In 2022， Hainan provincial government launched the project for the prevention and control of viral hepatitis with the goals of a hepatitis B screening rate of 90%， a diagnostic rate of 90%， and a treatment rate of 80% among people aged 18 years and above by the year 2025， and the main intervention measures include population-based prevention， case screening， antiviral therapy， and health management. As of December 31， 2024， a total of 6.875 million individuals in the general population had been screened for hepatitis B， with a screening rate of 95.6%. A total of 184 710 individuals with positive HBsAg were identified， among whom 156 772 were diagnosed through serological reexamination， resulting in a diagnostic rate of 84.9%. A total of 50 742 patients with chronic hepatitis B were identified， among whom 42 921 had hepatitis B-specific health records established for health management， with a file establishment rate of 84.6%. A total of 31 553 individuals received antiviral therapy， with a treatment rate of 62.2%. A total of 2.503 million individuals at a high risk of hepatitis C were screened， among whom 4 870 tested positive for HCV antibody and 3 858 underwent HCV RNA testing， resulting in a diagnostic rate of 79.2%， and 1 824 individuals with positive HCV RNA were identified， among whom 1 194 received antiviral therapy， with a treatment rate of 65.5%. In addition， 159 301 individuals with negative HBsAg and anti-HBs and an age of 20 — 40 years were inoculated with hepatitis B vaccine free of charge. Through the implementation of the project for the prevention and control of viral hepatitis， a large number of hepatitis patients have been identified， treated， and managed in the province within a short period of time， which significantly accelerates the efforts to eliminate the crisis of viral hepatitis.

To investigate the mechanism of Qitu Erzhi Decoction(QTEZ) in ameliorating chemotherapy-induced myelosuppression and the focus of its decomposed formulae on the effects of hematopoietic cells of the three lineages, respectively. Ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS) was used to identify the components of QTEZ intestinal absorption liquid and obtain the target sites, which were intersected with chemotherapy-induced myelosuppression targets collected from several databases, including OMIM, and an interaction network was established based on network pharmacology for Gene Ontology(GO) functional analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis. Hematopoietic stem cells of mice were taken after intraperitoneal injection of 5-fluorouracil for myelosuppression modeling and randomly divided into the model group, Qitu Erzhi group, Astragali Radix-Angelicae Sinensis Radix group, Ligustri Lucidi Fructus-Ecliptae Herba group, Psoraleae Fructus-Cuscutae Semen group, and positive drug group, which were given the corresponding traditional Chinese medicine intestinal absorption liquid and the positive drug granulocyte colony-stimulating factor, respectively. The normal hematopoietic stem cells were taken as the control group and were given the intervention of normal saline. The proliferation of hematopoietic progenitor cells of three lineages was observed by flow cytometry, and the cell cycle and colony formation assay were observed. Western blot was used to verify the effect of QTEZ on the pathway proteins including phosphoinositide 3-kinase(PI3K), phosphorylated PI3K(p-PI3K), protein kinase B(AKT), and phosphorylated AKT(p-AKT). RT-qPCR and Western blot were used to detect the effects of QTEZ on cell cycle-related targets such as CDK inhibitor 1(P21), cyclin D1(CCND1), and cyclin-dependent kinase 4(CDK4). The results showed that a total of 158 components were identified by QTEZ, and 375 component and disease intersecting targets were obtained, 21 core components and 40 core targets were obtained after constructing the network, and GO and KEGG enrichment showed signaling pathways such as PI3K/AKT. QTEZ and its decomposed formulae could promote the 5-fluorouracil-blocked cell cycle to resume operation, and all of them had different degrees of restoration effects on the set of colonies, among which QTEZ had the best restoration effect, and the Astragali Radix-Angelicae Sinensis Radix group had a focused effect on colony forming unit-erythrocyte. Western blot results indicated that there was no significant difference in the expression levels of pathway proteins among the groups. RT-qPCR and Western blot results showed that QTEZ could down-regulate P21 and up-regulate the protein and mRNA expression of CDK4 and CCND1. In conclusion, QTEZ and its decomposed formulas can exert a protective effect on hematopoietic stem cells with 5-fluorouracil-induced myelosuppression by promoting the normal operation of the cell cycle and colony formation, and the mechanism may be related to the down-regulation of the cell cycle-related targets of P21 and the up-regulation of CDK4 and CCND1. In addition, Astragali Radix-Angelicae Sinensis Radix can have a targeted protective effect on erythrocytes.

OBJECTIVE: This study aimed to identify high-risk areas for type 2 diabetes mellitus (T2DM) mortality to provide relevant evidence for interventions in emerging economies. METHODS: Empirical Bayesian Kriging and a discrete Poisson space-time scan statistic were applied to identify the spatiotemporal clusters of T2DM mortality. The relationships between economic factors, air pollutants, and the mortality risk of T2DM were assessed using regression analysis and the Poisson Log-linear Model. RESULTS: A coastal district in East Guangdong, China, had the highest risk (Relative Risk [RR] = 4.58, P < 0.01), followed by the 10 coastal districts/counties in West Guangdong, China (RR = 2.88, P < 0.01). The coastal county in the Pearl River Delta, China (RR = 2.24, P < 0.01), had the third-highest risk. The remaining risk areas were two coastal counties in East Guangdong, 16 districts/counties in the Pearl River Delta, and two counties in North Guangdong, China. Mortality due to T2DM was associated with gross domestic product per capita (GDP per capita). In pilot assessments, T2DM mortality was significantly associated with carbon monoxide. CONCLUSION High mortality from T2DM occurred in the coastal areas of East and West Guangdong, especially where the economy was progressing towards the upper middle-income level.

AIM:To investigate the relationship between the dynamic changes of Lymphocyte-to-monocytes ratios(LMR)before PD-1 inhibitor treat-ment and the efficacy and prognosis of PD-1 inhibi-tor treatment in patients with advanced non-small cell lung cancer(NSCLC).METHODS:The clinical case data of 83 patients with advanced non-small cell lung cancer admitted to the Cancer Hospital of Wuhu Second People's Hospital from June 2019 to July 2022 were retrospectively analyzed.The rou-tine blood LMR values of all patients before and af-ter treatment were collected,the cut-off value was calculated according to the ROC curve,and the LMR was divided into two groups:high and low be-fore treatment and after treatment.The differenc-es of ORR,DCR,PFS and OS among the patients in each group were analyzed and compared,and the value of LMR value and dynamic changes after treatment on the efficacy and prognosis of patients with PD-1 inhibitors in the treatment of NSCLC pa-tients was analyzed.RESULTS:According to the ROC curve,the critical value of LMR was 1.8,and the LMR was divided into the low LMR group at baseline(LMRB/S<1.8),the high LMR group at base-line(LMRB/S≥1.8)and the low LMR group after treatment(LMRafter<1.8)and the high LMR group af-ter treatment(LMRafter≥1.8).The ORR and DCR after immunotherapy in the high LMRB/S group were high-er than those in the low LMRB/S group(P=0.037;P= 0.0025).Among the patients with low LMRB/S be-fore treatment,the DCR of the LMRafter≥1.8 group was better than that of the LMRafter<1.8 group after treatment(P=0.005).Among the patients with high LMR before treatment,the DCR of the LMRafter≥1.8 group was better than that of the LMRafter<1.8 group(P=0.034).Kaplan-Meier analysis showed that PFS and OS were longer in the high LMRB/S group than in the low LMRB/S group before treat-ment.In the low LMRB/S group before treatment,PFS and OS were longer in patients with LMRafter≥1.8 than those with LMRafter<1.8(P=0.047;P=0.007).Multivariate Cox regression model analysis showed that high LMRB/S value before treatment was an in-dependent risk factor for PFS and OS in NSCLC pa-tients(P=0.006;P=0.033).CONCLUSION:High LMR value of patients before immunotherapy may im-prove the efficacy of PD-1 inhibitors,improve the prognosis of patients,and prolong the survival time.Moreover,the increase of LMR value after treatment may increase the efficacy of patients with low LMR before treatment and improve the prognosis of patients.

Objective:To explore the mechanism of miR-30e-5p inhibiting the invasion and migration of hepatoma cells by targeting phosphoinositide-3-kinase catalytic delta polypeptide(PIK3CD)-mediated phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)/mammalian target of the rapamycin(mTOR)signaling pathway.Methods:HepG2 cells were divided into control group,miR-30e-5p mimics group,PIK3CD knockdown group,negative control group,and miR-30e-5p mimics+PIK3CD overexpression group by transfecting the corresponding plasmids,the expression of miR-30e-5p,PIK3CD and PI3K/AKT/mTOR signaling pathway was detected by qRT-PCR and Western blot;the proliferation rate of Hep G2 cells in each group was detected by CCK-8 method;cell migration and invasion were measured by cell scratch test and Transwell test;the expression of matrix metalloproteinase(MMP)2,MMP9,E-cadherin,N-cadherin,Vimentin in Hep G2 cells of each group were detected by Western blot.The targeting regulation of miR-30e-5p on PIK3CD in Hep G2 cells was detected by double luciferase report assay.Results:Compared with the control group,the proliferation rate,migration rate,invasion number,the expression of N-cadherin,MMP2 and MMP9 proteins,the expression of PIK3CD protein and mRNA,p-P13K/PI3K,p-AKT/AKT,and p-mTOR/mTOR in the miR-30e-5p mimics group and PIK3CD knockdown group were lower(P＜0.05),the expression of E-cadherin protein was higher(P＜0.05).Overexpression of PIK3CD attenuates the inhibitory effects of miR-30e-5p mimics on proliferation,migration and invasion of hepatocellular carcinoma cells and elevates the expression of PI3K/AKT/mTOR pathway-related proteins;miR-30e-5p targets down-regulation of PIK3CD expression.Conclusion:Up-regulation of miR-30e-5p can prevent PI3K/AKT/mTOR signal activation by decreasing the expression of PIK3CD,thereby inhibiting the proliferation,migration and invasion of hepatocellular carcinoma cells.

Gallbladder carcinoma,a relatively rare malignancy within the biliary tract,presents a grave prognosis primarily due to asymptomatic early stages leading to advanced stage diagnosis and the absence of efficacious treatment options.Research has identified chronic inflammation,predom-inantly caused by gallstones,as a critical etiological factor.While surgical intervention offers potential curative outcomes in early stages,the majority of cases are identified too late for optimal surgical outcomes.Chemotherapy and targeted therapy,despite offering new therapeutic avenues,have not significantly improved overall survival rates.Thus,understanding the pathogenesis of gallbladder cancer,especially its association with key genetic and molecular pathways,is imperative for devising novel therapeutic strategies.This review delineates the epidemiology,pathogenesis,current treat-ment modalities,and research advancements in gallbladder cancer,aiming to provide innovative in-sights for clinical management and guide future research endeavors.

Objective To investigate the effectiveness and safety of acetaminophen combined with ketorolac tromethamine in pain management early after laparoscopic cholecystectomy(LC).Methods Ninety patients with LC under general anesthesia,42 males and 48 females,aged 18-78 years,BMI 18-28 kg/m2,ASA physical statusⅠorⅡ,were selected and randomly divided into two groups by random num-ber table method:the acetaminophen combined with ketorolac tromethamine group(group AK)and the nal-buphine group(group NA),45 patients in each group.Group AK received 500 mg(diluted to 50 ml)of acetaminophen injection and 30 mg of ketorolac tromethamine(diluted to 10 ml)injection pumped 15 mi-nutes before induction of anesthesia,and group NA received 50 ml of NS injection and 0.2 mg/kg of nalbu-phine(diluted to 10 ml)injection pumped at the same time.Postoperative pain was recorded 0.5,3,6,12,and 24 hours after surgery using VAS pain scores(the non-inferiority boundary Δ = 1.0 score).The sleep quality score on the night of surgery,the number of remedial analgesia cases within 24 hours after sur-gery,the Ramsay sedation score 0.5,3,and 6 hours after surgery,the occurrence of adverse reactions such as nausea and vomiting within 24 hours after surgery,and the overall satisfaction of patients were recorded.Results Compared with group NA,the VAS pain scores 0.5 hour after surgery was reduced in group AK(P＜0.05).The sleep quality score and overall satisfaction in group AK were significantly higher than those in group NA(P＜0.05).There were no significant differences in the rate of remedial analgesia,the score of Ramsay sedation at different time points and the incidence of nausea and vomiting within 24 hours after surgery between the two groups.Conclusion Acetaminophen combined with ketorolac tromethamine is not less effective than nalbuphine in relieving early postoperative pain after laparoscopic cholecystectomy without increasing the incidence of nausea and vomiting.Patients receiving acetaminophen combined with ketorolac tromethamine have higher sleep quality scores on the night of surgery and overall satisfaction.
