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.

ObjectiveTo introduce the application of slender narrow subcutaneous fascia pedicle flap in repairing the cavity of conchs wound in microtia plasty,and to investigate its survival mechanism.MethodsThe all 6 congenital microtia cases were repaired with the concha compound flap up rotation.The all microtia concha wounds were repaired with the slender narrow pedicle.The lateral maxillocevicai fasciotaneous flap with its slender subcutaneous fascia pedlcle located in front of auricle.The size of the flaps ranged from 3.0 cm × 3.0 cm to 4.0 cm × 4.5 cm,The width and length of the pedicle ranged 1.0-1.5 cm and 3.5-4.5 cm.Results6 cases of the slender narrow subcutaneous fascia pedlcle flaps all survived,with primary wound healing and ideal appearance.ConclusionsThis slender narrow subcutaneous fascia pedlcle flap does not contain any major blood vessel,which is dissected easily in the operation.Due to its slender narrow pedicle,the flap rotation is also easy and its coverage area is large,without cat ears.The postoperative appearance (color,lexture,cosmetic aspect)is satisfactory.The slender narrow flap is an extraordinary new design and is ideal for the cavity of concha wound repair in the microtia plasty.

Objective To investigate the application and survival mechanism of a long and narrow pedicle flap which was used to repair the tissue defects after removal of tumor in aged patients.Methods The long and narrow pedicle flap was designed with its pedicle located beside wound surface along the pathway of well-known or perforating branch blood vessel to repair the defect caused by removing the tumor in aged patients.The size of the flaps ranged from 3 cm × 4 cm to 10 cm × 12 cm.The length and width of the pedicle ranged 2 - 8 cm and 1.0 - 1.5 cm.Results This flap was used in 17 cases.The flap was survived well in 14 patients,and healed later in other 3 patients because of wrong bandaging in earlier period.Conclusions The capability of bearing ischemia and hypoxia of the flap tissue is stronger after transfer owing to low metabolic rate in the skin tissue in aged patients.The flap is easily survived by repairing the tissue defects after removal of tumors in aged patients with the long and narrow pedicle flap.The pedicle of flap is narrow and long,and the transposition of the narrow pedicle flap is easy.The postoperative appearance is satisfactory.It is an ideal choice for repairing the defect caused by removal of tumor in aged patients.

Objective To analyze the MSCT imaging of vascular and biliary ducts affected by hepatic cystic enchionococcosis disease(HCD),and to evaluate the 3D image reconstruction of MSCT.Methods Forty four cases with HCD confirmed by radical surgery were collected in this study.All cases underwent multi-phase scanning with 64-slices CT,and 3D image reconstruction of hepatic vessels was performed.Three cases suspected of bile duct complications were examined with negative CT cholangiography.All the imaging data were acquired before surgery.The spatial relationships between the cysts and the neighbor vessels and(or)bile ducts were compared with the findings during operation,then consistency was tested.Results Altogether 46 lesions were detected by MSCT before surgery.All lesions were found and diagnosed correctly,including 3 lesions rupturing into biliary duct Compared with surgery findings,the spatial relationships between lesions and the vessels were entirely consistent in first grade portal vein(14 cases)and inferior macular vein(18 cases).The Kappa values were 0.8805,0.6087,0.7751,0.7392 for first grade hepatic artery,second grade hepatic artery,second grade portal vein and hepatic vein.The relationships between bile ducts and lesions also matched in 3 bile-duct fistula cases.Conclusions MSCT with its 3D technique showed a high accuracy in the assessment of spatial relationship between vessels,biliary duct and lesions.It provides comprehensive imaging information for surgery.

Objective To analyze the imaging findings of coronary angiography using 64-slice row CT and investigate the difference of coronary artery's morphological characteristics between Uygur and Han populations.Methods A retrospective study was made to coronary CT angiographic images of 88 Uygur cases matched with 88 Han cases.The data were analyzed with X~2 test and paired Wilcoxon test.Results The coronary CT angiographic findings were different between Uygur population and Han population in the following aspects: there were 62, 18, and 8 cases with the left coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 73, 14, and 8 cases in Han population respectively (t=8319, P<0.05).And there were 78,7, and 3 cases with the right coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 82, 1 and 1 case respectively in Han population (t=6936, P<0.05).The incidence of the sharp marginal branch were 52 (52.09%) and 67 (76.13%) in the two populations respectively (X~2=5.8381, P<0.05).The cases with various malformations of coronary arteries were 16 and 6 cases in the two populations respectively(X~2 =5.1948,P<0.05).The cases with LCA variations were 28 and 49 cases in the two populations respectively(t =2692,P<0.05) and the number with RCA variations were 33 and 27 cases in the two populations respectively(2 =968,P<0.05).Conclusions There are lots of differences of the coronary artery morphology between the Uygur and Han populations.Firstly, these differences may be related to different patterns in coronary angiography.Secondly, these differences may be related to differences between Uygur and Han populations in the incidence and severity of coronary heart disease.

Objective To observe the effect of recombinant human growth hormone on flap survival and angiogenesis through preoperative local subcutaneous continuous injection of rhGH in narrow pedicle flap.Methods 40 rats were divided into two groups at random,named as groups Ⅰ and Ⅱ,20 rats each.A narrow pedicle flap was designed on the left back of rat in groups Ⅰ and Ⅱ.Then group Ⅰ was subcutaneously injected with rhGH [0.4 IU/(kg · d)] for 3 days.Another group did not have any injection.After 3 days,we established a model of narrow pedicle flaps in the left back of animals.After operation,the flaps of groups Ⅰ and Ⅱ were injected with rhGH [0.4 IU/(kg · d)]for 7 days.The survival percentage of the flap was calculated at 7'th day.Specimens were collected at the diffent point of time.Expression of VEGF,CD34 was detected by immunohistochemistry and ELISA.The MVD of the flaps was also calculated.Results According to the 7 days' observation after the surgery,the percentage of flap survival area for groups Ⅰ and Ⅱ was (100.00±0.00)％,and (94.00±1.10)％ (P＜0.05).The expression of VEGF,CD34 and the MVD values of group Ⅰ was higher than that of group Ⅱ at the same point of time (P＜0.05),especially on the day of surgery.Conclusions Preoperative and local subcutaneaous continuous injection of rhGH on flaps can enhance the expression of VEGF and CD34 and microvascular formation,mitigate the damage of ischemia and hypoxia to flap during the postoperative period,and therefore improve the survival of narrow pedicle flap.

Objective To analyze the incidence of coronary myocardial bridge (MB) of the Uyghur and Han peoples with 64-slice CT. Methods A total of 1350 patients with suspected of coronary disease or other diseases underwent coronary angiography with 64-slice CT, among them 341 patients were diagnosed as MB, including 260 Han people, 70 Uyghur people, 7 Muslim people and 4 people of Kazak ethnic minority group. The incidence of MB of the Uyghur and Han people was calculated respectively; incidence of MB in proximal, middle and distal segment of left anterior descending (LAD), the first diagonal branch (D1), the second diagonal branch (D2), obtuse marginal (OM), left circumflex (LCX) and right coronary artery (RCA) between two races were compared with Chi-Square test. Results Totally 341 patients had 439 MB, 332 in Han people, 92 in Uyghur people, 9 in Muslim people and 6 in Kazak ethnic minority group with 64-slice CT. There was no statistical significance of MB incidence between the Uyghur and Han people in coronary artery (P＞0.05), including the proximal, middle and distal segment of LAD. Conclusion The 64-slice CT can effectively detect MB with a high special resolution. There is no statistical significance of MB incidence between the Uyghur and the Han people in each coronary artery.
