Objective To investigate the effects of nutritional support on the hypermetabolism of patients with digestive tract fistula complicated with severe abdominal infection. Methods Twenty-nine patients with digestive tract fistula complicated with severe abdominal infection were administered parenteral nutrition (PN) for 4 to 8 days, and then followed by enteral nutrition (EN) or EN + PN. The body weight, serum albumin, transferrin, prealbumin, fibronectin were monitored before and on the 10th and 28th day after nutritional support. Results The levels of serum prealbumin and fibronectin were increased significantly on the 10th day after nutritional support (t = 3.72, 3.52, P <0.01). The body weight, the levels of serum albumin, transferrin, prealbumin and fibronectin were significantly higher than those before nutritional support (t=3.97, 6.57, 7.09, 3.51, 3.58, P<0.01). Conclusion Nutritional support is effective in alleviating hypermetabolism of patients with digestive tract fistula complicated with severe abdominal infection.

Tag, similar to a keyword and belonging to a non-controlled term, is a marking language, and can be freely marked by its users, thus playing a role in organization of information resources.Social tagging, a tag created by network users and added to the resources they concerned, has become one of the important methods for the network information resources organizing system to organize and mange resources.Suggestions were thus put forward in this paper for improving the information retrieval function of future social tagging system by comparing its 3 functions and assessing its efficiency.

Objectives:To observe the influence of PN treatment on the postoperative patients of advanced ovarian cancer. Methods:The patients were divided into two groups.Thirty cases of patients(PN group) were treated with PN after the operation for the ovarian cancer.Thirty five cases of patients(control group) were treated regularly without PN.The biochemical indicators,complications and mortality rate were compared between the two groups. Results:The biochemical indicators in PN group were better than those in control group.The incidence of complications and mortality rate in PN group were significantly lower than those in control group. Conclusions:PN can improve the general status of postoperative patients with advanced ovarian cancer and decrease the complication incidence and motality rate.

Objective To observe the effect sling exercise therapy (SET) and Tuina on radicular cervical spondylosis. Methods From August, 2015 to December, 2016, 72 patients with radicular cervical spondylosis were randomly divided into control group (n = 36) and trial group (n = 36), who accepted traction and SET+Tuina, respectively, for four weeks. They were measured F-wave conduction velocity with electromyogram from median nerve and ulnar nerve, somatosensory evoked potential (SEP), and current perception threshold (CPT) before and after treatment. The clinical ratio of improvement was calculated. Results The ratio of improvement was 83.33% in the trial group more than 58.33% in the control group (Z = 2.093, P < 0.05). F-wave conduction velocity increased in both groups after treatment (t > 12.059, P < 0.001), and increased more in the trial group than in the control group (t > 3.266, P < 0.01); while the latency of SEP decreased in N9 and N13 in both groups (t > 7.061, P < 0.001), and decreased more in the trial group than in the control group (t > 8.033, P < 0.001); the grade of CPT decreased in both groups (t > 8.895, P < 0.001), and decreased more in the trial group than in the control group (t = 8.913, P < 0.001). Conclusion The combination of SET and Tuina can promote the repair of nerve conduction of cervical spondylotic radiculopathy.

Objective To investigate the methods and techniques for organ procurement from donation after cardiac death (DCD),and to evaluate post-transplant outcomes.Methods In this retrospective study,clinical data of 26 cases of DCD organ procurements were analyzed through either epigastric multivisceral organ harvesting or solitary organ harvesting.Results Twenty livers,44 kidneys and 2 multivisceral grafts were procured,followed by 24 cases of liver transplantation,42 cases of kidney transplantation,and 2 cases of multivisceral transplantation.The operations were successful and all transplanted organs were satisfactorily recovered with no primary nonfunction or other complications observed.Conclusion Our methods and techniques for organ procurement from DCD donors require experienced surgery skills,while can maximatily shorten donor organ ischemic time,guarantee procurement of high quality of organs and ensure a favourable transplant outcomes.

OBJECTIVETo evaluate the local recurrence and 5-year survival of proximal fibular osteosarcoma.

METHODSFrom October 1997 to July 2005, 12 patients with proximal fibular osteosarcoma were treated. There were 9 males and 3 females. The mean age at diagnosis was 16 (9-23) years old. Histopathological diagnosis were obtained by trut-cut biopsy, Enneking surgical stages of 12 lesions were as follows: 11 grade II B and 1 grade III. Induction chemotherapy was applied to all patients except one who left the hospital after the biopsy. Of 11 patients, 8 were performed Malawer type I resection, and 3 type II. All patients continued to get postoperative chemotherapy.

RESULTSRegular follow-up was applied. Only 1 patient was found local recurrence one year after operation and received re-resection, the others did not. Four patients died of lung metastases, including the one who did not get treated, one stage III and two II B patients. The range of follow up was 6 to 117 months. The evaluated 5 year disease-free survival of 11 patients who got treated was 72.7% by using Kaplan Meier survival analysis.

CONCLUSIONSThe local recurrence is low, and 5 year disease-free survival is acceptable, in accordance with present point that marginal resection may not impact survival for fibular osteosarcoma. No knee instability is found in this group after great care is taken for proper reconstruction of lateral collateral ligament and reinsertion of biceps femoris tendon on the lateral condyle of tibia.

OBJECTIVEThe purpose of the study was to investigate the content of nickel (Ni) ion in patients' saliva after wearing the porcelain-fused-to nickel-chromium (Ni-Cr) crown or the porcelain-fused-to nickel-chromium-titanium(Ni-Cr-Ti) crown.

METHODS50 patients who had one molar or premolar needed repairing were selected and divided into two groups randomly. Patients in one group were fabricated with porcelain-fused-to Ni-Cr crown and the patients in the other group were fabricated with porcelain-fused-to Ni-Cr-Ti crown. Collect the patients' saliva before wearing, 1 week, 3 months, and 6 months after wearing. The content of Ni ion in saliva was detected by inductively coupled plasma mass spectrometry (ICP-MS).

RESULTSThe content of Ni ion in both groups increased at the first week, and go back after 6 months. There were no significant differences before wearing, 1 week, 3 months, and 6 months after wearing. There were no significant differences between the two groups.

CONCLUSIONWearing the porcelain-fused-to Ni-Cr crown or the porcelain-fused-to Ni-Cr-Ti crown has no significant influence on the content of Ni ion in saliva.

Objective To evaluate the diagnosis and treatment of early-stage hepatic artery thrombosis(HAT) after adult liver transplantation.Methods387 consecutive adult patients who underwent liver transplantation from June 2007 to October 2010 by the same surgery team in the Transplant Center,First Affiliated Hospital of Sun Yat-sen University were retrospectively studied.Hepatic arterial blood flow was monitored by color Doppler ultrasound (DUS) daily during the first week after transplantation.Ultrasonic contrast or hepatic artery angiography was performed on recipients with suspected HAT.Results10 patients developed HAT on 7(2-18)d after operation.The incidence of HAT was 2.6％ (10/387).Interventional therapy was performed in 2 patients with one patient who received a stent because of hepatic artery stricture.Three patients underwent emergent hepatic artery revascularization combined with intra-arterial urokinase thrombolysis treatment.One developed a rethrombosis and died.The remaining 2 patients received re-transplantation.Three patients died of liver failure and severe infection.The mortality rate was 40％ (10/387).ConclusionsIt is essential to diagnoses HAT by monitoring the artery flow by Doppler ultrasound screening in the early period after operation.Interventional therapy,emergent hepatic artery revascularization and re-transplantation are effective rescue treatments.Prevention of HAT is most important.

Objective To explore the effect of different cold ischemia (CI)times on the patterns of intra-graft T cell activation gene-3 (TCA-3) expression early after isogeneic half liver transplantation (PLT)in mice. Methods The models of C57BL/6 full-size(FS) and PLT were established.The CI time was 1,4 and 8 h.Specimen were collected at 4 and 24 h post-reperfusion.Ribonuclease protection assays (RPA)was used to evaluate serial mRNA expression of the TCA-3 chemokine in all mice.Histopathology was used to examine cold ischemia injury in the liver grafts. Results A total of 45 control and 30 PLTs were performed.The survival rate at 7 day after control and PLT was 100％.Quantitative analysis demonstrated the levels of TCA-3 mRNA expression were low at 4 h after reperfusion in control group with 1,4,8 h CI.The levels of TCA-3 significandy increased at 4 h after reperfusion in PLT group with CI of 1,4,8 h and the difference between the two groups was statistically significant ( F =7.41,P ＜ 0.05 ). TCA-3 mRNA expression significantly decreased at 24 h after reperfusion in two groups. But the difference was not statistically significant ( P ＞ 0.05 ). Histopathology showed severer cold ischemia injury in PLT grafts compared with control grafts. Conclusions The expression of TCA-3 significandy increased early after PLT and played an important role in cold ischemia injury.TCA-3 could be used as the early therapeutic target for reducing ischemia injury in PLT grafts.
