Objective To discuss human papilloma virus(HPV)prevalence and HPV genotypes distribution and the infection factors,to provide scientific guidance for the prevention and treatment of cervical cancer.Methods From March to November in 2009,605 women received cervical HPV testing in the Tumor Hospital of Harbin Medical University,to obtain specimens of cervical cytology,rapid flow-through hybridization technique (namely Hybribio flow-through hybridization)was used to detect HPV genotypes simultaneously.Single-factor and multivariate factors non-conditional Logistic regression analytic method was used to discuss the relationship between HPV infection of females and age,marital condition,level of education,level of income,occupation,initial age for sex,contraception,number of pregnancies,delivery approach and smoking.Results HPV infection rate was 21.49%(130/605),the positive rate of HPV infection in high-risk subtypes was 15.70%(95/605),the most common type was 5.29%(32/605)in the samples.Single factor non-conditional logistic regression model analysis showed that initial age for sex was the risk factor(X2=4.4618,P<0.05),HPV prevalence increased with a lower initial age for.sex reduced.But there was no significant difference in age,marital condition,education,income,occupation,contraception,number of pregnancy,delivery approach and smoking teams(X2=0.0525,1.8510,1.0348,0.2592,1.1176,1.5664,2.8835,1.4597,2.6161,all P>0.05).The analysis of multivariate factors nonconditional Logistic regression showed that the age of initially having sex,marital status and number of pregnancies were the risk factors(X2=21.6637,8.0574,15.7573,all P<0.05).Conclusions The risk factors for HPV infection are mainly about having sex too young,marital status and number of pregnancies,attention should be paid to screening for HPV.

This paper studied the HPLC and NIRS fingerprints of Chrysanthemum with different processing methods, including directly drying, drying after steamed, and drying after fried. The method of discriminant analysis of TQ software was used to analysis the NIRS fingerprint of Chrysanthemum with three different processing methods, and the results were consistent with HPLC fingerprint similarity analysis. NIRS and HPLC fingerprints were of different characteristics, and the combination of the two methods can quickly and accurately identify Chrysanthemum with different processing methods.

Objective:To describe the current situation in the nursing practice and their turnover intention in township health centers, and to analyze the changing potential influence in the nursing practice scope and workloads on their intention to leave those health centers. Methods:By means of a questionnaire, we conducted a survey on 167 nurses and interviewed 44 of them, all from 45 township hospitals within three provinces in China. Results:Since the healthcare system reform, the nursing workload in the township health centers significantly increased. 62% of the re-spondents considered their workload as heavy. Typically, the nursing work accounted for about 60% and the public health service work accounted for only 21% of the working hours. About 30% of the respondents were intended to leave their current job. The participating public health service was associated with intention to leave the job after con-trolling the province, workload, marital status, formal position, educational level and length of nursing service (P<0. 05). Conclusions:Since the healthcare system reform, the nursing practice scope in township health centers has been expanded and the workload increased considerably. But so far, expanding the scope of the nursing work may have potentials in reducing the intention of nurses to leave their current positions.

Objective To explore the changes of soluble tumor necrosis factor receptor type 1(sTNFR1)in children with acute virus encephalitis(VE)and its clinical significance.Methods The levels of tumor necrosis factor-?(TNF-?),sTNFR1 and neuron specific enolase(NSE)in cerebrospinal fluid were determined by enzyme-linked immunosorbent assay(ELISA)in 55 children who were admitted with VE,including 25 cases with severe VE(SVE)and 30 cases with mild VE(MVE).Fifteen cases without VE were as control group.Results The levels of TNF-?,sTNFR1 in cerebrospinal fluid in encephalitis children were significantly higher than that in control group(Pa

OBJECTIVETo observe the effect of electric acupuncture (EA) on the Nogo receptors (NgR) protein expression in the cerebral cortex, the medulla oblongata, and the spinal cord of cerebral ischemia-reperfusion (I/R) stroke-prone renovascular hypertensive rats (RHRSP) with middle cerebral artery occlusion (MCAO) at different time points, and to investigate its possible mechanisms for remote-organ injury of acute cerebral infarction (ACI).

METHODSThe RHRSP model was duplicated in male SPF grade SD rats. Then the MCAO model was prepared by a thread stringing method. Rats were divided into the hypertension group,the sham-operation group, the MCAO group, the EA group, and the sham-acupoint group by random number table method, 60 in each group. Rats in the MCAO group only received MCAO reperfusion treatment. Those in the sham-operation group only received surgical trauma. Baihui (DU20) and Dazhui (DU14) were needled in the EA group, once daily for a total of 28 days.The needles were acupunctured at the skin one cun distant from Baihui (DU20) and Dazhui (DU14) and then the same EA treatment was performed in the sham-acupoint group. At day 1, 7, 14, 28 after treatment, six rats were executed from each group, and their right cortex and medulla oblongata, and the left spinal cord were isolated. The infarct volume was detected by Nissl's staining method. The NgR expression was detect by Western blot.

RESULTS(1) In the cortex area: compared with the hypertension group,the NgR expression increased in the MCAO group at day 1,7,14,and 28 after MCAO (P < 0.05). Compared with the MCAO group, the NgR expression of the EA group and the sham-acupoint group were equivalent at 1 day af ter MCAO (P > 0.05). At day 7, 14,and 28 after MCAO, the NgR expression decreased in the EA group (P < 0.05), it was quite similar to that in the sham-acupoint group (P > 0.05). (2) In the medulla oblongata area: compared with the hypertension group, the NgR expression was equivalent in the sham-operation group. the MCAO group,the EA group, and the sham-acupoint group at 1 day after MCAO (P > 0.05). At day 7.14, and 28 after MCAO, the NgR expression increased in the MCAO group (P < 0.05). Compared with the MCAO group,the NgR expression decreased in the EA group at day 7, 14, and 28 after MCAO (P < 0.05), whereas it was similar in the sham-acupoint group (P > 0.05). (3) In the spinal cord area: compared with the hypertension group, the NgR expression was equivalent in the sham-operation group, the MCAO group,the EA group, and the sham-acupoint group at day 1 and 7 after MCAO (P > 0.05). At day 14 and 28 after MCAO, the NgR expression increased in the MCAO group (P < 0.05). Compared with the MCAO group, the NgR expression decreased in the EA group at day 14 and 28 after MCAO (P < 0.05), whereas it was equivalent in the sham-acupoint group (P > 0.05).

CONCLUSIONSIncreased NgR expression in the cerebral cortex, the medulla oblongata, and the spinal cord of cerebral infarct rats was an important reason for involving remote-organ injury of ACI. The protective effect of EA on hypertensive I/R cerebral injury rats might be closely related to down-regulating central nervous system myelin growth inhibition mediated factors Nogo-A receptor NgR protein expression.

Thienorphine is a chemically-new opioid developed in Beijing Institute of Pharmacology and Toxicology. To elucidate the chemical basis for the unique pharmacological effects of thienorphine, 15 derivatives were synthesized according to combinatorial chemistry and the structure-activity relationships of these compounds were studied. It is demonstrated that thienorphine is a potent long-acting partial agonist. N-Cyclopropylmethyl is responsible for the antagonist effect of thienorphine. More importantly, thiophene at the end of side chain is most likely the pharmacophore accounts for the long-lasting effect of thienorphine. Change of the connection of thiophene and the side chain does not result in changes in the antinociceptive activity.
