OBJECTIVE:To investigate the content of total sugar and polysaccharide in Radix et Rhizoma Rhei and its processed product in order to study the effect of different processing method on the content of total sugar and polysaccharide.METHODS:UV spectrophotometer was adopted to determine absorbance after the sulfuric acid-phenol coloration.The detection wavelength was set at 491 nm.RESULTS:The descending order of the content of total sugar and polysaccharide in Radix et Rhizoma Rhei and its processed product were as follow:prepared Radix et Rhizoma Rhei(steaming),prepared Radix et Rhizoma Rhei(processing with wine),Radix et Rhizoma Rhei,prepared Radix et Rhizoma Rhei with wine,prepared Radix et Rhizoma Rhei with vinegar and charred Radix et Rhizoma Rhei.CONCLUSION:The content of total sugar and polysaccharide in Radix et Rhizoma Rhei processed with different processing method were strikingly different from that of Radix et Rhizoma Rhei.The content of total sugar and polysaccharide in prepared Radix et Rhizoma Rhei were increased significantly while that of prepared Radix et Rhizoma Rhei with wine,prepared Radix et Rhizoma Rhei with vinegar and charred Radix et Rhizoma Rhei were decreased to some extent.

Unlike conventional radiation therapy, stereotactic radiation therapy (SRT) is an emerging tumor-ablative radiation technology with a high-dose delivery to targets while dramatically sparing adjacent normal tissues. The strengths of SRT involve noninvasive and short-course treatment, high rates of tumor local control with a low risk of side effects. Although the scientific concepts of radiobiology fail to be totally understood currently, SRT has shown its potential and advantages against various tumors, especially for those adjacent to less tolerable normal organs (spinal cord, optic nerve, bowels, etc.). Nowadays, the clinical efficacy of SRT has been widely confirmed in certain patients, especially for those medically inoperable, unwilling to undergo surgery, medicine ineffective with tumor progression. Moreover, SRT could be properly used as palliative treatment aiming at relieving local symptoms and pain, and eventually achieving a potential survival benefit of several months. However, the weaknesses of SRT relate to inevitable radiation-induced toxicities as well as the inaccessibility of prophylactic irradiation. In general, one flaw cannot obscure the splendor of the jade. The emergence and development of SRT has opened the new era of precision radiation therapy, and SRT will probably step gloriously onto the remarkable stage for precision medicine.

Objective To ascertain serum inflammatory markers could be modified following treatment of periodontal disease in elderly patients. Methods The probing depth (PD), clinical attachment level (AL), C-reactive protein (CRP), interleukin-6 (IL-6) were determined. And then fifty-two elderly periodontitis patients underwent a standard phase of non-surgical periodontitis treatment (consisting of oral hygiene instructions and subgingival scaling and root planning). After three and six months, PD, AL, CRP and IL-6 were determined again and compared to the baseline. Results Six months after treatment, significant reductions in PD [(5.9±1.1) mm vs. (6.8±1.0) mm, P＜0.05], AL [(1.3±0.9) mm vs.(8.4±1.1) mm, P＜0.05], CRP [(1.5±0.2) mg/L vs. (2.0±0.3) mg/L, P＜0.01] and IL-6 [(1.6±0.5) ng/L vs. (1.9±0.4) ng/L, P＜0.05] were observed. Conclusions Treatment of chronic periodontitis can decrease the levels of serum inflammatory markers in elderly patients.

Objective To evaluate the comprehensive experiment in fundamental nursing by using the indicator system and analyze the teaching effect.Methods 450 nursing graduates of grade 2011 were divided into 56 groups and comprehensive experiments were graded by using the indicator system in each group.Results The four indexes in level one scored (18.08±1.50),(19.99±2.31),(28.18±3.35),(18.16±1.73) points and accounted for 90％ 、80％ 、81％、91％ respectively.The total points' scorings and proportions were (84.41±5.84) points and 84％ respectively.Some deficiencies were found to be improved during evaluation.Conclusions Nursing comprehensive experiment evaluation indicator system can assess comprehensive experiments well,and the related competencies of nursing graduates need to be improved.

Objective:Surgery intervention and its effect on pregnancy heart disease were explored. Meth-ods:Retrospective review of 34 cases of pregnancy heart disease who needed surgery intervention from Jan, 2000 to Dec,2007 was done. Results:17 patients had percutaneous balloon mitral valve (PBMV) dilatation, the area of mitral valve enlarged markedly postoperatively ( P <0.01 ). 9 patients had open chest surgery un-der extracorpory circulation,7 of them had re-replacement mechanical valve due to mechanical valve throm-bosis. One patient had left atrium mucomamectomy. One patient had Wad's sinus breakout and repairmen. 5 patients had Radiofrequency catheter ablation (RFCA) for supraventricular tachycardia. 3 patients had int-racardiac device (ICD) for Ⅲ grade atrioventicular block. 22 patients had cardiac function as grade Ⅲ～Ⅳ and postoperatively recovered to grade Ⅰ～Ⅱ . All 34 patients were alive after treatment, 23 fetus were alive (67.6%), and no adverse results were found during the follow-up. Conclusions:When patients who had pregnancy heart disease need surgery intervention, individualized treatment plan should be made by multidis-cipline experienced doctors according to different heart disease and cardiac function.

The aim of this study was to figure out the predictors of early postoperative catheter-related bladder discomfort (CRBD) after urological surgery. We designed a prospective observational study in our hospital. Consecutive adult patients undergoing surgery under general anaesthesia or epidural anaesthesia necessitating urinary catheterization were included during a 3-month period. severity of bladder discomfort was assessed on a 4-point scale: (1) no pain, (2) mild pain (revealed only by interviewing the patient), (3) moderate (a spontaneous complaint by the patient of a burning sensation in the urethra and/or an urge to urinate and/or sensation of urethral foreign body without any emotional agitation) and (4) severe discomfort (agitation, loud complaints and attempt to remove the bladder catheter associated with a burning sensation in the urethra). Predictors of CRBD were identified by univariate and multivariate analysis. Totally, 116 patients were included, of which 84.5% had CRBD (mild CRBD: 40.5%; moderate or severe CRBD: 44.0%) at day 1, while 31.9% developed CRBD (mild CRBD: 29.3%; moderate or severe CRBD: 2.6%) at day 3. We evaluated 9 potential forecast factors of CRBD, and univariate Chi-square test showed male gender [OR=2.4, 95%CI (1.1-5.6), P<0.05], abdominal open surgery compared with transurethral surgery [OR=0.3, 95%CI (0.1-0.6), P<0.05], abdominal surgery compared with laparoscopic surgery [OR=3.3, 95%CI (1.2-8.9), P<0.05] and history of catheterization [OR=0.5, 95%CI (0.2-0.9), P<0.05] were independent predictors of moderate or severe CRBD in the patients after surgery. While multivariate logistic regression analysis showed that the abdominal open surgery [EXP(B)=3.074, 95%CI (1.3-7.4), P<0.05] and the history of catheterization [EXP(B)=2.458, 95%CI (1.1-5.9), P<0.05] might contribute more to the occurrence of moderate or severe CRBD. In conclusion, this observational study identified that the type of surgery and the history of catheterization might be predictive factors of moderate and severe CRBD after urological surgery.

Purpose To explore the role of histone H2B monoubiquitination in primary colonic carcinoma and clinicopathological pa-rameters of colonic carcinoma. Methods To detecte the expression of histone H2B monoubiquitination in 116 cases of primary colonic carcinoma and 15 cases of normal colonic mucosal tissue by avidin-biotin-peroxidase complex ( ABC)-immunohistochemistry. Results The level of histone H2B monoubiquitination was significantly reduced in poorly differentiated colonic carcinoma 19. 4% (6/31) compared with that of well-differentiated colonic carcinoma 49. 4%(42/85), moderately differentiated colonic carcinoma 49. 4% (42/85) and normal colonic mucosal tissue 86. 7% (13/15) (P<0. 05). The expression of histone H2B monoubiquitination was closely correlated with tumor differentiation, Dukes stage, TNM stage and lymph node metastasis (P<0. 05), but not depended on sex or age (P>0. 05). Conclusion Histone H2B monoubiquitination is obviously associated with the progression of primary colonic carcinoma. Although its specific mechanism still remains unclear, histone H2B monoubiquitination could be a novel potential molecular marker for early diagnosis, clinic treatment and prognosis evaluation.
