ObjectiveTo investigate the clinical efficacy of pricking-medicinal cupping bloodletting therapy for knee osteoarthritis.MethodSixty patients with knee osteoarthritis were randomly allocated to pricking-cupping bloodletting (treatment) and conventional treatment (control) groups, 30 cases each. In the treatment group, specific points around the knee were pricked with bloodletting needles and blood was removed by cupping with decoction. In the control group, the same points were given acupuncture and the affected part was given microwave treatment. The WOMAC score was recorded in the two groups of patients before treatment and after the end of treatment course. The therapeutic effect was evaluated by comparing the pre-and post-treatment scores between the two groups.ResultThere was a statistically significant pre-/post-treatment difference in the WOMAC total score in the two groups (P<0.01). The range of decrease in the WOMAC total score was significantly larger in the treatment group than in the control group. There was a statistically significant post-treatment difference in the WOMAC total score between the two groups (P<0.01). The WOMAC item scores decreased in varying degrees in both groups after treatment (P<0.01). The total efficacy rate was statistically higher in the treatment group than in the control group; there was a statistically significantdifference (P<0.05). The clinical therapeutic effect was statistically better in the treatment group than in the control group.Conclusion Pricking-medicinal cupping bloodletting is statistically better than conventional treatment in treating knee osteoarthritis. It can effectively relieve the pain and stiffness and improve knee function and the quality of life in the patients.

Objective To explore the role of OAZ gene in the pathogenesis of systemic lupus erythe-matosus (SLE) by using RNA interfering technique. Methods Peripheral blood mononuclear cells (PBMC) from SLE patients were collected. Each sample was equally divided into four groups for cell culture in 96 well plates. Specific siRNA for OAZ and GAPDH were concordantly added to the experimental group and the positive control group, while nonspecific siRNA was added to the negative control group and only culture medium was added to the Mock control group. Cells and supernatants were harvested after culturing for 72 hours, then RNA was extracted and reverse transcripted to cDNA. OAZ, Id1, Id2, Id3, Id4 mRNA expression levels were analyzed by using real-time PCR. Levels of IFN-γ, IL-4, IL-10, IL-12, IL-21, CCL2, ANA in the supernatant were tested by ELISA. Relationships between the expression levels of OAZ mRNA with levels of cytokines and ANA were analyzed. Results OAZ, Id1, Id2, Id3 gene mRNA expression levels (△Ct: 12.5±1.4, 8.9±1.5, 4.3±0.8, 8.04±1.1) in the experimental group were significantly decreased comparing to those in the negative control group (△Ct: 10.2±1.1, 6.5±1.2, 2.4±1.3, 6.2±1.2 respectively, P<0.05). Levels of IFN-γ, IL-10, IL-12, IL-21 and ANA in the experimental group were significantly lower than those in the negative control group (P< 0.05), but level of CCL2 was higher than the negative control group (P<0.05). Difference of OAZ mRNA expression levels (△△Ct) between the experimental group and the negative control group was negatively correlated with changes of ANA, IL-21 levels, but positively correlated with changes of Th1/Th2, CCL2. Conclusion OAZ siRNA can effectively reduce the expression of genes involved in the OAZ signaling pathway in SLE. OAZ may lead to abnormal production of ANA via regulating Id genes and cytokines.

Objective To investigate the efficacy of umbilical cord mesenchymal stem cells (UC-MSCs) transplantation in the treatment of the MRL/lpr mice. Methods Twenty four 18-week-old MRL/lpr female mice were divided into 3 groups:group 1 (G1) were transplanted with 1×106 UC- MSCs through caudal vein, group 2 (G2) were transplanted with 1×106 UC- MSCs three times and group 3 (G3) were treated with 0.5 ml normal saline as controls. Enzyme linked immunosorbent assay (ELISA) was used to measure the levels of serum anti-dsDNA antibodies. Twenty-four hours proteinuria and body weight were assessed every two weeks. The histopathology changes of the kidneys and lungs were observed. Results ① At the 25th weeks, the 24 hours proteinuria in group G1 (2.3±1.9) mg and G2 (1.8±1.4) mg was decreased than that in the control group (3.8±2.1) mg (P<0.05), and at the 27th weeks, that of groups G1 (2.5±1.5) mg and G2 (1.9±1.2) mg was also significantly decreased than in the control group (5.4±2.4) mg (P<0.01); ② From the 24th week, the body weight of groups G1 and G2 increased significantly than that of the control group (P< 0.05). At week 29, serum creatinine decreased significantly in both groups G1 (7.2±3.2) μmol/L and G2 (6.2±2.8) μmol/L than in the control group (12.5±2.3 ) μmol/L (P<0.05); ③One week after transplantation, the levels of anti-dsDNA antibodies in group G1 (46±11)×102 U/ml and G2(49×43)×102 U/ml were bothsignificantly decreased than those of the control groups (99±42)×102 U/ml (P<0.05) and the difference between group G2 (36±15)×102 U/ml and the controls (68±32)×102 U/ml was statistically significant; ④The nephron crescent formation in group G1 (0.12±0.07) and G2 (0.08±0.02) was significantly lower that of the control group (0.20±0.06) (P<0.05) and that of group G2 was significantly less that of froup G1 (P<0.05); ⑤ The interstitial pneumonitis was singnificantly milder in group G1 than group G2. Conclusions UC- MSCs is very effective in treating MRL/lpr mice. It is safe and free of rejection reactions.

Objective Among the factors affecting embryo implantation, oxidative stress is one that receives much medical attention. The purpose of the study was to explore the effect of H2 O2 on the endometrial stromal cells ( ESCs) in the decidual mouse model of oxidative stress of ESCs. Methods Primary ESCs cultured by enzymatic digestion with a mesh filter were divided into a control, an experimental, and a model group. Decidualization was induced in the mice of the experimental and model groups by inter-vention with 10 nM E2 and 1μmol/L P4 for 72 h in vitro. Then, the animals of the model group were treated with different concentra-tions of H2 O2 for 4 hours. The primary ESCs were identified by immunohistochemistry, the expression of dPRP mRNA determined byRT-PCR, the proliferation of the decidual ESCs treated with H2 O2 analyzed by CCK-8, and the level of ROS detected by flow cytometry. Results Primary mouse ESCs were successfully isolated, cultured, and identified, which were shaped like spindles and polygons, radial-ly aligned under the microscope. Immunofluorescence analysis showed positive expression of vimentin and negative expression of cytokeratin. The purity of the primary mouse ESCs was ( 96. 3 ± 0. 49 )%. Theexpression of dPRP mRNA was significantly higher in the ESCs treated with E2 and P4 than in the control (0.0002±0.0000 vs 1.0010±0.0011, P<0.01). H2O2 at ≥150μmol/L suppressed the proliferation of the decidual ESCs by 6.9% (P<0.05), and in a concen-tration-dependent manner, reaching the maximum inhibition rate of 70.6% at the concentration of 300μmol/L. The level of intracellular ROS was markedly increased in the ESCs treated with H2O2 at 50μmol/L (27.77±4.20) and 100μmol/L (43.57±6.58), with statisti-cally significant difference from that in the control group (17.47±0.61) (P=0.001). Conclusion H2O2 at 100μmol/L can signifi-cantly elevate the intracellar ROS level without affecting the proliferation of decidual primary ESCs, and therefore can be used for estab-lishing the model of oxidative stress of ESCs in decidual mice.
