Objective To discuss the safety and feasibility of radiofrequency ablation (RFA)combined with transcatheter arterial chemoembolization(TACE)for patients with primary liver carcer(PLC).Methods 64 cases with PLC were selected and randomly divided into two groups,32 cases in each group.The observation group accepted TACE combined with RFA therapy,while the control group only received TACE treatment.Term efficacy (after 1 year)and 1,2,3 -year survival rate were compared in the two groups.The changes of liver function parameters including aspartate aminotransferase (AST),alanine aminotransferase (ALT) and γ-aminoacyl transferase (γ-GT)of the two groups were analyzed and compared.Results After 1 year of treatment,the remission rate was 71.9% (23 /32)in the observation group,which in the control group was 43.8% (14 /32),the difference was statis-tically significant (χ2 =5.189,P <0.05).The 1,2,3 -year cumulative survival rates were 65.6% (21 /32),65.6%(21 /32)and 62.5% (20 /32)in the observation group,which in the control group were 37.5% (12 /32),28.1%(9 /32)and 21.9% (7 /32),the differences were statistically significant (χ2 =5.067,9.035,10.83,all P <0.05). After 2 months of treatment,AST,ALT and γ-GT levels in the observation group were significantly higher than those in the control group(t =4.218,2.449,8.647,all P <0.05).Conclusion TACE combined with RFA therapy can significantly improve the clinical symptoms of patients with PLC,which can improve liver function in patients and help prolong the survival time.

Cerebral palsy (CP) is one of the most common causes of physical disability among children all over the world.It is often accompanied by hypophrenia,epilepsy,abnormal behaviors,visual auditory disorder,emotional disturbance,facial disfunction,developmental delay,malnutrition,poor lung function,hypoimmunity,and so on.Also hip abnormalities are important issues.The hip subdislocation,dislocation and pain largely influence the daily life of the patients.Early detection and therapy offer a great hand to ease the degree of disability and enhance rehabilitation effect.Surgical management and rehabilitation training have significant count on maintaining the hip function and improving daily life quality.The lesion severity,treatment timing,individual differences and cooperation degree of parents are main factors of prognosis.This contribution summarizes the symptoms,radiographic parameter changes and treatments of CP.

The etiology and pathogenesis of Crohn’s disease(CD)are not fully clear,and genetic susceptibility, immunologic disorder,intestinal barrier dysfunction and intestinal microecology are considered to be involved in the pathogenic mechanism of CD. In recent years,the relationship between intestinal microecology and CD has received much attention. Several studies confirmed that the intestinal microecology in CD patients was different from that in normal person. The change of intestinal microecology was correlated with the occurrence of CD,and modulation of intestinal flora was effective in the treatment of CD. This article reviewed the relationship between intestinal microecology and CD and the therapeutic prospect of intestinal microecology for the treatment of CD.

Objective To observe the effect of duration of carbon dioxide pneumoperitoneum on coagulation, fibrinolysis and endothelial activation in elderly patients undergoing laparoscopic cholecystectomy (LC). Methods The 45 elderly patients with cholelithiasis scheduled for LC, aged over 60 yeas, were placed in different groups respectively after surgery according to the duration of pneumoperitoneum. The duration of pneumoperitoneum was ≤60 minutes in group A (n=21),and more than 60 minutes in group B (n=24). Venous blood samples were taken on admission (baseline), at the end of surgery, the 1st, 2nd and 3rd day after surgery for determination of prothrombin time (PT), activated partial thromboplastin time (APTT), prothrombin fragment F1+2 (F1+2), antithrombin 3 (AT-Ⅲ activity), fibrinogen (Fib), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-1), D-dimer (D-D), von Willebrand factor (vWF activity). Results Concerning the coagulation activation, at the 3rd postoperative day, the level of F1+2 was significantly higher in group B than in group A [(1.60±0.26) μg/L vs. (1.32±0.24) μg/L, P＜0.05]; AT-III was significantly higher in group B than in group A [(84.82%±20.21%) vs. (97.49%±16.87%), P＜0.05]. At the 2nd and 3rd postoperative day, the levels of Fib were significantly higher in group B than in group A [(3.87±0.62) g/L vs. (3.42±0.72) g/L, (3.98±0.77) g/L vs. (3.42±0.63) g/L, respectively, P＜0.05]. Concerning fibrinolysis, But at the 2nd and 3rd postoperative day, the level of PAI-1 was significantly higher in group B than in group A [(33.93±10.42) μg/L vs. (26.69±9.49) μg/L, (32.90±11.25) μg/L vs. (26.31±7.06) μg/L respectively, P＜0.05]. Concerning endothelial activation, at the 2nd and 3rd postoperative day, vWF was significantly higher in group B than in group A [(174.53%±44.03%) vs. (134.37%±37.74%), (176.31%±47.6%) vs. (131.21%±36.34%), respectively, P＜0.05]. Conclusions Marked activations of coagulation-fibrinolysis and endothelial activation are observed postoperatively in elderly patients undergoing laparoscopic cholecystectomy. Along with prolonged duration of pneumoperitoneum, more pronounced alterations of increased coagulation, reduced fibrinolysis and endothelial activation are observed, which could constitute an imbalanced situation of coagulation-fibrinolysis and increases the risk of venous thrombosis.

Objective To compare the changes in blood coagulation, fibrinolysis and endothelial damage in patients undergoing laparoscopic cholecystectomy with different durations of carbon dioxide pneumoperitoneum. Methods Sixty-four ASA Ⅰ orⅡpatients, aged 23-60 yr, weighing 45-82 kg, scheduled for elective laparoscopic cholecystectomy, were randomly divided into 3 groups according to the duration of pneumoperitoneum: duration of pneumoperitoneum ≤30 min group (group Ⅰ, n=21), 30 min ＜ duration of pneumoperitoneum ＜ 60 min (group Ⅱ, n=23) and duration of pneumoperitoneum≥ 60 min (group Ⅲ , n=20).The intra-abdominal pressure was maintained at 12-14 mm Hg. Venous blood samples were taken before surgery (baseline, T0 ),at the end of surgery(T1), and at 1, 2 and 3 d after surgery (T2-4) for determination of prothrombin time, activated partial thromboplastin time, concentrations of prothrombin fragment 1+2(F1+2), fibrinogen (Fib), tissue plasminogen activator and plasminogen activator inhibitor type-1 (PAI-1), and activities of antithrombin Ⅲ(AT-Ⅲ)and von Willebrand factor(vWF).Results Compared with groupⅠ , the vWF activity and PAI-1 concentration at T2 , concentrations of Fib, F1+2, PAI-1 and activity of vWF at T3 and concentrations of Fib and F1+2 at T4 were significantly increased, while the AT-IE activity at T3 was significantly decreased in group Ⅲ(P＜0.05) .Conclusion When the duration of pneumoperitoneum is short, no obvious changes in the blood coagulation, fibrinolysis and endothelial damage are observed postoperatively in patients undergoing laparoscopic cholecystectomy, and along with the prolongation of the duration of pneumoperitoneum, increased blood coagulation, reduced fibrinolysisand aggravated endothelial damage are observed postoperatively.

Objective To compare open versus closed reduction in treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours.Methods We retrospectively reviewed 51 children who had been treated at our department for femoral neck fracture between May 2005 and May 2012 after their reduction had been delayed for more than 24 hours.They were 37 boys and 14 girls,1.7 to 15.5 years of age (average,9.1 years).According to Delbet's classification,27 cases belonged to type Ⅱ,18 to type Ⅲ,and 6 to type Ⅳ.Of them,18 underwent closed reduction and 33 open reduction.Their complications were recorded in detail.Their therapeutic results were evaluated according to Ratliff's criteria and compared between the 2 methods of reduction.Results The 51 children were followed up for an average of 36.7 months (range,from 17 to 61 months).Anatomic reduction was achieved in 6 cases in the closed reduction group (33.3％) and 29 cases in the open reduction group (87.9％),respectively.All fractures healed after an average of 10.9 weeks (range,from 9 to 13 weeks),with one exception of nonunion in the closed reduction group.The incidence of femoral head necrosis in the closed reduction group (27.8％,5/18) was significantly higher than that in the open reduction group (15.2％,5/33) (P ＜ 0.05).According to the Ratliff's evaluation at the final follow-ups,the good to excellent rate in the closed reduction group(66.7％,12/18) was significantly lower than that in the open reduction group (84.8％,28/33) (P ＜0.05).Coxa vara occurred in 3 children in the closed reduction group but in none in the open reduction group.Conclusion Open reduction with internal fixation may lead to better outcomes than closed reduction in the treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours,probably because open reduction can result in better reduction quality.

Objective To compare the analgesic effects of epidural Morphine versus lumbosacral plexus block in patients undergoing hip joint replacement.Methods A total of 94 ASA Ⅰ ～ Ⅱpatients undergoing hip surgery with combined spinal epidural anesthesia(CSEA) were selected and randomized into 4 groups:Group M received a single epidural injection of 2 mg Morphine for analgesia,Group MN1 received an epidural injection of 1 mg Morphine combined with lumbosacral plexus block,Group MN2 received an epidural injection of 2 mg morphine combined with lumbosacral plexus block,and Group N received lumbosacral plexus block.All patients were administered intramuscular parecoxib for 3 days after surgery and,if the visual analogue scale(VAS)≥4,additional intramuscular tramadol.Patient-controlled intravenous analgesia(PCIA) was applied if pain relief was insufficient after Tramadol treatment.Postoperative analgesic effects,the ability to ambulate and side effects were monitored.Results VAS scores gradually increased in the 4 groups after surgery and were higher between the morning of the 1st day and the evening of the next day than at 4 hours after surgery in all the 4 groups.There were no significant differences in VAS scores between rest and exercise conditions in any of the 4 groups.Ambulatory VAS scores were lower in Groups MN1 and MN2 than in Groups M and N 6 hours after surgery,while resting VAS scores had no significant differences between the 4 groups.Resting and ambulatory VAS scores were both lower in Groups MN1 and MN2 than in Groups M and N 6 hours after surgery,while they had no significant differences between either Groups MN1 and MN2 or Groups M and N 4-8 hours after surgery.Resting and ambulatory VAS scores were lower in Groups M,MN1 and MN2 than in Group M on the morning of the day after surgery,and more patients in Group N needed early tramadol and PCIA for rescue analgesia.Muscle strength was lower in Groups MN1 and MN2 than in Groups M and N 4 hours and on the morning of the day after surgery.No significant differences between the groups were found in standing ability 6 hours after surgery and in motor activity on the morning of the day after surgery.The incidence of urinary retention was higher in Groups M and MN2 than in Groups MN1 and N,and was higher in Group MN1 than in Group N.The incidence of pruritus was higher in Groups M and MN2 than in Group N.There was no significant difference in Ramsay sedation scores and postoperative nausea and vomiting (PONV) between the groups.Conclusions Epidural morphine combined with lumbosacral plexus nerve block can provide better analgesic effects than a single dose of epidural morphine or lumbosacral plexus nerve block in elderly patients undergoing hip joint replacement.Although the synergy of the combination has certain influence on early muscle strength recovery,it does not affect early postoperative rehabilitation training.With the combined use of parecoxib and lumbosacral plexus nerve block,epidural injection of 1 mg and 2 mg morphine provides similar analgesic effects,but epidural injection of 2 mg morphine results in a higher incidence of urinary retention.Thus,a small dose of epidural morphine combined with lumbosacral plexus nerve block is recommended for postoperative analgesia in elderly patients receiving hip joint replacement.

Objective To discuss prevention and treatment of the late complications of deteniaceacal-colon continent urinary reservoir. Methods 105 patients who underwent detenia ceacal-colon con-tinent urinary reservoir were followed up for 9 -82 months(mean 40.5 months).Clinical data of these wereretrospectively analyzed. Results Late complications occurred in 25.7%(27/105) of the cases and 9were treated with operations,including difficulty with catheterization in 4 cases(3.8%),3 treated with dila-tion and 1 with efferent limb reconstruction with ileal,urinary pouch stones in 5(4.8%),4 treated with li-thotomy,urinary pouch perfotation in 1 (0.95%),treated with repair,urinary pouch superdistention in 1(0.95%),treated with reduction, single or double lateral hydronephrosis in 8(7.6%),caused by strictureof single or double lateral lower ureters in 4 (2 treated with excision lesion and anastomosis ) and by refluxin 1,1 case suffering from azotemia preoperatively worsened to uraemia treated with regular haemodialysis,hyperchloremia in 7 (6.7%),only 1 needed drugs treatment,repeated urinary infection in 11,amomg them,10 were complicated by the other complications,all treated with sensitive antibiotic. Conclusions Most ofpatients underwent detenia ceacal-colon continent urinary reservoir had good curative effects. Late complica-tions afflicting these patients mostly had immediate or mediate relations with symptomatic urinary infection.Prevention and treatment of symptomatic urinary infection can reduce the occurrence of late complications ofthis operative method,regular and adequant pouch washing and catheterization is efficient to prevention oflate complications of this operative method.

BACKGROUND: Ghildren refractory clubfoot includes idiopathic multiple contracture, untreated idiopathic clubfoot in older children and failure cases of repeated operations. It is very difficult to treat this type of children patients. It has important significance in the exploration of new therapeutic methods.OBJECTIVE: To improve the therapeutic effectiveness of refractory clubfoot in children with Ilizarov method.DESIGN: a self-controlled study.SETTING: Department of Orthopedics, Nanjing Children' s Hospital, Nanjing Medical University.PARTICIPANTS: Totally 3 cases of children idiopathic multiple contracture, 2 cases of idiopathic clubfoot in children aged more than 10 years old without treatment and 6 cases of postoperative recurrent idiopathic clubfoot were admitted by the Department of Orthopedics of Nanjing Children' s Hospital Affiliated to Nanjing Medical University during 1999 to 2000. All cases manifested abnormal ankylosis and shortening deformity in foot.METHODS: Twelve refractory clubfeet in eleven patients were treated with the Ilizarov method. After achilles tendon lengthening and posterior release,kieschner' wires or olive wires with tension were penetrated through multiple planes of the middle lower 1/3 of tibia, calcaneus and the 1st to the 5th metatarsals, which were fixed respectively to external bone fixer of a ring,half-ring or horseshoe shape and connected with each other by multiple screw bars into a three-dimensional external bone fixing set. Plantarflexion, inversion, adduction and shortening deformities were corrected by the adjustment of the distance between each part of the external bone fixing set through extension, compression, and rotation, etc., and navicular and cuboid osteotomy.MAIN OUTCOME MEASURES: All 11 cases were followed up for 2 to 10 years with an average period of 4. 5 years. Indices like foot morphology,talocrural articualr activity range and deformity correction were observed during the follow up.RESULTS: The results were excellent in 5 cases (6 feet), good in 4 cases (4 feet), fair 2 cases(2 feet) according to the Garceau standard scale. The rate of excellent and good clinical results was 83.3%. Mild forefoot adduction was left in 2 feet of 2 cases and quite obvious tarsal articular ankylosis was found in 4 feet of 4 cases; however, there were no significant differences of gait and load bearing between these patients and normal children.CONCLUSION: The Ilizarov technique is a safe and effective method for the treatment of refractory children clubfoot while its indications should be controlled strictly.

Objective To investigate the feasibility and effectiveness of fast track surgery (FTS) in neurosurgery. Methods One hundred fifteen patients who underwent neurosurgery surgery in Henan Province People's Hospital from June 2012 to March 2014 were enrolled in this study. All the patients were divided into FTS group (62 cases) and the tra?ditional operation group (53 cases). The clinical index, postoperative hospital stay and hospitalization cost were compared between the two groups. Results The clinical index were significantly lower in FTS group than in traditional operation group (P<0.05). Length of hospital stay (days) and hospitalization cost of FTS group were significantly shorter and lower in FTS group compared with traditonal operation group (8±1 vs. 11±2 days and RMB 4.58 ±0.75 vs. 5.78 ±0.64 ten thou?sand, respectively) (P<0.05). Conclusion FTS in neurosurgery operation is an all-new concept for surgery which can ef?fectively reduce postoperative complications, shorten length of hospital stay, decrease hospitalization cost and promote postoperative recovery.
