BACKGROUND:Fragile bone in senile osteoporosis patients easily weakened pedicle screw fixation capacity. Therefore, bone cement leakage and screw removal cannot be solved during pedicle screw repair in osteoporotic patients with degenerative lumbar spine. OBJECTIVE:To investigate the biomechanical properties of novel pourable pedicle screws and bone cement application effect in osteoporotic patients with degenerative lumbar spine. METHODS:Six lumbar specimens (T11-L5) at the mean age of (72.9±4.2) years were selected, total y 42 vertebrae. The average bone density was 0.696 g/cm2. Any side of al vertebrae was inserted with pourable pedicle screws. 2 mL of bone cement was perfused under the X-ray fluoroscopy with cement push rod and fil ing cylinder. The same number of conventional screws was inserted into the opposite side of the samples. Three-point bending test was performed in two kinds of screws. The maximum vertebral axial pul out force test and the maximum spin torque test were conducted in vertebra to observe the destruction of the vertebral body and implanted effect. RESULTS AND CONCLUSION:(1) The ultimate strength and yield load of novel pourable cement pedicle screws were significantly more than conventional screws (P<0.05). Ultimate displacement and yield displacement were significantly less in novel pourable cement pedicle screws than in conventional screws (P<0.05). (2) The maximum vertebral axial pul out force and the maximum spin torque were significantly higher in novel pourable pedicle screws than in conventional screws (P<0.05). (3) In summary, novel pourable cement pedicle screw is simple to operate, can effectively control bone cement penetration, and improve screw stability in osteoporotic vertebrae. Moreover, after treatment, the removal of screws is convenient, cannot evidently destroy vertebral body or screw channel, and promote early recovery.

Objective To discuss the risk factors and nursing intervention of multidrug-resistant organism (MDRO) infection in patients of traditional Chinese medicine hospital (TCM). Methods By investigating the patients admitted to Beijing Xuan Wu Hospital of Traditional Chinese medicine from June 2015 to June 2016, 756 patients of them who were confirmed with clinical diagnosis of infection and pathogen detection with positive, which were divided into MDRO group including 97cases and non-MDRO group including 659 cases, then the pathogens of MRDO infection species and distributionwere counted, and analyzed risk factors for infection. Results A total of 756 cases were detected positive strains 816 strains, including 611 strains of monitoring target strains, 116 strains of MRDO. The top three were methicillin-resistant staphylococcus aurous 30.17%(35/116), Pseudomonas aeruginosa 18.97% (22/116) and Klebsiella pneumonia 18.10% (21/116). Single factor analysis results showed that the patients' age, hospitalization days, the history of other hospital admission, invasive procedure, basic chronic disease (diabetes, cerebrovascular disease, lung disease) and combined use of antibiotics were MDRO infection risk factors (χ2=9.470-198.609, P < 0.01); multivariate Logistic regression analysis showed that the independent risk factors of MDRO infection were the history of other hospital admission (OR=2.085, 95%CI1.040-4.179), invasive procedure (OR=3.063,95% CI1.526- 6.150), diabetes (OR=2.037,95% CI1.070- 3.877), cerebrovascular disease (OR=4.349,95%CI 2.035-9.293)and combined use of antibiotics (OR=18.723,95% CI9.202-38.094). Conclusions Patients of TCM have many characteristics, such as with more basic diseases, longer length of stay, elder and so on. So we should be alert to the risk of MDRO infection and take nursing interventions to prevent and strengthen the isolation prevention.

Objective To explore the effect of TNF-α in intracellular Ca~(2+)-overload associated myocardial injury. Methods Thirty Wistar rats were randomly divided into three groups:control group,Ca~(2+)+-paradox group,and pentoxifylline treatment group. The intracellular Ca~(2+)-overload rat model was established by pre-filling the rats with Langendorff for 20 minutes,isolated rat hearts subjected to Ca~(2+)-depletion for 5 minutes and Ca~(2+)-repletion for 30 minites(Ca~(2+)-paradox). Changes in hemodynamics indexes were monitored continuously. TNF-α in cardiac tissues was tested by ELISA method,and nuclear factor-κB(NF-κB)in cardiac tissues was detected with Western blot. Results Dramatic depression in left ventricle contraction function was found in the Ca~(2+)-paradox hearts:significant decrease in left ventricular diastolic pressure(LVDP),markedly elevated left ventricular end diastolic pressure(LVEDP),decreased dP/dt ratio,increased TNF-α content,decreased cytosolic/homogenate NF-κB ratio. All these changes in Ca~(2+)-paradox group were significantly attenuated upon the treatment with 100 μmol/L pentoxifylline. Conclusions Activation of NF-κB and increased production of TNF-α may play important roles in cardiac injury associated with intracellular Ca~(2+)-overload.

Objective To retrospectively overview the malaria death cases reported in Henan Province and analyze the cause of death. Methods The data including basic information,epidemiological survey and medical records of malaria death cases in Henan Province from 2010 to 2015 were collected and analyzed. Results In the six years,a total of 14 malaria pa?tients were dead. All the death patients were adult males and imported from Africa. They had definite histories of living in malaria?epidemic areas and the symptoms of fever. Twelve patients were diagnosed as malaria after at least twice diagnoses. The average time from symptom appearing to correct diagnosis was 6.5 d. The causes of deaths were misdiagnosis and delayed treatment. Con?clusions The major reasons of malaria death cases in Henan Province are the failure of correct diagnosis and prompt treatment. Health education of malaria prevention and diagnosis and treatment training of malaria should be strengthened in order to im?prove the public awareness and the diagnosis ability of clinical doctors for malaria,which can prevent the death of imported ma?laria cases.

Objective To identify the genetic variants of WNK4(with no K=lysine kinase)gene in Kazak population in Xinjiang province,to determine whether the WNK4 gene intron 10 polymorphism iS associated with essential hypertension(EH)and to investigate the distribution of genotype and allele frequencies of WNK4 gene. Methods One hundred and ninety-one patients with EH and 173 normal blood pressure controls were included in the study to assess the contribution of polymorphism of WNK4.Direct DNA sequencing was performed to identify the single nucleotide polymorphism(SNP)in 16 SUbjects with EH and 16 subjects of normotension(NT).Then the polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method was used for the detection of WNK4 genotype. Results One SNP located in the 10 intron of WNK4 (1156666 base of chromosome 17)was found in the Kazak population.The genotypes of the variants were found to be in Hardy-Weinberg equilibrium.GG,AG,AA genotypes were 88.0%,11.0 oA,1.0%in the EH group and 91.9%,8.1%,0%in the NT group,respectively.The frequencies of genotype and allele in EH group were not significantly different from NT group in Kazak population.Conclusions It suggests that the intron 10 polymorphism of WNK4 gene might be not associated with hypertension in Kazak population.
