Methods: 74 colorectal cancer patients who attended Hospital 960 from January 2021 to January 2022 were retrospectively analyzed. Clinical data of the patients were collected, including gender, age, and histologic type. Immunohistochemical indexes such as Th17 cell level and monocyte/ lymphocyte ratio in the peripheral blood of patients were also collected. The prognosis of patients after treatment, as well as peripheral blood Th17 and MLR levels, were observed and analyzed. Results: After follow-up after treatment, in the final 74 patients, the prognosis was good in 32 patients, accounting for 43.24%, and the prognosis was bad in 42 patients, accounting for 56.76%. There were no significant differences between the average age and tumor diameters of the good prognosis and poor prognosis groups (P > 0.05). However, the TNM staging, intervention taken, differentiation degree, presence of distant metastasis, presence of lymph node metastasis, Th17 level, and MLR level are significantly different between the two groups (P < 0.05). Conclusion: Peripheral blood Th17 and MLR have predictive value for the prognosis of colorectal cancer patients, and high levels of peripheral blood Th17 and MLR imply poor prognosis. The detection of peripheral blood Th17 and MLR levels is simple and convenient and can be used as indicators to provide a reference for the prognostic assessment of colorectal cancer patients.展开更多

Many studies were done to investigate different factors that can affect the success rate. This study was conducted to evaluate if cycle day 3 (CD3) follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratio can be a predictor for the IVF outcome in young sub-fertile females ≤ 35 years with normal baseline FSH. This is a retrospective case control study conducted at the Centre of Fertility and Andrology Care (CFAC) in Egypt where 235 sub-fertile women underwent IVF. Patients were grouped based on CD3 FSH/LH ratio. Group A consisted of ≤35-year-old women with FSH/LH ratio ≤35-year-old women with FSH/LH ratio ≥ 2. The primary outcomes include the fertilization rate, implantation rate and the clinical pregnancy rate. The secondary outcomes include duration and the total dose of gonadotrophin used. We found that, there was no significant difference in the total dose of gonadotropin used during the IVF cycle. Also, there was no significant difference in the number of retrieved and fertilized oocytes and the number of good embryos. Clinical pregnancy rate was the same in both groups. In conclusion, in patients younger than 35 years, CD3 FSH/LH ratio is not a predictor for IVF outcome.展开更多

文摘In Vitro Fertilization (IVF) is the treatment for many causes of infertility. Many studies were done to investigate different factors that can affect the success rate. This study was conducted to evaluate if cycle day 3 (CD3) follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratio can be a predictor for the IVF outcome in young sub-fertile females ≤ 35 years with normal baseline FSH. This is a retrospective case control study conducted at the Centre of Fertility and Andrology Care (CFAC) in Egypt where 235 sub-fertile women underwent IVF. Patients were grouped based on CD3 FSH/LH ratio. Group A consisted of ≤35-year-old women with FSH/LH ratio ≤35-year-old women with FSH/LH ratio ≥ 2. The primary outcomes include the fertilization rate, implantation rate and the clinical pregnancy rate. The secondary outcomes include duration and the total dose of gonadotrophin used. We found that, there was no significant difference in the total dose of gonadotropin used during the IVF cycle. Also, there was no significant difference in the number of retrieved and fertilized oocytes and the number of good embryos. Clinical pregnancy rate was the same in both groups. In conclusion, in patients younger than 35 years, CD3 FSH/LH ratio is not a predictor for IVF outcome.
