Objective To examined whether prehypertension prior to pregnancy increased the risk of hypertensive disorders of pregnancy (HDP) and postpartum metabolic syndrome. Methods 1060 singleton pregnancy women with physical examination data before pregnancy were enrolled through the Kailuan study. Women with pre-pregnancy hypertension, metabolic syndrome, or no postpartum follow-up data were excluded. Pre-pregnancy prehypertension was defined as elevated blood pressure (130–139/85–89 mmHg) at the last physical examination before pregnancy. Multivariable Logistic and Cox Regression were used to examine the association between pre-pregnancy prehypertension and outcomes. Kaplan–Meier survival curve was used to analyze the cumulative incidence of postpartum metabolic syndrome. Results Among the 801 women enrolled at baseline, 173 (21.6%) had prehypertension. Overall, 61 women (7.6%) developed HDP. Kaplan–Meier survival curve showed that the incidence of postpartum metabolic syndrome was significantly higher in prehypertensive women. After adjusting for confounders, women with pre-pregnancy prehypertension were 2.09 (95% CI 1.19–3.70) and 1.91 (95% CI 1.23–2.97) times as likely to develop HDP and postpartum metabolic syndrome, compared to normotensive women. Conclusion Women with pre-pregnancy prehypertension may benefit from the more intensive monitor for HDP and postpartum metabolic syndrome.

Abstract Background Stroke is the prime cause of morbidity and mortality in the general population, and hypertension will increase the recurrence and mortality of stroke. We report a protocol of a pragmatic randomized controlled trial (RCT) using blood pressure (BP)-lowering acupuncture add-on treatment to treat patients with hypertension and stroke. Methods This is a large-scale, multicenter, subject-, assessor- and analyst-blinded, pragmatic RCT. A total of 480 patients with hypertension and ischemic stroke will be randomly assigned to two groups: an experimental group and a control group. The experimental group will receive “HuoXueSanFeng” acupuncture combined with one antihypertensive medication in addition to routine ischemic stroke treatment. The control group will only receive one antihypertensive medication and basic treatments for ischemic stroke. HuoXueSanFeng acupuncture will be given for six sessions weekly for the first 6 weeks and three times weekly for the next 6 weeks. A 9-month follow-up will, thereafter, be conducted. Antihypertensive medication will be adjusted based on BP levels. The primary outcome will be the recurrence of stroke. The secondary outcomes including 24-h ambulatory BP, the TCM syndrome score, the Short Form 36-item Health Survey (SF-36), the National Institute of Health Stroke Scale (NIHSS), as well as the Barthel Index (BI) scale will be assessed at baseline, 6 weeks and 12 weeks post initiating treatments; cardiac ultrasound, carotid artery ultrasound, transcranial Doppler, and lower extremity ultrasound will be evaluated at baseline and 12 weeks after treatment. The safety of acupuncture will also be assessed. Discussion We aim to determine the clinical effects of controlling BP for secondary prevention of stroke with acupuncture add-on treatment. Trial registration ClinicalTrials.gov, ID: NCT02967484 . Registered on 13 February 2017; last updated on 27 June 2017.

BACKGROUND: Cytokines play important roles in antiviral action. We examined whether polymorphisms of interleukin (IL)-12 receptor B1 (IL-12RB1) affect the susceptibility to and outcome of severe acute respiratory syndrome (SARS). METHODS: A case-control study was carried out in Chinese SARS patients and healthy controls. The genotypes of 4SNPs on IL-12 RB1 gene, +705A/G,+1158T/C, +1196G/C and +1664 C/T, were determined by PCR-RFLP. Haplotypes were estimated from the genotype data using the expectation-maximisation algorithm. RESULTS: Comparison between patients and close contacts showed that individuals with the +1664 C/T (CT and TT) genotype had a 2.09-fold (95% confidence interval [CI], 1.90-7.16) and 2.34-fold (95% CI, 1.79-13.37) increased risk of developing SARS, respectively. For any of the other three polymorphisms, however, no significant difference can be detected in allele or genotype frequencies between patients and controls. Additionally, estimation of the frequencies of multiple-locus haplotypes revealed potential risk haplotypes (GCCT) for SARS infection. CONCLUSIONS: Our data indicate that genetic variants of IL12RB1confer genetic susceptibility to SARS infection, but not necessary associated with the progression of the disease in Chinese population.

Summary Objective To quantify the transmissibility of severe acute respiratory syndrome (SARS) in hospitals in mainland China and to assess the effectiveness of control measures. Methods We report key epidemiological details of three major hospital outbreaks of SARS in mainland China, and estimate the evolution of the effective reproduction number in each of the three hospitals during the course of the outbreaks. Results The three successive hospital outbreaks infected 41, 99 and 91 people of whom 37%, 60% and 70% were hospital staff. These cases resulted in 33 deaths, five of which occurred in hospital staff. In a multivariate logistic regression, age and whether or not the case was a healthcare worker (HCW) were found to be significant predictors of mortality. The estimated effective reproduction numbers (95% CI) for the three epidemics peaked at 8 (5, 11), 9 (4, 14) and 12 (7, 17). In all three hospitals the epidemics were rapidly controlled, bringing the reproduction number below one within 25, 10 and 5 days respectively. Conclusions This work shows that in three major hospital epidemics in Beijing and Tianjin substantially higher rates of transmission were initially observed than those seen in the community. In all three cases the hospital epidemics were rapidly brought under control, with the time to successful control becoming shorter in each successive outbreak.

A literature review and pooled data analysis were carried out to examine the prevalence of antibodies against five influenza virus subtypes in pigs in China over a 10-year period (1999-2009). The average seropositive frequencies of subtypes H1, H3, H5, H7 and H9 were 3478/11,168 (31.1%), 2900/10,139 (28.6%), 77/5945 (1.3%), 0/1440 (0%) and 86/3619 (2.4%), respectively. There was a geographical variation in the seroprevalence of subtype H1, with the highest seroprevalence in pigs in South and East China. BLAST analysis of genetic sequences revealed that genome segments with moderate homology to the 2009 pandemic influenza A (H1N1) virus were present among swine influenza viruses isolated in China, especially in South and East China. It was concluded from both serological and genetic studies that sub-types H1. H3, H5 and H9 are currently co-circulating in pigs in China, with the H1 subtype most commonly detected, followed by H3.

Background. We followed a cohort of 773 individuals who received a monovalent vaccine against 2009 pandemic influenza A (H1N1). Approximately 6 weeks after vaccination, 12 persons developed the disease. Methods. Three groups of subjects were studied (12 patients who had or had not received previousmonovalent vaccine and 1 group of 49 control subjects who had previously been immunized with the same vaccine ). For all patients, clinical features were characterized and the causative viruses sequenced for possible mutations. Nasopharyngeal swabs, serum specimens, and peripheral blood monocyte cells (PBMCs) were collected at different time points up to 11 weeks after symptom onset to measure the virus load and humoral and cellular immune responses. Serum samples and PBMCs were also collected from 49 and 16 vaccinated control subjects, respectively. Results. Both patient groups had similar clinical manifestations. No substantial viral mutations were detected. Compared with unvaccinated patients, viral loads in vaccinated patients were initially higher, but the levels decreased faster to undetectable levels. However, the virus became detectable again for 6 of them. Two weeks after infection, vaccinated and unvaccinated patients had similar neutralizing antibody levels as the vaccinated control subjects. Thereafter, the neutralizing antibody levels decreased markedly in vaccinated patients. During the acute phase, memory T cell counts and tumor necrosis factor-a levels were significantly higher in vaccinated than in unvaccinated patients. Conclusions. Although the clinical consequences of infection are comparable between vaccinated and unvaccinated patients, humoral and cellular immune responses in vaccinated patients are boosted for some weeks, indicating an additional benefit of vaccination against 2009 pandemic influenza A (H1N1) virus.

SARS disease , *DISEASE risk factors , *REGRESSION analysis - Abstract
Objectives To describe clinical characteristics of severe acute respiratory syndrome (SARS) patients in a hospital in Tianjin, China, thereby comparing probable and suspected cases; to study risk factors associated with the death of cases; to describe the implementation of preventive interventions during the hospital outbreak. Methods Physical and haematological information was obtained from clinical records. White blood cell counts, and percentages of neutrophilic granulocytes and neutrophilic lymphocytes were measured. The service department of the hospital provided information about daily use of protective materials. Differences in clinical symptoms between probable and suspected SARS cases were tested by Fisher’s exact test. Non-linear mixed modelling was used to test for differences between the haematological patterns for probable and suspected cases. Risk factors for dying among probable SARS cases were tested by logistic regression. Results The SARS outbreak started with a patient from Beijing on 15 April 2003, and spread quickly among the healthcare workers and in-patients in the hospital. In total 90 probable and 21 suspected cases were reported, with 17 deaths among them (case fatality rate 15%). Haematological patterns were significantly different between probable and suspected cases, whereas the percentages with certain clinical symptoms showed no apparent difference. Death of probable SARS cases was only significantly associated with high age and use of a respiratory machine (mainly for the most severe cases), whereas e.g. co-morbidity and steroid treatment showed no impact in multivariate analysis. Stringent control measures, including distribution of huge numbers of protective materials, started on 20 April, which soon lead to a strong decrease in the incidence of new cases. After the last SARS case left the hospital on 6 June, protective materials were dispensed at substantially lower rates, but not to zero, as was the case during the first days of the outbreak. Conclusion The working definition of probable SARS used during the epidemic appeared to have been fairly accurate. Many valuable lessons were learned regarding prevention of hospital spread of infection, especially the need to have sufficient protective supplies available and to implement these rigidly and at an early stage of an (threatening) epidemic.
