OBJECTIVE:To observe clinical efficacy and safety of pidotimod combined with montelukast sodium in the treat-ment of children with bronchial asthma. METHODS:120 children with bronchial asthma were randomly divided into control group and observation group,with 60 cases in each group. Both group were given routine treatment as aerosol inhalation of glucocorticoid and anti-infective treatment. Control group was additionally given Montelukast sodium chewable tablet 5 mg orally,qd,at bed-time;observation group was additionally given Pidotimod capsule 0.4 g,qd,on the basis of control group. Both group received treatment for consecutive 3 months. Clinical efficacies of 2 groups were observed as well as IL-4,IFN-γ,IgE,T lymphocyte sub-set and lung function indexes of 2 groups before and after treatment. The occurrence of ADR were compared between 2 groups. RE-SULTS:The effective rate of observation group was 88.3%,which was significantly higher than that of control group (61.7%). There was no statistical significance in IL-4,IFN-γ,IgE,T lymphocyte subset and lung function indexes between 2 groups before treatment(P>0.05). After treatment,IL-4,IFN-γ,IgE,CD4+,CD4+/CD8+ and lung function of 2 groups were improved signifi-cantly,and the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Pidotimod combined with monte-lukast sodium is effective for children with bronchial asthma,and can significantly relieve airway inflammation,enhance immunity and improve lung function with good safety.

Objective To observe the accuracy of abdominal ultrasound combined with transvaginal ultra-sound in the early diagnosis of ectopic pregnancy,thus to provide reference for clinical diagnosis of ectopic pregnancy. Methods The clinical data of 68 patients,who pathologically confirmed or conservative treatment with clinical diag-nosis of ectopic pregnancy,were retrospectively analyzed.All patients were treated with abdominal ultrasound,vaginal ultrasound examination.The accuracy and missed ectopic pregnancy rate of transvaginal ultrasound and abdominal B ultrasound and joint inspection were observed.And the presence or absence of abnormal ovarian uterus were recorded. Results By comparison with pathological diagnosis,joint diagnosis of 32 cases of ectopic pregnancy,the diagnosis rate was 94.1 %,missed 2cases,accounted for 5.9%;Transvaginal ultrasound diagnosis were 26 cases,accounted for 76.5%,missed by 8 cases,accounted for 23.5%;Abdominal ultrasound diagnosis were 24 cases,accounted for 70.6%,missed 1 0 cases,accounted for 29.4%.Joint inspection diagnosis rate was significantly higher than abdominal or vaginal ultrasound(χ2 =1 6.75,1 4.38,all P <0.05),and then compared transvaginal ultrasound and abdominal ultrasound diagnosis rate(P >0.05).Transvaginal ultrasound detected primitive heart tube pulse,mass,blood flow and gestational sac -like structures within the mass were significantly higher than the probability of abdominal ultra-sound(χ2 =26.71 ,7.1 8,1 0.25,50.28,25.69,6.39,all P <0.05).Conclusion United abdominal ultrasound and transvaginal ultrasound can significantly improve the early detection rate of ectopic pregnancy,which can provide refer-ence for clinical diagnosis and treatment.

Fifty-two patients with chronic thrombeembolism (41 male, 11 female) aged 33-67 yr underwent pulmonary endarterectomy between 1997-2008. Anesthesia was induced with etomidate, fentanyl/ sufentanil and rocuronium/vecuronium and maintained with large doses of narcotics supplemented with low concentrations of isoflurane/sevoflurane if necessary. Swan-Ganz catheter was placed after induction of anesthesia. Trausesophageal echocardiography was monitored. Bilateral pulmonary thromboembolism was performed using profound hypothermia with circulatory arrest. After operation, 35 patients still had sustained pulmonary hypertension (67%). Nervous system complications occurred in 7 patients ( 14% ). Six patients developed lung bleeding (12%) during and after operation and 4 patients infection (8%). The mortality was 15%.

OBJECTIVE:To observe the efficacy and safety of moxifloxacin combined with Jiehe pill in the treatment of muilt drug-resistant tuberculosis(MDR-TB). METHODS:116 patients with MDR-TB were randomly divided into control group and ob-servation group. Control group was given Moxifloxacin hyohochloride tablet 0.4 g once a day,observation group was additionally given Jiehe pill 9 g,twice a day,and 2 groups were given rifapentine,albendazole isoniazid,amikacin,pasiniazide,pyrazin-amide,p-amino salicylic acid and other conventional treatment. The treatment course for both groups was 18 months. The clinical efficacy,and T cell subsets (CD3+,CD4+,CD4+/CD8+),interferon(INF)γ,interleukin(IL)4 levels before and after 6,12 and 18 months,and incidence of adverse reactions in 2 groups were recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,CD3+,CD4+,CD4/CD8 and INF-γ level in 2 groups were significantly higher than before and gradually increased by time,and observation group was high-er than control group;IL-4 level was significantly lower than before and graually decreased by time,and observation group was lower than control group,the differences were statistically significant(P<0.05). There was no significant difference in the inci-dence of adverse reactions(P>0.05). CONCLUSIONS:Based on the coventional treatment,moxifloxacin combined with Jiehe pill has better efficacy than moxifloxacin in the treatment of MDR-TB,with similar safety.

[ABSTRACT]OBJECTIVETo evaluate the clinical value of ultrasound guided fine-needle aspiration (US-FNA) in the diagnosis of thyroid nodules with different size.METHODSThe clinical data of 122 thyroid nodules of 109 cases referred to FNAC for diagnosis were retrospectively reviewed. The final operating histological results of 122 nodules were considered gold standard. RESULTSNon-diagnostic FNAC results occurred in 17 nodules (13.9%). FNAC achieved a sensitivity of 78.6%, a specificity of 93.9%, a positive predictive value of 93.6%, a negative predictive value of 78.3%, and a total accuracy of 85.7%. There was no significant difference between the diameter of the nodule≤1 cm group and>1 cm group, except negative predictive value. The non-diagnostic results rate was no significant difference between groups of different nodule size, benign or malignant nodules, and different operators. CONCLUSIONFNAC is a sensitive, specific and accurate method for differential diagnosis of thyroid nodules.
