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 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.

An analysis of the existing incentives mechanism of performance appraisal for community health service centers, and insight into the challenges for linking the post performance appraisal in community health service centers with incentive measures. It is pointed out the administrators should take a variety of measures including material incentive, target incentive, knowledge incentive, and emotional incentive among others. In addition, such measures should be used sophistically, flexibly and reasonably, while timing of incentives should meet the human resource needs of the institution, notably a combination of positive incentive with negative ones,, mostly the former incentive.

A brief description of performance appraisal as used in the healthcare sector, and an analysis of problems existing in performance appraisal for posts in community heahhcare organizations in the country. The paper proposes a job-analysis based performance appraisal for such posts, featuring the appraisal model of "performance + skills + attitude+ work intensity". On the basis of work analysis, a job description should be worked out for such healthcare workers as doctors, nurses and prevention workers in community healthcare organizations, aided by a targeted job-based performance appraisal system. These efforts can effectively enhance the job performance in such organizations, catering to the healthcare needs of community residents.

Objective To investigate the effect of preoperative percutaneous dilatational trache-otomy (PDT)in oral and maxillofacial surgery anesthesia versus traditional surgical tracheotomy (ST).Methods General data,vital signs,operation time,anesthetics,the amount of bleeding and complications during the procedure were analyzed after reviewing the clinical data of 124 cases under-going radical correction of oral and maxillofacial tumor plus flap transferring and repairing and trache-otomy during May 2013 to May 201 5.Results A total of 124 cases were divided into two groups:PDT group (group P,n =41)and ST group (group S,n =83).There was no significant difference of general data between the two groups.The incision length and operation time were significantly shorter and the amount of bleeding was remarkably lower in group P than those in group S (P <0.05),while the incidence of complications was not significantly different between the two groups.Conclusion PDT has more advantages over traditional ST and is a better airway approach in oral and maxillofacial surgery.

OBJECTIVE To study the distributive properties and susceptibility of yeasts to six antifungal agents. METHODS To analyze the distributive properties of 264 clinical Candida spp isolates and study the susceptibility to amphotericin B,nystatin,fluconazole,ketoconazole,miconazole and clotrimazole.The susceptibility of yeasts was tested according to the National Committee for Clinical Laboratory Standards guideline(NCCLS M27-A2). RESULTS Strains of Candida albicans were the most frequent organism isolated accounted for 62.5% of all the isolates.C.tropicalis,C.glabrata,and C.parapsilosis accounted for 20.8%,12.5%,and 1.9%,the others accounted for only 2.3%.The main infected organs were lungs,urinary tract,and digestive tract;the susceptibility tests showed strains of Candida spp to nystatin,amphotericin B,and fluconazole were more active than to the other antifungal agents.The resistance to triazole antifugal agents could be shown. CONCLUSIONS We should strengthen the diagnosis of Candida spp and strengthen the surveillance on susceptibility of clinical isolates Candida spp so as to help the doctors choose the antifungal agents reasonably.

ObjectiveTo investigate the value of serum creatinine(SCr) to monitor the renal function of patients with spinal cord injury(SCI).Methods1298 SCI patients were investigated in Beijing Charity Hospital from January 2004 to May 2009. 249 healthy people were involved as control. The data of SCr were analysed.ResultsThe level of SCr for the SCI patients was (56.81±14.33) μmol/L with normal distribution, 95% CI was 28.73～84.89 μmol/L; The level of SCr for the healthy people was (75.98±11.34) μmol/L, 95% CI was 57.36～101.80 μmol/L. The level of SCr was significantly lower in the SCI patients comparing to the healthy people (P<0.01). Among the SCI patients, the level of SCr was (59.59±13.76) μmol/L for male while (46.41±11.31) μmol/L for female(P<0.05). There was no difference in level of SCr among different ages of the SCI patients(P>0.05). The characteristics were likely in the two groups. There was no difference in level of SCr between paraplegic (55.54±14.96) μmol/L and quadriplegic (57.67±13.83) μmol/L (P>0.05).ConclusionThe characteristics of level of SCr were likely in SCI patients and healthy people with normal distribution. The level of SCr was lower in SCI patients comparing to healthy people, which was higher for male SCI patients comparing to female SCI patients.

Objective To investigate the incidence of and clinical factors influencing neonatal birth defects from different assisted reproductive technology. Methods Between October 1998 and December 2006,1271 newborns from mothers treated by in vitro fertilization techniques [ including in vitro fertilization (IVF), intracytoplasmic sperm injection (1CSI) and thaw embryo transfer (Thaw-ET) ] matched with 269 newborns from mothers treated by artificial insemination were enrolled in Reproductive Medicine Center in First Hospital Affiliated to Zhengzhou University. Their medical information was analyzed retrospectively to compared neonatal characteristics, the incidence of birth defect and anomalous organs involved between in vitro fertilization group and artificial insemination group. Results In group of in vitro fertilization, those newborns with low birth weight from IVF, ICSI and Thaw-ET were 20. 0% ( 134/671 ), 22. 4% (92/410), 18.9% (36/190)respectively, which were more than 11.5% (31/269) cases in group of artifical semination with statistical significance (P < 0. 05 ). The rates of multiple pregnancy of 23.8% ( 160/671 ), 25.4% (104/410) ,21.1% (40/190) in subgroup of 1VF, ICSI and Thaw-ET were significantly higher than 10. 0% ( 27/269 ) in group of artifical insemination( P < 0. 05 ). The rate of macrosomia in group of in vitro fertilization was significantly lower than that of artificial insemination group (3.9% vs 8. 2%, P <0.05). However, the incidence of birth defect involved in various organs did not show significant difference between two groups ( P>0.05 ). Conclusions The incidence of multiple pregnancy demonstrated obviously increasing trends born with various In Vitro Fertilization techniques, which pave the way to high risk pregnancy. However, the incidence of newborn birth defect was not increased significantly. Thus, to lower occurrence of multiple pregnancy was the key approach to obtain neonates health.

Objective To evaluate the effects on pregnancy outcome of freezing time from oocyte retrieval and thawing method for metaphase Ⅱ human oocytes vitrification. Methods From Mar 2007 to Mar 2009, the clinical outcome of 30 infertile women undergoing vitrified-thawing oocytes of in vitro fertilizationembryo transfer(IVF-ET) in the Reproductive Medical Center of the First Affiliated Hospital of Zhengzhou University was studied retrospectively, including 21 women with double fallopian tube obstruction and 9 women's husband azoospermia. All infertile women were divided into three groups, including 5 cases in group A (freezing between 4 and 5 hours from oocyte retrieval and conventional thawing method), 9 cases in group B (freezing within 2 hours from retrieval and conventional thawing method) and 16 cases in group C (freezing within 2 hours from retrieval and improved thawing method). The vitrified oocytes were preserved for 2 months to I year and thawed for Intracytoplasmic sperm injection (ICSI) and embryo transfer. The outcome of IVF and pregnancy were recorded. Results (1) The rates of oocyte survival was (65±33) % in group B and (72±23)% in group C and the rate of transfer cycle was 9/9 in group B and 16/16 in group C, which were all significantly higher than (16±17) % of oocyte survival and 1/5 of transfer cycle in group A (P = 0. 001,0. 021). However, the rate of oocyte survival and transfer cycle between group B and group C did not reach statistical difference (P > 0. 05). The rate of implantation and clinical pregnancy of (33±38) % and 9/16 in group C were significantly higher (4±11)% and 1/9 in group B (P =0. 033,0. 040).(2)The mean age of women in group C were (28.6±2.1) in oneself oocyte, (28.0±4.6) in donor oocyte and (28.1±3.4) in donor sperm. The rate of oocyte survival was (73±25) %, (88±10) % and (66±25) %. The rate of fertilization rate was (84. 6±0. 9) %, (79. 3±2. 0) % and (82. 8±15.0) %. The rate of implantation was (20. 0±44. 7) %, (33. 0±0. 1) % , (41.6±41.7) %. The rate of clinical pregnancy was 1/5 in oneself cycles,3/3 in donor oocyte cycles, 5/8 banked donor sperm cycles in group C. All above clinical parameters were not statistically different (P >0. 05). (3) In group A, one women underwent IVFET and no clinical pregnancy was observed. One women pregnancy was terminated at two months in group B.The clinical pregnancies rate of group C was 9/16, late abortion occurred in 1 woman, the other 8 women underwent term pregnancy, including 5 male infants and 4 female infants. All of infants showed normal Karyotype. Live-birth rates per warmed oocyte was 5.9% (8/135). The mean gestational weeks and birth weight of the infants were (39. 4±0. 9) weeks and (3574±569) g, respectively. Conclusions Embryo quality and clinical outcome of thawing cycles could be significantly improved when oocyte vitrification was performed within 2 hours from oocyte retrieval and improved thawing method.

OBJECTIVE: To survey the prevalence of obstructive sleep apnea-hypopnea syndrome(OSAHS) in adults aged over 60 years in Dongying city,and analyze the risk factors and the extent of damage to the quality of life for the elderly to provide the basis for prevention and treatment of OSAHS people. METHOD: One thousand subjects were derived from a random cluster sampling in seven districts of Dongying city:they were asked to answer the questions from questionnaires. According to the questionnaire scoring, 100 subjects in high-risk group were selected randomly to make polysomnography monitoring for a whole night,so that the prevalence of the disease was calculated and the related risk factors were analyzed; elderly patients diagnosed with OSAHS were asked to assess the quality of life assessment questionnaire by face to face to understand the quality of life dimensions injury. RESULT: The actual number of completed surveys was 934, and the efficiency was 93.4%. The estimated prevalence of OSARS in elder people defined by apnea-hypopnea index (AHI ≥ 5) was 32.5%; Multivariate analysis revealed that age smoking, family snoring,neck circumference, waist circumference, and abnormality of the upper airway were respectively independent risk factors of OSAHS,and the abnormalities of the upper airway had the most obvious impact on AHI. The damage caused by OSAHS to the quality of life for elderly people followed their daily work life, social relationships, symptoms, alertness, emotional, general health, symptoms. CONCLUSION The estimated prevalences of OSAHS in elder people were high. Actively promoting good habits to older people, weight loss, early detection and correct upper airway abnormalities may reduce the estimated prevalence of OSAHS. In the treatment process, the patient's physician should pay attention to their emotional and groom their psychological problems to improve the quality of life in elder people.
