ObjectiveTo explore the characteristics of traditional Chinese medicine (TCM) syndrome differentiation in chronic complications of type 2 diabetes mellitus (DM).Methods124 patients with chronic complications of type 2 DM were scored by 5 grades according as the severities of their symptoms. There were 5 kinds of patterns such as deficiency of Qi, deficiency of Yin, deficiency of Yang, blood stasis and retention of phlegm and fluid by which the TCM syndrome differentiation was generalized.ResultsThe sequence of TCM patterns was deficiency of Yin, blood stasis, deficiency of Qi, deficiency of Yang and retention of phlegm and fluid, and the syndrome of the two formers were greater than 50%. The proportion of unity of deficient and excessive pattern was 80.5%. Three larger syndrome types were deficiency of both Yin and Yang combined with blood stasis (17.7%), Qi-Yin deficiency with blood stasis ( 16.9 %) and Yin deficiency with blood stasis (16.9%). There was a statistically significant difference in TCM syndromes which were divided into different groups by course of diseases (P<0.05). At onset of DM, the typical symptoms were less observed in the group whose course of disease was less than 5 years, and only 39.1% of patients had the typical symptoms. But at the same time, the prevalences of hypertension and hyperlipidemia were higher in this group than in the others, respectively 63.0% and 87.0%.ConclusionThe primary syndrome is unity of deficient and excessive pattern in chronic complications of type 2 DM and deficiency of Qi and blood stasis are the commonest patterns in course of DM.

AIM: To investigate the effects and quantitative relations of co-administering probenecid OF different dosages on pharmacokinetics of cefaclor in rabbits and approach the possible mechanisms involved as well. METHODS: Monitor plasma and urine cefaclor concentrations. 24 male rabbits were randomly divided into 4 groups by Cefaclor 50 mg·kg-1,Cefaclor50 mg·kg-1+Probenecid 100 mg·kg-1,Cefaclor 50 mg·kg-1+Probenecid 250 mg·kg-1 and Cefaclor 50 mg·kg-1+Probenecid 625 mg·kg-1.Blood and urine samples were collected according to the regular time schedule after intragastric administration. The concentration of cefaclor in blood and urine were determined by HPLC. Pharmacokinetic parameters were calculated by DAS (Drug and Statistical) software. Measur plasma protein-binding rate of cefaclor. The experimental groups and drug dosage were same as described above. The blood sample was drawn at 1 hour after administration,and the protein-binding rate of cefaclor was determined by equilibrium dialysis. RESULTS: Within the dosages of probenecid ranged from 0-250 mg·kg-1,T1/2ka,Tmax,Cmax and AUC of cefaclor increased in accordance with increasing dosage of co-administering probenecid while CL/F and Vd/F were decreased(P＜0.01); However,when the dosage of co-administering probenecid was 625 mg·kg-1,Cmax of cefaclor strikingly decreased(P＜0.01),while AUC and CL/F maintained at the levels of those with probenecid250 mg·kg-1.In this experiment, urinary excretive peak time of cefaclor in its prototype pos tponed gradually,biological half life prolonged and urinary excretive accumulation percentage decreased obviously(P＜0.01).To the dosages of probenecid ranging from 0-250 mg·kg-1,protein-binding rate of cefaclor decreased notably(P＜0.01)going with increasing dosages of co-administration probenecid; While the dosage of co-administration probenecid reached 625 mg·kg-1,the protein-binding rate of cefaclor corresponded to that of cefaclor 50 mg·kg-1 without probenecid (P＜0.01).CONCLUSION: Co-administering probenecid can strikingly change pharmacokinetics of cefaclor and the influential degree of pharmacokinetics parameters is dependent on dosages of probenecid used in the experiment. Biological half life prolongs and urinary excretive accumulation percentage of cefaclor decreases obviously.

Objective To discuss the frequency distribution of single nucleotide polymorphisms (SNP) of four asthma-related gene loci in asthmatic children of Henan,and to investigate its association with genetic susceptibility to childhood asthma and some clinical phenotypes of asthma Methods Fluorogenic quantitative PCR and sequencing technique were employed to detect the frequency distributions of the SNP of the four asthma-related gene loci in 135 asthmatic children and 98 healthy controls.Results The genotype DD of angiotensin-converting enzyme (ACE)had a significantly higher frequency in the asthmatic children than in the healthy controls (x2 =26.475,P ＜ 0.01),and the frequency of D allele was also significantly higher in the asthmatic children than in the healthy controls (x2 =24.242,P ＜0.01).The genotype AG of Adrenaline receptor beta 2 subtypes (ADRB2) had a significantly higher frequency in the asthmatic children than in the healthy controls (x2 =22.505,P ＜0.01),and the frequency of allele was also significantly higher in the asthmatic children than in the healthy controls (x2 =6.759,P ＜ 0.01).Conclusions Genotype DD of ACE and genotype AG of ADRB2 are related to genetic susceptibility to childhood asthma and may be the risk factor for childhood asthma of Henan.Another two asthma genes involved in this study are not be able to repeat.

Objective To observe the effect of irbesartan on the expression of angiopoietinlike protein 2 (ANGPTL2) in the diabetic rats kidney and explore the underlying mechanism.Methods A total of sixty male SD rats were divided into normal control group (NC group,n=15) and experimental group (n=45) randomly.The experimental group was fed with high sugar-fat diet and given a low dose streptozocin (STZ 30 mg/kg)to establish type 2 diabetic model.Rats successfully induced diabetes were randomly divided into 2 groups:diabetes group (DM) and irbesartan group (DI).Weight,blood pressure,blood glucose,serum creatinine (Scr),blood urea nitrogen(BUN),24 hour urinary albumin(UAL) and renal histomorphology were observed after drug intervention at the 4th,8th and 12thweeks.The expression of ANGPTL2 in renal tissue were detected by immunohistochemistry,real-time PCR and Western blotting.Results The levels of Scr,BUN,TG,TC and UAL in group DM were higher than in group NC at the 4th,8th and 12th week (all P ＜ 0.05).Compared with that in group DM,above indexes were lower in group DI at the 4th,8th and 12th week (all P ＜ 0.05).The pathological changes of the kidney in group DM were more serious than that in group DI.The expression of ANGPTL2 in group DM was much higher than that in group NC at the 4th,8th and 12th week (all P ＜0.05),and irbesartan treatment inhibited the up-regulation of ANGPTL2 in group DI(all P ＜ 0.05).Conclusion The expression of ANGPTL2 increases in T2DM rats kidney tissue with time and irbesartan can inhibit the up-regulation of ANGPTL2 in T2DM rats.

Objective:The current study investigated the effects of nesfatin-1 in the hypothalamic paraventricular nucleus (PVN) on gastric motility and the regulation of the lateral hypothalamic area (LHA).Methods:The projection of nerve ?ber and expression of nesfatin-1 were observed by retrograde tracing and fluo-immunohistochemistry staining;The nuclei microinjection and nuclei electrical stimulation,extracellular discharges of single unit neuron were used to observe the effects of nesfatin-1 on the GD neurons;Gastric motility recording in vivo were used to monitor the effects of nesfatin-1 on the amplitude of constriction and frequency of gastric motility in conscious rats.Results:Nesfatin-1 inhibited the majority of the GD-E neurons(1.97± 0.12 Hz vs.1.15± 0.07 Hz) and excited GD-I neurons (1.74± 0.10 Hz vs.3.04± 0.18 Hz) in the PVN,which were weakened by oxytocin receptor antagonist H4928 (GD-E:1.38± 0.08 Hz,P＜0.05 vs.nesfatin-1;GD-I:2.49± 0.15 Hz,P＜0.05 vs.nesfatin-1).Gastric motility experiments showed that administration ofnesfatin-1 in the PVN decreased gastric motility.Retrograde tracing and immunofluorescent staining showed that nucleobindin-2/nesfatin-1 and fluorogold double-labeled neurons were observed in the LHA.Electrical LHA stimulation excited the firing rate of GD-responsive neurons (GD-E:2.06± 0.12 Hz vs.4.23± 0.21 Hz,GD-I:1.61± 0.09 Hz vs.4.83± 0.25 Hz) in the PVN.Pre-administration of an antinucleobindin-2/nesfatin-1 antibody in the PVN strengthened gastric motility,decreased GD-E neurons (1.74± 0.10 Hz vs.3.04± 0.18 Hz) and excited the discharging of the GD-I neurons(4.15± 0.18 Hz vs.4.83± 0.25) induced by electrical stimulation of the LHA.Conclusion:Nesfatin-1 in the PVN could serve as an inhibitory factor to inhibit gastric motility,which might be regulated by the LHA.

Objective To evaluate the relationship of high mobility group box 1 (HMGB1) and TLR4 with airway inflammation and the role of vitamin D.Methods Totally 24 BALB/c mice were randomly divided into control group,asthma group,and 1,25-(OH)2D3 group,each having 8 mice.The pathological changes in lung tissue of the mice were observed by hematoxylin-eosin (HE) staining,bronchial wall thickness was measured with computer pathological image analysis system software.The expressions of HMGB1 and TLR4 in lung tissue were detected by immunohistochemical method.Bronchoalveolar lavage fluid (BALF) was collected for cytological examination;the contents of HMGB1,TLR4,IL-4 and IFN-γ in BALF and the peripheral blood were detected by enzyme-linked immunosorbent assay (ELISA).Results The expressions of HMGB1 and TLR4 in lung tissue were stronger in asthma group,but weaker in intervention group.The total number of leukocytes as well as the percentages of eosinophils,neutrophils and lymphocytes increased significantly in BALF in asthma group,but significantly decreased in intervention group (all P ＜ 0.05).The ratio of monocyte/macrophage significantly decreased in asthma group,but increased significantly in intervention group (P＜0.05).The contents of HMGB1,TLR4 and IL-4 in BALF and the peripheral blood were significantly higher in asthma group than in control and intervention groups,whereas IFN-γ level was significantly lower than that in control and intervention groups (all P＜0.05).HMGB1 and TLR4 contents had a positive correlation with the total number of cells and IL-4 concentration in BALF,respectively (r1=0.796,0.730;r2=0.695,0.648;all P＜0.05).Conclusion HMGB1 and TLR4 were associated with airway inflammation and immune disorders.An appropriate amount of 1,25-(OH)2D3 can relieve airway inflammation,which may be associated with regulating Th1/Th2 cells balance.
