Objective: To explore the effects of Polygonatum odoratum on body based on metabonomics. Methods: The ultra performance liquid chromatography coupled with mass spectrometry (UPLC-MS) and principle component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were used to evaluate the changes of endogenous substances in rats after intragastric administration of Polygonatum odoratum. Results: Significant differences between the control group and administration group were observed in PCA and OPLS-DA model. Five potential biomarkers between control group and administration group were identified. The relative content of Alpha-Tocotrienol, PC(14:1(9Z)/14:1(9Z)), Stearic acid, Theasapogenol A, Docosahexaenoic acid increased. Conclusion: The biomarkers had many beneficial activities, so the Mongolian medicine Polygonatum odoratum had the function of health care.

S801 leukemic cell line established by our department was used as cells for interferon (IFN) induction and stimulating induction. S801 cell culture of concentration of 5-8x10~6 cells/ml was used for IFN induction and IFN titer of 3.55 Lg IU/ml was obtained by classical procedure. The IFN titer obtained S801 cell cultures after pretreatment with Ciwujia eleutherosides B. D and E or polysaccharide (PES) combined with priming procedure,then using Sendai Virus as an inducer was 10-20 times higher than that in cultures without any pretreatment. These Chinese medical herbs may be the ideal IFN helpinducers. This cell line may be applied for IFN production.

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

Objective:To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods:Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence.Both groups received the same basic treatment.In the EA group,48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy;47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydroch｜oride at Jiaji (EX-B 2) points.The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups.Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results:After treatment,the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group,respectively (both P＜0.05);the content of IL-1β,ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P＜0.05).Conclusion:The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly,and is superior to EA at Jiaji (EX-B 2) points alone.

Objective To evaluate the precision of GFR using Gates method and compared with the results from renal pathological changes. Methods Twenty-seven patients whose 99Tcm-DTPA renograms had no obvious uptake phase were enrolled in Group A, and 27 patients whose 99Tcm-DTPA renograms had obvious uptake phase were enrolled in Group B. The measurement of GFR by Gates method was compared to the creatinine clearance measured and predicted by Cockroft-Gault (C-G), modification of diet in renal disease (MDRD) and SCr level. Renal pathological changes in two groups were compared using Pearson correlation and t test analysis. Results In Group A, GFR determined by Gates method did not show correlation with that estimated by C-G or 1/SCr (r = 0. 357,0. 376, both P ＞0.05), but was significantly correlated with GFR estimated by MDRD(r = 0. 440, P ＜ 0.05). In Group B, GFR determined by Gates method showed significantly correlation among GFR estimated by MDRD, C-G, and 1/SCr (r =0. 471, 0. 527,0. 452, all P ＜ 0.05). Renal tubulointerstitial damage score in Group A was higher than that in Group B (7.15±2.32, 3.70±3.06, t=4.66, P ＜0.001). Conclusions GFR determined by Gates method is less precise when 99Tcm-DTPA renogram has no obvious uptake phase than that when 99Tcm-DTPA renogram has obvious uptake phase. Renal tubulointerstitial damage is a strong indicator of no obvious uptake phase in 99Tcm-DTPA renogram.

3-8 years old group(group C2) with 50 cases] were detected.A gonadotropin releasing hormone analogue(GnRHa) stimulation test was performed in 140 girls with IPT.The 140 girls were divided into 3 groups:IPT group,CPP group,and peripheral precocious puberty group(PPP group).Kruskal-Wallis and Mann-Whitneg tests were performed on the data between every groups.Results For basal LH levels,there were significant diffe-rences between IPT1 group and group C1,among IPT2 group,CPP group and group C2(Pa0.05).For peak LH/FSH ratios,there was significant difference between IPT2 group and CPP group(P

OBJECTIVETo study the clinical features of neonatal diabetes mellitus (NDM).

METHODThirteen cases with NDM were seen in our department between Jul. 2004 and Sept. 2009. Their clinical features were reviewed retrospectively.

RESULTSThe average birth weight of the 13 cases was 2.30 kg. The median age at diagnosis was 2 months. The mean blood glucose at diagnosis was 22.2 mmol/L. Symptoms in 9 of 13 cases were exacerbated by infection and only 5 had typical symptoms of diabetes mellitus including polydipsia, polyuria, polyphagia and body weight loss. The common clinical findings included athrepsia, diuresis, and moderate dehydration. Ketoacidosis attacked 3 cases and 3 children had hypertriglyceridemia, meanwhile, 2 children had complications of blood clotting dysfunction and congenital cardiopathy, respectively. Autoantibody to insulin (IAA) was tested in 11 cases, all but one case was negative. Glycosylated hemoglobin was increased in 6 cases. Insulin treatment was started in all the 13 cases. The initial dose was 0.56-1.00 U/(kg × d), and the maximal dose was 1.35 U/(kg × d) depending on the variety of blood glucose. Blood glucose decreased significantly within 24 hours. Unfortunately, 1 case developed progressive blood glucose decline and recurrent hypoglycemia. Symptoms of the 3 cases who developed DKA were relieved 48 hours later, and their blood glucose was well under control. Among the 8 cases followed up, 4 had TNDM and 2 had PNDM. Unfortunately, 1 case died at the age of 3 months because insulin injection was stopped by the parents.

CONCLUSIONEarly diagnosis and prompt management may lead to favorable prognosis. Blood glucose monitoring is a valuable method to avoid misdiagnosis and NDM should be differentiated from stress hyperglycemia, iatrogenic, or other causes of hyperglycemia.

OBJECTIVETo observe the effects of color silk cocoon extraction-sericine on transforming growth factor-beta1 (TGF-beta1) and Smad3 protein expression in kidney of diabetic nephropathy (DN) rats.

METHODS60 male SD rats were randomly divided into 5 groups (n = 12): normal control group, DN model group, sericine treatment group, metformin group and sericine prevention group. The rats in model group, sericine treatment group, metformin group and sericine prevention group were all established DN rats model by intraperitoneally injected streptozotocin (STZ). Blood glucose > or = 16.7 mmol/L was taken as standard to judge if the rats model were successfully established. After the rats model were successfully established, the rats in sericine treatment group were lavaged with sericine (2.4 g/(kg x d), 35 d). The rats in metformin group were lavaged with metformin (55.33 mg/(kg x d), 35 d). The rats in sericine prevention group were lavaged with the same dose sericine for 35 d before injecting STZ. The blood glucose and kidney weight/body weight of rats in each group were respectively detected. Immunohistochemical staining was used to observe the expression of TGF-beta1 and Western blot to detect the expression of Smad3 in kidney.

RESULTSCompared with normal control rats: the blood glucose, kidney weight/body weight, TGF-beta1 and Smad3 expression in kidney of rats in model group increased obviously (P < 0.01). The blood glucose, TGF-beta1 and Smad3 expression in kidney of rats in sericin treatment group, sericin prevention group and metformin group were significantly lower than that of model group (P < 0.01). Moreover, there were no obvious differences between sericin treatment group, sericin prevention group and metformin group (P > 0.05). The kidney weight/body weight of rats in sericin treatment group, sericin prevention group and metformin group were significantly lower than that of model group (P < 0.01). Moreover, the kidney weight/body weight of rats in sericin treatment group and sericin prevention group were obviously lower than that of metformin group (P < 0.05).

CONCLUSIONSericin can inhibit activation of TGF-beta1/Smad3 signal pathway in kidney of DN rats, lighten glomerulosclerosis and renal interstitial fibrosis, so has protective and preventive effects on kidney injury of DN rats. Moreover, the therapeutical and preventive effects of sericin on DN are similar with metformin.
