ABSTRACT
Objective To study the biological characteristics of, antibiotic resistance in and ger-micidal efficacy at different temperatures against Vibrio parahaemolyticus ( V. parahaemolyticus) strains isola-ted from different sources in order to provide reference for clinical treatment and prevention. Methods Stool samples from patients with diarrhea and small seafood product specimens from markets were collected and an-alyzed with biochemical identification method, serotyping analysis, drug susceptibility test and germicidal ef-ficacy test at different temperatures. Results There were 107 V. parahaemolyticus strains isolated from 1166 stool samples of patients with foodborne diarrhea with a positive rate of 9. 18％ and 42 from 72 seafood product samples with a positive rate of 58. 30％. V. parahaemolyticus strains isolated from the foodborne diar-rhea cases were divided into eight serogroups and among them, O3 and O4 were the predominant serogroups, accounting for 49. 53％ and 34. 58％, respectively. Most of the O antigens in small seafood products be-longed to serogroups of O4, O1 and O3, and four strains of O3 : K6 were isolated. Results of the drug sus-ceptibility test showed that both of the clinical isolates and marine product isolates were highly resistant to ampicillin and the drug resistance rates were 94. 39％ and 88. 10％, respectively. Antibiotic-sensitive strains to monocyclicβ-lactams, aminoglycosides, quinolones, carbapenems, tetracyclines and sulfonamides accounted for over 90. 00％ or even nearly 100. 00％. There were 17 (15. 89％) clinical strains and three (7. 14％) marine product isolates resistant to three or more kinds of antibiotics. At 80℃, the bactericidal rate for marine product isolates was 85. 71％ in 60 s and reached 100. 00％ in 90 s. At 90℃ and 100℃, these isolates could be completely killed in 40 s and 30 s. It took 120 s, 90 s and 50 s to kill clinical isolates at 80℃, 90℃ and 100℃, respectively. Conclusions This study systematically analyzed and compared the drug-resistant phenotypes of and the bactericidal efficacy at different temperatures on V. parahaemolyticus strains isolated from clinical samples and marine products. It would provide reference for preventing and con-trolling the spread of V. parahaemolyticus and hospital infection and for studying treatment strategies.

ABSTRACT
Objective To evaluate the therapeutic effect ofGuizhi-Fuling Pill combined with conventional western medicine therapy for diabetic peripheral neuropathy (DPN).Methods A total of 78 patients with DNP were randomly divided into treatment group (40 patients) and control group (38 patients).The patients in the control group were administrated with mecobalamin on the basis of conventional treatment. In addition to the therapy of control group,patients in treatment group were givenGuizhi-Fuling Pill. The patients in both groups were treated for 2 weeks.The level of homocysteine (Hcy) and sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity (MNCV) in both groups were measured. Toronto clinical scoring system (TCSS) was used to evaluate the curative effect.Results The total effect rate in the treatment group was significantly higher than that in the control group (95.0%vs. 76.3%;χ2=5.616,P=0.018). After treatment, the MNCV of common peroneal nerve (46.1 ± 6.3 m/svs.42.5 ± 5.5 m/s;t=2.734,P<0.01 ), MNCV of median nerve (49.8 ± 5.2 m/svs.46.3 ± 5.9 m/s;t=2.607,P<0.05 ), SNCV of common peroneal nerve (38.5 ± 4.6 m/s vs. 35.4 ± 4.3 m/s;t=3.105,P<0.05 ), SNCV of median nerve (45.3 ± 5.2 m/svs. 42.3 ± 4.8 m/s;t=2.627, P<0.05 ) in the treatment group were significantly increased than those in the control group. The integral of TCSS (5.3 ± 3.1vs. 7.2 ± 2.9;t=2.823,P<0.01) and the level of Hcy (13.3 ± 3.2 μmol/Lvs. 17.1 ± 3.4 μmol/L;t=5.178, P<0.05) were significantly lower in treatment group than those in control group (P<0.05).Conclusions The Guizhi-Fuling Pill combined with conventional western medicine therapy could improve MNCV and SNCV and reduce the level of Hcy and improve the clinical effect.
ABSTRACT
BACKGROUND:On the basis of modern design method and numerical simulation, studies can explore the action mechanisms of sand therapy in Uyghur medicine. OBJECTIVE:To explore a kind of non-homogeneous and isotropic biological bone finite element modeling method based on CT value, and to study the influence of sand therapy in Uyghur medicine on the mechanical properties of rabbits’ femur. METHODS:Eight adult New Zealand white rabbits were used to establish osteoarthritis models of right posterior femur with papain. These rabbits were divided into sand therapy group and control group. In the sand therapy group, after treatment with sand therapy in Uyghur medicine, rabbit femoral models were scanned with CT. The fault image data were imported into MIMICS software. 3D model of femur was generated. The meshing was done. The material properties were given. Three-point bending in the Ansys was simulated and solved.Simultaneously, the isolated three point bending tests were performed in al rabbit models. The corresponding deflection and the maximum stress values were obtained. Finaly, the results obtained from the three-dimensional finite element modeling method were compared with the results obtained from the experiments. RESULTS AND CONCLUSION:(1) The deflection and the maximum stress obtained by the three-point bending simulation analysis with the three-dimensional finite element model of the rabbits’ femur were wel correlated with the data obtained from the experiments. (2) These results indicate that the finite element modeling method is consistent with the structural and material properties of bone, which can be used to analyze the stress and deformation ofbones.

ABSTRACT
The present paper is aimed to study the effect of sand-therapy with Uyghur medicine on biomechanical properties and femoral bone volume of the femur of osteoarthritis (OA) rabbits at two different ages. In the experiments, we injected Papain through the joint space of right knees into the bodies of New Zealand rabbits (16 in the growing group, and 16 in the mature group), and established an OA model. The 16 rabbits in the mature group were divided randomly into 2 sub-groups: 8 in control group (no sand therapy), and 8 sand-therapy group. The 16 rabbits in the growing group were divided randomly into 2 groups as well: 8 in the control group (no sand therapy), and 8 in the sand-therapy group. We carried out CT scanning four times (1 day before, 13th, 27th and 41st days after the establishment of the model, respectively). After importing the CT data to MIMICS, the different volumes of each sclerotin were recorded and change of the percentage of each sclerotins in total femur bone volume were analyzed. Finally the rabbit femurs were given three-point bending test, the elastic load and the elastic deflection were obtained and the inertia of the section, the maximum bending stresses, the bending modulus of elasticity and the structural rigidity were calculated. The experimental results showed that (1) Compared with 1 day before and 13th day after establishment of model at maturity, the cancellous bone volume increased and cortical bone volume decreased (P < 0.05), but compared with those in the control group, the cancellous bone volume of femurs decrease and cortical bone volume increased under sand-therapy (P < 0.05). Compared with those in the control group, there were no significant changes in the deflection and cross-sectional moment of inertia in the sand-therapy group (P > 0.05), but the maximum bending normal stress, maximum load, elastic modulus, and structural stiffness (P < 0.05) in the sand therapy group were larger than those in the control group. The study showed that sand-therapy in Uyghur medicine has benign effect on bone volume of the OA rabbit femur in two ages and the mechanical properties of the OA rabbit femur at the two ages induced by sand-therapy in Uyghur medicine have been improved.

Objective To investigate the expression of interferon inducible protein-10 (IP-10) in peripheral blood mononuclear cells (PBMC) of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), and its correlation with disease severity.Methods Eighty patients with HBV-ACLF, 60 patients with chronic hepatitis B (CHB), and 25 healthy controls were enrolled from the Affiliated Hospital of Hubei University of Arts and Science during October 2013 and February 2015.IP-10 mRNA in PBMC was measured by real time quantitative PCR.Independent sample t test was used to analyze the difference in IP-10 mRNA expression between HBV-ACLF patients with model for end-stage liver disease (MELD) ＜ 30 and ≥30, and Pearson correlation test was performed to analyze the correlations of IP-10 mRNA expression with alanine aminotransferase (ALT), total bilirubin (TBil) and international normalized ratio (INR).Results The expressions of IP-10 mRNA in HBV-ACLF patients was 1.00 ± 0.19, which was higher than those in CHB patients and healthy controls (0.64 ± 0.08 and 0.41 ± 0.06, t =3.841 and 16.661, all P ＜ 0.01).The expression of IP-10 mRNA in HBV-ACLF patients with MELD ＜ 30 was 0.96 ±0.19, which was lower than that in patients with MELD ≥ 30 (1.14 ± 0.21, t =-2.283, P ＜0.05).Pearson correlation analysis showed that IP-10 mRNA level in HBV-ACLF patients was positively correlated with ALT, TBil and INR (r =0.697, 0.738 and 0.775, all P ＜ 0.01).Conclusion IP-10 mRNA is over-expressed in PBMC of patients with HBV-ACLF, and it is correlated with disease severity, which suggests that IP-10 may play an important role in the progression of liver failure.
