【摘要】 目的 探讨儿童弱视治疗效果与疗程的关系。 方法 对2002年5月-2007年5月收治的25例弱视患儿进行戴镜、遮盖、红光闪烁及精细作业训练。3个月复查一次，12个月重新验光，随访12~60个月。 结果 25例弱视患儿经12~60个月随访，25例患儿均治愈，治愈疗程最少3个月，最长达60个月，平均24个月。 结论 儿童弱视只要早期发现，在12岁之前进行干预，早期治疗均可获得治愈。【Abstract】 Objective To discuss the relationship between the effect and duration of the treatment for children amblyopia. Methods Patients diagnosed as amblyopia were administered wearing glasses, occlusion, flashing red, and fine training from May 2002 to May 2007. Reexamination was done 3 months later after the treatment, and the refraction examination was done after 12 months. The follow-up time was from 12 to 60 months. Results The results showed that all of the 25 amblyopic children were cured. The treatment duration was from three months to 50 months with an average of 24 months. Conclusion As long as the amblyopia is detected at the early stage and treated before age 12, all the children can be cured.
Objective To investigate the proportions of CD4+ T cells, CD8+ T cells, and mutant of p53 gene in the microenvironment of breast infiltrating ductal carcinoma, and to explore its’ correlation with prognosis of breast infiltrating ductal carcinoma. Methods Eighty-five cases of breast infiltrating ductal carcinoma were collected who underwent surgery in the 371st Central Hospital of Peoples’ Liberation Army from 2010 to 2012, and then detected the proportion of CD4+ T cells and CD8+ T cells, ratio of CD4+ T cells to CD8+ T cells, and mutant of p53 gene in the cancer tissues with immunohistochemistry. Comparison between the sentinel lymph node metastasis group and non-sentinel lymph node metastasis group, mutant of p53 gene group and non-mutant of p53 gene group on the proportions of CD4+ T cells, CD8+ T cells, and ratio of CD4+ T cells to CD8+ T cells were performed, as well as the relationship between proportion of CD8+ T cells/mutant of p53 gene and prognosis of breast infiltrating ductal carcinoma. Results ① The relationship between proportion of CD4+ T cells/proportion of CD8+ T cells/ratio of CD4+ T cells to CD8+ T cells and situation of sentinel lymph node metastasis: at cluster, compared with the sentinel lymph node metastasis group, the proportion of CD8+ T cells was lower in the non-sentinel lymph node metastasis group (P<0.05), but there was no significant difference on the proportion of CD4+ T cells and ratio of CD4+ T cells to CD8+ T cells (P>0.05); at stroma, compared with the sentinel lymph node metastasis group, the proportions of CD4+ T cells and CD8+ T cells were lower, but the ratio of CD4+ T cells to CD8+ T cells was higher in the non-sentinel lymph node metastasis group (P<0.05). ② The relationship between proportion of CD4+ T cells/proportion of CD8+ T cells/ratio of CD4+ T cells to CD8+ T cells and mutant of p53 gene: both at the cluster and stroma, compared with the mutant of p53 gene group, the proportions of CD4+ T cells and CD8+ T cells were lower, but the ratio of CD4+ T cells to CD8+ T cells was higher in the non-mutant of p53 gene group (P<0.05). ③ The relationship between proportion of CD8+ T cells/mutant of p53 gene and prognosis of breast infiltrating ductal carcinoma: the prognosis was worse in patients with high degree of infiltration of CD8+ T cells and mutant of p53 gene than those patients with low degree of infiltration of CD8+ T cells and non-mutant of p53 gene (P<0.05). Conclusions The proportions of CD4+ T cells and CD8+ T cells, and ratio of CD4+ T cells to CD8+ T cells are associated with the situation of sentinel lymph node metastasis and mutant of p53 gene, and the degree of infiltration of CD8+ T cells and mutant of p53 gene are associated with the prognosis of breast infiltrating ductal carcinoma.
Objective To explore the research progress of the multimodal clinical support system (CSS). Methods With recognized development and operation of the multi-model CSS, and compared to the traditional CSS, to explore the research progress of the multimodal CSS. Results Based on the realization of the concept, purpose and characteristics of the multimodal CSS, it has been known that the international research progress of the multimodal CSS. Conclusion The developing and evolving of the CSS model have offered a new assist to the multi-disciplinary treatment model, and have enhanced the improving system associated with the practice of evidence-based medicine. However, the application of clinical support system program (CSSP) in our country still needs more research.
ObjectiveTo systematically review the efficacy of acellular dermal matrix (ADM) and subepithelial connective tissue flap (sCTG) on patients with gingival recession (GR).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) about the efficacy of ADM and sCTG on patients with GR from inception to August 11st, 2019. Two reviewers indepeudently screened literature, extracted data and assessed the risk of bias of included studies, and then meta-analysis was performed by using RevMan 5.3 software and Stata 12.1 software.ResultsA total of 9 RCTs were included. The results of meta-analysis showed that: there were no significant differences in probing depth (PD) (MD3m=−0.04, 95%CI −0.18 to 0.11, P=0.63; MD6m=−0.01, 95%CI −0.13 to 0.12, P=0.90) and GR degree (MD3m=−0.10, 95%CI −0.37 to 0.18, P=0.48; MD6m=−0.02, 95%CI −0.33 to 0.29, P=0.89) in 3 and 6 months after operative between two groups. But the clinical attachment loss (CAL) in 3 months after operation (MD=0.33, 95%CI 0.00 to 0.66, P=0.05) and width of keratinized tissue (KTW) in 6 months after operation (MD=−0.48, 95%CI −0.76 to −0.20, P=0.000 7) of sCTG group were superior to ADM group, the differences were statistically significant.ConclusionCurrent evidence shows that there are no differences in PD and GR degree in 3 months and 6 months after operation between ADM and sCTG group. But the CAL in 3 months after operation and KTW in 6 months after operation of sCTG group is superior to ADM group. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusion.
