Objective To investigate the clinical effect of the treatment of osteoporotic vertebral compression fractures in the elderly populationthrough different surgical approaches.Methods 98 cases with a single-level osteoporotic vertebral compression fracture in the elderly population were randomly divided into two groups from February 201 1 to June 2013.48 patients were performed by percutaneous vertebroplasty (PVP)through unipedicular approach and 50 patients through bipedicular approachs.The clinical data of patients were prospectively analyzed and the clinical efficacy were compared between two groups using VAS (visual analogue scale method)and ODI (Oswestry disability index)in preoperative,postoperative 1 day and 1 year postoperatively .The data of age, gender,injury to the patients with operation time,postoperative follow-up time,operation time,bone cement injection,bone cement leakage and other complications were observed.Cobb angle,vertebral compression ration were observed by imaging data.Results All the cases were followed-up.There was no statistical difference in preoperative clinical data between the two groups (P >0.05).In unilateral group (48 cases),the data of operation time,bone cement injection,bone cement leakage,Cobb angle improve,vertebral compression ration improve were (34.87±5.91)min,(6.20±0.66)mL,1 6 cases(33%),(10.1 9±2.12)%,(13.23°±1.58°)and adjacent vertebral fractures was 10 cases (20.9%).VAS score was respectively improved (4.05 ± 0.12 ),(5.42 ± 0.12 ) in postoperative 1 day and 1 year than preoperative.VAS score was improved (1.40 ±0.1 1 )in postoperative 1 year than 1 day.ODI score was respectively improved (35.46 ± 1.89)%,(47.88 ±2.21 )% in postoperative 1 day and 1 year than preoperative.ODI score was improved (1 1.42±0.24)% in postoperative 1 year than 1 day.In bilateral group (50 cases).The data of operation time,bone cement injection,bone cement leakage,Cobb angle improve, vertebral compression ration improve were (41.66±6.90)min,(4.88±0.52)mL,9 cases(18.0%),(10.48±1.43)%,(13.04°±2.03°)and adjacent vertebral fractures was 6 cases(12.0%).VAS score was respectively improved (4.06±0.1 1),(5.30±0.10)in postoperative 1 day and 1 year than preoperative.VAS score was improved (1.34± 0.08)in postoperative 1 year than 1 day.ODI score was respectively improved (36.08±2.13)%,(47.54±1.97)%in postoperative 1 day and 1 year than preoperative.ODI score was improved (1 1.26 ± 0.54)% in postoperative 1 year than 1 day.There was no obvious clinical problems after occurred leakage in two groups.there was statistical difference in cement injection,bone cement leakage and postoperative adjacent vertebral fractures after operation between the two groups.there was no statistical difference in Cobb angle improve,vertebral compression ration improve,VAS score and ODI score between the two groups.Conclusion Both approaches are effective in the treatment of osteoporotic vertebral compression fractures in the elderly population ,but there is advantage of decrease the incidence of bone cement leakage and postoperative adjacent vertebral fractures through bilateral approach.

Objective To compare the clinical efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and Quadrant minimally invasive system in treatment of lumbar disc herniation (LDH). Methods 59 single-level LDH patients were randomly divided into PTED group (n = 31) and Quadrant group (n = 28). Then compare the operative time, incision length, blood loss, length of hospital stay, and the return-to-work time between the two groups. In addition, visual analogue scale (VAS), Japanese Orthopedic Association (JOA), Oswestry disability index (ODI), and modified MacNab criteria were used for surgical efficacy evaluation. Results In PTED group, compared with Quadrant group, we observed, shorter incision length, less blood loss, shorter hospital stay, and shorter time of returning to work (P < 0.05), postoperative VAS, JOA and ODI scores had been improved in both groups (P < 0.05). The PTED group had lower VAS scores of lumbago at 3 days and 1, 3 months postoperatively (P < 0.05). As for postoperative JOA and ODI score, no notable difference was found between the two groups at each corresponding follow-up time point (P > 0.05). According to the improved MacNab criteria, there was no significant difference in excellent or good rate between the two groups (P > 0.05). Conclusion The clinical results of PTED and Quadrant minimally invasive system in treatment of lumbar disc herniation were satisfactory, and PTED were less traumatic method with rapid recovery.

Objective To investigate the effect of functional training on knee pain,functional movement screen (FMS) score and balance in Chinese elite fencing athletes with patellar tendinopathy.Methods Twenty-four fencing athletes with a diagnosed patellar tendinopathy were randomized into a treatment group (TG) and a control group (CG),each of 12.Both groups were given routine physical therapy,while TG received motor function training in addition for eight weeks.Both groups completed the numerical rating scale (NRS),FMS and balance test before and after the intervention.Results After the intervention,the average PRS and FMS of TG were 2.08± 1.24 and 16.25±0.97 respectively,which significantly outperformed those of TG before the intervention and those of CG after the intervention (P＜0.05).Moreover,TG indicated superior results in parameters of static postural balance including center of pressure,total length of swinging pathway,maximal length of swinging pathway,and area of swinging pathway when compared to TG before the intervention and CG after the intervention(P＜0.05).Conclusion The motor functiontraining is effective in improving functional movement and balance in elite fencing athletes with patellar tendinopathy.

Objective To investigate the characteristics of mental rotation in stroke patients and the relationship between mental rotation and visual-spatial cognitive function. Methods From March, 2012 to October, 2013, 30 stroke patients were selected as experimental group and 30 healthy subjects as control group. They were tested with hand mental rotation task, and assessed with visuospatial abilities from Mon-treal Cognitive Assessment (MoCA). Results The reaction time of hand mental rotation task was significantly longer in the experimental group than in the control group (F=95.6, P<0.001). The reaction time was longer with the increase of rotation angle in both groups, and was the longest as 180° of rotation (F=345.672, P<0.001). The response accuracy rate of hand mental rotation task was significantly lower in the experimental group than in the control group (F=6.444, P<0.05). The response accuracy rate was lower with the increase of rotation angle in both groups, and was the least as 180° of rotation (F=102.911, P<0.001). The reaction time negatively correlated with the score of visuospa-tial abilities, while the response accuracy rate positively correlated with it in the stroke patients (P<0.05). Conclusion The mental rotation ability is impaired in stroke patients, however, the respondent pattern is similar to healthy people. The mental rotation ability is correlated with visual-spatial cognitive functions in stroke patients.

‍Liver failure is a serious clinical syndrome of liver disease with critical condition and high mortality， and besides liver transplantation， there is still a lack of satisfactory radical treatment methods. The pathogenesis of liver failure is complex and remains unclear， involving a variety of factors that affect the balance of hepatocyte necrosis and regeneration. This article summarizes autophagy as the key pathway for maintaining cell homeostasis and points out that autophagy plays an important protective role in the pathogenesis of liver failure by regulating NLRP3 inflammasome activation， reducing oxidative stress， and inhibiting cell apoptosis. Meanwhile， it is believed that the molecular signaling pathways targeting autophagy， such as exosomes and peroxisome proliferator－activated receptor α， participate in antagonizing the development and progression of liver failure and will become important ideas and directions for molecular targeted therapies for liver failure.

Objective:To analyze the clinical efficacy and safety of endoluminal treatment of complex renal artery aneurysm (RAA).Methods:The clinical data and follow-up results of 19 patients with complex RAA admitted to Renji Hospital, Shanghai Jiaotong University School of Medicine from November 2014 to September 2021 were retrospectively analyzed. Two patients were treated with simple spring coil embolization into the aneurysmal artery, 14 patients were treated with simple spring coil embolization of the aneurysmal cavity, and 3 patients were treated with stent-assisted + spring coil embolization technique. Based on the location of the aneurysm, RAA were classified into type Ⅰ, Ⅱ, and Ⅲ. 7 patients with type Ⅰ, 10 patients with type Ⅱ, and 2 patients with type Ⅲ were studied. Variance analysis was used to compare the differences in glomerular filtration rate(GFR) of the affected side when the tumor was located at different locations, and Pearson was used to analyze the correlation between the number of coils implanted and the size of the tumor and GFR.Results:Ten of the 19 patients who were underwent successful endoluminal intervention. The average size of the patients′ aneurysms was (20.89±6.65) mm, and the average number of spring coils implanted was 8.22±3.08. The preoperative and postoperative serum creatinine were in the normal range, and no RAA tumor enlargement or recurrence was found during the follow-up period. The postoperative GFR was abnormal in patients with type Ⅰ, type Ⅱ, and type Ⅲ renal aneurysms, and the mean GFR value differed among the three types of patients( P=0.003). There was a negative correlation between the postoperative GFR values of the affected kidney and the number of spring coils implanted ( P=0.047), and no significant relationship between GFR and aneurysm size. Conclusion:The endovascular technique is an effective and safe means of treating complex RAA.
