Objective:To explore the symptom perception and coping experiences of patients with low anterior resection syndrome (LARS) after anus-preserving surgery for rectal cancer.Methods:This study adopted the phenomenological research method in qualitative research. From October 2022 to January 2023, purposive sampling was used to select 15 postoperative LARS patients with rectal cancer who underwent anus-preserving surgery and underwent outpatient follow-up or hospitalization at Henan Cancer Hospital as the research subject for semi-structured in-depth interviews. Colaizzi 7-step analysis method was used to analyze, summarize, and extract themes from interview data.Results:Four themes were extracted, including attitudes and emotional responses towards symptoms, daily activities influenced by symptoms, coping status with symptom management strategies, and the need for multidimensional support for symptoms.Conclusions:LARS patients after anus-preserving surgery for rectal cancer have many discomfort symptoms and are eager to receive support and assistance. Medical and nursing staff should pay attention to the complexity of patient symptom management and promptly conduct effective symptom assessment and intervention, providing patient-centered comprehensive supportive nursing, and improving their quality of life.

Purpose To investigate the expression of TRPS1 in synovial sarcoma(SS)and its significance.Methods Twenty-one cases of synovial sarcoma diagnosed by SS1 8(18q11)(SYT)fluorescence in situ hybridization(FISH)or SS18-SSX immunohistochemistry were collected.The expression of TRPS1 was detected by immunohistochemistry EnVision two-step staining,and the relevant literature was reviewed.Results There were 21 cases of synovial sarcoma,including 9 females and 12 males,aged 17-79 years,with a median age of 50 years and an average age of 47.1 years.The tumors occurred in the lung(3 cases),legs(3 cases),kidney(3 cases),feet(2 cases),psoas major muscle(2 cases),rectum(1 case),tho-racic cavity(1 case),ankle canal(1 case),inguinal area(1 case),knee(1 case),palm(1 case),nasal cavity(1 case),and forearm(1 case).The maximum diameter of the tumor was 1.2-13 cm.Grossly,the tumor section was grayish-white,grayish-yellowish solid,and the lesion with hemorrhage was dark red.Microscopically,there were monophasic fibrous SS(16/21,76.2％),poorly differential SS(small cell)(3/21,14.3％),and biphasic SS(2/21,9.5％).Immunophenotypi-cally,tumor cells expressed SS18-SSX(18/18,100％),TLE1(12/12,100％),BCL2(18/18,100％),partially expressed EMA(10/16,62.5％),CK(12/18,66.7％),CD99(4/10,40.0％),SMA(3/16,18.6％),S-100(3/19,15.8％),and desmin(0/21).The proliferation index of Ki67 ranged from 3％-80％,with an average of 39.9％.FISH test showed that all 11 cases were positive for SS18(18q11)split-ting.All 21 cases of SS expressed TRPS1 to varying degrees and intensities(21/21,100％),of which 19 cases(19/21,90.5％)had a positive range of＞50％.There were 19 cases(19/21,90.5％)with a positive intensity of 2+or above.All the 21 patients underwent surgical resection of the tumor,and 20 patients received follow-up visits.3 patients treated with postop-erative combination of radiotherapy and chemotherapy,18 pa-tients treated with postoperative chemotherapy,and 7 patients showed different degrees of recurrence or metastasis,and 9 pa-tients who received follow-up visits died(45％,9/20).Con-clusion Although TRPS1 is regarded as a highly sensitive and specific marker of breast tumor origin,it is also highly expressed in synovial sarcoma,and it is necessary to be vigilant at its pit-falls in the pathological diagnosis.

Objective:To investigate the relationship between dietary vitamin A intake and its sources in the first trimester and gestational diabetes mellitus (GDM).Methods:A prospective study was conducted to select women at 6-14 weeks of gestation in an obstetric clinic of a maternal and child health care medical institution in Chengdu in 2017. The types and quantities of food during the first trimester were collected by 3-day 24-hour dietary recalls. Dietary vitamin A intake was calculated based on the Chinese Food Composition Table (2018), and it was divided into animal and plant vitamin A intakes according to its food sources. An oral glucose tolerance test was performed at 24-28 weeks of gestation to diagnose GDM according to the Chinese guidelines for diagnosis and treatment of gestational diabetes mellitus (2014). According to the estimated average requirement (EAR) and recommended nutrient intake (RNI), dietary vitamin A intake was divided into low-level group (RNI). Animal and plant vitamin A intakes were divided into four groups (Q1-Q4) according to the quartile method, respectively. The association between dietary vitamin A intake, its different sources of vitamin A intake and GDM in the first trimester was analyzed by log-binomial regression models.Results:A total of 1 298 valid samples were finally included. The average dietary vitamin A intake, animal and plant vitamin A intakes in the first trimester were 341.1 (227.8-501.0) μgRAE/d, 139.3 (69.6-195.3) μgRAE/d and 184.2 (99.4-301.1) μgRAE/d, respectively. After adjusting for confounding factors, log-binomial regression analysis showed that the risk of GDM in high-level group of dietary vitamin A intake was lower than that in low-level group [ RR (95% CI):0.53 (0.36-0.80)]. Pregnant women in the highest quartile of animal vitamin A intake had a lower risk of GDM than those in the lowest quartile [ RR (95% CI):0.66 (0.47-0.95)]. No relationship between plant vitamin A intake and GDM was found. Conclusion:Dietary vitamin A intake in the first trimester is associated with the occurrence of GDM, and higher intake than RNI may reduce the risk of GDM. Higher vitamin A intake from animal-derived food is associated with decreased risk of GDM.
