Objective To investigate the significance of blood donation in preventing metabolic syndrome (MS)by analyzing the changes of the blood pressure and the related biochemical indexes before and after blood donation in the blood donors with high risk of MS.Methods The blood specimens of 102 blood donors,aged 45 -55 years old with the systolic blood pressure of 110 -140 mmHg and the diastolic blood pressure of 75 -90 mmHg,the body mass index> 24 kg/m2 ,were selected as the subjects.The blood pressure,heart rate,iron reserves,blood glucose,blood lipids,and the other indicators were determined before blood donation. All the above indicators were tested again on 42 d after blood donation.Results The blood pressure,iron reserves,blood glucose and LDL/HDL ratio after donation showed significant changes compared with before blood donation(P <0.05 ).Conclusion The changes of the MS related blood indexes exist before and after blood donation,blood donation has a certain significance for preven-ting MS in the blood donors with high risk of MS.

Objective To explore the clinical significance of urinary leukotriene E4(LTE4) in children with respiratory syncytial virus(RSV) bronchiolitis.Methods Forty infants with bronchiolitis were enrolled for the identification of RSV-Ag from the nasopharyngeal secretions.Forty cases who were found to be positive of RSV were put into RSV bronchiolitis group.According to the severity of illness,the infants in RSV bronchiolitis group were separated into 2 subgroups:mild illness group (24 cases) and moderate illness group (16 cases).Thirty healthy children were chosen as healthy control group.Urine of the patients in RSV bronchiolitis group was collected in acute phase (on the 1st day) and recovery phase (on the 7th day after the admission).Urine of children in control group was collected .Enzyme-linked immunosorbent assay was used to assay the level of urinary LTE4.Results The levels of LTE4 in healthy control group (M,Q) were 1.28 pmol?mmol-1,1.72 pmol?mmol-1,while the levels of LTE4 in acute phase in RSV bronchiolitis group (M,Q were 30.52 pmol?mmol-1,23.56 pmol?mmol-1,and the levels of LTE4 in recovery phase in RSV bronchiolitis group (M,Q) were 3.98 pmol?mmol-1,3.43 pmol?mmol-1.Urinary LTE4 levels in acute phase in RSV bronchiolitis group were significantly higher than those in healthy control group (P

OBJECTIVE:To observe the clinical efficacy and safety of enhanced immunosuppressive therapy in the treatment of refractory nephrotic syndrome (RNS). METHODS:Totally 76 RNS patients were selected from 2 hospitals during Jan. 2012-Mar. 2015,and then divided into control group and observation group according to random number table,with 38 cases in each group. Two groups were given Prednisone acetate tablet 50 mg,qd;decreasing to 15 mg,qd,after urine protein returned to normal. Based on it,control group was given Leflunomide tablets 50 mg,qd;decreasing to 20 mg,qd,3 days later. Based on con-trol group,observation group was additionally given Mycophenolate mofetil dispersible tablet 750 mg,bid;decreasing to 500 mg, qd,3 months later. Both groups were treated for 6 months. Clinical efficacies,follow-up recurrence rate as well as renal function in-dexes and inflammatory cell factors before and after treatment,and the occurrence of ADR were compared between 2 groups. RE-SULTS:The total response rate of observation group(92.11%)was significantly higher than control group(73.68%),and fol-low-up recurrence rate(5.26%)was significantly lower than control group(23.68%),with statistical significance(P<0.05). Be-fore treatment,there was no statistical significance in renal function indexes or inflammatory cell factors between 2 groups(P>0.05). After treatment,24 h urinary protein quantification,urinary IL-6 and IL-8 levels of 2 groups decreased significantly,while the content of serum protein increased significantly;the observation group was significantly better than the control group,with sta-tistical significance(P<0.05). There was no statistical significance in the content of serum creatinine between 2 groups before and after treatment(P>0.05). The incidence of ADR in the control group and the observation group was 34.21% and 44.74% respec-tively,without statistical significance between 2 groups(P>0.05). CONCLUSIONS:Enhanced immunosuppressive therapy in the treatment of RNS can improve renal function,reduce inflammatory reaction and long-term recurrence risk,and have good therapeu-tic efficacy and safety.

Objective Hyperglycemic clamp technique (HGCT) was performed to evaluate the effect of short-term intensive insulin therapy on the first and second-phase (1PH and 2PH) insulin secretion and maximum insulin secretion (MIS) in newly diagnosed type 2 diabetics. Methods Twelve volunteers with normal glucose tolerance (NC group) and six newly diagnosed type 2 diabetics (DM group) were included and HGCT was performed to assess the function of pancreatic islet beta cell. Then HGCT was repeated in the 6 patients following two week intensive insulin therapy. Results The levels of secreted insulin in 1PH, 2PH and MIS were 257?36 mU/L, 63?5 mU/L and 80?5 mU/L in NC group respectively, and 95?19 mU/L, 34?9 mU/L and 39?12 mU/L in DM group respectively. 1PH insulin secretion was significantly improved in the diabetics following 2 week treatment compared with that before the treatment (135?27 mU/L vs 95?19 mU/L, P=0.01). The insulin secretions in 2PH and MIS were slightly increased (40?9 mU/L vs 34?9 mU/L, P=0.09, 46?11 mU/L vs 39?12 mU/L,P=0.08, respectively). Conclusions Short-term intensive insulin therapy can improve the insulin secretions significantly in 1PH and slightly in 2PH and MIS in newly diagnosed type 2 diabetics.

Thirty cases of peripheral facial palsy were treated with the comprehensive therapy, and 30 cases of peripheral facial palsy were treated with shallow electro-acupuncture as control. The results showed that the cure rate in treatment group was higher than that in the control group(P＜ 0.05), and no significant difference was found in effective rate between two groups.

Objective To explore the role of extracellular signal-regulated kinase (ERK)in central nucleus of amygdala (CeA)in the mechanism of fentanyl-induced hyperalgesia (OIH)in rats. Methods Step 1:12 healthy male Sprague-Dawley rats,weighing 60-100 g,were randomly divided into OIH and Control group.The mechanical paw withdrawal threshold (PWT)and the thermal paw withdrawal latency (PWL)were tested at pre-and post-OIH induction.Then the level of p-ERK in the CeA was analyzed by Western blotting.Step 2:After successful induction of OIH and catheterization in CeA,another 30 SD male rats were randomly divided into 5 groups (n = 6 each):Group OIH;Group OIH+U0124;Group OIH+U0126(0.1 5 nmol);Group OIH+U0126(0.45 nmol)and Group OIH+U0126 (1.5 nmol),then 0.3 μl of DMSO,U0124 (1.5 nmol),U0126 (0.1 5 nmol,0.45 nmol,1.5 nmol)was given through the catheter separately.PWT and PWL were tested before cathe-terization,at pre-OIH induction,post-OIH induction and 0.5 h after CeA drug administration.After the last test of pain threshold,the rats were sacrificed and CeA tissues were sampled for analyzing the expression of p-ERK by western blot.Results In step 1 compared with control group,PWT and PWL of OIH group were sharply decreased post-OIH induction (P <0.05),concomitant increase of the expression of p-ERK in CeA in OIH group was also observed.In step 2,both PWT and PWL were sharply decreased post-OIH induction (P <0.05).Intra-CeA U0126 injection,but not U0124, reversed both behavioral hyperalgesia and molecular activation of ERK in CeA in a dose-dependent manner (P <0.05).Conclusion ERK plays a pivotal role in the maintenance of fentanyl-induced hy-peralgesia.Targeting inhibition of ERK activation in CeA can alleviate fentanyl-induced hyperalgesia.
