ABSTRACT
Aim To explore the effect of kaempferol-7- 0-neohesperidoside (K70N) against prostate cancer (PCa) and the underlying mechanism. Methods The effect of K70N on the proliferation of PCa cell lines PC3, DU145, C4-2 and LNCaP was detected using CCK8 assay. The effect of K70N on migration ability of DU145 cells was determined by wound healing assay. The targets of K70N and PCa were screened from SuperPred and other databases. The common targets both related to K70N and PCa were obtained from the Venny online platform, a protein-protein interaction network (PPI) was constructed by the String and Cyto- scape. Meanwhile, the GO and KEGG functional enrichment were analyzed by David database. Then, a "drug-target-disease-pathway" network model was constructed. Cell cycle of PCa cells treated with K70N was analyzed by flow cytometry. The expressions of cycle-associated proteins including Skp2, p27 and p21 protein were detected by Western blot. Molecular docking between Skp2 and K70N was conducted by Sybyl X2. 0. Results K70N significantly inhibited the proliferation and migration of PCa cells. A total number of 34 drug-disease intersection targets were screened. The String results showed that Skp2 and p27, among the common targets, were the key targets of K70N for PCa treatment. Furthermore, GO and KEGG functional en-richment indicated that the mechanism was mainly related to the cell cycle. Flow cytometry showed that K70N treatment induced cell cycle arrest at the S phase. Compared with the control group, the protein expression level of Skp2 was significantly down-regulated, while the protein expression levels of p27 and p21 were up-regulated. The network molecular docking indicated that the ligand K70N had a good binding ability with the receptor Skp2. Conclusions K70N could inhibit the proliferation and migration of PCa cells, block the cell cycle in the S phase, which may be related to the regulation of cell cycle through the Skp2- p27/p21 signaling pathway.
ABSTRACT
Aim To investigate the sensitization effect of total flavonoids of litchi seed (TFLS) to paclitaxel (PTX) on prostate cancer paclitaxel resistance (PCa-Txr) cells and the synergistic inhibitory effect of TFLS combined with PTX. Methods CCK-8 method was carried out to detect the inhibitory effect of TFLS and PTX on PCa-Txr cells as well as corresponding parental cells. PCa-Txr cells were either pre-treated or simultaneously treated with low cytotoxic dose of TFLS to observe the sensitivity of PCa-Txr cells to PTX. The synergistic inhibitory effect of TFLS combined with PTX on the proliferation of PCa-Txr cells were observed according to the method recommended by Chou T C. Combination index (CI) was used to determine whether TFLS and PTX had synergistic inhibitory effect. Results TFLS significantly inhibited the proliferation of PCa-Txr cells and parental cells in a certain time- and dose-dependent manner. The low dose of TFLS pre-treated or treated with PTX simultaneously failed to increase the sensitivity of PTX on PCa-Txr cells. TFLS combined with PTX significantly inhibited the proliferation of PCa-Txr cells with CI value less than one. Conclusions TFLS inhibits the proliferation of PCa-Txr cells, while TFLS combined with PTX has synergistic inhibitory effect on PCa-Txr cells. However, TFLS fails to increase the sensitivity of PCa-Txr cells to PTX.
ABSTRACT
OBJECTIVE@#To establish a congenital chloride diarrhea (CCD)-associated SLC26A3 c.392C>G (p.P131R) polymorphism-expressing cell model, and to investigate its biological function.@*METHODS@#The sequence of the SLC26A3 gene in GenBank was used to design the upstream and downstream single-guide RNA (sgRNA) that could specifically recognize the 392 locus of the SLC26A3 gene, and the sgRNA was mixed with the pSpCas9-puro vector after enzyme digestion to construct an eukaryotic recombinant expression plasmid (pSpCas9-SLC26A3). Caco-2 cells were transfected with the recombinant plasmid and synthesized single-stranded DNA oligonucleotides (ssODNs), and Taqman genotyping assay and Sanger sequencing were used to identify the expression of SLC26A3 c.392C>G (p.P131R) in Caco-2 cells. Wild-type Caco-2 cells were selected as normal control group and the Caco-2 cells with successful expression of SLC26A3 c.392C>G (p.P131R) was selected as P131R group. Both groups were treated with 100 ng/mL tumor necrosis factor-α (TNF-α), and then the normal control group was named as TNF-α group, and the P131R group was named as TNF-α+P131R group. Electric cell-substrate impedance sensing (ECIS) assay was used to evaluate the change in the monolayer barrier function of intestinal epithelial cells in the above four groups, and Western blot was used to measure the change in the expression of SLC26A3 protein in the normal control group and the P131R group.@*RESULTS@#The eukaryotic recombinant expression plasmid (pSpCas9-SLC26A3) was successfully constructed. Both Taqman genotyping assay and Sanger sequencing confirmed the successful establishment of the Caco-2 cell model of SLC26A3 c.392C>G (p.P131R) expression. ECIS assay showed that compared with the normal control group, the P131R group had a significant increase in the monolayer permeability of intestinal epithelial cells (PG (p.P131R) can reduce the expression of SLC26A3 protein, increase the monolayer permeability of intestinal epithelial cells, and thus lead to diarrhea.

<p><b>OBJECTIVES</b>To explore the association of sleep duration with obesity among children in urban areas of China.</p><p><b>METHODS</b>A total of 6 576 children (3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China. A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level. The height, weight, waist circumference (WC) and percentage of body fat (%BF, as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures. The information on demography, lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.</p><p><b>RESULTS</b>The average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age (P < 0.05). The sleep duration was negatively associated with body mass index (BMI) and WC in both boys and girls after adjustment for confounders (beta value -0.23 and -0.82 for boys, -0.24 and -0.91 for girls, respectively, P < 0.01). However, no significant association of sleep duration with %BF was found. Children who slept less than 9.0 h per night had a higher risk for overweight and obesity (OR = 1.29, 95% CI: 1.01, 1.64) and abdominal obesity (OR=1.38, 95% CI: 1.04, 1.83) as compared with those who slept for 10.0-10.9 h.</p><p><b>CONCLUSIONS</b>Short sleep duration is associated with obesity. It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life.</p>

<p><b>OBJECTIVE</b>To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China.</p><p><b>METHODS</b>A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire.</p><p><b>RESULTS</b>SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)].</p><p><b>CONCLUSIONS</b>Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.</p>

<p><b>BACKGROUND</b>Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, and SVA with discrete membranous subaortic stenosis is even rarer. The aim of the study was to make sure the incidence of SVA with discrete membraneous subaortic stenosis in SVA and their surgical results. We retrospectively analyzed 234 patients receiving surgical repair of SVA and reported the incidence of ventricular septal defect, aortic regurgitation, and discrete membranous subaortic stenosis. We also reported seven cases of SVA combined with discrete membranous subaortic stenosis and their surgical results.</p><p><b>METHODS</b>Between January 1999 and December 2009, seven patients of SVA with discrete membranous subaortic stenosis underwent surgical repair of SVA and resection of subaortic discrete membrane. There were six male and one female patients. The mean age was (33.71 ± 13.25) years (range 16 - 52 years). Associated cardiovascular lesions were aortic regurgitation (n = 7), ventricular septal defect (n = 5), coarctation of aorta (n = 1), bicuspid aortic valve (n = 1), patent ductus arteriosus (n = 1), and aortic valve stenosis (n = 1). The aortic valve was replaced in four patients and valvuloplasty was done in three. The other co-existing anomalies were corrected at the same time. All the seven patients were followed up from 18 to 125 months (mean (63.14 ± 39.54) months). Among 234 SVA patients who underwent surgical repair, the number of cases with coexisting ventricular septal defect, aortic regurgitation, and discrete membranous subaortic stenosis was 129, 108, and 7, respectively.</p><p><b>RESULTS</b>There was neither early death after operation nor late death during the follow-up period. All the seven patients were in the New York Heart Association (NYHA) functional classes I and II. There was no recurrence of discrete subaortic membrane during the follow-up period. The incidence of ventricular septal defect, aortic valve incompetence, and discrete membranous subaortic stenosis among 234 SVA patients was 55.13%, 46.15%, and 2.99%, respectively.</p><p><b>CONCLUSIONS</b>Surgical repair of SVA with discrete membranous subaortic stenosis showed good mid-term results. Resection of discrete subaortic membrane should be done actively while repairing SVAs. Long-term results need to be followed up.</p>

<p><b>BACKGROUND</b>Cryopreserved conduit valved homografts (CVH) have been widely used in surgical treatment of cardiac disease. This study aimed to determine the extent of host cell ingrowth and the durability and immunogenicity of CVH, and to compare the performance of CVH stored at 4°C and CVH cryopreserved in liquid nitrogen at -196°C.</p><p><b>METHODS</b>Heterotopic transplants of canine CVH stored at 4°C (n = 14) and cryopreserved in liquid nitrogen (n = 14) were made onto the abdominal aorta of recipient dogs. Animals were sacrificed at 7 and 15 days and at 1, 3, 6, 9, and 12 months after transplantation to excise the implanted CVHs. Tissue DNA extraction and quantitative polymerase chain reaction (PCR) were performed to calculate the ratio of donor cells and host cells in the CVH. The tissue viability of CVH after implantation was analyzed by detecting alkaline fibroblast growth factor 2 (FGF-2) using immunohistochemical staining and by observation under transmission electron microscope and scanning electron microscope.</p><p><b>RESULTS</b>All the animals survived and recovered well. There were few repopulating host cells (0.04% - 0.83%) in the implanted CVH at 7 or 15 days. The ratio of ingrowing host cells into the CVH continued rising after implantation and reached 40% - 47% in the 12th month postoperation. Histology, transmission electron microscopy and FGF-2 immunohistochemical staining indicated that fibroblasts and the host's endothelial cells were the main cellular elements invading the CVH. There were no significant differences in results between CVH stored at 4°C and CVH cryopreserved in liquid nitrogen.</p><p><b>CONCLUSIONS</b>Host cells growing into CVH are very important for maintaining the long-term structure and function of the implanted CVH. There is no significant difference between CVH storing at 4°C or in liquid nitrogen in regard to the ingrowth of host cells or of morphologic features after CVH allografting.</p>

<p><b>BACKGROUND</b>Reconstructive surgery is the primary goal in pediatric patients with valve disease. However, in cases with irreparable valve lesions, valve replacement is the only option. This study aimed to retrospectively analyze the clinical experience of heart valve prosthesis replacement in children.</p><p><b>METHODS</b>Between January 1990 and July 2009, 35 pediatric patients (16 boys, 19 girls) underwent mechanical valve replacement in Shandong University Qilu Hospital. The ages ranged from 2.5 to 14 years (mean, (8.8 ± 3.8) years) and body weight varied from 11 to 37 kg (mean, (22.1 ± 5.2) kg). Mechanical valve replacement was performed because of congenital heart disease in 23 patients, rheumatic disease in ten patients and infective endocarditis in two patients. St. Jude bileaflet mechanical valves were implanted in all the 35 patients including mitral valve replacement (MVR) in 18, aortic valve replacement (AVR) in 12, tricuspid valve replacement (TVR) in two, AVR and MVR in two and MVR and TVR in one. The size of the prostheses ranged between 19 and 27 mm. All patients received long-term anticoagulation treatment with sodium warfarin, aiming to maintain an international normalized ratio between 1.5 to 2.0. Follow-up was performed in all the patients with a total follow-up of 119.4 patient-years.</p><p><b>RESULTS</b>The operative mortality was 8.57% (3/35). One patient, who underwent cardiac debridement and AVR, died 2 hours after being admitted to the intensive care unit because of severe low cardiac output syndrome and ventricular fibrillation. Two patients died of cardiogenic shock and renal failure during initial hospitalization after the operation. One patient who received replacement of a tricuspid valve developed complete heart block requiring temporary pacing and recovered sinus rhythm 4 days later. Thirty-two patients survived and their cardiac function was in New York Heart Association (NYHA) class I to class II when discharged. Late events included hemorrhage and endocarditis. Two patients required reoperation. No late deaths occurred during the follow-up.</p><p><b>CONCLUSIONS</b>Mechanical valve replacement remains an acceptable treatment option in children when the valve reparation is impossible or unsuccessful. The operative mortality and incidence of any valve-related events such as endocarditis, reoperation, thromboembolism or anticoagulation-related bleeding are acceptable.</p>

<p><b>BACKGROUND</b>Kawasaki disease (KD) is the leading cause of pediatric ischemic heart disease. The incidence of serious coronary sequelae is low and about 2% - 3% of patients with KD, but once myocardial infarction occurs in children, the mortality is quite high and 22% at the first infarction.This study aimed to evaluate the efficacy of coronary artery bypass grafting (CABG) in patients with KD.</p><p><b>METHODS</b>Eight patients with a history of KD underwent CABG between October 1997 and July 2005. The number of bypass grafts placed was 2 to 4 per patient (mean 2.5 +/- 0.8). Various bypass grafts were used in patients, i.e. the left internal mammary artery (LIMA) in 3 patients, bilateral internal mammary artery (IMA) in 2 patients, LIMA plus gastroepiploic artery (GEA) in 1 patient and total saphenous vein grafts (SVGs) in 2 patients. The combined procedures included ventricular aneurysmectomy in 1 patient, mitral valve plasty in 1 and right coronary aneurysmectomy in 1. One patient was not able to wean from cardiopulmonary bypass (CPB), after being supported with intra-aortic balloon pump (IABP), the patient was weaned from CPB successfully.</p><p><b>RESULTS</b>One patient died of low cardiac output syndrome and acute renal failure 19 days after operation. Other patients recovered and were discharged uneventfully. During the follow-up that ranged from 3 to 57 months (mean 27 months), clincal angina disappeared or improved. Cardiac function was in Class I - II (NYHA).</p><p><b>CONCLUSION</b>CABG is a safe and effective procedure for Kawasaki coronary artery disease. However long-term results need to be followed up.</p>

<p><b>OBJECTIVE</b>To identify the relationship of adiponectin and the components of metabolic syndrome (MS).</p><p><b>METHODS</b>Cluster random sampling was applied in two districts of Shanghai. Two communities were selected. After investigating and physical examination, 235 MS subjects were obtained. Correlation analysis and principle components regression analysis were used to analyze the relationship between adiponectin and components of MS (waist circumference, blood pressure, blood glucose and lipid).</p><p><b>RESULTS</b>Adiponectin in male was (2.82 +/- 1.73) microg/ml, lower than in female [(5.12 +/- 3.51) microg/ml] with statistical difference (Z = -5.25, P = 0.00). Adiponectin levels [(4.38 +/- 3.23) microg/ ml] correlated with abdominal obesity, including waist circumference [(93.37 +/- 7.76) cm] (r(s) = - 0.18, t(r) = -2.79, P = 0.01) and waist hip ratio (0.91 +/- 0.05) (r(s) = -0.28, t(r) = -4.44, P = 0.00), but did not correlate significantly with body mass index (BMI) [(26.85 +/- 3.10) kg/m2] (r(s) = -0.10, t(r) = - 1.45, P = 0. 15). Adiponectin correlated negatively with insulin resistance related indexes, including fasting glucose [(5.48 +/- 1.72) mmol/L] (r(s) = -0.13, t(r) = -2.00, P = 0.05), fasting insulin [(11.52 +/- 5.34) mU/L] (r(s) = -0. 15, t(r) = - 2.31, P = 0.02), homeostasis model assessment of insulin resistance (HOMA-IR) (2.90 +/- 2.07) (r(s) = -0.17, t(r) = -2.63, P = 0.01) and triglyceride [(2.11 +/- 1.24) mmol/L] (r(s) = -0.24, t(r) = -3.77, P = 0.00). The correlations were not observed between adiponectin with total cholesterol [(5.01 +/- 1.19) mmol/L] ( r(s) = -0.05, t(r) = -0.78, P = 0.44), high density lipoprotein-cholesterol (HDL-C) [(1.21 +/- 0.32) mmol/L] (r(s) = 0.06, t(r) = 0.93, P = 0.36), systolic blood pressure [(131.40 +/- 14.93) mm Hg, 1 mm Hg = 0.133 kPa] (r(s) = -0.02, t(r) = -0.34, P = 0.73) and diastolic blood pressure [(86.77 +/- 9.14)mm Hg] (r(s) = -0.02, t(r) = -0.27, P = 0.78).</p><p><b>CONCLUSION</b>Adiponectin should correlate negatively with abdominal obesity and insulin resistance, but not directly correlate with blood pressure in MS.</p>

<p><b>OBJECTIVE</b>To evaluate effectiveness of surgical correction in patients with anomalous origin of the coronary artery from the pulmonary artery.</p><p><b>METHODS</b>Between April 1999 and August 2005, 12 patients with anomalous origin of the coronary artery from the pulmonary artery underwent surgical correction. There were 8 patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), and 4 patients with anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA). Eight patients underwent direct aortic reimplantation, and 4 patients underwent a Takeuchi procedure (intrapulmonary artery baffle with an autologous pericardial patch). Simultaneous mitral annuloplasty was performed in 7 patients of ALCAPA with moderate and severe mitral regurgitation. One patient of ARCAPA was associated with an atrial septal defect (ASD) which was closed with an amplatzer septal occluder through right atrium under transesophageal echocardiography (TEE) without CPB.</p><p><b>RESULTS</b>There were neither early and late deaths nor postoperative complications. Follow-up of all patients ranged from 7 to 83 months (mean, 32 +/- 24 months). The left ventricular function after operation improved from a preoperative fractional shortening (FS) of 0.21 +/- 0.09 to 0.35 +/- 0.06 (P = 0.006) for patients with ALCAPA. Preoperative mitral regurgitation decreased in 7 patients of ALCAPA after mitral annuloplasty at the follow-up. All patients were doing well and their exercise tolerance improved to normal. They were free from symptoms.</p><p><b>CONCLUSIONS</b>Reestablishment of a two-coronary system is necessary for patients with anomalous origin of the coronary artery from the pulmonary artery. The left ventricular function improved after 2-coronary repair. We recommend that the simultaneous mitral annuloplasty should be performed at the time of operation for patients who have moderate and severe mitral regurgitation with ALCAPA. Surgical correction of ARCAPA and ARCAPA show good early and mid-term results, long-term results need to be followed up.</p>

<p><b>OBJECTIVE</b>To analyze the effects of cholesterol ester transfer protein (CETP) Taq1B polymorphism on the response of serum HDL-C to dietary factors in hyperlipidemia patients.</p><p><b>METHODS</b>All 141 hyperlipidemia residents in a community in Shanghai were investigated by a 3-day diet questionnaire. The serum lipids were analyzed, and the polymorphism of CETP gene was detected by PCR-RFLP method. The correlation between dietary factors and serum HDL-C in different genotype was analyzed when considering the effects of sex, age and body mass index.</p><p><b>RESULT</b>The HDL-C of hyperlipidemia patients was affected by dietary factors and CETP gene Taq1B polymorphism. The strength of the correlation between dietary factors and serum HDL-C was different among the genotype groups. The relation was shown closer in B(2)B(2) subjects than in B(1)B(1).</p><p><b>CONCLUSION</b>The Taq1B CETP gene polymorphism should be a strong determinant of HDL-C in hyperlipidemia patients, and might contribute to the heterogeneity in HDL-C response to dietary intervention.</p>

<p><b>OBJECTIVE</b>To investigate the prevention of hepatolithiasis and biliary stricture post choledochojejunostomy using choledochoscopy technique and evaluate feasibility and efficacy of choledochojejunostomy and artificial valve of efferent loop in preventing reflux.</p><p><b>METHODS</b>To analyze the data of 47 patients with hepatolithiasis who had been operated with Roux-en-Y cholangiojejunostomy and artificial valve of efferent loop to prevent bilio-intestinal regurgitation. Of the patients, 19 were marked with silver nip at the jejunum export of bilio-intestinal anastomosis. The regurgitation, recurrence, anastomotic stricture and their managements after the surgery were investigated.</p><p><b>RESULTS</b>The bilio-intestinal regurgitation were found in 32 cases (32/47, 68.1%), it suggested that artificial valve could not prevent bilio-intestinal regurgitation efficiently. Two cases of hepatolithiasis recurred and were cured by sinus tract placement with the aid of silver nip mark under choledochoscope instead of re-operation. Of the 6 cases with anastomotic stricture, 5 cases were treated successfully with stone extraction, biliary stent dilatation under the percutaneous transhepatic cholangioscopy (PTCS) and the other one case died.</p><p><b>CONCLUSIONS</b>Silver nip mark provides safe and simple path for the cholangioscopy, it made the treatment of the recurrent biliary stricture and stone safe and brief, made the cholangioscopy play more important role in the hepatolithiasis, residual stone and biliary stricture. PTCS is mini-invasive, safe, simple and effective.</p>

<p><b>OBJECTIVE</b>To evaluate the effect of reduction aortoplasty for dilatation of the ascending aorta in patients with aortic valve disease.</p><p><b>METHODS</b>Between February 1998 and May 2004, 23 patients with aortic valve disease and dilatation of the ascending aorta underwent reduction aortoplasty in combination with aortic valve replacement. The diameter of the ascending aorta was measured before and early after surgery and then later between 4 and 78 months [mean (36 +/- 25) months] postoperatively using echocardiography.</p><p><b>RESULTS</b>The reduction aortoplasty decreased the diameter of the aorta from (4.8 +/- 0.5) cm preoperatively to (3.6 +/- 0.4) cm early after surgery (P < 0.01). During follow-up, the diameter of aorta increased from (3.6 +/- 0.4) cm early after surgery to (3.7 +/- 0.4) cm after a mean follow-up of (36 +/- 25) months (P < 0.05).</p><p><b>CONCLUSION</b>Reduction aortoplasty shows good mid-term results in patients with aortic valve disease and dilatation of the ascending aorta. Long-term results need to be followed up.</p>
