Objective:To investigate the clinical characteristics,pathological features,treatment,and prognosis of clear cell adenocarcinoma of cervix(CCAC).Methods:Clinical data of 72 CCAC patients treated at Jiangxi Maternal and Child Health Hospital from January 1,1999,to June 20,2024,were retrospectively analyzed.Results:The median age at diagnosis was 50 years.Of the patients,19 were classified as early-stage(IB1,IB2,IIA1),51 as mid-advanced stage(IB3,IIA2-IVB),and 2 were unstaged.Among 38 patients,elevated cancer Antigen 125(CA125)levels were observed in19(50.0%).Abnormal thin-layer liquid-based cytology(TCT)results were de-tected in 14 of 20 patients(70.0%),and human papillomavirus(HPV)positivity was identified in 20 of 45 patients(44.5%).Immunohistochemical analysis revealed hepatocyte nuclear factor-1β(HNF-1β)positivity in 95.2%and paired box gene 8(PAX-8)positivity in 91.3%.Among 32 patients undergoing primary surgery,postoperative pa-thology confirmed pelvic lymph node metastasis in 5(15.6%),lymphovascular and stromal invasion in 9(28.1%),with no ovarian metastasis observed.With a median follow-up of 45 months,the5-year overall survival(OS)rate was 51.4%,with early-stage and mid-advanced stage OS rates of 57.9%and 47.1%,respectively.The 5-year OS rate for surgically managed patients was 52.8%,while preoperative neoadjuvant chemotherapy(9 cases)yielded a 5-year OS of 33.3%.Among38 patients treated primarily with radiotherapy and/or chemotherapy,the5-year OS was 47.1%,with 5 patients undergoing central lesion resection achieving an 80.0%5-year OS.Conclusions:CCAC predominantly affects middle-aged and elderly women,with advanced-stage presentations being common.HPV,TCT,and CA125 testing hold diagnostic value for CCAC.Patients with early-stage CCAC undergoing surgical treatment demonstrated a relatively favorable survival rate;however,individualized assessment remains essential.Neoadjuvant chemotherapy administered prior to surgery may have limited efficacy in improving patient prognosis.For selected patients completing radiotherapy and/or chemotherapy,central lesion resection may potentially im-prove prognosis,although further well-designed studies are required to validate this finding.

This paper reviews the currently research on competency of practitioners in the field of nutrition and food hygiene at home and abroad. Through literature review, it's found that the there are few researches on competency in China at present. Furthermore, compared with foreign countries, there are several issues in China, such as the methods and index system setting. However, due to different national conditions, there are significant differences in the demand for nutrition and food hygiene practitioners, related disciplines and characteristics between China and abroad. Therefore, when drawing lessons from foreign models, we should appropriately make adjustments according to China's national conditions. This review will provide references for further research on establishing a set of scientific and standardized competency evaluation indexes for practitioners in the field of nutrition and food hygiene with Chinese characteristics.

Objective To explore the value of endocervical curettage (ECC) in the detection of high-grade cervical squamous intraepithelial lesion (HSIL). Methods We retrospectively analyzed the clinical features and colposcopical characteristics of 678 female patients with complete clinical data. Results Among 678 cases, 391 cases were confirmed by cervical biopsy only and 7 cases by ECC only (57.67% vs. 1.03%, P < 0.001). ECC checked out 287 HSIL patients (42.33%, including cervical biopsy positive and negative cases) and cervical biopsy checked out 671 HSIL cases (98.97%, including ECC positive and negative cases). There were 68 positive ECC cases in the conversion area of Type 1+Type 2 and 247 positive ECC cases in the conversion area of Type 3(33.33% vs. 52.11%, P < 0.001). The positive rates of ECC in patients≥45 years old and < 45 years old were 145 and 170, respectively (55.13% vs. 40.96%, P < 0.001). Conclusion The cervical biopsy plays a dominant role in the detection of HSIL, and ECC can only be used as a supplement to it. Female patients older than 45 years or with Type 3 transformation zone examined by colposcopy should be concerned with cervical lesions.

Objective To investigate the risk factors for ovarian metastasis and the possibility of ovarian preservation in patients with endometrial carcinoma.Methods The clinicopathological features of endometrial carcinoma patients who were diagnosed and treated initially with a surgical staging procedure from Jan 1997 to Dec 2006 in our hospital were retrospectively reviewed.Results Of the 638 cases reviewed,36(5.6%,36/638)had ovarian metastasis.Univariate analysis revealed that histological type and grade,myometrial invasion,positive peritoneal fluid cytology,pelvic lymph node metastasis,invasion of parauterine,para-aortic node metastasis and invasion of uterine serosa were significantly associated with ovarian metastasis(P＜0.05);while age,lymph-vascular invasion and cervical invasion wen not significantly associated with ovarian metastasis(P＞0.05). Factors predictive of ovarian metastasis by multivariate analysis were ranked as follows according to risk intensity:pelvic lymph node metastasis,positive peritoneal cytology,and histological grade.Conclusion In young patients with grode 1 endometrioid carcinoma,with no pelvic lymph node metastasis,no para-aortic lymph node metastasis,no myometrial invasion and with negative peritoneal fluid cytology,ovarian preservation could be considered.
