RESUMO
@#AIM: To investigate the early changes of corneal higher-order aberrations(HOAs)of the anterior surface, posterior surface, and total cornea after femtosecond laser-assisted <i>in situ</i> keratomileusis(FS-LASIK)in mild to moderate myopic and high myopic patients. <p>METHODS: This retrospective study included 129 patients(129 eyes)underwent FS-LASIK surgery from December 2018 to December 2019. Treated eyes were divided into two groups, according to the preoperative spherical equivalent(SE): mild to moderate myopic group(<-6.0D, 76 eyes)and high myopic group(≥-6.0D, 53 eyes). Corneal HOAs of the anterior surface, posterior surface, and total cornea were measured by Pentacam anterior segment analysis system preoperatively and 6mo postoperatively. <p>RESULTS: The tHOAs, spherical aberrations and horizontal coma of the anterior surface and total cornea, significantly increased in both groups 6mo postoperatively(all <i>P</i><0.01). And more tHOAs, spherical aberrations and horizontal coma of the anterior surface and total cornea were induced in high myopic group than mild to moderate myopic group postoperatively(all <i>P</i><0.01). The horizontal coma of the posterior surface, significantly increased in both groups 6mo after operation(all <i>P</i><0.01). And more horizontal coma of the posterior surface were induced in high myopic group than mild to moderate myopic group postoperatively(<i>P</i><0.01). Changes in anterior surface and total corneal tHOAs, spherical aberrations and horizontal coma were related to the SE(all <i>P</i><0.01).<p>CONCLUSION:Anterior and total corneal tHOAs, spherical aberrations and horizontal coma, significantly increased after FS-LASIK, and aberration changes were related to SE. Whereas posterior corneal HOAs remained stable except horizontal coma. The long-term effect should be investigated in the future.
RESUMO
This study aims to explore the effect and mechanism of Jiao-tai-wan (JTW) on systemic and tissue-specific inflammation and insulin resistance in obesity-resistant (OR)rats with chronic partial sleep deprivation (PSD).OR rats with PSD were orally given JTW and Estazolam for 4 weeks.The amount of food intake and metabolic parameters such as body weight increase rate,fasting plasma glucose (FPG),fasting insulin (FINS),homeostasis model assessment-insulin resistance (HOMA-IR) and plasma inflammatory markers were measured.The expression levels of circadian proteins cryptochrome 1 (Cry1)and cryptochrome 2 (Cry2) in hypothalamus,adipose and liver tissues were also determined.Meanwhile,the mRNA expression of inflammatory markers,activity of nuclear factor kappa B (NF-κB) p65 protein,as well as the expression levels of insulin signaling pathway proteins in hypothalamus,adipose and liver tissues were measured.Additionally,cyclic adenosine 3',5'-monophosphate (cAMP) and activity of vasodilator-stimulated phosphoprotein (VASP)in hypothalamus tissue were measured.JTW significantly decreased the body weight increase rate and food intake,ameliorated systemic inflammation and insulin resistance.JTW effectively ameliorated inflammation and increased PI3K/AKT signaling activation in hypothalamus,adipose and liver.Interestingly,all these changes were associated with the up-regulation of circadian gene Cryl and Cry2 protein expression.We also found that in hypothalamus tissue of P SD rats,down-regulation of Cry 1 and Cry2 activated cAMP/PKA signaling and then led to inflammation,while JTW inhibited this signaling.These results suggested that JTW has the beneficial effect on ameliorating inflammation and insulin resistance in partially sleep-deprived rats by up-regulating Cry expression.

RESUMO
<p><b>OBJECTIVE</b>To explore the effect and mechanism of Jiaotai Pill (, JTW) on intestinal mucosal damage in rats with chronic partial sleep deprivation (PSD).</p><p><b>METHODS</b>Obesity resistant (OR) rats were selected, and underwent 4 h PSD by being exposed to environmental noise for 4 weeks. During the whole PSD period, JTW and estazolam were orally given to the rats respectively in the treating groups. Plasma concentration of lipopolysaccharide (LPS) which is the marker of gut-origin endotoxemia was examined. Intestinal morphology changes were observed by optical microscopy. The protein expression of occludin (Ocln) in the intestine was measured by immunofluorescence technique and Western blot. The expressions of circadian proteins cryptochromes (Cry1 and Cry2) in the intestine were also determined.</p><p><b>RESULTS</b>The treatment of JTW significantly decreased LPS level in OR rats with PSD (P<0.05). JTW also attenuated insomnia-induced intestinal injury like shorter, sparse and incomplete villus, wide gap between the villus, mucosal swelling and congesting (P<0.05). These changes were associated with the effect of JTW on up-regulating the expressions of Cry1 protein, Cry2 protein and Ocln protein in the intestine.</p><p><b>CONCLUSIONS</b>JTW has the beneficial effect on improving intestinal mucosal damage caused by PSD. The mechanism appears to be related to the modulation of the expressions of circadian proteins and Ocln protein in the intestine, thereby attenuating inflammation and improving insulin resistance in insomnia rats.</p>
RESUMO
Diabetic kidney disease (DKD) is a chronic renal microvascular complication associated with abnormal glucose metabolism, which is an important cause of end stage renal disease. Diabetes can damage the kidney through many ways, including renal vascular, glomerular, tubular, and renal interstitial damages. Therefore, a comprehensive treatment process must be taken for the treatment of DKD, and the selection of appropriate drugs has important significance in the treatment of DKD. Berberine has significant curative effect in the treatment of DKD, and the mechanism is related to the reduction of blood sugar, improvement of renal hemodynamics abnormality, regulation of blood lipid profile and the attenuation of systemic and local inflammation.
