Cartap is among the most popular pesticides that are widely used to boost food production, however, its residues pose a great threat to human health and the environment. We presented simple and effective colorimetric sensor based on aggregation of gold nanoparticles (AuNPs) with appropriate diameter and fluorescent sensor via inner filter effect (IFE) of AuNPs on cadmium telluride quantum dots (CdTe QDs), respectively. Firstly, effect of diameter of AuNPs was investigated and the results indicated that AuNPs with diameter of 13 nm (AuNPs13nm) showed better sensitivity toward cartap. Thus, AuNPs13nm was chosen for colorimetric and fluorescent cartap assay. On one hand, mercaptoacetic acid (MA) was functionalized on AuNPs13nm for the improvement of anti-disturbance ability for discrimination study. A decent linear relationship for cartap was obtained in the range from 1 µM to 50 µM with detection limit of 1.32 µM for colorimetric readout; on the other hand, fluorescent sensor based on AuNPs13nm displayed excellent linear relationship with cartap concentration varying from 20 nM to 100 nM with low detection limit of 4.02 nM. And the above-mentioned sensor showed acceptable anti-disturbance ability for cartap discrimination. These results demonstrated that the sensor as-developed would be a great potential candidate for cartap detection in real application.

Objective: To evaluate the effectiveness of oral contraceptive pill (OCP) as therapy for endometrial hyperplasia (EH) without atypia in reproductive-aged women compared with oral progestin. Methods: A retrospective cohort study was carried out in our reproductive center. Consecutive patients diagnosed with infertility and non-atypical EH identified through electronic database who met inclusion criteria (n=309). Patients were assigned to two treatment groups: OCP (n=216) and oral progestin (n=93); clinical and reproductive outcomes were recorded. Results: Reversal of EH to normal endometrium, clinical pregnancy, live birth and miscarriage rate. Women in OCP group were younger, had higher prevalence of Polycystic Ovary Syndrome and other uterine pathology and longer duration of infertility than women in progestin group. Reversal of EH was observed in 93.52% women on OCP and in 86.02% women on progestin (p=0.032; adjusted odds ratio [aOR]= 2.35; 95% confidence interval [CI]=1.06-5.21) after the initial course of treatment for 2 to 6 months. Cyclic OCP (n=184) resulted in better response to treatment compared to continuous OCP (n=32) (95.11% vs. 84.38%; p=0.039; aOR =3.60; 95% CI =1.12-11.55). Clinical pregnancy rate in OCP group was marginally higher than progestin group (87/208, 41.83% vs. 27/90, 30.00%; p=0.054). Miscarriage (25.29% vs. 29.63%; p=0.654) and live birth rate (31.25% vs. 21.11%; p=0.074) were comparable between the groups. Conclusion: For the first time we demonstrate that OCP is an effective therapy for nonatypical EH and is associated with higher remission rate compared with oral progestin. Reproductive outcomes are reassuring and comparable between the two groups.

Objective: To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. Methods: The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. Results: A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. Conclusion: LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.
