Pharmacokinetics and safety of a new generic lurasidone: a phase I bioequivalence study in healthy Chinese subjects.

Latuda® is a novel antipsychotic drug for schizophrenia and bipolar depression. A bioequivalence trial was performed to investigate the bioequivalence of Latuda® and its generic drug lurasidone. Two independent trials were carried out, each involving 28 subjects. In the fasting trial, subjects were randomly assigned to two groups (1:1 ratio), receiving either 40 mg of generic lurasidone or Latuda®. After a 7-day washout period, subjects entered the second period with a crossover administration of 40 mg of generic lurasidone or Latuda®. The postprandial study design was similar to that of the fasting study. In the fasting study, the pharmacokinetic (PK) parameter values of generic lurasidone and Latuda® were as follows: the Cmax was 28.84 ± 19.34 ng/ml and 28.22 ± 21.19 ng/ml, respectively; the AUC0-t was 121.39 ± 58.47 h*ng/ml and 118.35 ± 52.24 h*ng/ml, respectively; and the AUC0-∞ was 129.63 ± 63.26 h*ng/ml and 126.59 ± 57.99 h*ng/ml, respectively. The primary pharmacokinetic parameter, Cmax, was assessed for equivalence using reference-scaled average bioequivalence (RSABE), while other parameters (AUC0-t, AUC0-∞) were evaluated using average bioequivalence (ABE). The results indicate that both Cmax and AUC meet the equivalence criteria. In the postprandial study, the PK values of generic lurasidone and Latuda® were as follows: the Cmax was 74.89 ± 32.06 ng/ml and 83.51 ± 33.52 ng/ml, respectively; the AUC0-t was 274.77 ± 103.05 h*ng/ml and 289.26 ± 95.25 h*ng/ml, respectively; and the AUC0-∞ was 302.44 ± 121.60 h*ng/ml and 316.32 ± 109.04 h*ng/ml, respectively. The primary pharmacokinetic parameters (Cmax, AUC0-t, AUC0-∞) were assessed for equivalence using ABE, and both met the equivalence criteria. In the study, lurasidone and Latuda® both exhibited acceptable safety and tolerability. The results displayed that lurasidone and Latuda® were bioequivalent and safe in healthy Chinese participants. Clinical Trial Registry: This trial is registered at chinadrugtrials.org.cn (no.: CTR20191717, date: 2019.08.29).

Chinese patent medicine as a complementary and alternative therapy for type 2 diabetes mellitus: A scoping review.

OBJECTIVE: This scoping review aims to document Chinese Patent Medicines (CPMs) for Type 2 Diabetes Mellitus, explore whether CPMs can improve patients' health outcomes, and set priorities in addressing research gaps in this area. METHODS: Following the framework of PRISMA-SCr, we proposed the research questions based on PICOS principle, and searched the CPMs for T2DM from three drug lists, followed by a systematic search of the literature in eight databases from their inception to June 22, 2023. Then, we developed the eligibility criteria and systematically reviewed the relevant studies, retained the studies about CPMs for T2DM, extracted the related data, and identified the differences across studies in structured charts. RESULTS: A total of 25 types of CPMs were extracted from the three drug lists. Radix astragali appeared most frequently (19 times) among the herbal medicinal ingredients of CPMs. A total of 449 articles were included in the full-paper analysis ultimately, all of which were about 20 types of CPMs, and there were no related reports on the remaining five CPMs. Except about a quarter (25.39 %, 114/449) using CPMs alone, the remaining studies all involved the combination with oral hypoglycemics for T2DM. Biguanides are the most common drugs used in combination with CPMs (50.14 %, 168/335). Fasting plasma glucose (FPG) is the most frequently reported outcomes in efficacy evaluation (82.41 %, 370/449). CONCLUSION: There are a total of 25 types of CPMs currently available for T2DM patients. However, the volume of related evidence on these CPMs varies. It is necessary to standardize the combined use of CPMs and conventional medicine and select appropriate outcomes in future studies.

Analysis of influencing factors on long COVID in COVID-19 patients infected with omicron variant three months after discharge: a cross-sectional study.

BACKGROUND: The purpose of this study is to analyze the influencing factors associated with Long-COVID in patients infected with Omicron variant of COVID-19 in Changchun City, Jilin Province, China three months after discharge in March 2022. METHODS: In this study, we conducted a telephone follow-up based on the real-world data collected from the Affiliated Hospital to Changchun University of Chinese Medicine, Changchun Tongyuan Shelter Hospital and Changchun Infectious Disease Hospital during the COVID-19 epidemic in Changchun in March 2022. We used the Global COVID-19 Clinical Platform Case Report Form for Post COVID condition as a follow-up questionnaire to collect the general information, past medical history, clinical symptoms, COVID-19 vaccine inoculation doses, and other relevant information to analyze the symptom characteristics of COVID-19 patients three months after discharge from the hospital and related factors affecting Long COVID. RESULTS: A total of 1,806 patients with COVID-19 were included in this study, 977 males and 829 females, with a mean age of 38.5 [30.0, 49.4] years, and the number of female patients suffering from Long COVID (50.87%) was greater than male patients (p = 0.023). The binary logistic regression analysis of factors influencing Long COVID showed that smoking history (OR (95%CI) = 0.551(0.425-0.714), p < 0.001, taking never smoking as a reference), allergy history (OR (95%CI) = 1.618 (1.086-2.413), p-value 0.018, taking no allergy as a reference), first symptoms (OR (95%CI) = 0.636 (0.501-0.807), p < 0.001, with no first symptoms as reference) and COVID-19 vaccine inoculation doses (OR (95%CI) = 1.517 (1.190-1.933), p-value 0.001, with ≤ 2 doses of COVID-19 vaccine inoculation doses as reference) constituted its influencing factors. The first symptoms of patients on admission mainly included fever (512 cases, 71.81%), cough (279 cases, 39.13%) and dry or itchy throat (211 cases, 29.59%). The most common symptoms of Long COVID were persistent fatigue (68 cases), amnesia (61 cases), insomnia (50 cases) and excessive sweating (50 cases). CONCLUSION: The first symptoms on admission were predominantly fever, cough and dry or itchy throat. The most common symptoms of Long COVID were persistent fatigue, amnesia, insomnia and excessive sweating, and female patients were at a higher risk of Long COVID.

Efficacy of cutting balloon angioplasty versus high-pressure balloon angioplasty for the treatment of arteriovenous fistula stenoses in patients undergoing hemodialysis: Systematic review and meta-analysis.

This systematic review and meta-analysis aimed to assess and compare the therapeutic outcomes of cutting balloon angioplasty and high-pressure balloon angioplasty for arteriovenous fistula stenosis in hemodialysis patients. All studies indexed in PubMed, Embase, and Cochrane Library Web of Science were retrieved. The retrieval deadline was July 15, 2023. Risk of bias 2.0 was used to evaluate the quality of the included studies. Revman 5.4 software was used for data analysis. This review included three studies and 180 patients, with 90 patients in the cutting balloon angioplasty group and 90 patients in the high-pressure balloon angioplasty group. The results of the meta-analysis suggested that compared with high-pressure balloon angioplasty, cutting balloon angioplasty can improve primary lesion patency rates of internal arteriovenous fistulas at 6 months (relative risk, 1.45; 95% confidence interval, 1.08-1.96; P = 0.01). However, there were no significant differences between the technical success rate (relative risk, 0.99; 95% confidence interval, 0.93-1.05; P = 0.72) and clinical success rate (relative risk, 1.01; 95% confidence interval, 0.95-1.07; P = 0.73). Therefore, cutting balloon angioplasty is likely to increase primary lesion patency rates at 6 months. However, more high-quality, large-sample, multicenter, randomized controlled trials are needed for further validation due to the limited number of included studies.

A bibliometric review of Glycyrrhizae Radix et Rhizoma (licorice) research: Insights and future directions.

ETHNOPHARMACOLOGICAL RELEVANCE: Glycyrrhizae Radix et Rhizoma, a Chinese herb known as licorice, is frequently incorporated in traditional Chinese medicine (TCM) formulations, due to its significant medicinal value and sweet taste. Despite licorice's merits, no systematic scientometric study has yet been conducted to analyze licorice research trends over the past 25 years. AIM OF THE STUDY: We conducted this study with the aim to provide researchers with a comprehensive overview of research advances in the application of licorice as a TCM ingredient and to offer valuable insights to guide future endeavors in this research field. METHODS: We selected licorice-related research papers published between 1997 and 2021 from the Web of Science Core Collection then conducted a scientometric analysis using VOSviewer and CiteSpace software tools. RESULTS: A total of 4883 licorice-related publications, including 4511 research papers, 372 review papers, and their cited references, were included in the analysis. Most of these articles were authored by researchers in China (36.8%), including major contributors Wang Ying, Ye Min, and Zhang Yu. The Journal of Ethnopharmacology (impact factor = 5.4) hosted the greatest number of papers (145 articles). Keyword cluster analysis revealed three keyword categories indicating that current licorice research is focused on licorice quality control and identification of licorice active ingredients and associated pharmacological mechanisms. CONCLUSION: This study provides a comprehensive overview of licorice-related research trends over the past 25 years as based on quantitative and qualitative analyses of published licorice-related articles. The results of this multi-level analysis of licorice research related to TCM formulations, chemical compositions, and pharmacological effects should provide valuable reference data and insights to guide future research endeavors in this field.

Weak-value amplified surface plasmon resonance sensor based on joint detection of optical activity and refractive index.

A versatile system combining surface plasmon resonance (SPR) and weak value amplification (WVA) is presented, which can measure the optical activity and refractive index of chiral/achiral molecules, ionic compounds, and their mixture in solution individually or simultaneously. The variations in output light intensity directly exhibit high sensitivity to changes in optical activity and refractive index of the aforementioned substances. Furthermore, by examining the correlation between the intensity variation trend and the optical activity of the chiral molecule, the molecule's absolute configuration can be ascertained. Utilizing this instrument, optical rotation with a resolution of 3.04 × 10-6 rad and refractive index with a resolution of 5.57 × 10-9 RIU were obtained. As an attempt at practical application, this sensor was used to detect the adulteration of glucose and fructose in pure honey. Not only can such compromised honey be distinguished from pure honey using the refractive index or optical rotation, but the difference in optical activity can also be employed to effectively differentiate between adulterated honey samples containing glucose and fructose separately.

Efficacy and safety of yoga for the management of chronic low back pain: an overview of systematic reviews.

Background: Yoga is a non-pharmacological conservative therapeutic modality that can be employed for the management of chronic low back pain (CLBP). In this overview, we have summarized and evaluated data from current systematic reviews (SRs) on the use of yoga for CLBP. Methods: We comprehensively searched SRs on the use of yoga for CLBP in nine electronic databases from inception to September 2023. The methodological quality was evaluated using the Assessment of Multiple Systematic Review Scale-2 (AMSTAR-2). The reporting quality of the included SRs was evaluated using the Preferred Reporting Item for Systematic Review and Meta-Analysis-2020 (PRISMA-2020), and the quality of data was graded using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Two independent researchers performed the screening, data extraction, and quality assessment process of SRs. Results: A total of 13 SRs were included. The results of the AMSTAR-2 indicated that the methodological quality of the included studies was relatively low. The PRISMA-2020 checklist evaluation results indicated that methodological limitations in reporting, especially regarding data processing and presentation, were the main weaknesses. The GRADE assessment indicated that 30 outcomes were rated moderate, 42 were rated low level, and 20 were rated very low level. Downgrading factors were mainly due to the limitations of the included studies. Conclusion: Yoga appears to be an effective and safe non-pharmacological therapeutic modality for the Management of CLBP. Currently, it may exhibit better efficacy in improving pain and functional disability associated with CLBP. However, the methodological quality and quality of evidence for SRs/MAs in the included studies were generally low, and these results should be interpreted cautiously.

Intelligent water perimeter security event recognition based on NAM-MAE and distributed optic fiber acoustic sensing system.

Distributed optical acoustic sensing (DAS) based on phase-sensitive optical time-domain reflectometry can realize the distributed monitoring of multi-point disturbances along an optical fiber, thus making it suitable for water perimeter security applications. However, owing to the complex environment and the production of various noises by the system, continuous and effective recognition of disturbance signals becomes difficult. In this study, we propose a Noise Adaptive Mask-Masked Autoencoders (NAM-MAE) algorithm based on the novel mask mode of a Masked Autoencoders (MAE) and applies it to the intelligent event recognition in DAS. In this method, fewer but more accurate features are fed into the deep learning model for recognition by directly shielding the noise. Taking the fading noise generated by the system as an example, data on water perimeter security events collected in DAS underwater acoustic experiments are used. The NAM-MAE is compared with other models. The results indicate higher training accuracy and higher convergence speed of NAM-MAE than other models. Further, the final test accuracy reaches 96.6134%. It can be demonstrated that the proposed method has feasibility and superiority.

Organelle Imaging with Terahertz Scattering-Type Scanning Near-Field Microscope.

Organelles play core roles in living beings, especially in internal cellular actions, but the hidden information inside the cell is difficult to extract in a label-free manner. In recent years, terahertz (THz) imaging has attracted much attention because of its penetration depth in nonpolar and non-metallic materials and label-free, non-invasive and non-ionizing ability to obtain the interior information of bio-samples. However, the low spatial resolution of traditional far-field THz imaging systems and the weak dielectric contrast of biological samples hinder the application of this technology in the biological field. In this paper, we used an advanced THz scattering near-field imaging method for detecting chloroplasts on gold substrate with nano-flatness combined with an image processing method to remove the background noise and successfully obtained the subcellular-grade internal reticular structure from an Arabidopsis chloroplast THz image. In contrast, little inner information could be observed in the tea chloroplast in similar THz images. Further, transmission electron microscopy (TEM) and mass spectroscopy (MS) were also used to detect structural and chemical differences inside the chloroplasts of Arabidopsis and tea plants. The preliminary results suggested that the interspecific different THz information is related to the internal spatial structures of chloroplasts and metabolite differences among species. Therefore, this method could open a new way to study the structure of individual organelles.

Label-free detection and identification of single bacteria via terahertz near-field imaging.

In recent years, terahertz (THz) imaging has attracted much attention because of its ability to obtain physical and chemical information in a label-free, noninvasive and nonionizing manner. However, the low spatial resolution of traditional THz imaging systems and the weak dielectric response of biological samples hinder the application of this technology in the biomedical field. In this paper, we report a new THz near-field imaging method for a single bacteria, through the coupling effect of nanoscale radius of probe and platinum gold substrate, which greatly enhances THz near-field signal of biological samples. A THz super-resolution image of bacteria has been successfully obtained by strictly controlling the relevant test parameters such as tip parameters and driving amplitude. By analyzing and processing the THz spectral image, the morphology and inner structure of bacteria have been observed. The method has been used to detect and identify Escherichia coli represented by Gram-negative bacteria and Staphylococcus aureus represented by Gram-positive bacteria. This application provides a new label-free, noninvasive and nonionizing testing protocol for the detection of single bacteria.

Effects of Qishen Dihuang Granules on Intestinal Microbiota in Experimental Autoimmune Myasthenia Gravis Model Rats.

Objective: Effects of Qishen Dihuang (QSDH) granules on intestinal flora of an experimental autoimmune myasthenia gravis (EAMG) model rat were investigated (CNBI:PRJNA910532). Methods: Thirty-six female Lewis rats were assigned to Control, EAMG, QSDH-low-dose, QSDH-medium-dose, QSDH-high-dose, and Prednisone groups using the random number table method (6 rats/group). A rat EAMG model was established by injecting Rα97-116 peptide antigen. Each day for 30 days, gavages were administered to rats in the Chinese medicine group (QSDH granules in different concentrations), Prednisone group (prednisone), and Control and Model groups (0.5% CMC). After 30-day gavages, rat fecal samples were collected and the microbial community composition and diversity differences between intestinal microbiota of EAMG and QSDH granule-treated groups were analyzed using 16S amplicon sequencing to explore the effect underlying QSDH granules alleviation of EAMG. Results: The clinical symptoms of rats in each treatment group improved significantly after the intervention treatment with QSDH granules. Comparison of the relative abundance of microorganisms in the gut flora of different groups with that of the EAMG group rats revealed: significantly lower phylum-level Bacteroidetes abundance and significantly greater Actinobacteria abundance in the QSDH-high-dose group and a significantly greater Firmicutes/Bacteroidetes ratio in the QSDH-medium-dose group; significantly increased family-level QSDH-high-dose group abundances of Lachnospiraceae and Trichospiraceae (Firmicutes), significantly increased QSDH-medium-dose group Lactobacillaceae abundance, and significantly increased QSDH-low-dose group Bacteroidaceae abundance; genus-level, QSDH-high-dose group Prevotella and Coprococcus abundances were significantly increased and Turicibacter and Lactobacillus abundances were significantly decreased, while QSDH-medium-dose group Akkermansia and Lactobacillus abundances were significantly increased. Greater overall community richness, diversity, and genetic diversity were observed in QSDH granules-treated groups, but differences were insignificant (P > .05). The most significant inter-group genus-level community marker differences involved Prevotella, Ruminococcus, Coprococcus, and Turicibacter. Conclusion: QSDH granules may regulate EAMG rat intestinal flora by decreasing relative abundances of Turicibacter and Clostridium and increasing relative abundances of Bifidobacterium, Lachnospiraceae, and Prevotella.

Comparing the bioequivalence and safety of liraglutide in healthy Chinese subjects: an open, single-dose, randomized, repeated, two-sequence, two-cycle phase I clinical trial.

BACKGROUND: Glucagon-like peptide-1 (GLP-1) is an endogenous incretin hormone. Liraglutide, a GLP-1 receptor agonist, can lower blood sugar by increasing insulin production and inhibiting the production of glucagon. This study researched the bioequivalence and safety of the test and reference drugs in healthy Chinese subjects. RESEARCH DESIGN AND METHODS: Subjects (N = 28) were randomly divided into group A and group B at a ratio of 1:1 for a two-cycle cross-over study. There was single dose per cycle with subcutaneous injection of the test and reference drugs, respectively. The washout was set at 14 days. Plasma drug concentrations were detected by specific liquid chromatography and tandem mass spectrometry (LC-MS/MS) assays. Statistical analysis of major pharmacokinetic (PK) parameters was conducted to assess drug bioequivalence. In addition, we evaluated the safety of the drugs throughout the trial. RESULTS: The geometric mean ratios (GMRs) of Cmax, AUC0-t, and AUC0-∞ for the test and reference drugs were 107.11%, 106.56%, 106.09%, respectively. The 90% confidence intervals (CIs) were all within 80%-125%, meeting the bioequivalence standards. In addition, both had good safety in this study. CONCLUSION: The study shows that the two drugs had similar bioequivalence and safety. CLINICAL TRIAL REGISTRATION: DCTR: CTR20190914; ClinicalTrials.gov: NCT05029076.

Reporting Quality of Oral TCM Systematic Reviews Based on the PRISMA Harms Checklist from 2013 to 2020.

Background: Systematic reviews focusing on the effectiveness of different kinds of healthcare interventions have been widely published, but there were few guidelines for reporting safety concerns before 2016. The PRISMA harms checklist, which was published in 2016, can standardize reporting quality. Objectives: To evaluate the safety information reporting quality of oral traditional Chinese medicine (TCM) in systematic reviews before and after the PRISMA harms checklist was published and to explore factors associated with better reporting. Methods: We searched PubMed, the Cochrane Library, and Embase to identify all systematic reviews using oral TCM as interventions published before (from 2013 to 2015) and after (from 2017 to 2020) the PRISMA harms checklist was published. We used the PRISMA harms checklist to assess the quality of reporting of the safety information to included systematic reviews. Results: In total, 200 systematic reviews were sampled from eligible studies published between 2013 and 2020. Reviews from 2016 were excluded. Scores on the PRISMA harms checklist (23 items) ranged from 0 to 12. A systematic reviews published after 2016 had better reporting quality compared with studies published before 2016 with regard to the title (P=0.03), results of individual studies (P=0.016), and risk of bias across studies (P=0.043). In all included systematic reviews of our study, the state conclusion in coherence with review findings was reported adequately with the proportion of adherence at 95%; other items had a reporting proportion ranging from 0% to 57%. The four essential reporting items of the PRISMA harms checklist also had a low reporting quality ranging from 0% to 4%. Conclusions: Oral TCM systematic reviews reported inadequate safety information before and after the PRISMA harms checklist was published. This survey suggested that the PRISMA harms checklist should be recommended more to both original research and systematic review authors.

Pharmacokinetics and bioequivalence of two pomalidomide capsules in healthy chinese subjects under fasting and fed conditions.

OBJECTIVE: Imnovid® is an immunomodulatory drug with antineoplastic activity. The aim of this study was to evaluate the bioequivalence and safety of the generic drug pomalidomide (Chia Tai Tianqing Pharmaceutical Group Co., Ltd) and its originator product Imnovid® (Celgene Europe Ltd) in the fasting and fed states, respectively. METHODS: The research consisted of two parts: one with a dose of 1 mg and the other with a dose of 4 mg. 48 healthy subjects were included in each study and were divided into two groups (fasting group and fed group) at a 1:1 ratio to administrate study drugs orally. The plasma drug concentrations were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: The 90% CI of GMR for main pharmacokinetic (PK) parameters (Cmax, AUC0 - t and AUC0-∞) met the requirements of bioequivalence standards. The incidence and severity of AEs associated with pomalidomide and Imnovid® were similar. CONCLUSION: The results proved the PK parameters of pomalidomide and Imnovid® were similar and bioequivalent. Both drugs showed safety profile well.

The effects of Ophiocordyceps sinensis combined with ACEI/ARB on diabetic kidney disease: A systematic review and meta-analysis.

BACKGROUND: Ophiocordyceps sinensis (OS), a medicinal fungus, has been made into OS preparations, which are frequently used as adjunctive therapy for patients with Diabetic Kidney Disease (DKD) in China. It is necessary to assess the efficacy and safety of OS preparations in the adjunctive treatment of DKD by conducting a systematic review and meta-analysis. OBJECTIVE: Ophiocordyceps sinensis preparations were evaluated for their efficacy and safety as adjunctive therapy to conventional drugs (angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs)) for DKD. METHODS: We searched seven electronic literature databases for randomized controlled trials (RCTs) comparing ACEI/ARB and OS combined with ACEI/ARB from inception up to March 2022. Two reviewers extracted data and assessed the risk of bias independently. Evidence certainty was rated using the GRADE system. Standardized mean difference (SMD) or mean difference (MD) was pooled with random effects models and was reported with corresponding 95% confidence intervals (CIs). Meta-analysis, sensitivity analysis and Egger's test were performed using R software (version 14.2) (PROSPERO registration no. CRD42021248634). RESULTS: Thirty eight RCTs involving 3167 patients met the inclusion criteria. No trials were reported with outcomes about kidney disease progression and cardiovascular events. In meta-analysis, compared with the control group of ACEI/ARB alone, OS combined with ACEI/ARB can achieve better effects in the treatment of DKD on reducing serum creatinine (Scr) [MDScr =-11.48 95% CI [-15.78, -7.18], p < 0.01], blood urea nitrogen (BUN) [MDBUN= -1.00, 95% CI [-1.44, -0.55], p < 0.01], ß2-microglobulin (ß2-MG) [SMDß2-MG= -1.32, 95% CI [-2.27, -0.37], p < 0.01], cystatin C (CysC) [MDCysC=-0.64, 95% CI [-0.83, -0.45], p < 0.01], 24-h urine proteinuria (24hUP) [SMD24hUP= -1.99, 95% CI [-2.68; -1.31], p < 0.01], urine microalbumin (UALB) [MDUALB= -37.41, 95% CI [-44.76, -30.06], p < 0.01] and decreasing urinary albumin excretion rate (UAER) [MDUAER= -24.11, 95% CI [-30.54, -17.68], p < 0.01] and albumin creatinine ratio (ACR) [SMDACR = 1.01, 95% CI [-1.73, -0.29], p < 0.01]. The OS adjuvant treatment also improved outcomes of blood pressure, blood glucose, blood lipid, inflammation and oxidative stress. No significant change in fasting blood glucose (FPG), glycated hemoglobin (HbA1c), malondialdehyde (MDA), and transforming growth factor beta 1 (TGF-ß1) was detected. Yet, no significant difference was found about the adverse events between the two groups. CONCLUSIONS: Ophiocordyceps sinensis preparation combined with ACEI/ARB has beneficial influence on renal function, decrease proteinuria, dyslipidemia, and even oxidative stress and inflammation in DKD patients. However, there is no trial that evaluated outcomes of kidney disease progression and cardiovascular events. Future study should move beyond surrogate endpoints to actual cardiovascular or renal outcome benefits with an aim to explore effects of OS preparation in the long-term.

[Academic characteristics of contemporary famous traditional Chinese medicine experts and schools in treatment of chronic renal failure based on SrTO].

According to the systematic review of text and opinion(SrTO) developed by the Joanna Briggs Institute(JBI), this study integrated the evidence of the medical cases, papers, medical experience, and other related research of famous experts and schools on the treatment of chronic renal failure in the field of traditional Chinese medicine(TCM) nephropathy, analyzed the academic characteristics and influencing factors from the aspects of the principle, method, recipe, and medicines, and explored the internal logic and law of inheritance and innovation in TCM nephropathy. A total of 36 famous TCM experts and 4 schools were included. The work areas are concentrated in North and South China. 94.0% of the famous TCM experts have experienced master-disciple teaching. 27.8% have studied TCM through family succession. 38.9% have been taught by multiple famous teachers. And 5.6% have not experienced master-disciple teaching. In terms of principle, method, recipe, and medicines, many innovations have been made, with 30.6% of famous TCM experts proposing new theories, 11.1% advocating staged treatment of chronic renal failure, and 47.2% summarizing the treatment methods. The formation of the academic thoughts of contemporary famous TCM experts and schools on the treatment of chronic renal failure is closely related to the learning mode, era, and work area. Contemporary famous TCM experts and schools have the academic characteristics of combining classical and clinical theories and paying more attention to TCM with western medicine supplemented. The field of TCM nephropathy has the characteristics of simultaneous inheritance and innovation. On the basis of inheriting the classical theories of TCM, it absorbs modern medical theories, combines clinical diagnosis with the syndrome and treatment law of contemporary diseases, and makes innovations in principle, method, recipe, and medicines, which has significant clinical efficacy in the treatment of chronic renal failure.

Comparative the efficacy and acceptability of immunosuppressive agents for myasthenia gravis: A protocol for systematic review and network meta-analysis.

BACKGROUND: Immunosuppressive drugs are routinely used to treat myasthenia gravis (MG). However, current recommendations provide limited evidence to support treatment options, leading to considerable variation in practice among healthcare specialists. Hence, we present a protocol for a systematic review and network meta-analysis (NMA) to update the evidence by comparing the efficacy and acceptability of oral immunosuppressive drugs for the treatment of MG. METHODS: We will conduct a systematic review and NMA of all randomized controlled trials evaluating the following oral immunosuppressive drugs for the treatment of MG. Published studies will be searched using the following databases from inception to November 23, 2021: CENTRAL, the CINAHL, MEDLINE, Embase, PsycINFO, Web of Science, and 3 Chinese databases (Chinese Biomedical Literatures Database, CNKI, and Wan Fang database). Assessment of study eligibility and data extraction will be conducted independently by 2 reviewers. The main outcome will be a quantitative MG scoring system. We will conduct Bayesian NMA to synthesize all evidence for each outcome and obtain a comprehensive ranking of all treatments. The quality of the evidence will be evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations framework. RESULTS: The objective of this study was to assess the relative clinical efficacy and acceptability of first-line immunosuppressants for the treatment of MG, using a systematic review and NMA approach. CONCLUSION: In the absence of head-to-head trials comparing therapies, evidence from this NMA of available clinical trials will inform clinicians, patients, and families the risk-benefit profiles of different treatment options.

Weight gain promotes the progression of IgA nephropathy in Asians: A protocol for systematic review and meta-analysis.

INTRODUCTION: The relationship between weight gain and progression of IgA nephropathy (IgAN) has been investigated by many researchers but remains controversial. The incidence of IgAN is significantly higher in Asia than in other regions. Therefore, we investigated the relationship between weight gain and primary IgAN in the Asian population. METHODS AND ANALYSIS: Seven databases were retrieved up to now. We stratified the included population by body mass index (BMI) and performed a meta-analysis of associated risk factors. OBJECTIVES: In this study, Asian IgAN patients with different BMI were grouped together to clarify the relationship between BMI and IgAN progression in Asian populations, so as to provide more ideas and treatment means for the prevention and treatment of IgAN in the future.

Pretreatment to terahertz absorption curves by narrow undulation constraint and Its quick implementation suggested by convex hull.

In this work, a method of pretreating THz absorption curve is proposed, which leads to minimal range in absorption, reserving necessary undulation of curve for identification by convolutional neural network. The kernel thought of proposed method is about confining the undulation of curve with a pair of narrow parallel lines and solving their optimal position by consecutively rotation of normalized curve at two fixed points. A fast algorithm is further proposed based on features of convex hull, whose procedure is described in detail. The algorithm involves definition of some important point sets, calculating and comparing slopes and determining best choice out of 4 potential rotations. The rationality of searching critical point is illustrated in a geometric way. Additionally, the adaption of the method is discussed and real examples are given to show the capacity of method to extract nonlinear information of a curve. The study suggests that methods regarding computer graphics also contributes to feature extraction with respect to THz curve and pattern recognition.
