3.Advances on biomechanics and kinematics of sprain of ankle joint.
China Journal of Orthopaedics and Traumatology 2015;28(4):374-377
Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.

6.Clinical analysis of 190 patients with myomectomy by laparoscope
Chinese Journal of Primary Medicine and Pharmacy 2015;(7):1023-1025
Objective To investigate the clinical effect of laparoscopic operation and laparotomy in the treat-ment of uterine fibroids.Methods A retrospective analysis of uterine fibroids and requests to retain the clinical data of 380 cases of uterine of patients,according to treatment methods,they were divided into laparoscopic myomectomy group (group A)and cesarean section uterine fibroids removed surgery group (B group),there were 190 cases,two groups of patients,surgery,clinical effect were analyzed.Results In group A,operation time,postoperative exhaust time,postoperative ambulation time,postoperative VAS score,duration of hospitalization,injection of analgesics appli-cation proportion were (96 ±35)min,(24 ±8.5)h,(12 ±4)h,(2.0 ±1.5),(4.0 ±1.2)d,17.8%,patients in the group B respectively (98 ±28)min,(40 ±12)h,(20 ±8)h,(6.0 ±1.3),(8 ±2)d,84.6% there was a significant differences between the two groups (t=-2.558,33.96,45.810,50.571,34.120,χ2 =169.89,all P<0.05);group A and group B,the amount of bleeding were (186 ±78)mL and (175 ±85)mL,with no significant difference between the two groups (t=1.911,P>0.05);group A,the complication rate was 7.34%,lower than the 12.6%in the group B,there was significant difference between the two groups (χ2 =3.923,P<0.05).Conclusion Laparoscopic myo-mectomy in treatment of uterine fibroids,good effect,less trauma,quicker recovery,shorter hospitalization time of patients,should be further popularized in clinic.
7.Percutaneous AO Kirschner wire plus tension band wire fixation for patella closed transverse fracture
Chinese Journal of Tissue Engineering Research 2007;11(36):7317-7320
BACKGROUND: Tension band suture fixation is always used in treating patellar fracture, and its modified method of Kirschner wire plus tension band steel-wire is also widely applied. But because the traditional surgery always causes massive incision and scar formation, it affects the appearance and function of knee joint.OBJECTIVE: To investigate the clinical curative effect of percutaneous puncture plus tension zone steel-wire fixation for the treatment of patella closed transverse fracture.DESIGN: Retrospective analysis:SETTING: Second Hospital of Medical College, Xi'an Jiaotong University.PARTICIPANTS: Twenty-nine patients with closed patellar transverse fracture admitted by Department of Orthopedics,Medical College of Xi'an Jiaotong University were selected from an average age of 36 years old. Only people that were diagnosed by X-ray as closed patellar transverse fracture were enrolled, and the informed consent was obtained from them.jostled until resetting, and then the fractured pieces were clamped by a clavical clamp to fix. Two incisions were made at the upper and lower ends of patella, and two were penetrated from the incision until its tip out of the lower hole of the same Kirschner wire under skin. The soft steel wire was drawn tightly and bended along the tip of Kirschner wire. The three-grading method, and the recovery of patients in 4 years after operation was evaluated according to the composite evaluation means about the knee joint established by Xu et al (pain, movement range of knee joint and reset of the fracture in patellar face. Meanwhile, the postoperative complications were observed.MAIN OUTCOME MEASURES: Wound healing, postoperative functional recovery and complications of patients.cases scored in grade 1, accounted for 93%, 2 cases in grade 2, accounted for 7%, who were recovered after change of means about the knee joint established by Xu, 26 cases were excellent, and 3 were good; in the movement range of knee joint, 27 cases were excellent and 2 were good; in the resetting of fracture, 26 cases were excellent and 3 were infection, traumatic arthritis, or other complications were found in patients.CONCLUSION: Percutaneous internal fixation with Kirchner needles combined with tension band wires for treatment of closed patella transverse fractures is featured by minimal trauma, fast recovery and beautiful outlook in the operative area. Moreover, it permits early movement in the knee joints. This method has a satisfied clinical curative effect.
8.New progress of the research on the DNA methyltransferases in the pathogenesis of carcinoma
Practical Oncology Journal 2014;(1):75-80
DNA methylation is the main profile of epigenetics .DNA methyltransferases ( DNMTs) is the main regulatory enzyme during DNA methylation .The activation of DNMTs ,the hypermethylation and low expres-sion of some tumor suppressor genes are involved in the carcinogenesis and development of various human canc -ers,which is a biomarker of poor prognosis .Both of the polymorphism of DNA methyltransferases ( DNMT3b) and tobacco smoking are risk factors of tumorgenesis .The targeted therapy of DNMTs is very popular due to its low cy-totoxity.This review will focus on new progress of the research on DNMTs in pathogenesis of carcinoma .
9.Effect of Acupuncture on Anxiety and Depression Due to Vertebrobasilar Insufficient Vertigo
Shanghai Journal of Acupuncture and Moxibustion 2016;35(3):282-283
Objective To observe the clinical efficacy of acupuncture in treating anxiety and depression due to vertebrobasilar insufficient vertigo (VBIV).Method Eighty-two patients with anxiety and depression due to VBIV were randomized into a treatment group and a control group, 41 cases in each group. The control group was intervened by conventional medication, while the treatment group was by acupuncture in addition to the treatments given to the control group. The Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and Treatment Emergent Symptom Scale (TESS) were evaluated before and after intervention.Result The HAMA, HAMD, SAS, and SDS scores were significantly changed after intervention in both groups (P<0.05). After treatment, the HAMA score in the treatment group was significantly different from that in the control group (P<0.05). The TESS scores were significantly changed after treatment in both groups (P<0.01). After intervention, the TESS score in the treatment group was significantly different from that in the control group (P<0.01).Conclusion Acupuncture is an effective approach in treating anxiety and depression due to VBIV, and it can reduce the occurrence of adverse reactions.
10.Research on CT diagnostic analysis of three-dimensional magnetic palatal maxillary dentition direction
China Medical Equipment 2016;13(3):50-53
Objective:To discuss the changing position in three dimensions of maxillary dentition magnetic arch expansion after.Methods: Thirty patients who were in-patient cases were selected, and received three-dimensional data measured before and after treatment it its spiral CT, observed the three-dimensional position of maxillary dentition before and after treatment, and the angle of landmarks change data paired sign test for comparison.Results: Patients in the vertical position of maxillary dentition before and after treatment, sagittal and horizontal direction are changed. First premolars, first molars occurred cheek overall movement and dumping; the maxillary first premolar region is the largest widening position; three-dimensional position of the maxillary central incisor forward, the next move.Conclusion: Patients before and after the change of maxillary dentition MPE can be clearly presented in accordance with spiral CT, lay the foundation for further research MPE mechanism.
