1.Femoral head replacement and clover titanium plate fixation in the repair of unstable intertrochanteric fractures in elderly patients
Chinese Journal of Tissue Engineering Research 2015;(22):3491-3495
BACKGROUND:The unstable intertrochanteric fractures are common in the elderly patients. Artificial femoral head replacement is a common treatment method, and different ways can be selected for reconstruction. OBJECTIVE:To explore the clinical effect of femoral head replacement combined with clover titanium plate fixation for unstable intertrochanteric fractures of the elderly. METHODS:A retrospective analysis was performed in 64 elderly patients with unstable intertrochanteric bone in the Jiangyou 903 Hospital from December 2011 to December 2012. They were given femoral head replacement treatment, and were divided into control group (32 cases) and experimental group (32 cases) according to reconstruction method. They received steel wire tension band and reconstruction and clover titanium plate fixation. RESULTS AND CONCLUSION:There were no significant differences in operation time and bleeding volume in operation process, postoperative recovery time of joint activities, time of out-of-bed activity, and bone calus formation time between the two groups (P > 0.05). However, compared with the control group, therapeutic effect was better and the incidence of complications was low in the experimental group (P < 0.05). These data suggest that femoral head replacement combined with the implementation of clover titanium plate fixation treatment can obtain good results for treatment of unstable intertrochanteric fracture in elderly patients.

4.Action mechanism for effects of tibial rotational alignment technique on patellofemoral joint biomechanics
Chinese Journal of Tissue Engineering Research 2016;20(22):3301-3307
BACKGROUND:At present, the placement of tibial anatomic landmarks has no gold standard during total knee arthroplasty. In order to achieve the most ideal rotation function of the tibial prosthesis, we should do the preparation before surgery, understand tibial rotational alignment to rationaly select and apply the prosthesis.
OBJECTIVE:To investigate the effect of tibial rotational alignment technique on patelofemoral joint biomechanics and related mechanisms.
METHODS:Ten pairs of human knee joint specimens were colected to prepare experimental platform. Specimens were fixed on the experiment frame, which was fixed on the material testing instrument for mechanics experiment. Weset different knee flexion angles, including 30°, 60°, 90° and 120°. Joint replacement was performed with the knee prosthesis. Samples were randomly assigned to two groups (n=5). Tibial nodule technology and ROM technology were used to identify rotationalalignment of the tibial prosthesis. The medial and lateral patelofemoral joint contact pressure peak and patelofemoral contact area at different knee angles, and the medial and lateral parts of patelofemoral contact area at deep knee angles were observed in both groups.
RESULTS AND CONCLUSION:(1) During flexion angle from 30° to 60°, the peak contact pressure of medial patelofemoral joint increased, and decreased gradualy in both groups. At flexion angle of 90°, contact pressure reached the minimum value, then increased gradualy, and reached the maximum value at 120°. No significant difference in peak contact pressure of medial patelofemoral joint at different knee angles was detected between the two groups (alP> 0.05). (2) During flexion angle from 30° to 60°, peak contact pressure of lateral patelofemoral joint decreased constantly, and then gradualy increased. No significant difference in peak contact pressure of lateral patelofemoral joint at different knee angles was detectable between thetwo groups (alP> 0.05). (3) During flexion angle from 30° to 60°, patelofemoral contact area decreased, and then increased gradualy in both groups. No significant difference in patelofemoral contact area at different knee angles was identified between the two groups (alP> 0.05). (4) At 90° and 120°, no significant difference in the area of medial and lateral contact parts was determined between the two groups (alP> 0.05). (5) Experimental results showed that tibial nodule technology and ROM technology for identifying tibial rotational alignment during total knee arthroplasty can obtain considerable biomechanical effects of patelofemoral joint.

8.Chinese urban norm for screening anxiety related emotional disorders in children
Chinese Journal of Tissue Engineering Research 2005;9(4):254-256
BACKGROUND:In China there is no norm to assess anxiety disorders in children.The Chinese urban norm for screening child anxiety related emotional disorders is applicable to assessing anxiety problem in Chinese children and assisting clinical diagnosis,research and epidemiological investigation. OBJECTIVE:To develop the norm for screening child anxiety related emotional disorders(SCARED) in Chinese cities,and test the reliability and validity of this scale. DESIGN:A sampling survey taking the students of Grade 2 and up in elementary schools and junior middle schools in 14 big and medium sized cities in China and children with anxiety disorders who visited children's mental clinics in Changsha,Jinan and Shenzhen cities from October 2001 to April 2002,as the subjects. SETTING:The psychiatric department of a provincial specialized mental hospital. PARTICIPANTS:A total of 2 019 subjects(1 012 males and 1 007 females) with the mean age of(11± 2) years old were selected from 14 cities in China(Beijing,Tianjin,Taiyuan,Siping,Wuhan, Changsha,Xi'an,Shenzhen,Mianyang,Jinan,Fuzhou and Yichun) from October 2001 to April 2002.The students and their parents(norm group) filled in SCARED,and meanwhile,90 children with anxiety disorders who visited children's mental clinics in Changsha, Jinan and Shenzhen were taken as anxiety group. INTERVENTIONS:The children completed one copy of SCARED in the classroom during regular classes after informed consent was obtained, and then the questionnaires were collected on the spot. Another copy of SCARED was taken home by the children to be completed by the parents.Meanwhile,in Changsha,the parents filled in the child behavior checklist(CBCL) while their children completed the Piers Harris children's self concept scale(PHCSS).The reliability and validity of SCARED were determined. MAIN OUTCOME MEASURES:Reliability and validity of SCARED. RESULTS:The test retest coefficients of SCARED ranged from 0.567 to 0.608,split reliability of SCARED was 0.88,and Cronbach alpha(α ) coefficients were 0.43 to 0.89,with good reliability. Significant correlations were found between the total scores and anxiety indexes of SCARED and Achenbach CBCL(r=0.564,0.603,P< 0.05).The children in anxiety group scored higher in SCARED than those in norm group(t=8.06 to 12.89,P=0.000). Sensitivity and specificity of diagnosis of anxiety disorder were 0.74 and 0.79,respectively. CONCLUSION:The reliability and validity of SCARED are good, suggesting that the norm is applicable to assessing anxiety disorders in Chinese children.
9.Role of autophagy in carinogenesis and tumor therapy
Journal of International Oncology 2008;35(5):348-351
Autophagy is a kind of ubiquitous physiological mechanism in normal and abnormal cells.Autophagy plays a key role in protein equilibrium and cleaning impaired organelle to maintain homeostasis in cells.It plays different roles at different stages of carcinogenesis by promoting tumor development or inhibiting tumor growth.It has potential applications for tumor therapy by up-regulating or down-regulating the level of au-tophagy in tumor cells.
10.Development of Novel Antiviral Therapies for Hepatitis C Virus
Virologica Sinica 2010;25(4):246-266
Over 170 million people worldwide are infected with hepatitis C virus (HCV), a major cause of liver diseases. Current interferon-based therapy is of limited efficacy and has significant side effects and more effective and better tolerated therapies are urgently needed. HCV is a positive, single-stranded RNA virus with a 9.6 kb genome that encodes ten viral proteins. Among them, the NS3 protease and the NSSB polymerase are essential for viral replication and have been the main focus of drug discovery efforts. Aided by structure-based drug design,potent and specific inhibitors of NS3 and NSSB have been identified, some of which are in late stage clinical trials and may significantly improve current HCV treatment. Inhibitors of other viral targets such as NSSA are also being pursued. However, HCV is an RNA virus characterized by high replication and mutation rates and consequently, resistance emerges quickly in patients treated with specific antivirals as monotherapy. A complementary approach is to target host factors such as cyclophilins that are also essential for viral replication and may present a higher genetic barrier to resistance. Combinations of these inhibitors of different mechanism are likely to become the essential components of future HCV therapies in order to maximize antiviral efficacy and prevent the emergence of resistance.
