Effects of the extracts from Lapemis hardwickii on RBCs count and Hb content were studied in the both of mice model of which was made by acetylphenyhydrozine (APH) for hemolytic anemia and of by Chinese rubarb for Xue Xu (debility due to blood deficiency). The results showed that counts of red blood cell (RBC) and content of hemoglobin (Hb) of experimental group in hemolytic anemia model mice were higher significatly than that of control gooup in hemoly ticanemia mice. The content of Hb was increased in Xue Xu mice model,but no marked effect on the counts of RBCs. The study showed that the extract could have a better profective effect on red blood cells of hemolytic anemia mice.

Objective:To explore the mechanism of islet cell apoptosis caused by glucose at different concentrations.Methods:The islet cells of SD adult rats were prepared by collagenase digestion,purified by Fcoll400 and cultured in RPMI1640.Different concentrations of glucose or mannitol were added into the monolayer of islet cells.The medium insulin concentration was measured by RIA.The apoptosis rate was measured by the flow cytometry and the bax and bcl-2 expressions were detected by immunoblot.Results:①With glucose concentration raised from 11.1 mmol/L to 22.2 mmol/L,the insulin concentration began to raise and reached the peak,then it began to decline.②With glucose at 11.1 mmol/L and 22.2 mmol/L,the apoptosis rate was the highest,while at 5.5 mmol/L,there was no significant difference compared with the controls. For the groups of mannitol-infused,there was no differences of bax or bcl-2 expressions and no difference of the apoptosis rate comparing with the controls.③With glucose infused,the bcl-2 expressions in 11.1 mmol/L and 22.2 mmol/L groups were negative,bax expression was positive;the bax and bcl-2 expressions were negative in the group of 33.3 mmol/L;the bax and bcl-2 expressions in the 5.5 mmol/L group showed no difference compared with the controls.Conclusion:Higher levels of glucose at 11.1mmol/L and 22.2 mmol/L lead to the release of more insulin and the raise of apoptosis rate.But with glucose concentration at 33.3 mmol/L,the release of insulin decreased and the apoptosis rate declined.Hyperosmolality could not cause the apoptosis of the islet cell.

OBJECTIVETo compare the clinical effective differences between acupuncture-moxibustion and Chinese herbs for functional dyspepsia with emotional disorder.

METHODSEighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, based on the basic treatment Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Danzhong (CV 17), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18), Geshu (BL 17) and Danshu (BL 19) were selected once every day or every other day. The treatment was given 14 times. In the control group, based on the basic treatment individual therapy of Chinese herbs according to syndrome differentiation was applied,one dose a day. Patients were treated for 4 weeks in the two groups. The scores of self-rating depression scale (SDS), the main symptoms and satisfied degree by self-rating for treatment were observed before and after 4-week treatment in the two groups. Also, the rate and the average time of return visit were compared in 6 months after treatment. Results After treatment, the SDS scores and the main symptoms scores were all improved compared with those before treatment in the two groups (all P< 0. 05). After 4-week treatment, the improvement of the SDS score in the observation group was better than that in the control group (48. 9±8. 5 vs 53. 1±8. 0, P<0. 05). After 1-week treatment and 4-week treatment, the improvements of the main symptoms in the observation group were superior to those in the control group (2. 7 ± 1. 0 vs 3. 3±0. 9, 1. 5±0. 9 vs 2. 3±1. 1, both P<0. 05), and the satisfied degree scores by self-rating were better than those in the control group (3. 0±1. 1 vs 3. 8±1. 3, 2. 0±1. 4 vs 2. 9±1. 5, both P<0. 05). In 6 months after treatment,the return visit rate in the observation group was 42. 5% (17/40), and it was lower than 70. 0% (28/40) in the control group (P<0. 05). The average time of return visit in the observation group was less than that in the control group (1. 0±0.8 vs 1. 9±0. 7, P<0. 05).

CONCLUSIONThe effect of acupuncture-moxibustion or functional dyspepsia with emotional disorder is better than that of Chinese medicine.

Objective To observe the effects of aminoguanidine and Vitamin C on lipid of streptozotocin-induced didbetic rats.Methods Diabetic nephropathy rats were induced by intraperitoneal injection of streptozotocin.Fifty Sprague-Dawley(SD) rats were randomly divided into normal control group,model group,Vitamin C group,aminoguanidine group and Vitamin C associated with aminoguanidine group.All the rats were treated for 16 weeks.During and after the treatment,the general state of the rats was observed and the levels of blood sugar,triglyceride,total cholesterol,low density lipoprotein,high density lipoprotein,glycosylated hemoglobin,and glycated low density lipoprotein in different groups were detected.Results The rats in the four groups suffered diabetes mellitus and renal function lesion.Aminoguanidine and Vitamin C could improve the general state of the rats,but had no effect on the blood sugar.Vitamin C could decrease the levels of triglyceride,serum cholesterol,low density lipoprotein,glycosylated hemoglobin,and glycated low density lipoprotein,and increase the level of high density lipoprotein.There was a synergistic effect with the combination of the two drugs. Conclusion Aminoguanidine and Vitamin C have no effect in the decrease of blood sugar level but have a certain effect on regulating blood lipid.There is a synergistic effect with the combination of the two drugs.

Objective To explore the effect of ACE-inhibitor perindopril on the expression of scavenger receptor A (SR-A) gene in the kidney of diabetic rats.Methods Diabetes were induced in male Sprague-Dawley rats by peritoneal injection with streptozotocin (60mg/kg).The rats were then random di vided into normal control group, diabetes group and ACEI treatment group [4mg/(kg·d) for 24 weeks].Blood glucose concentration and 24h urinary albumin excretion were determined.The renal morphological change was observed.Immunohistochemistry was used to analyze CD68 positive macrophages,and the Mrna of SR-A in renal tissue was detected by quantitative real-time PCR.Results Compared with normal control group,blood glucose concentration,24h urinary albumin excretion and the number of CD68 positive macrophages were significantly increased [(5.3 ± 0.6) mmol/L vs (26.7 ± 3.3) mmol/L;(2.7 ± 1.3) mg/24h vs (26.7 ± 1.8)mg/24h;(0.77 ±0.24)/gcs vs (2.55 ±0.46)/gcs;(6.13 ±0.50)/HPF vs (11.9 ±2.12)/HPF;P ＜0.05],and the expression of SR-A Mrna were significantly up-regulated in diabetes group [ (5.6 ± 1.2 vs 1.5 ±0.2),P ＜0.05].After intervention with ACE-inhibitor,the up-regulations of the above mentioned parameters,except blood glucose concentration,were all significantly inhibited [ (3.6 ±1.4)mg/24h;(1.03±0.37)/gcs;(8.28±1.19)/HPF;3.4±0.7;P ＜0.05].Conclusion ACE-inhibitor might have renoprotective effects of diabetic nephropathy,it probably was associated with inhibiting the expression of SR-A gene.

Objective To analyze the metabolic profile in serum between normal and orthotopic xenograft nude mice burdened with three human pancreatic cancer cell lines,which were differentiated differently.Methods Human pancreatic cancer lines SW1990,BxPC-3 and Panc-1 were subcutaneously injected into the nude mice,respectively.When the tumor volume reached 1.0 cm3,the nude mice were euthanized and the tumor tissues were removed and implanted to the pancreas to establish the orthotopic xenograft mice model.The serum from three orthotopic xenograft tumor nude mice and the normal controls were collected and then analyzed by 1H nuclear magnetic resonance spectroscopy.Results The three orthotopic xenograft nude mice models were successfully established.In SW1990,BxPC-3 and Panc-1 group,the orthotopic xenograft tumor formation rate was 79％ (11/14),93％ (13/14) and 86％ (12/14),while the mortality was 7％ (1/14),0 and 7％ (1/14),respectively.Compared with control group,the content of metabolites in the serum of orthotopic xenograft tumor nude mice was increased including creatine,alanine,glutamine,1-methylhistidine,isoleucine,lactate,phenylalanine,tryptophan and valine,but the glycerolphosphocholine (GPC) and glucose levels were reduced.As the tumors progressed to be more malignant,the content of valine and isoleucine tended to increase.Conclusions The establishment of the orthotopic implantation tumor nude mice model was stable and reliable with high tumor formation rate.Obvious metabolic differences of glucose,lipid and amino acids were observed between normal and human pancreatic cancer tumor burdening nude mice models.The common metabolic features identified in all three nude mice models burdened with human pancreatic cancer could be used as the potential markers for diagnosing human pancreatic cancer.

Objective To investigate the clinical value of serum metabonomic profile of pancreatic cancer using nuclear magnetic resonance (NMR)-based metabonomics.Methods The retrospective case-control study was adopted.The clinical data of 23 patients with pancreatic cancer (PC group) and 16 healthy volunteers (control group) who were admitted to the Fujian Medical University Union Hospital between December 2013 and December 2014 were collected.The serum of the 2 groups was measured by 1H NMR spectroscopy.Multivariate statistical analyses were performed to identify the characteristic metabolites in the 2 groups,including principal component analysis (PCA),partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA).Observation indicators included:(1) multivariate statistical analysis of serum metabonomic profile,results of PCA,PLS-DA and OPLS-DA,(2) screening of metabolites.Measurement data with normal distribution were presented as x ± s.The comparison between groups was evaluated with the t test.The count data were analyzed using the chi-square test.Results (1) The multivariate statistical analysis of serum metabonomic profile:results of PCA showed that expression rates of principal component 1 (PC1) and principal component 2 (PC2) to original data were 54.9％ and 23.5％,with both cumulative contribution rate of 78.4％.Results of PLS-DA showed that the separative trend between PC group and control group was appeared,and variance of X and Y matrixes and predictive value were 0.254,0.816 and 0.385.Results of OPLS-DA showed that the differences of samples between the 2 groups were further increased,and differential metabolites were screened according to the distinction of scores between the 2 groups,value of R2X,R2Y and Q2 was 0.254,0.816 and 0.433.(2) Screening of metabolites:35 serum metabolites were detected in the 2 groups.Compared with the control group,levels of 3-hydroxybuyarate,citrate,formate,glutamate,isoleucine,methionine and phenylalanine in the PC group were elevated (r =0.524,0.511,0.656,0.566,0.503,0.498,0.648,P ＜0.05),and levels of 3-methylhistidine,alanine,glutamine,LDL and VLDL in the PC group were decreased (r =-0.607,-0.508,-0.560,-0.568,-0.559,P ＜ 0.05).Conclusions Compared with healthy controls,several amino acids,citrate and lipoproteins demonstrate the metabolic differences in the serum of patients with pancreatic cancer.NMR based metabonomic profile technology can distinguish the difference of serum metabolites between patients with pancreatic cancer and healthy controls.NMR based metabonomic technology may be a promising method for the diagnosis of pancreatic cancer.

Objective To illustrate if the racial coefficient (Rc) be biased by different reference GFR (rGFR) distribution among studies. Methods 1405 white and 321 African American participants in MDRD study and 684 chronic kidney disease(CKD)patients in Chinese eGFR Investigation Study were included.Firstly.the unweighted datasets of white and Chinese were stacked together.rGFR,age and plasma creatinine (Pcr) were log transformed.Linear regression model was constructed using log transformed rGFR as dependent,gender,race and log transformed Pcr and age as independent.Unweighted RC (uRC) for Chinese was calculated.Then.the Chinese CKD distribution of rGFR was weighted to be the same as that in White American.and weighted RC (wRC)for Chinese was calculated.The cases of White.and African-American were stacked together.The cases of African-American were weighted to make the rGFR distribution the same as that in White-American and Chinese population respectively,and RCs for African-American were calculated. Resuits The uRC for Chinese was 1.197(1.180-1.211)and the wRC was 1.130 (1.117-1.143).The two RCs did not overlap with each other.The RCs for African-American were 1.205(1.19-1.219)and 1.233(1.219-1.247)respectively. Conclusions The RCs were influenced by the difference of rGFR distribution.To find out the real RC.an intemational collaborative study iS needed,with the same rGFR measure method.strict control of Pcr measurement,and the same rGFR distribution.

Objective To investigate the antimicrobial resistance of Streptococcus pneumoniae strains isolated from multiple medical institutions across Hebei Province in 2015.Methods The bacterial data were collected from 53 member hospitals of Hebei Antimicrobial Resistance Investigation Net (HEBARIN) according to the unified surveillance program in Hebei province.WHONET 5.6 was used to review,analyze and summarize the surveillance data.The results were interpreted according to CLSI guideline 2014.Results A total of 2 408 strains of S.pneumoniae were included in this analysis.S.pneumoniae was the third most frequently isolated gram positive bacteria.More than 95％ of these S.pneumoniae strains were susceptible to vancomycin and moxifloxacin.However,96.4％,89.3％ and 67.4％ of these strains were resistant to erythromycin,clindamycin,and trimethoprim-sulfamethoxazole,respectively.The antimicrobial susceptibility profile was similar between the strains isolated from adults and those isolates from children.Conclusions The antimicrobial resistance profile ofS.pneumoniae isolates in Hebei Province is generally consistent with the nation-wide data,except higher resistance level to a few antimicrobial agents.We should be alert to and control the emergence of resistant S.pneumoniae.
