Objective: To investigate the curative effect of low-frequency therapeutic instrument of hepatopathy combined with Reduning injection in clinical treatment for patients with scarlet fever and hepatitis injury. Methods: 94 patients with scarlet fever and hepatitis injury were divided into observation group (47 cases) and control group (47cases). Patients of control group received the therapy of Reduning injection combined with tablet of adefovir dipivoxil, while the patients of observation group received the therapy of therapeutic instrument of hepatopathy combined with the therapy of control group. The changes of curative effect, indicator of hepatic fibrosis and response rate between two groups were observed. Results: The total effective rate of the observation group (95.7%) was significantly higher than that of control group (70.2%) (x2=7.283, P<0.05). In observation group, the hepatic fibrosis hyaluronic acid, III type procollagen, IV type collagen and laminin of post-treatment were significant improvement than that of pre-treatment (t=3.42, t=2.83, t=2.74, t=2.52, P<0.05). While in control groups, only the laminin of post-treatment was significant improvement than that of pre-treatment (t=2.15, P<0.05). After treatment, CR, VR, BR and HBeAg of observation group were significant higher than that of control group (x2=5.235, x2=5.623, x2=4.993, x2=6.823, P<0.05). Conclusion: The combination of low-frequency treatment of hepatopathy and Reduning injuection for the treatment of patients with scarlet fever and hepatic injury has significant effect, and it can effectively enhance the conversion rate of HBeAg, and improve liver function of patients. Therefore, it is worthy to be further promoteed in the clinical application.

ObjectiveTo detect glucose-6-phosphate isomerase (GPI) in knee joint synovial fluid of active rheumatoid arthritis (RA) and explore the correlation between GPI and anti-cyclic citrulline peptide antibody (anti-CCP).MethodsGPI and anti-CCP in the synovial fluid were measured by enzyme linked immunosorbent assay(ELISA) from 22 patients with active RA and 37 patients with active osteoarthritis (OA).Student's t-test was used for intergroup comparison and Spearman's analysis was used for correlation analysis.ResultsThe level of GPI and anti-CCP in the synovial of active RA [ (9.6±8.4) μg/ml,( 14.61 ±18.64) U/ml] was significantly higher than that of active OA[ (0.9±1.8) μg/ml,(1.42±0.09) U/ml)].There was positive correlation between GPI and anti-CCP (r=0.447,P=0.037).ConclusionHigh expression of GPI is shown in active RA synovial fluid.It is suggested that GPI as an antigen that may participate in chronic synovitis,bone destruction and joint malformation.Both GPI and anti-CCP may be the laboratory markers for the diagnosis of RA.

Objective To determine the efficiency of microwave heating of the conjunctival sac flushing liquid combined with disposible blood transfusion device to prepare for laser-assisted in situ keratomileusis (LASIK).Methods A total of 150 healthy myopia patients undergoing LASIK in Myopia Treatment Center of our hospital from February to August 2013 were divided into two groups randomly according to operation date,75 patients in each group.The observation group used a microwave oven to heat the flushing liquid connected with a disposable blood transfusion device.The control group used a hot water bath to heat the flushing liquid,which was then connected to a disposable infusion device.The heated liquid by both methods was applied to conjunctival sac flushing before LASIK.The time required for liquid heating was recorded and the outcome of the conjunctival sac flushing was compared between the two groups.Results The time required by the observation group and the control group of heating flushing fluid from 5,10,15,20,25 and 30 ℃ to (36.0±1.0) ℃ was 124,104,84,64,44,24 s and 372,312,252,192,132,72 s,respectively.The conjunctival sac flushing effect comparison between the observation group and the control group was as follows:in four indicators such as the operation cooperation,conjunctiva congestion,spasm of eyelid,eye pain,there was no significant difference between two groups; for tear fat deposition,there was significant difference between two groups (4 cases vs.15 cases,x2=7.292,P ＜ 0.01).Conclusions Microwave heating of the conjunctival sac flushing liquid connected with a disposable blood transfusion device is efficient,safe and easy to operate.Therefore,it gains approvement and high opinion of medical workers and is worth being popularized in clinic.

Objective To detect the expression of c-met (hepatocyte growth factor receptor), e2f-1 (transcription factor) and Ki-67 in tissues of gastric cancer, explore the relationship among them, and investigate their correlationship with clinicopathological characteristics and prognosis. Methods The tissue samples of gastric cancer from 86 patients with radical resection were subjected to immunohistochemical staining, and the expression of c-met, e2f-1 and Ki-67 was detected. The relationship between the clinicopathological characteristics and the expression of c-met, e2f-1 and Ki-67, and that among the expression of c-met, e2f-1 and Ki-67 were explored by univariate and multivariate data analysis. And the relationship between prognosis and expression of c-met, e2f-1 and Ki-67 was analysed by Log rank test. Results c-met, e2f-1 and Ki-67 were widely expressed in tissues of gastric cancer. The higher expression of c-met was associated with higher expression of Ki-67, shorter survival time, upper tumor location, higher lymph node metastasis rate, higher N stage and TNM stage (P<0.05), and the lower expression of e2f-1 was associated with larger tumor diameter, higher TNM stage, deeper invasion, higher lymph node metastasis rate and higher N stage (P<0.05). The multivariate analysis revealed that depth of invasion, N stage, TNM stage and expression of Ki-67 were independent factors for positive expression of c-met, and age and survival time were independent factors for positive expression of e2f-1. Log rank test demonstrated that the factors related to survival included expression of c-met, e2f-1 and Ki-67, N stage, tumor diameter, tumor location, lymph node metastasis rate, depth of invasion and TNM stage. Conclusion c-met is an indicator for malignant behavior and poorer prognosis of gastric cancer. There is a higher expression of e2f-1 in early gastric cancer, while advanced gastric cancer may be associated with a lower expression of e2f-1.

Objective To determine the polymorphism in CXC chemokine SDF-1α transcript and its effects on HIV infection.Methods Three groups of study subjects lived in Hang Kong were recruited:278 HIV-heahhy donors of Chinese origin.49 HIV+Caucasians and 13 Chinese with high risk behavior to HIV but kept uninfected.Genomic DNA and RNA were extracted from eripheral blood mononucleal cell. The PCR and RT-PCR reaction were set up accordingly.Sequence of the SDF-1α promoter,the open reading frame(ORF)and the 3'untranslate region(3'UTR)were analyzed.Two steps PCR reaction using two reverseprimers with mismatched nucleic acid were employed to screen the frequency of a novel mutation. Results equencing analysis from 100 subjects indicated that non mutation happened in tlle promoter and ORF of SDF-1α.A novel mutation Was detected from 3'UTR of SDF-1α.It is a "GA" insertion in "G" rich region near the stop code of SDF-1α.The mutation Was named as SDF-1-3’GA+and submitted to GenBank (AY874118).The mutation happened in three roups.with allele frequency of 15.1% in the healthy Chinese.of 30.7% in the high risk Chinese group.Conclusions our results confirm that SDF-1 genes arerelatively conserved.None noteworthy mutation is identified in the promoter and ORF regions of SDF-1α However.a novel mutation is identified from the 3'UTR of SDF-1α. It would be worthwhile to etermine effect of the novel mutation on HIV infection.

Objective To investigate the role of lysyl oxidase (LOX) in synovitis and cartilage destruction by comparing the expression of LOX in synovial fluid and synovium of active rheumatoid arthritis (RA) and active osteoarthritis (OA).Methods LOX in the synovium was detected by immunohistochemistry from 14 patients with active RA,24 patients with active OA and 20 patients with knee injury (the control group).LOX in the synovial fluid was measured by enzyme linked immunosorbent assay (ELISA) from 14 patients with active RA and 24 patients with active OA.T-test was used for statistical analysis.Results The level of LOX expression in active RA synovium (0.012±0.007) was similar to that in active OA synovium (0.013±0.011,P＞0.05).But the expression of LOX in synovium of active RA and active OA was significantly higher than that in synovium of the control group (0.003±0.004,P＜0.01).The amount of LOX in the synovial fluid of active RA [(1.9±1.4) μg/ml] was significantly higher than that of active OA [(1.0±0.4) μg/ml,P＜0.05].Conclusion High expression of LOX in the synovial fluid and synovium of active RA and active OA suggest that LOX may be involved in chronic synovitis and cartilage destruction,and may be related with the extent of synovitis and cartilage destruction.
