ABSTRACT:Objective To observe the influence of saikosaponin-d (SSd)on the proliferation and the function of autophagy of human hepatocellular carcinoma (HCC)cell line SMMC-7721 to explore the possible mechanisms. Methods SMMC-7721 was cultured invitro and then treated with SSd of various concentrations (5.0,7.5,10.0, 12.5,15.0 and 17.5 mg/L)for 24,48 and 72 h.We used MTT to detect cell proliferation,selected the optimal concentration and time,and detected the expressions of BECN1 at mRNA and protein levels by PCR and Western blot.Results The inhibition rate of the proliferation of SMMC-7721 cell line increased with the increase of the concentration of SSd,and the highest inhibition rate (60%)appeared when the concentration reached 12.5 mg/L. The expression of BECN1 in the group with SSd was obviously higher than that in the control group (P<0.05). 3-MA decreased not only the expressions of BECN1 at mRNA and protein levels but also the expression of BECN1 when used in conjunction with SSd.Conclusion The inhibiting function of SSd on SMMC-7721 presents a dependency between drug concentration and function time,basically in line with the drug dose-effect relationship. SSd induces the occurrence of autophagic cell death through up-regulating the expression of BECN1 ,thus inhibiting the proliferation of SMMC-7 7 2 1 .

OBJECTIVETo investigate the clinical characteristics of a Chinese pedigree with cardiac conductive disease complicated by atrial fibrillation and the therapeutic effect of the treatments.

METHODSAll the family members including the proband were screened with routine examination, electrocardiography, echocardiograpy, Holter recording, chest X-ray, blood biochemistry tests and autoantibody test. The proband received dual chamber pacemaker implantation combined with oral amiodarone treatment for 3 months. The patient was monitored for thyreoid function and chest X-ray during the treatments, and was followed up for another 3 months.

RESULTSClinical evidence of organic heart disease was found in none of the family members. The proband showed recurrent dizziness and chest distress, which exacerbated after exercise, and ECG showed atrial fibrillation and severe A-V block. The proband's uncle was found to have atrial fibrillation and III degree A-V block after a syncope episode at the age of 30, and received a pacemaker treatment. Her grandpa died from a heart attack without detailed clinical documentations. No other family members showed abnormal ECG or a history of any heart events. The proband's condition was improved by treatments, after which ECG and Holter recording showed pace rhythm without atrial fibrillation.

CONCLUSIONCardiac conductive disease with atrial fibrillation can present in one family, and can be managed effectively and safely with implantation of dual chamber pacemaker combined with oral amiodarone.

Objective:To explore the efficacy and safety of mechanical thrombectomy (MT) in patients with minor stroke with large vessel occlusion (LVO).Methods:Twenty-three patients with minor stroke with LVO, admitted to our hospital from January 2017 to July 2019, were consecutively collected in our study; patients with contraindications of intravenous thrombolysis should be treated with direct thrombectomy, and the left were given bridging therapy (intravenous thrombolysis combined with MT). NIHSS scores were used to assess the degrees of neurological impairment at admission, and 12 h and 7 d after treatment. Vascular recanalization was assessed by modified cerebral infarction thrombolysis (mTICI) grading, with grading 2B-3 defined as successful recanalization. The prognoses 90 d after treatment were assessed by modified Rankin scale (mRS), and mRS scores≤2 was classified as having good prognosis. Safety indicators included symptomatic intracranial hemorrhage, incidence of complications, and mortality 90 d after treatment.Results:Twenty-two patients had successfully recanalization; 19 patients had mTICI grading 3 and 3 patients had grading 2B. The NIHSS scores were 3 (2, 5) at admission, 2 (2, 3) 12 h after treatment, and 2 (1, 2) 7 d after treatment, with significant difference ( χ2=14.028, P=0.001); NIHSS scores 12 h and 7 d after treatment were significantly lower than those at admission ( P<0.05). Sixteen patients (69.6%) enjoyed good prognosis and 7 patients (30.4%) had poor prognosis. In terms of safety, two patients had symptomatic intracranial hemorrhage,10 had systemic complications, and one died during 90-d of follow-up. Conclusion:MT is effective and safe in minor stroke patients with LVO.

Objective:To explore the efficacy of bridging therapy (BT) and direct endovascular therapy (DEVT) in patients with acute ischemic stroke induced by large vessel occlusion (LVO-AIS) within 4.5 h of onset.Methods:The clinical data of 154 patients with LVO-AIS within 4.5 h of onset, admitted to our hospital from January 2017 to July 2019, were retrospectively collected. Among them, 88 patients were hospitalized within 3 h of onset (54 accepted BT and 34 accepted DEVT); 66 patients were hospitalized within 3-4.5 h of onset (39 accepted BT and 27 accepted DEVT). The differences in clinical data and treatment efficacy between patients from the BT group and DEVT group that were hospitalized within 3 h of onset and within 3-4.5 h of onset, respectively, were compared. Multivariate Logistic regression was used to analyze the independent protective factors for favorable outcome 90 d after treatment in patients within 3.0-4.5 h of onset and within 3 h of onset, respectively.Results:(1) In patients within 3 h of onset: as compared with the DEVT group, the BT group had significantly higher improvement rate of neurological function at 24 h after treatment (41.2% vs. 70.4%) and higher percentage of patients enjoying favorable outcome 90 d after treatment (44.1% vs. 66.7%, P<0.05); multivariate Logistic regression analysis showed that BT was an independent protective factor for favorable outcome 90 d after treatment in patients within 3 h of onset ( OR=4.644, 95%CI: 1.238-12.805, P=0.041). (2) In patients within 3-4.5 h of onset: as compared with the BT group, the DEVT group had significantly higher proportion of patients having time from onset to groin puncture≤4 h, and significantly higher proportion of patients with favorable outcome 90 d after treatment ( P<0.05); multivariate Logistic regression analysis showed that the time from onset to groin puncture≤4 h was an independent protective factor for favorable outcome 90 d after treatment in patients within 3-4.5 h of onset ( OR=5.724, 95%CI: 1.192-11.676, P=0.024). Conclusion:For LVO-AIS patients, BT is the first choice in patients hospitalized in the early time window; and BT should be performed within 4 h of onset to the greatest extent for patients hospitalized in the late time window; if time from onset to groin puncture is not within 4 h, DEVT should be the first choice.

Objective: To study the prevalence and correlates of diabetes among HIV/AIDS who were on antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefectures (Dehong), Yunnan province. Methods: The database of HIV/AIDS receiving ART in Dehong was downloaded by using the basic information system of AIDS prevention and control in China. In this cross-sectional study, HIV/AIDS patients who were currently on ART and aged 18 years or above, were consecutively recruited, between July 2017 and June 2018, in Dehong. All the subjects underwent hemoglobin A1c (HbA1c) testing. Patient with diabetes was defined as meeting any of these indicators (HbA1c ≥6.5%, baseline FPG ≥7.0 mmol/L, FPG ≥7.0 mmol/L in the most recent visit). Both univariate and multivariate logistic regression analysis were carried on to evaluate the correlates of diabetes among the HIV/AIDS patients. Results: In total of 4 376 HIV/AIDS patients were included for analysis, with the average age as (43.7±10.1) years, proportion of males as 53.8% (2 356/4 376) and the HCV positive rate as 24.1% (1 055/4 376). The mean years was (8.9±3.8) years after the HIV diagnosis was made, and the mean duration on treatment was (6.8±2.9) years. The prevalence of diabetes was 11.4% (500/4 376). Through multivariate logistic regression analysis, data showed that the risk factors of diabetes of HIV/AIDS on ART were: aged 40 years or above, being male, HCV positive, baseline body mass index ≥24.0 kg/m², elevated TG ≥1.70 mmol/L in the most recent visit and baseline antiretroviral regimens under Efavirenz (EFV). Conclusions Prevalence rate of diabetes appeared higher in HIV/AIDS patients who were on ART in Dehong. Prevention and control measures should be targeted on HIV/AIDS patients who were with risk factors of diabetes as being elderly, male, HCV positive, overweight and higher TG. Further esearch is needed to evaluate the association between the use of EFV and diabetes.
