With the development of functional genomics, high throughput analysis of genes’ function has been the mainstream of research, and exogenous gene's over expression via Agrobacterium-mediated transformation is the most commonly used method in gene functional analysis.The versatile plant expression vector cassette named pBHT-5 was constructed by the method of site-specific mutagenesis based on pBI121. First of all, the restriction enzyme SfiI recognition site in trfA gene (X00713) which was relevant to plasmid replication and stability was replaced without changing its amino acid composition. And then the SfiIA,SfiIB sites were added between promoter CaMV35s and terminator NOS. The versatile plant expression vector cassette can be directly used to construct plant expression vector containing the full-length genes cloned by Clontech SMARTTM technology, which will raise the efficiency of vector construction. The result will provide basis of new genes’ high throughput screening and functional analysis, then get the new genes functioning in plant osmotic stress resistance.

Objective To determine the prevalence of female urinary incontinence among Chinese people in different areas. Methods A sampling survey of urinary incontinence was conducted on 668 female adults in a Beijing community,the Uygur region and a residential district inside the First Hospital of Peking University with questionnaire. Results The prevalence of female urinary incontinence was 46.5%(94/202) in the Beijing community,43.8%(134/306) in the Uygur Region and 40.6%(58/143) in the residential district inside the First Hospital of Peking University.The ratios of those who consulted with doctors to the separate surveyed population were 24.5%(23/94),29.1%(39/134),13.8%(8/58),respectively. Conclusions The prevalence of female urinary incontinence is similar in different population.Only a few of these women went to doctors,especially among the hospital staff and workers.

With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Allergic rhinitis (AR), with an increasing uptrend of the prevalence in many developed and developing countries, is a global health problem that affects people of all ages and ethnic groups. However, data on the prevalence of self-reported AR in western China are rare. This study investigated the epidemiological features of self-reported AR in western China. In the cross-sectional, population-based study, a validated questionnaire survey on self-reported AR was carried out in 4 major cities in western China by multistage, stratified and cluster sampling, from January to December 2008. The total prevalence rate was 34.3%, with 32.3% (Chongqing), 34.3% (Chengdu), 37.9% (Urumqi), 30.3% (Nanning), respectively. The prevalence presented to increase with age before 30 years old while decrease with age after 30 years old, and the highest prevalence was in 19-30 years group in Chongqing, Chengdu and Nanning which significantly showed "persistent and moderate-severe" type (P<0.0001); In Urumqi, there wasn't a significant increasing or decreasing trend of prevalence rate with age but with an "intermittent and mild"predominance (P<0.0001). There were no distinct sexual differences in prevalence rates in the 4 cities. The morbidity was positively related to monthly average temperature and sunshine (r=0.76645, P=0.0036; r=0.67303, P=0.0165), but negatively associated with relative humidity (r=-0.64391, P=0.0238) in Urumqi. Interestingly, the monthly morbidity was negatively associate with average temperature, sunshine and precipitation in Nanning (r=-0.81997, P=0.0011; r=-0.60787, P=0.0360; r=-0.59443, P=0.0415). Self-reported AR is becoming common in western China with a rapid development in recent years, affecting about three persons out of ten. The climatic factors may have an indirect impact on the prevalence rate through the effects on the local allergens.
