Corneal alkali burns are a common form of corneal trauma, and their treatment has been a challenge in ophthalmology. Traditional treatments include anti-inflammatory, immunosuppressive, and corneal transplantation, with limited results. This review focuses on the research progress of mesenchymal stem cells(MSCs)and their derived extracellular vesicles(MSCs-EVs)in the treatment of corneal alkali burns. MSCs have the ability of self-renewal, multidirectional differentiation, and immunomodulation, and the MSCs-EVs inherit its function from MSCs. MSCs-EVs inherit the functions of MSCs and has lower immunogenicity and better biocompatibility, which provides a new avenue for ophthalmic treatment. In addition, bioscaffolds are used as scaffolds or drug delivery systems in tissue engineering to promote tissue regeneration due to their excellent biocompatibility and degradability. This article reviews the mechanism of action and research progress of MSCs-EVs and combined bioscaffolds in the treatment of corneal alkali burns, and explores their potential in promoting the repair of corneal alkali burns and improving vision. These findings provide new strategies for the treatment of corneal alkali burns and are expected to improve the prognosis of patients.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

Laparoscopic renal pedicle lymphatic disconnection is the most effective method for treating chyluria that has failed to respond to conservative management. Chylous hemothorax is a rare clinical occurrence resulting from the anatomic abnormality. This paper reported a case, who was admitted with painless gross hematuria for 1 month and was diagnosed with left chylous hematuria. Laparoscopic left renal pedicle lymphatic disconnection was performed, and bilateral chylous hemothorax occurred after the operation. After conservative treatment such as bilateral closed thoracic drainage and blood transfusion support, the patient recovered well. After 2 months of follow-up, there was no obvious effusion in the bilateral thoracic cavity, and the chylous test of urine fluid was negative.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been reapproved for heart failure (HF) therapy in patients with and without diabetes. However, the initial glucose-lowering indication of SGLT2i has impeded their uses in cardiovascular clinical practice. A challenge of SGLT2i then becomes how to separate their anti-HF activity from glucose-lowering side-effect. To address this issue, we conducted structural repurposing of EMPA, a representative SGLT2 inhibitor, to strengthen anti-HF activity and reduce the SGLT2-inhibitory activity according to structural basis of inhibition of SGLT2. Compared to EMPA, the optimal derivative JX01, which was produced by methylation of C2-OH of the glucose ring, exhibited weaker SGLT2-inhibitory activity (IC₅₀ > 100 nmol/L), and lower glycosuria and glucose-lowering side-effect, better NHE1-inhibitory activity and cardioprotective effect in HF mice. Furthermore, JX01 showed good safety profiles in respect of single-dose/repeat-dose toxicity and hERG activity, and good pharmacokinetic properties in both mouse and rat species. Collectively, the present study provided a paradigm of drug repurposing to discover novel anti-HF drugs, and indirectly demonstrated that SGLT2-independent molecular mechanisms play an important role in cardioprotective effects of SGLT2 inhibitors.

Obesity-related hypertension is a common hypertension as well as a common chronic disease with wide distribution and great harm to human health. In recent years, this disease has become one of the hot issues of public health due to the significant increase in prevalence. The pathogenesis and pathway of obesity-related hypertension are not yet clear, and the research on its pathogenesis has received extensive attention. Studies have shown that they are regulated in most biological processes, including differentiation, proliferation, migration, and apoptosis. The miR-200 family is a group of miRNAs, which have been suggested to play a crucial role in obesity-related hypertension and glucolipid metabolism dysfunction in recent years. This paper reviews relevant research results, suggesting that the expression level of miR-200 family in obese patients with hypertension is higher than that in healthy people, which regulates the occurrence and development of hypertension through mediating oxidative stress response and GATA expression level. This review reveals the relationship between miR-200 family and obesity-related hypertension, which offers new clues to explore potential therapeutic targets for obesity-related hypertension.

Objective:To compare the clinical outcomes of a double purse-string and bridging technique versus duct-to-mucosal pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of patients who underwent laparoscopic pancreaticoduodenectomy using the double purse-string and bridging pancreaticojejunostomy technique versus those who underwent duct-to-mucosa pancreaticojejunostomy at the Affiliated Jinhua Hospital of Zhejiang University School of Medicine from January 2016 to August 2021 were retrospectively analyzed. Of the 93 patients who underwent laparoscopic pancreaticoduodenectomy, there were 48 males and 45 females, with age of (62±10) years old. These patients were divided into two groups: patients who underwent double purse-string and bridging pancreaticojejunostomy (the double purse-string group, n=51), and patients who underwent duct-to-mucosa pancreaticojejunostomy (the duct-to-mucosa group, n=42). The clinical data of the two groups were compared. Results:All the 93 patients underwent laparoscopic pancreaticoduodenectomy successfully, and there were no deaths within 3 months of operation. Compared with the duct-to-mucosa group, the double purse-string group had significantly shorter time of pancreaticojejunal anastomosis [(32.41±8.75) vs. (47.62±8.90) min] and time of operation [(365.75±43.74) vs. (389.07±45.31) min] (all P<0.05). The postoperative pancreatic fistula rates were 9.8% (5/51) in the double purse-string group and 7.1% (3/42) in the duct-to-mucosa group. There was no significant difference between the two groups ( P>0.05). In the double purse-string group, there were 18 patients with a pancreatic duct diameter >3 mm, and 3 of these patients developed grade B pancreatic fistula, giving a grade B pancreatic fistula rate of 16.6% (3/18). In the duct-to-mucosa group, there were 11 patients with a pancreatic duct diameter >3 mm, and no patients developed grade B pancreatic fistula, giving a pancreatic fistula rate of 0(0/11). Conclusion:Compared with the duct-to-mucosa anastomosis, the double purse string and bridging pancreaticojejunostomy was technically simpler. It shortened the time of pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy, especially for patients with a non-dilated pancreatic duct.

Objective:To investiagte the ability of albumin-indocyanine green (ALICE) score, albumin-bilirubin (ALBI) score and Child-Pugh score in predicting postoperative liver failure (PHLF) in patients with hepatocellular carcinoma, and to determine the clinical value of ALICE score.Methods:The clinical data of 397 patients with hepatocellular carcinoma who underwent hepatectomy in the Department of Hepatobiliary and Pancreatic Surgery, Jinhua Hospital Affiliated to Zhejiang University from June 2015 to June 2021 were retrospectively analyzed, including 350 males and 47 females, aged (58.9±11.2) years. Univariate and multivariate logistic regression were used to analyze the risk factors of PHLF. The predictive ability of ALICE score for PHLF was evaluated by receiver operating characteristic (ROC) curve, and compared with ALBI score and Child-Pugh score.Results:There were 74 patients with PHLF and 323 patients without PHLF. Multivariate logistic regression analysis showed that Child-Pugh score ( OR=1.630, 95% CI: 1.251-2.486, P=0.034), ALBI score ( OR=1.863, 95% CI: 1.028-3.119, P=0.049) and ALICE score ( OR=1.759, 95% CI: 1.216-3.078, P=0.038) were independent risk factors for PHLF in patients with hepatocellular carcinoma, and the risk of PHLF increased with the increase of grade. The area under the ROC curve of ALICE score predicting PHLF in patients with hepatocellular carcinoma was 0.613 (95% CI: 0.564-0.662), the area under the ALBI score was 0.612 (95% CI: 0.563-0.661), and the area under the Child-Pugh score was 0.555 (95% CI: 0.505-0.605). The ALICE score was better than the Child-Pugh score, and the difference was statistically significant ( z=2.04, P=0.041). In small liver resection patients, ALICE score was better than Child-Pugh score ( z=2.61, P=0.009). There was no significant difference betwenn ALICE score and ALBI score ( z=0.06, P=0.954). Conclusion:ALICE score can predict the occurrence of PHLF in patients with hepatocellular carcinoma, especially in patients with small liver resection, its value is similar to ALBI score, but better than Child-Pugh score.

Objective:To explore the effect of systematic pain management on pain of children with traumatic limb fractures.Methods:A total of 185 children with traumatic limb fracture who were treated in Children's Hospital of Hebei Province from January 2019 to December 2020 were selected as the research objects by the convenient sampling method. According to the random number table method, they were randomly divided into the intervention group (93 cases) and the control group (92 cases) . Children in both groups were treated with fracture surgery under general anesthesia. The intervention group used systematic pain management for intervention, and the control group used conventional pain management for intervention. The operation time, wake up time, extubation time, Ramsay sedation score after wake-up and Modified Objective Pain Score (MOPS) at admission, 24, 48 h after admission, and 24, 48 h after surgery were compared between the two groups.Results:There was no statistically significant difference in operation time, wake-up time, extubation time and Ramsay sedation scores after wake-up between the two groups ( P>0.05) . On admission, there was no statistically significant difference in the MOPS scores of children between the two groups ( P>0.05) . At 24 and 48 hours after admission and 24 and 48 hours after operation, MOPS scores of the intervention group were lower than those of the control group, and the differences were statistically significant ( P<0.01) . Conclusions:Compared with conventional pain management, systemic pain management can alleviate the pain of traumatic limb fractures in children.
