Objective:To study the feasibility of domestic flow diverter(TFD) for the treatment of unruptured internal carotid artery small- and medium-sized wide-neck aneurysms.Methods:This is a retrospective case series study.The study retrospectively evaluated consecutive 54 patients with unruptured intracranial small- and medium-sized wide-neck aneurysms treated with TFD in the Department of Cerebrovascular Disease,the Second Affiliated Hospital of Kunming Medical University between October 2019 and January 2024. There were 11 males and 43 females, and the age of patients was (54.9±9.6) years (range:36 to 74 years). There were 63 aneurysms in 54 patients,6 of which were tandem multiple small aneurysms. One case had saccular aneurysms of bilateral internal carotid artery. The maximum diameter of aneurysm was (4.1±0.8) mm (range: 1.5 to 10.0 mm).The ratio of the maximum diameter of the aneurysm to the neck width diameter was 1.3±0.4 (range:0.4 to 2.4). The surgical and follow-up data were collected. The aneurysm embolization rate at the immediate operation and follow-up,and the complications were analyzed. The degree of aneurysm embolization was evaluated using the O′Kelly-Marotta (OKM) grading system,with OKM grade D as complete occlusion and grade C and above (C1,C2,C3 and D) as successful occlusion. Clinical outcomes of all patients were evaluated by modified Rankin scale(mRS).Results:For 63 aneurysms, 48 aneurysms were treated with TFD alone,and 15 aneurysms were treated with a combination of TFD and coiling. The immediate postoperative successful occlusion rate was 14.3% (9/63) and the complete occlusion rate was 3.2% (2/63). Follow-up results were obtained for all of the patients. The follow-up time ( M(IQR)) was 124 (182) days (range: 85 to 754 days). The time to aneurysm successful occlusion was 140.5 (151.5) days (range: 85 to 308 days). At final follow-up,the successful aneurysm occlusion rate was 68.3% (43/63) and the complete occlusion rate was 58.7% (37/63). The complete occlusion rate of the TFD group was 50.0% (24/48) and the TFD+coiling group was 13/15. All patients had no aneurysm rupture,ischemic complications and no recurrence of the aneurysm needed to retreatment during the intraoperative and follow-up period. A total of 3 mild haemorrhagic complications which were related to dual-antiplatelet agents. Twelve patients had asymptomatic mild-moderate stent stenosis. TFD covered 66 branch vessels totally. Only 6 branches were affected by the time of the last follow-up and none of the patients had relevant ischaemic symptoms. All of 54 patients were evaluated as mRS score<2 points at the last follow-up. Conclusion:Using TFD to treat internal carotid artery unruptured small and medium-sized wide-neck aneurysms can simplify the surgical procedure with low complication rate, which is a clinically optional treatment approach.

Herein,a new multifunctional hydrogel wound dressing was fabricated for the first time based on the crosslinking between catechol-modified chitosan(CHI-C)and bismuth sulfide-gold nanocluster nanoparticles(Bi2S3-Au NCs NPs)by simple stirring at room temperature within 1 min.Benefit from the good biocompatibility of CHI-C and excellent photothermal abilily of Bi2S3-Au NCs NPs,it could achieve postoperative photothermal therapy of tumor residual tissue and wound healing.More importantly,the as-prepared hydrogel with fluorescent property could accurately monitor the postoperative wound filling in real-time,which was critical to wound healing,especially for irregular wounds.The smart hydrogel was expected to provide a new perspective for preventing and reducing cancer recurrence and wound infection after surgery.

OBJECTIVE: To compare the effect of acupuncture based on syndrome differentiation and estazolam in the treatment of chronic insomnia and its influence on cognitive function. METHODS: A total of 90 patients with chronic insomnia were randomly divided into an acupuncture group and a medication group, 45 cases in each group. The acupuncture group was treated with acupuncture at Sishencong (EX-HN 1) and bilateral Shenmen (HT 7), Sanyinjiao (SP 6) combined with compatibility of acupoints based on syndrome differentiation, once a day for 6 d and then rest for 1 d, for a total of 4 weeks. The medication group was treated with oral estazolam tablets before bedtime, 1 tablet each time, for a total of 4 weeks. Before and after treatment, the scores of Pittsburgh sleep quality index (PSQI), mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) and auditory verbal memory test (AVMT) of the two groups were compared, and the effects were evaluated. RESULTS: After treatment, the PSQI sub-item scores and total scores of the two groups were lower than those before treatment ( P<0.05 ), and above scores in the acupuncture group were lower than those in the medication group ( P<0.05 ); the scores of MMSE, MoCA and AVMT in the two groups were higher than those before treatment ( P<0.05 ), and the scores in the acupuncture group were higher than those in the medication group ( P<0.05 ). The total effective rate of the acupuncture group was 80.0% (36/45), which was higher than 53.3% (24/45) in the medication group (P<0.05). CONCLUSION Syndrome differentiation acupuncture can improve the sleep quality and cognitive function of patients with chronic insomnia, and the curative effect is better than that of estazolam.

Objective To explore the potential biological functions and prognostic prediction values of non-apoptotic regulated cell death genes (NARCDs) in lung adenocarcinoma.Methods Transcriptome data of lung adenocarcinoma were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases. We identified differentially expressed NARCDs between lung adenocarcinoma tissues and normal tissues with R software. NARCDs signature was constructed with univariate Cox regression analysis and the least absolute shrinkage and selection operator Cox regression. The prognostic predictive capacity of NARCDs signature was assessed by Kaplan-Meier survival curve, receiver operating characteristic curve, and univariate and multivariate Cox regression analyses. Functional enrichment of NARCDs signature was analyzed with gene set variation analysis, Gene Ontology, and Kyoto Encyclopedia of Genes and Genomes. In addition, differences in tumor mutational burden, tumor microenvironment, tumor immune dysfunction and exclusion score, and chemotherapeutic drug sensitivity were analyzed between the high and low NARCDs score groups. Finally, a protein-protein interaction network of NARCDs and immune-related genes was constructed by STRING and Cytoscape software. Results We identified 34 differentially expressed NARCDs associated with the prognosis, of which 16 genes (ATIC, AURKA, CA9, ITGB4, DDIT4, CDK5R1, CAV1, RRM2, GAPDH, SRXN1, NLRC4, GLS2, ADRB2, CX3CL1, GDF15, and ADRA1A) were selected to construct a NARCDs signature. NARCDs signature was identified as an independent prognostic factor (P < 0.001). Functional analysis showed that there were significant differences in mismatch repair, p53 signaling pathway, and cell cycle between the high NARCDs score group and low NARCDs score group (all P < 0.05). The NARCDs low score group had lower tumor mutational burden, higher immune score, higher tumor immune dysfunction and exclusion score, and lower drug sensitivity (all P < 0.05). In addition, the 10 hub genes (CXCL5, TLR4, JUN, IL6, CCL2, CXCL2, ILA, IFNG, IL33, and GAPDH) in protein-protein interaction network of NARCDs and immune-related genes were all immune-related genes. Conclusion The NARCDs prognostic signature based on the above 16 genes is an independent prognostic factor, which can effectively predict the clinical prognosis of patients of lung adenocarcinoma and provide help for clinical treatment.

OBJECTIVE: To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies. METHODS: Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members. Then, peripheral blood samples of the proband and her family members were collected, and all exons of FGA, FGB and FGG and their flanks were amplified by PCR and sequenced to search for gene mutations. RESULTS: The proband had normal APTT and PT, slightly prolonged TT, reduced level of Fg activity (Clauss method). The Fg of the proband's aunt, son and daughter all decreased to varying degrees. The results of thromboelastogram indicated that Fg function of the proband and her family members (except her son) was basically normal. Gene analysis showed that there were 6233 G/A (p.AαArg35His) heterozygous mutations in exon 2 of FGA gene in the proband, her children and aunt. In addition, 2 polymorphic loci were found in the family, they were FGA gene g.9308A/G (p.AαThr331Ala) and FGB gene g.12628G/A (p.BβArg478Iys) polymorphism, respectively. The proband was injected with 10 units of cryoprecipitate 2 hours before delivery to prevent bleeding, and no obvious bleeding occurred during and after delivery. CONCLUSION Heterozygous mutation of 6233G/A (p.AαArg35His) of FGA gene is the biogenetic basis of the disease in this family with congenital dysfibrinogenemia.
