Objective To understand the risk factors for postoperative pulmonary infection in patients undergoing spinal surgery,and put forward the intervention measures.Methods Patients who underwent spinal surgery in a hospital from May 2008 to June 2016 were analyzed retrospectively,they were divided into non-pulmonary infection group and pulmonary infection group according to whether they had postoperative pulmonary infection,clinical data of two groups were compared.Results A total of 612 patients who underwent spinal surgery were monitored,43 had postoperative pulmonary infection,incidence of postoperative pulmonary infection was 7.03％.Univariate analysis showed that 14 risk factors for pulmonary infection in patients after spinal surgery were as follows:length of hospital stay≥30 days,long-term smoking,chronic pulmonary disease,diabetes,number of surgical level≥2,general anesthesia,duration of operation≥4 hours,bleeding≥500mL,time of bed rest≥7 days,use of glucocorticoid,indwelling urinary catheter,mechanical ventilation,serum albumin＜30 g/L,blood glucose≥1 1mmol/L,and hemoglobin＜90 g/L(P＜0.05);while atomization inhalation was a protective factor(P＜0.05).Multivariate logistic regression analysis showed that 6 independent risk factors for pulmonary infection in patients after spinal surgery were as follows:length of hospital stay≥30 days,long-term smoking,chronic pulmonary disease,general anesthesia,time of bed rest≥7 days,and use of glucocorticoid(all P＜0.05),while atomization inhalation was a independent protective factor(P＜0.05).Conclusion Patients with pulmonary infection after spinal surgery is related to multiple factors,comprehensive and effective preventive measures should be taken according to the risk factors of postoperative pulmonary infection,so as to reduce the incidence of postoperative pulmonary infection in spinal surgery patients.

Objective To study the effects of rational emotive behavior therapy (REBT) in the rehabilitation of patients with spinal cord injury (SCI).MethodsA total of 300 SCI patients from six institutions were divided into a research group and a control group. Systematic rehabilitation was given to the patients of the control group, while systematic rehabilitation and REBT were given to the patients of the research group. All patients were followed up for 1 year. Psychological state, activities of daily living (ADL), and quality of life (QOL) were evaluated with a symptom check list (SCL-90), a modified version of the Barthel index (MBI) and the World Health Organization's quality of life assessment (WHOQOL-100).ResultsOne year after treatment, the improvement in QOL of patients in the research group was better, on average, than that in the control group. The differences were primarily in mental items. The ADL ability of patients in both groups improved, and any differences were not significant. The psychological state of patients in the research group had improved significantly 1 year after treatment, while the improvements in the control group were not significant on average, except in terms of interpersonal sensitivity.ConclusionREBT had little effect on the ADL ability of SCI patients, however, it improved their psychological state significantly, and thus improved their QOL.

Lactate dehydrogenase-C4 isozyme has been widely studied as the sperm-specific antigen in the research of the contraceptive vaccine. Developmental and testis-specific expression of the LDH-C gene requires mechanisms for activation in germ cells and repression in somatic cells. LDH-C promoter, several transcription factors and methylation of CpG dinucleotides have been proved of governing action on LDH-C gene transcription. The strategy is to induce antibodies in the female reproductive tract against LDH-C antigens at a sufficient level to block fertilization. Chemically modified LDH-C4 offers a potential application in the induction of infertility of homologous species in marked contrast to native LDH-C4. In addition, advances are being made in researches on the male contraceptive vaccine and synthetic peptide immunocontraceptive.

OBJECTIVETo study the effect of Tongluo Xingnao effervescent tablets on learning and memory capacity and expression of Na(+)-K(+)-ATPase in hippocampus of rats with chronic cerebral ischemia-induced learning and memory dysfunction model.

METHODThe 2-VO method was used to establish sd rat model learning and memory dysfunction induced by chronic cerebral ischemia. The 50 rats in the successfully established model were randomly divided into the model control group, the Dihydroergotoxine Mesylate tablets group (0.7 mg x kg(-1), Tongluo Xingnao effervescent tablets high dose (7.56 g x kg(-1)), middle dose (3.78 g x kg(-1)) and low dose (1.59 g x kg(-1)) groups and the sham operation group (n = 10) as the control group. The groups were orally given 10 ml x kg(-1) x d(-1) drugs for consecutively 90 days. On the 86th day, Morris water maze was adopted for them. On the 90th day, a leaning and memory capacity test was held. The brain tissues were fixed with 10% formaldehyde and observed for pathomorphism after routine slide preparation and staining. The expression of hippocampal Na(+)-K(+)-ATPase was detected with immunohistochemistry and image quantitative analysis.

RESULTCompared with the model group, all of Tongluo Xingnao effervescent tablets groups showed significant decrease in the escape latency at the 5th day in the Morris water maze, and notable increase in the frequency of the first quadrant dwell, the frequency passing the escape platform and the frequency entering effective area (p < 0.05). According to the pathomorphological detection, the control group showed a significantly higher pathological score than the sham operation group (p < 0.01), the middle dose group showed a significantly lower pathological score than the model group (p < 0.05). According to the immunohistochemistical detection, the model control group showed a remarkably lower mean OD value of Na(+)-K(+)-ATPase than the sham operation group (p < 0.05), high and middle dose groups showed a significantly higher mean od value than the model control group (p < 0.01).

CONCLUSIONTongluo Xingnao effervescent tablets can improve the learning and memory capacity, reduce pathological changes of hippocampal tissues of rats with chronic cerebral ischemia-induced learning and memory dysfunction model, and promote the expression of Na(+)-K(+)-ATPase in hippocampus.
