A new enhancement method is proposed based on the characteristics of fundus images in this paper. Firstly, top-hat transform is utilized to weaken the background. Secondly, contrast limited adaptive histogram equalization (CLAHE) is performed to improve the uneven illumination. Finally, two-dimensional matched filters are designed to further enhance the contrast between blood vessels and background. The algorithm was tested in DIARETDB0 databases and showed good applicability for both normal and pathological fundus images. A new no-reference image quality assessment method was used to evaluate the enhancement methods objectively. The results demonstrated that the proposed method could effectively weaken the background, increase contrast, enhance details in the fundus images and improve the image quality greatly.

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(P<0.05).The allele carrying rate of HLA-DQB1*06/09 in the cervical cancer group was lower than the health control group with statistically significant difference(P<0.05).There was no significant difference of the allele carrying rate of HLA-DQB1*02/05/07/08 between two groups(P>0.05).(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.

Objective To explore the acquired deficiencies of vitamin K-dependent coagulation factors in etiology, clinical characteristics and treatment. Methods Retrospective analysis was performed on the data of etiology, clinical manifestations of 45 patients with acquired deficiencies of vitamin K-dependent coagulation factor. All patients were treated with Vitamin K1 10 -40 mg/d, i. v. , for three months. Some patients with severe blooding were additionally treated with fresh freezing plasma or prothromibin complex. Prothrombin time(PT) and activated partial thromboplastic time(APTT) were measured using Stago automatic blood coagulation analyzer before and after treatment. Ⅱ , Ⅶ, Ⅸ and Ⅹ were measured in some patients. Results Among the 45 cases, no certain cause was found in 19 cases (42.2%), anticoagulant rodenticides poison was a common cause ( 11 cases,42.3% ). The main presentations was hemorrhage, the most common bleeding sites were mucosa (77.8%) (35/45)and hematuria (46.7%) ( 21/45 ). After vitamin K1 treatment, PT and APTT had shortened remarkably from ( 110.35 ± 35.36 ) s,(98.91 ±48.98)s to (13.48 ±2. 17)s,(33.25 ±6.95)s,respectively(t=19.10 and 6.19,Ps ＜0.01)and the activities of factor Ⅱ、Ⅶ、Ⅸ、Ⅹ had rapidly increased from ( 17.48 ± 10.93 ) %, ( 10.23 ± 5.68 )%, ( 11.98 ±4.69)%,(12.93±7.48)% to (70. 12 ±21.31)%,(92.76 ±29. 15)%,(88.64 ±40. 21)%,(63.97 ±20.11)%(t=12.13,14.43,13.27and9. 74,respectively,Ps＜0. 01).Conclusions The histories of patients with acquired deficiencies of vitamin K-dependent coagulation factors are usually hiding, therefore it is easily misdiagnosed. It is worth of detecting PT and APTT in diagnosis and monitoring. Using vitamin K1 10 -40 mg/d is effective and safety.

Objective To investigate the prevalence and risk factors of postpartum depression among female immigrants at Tianhe district of Guangzhou. Methods A total of 2021 migrant women postpartum in three hospitals at Tianhe district of Guangzhou were screened with Center for Epidemiological Survey Depression Scale , (CES-D), Social Support Rating Scale(SSRS) and self-made related factors questionnaire from May to December, 2013. Results This study showed postpartum depression affected 18.31% of migrant women at Tianhe district of Guangzhou. Unconditional logistic regression analysis showed a significant correlation of PPD with birth place , residence time,newborn disease,fetus gender and household income (P < 0.05). Multivariate logistic regression analysis identified birth place,residence time,newborn disease,fetus gender as the risk factors for PPD,household income was negatively correlated with the incidence of PPD with OR value of 0.680;Compared with healthy female immigrants, the total score of social support rating scale,the score of objective support,subjective support and social utilization degree were significantly reduced respectively in female immigrants with PPD. Conclusion The prevalence of PPD was high at Tianhe district of Guangzhou,health education and comprehensive social support system should be offered in order to prevent PPD.

Objective To investigate the effect of different concentrations of dexmedetomidine on the apoptosis of hippocampal neurons in neonatal rat induced by propofol in vitro. Methods Hippocampal neurons of primary cultured neonatal SD rat were divided randomly into three groups. Group C (control group)was normal cultured without any treatment for 12 h; group P (Propofol group)was incubated with 12 μg/mL propofol for 12 h and group DP (Dexmedetomidine + propofol group)was incubated with 0.002 5 ~ 25 μg/mL dexmedetomidine for 30 min, and then further incubated with 12 μg/mL propofol for 12 h. Results Compared with that of group C, the apoptosis rate of hippocampal neurons increased in group P and DP (P < 0.05 or P < 0.01); Compared with that of group P, the apoptosis rate of neurons decreased with the increase of dexmedetomidine concentration in group DP (P<0.05 or P<0.01). The result of transmission electron microscope indicated that compared with group C , group P showed obvious neuronal damage; the nerve cells damage alleviated in group DP, which were negatively associated with the concentration. Conclusions With the concentration ranging from 0.002 5 to 25 μg/mL, dexmedetomidine set pre-incubation and breeding can reduce apoptosis of hippocampus neuron of neonatal rats induced by propofol and the effect is concentration dependent.

Objective:To analyze the causes, influencing factors and trends of dead on arrival cases in children′s Hospital in the past 5 years, aiming to provide direction and basis for reducing the dead on arrival cases of children.Methods:We collected the dead on arrival cases in the department of emergency at Shanghai Children′s Hospital from January 2015 to December 2019, classifed and analysed the gender, age, native place, death season, time of death, and possible causes of death, and then studied the correlation between above factors and the cases.Results:A total of 151 dead on arrival cases were collected.The annual number decreased year by year, and boys were more than girls in gender.Most of them were infants under 1 year old, and nonlocal children were more than Shanghai native.The above differences were statistically significant, but there was no significant difference in the distribution of death season and death time.In terms of the cause of death, perinatal diseases accounting for 33.8%(51/151), those accompanied with severe underlying diseases accounting for 39.1%(59/151), accidental death accounting for 14.6%(22/151), unexplained deaths accounting for 12.6%(19/151). Those distribution differences were statistically significant( χ2=32.497, P<0.001). Meanwhile, there were statistic differences in gender and age of the cases with severe underlying diseases( χ2=4.898, P=0.027; χ2=32.169, P<0.001), and the year and age distributions of the accidental death cases also had significant differences( χ2=16.636, P=0.002; χ2=14.727, P=0.002). Conclusion:To reduce dead on arrival cases of children, we should do a good job in perinatal health care and screening, reduce premature birth and birth defects, actively conduct propaganda to prevent children′s accidental injuries, popularize medical first aid knowledge, and strengthen children′s transport system.

Objective:To study the changes of Th17,regulatory T(Treg) cells and IL-17,IL-23 levels at acute phase and recovery phase in children with Henoch-Schonlein purpura(HSP) in order to further understand the immunological pathogenesis and provide help for treating HSP. Methods:The vein blood samples were collected from 65 children with HSP and 30 normal children. The proportion of Th17 cells and regulatory T cells were tested by FCM and concentration of IL-17 and IL-23 in plasma were tested by ELISA. Results:Compared with normal children,the levels of Th17,Th17/Treg and IL-17,IL-23 were in increase at acute phase in children with HSP(P<0. 05). At recovery phase,that were in decrease compared with the acute phase(P<0. 05),but still higher than the normal children(P<0. 05). Compared with normal children,the level of Treg was in decrease at acute phase in children with HSP (P<0. 01). At recovery phase,that was in increase compared with the acute phase(P<0. 01),but still lower than the normal children (P<0. 01). Among the simplex,abdominal and other type of children with HSP,the levels of Th17,Treg,Th17/Treg and IL-17,IL-23 were same( P>0. 05 ) . At acute phase in children with HSP, Th17 cells percentage had positively correlated with IL-17 levels ( r=0. 880,P<0. 01),IL-23 levels had positively correlated with Th17 cells percentage and IL-17 levels (r=0. 838 or 0. 877,P<0. 01). Conclusion:Th17,Treg,Th17/Treg,IL-17 and IL-23 are involved in the course of the immunological pathogenesis in children with HSP,but the levels of that have no significant difference among simplex,abdominal and other types,further researches need to be done.
