Forty-five male mice were used and divided into three groups: i.e. experimental gastric ulcer group, saline control group and normal control group. After experimental gastric ulcer was induced, the mice of three groups received intraperitoneal injection of colchicine and were sacrificed 3h later at 3, 6, 9 and 20 days, respectively. The antral mucosa was removed and processed by Sternberger's immunocytochemical PAP method to show G cells and counterstained with hematoxylin. In normal control group, the mitotic index of the antral mucosal epithelial and glandular cells was 5.93?1.23; the percentage of G cells was 2.76?0.45; the mitotic index I of G cells (the number of the mitotic G cells per 100 G cells) was 0.85?0.18; and the mitotic index II of G cells (the number of mitotic figures of the G cells per 100 antral epithelial, glandular and G cells) was 0.02?0.01. The mitotic index of the antral mucosal epithelial and glandular cells, the percentage and the mitotic index II of G cells on 6th, 9th and 20th days in experimental gastric ulcer group was raised and showed highly significant statistical difference from that of the control group, respectively. The mitotic index I of G cells was raised on 9th day in the experimental gastric ulcer group and significant difference between experimental gastric ulcer group and the control group was found. It also revealed a significant diference in the experimental gastric ulcer group as compared with saline control group on 20th day. The percentage of G cells on 6th day was most high, but the peak of mitotic number of G cells appeared on 9th day in the experimental gastric ulcer group. The distribution of G cells was found upward in the glands near the ulcer on 3rd and 6th day than in normal control. These findings suggest that the number, origin, distribution and shape of the G cells in the pyloric glands exhibited dynamic changes with the passage of time. The results suggested that the G cells might participate in the regulation of regeneration of antral mucosa during experimental gastric ulcer.

OBJECTIVETo observe the clinical effect of acupuncture for depression and to discuss its impact on the content of 5-HT in patients with depression.

METHODSEighty patients with depression were randomly divided into an acupuncture group and a western medication group,40 cases in each one. Acupuncture was applied in the acupuncture group,Siman(KI 14),Shenshu(BL 23),Guanyuan(CV 4),Dazhui(GV 14),Yinlingquan(SP 9), Zusanli(ST 36),Taichong(LR 3),Yanglingquan(GB 34) and Jingming(BL 1) were selected, the intensive moxibustion was applied at G(uanyuan(CV 4). Fluoxetine was treated with oral administration in the western medication group. The treatments of six weeks were required in each group. The Hamilton depression rating scale (HAMD) was applied to evaluate efficacy and serum 5-HT was detected before and after treatment in the two groups.

RESULTSAfter treatment,the scores of HAMD were decreased obviously in the two groups compared with those before treatment (scores in the acupuncture group: 24. 48 ± 0. 28 vs 8. 95 ± 2. 24; scores in the western medication group: 24. 14±0. 24 vs 10. 29±1. 30),and the differences were statistically significant (both P<0. 05). Between the two groups,the scores of HAMD in the acupuncture group at the end of the lst,2nd,4th,6th weeks were superior to those in the western medication group (all P<0. 05). The content of serum 5-HT after treatment was increased markedly compared with that before treatment [the content in the acupuncture group: (26. 21 2. 36)pg/mL vs (52. 07 ± 0. 56)pg/mL, the content in the western medication group:(26. 26±2. 31)pg/mL vs (51. 70±0. 52)pg/ mL, both P<0. 05]. But there was no statistic significance between the two groups(P >0.05).

CONCLUSIONThe efficacy of acupuncture for depression is superior to that of western medication with fluoxetine.

Objective The aim of the present study is to measure multi-directional strain in patients with hyperuricemia through 3-dimensional speckle-tracking echocardiography (3D-STE) in order to investigate the left ventricular function early changes and clinical application value of 3D-STE. Methods 3-dimension dynamic images of left ventricular full volume in Apical 4-chamber heart view was collected and stored. 3-dimensional specke-tracking technology was applied to measure and compare the left ventricular multi-directional strain of patients with hyperuricemia and healthy controls in order to evaluate the left ventricular systolic function. Results A total of 24 healthy controls and 38 patients with hyperuricemia were included into the study. Among them,patients with hyperuricemia were divided into simple hyperuricemia group(n=12), hyperuricemia complicated with hyperlipidemia group (n=16)and hyperuricemia complicated with both hyper-tension and hyperlipidemia group (n=10). The circumferential strain [(-18.8±4.4)% vs (-25.9±6.4)%, t=-3.48, P=0.001] and area strain [(-31.2±3.9)% vs (-36.8±7.1)%, t=-2.55, P=0.018] of patients with simple hyper-uricemia significantly decreased compared with healthy controls. Besides, the circumferential strain [(-19.9 ± 5.8)% vs (-25.9 ±6.4)%, t=-3.02, P=0.002], longitudinal strain [(-12.6 ±3.3)% vs (-14.4 ±2.5)%, t=-1.95, P=0.038] and area strain [(-29.9±6.6)% vs (-25.9±6.4)%, t=-3.15, P=0.001] of patients with hyperuricemia complicated with hyperlipidemia significantly decreased compared with healthy controls. Conclusion Myo-cardial strain of patients with hyperuricemia complicated with hyperlipidemia or not is both decreased, indicating a decline in left ventricular systolic function.

Objective:To investigate the status of cognitive function in patients with acute cerebral infarction after intravenous thrombolysis, and analyze its influencing factors.Methods:From August 2020 to December 2021, convenience sampling was used to select 100 patients with cognitive impairment after intravenous thrombolysis for acute cerebral infarction admitted to the Department of Neurology of Shaoxing People's Hospital as the research object. The patients were followed up three months after intravenous thrombolysis. The Montreal Cognitive Assessment (MoCA) Scale and Self-made Cognitive Motor Training Compliance Scale and Exercise Training Compliance Scale were used to evaluate the cognitive function recovery and training compliance of the patients. Univariate analysis of variance and Logistic regression were used to analyze the influencing factors of cognitive function in patients with acute cerebral infarction after intravenous thrombolysis. A total of 100 questionnaires were distributed, 100 valid questionnaires were recovered with the recovery rate of 100%.Results:Three months after intravenous thrombolysis in patients with acute cerebral infarction, there were 85 patients with good cognitive function and 15 patients with abnormal cognitive function. Multivariate Logistic regression analysis showed that combined with hypertension, combined with abnormal glucose and lipid metabolism, National Institutes of Health Stroke Scale scores, thrombolysis time, infarct site, compliance with cognitive training and motor training were risk factors for cognitive function of patients with acute cerebral infarction after intravenous thrombolysis ( P<0.05) . Conclusions:Cognitive function of patients with acute cerebral infarction after intravenous thrombolysis is related to hypertension, abnormal glucose and lipid metabolism, NIHSS score, thrombolysis time, infarct location, and compliance cognitive with training, motor training. Ultra-early intravenous thrombolysis can protect cognitive function in patients with acute cerebral infarction. It is recommended to strengthen the prevention and control of the above risk factors and carry out early cognitive training and motor training to promote the early recovery of patients.

Objective:To investigate the clinical features of drug-induced hypersensitivity syndrome (DiHS) and enhance the recognition of its diagnosis and treatment.Methods:Drug-induced hypersensitivity syndrome diagnosed in the Second Xiangya Hospital of Central South University in recent 6 years were retrospectively analyzed and summarized.Results:Of 35 cases of drug-induced hypersensitivity syndrome there were ten types of suspected drugs. Antibiotics were the most common allergy-inducing drug, followed by allopurinol, antiepileptics, and non-steroidal anti-inflammatory drugs. The expected clinical findings of DiHS were characterized by skin rash, fever, enlarged lymph nodes, which may be accompanied by eosinophilia, liver function damaged. The lesions of DiHS were variable and the majority of cases 65.71%(23/35) were characterized by eruptive papules.The main therapeutic approach of DiHS was systemic application of glucocorticoids and intravenous immunoglobulin (IVIG). When necessary its combination with immunosuppressant or hemoperfusion (HP).Conclusions:DiHS should be on the high alert when a patient with medication history, rash, high fever and lymph nodes large, accompanied by eosinophilia, liver function damaged. Predictors of good prognosis are early diagnosis and treatment.

Objective:To explore the clinical efficacy of ultrasound-indicated cervical cerclage in twin pregnancies.Methods:This retrospective cohort study included 96 asymptomatic twin pregnancies with cervix length (CL)≤2.5 cm at 16-27 +6 weeks indicated by transvaginal ultrasound from January 2013 to May 2022 in Fujian Maternity and Child Health Hospital. They received either cervical cerclage (cerclage group, n=45) or conservative treatment (conservative group, n=51). The subgroup analysis was further performed after stratifying the subjects into the CL≤1.0 cm subgroup, the CL>1.0-≤1.5 cm subgroup, and the CL>1.5 cm subgroup. Two independent samples t-test, Mann-Whitney U test, and Chi-square test were used to compare the differences in the pregnancy and perinatal outcomes between different groups. Multivariate logistic regression was used to analyze the impact of cervical cerclage on pregnancy outcomes of women with different CLs. Results:The average gestational age at delivery and the prolonged gestation were significantly greater in the cerclage group than those in the conservative group [35.9 (34.9-37.0) weeks vs 34.9 (29.1-36.1) weeks; 10.7 (9.6-13.1) weeks vs 8.7 (4.8-11.0) weeks, Z=－2.59 and -3.63, both P<0.05]. The incidences of preterm birth before 34 weeks and 28 weeks, chorioamnionitis, and preterm premature rupture of membrane were lower in the cerclage group than those in the conservative group [17.8% (8/45) vs 45.1% (23/51), χ2=8.16; 2.2% (1/45) vs 15.7% (8/51), Fisher' exact test; 8.9% (4/45) vs 25.5% (13/51), χ2=4.52; 15.6% (7/45) vs 33.3% (17/51), χ2=4.03; all P<0.05]. There were no statistically significant differences in the proportion of postpartum hemorrhage and live births between the two groups (both P>0.05). In the women with CL≤1.0 cm, the cerclage group had a greater gestational age at delivery [36.0 (34.8-37.3) weeks vs 34.9 (28.6-35.4) weeks, Z=－2.61, P=0.009], greater prolonged gestation [12.3 (9.7-13.9) weeks vs 7.3 (3.4-9.1) weeks, Z=－3.34, P=0.001], higher birthweight [2 430.0 (2 173.8-2 646.3) g vs 1 900.0 (1 372.5-2 435.0) g, Z=－3.06, P=0.002], lower incidence of adverse neonatal outcomes [16.7% (6/36) vs 36.7% (11/30), χ2=4.22, P=0.048] compared with the conservative group. Multivariate Logistic regression analysis showed that cerclage reduced the risks of preterm birth before 34 and 32 weeks [ aOR (95% CI)=0.083 (0.009-0.790) and 0.092 (0.009-0.939), both P<0.05]. However, cerclage did not reduce the risk of preterm birth in women with CL>1.5 cm or CL>1.0-≤1.5 cm (both P>0.05). Conclusion:Ultrasound- indicated cervical cerclage can reduce the risk of preterm birth before 34 and 32 weeks, prolong pregnancy, and improve perinatal outcomes in asymptomatic twin pregnancies with CL≤1.0 cm.

Objective To analyze the correlation between smoking and occurrence of intracranial artery stenosis.Methods From June 2015 to May 2016,a total of 10 711 inpatients with transient ischemic attack (TIA) or ischemic stroke from 20 basel hospitals of nationwide were enrolled using a cross-sectional study,76 patients with unknown smoking and smoking cessation years were excluded.Finally,a total of 10 635 patients were enrolled.Transcranial color coded sonography and/or transcranial Doppler were used evaluate the intracranial artery stenosis lesions.The basic risk factors for cerebrovascular disease (age,sex,smoking and smoking years,whether smoking cessation and years,hypertension,diabetes,hyperlipidemia,atrial fibrillation,and family history of stroke) were recorded.According to the different smoking years,the smoking years were divided into five groups:non-smoking,smoking time ≤10-year,11 to 20-year,21 to 30-year,and >30-year groups for trend chi square test.According to the different smoking cessation years in the smokers,the smoking cessation years were divided into four groups:non-cessation,cessation time 1 to 10-year,11 to 20-year,and >20-year groups for trend chi square test.The effects of different smoking years and different smoking cessation years on the occurrence of intracranial arterial stenosis were analyzed.Results The incidence of intracranial artery stenosis in the smokers (40.4%[1 433/3 547]) was significantly higher than that in the non-smoking patients (29.4%[2 085/7 088]).There was significant difference (χ2=128.850,P<0.01),and the incidence of cerebral infarction in the smokers (91.6%[3 250/3 547]) was significantly higher than the non-smokers (85.0%[6 027/7 088]).There was significant difference (χ2=92.328,P<0.01).Smoking was an independent risk factor for intracranial artery stenosis (OR,1.603;95%CI 1.456-1.765;P<0.01).With the increase of smoking years,the detection rate of intracranial arterial stenosis increased gradually (trend χ2=115.437,P<0.01).Whether giving up smoking had no significant effect on the incidence of intracranial artery stenosis in patients with ≥20 years of smoking (trend χ2=1.043,P=0.307).Conclusions Smoking is an independent risk factor for affecting intracranial artery stenosis;the risk of disease increases with the number of smoking years.Long-term smokers (≥20 years) cannot reduce the effect on intracranial artery stenosis,even if they give up smoking.

Objective To investigate the effect of serum lipid level on carotid artery stenosis in patients with ischemic cerebrovascular disease.Methods Using a multi-center cross-sectional study,10 711 consecutive inpatients with transient ischemic attack (TIA) or ischemic stroke diagnosed clearly in 20 stroke screening and prevention project base hospitals from June 2015 to May 2016 were enrolled.According to the results of carotid ultrasonography,1 560 patients with extracranial carotid artery stenosis rate≥50% screened were enrolled in the study.They were divided into a severe stenosis group (70%-99%) and a mild-moderate stenosis group (<70%).The distribution of total cholesterol (TC),triacylglycerol (TG),low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels in both groups of carotid stenosis patients were analyzed,and the quantitative classification was based on the normal range of serum lipids.The distributions of serum lipid levels in different grades in patients of both groups were compared with the non-parameter test.Results The incidence of dyslipidemia in the severe stenosis group was higher than that in the mild and moderate stenosis group.There was no significant difference between the two groups (54.4%[319/586]vs.48.3%[470/974],P<0.05).Dyslipidemia was an independent risk factor for severe carotid artery stenosis (OR,1.27,95% CI 1.24-1.30,P<0.01).The TC and LDL-C levels in patients of the severe stenosis group were significantly higher than those in the mild-moderate stenosis group (TC:3.98[3.31,4.82]mmol/L vs.3.91[3.31,4.53]mmol/L,LDL-C:2.48[1.86,3.14]vs.2.30[1.79,2.80];all P<0.01).With the increase of TC and LDL-C levels,there was significant differences between the severe stenosis group and the mild-moderate stenosis group (all P<0.05),and the proportions of TC >5.80 mmol/L (7.3%[43/586]vs.0.4%[4/974]) and LDL-C>3.12 mmol/L (26.3%[154/586]vs.10.0%[97/974]) in patients of the severe stenosis group were higher than those in the mild-moderate stenosis group (26.3%[154/586]vs.10.0%[97/974]).Conclusion The high LDL-C and TC levels may increase the incidence of severe carotid artery stenosis or occlusion.

Objective To investigate the differences of distribution characteristics and risk factors of large artery lesions in patients with ischemic cerebrovascular disease in different age groups in order to provide the basis for the prevention and treatment of stroke in different age groups.Methods From June 2015 to May 2016,a total of 10 711 consecutive inpatients with transient ischemic attack (TIA) and ischemic stroke from 20 centers nationwide were enrolled.Each 10 years was used as an age group from 40 years.All the patients were divided into 5 age groups.The differences of the different risk factors for cerebrovascular disease among the 5 groups were compared.All patients were separated by gender.The chi square test was used to compare the incidences of large artery stenosis of the intracranial and external and anterior and posterior circulation,and the number of vascular lesions in the same sex in different age groups.Results (1) The risk factors of elderly patients were mainly hypertension,diabetes mellitus,and atrial fibrillation (χ2=61.938,χ2=13.349,and χ2=55.940;all P<0.01).The smoking history,family history of cerebrovascular disease,and obesity were more frequent among the young and middle-aged people (χ2=131.505,χ2=7.298,and χ2=100.911,all P<0.01).(2) The linear trend chi square test results showed that the proportion of multivessel diseases in female and male extracranial arterial lesions increased gradually with the increase of age.(χ2=54.799,χ2=161.370,all P<0.01).The proportion of multivessel diseases in the intracranial artery in female decreased gradually (χ2=5.328,P=0.021),and that in male did not have obvious trend of change (χ2=0.289,P=0.591).(3) The linear trend chi square test results showed that the incidence of simple intracranial arterial stenosis in female and male intracranial arterial stenosis decreased gradually with the increase of age (χ2=20.090,χ2=42.351,all P<0.01),and the incidence of simple extracranial arterial stenosis increased gradually (χ2=40.311,χ2=90.698,all P<0.01).The incidence of both intracranial and extracranial artery stenoses increased gradually (χ2=12.077,χ2=45.887,all P<0.01).The incidence of simple posterior circulation vascular stenosis increased gradually in female (χ2=16.434,P<0.01),but that did not have obvious trend of change in male (χ2=1.701,P=0.192).The incidence of stenosis of both anterior and posterior arteries in female and male increased gradually (χ2=4.587,P=0.032;χ2=35.156,P<0.01).Conclusions The distribution of atherosclerotic lesions in ischemic cerebrovascular disease of the different age groups was different.No matter female or male patients,the majority of the young and middle-aged patients were intracranial artery lesions,and the elderly patients were mainly extracranial artery lesions.The majority of elderly women had posterior circulation artery lesions.Understanding the characteristics in patients with intracranial arterial lesion in different age groups will help to develop individualized stroke prevention and treatment strategies for the population of different age groups.
