To evaluate the efficacy and safety of Azithromycin in the treatment of the bacterial infections. Method s: 94 patients with lower respiratory tract infection were randomly d ivided into 2 groups(47 for each gruop). The treated group were given Azithrom ycin 500mg in 5% glucose injection 500mL, iv drip, bid, for 5-7 days. Another 12 patients (including 4 patients with pelvic inflammatory disease and 8 patients with lower respiratory tract infection) were treated with Azithromycin as the op en group. Results: The treated group yielded a recovery ra te 61.7%, aeffective rate 91.5% and abacterial clearance rate 95.8%, which wer e higher than the controlled group [31.9%, 70.2%, and 76.6% (P＜0.01)]0,res pectively. The total response rate and the cure rate in 59 patients treated with Azithromycin were 93.2% and 62.7%, respectively. The incidence of clinical adve rse drug reactions in the treated group was 12.8%, being lower than 34.0% in the controlled group (P＜0.05). Conclusion: Azithromycin is an effective agent in the treatment of the acquired lower respiratory tract infection, urogenital and urogenital tract infection with slight adverse reaction .

BACKGROUND: Scholars disagree with each other about the small saphenous vein effects on skin flap and how to dispose vascular proximal pedicles.OBJECTIVE: To analyze effects of different methods of the small saphenous vein disposal on flap survival using sural neurocutaneous island flap retrograde metastasis for repairing defects of soft tissue of instep, heelstick and ankle.DESIGN, TIME AND SETTING: The case control observation experiment was performed at the General Hospital of Guangzhou Military Area Command of Chinese PLA from March 1998 to April 2007.PARTICIPANTS: A total of 56 patients with defects of soft tissue of instep, heelstick and ankle were divided into 2 groups,small sapbenous vein deligation in proximal pedicle flap group (group A) (n=38), and proximal small saphenous vein and great saphenous vein or tributaries at recipient site anastomosis flap group (group B) (n=18).METHODS: During sural neurocutaneous island flap retrograde metastasis for repair,(3.5×4.0)cm-(4.0×4.5) cm flap was obtained in 35 cases, and (4.0×4.5) cm -(10.0×12.0) cm in 21 cases.MAIN OUTCOME MEASURES: Outcome of flap survival at different incision area and implanted methods.RESULTS: No vein articulo occurred in 21 cases, which flap areas were (4.0×4.5) cm -(10.0×12.0) cm. Five of 35 cases which flap areas were (3.5×4.0) cm -(4.0×4.5) cm developed vein articulo.The necrotic rate of flaps in group B was significantly lower compared to the group A (P=0.017 67).CONCLUSION: When the area of skin flap is smaller than (4.0×4.5) cm, the proximal end of the small saphenous vein should be anastomosed with the great saphenous vein or tributaries connecting with the great saphenous vein at recipient site.The small saphenous vein is not a superficial vein, which only cross the skin flap, but it has trophic action on the skin flap.

BACKGROUND: Chronic rejection limits the long-term success of cardiac transplantation and the underlying causes of the disease are unknown. Connective tissue growth factor (CTGF) is considered as a mitogenic and chemotactic factor for fibroblasts and is associated with cell proliferation and collagen synthesis.OBJECTIVE: To evaluate the role and significance of expression of CTGF in rat chronic rejection heart aliografta.DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed at the Laboratory Animal Center of the Second Xiangya Hospital between April and August 2007.MATERIALS: Twenty Wistar rats serving as donors and twenty Sprague-Dawely (SD) rats serving as recipients were included. An additional 10 Wistar rats were included as controls.METHODS: After intra-abdominal heterotopic heart transplantations, rats received cyclosporine A, mycophenolate, and methylprednisolone immunosuppression. Ten recipient rats were anesthetized and sacrificed for heart harvesting at 2 and 8 weeks postoperation, respectively.MAIN OUTCOME MEASURES: Coronary vessel density, fibrosis grade, and intimal occlusion were observed by hematoxylin-cosin staining and Van Gieson staining. Myocardial fibrosis was semi-quantitatively scored. CTGF expression was detected by immunohistochemistry. The associations between CTGF expression and allograft fibrosis and CAV formation were analyzed.RESULTS: Allografts harvested at 8-week post-surgery showed more obvious coronary intimal proliferation, fibrosis and higher CTGF expression compared with the 2-week allografts and the controls (P < 0.05-0.01 ) while the cardiac artery density was lower than the control group (P < 0.05). However, the control group in our study showed negligible CTGF expression. There were strong negative correlations between the gray value of CTGF protein expression and cardiac fibrosis and coronary intimal occlusion (r = -0.734, -0.713, P < 0.01), demonstrating that CTGF protein expression was positively correlated with cardiac fibrosis and coronary intimal occlusion.CONCLUSION: CTGF is expressed in cardiac myocyte with CAV. The increased expression of CTGF in the cardiac allograft is associated with CAV development and fibrosis formation and is involved in the pathogenesis of cbronic heart rejection

Objective To detect the expression of connective tissue growth factor (CTGF) in acute heart allograft rejection in rats and to investigate the relationship between CTGF expression and cardiac allograft fibrosis. Methods Sixteen Wister rats served as donors and another 16 Sprague-Dawely (SD) rats served as recipients. Intra-abdominal heterotopic heart transplantation was performed. All rats received 10 mg/(kg·d) cyclosporine,40 mg/(kg·d)CellCept, and 3 mg/(kg·d)methylprednisolone immunosuppression after the surgery. Ten allografts were harvested 2 weeks postoperation while 10 normal Wister rats served as controls. The paraffin sections of harvested heart specimens were stained with hematoxylin and eosin (HE),and van Gieson(VG) for the examination of morphological changes to observe the lumen loss of myocardial coronary arteries and myocardial fibrosis. The expression of CTGF was studied by immunnohistochemical method and was measured semi quantitatively. The correlation between the CTGF expression and allograft fibrosis was studied. Results The allografts showed a typical symbol of acute rejection with excessive granulocyte infiltration around the vessel wall and myocardial interstice. There were also intimal proliferation and obvious fibrosis in the acute group and the differences between the acute and control group were significant (P<0.05). The expression of CTGF protein was mainly located around the vascular and myocardial lesions in the acute group while the control group showed no CTGF expression. The gray scale value of CTGF was (AR vs NH: 103.52±6.42 vs. 182.61±8.72,P<0.05). Strong negative correlations were found between the gray scale value and fibrosis formation(r=-0.734,P<0.01). Conclusion CTGF was overexpressed in acute allograft rejection rat hearts and might be involved in the pathogenesis of transplanted heart fibrosis.

Objective To study the therapeutic effects of extracorporeal shock wave therapy (ESWT) on temporomandibular joint disorders (TMDs).Methods Sixty patients with a temporomandibular joint disorder were randomly divided into an ESWT group and a control group,each of 30.Both groups were given routine rehabilitation training,but the treatment group additionally received ESWT for 2 weeks.Fricton's index was used to evaluate temporomandibular joint function.The subjects used a visual analogue scale (VAS) to evaluate their pain levels.The SF-36 scale was applied to assess their life quality.Results After two weeks of treatment,the average assessment score and VAS score had decreased significantly in both groups.After treatment the average scores for mandibular movement,muscle palpation,joint noise and joint palpation,and the palpation,dysfunction and craniomandibular indexes were all significantly lower in the ESWT group than in the control group.Significant differences were also found in the average VAS scores and on the social functioning domain of the SF-36 between the ESWT group and the control group.Conclusion ESWT combined with rehabilitation training can significantly relieve the symptoms and pain of TMDs.
