The onset and progression of chronic heart failure （CHF） are closely associated with myocardial energy metabolism disorders， and this pathological process significantly affects patient prognosis. Traditional Chinese medicine （TCM）， grounded in time-based medical theories such as the correspondence between humans and nature and the theory of circadian flow of meridians （Ziwu Liuzhu）， exhibits intrinsic consistency with modern circadian rhythm theory， providing a unique theoretical framework for understanding and intervening in CHF from a temporal perspective. This article systematically explores the impact of circadian rhythms on energy metabolism and the potential mechanisms by which TCM active ingredients intervene in CHF through a review of relevant literature. It is found that various TCM active ingredients， including flavonoids （such as nobiletin）， alkaloids （such as berberine）， and polyphenols （such as resveratrol）， can improve mitochondrial function， promote fatty acid oxidation， enhance glucose uptake and utilization efficiency， maintain metabolic balance， and alleviate oxidative stress and inflammatory responses in myocardial cells by regulating the expression and rhythms of core circadian clock genes such as CLOCK， BMAL1， PER， and CRY. These actions thereby correct energy metabolism disorders and improve cardiac function. Further exploration of the interaction mechanisms between these components and the circadian rhythms holds promise for providing novel theoretical foundations and potential intervention strategies for the prevention and treatment of CHF.

ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective To investigate occupational exposure levels of lead, arsenic and cadmium in the lead smelting plant of Hunan Shui Kou Shan Nonferrous Metals Group Co. Ltd., analyze their effects on health of employees, and compare the applicability of different occupational health risk assessment methods, and to provide a basis for prevention and control of occupational exposure risks in enterprises. Methods According to systematic sampling method, 380 employees with lead, arsenic and cadmium exposure (exposure group) and 100 non-exposure employees (non-exposure group) were selected from 2022 to 2024 for on-site investigation of occupational health [concentration time-weighted average (C_TWA)] and physical examination. The risk was evaluated by qualitative assessment method, the U.S. Environmental Protection Agency (EPA) inhalation risk assessment method, and the Singapore Ministry of Manpower (MOM) semi-quantitative method. The consistency was analyzed by the Kappa test. Results C_TWA values of lead, arsenic, and cadmium in all positions were lower than the occupational exposure limit (OEL). The levels of blood lead, urine arsenic, and urine cadmium, as well as the prevalence of multiple systems in the exposure group were significantly higher than those in the non-exposure group (P<0.05). The proportions of chronic lead, arsenic, and cadmium poisoning were increasing year by year in the exposure group (P<0.05). The qualitative assessment method mainly indicated low and medium risk, while the EPA and MOM methods mainly indicated medium and high risk, with good agreement between the two methods (Kappa=0.676, P<0.05). Conclusion Although the enterprise meets the C_TWA standards, there are still occupational health risks of lead, arsenic, and cadmium. The EPA inhalation risk assessment method is more applicable.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

Objective To explore the medication rules and mechanism of Xin'an physicians in the treatment of diabetes mellitus.Methods The prescriptions for the treatment of diabetes mellitus in Xin'an medical writings were collected.The core drug prescriptions were obtained by using IBM SPSS Modeler 18.0 for dispensing association rules as well as complex network analysis,and the cluster analysis of high-frequency traditional Chinese medicines was carried out by using IBM SPSS Statistics 25.0.The active ingredients and targets of the core drugs were extracted from the BATMAN-TCM database.The GeneCards database was used to search for diabetes gene targets,and after obtaining the intersecting targets,the STRING online platform was imported to construct the protein interactions network,and screened the core genes by using the Cytoscape 3.9.1 software,and imported into the DAVID database for GO function and KEGG pathway enrichment analysis.Results A total of 135 valid prescriptions were included,involving 184 flavors of traditional Chinese medicines,with cold and mild properties.Sweet,bitter and pungent flavors,and the main attributes of lung,spleen,kidney,stomach and heart meridians.The association rules mined 14 pairs of commonly used medicine pairs.Cluster analysis clustered the top 20 traditional Chinese medicines into five cluster groups.Complex network visualization analysis formed a core prescription consisting of honey-fried licorice root,ginseng,rhizoma anemarrhenae,ophiopogon japonicus,poria cocos.The core prescription drugs were screened for 164 effective active ingredients,1,498 action targets,1,995 diabetes gene targets,404 intersecting targets,10 core targets were extracted,and a total of 1,363 items covering BP were obtained from GO functional enrichment analysis,129 items involving CC,264 items containing MF,and 206 items of KEGG signaling pathway.Conclusion The prescriptions and medicines used by Xin'an doctors in the treatment of diabetes mellitus reflect the academic idea of"treating both the symptoms and the root cause"as well as the therapeutic thought of"using cold and warmth,supplementing with sweetness and warmth,opening up and lowering with bitterness,cultivating the earth and generating gold,and consolidating the root and cultivating the elements",which provide references for the treatment of diabetes mellitus in today's clinics.

BACKGROUND:Hemivertebra deformity should be treated surgically at an early age,but the risk factors for progression of deformity after hemivertebral resection have not been established.OBJECTIVE:To investigate the curative effect of one-stage posterior hemivertebrae resection and pedicle screw fixation in the treatment of congenital scoliosis,and to further explore the risk factors causing the progression of postoperative deformity.METHODS:The medical records of patients who underwent pedicle screw-rod fixation for unilateral hemivertebral deformity from January 2012 to February 2020 and were followed up for at least 2 years were retrospectively analyzed,and a total of 116 patients met the inclusion criteria.All patients were treated with standing anterior and lateral spinal radiographs taken before,after and at each follow-up time point.The segment Cobb angle,the total scoliosis Cobb angle,the proximal complementary Cobb angle,the distal complementary Cobb angle,and the coronal balance distance,apical vertebra distance,upper instrumented vertebra tilt,upper instrumented vertebra disc angle,lower instrumented vertebra tilt,lower instrumented vertebra disc angle,segmental kyphosis/lordosis,thoracic kyphosis,lumbar lordosis and sagittal vertical axis were measured.The progression of deformity and complications were also recorded.RESULTS AND CONCLUSION:(1)Segment Cobb,total scoliosis Cobb,segmental kyphosis,proximal complementary Cobb,and distal complementary Cobb were significantly corrected after operation(P＜0.05),and remained corrected at the last follow-up.Thoracic kyphosis,lumbar lordosis,coronal balance distance,and sagittal vertical axis were all in the normal range pre-operation,after operation and at the last follow-up.(2)During follow-up,10 patients developed coronary decompensation,which was characterized by abnormal progression.(3)Independent sample t-test showed that preoperative total scoliosis Cobb,preoperative apical vertebra distance,age,Risser sign,postoperative upper instrument vertebra tilt and postoperative lowest instrumented vertebra tilt were correlated with postoperative malformation progression(P＜0.05).(4)Multivariate Logistic regression analysis showed that postoperative lowest instrumented vertebra tilt was an independent risk factor for postoperative malformation progression(P=0.002,OR=1.526).(5)Receiver operating characteristic curve analysis showed that a postoperative lowest instrumented vertebra tilt of 8.14° was the optimal threshold for deformity progression after hemivertebrae resection and pedicle rod fixation(sensitivity 0.900,specificity 0.906,area under curve:0.926).(6)It is indicated that the treatment of congenital scoliosis with one-stage posterior hemivertebrae resection and pedicle nail fixation can achieve satisfactory orthopedic effect.Postoperative lowest instrumented vertebra tilt greater than 8.14° was an independent risk factor for postoperative coronal decompensation.

Objective To investigate the effects of kaempferol on the oxidative damage and apoptosis of human lens epithelial cells induced by hydrogen peroxide(H2O2),as well as its regulatory role in the Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3)signaling pathway.Methods Human lens epithelial cells HLE-B3 were cultured in vitro and divided into the blank group(no intervention),the model group(400 pmol?L-1 H2O2),the kaempferol group(400 μmol?L-1 H2O2+40 pmol?L-1 kaempferol),the AG490 group(400 pmol?L-1 H2O2+50 μmol?L-1 JAK2/STAT3 signaling pathway inhibitor AG490),the inhibitor group(400 pmol?L-1 H2O2+40 pmol?L-1 kaempferol+50 μmol?L-1 AG490),and the activator group(400 pmol?L-1 H2O2+40 pmol?L-1 kaempferol+0.5 μmol?L-1 JAK2/STAT3 signaling pathway activator C-A1).After 24 h of intervention,Hoechst 33258 staining was used to determine the ap-optosis rate of these cells.Malondialdehyde(MDA)and superoxide dismutase(SOD)kits were used to detect the levels of MDA and SOD.The protein expression levels of Cysteine aspartic protease 3(Caspase-3),B-cell lymphoma-2(Bcl-2),JAK2,STAT3,p-JAK2,and p-STAT3 were detected by Western blot.Results Compared with the blank group,the apop-tosis rate,the MDA level,and the protein expression levels of Caspase-3,p-JAK2,and p-STAT3 increased(all P＜0.05)in the model group,while the protein expression levels of SOD and Bcl-2 decreased(all P＜0.05).Compared with the model group,the apoptosis rate,the MDA level,and the protein expression levels of Caspase-3,p-JAK2,and p-STAT3 decreased in the kaempferol and AG490 groups(all P＜0.05),while the protein expression levels of SOD and Bcl-2 increased(all P＜0.05).Compared with the kaempferol group,the apoptosis rate,the MDA level,and the protein expression levels of Caspase-3,p-JAK2,and p-STAT3 decreased in the inhibitor group,while the protein expression levels of SOD and Bcl-2 in-creased(all P＜0.05);the changes in the above indicators in the activator group were opposite to those in the inhibitor group(all P＜0.05).Conclusion Kaempferol can protect HLE-B3 cells from H2O2-induced oxidative damage and inhibit their apoptosis by inhibiting JAK2/STAT3 signaling pathway.

Objective This study aimed to investigate the efficacy of modified endoscopic autologous cartilage eustachian tube pharyngeal orifice tuboplasty(MEACETT)in patients with patulous eustachian tube(PET).Meth-ods A retrospective analysis was conducted on the clinical data of 27 patients(30 ears)diagnosed with PET who underwent MEACETT.Autologous cartilage was used through the incision at the posterior end of the inferior turbi-nate and filled into the lateral wall of the pharyngeal orifice of the eustachian tube.Without affecting the movement function of the eustachian tube during swallowing,the collapse of the pharyngeal orifice was fully filled.Before and after the surgery,the visual analogue scale(VAS),the eustachian tube dysfunction questionnaire-7(ETDQ-7)and hospital anxiety and depression scale(HADS)was used for assessment to evaluate the surgical efficacy.Results There was no significant difference in depression scores before and after surgery(P＞0.05).However,postopera-tive anxiety scores,ETDQ-7 scores,and VAS scores were significantly lower than preoperative scores(P＜0.05).Among the 27 patients,9 showed significant symptom relief,13 exhibited partial relief,and 5 had no significant change compared to preoperative symptoms.The overall response rate of the treatment(significant relief and partial relief)was 81.48％(22/27).All surgeries were successfully performed.Except for secretory otitis media occurring in 2 cases,no major complications were observed.Conclusion MEACETT demonstrates significant symptom relief in PET patients,with high surgical safety and low complication rates,making it worthy of clinical promotion.

Objective To evaluate the diagnostic efficacy of the R value in tubomanometry(TMM)for the di-agnosis of patulous eustachian tube(PET).Methods The clinical data of 58 patients with PET and 65 controls were retrospectively analyzed.TMM was performed on both groups under nasopharyngeal pressures of 30,40,and 50 mbar respectively.The diagnostic efficacy of the R value for PET was evaluated through receiver operating char-acteristic(ROC)curves.Results In the control group,the average R values under nasopharyngeal pressures of 30,40,and 50 mbar were 0.86±0.50,0.76±0.41,and 0.68±0.34 respectively.In contrast,the corresponding R values in the PET group were significantly lower,which were 0.56±0.38,0.50±0.36,and 0.46±0.38 respec-tively.According to the ROC curve analysis,the areas under the curve(AUC)at these pressures were 0.62,0.74,and 0.74 respectively.The specificity and sensitivity of the R value under nasopharyngeal pressures of 30,40,and 50 mbar were 76.90％and 54.30％,74.60％and 68.10％,86.90％and 54.30％,respectively.Under pressures of 30,40,and 50 mbar,the incidence rates of R＞1 in the control group and the PET group were 29.23％(38/130)and 12.77％(12/94)(x2=8.69,P=0.003),20.00％(26/130)and 6.38％(6/94)(x2=7.20,P=0.007),10.00％(13/130)and 3.19％(3/94)(x2=2.87,P=0.09)respectively.Conclusion Although the low R value in TMM reflects the presence of PET to some extent,it does not provide adequate sensitivity and specificity to serve as an independent diagnostic criterion for PET.
