Objective: To examine the short-term curative effect with minimally invasive right infra-axillary thoracotomy for transaortic modified Morrow procedure. Methods: The clinical data of 60 patients who underwent video-assisted thoracoscopic transaortic modified Morrow procedure from August 2021 to August 2022 at Department of Cardiovascular Surgery, Zhejiang Provincial People's Hospital were retrospectively analyzed. There were 31 males and 29 females, with the age (M (IQR)) of 54.0(22.3) years (range: 15 to 71 years). The echocardiography confirmed the diagnosis of moderate mitral regurgitation in 30 patients, and severe mitral regurgitation in 13 patients. Systolic anterior motion (SAM) was present preoperatively in 54 patients. All 60 patients underwent transaortic modified Morrow procedure through a right infra-axillary thoracotomy using femorofemoral cardiopulmonary bypass. Surgical procedures mainly included transverse aortic incision, exposure of left ventricular outflow tract (LVOT), septal myectomy, and correction of the abnormal mitral valve and subvalvular structures. Results: All 60 patients underwent the programmatic procedures successfully without conversion to full sternotomy. The cardiopulmonary bypass time was (142.0±32.1) minutes (range: 89 to 240 minutes), while the cross-clamp time was (95.0±23.5) minutes (range: 50 to 162 minutes). The patients had a postoperative peak LVOT gradient of 7.0 (5.0) mmHg (range: 0 to 38 mmHg) (1 mmHg=0.133 kPa). A total of 57 patients were extubated on the operating table. The drainage volume in the first 24 h was (175.9±57.0) ml (range: 60 to 327 ml). The length of intensive care unit stay was 21.0 (5.8)h (range: 8 to 120 h) and postoperative hospital stay was 8 (5) days (range: 5 to 19 days). The postoperative septal thickness was 11 (2) mm (range: 8 to 14 mm). All patients had no iatrogenic ventricular septal perforation or postoperative residual SAM. The patients were followed up for 4 (9) months (range: 1 to 15 months), and none of them needed cardiac surgery again due to valve dysfunction or increased peak LVOT gradient during follow-up. Conclusion: Using a video-assisted thoracoscopic transaortic modified Morrow procedure through a right infra-axillary minithoracotomy can provide good visualization of the LVOT and hypertrophic ventricular septum, ensure optimal exposure of the mitral valve in the presence of complex mitral subvalvular structures, so that allows satisfactory short-term surgical results.

OBJECTIVE: To explore the protective effect and the underlying mechanism of Hu-Lu-Ba-Wan (, HLBW) on the testis of diabetic rats. METHODS: Twenty-four male Wistar rats (160-180 g) were randomly divided into 3 groups according to a random number table, including a control group (n=8), diabetic group (n=8), and HLBW group (n=8). Diabetic rat model was established by high-fat-diet administration and single intravenous injection of streptozotocin (26 mg/kg). Then HLBW granule was administrated for 12 weeks. Fasting blood glucose and insulin levels as well as serum total testosterone level and testicular testosterone content were examined. Oxidative stress markers in both serum and testis were tested. Meanwhile, testicular morphology was observed under hematoxylin and eosin (HE) and the ultrastructure of Leydig cell was observed by electron microscope. The superoxide anion level was detected by DHE, and TUNEL-positive cells of testis was evaluated by TUNEL assay. The gene and protein expression of protein kinase C (PKCα), phosphorylated PKCα (P-PKCα) and P47phox in testicular tissues were determined by quantitative RT-PCR analysis and Western bolt analysis. RESULTS: Compared with the diabetic group, HLBW treatment significantly reduced the fasting glucose levels and increased the levels of fasting insulin and testosterone in serum (P<0.01). HLBW administration also reduced the levels of reactive oxygen species (ROS) in plasma and alleviated the damage of oxidative stress in the testis of diabetic rats. Additionally, HLBW down-regulated the protein and mRNA levels of PKCα, P-PKCα and P47phox in testicular tissues. CONCLUSION HLBW may attenuate the oxidative stress in the testis of diabetic rats via PKCα /NAPDH oxidase signaling pathway.

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.

OBJECTIVETo explore the effect and mechanism of Jiaotai Pill (, JTW) on intestinal mucosal damage in rats with chronic partial sleep deprivation (PSD).

METHODSObesity 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.

RESULTSThe 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.

CONCLUSIONSJTW 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.

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.

The polymorphisms of thyroid stimulating hormone receptor (TSHR) intron 1 rs179247 and rs12101255 have been found to be associated with Graves' disease (GD) in genetic studies. In the present study, we conducted a meta-analysis to examine this association. Two reviewers systematically searched eligible studies in PubMed, Web of Science, Embase and China Biomedical Literature Database (CBM). A meta-analysis on the association between GD and TSHR intron 1 rs179247 or rs12101255 was performed. The odd ratios (OR) were estimated with 95% confidence interval (CI). Meta package in R was used for the analyses. Seven articles (13 studies) published between 2009 and 2014, involving 5754 GD patients and 5768 controls, were analyzed. The polymorphism of rs179247 was found to be associated with an increased GD risk in the allele analysis (A vs. G: OR=1.40, 95% CI=1.33-1.48) and all genetic models (AA vs. GG: OR=1.94, 95% CI=1.73-2.19; AA+AG vs. GG: OR=1.57, 95% CI=1.41-1.74; AA vs. AG+GG: OR=1.54, 95% CI=1.43-1.66). The site rs12101255 also conferred a risk of GD in the allele analysis (T vs. C: OR=1.50, 95% CI=1.40-1.60) and all genetic models (TT vs. CC: OR=2.22, 95% CI=1.92-2.57; TT+TC vs. CC: OR=1.66, 95% CI=1.50-1.83; TT vs. TC+CC: OR=1.74, 95% CI=1.53-1.98). Analysis of the relationship between rs179247 and Graves' ophthalmopathy (GO) showed no statistically significant correlation (A vs. G: OR=1.02, 95% CI=0.97-1.07). Publication bias was not significant. In conclusion, GD is associated with polymorphisms of TSHR intron 1 rs179247 and rs12101255. There is no association between rs179247 SNPs and GO.

Intestinal tight junction is an important part of the small intestinal mucosa barrier. It plays a very significant role in maintaining the intestinal mucosal permeability and integrity, preventing the bacterial endotoxin and toxic macromolecular substances into the body so as to keep a stable internal environment. Numerous studies have shown that intestinal mucosal barrier dysfunction is closely related to the development of diabetes. Therefore, protecting intestinal tight junction and maintaining the mucosal barrier have great significance in the prevention and treatment of diabetes. The effect of berberine in diabetes treatment is obvious. However, the pharmacological study found that the bioavailability of berberine is extremely low. Some scholars put forward that the major site of pharmaceutical action of berberine might be in the gut. Studies have shown that berberine could regulate the intestinal flora and intestinal hormone secretion, protect the intestinal barrier, inhibit the absorption of glucose, eliminate the intestinal inflammation and so on. Recently studies have found that the hypoglycemic effect of berberine is likely to relate with the influence on intestinal tight junction and the protection of mucosal barrier. Here is the review about the association between intestinal tight junction barrier dysfunction and diabetes, and the related hypoglycemic mechanism of berberine.

Diabetes is seriously hazards to human health and its pathogeneses are not clear. Recent studies show that the imbalance of intestinal flora and the development of diabetes are closely related. Appropriate bacteria can improve blood sugar disorder. Treating diabetes from the theory of Pi-Wei is effective. Regulating intestinal flora has become a new pathway for treating diabetes from the theory of Pi-Wei. On the basis of intestinal flora, authors discussed the treatment of diabetes from Pi and Wei.

OBJECTIVETo investigate the effects of berberine (BBR) and cinnamic acid (CA), the main active components in Jiaotai Pill (, JTP), on palmitic acid (PA)-induced intracellular triglyceride (TG) accumulation in NIT-1 pancreatic β cells.

METHODSCells were incubated in culture medium containing PA (0.25 mmol/L) for 24 h. Then treatments with BBR (10 μmol/L), CA (100 μmol/L) and the combination of BBR and CA (BBR+CA) were performed respectively. Intracellular lipid accumulation was assessed by Oil Red O staining and TG content was measured by colorimetric assay. The expression of adenosine monophosphate-activated protein kinase (AMPK) protein and its downstream lipogenic and fatty acid oxidation genes, including fatty acid synthase (FAS), acetyl-coA carboxylase (ACC), phosphorylation acetyl-coA carboxylase (pACC), carnitine acyl transferase 1 (CPT-1) and sterol regulating element binding protein 1c (SREBP-1c) were determined by Western blot or real time polymerase chain reaction.

RESULTSPA induced an obvious lipid accumulation and a significant increase in intracellular TG content in NIT-1 cells. PA also induced a remarkable decrease in AMPK protein expression and its downstream targets such as pACC and CPT-1. Meanwhile, AMPK downstream lipogenic genes including SREBP-1c mRNA, FAS and ACC protein expressions were increased. Treatments with BBR and BBR+CA, superior to CA, significantly reversed the above genes changes in NIT-1 pancreatic β cells. However, the synergistic effect of BBR and CA on intracellular TG content was not observed in the present study.

CONCLUSIONIt can be concluded that in vitro, BBR and BBR+CA could inhibit PA-induced lipid accumulation by decreasing lipogenesis and increasing lipid oxidation in NIT-1 pancreatic β cells.
