Preliminary survey report on the clinical validation of in-use electronic sphygmomanometers in China / 中华心血管病杂志

Objective: To explore the percentage of in-use electronic sphygmomanometers independently validated clinically in China. Methods: We conducted a cross-sectional survey and Beijing, Shenzhen, Shijiazhuang, Datong, and Shihezi were selected according to the geographical location and economic level. In each site, one tertiary hospital, two community health centers, and 20 families with electronic sphygmomanometers in use were chosen. The information of electronic sphygmomanometers including brand, model, manufacturer and production date were obtained by the trained staff. Ten electronic sphygmomanometers from each hospital, five electronic sphygmomanometers from each community health center, and one electronic sphygmomanometer from each family were surveyed, and the user's subjective judgment results and judgment basis on the accuracy of the electronic sphygmomanometer measurement were collected. We searched six registration websites (Medaval, Stride BP, dabl Educational Trust, British and Irish Hypertension Society, American Medical Association and Hypertension Canada) and two research databases (PubMed and CNKI) for the clinical validation status of each electronic sphygmomanometer. Results: A total of 200 electronic sphygmomanometers were investigated in this study, of which only 29.0% (58/200) passed independent clinical validation. When stratified by users, the percentage of being clinical validated was 46.0% (23/50) for electronic sphygmomanometers in hospitals, 42.0% (21/50) for those in community health centers and 14.0% (14/100) for those in home use, respectively, and the proportions between the three groups were significantly difference (P<0.001). Doctors in tertiary hospitals and community health service centers judged the accuracy of electronic sphygmomanometers mainly on the basis of "regular correction" (41.0% (41/100)) and "comparison with other electronic sphygmomanometers" (20.0% (20/100)), while among home users, 41.0% (41/100) were not clear about the accuracy of electronic sphygmomanometers, and 40.0% (40/100) made the judgment by "comparison with the devices in hospitals". Conclusion: The clinical validation of in-use electronic sphygmomanometers in China is low. Most of users, including healthcare professionals, are not aware of clinical validation of electronic sphygmomanometers.

Guideline for the diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients (version 2023) / 中华创伤杂志

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique (version 2023) / 中华创伤杂志

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

Transcriptome analysis and differential gene screening of Panax ginseng seed in different sand storage stages / 药学学报

Analyze the changes in gene expression profiles during the process of Panax ginseng seed dormancy release, and screen for differential genes, providing a basis for analyzing the mechanism of P. ginseng seed dormancy release. Comparative transcriptome analysis was conducted by using RNA-Seq sequencing technology in P. ginseng seeds stored at different low temperature. A total of 80.97 Gb of Raw reads and 80.19 Gb of Clean reads were obtained from the transcriptome. Principal component analysis and correlation analysis showed that there were significant differences in gene expression patterns at different developmental stages. Upset results showed that 46 248 unigenes were co-expressed in four stages, and 414, 445, 400 and 389 unigenes were specifically expressed in 0, 8,14 and 28 days, respectively. Gene Ontology functional annotation showed that the differentially expressed genes were mainly involved in nsaturated fatty acid biosynthetic process, nuclear body and oxidoreductase activity. Encyclopedia of Genes and Genomes metabolic pathway showed that differentially expressed genes were mainly involved in peroxisome, mitogen-activated protein kinase signaling pathway-plant, plant hormone signal transduction, ribosome, biosynthesis of unsaturated fatty acid, circadian rhythm-plant and other metabolic pathways. In the process of P. ginseng seed dormancy release, multiple biological processes, such as unsaturated fatty acid biosynthesis and plant hormone signal transduction, are required to coordinate regulation, which constitutes a complex dormancy release regulation network. Transcriptome analysis and differential gene screening of P. ginseng seeds at different sand storage time laid a foundation for the analysis of P. ginseng seed dormancy release mechanism and molecular breeding.

Value of brain-expressed X-linked family genes in the diagnosis and prognosis prediction of pan-cancer / 肿瘤研究与临床

Objective:To investigate the differential expression of brain-expressed X-linked (BEX) family genes in pan-cancer and its value in diagnosis and prognosis of pan-cancer.Methods:RNA sequencing (RNA-seq) data, survival data, immune subtypes, the stem cell scores based on RNA and DNA methylation of 33 different tumors from The Cancer Genome Atlas (TCGA) database were downloaded from the online database of University of California, Santa Cruz (UCSC Xena) on April 10, 2022. The limma package of R software (V.4.2.0) was used to analyze the expression of BEX family genes in the TCGA database. The differential expression of BEX family genes in pan-cancer tissues and normal tissues was compared by using Wilcox test. Pan-cancer patients were divided into high expression group and low expression group according to the median expression level of BEX family genes; Kaplan-Meier survival analysis was used to evaluate the relationship between the expression of BEX family genes and the overall survival (OS) of patients; Cox proportional risk model was used to analyze the effect of the expression of BEX family genes on OS in pan-cancer patients and then the forest map was drawn. The correlation of the expression of BEX family genes with tumor microenviroment and tumor stem cells in pan-cancer patients was analyzed based on the correlation index Cor value. Spearman correlation analysis was used to analyze the correlation between the expression of BEX family genes and tumor microenviroment and cancer stem cell index in gastric cancer tissues. The RNA-seq of different tumor cell lines and drug sensitivity data download from the CellMiner database were used to analyze the correlation between the expression of BEX family genes and drug sensitivity. The correlation of pan-cancer and gastric cancer immune subtypes with the expression of BEX family genes was analyzed by using Kruskal test.Results:BEX3 was highly expressed in pan-cancer tissues in TCGA database, BEX2 and BEX4 were moderately expressed in pan-cancer tissues, and BEX1 and BEX5 were relatively low expressed in pan-cancer tissues. The expressions of BEX2, BEX3 and BEX4 were the highest in cholangiocarcinoma, the expression of BEX5 was the highest in endometrial neoplasms, and the expression of BEX1 was the highest in invasive breast cancer. Compared with normal tissue samples, the expressions of BEX family genes were up-regulated or down-regulated in various cancers (all P < 0.05). Survival analysis showed that the expressions of BEX family genes were associated with the OS of various cancers. Some tumor patients with high expressions of BEX1, BEX3, BEX4 and BEX5 had better OS compared with those with low expressions, and the differences were statistically significant (all P < 0.05). Other patients with high expression of BEX family genes had worse OS compared with those with low expressions, and the differences were statistically significant (all P < 0.05). Cox regression analysis showed that the high expression of BEX1 for stomach neoplasms; the high expression of BEX2 for acute myeloid leukemia, thymoma and endometrial neoplasms; the expression high of BEX3 for squamous cell carcinoma of head and neck,sarcoma, stomach neoplasms and endometrial neoplasms; the high expression of BEX4 for rectal adenocarcinoma, stomach neoplasms and endometrial neoplasms; the high expression of BEX5 for renal suspicious cell carcinoma and thymoma were risk factors for OS (all P < 0.05).The expression of BEX family genes was negatively correlated with the stromal score of most cancers (all P < 0.05), and positively correlated with the stem cell score (all P < 0.05). The expression of BEX family genes was negatively correlated with cancer stem cell index of gastric cancer ( P < 0.05), and was positively correlated with matrix score and estimated total score (all P < 0.05). Among different tumor cell lines in CellMiner database, BEX family genes were closely related to drug resistance of vemurafenib (Cor = -0.368, P = 0.004), Kahalide f (Cor = -0.391, P = 0.002), O-6-benzylguanine (Cor = -0.375, P = 0.003) and other drugs. All genes in the BEX family were related to the immune subtypes of pan-cancer and were highly expressed in C5 subtype (all P < 0.05).For gastric cancer, all genes showed high expression in the C3 subtype (all P < 0.05), except BEX5 ( P = 0.24). Conclusions:The expression of BEX family genes is closely related to the prognosis of pan-cancer patients, and has an impact on the tumor microenvironment, cancer stem cells and drug sensitivity. BEX family genes may be potential biomarkers for diagnosis and prognosis of pan-cancer.

Tendon manipulation based on meridian tendon theory can improve the treatment of knee osteoarthritis / 中华物理医学与康复杂志

Objective:To observe any effect of tendon manipulation on the joint pain, joint motion and gait of persons with knee osteoarthritis (KOA).Methods:Sixty-one KOA patients were randomly divided into an observation group ( n=31) and a control group ( n=30). Both groups received ultrasonic physiotherapy and exercise trai-ning (including quadriceps femoris training and heel raising training), while the observation group was additionally provided with daily tendon manipulation, five times a week for 3 weeks. Before and after the treatment, knee pain (using a visual analog scale (VAS)), motor function (using the Western Ontario and McMaster University (WOMAC) osteoarthritis index scale), step length, gait speed and the double support phase ratio were evaluated in both groups using three-dimensional gait analysis equipment. Results:After the treatment the average VAS scores, as well as the joint pain, stiffness and dysfunction and the total WOMAC scores of both groups had decreased significantly. There was significant improvement in the average stride length, walking speed and the proportion of double support phase among the observation group, and the latter two measurements had also improved significantly in the control group. After the intervention, the average pain, WOMAC scores and gait descriptors of the observation group were significantly superior to the control group′s results.Conclusion:Tendon manipulation can usefully supplement routine rehabilitation in the treatment of KOA, improving walking efficiency and thus life quality.

Correlating nerve conduction studies with cross-sectional area measured using ultrasound in patients with neuromuscular disease / 中华神经科杂志

Objective:To determine whether there is a correlation between the cross-sectional area (CSA) and the parameters as measured on nerve conduction studies.Methods:Twenty-one patients with neuromuscular diseases in Beijing Tiantan Hospital from March 3, 2022 to May 4, 2023 underwent ultrasound measurement of the CSA of the median nerves and ulnar nerves at the wrist, elbow and the upper arm, followed by nerve conduction studies (NCS). A linear regression model was performed to compare NCS and CSA.Results:A total of 180 sets of motor nerve conduction velocity (MCV) and CSA at the different sites including 102 sets of median nerve and 78 sets of ulnar nerve, 220 sets of compound muscle action potential (CMAP) amplitude and CSA at the different sites including 104 sets of median nerve and 116 sets of ulnar nerve, 60 sets of sensory nerve conduction velocity (SCV) and CSA and sensory nerve action potential (SNAP) amplitude and CSA at the wrist including 32 sets of median nerve and 28 sets of ulnar nerve were recorded. The linear correlation between MCV and CSA was statistically significant both in median nerve ( r2=0.10,adjusted r2=0.09, P=0.001) and in ulnar nerve ( r2=0.18,adjusted r2=0.17, P<0.001).When CSA>10 mm 2, the linear correlation between CMAP amplitude and CSA was statistically significant both in median nerve ( r2=0.09,adjusted r2=0.08, P=0.024) and ulnar nerve ( r2=0.19,adjusted r2=0.17, P=0.004). The correlation between CMAP and CSA was not statistically significant when CSA≤10 mm 2. And the correlations between SCV and CSA and between SNAP and CSA were not statistically significant. Conclusions:CSA can better show the characteristics of changes in motor nerve conduction especially in motor conduction velocity. It is suggested that its application prospect in demyelinating peripheral neuropathy with motor nerve damage may be more extensive.

Research progress on the common pathogenesis of Parkinson′s disease and rapid eye movement sleep behavior disorder / 中华神经科杂志

Parkinson′s disease (PD) is one of the neurodegenerative diseases with high incidence in middle-aged and elderly people, and its prodromal stage lasts for several years to decades, markers of disease progression in prodromal stage are important basis for early recognition and diagnosis of PD. Current studies have shown that rapid eye movement sleep behavior disorder (RBD) is the specific clinical prodromal symptoms of PD, and has some of the same mechanisms as PD. Part of the same mechanisms develop regularly in the process of RBD converting to PD, which may produce valuable prodromal markers of PD. This paper reviews the common mechanisms of PD and RBD, in order to provide some ideas for the early clinical diagnosis and treatment of PD.

Clinical efficacy and influencing factors of mild therapeutic hypothermia for influenza-associated encephalopathy/encephalitis in children with different center temperatures / 中国热带医学

@#Abstract: Objective To investigate the clinical outcomes and influencing factors of mild therapeutic hypothermia for influenza-associated encephalopathy/encephalitis (IAE) in children with different center temperatures, and to provide ideas and references for new mild therapeutic hypothermia scheme. Methods　A total of 115 hospitalized children with IAE who were scheduled to receive mild therapeutic hypothermia in Zhongshan Hospital Affiliated to Xiamen University from January 2019 to February 2022 were collected as subjects. They were randomly divided into two groups, namely, the 33 ℃ group (n=60) and the 35 ℃ group (n=55). The clinical features and clinical outcomes of the two groups were analyzed. Univariate and multivariate logistic regression analysis was performed for 6-month to investigate the factors affecting neurological disability. Results　The baseline indicators after treatment, such as Glasgow Coma Scale (GCS) score, cerebrospinal fluid total protein (CSF-TP), CSF lactate dehydrogenase (CSF-LDH), lymphocyte (Lym), creatine kinase-MB (CK-MB), LDH, and neuron-specific enolase (NSE), revealed no significant differences between the two groups before treatment or after treatment (P>0.05). There was no significant difference between the two groups after treatment in the clinical outcomes including GCS score D-value, time of hospitalization, 6-month neurological disability rate and mRS score, CSF-TP D-value, CSF-LDH D-value, Lym D-value, CK-MB D-value, LDH D-value, NSE D-value, improvement rate of EEG and MRI (P>0.05). Univariate and multivariate logistic regression analyses [OR=1.185, 95%CI (1.026~1.369), P=0.021] indicated that the delay of the onset of mild therapeutic hypothermia treatment was an independent risk factor for neurological disability in children with IAE after mild therapeutic hypothermia treatment of 6 months. Conclusion　There was no significant difference in the clinical outcomes between 33 ℃ and 35 ℃ mild therapeutic hypothermia for children with IAE. Therefore, mild therapeutic hypothermia for children with IAE may not require a strict requirement. Timely receipt of mild therapeutic hypothermia is a key measrue to reduce the risk of neurological disability in children with IAE.

Evaluation of health warning labels for commercial locations vending sugar-sweetened beverages / 环境与职业医学

Background Long-term excessive consuming sugar-sweetened beverages have a negative impact on health. In order to decrease the consumption of sugar-sweetened beverages and create a healthy food environment, the Health Commission of Shenzhen Municipality pioneered to enforce health warning labels presented in commercial locations vending sugar-sweetened beverages based on relevant provisions of the Health Regulations of Shenzhen Special Economic Zone，but its effect has not yet been evaluated. Objective To evaluate the impact of presenting health warning labels in commercial locations vending sugar-sweetened beverages in Shenzhen. Methods A multi-stage stratified sampling method was used to randomly select one street in each of the 10 districts (excluding the Shenzhen Shantou Special Cooperation Zone) of Shenzhen followed by a convenience sampling to select sampling sites to conduct an undercover investigation on the presentation of health warning labels for sugar-sweetened beverages in six different types of venues (n=232) such as shopping malls, ordinary supermarkets/convenience stores, self-service vending machines, catering service places, medical institutions, and venues serving minors' education and activities. At the same time, 238 site managers, 1002 adult consumers, and 7396 child and adolescent consumers were interviewed. Results Among 213 commercial locations vending sugar-sweetened beverages, the rate of health warning label installation was 26.3%, with the highest installation rate in shopping malls (55.0%). Among site managers, 47.8% were aware that commercial locations were required to install health warning labels, and 50.0% were aware of the standards for setting up health warning labels. The higher the awareness of relevant regulations, the higher the rate of installation of health warning labels. More than half of site managers (55.3%) believed that after installing health warning labels, the sales of sugar-sweetened beverages and sugar-sweetened beverages in large-volume packages had decreased compared to the same period in previous years. Most of the interviewed consumers indicated that if they saw the health warning labels for sugar-sweetened beverages, they would buy less, give up purchasing, or choose low-sugar or sugar-free beverages, and also discourage their family members or friends from drinking such beverages. Compared with participants without awareness of the health warning labels, both adult and child and adolescent consumers with awareness of the health warning labels believed that the installation is beneficial to their good eating habits and reported a higher proportion of discouraging family members or friends from drinking such beverages, with a lower frequency of consuming sugar-sweetened beverages. Conclusion Health warning labels for sugar-sweetened beverages have a significant effect on promoting behavior changes, and both site managers and citizens have a high level of support for them. However, in view of the low voluntary compliance rate of commercial locations and the installation rate of health warning labels, the publicity and enforcement of the Health Regulations of Shenzhen Special Economic Zone should be enhanced.

As for the overall clinical efficacy，the VAS score was （5.13±0.93） score before treatment and （2.22±1.18） score after treatment （P<0.05），with an overall average decrease of （2.91±1.14） score， and the average decrease in the single-use group was （2.76±1.43） score， which was lower than that in the combined-use group ［（3.12±1.36） score，（P<0.01）］. The WOMAC score was （31.05±11.84） score before treatment and （13.55±9.91） score after treatment （P<0.05）. The overall average decrease was （17.50±11.79） score， and the average decrease in the single-use group and combined-use group was （16.39±11.14） score and （19.08±12.50） score，respectively （P<0.01）. The patients with KOA>grade Ⅱ accounted for 91.34%（1 308/1 432） and 93.55%（942/1 007） in the single-use group and combined-use group，respectively （χ2=80.026，P<0.05）. A total of 43.37%（621/1 432） of the patients in the single-use group had other complications，lower than that in the combined-use group ［54.92%（553/1 432），（χ2=20.087，P<0.01）］. ConclusionMore than half of the patients with KOA in the remission stage are treated with Tenghuang Jiangu tablets alone，and the combination therapy is mainly applied in patients with severe conditions or other complications. In relieving knee joint pain and improving joint stiffness and joint function，both the Tenghuang Jiangu tablets alone and the combination therapy are effective.

Meta-analysis of Effect of Tripterygium wilfordii Polyglycoside Tablets Combined with Methotrexate and/or Leflunomide on Autoantibodies in Rheumatoid Arthritis / 中国实验方剂学杂志

ObjectiveTo evaluate the effect of Tripterygium wilfordii polyglycoside tablets （TWPT） combined with conventional synthetic disease-modifying antirheumatic drugs （csDMARDs） including methotrexate （MTX） and/or leflunomide （LEF） on autoantibodies in rheumatoid arthritis （RA） patients. MethodPubMed， EMBASE， Web of Science， Cochrane Library， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched for randomized controlled trials （RCTs） of TWPT combined with MTX and/or LEF in the treatment of RA patients from database inception to December 1， 2021. Primary outcome indicators included rheumatoid factor （RF） and anti-citrullinated protein antibody （ACPA）， and secondary outcome indicators included immunoglobulin （IgA， IgG， and IgM） and adverse drug events （ADE）. ResultThirty-one RCTs， involving 2 643 adult patients， were included， including 20 RCTs of TWPT combined with MTX， 10 of TWPT combined with LEF， and one of TWPT combined with MTX and TWPT. The follow-up time ranged from two weeks to 13 months. Compared with csDMARDs alone， TWPT combined with other drugs significantly improved serum RF of RA patients ［SMD=-2.45， 95% CI ［-2.97， -1.93］， P<0.000 01］， anti-CCP ［SMD=-1.41， 95% CI （-2.35， -0.48）， P=0.003］， IgM ［SMD=-1.90， 95% CI （-3.03， -0.76）， P=0.001］， and IgA ［SMD=-1.18， 95% CI （-2.23， -0.12）， P=0.03］. There were no significant effects on IgG ［SMD=-1.02， 95% CI （-2.04， 0.01）， P=0.05］ and ADE ［RR=0.87， 95% CI （0.66， 1.15）， P=0.32］. ConclusionThe results of this study show that compared with csDMARDs alone， TWPT combined with csDMARDs can effectively improve the levels of autoantibodies in RA patients without increasing the incidence of ADE. However， due to the limited quality and quantity of the included RCTs， the relevant conclusions are only used as a reference for the clinical diagnosis and treatment of RA， and more high-quality studies are still needed to further confirm their efficacy.
