Objective To investigate the effect of early low-glucocorticoid on hemodynamics and prognosis in the patients with septic shock.Methods Sixty patients with septic shock failing in active fluid resuscitation and vasoactive drugs in our hospital from June 2013 to August 2015 were selected and divided into the control group,early-hormone group and late-hormone group.MAP,HR,PO2/FIO2 and serum lactic acid levels were monitored in all selected patients before treatment and at 12,24,48 h after treatment.Apache Ⅱ,SOFA scores were assessed before treatment and on 1,3,7 d after treatment.The ventilation time,ICU stay time,hospital stay time and intravenous use time of vasoactive agents(VDNT) were recorded.Results The Apache Ⅱ scores and SOFA scores on 3,7 d after treatment in the early-hormone group were significantly decreased compared with the late-hormone group and control group (P＜0.05).MAP and HR at 24,48 h after treatment in the early-hormone group were significantly improved compared with the late-hormone group and control group (P＜0.05).The level of serum lactic acid at 12,24 h after treatment in the early-hormone group and late-hormone group were obviously lower than that in the control group,the levels of serum lactic acid at 12,24 h after treatment in the early-hormone group were obviously lower than those in the late-hormone group (P＜ 0.05).PO2/FIO2 at 12 h after treatment in the early-hormone group and late-hormone group were obviously better than that in the control group,and PO2/FIO2 at 12 h after treatment in the early-hormone group was obviously better than that in the late-hormone group(P＜0.05).The ventilation time,ICU stay time,hospital stay time and VDUT in the early-hormone group were significantly shortened compared with the late-hormone group and control group.The ventilation times,ICU stay time and VDUT in the latehormone group were significantly shortened compared with the control group (P＜0.05).Conclusion Early using low-dose glucocorticoid may restore hemodynamics more quickly,protects the organ function and improves the prognosis in the patients with septic shock.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

Objective:To analyze morphological character of lateral tibial plateau fracture fragment, and its correlation to the presence of a meniscus injury in tibial plateau fractures.Methods:A total of 79 consecutive patients of the simple lateral tibial plateau fractures from July 201 1 to July 2015 were inclu-ded in this study,with 65 males and 14 females with an average age of (34.3 ±7.2)years and 22-61 years.According to Schatzker classification,21 cases were of Type Ⅰ,41 cases Type Ⅱ,and 17 cases Type Ⅲ.The characteristics of lateral tibial plateau fractures were evaluated by plain X-ray and magnetic resonance imaging (MRI ).The type and severity of meniscus injury were diagnosed by MRI scan. Three-dimensional measurements of the lateral fragment width (LFW),the lateral plateau depression (LPD),the coronal angulation of lateral fragment (CALF),and tibial plateau widening (TPW)were measured with Picture Archiving and Communication Systems(PACS)software.The patients with and without meniscus injuries were divided into different groups and analyzed respectively.Comparison of the above measurements between the two groups was analyzed by independent t test.Results:In all the 79 lateral tibial plateau fracture patients,26 cases (32.9%)of meniscus injuries were detected by MRI. Among all the meniscus injury cases,3 were of SchatzkerⅠ,16 SchatzkerⅡ,and 7 SchatzkerⅢ.In meniscus intact group,the average LFW was (22.0 ±2.8)mm while in meniscus injury group it was (21.3 ±3.3)mm (t =-1.008,P =0.317).The average LPD of non meniscus injury group was (5.4 ±2.8)mm,while in meniscus injury group was (8.7 ±2.8)mm (t=4.98,P=0.001).The average CALF of the two groups were 9.1°±6.1°and 10.6°±7.1°,and there was no significant dif-ference between the two groups (t=0.38,P=0.831).The average TPW was (3.0 ±1.1)mm,and (4.8 ±1 .7 )mm of the two groups.There were significant differences between the two groups (t =5.216,P=0.001).Conclusion:There was no obvious correlation between the LFD and meniscus inju-ry.The CALF of lateral tibial plateau fracture had no significant correlation with meniscus injury either. The degree of LPD and TPW may indicate injury of the meniscus in tibial plateau fractures.

OBJECTIVEThe best approach for blood pressure (BP) measurement in children remains controversial, especially on the choice of Korotkoff phase 4 (K4) vs. Korotkoff phase 5 (K5) for diastolic BP (DBP) and to compare the differences between K4 and K5 in school-aged children and their predictions to hypertension in adult.

METHODSThe "Beijing children and adolescents BP study" cohort population consisted 2505 school-aged children aged 6 to 17 at baseline survey in 1987, when datum of systolic BP (SBP), DBP measured using K4 and K5, were collected respectively. Among them, 412 individuals with 220 males and 192 females at age of 23-37 years old, were successfully followed up and invited to take part in a clinical examination including anthropometric measurements, SBP and DBP recordings, and a questionnaires in 2005. Method for the BP measurements at both baseline and followed-up was by auscultation with a standard sphygmomanometer. Child hypertension at baseline was diagnosed according to the age-specific cutoffs recommended by the World Health Organization in 1996 (WHO 1996). Adult hypertension was diagnosed according to the China Guideline for Hypertension Prevention and Control issued in 2005. Partial correlation coefficients were calculated to describe the association of K4 and K5 in childhood with SBP and DBP level in adulthood. Multivariate logistic regression analysis was conducted to examine the impact of choice of K5 and K4 as DBP in childhood on prediction to the hypertension in adulthood. Potential confounders such as gender and adult-height were controlled for.

RESULTSAt baseline, the prevalence rates of hypertension were 5.0% with DBP measured using K4, and 2.4% with DBP measured using K5, respectively. The geometric mean difference value of K4 minus K5 (K4 - K5) was (10.1 +/- 1.7 mm Hg) (1 mm Hg = 0.133 kPa) for the 2505 school-aged children, and decreased as age increased. There was no significant difference regarding the values of K4 - K5 between males and females in all age groups except for children who at pubertal stage. The distribution of K4 - K5 value across age groups was statistically significant (P < 0.001), 59.6%, 60.5%, 56.3% and 45.1% of children who aged 6-9 years, 10-12 years, 13-15 years, and 16-17 years with their K4 - K5 value over 10 mm Hg. K4 in childhood was better correlated to both SBP and DBP in adulthood than K5. In general, K4 seemed to be superior to K5 in predicting hypertension in adulthood. The odds ratios of hypertension in adulthood were 1.69 (95% CI: 1.11-2.00), 1.45 (1.05-2.02), 2.18 (1.37-3.47), and 1.66 (1.07-2.59) with each 5 mmHg increasing of K4 measured in children aged 6-9 years, 10-12 years, 13-15 years, and 16-17 years, respectively. The agreement diagnosis between child hypertension and adult hypertension was higher for childhood DBP measured using K4 (20.2%) than that using K5 (12.8%).

CONCLUSIONThere was significant difference between K4 and K5 in Chinese children and adolescents. Choice of diastolic Korotkoff blood pressure could affect DBP tracking from childhood into adulthood. K4 seemed superior to K5 when using auscultator technique to measure DBP.

OBJECTIVETo analyze the correlation between myocardial ischemia and carotid atherosclerosis in hypertensive patients.

METHODSThe clinical data were collected from 85 hospitalized hypertensive patients admitted between May 2005 and September 2008 without the complication of coronary artery disease as confirmed by cardiac computed tomographic angiography (CTA). According to the results of treadmill exercise test, the patients were divided myocardial ischemia group and ischemia-free group. Univariate and multivariate analyses were used to screen the risk factors of myocardial ischemia. The correlations were analyzed between myocardial ischemia, common carotid artery intima-media thickness (IMT), Crouse score of the carotid plaque, thickness of the intraventricular septum and left artrium. The receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of IMT and Crouse score in predicting the presence of myocardial ischemia in hypertensive patients.

RESULTSCarotid plaque formation was identified as the major risk factor of myocardial ischemia in hypertensive patients (OR=4.982, P=0.004). The incidence of myocardial ischemia in the hypertensive patients with carotid plaques was significantly higher than that in the patients without the plaque (Chi2=9.317, P=0.002). Myocardial ischemia in hypertensive patients was positively correlated to the thickness of the intraventricular septum (r=0.362, P=0.001) and left artrium (r=0.298, P=0.009), and the IMT of the common carotid artery was positively correlated to the thickness of the intraventricular septum (r=0.231, P=0.045). The area under cure (AUC) of the ROC curve of Crouse score was 0.726-/+0.061 in predicting the presence of myocardial ischemia in the hypertensive patients (P=0.001), and that of IMT was 0.682-/+0.061 (P=0.006).

CONCLUSIONCarotid plaque formation is the major risk factor of myocardial ischemia in hypertensive patients and shows a positive correlation to the onset of myocardial ischemia, but both the common carotid artery IMT and the Crouse score of the carotid plaque are not accurate markers for predicting myocardial ischemia in patients with hypertension.

OBJECTIVETo investigate the feasibility and safety of autologous peripheral blood hematopoietic stem cell transplantation (auto-PBHSCT) and its therapeutic effect on refractory rheumatism among preschool children.

METHODSThree boys with juvenile rheumatoid arthritis (JRA), juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM) respectively, 3 to 6 years old with the mean age of 5 years with 3.5 to 22 months course of disease with 14 months on average, received auto-PBHSCT. Their conditions were so severe that conventional therapy failed to control the diseases. The changes of both clinical manifestations and immunologic indexes were observed before and after transplantation with long term following up at specialty clinic of rheumatism.

RESULTThe time when neutrophil count >or= 0.5 x 10(9)/L in the 3 children was days +9, +13 and +11 respectively, that of platelet count >or= 20 x 10(9)/L was days +14, +18 and +13 respectively. The cellular immune function remained abnormal with CD4 cells at a low level and CD4/CD8 being inverted. As to the JDM child, the skin rash had disappeared and his muscle tone was improved to grade 5 within one month after the transplantation. The EMG and serum creatase level returned to normal and muscle MRI findings were improved greatly within 2 months after the transplantation. As to the JSLE child, skin rash and proteinuria had disappeared, MRI of brain showed that the pathological changes had been absorbed and EEG returned to normal 3 months after the transplantation, all the autoantibodies turned to negative within 8 months after transplantation. As to the JRA child, the arthritis had been improved remarkably within 3 weeks after auto-PBHSCT. There was no swelling of joints nor movement limitation 3 months post transplantation. The steroids and immunosuppressive drugs were discontinued post transplantation. Cushing syndrome disappeared. Their body heights increased by 10 to 15 cm in the past 18 months, and they all returned to school. There was no relapse during follow-up periods of 25 - 27 months.

CONCLUSIONThe therapy with auto-PBHSCT for refractory rheumatism among preschool children was remarkably effective in a short-term, yet the safety and long-term effect still need to be further studied.
