Clinical characteristics and risk factors of acute myocardial infarction in elderly patients with hyperuricemia in Suzhou / 公共卫生与预防医学

Objective To analyze the clinical characteristics and risk factors of ( acute myocardial infarction , AMI ) in elderly patients with ( hyperuricemia , HUA) in Suzhou, and to provide a theoretical basis for the prevention and treatment of AMI in patients with HUA. Methods Among of 356 patients with hyperuricemia aged ≥60 years who were admitted to Suzhou Jiulong Hospital from January 2016 to December 2021 were selected. The patients were divided into control group and AMI group according to whether they were complicated with AMI. The clinical data of the patients were collected from the medical record system, and the types of AMI and the lesions of the three main coronary vessels in patients with HUA were statistically analyzed. The serum BNP level and LVEF value of the two groups were compared. Univariate analysis and logistic regression analysis were conducted to analyze the risk factors of AMI in patients with HUA. Results Fifty-five cases (15.45%) of 356 patients with HUA developed AMI, including 31 males and 24 females. There were 26 patients (47.27%) with NSTEMI and 29 patients (52.73%) with STEMI. In addition, 30 cases (54.55%) had three-vessel lesions. Compared with the control group, the male ratio, average age, smoking history ratio, systolic blood pressure, FPG, LDL-C and Hcy levels in the AMI group were significantly increased (P<0.05), while LVEF values decreased (P<0.05). Smoking history (OR=2.987), high LDL-C (OR=3.439), high Hcy (OR=2.672) and high FPG (OR=3.874) were risk factors for AMI in patients with HUA (P<0.05). Conclusion HUA patients in Suzhou area have a high risk of AMI, and most of them are STEMI patients, with the characteristics of multi vessel branch lesions. For HUA patients with smoking history, poor control of Hcy, LDL-C and FPG, the risk of AMI is higher. Smoking cessation and control of LDL-C, Hcy and FPG levels should be actively adopted to reduce the risk of AMI.

Medical nutrition management and follow-up of patients with late-onset ornithine transcarbamylase deficiency / 中华实用儿科临床杂志

Objective:To explore the clinical characteristics and medical nutritional therapy of 6 patients with late-onset ornithine transcarbamylase (OTC) deficiency.Methods:The clinical features, biochemical data, gene variations and treatment outcomes of 6 children with late-onset OTC deficiency admitted to the Department of Clinical Nutrition, Children′s Hospital of Nanjing Medical University from January 2020 to April 2022 were retrospectively analyzed.The 6 patients were all intervened by a long-term medical nutrition management.Results:Liver dysfunction and hyperammonemia (172.1-348.0 μmol/L) were found in all the 6 children with late-onset OTC deficiency.Serum citrulline decreased in 3 patients (3.95-5.43 μmol/L). Three patients showed increased urine orotic acid (123.48-342.60 mmol/mol Cr). Urine uracil increased in 4 patients (106.77-1 207.26 mmol/mol Cr). Variations of the OTC gene [c.364G>C p. (E122Q), c.1028C>G p. (T343R), c.664-2(IVS6)A>C, c.635G>T p. (G212V), c.929_c.931delAAG p. (E310del), c.829C>T p. (R277W)] were identified in all patients.The 6 children were all managed by individualized medical nutrition program and followed up for a long time.During the follow-up period, 3 cases developed hypoproteinemia, acute metabolic crisis and growth retardation, 3 cases had normal growth and laboratory indicators, and 1 case received liver transplantation after 3 months of nutritional management. Conclusions:The clinical manifestations of OTC deficiency are non-specific.Blood amino acids, urine organic acids and genetic tests are important for the diagnosis.Long-term regular medical nutrition management is helpful to improve the prognosis and quality of life of children.

Diagnosis and treatment of neonatal necrotizing enterocolitis / 临床外科杂志

Necrotizing enterocolitis(NEC) is recognized as a process of inflammation and necrosis of the bowel wall in newborn.It can be early diagnosed and reasonably treated basing on the history and signs combined with imageological examination.For those who have surgical indications,operation should be intervened timely.Appropriate surgical strategy should be made according to the scope of intestinal necrosis to improve survival rate and prognosis.

New progress in the diagnosis of biliary atresia / 中华实用儿科临床杂志

Biliary atresia(BA)is an inflammatory cholangiopathy of infancy with progressive biliary prolifera-tion resulting in fibrosis and obstruction of extrahepatic and intrahepatic bile ducts,which mostly occurs in neonatal period. It is widely believed that the early diagnosis and timely surgical intervention(Kasai procedure within 60 days postpartum)of biliary atresia can lead to better prognosis for BA otherwise the poor prognosis would be caused,there-fore the biggest challenge is to make an accurate diagnosis at the early stage after birth. Recently some progresses have been achieved in the diagnosis of BA such as stool color card screening and serum bilirubin measurements. If the screen result is abnormal or manifestations appear,further physical and chemical examinations are required. Ultrasonography is considered as a non - invasive,cost - efficient,easy - operated primary method to diagnose or exclude BA. Other choices are magnetic resonance cholangiopancreatography,endoscopic retrograde cholangiopancreatography,duodenal tube test and dynamic examination of duodenal fluid and radionuclide hepatobiliary scanning. Intra - operative cholan-giogram and liver biopsy remain the gold standards for diagnosing biliary atresia. Although some biomarkers and exami-nations have been proved distinct and potential for diagnosis of biliary atresia,an individual and ideal method has not been acknowledged. To conclude,a well - coordinated multidisciplinary approach is required in the assessment of sus-pected cases of biliary atresia,multi - technique and method combination is the strategy and direction in early diagnosis of biliary atresia.

Screening and expression analysis of the specific tissue and serum microRNA profile in Hirschsprung disease / 中华实用儿科临床杂志

Objective To investigate the different expressions of pathological tissue and serum microRNAs (miRNAs)in Hirschsprung disease(HSCR). Methods Pathological colon tissues and serum samples were obtained from 52 confirmed HSCR cases respectively by surgery and pathology and from 52 matched controls,respectively. An initial screening of the tissues and serum microRNA expression were performed through TaqMan Low Density Array. The candidate tissue and serum miRNAs were validated by quantitative real - time - PCR in the 20 paired array samples and extra 32 paired samples after the integration of the screening result. The bioinformatical software online including miR-base,Target Scan,PicTar and MiRanda were used to predict the target mRNA of the consistent microRNAs in the tis-sues and the serum. Results Compared with the controls,47 microRNAs were differently expressed in HSCR tissues, including 17 up - regulated miRNAs and 30 down - regulated miRNAs;32 upregulated miRNAs were also detected to be differently expressed in the HSCR serum. Among these microRNAs,miR - 218 - 1 and miR - 885 - 5p were identi-fied to have a consistent significant different expression in both tissues and the serum,which were validated as high -expressed in microarray samples and expanded 32 paired samples(miR - 218 - 1:tissue array 0. 017 58 ± 0. 002 29 vs 0. 003 37 ± 0. 000 50,P ﹤ 0. 001;tissue expanded expression 0. 013 53 ± 0. 001 74 vs 0. 004 43 ± 0. 000 60,P ﹤0. 001. miR - 885 - 5p:tissue array 0. 000 30 ± 0. 000 11 vs 0. 000 04 ± 0. 0000 08,P = 0. 027 6;tissue expanded ex-pression 0. 004 59 ± 0. 000 16 vs 0. 000 04 ± 0. 000 01,P = 0. 014 5. miR - 218 - 1:serum array 0. 769 60 ± 0. 285 50 vs 0. 045 14 ± 0. 015 07,P = 0. 015 5;serum expanded expression 1. 151 00 ± 0. 430 00 vs 0. 023 07 ± 0. 003 81,P =0. 008 7. miR -885 -5p:serum array 1. 595 00 ±0. 441 70 vs 0. 169 40 ±0. 034 46,P =0. 001 2;serum expanded expres-sion 1. 689 00 ±0. 453 00 vs 0. 146 10 ± 0. 031 24,P = 0. 001 2). Specifically,the target genes of these 2 microRNAs were RET,PLAG1 and NeuroD1,which had been reported to be directly related to HSCR. Conclusions Significantly dif-ferential expressed miRNAs exist in the pathological tissue and the serum of HSCR. MiR - 218 - 1 and miR - 885 - 5p, which showing consistent differential expression,may be involved in the pathogenesis of HSCR.

Application of stroke volume variation in directing management of elderly septic shock patients / 天津医药

Objective To investigate the application of stroke volume variation (SVV) in directing management of elderly septic shock patients. Methods Patients who were diagnosed with elderly septic shock and supported with mechanical ventilation were in?cluded (n=28). They were divided into control group (n=13) and SVV group (n=15). Volume recovery was directed by CVP (central ve?nous pressure ) in control group and by SVV and CO (cardiac output) in SVV guoup respectively. Blood lactate, oxidation index, CVP , MVP, NT-proBNP, time of recovery, the length relying on mechanical ventilation and Vigileo parameters were compared after volume resuscition. During the period of treatment, the incidence of acute left ventricle dysfunction within 24 hours, MODS within 28 days and mortality rates of all causes were compared between these two groups. Changes in SVV, cardiac output (CO) and systemic vascular re?sistance (SVR) in SVV group before and after resustation were recorded. Results Blood lactate acid and NT-proBNP were significant?ly lower in SVV group compared with those in control group whereas oxidation index in SVV group were significantly higher than that of control group. The time of resuscitation and the duration relying on mechanical ventilation were shorter in SVV group than those in control group. On the contrary, the incidence of acute left ventricle dysfunction,MODS and all mortality rates were not significantly different between these two groups. There were significant differences between hemodynamic variables such as SVV, CO in SVV group before and after resuscitation. Conclusion SVV may direct volume resuscitation more effective in elderly septic shock than CVP does.

Value of ultrasonic diagnosis and analysis of missed diagnosis and misdiagnosis for neonatal annular pancreas / 中华超声影像学杂志

Objective To investigate the clinical value of ultrasonic diagnosis for neonatal annular pancreas,analyze the reasons of missed diagnosis and misdiagnosis,and improve diagnostic accuracy of ultrasonography for this disease.Methods Clinical data of 98 newborns with annular pancreas confirmed by gastrointestinal contrast and surgery were analyzed retrospectively.Preoperative ultrasonogram were compared with the result of gastrointestinal contrast and surgery.Ultrasound images failed to be correctly dignosed were further studied to summarize diagnostic points for this disease.Results Among the 98 cases, 75 were correctly diagnosed by ultrasound with a diagnostic accordance rate of 76.5%,1 8 were missed diagnosed and 5 were misdiagnosed with a total misdiagnosis rate of 23.5%.Ten cases associated with other congenital gastrointestinal tract anomalies were missed diagnosed due to ignoring scanning pancreas.Five cases were missed diagnosed due to obvious intestinal cavity flatulence.Three cases were missed diagnosed due to lack of awareness of the disease.Five cases were misdiagnosed for duodenal stenosis or duodenal atresia.Conclusions Ultrasound has important diagnostic value for neonatal annular pancreas,providing the dignostic evidences for clinical treatment.Thus it can be used as the preferred auxiliary examination of the disease.Since annular pancreas is often accompanied by other gastrointestinal malformations and can be interfered by abdominal gas,missed diagnosis and misdiagnosis occurred easily.To improve the accuracy of ultrasonic diagnosis,all causes of neonatal gastrointestinal tract obstructions should be considered during the examination.
