Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:The aim was to analyze key indicators for the diagnosis and treatment of chronic hepatitis B（CHB），including virus detection rate，standardized treatment rate，and loss to follow-up rate，in order to provide a basis for optimizing diagnosis and treatment plans，improve the diagnosis and treatment level of CHB，and improve patient prognosis.Methods:Patients with CHB admitted to the Guangzhou Eighth People′s Hospital Affiliated to Guangzhou Medical University from January 2024 to January 2025 were enrolled. The datas were collected and organized using Excel. Statistical analysis was conducted using SPSS 26.0 software，with a focus on evaluating core indicators such as virus detection rate，standardized treatment rate，and loss to follow-up rate.Results:The positive rate of hepatitis B surface antigen（HBsAg）in non-specific patients was 28.95%，the antiviral treatment rate in specialized patients was 90.78%，and the standardized antiviral drug conversion treatment rate in low-level viremia（LLV）patients was 61.45%. The standardized antiviral drug conversion treatment rates for high-risk patients with combined kidney/bone injuries were 72.75% and 74.40%，respectively. The overall dropout rate was 10.47%，with a dropout rate of 13.80% for LLV patients.Conclusions:The antiviral treatment coverage rates in CHB patients were over 90%，but in certain groups（such as LLV patients and those with kidney or bone injuries），the standardized treatment rates were still low and loss to follow-up rates were high，suggesting the need to improve HBV screening，treatment for special populations，and patient adherence.

Objective:A novel grass-root community screening and management model of hepatitis B was developed in order to improve the diagnosis and treatment rate of hepatitis B in Guangzhou city.Methods:A three-tier collaborative framework［tertiary hospitals-center for disease control and prevention（CDC）-primary care clinics］implemented dual-track screening（fixed-site+mobile units）using rapid hepatitis B surface antigen（HBsAg）testing and structured surveys. Digital closed-loop management integrated screening，referral，and follow-up. Data were analyzed via SPSS 26.0.Results:Among 30 012 community-dwelling adults screened（Male∶Female=1∶1.68），overall HBsAg positive rate was 5.21%（1 565/30 012），peaking in the 50-59-year cohort（ χ2=271.80， P<0.001）. Hepatitis B knowledge awareness was critically low（39.24%）. Of 140 referred HBsAg-positive individuals，15 chronic carriers required no immediate antiviral therapy per guidelines. Treatment linkage surged from 32.8%（41/125）to 86.4%（108/125）post-intervention. aMAP hepatocellular carcinoma（HCC）risk stratification（n=82）revealed low（36.6%），intermediate（32.9%），and high-risk（30.5%）profiles. Conclusions:This coordinated，digitally-enhanced strategy significantly improved hepatitis B detection and treatment access. However，persistent knowledge gaps underscore the imperative for targeted community education and adherence support.

Objective:To evaluate the effect of preoperative anxiety on the consciousness and autonomic nervous activity during propofol anesthesia.Methods:This study was a secondary analysis of data from the clinical trial in a prospective single-arm study. One hundred and thirty patients, aged 18-65 yr, with a body mass index of 18.5-27.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification I or Ⅱ, scheduled to receive propofol anesthesia, were selected from the Second People′s Hospital of Lianyungang. The six-item of the state anxiety inventory (SAI) of the State-Trait Anxiety Inventory was used to assess the anxiety of patients 1 h before surgery. The patients were divided into 2 groups according to the cut-off value of 12: obvious anxiety symptom (SAI score >12) group (group A, n=49) and no obvious anxiety symptom (SAI score ≤12) group (group B, n=81). After admission to the operating room, the patient was required to hold a 50 ml syringe filled with water. Propofol was given by target-controlled infusion (TCI) with the target plasma concentration set at 5 μg/ml. When the effect-site concentration (Ce) of propofol increased to 3.5 μg/ml (all the patients lost consciousness), the closed-loop TCI was used to maintain BIS value between 45 and 55. The patients were monitored for 20 min after stopping the pump infusion (anesthesia recovery period). The disappearance time of verbal command, disappearance time of eyelash reflex, time of syringe dropping, recovery time of verbal command, recovery time of eyelash reflex, Ce at the recovery of verbal command, Ce at the recovery of eyelash reflex, Ce within the first 5 min of the closed-loop TCI, and consumption of propofol during anesthesia were recorded. The peripheral perfusion index, low frequency power and high frequency power of heart rate variability were recorded, and the ratio of low frequency power to high frequency power was calculated. Pearson correlation analysis was used to assess the correlation between preoperative SAI score and consciousness-related indicators, simulated Ce of propofol and consumption of propofol. Results:Compared with group B, the disappearance time of verbal command, disappearance time of eyelash reflex, and time of syringe dropping were significantly prolonged, the consumption of propofol, simulated Ce at recovery of verbal command and within the first 5 min of closed-loop TCI were increased, the peripheral perfusion index was decreased at each time point before administration and at 14-20 min of anesthesia recovery, and the low-frequency power was decreased during anesthesia maintenance in group A ( P<0.05). The SAI score was positively correlated with the disappearance time of verbal command ( r=0.220, P=0.012), time of syringe dropping ( r=0.206, P=0.029), consumption of propofol ( r=0.330, P<0.001), and the simulated Ce at the recovery of verbal command ( r=0.215, P=0.015) and simulated Ce at recovery of eyelash reflex ( r=0.207, P=0.022). Conclusions:Preoperative anxiety may lead to prolonged loss of consciousness and more marked inhibition of sympathetic nerve activity during propofol anesthesia.

Objective:To investigate the dynamic characteristics of human papillomavirus (HPV) genomic integration during cervical lesion progression and the clinical value of HPV integration detection in stratify HPV-positive women, and to explore its molecular mechanisms in cervical carcinogenesis.Methods:A prospective cohort study was designed to enroll high-risk HPV (HR-HPV) positive women who underwent cervical cancer screening in Drum Tower Hospital Affiliated to Nanjing University Medical School and Nanjing Maternity and Child Health Care Hospital from July 2022 to July 2024. Cervical exfoliated cells samples were collected, and HPV whole genome targeted capture and high-throughput sequencing technology were used. The HPV integration patterns, host gene functional region distribution and pathway enrichment characteristics of 157 samples with different cervical lesions grades were analyzed, including 31 cases of normal cervix, 40 cases of cervical intraepithelial neoplasia (CIN) Ⅰ, 32 cases of CIN Ⅱ, 42 cases of CIN Ⅲ, and 12 cases of cervical cancer.Results:HR-HPV integration was detected in 80.2% (126/157) of the 157 HR-HPV positive samples. The incidence of HR-HPV integration in cervical cancer patients was 12/12, which was higher than that in normal women (77%, 24/31). The incidence of HPV16 integration was significantly higher in high-grade lesions, and the incidence of HPV16 integration was 43% (18/42) in CIN Ⅲ patients and 8/12 in cervical cancer patients ( P<0.001). A total of 14 438 integration events were detected in 126 samples with HPV integration. The integration sites were mainly distributed in the host intergenic region (51.0%, 7 359/14 438) and intronic region (38.1%, 5 494/14 438), and the integration frequency of viral L1 gene was the highest (28.4%, 4 498/16 781). Functional enrichment analysis showed that HPV integration-related host genes were significantly enriched in transport of small molecules,cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG) signaling pathway, and purine ribonucleotide biosynthetic process, which synergistically drove carcinogenesis through multiple mechanisms. Conclusions:HPV integration events are significantly associated with the progression of cervical lesions. HPV integrated detection based on cervical exfoliated cells is expected to optimize the current screening strategy, reduce excessive intervention of HPV positive women and facilitate their accurate triage management.

Objective:To understand the tobacco use situation and related factors among the occupational population in Beijing in 2018.Methods:The data were obtained from a special survey on “Healthy Beijing People—Ten-year Action Plan for Health Promotion (2009—2018)”. From June to September 2018, 12 908 participants were recruited from 16 districts of Beijing using the stratified sampling method combined with the typical sampling method. Questionnaires were conducted to collect basic information, work situations, tobacco exposure in public places, and smoking cessation. The Chi-square test was used to compare the differences in current smoking rates, smoking cessation rates and second-hand smoke exposure rates among participants with different characteristics. Multivariate logistic regression analysis was used to analyze the related factors of tobacco use.Results:The present smoking rate of the occupational population in Beijing was 18.0% (95% CI: 17.3%-18.7%), and the passive smoking exposure rate of non-smokers was 61.0% (95% CI: 60.1%-61.9%). The smoking cessation rate among the working population was 22.2% (95% CI: 20.7%-23.7%), and the proportion of current smokers with the intention to quit was 63.9% (1 485/2 325). The present smoking rate of employees of different genders, ages, education levels and occupational nature showed statistically significant differences ( P<0.05). The results of multivariate logistic regression analysis showed that in males, compared with the age group of 16-29 years old, the risk of smoking increased in the age groups of 30-39 years old, 40-49 years old and over 50 years old [ OR (95% CI) values were 1.49 (1.27-1.74), 1.34 (1.13-1.59) and 1.30 (1.06-1.59)]. Compared with those with junior high school or lower education, participants with high school/vocational/college education group had a higher risk of smoking ( OR=1.38, 95% CI: 1.13-1.69), while those with master′s degree or above had a lower risk of smoking ( OR=0.30, 95% CI: 0.22-0.42). The physical workers ( OR=1.28, 95% CI: 1.11-1.47) had a higher risk of smoking than the mental workers. Conclusion:The current smoking rate among the occupational population in Beijing is lower than the national level during the same period, but the exposure rate to second-hand smoke is relatively high. Age, educational level, job nature and gender are related factors of smoking.

Objective:To investigate the value of ultra micro angiography（UMA）imaging in evaluating the inflammation activity of pediatric Crohn's disease（CD）patients.Methods:In this prospective study，71 pediatric CD patients confirmed by clinical symptoms，laboratory and ileocolonoscopical results who planed to accept infliximab injection treatments in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from April to December 2024 were included. The CD patients were included and divided into 3 groups according to the pediatric Crohn's disease activity index（PCDAI）score：inactive CD group（ n=44），mild CD group（ n=17），and moderate-to-severe CD group（ n=10）. Before treatment，pediatric CD patients underwent B mode ultrasound（BMUS），the parameters such as bowel wall thickness（BWT），bowel wall stratification，mesenteric lymph nodes（MLNs），and existence of mesenteric fat hypertrophy（MFH）were recorded. Color Doppler flow imaging（CDFI）and UMA were used to evaluate the blood flow in the most thickened diseased bowel wall using Limberg scores. The diffierences of the above parameters among the 3 groups were compared. The diagnostic performance of UMA and CDFI in assessing the inflammatory activity of pediatric CD was evaluated. Results:There were statistically significant differences in BWT among the 3 groups（all P<0.05）. However，there were no statistically significant differences in MLNs among the 3 groups（all P>0.05）. Compared with the inactive CD，there were statistically significant differences in bowel wall stratification and MFH in both the mild and moderate-to-severe CD groups（all P<0.05）. When assessing bowel wall blood flow signals using CDFI，there was no statistically significant difference in blood flow signals in the bowel wall of the mild CD compared with the inactive CD（ P>0.05）. However，the blood flow signals in the bowel wall of the moderate-to-severe CD was significantly increased（ P<0.05）. There was also statistically significant difference in blood flow signals in the bowel wall between the mild and moderate-to-severe CD groups（ P<0.05）. When assessing bowel wall blood flow using UMA，there were statistically significant differences in blood flow signals in the bowel wall among all 3 groups（all P<0.05）. As the degree of inflammation increased，the blood flow signals in the bowel wall also increased significantly. ROC analysis revealed that diagnostic performance of the UMA-BMUS model was significantly better than that of the CDFI-BMUS model（AUC 0.945 vs. 0.873，sensitivity 88.9% vs. 74.1%，specificity 97.7% vs. 95.5%；all P<0.05）. Conclusions:By sensitively depicting the low-velocity and tiny blood flow signals of the inflamed bowel wall，UMA is an effective noninvasive imaging method to make semi-quantitative evaluation of the activity of pediatric Crohn's disease.

Objective:To investigate the effect of intestinal air cavity on dose distribution of volumetric intensity modulated arc therapy (VMAT) for cervical cancer.Methods:A total of 10 patients who underwent radiotherapy for cervical cancer at Suzhou Municipal Hospital from January to May 2021 were retrospectively analyzed. For each patient, the same optimization parameters were used to design both a normal full-arc plan and a field avoidance-region plan. The intestinal air cavity identified on computed tomography (CT) imaging was outlined as a separate structure. The dose distribution of the two plans were compared before and after changing the CT value (the electron density of the intestinal air cavity) to 0, using a paired t-test. Additionally, consecutive three-week cone beam CT (CBCT) images were collected for each patient. The intestinal air cavities from the three-week CBCT images were mapped onto the original CT, and the dose distributions of both plans were calculated on the CBCT images. The differences in dose distributions compared to the original plan were analyzed to assess plan robustness. Results:The 105% prescription dose coverage of the target volume ( V105) [(43.62±5.18)%)] within the target area for the field avoidance-region plan was greater than that for the normal full-arc plan [(36.38±10.20)%], with a statistically significant difference ( P<0.05). After modifying the electron density of the intestinal air cavity, the dose distribution in the target area worsened for both plans. However, the V100 and V105 for the field avoidance-region plan [(?0.64±0.58)%, (?2.16±1.66)%] were smaller than those for the normal full-arc plan [(?2.52±1.91)%, (?6.79±2.02)%], with a statistically significant difference (both P<0.05).The V30 for the small intestine in the field avoidance-region plan [(40.28±4.77)%] was lower than that in the normal full-arc plan [(42.63±4.82)%]. The V40 for the rectum [(61.70±15.39)%] and the V20 [(36.32±3.09)%, (35.06±5.32)%] and V30 [(17.76±3.05)%, (16.67±8.14)%] for the left and right femoral heads were higher than those in the normal full-arc plan {(59.72±15.13)%, [(31.36±3.97)%, (27.00±7.79%)] and [(12.99±4.55)%, (11.11±7.20)%]}, respectively, with a statistically significant differences (all P<0.05). The changes in V105 on the weekly CBCT images [(3.27±2.91)%, (2.07±2.93)%, (2.14±2.08)%] and V100 on the second and third weeks′ images [(0.44±0.54)%, (0.54±0.50)%] for the field avoidance-region plan were smaller than those for the normal full-arc plan [(8.22±5.87)%, (5.31±3.97)%, (6.91±3.34)% and (1.70±1.53)%, (2.22±1.97)%], with a statistically significant difference (all P<0.05). Conclusions:The field avoidance-region plan demonstrates higher robustness and better small bowel protection than the normal full-arc plan. The influence of intestinal air cavities on dose distribution should be considered during VMAT planing for cervical cancer to guide optimal plan selection.
