Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Objective: To analyze the Staphylococcal enterotoxins, Staphylococcal enterotoxin genes, drug resistance and molecular typing of 41 Staphylococcus aureus isolates from 2 food-borne illness outbreaks on 21 August and 27 September 2020 in Guangzhou. Methods: A total of 41 Staphylococcus aureus isolates from 2 outbreaks were analyzed by multilocus sequence typing (MLST) and spa typing. The Staphylococcal enterotoxins typing and the Staphylococcal enterotoxin genes of the isolates were analyzed by ELISA and PCR, respectively. The antimicrobial susceptibility of the isolates was performed by disc diffusion. 21 Staphylococcus aureus isolates were characterized using whole genome sequencing (WGS). Based on the whole genome single nucleotide polymorphism (SNP), the phylogenetic tree was constructed by Snippy. Results: 41 Staphylococcus aureus isolates were divided into 2 types by MLST and spa typing: ST6-t701 and ST7-t091. 2 ST7-t091 isolates were identified as methicillin-resistant Staphylococcus aureus (MRSA). 25 ST7-t091 isolates and 14 ST6-t701 isolates were methicillin-sensitive Staphylococcus aureus (MSSA), and were resistant to 7 and 6 antibiotics, respectively. All isolates were positive for sea by PCR. WGS revealed all 21 isolates carried scn, sak, sea, hla, hld, hlgA, hlgB, hlgC, lukD virulence genes. The results showed the isolates contained an immune evasion cluster type D which located in bacteriophage ϕSa3. The SNP phylogenetic tree showed 2 MRSA ST7-t091 were constituted a separate clade from the 12 MSSA ST7-t091 isolates and 7 ST6-t701 isolates showed high similarity to each other. Conclusion: Base on the results of phylogenetic analysis, the 2 food-borne illness outbreaks occurred on 21 August and 27 September 2020 are caused by the combination of the MRSA ST7-t091 strain and the MSSA ST7-t091 strain, and the MSSA ST6-t701 strain, respectively. All isolates have high level of antibiotic resistance and carry high virulent genes.

This study aims to compare the prevalence of sexually transmitted infections (STIs) with semen quality in men from couples with primary and secondary infertility. Semen samples were collected from 133 men who requested fertility evaluation. Seminal tract infection with Ureaplasma spp. (UU), Mycoplasma hominis (MH), Mycoplasma genitalium (MG), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and herpes simplex virus-2 (HSV-2) was assessed by PCR-based diagnostic assays. Among all patients, the prevalence of STIs was higher in men from couples with primary infertility than that in men from couples with secondary infertility (39.7% vs 21.7%, P = 0.03). The prevalence of UU was 28.8% and 13.3% in men from couples with primary and secondary infertility, respectively. Men from couples with primary infertility were more likely to be positive for UU than men from couples with secondary infertility (P = 0.04). Regarding the UU subtype, the prevalence of Ureaplasma urealyticum (Uuu) and Ureaplasma parvum (Uup; including Uup1, Uup3, Uup6, and Uup14) did not differ between the two groups. No associations between the prevalence rates of MH, MG, and CT were found in men from either infertility group. A lower sperm concentration was associated with STI pathogen positivity in men with primary infertility according to the crude model (P = 0.04). The crude and adjusted models showed that semen volume (both P = 0.03) and semen leukocyte count (both P = 0.02) were independently associated with secondary infertility. These findings suggest the importance of classifying the type of infertility during routine diagnosis of seminal tract infections.

Background: A patient’s infectivity is determined by the presence of the virus in different body fluids, secretions, and excreta. The persistence and clearance of viral RNA from different specimens of patients with 2019 novel coronavirus disease (COVID-19) remain unclear. This study analyzed the clearance time and factors influencing 2019 novel coronavirus (2019-nCoV) RNA in different samples from patients with COVID-19, providing further evidence to improve the management of patients during convalescence. Methods: The clinical data and laboratory test results of convalescent patients with COVID-19 who were admitted to from January 20, 2020 to February 10, 2020 were collected retrospectively. The reverse transcription polymerase chain reaction (RT-PCR) results for patients’ oropharyngeal swab, stool, urine, and serum samples were collected and analyzed. Convalescent patients refer to recovered non-febrile patients without respiratory symptoms who had two successive (minimum 24 h sampling interval) negative RT-PCR results for viral RNA from oropharyngeal swabs. The effects of cluster of differentiation 4 (CD4)+ T lymphocytes, inflammatory indicators, and glucocorticoid treatment on viral nucleic acid clearance were analyzed. Results: In the 292 confirmed cases, 66 patients recovered after treatment and were included in our study. In total, 28 (42.4%) women and 38 men (57.6%) with a median age of 44.0 (34.0–62.0) years were analyzed. After in-hospital treatment, patients’ inflammatory indicators decreased with improved clinical condition. The median time from the onset of symptoms to first negative RT-PCR results for oropharyngeal swabs in convalescent patients was 9.5 (6.0–11.0) days. By February 10, 2020, 11 convalescent patients (16.7%) still tested positive for viral RNA from stool specimens and the other 55 patients’ stool specimens were negative for 2019-nCoV following a median duration of 11.0 (9.0–16.0) days after symptom onset. Among these 55 patients, 43 had a longer duration until stool specimens were negative for viral RNA than for throat swabs, with a median delay of 2.0 (1.0–4.0) days. Results for only four (6.9%) urine samples were positive for viral nucleic acid out of 58 cases; viral RNA was still present in three patients’ urine specimens after throat swabs were negative. Using a multiple linear regression model (F=2.669, P=0.044, and adjusted R²=0.122), the analysis showed that the CD4+ T lymphocyte count may help predict the duration of viral RNA detection in patients’ stools (t=-2.699, P=0.010). The duration of viral RNA detection from oropharyngeal swabs and fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (15 days vs 8.0 days, respectively; t=2.550, P=0.013) and the duration of viral RNA detection in fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (20 days vs 11 days, respectively; t=4.631, P <0.001). There was no statistically significant difference in inflammatory indicators between patients with positive fecal viral RNA test results and those with negative results (P >0.05). Conclusions In brief, as the clearance of viral RNA in patients’ stools was delayed compared to that in oropharyngeal swabs, it is important to identify viral RNA in feces during convalescence. Because of the delayed clearance of viral RNA in the glucocorticoid treatment group, glucocorticoids are not recommended in the treatment of COVID-19, especially for mild disease. The duration of RNA detection may relate to host cell immunity.

Objective:To explore the association between the spontaneous neural activity and memory function in depressive patients with different sleep quality.Methods:Totally 58 patients with depressive disorder and 58 gender-, age-, education-matched healthy controls (HC) completed 3.0 T MRI Scanning and clinical assessment including Wechsler memory scale (WMS), 24 Hamilton depression scale(HAMD-24) and Pittsburgh sleep quality index (PSQI). According to the score of PSQI, patients were divided into poor sleep quality group (PS, n=38) and good sleep quality group (GS, n=20). Amplitude of low frequency fluctuations (ALFF) were calculated and compared among three groups.Correlation analyses between the brain activity and the score of WMS were conducted as well. Results:Memory quotient of WMS showed differences among three groups( F=14.163, P<0.01), and the lowest score was found in patients with low sleep quality.The brain areas showed significant differences among three groups located in the left medial superior frontal gyrus (lmSFG, MNI: x=-10, y=30, z=58; K=56), right orbital inferior frontal gyrus (roIFG, MNI: x=26, y=20, z=-26; K=24) and left middle frontal gyrus (lMFG, MNI: x=-40 y=32, z=42; K=25) (voxel size P<0.001, cluster size P<0.05, GRF corrected). Compared with GS group, the ALFF of PS group showed significantly increased in the lmSFG, which was negatively correlated with memory quotient ( r=-0.327, P=0.045) and short term memory( r=-0.388, P=0.016). Compared with HC group, the ALFF of PS group showed increased in the lmSFG and lMFG, GS group showed increased ALFF in the roIFG. Conclusion:The impairment of memory function is more serious in patients with depression of low sleep quality, and the activity of frontal lobe is abnormally increased, which is related to memory function.Their association suggests that poor sleep quality in depressive patients may impair memory function by disrupting neural plasticity and synaptic pruning in the frontal lobes.

Objectives: Modified extended Morrow procedure for treatment of children with hypertrophic obstructive cardiomyopathy (HOCM) is a complicated and challenging procedure. Our study sought to assess the effect and outcome of modified extended Morrow procedure in children with HOCM. Methods: From January 2010 to July 2017, 50 consecutive pediatric (age≤14 years) patients with HOCM underwent transaortic modified extended Morrow procedure in Fuwai Hospital. Clinical data of these patients were analyzed retrospectively. Pre-operative and post-operative echocardiography data were analyzed, including left atrial size, left ventricular end diastolic diameter, left ventricular ejection fraction, left ventricular outflow tract peak pressure, ventricular septal thickness, mitral systolic anterior motion and grade of mitral regurgitation. Results: Mean age at the time of operation was (84.4±57.7) month (6 month -14 year). Mean body weight at the time of surgery was (28.4±20.7) kg (4.3-92.0) kg. There were 2 deaths after the operation. Three patients had postoperative complete heart block and received permanent pacemaker implantation. After myectomy, left ventricular outflow tract gradient decreased from (74.8±25.0) mmHg to (19.6±17.3) mmHg (P<0.001); the postoperative thickness of ventricular septum decreased from (21.2±9.7) mm to (14.3±6.7) mm (P<0.001); mitral regurgitation degree reduced from 2.2±1.0 to 0.67±0.72, P<0.001). Concomitant surgical procedures were required in 22 patients (44.0%). There was no late death during a follow-up of (27.7±14.0) months. Patients' symptoms were significantly improved post operation and all surviving patients were in New York Heart Association functional class I or II during follow-up. Conclusions: Modified extended Morrow procedure is safe and effective in children with HOCM, post-procedural clinical outcome is excellent, and this procedure can significantly improve the quality of 1ife and the long-term prognosis in these patients.

Objective To explore the role of functional connectivity( FC) between the subgenual anterior cingulate cortes(sgACC) and limbic cortices in predicting the efficacy of early antidepressant treat-ment. Methods Resting state magnetoencephalography( MEG) data were collected from 32 patients with major depressive disorder(MDD) and 20 matched healthy control subjects at baseline.According to whether the HAMD17total score reduction rate reached 50% after 2 weeks,the patients were divided into responder group and non-responder group.The difference of the FC,the relationship between the FC and the change rate of HAMD17were explored. Results Compared with controls,MDD patients showed decreased connectivity of the sgACC with the right hippocampus(MNI coordinate:x＝30,y＝－3,z＝－24; F＝5.11,P＝0.028),the right amygdala(MNI coordinate:x＝22,y＝－2,z＝－15; F＝6.90,P＝0.012) and the left amygdala(MNI coordi- nate:x＝－24,y＝－6,z＝－16; F＝5.75,P＝0.020).Compared with non-responders,the connectivity of the sgACC with the right hippocampus(MNI coordinate:x＝30,y＝－3,z＝－24;F＝8.74,P＝0.0065),the right a-mygdala(MNI coordinate:x＝22,y＝－2,z＝－15; F＝12.417,P＝0.0016) were higher in responders.Pretreat-ment connectivity of the sgACC with the right hippocampus(r＝－0.50,P＝0.0066),the right amygdala(r＝－0.56,P＝0.0018) were negatively correlated with clinical improvement.ROC analyses confirmed the value of the connectivity of sgACC with the right hippocampus(area under curve(AUC)＝0.71,P＝0.042),the right amygdala(AUC＝0.73,P＝0.029) in classifying responders versus non-responders in 2 weeks of treatment. Conclusion The decreased FC of the sgACC with the right hippocampus and the right amygdala at baseline is associated with a better improvement,which can potentially serve as a treatment outcome biomarker in ear-ly curative effect of depression.

Objective To research the role of phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in the pathogenesis of alcoholic liver injury in mice.Methods Healthy and mature male mice were reared normally.They were divided at random into 5 groups,namely the normal group (n =10),the experimental-1 group (n =10),the experimental-2 group (n =10),the experimental-3 group(n =10),the experimental-4 group(n =10).The normal group was not treated.The mouse in experimental-1 group,experimental-2 group,experimental-3 group,experimental-4 group were given uninterruptedly 56 degree Beijing Red Star Erguotou by intragastric administration(14 mL · kg-1) for preparation of alcohol liver injury in mice.At the first week,the second week,the third week and the fourth week,respectively,the blood of mice was taken directly by eyeball enucleation.The serum levels of aspartate aminotransferase(AST) was measured with a aspartate aminotransferase assay kit.The expression levels of p-STAT3 in liver of mice was measured by Western blot.Results The serum levels of AST in normal group,experimental-1 group,experimental-2 group,experimental-3 group,experimental-4 group were (112 ±22),(126 ±24),(967 ±30),(1010 ±35),(206 ±23) U · L-1;comparison between experimental-1 group,experimental-4 group and normal group,the difference were without significantly (all P ＞ 0.05);comparison between experimemal-2 group,experimental-3 group and normal group,the difference had significantly (all P ＜ 0.01).The expression levels of p-STAT3 in the 5 groups were (0.52 ± 0.11),(3.21 ±0.33),(1.12 ± 0.21),(1.51 ± 0.23),(2.13 ± 0.26) AU;comparison between experimental-1 group,experimental-4 group and normal group,the difference had significantly (all P ＜ 0.01);comparison between experi mental-2 group,experimental-3 group and normal group,the difference had significantly(all P ＜0.05).ConclusionP-STAT3 may be involved in the acute phase response in the early stage of liver injury in mice,and participate in and promote hepatocyte injury.In the later stage,it may be beneficial to the regeneration,repair and inhibition of hepatocyte apoptosis.

Objective: To investigate the clinical effect of a novel disposable ring versus that of the suture device in circumcision for redundant prepuce and phimosis. METHODS: We randomly assigned 470 male patients with redundant prepuce or phimosis to receive circumcision with a novel disposable ring (the DR group, n = 235) or the suture device (the SD group, n = 235) and compared the operation time, intraoperative blood loss, pain scores, wound healing time, and postoperative complications and penile appearance between the two groups of patients. RESULTS: All the operations were completed smoothly. Compared with the SD group, the DR group showed significantly shorter operation time (［7.49 ± 1.84］ vs ［3.83 ± 0.42］ min, P <0. 05), less intraoperative blood loss (［3.34 ± 2.59］ vs ［2.41 ± 1.01］ ml, P <0.05), lower intraoperative pain score (0.57 ± 0.76 vs 0.20 ± 0.47, P <0.05) and 6-hour postoperative pain score (3.42 ± 1.12 vs 0.48 ± 0.94, P <0.05), shorter wound healing time (［12.05 ± 2.80］ vs ［7.79 ± 1.65］ d, P <0.05), lower incidence rates of postoperative glans congestion or edema (36.17% ［85/235］ vs 2.56% ［6/235］, P <0.05), dysuria or strenuous urination (34.04% ［80/235］ vs 2.13% ［5/235］, P <0.05) and bleeding or hematoma (5.11% ［12/235］ vs 1.28% ［3/235］, P <0.05), and higher satisfaction with postoperative penile appearance (90.6% ［213/235］ vs 95.8% ［228/235］, P <0.05). There were no statistically significant differences between the SD and DR groups in the pain scores at the sixth night after operation (1.31 ± 0.96 vs 1.34 ± 1.07, P >0.05) or while the staples scraping the underpants or at the ring removal (3.49 ± 1.22 vs 3.36 ± 1.41, P >0.05). No obvious postoperative infection or delayed healing was observed except for 3 cases of wound dehiscence (1 in the DR and 2 in the SD group) and 8 cases of delayed removal of the staples in the SD group. CONCLUSIONS The novel disposable ring, with its advantages of short operation time, less bleeding and pain, good penile appearance, high safety, and simple operation, is obviously superior to the suture device in circumcision and deserves to be applied and popularized clinically. .
