ABSTRACT

Objective:To investigate the correlation between early renal impairment markers in urine and elevated serum homocysteine.Methods:Clinical data of serum homocysteine (Hcy) and early renal injury markers in urine of the health examination population from the Physical Examination Center of Peking University Third Hospital from January 2019 to May 2020 were retrospectively analyzed (1133 cases). The previous medical history, age, sex, blood pressure, body mass index (BMI) of the subjects were collected. Early urine kidney injury markers, including urine microalbumin (U-mALB), urinary N-acetyl-β-D-glucosaminidase (NAG), urinary albumin to creatinine ratio (UACR), and serum renal function, liver function, blood lipid, myocardial enzyme and glycosylated hemoglobin (HbA 1C), etc. were also collected. Those with incomplete previous history, general information, biochemical indexes and decreased estimated glomerular filtration rate (eGFR) were excluded, and 969 cases were included. The included subjects were divided into the normal group (?15 μmol/L) and the elevated group (≥15 μmol/L) according to Hcy levels, the indexes with significant difference between the two groups were included as independent variables, and the multivariate logistic regression was used to explore the influence factors of Hcy elevation. Results:The male ratio, the incidence of increased U-mALB, NAG and UACR were significantly higher in the elevated group than those in the normal Hcy group (93.4% vs 50.6%, 16.4% vs 8.0%, 23.0% vs 14.0%, 13.9% vs 7.9%) (all P<0.05). Systolic blood pressure, diastolic blood pressure, serum uric acid, calcium, alanine aminotransferase (ALT) and lactate dehydrogenase in the elevated group were higher than those in the normal group [(127.5±15.4) vs (121.9±16.2) mmHg (1 mmHg=0.133 kPa), (78.6±9.3) vs (76.0±11.0) mmHg, (385.9±86.0) vs (335.7±88.2) μmol/L, (2.392±0.086) vs (2.366±0.092) mmol/L, (27.8±21.0) vs (23.8±20.2) U/L, (198.3±28.4) vs (192.2±31.2) U/L] (all P<0.05), while high density lipoprotein cholesterol (HDL-C), serum phosphorus were lower than those in the normal group [(1.21±0.25) vs (1.31±0.30) mmol/L, (1.107±0.154) vs (1.158±0.159) mmol/L] (all P<0.05). The increased systolic blood pressure, male, uric acid, U-mALB, NAG were independent correlative factors of Hcy elevation. Conclusion:The increase of Hcy is independently correlated with urine U-mALB and NAG, which suggests that the level of Hcy should be detected as soon as possible in patients with elevated early renal injury markers.

ABSTRACT

Objective@#To investigate the effects of ticagrelor on cardiorespiratory fitness in patients with coronary heart disease after percutaneous coronary intervention (PCI).@*Methods@#A total of 1 073 patients, who were diagnosed as coronary heart disease and underwent cardiopulmonary exercise testing (CPET) within 1 year after PCI, were enrolled from September 2017 to September 2019 in Peking University Third Hospital, including 309 patients in ticagrelor group and 764 patients in clopidogrel group. Clinical information, blood test results, echocardiographic parameters, cardiorespiratory fitness related parameters (including peak oxygen uptake (VO2), anaerobic threshold VO2, peak oxygen pulse (VO2/HR) and carbon dioxide ventilation equivalent (VE/VCO2) slope), coronary lesions and intervention information were obtained. Cardiopulmonary fitness related indexes were compared between the two groups, and the correlation between ticagrelor use and cardiopulmonary fitness related indexes was analyzed by multivariate logistic regression. Patients who underwent CPET within 1 month after PCI were included in the subgroup analysis.@*Results@#In ticagrelor group, the age was (60.3±10.3) years, and 253(81.9%) cases were male. The age of clopidogrel group was (60.6±10.0) years, and there were 608(79.6%) males. No significant differences were observed in peak VO2, anaerobic threshold VO2, and peak VO2/HR between the two groups (all P>0.05), but the VE/VCO2 slope was significantly higher in the ticagrelor group than in the clopidogrel group (30.075 (27.207, 33.603) vs. 28.853 (25.970, 32.336), P<0.001). Logistic regression analysis suggested that the peak VO2, anaerobic threshold VO2 and peak VO2/HR were not significantly correlated with the ticagrelor use (all P>0.05), while the VE/VCO2 slope was independently correlated with ticagrelor use (OR=1.098, 95%CI 1.032-1.168, P=0.003). Subgroup analysis of patients who underwent CPET within 1 month after PCI also indicated that no significant difference were observed in peak VO2, anaerobic threshold VO2, peak VO2/HR and VE/VCO2 slope between the two groups (all P>0.05). Logistic regression analysis suggested that the peak VO2, anaerobic threshold VO2 and peak VO2/HR were not significantly correlated with ticagrelor use (all P>0.05), while the VE/VCO2 slope was significantly correlated with ticagrelor use (OR=1.132, 95%CI 1.030-1.244, P=0.010).@*Conclusion@#Among coronary heart disease patients after PCI, treatment with clopidogrel does not result in significant decrease in exercise endurance as compared with patients treated with ticagrelor.

ABSTRACT

Objective@#To investigate the role of body fat ratio in the evaluation of obstructive sleep apnea(OSA).@*Methods@#A retrospective analysis was made on 174 cases (between November, 2017 and April, 2018 showed that) of sleep monitoring in the Department of Otorhinolaryngology in Peking University Third Hospital. The data included the gender, age, body fat rate, body mass index (BMI), neck circumference, and apnea-hypopnea index (AHI). The above data were analyzed by non parametric correlation analysis, receiver operating characterristic (ROC) curve analysis and multiple factor Logistic regression analysis to study the relationship between the gender,age,body fat rate,BMI,neck circumference and other indexes of the patients with AHI.@*Results@#Nonparametric correlation analysis showed that the correlation from strong to weak to AHI among women was BMI (r=0.621, P<0.001),body fat rate (r=0.602, P<0.001), age (r=0.570, P<0.001), neck circumference (r=0.402, P=0.014), respectively. BMI (r=0.599, P<0.001), neck circumference (r=0.493, P<0.001), body fat rate (r=0.318, P<0.001), and age (r=0.256, P=0.003) among men. ROC curve analysis showed that the strong to weak index (area under curve,AUC) of the AHI>15/h among women was the body fat rate (AUC=0.884, P=0.001), BMI(AUC=0.810, P=0.008), neck circumference (AUC=0.759, P=0.027), age (AUC=0.750, P=0.033), and the male was BMI (AUC=0.765,P<0.001), neck circumference (AUC=0.720, P<0.001), age (AUC=0.634, P=0.008), and body fat rate (AUC=0.632, P=0.010), respectively. Multifactor Logistic regression analysis showed that the body fat rate (OR=1.704,95%CI=1.012-2.870) in women was an independent risk factor for AHI greater than 15/h; the age of male (OR=1. 044, 95%CI=1.005-1.085) and BMI (OR=1.285, 95%CI=1.056-1.562) were independent risk factors for AHI greater than 15/h.@*Conclusion@#Body fat rate can be used as a new indicator for predicting the severity of OSA,especially in adult female population. In adult female moderate to severe OSA patients (AHI>15/h), compared with BMI,neck circumference and age,the body fat rate has the greatest correlation with AHI. Compared with BMI,neck circumference and age,the body fat rate has a decisive role in predicting moderate to severe OSA (AHI>15/h).

ABSTRACT

OBJECTIVE: To evaluate the effectiveness of oral contraceptive pill (OCP) as therapy for endometrial hyperplasia (EH) without atypia in reproductive-aged women compared with oral progestin. METHODS: A retrospective cohort study was carried out in our reproductive center. Consecutive patients diagnosed with infertility and non-atypical EH identified through electronic database who met inclusion criteria (n=309). Patients were assigned to two treatment groups: OCP (n=216) and oral progestin (n=93); clinical and reproductive outcomes were recorded. RESULTS: Reversal of EH to normal endometrium, clinical pregnancy, live birth and miscarriage rate. Women in OCP group were younger, had higher prevalence of Polycystic Ovary Syndrome and other uterine pathology and longer duration of infertility than women in progestin group. Reversal of EH was observed in 93.52% women on OCP and in 86.02% women on progestin (p=0.032; adjusted odds ratio [aOR]= 2.35; 95% confidence interval [CI]=1.06-5.21) after the initial course of treatment for 2 to 6 months. Cyclic OCP (n=184) resulted in better response to treatment compared to continuous OCP (n=32) (95.11% vs. 84.38%; p=0.039; aOR =3.60; 95% CI =1.12-11.55). Clinical pregnancy rate in OCP group was marginally higher than progestin group (87/208, 41.83% vs. 27/90, 30.00%; p=0.054). Miscarriage (25.29% vs. 29.63%; p=0.654) and live birth rate (31.25% vs. 21.11%; p=0.074) were comparable between the groups. CONCLUSION: For the first time we demonstrate that OCP is an effective therapy for non-atypical EH and is associated with higher remission rate compared with oral progestin. Reproductive outcomes are reassuring and comparable between the two groups.

ABSTRACT

Objective: To explore risk factors for cognitive impairment among elderly patients. Methods: There were 257 qualified subjects recruited, a case-control study was performed by collecting data of Mini Mental State Examination, carotid artery color Doppler flow imaging, biochemical tests, personal information on ages, medical histories, smoking as well as physical exercise among the recruited elderly in-patients/out-patients. A logistic regression was conducted to screen main effects of variables on occurrences of cognitive impairment. Results: Using logistic regression, the carotid intima-media thickness was found to be a significant risk factor (P<0.001) with larger regression coefficients (15.105 - 22.065) for the occurrence of cognitive impairment among elderly; about 71% -78% and 4% decrease in risks of dementia occurrence for every 1 pg/mL serum free triiodothyronine and lkg body weight increase. Conclusion: The increase in carotid intima-media thickness is a significant risk factor for the occurrence of cognitive impairment among elderly patients. The decrease in serum free triiodothyronine and body weight are the related factors to increase risk for dementia.

ABSTRACT

Background:Serum pepsinogens (PGs),as a serologic marker for gastric mucosal lesions,can reflect the functional status of gastric mucosa. Helicobacter pylori (Hp)infection can cause pathological changes in gastric mucosa,and has been reported to influence the serum level of PGs. Aims:To explore the influence of Hp infection on diagnostic performance of serum PGs for gastric mucosal lesions. Methods:The endoscopic findings,biopsy pathology (including Giemsa staining) and serum PGs test in 1216 cases of patients from July 2014 to June 2015 at the First Affiliated Hospital of Jiaxing University were collected. Patients were categorized according to the pathological diagnosis and Hp status,and the results of serum PGs test were analyzed between different groups. Results:When patients were classified by gastric mucosal lesion,no significant differences were found in serum levels of PGⅠ,PGⅡ,ratio for PGⅠ/ Ⅱ (PGR)and proportion of PG-positive (PGⅠ≤70 μg/ L and PGR < 3. 0)patients of different mucosal lesion groups with Hp-positive status (P >0. 05),whereas significant differences were observed in serum levels of PGⅠ,PGⅡ,PGR and proportions of patients with PGⅠ≤70 μg/ L or PGR < 3. 0 of different mucosal lesion groups with Hp-negative status (P < 0. 05). When patients were classified by Hp status,PGⅠ level and PGR were lower and PGⅡ level and proportion of PG-positive patients were higher in Hp-positive patients than in Hp-negative patients in any of the gastric mucosal lesion groups (P < 0. 05 in part of the comparisons). Conclusions:Hp infection is strongly associated with the alterations in serum PGs test,which narrows the differences in PGs between groups with different gastric mucosal lesions and expands that within the same mucosal lesion, subsequently decreasing PGR and increasing the proportion of PG-positive patients. Patients negative for Hp infection may need new cut-off value of serum PGs test to improve the sensitivity for diagnosis of gastric mucosal lesion.

ABSTRACT

Objective To evaluate the diagnostic significance of esophageal minimal change in gastroesophageal reflux disease (GERD) and explore its clinical characteristics.Methods From May to September in 2013,patients with minimal esophageal mucosa changes including esophageal mucosa rough,white secretin adhesion,erythema,edema,increased brittleness,blurring of the Z line or zigzag looking and blurring of paliform blood vessel,or patients with Los Angeles classification (LA) which were identified by endoscopy were enrolled.The subjects received gastroesophageal reflux disease questionnaire (GcrdQ) investigation and the related history were collected.The total score of GerdQ over eight was set as the criteria for GERD diagnosis.The R × C chi-square test was performed for statistical analysis.Results A total of 417 valid questionnaires were completed.Of which,202 cases were in minimal change group,176 were in LA A group and 36 were in LA-B group.The diagnostic rate of GERD in minimal change group was 20.3% (41/202),which was lower than that of LA-A group (74.4%,131/176) and LA-B group (83.3 %,30/36),and the differences were statistically significant (x2 =129.144,P<0.01).The incidences of heartburn in minimal change group,LA A group and LA-B group were 25.7% (52/202),62.5% (110/176) and 86.1% (31/36),respectively.The incidences of reflux were 29.7% (60/202),67.6% (119/176) and 75.0% (27/36),respectively.The incidences of non cardiac chest pain were 5.4% (11/202),22.2% (39/176) and 22.2%(8/36),respectively.The incidences of heartburn,reflux and non cardiac chcst pain of minimal change group were all lower than those of LA A group and LA-B group,and the differences were statistically significant (x2 =75.775,64.120,24.016;all P<0.01).The leading cause of endoscopy examination in minimal change group was abdominal discomfort,which accounted for 49.0%(99/202).The leading causes of endoscopy examination in LA A group and LA-B group were esophageal symptoms,which accounted for 52.8% (93/176) and 61.1% (22/36).Conclusions The diagnostic rate of GERD in patients of minimal change group is low and the clinical symptoms are not typical,which is insufficient for diagnosis of GERD and needed further investigation.

ABSTRACT

Objective To evaluate the efficacy of probiotics to treat irritable bowel syndrome (IBS).Methods Publications from database including PubMed,the Cochrane Library,Embase,CNKI,CBM and WanFang Data were searched up to August 31,2014.The randomized controlled trials (RCTs) on probiotics to treat IBS were eligible.The related articles were extracted and cross-checked independently by two reviewers.Methodological quality of trials was evaluated according to Cochrane Handbook 5.1.0 criteria.Meta-analysis was conducted using RevMan 5.2 software.Results A total of 17 RCTs involving 1 700 patients were included.Results of meta-analyses showed that compared with the placebo,probiotics was statistically better in improving the overall symptoms integral (SMD =-0.20,95% CI-0.33--0.07,P =0.002),alleviating abdominal pain/discomfort (SMD =-0.19,95% CI-0.29--0.09,P < 0.001),relieving abdominal distention (SMD =-0.16,95% CI-0.28--0.03,P =0.020),and defecation discomfort (SMD =-0.22,95% CI-0.42--0.02,P =0.030).There was no statistical significance in the overall quality of life (SMD =-0.08,95% CI-0.07-0.23,P =0.290) and adverse effect ratio (RR =1.08,95%CI0.79-1.49,P=0.630).Conclusion Probiotics have beneficial effects on IBS,which can improve the patients' symptoms and with less adverse reaction.Due to the bias,further large-scale,multicenter and high-quality RCTs are required to unify outcome indicators,further define sensitive strain,and standardize its usage,dosage and course of treatment.

ABSTRACT

Protein disulfide isomerase A3 (PDIA3) is a member of protein disulphide isomerase family and widely exists in endoplasmic reticulum, cell surface, nucleus and mitochondria.PDIA3 promotes the glycoprotein folding and quality control in the endoplasmic reticulum and is also a key molecular of major histocompatibility complex class I mol-ecules assembly.In addition, PDIA3 is involved in the cell signal transduction and plays an important role in a variety of disease development.Therefore, this paper talks about the function of PDIA3, the relationship between disease and PDIA3 as well as its clinical outlook.

ABSTRACT

<p><b>BACKGROUND</b>Pancreatic neuroendocrine tumors (pNETs) are a type of tumors with the characteristics of easy metastasis and recurrence. Till date, the risk factors affecting the prognosis are still in the debate. In this study, several risk factors will be discussed combined with our cases and experience.</p><p><b>METHODS</b>Thirty-three patients diagnosed as pNETs were enrolled and the clinical features, blood tests, pathological features, surgical treatment, and follow-up data of these patients were collected and analyzed.</p><p><b>RESULTS</b>In this study, operation time of G3 cases was longer than G1/G2 cases (P = 0.017). The elevated level of tumor markers such as AFP, CEA, Ca125, and Ca19-9 may predict easier metastasis, earlier recurrence, and poor prognosis (P = 0.007). The presence of cancer embolus and nerve invasion increases along with the TNM stage (P = 0.037 and P = 0.040), and the incidence of positive surgical margin increased (P = 0.007). When the presence of nerve invasion occurs, the chance of cancer embolus and lymph node metastasis also increases (P = 0.016 and P = 0.026).</p><p><b>CONCLUSIONS</b>pNETs were tumors with the features of easy recurrence and metastasis and many risk factors could affect its prognosis such as the elevated levels of tumor markers and the presence of nerve invasion, except some recognized risk factors. If one or more of these factors existed, postoperative treatments may be needed to improve prognosis.</p>

ABSTRACT

Objective To explore the risk factors of the occurence and 28-day death of acute respiratory distress syndrome (ARDS) in intensive care unit (ICU). Methods A prospective multicentral cohort study was conducted. The patients from five ICUs of grade A tertiary hospitals in Beijing from July 2009 to March 2014, including sepsis,septic shock,trauma,pneumonia,aspiration,massive blood transfusion,bacteremia and pulmonary contusion,were enrolled. Researchers in each center reported the records with uniform tables,which included demographic,systemic conditions,the primary disease,and the severity within 24 hours,past history and so on. According to the admission diagnosis in ICU,these patients were divided into ARDS group and other severe disease control group. The risk factors of occurence and prognosis of ARDS were analyzed by univariate analysis,multivariate logistic regression and multivariate COX regression analysis. Kaplan-Meier method was applied to draw the 28-day survival curves of the two groups. Results There were 343 critical patients included in this prospective multicenter cohort study,of which 163 patients who developed ARDS were considered as ARDS group(2 case lost to follow-up, and 49 died)and 180 patients who did not developed ARDS regarded as severe control group(1 case lost to follow-up, and 34 died). The 28-day mortality of ARDS group was significantly higher than that of severe control group〔30.43%(49/161)vs. 18.99%(34/179),χ2=6.013,P=0.014〕. Multivariate logistic analysis showed that aspiration〔odds ratio(OR)=6.390,95% confidence interval(95%CI)=2.046-19.953,P=0.001〕,history of alcohol (OR=4.854,95%CI=1.730-13.617,P=0.003),sepsis(OR=2.859,95%CI=1.507-5.425,P=0.001), pneumonia(OR=2.822,95%CI=1.640-4.855,P30 beats/min(OR=3.305,95%CI=1.910-5.721,P100 beats/min(OR=2.101,95%CI=1.048-4.213,P=0.037)happened in critically ill patients, it highly suggested ARDS would happen. The proportion of the patients whose serum creatinine>176.8 μmol/L in ARDS group was lower than that in control group(OR=0.387,95%CI=0.205-0.733,P=0.004). Multivariate COX regression analysis showed that old age and septic shock were significantly associated with the increased risk of in 28-day death of ARDS〔advanced age:hazard ratio(HR)=1.040,95%CI=1.018-1.064,P30 beats/min and heart rate>100 beats/min could predict the occurrence of ARDS in critical patients. Old age and septic shock were the risk factors of 28-day death of ARDS.
