OBJECTIVE To establish the ultra-high performance liquid chromatography （UPLC） fingerprint of Jingtian granule， and to evaluate its quality by chemical pattern recognition. METHODS Luna® Omega Polar C18 column （150 mm×2.1 mm， 1.6 μm） was used as the chromatographic column， and acetonitrile-0.2% phosphoric acid solution was used as the mobile phase for gradient elution. The flow rate was 0.2 mL/min， the column temperature was 30 ℃， and the detection wavelength was 265 nm. With peak 16 as the reference peak， the UPLC fingerprint of Jingtian granule was established by the Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）. The common peaks were identified， the similarity evaluation was carried out， and the ownership of each common peak was confirmed. Hierarchical cluster analysis （HCA） and principal component analysis （PCA） in chemical pattern recognition methods were used to classify 13 batches of samples （S1- S13）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） was used to identify the key components of the differences between different batches of samples. RESULTS RSDs of precision， repeatability and stability of the UPLC method were not more than 4.4%. A total of 25 common peaks were identified in the fingerprints of 13 batches of Jingtian granules. By comparing with the reference substance fingerprint， 10 common peaks were identified， namely peak 3 （hydroxymethyl-2-furaldehyde）， peak 5 （salidroside）， peak 8（chlorogenic acid）， peak 15 （cinnamic acid）， peak 19 （aloe-emodin）， peak 20 （ammonium glycyrrhizinate）， peak 21 （rhein）， peak 23 （emodin）， peak 24 （glycyrrhetinic acid）， peak 25 （chrysophanol）. The similarities of fingerprints of 13 batches of samples were 0.955-0.996. The results of HCA showed that 13 batches of samples could be divided into three categories， among which samples S1， S5， S7， S11-S13 were clustered in one category， S4 and S6 were clustered in one category， S2， S3 and S8-S10 were clustered in one category. PCA results showed that the cumulative variance contribution rate of principal components 1-7 was 92.666%. OPLS-DA further identified 13 differential components， which were mainly derived from Polygonati Rhizoma with wine steaming， Rhodiolae Crenulatae Radix Et Rhizoma， prepared Rhei Radix Et Rhizoma and Glycyrrhizae Radix Et Rhizome Praeparata Cum Melle. CONCLUSIONS The established UPLC fingerprint of Jingtian granule is simple， stable and reproducible. Combined with the chemical pattern recognition method， it can effectively reveal the overall quality difference between different batches of Jingtian granule. The quality of Polygonati Rhizoma with wine steaming， Rhodiolae Crenulatae Radix Et Rhizoma， prepared Rhei Radix Et Rhizoma， Dioscoreae Nipponicae Rhizoma， Polyporus， Cinnamomi Ramulus， Glycyrrhizae Radix Et Rhizome Praeparata Cum Melle is the key to the overall quality of Jingtian granule.

ObjectiveTo investigate the clinical efficacy and safety of Yanling Yishou prescription combined with aerobic exercise in the intervention of heart and spleen deficiency syndrome in middle-aged white-collar workers with "stress-induced aging". MethodsA randomized， controlled， and open-label trial was conducted involving 156 patients with stress-induced aging and heart and spleen deficiency syndrome who were recruited from the Affiliated Hospital of Nanjing University of Chinese Medicine. Participants were randomly assigned via a central randomization system into an intervention group and a control group， with 78 cases in each group. The intervention group received Yanling Yishou prescription combined with a standard aerobic exercise protocol， while the control group received the standard aerobic exercise protocol only. The composition of Yanling Yishou prescription was derived from Qinggong Medical Records： 10 g Ziziphi Spinosae Semen， 10 g Codonopsis Radix， 10 g Astragali Radix， 10 g Paeoniae Radix Alba， 10 g Angelicae Sinensis Radix， 10 g Rehmanniae Radix， 10 g Atractylodis Macrocephalae Rhizoma， 10 g Poria， and 3 g Glycyrrhizae Radix et Rhizoma， decocted in water and administered 2 hours after breakfast and dinner， respectively. The aerobic exercise protocol was prescriptionted according to the 2017 guidelines of the American College of Sports Medicine， consisting of a 5-minute warm-up， a progressively increasing exercise stage （starting at 5 minutes and increasing by 1-2 minutes daily up to a maximum of 20 minutes）， and a 10-minute cool-down. Both groups were treated for 28 days and followed up for 35 days. Outcome measures included Checklist Individual Strength （CIS）， sleep quality indicators （ total sleep time， light sleep， and deep sleep）， traditional Chinese medicine （TCM） symptom scores for heart and spleen deficiency syndrome， Hospital Anxiety and Depression Scale （HADS）， physical function score from the SF-36 scale （SF-36 PF）， Pain Visual Analog Scale （Pain VAS）， and vital signs. ResultsCompared with baseline， the intervention group showed a significantly greater reduction in CIS scores and improvement in sleep quality （P<0.05， P<0.01）， while the control group showed no significant changes. Post-treatment comparisons between groups revealed that the intervention group achieved significantly better outcomes in fatigue reduction and sleep improvement （P<0.05， P<0.01）. In terms of TCM syndrome scores， the intervention group showed significant improvements in fatigue， frequent awakening， vivid dreaming， poor appetite， palpitations， and loose stools （P<0.05， P<0.01）， while the control group showed no significant improvement in poor appetite， palpitations， or loose stools. After treatment， the intervention group showed significantly better improvements in fatigue， frequent awakening， vivid dreaming， and palpitations compared to the control group （P<0.05， P<0.01）. No significant differences were observed between the two groups in SF-36 PF， HADS， and Pain VAS scores before and after treatments. No serious adverse events occurred in either group during the study period. ConclusionYanling Yishou prescription combined with aerobic exercise can alleviate symptoms such as fatigue， frequent awakening， vivid dreaming， and palpitations， improve sleep quality， and alleviate heart and spleen deficiency symptoms， thereby improving the quality of life in middle-aged white-collar workers with stress-induced aging.

Misophonia is a psychophysiological and behavioral disorder characterized by an individual's low tolerance to specific sounds， leading to intense negative emotional experiences and physiological responses. Currently， there is no standardized and universally effective treatment for misophonia in clinical practice worldwide. This article reports the case of an 18-year-old male patient with misophonia who showed poor response to sertraline combined with exposure and response prevention therapy. Subsequently， the patient received 8 weeks of Morita therapy （once a week， 50 minutes per session）， with symptomatic improvement. By presenting this case， we explore the potential efficacy of Morita therapy in treating misophonia， aiming to provide a reference for its clinical management. ［Funded by Scientific Research Development Fund Project of Shandong Second Medical University （number， 2024FYM034）］

Objective To evaluate the long-term efficacy of transjugular intrahepatic portosystemic shunt(TIPS)with bare stents and Fluency covered stents in the treatment of portal hypertension,and to discuss its clinical value.Methods The clinical data of 29 patients with intractable ascites or esophagogastric fundus varices rupture and hemorrhage caused by cirrhotic portal hypertension,who received TIPS with bare stents and covered stents at the First Affiliated Hospital of Xinjiang Medical University of China(25 patients)and the Lishui Municipal Central Hospital of China(4 patients)between August 2012 and December 2017,were retrospectively analyzed.The patients were regularly followed up to check the survival status.The postoperative cumulative shunt patency rate and cumulative survival rate of the patients were analyzed by Kaplan-Meier method.Results The technical success rate of TIPS was 100％.The mean portal vein pressure was decreased from preoperative(40.21±3.24)cmH2O to postoperative(24.55±3.55)cmH2O(P＜0.05).The patients were followed up for 5.1-10.5 years.The postoperative 1-,3-,5-,7-year primary cumulative patency rates of the shunt were 89.7％,75.9％,75.9％ and 52.5％,respectively.The postoperative 5-,7-,9-and 10-year cumulative survival rates were 100％,66.9％,66.9％ and 33.4％,respectively.The incidence of hepatic encephalopathy was 13.8％(4/29).Conclusion Using bare stents combined with Fluency covered stents for TIPS is clinically safe and effective in the treatment of portal hypertension.This technique carries higher long-term shunt patency rate and low incidence of hepatic encephalopathy.Therefore,it can be used as a substitute for Viatorr stent when necessary.(J Intervent Radiol,2024,33:295-299)

【Objective】 To monitor the effectiveness and accuracy of the blood transfusion compatibility test system by self-made weakly positive internal quality control products. 【Methods】 Red blood cells from DAT(-) healthy subjects were selected, and B/RhD(-)E(-) red blood cells were selected as tube 1. A/RhD(+ )E(+ ) was selected as tube 2 to prepare blood group quality control products according to the principle of blood group antigen compatibility, and red blood cell preservation solution and corresponding ABO blood group reagent antibody were added to make the agglutination intensity of microcolumn gel method in reverse blood typing reach a low positive value (1+ ). Tube 3 and tube 4 were prepared with five different preservation media: plasma, serum, antibody diluent, mixture of equal plasma and antibody diluent, and mixture of equal serum and antibody diluent, respectively. IgM anti-E antibody was added to tube 3, and IgG anti-D antibody was added to tube 4, so that the agglutination intensity of microcolumn gel method reached a low positive value (1+ ). 【Results】 Comparison between the 5 different preservation media showed that the preservation medium of antibody diluent was the most stable for weakly positive antibody (F=11.35, P<0.05), Agglutination intensity 1+ is assigned 5 points by AABB Technical Manual, and its score was 5.25±1.75 points. 【Conclusion】 The use of self-made weakly positive quality control products can improve the effectiveness, accuracy and sensitivity of the monitoring system, thus achieving internal quality control and ensuring the safety of clinical blood use.

Objective To determine the reference red blood cells with weak agglutination intensity of low positive quali-ty control products by comparing RhD antigen expression intensity difference according to the serological results.Methods The RhD(+)red blood cells were detected by microcolumn gel method with 1 500 times diluted anti-D typing reagent.The samples with weak and strong RhD antigen expression intensity were selected as the reference red blood cells for weak agglu-tination intensity of low positive quality control products,and verification was performed.Results Ten RhD(+)red blood cells were detected with diluted anti-D typing reagent,of which 8 were 1+and 2 were±.Red blood cells with agglutination intensity of 1+were used as the benchmark to determine the maximum dilution ratio of anti-D typing reagent when their ag-glutination intensity was 1+.As the preparation standard of low positive quality control products,the agglutination intensity of red blood cells with low RhD antigen expression intensity was extremely weak±,which was difficult to ensure the stability of its control limit properties.Based on red blood cells with agglutination intensity of±,the maximum dilution ratio of anti-D typing reagent with agglutination intensity of 1+was re-determined as the preparation standard of low positive quality con-trol products,and the results met the requirements of quality control product setting.Conclusion Using red blood cells with low RhD antigen expression intensity as the benchmark to set the weak agglutination intensity of the low positive quality control products can avoid the loss of control due to the low target value.

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.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
