Objective To analyze the associated factors on abnormal liver function(LF)in chronic schistosomiaisis japonica patients.MethodsThe clinical data of 120 inpationts with chronic schistosomiasis were collected and analyzed by logistic regression.The relevant treatment methods were summarized.ResultsThe associated factors on abnormal LF of the patients were hepatitis B,alcohol drinking,hyperlipidemia,nonalcoholic fatty liver disease(NAFLD),and obesity,respectively.The ordinary medication for improving liver function was effective to these causes.Praziquantal can be administrated successfully to these patients after LF normalized.ConclusionChronic schistosomiasis patients with abnormal LF but without severe vital organ diseases could be treated with praziquantal after their LF improving.

Objective:To explore the mediation effect of personality between negative life events and risky mentation of university students.Methods:A cross sectional investigation was conducted among 8 379 freshmen with the adolescent self-rating life events check list (ASLEC), the prodromal questionnaire(PQ-16) and the Eysenck personality questionnaire (EPQ). The data were analyzed by SPSS 23.0 and AMOS 24.0.Results:The total score of negative life events scale((31.16±0.58) vs (15.19±0.15)), the scores of neuroticism((58.20±0.36) vs (41.59±0.13)) and psychoticism((53.07±0.29) vs (47.71±0.08)) in the risk psychological state group were significantly higher ( t=26.611, 42.270, 17.286, all P<0.01), and the score of introversion-extroversion factor was significantly lower((49.83±0.42) vs (55.88±0.13), t=-13.634, P<0.01) than those in the risk-free psychological state group. There was a positive correlation between the scores of risk psychological state and negative life events( r=0.290, 0.334, both P<0.01), and the scores of risk psychological state and negative life events were positively correlated with the scores of personality neuroticism and psychoticism ( r=0.139-0.469, all P<0.01) in both risk psychological state and risk-free psychological state group.The risk psychological state score of college students was negatively correlated with the inside and outside personality score( r=-0.070, P<0.01), and the score of negative life events was not correlated with introversion-extroversion personality score in the risk psychological state group, while the score of risk psychological state, negative life events and introversion-extroversion personality score were negatively correlated in the risk-free psychological state group ( r=-0.177, -0.080, P<0.01). The personality of college students played a complete mediating role between negative life events and risk psychological state in the risk psychological state group, while the personality of college students in the risk-free psychological state group played a partial mediating role between negative life events and risk psychological state, accounted for 71.43% of the total effect. Conclusion:Negative life events not only directly lead to the risky mentation of college students, but also affect the risky mentation of college students by the mediation effect of introverted and extroverted tendency and unstable emotion.

The roles of Indian hedgehog (Ihh) signaling pathway in the proliferation and apoptosis of precartilaginous stem cells (PSCs) were investigated.PSCs,labeled with fibroblast growth factor receptor 3 (FGFR-3),were isolated from neonatal rats by immanomagnetic separation.After identifi-cation with FGFR-3 and Col Ⅱ,the cells were incubated with different concentrations of cyclopamine (cyclo),the specific inhibitor of lhh signaling pathway.The morphologic changes of the cells were observed under the inverted phase contrast microscope.The mRNA expression levels of Ibh,para-thyroid hormonerelated peptide (PTHrP),protein Patched (Ptch),Bcl-2 and p21 were detected by RT-PCR.The protein expression levels of Ihh and Ptch were measured by Western blot.MTT assay was used to examine the effects of cyclo on proliferation of PSCs.Apoptosis rate of PSCs was exam-ined by Annexin V/PI assay of flow cytometric analyses.After PSCs were incubated with cyclo,ob-vious morphologic changes were observed as compared with the control group.The mRNA expres-sion levels of PTHrP,Ptch and Bcl-2 were decreased to varying degrees in a cyclo dose-dependent manner.However,the expression levels of lhh and p21 mRNA were increased.The protein expres-sion of Ptch and Ihh had the same change as the mRNA expression.Meanwhile,cyclo could obvi-ously inhibit the proliferation and promote the apoptosis of PSCs.The results indicated that Ihh sig-naling pathway plays an important role in regulating the proliferation and apoptosis of PSCs,which is probably mediated by Bcl-2 and p21.

Objective:To analyze the safety and efficacy of endovascular treatment in fusiform aneurysms at V4 segment of vertebral artery.Methods:Twenty-five patients with fusiform aneurysms at V4 segment of vertebral artery, accepted endovascular treatment in Department of Cerebrovascular Diseases, Second Affiliated Hospital of Kunming Medical University from May 2016 to January 2022 were chosen; their clinical data were retrospectively analyzed. The short-term (within one month of surgery) and long-term (>8 months of surgery) complications were evaluated, including aneurysm re-bleeding and ischemic stroke. All patients were followed up for 3-21 months; aneurysm recurrence and parent arteries were evaluated by DSA. The prognosis of patients was evaluated by modified Rankin scale (mRS) at the last follow-up (mRS scores of 0-2 as good prognosis).Results:Twenty-six aneurysms involved in 25 patients, including 13 ruptured aneurysms and 13 un-ruptured aneurysms; 7 aneurysms were located at the dominant vertebral artery and 7 aneurysms involved in the origin of posterior inferior cerebellar artery (PICA). In these 13 ruptured aneurysms, 6 (46.15%) were treated with parent artery sacrifice and 7 (53.85%) were with stent-assisted coil embolization; in 13 un-ruptured aneurysms, 9 (69.23%) were treated with stent-assisted coil embolization and 4 (30.77%) were with flow diversion devices (Tubridge). Seven aneurysms (43.75%) used multi-stent in these 16 aneurysms accepted stent-assisted coil embolization. No short-term and long-term re-bleeding or ischemic stroke were noted in all patients. Twenty patients completed DSA follow-up, with a median follow-up time of 8 months; 3 patients had recurrent aneurysms and one had asymptomatic stent occlusion. All 25 patients completed the last follow-up (telephone or outpatient follow-up) in May 2022, and 24 had good prognosis.Conclusion:According to characteristics of dominant vertebral artery and relations between aneurysms and PICA, individualized endovascular treatment can be safe and effective in fusiform aneurysms at V4 segment of vertebral artery.
