Objective To master the prevalence trend of Kaschin-Beck disease in Xinghai county (Shanglujuan and X.ialujuan village of Tangnaihai township) from 2003 to 2008 in order to understand changes of selenium level of internal and external environments. Methods According to monitoring method on national Kaschin-Beck disease,we carried out epidemical investigation,clinical examination and X-ray photograph on school children aged 7-12 in Xinghai county,a monitoring region,and collected samples of hair and grain. The content of selenium was detected by 2,3-naphthalene fluorescence. Results From 2003 to 2008,in Shanglujuan village,the prevalence rate of clinic examination was fluctuating between 0(0/34)-17.14%(6/35); the detectable rate of X-ray examination was fluctuating between 11.11% (3/27)-20.59% (7/34),the prevalence rates of metaphysis and extremities were fluctuating between 0 (0/27)-13.21%(7/53) and 2.63% (1/38)-11.43% (4/35). In Xialujuan village,the prevalence rate of clinic examination was fluctuating between 2.94% (1/34)-13.33% (6/45); the detectable rate of X-ray examination was fluctuating between 26.67% (12/45)-43.63%(24/55),the prevalence rate of metaphysis and extremities were fluctuating between 8.33% (6/72)-26.47% (9/34) and 13.33% (6/45)-38.18% (21/55). The selenium contents in hair samples were (139.92±92.27),(134.98±63.77)μg/kg respectively in Shanglujuan and Xialujuan village in 2003; the selenium contents in grain samples were (12.90± 7.18),(14.58±9.90)μg/kg respectively in Shanglujuan and Xialujuan village in 2005. Conclusions The prevalence state of Kaschin-Beck disease in national monitoring region is rigid and pathogenetic factors of Kaschin-Beck disease are active. Selenium levels of internal and external environments are low in this region.

Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

OBJECTIVETo investigate the relationship between the second to the fourth digit ratio (2D:4D) and body mass index (BMI) in infertile men of the Han ethnic group in Ningxia.

METHODSUsing anthropometry, we calculated the mean ratio of 2D:4D and BMI of 197 infertile men and 148 normal healthy male controls, followed by analysis of their relationship.

RESULTSThe BMI was correlated positively with the 2D:4D ratio of the left hand in the infertile men (P < 0.05) and in the patients with a higher 2D:4D ratio of the left hand (P < 0.05), but negatively with the 2D:4D ratio of the righ/left (Dr-1) (left: P < 0.01; Dr-l: P < 0.05). The mean 2D: 4D ratio and BMI were both lower in the normal control than in the infertile men, with statistically significant differences in BMI (P < 0.05) and the 2D:4D ratio of the left hand (P < 0.05).

CONCLUSIONThere is a correlation between the 2D:4D ratio and BMI in infertile men.

0.05).However,the shorter the history of the disease,the better the efficacy of the treatment.The younger the patient was,the better the efficacy of the treatment.Conclusions Vulva dystrophy can be treated with focused ultrasound effectively and safely.This approach appears to be a new promising treatment method.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

OBJECTIVETo observe the effects of fosinopril (FOS) on proliferation and secretion of extracellular matrix of rat glomerular mesangial cell induced by LPS.

METHODSIn vitro culture method for glomerular mesangial cells (GMC) of rat was established and passages 3 - 10 of the cells were used in the experiment after identification. The experiment included the following 5 groups: control group (Ctrl), LPS group (LPS), high, medium and low dose FOS groups (FOS1, FOS2 and FOS3 groups, respectively). GMC proliferation was detected by methyl thiazolyl tetrazolium (MTT) incorporation method at 24 and 48 h; the changes of laminin (LN), fibronectin (FN) and ColIV protein secretion was detected by the enzyme-linked immunosorbent assay (ELISA). The changes of LNbeta(2) mRNA expression was detected by semi-quantitative real-time RT-PCR.

RESULTS(1) LPS could induce the mesangial cell proliferation, FOS inhibited this effect of proliferation induced by LPS. (2) Mesangial cells could secrete some extracellular matrix (ECM) protein in normal culture medium, mesangial cell secreted ECM protein was significantly higher in LPS group than that in Ctrl group (P < 0.01), but significantly lower in all FOS groups than that in LPS group (P < 0.01). (3) Mesangial cell could express LNbeta(2) mRNA in normal culture medium, LNbeta(2) mRNA expression was significantly higher in LPS group than that in Ctrl group at all time points, but was significantly lower in FOS group than that in LPS group.

CONCLUSIONSLPS could induce increased secretion of the ECM, including LN, FN, ColIV; FOS could inhibit the secretion of ECM in GMC in a dose-dependent manner at mRNA and protein levels.

OBJECTIVETo explore the changes of cytokines including TNFalpha, TGFbeta1 and nitrogen monoxide, and endotoxin in the serum of chronic severe hepatitis after the treatment of ALSS, and to evaluate further the value of ALSS in the treatment of chronic severe hepatitis.

METHODSForty two patients were screened. The changes of TNFalpha, TGFbeta1, nitrogen monoxide and endotoxin were detected respectively. The relationship between the cytokines and the severity and prognosis were further analyzed.

RESULTSALSS was effective to decrease the serum concentration of cytokines. TNFalpha dropped from (481.57+/-229.33) pg/ml to (156.46+/-78.12) pg/ml (P < 0.05). TGFbeta1 from (44.09+/-31.73) ng/ml to (27.77+/-23.28) ng/ml (P < 0.01), endotoxin from (1.05+/-0.37) Eu/ml to (0.28+/-0.22) Eu/ml (P < 0.001). NO from (71.15+/-33.09) micromol/L to (58.11+/-29.30) micromol/L (P < 0.001). Before the therapy endotoxin was related with TNFalpha and total bilirubin, while after the therapy, NO was related with protime and aminonemia.

CONCLUSIONHigh level of endotoxin and nitrogen monoxide in serum plays an important role in hepatocyte damage of chronic severe hepatitis. The changes of serum endotoxin TNFalpha, TGFbeta1 and nitrogen monoxide level in patients with chronic severe hepatitis can be used to judge the severity and prognosis of severe hepatitis. ALSS is a reliable hepatic support device for chronic severe hepatitis
