Comparison of HPLC fingerprints and determination of main components of Viticis Fructus from different species / 中国中药杂志

In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.

Hyperglycemia-Suppressed SMARCA5 Disrupts Transcriptional Homeostasis to Facilitate Endothelial Dysfunction in Diabetes

Background@#Dysfunction of vascular endothelial cells (ECs) plays a central role in the pathogenesis of cardiovascular complications in diabetes. SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily A member 5 (SMARCA5) is a key regulator of chromatin structure and DNA repair, but its role in ECs remains surprisingly unexplored. The current study was designed to elucidate the regulated expression and function of SMARCA5 in diabetic ECs. @*Methods@#SMARCA5 expression was evaluated in ECs from diabetic mouse and human circulating CD34+ cells using quantitative reverse transcription polymerase chain reaction and Western blot. Effects of SMARCA5 manipulation on ECs function were evaluated using cell migration, in vitro tube formation and in vivo wound healing assays. Interaction among oxidative stress, SMARCA5 and transcriptional reprogramming was elucidated using luciferase reporter assay, electrophoretic mobility shift assay and chromatin immunoprecipitation. @*Results@#Endothelial SMARCA5 expression was significantly decreased in diabetic rodents and humans. Hyperglycemia-suppressed SMARCA5 impaired EC migration and tube formation in vitro, and blunted vasculogenesis in vivo. Contrarily, overexpression of SMARCA5 in situ by a SMARCA5 adenovirus-incorporated hydrogel effectively promoted the rate of wound healing in a dorsal skin punch injury model of diabetic mice. Mechanistically, hyperglycemia-elicited oxidative stress suppressed SMARCA5 transactivation in a signal transducer and activator of transcription 3 (STAT3)-dependent manner. Moreover, SMARCA5 maintained transcriptional homeostasis of several pro-angiogenic factors through both direct and indirect chromatin-remodeling mechanisms. In contrast, depletion of SMARCA5 disrupted transcriptional homeostasis to render ECs unresponsive to established angiogenic factors, which ultimately resulted in endothelial dysfunction in diabetes. @*Conclusion@#Suppression of endothelial SMARCA5 contributes to, at least in part, multiple aspects of endothelial dysfunction, which may thereby exacerbate cardiovascular complications in diabetes.

Objective:To explore the prevalence rate of restless leg syndrome (RLS) and its related influencing factors in patients with maintenance hemodialysis (MHD) in Anhui province.Methods:It was a cross-sectional study, including regular MHD patients in blood purification centers of 27 hospitals in southern, central and northern Anhui province from January to March 2020. The investigation included general demographic characteristics, primary diseases, complications, dialysis-related conditions and drug use. According to the presence or absence of RLS, the patients were divided into RLS group and non-RLS group, and the differences of clinical data between the two groups were compared. Logistic regression analysis method was used to analyze the influencing factors of RLS.Results:The study included 3 025 MHD patients, aged (54.8±12.8) years old, with 1 819 males (60.1%) and 1 206 females (39.9%). The dialysis age was (5.5±3.8) years. The prevalence rates of RLS in MHD patients were 8.8% (265/3 025), of which 13.7% (77/561), 7.7% (88/1 145) and 7.6% (100/1 319) in southern, central and northern Anhui province, respectively. The prevalence rates of RLS in MHD patients in secondary and tertiary hospitals were 9.5% (55/577) and 8.6% (210/2 448), respectively. Proportion of hypertension, dialysis age, intact parathyroid hormone, alkaline phosphatase, 25(OH)D3, and proportions of secondary hyperparathyroidism, erythropoietin use, iron supplements, active vitamin D use, calcimimetic use, dialysis blood flow <250 ml/min and low-flux dialyzers in RLS group were higher than those in non-RLS group, while hemoglobin level and proportions of non-calcium-phosphorus binders and high-flux dialyzers were lower than those in non-RLS group (all P<0.05). Multivariate logistic regression analysis results showed that long dialysis age ( OR=1.188, 95% CI 1.031-1.369, P=0.017) and high alkaline phosphatase ( OR=1.007, 95% CI 1.001-1.013, P=0.047) were correlated with a higher risk of RLS in MHD patients. Conclusions:The prevalence rate of RLS in MHD patients in Anhui province is 8.8%. The prevalence rates of RLS in MHD patients in southern, central and northern Anhui province are 13.7%, 7.7% and 7.6%, respectively. The prevalence rate of RLS in secondary and tertiary hospitals are 9.5% and 8.6%, respectively. Long dialysis age and high alkaline phosphatase are associated with a high risk of RLS in MHD patients.

TRPV4-induced Neurofilament Injury Contributes to Memory Impairment after High Intensity and Low Frequency Noise Exposures / 生物医学与环境科学（英文）

OBJECTIVE@#Exposure to high intensity, low frequency noise (HI-LFN) causes vibroacoustic disease (VAD), with memory deficit as a primary non-auditory symptomatic effect of VAD. However, the underlying mechanism of the memory deficit is unknown. This study aimed to characterize potential mechanisms involving morphological changes of neurons and nerve fibers in the hippocampus, after exposure to HI-LFN.@*METHODS@#Adult wild-type and transient receptor potential vanilloid subtype 4 knockout (TRPV4-/-) mice were used for construction of the HI-LFN injury model. The new object recognition task and the Morris water maze test were used to measure the memory of these animals. Hemoxylin and eosin and immunofluorescence staining were used to examine morphological changes of the hippocampus after exposure to HI-LFN.@*RESULTS@#The expression of TRPV4 was significantly upregulated in the hippocampus after HI-LFN exposure. Furthermore, memory deficits correlated with lower densities of neurons and neurofilament-positive nerve fibers in the cornu ammonis 1 (CA1) and dentate gyrus (DG) hippocampal areas in wild-type mice. However, TRPV4-/- mice showed better performance in memory tests and more integrated neurofilament-positive nerve fibers in the CA1 and DG areas after HI-LFN exposure.@*CONCLUSION@#TRPV4 up-regulation induced neurofilament positive nerve fiber injury in the hippocampus, which was a possible mechanism for memory impairment and cognitive decline resulting from HI-LFN exposure. Together, these results identified a promising therapeutic target for treating cognitive dysfunction in VAD patients.

Objective: To analyze the migration of the HIV/AIDS cases and related factors in Liangshan Yi autonomous prefecture (Liangshan). Methods: According to HIV/AIDS Comprehensive Response Information Management System of China Information System for Disease Control and Prevention, a total of 28 772 HIV/AIDS cases who had follow-up records in Liangshan in 2020 were included in the survey. The migration of the HIV/AIDS cases was described and the related factors were analyzed using multiple logistic regression models, and the migration destinations of the HIV/AIDS cases were mapped. Results: Among the 28 772 HIV/AIDS cases, 20.89% (6 010/28 772) had migration in 2020. Multivariate logistic regression analysis showed that among the HIV/AIDS cases, the migration related factors included being aged 15-24 years (compared with being aged 0-14 years, OR=2.74, 95%CI:2.04-3.69) and ethnic group (compared with Han ethnic group, OR=2.44, 95%CI:2.19-2.72), having education level of junior high school (compared with having education level of primary school or below, OR=1.25, 95%CI:1.14-1.38), being unmarried (compared with being married, OR=1.29, 95%CI:1.20-1.39), being engaged in business services (compared with being engaged in farming, OR=1.96, 95%CI:1.31-2.92), receiving antiviral treatment <1 year (compared with receiving antiviral treatment >3 years, OR=1.42, 95%CI:1.26-1.61), having recent CD4+T lymphocytes (CD4) counts >500 cells/μl (compared with having recent CD4 counts <200 cells/μl, OR=1.15, 95%CI:1.03-1.29). The geographical distribution maps showed that among all cities in Sichuan, Xichang (13.26%, 797/6 010) and Chengdu (10.12%,608/6 010) were the main migration destinations of the HIV/AIDS cases, and the provinces outside Sichuan where the HIV/AIDS cases would like to migrate to were mainly Guangdong (18.19%, 1 093/6 010) and Zhejiang provinces (7.67%, 461/6 010) in 2020. The HIV/AIDS cases who migrated where Liangshan, within Sichuan province, and to other provinces accounted for 27.67% (1 663/6 010), 15.34% (922/6 010) and 56.99% (3 425/6 010), respectively. Conclusions: More attention should be paid to the mobility characteristics and the classification management of HIV/AIDS cases according to their characteristics in Liangshan. Timely access to information on changes in the place of work and residence of HIV/AIDS cases should be warranted when they have migration. Good referrals and management for mobility of HIV/AIDS cases in different places should be made to reduce loss to follow-up and improving interventions.

Interpretation of the international expert recommendations of clinical features to prompt referral for diagnostic assessment of cerebral palsy / 中国当代儿科杂志

Under the guidance and support of national policies in recent years, the community medical system has been developed rapidly, among which primary child healthcare is carried out routinely in community hospitals, greatly alleviating the pressure of specialized pediatric hospitals and departments of pediatrics in secondary and tertiary general hospitals. However, due to the lack of professional training for primary child healthcare personnel in community medical institutions, early symptoms of children with cerebral palsy cannot be identified and so children with cerebral palsy are often unable to receive early diagnosis and intervention, which may affect their prognosis. An article about international expert consensus and recommendations on early identification and referral of cerebral palsy in community medical institutions was published in

Mitral valve repair included implantation of artificial valve ring, implantation of artificial tendon, posterior leaflets sliding, partial resection of posterior leaflets (excluding sliding), valve leaflets folding, tendon folding, papillary muscle splitting and annular valve contraction (excluding artificial valve ring implantation). The technique of mitral valve repair, early clinical results and follow-up echocardiographic data were analyzed. Results    All the patients successfully completed the mitral valve repair. The mean time of aortic occlusion was 73.2±17.4 min, and cardiopulmonary bypass time was 99.5±19.8 min. At the same time, 4 patients received tricuspid valve repair and 1 funnel chest correction. There was no reoperation in perioperative period. The 1-year and 5-year survival rates were 100.0% and 100.0%, respectively. The incidence of below moderate mitral regurgitation was 90.0% at postoperative 1 year and 72.0% at postoperative 5 years. Conclusion    For the young children who have Barlow disease and mitral regurgitation, considering the characteristics of heavy lesions, small operation space, and the need to meet the growth and development of valve, it is suggested to adopt the surgical techniques different from those of older children, such as valve ring retraction and tendon folding, if necessary, to adopt "edge to edge" suture, which can shorten aortic occlusion time and achieve good early effects, and its long-term effects still need further follow-up observation. Mitral valvuloplasty technique for Barlow disease similar to that of adults can be used in older children, including implantation of artificial valve ring and implantation of artificial tendon, etc.

Progress in low anterior resection syndrome of rectal cancer / 国际外科学杂志

With the development of surgical instruments and improved surgical techniques, more and more patients with low rectal cancer can get the effect of the radical cure while preserving the anus. Still, nearly 60%-90% of patients will undergo low anterior resection after surgery Syndrome (down anterior resection syndrome, LARS) LARS can seriously affect patients′ quality of life after surgery. This article will explain the concept, symptoms, possible pathogenesis, prevention, and treatment measures of LARS and provide help for the diagnosis, treatment and prevention of LARS.

Interpretation of ASTCT Consensus Responses by Chimeric Antigen Receptor T Cell Therapy CRS/ICANS--Review / 中国实验血液学杂志

Chimeric antigen receptor T cell (CAR-T) therapy was awarded as the largest research breakthrough in 2017 by the American Society of Clinical Oncology, at present, it is rapidly becoming the most promising new treatment for hematological malignancies. However, this therapy also produces a new challenge: toxic adverse events such as cytokine release syndrome (CRS) and neurotoxicity, partial of them can bring death to the patients. The incidence and severity of the above toxic events in different multi-center trial reports are also different, which may be attributed to the different in the considerably variable assessment and grading of toxicities between clinical trials and across institutions. The ASTCT published at 2018 advanced the consensus grading for cytokine release syndrome and neurologic toxicity associated with immune effector cells, it was focusing on CRS and neurotoxicity associated with immune effector cells. In order to provide reference for the development of relevant work in this field and the formulation of security strategies in our country, the main content of the consensus was summarized briefly.

Complanatoside A and complanatoside B in rats administered with raw and salt-processed Astragali Complanati Semen: a pharmacokinetics study / 中国中药杂志

An UPLC-MS/MS method was developed to simultaneously determine complanatoside A and complanatoside B in rat plasma with rutin as the internal standard and applied to examine the effect of salt-processing on pharmacokinetics of these two flavonoid glycosides. The pharmacokinetic parameters were estimated using DAS 3.2.6 and subjected to independent sample t-test with SPSS 23.0. No significant difference in T_(max) of complanatoside B was observed between the raw and processed groups; however, in the processed group, C_(max) and AUC_(0-12 h) of complanatoside B increased obviously(P<0.05), while MRT_(0-12 h) decreased from(3.34±0.44) h to(1.81±0.36) h(P<0.05). C_(max) [(14.72±11.13) μg·L~(-1)] and MRT_(0-24) [(3.93±0.26) h] of complanatoside A in the raw group were statistically different from those [(35.64±21.99) μg·L~(-1),(1.43±0.24) h] in the processed group(P<0.05). As a result, salt-processing can facilitate the in vivo adsorption and accelerate the excretion of complanatoside A and complanatoside B.
