Background Hypertension is a multigenetic inheritable disease.Gene therapy by regulating gene expression showed long term effects and less side effects,and has been emerged to be a potential and prospective treatment.Objective To investigate the effects of retroviraladeno-associated virus vector containing shRNA targeted on the AT1R gene (rAAV-AT1R-shRNA) on blood preesure(BP) in renal hypertensive rats,and the inhibitory effect of RNA interference (RNAi) on AT1R mRNA expression in renal hypertensive rats.Methods Two-kideny one-clip (2K1C) renal hypertension (RH) were established in SD rats and randomly to receive rAAV-AT1R-shRNA,1.5?109 particles/mL(n=12,ip),as treated group or retroviral vector (rAAV-EGFP),2.9?109 particles/mL,ip,as vehicle group,normal SD rats served as controls (n=12).SBP was measured before and after treatment.Animals were euthanized and blood,brain,heart,liver,kidney,aorta and adrenal gland were collected to identify the sites of rAAV-AT1R-shRNA expression by fluorescence microscope.Angiotensin Ⅱwas assessed by radioimmunology.Results 24 hours after single injection of rAAV-AT1R-shRNA,SBP was reduced by (22.3?5.5)mmHg compared to before intervention (P

Objective To explore the mental health status of physical examination population,and provide the basis for mental health guidance.Methods The SCL-90 scale in the cloud service system of PEM was used to evaluate the gender, marriage, age, education, income and other factors in the physical examination cases of our hospital.Results The positive rate of SCL-90 in 809 patients was 27.94%.Female scores,and the scores of somatization, obsessive-compulsive symptoms, depression, anxiety, terror of women were higher than those of men except paranoid.Unmarried population scores and the scores of all factors were higher than those of married and divorced people.The scores of all factors in the 18-<30 year-old cases was the highest among all cases;the scores of depression,hostility and paranoid was decreased with the increase of age;the score of somatization, obsessive-compulsive symptoms, interpersonal sensitivity, anxiety, terror,spirit of 50-60 year-old cases were the lowest among all cases.The higher the degree of education,and the more economic income, the lower the psychological evaluation of each factors scored.Conclusion The mental health problems of female,unmarried,low age,low education,low-income groups are grim.

OBJECTIVE:To improve medication safety and efficacy.METHODS:5different tablets broken off with hands were investigated with respect to weight variations and microbial limits by reference to Chinese Pharmacopeia.RESULTS:The5kinds of tablets broken off with hands were not in conformity with Chinese Pharmacopeia with respect to weight variation and which involved different degrees of microbial contaminations.CONCLUSION:It is recommended that pharmaceutical enter?prises should add more dosage forms of standard drugs that suitable for the use of children,women,the aged and particular patients.If the separately packaged drugs must be broken off with hands,aseptic method should be applied in which the drugs were broken off by the pharmacists on the sterile air bench before being separately packed with sterilized plastic pouches(which were sterilized with anprolene),and which should be administered to the patients for taking during the same day.

Anthrax is a fatal infectious disease of human and livestock and is caused by Bacillus anthracis. To establish a simple and specific assay for the clinical diagnosis of B. Anthracis infection, two oligonucleotide primers specific for the cap region of plasmid pXO2 and two specific for the pag region of plasmid pXO1 were designed and synthesised for polymerase chain reaction (PCR). The fluorescence dye SYBR Green I incorporated into the double strands was used to quantitate, and the specificity of PCR product was confirmed by the melting curve. The results showed that 0.8?mol/L primers and 3.0mmol/L Mg 2+ were optimal for this quantitative PCR assay. The sensitivity of this assay was 10 3 copies per millitier B. anthracis could be specifically distinguished from other B. cereus group of bacteria. with this assay. SYBR Green I real-time PCR appeared to be a rapid, accurate and specific methad for quantitative analysis of B. anthracis.

Objective To study the diagnostic value of multiplex protein microarray and ELISA for human serum pathogens.Methods Totally 230 national standard samples were tested by multiplex protein microarray and ELISA respectively for the pathogens of HBV,HIV,HCV and treponema pallidum(TP).Results The matched pair test for numeration data showed ?2=0.5,P=0.125,indicating that no statistical significance between the two methods.Conclusion Multiplex protein microarray shows high specificity and sensitivity to the four pathogens so that it is worth extensive application.

OBJECTIVE:To observe the efficacy of telmisartan combined with metoprolol in the treatment of chronic heart failure.METHODS:102 patients with chronic heart failure admitted in hospital from Jan.2008 to Feb.2010 were given therapy of cardiotonic,diuresis,vasodilator,anti-infection,blood sugar control.Then patients were additionally treated with telmisartan and metoprolol.The parameters before treatment and after 2 weeks of treatment were determined such as heart function,24 h dynamic electrocardiogram,Bultrasound of heart,blood pressure,heart rate,6 min walking distance,liver and kidney function,electrolytes,blood sugar,urine routine,myocardial enzyme.RESULTS:After treatment,cardiac function,heart rate and 6 min walking distance,left ventricular ejection fraction(LVEF),the number of premature beats were significantly reduced(P

The authors retrospectively analysed 67(63 in cervical cord)cases of traumatic SCIWOAR with positive MR abnormalities. It was deduced that the cases of SCIWOAR might be related with (1)those traumatic forces resulting in SCI being not so heavy and severe, (2)the cases orignally with cervical spondylopathy,(3)the limitation of the conventional X-ray examination for SCI,and (4)the cases of children relativly rare in our country and hospital.The ALL hematomas are the pathognomonic signs in the case of the acute cervical SCI within one week.The analysis demonstrated that MR investigation of the traumatic spine could give the clinical activities the correct diagnosis of different degree of SCI and dependable reference.

Objective To discuss the application of Mini Mental State Scale (the mini-mental state examination MMSE) test in assess the effect of dezocine analgesia therapy on the cognitive function of patients with agitation in recovery period of general anesthesia after gynecological laparoscopic surgery.Methods We observed 210 cases of elective gynecologic laparoscopic surgery in our hospital from January 2015 to December 2015,ASA grade Ⅰ or Ⅱ.All patients were transrered to PACU (ICU) after extubation,and were divided into three groups:A,B,C group,each with 70 cases in each group.Patients with severe agitation in A group were timely given 10mg of dezocine,patients with mild agitation in B group were given 10mg of dezocine after a delay of 5 ～ 10 minutes,and patients without agitation in C group were not given dezocine.Then the MMSE test was performed to evaluate the cognition scores of patients in the three groups.The MMSE scores immediately,15 minutes,30 minutes,60 minutes after given dezocine and 24 hours after operation were recorded.Results The statistical results showed that there were significant differences in the MMSE scores of patients immediately and at 30 minutes after given dezocine between three groups (P＜0.05);and there was no significant difference in the MMSE scores of patients at 60 minutes after given dezocine and 24 hours after operation between three groups (P ＞0.05).Conclusion Dezocine analgesia therapy has no effect on the cognitive function of patients with agitation in recovery period of general anesthesia after gynecological laparoscopic surgery.Dezocine can be safely used for analgesia and sedation treatment for patients with agitation in recovery period of general anesthesia after gynecological laparoscopic surgery analgesia,sedation agitation.

AIM: To compare the evaluations for the structure and function of the hypertrophic hearts induced by volume overload or pressure overload in rats. METHODS: Volume overload-induced cardiac hypertrophy was established by abdominal aortacaval fistula (ACF) and pressure overload-induced cardiac hypertrophy was developed by constriction of aorta (CA). The cardiac structure and function were analyzed by echocardiography, hemodynamic determination, heart weight measurement and histological examination. RESULTS: Heart weight of rats in all the operated groups was increased compared to the sham-operated groups. In 1-week ACF group, the internal diameter (0.67?0.03)cm vs (0.60?0.02)cm, P

Objective To investigate the effect of Clopidogrel on the plasma endothelin(ET)and calcitonin gene related peptide(CGRP)in patients with unstable angina pectoris(UAP).Methods Patients with UAP were divided into two groups,the regular treated group(n =50)was treated with Isoket and the Dansben group(n =50)was treated with combined Isoket and Clopidogrel.The plasma ET and CGRP were measured before and after treatment by radioimmunoreactive assay.Data were compared between the two groups and also compared with those measured in 20healthy subjects for control.Results ET level was significantly higher and CGRP level was lower in UAP patients than that in healthy subjects(P ＜ 0.05).After Clopidogrel treatment,ET was significantly decreased(P ＜ 0.01)and CGRP increased(P ＜0.05)in combined treatment group compared with patients received lsoket only.Conclusion Clopidogrel was an effective drug for UAP treatment,which could efficiently regulate the ET and CGRP metabolism.
