Objective To investigate the scope of application of precise hepatectomy and its value.Methods The clinical data of 112 consecutive patients with liver neoplasm who received hepatectomy at Renji Hospital from November 2006 to March 2009 were retrospectively analyzed.Precise hepatectomy technique was applied to 88 patients(precise group),whereas pringle maneuver was applied to the rest 24 patients(prince group).Patients in precise group had undergone lobectomy,segmentectomy or local resection,while patients in pringle group received segmenteetomy or local resection.The perioperative conditions of patients in the 2 groups were compared via Fisher exact probability and l test.Results No perioperative mortality,hepatic failure,reoperation due to massive hemorrhage or bile leakage was observed.The blood transfusion rate,blood loss,postoperative total bilirubin(Tbil),prothrombin time(PT)were 7%(2/29),220 ml,20 μmol/L,13 seconds in patients who received segmentectomy and local resection in precise group,and were 4%(1/24),210 ml,19μmol/L and 13 seconds in patients who received segmentectomy and local resection in pringle group,with no significant difference(t=0.248,0.263,0.246,P>0.05).The operation time,postoperative white blood cell (WBC)count.alanine aminotransferase(ALT)value and fever incidence were 60 minutes,7.5×10~9/L,66 U/L,10%(3/29)in patients who received segmentectomy and local resection in precise group,and were 15 minutes,14.0×10~9/L,335 U/L and 42%(10/24)in patients who received segmentectomy and local resection in pringle group,with significant difference(t=4.962,4.961,4.959,P<0.05).In precise group,the blood transfusion rate,postoperative WBC count,ALT value.PT and fever incidence were 9%(4/45),8.3×10~9/L,153 U/L,17 seconds and 13%(6/45)in patients who received Iobectomy,and were 12%(5/43),8.2×10~9/L,133 U/L,14 seconds and 14%(6/43)in patients who received segmentectomy or lncal resection,with no significant difference (t=1.652,1.225,1.236,P>0.05);the blood loss,operation time and postoperative Tbil level were 350 ml,250 minutes and 32μmol/L in patients who received lobectomy.and were 240 ml,150 minutes and 21 μmol/L in patients who received segmentectomy or local resection(t=4.915,4.967,4.829,P＜0.05).Conclusions Precise hepatectomy can decrease damage to patients,but it should be applied in selected patients according to the tumor location and the excision range.Precise hepatectomy is recommended to be applied in lobeetomy.

Objective To explore the liver toxicities of the VDLD scheme in children with malignant tumor.Methods In a prospective trial,the levels of serum total protein,albumin, globulin,rate of albumin/globuin alanine aminotransferase,aspartate transaminase,gamma glutamyltranspeptidase,total bile acid and alkaline phosphatase were tested in children with malignant tumour before and after VDLD scheme,and compared with each other.Results The concentration of the serum total bile acid was significantly increased after VDLD scheme than before(P

Objective To investigate the variations of surface protein genes of avian influenza virus (AIV)before and after infecting mouse.Methods Mouse lung tissue was infected with A/Goose/Guangaong/NH/2003(H5N1)and the virus was isolated 12 hours and 9 days after replication in lung tissue of mouse.The isolated strains were amplified in embryonated chicken eggs,anti the virion RNA was transcribed into cDNA by reverse transeriptase.After amplification and purification,dideoxy-mediated chain termination was performed to detect synthetic oligonucleotide primers and DNA sequence was analyzed.Results The homology of nucleotide sequence for HA gene of three isolated strains was 99.6%-99.8%.and that of amino acid sequences was 99.3%-99.6%.The homology of nucleotide sequence for NA gene of three strains was 99.8%-99.9%.all of them were synonymous mutatinns.No variation was found in M gene.Conclusion After replication in mouse lung tissue,no significant mutation was found in the surface protein genes of AIV except some point mutations in HA genes.

Objective To compare the effect of titanium elastic nailing (TEN) and plating in treatment of both radius and ulna fractures in children older than 10 years.Methods This retrospective analysis comprised 38 children (50 sides) of both radius and ulna fractures treated with TEN (30sides) or plate (20 sides) between 2009 and 2014.Parameters compared between the two fixation methods were operation time,ratio of open/close reduction,time to internal fixation removal,incidence of postoperative complications,and bone union time.Anderson score was used to evaluate the treatment results.Results Operation time [(94.3 ± 39.5) min vs (120.5 ± 45.4) min],time to internal fixation removal [(210.8 ± 84.1) d vs (264.4 ± 88.9) d],and ratio of open/close reduction (20/10 vs 20/0)varied significantly between TEN and plating groups (P ＜ 0.05 or 0.01).Whereas,no statistically significant differences were noted in regard to complication rate,bone union time,and effect evaluation.Conclusion For fracture of the radius and ulna in children older than 10 years,TEN should be used for closed type without obvious displacement,but plate fixation is associated with lower incidence of fracture malunion and better outcome in treatment of open type with obvious displacement.

Objective To evaluate endoluminal repair and preoperative management for acute Standford type B aortic dissection complicating massive hydrothorax. Methods The clinical data of 27 patients (23 males, 4 females) hospitalized from January 2003 to December 2008 were analysed retrospectively. The average age was 47 ±9 years (35 ～70). Eleven patients had bilateral huge hydrothorax (40. 7% ) , while 13 had left hydrothorax (48. 1% ) and 3 had right hydrothorax (11. 1% ) only, and in 2 of them with additional pericardial effusion (7.4% ). SaO2 was below 90% in all cases. All patients underwent emergency endovascular repair. For control of massive hydrothorax found by CT or chest fluoroscopy, puncture drainage or tube drainage were administrated postoperatively. Results All the 27 operations were successful, and there was no perioperative mortality. Three type Ⅰ and one type Ⅳ endoleaks occurred but disappeared in one month. Hydrothorax disappeared 28 days to 3 months postoperatively in all patients, of which 5 cases had puncture drainage (18.5%) and 1 case had tube drainage ( 3. 7% ). Mean follow-up was 30 ± 20 m ( 6 ～ 78 m ) after endovascular management. Complications included pleural thickening (6 of 27, 22. 2% ) , pulmonary atelectasis (2 of 27, 7. 4% ) , and lung consolidation combined with chest dent (2 of 27, 7. 4% ). Conclusions Emergency endovascular therapy is safe and effective for acute Stanford type B aortic dissection with massive hydrothorax. Drainage of hydrothorax after stent-graft deployment is a must for the patient suffering from severe respiratory failure.

Objective To identify the differential serum proteins in patients with hepatic injury resulting from coal-burning type of arsenism. Methods Six serum samples were collected from patients with liver injury resulting from coal-burning type of arsenism and healthy subjects(control gruop) in endemic arsenism area. Twodimensional gel electrophoresis(2-DE) was performed to separate serum proteins, after silver staining, the differential expression of proteins were analyzed and then identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE map of serum protein patterns of patients and normal control were established successfully. The results showed that there were an average of (824 ± 31 ) spots and (782 ± 42) spots on 2-DE matching of the patients and control groups and the matching rate was 94.9%(782/824). From these two groups 49 differential protein spots were identified, of which over 3 times the difference in the expression of 30 protein spots were singled out and MALDI-TOF-MS analysis was carried out. Ten proteins were identified. Upregulated expression was observed in alpha-2-macroglobulin, B-cell receptor-associated protein, keratin 1,apolipoprotein A-I, and down-regulated expression was observed in haptoglobin, α2-heremans-schimid-glycoprotein,mitogen-activated protein kinase 4, zinc finger protein 323, ZAP-70 and SP40 in the patient group. Conclusions The well-resolved and reproducible 2-DE serum patterns of patients are established and some differentially expressed proteins are characterized. Whether these proteins of differential expression are serum markers for liver injury resulting from coal-burning type of arsenism need to be further verified.

Objective To summarize the experiences in using Bio-Gide and Bio-Oss for guided bone regener- ation in dental implantation.Methods In 28 cases of bone deficiency,Bio-Gide membranes were applied to cover alveolar defects filled with the Bio-Oss bone powder.In postoperative periodic follow-.up,the bone regeneration effect was observed by successive clinical and X-ray examination.Results 38 implants were inserted in the 28 patients and Bio-Gide membranes were used in the sites of the 38 implants.Alveolar bone defects were filled with new bone in 27 patients,1 implant loosed because of inflammation.37 implants had ideal osseointegration at stageⅡsurgery and were prosthetic rcconstructed successfully.No implant loosed during the observed period of 15 months to 4 years. Conclusion Bio-Gide and Bio-Oss have ideal effect of guided bone regeneration in dental implantation.

Objective To explore the clinical characteristics and prognosis of congenital pulmonary artery sling (PAS) in children. MethodsThe clinical data of 38 children diagnosed with PAS during June 2009 and February 2015 were retrospectively analyzed. ResultsIn 38 PAS children, 35 cases (89.47%) were hospitalized for varying degrees of respiratory manifestations with recurrent cough (89.47%) and wheezing (84.21%) being the most common. The remaining 3 cases were found abnormal in routine preoperative examination and the diagnosis was confirmed after further examination. All 38 children were performed computer tomography angiography (CTA). Thirty-seven cases were diagnosed of PAS and diagnostic rate was 97.37%. One case was suspected of pulmonary dysplasia and diagnosed of PAS after operation. Twenty-six children received surgical treatment, of whom 25 children had pulmonary artery reconstruction (LPA). Seven children died during/after operation and 18 survived. The remaining 12 children received non-surgical treatment, of whom 9 died and 3 survived.ConclusionCardiac uhrasonography may reveal PAS in the early stage, while CTA is the best method for conifrmed diagnosis. LPA reconstruction is an important means of relieving left pulmonary artery oppression.
