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.

ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions， so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values（L^*） of the surface， cross-section and powder of the samples， texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography（HPLC） was used to determine the contents of seven nucleoside components（uracil， hypoxanthine， uridine， inosine， guanosine， β-thymidine and adenosine） in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis（PCA） was used to comprehensively rank the data of various indicators， and partial least squares-discriminant analysis（PLS-DA） was used to screen differential components with variable importance in the projection（VIP） value>1. Furthermore， the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature， the color of the intermittently dried samples gradually deepened， while their hardness gradually decreased. Concurrently， the contents of extract， total starch， uridine and adenosine exhibited an upward trend， whereas the contents of uracil， hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group， the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose， the hardness and the total content of nucleoside components in the samples showed a downward trend， while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L^* was negatively correlated with the contents of uracil， hypoxanthine and inosine， and positively correlated with the contents of uridine， guanosine and adenosine. Hardness was negatively correlated with adenosine content， and positively correlated with the contents of inosine， uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components， the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract， the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition， while uridine， uracil， guanosine， adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination， which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

Objective To investigate the causes of abnormal decrease in maximum amplitude(MA)of thromboelastog-raphy(TEG)and its effect on prognosis by monitoring the changes of coagulation-related indexes in emergency trauma pa-tients.Methods A total of 319 cases of trauma patients admitted to our hospital from September 2020 to September 2023 were retrospectively analyzed,and the coagulation-related indexes of 0 h and 24 h after admission were observed.According to the MA results,they were divided into normal MA group(>50 mm)and reduced MA group(≤50 mm)to compare the hemoglobin(Hb),platelets count(Plt),activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(Fib),thrombin time(TT),D-dimer(D-D),coagulation reaction time(R),clot formation kinetics(Angle),30 min clot dissolution rate(Ly30),MA,thrombine-antithrombin complex(TAT)and plasminase-α2 plasminase inhibitor complex(PIC).The correlation between MA and fibrinolysis indexes in 319 trauma patients was analyzed.According to whether tranexamic acid(TXA)was used,the reduced MA group was divided into a TXA group and a non-drug group.The differ-ences in the change of the above coagulation-related indexes,mortality rate and changes in blood product dosage were com-pared between the two groups.Results Compared with the normal MA group,Hb,Plt,Fib,diastolic blood pressure and GCS scores decreased,while heart rate,ISS score and mortality increased significantly in the reduced MA group(P<0.05).The R,PT and TT were prolonged significantly(P<0.05),and PIC and D-D increased significantly(P<0.05)in the re-duced MA group.Correlation analysis found that MA had no correlation with Ly30,TAT and APTT,but was correlated with Angle(r=0.803),Plt(r=0.544),Fib(r=0.581),PIC(r=-0.443)and D-D(r=-0.343).Compared with the non-drug group,the change of Angle,MA and FIB in the TXA group increased significantly(P<0.05),while the change of PIC de-creased(P<0.05).Cryoprecipitate and platelet transfusion in the TXA group reduced significantly(P<0.05),and red blood cell transfusion had a decreasing trend,but the difference was not significant(P>0.05).The mortality rate in the TXA group was reduced significantly(P<0.05).Conclusion Hyperfibrinolysis may be an important factor in the abnormal decrease of MA in emergency trauma patients.Treatment with TXA can improve its effect on MA,and reduce the transfusion of blood products and the patient mortality.

In this paper， by consulting the historical herbs and medical classics coupled with related literature in modern research， the historical edition of Chinese Pharmacopoeia and local chronicles of traditional Chinese medicine （TCM） along with the ancient historical evolution of the processing methods of Pinelliae Rhizoma origin as well as the related processing methods of Pinelliae Rhizoma origin from 1959 to 2020 were systematically collated and summarized. It was found that the main processing methods of Pinelliae Rhizoma origin were peeling， decoction washing， lime wrapping and sun-drying. However， stacking， peeling， sun-drying or oven-drying are the primary methods in modern local chronicles of TCM. Meanwhile， washing， peeling， removing fibrous roots and sun-drying are the main methods in Chinese Pharmacopoeia. In addition， there were some changes in the quality evaluation of Pinelliae Rhizoma in different historical periods. Round and white were the best in the quality evaluation of Pinelliae Rhizoma in ancient times， while the evaluation indexes were further refined to size， color， texture， powder property， purity and evenness in modern herbal works. In modern studies， the quality of Pinelliae Rhizoma was mostly evaluated by the chemical components such as alkaloids， total organic acids， polysaccharides， nucleosides， fingerprint and pharmacodynamics. At present， the purification and drying stages of Pinelliae Rhizoma are in the transitional stage between the traditional manual peeling and natural drying methods as well as the modern mechanized and large-scale production. Therefore， a reasonable and feasible modern processing methods and guiding standards of Pinelliae Rhizoma are developed urgently to normalize the processing of Pinelliae Rhizoma and ensure the quality of medicinal materials.

Alfalfa(Medicago sativa L.)is the most important legume forage crop worldwide with high nutritional value and yield.For a long time,the breeding of alfalfa was hampered by lacking reliable information on the autotetraploid genome and molecular markers linked to important agro-nomic traits.We herein reported the de novo assembly of the allele-aware chromosome-level genome of Zhongmu-4,a cultivar widely cultivated in China,and a comprehensive database of genomic variations based on resequencing of 220 germplasms.Approximate 2.74 Gb contigs(N50 of 2.06 Mb),accounting for 88.39％of the estimated genome,were assembled,and 2.56 Gb contigs were anchored to 32 pseudo-chromosomes.A total of 34,922 allelic genes were identified from the allele-aware genome.We observed the expansion of gene families,especially those related to the nitrogen metabolism,and the increase of repetitive elements including transposable elements,which probably resulted in the increase of Zhongmu-4 genome compared with Medicago truncatula.Population structure analysis revealed that the accessions from Asia and South America had rela-tively lower genetic diversity than those from Europe,suggesting that geography may influence alfalfa genetic divergence during local adaption.Genome-wide association studies identified 101 sin-gle nucleotide polymorphisms(SNPs)associated with 27 agronomic traits.Two candidate genes were predicted to be correlated with fall dormancy and salt response.We believe that the allele-aware chromosome-level genome sequence of Zhongmu-4 combined with the resequencing data of the diverse alfalfa germplasms will facilitate genetic research and genomics-assisted breeding in variety improvement of alfalfa.

Objective:To study the clinical efficacy of 3D total hip arthroplasty in elderly patients with acetabular fracture.Methods:A total of 43 patients with non-obsolete acetabular fractures admitted to Xining First People's Hospital from May 2016 to December 2018 were randomly divided into the control group (22 cases) and the observation group (21 cases) for a perspective study. The control group received routine surgery and the observation group was treated with total hip arthroplasty combined with 3D printing. The patient's operation time, intraoperative blood loss, and hospitalization time were recorded. The hip function was assessed by Harris Hip Scale (HHS) after 6 months of follow-up. The patient's quality of life was assessed using the short form 36 item health survey questionnaire (SF-36) before and 6 months after surgery. The complications of the patients during operation and follow-up were recorded.Results:The operation time, hospital stay and intraoperative blood loss were significantly lower in the observation group than those in the control group ( P<0.05). At 6 months after operation, the hip joint function of the observation group was significantly better than that of the control group ( P<0.05); the quality of life scores were significantly higher than the control group ( P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P<0.05). Conclusions:3D printed total hip arthroplasty can effectively improve the operation and hip function of elderly patients with non-obsolete acetabular fracture and the quality of life of patients without increasing adverse reactions.

In the past, hernia and abdominal wall surgery has been ignored, which may endanger the life of patients due to untimely treatment. In 1997, the concept of tension-free hernia repair was introduced to China. Chinese hernia and abdominal wall surgery entered a new era and developed rapidly. In 2015, scholars in China decided to create our own Hernia Registry. In 2017, Hernia Registry was officially released, and the Chinese Hernia Surgery Alliance was established in the same period. The Chinese Hernia Registry has became the second largest Hernia clinical registry database in the world. Although the follow-up rate needs to be improved, it is possible to have a preliminary understanding and analysis of the incidence of hernia disease in China. There are many difficulties in its application, and it requires the multi-level coordination and long-term commitment. The authors hope that through this work, the diagnosis and treatment of hernia and abdominal wall can be improved, and the ability of communication and cooperation at home and abroad will be enhanced, benefiting the general population of hernia patients.

Objective: To analyze Internet behaviors of children and adolescents and their influencing factors, and to provide scientific basis for health education guidance and prevention measures. Methods: A stratified cluster sampling method was used. From January to June 2019, 30 955 primary school students in 16 provinces (municipalities), from eastern, central, and western economic zones of China were selected to conduct a questionnaire survey, regarding general demographics, diet and exercise, tobacco, alcohol and sleep, Internet and electronics usage, etc. Results: Among them, 43.1% of students had never been online with girls (44.7%) higher than boys (41.8%)(χ2=21.04, P<0.01); 1.3% of students reported online time for more than 4 hours a day, boys were significantly higher than girls(χ2=15.87, P<0.01); Internet addiction was detected in 2.4% of elementary school students, with boys (3.0%) higher than girls(1.7%)(χ2=331.77, P<0.01), and the trend increases with grade. With sixth grade (3.3%) were significantly higher than children from the first grade (0.8%) and other grades(χ2=163.96, P<0.01). Children’s tendency to Internet addiction was 11.9%, of which boys were 13.0% and girls were 10.6%, boys were significantly higher than girls(χ2=117.66, P<0.01). Pearson correlation analysis revealed that, after controlling gender age, boarding school, family relationship, single parents and regrouped families, smoking, drinking sugary drinks, eating fried foods, and left-behind were positively related to Intenet addiction(r=0.06, 0.07, 0.27, 0.44, 0.07, 0.11, 0.09, P<0.01), while medium and high intensity sports, effective physical education, health education in school, AIDS education and parental restrictions on TV and computer games, were negatively associated with internet addiction(r=-0.74, -0.65, -0.04, -0.05, -0.63, P<0.01). Conclusion The internet addiction of Chinese primary school students is common and increases by year. High-intensity, high-density sports, effective physical education, and health education could help prevent Internet addiction among children.

OBJECTIVE：To study the effects of stilbene glucoside （TSG）on the proliferation and estrogen receptor （ER）of human breast cancer T- 47D cells ，and to explore its estrogen-like effect and potential mechanism. METHODS ：Taking ER positive human breast cancer T- 47D cells as subjects ，using β-estradiol（β-E2，1×10－8 mol/L）as positive control ，CCK-8 assay was used to detect the cell proliferation after treated with different concentrations of TSG （1×10－8，1×10－7，1×10－6，1×10－5，1×10－4 mol/L）for 24，48，72 h；the cell proliferation rate was calculated. Western blotting assay and RT-PCR methods were adopted to detect the protein and mRNA expression of ER-α and ER-β in cells after treated with low，medium and high concentrations of TSG （1×10－8， 1×10－6，1×10－4 mol/L）for 48 h. RESULTS ：After treated with different concentrations of TSG for 24，48，72 h，the cell proliferation rate of each administration group at each time point （except for β-E2 group at 48 h）increased significantly ，compared with blank group ；those of TSG groups （1×10－5，1×10－6，1×10－7 mol/L）were significantly higher than β-E2 group（P＜0.05 or P＜0.01）. After treated with low ，medium and high concentrations of TSG for 48 h，protein and mRNA expression of ER-α and ER-β in cells were increased significantly，compared with blank group （P＜0.05 or P＜0.01）；protein expression of ER-β in TSG low concentration group ，mRNA expression of ER-α in TSG groups as well as mRNA expression of ER-β in TSG low and high concentration groups were significantly higher than β-E2 group（P＜0.05 or P＜0.01）. CONCLUSIONS ：TSG can induce the in vitro proliferation of T- 47D cells and exert estrogen-like effects by promoting protein and mRNA expression of ER-α and ER-β， which is stronger than that of β-E2 at a certain concentration.

Objective:To investigate the specific effect of minimally invasive hard channel intracranial hematoma crush suction flow on patients with cerebral hemorrhage, and to analyze the prognostic factors.Methods:A total of 80 patients with primary intracerebral hemorrhage who were treated in Bengbu First Peopl′s hospital from Aug. 2014 to Aug. 2018 were selected, with 52 males and 28 females, aged from 48 to 81 years and averaged (66.07±13.34) years. The prognosis of patients was assessed using the Bathel Index (BI), and the patients were divided into a control group (BI≥ 60 point considered a good prognosis, n=54) and an experimental group (BI<60 point considered a poor prognosis, n=26). Suspicious prognostic factors were formulated, including gender, age, average drainage time, average puncture needle indwelling time, average hospital stay, Glasgow score, time from injury to operation, bleeding volume, cause of disease, bleeding site, postoperative rebleeding to carry out univariate analysis between groups, and incorporate the difference items in univariate analysis into multivariate logistics regression analysis to explore related prognostic factors were compared by single factor analysis, and the difference items in the single factor analysis were included into the multivariate logistics regression analysis for the related prognostic factors exploring. Results:The hemorrhages was successfully cleared in all patients, and the average drainage time was (5.07±1.25) days. Mean needle retention time was (4.84 ± 1.37) d. Mean length of stay time was (15.26±1.44) days. Allpatients completed follow-up after operation. During 1 year of follow-up, 12 patients showed obvious brain atrophy, subdural broadening and effusion. All patients were followed up for 3 years, and their symptoms completely disappeared and their daily living ability recovered. No death was occured during the follow-up. According to the BI assessment results, the scores of 54 patients were ≥60, with an average score of (74.57±4.36). The scores of 26 patients were <60, with an average score of (48.24±5.12). The age, time from injury to operation and amount of blood loss of control group were significantly lower than those of experiment group, and Glasgow scores were significantly higher than those of experiment group, with statistically significant differences ( P<0.05). The percentage of patients in control group with infratentorial hemorrhage (14.81%) was significantly lower than that in experiment group (34.62%), and the rate of postoperative re-bleeding (1.85%) was significantly lower than that in experiment group (23.08%), with statistically significant differences ( P<0.05). Glasgow score was positively correlated with the prognosis of patients ( OR=3.449, P=0.005). The time from injury to operation was negatively correlated with the prognosis ( OR=0.580, P=0.023). Supratente hemorrhage was a protective factor for patient prognosis ( OR=3.813, P=0.024). Postoperative re-bleeding was correlated with the patients ( OR=19.963, P=0.008). A ROC curve was drawn with Glasgow score and the time from injury to operation. Glasgow score was selected as cut-off point at 7.5 point, with sensitivity of 96.30% and specificity of 88.46%. The time from injury to operation was selected as the cut-off point at 8.35 h, with sensitivity of 84.62% and specificity of 92.59%. Conclusion:Minimally invasive hard channel crush suction flow is effective and safe in the treatment of intracranial hematoma. The severity of cerebral hemorrhage, infratentorial hemorrhage and postoperative re-bleeding are prognostic factors.
