Objective To study apoptosis and antigen presentation changes of monocytes in HBV-related acute-on-chronic liver failure (ACLF) patients under immune dysfunction state.Methods Peripheral blood samples of 26 HBV-related ACLF patients (ACLF group),20 active chronic hepatitis B patients (CHB group) and 18 healthy individuals (control group) were collected.The changes of apoptosis and proliferation (Ki67) in monocytes and the expression of surface markers including human leukocyte antigen (HLA)-DR and B7 molecules (CD86) of monocytes were analyzed by flow cytometry. Results The percentage of Annexin V expressed monocytes of ACLF group (64％) was significantly higher than that of CHB group (28％) and control group (20％),and the difference was statistically significant (x2 value was 11.75 and 27.23 ; both P＜0.01),which indicated that monocytes apoptosis increased.The Ki67 expression in monocytes of ACLF group was lower than that of CHB group and control group,and the difference was statistically significant (x2 value was 4.71 and 4.83; both P＜ 0.05),which indicated that activated monocytes reduced. The mean fluorescence intensity (MFI) of HLA-DR and CD86 of monocytes in ACLF group was 22.85 and 11.63,which was significantly lower than that of CHB group and control group,indicating the antigen presentation ability of monocytes injured. The percentage of Annexin Ⅴ positive monocytes in survivals (62 ％ ) was significantly higher than that of dead patients (46 ％ ) in ACLF group.Conclusion In HBV-related ACLF patients under immune dysfunction state,the apoptosis of peripheral blood monocytes increased,and the quantity of activated cells reduced,resulting in the decline of the antigen presentation ability of monocytes.

Objective To explore the efficacy of Fushe Jiedu Decoction combined with red light on viper bites injury limb swelling and the effects on the inflammatory cytokines. Methods Totally 90 patients were divided into control group and experimental group by using random number table method, with 45 cases in each group. The wounds of the control group were sterilized and given anti-snake venom serum, antibiotics, and tetanus immunoglobulin and supplemented with energy to correct water and electrolyte disturbances. The experimental group was treated with Fushe Jiedu Decoction based on the treatment of control group,150 mL each time,orally,twice a day; Red light was applied at the site of the most obvious swelling of the injured limb, 20 minutes each time, twice a day. The treatment lasted for 6 d. The swelling of injured limbs, serum C-reactive protein (CRP), 5-hydroxytryptamine (5-HT), histamine, tumor necrosis factor-α (TNF-α), interleukin (IL)-6 levels before and after treatment in the two groups were observed. Results Compared with before treatment, the swelling of the limbs disappeared significantly in the experimental group at 3 d and 6 d and in the control group at 6 d, with statistical significance (P<0.01). Compared with the control group at the same time point, the swelling of the limbs in the treatment group was significantly better than that in the control group at 3 d and 6 d, with statistical significance (P<0.01). Compared with before treatment, the levels of CRP, 5-HT, TNF-α, and IL-6 were significantly lower in the two groups, with statistical significance (P<0.05). After treatment, CRP, 5-HT and histamine in the experimental group were significantly better than that in the control group(P<0.05).Conclusion Fushe Jiedu Decoction combined with red light has good efficacy for viper bites injury limb swelling, which can reduce inflammatory cytokines levels of patients.

OBJECTIVETo evaluate the strength of pedicle screw fixation with bone cement in human cadaveric lumbar vertebral bodies by using biomechanical test.

METHODSTwenty-four fresh frozen cadaveric lumbar vertebral bodies were randomly divided into 3 groups, which each group had 8 bodies. The bodies in the first group were drilled only. The bodies in the second group were drilled with tap. The bodies in the third group were drilled and the holes were enlarged by borer. Each vertebral body was drilled in both right and left sides, which one side served as control with the pedicle screws fixation only and another side served as testing side with the pedicle screw fixation with bone cement. The pullout strength was tested on both sides by using borer.

RESULTThere was significant difference of manifestation of pull-strength between the control side and the testing side in all groups (P < 0.001). For the manifestation of pull-strength of testing side in different groups, which had pedicle screw fixation with bone cement, there was no significant difference between the second group and third group, however, the difference between the first group and the second group and between the first group and third group were significant.

CONCLUSIONThe pedicle screws with bone cements could significantly enhance the strength of fixation in cadaveric lumbar compared with pedicle screws only.

OBJECTIVETo study changes in the radiographic appearance during weight-bearing and non-weigh-bearing in hallux valgus, and to analyse the correlation between the elasticity of plantar soft tissue of hallux valgus and the pain under the metatarsal head.

METHODSFrom May 2012 to October 2012, 240 feet of 120 patients with hallux valgus were enrolled in the study. The degrees of the pian under the metatarsal head of all the patients were observed. AP and lateral X-ray films of feet were taken on the condition of weight-bearing and non-weight-bearing. So the hallux valgus angle (HVA), the inter-metatarsal angle between the first and second metatarsals (IM1-2), the inter-metatarsal angle between the first and fifth metatarsals (IM1-5), top angle of the medial longitudinal arch (TAOTMLA),and anterior angle of the medial longitudinal arch (AAOTMLA) were measured on the X-ray films. The differences of HVA, IM1-2, IM1-5, TAOTMLA and AAOTMLA between two groups were compared, and the correlation between the changes of IM1-2, IM 1-5, TAOTMLA, AAOTMLA and the degree of the pain under the metatarsal head were analysed.

RESULTSOne hundred and forty-eight feet had the pain under the metatarsal head. The IM1-2, IM1-5 and TAOTMLA increased on weight-bearing position compared with those on non-weight-bearing position, but the HVA and AAOTMLA decreased on weight-bearing position compared with those on non-weight-bearing position. There was a moderate relationship between the changes of IM 1-2,IM1-5 and the degree of the hallux valgus deformity, as well as the relationship between the different of IM1-5 and the degree of the pian under the metatarsal head.

CONCLUSIONThe degree of the collapse of the arch of foot with hallux valgus becomes serious with its deformity increasing. The pain under the metatarsal head of hallux valgus increases with the increased changes of IM 1-2,IM 1-5 and TAOTMLA. Analysis of the X-ray observation indexes of hallux valgus on weight-bearing position and non-weight-bearing position has important significance in evaluating the degree of the collapse of the arch of foot with hallux valgus,preventing and curing the the pain under the metatarsal head.

OBJECTIVETo explore the functional effects of MAPK pathway in the pathogenesis of human osteosarcoma.

METHODSGene microarray (Human Genome U133A, Affymetrix) was used to screen the differential expression of genes involved in MAPK pathway between osteosarcoma cell lines and 3 osteoblastic cell lines. KEGG metabolic pathway analysis was performed among significantly increased or decreased genes using the MATLAB software. Immunohistochemical technique was used to detect the expressions of ERK1/2, JNK and p38 proteins among 48 osteosarcoma and benign 24 osteoblastic tumor samples.

RESULTSUsing an entrance limit of > or = 2.0, 18 differentially expressed MAPK pathway-related genes were selected (10 up-regulated, 8 down-regulated) to mapped to the MAPK pathway of KEGG which are all important node genes. The positive rates of ERK1/2, JNK and p38 proteins were 83.3% (40/48), 72.9% (35/48) and 85.4% (41/48) in osteosarcomas,and 12.5% (3/24), 8.3% (2/24) and 16.7% (4/24) in the control group, respectively. The positive rates and expression intensities were statistically different between the 2 groups (P<0.01).

CONCLUSIONMAPK pathway plays an important role in the pathogenesis of osteosarcoma. ERK, JNK and p38 form an intercoordinating network and regulate the cell proliferation, differentiation, apoptosis, invasion and migration in osteosarcoma.

OBJECTIVETo investigate the effects of hydroquinone (HQ) on expression of Polymerase eta (Pol eta) and DNA damage in human hepatic cells (L-02), and to explore the role and possible mechanism of Pol eta involved in the process of DNA damage-tolerance.

METHODSAfter L-02 hepatic cells were exposed to HQ with various concentrations (0, 5, 10, 20, 40, 80 and 160 micromol/L) for 24 h, cell survival rate was detected by MTT assay; DNA impairment was detected by single cell gel electrophoresis (SCGE); Real-time fluorescent quantitative PCR and Western blotting methods were used to measure the expression of Pol eta at the mRNA and protein level in L-02 hepatic cells exposed to HQ with various concentrations (0, 5, 10, 20, 40, 80 and 160 micromol/L).

RESULTSMTT assay showed that HQ with concentrations from 0 to 80 micromol/L had little effect on the survival rate of L-02 (P>0.05); whereas the survival rate of the group of 160 micromol/Lwas significantly higher than that of the control (P<0.01) after being treated with HQ for 24 h; the higher dose of HQ presented, the more degrees of DNA damage were produced. It was found that HQ in a low concentration (1-80 micromol/L) could induce the expression of Pol eta which was in proportion to the increasements of HQ concentration; the expression levels of mRNA and protein were reached to the maximum when treated with 80 micromol/L; the expression of Pol eta decreased (the relative quantity values were 2.32 +/- 0.16 and 1.20 respectively) once the concentration of HQ exceeded 160 micromol/L as compared with the group of 80 micromol/L, but it was higher than that of the control.

CONCLUSIONThis study suggested that Pol eta might involve in the process of DNA damage-tolerance induced by HQ in the hepatic cells.

OBJECTIVEThe aim of this study was to evaluate the effects of XRCCl gene polymorphisms and its haplotype on the susceptibility of pancreatic carcinoma.

METHODSPeripheral blood DNA was extracted from 210 pancreatic carcinoma patients and 213 control subjects. SNaPshot technique was used for genotyping seven SNP sites of the XRCCl gene (rs3213403, rs25487, rs1799782, rs731420, rs1001581, rs12611088, and rs3213282). Logistic regression model was performed to analyze the relationship of different genotypes or haplotype and the susceptibility of pancreatic carcinoma.

RESULTSThe frequency for allele A at site rs25487 in the case group was significantly higher than that in the control group (P < 0.05). The frequency of GG, GA and AA genotype between the case group and control group had statistically significant differences (P < 0.05). Compared with GG genotype, the risk of pancreatic carcinoma in the subjects carrying mutated allele A (GA+AA) was increased by 0.648 times (P < 0.05). Among them the pancreatic carcinoma risk of individuals carrying A allele was increased by 0.552 times compared with the individuals carrying G allele. The frequency of allele and genotype at site rs1799782 in the case group and control group had a significant difference (P < 0.05). Compared with the CC genotype, the risk of pancreatic carcinoma in the subjects carrying mutated allele T (CT+TT) was increased by 0.683 times. Among them the pancreatic carcinoma risk of individuals carrying T allele was increased by 0.549 times compared with the individuals carrying C allele. Significant differences were observed in linkage disequilibrium between any two of the seven SNPs (P < 0.05), the frequency of H4-AGCCCGC, H6-GGCCCGG or H7-AGCCTAG haplotypes was significantly lower in the case group than that in the control group (P < 0.05).

CONCLUSIONSThe single nucleotide polymorphisms of rs25487 and rs1799782 for XRCC1 gene may be correlated with the occurrence of pancreatic carcinoma. The haplotypes of H4-AGCCCGC, H6-GGCCCGG and H7-AGCCTAG might be a potential genetic protective factor for the occurrence of pancreatic carcinoma.
