Objective: To observe the therapeutic effect of sinew-regulating bone-setting manipulations for knee osteoarthritis (KOA) model rabbits and its impacts on the chondrocyte apoptosis rate and the levels of interleukin (IL)-1β and nitric oxide (NO). Methods: According to the random number table method, 30 New Zealand white rabbits were divided into a normal group (n=9) and a modeling group (n=21). Rabbits in the modeling group were used to establish KOA models with the modified Hulth method. At the 8th week, three rabbits were sacrificed to verify the model and the remaining 18 rabbits were randomly divided into a model group (n=9) and an intervention group (n=9). Rabbits in the normal group and model group were bred routinely without any intervention. Rabbits in the intervention group were treated with the sinew-regulating bone-setting manipulations, 10 min/time, once every other day for a total of 20 times. The Lequesne MG knee function rating was used to evaluate the behavioral differences of the rabbits in each group. The Pelletier score was used to evaluate the general changes of the rabbits. The Mankin score was used to evaluate the pathology of knee cartilages. The enzyme-linked immunosorbent assay and nitrate reductase methods were used to determine the levels of IL-1β and NO in serum and synovial fluid of each group, respectively. In situ terminal deoxynucleotidyl transferase-mediated nick and labeling method was used to determine the apoptosis of chondrocytes in each group. Results: Compared with the normal group, the scores of Lequesne MG, Pelletier and Mankin, and the levels of IL-1β and NO in the model group were increased (P<0.05), which indirectly indicated the success of the model. Compared with the model group, the scores of Lequesne MG, Pelletier and Mankin, IL-1β and NO levels, and chondrocyte apoptosis rate of the intervention group were decreased, and the differences were statistically significant (P<0.05). Conclusion: The sinew-regulating bone-setting manipulations can reduce the levels of IL-1β, NO, and chondrocyte apoptosis rate, and delay the articular cartilage degeneration, therefore, having a good therapeutic effect on KOA.

Objective To find the effective therapeutic arrangement through investigating the clinical characteristics of chronic cardiac insufficiency with anaemia. Methods A total of 46 cases of anemia from 315patients who had been admitted to department of cardiology, the First Affiliated Hospital, Harbin Medical University for chronic cardiac insufficiency with anaemia were selected. They were divided into two groups. There were 22 patients in the first group who only accepted treatment to improve cardiac function (normal cardiac, diuretic,vasodilator therapy, etc.), and 24 patients in the second group who accepted treatment to improve cardiac function while receiving anti-anemia therapy treatment, oral ferrous sulfate tablets(0.3 g/tablet), 1 tablet each time, 3 times a day and(or) 2 times per week subcutaneous erythropoietin 3000 U. The hemoglobin(Hb), red blood cell(RBC) ,hematocrit (HCT), left ventricular ejection fraction (LVEF), fractional shortening (FS), stroke volume (SV) , cardiac output(CO) and E peak and A peak ratio(E/A) were observed before and after treatment. By logistic regression, grade grade Ⅱ , Ⅲ , Ⅳ, the incidence of anaemia were 7.9% (10/126), 19.2% (23/120) and 24.6% (17/69),respectively. Grade Ⅱ compared with grades Ⅲ, Ⅳ, the difference was statistically significant (x2 = 4.08, 3.12, all (3.49 ± 0.17) × 1012/L, (0.36 ± 0.08)%, (48.9 ± 3.11)%, (15.6 ± 1.8)%, (38.9 ± 3.7)%, (4.4 ± 1.6)% and (130.7 ±5.75)g/L, (4.12 ± 0.25) × 1012/L, (0.43 ± 0.02)%, (58.5 ± 2.65)%, (18.0 ± 2.5)%, (49.1 ± 7.7)%, (5.1 ± 1.2)%in the first and second groups, respectively. The difference between the two groups was statistically significant(t =value of Hb, RBC, HCT, LVEF, FS,SV, CO were (102.7 ± 6.93)g/L, (3.41 ± 0.12) × 1012/L, (0.35 ± 0.07)%,(47.5 ± 2.86)%, (16.0 ± 2.4)%, (38.2 ± 7.9)%, (3.7 ± 1.4)%, respectively. Compared with those after treatment,the difference was statistically significant (t = 15.632, 13.325, 5.569, 17.182, 3.186, 2.999, 3.074, all P < 0.05);Ⅳ-level relative risk were 1.62, 3.14(P < 0.05 or < 0.01) . Conclusions Based on the standard treatment with treatment of anemia, cardiac contractile function can be improved.

OBJECTIVETo establish the steriod-induced osteoporosis model with the type of Kidney-Yin deficiency.
METHODSTotally 45 female Kunming mice were randomly divided into normal group,model group and Liuwei Dihuang pills(Chinese character: see text)group. The model was established by intramuscular injecting of Dexamethasone. Liuwei Dihuang pills (Chinese character: see text) group was administered orally with Liuwei Dihuang pills (Chinese character: see text). The signs and symptoms of mice were observed dynamically. All the animals were sacrificed at the end of the 6th weeks. The level of ACTH, cAMP, cGMP, TSH and E2 in serum were detected to evaluate deficiency of Kidney-Yin. Morphological changes and bone density were observed to evaluate osteoporosis.
RESULTS(1) Compared with control group, mice in model group appeared obvious Kidney-Yin deficiency symptoms, including hair dry, restlessness, excitability, hard stool, and yellow. (2) Compared with control group,the weight of mice in model group gained slower (P<0.01); the index of adrenal gland,liver and spleen decreased (P<0.01, P<0.01 ,P<0.01); the level of ACTH and TSH increased (P<0.01 ,P<0.01), the level of E2 decreased (P<0.01) and the ratio of cAMP/cGMP increased (P< 0.05). (3)Compared with control group,the bone density of lumbar vertebra and femur in model group were significantly decreased (P<0.01, P<0.05); HE staining revealed osteoporosis in model group mice. (4)However, the Liuwei Dihuang pills (Chinese character: see text) group can partly antagonize the inhibition of the HPA axis, alter the disordered sex hormone and the ratio of cAMP/cGMP, and reverse the osteoporosis partly.
CONCLUSIONthe model of osteoporosis with type of Kidney-Yin deficiency could be established by Dexamethasone intramuscular injection. With less interference, it wight be a stable and reliable modeling method for integration of disease and syndrome in TCM.

?AlM: To investigate the expression of miR-181 in the lens tissue of cataract and the regulating mechanism of miR-181 on apoptosis of human lens epithelial cell.
?METHODS:Real time q-PCR was used to measure the expression of miR-181 in the anterior lens capsules of age - related cataract and human lens epithelial cell apoptosis model. miR- 181 mimic and inhibitor were transfected using Lipofectamine 2 000 to regulate the expression of miR-181, and then Real time q-PCR was used to verify transfection efficiency. Flow cytometry was used to detect the change of cell apoptosis rate.
? RESULTS: Compared with control group, the expression of miR-181 was significantly higher in both the anterior lens capsules of age-related cataract and human lens epithelial cell apoptosis model; the relative expression of miR-181 in lens epithelial cells transfected with miR-181 mimic was increased, whereas decreased in cells transfected with miR-181 inhibitor;the apoptosis rate of cells transfected with miR - 181 mimic was increased, while reduced in miR-181 inhibitor group. Each result was statistically significant (P<0. 01).
?CONCLUSlON:High expression of miR-181 is detected in anterior lens capsule of age-related cataract. miR-181 might play a certain role in the pathogenesis of cataract via promoting human lens epithelial cell apoptosis. miR-181 probably becomes a new approach for the nonoperative treatment of cataract, but the concrete mechanism still needs to be further studied.

OBJECTIVETo study the molecular mechanism of curcumin in human esophageal carcinoma cell line (EC109).
METHODSEC109 cells were cultivated in vitro. When 80%-90% confluence was reached, they were treated with curcumin in different concentrations (15-120 µmol/L). The effects on cell proliferation were examined by CCK-8 colorimetry. The ultrastructure of EC109 cells were detected with transmission electron microscope(TEM). The cells apoptosis was observed with laser confocal microscope(LCM) by AnnexinV-FITC/PI double staining. The proteins level of PTEN, AKT, GSK3β and Caspase 3 were tested by flow cytometry(FCM) .
RESULTSCCK-8 test showed that curcumin could inhibit the proliferation of EC109 cells in a time- and concentration-dependent manner. TEM and LCM examinations indicated that curcumin could make EC109 cells apoptosis. The data of FCM showed that curcumin could increase the expression of PTEN, GSK3β and Caspase 3, decreased the expression of AKT.
CONCLUSIONThe effects of curcumin on inhibiting proliferation and promoting apoptosis of EC109 cells were related with increased expression of PTEN and inhibition of PI3K/AKT signaling pathway.
