OBJECTIVE:To provide reference for the rational use of vancomycin in neonatal sepsis. METHODS:A retrospec-tive survey was performed for newborns with neonatal sepsis in our hospital from Sept. 1st in 2011 to Sept. 1st in 2012,and the pathogenic examination results,bacterial resistance and use of vancomycin were analyzed and summarized. RESULTS:Totally 317 strains of pathogens were detected in 202 cases,including 147 strains of G+ bacteria(46.4%),88 strains of fungus(27.7%)and 82 strains of G- bacteria (25.9%). Coagulase-negative staphylococcus was the main pathogens. The use rate of vancomycin was 47.0%(95 cases),and the drug selections were all based on susceptibility,with most of two-drug combination(68 cases). No se-vere adverse reactions were found. CONCLUSIONS:Coagulase-negative staphylococcus is severe and has multi-drug resistance in the cases of neonatal sepsis in our hospital. While,the use of vancomycin is basically rational. However,the clinical use of vanco-mycin should be more cautious to prevent the generation of vancomycin-resistant strains.

Objective To investigate the effect and perioperative nursing experience of surgical operation on patients with incomplete cervical spinal cord injury caused by traumatic cervical spine fracture. Method Fifty-nine patients with traumatic cervical spine fracture in our hospital from January 2011 to 2014 were nursed perioperatively, including before operation , training accttenty with swallowing and blowing balloons besides basic nursing care , and after operation , mental care , close observation and functional exercises postoperatively. Results The operation time was (110.5+13.0) min, the amount of bleeding was (155.6+7.5)mL. Three patients developed hematoma compression, 13 patients developed high fever. All patients were cured after treatment and nursing. Conclusion Preoperative training of swallowing and blowing balloon is fundamental for ensured surgical effect and intraoperative surgical cooperation and close observation together with postoperative mental care, close obsersation and functional exercise are the guarantee for surgical effect.

OBJECTIVE: To discuss the diagnosis and treatment of esophageal perforation induced by esophageal foreign body. METHOD: Ten patients, who were diagnosed as esophageal foreign body and esophageal perforation, were retrospectively analyzed. One patient was operated in other hospital and transferred to our department post-operation. The foreign bodies were removed through rigid esophagoscope in 7 cases and through the tracheotomy in 1 case. The last case was admitted into hospital for abscess around the esophagus. The foreign body wasn't find during the examination of rigid esophagoscope and the patient vomited out a glass foreign body after the surgery. RESULT: In all cases, there were three date stones, two button batteries, one metal gear, one pin, one metal cans pull ring, one glass plate, one arc hard plastic sheet. Seven patients were cured after conservative treatment, and restored normal diet. For the rest 3 cases, patients were cured after the repair operation of tracheoesophageal fistula. CONCLUSION The esophageal perforation must be highly suspected of the esophageal foreign body with a long history, sharp shape or corrosive foreign body. The esophageal radiography may be taken to obtain the final diagnosis. The patients diagnosed as esophageal perforation must be treated with antibiotics, nasal feeding or feeding by gastrostomy, and followed-up closely. Small perforation can heal after a period of time by nasal feeding, while tracheoesophageal fistula was needed to repaire after a period of time for restoring a good physical condition in most cases.

BACKGROUND:Many studies reported the relationship of the mechanical properties and water content about bone tissue, which is one of organizations containing the lowest water content on human body. Researches on effect of water on biological tribology behavior of bone tissue have been rarely reported and are the experimental study generally. OBJECTIVE:To explore the influence and the damage mechanism of water on biological tribology behavior of bone tissue, by comparing multiscale numerical model established with the experiment. METHODS:Dehydration of the bone tissue was studied by nanoindentation test and both reciprocating sliding and impact wear tests. A multi-scale finite element model was constructed under a flat-on-ball configuration. RESULTS AND CONCLUSION:The viscoelasticity and the tribological properties of bone tissue significantly decreased as well as the different wear mechanisms under applied loading after drying. The analytical results indicated that there were high stress condition, which incurred the micro-crack initiation and the appearance of peeling and wear, around the Haversian canal, circumferential lamellas and the interstitial tissues. Meso-scale:dehydration weakened the function of absorption and interruption of stress, which facilitated crack extension in pore. Micro-scale:the high stress gradient of structure of canaliculi and lacunae is an important cause of tissue damage.

Objective To study the efficacy of CPT-11 TACE in the treatment of unresectable HCC.Methods A retrospective review was undertaken on unresectable HCC patients receiving doxorubicin transarterial chemoembolization (59 cases) and irinotecan(CPT-11) in 24 cases from May 2003 to November 2011.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the two groups were assessed for statistical significance with the log-rank test.Results Overall survival time was significantly longer in patients treated with CPT-11 compared with doxorubicin treated group (21.7 vs 14.5 months,P =0.042).There was no significant difference in time to progression between the two groups,but time to progression was longer in CPT-11 group than doxorubicin treated group (11.42 vs 9.46 months,P =0.091).Subgroup analysis showed that for intermediate-stage HCC,CPT-11 resulted in a significantly longer time to progression and overall survival compared with doxorubicin treated group (P =0.029 and P =0.014,respectively).There were no significant differences in adverse events among the two groups (P ＞ 0.05).Conclusions Chemotherapeutic agent CPT-11 in the form of TACE significantly improved overall survival when compared with doxorubicin for the treatment of unresectable HCC.

Objective To evaluate the efficacy of chemoradiotherapy in patients with unresectable pancreatic cancer who were previously treated with PTCD.Methods From September 2005 to December 2012,47 unresectable pancreatic cancer patients with obstructive jaundice were enrolled in this study.They were divided into two groups.21 patients received after PTCD chemotherapy or radiation,or chemoradiotherapy.26 patients in support care group received only nutrition,analgesia and other related support treatment.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the groups were assessed for statistical significance with the log-rank test.Results The median overall survival time of patients after PTCD was 7.19 months.The median overall survival time of chemoradiation group was 9.07 months,which was higher than that of support care group (5.52 months),P=0.017.12 patients received single therapy (either chemo or radiation),and 9 patients received chemoradiotherapy.The median overall survival times were 8.31 months and 11.15 months,respectively (P =0.325).Conclusions Post PTCD chemoradiotherapy helps prolong the survival time in unresectable pancreatic cancer patients.

Objective To build three-dimensional (3-D) finite element models for local advancement skin flap, by which the post-operative local strain and local stress of skin were figured out to assist in the design of skin flap in clinic. Methods The biomechanical parameters of human forehead skin were obtained in vitro from biomechanical experiments. The 3-D finite element model of local advancement skin flap was set up by MSC Marc/Mentat 2005 (3-D finite element software). Six models were built with the same flap but different skin defects, to simulate post-operative local strain of skin and local stress of skin in different models. Results Post-operative local stress of skin increased with the skin flaps stretching, but the relationship between increase and stretching did not meet the linear rule. Skin flap was able to stretch to 40 % of its initial length in theory if we did not consider blood supply of it. When the skin flap stretched over 40 % of its initial length, the maximal stress could exceed the yield limit. Conclusion It is an effective and workable way to simulate local advancement skin flap using 3-Dfinite element model and biomechanical parameters of human skin. The stretch ratio of local advancement skin flap should be not over 40% for safety.
