OBJECTIVETo investigate the clinical efficacy of cannulated screw fixation with percutaneous Poking reduction for the treatment of Sanders II, III calcaneal fracture.

METHODSFrom January 2012 to January 2014, 19 patients with Sanders II, III calcaneal fracture were treated with cannulated screw fixation with percutaneous Poking reduction. There were 14 males and 5 females, ranging in age from 19 to 58 years old, with an average age of (38.3 +/- 4.1) years old. The changes of Bohler angle and Gissane angle were measured and compared preoperatively and postoperatively to observe the recovery of the articular surface. The Maryland Foot Score was used to evaluate operation outcomes.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months with a mean of (22.3 +/- 5.3) months. The Bohler angle and Gissane angle were improved significantly after operation compared with those before operation (P < 0.05). The Maryland score was 83.2 +/- 8.4.

CONCLUSIONTreatment of calcaneal fractures with screw fixation with percutaneous Poking reduction has several advantages such as satisfactory outcome,less damage, fewer complications, quicker recovery, and shorter hospital stay,and it is one of the effective treatments for Sanders II and III calcaneal fractures.

This article was aimed to study the mechanism of interaction between human serum albumin (HSA) and zinc ions, in order to provide the information on the secondary structure modification of HSA and the thermodynamics parameters using circular dichroism (CD) and isothermal titration calorimetry (ITC). CD and ITC were applied in the study. The concentration of HSA were 0.025 mmol·L-1, 0.05 mmol·L-1, 0.1 mmol·L-1, and 0.2 mmol·L-1, respectively. The concentration of zinc ion was 5 mmol·L-1. The CD analysis revealed that the secondary structure modification of HSA differed depending on the concentration of HAS. And the content ofα-helix was inversely proportional to the concentration of HSA. When the concentration of HSA was 0.2 mmol·L-1, the content ofα-helix was special. A series of thermodynamics parameters including association constants (Kb), stoichiometry (N), entropy (ΔS) and enthalpy (ΔH) were investigated by ITC analysis. And two types of binding sites were observed when ZnSO4(mmol·L-1)?HSA (mmol·L-1)= 5?0.2. The secondary structure modification of HSA interacting with zinc ions depended on the concentration of HSA, a dramatic reduction ofα-helix was detected when the concentration of HSA attained 0.2 mmol·L-1. And the protein hydrophobicity reduction and peptide chains expansion were equally observed at this concentration. The ITC analysis also revealed endothermic and exothermic binding sites in the ZnSO4-HSA interaction when ZnSO4 (mmol·L-1)?HSA (mmol·L-1)= 5?0.2, indicating that the endothermic sites were specific but not preferential for zinc ions interactions. These results provided theoretical supports for the application of Zn2+ to open the endothermic sites of HSA.

Objective To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome,and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study.Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients,CT in 13 patients as well as MR in 3 patients.Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years).Results Serum HLA B27 antigen was positive in all patients. Both skin and bone abnornalities were found in all patients.Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints,anterior chest and limbs.Sacroiliac joints were asymmetrically involved with imaging features in all patients.Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients,CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling.MR imaging was able to depict edema changes that was not detectable by CT and radiography.Conclusion SAPHO syndrome is a rare disease,but for patients with skin and bone-joint abnormalities,especially with skin palmoplantar pustulosis,acne as well as with imaging features at the sacroiliac joint and anterior chest wall,SAPHO syndrome should be taken into a diagnostic consideration.

Objective To compare the prognosis and life quality of patients with early-stage breast cancer(stage I or II)undergoing breast-conserving surgery or modified radical mastectomy.Methods 180 cases with early-stage breast cancer were divided into 2 groups:breast-conserving surgery group(BCS)and modified radical mastcctomy group(MRM),with 90 cases in each group.The 2 groups were all given radiotherapy,chemotherapy and endocrine therapy according to indications.The prognosis and life quality in the 2 groups were compared.Results The 5-year-postoperative follow-up showed there was no significant difference in duration of disease-free survival(DFS)of the 2 groups.However,life quality of BCS patients was significantly better than that of MRM patients in terms of general health,physical function,pain,vitality,social functioning,emotion and mental health.Conclusion Breast-conserving surgery is highly recommended for patients with early-stage breast cancer.

OBJECTIVE To investigate the distribution of pathogens and their antibiotic resistance in lower respiratory tract infection(LRTI) from intensive care unit(ICU) in our hospital,and provide basis for rational selection of clinical drugs.METHODS Pathogens were detected from qualified sputum specimens in LRTI from ICU and identified by VITEK-AMS60 automatic microbial analyzing system.Drug susceptibility was determined by KB test.RESULTS From 320 sputum specimens 367 pathogens were detected between from Jan 2007 to Mar 2008,including 261 strains(71.1%) of Gram-negative bacilli,70 strains(19.1%) of fungi,and 36 strains(9.8%) of Gram-positive cocci.21.8% Of the isolated pathogens were Acinetobacter baumannii,with 16.7% of drug-resistant rate to cefoperazone/sulbactam and over 71% to other 13 antibiotic agents.The rate of extended spectrum ?-lactamases(ESBLs) producing Escherichia coli isolates and Klebsiella pneumoniae ones were 65.2% and 72.0%,respectively,comparing to 84.6% for meticillin-resistant Staphylococcus aureus(MRSA).CONCLUSIONS Gram-negative bacilli are the major pathogens of LRTI in ICU,in which A.baumannii shows with a high rate of drug-resistance,followed by fungi,which should attract the clinician′s more attention.

Objectives To evaluate the clinical value of neoadjuvant chemotherapy (NACT) in the treatment of local advanced cervical cancer. Methods We searched the clinical trials on the treatment of local advanced cervical cancer with NACT followed by surgery versus initial surgery on English and Chinese published literatures from the main medical data resources (MEDLINE, PUBMED, ELSEVIER ScienceDirect, CNKI). The data about positive pelvic nodes, interstitial infiltration, vascular invasion, positive surgical margin, 3-year overall survival (OS), 3-year disease-free survival (DFS), 5-year OS, 5-year DFS were extracted from these papers, and a meta-analysis was applied. Result The hazard ratio (HR) of positive pelvic nodes on NACT group versus control group was 0. 54(95% CI 0. 33 ～0. 86), HR of interstitial infiltration was 0. 45(95% CI 0. 24 ～0. 86), HR of vascular invasion was 0. 25(95% CI 0. 16 ～0. 38), all differences were statistically significant. And HR of positive surgical margin was 0. 45 ( 95% CI 0. 21 ～0. 99), P = 0. 05, which indicated the difference was not statistically significant. And there were also no significant difference on the HR of 3-year OS, 3-year DFS, 5-year OS and 5-year DFS, and their RR were 1.18(95% CI 0. 84 ～ 1.66) ,1.31 (95% CI 0. 96 ～ 1.78) ,0. 89(95% CI 0. 68 ～ 1.15) ,and 0. 99(95% CI 0. 71 ～ 1.93) respectively. Conclusion For local advanced cervical cancer, NACT could reduce pathological risk factors but it did not improve the survival.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.
