ABSTRACT

Objective:To explore the interaction between hyperuricemia and gender on dyslipidemia in the elderly.Methods:A cross-sectional study. The permanent residents aged≥65 years in Kunshan City were selected by the cluster sampling method. The selected residents underwent physical examination and blood biochemical tests such as blood glucose, blood lipid, uric acid, hyaluronic acid, gamma glutamyltransferase and creatinine, and history of schistosomiasis infection was investigated. Multivariate logistic regression analysis was used to analyze the relationship between various factors and dyslipidemia. Synergy index (S), relative excess risk of interaction (RERI) and the attributable proportion due to interaction (AP) were used to evaluate the association between hyperuricemia and female interaction on dyslipidemia.. The dose-response relationship between serum uric acid level and dyslipidemia was analyzed by a restricted cubic spline regression model.Results:The prevalence of dyslipidemia in the elderly aged 65 years and obove was 31.9% (1 450/4 536), and it was 23.7% (517/2 180) and 39.6% (933/2 356) in men and women, respectively ( χ2=131.38, P<0.001). Multivariate regression showed that female, high waist circumference, overweight and obesity, hypertension, diabetes, low glomerular filtration rate, high gamma-glutamyltranspeptidase, high uric acid to creatinine ratio, low neutral to lymphocyte ratio were associated with dyslipidemia (all P<0.05). Additionally, additive interaction association was found between the dyslipidemia and advanced uric acid levels ( OR=1.09, 95% CI: 1.07-1.12) and female ( OR=1.12, 95% CI: 1.11-1.14), and the contribution rate of interaction effects was 19.8% (RERI=0.74, 95% CI: 0.06-1.42; AP=0.20, 95% CI: 0.04-0.36, S=1.37, 95% CI: 1.02-1.84). Non-linear dose response relationship was identified by the restricted cubic spline regression model between the continuously rising serum uric acid and dyslipidemia ( χ2=101.23, P<0.001). Conclusions:The proportion of dyslipidemia in elderly permanent residents is high. Demographics and physical measurement indicators comprehensively affected the prevalence of dyslipidemia. In addition, both hyperuric acid and female have additive interaction on dyslipidemia.

ABSTRACT

Objective@#To analyze the correlation of the sperm DNA fragmentation index (DFI) level with semen parameters and pregnancy outcomes of artificial insemination of the husband (AIH) in the cycle of intrauterine insemination (IUI).@*METHODS@#We collected the clinical data on 777 cases of IUI, including female clinical indicators, male semen parameters, sperm DFI and pregnancy outcomes. According to the DFI level, we divided the patients into three groups: DFI < 15%, 15% ≤ DFI < 30% and DFI ≥ 30%.@*RESULTS@#The sperm DFI level was significantly elevated with the increased age of the males (P = 0.002) and closely related to the total number of motile sperm (P = 0.002) and total sperm motility (P = 0.000) before treatment, as well as to sperm concentration (P = 0.000), total sperm motility (P = 0.001) and total number of progressively motile sperm (P = 0.000) after density gradient centrifugation. The rate of clinical pregnancy was decreased in the DFI ≥ 30% group. There were no statistically significant differences between sperm DFI and the rates of clinical pregnancy and abortion.@*CONCLUSIONS@#Male age significantly affects the sperm DFI level. Sperm DFI is closely related to sperm motility and total number of progressively motile sperm, but not to the rates of clinical pregnancy and abortion in patients undergoing IUI. IUI can be used as an effective method of assisted reproduction for male infertility./.

ABSTRACT

Objective:To analyze the safety of measles-containing vaccines (MCV) in Shanghai city. Methods:Adverse event following immunization cases related to measles attenuated live vaccine (MV), measles and rubella combined attenuated live vaccine (MR) and measles, mumps and rubella combined attenuated live vaccine (MMR) vaccination in Shanghai during 2011—2018 were collected from the National AEFI Surveillance System for epidemiological analysis. Results:A total of 15 055 MVC-related AEFI cases were reported, for an incidence of 139.74 per 100 000 doses. Among all MVC-related AEFI cases, the male to female ratio was 1.17∶1, and 12 068 (111.70 per 100 000 doses) were common reactions, with 1 050 from MV(64.66 per 100 000), 5 484 from MR(134.36 per 100 000)and 5 534 from MMR(108.60 per 100 000. Most of common reactions were fever (96.01 per 100 000), but 2 939 (27.20 per 100 000) were rare reactions, with 408 from MV (25.12 per 100 000), 1 983 from MR (48.59 per 100 000) and 548 from MMR (10.75 per 100 000). Most of rare reactions were allergic rash (25.00 per 100 000). Conclusion:MCV has a good safety profile but we should continue to strengthen MCV-related AEFI surveillance.

ABSTRACT

@#Background: The long waiting time for Tetralogy of Fallot (TOF) operation may potentially increase the risk of hypoxic insult. Therefore, the objective of this study is to determine the frequency of acute neurological complications following primary TOF repair and to identify the peri-operative risk factors and predictors for the neurological sequelae. Methods: A retrospective review of the medical and surgical notes of 68 patients who underwent TOF repair in Hospital Serdang, from January 2013 to December 2017 was done. Univariate and multivariate analyses of demographics and perioperative clinical data were performed to determine the risk for the development of acute neurological complications (ANC) among these patients. Results: ANC was reported in 13 cases (19.1%) with delirium being the most common manifestation (10/68, 14.7%), followed by seizures in 4 (5.9%) and abnormal movements in two patients (2.9%). Univariate analyses showed that the presence of right ventricular (RV) dysfunction, prolonged duration of inotropic support (≥7 days), prolonged duration of mechanical ventilation (≥7 days), longer length of ICU stays (≥7 days), and longer length of hospital stay (≥14 days), were significantly associated with the presence of ANCs (p<0.05). However, multivariate analyses did not show any significant association between these variables and the development of ANC (p>0.05). The predictors for the development of postoperative delirium were pre-operative oxygen saturation less than 75% (Odds Ratio, OR=16.90, 95% Confidence Interval, 95%CI:1.36, 209.71) and duration of ventilation of more than 7 days (OR=13.20, 95%CI: 1.20, 144.98). Conclusion: ANC following TOF repair were significantly higher in patients with RV dysfunction, in those who required a longer duration of inotropic support, mechanical ventilation, ICU and hospital stay. Low pre-operative oxygen saturation and prolonged mechanical ventilation requirement were predictors for delirium which was the commonest neurological complications observed in this study. Hence, routine screening for delirium using an objective assessment tool should be performed on these high-risk patients to enable accurate diagnosis and early intervention to improve the overall outcome of TOF surgery in this country

ABSTRACT

Aim To investigate the effects of overexpression of short-chain acyl-CoA dehydrogenase (SCAD) recombinant adenovirus on heart failure following myocardial infarction in rats, and to explore the relationship between SCAD and heart failure. Methods The rat model of heart failure following myocardial infarction was established by ligation of left anterior descending coronary artery (LAD). The SCAD recombinant adenovirus was injected into the apical wall. The experimental groups were divided into 6 groups; Sham + NS group, LAD + NS group, Sham + Ad-GFP group, Sham + Ad-SCAD group, LAD + Ad-GFP group and LAD + Ad-SCAD group. Systolic blood pressure (SBP) of tail artery was measured after surgery and the cardiac morphological changes were detected. The changes of SCAD mRNA expression, protein expression, enzyme activity, ATP content and free fatty acid content were examined. Results Compared with sham group, LAD + NS group showed heart failure significantly. Compared with LAD + NS group, SBP from LAD + Ad-SCAD group increased obviously after surgery, collagen deposition was apparently reduced and myocardial fibrosis was markedly improved. Compared with Sham + NS group, the SCAD mRNA, protein expression, enzyme activity and ATP content in LAD + NS group obviously decreased, and the contents of free fatty acids markedly increased. Compared with LAD + NS group, the above indicators of LAD + Ad-SCAD group were evidently reversed after treated with SCAD recombinant adenovirus. Conclusion Overexpression of SCAD recombinant adenovirus in heart can significantly improve heart failure caused by LAD.

ABSTRACT

OBJECTIVE@#To compare the clinical effect differences between "'s five-needle method" and routine acupoint selection on allergic rhinitis and asthma syndrome.@*METHODS@#A total of 210 patients with allergic rhinitis and asthma syndrome were randomly divided into an observation group (105 cases, 4 cases dropped off) and a control group (105 cases, 4 cases dropped off). The patients in the observation group were treated with "'s five-needling method", and the acupoints of Feishu (BL 13), Dazhui (GV 14), Fengmen (BL 12), Yintang (GV 29), Shangyingxiang (EX-HN 8) and Hegu (LI 4), etc. were selected; the patients in the control group was treated with routine acupuncture, and the acupoints of Feishu (BL 13), Zhongfu (LU 1), Taiyuan (LU 9), Dingchuan (EX-B 1), Danzhong (CV 17), Yintang (GV 29), Fengmen (BL 12) and Zusanli (ST 36), etc. were selected. The treatment in the two groups was given once a day, 6 times a week, for 4 weeks. The score of symptoms and signs was observed before and after treatment as well as 1 month, 2 months and 3 months after treatment. The forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF) and eosinophils in peripheral blood were measured before and after treatment in the two groups. After treatment, the clinical therapeutic effect was compared between the two groups.@*RESULTS@#The total effective rate was 98.0% (99/101) in the observation group, which was superior to 94.1% (95/101) in the control group (0.05), and the total score of symptoms and signs in the third month of follow-up in the control group was significantly increased (<0.05). After treatment, FEV1 and PEF in the two groups were increased (<0.01), eosinophil count in peripheral blood was decreased (<0.01), and the improvement in the observation group was greater than that in the control group (<0.01, <0.05).@*CONCLUSION@#"'s five-needle method" can improve the clinical symptoms and pulmonary function, reduce the count of eosinophils in peripheral blood in patients with allergic rhinitis and asthma syndrome, and the curative effect is better than routine acupuncture.

ABSTRACT

OBJECTIVE@#To investigate the correlation between soluble receptor for advanced glycation end products (sRAGE) level in the follicular fluid and ovarian responsiveness in non-PCOS patients undergoing controlled ovarian hyperstimulation.@*METHODS@#Ninety non-PCOS patients underwent IVF/ICSI using a short-acting long protocol for ovarian stimulation with a GnRH agonist. For each patient, the level of sRAGE in the follicular fluid was measured by enzyme linked immunosorbent assay (ELISA), and the data including the clinical baseline state, hormone level, number of oocytes obtained and the fertilization rate were collected.@*RESULTS@#Follicular fluid sRAGE level showed significant negative correlations with basal FSH level (=0.0036) and Gn dose ( 15) than in cases with oocytes obtained within the range of the target numbers (7-15) and below the target number (< 7) ( < 0.0001 and =0.0012, respectively).@*CONCLUSIONS@#Follicular fluid sRAGE level can reflect ovarian reserve function in non-PCOS patients, the number of oocytes obtained and the fertilization rate, and can thus predict ovarian responsiveness during controlled hyperstimulation in nonPCOS patients.

ABSTRACT

Objective@#To investigate the relationship between the serum anti-Müllerian hormone (AMH) level and semen parameters.@*METHODS@#We collected the data about 726 outpatients at the Male Infertility Clinic of Jinling Hospital from September 2015 to November 2016, including 72 with non-obstructive azoospermia, 123 with oligospermia, and 531 with normal sperm concentration. We obtained the semen volume, total sperm count, sperm concentration, sperm motility, the percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS), and the levels of serum AMH, inhibin B (INH-B), total testosterone (TT) and follicle - stimulating hormone (FSH) of the patients, analyzed the correlation of the serum AMH level with the other parameters, and compared the AMH level among different groups.@*RESULTS@#The serum AMH level was found to be correlated positively with the total sperm count (r = 0.227, P 0.05). There was a statistically significant difference in the serum AMH level among the patients with non-obstructive azoospermia, oligozoospermia, and normal sperm concentration ([6.33 ± 4.26] vs [8.26 ± 3.98] vs [9.8 ± 5.19] ng/ml, P <0.001).@*CONCLUSIONS@#Serum AMH is a biomarker reflecting the function of Sertoli cells and its level is significantly correlated with sperm concentration and motility, suggesting that AMH may be involved in spermatogenesis and sperm maturation.

ABSTRACT

Background: Diabetes Mellitus (DM), characterised by chronic hyperglycaemia, exposes patients to acute and chronic complications, such as hypoglycaemia and vascular complications, respectively. The latter is associated with the degree of glycaemic control. Glycated haemoglobin (HbA1c) indicates long-term glycaemic control of the preceding 2-3 months. The practice of self-monitoring blood glucose (SMBG) is essential for insulin-treated diabetic patients to achieve optimum glycaemic control and prevent hypoglycaemia. Aim: The study aimed to determine the SMBG practice and frequency and its association with HbA1c and factors in insulin-treated diabetic patients. Methods: This was a cross-sectional study of insulin-treated diabetic patients attending follow-up at the diabetic clinic of Hospital Serdang from April 2015 to August 2015. Consented eligible patients completed validated selfadministered questionnaires. Patients’ HbA1c results were obtained from the hospital information system. Results: Ninetyone of 137 (66%) patients practiced SMBG and 46 (34%) did not. Although 82% had seen diabetic nurses, 54% of patients did not alter their treatment accordingly. Neither the practice nor the frequency of SMBG was significantly associated with differences in HbA1c levels (p=0.334 and p=0.116 respectively). Ethnicity and household income significantly affected SMBG practice. The presence and frequency of hypoglycaemia significantly increased the likelihood of SMBG practice (p<0.001) and frequency (p<0.001). Conclusions: The prevalence of SMBG practice in diabetic patients on insulin was 66%. However, SMBG was not followed by proper treatment alteration in 54% of patients. There was no association between SMBG practice and frequency with good glycaemic control. Hypoglycaemia significantly affected the practice and frequency of SMBG.

ABSTRACT

Purpose: To determine if providing high dose anti‑oxidant vitamins and zinc treatment age‑related eye disease study (AREDS formulation) to patients with intermediate age‑related macular degeneration (AMD) aged 40–79 years from Singapore is cost‑effective in preventing progression to wet AMD. Methods: A hypothetical cohort of category 3 and 4 AMD patients from Singapore was followed for 5 calendar years to determine the number of patients who would progress to wet AMD given the following treatment scenarios: (a) AREDS formulation or placebo followed by ranibizumab (as needed) for wet AMD. (b) AREDS formulation or placebo followed by bevacizumab (monthly) for wet AMD. (c) AREDS formulation or placebo followed by aflibercept (VIEW I and II trial treatment regimen). Costs were estimated for the above scenarios from the providers’ perspective, and cost‑effectiveness was measured by cost per disability‑adjusted life year (DALY) averted with a disability weight of 0.22 for wet AMD. The costs were discounted at an annual rate of 3%. Results: Over 5400 patients could be prevented from progressing to wet AMD cumulatively if AREDS formulation were prescribed. AREDS formulation followed by ranibizumab was cost‑effective compared to placebo‑ranibizumab or placebo‑aflibercept combinations (cost per DALY averted: SGD$23,662.3 and SGD$21,138.8, respectively). However, bevacizumab (monthly injections) alone was more cost‑effective compared to AREDS formulation followed by bevacizumab. Conclusion: Prophylactic treatment with AREDS formulation for intermediate AMD patients followed by ranibizumab or for patients who progressed to wet AMD was found to be cost‑effective. These findings have implications for intermediate AMD screening, treatment and healthcare planning in Singapore.

ABSTRACT

<p><b>INTRODUCTION</b>Hepatitis B virus (HBV) reactivation has been reported in B-cell lymphoma patients with resolved hepatitis B (hepatitis B surface antigen [HBsAg]-negative and hepatitis B core antibody [HBcAb]-positive). This study aimed to assess HBV reactivation and hepatitis occurrence in diffuse large B-cell lymphoma (DLBCL) patients with resolved hepatitis B receiving rituximab-containing chemotherapy compared with HBsAg-negative/HBcAb-negative patients to identify risk factors for HBV reactivation and hepatitis occurrence and to analyze whether HBV reactivation and hepatitis affect the survival of DLBCL patients with resolved hepatitis B.</p><p><b>METHODS</b>We reviewed the clinical data of 278 patients with DLBCL treated with rituximab-containing therapy between January 2004 and May 2008 at Sun Yat-sen University Cancer Center, China. Predictive factors for HBV reactivation, hepatitis development, and survival were examined by univariate analysis using the chi-square or Fisher's exact test and by multivariate analysis using the Cox regression model.</p><p><b>RESULTS</b>Among the 278 patients, 165 were HBsAg-negative. Among these 165 patients, 6 (10.9%) of 55 HBcAb-positive (resolved HBV infection) patients experienced HBV reactivation compared with none (0%) of 110 HBcAb-negative patients (P = 0.001). Patients with resolved hepatitis B had a higher hepatitis occurrence rate than HBsAg-negative/HBcAb-negative patients (21.8% vs. 8.2%, P = 0.013). HBcAb positivity and elevated baseline alanine aminotransferase (ALT) levels were independent risk factors for hepatitis. Among the 55 patients with resolved hepatitis B, patients with elevated baseline serum ALT or aspartate aminotransferase (AST) levels were more likely to develop hepatitis than those with normal serum ALT or AST levels (P = 0.037, P = 0.005, respectively). An elevated baseline AST level was an independent risk factor for hepatitis in these patients. Six patients with HBV reactivation recovered after immediate antiviral therapy, and chemotherapy was continued. HBcAb positivity, HBV reactivation, or hepatitis did not negatively affect the survival of DLBCL patients.</p><p><b>CONCLUSIONS</b>DLBCL patients with resolved hepatitis B may have a higher risk of developing HBV reactivation and hepatitis than HBsAg-negative/HBcAb-negative patients. Close monitoring and prompt antiviral therapy are required in these patients.</p>

ABSTRACT

<p><b>INTRODUCTION</b>The rearrangement of the anaplastic lymphoma kinase (ALK) gene accounts for approximately 1%-6% of lung adenocarcinoma cases and defines a molecular subgroup of tumors characterized by clinical sensitivity to ALK inhibitors such as crizotinib. This study aimed to identify the relationship between ALK rearrangement and the clinicopathologic characteristics of non-small cell lung cancer (NSCLC) and to analyze the therapeutic responses of crizotinib and conventional chemotherapy to ALK rearrangement in NSCLC patients.</p><p><b>METHODS</b>A total of 487 lung cancer patients who underwent testing for ALK rearrangement in our department were included in this study. ALK rearrangement was examined by using fluorescence in situ hybridization (FISH) assay.</p><p><b>RESULTS</b>Among the 487 patients, 44 (9.0%) were diagnosed with ALK rearrangement by using FISH assay. In 123 patients with adenocarcinoma who were non-smokers and of a young age (≤ 58 years old), the frequency of ALK rearrangement was 20.3% (25/123). Short overall survival (OS) was associated with non-adenocarcinoma tumor type (P = 0.006), poorly differentiated tumors (P = 0.001), advanced-stage tumors (P < 0.001), smoking history (P = 0.008), and wild-type epidermal growth factor receptor (EGFR) (P = 0.008). Moreover, patients with poorly differentiated and advanced-stage tumors had a shorter time to cancer progression compared with those with well differentiated (P = 0.023) and early-stage tumors (P = 0.001), respectively.</p><p><b>CONCLUSIONS</b>ALK-rearranged NSCLC tends to occur in younger individuals who are either non-smokers or light smokers with adenocarcinoma. Patients with ALK rearrangement might benefit from ALK inhibitor therapy.</p>

ABSTRACT

Objective Glycodelin-A is one of glycoproteins secreted from endometrial epithelial cells , and it plays an im-portant role in embryo implantation , inhibition of reject reaction and pregnancy maintenance .Glycodelin-A will become an important potential marker in evaluating the endometrial receptivity and predicting the pregnancy outcome .The aim of this study was to investigate the correlation of glycodelin-A detected on the day of HCG and endometrial receptivity and the effects of glycodelin -A on the pregnancy outcome in the intrauterine insemination (IUI) period. Methods One hundred and seven woman patients with bilateral unobstruct-ed tubes and without endometrial lesions , endometrial polyps or intrauterine adhesions from Oct 2012 to Feb 2014 in our hospital were recruited in this study .Serum glycodelin-A in women receiving IUI on the day of HCG was measured by ELISA .Serum estradiol (E2), progesterone (P), and corpus luteum (LH) levels were measured by immunochemiluminometric assays .The condition of the endometrium was examined by transvaginalultrasonography . Results The serum glycodelin-A level on the day of HCG was higher in pregnant group [(1.47 ±0.38)ng/mL] than that in nonpregnant group ([0.62 ±0.13]ng/mL).The serum glycodelin-A level on the day of HCG was higher in endometrial thickness ≥7 mm group ([1.53 ±0.49]ng/mL) than endometrial thickness <7 mm group ([0.51 ±0.17]ng/mL). Conclusion The serum glycodelin-A level on the day of HCG may reflect endometrial receptivity to a cer-tain extent , which might have prognosis value for pregnancy following IUI .

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effect of morphine on male reproductive ability and its mechanisms in the rat model of morphine tolerance.</p><p><b>METHODS</b>Twenty male SD rats were equally randomized to groups I (control) and II (morphine tolerance). On the 1st day, the basic paw withdrawal thermal latency (PWTL) was obtained from all the rats followed by subcutaneous injection of morphine at 10 mg/kg and then calculation of the percentage of the maximal possible effect (MPE) at 30 min after administration. On the 2nd day, the rats of group I were injected subcutaneously with saline and those of group I with morphine at 10 mg/kg bid for 7 days. Then all the rats were killed after behavioral tests and their testes and epididymides harvested for sperm counting and determina- tion of the expressions of Bax and Caspase-3 by immunohistochemistry.</p><p><b>RESULTS</b>On the 1st day, no obvious differences were ob- served between the two groups in the basic PWTL or the percentage of MPE. On the 7th day, the percentage of MPE was significantly decreased in group II as compared with group I (P < 0.05), while the basic PWTL showed no marked difference between the two groups. Group II also exhibited a significantly reduced epididymal perm count (P < 0.05) and remarkably upregulated expressions of Bax and Caspase-3 in comparison with group I.</p><p><b>CONCLUSION</b>Morphine might increase testicular cell apoptosis and reduce sperm concentration by upregulating the expressions of Bax and Caspase-3 in the rat model of morphine tolerance.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Globozoospermia is mostly associated with homozygous deletion of the DPY19L2 gene. This study aimed to investigate the DPY19L2 gene mutation in a globozoospermia patient.</p><p><b>METHODS</b>We observed the sperm histomorphology of a patient with globozoospermia using Wright-Giemsa's staining and transmission electron microscopy, detected the mutation of the DPY19L2 gene by PCR amplification and DNA sequencing, and compared the findings with the sequences issued in the Genbank.</p><p><b>RESULTS</b>Wright-Giemsa's staining showed that all the spermatozoa were round-headed and lacked the acrosome, with the head nucleus darkly, fully and densely stained. Transmission electron microscopy revealed larger round sperm heads, with an even layer of unit membrane surrounding the nuclei and dispersed cytoplasmic vacuoles but no acrosomal structure. No DPY19L2 gene mutation was found by PCR amplification and DNA sequencing.</p><p><b>CONCLUSION</b>No homozygous mutation of the DPY19L2 gene was found in the globozoospermia patient, and therefore some other disease-causing genes might be involved.</p>
