were 64 kinds of bacteria or pathogens isolated.A.baumannii,Staphylococcus aureus and A.lwoffii were the most common bacteria,40.6% resistant to more then 3 kinds of drugs.Four Meticillin-resistant S.aureus(MRSA) strains were detected out.CONCLUSIONS The high rate of hand carrying bacteria and resistance in Tianjin should pay attention to.

Objective To observe the effect of intra-articular injection of sodium hyaluronate (Na-HA) on mRNA expression of inducible nitric oxide synthase (iNOS) in cartilage of osteoarthritis (OA). Methods Sixteen white rabbits were underwent unilateral anterior cruciate ligament transection and were divided into 2 groups randomly 5 weeks after transection. Experimental group rabbits received 0.3 ml of intra-articular 1% Na-HA injection once a week. Animals in control group were treated with the same conditions using normal saline. All animals were sacrificed 10 weeks following surgery. The aritcular cartilage degeneration of medial femoral condyle was evaluated at mascroscopically and microscopically. The mRNA expression of iNOS in cartilages was analyzed by reverse transcription-polymerase chain reaction (RT-PCR). Results Cartilage degradation in experimental group was significantly less severe than that in control group. No significant difference of iNOS mRNA expression in cartilage was found between the experimental group and the control group. Conclusion Na-HA can significantly reduce the severity of cartilage degradation of OA. Na-HA dose not show definite effect on iNOS expression in cartilage during early stage of OA.

Objective To investigate the role of sLOX?1 and leptin in metabolic syndrome ,glucose and lipid metabolism. Methods 58 patients with metabolic syndrome were included in the study ,with other 35 normal controls as control group. Fasting venous blood samples were collected. ELISA method was used to detect serum sLOX?1 and leptin levels. The related biochemical indicators were tested. Results The sLOX?1 and leptin levels in the metabolic syndrome group were significantly higher than those in the control group(P < 0.01). The levels of sLOX?1 and leptin were further compared between different genders. The differences were not statistically significant (P > 0.05). sLOX?1 and leptin levels were positively correlated. They were positively correlated with WAIST,TG,SBP,DBP,and negatively correlated with HDL?C. Leptin and age,FPG also had positive correlation,but sLOX?1 was not correlated with age and FPG. Conclusion sLOX?1 may be able to predict endothelial damage in patients with metabolic syndrome in an early stage. Combined with leptin ,the endothelial dysfunction could be reflected more accurately. They may be the important factors for early diagnosis and risk assessment of metabolic syndrome.
