Objective: To investigate the guiding significance of pterional approach head positional three-dimensional digital subtraction angiography (3D-DSA) in intracranial aneurysm clipping. Methods: One hundred fifty patients with aneurysmal subarachnoid hemorrhage were enrolled in the study. Three-dimenlional angiography was performed after detecting the aneurysms with conventional angiography, and then, the images of 3D-DSA were rotated to the head position for the pterional approach. The size of aneurysm, spatial location, aneurysm neck, and the relationship between aneurysm and patent artery revealed by the images were compared to the conditions at surgical exposure through pterional approach. Results: Of the 150 patients, the diameter of aneurysm revealed by 3D-DSA in 140 patients were in accordance with the intraoperative measurements, the coincidence rate was 93.3%; the coincidence rate of the spatial location between the aneurysms and its parent arteries was 100%. A total of 149 aneurysm clips were selected before the surgery according to 3D-DSA. Six clips were replaced during the operation because it was inconsistence with the prediction before the surgery, and the accurate rate was 96.0% (143/149). The related perforating arteries or adjacent vascular branches of aneurysms in 49 patients were identified before the surgery according to 3D-DSA. The major adjacent blood vessels missed by 3D-DSA in 11 patients were detected during the surgery, and the coincidence rate reached 81.7%. These vessels were all completely preserved during intraoperative anatomical separation under the direct vision. Conclusion: Head positional 3-D DSA for simulate pterional approach may accurately provide information of local blood vessels of aneurysm before surgery, and it plays a good guiding role for surgical clipping of aneurysms.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Objective To evaluate the application of real-time three-dimensional transesophageal echocardiography (RT-3D TEE)in left atrial appendage (LAA)closure.Methods After excluding valvular disease,21 of 36 atrial fibrillation (AF)patients suffered the percutaneous LAA closure were chosen to measure left ventricular ejection fraction (LVEF)and to observe if the thrombus or the cloudiness echo will occur.The multiple planner reconstruction function was applied to rebuild sections and to observe the LAA anatomical morphology and its internal structure.During operation,the Flexi Slice function was used to measure the dimensions of LAA ostium,RT-3D mode was used to monitor sheath transport and closure device release,and to immediately evaluate the effect of blocking and complications after the operation. Results The exam before the closure procedure showed 5 of 36 patients' left ventricular ejection fraction (LVEF)<40% and one or more thrombus or the cloudiness echo were found in other 10 patients' which were thus excluded from the study.RT-3D TEE examination in the 21 patients revealed 8 single-lobe cases, 8 double-lobes cases and 5 patients with multi-lobe.Two patients of them need a special device.The maximum dimensions of LAA ostium was (22.24±4.35)mm,the fixed plate size of conventional LAmbreTM device was (28.26±5.23)mm.All patients choiced an average (1 .1 ±0.30)closure device and get the best sealing effect evaluated by RT-3D TEE immediately after operation,10 cases of them has about 1 -3 mm residual leakage exist around the closure.None of the patients with a new pericardial effusion and cardiac tapenade,no closure shift and embolism events.Conclusions RT-3D TEE can real-time and dynamically observe LAA anatomical morphology and its internal structure,compared with other imaging techniques, RT-3D TEE has irreplaceable advantages in the percutaneous LAA closure.

BACKGROUND:There are many ways for surgical treatment of distal radius fractures. Both volar locking plates and Kirschner wires are common methods. Doctors have considerable flexibility in the choice of the ways of fixation, but both at home and abroad there is no comparison between the effects of the two operations for treating distal radius fractures. OBJECTIVE:To systematicaly review the differences in effectiveness and safety of volar locking plates versusKirschner wires for distal radial fracture. METHODS:Databases such as CBM, CNKI, VIP, PubMed and Cochrane Library were electronicaly searched.Chinese Journal of Orthopaedics,Chinese Journal of Orthopaedic Trauma,Chinese Journal of Trauma andJournal of Practical Orthopaedics were searched by hand. In strict accordance with inclusion and exclusion criteria, articles were screened. Methodological quality of included studies was evaluated according to Cochrane Handbook. Data were extracted, and then analyzed with RevMan 5.2 software. RESULTS AND CONCLUSION:Nine randomized controled trials were included. Meta-analysis results demonstrated that upper limb function scores were better in the volar locking plate group than in the Kirschner wire group [MD=-4.55(-7.89,-1.21),P=0.008] at 3 months of folow-up and [MD=-3.13(-6.08,-0.18),P=0.004] at 12 months. The incidence of infection was lower in the volar locking plate group than in the Kirschner wire group [OR= 0.42(0.23, 0.79),P=0.007]. No significant difference in incidence of complex regional pain syndrome [OR=0.28(0.05, 1.38),P=0.12], incidence of carpal tunnel syndrome [OR=0.75(0.20, 2.76),P=0.66] and tendon injury [OR= 1.66(0.51, 5.41),P=0.64] was detected between the volar locking plate group and Kirschner wire group. These results indicated that compared with the Kirschner wire, volar locking plate fixation for the repair of distal radial fracture is safe and effective. In the permission of economic circumstances, it is suggested that elder osteoporosis patients with distal radial fracture should receive plate fixation.

Objective To study the efficacy of medication management, symptom management and community reentry skills-training modules to prevent rural patients with schizophrenia from relapse and increase their social function.Methods 89 subjects were randomly assigned to the skills training group (45 cases) and the control group (44 cases). Both groups received the same treatments, but the skills training courses were given to the skills training group for twelve weeks when the subjects were addmitted into the trial and at their one-year follow-up timepoint respectively. And a two-year follow-up was carried out. All subjects were evaluated with PANSS, SDSS, relapse and employeement.Results 89 subjects had completed the study. The skills training group demonstrated clinical Results significantly superior to those of the control group on overall improvement according to PANSS and SDSS. Substantially, statistically significant advantages of the skills training group were related to 1) the rate of relapse (11.1% vs 31.8%), 2) the rate of employment (37.8% vs 15.9%).Conclusion Medication management, symptom management and community-re-entry skills-training modules are effective in reducing patients' psychiatric symptoms, preventing them from relapse and increasing their social function.

Objective　To report a 4-year cumulative series (209 cases) of laparoendoscopic singlesite surgery (LESS) in urology and assess its clinical utilization.　Methods　Consecutive LESS cases done between December 2008 and July 2012 at our institution were prospectively recorded and retrospective analyzed in this study.Demographic data,main perioperative outcomes,and information related to the surgical technique were collected and analyzed.There were 209 patients ( 121 males and 88 females) with a mean age of (52.8 ±14.5) years,a mean B MIof (23.5 ±3.12) kg/m2 and a mean ASA score of (2.0±0.3).20.1％ (42 cases) of patients had previous abdominal or pelvic surgeries.29.2％ (61 cases) and 12.9％(27 cases) of patients had diabetes mellitus and hypertension. Indications were renal tumors (70 cases,33.5％),adrenal tumors (42,20.1％),renal cyst (22 cases,10.5％),ureteral calculi (22 cases,10.5％),nonfunctional kidneys (19 cases,9.1％),BPH (10 cases,4.8％),and others (24 cases,11.5％ ).Surgical conversions were evaluated,as well as intraoperative and postoperative complications.Two periods were arbitrarily dcfined:the first was from December 2008 to Septcmber 2010 (22 mon) and the second.was from October 2010 to July 2012 (22 mon).A comparative analysis between these two periods was conducted.　Results　There were 209 LESS surgeries included in this study.Most common procedures ( 92.3％ ) were done on the upper urinary tract,with 55.5％ of the whole cohort being tumor-related indications and only 16.3％ being reconstructive procedures.The transperitoneal approaches were preferentially adopted in 80.9％　cases,and transvesical access in 5.3％ cases. The transumbilical access was used in 46.9％ of cases.The overall conversion rate was 8.1％,with 4.3％ of cases converted to reduced - port laparoscopy,1.9％ to conventional laparoscopy,and 1.9％ to open surgery.The intraoperative complication rate was 4.8％ ( 10/209 ) and postoperative complications,mostly low grade,were encountered in 11.5％(24/209) of cases.There was a significant increase in the number of LESS cases during the second study period; the rate of some procedures (ie,transumbilical LESS,renal cyst decortication and transvesical single-port enucleation of the prostate) was lower,whereas some other procedures were performed more frequently (ie,tumor-related LESS procedures,radical nephrectomy and adrenalectomy).　Conclusions　A broad range of urological procedures can be finished with LESS technique in the experienced hands of a laparoscopic surgeons.However,LESS is still in its infancy with a certain risk of surgical complication and conversion.Stringent patient selection criteria should be applied,especially during the learning curve.Complex reconstructive procedures or malignant tumor related indications are not appropriate as the start of this kind of procedure.We need always put patient's safety and treatment efficacy first.

Objective To report a 33-year-old man with post-headache stroke-like episodes,with whom ischemic changes were found in basal ganglia and occipital-temporal lobe and muscle biopsy revealed abnormal mitochondrial structure and function without regular mutations detected in mtDNA.Methods Gene chip technique was used to detect the mutation of whole sequence of mtDNA,and direct sequencing technique was used to confirm the mutations.Results Three mutations were found.A new mutation in the mitochondrial cytochrome C oxidase subunit 1 (MTCO1),a T→C transition at nucleotide position 6253 resulted in conservative methionine transferring to threonine.His mother also held the mutation,which was not found in 98 control samples.So T6253C was considered the nosogenetic mutation.Conclusion This is the first time to report a mutation in MTCO1 responsible of MELAS.
