Objective:To investigate the diagnostic value of contrast-enhanced ultrasound（CEUS）in solid pseudopapillary tumor of pancreas（SPTP），summarize the CEUS characteristics of SPTP，and to compare its CEUS enhancement with contrast-enhanced computed tomography（CECT）.Methods:In this retrospective study，baseline characteristics，basic ultrasound and CEUS images，CECT images of 70 patients diagnosed as SPTP from January 2009 to August 2023 were collected. Images were analyzed for extraction of key features and diagnostic accuracies of both CEUS and CECT were calculated. The relationships between ultrasound features and lesion size of SPTP were analyzed by Point-Biserial correlation analysis and Student t test. The diagnostic accuracy was compared by Mann-Whitney U test. Results:Iso-enhancement（55.7%，39/70）was commonly appeared in the early phase of CEUS for SPTP，while hypo-enhancement（74.3%，52/70）was the most common in the late phase. And the most common enhancement pattern was iso-hypo enhancement（41.4%，29/70）. Lesion membrane enhancement（47.1%，33/70），intralesional compartmentalization（28.6%，20/70），and intralesional vessels（25.7%，18/70）were the 3 typical signs found in CEUS for SPTP，which were correlated with lesion size（ P＜0.001）. Differences were found between the enhancement pattern of SPTP in CEUS and CECT，in which the most common enhancement patterns were hypo-hypo enhancement（41.4%，24/58）and iso-iso enhancement（29.3%，17/58）along with progressive enhancement. The diagnostic accuracies of CEUS and CECT were 71.4% and 74.1% respectively without statistically significant difference（ P=0.733）. Conclusions:CEUS shows high application value in the diagnosis of SPTP，and the accuracy of CEUS is comparable to that of CECT.

Objective:To explore the effects of Nie Ji tuina combined with acupoint massage on cellular immune function in children with recurrent respiratory tract infection (RRTI).Methods:Randomized controlled trial. A total of 96 children in the hospital were enrolled as the observation objects between June 2020 and October 2021. According to random number table method, they were divided into control group (acupoint massage) and observation group (Nie Ji tuina combined with acupoint massage), 48 in each group. All were treated for 8 weeks and followed up for 8 months. TCM syndromes were scored before and after treatment. The levels of CD4 +, CD8 + and CD4 +/CD8 + ratio in peripheral blood were detected by flow cytometry. The frequency of RRTI attacks during follow-up was observed, and the clinical curative effect was evaluated. Results:There was no significant difference in total response rate between observation group and control group [93.75% (45/48) vs. 81.25% (39/48); χ2=3.43, P=0.064]. After treatment, scores of TCM syndromes (cough, fatigue, shortness of breath and laziness to speak, spontaneous sweating) were significantly lower in observation group than control group ( t=3.95, 9.64, 7.68, 8.34, P<0.01). After treatment, levels of CD4 + and CD4 +/CD8 + were increased ( P<0.01), while CD8 + level was decreased in both groups ( P<0.01), but there was no significant difference between the two groups ( P>0.05). During follow-up, observation group times of recurrence attacks were fewer than those in the control group ( t=10.60, P<0.01). Conclusion:Nie Ji tuina combined with acupoint massage can improve disease resistance ability and reduce RRTI frequency in children.

Objective:To investigate the effect of peer support-based narrative therapy on postoperative self-image and stigma of patients with head and neck cancer, to provide reference for clinical nursing.Methods:A total of 78 head and neck cancer patients from August 2018 to August 2020 in Fudan University Shanghai Cancer Center were divided into experimental group and control group by random digits table method, each group were 39 cases. The control group was given conventional nursing, while the experimental group implemented support-based narrative therapy on the basis of routine nursing. The intervention time was 4 weeks. The self-image and stigma of the two groups before and after intervention were assessed by Body Image Scale (BIS) and Social Impact Scale (SIS), respectively.Results:Finally, 37 cases were included in the experimental group and 38 cases in the control group.

Isolated cortical vein thrombosis (ICoVT) is very rare and its clinical symptoms lack specificity.Unlike cerebral venous sinus thrombosis,ICoVT rarely presents increased intracranial pressure and optic disc edema.Imaging examination,especially MRI examination,is very important for the diagnosis of this disease.T2 *-weighted gradient echo sequence and susceptibility-weighted imaging contribute to the early diagnosis of the disease.This article reviews the clinical symptoms,diagnosis,and treatment of ICoVT.

Development of ovarian cancer involves the co-evolution of neoplastic cells together with the adjacent microenvironment. Steps of malignant progression including primary tumor outgrowth, therapeutic resistance, and distant metastasis are not determined solely by genetic alterations in ovarian cancer cells, but considerably shaped by the fitness advantage conferred by benign components in the ovarian stroma. As the dynamic cancer topography varies drastically during disease progression, heterologous cell types within the tumor microenvironment (TME) can actively determine the pathological track of ovarian cancer. Resembling many other solid tumor types, ovarian malignancy is nurtured by a TME whose dark side may have been overlooked, rather than overestimated. Further, harnessing breakthrough and targeting cures in human ovarian cancer requires insightful understanding of the merits and drawbacks of current treatment modalities, which mainly target transformed cells. Thus, designing novel and precise strategies that both eliminate cancer cells and manipulate the TME is increasingly recognized as a rational avenue to improve therapeutic outcome and prevent disease deterioration of ovarian cancer patients.
