Objective To develop prototype foamy virus (PFV) detection method by loop-mediated isothermal amplification. Methods Three pairs of primers targeting core region of PFV integrase were designed in this study and Bst DNA polymerase was used to amplify target sequence at 63℃. The system was established with all the conditions optimized. Results The method was established with the plasmid containing target sequence as the template. This method could specifically detect PFV infectious clone, no crossreaction was observed with human immunodeficieney virus infectious clone, bovine immunodefieiency virus infectious clone and bovine foamy virus infectious clone as templates. The detection capability of this system was 50 copy, one order more sensitive than PCR. The amplification could be finished in 15 min and human genomic DNA did not adversely affect the amplification efficiency. Conclusion The PFV detection method by loop-mediated isothermal amplification was established and it had potential usefulness in PFV detection.

Objective To evaluate the diagnosis value of echocardiography in infants with complete transposition of the great artery.Methods Echocardiographic characteristics of 13 cases with completely artery transposition were compared with the results of operation.Results Simple artery transposition in complete ventricular septum occurred in 5 cases(atrial septal defect with patent arterial duct in 2 cases,simple patent arterial duct in 2 cases, simple atrial septal defect in 1 case).Great artery transposition with ventricular septal defects occurred in 8 cases (great artery transposition with ventricular septal defects, atrial septal defects,patent arterial duct in 3 cases; atrial and ventricular septal defect in 1 case; ventricular septal defect in 3 cases; ventricular septal defect with two branches of right coronary artery in 1 case).Out of 13 cases,the ultrasound diagnosis in 12 cases before operation was completely consistent with that of operation.Coronary deformity in one case had not been detected by echocardiography.Conclusions Great artery transposition in infants can be diagnosed and typed early by echocardiography,which provides the reliable information for clinic selection of operation and follow up survey.

Objective Human Papillomavirus (HPV) is necessary to the development of cervical cancer.Until now,the distribution of specific HPV type has not been identified clearly yet.Besides,the relationship between age and the HPV type-specific distribution in cervical adenocarcinoma needs to be further investigated.Methods This study included 32 specimens of cervical adenocarcinoma out of a multicenter clinical study in China.The specimen blocks were sliced by sandwich method.DNA was amplified by SPF10-PCR method.DNA genotyping used LiPA method.All biopsy specimens had pathologic diagnosis.The prevalence of HPV type-specific distribution was described and the differences were analyzed statistically.Results 32 adenocarcinoma cases were included in this sttudy.HPV positive rate was 53.1％ (17/32).HPV-18 was the most prevalent type,which took up 47.4 ％ (8/17) of the total HPV positive cases,followed by HPV-16,which took up 26.3 ％ (5/17) of the total HPV positive cases.Other HPV types detected were HPV-39,HPV-45 and HPV-66.One multi-infection case was found (HPV-18 and HPV-66 co-infection).The average ages of HPV-16 and HPV-18 were 48.6 and 40.6 years old respectively,which showed statistically difference (P =0.049).When the patients younger than 50 years old were compared with the patients equal or older than 50 years old as two age groups,HPV positive rate did not show significantly statistical difference (P =0.074) between the two age groups.The prevalence of HPV-18 manifested significant differences between the two age groups in both HPV positive adenocarcinoma cases and overall adenocarcinoma cases (P =0.029and P =0.003 respectively).The prevalence of HPV-16 did not show any significant statistical difference between the two age groups in either HPV positive adenocarcinoma cases or overall adenocarcinoma cases (P =0.6 and P =1 respectively).HPV-16 and/or HPV-18 infection (at least one positive) in HPV positive adenocarcinoma cases did not have statistical significance (P =0.052),while in overall adenocarcinoma cases,HPV-16 and/or HPV-18 infection presented significant statistical difference (P =0.005).Conclusion HPV-18 and HPV-16 were two most prevalent HPV types in cervical adenocarcinoma.HPV infection and HPV-18infection were more common in young women.The prevalence of HPV-16 was more common in older adenocarcinoma cases compared with HPV-18.Those findings will provide evidence for the evaluation of HPV vaccine in preventing cervix related diseases.

Objective To investigate the characteristics of common causes of acute pancreatitis (AP) in China and to evaluate the association of the aetiology with the severity of disease.Methods The relevant literature was searched from the China National Knowledge Infrastructure (CNKI) database (1989.1-2015.3),WANFANG database (1999.1-2015.3),VIP database (1994.1-2015.3),and China Academic Journal Network Publishing Database (CAJD).To collect related literature about aetiology and the severity of acute pancreatitis,Meta analysis was performed for gallstone,alcohol,hyperlipidemia and other AP from the aspects of the severity of disease in the literature which reaches the criteria.Results The Meta analysis included 24 clinical articles which were accordance with the criteria,totally 17359 patients,including 8673 cases of biliary AP [6690 cases of mild acute pancreatitis (MAP),1983 cases of acute necrotizing pancreatitis (ANP)],1408 cases of alcoholic AP (1022 cases of MAP,386 cases of ANP),1753 cases of hyperlipidemia AP (1107 cases of MAP,646 cases of ANP),and 5525 cases of other aetiology (4179 cases of MAP,1346 cases of ANP).The Meta analysis showed that among the common causes which was developed to AP,there was significant difference between biliary AP and alcohol AP (OR =0.65,95％ CI:0.45 ～0.93,P ＜ 0.05).There was significant difference between biliary AP and hyperlipidemia AP (OR =0.51,95％ CI:0.33 ～0.79,P ＜0.05).However,there was no significant difference between alcoholic AP with hyperlipidemia AP (OR =0.70,OR =0.70,95％ CI:0.46 ～ 1.05,P ＞ 0.05).Conclusions There is difference in the severity of AP caused by different reasons in China.There is more likely that hyperlipidemia AP and alcohol AP easily developed into ANP than biliary AP.However,further investigation and large-scale clinical trials will be needed to confirm this conclusion.

Objective To investigate the different effect among ropivacaine,bupivacaine,lidocaine on analgesia after harvesting grafts from the scalp in burn patients. Methods 84 patients who need harvesting grafts from the scalp after burn were divided in 4 groups random-ly(n=21). Patients in group C hypodermically injected with saline 200 mL were control,while patients in group R injected with 0. 05% ropi-vacaine 200 mL,group B with 0. 188% bupivacaine,and group L with 0. 1% lidocaine. Motor activity assessment scale( MAAS) and visual analogue scale(VAS) were made before anesthesia(T0) and 20 min,5 h,10 h after awake of patients. VAS were made focus on head and body in part. Vital signs were also monitored and recorded for assessment of security. Results All patients in 4 groups had passed the period of operation safely. Patients in group R have better VAS than other groups. Conclusion Low concentration ropivacaine hypodermically injec-tion of head is helpful to relieve the pain after harvesting grafts from the scalp.

OBJECTIVETo observe the therapeutic angiogenesis effect of naotai recipe (NR) on local ischemia/reperfusion (I/R) injury of rats by observing signaling pathway of hypoxia-inducible factor-lα (HIF-1α) and vascular endothelial growth factor (VEGF).

METHODSTotally 120 Sprague-Dawley (SD) rats were randomly divided into 4 groups, namely, the normal control group (n =12), the sham-operation group (n =12), the I/R model group (n =48), and the NR group (n =48). Cerebral I/R injury models were established using thread suture method. Rats in the I/R model group and the NR group were sub-divided into 4 sub-groups according to the 1st, 3rd, 5th, and 7th I/R day (n =12). The phenomenon of neovasculization was observed by immunofluorescence staining. The protein and mRNA expression levels of HIF-la, VEGF-A, and VEGFR II receptor were detected by RT-PCR.

RESULTSThere were a large amount of labels for neovasculization in the ischemic area of the NR group. Double-immunofluorescence labeling [vWF (red) and BrdU (green)] was observed in the NR group. Compared with the model group, the HIF-1α protein expression was obviously enhanced on the 1 st day of I/R (P <0.01), and the VEGF protein expression started to enhance on the 3rd day in the NR group (P <0.01). The VEGFR protein expression level was the highest in the NR group on the 5th day of I/R (P <0.01). The protein expression of VEGF and HIF-1α started to decrease on the 7th day of I/R.

CONCLUSIONNR could strengthen angiogenesis after I/R by elevating the expression of HIF-lα and activating HIF-lα/VEGF signaling pathway.
