With the development of science and technology worldwide, the blooming of artificial intelligence (AI) and big data has brought new opportunities and challenges to the promotion of the research capacity of professional master's students in oncology. The construction of the new medical education in China aims to cultivate high-level medical talents with comprehensive multidisciplinary skills and innovative abilities to flexibly solve complex problems at the frontier of medicine. In this context, professional master's students in oncology, who are facing problems such as low scientific research output and uneven quality and needing improving scientific research literacy, have been required to develop into compound talents with both clinical and research prowess. To cultivate and promote the research capacity of professional master's students in oncology, the key steps include accelerating the construction of AI education and databases, highlighting the cultivation of their scientific research capacity, implementing and fostering the cultivation of innovative ability and scientific research thinking, piloting joint cultivation models by engineering universities and medical universities, emphasizing the construction of the curriculum and teacher team for oncology, piloting the multidisciplinary mode and COME mode, and establishing a multidisciplinary cooperation network.

To summarize and analyze the clinical data of one case of kidney transplantation in an HIV-positive child with end-stage renal disease (ESRD) in the Department of Transplantation, the People's Hospital of Guangxi Zhuang Autonomous Region, and to explore the safety and efficacy of kidney transplantation in HIV-positive children with ESRD. This pediatric recipient was found to be HIV-positive at birth and underwent kidney transplantation due to ESRD, with good postoperative recovery. During the 2.5-year follow-up, no rejection or rebound in HIV RNA levels was observed. The function of the transplanted kidney was good, and the quality of life was comparable to that of healthy individuals. It suggests that kidney transplantation in HIV-positive children with ESRD is safe and effective under adequate preoperative preparation and close postoperative follow-up.

Objective:To explore the effectiveness of interprofessional cooperative simulation in teaching emergency care for shock patients among intensive care unit (ICU) undergraduate nursing students.Methods:An interprofessional cooperative simulation-based teaching faculty team was established for ICU undergraduate nursing students, and a shock case library was developed. Using convenience sampling, 32 ICU undergraduate nursing students in 2022 were selected as the control group and received conventional simulation-based teaching, with students rotating through roles as nurses, standardized patients, doctors, and family members. In the experimental group, 34 ICU undergraduate nursing students in 2023 and 24 ICU clinical medicine interns were recruited to act as doctors for interprofessional cooperative simulation-based teaching. Each group was divided into subgroups, with each subgroup consisting of 4-5 nursing students. One group completed simulation-based training per month for a total of 8 sessions, with each session lasting 3 hours. The teaching adopted the on-site "tidal ward" in situ simulation, and the scenarios included patient history collection and health assessment, shock emergency care, nursing evaluation, and health education. The differences between the two groups of nursing students were compared in terms of ICU exit theoretical assessment score, objective structured clinical examination skill assessment score, and satisfaction with simulation-based teaching. SPSS 22.0 was used for independent samples t test and Mann-Whitney U test. Results:The experimental group achieved significantly higher scores in theoretical assessment (84.65±8.06), total score of satisfaction with simulation-based teaching (101.00±5.13), and clinical learning and multiprofessional team dimensions (47.32±3.35) compared to the control group ( P<0.001). The experimental group achieved higher scores in objective structured clinical examination skill assessment (81.40±7.22), guiding feedback and reflection (37.50±3.04), and judgmental thinking and clinical reasoning (16.00±2.03) compared to the control group, though the differences were not significant ( P=0.977, 0.668, and 0.636). Conclusions:Interprofessional cooperative simulation enhances the shock patient emergency care abilities and satisfaction with simulation-based teaching for undergraduate nursing students.

Objective To analyze the current situation of dietary diversity and caregiver self-efficacy for complementary feeding among infants and young children aged 6 to 23 months in rural Nanchong city,Sichuan province,and to explore the relationship between dietary diversity and caregiver self-efficacy.Methods Multi-stage randomized cluster sampling method was used to select infants and young children aged 6 to 23 months and their caregivers in rural areas of Nanchong city,Sichuan province as the subjects.A structured questionnaire was designed to collect the basic information of the subjects,dietary diversity,and caregiver self-efficacy for comple-mentary feeding.Multivariate Logistic regression was adopted to analyze the relationship between the dietary diver-sity and caregiver self-efficacy for complementary feeding of infants and young children.Results A total of 770 pairs of infants and young children and their caregivers were included.The minimum pass rate of dietary diversity was 61.56% (474/770)for all the infants and young children and 45.00% (108/240),69.16% (287/415),and 68.70% (79/115)for the infants and young children aged 6 to 11,12 to 17,and 18 to 23 months,respective-ly.The results of regression analysis showed that the caregiver self-efficacy of complementary feeding was a contributing fac-tor for qualified dietary diversity of infants and young children in the case of other confounders being controlled(OR = 1.42,95% CI=1.17-1.73,P<0.001).Conclusion The dietary diversity for infants and young children in rural Nan-chong city,Sichuan province needs to be improved,and caregivers with higher self-efficacy of complementary feeding are more likely to provide diversified complementary feeding for infants and young children.

Objective To investigate the current status of physical activity and depressive symptoms a-mong middle-aged and older adults in Chengdu,Sichuan and explore the relationship between physical activity and depressive symptoms.Methods Multi-stage proportional stratified random sampling was employed to select middle-aged and older adults aged ≥45 years as the participants,and face-to-face interviews were carried out to collect data.Logistic regression was adopted to explore the relationship between physical activity and depressive symptoms in middle-aged and older adults.The trend test was performed for the relationship between different lev-els of physical activity and depressive symptoms.The subgroup analysis and the test for multiplicative interactions were conducted for the relationship between physical activity and depressive symptoms.Results A total of 4376 middle-aged and older adults were included.Among them,14.58％(638/4376),25.98％(1137/4376),and 27.83％(1218/4376)had depressive symptoms,failed to reach the guideline-recommended standards of physical activity,and were at low levels of physical activity,respectively.There was a negative association be-tween reaching guideline-recommended physical activity standard and depressive symptoms in middle-aged and ol-der adults(OR=0.713,95％CI=0.589-0.861,P＜0.001).In addition,moderate levels(OR=0.714,95％CI=0.586-0.871,P=0.001)and high levels of physical activity(OR=0.705,95％CI=0.548-0.906,P=0.006)had negative associations with the presence of depressive symptoms.The trend test revealed that the negative association between physical activity and depressive symptoms in middle-aged and older adults enhanced as the level of physical activity increased(Pfor trend=0.001).The subgroup analysis and the test for multiplicative interactions revealed that neither reaching guideline-recommended physical activity standards or not nor the physi-cal activity level had an interaction with each of the subgroups(all Pfor interaction＞0.05).Conclusions The current status of depressive symptoms among middle-aged and older adults in Chengdu,Sichuan needs to be ameliora-ted.A negative association existed between reaching the guideline-recommended physical activity standard and pres-ence of depressive symptoms,and the negative association enhanced as the physical activity level elevated.

Objective To investigate the effects of different concentrations of morphine in combination with ropivacaine on proliferation,migration,invasion and cell cycle in MDA-MB-231 breast cancer cells.Methods MDA-MB-231 breast cancer cells were inoculated on the culture plate for 24h and randomly divided into 8 groups:Control group(C),ropivacaine 400μg/ml group(R),morphine 3μg/ml group(LM),morphine 30μg/ml group(MM),morphine 300μg/ml group(HM),ropivacaine 400μg/ml group+ morphine 3μg/ml group(R+LM),ropivacaine 400μg/ml+ morphine 30μg/ml group(R+MM),and ropivacaine 400μg/ml+ morphine 300μg/ml group(R+HM).After treaments of MDA-MB-231 breast cancer cells for 24h,these proliferation,migration,invasion and cell cycle were evaluated.Results When using morphine alone,the proliferation inhibitive effect was positively correlated with the concentration of morphine.The proliferation was significantly inhibited by morphine of LM,MM,HM group(P<0.05).When using ropivacaine alone,the proliferation was significantly inhibited(P<0.05).When using morphine combined with ropivacaine,the high concentration morphine group has a synergistic effect with ropivacaine group on proliferation inhibition(P<0.05).When using morphine alone,the migration rate decreases sequentially with the increase of morphine concentration.The migration rate was significantly inhibited by morphine of LM,MM,HM group(P<0.05).When using ropivacaine alone,the migration rate was inhibited(P<0.05).When using morphine combined with ropivacaine,the low and medium concentration morphine group have a synergistic effect with ropivacaine group on migration rate(P<0.05).When using morphine alone,the number of cell invasion was decreased with the concentration of morphine increasing(P<0.05).The MM and HM groups inhibited cell invasion ability.When using ropivacaine alone,the invasiveness of cells was also inhibited(P<0.05).When using morphine combined with ropivacaine,the medium and high concentration morphine groups have a synergistic effect with ropivacaine group on inhibiting cell invasion ability(P<0.05).When using morphine alone,the cell cycle progression was inhibited into G2/M Phase(P<0.05).When using ropivacaine alone,the cell cycle progression was inhibited into G2/M phase(P<0.05).The combination of low concentration morphine and ropivacaine has synergistic effect on arresting at G0/G1 and S phase(P<0.05).Conclusion Morphine combined with ropivacaine inhibits the Proliferation,migration and invasion of MDA-MB-231 breast cancer cells in a dose-dependent manner.

ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis （ONFH， syndrome of liver and kidney deficiency） and its influences on bone metabolism indexes： N-terminal propeptide （PINP） and β-collagen degradation product （β-CTX）. MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method， with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally， while the control group received Xianlinggubao Capsules orally， with a treatment cycle of 6 months. The visual analogue scale （VAS） score， Harris score， Association Research Circulation Osseous （ARCO） staging， imaging changes， quantitative scores of TCM symptoms， and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% （26/31）， which was higher than that （68.75%， 22/32） in the control group （Z=-2.096， P<0.05）. After treatment， the single and total scores of TCM symptoms， VAS score， and β-CTX level decreased in the two groups （P<0.05）. Moreover， the decreases in the scores of hip pain， lower limb mobility， soreness of waist and knees， and lower limb flaccidity， total score of TCM symptoms， VAS score， and β-CTX level in the experimental were larger than those in the control group （P<0.05）. After treatment， the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment （P<0.05）， and the increases were more obvious in the experimental group than in the control group （P<0.05）. No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH， increase PINP， and decrease β-CTX. No obvious side effect appears during the clinical observation period， which shows that Bushen Huoxue prescription has good safety.
