Objective To evaluate the effect of azithromycin on mycoplasmal pneumonia (MP).Methods We divided 90 MP cases into azithromycin and erythromycin treatment groups. In azithromycinThe pyretolysis time, cough improvement time, the disappearing time and the mean length of hospitalization of azithromycin group were shorter than that of erythrornycin group. The local ache, stomach and intestinal tract adverse reaction, and damage of hepar function were less than these in erythromycin group. ConclusionAzithromycin is an effective and safe drug to MP.

Objective Investigation of the Hexi Corridor in Gansu Province in the pathogenesis of esophageal cancer risk factors, prevention and treatment for esophageal cancer provide the basis. Methods Based on the hospital case control study, a survey of the region' s incidence of esophageal cancer risk factors. Results The single factor, multi factors and Logistic regression analysis found that Large quantities of alcohol, eating less fresh vegetables and less meat,eggs and fish, hot drink and diet, family history of esophageal cancer, history of significant mental trauma and low education level factors and esophagus cancer incidence closely related to the incidence of esophageal cancer in the Hexi Corridor is the main risk factors. At the same time, smoking, eating fast, eating sauerkraut was not related to the incidence of esophageal cancer. Conclusion After the investigation discovered this local esophagus cancer morbidity dangerous factor and locality special living conditions factor related, mainly displays in diet aspects and so on habits and customs and energetic factor. These factor function is by no means independent, but is affects mutually, affects mutually forms.

Background: Acute mastitis is an acute infectious disease of breast. Antibiotic treatment is often unable to obtain a good effect, and we should actively look for a safe and effective non-drug therapy. Objective: To validate the clinical efficacy of kneading and dispersing manipulation in treatment of early-stage acute mastitis. Design, setting, participants and interventions: According to the multicenter randomized controlled trial design, 198 cases of acute mastitis from Yueyang Hospital of Integrated Traditional Chinese Medicine, Longhua Hospital, and Shanghai Yangpu Maternity and Child Health Hospital were randomly divided into treatment group and control group. There were 99 cases in each group. Patients in the treatment group were only treated with manipulation, and cefradine was orally administered to patients in the control group. Main outcome measures: The local breast lump size, clinical symptoms and the adverse reactions in the two groups were observed before and after the treatment. Results: The total response rates in the treatment and control group were 95.92% (94/98) and 80% (76/95) respectively. There was a significant difference in the total response rate between the two groups (P<0.05). There were significant differences in the score of breast lump size, and the score of signs and symptoms between the two groups (P<0.05). Conclusion: Kneading and dispersing manipulation has certain effects on early-stage acute mastitis, and the therapy is safe and repeatable.

BACKGROUND:There is a high morbidity after spinal cord injury, and the therapeutic strategy is limited to early surgical intervention, medication and post-treatment exercise that only can improve the motor function slightly. However, there is no effective cure method. OBJECTIVE:To study the effect of partition-type spinal cord catheter combined with bone marrow stromal stem cels on T8 spinal cord transection damage in rats. METHODS:Fifty rats were randomized into five groups (n=10 per group): group I, T8 spinal cord transection (5 mm) was made in rats with no treatment; group II, the partition-type tube was inserted into the injured site after modeling; group III, partition-type tube combined with bone marrow stromal stem cels was implanted into the injured site after modeling; group IV, partition-type tube combined with polyglycolic acid fibers was implanted into the injured site after modeling; group V, partition-type tube combined with bone marrow stromal stem cels and polyglycolic acid fibers was implanted into the injured site after modeling. RESULTS AND CONCLUSION:At 2 and 12 weeks postoperatively, Basso, Beattie and Bresnahan scores were significantly higher in the groups III and IV than the groups I, II, IV (P < 0.05). At 12 weeks postoperatively, the latency of motor evoked potential below the injury plane was significantly decreased in group V compared with groups I, II, III, IV (P < 0.05). Immunohistochemical results displayed that in the groups III and V, regenerated nerve fibers grew positively and arranged orderly among the tubes, and there was no obvious winding phenomenon. Under transmission electron microscopy, a certain number of myelinated nerve fibers were found as bridges among groups. These findings indicate that the partition-type chitosan tube combined with bone marrow stromal stem cels has a good connection with the injured spinal cord a good connection to restore part of electrophysiological properties, accelerate the axon regeneration, recover the motor function, thereby providing a new direction for the treatment of spinal cord injury.

Objective To determine whether the susceptibility to ischemia-reperfusion injury in aged heart is higher than that in adult heart and,if so,to clarify the mechanisms underlying this change.Methods Wister rats(5-or 20-month-old)were randomly divided into 4 groups(6 animals in each group).The rats were subjected to 30 minutes of myocardial ischemia via ligating the left anterior descending coronary artery,followed by 3 hours of reperfusion(Young-MI/R group and Old-MI/R group);A silk suture around the left anterior descending coronary artery was not ligated in young and old rats(Young-sham group and Old-sham group).Myocardial apoptosis was detected by terminal deoxynueleotidyl transferase biotin-d UTP nick end labeling(TUNEL)staining and caspase-3 activity was detected by using a caspase-3 colorimetrie assay.Nitrotyrosine content,a footprint of in vivo ONOO~-formation,and total NO content were determined by ELISA and chemiluminescence method respectively.Results A significantly exacerbated cardiac reperfusion injury was found in Old-MI/R group as evidenced by increased TUNEL positive myocytes[(19.0?2.1)% vs.(14.6?1.7)%],and increased myocardial caspase-3 activity[(436?35)?mool/mg vs.(340?32)?mol/mg] compared with Young-MI/R group(P＜0.05).Aged hearts had a markedly increased basal NOx level compared with young adult hearts.Marked higher myocardial nitrotyrosine content was found in OId-MI/R group[(7.25?0.18)nmol/g]than that in Young-MI/R group[(4.68?0.15)nmol/g] (P＜0.05).Conclusions In aged hearts,high levels of NO might form highly toxie derivant, ONOO~-,and its subsequent nitrified protein.This may attribute to the increased susceptibility of the aged heart to isehemic-reperfusion injury.

A capillary electrophoretic method was developed for the separation of enantiomers of naphthylgly-cidic ether(NGE). Several cyclodextrins(CDs) were applied as the chiral selectors and it was found that the ionic modified highly sulfated cyclodextrin(HS-β-CD) could give satisfactory enantioselectivity. In addition,the effects of the pH value of the buffer system,the concentration of the HS-β-CD,capillary temperature and the running voltage on the chiral separation were investigated systematically. The result showed that under the optimized conditions of pH 2. 5,20 mmol/L H_3PO_4-triethanolamine buffer containing 2% highly sulfated cyclodextrin ( HS-β-CD) at capillary temperature 20℃ in the reversed polarity voltage of - 18 kV,the enantiomers of naphthylglycidic ether were baseline separated. This method is simple,precise and can be applied to the chiral separation of naphthylglycidic ether enantiomers and determination of enantiomers excess(ee,% ).

The results of open-field test,step-through passive avoidance task and radial-arm maze experiment showed that changes of locomotor activity,anxiety-related behaviour and ability of learning and memory were associated with the increased apoptosis of neurons in hippocampus in rats with perinatal hypothyroidism.
