ObjectiveTo measure fetal lung volumes in different gestational age (GA) by using 3D ultrasound,and further to obtain the regression formula between fetal lung volume and GA.MethodsTotal 228 fetal lung data had been collected.By using the 3D reconstruction function in Philips Qlab,fetal lung volumes were obtained by subtracting the non lung volumes from the whole thoracic volumes.For each slice of 3D data,thoracic area and non-lung area were manually outlined.The contour stacking technique in Qlab was then used to transform 2D slices into 3D volumes.ResultsThe measurement results of total 228 cases indicate that the fetal lung volumes increase with the GA.The average lung volume at GA of 20 weeks was 8.85 cm3,and 70.5 cm3 at 36 weeks.The fetal lung volume increases about 3- 4 cm3 in each week,and the increasing trend turns to a little lower after 24 weeks.During 33 to 34 week there was a great increasing in fetal volumes.Second-order regression,exponential regression and logarithmic regression were respectively used to characterize the relationship between fetal lung volume and GA.The second-order regression formula was:Volume =39.52 - 4.48 × GA + 0.149 × GA2.The exponential regression formula was:Ln (Volume) =- 8.233 + 1.747 × Ln(GA2 ).The logarithmic regression formula was:Ln(Volume) =- 2.413 + 0.29× GA- 0.003 × GA2.The correlation coefficients of three formulas are equal,with r =0.99,P ＜ 0.001.Conclusions 3D ultrasound fetal lung volume measurement is useful for fetal lung maturity assessment and thus can provide important referential information for prenatal diagnosis.

Objective To explore the effects of PBL teaching method on classroom atmosphere of basic nursing course.Methods Two classes of nursing sophomore were enrolled and were divided two groups,60 as PBL group and other 60 as traditional group.Students in two groups were evaluated by questionnaire of classroom atmosphere.Data were statistically analyzed through t-test,P＜0.05 standing for statistical significances.Results There were statistical differences in classroom atmosphere between two groups (P ＜ 0.05) ; class democracy,elicitation in teaching and student cooperation in PBL group were significantly better than those of traditional mode (P ＜ 0.05).There was no significant difference in learning autonomy between the two groups (P ＞0.05).Conclusions PBL teaching is conductive to stimulating students' learning potentials,culturing their cooperative learning,raising the efficiency of classroom learning and improving the classroom atmosphere.But learning autonomy of students needs to be further improved.

OBJECTIVETo discuss the effect of integrated traditional Chinese and Western medicine on Th1/Th2 cytokines level in children with asthma.

METHODChildren with asthma were randomly divided into control group and treatment group. The control group was given Montelukast Sodium tablets for 4 mg (2-5 years old) or 5 mg (6-14 years old), once every night before sleeping. At the same time, the treatment group was given Pingchuan water decoction additionally for one tie per day, in four to six-divided doses for eight weeks. On the other hand, groups of health children were selected as blank control. Before and after treatment, the level of IL-4, IL-13 and IFN-gamma were detected by elisa from 3 mL of venous blood.

RESULTBefore treatment, IL-4 and IL-13 in two groups were obviously higher than healthy group, but IFN-gamma was lower (P < 0.01, P < 0.05). After eight weeks, IL-4 and IL-13 in treatment group went down, but IFN-gamma increased. And there were significant different compared with the control group (P < 0.05).

CONCLUSIONTreating children asthma by integrated traditional Chinese and western medicine can obviously reduce IL4 and IL-13, increase IFN-gamma, and therefore lighten the airway inflammation, prevent asthma attacks effectively.

Objective To investigate the changes of mestruation patterns and adverse effects during the treatment of levonorgestrel-releasing intrauterine system (LNG-IUS) for symptomatic adenomyosis in a prospective cohort study. Methods From December, 2006 to December, 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in Peking Union Medical College Hospital were given LNG-IUS. Before and after placement of IUS, all patients′ parameters were recorded, including carrying status of IUS, symptoms and scores of dysmenorrhea, menstruation scores, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Risk factors for changes of menstruation patterns and adverse effects, and their impact on treatment effects were analyzed. Results Totally 1 100 cases met inclusion criteria, with median age 36 years (range 20-44 years), median follow-up 35 months (range 1-108 months). During follow-up changes of menstruation patterns increased significantly with amenorrhea and shortened-menstruation being the most common manifestations. On 3, 6, 12, 24, 36, 48 and 60 months after the placement of LNG-IUS, 0, 5.8%(43/744), 6.9%(47/682), 10.1%(60/595), 17.3%(87/502), 27.2%(104/383) and 29.6%(82/277) patients achieved amenorrhea respectively (P<0.01). Total and subclassification of adverse effects decreased significantly (P<0.01). Within 12 months and >12 months after placement, abdominal pain and body weight increasing ≥5 kg/year were the most common adverse effects. Changes of menstruation patterns, total and subclassifications of adverse effects were neither dependent on patient parameters, treatment modes and treatment effects, nor could predict future LNG-IUS carrying status (all P>0.05). After taking out of LNG-IUS, most changes of menstruation and adverse effects disappeared. Conclusions During the treatment of LNG-IUS for symptomatic adenomyosis, changes of menstruation patterns increase gradually with amenorrhea and shortened-menstruation being the most common manifestations, while adverse effects decrease significantly. Changes of menstruation patterns or adverse effects neither have any risk factor nor have impact on treatment effects.

Objective To investigate treatment effects of levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis with menorrhea in a prospective study. Methods From December 2006 to December 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in outpatient or inpatient clinics of Peking Union Medical College Hospital were given the treatment of LNG-IUS. Before and after placement of LNG-IUS, all the patients′parameters were recorded prospectively, including scores of menstruation blood loss, carrying status of IUS, symptoms and scores of dysmenorrhea, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Changes of pictorial chart scores of menstruation and distribution of anemia during follow-up were analyzed. Results Totally 1 100 women meets inclusion criteria, among which 618 cases (56.18%, 618/1 100) had severe menorrhea, with median follow-up period of 28 months (range 1-60 months), and accumulative carrying rate of 66% at 60 months follow-up. After placement of LNG-IUS, compared with baselines, pictorial chart scores and ratio of menorrhea had decreased significantly (all P<0.01), the scroes of menstruation were 157±34, 94±35, 70±33,67 ± 18, 67 ± 20, 65 ± 19, 66 ± 19, 65 ± 21 at 0, 3, 6, 12, 24, 36, 48 and 60 months respectively. During 24 months after placement of LNG-IUS, pictorial chart scores and distribution of anemia had improved significantly compared with preceding period (all P<0.01). We found no dependent factors predicting improvement of pictorial chart scores of menorrhea, which was neither relevant with simultaneous changes of menstruation patterns nor adverse effects (all P>0.05). Conclusions LNG-IUS is effective for adenomyosis of menorrhea. Improvement of menstruation blood loss is independent on patients characters, menstruation patterns or adverse effects.
