Objective To evaluate combination of cholcdochoscopy or duodenoscopy with therapeutic laparoscopy (LCDCS) in treatment of detail choledochus stones. Methods Laparoscopic cholecystectomy was firstly performed and followed by choledochoscopy or duodenoscopy. Procedures of therapeutic choledochoscopy were as follows: choledochoscopic exploration via cystic duct remnant, choledochotomy, electrohydralic lithothipsy, drainage of bile duct with ureteral catheter via cystic duct remnant, T-tube drainage, or the suture of duct incision. Procedures of therapeutic duodenoscopy were as follows: access to the common bile duct and duodenum through ureteric catheter and zebra guidewire via cholecystic duct remnant, duodenoscopy via oral cavity into the duodenum papilla, papillotomy with needle-knife or arch-like electro-knife along the ureteric catheter or zebra guidewire, and stone clearance in the common bile duct with the reticulation and balloon of duodenescopy. Results Combination therapy were given to 191 cholelithiasis patients with detail choledochus stones. Combined choledochoscopy were performed in 117 patients. Stones were completely removed and average operation time was 114 min. Bile leakage occurred in 7 cases, but was cured with drainage. Postoperative imaging showed 2 cases of bile duct stenosis at primary closure of duct incision. Combined duodenescopic procedures were performed in 74 patients. Papillotomy and stone clearance were successfully performed in 68 patients, 5 others of whom underwent successful papillotomy only, and another underwent other operations. Average operation time was 97 min. Post-operation mild acut pancreatitis developed in 6 patients. No perforation of intestine or bile duct, bleeding, severe pancreatitis, or death was observed in each group. Conclusion LCDCS was safe and effective with appropriate indications.

Objective To explore the operative methods and indications of duodenoscopic papillotomy during the course of operation(IEPT)for cholelithiasis.Methods Cholecystectomy was firstly conducted under the condition of laparoscopy or open laparotomy.For the gross choledochus,the common bile duct was cut open to clear the stones.The ureteric catheter and zebra guidewire were inserted into the common bile duct and duodenum.Then they were inserted via duodenoscopy into thepapillum of duodenum.The papillary stenosis was removed with electro-knife by pin-head-like and arch-like to track along the ureteric catheter and zebra guidewire.For the tiny choledochus,the ureterie catheter and zebra guidewire were inserted via the cholecystic duct remnant into the common bile duct and duodenum.Then they were inserted via duodenoscopy to perform papillotomy to clear the stones of the common bile duct with the reticulation and the balloon of duodenoscopy.Results Forthe gross choledochus,IEPT in laparoscopy was successful in 45 cases and the other 2 received other operation.IEPT in open laparotomy was successful in 5 cases.For the tiny choledochus,IEPT in laparoscopy was successful in 73 cases and the other 1 underwent other operation.IEPT in open laparotomy was successfulin 2 cases.Conclusion If patients are suitable,IEPT is safe and effective in the hands of skilled endoscopiests for laparoscopy and open laparotomy.

Objective To study the applied value of multi-slice spiral CT(MSCT)in pulmonary lesions.Methods 68 cases with massive hemoptysis caused by lung tumor or other reasons underwent 16-slice spiral CT scan including plain and contrast-enhanced scan.Volume reconstruction(VR),multiplanar reconstruction(MPR),maximum intensity projection(MIP)and curved planar reconstruction(CPR)were performed using original images.The origin,number and shape of vessels feeding lesions were observed.Results Among 68 cases(two failed),the blood supply of pulmonary lesions was from bronchial artery in 60 cases,from the intercostals artery in 8 cases,from the internal thoracic artery in 5 cases,from the left subclavian artery in 6 cases,from the right inferoir phrenic artery in 5 cases,from the celiac trunk artery in 3 case and from the right renal artery in 1 case.The blood supply was from single artery in 50 cases,double arteriae in 10 cases and three arteriae in 6 cases.The supply arteriae were vascular plexus in 55 cases,meandering in 8 cases,net in 2 cases and aneurysm formation in one cases.Conclusion MSCT can clearly display the vessels feeding pulmonary lesions.

Objective To observe the effect of digital acupressure plus mechanical sputum expectoration on the rehabilitation of patients with stroke-associated pneumonia. Method Forty-six patients with stroke-associated pneumonia were randomized into a treatment group of 22 cases and a control group of 24 cases. The treatment group was intervened by digital acupressure plus mechanical sputum expectoration, while the control group was by mechanical sputum expectoration alone. The simplified version of Clinical Pulmonary Infection Score (CPIS), Fugl-Meyer assessment scale, and modified Barthel Index (BI) were adopted for evaluation before and after intervention. Result After treatment, CPIS, Fugl-Meyer and BI scores were changed significantly in both groups (P<0.01). There were significant differences in comparing the CPIS, Fugl-Meyer and BI scores between the two groups after intervention (P<0.05). After intervention, the two groups showed a negative correlation between CPIS score and Fugl-Meyer score, as well as between CPIS score and BI score. Conclusion Digital acupressure plus mechanical sputum expectoration can effectively improve the pulmonary symptoms in patients with stroke-associated pneumonia, benefiting the rehabilitation of the post-stroke patients.

Objective To compare intramedullary nail (IN) and dynamic hip screw (DHS) regarding their effects on hip abduction following fixation of intertrochanteric fractures.Methods From January 2008 to December 2015,310 patients with intertrochanteric firacture were treated at our department.They were divided into 2 groups depending on the manner of treatment.198 patients (71 males and 127 females) were subjected to intramedullary nailing,with an average age of 74.7 ± 5.6 years;there were 50 cases of 31-A 1,134 ones of 3 1-A2 and 14 ones of 3 1-A3 according to the AO classification.112 patients (35 males and 77 females) were subjected to dynamic hip screwing,with an average age of 74.1 ± 6.7 years;there were 24 cases of 31-A1,78 ones of 31-A2 and 10 ones of 31-A3.The 2 groups were compared in terms of time for weight-bearing ambulation and stand on one leg,gait,pelvic tilt,range of hip active abduction,muscle strength of the abductor and hip function at the final follow-up.Results Of this series,284 patients were followed up for 1.5 to 8.5 years (average,3.6 years) and 26 patients died.The IN group achieved significantly better outcomes in terms of time for weight-bearing ambulation (37.6 ±4.9 d),time for stand on one leg (60.1 ± 9.5 d),cases of normal gait and normal pelvic tilt (171 and 179),muscle strength of the abductor (62.3 ±4.4 N · m),and range of hip active abduction than the DHS group (53.0 ±8.4 d;71.0 ± 12.0 d;67 and 85;56.6 ± 3.3 N · m,respectively) (P ＜ 0.05).There was no significant difference between the 2 groups in the hip function at the final follow-up(91.4％ versus 84.5％ in the excellent and good rate)(P ＞ 0.05).Conclusion Compared with dynamic hip screwing,intramedullary nailing has a limited effect on hip abduction so that the patients may benefit from quicker functional recovery and faster improvement in quality of life.

Objective To explore the advantages and security of orthopaedic TiRobot used to assist internal fixation with sacroiliac lag screws.Methods From December 2015 to August 2017,11 patients with fracture of pelvic posterior ring or sacroiliac separation were treated by internal fixation with sacroiliac lag screws assisted by an orthopaedic TiRobot at Department of Orthopaedic Surgery,Affiliated Hospital to Chengdu University.They were 7 men and 4 women,aged from 23 to 61 years (average,42.5 years).According to AO classification,there were one case of type B1.2,one case of type B2.2,6 cases of type C1.2,2 cases of type C1.3 and one case of type C2.3.The number of sacroiliac lag screws inserted,time for planning insertion approaches,fluoroscopy frequency,fluoroscopy time,exposure time of C-arm X-ray,operation time,blood loss and reduction quality were documented.Results The 11 patients were followed up for 5 to 22 months (average,9.5 months).A total of 15 sacroiliac screws were inserted.In the operations,time for planning insertion approaches averaged 8.5 minutes (from 9 to 25 minutes),fluoroscopy frequency 8.5 times (from 4 to 15 times),fluoroscopy time 5.5 minutes (from 3.2 to 6.5 minutes),exposure time of C-arm X-ray machine 5.8 seconds (from 2.4 to 16.3 seconds),operation time 34.5 minutes (from 25 to 45 minutes),and blood loss 35 mL (from 10 to 80 mL).All the screw positions were satisfactory,with no penetration into the sacral canal,sacral foramen or bone cortex.No postoperative neurovascular injury happened.All the incisions primarily healed.All the fractures united well after 4 to 7 months (average,5.6 months),without any screw loosening.By the Matta scoring for fracture reduction,9 cases were excellent,one was good and one fair.By the Majeed functional scoring for pelvic fractures,8 cases were rated as excellent and 3 as good at the last follow-up.Conclusion Orthopaedic TiRobots can be used to assist internal fixation with sacroiliac lag screws in the treatment of pelvic posterior ring injuries,with advantages of limited invasion,time,hemorrhage,and high safety and accuracy as well.

Angiokinases, such as vascular endothelial-, fibroblast- and platelet-derived growth factor receptors (VEGFRs, FGFRs and PDGFRs) play crucial roles in tumor angiogenesis. Anti-angiogenesis therapy using multi-angiokinase inhibitor has achieved great success in recent years. In this study, we presented the design, synthesis, target identification, molecular mechanism, pharmacodynamics (PD) and pharmacokinetics (PK) research of a novel triple-angiokinase inhibitor WXFL-152. WXFL-152, identified from a series of 4-oxyquinoline derivatives based on a structure-activity relationship study, inhibited the proliferation of vascular endothelial cells (ECs) and pericytes by blocking the angiokinase signals VEGF/VEGFR2, FGF/FGFRs and PDGF/PDGFR simultaneously . Significant anticancer effects of WXFL-152 were confirmed in multiple preclinical tumor xenograft models, including a patient-derived tumor xenograft (PDX) model. Pharmacokinetic studies of WXFL-152 demonstrated high favourable bioavailability with single-dose and continuous multi-dose by oral administration in rats and beagles. In conclusion, WXFL-152, which is currently in phase Ib clinical trials, is a novel and effective triple-angiokinase inhibitor with clear PD and PK in tumor therapy.
