Objective:To analyze the relationship between hepatitis B virus(HBV)gene mutation at 1896 in precore region with genotype and replication of HBV and the liver function of patients.Methods:HBV precore 1896 site mutation,the genotype of HBV and serum content of HBV DNA were determined by PCR in 60 patients positive of HBV DNA.Chemiluminescence miacropaticle immunoassay(CMIA)was used for detection of serum HBeAg and HBeAb.Liver function parameters were ob- tained by routine biochemistry method.Results:The alanine aminotransferase(ALT)level in HBV with 1896 site mutation was significantly higher than that in the wildtype virus.Site mutation at 1896 had no correlation with HBeAg,HBV genotype and HBV DNA content.HBV DNA content in patient with genotype C was significantly higher than that with genotype B(P

Objective To investigate and assess the clinical effect of treatment of children′s fractures at distal radial or radial-ulna through incision and Kirschner wire′s interior fixation without coursing epiphysis.Methods The treatment of children′s fractures at distal radial or radial-ulna in our hospital between 1996 and 2005 were reviewed,91 cases via Kirsehner-wire′s internal fixation were dealt.According to the way of placing Kirschner wire,the patients were divided into 2 groups.Group A of 53 cases eschewing epiphysis and passed bone-cortex.Group B of 38 cases got intramedullary fixation and passed epiphysis for 38 cases.After 6-100 months′ follow-up investigation,the 2 groups were comporred by analyzing statistics and the number of cases which involved repeatedly setting of Kirschner wire during operation,anatomical restoration,replacement,Kirschner-wire moving,infection,wrist′s dysfunction and bridge between the epiphysis.Results The fractures in both groups were recovering well.Besides,both were at the low rate of repeated replacement,Kirschner wire moving and infection.However,there were significant differences on repeated setting of Kirschner wire during operation,wrist′s dysfunction and bridge between the epiphysis,of which group B were higher than those in group A.Conclusions While the children′s fractures at distal radial or radial-ulna will be reduced by incision and fixing with Kirschner wire,the way of eschewing epiphyses and passing bone-cortex is better because it accords with anatomic character of children.It can not only fix reliably and bring satisfying clinical treatment effect,but also cause little complication.Thus,it is superior to the way of intramedullary fixation and passed epihysis.

AIM: To investigate the mechanism of proliferation effect induced by (R,R)-XY-10 and (S,S)-XY-10 on retinal pigmented epithelial cells(ARPE-19).METHODS: Human retinal pigmented epithelial cells(ARPE-19) and human umbilical vein endothelial cells (HUVECs) were used to investigate the effect of (R,R)-XY-10 and (S,S)-XY-10 on cell growth,and their mechanisms of proliferative action by using ERK、 AKT、PI3K、Protein kinase C (PKC)and Nitric oxide synthase (NOS) inhibitors.RESULTS: (R,R)-XY-10 and (S,S)-XY-10 dose-dependently increased ARPE-19 cell proliferation,but not on HUVECs. When treated with proliferative inhibitors,H7(5μmol/L)、hypericin(20μmol/L)、PD98059(2μmol/L)、LY294002(50μmol/L)、SH-5 (10μmol/L) and L-NAME (100μmol/L),the proliferative effect was reduced by H7、hypericin、PD98059 and LY294002,but not by SH-5 and L-NAME.CONCLUSION: (R,R)-XY-10 and (S,S)-XY-10 can induce cell proliferation through MAPK and PI3K dependent pathway.

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.

Traditional non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 selective inhibitors are among the most widely used drugs. However, their significant side effects in gastrointestinal and cardiovascular systems limited the use of these drugs. Recently, research and development of NO-donating NSAIDs (NO-NSAIDs) have become one of the most important strategies to reduce these side effects. NO-NSAIDs may exert a broad range of positive effects in terms of NO-mediated gastrointestinal and cardiovascular safety as well as comparable or increased anti-inflammatory, analgesic properties relative to NSAIDs. This review briefly deals with chemistry of NO-NSAIDs, more details are focused on biological significance, mechanism of action, and therapeutic potential of this novel class of drugs.

Objective To investigate the application of SIEMENS Ysio DR amplification in the radiation dose reduction. Methods Totally 160 patients with similar heights and body shapes were divided equally into A,B,C and D groups,and then underwent radiological examinations with SIEMENS Ysio DR from September 2014 to May 2016.A and B groups went through right hand AP oblique examination with the same kV while different mAs, and C and D groups had chest posteroanterior examination with different kV and the same mAs. Image quality was regulated with the amplification coefficient, and then evaluated with double-blind method by two senior radiologists.Statistical analysis was executed over the values of mAs in A and B groups and those of kV in C and D groups. Results A group had the mAs value being(2.26 ±0.16)mAs, which was significantly different from that of B group [(4.05±0.19)mAs] (P<0.05);while C group had kV value being (104.79±6.39)kV, which was statistically different from that of D group [(83.48±3.67)kV] (P<0.05). Satisfactory image were obtained by regulation with amplication coefficient.There was no obvious difference between the image quality in either A and B groups or C and D groups(P>0.05).Based on the principle that low mAs resulted in low radiation dose and high kV lead to low effective dose,A group had the radiation dose lower than those of B group,and C group had the effective dose lower than those of D group. Conclusion SIEMENS Ysio DR has the photographing parameters regulated according to different sites and the amplification coefficient for enhancing image quality, which decreases X-ray radiation dose and effective dosage with the diagnosis results unaffected.

OBJECTIVETo explore the changes of different brain metabolites during hepatolenticular degeneration using diffusion weighted magnetic resonance imaging (DWI) and magnetic resonance spectroscopy (MRS) in patients with hepatolenticular degeneration and study the correlation of apparent diffusion coefficient(ADC) values and MRS with the different pathological changes.

METHODSTotally 53 patients with hepatolenticular degeneration were enrolled in this study and divided into DWI high-signal group (n=31) and DWI low-signal group (n=22). Magnetic resonance scan, DWI, and spectroscopy were performed before treatment and 4 months after treatment. The changes of ADC value, N-acetyl aspartate (NAA)/creatine (Cr) ratio, and choline (Cho)/Cr ratio were recorded.

RESULTSBefore treatment, the NAA/Cr ratio was significantly higher in the DWI high-signal group than in DWI low-signal group (P=0.002), whereas ADC value and NAA/Cr ratio were significantly lower (P=0.004, P=0.014, respectively). After treatment, the NAA/Cr ratio was still significantly higher in the DWI high-signal group (P=0.036), while the differences of ADC value and Cho/Cr ratio showed no statistical deference (P>0.05). In the DWI high-signal group, the ADC value and NAA/Cr ratio were significantly elevated after treatment (P=0.006, P=0.008), whereas the Cho/Cr ratio showed no significant change (P>0.05). In the DWI low signal group, NAA/Cr ratio was significantly increased after treatment (P=0.015), while the ADC value and Cho/Cr ratio showed no significant change (P>0.05).

CONCLUSIONSDWI combined MRS imaging can be used to evaluate the microscopic structure and metabolic changes during copper deposition and thus, compared with the conventional magnetic resonance imaging provide more information on metabolism. Therefore, they can be useful tools in the early diagnosis and efficacy evaluation of hepatolenticular degeneration.
