Objective To investigate the seroprevalence of Toxoplasma gondii infections among patients with diabetes mellitus in Hangzhou City. Methods A total of 337 patients with type 1 diabetes mellitus, 624 patients with type 2 diabetes mellitus and 384 patients with gestational diabetes mellitus living in Hangzhou City during the period from March 2017 through May 2020 were recruited as the study subjects, while age- and gender-matched healthy volunteers and pregnant women without gestational diabetes mellitus served as controls. Enzyme-linked immunosorbent assay (ELISA) was employed to detect serum IgG and IgM antibodies against T. gondii in patients with diabetes mellitus and controls, and the seroprevalence of anti-T. gondii antibody was compared between diabetes mellitus patients and controls. Results The overall seroprevalence of anti-T. gondii antibody (18.10% vs. 4.45%, χ² = 31.38, P < 0.01) and the seroprevalence of anti-T. gondii IgG antibody (14.54% vs. 2.97%, χ² = 28.28, P < 0.01) were both significantly higher in patients with type 1 diabetes mellitus than in healthy controls, while no significant difference was seen in the seroprevalence of anti-T. gondii IgM antibody between patients and controls (3.56% vs. 1.48%, χ² = 2.96, P > 0.05). The seroprevalence rates of serum anti-T. gondii (23.56% vs. 6.57%, χ² = 70.37, P < 0.01) and anti-T. gondii IgG antibodies (21.15% vs. 5.45%, χ² = 66.73, P < 0.01) were significantly higher in patients with type 2 diabetes mellitus than in healthy controls, while no significant difference was seen in the seroprevalence of anti-T. gondii IgM antibody between patients and controls (2.40% vs. 1.12%, χ² = 2.96, P > 0.05). In addition, the overall seroprevalence of serum anti-T. gondii antibody (26.30% vs. 19.53%, χ² = 4.98, P < 0.05) and the seroprevalence of anti-T. gondii IgG antibody (23.70% vs. 17.71%, χ² = 4.20, P < 0.05) were both significantly higher in patients with gestational diabetes mellitus than in pregnant women without gestational diabetes mellitus, while no significant difference was seen in the seroprevalence of anti-T. gondii IgM antibody between pregnant women with and without gestational diabetes mellitus (2.60% vs. 1.82%, χ² = 0.54, P > 0.05). Conclusions The patients with diabetes mellitus present a higher seroprevalence rate of anti-T. gondii antibody than controls in Hangzhou City. Screening of T. gondii infections and health education pertaining to toxoplasmosis prevention and control knowledge should be reinforced in patients with diabetes mellitus.

Objective:To retrospectively analyze the clinical and serological characteristics in rehabilitated patients with common novel coronavirus pneumonia(COVID-19).Methods:A total of 165 patients with common COVID-19 were enrolled in this retrospective study, in which clinical data was collected from February 23 to March 15, 2020 in Leishenshan Hospital(Wuhan, China). The patients with COVID-19 were divided into elderly group and non-elderly group according to their age, and the differences in the clinical and serological metabolic characteristics between these two groups were analyzed.Results:49.7% patients were over 60 years old. The most common clinical symptoms were fever, cough, and fatigue, followed by muscle soreness. Expectoration and digestive tract symptoms were rare. Dyspnea occurred more frequently in the elderly group than in non-elderly group(47.56% vs 25.30%, P<0.01). Hypertension was the most common concomitant disease(accounting for 29.1%)followed by diabetes. Hypertension was more common in the elderly group than in non-elderly group(41.46% vs 16.86%, P<0.01), but without significant difference in diabetes between the two groups. The counts of leukocytes and lymphocytes in all patients were in the normal range, and no difference was observed between the groups. The comparison of serological indicators showed that serum creatinine in the elderly group was higher than that in the non-elderly group( P<0.01)while serum albumin, glomerular filtration rate, and serum calcium were lower in the elderly group. After serum albumin correction, the levels of albumin corrected calcium in all patients were in the normal range, without significant difference between these two groups. There was no significant difference between the two groups when the length of hospital stay was taken as the index of outcome [(34.01±10.24) vs(30.97±10.51)d, P>0.05]. Conclusion:Fever, cough, and fatigue are the most common clinical symptoms in patients with ordinary COVID-19. The elderly are more likely to develop dyspnea. The blood routine and metabolic characteristics in patients with common COVID-19 are normal, but serum albumin level is more likely to decrease in elderly patients with COVID-19.

Objective To evaluate the effectiveness of urgent surgical correction for infra-cardiac total anomalous pulmonary venous connection(TAPVC)in neonates.Methods From October 2009 to Janu-ary 2015,13 patients with infra-cardiac TAPVC received surgical correction.The age of patients ranged from 6 to 28 days[(15.08 ±7.42)days],the body weight ranged from 2.5 to 4.8 kg [(3.34 ±0.67)kg].A median sternotomy was performed.Continuous cardiopulmonary bypass using bicaval cannulation with aortic cross-clamping and mild systemic hypothermia were used in all patients.Bi-atrial incision technique making anastomosis between the posterior left atrial wall and the vertical vein were employed in 3 cases.In the other 10 cases,the heart was elevated upward and to the right to expose the anomalous descending vertical vein to facilitate the anastomosis between the posterolateral left atrial wall and vertical vein.Results Emergent or subemergent operations were performed in all patients without surgical death.In the early stage after opera-tion,delayed sternal closure was employed in 1 1 patients,pulmonary hypertension crisis occurred in 3 pa-tients,small atrial septal defect was kept open for hemodynamic stabilization in 6 patients,temporary cardiac pacemaker for proper heart rate in 3 patients.All patients were uneventfully discharged except 2 patients died of severe low cardiac output syndrome.During the period of follow up,2 patients presented with recurrent pulmonary infection and signs of pulmonary venous obstruction including the increased flow speed at the site of anastomosis.One of 2 patients was lost of follow up and the other patient was uneventfully discharged after the second operation.The rest 9 patients received postoperative follow up for 1 month to 5 years,echocardio-graphy,X ray chest radiography,and electrocardiogram were performed during this period.As a result,all children had good cardiac function and with sinus rhythm on electrocardiogram and apparently reduced pul-monary congestion on radiography.No obstructive pulmonary venous return was observed on echocardio-graphy.Conclusion Corrective operation for infra-cardiac TAPVC in neonate on urgent basis may provide favorite outcomes.

Objective: Recurrence is the most significant feature of depression and the relationship between iron and recurrent depression is still lack of direct evidence in vivo. Methods: Twenty-one patients with depression and twenty control subjects were included. Gradient-recalled echo, T1 and T2 images were acquired using a 3.0T MRI system. After quantitative susceptibility mapping were reconstructed and standardized, a whole-brain and the regions of interest were respectively analyzed. Results: Significant increases in susceptibility were found in multiple recurrent depression patients, which involved several brain regions (frontal lobes, temporal lobe structures, occipital lobes hippocampal regions, putamen, thalamus, cingulum, and cerebellum). Interestingly, no susceptibility changes after treatment compared to pre-treatment (all p>0.05) and no significant correlation between susceptibility and Hamilton Depression Rating Scale were found. Besides, it was close to significance that those with a higher relapse frequency or a longer mean duration of single episode had a higher susceptibility in the putamen, thalamus, and hippocampus. Further studies showed susceptibility across the putamen (ρ2=0.27, p<0.001), thalamus (ρ2=0.21, p<0.001), and hippocampus (ρ2=0.19, p<0.001) were strongly correlated with total course of disease onset. Conclusion Brain iron deposition is related to the total course of disease onset, but not the severity of depression, which suggest that brain iron deposition may be a sign of brain damage in multiple recurrent depression.

Objective To investigate the prevalence of tuberculosis among silicosis patients and silica exposure patients,and to analysis the risk factors of tuberculosis among these population.Methods A total of 1 227 silica exposure patients from Wenling,Zhejiang were enrolled in this field study.Basic demographic information was collected and chest X-ray was taken for each patient.Sputum was collected for Mycobacterium tuberculosis culture and strain identification. In univariate analysis,t test was performed for continuous variables andχ2 test for categorical variables.In multivariate analysis,the odds ratio (OR )was calculated along with a 95 % confidence interval (CI )by binary Logistic regression. Results A total of 1 204 silica exposure patients had full basic information and 99.8% were male patients with mean age of (59.4 ± 6.8 )years.The patients in phase 0 + to phase Ⅲ were 172 (14.3%),255 (21 .2%),160 (13.3%)and 617 (51 .2%),respectively.The tuberculosis prevalence rate was about 7.3% among these population.The risk factors for tuberculosis including phase Ⅱ silicosis (OR =2.96, 95 %CI :1 .05 -8.32,P =0.04)and phase Ⅲ silicosis (OR=3.88,95 %CI :1 .58-9.56,P <0.01),and contacting with tuberculosis patients (OR=4.14,95 %CI :1 .91 -8.98,P <0.01).Patients complicated with tuberculosis lacked specific symptoms,but fever and weight loss were more frequent.Conclusion Tuberculosis is highly prevalent in silicotic patients,especially in patients with phase Ⅱ/Ⅲ silicosis and in patients with tuberculosis contact history.

Objective: To investigate the clinical significance of transcranial Doppler (TCD) in early diagnosis of sepsis-associated encephalopathy(SAE). Methods: Septic patients admitted to the intensive care unit(ICU) were recruited at Xiangya Hospital, Central South University from July 2015 to March 2016. Clinical data and TCD parameters during 24 hours after admission were collected. All patients were screened for delirium using the confusion assessment method for the intensive care unit (CAM-ICU) twice a day. The gold standard of the diagnosis of SAE was positive CAM-ICU evaluation. Patients were divided into SAE group and the non-SAE group. TCD data including systolic velocity (Vs), diastolic velocity (Vd), mean velocity (Vm), pulsatility index (PI) and resistant index (RI) were analyzed to determine the optimal diagnostic cut-off value. Results: A total of 43 patients were enrolled including 12 in SAE group and 31 in non-SAE group. Vm and Vd were lower in SAE group [Vm: (53.50±12.22) cm/s vs. (61.68±9.63) cm/s, P<0.05; Vd: (33.42±10.87) cm/s vs. (43.16±7.84) cm/s, P<0.01] but PI and RI were significant higher in SAE group[PI:(1.16±0.2) vs. (0.90±0.15), P<0.01;RI:(0.65±0.08) vs. (0.56±0.06), P<0.01] than in non-SAE group. The cut-off values of Vs, Vm, Vd, PI and RI for the diagnosis of SAE were 112cm/s, 55.50cm/s, 34.50cm/s, 1.16, 0.65, respectively, with the relevant sensitivities of 19.4%, 83.9%, 93.5%, 58.3%, 58.3% and the specificities of 100.0%, 50.0%, 58.3%, 96.8%, 96.8%, respectively. The diagnostic AUC of Vd, PI and RI were 0.741, 0.808 and 0.808 respectively. Conclusions The parameter changes of TCD suggest that the pathogenesis of SAE is related to cerebral hypoperfusion, TCD is a helpful method for the early diagnosis of SAE.

Objective:To explore the psychometric characteristics of the Chinese version of the health-related social capital scale.Methods:From March to May 2020, after the original scale was translated into Chinese following the Brislin improved translation model, 251 community-dwelling senior citizens aged 65 and above were selected by convenient sampling method. Data analysis was conducted using SPSS 22.0 and AMOS 22.0, including tests of significance, correlation analysis, exploratory factor analysis, and confirmatory factor analysis.Results:Exploratory factor analysis extracted three factors: social participation, social cohesion, and reciprocity, which accounted for a cumulative contribution rate of 61.72%. Confirmatory factor analysis showed that the three-factor model fitted well(χ 2/ df=1.22, RMSEA=0.04, CFI=0.98, GFI=0.93, IFI=0.98, TLI=0.97). Social capital was significantly correlated with perceived social support positively ( r=0.36, P<0.01), and with loneliness negatively ( r=-0.30, P<0.01). The three factors were significantly correlated with the total scale ( r=0.85, 0.50 and 0.52, respectively, all P<0.01). And correlations between the items of each factor were 0.24-0.55, 0.30-0.59, 0.44-0.70, respectively(all P<0.01). The Cronbach's α coefficients of the total scale and three factors were 0.74, 0.72, 0.65 and 0.62, respectively(all P<0.01), and their retest reliability were 0. 92, 0. 87, 0. 82 and 0. 96, respectively(all P<0.01). Conclusion:The Chinese version of health-related social capital scale conforms to the three-factor model with good reliability and validity, which can be used to assess the social capital status of community-dwelling older adults in China.

OBJECTIVETo compare the positive rates and complications of ultrasound-guided transrectal and transperineal prostate biopsies.

METHODSWe retrospectively analyzed 156 cases of ultrasound-guided transrectal (n = 97) and transperineal (n = 59) prostate biopsy, and compared the positive rate and post-biopsy complications between the two approaches.

RESULTSThe positive rates in the transrectal and transperineal groups were 48.4% and 44.1%, respectively, with no significant difference between the two approaches according to different PSA levels (P >0.05). No statistically significant differences were observed between the transrectal and transperineal groups in the post-biopsy incidence rates of such complications as hematuria (54.6% vs 42.4%, P >0.05), lower urinary tract symptoms (17.5% vs 22.0%, P >0.05), dysuria (9.3% vs 6.8%, P >0.05), and acute urinary retention (7.2% vs 6.8%, P >0.05). However, the incidence rates of post-biopsy infection and rectal bleeding were remarkably higher (15.5% vs 3.4%, P<0.05 and 50.5% vs 3.4%, P >0.01) while that of perineal swelling markedly lower in the former than in the latter (3.1% vs 13.6%, P <0.05).

CONCLUSIONTransrectal and transperineal biopsies are both effective for the diagnosis of prostate cancer. Since their complications vary, the choice between the two methods depends on the specific condition of the patient.

Objective:To investigate the relationship between n7-methylguanosine (m7G) related long non-coding RNA (lncRNA) expression and glioma prognosis, and to construct a prognosis model with m7G-related lncRNA in patients with glioma.Methods:Data related to the test set and validation set were downloaded from the Cancer and Tumor Genome Atlas (TCGA) database and the China Glioma Genome Atlas (CGGA) database. LASSO regression and random forest algorithm were used to establish the glioma prognosis model with m7G related lncRNA. Individualized risk scores were calculated using the weighted expression levels of the 12 extracted lncRNA coefficients, and test set and validation set glioma patients were categorized into high and low risk groups based on median risk score. Kaplan-Meier survival curve was drawn, the comparison method used log rank test. The efficacy of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was evaluated using the receiver operating characteristics (ROC) curve.Results:A total of 12 lncRNA associated with m7G were obtained, with a risk score = 1.026 × AC002454.1 + 1.086 × AC131097.4 + 1.039 × AC147651.3 + 1.01 × AGAP2-AS1 + 1.036 × CRNDE + 0.733 × GDNF-AS1 + 1.321 × HOXD-AS2 + 0.934 × LINC00641 + 1.183 × PAXIP1-AS2 + 1.258 × PVT1 + 0.909 × SOX21-AS1 + 0.754 × TTC28-AS1, with a median risk score of - 0.45 scores. Kaplan-Meier survival curve analysis result showed that the median survival time in high risk group was significantly shorter than that in low risk group (1.98 years vs. 9.51 years, log-rank χ2 = 131.78, P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was 0.891, 0.923 and 0.912. In the validation set of glioma patients, Kaplan-Meier survival curve analysis result showed that the median survival time in high risk group was significantly shorter than that in low risk group (1.29 years vs. 6.88 years, log-rank χ2 = 103.27, P<0.01); ROC curve analysis result showed that the AUC of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was 0.724, 0.795 and 0.762. In the test set and validation set, multivariate Cox regression analysis result showed that the risk score was the independent risk factors of prognosis in patients with glioma ( HR = 1.992 and 1.247, P<0.01 or <0.05). Conclusions:A risk score model with m7G related lncRNA based on transcriptome is a novel approach to predict the prognosis of glioma patients.

Objective To investigate the diagnostic value of neuron-specific enolase(NSE),central nervous system specific protein (S100β),interleukin-6 (IL-6) in sepsis-associated encephalopathy (SAE).Methods Clinical data of patients admitted to ICU and diagnosed with sepsis were collected from January 2015 to June 2016 in Xiangya Hospital,Central South University.SAE was defined as cerebral dysfunction in the presence of sepsis that also fulfilled the exclusion criteria.The acute physiology and chronic health score (APACHE Ⅱ),sequential organ failure assessment (SOFA),NSE,S100β,IL-6,ICU stay time and 28-day mortality were compared between the two groups.NSE,S1003 and IL-6 were measured on the 1 st and 3rd day in ICU to determine the optimal cut-off value of SAE.Results Among 59 enrolled patients,36 were assigned to SAE group while 23 were non-SAE group.The SAE group had a significantly higher APACHE Ⅱ and SOFA scores,as well as the length of ICU stay (P ＜ 0.01).The levels of NSE,S1003 and IL-6 in the two groups both increased on the 1st day,and decreased on the 3rd day.The level of NSE on the 1st day [19.28 (13.00,30.52) μg/L vs 16.61 (7.58,22.01 μg/L)] and the 3rd day[16.03 (9.40,21.29) μg/L vs 11.39(8.49,15.00) μg/L,P=0.029],IL-6 on the 1st day[676.25(81.34,5 000.00) mg/L vs [209.10(42.27,648.20) mg/L,P =0.005] and the 3rd day [157.10 (72.85,687.63) mg/L vs 55.92 (31.62,177.00) mg/L,P =0.026] of SAE group was significantly higher than those of non-SAE group.However S100β between groups on the 1st day [0.33(0.15,0.54) μg/L vs 0.23(0.16,0.53) μg/L] and the 3rd day[0.19(0.10,0.29) μg/L vs 0.10(0.05,0.17) μg/L] was neither significant (P ＞0.05).The diagnostic values for SAE of NSE,S1003 and IL-6 were 14.36 μg/L,0.14 μg/L and 91.305 mg/L with sensitivity 61.1％,61.1％,72.2％ and specificity 73.9％,69.6％,69.6％,respectively.The diagnostic AUC of NSE and IL-6 combination was 0.774,95％ CI 0.651-0.896.Conclusion All sepsis patients have different degrees of brain injury.NSE combined with IL-6 on the 3rd day in ICU demonstrates the diagnostic significance of SAE.
