OBJECTIVE To comprehensively evaluate the quality of adverse drug reaction （ADR） reports in clinical departments or ward （hereinafter referred to as “department”） based on game theory combinatorial weighting-technique for order preference by similarity to ideal solution （TOPSIS）-rank-sum ratio （RSR） method， providing a reference for the further standardization of ADR reporting. METHODS Based on relevant documents and scoring criteria， the ADR report quality evaluation standards previously developed by our team were modified. Using game theory principles， the fusion of subjective and objective weights for each indicator was determined. A game theory combinatorial weighting-TOPSIS-RSR model was developed to evaluate and categorize the quality of raw ADR reports submitted by departments to the pharmacy department at Bozhou Hospital of Anhui Medical University. RESULTS A total of 222 ADR reports from 23 departments were included. The game theory combinatorial weighting method identifies weak points in management， such as ADR symptoms and signs， the description of underlying diseases， timing of ADR， by optimizing the weightings of the indicators. The TOPSIS-RSR method calculates that the mean relative closeness of the departments was 0.401 7， indicating that the overall report quality ranged from moderate to substandard. 20095） Three departments， including neurosurgery， demonstrated medium reporting quality [estinate closeness （Ĉ）i ≥0.506]， while two departments， such as the respiratory department，were rated as unqualified （Ĉi＜0.278）. The remaining departments were all deemed qualified （0.278≤ Ĉi＜0.506）. CONCLUSIONS The developed game theory combinatorial weighting-TOPSIS-RSR method provides an effective approach for the quality evaluation of ADR reports， which not only balances subjective and objective weights but also facilitates comparisons among different departments. There is still room for improvement in the ADR report quality at the hospital.

OBJECTIVE To analyze the dynamic changes of inhalant allergen sensitization profiles in patients with allergic rhinitis,asthma and allergic rhinitis combined with asthma in the Beijing area.METHODS A retrospective study was conducted on patients with allergic rhinitis,asthma,and allergic rhinitis combined with asthma who visited the Allergy Department of Beijing Shijitan Hospital from January 2021 to December 2024.All patients underwent skin prick tests for 27 inhalant allergens.RESULTS A total of 28 454 patients were included.The overall positive rate of SPT was 74.21%,with the highest positive rate in the 10-14 age group(84.09%).Spring pollen and summer-autumn pollen were the main allergens,with higher positive rates than dust mites and molds(P<0.05).Juniperus chinensis was the main sensitization in patients with allergic rhinitis,while in patients with allergic rhinitis combined with asthma,sensitization to weeds such as Chenopodium album,Humulus scandens,and Artemisia sieversiana were more common.In recent years,the positive rates of sensitization to spring pollen,summer-autumn pollen,and molds all showed an upward trend(P<0.05),with the most significant increase in molds.CONCLUSION In the Beijing area,pollen,dust mites and mold are the main allergens in spring and autumn.In recent years,the sensitization rates of Juniperus chinensis and Artemisia sieversiana pollen have decreased,but the positive rate of mold sensitization has been on the rise,which still needs to be taken seriously.

Objective:To establish a quality control method for Aiye standard decoction.Methods:The ultra performance liquid chromatogrphy (UPLC) column Waters ACQUITY HSS T3 C18 (2.1 mm×150 mm,1.8 μm) was used to gradient elution by acetonitrile and 0.1% formic acid in water. 16 batches of Aiye standard decoction fingerprints were established by UPLC and the common peaks were determined in the fingerprints. The contents of 12 components were determined. The 16 batches of Aiye standard decoction were analyzed by similarity calculation, hierarchical cluster analysis (HCA), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) for analysis of differential components of Artemisiae Argyi Folium from different origins.Results:A total of 13 common peaks were marked in the fingerprints of 16 batches of Aiye standard decoction, 12 of which were identified by comparison with reference substance, including chlorogenic acid, sochlorogenic acid A, neochlorogenic acid, cryptochlorogenic acid, caffeic acid,1,3-O-Dicaffeoylquinic acid, schaftoside, isochlorogenic acid B,1,5-O-Dicaffeoylquinic acid, isochlorogenic acid C, jaceosidin and eupatilin. Similarity evaluation, PCA and HCA all classified the 16 batches of Aiye standard decoction into 2 categories. Orthogonal partial least squares discriminant analysis screened 5 differential biomarkers from 13 common peaks. The content determination results showed that the phenolic compounds and flavonoids in samples from Hubei were significantly higher than that in samples from other areas.Conclusion:This method can effectively analyze the differences in the quality of Aiye standard decoction from different origins, and provide reference for the formulation of quality standards for Aiye standard decoction and related preparations.

It was confirmed that the peak 3 was L-tryptophan, the peak 11 was tubeimoside B, the peak 12 was tubeimoside C, and the peak 13 was tubeimoside A. 15 batches of Bolbostemmatis Rhizoma standard decoction from different origins were divided into 3 categories by HCA and PCA. There was no significant difference between QAMS and the external standard method (ESM) through the system suitability inspection. Conclusion:This method is accurate, reliable and has good specificity, which can effectively evaluate the quality of Bolbostemmatis Rhizoma standard decoction.

BACKGROUND:Distal tibial tuberosity-high tibial osteotomy is a surgical treatment for knee osteoarthritis,but there is still a lack of clinical studies on its effect on ankle joints. OBJECTIVE:To observe the effects of distal tibial tuberosity-high tibial osteotomy on ankle angle on coronal plane of the radiography of the full length of lower limb in weight loading. METHODS:Data of 40 patients(41 knees)with distal tibial tuberosity-high tibial osteotomy from March 2021 to March 2022 were retrospectively analyzed,including 31 females and 9 males,20 left knees and 21 right knees,aged 49-75 years,mean(63.44±6.57)years.The radiographic data of the full length of the lower limb in weight loading were collected before,week 2 and week 48 postoperatively.Hip-knee-ankle angle,talar tilt angle,tilt angle of the ankle,tibiocrural angle,and tibial articular surface angle were measured before and after surgery. RESULTS AND CONCLUSION:(1)Hip-knee-ankle angle improved from(-6.24±3.69)° before operation to(2.59±3.49)° week 2 postoperatively and(2.15±3.49)° week 48 postoperatively.The tilt angle of the ankle changed from(-7.90±3.11)° before operation to(-2.51±2.59)° week 2 postoperatively and(-2.46±2.42)° week 48 postoperatively,with statistically significant difference(P<0.001).(2)There was no significant difference in talar tilt angle,tibiocrural angle,and tibial articular surface angle before and week 2 postoperatively.(3)No significant difference in the angle changes was detected between week 2 and week 48 postoperatively.(4)It is indicated that distal tibial tuberosity-high tibial osteotomy can not only correct genu varus but also improve ankle angle.This result remains stable after 48 weeks of weight-bearing activities.

With rapid development and maturity of single-cell measurements,single-cell biology and pathology has become an emerging discipline to understand the disease.However,it is important to address concerns raised by clinicians as to how to apply single-cell measurements for clinical practice,translate the signals of single-cell systems biology into determination of clinical phenotype,and predict patient response to therapies.This paper proposes a new system coined as the clinical artificial intelligent single-cell(caiSC)with the dynamic generator of clinical single-cell informatics,artificial intelligent analyzers,molecular multimodal reference boxes,clinical inputs and outputs,and AI-based computerization.This system provides reliable and rapid information for impacting clinical diagnoses,monitoring,and prediction of the disease at the single-cell level.The caiSC represents an important step and milestone to translate the single-cell measurement into clinical application,assist clinicians'decision-making,and improve the quality of medical services.There is increasing evidence to support the possibility of the caiSC proposal,since the corresponding biotechnologies associated with caiSCs are rapidly developed.Therefore,we call the special attention and efforts from various scientists and clinicians on the caiSCs and believe that the appearance of the caiSCs can shed light on the future of clinical molecular medicine.

Objective:To investigate the clinical and genetic features of a child with Dyschromatosis symmetrica hereditaria (DSH) and variant of the ADAR1 gene. Methods:A child who was admitted to the Department of Dermatology of the First Affiliated Hospital of Zhengzhou University in June 2020 due to irregular pigmented maculopapular rash on the dorsum of hands was selected as the study subject. Whole exome sequencing (WES) was carried out for the child and his similarly affected father, and Sanger sequencing was used to verify the candidate variant. SWISS-MODEL was used to predict the secondary and tertiary structures of the wild-type and mutant ADAR1 proteins.Results:The child, a 13-year-old boy, had symmetrical hyperpigmented and depigmented spots on the back of his hands and was clinically diagnosed with DSH. WES and Sanger sequencing results showed that he and his father had both harbored a heterozygous c. 2858dup (p.T954Dfs*20) truncating variant in exon 10 of the ADAR1 gene. Based on the guidelines from the American College of Medical Genetics and Genomics, the variant was predicted as pathogenic (PVS1+ PM2_Supporting+ PM1+ PP3). Conclusion:The c. 2858dup (p.T954Dfs*20) variant of the ADAR1 gene probably underlay the DSH in this pedigree.

ObjectiveTo explore the effects and mechanisms of modified Dahuang Huanglian Xiexintang on hepatic oxidative stress injury in type 2 diabetes mellitus （T2DM） rats based on the nuclear factor erythroid 2 related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） axis. MethodSix ZDF （fa/+） rats were as assigned to the blank group， and 30 ZDF （fa/fa） rats were used to induce the T2DM model by feeding a high-fat diet. After successful modeling， the rats were randomly divided into the model group， metformin group （0.18 g·kg^-1）， and low， medium， and high dose groups of modified Dahuang Huanglian Xiexintang （0.54， 1.08， 2.16 g·kg^-1）， with six rats in each group. After 12 weeks of drug intervention， the body mass， liver mass， fasting blood glucose （FBG）， and oral glucose tolerance test （OGTT） levels were measured. Serum total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL）， low-density lipoprotein cholesterol （LDL）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） levels were detected using an automatic biochemical analyzer. The pathological changes of liver tissue were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was used to detect the activity of superoxide dismutase （SOD）， reactive oxygen species （ROS）， glutathione peroxidase （GSH-Px）， and the level of malondialdehyde （MDA） in liver tissues. Immunohistochemistry was used to detect the expression of Nrf2 in the liver. Real time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the mRNA and protein expression levels of Nrf2 and HO-1 in liver tissues.

Compared with normal group， the model group showed significantly increased FBG at all time points （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly reduced FBG at 8， 10， 12 weeks. The OGTT results showed that compared with the normal group， the model group had significantly increased blood glucose at all time points （P<0.01）. Compared with the model group， the metformin group showed significantly reduced blood glucose at all time points （P<0.01）， and the medium and high dose groups of modified Dahuang Huanglian Xiexintang showed significantly reduced blood glucose at 90， 120 min （P<0.01）. HE pathology showed clear and regular liver cell structure in the normal group， while the model group showed disordered liver cell structure with visible fat vacuoles and a large number of deformed necrotic cells. The liver tissue structure improved in the metformin group and all doses of modified Dahuang Huanglian Xiexintang， with fewer necrotic cells. Compared with the normal group， the model group showed significantly reduced SOD and GSH-Px levels （P<0.01）， and significantly increased ROS and MDA levels （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly increased SOD and GSH-Px levels （P<0.01）， and significantly reduced MDA levels （P<0.01）. The medium and high dose groups of modified Dahuang Huanglian Xiexintang showed significantly reduced ROS levels （P<0.05）.

Immunohistochemistry showed that compared with the normal group， the model group had significantly reduced positive expression of Nrf2 and HO-1 （P<0.05）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed increased positive expression of Nrf2 and HO-1， with a significant increase in brown-yellow granules around the cell nucleus （P<0.05）. Western blot results showed that compared with the normal group， the model group had significantly reduced protein expression of Nrf2 and HO-1 （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly increased protein expression of Nrf2 and HO-1 （P<0.01）. ConclusionModified Dahuang Huanglian Xiexintang can significantly improve the general condition and pathological changes of liver tissues in T2DM model rats. This improvement is likely achieved through ameliorating hepatic oxidative stress injury via regulating the Nrf2/HO-1 axis.
