Objective: To investigate the effects of Jiaosanxian (JSX, consisted of stir-baked Hordei Fructus Germinatus-Crataegi Fructus-Massa Fermentata Medicinalis) on reducing blood lipid. Methods: The model of hyperlipidemic mice was established by feeding high-fat diet. Kunming mice were randomly divided into six groups: blank, hyperlipidemic, Zhibituo, low-, mid-, and high-dose [100, 200, and 400 mg/(kg·d)] JSX groups, and were continuously ig administered for 28 d. The contents of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) in serum and liver and liver index were determined. Results: The contents of TC, TG, and LDL-C in serum or liver were decreased significantly but the contents of HDL-C were increased more significantly in the mid- and high-dose JSX groups than those in hyperlipemic group. The weight and liver index were decreased significantly with the dose increasing of JSX. The lipid-decreasing effects were improved with the dose increasing. Conclusion: These results suggest that JSX has the significant effects on hyperlipidemia. It could provide the experimental basis for the clinical use of JSX for the treatment of hyperlipidemia. © 2013 Tianjin Press of Chinese Herbal Medicines.

This study was aimed to evaluate the reliability and validity of the Traditional Chinese Medicine Self Rate Health Assessment Questionnaire (TCM-SRHAQ). A total of 859 middle age and aged cases were enrolled in a cross-sectional study, which were evaluated by the questionnaire. The salivary level of ɑ-amylase was tested at the same time. The results showed that the split-half reliability coefficient was 0.91, which can highly differentiate the health level of the crowd. The spearman correlation coefficients between items in the “spleen deficiency” sub-scale were all higher than 0.3. While the correlation coefficients between items were less than 0.25. Salivary level of ɑ-amylase was used as indicator. The “spleen deficiency” sub-scale showed high validity in identifying spleen-qi deficiency people from healthy people. It was concluded that TCM-SRHAQ showed good reliability and validity in this study, which indicated it can be used as a valuable measurement for assessing different types of health status, especially the spleen-qi deficiency type.

BACKGROUND:C2 transpedicle screw fixation for Hangman fractures has been paid more attention due to reliability and no loss of physiological function.However,there are lacks of biomechanical evidences for indication treatment because the fixation is single segmental.OBJECTIVE:To investigate the biomechanical stability of C2 transpedicle screw fixation for Hangman fractures.DESIGN,TIME and SEITING:This was a contrast study which was performed at the General Key Laboratory of Biomechanics,First Military Medical University of Chinese PLA from May to August 2004.MATERIALS:AO-universal titanium alloy transpedicle screw of 18 25 mm in length and 3.5 mm in diameter was adopted in this study.Six fresh C1-C4 cervical vetebrae samples were ordiually made into type Ⅰ,ⅡA,and Ⅱ Hangman fracture models.METHODS:After transpedicle screw fixation.Hangman fracture models were measured by non-destroyed style with spinal anterior flexion/posterior extension,left/right lateral curvature,and left/right axial direction.Loading/unlonding circulation was performed three times during each testing.Kinematics indicators were measured on the 3rd circulation.MAIN OUTCOME MEASURES:Spinal motor images at zero load and maximal load were obtained with laser photoscanning(0.1% in precision),and the corresponding systematic software was adopted to calculate 3D range of movement.RESULTS:The relative stability of type Ⅰ Hangman fracture models after C2 transpedicle screw fixation was 100.62%(inflexion),96.91%(posterior extension),99.19%(lateral curvature),and 97.12%(rotation)as compared to control group (P＞0.05).The relative stability of type Ⅱ Hangman fracture models after C2 transpedicle screw fixation was 47.84%(inflexion),21.29%(posterior extension),65.98%(lateral curvature),and 41.69%(rotation)as compared to control group (P＜0.05).CONCLUSION:Biochemical evaluation suggests that type Ⅰ and Ⅱ A Hangman fractures do fit for C2 transpedicle screw fixation,and the fixation may generate well physiological fixation or stability.However,stability of type Ⅱ Hangman fracture is poor,so it is not suitably adopted single transpedicle screw fixation.

BACKGROUND: Decompression-internal fixation is needed in the treatment of atlantoaxial dislocation accompanying with spinal compression caused by cranium-neck junction area malformation and other diseases.Different internal fixation methods are chosen according to different conditions, including anterior atlantoaxial internal fixation, posterior atlantoaxial internal fixation or occipitocervical internal fixation. Transoralpharyngeal atlantoaxial plate internal fixation is a method for atlantoaxial anterior fixation. It is developed recently and used for difficult and complicated atlantoaxial dislocation induced by congenital disease, trauma or rheumatoid arthritis.OBJECTIVE: To probe into the clinical application of transoralpharyngeal atlantoaxial reduction plate system in the atlantoaxial dislocation caused by obsolete odontoid fracture.DESIGN: Single Sample observation SETTING: Department of Orthopaedics, Guangzhou General Hospital of Guangzhou Military Medical University of Chinese PLA PARTICIPANTS: Twelve patients with atlantoaxial dislocation caused by obsolete odontoid fracture were selected in the Department of Orthopaedics, General Hospital of Guangzhou Military Medical University of Chinese PLA from January 2003 to October 2005. Among them, 7 were male and 5 were female, they were aged 47 years on average ranging from 36 to 59 years. The mean injured time was 19 months ranging from 4.5 to 36 months; 6 patients were graded as C degree, 3 as D degree and 3 as E degree in Frank gradation.METHODS: Twelve obsolete odontoid fracture caused by atlantoaxial dislocation underwent transoralpharyngeal anterior decompression. Transoralpharyngeal atlantoaxial reduction plate system was used in reduction and fixation. Autogeneic ilium was implanted into bilateral articulatio atlantoepistrophica.MAIN OUTCOME MEASURES: ① Frank gradation of patients at the 4th week after operation. ② whether the internal fixation is loose or not after operationRESULTS: ①Frank gradation at the 4th week after operation: Among the 6 patients who were primarily graded as C degree, 4 patients improved to be E degree and 2 patients D degree; Three patients who were primarily graded as D degree all improved to be E degree; Patients who were primarily graded as E degree did not changed. ② Except for one patient who suffered dislocation again for loosening of screw caused by tumble, the other patients had firm fixation, ideal fusion and satisfying spinal decompression.CONCLUSION: Transoralpharyngeal atlantoaxial reduction plate system finishes atlantoaxial reduction and fixation once. It avoids conducting posterior fusion fixation operation after anterior decompression. It also avoids fetal injury for spinal cord caused by extreme atlantoaxial unsteadiness in the process of movement and turning over.

Objective To investigate the full-term newborn′s weight in Zhengzhou city and nearby areas around Zhengzhou in Henan province.Methods Each group newborn′s weight was divided with sex and city.We studied the regularity of full-term newborn′s weight,and examined the cause of the newborn′s weight rising.Results The average newborn′s weight in Zhengzhou was (3449.06?453.97) g,which in nearby areas around Zhengzhou was (3352.07?429.91) g.The average newborn′s weight in Zhengzhou was 86.97 g higher than other cities (P

Objective To evaluate the biomechanical characteristics and the clinical advantage of transoral atlantoaxial reduction plate(TARP)Ⅲ.Methods Design of TARP-Ⅲ was based on TARP-Ⅱ.The screw hole in the axis was moved 1-2 mm upwards and inwards in a plate which turned a vertebral screw into a pedicle screw or an articular process screw.A polyaxial self-lock ring and polyaxial guiding drill were added to the crew hole of the plate.Finally,the withdrawal resist ence force of the three axis screws was tested and TARP-Ⅲ was used in 44 patients with complicated irreducible atlantoaxial dislocation.The axis was fixed with the pedicle screw or the articular process screw.Results The maximum withdrawal resist ence force of the anterior pedicle screw,the articular process screw and the vertebral screw in the axis was(593.1 ± 97.8)N,(469.9 ± 73.3)N and(395.2 ± 75.1)N respectively,with statistical difference between groups among three fixation methods(P ＜ 0.05).All 44 patients were followed up for 5-38 months(average 18 months),which showed complete anatomic reduction in 36 patients and appropriate anatomic reduction in eight,with basic correction of the angles between the brain stem and the spinal cord and sufficient decompression of the spinal cord.The decompression rate of the cervical spinal cord was average 88.2% according to the Yin evaluating method of cervical cord decompression.The improvement rate of spinal cord function was average 76.6% according to Japanese Orthopaedic Association(JOA)score.Conclusion With the design of polyaxial self-lock mechanism,TARP-Ⅲ with the pedicle screw or the articular process screw surpasses TARP-Ⅱ with vertebral screw in aspect of biomechanics.

OBJECTIVETo investigate the treatment for traumatic intervertebrae disk herniation in cervical thoracic junction.

METHODSFrom 2003 to 2008, there were 10 patients with trautimatic intervertebral disk herniation in cervical thoracic junction, which included 6 males and 4 females, aged from 23 to 66 years (means 41.5 years). All of them were performed through the transforminal approach combined with internal fixation. After operation all patient underwent hyperbaric oxygen treatment. The function of spine was evaluated by JOA score system.

RESULTSAll patients were followed up for 8 to 16 months(means 13 months). All patients got recovery of spine function to some extent except one case with complete spine damaged. The JOA scores was improved from (8 +/- 3) before operation to (15 +/- 2) after operation.

CONCLUSIONEarly and effective treatment by transforminal operation could be helpful for the recovery of spine function.

OBJECTIVETo compare the clinical outcomes of open surgical peritoneal dialysis catheter (PDC) insertion with guide wire and the outcomes of PDC insertion without guide wire.

METHODSData of the patients receiving open surgical Tenkchoff straight catheter insertion in our department from January 2005 to January 2011 were retrospectively analyzed. The 117 patients in whom PDC insertion was conducted with the guidance of guide wire were enrolled into group A, and the 121 cases receiving PDC insertion without guide wire were enrolled into group B. The incidences of post-operative complications (catheter obstruction, catheter displacement, bloody dialysate, and dialysate leakage), catheter survival, and patient survival rates were compared between the 2 groups.

RESULTSThe baseline characteristics (gender, age, body mass index, prothrombin time, activated partial thromboplastin time, platelet count, serum creatinine, follow-up time, primary diseases, and outcomes) of the 2 groups were comparable (all P>0.05). In post-operative complications, only the incidence of early bloody dialysate showed significant difference, being 16.2% in group A and 7.4% in group B (P=0.04). Catheter and patient survival rates were not significantly different between the two groups. Overweight patients showed a higher incidence of catheter obstruction compared with normal weight patients [16.0% (4/25) vs.3.3% (7/213), P=0.02], but no differences in post-operative complications were found among overweight patients between the 2 groups.

CONCLUSIONSOpen surgical Tenkchoff straight catheter insertion without guide wire does not lead to higher risk of post-operative complications and catheter removal. It may be an alternative option when guide wire is not available.
