Purpose: Zinc finger protein 639 (ZNF639) is often found within the overlapping amplicon of PIK3CA, and previous studies suggest its involvement in the pathogenesis of esophageal and oral squamous cell carcinomas. However, its expression and significance in breast cancer remain uncharacterized. Methods: Immunohistochemical analysis of ZNF639 was performed using tissue microarrays.Functional studies, including colony formation, Transwell cell migration, and in vivo metastasis, were conducted on breast tumor cells with ZNF639 knockdown via small interfering RNA transfection. Results: Reduced ZNF639 immunoreactivity was observed in 82% of the breast cancer samples, independent of hormone receptor and human epidermal growth factor receptor 2 status. In multivariate Cox regression analyses, ZNF639 expression was associated with favorable survival outcomes, including recurrence-free survival (hazard ratio, 0.35; 95% confidence interval [CI], 0.14–0.89) and overall survival (hazard ratio, 0.41; 95% CI, 0.16– 1.05). ZNF639 knockdown increased clonogenicity, cell motility, and lung metastasis in NOD/ SCID mice. Following the ZNF639 knockdown, the expression of Snail1, vimentin, and C-C chemokine ligand 20 (CCL20) was upregulated, and the changes in cell phenotype mediated by ZNF639 were reversed by the subsequent knockdown of CCL20. Conclusion Low ZNF639 expression is a novel prognostic factor for recurrence-free survival in patients with breast cancer.

ObjectiveTo understand the whole genome characteristics and the information for genetic evolution in the two coxsackievirus A2 (CVA2) strains isolated from patients with herpangina in Shanghai, and to provide a scientific basis for the prevention and treatment of herpetic angina. MethodsTwo CAV2 strains isolated from patients with herpetic angina in Shanghai were performed whole genome sequencing and analysis for phylogenetics, nucleotide homology, and evolution. ResultsA phylogenetic analysis of the VP1 region revealed that the two Shanghai strains both belonged to CVA2 genotype D, with the highest homology to OL357660, a strain from Yunnan. The average nucleotide identity (ANI) of the whole genome between the two Shanghai strains was 98.88%, and the ANI of the whole genome comparisons to other CVA2 genotype D strains and CVA2 genotypes A-C strains ranged from 84.64% to 97.42% and from 79.21% to 84.20%, respectively. The two Shanghai strains had low homology in the 3D region compared to the existing CVA2 strains. The phylogenetic analysis and sliding window nucleotide similarity analysis indicated that the two Shanghai strains and the Yunnan OL357660 strain might constitute a new genetic lineage. ConclusionThe two CVA2 strains isolated for the first time in Shanghai are assigned to genotype D (GenBank: PQ130039 and PQ130040), which is identical to the existing subtype prevalent in China. As represented by the Shanghai strains, a new CVA2 genetic lineage is been identified. This study has enriched the data on genetic evolution and genetic variation of CVA2 in Shanghai, indicating the requirement to strengthen surveillance for the epidemiological pattern of CVA2.

In this report,we described a case of a clinical practice,in which the clinical pharmacists was involved in the treatment of a soft tissue sarcoma patient,who was diagnosed with mental disorders induced by regorafenib.The patient was complicated with hypoproteinemia,hepatic insufficiency,leukoencephalopathy and other diseases.Before the treatment,the patient's mental was normal.After continuous administration of regorafenib(40 mg,po,qd)for 5 days,the patient has a sudden loss of consciousness.Clinical pharmacists excluded the possibility of mental disorders caused by tumor brain metastases,exacerbation of leucoencephalopathy or hepatic encephalopathy and the drugs used together.They determined that mental disorders were likely to be related to the use of regorafenib through the association evaluation of adverse reactions.It was considered to be an adverse reaction induced by regorafenib.Therefore,regorafenib treatment was temporarily suspended and symptomatic treatment was given.After 5 days,the patient's mental state improved.In addition,clinical pharmacists monitored the patient for symptomatic treatment,and provided appropriate antitumor drug treatment recommendations based on evidence-based evidence.This case suggests that the clinical use of regorafenib should be vigilant against mental disorders adverse reactions,do a good job of pharmaceutical care,and timely drug analysis and symptomatic treatment after adverse reactions.

Aim To investigate the possible mechanism of action of Qingjie Huagong decoction(QJHGD)on acute lung injury(ALI)associated with severe acute pancreatitis(SAP)using network pharmacology,and to verify it by animal experiments.Methods The TC-MSP,BATMAN-TCM,ETCM,and SwissTargetPredic-tion databases were searched to obtain the action tar-gets of the blood-entering active ingredients of each drug in the QJHGD.The GeneCard database was searched to obtain SAP-ALI disease targets.The drug targets and disease targets were intersected to obtain common targets.Subsequently,the common targets were analyzed by STRING database and Cytoscape 3.7.1 software for protein interaction network analysis.GO and KEGG enrichment analysis was performed with the help of DAVID database.Finally,the key signa-ling pathways were verified by animal experiments.Results A total of 28 active ingredients were screened out for the treatment of SAP-ALI with 42 common tar-gets.PPI network analysis showed that STAT3,IL-6,and TGFB1 might be core targets;GO and KEGG en-richment analysis mainly involved cell proliferation,PI3K/AKT signaling pathways,etc.Animal experi-ments confirmed that QJHGD could improve the pathol-ogy of pancreas and lung tissues in SAP-ALI rat mod-el,down-regulate the expression levels of α-amylase,lipase,IL-1 β,IL-6,and TNF-α in serum,and down-regulate the expression levels of proteins and mRNAs related to PI3K/AKT1 signaling pathway in lung tis-sues.Conclusion QJHGD synergistically treats SAP-ALI through multi-component,multi-target,and multi-pathway,with a mechanism that may be related to the inhibition of PI3K/AKT signaling pathway activation.

Aim To investigate the effects of multi-gly-cosides of Tripterygium wilfordii(GTW)on mitochon-drial dynamics-related proteins and the mechanism of nephroprotective effects in IgA nephrophathy(IgAN)rats.Methods SPF grade male SD rats were random-ly divided into the Control group,modelling group,prednisone group(6.25 mg·kg·d-1)and GTW group(6.25 mg·kg·d-1).The IgAN rat model was established by the method of"bovine serum albumin(BSA)+carbon tetrachloride(CCl4)+lipopolysac-charide(LPS)".The total amount of urinary protein(24 h-UTP)and erythrocyte count in urine were meas-ured in 24 h urine.Blood biochemistry of serum albu-min(ALB),alanine aminotransferase(ALT),urea ni-trogen(BUN),and creatinine(Scr)were measured in abdominal aorta of the rats;immunofluorescence and HE staining were used to observe the histopathology of the kidneys;RT-PCR and Western blotting were used to detect the mRNA and protein expression levels of key proteins regulating mitochondrial division and fu-sion:dynamin-related protein 1(Drp1),mitochondrial fusion protein 1(Mfn1),and mitochondrial fusion pro-tein 2(Mfn2),and PTEN-induced putative kinase 1(Pink1),in the kidney tissue of rats.Results GTW significantly reduced urinary erythrocyte count and 24 h-UTP,decreased serum ALT,BUN and Scr levels,in-creased serum ALB levels,improved renal histopatho-logical status in IgAN rats,increased the protein and mRNA expression levels of Mfn1,Mfn2,and Pink1,and decreased the protein and mRNA expression levels of Drp1 in renal tissues.Conclusions GTW may regu-late mitochondrial structure and maintain the dynamic balance of mitochondrial dynamics by promoting the ex-pression of Mfn1,Mfn2,Pink1 and decreasing Drp1.This may result in a reduction in urinary erythrocyte counts and proteinuria,and an improvement in renal function.

Aim To explore the mechanism of action of Tripterygium glycosides tablets on kidney of rats with IgA nephropathy based on inflammation-related path-ways.Methods Forty-five male SD rats of SPF grade were randomly divided into control group and modeling group.In addition to the blank group,the modeling group used the combination of bovine serum albumin(BSA)+carbon tetrachloride(CC14)+lipopolysac-charide(LPS)to establish the IgA nephropathy rat model.Successfully modeled rats were randomly divid-ed into the model group,the prednisone group and Tripterygium glycosides tablets group,and the treat-ment group was given the drug by gavage from the 13 th week,and the 24 hours urine,blood and kidney tis-sues of the rats were collected and examined after 4 weeks of the administration of the drug.Urine erythro-cyte count,quantitative 24-h urine protein(24 h-UTP),urea nitrogen(BUN),and blood creatinine(Scr)were detected in each group;serum interleukin 1β(IL-1β)and tumor necrosis factor α(TNF-α)were detected by enzyme-linked immunosorbent assay(Elisa);the pathological changes in the renal tissues of the rats in each group were observed by horizontal hematoxylin-eosin(HE)staining;and the renal tis-sues in each group were observed by Western blotting.The expressions of LIGHT,HVEM,LTβR proteins and their mRNAs in rat kidney tissue were detected by Western blot and real-time fluorescence quantitative polymerase chain reaction(RT-PCR).Results Tripterygium glycosides tablets significantly reduced the levels of urinary erythrocyte count,24 h-UTP,BUN,and Scr in IgA nephropathy rats(P＜0.01),improved renal histopathology,lowered the levels of se-rum inflammatory factors IL-1β and TNF-α(P＜0.01),and lowered the levels of LIGHT,HVEM,LTβR proteins and their mRNA expression in renal tis-sues(P＜0.01).Conclusions Tripterygium glyco-sides tablets may inhibit the immune response and re-duce the release of inflammatory factors by down-regu-lating the LIGHT-HVEM/LT(3R pathway,thus reduc-ing the inflammatory response,lowering the urinary e-rythrocytes and urinary proteins,improving the renal nephron pathologic injury,and protecting the renal function.

Objective To investigate the clinical efficacy of body-surface guide plates for lateral segmental positioning in the thoracolumbar spine.Methods From March 2018 to March 2021,768 gerontal patientss underwent percutaneous vertebro-plasty with balloon dilatation due to thoracolumbar compression fracturess,356 males and 412 females.aged from 64 to 92 years old with an average of(77.9±13.5)years old.All patients were treated in hospital within 1 week after injury.All patients underwent preoperative localization,and were divided into localization plate group and locator group according to different lo-calization methods.There were 390 patients in the localization plate group,180 males and 210 females,aged from 64 to 92 years old,with an average age of(78.4±14.3)years old.There were 378 patients in the locator group,176 males and 202 fe-males,aged from 64 to 90 years old,with an average age of(77.5±13.4)years old.After preliminary positioning with the above two methods,skin markers were made,cloth was routinely disinfected,and the spinal lateral position was fluoroscopically ex-amined after the fine needle was inserted into the marked point and the vertical body at the near tail end.The accuracy of the original positioning method was evaluated.The number of times,time and accuracy of positioning of the two groups of patients were compared and analyzed.Results The specific data of patient positioning in the two groups were collected for statistical analysis.The number of times of fluoroscopy in the positioning plate group and the locator group was(3.3±0.5)times and(5.0± 1.2)times,and the positioning time was(60.4±9.4)s and(105.0±30.9)s,respectively.The accuracy of fluoroscopy was 97.5％(380/390)and 85.7％(324/378),respectively,with statistical significance(P＜0.05).Conclusion The lateral seg-mental positioning plate of the body surface spine has the advantages of simple operation,accurate positioning,and reducing X-ray radiation for patients,which is worthy of clinical application.

Objective:To elucidate the etiological and epidemiological characteristics and epidemiological patterns of viral acute respiratory infections (ARI) in Shanghai during 2023, with the aim of providing robust laboratory evidence for effective prevention and control strategies against related respiratory diseases and facilitating risk assessment.Methods:Respiratory pathogens were detected in the clinical surveillance specimens submitted by sentinel hospitals through multiplex PCR, as part of the multi-pathogen surveillance of acute respiratory infections in Shanghai during 2023. The obtained detection result were statistically analyzed in conjunction with sample information.Results:The positive detection rate of viral pathogens in 2023 was 21.17% (984/4 648), with rates of 33.53% (504/1 503) observed in ILI cases and 15.62% (480/3 145) in SARI cases. Influenza A virus (FluA) was the predominant virus detected, accounting for 13.7% (637/4 648). Other viruses identified in the surveillance samples included influenza B virus (Flu B), human rhinovirus/enterovirus (HRV/HEV), respiratory syncytial virus (RSV), human metapneumovirus (HMPV), parainfluenza virus (PIV), adenovirus (ADV) and human bocavirus (HBoV). Regarding temporal distribution, HRV/HEV and RSV exhibited the highest detection rates during the second quarter at 2.27% each (28/1 236). PIV had its peak during the third quarter at a rate of 2.49% (35/1 405), and HMPV showed prevalence mainly during the third and fourth quarters, with detection rates of 2.63% (37/1 405) and 2.35% (32/1 360), respectively.Conclusions:In acute respiratory infection surveillance cases in Shanghai in 2023, Flu A emerged as the predominant respiratory pathogen. The detection rate of HMPV ranked second only to Flu A, while other respiratory viruses such as HRV/HEV, RSV, and PIV were detected during different seasons and co-circulated. The prevalence of various respiratory viruses varied among different infected populations and over times.
