Objective To analyze the epidemiological characteristics and spatiotemporal clustering of varicella in Lu'an City from 2005 to 2023, and to provide a scientific basis for optimizing varicella prevention and control strategies. Methods Data on varicella cases were collected through the Chinese Center for Disease Control and Prevention Information System. Descriptive epidemiology, temporal trend analysis, seasonal analysis, spatiotemporal clustering analysis, and spatial autocorrelation analysis were conducted using QGIS, JoinPoint, SaTScan and GeoDa software. Results The average annual reported incidence rate of varicella in Lu'an City from 2005 to 2023 was 34.55/100,000, showing a trend of initial increase followed by a decrease. The peak incidence occurred from October to January of the following year (RR=1.97, LLR=1743.95, P=0.001). Students aged 0 to 19 was the primary affected group. Spatiotemporal scan analysis revealed four types of spatiotemporal clusters, with the cluster in Jin'an District from October 2017 to December 2023 being particularly prominent (RR=2.87，LLR=1734.15，P<0.001). Spatial autocorrelation analysis indicated significant clustering of varicella cases in the main urban area (Moran's I=0.216，Z=4.786，P=0.003). Conclusion The incidence of varicella in Lu'an City exhibits distinct seasonal and spatial clustering, and schools and kindergartens in the main urban area are the key to varicella prevention and control. It is necessary to enhance the monitoring of disease outbreaks during peak periods and in key areas, and to increase the two-dose vaccination rate for varicella in areas with case aggregation and among key populations.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Aim To investigate the effects of Radix Angelica Sinensis and Radix Hedysari ultrafiltration(RAS-RH)on oxidative stress and inflammatory injury of human umbilical vein endothelial cells(HUVECs)induced by ionizing radiation.Methods The model of HUVECs damage induced by 6 Gy X-rays was estab-lished.HUVECs were treated with different concentra-tions of RAS-RH(100,200,400 μg·L-1).The proliferative activity of HUVECs was detected by CCK-8 method,the structural changes of mitochondria were observed by transmission electron microscope,the level of ROS was detected by DCFH-DA probe,the change of intracellular mitochondrial membrane potential was detected by JC-1 kit,and the apoptosis and cycle were detected by flow cytometry.The contents of IL-6 and TNF-α in cells were detected by ELISA.The activities of MDA,CAT,SOD and GSH-PX were detected by biochemical kit.The gene expression levels of Nrf2,HO-1,NF-κB,eNOS and IL-6 were detected by qRT-PCR,and the expression levels of Nrf2,HO-1,eNOS,NF-κB,p-NF-κB and IL-6 protein were detected by Western blot.Results Compared with the model group,RAS-RH could increase the activity of HUVECs induced by ionizing radiation,decrease the rate of ap-optosis,decrease the level of intracellular ROS,re-duce the injury of intracellular mitochondria,increase the level of mitochondrial membrane potential,promote the expression of Nrf2,HO-1 and eNOS,and inhibit the expression of NF-κB and IL-6.Conclusions RAS-RH has anti-radiation,antioxidant and anti-in-flammatory effects,which may reduce the oxidative stress and inflammatory damage of HUVECs induced by ionizing radiation by activating the activity of Nrf2/HO-1 signal pathway,thus promoting the activity of cell proliferation.

IPCL was reclassified according to Arima classification. The depth of infiltration determined by pathology was the gold standard. The sensitivity, the specificity, the positive predictive value and the negative predictive value of B2-Arima combined classification in predicting the invasion depth of SESCC were analyzed.Results:In the 76 cases of type B2 IPCL lesions, 31 cases (40.79%) were T1a-MM/T1b-SM1 SESCC. The sensitivity, the specificity, the positive predictive value, the negative predictive value and the diagnostic accuracy of type B2 IPCL to predict T1a-MM/T1b-SM1 SESCC were 70.45% (31/44), 79.64% (176/221), 40.79% (31/76), 93.12% (176/189), and 78.11% (207/265), respectively. After Arima classification, the above corresponding indicators of type B2-4ML and type B2-AVA-4M IPCL in predicting T1a-MM/T1b-SM1 SESCC were 61.36% (27/44), 88.24% (195/221), 50.94% (27/53), 91.98% (195/212), 83.77% (222/265) and 38.64% (17/44), 94.57% (209/221), 58.62% (17/29), 88.56% (209/236), 85.28% (226/265), respectively.Conclusion:B2 IPCL combined with Arima classification can improve the diagnostic accuracy of T1a-MM/T1b-SM1 ESSCC.

Objective:To compare the diagnostic efficacy of 22 G fine needle aspiration (FNA) needles and 22 G end-cutting fine needle biopsy (FNB) needles for solid pancreatic lesion using both cytological and histological examination.Methods:Clinical data of 116 patients who underwent endoscopic ultrasound-guided fine needle aspiration/biopsy (EUS-FNA/FNB) at the Digestive Endoscopy Center of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from June 2022 to March 2023 were retrospectively analyzed. Sixty-three patients sampled with 22 G FNA needles were the FNA group, and 53 sampled with 22 G FNB needles were the FNB group. The diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and cytological and histological diagnostic yield of FNA needles and FNB needles for solid pancreatic lesions were compared.Results:There were no significant differences in age, gender, lesion location, lesion size, or the number of passes between the FNA group and the FNB group ( P>0.05). There were no significant differences in the diagnostic accuracy [93.7% (59/63) VS 90.6% (48/53), P=0.730], sensitivity [93.0% (53/57) VS 90.2% (46/51), P=0.732], specificity [100.0% (6/6) VS 100.0% (2/2), P=1.000], positive predictive value [100.0% (53/53) VS 100.0% (46/46), P=1.000] and negative predictive value [60.0% (6/10) VS 28.6% (2/7), P=0.335] of combined cytology and histology in distinguishing benign and malignant lesions between the two groups. In the FNA group, the diagnostic accuracy of combined cytology and histology was higher than cytology alone [93.7% (59/63) VS 81.0% (51/63), P=0.008], and was higher than histology alone without statistical significance [93.7% (59/63) VS 87.3% (55/63), P=0.125]. In the FNB group, the diagnostic accuracy of combined cytology and histology was higher than cytology alone [90.6% (48/53) VS 69.8% (37/53), P=0.001], but not than histology alone [90.6% (48/53) VS 90.6% (48/53)， P=1.000]. For solid masses located in pancreatic body/tail, the diagnostic accuracy for malignancy by histology using FNB needles tended to be higher than that of FNA needles [100.0% (17/17) VS 81.3% (26/32), P=0.080]. Conclusion:Both FNA needles and FNB needles exhibit adequate diagnostic yield for solid pancreatic masses when combining cytology and histology. FNB needles may offer a higher histological diagnostic yield.

Objective To explore the clinical efficacy of arthroscopy combined with cubital tunnel expansion and plasty in the treatment of patients with elbow osteoarthritis and cubital tunnel syndrome.Methods A total of 101 patients with elbow osteoarthritis and cubital tunnel syndrome who were admitted to the Department of Orthopedics,Cangzhou Hospital of Integrated TCM-WM Hebei from September 2020 to August 2023 were selected as the research subjects.According to different surgical methods,the patients were divided into an observation group(n=51)and a control group(n=50).The surgical method in the observation group was arthroscopy combined with cubital tunnel expansion and plasty,and the surgical method in the control group was conventional cubital tunnel expansion and plasty.The operation time,intraoperative blood loss,length of hospital stay,and complications were observed and recorded for both groups.The mayo elbow performance score(MEPS)was used to assess elbow function,the activities of daily living(ADL)scale was used to evaluate daily living ability,and the visual analogue scale(VAS)was used to assess pain levels preoperatively and at 6 months postoperatively.Elbow range of motion,including pronation,supination,and flexion-extension,was measured using a goniometer.Nerve recovery was evaluated by measuring compound muscle action potential(CMAP)of the abductor digiti minimi,ulnar nerve conduction velocity(NCV),and motor evoked potential latency(MEPLP)using a Keypoint electromyography device.Results The operation time and length of hospital stay in the observation group were significantly shorter than those in the control group,and the intraoperative blood loss and complications were significantly less than those in the control group(P＜0.05).Before operation,there were no statistically significant differences in MEPS scores,ADL scores and VAS scores between the observation group and the control group(P＞0.05);6 months after operation,the MEPS scores and ADL scores of patients in the observation group were signifi-cantly higher than those in the control group,and the VAS scores were significantly lower than those in the control group(P＜0.05).Before operation,there were no statistically significant differences in pronation,supination and flexion-extension between the observation group and the control group(P＞0.05);6 months after operation,the pronation,supination and flexion-extension of patients in the two groups were significantly higher than those before operation(P＜0.05),but there were no statistically significant differences in pronation,supination and flexion-extension between the observation group and the control group(P＞0.05).Before operation,there were no statistically significant differences in CMAP,NCV and MEPLP between the observation group and the control group(P＞0.05);6 months after operation,the CMAP and NCV of patients in the observation group were significantly higher than those in the control group,and the MEPLP ratio was significantly lower than that in the control group(P＜0.05).Conclusion Conventional cubital tunnel expansion and plasty and arthroscopy combined with cubital tunnel expansion and plasty can improve the range of motion of the elbow in patients with elbow osteoar-thritis and cubital tunnel syndrome,but the latter features less damage and faster recovery,is better in improving elbow function and daily living ability,reducing pain,and adjusting electromyographic examination indicators,and has fewer complications.
