Objective:To investigate the clinicopathological and genetic features of epithelioid and spindle cell rhabdomysarcoma with EWSR1-TFCP2 or FUS-TFCP2 fusion.Methods:The clinical, morphological and immunohistochemical features of 14 cases of epithelioid and spindle cell rhabdomysarcoma with EWSR1-TFCP2 or FUS-TFCP2 fusion diagnosed from January 2019 to December 2022 in the Department of Pathology, Foshan Traditional Chinese Medicine Hospital, Foshan, China were retrospectively analyzed. The cases were all subject to FISH or next generation sequencing for analysis of molecular genetic features. The literature was reviewed.Results:There were 5 males and 9 females, with the age at presentation ranging from 6 to 36 years (mean, 22 years). Tumors occurred in the head and neck (9 cases), pelvic region (2 cases), bladder (one case), right humerus (one case), and the abdominal wall, humerus and pubic at the same time (one case). Presenting symptoms varied by location but often included pain or discomfort. Most of the patients showed aggressive radiographic features with soft tissue extension. The tumors had a median size of 6.6 cm (range, 2-23 cm). The tumors were poorly defined and irregularly shaped. Microscopic examination showed diffuse proliferation of spindle or epithelioid cells. While morphologically high-grade tumors displayed obvious cytological atypia, a high mitotic count and tumor necrosis, low-grade tumors grew in sheets and fascicles composed of spindle, epithelioid cells with moderate or abundant amounts of eosinophilic cytoplasm, without pronounced cytological atypia. The tumor cells expressed Desmin, MyoD1, and Myogenin, as well as ALK, EMA, and CKpan. EWSR1/FUS-TFCP2 gene fusion was detected in 14 cases with next generation sequencing and confirmed by FISH. Six cases had EWSR1-TFCP2 fusions and 8 cases showed FUS-TFCP2 fusions. Follow-up information was available in 13 patients, ranged from 5 to 37 months. At the end of follow-up period, 7 patients died of the disease. Six patients were alive:two cases had local recurrences and metastases, two cases of recurrences, one case of metastasis and one case without recurrences and metastasis.Conclusions:Epithelioid and spindle cell rhabdomysarcomas with EWSR1-TFCP2 or FUS-TFCP2 fusion show a very aggressive clinical course, and more commonly occur in the head and neck. Their genetic hallmark is the presence of EWSR1/FUS-TFCP2 fusions. Familiarity with its clinicopathological characteristics is helpful in avoiding misdiagnoses.

African swine fever virus(ASFV)I177L gene deletion vaccine is one of the key directions of African swine fever(ASF)live attenuated vaccine research and development.In order to effec-tively distinguish between the wild-type ASFV strain and the I177L gene-deleted strain,specific primers and probes were designed based on ASFV B646L and I177L genes,respectively.After screening and optimization,a duplex real-time PCR method was developed that can simultaneously detect these two genes.The results showed that ASFV B646L and I177L genes were detected spe-cifically and simultaneously by the method developed without cross-reactions with porcine circovir-us type 2,Seneca virus A,classical swine fever virus,foot-and-mouth disease virus,porcine respira-tory and reproductive syndrome virus.The detection limits of the duplex real-time PCR for recom-binant plasmids pUC57-B646L and pUC57-I177L were 1×103 copies/mL.The intra-and inter-as-say coefficients of variation were less than 4％,respectively.Detection of 122 pork and pork prod-ucts using the duplex real-time PCR developed and the real-time PCR recommended by WOAH showed that the coincidence rates of the two methods for B646L gene detection was 100％with two amplification curves appeared in the positive results of the established methods.The method established in this study can be used for the detection of ASFV I177L gene deletion strains,which provides technical support for ASF surveillance and epidemiological investigation.

Objective To investigate the value of a nomogram model constructed from intratumoral and peritumoral magnetic resonance imaging radiomics combined with clinical characteristics in predicting the status of lymphovascular space invasion(LVSI)in cervical cancer.Methods A retrospective analysis was conducted on 178 cervical cancer patients confirmed by postoperative pathology,with 70 cases of LVSI(+)and 108 cases of LVSI(-).The patients were divided into a training set[142 cases,including 54 cases of LVSI(+)and 88 cases of LVSI(-)]and a test set[36 cases,including 16 cases of LVSI(+)and 20 cases of LVSI(-)]at a ratio of 8:2.All underwent magnetic resonance imaging before surgery,and regions of interest were manually delineated layer by layer on the T2WI sequence,with the peritumoral region being uniformly expanded outward.Univariate logistic analysis was performed on clinical factors to select independent factors for cervical cancer LVSI(+).Radiomic features were extracted separately from the intratumoral region,the peritumoral region,and the intratumoral-peritumoral region to construct radiomics models,and the differences between the peritumoral and the intratumoral-peritumoral models were compared.A combined model was established based on the radiomics scores of the optimal intratumoral-peritumoral model and clinical independent predictive factors,and a nomogram was plotted.Receiver operating characteristic curves were used to evaluate the diagnostic performance of each model,and decision curve analysis was used to assess the clinical value of the models.Results The combined model demonstrated the best performance among the various models,with AUC of 0.970 in the training set and 0.803 in the test set.Conclusion Intratumoral and peritumoral magnetic resonance imaging radiomics combined with clinical characteristics can effectively predict LVSI in cervical cancer.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

BACKGROUND/OBJECTIVES: Tibetan tea is a kind of dark tea, due to the inherent complexity of natural products, the chemical composition and beneficial effects of Tibetan tea are not fully understood. The objective of this study was to unravel the composition of Tibetan tea using knowledge-guided multilayer network (KGMN) techniques and explore its potential antioxidant and hypolipidemic mechanisms in mice.MATERIALS/METHODS: The C57BL/6J mice were continuously gavaged with Tibetan tea extract (T group), green tea extract (G group) and ddH 2 O (H group) for 15 days. The activity of total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) in mice was detected.Transcriptome sequencing technology was used to investigate the molecular mechanisms underlying the antioxidant and lipid-lowering effects of Tibetan tea in mice. Furthermore, the expression levels of liver antioxidant and lipid metabolism related genes in various groups were detected by the real-time quantitative polymerase chain reaction (qPCR) method. RESULTS: The results showed that a total of 42 flavonoids are provisionally annotated in Tibetan tea using KGMN strategies. Tibetan tea significantly reduced body weight gain and increased T-AOC and SOD activities in mice compared with the H group. Based on the results of transcriptome and qPCR, it was confirmed that Tibetan tea could play a key role in antioxidant and lipid lowering by regulating oxidative stress and lipid metabolism related pathways such as insulin resistance, P53 signaling pathway, insulin signaling pathway, fatty acid elongation and fatty acid metabolism. CONCLUSIONS This study was the first to use computational tools to deeply explore the composition of Tibetan tea and revealed its potential antioxidant and hypolipidemic mechanisms, and it provides new insights into the composition and bioactivity of Tibetan tea.

Objective:We compare the consistency, similarities and differences of operating procedures, data and conclusions of air-charged catheters(ACC) and water-filled catheters(WFC), as simultaneously using ACC and WFC in pressure-flow study(PFS).Methods:This study was a prospective, synchronously controlled study, including eligible patients who underwent PFS in the Department of Urology, Beijing Chaoyang Hospital from January 2021 to March 2021. Inclusion criteria: ① Patients need PFS for lower urinary tract symptoms like frequency of urination, urgent urination, urinary incontinence and dysuria; ② Age over 18 years old. Exclusion criteria: ① Unable to complete or cooperate during the urodynamic test; ② Patients with severe urethral stricture or acute stage urinary tract infection; ③ Pregnant women. The bladder pressure was measured continuously by using a 7FDR T-DOC ?AC three-chamber bladder pressure tube, which linked to ACC sensor and improved WFC pressure conduction module. At the same time, 7FA T-DOC ?AC single-lumen rectal pressure tube and 7F Labori-CAT411 double-lumen water sac abdominal pressure tube was used to measure the ACC and WFC rectum pressure, respectively. We recorded the Pdet, Pves and Pabd measured by ACC and WFC, at the point of initial sitting position, bladder filling at 100 ml, 150 ml, 200 ml, cough, Q max, maximum Pdet and the end of urination, and compared the mean values, differences, and consistencies of our data. Result:A total of 63 patients (26 female, 37 male) were included in this study, with an average age of 59.19 years (25-86 years old). During bladder filling phase, the mean values of Pves measured by ACC and WFC were 30.78/24.67cmH 2O (initial sitting position), 29.79/25.13cmH 2O (100 ml), 30.87/25.90cmH 2O (150 ml) and 30.95/26.17cmH 2O(200 ml), respectively, the mean value of Pabd were 30.03/24.17cmH 2O (initial sitting position), 28.81/21.78cmH 2O (100ml), 28.89/21.38cmH 2O (150ml), 28.44/21.60cmH 2O (200ml), respectively, and were significantly different at each sampling point ( P<0.01). During urination period, no significant differences were found in data( P>0.05), and the data measured with ACC and WFC system have good consistency. There were significant differences in Pves(mean 57.30/49.95 cmH 2O, respectively) and Pdet(mean 54.21/43.10 cmH 2O, respectively) between ACC and WFC in cough ( P<0.01), but there was a strong linear correlation between these data between two systems(R 2=0.792 in Pves and 0.756 in Pabd). Bland-Altman analysis showed that detrusor pressure at the maximum urine flow rate maintained good consistency between ACC and WFC, which 95% CI was -13.9 cmH 2O to 15.8 cmH 2O. Conclusions:In PFS, although the ACC measurement values (Pves and Pabd) during the filling phase are higher than those WFC readings, but the absolute measurement difference is small, so there is no practical meaning in clinical practice. There was no significant difference in detrusor pressure measured during voiding phase, which indicated that the urodynamic judgment and clinical conclusions of the two systems are highly consistent in judgment of the detrusor contractility and the bladder outlet obstruction.

Purpose: Elder self-neglect is a global public health issue and should be taken seriously at large. Nurses,usually working directly with elderly patients, have a better understanding of what factors may causeelder self-neglect. In this qualitative study, we explored the influencing factors of elder self-neglect fromthe perception of nurses in the context of Chinese culture. Methods: Face-to-face, in-depth interviews were conducted from November 2018 to December 2018.Purposive sampling was used. Twenty one participants recruited from eight geriatric wards of a generalhospital located in Wuhan were interviewed. A content analysis of qualitative nature was performed toanalyze the data. Results: Our conceptual model illustrated the findings based on the three themes of the conflict betweenpersonal recognition and social judgment, the choice between current needs and individual beliefs, aswell as the compromise between insufficient abilities and limited resources. Conclusion Nurses together with family members and social workers can help older adults improvetheir awareness of self-neglect to bridge the gap with social judgment, learn to focus on their own needs,as well as seek as much support as possible. Nurses should also respect the autonomy and selfdeterminationof elder self-neglecters because self-neglect is related to older adults' values. Furthermore,larger studies are needed to quantitatively test and refine the model.

Objective:To compare the clinical efficacy and safety of single incision mini slings (contasure needless, C-NDL) and tension-free vaginal tape obturator (TVT-O) in the treatment of pure female stress urinary incontinence(SUI).Methods:Clinical data of 107 female SUI patients who underwent C-NDL ( n=51) or TVT-O ( n=56) procedure during October 2013 and October 2017 in Department of Urology, Beijing Chaoyang Hosptial, Capital Medical University were enrolled.The age of the patients in the C-NDL and TVT-O group was (58.8±9.3) years (range: 43 to 81 years) vs.(56.9±11.4) years (range: 32 to 87 years), the cough leak point pressure was 70(20) cmH 2O ( M( Q R), 1 cmH 2O=0.098 kPa) vs. 80(25) cmH 2O. The pre- and peri-operative data, subjective cure rate, objective cure rate, quality of life, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), Incontinence Impact Questionnaire-Short Form (IIQ-7) and other complications were compared. The t test, Wilcoxon rank sum test, analysis of variance, χ 2 test andFisher exact test were applied to compare the indexes. Results:In the C-NDL and TVT-O group, the median operation time was 30(10) minutes vs. 40(30) minutes ( Z=-3.73, P<0.01). The postoperative follow-up period was 32.0(17.4) months vs.41.0(23.2)months. At the latest follow-up, the objective cure rate was 48/51 vs. 54/56 (χ 2=0.01, P=0.94), the subjective cure rate was 43/51 vs. 50/56 (χ 2=0.03, P=0.86), ICIQ-SF was 2.29±4.02 (range:0 to 13) vs. 1.71±3.67 (range:0 to 18), and IIQ-7 was 1.12±1.85 (range: 0 to 7) vs.0.70±1.70 (range: 0 to 6). The statistically significant difference in the postoperative visual pain analogue scale (VAS) were found between the two groups (0(1.5) vs.1.0(1.0), Z=3.41, P<0.01). Dysuria occurred in 2 patients in each group, vaginal pain occurred in 1 patient in the C-NDL group, groin pain occurred in 2 patients and urinary urgency occurred in 3 patients in the TVT-O group too. There were no significant difference between the complication rates of the 2 group (3/51 vs.7/51, P=0.325). Conclusion:Both C-NDL and TVT-O may be effective and reliable in the treatment of female SUI.

Objective:To develop a Self-neglect Questionnaire for the aged in China and to test its reliability and validity so as to provide an effective assessment tool for differentiating self-neglect for the aged.Methods:The initial questionnaire was developed based on former results of qualitative research, literature review and the method of Delphi expert consultation. From April to May 2018, a total of 71 elderly inpatients were selected by convenience sampling at a ClassⅢ Grade A hospital in Wuhan to investigation with item analysis. From June to October 2018, by convenience sampling a total of 314 elderly inpatients were investigated formally at a Class Ⅲ Grade A hospital in Wuhan, and the questionnaire was tested in terms of reliability and validity.Results:Finally, the Self-neglect Questionnaire induding 7 common factors and 24 items was formed. The Cronbach's α of the questionnaire was 0.875, the split-half reliability coefficient was 0.709. In content validity, the item-content validity index (I- CVI) ranged from 0.895 to 1, and the average scale-content validity index (S- CVI/Ave) was 0.987. Exploratory factor analysis extracted 7 common factors with 69.391% for the cumulative variance contribution. Conclusions:The Self-neglect Questionnaire for the aged has good reliability and validity which can be an assessment tool for self-neglect of the aged.
