Objective To compare effects of both ends of the injection cesarean section anesthesia differ-ences.Methods ASAⅠ-Ⅱgrade cesarean section 226 cases were selected and randomly divided into the observa-tion group and control group on the basis of number characterization.Observation group:After the success of epidural puncture needle oblique injection of 1.7% for the end of lidocaine carbonate 5mL,then needle bevel steering head end 3-5min without observing all spinal abnormalities such as re-injection of 5mL of 1.7% lidocaine carbonate,fol-lowed by epidural catheter inserted,modified supine position to continue after injection of 1.7% lidocaine carbonate 5mL;Control group:after the success of epidural catheter tip administered by traditional teaching methods.Two groups of maternal range block plane , intraoperative pain intensity and time of delivery of the fetus were recorded .intraoperative changes in vital signs and Apgar score after the fetus were observed.Results The block wide range for anesthesia of the observation group[(14.43 ±1.21)points]were significantly higher than that of the control group,and intraopera-tive pain was (1.61 ±0.92)points,fetal childbirth lengthwas (1.8 ±0.6)minutes,which were better than those in the control group(t=12.76,13.07,12.86,all P<0.05);The MAP,HR,R,SpO2 between the two groups showed no significant differences(F=4.32,2.73,3.54,3.06,all P<0.05);Intraoperative vital signs and Apgar score was con-firmed no difference between the two groups(all P>0.05).Conclusion Both ends of the epidural injection for ce-sarean section is better than the traditional mode of administration of anesthesia.

Objective: To study iron deficiency (ID) of newborns caused by ID in pregnant women and the effect of iron supplementation. [WT5FZ]Methods: [WT5BZ]Forty four pregnant women were divided into control and iron groups randomly and began to take placebo or iron during median phase of pregnancy. Several indices including serum iron (SI), total iron binding capacity (TIBC), transferrin saturation (TS) and serum ferritin (SF) were measured. Hemoglobin concentrations were obtained from clinical records. [WT5FZ]Results: [WT5BZ]The Hb,SI,TS and SF of newborns in control group were lower than those of newborns in iron group. The incidence of anemia and insufficiency of iron store of newborns in control group were 80% and 54.5% respectively, which were higher than those of newborns in iron group. Except SI of newborns and SF of pregnant women, the SI, TS and SF of newborns were positively related to those of pregnant mothers. Fewer women in iron group suffering from iron deficiency anemia by the end of pregnancy compared to the control were noted. From median phase to the end of pregnancy the Hb, SI, TS and SF of pregnant women in control group remained constant or lower, while the Hb, SI and TS of the pregnant women in iron group got higher and their SF didnt decrease progressively. [WT5FZ]Conclusion: [WT5BZ]The relationship between the nutritional status of iron of pregnant women and newborns is closely related. ID of pregnant woman can lead to the ID of her newborn. Iron supplementation can reduce ID of pregnant women and newborns.

Objective To investigate the changes in femoral gene expression profiles in C57BL/6 mice fed high-fat diet (HFD) via clustering analysis of DNA microarray.Method Sixteen male C57BL/6 mice (4w old) were randomly assigned to two groups,8 in each,after 4-d ordinary diet for adaptation.The control group was fed with an ordinary diet,and the HFD group with HFD(19.5% lard).All mice were sacrificed at the end of 12w and the femoral gene expression was detected by oligonucleotide microarray analysis with Affymetrix Gene Chip Mouse U430A.DAVID,an online tool,was used for clustering analysis on femoral gene expression.Results Longtime administration of HFD caused femoral gene expressed differences related to cation ion channel,transcription regulation and signal transduction,bone mineralization,phosphate metabolic process regulation,and collagen synthesis.Conclusion Longtime intake of HFD will change the expression of numerous bone metabolism-related genes in bone of mice,and then inhibit bone formation.

Objective To investigate the adhesion mechanism of Lactobacillus acidophilus FN001外to Peyer's patches. Methods Adhesion of L. acidophilus FN001 to mice Peyer's patches was studied in vitro using a fluorescent quantization method. The nature of adhesion mediator was studied by the effects of physical, chemical and enzymatic pre-treatments of the bacteria on their adhesion and effect of sugars on in- hibition of adhesion. The presence of lectin-like proteins in the cell surface was determined by hemagglutina- tion. Effect of L. acidophilus FN001 on inhibition of adhesion of pathogens to Peyer's patches was also stud- ied. Results The adhesion of L. acidophilus FN001 was strongly inhibited in the presence of D-mannose and methyl-ct-D-mannoside. Pretreatment of L. acidophilus FN001 with pepsin and trypsin decreased the ad- hesive capacity indicating that cell surface proteins are involved in adhesion to Peyer's patches. L. acidophi- lus FN001 could agglutinate rabbit red cell in mannose specific manner and protease pretreatment could de-crease hemagglutinin, suggesting that L. acidophilus FN001 has mannose specific lectin (s). In adherence inhibition assay, L. acidophilus NF001 could significantly inhibit adhesion of E. coli ATCC25922 to Peyer's patches when L. acidophilus NF001 were applied to Peyer's patches first or at the same time with pathogen. Conclusion It was concluded that a mannose-specific protein mediated adhesion of L. acidophilus FN001 to the Peyer's patches, and L. acidophilus FN001 could inhibit adhesion of pathogen with similar lectins speci- ficity to Peyer's patches.

Objective:To evaluate the value of CT angiography (CTA) for vertebral artery (VA) injury in the transverse foramen region of cervical vertebra.Methods:The clinical and CTA imaging data of 56 patients with cervical spine trauma in People's Hospital of Yuxi City from January 2016 to December 2019 were retrospectively analyzed. To observe the VA were or not injuried and their degrees, and the relationship between fracture in transverse foramen region and injured of the VA by applying post processing techniques such as volume reconstruction (VR), image fusion, curved planar reconstruction (CPR), multi-planar reconstruction (MPR), vascular analysis and so on.Results:There were 35 cases in the positive group of transverse perforation stenosis among the 56 patients, and 21 cases in the negative group. There were 19 cases injuried the VA in the positive group of stenosis, but just 5 cases′VA were injuried in the negative group of stenosis, with statistically significant differences ( P<0.05). The risk of VA injuried caused by different degrees of transverse perforation stenosis in the positive stenosis group was statistically significant ( P<0.05). The VA damaged distribution were: 3 cases in V1 segment, 16 cases in V2 segment, 5 cases in V3 segment. The degree of luminal stenosis were: 9 cases of mild stenosi, 7 cases of moderate stenosis, 5 cases of severe stenosis, and 3 cases of luminal occlusion. Conclusions:The CTA of VA can clearly show its anatomical route, degree of injury, range and its adjacent relationship with the fracture end of the transverse foramina of cervical vertebra, which can provide evidences of objective and reliable imaging for spinal surgeons to assess their conditions and select the treatment plans.

OBJECTIVE To find the differences in QOL between patients treated with total laryngectomy with voice rehabilitation or without voice rehabilitation and subtotal laryngectomy, to analysis the factors affecting QOL of patients after laryngectomy by HNQOL. METHODS With HNQOL,a survey was conducted in patients treated with total laryngectomy (30cases) with voice rehabilitation, 30 cases without voice rehabilitation, and 30 cases treated with subtotal laryngectomy for laryngeal cancer. We discuss changes of QOL with time went by,and analysis the factors affecting QOL of patients after laryngectomy. RESULTS There is no difference between patients treated with total laryngectomy with .voice rehabilitation and the one treated with subtotal laryngectomy in their quality of life, however, there is difference between patients treated with total laryngectomy without voice rehabilitation and the one treated with subtotal laryngectomy. CONCLUSION Through voice rehabilitation ,we could advance quality of life of the patients treated with total laryngectomy. Through the integration of psychological, clinical and social intervention, the quality of life of patients may have an overall improvement.
