Objective To assess the noninvasive index for diagnosing the degree of esophageal varices (EV) in patients with hepatitis B virus (HBV)-related cirrhosis. Methods The clinical data of 112 patients with HBV-related cirrhosis were studied retrospectively. The patients were divided into non-EV (NEV) group (30 cases) and EV group (82 cases) according to the results of gastroscopy. In EV group, there were mild varices in 21 cases (mild EV group), moderate varices in 47 cases (moderate EV group) and severe varices in 14 cases (severe EV group). The age, gender, platelets, glutamyl transpeptidase, prothrombin time, albumin, bilirubin, portal vein diameter, spleen vein diameter and thickness of spleen were compared, and the relationship was analyzed between each index and EV. Results There were no statistical differences in gender, age, albumin, bilirubin, prothrombin time and glutamyl transpeptidase between NEV group and EV group (P>0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in EV group were significantly higher than those in NEV group:(14.1 ± 3.1) mm vs. (10.6 ± 2.3) mm, (8.9 ± 2.1) mm vs. (7.6 ± 1.6) mm and (4.8 ± 0.9) mm vs. (3.8 ± 1.0) mm, the platelets in EV group was significantly lower than that in NEV group:(86.8 ± 20.2) × 109/L vs. (163.5 ± 18.1) × 109/L, and there were statistical differences (P<0.01 or<0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in moderate EV group and severe EV group were significantly higher than those that in NEV group and mild EV group: (13.5 ± 2.1) and (14.8 ± 3.6) mm vs. (10.6 ± 2.3) and (11.2 ± 3.1) mm, (8.3 ± 2.1) and (9.1 ± 1.1) mm vs. (7.6 ± 1.6) and (8.1 ± 1.9) mm, (4.7 ± 1.1) and (4.9 ± 0.9) mm vs. (3.8 ± 1.0) and (4.1 ± 1.2) mm, the platelet levels were significantly lower than those in NEV group and mild EV group: (72.8 ± 11.6) × 109/L and (63.8 ± 15.6) × 109/L vs. (163.5 ± 18.1) × 109/L and (100.2 ± 10.3) × 109/L, and there were statistical differences (P<0.05). The area under curve of response operating characteristic for predicting the presence of moderate and severe EV with portal vein diameter and platelets were 0.719 and 0.735, and the cut off value were 14 mm and 69 × 109/L. Conclusions The portal vein diameter and platelets can predict the presence of moderate and severe EV in patients with HBV-related cirrhosis.

AIM: To study the effects of dietary factor on liver gene expression profile in apoE~(-/-)/LDLR~(-/-)/Lepr~(db/db) mice and atherogenesis. METHODS: The gene expression profile was determined by using cDNA microarray. Total plasma TC and TG level were measured with COD-PAP and GPO-PAP methods respectively. The morphological characters of the aorta were also observed. RESULTS: Among the 4000 target genes, 78 and 114 genes were up-and down-regulated, respectively, in treble genes mutants fed with high fat high cholesterol diet compared with that of regular chow littermates, including lipid metabolism, carbohydrate, cell skeleton and immune related genes. Atherogenic diet induced severe plasma hyperlipidemia even in the early stage and also accelerated atherogenesis in the treble genes mutant mice. CONCLUSION: The data suggest that atherogenic diet aggravates abnormal plasma lipid metabolism and induces severe hyperlipidemia, and atherogenesis in the treble genes mutant mice as well.

Objective To observe the clinical efficacy of Zishen Pingchan Granules in treating non-motor symptoms (NMS) of Parkinson disease (PD). Methods A randomized, double-blind, placebo-controlled trial was used. 124 patients with PD were randomly divided into the treatment group (n=62) and the control group (n=62). Patients not yet taking Western medicine were suspended the application of Western medicine, receiving direct TCM treatment. Patients who had already taken Western medicine were added TCM on the basis of original medicine dosage and method. The treatment group was given Zishen Pingchan Granules, while the control group was treated with placebo granule, once a bag, twice a day. The treatment lasted for 12 weeks. The clinical efficacy was assessed by using unified PD rating scale (UPDRSⅡ–Ⅲ), the scale for outcomes in PD for autonomic symptoms (SCOPA-AUT), Parkinson disease sleep scale (PDSS) and dosage of levodopa. Results The UPDRSⅡ and UPDRS Ⅲscores of the treatment group and the control group after 4, 8, and 12 week of treatment had no difference at each time point compared with before treatment (P>0.05). There was no statistical significance in scores of UPDRSⅡ and UPDRSⅢ after treatment (P>0.05). Efficacy of SCOPA-AUT in treatment group after treatment was significantly better than the control group; There was statistical significance in constipation, salivation, nocturia and sweating in SCOPA-AUT between the two groups after treatment (P<0.05). Compared with before treatment, PDSS scores in treatment group after 8 and 12 weeks of treatment increased significantly (P<0.05). After 4, 8, and 12 weeks of treatment, PDSS scores in treatment group were much higher than control group (P<0.01). By comparing PDSS score in the two groups before and after treatment, it showed that treatment group had better efficacy in extending the time to sleep, reducing nocturia, nightmares, and hallucinations (P<0.05). After 12 weeks of treatment, dosage of levodopa in control group increased significantly, which treatment group was much lower than the control group (P<0.05). Conclusion Zishen Pingchan Granules can improve the autonomic dysfunctionin and sleep quality of PD patients, and can significantly reduce the dosage of levodopa.

Objective To investigate the clinical and pathological features of gastric cancer with ovarian metastasis and to analyze the reasons for its misdiagnosis. Methods There were 52 cases of gastric cancer with ovarian metastasis who had pathologic diagnoses from Jan. 1990 to Jun. 2004, whose clinical datum, pathological classification and the reasons for misdiagnosis were reviewed retrospectively and analyzed. Results The average age of the patients was 40.15?1.28 ( the ages ranging from 22 to 64 ). These patients's first symptoms and signs often were a metastatic ovary cancer. The main ultrasonographic findings were either a complex type of mass with both solid and cystic characteristics or only solid one, most of which accompany hydroperitonia, and among them metastatic ovary tumors on both sides reached 76.9 %. The serum CA125 levels increased, amounting to ( 99.85?14.23)U/mL on the average. It was greatly lower than a primary ovarian cancer(P

Objective:To identify BSG single nucleotide polymorphisms (SNPs) in Chinese Han population. Methods:Peripheral blood samples were collected from 48 unrelated healthy Chinese Han subjects. Sequences at the BSG locus, including the promoter region, all exons and exon-intron boundaries were ampliifed, sequenced and followed by Hardy-Weinberg equilibrium test and linkage disequilibrium (LD) analysis.
Results:A total of 19 SNPs were identiifed, 2 of which two were novel. Genotype distributions of all SNPs were consistent with Hardy-Weinberg equilibrium. Four haplotype blocks were constructed throughout the gene locus, and 9 haplotype tag SNPs (htSNPs) were inferred. Distribution of SNPs was in accordance with the neutrality theory in Chinese Han population. Conclusion:For the ifrst time, systematic identiifcation of BSG SNPs in the Chinese Han population has been done, and 9 htSNPs are identified. Our study has provided basis for further genetic association studies for related diseases as wel as pharmacogenetics study for drug response in Chinese Han population.

Objective To analyze the clinical features of unilateral oculomotor nerve palsy caused by multiple myeloma(MM).Methods A 79-year-old female diagnosed MM for 3 years was admitted due to the disease relapse.The patient presented left oculomotor nerve palsy,bone marrow biopsy showed 4.5％ of myeloma cells,the serum level of λ light chain was up to 18 g/L,and brain CT/MRI scan revealed left parasphenoidsinus lesion.A diagnosis of relapsing intramedullary and extramedullary MM,IgGλ type,stage ⅢA was made.Ten cases were retrieved from literature since 1990,the clinical features of 11 cases were analyzed as follows.Results Among 11 cases of unilateral oculomotor nerve palsy caused by MM,7 were males and 4 females with a mean age of (60 ± 12) years (40-79 years).The sub-types of MM were IgG type (7 cases),IgA type (2 cases),biclonal of IgG and IgA type (1 case),and IgD type (1 case).Oculomotor nerve palsy was presented as the initial manifestation of MM in 9 cases,as a sign of relapse of MM in 1 case,and during MM treatment in 1 case.In 7 cases,oculomotor nerve was the only cranial nerve involved,while in other 4 cases,the Ⅳ,Ⅴ,Ⅵ cranial nerves were also involved.Neuroimaging revealed parasphenoid sinus lesions in 9 cases,and myeloma meningitis in 2 cases.Most of the reviewed cases achieved significant clinical improvement after chemotherapy and/or radiotherapy,except 2 cases with myeloma meningitis.The case in our department was improved significantly and rapidly after receiving chemotherapy with bortezomib.Conclusion MM should be considered when unilateral oculomotor nerve palsy is presented with or without the history of MM,the disease is sensitive to chemotherapy in most circumstances.

Salmonella enterica serovar Choleraesuis strain C500 is a live attenuated vaccine that has been widely used in Chi‐na for over 50 years to prevent piglet paratyphoid .However ,as C500 is obtained by chemical methods ,the genetic background of this strain remained unclear .In this study ,we compared the genomic differences between the virulent reference strain C 78‐2 and C500 by suppression subtractive hybridization combined with the mirror orientation selection method (MOS‐SSH ) .Six genes (asr ,ydgF ,ydgD ,ydgE ,rpoS ,and ptsG) were lost in C500 strain .Using real‐time PCR analysis ,we demonstrated that the genes regulated by rpoS ,a vital transcriptional regulator playing an important role in Salmonella infection ,were downregulated in C500 .Additionally ,the virulence of the rpoS mutant strain C78‐2ΔrpoS was 100 000 times lower than the parental strain in BALB/c mice .So loss of rpoS gene is the major factor leading to the attenuation of C500 strain .

5 fold) were noted.Six significant differential proteins in gel were identified by LTQ-ESI,e.g.endoplasmin precursor,acidic leucin-rich nuclear phosphoprotein 32 family member A,serotransferrin precursor,stress-70 protein precursor,fibronectin precursor,complement C3 precursor,fibrinogen gamma polypeptide.CONCLUSION: The protein profile of apoE-/-/LDLR-/-mouse liver exhibits significant difference compared to that of WT mice.The results imply that lipid metabolism relative polygenetic mutation contributes to the alteration of mouse liver protein expression profile,especially that lipid metabolism related perhaps participates in dysfunction in lipid metabolism during atherogenesis.

AIM:To clarify the effects of high fat/cholesterol diet on lipid metabolism and atherogenesis in treble genes mutant mice.METHODS:ApoE-/-/LDLR-/-/Leprdb/db mice were generated by cross apolipoprotein E,lower density lipoprotein receptor gene knockout mice with leptin receptor gene spontaneous point mutants.The mice were fed with high fat/cholesterol diet from 22-day-old.The total plasma cholesterol(TC),triglyceride(TG)and glucose levels were measured and pathological changes of aorta intima and liver were analyzed.RESULTS:A significant elevated TC,TG and glucose levels in plasma with progress of time in young treble gene mutant mice were observed,which were higher than that in ApoE-/-/LDLR-/-and Leprdb/db mutants.At time of only 2 weeks after fed with high fat/cholesterol diet,TC and TG levels reached(106.75?3.40)mmol/L,(9.12?1.35)mmol/L,respectively in treble gene mutant mice,4.33-and 2.36-fold higher than those in treble genes mutants fed with normal chow diet.The levels were continuously increased until final experimental point.Intima of the aorta appeared with various injuries such as edema,desquamation of the endothelial cells,foam cell formation,rupture of IEL in local regions of root and arch areas of aorta at 2 weeks after fed with high fat/cholesterol diet.Microscopic pathological complex of significant local intima incrassation and fatty change of the liver were observed in the mutants that fed with high fat/cholesterol diet for 8 weeks.Injuries of aorta were severe than normal dietetic control group.CONCLUSION:High fat/cholesterol diet as a key dietary factor is significant aggravated lipid metabolism abnormity,promotes early damage of aorta and process of atherogenesis in the treble genes mutants.
