Objective:To observe the clinical effect of self-prescribed Zuoyu No. 2 (ZY2) in the treatment of anal eczema after complex anal fistula operation. Methods: Totally 100 patients were randomly divided into two groups, the patients in the treatment group were given ZY2 combined with the conventional wound dressing treatment after defecation everyday, while the patients in the con-trol group were treated with washing infection area with warm water followed by applying triamcinolone acetonide and econazole creams on the lesion or itching skin combined with the conventional wound dressing after defecation everyday. Results:The efficiency rate in the treatment group was higher than that in the control group (82. 0% vs 60. 0%, P<0. 05), the total effective rate in the treatment group was also significantly higher than that in the control group (100% vs 90. 0%, P<0. 05). The anal pruritus disappearance time and the skin lesion recovery time in the treatment group were better than those in the control group(P<0. 05). Conclusion:ZY2 has a good clinical curative efficacy in the treatment of anal eczema after complex anal fistula operation with improvement of clinical symp-toms, which is worthy of promoted application.

Objective:To observe the clinical effects of Zuoyu üo. 1(ZY1)in the prevention of concomitant concurrent complica-tions after operation for anorectal diseases. Methods:164 patients who had received operation for anorectal diseases were randomly di-vided into 2 groups. Patients in the treatment group were treated with sitz baths in ZY1 and the conventional wound dressing method. Patients in the control group were treated with sitz baths in warm water and the conventional wound dressing method. Results:The effi-ciency rate of the treatment group was significantly higher than that of the control group(53. 57% vs. 27. 5%,P<0. 05),as well as the total effectiveness(95. 23% vs. 88. 75%,P<0. 05). The comparison showed that better curative effects existed in the treatment group on distress,bleeding,and edema ratings and wound healing time. Conclusion:Sitz bath in ZY1 after operation for anorectal dis-eases reduces complications and shortens the wound healing time without any side effect. It is thus extensively promising in clinical ap-plications.

Based on the needs of healthcare system reform, Australia has implemented activity based funding(ABF) payment mode nationwide, and established the Independent Hospital Pricing Authority as the specific implementation agency in 2011. The main responsibilities and functions of the ABF payment mode covers pricing of medical services, classification of healthcare services, collection of clinical data and cost accounting of healthcare services. ABF payment mode presents outstanding advantages in promoting the capacity of healthcare service, maintaining fairness of healthcare service supplies and carrying out cooperation across different institutions. These efforts provide important references for China in its top-level design of payment method, pilot project of classification system, medical service items and price dynamic adjustment, informationization and information standardization construction among public hospitals.

Objective:To explore the independent prognostic factors of primary osteosarcoma patients under 20 years old after radical surgery, so as to predict the prognosis and survival of patients.Methods:The clinicopathological data of 1 339 patients with primary osteosarcoma diagnosed and registered in the National Cancer Institute Surveillance, epidemiology and outcome database (SEER) from 1984 to 2014 were retrospectively analyzed. Kaplan Meier method was used to calculate the survival rate of patients. Log rank test was used to evaluate the survival difference. Cox multivariate analysis was used to determine the independent prognostic factors of osteosarcoma after radical surgery factor.Results:The results of primary osteosarcoma patients undergoing radical surgery found that 34 cases (2.54%) aged 0-5 years old, 236 cases (17.63%) aged 6-10 years old, and 600 cases (44.81%) aged 11-15 years old and 469 cases (35.02%) aged 16-20 years old. The median survival time was 68 months. Among them, 757(56.53%) were male and 582(43.47%) were female. Among the 1 339 cases, 986 were white (73.64%), followed by black 230(17.18%), and 123 other races (9.18%). Multivariate analysis revealed that males ( HR=1.242; 95% CI:1.024-1.505), axial osteosarcoma ( HR=1.589; 95% CI:1.179-2.166), and regional invasion of osteosarcoma ( HR=1.470; 95% CI:1.156-1.870), distant metastasis ( HR=3.536; 95% CI:2.725-4.589) were independent risk factors for overall survival. Other types of osteosarcoma ( HR=0.471; 95% CI:0.285-0.779) were independent protective factors for overall survival. Conclusions:Based on the SEER database, this study identified independent prognostic factors for patients with primary osteosarcoma under the age of 20 who underwent radical surgery, which will help clinicians formulate individualized medical strategies and predict patients′ prognosis.

OBJECTIVETo compare the efficacy of internal fixation (including PFNA and PFN) versus hip replacement (including FHR or THA) in the treatment of trochanteric fractures in adults.

METHODSReports of studies using randomized controlled trials (RCT) to compare internal fixationg with hip replacement in the management of intertrochanteric fractures were retrieved (up to January 1, 2013) from the Cochrane Library, PUBMED Data, CNKI (China National Knowledge infrastructure), Elsevier, the Chinese Biomedical Database, Wanfang Data, and manually. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software RevMan 5.0 was used for data-analysis.

RESULTSSeven articles were included in the meta-analysis. The results showed that,compared internal fixation with hip replacement,there were statistical significance in the duration of surgery time [WMD = -2.66, 95% CI (-5.25,-0.06), P = 0.05], intra-operative blood loss [WMD = -24.20, 95% CI (-30.38, -18.02), P < 0.000 01], hospital stays time [WMD = -4.72, 95% CI (-5.18, -4.25), P < 0.000 01], bearing load time [WMD = -29.54, 95% CI (-30.77, -28.31), P < 0.000 01], total complications rate [WMD = 0.15, 95% CI (0.11, 0.22), P < 0.000 01], the good rate of Harris scores [WMD = 1.09, 95% CI (0.54,1.32), P < 0.05]. However, there were no statistical significance in the rate of deep venous thrombosis [WMD = 1.09, 95% CI (0.47, 2.55), P > 0.05]. CON- CLUSION: Hip replacement (containing FHR or THA) for the treatment of intertrochanteric fractures is superior to internal fixa- tion in regards to the duration of surgery time, the mean duration of hosipital stays, mean post-operative down time, intra-opera- tive blood loss, the rate of post-operative good Harris scores. But there is not enough evidence to show any difference between hip replacement (containing THA or FHR) and internal fixation in regards to the rate of deep venous thrombosis. However, internal fixation for the treatment of intertrochanteric fractures is superior to hip replacement (containing FHR or THA) in regards to total complications rate.

The kinetics of nicotine degradation by O.intermedium DN2 and its application in tobacco waste were investigated. The results showed that the optimum temperature of nicotine degradation by O.intermedium was 30 ℃, the pH value was 6.5 and a mount of inoculum was 5 %. Under above conditions, the kinetics of nicotine degradation of initial concentration 500 mg/L was studied. The results indicated that the degradation process of nicotine with no-induced strain DN2 followed inverse S-shaped curve, and degradation process of nicotine with induced cells of DN2 followed Eckenfelder mode. The half life of nicotine degradation was 17.43 h and 4.10 h, respectively. And the results also showed that tolerance of O.intermedium DN2 to nicotine was up to 5000 mg/L when 0.1 % of glucose was added. Nicotine (2 220 mg/L) in extract of tobacco wastes degraded about 95.22 % by strain DN2 in 60 h incubation, indicating that strain DN2 was of application value in treatment nicotine pollution.

To improve 3-ketosteroid-△1-dehydrogenase(KSDH) activity and the transformation level for androst-4-ene-3,17-dione, 3-ketosteroid-△1-dehydrogenase gene(ksdD) from Arthrobacter simplex was cloned into plasmid pWB980 and expressed in B. subtilis WB600 under the control of promoter P43. The molecular weight of expressed enzyme was about 55kDa by SDS-PAGE analysis. The activitities assayed by spectrophotometrical method of intracellular and extracellular soluble enzyme were 110?0.5mU and 15?0.6mU per milligram of protein respectively. The transformation rate of androst-4-ene-3,17-dione by the B. subtilis recombinant cells was 45.3%. Compared with Arthrobacter simplex, the enzyme activity of KSDH expressed in B. subtilis was improved about 30 fold, and the transformation level of androst-4-ene-3,17-dione by the B. subtilis recombinant cells was improved about 10 fold. The recombinant B. subtilis cells used in biotransformation of steroids provided a new way for steroid medicines production.

Pharmaceutical market is a typical market with information asymmetry, and which can lead to "lemons" problem. In all developed countries, firms must receive regulatory approval to market a pharmaceutical product. Such administrative department including SFDA, EMA, FDA and so on. Chinese materia medica is a special part of pharmaceutical market in China. The management of Chinese materia medica is a special challenge in China.

ObjectiveTo explore the value of conventional echocardiography and transthoracic real-time three-dimensional echocardiography (RT3DE) in diagnosis of Ebstein anomaly.MethodsWe investigated the morphology and function of right ventricle (RV) as well as the structure, morphology and regurgitation of tricuspid valve in 61 adult patients with Ebstein anomaly before surgery by using conventional echocardiography and transthoracic RT3DE. Twenty normal adults were enrolled as control group. ResultsThe surface of the tricuspid leaflets, the morphology of the tricuspid annulus as well as the three-dimensional structure of the tricuspid valve were displayed stereoscopically by RT3DE. Complete RV volume data could be acquired in 32 patients of Ebstein anomaly. The apex or part of RV could not be contained in the remaining 29 patients. Thirty-four (55.7%) patients with Ebstein anomaly had severe tricuspid regurgitation,
16 (26.2%) patients had moderate to severe regurgitation, and 11 (18.1%) patients had moderate regurgitation. Compared with the normal adults, patients of Ebstein anomaly showed higher RV end-diastolic volume (EDV), end-systolic volume (ESV), end-diastolic volume index (EDVI), end-systolic volume index (ESVI), stroke volume (SV), RV anterior-posterior diameter (RV), tricuspid valve annular transverse diameter (TV-R), and lower RV ejection fraction(EF) [(273.5±77.7) mlvs (74.3±15.9) ml, (187.1±96.8) mlvs (31.1±9.2) ml, (177.4±53.6) ml/m2vs (43.4±8.2) ml/m2, (121.7±65.5) ml/m2vs (18.4±5.1) ml/m2, (95.9±20.2) ml vs (43.6±8.8) ml, (48.1±13.3) ml/m2vs (19.0±1.9) ml/m2, (56.4±8.9) ml/m2vs (28.5±4.3) ml/m2, (38.3±12.8) %vs (59.3±5.1) %, allP<0.05). The tricuspid regurgitant orifice flow cross-sectional area (EROA) were correlated positively with RV anterior-posterior diameter (r=0.691), ratio of RV and LV anterior-posterior diameter (RV/LV) (r=0.6471).ConclusionTransthoracic RT3DE is a feasible method in addition to conventional two-dimensional echocardiography in evaluation of tricuspid valve mophology and function, as well as RV volume and EF in adult patients with Ebstein anomaly.
