Objective To investigate the relationship between the serum apolipoprotein B (ApoB)/ ApoA-Ⅰ ratio and intracranial artery stenosis in young patients with ischemic stroke.Methods Patients with ischemic stroke aged from 18 to 45 were enrolled in the study.Brain CT angiography was used to evaluate the degree of intracranial artery stenosis,and the concentrations of serum total cholesterol,triglyceride,highdensity lipoprotein cholesterol,low-density lipoprotein cholesterol,ApoA-Ⅰ,and ApoB were detected.The ratio of ApoB/ApoA-Ⅰ was calculated.The Demographic and clinical characteristics of the intracranial artery stenosis group and the non-intracranial artery stenosis group were compared.Multivariate logistic regression analysis was used to identify the independent risk factors for intracranial artery stenosis in young patients with ischemic stroke.Results A total of 161 young patients with ischemic stroke were enrolled,including 89 in the intracranial artery stenosis group and 72 in the non-intracranial artery stenosis group.The constituent ratios of diabetes mellitus (20.2％ vs.6.9％;x2 =4.641,P =0.032),smoking (47.5％ vs.15.2％;x2 =15.121,P=0.001),hyperlipidermia (56.1％ vs.48.6％;x2 =4.197,P=0.040),as well as the radios in serum high-density lipoprotein cholesterol (1.29 ± 0.30 mmol/L vs.1.65 ± 0.34 mmol/L;t =7.131,P=0.002),ApoA-Ⅰ (1.49 ± 0.65 g/L vs.1.63 ± 0.23 g/L;t =2.751,P =0.001),ApoB (1.49 ± 0.65 g/L vs.1.63±0.23 g/L;t=2.751,P=0.001),and ApoB/ApoA-Ⅰ ratio (1.49±0.65 vs.1.63± 0.23;t =2.751,P=0.001) had significant differences between the two groups.Multivariate logistic regression analysis showed that diabetes (odds ratio [OR] 3.052,95％ confidence interval [CI] 1.186-7.856;P =0.021),smoking (OR 2.997,95％ Cl 1.456-6.172;P =0.003),hyperlipidemia (OR 4.745,95％ CI 2.108-10.668;P =0.001),ApoB (OR 4.861,95％ CI 3.029-7.802;P=0.001),and ApoB/ ApoA-Ⅰ ratio (OR 5.684,95％ CI 2.215-14.584;P=0.002) were the independent risk factors for intracranial artery stenosis in young patients with ischemic stroke,while HDL-C (OR 0.561,95％ CI 0.354-0.888;P=0.014) and ApoA-Ⅰ (OR 0.065,95％ CI 0.010-0.409;P=0.004) were the independent protective factors.After adjustment for hypertension,diabetes,smoking,hyperlipidemia,HDL-C,ApoA-Ⅰ,and ApoB,ApoB/ApoA-Ⅰ ratio was still an independent risk factor for intracranial artery stenosis in young patients with ischemic stroke (each increase of 1 standard deviation,OR 4.255,95％ CI 2.348-7.711;P=0.001).Conclusion ApoB/ApoA-Ⅰ ratio is an independent risk factor for intracranial artery stenosis in young patients with ischemic stroke.

OBJECTIVE:To observe the effects of parecoxib preemptive analgesia combined with postoperative epidural analgesia on hip replacement and immune function. METHODS:Totally 86 patients undergoing unilateral hip replacement selected from Xining Third People's Hospital during Jan. 2014-Jun. 2016 were divided into observation group and control group according to random num-ber table,with 43 cases in each group. Two groups underwent unilateral hip replacement under spinal epidural anesthesia. Observation group was given Parecoxib sodium for injection 40 mg intravenously 30 min before the end of surgery. Control group was given con-stant volume of normal saline intravenously. Both groups were given epidural analgesia pump(Ropivacaine hydrochloride injection 150 mg+Ondansetron hydrochloride injection 16 mg+Dezocine injection 10 mg,added into normal saline to 100 mL)after surgery with dripping speed of 2 mL/h and patient-controlled time of 15 min. The hemodynamic indexes,analgesic effect,T lymphocyte subsets and NK cells levels were compared between 2 groups at different time points as well as the occurrence of ADR after surgery. RE-SULTS:Two patients of observation group and one patient of control group withdrew from the study. Before surgery,there was no sta-tistical significance in MAP and HR between 2 groups(P>0.05);12,24 h after surgery,MAP and HR of control group were signifi-cantly increased and higher than observation group,with statistical significance(P<0.05). There was no statistical significance in MAP and HR of observation group at different time points compared to before treatment;there was no statistical significance in MAP and HR between 2 groups immediately after surgery,48 h after surgery(P>0.05). There was no statistical significance in VAS score between 2 groups immediately after surgery(P>0.05);6,12,24,48 h after surgery,VAS scores of observation group were signifi-cantly lower than those of control group,with statistical significance(P<0.05). There was no statistical significance in CD3+,CD4+, CD4+/CD8+and NK cells levels between 2 groups before surgery(P>0.05). CD3+,CD4+and NK cells levels of 2 groups immediately after surgery,CD3+,CD4+,CD4+/CD8+ and NK cells levels of 2 groups at 12,24 h after surgery,CD3+and CD4+of control group at 48 h after surgery all changed significantly;CD3+,CD4+,CD4+/CD8+and NK cells levels of observation group at 12,24 h after sur-gery were significantly higher than those of control group,with statistical significantly(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:The parecoxib preemptive analgesia combined with postopera-tive epidural analgesia shows good analgesic effect for hip replacement patients,keeps their hemodynamics stable and protects immune function to certain extent with good safety.

Objective To explore the dynamic changes of D-dimers during pregnancy and early puerperium (within 3 days postpartum). Methods A retrospective study was performed among 8 367 healthy women who had term singleton delivery in Women′s Hospital, School of Medicine, Zhejiang University from January 2007 to December 2014. D-dimers concentrations during pregnancy and early puerprium of all the cases were collected. Data of 21 065 D-dimers tests were assigned to 5 groups according to the time of sampling, including early pregnancy (≤12 gestation weeks), middle pregnancy (12-28 gestation weeks), late pregnancy (>28 gestation weeks), 1 postpartum (within 48 hours postpartum) and 2 postpartum (48-72 hours postpartum). The D-dimers concentrations in different groups were compared. The effect of delivery mode on D-dimers of early pureperium was analyzed. The correlation between D-dimers and the thromboembolic disease was also explored. In this study, Student′s t-test and Wilcoxon rank sum test were used for statistical analysis. D-dimers concentration≤0.5 mg/L was used as the normal range. Results (1) D-dimers concentrations during pregnancy were higher than the non-pregnant women (P<0.01), but there was no statistical difference between early pregnancy and late pregnancy (P=0.820). D-dimers concentration in the 1 postpartum group was higher than that of early pregnancy group or late pregnancy group (P<0.01). But in the 2 postpartum group, it was lower than early pregnancy, late pregnancy and 1 postpartum groups. (2)D-dimers in cesarean section cases was significantly higher than in vaginal delivery cases in each period of pregnancy and early pueprium.(3)The 95%CI of D-dimers in early pregnancy, late pregnancy, 48 hours after vaginal delivery, 48-72 hours after vaginal delivery, ≤48 hours after cesarean section, 48-72 hours after cesarean section were 0.58-8.28, 0.47-11.52, 1.04-9.59, 0.87-5.22, 1.07-11.58 and 1.00-6.23 mg/L, respectively.(4)In 6 cases with thromboembolic disease, D-dimers was 6.89-19.89 mg/L, with the mean value of 13.66 mg/L. It was significantly higher than normal range. In 3 cases, all after cesarean section, with lower extremity vein thrombosis within 48 hours postpartum, the D-dimers concentrations, 9.77, 8.65 and 6.89 mg/L respectively, were in the 95%CI of the study population after cesarean section. Conclusions D-dimers concentration of 0.5 mg/L is not suitable for venous thromboembolism screening during pregnancy. D-dimers concentration in pregnancy and early puerprium is higher than non-pregnancy. It increases in the very early period postpartum and decreases with time. D-dimers should not be a routine screening test to exclude thromboembolic disease in pregnant women without high risk factors and clinical manifestation of thromboembolic disease.

ObjectiveTo evaluate the clinical outcomes of anterior lumbar discectomy and interbody fusion with cage under laparoscopic assistant.MethodsFrom January 2006 to June 2009,37 cases with degenerative low back pain were entered the study,including 22 males and 15 females with an average age of 43.7 years(range,16-55).The responsible discs were determined according to the three dimensional computed tomography of artery and vein angiography of anterior lumbosacral spine and discography,including L5S1 in 21 cases,L4-5 in 11,L3-4 in 2,L2-3 in 2,and L1-2 in 1.All cases underwent anterior lumbar discectomy and interbody fusion with cage under laparoscopic.ResultsThe operation time was 100 min in average (range,60-140),the blood loss was 120 ml in average(range,50-300).There was no case with severe complications of retrograde ejaculation and injury of great vessels or nerves.Delayed intestinal obstruction was discovered in two intraperitoneal route patients.The average follow-up time was 18.7 months(range,6-35).According to the back pain grading criteria of Chinese Medical Association Orthopedics Society of Spine Group,the results were excellent in 23 patients,good in 11,and fair in 3.The interbody fusion was obtained in 3 months later in 23 cases and 6 months later in 12 cases.Cage subsidence occurred in 2 cases in 6months after operation,in which the height loss of intervertebral space was 1.3 mm and 1.9 mm,but no obvious symptoms of discomfort.No fixation displacement or loosening occurred.ConclusionThe anterior discectomy and interbody fusion by internal fixation with laparoscopic technique is feasible with low complications rate,less trauma and shorter bedtime.Postoperative ileus by abdominal approach is relatively common.The surgeons experience and the anatomy of artery and vein of anterior lumbosacral spine should be considered before the choice of surgical approach.

Objective To determine if the cardiac index (CI) measured with arterial pressure-based cardiac output (APCO) agrees with that measured with pulmonary artery catheter (PAC) during cesarean section in parturients with congenital heart disease and severe pulmonary hypertension.Methods Thirty parturients with congenital heart disease and severe pulmonary hypertension,scheduled for elective cesarean section,were enrolled in the study.APCO and PAC were used for cardiac output and other parameters of hemodynamics monitoring during operation in all patients.Continuous epidural anesthesia was performed.CI was recorded immediately before epidural administration (T1),at 5 and 10 min after epidural administration (T2-3),immediately before delivery (T4),and at 2 and 5 min after delivery (T5-6).The correlation was tested by Pearsone correlation analysis.CI derived from APCO and PAC was compared by Bland-Altman analysis for agreement.Results CI measured with PAC was significantly higher than that measured with APCO (P ＜ 0.05).Compared with the baseline value at T1,no significant difference in CI measured with PAC and APCO was found at T11-T4 and T6 (P ＞ 0.05),and CI measured with PAC and APCO was significantly increased at T5 (P ＜ 0.05).Bland-Ahman analysis showed poor agreement between CI measured with the two methods.The correlation analysis showed that there was positive correlation between CI derived from the two methods at T1-6 (the correlation coefficient was 0.93,0.95,0.94,0.89,0.96 and 0.91 at T1-6,respectively,P ＜ 0.05).Conclusion CI value obtained with APCO agrees poorly with that obtained with PAC during cesarean section in parturients with congenital heart disease and severe pulmonary hypertension,but agrees well in monitoring the changing trend of CI.

OBJECTIVETo observe the effect of Bushen Huoxue Recipe (BSHXR, a Chinese medicine recipe for Shen reinforcing and blood circulation activating) on the levels of urinary albumin, interleukin-6 (IL-6), transforming growth factor-beta1 (TGF-beta1), and monocyte chemotactic protein-1 (MCP-1) in chronic nephritis patients of Shen-deficiency blood-stasis syndrome.

METHODSForty-five patients were blocking assigned randomly to two groups, fifteen patients in the control group and thirty in the treatment group. All orally took Monopril 10 mg, once daily. But BSHXR was given additionally to patients in the treatment group after decocting,one dose per day (taken in two times). The treatment course for both groups was eight weeks. Besides, a normal control group consisting of six healthy subjects from health examination of Shuguang Hospital was set up. The 24-h urinary albumin and contents of TGF-beta1, IL-6 and MCP-1 in urine of all subjects were observed.

RESULTSCompared with before treatment the 24-h urinary albumin was obviously reduced in the treatment group, showing significant difference (P<0.01). The urinary 24-h albumin decreased in the control group, with statistical significance (P<0.05). Statistical difference existed between the treatment group and the control group after treatment (P<0.01). Compared with before treatment, urinary levels of IL-6, TGF-beta1, and MCP-1 were all down-regulated in the treatment group and the control group after treatment (P<0.01), and the decreasing of IL-6 and TGF-beta1, levels was more significant in the treatment group statistically (P<0.05).

CONCLUSIONSBSHXR could attenuate the albuminuria in patients of chronic nephritis. Its mechanism might be possibly correlated with its down-regulation of IL-6, TGF-beta1, and MCP-1 levels.
