Objective:In vitro fertilization and embryo transplantation in patients with endometrial implantation window phase of natural killer cell ( uNK ) influence on the endometrial microvascular and uterine artery pulsatility index and embryo implantation.Methods:A retrospective analysis of our hospital from January 2009 to July 2013 the implementation of in vitro fertilization and embryo transfer(IVF-ET) clinical data of 37 patients,according to whether the success of pregnancy and at least 2 times for IVF-ET failure into success group(26 cases)and the failure group(11 cases),compared two groups of research object during the window of implantation in the uterus endometrial uNK cell marker CD56+, uterine artery pulsatility index, vascular endothelial marker F8 factor,alpha smooth muscle actin( alpha SMA) and myosin heavy chain( SMM) and the relationship between the expression of difference.Results:Success group based FSH 3.52±0.68(mU/ml),basal antral follicles of 9.44±2.53 compared with the failure group differences were not statistically significant(P>0.05).The successful group of uNK cells of 27.18±5.94(%),MVD 6.79±1.74 (%) ,αSMA 33.72 ±4.19 (%) , SMM 25.19 ±5.83 (%) were significantly higher than the expression rate of IVF-ET assisted reproductive failure group(P<0.05).The number of uNK cells,the proportion of endometrium during the window of implantation and MVD of 37 patients withαSMA and SMM coloring cell number proportion were positive correlation significantly( r=0.472,P=0.000<0.005),(r=0.426 ,P=0.000<0.005),(r=0.512,P=0.000<0.05).Success group during the window of implantation in the uterine artery PI=0.94±0.28,PI=0.87±0.29 failure group,differences between the two groups was not statistically significant(t=0.688,P=0.493>0.05).Conclusion:During the window of implantation in the endometrium of natural killer cells and endometrial angiogenesis was significantly associated with successful pregnancy, may have a certain relationship;uterine artery PI and pregnancy outcome successful has no obviously relationshhip.

Objective To evaluate the effectiveness of gamma knife and radioactive effect for glioma.Methods MR images of 106 cases with glioma treated by gamma knife were analysed based on classified.Results The effectiveness of gamma knife was the best for ependyoma and oligodendroglioma,the secondly for astocytoma (Ⅰ～Ⅱ) .The effectiveness for astrocytoma( Ⅲ～Ⅳ)was not well.The effective rate in 1 year after treament for astocytoma(Ⅰ～Ⅱ)was far higher than 2～3 years later.The 2nd year after treatment was the peak time for edema around tumor and the special radioactive contrast enhancement on MR.Conclusion Gamma knife is a effective therapy for glioma,especially for ependyoma,oligodendroglioma and astocytoma(Ⅰ～Ⅱ).The radioactive effect showed as edema and radioactive contrast enhancement on MR can become smaller or disappear 2 years later after treament.

Objective To investigate ectopic pregnancy from embryo transfer (ET)of in-vitro fertilization (IVF) cycle and intracytoplasmic sperm iujection (ICSI) cycle and frozen-thawed (FET) cycle.Methods From Jan.2005 to Dec.2010,a total of 9037 IVF-ET or ICSI-ET cycles and 4034 FET cycles were performed in our reproductive medicine center,Affiliated First Hospital of Zhengzhou University.The incidence of ectopic pregnancy rate was studied in fresh cycles IVF-ET (5998) and ICSI-ET (3039) cycles,and natural FET (2198) and hormone replacement (E-P) FET (1836) cycles.ResultsOf 4034 FET cycles,1090 clinical pregnancies and 26 ectopic pregnancies were observed,the incidence of ectopic pregnancy was 2.38％ (26/1090).Of 9037 fresh cycles,3602 cycles were clinical pregnancy,and 133 cycles were ectopic pregnancy,and the incidence of ectopic pregnancy was 3.69％ (133/3602).The ectopic pregnancy rate in FET cycles was lower than in fresh cycles significantly (P ＜0.05).Of 3039 fresh ICSI-ET cycles,the incidence of ectopic pregnancy was 2.62％ ( 34/1298 ) in 1298 clinical pregnancies.Of 5998 IVF-ET cycles,2304 clinical pregnancies were observed,the incidence of ectopic pregnancy was 4.30％ (99/2304).Ectopic pregnancy rate in the fresh ICSI-ET cycles was lower than that of IVF-ET group significantly (P ＜ 0.01 ).The ectopic pregnancy rate in the natural FET cycles was 1.46％ (8/547),which was significantly lower than 3.31％ ( 18/543 ) in E-P group ( P ＜ 0.05 ).ConclusionsThe incidence of ectopic pregnancy of FET cycles was significantly lower than that of fresh embryo transfer cycles.The application of exogenous sex hormones in assisted reproductive cycles might increase occurrence of ectopic pregnancy.

Objective To compare the advantages of three-dimensional(3D) and two-dimensional(2D) ultrasound in embryo transfer. Methods A total of 319 patients accepted embryo transfter were included in this study. 2D and 3D ultrasound were used to investigate the uterine cavity and transfer distance from the fundus (TDF),respectivly. They were divided into four groups according to TDF difference(D-TDF) between 2D and 3D ultrasound(group of DTDF<3mm,group of DTDF3～5mm,group of 6～9 mm,group of DTDF≥10 mm. Pregnancy outcomes among the four groups were compared. Results Of the 319 patients, 41 were observed to have abnormal uterine cavity. For 140 patients, the TDF measured by 2D ultrasound were different from that measured by 3D ultrasound. Clinical pregnancy rate and implantation rate were found lowest in group of TDF≥10 mm mm (7.7% vs 34.1%,38.1% ,40.0% and 3.6% vs 18.2% ,21.2% ,20.0%, P <0.05). Conclusions 2D ultrasound is limit and deficient for embryo transfer, especially for the visualization of uterine cavity and location of catheter tip, however, it may be better achieved with 3D ultrasound. It is helpful to use the 3D ultrasound to place the catheter tip accurately and improve the pregnancy rate of embryo transfer.

Objective To investigate the relationship between the resting heart rate (RHR) and target organ damage (TOD) in elderly patients with metabolic syndrome(MS). Methods 264 elderly patients with MS were divided into four groups according to the level of RHR: RHR1 group, RHR<65 beats/minute (bpm) (46 cases) ;RHR2 group, 65≤RHR<75 bpm (77 cases);RHR3 group, 75 bpm≤RHR<85 bpm (89 cases);RHR4 group, RHR≥85 bpm (52 cases).Electrocardiography, echocardiography, carotid uhrasonography, crcatinine clearance rate (Ccr) and quantitative assay of 24 hours' albuminuria were performed. Results (1) Compared with RHR1, RHR2 and RHR3 groups, RHR4 group showed higher levels of carotid intima-medial thickness (IMT), carotid arterial diameter (CAD), left ventricular mass index (LVMI) and albuminuria(P< 0.05 or P<0.01), and lower levels of left ventricular ejection fraction (LVEF) and Ccr (all P< 0.01). (2) The IMT, CAD, LVMI and albuminuria were positively correlated with RHR (r=0.33, 0.23, 0.61, 0.58, respectively, all P<0.01). However, the LVEF and Ccr were negatively correlated with RHR (r=-0.59, -0.51, all P<0.01). (3) Logistic multivariate analysis showed that RHR and pulse pressure (PP) had effects on myocardial hypertrophy, coronary heart disease, heart failure, cerebral stroke and renal dysfunction(P<0.05 or P<0.01). Except heart failure, PP played a more important role than RHR. Coneinsions RHR may be an independent risk factors for TOD in elderly patients with MS,and RHR regulation is important for the development of MS in the elderly.

Objective To establish a reliable approach for quantification of colony forming unit(CFU)of Mycobac-terium tuberculosis (M.tb)by measuring optical density(OD).Methods M.tb suspension H37Ra was prepared using low-power ultrasonic or glass bead beating methods,and was two-fold serially diluted,OD at 600nm (OD600)of each dilution ratio was measured respectively,OD600 and dilution curve were analyzed to determine the optimum approach for preparing bacterial suspension,linear range of OD600,as well as linear relationship between OD600 and CFU.Results OD600 was 0.1 -0.6,linear regression analysis of OD600 and dilution ratio within linear range revealed that correlation coefficient (R2 )of glass bead beating and low-power ultrasonic methods were 0.98 and 1 .00 respectively,both presented a good correlation,low-power ultrasonic method was better than glass bead beat-ing method,bacterial suspension dispersed more evenly.Linear regression analysis results of OD600 and CFU val-ues showed that the regression equation of glass bead beating method and low-power ultrasonic method were CFU=2.35×107 ×OD600+4.42×105 and CFU=3.26×107 ×OD600+6.89×105 respectively.Conclusion Low-power ultrasonic method is a good method for preparation of M.tb suspension,combined the measurement of OD600 value, it can be a reliable and rapid method for quantitative analysis of M.tb.

Objective To explore the diagnosis and treatment of five children with tuberculosis with arthritis as the initial manifestation. Methods The clinical features, laboratory tests and imaging manifestation of 5 children with joint tuberculosis were retrospectively analyzed. Results The course of disease was different. All the five patients were males (mean age 8.5 ±2.9 years old) and suffered from articular symptoms as initial feature. Four of them were diagnosed and treated as rheumatoid arthritis by other hospitals for up to three years, two patients have tuberculosis contact history, and another two patients were found with bone destruction, and one patient has pathologic fracture. Conclusions Tuberculosis is easily misdiagnosed as juvenile idiopathic arthritis , which deserves attention from a pediatric rheumatology physician.

BACKGROUND:Currently, modified laminoplasty with C7 spinous process and muscle attachment points reserved and C2, C7 decompressive laminectomy can reconcile both ful decompression and structure stability. With early isometric neck muscle exercise, it can enhance cervical dynamic and static force balance and maintain the stability of the cervical spine.
OBJECTIVE:To investigate the clinical effects of modified cervical laminoplasty with postoperative isometric neck muscle exercise on cervical spondylotic myelopathy patients.
METHODS:114 patients with cervical myelopathy were separately performed traditional cervical laminoplasty (control group), modified cervical laminoplasty (modified group), modified cervical laminoplasty, and neck muscle isometric exercise (combined group). Fol ow-up was conducted for 24 months.
RESULTS AND CONCLUSION:(1) Cervical Japanese Orthopaedic Association score, cervical Neck Disabilitv Index scores and the incidence of axial symptoms:There was no significant difference in the Japanese Orthopaedic Association score of three groups at 6, 12 and 24 months after surgery. At 6, 12 and 24 months after surgery, Neck Disability Index scores and constituent ratio of axial symptoms were better in the modified group than the other groups (P<0.05). (2) Results show that modified cervical laminoplasty with isometric neck muscle exercise can get better clinical results in the treatment of cervical myelopathy.
