Objective This study aimed to explore the potential targets of Yishenqingli Formula in treating idiopathic membranous nephropathy(IMN)using a combination of liquid chromatography-mass spectrometry(LC-MS)analysis and network pharmacology.Methods The active ingredients of the Yishen Qingli Formula were identified through the BATMAN-TCM database and LC-MS qualitative analysis.The biological processes and mechanism pathways of the Yishen Qingli Formula in treating IMN were predicted using network pharmacology,and molecular docking and in vitro,experiments were conducted to verify the selected core targets.The core targets were selected and validated through molecular docking and in vitro experiments.Results A total of 15 active ingredients were selected from the Yishen Qingli Formula,and 72 core genes were obtained by intersecting its target with the IMN disease target.GO enrichment analysis results showed that the regulation of apoptosis signaling pathway,white cell migration,peptide tyrosine phosphorylation,and so on were involved;The KEGG pathway enrichment analysis results showed that the treatment of IMN with Yishen Qingli Formula involves apoptosis-related signaling pathways such as TNF,PI3K/AKT,MAPK,etc.In vitro,experiments have shown that Yishen Qingli Formula can reduce podocyte apoptosis by regulating the PI3K/AKT pathway.Conclusion Yishen Qingli Formula is a treatment for idiopathic membranous nephropathy through multiple targets and pathways.It has an anti-apoptotic effect on the C5b-9 induced podocyte sub-lysis model,and its mechanism of action may be related to the TNF,PI3K/AKT,MAPK signaling pathways.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

This paper makes an interpretation of the collection Acupuncture: how to improve the evidence base published by BMJ & BMJ Open. Studies show that the quality of randomized controlled trial (RCT) of acupuncture is low, and multivariable Meta-regression analysis fails to confirm most factors commonly believed to influence the effect of acupuncture. The methodological challenges in design and conduct of RCT in acupuncture were analyzed, and a consensus on how to design high-quality acupuncture RCT was developed. The number of acupuncture systematic reviews was huge but the evidence was underused in clinical practice and health policy, and a large number of western clinical practice guidelines recommended acupuncture therapy, but the usefulness of recommendations needed to be improved. In view of the problems in clinical research on acupuncture mentioned in this collection, combined with the analysis of the purpose of clinical research on acupuncture, perspectives, study types, as well as the relationship between evidence and clinical decision-making, a five-stage study paradigm of clinical research on acupuncture is proposed.

Post-traumatic stress disorder (PTSD) is a reactive mental disorder that occurs after an individual was exposed to a traumatic event,and the core of the treatment is the extinction of conditioned fear memory caused by stress.Fear memory is an incentive mechanism based on external stimuli that occupy a central position in the defense system.Traditional memory concept convinced that the original memory traces were in an unstable state when the memory was activated.This process is called memory reconsolidation.The research has proved the existence of the fear memory reconsolidation,but the specific mechanism of reconsolidation has not been clarified.The animal studies show that many brain sites and molecular mechanisms are involved in the process of fear memory reconsolidation.Understanding the underlying mechanisms of fear memory reconsolidation is conducive to the treatment of specific phobias and PTSD.This review summarized the brain structure and molecular mechanism of conditioned fear memory reconsolidation,providing a new direction for the in-depth study of conditioned fear memory reconsolidation and PTSD.

OBJECTIVETo explore possible mechanism of electroacupuncture (EA) for regulating immune function in anxiety disorder (AD) rats by observing the effect of acupuncture on the histology of thymus and expressions of atrial natriuretic peptide (ANP) and natriuretic peptide receptor type A (NPR- A) in thymus.

METHODSTotally 34 SD healthy rats were randomly divided into the blank control group (n = 10), the model group (n = 12), the EA group (n = 12). Anxiety model was established in rats of the model group and the EA group by using chronic unpredictable stress (CUS) stimulation. EA (15/25 Hz) at Neiguan (PC6) and Shenmen (HT7) was performed in the EA group, with 15-min needle retaining, once every other day, 15 days in total. Needle was fixed at same acupoints for 15 min without electric stimulus in the other two groups. Anxiety-like behavior was measured by elevated plus-maze (EPM) test. Pathological changes of thymus tissue were observed by optical microscope. Expressions of ANP and NPR-A in thymus were measured by immunohistochemical assay.

RESULTSThe thymus tissue in the model group was severely atrophied, with unclear structure of thymic lobules, unclear margin of thymic medulla, loosely arranged lymphocytes ,and obviously enlarged volume of thymic corpuscle. The thymus tissue in the EA group was mildly atrophied, with existent structure of thymic lobules, clear margin of thymic medulla, densely arranged lymphocytes in cortical region, and widened medullary area. Com- pared with the blank control group, the percentage of open-arms entries (OE%) in the total QE times ob- viously decreased in the model group (P < 0.05), ANP expression obviously increased (P < 0.05), and NPR-A expression obviously decreased (P < 0.01). Compared with the model group, OE% was obviously elevated (P < 0.05), ANP expression obviously decreased (P < 0.05), and NPR-A expression obviously increased (P < 0.01) in the EA group.

CONCLUSIONEA not only could reduce anxiety of rats, but also could improve chronic stress induced thymus injury through intervening synthesis and secretion of ANP, as well as the expression of NPR-A (a specific receptor of ANP).

To treat respiratory distress syndrome, surfactant is currently delivered via less invasive surfactant administration (LISA) or INtubation SURfactant Extubation (INSURE). The aim of this study was to compare the effect of the two delivery methods of surfactant on cerebral autoregulation. Near infrared spectroscopy monitoring was carried out to detect cerebral oxygen saturation (ScO), and the mean arterial blood pressure (MABP) was simultaneously recorded. Of 44 preterm infants included, the surfactant was administrated to 22 via LISA and 22 via INSURE. The clinical characteristics, treatments and outcomes of the infants showed no significant differences between the two groups. The correlation coefficient of ScOand MABP (r) 5 min before administration was similar in the two groups. During surfactant administration, rincreased in both groups (0.44±0.10 to 0.54±0.12 in LISA, 0.45±0.11 to 0.69±0.09 in INSURE). In the first and second 5 min after instillation, rwas not significantly different from baseline in the LISA group, but increased in the first 5 min after instillation (0.59±0.13, P=0.000 compared with the baseline in the same group) and recovered in the second 5 min after instillation (0.48±0.10, P=0.321) in the INSURE group. There were significant differences in the change rates of rbetween the two groups during and after surfactant administration. Our results suggest that cerebral autoregulation may be affected transiently by surfactant administration. The effect duration of LISA is shorter than that of INSURE (<5 min in LISA vs. 5-10 min in INSURE).
