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).

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

Metabonomics and proteomics were employed to investigate the mechanism of Yuzhi Zhixue Granules in treating polycystic ovary syndrome with insulin resistance(PCOS-IR). The disease model was established by feeding a high-fat diet and gavage of letrozole solution and it was then treated with different doses of Yuzhi Zhixue Granules. The therapeutic effect of Yuzhi Zhixue Granules was evaluated based on the body mass, homeostasis model assessment of insulin resistance and insulin sensitivity index, serum levels of adipokines, and histopathological changes of rats. Metabolomics and proteomics were employed to find the action pathways of Yuzhi Zhixue Granules. The results showed that Yuzhi Zhixue Granules reduced the body mass, improved the insulin sensitivity and aromatase activity, improved the levels of leptin, adiponectin and other adipokines, and alleviated insulin resistance, histopathological changes, and metabolic disorders in PCOS-IR rats. Metabolomics results revealed 14 metabolites with altered levels in the ovarian tissue, which were closely related to glutathione metabolism and pyruvate metabolism. Proteomics results showed that the therapeutic effect of Yuzhi Zhixue Granules was mainly related to the adipokine, adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK), phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt), forkhead box protein O(FoxO), and mechanistic target of rapamycin(mTOR) signaling pathways. Western blot results showed that compared with the model group, Yuzhi Zhixue Granules treatment decreased the p-AMPK/AMPK and p-FoxO1/FoxO1 levels, increased the p-mTOR/mTOR level, and up-regulated the expression level of recombinant glucose transporter 4(GLUT4). Yuzhi Zhixue Granules can balance amino acid metabolism and pyruvate metabolism by regulating the AMPK/mTOR/FoxO/GLUT pathway to maintain the homeostasis of the ovarian environment and alleviate insulin resistance, thus treating PCOS-IR.

Objective To evaluate the management and indicators of pathogen detection before antimicrobial treat-ment for inpatients in second level and above medical institutions(MIs)in Guangdong Province,and provide direc-tion and decision-making basis for the improvement of pathogen detection quality in the region.Methods The ma-nagement status,information system functions,and pathogen detection rate indicators of secondary and above MIs in 21 cities in Guangdong Province was surveyed through online questionnaire surveys and system submission.A baseline survey on sentinel monitoring MIs was conducted from July 15th to August 8th,2023.From November 7th to 30th,a baseline survey on non-sentinel monitoring MIs was launched.Surveys on indicator information of all MIs were completed from January 15th to 30th,2024.Results A total of 265 MIs were surveyed,and the proportions of establishing special working groups(83.98％),developing special action improvement plans(79.01％),estab-lishing pathogen detection rate management systems(91.71％),and developing management assessment plans(76.80％)of tertiary MIs were all higher than that of secondary MIs,differences were all statistically significant(all P＜0.05).The proportion of tertiary MIs with various information system functions was higher than that of secondary MIs(all P＜0.05).The pathogen detection rate(61.07％)before antimicrobial treatment and health-care-associated infection(HAI)diagnosis-related pathogen detection rate(88.00％)of inpatients in tertiary MIs were both higher than those in secondary MIs(both P＜0.05).Among different types of MIs,pathogen detection rate before antimicrobial treatment of inpatients in maternal and child health MIs was higher than that in other types of MIs.HAI diagnosis-related pathogen detection rate in other specialized hospitals was the highest,and pathogen detection rate before combined use of key antimicrobial treatment in traditional Chinese medicine hospitals was the lowest,differences were all statistically significant(all P＜0.05).Conclusion Tertiary MIs have more advantages in management strategies and information technology construction than secondary MIs,secondary MIs need more guidance and support.Monitoring and analysis of pathogen detection rate indicators in MIs of different levels and types should be strengthened through special actions.

This paper explored the protective effect and potential mechanism of Shouhui Tongbian Capsules(SHTB) on cerebral ischemia-reperfusion rat models. Rats were randomly divided into sham surgery group, model group, low-dose SHTB group(0.2 g·kg~(-1)·d~(-1)), high-dose SHTB group(SHTB g·kg~(-1)·d~(-1)), and an edaravone positive drug group(5.4 mg·kg~(-1)·d~(-1)), with 12 rats in each group. Rats were given continuous intragastric administration seven days before surgery, and the suture method was used to establish the cerebral ischemia-reperfusion injury(CIRI) rat model. Zea-Longa rating scale for neurological functions was used to assess the degree of neurological function impairment in rats; hematoxylin-eosin(HE) staining was used to observe the pathological damage of rats' brain tissue; TTC staining was used to measure the area of cerebral infarction in rats; enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α) in each group. Western blot was used to detect the level of tight junction protein associated with the blood-brain barrier and intestinal barrier, as well as the protein expression of the TLR4/MyD88/NF-κB pathway in brain tissue. Changes in rats' brain tissue and metabolites in serum were detected by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS), so as to explore the potential mechanism of SHTB treatment for CIRI in rats. Compared with the model group, SHTB could significantly alleviate the pathological damage to the brain of CIRI rats, reduce the volume of cerebral infarction, and lower the level of inflammation in the serum; Western blot results showed that SHTB could regulate the expression of tight junction proteins related to the blood-brain barrier and intestinal barrier in CIRI rats and downregulate the expression of TLR4, NF-κB, and MyD88 proteins in brain tissue. The UPLC-MS/MS results indicated that SHTB could significantly regulate the content of potential differential metabolites such as fatty acids, and serum and brain tissue are involved in pathways such as unsaturated fatty acid biosynthesis. SHTB could repair intestinal barrier function, reduce inflammation levels in the body, and improve the damaged blood-brain barrier, exerting a protective effect on brain nerves. Its mechanism may be achieved by balancing fatty acid metabolism and regulating the expression of TLR4/MyD88/NF-κB signaling pathway proteins.

Central precocious puberty secondary to Leydig cell tumors is rare in children. We retrospectively analyzed the mid- to long-term follow-up data of patients with Leydig cell tumors. The clinical data of 12 consecutive patients who were treated at Beijing Children's Hospital, Capital Medical University (Beijing, China), between January 2016 and October 2023 were retrospectively reviewed. Clinical evaluations, including physical examination, hormone examination, serum tumor marker analysis, abdominal and scrotal ultrasound, chest X-ray, and bone age measurement, were conducted before surgery and at follow-up time points. Surgical approaches were selected according to the individual conditions. Patients with an abnormal hormonal status and suspected of having central precocious puberty were referred to endocrinologists to confirm the diagnosis. Subsequently, gonadotropin-releasing hormone analog therapy was proposed. The mean patient age was 81.3 (range: 40-140) months at the time of the operation. Ten patients had peripheral precocious puberty at admission. All patients had elevated preoperative testosterone levels, whereas tumor marker levels were normal. Testis-sparing surgery was performed in eleven patients, and radical orchiectomy was performed in one patient. The follow-up duration (mean ± standard deviation) was 36.2 ± 25.3 months. Five patients had central precocious puberty, with a mean duration of 3.4 (range: 1-6) months postoperatively. Three patients were receiving gonadotropin-releasing hormone analog therapy, and good suppression of puberty was observed. No risk factors were found for secondary central precocious puberty. There was a high prevalence of central precocious puberty secondary to Leydig cell tumors in our study. Gonadotropin-releasing hormone analog therapy has satisfactory treatment effects. Larger sample sizes and long-term follow-up are needed in future studies.

Molecular imprinting is a biomimetic technique that simulates the specific recognition of biological macromolecules such as antibody. Based on molecular imprinting and high-specificity affinity analysis,the biomimetic imprinting affinity analysis (BIA) possesses many advantages such as high sensitivity,strong tolerance,good specificity and low cost,and thus,it has shown excellent prospects in food safety detection,pharmaceutical analysis and environmental pollution monitoring. In this review,the construction methods of recognition interfaces for BIA were summarized,including bulk polymerization,electro-polymerization and surface molecular imprinting. The application of molecularly imprinted polymers in different analysis methods,such as radiolabeled affinity analysis,enzyme-labeled affinity analysis,fluorescence-labeled affinity analysis,chemiluminescence affinity analysis and electrochemical immunosensor was mainly discussed. Furthermore,the challenges and future development trends of BIA in practical application were elucidated. This review might provide new reference ideas and technical supports for the further development of BIA technique.

OBJECTIVE: To study the effect of ultrasound-guided fascia iliaca compartment block on perioperative analgesia and postoperative complications in geriatric patients with hip fractures. METHODS: A total of 127 elderly patients undergoing hip fracture surgery from January 2021 to September 2021 were randomized to receive ultrasound-guided continuous fascia iliaca compartment block(group F) either intravenous analgesia control group(group C). There were 62 cases in group F, including 19 males and 43 females with an average age of (82.4±7.2) years old ranging from 66 to 95 years old, involving 25 femoral neck fractures and 37 femoral intertrochanteric fractures. There were 65 cases in control group, including 18 males and 47 females, with an average age of (81.4±8.7) years old ranging from 65 to 94 years old, involving 29 femoral neck fractures and 36 femoral intertrochanteric fractures. The visual analogue scale(VAS), minimental state examination (MMSE), observer's assessment of alertness/sedation(OAA/S) scale, modified Bromage score, postoperative complications and general conditions during hospitalization in two groups were observed. RESULTS: The resting and exercise VAS at 30 min after block, anesthesia placement and 6, 24 and 48 h after surgery were lower than those in group C(P<0.05). In group F, MMSE scores at 12 h before surgery, and 1, 3 d after surgery and OAA/S scores at 3 d after surgery were higher than those in group C(P<0.05). The incidence of adverse effects and the number requiring additional analgesia were lower than those in group C(P<0.05). Group F had better perioperative analgesia satisfaction and hospital stay than group C(P<0.05). But there was no significant difference regarding Bromage score and 30-day mortality between two group(P>0.05). CONCLUSION Ultrasound-guided continuous fascia iliacus space block was safe and effective for elderly patients with hip fracture, and could significantly reduce perioperative pain, improve postoperative cognitive function, and reduce postoperative complications, thereby shortening hospital stay and improving the quality of life during hospitalization.

5α-reductase 2 deficiency prevents testosterone from being converted to dihydrotestosterone, which causes abnormal urogenital sinus development. The aim of this study was to analyze the relationship between genotype-phenotype, surgical selections, and postoperative complications of 5α-reductase 2-deficient patients with hypospadias. We retrospectively evaluated the medical records of patients who were diagnosed with 5α-reductase 2 deficiency after genetic testing in the Department of Endocrinology and underwent initial hypospadias surgery in the Department of Urology in Beijing Children's Hospital, Capital Medical University (Beijing, China), from April 2007 to December 2021. A total of 69 patients were included in this study; the mean age at surgery was 34.1 months, and the average follow-up time was 54.1 months. Sixty children were treated with preoperative hormone stimulation (PHS) to promote penile growth. The average penis length and glans width were increased by 1.46 cm and 0.62 cm, respectively. The most frequent mutations were p.R227Q (39.1%, 54/138), p.Q6* (15.2%, 21/138), p.G203S (12.3%, 17/138), and p.R246Q (11.6%, 16/138). In 64 patients who were followed up, 43 had a one-stage operation and 21 had a staged operation, and there were significant differences in external masculinization score (EMS) ( P = 0.008) and the average number of operation required to cure ( P < 0.001) between one-stage and staged operations. PHS had a positive effect ( P < 0.001) on penile development. The p.R227Q mutation was associated with higher EMS and less severe hypospadias. One-stage surgery can be selected if conditions permit. The growth and development of children are acceptable in the long term, but penis growth remains unsatisfactory. Long-term complications of hypospadias should be considered during puberty.
