OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

To obtain the genome sequence of human bocavirus 2 (HBoV2), different regions of HBoV2 genome were amplified through PCR in fecal specimens which had been identified as single-positive for HBoV2 in 2010. A genome sequence of HBoV2 (HBoV2-NC, 5444 bp) was obtained after sequence assembly. The phylogenetic analysis showed that HBoV2-NC had the closest evolutionary relationship with HBoV2 Lanzhou strain. The predication of inverted terminal repeats of HBoV2-NC by DINAMelt showed that inverted terminal repeats were contained in HBoV2-NC 5' terminal, which had the typical stem-loop structure in other parvoviruses. Finally, some flanking sequences of HBoV2-NC were amplified by linker-PCR.

The picornavirus family comprises many small viruses, several of which are important pathogens of humans and livestock. The 3C protease (3Cpro) of different species and genera of picornavirus contains the classic G-X-C-G motif and Cys-His-Asp/Glu catalytic triad. 3Cpro conducts maturation cleavage in the regions of VP2-VP3 and VP3-VP1 in P1, 2A-2B and 2B-2C in P2 and the whole P3. Picornavirus 3Cpro has been shown to have significant substrate preference in Q-G/S/A/V/H/R and E-S/G/R/M as well as species and genera specificity through analyses of the maturation cleavage of picornavirus polyproteins. Innate immune adaptors such as TRIF, MAVS, IRF3, IRF7 and NEMO have various potential cleavage sites in picornavirus 3Cpro (TRIF and NEMO show considerable diversity in their cleavage sites). Useful information will be provided for the development of broad-spectrum antiviral agents as well as evasion mechanisms of the innate immune system against picornavirus 3Cpro through continued research of picornavirus 3Cpro.

Human bocavirus 1 (HBoV1) is a novel virus that mainly causes respiratory tract infection, and it has the characteristic of genome of Parvovirus, containing three open reading frames that encode non-structural proteins NS1 and NP1 and structural proteins VP1 and VP2. Circular episome is present during the rolling circle replication of HBoV1, which provides the possibility of full genome amplification and infectious clone construction to save HBoV1. The recombination between HBoV1 and HBoV2-4 occurs frequently. With the three-dimensional culture, in vitro culture of HBoV1 provides a powerful tool for research on the pathogenesis of HBoV1. This review focuses on the molecular characteristics, association with diseases, in vitro culture, diagnosis and treatment of HBoV1.

pH, affects of different alkaline materials KOH, K 2CO 3, NaOH, Na 2CO 3 on the growth, and NaCl, KCl tolerance of 29 isolates from the saline and alkaline soils in Xinjiang and Qinghai Provinces of China and 1 type strain were studied. Results showed that only a few alkaliphilic actinomycetes were Na +-obligately dependent, and K +-sensitive. Some alkaliphilic actinomycetes were CO 3 2- -sensitive, and NaCl, KCl could inhibit their growth. 4 kinds of alkaline materials had no affect on growth of alkaliphilic Nocardiopsis, and these strains showed high tolerance to NaCl, KCl. So it was presumed that only K + and CO 3 2- obligately dependent alkaliphilic Actinomycetes maybe exist in alkaline environments.

To further explore the result of bilingual teaching in pediatrics,we randomly chose 200 undergraduates of 4 class and released students'questionnaires about bilingual teaching with teaching content before and after class to assess students'understanding of bilingual teaching and analysed appraisal result.We found no significant difference of student score between students accepting bilingual teaching and not accepting the bilingual teaching,but there was difference for English tests and expression level.So we think that students can fully accept the bilingual teaching of pediatrics under the premise with selecting appropriate teaching methods and means.

Objective To explore the potential mechanism of adrenal androgen excess in patients with polycystic ovary syndrome (PCOS), ACTH stimulation test was conducted and the polymorphisms in the promoter region of CYP21 A2 gene were screened to verify the variations related to the responsiveness to ACTH stimulation. Methods 30 healthy women and 101 PCOS patients, matched for age, were recruited from Ruijin hospital. Blood biochemical examinations were taken and sex hormone profiles obtained at baseline. 17 hydroxyprogesterone( 17OHP)was measured at 0 and 60 min in an ACTH stimulation test. The -710 bp -1 bp of the promoter region of CYP21A2 was sequenced in 87 PCOS patients and 30 control subjects. Results According to the post-stimulation 17 OHP levels obtained from 30 healthy women,PCOS patients were allocated into one group with high responsiveness to ACTH ( HR-PCOS, n = 21) and the other with normal responsiveness to ACTH ( NR-PCOS, n = 80). Compared with NR-PCOS subjects, HR-PCOS patients had higher testosterone( P<0.05), basal and post-stimulation 17OHP (both P<0.01)and dehydroepiandrosterone sulfate levels (P<0.05 or P<0.01) .whereas serum cortisol and androstenedione levels were not significantly different before and after ACTH stimulation test. The genotypes of locus -535 were well correlated with post-stimulation 17OHP levels (r = 0. 20,P = 0. 03) in PCOS patients and the control subjects. The genotype T/T or allele T was significantly more frequent in subjects with a higher fertile of post-stimulation 17OHP (P<0.05 or P<0. 01). The odds ratio(OR)for higher responsiveness to ACTH in women with allele T at -535 was 3. 69 (95% CI 1. 69-8. 06,P = 0. 000 7). Conclusions The PCOS patients with higher responsiveness to ACTH are characterized by severe hyperandrogenemia and adrenal androgenexcess,suggesting that adrenal androgen excess in some PCOS patients may be due to higher responsiveness to ACTH. The polymorphism of -535C>T in the promoter region of CYP21 A2 may play a role in regulating 21 hydroxylase gene expression and further influencing 17OHP responsiveness to ACTH.

Objective To master the implementing progress of preventive measures for control of endemic arsenicosis,to observe the dynamic changes and provide the basis for prevention of national drinking-water-born endemic arsenicosis.Methods The surveillance was strictly carried out according to “The Monitoring Project for the National Drinking-Water-Born Endemic Arsenicosis(trial implementation)” in 2010.According to the results of previous investigation,11 provinces and Xinjiang Production and Construction Corps were selected as the surveillance provinces; eighty six endemic arsenicosis villages which had exposed population over 100 persons were chosen as surveillance villages in each province; forty eight potential endemic arsenicosis villages were recognized as the monitoring villages which had over 100 exposed people too.We investigated the surveillance counties and villages about the running state of water-improving projects,the arsenic content in water from resident house in potential endemic arsenicosis villages and the survey on endemic arsenicosis status based on the residents who lived in the surveillance villages.Results ①Total of 219 water-improving projects in 32 counties were monitored and 1673 villages were covered,benefiting 69.07 million population.②Total of 134 villages with high level of water arsenic were investigated.Water quality improved villages was 86,accounting for 64.18％.Normal working projects accounted for 91.86％ (79/86),intermittentl y working accounted for 4.65％ (4/86) and abandoned projects accounted for 3.49％(3/86).Passing rate of water arsenic of the projects was 91.86％(79/86).Total of 48 villages without water-improving project were investigated,and families with excessive level of water arsenic was 35.04％ (356/1016).③Total of 20 885 persons were examined in villages with improved water,incidence of endemic arsenicosis was 4.44％ (928/20 885).Among them,patients with mild arsenicosis was 3.27％ (682/20 885),with moderate was 0.80％(167/20 885) and serious patients was 0.37％(78/20 885),and detection of skin cancer 1 person.Totally 6166 persons were checked in the villages without water-improvement,incidence of endemic arsenicosis was 3.08％ (189/6166).Among them,mild patients was 2.69％ (166/6166),moderate was 0.28％ (17/6166) and the serious was 0.10％ (6/6166); 20 new cases were diagnosed,and they came from Shanxi province.Conclusions The morbidity in water-improved villages remains higher than the water-unimproved.We should establish and perfect the long-term mechanism of surveillance as soon as possible,and strengthen the management and maintenance of water-improving projects.
