They could be syndromic or non-syndromic, with a global incidence of 1:700 per live births. Environmental and genetic factors are thought to play various roles in the aetiology of OFCs. This study seeks to establish the diversity, distribution and pattern of inheritance of OFCs as well as environmental and other risk factors associated with OFCs in a Ghanaian population. A family-based, descriptive cross-sectional study that employed an interview-based survey questionnaire was used to obtain information from 467 families with history of OFCs. We employed chi-square statistics to analyse the data and used graphs to interpret the data. All previously reported subphenotypes of OFCs were observed by the present study. Clinically, about 12% of clefts in the study population were syndromic. The most common syndromic forms observed were Pierre Robin Sequence, cleft-with-club foot abnormalities and Van der Woude Syndrome. Only about 5% of clefts in the study cohort were familial. The study also established that lower level of education of parents, poverty, late antenatal care and dietary folate deficiency are major environmental factors associated with clefts in the Ghanaian population. In conclusion, OFCs are non-randomly distributed in Ghana and folate deficiency could likely be a source of genetic mutations and “epimutations” that cause OFCs, since folate is essential for DNA methylation, replication and repair as well as histone modification.展开更多

Methods： A non-randomized controlled design was used to compare between the acupuncture group and the medication group. The acupuncture group received 8-week acupuncture therapy, and the medication group received budesonide nasal spray with cetirizine tablets for 8 weeks. The clinical symptoms and signs were analyzed before treatment, at 4 and 8 weeks after the start of treatment, and at 12 weeks after the end of treatment. Furthermore, the clinical efficacy and safety indicators were compared between the two groups. Results： A total of 76 participants consisting of 38 in each of the two groups were enrolled. The scores of each clinical symptom and sign, including sneezing, runny nose, stuffy nose, nasal itching, and turbinate edema, and the total scores decreased over time in both groups （all P〈0.05）; and no difference was found in the scores between the two groups （P〉0.05）. There was no statistically significant difference in the effective rates of the acupuncture group at 4 and 8 weeks after the start of treatment as well as at 12-week follow-up compared with those of the medication group （83.3% vs. 91.2%, and 94.4 % vs. 85.3%; and 80.6 % vs. 82.4%, all P〉0.05）. Experimental items including blood routine, urine routine, aspartate transaminase, alanine aminotransferase, urea nitrogen and creatinine were all in the normal reference ranges during the treatment in the acupuncture group. Conclusions： Acupuncture therapy has a comparable effect to the medication treatment on patients with moderate to severe allergic rhinitis, and it is safe with no severe adverse effects.展开更多

Methods: The subjects were female university students living in the Kinki area. A longitudinal survey was conducted on 67 members in the intervention group, who received the health education, and 52 members in the control group, who did not receive the health education. The primary outcome measures were knowledge of PCC and the subscales of the Health Promotion Lifestyle Profile. Surveys were conducted before, after, and six months after the intervention in the intervention group, and an initial survey and survey six months later were conducted in the control group. Cochran’s Q test, Bonferroni’s multiple comparison test, and McNemar’s test were used to analyze the knowledge of PCC data. The Health Awareness, Nutrition, and Stress Management subscales of the Health Promotion Lifestyle Profile were analyzed by paired t-test, and comparisons between the intervention and control groups were performed using the two-way repeated measures analysis of variance. Results: In the intervention group of 67 people, the number of subjects who answered “correct” for five of the nine items concerning knowledge of PCC increased immediately after the health education (P = 0.006) but decreased for five items from immediately after the health education to six months later (P = 0.043). In addition, the number of respondents who answered “correct” for “low birth weight infants and future lifestyle-related diseases” (P = 0.016) increased after six months compared with before the health education. For the 52 subjects in the control group, there was no change in the number of subjects who answered “correct” for eight out of the nine items after six months. There was also no increase in scores for the Health Promotion Lifestyle Profile after six months for either the intervention or control group. Conclusion: Providing health education about PCC using videos and leaflets to adolescent females was shown to enhance the knowledge of PCC immediately after the education.展开更多
