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.

· AIM: To evaluate the combined effect of rapamycin ophthalmic solution and cyclosporin A ophthalmic solution on allogeneic transplantation in a rat model.rats were used as donors. The animals were randomly assigned to 4 groups. Group A: control (ophthalmic solution solvent 100μ L); group B: 2g/L rapamycin ophthalmic solution 100μ L; group C: 10g/L cyclosporin A ophthalmic solution 100μ L; group D: 2g/L rapamycin ophthalmic solution 50μ L and 10g/L cyclosporin A ophthalmic solution 50μ L, 4 times every day. The treatment was started on 2d after operation, and the animals were administered until rejection. The grafts were inspected by slit-lamp microscope and the corneal survival time was recorded. The pathologic changes were measured by light microscope.significantly prolonged compared with the control group (P ＜ 0.01). However, the combined therapy (group D) was significantly superior compared with group B and C (P＜0.05, P＜ 0.01). The histopathological findings showed that the inflammation cells, neovascularity in each treated group were significantly fewer than that in control group at 14d after operation.a double drug regimen with rapamycin ophthalmic solution and cyclosporin A ophthalmic solution for the control of acute corneal allograft rejection. It indicats that the combined therapy produced synergistic effect.

Objective To observe the effect of trichostatina to induce mesenchymal stem cells(MSCs) differentiating into cardiomyocyte cells and to explore the potential interference approaches.Methods MSCs were incubated with different concentrations of TSA and different time,then to detecte the histone deacetylase(HDAC) activity;the differentiation of MSCs was observed by phase-contrast mictmcopy;fluorescence immunohistochemistry assessed cardiac troponin T and RT-PCR detected the expression of Nkx-2.5,GATA-4 genes.Results HDAC activity was the lowest when incubated with 300 nmol/L TSA for 24 hours,expression of cTnT of the cells was enhanced after incubation with TSA.The expression of Nkx-2.5,GATA-4 genes was enhanced before interference.ConclusionTSA can promote MSCs to differentiate into cardiomyocyte cells in vitro in an optimized condition.

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 investigate the efficacy and safety of amisulpride and clozapine in schizophrenia patients with predominantly negative symptoms.Methods Totally 166 cases of schizophrenia patients with predominantly negative symptoms from May 2013 to May 2016 in The Sixth People's Hospital of Hebei were divided into observation group and control group,83 cases in each group.Patients in the observation group were treated with amisulpride,and control group were treated with clozapine.The clinical effect,SANS scores,and occurring rate of abnormal electrocardiogram were compared.Results The clinical effect,emotional insipid (blunting),and attention dysfunction scores from SANS of observation group were significantly better than those of control group on week 4,8,and 12,respectively (P ＜ 0.05);The occurring rate of abnormal electrocardiogram in observation group was significantly lower than that of control group on week 12 (P ＜ 0.05).Conclusion Compared with clozapine,amisulprid has better efficacy and safety in schizophrenia patients with predominantly negative symptoms,and can effectively improve of symptom of insipid (blunting) and attention dysfunction.

Objective To assess the value of magnetic source imaging (MSI) in localizing the linguistic center of auditory function of epileptic patients before operation. Methods Epileptic focus and the linguistic center of auditory function in 24 patients were localized with MSI before operation. And the relationship between epileptic focus and auditory language area was observed. Results The linguistic center of auditory function was localized in left temporal lobe in 14 patients, in right temporal lobe in 5 patients and in bilaterial temporal lobe in 5 patients. Epileptic focus was localized in left temporal lobe in 14 patients, in left temporal lobe and left parietal lobe in 1 patient, in right temporal lobe in 4 patients, in right temporal lobe and parietal lobe in 1 patient, in left frontal lobe and left temporal lobe in 1 patient, in right frontal lobe, right temporal lobe and parietal lobe in 1 patient, and in bilaterial temporal lobe in 2 patients. Epileptic focus was superimposed with the linguistic center of auditory function in 10 patients, while was not superimposed with the linguistic center of auditory function in 10 patients. The epileptic focus was localized in front of the linguistic center of auditory function in 3 patients, in behind of the linguistic center of auditory function in 1 patient. The lesion of the patient suffered from dysembryoplastic neuroepithelial tumor was not excised completely because the epileptic focus was superimposed with the linguistic center of auditory function, and the patient appeared language functional disturbance after operation in short period, remaining auditory hallucination occasionally after operation. Conclusion Epileptic focus and the linguistic center of auditory function can be localized accurately and the relationship between them can be observed clearly with MSI. MSI is useful to reduce the occurrence of language disturbance after operation.
