Objective To compare the efficacy of laparoscopic appendectomy(LA) and open appendectomy(OA) for perforated appendicitis.Methods From January 2002 to December 2005,40 patients with perforated appendicitis were treated at Xuanwu Hospital,20 of them received LA,and the others underwent OA.The clinical data of the patients were retrospectively analyzed.Results The operative time in the LA group was significantly longer than that in the OA group [(75.8?11.6) min vs(54.8?9.5) min,t=6.264,P=0.000)].And the patients in the LA group returned to oral intake earlier than those in the OA group [(1.8?0.5) d vs(2.6?0.5) d,t=-5.060,P=0.000].Moreover,the periods of antibiotic use and hospital stay in the LA group were significantly shorter than those in the OA group [(3.8?0.7) d vs(6.3?1.2) d,t=-8.048,P=0.000;and(5.8?1.1) d vs(11.6?1.6) d,t=-13.359,P=0.000].Although 3 patients had incision infection in the OA group,while none of the LA group had such a complication,no significant difference was detected in the complication rate between the two groups(Fisher's exact test,P=0.115).Conclusions Laparoscopic appendectomy is superior to open surgery for perforated appendicitis because of its advantages of quick recovery,short hospitalization,less antibiotic use,and minimal invasion.LA is a safe,effective,and feasible procedure for perforated appendicitis.

Objective To measure the mandibular thickness relative to the osteotomy line of mandibular angle plasty so that to provide the anatomical basis for operation.Methods 37 youth women patients mandible were scanned by spiral CT,then the three-dimensional reconstruction was done,the thickness of the mandible around osteotomy line were measured on the planes corresponding to the posterior margin of mandibukar ramus,the middle part of the mandibular ramus,the posterior line of the third molar,the line between the second and third molar,the line between the second and first molar and the line between the first molar and the second premolar.The data were analyzed by Spss 11.5.Results The thichest bone around the osteotomy line was under the second and third molar,then the bone thickness became thinner forward and backward.The thinnest bony was on the middle part of the mandibular ramus.Conclusion The result of this study is of significant for guiding operation and reducing the complications.

Objective To explore the effect of psychological rehabilitation on patients with limb motor dysfunction. Methods 136 cases of hospitalized patients who needed rehabilitation therapy and training were divided into observation group and control group. The control group received conventional rehabilitation, and the observation group received psychological rehabilitation (psychotherapy and medicine) in addition. Symptom Checklist-90 (SCL-90), Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) were assessed before and 8 weeks after treatment. Results Most of the 136 patients were involved in psychological problems, including anxiety, depression, somatization,fear, hostility. There was no difference in the scores of SCL-90, FMA and MBI between 2 groups before treatment (P>0.05). After 8 weeks treatment, the scores of SCL-90 were lower, except psychotism (P>0.05), in the observation group than in the control group (P<0.05),the scores of FMA and MBI were higher in the observation group than in the control group (P<0.01). Conclusion The psychological rehabilitation plays an important role in rehabilitation of limb motor dysfunction.

Background and purpose:Icariin (ICA) is the important active flavonoids extracted from Berberidaceaeepimedium. It has been shown to be effective in suppressing cancers including lung cancer and gastric cancer. Thus, it is expected to be developed for cancer treatment. However, there were few studies on icariin as a promising anticancer drug for the treatment of thyroid cancer. The mechanisms underlying anticancer effects of ICA in thyroid cancer are rarely reported. This study was to explore the proliferation and apoptosis, intracellular ROS and antioxidant enzyme systems of the thyroid carcinoma cell line B-CPAP treated with different concentrations of ICA. It aimed to explore the mechanism underlying anticancer effects of ICA, and to determine whether it is concentration- or time-dependent manner.Methods:The proliferation of B-CPAP cell line treated with different concentrations of ICA was detected by cell counting kit-8 (CCK-8). The cell apoptosis and intracellular ROS were observed by flow cytometry. The expression of intracellular superoxide dismutase and intracellular malondialdehyde were measured by SOD detection kit and MDA assay kit, respectively. Bcl-2 and γ-HA2X were detected by Western blot.Results:ICA reduced B-CPAP cell activity, increased the rate of apoptosis in a dose- and time-dependent manner after 48 h (P<0.01). The ROS of ICA 50 mg/L and 200 mg/L groups were (2.12±0.14)-fold and (2.41±0.12)-fold of the control group, respectively. ICA promoted accumulation of malondialdehyde, and reduced antioxidant enzyme SOD activity. The SOD activity was decreased by (9.35±1.45)% (ICA 50 mg/L group) and (21.5±1.52)% (ICA 200 mg/L group) compared with the control group, respectively. The anti-apoptotic protein Bcl-2 in ICA 200 mg/L group was decreased by (13.64±1.71)%compared with the control group.Conclusion:Icariin inhibited activity of thyroid cancer B-CPAP cells in a dose- and time-dependent manner. It plays an important role in promoting intracellular ROS expression, inhibiting superoxide dismutase expression and decreasing Bcl-2, which leads to irreversible damage to the cell, thereby inducing apoptosis.

Objective To investigate the clinical efficacy ofβ-lactam combined with macrolides antibiotics in treatment of severe community-acquired pneumonia (CAP) in children. Methods Children with severe CAP on admission between 2012 February and 2012 April were divided into treatment group and control group. With the same symptom specific supportive treat-ment, the patients in the treatment group were treated with both cefmetazole and azithromycin, while the patients in the control group were treated with cefmetazole alone. The total effective rate, number of days of symptoms and signs disappeared and num-ber of days of hospitalization were observed. Results The total effective rate was 87.8%in the trearment group and 61.3%in the control group with significant difference (P<0.05). Compared with control group, the recovery time of temperature, time of pulmonary rale disappearing and cough retraction were reduced (P<0.05). As well as the number of days of hospitalization was decreased (P<0.05). Conclusions The treatment of severe CAP in children with combination of azithromycin and cefmetazole results in better curative effect. A combined medication ofβ-lactam and macrolides antibiotics may be rational and effective.

Objective: To compare the selective splenic artery embolization (SSAE) with non-operative therapy of traumatic splenic rupture (TSR). Methods: The clinical data of 23 patients with TSR receiving SSAE and 32 undergoing non-operative therapy between 1992 and 2006 in our hospital were retrospectively analyzed. Results: There was no blood transfusion in SSAE group, and one patient was received it in the non-operative therapy group. Two patients in SSAE group had complications with left pleural effusion, and one had left pulmonary infection. One patient with non-operative therapy complicated with spleen abscess (P=0.298). The ratio of successful management in SSAE and non-operative group were 100% (23/23) and 81.3% (26/32) respectively(P=0.035). All the patients in both groups were survival. The mean hospital days in non-operative group(11.9?4.6) were significantly longer than that in SSAE group(7.9?2.1, P=0.045). Conclusions: Splenic injuries with grade Ⅰor Ⅱ are suitable for preserving spleen management. SSAE may be more safe and effective than non-operative therapy.
