1. Advance in Regulation of Expression of Brain Aquaporin 4 (review)
Chinese Journal of Rehabilitation Theory and Practice 2007;13(8):724-726
The expression of brain aquaporin 4 (AQP4) is different at the different stages of cellular differentiation, and distribution of brain AQP4 is affected by the existence of endothelial cells. Other factors including osmolality, ammonia, hypoxia, temperature, hormone, C-type natriuretic peptide, lead, complement inhibitor, lipopolysaccharide can also influence AQP4 expression in astrocytes. However, the regulating mechanisms for brain AQP4 expression are not clear. Protein interaction, protein kinase C (PKC) through protein phosphorylation, mitogen-activated protein kinase signal pathway, Ca2+ signaling cascade signal pathway and transcription factor pathway have been proposed, among which phosphorylation of PKC for the inhibition of AQP4 is frequently studied.
2.Aquaporin-1 and Aquaporin-9 Expressed by Reactive Astrocytes after Traumatic Brain Injury in Rat
Chinese Journal of Rehabilitation Theory and Practice 2009;15(2):129-131
Objective To investigate the expression changes of aquaporin-1 (AQP1) and aquaporin-9 (AQP9) in rats after traumatic brain injury, and explore the roles of AQP1 and AQP9 in the development of brain edema.Methods In an impact-acceleration head injury model of rat, brain water content was measured by wet-dry weight method at 1 h, 6 h, 24 h, 48 h and 168 h after brain trauma. The expressions of AQP1 and AQP9 in brains were investigated by immunohistochemistry and Western blot.Results Brain water content increased in the injuried brain tissues after 1 h post-injury, reached peak at 24 h and returned at 168 h. Both expressions of AQP1 and AQP9 were induced in reactive astrocytes adjacent to injury sit at 6 h and 24 h after brain trauma. Staining of AQP1 in the endothelial cells was not present in normal rat brains but appeared strong after brain trauma.Conclusion A remarkable induction expression of AQP1 or AQP9 after brain trauma may participate in the development of brain edema.
3.Research progress of intestinal microorganisms and pathogenesis of diabetes mellitus
Journal of Preventive Medicine 2022;34(3):253-257
Abstract
As the largest human microecosystem, intestinal microorganisms participate in human material and energy metabolisms and pose a significant impact on human health. Diabetes mellitus is likely to cause imbalance of abundance and component alterations in intestinal microorganisms, and reduce the diversity and balance, leading to intestinal microflora dysregulation. It has been shown that intestinal microflora dysregulation may promote diabetes development and progression through the reduction of intestinal microbial metabolites, inflammatory reaction and insulin resistance. This review summarizes the involvement of intestinal microorganisms in the pathogenesis of diabetes through metabolites including short-chain fatty acid, bile acid and lipopolysaccharide, and describes the current status of intestinal microorganisms-mediated treatments for diabetes, so as to provide the theoretical basis for the researches on diabetes and intestinal microorganisms.
4.Effects of aerobic exercises therapy on platelet function in phase Ⅰ essential hypertension
Chinese Journal of General Practitioners 2008;7(10):671-673
Objective To study the effects of aerobic exercises on platelet function in patients with phase Ⅰ essential hypertension (EH). Methods Low-intensity aerobic exercises therapy was given to 36 patients with phase Ⅰ EH for three months. Changes of their blood pressure, heart rate, platelet aggregation rate (PAGTmax), alpha-granule membrane protein (GMP-140) and mean platelet volume (MPV) werer ecorded and compared to those in 36 normal healthy controls. Results As compared to those in controls,PAGTmax, level of GMP-140 and MPV were all increased in patients with phase Ⅰ EH before exercises therapy(t=15.221, 10. 916 and 16. 401, respectively, all P < 0. 01 ). After exercises therapy, 24-hour mean blood pressure decreased in association with reduction in PAGTmax to (0. 80±0. 05)% from (0. 88±0. 08) % (t=4. 323, P < 0. 05), level of GMP-140 decreased to ( 28±20) μg/L from (57±23 ) μg/L ( t=15.049, P<0.01) and MPV decreased to (9.0±0.9)fl from (9.1±0.9)fl (t=5.518, P <0.05) before it. But, there was no significant difference in these in dicators of platelet function in controls before and after exercise therapy (P>0.05). Conclusions Aerobic exercises therapy could be effective in lowering blood pressure in patients of mild EH with increased platelet activation, as well as inhibition ontheir platelet activation.
5.Application of enhanced recovery after surgery in pancreatic surgery
Chinese Journal of Digestive Surgery 2015;14(1):29-32
Enhanced recovery after surgery (ERAS) includes preoperative education,intraoperative effective anaesthetization,analgesia,precision surgical techniques and postoperative early rehabilitation.Because of special location of the pancreas,difficulty of surgical techniques,longtime of learning and high incidence of postoperative complications,the application of ERAS in pancreatic surgery is restricted.While ERAS could reduce the stress after surgery and the incidence of complications,promote the recovery of patients,shorten the duration of hospital stay and reduce the expenses,which are confirmed by clinical practice.ERAS is the trend of the development of pancreatic surgery.How to balance the optimal prognosis and speed recovery is need to be resolved by pancreatic surgeons.

9. Relationship between acute hyperglycemia and prognosis in patients following spontaneous intracerebral hemorrhage
Chinese Journal of Cerebrovascular Diseases 2011;8(4):172-176
Objectives: To investigate the relationship between acute hyperglycemia level and prognosis in patients following spontaneous intracerebral hemorrhage. Methods: A total 661 consecutive patients with acute intracerebral hemorrhage (from symptom onset to hospital and evaluated ≤24 hours) were admitted to West China Hospital, Sichuan University from March 1, 2002 to March 1, 2009 were recruited prospectively. The blood glucose levels of the patients and other clinical materials related to the prognosis were collected comprehensively. Hyperglycemia was defined as the blood glucose level ≥8 mmol/L at admission. The mortality and disability (as modified Rankin scale ≥3) of the patients 1 year after intracerebral hemorrhage were followed up. Multivariate logistic regression was used to analyze the relationship between hyperglycemia and prognosis. Results: A total of 661 patients with intracerebral hemorrhage were recruited. Circled digit oneOf the patients, 194 (29.3%) had hyperglycemia and 65 (9.8%) had diabetes mellitus. Circled digit twoThe National Institutes of Health Stroke Scale (NIHSS) score were positively correlated with the admission random blood glucose levels significantly (r = 0.392, P = 0.000). Circled digit threeCompared to the patients with normal blood glucose, the risk of death in patients with hyperglycemia was 4.357 times of those with normal blood glucose at 1 year (OR = 4.357; 95 % CI: 2.586-7.340), and the risks of mortality/disability was 3.117 times of those with normal blood glucose at 1 year (OR = 3.117; 95% CI: 1.888-5.144). Conclusion: The blood glucose levels on admission showed significant positive correlation with the severity of the disease. The random glucose level ≥8 mmol/L on admission might be an independent risk factor influencing the prognosis of patients 1 year after spontaneous intracerebral hemorrhage.
