OBJECTIVE: Background: We detect the effects of Beclinl on paclitaxel-sensitivity in laryngeal carcinoma cell. METHOD: This study used Hep-2, Hep-2-pcDNA3. 1, Hep-2-Beclinl as invitro model. The effect of paclitaxel on the proliferation and cell apoptosis of laryngeal cancer cell lines was evaluated by MTT assay and flow cytometry. The protein expression level of Akt and p-Akt was detected by Western blot. Result: After treated by paclitaxel, the inhibition rate was significantly higher in Hep-2-Beclin cells than in Hep-2-pcDNA3. 1 cells and Hep-2 cells (P<. 05). After dealing with 10 tg/L paclitaxel, the apoptosis rate in Hep-2, Hep-2-pcDNA3. 1, Hep-2-Beclinl were (23. 75 ± 2 3. 77) %, (21. 25 ± 4. 92) %, (32. 50 ± 5. 97) %, respectively. After dealing with 20µg/L paclitaxel, the apoptosis rate in Hep-2, Hep-2-pcDNA3. 1, Hep-2-Beclinl were (38. 75 ± 4. 79) %, (38. 75±6. 55) %, (50. 00±7. 26) %, respectively. Paclitaxel-induced apoptosis was higher in Hep-2-Beclin cells than in Hep-2-pcDNA3. 1 cells and Hep-2 cells (P<. 05). The result of western blot showed that the protein expression level of p-Akt in Hep-2-Beclin cells was lower than in Hep-2-pcDNA3. 1 cells and Hep-2 cells (P<0. 05) and the protein expression level of Akt was similar in three cell lines (P>0. 05). CONCLUSION Beclinl enhances paclitaxel-sensitivity by inhibition of PI3K/Akt pathway.

BACKGROUND: Matrix metal oproteinase inhibitor 1 plays an important role in the inhibition of articular cartilage degeneration and destruction.
OBJECTIVE: To observe the changes of matrix metal oproteinase inhibitor 1 expression level in synovium of knee osteoarthritis rats after treated with penetration needling of long needle.
METHODS: A total of 40 Sprague-Dawley rats were randomly assigned into normal group, penetration needling group, drug group and model group, with 10 rats in every group. 1.6% papain solution was injected into knee joint cavity of Sprague-Dawley rats. 2 weeks later, knee osteoarthritis models were established. Rats in the normal and model groups did not receive any intervention. In the penetration needling group, rats were treated by penetration needling with 0.3 mm×125.0 mm filiform needle. Rats in the drug group were intraarticularly injected with sodium hyaluronate.
RESULTS AND CONCLUSION: (1) Enzyme linked immunosorbent assay: at 4 weeks after treatment, matrix metal oproteinase inhibitor 1 expression in synovial membrane was higher in the normal group than in the model group (P < 0.05). Matrix metal oproteinase inhibitor 1 expression in synovial membrane was higher in the penetration needling group and drug group than in the model group (P < 0.05). (2) Results verified that long needle penetration therapy can effectively increase matrix metal oproteinase inhibitor 1 expression in synovial membrane of knee osteoarthritis model rats.

In the study of T2DM(n=30),IGR(n=26) and NGT(n=30) cases in Guangxi Province,T2DM had higher resistin and PAI-1 levels than did the groups of IGR and NGT(P<0.05).IGR had higher levels of PAI-1 and leptin than NGT(P<0.05).Leptin level of T2DM was higher than that of NGT(P<0.05).Insulin resistance index was positively correlated with leptin,TG and PAI-1 levels(P<0.05).

Objective: To observe the effect of treatment for proliferative knee osteoarthritis (KOA) using combined acupuncture and medicated compression. Method: All 328 cases were randomized into an observation and control group, 164 cases in each. Combined acupuncture and medicated compression were adopted in the observation group, while oral administration of Zhui Feng Tou Gu Wan (Wind-removing and Bone-penetrating Pills) were adopted in the control group. The clinical effects in the two groups were evaluated 40 days after the treatment. Result: There were significant differences in both marked and total effective rates (P<0.05). Conclusion: Combined acupuncture and medicated compression can obtain better effect for KOA than oral administration of the Wind-Removing and Bone-Penetrating pills.

Objective To review and analyze the sexual function of patients with spinal fractures complicated by incomplete paraparesis. Methods A total of 73 patients with incomplete paraparesis resulted from spinal fractures were retrospectively analyzed. Frankel Grade was used to determine the neurologic function and international index of ecrectile function (IIEF) to evaluate patients' sexual function. The patients with sexual dysfunction also were examined for reflex erection and psychogenic erection function. Results There were 21 patients with sexual dysfunction. Through ?2 test, significant difference was found between Frankel grade B and grade C as well as between grade D and grade E (P

BACKGROUND: Electro-acupuncture therapy shows good central and peripheral analgesic effects. Several studies have shown that transforming growth factor β (TGF-β) plays an important role in the pathogenesis of knee osteoarthritis. OBJECTIVE: To investigate the mechanism underlying electro-acupuncture treatment of knee osteoarthritis. METHODS: A total of 80 healthy male 3-month-old Sprague Dawley rats were randomly and evenly divided into normal, model, electro-acupuncture and drug groups. Rat models of knee osteoarthris were estbalished by ligating the femoral veins and forcing rats to do activies. At 1 month after knee osteoarthris induction, the electro-acupuncture group rats received electro-acupuncture therapy at two acupoints Neixiyan (EX-LE4) and Dubi (ST 35) with a depth of 0.1 cun (pulse 2 Hz, 20 minutes, once a day). The drug group rats were intraarticularly administerd sodium hyaluronate (0.1 mL/administration, once a week). After 2-week treatment, synovial tissue of the knee joint was harvested to determine the exprssion of TGF-β1, TGF-β1 receptor Ⅰand TGF-β1 receptor Ⅱ. RESULTS AND CONCLUSION: TGF-β1 expression in synovial tissue of the knee joint was significantly increased after knee osteoarthris (P < 0.05), but after electro-accupuncture therepy or sodium hyaluronate treatment, TGF-β1 expression was significantly decreased (P < 0.05), moreover, TGF-β1 receptor Ⅰ, Ⅱ expression was signficantly decreased (P < 0.05). These findings suggest that electro-acupuncture for treatment of knee osteoartheis improves the symptoms of osteoarthris by downregulating TGF-β1 expression, and reduction in TGF-β1 receptor Ⅰ, Ⅱ expression promotes the recovery of knee osteoarthris.

Objective:To evaluate the validity and reliability of adapted simplified Chinese Version of the Scoliosis Research Society-22(SRS-22)questionnaire.Methods:The English version of the SRS-22 was translated into simplified Chinese and was subjected to cross-culture adaptation;the final version of the simplified Chinese SRS-22 questionnaire was a consensus reached by an expert committee.Then the simplified Chinese version SRS-22 questionnaire and 36-Item Short Form Health Survey(MOS SF-36)questionnaire were used to survey 87 patients with adolescent idiopathic scoliosis who had been surgically treated;63 patients(72.4%)responded to the SRS-22 questionnaire.The average age of these patients(6 male,57 female)was(17.7?3.1)years(range,14.3-23.8 years).Fifty-six of the 63 patients returned the MOS SF-36 questionnaire.The 2 indicators of reliability were Cronbach's ? of internal consistency and intraclass correlation coefficient(ICC).Concurrent validity of the SRS-22 questionnaire was measured by comparing with domains of the SF-36 questionnaire,which was reflected by Pearson correlation coefficient(r).Results:The Cronbach ? values for 4 domains(function/activity,pain,self-image/appearance,and mental health)were all higher than 0.7;and the Cronbach ? value for satisfaction of management domain was acceptable.The intraclass correlation coefficients for function/activity,pain,self-image/appearance,mental health,and satisfaction domain were 0.74,0.78,0.86,0.81 and 0.84,respectively,demonstrating a satisfactory reproducibility.For the concurrent validity,3 domains had excellent correlation,10 had good correlation,and 21 had moderate correlation.Conclusion:The adapted simplified Chinese Version of the SRS-22 questionnaire has satisfactory reliability and concurrent validity,and might be suitable for post-operation clinical evaluation of Chinese adolescent patients with scoliosis.
