OBJECTIVE To detect the Mycoplasma ureaplasma and Chlamydia infection in male urogenital system,and analyze their antibiotic resistance analysis and therapeutic strategies.METHODS Mycoplasma and their drug sensitivity were detected by culture method and analyze Chlamydia and Ureaplasma antigen with monoclonal antibody colloid gold assay.RESULTS From 320 specimens there were 18 cases who had Chlamydia trachomatis(5.6%) and 91 cases who had Mycoplasma(28.4%).The single infection of Ureaplasma urealytilcum(Uu) and M.hominis(Mh) and Ct was in 63 cases(19.7%) and 28 cases(8.8%),respectively,Uu+Mh were 10 cases(3.1%) and Uu+Ct were in 7 cases(2.2%).The result of drug sensitivity showed:doxycycline and minocycline had the higher bacteriostatic ability.CONCLUSIONS With the growing number of Mycoplasma,the resistant strains are incveasing.Experimental evidence showed doxycycline and minocycline can be used as the first choice for Mycoplasma and Ureaplasma infection,but roxithromycin be used carefully.

Objective To study the clinical effect of low-molecular-weight heparin combined with edaravone in the treatment of progressive cerebral infarction.Methods 60 patients with acute progressive cerebral infarction in 72 hours were randomly divided into treatment group received edaravone combined low-molecular-weight heparin(n=30)and control group received low-molecular-weight heparin(n=30).The primary efficacy was evaluated by NIHSS(the National Institutes of Health Stroke Scale).ADL(Activities of daily living)and clinical effect.Results Our study showed that the score of NIHSS on 7th day post-therapy and 14th day post-therapy in treatment group was lower than that in control group(t=15.987 and 11.756,both P＜0.01).However,the score of ADL in the theatment group on 14th day post-therapy was higher than that of control group(t=62.56,P＜0.01).The overall clinical responserate of treatment group was higher than that of control group(x2=13.695,5.769,all P＜0.01).Conclusion Edaravone combined with low-molecular-weight heparin has remakable effect on the treatment of progressive cerebral infarcti.

Objective: To detect estrogen receptor α and β(ER-α, ER-β)protein expression in different age of mouse thymus.Methods:Protein expression of ER-α and ER-β in thymus was analyzed via immunohistochemistry.Moreover,the relationship between ER-α and cytokeratin 18(epithelial cell marker)was further tested through fluorescence double-staining.Results: Immunohistochemical analysis revealed that both ER-α and β protein was found in nuclei of some thymocytes of 3 month mice.However,expression of ER-β was absence while ER-α was still positive in aged mice, such as 12 months and 16 months old.Double staining further confirmed that lots of ER-α/β positive cells were Foxp3 negative cells.Conclusion: Expression of ER-β is absent while ER-α is still positive in thymus of aged mice, which indicates ER-α is the critical estrogen receptor that involves in thymic involution.Moreover, ER-α/β do not participate in Treg development within thymus.

Objective To investigate clinical effect of reattribution-cognitive-pharmacy model (RCPM) in the treatment for irritable bowel syndrome(IBS). Methods 125 subjects with diarrhea predominant irritable bowel syndrome (IBS-D) were divided into two groups randomly. 62 patients in group A were treated with 10 ～ 20 mg of paroxetine without any other medication or psychological interview and 63 patients in group B received RCPM with interviewing once a week for 6 sessions and took 10 ～ 20 mg of paroxetine in the same way as group A after a week. The effect was evaluated at the end of 4 weeks and 12 weeks by a questionnaire. Results At the end of 4 weeks,29 patients in group A reported a reduction in abdominal pain,and 28 reported a reduction in stool frequency ,and 12 patients stopped taking paroxetine because of worrying about those side effect . In group B 48 reported a reduction in abdominal pain ,and 42 reported a reduction in stool frequency ,and 3 patients stopped taking paroxetine. At the end of 12 weeks,36 patients in group A reported a reduction in abdominal pain ,and 30 reported a reduction in stool frequency,and 14 patients stopped taking paroxetine because of worry about those side effect. In group B,54 cases reported a reduction in abdominal pain,and 45 reported a reduction in stool frequency,and 5 patients stopped taking paroxetine because of no obvious improvement. Conclusion RCPM can alleviate the abdominal pain and bowl movement frequency of IBS-D,and it seems better than paroxetine treatment alone. RCPM can improve compliance of paroxetine in patients with IBS-D.

Objective To explore the effects and mechanism in patients with ulcerative colitis (UC) treated by Yin Yang equilibrated preparation. Method 82 patients with UC as treatment group and 35 health parsons as control group underwent the testing. The serum and mucosal of all testing persons were taken pre and post treatment to detect CD+4 CD+25 regulatory T cells(Tregs) by flow cytometry at the end of one month,treating with SASP and Yin Yang equilibrated preparation. Result Compared with normal control group,the proportion of CD+4 CD+25 Tregs was markedly decreased in PB and mucesal of group A and B(P <0.01). But it was significanfly increased in therapeutic groups of SASP and Yin Yang equilibrated preparation, and their CD+4 CD+25 Tregs in PB and mucosal were much more than the control group at the end of one month after treating with SASP and Yin Yang equilibrated preparation(P <0.01 or P< 0.05). Conclusion CD+4 CD+25 Tregs with strong immune suppression play a central role in the initia-tion and development of UC,and the Yin Yang equilibrated preparation might exert its therapeutic effects on UC by the regulation of number and function of CD+4 CD+25 Tregs.

Objective:To explore the mediating role of family cohesion between family expressiveness and preschool children's behavior.Methods:Using the method of stratified cluster random sampling, the parents of 1 213 children in Shenzhen kindergartens were assessed by the Achenbach child behavior checklist (parent questionnaire) (CBCL, 4-16 years) and family environment scale-Chinese version (FES-CV). After the survey, SPSS 24.0 was used to conduct the data analysis and the Bootstrap method was used to test the mediation effect.Results:(1)The total score of children's behavior 147.0(135.0, 163.0) was found to be significantly negatively correlated with family expressiveness score 6.0 (5.0, 7.0) and family cohesion score 8.0 (6.0, 9.0), and the correlation coefficients were -0.145 and -0.187(both P<0.01). (2) Family expressiveness score was positively related to family cohesion score ( r=0.443, P<0.01). (3)The direct effect of family expressiveness on children's behavior was -0.072, and the 95% confidence interval was (-0.133, -0.010). Family cohesion had a mediating effect between family expressiveness and children's behavior, 95% confidence interval was (-0.129, -0.058), and the mediating effect accounted for 56.4% of the total effect. Conclusion:Family cohesion plays a partial mediating role between family expressiveness and children's behavior.

OBJECTIVETo identify the clinical predictors of atrial fibrillation (AF) after coronary artery bypass grafting (CABG).

METHODS322 consecutive patients who had undergone isolated CABG were reviewed. Preoperative, intraoperative and postoperative data were collected. Patients were grouped according to whether AF appeared postoperatively.

RESULTSAF occurred in 75 patients (23.3%). Most cases of AF (85.6%) appeared on or before the third postoperative day. The mean age for patients with AF was 62.5 years compared with 56.7 years for patients without AF (P < 0.05). The mean aortic crossclamp time for patients with AF was 67 min compared with 60.3 min for patients without AF (P < 0.05). The mean duration of cardiopulmonary bypass for patients with AF was 109.6 min compared with 97.3 min for patients without AF (P < 0.05). The mean duration of mechanical ventilation for patients with AF was 19.1 h compared with 15.7 h for patients without AF (P < 0.05). Multivariate logistic regression analysis was used to identify the following independent predictors of postoperative AF (P < 0.05): age > or = 65 years (OR 2.7; 95% CI 1.5 to 5.1), lesions in the right coronary artery (OR 2.5; 95% CI 1.4 to 4.5), and early postoperative withdrawal of beta blocker (OR 3.9; 95% CI 2.1 to 7.7).

CONCLUSIONSAF remains the most common complication after CABG. Age and lesions in the right coronary artery can influence the incidence of AF, and beta blocker and magnesium may be the most economical and effective prevention for AF early after CABG.

Objective To evaluate the role of multi-disciplinary team (MDT) in improving the diagnosis and treatment of human herpes virus-6B (HHV-6B) encephalitis after liver transplantation. Methods MDT consultation was delivered for one rare case of HHV-6B encephalitis after liver transplantation to establish an effective individualized treatment regime. Results On the 16 d after liver transplantation, the patient developed headache, and suddenly presented with unresponsiveness, unconsciousness, coma complicated with involuntary limb twitching on the 18 d. Blood ammonia level was increased. Brain CT scan showed cerebral ischemic changes. Electroencephalography prompted the epileptic seizure. After MDT consultation, the possibility of nervous system infection after liver transplantation was considered, and medication therapy was given to control the epileptic seizure. Cerebrospinal fluid examination via lumbar puncture hinted increased intracranial pressure. Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) of the cerebrospinal fluid demonstrated that the patient was tested positive for HHV-6B nucleic acid, which confirmed the diagnosis of HHV-6B encephalitis. The immunosuppressant regime was adjusted, intravenous ganciclovir was given for antiviral treatment, and active interventions were delivered to prevent and treat relevant complications. Epileptic seizure disappeared after 4 d, and neurological symptoms were significantly alleviated after 2 weeks. After 4-week antiviral treatment, the patient was tested negative for virology testing, and the neurological function was restored to normal. Conclusions HHV-6B encephalitis rarely occurs after adult liver transplantation, which is primarily associated with the virus reactivation after use of immunosuppressant. MDT pattern may be employed to deepen the understanding of the patient's condition, formulate more effective individualized treatment regime, and enhance the clinical efficacy and safety.
