BACKGROUNDIgA nephropathy (IgAN) is the most common primary glomerular disease. Transforming growth factor β1 (TGFβ1) plays an important role in pathogenesis of IgAN. Associations between the polymorphisms of TGFβ1 gene and the risk of IgAN remained inconsistent. A meta-analysis was conducted to investigate the association between polymorphisms in the TGFβ1 gene and IgAN susceptibility.

METHODSDatabases including Pubmed, EMBASE, ISI, et al. were searched to find relevant studies. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the strength of associations.

RESULTSTen studies involving 1770 cases and 1953 controls were included. Significant association between C509T polymorphism and IgAN risk was observed (OR 1.42, 95% CI 1.12-1.81, P = 0.0004; I(2) = 0%) in Caucasians by the overdominant model (CT vs. CC + TT), but no significant association was found (P = 0.200) in Asians by the dominant model (CC + CT vs. TT). Significant association between T869C polymorphism and IgAN susceptibility was found (OR 1.21, 95% CI 1.02-1.44, P = 0.030) in overall populations by the dominant model (TT + TC vs. CC). Subgroup analysis found T allele of T869C polymorphism was associated with IgAN susceptibility in Caucasians (P = 0.030), but not in Asians (P = 0.290).

CONCLUSIONBoth heterozygotes of C509T polymorphism and T allele of T869C polymorphism in TGFβ1 were associated with the risk of IgAN in Caucasians, but not in Asians.

Objective To discuss the design and application effects of the electronic nursing records system.Methods The electronic nursing records system with comprehensive functions including resource sharing and importing, nursing documents typing in, quality control and dictionary management, was designed based on the clinic and implemented in the hospital. Qualification rates of nursing documents, incidences of fall and pressure ulcer in high-risk population, and patient's satisfaction after the implementation from 2014 to 2016 were collected to evaluate the application effect.Results Qualification rate of nursing documents increased from 96.37% to 97.98%; incidence of fall in high-risk population decreased from 0.35% to 0.08%; incidence of pressure ulcer in high-risk population decreased from 3.64% to 2.85%; and patient's satisfaction increased from 93.90% to 96.53%.Conclusions The electronic nursing records system not only saves the writing time, standardizes nursing records, increases the qualification rate of nursing documents, but also can decrease the incidence of nursing adverse events and increase the patient's satisfaction. However, there are still some defects in the system that require the improvement.

Chinese patent medicine (CPM) is an important part of traditional and Chinese medicine (TCM). Its quality has direct impact on the safety and effectiveness of clinical use. The quality standard is the pivotal approach to guarantee the quality of CPM. Due to the complex material basis, multitudinous quality influencing factors and unveiled active ingredients, dose-effect relationship and action mechanism, the investigation on quality standard faces many difficulties. This paper surveys the current quality status of CPM and the general situation of CPM standards. At present, the dosing problem has the crucial impact on the quality of CPM. The current quality standard system of CPM is confirmed and the limitations are indicated. Based on the above analysis, the principles and considerations on investigation of quality standard are proposed as follows: ① Adhere to safety as the bottom line, strengthen the risk-control ability of the standard of CPM; ② Adhere to theory of TCM and comprehensive quality, improve the integrative control level of the CPM standard; ③ Emphasize technological development and innovation, promote the quality control competence of CPM standard; ④ Facilitate planning and coordination, optimize the management of the CPM standard system; ⑤ Reinforce investigation on evaluation method, develop grade evaluation standard, accelerate high-quality development of CPM. Finally, the future perspective on investigation of CPM quality standard is prospected.

Heavy metals and other harmful elements in traditional Chinese medicines inflict serious damage on public health. Therefore, risk assessment of Chinese raw materials has gained increasing attention. To date, few reports have been published on the health risk assessment of heavy metals and harmful elements in Chinese patent medicines. To gain a comprehensive understanding of heavy metals and other harmful elements in Chinese patent medicines and to establish proper limits, residual Pb, Cd, As, Hg, Cu and Cr in 15 054 samples of 295 drugs was analyzed with regard to distribution and variation between elements and dosage forms. In addition, in accord with procedures including hazard identification, hazard characterization, exposure assessment and risk characterization, basic procedures and specific parameters for risk assessment of heavy metals and harmful elements in Chinese patent medicines were clarified based on the health risk assessment of 14 787 samples and 276 drugs. A method and equation for establishing residual limits is proposed. The results show that content and target hazard quotients (THQs) of the investigated elements in all samples showed a skewed distribution approaching 0. Content of Pb, As, Cu, Hg, Cd or Cr in the samples exceeded 100 mg·kg^-1 and the content of Pb, As, or Cu in individual samples exceeded 1 000 mg·kg^-1. THQs of 586 samples and four drugs were above 1. We believe that the health risk of Hg, Pb and As in Chinese patent medicines with dosage forms of pill, capsule, tablet and powder, especially those in raw powder preparations, warrant concern.

OBJECTIVE: To develop an automated chimeric analysis and reporting platform based on short tandem repeat (STR) and capillary electrophoresis methods for allogeneic hematopoietic stem cell transplantation (allo-HSCT) so as to improve work efficiency. METHODS: Apache, MySQL, PHP and HTML5 were used to build the database and interface. The STR locus geno typing and chimeric analysis logic and flow were set up on the basis of STR rules and capillary electrophoresis. STR genotyping and 194 times of chimeric testing data of 100 patients after allo-HSCT were used to test the platform for automatic STR locus genotyping, chimeric calculation and report generation. RESULTS: The established platform could realize the functions of STR locus customization, STR genotype determination, automatic chimeric analysis, and detection information database management, which can automatically generate an integrated report including multiple sequential chimeric results and trend graphs for the same patient and can be accessed and used simultaneously by different users through different browser interfaces. The results of automated analysis by the platform are completely consistent with that of manual analysis by experienced technicians, and the possibility of manual analysis error is reduced through automation. The time required for automatic analysis using this platform is approximately 1/6-1/5 of manual analysis. CONCLUSION The automatic analysis platform built in this study is operation stable and reliable in analysis results, which can improve work efficiency and report connotation, thus worthing popularized and applicable.

Retrograde adeno-associated viruses (AAVs) are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks. However, few retrograde AAV capsids have been shown to offer access to cortical projection neurons across different species and enable the manipulation of neural function in non-human primates (NHPs). Here, we report the development of a novel retrograde AAV capsid, AAV-DJ8R, which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques. In addition, intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations. Moreover, AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen. These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
