ObjectiveTo investigate the effects of Jianpi Qinghua granules on blood glucose fluctuations in patients with newly diagnosed overweight/obese type 2 diabetes mellitus （T2DM） and Qi-Yin deficiency syndrome from the perspective of skeletal muscle mass and function， while providing new insights for the treatment of diabetes. MethodsThis study employed a randomized， double-blind， placebo-controlled design. A total of 110 newly diagnosed overweight/obese T2DM patients meeting the inclusion criteria were randomly assigned to either the traditional Chinese medicine （TCM） group （54 cases） or the control group （56 cases）. Patients in the TCM group received Jianpi Qinghua Granules， while those in the control group received a placebo. Both groups underwent dietary and exercise guidance. After 12 weeks of intervention， blood glucose fluctuations were assessed using the following parameters： time in the target blood glucose range （TIR）， mean daily blood glucose （MBG）， standard deviation of mean daily blood glucose （SDBG）， mean amplitude of glycemic excursions （MAGE）， coefficient of variation of blood glucose （CV）， glycated hemoglobin （HbA1c） achievement rate， fasting plasma glucose （FPG）， and 2 hour postprandial glucose （2 hPG）. Skeletal muscle mass was measured by dual-energy X-ray absorptiometry （DXA）， while skeletal muscle function was evaluated using a handheld dynamometer for distal muscle strength and a 5-time sit-to-stand test for lower limb function. Additionally， pancreatic islet function and TCM syndrome scores were analyzed. ResultsNo significant differences were observed in baseline data between the two groups before intervention， ensuring comparability. After treatment， compared to the control group， the TCM group showed a significant increase in TIR （P<0.01）. While the SDBG and CV decreased， and MBG and MAGE increased in the TCM group， these differences were not statistically significant. Notably， the TCM group exhibited significant reductions in 2 hPG （P<0.01） and HbA1c （P<0.05）， though the decrease in FPG was not statistically significant. The HbA1c achievement rate in the TCM group was significantly higher than that in the control group （χ²=45.498， P<0.01）. In terms of skeletal muscle mass and function， the TCM group demonstrated a significant increase in handgrip strength （P<0.01） and a significant reduction in the 5-time sit-to-stand duration （P<0.05）. However， although body fat percentage increased， leading to a decrease in skeletal muscle mass and the ratio of skeletal muscle to fat， these changes were not statistically significant. For pancreatic islet function， the TCM group showed significant reductions in fasting insulin （FINS） and homeostasis model assessment of insulin resistance （HOMA-IR） （P<0.01）. Additionally， the TCM syndrome score in the TCM group was significantly reduced （P<0.01）. ConclusionJianpi Qinghua granules may reduce blood glucose fluctuations in newly diagnosed overweight/obese T2DM patients with Qi-Yin deficiency syndrome by enhancing skeletal muscle function， improving pancreatic islet function， and ameliorating related TCM syndromes.

The research and development of innovative drug have progressed remarkably, but the long development circle and high failure rate have become the bottleneck. Drug repurposing, discovering new indications of approved drugs, is a strategy to overcome these obstacles. By exploring new indications for approved drugs, rapid progress has been made in basic research and clinical translation in recent years. Rich resources of drugs, proven security, efficient development workflow and reduced cost are core advantages of this strategy, making the strategy a crucial direction of optimizing the pipeline of drug research and development. This review systematically summarizes drug repurposing cases that have received clinical approval over the past five years, and proposes core strategies for drug repurposing, including approaches based on targets, pathways, drug similarity, post-treatment phenotypes, and clinical side effects, aiming to provide some strategic guidance for drug repurposing efforts.

AIM: To investigate the association between dyslipidemia and macular hard exudates(HEs)in non-proliferative diabetic retinopathy(NPDR)secondary to type 2 diabetes mellitus(T2DM).METHODS: NPDR patients attending the outpatient ophthalmology clinic from January 2021 to December 2023 were selected and divided into three groups according to the severity of macular HEs. Group A: None or minimal HEs; Group B: Definite HEs; Group C: Prominent HEs. Total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), lipoprotein(a)[Lp(a)] levels and other lipid-related indicators were routinely measured. The correlation between these indicators and HEs was analyzed.RESULTS:Group A(24 eyes)consisted of 9 males and 15 females with the mean age of 54.71±6.15 y, group B(52 eyes)consisted of 20 males and 32 females with the mean age of 55.08±6.27 y, group C(14 eyes)consisted of 9 males and 5 females with the mean age of 53.93±6.08 y. The concentration of TC, TG, LDL-C and Lp(a)was highest in group C, followed by group B and lowest in group A with statistically significant differences(P<0.001). There were no statistically significant differences between the three groups for fasting plasma glucose(FPG), glycated hemoglobin A1c(HbA1c), creatinine(Cr), and HDL-C(P>0.05). The results of multivariate Logistic regression analysis showed that elevated levels of TC, TG, LDL-C, and Lp(a)were associated with the presence of macular HEs. Receiver operating characteristiccurve analysis showed that the area under the curve(AUC)for TC, TG, LDL-C, Lp(a), and their combination in predicting macular HEs in NPDR were 0.785, 0.718, 0.784, 0.742, and 0.911, respectively, with the combined model demonstrating the highest predictive performance.CONCLUSION: Dyslipidemia is closely associated with the development and progression of macular HEs in patients with NPDR and T2DM. The levels of TC, TG, LDL-C, and Lp(a)were correlated with the severity of macular HEs, suggesting that dyslipidemia may be involved in the pathological process of macular HEs formation.

Bronchopulmonary dysplasia（BPD）is a chronic respiratory disease characterized by developmental disorders and abnormal repair of lung tissue in premature infants.Its clinical manifestations are characterized by persistent respiratory distress syndrome，which can cause progressive lung function damage and significantly affect the quality of life and long-term prognosis of the affected children.Vitamin D has been proven to have multiple lung protective effects in recent years.It not only participates in regulating normal lung development，but also effectively inhibits inflammatory reactions，promotes the biosynthesis of pulmonary surfactant，regulates cell apoptosis，and maintains lung tissue function and structural integrity.The above physiological functions are significantly correlated with the pathophysiology of BPD，providing a new theoretical perspective for further elucidating the pathogenesis of BPD.Based on existing evidence，vitamin D may provide new treatment and research directions for BPD.

Objective:To evaluate the association between triglyceride-glucose(TyG) index level, their variability, and the risk of incident hyperuricemia(HUA).Methods:A total of 1 583 cases with good compliance who underwent follow-up at the health examination center of a tertiary hospital physical in Zhengzhou were enrolled. The TyG index mean(TyG-mean) and variability indexes, including standard deviation(TyG-SD), coefficient of variation(TyG-CV), and adjusted standard deviation(adj-TyG-SD), were calculated based on TyG index values from three consecutive annual health check-ups. Cox proportional risk regression model was used to assess the relationship between the variability of TyG index and the risk of new-onset HUA; the dose-response relationship between different TyG indexes and HUA was examined using restricted cubic spline(RCS). Results:After a 3-year follow-up, 146 participants developed incident HUA. Both TyG-mean and TyG index variability indicators were significantly higher in the HUA group compared to the non-HUA group( P<0.05). After adjusting for multiple confounders, each standard deviation σincrease in TyG-SD, TyG-CV, and adj-TyG-SD was associated with a 1.23-fold(95% CI 1.06-1.43), 1.22-fold(95% CI 1.05-1.42), and 1.26-fold(95% CI 1.08-1.45) higher risk of incident HUA, respectively. RCS analysis revealed a nonlinear association between adj-TyG-SD and HUA risk( P<0.05), with a critical threshold of 0.55 at a hazard ratio( HR) of 1. Conclusions:Increased TyG index variability is associated with a higher risk of incident HUA, with adj-TyG-SD showing the strongest correlation with HUA risk.

Objective:To investigate the clinical results of anteriorly displaced orbicularis oculi flap and autologous granular fat injections via sub-brow incision for correction of different degrees of sunken upper eyelid.Methods:From September 2021 to September 2022, a total of 80 patients with upper eyelid skin laxity and sunken upper eyelid were recruited prospectively from the Department of Plastic Surgery, Jiangsu Province Hospital of Chinese Medicine. There were 18 males and 62 females, aged 28 to 60 years, with a mean age of (42.7±9.2) years. According to Park's method, 59 patients with grade Ⅰ and grade Ⅱ sunken upper eyelid were treated with eyebrow lifting and orbicularis oculi flap correction, and 21 patients with grade Ⅲ upper eyelid sunken were treated with eyebrow lifting combined with autologous particles fat filling. The patients were followed up for 6 months. The depth of sunken upper eyelid was measured before and after operation. The incidence of adverse reactions and patient satisfaction were recorded.Results:The mean depth of depression measured preoperatively was (6.01±2.25) mm in the grades Ⅰ and Ⅱ sunken upper eyelid, which was improved to (2.00±1.06) mm at the 6-month postoperative follow-up ( P=0.001), and the mean depth of depression was (13.15±1.75) mm in the group of grade Ⅲ, which was improved to (4.15±1.49) mm at the 6-month postoperative follow-up ( P=0.001). After 6-month follow-up, the incidence of complications was 6.3% (5/80) and the satisfaction rate was 90.0% (72/80). Conclusions:Different correction methods should be chosen according to the degree of sunken upper eyelid. Grades Ⅰand Ⅱ sunken upper eyelid are corrected with orbicularis muscle flap through sub-eyebrow incision, and grade Ⅲ is corrected with autologous fat injection. Both the clinical effect and patient satisfaction rate are higher.

Objective:To evaluate the clinical efficacy and safety of fractional CO 2 laser combined with topical application of radix scutellariae ointment in the treatment of hyperplastic scar. Methods:This randomized controlled trial prospectively enrolled 90 patients with hyperplastic scar treated with fractional CO 2 laser at the Affiliated Hospital of Nanjing University of Chinese Medicine (Jiangsu Province Hospital of Chinese Medicine) from January 2020 to December 2021. Participants were randomly divided into a trial group and a control group using a random number table. The trial group ( n=45, 22 males, 23 females, aged 18-54 years) received topical radix scutellariae ointment post-laser treatment, while the control group ( n=45, 23 males, 22 females, aged 19-55 years) received recombinant bovine basic fibroblast growth factor gel. Both groups underwent treatment every 3 months, with scar assessments conducted at 1-month post-treatment. Outcomes included Vancouver scar scale (VSS) scores, scar cosmesis assessment and rating (SCAR) scores, adverse reaction rates, and patients' satisfaction. Results:After the first, second, and third treatments, the trial group showed significantly lower VSS and SCAR scores compared to the control group (all P<0.05). Patients' satisfaction in the trial group was 91.1% (41/45), significantly higher than 77.8% (35/45) in the control group ( P=0.036). The adverse reaction rate in the trial group was 15.6% (7/45), and 28.9% (13/45) in the control group, there was no statistical difference ( P=0.813). Conclusion:Fractional CO 2 laser combined with topical radix scutellariae ointment demonstrate superior clinical efficacy, higher patient satisfaction, and lower adverse reaction rates in the treatment of hyperplastic scar.

Objective:To investigate the clinical efficacy of autologous ear cartilage biomimetic nasal tip framework construction combined with dermal fat dorsal grafting in rhinoplasty.Methods:A retrospective analysis was conducted on clinical data of patients who underwent rhinoplasty at the Department of Plastic Surgery, Affiliated Hospital of Nanjing University of Chinese Medicine from June 2021 to May 2023. Autologous ear cartilage with preserved perichondrium was harvested from patients, and fashioned into a nasal tip framework simulating the natural nasal tip structure. Dermal fat grafts were harvested from the lateral gluteal crease region where the dermis was thicker, and implanted into the nasal dorsum for augmentation rhinoplasty. Postoperative follow-up included observation of incision healing, nasal tip morphology, and complications. Pre- and postoperative photographs were taken to measure nasal length and nasal tip height. Ultrasound was used to measure subcutaneous fat thickness at the nasal root before and after surgery, and absorption rates were calculated. The absorption rate at 6, 12, and 24 months postoperatively = (1 -subcutaneous fat thickness at 6 or 12 or 24 months postoperatively/subcutaneous fat thickness at 1 month postoperatively) × 100%. Aesthetic satisfaction was evaluated based on surgeon assessment, patient self-evaluation, and third-party physician evaluation (satisfaction by all three parties was rated as markedly effective, by two parties as effective, by one party as fair, and by none as poor). The aesthetic satisfaction rate = (markedly effective + effective) cases/total cases × 100%. Comparisons of preoperative and postoperative nasal tip height and nasal length were performed using paired t-tests, with P<0.05 considered statistically significant. Comparisons of subcutaneous fat thickness at the nasal root at different time points and absorption rates at different postoperative time points were performed using repeated measures ANOVA, with post-hoc pairwise comparisons using Bonferroni correction. For subcutaneous fat thickness comparisons, P<0.007 was considered statistically significant; for absorption rate comparisons, P<0.017 was considered statistically significant. Results:A total of 38 patients were included, consisting of 5 males and 33 females, with a mean age of 29.42 years (range 20-38 years). All patients were followed up for 24 months postoperatively. All incisions healed well; nasal appearance was aesthetically pleasing; nasal dorsal height was satisfactory; nasal tip mobility was good; the framework was stable; and no complications occurred. At 24 months postoperatively, nasal tip height [(22.87±0.52) mm vs. (19.94±0.53) mm] and nasal length [(47.18±0.61) mm vs. (44.20±0.55) mm] were significantly increased compared to preoperative measurements (both P<0.01). Comparison of subcutaneous fat thickness at the nasal root between preoperative and postoperative time points (1, 6, 12, and 24 months) showed statistically significant differences ( P<0.007). Post-hoc comparisons revealed statistically significant differences between: postoperative 1 month and 6 months vs. preoperative; postoperative 12 months vs. postoperative 1 and 6 months; and postoperative 24 months vs. postoperative 1 and 6 months (all P<0.007). However, the comparison between postoperative 24 months and 12 months showed no statistically significant difference ( P>0.007). Comparison of absorption rates at postoperative time points (6, 12, and 24 months) showed statistically significant differences ( P<0.017). Comparisons between postoperative 12 months vs. 6 months, and postoperative 24 months vs. 6 months showed statistically significant differences (both P<0.017), while the comparison between postoperative 24 months and 12 months showed no statistically significant difference ( P>0.017). In the aesthetic satisfaction survey, 37 cases were markedly effective and 1 case was fair, achieving an aesthetic satisfaction rate of 97%. Conclusion:The use of autologous ear cartilage for constructing a biomimetic nasal tip framework combined with dermal fat dorsal grafting in rhinoplasty results in natural postoperative appearance and high patient satisfaction, demonstrating significant value for extensive clinical use.
