This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

ObjectiveTo investigate the trend and influencing factors of newly reported human immunodeficiency virus (HIV) positivity rate among men who had sex with men (MSM) in Shanghai from 2021 to 2024, and to provide evidence for formulating scientific prevention and control measures of AIDS. MethodsMultiple rounds of cross-sectional questionnaire surveys were conducted among MSM by Shanghai Qing’ai Health Promotion Center. Pearson and Cochran-Armitage trend χ² tests were used to analyze the differences and changes in population characteristics and newly reported HIV positivity rates. A logistic regression model was applied for multivariate analyses of factors associated with newly reported HIV positivity. ResultsA total of 1 653 MSM who had not been previously diagnosed with HIV infection were surveyed. The newly reported HIV positivity rates in 2021, 2023, and 2024 were 7.87%, 3.91%, and 3.06%, respectively, showing a decreasing trend (χ²_trend=13.460, P_trend<0.001). Multivariate analyses revealed that MSM aged 18‒<25 years, residing locally for <1 year, identifying as bisexual, lacking HIV knowledge, and having ≥10 same-sex partners in the past 6 months exhibited higher newly reported HIV positivity rates. Conversely, MSM knowledgeable about HIV prevention, residing locally for 1‒5 years, and engaging in oral sex with male partners in the past 6 months demonstrated lower HIV positivity rates. Annual analyses revealed that MSM with HIV knowledge had lower newly reported HIV positivity rates in 2023 and 2024 (aOR=0.300, 95%CI: 0.811‒0.111; aOR=0.202, 95%CI: 0.085‒0.483). ConclusionThe newly reported HIV positivity rate among MSM in Shanghai from 2021 to 2024 showed a decline. Future interventions should focus on young and mobile MSM, strengthen HIV knowledge education through platforms such as the internet, promote safe sexual behaviors and regular testing, and further expand the coverage of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) to control HIV transmission within this population.

Objective: To investigate the status of regular HIV testing and post exposure prophylaxis (PEP) behaviors among men who have sex with men (MSM) in Lishui City, Zhejiang Province, so as to provide the reference for developing targeted intervention strategies. Methods: A total of 389 MSM were selected from Lishui City by convenient sampling method from April to August 2022, and demographic information, sexual behaviors, HIV testing and PEP behaviors were collected through questionnaire surveys. MSM were clustered using two step clustering analysis, and regular HIV testing and PEP behaviors among different groups of MSM were compared. Factors affecting regular HIV testing and PEP behaviors were evaluated using a multivariable logistic regression model. Results: The MSM surveyed had a median age of 31.00 (interquartile range, 16.00) years. There were 146 MSM undergoing regular HIV testing, accounting for 37.53%, and 47 MSM receiving PEP, accounting for 12.08%. MSM were divided into two groups. There were 28.05% of MSM with regular HIV testing in group 1, which was lower than the 44.44% in group 2; and 22.56% receiving PEP, which was higher than the 4.44% in group 2 (both P<0.05). Multivariable logistic regression analysis identified age (OR=1.030, 95%CI: 1.011-1.050), sexual roles (both receptive and insertive, OR=2.999, 95%CI: 1.732-5.194) and homosexual behaviors in the past 6 months (use condoms every time, OR=4.567, 95%CI: 2.593-8.044) as factors affecting regular HIV testing among MSM; age (OR=0.970, 95%CI: 0.942-0.999), sexual orientation (OR=0.292, 95%CI: 0.139-0.612) and homosexual behaviors in the past 6 months (not use condoms, OR=0.135, 95%CI: 0.040-0.460; use condoms every time, OR=0.076, 95%CI: 0.018-0.326) as factors affecting PEP behaviors among MSM. Conclusion MSM with different characteristics of sexual behaviors have different preferences for HIV regular testing and PEP, with homosexual behaviors in the past 6 months, sexual roles and sexual orientation being the main influencing factors.

Objective:To establish the ultra high performance liquid chromatography (UPLC) fingerprints of Mume flos at different flowering stages; To provide reference for the quality research of Mume flos.Methods:The fingerprints of Mume flos were established by UPLC method, and the common peaks were identified by high performance liquid chromatography high resolution mass spectrometry (LC-MS). Chemometrics analysis was carried out with the fingerprints' common peak area of plum blossom at different flowering stages as a variable. Semiquantitative analysis of changes in flavonoids and phenolic acids in Mume flos at different flowering stages was conduct using peak area calculation method.Results:Totally 31 common peaks were identified in the fingerprints of plum blossom medicinal materials at different flowering stages and 9 components were identified. Clustering analysis (HCA) and principal component analysis (PCA) both classified plum blossom medicinal herbs at different flowering stages into three categories. Among them, there were significant differences between the groups at the bud stage, blooming period, and final flowering period, while the differences between the groups at blooming period and final flowering period were relatively small. The orthogonal partial least squares discriminant analysis (OPLS-DA) screened 16 different components with VIP>1.0. The contents of phenolic acids in different flowering stages were as follows: bud stage>blooming period>final flowering period, while the contents of flavonoids were as follows: blooming period>final flowering period>bud stage.Conclusions:This method is simple and reliable, and can provide reference for the quality evaluation of plum blossom medicinal materials at different flowering stages.

ObjectiveTo analyze the clinical and epidemiological characteristics of confirmed cases of human monkeypox infection in Changning District， Shanghai， and to explore their clinical and epidemiological characteristics. MethodsClinical data from 10 reported cases of monkeypox in individuals residing in Changning District or identified by local medical institutions between July 20 and September 30， 2023， were collected. Epidemiological case investigations were conducted， and throat swabs， anal swabs， and rash swabs were collected by the treating medical institutions. Real-time fluorescence quantitative PCR was used for monkeypox virus nucleic acid testing， and descriptive epidemiological analysis was applied to analyze the epidemiological characteristics of the cases. ResultsAll 10 confirmed cases of human monkeypox infection were all young males with an average age of 35.4 years， all of whom belonged to the men who have sex with men （MSM） population， with no occupational clustering. The primary clinical symptoms included fever， rash， enlarged inguinal lymph nodes， and muscle soreness. Nine cases presented with a rash， and seven cases experienced fever symptoms. Among the 10 cases， one experienced fever， rash， enlarged lymph nodes， and muscle soreness； two had fever， rash， and enlarged lymph nodes； two had fever， rash， and systemic soreness； two had only a rash； one had fever or rash； and one was asymptomatic. Among the nine cases with a rash， the rash was mainly localized to the genital or anal area， with fewer cases presenting rashes on the limbs or trunk simultaneously. All cases reported a history of non-exclusive MSM behavior within 21 days before the onset of the disease. The interval between the last suspected high-risk exposure and the onset of symptoms was 4 to 10 days， with an average interval of 6.9 days. The time from the onset of fever to the appearance of a rash was 0 to 5 days， with an average of 1.87 days. ConclusionThe main clinical manifestations of human infection with monkeypox are fever， rash， and enlarged inguinal lymph nodes. The MSM population is a high-risk group for monkeypox infection， and its source of infection may be associated with MSM exposure. Early-stage symptoms are mild， leading to potential underdiagnosis. Additionally， patients may conceal information during the investigation process， which increases the difficulty of epidemic prevention and control.

AIM:To observe the efficacy and safe-ty of combined lipid-lowering strategies in the ini-tial stage of treatment in"very high-risk ASCVD"pa-tients in cardiology outpatient clinics in a real-world prospective cohort study.METHODS:Pa-tients with"very high-risk ASCVD"from January to June 2021 were consecutively enrolled and divided into three groups according to the actual lipid-low-ering treatment strategies:Atorvastatin group;Atorvastatin combine with ezetimibe group;Atorv-astatin combine with evolocumab group.The pri-mary observation endpoints were the changes in LDL-C,Lp(a),and non-HDL-C after one month of treatment,and the secondary endpoints were the changes in TC,TG,HDL-C,Hs-CRP,and safety indica-tors.RESULTS:The efficacy of the combined lipid-lowering strategy in the initial stage of treatment was significantly better than that of the Atorvas-tatin group:LDL-C,Log[Lp(a)],non-HDL-C,TC sig-nificantly decreased(all P＜0.05).Compared with the Atorvastatin combine with Ezetimibe group,LDL-C and Log[Lp(a)]decreased significantly in the Atorvastatin combine with Evolocumab group(P＜0.05),and TC and TG had decreased insignifi-cantly(P＞0.05).When"LDL-C＜1.4mmol/L or＜1.8 mmol/L"is used as the standard for lipid-low-ering compliance,the LDL-C compliance rates of the two groups of combined lipid-lowering treat-ments are higher than those of the atorvastatin sin-gle-drug group.The differences were all statistically significant(all P＜0.05);the LDL-C compliance rate of the atorvastatin combined with evolocumab group was higher than that of the atorvastatin com-bined with ezetimibe group,and the differences were statistically significant(All P＜0.05).When the reduction rate of"LDL dropped by more than 50％"alone or in combination were used as the standard,no one in the three groups could reach the stan-dard.The liver aminotransferase levels had no signif-icant changes among the 3 groups after treatment(all P＞0.05).Myocardial enzyme isoenzyme(CK-MB)decreased among the 3 groups insignificantly(P＞0.05).Compared with the Atorvastatin group,the blood sugar(BS)of the two combined lipid-low-ering groups decreased significantly(P＜0.05);The BS of the Atorvastatin+ezetimibe group significant-ly decreased than that of Atorvastatin combine with Evolocumab group(P＜0.05).CONCLUSION:The lipid-lowering effect and LDL-C compliance rate of patients with"very high-risk ASCVD"in the cardi-ology outpatient department after 1 month of com-bined lipid-lowering treatment were better than those of the atorvastatin monotherapy group.When LDL-C＜1.4 mmol/L or＜1.8 mmol/L is the lip-id-lowering target,the LDL-C compliance rate after 1 month of treatment in the atorvastatin combined with evolocumab group is higher than that of the combined atorvastatin and zetamibu group.When the"LDL drop by more than 50％"is used as the standard for lipid lowering,it is difficult to reach the standard within 1 month.Outpatient"very high-risk ASCVD"patients were treated with initial combined lipid-lowering therapy for 1 month with-out adverse reactions.The initial combined lipid-lowering strategy can be used for patients with"very high-risk ASCVD"in cardiology outpatient clinics who need to achieve LDL-C values early.Atorvastatin combined with evolocumab strategy can be recommended for those patients who re-quire LDL-C＜1.4 mmol/L or＜1.8 mmol/L within one month.

Nasopharyngeal carcinoma is one of the most common head and neck tumors. At present, intensity modulated radiation therapy (IMRT) is the main radical treatment. In recent years, adaptive radiation therapy (ART) becomes the focus in the research field of precision radiotherapy. ART can reduce the target conformal and dose changes and increase the dose of exposed organs caused by factors such as weight loss, positioning error, systematic error, and anatomical changes of lesions and organs at risk, thus improving the effectiveness and safety of intensity modulated radiotherapy. This article focuses on and summarizes the recent progress in the application of ART in nasopharyngeal carcinoma, and puts forward the possible research direction in the future.

Abstract: Objective To analyze the epidemiological characteristics of human brucellosis in Hebei Province, and to explore strategies and measures for its prevention and control. Methods Data on brucellosis cases reported in Hebei Province were collected from the National Notifiable Infectious Disease Reporting Information System. The total situation of brucellosis was described, and the epidemiological characteristics of brucellosis in Hebei Province were analyzed. The spatial autocorrelation analysis method was used to explore the spatial distribution characteristics of brucellosis incidence at the county level in Hebei Province. Results From 2018 to 2023, a total of 21 718 cases of brucellosis were reported in Hebei Province, with 1 death (in 2021). The annual incidence rate fluctuated between 3.91/100 000 to 6.26/100 000, with an average annual reported incidence rate of 4.84/100 000. The epidemic peak was from April to July, showing obvious seasonal characteristics. The incidence in males was higher than in females, with a male-to-female ratio of 2.81∶1. The incidence age was concentrated 30-<70 years, accounting for 85.33% of the total cases. The primary occupational group affected was farmers, accounting for 88.59%. The top three cities with the highest average annual incidence rate were Zhangjiakou, Chengde, and Hengshui, which reported a total of 7 801 cases, representing 35.92% of the total cases in the province. From the perspective of spatial distribution: the global spatial autocorrelation analysis showed clustering distribution in Hebei Province from 2018 to 2023, and there were hot spots in local spatial autocorrelation analysis. The high-incidence areas of brucellosis were mainly concentrated in Zhangjiakou (13.651 3/100 000) and Chengde (13.116 7/100 000) in the north of Hebei Province during the past six years. The "low-low" clustering areas were mainly distributed in Tangshan, Shijiazhuang, and Handan. The "low-high" clustering areas were mainly located around the "high-high" cluster areas, in some counties of Zhangjiakou and Chengde. Conclusions The situation of human brucellosis prevention and control in Hebei Province remains challenging. It is recommended to strengthen the management of infection sources, enhance the surveillance of human brucellosis, focus on health education and behavior intervention in high-risk groups, and intensify prevention and control efforts in the hotspot areas.

Objective:To design a method to introduce random six-dimensional setup error (6D-SE) into the intensity-modulated radiotherapy (IMRT) planning for rectal cancer and evaluate its dosimetric effect.Methods:A total of 21 IMRT plans for patients with rectal cancer were randomly selected as reference plans [2 Gy per fraction for a total of 50 Gy; a 5 mm uniform margin around the clinical target volume (CTV) was taken as the planning target volume (PTV)]. For each fraction of the reference plan, a randomly generated 6D-SE was introduced by adjusting the geometrical parameters of the radiation field, and the dose was recalculated. The overall dose distribution with 6D-SE was obtained by adding up the dose of each fraction. A treatment simulation program that could complete the above workflow was developed using the Varian Eclipse scripting API (ESAPI). 6D-SEs that obey two preset distributions [distribution 1: translational error obey N(0, 4 2), and rotational error obey N(0, 2 2); distribution 2: translational error obey N(0, 2 2), and rotational error obey N(0, 1 2)] were introduced into the reference plans, and the dosimetric effects were assessed. Results:When the reference plans, error distribution 1, and error distribution 2 were applied, the Dmin values of the CTV were (49.4±0.41), (47.56±0.76), and (49.17±0.64) Gy, respectively; the D98% values of the CTV were (50.23±0.07), (49.98±0.10), and (50.27±0.09) Gy, respectively; the D98% values of the primary target area (the kernel part of the target area, excluding the margins) were (50.25±0.08), (50.42±0.13), and (50.33±0.10) Gy, respectively; the D98% values of the marginal area were (50.22±0.10), (49.88±0.11), and (50.26±0.10) Gy, respectively. In addition, compared with the result of the reference plans, the result of errors 1 and 2 showed no significant changes in the mean dose of the bladder and femoral heads ( P>0.05), despite slight decreases in the conformity index of the dose distribution with limited clinical significance. Conclusion:The proposed method and the treatment simulation program developed thereupon can introduce the 6D-SE obeying different distributions into the IMRT plans for rectal cancer on demand and provide overall dosimetric changes.
