Objective To evaluate the efficacy of the enzyme-linked immunosorbent assay(ELISA),polymerase chain reaction(PCR),and gold chromatographic strip assay(GICA)in diagnosing clonorchiasis through a meta-analysis of diagnostic tests.Methods Relevant databases,including CNKI,the Wan Fang Database,VIP,and PubMed,were searched according to inclusion and exclusion criteria.Literature quality was assessed using RevMan 5.4 and Stata 18,and funnel plots,forest plots,and SROC curves were generated.Results A total of 50 articles met the inclusion criteria.Deeks'funnel plot analysis indicated no significant publication bias among the three methods.The combined effect size analysis revealed that the sensitivity and specificity of ELISA for detecting clonorchiasis were 0.93(0.89-0.95)and 0.94(0.92-0.96),respectively,with an area under the SROC curve of 0.98.For PCR,the sensitivity and specificity were 0.93(0.84-0.97)and 0.92(0.80-0.97),respectively,yielding an area under the SROC curve of 0.97.The sensitivity and specificity of the GICA method for detecting clonorchiasis were 0.91(0.83-0.96)and 0.95(0.87-0.98),respectively,with an area under the SROC curve of 0.97.Conclusions In the diagnosis of clonorchiasis,ELISA,PCR and GICA have high diagnostic value,but their ranges differ from each other.

Patient 1,a 12-day-old female infant,presented with fever,cough,dyspnea,and elevated infection markers,requiring respiratory support.Metagenomic next-generation sequencing(mNGS)of blood and bronchoalveolar lavage fluid revealed Legionella pneumophila(LP),leading to diagnoses of LP pneumonia and LP sepsis.The patient was treated with erythromycin for 15 days and azithromycin for 5 days,resulting in recovery and discharge.Patient 2,an 11-day-old female infant,presented with dyspnea,fever,elevated infection markers,and multiple organ dysfunction,requiring mechanical ventilation.mNGS of blood and cerebrospinal fluid indicated LP,leading to diagnoses of LP pneumonia,LP sepsis,and LP intracranial infection.The patient was treated with erythromycin for 19 days and was discharged after recovery.Neonatal LP pneumonia lacks specific clinical symptoms,and azithromycin is the preferred antimicrobial agent.The use of mNGS can provide early and definitive diagnosis for severe neonatal pneumonia of unknown origin.

OBJECTIVE: To evaluate the long-term prognosis of patients with ST-segment elevation myocardial infarction (STEMI) treated with different reperfusion strategies in Chinese county-level hospitals. METHODS: A total of 2,514 patients with STEMI from 32 hospitals participated in the China Acute Myocardial Infarction registry between January 2013 and September 2014. The success of fibrinolysis was assessed according to indirect measures of vascular recanalization. The primary outcome was 2-year mortality. RESULTS: Reperfusion therapy was used in 1,080 patients (42.9%): fibrinolysis ( n= 664, 61.5%) and primary percutaneous coronary intervention (PCI) ( n= 416, 38.5%). The most common reason for missing reperfusion therapy was a prehospital delay > 12 h (43%). Fibrinolysis [14.5%, hazard ratio ( HR): 0.59, 95% confidence interval ( CI) 0.44-0.80] and primary PCI (6.8%, HR= 0.32, 95% CI: 0.22-0.48) were associated with lower 2-year mortality than those with no reperfusion (28.5%). Among fibrinolysis-treated patients, 510 (76.8%) achieved successful clinical reperfusion; only 17.0% of those with failed fibrinolysis underwent rescue PCI. There was no difference in 2-year mortality between successful fibrinolysis and primary PCI (8.8% vs. 6.8%, HR = 1.53, 95% CI: 0.85-2.73). Failed fibrinolysis predicted a similar mortality (33.1%) to no reperfusion (33.1% vs. 28.5%, HR= 1.30, 95% CI: 0.93-1.81). CONCLUSION In Chinese county-level hospitals, only approximately 2/5 of patients with STEMI underwent reperfusion therapy, largely due to prehospital delay. Approximately 30% of patients with failed fibrinolysis and no reperfusion therapy did not survive at 2 years. Quality improvement initiativesare warranted, especially in public health education and fast referral for mechanical revascularization in cases of failed fibrinolysis.

Objective To analyze the correlation between uric acid and coronary atherosclerotic heart disease in adults. Methods A total of 186 patients with hyperuricemia from January 2020 to October 2021 were selected as the observation group and 186 subjects with normal blood uric acid were selected as the control group . The levels of uric acid, hs-CRP, MCP-1, IL-6, RANTES and adropin protein were measured . The SYNTAX score was used to assess the risk of coronary heart disease and the incidence rate of coronary heart disease was recorded. The correlation between uric acid and inflammatory indexes was analyzed by linear regression model . The relationship between serum uric acid level and coronary atherosclerotic heart was tested by spearman correlation test. Results The levels of hs-CRP, MCP-1, IL-6, RANTES and adropin protein in the observation group were higher than the control group significantly (P<0.05) . The syntax score of the observation group was higher than the control group significantly (P<0.05) .The incidence rate of coronary heart disease in the observation group was significantly higher than that in the control group, and the difference was statistically significant (P<0.05). The level of uric acid was significantly positively correlated with hs-CRP, MCP-1, IL-6, RANTES and adropin . There was positive correlation between serum uric acid and syntax score and the incidence of coronary atherosclerotic heart disease (P<0.05). Conclusion The increase of uric acid level can predict coronary atherosclerotic heart disease. Patients with hyperuricemia should actively carry out uric acid lowering treatment to prevent the risk of coronary atherosclerotic heart disease.

Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of breast myofibroblastoma. Methods: The clinicopathological data and prognostic information of 15 patients with breast myofibroblastoma diagnosed at the Department of Pathology of the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China from 2014 to 2022 were collected. Their clinical characteristics, histological subtypes, immunophenotypes and molecular characteristics were analyzed. Results: There were 12 female and 3 male patients, ranging in age from 18 to 78 years, with a median and average age of 52 years. There were 6 cases in the left breast and 9 cases in the right breast, including 12 cases in outer upper quadrant, 2 cases in inner upper quadrant and 1 case in outer lower quadrant. Most of the cases showed a well-defined nodule grossly, including pushing growth under the microscope in 13 cases, being completely separated from the surrounding breast tissue in 1 case, and infiltrating growth in 1 case. Among them, 12 cases were classic subtype and composed of occasional spindle cells with varying intervals of collagen fiber bundles; eight cases had a small amount of fat; one case had focal cartilage differentiation; one case was epithelioid subtype, in which epithelioid tumor cells were scattered in single filing or small clusters; one case was schwannoma-like subtype, and the tumor cells were arranged in a significant palisade shape, resembling schwannoma, and one case was invasive leiomyoma-like subtype, in which the tumor cells had eosinophilic cytoplasm and were arranged in bundles, and infiltrating into the surrounding mammary lobules like leiomyoma. Immunohistochemical studies showed that the tumor cells expressed desmin (14/15) and CD34 (14/15), as well as ER (15/15) and PR (15/15). Three cases with histologic subtypes of epithelioid subtype, schwannoma-like subtype and infiltrating leiomyoma-like subtype showed RB1 negative immunohistochemistry. Then FISH was performed to detect RB1/13q14 gene deletion, and identified RB1 gene deletion in all three cases. Fifteen cases were followed up for 2-100 months, and no recurrence was noted. Conclusions: Myofibroblastoma is a rare benign mesenchymal tumor of the breast. In addition to the classic type, there are many histological variants, among which the epithelioid subtype is easily confused with invasive lobular carcinoma. The schwannoma-like subtype is similar to schwannoma, while the invasive subtype is easily misdiagnosed as fibromatosis-like or spindle cell metaplastic carcinoma. Therefore, it is important to recognize the various histological subtypes and clinicopathological features of the tumor for making correct pathological diagnosis and rational clinical treatment.

Objective:To construct a cluster care of oral nutrition supplements (ONS) , and to explore its effect in home care of postoperative patients with gastric cancer.Methods:Literature search was conducted to review the status quo of ONS compliance at home in patients with gastric cancer after surgery, and analyze the existing problems. We summarized and formulated the cluster care plan according to the evidence, and established the home ONS management team and process. From November 2020 to October 2021, 107 patients with gastric cancer who needed to implement ONS at home in Gastrointestinal Surgery of Ningbo First Hospital were selected as research objects by convenience sampling. Postoperative patients with gastric cancer from November 2020 to April 2021 were set as the control group ( n=40) , and those from May to October 2021 were set as the observation group ( n=67) . The control group was treated with conventional ONS, and the observation group was treated with home ONS cluster care plan on the basis of the control group. The compliance of nutritional support, weight gain, body mass index increase and follow-up experience between the two groups were evaluated. Results:After six months of intervention, the scores of ONS compliance, weight gain, body mass index increase and follow-up experience in the observation group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The cluster care plan improves the ONS compliance at home, nutritional status and satisfaction with the follow-up by medical and nursing staff in patients with gastric cancer after surgery, which is worthy of clinical promotion.

Objective:To investigate the protective effect of intermittent fasting on radiation-induced cognitive impairment and the possible underlying mechanism.Methods:A total of 36 male 7-week old c57BL/6J mice were divided into Sham-irradiation and ad libitum (Sham-AL) group, irradiation and ad libitum (IR-AL) group, and irradiation add intermittent fasting (IR-IF) group according to the random number table method, with 12 mice in each group. The cognitive function of mice was assessed by novel object recognition task. The expressions of autophagy gene 5 (ATG5), microtubulesas sociated protein light chain II (LC3II), voltage dependent anion channel protein 1 (VDAC1), interleukin-1β (IL-1β), synaptophysin (SYP), synapsin I (SYN-1), and postsynaptic density 95 (PSD95) were tested by Western blot. The location of VDAC1 in mice hippocampus was detected by immunofluorescence.Results:The discrimination index (-22.45 ± 16.76) of IR-AL group was significantly ( t=3.032, P<0.05) lower than that of Sham-AL group (30.02 ± 9.05). Compared to Sham-AL group, IR-AL group had a decreased expressions of autophagy-related proteins (ATG5 and LC3II), mitochondrial marker (VDAC1), inflammatory factors (IL-1β) as well as synapse-associated proteins SYP, SYN-1 and PSD95 ( t=2.49, 2.19, 2.40, 3.47, 2.87, 2.25, 2.17, 2.31, P<0.05). Compared to IR-AL group, IR-IF group had an increased discrimination index (21.22 ± 5.62) and the increased expressions of ATG5, LC3II, VDAC1, IL-1β, SYP, SYN-1, and PSD95 ( t=2.70, 2.88, 2.71, 3.18, 3.18, 3.11, 3.30, 3.35, 2.53, P<0.05). The immunofluorescence assay revealed that VDAC1 was co-expressed with the markers of astrocytes (GFAP) and microglia (IBA-1), but not with neurons (NEUN). Conclusions:Intermittent fasting could greatly improve the cognitive function of irradiated mice possibly by upregulating VDAC1 expression, induce autophagy, and inhibit the release of inflammatory factors and protecting the synapticplasticity in the hippocampus.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
