Objective:To design two kinds of intensity modulated radiotherapy (IMRT) plans with different radiation field distributions,and to compare the dose differences of that at the dose of target region and organs at risk (OAR) for middle and lower esophageal cancer,so as to provide a reference for the design of IMRT plan. Methods:The data of 17 patients with middle and lower esophageal cancer who received IMRT at Shangluo Central Hospital from November 2022 to May 2023 were retrospectively analyzed. IMRT plans with different radiation fields for Plan 1 and Plan 2 were designed for each patient. The angles of radiation field for Plan 1 were 0°,80°,120°,160° and 200°,and those for Plan 2 were 30°,130°,180°,230° and 330°,respectively. The prescribed dose to the planning target volume (PTV) was 60 Gy/30 F. The differences in dosimetric parameters between the two plans were compared. Results:There were no statistically significant differences in the dose parameters of 2％,98％,50％ target dose (D2％,D98％,D50％),homogeneity index (HI),conformity index (CI) and monitor unit between the two groups (P>0.05). There were no significant differences in V5 of dual lungs,the mean dose (Dmean) of heart,and the maximum dose (Dmax) of spinal-cord between two groups (P>0.05). The volume percentage (V10,V20,V30) of dual lungs received radiation doses of 10,20 and 30 Gy,and the mean dose (Vmean) of lung in the Plan1 group reduced respectively 7.44％,21.16％,10.09％ and 5.31％ than those in the Plan2 group,and the differences of them were statistically significant (t=-5.845,-7.729,-2.247,-3.960,P<0.05). Heart V10 and V20 in the Plan1 group decreased respectively by 7.23％ and 5.78％,with statistical significance (t=-4.376,-3.523,P<0.01),while V30 and V40 of Plan 1 increased respectively by 2.7％ and 4.92％,without statistical significance (P>0.05). There was no significant difference in heart Dmean between the Plan1 group and the Plan2 group (P>0.05). Conclusion:Both two methods of distribution field can meet the clinical requirements,and Plan1 has more advantages in protecting organs at risk under the premise of meeting the requirements of target region.

Objective:To explore the effect of self-compassion-based writing on prosocial behavior in college students with different self-construals.Methods:A total of 182 college students were recruited,and the Self-Con-structional Scales were used to determine the self-construal types(independent or interdependent).Participants were then assigned to either a self-compassion-based writing group(n=91)or a non-self-compassion daily writing group(n=91)and completed writing tasks according to the respective instructions.Prosocial behavior was evaluated with the Prosocial Tendencies Measure(PTM),situational judgment tests,and donation amounts.Results:The evaluation results from the PTM showed that prosocial behavior was significantly higher in individuals with interdependent self-construal compared to those with independent self-construal(P＜0.001),the main effect of the group type was not statistically significant(P＞0.05).The evaluation results from situational judgment tests showed that prosocial behavior was significantly higher in individuals with interdependent self-construal compared to those with independ-ent self-construal(P＜0.001),the self-compassion-based writing group demonstrated significantly more prosocial behavior than the non-self-compassion daily writing group(P＜0.05).The evaluation results from donation a-mounts showed that the main effect of self-construal type was not statistically significant(P＞0.05),the self-com-passion-based writing group demonstrated significantly more prosocial behavior than the non-self-compassion daily writing group(P＜0.05).Conclusion:Compared to daily writing,self-compassion-based writing could effectively increase prosocial behavior in college students,regardless of their self-construal type.

This study analyzed the epidemiological characteristics of imported malaria in Yunnan Province from 2020 to 2023,to provide scientific evidence for formulating measures to decrease imported malaria and prevent re-establishment of malaria transmission.Malaria data reported by the China Disease Prevention and Control Information System were analyzed to determine parasite species;sources of infection;temporal,spatial,and population distributions;and importation routes.A total of 828 malaria cases were reported in the province.Plasmodium vivax and Plasmodium falciparum accounted for 89.98％and 8.33％of cases,respectively.A total of 47.58％of cases were imported from Myanmar,and all P.falciparum malaria ca-ses were from Africa.Thirteen(81.25％)prefectures or municipalities reported malaria,among which Dehong,Baoshan,Kunming,and Lincang reported 94.32％of cases.A total of 52.54％of cases were in young men.The proportion of cross-bor-der personnel flow,land input,and aircraft input were 88.89％and 11.11％respectively.A total of 98.19％of patients sought medical care within 7 days after fever onset,and 82.85％initiated diagnosis for malaria,and 84.90％of diagnoses were con-firmed by health facilities at or below the county level.Imported malaria is a major challenge in preventing re-establishment of transmission in Yunnan.Most imported cases involved cross-border malaria transmission of mainly Plasmodium vivax between China and Myanmar.To achieve malaria elimination,vigilance of health staff in malaria diagnosis and treatment should be pro-moted,and intensive malaria health education should be provided to people traveling to malaria endemic territories,to enable individual protection,and timely diagnosis and treatment after return from endemic countries.

Cancer is the main cause of death,and drug therapy has greatly improved the effectiveness of anti-tumor treatment.However,there are problems such as high adverse reactions and the risk of developing drug resistance after long-term use.There is an urgent need to seek new drug targets.Human antigen R(HuR),as an RNA binding protein,promotes the whole process of tumor occurrence,development and metastasis through post transcriptional regulation of mRNA stability,and HuR is general-ly highly expressed in tumor tissue,making it a new target for an-ti-tumor therapy and a standard for prognosis evaluation.Tradi-tional Chinese medicine formulas and their various chemical components can inhibit tumor proliferation,induce tumor cell ap-optosis,inhibit angiogenesis,suppress immune escape,and re-verse tumor drug resistance by regulating HuR activity.This re-view summarizes the importance of HuR in regulation of tumor progression,as well as analyzes the mechanisms of the antitumor effects through active ingredients of Chinese medicine with the regulation of HuR.It is expected to provide new ideas for tumor therapy and guidance for the development of HuR-targeted anti-tumor drugs.

Objective To explore the relationship between insulin resistance and idiopathic central precocious puberty(ICPP)in girls and the diagnostic value of insulin resistance.Methods Clinical data of 245 girls aged 4 to 7.5 years with low luteinizing hormone(LH)levels(0.2-0.83 IU/L),normal body weight(body mass index standard deviation score between-2 and+2),and early breast development who visited the Department of Pediatric Endocrinology,Henan Provincial Maternal and Child Health Hospital from January 2022 to March 2025 were retrospectively analyzed.According to the Expert Consensus on the Diagnosis and Treatment of Central Precocious Puberty(2022),patients were assigned to an ICPP group(n=123)or a control group(n=122).Correlations between the homeostasis model assessment of insulin resistance(HOMA-IR)and selected indices were assessed.Multivariable logistic regression was used to evaluate the association between HOMA-IR and ICPP,and the diagnostic performance of various indices for ICPP was evaluated.Results HOMA-IR was higher in the ICPP group than in the control group(P<0.001)and was positively correlated with LH peak(rs=0.467,P<0.05)and the LH peak/FSH peak ratio(rs=0.444,P<0.05).The multivariable logistic regression model including age,BMI,and basal LH showed that HOMA-IR was closely associated with ICPP(OR=2.756,95%CI:1.940-3.913).Receiver operating characteristic curve analysis showed that the areas under the curve for basal LH,HOMA-IR,and their combination in diagnosing ICPP were 0.735,0.735,and 0.805,respectively(P<0.05),and the combined model had a greater area under the curve than either basal LH or HOMA-IR alone(both P<0.05).Conclusions HOMA-IR is closely associated with ICPP in girls with low LH and normal body weight,and combining HOMA-IR with basal LH improves early identification and diagnostic efficiency in this population.
