Objective To observe the effects of intra-articular injection of sinomenine on morphology of synovium and cartilage as well as contents of MMP-13 and cartilage oligomeric matrix protein(COMP) in serum and synovial fluid of rabbit knee osteoarthritis model.Methods A total of 38 New Zealand white rabbits were randomly divided into 4 groups: control group, model group, hyaluronate group and sinomenine group. Model group, hyaluronate group and sinomenine group established knee osteoarthritis model by intra-articular injection of papain enzyme, and were treated with saline, sodium hyaluronate and sinomenine respectively except for control group. 5 weeks after treatment, all rabbits were sacrificed for HE staining and histological grading on cartilago articularis and synovium, and ELISA method was used to detect the contents of MMP-13 and COMP in rabbit serum and synovial fluid.Results Mankin's scores of articular cartilage and histological scores of synovium in model group were significantly higher than those of control group (P<0.01), and were markedly lower in sinomenine group than those of model group (P<0.01); the contents of MMP-13 and COMP in serum and synovial fluid of model group were significantly raised compared with control group (P<0.01), and were reduced obviously in sinomenine group compared with model group (P<0.05,P<0.01).Conclusion Intra-articular injection of sinomenine can reduce the levels of MMP-13 and COMP in serum and synovial fluid of rabbit knee osteoarthritis model, and improve synovial inflammation, as well as delay the degradation of articular cartilage.

Objective To compare the clinical application of endoscope system and dimensional disc hole mirror, and its advantages of percutaneous transforaminal endoscopic discectomy TESSY technology. Methods Two hundred and eighty patients with lumbar disc herniation randomly divided into foraminal mirror group and endoscopic group(140 cases for each groups). Patients in foraminal mirror group were given TESSY removal of nucleus pulposus through lateral approach road,while in endoscopic group were given posterior approach discectomy. The operation time,bleeding volume,postoperative time,incision length,waist and leg waist pain and functional recovery were recorded. Results The operation incision length in foraminal mirror group was(0. 8 ± 0. 1)mm,significantly shorter in the endoscopic group((1. 7 ± 0. 2)mm),the amount of bleeding in foraminal mirror group was( 9. 8 ± 4. 3 )ml,significantly less than the endoscopic group(( 78. 6 ± 18. 8)ml). The above data were statistically significant difference( t =21. 753,19. 280;P ﹤0. 01 ). The getting out of bed time after operation was(0. 3 ± 0. 1)d,significantly earlier than that in the endoscopic group ((3. 5 ± 0. 8)d;t=21. 451;P﹤0. 01). VAS scores of patients in two group at postoperative were(7. 4 ± 1. 8) and(7. 3 ± 1. 6),significantly decreased than that of preoperative((2. 7 ± 1. 7)and(2. 5 ± 1. 6);t=10. 259, 11. 465;P﹤0. 01),But there were no significant differences between the two groups before and after treatment ( P﹥ 0. 05 ). After treatment,waist function recovery in the two groups were 97. 1%( 136/140 ),95. 7%(134/140),and the difference was significant(χ2 =0. 415,P﹥0. 05). Conclusion Foraminal mirror TESSY technique in the treatment of lumbar disc herniation with microendoscopy discectomy with small incision is proved a good approach with less bleeding,postoperative early rehabilitation.

The Ebola virus belongs to the Filovirus family, which causes Ebola hemorrhagic fever (mortality, 25%-90%). An outbreak of infection by the Ebola virus is sweeping across West Africa, leading to high mortality and worldwide panic. The Ebola virus has caused a serious threat to public health, so intensive scientific studies have been carried out. Several vaccines (e.g., rVSV-ZEBOV, ChAd3-ZEBOV) have been put into clinical trials and antiviral drugs (e.g., TKM-Ebola, ZMAPP) have been administered in the emergency setting to patients infected by the Ebola virus. Here, recent advances in vaccines and drugs against the Ebola virus are reviewed.

Objective To observe the effects of intra-articular injection of sinomenine on the expressions of vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) in articular cartilage and synovium of rabbit knee osteoarthritis models; To discuss its mechanism of action. Methods Totally 40 New Zealand white rabbits were randomly divided into 4 groups: control group, model group, hyaluronate group and sinomenine group. Model group, hyaluronate group and sinomenine group established knee osteoarthritis model by using intra-articular injection of papain enzyme and were treated with saline, sodium hyaluronate and sinomenine respectively for 30 d, except for the control group. After treatment, method of immunohistochemistry was used to detect the expressions of VEGF and NGF in rabbit articular cartilage and synovium. Results Compared with the control group, the expressions of VEGF and NGF in articular cartilage and synovium of model group significantly increased (P<0.01); compared with the model group, the expressions of VEGF and NGF in articular cartilage and synovium of sinomenine group significantly decreased (P<0.05, P<0.01); the expressions of VEGF and NGF in articular cartilage and synovium in sinomenine group were lower than hyaluronate group (P<0.05, P<0.01). Conclusion Intra-articular injection of sinomenine can down-regulate the expressions of VEGF and NGF in articular cartilage and synovium of rabbit knee osteoarthritis.

Objective To analyse the rate of coincidence to suspected coronary artery disease (CAD) patient between positive exercise treadmill testing (TET) and coronary angiography (CAG) test.Method Two hundred and sixty-eight chest pain patients positive in TET were performed CAG test,coronary stenosis exceed 50% was diagnosed CAD. Results One hundred and seventy-six patients (65.67%) was diagnosed by CAG, 105 male and 71 female in them. Ninety-two (34.33%) patients was negative in CAG test. The false positive rate of TET between post-menopause patients (30.12%, 25/83 ) andmale patients (28.08%, 41/146) was no significant difference(P > 0.05 ); the difference of false positive rate between pro-menopause patients (66.67%, 26/39) and male patients (28.08% ,41/146) was statistical significance (P < 0.01 ). Conclusions The positive rate of CAG can be greatly improved by screening the chest pain patients though TET before CAG, if the positive in TET performed CAG only. TET false positive rate of pro-menopause female is significantly higher than post-menopause female or male.

Objective: To investigate the association between body mass index ( BMI ) and mortality risk among older Chinese based on the China Health and Retirement Longitudinal Study ( CHARLS ). Methods: The demographic features, BMI, prevalence of chronic diseases and mortality among the elderly at ages of 60 years and greater were captured from the CHARLS database from 2011 to 2018. A multivariable Cox proportional hazards regression model was used to examine the association between BMI and the risk of death. Results: Totally 6 023 subjects were enrolled, including 3 006 men ( 50.09% ) and 3 017 women ( 49.91% ), and 68.69% of the participants ( 4 137 subjects ) were at ages of 60 to 69 years. There were 637 subjects ( 10.58% ) with underweight, 1 544 ( 25.63% ) with overweight, and 557 ( 9.25% ) with obesity. During the follow-up period ( 35 091 person-years ), 1 035 subjects died. Multivariable Cox proportional hazards regression analysis revealed an increased risk of mortality among the underweight elderly ( HR=1.496, 95%CI: 1.261-1.775 ) and a reduced risk of mortality among the obese elderly ( HR=0.671, 95%CI: 0.511-0.881 ) relative to the elderly with normal weight, after adjustment for age, gender, smoking, household registration, administration of anti-diabetic drugs, administration of anti-dyslipidemia drugs, and administration of anti-hypertensive drugs. Conclusion It is found that the risk of mortality among the Chinese elderly correlatives with BMI through the analysis of CHARLS data.

As a part of acupuncture system, acupuncture anesthesia can promote the development of acupuncture theory.Muscle region is also a part of acupuncture system and plays a guiding role in clinical application of acupuncture anesthesia.The correlation between the distribution of muscle regions and nerves acts as the substantial foundation of the guiding role.At the same time, acupuncture anesthesia has been promoting the continuous development of muscle region theory.The cyclic development relation between the two (practice-theory-practice) is consistent with the dialectical development view.

Objective:To evaluate the relationship betweenparacardial adipose tissue (PAT) volume, body mass index (BMI) and severe coronary artery stenosis in young people by quantitative measurement of 256-slice spiral CT.
Methods: A total of 150 patients younger than 45 years and received coronary angiography (CAG) in our hospital were divided into 2 groups:Lesion group, the patients with severe main coronary branch stenosis and Control group, patients with normal coronary artery. n=75 in each group. The height, body weight and BMI were recorded in all patients;imaging data was uploaded to the workstation to calculate the volumes ofepicardiumadipose tissue (EAT) volume,pericardial outsideadipose tissue volume and PAT volume, the correlation among 3 parameters were analyzed respectively.
Results:Compared with Control group, Lesion group had increased BMI (28.169±2.203) kg/m2 vs (24.960±3.041) kg/m2 and PAT volume (178.676±3.041) ml vs (99.0616±3.041) ml, all P<0.05. Compared with Control group,no matter male or female, Lesion group had larger PAT volume, P<0.01.EAT volume was related to pericardial outside adipose tissue volume (r=0.837, P<0.001) and PAT volume (r=0.971, P<0.001);pericardial outside adipose tissue volume was related to PAT volume (r=0.944, P<0.001).
Conclusion:PAT volume and BMI were obviously correlated to severe coronary artery stenosis in young people.
