Objective To observe the therapeutic effect and security of Thermal Moxibustion combined with Yougui Pills in the treatment of premature ovary failure(POF) of spleen and kidney Yang-deficiency.Methods One hundred and forty-two patients with POF of spleen and kidney Yang-deficiency were randomly divided into the treatment group and control group,71 cases in each group.The observation group were treated with Thermal Moxibustion combined with Yougui Pills,while the control group took oral Yougui Pills,12 weeks as a course of treatment.After treatment,the clinical therapeutic effects,K upperman score,related hormones levels(E2,FSH,LH) and occurrence rate of adverse reactions were compared between the two groups.Results The total efficacy rate of the observation group was 95.77％,which of the control group was 77.46％,and the observation group was significantly better than the control group(P＜0.05);there were significant improvement in the Kupperman score and levels of related hormones after treatment in the two groups(P＜0.05),but the improvement degree of the observation group was superior to the control group(P＜0.05).Conclusion Thermal Moxibustion combined with Yougui Pills can alleviate the clinical symptoms with high safety and higher clinical application value

Objective To describe the structure and the level of the stress of nursing students in clinic practice,and supply reference for reform of clinical teaching method.Methods Totally 100 undergraduate nursing students in clinic practice,who would graduate from nursing school and begin to work in 2013,were interviewed and investigated.Results The main stress sources were divided into five aspects:recognition,clinical nursing ability,career development,field response and exhaustion of body and mind.Conclusions The structure and level of the stress of nursing students changed a lot.Some new appropriate reform should be introduced into clinic education,in order to help nursing students to complete psychological change and role adaptation.

This paper introduces double ultrasound pulse transmitting and receiving circuits used in ultrasound thermometry. Using the circuits, double ultrasound pulses could be made synchronously to satisfy the requirements of ultrasound thermometry, and the weak ultrasound echo signals are received successfully. The crux experiment waveform offered shows that the circuits have high reliability.

Objective To investigate the association of the polymorphism of the N-acetyltransferase 2 (NAT2 )gene with isoniazid-induced hepatotoxicity and anti-tuberculous treatment efficacy in Chinese Han patients with tuberculosis(TB).Methods A total of 108 TB patients who received initial anti-TB treatment were followed up prospectively.A polymerase chain reaction direct sequencing approach was used to detect genetic polymorphisms of the NAT2 gene.Associations between NAT2 genotype and isoniazid-induced hepatitis/early treatment were analyzed.Chi-square test was used for statistical analysis. Results Among the 108 TB patients, intermediate-acetylators (IA ) was the most frequent NAT2 genotype with the proportion of 54.63%(59/108).The proportion of rapid-acetylators(RA)was 33.33%(36/108),slow-acetylators (SA)was 10.19%(11/108)and super-rapid acetylators was 1 .85 % (2/108). Among the 20 patients who developed drug-induced hepatitis,2 were RA,5 were SA and 13 were IA. Regarding NAT2 genotype,RA patients had a lower incidence of hepatotoxicity (OR =0.176,95 %CI :0.038-0.809,P =0.014)and SA patients were more likely to developed drug-induced hepatic injury (OR=4.556,95 %CI :1 .231 -16.854,P =0.044 ).Statistical analysis revealed that the frequency of variant diplotypes,NAT2*4/*6A (OR=7.741 ,95 %CI :2.653-22.586,P <0.01 )and NAT2 *6A/*6A (OR=15 .353,95 %CI :1 .506 -156.552,P =0.020)were significantly increased in TB patients with hepatotoxicity.NAT2 *4/*4 was less likely to developed hepatic injury (OR =0.176,95 %CI :0.038-0.809,P =0.014).Among the 58 culture-positive patients,12(31 .03%)were persistent culture positive after 2 months standard therapy.Early treatment failure was observed with significantly higher incidence rate in RA than other genotypes (OR = 7.200, 95 % CI :1 .794-28.900, P = 0.008). Conclusions In Chinese Han TB patients,IA is the most frequent NAT2 genotype.The SA status of NAT2 is a risk factor of isoniazid-induced hepatotoxicity.The diplotype of NAT2 *6A has clearly high risk of isoniazid-induced hepatotoxicity.In contrast,NAT2 * 4/* 4 is protective diplotype.RA is associated with early treatment failure in culture-positive patients.

Objective To construct the recombinant plasmid pYES6-S and express and purify spike protein of severe acute respiratory syndrome(SANS)coronavirus in Saccharomyces cerevisiae. Methods DNA fragments of SANS coronavirus were obtained by reverse transeription.Four over- lapped fragments of spike protein genes were amplified by polymerase chain reaction(PCR)and ligated into an integral spike protein gene by restriction enzyme digestion.The spike protein gene recombined with pYES6 and cloned into E.coll.The recombinant plasmid pYES6-S was induced and expressed in Saccharomyces cerevisiae(INVScl)by galactose.Results The recombinant plasmid pYES6-S was confirmed that inserted fragment was right in length,direction and base matching by restriction enzyme digestion and sequencing.The purified protein encoded by the whole spike protein gene was about Mr 110?10~3 identified by electrophoresis.Conclusion The whole spike protein gene of SARS coronavirus is cloned into E.coli and the protein is expressed in Saccharomyces cerevisiae successful ly.which can be helpful in SARS vaccine research.

Background Chronic administration with inhibitor of nitric oxide synthase (N_?-nitro-L-arginine methyl ester,L-NAME) induces persistent hypertension,cardiovascular remodeling,surrounding vascular fibrosis, necrosis and hypertrophy of myocardium,and inflammation in cardiovascular system.Local RAS involves in hyper- tension and remodeling of cardiovascular system,via increasing production of oxygen free radicals (OFR).Objec- tive To elucidate the preventive and therapeutic effect of antioxidant Ebselen and/or VitE on hypertensive heart damage in NO~- deficient rats induced by L-NAME.Methods Thirty-two Wistar rats were administered with L- NAME 50 mg/(kg?d) by gavage for 8 weeks,and randomized to received a placebo(L),or Ebs(S,30 mg/kg?d), or VitE(V,40 mg/kg?d) or Ebs 30 mg/(kg?d)+VitE 40 mg/(kg?d),with 8 normal Wistar as control. Body mass and SBP were measured fortnightly.Plasma and homogenate of heart were collected for NO,Ang Ⅱ, GSH-PX,MDA and O_2~- determination.Results Eight weeks after L-NAME administration,SBP in experimental groups was obviously higher than that of control (P

Objective:Establish mass-scale purification technology of cell-derived influenza virus. Methods: A microcarrier-based process was used to produce human influenza virus in serum free-adapted Vero cells. The virus was purified in a sequence of downstream processing steps including inactivation, clarification, anion exchange chromatography, affinity chromatography and size-exclusion chromatography. Results: The recovery of HA reached 102%. 95.3% total protein, including 99.77% host cell protein, and 99.99% host cell DNA were removed during downstream processing. Conclusion: Providing a high effective purification technology for cell-derived influenza virus.

Objective To investigate quantitatively the thermal sensation characteristics of the patients with facial palsy and the value of quantitative thermal test (QTT) in prognostication.Methods The QTT threshold of the fore ear and cheek of 30 patients with peripheral facial palsy was tested,their facial nerve conduction velocity was measured,and House-Brackmann facial nerve grading system was used to estimate facial nerve function at 2～3 weeks,a month,two months and half a year post onset.Results It was found that 12 out of 30 patients had abnor- mal QTT threshold value;the majority of them suffered from herpes virus and diabetes.In those with abnormal QTT, 8 were with diabetes mellitus (account for 66.7%),3 with partial shingles (account for 25%),and 1 with positive serum virus infection (account for 8.3%).Those with normal QTT were significantly different from those with abnor- mal QTT,with regard to the House-Brackmann rating scores after 2 and 6 months post onset (P
