Objective To investigate the normal ranges of RET-He and reticulocyte grouping parameters of healthy adults in Wenzhou. Methods A total of 1 000 samples from healthy adults were collected in Wenzhou from August 2008 to February 2010. There were 506 males and 494 females. The individuals were stratified based on age into three groups:20 to 40-year-old group (n = 341 ), ＞40 to 60-year-old group (n =316), and ＞60-year-old group (n =343). All blood samples were drawn in EDTA-K2 anticoagulated blood. Peripheral RET-He and reticulocyte grouping parameters ( IRF, LFR, MFR, HFR)were determined by Sysmex XE-2100 automated hematology analyzer. The instrument was calibrated and validated before testing All specimens were analyzed within 2 hours. RET-He, RET absolute value and RET percentage were normal distribution, the normal range was established by using ((x)-1.96s,(x)+ 1.96 s)method. IRF, LFR, MFR and HFR data were skewed distribution,the normal range was established by using (P2.5 ,P97.5 )percentile method. Results The mean and normal range of RET-He were (33.91 ± 1.77) pg and (30.44 - 37.38) pg in male, (33.97 ± 1.85) pg and (30.34 - 37.60) pg in female,respectively. There was no significant difference between the two groups ( t =-0.533, P＞0.05 ). The mean and normal range of RET absolute value were (0.051±0.023) × 1012/L and (0.006 -0.096)×1012/L in male,which were (0. 037 ±0. 026) × 1012/L and (0 -0. 088) × 1012/L in female, there was significant difference between the two groups ( t = 8. 409, P ＜ 0. 05 ) . The mean and normal range of RET percentage in male were(1.041 ±0.459)% and (0. 141 -1.941)% , and in female were (0.869±0.603)% and (0-2. 051 )%, which showed significant difference (t =5.074,P ＜0. 05). The normal ranges of LFR,MFR,HFR,IRF in male were 0. 951 (0.866 -0.988) ,0.046(0.010 -0.114) ,0. 003(0 -0.023) ,0. 050(0.012-0.134), and in female were 0.096(0.880 -0.991) ,0.039(0.008 -0.113) ,0.002(0-0.016) ,0.040(0.009-0.121), respectively. There were significant differences between the two groups (Z values were -5.044, -4.793, -3.559, -5.075, respectively,all P＜0.05). The means of RET-He in 20 to 40-year-old group, ＞40 to 60-year-old group, ＞ 60-year-old group and all age group were (33.38±1.49),(34.36 ±1.46), (34.12±2.21) and (33.94 +1.81) pg, respectively. The normal ranges were(30.46-36.30), (31.50 -37.22), (29.79 - 38.45) and (30.39 - 37.49) pg, which showed statistical difference( F =28. 072,P ＜0. 05). In addition, the normal range of RET-He in 20 to 40-year-old group was lower than that of ＞ 40 to 60-year-old group and ＞ 60-year-old group ( q values were 9. 970, 7. 791,respectively, P＜0. 05). The normal ranges of LFR, MFR, HFR, IRF in ＞ 60-year-old group were 0.961(0. 878 -0. 992) ,0. 037(0. 007 -0. 105 ) ,0. 002(0 -0. 020) and 0. 039(0. 008 -0. 117) ,while they were 0.953(0. 867 -0.990), 0.045(0.009 -0. 116) ,0.003(0 -0.019) ,0. 050(0. 010 -0. 133) in 20 to 40 -year-old group , and 0. 951 (0.855 -0.989) ,0.047 (0.010 - 0.133 ) ,0.003 ( 0-0.020), 0.049 (0.011-0.149)in ＞40 to 60-year-old group, which showed statistical difference (Z values were -3. 949, -4.236,-4. 373, -4. 973, - 2. 747, - 3. 275, - 3.901, - 4. 185, respectively, all P ＜ 0. 05). There was nodifference between male and female for RET-He, the same normal ranges could be used, but there was significant difference between different age groups. LFR, MFR, HFR and IRF were statistically different between different age groups and different sex groups. The normal ranges should be established by gender and age. Conclusion The normal ranges of RET-He and reticulocyte grouping parameters about healthy adults in Wenzhou are established, which plays an important role in clinical value of RET parameters.

Objective To explore the clinical effect of corticosteroids combined with Chinese medicine sequential therapy of Guishao Dihuang pill and Yupingfeng granules on children nephrotic syndrome (NS) with yin deficiency of liver and kidney.Methods Fifty patients (the loss of children during the course of treatment were not included in the statistical analysis) with definitely diagnosed NS accompanied by yin deficiency of the liver and kidney admitted to the First Affiliated Hospital of Gannan Medical University from January 2012 to June 2016 were enrolled,and they were divided into control group and observation group by random number table,25 cases in each group.Conventional treatment of western medicine and long-term treatment of corticosteroids were given to the two groups.In addition,sequential therapy of Guishao Dihuang pills and Yupingfeng granules was given to the observation group on the bases of conventional treatment.The changes of platelet aggregation rate (PAT),cholesterol,cortisol,T cell subsets CD3,CD4,CD4/CD8 were observed before and after treatment for 8 weeks and 6 months,then the clinical efficacy and infection,etc.complications were compared between the two groups.Results There were no statistical significant differences in cholesterol,cortisol and curative effect compared between the two groups before treatment and after treatment for 8 weeks and 6 months (all P ＞ 0.05).Mter treatment for 8 weeks and 6 months,the PAT,cholesterol,cortisol of two groups were significantly decreased compared with those before treatment,while CD3,CD4 were obviously higher than those before treatment,and the degrees of changes of PAT,CD3,CD4 in the observation group were more remarkable than those of the control group [PAT:treatment after 8 weeks was (63.01 ± 6.99)％ vs.(66.62 ± 4.65)％,treatment after 6 months was (51.42 ± 7.74)％ vs.(57.01 ± 6.77)％,CD3:treatment after 8 weeks was 0.56 ± 0.06 vs.0.52± 0.06,treatment after 6 months was 0.61 ± 0.05 vs.0.58 ± 0.03,CD4:treatment after 8 weeks was 0.33 ± 0.06 vs.0.30 ± 0.05,treatment after 6 months was 0.39 ± 0.05 vs.0.33 ± 0.06,all P ＜ 0.05].CD4/CD8 ratio was significantly higher in observation group after treatment for 8 weeks and 6 months than those before therapy (1.68 ± 0.76,1.82 ± 0.95 vs.1.16 ± 0.67,both P ＜ 0.05);the number of patients with infection in observation group was obviously lower than that of the control group (86 cases vs.175 cases,P ＜ 0.05).Conclusions The therapeutic effect of corticosteroids combined with Chinese medicine sequential therapy of Guishao Dihuang pills and Yupingfeng granules for treatment of children NS with yin deficiency of the liver and kidney is better than that of using western medicine therapy alone,as the combined sequential therapy has good effects on reduction of infection,anti-thrombosis and elevation of immunity.

Objective To analyze the expression of synaptophysin (SY) in hippocampal dentate gyrus of rats with hypoxic-ischemic brain damage(HIBD) after the injection of bone marrow stromal cells(BMSCs) and its supernatant into the lateral ventricle and to explore the mechanism of potential effects. Methods Eighty 7-day-old sprague-dawley(SD) rats were randomly divided into sham group, control group, cell group and supernatant group, with 20 rats in each group. The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia. One week later, control group was injected with 0.01 mol/L PBS via the left ventricle. Meanwhile, cell and supernatant group were injected with BMSCs and supernatant harvested from BMSC culture, respectively, via the same route. For spam group, the left carotid arteries were separated but not ligated, and no hypoxia treatment was imposed on this group. They also received 0.01mol/L PBS injection one week post surgery. After 8 weeks, the expression of SY in the dentate gyrus of rats was measured. Results Compared with sham group, model group showed significantly lower IOD (integral optical density) of SY positive material in the dentate gyrus(P < 0.05). Compared with model group, supernatant group and cell group exhibited significantly increased IOD values (P < 0.05), but there was no significant difference between cell group and supernatant group (P > 0.05). Conclusions BMSCs and supernatant injected via the lateral cerebral ventricle can increase SY expression in the hippocampal dentate gyrus of HIBD rats and promote synapse formation. The mechanism of this effect may be related to cytokine secretion by BMSCs which promotes synapse formation.

Objective To evaluate the value of neck blood vessel colored doppler ultrasound (NBVCDU) and magnetic resonance angiography (MRA) to extracranial carotid artery stenosis in patients with transient ischemic attack (TIA).Methods After implementing NBVCDU and MRA examinations at the same time,45 TIA patients with at least one examination showing arteriostenosis in extracranial section were chosen to carry out cerebral digital subtraction angiography( DSA ),then the stenosis rate was calculated by American symptomatic carotid endarterectomy trial (NASCET) method.Results Regarding DSA as the gold standard,for 45 TIA patients that having 180 arteriostenosis in extracranial section, sensitivity,specificity,accuracy of NBVCDU examination was 93.51% ,95.15% ,94.44%, Kappa = 0.735; sensitivity,specificity,accuracy of MRA was 92.21% ,94.17% ,93.33% , Kappa =0.681; sensitivity,specificity,accuracy of NBVCDU combined with MPA was 97.40% ,99.03% ,98.33%, Kappa = 0.872.Conclusions The sensitivity and accuracy of arteriostenosis in extracranial section by NBVCDU examination is higher than that by MRA, and it is suitable in the crowd primary examination.NBVCDU combined with MRA has shown good consistence with DSA for diagnosing arteriostenosis in extracranial section,but can't replace DSA comlpetely.

Objective To explore the main influential factors of bronchodilation test positive results in mechanically ventila-ted patients with chronic obstructive pulmonary disease(COPD).Methods A total of 55 inpatients with acute exacerbation of COPD(AECOPD)receiving the invasive ventilation from June 2015 to March 2016 were collected.The accurate respiratory mechan-ics monitoring was performed before and after using the bronchodilator.The airway resistance reduction over 12% after inhaling bronchodilator served as the judgment criteria,the patients were divided into the bronchodilation test positive or negative groups, then the influential factors were compared and statistical analysis was performed.Results Twenty-nine cases(52.7%)showed the positive reaction and 26 cases(47.2%)were negative.After univariate analysis,results of heart rate,SaO2,fungal infection,horm-onotherapy,CKMB,lactic acid and BNP were brought into the multivariable Logistic regression analysis(P< 0.1).The analysis found that fungal infection was an independent factor affecting the results of the bronchodilation test(P<0.05).Conclusion Fun-gal infection is an independent influential factor of the bronchodilation test positive in COPD patients receiving invasive ventilation.
