Objective To find out the trends and associated factors of birth defects in Guangdong province,and to provide the scientific evidences for setting the preventive strategies.Methods Retrospective description and trending analysis were conducted to analyze the birth defects surveillance data from 1996 to 2004 in Guangdong province.Results The total incidence of birth defects in Guangdong province from 1996 to 2003 was 134.4/10 000(7301/543 062),and increased to 212.1/10 000(2129/100 394)in 2004.Significant different birth defects rate was found between different maternal age(P

Objective To explore the clinical significance of early biomarkers in neonatal asphyxia diagnosis with myocardial damage by detection of ischemia modified albumin in neonatal serum(IMA) and glycogen phosphorylase isoenzyme BB(GPBB) for screening sensitive markers with direct myocardial injury.Methods 166 neonates were selected in our hospital as the research object,in which 136 cases with myocardial injury dividend into the experimental group and 30 cases into the control group.The experimental group were divided into mild group and severe group according to the degree of asphyxia.All the children were tested for GPBB and IMA 1 h after admission.Results The levels of GPBB in neonatal asphyxia myocardial injury group and severe asphyxia group were significantly higher than those in the control group,the difference was statistically significant(P<0.05).The sensitivity of GPBB in diagnosis of asphyxia was higher than that of IMA,the difference was statistically significant(P<0.05).Conclusion The degree of asphyxia is closely related to serum IMA,GPBB level in neonatal asphyxia complicated with myocardial injury.The sensitivity and specificity of GPBB in diagnosis asphyxia is better than IMA in children complicated with myocardial damage.

Objective:To explore the clinical characteristics, chest imaging manifestations, RAPID score and therapeutic situation in patients with parapneumonic pleural effusion (PPE) caused by streptococcus anginosus group (SAG), in order to provide help for the early diagnosis and treatment in clinical practices. Methods:The clinical data of 39 patients with PPE caused by SAG from January 2015 to May 2020 in Affiliated Hospital of Jining Medical University and Jining First People′s Hospital were retrospectively analyzed. The patients were classified by RAPID score.Results:Among 39 cases, males was in 31 cases (79.5%), females in 8 cases (20.5%), and aged 46 to 89 (65.31±10.53) years old. Fever was in 27 cases (69.2%), chest pain in 19 cases (48.7%), and dyspnea in 18 cases (46.2%). The chest CT findings showed consolidation shadows was in 30 cases (76.9%), encapsulated pleural effusion in 21 cases (53.8%), ground glass shadow in 18 cases (46.2%), nodules in 12 cases (30.8%), atelectasis in 8 cases (20.5%), and pneumothorax in 5 cases (12.8%). The complexity PPE was in 23 cases (59.0%), and empyema in 16 cases (41.0%). The microbiological culture results showed that streptococcus constellatus was detected in 25 cases (64.1%), streptococcus anginosus in 13 cases (33.3%), and streptococcus intermadius in 1 case (2.6%). After comprehensive treatment, 36 cases (92.3%) were improved, 3 cases (7.7%) died. According to the RAPID score, low-risk was in 13 cases (33.3%), intermediate-risk in 16 cases (41.0%), and high-risk in 10 cases (25.7%). The RAPID score in patients with low-risk, intermediate-risk and high-risk was (1.85 ± 0.38), (3.43 ± 0.51) and (5.30 ± 0.67) scores, and there was statistical difference ( F = 124.88, P<0.05). the length of stay in patients with low-risk, intermediate-risk and high-risk of RAPID score was (16.84 ± 5.57), (16.56 ± 7.05) and (28.20 ± 17.97) d, and there was statistical difference ( F = 4.41, P<0.05); the length of stay in patients with high-risk was significantly longer than that in patients with low-risk and intermediate-risk, and there was statistical difference ( P<0.05), there was no statistical difference between intermediate-risk patients and low-risk patients ( P>0.05). Conclusions:SAG, as important pathogens for the PPE, tends to induce CPPE and even pyopneumothorax. Clinical manifestations and imaging are not specific, which should be payed attention in clinical work. The patients with high-risk of RAPID score have more serious condition and worse prognosis.
