It can significantly improve the TCM syndrome and single symptom of patients with good safety .

Atherosclerosis is the major cause of ischemic stroke.Given the importance of the early diagnosis and intervention of atherosclerotic plaques,the use of molecular imaging techniques for early diagnosis of atherosclerosis has become a research focus in recent years.This article reviews the advances in research on molecular imaging in the aspect of early diagnosis of atherosclerosis.

To compare the clinical efficacy of treating Denis type B thoracolumbar burst fracture with allogenic bone and calcium sulfate implanting in injured vertebra.A total of 46 patients were randomly assigned into 2 groups.Group A( n=22) received allogenic bone implanting in injured vertebra while group B( n=21) had calcium sulfate grafting in injured vertebra.Group A was better than group B in maintaining tanterior vertebral body height and lessening the degree of bone defect ( P <0.05 ).No significant differences existed in operaive duration , blood loss volume, correcting Cobb′s angle, preventing degeneration of adjacent segments , visual analogue scale ( VAS) and Japanese Orthopaedic Association ( JOA) scores and the degree of bone defect ( P>0.05).

BACKGROUND: Lateral locking plate is a classical fixation method to treat lower and distal femoral fractures. However,the incidences of delayed healing, nonunion, plate extubation, and internal fixation rupture exceed 20% after internal fixation.OBJECTIVE: To compare the effectiveness of augmentation plating and single plating for distal and lower femoral fractures with medial comminution.METHODS: Totally 60 patients of lower and distal femoral fractures with medial comminution treated with open reduction and plate fixation were divided into augmentation plating (treatment group, 28 cases) and single lateral plating (control group, 32 cases). We observed the operation time and blood loss, recorded the out-off-bed rehabilitation time, full weight bearing time and complication. The functionary recovery of knee joint was evaluated according to Schatzker-Lambert method for distal femoral fractures in final follow-up.RESULTS AND CONCLUSION: (1) All patients were followed for at least 12 months. All incisions were healed by first intention. (2) The operation time and blood loss in the treatment group were greater than those in the control group (P <0.05). (3) The healing time (3.11±0.31 months), out-off-bed rehabilitation time (4.36±0.91 weeks), full weight bearing time (3.67±0.62 months), complication (0) and excellent and good rate of knee functionary recovery (100%) in the treatment group were better than those in the control group [(5.65±2.33), (7.25±1.02), (6.03±2.61) months, 8, 65.6%] (P < 0.05). (4)Although augmentation plating for treatment of lower and distal femoral fractures with medial comminution prolongs operation time and increases surgical blood loss, the results including the healing rate, complication and satisfaction rate are superior to those treated with single lateral plating.

Objective To investigate the influencing factors and technical points of induced membrane technique for treatment of bone defect.Methods All of 20 patients of bone defect were treated by induced membrane technique in our hospital from January 2008 to November 2014,including 15 males and 5 females;aged 13-69,average 38.5;infectious bone defect in 16 cases and non-infectious bone defect in 4 cases.Record the complications,evaluate the healing of bone defect and functional recovery of adjacent joints by Paley method,respectively,and grade the range of movement (ROM) of adjacent joints by authors's method.Results In the first stage of surgery,1 case needed a second operation as the wound gradually spitted and bone cement contaminated after tighten closure of the skin flap,while others had no infection or recurrence of infection.In the second stage of surgery,3 cases had induced membrane damage and defect.All were followed-up from 12 to 50 months (average 19.7 months);all the bone defects healed,the clinical healing time was 3.0 to 7.0 months (average 4.7 months).The healing time in the 3 cases with induced membrane damage and defect (average 6.0 months) was longer than that in patients without induced membrane damage and defect(average 4.6 months).1 case of infectious bone defect with induced membrane damage and defect had local infection in 6 months after the second stage of surgery,for whom the conservative treatment was invalid but got controlled after second operation while 1 case of infectious bone defect without induced membrane damage and defect had local infection in 12 months after second stage of surgery,in whom the infection was controlled by the conservative treatment,the others had no infection or recurrence of infection,no broken of fixators noted;at the last follow-up,all the bone defect healing graded excellent,the functional recovery of the adjacent joints graded:excellent in 8 cases,good in 10 cases,and fair in 2 cases (the excellent and good rate was 90％),the ROM of the adjacent joints graded:excellent and good in 8 cases,respectively,fair and poor in 2 cases,respectively (the excellent and good rate was 80％).Conclusion Induced membrane technique has advantages of simple surgery,faster healing of bone defect,no correlation between the healing time and the length of bone defect,fewer complications,etc,but in clinical application,the operators must understand the therapy principle and pay attention to the influencing factors and technical points so as to avoid operation errors,reduce complications and improve therapeutic effect.

Objective To discuss the surgical techniques and results of internal fixation supplemented with soft tissue repair of triad injury of the elbow via the combined anterior-lateral approach.Methods A retrospective analysis was done on 15 patients with triad injury of the elbow treated from January 2011 to August 2014.There were 10 males and 5 females,aged 38.4 years (range,20-61 years).Injury resulted from traffic accidents in nine patients,high-level falls in three and groundlevel falls in three.Radial head fractures were Mason type Ⅰ in five patients,type Ⅱ in eight,and type Ⅲ in two.Fractures of the coronoid process of the ulna were Regan-Morrey type Ⅰ in four patients,type Ⅱ in ten and type Ⅲ in one.Time interval between injury and operation was 8.5 d.All patients were firstly operated on through the anterior approach to have Herbert screw fixation or anterior capsule suture lasso fixation of the coronoid fracture as well as Herbert screw fixation of the radial head fracture.And then,elbow lateral incision was made to repair lateral collateral ligament complex and common extensor tendon by 2-0 Ethibon suture.Elbow flexion-extension,forearm pronation-supination and Mayo elbow performance score (MEPS) were used to evaluate the clinical elbow functions.Complications were recorded after operation.Results All patients were followed up for mean 19.6 months (range,12-30 months).All coronoid fractures healed.Radial head fractures in 14 patients healed.Comparison of preoperative to final follow-up variables presented significant differences in elbow flexion-extension [(45.1 ± 5.6) °:(129.5 ± 9.3) °],forearm pronation-supination [(55.4 ±.8.7) °:(140.5 ± 10.3) °] and MEPS [(25.1 ± 9.6) points:(91.2 ± 5.2) points] (P ＜ 0.01).Complications included heterotopic ossification in one patient and nonunion of radial head fracture in one patient.No neurovascular injury of the elbow,elbow residual instability,dislocation,elbow stiffness and active pain occurred.Conclusion Combined anterior-lateral approach with internal fixation and soft tissue repair is a simple and safe method that effectively restore the elbow joint function.

Objective To investigate the effects of Zuogui Jiangtang Yishen decoction (ZGJTYS) on the expression of nephrin and podocin in podocyte of MKR mice with diabetic nephropathy (DN), and explore its mechanism. Methods Forty MKR mice (8 weeks old) were randomly divided into four groups as follows:negative control group (group A), DN model group (group B), ZGJTYS group (group C) and positive control group (group D, Gliquidone and benazepri). All mice from group B, C and D were received high-fat diet feed and unilateral nephrectomy. Four weeks after operation, all mice were received drug intervention, and four weeks later, all mice were put to death. The levels of UmAlb were observed by ELISA, the serum BUN and Cr by biochemical, and the FBG by electrochemical detection method. The nephrin and podocin mRNA expression were measured by RT-PCR and the protein expression by western blotting. The morphological structure changes of the podocytes were observed by transmission electron microscopes. Results As compared with group A, FBG, BUN, SCr and urine UmAlb in the mice of group B increased significantly (P<0.01), the expression level of nephrin and podocin mRNA and protein were markedly decreased (P<0.01). After intervention of drugs, all biochemical indicators above in the mice of group C and D significantly decreased (P<0.01), the expression level of nephrin and podocin mRNA and protein were markedly increased (P<0.01, P<0.05), compared with group B. The renal pathological lesions of group C and D were significantly improved compared with group B. Conclusion ZGJTYS decoction exerts reno-protective effect via reinstating nephrin and podocin expression to repair the damaged podocyte.

Objective To investigate the augmentation plating for femoral fractures and postoperative femoral nonunion. Methods A retrospective analysis was conducted of 60 patients with femoral fracture or postoperative femoral nonunion who had been treated with augmentation plating from January 2008 to July 2015. They were 36 males and 24 females, aged from 15 to 79 years ( average, 43. 4 years ) . Of them, 20 cases suffered nonunion following intramedullary nailing of femoral shaft fracture, 18 nonunion following lateral plating for femoral distal or lower fracture, and 22 femoral distal or lower fracture complicated with comminuted fracture of medial column. An incision ranging from 6 to 10 cm was made around the fracture ends for augmentative plating for all the patients. Autogenous iliac bone graft was performed in patients with atrophic nonunion or ob-vious gap after reduction of the comminuted fracture. Operation time, intraoperative bleeding, healing time, complications, and functionary recovery of the affected knee were recorded. Results The operation time averaged 121. 5 min and the intraoperative bleeding 356. 3 mL. All the patients were followed up for 12 to 36 months ( average, 16. 9 months ) . All the fractures and nonunions healed after an average time of 4. 2 months ( from 3 to 4 months ) . The time for initial partial weight-bearing averaged 4. 5 weeks ( from 2 to 6 weeks ) and the time for initial full weight bearing 3. 3 months ( from 2 to 4 months ) . Evaluation according to the Karlstrom and Olerud criteria at the last follow-up revealed 29 excellent, 24 good and 7 fair cases, yielding an excellent and good rate of 88. 3％. No infection, loosening, bending or breaking of internal implants, or refracture was noted during follow-ups. Conclusion Augmentation plating through a small incision can lead to fine outcomes for femoral fractures and postoperative femoral nonunion, because it makes up the deficient stability of original in-ternal fixation, reduces the dislocated bone blocks and provides bone grafting to improve defective local bone structure and defective osteogenesis.

Objective To explore the therapeutic efficacy of arthroscopy-assisted minimally invasive treatment for posterior tibial plateau fractures.Methods From July 2010 to June 2014,10 posterior tibial plateau fractures were treated at our department by arthroscopy-assisted minimally invasive treatment with percutaneous lag screws.They were 8 men and 2 women,with a median age of 31 years (from 18 to 52 years).All the fractures were closed and fresh,including 3 posteromedial tibial plateau ones,5 posterolateral tibial plateau ones,and 2 posteromedial and posterolateral tibial plateau ones.They were followed up periodically by radiological examinations.At the final follow-up,their knee functions were evaluated by Rasmussen scoring system,and their pain was evaluated by the visual analogue scale(VAS).Subjective factors included swelling,stairs climbing,joint stability,job participation and satisfaction with recovery.Results The follow-ups averaged 18 months (from 12 to 24 months).All fractures healed within 3 months postoperatively,with no infection or serious complications like implant failure.At 12 months postoperation,the mean Rasmussen score was 26 points (from 19 to 30 points).Eight cases were rated as excellent,one as good,and one as fair.Their mean VAS score was 1.2 points (from 0 to 4 points).Conclusion Arthroscopy-assisted minimally invasive management of posterior tibial plateau fractures with cannulated screw fixation is feasible,because it results in limited invasion,satisfactory reduction,reliable fixation,quick functional recovery and a low rate of complications.

Objective To evaluate the improvement of lower urinary tract symptoms in benign prostatic hyperplasia (BPH) patients with bladder calculi by lithotripsy and adjuvant traditional Chinese decoction. Methods A total of 72 BPH patients with bladder calculi were recruited and randomly divided into the non-adjuvant treatment group (37 patients) and the adjuvant treatment group (35 patients). The adjuvant treatment group received adjuvant traditional Chinese decoction from 2 days before lithotripsy for 2 weeks. The maximum urinary flow rate (Qmax) , residual urine volume (RU), International Prostate Symptom Score (IPSS) and Quality of Life (QOL) were assessed before and after the treatment. The time of urine routine returned to normal and the indwelling time of catheter were compared between two groups. Urinary incontinence and recurrent bladder calculi were followed up for 6 months. Results After the treatment, the score of the IPSS (12.9 ± 4.5 vs. 15.7 ± 3.9;t=2.826, P=0.006) and the RU (47.3 ± 9.2 ml vs. 58.4 ± 11.3 ml;t=4.556, P<0.001) in the adjuvant treatment group were significantly lower than those in the non-adjuvant treatment group, and the Qmax (30.4 ± 4.7 ml/s vs. 21.4 ± 3.9 ml/s;t=8.862, P<0.001 ) was significantly higher. The indwelling time of catheter (5.7 ± 2.1 d vs. 8.1 ± 2.2d;t=4.730, P<0.001) and the time of urine routine returned to normal (6.9 ± 2.3 d vs. 10.2 ± 3.1 d;t=5.106, P<0.001) in the adjuvant treatment group were significantly shorter than those in the non-adjuvant treatment group. The 6-month follow-up showed that the incidence of urinary incontinence (2.9% vs. 18.9%;χ2=4.698, P=0.030) and recurrent bladder calculi (5.7% vs. 24.3%;χ2=4.813, P=0.028) in the adjuvant treatment group were significantly shorter than those in the non-adjuvant treatment group, and the total effective rate was significantly higher (62.9%vs. 29.7%; χ2=6.672, P=0.011). Conclusions Lithotripsy and adjuvant traditional Chinese decoction can reduce the IPSS score and RU, increase Qmax, decrease urinary incontinence and recurrent bladder calculi, and improve lower urinary tract symptoms in BPH patients with bladder calculi.
