Objective To investigate the expression of aquaporin 2 (AQP2) in an endolymphatic hydrops ani-mal model .Methods Forty adult guinea pigs were randomly divided into experiment group and control group (20 animals in each group ) . Guinea pigs in the experiment group were treated with deamino arginine vasopressin (DDAVP) intraperitoneally at the dosage of 4 μg · kg -1 · d-1 for 7 days ,while those in the control group were treated with physiological saline .The endolymphatic hydrops and expression of AQP2 in cochleas of all animals were evaluated by Hematoxylin and Eosin stain ,immunohistochemistry and Western blot .Results The endolymphatic hydrops in the experiment group were more severe than that in the control group(P<0 .05) .Expression of AQP2 were found in the stria vascularis and spiral ganglions in both groups with similar patterns .Both immunohistochem-istry and Western blot showed that the expressions of AQP2 in the experiment group were significantly stronger(P<0 .05 ) .Conclusion DDAVP can up-regulate the expression of AQP2 in the cochleae of guinea pigs ,thus may be closely related to the pathogenesis of endolymphatic hydrops .

OBJECTIVETo compare the difference in the efficacy on cervical type of cervical spondylosis (CS) between the combined treatment of sword-like needle and chiropractic spinal manipulation (the combined therapy) and the simple chiropractic spinal manipulation.

METHODSOne hundred and thirty-eight cases of cervical type of CS were randomized into a combined therapy group (76 cases) and a simple chiropractic spinal manipulation group (62 cases). In the combined therapy group, the sword-like needle therapy was applied at Fengchi (GB 20), Tianzhu (BL 10) and Jiaji (EX-B 2) C3-C5. The chiropractic spinal manipulation was used in combination. In the chiropractic spinal manipulation group, the simple chiropractic spinal manipulation was adopted. The treatment was given once every other day in the two groups, 10 days made one session. One session of treatment was required. Visual analog scale (VAS) score was observed before and after treatment in the two groups and the efficacies were compared between the two groups.

RESULTSVAS score after treatment was reduced obviously as compared with that before treatment in the patients of the two groups (both P < 0.01) and VAS score after treatment in the combined therapy group was lower than that in the simple chiropractic spinal manipulation group (1.50 +/- 0.58 vs 1.87+/-1.05, P < 0.01). In the combined therapy group, 48 cases were cured, 20 cases remarkably effective, 8 cases improved and 0 case failed. In the chiropractic spinal manipulation group, 30 cases were cured, 16 cases remarkably effective, 15 cases improved and 1 case failed. The overall efficacy in the combined therapy group was better than that in the chiropractic spinal manipulation (P < 0.05).

CONCLUSIONThe sword-like needle therapy combined with chiropractic spinal manipulation relieve effectively pain in cervical type of CS and the efficacy is superior to the simple chiropractic spinal manipulation.

Objective To analyze the cause of acute brain swelling,brain encephalocele in brain traumatic injury craniotomy,and the reason,diagnosis and treatment methods of progressive epidural hematoma.Methods The clinical data of 381 patients with brain traumatic injury craniotomy were retrospetively analyzed.Of 318 patients,27cases had progressive epidural hematoma during operation.Results 9 cases died because of functional failure of brain stem,the other 18 cases were all clinically cured.Conclusion If acute brain swelling and encephalocele occured during operation,the cause should be found quickly,especially when there was skull fracture or epidural hematoma on the contralateral brain,the head CT and operation should be taken immediately,and the bulging brain tissue should not be removed blindly,and the skull should not be forced to close,otherwise the prognosis maybe poor.

Objective To develop rats model for human dilated cardiomyopathy(DCM).Methods Male Sprague-Dawley rats were administered adriamycin intraperitoneally 2.8 mg/kg? week)for 11 weeks,and then observed for 2 weeks.Plasma levels of brain natriuretic peptide(BNP)were studied by ELISA;left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD)and left ventricular ejection fraction(LVEF)were measured by echocardiogram;and morphology of the hearts and pathological lesions of cardiac muscle tissues were observed.Results(1)The levels of BNP of the DCM group were higher than those of the normal group(P

OBJECTIVESTo measure the linear polyethylene wear with use of a computer-assisted two-dimensional method, and to evaluate the relationship between wear and long-term clinic-radiological findings.

METHODSBetween December 1991 and December 1995, the senior author performed 40 primary total hip arthroplasties with use of H/G porous-coated acetabular component. Radiographs of 40 H/G cementless total hip arthroplasties were examined for osteolysis, radiolucent line, cup migration and so on. To measure the linear polyethylene wear, migration in the femoral head center relative to the cup shell center was calculated on digitized consecutive radiographs with special computer software program.

RESULTSThe minimum follow-up was 10 years. Total linear wear was 2-8 mm, the mean rate of linear polyethylene wear was (0.32+/-0.31) mm/year. Twelve acetabular components (30%) were revised at an average follow-up point of 12 years. Three types of polyethylene liner failure were identified: wear-through of the polyethylene liner with resultant metallosis (5 hips), excessive wear necessitating revision (5 hips), and polyethylene liner dissociation without gross evidence of wear (2 hips).

CONCLUSIONSHigh wear rates and femoral and acetabular osteolysis have been and still are the main problems in uncemented total hip replacement. There is clear relationship between wear and acetabular osteolysis or loosening of the prostheses. The poor long-term results with these uncemented total hip arthroplasties illustrate the necessity of regular radiographic evaluation in order to detect osteolysis and liner failure, which are both generally asymptomatic until catastrophic failure appears.

The authors designed to separate, purify and determine the monosaccharide composition of the polysaccharide from Cordyceps militaris, and study its effect on reverse cholesterol transport in vivo by isotope tracing assay. Polysaccharides were separate and purify by ion exchange column Q-sepharose Fast Flow and size exclusion column Sephacryl S200HR; the molecular weight and monosaccharide composition of the polysaccharides were determined by high performance gel permeation chromatography and high performance liquid chromatography coming with pre-column derivation, respectively. Finally, three purified polysaccharides CMBW1, CMBW2 and CMYW1 were obtained, their total carbohydrate contents were 87%, 89%, 95%, respectively; their protein contents were 6.5%, 1.3%, 2.8%, respectively; their molecular weights were 772.1, 20.9, 13.2 kDa, respectively; CMBW1 was composed of mannose, glucosamine, rhamnose, glucuronic acid, glucose, galactose and arabinose with a molar ratio of 7.25: 0.17: 1.29: 0.23: 6.30: 11.08: 0.79; CMBW2 was composed of mannose, glucosamine, galactose and arabinose with a molar ratio of 2.40: 0.16: 2.92: 0.24; CMYW1 was composed of mannose, glucosamine, glucuronic acid and glucose with a molar ratio of 0.59: 0.57: 0.45: 25.61. Polysaccharide at 50 mg x kg(-1) could significantly improve the transport of 3H- cholesterol to blood and excretion from feces. All of the three purified polysaccharides CMBW1, CMBW2 and CMYW1 were heteropolysaccharide; and they could improve reverse cholesterol transport in vivo, the underlying mechanisms are being studied.
