Objective To compare the clinical efficacy of intraoperative intravenous tirofiban versus preoperative loading dose dual antiplatelet therapy in the acute phase LVIS stent-assisted coil embolization treatment for ruptured wide-necked intracranial aneurysms.Methods Patients with acutely ruptured,wide-neck intracranial aneurysms underwent LVIS stent-assisted coil embolization in the Department of Neurosurgery at Heze Municipal Hospital were retrospectively and consecutively enrolled from January 2017 to June 2023.According to the Chinese expert consensus on antiplatelet therapy for intracranial aneurysms,patients were divided into two groups based on the types of antiplatelet therapy they received:the loading-dose dual antiplatelet therapy(DAPT)group and the tirofiban group.Baseline and clinical data were collected and compared between the two groups,including age,sex,hypertension,diabetes mellitus,coronary artery disease,history of cerebral hemorrhage,preoperative Hunt-Hess grade,maximum aneurysm diameter,aneurysm neck width,and aneurysm location.Perioperative ischemic and hemorrhagic complications were collected and compared between the two groups.Perioperative ischemic complications included:intraoperative stent thrombosis(defined as filling defects in the parent artery,and,occlusion of the parent artery or stented branch during the procedure),and symptomatic ischemic infarction within 24 h postoperatively(confirmed by imaging with corresponding neurological deficits).Perioperative hemorrhagic complications included:intraoperative rupture of the target aneurysm(contrast extravasation or acute hemorrhage during embolization)and intracranial hemorrhage within 24 h postoperatively(new or worsened subarachnoid hemorrhage or intraparenchymal hemorrhage on CT).Clinical outcomes at 90 days were collected via telephone or outpatient follow-up,and evaluated using favorable prognosis defined as modified Rankin scale(mRS).A mRS score of 0-2 were defined as favorable prognosis and 3-6 as poor prognosis.Six-month postoperative imaging follow-up were collected,angiographic outcomes were categorized into four groups based on comparison with immediate post-embolization results:complete occlusion,total absence of contrast filling in the aneurysm sac;improved,reduced contrast filling;stable,unchanged contrast filling;and,recurrence,increased contrast filling.Results Totals of 108 patients with intracranial aneurysms treated by LVIS stent-assisted coiling were enrolled,with 30 males and 78females,aged32-75years(median age63[50,66]years).Among the108cases,55cases were assigned into the DAPT group,and 53 cases were included in the tirofiban group.(1)No statistically significant differences were observed between the tirofiban group and the DAPT group in baseline and clinical characteristics(all P＞0.05).(2)All patients underwent successful LVIS stent-assisted coiling,with a technical success rate of 100%.The total perioperative ischemic complications were 12.0%(13/108),including 4.6%(5/108)intraoperative stent thrombosis and 7.4%(8/108)symptomatic ischemic infarction within 24h after surgery.The total perioperative hemorrhagic complications rate was 1.9%(2/108),including 1 case of intraoperative aneurysm rupture and 1 case of postoperative intracranial hemorrhage within24h.92.6%(100/108)of the patients exhibited favorable prognosis and 7.4%(8/108)showed poor prognosis at the 90-day follow-ups.78.7%(85/108)of the patients accomplished at 6-month imaging follow-ups,the complete occlusion ratio was 94.1%(80/85)and the recurrence ratio was 2.4%(2/85).(3)The overall perioperative ischemic complication rates were 13.2%(7/53)in the tirofiban group and 10.9%(6/55)in the DAPT group,with no statistically significant difference(P=0.720).Intraoperative stent thrombosis occurred more frequently in the DAPT group(9.1%[5/55]vs.0,P=0.025),while symptomatic ischemic infarction within 24 h post-procedure was lower in the DAPT group(1.8%[1/55]vs.13.2%[7/53],P=0.028).The hemorrhagic complications occurred only in the DAPT group,with a rate of 3.6%(2/55),while no events observed in the tirofiban group.At the 90-day follow-up,the proportion of patients with favorable outcomes was 94.3%(50/53)in the tirofiban group and 90.9%(50/55)in the DAPT group,with no statistically significant difference between the groups(P=0.754).Conclusions Both intraoperative intravenous tirofiban and preoperative loading-dose DAPT demonstrated comparable safety profile and favorable clinical efficacy in the acute-phase treatment of ruptured wide-necked intracranial aneurysms with LVIS stent-assisted coil embolization.The results require further validation through large-scale prospective studies.

Bone repair remains an important target in tissue engineering, making the development of bioactive scaffolds for effective bone defect repair a critical objective. In this study, β-tricalcium phosphate (β-TCP) scaffolds incorporated with processed pyritum decoction (PPD) were fabricated using three-dimensional (3D) printing-assisted freeze-casting. The produced composite scaffolds were evaluated for their mechanical strength, physicochemical properties, biocompatibility, in vitro pro-angiogenic activity, and in vivo efficacy in repairing rabbit femoral defects. They not only demonstrated excellent physicochemical properties, enhanced mechanical strength, and good biosafety but also significantly promoted the proliferation, migration, and aggregation of pro-angiogenic human umbilical vein endothelial cells (HUVECs). In vivo studies revealed that all scaffold groups facilitated osteogenesis at the bone defect site, with the β-TCP scaffolds loaded with PPD markedly enhancing the expression of neurogenic locus Notch homolog protein 1 (Notch1), vascular endothelial growth factor (VEGF), bone morphogenetic protein-2 (BMP-2), and osteopontin (OPN). Overall, the scaffolds developed in this study exhibited strong angiogenic and osteogenic capabilities both in vitro and in vivo. The incorporation of PPD notably promoted the angiogenic-osteogenic coupling, thereby accelerating bone repair, which suggests that PPD is a promising material for bone repair and that the PPD/β-TCP scaffolds hold great potential as a bone graft alternative.

Objective To explore the efficacy of using a single branch stent-graft to treat primary intramural hematoma located at the distal arch or descending aorta in Stanford A type aortic intramural hematoma. Methods From July 2020 to November 2022, 10 patients with primary intramural hematoma of Stanford A type aortic intramural hematoma were treated with endovascular repair using a single branch stent-graft in the Department of Cardiovascular Surgery at The University of Hong Kong-Shenzhen Hospital. There were 9 males and 1 female, aged from 32 to 66 years, with a mean age of (47.0±10.4) years. All patients had intramural hematoma involving the ascending aorta and aortic arch, diagnosed as type A intramural hematoma, with the tear located in the descending aorta. Among them, 6 patients were complicated by ulceration of the descending aorta with intramural hematoma, and 4 patients had changes of the descending aortic dissection. All patients underwent endovascular stent repair, with 8 patients undergoing emergency surgery (≤14 days) and 2 patients undergoing subacute surgery (15 days to 3 months). Results There were no neurological complications, paraplegia, stent fracture or displacement, or limb or visceral ischemia during the perioperative period in all patients. One patient had continuous chest pain after surgery, and the stent had a new tear at the proximal end, requiring ascending aorta and partial arch replacement. As of the latest follow-up, all patients had obvious absorption or complete absorption of the intramural hematoma in the ascending aorta and aortic arch compared with before the operation. Conclusion Single branch stent-graft treatment of retrograde ascending aortic intramural hematoma is safe and effective, with good short-term results.

Objective　To analyze the epidemiological characteristics and infection pathways and virulence factors of one cholera outbreak in Fengxian District, Shanghai, China, in 2024, and to provide scientific basis for epidemic control and prevention. Methods　Epidemiologic data of cases of one cholera outbreak in Fengxian District in 2024 were collected using on-site epidemiologic survey methods; RT-PCR nucleic acid testing and bacterial culture were applied to carry out pathogenicity testing of cases, close contacts, environment, and food samples; and the genome sequences of the strains were obtained using second-generation gene sequencing. Results　The case was a 62-year-old woman, who presented to the doctor with diarrhea for 4 consecutive days, 4-5 times a day, with watery stools, which was not effectively relieved by self-administered medication. There was no history of traveling away from Shanghai for 5 days before the onset of the disease, and she was engaged in the preparation and delivery of food for rural banquets during the period. Vibrio cholerae O139 was detected in the anal swab sample of the case and the septic tank of the workplace on the 4th day after the onset of the disease; samples of turtle and links in the store selling turtle were cultured for Vibrio cholerae O139. The isolate carried several virulence-related genes such as ctxA, ctxB, HlyA, zot, rtxA, hapA, nanH, tdh, and T3SS. Comparison of the isolate with the O139 strain of cholera cluster within our country through the National Pathogenic Bacteria Recognition Network (NPBN) in recent years suggests that the closest environmental or aquatic animal isolate to the sequence of this strain is the turtle isolate uploaded at a place in Guangdong. Conclusion　This outbreak was a disseminated outbreak caused by the case's contact with turtle contaminated with Vibrio cholerae O139, and early detection of enteric infectious diseases such as cholera can be achieved by relying on the outpatient enteric cholera surveillance network.

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:To analyze the liver histological characteristics and clinically related factors in inactive hepatitis B surface antigen (HBsAg) carriers (IHC), and also explore whether antiviral treatment is necessary for IHC, as defined in the 2022 version of the hepatitis B prevention and treatment guidelines.Methods:A multicenter, retrospective cohort study was conducted. Two hundred and thirty-one IHC cases who underwent liver biopsy histopathological examination in nine medical institutions, including Beijing Youan Hospital affiliated with Capital Medical University, from January 2018 to December 2023 were included. General informative data, clinical serological markers, and transient elastography (TE) examination results were collected. Patients were divided into a positive (148 cases) and a negative group (83 cases) according to the results of hepatitis B virus (HBV) DNA detection. The differences in liver pathological inflammatory activity (G) and liver fibrosis stage (S) were analyzed between the two groups to explore the correlation between liver tissue conditions and clinically related factors. Comparsions of normally distributed continwous data, skeukd continuous data, and categorical data between groups are performed using t tests, Mann-Whitney U tests and χ2 tests, respectively. Results:The age of 231 IHC cases was 43 (38, 51) years old, with 95.2% (220/231) aged ≥30 years, and males accounted for 64.9% (150/231). HBsAg and HBV DNA levels were 131.9 (20.8, 400.9) IU/mL and 94.0 (0, 448.5) IU/mL, respectively, of which 35.9% (83/231) were HBV DNA negative (<20 IU/mL). The remarkable proportions of G≥2, S≥2, and liver injury (G≥2 and/or S≥2) in liver tissue were 16.5% (38/231), 29% (67/231), and 35.9% (83/231), respectively. The S≥2 proportion was significantly higher in the HBV DNA-negative group than the positive group (42.2% vs. 21.6%, P<0.001), and it mainly occurred in the population cohort over 30 years old (44.9% vs. 31.0%, P=0.04). The liver stiffness measurement (LSM), aspartate transaminase to platelet ratio index (APRI), and platelet (PLT) were significantly higher in the S≥2 group than the S<2 group ( P<0.05). Conclusion:Clinicians can comprehensively evaluate the degree of liver fibrosis in IHC based on clinical factors such as age, PLT, APRI, and LSM, even if the liver histological results are lacking. The China 2022 version guidelines define that nearly half of IHC has histological indications for antiviral therapy, and liver biopsy and prompt treatment can be recommended.
