OBJECTIVETo compare therapeutic effects between arthroscopic medial retinaculum plication and plaster external fixation for the treatment of acute patellar dislocation.

METHODSFrom February 2006 to October 2012,29 patients with acute patellar dislocation were divided into two groups: operation group and non-operation group. The patellar dislocation duration was 2 weeks. In operation group, there were 7 males and 10 females, with an average age of (16.2 ± 6.2) years old, and the patients were treated with arthroscopic medial retinaculum plication. In non-operation group, there were 5 males and 7 females,with an average age of (16.3 ± 5.0) years old,and the patients were treated with plaster external fixation. The Kujala scores, patellar tilt angle measured on CT film, apprehension test and recurrence rate of patellar instability were observed before and 1 year after treatment.

RESULTSIn operation group, the pre-treatment and post-treatment patellar tilt angles had no statistical difference, but the post-treatment Kujala score was lower than that of pre-treatment; while in non-operation group, the post-treatment patellar tilt angle was larger than that of pre-treatment, and the post-treatment Kujala score was lower than that of pre-treatment. At 1 year after treatment, the patellar tilt angle (21.2 ± 5.3) of patients in non-operation group was larger than (13.5 ± 3.5) of operation group, and the Kujala score 73.3 ± 10.5 of patient in non-operation group was lower than 84.1 ± 5.6 of operation group.

CONCLUSIONDuring 1 year after operation, arthroscopic medical retinaculum plication is a more effective treatment for acute patellar dislocation compared with plaster external fixation.

Objective To determine,the clinical significance of serum myocardial enzymes (Mb,cTNI, CK,CK-Mb,AST,LDH) in the classification of the disease severity of non-cardiogenic critically-ill patients. Compared with APACHEⅡscore concerned as the standard diagnosis of the critical ills,these biomarkers were investigated for the evaluation possibility of the degree and the prognosis of the critical ills.Method Patients admitted to our EICU were consecutively collected for the research from April to December in 2005 and the myocardial enzymes,and routine serum biochemical test and APACHEⅡscore were detected simultaneously.All the patients were classified to three groups according to the APACHEⅡscore (mild group,APACHEⅡ25) and two groups (survive group and death group) according to the prognosis.All the patients were followed up till recovery/discharge or death. Covariance,Wilcoxon and x~2 were used for the statistical analysis.Results The myocardial enzymes rose when the disease deteriorated and the APACHEⅡscore went up.AST,LDH,CK,CK-Mb,Mb were significantly different in the three groups according to the APACHEⅡscore (P

BACKGROUND: The study aimed to explore the effects of hypothermia state induced by 4 oC normal saline (NS) on liver biochemistry, enzymology and morphology after restoration of spontaneous circulation (ROSC) by cardiopulmonary resuscitation (CPR) in swine. METHODS: After 4 minutes of ventricular fibrillation (VF), standard CPR was carried out. Then the survivors were divided into two groups: low temperature group and normal temperature group. The low temperature (LT) group (n=5) received continuously 4 oC NS at the speed of 1.33 mL/kg per minute for 22 minutes, then at the speed lowering to 10 mL/kg per hour. The normal temperature (NT) group (n=5) received NS with normal room temperature at the same speed of the LT group. Hemodynamic status and oxygen metabolism were monitored and the levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were measured in blood samples obtained at baseline and at 10 minutes, 2 hours and 4 hours after ROSC. At 24 hours after ROSC, the animals were killed and the liver was removed to determine the Na+-K+-ATPase and Ca2+-ATPase enzyme activities and histological changes under a light or electron microscope. RESULTS: Core temperature was decreased in the LT group (P<0.05), while HR, MAP and CPP were not significantly decreased (P>0.05) compared with the NT group (P>0.05). The oxygen extraction ratio was lower in the LT group than in the NT group (P<0.05). The serum levels of ALT, AST and LDH increased in both groups but not significantly in the LT group. The enzyme activity of liver ATP was much higher in the LT group (Na+-K+-ATP enzyme: 8.64±3.32 U vs. 3.28±0.71 U; Ca2+-ATP enzyme: 10.92±2.12 U vs. 2.75±0.78 U, P<0.05). The LT group showed less cellular edema, inflammation and few damaged mitochondria as compared with the NT group. CONCLUSION: These data suggested that infusing 4 oC NS continuously after ROSC could quickly lower the core body temperature, while maintaining a stable hemodynamic state and balancing oxygen metabolism, which protect the liver in terms of biochemistry, enzymology and histology after CPR.

-2,and T)was detected on exon 11 in the mutational analysis of GABRG2.Our results indicate that genomic variations of GABRG2 are not likely to be substantially involved in the etiology of GEFS+in this family. Conclusion Our study fails to provide evidence supporting a causal relation between the SCN1A,SCN1B, GABRG2 mutation and the etiologic genes in this family,which indicates that GEFS+has with phenotypic and genotypic heterogeneity.

OBJECTIVETo assess the morphologic changes in traumatic cerebral infarction and to discuss its mechanism.

METHODSSpecimens from seventeen cases of cerebral infarction were selected from 81 patients with severe brain injury, and subject to routine gross and histological examinations.

RESULTS(1) The cerebral infarction in all cases was hemorrhagic in nature with a wedged or irregular shape upon gross inspection. The lesions were found in occipital gyrus (8 cases), occipital lobes (3 cases), basal nuclei (3 cases), cingulate gyrus (2 cases), and lateral occipitotemporal gyrus (1 case). Histologically, the lesions were located at the junction between the cortex and medulla, showing congestion, edema, hemorrhage, necrotic nerve tissue and blood vessels. In severe cases, the lesion extended into the entire cortex and subarachnoid spaces. (2) Swelling of the brain and cerebral hernia were found in all cases, 8 of which demonstrated that the posterior cerebral artery was compressed and stenotic within the space between the crus cerebri and uncus.

CONCLUSIONBrain tissue necrosis in traumatic cerebral infarction is the result of brain swelling and cerebral hernia formation, following congestion, bleeding and ischemia due to vasculature compression.

Objective To observe the clinical efficacy of acupuncture plus medicine and function training in treating post-stroke shoulder-hand syndrome. Method Sixty patients with post-stroke shoulder-hand syndrome were randomized into a treatment group of 30 cases and a control group of 30 cases. The treatment group was intervened by acupuncture plus medicine and functional training, while the control group was only by functional training. Before and after intervention, the hand swelling degree, Visual Analogue Scale (VAS), shoulder joint motion scale, Fugl-Meyer Assessment (FMA) scale were used to measure the swelling and pain of hand, motion of shoulder, and motor function of upper limb. Result After intervention, the swelling and pain of hand, motion range of shoulder and motor function of upper limb were significantly improved in both groups (P<0.01), and the improvements in the treatment group were more significant than that in the control group (P<0.05). Conclusion Acupuncture plus medicine and function training can enhance the efficacy in treating post-stroke shoulder-hand syndrome, superior to pure function training.

OBJECTIVETo analysis the changes of two chemical constituents, namely 2, 3-dihydro-3, 5- dihydroxy-6-methyl-4H-pyran-4-one (DDMP) and 5-hydryoxymethyl-furfural (5-HMF) produced in Radix Polygoni Multiflori after processing, with processing time, and to determine the contents of 5-HMF in samples of Radix Polygoni Multiflori and Radix Polygoni Multiflori preparata.

METHODAn HPLC method was applied with a Zobax SB-C18 (3.9 mm x 150 mm, 5 microm) column by a elution using methanol-water (10: 90) as the mobile phase. The detection was set at UV 280 nm.

RESULTThe contents of DDMP were increasing with the processing time until 24 hour, followed by a decrease until 60 hour process. The contents of 5-HMF were increasing gradually throughout the 60 hour steaming process. The contents of 5-HMF in 11 samples of Radix Polygoni Multiflori preparata were from 0.013% to 0.101%, and only one in 4 samples of Radix Polygoni Multiflori containing trace amount of 5-HMF.

CONCLUSIONThe chemical components in Radix Polygoni Multiflori were changed during the processing procedures. Therefore, the processing of Radix Polygoni Multiflori should be controlled and standardized.
