Objective To explore the best fat liquefaction prevention measures for gynecological obese patients with abdominal incision.Methods 84 gynecological obese patients with abdominal incision were divided into the observation group(46 cases)and control group(38 cases),according to the negative pressure attract ball placed or not in the subcutaneous fat layer during operation.Patients in both groups were taken abdominal incision physiotherapy.Results The fat liquefaction rate of the observation group was 8.7％,which was lower than that of the control group(26.3％)(x2=4.65,P＜0.05).Conclusion It is very important to keep the incision dry,smooth drainage for prevention and treatment of fat liquefaction in gynecological obese patients after abdominal incision.

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.

Purpose To observe the action time of parthenolide (PTN) as selective nuclear factor-κB(NF-κB) inhibitor in heart of rats.Methods Forty SD rats were randomly divided into control(CON) group,PTN group,dimethyl sulfoxide(DMSO) group,lipopolysaccharide(LPS) group and PTN+LPS group.The first day:PTN group,DMSO group and PTN+LPS group rats were respectively injected interapertoneally PTN(500 μg/kg) and DMSO; other groups rats were injected interapertoneally equivalent saline.The second day(in equivalent to 24 h after injecting PTN):in LPS group and PTN+LPS group LPS(12.5 mg/kg) was administered subcutaneously; other group rats were injected subcutaneously equivalent saline.Every heart was obtained in equivalentce to 1 h after injecting LPS to measure the expression of NF-κB p50 in nucleus,inhibitory kappaB(IκBα) and phosphorylation inhibitory kappaB(p-IκBα) in cytoplasm of cardiac myocytes through Western blotting.Results Compared with CON group,the expression of NF-κB p50,IκBα and p-IκBα had no difference in PTN and DMSO group.And in LPS group and PTN + LPS group,the expression of NF-κB p50 up-regulated significantly(P＜0.05),IκBα down-regulated(P＜0.05) and p-IκBα up-regulated significantly(P＜0.05).Conclusion LPS can activate NF-κB in 1 h and PTN in rats after 24 h has few effect.

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.

Objective To evaluate the benefits and potential adverse effects of Cordyceps sinensis as an adjuvant immunosuppressive treatment in acute kidney injury.Methods English language database ( including MEDLINE, EMBASE and CENTRAL) in systematic review searched, using search terms relevant to this review.Chinese language databases ( including CNKI, CBM, WanFang and other resources) in systematic review also searched.It included all randomised controlled trials ( RCTs) and quasi-RCTs evaluating the benefits and potential side effects of Cordyceps sinensis for acute kidney injury, irrespective of blinding or publication language.An inclusion criterion was that immunosuppressive therapy baseline must be the same across arms in each study.Data were collected and analyzed by RevMan 5.0.Methodological risk of bias was assessed using the Cochrane risk of bias tool. Results This review included 7 RCTs (representing a total of 601 patients with acute kidney injury) that assessed the use of Cordyceps.Reporting of methods was incomplete in most studies.It conducted comparisons of Cordyceps versus no treatments on the base of same conventional treatment in both groups.Cordyceps for patients showed a favorable trends toward improving patient survival and reducing renal replace treatment, but the difference did not reach significance.However, Cordyceps significantly reduce the level of serum creatinine shorten the period of oliguria, and increase the osmotic pressure of urine.Conclusion On the base of same conventional treatment in both groups, compared with no treatment, Cordyceps significantly improves the functions of renal tubule and glomerulus.But long-term studies are needed to clarify any benefit-harm trade-off.Future studies also need to be appropriately sized and powered.
