Objective To investigate the relationship between serum growth hormone, C-peptide, blood lipids levels, blood glu-cose, hypertension and type 2 diabetes nephropathy. Methods 82 type 2 diabetes (including 40 without nephropathy and 42 with nephropa-thy) and 39 healthy objects were enrolled. BG,GH,C-P,HbAlc,TC,TG,LDL-C and HDL-C were detected. Results The results showed that the values of blood glucose in each time-phase and HbAlc in both type 2 diabetes groups were significantly higher than that in healthy objects. In type 2 diabetes nephropathy group, the serum levels HbAlc, FGH, TC, TG, LDL-C, systolic blood pressure and diastolic blood pressure were significantly higher than that without nephropathy and those healthy objects(P<0.01). C-P (Oh)and C-P (2h)in type 2 di-abetes nephropathy group was significantly lower than that without nephropathy and those healthy objects(P<0.01). In groups patients of type 2 diabetes nephropathy, the disease duration had significantly longer than patients without nephropathy (P<0.01). The results of cor-related analysis with Pearson showed that HbAlc was significantly positive correlated with FGH(r=0.912, P<0.01), HbAlc was signifi-cantly negatively correlated with C-P(0h)(r=-0.803, P<0.01)and HbAlc was significantly negatively correlated with C-P(2h)(r=-0.771, P<0.01). FGH was significantly positive correlated with TC (r=0.413, P<0.05). Conclusion These results suggested that type 2 diabetes nephropathy has persistent elevated levels of blood glucose and disorder of lipid metabolism. The elevated levels of FGH, hy-pertension and islet B cell secretion function deficiency are important risk factors for type 2 diabetes nephropathy.

Objective: To analyse the antinociceptive effect of red nucleus (RN) and its role in the antinociceptive effect of muscle spindle afferents. Methods: The single units of RN or wide dynamic range (WDR) neuron in the spinal cord dorsal horn were extracelluarly recorded. The effects of RN stimulation on nociceptive responses (C-fibers-evoked responses, C-responses) of WDR neurons were observed. The influence of muscle spindle afferents elicited by intravenous administration of succinylcholine (Sch) on the spontaneous discharge of RN neurons and on C-responses of WDR neurons were observed. The effect of muscle spindle afferents on C-responses of WDR neurons after unilateral lesions of RN was also observed. Results: Electrical stimulation of the RN produced a significantly inhibitory effect on the nociceptive responses of WDR neurons. RN neurons were excited by muscle spindle afferents. Muscle spindle afferents significantly inhibited C-response of WDR neurons and this inhibitory effect was reduced by lesions of RN. Conclusion: RN neurons have a significant antinociceptive effect and might be involved in the antinociceptive effects elicited by muscle spindle afferents.

OBJECTIVE:To establish a HPLC method for the determination of 5-fluorouracil in human plasma METHODS:The plasma samples were extracted with ethyl acetate-isopropanol(85∶15,V/V)following precipitation of plasma proteins with ammonium sulfate The solvent was evaporated to dryness under a stream of nitrogen The dry extract was dissolved in mobile phase and then injected into the Diamonsil C18 column(150mm?4 6mm,5?m)and 0 01mol/L KH2 PO4(pH5 5) was taken as mobile phase The flow rate was 1 5ml/min,UV detection wavelength was 267nm The internal standard was 5-bromouracil RESULTS:The minimal detectable drug concentration in plasma was 0 025?g/ml The calibration curve was linear over a range from 0 3?g/ml to 10?g/ml The intra-day RSD≤5 0%(n=5) and the inter-day RSD≤11 5%(n=5) CONCLUSION:The method can be used for studying the pharmacokinetics and bioavailability of 5-fluorouracil

OBJECTIVE:To establish the quality standard for Prostatitis capsules. METHODS:TLC method was performed to qualitatively identify Pseudostellaria heterophylla,Acortw tatarinowii,Sargentodoxa cuneata,Rubia cordifolia and Vaccaria segeta-lis in the preparation. HPLC method was adopted to determine the content of leonurine in the preparation. The determination was performed on Agilent Eclipse XDB-C18 column with mobile phase consisted of methanol-0.025 mol/L potassium dihydrogen phos-phate(pH adjusted to 2.5)(24 : 76,V/V)with phosphoric acidat the flow rate of 1.0 mL/min. The detection wavelength was set at 277 nm,and column temperature was 30 ℃. The sample size was 10 μL. RESULTS:The TLC spots of P. heterophylla,A. tatari-nowii,S. cuneate,R. cordifolia,and V. segetalis were clear and well-separated without interference from negative control. The lin-ear range of leonurine were 4.05-81.00 μg/mL(r=0.9999). RSDs of precision,stability and reproducibility tests were all lower than 2.0%. The recovery was 98.47%-103.83%(RSD=2.04%,n=9). CONCLUSIONS:Established standard can be used for quali-ty control of Prostatitis capsules.

Objective To compare the demographic and anthropometric characteristics of IFH,IPH and CH in a Chinese newly diagnosed diabetes population and to evaluate the metabolic profiles of insulin secretion and insulin sensitivity associated with subcategories of newly diagnosed type 2 diabetes.Methods From Mar.2005 to June 2002,in Qingdao 335 patients with newly diagnosed diabetes were classified into three groups:IFH(n=67),IPH(n=92),and CH(n=176).Meanwhile,411(191males)subjects with age-sex matched were selected as control group. Homeostasis model assessment(HOMA-IR)and LIGUANGWEI index(IAI)were applied to assess the status of insulin resistance.Homeostasis model assessment(HOMA-B)and I_0/G_0 were applied to assess the basic function of islet B cell,and I_ 120 /G_ 120 was applied to assess the postload function of islet B cell. Results HOMA-IR increased and IAI decreased significantly in CH group than in IFH and IPH group(P

Objective This study was designed to evaluate the biomechanical properties in tendons across the joints when Palmar or dorsal stitches were used. Methods Twenty porcine tendons were transected and then repaired in zone Ⅱand divided into two groups,using modified Kessler by placing the stitches in volar or dorsal part of tendons.The repaired tendons were placed on a joint model with flexion of 60?. An instron tensile testing machine was used to investigate 2 mm gap formation force and ultimate tensile strength. Results 2 mm gap formation force and ultimate tensile strength were both higher when dorsal placement of stitches was used. Conclusions Dorsal placement of stitches was recommended for repairing the tendons across the joints because it can offer greater tensile strength.

Objectire To investigate female urogenital fistula on the cause,diagnosis and treatment.Methods Thirty nine cases of patients were diagnosed ashaving genitourinary fistula by cystoscopy,intravenous urography,and blue methvlenelest.In 51%of cases were uretero-vaginal fistulas(20/39),one of them were trated byrenal ostomy.17 cases by early emergency ureteroneocystomy,2 cases by ureteralcatheter.In two complex patients with vesico.uretero-vaginal fistula(2/39),the repairwas associated with badder approach vesicovaginal fistula and early emergencyureteroneocystomy.In 44%of cases with vesicovaginal fistula(17/39)were trated bybladder approach after 3～27 months.Results 36 cases of patients were cured after surgery in one time,2 cases of ureteral intubation,1 case of nephrostomy and nephrectomy later with renal infection,1 case of uroclepsia complication.Conclusion Surgical repair of genitourinary fistula will have high rates of success if performed in proper time and appropriate approaches on the basis of patientinf eirmation and urinary fistula pathological type by experienced hands.

Objective To study the relationship between extracranial carotid arerial stenosis and OCSP typing of acute cerebral infarction. Methods 188 patients with acute cerebral infarction were classified into TACI, PACI, POCI and LACI subtype by OCSP criteria. The lumen diameter, intima-media thickness, plaque, severity of ar-terystenosis of extraeranial carotid arteries in patients with acute cerebral infarction was studied by using HDI-5000 color Doppler ultrasound. Resnlts The prevalence of extracranial carotid arterial stenosis was higher in patients with TACI, POCI subtype than in patients with LACI subtype (X2 = 4.87, P < 0.05 ; X2 = 4.58, P < 0.05). The severity of extracranial carotid arterial stenosis were more prominent in patients with TACI,POCI subtype than in patients with LACI subtype(X2 =7.59,P <0.01 ;X2 =6. 96,P <0.01). Conclusion Extraeranial carotid arterial stenosis and its severity are related to TACI, POCI subtype of OCSP criteria in patients with acute cerebral infarction.
