Relationship between HLA-DQB1 allele polymorphism with HPV16 infection and cervical cancer susceptibility in Guangxi Zhuang women / 中国免疫学杂志

Objective:To study the relationship of Guangxi Zhuang women being infected by HPV16 and suffering from cervical cancer with HLA-DQB1 allele polymorphism.Provide clues for seeking hereditary susceptibility gene or resistant gene of cervical cancer of Guangxi Zhuang women.Methods:Chose the cervical cancer diagnosed female patients and health women 171 cases respectively aged between 25 and 45 of Guangxi as subject investigated(people in the two groups were paired by age ±3 years).Took their samples to extract HPV DNA and human genome DNA.Then detected HLA-DQB1 alleles and HPV genetype applying PCR-SSP and molecular diversion hybrid technology.Finally the data were statistically analyzed.Results:(1)The total infection rate of HPV in 171 cases of cervical cancer patient was 91.22%,in which the high-risk virus accounted for 90.76%,HPV16 was the main pathogenic subtypes(43.58%).(2)The allele carrying rate of HLA-DQB1*04 in the cervical cancer group was higher than the health control group with statistically significant difference(P0.05).(3)The occurrence frequency of HLA-DQB1*04 alleles in HPV16 positive cervical cancer patients was significantly higher than HPV16 negative patients with statistically significant difference(P<0.05).Conclusion:HLA-DQB1*04 alleles are probably the susceptibility genes of cervical cancer of Guangxi Zhuang women;HLA-DQB1*06/09 alleles are probably the protective genes of cervical cancer of Guangxi zhuang women;HLA-DQB1*02/05/07/08 alleles seem irrelevant to hereditary susceptibility of cervical cancer of Guangxi Zhuang women.And Guangxi Zhuang women carried HLA-DQB1*04 alleles are more likely to infect HPV16 that increase the risk of cervical cancer.

Relationship between HLA-DQB1 allele as well as expression level of Th1/Th2 cytokines with familial clustering of hepatocellular carcinoma in Guangxi yao / 中国免疫学杂志

Objective:To elucidate the relationship between HLA-DQB1 allele polymorphism as well as the expression level of Th1/Th2 cytokines with familial clustering of hepatocellular carcinoma ( HCC) to provide some evidence for the seeking susceptibility gene or resistant gene of HCC in Guangxi yao,China.Methods:With the same sexuality,age ±5 year,40 members whose families have had two or more HCC patients( high-occurrence families) were selected as the case group,and 40 members whose families have no any cancer patient were selected as the controls.Peripheral blood samples were collected to extract DNA,PCR-SSP was used to detect HLA-DQB1 alleles and ELISA was used to detect IL-2,IL-4 and IL-10.Results:(1) The gene frequency of the HLA-DQB1*02/09 alleles in the case group was higher than that in the controls(P0.05 ).( 2 ) The gene frequency of alleles HLA-DQB1 in HBsAg positive group and HBsAg negative group were never significant difference (P>0.05).(3)The expression levels of IL-4,IL-10 in the case group was higher than that in the control ( P<0.05 ).( 4 ) The expression level of IL-10 in the positive group of the HLA-DQB1*02 allele was higher than that in the negative group of the HLA-DQB1*02 allele ( P<0.05 ).( 5 ) The expression level of IL-4 in the positive group of the HLA-DQB1*09 allele was higher than that in the negative group of the HLA-DQB1*09 allele( P<0.05) .Con-clusion:(1) HLA-DQB1*02/09 seem to be susceptibility genes of hepatocellular carcinoma in high HCC incidence areas of Guangxi yao.(2) There may be not significant correlation bewteen HLA-DQB1 alleles and the susceptibility of HBV infection in high HCC incidence areas of Guangxi yao.( 3 ) The imbalance of IL-4, IL-10 might be associated with familial clustering of hepatocellular carcinoma in Guangxi yao.(4)The imbalance of IL-10 might be due to the carrying of HLA-DQB1*02;the imbalance of IL-4 might be due to the carrying of HLA-DQB1*09.Through the same approaches,these might lead to the phenomenon of familial aggregation of HCC in Guangxiyao.

Status of nursing professional environments and countermeasures / 现代临床护理

Objective To investigate the present situation of nursing professional environments in our hospital and provide theoretical basis for mapping out relevant countermeasures. Method A questionnaire survey was conducted among 338 nurses in our hospital by using the general information questionnaire and practice environment scale (PES). Result The dimensions of PES by their average scores in descending sequence included leadership and ability of nurse administers, doctor-nurse cooperation, foundation for high quality care nurses′participation in hospital affairs, and sufficient manpower and resources. Conclusion In order to provide good and healthy work environment for nurses, nursing administrators should provide enough nursing manpower resoures and apply excitation mechanism in their hospital.

Clinical significance of intermittent sinusoidal fetal heart rate at third trimester / 中华妇产科杂志

Objective To investigate clinical significance of intermittent sinusoidal feial heart rate at third trimester.Methods From Jan 2002 to Dec 2010,48 pregnant women at 33 to 41 gestational weeks undergoing electronic fetal heart rate(FHR)monitoring presented with intermittent sinusoidal FHR in Department of Obstetrics and Gynecology,Second School of Clinical Medicine,Jinan University were enrolled in this retrospective study.Twenty-one cases were categorized into continuous group(i.e.with sinusoidal feature and a constant duration≥10 minutes).while the other 27 cases were categorized iuto intermittent group(i.e.with a duration＜10 minutes).In the mean time.76 normal cases were chosen randomly matched as control group.Blood gas and hemoglobin were measured in umbilical artery after fetal head delivery.General neurological system examination were performed in those fetus in hospitalization.The outcome of those fetuses was compared.Results (1)Neonatal complications:the rate of asphyxia,meconium-stained amniotic fluid and fetal anemia were 63%(17/27),33%(9/27)and 63%(17/27)in group of intermittent sinusoidal FHR,which were significantly higher than 1%(1/76),4%(3/76),3%(2/76)in control group(P＜0.05).When compared with 67%(14/21),52%(11/21),76%(16/21)in group of continuous sinusoidal,the statistical difierence were not observed(P＞0.05).(2)Blood gas in neonate:the rates of pH less than 7 were 18%(5/27)in intermittent group,52%(11/21)in continuous group and 0 in control group,which all reached statistical difference among those three groups(P＜0.05).(3)Brain damage and death:the rates of brain damage and death were 48%(13/27)and 11%(3/27)in intermittent group,81%(17/21)and 43%(9/21)in continuous group,and 0 in control group,which all showed significant difference between them(P＜0.05).Conclusion Intermittent and continuous sinusoidal FHR are typical graphics of severe fetal anemia at third trimester.Intermittent sinusoidal FHR is indicative of serious fetal hypoxia.
