ObjectiveThis paper aims to investigate the protective effects of the Tanyu Tongzhi Youhua prescription（TYTZP） against myocardial ischemia/reperfusion injury in rats via regulation of the cyclic GMP-AMP synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway. MethodsFifty-six 8-week-old male Sprague-Dawley （SD） rats were randomly divided into sham group， model group， ticagrelor group （32.4 mg·kg^-1）， RU320521 （RU.521cGAS inhibitors） group （5 mL·kg^-1）， groups of TYTZP with low dose （3.6 g·kg^-1）， medium dose （7.2 g·kg^-1）， and high dose （14.4 g·kg^-1）， with eight rats per group. The ticagrelor group and groups of TYTZP with different doses received pre-treatment for seven days according to their respective protocols. The RU.521 group received an intraperitoneal injection one hour before modeling. A rat model of the no-reflow phenomenon in myocardial ischemia/reperfusion injury was established by ligating the left anterior descending coronary artery in situ. Myocardial no-reflow area was determined by thioflavin staining. Histopathological morphology of myocardial tissue was observed via hematoxylin and eosin （HE） staining. Cardiac function was detected by echocardiography. Myocardial microcirculation function change was observed by using real-time myocardial contrast echocardiography. The myocardial enzyme levels in the serum were measured by serum biochemical analysis. The double-stranded DNA （dsDNA） levels were detected by using PicoGreen. The protein expression of cGAS， STING， and nuclear factor-κB （NF-κB） p65 in myocardial tissue was detected by Western blot. The levels of cardiac troponin Ⅰ （cTNⅠ）， cardiac troponin T （cTNT）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the peripheral blood were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham group， the model group showed a significantly increased myocardial no-reflow area （P<0.01）. Myocardial fiber rupture and disarray and inflammatory cell infiltration were observed by HE staining. The ultrasound results indicated that left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） （P<0.01） were significantly decreased. Real-time myocardial contrast echocardiography showed that the peak time of myocardial blood perfusion was significantly prolonged （P<0.01）， and the levels of creatine kinase （CK）， creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， cTNⅠ， cTNT， and dsDNA were significantly elevated （P<0.01）. Western blot results showed that the myocardial protein expressions of cGAS， STING， and NF-κB p65 were upregulated （P<0.01）. ELISA results showed that the inflammatory factors in the serum such as IL-6， IL-1β， and TNF-α were increased （P<0.01）. Compared with the model group， the group of the TYTZP significantly reduced the levels of myocardial enzyme， troponins， and dsDNA （P<0.01， P<0.05）， improved cardiac function and myocardial microcirculation， alleviated histopathological morphology and inflammatory infiltration， inhibited activation of the cGAS/STING pathway， reduced the expression of NF-κB p65 （P<0.01， P<0.05）， and inhibited inflammatory response. ConclusionThe TYTZP mitigates the no-reflow phenomenon in myocardial ischemia/reperfusion injury， and its mechanism is associated with inhibiting the activation of the cGAS/STING pathway and attenuating inflammatory responses.

This study aims to analyze the screening results and epidemiological characteristics of prostate cancer (PCa) among elderly males in the rural areas of Songjiang, Shanghai City, through the implementation of a preliminary prostate-specific antigen (PSA) screening based on a community-linkage model, and to explore an effective screening approach. A retrospective observational study design was employed to collect data from residents who underwent PSA screening at Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine, in collaboration with multiple community health service centers in Songjiang District, Shanghai City, between June 2022 and June 2024, through free clinics and annual health examinations. Prostate biopsy was recommended for individuals with total PSA (tPSA) levels >10 ng/ml and those with 4 ng/ml≤tPSA≤10 ng/ml and abnormal free-to-total PSA (f/tPSA) ratios. Clinical characteristics of detected PCa patients were analyzed. Follow-up was conducted through phone calls and home visits by family doctors, coupled with enhanced health education. The results indicated that a total of 17 198 residents participated in the screening, among which 2 234 (12.99%) had tPSA levels between 4 ng/ml and 10 ng/ml, and 257 (1.49%) had tPSA levels >10 ng/ml. Ultimately, 417 residents underwent prostate biopsy, with 171 being diagnosed with PCa, yielding a positive biopsy rate of 41.00% and a PCa detection rate of 0.99%. The predominant pathological subtype among PCa patients was adenocarcinoma (168 cases, 98.24%). Of the 146 PCa patients who received treatment, the majority were classified as intermediate or high-risk (124 cases, 84.93%). Furthermore, with the optimization of the screening model, there was a significant increase in the proportion of subsequent outpatient visits. In conclusion, the community-linkage-based PSA screening model demonstrated high effectiveness in screening for PCa among elderly males in the rural areas of Songjiang, Shanghai City. Epidemiological findings revealed that PCa patients in this region are primarily composed of intermediate and high-risk groups, highlighting the need for intensified early screening and health education.

Purpose To investigate the relationships between the genetic variations and clinicopathological fea-tures of thyroid carcinoma in a single-center cohort.Methods The correlation between genetic profiling and clinico-pathologic characteristics of thyroid carcinomas detected by next-generation sequencing was analyzed.Results 93.7％of 238 cases of thyroid cancer had Class Ⅰ or Class Ⅱ variations.Compared with TCGA cohort,the single-center of pa-tients with papillary thyroid cancer(PTC)were younger(44.4±12.4 vs 46.8±15.5,P=0.043),and the rate of lymph node metastasis was higher(57.5％vs 49.2％,P=0.046).The frequency of BRAF gene mutation was signifi-cantly higher(82.4％vs 59.7％,P＜0.001),that of RAS gene mutation(2.3％vs 12.9％,P＜0.001)and TERT promoter mutation was lower(1.8％vs 9.4％,P＜0.001).There were no differences in the incidences of RET fusion(5.4％vs 6.8％,P=0.484)and NTRK fusion(4.1％vs 2.1％,P=0.127).Gene mutations were detected in 210 of 221(95.0％)patients with PTC,including BRAF(182/221,82.4％),RET fusion(12/221,5.4％),NTRK fusion(9/221,4.1％),FGFR amplification(6/221,2.7％),CCND1 amplification(6/221,2.7％),FGFR19 am-plification(6/221,2.7％),RAS(5/221,2.3％),PIK3CA(5/221,2.3％),and TERT(4/221,1.8％).NTRK fusion was associated with younger age(P=0.049)and higher T stage(P=0.005),while TERT promoter mutation was associated with older age(P=0.003)and higher T stage(P=0.001).8.6％(19/221)of thyroid papillary car-cinoma had at least two driver gene variants and tended to occur in patients with older age(P=0.001)and higher T tage(P=0.001).Higher mutation allele fraction(MAF)of BRAF was associated with T stage(P＜0.001)and N stage(P=0.017).Conclusion Chinese patients with papillary thyroid carcinomapatients show unique genetic vari-ant characteristics,and the patients with NTRK fusion,TERT promoter mutation,multiple driver gene variations,or high MAF of BRAF show specific clinicopathologic features.

Migraine disorders, a common disabling headache condition, is the second largest contributor to global neurological disability-adjusted life-years. Since 2000, migraine surgery has been pioneered and elaborated by plastic surgeons. For certain patients, migraine episodes are associated with "trigger sites" caused by compression of the peripheral nerves in the head and neck region. Botulinum toxin type A injections or nerve blocks, clinical manifestations and image studies can help confirm the trigger sites. Surgical deactivation of the trigger sites can effectively alleviate or eliminate migraine disorders, with the optimal result incorporated with experience and principles of plastic and cosmetic surgery.

Objective To investigate the application of intra pelvic pressure(IPP)in ultramicro-channel percutaneous nephrolithotripsy.Methods From January 2022 to January 2023,60 patients with urinary calculi who needed Super mini-PCNL(SMP)in The First Hospital of Jiaxing selected as the study objects.According to random number method,the patients were divided into control group and experimental group,with 30 cases.Both groups were treated with ultra-micro channel percutaneous nephrolithotripsia,while the experimental group was monitored and regulated IPP in real time during the operation,and observed and compared clinical indicators,IPP,fever,urinary protein,renal function,hemoglobin(Hb)and adverse reactions between the two groups.Results Compared with the control group,the hospitalization time of experimental group was shortened and the stone clearance rate was increased(P<0.05).The IPP levels of experimental groups at 6min,12min,24min and 36min were lower than those of control group(P<0.05).The fever of experimental group was lower than that of control group at 2d,3d,4d and 5d after operation(P<0.05).The urinary protein level of experimental group was lower than that of control group at 1d,2d,3d and 4d after operation(P<0.05).Compared with control group,blood urea nitrogen(BUN)and serum creatinine(SCr)levels of experimental group were decreased,and Hb levels were increased(P<0.05).The incidence of adverse reactions in experimental group was lower than that in control group(P<0.05).Conclusion Monitoring and adjusting intrapelvic pressure during super-mini percutaneous nephrolithotomy is beneficial in reducing postoperative fever in patients with urolithiasis,reducing urinary protein expression and kidney function damage,and controlling the occurrence of adverse reactions.It is worth recommending.

In magnetic resonance examination,the interaction between implants and the radio frequency(RF)fields induces heating in human tissue and may cause tissue damage.To assess the RF-induced heating of implants,three steps should be executed,including electromagnetic model construction,electromagnetic model validation,and virtual human body simulations.The crucial step of assessing RF-induced heating involves the construction of a test environment for electromagnetic model validation.In this study,a hardware environment,comprised of a RF generation system,electromagnetic field measurement system,and a robotic arm positioning system,was established.Furthermore,an automated control software environment was developed using a Python-based software development platform to enable the creation of a high-precision automated integrated test environment.The results indicate that the electric field generated in this test environment aligns well with the simulated electric field,making it suitable for assessing the RF-induced heating effects of implants.
