RESUMO
Objective: To understand the situation and epidemic characteristics of injury deaths among children aged 5 to 24 years in Jiangsu Province from 2012 to 2021 and the trend of annual changes. Methods: The main injury mortality data of children and adolescents was collected, and the crude and standardized mortality rates of road traffic accidents, drowning, suicide, and accidental falls among children and adolescents over a decade and the annual average percentage of change (AAPC) were calculated. The main injury mortality characteristics and trends of children and adolescents of different age groups and genders were analyzed. Results: The total number of injury deaths among 5 to 24 adolescents in Jiangsu Province was 16 052, with a standardized mortality rate of 9.58/100 000. There was no significant trend in the overall standardized mortality rate of injuries (AAPC=-3.450%, P=0.055). The standardized mortality rate of road traffic injuries among children and adolescents showed a decreasing trend over the past decade, with statistical significance (AAPC=-9.406%, P<0.001). The standardized suicide mortality rate showed an upward trend over the past decade, with statistical significance (AAPC=9.000%, P=0.001). The overall injury mortality rate showed an upward trend with age. Suicide rates in males and females were on the rise and both have statistical significance (AAPC=9.420% and AAPC=9.607%, both P<0.05). The standardized mortality rates of female traffic accidents, drowning, and male traffic accidents showed a decreasing trend and were statistically significant (AAPC for female traffic accidents=-7.364%, AAPC for female drowning=-5.352%, and AAPC for male traffic accidents=-10.242%, all P<0.05). The standardized mortality rate of urban and rural traffic accidents showed a decreasing trend and was statistically significant(AAPC=-7.899% and AAPC=-9.421%, both P<0.001). The standardized suicide mortality rate showed an upward trend and statistical significance (AAPC=11.009% and AAPC=7.528%, both P<0.05). Conclusions: The overall injury situation of children and adolescents in Jiangsu Province improved in the past decade from 2012 to 2021, but the suicide mortality rate was on the rise. It is necessary to focus on the mental health issues of this age group and to strengthen the prevention and control of suicide among children and adolescents, in Jiangsu.

Objective: To evaluate the hemostatic efficacy, safety and immunogenicity of recombinant human thrombin in the treatment of liver wounds that still ooze after conventional surgical hemostasis. Methods: A multicenter, stratified randomized, double-blind, placebo-controlled phase â ¢ trial with a planned enrollment of 510 subjects at 33 centers, with a 2â¶1 randomization to the thrombin group versus the placebo group. An interim analysis will be conducted after approximately 70% of the subjects have completed the observation period. The primary efficacy endpoint was the rate of hemostasis within 6 minutes at the point of bleeding that could be evaluated. Safety analysis was performed one month after surgery, and the positive rates of anti-drug antibody (ADA) and neutralizing antibody were evaluated. Results: At the interim analysis, a total of 348 subjects had been randomized and received the study drug (215 were male and 133 were female). They were aged 19-69 (52.9±10.9)years. Among them, 232 were in the thrombin group and 116 were in the placebo group, with balanced and comparable demographics and baseline characteristics between the two groups. The hemostasis rate at 6 minutes was 71.6% (95%CI:65.75%-77.36%) in the thrombin group and 44.0% (95%CI: 34.93%-53.00%) in the placebo group, respectively (P<0.001). No grade≥3 drug-related adverse events and no drug-related deaths were reported from the study.No recombinant human thrombin-induced immunologically-enhanced ADA or immunologically-induced ADA was detected after topical use in subjects. Conclusion: Recombinant human thrombin has shown significant hemostatic efficacy and good safety in controlling bleeding during liver resection surgery, while also demonstrating low immunogenicity characteristics.

Objective: To obtain the diversity and abundance of fast-growing bacteria in the surface water of the northeast coast of Hainan Island in China, different cultivation methods were employed. This study also aims to provide a reference for isolating bacterial samples from seawater sources and preventing marine-derived pathogens. Methods: Based on the principles of taxonomic design, surface seawater samples were collected from six locations along the northeast coast of Hainan Island in China in March, June, October, and December 2021. Then, bacterial enrichment was performed based on traditional cultivation methods for Salmonella, Vibrio, Burkholderia pseudomallei, Actinomycetes, and general marine bacteria. After that, bacterial species identification was conducted by 16S rDNA amplicon sequencing and metagenomic sequencing. Results: A total of 1 151 fast-growing cultivable bacteria belonging to 66 genera and 213 species were identified using five different culture protocols. In different cultivation protocols, Bacillus and Klebsiella demonstrated extensive discriminatory advantages and ranked among the top genera in terms of abundance. Protocol 1 had Escherichia, Klebsiella, and Citrobacter as dominant genera. Pathogenic bacteria detected by protocol 1 included Klebsiella pneumoniae and Escherichia coli, with 37 and 29 strains respectively, while Salmonella enterica was uniquely detected with seven isolates. Proteus, Enterococcus, and Providencia were the dominant genera in protocol 2, and Proteus mirabilis was the most abundant pathogenic bacteria detected with 66 isolates. Vibrio cholerae was uniquely detected with six isolates at a higher abundance. Klebsiella, Escherichia, and Acinetobacter were the dominant genera in protocol 3, and Klebsiella pneumoniae was the most abundant pathogenic bacteria detected with 53 isolates, while Acinetobacter nosocomialis was uniquely detected with seven isolates. Vibrio and Pseudoalteromonas were the dominant genera in protocol 4, and they showed advantages in isolating and cultivating Marine-derived Vibrio. Exiguobacterium, Staphylococcus, and Bacillus were the dominant genera in protocol 5. Bacillus cereus and Lactococcus lactis were the most abundant pathogenic bacteria detected with 20 and 15 isolates, respectively, while Lactococcus lactis was uniquely detected at higher abundance. Metagenomic sequencing showed that Klebsiella pneumoniae was significantly dominant with a gene abundance of 51.11%, followed by Alcanivorax sp. at 12.57%. Conclusion: The surface water of the northeast coast of Hainan Island in China exhibits a rich diversity of bacteria, with Klebsiella pneumoniae being highly abundant in the studied area. Different cultivation methods demonstrate distinct selective advantages in culturing bacterial genera and pathogens. Therefore, it is necessary to optimize cultivation conditions for specific marine bacteria.

Objective: To describe gastric cancer incidence in Suzhou cohort, explore the environmental risk factors of gastric cancer in Suzhou, and provide appropriate suggestions for gastric cancer prevention and control. Methods: The participants were from the Suzhou cohort of China Kadoorie Biobank. Baseline survey was conducted from 2004 to 2008, followed by long-term follow-up until December 31, 2013. After the exclusion of those who had been previously diagnosed with peptic ulcer and malignant tumor reported at baseline survey and gastric cancer within six months after enrollment, a total of 50,136 participants were included. Cox proportional risk models were used to identify risk factors of gastric cancer and their hazard ratios in Suzhou. The effect modifications of gender on the association between risk factors and gastric cancer were analyzed. Results: In the follow-up of 7.19 years (median), 374 gastric cancers cases occurred. The standardized incidence was 94.57 per 100 000 person-years. Multivariate Cox proportional risk model analysis found that age (10 years old as a age group, HR=2.20, 95%CI: 1.92-2.53, P<0.001), current smoking (HR=1.84, 95%CI: 1.10-3.07 P=0.020), consumption of preserved vegetables weekly (HR=2.28, 95%CI: 1.28-4.07, P=0.005) and daily (HR=2.05, 95%CI: 1.16-3.61, P=0.013) were risk factors for gastric cancer. Female (HR=0.44, 95%CI: 0.25-0.76, P=0.003) and refrigerator use (10 years as a limit, HR=0.85, 95%CI: 0.74-0.97, P=0.016) were protective factors for gastric cancer. Further analysis showed that there was heterogeneity between males and females in the association between refrigerator use years and the incidence of gastric cancer (P=0.009), and there was an interaction effect between gender and refrigerator use on the incidence of gastric cancer (P=0.010). Conclusions: The incidence of gastric cancer in Suzhou cohort was high. The risk factors of gastric cancer varied. There was a synergistic interaction effect between gender and refrigerator use years on the incidence of gastric cancer.

Objective: To estimate physical activity level in residents in Suzhou and explore the association between community environment and physical activity level in local residents. Methods: Through multistage stratified random sampling, residents aged 25-64 years in Suzhou were surveyed by face-to face interview in 2017. Physical activity levels were assessed by the international physical activity questionnaire-long version (IPAQ-L). Perceptions of community environment were assessed by Neighborhood Environment Walkability Scale-Abbreviated (NEWS-A). Results: Among the local residents surveyed in Suzhou,the median of weekly total physical activity level was 3 610.42 MET-min/w. The level of occupational physical activity was higher than that of transportation, household and leisure-time related physical activity levels. After controlling for socio-demographic factors, public service access was negatively associated with the overall physical activity level (OR=0.522,95%CI:0.329-0.830), land-use mix-diversity was negatively associated with the level of occupational physical activity level (OR=0.701,95%CI: 0.492-0.999), infrastructure of walk and cycle ways was positively associated with occupational physical activity level (OR=1.603,95%CI:1.004-2.559); traffic hazards were negatively associated with the transportation physical activity level (OR=0.642,95%CI: 0.416-0.990); residential building density was positively associated with leisure-time physical activity level (OR=1.001,95%CI: 1.000-1.002), and the perceptions level of community environment were positively associated with the occupational, transportation, household and overall physical activity levels (OR=1.889,95%CI: 1.176-3.033;OR=1.671,95%CI: 1.120-2.495;OR=1.775,95%CI: 1.143-2.756;OR=1.593,95%CI: 1.079-2.350). Conclusion: Improving infrastructure of walk and cycle ways and beautifying community environment play an important role in increasing the physical activity level of the residents.

We studied the correlations between egg geometrical parameters (i.e., egg shape index, sphericity, geometric mean diameter, surface area, and volume) and eggshell qualities, or the organic matrix in eggshell. Eggs were collected from 5 poultry breeds belonging to 3 species (commercial Hy-line Brown Chicken, Shaoxing Duck, Jinding Duck, Taihu Goose, and Zhedong White Goose). The geometrical parameters showed high variation among 3 species of poultry, and even between breeds in the same species. The five geometrical parameters were grouped into 2 sets, one contained shape index and sphericity, the other comprised geometric mean diameter, surface area, and volume. The parameters in the same set can be perfectly fitted to one another. Egg weight, shell membrane weight, and calcified shell weight were significantly correlated with geometric mean diameter, surface area, and volume. In accordance with false discovery rate-adjusted P value, both shell membrane relative weight and calcified shell thickness showed no significant correlations with any of the geometrical parameters. However, the correlations between geometrical parameters and other shell variables (calcified shell weight, shell relative weight, calcified shell thickness uniformity, and eggshell breaking strength) depend on breed. Both constitutive proportions and percentage contents of 3 eggshell matrix components (acid-insoluble, water-insoluble, and both acid and water facultative-soluble matrix) had no effects on egg shape and size. The correlations between the amounts of various shell matrix, egg shape and size depend on breed or species. This study provides a methodology and the correlation between geometrical parameters and eggshell qualities, and between geometrical parameters and organic matrix components in calcified shells.

OBJECTIVE: Many studies have been published recently on the characteristics of the clinical manifestations of COVID-19 in children. The quality scores of literature are different, and the incidence of clinical manifestations and laboratory tests results vary greatly. Therefore, a systematic retrospective meta-analysis is needed to determine the incidence of the clinical manifestations of COVID-19 in children. MATERIALS AND METHODS: Data from databases, such as PubMed, Web of science, EMBASE, Johns Hopkins University, and Chinese databases were analysed from January 31, 2020 to October 20, 2020. High-quality articles were selected for analysis based on a quality standard score. A meta-analysis of random effects was used to determine the prevalence of comorbidities and subgroup meta-analysis to examine the changes in the estimated prevalence in different subgroups. RESULTS: Seventy-one articles involving 11,671 children were included in the study. The incidence of fever, respiratory symptoms, gastrointestinal symptoms, asymptomatic patients, nervous system symptoms, and chest tightness was 55.8%, 56.8%, 14.4%, 21.1%, 6.7%, and 6.1%, respectively. The incidence of multisystem inflammatory syndrome was 6.2%. Laboratory examination results showed that lymphocytes decreased in 12% and leukocytes decreased in 8.8% of patients, whereas white blood cells increased in 7.8% of patients. Imaging showed abnormalities in 66.5%, and ground-glass opacities were observed in 36.9% patients. Epidemiological history was present in 85.2% cases; severe disease rate was 3.33%. The mortality rate was 0.28%. CONCLUSIONS: The clinical symptoms of COVID-19 in children are mild, and laboratory indicators and imaging manifestations are atypical. While screening children for COVID-19, in addition to assessing patients for symptoms as the first step of screening, the epidemiological history of patients should be obtained.

OBJECTIVE: Given that FK506 binding protein 51 (FKBP51) is upregulated in multiple cancers, we designed the present study to characterize its role as well as underlying regulatory mechanisms in glioma in the presence and absence of the chemotherapeutic carmustine (BCNU). MATERIALS AND METHODS: Through lentiviral overexpression and shRNA knockdown of FKBP51, we examined the effects on BT325 glioma cell proliferation, migration and invasion using quantitative reverse transcription PCR (qRT-PCR), CCK-8 assay, flow cytometry, and transwell assay. RESULTS: The upregulation of FKBP51 resulted in significantly decreased BT325 cell proliferation and cell viability, cell cycle arrest, reduced BCNU chemosensitivity and AKT pathway inactivation. However, FKBP51-overexpressed BT325 cells showed enhanced migration and invasion, which was supported by corresponding increase in phosphorylated IKKα (p-IKKα), MMP-2, and MMP-9 levels, as well as increased NF-κB p65 nuclear translocation. By contrast, FKBP51-suppressed BT325 cells showed excessive proliferation and BCNU resistance due to increased p-AKT activation and attenuated migration and invasion. CONCLUSIONS: We demonstrated that the effects of FKBP51 on BT325 glioma cell proliferation, migration, invasion and BCNU chemosensitization are modulated via the AKT and NF-κB pathways. Furthermore, our findings suggest the potential of FKBP51 as a prognostic glioma biomarker and an indicator of patient response to chemotherapy.

From 1987 to 2017, cardiovascular disease (CVD) had been ranking the first cause of death in Suzhou, and the mortality rate showed an upward trend annual percentage changes (APC=0.62%, P=0.001), while the standardized mortality rate showed a downward trend (APC=-2.65%, P<0.001). The probability of premature death of CVD declined consistently from 7.06% in 1987 to 2.00% in 2017 (APC=-4.45%, P<0.001). When the life expectancy was set at 70, the potential years of life lost rate (PYLLR) decreased from 6.35 in 1987 to 3.30 in 2017, and the standardized PYLLR decreased from 7.30 to 2.68. When the life expectancy was set at 75, the PYLLR decreased from 10.12 to 5.19, and the standardized PYLLR decreased from 11.44 to 3.88. With the increase of years, all PYLLR and standardized PYLLR showed a significantly downward trend (APC=-2.51%--3.89%, P<0.001).

Objective: To study the safety and efficacy of topography-guided customized excimer laser subepithelial ablation combined with accelerated collagen cross-linking technique in treatment of early keratoconus. Methods: Ninteen patients(20 eyes) (13 males 14 eyes, and 6 females 6 eyes), aged 12 to 44 years (24.7±8.0) were diagnosed as keratoconus by three-dimensional corneal topography and tomography, clinical history and examinations, and classified as KC1~KC3. Based on the classical excimer laser subepithelial keratomileusis (LASEK) method, topography guided laser ablation was performed with an excimer laser system (WaveLight EX500). After laser ablation, the corneal stromal bed was immersed with 0.1% riboflavin for 10 minutes, and then was irradiated by ultraviolet light (Avedro KXL) at 30 mW/cm(2) for 4 minutes. All the patients were followed up for more than 12 months. The uncorrected visual acuity (UCVA), diopter, best corrected visual acuity (BSCVA), corneal topography, central corneal endothelial cell density (ECD), hexagonal cell percentage (HEX), coefficient of variation (CV) and other indicators were observed. For normal distribution variables, Dunnett-t test was used before and after operation, and Wilcoxon test was used for variables with abnormal distribution. And the complications were recorded. Results: There was no loss of BSCVA at 12 months postoperatively, 20% of the eyes had no change of BSCVA, and 15% of the eyes gained 1 line of BSCVA, 15% of the eyes gained 2 lines of BSCVA, 50% of the eyes gained 3 lines and more of BSCVA. There was no significant difference in UCVA, BSCVA, manifest refractive spherical equivalent (MRSE) and the cylinder at 3 months postoperatively (P>0.05). The BSCVA were significantly improved at 6 and 12 months postoperatively compared with those before operation (t=3.095, 3.079, <0.05). Although there was no significant difference in UCVA and MRSE, the cylinder was significantly reduced at 6 and 12 months postoperatively (t=-2.890, -2.435, P<0.05). Apex curvature (Kapex) and mean pupil power (MPP) within 4.5mm of central cornea decreased significantly (Z=-2.903, P<0.01; Z=-2.667, P<0.01). Even though the thinnest corneal thickness decreased from pre-operational (461.9±31.1) µm to post-operational (416.6±27.0) µm (Z=-3.059, P<0.01), the cornea became regular with keratometric asymmetry index of anterior corneal surface decreased (Z=-2.667, P<0.01). The corneal optical quality parameters were improved. There was no significant difference in ECD, HEX and CV at 12 months postoperatively (P>0.05). Twelve months after operation, grade 0, 0.5, 1 and 2 haze were seen on 20%, 55%, 20% and 5% corneas respectively. Conclusions: The topography guided excimer laser ablation combined with accelerated corneal collagen cross linking is safe and effective in treatment of early stage keratoconus. It can significantly improve corneal regularity while preventing keratoconus progression, so as to improve the best corrected visual acuity postoperatively. (Chin J Ophthalmol, 2019, 55: 904-910).

Objective: To investigate the microbiological test, antibiotic sensitivity and surgical treatment of periprosthetic joint infection(PJI) cases in post total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. Methods: A retrospective cross-sectional survey was conducted on 318 patients who underwent THA or TKA in 9 clinical centers in Beijing from January 2014 to December 2016.The data of microbiology, antibiotic sensitivity and surgical treatment were collected.The average age of patients was (62.3±13.1) years old (range: 21-86 years old), including 145 males and 173 females.The body mass index was (25.6±3.8) kg/m (2) (range: 15.6-38.1 kg/m(2)). Results: In total, 318 patients had microorganisms detected by periprosthetic tissue culture or synovial fluid culture, 209 cases (65.7%) had Gram-positive bacteria, 29 cases (9.1%) had Gram-negative bacteria, 10 cases (3.1%) had fungi, 3 cases (0.9%) had non-tuberculous mycobacteria, 72 cases (22.6%) were negative, 69 cases (21.7%) had methicillin-resistant bacteria. The antibiotic sensitivity results showed that the overall resistance rate of penicillin, cefuroxime, amoxicillin+clavulanic acid was 79.9%, 69.9%, and 68.1%, respectively; meropenem, vancomycin, and linezolid resistance rate was 0. For the treatment methods of hip and knee PJI, two-stage revision surgery acounted for 72.9% (108/148) and 64.1% (109/170), respectively. One-stage revision surgery accounted for 21.6% (32/148) and 7.6% (13/170), and open debridement surgery accounted for 4.7%(7/148) and 26.4% (45/170). Conclusions: Gram-positive bacteria was still the main pathogen of PJI.The methicillin-resistant bacteria and rare bacteria should be payed attention to. The Majority of hip and knee PJI cases were treated by two-stage revision surgery.

Objective: To investigate the risk factors affecting the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), and establish a new scoring model to predict the short-term prognosis of patients. Methods: This study enrolled 222 patients with HBV-ACLF. According to their clinical outcomes during hospitalization and 90 days after discharge, they were divided into survival and death group. Clinical data were collected to calculate the Child-Turcotte-Pugh (CTP), model for end-stage liver disease (MELD), albumin-bilirubin (ALBI), and age-bilirubin-international normalized ratio-creatinine (ABIC) scores for prognosis. Multivariate logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients. Cox regression model was used to establish a new prediction model. Area under the receiver operating characteristic curve was used to calculate short-term prognostic value of the models. K-M survival curve was used to predict the prognosis of patients. Results: CTP and ABIC scores were independent risk factors for 90-day mortality in HBV-ACLF patients, and the risk of death from liver failure had increased with increase of score. Cox regression model established a new predictive model CTP-ABIC = 0.551 × CTP + 0.297 × ABIC. Area under the receiver operating characteristic curve of all three scoring models (CTP, ABIC and CTP-ABIC) were 0.878, 0.829, 0.927, respectively. CTP-ABIC score was superior to the CTP and ABIC score (P value < 0.001). Patients with CTP-ABIC score ≥9.08 had higher mortality rate than patients with CTP-ABIC score < 9.08, and the difference was statistically significant (P < 0.001). Conclusion: All three scoring systems can predict short-term prognosis in patients with HBV-ACLF, but the accuracy of CTP-ABIC is superior.

BACKGROUND: The efficacy of final kissing balloon (FKB) inflation in one-stent techniques for bifurcation lesions is controversial. The goal of the present study was to investigate the impact of FKB on long-term clinical outcomes in one-stent strategies. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was undertaken through August 2017. The primary outcome was major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction, and target lesion revascularization. Overall hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the random-effects model. RESULTS: Ten studies comprising 7364 patients treated with a one-stent technique were included in the analysis. Overall, FKB did not demonstrate a significant reduction in MACE compared with non-FKB in both randomized trials (HR: 1.13; 95% CI: 0.65-1.98) and observational studies (HR: 0.86; 95% CI: 0.61-1.20). The risk of cardiac death (HR: 0.89; 95% CI: 0.53-1.49), myocardial infarction (HR: 0.76; 95% CI: 0.53-1.09), and target lesion revascularization (HR: 0.96; 95% CI: 0.74-1.23) was also similar in both groups. CONCLUSION: FKB may not be mandatory and a selective FKB strategy might be more justified in one-stent techniques for bifurcation lesions.

INTRODUCTION: Women are entering the subspecialty of pediatric urology at an accelerated rate. Gender differences affecting fellowship and job selection have been identified in other fields of medicine. OBJECTIVE: The objective of this study was to understand gender differences in pediatric urology fellowship and job selection and how they may affect the workforce. STUDY DESIGN: A 47-question electronic survey consisting of questions regarding demographics, residency training, and factors influencing fellowship and job selection was distributed to current fellows and recent graduates in pediatric urology in May 2017. RESULTS: A total of 111 recent and current fellows were contacted, and 72% completed the survey (55% female [F] and 45% male [M]; 61% current fellows and 39% recent fellows). Respondents rated factors important in choosing pediatric urology on a scale of 1-5 (1, not important and 5, extremely important), and the top three for both genders were 1-working with children, 2-influential mentors, and 3-bread and butter cases such as inguinal orchiopexy. During residency, 93% of respondents reported having influential mentors in pediatric urology. However, mentorship was more important in fellowship choice for males than females (3.6 F, 4.1 M; P-value = 0.048), and 45% reported having only male mentors. Rating factors important in job choice on a scale of 1-5, respondents reported the top factors as 1-rapport with partners/mentorship (4.5), 2-geography/family preferences (4.3), and 3-participation in mentoring/teaching (3.8). Although most job selection criteria were rated similarly between genders, females rated call schedule higher than males (3.5 F, 2.9 M, P-value = 0.009). Although most females and males (79% of F, 78% of M, P-value = 0.868) sought primarily academic positions, a smaller proportion of females accepted academic positions (52% of F, 72% of M, P-value 0.26), and females reported lower satisfaction regarding the availability of jobs on a scale of 1-5 (1, very dissatisfied and 5, very satisfied; 3.1 F, 3.7 M; P-value = 0.034), particularly in academic positions (3.1 F, 3.7 M; P-value = 0.06). This difference was more pronounced in current fellows than recent graduates and may represent a worsening trend. CONCLUSION: Although significant gender differences in fellowship and job selection may exist in other fields, we found that women and men choose pediatric urology fellowships and jobs using similar criteria, which include work-life balance. Gender differences exist in the influence of mentors, indicating a need for more female mentors. While men and women sought similar types of jobs, women were less satisfied with the availability of jobs, particularly academic jobs, than men, which warrants further investigation.

OBJECTIVE: To investigate the expression level of serum matrix metalloproteinase 3 (MMP3) in early rheumatoid arthritis (ERA) patients with normal C-reaction protein (CRP) or erythrocyte sedimentation rate (ESR), and the significance in disease assessment. METHODS: In the study, 133 cases of early RA patients, 25 osteoarthritis (OA) patients and 60 healthy controls in Peking University People's Hospital from 2011 to 2015 were included. The RA patients were further divided into 4 groups according to levels of CRP and ESR: 88 patients with increased CRP and increased ESR, 15 patients with normal CRP and normal ESR, 17 patients with normal CRP but increased ESR, and 13 patients with increased CRP but normal ESR. All the clinical information of the patients was collected, and the serum MMP3 levels of both patients and healthy controls were detected by enzyme-linked immune sorbent assay (ELISA). RESULTS: The serum MMP3 level of RA patients with normal CRP and/or normal ESR [(72.89±6.34) µg/L] was obviously higher than that of OA patients [(42.87±4.14) µg/L] (P=0.002) and healthy controls [(31.62±2.88) µg/L] (P<0.001). The serum MMP3 levels of the patients with normal CRP and normal ESR [(47.04±9.64) µg/L] were higher than those of the healthy controls, and there was statistical significance between the two groups (P<0.05). The serum MMP3 levels of the patients with increased CRP but normal ESR [(94.18±9.11) µg/L] and the patients with normal CRP but increased ESR [(79.42±10.60) µg/L] were both higher than those of the OA patients and healthy controls, and there was obvious statistical difference (P<0.05). In the early RA patients with normal CRP and/or normal ESR, the serum MMP3 level was positively correlated with the CRP level (r=0.336, P=0.024). The positive rate of MMP3 in the patients with normal CRP and/or normal ESR was 44.44%, higher than the positive rate of CRP (28.89%) and the positive rate of ESR (37.78%). In these early RA patients, the positive rate was 52.94% in the patients with normal CRP but increased ESR and 53.85% in the patients with increased CRP but normal ESR. CONCLUSION: The detection of the serum MMP3 level was significant in the assessment of early RA patients within 2-year duration who had normal CRP or ESR value.

OBJECTIVE: To investigate the effect of transesophageal echocardiography (TEE) in the surgical treatment of tetralogy of Fallot. PATIENTS AND METHODS: 98 patients with tetralogy of Fallot received and cured by Zhengzhou Cardiovascular Hospital (Zhengzhou No. 7 People's Hospital) from January 2015 to January 2017 were selected as the study objects. All patients were examined by TEE before surgery, and the pulmonary artery index (PAI) and pulmonary vein index (PVI) were measured, so as to analyze the effect of TEE in the surgical treatment of tetralogy of Fallot. Among the 98 patients, 12 patients were diagnosed with intensive care unit (ICU) retention, 23 patients were diagnosed with respirator assisted respiration extension, 8 patients were diagnosed with low cardiac output syndrome, and 10 patients were diagnosed with respiratory tract infection, which indicated that TEE could diagnose conditions after radical operation of tetralogy of Fallot. RESULTS: The calculation results showed that the PAI was (171.37±58.39) mm2/m2 and the PVI was (282.46±54.37) mm2/m2. The Pearson correlation analysis showed that the correlation between them was good (r=0.821, p<0.001). TEE had good specificity and sensitivity in the diagnosis of respirator assisted respiration extension, ICU retention, and low cardiac output syndrome after radical surgery of tetralogy of Fallot. CONCLUSIONS: TEE can predict the occurrence of respirator assisted respiration extension, ICU retention and low cardiac output syndrome of patients after radical surgery by evaluating the PAI and PVI of patients with tetralogy of Fallot.

The kinetics of serum hepatitis B surface antigen (HBsAg) during the natural history of hepatitis B virus (HBV) infection has been studied, but the factors affecting them remain unclear. We aimed to investigate the factors affecting HBsAg titres, using data from multicentre, large-sized clinical trials in China. The baseline data of 1795 patients in 3 multicentre trials were studied, and the patients were classified into 3 groups: hepatitis B early antigen (HBeAg)-positive chronic HBV infection (n = 588), HBeAg-positive chronic hepatitis B (n = 596), and HBeAg-negative chronic hepatitis B (n = 611). HBsAg titres in the different phases were compared, and multiple linear progression analyses were performed to investigate the implicated factors. HBsAg titres varied significantly in different phases (P = .000), with the highest (4.60 log10 IU/mL [10%-90% confidence interval: 3.52 log10 IU/mL-4.99 log10 IU/mL]) in patients with HBeAg-positive chronic HBV infection. In all phases, age and HBV DNA were correlated with serum HBsAg level. In HBeAg-positive chronic hepatitis B patients, a negative correlation between HBsAg titres and fibrosis stage was observed. Alanine amonitransferase or necroinflammatory activity was also correlated with HBsAg titres in HBeAg-negative chronic hepatitis B patients. In conclusion, decreased HBsAg titres may be associated with advancing fibrosis in HBeAg-positive chronic hepatitis B patients or increased necroinflammation in those with HBeAg-negative chronic hepatitis B. Our findings may help clinicians better understand the kinetics of HBsAg and provide useful insights into the management of this disease.

BACKGROUND: Childhood asthma comprises different phenotypes with complex pathophysiology. Different asthma phenotypes evoke various clinical symptoms and vary in their responses to treatments. METHODS: We applied k-means clustering algorithm of twelve objective laboratory tests among 351 asthmatic children enrolled in the Taiwanese Consortium of Childhood Asthma Study (TCCAS). We constructed gene expression profiles of peripheral blood mononuclear cells (PBMC) from children with different asthma phenotypes. RESULTS: Five distinct phenotypes of childhood asthma were identified and can be characterized by either eosinophil-predominant or neutrophil-predominant inflammatory characteristics. In the gene expression profile analysis, significant differences were noted for neutrophil-predominant asthma, compared with samples from all the other asthma phenotypes. The vast majority of the differentially expressed genes in neutrophil-predominant asthma was associated with corticosteroid response. From an independent inhaled corticosteroid (ICS) response cohort, we also found neutrophils could be activated in this severe asthma phenotype and neutrophil-predominant asthma may be associated with corticosteroid nonresponsiveness. CONCLUSION: Phenotype clustering of childhood asthma can be helpful to identify clinically relevant patients and reveal different inflammatory characteristics in asthmatic children. Neutrophil-predominant asthma is the most severe asthma phenotype with poor corticosteroid response. Gene expression profile of different asthma phenotypes not only improve our knowledge of childhood asthma, but also can guide asthma precision medicine.
