Apply PDCA cycle theory to the progress management of the national 863 program aimed at the problem of paying more attention to program application and achievement awards,but ignoring progress management.It indicated that the quality of research has been improved.So,scientific research administrators should renew their management knowledge,to improve the ability of scientific research management.

To analyze maternal and neonatal complications among late preterm birth cases and to investigate risk factors of late preterm birth. Methods This was a retrospective analysis of 258 late preterm cases (late preterm group) born in Peking University First Hospital from January 1, 2009 to December 31, 2010. Maternal comorbidity and complications, delivery modes, and neonatal complications of these 258 late preterm infants were compared with 308 term cases (term group) during the same period. Statistical analysis was performed usingχ2 test, Fisher's exact probability test, t test and logistic regression. Results In Peking University First Hospital, late preterm births accounted for 3.9%(258/6 695) of live births and 60.1%(258/429) of preterm births. The incidence of the following maternal complications among the late preterm group was higher than that among term group(all P<0.05): severe pre-eclampsia [7.4%(19/258) vs 1.0%(3/308), χ2=15.35]; preterm rupture of membrane [42.6%(110/258) vs 15.3%(47/308), χ2=52.49];cervical insufficiency [1.9%(5/258) vs 0.0%(0/308), Fisher's exact test];placenta previa[3.5%(9/258) vs 0.6%(2/308), Fisher's exact test] and placental abruption [2.7%(7/258) vs 0.3%(1/308), Fisher's exact test]. Severe pre-eclampsia was the major risk factor leading to late preterm birth. The incidence of the following neonatal complications among the late preterm group was higher than that among term group (all P<0.05):respiratory distress syndrome (NRDS) [11.6%(30/258) vs 1.6%(5/308), χ2=24.22]; hyperbilirubinemia [64.3%(166/258) vs 39.6%(122/308),χ2=34.36];electrolyte disturbance [12.8%(33/258) vs 1.6(95/308),χ2=27.96];hypothermia [7.0%(18/258) vs 2.9%(9/308),χ2=5.08];infectious pneumonia[13.6%(35/258) vs 3.2%(10/308), χ2=20.43]; leukoencephalopathy [3.1%(8/258) vs 0.3%(1/308), χ2=5.25]; low body temperature [18.6%(48/258) vs 3.6%(11/308),χ2=33.98] and neonatal asphyxia [6.2%(16/258) vs 1.0%(3/308),χ2=11.86]. The incidence of the following neonatal complications among late preterm infants born at<35 weeks gestation was higher than that among late preterm infants born at≥35 weeks gestation (all P<0.05):NRDS [30.4%(14/46) vs 7.5%(16/212) ,χ2=19.26];hyperbilirubinemia [91.3%(42/46) vs 58.5%(124/212), χ2=17.74]; electrolyte disturbance [21.7%(10/46) vs 10.8%(23/212), χ2=4.02]; intracranial hemorrhage [8.7%(4/46) vs 1.9%(4/212),χ2=3.88];leukoencephalopathy [10.9%(5/46) vs 1.4%(3/212),χ2=8.32] and neonatal asphyxia [15.2%(7/46) vs 4.2%(9/212), χ2=6.05]. Conclusions Severe pre-eclampsia is the major risk factor leading to late preterm birth. The incidence of complications among late preterm infants is higher than that among term infants. If a pregnancy has to be terminated because of maternal disorders, the pregnancy period should be extended to 35 weeks if it permits.

Objective To investigate the effect of Zidan decoction containing serum on endometrial receptivity in uterine immunity environment,and then to discuss if it's effect on endometrial receptivity through its controlling the expression of cell factors which related to endometrial receptivity.Methods Mice's endometrium tissue samples and uterine Natural Killer (UNK) cells were obtained from pregnant mice on gd 4.5 days and gd 12.5 days.After endometrial glandular epithelial cells,endometrial stromal cells and UNK cells were separated through primary culture,epithelial cells and endometrial stromal cells at rate of 1 ∶ 1 a certain concentration UNK were mixed together and highly purified-cultured.Different concentrations of Zidan decoction was acted on the culture solution.FBS,black and aspirin control group were setup for contrast.The expression of LIF and VEGF which influenced by Zidan decoction in the immunity environment was assayed by Realtime-PCR.Results The expression of LIF and VEGF was significantly increased in the immunity environment of uterine (in 10％ Zidan decoction group,10％ aspirin group and 10％ blank control group:LIF was 2.10±0.20,1.98±0.14,0.90±0.05 separately,and VEGF was 3.17±0.31,2.52±0.09,0.92±0.06respectively,P＜0.05).Conclusion Zidan decoction could improve endometrial receptivity by increasing the expression of cell factor which related to endometrial receptivity with the help ofUNK paracrine.

0.05). Conclusion When TOFR recovers to 0.55,antagonism of residual neuromuscular blockade is still necessary.Different doses of neostigmine may antagonize vecuronium-induced residual neuromuscular blockade,and lower dose of neostigmine(10-20 ?g/kg) is recommended.

To observe the clinical outcome of implanting AcrySof lQ Toric intraocular lens to correct corneal astigmatism in cataract surgery, and to evaluate the result and rotational stability of AcrySof lQ Toric after cataract surgery.
●METHODS: A retrospective study of 26 eyes in 21 cataract patients with corneal astigmatism. All patients implanted AcrySof lQ Toric intraocular lens. The preoperative and postoperative uncorrected visual acuity ( UCVA ), best corrected visual acuity ( BCVA ), preoperative corneal astigmatism, anticipated residual astigmatism, total astigmatism, postoperative residual astigmatism and Toric lens axis were detected and measured.
●RESULTS: All patients' visual acuity and best corrected visual acuity improved significantly. The mean refractive cylinder decreased significantly after surgery from (2. 05± 0. 57)D to (0. 55±0. 33)D (t = 13. 574, P<0. 05). There was no significant difference between preoperative ( 0. 47 ± 0. 19)D and postoperative corneal astigmatism (t = 1. 149, P > 0. 05 ). Three months after surgery, there was no significant difference between preoperative (2. 01±0. 58)D and postoperative (-1. 89±0. 53) D corneal astigmatism (t =1. 908, P> 0. 05). The rotation of intraocular lens were <20°, the mean rotation was 3. 65°±2. 86°.
●CONCLUSlON: The AcrySof lQ Toric lens make cataract patients enjoy the better UCVA including good rotational stability in the correct of corneal astigmatism. The AcrySof lQ Toric implantation is an effective option for the correct of preexisting corneal astigmatism in cataract surgery.

Objective To explore risk factors for coronary artery aneurysms (CAA) in children with Kawasaki disease (KD),and reduce the rate of serious sequelae of cardiovascular diseases.Methods All the patients were diagnosed as KD in Children’s Hospital Affiliated to Medical College of Zhejiang University from January 2009 to January 2014.A total of 679 cases was included,and 42 with concurrent CAA,181 with concurrent coronary artery expansion (CAD),and 456 without coronary artery damage cases (non-coronary artery lesion,NCAL).Coronary artery damage was related to factors such as gender,age,fever,white blood cell count (WBC),hemoglobin (Hb),platelet count (PLT),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),alanine aminotransferase,serum potassium,plasma amino terminal brain natriuretic peptide precursor (NT-proBNP),and acrylic ball resistance.SPSS 18.0 software package was used for risk factor analysis.Qualitative data using chi-square test,was used to analyze the high risk factors of CAA group,and logistic multivariate regression analysis was also used.Results Chi-square test showed that male,with febrile days ＞ 14 d,NT-proBNP ≥ 1 000 ng/L,immunoglobulin resistance was more likely to have KD concurrent CAA (P ＜ 0.05).Multiple Logistic regression analysis showed that male [OR =4.092,95％ CI (1.514,11.060),P =0.004],febrile days ＞14 d [OR =12.436,95％ CI (4.599,33.631),P =0.000],NT-proBNP≥ 1 000 ng/L [OR =3.305,95％ CI (1.401,7.794),P =0.005],and immunoglobulin resistance [OR =3.842,95 ％ CI (1.562,9.453),P =0.000] were independent risk factors for KD concurrent CAA.Conclusions Male children,febrile days ＞ 14 d,NT-proBNP≥ 1 000 ng/L,and immunoglobulin resistance were independent risk factors of CAA.
