The difference of chromatographic peaks among the three samples were also analyzed by HPLC methods.Results:The stems of Hedyotis diffusa Willd. were cylindrical, and the capsules were solitary or double born in the leaf axils, oblate, 2-3 mm in diameter, with a long petiole; the Hedyotis corymbosa. and Hedyotis tenelliflora. were tetragonal, and the Hedyotis corymbosa. was 2-5 capsules born in leaf axils in corymbose inflorescences, globular, 1-1.5 mm in diameter, with a slender petiole; the Hedyotis tenelliflora. were 1-3 capsules clustered in the leaf axils, ovoid with longitudinal ribs around the margin, about 1.5 mm in diameter, without the long petiole, about 1.5 mm in diameter, sessile, the edge of the leaf drying revolute long needle-like. Under the identification, the cross section of the Hedyotis diffusa Willd. stem was almost round, the middle vein of the leaves was protrusion below, the inner pericarp fiber layer consisted of two layers of fiber cells, the surface of the seed coat cells was polygon, and the wall was densely covered with small reddish brown or yellow-brown warty spots. The cross section of the Hedyotis corymbosa. stem was quadrilateral, the surface of the seed coat cell was polygon, the wall was wavy and curved, and there was no warty point on the wall. The middle veins of the Hedyotis tenelliflora. were slightly sunken in the upper part, but not protruding in the lower part; the endocarp fiber layer consisted of 8 to 13 layers of fiber cells. Moreover, the HPLC fingerprint analysis demonstrated substantial dissimilarities in the characteristic peaks of these herbs. Conclusion:The traditional and modern analysis technology show that there are some differences in the characteristics, microscopical cross section, the powder characteristics, which can effectively distinguish the Hedyotis diffusa Willd. and its two local varieties.

BACKGROUND:Inhibitory control and drug craving are the core elements of evaluating drug withdrawal in methamphetamine addicts,which has attracted much attention in academic circles.As we all know,in order to achieve complete abstinence from drug addiction,the key is to restore the damaged inhibition and control function of drug addicts and effectively reduce the craving for drugs. OBJECTIVE:To systematically analyze the relationship between exercise and methamphetamine abstinence inhibitory control and drug craving,to find out an effective exercise intervention scheme that can promote methamphetamine abstinence,and to further explore the internal mechanism of exercise,in order to provide theoretical support and applied reference for the future use of exercise in drug withdrawal. METHODS:CNKI,WanFang,VIP,Web of Science,and PubMed databases were searched for relevant literature using the keywords of"exercise,physical activity,methamphetamine,inhibitory function,craving,addiction"in Chinese and"sport*,exercise,methamphetamine,drug craving,executive function,addiction"in English.According to the inclusion and exclusion criteria,86 documents were finally included for review. RESULTS AND CONCLUSION:In terms of inhibitory control in methamphetamine abstinent individuals,either acute and long-term moderate-intensity aerobic exercise or acute high-intensity interval training can significantly improve the inhibitory control capacity of methamphetamine abstinent individuals.For long-term aerobic exercise,aerobic group exercise or full-body comprehensive exercise is more effective.If the exercise format is power cycling,it is recommended to increase the frequency of exercise intervention.In terms of the drug craving intensity in methamphetamine abstinent individuals,acute moderate-intensity aerobic exercise and resistance training,as well as long-term moderate-intensity,high-intensity,or progressive load aerobic and resistance training,can effectively reduce the drug craving in methamphetamine abstinent individuals.Exercise exerts intrinsic regulatory effects on methamphetamine-mediated addiction.Exercise can influence the expression of tyrosine hydroxylase in the brain's ventral tegmental area,thereby stimulating the expression of dopamine receptor coupling proteins and promoting dopamine synthesis in the brain's reward regions,thereby compensating for dopamine depletion caused by methamphetamine addiction.Furthermore,exercise can also regulate protein kinase A inhibitors,affecting the protein kinase A signaling pathway mediated by dopamine D1 receptors,by inhibiting protein kinase A,thus affecting cAMP response element-binding protein and regulating methamphetamine addiction.Additionally,exercise can also,at the genetic level,affect the expression of the c-fos gene in the brain's nucleus accumbens region,activate a subset of glutamatergic neurons in this area,generate a rewarding effect,and thus improve methamphetamine addiction.Although current research has confirmed the relationship between exercise and methamphetamine addiction and has clarified the brain mechanisms underlying the effects of exercise,whether there are other brain regulatory pathways for the effects of exercise remains to be explored through more scientifically rigorous animal or human experiments,starting from the cellular or molecular level.

Objective:To establish auto verification rules for the routine coagulation assays,and to provide reference for clinical laboratories to improve the quality and efficiency of results verification.Methods:A total of 24,510 specimens of sodium citrate anticoagulation routine coagulation test from the laboratory departments of eight hospitals including the First Medical Center,Chinese PLA General Hospital during January to March 2020 were collected and randomly divided into a rule establishment group and a rule verification group,with 6,670 specimens in the rule establishment group,including 2,056 Delta checks,and 17,840 specimens in the rule validation group,including 3,210 Delta checks.The activities of prothrombin time(PT),activated partial thromboplastin time(APTT),fibrinogen(Fib),thrombin time(TT),D-dimer(DD)and/or antithrombin(AT)were detected by Stago STA R Max automatic coagulation analyzer and supporting reagents.Taking the manual verification results as the standard,the auto verification and manual false negative rate(invalid verification),false positive rate(invalid interception),pass rate,positive coincidence rate,negative coincidence rate,verification consistency rate and specimen turnaround time(TAT)of the two groups were calculated.Results:The auto verification rules and the application process were preliminarily established,including internal quality control,alarm information,auto verification scope,critical value and deviation value inspection.In the rule establishment group,the single item pass rate was 82.6%-92.4%,and the overall pass rate was 73.8%.The consistency rate between auto verification and manual verification was 98.2%,and the positive coincidence rate and negative coincidence rate were 24.4%and 73.8%,respectively.In the rule verification group,the single item pass rate was 86.4%-91.5%,and the overall review pass rate was 71.5%.By simulating the application of auto verification rules,the average TAT of two hospitals among the eight hospitals was shortened by 1.5 hours and 2.1 hours,respectively.Conclusion:The application of auto verification rules can reduce workload of manual verification,and significantly shorten the TAT,and improve the report efficiency of the laboratory.

Calcium-activated chloride channels(CaCCs)are a class of channel proteins that trans-port chloride ions activated by intracellular calcium,which play a crucial role in regulating membrane potential,intracellular calcium balance,and cell excitability,particularly in neurons and muscle cells.In the Anoctamin(Ano)family,Ano1 is the most classic CaCC.Targeted modulators of Ano1 have poten-tial therapeutic effects against such diseases as cancer,cystic fibrosis,hypertension,diarrhea,and asthma.Since the discovery of Ano1 in 2008,several methods for screening CaCC-specific modulators have emerged including high-throughput primary screening of fluorescent proteins,electrophysiological patch clamp technique and virtual screening,and identification of small molecule modulators with diverse pharmacological effects.This paper summarizes the principles,advantages and disadvantages of the mainstream screening methods,and reviews the chemical structures and potential applications of Ano1-specific modulators discovered to date.

Objective:To evaluate the effect of family intervention on self-management and glycaemic control in patients with type 2 diabetes mellitus (T2DM).Methods:Clinical interventional trials on the family intervention for T2DM patients were searched in PubMed, Medline, Embase, Cochrance libraries, the CNKI, and the Wan Fang Database from January 2016 to June 2023. Literature was screened according to the inclusion and exclusion criteria. Self-management behavior, BMI and glycated haemoglobin of T2DM patients were used as outcome indicators. Meta-analysis and mapping were performed using Review Manager 5.3 software. A systematic review of the literature on indicators of self-management behavior measured using other instruments except Summary of Diabetes Self-Care Activities.Results:A total of 1 342 relevant papers were retrieved and 13 papers were included in the analysis, involving 1 454 patients, 740 in the intervention group and 714 in the control group. Meta-analysis showed that the inclusion of home-based intervention helped adult T2DM patients to improve self-management ( WMD=5.03, 95% CI:4.43-5.63, P<0.001) and reduce glycated hemoglobin compared with the hospital-patient dichotomous model ( WMD=-0.77, 95% CI:-1.32--0.21, P=0.007), but the effect on BMI was unclear ( WMD=-0.38, 95% CI:-1.04-0.28, P=0.25). The results of the systematic review supported that home-based intervention improving self-management behaviors of adult T2DM patients. Conclusion:Family intervention can improve self-management behaviors and reduce glycated haemoglobin levels in adults T2DM patients.

Objective:To explore the genes related to primary myelofibrosis (PMF) and signaling pathways as well as the possible clinical significance.Methods:A total of 3 mRNA expression datasets of PMF (GSE26049, GSE61629 and GSE53482) were downloaded from Gene Expression Omnibus (GEO) database, including the data of peripheral blood samples from 55 PMF patients and 58 controls. The differentially expressed genes (DEG) between PMF patients and the controls were identified by using online tool GEO2R. Gene ontology (GO) annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed on the common DEG of the 3 datasets, and then protein interaction (PPI) network was constructed. The key nodes of the common DEG in PPI network were calculated by using MCC method and Degree method in cytoHubba program; finally the top 10 hub genes were selected and the hub genes shared by the 2 methods were obtained. Peripheral blood samples of 25 PMF patients and 10 controls (normal hematopoietic stem cell transplant donors or iron deficiency anemia patients) admitted to the Second Hospital of Shanxi Medical University from September 2017 to June 2021 were retrospectively collected. Reverse transcription-fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of 10 screened common hub genes in each sample, and the expressions of all genes at transcriptional level of the two groups were compared.Results:A total of 239 common DEG between PMF patients and the controls were screened out in the 3 datasets, including 153 downregulated DEG and 86 upregulated DEG. The GO enrichment analysis showed that the common downregulated DEG were significantly enriched in negative regulation of transcription, translation and fibroblast proliferation, while the upregulated DEG were mainly enriched in protein ubiquitination and ubiquitin-dependent protein catabolic process. The KEGG pathway analysis indicated that the upregulated common DEG and downregulated common DEG were both enriched in PI3K/Akt signaling pathway, cancer pathways and transcriptional misregulation in cancer. There were 8 common hub genes shared by the 2 methods among the top 10 genes ranked by MCC and Degree methods, including 6 downregulated common DEG (TP53, MYC, ATM, FYN, PTPRC and ATRX) and 2 upregulated common DEG (VEGFA and FOXO3). These above 8 common hub genes were mainly involved in PI3K/Akt signaling pathway, cell cycle and cancer transcriptional regulation signaling pathways. RT-qPCR detection of clinical peripheral blood samples showed that the relative expression levels of mRNA in 6 downregulated common DEG of PMF patients were lower compared with those in controls, while the differences were not statistically significant (all P > 0.05); the relative expression levels of mRNA in 2 upregulated common DEG of PMF patients were higher compared with those in controls, and the differences were statistically significant ( U value was 33.00, 36.00, respectively; P value was 0.021, 0.033, respectively). Conclusions:Bioinformatics and clinical sample verification show that VEGFA and FOXO3 are up-regulated in PMF patients, which are mainly involved in the PI3K/Akt signaling pathway, cell cycle and cancer transcriptional regulation signaling pathway. Both genes may be related to the development of PMF and may become potential therapeutic targets.

Background/Aims: To investigate the autoantibody against fumarate hydratase (FH), which is a specific liver failure-associated antigen (LFAA) and determine whether it can be used as a biomarker to evaluate the prognosis of acute-on-chronic liver failure (ACLF). Methods: An immunoproteomic approach was applied to screen specific LFAAs related to differential prognosis of ACLF (n=60). Enzyme-linked immunosorbent assay (ELISA) technology was employed for the validation of the frequency and titer of autoantibodies against FH in ACLF patients with different prognoses (n=82). Moreover, we clarified the expression of autoantibodies against FH in patients with chronic hepatitis B (n=60) and hepatitis B virus-related liver cirrhosis (n=60). The dynamic changes in the titers of autoantibodies against FH were analyzed by sample collection at multiple time points during the clinical course of eight ACLF patients with different prognoses. Results: Ultimately, 15 LFAAs were screened and identified by the immunoproteomic approach.Based on ELISA-based verification, anti-FH/Fumarate hydratase protein autoantibody was chosen to verify its expression in ACLF patients. ACLF patients had a much higher anti-FH autoantibody frequency (76.8%) than patients with liver cirrhosis (10%, p=0.000), patients with chronic hepatitis B (6.7%, p=0.022), and normal humans (0%, p=0.000). More importantly, the frequency and titer of anti-FH protein autoantibodies in the serum of ACLF patients with a good prognosis were much higher than that of patients with a poor prognosis (83.9% vs 61.5%, p=0.019; 1.41±0.85 vs 0.94±0.56, p=0.017, respectively). The titer of anti-FH autoantibodies showed dynamic changes in the clinical course of ACLF. Conclusions The anti-FH autoantibody in serum may be a potential biomarker for predicting the prognosis of ACLF.
