Objective To explore the correlation between intestinal mucosal immune barrier and pathogenesis of pigment gallstone and its possible mechanism.Methods Eighty guinea pigs were randomly divided into control group(group CON),pigment gallstone group(group PS),and intestinal mucosal protection group(group GLN).The guinea pigs were fed with normal diet in group CON,pigment gallstonein during diet in group PS,and glutamine-supplemented diet in group GLN for 8 weeks.The guinea pig model of pigment gallstone was established.The incidence of pigment gallstone was detected.The morphology of intestinal mucosa was observed,and the numbers of CD3~+T cell,CD40~+B cell,and IgA~+ plasma cell were counted.Results The incidence of pigment gallstone was significantly higher in group PS than in groups GLN and CON(P＜0.05).Compared with group CON,the intestinal wall was significant thinner and represented obvious signs of inflammation in group PS,and the numbers of CD3~+ T cell,CD40~+ B cell,and IgA~+ plasma cell significantly decreased(CD3~+ T cell,21.8±2.5 vs 11.1±3.4,P＜0.01;CD 40~+B cell,12.9±2.0 vs 10.7±3.6,P＜0.01;IgA~+ plasma cell,12.4±3.4 vs 10.7±3.5,P＜0.01).The signs of inflammation were less severe in group GLN than in group PS.There were significant differences in the numbers of CD3~+ T cell,CD40~+ B cell,and IgA~+plasma cell between groups GLN and PS.Conclusion Intestinal barrier dysfunction,including mechanical barrier and immune barrier,is involved in the formation of pigment gallstone.Glutamine has proved to improve the function of intestinal mucosal barrier and decrease the incidence of pigment gallstone.

Objective To compare the clinical effect of needle knife therapy and traction for treatment of cervical spondylosis .Methods 156 patients with nerve root type of cervical spondylosis patients definitely diag -nosed,randomly divided into two groups ,the treatment group of 78 cases,with small needle knife therapy;the control group of 78 cases,the cervical traction therapy ,combined with traditional Chinese medicine .The clinical efficacy was compared between the two groups .Results The treatment group 70 cases were cured(89.6%),the total efficiency of 96.9%;control group 44 cases were cured(56.7%),the total efficiency of 83.3%.The cure rate and total effective rate was significantly better than the control group (χ2 =22.02,11.57,all P<0.05).Conclusion The needle knife therapy to treat cervical vertebra disease is better than that of cervical traction ,has good clinical curative effect .

Metabolic syndrome (MetS) is a serious threat to public health worldwide with an increased risk of developing type 2 diabetes, cardiovascular diseases and all-cause morbidity and mortality. In this study, a urinary metabolomic approach was performed on high performance liquid chromatography quadrupole time-of-flight mass spectrometry to discriminate 36 male MetS patients and 36 sex and age matched healthy controls. Pattern recognition analyses (principal component analysis and orthogonal projections to latent structures discriminate analysis) commonly demonstrated the difference between MetS patients and no-MetS subjects. This study found 8 metabolites that showed significant changes in patients with MetS, including branch-chain and aromatic amino acids (leucine, tyrosine, phenylalanine and tryptophan), short-chain acylcanitine (tiglylcarnitine), tricarboxylic acid (TCA) cycle intermediate (cis-aconitic acid) and glucuronidated products (cortolone-3-glucuronide and tetrahydroaldosterone-3-glucuronide). The candidate biomarkers revealed in this study could be useful in providing clues for further research focusing on the in-depth investigation of the cause of and cure for MetS.

AIM:To investigate the effect of berberine on IL-1 or tumour necrosis factor (TNF) induced polymorphonuclear leucocyte(PMN)-endothelium adhesion and adhesion molecules.METHODS:Based on the model of human umbilical vein endothelial cell (HUVEC), this study adopted Rose Bengal Stain, cell ELISA, immunocyto-chemical techniques to investigate the effect of berberine on PMN-endothelium adhesion and the expression of cell adhesion molecules (CAMs).RESULTS:Berberine inhibited IL-1, TNF-induced HUVEC adhesion for PMN when pretreated HUVEC and antagonised IL-1, TNF-induced upregulation of ICAM-1 on HUVEC. Meanwhile, TNF-stimulated PMN adhesion for HUVEC and CD18 upexpression on PMN was diminished in the presence of berberine.CONCLUSION: Inhibite PMN-endothelium adhesion by downregulating the CAMs expression to inhibite PMN migration across endothelium is one of the mechanisms of antiinflammation of berberine.

A spectrophotometric method for the determination of calcium in milk, hair and urine was developed using metal complezing dye orthocresolphth-alein complexone(OCPC).The organic matter in the tested sample was destroyed by digestion. An aliquot of the digested solution was mixed with color developing reagent, alkaline OCPC, cantaining 8-quinolinol to suppress interference such as magnesium, and the absorbance was measured at 570 nm.The coefficients of variation were 0.87, 3.6 and 1.2% for milk, hair and urine samples; and the analytical recoveries of calcium from milk, hair and urine averaged 100.4, 101.0 and 98.5% respectively. The calcium content of milk and hair determined by this method was closely correlated with that of the ICP-AES method (r =0.994, p

Objective:To study the cytokine mechanism of Jiawei Xuanfei Toujie Ji(JXT)therapy to influenza infected mouse.Methods:Mice were inoculated intranasally with mouse lung-adapted influenza virus strain(FM1),and were treated with JXT. At 5th days after postinoculation were sacrificed, and IL-2,TNF-?,IL-6,IFN-? in their sera were measured with ELISA kits, their lungs sections were stained with hematoxylin and eosin.Results:Compared with model group ,the levels of IL-2 and IFN-? in JXT group were dramatically higher,and the levels of TNF-? and IL-6 were lower,and pathological effects of influenza pneumonia showed less lung injury.Conclusion:Regulative effects on cytokine may be one of the factors that JXT decrease the pathogenesis of influenza-induced acute lung injury.

OBJECTIVE: To observe the effects of ginsenoside (Gs) and berberine (Ber), two kinds of active components of traditional Chinese herbal medicine, on transforming growth factor-beta1 (TGF-beta1) and prostaglandin E2 (PGE2) in PG cells. METHODS: Co-culture system of human lung carcinoma cell line PG and human T lymphocyte cell line Jurkat was established. PG cells were treated with Gs (100 microg/ml) and Ber (10 mug/ml) for twenty-four hours, and then cocultured with Jurkat cells. After 24-hour coculture, the state of Jurkat cells was observed with inverted microscope. The viable count of Jurkat cells was detected by trypan blue staining after 6- and 24-hour coculture, and the apoptosis of Jurkat cells was evaluated by flow cytometry. PG cells were treated with 100, 50, 25 microg/ml Gs and 10, 5, 2.5 microg/ml Ber respectively, and the content of TGF-beta1 and PGE(2) in PG cells was detected by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) method. RESULTS: After coculture with PG cells treated with Gs and Ber, the number of Jurkat cells was less than blank control group, and the apoptosis rates of Jurkat cells in Gs- and Ber-treated groups were higher than blank control group. Gs and Ber could promote the secretion of TGF-beta1 in PG cells, but could not change the level of PGE(2). CONCLUSION: Gs and Ber can promote the growth inhibition and apoptosis of Jurkat cells induced by PG cells, which may be related to the up-regulation of Gs and Ber on TGF-beta1 secretion in PG cells.

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.
