Objective To analyze the coincidence situation of the results of neonatal ABO blood group reciprocal stereotypy with crossmatching test of allotype blood and to investigating the limitations of cross-matching test in infant blood transfusion and effec-tive measures for ensuring the neonatal safe blood transfusion.Methods The micro-column gel test was adopted to identify the ABO blood group and conduct the crosshatching test of allotype blood in 1 095 cases of neonatal blood samples.Results Among the 1 095 samples,the detected rates of weak A and weak B antigen were 3.99% and 17.93% respectively,and the weak B antigen was predominant.The negative rates of anti-A and anti-B antibody were 53.72% and 60.70% respectively;in the cross-matching test with allotype blood,the main side without appearing agglutination accounted for 52.87% and weak agglutination accounted for 33.27%,and the secondary side appearing weak agglutination accounted for 9.49%.Conclusion The maturity of antibody and an-tigen and the coincidence rates of group typing and reciprocal stereotypy in the newborns are less than those in the adults;so blood transfusion according to the cross-matching test results has certain limitation;high attention should be paid to the accuracy of neo-natal ABO blood type,the individual blood transfusion strategy in the newborn should be determined in order to avoid hemolytic blood transfusion reaction caused by ABO allotype blood transfusion and ensure the blood transfusion safety in newborns.

Objective To study the pathogenicity of ureaplasma urealytieum serotype 3 (UU3) with different concentration in the genital tract of the mice. Methods A total of 156 Kunming mice were divided into 4 groups randomly, including group A, B, C (48 mice in every experimental group) and control group.(12 mice in control group). UU3 at concentration of 1×107eopy/g (group A), 1×106copy/g (group B),1×105copy/g (group C) were inoculated into 48 mice in every experimental group intravaginal]y, in the mean time, culture medium of UU was given into 12 mice in control group. They were neeropsied at 1, 3,7, 14, 21, 35 days of postinoeulatien randomly, which included 8 mice of every experimental group and 2 mice of control group every time, and to detect UU3 expression from cervical secretions by FQ-PCR andobserving the pathogenicity rate in tissues of cervix, endometrium, fallopian tube by light microscope and calculate the morbidity rate. Results (1) The total positive rates of UU3 were 63% (30/48) in group A,50% (24/48) in group B, 17% (8/48) in group C, which showed a significant difference(P<0.01).And at 1,3,7,14,21,35 days of postinoculation, the positive rates of group A were 8/8,7/8,6/8,5/8,4/8 and 0,group B were 7/8,5/8,5/8,4/8,3/8 and 0,group C were 3/8,2/8,2/8,1/8,0 and 0;all mice in control group were zero. At all time points, there were statistical difference in the positive rate among three experimental groups only at 1 day (P<0.05 ). (2) In the positive mice, their UU3 quantity concentration at 1,3,7,14,21 days were 1.70×107, 8.26×106, 4.04×106, 2.86×106,and 2.41 x105 copy/g in group A; 3.75×106, 2.56×106 , 1.37×106, 6.72×105, and 1.12 x 105 copy/g in group B, and 1.45×105,1.07×105, 5.43×104, 4.68×103, and 0 copy/g in group C. There were statistical difference among experimental groups at all time points except 21 days (P<0.05). Comparing the concentration among all time points of every group, both group A and B showed a significant difference(P<0.05) ,group C didn't reach it( P>0.05). (3) The total pathogenicity rates of three groups were significant different at 7-35 days, which were 56% (18/32) in group A, 44% (14/32) in group B, 6% (2/32) in group C (P<0.01 ). And at 7,14,21,35 days of postineculation, the pathogenicity rates in group A were 5/8,5/8,4/8 and 4/8, group B were 4/8,4/8,3/8 and 3/8, group C were 1/8,0,1/8 and 0; all mice in control group were zero, which demonstrated significant difference only at 14 days (P<0.05), no other statistical difference were observed (P>0.05) . Conclusions The pathogenicity of UU3 varies with different concentration in genital tract of mice. When UU3 concentration is more than 1×106 copy/g, the susceptibility to infection was intensified significantly.

Background and purpose:With the recognition of prognostic factors and application of surgical- pathological staging,the treatment strategy of endometrial cancer has greatly changed.In this study,we investigated the treatment strategy,survival rate and prognostic factors of endometrial cancer.Methods:Five hundred and fifty-nine patients of endometrial cancer underwent primary surgical treatment from January 1996 to December 2006 in Cancer Hospital,Fudan University.The clinicopathologic parameters and prognosis were analyzed retrospectively.Results: Patients were followed up with the median period 36 months,25 cases experienced local relapse,24 cases were found to have distant metastases.The 3-year overall survival(OS)was 88.7%,3-year and 5-year disease free survival(DFS) was 82.7% and 80.9%.The 3-year overall survival(OS)were 95.5% in stageⅠ,95.3% in stageⅡ,75.9% in stageⅢand 32.4% in stageⅣrespectively(P

Objective To determine the serum level of pepsinogenⅠ,Ⅱ(PGⅠ,PGⅡ) and PGⅠ/Ⅱin the residents from Zhuanghe county,a high risk area of gastric cancer in North China,and to explore their distribution as well as related factors.Methods Serum PGⅠand PGⅡlevels were detec- ted with ELISA method in 6990 subjects.Gastric diseases were diagnosed by endoscopy and histopatho- logic examination.Serum H.pylori-IgG antibody was determined by ELISA method.Results The me- dian values for PGⅠ,PGⅡ,PGⅠ/Ⅱwere 86.9/?g/L,10.6/zg/L and 8.1 respectively.Serum PGⅠand PGⅡin male(95.2?g/L,12.1?g/L) were significantly higher than those in female(79.7?g/L, 9.4?g/L;P=0.000),PGⅠ/Ⅱratio(7.9) was significantly lower in male (8.3,P=0.000).There were significantly decrease in PGⅠ/Ⅱratio along with age increase.PGⅠ/Ⅱratio decreased signifi- cantly following with progression of gastric mucosa from normal (10.4) to non-atrophic lesions(8.8) and to atrophic lesions (6.6).Serum PGⅠand PGⅡin H. pylori positive subjects (88.7?g/L,11.4?g/L) were significantly higher than those in H.pylori negative subjects (81.4?g/L,8.4?g/L;P= 0.000),PGⅠ/Ⅱratio(7.7) was significantly lower in H.pylori positive subjects (9.6,P=0.000). For patients with atrophic lesions,the area under the PGⅠ/ⅡROC curve was 0.622.The best cut-off point for PGⅠ/Ⅱwas 6.9,with sensitivity of 53.2%,and specificity of 67.5%.Factors linked to PGⅠ/Ⅱwere identified using multinomial logistic regression:male (OR:1.151,95% CI:1.042—1.272, P=0.006),age=61(OR:1.358,95% CI:1.188—1.553,P=0.000),atrophic lesion(OR:2.075,95% CI:1.870—2.302,P=0.000),and H.pylori infection (OR:1.546,95% CI:1.368—1.748,P= 0.000).Conclusions The serum PG levels are significantly skewed from normal distrubition in the residents of Zhuanghe county,and affected by age and gender,as well as associated with gastric diseases and H.pylori in- fection.Compared with PGⅠand PGⅡalone,PGⅠ/Ⅱis more suitable for screening gastric cancer.

AlM: To evaluate the application of phacoemulsification of different nucleus density using ozil and traditional mode.METHODS: A total of 89 eyes (72 patients ) ( visual acuity was of 0. 6 and above after 1mo follow - up) of different nucleus density level (LOCS Ⅱ criteria grade Ⅲ 46 eyes, grade Ⅳ and more 43 eyes ) were randomly assigned into 2 groups: ozil group (group A), grade Ⅲ 22 eyes (torsional energy 80% lP on);grade Ⅳ and more 17 eyes (torsional energy 100% lP on); Traditional mode group(group B), grade Ⅲ 24 eyes (energy 50% ), grade Ⅳ and more 26 eyes (energy 60% ~ 70% ) . All surgeries were performed by the same experienced surgeon,who use the chop to split the nucleus in the application of phacoemulsification. lntraoperative parameters were total equivalent pawer ( TEP ), cumulative dissipated energy ( CDE ) and effective phaco time ( EPT ) and surgical complications. The effectiveness of the two modes in dealing with hard - core cataract phacoemulsification were compared.RESULTS: GradeⅢ nucleus dealing: TEP of ozil group was significantly higher than that of the traditional mode group [(24.58±7.78)% vs (13.84±1.97) %]and EPT of ozil group was significantly lower than that of the traditional mode group (50. 59±14. 73 s vs 60. 19±9. 04 s, P<0. 05). CDE showed no difference between two groups [(13.12±6.03)% vs (13.38±2.85)]. Grade Ⅳ and more nucleus dealing: CDE [( 34. 10 ± 13. 48 )%] and EPT (104. 64±32. 4s) of the ozil group was higher than CDE [(30. 31 ± 13. 48)%] and EPT (93. 01 ± 41. 01s) of the traditional mode group, but there were no difference between two groups. Obstacles in the needle of phacoemulsification surgery: ozil group 4/17, traditional mode group 2/26 (χ2=2. 16, P=0. 14).CONCLUSlON: Bothozil and traditional mode can deal with all kinds of nucleus effectively and safely. Ozil mode is more efficacy and quick deal in gradeⅢnucleus. With the increase of nucleus hardness, the traditional mode still have the advantage of high efficiency and no obstacle to dealing patients with grade Ⅳ and more nucleus. Choose according to different nuclear hardness ultrasonic model can improve the operation efficiency and security.

Objective To observe the effects of epidermal growth factor (EGF) on cell proliferation and cell cycle of cultured bovine corneal endothelial cells. Methods Bovine corneal endothelial cells were cultured with different concentrations of hEGF (1, 10 and 100 ng/mL). MTT test was performed to evaluate the cell proliferation. The bovine corneal endothelial cells were divided into two groups:control group (cultured in DMEM) and EGF-stimulated group (cultured in DMEM with EGF). Flow cytometry was performed to determine the cell cycle phases on the third and seventh day. Results Compared with the control, EGF enhanced the cell proliferation in a dose-related response. 10 ng/mL and 100 ng/mL EGF were much more effective than 1 ng/mL.On the third day, S phase cells accounted for 24.5% and G_2-M phase cells 0.08% in the control group,while 24.6% and 0.06%, respectively in the EGF-stimulated group. However, on the seventh day, those came to 20.8% and 0.41% in the control group, and 18.2% and 1.55% in the EGF-stimulated group,indicating a significant change in the cell cycle (P

OBJECTIVE:To provide reference for improving propaganda level and effect of rational drug use. METHODS:Questionnaire survey was designed to investigate the recognition,attitude and demand of consumers in retail pharmacies,students in parts of pharmaceutical universities and their parents and patients in parts of hospitals in more than 10 provinces(autonomous re-gions and municipalities)for propaganda of rational drug use,and the results were statistically significant. RESULTS:The question-naires ranged from 100 to 2 000 in each province (autonomous region and municipality),and totally 11 700 questionnaires were sent out,11 490 were received with recovery of 98.2%;10 980 were effectively received with effective recovery of 95.6%. 78.4%respondents heard of the concept of rational drug use,proportion of young and middle-aged people in 18-44 years old was signifi-cantly higher than other age group,the proportion was significantly increased by the improvement of education,and the proportion of people closer to the city was higher(P<0.001);the respondents who can fully understand the content of the propaganda account-ed for 22.7%,while higher education held higher proportion on“fully understand”,and people closer to the city held higher pro-portion on“fully understand”and“partially understand”(P<0.001);only 9.5% respondents could fully trust propaganda activity, proportion of choosing“partially trust”was generally increased by the improvement of education(P<0.001);and 69.1% respon-dents hoped to obtain relevant knowledge,people who had more purchase frequencies showed stronger willing(P<0.001);the top 3 preferences of respondents for propaganda forms were“face to face guidance from physicians and pharmacists”,“reading drug in-structions”and“reading professional books”. CONCLUSIONS:With insufficient recognition on rational use of drugs,coverage of propaganda about rational drug use needs further expand,public understanding of propaganda contents about rational drug use is fairly limited and people’s trust level towards propaganda is not high,but the public has strong desires to obtain the knowledge about rational drug use. Therefore,various means should be adopted to improve the effects on propaganda of rational drug use.
