OBJECTIVE:To observe clinical efficacy and safety of capecitabine and tegafur gimeracil and oteracil potassium synchronous radiotherapy in the treatment of recurrence after radical resection of colon cancer. METHODS:A total of 150 patients with recurrent after radical resection of colon cancer in our hospital during Jan. 2012-Dec. 2012 were divided into group A and B ac-cording to random number table,with 75 cases in each group. Both groups received three-dimensional conformal radiotherapy. Group A was additionally given capecitabine 2.5 g. Group B was additionally given tegafur gimeracil and oteracil potassium,40 mg,bid for body surface area <1.25 m2,50 mg,bid for body surface area ranged 1.25-1.50 m2 and60mg,bid for body surface ar-ea<1.50 m2. Clinical efficacies of 2 groups were compared;1-year,2-year,3-year survival andⅢ-Ⅳdegree toxic effect were fol-lowed up. RESULTS:The total response rate of group B was 86.67％,which was significantly higher than 66.67％ of group A, with statistical significance(P<0.05). 1-year,2-year,3-year survival rates of group B were 93.335,72.00％,58.67％,which was significantly higher than 74.67％,53.33％,41.33％,with statistical significance(P<0.05). The median disease progression time of group A was 8.0 months,which was significantly shorter than 9.5 months of group B,with statistical significance (P<0.05). There was no statistical significance in Ⅲ-Ⅳ degree toxic effect between 2 groups (P<0.05). CONCLUSIONS:Compared with capecitabine,tegafur gimeracil and oteracil potassium combined with three-dimensional conformal radiotherapy show significant therapeutic efficacy for recurrence after radical resection of colon cancer,can control disease progression,prolong the survival time and don't increase the risk of toxic effects.

Objective To evaluate the overall failure rate of one or two-stage exchange arthroplasty for infections in total knee arthroplasty (TKA) and the predictors affecting the outcome of exchange.Methods Thirty-nine cases received one or two-stage exchange arthroplasty for periprosthetic joint infections after primary TKA in Shanghai Sixth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine and Southeast Hospital affiliated to Xiamen University from January 2012 to November 2014 were reviewed.Periprosthetic tissue and articular fluid of all patients were analyzed by bacterial culture.All patients were followed up for more than one year.C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),procalcitonin (PCT) and blood routine were tested every four weeks,and the evaluation on pain,total periprosthetic function,range of motion and deformation of arthroplasty were conducted.Differences between groups were analyzed using chi-square test or Student's t test when appropriate.A stepwise selection approach in logistic regression analysis was used to screen key predictors for outcome of one or two-stage exchange for infections in TKA.Results There were 39 patients who had undergone one or two-stage exchange for infections in TKA,including 20 males (51.3％) and 19 females (48.7％) with an average age of (62.4±11.7) years.Among the 39 patients,18 gram-positive strains were isolated from specimens,and 6 gram negative strains,2 Mycobacterium tuberculosis and 1 candida albicans.Ten of 39 reimplantations developed reinfection.Between the success and failure groups,there were significant differences in the time from primary TKA to revision (P =0.023),operative time (P =0.029),multidrug resistant organisms (P =0.045),the preoperative and post-operative ESR (P=0.002 and P＜0.001,respectively) and post-operative CRP (P=0.018).Multivariable logistic regression analysis demonstrated that time from primary TKA to revision (OR =0.96,95％CI:0.92-1.00,P=0.025),preoperative ESR (OR=0.97,95％CI:0.95-1.00,P=0.045) and post-operative ESR (OR =0.94,95％ CI:0.91-0.98,P =0.002) were independent indicators associated with the outcome of one or two-stage revision.Conclusions The failure rate after revision for infected TKA is relatively high.The time from primary TKA to revision,preoperative and post-operative ESR could predict the outcome of one or two-stage revision effectively.

BACKGROUND: Effect of acellular surfactant and biological safety of bone graft materials highly correlated with selection of surfactant; therefore, a novel compound surfactant was used to prepare acellular bone graft materials in this study. OBJECTIVE: To evaluate acellular effect and biological safety of bio-derived bone tissue treated by a novel surfactant in order to obtain a safe and reliable bone graft material. METHODS: Surfactant was prepared with anionic surfactant sodium dodecyl benzene sulfonate (ABS), anionic surfactant sodium fatty alcohol ether sulfate (AES) and distilled water at the ratio of 13:7:80. Fresh bovine cancellous bone and surfactant which was used to remove cells and lipid by two-step flow were used to prepare a novel bio-derived bone graft material. The histological and microscopic observations of microstructure were made. Also acute body toxicity test, hematolysis experiment, cell toxicity test and biological safety were assessed on surfactant-treated bio-dedved bone graft material (STBB). A long-term animal experiment was conducted to observe the biocompatibility and biodegradability of STBB. The ultraviolet dispersion of light luminosity method was employed to measure the residual amount of surfactant in STBB. RESULTS AND CONCLUSION: STBB was a whitish porous cancellous bone. No cell was found in bone lacuna, bone canaliculus was empty, and the collagen fiber had an order arrangement. Acute body toxicity test was qualified according to GB/116886.11-1997 standard, hematolysis experiment was < 5%, and cell toxicity test was grade 0, confirming that STBB was safe. The remaining surfactant in STBB was lower than 0.1 g/L. The long-term animal experiment demonstrated that fiber was present at 4 weeks, bone lacuna had cellular growth and the fusion of STBB and host appeared. The STBB was partial absorbed by organism at 8 weeks and completely absorbed at 24 hours. The results indicated that STBB had an excellent biocompatibility and biodegradability. As a new bone implant material, STBB was safe and dependable for transplantation.

Objective To investigate the effects of fast-track surgery on postoperative rehabilitation of patients with liver cancer. Methods Forty-one patients with liver cancer who had been admitted to Zhongshan Hospital of Fudan University from 9 to 30 in July 2008 were randomly divided into fast-track surgery group (n =20) and routine treatment group (n =21) according to the random number table. Patients in fast-track surgery group were preoperatively educated in order to lessen their anxiety. Bowel preparation was not applied before operation, and they were orally administered with 1000 ml of enteral nutrition emulsion (1300 kcal), then they were fasted for 4 hours before operation. Urethral catheter and gastric tube were removed after operation. They were orally administered with 1000 ml of enteral nutrition emulsion on postoperative day 2, and were encouraged to partake in off-bed activity shortly after the operation. The off-bed time, anus exhaust time, postoperative complica-tions, hospitalization time, expense, nutritional and metabolic indexes on postoperative day 1, 3 and 5, hepatic and renal function, immune and stress indexes between the 2 groups were compared by t test and chi-square test. Results There were significant differences in off-bed time, anus exhaust time, patients' weight, expense, total bilirubin level on postoperative day 1, 3 and 5, and level of serum TNF-α on postoperative day 3 between the 2 groups (t =7.065, 5.483, 3.754, 2.291,2.289, 3.218, 3.192, 2.434, 2.089, P <0.05). Conclusions Fast-track surgery can accelerate the postoperative rehabilitation of patients with liver cancer.

Objective Tamm-Horsfall protein (THP) may play a role in kidney stone formation.The article aimed to conduct a preliminary study on the role of THP in kidney stone formation by investigating the changes of THP in rat urine, pathological changes of renal tissue and the formation of calcium salt crystals after establishing CNPs rat model of kidney stones.Methods Stone samples of 40 patients from February to June 2015 in our department were collected to establish the model of CNPs-induced kidney stone in rats and prepare CNPs suspension.48 SD rats were randomly divided into experimental group (group A) and blank control group (group B).Group A were injected with CNPs and the same amount of sterile saline injection in the group B.The urine of rats was collected after injection at 3h, 6h, 12h, 24h, 1w, 2w, 4w and 8w.ELISA were applied to detect THP levels in the urine.Then the rats were killed to take the kidney tissue.HE staining was used to investigate the pathological changes of the cells and evaluate the formation of the calcium salt crystals.Results THP levels in group A at 24h, 1w, 2w, 4w and 8w ([166.03±3.02], [173.50±1.78], [174.55±2.05], [176.54±2.45], [177.11±1.76]pg/mL) were significantly higher than that at 3h(165.89±2.23pg/mL)(P<0.05), which was the same case in comparison with those of group B ([157.65±2.22], [156.54±1.43], [159.45±3.21], [158.63±2.98], [157.33±2.05]pg/mL).Compared with the calcium salt crystal score at 6h (1 point), the scores at 3,6,12,24h (average score 2 points) increased.At 2w the score increased significantly to 3 points and reached the top score(6.7points) at 8w, which was of significant difference.The score of calcium salt crystals was in positive correlation with THP content (r=0.843,P<0.05).Conclusion THP in urine may contribute to the aggregation of calcium salt crystals and the formation of kidney stones.

Objective To improve the knowledge of the diagnosis and treatment of functional insulinoma. Methods The clinical data of 12 cases of functional insulinoma in China-Japan Union Hospital of Jilin University from 2000 to 2009 were analyzed retrospectively. Results For the 12 cases of functional insulinoma, preoperative fasting blood glucose and the positive rate of insulin were 92% and 89% respectively. The positive rate of IRI/G and C-Peptide reached 100%. The accuracy of the niveau diagnosis of preoperative abdomen ultrasound, CT and of MRI were 75%, 36% and 0% respectively; whereas the accuracy of localization of intraoperative palpation combined with ultrasonography reached 100%. The result of glucose increased by one time within one hour after excision and the rest excision. In the 7 follow-up cases, the symptom of hypoglycemia was not found. There were 3 cases of pancreatic fistula after operation. Conclusions For the suspected cases of functional insulinoma, the measurement of IRI/G and C-Peptide are needed besides measuring blood glucose and insulin. Intraoperative palpation and ultrasonography are effective methods of the localization of functional insulinoma. The complete resection of the insulinoma can be assessed by monitoring the change of the blood glucose after excision as well as the rapid intraoperative pathological examination.
