ABSTRACT
Objective To investigate the effect of different delivery methods on the levator ani muscle of the pelvic floor by transperineal three-dimensional ultrasound and TUI imaging. Methods 200 cases of pregnant women from August2014 to August 2016 in our hospital were divided into selective cesarean section group (n = 85) and vaginal delivery group (n= 115). The vaginal group, according to the intraoperative lateral segmentation, was further divided into vaginal lateral incision group (n = 65) and vaginal delivery without lateral incision group (n = 50). At the same time, select 80 cases of nulliparous women (volunteers) as control group, relevant indicators by three-dimensional imaging and TUI imaging technique. Results The vaginal delivery without lateral incision group, lateral incision group vaginal delivery and cesarean section group levator hiatus diameter, anteroposterior diameter, perimeter and area were significantly higher than the control group(P＜0.05), and vaginal delivery side cut was significantly higher than the other three groups (P＜0.05), vaginal delivery in two sub-group and cesarean section group of levator ani muscle thickness were significantly lower than the control group(P＜0.05), vaginal delivery in two sub groups were significantly lower than that in the cesarean section group (P＜0. 05); vaginal delivery group of levator ani muscle injury rate was significantly higher than that in the cesarean section group (P＜0. 05); There was no significant difference in the rate of levator ani muscle injury in vaginal delivery group (P＞0.05). Conclusion Compared with cesarean section, vaginal delivery is more obvious in changing the morphology and integrity of levator ani muscle, and vaginal delivery is more obvious than that of vaginal incision.
ABSTRACT
Objective To investigate the clinical value of HLA-B27 testing in diagnosis of ankylosing spondylitis (AS) by flow cytometry. Methods The peripheral blood HLA-B27 was detected by flow cytometry in 75 diagnosed AS patients (AS group), 95 suspected AS patients (non-AS group) and 45 health people (control group). Results The fluorescence intensity and the positive rates of HLA-B27 in AS group were significantly higher than those in non-AS group and control group: 158.0 ±24.0 vs. 94.8 ±30.5 and 89.1 ±18.9, 93.33% (70/75) vs. 5.26% (5/95) and 4.44% (2/45), and there were statistical differences (P<0.05). The sensitivity of HLA-B27 in diagnosis of AS was 93.3% (70/75), the specificity was 94.7%(90/95), while the accuracy was 94.1%(160/170). Conclusions There is a high correlation between AS and HLA-B27. The flow cytometry assay of HLA-B27 plays an important role in the early diagnosis and differential diagnosis of AS.
ABSTRACT
Purpose The aim is to investigate the effects of BSP on immunological function in normal and immunosuppressed mices.Methods Thymus and spleen indexes, peripheral blood WBC number,the lymphocyte proliferation response, IL-2 production and serum and splenocyte hemolysin contents were measured after intraperitoneal injection of BSP in normal and immunosuppressed mices.Results (1)BSP 100 mg/（kg*d）×10d significantly increased the thymus and spleen indexes and peripheral blood WBC number in immunosuppressed mice.The thymus and spleen indexes in normal mice was also increased. In addition,BSP markedly improved T,B lymphocyte proliferation responses and IL-2 production in normal and immunosupressed mices.(2) BSP improved the serum and splenocyte hemolysin contents in normal and immunosuppressed mice. Conclusion It was suggested that BSP was a kind of immunomodulator, and could improve the immunological function of normal and immunosuppressed mices.
ABSTRACT
OBJECTIVE:To probe into the effects of carrying out"Prescription Set"self-help service in cooperative medical care clinic service in countryside in lessening the economical burden of peasants patients and enabling more people benefited from the basic health care.METHODS:Targeting at the common diseases in clinic service of the health center,for each of which at least3kinds of treatment plans prescription in different prices were worked out,to make the peasants patients choose the prescription freely.RESULTS&CONCLUSION:The outpatient number has increased significantly while medical expenses on prescriptions of outpatients decreased significantly in the primary level hospitals and community clinics through the practice of"Prescription Set"self-help service.
ABSTRACT
The phenotyping of erythrocyte esterase D of 221 Chinese random donors,Han nationalities in Shenyang,China,was performed by the agarose gel electrophoresis.Gene frequencies were:E_SD~1=0.629,E_SD~2= 0.371.There is no significant difference of gene frequencies of Han nationalities between Shenyang and Beijing.The minimal amount meeted the requirment for detection of E_S D were 1?l of fresh hemolysate or 1?l hemolysate.The E_S D can be detected from the hemolysates kept in 37℃ for 7～8days as well as from 1?l hemolysate bloodstain kept for 2 weeks and 5?l hemolysate bloodstain kept for 3 weeks.
ABSTRACT
Objective: To investigate the effects of BSP on lymphocyte function and cytokines production in normal and immunosuppressed mice.Methods: The lymphocyte proliferation response, T lymphocyte subpopulations and IL 2 production were measured after intraperitoneal injection of BSP in normal and immunosuppressed mice, and the activity of IL 1 and TNF secreted by mouse peritoneal macrophages were detected after BSP supplementation in vitro.Results: (1)BSP〔(100 mg/(kg?d)?10 d)〕markedly improved T,B lymphocyte proliferation responses and IL 2 production in normal and immunosuppressed mice, and significantly increased the number of L 3T + 4 cells in thymus and spleen of immunosuppressed mice, and the ratio of L 3T + 4/Lyt 2 + cells was also increased.(2)BSP distinctly enhanced the activity of IL 1 and TNF production by mouse peritoneal macrophages in vitro.Conclusion: BSP can improve the immunological function of normal and immunosuppressed mice.
ABSTRACT
Neurohypophyses of six adult rats were observed under electron microscope toinvestigate the morphological features of pituicytes and their possible functionalsignificance.The results of morphological observation showed that the pituicytesmay be divided into 4 types,the two of which,astral pituicytes and ependymalpituicytes,obviously resemble to the neurogliocytes of central nervous system intheir morphological features.The third,dark pituicytes,was rich in mitochondria.Little was known about secretory pituicytes other than their presumable secretoryfunction suggested by the secretory granules present in their cytoplasm.The interstitial cisternae were the sites where the neurosecretory activities carriedon.The dilations of nerve fiber around the interstitial cisternae were rich in vesi-cles.It was substantiated that the pituicytes can participate in supporting andnourishing the nerve fibers,removing cell debris and may also serve a function oftransferring excitation,because of the presence of gap junction between pituicytes andynapselike contact between pituicyte and the nerve fiber.
