Facing the requirements of promoting the healthy China initiative and improving people's health, the "bone health program" was proposed in 2024. In-depth development of a traditional Chinese medicine(TCM) prevention and control system is of strategic significance to the implementation of the "bone health program". Focusing on osteoporosis(OP), a representative disease affecting people's bone health, this paper concludes that accelerating the research on the prevention and control of OP by TCM is conducive to enhancing the knowledge and awareness of OP among the public, and it is beneficial to revealing the evolutionary pattern of OP and improving the understanding and management of this disease. Additionally, it can provide an overall framework for and strengthen the systematicity and completeness of the research on the prevention and treatment of OP by TCM. Meanwhile, it can help to explore new research paradigms and optimize the existing research model, so as to promote innovative breakthroughs in the prevention and treatment of bone health-related diseases by TCM. Under the overall layout of the "bone health program", importance should be attached to the early prevention and the innovation of very early diagnosis and intervention of OP. Emphasis should be put on the discovery of the target network of disease and treatment mechanism for revealing the core pathogenesis of OP and the therapeutic mechanism of TCM. In addition to local lesions of the bone and its clinical outcomes, attention should be paid to the development of multiple metabolic complications. The fusion of advanced interdisciplinary technologies should be promoted for OP and its complications, and thus a research and development system based on clinical application scenarios and driven by big data can be built. The measures above will facilitate the progress in the prevention and treatment of OP and other bone diseases by TCM and provide new momentum for enriching and deepening the research connotation of the "bone health program".

Emodin is a hydroxyanthraquinone compound that is widely distributed and has multiple pharmacological activities, including anti-diarrheal, anti-inflammatory, and liver-protective effects. Research indicates that emodin may be one of the main components responsible for inducing hepatotoxicity. However, studies on the mechanisms of liver injury are relatively limited, particularly those related to bile acids(BAs) metabolism. This study aims to systematically investigate the effects of different dosages of emodin on BAs metabolism, providing a basis for the safe clinical use of traditional Chinese medicine(TCM)containing emodin. First, this study evaluated the safety of repeated administration of different dosages of emodin over a 5-week period, with a particular focus on its impact on the liver. Next, the composition and content of BAs in serum and liver were analyzed. Subsequently, qRT-PCR was used to detect the mRNA expression of nuclear receptors and transporters related to BAs metabolism. The results showed that 1 g·kg~(-1) emodin induced hepatic damage, with bile duct hyperplasia as the primary pathological manifestation. It significantly increased the levels of various BAs in the serum and primary BAs(including taurine-conjugated and free BAs) in the liver. Additionally, it downregulated the mRNA expression of farnesoid X receptor(FXR), retinoid X receptor(RXR), and sodium taurocholate cotransporting polypeptide(NTCP), and upregulated the mRNA expression of cholesterol 7α-hydroxylase(CYP7A1) in the liver. Although 0.01 g·kg~(-1) and 0.03 g·kg~(-1) emodin did not induce obvious liver injury, they significantly increased the level of taurine-conjugated BAs in the liver, suggesting a potential interference with BAs homeostasis. In conclusion, 1 g·kg~(-1) emodin may promote the production of primary BAs in the liver by affecting the FXR-RXR-CYP7A1 pathway, inhibit NTCP expression, and reduce BA reabsorption in the liver, resulting in BA accumulation in the peripheral blood. This disruption of BA homeostasis leads to liver injury. Even doses of emodin close to the clinical dose can also have a certain effect on the homeostasis of BAs. Therefore, when using traditional Chinese medicine or formulas containing emodin in clinical practice, it is necessary to regularly monitor liver function indicators and closely monitor the risk of drug-induced liver injury.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective:To study influence of Connect-Introduce-Communicate-Ask-Respond-Exit(CICARE)communication mode on patients with acute heart failure(AHF).Methods:A total of 156 AHF patients treated in our hospital were randomly and equally divided into routine nursing group and CICARE group(received CICARE communication mode based on routine nursing group).Both groups were intervened for one month.General clinical data,hospitalization indexes,scores of Hamilton rating scale for depression(HAMD),Hamilton rating scale for anxiety(HAMA),general self-efficacy scale(GSES)and quality of life scale(QOL-35)before and after inter-vention and incidence of complications were compared between two groups.Results:Compared with routine nursing group,there were significant reductions in first aid time[(42.06±9.77)s vs.(20.27±3.77)s],visit time[(95.67±23.18)min vs.(50.07±11.21)min],admission time[(3.22±0.36)min vs.(2.60±0.67)min]and hospital stay[(22.33±4.82)d vs.(14.13±2.42)d];and scores of HAMD[(14.02±1.42)scores vs.(6.04± 1.57)scores]and HAMA[(13.24±2.07)scores vs.(7.16±2.17)scores]after intervention,and significant rise in scores of GSES[(14.25±3.14)scores vs.(32.03±6.06)scores]and QOL-35[(70.67±5.75)scores vs.(86.93±5.51)scores]in CICARE group after intervention(P=0.001 all).Incidence rate of complications in CICARE group was significantly lower than that of CICARE group(5.13％vs.20.51％,P=0.004).Conclusion:CICARE communication mode can significantly alleviate adverse emotions and improve self-efficacy in patients with acute heart failure.

Objective:To compare the outcomes of robot-assisted laparoscopic partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) in the treatment of tumors in isolated kidney, and analyze the factors influencing postoperative renal function and long-term survival in patients.Methods:A retrospective analysis was conducted on clinical data of 67 patients with tumors in isolated kidney who underwent surgery at the Chinese PLA General Hospital from November 2010 to January 2022. There were 48 males and 19 females, with an average age of (58.6±10.1) years old. The patients were divided into RAPN group (43 cases) and LPN group (24 cases) based on the surgical approach. The RAPN group had a higher R.E.N.A.L. score than the LPN group [(8.7±1.5) vs. (7.9±1.7), P=0.042]. There were no statistically significant differences between the two groups in terms of age [(57.4±10.2) years old vs. (60.9±9.8) years old, P=0.185], body mass index (BMI) [(25.7±3.5) kg/m 2 vs. (25.1±3.6) kg/m 2, P=0.518], and preoperative serum creatinine [(102.9±31.6) μmol/L vs. (102.3±22.4) μmol/L, P=0.930]. Twelve cases underwent hypothermic treatment during surgery, with 9 cases(20.9%) in the RAPN group and 3 cases(12.5%) in the LPN group( P=0.596). Surgical time, intraoperative warm ischemia time, intraoperative blood loss, postoperative fasting time, perioperative complication rate, postoperative serum creatinine, and other indicators were compared between the two groups. Multiple linear regression analysis was used to identify factors affecting postoperative serum creatinine. Kaplan-Meier curves were employed to analyze patient prognosis, and log-rank tests were performed to compare the differences between the two groups. Multiple Cox regression analysis was used to identify factors influencing patient prognosis. Results:All surgeries were completed successfully with negative pathological margins. There were no statistically significant differences between the RAPN and LPN groups in terms of surgical time [(136.6±47.6) min vs. (125.3±34.4) min, P=0.311], intraoperative ischemia time [23.0 (16.0, 30.0) min vs. 19.0 (13.5, 27.5) min, P =0.260], intraoperative blood loss [50.0 (50.0, 100.0) ml vs. 50.0 (22.5, 100.0) ml, P=0.247], postoperative hospital stay [(6.6±3.5) days vs. (7.7±4.2) days, P=0.244], time to drain removal [4(3, 5) days vs. 5(3, 6) days, P =0.175], postoperative fasting time [(2.1±0.7) days vs. (2.2±1.0) days, P=0.729], perioperative complication rate [18.6% (8/43) vs. 16.7% (4/24), P=1.000], postoperative serum creatinine [145.2 (128.3, 191.3) μmol/L vs. 157.8 (136.2, 196.3) μmol/L, P =0.229], and pathological staging [T 1a/T 1b/T 2a/T 3a/T 4 stage: 32/7/1/3/0 case vs. 17/5/0/1/1 case, P=0.804]. Kaplan-Meier survival curves showed that the total survival rates at 1, 3, and 5 years after surgery were 94.7%, 84.9%, and 84.9% for the RAPN group, and 100.0%, 95.5%, and 95.5% for the LPN group, with no statistically significant difference in the log-rank test ( P=0.116). Excluding 10 patients with preoperative tumor metastasis (7 in the RAPN group and 3 in the LPN group), the progression-free survival rates at 1, 3, and 5 years after surgery were 84.8%, 81.1%, and 81.1% for the RAPN group, and 100.0%, 95.0%, and 90.0% for the LPN group, with no statistically significant difference in the log-rank test ( P =0.142). Multiple linear regression analysis showed that the use of hypothermic treatment during surgery significantly reduced postoperative serum creatinine ( B=-72.191, P=0.048). Multiple Cox regression analysis revealed that BMI ( HR=0.743, P=0.044), pathological T stage ( HR=4.235, P=0.018), and preoperative metastasis ( HR=18.829, P=0.035) were independent factors affecting patient overall survival time. A smaller BMI, higher pathological stage, and preoperative metastasis were associated with poorer prognosis. Conclusions:Despite the higher R. E.N.A.L. score and greater surgical difficulty in the RAPN group, RAPN achieved similar perioperative and prognostic results as the LPN, indicating RAPN advantages in treating tumors in isolated kidney. Appropriate intraoperative hypothermic treatment can better protect postoperative renal function. BMI, pathological T stage, and preoperative metastasis are independent factors affecting overall survival time.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Objective:To explore clinical application effect of green channel management mode based on first-aid ef-ficiency and safety indicators on patients with cardiac arrest.Methods:Emergency data of 120 patients with cardiac arrest treated in our hospital from Jan 2021 to Dec 2022 were retrospectively analyzed.Patients undergoing tradi-tional first-aid management from Jan to Dec 2021 were enrolled in traditional group,and those underwent green channel management from Jan to Dec 2022 were included in green channel group,with 60 cases in each group.Se-cure success rate,emergency efficiency and incidence of adverse events were compared between two groups.All pa-tients were followed up for six months after discharge,and incidence rate of major adverse cardiovascular events(MACE)was compared between two groups.Results:Compared with the control group,there was significant rise in success rate of first-aid(75.00％vs.91.67％),x2=6.000,P=0.014;and significant reductions in transport time[(9.06±0.59)min vs.(5.38±0.43)min],auxiliary examination time[(34.03±1.10)h vs.(23.55±0.87)h],emergency room retention time[(3.78±0.15)h vs.(1.67±0.09)h]and operation time[(10.19±0.70)h vs.(7.71±0.29)h]in the green channel group(P=0.001 all).Compared with control group,there were signifi-cant reductions in incidence rates of adverse events(20.00％vs.3.64％)and MACE during the 6-month follow-up(17.78％vs.3.64％)in green channel group(P＜0.05 both).Conclusion:Green channel service process inter-vention can significantly improve secure success rate and emergency efficiency,reduce incidence rates of adverse e-vents and prognosis major adverse cardiovascular events in patients with cardiac arrest,which is worthy of promo-tion and application.

This study systematically analyzed the current status of outcomes in randomized controlled trial(RCT) of traditional Chinese medicine(TCM) treatment of diabetic kidney disease(DKD), aiming to provide a reference for constructing the core outcome set(COS) of TCM treatment of DKD. The clinical RCTs of TCM treatment of DKD that were published from January 2019 to March 2024 were retrieved from seven databases: CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, and Web of Science. The risk of bias was assessed and outcome indicators were qualitatively analyzed. A total of 323 RCTs were included, reporting 199 outcome indicators with the frequency of 3 744 in seven indicator domains: TCM syndromes(196 times, 5.24%), symptoms and signs(275 times, 7.35%), physical and chemical examinations(2 820 times, 75.32%), safety events(422 times, 11.27%), long-term prognosis(21 times, 0.56%), quality of life(9 times, 0.24%), and economic evaluation(1 time, 0.02%). The three most frequently applied outcome indicators were total clinical response rate(268 times, 82.97%), serum creatinine(251 times, 77.71%), and urea nitrogen(206 times, 63.78%). The outcomes in the studies of TCM treatment of DKD had the limitations of high risk of bias, lack of standardization of TCM syndromes and efficacy evaluation, neglect of endpoint indicators, large differences in endpoint indicators and time points of measurement, unclear primary and secondary outcomes, few application of long-term prognosis, quality of life, and economic indicators, and insufficient reporting of safety events. In the future, efforts should be made to actively promote the construction of COS in the studies about the TCM treatment of DKD and enhance the quality of the clinical studies.

Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.
