[Objective] China is one of high hepatitis B virus (HBV)-epidemic areas. The role of HBV and nonHodgkin lymphoma (NHL) has also recently been investigated. There is significantly higher prevalence rate of HBV infection among patients with NHL compared with other solid tumor and general population. HBV reactivation during chemotherapy is, however, a real concern. Several previous studies have reported increased risks of liver-related morbidity and mortality. The use of prophylactic anti-HBV drugs can effectively reduce the incidence and severity of hepatitis among HBV-infected patients who received chemotherapy for NHL.

Objective To observe the efficacy of percutaneous vertebroplasty (PVP) combined with zoledronic acid in treatment of spinal metastatic carcinoma.Methods Fifty cases of spinal metastatic carcinoma were divided into control group and treatment group by random digits table method with 25 cases each.The control group was given zoledronic acid 4 mg,intervals of 28 d intravenous drip 1 time.The treatment group was given PVP besides zoledronic acid.The visual analog scale score,activity ability score and analgesic usage score after treatment for 3 months were observed and compared.The quality of life was evaluated and the occurrence of relapse of fracture was also recorded.Results After treatment for 3 months,the visual analog scale score,activity ability score and analgesic usage score were (2.00 ± 0.17),(2.12 ± 1.38),(1.47 ± 0.10) scores in treatment group,and (7.84 ± 0.18),(3.21 ± 0.13),(3.30 ± 0.09) scores in control group,and there were significant differences between two groups (P ＜ 0.01 or ＜ 0.05).The occurrence of relapse of fracture was 2 cases (8％,2/25) in treatment group and 9 cases (36％,9/25) in control group,and there was significant difference between two groups (P ＜ 0.05).Conclusions PVP combined with zoledronic acid in treatment of spinal metastatic carcinoma has many advantages such as small incision,short surgery time and rapid relief from pain.It can obviously improve the quality of life,and it is worthy of spreading in the clinic.

The influence of temperature, chloride ions and sulfide ions on the anticorrosion behavior of 316L stainless steel in simulated cooling water was studied by electrochemical impedance spectroscopy and anodic polarization curves. The results show that the film resistance increases with the solution temperature but decreases after 8 days' immersion, which indicates that the film formed at higher temperature has inferior anticorrosion behavior; Chloride ions and sulfide ions have remarkable effects on the electrochemical property of 316L stainless steel in simulated cooling water and the pitting potential declines with the concentration of chloride ions; the passivation current has no obvious effect; the rise of the concentration of sulfide ions obviously increases the passivation current, but the pitting potential changes little, which indicates that the two types of ions may have different effects on destructing passive film of stainless steel. The critical concentration of chloride ions causing anodic potential curve's change in simulated cooling water is 250 mg/L for 316 L stainless. The effect of sulfide ions on the corrosion resistance behavior of stainless steel is increasing the passivation current density Ip. The addition of 6mg/L sulfide ions to the solution makes Ip of 316 L increase by 0.5 times.

ObjectiveTo investigate the effect of early induced finger function training on motor function and activities of daily living (ADL) of stroke patients.Methods60 stroke patients with hemiplegia were randomly divided into the early induced finger function training group (treatment group) and control group with 30 cases in each group. The patients of the control group were treated with routine rehabilitation; while those of the treatment group were added with training of early induced flexion and extension of fingers. All patients of two groups were assessed with Brunnstorm Scale, Fugl-Meyer Assessment, scores of Neurological Functional Deficit, and Modified Barthel Index before and 8～12 weeks after treatment.ResultsAfter treatment, upper limb motor function, hand function and fingers' fine function in the sick side of the patients in the treatment group improved significantly better than that in the control group ( P<0.05～0.01).ConclusionThe early induced finger function training can obviously improve the upper limb motor function and ADL of stroke patients.

This study aimed to explore the impact of depression caused by chronic unpredictable mild stress (CUMS) on in vivo activity of six kinds of CYP450 isoforms in rats. According to 'Katz' method, the model of CUMS was established. Tolbutamide, chlorzoxazone, theophylline, midazolam, omeprazole and dextromethorphan were chosen as probe substrates of CYP2C6, CYP2E1, CYP1A2, CYP3A2, CYP2D1 and CYP2D2 of rats. Plasma concentration of six kinds of CYP450 in control group and model group were determined by LC-MS/MS and computed pharmacokinetic parameters. Consequently, metabolism of theophylline and chlorzoxazone accelerated significantly (P < 0.01), but tolbutamide, dextromethorphan, omeprazole and midazolam had no significant difference. The present study proved that depression caused by CUMS had strong induction to CYP1A2 and medium induction to CYP2E1.

BACKGROUND: Nanotechnology has widely used in tissue engineered reconstruction in recent years. Most reports are concerning carbon nanomaterials in bone reparation, but the study of peripheral nerve regeneration is poorly understood.OBJECTIVE: To improve the physical, chemical and biological properties of chitosan/collagen composite nerve conduit with functionalized carbon nanotubes, in addition, to investigate the therapeutic effect of this novel material.DESIGN, TIME AND SETTING: The same body controlled experiment of animals was performed at the Tissue Engineering Laboratory and The Key Laboratory of Thin Film and Microfabrication Technology, Shanghai Jiao Tong University from February 2005 to November 2006.MATERIALS: The carbon nanotubes were mixed with 2% chitosan solution, coated on the die to prepare chitosan/collagen composite nerve conduit with functionalized carbon nanotubes. The chitosan/collagen tubes were served as controls.METHODS: A total of 80 male adult-rats were prepared a 4 mm accessory nerve defects models, and repaired by nerve conduit in the experimental material and control material groups. In the auto nerve grafts group, the removed nerve was connected to the broken end. In the blank control group, there was no other treatment except removing 2 mm nerves. The left sides were served as experimental sides and the right sides as within-subject controls.MAIN OUTCOME MEASURES: The repairing outcomes were measured by electrophysiological, myophysiological, and histological measurements.RESULTS: The accessory nerve defects were repaired in a rat model using carbon nanotubes in chitosan/collagen-based composite nerve conduit. As time passed after the surgery, good results of the electrophysiological, myophysiological and histological measurements were achieved, which were similar or superior to those of the nerve autografts.CONCLUSION: The carbon nanotubes in chitosan/collagen-based composite can be an ideal candidate for peripheral nerve regeneration.
