Objective·To investigate the clinical,pathological,and molecular genetic features and prognosis of epithelioid hemangioendothelioma(EHE)patients.Methods·Clinical and follow-up data of 12 EHE patients diagnosed at Renji Hospital,Shanghai Jiao Tong University School of Medicine from September 2016 to December 2023 were collected.Tissue samples were analyzed using hematoxylin-eosin(H-E)staining,immunohistochemistry(IHC),and fluorescence in situ hybridization(FISH).Results·Among the 12 patients,there were 3 males and 9 females,with a mean age of(47.17±11.15)years.Tumors were located in the liver(6 cases),lung(4 cases),mediastinum(1 case),and supraclavicular region(1 case).Nine patients were asymptomatic,while 3 presented with mild symptoms such as chest tightness and fatigue.CT imaging revealed that EHE patients with involvement of livers and lungs exhibited multiple nodules,and 2 cases had tumors in both organs.Patients with tumors in the supraclavicular region and mediastinum presented with solitary nodules.H-E staining demonstrated that tumor tissues were composed of epithelioid,dendritic,and intermediate cells,arranged in acinar,cord-like,or clustered patterns.Epithelioid cells had round vesicular nuclei and eosinophilic cytoplasm,with some showing a signet-ring appearance and cytoplasmic vacuoles.The stroma contained a mucoid matrix.IHC staining revealed that mesenchymal endothelial markers,including vimentin,CD31,ETS transcription factor ERG,and factor Ⅷ-related antigen,were positive in the tumor tissues,while epithelial markers showed low positivity with weak staining.The Ki-67 indexes were also low.FISH analysis showed that 10 patients had a calmodulin-binding transcription activator 1(CAMTA1)gene break,while 2 patients had a transcription factor E3(TFE3)gene break.Of the 12 patients,11 were followed up for 2 to 38 months,with a mean follow-up time of 21.7 months.Three patients achieved tumor-free survival,6 were alive with tumors,1 died 4 months after surgery,and 1 died of heart disease 24 months after surgery.Conclusion·EHE has atypical clinical features,a tendency to recur,a and variable prognosis.Accurate diagnosis requires a combination of histopathology,IHC,and a molecular testing.

Objective:To explore patterns of traditional Chinese medicine (TCM) use among patients with inflammatory bowel disease (IBD) in Jiangsu Province, China from 2019 to 2023.Methods:Using data from the IBD health data platform of the National Healthcare Big Data (Eastern) Center, a retrospective cohort study was conducted. We performed descriptive analyses on hospitalised patients diagnosed with IBD between 2019 and 2023, who received TCM treatment.Results:The study included 11 095 case records from 4 760 patients, with TCM diagnoses primarily indicating diarrhoea and abdominal pain. Ulcerative colitis (UC) accounted for 4 782 hospitalizations (3 103 patients), while Crohn's disease (CD) accounted for 6 313 hospitalizations (1 657 patients). Patient demographics showed a trend towards younger age and a higher proportion of males. Treatment utilisation was highest in southern Jiangsu compared with the central and northern regions. In terms of disease burden, all treatment costs showed a downward trend. In terms of external TCM therapies, UC patients tend to prefer plasters and enemas, while CD patients are more inclined to use acupuncture. Regarding herbal medicine, licorice, white atractylodes, and white peony root are commonly used single herbs for IBD patients.Conclusions:The number of IBD patients treated with TCM in Jiangsu Province has steadily increased from 2019 to 2023. It is important to identify effective TCM treatment methods to reduce the burden of patients.

Compared to conventional radiotherapy, FLASH-RT can deliver the total radiation dose to the target volume in an extremely short time, reducing the radiation-induced damage to normal tissue while maintaining similar anti-tumor effects. FLASH-RT has been in the clinical trial stage, with several clinical research result being reported. Based on the collected global clinical research result of FLASH-RT in recent years, this study systematically reviewed FLASH-RT′s safety, radiation-related side effects, treatment efficacy, opportunities, and challenges in clinical trials.

Objective:To explore the effect and safety of endoscopic tubular musculoskeletal tumor surgery (ETMS) technology in spinal tumors.Methods:Clinical data were retrospectively collected from 18 spinal tumor patients who were treated with ETMS technology at Tianjin Medical University Cancer Institute and Hospital ( n=16) or the Affiliated Hospital of Qingdao University ( n=2) from November 2022 to December 2023. The total cohort included 11 males and 7 females, with the age at 60.3±8.6 years (range of 41-76). Two cases were diagnosed with benign tumors, four patients were diagnosed with spinal hematologic malignancies while other 12 cases were patients with spinal metastases. After localization under the C-arm X-ray machine, the spinal endoscopic channel is established using dilators. Soft tissue is dissected under endoscopic guidance to create an artificial cavity. Subsequently, the saline medium relied upon by the spinal endoscopic technique is removed, and posterior decompression and tumor curettage are performed using tubular techniques. Frankel grade classification and paraplegia index were used to evaluate the improvement of postoperative function and the VAS score was performed in pain scoring. The surgical complications and tumor evaluation were observed by postoperative outpatient and telephone follow-up. Results:The ETMS technology was successfully completed in all 18 patients with the mean operation time of 240.3±80.2 min. The median of intraoperative bleeding was 200.0(172.5, 350.0) ml and the mean postoperative drainage was 131.4±69.5 ml. The median value of postoperative hospitalization days was 6.0(4.0, 10.25) d. The paraplegia index decreased from 1.5(0, 3.0) preoperatively to 0(0, 1.25) postoperatively ( Z=-2.599, P=0.009). All the patients presented an improvement in Frankel grading after surgery except for one patient (downgrading from grade E to grade D). There was significantly difference in Frankel grading between preoperative and postoperative groups ( Z=2.812, P=0.005). The median value of preoperative VAS score was up to 5.5(4.0, 7.0) while the median value at postoperative, one month after surgery and three months after surgery were 1.5(1.0, 2.25), 1.0(0, 1.0) and 0(0, 1.0), respectively (χ 2=44.641, P<0.001). The 3-month postoperative VAS improvement rate was 91.2% (range 75%-100%). During a mean follow-up period of 7.6±6.2 months, none of the 18 patients presented surgical complications or tumor recurrence at surgical region. Only one patient died at 3.2 months after surgery until the last follow-up due to respiratory failure after lung tumor progression. The mean survival of the total cohort was up to 13.3 [95% CI (11.5, 15.0)] months. The 16 cases with spinal metastases or spinal hematological malignancies had a mean survival of 13.2 [95% CI (11.3, 15.0)] months. Conclusion:The ETMS technology presented good efficacy and safety in treatment of spinal tumors with low blood supply and with diameter less than 5cm.

Objective To evaluate the economic value of using glucagon-like peptide-1 receptor agonist(GLP-1RA)in combination with metformin for the treatment of type 2 diabetes mellitus(T2DM).Methods Based on 7 randomized controlled clinical trials(RCTs),Markov model was built to simulate the dynamic changes of metformin alone or combined with GLP-1RA in the treatment of T2DM patients without or with complications and death from the perspective of China's health system.Quality-adjusted life years(QALYs)was used as a health output indicator and 3 times China's per capita gross domestic product(GDP)in 2023 was set as the willingness-to-pay(WTP)threshold.The cycle was at the rate of 1 year and a total of 20 years cohort simulation in Markov model was applied to obtain long-term cost and effect of each treatment strategy.The incremental cost-utility ratio(ICUR)was analyzed as the primary evaluation indicator and the sensitivity of cost,utility and discount was performed to test the stability of the results.Results Compared with metformin alone,the ICUR of GLP-1RA including liraglutide,dulaglutide,exenatide,loxenatide,semaglutide combined with metformin were all below the WTP threshold,and the increased cost was acceptable.Extending the simulation time to 30 years or 50 years had no effect on results.The results of probability sensitivity analysis showed that the cost effect of semaglutide 0.5 mg combined with metformin had the highest probability of a cost-utility advantage of 99.7％among all the treatment strategies when WTP threshold was 3 times China's per capita GDP in 2023(268 074 yuan).Conclusion GLP-1RA,including liraglutide,dulaglutide,exenatide,lixisenatide,and semaglutide,at the regular recommended dose combined with metformin,would present higher cost-utility compared to metformin monotherapy.

Objective To evaluate the efficacy and safety of glucagon-like peptide 1 receptor agonists(GLP-1RA)in type 2 diabetes mellitus(T2DM)patients with overweight or obese.Methods PubMed,Embase,Cochrane Library,Ovid,ClinicalTrial.gov,SinoMed,CNKI,WanFang Data and VIP databases were electronically searched to collect randomized controlled trials(RCTs)on the efficacy of GLP-1RA in the treatment of T2DM patients with overweight or obese from January 1,2005 to November 1,2023.Two researchers independently screened the literature,extracted data and evaluated the risk of bias of the included studies.R software was then used for meta-analysis.The level of evidence was assessed by using the GRADE system.Results A total of 71 RCTs were included,including 29 476 patients.The results of Meta-analysis showed that compared with other hypoglycemic drugs,GLP-1RA showed superior effects in improving HbAlc status(WMD=-0.55,95％CI-0.65 to-0.45,P＜0.001)and weight loss(WMD=-2.61,95％CI-3.25 to-1.97,P＜0.001),while the effect on fasting plasm glucose was time-dependent(within 16 weeks:WMD=0.25,95％CI-0.17 to 0.66,P=0.250;16 to 52 weeks:WMD=-0.06,95％CI-0.32 to 0.20,P=0.650;over 52 to 104 weeks:WMD=-1.67,95％CI-1.91 to-1.43,P＜0.001).In terms of safety,the incidence of GLP-1RA's adverse reactions was higher than other hypoglycemic drugs(RR=1.11,95％CI 1.07 to 1.15,P＜0.001);the incidence of hypoglycemia was lower with GLP-1RA than with insulin(RR=0.58,95％CI 0.48 to 0.71,P＜0.001)and similar to oral hypoglycemic drugs(RR=0.83,95％CI 0.58 to 1.19,P=0.310).According to the GRADE assessment,only the certainty of the evidence for the results of the incidence of hypoglycemia was moderate,and the certainty of the evidence for the other results was low.Conclusion Current evidence shows that for T2DM patients with overweight or obese,GLP-1RA especially semaglutide,was more effective in lowering blood glucose,controlling body weight and reducing the occurrence of hypoglycemia than placebo,insulin and oral hypoglycemic drugs.

Objective:To investigate factors influencing the timing of laparoscopic surgery in children with cryptorchidism.Methods:A retrospective analysis was conducted on data from 150 children with cryptorchidism treated at Linyi Central Hospital between January 2020 and June 2023. The children were grouped based on the median age of those who underwent surgery, with 75 children in the low age group and 75 children in the high age group. The timing of operation for included children was analyzed. Univariate and multivariate analyses were performed to assess laparoscopic operation timing in children with cryptorchidism. A predictive model for laparoscopic operation timing was constructed, and its prediction efficiency was analyzed.Results:Univariate analysis revealed significant differences in family income level, medical expense payment method, parents' education level, and residence attributes among children who underwent surgery at different timings ( χ2=12.37, 21.70, 9.28, 9.52, 7.73, all P < 0.05). Multivariate analysis demonstrated that independent risk factors for delayed laparoscopic surgery in children with cryptorchidism included low family income, self-payment of medical expenses, low parents' education level, and rural residence ( OR = 0.31, 0.21, 0.08, 0.05, 0.12, 0.13, 0.14, 0.21, 0.42, all P < 0.05). Based on the results of the multivariate analysis, a nomogram risk model was constructed with a C-index of 0.713. This model utilized independent influencing factors and the prediction probability of the P-value to predict the timing of operation. The Yoden index values were 22.67%, 22.67%, 25.33%, 28.00%, 22.67%, and 60.00%, respectively. Conclusion:Children with cryptorchidism still experience delayed surgery, which is attributed to several factors. The prediction model constructed using these influencing factors demonstrates good prediction efficiency.
