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.

OBJECTIVE: To investigate the predictive value of endothelial activation and stress index (EASIX) for the prognosis of patients with mantle cell lymphoma (MCL). METHODS: A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023, had therapeutic indications and received standard treatment. RESULTS: A total of 66 patients were included and divided into high EASIX group and low EASIX group, according to a cutoff value of 0.97 determined by the receiver operating characteristic (ROC) curve. Multivariate Cox regression analysis showed that prealbumin <0.2 g/L, high EASIX, and ECOG PS score ≥2 were independent risk factors influencing overall survival (OS) in MCL patients. The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months, and the median progression-free survival was 8.8 and 26.0 months, respectively. The proportions of patients with ECOG PS score ≥2 and prealbumin <0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group. CONCLUSION At the time of initial diagnosis, EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL. Furthermore, patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.

Hypercholesterolemia is a significant risk factor for the development of atherosclerosis. 2',3',5'-Tri-O-acetyl-N ⁶-(3-hydroxyphenyl) adenosine (IMM-H007), a novel AMPK agonist, has shown protective effects in metabolic diseases. However, its impact on cholesterol and triglyceride metabolism in hypercholesterolemia remains unclear. In this study, we aimed to elucidate the effects and specific mechanisms by which IMM-H007 regulates cholesterol and triglyceride metabolism. To achieve this goal, we used Apoe ^-/- and Ldlr ^-/- mice to establish a hypercholesterolemia/atherosclerosis model. Additionally, hepatocyte-specific Ampka1/2 knockout mice were subjected to a 5-week high-cholesterol diet to establish hypercholesterolemia, while atherosclerosis was induced via AAV-PCSK9 injection combined with a 16-week high-cholesterol diet. Our results demonstrated that IMM-H007 improved cholesterol and triglyceride metabolism in mice with hypercholesterolemia. Mechanistically, IMM-H007 modulated the AMPKα1/2-LDLR signaling pathway, increasing cholesterol uptake in the liver. Furthermore, IMM-H007 activated the AMPKα1-FXR pathway, promoting the conversion of hepatic cholesterol to bile acids. Additionally, IMM-H007 prevented hepatic steatosis by activating the AMPKα1/2-ATGL pathway. In conclusion, our study suggests that IMM-H007 is a promising therapeutic agent for improving hypercholesterolemia and atherosclerosis through the activation of AMPKα.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

Objective:To investigate the effect of the number of positive preoperative serological tumor markers on the surgical approach and prognosis of patients with intrahepatic cholangiocarcinoma.Methods:This is a retrospective case-series study. Data from 548 patients with intrahepatic cholangiocarcinoma after radical resection from October 2010 to April 2019 were retrospectively collected in 10 hospitals of China. There were 277 males and 271 females with an age of (57.8±10.2)years(range:23 to 84 years). Four hundred and twenty-six patients(77.7%) had at least one positive preoperative serum tumor marker. The data collection included the results of 4 preoperative serological tumor markers,other preoperative indicators(5 prodromal symptoms, 6 medical history,8 preoperative serological indicators,5 preoperative imaging indicators,and 14 preoperative pathological examination indicators),baseline data (gender and age),surgical methods,and prognostic follow-up data. Four preoperative results of serologic tumor marker and surgical procedure were converted into categorical variables. The number of positive preoperative serum tumor markers was used as the treatment variable,the surgical method was used as the mediating variable,and the survival time was used as the outcome variable. Univariate and multivariate analysis were used to screen for other preoperative indicators which were independent factors that influenced the surgical procedure and the prognosis of patients as covariates to analyze the mediating effect.Results:Of the 548 patients included in the study, 176 patients (32.1%) underwent partial hepatectomy,151 patients(27.5%) underwent hemihepatectomy, and 221 patients(40.3%) underwent partial hepatectomy or hemihepatectomy combined with other treatments. The results of the univariate and multivariate analysis showed that the number of positive serum tumor markers,intrahepatic bile duct dilatation,portal vein invasion,pathological differentiation,pathological type,vascular invasion,T stage,N stage and maximum tumor diameter were independent factors influencing the surgical procedure(all P<0.05). Intrahepatic bile duct dilatation,pathological differentiation and T stage were independent prognostic factors for patients with intrahepatic cholangiocarcinoma(all P<0.05). Intrahepatic bile duct dilatation,differentiation and T stage were included as covariates in the mediation effect model. The results showed that the number of positive serum tumor markers before surgery had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.092, P=0.039),and had a positive predictive effect on the surgical method ( β=0.244, P<0.01). The number of positive serum tumor markers had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.151, P=0.002). Direct and indirect effects accounted for 71.3% and 28.7% of total effects,respectively. Conclusions:The higher the positive number of preoperative tumor markers,the worse the prognosis of patients with intrahepatic cholangiocarcinoma. The number of positive cells not only directly affects the prognosis of patients,but also indirectly affects the prognosis of patients by affecting the surgical method.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Objective To discuss the efficacy and safety of transjugular intrahepatic portosystemic shunt(TIPS)for portal hypertension with portal vein thrombosis(PVT).Methods A total of 31 patients with portal hypertension complicated by PVT,who underwent TIPS at the Chinese PLA General Hospital between December 2017 and October 2022,were enrolled in this study.The clinical data,including preoperative laboratory tests,operation pattern,intraoperative portal vein pressure(PVP),postoperative follow-up ultrasound or enhanced CT examination findings,and the presence or absence of hepatic encephalopathy(HE),were collected.Paired t-test was used to compare the differences in PVP before and after stenting,Kaplan-Meier curve was used to analyze the postoperative shunt patency rate,rebleeding rate,incidence of HE,and survival rate.Log-rank test was used to analyze the differences in follow-up results between the patients having cavernous transformation of portal vein(CTPV)and the patients having no CTPV.Results The technical success rate of TIPS procedure was 93.55％(29/31).In the 29 patients with successful surgery,the mean PVP value decreased from preoperative(30.15±4.61)mmHg to postoperative(20.84±5.57)mmHg,the difference was statistically significant(t=8.975,P＜0.05).The postoperative median follow-up time was 22.90 months(range of 4.50-61.80 months).During the follow-up period,24.14％of patients(7/29)developed shunt tract dysfunction,17.24％of patients(5/29)developed rebleeding,17.24％of patients(5/29)developed HE,and 5 patients(5/29,17.24％)died.Ten patients(10/29,34.48％)with PVT were complicated by CTPV,among them 5 patients had shunt dysfunction,3 patients had rebleeding,one patient developed HE,and 3 patients died.Of the 19 patients who having no coexisting CTPV,shunt dysfunction was seen in 2,rebleeding in 2 and HE in 4,and 2 patients died.The incidences of shunt tract dysfunction and rebleeding in the patients having CTPV were obviously higher than those in the patients having no CTPV(both P＜0.05),while no statistically significant differences in the incidences of HE and death existed between the two groups(both P＞0.05).Conclusion TIPS can effectively reduce the PVP in patients with PVT.The incidences of shunt tract dysfunction and rebleeding in the PVP with coexisting CTPV are remarkably higher than those in the PVT patients with no coexisting CTPV.(J Intervent Radiol,2024,33:537-542)

Objective To investigate the effect of continuous intraoperative insulin infusion on my-ocardial blood perfusion after cardiac surgery under cardiopulmonary bypass(CPB).Methods Forty-eight patients,21 males and 27 females,aged 55-80 years,BMI 18-28 kg/m2,ASA physical status Ⅱ-Ⅳ,who underwent elective cardiac surgery with CPB were selected and randomly divided into two groups:the insulin group(group I,n = 25)and the control group(group C,n = 23).The same anesthesia protocol was implemented in both groups.After induction of anesthesia,group Ⅰ received intravenously infusion of in-sulin 30 mU·kg-1·h-1,glucose 0.12 g·kg-1·h-1,and potassium chloride 0.06 mmol·kg-1·h-1,and group C received saline 10 ml/h,all of which were infused until the end of surgery.The targeted blood glucose range for both groups was set at 6.1-11.1 mmol/L.Transesophageal echocardiography(TEE)was performed 10 minutes after induction of general anesthesia(T2)and before the end of surgery(T6)to ex-amine the coronary sinus(CS)flow spectrum and diameter,pulmonary venous flow spectrum,and calculate CS net antegrade flow velocity time integral(VTI).Femoral mean arterial pressure(MAP),central venous pressure(CVP),stroke volume(SV),cardiac index(CI)and peripheral vascular resistance index(SVRI)were recorded at T2,2 minutes before CPB(T3),the end of CPB(T5),and T6.The concentra-tions of blood glucose and lactate 5 minutes before anesthesia induction(T1),T3,30 minutes after CPB(T4),T5,T6,6 hours after surgery(T7),12 hours after surgery(T8),and 24 hours after surgery(T9)were recorded.The levels of high-sensitivity C-reactive protein(hs-CRP),high-sensitivity troponin I(hs-TnI),and creatine kinase isoenzyme(CK-MB)were recorded 1 day preoperatively,1 and 2 days post-operatively.Results Compared with group C,in group I,CS net antegrade flow VTI and blood flow per minute were significantly increased(P<0.05),and pulmonary venous peak atrial reversal wave velocity(ARp)was significantly reduced at T6(P<0.05),SV and CI were significantly increased and SVRI was significantly decreased at T5 and T6(P<0.05),lactate concentration was significantly decreased at T7 and T8(P<0.05),hs-CRP and CKMB were significantly decreased 1 and 2 days postoperatively(P<0.05),hs-TnI was significantly reduced 2 days postoperatively(P<0.05).Conclusion Continuous insulin admin-istration during cardiac surgery with CPB while maintaining blood glucose at 6.1-11.1 mmol/L can enhance myocardial blood perfusion,mitigate postoperative inflammatory response,and reduce myocardial injury.

Crohn's disease(CD)is an autoimmune intestinal disease characterised by chronic and non-specific inflammation,and the exact etiology and pathogenesis are still unclear.Neutrophil gelatinase associated lipocalin(NGAL),a secreted glycoprotein and isolated from neutrophils,is widely involved in pathophysiological processes such as intestinal inflammation response,apoptosis and tumour progression.It has been found that NGAL has the potential to be a clinical biological marker in clinical diagnosis and monitoring of CD activity.Therefore,this paper reviews the application value of NGAL in different clinical samples of CD,in order to provide reference for clinical diagnosis and treatment of CD.
