Objective To evaluate the inhibitory effects of NF-κB inhibitor pyrrolidine dithiocar-bamate (PDTC) on NF-kappa B activity and the serum inflammatory mediators in hypertensive-ventricular hypertrophy-congestive heart fail?ure rats. Methods The rat model of hypertension-cardiac hypertrophy-heart failure was made from 42 male Dahl salt sen?sitive rats. Rats were randomly divided into seven groups including group A (normal diet group), group B (high salt diet group), group C (NF-κB inhibition in early stage), group D (NF-κB inhibition in hypertensive stage), group E (NF-κB inhibi?tion in cardiac hypertrophy stage of week 12) and group G (NF-κB inhibition in heart failure stage). There were six rats for each group. Rats were administrated 8%high salt diet and injected PDTC 100 mg/(kg·d)intraperitoneally according to the prescribed time. Changes of blood pressure, left ventricular end diastolic interventricular septal thickness (IVSD), left ven?tricular end diastolic posterior wall thickness (LVPWD), left ventricular end diastolic diameter (LVEDD), systolic left ventric?ular end diastolic diameter (LVESD), left ventricular ejection fraction (LVEF), heart, lung weight/ body weight ratio, NF-kappa B activity, tumor necrosis factor (TNF)-α, interleukin (IL)-6, monocyte chemotactic protein (MCP)-1 and C-reactive protein (CRP) were observed in different treatment time points of PDCT. Results Levels of NF-κB and proinflammatory cy?tokines were reduced after early administration of PDTC, and the cardiac function was also decreased. The longer the treat?ment time, the greater the protective effect on heart. PDTC can effectively control blood pressure, and block left ventricular hypertrophy and left ventricular failure in a certain extent. The effects of PDTC were limited after persistent hypertension, and myocardial hypertrophy formation accompanied by heart failure. Conclusion PDTC plays a role in prevention and treatment of hypertension, left ventricular hypertrophy and congestive heart failure in model rats. Early application of PDTC could obviously maintain the normal cardiac function in rats with heart disease.

ObjectiveTo investigate the clinical effect and possible mechanism of modified Shenling Baizhu Powder （参苓白术散） and Xiaoluo Pill （消瘰丸） in the treatment of children with adenoid hypertrophy due to spleen deficiency and phlegm accumulation. MethodsOne hundred and thirty children with adenoid hyperplasia due to spleen deficiency and phlegm accumulation were randomly divided into 65 cases each in the observation group and control group. The control group was given mometasone furoate nasal spray， one spray into each nostril， once a day， while the observation group was given modified Shenling Baizhu Powder and Xiaoluo Pill orally， one dose per day， and both groups were treated for 8 months. The pre- and after-treatment electronic nasopharyngoscope scores， specific quality of life survey scale （OSA-18） scores， total TCM symptom scores， serum cysteine leukotrienes （CysLTs）， interleukin 2 （IL-2）， tumor necrosis factor α （TNF-α）， and interleukin 10 （IL-10） levels were compared to determine the clinical efficacy after treatment. ResultsAfter treatment， the electronic nasopharyngoscope scores， OSA-18 scores， total TCM symptom scores， serum CysLTs， IL-2 and TNF-α levels significantly decreased， while IL-10 levels increased in both groups （P＜0.01）. Compared between the two groups after treatment， the electronic nasopharyngoscope score， OSA-18 score， total TCM symptom score， serum CysLTs， IL-2 and TNF-α levels were significantly lower， and the IL-10 level was higher in the observation group than in the control group （P＜0.01）. The total effective rate of the observation group was 95.38% （62/65）， superior to 81.54% （53/65） of the control group （P＜0.05）. ConclusionFor children with adenoid hypertrophy due to spleen deficiency and phlegm accumulation， modified Shenling Baizhu Powder and Xiaoluo Pill can help to improve symptoms， increase quality of life and clinical efficacy， and its mechanism may be related to reducing the inflammatory response.

Objective To conduct a preliminary study on the efficacy and mechanism of Chinese traditional medicine Zeguilongshuang capsule for benign prostatic hyperplasia (BPH). Methods 20 patients with BPH were randomized into treatment group and control group (10 patients in each group).The medical history,International Prostate Symptom Score (IPSS),digital rectal examination,ultrasonography and uroflowmetry were done at the baseline.Patients in the treatment group used two Zeguilongshuang capsules three times per day for one month with repeated IPSS and above-mentioned examinations. They underwent prostatectomy on the next day when the treatment was completed.Patients in the control group received prostatectomy directly. After the pathological diagnosis of BPH was made,the expression of basic fibroblast growth factor (bFGF),platelet-derived growth factor (PDGF) and androgen receptor (AR) in the BPH tissue were assessed by immunohistochemistry. Results Patients in the treatment group reported improvement of low urinary tract symptoms, the mean IPSS decreased by 11.2%,the mean volume of the prostate reduced by 16.7%,and the mean maximum flow rate increased by 35.6%.Compared with the control group,the expression of bFGF in BPH tissue was down regulated ( P

Objective To study the serum levels of homocysteine(Hcy) and the polymorphism of C677T mutation of methylenetetrahydrofolate reductase (MTHFR) gene in pregnant women to explore their role in the pathogenesis of pre-clampsia. Methods Fifty pregnant women with preclampsia (study group) including 14 mild pre-eclampsia and 36 severe pre-eclampsia and 40 healthy ones (control group) were selected. Hey concentration was determined by fluorescence polarization immunoassay. The mutations of the 677C→T and 1298A→C of MTHFR were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The mean level of plasma Hey in the study group was higher than that of control 1(12. 00±4. 59) μmol/L vs (7. 85:1:1.51) μmol/L, P<0.05], and that of the severe pre-eclampsia group was higher E(13. 30±2. 06) μmol/L, P<0. 01]. However, no significant difference was found between the control and the mild pre-clampsia group[(8. 63±3. 94) μmol/L, P>0.05]. There was significant difference in the genotype frequencies of MTHFR 677CT, TT genotype(C/T:42.0% ;T/T:14. 0%)and the total frequency of mutant T (T: 35.0%) allele between the study and control groups (P < 0. 05). Conclusions Hyperhomocysteinemia plays an important role in the pathogenesis of pre-clampsia. The polymorphism of MTHFR C677T might be associated with the development of pre-clampsia as it affects the metabolism of Hey.

OBJECTIVE: To analyze the effects of social and psychological factors on rehabilitation status of end stage renal disease (ESRD) patients under peritoneal dialysis. METHODS: From August in 2005 to March in 2007, 171 patients experienced peritoneal dialysis were diagnosed at the Center of Peritoneal Dialysis, Department of Nephrology, First Hospital, Peking University, including 66 males and 105 females, aged (60±13) years, with an average dialysis time of 22.8 months. They were studied with questionnaires and interview. Rehabilitation status was investigated from two aspects of activity and participation by Karnofsky activity index, Social Dysfunction Screening Scale. Hamilton depression and anxiety scales, Medical Coping Modes Questionnaire and Social Supporting Rating Scale were used to investigate social and psychological factors.RESULTS: A total of 200 questionnaires were handed out and 171 (85.5%) of them were drawn in. 134 patient had normal activity status, 78.4% of them had Dysfunction and 129 patients (75.4%) had normal social function status. Forty-two (24.5%) of patients had the symptom of anxiety, 15 (8.2%) had depression. The score of "Acceptance-Resignation" was significantly higher in this group than patients with other chronic diseases. There were no significant differences in scores of "Confrontation" and "Avoidance". Activity of rehabilitation outcome and participation index served as dependent variable, whereas depression and anxiety, coping mode and social supporting as independent variable. Using multiple stepwise regression analysis, factors that affected patient rehabilitation were found, including depression, utilization of social support and the facing coping mode. CONCLUSION: Depression, utilization of social support and the facing coping mode have important effects on patient rehabilitation.

BACKGROUND: Xenograft cortical bone is an easy and inexpensive bone graft material, which has good biocompatibility and bio-mechanical properties. As a bone graft, it can function as biological framework for new bone growth and bio-supporting. Moreover, it can also be processed into internal fixation devices.OBJECTIVE: To review the biological properties, preparation methods and clinical applications of heterogeneous cortical bone for fracture fixation.METHODS: A computer-based online search of Pubmed database (1990-01/2009-05) and CNKI (1990-01/2009-05) was performed for related articles with key words of "Xenograft cortical bone, Bone graft, Fixation" in English and Chinese.RESULTS AND CONCLUSION: A total of 128 articles were collected. Xenograft cortical bone has a good biological performance, in particular, a certain degree of bio-mechanical properties. It is not only able to complete bone filling, bone induction, but also function as internal fixator following processing. However, the traditional preparation process reduces their bio-mechanical properties. Heterogeneous cortical bone can be widely used in intra-articular fractures and cancellous bone fracture fixation, and can be self-absorbed, avoiding the second operation. However, its instability limits its initial mechanical properties of fractures at other sites.
