Objective:To evaluate the efficacy and safety of moxifloxaction and levofloxaction in the treatment of the lower respiratory tract inflection.Method:64 cases patients were randomly divided into two groups.The clinical trial group was treated with moxifloxaction 400mg once a day,orally for 7-10 days and the controlled group treated with levo- floxaction in 200mg twice a day for 7-10 days.Result:The effective rate of the moxifloxaction group(93.9%)was high- er than that of the levofloxaction group(71.8%),but not significantly.The recovery rate of the moxifloxaction group (71.8%)was significantly higher than that of the levofloxaction group(46.9%);the days of recovery of clinical symptoms were not significantly different in the two groups.There was no significant difference between the two groups in the bacterial eradication rate.Conclusion:Moxifloxaction is effective and safe in the treatment of the lower respiratory tract inflection.

The antishock properties of Fu-tze "801" , an active fraction isolated from the root of Aconite,were studied on burned rats. The rats were given 65-70% TB'SA second degree scalds. All animals died in a short time postburn. Using this rat model, it was found that the marked spasmodic rhythmic constriction in arterioles occurred and the microierculatory flow state showed pronounced derangements in the me-senteric microcirculation, and platelet aggregate increased in circulating blood.After treatment with Fu-tze "801" , the survival and the mirocirculation were improved in the scalded rats, these findings suggest that Fu-tze "801" affords the antishock action on rats after a major scald burn.

CONCLUSION: Ephedrine shows a fast rate of absorption in guinea pig,serum concentration of ephedrine is stable and lasting potency,and indicates the reason of transdennal administration of Herba Ephedrae preparation.

OBJECTIVE: To observe the clinical effect of mini-plate fixation on the treatment of children unstable fractures of the distal ulna and radius. METHODS: A total of 18 children with unstable fracture of the distal ulna and radius (15 boys and 3 girls, aging 4.1-13.3 years, with the mean age of 9.8 years) were selected from Department of Orthopaedics, Wuhan Children and Women's Hospital, Tongji Medical College, Huazhong University of Science and Technology from August 2006 to September 2009. The fracture occurred on right side (n=9) and left side (n=9). All children were treated with mini-plate fixation which was instead of the traditional pinning fixation. Before operation, stainless steel or titanium plates of adult digital bone, metacarpal bone, and metatarsal bone were chosen according to fracture types and sites. The distance from fracture line to epiphyseal plate was measured to get ready the T-, L-, clover or straight plates. Joint function, degree of forearm rotation loss, bone healing, and complications were monitored postoperatively and within following up. RESULTS: All cases were followed up in out-patient for an average 26.4 months. An average 10°limitation was measured on forearm pronation function of all children, but the function was recovered by doing exercises which did not influence daily activities. Supination, flexion and extension of wrist joint were generally normal, and the fracture was generally healed. Complications including re-displacement, refracture, malunion, delayed union, bone bridge formation, vascular and nerve injury were not found. CONCLUSION: Patients who were not satisfied with the reduction, re-displacement, or old distal radius fracture needed an open reduction. Micro-plate was fixed to avoid epiphyseal injury of distal forearm and reduce postoperative complications. An ideal mini-plate may replace the traditional pinning fixation.

Objective To explore the role of intercellular adhesion molecule-1(ICAM-1) in the metastasis of lung cancer.Methods The expression of ICAM-1 in the tissue and the serum ICAM-1(sICAM-1) level in the 52 cases of primary lung cancer were detected with immunohistochemical staining method(SP) and enzyme linked immunosorbent assay(ELISA),with 20 cases of adjacent non-cancerous tissue as the control.Results The positive rate of ICAM-1 expression in lung cancer was significantly higher than that of adjacent non-cancerous tissue.The expression of ICAM-1 in the cases with lymph node metastasis was higher than that of no lymph node metastasis.The expression of ICAM-1 in stage III+IV was higher than that of stage I+II,and that in adenocarcinoma was higher than that of squamous cell carcinoma.The level of sICAM-1 in patients with lymph node metastasis was higher than that without lymph node metastasis.The sICAM-1 level in patients of adenocarcinoma was higher than that of squamous cell carcinoma,and that in patients with positive expression of ICAM-1 in tissue was higher than that of negative expression of ICAM-1.Conclusion The expression of ICAM-1 may be associated with the metastasis in lung cancer.The sICAM-1 level reflects the expression of ICAM-1 in tissue and may be used as a tumor marker of metastasis and prognosis in lung cancer.

Objective To discuss the diagnostic value of high frequency ultrasound on lesions of knee traumas.Methods Ninty-eight cases with post-traumatic knee injuries were examined by high frequency ultrasound,and the characteristics of changing ultrasonogram were observed and comparing with surgical results and MR.Results Of the 98 cases with post-traumatic knee injuries,there were 57 cases with effusion and hematocele in knee joint,among which there were 41 cases with collateral ligaments and meniscus injuries,the diagnostic coincidence rate was 93.3% in tendon tear and complete tendon fracture(compared with MR),91.7% in partial and complete muscle tear(compared with MR),67.7% and 71.4% in collateral ligaments and meniscus injuries(compared with surgical results).Conclusions High frequency ultrasound can be used as a conventional imaging examination method for post-traumatic knee injuries.

Objective To study the correlations of anxiety and depression at different phases with curative outcomes in female patients at IVF-ET cycle.Methods One hundred and seventeen patients were involved the study using the Self-Rating Anxiety Scale (SAS), Self-Rating Depression(SDS)questionnaires when registered for IVF-ET cycle(T1), one day prior to oocyte retrieval(T2), and 5 to 7 days after embryo transfer(T3).SDS scores and SAS scores were compared between different phases.Logistic regression was used to analyze the correlation of SAS scores with outcome.Results SDS scores of T1, T2 and T3 phases showed no significant differences(all P<0.05).The SAS scores at T2 and T3 were higher than that at T1(all P<0.05), the SAS scores at T2 were higher than that at T3(P<0.05).The SAS scores at T2 in patients achieved clinical pregnancy were significantly lower than that in patients achieved no clinical pregnancy.Logistic regression model showed that lower SAS scores were associated with higher pregnancy rates (P<0.05).Conclusions Anxiety level is the most remarkable one in the phase prior to oocyte retrieval.Low anxiety level prior to oocyte retrieval predicts higher a pregnancy rate.

Objective　To explore the relationship between hemolymph phenol oxidase and the melanization of Plasmodium yoelii oocysts in Anopheles dirus. Methods　An Anopheles dirus-Plasmodium yoelii system was used Anopheles dirus were divided into 3 groups, that is, non-blood-fedding (N), normal-blood-fedding (B) and infected-blood-fedding (I). The activities of MPO and o-DPO in hemolymph from 3 groups were determined with native polyacrylamide gel electrophoresis (PAGE) and density scanning at 5, 7, 11 and 15 d after blood feeding. Results　Both MPO and o-DPO activity were significantly higher in group I than group N and B (P<0.05). But with the melanization of Plasmodium yoelii oocysts, both MPO and o-DPO activity in group I were decreased in comparison with group N, especially on the 15 th day after infected-blood feeding. MPO and o-DPO activity in group B were significantly stronger than those of group N. Conclusion　Blood feeding and infection of Plasmodium yoelii both can activate the cascade. The heamolymph phenol oxidase may play an important role in the melanization of Plasmodium yoelii oocysts in Anopheles dirus.
