BACKGROUND: The pathological changes of osteoarthritis are similar to that of kaschin-beck disease, but the cause of the latter is still unclear,damage is more serious. From the comparison of pathology changes between them, we hope to find out an effective therapeutic method with the assistance of arthroscope basing on the experiences in osteoarthritis.OBJECTIVE: To make comparison of the histomorphological changes between osteoarthritis and kaschin-beck disease with knee arthroscope,which give clues to the diagnosis and selection of operative technique for kaschin-bock disease under arthroscope.DESIGN: Case control study.SETTING: Department of Orthopaedics, Shaanxi People's Hospital.PARTICIPANTS: Thirty-five patients who needed arthroscope surgery due to severer knee osteoarthritis were randomly selected from Department of Orthopaedics, Shaanxi People's Hospital between April 1998 and September 2000; Meanwhile 31 patients with knee joint functional obstacle caused by kaschin-beck disease (epidemic disease area) were randomly selected from Luochuan Hospital of Shaanxi Province in November 2001.METHODS: Japanese made OLYMPUS series color television arthroscope and surgery system were used to carry out knee joint operations in all participants. During the operation, video recording, postoperative editing, photographs, comparison and analysis were conducted, in order to find out the pathological changes of the two groups in knee joint synovium, patella, femur, tibia and meniscus with the assistance of arthroscope.RESULTS: Totally 66 patients were enrolled in this study and all endamage in Kaschin-beck disease and osteoarthritis: Injuries were graded into grade 0, 1, 2 and 3, there were 0,3,5,23 cases and 0,3,16,16cases correspondingly in kaschin-beck disease group and osteoarthritis cartilage damage was presented by big piece of cartilage peeled off, part of them came off leading to bone exposure, the exposed bone surface is uneven; while cartilage damage in osteoarthritis was presented by the wear of cartilage, moreover cartilage island was found remained in the exposed bone with the surface covered with fiber strips and the exposed observed in 24 patients with Kaschin-beck disease, 5 cases with coarse stress point and 19 cases with burr-like damage, amongst which there were 9 cases displayed both medial and lateral meniscus damages; in osteoarthritis group there were 16 cases showed meniscus damages including edge wears in11 cases and breakage in 5 cases.CONCLUSION: Cartilage damage in knee articular was obviously severer in Kaschin-beck disease than in osteoarthritis, although kaschin-beck disease is no matter resulting in serious knee joint damage, but its pathology changes are different from osteoarthritis, we should pay more attention to the peculiarity of big piece of cartilage peeling off during operations.

Thirty seven patients with venous thromboembolic disease in puerperium were admitted to hospital from January 2005 to December 2008; the clinical data of patients were retrospectively analyzed.The average age of patients was (33 ± 6)years (21 -42 years); the average onset time was ( 10 ± 6) d( 1 -50 d) after delivery.Seven patients had vaginal birth and 30 by cesarean section.The risk factors included pregnancy,cesarean section,age,infection,thrombophilia.All were diagnosed by ultrasonography and treated by anticoagulant,antiplatelet and thrombolytic therapy in the acute phase,followed by wearing elastic compressive stockings for more than 2 years.Pulmonary embolism was diagnosed in 8 patients by CT angiography,in 7 of whom inferior vena cava filter was administrated emergently.The patients were followed up for (29 ± 10)months ( 12 -60 months); during the follow-up 3 developed deep vein post-thrombosis syndrome,while others kept in good condition.The results indicate that initial anticoagulant,antiplatelet and thrombolytic therapy followed by elastic compressive stockings administration is effective for venous thromboembolic disease during puerperium.

Objective: To explore the effect of suberoylanilide hydroxamic acid (SAHA) improving cardiac hypertrophy via inhibiting histone deacetylases (HDAC) in experimental mice and to provide a new idea for prevention and treatment of cardiac hypertrophy. Methods: Cardiac hypertrophy mice model was established by thoracic aorta ligation. A total of 60 Kunming mice were randomly divided into 4 groups: Normal control group, Sham operation group, Cardiac hypertrophy (CH) group and CH+SAHA group. There were 6 mice used in each group. Myocardial cell morphology was observed by HE staining, cardiac function was assessed by echocardiography, mRNA and protein expressions of HDAC5 (the isoform of HDAC) and β-MHC were examined by RT-PCR and Western blot analysis. Results: The mice in CH group had myocardial cell hypertrophy, disordered arrangement and hyperchromatic nucleus. Compared with Sham operation group, CH group showed decreased left ventricular end diastolic diameter (LVEDD), left ventricular end diastolic volume (LVEDV) and increased thickness of inter-ventricular septum (IVS), allP<0.05; CH group presented elevated mRNA and protein expressions of HDAC5 and β-MHC,P<0.05. SAHA obviously decreased HDAC5 expression, down regulated cardiac hypertrophy related β-MHC gene expression, improved cardiac function and hypertrophy, all P<0.05. Conclusion: HDAC were involved in myocardial hypertrophy; SAHA could inhibit HDAC expression and therefore,improved myocardial hypertrophy in experimental mice.

Herpes simplex virus type Ⅰ(HSV-1) is a common pathogen, and human is the only natural host of it.Following a period of lytic replication in epithelial cells, HSV-1 enters axon terminals of sensory neurons and then travels via retrograde transport to the sensory ganglia where latency can be established.Upon the stimulation of some stressors, the latent virus can reactivate, leading to recurrent diseases.Therefore, to clarify the mechanism of HSV-1 latent infection and stress-induced reactivation will offer new insights into the prevention, treatment and control of HSV-1 infection.In this review, we describes the mechanisms underlying HSV-1 latent infection and stress-induced reactivation.

Objective To explore the feasibility of team-based learning (TBL) for practice teaching of the aerospace nutrition and food hygiene.Methods A total of 90 students were investigated,and were divided into the TBL group (n=46) and the TL group (n=44) by simple random sampling.After the experiment teaching,a test and questionnaire were used to compare the teaching effect of TBL group and TL group.SPSS 18.0 was used for date and the data was analyzed by Independent-Samples t test and Chi-square test.Results Students in TBL group achieved higher mean test scores (85.70 ± 3.47) compared with students (74.10±2.41) in TL group and the difference was statistically significant (t=8.703,P=0.000).The results of the questionnaire showed that,compared with the TL group,TBL group students more agreed with the positive impact of the teaching methods on their team work ability,interpersonal skills,communication ability,problem-solving and self-learning and other aspects,and the differences between two groups were statistically significant (P＜0.05).In addition,the majority of the respondents in TBL group [93.5％ (43/46)] were satisfied with TBL.Conclusions TBL teaching is better than the TL teaching,and it can significantly improve students' comprehension of knowledge and enhance their learning effect.

Objective To summarize experience of concomitant endovascular aneurysm aortic repair(EVAR) and coronary artery bypass grafting(CABG) for patients of severe coronary artery disease(CAD) complicated with infra-renal abdominal aortic aneurysm(AAA) or infra-renal abdominal penetrating aortic ulcer(PAU).Methods Between January 2013 and December 2016,13 patients with severe CAD and infra-renal AAA/PAU who underwent CABG and EVAR were enrolled in this study.12 patients (92.3 ％) were male and 1 patient was female (7.7 ％),the mean age of(63.7 ± 7.3) years.11 patients with CAD related symptoms,2 patients with AAA/PAU related symptoms,abdominal aortic lesions include:AAA in 3cases,PAU in 10 cases,2 patients combined with PAU of the thoracic aorta.CABG and EVAR manipulations were performed according to the routine protocol,patients who were combined with thoracic aorta PAU were treated with thoracic endovascular aortic repair (TEVAR) simultaneously.Results 7 patients received EVAR followed by CABG;6 patients received CABG followed by EVAR,TEVAR were performed in 2 patients.For all the patients,there were 11 cases of CABG were performed under the cardiopulmonary bypass(CPB) (ON-PUMP) and 2 others cases were performed without CPB(OFF-PUMP).On the average(2.5 ± 0.7)grafts were performed.The time of aortic clamp and CPB averaged were(50.7 ± 16.5)min and (58.0 ± 11.2)min respectively for the ON-PUMP CABG patients.Totally 30 thoracic aorta and abdominal aorta stent grafts were implanted in 13 patients.The duration of postoperative mechanical ventilation time was (17.8 ± 7.0) hours,Median intensive care stay was (2.7 ± 1.9) days,while hospital stay was(8.1 ± 2.4)days.All the patients was discharged.1 patient suffered wound unhealing 2 days after discharging,followed by sternal infection,he was re-admitted and received pectoralis major myocutaneous flap transfer operation,29 days after this operation,he suffered sudden cardiac arrest and eventually dead.The other 12 surviving patients was followed up for 1 ～ 36 months,The results showed that the patency of the grafts in all patients was good,no EVAR related secondary interventions were required.Conclusion For the patients with surgical indications,the procedure of one stage CABG and EVAR completed by one surgical team was safe and feasible.Comparing with the traditional one stage or staged surgical repair,this strategy showed less surgical trauma,shorter operation time,lower perioperative risks,more efficacy and more conducive to the overall management of patients.

AIM:To study the effects of FK506 binding protein 12.6(FKBP12.6) overexpression on the performance of sarcoplasmic reticulum(SR) in ventricular myocytes of rats with heart failure.METHODS:The adenovirus(Ad)-mediated gene transfer was used to overexpress FKBP12.6 in ventricular myocytes of rats with heart failure.Western blotting and reverse transcriptase-polymerase chain reaction(RT-PCR) analysis were used to reveale specific overexpression of FKBP12.6.X-rhod-1-AM was used as the Ca2+ indicator,and cells were viewed under a confocal microscope.RESULTS:Adenovirus mediated overexpression of FKBP12.6 resulted in a 5-fold increase in relative FKBP12.6 mRNA levels and a 4-fold increase in relative FKBP12.6 protein levels at 48 h after transfection compared with control.The amplitude of the fluorescence [Ca2+]i transient was significantly increased in Ad-FKBP12.6-GFP cardiomyocytes compared with Ad-GFP myocytes(peak F/F0,3.16?0.42 vs 1.43?0.38,P
