ObjectiveTo investigate the role of T-type calcium channel in the spinal neurotoxicity of intrathecal (IT) lidocaine in rats.MethodsForty-eight adult male SD rats in which IT catheter was successfully implanted,weighing 230-270 g,were randomly divided into 4 groups ( n =12 each):dimethyl sulfoxide (DMSO)group (group D),lidocaine group (group L),mibefradil + lidocaine group (group M),normal saline + lidocaine group (group N).Another 12 rats served as control group (group C).DMSO and 10％ lidocaine 20μl were injected intrathecally in groups D and L respectively.After mibefradil 200 μg/10μl and normal saline 10 μl were injected intrathecally in groups M and N respectively,10％ lidocaine 20 μl was injected intrathecally in the two groups.The mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured before IT injection and at 2,4,8 and 12 h and 1,2,3,4 and 5 d after IT injection (T0-9).Four rats were sacrificed at T6 in each group and their lumbar enlargements were removed for microscopic examination.ResultsCompared with group C,no significant change in MWT and TWL was found at each time point in group D,MWT was significantly increased at T1-8 and TWL was significantly prolonged at T1-7 in groups L and N,and MWT was significantly increased at T1-6 and TWL was significantly prolonged at T1-6 in group M ( P ＜ 0.05 ).Compared with groups L and N,MWT was significantly decreased at T1-4 and TWL was significantly shortened at T1-4 in group M ( P ＜ 0.05).Pathological injury was significantly reduced in group M as compared with groups L and N.ConclusionT-type calcium channel is involved in the spinal neurotoxicity of IT lidocaine in rats.

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.

[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 describe health service use and trend of treatment and rehabilitation rates among people with psychiatric disability from 2007 to 2013.Methods:Data collected by the 2006 Second China National Sample Survey and the 2007-2013 National Disability Monitoring Survey were utilized and analyzed.The 2006 National Sample Survey on Disabilities investigated 2 526 145 non-institutionalized representative civilians in 734 counties across mainland China.Psychiatric disability was diagnosed by clinical psychiatrists according to ICD-10 and WHO DAS Ⅱ criteria.The 2007 to 2013 National Disability Monitoring Survey selected 1 to 2 study sites among each of the 734 study counties that had been investigated by the Second China National Sample Survey.Information on living conditions,health service use,education and employment were recorded.Results:The data showed that treatment and rehabilitation rates for people with psychiatric disability had largely increased from 2007 to 2013 among adults aged 18 years or older,with the treatment and rehabilitation rates from 49.52％ and 21.8％ to 66.9％ and 58.7％ respectively,and the rates among those with 17 years or younger from 23.5％ to 43.9％.However,with regard to the effect of the treatment and rehabilitation services,a much larger proportion of people with psychiatric disability reported that the effect was soso instead of good or very good.In addition,among those who received rehabilitation service,most received day care or psychotherapy service,only less than 8％ participated work therapy,farming therapy or working skill trainings.Conclusion:The results suggest treatment and rehabilitation rates among people with psychiatric disability are largely increased from 2007 to 2013,while the quality of the service needs further attention.
