Objective: To explore the relationship between thyroid hormone levels and prolonged recovery after cardiac surgery with cardiopulmonary bypass (CPB) in congenital heart disease (CHD) children younger than 1 year of age. Methods: A total of 186 CHD children younger than 1 year treated in our hospital from 2014-01 to 2015-01 were retrospectively summarized. According to the pediatric intensive care unit (PICU) stay time, the patients were divided into 2 groups: Prolonged recovery group, the patients stated in PICU≥5 days,n=39 and Non-prolonged recovery group, the patients stayed in PICU<5 days,n=147. Thyroid hormone levels within 24 hours of operation with prolonged recovery conditions were studied. Results: Compared with Non-prolonged recovery group, the patients in Prolonged recovery group showed decreased levels of FT3 (2.02 ± 0.48) pg/ml vs (2.27 ± 0.46) pg/ml, TT3 (0.59 ± 0.30) ng/dl vs (0.71 ± 0.24) ng/dl and TT4 (5.39 ± 2.58)μg/ml vs (6.49 ± 2.20) μg/ml, allP<0.05; while the levels of free thyroid hormone and thyrotropin were similar between 2 groups,P>0.05. Multivariable logistical regression analysis presented that low level of FT3 within 24 hours of operation was the independent risk factor for prolonged recovery (OR= 0.32, 95% CI 0.12-0.84,P=0.02); linear regression analysis indicated that post-operative reduction of thyroid hormone was related to low body weight of the patients (r=0.11,P<0.001). Conclusion: Lower body weight was usually having lower level of FT3 within 24 hours of operation, which was the independent predictor for prolonged recovery in CHD children younger than 1 year after cardiac surgery.

Objective To explore the quality of life ( QoL ) and muscle strength in patients with pseudohypoparathyroidism ( PHP ) under regular treatment. Methods Twenty-three patients with PHP regularly followed at Peking Union Medical College Hospital from June 2017 to June 2018 were included. Age- and gender-matched 23 patients with nonsurgical hypoparathyroidism ( nHPT) and 23 healthy controls were also included. Short Form 36 Health Survey questionnaire version 2 ( SF36v2) were used to evaluate the QoL. Grip strength and repeated chair stand ( RCS) were used to assess muscle strength for upper and lower limbs respectively. Results Except for physical functioning, patients of PHP group had reduced scores in all other subdomains of SF36v2 compared to healthy controls ( P<0.05) . Comparing to nHPT patients, PHP patients had a higher score in social functioning, while no difference was found in other subdomains of SF36v2. Grip strength and RCS tests were similar in PHP patients and healthy controls. Conclusions Comparing to healthy controls, patients with PHP still had impaired QoL despite regular management, no significant difference of upper and lower limb muscle strength was found between PHP group and healthy controls.

Objective:To evaluate the clinical value of nanopore targeted sequencing (NTS) in pathogens detection in urinary tract by comparing the results of different tests performed on the same urine sample.Methods:The results of NTS and urine culture test collected from 326 patients in the Department of Urology of People's Hospital of Wuhan University from July 2020 to June 2021 were retrospectively analyzed. There were 224 males and 102 females. The average age was (56.88 ± 14.58)years old. χ 2 test and Student’s test and Wilcoxon's sign rank test were used to analyze the differences of the pathogen detection rate, pathogen types results and detection time consuming between NTS and urine culture. The clinical value of the NTS in rapid detection of urinary pathogens was evaluated. Results:Among 326 hospitalized patients, the urinary tract microbes’ detecting rate of NTS was significantly higher than that of urine culture[67.80%(221/326)vs. 23.93%(78/326), χ2=130.25, P<0.01]. The uropathogens detecting rate of NTS was significantly higher than that of urine culture[54.29%(177/326)vs. 23.31%(76/326), χ2=38.95, P<0.01]. The number of urinary tract microbes detected by NTS was significantly higher than that of urine culture ( Z=11.49, P<0.01), the number of uropathogens was significantly higher than that of urine culture ( Z=9.67, P<0.01). The detection time of NTS and urine culture positive samples was (24.29±2.65) h and (49.28±11.30) h, the difference was statistically significant ( t =39.48, P<0.01). The results obtained by using NTS and urine culture were consistent in 135 (41.41%) samples. In 150 (46.01%) samples, NTS could detect the urinary tract microbes while urine culture cannot find, of which 112 cases (34.36%) were uropathogenic. In 27 cases (8.28%), more pathogens were detected by NTS except those from urine culture. In 6 cases (1.84%) re-detecting NTS after antibiotic therapy, the number of reads of primary uropathogen decreased gradually with the growth of colonizing bacteria or opportunistic pathogens appeared in the end. Re-examinations of urine culture could verify the results of NTS detection on admission in 5 cases (1.53%). NTS in 2 cases (0.61%) could cover the uropathogens of subsequent several urine cultures. Conclusions:NTS has the advantages of rapid, sensitive and comprehensive detection of urinary tract infection pathogens. When urine culture is not yet reported or even negative, NTS already has a certain clinical reference value and can be used as an effective supplement to urine culture, which is conducive to the comprehensive judgment of the patient's condition.

Objective:To investigate the availability and safety of a domestic disposable digital flexible cystoscope compared with a reusable Olympus digital flexible cystoscope in cystoscopy and removal of double J stent.Methods:From August 2018 to March 2019, patients were enrolled in this prospective, open, multicenter, randomized, parallel positive controlled clinical trial study, which were from department of Urology in Renmin Hospital of Wuhan University, the First Affiliated Hospital of Xiamen University and the First Affiliated Hospital of Guangzhou Medical University. The experimental group and control group were assigned into a 1∶1 ratio by random table method. Inclusion criteria included age≥18 years and have indications for cystoscopy or removal of double J stent. Exclusion criteria included patients having acute genitourinary tract infection, having tuberculous bladder contracture, bladder capacity less than 50ml, having urethrostenosis, female menstrual period, pregnancy and lactation, having difficulty for lithotomy position, having serious cardio-cerebrovascular disease and liver or kidney dysfunction. A domestic disposable digital flexible cystoscope was adopted in the experimental group, whereas a reusable Olympus digital flexible cystoscope was used in the control group. Acceptability of image was defined as primary availability indicator, while success rate of working and performance score were defined as secondary availability indicators and mean operating time was calculated for cystoscopy only and cystoscopy plus removal of double J stent respectively, yet rate of adverse event as well as rate of equipment defects were sorted as safety indicators.Results:A total of 188 cases which were listed in per protocol set completed the clinical trial study successfully. There were 95 cases in the experimental group and 93 cases in the control group. Acceptability of image was 93.68%(89/95) and 96.77%(90/93) respectively in two groups( P=0.52). Success rate of working was 100.00%(95/95) and 98.92%(92/93) respectively in two groups ( P=0.49). Performance score was 14.41±0.93 and 14.56±0.84 respectively in two groups ( P=0.23). Mean operating time (MOT) only for cystoscopy was (15.3±2.6) min and (15.4±3.3)min respectively in two groups ( P=0.93), while MOT for cystoscopy plus removal of double J stent was (21.0±3.2) min and (21.7±3.9) min respectively in two groups ( P=0.69). Rate of adverse event was 8.42%(8/95) and 9.68%(9/93) respectively in two groups( P=0.76). There was no equipment defects in both groups. Conclusions:There is no statistical difference in acceptability of image, success rate of working, performance score, mean operating time for cystoscopy or removal of double J stent, rate of adverse events and rate of equipment defects. A domestic disposable digital flexible cystoscope has shown non-inferiority in the availability and safety compared with a reusable Olympus digital flexible cystoscope.

Objective: To investigate the association of GNA11 gene polymorphisms with the risk of adult-onset non-surgical hypoparathyroidism (Ns-HypoPT). Methods: Genotyping of GNA11 single nucleotide polymorphisms (SNPs) (rs28685098, rs4806907, rs11084997 and rs78003011) was carried out in 203 patients and 209 healthy participants by sequenom MassArray iPLEX System. These SNPs are located in promoter and 3′untranslated region (3′UTR) of GNA11 gene, respectively. Results: Allele and genotype frequencies of rs11084997 in patients were significantly different from those of controls (genotype GG:60.5% vs. 49.8%, GC: 35.5% vs. 41.6%, CC: 4.0% vs. 8.6%, P=0.038; G allele 78.3% vs. 70.6%, C allele 21.7% vs. 29.4%, P=0.012), and the C allele of rs11084997 carriers had a lower risk to develops Ns-HypoPT in additive and dominant genetic models [OR=0.382 (0.160-0.915), 0.647 (0.437-0.957)]. CC-Haplotype formed by the minor alleles of rs4806907 and rs11084997 was associated with a decreased risk of Ns-HypoPT in additive, dominant and recessive genetic model [OR=0.317 (0.126-0.801), 0.640 (0.430-0.952), 0.367 (0.148-0.912)]. Conclusion The minor allele C of rs11084997 in GNA11 gene promoter was associated with decreased risk of Ns-HypoPT in Chinese population.

The anterior pituitary gland drives highly conserved physiologic processes in mammalian species. These hormonally controlled processes are central to somatic growth, pubertal transformation, fertility, lactation, and metabolism. Current cellular models of mammalian anteiror pituitary, largely built on candidate gene based immuno-histochemical and mRNA analyses, suggest that each of the seven hormones synthesized by the pituitary is produced by a specific and exclusive cell lineage. However, emerging evidence suggests more complex relationship between hormone specificity and cell plasticity. Here we have applied massively parallel single-cell RNA sequencing (scRNA-seq), in conjunction with complementary imaging-based single-cell analyses of mRNAs and proteins, to systematically map both cell-type diversity and functional state heterogeneity in adult male and female mouse pituitaries at single-cell resolution and in the context of major physiologic demands. These quantitative single-cell analyses reveal sex-specific cell-type composition under normal pituitary homeostasis, identify an array of cells associated with complex complements of hormone-enrichment, and undercover non-hormone producing interstitial and supporting cell-types. Interestingly, we also identified a Pou1f1-expressing cell population that is characterized by a unique multi-hormone gene expression profile. In response to two well-defined physiologic stresses, dynamic shifts in cellular diversity and transcriptome profiles were observed for major hormone producing and the putative multi-hormone cells. These studies reveal unanticipated cellular complexity and plasticity in adult pituitary, and provide a rich resource for further validating and expanding our molecular understanding of pituitary gene expression programs and hormone production.

Objective: To investigate the effectiveness and safety of high-dose native vitamin D versus active vitamin D by retrospective analysis of clinical data in patients with non-surgical hypoparathyroidism (ns-HP) in our hospital. Methods: ns-HP patients with stable therapeutic schedule in recent three years were included. According to the vitamin D agents used, patients were divided into three groups: active vitamin D group, native vitamin D group, and mixed vitamin D group. The effectiveness was evaluated by analysis of markers including post-treatment serum calcium, incidence of hypocalcemia, hypocalcemic symptoms and signs. The safety was evaluated in various groups by analyzing incidences of hypercalcemia and hypercalciuria, glomerular filtration rate, percentage of thiazide diuretic use, nephrocalcinosis or renal stone. Results: Patients in active vitamin D group were more likely to experience episodes of hypocalcemia compared with those in native group (32.94%±21.46% vs 24.86%±10.1%, P<0.05). No significant differences in other indexes for assessing effectiveness and safety were found among three groups (P>0.05). Conclusions Under the circumstance of regular follow-up, both high-dose native vitamin D and active vitamin D could treat ns-HP effectively and safely. Native vitamin D may be better in maintaining eucalcemia and reducing incidence of hypocalcemia compared with active vitamin D.
