Objective To evaluate the efficacy of X-ray guided choledochoscopy via T tube tunnel and interventional treatment of residual bile duct stones.Methods Cholangiography was performed in patients suspected of residual bile duct stone with choledochoscopy via the remaining T tube tunnel,and data of 45 patients who received endoscopically treatment for the residual bile duct stones and bile duct stricture were analyzed.Results Seven patients' with adhesive bile duct stenosis were resolved by repeat rinse and dilation,but the procedure failed in 2 cases of bile duct stricture caused by scar;seven cases of common bile duct stone combined with gradeHand Ⅲ multiple hepatic cholelith were removed within 1.5 h:six cases of hepatic bile duct narrowing with multiple cholelith were taken out in 1.0 hour;six cases of grade Ⅱ and Ⅲ multiple massive choledocholith were removed with lithotrity for over 2.0 h:six cases of grade Ⅱ-Ⅳ cholelith were eliminated within 1.5 h:six cases of hepatobiliary stone were removed successfully in 30 min.Stones in 3 cases of multiple stones with intrahepatie bile duct stenosis were not taken out due to bile duct stricture;stones in 2 cases of gradeⅡand Ⅲ multiple choledocholith were not removed for T tube tunnel bleeding.Conclusion X-ray guided choledochoscopy is convenient and effective to remove residue cholelith.

Objective To investigate the effect of partial body-weight supported treadmill training ( PBW- STT) on function of lower limbs, walk function, ADL performance and quality of life of hemiplegic patient induced by cerebral infarction. Methods A total of 132 cerebral infarction patients were divided into a control group (n = 69) and a training group( n = 63) randomly. Both groups accepted routine rehabilitation therapy, and the training group accepted PBWSTT at the same time in addition. Both groups were evaluated with regard to their walking ability, func- tion of lower limbs, ADL performance and their quality of life by using Functional Ambulation Category (FAC) , Fugl-Meyer assessment (FMA) , Barthel index (BI) and SF-36 before and after rehabilitation treatment. Results The function of lower limb, walking ability, ADL performance and the quality of life of both groups were improved significantly after treatment, and those in the training group were improved to a significantly greater extent than those in the control group ( P

0.05)between the two groups.Conclu- sion The long-term outcomes of e-CHB is not markedly different compared with that of e+CHB.

OBJECTIVETo investigate the association between oral neoplasm genetic susceptibility and genetic polymorphism of p53 intron 7.

METHODSThe intron 7 ApaI polymorphism of p53 was analyzed in 95 oral neoplasm patients and 105 healthy individuals by utilizing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) genotyping assay technique, and direct sequencing was performed in 30 cases which were selected from the patients and controls by random sampling.

RESULTSIn oral neoplasms cases, haplotype combinations were T-G 43.2%, C-T 56.8%, and frequencies of genotype were T-G/T-G 15.8%, C-T/T-G 54.7%, C-T/C-T 29.5%, while in controls they were T-G 30.9%, C-T 69.1% and T-G/T-G 10.5%, C-T/T-G 41.0%, C-T/C-T 48.5%. There was a significant difference in the allelic frequency and the genotypical distributions between the oral neoplasm patients and the controls. The individuals with the T-G allele had a slight increasing neoplasm risk than individuals with C-T allele; the OR for T-G versus C-T was 1.69 (95% CI, 1.12 - 2.51). The risk of suffering from oral neoplasms was higher in the individuals of T-G/T-G genotype and of T-G/C-T genotype than in individuals of C-T/CT genotype with odds ratio of 2.48 versus 2.20.

CONCLUSIONSThere are two polymorphic points in the 7th intron of human p53 gene, which could be associated with genetic susceptibility of oral neoplasms. T-G allele may be the risk factor of oral neoplasms.

OBJECTIVEHenoch-Schonlein purpura nephritis (HSPN) and IgA nephropathy are very similar in immunopathological changes, and therefore some nephrologists considered that they are substantially one disease entity caused by IgA immune abnormalities, and IgA nephropathy is, in fact, a kind of HSPN without rashes. The present study aimed to characterize their relationship through clinico-pathological comparison between IgA nephropathy and HSPN.

METHODSThirty-one children with IgA nephropathy aged from 3 to 15 years and 120 children with HSPN aged between 4 to 15 years were enrolled in this study. Their clinical manifestations, blood biochemical test, serum immunology and follow-up data were collected and analyzed. Renal pathological findings in light microscopy, immunofluorescence and electron microscopy were analyzed and also compared between 31 children with IgA nephropathy and 32 children with HSPN.

RESULTSThe age of onset was over 12 years in 25.8% children with IgA nephropathy, but only in 10% with HSPN, and the difference was significant (P < 0.05). The clinical patterns of IgA nephropathy and HSPN were similar, but extra-renal manifestations were seen more often in HSPN, all of them had skin purpura, 59% had gastrointestinal symptoms and 47% suffered from arthralgia. While the abdominal pain occurred only in 3.2% children with IgA nephropathy. The renal pathological investigation showed global sclerosis in 35.5% of IgA nephropathy and 3.1% of HSPN, mesangial sclerosis in 41.9% of IgA nephropathy and 6.3% of HSPN, but endothelial proliferation in 65.6% of HSPN and 29% of IgA nephropathy. The differences were extremely significant (P < 0.01). Thin basement membrane nephropathy were only found in 6.5% children with IgA nephropathy, but in none with HSPN. The electronic dense deposits in HSPN were sparse, loose and widely spread in glomerular mesangium, subendothelial area and even intra basement membrane. While the deposits were dense, lumpy and mostly limited in mesangium and paramesangium in IgA nephropathy. IgG was found in glomerular immune deposits in 71.9% of HSPN, but only 19.4% of IgA nephropathy. No IgG deposit was observed in 81.6% of IgA nephropathy, among them most showed IgA and IgM and/or C(3) deposit. Predominant IgG deposits were found in 12.5% of HSPN with relatively weak IgA deposit, moreover 6.3% of HSPN showed linear IgG deposits in glomerular capillary wall, which couldn't be found in IgA nephropathy. The follow-up data of average 20 months showed complete remission in 72.5% of HSPN and 19.4% in IgA nephropathy after 34 months follow-up. Moreover, 64.5% of IgA nephropathy had consistent hematuria and proteinuria, 16.1% had active nephritides, the difference was significant (P < 0.05).

CONCLUSIONSignificant clinico-pathological differences were found between HSPN and IgA nephropathy, which does not support the one disease entity hypothesis. HSPN and IgA nephropathy are probably two diseases with similar immune abnormalities.

OBJECTIVETo explore the molecular mechanism of APL cell resistance to ATRA.

METHODSThe ATRA sensitive and resistant APL cell lines, NB4 and NB4-R1, were used as in vitro models. The effects of specific inhibitors and activators of adenylate cyclase (AC) and phosphodiesterase (PDE) on ATRA-induced differentiation was evaluated by cell morphology, cell surface antigen expression and nitroblue-tetrazolium (NBT) reduction assays.

RESULTSSQ22536, a specific antagonist of AC, could dramatically block ATRA-induced NB4 cell differentiation. When ATRA + SQ22536 group compared with ATRA group, the positivity of CD11b decreased from (95.9 +/- 2.5)% to (60.3 +/- 7.1)%, while the A(540) in NBT reduction assay decreased from 0.585 +/- 0.092 to 0.170 +/- 0.028 (P < 0.05). Forskolin, an agonist of AC, could overcome the resistance of NB4-R1 cells to ATRA. When ATRA + forskolin group compared with ATRA group, the positivity of CD11b increased from (34.3 +/- 5.3)% to (94.6 +/- 2.4)%, while the A(540) in NBT reduction assay increased from 0.110 +/- 0.028 to 0.395 +/- 0.049 (P < 0.05). In contrast, the specific antagonist and agonist of PDE, 3-isobutyl-1-methylxanthine (IBMX) and calmodulin, exerted little impact on ATRA treatment.

CONCLUSIONSThe defaults in the initiation of AC activation may contribute to the resistance to ATRA in some APL cells.

AIMTo know the effect of cysteamine (CS) on the plasma levels of somatostatin (SS) and some metabolic hormones in adult geese.

METHODSFourteen adult crossbred geese (Chuan white x Tai lake) fitted with chronic wing vein cannulas were used in this study to evaluate the effect of CS on SS, TSH, T3 and T4 levels. The experiment was consisted of control and treated phase. The diet was added CS at dosage of 100 mg/kg bw on the first day of the treated phase. The blood samples were collected from the cannulas and analyzed by radioimmunoassay.

RESULTSThe plasma SS concentration was (1.87 +/- 0.10) microg/L in control phase. Whereas SS concentrations on day 1, 3, 5, 7 of treated phase were decreased markedly (P < 0.05 or P < 0.01). Thereafter it was rose on the seventh day, however it was still lower than that of control. The thyroid stimulating hormone (TSH) content (2.45 +/- 0.31 mIU/L) was significantly decreased by 21.63% (P < 0.01) on day 1, and 18.37% (P > 0.05) on day 3 and day 5. Comparing with control phase (5.41 +/- 0.98 microg/L), T4 contents were elevated by 60.26% (P < 0.01), 43.25% (P < 0.01), 37.15% (P < 0.01) and 16. 82% (P < 0.01) respectively on day 1, 3, 5, 7. T3 level was (1.05 +/- 0.06) microg/L in control phase, whereas the levels was significantly increased by 36.19% (P < 0.01) on day 3. Also, the insulin concentration was higher than that of control (4.43 +/- 0.41 mU/ L) by 18.28% (P < 0.05) on the day 5.

CONCLUSIONThese results indicate that CS can decrease the plasma SS and TSH levels, whereas increase the levels of T4, T3 and insulin, therefore change metabolism, improve the nutrition transform and accelerate the growth in geese.

Metabolomics, a branch of systems biology, has gained extensive attention and profound achievements in the plant. Although plant metabolomics is to be explored, it has been one of the most effective methods to study the physiological and biochemical process and gene modification in pattern plants. We herein summarized the concept, development, and application of metabolomics and prospected the potentials in the metabolite profiling for plant. Metabolomics provides an omics' methodology to elucidate the whole biological process, identify and quantify the complex components in the plant. A number of metabolites present in the plant are active components of traditional Chinese medicine, and these bioactive components are influenced by the multi-factors such as environment, species, and processing methods etc. Therefore, it is of great importance to analyze a wide spectrum of compositions with diverse chemical characteristics and varied concentration, which is the foundation to quality control, allowing the elucidation of the pharmacological effectiveness, and further exploiting of traditional Chinese medicine.

OBJECTIVETo study the effect of Colquhounia root tablet (CRT) in treating childhood Henoch-Schonlein purpura nephritis (HSPN) and compared with tripterygium wilfordii multiglycoside tablet (TWMGT).

METHODSEighty-two children with HSPN were divided into the CRT group and the control group. To patients of nephritic type, treatment with CRT and TWMGT was applied separately, but to those of nephrotic type, the treatment was given together with prednisone. Therapeutic effect and changes of related indexes, including urinary protein, retinal-binding protein (RBP), N-acetyl-beta-glucosaminidase (NAG), were observed after patients received treatment for 6 months.

RESULTSThe complete remission (CR) rate and partial remission (PR) rate in patients of nephritic type in the treated group was 58.8% and 41.2% respectively, while those in the control group was 20.8% and 66.7% respectively, and the ineffective rate being 12.5%. Comparison of the therapeutic effect between the two groups showed significant difference (P < 0.05). Although the CR rate in patients of nephrotic type in the treated group was higher than that in the control group, the difference was insignificant (P > 0.05). The urinary levels of protein, RBP and NAG lowered in both groups, but level of urinary protein in the treated group of nephritic type after 6 months of treatment was significantly lower than that in the control group (P < 0.05).

CONCLUSIONCRT shows obvious effect in improving childhood HSPN of nephritic type, nephrotic type and attenuating the tubulointerstitial lesions, compared with TWMGT, CRT is more effective in lowering proteinuria and better in total effective rate.
