The 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) catalyzes the conversion of HMG-CoA to mevalonate in mavalonic acid pathway, which is the first committed step for isoprenoid biosynthesis in plants. However, it still remains unclear whether HGMR gene plays a role in the isoprenoid biosynthesis in Dendrobium officinale, an endangered epiphytic orchid species. In the present study, a HMGR encoding gene, designed as DoHMGR1 (GenBank accession JX272632), was identified from D. officinale using the reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods, for the first time. The full length cDNA of DoHMGR1 was 2 071 bp in length and encoded a 562-aa protein with a molecular weight of 59.73 kD and an isoelectric point (pI) of 6.18. The deduced DoHMGR1 protein, like other HMGR proteins, constituted four conserved domains (63-561, 147-551, 268-383 and 124-541) and two transmembrane motifs (42-64 and 85-107). Multiple sequence alignment and phylogenetic analyses demonstrated that DoHMGR1 had high identity (67%-89%) to a number of HMGR genes from various plants and was closely related to Vanda hybrid cultivar, rice and maize monocots. Real time quantitative PCR (qPCR) analysis revealed that DoHMGR1 was expressed in the three included organs. The transcripts were the most abundant in the roots with 2.13 fold over that in the leaves, followed by that in the stems with 1.98 fold. Molecular characterization of DoHMGR1 will be useful for further functional elucidation of the gene involving in isoprenoid biosynthesis pathway in D. officinale.

Objective : To investigate the willingness to receive HIV testing in primary health service institutions (PHSIs) among young students in Wuhan City, so as to provide the evidence for improving the detection of HIV testing among young students. Methods: Fifteen PHSIs were sampled using a stratified random sampling method in 14 districts of Wuhan City, and school students at ages of 15 to 24 years were sampled from each district using a convenience sampling method. Participants' demographics, awareness of AIDS-related knowledge, HIV testing and willingness to receive HIV testing were collected using questionnaires, and factors affecting the willingness to receive HIV testing in PHSIs were identified among school students using a multivariable logistic regression model. Results : A total of 301 questionnaires were allocated, and 299 valid questionnaires were recovered, with an effective recovery rate of 99.34%. The respondents included 143 men (47.83%) and 156 women (52.17%), and had a mean age of (19.36±2.40) years; there were 223 respondents with an educational level of diploma and above (74.58%). The awareness of AIDS-related knowledge was 71.57% among the respondents, and 144 respondents had received AIDS-related health education in PHSIs (48.16%). There were 34 respondents that had received HIV testing (11.37%) and 203 respondents that were willing to receive HIV testing in PHSIs (67.89%). The respondents that were unwilling to receive HIV testing in PHSIs were mainly attributed to considering to be unlikely to get HIV infections (82.29%). Multivariable logistic regression analysis showed that school students who knew AIDS-related knowledge (OR=2.797, 95%CI: 1.583-4.941), knew free HIV counseling and testing services in PHSIs (OR=2.070, 95%CI: 1.123-3.814), and had received AIDS-related health education in PHSIs (OR=2.814, 95%CI: 1.573-5.032) were more willing to receive HIV testing in PHSIs. Conclusions There were 67.89% of school students that were willing to receive HIV testing in PHSIs in Wuhan City, and the willingness to receive HIV testing was correlated with the awareness of risk of HIV infections, and awareness and experience of AIDS control services in PHSIs.

Based on the complete genome sequence of Newcastle disease virus (NDV) ZJI strain,seven pairs of primers were designed to amplify a cDNA fragment for constructing the plasmid pNDV/ZJI,which contained the full-length cDNA of the NDV ZJI strain.The pNDV/ZJI,with three helper plasmids,pCIneoNP,pCIneoP and pCIneoL,were then cotransfected into BSR-T7/5 cells expressing T7 RNA polymerase.After inoculation of the transfected cell culture supernatant into embryonated chicken eggs from specific-pathogen-free (SPF) flock,an infectious NDV ZJI strain was successfully rescued.Green fluorescent protein (GFP) gene was amplified and inserted into the NDV full-length cDNA to generate a GFP-tagged recombinant plasmid pNDV/ZJIGFP.After cotransfection of the resultant plasmid and the three support plasmids into BSR-T7/5 cells,the recombinant NDV,NDV/ZJIGFP,was rescued.Specific green fluorescence was observed in BSR-T7/5 and chicken embryo fibroblast (CEF) cells 48h post-infection,indicating that the GFP gene was expressed at a relatively high level.NDV/ZJIGFP was inoculated into 10-day-old SPF chickens by oculonasal route.Four days post-infection,strong green fluorescence could be detected in the kidneys and tracheae,indicating that the recombinant GFP-tagged NDV could be a very useful tool for analysis of NDV dissemination and pathogenesis.

BACKGROUND: The quality of chest compressions can be significantly improved after training of rescuers according to the latest national guidelines of China. However, rescuers may be unable to maintain adequate compression or ventilation throughout a response of average emergency medical services because of increased rescuer fatigue. In the present study, we evaluated the performance of cardiopulmonary resuscitation (CPR) in training of military medical university students during a prolonged basic life support (BLS). METHODS: A 3-hour BLS training was given to 120 military medical university students. Six months after the training, 115 students performed single rescuer BLS on a manikin for 8 minutes. The qualities of chest compressions as well as ventilations were assessed. RESULTS: The average compression depth and rate were 53.7±5.3 mm and 135.1±15.7 compressions per minute respectively. The proportion of chest compressions with appropriate depth was 71.7％±28.4％. The average ventilation volume was 847.2±260.4 mL and the proportion of students with adequate ventilation was 63.5％. Compared with male students, significantly lower compression depth (46.7±4.8 vs. 54.6±4.8 mm,P<0.001) and adequate compression rate (35.5％±26.5％ vs. 76.1％±25.1％,P<0.001) were observed in female students. CONCLUSIONS: CPR was found to be related to gender, body weight, and body mass index of students in this study. The quality of chest compressions was well maintained in male students during 8 minutes of conventional CPR but declined rapidly in female students after 2 minutes according to the latest national guidelines. Physical fitness and rescuer fatigue did not affect the quality of ventilation.

OBJECTIVETo observe the therapeutic effect of He's Santong needling method on neurological functional deficit in the patient of ischemic apoplexy, and search for an effective method for treatment of ischemic apoplexy.

METHODSAccording to the randomized and multi-central trial principle, 319 cases enrolled were randomly assigned to an observation group of 161 cases and a control group of 158 cases. The observation group were treated with He's Santong needling method, i. e. blood letting, puncturing with a red-hot needle and filiform needle therapy by stages, and the control group were treated with acupuncture at 12 points of the hand and foot routinely selected in the department, once daily. After treatment of 30 days, changes of neurological functional deficit score were investigated in the two groups.

RESULTSThe total effective rate was 91.93% in the observation group and 70. 25% in the control group with a significant difference between the two groups (P<0.05); there was no significant difference in changes of the neurological functional deficit score between the patients at the acute stage and the convalescence (P > 0.05).

CONCLUSIONThe therapeutic effect of He's Santong needling method on ischemic apoplexy at acute stage or convalescence is better than that of the routine point selection.
