ObjectiveTo observe the therapeutic effect of standing bed on orthostatic hypotension with cervical spinal cord injury. Methods36 patients with cervical spinal cord injury were divided randomly into the standing bed group and routine treatment group. The blood pressure of all patients were measured every day during rehabilitation treatment. The function of spinal cord was assessed before and after treatment.ResultsThe function of sensory and motor in the two groups were all improved, but there was no statistical difference between the two groups in the grades of spinal cord function. There were 27 patients who had orthostatic hypotension in the study. All the patients with complete spinal cord injury suffered the orthostatic hypotension. There was no improvement in blood pressure of complete spinal cord injury after treatment. In incomplete spinal cord injury patients, there was a significant improvement and the difference of blood presure between lying and standing was decreased in standing bed group after treatment (P<0.05). Compared with routine treatment group, the blood pressure in standing bed group was improved (P<0.05). Conclusions Cervical spinal cord injury could have orthostatic hypotension. Complete spinal cord injury would suffer orthostatic hypotension in different degree. The standing bed treatment could improve the orthostatic hypotension in incomplete spinal cord injury.

ObjectiveTo observe the therapeutic effect and prognosis of nimodipine on severe traumatic brain injury. Methods64 patients with severe traumatic brain injury were divided into the nimodipine group(32 cases) and the routine treatment group(32 cases). The Glasgow Coma Scale(GCS) was assessed before and after the treatment. The Activities of Daily Living(ADL) and cognitive ability were evaluated in clear-headed patients. After 6 months follow-up, the Glasgow Outcome Scale (GOS), Bathel index and Mini Mental State Examination (MMSE) score were carried on.ResultsIn both of the two groups, GCS score were increased distinctively after treatment. The MMSE score in nimodipine group was higher than that of routine treatment group. There was no statistic difference in GOS and ADL between two groups after 6 months, but MMSE in nimodipine group was higher than that of routine treatment group. Conclusions Nimodipine could be helpful in cognitive function. The prognosis of severe traumatic brain injury lied on the degree of cerebral damage.

ObjectiveTo observe the effect of Nimodipine on the hemorrheology and brainstem auditory evoked potentials (BAEP) in the patients with vertebrobasilar insufficiency (VBI) and to explore the mechanism.Methods50 cases with VBI were divided into Nimodipine group (25 cases) and routine therapy group (25 cases). The hemorrheology and BAEP were measured before the treatment and 1 month later.ResultsThe blood viscosity,including the whole blood viscosity shear value, plasma viscosity and blood fat of patients with VBI was increased. The total abnormity rate of BAEP was 76%. The main abnormity was brainstem type. The hemorrheology and the function of nerve conduction were improved distinctly (P<0.05) after treatment. Compared with the routine therapy group, the level of plasma viscosity was decreased markedly (P<0.05) in Nimodipine group, and peak latency of V wave, interpeak latency of III-V and I-V were also improved significantly (P<0.05).Conclusions Nimodipine can improve the hemorrheology and the function of nerve conduction in patients with VBI.

Objective To study the effects of cripto on migration, invasion, and liver metastasis of colorectal cancer cell. Methods After human colorectal cancer cell line SW480 was transfected by cripto small interfering RNA (siRNA), the mRNA and protein level were determined by Real-time RT-PCR and Western blot, respectively. The migration and invasion ability were evaluated by wound-healing assay and boyden chamber model, respectively. Thirty nude mice model of liver metastasis from colorectal cancer was established by splenectomy. Results The siRNA could down-regulate the level of mRNA and protein of cripto in a dose- and time-dependent manner. Suppression of cripto expression could inhibit migration and invasion ability of human colorectal cancer cell in vitro. The metastastic rate and tumor nodules were lower in transfection with cripto siRNA than in two control groups in vivo. Conclusions Cripto gene might play an important role in regulation of liver metastasis from colorectal carcinoma cell, and suppression of cripto gene by siRNA can inhibit liver metastasis of colorectal cancer.

ObjectiveTo develop the manipulation and scoring system of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) into a Chinese software.MethodsThe manual manipulation and scoring system of LOTCA was developed into a technological procedure and changed into primary product of software through conforming computer programs such as Basic, C, C++ and Flash Maker. The primary product was tested in clinic and feedback suggestions were collected. The questions found during assessment and items with reliability and validity not satisfied were optimized.ResultsThe Chinese software of LOTCA, including mandarin and Cantonese, composed manipulation system, scoring system, administer system and affiliated system. It could run on systems of Windows 2000 and Windows XP.ConclusionThe Chinese software of LOTCA is objective, standard and convenient for clinic.

ObjectiveTo investigate the effects of infrared radiation and magnetic fields on the synovitis of rabbit with experimental knee osteoarthritis (OA).MethodsTwenty-four New Zealand grown rabbits were duplicated for OA model of the knee by extended fixation technique, and after 6 weeks, all rabbits were unchained from fixation. The rabbits were randomly divided into four groups: control group (no treatment), infrared group (treated with infrared radiation ), magnet-therapy group (treated with magnetic fields ) and the combined therapy group (treated with infrared radiation and magnetic fields). At the ends of the first, second and third week after treatment, 2 rabbits in each group were taken to measure the general change and histopathology of their synovium.ResultsCompared with other groups, the severity of synovitis (include the synovium line cells proliferation, the invading of granulation and blood vessels in the underlayer of synovium, the infiltration of inflammatory cells) declined significantly in combined therapy group. Scores of Ayral's index of combined group were significantly lower than other groups ( P<0.05), and there was no significant difference between infrared group and magnet-therapy group ( P>0.05).ConclusionThe combination of infrared radiation and magnetic fields can efficiently suppress the synovitis of OA and alleviate the tissue's destructions.

OBJECTIVETo explore mechanisms of acupuncture in treatment of vertebrobasilar insufficiency.

METHODSForty cases of vertebrobasilar insufficiency (VBI) were divided into an acupuncture group and a routine treatment group, 20 cases in each group. The acupuncture group were treated by routine treatment plus acupuncture. Transcranial Doppler ultrasonography and brain stem auditory evoked potentials (BAEP) before treatment and 2 weeks after treatment were determined to investigate the effects of acupuncture on blood flow velocity and brain electrophysiology in the patient of VBI.

RESULTSBefore treatment, the blood velocity of vertebral artery and vertebrobasilar artery at bilateral sides in the patient of VBI decreased as compared with the control group, and the abnormal rate of TCD was 75.0% (30/40) and the abnormal rate of BAEP was 70.0% (28/40), characterized with brainstem abnormality type; after treatment, the blood velocity in the two groups was improved and the abnormal rate of TCD was 47.5% (19/40), and the abnormal rate of BEAP was 45.0% (18/40). The nerve conduction of the two groups was improved, the peak latency of V wave and interpeak latency of III-V and I -V in the acupuncture group were improved significantly as compared with the routine treatment group (P < 0.05).

CONCLUSIONAcupuncture can improve the blood velocity of vertebrobasilar artery and the nerve conduction function of brainstem in the patient of vertebrobasilar insufficiency.
