This paper summarizes the clinical experience in the syndrome differentiation and treatment of rosacea using the method of venting heat and resolving stagnation. It is considered that the key pathogenesis of rosacea is the accumulation of heat with stagnation. Accordingly， the method of venting heat and resolving stagnation is proposed， which vents and disperses constraint heat by applying approaches such as dredging defensive qi， clearing qi， venting ying （营） level， and cooling blood， while eliminating stagnation and masses through regulating qi， resolving dampness， dispelling phlegm and removing stasis. In clinical practice， a core prescription for venting heat and resolving stagnation is formulated， with flexible modifications made according to the clinical characteristics of different rosacea subtypes， including erythematotelangiectatic， papulopustular， phymatous， and ocular types， thereby providing therapeutic insights for the treatment of rosacea with traditional Chinese medicine.

Methods: Six finite element models of T12 burst fractures were developed to simulate short-segment stabilization under normal or osteoporotic bone conditions, with/without augmentation screws at the fractured vertebra. Spinal stiffness, implant stresses, and axial displacement/micromotion of the bony defect were measured and compared under mechanical loading. Results: Osteoporotic models exhibited a greater range of motion (ROM) than normal bone. All six-screw constructs reduced ROM across all motions compared with traditional four-screw models. Osteoporotic fracture models gained greater benefit from intermediate screw augmentation at the fracture vertebra, which also lowered axial displacement/micromotion. In six-screw models, rod stress increased while pedicle screw stress decreased. Intermediate screws at fractured vertebrae produced similar changes in stress distribution across all fixation models, regardless of bone quality. Conclusions Our findings may facilitate implant selection for osteoporotic burst fractures, supporting the use of more rigid fixation sixscrew constructs to reduce the risk of mechanical failure and postoperative re-collapse.

Objective To evaluate the efficacy and safety of a combination therapy regimen comprising stereotactic body radiation therapy (SBRT) combined with liposomal irinotecan, camrelizumab, and anti-angiogenic therapy (CAP) in patients with advanced bone and soft tissue sarcomas. Methods This study is a prospective subgroup analysis of the multicenter, open-label, single-arm phase Ⅱ CAP trial (NCT04569916), which enrolled 60 patients with advanced solid tumors who had progressed after standard therapy between November 2020 and February 2023, including 11 patients with advanced bone and soft tissue sarcomas. All patients received sequential liposomal irinotecan within 48 hours after stereotactic body radiotherapy (SBRT), followed by maintenance therapy with camrelizumab and an anti-angiogenic agent until disease progression or intolerable toxicity. The primary efficacy endpoint was objective response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results In the bone and soft tissue sarcoma subgroup (n=11), three patients achieved partial response (PR), five had stable disease (SD), and three experienced disease progression (PD). ORR was 27.3%, and DCR was 72.7%. mPFS was 5.8 months (95%CI: 2.2-10.3), and mOS not reached. Regarding safety, adverse reactions primarily included bone marrow suppression, fatigue, and gastrointestinal reactions, indicating overall manageable toxicity. Conclusion As a subgroup analysis of the CAP study, this research suggests that radiotherapy combined with liposomal irinotecan, camrelizumab, and anti-angiogenic therapy demonstrates certain efficacy in advanced bone and soft tissue sarcomas that have failed multiple lines of treatment, with overall manageable adverse reactions. Future studies should expand the sample size.

ObjectiveTo find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas, so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas. MethodsFrom July 6th to October 26th 2023, one mosquito ovitrap was set up in each of the 4 orientations of east, south, west and north around the buildings in a multi-storey residential area in Jinhui Town, Fengxian District, Shanghai. Data was collected and recorded 72 hours after placement. The chi-square test was used to compare the mosquito ovitrap indices (MOIs) of two independent samples, and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples. ResultsAfter 16 weeks of surveillance, 997 mosquito ovitraps were recovered, of which 211 were positive, with the mosquito ovitrap index (MOI) of 21.16% and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap^-1. The MOIs were higher in September (24.22%) and October (23.96%), and the MOIs in the west, south and north within the two months were all above 20.00%. From July to October, the MOIs in the east, west, south and north were 20.70%, 22.20%, 25.50% and 16.20%, respectively, and the difference in MOIs among the 4 orientations was not statistically significant (χ²=6.647, P=0.084). Stratified analysis by month showed that in August, the south side of the multi-storey residential areas had the highest MOI (31.30%), the north side had the lowest MOI (1.30%), and there was a statistically significant difference in MOI in the east, west, south and north (χ²=25.986, P<0.001). In October, the MOI in the west was the highest (33.30%) and the MOI in the east was the lowest (6.30%), the difference in MOIs of the 4 orientations was statistically significant (χ²=12.007, P=0.007). The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower (19.20%) than that in the south side of the inner building (31.70%), and the difference in MOI was statistically significant (χ²=5.118, P=0.024). ConclusionThe study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work, and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes. Further indicators such as temperature, humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.

Objective In order to provide a better reference and basis for the selection of reasonable hypoglycemic drugs for clinical treatment,the study conducted a comprehensive clinical evaluation of the innovator sodium-glucose transporters 2(SGLT-2)inhibitors,based on A Quick Guideline for Drug Evaluation and Selection in Chinese Medical Institutions(the Second Edition).Methods The real-world studies,randomized controlled trials,Meta-analysis/systematic review,drug clinical use guidelines,expert consensus and drug description evaluation evidence were collected,and the included drugs were assigned and evaluated from five dimensions:pharmaceutical characteristics,efficacy,safety,economy and other attributes.Results All SGLT-2 inhibitors had evaluation scores above 75,with dagaglifloztin tablets having the highest score of 84.6,and canaglifloztin having the lowest score of 75.1.Conclusions All five original SGLT-2 inhibitors showed good clinical utility,the difference is that the participating original drugs have different advantageous intervals in clinical use.The results show that dagliflozin has the most ideal clinical utility,and its clinical use should be safer and more effective.Due to the short time on the market and insufficient evidence-based reasons,the advantages of clinical use of proline hemegliflozin are not obvious compared with other evaluated drugs.

Objective To explore the characteristics and influencing factors of drug-induced liver injury(DILI)associated with the postoperative use of propacetamol,and to provide guidance for rational clinical medication.Methods A retrospective analysis was conducted on hospitalized patients who underwent surgical treatment and were administered propacetamol from January 2022 to June 2024.Cases were screened based on established inclusion and exclusion criteria.Statistical analyses were performed on patients'demographic data,medication information,liver function indicators before and after medication,comorbid conditions,and concomitant medications to assess the incidence and influencing factors of propacetamol-related DILI.A multivariate Logistic regression analysis was conducted to identify related risk factors.Results A total of 7,579 patients were sampled,of which 2,114 met the inclusion criteria.Among them,531 patients(25.1%)experienced DILI,primarily presenting with abnormal liver function indicators.This included elevated alanine aminotransferase in 379 cases(71.4%),elevated aspartate aminotransferase in 197 cases(37.1%),elevated alkaline phosphatase in 209 cases(39.4%),and elevated total bilirubin in 92 cases(17.3%).Univariate analysis revealed that there were significant differences in gender,height,age,weight,body mass index(BMI),duration of propacetamol use,total medication dosage,concomitant use of hepatic-metabolized antibiotics,and history of liver disease between the DILI group and non-DILI group(P<0.05).Multivariate Logistic regression analysis showed that patient gender,BMI,total propacetamol dosage,liver-related diseases,and concomitant use of hepatic-metabolized antibiotics as independent risk factors for DILI(P<0.05).Conclusion The use of propacetamol for postoperative analgesia presents a risk for liver injury,and the risk is particularly pronounced in males,obesity,high-dose dosing,patients with underlying hepatic disease,and comorbid hepatic metabolism of antimicrobial drug use.It is recommended to strengthen the monitoring of liver function in clinical application,strictly control the dosage and duration of treatment,and avoid co-administration with hepatotoxic drugs to ensure the safety of drug use.

Objective:Analyze the risk factors for acute lung injury of postoperative acute lung injury(ALI)in patients with Stanford type A aortic dissection(STAAD),and construct a nomogram predictive model.Methods:A retrospective cohort study design was adopted.A total of 112 patients with STAAD who underwent surgical treatment in our hopital from January 2021 to August 2024 were included.They were divided into two groups according to the occurrence of ALI after the surgical:non-ALI group(73 cases)and ALI group(39 cases).Clinical data were collected from both groups of patients.The influencing factors of postoperative ALI in patients with STAAD were analyzed by multivariate logistic regression.Established nomogram prediction model based on influencing factors and validated.Results:Among 112 patients with STAAD who underwent surgical treatment,39 case postoperative ALI occurred,with an incidence rate of 34.82％.Age,preoperative creatinine,body mass index(BMI),preoperative white blood cell count,preoperative lactate and other aspects compared,The difference were statistically significant(P＜0.05).The length of stay in the intensive care unit(ICU)of the ALI group was longer than that of the non ALI group(P＜0.05).The intraoperative red blood cell transfusion volume and extracorporeal circulation time in the ALI group were higher than those in the non ALI group(P＜0.05).Long intraoperative cardiopulmonary bypass time,high BMI,high intraoperative red blood cell transfusion volume and high preoperative white blood cell count were risk factors for postoperative ALI(P＜0.05).The receiver operating characteristic(ROC)curve analysis results show that,the Area under the curve(AUC)of the nomogram prediction model was 0.871.When the optimal critical value was 0.472,its sensitivity and specificity wew 0.887 and 0.776,respectively.The internal validation results of Bootstrap show that,the C-index of the column chart prediction model was 0.862,with an absolute error of 0.032.The calibration curve is close to the ideal curve and the original curve,with a slope close to 1.Conclusions:Long intraoperative cardiopulmonary bypass time,high BMI,high intraoperative red blood cell transfusion volume and high preoperative white blood cell count are independent risk factors for postoperative ALI in patients with STAAD.The nomogram model constructed based on the above risk factors can effectively evaluate the risk of postoperative ALI in patients with STAAD.

Objective To explore the characteristics and molecular mechanisms of dynamic changes in ovarian function during natural aging in mice.Methods Eighteen female ICR mice of 2,6,10 and 14 months of age(referred to as 2 M,6 M,10 M,and 14 M)were included.The estrous cycle,ovarian index,pregnancy rate and embryo number were detected.The number of follicles was observed using HE staining.Serum anti-Müllerian hormone(AMH)levels were measured using ELISA.Protein and mRNA expression of P16,P21,proliferator-activated receptor-γ coactivator-1α(PGC-1α),and mitochondrial transcription factor A(TFAM)were detected through IHC and qPCR,respectively,and the protein expression of PGC-1α and TFAM was detected by Western blot.Relationships between indicators were evaluated based on Spearman's rank correlation coefficients and logistic regression analyses.Results Compared with estimates in the 2 M group,the percentage of estrous cycle disorders(P＜0.05 in 10 M group,P＜0.01 in 14 M group),ovarian index(P＜0.05 in 10 M group,P＜0.01 in 14 M group),serum AMH level(P＜0.01 in 10 M group,P＜0.01 in 14 M group),number of embryos(P＜0.01 in the 10 M group,P＜0.01 in 14 M group),and pregnancy rate(P＜0.01 in 14 M group)were significantly lower;the number of follicles at all levels and total number of follicles were lower(all P＜0.01),and the number of atretic follicles(all P＜0.01)was higher.Furthermore,P16 and P21 mRNA(P16:P＜0.01 in 10 M and 14 M groups;P21:P＜0.05 in 10 M group,P＜0.01 in 14 M group)and protein levels(P16:P＜0.01 in each group;P21:P＜0.01 in 10 M and 14 M groups)were elevated.Spearman's correlation analyses showed that the age in months was negatively correlated with the ovarian index,serum AMH level,primordial follicle number,number of embryos,and expression of PGC-1αand TFAM and positively correlated with the expression of atretic follicle,P16 and P21(all P＜0.01).Logistic regression analysis revealed a significant negative correlation between the age in months and pregnancy rate(P＜0.01).PGC-1α mRNA was significantly decreased(all P＜0.01),and TFAM mRNA was significantly decreased in 10 M and 14 M groups(P＜0.01).PGC-1α levels were significantly decreased in the 10 M group(IHC:P＜0.05;Western blot:P＜0.01)and 14 M group(all P＜0.01);TFAM levels were significantly lower in 6 M,10 M,and 14 M groups than in the 2 M group(IHC:P＜0.01;Western blot:P＜0.01).Compared with the 2 M group,expression levels of PGC-1α and TFAM were positively correlated with the ovarian index and serum AMH level and negatively correlated with P16 and P21 expression(all P＜0.01).Conclusions Ovarian function in mice declines progressively with age in months,as reflected by reductions in follicles and fertility and the up-regulation of aging markers,which may be associated with the decreased expression of the mitochondrial biogenesis factors PGC-1α and TFAM.
