OBJECTIVE To compare the antihypertensive efficacy of sacubitril/valsartan versus benazepril in patients with perimenopausal hypertension， as well as their impacts on ventricular remodeling and inflammatory fibrosis. METHODS A total of 206 perimenopausal hypertensive patients in our hospital from January 1， 2023 to December 30， 2024 were retrospectively included.These patients were enrolled and divided into benazepril group （105 cases） and sacubitril/valsartan group （101 cases）. Benazepril group received Benazepril hydrochloride tablet， and sacubitril/valsartan group received Sacubitril valsartan sodium tablet. All patients were treated for 6 months. The blood pressure（systolic blood pressure and diastolic blood pressure） and blood pressure control status before and after treatment， echocardiographic indicators （left ventricular ejection fraction， left ventricular mass index， relative wall thickness， and early-diastolic peak transmitral flow velocity/early-diastolic peak velocity of the mitral annulus）， inflammatory fibrosis related indicators（high-sensitivity C-reactive protein，ratio of monocytes to lymphocytes，and ratio of neutrophils to lymphocytes）， as well as the occurrence of adverse reactions（hypotension，hyperkalemia，and angioedema） were observed in both groups before and after treatment. RESULTS The blood pressure control rate was significantly higher in the sacubitril/valsartan group than in benazepril group （ P ＜0.05）. After treatment， the blood pressure， echocardiographic indicators（except for left ventricular ejection fraction） ，and inflammatory fibrosis related indicators were significantly lower than those before treatment within the same group， and the sacubitril/valsartan group were significantly lower than the benazepril group （ P ＜0.05）. There were no statistically significant differences in the incidence of hypotension， hyperkalemia， angioedema， and overall adverse drug reactions between the two groups （ P ＞0.05）. CONCLUSIONS Compared with benazepril， sacubitril/valsartan provides superior blood-pressure control， reverses ventricular remodeling， attenuates inflammatory fibrosis in perimenopausal hypertensive patients， while maintaining a similar safety profile.

Objective: To explore the relationship between socio ecological risk factors (SERF), physical activity (PA) developmental trajectories, and depressive symptoms among junior and senior high school students in Tianjin, in order to provide theoretical support for comprehensive interventions for adolescent depression. Methods: A longitudinal follow up design was adopted. In September 2022, a baseline survey was conducted using a stratified cluster random sampling method in two junior high schools and two senior high schools in Tianjin, collecting data on students basic information, SERF, PA, and depressive symptoms. Two follow up surveys were conducted in September 2023 and 2024, yielding 588 valid participants. Latent class growth analysis (LCGA) was used to identify PA developmental trajectory categories among junior and senior high school students. Logistic regression was applied to examine the associations between depressive symptoms and SERF as well as PA trajectories. Results: The detection rates of depressive symptoms among Tianjin junior and senior high school students over the three years were 26.53%, 20.24%, and 21.26 %, respectively. Depressive symptoms were positively correlated with SERF ( OR=1.04, 95%CI=1.03-1.05, P <0.05). The highest risks were observed in the individual dimension and family dimension ( OR =1.28, 1.21, both P <0.05). LCGA identified three PA trajectory groups:persistently low level (80.65%), persistently high level (4.58%), and slowly increasing group ( 14.77 %). Multivariate regression analysis showed that compared with the persistently low level PA, the slowly increasing PA significantly reduced the risk of depressive symptoms ( OR=0.44, 95%CI =0.20-0.88), while SERF still increased the risk of depressive symptoms ( OR=1.04, 95%CI =1.03-1.05) (both P <0.05). Conclusion SERF are risk factors for depression symptoms among junior and senior high school students, whereas slowly increasing PA development trajectory demonstrates a protective effect.

Objective:To report the nationwide surveillance results of pathogenic profiles and antimicrobial resistance patterns of Gram-positive bloodstream infections in China in 2023.Methods:The clinical isolates of Gram-posttive bacteria from blood cultures were collected in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）during January to December 2023. Antimicrobial susceptibility testing was performed using the dilution method recommended by the Clinical and Laboratory Standards Institute（CLSI）. Statistical analyses were conducted using WHONET 5.6 and SPSS 25.0 software.Results:A total of 4 385 Gram-positive bacterial isolates were obtained from 60 participating center. The top five pathogens were Staphylococcus aureus（ n=1 544，35.2%），coagulase-negative Staphylococci（ n=1 441，32.9%）， Enterococcus faecium（ n=574，13.1%）， Enterococcus faecalis（ n=385，8.8%），and α-hemolytic Streptococci（ n=187，4.3%）. The prevalence of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）was 26.2%（405/1 544）and 69.8%（1 006/1 441），respectively. Notably，all Staphylococci remained susceptible to glycopeptide or daptomycin. Staphylococcus aureus demonstrated excellent susceptibility（>97.0%）to cephalobiol，rifampicin，trimethoprim-sulfamethoxazole，linezolid，minocycline，tigecycline，and eravacycline. No Enterococcus exhibiting resistance to linezolid were detected. Glycopeptide resistance was uncommon but more frequent in Enterococcus faecium（resistance to vancomycin and teicoplanin：both 1.7%）compared to Enterococcus faecalis（both 0.3%）. The detection rates of MRSA and MRCNS exhibited significant regional variations across the country（ χ2=17.674 and 148.650，respectively，both P<0.001）. No vancomycin-resistant Enterococci were detected in central China. Institutional comparison demonstrated higher prevalence of MRSA（ χ2=14.111， P<0.001）and MRCNS（ χ2=4.828， P=0.028）in provincial hospitals than that in municipal hospitals. Socioeconomic analysis identified elevated detection rates of both MRSA（ χ2=18.986， P<0.001）and MRCNS（ χ2=4.477， P=0.034）in less developed regions（per capita GDP

The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 64.6%（370/573），while more than 80.0% of CRAB complex was sensitive to tigecycline，eravacycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 17.0%（99/581）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of important Gram-negative bacteria resistance among different regions in China，with statistically significant differences in the prevalence of CREC，CRKP，CRPA and CRAB complex（ χ2=10.6，28.6，10.8 and 19.3， P<0.05）. The prevalence of ESBL-producing Escherichia coli， CREC，CRAB complex and CRKP were higher in provincial hospitals than those in municipal hospitals（ χ2=12.5，9.8，12.7 and 57.8，all P<0.01）. Conclusions:Gram-negative bacteria are the main pathogens causing bloodstream infections in China，and Escherichia coli is ranked in the top，while the trend of Klebsiella pneumoniae increases continuously with time. CRKP infection shows a slow upward trend，CREC infecton maintains a low prevalence level，and CRAB complex infection continues to exhibit a high prevalence rate. The composition and resistance patterns of pathogens causing bloodstream infections vary to some extent across different regions and levels of hospitals in China.

Objective To investigate the neuroprotective effect of Dendrobium nobile Lindl(DNL)extract in a Caenorhabditis elegans(C.elegans)model of Parkinson's disease(PD).Methods C.elegans NL5901 and 6-hydroxydopamine(6-OHDA)induced N2,BZ555,PD4521,and CB7272 C.elegans strains were treated with DNL 7.5,15,and 30 mg/L.The survival rate,basal slowing response rate,α-synuclein(α-syn)aggregation,dopaminergic neurons(DNs),mitochondrial distribution density of body wall muscle cells,and protein levels in the membrane were observed.In addition,reactive oxygen species(ROS),superoxide dismutase(SOD)and glutathione(GSH)in 6-OHDA induced N2 was detected to explore the effect of DNL on the antioxidative stress ability of PD C.elegans models.Results Compared with that in the model group,the DN fluorescence intensity was significantly increased in nematodes treated with DNL and levodopa(L-DOPA)(P＜0.05,P＜0.0001),α-syn aggregation was significantly decreased(P＜0.05,P＜0.001,P＜0.0001),the basal slowing rate(P＜0.05,P＜0.01,P＜0.001),mitochondrial density(P＜0.05,P＜0.01,P＜0.001),mitochondrial intima protein content(P＜0.05,P＜0.001,P＜0.0001),SOD content(P＜0.05),and GSH content were all increased.The ROS content was reduced in nematodes(P＜0.01).The lifespans of N2 wild-type and PD C.elegans models were prolonged after DNL treatment(P＜0.05,P＜0.01,P＜0.001).Conclusions DNL can effectively improve motor paralysis in a C.elegans PD model,improve DN degradation,inhibit α-syn aggregation and neuronal damage,increase the antioxidative stress ability,and slow the aging process in C.elegans.

MethodsMedical records, including demographic information, diagnosis and treatment information, laboratory testing results, treatment outcomes, patient prognoses, and etc., of all the patients registered for first-time management, with the disease type of pulmonary tuberculosis in Jing’an District from January 1, 2018 to December 31, 2023 were extracted from the Tuberculosis Management Information System of China’s Disease Control and Prevention Information System.The reported incidence rate of pulmonary tuberculosis from 2018 to 2023 was analyzed. Additionally, the delay rate for medical consultation, diagnostic delay rate, prevalence of pulmonary cavity, rate of sputum smear-positive, sputum conversion rate of smear-positive patients after 2 months, proportion of deaths attributable to pulmonary tuberculosis or other causes, and the proportion of patients with treatment duration >1 year in 2018‒2019, 2020‒2022, and 2023 were compared, respectively. ResultsA total of 1 378 pulmonary tuberculosis patients were registered for management in Jing’an District in 2018‒2023, with a reported incidence rate of 25.97/100 000, 25.72/100 000, 23.93/100 000, 22.36/100 000, 18.18/100 000, and 22.32/100 000, respectively. Meanwhile, the overall reported incidence rates in 2018‒2019, 2020‒2022, and 2023 were 25.84/100 000, 21.53/100 000, and 22.32/100 000, respectively. The median age of the patients was 56 (33, 67) years, with a male-to-female ratio of 1.94∶1. The patients with a household registration of Shanghai accounted for 70.75%, among whom those aged between 61‒<71 years were the majority. Whereas, those aged between 31‒<41 years accounted for a higher proportion in the long-term resident population. The median delay times of patient’s medical consultation, diagnosis, and case-finding were 25 (19, 33) days, 29 (21, 43) days, and 41 (32, 66) days, respectively. The delay rate for medical consultation was higher in 2020‒2022 (47.99%) and 2023 (46.89%), but lower in 2018‒2019 (31.02%). In 2018‒2019, 2020‒2022, and 2023, the diagnostic delay rate was 12.41% (68/548), 13.53% (84/621), and 16.75% (35/209), respectively. Besides, during the same time the delay rate in case-finding was 19.53%, 27.05% and 34.45%, respectively, all exhibited an increasing trend. Furthermore, the rate of patients with pulmonary cavity was 16.06%, 14.98%, and 11.00%, respectively, showing a decreasing trend. Furthermore, the rate of sputum smear-positive was 27.19%, 33.33% and 32.54%, while the sputum conversion rate of smear-positive patients after 2 months was 81.21%, 85.02% and 89.71%. The mortality rates due to tuberculosis and other causes were 3.10%, 5.64%, and 3.83%, respectively. The proportion of patients with a treatment duration of ≥365 days was 44.27% in 2018‒2019, 39.93% in 2020‒2022 and 26.60% in 2023. ConclusionThe overall reported incidence rate of pulmonary tuberculosis in Jing’an District showed a decline trend from 2018‒2022, with a slight rebound in 2023. Targeted interventions should be prioritized for the elderly with local household registration and young permanent residents without Shanghai household registration.

Objective: To establish a progressive research strategy for “colonic components analysis - efficacy verification and mechanism exploration - gut microbiota”, screen pharmacodynamic substances, and investigate their mechanism via gut microbiota. Methods: The pharmacodynamics of Gegen Qinlian decoction (GQD) were assessed using a mouse model of dextran sulfate sodium-induced ulcerative colitis (UC). Ultra-performance liquid chromatography-quadrupole-orbitrap mass spectrometer was used to identify the prototype and metabolic components of GQD in the colon during UC. To analyze the structure and function of characteristic genera of GQD and its active components, 16S rRNA sequencing was performed. Results: We identified 67 prototypic and 14 metabolic components of GQD in the UC colon. The primary prototype components are flavonoids and alkaloids, including puerarin (PUE), baicalin (BAI), and berberine (BER). The metabolism was predominantly sulfonation. Efficacy verification showed that the main active components, puerarin, baicalin, and berberine, had good therapeutic effects on UC. The results of 16S rRNA gene sequencing showed that GQD improved UC by regulating the structure and function of the gut microbiota. The abundance of gut microbiota involved in the metabolism of the prototype components was influenced by the corresponding components. The function prediction results showed that PUE was the most comparable to GQD, with 24 consistent pathways. BAI and BER showed comparable gut microbiota regulation pathways. Characteristic pathways of BER include glucometabolic processes. Conclusion This study focused on the key issues in the gut microbiota pathway and developed a progressive research strategy to understand the transformation mechanisms of colonic components. This research systematically analyzed the active components and metabolic transformation of GQD in the colon during the pathological state of UC, as well as changes in the structure and function of the gut microbiota, clarified the mechanism of GQD and its active components in improving UC via the gut microbiota pathway.

Objective To explore the efficacy and safety of standard pulsed radiofrequency for treating rare-site glomus tumors.Methods A prospective self before-and-after control study was conducted and 6 pa-tients diagnosed as glomus tumors in the pain department of Yongkang Municipal First People's Hospital from June 2022 to January 2023 served as the study subjects.Among them,1 case was located in the outer beam of deltoid muscle in the upper arm,and 5 cases were located under the nail beds of the hands/feet.All subjects underwent the standard pulsed radiofrequency treatment under ultrasound guidance and were fol-lowed up for at least 12 months.The changes in the preoperative and postoperative Numerical Rating Scale(NRS)scores were observed,and the changes in the"typical triad",healing degree of the nail growth matrix and recurrence of pain were recorded.Results The postoperative follow-up results showed that all patients had significant decreases in NRS scores,indicating that the pain degree obtained the effective control.Among them,4 patients did not experience the pain recurrence after adopting the standard pulsed radiofrequency;1 pa-tient had pain recurrence in postoperative 6 months and the tumor body was ultimately removed by surgery.Apart from the patient 2 developing transient subungual congestion,no significant adverse events were observed.Conclusion The standard pulsed radiofrequency treatment is a safe and effective therapeutic method for pain caused by rare-site glomus tumors.

Objective To investigate the impact of phase Ⅱ cardiac rehabilitation on the rehabilitation needs and physical activity status of patients after coronary heart disease intervention.Methods A total of 90 patients with coronary heart disease who underwent percutaneous coronary intervention(PCI)in the Coronary Heart Disease Center of the hospital from August 2023 to August 2024 were selected as the research subjects.They were subjected to a 12-week standardized phase Ⅱ cardiac rehabilitation training.General data survey forms,cardiac rehabilitation scales,and the International Physical Activity Questionnaire were used for scale surveys to understand the patients' needs before and after rehabilitation and their weekly physical activity en-ergy expenditure.The cardiopulmonary exercise test gold standard,which reflects exercise capacity through three indicators-maximum oxygen uptake(VO2 max),anaerobic threshold(AT),and metabolic equivalents(MET),were used to compare the physical activity status before and after cardiac rehabilitation.Results Compared with before the implementation,after the implementation of cardiac rehabilitation,the autonomy score in-creased(21.36±1.85 vs.16.73±3.28),the process anxiety(12.60±3.87 vs.14.27±2.12)and outcome anxiety scores(2.31±1.76 vs.4.56±3.56)decreased,the level of low-intensity physical activity decreased[(2 711.62±1 487.09)min/week vs.(3 845.97±2 083.71)min/week],the levels of moderate-intensity[(1 314.67±783.54)min/week vs.(686.22±126.79)min/week],high-intensity[(1 861.33±798.27)min/week vs.(112.00±40.77)min/week],and total physical activity increased[(5 887.62±2 843.54)min/week vs.(4 644.19±2 287.16)min/week].The levels of VO2 max[(28.11±14.28)mL·min-1·kg-1 vs.(23.82±12.34)mL·min-1·kg-1],AT[(16.06±5.41)mL·min-1·kg-1 vs.(13.53±4.56)mL·min-1·kg-1],and MET[(6.89±1.59)mL·min-1·kg-1 vs.(5.78±1.21)mL·min-1·kg-1]all in-creased,with statistically significant differences(P＜0.05).Conclusion Phase Ⅱ rehabilitation after PCI can effectively improve patients' physical activity levels.

Objective:To report the clinical, imaging, and pathological features of a case of MYH7 gene-related scapuloperoneal myosin storage myopathy. Methods:Clinical data were collected from a patient with MYH7 gene-related scapuloperoneal myosin storage myopathy who presented to Peking University First Hospital in February 2025. The patient was evaluated with muscle magnetic resonance imaging, muscle biopsy, and whole-exome sequencing. Results:The patient was a 52-year-old female, with a 12-year history of progressive difficulty in foot dorsiflexion, exercise-induced fatigue, and lower limb pain. Over the past 3 years, she developed proximal upper limb weakness and post-exertional myalgia. Physical examination revealed scapuloperoneal weakness distribution accompanied by sensorineural hearing loss. Electromyography demonstrated myogenic changes in the deltoid and tibialis anterior muscles. Serum creatine kinase levels were within normal limits. Lower limb magnetic resonance imaging showed mild atrophy of the thigh muscles and significant fatty infiltration in the tibialis anterior, extensor hallucis longus, and extensor digitorum longus. Tibialis anterior muscle biopsy revealed dystrophic-like changes with sub-sarcolemmal hyaline bodies containing abundant granulofilamentous material. Whole exome sequencing identified a heterozygous pathogenic variant of c.5352_5354del(p.K1784del) in the MYH7 gene. Conclusions:This patient is the first reported one in China with MYH7 gene-related scapuloperoneal myosin storage myopathy, exhibiting characteristic scapuloperoneal weakness, selective fatty infiltration of the anterior lower leg muscles on imaging and sub-sarcolemmal hyaline body pathological changes. The diagnosis of this disease relies on characteristic pathological findings and genetic test results.
