ABSTRACT

Objective:To characterize the mortality rate of residents in Minhang District of Shanghai from January to April in 2016-2020, and to determine the change in the epidemic Coronavirus Disease 2019 (COVID-19) in 2020. Methods:Data of mortality surveillance was collected from the death registry of Shanghai residents. Cause of death was coded and classified per the International Classification of Diseases (ICD-10). The standardized mortality rate was calculated based on the standard population of China in 1990. The analysis was performed by Excel 2016 and SPSS 20.0. Results:From 2016 to 2020, the average crude mortality rate of residents was 281.75/100 000 from January to April in Minhang District of Shanghai, and the standardized mortality rate was 66.57/100 000. The top five causes of death in the latest five years were cardiovascular diseases, tumor, respiratory diseases, endocrine diseases, and injury and poisoning. The mortality rate was the lowest from January to April in 2020 in the past five years; furthermore, the mortality rate of respiratory system diseases has decreased significantly. Conclusion:Sex, age, place and causes of death in residents are consistent from January to April across years in Minhang District of Shanghai. However, there are minor differences in 2020, which may be attributable to the epidemic of COVID-19.

ABSTRACT

OBJECTIVE@#To study the effect of astragaloside IV (AS-IV) on NOD-like receptor protein 3 (NLRP3) inflammasome in neonatal rats with hypoxic-ischemic brain damage (HIBD).@*METHODS@#A total of 24 Sprague-Dawley rats, aged 7 days, were randomly divided into a sham-operation group, an HIBD group, and an AS-IV treatment group, with 8 rats in each group. After 24 hours of modeling, brain tissue was collected for hematoxylin-eosin staining, yo-PRO-1 staining, and EthD-2 immunofluorescent staining in order to observe the cerebral protection effect of AS-IV in vivo. HT22 cells were used to prepare a model of oxygen-glycogen deprivation (OGD), and a concentration gradient (50-400 μmol/L) was established for AS-IV. CCK-8 assay was used to measure the viability of HT22 cells. RT-PCR and Western blot were used to observe the effect of different concentrations of AS-IV on the mRNA and protein expression of NLRP3, gasdermin D (GSDMD), caspase-1, and interleukin-1β (IL-1β).@*RESULTS@#Yo-Pro-1 and EthD-2 staining showed that compared with the sham-operation group, the HIBD group had an increase in pyroptotic cells with a small number of necrotic cells, and the AS-IV group had reductions in both pyroptotic and necrotic cells. Compared with the sham-operation group, the HIBD group had significantly higher protein expression levels of NLRP3, IL-1β, caspase-1, and GSDMD (@*CONCLUSIONS@#AS-IV may alleviate HIBD in neonatal rats by inhibiting the expression of NLRP3, GSDMD, caspase-1, and IL-1β.

ABSTRACT

The arachidonic acid (AA) metabolic pathway participates in various physiological processes as well as in the development of malignancies. We analyzed genomic alterations in AA metabolic enzymes in the Cancer Genome Atlas (TCGA) prostate cancer (PCa) dataset and found that the gene encoding soluble epoxide hydrolase (EPHX2) is frequently deleted in PCa. EPHX2 mRNA and protein expression in PCa was examined in multiple datasets by differential gene expression analysis and in a tissue microarray by immunohistochemistry. The expression data were analyzed in conjunction with clinicopathological variables. Both the mRNA and protein expression levels of EPHX2 were significantly decreased in tumors compared with normal prostate tissues and were inversely correlated with the Gleason grade and disease-free survival time. Furthermore, EPHX2 mRNA expression was significantly decreased in metastatic and recurrent PCa compared with localized and primary PCa, respectively. In addition, EPHX2 protein expression correlated negatively with Ki67 expression. In conclusion, EPHX2 deregulation is significantly correlated with the clinical characteristics of PCa progression and may serve as a prognostic marker for PCa.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of non-invasive prenatal testing (NIPT) in the prenatal screening and its role in the system of prenatal diagnosis.@*METHODS@#A total of 22 649 singleton pregnant women who were registered and finally delivered or had induced labor at Beijing Obstetrics and Gynecology Hospital of Capital Medical University were enrolled. The routes of prenatal screening were analyzed to evaluate the efficacy of prenatal screening. Meanwhile, 9268 pregnant women who underwent invasive prenatal diagnosis procedure were enrolled. The indications and results of prenatal diagnosis were analyzed to evaluate the effectiveness of prenatal screening.@*RESULTS@#60.24% of singleton pregnant women have opted for Down syndrome screening, and their age was mainly under 35. The proportion of women opted for NIPT was 34.74%, and were mainly between 35 and 39. The overall diagnostic rate of trisomy 21, 18 and 13 trisomy for those with high risk by NIPT was 0.89%, which yielded a positive predictive value of 75.71%. For those with moderate risk by serum screening, 0.30% was predicted with a high risk by NIPT. Among women undergoing prenatal diagnosis, 63.04% and 21.22% had the indication of advanced age or high risk by serum screening, and the positive predictive values were 5.1% and 5.13%, respectively. By contrast, 2.30% of women undergoing prenatal diagnosis had a high risk by NIPT, which yielded a positive predictive value of 54.46%.@*CONCLUSION@#With the change of the age composition of pregnant women and increase in the complexity of pregnancy in China, to build a prenatal screening system based on NIPT will be helpful to improve the efficiency of the current system of prenatal screening and diagnosis.

ABSTRACT

Background@#Goslings in several Taiwanese farms experienced gosling feather loss disease (GFL) at 21–35 days and goose broke feather disease (GBF) at 42–60 days. The prevalence ranges from a few birds to 500 cases per field. It is estimated that about 12,000 geese have been infected, the morbidity is 70–80% and the mortality is 20–30%. @*Objectives@#This study aims to investigate the pathogens that cause GFL and GBF. Focus on the study of the correlation between goose circovirus (GoCV) and goose parvovirus (GPV) with the goose feather loss in southern Taiwan. Furthermore, a phylogenetic tree was established to align the differences between southern and northern Taiwan and compare with virus strains from China and Europe. @*Methods@#Samples were collected from animal hospitals. Molecular and microscopy diagnostics were used to examine 92 geese. Specific quantitative polymerase chain reaction (Q-PCR) assays are performed to evaluate GPV and GoCV viral loads and simultaneously evaluated the feather loss conditions in geese with the scoring method. @*Results@#High prevalence of GoCV and GPV infection in geese showing signs of GFL and GBF. Inclusion body was detected in the feather follicles and Lieberkühn crypt epithelial cells. The Q-PCR showed the high correlation between feather loss and viruses during 3rd– 5th week. However, the infection was not detected using the same test in 60 healthy geese. @*Conclusions@#Thus, GFL and GBF appear to be significantly closely related to GoCV and GPV. The geese feathers showed increasing recovery after being quarantined and disinfected.

ABSTRACT

Background@#Little is known about the sensate recovery of skin grafts over free non-neurotized muscle flaps. The aim of this study was to evaluate the sensitivity of free gracilis muscle flaps and meshed skin grafts without nerve coaptation. @*Methods@#Thirteen consecutive patients with a median age of 55 years (range, 21–70 years) who underwent lower extremity reconstruction between September 2014 and October 2016 were included. Complications, flap contour, skin perception, and sensate recovery were assessed. @*Results@#All flaps survived completely. In one patient, wound dehiscence and infection occurred 1 month after surgery. After a median follow-up of 14 months (range, 10–51 months), a satisfactory contour and skin perception were achieved. The Semmes-Weinstein (SW) monofilament test (154.8±22 g) and static two-point discrimination (2-PD) (12.6±0.7 mm) showed intermediate recovery compared to the surrounding site (41% and 76%, respectively). There was an intermediate correlation between flap size and sensate recovery (2-PD: r=0.27, P=0.36; SW test: r=0.45, P=0.12). Vibration sensation recovered to 60%, whereas thermal sensation remained poor (19% at 5°C and 25% at 25°C). @*Conclusions@#Finer sensation could be partially restored. However, thermal sensation remained poor.

ABSTRACT

Objective To explore the feasibility of biomarkers in static cold storage (SCS) perfusate of donor kidney from donation after cardiac death (DCD) for predicting delayed graft function (DGF) after renal transplantation. Methods Clinical data of 64 recipients and 47 donors undergoing DCD renal transplantation were retrospectively analyzed. All recipients were divided into the DGF group (n=7) and immediate graft function (IGF) group (n=57) according to the incidence of postoperative DGF in the recipients. The levels of neutrophil gelatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP), interleukin -18(IL-18) and kidney injury molecule-1 (KIM-1) in the SCS perfusate were statistically compared between two groups, and the correlation with DGF was analyzed. The predictive value of each biomarker in the occurrence of DGF in recipients after renal transplantation was analyzed. Results The incidence of DGF in the recipients undergoing DCD renal transplantation was 11% (7/64). The NGAL level in the donor kidney perfusate of the DGF group was significantly higher than that in the IGF group (P=0.009). The NGAL level in the donor kidney perfusate was positively correlated with the incidence of DGF in recipients after renal transplantation (r=0.430, P < 0.001). The receiver operating characteristic (ROC) curve analysis showed that the increased levels of NGAL and KIM-1 in the perfusate yielded certain predictive value for DGF in recipients after renal transplantation (both P < 0.05). The area under the curve (AUC) of combined detection of NGAL and KIM-1 for predicting DGF in recipients after renal transplantation was 0.932 [95% confidence interval (CI) 0.850-1.000]. The sensitivity was calculated as 1.000 and 0.754 for the specificity (P < 0.05). Conclusions The NGAL level in the SCS perfusate of DCD donor kidney is associated with the occurrence of DGF in recipients after renal transplantation. Combined detection of NGAL and KIM-1 levels in the perfusate may accurately predict the occurrence of DGF in recipients after renal transplantation.

ABSTRACT

We summarized the experiences of construction and management of vaccine safety surveillance systems in different countries and regions by using literature review, and then made the recommendations of strengthening vaccine surveillance system in China. In the study, we found that multiple existing national and regional vaccine surveillance systems, such as VAERS and EudraVigilance, can ensure vaccine safety through multi-sectoral surveillance, identification of adverse signals, and promotion of awareness of active reporting. However, the monitoring systems have some limitations, such as reporting bias and system decentralization. Therefore, China's vaccine monitoring system should establish an effective vaccine surveillance system, which achieves multi-sectoral, active, open to the public surveillance.

ABSTRACT

Objective:To investigate auricular lobule index difference in healthy young female of different height or weight, and to provide an additional reference for otoplasty of auricular lobule.Methods:Subjects were made up of 266 healthy young females of Henan residents. Their height, weight, physiognomic ear breadth, morphological ear breadth, physiognomic ear length, morphological ear length, auricular lobule length, auricular lobule breadth were measured and calculated. All the data were analyzed by SPSS 15.0 software.Results:We obtained the means, standard deviation of each items, and data were treated statistically. In the 266 subjects, average height was (162.9±4.1) cm, weight (55.3±6.5) kg, morphological ear breadth (4.9±0.6) cm, morphological ear length (2.9±0.3) cm, physiognomic ear breadth (6.2±0.4) cm, physiognomic ear length (3.3±0.3) cm, auricular lobule breadth (1.6±0.3) cm, auricular lobule length (1.8±0.2) cm, lobule physiognomic ear breadth index (25.6±4.9)%, lobule-physiognomic ear length index (53.69±7.69)%, and auricular lobule index (91.4±19.3)%. The differences among the indices mentioned above were of statistical significance ( P<0.05); the indices of subjects of different height were significantly different ( P<0.05); the indices of subjects of different weight were of no statistical difference. ( P>0.05). Conclusions:The subjects of different height or weight have no different morphological ear breadth, morphological ear length, physiognomic ear breadth, physiognomic ear length, auricular lobule length, lobule-physiognomic ear length index and auricular lobule index; hence, the indices are no related to body height and weight. However, the subjects of different height have different auricular lobule breadth and lobule-physiognomic ear breadth index.

ABSTRACT

Objective:To investigate the use of the reference intervals for blood cell counting and the reference of industry standard in China.Methods:Information from all laboratories was collected using online questionnaire in 18 reference intervals survey in blood cell counting in 2019. The information includes the source of the reference intervals, the verification of the reference intervals, and the upper and lower limits of the reference intervals, the method used, the instrument, the reagent and the calibrator. Microsoft Excel 2007 software was used to analyze the results of all laboratories. The median and 95% confidence interval were calculated. The distribution of the reference intervals for blood cell counting and their conformance to industry standards were analyzed.Results:2, 869 labs reported the data. The main sources were industry standards and National Guide to Clinical Laboratory Procedures. The proportion was 33.30%-35.02% and 28.55%-30.90% respectively. 49.44%-55.13% of laboratories validated the reference interval when citing industry standards. The reference interval grouping of most laboratories (89.37%-91.69%) cited in RBC, Hgb and Hct were consistent with the industry standards. We compared the upper and lower limits of the reference intervals with that given by the industry standards, when the lower limit of the reference intervals of mean corpuscular hemoglobin concentration, absolute neutrophils count, absolute basophils count, absolute monocyte count, and lymphocyte percentage were compared. The upper limit of reference intervals of neutrophils percentage as well as upper and lower limits of reference intervals of mean corpuscular volume, mean corpuscular hemoglobin, absolute eosinophil count, basophils percentage, and monocyte percentage were also compared. The median and mode were equal and consistent with industry standards. For other labs, the upper and lower limits of the reference intervals were not consistent with the reference intervals given by the industry standards.Conclusion:The use of reference intervals for blood cell counting was not the same, and the implementation of industry standards was not optimistic. A considerable number of laboratories had not verified the reference intervals, so it was necessary to promote the industry standards for reference intervals.

ABSTRACT

Cervical cancer poses a major threat to public health worldwide, early diagnosis of cervical cancer can improve the survival rate of patients. The detection rate of the existing cervical cancer screening methods is not very stable, and there is no reliable non-invasive index to predict the recurrence, metastasis and prognosis of cervical cancer. We searched literaruture for cervical cancer-related diagnostic and prognostic indicators and included 20 related literature, confirming that liquid biopsy is expected to replace and supplement the existing methods of screening and testing. Circulating nucleotides are an important part of liquid bioassays, including circulating cell-free DNA (cfDNA) and circulating cell-free RNA (cfRNA), among which cfRNA is a potentially rich source of tumor biomarkers, especially in the early diagnosis of cervical cancer. It has unique specificity and great potential value in the early diagnosis.

ABSTRACT

Objective:To evaluate the prevalence of human rhinovirus (HRV) infection in hospitalized children in Tianjin and investigate the clinical impact of HRV infections.Methods:From July 2017 to December 2019, 2 945 nasopharyngeal secretion specimens were screened for HRV using polymerase chain reaction (PCR). VP4/VP2 sequences of HRV were further characterized. The clinical characteristics of the HRV infection were analyzed. The detection results of HRV for different groups and different months were compared using SPSS 19.0.Results:HRV-positive specimens accounted for 8.15% (240/2 945), of which 74.78% (86/115) were diagnosed with pneumonia, 40.83%(98/240) had co-infections with other common pathogens. HRV infections could be detected throughout the year with peaks in spring (11.00%, 66/660) and autumn (9.29%, 81/872). The positive rate of HRV was 4.14%(29/700) in winter. By VP4/VP2 sequence analysis, HRV-A was the most frequently detected strain(50.00%, 78/156), followed by HRV-C (41.67%, 65/156).46.15% (30/65) of HRV-C infections occurred in October and November. There were several different HRV-A types and HRV-C types. The most commonly detected HRV-A types were A12(11.54%, 9/78), A49(6.41%, 5/78), A22, A101, and A66(5.13%, 4/78), etc. The most common HRV-C types were C2(20.00%, 13/65), C22(9.23%, 6/65), C26, C43, C54 and C53(4.62%,3/65). Patients with HRV-A infections are more likely to show fever symptoms than HRV-C (χ2=5.411, P<0.05). No significant difference in other symptoms were found between the two types. Conclusions:HRV was a commonly detected virus among infants and had a clear seasonal distribution. It′s also possible for the HRV patients to have co-infections with other pathogens.HRV showed high genetic diversity.

ABSTRACT

Objective:To analyze the epidemiological characteristics and molecular classification of Human adenovirus (HAdV) and Human bocavirus (HBoV) infection in hospitalized children with acute respiratory infection in Tianjin Children′s Hospital.Methods:A total of 1 171 nasopharyngeal aspirates were collected from children with acute respiratory infection in Tianjin Children′s Hospital from March 2019 to February 2020. The specific primers designed by gene sequence were amplified by polymerase chain reation (PCR), and the positive amplification products were determined by sequencing. The sequences of HAdV and HBoV were compared in GenBank, molecular typed and phylogenetic tree analyzed of HAdV by MEGA7.0.26. The positive rate of HAdV and HBoV in different age groups(<6 months, 6-11 months, 12-23 months, 24-35 months, 36-47 months, ≥48 months) and seasons were compared by SPSS20.0.Results:Thirty HAdV were detected in 1 171 specimens, with a positive rate of 2.56% (30/1 171) and 84 cases with HBoV, with a positive rate of 7.17% (84/1 171).The positive detection rates of HAdV and HBoV in different age groups were 1.02% (4/392)-6.61% (8/121) and 4.09% (7/171)-11.45% (26/227), respectively. There was a significant difference in the positive detection rate of HAdV and HBoV in each age group (χ2=12.862, P=0.025; χ2=14.178, P=0.015).Winter is the peak period of HAdV infection, with a positive rate of 5.54% (15/271). The peak of HBoV infection is autumn and winter with a positive rate of 12.00% (36/300) and 12.5% (34/271), respectively, higher than that of the other two seasons (χ2=43.753, P<0.05). There was a significant difference in different season groups (χ2=13.287, P=0.004; χ2=43.753, P<0.05). The sequences of 29 adenoviruses were HAdV-3, 7 serotypes of HAdV-B subgroup and HAdV-1, 2, 5 serotypes of HAdV-C subgroup. Conclusion:HAdV and HBoV play important roles in children′s respiratory tract infections, and are closely related to factors such as the season and the age of the child. They should attract clinical attention.

ABSTRACT

Diabetic retinopathy (DR) is one of the most common and serious diabetic complications, which is the main cause of vision loss in adults. The specific vascular and neuropathology mechanism of DR is not clear. It has been demonstrated that Inflammatory reaction might be take effects in the development and progression of DR. Monocyte chemoattractant protein-1 (MCP-1), as an important chemokine in the inflammatory response process, promotes chemotactic and activating factors, destroys the blood-retinal barrier, causes retinal vascular disease, and activates microglia, which is related to the severity of the disease. With further research on MCP-1, it is possible to use chemokines and their receptors as target cells to control or slow down the progression of DR by reducing or inhibiting the production of MCP-1 in diabetic patients in the early stages of the disease. This study can provide new ideas and new methods about preventing and treating DR.

ABSTRACT

Objective:To investigate the prevalence and clinical characteristics of Mycoplasma pneumoniae( Mp) genotypes and subtypes in children in Tianjin. Methods:Children with pneumonia admitted to Tianjin Children′s Hospital from December 2017 to December 2019 were selected as the research objects. Bronchoalveolar lavage fluid was collected by fiberoptic bronchoscopy. The positive samples were detected by real-time fluorescent quantitative PCR and Mp culture. PCR-restriction fragment length polymorphism(RFLP) and multiple variable number tandem repeats were used for genotyping. Detailed clinical and laboratory data were collected for all cases. Results:The results of RFLP showed that there were 138 cases (78.9%) of typeⅠand 37 cases (21.1%) of type Ⅱ; 37 cases of type M3-5-6-2, including six subtypes B, G, M, S, V and Y; 138 cases of M4-5-7-2 were detected, including seven subtypes of E, J, P, U, X, Z and a. In M3-5-6-2 type, there were 1 case of P1-Ⅰtype (2.7%), 36 cases of P1-Ⅱtype (97.3%), 137 cases of P1-Ⅰ type (99.2%) and 1 case of P1-Ⅱ type (0.7%) in M4-5-7-2 type. There was no significant difference in genotype distribution among different age groups. There were statistical differences in the distribution of four seasons among the 13 genotypes of B, G, M, S, V, Y and E, J, P, U, X, Z, a. All Mp infected children had symptoms of fever and cough. The hospitalization time, fever duration, high fever (>39℃), cough duration, skin changes, digestive system symptoms and liver function injury rate of P1-Ⅰ/M4-5-7-2 pneumonia children were higher than those of P1-Ⅱ/M3-5-6-2 pneumonia children, but the difference was not statistically significant. The WBC count of P1-Ⅱ/M3-5-6-2 types was higher than that of typeⅠand M4-5-7-2; the LDH of P1-Ⅰ/M4-5-7-2 was higher than that of Ⅱ and M3-5-6-2, with statistical difference. There was no significant difference in the incidence of inflammatory consolidation, atelectasis, pleural thickening and pleural effusion among different genotypes. Conclusions:Mp infection in children with pneumonia in Tianjin is mainly P1-Ⅰ/ M4-5-7-2, and P1-Ⅱ is on the rise. P1-Ⅰ and M4-5-7-2 were associated with fever and severe symptoms.

ABSTRACT

Objective:To investigate the molecular epidemiological characteristics of norovirus (NoV) in hospitalized children with sporadic acute gastroenteritis in Tianjin in 2019.Methods:Fecal specimens and clinical data were collected from 3 116 hospitalized children with sporadic acute gastroenteritis possibly caused by viral infection in Tianjin Children′ Hospital between January and December, 2019. Real-time quantitative PCR was used to detect NoV. Partial sequences of RNA-dependent RNA polymerase (RdRp) and capsid genes of NoV were amplified by RT-PCR. Sequence alignment and phylogenetic analysis were performed for further analysis.Results:Among the 3 116 specimens, 809 (26.0%) were positive for NoV. There were significant differences in NoV detection rate between different age groups ( P=0.000), and the highest NoV detection rate (31.6%) was observed in the age group of 7-12 months. Moreover, the detection rate of NoV varied with seasons ( P=0.000), and the NoV detection rate was highest in winter (39.0%). Based on the sequence analysis of RdRp and capsid genes, 286 identified NoV strains belonged to six genotypes, which were GⅡ.P12-GⅡ.3, GⅡ.P16-GⅡ.2, GⅡ.P17-GⅡ.17, GⅡ.Pe-GⅡ.2, GⅡ.Pe-GⅡ.3 and GⅡ.Pe-GⅡ.4. The predominant genotype was GⅡ.Pe-GⅡ.4 Sydney 2012 (61.2%), followed by GⅡ.P12-GⅡ.3 (33.6%, 96/286), GⅡ.Pe-GⅡ.3 (2.4%, 7/286), GⅡ.P16-GⅡ.2 (2.1%, 6/286), GⅡ.Pe-GⅡ.2 (0.3%, 1/286) and GⅡ.P17-GⅡ.17 (0.3%, 1/286). Patients carrying the NoV of GⅡ.Pe-GⅡ.4 Sydney 2012 genotype were likely to suffer from vomiting than those positive for NoV of GⅡ.P12-GⅡ.3 genotype. Conclusions:NoV was an important pathogen causing acute gastroenteritis in children. GⅡ.Pe-GⅡ.4 Sydney 2012 and GⅡ.P12-GⅡ.3 were the major genotypes of NoV in hospitalized children with sporadic acute gastroenteritis in Tianjin in 2019.

ABSTRACT

A survey on professional knowledge levels was conducted from April to October 2019 among 388 general practitioners (GPs) from 46 community health service centers and 30 township health centers of 6 provinces selected by stratified random sampling method. The overall knowledge test score was 31.82—84.09(56.94±9.19) points, and the pass rate was 36.3% (141/388). There were significant differences in test scores among participants with different types of work units, regions, provinces, marital status, educational background, professional titles, types of employment, length of service, and training status (all P<0.05). Multivariate regression analysis showed that educational background ( B=-2.835), professional title ( B=-8.867), and participation in professional course training ( B=2.214) were the influencing factors of knowledge level (all P<0.05). The pass rates in knowledge of prevention/health management (13.7%, 53/388) and policies and regulations (12.1%, 47/388) were low. The results show that the levels of professional knowledge among GPs working in grassroots health institutions are relatively low, and suggest that continuing education should be strengthened to improve the professional knowledge level of GPs in primary care institutions, particularly, knowledge of health policies and regulations, disease prevention and health management.
