ABSTRACT
Objective To explore the clinical results of the arthroscopic acromioplasty in the rotator cuff repair.Methods Sixty-five patients (42 males and 23 females) to receive suture bridge repair under the arthroscopy between May 2012 and May 2014 were selected and randomly divided into an experimental group and a control group.The experimental group was given suture bridge repair with acromioplasty,while the control group underwent the suture bridge repair without acromioplasty.The time of operation was recorded.The range of motion (ROM) of the shoulder,the UCLA shoulder scoring system (ULCA) score,American orthopedic surgeon scoring system (ASES) score,the visual analogue scale (VAS) score and Constant score were observed 3 and 12 months after the operation.Results There were no significant differences in age,sex and the affected side between the two groups.Significant differences were found between the two groups in the duration of the operation (t=-18.5,P＜0.05).There were no significant differences in the ROM and the ULCA,ASES,VAS and constant scores of the shoulder 3 and 12 months after the operation.Conclusion No significant differences were found in the ROM and the shoulder function scoring between giving acromioplasty under the arthroscopy or not.However,the operation time of undergoing acromioplasty under the arthroscopy was longer.
ABSTRACT
BACKGROUND:To reduce the amount of bleeding and the amount of hemoglobin after total knee replacement has been a key project in the clinical research in the division of bone and joint. Currently, ice therapy has been widely used in the clinic for tissue sweling and pain due to various physical and chemical factors. OBJECTIVE:To investigate the risk factors of postoperative hemoglobin after total knee replacement and discuss the effects of ice intervention. METHODS: 240 patients with osteoarthritis based on the random draw principles were equaly divided into the treatment group and the control group. The general information, disease status, diagnosis and treatment and prognosis of the two groups were investigated. Al patients were actively subjected to artificial total knee replacement. On the basis of the treatment in the control group, the treatment group received ice intervention at 2 hours after replacement for 7 consecutive days. RESULTS AND CONCLUSION:The postoperative hemoglobin decrease occurred in 34 patients, with the incidence of 14.2% among 240 patients at 7 days after replacement. Multivariate logistic regression analysis results showed that age, no ice treatment, body mass index were the main risk factors for hemoglobin decrease after total knee replacement (P 0.05). Results verify that clinical application of total knee replacement facilitated the knee recovery in patients with osteoarthritis, but hemoglobin decrease and bleeding existed. Active ice intervention can reduce the risk and relieve postoperative pain.
ABSTRACT
Objective To study effect of a novel schiff base ruthenium coordination compound on cell proliferation and apoptosis of gastric cancer SGC-7901 cell.Method Gastric cancer SGC-7901 cell were divided into four groups according to different treatment of novel schiff base ruthenium coordination compound (concentration of 10, 30, 50μmol/L) and blank group with DMSO.Cell proliferation was detected by MTT assay, cell apoptosis and cell cycle were analysed by flow cytometry.ResuIts MTT results showed the inhibitory effect of novel schiff base ruthenium coordination compound on SGC-7901 cell enhanced with the increase of its concentration, and inhibitory rates were higher than that of blank group at 24, 48, 72 h.Flow cytometry results showed the apoptosis rate of novel ruthenium coordination compound groups of 10, 30, 50μmol/L were (17.64 ±1.21)%, (26.47 ± 0.61)%, (55.63 ±1.49)%, respectively, all higher than that of blank group (P<0.05).The cell proportion of G1 phase increased with the increasing of the novel schiff base ruthenium coordination.ConcIusion A novel schiff base ruthenium coordination compound could inhibit the growth of gastric cancer SGC-7901 cells, promote apoptosis and arrest gastric cancer SGC-7901 cells at G1.
ABSTRACT
Objective To observe the clinical effect of headless compression Screw (HCS)under arthroscope in the treat-ment of patella fracture.Methods Nineteen patients of patella transverse fractures were selected,all of them were treated with HCS fixation under arthroscope,reviewed and followed-up after surgery.Results X-ray examination after surgery of 3 -5 weeks found that the fracture lines blurred or disappeared,and the patella articular surface was smooth without displacement.The healing time of fracture was 8 weeks on average after operation;There was no statistical difference in the range of the knee joint in the af-fected side in (135.42±5.82)°and the contralateral side in (139.38±6.55)°(P >0.05);The knee Lysholm score of the last follow-up was 86-100 points[(93.7±4.14)points],which was significantly higher than the preoperative score of 65.7 (P <0.05);There was no fracture displacement in the period of followed-up,drop of internal fixator,fracture and other complications.Conclusion HCS fixation under arthroscope in treatment of patella fracture is effective.The joint function recovered quickly with less complica-tion.It could be one of the effective methods for the treatment of patella transverse fracture.
