This article is to evaluate the clinical outcomes and health economics of minimally invasive surgery for hypertensive intracerebral hemorrhage(HICH).This review systematically compares clinical efficacy and economic value of three minimally invasive techniques:small bone window microsurgery,neuroendoscopic surgery and stereotactic drainage based on 12 randomized controlled trials(RCTs),7 cohort studies,and 8 economic evaluations 2019-2024.Cost-effectiveness analysis(CEA)and cost-utility analysis(CUA)were employed to assess resource utilization and health outcomes.Minimally invasive approaches overall outperform conventional craniotomy.Stereotactic surgery achieves the shortest hospitalization(5-8 days)and lowest direct costs;neuroendoscopy significantly improves quality of life(quality-adjusted life years(QALYs);and small bone window surgery offers the best postoperative stability.It is recommended to choose the surgical method based on patient characteristics and to optimize healthcare resource allocation through medical insurance payment reform and technology promotion.

Purpose To investigate the clinicopathological features and prognostic factors of follicular dendritic cell carcinoma(FDCS).Methods Hospital records of 23 patients diagnosed with FDCS were retrospectively re-viewed.The morphological,immunohistochemical features,including the detection of CD21,CD23,and CD35 using the EnVision method,and in-situ hybridization for Epstein-Barr virus encoded nuclear RNA(EBER)were evaluated.Clinicopathological characteristics were analyzed for the evaluation of prognosis.Results The median age of all 23 pa-tients was 50 years(range:27 to 72)and the female to male ratio was 1.3.The median maximum diameter of tumor was 7.0 cm(range:0.5 to 20.0 cm).One case was located in cervical lymph node,while another 22 were discovered in extranodal sites.20 cases were single organ and 3 cases were multiple organs involvement.Microscopically,tumor cells exhibited spindle,oval,or markedly pleomorphic morphology,accompanied by variable lymphoplasmacytic infil-tration in the stroma.CD21,CD35 and CD23 were positive in 22 of 23(95.6％),23 of 23(100.0％)and 4 of 15(26.7％)patients,respectively.EBER in-situ hybridization was positive in 9 of 23 patients(39.1％).The median follow-up time was 84.0(95％CI:50.7-117.3)months,and the 5-year survival rate was 80.2％(95％CI:62.8-97.6).Twelve(52.2％)patients were alive,5(21.7％)were dead,and 6(26.1％)were lost of follow-up.We es-tablished a pathological scoring system containing 5 indexes,i.e.,tumor maximum diameter,mitotic figures,tumor necrosis,cellular pleomorphism and histologic types.Patients with greater than 4 points had a significant poor progno-sis.Conclusion FDCS features a broad spectrum of histologic appearances and behavior.Combined morphological observations(HE staining),applications of a panel of follicular dendritic cell markers and EBER in-situ hybridization are helpful for accurate diagnosis.FDCS poses risks for recurrence,metastasis and death,and those with greater than 4 points in the scoring system have a significant poor prognosis.Long-term follow up is needed.

Objective To explore the value of low contrast dose and low flow rate one-stop craniocervical CT angiography(CT A)-cerebral CT perfusion(CTP)for detecting carotid atherosclerosis(CAS).Methods Totally 117 CAS patients were prospectively enrolled and divided into group A(n=19),B(n=52),C(n=46),and low contrast dose and low flow rate one-stop craniocervical CTA-brain CTP scanning,low contrast dose and low flow rate craniocervical CT A scanning,as well as conventional craniocervical CT A scanning were performed,respectively.Virtual monoenergetic images(VMI)of 40,50 and 60 keV were reconstructed in group A and B.The subjective and objective evaluations of image quality were compared among 3 groups.Results Subjective scores of image quality and diagnostic confidence of 40 and 50 keV VMI,and the diagnostic confidence of 60 keV VMI in group A and B were not significant different compared with those in group C(all P＞0.05).Signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of each segment of craniocervical blood vessels at 40 and 50 keV VMI in group A and B were all higher than those in group C(all P＜0.05).CNR of cavernous sinus segment of internal carotid artery(C5 segment),horizontal segment of middle cerebral artery(MCA)(A1 segment),lateral sulcus segment of MCA(M2 segment)and basilar artery(BA)segment in group A at 60 keV VMI were all higher than those in group C(all P＜0.05).SNR of C5 segment,A1 segment and BA segment,as well as CNR of BA segment of 60 keV VMI in group B were all higher than those in group C(all P＜0.05).Conclusion Low contrast dose and low flow rate one-stop craniocervical was feasible for detecting CAS.

Objective:To investigate the drug resistance of newly diagnosed HIV-1 infected patients in Shanghai and to provide reference value for clinical antiretroviral therapy (ART).Methods:The peripheral venous blood plasma of 196 newly diagnosed HIV-1 infected patients screened according to the inclusion and exclusion criteria at the Shanghai Public Health Clinical Center from April to June 2023 was collected, HIV-1 RNA was extracted, the pol region was amplified by reverse transcription-polymerase chain reaction (RT-PCR) for sequencing, the mutation sites and ART drug resistance were analyzed.Results:The plasma of 196 newly diagnosed HIV-1 infected patients was amplified successfully in 162 cases (amplification success rate was 82.65%). The subtypes consisted of CRF07_BC(51.23%), CRF01_AE (27.78%), and others (6.79%), CRF55_01B (5.56%), B (3.70%), CRF01_AE/B (3.70%) and CRF08_BC (1.23%). The overall transmitted drug resistance rate was 7.41%, the protease inhibitors (PIs), non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTIs), nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), integrase inhibitors (INSTIs) resistance rates were 3.09%, 3.70%, 0.00% and 0.62%, respectively. The proportion of NNRTIs-related mutation sites in B (66.67%) and CRF55_01B (88.89%) was higher than that in CRF07_BC (13.25%); the proportion of NNRTIs-related mutation sites in CRF55_01B (88.89%) was higher than that in CRF01_AE (22.22%) and other subtypes (18.18%), the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis showed that the probability of PIs-related mutation sites in CRF01_AE/B was 21.71 times that of CRF07_BC[odds ratio ( OR)=21.71, 95% confidence interval ( CI): 3.36-140.27, P=0.001]. Conclusions:The transmitted drug resistance among newly diagnosed HIV-1 infected patients in Shanghai is at the moderate epidemic level, mainly NNRTIs and PIs-related drug resistance, and the INSTIs resistance rate is low, the use of INSTIs in ART regimens should be considered.

Objective:To investigate the clinical characteristics, treatment and prognosis of juvenile dermatomyositis (JDM) complicated by sever gastrointestinal hemorrhage in children.Methods:A retrospective analysis was conducted on 4 JDM patients with sever gastrointestinal hemorrhage admitted to our hospital, from January 2017 to January 2025. Data including demographics, clinical manifestations, laboratory and imaging findings, treatment courses, and outcomes were reviewed.Results:The cohort comprised 4 patients (2 males, 2 females), with onset ages of 6.1, 6.2, 10.0 and 8.0 years. All presented with rash and fatigue and were diagnosed with severe refractory JDM (strongly positive anti-NXP2 antibodies). Sever gastrointestinal hemorrhage occurred 18, 12, 51, and 2 months after JDM diagnosis. Two cases had confirmed gastrointestinal infections due to contaminated food. Abdominal pain was the initial gastrointestinal symptom and black stool was observed in all cases, hemoglobin levels dropped below 60 g/L (case 1-4 decreased to 38, 59, 60 and 43 g/L respectively). All patients exhibited intestinal wall thickening. Active bleeding sites included the duodenum (3 cases: 2 cases near the duodenal papilla, 1 cases with diffuse duodenal oozing). Emergency endoscopic hemostasis was performed in 3 cases. One patient with diffuse duodenal bleeding required additional glucocortieoid pulse therapy after failed interventional embolization. Three patients stabilized following aggressive treatment of JDM, while 1 case died due to duodenal perforation.Conclusions:Anti-NXP2 antibody-positive JDM patients are prone to gastrointestinal involvement, particularly in chronic cases. Duodenal bleeding is common, with vascular erosion and deep mucosal ulcers posing life-threatening risks. For children with positive anti-NXP2 antibodies who present with abdominal pain and thickened intestinal walls, early endoscopic examination should be conducted as soon as possible to detect digestive tract lesions and provide timely treatment. Patients with severe digestive tract bleeding usually require active treatment for the underlying disease combined with endoscopic hemostasis therapy. Under timely treatment, the prognosis is relatively favorable.

Objective:To describe the application methods, types, and effects of wearable devices in sarcopenia.Methods:Following the guidelines for scoping reviews, a systematic search was conducted in PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, Wanfang Data, and VIP for literature related to wearable device applications in sarcopenia. The search period covered publications from database inception to August 1, 2024.Results:A total of 12 studies were included. Wearable devices in sarcopenia were primarily used for monitoring gait speed, surface electromyography, sleep duration, activity time, and supporting exercise interventions. Common types of wearable devices included activity trackers, smart belts, and smart wristbands. Their effectiveness, feasibility, and role in ensuring activity safety have been preliminarily demonstrated.Conclusions:The application of wearable devices in sarcopenia is still in its early stages but shows great potential. Currently, wearable devices are mainly used to monitor one or a few individual indicators. Future research should focus on developing multi-parameter monitoring devices and conducting large-scale, high-quality trials to validate their effectiveness in both monitoring and supporting exercise interventions. This will help promote their broader application and assist healthcare professionals in the early identification, diagnosis, prevention, and treatment of sarcopenia.
