Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Abstract: Objective To study severe fever with thrombocytopenia syndrome virus (SFTSV) in tick samples from different species and genera in Suizhou City, Hubei Province, China, and to explore the phylogenetic relationship between ticks and patients sources of viruses at the molecular evolutionary level. Methods In 2016 and 2017, over a continuous two-year period, 1 158 ticks were collected from Suizhou, Hubei, and their species and genera were identified. Meanwhile, 86 serum samples were collected to detect SFTSV RNA by real-time quantitative reverse transcription-PCR. All viral RNA-positive supernatants of tick homogenates were inoculated into Vero cells for viral isolation, and full genome sequencing of isolated strains was conducted. Phylogenetic tree research on SFTSV strains from ticks and cases was performed using the bootstrapped maximum-likelihood (1 000 iterations) method with Molecular Evolutionary Genetics Analysis (MEGA) software, ver. 11.0 to provide confidence estimates. Results Haemaphysalis longicornis, Ixodes sinensis, and Rhipicephalus microplus were the dominant species (95.34%) in Suizhou City, Hubei Province, China. Tick samples were pooled according to their species and developmental stage, yielding 832 pools, of which 4 were positive for SFTSV by qRT-PCR. The overall minimum infection rate (MIR) in the region was 0.35%. One SFTSV strain named HB 2016-P35, was successfully isolated from Haemaphysalis longicornis and demonstrated high homology to 16 previously reported patient-derived viruses in Hubei Province, especially to the human strain HB 2017-49 from the same region, with a genome similarity of 99.9%. In addition, the molecular phylogenetic analysis revealed five distinct SFTSV genotypes in Hubei, covering almost all currently known SFTSV genotypes. Conclusions Some areas of Suizhou City, Hubei Province, demonstrate a relatively low level of SFTSV carrying and transmission by ticks. The new SFTSV strain isolated from ticks exhibits similar genotype characteristics and high sequence homology with viruses carried by cases in surrounding cases. The study suggests that tick-to-human transmission is most likely the pathway for human infection with SFTSV, highlighting the need for continual and long-term monitoring of tick carriage of SFTSV in endemic areas.

ObjectiveThis study performed a scoping review to comprehensively analyze and report the information on the instructions of Chinese patent medicines and clinical research evidence for the treatment of respiratory diseases in children. MethodChinese patent medicines against respiratory diseases in children were obtained by searching the three major drug catalogues. The Chinese and English databases were searched for relevant literature,followed by data statistics and visualized analysis. ResultAfter screening and analysis,52 Chinese patent medicines were included,involving nine dosage forms. The main drugs were Scutellariae Radix,Armeniacae Semen Amarum,Forsythiae Fructus,etc. The main functions included clearing heat and releasing exterior syndrome,and relieving cough and dissipating phlegm. The indications mainly included common cold with wind-heat syndrome and cough in children. Adverse drug reactions and contraindications were only specified in 19.23% (10/52) of Chinese patent medicines,and the rest only displayed "unclear". A total of 279 articles were included,including 277 articles from Chinese Core Periodicals and two articles from SCIE. In terms of research type,those articles included 253 randomized controlled trials (RCTs,with six dosage form/dose comparisons involved),11 retrospective analyses based on Hospital Information System (HIS) data,one case series,13 systematic reviews/Meta-analyses (with two network Meta-analyses involved),and one economic evaluation article. Among them,72.76% (203/279) of the articles were published in the Core Journals of Chinese Science and Technology. Only 33 Chinese patent medicines were involved,and Xiaoer Feire Kechuan Oral Liquid was the top 1 under investigation,accounting for 15.71% (44/280). The indicated diseases were mainly infantile pneumonia,bronchitis,respiratory tract infection,cough,asthma,and other western medicine diseases. Xiaoer Chiqiao Qingre Granules and Xiaoer Dingchuan Oral Liquid were used off-label. The sample size was concentrated in 51-150 cases,accounting for 67.17% (178/265). The interventions in the experimental group were mainly Chinese patent medicine + western medicine + basic treatment or Chinese patent medicine + western medicine. The main outcomes were the effective rate and the improvement of clinical symptoms. The adverse reactions were mainly gastrointestinal reactions,drug-induced skin symptoms,etc.,and two studies have shown that drug doses were associated with adverse reactions. ConclusionIn research years,the research on Chinese patent medicines in the treatment of respiratory diseases in children has advanced rapidly. However,there are still some problems that need to be resolved in the future,such as incomplete information on drug content in the instruction,concentrated drugs to be studied,limited indications,failure to highlight the characteristics of traditional Chinese medicine (TCM) syndromes,unstandardized research design,and an incomplete reflection of Chinese patent medicine.

Health research priority setting, based on the existing disease burden or healthcare needs, screens out specific areas or topics with relatively high research priority by scientific and systematic methods, and optimizes the allocation of health resources by influencing healthcare decision-making, so as to alleviate the imbalance between regional or global health and development. Many developed countries have carried out related research and practical work on different scales, and the World Health Organization (WHO) attaches great importance to the transformation and application of relevant achievements in developing countries. As the largest developing country in the world, China's research in this field started relatively late, and only a small number of scholars have carried out part of the localization methodology research and practice according to the specific national conditions. However, health research priority setting has not yet attracted the attention of large-scale research institutions or government organizations in China. Although the priority setting is rarely mentioned in the research on traditional Chinese medicine (TCM), the research and decision-making on the diseases responding specifically to TCM can also be regarded as the practical work of exploring the priority of TCM. Policymakers have a sense of priority support in the "priority of TCM research", but the decisions from the top design are mainly based on the consensus reached by high-level think tanks. There is a lack of extensive research, and moreover, the data of multiple stakeholders are not included. Therefore, it is urgent to introduce appropriate priority setting methods to solve the problem of transparency and scientificity in the decision-making process. Given the perspective of the specific implementation, the present study introduced three international priority setting methods, i.e., the James Lind Alliance and Priority Setting Partnerships(JLAPSP,)the Child Health and Nutrition Research Initiative(CHNRI), and the Council on Health Research and Development (COHRED), and presented relevant recommendations on how to apply them in the research of TCM, which is expected to provide references for the local research.

Objective:To investigate the distribution of HIV-1 genotypes and drug resistance in newly diagnosed HIV-1 patients in Baoding in 2020.Methods:A self-developed method was used to amplify the pol gene sequence of HIV-1, and the sequencing results were analyzed by phylogenetic analysis and compared with the Stanford drug resistance database to determine the HIV-1 subtypes and gene mutations. Results:A total of 96 patients with HIV-1 infection were recruited in this study, and 83 pol gene sequences were successfully obtained. In the study population, 88 (91.7%) were male with an average age of 39 years and 54 (56.3%) were married. Most of the patients were infected through sexual contact (95.8%, 92/96), and 75.0% (72/96) were through homosexual transmission. Phylogenetic analysis showed that various HIV-1 subtypes were detected and among them, CRF01_AE (51.8%, 43/83), CRF07_BC (24.1%, 20/83) and B subtype (10.8%, 9/83) were the most epidemic strains. Moreover, the subtypes of newly identified recombinant strains in recent years accounted for 13.3% (11/83). Drug resistance test results showed that the pre-treatment drug resistance rate in newly diagnosed HIV-1 patients was 8.4% (7/83), and the drug resistance rates to protease inhibitor (PIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and integrase inhibitors (INIs) were 3.6% (3/83), 1.2% (1/83) and 3.6% (3/83), respectively. Conclusions:The HIV-1 subtypes in the newly diagnosed population in Baoding in 2020 were complex and diverse. There were many unique recombinant strains and drug-resistant strains. Therefore, it was necessary to strengthen drug resistance monitoring as well as the prevention and control of HIV-1 infection in this area.
