Objective To study the function, effect and mechanism of prevention of pressure sore formation with stimulation of the dorsal ramus of spinal nerve root by transcutaneous pulse using plateshape surface electrode. Methods According to the odd number and even number of admission date, 81 patients were divided into the control group (41 cases) and the observation group (40 cases). The control group received standard pressure sore prevention nursing according to Basic Nursing, the observation group received stimulation of the dorsal ramus of spinal nerve root by transcutaneous pulse using plate-shape surface electrode based upon routine nursing. Results 1 case caught grade Ⅰ pressure sere,1 case with grade Ⅱ pressure sere, and the incidence rate was 4.88% in the observation group, while in the control group, 5 cases caught grade Ⅰ pressure sore,4 cases with grade Ⅱ pressure sore, and the incidence rate was 22.50%. Conclusions Combination of routine prevention method with stimulation of the dorsal ramus of spinal nerve root by transcutancous pulse to prevent pressure sore formation can reduce the incidence rate of pressure sore in high risk population. This technique is easy, painless, noninvasive, and is a novel method for early prevention of pressure sore.

AIM: To evaluate acrylic resin bone cement in combination with percutaneous kyphoplasty to treat spinal metastatic tumor and reconstruct spinal stability. METHODS: Thirty-three cases with spinal metastatic tumor underwent percutaneous kyphoplasty in the Department of Spinal Surgery, Shenzhen People's Hospital between October 2006 and January 2008. All affected spines were complicated by destruction of bone or compression fracture. Under monitoring by G-arm X-ray machine, bilateral pedicle puncture was performed, followed by balloon expanding and acrylic resin bone cement injection in thoracic vertebra (3.6 mL) and lumbar vertebra (4.8 mL). All patients were followed up for 6 months to evaluate biocompatibility, vertebral height changes, pain degree pre-and post-surgery and movement ability. RESULTS: Of 49 affected vertebras in 33 cases, 43 were one-off successful, and 5 cases died of tumor metabasis. Finally, 43 vertebras were included in final analysis. The paired t-test showed the post-surgery anterior and posterior vertebral heights were significantly higher than pre-surgery [(2.6?0.6) cm, (2.2?0.6) cm; (2.9?0.7) cm, (2.6?0.6) cm; P

Homogenous fat extract was injected through the femoral vein to induce respiratory distress syndrome in 15 dogs. It was found that the changes of blood gases, chest x-ray films, and lung pathology of the dogs were similar to those of adult respiratory distress syndrome.The pathogenesis was extensive pulmonary fat embolism with complement activation and free radicals formation. Vitamin E was consumed during antiperoxidation. It is believed that this model serves better for the study of respiratory distress syndrome.

The therapeutic effects of prostaglandin E1 on respiratory distress syndrome induced with homogeneous fat extraction were observed in dogs.It was found that prostaglandin E1 could alleviate hypoxemia,reduce pulmonary capillary permeability,and attenuste pulmonary edema.The mechanism of the therapeutic efficiency of prostaglandin E1 on pulmonary damages is that prostaglandin E1 can inhibit the adherence of polymorphonuclear netttrophils and the genesis of oxygen free radicals,and protect the pneumocyte type Ⅱ.

0.05). VIP, however, could inhibit the Con A-induced proliferation of T-cells from control subjects more significantly than that from asthmatics (P0.05). The cAMP level in T-cells, however, increased more significantly in the control group than that in the asthmatic group after the treatment of VIP or NaF (P0.05). CONCLUSION: Inhibition effect of VIP on Con A-induced proliferation of T-cells was less in asthmatics than in control subjects, which may be related to insufficiency of Gs ? coupled VIP receptor on T-lymphocytes in asthmatics.

Objective To detect the levels of tumor necrosis factor (TNF)-a,interleukin (IL)-1β,IL-2,1L-6,IL-8,1L-10,IL-12 and interferon (IFN)-α in the serum and cerebrospinal fluid of the patients with epidemic encephalitis B,and to investigate the roles in pathogenesis of epidemic encephalitis B.Methods Approximately of 2 mL serum and 2 mL cerebrospinal fluid from 24 patients with epidemic encephalitis B during acute phase were collected,and 2 mL serum from 20 healthy controls were collected.The levels of eytokines in serum and cerebrospinal fluid were detected by enzyme linked immunosorbent assay (ELISA).Means of multi-sample were compared by analysis of variance and means of two-sample were compared by t test.Results The levels of TNF-α,IL-1β,IL-6,IL-8,IL-10 and IFN-α in eerebrospinal fluid were (24.5±6.6),(7.8±2.4),(16.0±5.7),(17.6±4.8),(130.2±33.6) and (45.2±10.8) ng/L,respectively,and in serum were (25.3±11.2),(7.1±3.2),(14.5±6.2),(16.0±6.5),(82.0±27.8) and (42.5±16.2) ng/L,respectively.The levels of TNF-α,IL-1β,IL-6,IL-8,IL-10 and IFN-α in serum and cerebrospinal fluid from patients with epidemic encephalitis B were all higher than those in serum of healthy controls [(12.7±7.9),(2.6±1.0),(6.2±2.2),(9.6±3.3),(71.4±12.8) and (30.0±14.0) ng/L;F value was 14.10,29.46,23.38,14.78,32.59,7.52;all P＜0.01];while the levels of IL-2 and IL-12 were not increased significantly.The levels of IL-1β,IL-6,IL-8,IL-10,IL-12 and IFN-α in cerebrospinal fluid were higher than those in serum,while the levels of TNF-± and IL-2 in cerebrospinal fluid were lower than those in serum.The levels of IL-6 and IL-8 in cerebrospinal fluid from patients with severe type of epidemic encephalitis B were (18.8±5.4) ng/L and (20.7±2.7) ng/L,and were higher than those with common type [(12.1±3.0) and (13.3±3.3) ng/L;t=3.50,t=5.96;P＜0.05],while the levels of IL-2 in serum and in cerebrospinal fluid from patients with severe type were lower than those with common type. Conclusions Oversecretions of TNF-α,IL-1β,IL-6,IL-8,IL-10 and IFN-a are involved in the inflammatory damage of epidemic encephalitis B,while under-secretions of IL 2 and ILl2 may be involved in cellular immune responses.

Objective Multidrug resistance-associated protein 1 (MRP1) has been reported with a close correlation with tumor multi-drug resistance. Real-time quantitative PCR (QRT-PCR) was performed to detect the MRP1 gene expression in childhood acute lymphoblastic leukemia (ALL) and its clinical signiifcance was analyzed. Methods Sixty-seven denovo ALL patients and 10 healthier children as bone marrow donor were studied. The chemotherapy was given according to CCLG-2008 protocol. SPSS software was employed to analyze the data and p-value below 0.05 was regarded as statistic signiifcance. Results MRP1 expression level showed a close correlation with ALL risk, the median of MRP1 expression was 4.28 (2.75~6.12), 5.62 (4.99~8.60) and 7.56 (3.66~11.13) for standard-risk group (SR), intermediate-risk group (IR) and high-risk group (HR), respectively. MRP1 mRNA expression in T-ALL group was 7.71 (6.49~14.35), which is higher than that of B-ALL (5.18(3.89~8.46)) (P<0.01). The rate of leukemia cells’ sensitivity to prednisone on 7th day was 70.6%in high expression group (n=34), which was signiifcantly lower than that in low expression group (n=33, 90.9%, P=0.035). The complete remission rateon 33th day was 64.7%in high expression group, and 87.9%in low expression group, which showed a signiifcant difference between them (P=0.026). Conclusions In children ALL, the expression of MRP1 is closely related with immunophenotyping, treatment response, hazard level and disease relapse.

The United Kingdom is the longest-serving community in the welfare states, and has been serving for more than sixty years so far. The construction of community care service supply model in the United Kingdom is deeply influenced by the neo-liberalism and neo-managerialism, which dominated the reform and development of pur-chasing community care services. Presently, China is actively promoting the government to purchase pension services of public health care combined with the long-term care, especially policy and determination of community-based de-velopment of an elders' service model. Based on the purchased services experience of the United Kingdom combined with the situation in China, this paper puts forward some suggestions such as the repositioning the role of the govern-ment, actively supporting the development of civil service organizations and perfecting the legal system of care serv-ices to be purchased, supporting the development of proposals to reduce the burden on the government and enhance the efficiency of care services through improving their quality.
