Objective To investigate the expression of centromeric protein F(CENPF)and microribonucleic acid 1-3p(miR-1-3p)in the serum of patients with advanced gastric cancer and their correlation with prognosis.Methods Sixty patients with advanced gastric cancer admitted to our hospital from March 2019 to March 2020 were collected as the study group,while 60 healthy volunteers who underwent physical examinations at our hospital's physical examination center during the same period were collected as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)method was applied to detect the expression levels of serum CENPF and miR-1-3p in each group;Pearson method was applied to analyze the correlation between serum levels of CENPF and miR-1-3p;Kaplan-Meier method was applied to analyze the relationship between the expression of CENPF,miR-1-3p,and prognosis in patients with advanced gastric cancer;and COX regression was applied to analyze risk factors affecting the prognosis of patients with advanced gastric cancer.Results Compared with the control group,the CENPF level in the study group was obviously increased,while the miR-1-3p level was obviously reduced(P＜0.05).The correlation analysis results showed that there was a negative correlation between serum CENPF and miR-1-3p levels in patients with advanced gastric cancer(r =-0.650,P＜0.001).There were obvious differences in CENPF and miR-1-3p levels among different TNM stages and lymph node metastasis status(P＜0.05).The 3-year survival rate of patients in the high expression group of CENPF was 19/30(63.33%),which was obviously lower than that in the low expression group,28/30(93.33%)(χ2 = 7.954,P＜0.001);the 3-year survival rate of patients in high expression group of miR-1-3p was 29/30(96.67%),which was obviously higher than that in the low expression group,18/30(60.00%)(χ2 = 11.882,P = 0.001).Multivariate COX regression analysis showed that TNM staging,lymph node metastasis,CENPF,and miR-1-3p expression were risk factors affecting the prognosis of patients with advanced gastric cancer(P＜0.05).Conclusion The serum CENPF level in patients with advanced gastric cancer obviously increase,while miR-1-3p level obviously decrease,both of which are related to prognosis.

Objective We aimed to establish the benchmark characteristic map of Fuzi decoction and the determination method of multi-index components,and to clarify the key quality attributes of Fuzi decoction.Methods Fifteen batches of Fuzi decoction substance benchmarks samples were prepared;the high-performance liquid chromatography(HPLC)characteristic spectrum of Fuzi decoction was established;and characteristic peak attribution and similarity analysis were performed.Ginsenosides Rg1,Re,Rf,and Rb1 were used as the index components to establish a method to determine ginseng content in Fuzi decoction.The value range of each quality control index was set at a limit of 70%-130%of the average value,and the quantity transfer analysis was performed on the material basis of 15 Fuzi decoction batches.Results The characteristic spectra of the 15 Fuzi decoction batches had 12 common peaks,and seven characteristic peaks of gallic acid,catechin,paeoniflorin,ginsenosides Rg1,Re,and Rb1,and atractylenolide Ⅲ were identified,with a similarity of more than 0.98.Ginsenosides Rg1,Re,Rf,and Rb1 content ranges were 0.51-0.94,0.34-0.62,0.14-0.27,and 0.41-0.76 mg/g,respectively.The transfer rates of ginsenosides Rg1 and Re,Rf,and Rb1 were 12.05%-26.91%,11.15%-43.71%,and 10.53%-33.23%,respectively.Conclusion The characteristic HPLC of Fuzi decoction and the determination method of Fuzi decoction ginseng content established in this study are accurate,reproducible,and stable,laying the foundation for the quality evaluation of the key chemical properties of Fuzi decoction and its preparation.

italic>Anoectochilus roxburghii liquid (spray, a hospital preparation of Wu Mengchao Hepatobiliary Hospital of Fujian Medical University) has shown a good clinical treatment effect during the COVID-19 pandemic, but its material basis and mechanism of action are still unclear. In this study, network pharmacology and molecular docking methods were used to predict the molecular mechanism of A. roxburghii liquid against COVID-19, and pharmacodynamic experiments in vitro were conducted to study the interaction between the current targets with clear preventive and therapeutic effects and the key components of A. roxburghii liquid. UPLC-MS and database were used to compare and analyze the active ingredients in the liquid, and 17 potential active ingredients with good drug-like properties were screened by in vivo pharmacokinetics process in SwissADME database. SwissTargetPrediction and GeneCards were searched to find 93 common targets. Cytoscape 3.8.2 software was used to construct the "component-target" network map, and the Metascape platform was used for gene function annotation and pathway enrichment analysis. It was found that the extract could regulate the positive response to external stimuli, inflammatory response, cytokine production and other biological processes by binding the active ingredients such as isorhamnetin, kaempferol, luteolin, quercetin and apigenin to the common targets (NOS3, MPO, MMP3, etc.), and play an anti-COVID-19 role. In the angiotensin-converting enzyme 2 (ACE2) activity inhibition assay, it was found that the stock solution of A. roxburghii liquid (for spray), and the supernatant after removing polysaccharides (mainly containing flavonoids) could to some extent inhibit the activity of ACE2. Crucially, in the experiment of 2019-nCOV-S pseudovirus infecting HEK-293T-ACE2 cells, we found that A. roxburghii liquid may exert anti-COVID-19 effects by blocking the binding of SARS-CoV-S protein to ACE2.

Purpose To explore the predictive value of nomogram model for invasive breast cancer with axillary lymph node metastasis.Materials and Methods Retrospective analysis was made on 122 patients suspected to be breast cancer in the General Hospital of Ningxia Medical University from September 2020 to March 2022.According to whether there was axillary lymph node metastasis,all subjects were divided into 57 patients in the metastasis group and 65 patients in the non-metastasis group.All lesions were pathologically confirmed by surgery.The two groups received synthesis of magnetic resonance imaging(syMRI),dynamic contrast enhancement magnetic resonance imaging(DCE-MRI)and diffusion weighted imaging(DWI)scans.The syMRI parameters[including T1,T2,proton density(PD)],DCE-MRI time signal intensity curve,apparent diffusion coefficient(ADC)value of breast lesions were measured.Compared the difference of parameters between the two groups,and screened the independent risk factors of invasive breast cancer with axillary lymph node metastasis.Results Logistic regression results showed that Ki-67(OR=2.971,95%CI 1.306-6.762,P=0.009),lesion size(OR=1.652,95%CI 1.067-2.556,P=0.024),ADCratio(OR=1.685,95%CI 1.014-2.801,P=0.044),T2ratio(OR=3.015,95%CI 1.433-6.340,P=0.003),PDratio(OR=2.782,95%CI 1.471-5.262,P=0.002)were independent risk factors for invasive breast cancer with axillary lymph node metastasis.The comparison of the five models showed that the Logistic regression model had the best performance,with the area under curve of 0.729(95%CI 0.621-0.789),the accuracy,specificity and sensitivity were 70.65%,62.79%and 77.55%,respectively.The accuracy of the nomogram model was tested,and C-index=0.844,the accuracy of the nomogram model established was good,cut-off risk was 0.468,and the cut-off score was 143.50,which means that when the total score exceeds 143.50,the risk of axillary lymph node metastasis would be higher than 46.8%.Conclusion Nomogram model has a good predictive ability for invasive breast cancer patients with axillary lymph node metastasis.

Objective:To determine incidence of seasonal influenza virus infection in the community and to analyze the factors influencing seasonal influenza virus infection.Methods:This study recruited residents aged 6-59 years to build a cohort in 15 villages/streets in Macheng city in November 2019. Meanwhile, a cross-sectional baseline survey was conducted immediately to collect sera, information on demographics and child protection knowledge, behaviors, as well as attitudes using a questionnaire from the participants enrolled in the cohort (i.e., before the influenza epidemic season). In July 2020, a cross-sectional follow-up survey was conducted to collect sera once again (i.e., after the influenza season). Paired sera from the two cross-sectional surveys were tested for influenza virus-specific antibodies by hemagglutination inhibition (HI) test or micro-neutralization (MN) test using a circulating representative strain of each subtype/lineage of influenza virus as the test antigen. The infections with influenza virus subtype/lineage was confirmed if there was a four-fold or more increase in titers of antibodies against circulating representative strain of the subtype/lineage of influenza virus. Factors influencing infection with influenza A (H3N2) and B/Victoria viruses were analyzed using univariable and multivariable logistic regression.Results:In November 2019, 800 study participants were enrolled in the cohort, including 340 children aged 6-17 years and 460 adults aged 18-59 years; 605 study participants (including 224 children and 381 adults) were followed up in July 2020 and their paired sera were obtained before and after the influenza season. 25.3% (153/605) of the participants were confirmed to be infected with at least one subtype/lineage of seasonal influenza virus by HI and MN tests. The overall incidence of influenza viruses of all subtypes/lineages in children was 44.2% (95% CI: 37.6%-50.8%) which was significantly higher than the incidence of 14.1% in adults (95% CI: 10.7%-17.7%). Children had the highest incidence of influenza A (H3N2) virus infection, followed by B/Victoria. MN or HI antibody titers in A (H3N2)[ OR=0.88 (95% CI: 0.84-0.93)] and B/Victoria[ OR=0.97 (95% CI: 0.95-0.99)] before the influenza season were significantly associated with whether children were infected with that subtype/lineage of influenza virus. Conclusions:The residents aged 6-59 years in Macheng city had a substantial incidence of seasonal influenza virus infection during the influenza season from winter 2019 to spring 2020. Notably, almost half of children aged 6-17 years have been infected with seasonal influenza virus. Higher titers of HI/MN antibodies against seasonal influenza virus before the influenza season would be likely to reduce the risk of infection with influenza A (H3N2) and B/Victoria.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Refractory acute T-lymphoblastic leukemia (T-ALL), which is characterized by a low sensitivity to conventional induction therapy and poor prognosis, poses significant challenges during treatment. This study reported a case of refractory T-ALL patient with mutations in the JAK1, JAK3, and STAT5B genes from Nanjing University’s Gulou Hospital. Following an unsuccessful course of standard VDLP regimen chemotherapy, the treatment was modified to include ruxolitinib in combination with venetoclax and azacitidine. Subsequent to this therapy, the patient achieved bone marrow minimal residual disease (MRD) negativity. Notably, pleural effusion and mediastinal mass significantly improved the post-chest cavity infusion of dexamethasone combined with etoposide at the same stage. The patient also underwent allogeneic hematopoietic stem cell transplantation upon achieving bone marrow remission and was followed up until January 2024. Ruxolitinib combined with venetoclax and azacytidine has shown promising efficacy and safety in treating refractory T-ALL harboring the JAK1, JAK3, and STAT5B mutations, providing a novel therapeutic approach for such patients.

Objective:To investigate the efficacy of posterior reduction and fixation combined with pedicle subtraction osteotomy (PSO) in the treatment of ankylosing spondylitis (AS) kyphotic deformity complicated by upper cervical spine injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 8 patients with AS kyphotic deformity complicated by upper cervical spine injury, who were admitted to First Affiliated Hospital of Xinjiang Medical University from October 2010 to December 2022. All were males, aged 32-58 years [(46.9±8.7)years]. Acute injury was found in 1 patient and chronic injuries in 7 patients, including 3 with cervicothoracic kyphotic deformity and 5 with thoracolumbar kyphotic deformity. Five patients were complicated by odontoid fractures, 1 by C 2-C 3 fracture and 2 by atlantoaxial dislocation. According to American Spinal Injury Association (ASIA) scale, 2 patients were with grade C, 3 with grade D, and 3 with grade E. The patients were treated with posterior upper cervical reduction and fixation combined with cervicothoracic PSO or thoracolumbar PSO respectively according to the location of the deformity. The operation time and intraoperative blood loss were recorded. Neck disability index (NDI), visual analogue scale (VAS), C 0-C 2 angle, C 1-C 2 angle, cervical lordosis angle (CL), head tilt angle (HT), chin-brow vertical angle (CBVA), cervical sagittal vertical axis (CSVA), and sagittal vertical axis (SVA) were compared before surgery, at 1 week and 3, 6, 12 months after surgery, and at the last follow-up. The healing of fractures and fusion of osteotomy site were recorded at 12 months after surgery. Recovery of neurological function was observed at the last follow-up. Incidence of complications was observed. Results:Patients were all followed up for 12-24 months [(17.0±5.4)months]. The operation time was 5.5-7.2 hours [(6.2±0.6)hours] and the intraoperative blood loss was 480-800 ml [(629.4±124.0)ml]. The NDI scores at 1 week and 3, 6, 12 months after surgery, and at the last follow-up were (14.6±2.6)points, (13.6±2.8)points, (12.8±2.4)points, (12.8±2.7)points, and (12.8±2.6)points respectively, significantly lower than (29.6±8.5)points preoperatively ( P<0.01). There were no significant differences in NDI scores at various time points after surgery ( P>0.05). The VAS scores were 2.0(1.0, 3.0)points, 1.5(1.0, 2.0)points, 0.5(0.0, 1.8)points, 0.5(0.0, 1.7)points, and 0.5(0.0, 1.8)points respectively, significantly lower than 3.5(3.0, 4.8)points preoperatively ( P<0.01). The VAS score at 3 months postoperatively was lower than that at 1 week postoperatively ( P<0.05), and the VAS score at 6 months postoperatively was lower than that at 3 months postoperatively ( P<0.05). There were no statistically significant differences in VAS scores at 6, 12 months postoperatively, and at the last follow-up ( P>0.05). There were no statistically significant differences between C 0-C 2 angle and C 1-C 2 angle preoperatively and at different time points postoperatively ( P>0.05). At 1 week and 3, 6, 12 months postoperatively and at the last follow-up, the CL values were -8.5(-5.3, -11.9)°, -8.6(-5.5, -11.9)°, -8.4(5.2, -12.1)°, -8.8(-5.6, -12.4)°, and -8.7(-5.3, -12.5)° respectively, significantly higher than 1.2(9.5, -4.8)° preoperatively ( P<0.01); the HT values were 6.1(4.5, 9.6)°, 6.1(4.3, 9.4)°, 6.0(4.2, 8.9)°, 6.0(4.2, 9.2)°, and 6.1(4.3, 9.2)° respectively, significantly lower than 17.0(10.3, 22.0)° preoperatively ( P<0.01); the CBVA values were (23.2±5.0)°, (23.1±4.8)°, (23.0±4.7)°, (23.1±4.7)°, and (23.1±4.9)° respectively, significantly lower than (44.1±9.8)° preoperatively ( P<0.01); the CSVA values were 5.2(4.2, 7.5)cm, 5.4(4.1, 7.1)cm, 4.7(4.0, 7.4)cm, 5.4(4.1, 7.0)cm, and 5.1(4.3, 6.5)cm respectively, significantly shorter than 9.0(7.8, 9.3)cm preoperatively ( P<0.01); the SVA values were 7.7(6.2, 13.7)cm, 7.5(6.0, 13.4)cm, 7.6(6.2, 13.2)cm, 7.4(6.3, 13.1)cm, and 7.5(6.2, 13.2)cm respectively, significantly shorter than 16.8(8.2, 27.2)cm preoperatively ( P<0.05). There were no statistically significant differences among CL, HT, CBVA, CSVA, and SVA values at different time points after surgery ( P>0.05). All the fractures healed at 12 months after surgery and Bridwell grade I healing was achieved at all the osteotomy sites. At the last follow-up, all the patients were classified as ASIA grade E, significantly improved compared with preoperatively ( P<0.01). One patient had transient C 8 nerve paralysis after surgery and recovered after 4 weeks′ treatment. The remaining patients did not develop any infection or internal fixation-related complications, such as broken rods, broken screws, or loose screws. Conclusion:For AS kyphosis deformity complicated with upper cervical injury, posterior reduction and fixation combined with cervicothoracic or thoracolumbar PSO can effectively promote functional recovery, relieve pain, maintain overall trunk balance, improve neurological symptoms, and reduce the incidence of complications.

AIM To investigate the impact of the combination use of Caragana sinica Radix and Astragali Radix on a rat model of diabetic kidney disease(DKD).METHODS The SD rats were randomly divided into the normal group,the model group,the Engelgin group,the Caragana sinica Radix group,the Astragali Radix group and the Caragana sinica Radix-Astragali Radix compatibility group,with 10 rats in each group.Following the successful establishment of a DKD model by unilateral amputate renal combined with intraperitoneal injection of streptozotocin(STZ),the corresponding gastric gavage of drugs were administered for 8 weeks.The rats had their 24 h urinary microalbumin(24 h U-mALB)detected at 0,4 and 8 weeks;their levels of Scr,BUN,CysC,MDA and SOD activity detected by ELISA;their renal ROS expression detected by fluorescence probe method;their renal pathological changes observed by HE,PAS,Masson and PASM-Masson staining;their renal expressions of NOX4,Drp1,MFN2 and P62 detected by immunohistochemistry;and their renal expressions of PINK1,MFN2,Parkin,LC3-Ⅱ/Ⅰ,P62 and p-Drp1 proteins detected by Western blot.RESULTS Compared with the model group,each treatment group displayed lower contents of 24 h U-mALB,BUN,Scr and CysC in the serum of rats(P＜0.01);reduced pathological structure damage of the renal tissue;decreased MDA level in serum and kidney(P＜0.01);increased SOD activity(P＜0.01);increased renal protein expressions of PINK1,MFN2,Parkin and LC3-Ⅱ/Ⅰ(P＜0.05,P＜0.01);and decreased protein expressions of p-Drp1 and P62(P＜0.01).And the Astragali Radix group and the Caragana sinica Radix-Astragali Radix compatibility group took the lead(P＜0.05,P＜0.01).CONCLUSION Upon the rat model of DKD,the compatibility of Caragana sinica Radix and Astragali Radix may alleviate their renal pathological damage and improve their renal function by activating the mitochondrial autophagy to improve mitochondrial dynamics and inhibit their oxidative stress via PINK1/MFN2/Parkin pathway.
