OBJECTIVE To study infection and drug resistance of Mycoplasma from female genital tract.METHODS Mycoplasma in cervical secretion from inflammed female genital tract were identified by cultivation,and the sensitivities to antibiotics were also performed.RESULTS Mycoplasma were detected in 318 specimens among 588 patients with genital tract inflammation(54.1%),among which Ureaplasma urealyticum(Uu) accounted for 312(98.1%),and Mycoplasma hominis was 6(1.9%).The resistance to 12 kinds of antibiotics indicated that the sensitivities to 8 kinds of antibiotics were higher than 80% and the sensitivities to erythromycin,spiramycin and tetracycline were the lowest.CONCLUSIONS The infectious rates of Uu are on big rise in female genital tract with inflammation and the resistant strains increase continuously.

Objective The prosthesis used for aortic valve replacement (AVR) can be too small in relation to body size,thus causing valve prosthesis-patient mismatch (PPM).The aim of this article was to summarize the preventive strategy of PPM during AVR.Methods A total of 357 patients [203 males,154 females; mean age (54.9 ± 18.7 ) years ] underwent AVR between February.2010 and December 2011.The weight and body surface area (BSA) of the group is( 60.1 ± 11.4 )kg and (1.67 ± 0.21 )m2 respectively.The aortic valve prosthesis effective orifice area (EOA) was divided by body surface area (BSA) to obtain the EOA index (EOAI).PPM was then defined as none or mild if EOAI was ＞ 0.85 cm2/m2,as moderate for (0.65 - 0.85 ) cm2/m2 and as severe for ＜ 0.65 cm2/m2.To avoid PPM,a simple three-step algorithm was applied:Step 1,Calculate the patient's BSA from weight and height;Step 2,Calculate the minimal valve EOA required based on the BSA to ensure an EOAI ＞0.85 cm2/m2 ; Step 3,Select the type and size of prosthesis that has reference values for EOA greater or equal to the minimal EOA value obtained in step 2.For patients with a small aortic root,the following three methods was used:( 1 ) Replace aortic valve with simple interrupted suture technique ; (2) Apply new type and high-performance prosthetic valves such as St.Jude Medical Regent mechanical valve ; (3) Enlarge the narrowed aortic root when necessary.Results Of all 357 patients,272 patients received mechanical AVR and 85 bioprosthetic AVR.Among the 49 patients who received AVR with simple interrupted suture technique.St.Jude Medical Regent mechanical valve was implanted in 38 patients and the aortic root enlargement was performed in 11 patients.The total prevalence of PPM was 6.4％ and there was no severe PPM.The prevalence of PPM with mechanical AVR and bioprosthetic AVR was 1.8％ and 21.2％ respectively.There were 4 deaths during early period of operation,and the operative mortality was 1.1％.Conclusion Prosthesis-patient mismatch can be effectively prevented at the time of AVR with appropriate measurement.

Objective To analyze the clinical and immunological manifestations of antiphospholipid syndrome(APS)in a cohort of 100 patients.Methods The clinical and serologic features of APS(Sapporo preliminary criteria)in 100 patients were analyzed retrospectively.Results The cohort consisted of 79 female patients and 21 male patients witb a mean age of 36?13 years at diagnosis.Primary APS was presented in 37% of patients;APS was secondary to systemic lupus erythematosus(SLE)in 46%,lupus-like syndrome in 14%. Eighty percent of the patients had thrombosis,43(54%)patients had venous thrombosis,18(22%)had arterial thrombosis,15(19%)had both arterial and venous thrombosis.4(5%)had thrombosis of microcirculation. Forty-two(52%)patients presented thrombosis at a single site,26(32%)at two sites,12(15%)at three or more sites.Forty-five(56%)patients experienced one thrombotic episode,20(25%)patients had only one re- currence,and 15(19%)had more thrombosis.The most common manifestations of thrombosis were deep vein thrombosis(36%),pulmonary embolism(30%)and stroke(26%),with heart,kidney,gastrointestinal tract and other organs involvements.Thirty-four(51%)female patients had spontaneous fetal losses including intrauter- ine fetus death and recurrent spontaneous abortion.Seventy-one(71%)patients developed thromboeytopenia. The presence of antieardiolipin antibody(ACL)was detected in 84 patients(84%).Among 90 patients with APS,alone ACL was detected in 38 patients(42%),both ACL and lupus anticoagulant(LA)were detected in 36(40%),LA alone in 16(18%).Patients with APS associated with SLE or lupus-like syndrome had higher frequency of arthritis,leukopenia,antinuclear antibodies(ANA)and low complement levels.Female patients had a higher frequency of leukopenia,ANA and ACL.Male patients had a higher prevalence of deep venous thrombosis in the lower limbs and LA.Conclusion APS is an autoimmune disorder characterized by recurrent arterial and venous thrombosis,fetal loss,or thrombocytopenia with the presence of ACL and/or LA.In APS secondary to with SLE,the patient's sex can modify the disease expression and define specific subsets of APS.
