To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.

Objective:To screen differentially expressed genes in the retinas of mice with experimental autoimmune uveitis (EAU) through transcriptome sequencing.Methods:Twenty 8-week-old SPF grade male C57BL/6J mice were randomly divided into EAU group and control group by random number table method, with 10 mice in each group.In the EAU group, an emulsion of interphotoreceptor retinoid-binding protein 1-20 and complete Freund adjuvant was injected subcutaneously into the inner side of the hind limbs and intravenously into the tail vein of the mice, and pertussis toxin was injected intraperitoneally to establish the EAU model.In the control group, mice were subcutaneously injected with the corresponding volume of phosphate buffer solution.On the 21st day after model establishment, the anterior segment inflammation of the mouse eyes was examined using a slit-lamp microscope.Retinal blood vessels were observed by fundus photography and clinical inflammation was scored.Hematoxylin-eosin staining was used to observe the morphological changes in the retinal tissues of the two groups.Retinal tissues were collected from two groups of mice.RNA was extracted and cDNA libraries were constructed for transcriptome sequencing.The clusterProfiler package in R programming language was used to screen for differentially expressed genes in EAU, and to conduct GO and KEGG enrichment analyses.The expression of core differentially expressed genes in the retinal tissues was then verified using real-time fluorescent quantitative PCR.The breeding and use of experimental animals were in compliance with the relevant regulations of the Animal Ethics Committee of Anhui Medical University.The study protocol was approved by the Ethics Committee of Anhui Medical University (No.LLSC20221208).Results:On the 21st day after model establishment, the clinical score of the EAU group was 2.83±0.94, significantly higher than 1.89±0.93 of the control group, and the difference was statistically significant ( t=2.290, P<0.05). The retinal blood vessels of mice in the EAU group showed tortuosity and dilation.Histopathological examination revealed a large number of inflammatory cell infiltrations in the retina, indicating successful establishment of the EAU mouse model.Transcriptome sequencing of the mouse retinal tissues identified a total of 32 473 genes, and 154 differentially expressed genes were screened out.Among them, 79 genes were up-regulated with Gm38574, Tmem81, Ptpn7 being top three and 75 genes were down-regulated with Gm19802, Fga, Cyp3a11 being top three.GO enrichment analysis showed that the differentially expressed genes were mostly related to immune response and cytokine action.KEGG pathway enrichment analysis showed that the differentially expressed genes were mainly enriched in the Toll-like pathway and cytokine signaling pathway.Compared with the control group, the relative expression levels of Gm38574, Tmem81, and Ptpn7 in the retinal tissues of the EAU group were up-regulated, while the expression levels of Gm19802, Fga, and Cyp3a11 were down-regulated, and the differences were statistically significant ( t=9.755, 5.358, 6.289, 4.312, 6.577, 6.118; all P<0.05). Conclusions:There are significant differences in the key genes Gm38574, Tmem81, Ptpn7, Gm19802, Fga, and Cyp3a11 in the retinal tissues of EAU mice, mainly corelated with the cytokine interaction pathway, Toll-like receptor signaling pathway.

Objective:To investigate the risk factors for adverse outcomes in elderly patients with nonvalvular atrial fibrilla-tion(AF)after percutaneous left atrial appendage closure(LAAC)combined with radiofrequency ablation(RFA).Meth-ods:A total of 199 elderly AF patients who admitted in Department of Cardiology,Yuhuangding Hospital between Jan 1st,2019 and Aug 17th,2023 and underwent LAAC combined RFA were enrolled.The patients were divided into case group(n=78)and control group(n=121)according to presence of atrial arrhythmia and/or cerebral infarction(CI)within one year after operation.Baseline clinical data,laboratory indexes and color Doppler ultrasound indexes were compared be-tween the two groups,and multivariate Logistic regression was used to analyze the risk factors for postoperative atrial ar-rhythmia and/or CI.Receiver operating characteristic(ROC)curve was constructed to analyze the predictive efficacy of risk factors for atrial arrhythmia and/or CI after operation.Results:Univariate analysis indicated that compared with pa-tients in control group,those in case group had significant higher proportions of preoperative persistent atrial fibrillation(52.60％ vs.37.20％),old myocardial infarction(OMI)(11.50％vs.1.70％)and left atrial diameter(LAD)[(45.47±6.90)mm vs.(43.34±6.64)mm](P＜0.05 or＜0.01).Multivariate Logistic regression analysis indicated history of OMI(OR=8.736,95％CI 1.772～43.069,P=0.008)and LAD(OR=1.053,95％CI 1.006～1.102,P=0.027)were independent risk factors of adverse outcomes in elderly AF patients after LAAC+RFA.ROC analysis indicated that predic-tive efficacy of combined detection of OMI and LAD(AUC=0.663,95％CI 0.593～0.728)for adverse outcomes within 1 year in elderly AF patients after LAAC+RFA was significantly better than those of OMI(AUC=0.549,95％CI 0.477～0.620)and LAD(AUC=0.602,95％CI 0.531～0.671)alone(Z=3.045,2.312,P=0.002,0.021).Conclusion:His-tory of old myocardial infarction and left atrial diameter are independent risk factors for atrial arrhythmia and/or cerebral infarction within 1 year after percutaneous left atrial appendage closure combined with radiofrequency ablation in elderly patients with atrial fibrillation,and the combination has good predictive performance.

BACKGROUND: The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined. METHODS: All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI. RESULTS: Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70). CONCLUSIONS Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

OBJECTIVE: To examine the effectiveness of Chinese medicine (CM) Lianhua Qingwen Granule (LHQW) and Jingyin Gubiao Prescription (JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. METHODS: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group (23,702 cases), LHQW group (11,576 cases), JYGB group (12,112 cases), and dual combination of LHQW and JYGB group (8,854 cases). The length of stay (LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. RESULTS: Patients aged 41-60 years, with nadir threshold cycle (C_T) value of N gene <25, or those fully vaccinated preferred to receive CM therapy. Before or after propensity score matching (PSM), the multiple linear regression showed that LHQW and JYGB treatment were independent influence factors of LOS (both P<0.001). After PSM, there were significant differences in LOS between the LHQW/JYGB combination and the other groups (P<0.01). The results of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS (P=0.032). CONCLUSIONS Patients with a nadir C_T value <25 were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

Lumbar transpedicular dynamic stabilization requires the internal fixation device to continuously provide mechanical support,and the correct placement of screws is the key to ensuring the surgical outcome.The placement of pedicle screws through lumbar transpedicular dynamic stabilization has higher requirements compared with the placement of conventional lumbar pedicle screw,which needs to precisely control the entry point,entry depth,and abduction angle of the pedicle screws,and avoid the potential risks such as the screws penetrating the lateral cortex of the pedicle simultaneously.Based on the clinical experience of our team,this article systematically summa-rizes the placement methods and operational points of pedicle screws through lumbar transpedicular dynamic stabilization,with the aim of providing a reference for clinical practice.

Systemic lupus erythematosus(SLE)complicated refractory immune thrombocytopenia(ITP)is mainly characterized by persistent severe thrombocytopenia and bleeding.Currently,there are no guidelines for treating such ITP.Hereby we reported a patient diagnosed with SLE with more than 10 years history of anemia and thrombocytopenia.This patient had been treated by various immunity inhibitors,such as corticosteroids,cyclosporine,mycophenolate mofetil,azathioprine,tofacitinib and telitacicept,but there was no obvious effect.The platelet count continued to be below 50×109/L.However,when serum cyclosporine trough level between 100 and 150 ng/mL,the clinical efficacy was improved and the platelet count was above 100×109/L.The patient was followed up for more than 6 months,and no recurrence of disease was found.Cyclosporine combined with low-dose glucocorticoid is safe and effective for SLE associated ITP.Therapeutic drug monitoring is a powerful tool for improving clinical efficacy and ensuring drug safety.

In view of the characteristics of H5N6 subtype avian influenza virus(AIV)that it has both high pathogenicity and the risk of cross-species transmission,posing a serious threat to the poultry farming industry and public health security,in order to effectively prevent and control the spread of H5N6 avian influenza,a rapid,sensitive and specific detection technolo-gy was established in this study.The specific monoclonal antibodies against the neuraminidase N6 protein of avian influenza A virus subtype H5N6 were obtained through hybridoma and monoclonal antibody technology.These antibodies were coupled and labeled with carboxyl-functionalized fluorescent quantum dots,along with previously prepared specific antibodies against the hemagglutinin H5 protein.A rapid fluorescence immunochromatographic detection method for the H5N6 subtype of avian influ-enza virus was established according to the principle of double-antibody sandwich immunochromatography.This method a-chieved a detection sensitivity of 1 ng/mL for recombinant hemagglutinin H5 subtype protein and 0.1 ng/mL for recombinant neuraminidase N6 subtype protein.Moreover,the method exhibited no cross-reactivity with other influenza subtypes or patho-gens,such as Newcastle disease(ND),infectious bronchitis(IB),and infectious laryngotracheitis(ILT),thus demonstrating good specificity.The method effectively identified the highly pathogenic avian influenza virus H5 subtype and directly distin-guished the H5N6 subtype with good accuracy.The fluorescent quantum dot immunochromatographic typing detection method established herein met the sensitivity,specificity,and accuracy requirements for H5N6 subtype detection,and can be further used for rapid detection of the H5 and H5N6 subtypes of avian influenza virus.
