ObjectiveTo evaluate the clinical efficacy and economic value of the Jiangsu Traditional Chinese Medicine (TCM) Diagnosis and Treatment Protocol for Dominant Diseases (abbreviated as the Diagnosis and Treatment Protocol) in adult patients with non-severe community-acquired pneumonia (CAP) based on real-world clinical data. MethodsA retrospective real-world cohort study was conducted using electronic medical records of adult patients hospitalized for non-severe CAP from September 1st, 2023 to December 31st, 2024 across 10 TCM hospitals in Jiangsu province. Patients were classified into an exposure group and a non-exposure group based on whether they received Chinese herbal medicine (CHM) according to the Diagnosis and Treatment Protocol. The non-exposure group received only conventional western medicine, while the exposure group additionally received differentiated CHM for at least five consecutive days. Outcomes were compared between two patient groups, including cough resolution rate, sputum resolution rate (assessed by volume, color, and consistency), incidence of abnormal C-reactive protein (CRP), incidence of abnormal white blood cell (WBC) count, and radiographic resolution rate of pulmonary infiltrates on chest imaging. Multivariable logistic regression was performed to identify factors influencing clinical efficacy. Subgroup analyses were conducted according to age, gender, smoking status, history of hypertension, and pneumonia severity score (CURB-65), and the efficacy of treatment for cough and sputum was analyzed within each subgroup. Cost-effectiveness analysis was conducted using cough resolution rate as the outcome measure, evaluating the pharmacoeconomics of the two groups. ResultsA total of 1688 patients were included with 1293 in the exposure group and 395 in the non-exposure group. Compared to the non-exposure group, the exposure group demonstrated significantly higher resolution rates of cough, sputum volume, color, and consistency, as well as a significantly lower incidence of abnormal CRP (P<0.05). No statistically significant difference was observed between the groups in terms of abnormal WBC count and radiographic resolution rate of pulmonary infiltrates (P>0.05). Logistic regression analysis showed that the cough resolution rate in the exposure group was 1.83 times that of the non-exposure group, while the probabilities of resolution in sputum volume, color, and consistency were 1.37, 2.09, and 1.56 times those of the non-exposure group, respectively (P<0.05). Subgroup analyses showed that the exposure group achieved significantly higher cough resolution rates across most subgroups except for populations with a CURB-65 score ≥2 or those with a history of hypertension (P<0.05). Specifically, among females, patients aged ≥18 and <65 years, non-smokers, those without hypertension, and those with a CURB-65 score of 0, the exposure group showed a higher cough resolution rate than the non-exposure group (P<0.05). From an economic perspective, total hospitalization cost, length of stay, antibiotic cost, and CHM cost all differed significantly between groups (P<0.05). The cost-effectiveness ratio (CER) was 10,788.80 CNY/case in the exposure group, while 22,513.80 CNY/case in the non-exposure group. This implies that, compared with the exposure group, the non-exposure group incurred an additional 17,302.27 CNY to achieve one case of cough resolution. When the willingness-to-pay threshold ranged from 0 to 50,000 CNY, the probability of economic advantage was consistently higher in the exposure group than in the non-exposure group. ConclusionOn the basis of conventional western medicine, the addition of CHM in accordance with the Diagnosis and Treatment Protocol can effectively improve clinical symptoms, reduce inflammatory markers, promote clinical recovery, and is more cost-effective in treating adults with non-severe CAP.

ObjectiveTo observe the real‑world effectiveness and economic outcomes of Weishi Qingjin Formula (苇石清金方, WQF) in the treatment of adult community‑acquired pneumonia (CAP) with phlegm‑heat obstructing the lung syndrome. MethodsBased on a multicenter, real-world retrospective cohort study, clinical data were collected from hospitalized adult patients diagnosed with non‑severe CAP and phlegm‑heat obstructing the lung syndrome in 10 traditional Chinese medicine (TCM) hospitals in Jiangsu province. Patients were divided into an exposure group (those who received oral WQF) and a non‑exposure group (those who did not). The following outcomes were compared between the two groups before and after treatment, which were remission rates of clinical symptoms including cough, expectoration (sputum volume, color, consistency), and chest pain, levels of inflammatory markers including C‑reactive protein (CRP) and white blood cell count (WBC), and the rate of pulmonary inflammatory absorption on chest CT. Subgroup analyses were performed based on age, gender, smoking status, presence of hypertension, and the severity of community-acquired pneumonia (CURB‑65) score, comparing the two groups in terms of cough remission rate, chest pain remission rate, and chest CT absorption rate. For health economic evaluation, cost‑effectiveness analysis was used to calculate the cost‑effectiveness ratio (CER) and incremental cost‑effectiveness ratio (ICER). Univariate sensitivity analysis and probabilistic sensitivity analysis were performed to test the robustness of the results. ResultsA total of 647 patients in the exposure group and 1491 patients in the non-exposure group were included in the final statistical analysis. There was no statistically significant difference in length of hospital stay, gender, marital status, smoking history, bronchoscopy history, and comorbidities between the groups (P>0.05), but age, CURB-65 score, and antibiotic use. The exposure group had significantly higher remission rates of cough and sputum consistency than the non-exposure group (P<0.05). After adjusting for confounders using propensity score matching and logistic regression, the cough remission rate in the exposure group was 1.49 times that of the non-exposure group (P<0.01). No significant difference was observed between groups in the reduction rates of CRP and WBC, and in the rate of pulmonary inflammatory absorption on chest CT (P>0.05). Subgroup analyses revealed that the cough remission rate in the exposure group was significantly better than that in the non-exposure group except for patients aged ≥65 years, smokers, hypertensive patients, those using other type antibiotics or not using antibiotics, and those with a CURB-65 score ≥1 (P<0.05). Among smokers, the chest pain remission rate in the exposure group was 4.38 times that of the non-exposure group (P<0.01). No significant difference in chest CT absorption rate was found between groups across subgroups of gender, age, hypertension status, or antibiotic type (P>0.05). In terms of economic evaluation, CER was 10,877.60 CNY/case in the exposure group and 16,773.10 CNY/case in the non-exposure group. Compared to the exposure group, the non-exposure group incurred an additional 15,034.26 CNY to achieve one case of cough resolution, indicating a more favorable cost-effectiveness profile. Probabilistic sensitivity analysis yielded results consistent with the cost-effectiveness analysis, confirming the robustness of the findings. ConclusionWQF demonstrates significant efficacy in improving cough symptoms in the treatment of adult CAP with phlegm-heat obstructing the lung syndrome, and also exhibits favorable economic benefits.

Objective: To investigate the distribution frequency and molecular mechanism of the rare blood type Lu(a-b-) in Shenzhen, and to compare the polymorphisms of the Lutheran blood group system encoding gene LU and the In (Lu) phenotype-related gene KLF1 among Han Chinese, Indian, and Uyghur populations in Xinjiang. Methods: Serological methods were used to screen the Lu(a-b-) phenotype of blood donors in Shenzhen. Third-generation sequencing was employed to sequence the full-length of the LU and KLF1 genes in Lu (a-b-) phenotype samples as well as the samples from the Han Chinese, Indians, and Uyghur population, followed by analysis of gene haplotypes frequencies. Results: Ten individuals with the Lu(a-b-) phenotype were screened out of 14 367 blood donors in Shenzhen, yielding a frequency of approximately 0.07%. Only 2 cases showed mutations in the coding region of the LU gene, while all individuals showed heterozygous mutations in the coding region of the KLF1 gene. The highest mutation frequencies of the LU and KLF1 genes were observed in the Uyghur population in Xinjiang and the Han Chinese in Shenzhen, respectively. Conclusion: All Lu(a-b-) phenotypes are of the In (Lu) type, and their formation mechanism is mainly related to KLF1 gene mutations. Both the LU and KLF1 genes exhibit significant polymorphism in the Han Chinese, Indians, and Uyghur populations.

Environmental pollution is a significant public health challenge worldwide, and investigating the causal relationship between environmental exposure and population health outcomes is a key objective of environmental epidemiology research. In recent years, the complexity of environmental exposures has increasingly come to the forefront, making it challenging for observational studies that dominate environmental epidemiology to accurately estimate causal effects. Causal inference methods are particularly advantageous in controlling for confounding factors, thus holding great potential in environmental epidemiology research. Researchers can use appropriate causal inference methods to simulate the process of randomization, providing strong support for revealing the causal relationship between environmental exposure and health outcomes. However, there is a lack of reviews on the application of causal inference methods in environmental epidemiology studies in China. Therefore, this study introduced the basic principles of common causal inference statistical methods in environmental epidemiology, summarized the applicable conditions, advantages and disadvantages of various methods, and provided R software implementation codes for these methods, aiming to offer guidance for optimizing research design and practicing causal inference statistical methods.
7.Longitudinal cohort study on pubertal development trajectories of testicular and breast development among children
Chinese Journal of School Health 2026;47(3):408-412
Objective:
To characterize longitudinal trajectories of testicular development in boys and breast development in girls, so as to provide reference data for understanding patterns of pubertal sexual maturation.
Methods:
Based on the Shanghai Pudong New Area Cohort Study on Growth, Development and Health in Children and Adolescents, a baseline survey was conducted in 2020 using a mult stage cluster random sampling method. A total of 2 184 children who completed all follow ups during the primary school period from 13 elementary schools in Pudong New Area,Shanghai,with annual follow ups during 2021-2025. Testicular volume and Tanner stage of breast development were assessed by professional physicians using standardized visual inspection and palpation. The age distribution of testicular volume and breast development was fitted by using cumulative link mixed models and Turnbull s nonparametric maximum likelihood estimation method.
Results:
Median ages for testicular volumes of 2, 3, 4 and 5 mL in boys were 7.07, 9.24, 10.29, and 11.57 years old, respectively. Median ages for Tanner breast stages Ⅱ, Ⅲ, Ⅳ, and Ⅴ in girls were 8.55 , 10.17, 11.18, and 13.78 years old, respectively. Based on overweight and obesity, stratified analysis showed that earlier pubertal onset among overweight/obesity children, and the key milestones for pubertal initiation were testicular volume reaching 4 mL in boys and breast Tanner II in girls for 10.29, 10.83; 8.18, 9.00 years.
Conclusion
Overweight and obesity are associated with earlier pubertal initiation,but there are certain gender and developmental stage specific patterns.

OBJECTIVE To explore a model for constructing a platform for medical institution formulation and provide insights for promoting their development. METHODS By systematically reviewing the development status and challenges of medical institution preparations in China, and based on the theory of industry-university-research collaborative innovation, the organizational structure, collaborative processes, and safeguard mechanisms of the platform were designed. RESULTS & CONCLUSIONS Medical institution formulations in China mainly faced challenges such as weak research and development (R&D) capacity, uneven quality standards, and blocked transformation pathways. This study established a full-chain, whole- industry collaborative innovation network covering the government, medical institutions, universities/research institutes, pharmaceutical enterprises, and the market, forming a new “government-industry-university-research-application” five-in-one platform model for medical institution formulations. By establishing mechanisms such as multi-entity collaborative cooperation, full- chain intellectual property management, contribution-based benefit distribution, staged risk-sharing, and third-party evaluation, the model clarified the responsibilities and collaborative pathways of all parties. The new model highlights the whole-process transformation of clinical experience-based prescriptions, enabling precise alignment between clinical needs and technological R&D, as well as between preparation achievements and industrial transformation. While breaking down the barriers of traditional platform construction, it effectively achieves optimal resource allocation and complementary advantages, addresses problems emerging in the development of medical institution preparations, and provides reference value for the formulation of relevant systems.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

Objective:
To evaluate the performance of 5T magnetic resonance imaging (MRI) in visualizing dental pulp and periodontal ligament (PDL) tissues in vivo in the young adult population, thereby providing a basis for the application of high-field MRI technology in clinical oral examinations.
Methods:
The study was approved by the Ethics Committee of the hospital. A total of 15 healthy volunteers (413 permanent teeth altogether) were recruited and underwent full-mouth 5T MRI scans. Among them, six volunteers (168 permanent teeth) also received both 3T MRI and cone-beam computed tomography (CBCT) scans. Two dental specialists independently evaluated the imaging quality of the dental pulp and PDL on the images using a 5-point Likert scale and recorded the number of detectable root canals for each tooth. Inter-rater agreement was assessed using weighted kappa statistics and intraclass correlation coefficient (ICC). Non-parametric tests were employed to compare differences in imaging performance among different tissue structures, tooth positions, and imaging modalities.
Results:
5T MRI can achieve in vivo imaging for most dental pulp tissues and partial periodontal membrane structures. There was a high level of agreement between the two raters in their imaging scores for the dental pulp and PDL (dental pulp κ = 0.934, PDL κ = 0.737). The imaging scores for dental pulp were significantly higher than those for PDL (P < 0.001), and the scores for molar dental pulp were lower than those for premolars and anterior teeth. In the multimodal comparison involving six volunteers, the raters showed good consistency in scoring dental pulp and PDL imaging across 5T MRI, 3T MRI, and CBCT, as well as in root canal counts (5T MRI for dental pulp κ = 0.971, 3T MRI for dental pulp κ = 0.933, CBCT for dental pulp κ = 0.964; 5T MRI for PDL κ = 0.625, 3T MRI for PDL κ = 0.667, CBCT for PDL κ = 0.571; ICC for root canal counts all ≥ 0.990). The imaging scores for dental pulp and PDL using 5T MRI were significantly higher than those using 3T MRI (dental pulp: P < 0.001; PDL: P = 0.022), but there was no statistically significant difference in the detection rate of the number of root canals between the two (P > 0.05). Although the imaging scores for dental pulp and PDL as well as the detection rate of the number of root canals with 5T MRI were inferior to those with CBCT (dental pulp: P < 0.001; PDL: P = 0.02; number of root canals: P < 0.05), 5T MRI can truly achieve "direct imaging" of these two soft tissues.
Conclusion
5T MRI enables effective in vivo direct imaging of dental pulp and PDL tissues in the young adult population, indicating its potential clinical application value in the diagnosis and treatment of pulp and periodontal diseases.
