ObjectiveTo observe clinical effect of proteinuria treatment in hypertension and type 2 diabetes with enalaprilat joint losartan. Methods72 cases of hypertension and type 2 diabetes with proteinuria patients were divided into two groups randomiy,losartan and enalaprilat combination for the treatment group( n =36) ,losartan alone for the observation group( n =36) ,treatment 14 weeks. Observed two groups of blood pressure and 24h after treatment urinary albumin excretion rate. ResultsTwo groups of blood pressure than before treatment were reduced significantly(P ＜ 0.05), but after treatment between the two groups, the difference was not statistically significant (P ＞ 0.05 ).Two groups of patients after 14 weeks treatment, average 24h urine albumin excretion rate form( 105.2 ± 27.3 ) μg/min, ( 110. 3 ± 28.0) μg/min fell to(72.6 ± 26.5 ) μg/min, ( 87.5 ± 24.9 ) μg/min ( P ＜ 0. 01 ), the treatment group reduced more significant(P ＜0.05). ConclusionEnalaprilat joint losartan treatment at the same time,the effective step-down pressure, could improve the type 2 diabetes patients with early renal damage, and it suggested the early renal damage patients should be combined antihypertensive therapy as soon as possible.

Objective To analyze the effect on reproductive potential of salpingectomy in child-bearing period women.Methods Two hundred and forty-six tubal pregnancy patients were chosen,among whom 164 patients performed salpingectomy were classified as research group,and 82 patients retained ipsilateral tubal through conservative treatment were classified as control group.The levels of sex hormone,ovarian volume,sinus number of follicle,ovulation rate,reproductive outcome and reproductive status were compared between 2 groups.Seven patients were lost in research group,and 3 patients were lost in control group.Results One,three and six months after β-human chorionic gonadotrophin (β-hCG) put back,the serum levels of follicle stimulating hormone (FSH),luteinizing hormone (LH) in research group were significantly higher than those in control group,FSH:(10.00 ±4.82) U/L vs.(6.69 ± 2.71) U/L,(9.11 ± 3.77)U/L vs.(6.81 ± 2.80) U/L,(8.30 ± 3.49) U/L vs.(6.41 ± 2.41) U/L;LH:(8.74 ± 3.56) U/L vs.(6.10 ± 2.59)U/L,(9.42 ± 3.09) U/L vs.(5.79 ± 2.10) U/L,(7.96 ± 2.53) U/L vs.(6.50 ± 2.71) U/L,and there were statistical differences (P ＜ 0.05).One and three months after β-hCG put back,the serum levels of estradiol (E2) and anti-Mullerian hormone (AMH) in research group were significantly lower than those in control group,E2:(111.44 ± 22.24) pmol/L vs.(128.22 ± 24.01) pmol/L,(108.74 ± 21.67) pmol/L vs.(126.30 ± 23.78) pmol/L;AMH:(3.22 ± 0.85) μ g/L vs.(3.64 ± 0.87) μ g/L,(3.67 ± 0.94) μ g/L vs.(3.83 ± 1.12) μ g/L,and there were statistical differences (P ＜ 0.05).Six months after β-hCG put back,there was no statistical difference in the serum levels of E2 and AMH:(127.85 ± 24.42) pmol/L vs.(131.28 ± 25.54) pmol/L and (4.35 ± 1.34) μ g/L vs.(4.47 ± 1.76) μ g/L,P ＞ 0.05.In salpingectomy patients,the ovarian volume and the sinus number of follicle at lesion side (salpingectomy side) after treatment of 6 months were significantly lower than those in no lesion side:(8.86 ± 2.36) cm3 vs.(9.74 ± 2.31) cm3 and (5.10 ± 1.14) pieces vs.(7.26 ± 2.52) pieces,and there were statistical differences (P ＜ 0.05).After treatment of 2 years,the rate of ectopic pregnancy in control group was significantly higher than that in research group:12.66％ (10/79) vs.5.10％(8/157),and there was statistical difference (P ＜ 0.05).Especially,the patients who retained ipsilateral tubal conservative treatment had higher ectopic pregnancy rate:8.86％ (7/79) vs.0,and there was statistical difference (P ＜ 0.05).Conclusions Salpingectomy can affect the reproductive potential,but it can decrease the probability of ectopic pregnancy.Whether patients with tubal pregnancy need to be treated by salpingectomy,depends on the extent of tubal lesions and fertility desire of the patients.

Objective To investigate the performances and characteristics of femoro-acetabular impingement (FAI)on MSCT. Methods Hips jointed MSCT scans of 109 cases (as case group)and the other 120 cases (as control group)were analyzed retrospec-tively,to analyze the anatomy and osseous abnomality of FAI.Alpha angle,offset,CE angle were measured.The data were tested by using t test and ANOVA test.Results There were 57 cases of osseous protuberance at the femoral head and neck joint,26 cases of the offset reduction,17 cases of over-coverage acetabulum,41 cases of over-deep acetabulum,20 cases of acetabular retroversion,57 cases of subcortical cystic degeneration at the femoral head and neck joint and 22 cases of subchondral cystic degeneration at the ace-tabulum margin.Significant statistical differences were found between case group and control group in alpha angle value,offset and CE angle (P<0.05).Multiple comparisons demonstrated that except results between the value of alpha angle of Cam-type and Mixed-type(P=0.071),Pincer-type and the control group(P=0.083)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrated that except result between the value of offset of Cam-type and Mixed-type(P=0.561)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrate that except results between the value of CE angle Pin-cer-type and Mixed-type (P=0.444),Cam-type and the control group (P=0.236)with no statistical significance,the differences be-tween any other two groups reached statistical significance (P<0.05).Conclusion Different type of FAI has its unique anatomical features.Alpha angle,offsetand CE angle for the diagnosis of FAI have important reference values.

Objective To investigate the relationship between age and biochemical markers of bone absorption and bone formation in old men. Methods Urinary deoxypyridinoline crosslinks (Dpd),calcium (Ca),serum bone g1aprotein (BGP),procollagen I C terminal peptides (PICP) and testosterone (Tes) were determined by ELISA. Urinary hydroxyproline (Hyp) was tested by HPLC,and bone specific alkaline phosphatase (BALP) was assayed by electrophoresis.

OBJECTIVE To investigate the effect and mechanisms of chrysophanol on the expression of c-fos and c-jun mRNA induced by ammonia chloride(NH4Cl) in mouse astrocytes. METHODS Primary mouse astrocytes were cultured with NH4Cl 5 mmol·L-1+chrysophanol 0.1,1.0 or 10.0 mg·L-1 ,or NH4Cl 5 mmol · L- 1+extracellular regulated kinase1/2(ERK1/2) inhibitor UO126 10 mmol · L- 1 and NH4Cl 5 mmol · L-1+p38 mitogen-activated protein kinase(p38 MAPK)inhibitor SB239063 10 mmol · L-1 for 48 h. The levels of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD),malondaldehyde(MDA), nitric oxide(NO)and nitric oxide synthase(NOS)were detected by UV spectrophotometry. The phos?phorylation levels of ERK1/2 and p38 MAPK were detected by Western blotting. The expression of c-fos and c-jun mRNA was detected by RT-PCR. RESULTS Compared with NH4Cl 5 mmol · L- 1 group, ammonia-induced astrocytes oxidative stress was improved by chrysophanol (1.0 and 10.0 mg · L-1). The content of MDA and NO and the activity of NOS were reduced(P<0.05). The activity GSH-Px and SOD was increased(P<0.05). The phosphorylation level of ERK1/2 and p38 MAPK induced by ammonia was reduced in chrysophanol groups (P<0.05). Ammonia-induced c-fos and c-jun mRNA expression downregulation was reversed by chrysophanol (0.1,1.0 and 10.0 mg · L-1)and UO126 and SB239063(P<0.05). CONCLUSION Chrysophanol may improve the downregulated expresion of c-fos and c-jun mRNA in mouse astrocytes exposed to NH4Cl by anti-oxidative stress by inhibiting the ERK1/2 and p38 MAPK phosphorylation.

Objective To investigate the effects of sevoflurane anesthesia on learning and memory functions and S100β protein in anaplasis in the 7-day-old rat.Methods 48 SD rats of both sexes aged 7-day-old weighing 1 2-1 6 g were randomly divided into 3 groups (1 6 rats in each group):group A and group B inhaled 3 ％ sevoflurane in oxygen(1L/min) for 6h and 2h respectively; group C inhaled oxygen(1L/min) only.After inhalation,the effects of sevoflurane anesthesia on learning and memory function were assessed by Morris water-maze test and Y-maze test from 16d to 24d.The rats were killed in the day of 8d and 25d respectively,and the blood were collected for the expression of serum concentration S100β protein by enzyme-linked immunosorbent assay.Results (1) Results of Morris water-maze test:Compared with group C,escape latency prolonged in group A and group B in 17-20d(P ＜ 0.05 or 0.01) ;escape latency prolonged in group A compared with group B in 19-20d(P ＜ 0.01) ;but there were no significant differences in the probe time in original platform quadrant and the frequency of crossing original platform among three groups(P ＞0.05).(2) Result of Y-maze test:In 22d,the total reaction time of group A and B were longer than group C (P ＜0.05 or 0.01),and the error number was increased in group A and B compared with group C(P ＜ 0.01) ; while in 23-24d,there were no significant differences between every index of each groups (P ＞ 0.05).(3) Results of the blood serum index:In 8d,serum concentration of S100β protein was significantly increased in group A and B compared with group C (P ＜0.01),and serum concentration of S100β protein was significantly increased in group A compared with group B (P ＜ 0.05) ; But there were no significant differences in serum concentration of S100β protein of each groups in 25d(P ＞ 0.05).Conclusion Sevoflurane anesthesia in the 7-day-old rat can temporarily decrease the ability of learning and memory functions in the length of inhalation time dependent manner,and the mechanism may be related to the increased expression of serum concentration of S100β protein transiently.

One strain of PRRSV was isolated from tissue of piglets died of obvious respiratory syndrome and high fever.It was identified as a strain of American type PRRSV by serological test and gene sequencing.According to American type PRRSV VR-2332,we designed 3 pairs of primers to aim directly at N gene,GP5 gene and variation sequence of NSP2.The results of sequence analysis indicated a discontinuous deletion of 30 amino acids in nonstructural protein 2 (NSP2).N and GP5 gene is conservative relatively.

The aim of this project is to establish a fibroblast growth factor-21 (FGF-21) signaling pathway targeted cell model, for screening a class of FGF-21 receptor agonists as anti-diabetic candidates. FGF-21 requires beta klotho transmembrane proteins as co-receptor for the activation of tyrosine kinase FGF receptor (FGFR) signaling, thereby activating a series of intracellular signaling pathways and regulating gene transcription for glucose metabolism. Firstly a recombinant plasmid expressing co-receptor beta klotho and EGFP reporter genes was constructed. After introducing the recombinant plasmid into package cells, the cell culture supernatant was used to infect 3T3-L1 cells, which were then screened for stably expressing beta klotho gene. Administration of FGF-21 increased the expression of GLUT1 and stimulated GLUT1-mediated glucose uptake. This novel cell model can be conveniently used in high-throughput drug screening of FGF-21 or FGF-21 analogues.

FGF21 (fibroblast growth factor 21) is a recently described member of the FGF family. It has been previously demonstrated that FGF21 is a potent regulator of glucose homeostasis. To improve stability of FGF21 for better efficacy, a new form of recombinant FGF21 was generated by fusion of a full length FGF21 gene and the Fc fragment of human IgG4 with flexible linker sequence. To examine the glucose regulation activity of FGF21-L-Fc, 3T3-L1 pre-adipocytes were differentiated into adipocytes, and glucose uptake activity of FGF21-L-Fc was examined by glucose oxidase and peroxidase (GOD-POD) assay. The results showed that in comparison with wild type FGF21, FGF21-L-Fc was more potent in stimulation of glucose uptake by 3T3-L1. In vivo studies on the modified protein demonstrated that FGF-L-Fc had a better efficacy in lowering blood glucose of the STZ-induced diabetic animals and controlled glucose level for a longer time. The results provided a sound basis for further studies.
