OBJECTIVE To investigate urogenital mycoplasma infection and its drug sensitivity in Beijing from Jul 2002 to Jun 2005. METHODS Mycoplasma were isolated and their antibiotic susceptibility was detected with Mycoplasma IST 2 Reagent Box from France. RESULTS Among 1806 cases 673 cases were with positive mycoplasma,accounting for 37.3% of the total.From them,Ureaplasma urealyticum(Uu) was positive in 541 cases(80.4%),higher than Uu combined with Mycoplasma hominis(Mh) infection(107 cases,15.9%) or Mh alone infection(25 cases,3.7%).The result of drug sensitivity test showed that Uu,Mh and Uu+Mh isolated from both sexes had different drug resistance.The most sensitive and stable antibiotics were josamycin(the rate of sensitivity was 98.7%) and pristinamycin(the rate of sensitivity 92.6%),the next was doxycyline(the rate of sensitivity was 91.8%).It seemed increasing sensitivity trend for tetracycline and erythromycin.The lowest rate of sensitivity was to ofloxacin and ciprofloxacin. CONCLUSIONS It is important to enhance the detection of drug resistance of mycoplasma,guide the drug use and prevent from producing antibiotic resistance.If antibiotic susceptibility testing of mycoplasma can not be tested,josamycin may be selected as the first choice to treat mycoplasma infection.

Objective To investigate the risk factors for deep vein thrombosis (DVT) after bone trauma.Methods The study involved 118 patients with traumatic fractures (traumatic fracture group),21 DVT patients diagnosed by color Doppler (DVT group) and 56 healthy patients (control group).Anti-cardiolipin antibody (ACA) was determined by ELISA method.D-dimer and fibrinogen (Fib) were detected by coagulation analyzer and C-reactive protein (CRP) by rate nephelometry.Results Levels of D-dimer,Fib and CRP in traumatic fracture group were significantly increased,but were lower than those in DVT group.ACA positive rate in DVT group presented significant increase and three patients with positive ACA in traumatic fracture group all suffered from DVT.The positive rates of Fib,D-dimer and CRP in lower limb fracture group,multiple fracture group and pelvic fracture group were higher than those in upper limb fracture group (P ＜ 0.05).Levels of Fib and D-dimer showed gradual rise with growth of age,but their levels in DVT group had different degree of reduction after thrombolytic therapy.Conclusions Positive ACA and enhancement of D-dimer,Fib and CRP are risk factors for DVT after bone trauma.Levels of Fib and D-dimer in patients with bone trauma are related with age and therefore risk of posttraumatic DVT increases with age.

Objective To observe the growth and biological features of bone mesenchymal stem cells (BMSC) from psoriatic patients. Methods Peripheral blood mononuclear cells were isolated from 5 patients with active psoriasis vulgaris and 5 normal human controls, and BMSC were obtained and purified using plastic adherence method followed by primary culture and passage in vitro. The cell morphology, density and growth were observed with microscopy. Cell growth pattern was evaluated by MTT assay. Flow cytometry was applied to identify surface antigens, including CD29, CD34, CD45 and CD106, on these cells. Results No significant difference was observed in the morphology of primary or descendant BMSC between the patients and controls.The primary BMSC from psoriatic patients tended to adhere to the plastic wall later, confluence and grow more slowly compared with those from the controls. The BMSCs from both psoriatic patients anti healthy donors were positive for CD29, but negative for CD34 or CD45. On the 4th day of culture, the BMSC from psoriatic patients exhibited a decrease in proliferation, with the absorbence at 470 nm (A470) being 0.081±0.0066 and 0.095±0.0130, respectively for BMSC from the patients and controls (t=2.358, P<0.05). Conclusion There is a decrease in the proliferation of BMSC from psoriatic patients which show a morphological similarity to those from healthy controls.

Objective To investigate the mammographic,galactographic,pneumographic features and their pathological basis.Methods Mammography(n=26),galactography(n=13),pneumography(n=5)and specimen radiography(n=12) in 26 cases pathologically proved,and mammographic-pathologic correlation were analyzed.Results The breast hamartomas in 26 cases were all benign,they were circumscribed and surrounded by a true capsule.The mammographic appearances could be divided into three types acording to different amount of fibroglandular and adipose tissue in tumors:prominantly fatty,prominantly fibrous(fibroglandular)and mixed fibrofatty.Conclusion A clearly containing areas of fat and fibroglandular density and a characteristic"slice of sausage"appearance can be showed on mammograms.Galactography and pneumography is of a great help to differential diagnosis of breast hamartomas.

Objective To study the effects of different anesthetic methods on stress response in patients during laparoscopic hysterectomy. Methods 45 patients scheduled for laparoscopic hysterectomy were randomly divided into three groups: group A (n = 15) , group B( n = 15) and group C (n = 15). blood samples was taken from patients in each group before anaesthesia, at 10 min and 40 min after pneumoperitomeum with CO_2 , 10 min after operation, to determine the glucose (BG) , catecholamine ( CA ) , C - response protein (CRP) and interleukins -6( IL -6). The changes of MAP ,HR,P_(ET)CO_2 and SpO_2 were also recorded. Results After anesthesia, the MAP, HR significantly decreased in group A (P 0.05 ). Conclusion Combined general epidural anesthesia can effectively inhibit the stress response in patients undergoing laparoscopic hysterectomy.
