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.

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.

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 clinical effects of pars repair by the pedicle screws,laminal hooks and auto iliac bone graft through the Wiltse approach via Quadrant channel for the treatment of the adolescent spodylolysis.Methods From November 2007 to April 2011,pars defects of 11 patients (10 males and 1 female) were repaired with pedicle screws,laminal hooks and auto iliac bone graft via Quadrant channel through the Wiltse approach.The mean age of 11 patients was 17.3 years (range 15-19).Mean course was 9.9 months (range 6-14 months).All patients have bilateral pars defect of L5.There was no poroma across the pars that have been proved by X-ray film and 3-D CT before the operation.There were 4 patients with Ⅰ grade spondylolisthesis.The degeneration of the intervertebral disc assessed by Pfirrmann grade of all patients was no more than Ⅰ grade.Visual analogue scale (VAS) and Oswestry disability index (ODI) were compared before and after operation.The fusion of pars defect was observed by X-ray film and 3-D CT.Results The mean operation time was 85.5±12.3 min (range 70-110 min); intraoperatve blood loss was 80-150 ml (mean 105 ± 19.4 ml).Two patients were lost in follow-up after operation and the others had been followed up for 12 to 24 months (mean 16 months).All patients had significant pain relief and function recovery after operation.Mean postoperative VAS score was 1.5± 1.0 compared with 4.5± 1.0 of preoperation (t=4.603,P=0.002).ODI was decreased from 49.3％± 14.2％ of preoperation to 12.0％±4.9％ of the last follow-up (t=7.344,P=0.000).With the Macnab grades,7 patients are excellent,2 patients are good.3-D CT showed that all pars defect were fused in the last follow-up.Conclusion Pars repair by the pedicle screws,laminal hooks and auto iliac bone graft through the Wiltse approach via Quadrant channel can protect the paravertebral muscle,relief patients from pain,and improve function.

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.
