ObjectivesTo summarize the application ofGuidelines for the Management of Community-Acquired Pneu-monia (CAP) (2013 edition) in the diagnosis and treatment of children with CAP.MethodsThe clinical features of 209 children with non-severe CAP at different age stages were retrospectively analyzed. The curative effect of azythromycin was summarized which was used as ifrst-line antibiotics in the CAP treatment.ResultsIn 209 CAP children, the onset of 94 children was occurred in spring and summer and 115 occurred in autumn and winter. The white blood cell counts (WBC) in 51 CAP children (24.4%) were more than 10.0×109/L and absolute neutrophil counts (ANC) in 91 CAP children (43.5%) were more than 5.0×109/L. C-reactive protein levels in 199 CAP children (95.7%) were increased and MP-IgM showed positive in 94 CAP children (45.0%). 173 CAP children (82.8%) presented unilateral inlfammatory lesions in chest X-ray, and the right side was predominant. There was no difference in onset season among different age groups (P>0.05). However, the percentage of WBC≥10×109/L among different age groups were signiifcantly different (P=0.002) and the percentage of WBC≥10×109/L was highest in infants and young children group. The proportion of onset in spring and summer was signiifcantly higher in MP-IgM positive group than that in MP-IgM negative group (P<0.01). The total effective rate of azithromycin used as ifrst-line antibiotics was 98.1% (205/209), and there was no signiifcant difference in total effective rate of azithromycin between MP and non-MP pneumonia groups.Con-clusionsThe Guidelines for the Management of CAP (2013 edition) have a reference value in the diagnosis and treatment of CAP in our region where the CAP in children has some different features.

Objective To evaluate the value of MSCT scores on surgery method selection and its difficulty estimation for hepatic cystic echinococcosis. Methods Based on the CT features of hepatic cystic echinococcosis ( HCE), an integral system including 7 items wasestablished. Images of preoperative CT examination performed on 71 cases of hepatic cystic echnococcosis were retrospectively analyzed by the integral system and compared with actual surgical. Total 93 cystic lesions were divided into 3 groups based on CT scores: Group A suitable for total cystectom (0 to 5 score), Group B suitable for subtotal cystectom (6 to 10 score), and Group C suitable forendocystectomy ( ≥11 scores, or4 score in one item). Spearman rank correlation was used to analyze the relationship between WHO classification of cystic echinococcosis and actual surgery methods, the relationship between operation mode forecasted by CT scores and actual surgery methods, the relationship between vessel scores of cyst and actual surgery methods, and that between biliary score of cyst and actual surgery methods. Fisher exact test and Chi-square test were used to evaluate the incidence of residual cavity in patients with different biliary scores. Results Thirty nine cysts got 0 to 5 scores, 45 cysts got 6 to 10 scores and 9 cysts got more than 10 scores. Total cystectom was performed on 30 cysts, subtotal cystectomy on 40 cysts and performed endocystectomy on 23 cysts, actually. Actual operation methods were correlated with that predicated by CT scores ( r = 0. 741, P ＜ 0. 01 ), and with vessels score and biliary score (r = 0. 587,0. 327 respectively,P ＜ 0. 01 ). The higher the biliary score, the higher the incidence of postoperative biliary tract complications. Conclusions Preoperative CT scoring was an easy and objective way to accurately predict the surgery methods and its difficulty for hepatic cystic cnechnococosis.

Objective:To investigate the influencing factors and to build a model for predicting successful labor induction with cervical ripening balloon (CRB) in primipara.Methods:312 cases of primipara in late trimester of pregnancy induced by CRB between January 2018 and April 2019 in the First Affiliated Hospital of Shenzhen University were reviewed retrospectively. Factors including gravidity, age, body height, body weight, body mass index (BMI), the cervical Bishop score, neonatal birth weight, pregnant complication and other factors were collected to analyze the effect on successful labor induction.Results:Pregnancy times, cervical Bishop score and height in primipara were positively correlated with the success rate of induced labor, while BMI and neonatal weight were negatively correlated with the success rate of induced labor. The area under receiver operating characteristic (ROC) curve was 0.849 and diagnostic threshold was 0.725, with a sensitivity of 80.7% and a specificity of 75.7%.Conclusions:Among the primipara, the gravidity and cervical Bishop score are the most significant factors influencing the successful labor induction. These factors can be used as the predictive indexes for the outcome of labor induction along with pregnancy times, height, BMI and neonatal birth weight, which is beneficial to reduce the artificial interventions and improve the success rate of labor induction.

Objective: To explore correlation among clinic blood pressure (CBP), ambulatory blood pressure (ABP) and cardiovascular diseases in diabetic populations.Methods: A total of 336 patients complicated with type 2 diabetes mellitus, who received 24h ambulatory blood pressure monitoring, were selected.According to complicated with coronary heart disease or stroke or not, they were divided into cardiovascular disease group (CVD group, n=122) and no cardiovascular disease group (NCVD group, n=214).Blood lipids, blood pressure, CBP and ABP etc.were compared between two groups;according to median of 24h mean SBP (122mmHg), they were divided into <122mmHg group (n=168) and ≥122mmHg group (n=168), incidence of cardiovascular diseases was compared between these two groups.Results: (1) Compared with NCVD group, there were significant rise in age, percentages of smoking and hypertension, and plasma hsCRP level in CVD group (P<0.05 or <0.01);for ambulatory blood pressure,there were significant rise in levels of 24h mean SBP(mSBP) [(119.8±8.7)mmHg vs.(124.4±9.6) mmHg], daytime SBP (dSBP)[(121.4±9.3) mmHg vs.(128.0±10.3) mmHg] and nighttime SBP(nSBP) [(114.4±4.2) mmHg vs.(120.8±4.7) mmHg] in CVD group, P<0.01 all;there was no significant difference in CBP between two groups;(2) compared with <122mmHg group, there were significant rise in percentages of stroke (20.2% vs.25.0%) and total cardiovascular diseases (32.7% vs.39.9%) in ≥122mmHg group, P<0.01 both;(3) Logistic regression analysis indicated that diabetic patients no matter complicated with hypertension or not, 24h mean SBP was always an independent risk factors of diabetic patients complicated cardiovascular diseases (OR=1.83, 1.36, P<0.05 all).Conclusion: ABP is superior to CBP in predicting cardiovascular risk in patients with diabetes, and 24h mean SBP may be a good ABP index to predict cardiovascular risk.
