Improvement of cognitive function by escitalopram and paroxetine in patients with first-episode depressive disorder and its relationship with thyroid hormone levels / 四川精神卫生

BackgroundThe incidence of cognitive impairment in patients with depressive disorder is high， and the causes and mechanisms of which deserve more attention. It is usual that the thyroid hormone levels in patients with depressive disorder alter. Further research is needed to explore whether the cognitive function changes in patients with depressive disorder are related to thyroid hormone levels. ObjectiveTo explore the improvement of cognitive function in patients with first-episode depressive disorder after escitalopram and paroxetine treatment， and to analyse its correlation with thyroid hormone levels， so as to look for potential biomarkers of cognitive function change in patients with depressive disorder. MethodsFrom March 2021 to March 2022， 120 patients who met the diagnostic criteria of the International Classification of Diseases， tenth edition （ICD-10） for depression and were hospitalized at Shandong Mental Health Center were selected as the research objects. They were randomly divided into two groups by random number table method with 60 patients in each group. The two groups were treated with escitalopram （starting dose 5 mg/d） and paroxetine （starting dose 20 mg/d） for 6 weeks. Before and 6 weeks after the treatment， levels of thyroid stimulating hormone （TSH）， free thyroxine （FT4） and free triiodothyronine （FT3） were tested respectively. Depression degree and cognitive function level were assessed using the Hamilton Depression Scale-17 item （HAMD-17） and Montreal Cognitive Assessment （MoCA）， respectively. Pearson or Spearman correlation analysis was used to examine the correlation between the MoCA score difference before and after the treatment and the post-treatment level of thyroid hormone. ResultsBefore and 6 weeks after the treatment， the time effect of HAMD-17 total score in both groups was statistically significant （F=1 236.568， P<0.01）. Also， the time effect， group effect as well as interaction effect of time and group of MoCA total score in both groups were statistically significant （F=79.186， 6.026， 20.417， P<0.05 or 0.01）. The time effect， group effect as well as the interaction effect of time and group for FT3 level and FT4 level were statistically significant in both groups （F=75.973， 20.287， 0.961， 84.194， 0.142， 8.299， P<0.05 or 0.01）. According to the simple effect analysis. After the treatment， the MoCA total score in both groups was higher than that before treatment， while FT3 and FT4 levels were lower than those before treatment （F=15.864， 5.421， 8.524， 6.443， 7.628， 3.639， P<0.01）. After the 6-week treatment， the MoCA total score as well as FT3 and FT4 level differences in escitalopram and paroxetine groups were of statistical significance （t=5.841， -0.705， -2.349， P<0.05 or 0.01）. The MoCA score difference before and after treatment in paroxetine group was positively correlated with FT3 and FT4 levels after treatment （r=0.276， 0.382， P<0.05 or 0.01）. ConclusionBoth escitalopram and paroxetine can improve cognitive function in patients with first-episode depressive disorder. The improvement may be related to the changes in serum FT3 and FT4 levels.

Application value of 3D printed model in hemostasis training for laparoscopic sleeve gastrectomy / 中华消化外科杂志

Objective:To investigate the application value of 3D printed model in hemostasis training for laparoscopic sleeve gastrectomy.Methods:The retrospective and descriptive study was conducted. Data were collected from six surgeons who participated in hemostasis training for laparoscopic sleeve gastrectomy using 3D printed model at Zhejiang Provincial People′s Hospital in July 2023. All participants were male, aged (33.5±9.9)years. A 3D printed model simulating bleeding during laparoscopic sleeve gastrectomy was created using hydrogel. Videos were recorded to document the surgeons′ hemostasis techniques and outcomes during laparoscopic sleeve gastrectomy. Two external expert reviewers blindly assessed the training videos using the objective structured assess-ment of technical skills (OSATS) scoring system to evaluate mesentery mobilization, vessel exposure, vessel clipping and bleeding after vessel clipping. Observation indicators: (1) face validity and content validity of the 3D printed model; (2) validity verification of the 3D printed model. Measurement data with normal distribution were represented as Mean± SD. Comparison between groups was conducted using the t test. Results:(1) Face validity and content validity of the 3D printed model. The surgeons′ scores for overall impression, fidelity, texture, appearance, workspace and tactile similarity of the 3D printed model were 4.5±0.6, 4.0±0.6, 3.7±0.5, 4.2±0.8, 3.8±0.8 and 4.2±0.4, respectively. The surgeons′ scores for similarity to real scenarios, operation convenience, learning curve shortening and operation skills improving, patient risk reduction, trainee′s interest enhancing, confidence increasing and recommendation for promotion were 4.0±0.6, 4.2±0.8, 4.3±0.8, 4.3±0.5, 4.3±0.5, 4.0±0.6 and 4.8±0.4, respectively. (2) Validity verification of the 3D printed model. The OSATS scores and operation time to treat bleeding during laparoscopic sleeve gastrectomy for expert surgeons were 18.7±0.6 and (125±12)seconds, respectively, versus 13.7±1.5 and (212±51)seconds for junior doctors, showing significant differences between the two groups ( t=5.30, -2.89, P<0.05). Conclusion:The 3D printed model effectively simulates bleeding scenarios during laparoscopic sleeve gastrectomy and distinguishes between different technical levels of expertise.

Polygalacin D inhibits the growth of hepatocellular carcinoma cells through BNIP3L-mediated mitophagy and endogenous apoptosis pathways / 中国天然药物

Platycodon grandiflorum (Jacq.) A. DC. is a famous medicinal plant commonly used in East Asia. Triterpene saponins isolated from P. grandiflorum are the main biologically active compounds, among which polygalacin D (PGD) has been reported to be an anti-tumor agent. However, its anti-tumor mechanism against hepatocellular carcinoma is unknown. This study aimed to explore the inhibitory effect of PGD in hepatocellular carcinoma cells and related mechanisms of action. We found that PGD exerted significant inhibitory effect on hepatocellular carcinoma cells through apoptosis and autophagy. Analysis of the expression of apoptosis-related proteins and autophagy-related proteins revealed that this phenomenon was attributed to the mitochondrial apoptosis and mitophagy pathways. Subsequently, using specific inhibitors, we found that apoptosis and autophagy had mutually reinforcing effects. In addition, further analysis of autophagy showed that PGD induced mitophagy by increasing BCL2 interacting protein 3 like (BNIP3L) levels.In vivo experiments demonstrated that PGD significantly inhibited tumor growth and increased the levels of apoptosis and autophagy in tumors. Overall, our findings showed that PGD induced cell death of hepatocellular carcinoma cells primarily through mitochondrial apoptosis and mitophagy pathways. Therefore, PGD can be used as an apoptosis and autophagy agonist in the research and development of antitumor agents.

Objective:To evaluate the laparoscopic sleeve gastrectomy combined with hiatal hernia repair surgery for weight loss and antireflux.Methods:This study included 21 obese patients with gastroesophageal reflux who underwent laparoscopic sleeve gastrectomy at the Weight Loss Metabolism Center of the Department of Hepatobiliary and Pancreatic Surgery of Zhejiang Provincial People's Hospital from Dec 2019 to Dec 2020. Patients were divided into simple bariatric surgery group (9 cases) and simultaneous combined surgery group (12 cases).Results:In the combined surgery group, 1 case had postoperative gastric leakage. The postoperative body weight, waist circumference, and BMI indexes of the two groups showed a downward trend ( F=5.154, P=0.013; F=14.319, P<0.001; F=6.725, P=0.004). There was a statistically significant difference in the excess weight loss in both the two groups at 6 months after the operation compared to 1 month after the operation ( t=8.927, P<0.001; t=8.926, P<0.001). There was no statistically significant difference in postoperative lower esophageal sphincter resting pressure and Gerd symptom score in the bariatric surgery group compared with preoperative ( t=-0.891, P=0.507; t=0.629, P=0.298). The postoperative Gerd symptom score of the patients in the combined surgery group was significantly lower than that before the operation, and the resting pressure of the lower esophageal sphincter was significantly higher than that before the operation, ( t=-10.539, P<0.001; t=5.066, P=0.038). Conclusion:Combined surgery have the same weight loss effect as in simple bariatric surgery in obese patients with gastroesophageal reflux, in addition to stronger anti-reflux effect.

The hemoglobin level in the observation group was significantly higher than that in the control group ( P<0.05). Conclusions:Laparoscopic splenectomy and pericardial devascularization with trans-artery pressure perfusion autologous transfusion can increase post-operative hemoglobin value effectively.

Astragaloside IV suppresses post-ischemic natural killer cell infiltration and activation in the brain: involvement of histone deacetylase inhibition / 医学前沿

Natural killer (NK) cells, a type of cytotoxic lymphocytes, can infiltrate into ischemic brain and exacerbate neuronal cell death. Astragaloside IV (ASIV) is the major bioactive ingredient of Astragalus membranaceus, a Chinese herbal medicine, and possesses potent immunomodulatory and neuroprotective properties. This study investigated the effects of ASIV on post-ischemic brain infiltration and activation of NK cells. ASIV reduced brain infarction and alleviated functional deficits in MCAO rats, and these beneficial effects persisted for at least 7 days. Abundant NK cells infiltrated into the ischemic hemisphere on day 1 after brain ischemia, and this infiltration was suppressed by ASIV. Strikingly, ASIV reversed NK cell deficiency in the spleen and blood after brain ischemia. ASIV inhibited astrocyte-derived CCL2 upregulation and reduced CCR2

Formation of gap junctions between adipose stem cells-derived Schwann cells in a rat model of dyskinesia induced by brain injury / 南方医科大学学报

OBJECTIVE@#To investigate the formation of gap junctions between Schwann cells derived from differentiated adipose stem cells implanted in a rat model of dyskinesia induced by brain injury and its positive effect in promoting functional recovery of the rats.@*METHODS@#In a rat model of hemiplegia induced by motor cortex injury, adipose stem cells or Schwann cells differentiated from adipose stem cells, either with or without RNAi-mediated silencing of Cx43, were transplanted orthotopically in the lesion. The recovery of the motor function of the rats was observed and scored after the transplantation. Rat brain tissues were sampled to detect the expressions of nerve growth factor (NGF) using Western blotting and RT-PCR.@*RESULTS@#All the 3 cell transplantation therapies obviously improved the motor function scores of the rats as compared with the control rats. The expression of NGF in the brain tissue was significantly lower in the control group than in the cell transplantation groups. NGF expression in the brain tissues of rats receiving transplantation of Schwann cells with Cx43 gene silencing was lower than that in rats receiving Schwann cells without Cx43 silencing, and was similar with that in rats transplanted with adipose stem cells. The results of RT-PCR showed that NGF mRNA level in the control group was significantly lower than that in the other 3 groups. NGF mRNA expression was the highest in Schwann cell group without Cx43 silencing, followed by adipose stem cell group, and then by Schwann cell group with Cx43 silencing.@*CONCLUSIONS@#In the rat model of dyskinesia induced by brain injury, transplantations of adipose stem cells and adipose stem cells-derived Schwann cells both promote the functional recovery of brain damage, in which gap junction protein Cx43 plays an important role to promote functional gap junction formation possibly by enhancing NGF expression.

Objective To evaluate the concept of artery first and total mesopancreatic excision in radical resection of pancreatic head carcinoma through both anterior and posterior approaches.Method The anterior approach was to identify the superior mesenteric artery (SMA) and the posterior approach to confirm the possibility of negative margin at the origin of SMA,on the posterio-lateral vascular wall of superior mesenteric vein (SMV) and the supposed posterior of the mesopancreas.The resection scope were with the celiac trunk and common hepatic artery as the upper boarder,the SMA as the left boarder,the inferior mesenteric vein (IMA) level as the lower boarder,to achieve a complete mesopancreatic excision,namely the en bloc resection of all the involved nerve,the lymph tissue and vascular tissue along the right side of the axial composed by SMA and celiac trunk.Results Of the 15 patients,11 had radical Whipple procedure,among which 2 had a combining SMV resection and reconstruction.1 case suffered from delayed gastric emptying and 2 cases from bile leakage.There was no mortality.The postoperative pathology reported carcinoma in all 11 cases,with duodenum and low bile duct involved in 4 cases,with the duodenum involved in 6 cases,no surrounding tissue involvement was identified in 1 case.Nerve involvement was found in 7 (7/11),vascular involvement in 10 (10/11),and lymphnode metastasis was (2.5 ± 3.8/12.9 ± 4.9).Conclusions The radical resection of pancreatic head carcinoma using the concept of artery first and the total mesopancreatic excision is helpful for an early evaluation of the possibility of radical resection and guarantees negative margins.

Association of chronic hydrocephalus after aneurysmal subarachnoid hemorrhage with transforming growth factor-β1 levels and other risk factors / 南方医科大学学报

<p><b>OBJECTIVE</b>To study the role of transforming growth factor-β1 (TGF-β1) levels and other risk factors in the occurrence of chronic hydrocephalus after aneurysmal subarachnoid hemorrhage (aSAH).</p><p><b>METHODS</b>Patients treated for aSAH in our hospital between January, 2007 and June, 2012 were divided into non-hydrocephalus group and hydrocephalus group. TGF-β1 levels in the cerebrospinal fluid (CSF) were compared between the two groups at different time points. A retrospective analysis was conducted to identify the potential risk factors for chronic hydrocephalus, which were subsequently confirmed by Logistic regression analysis.</p><p><b>RESULTS</b>Of the 129 patients enrolled, 16 (12.4%) developed chronic hydrocephalic with an average diagnosis time of 31.6∓17.0 days. In patients with chronic hydrocephalus, TGF-β1 level in the CSF increased significantly on the 13th day following aSAH (P<0.05). Retrospective analysis showed that the patients with hydrocephalus and those without had significant differences in history of hypertension, times of SAH, Hunt-Hess classification, ventricular expansion, aneurysm position, Fisher classification, ventricular hemorrhage score and intracranial infections (P<0.05). Logistic regression analysis identified ventricular expansion, aneurysm position, Fisher classification, ventricular hemorrhage score and postoperative intracranial infections as significant risk factors for the occurrence of chronic hydrocephalus (P<0.05).</p><p><b>CONCLUSIONS</b>In adult patients with aSAH, the risk factors for chronic hydrocephalus include ventricular expansion, aneurysm position, Fisher classification, ventricular hemorrhage score and postoperative intracranial infections. These risk factors can have greater clinical value than TGF-β1 levels in the CSF in predicting the occurrence of chronic hydrocephalus following aSAH.</p>
