Objective:To analyze the characteristics of Fournier gangrene (FG) induced by sodium-glucose cotransporter 2 inhibitors (SGLT2i), and provide reference for clinical safe drug use.Methods:CNKI, Wanfang Med Online, VIP, PubMed, Web of Science and other databases (up to January 2024) were retrieved and clinical data on patients with FG associated with the 5 kinds of SGLT2i currently used in clinical practice in China were collected and descriptively analyzed, including gender, age, comorbidities, concomitant medications, onset time and clinical manifestations of SGLT2i-related FG, laboratory and imaging examination results, treatment and outcomes, etc.Results:A total of 15 documents were included in the analysis, involving 15 patients, with 12 males and 3 females. The age of these patients ranged from 34 to 72 years, with 11 cases being over 50 years. Dapagliflozin was used in 7 cases, empagliflozin in 6 cases, canagliflozin in 2 cases, and no related reports on ertugliflozin and henagliflozin were collected. The main clinical manifestations of the 15 patients were redness, swelling, pain, abscess or purulent discharge in perineum, scrotum and perianal, etc. The time from application of SGLT2i to onset of FG ranged from 1 month to 6 years. Wound secretion bacterial culture was performed in 10 patients, and the results were all positive, including 9 cases of bacterial infection and 1 case of mixed infection of bacteria and fungi. All 13 patients who underwent imaging examinations had imaging manifestations related to FG. SGLT2i were discontinued in all patients. After treatments with broad-spectrum antibiotics and surgery, 14 cases were improved and 1 case was cured.Conclusions:SGLT2i has the risk of causing FG, which is more common in males. The clinical use of SGLT2i should be monitored closely. Secretion culture and imaging examination are helpful for the diagnosis of FG. The patient′s prognosis is good after discontinuation of medication, symptomatic treatment, and surgery.

Objective:To summarize Chinese materia medica with estrogen-activity based on data mining and analyze their characteristics.Methods:Literature was retrieved from CNKI, Wanfang Data, Chongqing VIP, CBM, PubMed and Web of Science from the establishment of the databases to June 30, 2024, and Chinese materia medica with estrogenic activity were screened. Excel 2021 and KH Coder 3.0 software were used to perform statistical and network co-occurrence analysis on the efficacy classification of Chinese materia medica, properties, tastes and meridians, screening methods for estrogen activity, and applications.Results:Totally 121 kinds of Chinese materia medica with estrogen-activity were included in total. The efficacy classifications were mostly tonic medicines, heat-clearing medicines and blood circulation promoting drugs. The properties were mainly warm and neutral, the tastes were mainly sweet and bitter, and the meridians were mainly the liver, kidney and spleen meridians. The network co-occurrence analysis of the efficacy classification, properties, tastes and tropism meridians showed that the clustering relationship of tonic medicine-neutral-sweet-liver-kidney was the most obvious. The screening methods mainly included MCF-7 cell proliferation and uterine weight gain experiments. Their applications mainly covered osteoporosis, perimenopausal syndrome, lipid metabolism disorder, and premature ovarian failure, etc.Conclusions:Chinese materia medica with estrogen-activity or their components act on estrogen target cells or organs to exert estrogen-like or antagonistic estrogenic effects. This kind of Chinese materia medica can regulate the body's qi, blood, yin and yang, the function of organs and the fullness of Tiangui, as well as the Chong meridian and Conception Vessel, thus improving human growth and development, reproduction and aging. In the future, it is suggested to explore their effective components, mechanisms, bidirectional effect and safety on the basis of guiding clinical medication with the theory of TCM, combining with modern medical research techniques and evidence-based medical research.

The theory of yin-yang is a foundational concept in traditional Chinese medicine (TCM) and has been refined through millennia of clinical practice and theoretical development. This theory remains central to syndrome differentiation and therapeutic decision-making. With rapid advances in modern biomedicine and information sciences, this review synthesizes recent interdisciplinary progress linking yin-yang concepts to cellular metabolism, redox balance, gene regulation, and immunomodulation. We outline how pathological states historically described as “yin deficiency” or “yang hyperactivity” correspond to alterations in cellular energy conversion, molecular signaling networks, and systemic homeostasis, and we critically evaluate current evidence for mechanistic pathways. Notwithstanding promising correlations, major gaps persist in mechanistic clarity and the establishment of quantitative metrics, limiting the rigorous integration of yin-yang theory into evidence-based frameworks. To address these gaps, we propose a research roadmap that leverages modern biotechnology, mathematical modeling, and artificial intelligence for quantitative multiscale analysis. By integrating molecular, cellular, and systemic datasets, this approach can clarify the biological connotations of yin-yang balance for physiology, disease mechanisms, and clinical outcome assessment.

Objective To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE)intervention timing and liver injury periodization in patients with exertional heat stroke(EHS).Methods Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected,then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT,AST,TBIL and DBIL.According to propensity score matching analysis,11 patients in the survival group and 12 patients in the death group were included in the statistical analysis,and 20 of them were treated with TPE.The changes in indicators and clinical outcomes before and after TPE were observed,in order to evaluate the impact of intervention timing on prognosis.Results Among the 23 patients,14 had no liver injury or could progress to the repair phase,resulting in 3 deaths(with the mortality rate of 21.43%),while 9 patients failed to pro-gress to the repair phase,resulting in 9 deaths(with the mortality rate of 100%),with significant differences(P＜0.05).The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13),while that of interven-tion after reaching or exceeding the third stage was 85.71%(6/7),and the difference was statistically significant(P＜0.05).Conclusion TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes,thereby improving prognosis and reducing mortality.

Objective: To assess the efficacy and safety of combining traditional Chinese medicine (TCM), specifically Chinese herbal medicine (CHM), with Western medicine (WM), compared to WM alone to treat breast cancer endocrine therapy-related osteoporosis (BCET-OP) by meta-analysis. Methods: Thirty-eight randomized controlled trials involving 2170 participants were analyzed. Eight databases were searched for articles published between inception and December 2023. Quality assessment was performed using the Risk of Bias 2 tool. Results: Significant increases were observed in the TCM-WM group in lumbar vertebrae bone mineral density (BMD) (P < .001, mean difference (MD) = 0.07, 95% confidence interval (CI): 0.06 to 0.08), lumbar vertebrae T-score (P = .0005, MD = 0.21, 95%CI: 0.09 to 0.33) and collum femoris BMD (P = .01, MD = 0.10, 95%CI: 0.02 to 0.19). No significant difference was observed between the groups in the collum femoris T-score and estradiol levels. Bone gla-protein levels were significantly increased in the TCM-WM group (P = .0002, MD = 0.52, 95%CI: 0.25 to 0.79). Beta-CrossLaps decreased significantly in the TCM-WM group (P = .0008, MD = −0.10, 95%CI: −0.16 to −0.04). No significant difference was observed between the TCM-WM and WM groups in alkaline phosphatase, in procollagen type I N-terminal propeptide, and in the Kupperman index. The visual analog score (VAS) was decreased in the TCM-WM group compared to the WM group (P < .001, MD = −1.40, 95%CI: −1.94 to −0.87). No significant difference in adverse events was observed between the two groups. Conclusion Combining CHM with WM in patients with BCET-OP significantly improved BMD, T-score, and certain bone turnover markers and reduced the VAS score, indicating potential benefits for bone health and related pain. Adverse event analysis revealed no differences between the groups, supporting the feasibility of the combination therapy. However, further research, particularly in diverse populations, is required.

Objective:To establish a prescription pre-audit system based on the structure-process-outcome (SPO) model in the the Affiliated Hospital of Qingdao University and explore its application effect.Methods:Based on the structural dimension of SPO model, the organizational structure, pharmaceutical team, management system of pharmaceutical prescription audit, and audit environment of the prescription pre-audit system were established. Based on the process dimension of SPO model, the pre-audit process, medication knowledge base, and audit rule base were established, quality monitoring and control were implemented, and relevant personnel training were conducted. Based on the outcome dimension of SPO model, the review rate, manual review rate, clinician acceptance rate of prescription review, reasonable rate of outpatient and emergency prescription comments, and intervention rate of inpatient medical order were verified after the prescription pre-audit system application.Results:The prescription pre-audit system was first launched in the main hospital area of the Affiliated Hospital of Qingdao University in March 2021, and achieved full coverage in all five hospital areas by May 2023. The review rates of outpatient and emergency prescriptions and inpatient medical orders had been increasing year by year from 2021 to 2023, and all reached more than 99% of the expected rates in 2023. Compared with 2021, the proportions of outpatient and emergency prescriptions and inpatient medical orders submitted to manual review decreased in 2023 [1.2% (112 206/9 509 430) vs. 2.9% (16 214/549 672), 2.9% (206 258/7 152 620) vs. 3.9% (147 679/3 814 929), the proportions of prescriptions that failed to be reviewed in time decreased [0.7% (62 382/9 509 430) vs. 1.4% (7 429/549 672), 0.3% (22 816/7 152 620) vs. 2.2% (83 303/3 814 929)], and the acceptance rates of outpatient and emergency prescription review and inpatient medical orders review by clinicians increased [76.1% (2 421/3 180) vs. 57.0% (339/595), 94.3% (1 000/1 060) vs. 70.7% (797/1 128)], with statistically significant differences (all P<0.001). But there were still some prescriptions and orders that needed manual review but were not reviewed in time and finally missed review. Compared with 2021, the reasonable rates of outpatient and emergency prescription comments increased in 2023 [96.7% (924 558/956 252) vs. 92.2% (983 827/1 067 357), 98.7% (518 307/525 227) vs. 98.0% (181 296/185 069)], and the intervention rate of inpatient medical orders decreased [0.7% (196 522/26 751 992) vs. 0.9% (195 660/22 631 289)], with statistically significant differences (all P<0.001). Conclusions:Applying the SPO model can improve the organization and management of the prescription pre-audit system, and ensure the smooth launch and safe operation of the system. After verification, the operating speed of the prescription pre-audit system and prescription review speed of pharmacists could basically meet the clinical needs, the indicators of rational drug use in the hospitals were improved, and the professional and technical ability of pharmacists were enhanced.

Objective: To analyze dental caries and associated factors among primary and middle school students in Henan Province, so as to provide reference for dental caries prevention and control. Methods: The data of physical health survey of students in Henan Province in 2019 was analyzed for caries and other related index of students aged 7, 9, 12, 14 years. Chi square test was used to compare detection rate of caries by sex and residence, analysis of variance was used to compare the height between with and without risk of caries, and Logistic regression analysis was conducted for the influencing factors of caries. Results: The caries rate was 56.6%. And the male students (53.4%) was lower than the female students (59.7%). The urban students (53.4%) was lower than the rural students (59.8%)( χ 2=52.31,54.00, P <0.01). The height of the caries free group was higher than that of the caries group, and the height difference was 0.5-1.6 cm; the prevalence of caries decreased with the increase of age( χ 2=992.01, P < 0.01 ). The detection rate of anemia in caries group (16.7%) was higher than that in caries free group (14.9%)( χ 2=7.98, P <0.01). Multivariate Logistic regression analysis showed that age ( OR =0.82) gender ( OR =1.27) urban area and rural ( OR =1.26) overweight ( OR =0.67) and obesity ( OR = 0.67 ) were all influencing factors of dental caries( P <0.01). Conclusion Dental caries is high among primary and middle school students in Henan Province, and dental caries affects their growth, development and nutritional status, and the prevention and control measures of dental caries among primary and middle school students should be strengthened.

Objective:To investigate the clinical effect on ultrasound-guided vascular access-interventional therapy of hemodialysis in day surgery mode.Methods:Hemodialysis patients with vascular access dysfunction who underwent ultrasound-guided interventional therapy in the First Affiliated Hospital of Xi'an Jiaotong University from September 1, 2018 to October 31, 2020 were retrospectively analyzed. Demographic and clinical data were collected by electronic medical record system and telephone follow-up. Kaplan-Meier method was used to analyze the patency rate of vascular access.Results:A total of 421 cases of ultrasound-guided vascular access intervention were performed in 269 patients. The technical success rates of stenosis, chronic occlusion and acute occlusion lesion were 98.8%, 90.6% and 86.4%, respectively, and 406 cases (96.4%) of 246 patients were clinically successful. The postoperative brachial artery blood flow was 821(627, 1 029) ml/min, which was significantly higher than 309(202, 453) ml/min before the operation ( Z=-13.547, P<0.001). No serious complications occurred during and after the operation. At 6, 12, 18 and 24 months after operation, the primary patency rate was 74%, 59%, 48% and 45%, respectively, the assisted primary patency rate was 94%, 91%, 88% and 82%, and the secondary patency rate was 96%, 93%, 91% and 86%. Compared with the conventional inpatient surgery mode, the total cost of the day surgery mode was significantly reduced [12 067(10 051, 13 198) yuan vs 14 986(12 411, 20 643) yuan, Z=-13.185, P<0.001], and the hospital stay was significantly shortened [5.1(3.5, 6.9) h vs 73.4(31.6, 146.6) h, Z=-13.348, P<0.001]. Conclusion:It is safe and effective to perform interventional therapy for vascular access malfunction under ultrasound in day surgery mode, which can save cost and time of hospitalization, and can be carried out in hospitals with relevant conditions.
