Efficacy of scraping therapy on blood pressure and sleep quality in stage I and II essential hypertension: A systematic review and meta-analysis.

BACKGROUND: Scraping therapy is widely used in treating stage I and II essential hypertension in China. However, there has been no systematic evaluation of the efficacy of scraping therapy on blood pressure and sleep quality in stage I and II essential hypertension. SEARCH STRATEGY: Seven electronic databases (PubMed, Scopus, Cochrane Library, Web of Science, EBSCO, China National Knowledge Infrastructure and Wanfang Data electronic databases) were searched from inception to December 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "scraping therapy," "scraping," "Guasha," "Gua sha," "hypertension," and "high blood pressure" during the database searches. INCLUSION CRITERIA: Randomized controlled trials (RCTs) were included if they recruited patients with stage I and II essential hypertension and included a scraping therapy intervention. The intervention group received antihypertensive drugs and scraping therapy, while the control group only took antihypertensive drugs. DATA EXTRACTION AND ANALYSIS: Review Manager 5.4.0 and STATA 15.1 were used to enter all the relevant outcome variables to conduct the meta-analysis. The quality of the selected RCTs was assessed using the PEDro scale. The sensitivity analysis was carried out by iteratively excluding individual studies and repeating the analysis to determine the stability of the findings and identify any studies with greater influence on the outcome. Subgroup analysis was performed to find the source of heterogeneity. Funnel plots were used to evaluate the publication bias of included studies. RESULTS: Nine RCTs including 765 participants were selected. Meta-analysis showed that scraping therapy combined with medication had an advantage over the use of medication alone in lowering systolic blood pressure (mean difference [MD] = -5.09, 95% confidence interval [CI] = -6.50 to -3.67, P < 0.001) and diastolic blood pressure (MD = -2.66, 95% CI = -3.17 to -2.14, P < 0.001). Subgroup analysis showed that scraping therapy improved sleep quality in middle-aged patients with hypertension, but the efficacy was better in elderly patients (MD = -7.91, 95% CI = -8.65 to -7.16, P < 0.001) than in middle-aged patients (MD = -2.67, 95% CI = -4.12 to -1.21, P = 0.0003). CONCLUSION: The available evidence indicates that scraping therapy has significant effects on patients with stage I and II hypertension, and it improves sleep quality for elderly patients with hypertension better than for middle-aged ones. Scraping therapy can be an adjunctive treatment for stage I and II essential hypertension. However, further high-quality studies are needed to verify its effectiveness and the best therapeutic strategies. Please cite this article as: Zhu, Z, Wang J, Pan, X.

A Data Mining-Based Study on Medication Rules of Chinese Herbs to Treat Heart Failure with Preserved Ejection Fraction.

OBJECTIVE: To summarize the medication rules of Chinese herbs to treat heart failure with preserved ejection fraction (HFPEF) based on data mining and to provide references for clinical utilization. METHODS: The China National Knowledge Infrastructure (CNKI), Wanfang database (Wanfang), VIP database (VIP), Chinese Biomedical Literature (CBM), PubMed, Embase, and Cochrane Library databases were searched from inception to October 2021 to identify relevant literature on treating HFPEF with Chinese herbs. Microsoft Excel 2019 was used to set up a database, and then, association rule analysis and hierarchical cluster analysis were performed by using apriori algorithm and hclust function respectively in R-Studio (Version 4.0.3). RESULTS: A total of 182 qualified papers were included, involving a total of 92 prescriptions, 130 Chinese herbs, and 872 individual herbs prescribed, with an average of 9.5 herbs per prescription. The six most frequently prescribed herbs were Astragali Radix (Huangqi), Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Glycyrrhizae Radix Et Rhizoma (Gancao), Cinnamomi Ramulus (Guizhi), and Ginseng Radix Et Rhizoma (Renshen). There were 35 herbs used more than 5 times, involving 11 efficacy categories. The top three categories were deficiency-tonifying herbs, blood-activating and stasis-removing herbs, and dampness-draining diuretic herbs. The most commonly used herbs were mainly warm and sweet. The primary meridian tropisms were Lung Meridian, Heart Meridian and Spleen Meridian. Association rule analysis yielded 26 association rules, such as Astragali Radix (Huangqi) & Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Cinnamomi Ramulus (Guizhi) & Atractylodis Macrocephalae Rhizoma (Baizhu). Hierarchical cluster analysis yielded four herb classes, and their functions were mainly qi-replenishing and yang-warming, blood-activating and diuresis-inducing. CONCLUSIONS: HFPEF is the syndrome of root vacuity and tip repletion, and its core pathogenesis is "deficiency", "stasis", and "water", with "deficiency" being the most principal, which is closely related to Xin (heart), Fei (Lung), and Pi (Spleen). The treatment of this disease occurs by improving qi, warming yang, activating blood and inducing diuresis. Astragali Radix (Huangqi) with Salviae Miltiorrhizae Radix Et Rhizoma (Danshen) is the basic combination of herbs applied.

Impact of the COVID-19 pandemic on career intention amongst undergraduate medical students: a single-centre cross-sectional study conducted in Hubei Province.

BACKGROUND: Undergraduate medical (UM) students faced the difficulties inherent in medical careers due to the coronavirus (COVID-19) outbreak. Thus, imperative containment measures might affect UM students' career intentions. Information on the factors that may be associated with these students' career change intentions is limited. METHODS: We conducted a cross-sectional survey in August 2020 to investigate the impact of the COVID-19 pandemic on career intention and the associated factors in UM students. Univariate analyses and logistic regression analysis were performed to identify said factors. RESULTS: A total of 2040 medical students from the Hubei University of Medicine were surveyed. Univariate analyses showed that grade, attitude towards healthcare, and the degree of the COVID-19 pandemic's impact on the students' lives were associated with changes in career choice (P<0.05). Logistic regression analysis showed that Grade 2, Grade 5, attitude towards a medical career, and having relatives with a medical background were associated with changes in career choice. The degree of the COVID-19 pandemic's impact was a common and significant factor associated with career preference, career perspective, and ideal workplace. CONCLUSIONS: Changes in career intentions were particularly influenced by grade, attitude towards being a health worker, and the degree of COVID-19's impact on the participants' lives. Treating large-scale public health emergencies rationally, setting up correct views of occupation choice, and building reasonable career planning may reduce the loss of medical talent.

Multi- and transgenerational biochemical effects of low-dose exposure to bisphenol A and 4-nonylphenol on testicular interstitial (Leydig) cells.

Bisphenol A (BPA) and 4-nonylphenol (NP) are well-known endocrine-disrupting chemicals (EDCs) that have been proven to affect Leydig cell (LC) functions and testosterone production, but whether BPA and NP have multi- and transgenerational biochemical effects on Leydig cells (LCs) is unknown. Fourier transform infrared (FTIR) spectroscopy is a powerful analytical technique that enables label-free and non-destructive analysis of the tissue specimen. Herein we employed FTIR coupled with chemometrics analysis to identify biomolecular changes in testicular interstitial (Leydig) cells of rats after chronic exposure to low doses of BPA and NP. Cluster segregations between exposed and control groups were observed based on the fingerprint region of 1800-900 cm-1 in all generations. The main biochemical alterations for segregation were amide I, amide II and nucleic acids. BPA and NP single and co-exposure induced significant differences in the ratio of amide I to amide II compared to the corresponding control group in all generations. BPA exposure resulted in remarkable changes of cellular gene transcription and DNA oxidative damage across all generations. Direct exposure to BPA, NP, and BPA&NP of F0 and F1 generations could significantly decrease lipid accumulation in LCs in the F2 and F3 generations. The overall findings revealed that single or co-exposure to BPA and NP at environmental concentrations affects the biochemical structures and properties of LCs.

Role of the miR-133a-5p/FBXO6 axis in the regulation of intervertebral disc degeneration.

OBJECTIVE: Low back pain is a leading cause of disabilities worldwide, and intervertebral disc degeneration (IVDD)-related disorders have been recognised as one of the main contributors. Nevertheless, the underlying mechanism has not yet been fully understood. The aim of this study was to investigate the role of the miR-133a-5p/FBXO6 axis in the regulation of IVDD. METHODS: RT-qPCR, WB and IHC were performed to assess the expression of FBXO6 in human IVD tissues. Nucleus pulposus (NP) cells were treated with IL-1ß to induce IVDD cellular model. Silence of FBXO6 was achieved using specific siRNAs. CCK-8 assay, flow cytometry, TUNEL assay, RT-qPCR and WB were used to evaluate the role and mechanism of FBXO6 in the process of IVDD. Online tools, GSE datasets and RT-qPCR were used to search the candidate miRNAs targeting FBXO6. The direct binding sites between FBXO6 and miR-133a-5p were further verified by a dual luciferase assay. RT-qPCR, WB and rescue experiments were conducted to identify the regulatory function of miR-133a-5p on the expression of aggrecan, collagen Ⅱ, MMP3, ADAMTS5, IL-6 and COX2. In addition, the role of the NF-κB pathway in regulating miR-133a-5p was studied using lentiviral shRNA, WB and RT-qPCR. RESULTS: Results showed that FBXO6 mainly expressed in the NP tissue of IVD and the expression of FBXO6 decreased with the process of IVDD as well as under IL-1ß stimulation. The silence of FBXO6 led to the decreased expression of aggrecan and collagen Ⅱ and the increased expression of MMP3, ADAMTS5, IL-6 and COX2, which further induced the degeneration of NP cells. The bioinformatic analysis showed that miR-133a-5p was the candidate miRNA targeting FBXO6. miR-133a-5p was upregulated in IVDD tissues and significantly inhibited the expression of FBXO6. The inhibition of miR-133a-5p ameliorated the acceleration of IVDD induced by the silence of FBXO6 in vitro. Moreover, it was demonstrated that IL-1ß regulated the expression of the miR-133a-5p/FBXO6 axis via the NF-κB pathway in NP cells. CONCLUSION: miR-133a-5p was upregulated by IL-1ß to aggravate intervertebral disc degeneration via sponging FBXO6. Inhibiting miR-133a-5p expression or rescuing FBXO6 expression may be promising strategies for the treatment of IVDD. THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE: This study suggests that the miR-133a-5p/FBXO6 axis could regulate NP cells proliferation, apoptosis, synthesis and degradation of extracellular matrix, which provides a promising therapeutic target and strategy for the treatment of IVDD.

[Key points of post-marketing evaluation of classic traditional Chinese medicine prescriptions based on combination of disease and syndrome].

Classic prescriptions, hospital preparations and famous traditional Chinese medicine(TCM) experience prescriptions are the main sources of new drug development and innovation. The multi-components and multi-targets treatment characteristics of TCM are advantages, but at the same time, broad indications, unclear clinical positioning and lack of evidence-based evidence support are the key problems affecting the play of TCM efficacy and restricting its promotion and application. The hot in recent research was to how to break through the bottleneck, precise clinical positioning, highlight the advantages of the classic TCM prescriptions, and complete the transformation from clinical practice, clinical research to clinical evidence, but at the same time, it is also the difficulty. The clinical research model of the combination of disease and syndrome can fully reflect the ancient medical case evidence of classic TCM prescriptions, the historical experience of human used and the characteristics of syndrome differentiation and treatment, and highlight the advantages of Chinese medicine. At the same time, under the modern disease classification system and research mode, is conducive to established the standardized clinical evidence report and evaluation system, is conducive to promote the integration of clinical research evidence, and avoids excessive attenuation of information.

Lateral-anterior lumbar interbody fusion (LaLIF) for lumbar degenerative disease: Technical notes, surgical system, and mid-term outcomes.

BACKGROUND: Many modified lateral lumbar interbody fusion techniques for lumbar degenerative diseases have been described by different authors. However, relatively high rates of vascular injury, peritoneal laceration, and even ureteral injury have been reported. PURPOSE: The objectives of this study were firstly to present the detailed, standardized technical notes and describe the required standard characteristics of the designed surgical system of LaLIF and secondly to evaluate clinical outcomes and highlight the approach-related complications. METHODS: The mini-open LaLIF is described in a step-wise manner. The outcome measures were operative parameters, self-report measures, radiographic measures, and complications within 1 month of surgery. Operative parameters measured included operative time, intraoperative blood loss, and length of hospital stay. The self-report measures include Visual Analogue Scale (VAS), Oswestry disability index (ODI), and Short Form 36 Health Survey (SF-36) score. The radiographic measures including the intervertebral foraminal height (FH), intervertebral disc height (DH), and intervertebral foraminal area (FA) were assessed with plain radiography. The complication profiles were classified into intraoperative and postoperative (up to 1 month). Intraoperative complications were subcategorized into neurologic, vascular, ureteral, peritoneal, and vertebral injuries. Postoperative complications were subcategorized into infection, cage migration, and subsidence. RESULTS: A total of 126 patients who underwent LaLIF between April 2016 and December 2018 â€‹by a senior author were retrospectively reviewed. There were 54 males and 72 females (range 42-89 â€‹years old, average 65 â€‹± â€‹11 years old). The mean follow-up was 20 â€‹± â€‹11 â€‹months (range 6-38 â€‹months). The LaLIF was conducted at 188 levels in 126 patients, with 1 level in 75 cases, 2 levels in 42, 3 levels in 7, and 4 levels in 2 cases. There were 114 patients who underwent stand-alone LaLIF and 12 patients required secondary posterior fixation. The mean operative time, intraoperative blood loss, and length of hospital stay were recorded. The patient-reported outcome scores (VAS, ODI, and SF-36) and radiographic parameters (FH, DH, and FA) demonstrated a significant improvement after surgery and at the last follow-up. There were 25 (19.8%) complications in the 126 patients. The intraoperative complications accounted for 19 cases (15.1%) and postoperative accounted for 6 cases (4.8%). The most frequent complications were neurological injury (6.3%) and temporary psoas injury (6.3%). CONCLUSIONS: The mini-open LaLIF, as a reproducible novel technique, can be performed safely at L2-L5. It is associated with reliable mid-term clinical outcomes and an acceptable complication profile when compared to traditional LLIF due to the advancements in the modified incision site, direct visualization, and usage of strictly vertical trajectory in multiple steps with the specially designed LaLIF system. TRANSLATIONAL POTENTIAL STATEMENT: To make the lateral lumbar fusion process repeatable and also maintain a shallow learning curve, especially for surgeons in the early stages of learning, by using instruments with the required standard characteristics, the standardized surgical steps, modified incision site, vertical trajectory, and the direct visualization during the entire procedure.

Protection against COVID-19 injury by qingfei paidu decoction via anti-viral, anti-inflammatory activity and metabolic programming.

Qingfei Paidu decoction (QFPD), a multi-component herbal formula, has been widely used to treat COVID-19 in China. However, its active compounds and mechanisms of action are still unknown. Firstly, we divided QFPD into five functional units (FUs) according to the compatibility theory of traditional Chinese medicine. The corresponding common targets of the five FUs were all significantly enriched in Go Ontology (oxidoreductase activity, lipid metabolic process, homeostatic process, etc.), KEGG pathways (steroid biosynthesis, PPAR signaling pathway, adipocytokine signaling pathway, etc.), TTD diseases (chronic inflammatory diseases, asthma, chronic obstructive pulmonary Disease, etc.), miRNA (MIR183), kinase (CDK7) and TF (LXR). QFPD contained 257 specific targets in addition to HCoV, pneumonia and ACE2 co-expression proteins. Then, network topology analysis of the five components-target-pathway-disease networks yielded 67 active ingredients. In addition, ADMET estimations showed that 20 compounds passed the stringent lead-like criteria and in silico drug-likeness test with high gastrointestinal absorption and the median lethal dose (LD50 > 1600 mg/kg). Moreover, 4 specific ingredients (M3, S1, X2 and O2) and 5 common ingredients (MS1, MX16, SX1, WO1 and XO1) of QFPD presented good molecular docking score for 2019-nCov structure and non-structure proteins. Finally, drug perturbation of COVID-19 network robustness showed that all five FUs may protect COVID-19 independently, and target 8 specifically expressed drug-attacked nodes which were related to the bacterial and viral responses, immune system, signaling transduction, etc. In conclusion, our new FUNP analysis showed that QFPD had a protection effect on COVID-19 by regulating a complex molecular network with safety and efficacy. Part of the mechanism was associated with the regulation of anti-viral, anti-inflammatory activity and metabolic programming.

Rapid development of tissue bank achieved by International Atomic Energy Agency (IAEA) Tissue Banking Programme in China.

Benefit from training course, SPTB promoted the development of tissue transplantation by ways of training, brochure, advertisement and meeting. Tissue allograft transplantation acquired recognition from clinic and supervision and administration from government. Quality system gradually is developing and perfecting. Tissue allograft transplantation and tissue bank are developing rapidly and healthy.

[Correlation of lumbar disc degeneration and spinal-pelvic sagittal balance].

OBJECTIVE: To elucidate the relationship between spino-pelvic sagittal balance parameters and lumbar intervertebral disc degeneration of each segment through retrospective analysis in lumbar degeneration patients. METHODS: Retrospective analysis was conducted for the follow-up data in 126 patients with lumbar degenerative disease from July 2009 to June 2012. There were 38 cases with whole spine plates and 88 cases with lumbar plates. All of them received magnetic resonance imaging (MRI) scans. Through software Image J, the following spino-pelvic sagittal balance parameters were measured: sagittal vertical axis (SVA, distance between C7 plumb line and posterior upper corner of S1 endplate), thoracic kyphosis (TK, T5-T12 Cobb angle), thoracolumbar kyphosis (TLK, T10-L2 Cobb angle), lumbar lordosis (LL, L1-L5 Cobb angle), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), T1 spino-pelvic inclination (T1-SPI), T9 spino-pelvic inclination (T9-SPI), spino-sacral angle (SSA), spino-pelvic angle (SPA) and C7 tilt (C7T). Based on the grading system of Pfirrmann et al, the intervertebral disc degeneration grades were acquired for each lumbar segment. According to the normal range of previous studies, each spino-pelvic sagittal balance parameter was classified into 3 groups, i.e. Group A (less than normal), Group B (normal) and Group C (more than normal). All statistical analyses were performed to compare the differences of each lumbar segment/intervertebral disc degeneration among groups by one-way ANOVA test via SPSS 18.0. And P-value < 0.05 was deemed significant. RESULTS: PI had a significant impact on the L5/S1 disc degeneration. And L5/S1 disc degeneration had a significant impact on sagittal balance. Among 57 cases of large PI, LL, PT, SS, SVA, C7T, SPA in L5/S1 of mild-to-moderate and severe degeneration groups was 36.91 ± 14.93 and 29.71 ± 11.30 (P = 0.045), 18.82 ± 8.27 and 25.18 ± 10.19 (P = 0.012), 39.45 ± 8.82 and 34.57 ± 8.88 (P = 0.042), 23.04 ± 26.63 and 62.15 ± 33.82 (P = 0.002), 88.85 ± 3.13 and 83.98 ± 4.62 (P = 0.003), 157.88 ± 11.20 and 147.75 ± 13.98 (P = 0.043) respectively. TLK in L1/L2 with mild-to-moderate and severe degeneration groups was 4.59 ± 7.81 and 14.91 ± 14.75 (P = 0.026). All of L1/L2, L2/L3 and L3/L4 disc degeneration had a significant impact on SPA. SPA in L1/L2, L2/L3, and L3/L4 with mild-to-moderate and severe degeneration groups was 158.47 ± 11.97 and 147.84 ± 12.72 (P = 0.031), 159.91 ± 10.78 and 148.75 ± 13.17 (P = 0.024), 158.46 ± 10.86 and 148.61 ± 13.93 (P = 0.047) respectively. CONCLUSION: With an important impact on lumbar disc degeneration, PI, either too big or too small, may predispose to the occurrences of lumbar disc degeneration. L5/S1 disc degeneration has a significant impact on pelvis postural parameters (PT, SS). L5/S1 degeneration is a key causative factor of pelvic posterior rotation and compensatory process. L5/S1 disc degeneration has an important impact on pelvis overall parameters (SVA, SPA, C7T). And the degeneration of L5/S1 is a key cause of trunk imbalance.
