Objective To discuss pathogenesis of low back pain induced by chronic compartment syndrome. Method Thirty patients who had definite chronic lumboscaral compartment syndrome without other lumbal diseases were choosed respectively to test muscle force of lumbar and abdomen,intra-sacrospinal muscle pressure,blood routine,ESR,CK,CK-MM,LDH and LDHs.All patients received decompressive operation.Skeletal muscle specimens taken from sacrospinal muscle in each operation were possessed for histological and ultrastructuml observation. Result All of enzyme tests were normal.The author could observe the dissolved degeneration of part of sacrospinal muscle fibers,muscle fiber hypertrophy,and a small quantity of inflammatory cell infiltration with a light microscope.Focal solution of muscle fiber,the aggregation of mitochondria around the nucleus,the increase of lipid droplet and lysosome in cyte,and the proliferation and differentiation of muscle satellite cell could be observed with an electron microscope. Conclusion Pathogenesis of chronic lumboscaral compartment syndrome may be as followed.Intra-compartmental pressures increase,causing metabolism disturbance of the tissues under fascia compartment,damaging skeletal muscle chronically,then inflammatory factors are released,which stimulates posterior branch of spinal nerves,and finally induces low back pain.

Objective: To study the pharmacodynamic differences between Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma on the treatment of adjuvant arthritis. Methods: Wistar rats were randomly divided into blank control group (normal saline), model control group (normal saline), Tripterygium wilfordii glycosides (TWG) group (9.45 mg/kg), low-and high-dose (1.080 and 4.320 g/kg) Simiao Pills (crude Atractylodis Rhizoma) group, low-and high-dose (1.080 and 4.320 g/kg) Simiao Pills (stir-baked Atractylodis Rhizoma with bran) group. Except the blank control group, the other groups were modeled to adjuvant arthritis with complete Freund's. Paw edema value, spleen and thoracic gland indexes, serum interleukin-1β (IL-1β), and nitric oxide (NO) were observed. Results: Both Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma could inhibit paw edema, decrease spleen index, advance the thoracic gland index, and decrease IL-1β and NO. The Simiao Pills with crude Atractylodis Rhizoma showed better effects. Conclusion: Both Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma show a certain therapeutic effect on adjuvant arthritis, but the crude Atractylodis Rhizoma is in favor of the efficacy of Simiao Pills.

Objective To evaluate the cardiac function changing before and after resection of pituitary tumor in patients with pituitary adenoma complicated with dilated cardiomyopathy with retrospective analysis method.Methods The clinical data of 14 cases of patients with pituitary adenoma complicated with dilated cardiomyopathy,treated with resection of pituitary tumor,in PLA General Hospital,from 2005 to 2011,were collected and analyzed.Comparative analysis of cardiac function were made in these patients before and after the surgery,also with the postoperative recovery status,using echocardiography and other noninvasive detection means to detect the growth hormone ( GH),left ventricular end-diastolic diameter (LVEDD),septal thickness (ST),left ventricular posterior wall thickness (LVPWT),left ventricular ejection fraction (LVEF) values.Results After the resection of pituitary tumor,the LVEDD,ST,LVPWT,LVEF levels were all significantly better than that before the surgery.Before the surgery the GH,ST,LVPWT,LVEF levels were 93.89 μg/L,11.13 mm,43.92％ and 10.53 mm,while those after the surgery were 5.16 μg/L,10.64 mm,49.28％ and 8.87 mm.The difference of the GH level before and after the surgery was correlated with the difference of ST,LVEDD and LVEF in a linear manner.Conclusions Recection of pituitary tumor can significantly improve the cardiac function in patients with pituitary adenoma complicated with dilated cardiomyopathy,and the cardiac function improving level is correlated with the difference of GH levels before and after the surgery.

Aim To investigate the expression of CD31 , CD105 , HIF-1αand VEGF in xenografts tumor of HT-29 tumor cells during different stages of growth. Methods HT-29 tumor cells were transplanted into nude mice, the tumor was removed when the tumor volumes reached <100 mm3 , 100 ~300 mm3 and >300 mm3 respectively. Immunochemical method was a-dopted to detect the expression of CD31 , CD105 , HIF-1α and VEGF. Results HT-29 xenografts tumor vol-umes <100 mm3 , 100 ~300 mm3 , and >300 mm3 showed expressions with CD31-MVD at 37.40±4.17 , 18.80±1.72 and 14.20±2.23 respectively; CD105-MVD at 22.80 ±3.54 , 15.60 ±1.35 and 10.20 ±2.48; positive expression rate of VEGF was 26.20%
±0.83%,40.73% ±6.29% and 13.41% ±1.20%respectively; while positive expression rate of HIF-1αwas 3.20% ± 2.97%, 11.89% ± 1.94% and 80.62% ±3.47% respectively. On the other hand, for different volumes group, CD31-MVD, CD105-MVD, VEGF and HIF-1αexpression ratios had signifi-cant differences ( P <0.01 ) . Conclusions The ex-pression of MVD and vascular-related factors within the tumor caused by HT-29 xenografts tumor in nude mice at different growth stages was varied. There was a cer-tain correlation between tumor volume and MVD, VEGF, HIF-1α.

Objective:Our purpose was to establish an ideal chronic pressure-afterload heart failure rat model which has the transition from cardiac hypertrophy to heart failure. Methods: Chronic pressure-afterload heart failure rat model was induced by gradually constricting the ascending aorta of young rats. Young rats were randomly divided into 2 groups: the constricted and sham-operated groups. Clinical manifestation, tail-cuff blood pressure, organ weight, and hemodynamic data were observed at various time after operation. Results: The overall survival rate was 87%. Tail-cuff pressure began to increase in 4 weeks after operation. Left ventricular hypertrophy appeared in 12 weeks and heart failure in 5 months. Conclusion:It's a practical and reproducible model of cardiac hypertrophy that progresses to chronic heart failure.
