Objective:To understand the predictive effect of orthostatic hypotension on frailty in nursing homes, and the effect of frailty on heart rate and blood pressure in supine positionand orthostatic position.Methods:A total of 214 elderly cases in three nursing homes (the Golden Years of Jinjialing Retirement Life Center, Hangzhou Boyang Pension Service Co., Ltd, Hangzhou Langhe International Medical Care Center) were interviewed by the general information questionnaire, the Frail Scale and Barthel Index. Systolic blood pressure, diastolic blood pressure, and heart rate were measured by electronic sphygmomanometer in supine position and orthostatic position of 1 and 3 minutes.Results:The incidence of frailty combined with orthostatic hypotension was 26.64%(57/214) in the elderly in nursing homes. The incidence of orthostatic hypotension in the robust elderly, pre-frailty and frailty gradually increased, 14.29%(5/35), 20.00%(12/60), 47.90%(57/119). The differences of heart rate and systolic blood pressure in supine position between the elderly with and without frailty were significant ( t=2.16, 3.25, P<0.05), the differences of systolic pressure difference in orthostatic position of 1 and 3 minutes between the elderly with and without frailty were significant ( H=3.16, 4.08, P<0.01). There was significant difference in systolic pressure between the prefrail elderly and the elderly without frailty in lying position ( t=2.02, P<0.05). The differences of systolic and diastolic pressure differences in orthostatic position of 3 minutes between the frail elderly and pre-frail elderly were significant ( H=3.13,2.44, P<0.05). Ordered Logistic regression analysis showed that orthostatic hypotension was a risk factor for frailty ( OR=2.425, 95% CI were 1.133-4.988, P<0.05). Conclusions:Elderly adults with orthostatic hypotension in nursing homes have a higher prevalence of frailty. Frailty also impairs blood pressure regulation during postural changes. Nurses should attach importance to the assessment, education and intervention of frailty and orthostatic hypotension.

Gingival recession could result in root exposure, dental hypersensitivity and poor aesthetics. It has been demonstrated that varieties of root coverage procedures can significantly improve gingival recession in short-term (≤6 months), of which coronally advanced flap combined with connective tissue graft is the gold standard technique for treatment of gingival recession. It could obtain the optimally complete root coverage and maintain long-term stability (≥2 years). However, clinical knowledge about the long-term effectiveness of the other alternative graft materials remain very limited. Based on the existing clinical evidence, this article reviews coronally advanced flap, coronally advanced flap combined with connective tissue graft or alternative graft materials, with particular attention to the long-term stability of them, in order to provide reference for the design of further clinical trials and the plan of clinical treatments.

Objective To investigate the effect of resveratrol (RSV) on epithelial-mesenchymal transition of MDA-MB-231 cells by down-regulating POLD1 expression. Methods CCK-8 was used to detect the effect of RSV on the activity of MDA-MB-231 cells. POLD1-OE and POLD1-NC cell lines were constructed by transfecting MDA-MB-231 cells with recombinant lentivirus. Western blot was used to detect the expression of POLD1, E-cadherin, N-cadherin and Vimentin after RSV treatment. Transwell invasion experiment and the scratch test were used to detect the cells invasion and migration abilities of each experimental group. Results RSV could significantly inhibit the survival of MDA-MB-231 cells, reduce the expression of POLD1, N-cadherin and Vimentin, increase the expression of E-cadherin, and inhibit the abilities of cell invasion and migration. Increasing the POLD1 expression could reduce the above-mentioned biological effects of RSV on MDA-MB-231 cells. Conclusion RSV could significantly inhibit the viability and EMT of MDA-MB-231 cells by down-regulating the expression of POLD1.

The geriatrics department of Zhongnan Hospital covers all subspecialties of internal medicine with six separated wards, so it is difficult to manage and teach the students who participate in standardized training for resident physicians. In the residents' standardized training of geriatrics department, the interactive support platform named micro-teaching assistant was applied to carry out teaching activities such as classroom check-in, classroom testing and classroom discussion of teaching rounds and small lectures. It not only effectively manages the teaching order, but also improves students' enthusiasm and autonomy by encouraging them to participate in classroom interaction actively. The case analysis quiz and interactive discussion have a good effect on consolidating and deepening the students' professional knowledge, and improving the ability of clinical analysis and problem solving. The attendance rates, class discussion and test scores were recorded in a real and objective way, so that teachers can observe the whole process of students' learning and then make a formative assessment. At the same time, teachers are urged to adjust the teaching contents and progress in time, so as to achieve the goal of promoting "teaching" and "learning" mutually.

Objective:To study the clinicopathological features, immunophenotype, molecular genetic characteristics and prognosis of renal cell carcinoma associated with TFEB gene rearrangement (TFEBr-RCC).Methods:Eight cases of TFEBr-RCC diagnosed at the West China Hospital of Sichuan University from 2014 to 2022 were collected for clinicopathological, immunohistochemical, fluorescence in situ hybridization and RNA sequencing analyses, with review of literature.Results:Six patients were male and two were female. The patient ages ranged from 25 to 50 years (mean: 34 years, median: 32 years). The tumors were present in the right kidney (3 cases) or the left kidney (5 cases). The maximum diameters of the tumors ranged from 4.0 cm to 18.5 cm, with an average of 8.5 cm. Histologically, majority of the cases (5/8) showed typical biphasic "pseudorosette" structure, while the remaining three cases demonstrated atypical morphology that was similar to epithelioid angiomyolipoma or clear cell renal cell carcinoma. Immunohistochemical study showed positivity of TFEB (8/8), PAX8 (8/8), MART-1 (7/7), and HMB45 (5/6). Interestingly, PD-L1 was variably expressed in all five tested cases. Staining for TFE3 in all cases was negative. TFEB translocation was verified in all 8 cases using TFEB fluorescence in situ hybridization. RNA sequencing showed MALAT1-TFEB gene fusion in 4 of the 5 tested cases (two of which showing novel MALAT1-TFEB fusion sites), and one case with a novel ACTB-TFEB gene fusion. Patient follow-ups ranged from 5 to 96 months (average 47 months). All patients were alive without recurrence or metastasis.Conclusions:TFEBr-RCC tends to occur in young adults and has a good prognosis. Histologically, most of the cases show characteristic biphasic structure, and some cases show epithelioid angiomyolipoma-like or clear cell RCC-like morphology. Immunohistochemical reactivity to TFEB, melanocytic markers and PD-L1 is characteristic. MALAT1-TFEB gene fusion is the most common molecular change, with variable fusion sites.

Objective:To construct the pregnancy risk prediction model of chronic kidney disease (CKD) pregnant women by analyzing their renal function and pregnancy outcome in the first trimester.Method:Totally 313 CKD women with 322 pregnancies who had deliveries in Peking University First Hospital from March 2009 to December 2018 were retrospectively analyzed. The history of kidney disease and renal function in the first trimester were collected, and the relationship between CKD and premature delivery, low birth weight infants, severe preeclampsia and fetal loss were analyzed.Result:Among 322 pregnancies with CKD, 120 (37.3%, 120/322) had adverse pregnancy outcomes. CKD stage, serum creatinine, urea, albumin, hemoglobin, 24-hour urine protein quantity and whether complicated with hypertension were independent predictors of adverse pregnancy outcome. A prediction model logit (P)=2.107+0.255×24-hour urine protein quantitative (g/24-hour)-0.107×albumin (g/L)+1.677×whether complicated with hypertension (1 or 0)+ 0.639×CKD stage was established. The area under curve value of the model was 0.812, the best threshold, sensitivity, specificity and Yoden index were 0.436, 0.658, 0.856 and 0.802, respectively.Conclusion:CKD stage, serum albumin, 24-hour urine protein quantity in the first trimester and hypertension are the main risk factors of adverse pregnancy outcome, which could predict the occurrence of adverse pregnancy outcome of CKD pregnant women and deserve further study.
