Objective To analyze the allele frequencies of 5 short tandem repeat(STR)loci(D12S313,D12S304,D12S1640,D12S1708 and D12S1583)on chromosome 12 among Kashin-Beck disease(KBD)patients and the control population living in the area suffered from KBD.Methods Fifty KBD patient8 and 50 non-KBD patients were chosen in endemic afea of Shaanxi Province,5 STR loci on chromosome 12 were genotyped by the technology of polymerase chain reacfion(PCR)and capillary electmphoresis.The pelymorphisms of STR in these popIllations were analyzed.The allele and genotype frequencies of each STR in the corresponding groups were caleulated and compared. Results In KBD group,the 5 STR loci had 8,6,7,5 and 11 types ofalleles and 17,11,15,8 and 28 genotypes, respectively;while in the control group,the number of aUele types of 5 STR loci were 6,8,6,4 and 10,the number of genotype of those loci were 13,21,14,8 and 23,respectively The allele frequence of D12S304 locus was statiBtically significant between KBD patients and controls(P<0.05),especially for the 319 bp allele(P<0.006 25). Conclusion There is an association between D12S304 locus and KBD.The 319 bp allele might play the key role.

OBJECTIVETo explore the intervention of Fagopyrum cymosum (Trev.) Meisn alcohol extract (FAE) on defecation function and motor functions of isolated colons of diarrhea-predominant irritable bowel syndrome (D-IBS) rats and to study its underlying mechanism.

METHODSThe D-IBS rat model was established by neonatal pups maternal separation (NMS) combined with intracolonic infusion of acetic acid (AA). Adult IBS rats were randomly divided into the pre-intervention control group (n = 10, with no gastrogavage), the normal saline control group (n = 10, administered with normal saline by gastrogavage), the pre-treatment model group (n = 8,with no gastrogavage),the normal saline model group (n = 8, administered with normal saline by gastrogavage), the low dose FAE group (n = 8, administered with 6 g/kg FAE by gastrogavage), the high dose FAE group (n = 8, administered with 24 g/kg FAE by gastrogavage), and the Pinaverium Bromide group (n = 8, administered with 0.02 g/kg Pinaverium Bromide by gastrogavage). All medication was performed once daily for 2 weeks. The abdominal withdrawal reflex (AWR) was employed to evaluate the visceral hypersensitivity; their loose and watery stool grade was assessed by Bristol scores for stool consistency; and their fresh feces weight was calculated. In vitro effect of different concentrations of FAE and Pinaverium Bromide (0.02 μg/mL) on spontaneous contraction and spasmodic contraction induced by acetylcholine (Ach) in rats' isolated colon were observed and the influence on the intestinal calcium channel was evaluated.

RESULTSCompared with the pre-intervention control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the pre-intervention model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased drastically (P < 0.01). Compared with the normal saline control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the normal saline model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased markedly (P < 0.01). Compared with the normal saline model group, the pain pressure threshold of 24 g/kg FAE and Pinaverium Bromide group significantly increased (P < 0.05). The loose and watery stool grade and fresh feces weight decreased obviously in the low dose FAE group, the high dose FAE group, and the Pinaverium Bromide group (P < 0.05). FAE (30, 100, 300, 1,000, and 3,000 μg/mL) and Pinaverium Bromide could significantly inhibit spontaneous contraction of isolated intestines (P < 0.05, P < 0.01), and FAE (30, 100, and 300 x 10(-6) g/mL) could remarkably inhibit their spasmodic contraction and contractile tension induced by Ach and Ca2+ respectively (P < 0.05, P < 0.01) in a concentration-dependent manner. Pinaverium Bromide also could significantly inhibit Ach and Ca2+ induced contraction.

CONCLUSIONEffective components of FAE improved the defecation function and inhibited enterospasm induced intestinal hyperactivity in IBS model rats via antagonizing calcium channel competitively and inhibiting colonic motility dose-dependently.

The PDB culture medium was selected to ferment the endophyte strain, and the secondary metabolites of endophytic fungi Penicillium polonicum were studied. Combined application of Sephadex LH-20, ODS and HPLC chromatographies over the ethyl acetate extract of the fermented culture led to the isolation of 6 compounds. By spectral methods, the structures were elucidated as [3, 5-dihydroxy-2-(7-hydroxy-octanoyl)]-ethylphenylacetate (1), (3, 5-dihydroxy-2- octanoyl)-ethyl phenylacetate (2), (5, 7-di- hydroxy-9-heptyl)-isobenzo pyran-3-one (3), 3-(hydroxymethyl) 4-(1E)-1- propen-1-yl-(1R, 2S, 5R, 6S)-7-oxabicyclo [4.1.0] hept-3-ene-2, 5-diol (4), (E)-2-methoxy-3-(prop-1-enyl) phenol (5) and p-hydroxylphenylethanol (6).

Objective To study the effect of glucocorticoid on serum interleukin(IL)-1,IL-6,transforming growth factor-?_1(TGF-?_1) and tumor necrosis factor alpha(TNF-?) in children with primary nephrotic syndrome(PNS).Methods The levels of cytokines on serum were compared in 3 different patho-type,and IL-1,IL-6,TGF-?_1 and TNF-? in serum were detected using enzyme-linked immunosorbent assay(ELISA) in 25 children with PNS before and after treatment with glucocorticoids.Results Significant difference of IL-1,IL-6,TGF-?_1 and TNF-? were found between the two group before and after the treatment(P0.05).The level of TGF-?_1 in MCD was lo-wer than that in MsPNG,FSGS before and after the treatment(P0.05),and the level of it in FSGS was higher than that in MsPNG after the treatment(P

Purpose To observe the changes of left atrial (LA) structure and function in patients with paroxysmal atrial fibrillation after radiofrequency catheter ablation by echocardiography in order to provide basis for clinical evaluation of surgery.Materials and Methods Forty-four patients with paroxysmal atrial fibrillation and treated with radiofrequency catheter ablation in PLA General Hospital from January 2015 to June 2016 were enrolled.According to whether or not to restore sinus rhythm after operation,the patients were divided into sinus rhythm group and atrial fibrillation recurrence group.The paramrters of LA including diameter,maximum and minimum volume,systolic volume,ejection fraction,active ejection fraction,conduit function index and dilatation index were measure by echocardiography before and at least 6 months after radiofrequency catheter ablation.The data were compared between and within groups.Results All patients were followed up for (6.0±0.5) months after ablation operation.29 of 44 patients (66％) maintained sinus rhythm;the anteroposterior,vertical,and left to right diameters of LA in patients with sinus rhythm after operation were significantly lower than those before operation,but the ejection fraction of LA increased (all P＜0.05).However,in patients with atrial fibrillation recurrence after operation,the volume of LA increased (P＜0.05);the diameters of LA did not show significant differences;the ejection and active ejection fraction of LA had significantly decreased (P＜0.05).Compared with patients with sinus rhythm after operation,patients with atrial fibrillation recurrence after operation were older and had higher proportion of hypertension (P＜0.05).Conclusion After ablation,the diameter of LA decreases and the ejection fraction increases in patients with sinus rhythm;the volume of LA increases and the function reduces in patients with atrial fibrillation recurrence.

Objective To study effects of fluid resuscitation on thoracoabdominal injury combined with hemorrhagic traumatic shock.Method A total of 98 patients,who were treated in Affiliated Zhongshan Hospital of Dalian University from November 2004 to December 2006,were retrospectively analyzed.The patients were diagnozed according to Surgery(fifth edition).Patients were divided into delayed fluid resuscitation group(n= 51)and immediate fluid resuscitation group(n=47).Patients in delayed fluid resuscitation group were given with balanced salt solution for the body to maintain basic requirements.Patients in immediate fluid resuscitation group were rapidly administered with a lot of isotonic crystaUoid and(or)colloid solution after admission. Hemoglobin,platelet count,hematocrit,blood lactic acid,basedeficit,preoperative resuscitation time and mortality were compared between the two groups.Paired t test and variance analysis or x~2 test were used.Results The transfusion fluid volume of delayed group and immediate group was(1586?346)ml,(3520?575)ml, respectively,with P value
