Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Pancreatic β-cell failure due to a reduction in function and mass has been defined as a primary contributor to the progression of type 2 diabetes (T2D). Reserving insulin-producing β-cells and hence restoring insulin production are gaining attention in translational diabetes research, and β-cell replenishment has been the main focus for diabetes treatment. Significant findings in β-cell proliferation, transdifferentiation, pluripotent stem cell differentiation, and associated small molecules have served as promising strategies to regenerate β-cells. In this review, we summarize current knowledge on the mechanisms implicated in β-cell dynamic processes under physiological and diabetic conditions, in which genetic factors, age-related alterations, metabolic stresses, and compromised identity are critical factors contributing to β-cell failure in T2D. The article also focuses on recent advances in therapeutic strategies for diabetes treatment by promoting β-cell proliferation, inducing non-β-cell transdifferentiation, and reprograming stem cell differentiation. Although a significant challenge remains for each of these strategies, the recognition of the mechanisms responsible for β-cell development and mature endocrine cell plasticity and remarkable advances in the generation of exogenous β-cells from stem cells and single-cell studies pave the way for developing potential approaches to cure diabetes.

Transcatheter tricuspid valve intervention is the new frontier of interventional cardiology. The LuX-Valve is a radial force-independent orthotopic tricuspid valve replacement device developed in China. The LuX-Valve Plus transcatheter tricuspid valve replacement (TTVR) system is changed from the trans-atrial to the transjugular approach, which further reduces trauma and pulmonary complications compared with the first generation LuX-Valve. The first-in-human study has been completed at Zhongshan Hospital, Fudan University and an exploratory multicentre clinical study is underway. Echocardiography plays an important role in pre-TTVR screening, intraoperative guidance and postoperative evaluation and follow-up, especially two-dimensional transoesophageal echocardiography (2D-TEE) and three-dimensional transoesophageal echocardiography (3D-TEE). However, there is a lack of appropriate intraoperative guidance and assessment protocols. In this study, we briefly described the protocols and imaging considerations for intraoperative 2D-TEE and 3D-TEE to ensure the successful implantation of TTVR.

BACKGROUND: Pancreatic β-cells elevate insulin production and secretion through a compensatory mechanism to override insulin resistance under metabolic stress conditions. Deficits in β-cell compensatory capacity result in hyperglycemia and type 2 diabetes (T2D). However, the mechanism in the regulation of β-cell compensative capacity remains elusive. Nuclear factor-Y (NF-Y) is critical for pancreatic islets' homeostasis under physiological conditions, but its role in β-cell compensatory response to insulin resistance in obesity is unclear. METHODS: In this study, using obese ( ob/ob ) mice with an absence of NF-Y subunit A (NF-YA) in β-cells ( ob , Nf-ya βKO) as well as rat insulinoma cell line (INS1)-based models, we determined whether NF-Y-mediated apoptosis makes an essential contribution to β-cell compensation upon metabolic stress. RESULTS: Obese animals had markedly augmented NF-Y expression in pancreatic islets. Deletion of β-cell Nf-ya in obese mice worsened glucose intolerance and resulted in β-cell dysfunction, which was attributable to augmented β-cell apoptosis and reactive oxygen species (ROS). Furthermore, primary pancreatic islets from Nf-ya βKO mice were sensitive to palmitate-induced β-cell apoptosis due to mitochondrial impairment and the attenuated antioxidant response, which resulted in the aggravation of phosphorylated c-Jun N-terminal kinase (JNK) and cleaved caspase-3. These detrimental effects were completely relieved by ROS scavenger. Ultimately, forced overexpression of NF-Y in INS1 β-cell line could rescue palmitate-induced β-cell apoptosis, dysfunction, and mitochondrial impairment. CONCLUSION Pancreatic NF-Y might be an essential regulator of β-cell compensation under metabolic stress.

Tricuspid regurgitation (TR) interventions are under rapid development. The K-Clip? system is the first domestic transcatheter tricuspid annuloplasty system with unique clamping procedure to achieve annular reduction.Intraoperative echocardiographic monitoring procedures for transcatheter tricuspid annuloplasty have not been reported yet in China. Thus, this review aimed to propose the standard two-dimensional and three-dimensional transesophageal echocardiographic workplanes and procedures to guide and monitor the implantation of K-Clip system based on our experience in Zhongshan Hospital, Fudan University to provide a reference point for the intraoperative echocardiographic monitoring of future transcatheter tricuspid annuloplasty devices in China.

Objective:To explore multidisciplinary team (MDT) for the treatment of hip fracture in the elderly.Methods:A retrospective analysis was done of the 196 elderly patients who had been admitted to Department of Joint Surgery, Beijing Shijitan Hospital from September 2017 to December 2018 for hip fractures. They were divided into 2 groups depending on whether MDT had been applied or not. In the MDT group of 102 patients, there were 43 males and 59 females with an age of 81.9±8.4 years, and 63 femoral neck fractures and 39 intertrochanteric fractures. In the traditional treatment group of 94 patients, there were 37 males and 57 females with an age of 81.3±8.6 years, and 55 femoral neck fractures and 39 intertrochanteric fractures. The 2 groups were compared in terms of complications and mortality during hospitalization, interval from admission to surgery, total hospital stay, and Harris hip scores at 6 months after surgery.Results:There were no statistically significant differences in general data before surgery between the 2 groups, indicating comparability ( P>0.05). Eighty-four patients (89.4%) in the traditional treatment group and 98 patients (96.1%) in the MDT group underwent surgery, showing no significant difference between the groups ( χ2=3.327, P=0.068). In the patients undergoing surgery in the MDT group, the incidences of postoperative delirium [12.2% (12/98)], pulmonary infection [11.2% (11/98)], cardiogenic disease [13.3%(13/98)], electrolyte disturbance[12.2%(12/98)] and deep venous thrombosis of lower extremity [6.1% (6/98)] were significantly lower, the interval from admission to surgery (1.9 d±0.9 d) and total hospital stay (10.2 d±0.9 d) significantly shorter, and Harris hip scores (81.3±6.2) at 6 months after surgery significantly higher than those in the patients undergoing surgery in the traditional treatment group [31.0%(26/84), 22.6% (19/84), 25.0% (21/84), 28.6% (24/84), 16.7%(14/84); 3.1 d±1.6 d and 14.1 d±6.2 d; 75.4±7.8; respectively] (all P<0.05). Conclusion:In the treatment of hip fracture in the elderly, multidisciplinary team is effective in reducing complications during hospitalization, shortening the interval from admission to surgery and total hospital stay, and promoting functional recovery of the hip.

Objective To investigate the expressions of Wnt3a and Wnt5a in papillary thyroid carcinoma (PTC) and their clinical significances. Methods Immunohistochemical SABC method was used to detect the expressions of Wnt3a and Wnt5a proteins in PTC tissues and their paracancerous tissues collected from 79 patients in Dandong First Hospital from January 2014 to June 2018, and the relationships between the expressions of Wnt3a and Wnt5a proteins and clinicopathological features of PTC patients were analyzed. The expressions of Wnt3a and Wnt5a proteins in 10 pairs of fresh PTC tissues and paracancerous tissues were detected by Western blot. Results The results of immunohistochemistry showed that the positive expression rates of Wnt3a and Wnt5a proteins in PTC tissues were significantly higher than those in paracancerous tissues [69.6％ (55/79) vs. 25.3％ (20/79), 60.8％ (48/79) vs. 20.2％ (16/79)], and the differences were statistically significant (χ 2 values were 31.092 and 26.894, both P < 0.01). The results of Western blot showed that the expressions of Wnt3a and Wnt5a proteins in 10 pairs of fresh PTC tissues was significantly higher than those in paracancerous tissues(1.61±0.40 vs. 0.43±0.14, 1.38±0.291 vs. 0.36±0.13), and the differences were statistically significant (t values were 16.234 and 13.493, both P < 0.01). The expressions of Wnt3a and Wnt5a in PTC tissues were correlated with TNM stage, differentiation, extramembranous invasion and lymph node metastasis (Wnt3a: χ2 values were 6.645, 15.945, 8.783 and 11.220; Wnt5a: χ2 values were 21.525, 7.611, 17.880 and 12.581, all P < 0.05), but not with patients'age, sex and tumor diameter (all P > 0.05). There was a positive correlation between Wnt3a and Wnt5a proteins expressions in PTC (r = 0.597, P < 0.01).Conclusion The abnormal expressions of Wnt3a and Wnt5a proteins in PTC may be related to the development of PTC.

Objective To investigate the regulation of T cells in the process of liver regeneration using a model of mice after 70% liver resection.Methods We performed 70% hepatectomy in T-cell-deficient mice and control mice.The liver mass and body mass ratio, BrdU infiltration level, proliferating cell nuclear antigen (PCNA),expression of M phase marker protein p-HDAC3, and serum transaminase levels were measured.Results The recovery of liver mass and body mass ratio of thymus-deficient mice occurred significantly later than that of control mice.The peak time of BrdU infiltration levels and the expression of PCNA and p-HDAC3 in T-cell-deficient mice were later than in control mice, but the degree of liver injury was lower.Conclusion T cells are involved in the regulation of liver regeneration, and the absence of T cells delays the process of liver regeneration.

Objective: To investigate the effects of apolipoprotein E deficiency (Apo E^-/-) on plasma and lipoprotein distribution of sphingosine-1-phosphate (S1P) in mice. Methods: Five male or female Apo E^-/- or wild type (WT) mice were fed with chow diet and sacrificed at 32-week-age and plasma was collected. The constituents of lipoprotein(very low density lipoprotein (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL)) were separated by ultracentrifuge. The protein concentration of constituents was detected by BCA protein quantitative kit, and the S1P concentration in plasma and various lipoprotein constituents was detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Western blot was used to determine the plasma, liver, and kidney protein expression of apolipoprotein M(Apo M), which is considered as specific ligand of S1P.The S1P concentration in plasma and various constituents of lipoprotein in the Apo E^-/- mice was compared to respective WT mice. Results: (1)Plasma S1P content was significantly higher in the Apo E^-/- groups than that of WT groups (male: (535.7±78.5)nmol/L vs. (263.3±22.0)nmol/L; female: (601.1±64.0)nmol/L vs. (279.0±33.9)nmol/L; all P<0.01). (2) Compared with WT mice, S1P content in non-HDL(LDL+ VLDL) was significantly higher in Apo E^-/- mice (male: (504.9±52.8)nmol/L vs. (28.7±9.0)nmol/L; female: (427.7±27.4) vs. (27.8±4.7)nmol/L; after standardization of protein concentration, male: (385.0±41.2)pmol/mg protein vs. (71.4±6.6)pmol/mg protein; female: (330.2±22.0)pmol/mg protein vs. (67.2±12.1)pmol/mg protein; all P<0.01). (3) The expression of Apo M in plasma, liver and kidney was significantly higher in Apo E^-/- groups than that of WT groups(all P<0.05). Conclusion The deficiency of Apo E could lead to upregulated S1P expression in the non-HDL, the underlying mechanism might be the increased transfer of HDL into the non-HDL by Apo M-S1P.
