METHODS: Cation exchange chromatography on CM-52 and ultrafiltration were used to separateα-Lfucosidase (AFU) from crude extract of liver cancer tissue. 4-methylumbelliferyl-α-L-fucopyranoside was used as a fluorescent substrate to quantify the purified AFU activity in each step. A polyclonal antibody (pAb) against the purified AFU was obtained by anion exchange chromatography on DEAE-52 after ammonium sulfate fractionation and ultrafiltration. Immuohistochemical staining was used to observe the expression of AFU in malignant and adjacent liver tissues. RESULTS: Humanα-L-fucosidase was purified 74-fold to apparent homogeneity with 15% yield. SDSPAGE indicated the presence of one subunit of molecular weight of 55 Ku. The specific activity of AFU in pooled fraction by chromatography was 10085 IU/mg. Western blot analysis indicated that the pAb could recognize one protein band of molecular weight of 55 Ku. The expression of AFU was observed in cytoplasm membrane of liver cancer tissue but not in that of adjacent tissue. CONCLUSION: The purifiedα-L-fucosidase from primary hepatocarcinoma (PHC) is different in its properties fromα-L-fucosidase in human other organs. The polyclonal antibody prepared in this experiment can be applied to the diagnosis of PHC.展开更多

This study was undertaken to assess the optimal pathway to implant the drug delivery system (DDS) in the different ways of resecting PHC so as to offer a valuable reference to clinical implantation of the DDS. METHODS: One hundred and ninety cases were divided into two groups according to whether the tumors were resected completely (A) or not (B). Groups A and B were subdivided into three groups a, b and c according to the pathway selected for DDS implantation. The patients in subgroup a received DDS implantation through both the hepatic artery and portal vein (A+P-implanted group), the patients in subgroup b received DDS implantation through the portal vein (P-implanted group), and the patients in subgroup c received DDS implantation through the hepatic artery (A-implanted group). RESULTS: The 1- and 3-year recurrent rates of subgroup c in group A were higher than those of subgroup b, and there was no significant difference between subgroups a and b. Compared with subgroups a and c, the 1- and 3-year survival rates of subgroup b were similar to those of group a but higher than those of group c. The 1- and 3-year survival rates between subgroups a and b in group B were significantly different. The prognosis of subgroup c was lower than that of subgroup a and no significant difference was observed between subgroups b and c. CONCLUSIONS: The DDS should be implanted into the portal vein when PHC is resected completely. It may be better to implant it into both portal vein and hepatic artery if the tumor cannot be completely resected.展开更多

Antigens and antibodies ofHBV were determined by enzymeimmune assay. Antibodyto HCV IgG was detected by enzyme-linked immunoab-sorbent assay.Results: The positive rate of autoantibody was 27.3%(38/139) in 139 PHC patients. The main type of au-toantibodies in PHC was anti-nuclear antibody (36/38, 94.7%); others included anti-smooth muscle anti-body(2/38, 5.3% ), anti-mitochondria antibody(1/38, 2.6%), anti-midbody antibody (1/38, 2.6%), andanti-liver cell membrane antibody(2/38, 5.3%).Conclusions: Detecting autoantibodies in PHC patientsis of significance in studying the mechanism of au-toimmune reaction and etiology in PHC. The diversityof autoantibodies might result from a wide variety ofetiological factors involved in PHC development, andfrom a wide variety of overexpressed or mutated pro-teins involved in repeated cycles of necrosis and regen-eration in hepatocarcinoma development.展开更多

Microwave therapy was applied to both groups by double leads, 60 W, 800 sec once a week for two weeks. To the treated group, SQM was given additionally through oral intake of 20 ml, three times a day for 1 month. The changes in tumor size, main symptoms, serum level of alpha-fetoprotein (AFP), immune function and adverse reaction were observed after treatment and the immune parameters of the patients were compared with 30 healthy persons in the normal control group. Results: (1) In the SQM treated group, after treatment 3 patients got completely remitted (CR), 24 partial remitted (PR), 4 unchanged (NC) and 5 progressively deteriorated (PD), the effective rate being 75.00%; while in the control group, 1 got CR, 19 PR, 9 NC and 7 PD, the effective rate being 55.56%. Comparison of the effective rate between the two groups showed significant difference (P<0.05). (2) AFP level decreased after treatment in both groups, but the decrement in the treated group was significantly higher than that in the control group (P<0.01). (3) After treatment, in the treated group, CD3+, CD4+, CD4+/CD8+ and NK activity were improved, Karnofsky scores increased and liver function bettered, with these improvements significantly superior to those in the control group (P<0.01). (4) The improvement in symptoms such as hepatic region pain, fever, weakness, poor appetite and jaundice in the treated group after treatment was also superior to that in the control group (P<0.01). (5)The 12-month, 18-month and 24-month survival rates were higher and the recurrence rate was lower in the treated group than those in the control group, showing significant difference (P<0.05). Conclusion: Combined therapy with SQM and microwave coagulation could not only kill the tumor and residue tumor cells to prevent recurrence, but also enhance the cellular immunity of organism. It is one of the effective therapies for patients with middle-advanced hepatocarcinoma, who have lost the chance of surgical operation. It could improve clinical symptoms, elevate the quality of life, prolong the survival period of patients, but shows no evident adverse reaction.展开更多

Methods: A total of 121 cases of PHC by TACE after 1-2 months of surgery was retrospectively analyzed, followed up and analyzed the free survival time and the factors related to tumor-free survival. Results: In all 121 cases, 1-, 2-, and 3-year tumor-free survival rates were 72.73%, 46.21% and 26.93%, respectively. Gender, age, HBV infection, tumor size, capsule is complete, degree of differentiation and the presence of vascular thrombosis were put into the COX proportional hazards model of survival time to select the influential variables. In the clinical data of all variables entering COX proportional hazards model, tumor size, tumor differentiation and the presence of vascular thrombosis were statistically significant contributions to the model. In the tumor diameter less than or equal 10 cm [P = 0.040, Exp (B) = 2.210], vascular thrombosis [P = 0.039, Exp (B) = 2.922] and the lower degree of tumor differentiation [P = 0.035, Exp (B) = 3.038], the risk of tumor recent recurrence increased. Conclusion: Tumor size, differentiation, and the presence of vascular thrombosis are the independent risk factors affecting the prognosis of PHC after TACE.展开更多

Design: Cross sectional. Setting: Primary Health Centers Participants: Pregnant women and Heads of health facilities. Methods: Two hundred respondents each from urban and rural areas primary health centres were proportionately selected from 18 primary health centers using simple random sampling. Exit interviews were conducted using the antenatal care exit interview form of the Safe Motherhood Needs Assessment package. In-depth Interviews were conducted with the heads of selected facilities. Data was analysed using descriptive statistics and Chi square test and content analysis for indepth interview. Results: More respondents 58 (29.3%) from the urban areas had the minimum contents compared to 41 (20.7%) of the rural respondents (p < 0.05) and 178 (90.8%) of the urban were taught a range of health education topics compared to 177 (88.5%) (p = 0.45). Urban respondents were about 1.6 times more likely to receive the minimum contents than rural respondents. In-depth interview results explicated the facilitating factors and challenges to focused antenatal care in the study areas. Conclusion: The findings of this study is consistent with other studies establishing the fact that better health service is available to urban residents than rural residents;however, this study has succeeded in comparing the documented standard of antenatal care with what was being practiced in the selected PHCs of the state. The basic contents of focused antenatal care in Ekiti state were received by a small proportion of the respondents, suggesting that focused antenatal care had not fully translated into quality service;one major challenge to the delivery of standard antenatal care was inadequate number of skilled health workers especially in the rural areas. The gap between quality and utilisation of antenatal in urban and rural areas is gradually being closed up;this success should be improved upon and maintained.展开更多

The toolkit included checklists for physical environment and signage properties. This study matched the current physical environment properties of DHA’s PHC Health Centers against WHO’s recommendations. This is a cross sectional descriptive study that included visits to all 12 Primary Health Care Centers in Dubai city during August-September 2016 with the objective to assess the degree of fulfillment of current properties of Health Centers building to the recommendations of WHO as listed in “Age-friendly Primary Health Care Centres Toolkit” [1]. The study found that 81.86% of physical environment properties are matching the recommendation of WHO, while signage matching was 44.6%. The study concluded that most PHC properties have a physical design that met WHO’s recommendations. The two major deviations were accessibility by public transportations and presence of grab bars. Factors that had a significant impact on design were compliance with multiple international and local standards, the availability of private cars, and the availability of wheel chairs. Signage in DHA’s health centers followed a central plan that differed from WHO’s recommendations.展开更多

This study aims to assess the level of patient satisfaction with primary healthcare services in Riyadh, Saudi Arabia, identify social factors affecting satisfaction, and determine the reasons behind dissatisfaction and how to improve satisfaction. The study employed a cross-sectional observational design and included a random sample of 400 patients from primary healthcare centers in Riyadh. Data were collected using an electronic questionnaire and analyzed using SPSS software. The study found that patients were generally satisfied with the primary healthcare services provided in Riyadh, with high levels of satisfaction reported for booking appointments, triage services, and emergency care. However, some aspects of the healthcare experience, such as long waiting times and the physical design of healthcare centers, need improvement. These findings can be used to inform the development of policies and interventions aimed at enhancing healthcare quality in Saudi Arabia.展开更多

RESULTS: The 1- and 3-year recurrent rates of subgroup c in group A were higher than those of subgroup b, and there was no significant difference between subgroups a and b. Compared with subgroups a and c, the 1- and 3-year survival rates of subgroup b were similar to those of group a but higher than those of group c. The 1- and 3-year survival rates between subgroups a and b in group B were significantly different. The prognosis of subgroup c was lower than that of subgroup a and no significant difference was observed between subgroups b and c. CONCLUSIONS: The DDS should be implanted into the portal vein when PHC is resected completely. It may be better to implant it into both portal vein and hepatic artery if the tumor cannot be completely resected.

文摘The expressions of ets-2 ,IGF-Ⅱ,C-myc and N-ras in 12 pairs ofhuman primary hepatocellular carcinoma(PHC)and tumor-adjacent tissues are presentedin this paper.The results showed that there was at least one of the four oncogenesstudied over-expressed in the 12 pairs of samples.Ets-2 was the most commonly ex-pressed oncogene seen in all the PHC and tumor-adjacent tissues,with 3.5 and 2.4 Kb asthe major two bands,which are different from the evenly expressed 4.5 ,3.5 and 2.4 Kbbands in the normal control livers.In 6 tumor-adjacent tissues,the expression ofets-2 was higher than that in PHC.IGF-Ⅱ was expressed as 5.0 and 2.0 Kb fetaltranscripts in PHC and tumor-adjacent tissues,while in the normal control livers thetranscript was 5.6 Kb only.In one tumor-adjacent tissue there were IGF-Ⅱ fetal tran-scripts ,but in the corresponding PHC no IGF-Ⅱ transcripts were detected .N-raswas expressed as 4.0 kb band in 8 out of 12 PHC and in 6 out of 12 tumor-adjacent tis-sues.In two cases the expression of N-ras was higher in tumor-adjacent tissues than inPBC.5.6 and 2.6 Kb N-ras transcripts were also detected in one pair of PHC and tumor-adjacent tissues and in two tumor-adjacent tisues only,together with the 4.0 Kbtranscript.C-myc was expressed as 4.0 Kb band in 9 out of 12 PHC and in 6 out of12 tumor-adjacent tissues.One tumor-adjacent tissue had higher C-myc expression thanPHC In two PHC ,a 2.2 Kb C-myc transcript was also detected.The roles and rela-tionships of these oncogenes in the carcinogenesis of human PHC are discussed.
文摘Objective: To ascertain that standard antenatal care (Focused antenatal care) is being received at the Primary Health Care level in urban and rural areas of Ekiti State and to determine the facilitating factors and challenges to the practice of FANC in urban and rural areas. Design: Cross sectional. Setting: Primary Health Centers Participants: Pregnant women and Heads of health facilities. Methods: Two hundred respondents each from urban and rural areas primary health centres were proportionately selected from 18 primary health centers using simple random sampling. Exit interviews were conducted using the antenatal care exit interview form of the Safe Motherhood Needs Assessment package. In-depth Interviews were conducted with the heads of selected facilities. Data was analysed using descriptive statistics and Chi square test and content analysis for indepth interview. Results: More respondents 58 (29.3%) from the urban areas had the minimum contents compared to 41 (20.7%) of the rural respondents (p < 0.05) and 178 (90.8%) of the urban were taught a range of health education topics compared to 177 (88.5%) (p = 0.45). Urban respondents were about 1.6 times more likely to receive the minimum contents than rural respondents. In-depth interview results explicated the facilitating factors and challenges to focused antenatal care in the study areas. Conclusion: The findings of this study is consistent with other studies establishing the fact that better health service is available to urban residents than rural residents;however, this study has succeeded in comparing the documented standard of antenatal care with what was being practiced in the selected PHCs of the state. The basic contents of focused antenatal care in Ekiti state were received by a small proportion of the respondents, suggesting that focused antenatal care had not fully translated into quality service;one major challenge to the delivery of standard antenatal care was inadequate number of skilled health workers especially in the rural areas. The gap between quality and utilisation of antenatal in urban and rural areas is gradually being closed up;this success should be improved upon and maintained.
文摘The WHO project for conforming PHC to requirements of all age groups has resulted in publishing a toolkit for age-friendly PHC in 2008. The toolkit included checklists for physical environment and signage properties. This study matched the current physical environment properties of DHA’s PHC Health Centers against WHO’s recommendations. This is a cross sectional descriptive study that included visits to all 12 Primary Health Care Centers in Dubai city during August-September 2016 with the objective to assess the degree of fulfillment of current properties of Health Centers building to the recommendations of WHO as listed in “Age-friendly Primary Health Care Centres Toolkit” [1]. The study found that 81.86% of physical environment properties are matching the recommendation of WHO, while signage matching was 44.6%. The study concluded that most PHC properties have a physical design that met WHO’s recommendations. The two major deviations were accessibility by public transportations and presence of grab bars. Factors that had a significant impact on design were compliance with multiple international and local standards, the availability of private cars, and the availability of wheel chairs. Signage in DHA’s health centers followed a central plan that differed from WHO’s recommendations.
文摘Patient satisfaction is a crucial measure of healthcare quality and plays a vital role in ensuring effective healthcare systems. This study aims to assess the level of patient satisfaction with primary healthcare services in Riyadh, Saudi Arabia, identify social factors affecting satisfaction, and determine the reasons behind dissatisfaction and how to improve satisfaction. The study employed a cross-sectional observational design and included a random sample of 400 patients from primary healthcare centers in Riyadh. Data were collected using an electronic questionnaire and analyzed using SPSS software. The study found that patients were generally satisfied with the primary healthcare services provided in Riyadh, with high levels of satisfaction reported for booking appointments, triage services, and emergency care. However, some aspects of the healthcare experience, such as long waiting times and the physical design of healthcare centers, need improvement. These findings can be used to inform the development of policies and interventions aimed at enhancing healthcare quality in Saudi Arabia.
