Objective To explore the nursing intervention on the pregnant women with syphilis during pregnancy so as to reduce the harm to maternal and baby.Methods Many information such as age,occupation,dwelling environment,marriage and sexual life,curing during pregnancy,pregnant and perinatal infant outcome from medical records were reviewed. Gestational syphilis women of 847 cases were randomly divided into nursing intervention group with 427 cases and control group with 420 cases.Nursing intervention group received one-by-one psychological care and health education,got cooperation from families,and received routine blood test and cure cooperation,while control group only received routine blood test and curing cooperation.Patients were followed up for seven days.Results The rate of adherence to treatment in nursing intervention group was 98.1％ which was significantly higher than 61.7％ in control group ( x2 =176.2,P ＜ 0.01 ),and the rate of accepting standard treatment between early and late pregnancy,middle and late pregnancy were significantly higher than that in control group ( x2 =17.8,P ＜ 0.01 ).The week was shorter for receiving nursing intervention and the patients' compliance was better ( P ＜ 0.01 ). Only 23 syphilis infection babies in the nursing intervention group were born,but 149 babies in control group were infected by syphilis,and the difference was significantly different( x2 =123.2,P ＜ 0.01 ).Conclusions Nursing intervention can effectively increase the compliance of pregnant women with syphilis and improve the outcome of pregnancy and perinatal infant.

Objective To investigate the risk factors for postoperative arytenoid dislocation.
Methods From September 2003 to August 2013, the records of 16 patients with a history of postoperative arytenoid dislocation were reviewed. Patients matched in terms of date and type of procedures were chosen as the controls (n=16). Recorded data for all patients were demographics, smoking status, alcoholic status, preoperative physical status, airway evaluation, intubation procedures, preoperative laboratory test results, anesthetic consumption and intensive care unit stay. For arytenoid dislocation cases, we further analyzed the incidences of the left and right arytenoid dislocation, and the outcomes of surgical repair and conservative treatment. Categorical variables were presented as frequencies and percentages, and were compared using the chi-squared test. Continuous variables were expressed as means±SD and compared using the Student’s unpaired t-test. To determine the predictors of arytenoid dislocation, a logistic regression model was used for multivariate analysis.
Results Sixteen patients with postoperative arytenoid dislocation were enrolled, with a median age of 52 years. Most postoperative arytenoid dislocation patients (15/16, 93.75%) received surgical repair, except one patient who recovered after conservative treatment. None of the postoperative arytenoid dislocation patients were smokers. Red blood cell (P=0.044) and hemoglobin (P=0.031) levels were significantly lower among arytenoid dislocation cases compared with the controls.
Conclusions Non-smoking and anemic patients may be susceptible to postoperative arytenoid dislocation. However, neither of them was independent risk factor for postoperative arytenoid dislocation.

Objective To investigate the clinical and mammographic features of plasma cell mastitis.Methods Twenty-five patients(28 lesions)with histologically confirmed plasma cell mastitis, aged from 26 to 70 years(mean age 41 years),were examined with X-ray mammography.The clinical manifestations and imaging features were retrospectively reviewed.Results No case was in lactation.The painful irregular masses,ranged from 1.3 to 8cm in size,were found in 22 patients,while 3 patients with acute episode.Recurrent episodes of breast masses were noted in 4 patients.Based on the mammographic appearances,the plasma cell mastitis were classified as the following four types:inflammation-like type (2/28),ductal ectasia type(3/28),focal infiltration type(10/28)and nodular type(13/28).The valuable radiogyaphic signs:(1)An asymmetrically increased density along the lactiferous duct with a flame-like appearance,inhomogeneous low density tubular structures and scattered stick-shape calcifications.(2) Architectural distortion and oil cysts formation in adjacent area,(3)Subareolar ductal ectasia.Conclusions The clinical and mammographic characteristics of plasma cell mastitis are critical to avoiding unnecessary surgery.Histopathological result is needed for the diagnosis in patients highly suspected of malignancy.

The purpose of this study was to evaluate the in vivo viability of human platelets cryopreserved at -80 degrees C by using SCID mouse model and flow cytometry. The fresh human platelets were frozen with 5% DMSO at -80 degrees C for 10 days, thawed, and centrifuged for concentration. A 100 ml aliquot of concentrated platelets was injected into the SCID mouse tail vein by using a 1 ml insulin-syringe fitted with a 29-gauge ultra-fine needle. The whole blood was collected into heparinized capillary tube at 0.5, 2, 4, 6, 12, and 24 hours after infusion via a tail vein and was labelled with CD61-PE. Then the human platelets in mouse whole blood were detected by flow cytometry. The 30 minute time point was used as 100% to calculate the survival time of human platelets. The results showed that the survival time of cryopreserved human platelets were more significantly decreased than that of fresh platelets in SCID mice. Survival rates at 4 hours after transfusion of fresh platelets and cryopreserved platelets in SCID mice were 79.5% +/- 9.1% (n = 8) and 40.6% +/- 6.6% (n = 8) respectively, and a T(1/2) estimated were 7 hours for fresh platelets, but 2.5 hours for the cryopreserved. In conclusion, platelets survival time in SCID mice was shortened after frozen with DMSO at -80 degrees C.

OBJECTIVETo investigate the elastic limit and relevant enclasp force of the non-precious metal casting clasp.

METHODSCasting clasp samples of five cobalt-chromium alloys and one 18 - 8 nickel-chromium alloy were made from prefabricated clasp wax by invesing, casting, sandblasting, and ultrasonic cleaning. The process of casting clasp samples deflected by loading and returned by unloading was tested and electric signals were collected by an omnipotent material machine. The analog electric signal was converted to digital signal by an analog to digital converter and stored in a computer. The elastic limit and the relevant enclasp force were analyzed using a relative software.

RESULTSThe elastic limit and the relevant enclasp force of the casting clasp made from the 18 - 8 nickel-chromium alloy were smallest and those of the clasps made from the cobalt-chromium alloys in various brands were different. The range of the elastic limit of the cobalt-chromium alloy casting clasp with the length of 5.0 mm in undercut was 0.28 mm-0.33 mm and the relevant enclasp force was 14.42 g-19.28 g.

CONCLUSIONSIn clinic, we should select the suitable undercut deepness wherein the cobalt-chromium alloy casting clasps, according to different brands of the casting alloy, undercut length, undercut slope, and the clasp thickness.

To study the effect of interleukin-15 (IL-15) on the proliferation, differentiation and apoptosis of MDS CD34(+) cells, CD34(+) cells of high enrichment were separated by MACS system, and cultured in liquid media with different concentration of IL-15 in treated group and without IL-15 in the control group. Apoptosis of hematopoietic precursors was assayed by propidium iodine staining and cell by FCM, and the other MDS CD34(+) cells were stained by cytochemical staining after culture. The results showed that after culture with IL-15 the proliferation and differentiation of MDS CD34(+) cells were obviously promoted. It was found the every lineage of mature cells developed, the expressions of cell surface antigens CD71, CD33 and CD19 all increased in the MDS CD34(+) cell treated with IL-15. It is suggested that IL-15 stimulates the proliferation and differentiation of MDS CD34(+) cells, and partly shows anti-apoptosis effects which may be applicable to the therapy MDS.

OBJECTIVEThe expression of C/EBPalpha protein and mRNA during automatically activation process in primary cultures of HSCs were observed in order to explore its possible association with the proliferation and activation of HSCs.

METHODSImmunocytochemistry, Western blot and RT-PCR were used to evaluated the expression of C/EBPalpha protein and mRNA; as well as the expression of alpha-SMA, Desmin, MMP2, type I procollagen (alpha1). The eukaryotic vector harboring the full length cDNA of C/EBPalpha was transfected into activated HSC, then immunocytochemistry was applied to confirm the transfection and evaluate the effect of transfection on the proliferation of HSC by calculating the PCNA-positive cells. The morphological changes of HSC were observed by use of phase-contrast microscope.

RESULTSConstitutive expression of mRNA and protein of C/EBPalpha were detected in primarily cultured HSCs, and the protein was seen in both nuclei and cytoplasm with the latter being dominant. Their expression levels reached highest at day 2 of the culture, then decreased gradually when continually cultured to the day 4, 7, 10, on the other hand, the expression of alpha-SMA, MMP2 and ColI(alpha1) increased steadily. Transient transfection was verified by the fact that much more and stronger C/EBPalpha stain was observed in transfected HSCs than in void-vector transfected cells. In C/EBPalpha gene transfected HSCs, the number of PCNA-positive cells dramatically decreased compared with the void-vector transfected cells 24h after transfection. In addition, the C/EBPalpha gene transfected HSCs died 36 h after transfection, a few surviving cells became longer and thinner in morphology, however the void-vector transfected cells almost all remained alive.

CONCLUSIONSC/EBPalpha was likely involved in the HSCs activation, and over-expressed C/EBPalpha by transfection had inhibitory influence on the proliferation of cultured rat HSCs.
