Objective:To analyze the clinicopathological features of giant ovarian masses(mean diameter≥10 cm)and analyze the clinical characteristics of patients in different age groups.Methods:The clinicopathological characteristics of 311 patients diagnosed with giant ovarian masses by surgery at Nanjing Drum Tower Hospital,Affiliated Hospital of Medical School,Nanjing University from January 2014 to December 2022 were retrospectively analyzed.Patients were further stratified by age and mass size to compare the differences of clinical and patho-logical features among different age groups and different mass diameter groups.Results:①The median age of thepatients were 44(24,60)years old.The first symptoms were as follows:ovarian mass discovered during physi-cal examination,abdominal pain,bloating,conscious abdominal distension,and symptoms of compression.②The surgical methods were as follows:unilateral oophorectomy(30.5％,95/311),ovarian cystectomy(28.9％,90/311),tumor staging or cytoreductive surgery(28.0％,87/311),total hysterectomy with bilateral adnexectomy(12.5％,39/311).③The pathological types were benign(49.5％,154/311),malignant(31.8％,99/311)and borderline(18.7％,58/311).④ Patients complained abdominal distension in＜20 years old group were signifi-cantly higher than the other two groups(P＜0.05).The ovarian resection rate in the＞50-year-old group was higher than that of the other two groups(P＜0.05),and the rate of unilateral ovarian resection in the＜20-year-old group was still as high as 30.1％(15/49).⑤ The size of the mass correlated with the duration of the disease.When the disease course was between 1 to 6 months,the mass diameter line＞30 cm was the most common(P＜0.05).The incidence of borderline tumors in the＞30 cm group was significantly higher than that in the other two groups,and the difference was statistically significant(P＜0.05).Conclusions:Ovarian mucinous and mucinous borderline tumors are the most common types of giant adnexal masses.The size of the mass tends to increase with the prolongation of the disease course.The incidence of borderline tumors increases with the in-crease of mass.Health education for young people should be strengthened.When abdominal pain,abdominal bloating,especially lower abdominal distension occurs,they should seek medical treatment in time to avoid adnex-ectomy due to borderline tumors.

Objective:To construct an evaluation framework with detailed indices for demonstration units (wards) of enteral nutrition nursing, in order to improve the competence of nurses in enteral nutrition nursing and inform the specialized development of enteral nutrition demonstration units (wards).Method:On the basis of literature review and expert discussion, a preliminary draft was developed, and the Delphi expert consultation method was used to conduct two rounds of consultation with 15 clinical experts in the field of enteral nutrition nursing from 15 tertiary hospitals.Results:The effective response rates of questionnaires in two rounds of consultations were both 100%. The first round of expert consultation showed an authority coefficient of 0.90 and a coefficient of variation of 0 to 0.167, while the second round showed an authority coefficient of 0.93 and a coefficient of variation of 0 to 0.113. The Kendall harmony coefficients were 0.338 and 0.368, respectively. Finally, the evaluation framework with detailed indices for the demonstration unit (ward) of enteral nutrition nursing was formed, which consisted of 3 primary indicators, 16 secondary indicators, 54 tertiary indicators, and 62 detailed items.Conclusions:The evaluation framework we developed for the demonstration unit of enteral nutrition nursing follows the diagnosis and treatment process of enteral nutrition management for inpatients, including the triad of structure, process, and outcome. The framework is objective and practical, and can inform the daily practice of enteral nutrition nursing demonstration units (wards) and the development of enteral nutrition nursing specialties.

Objective:To understand the nutritional nursing competence in the enteral nutrition demonstration wards at this stage, so as to inform subsequent training plan.Methods:From September to October in 2023, nurses from 287 institutions involved in the enteral nutrition demonstration ward construction project were selected using convenience sampling. Questionnaires on general characteristics and self-assessment scale on nutrition nursing competence were used for online survey. The status quo and influencing factors of nutrition nursing competence in included institutions were analyzed.Results:A total of 5 409 valid questionnaires were collected, with a response rate of 62.63%. The total score of nutrition nursing competence was 74.74±16.11, with the least subtotals in the domain of nutrtion knowledge. Multiple linear regression showed that influencing factors of nutrition nursing competence includes years of working, department, registered dietitian or not, nutrition management specialist or not, completion of the curriculum in enteral nutrition demonstration ward construction project, and training/supervision arranged by their department concerning nutrtion nursing and relevant evaluation criteria ( P<0.05). Conclusions:The nutritional nursing competence of clinical nurses in the wards involved in enteral nutrition demonstration ward construction project still needs to be improved. Seniors should take into consideration the varying nutritional nursing competence among junior nurses and nurses from different departments, and strengthen the training on nutrition knowledge. It should be encouraged for nurses to actively participate in nutritionist training. Actions including enhancing nutrition specialist training, establishing the multidisciplinary collaborative nutrition care team and conducting regular supervision and assessment should be implemented in the future, to improve the nutritional nursing competence among nurses.

The skin manifestations of monoclonal(M)-proteinemia are rare and present in patients with monoclonal gammopathy of undetermined significance (MGUS), smoldering plasma cell myeloma (SMM) and multiple myeloma (MM). In this study, we reported 4 cases with M-proteinemia-related rare skin lesions, including pyoderma gangrenosum (PG), erythema elevatum diutinum (EED), cutis laxa (CL) and lichen myxedematosus(LM). These skin lesions are specific, where the potential mechanism was immune-mediated paraneoplastic syndrome rather than direct plasma cell infiltration. Anti-plasma cell treatment was effective in treating skin lesions. The clinical outcome of MM-related skin changes was correlated to tumor control, whereas the prognosis of MGUS or SMM related skin lesions was favorable. Skin involvement in M-proteinemia is extremely rare and less well-known, which greatly impairs quality of life. The diagnosis and treatment of these 4 cases support the need for futher study.

Objective: To investigate the changes of the upper airway shape and respiratory function in patients with mild and moderate obstructive sleep apnea-hypopnea syndrome (OSAHS) before and after wearing mandibular advancement snore stopping devices (MASSD), providing a reference and basis for the treatment mechanisms and clinical efficacy of MASSD for patients with mild and moderate OSAHS. Methods: Sixty patients who were diagnosed with mild and moderate OSAHS by polysomnography were selected. Snoring frequency, the apnea hypopnea index and lowest oxygen saturation in 60 patients before and after treatment were compared. The patients’ upper airways were scanned by CBCT before and after wearing MASSD. In Vivo Dental software was used to reconstruct the three-dimensional shape of upper airway. The upper airway sagittal diameter, the coronal diameter, the minimum cross-sectional area and the volume of each segment were measured. The snoring frequency, the apnea hypopnea index and the lowest oxygen saturation were compared before and after treatment. Results: Before wearing MASSD, the snoring frequency, the apnea hypopnea index, and the minimum oxygen saturation of 60 patients were [946 (542,1 010)], (20.61 ± 5.19), and (78 ± 8)%, respectively. After wearing MASSD, the snore frequency [19(11,30)] and the respiratory disorder index (10.86 ± 4.31) decreased significantly and the minimum oxygen saturation increased (92 ± 3)%. Compared with before wearing MASSD, no statistically significance differences were detected (P > 0.05) except for the sagittal diameter and coronal diameter of the surface of the palatum durum. The sagittal diameter and the coronal diameter of each plane of the airway increased, and the minimum cross-sectional area of each section of the airway and the volume of each section of the airway displayed varying degrees of significant increases (P < 0.001) after wearing MASSD. Conclusion Wearing MASSD can open the airways of patients with mild and moderate OSAHS and increase the airway volume of the upper airway to improve the respiratory function.

OBJECTIVETo judge whether algesia sensitization of some acupoints is existed and whether the acupoint algesia sensitization area is expanded in the patients of intestinal cancer.

METHODSTotally, 30 patients of intestinal cancer and 30 healthy subjects were included. The electronic Von Fray was used to determine the pressure-pain thresholds at 13 acupoints relevant with gastrointestinal disorders and the reference points at the sites 1and 2lateral to those points as well as the sites at the corresponding nerve segments. Compared with the pressure-pain thresholds at the reference points of the different segments, the relative value was calculated. The changes were analyzed in the pressure-pain thresholds at the relevant acupoints on the body surface in the patients of intestinal cancer as compared with the relative pressure-pain thresholds in the healthy volunteers.

RESULTSThe pressure-pain thresholds at Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Quchi (LI 11) and Dachangshu (BL 25) in the patients of intestinal cancer were all significantly reduced as compared with those of the healthy subjects (<0.05,<0.01,<0.001). At the non-acupoint sites 1and 2lateral to those acupoints as well as at the sites of the same segments, the pressure-pain thresholds were reduced significantly as compared with the control group (<0.05,<0.01,<0.001). Particularly, the sensitization zone of Yinlingquan (SP 9) focused on the acupoint, the site 1lateral to it as well as the non-acupoint sites of the same segments (<0.01,<0.001).

CONCLUSIONThe acupoint sensitization is displayed at Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Quchi (LI 11), Dachangshu (BL 25) and Yinlingquan (SP 9) and the sensitization area is expended in the patients of intestinal cancer.
