Objective To explore effects of ginsenosides Rg1 on the expression of poly(ADP-ribose) polymerase-1 (PARP-1) and tumor necrosis factor receptor (TNFR) 1 in cortex cells after focal cerebral ischemia in rats. Methods Ninety healthy rats were randomly divided into sham-operative group, focal cerebral ischemia group, ginsenoside Rg 1groups (low, medium and high concentrations) and drug control group. Rats were intraperitoneally injected saline 45 mg/kg, saline 45 mg/kg+ginsenosides Rg1 10, 20 and 40 mg/kg, nimodipine 1 mg/kg 5 d before surgery, respectively. Focal cerebral isch?emia model was made by middle cerebral artery occluding in rats. The neurological deficit score and TTC staining were used to verify the success of the rat model. The expressions of PARP-1 and TNFR1 were evaluated by immunohistochemical meth?od and Western blot technique. Results There were obvious symptoms of neurological deficit and large pale infarct area in focal cerebral ischemia group compared with those of sham-operative group. There were higher percentages of neurological deficit score and infarct area in ginsenosides Rg1 groups and positive control group than those of sham-operative group, but which were lower than those of ischemia group (P<0.05). There were no significant differences between ginsenosides Rg1 groups and positive control group. The positive cells of PARP-1 and TNFR1 were higher in ginsenosides Rg1 low-dose group than those of sham-operative group and positive control group, while ones of medium and high-dose Rg1 group were higher than those of sham-operative group, and were lower than those of ischemia group (P<0.05). Compared with sham-op?erative group, PARP-1 and TNFR1 expression strips were significantly enhanced in ischemia group. Expression strips were higher in ginsenosides Rg1 low-dose group than those of sham-operative group. Expression strips were higher in ginsen?osides Rg1 medium-dose group than those of sham-operative group, but which were lower than those of ischemia group, and ones of high-dose group were lower than ischemia group (P<0.05). Conclusion Ginsenoside Rg1 shows protective effects on focal ischemia injury, which may be related with down-regulation of the expression of PARP-1 and TNFR1.

Objective To investigate the correlation between auditory steady state responses(ASSR)and click audiotory brainstem respone(cABR)of infants as a function of different ages below 36 months.Methods 299 infants(497 ears from 1 to 36 months)were divided into 5 groups:208 ears in group 1(1~ month old),81 ears in group 2(4~ months old),47 ears in group 3(7~ months old),53 ears in group 4(13~ months old),and 108 ears in group 5(19~36 months old).The correlation analysis of the thresholds of 2 kHz and 4 kHz between ABR and ASSR were conducted,respectively with SPSS.Results In group 1,the correlation coefficient at 2 kHz between ABR and ASSR was 0.499,the correlation coefficient at 4 kHz between ABR and ASSR was 0.541,the correlation coefficient of the means of 2 kHz and 4 kHz between ABR and ASSR was 0.531.In group 2,these three correlation coefficients were 0.678,0.705 and 0.726,for group 3,0.792,0.717 and 0.777;for group 4,0.934,0.880 and 0.915,for group 5,0.817,0.810 and 0.867.Conclusion For infants of 1~18 months old,the correlation between ABR and ASSR increases as a function of ages.

Objective To share our experiences on integrated services in providing fetal diagnosis and postnatal treatment for congenital diaphragmatic hernia(CDH).Methods A retrospective analysis was conducted on 25 pregnancies diagnosed as CDH by both prenatal ultrasound and MRI in Maternal and Children Hospital of Guangdong Province from January 2012 to January 2014.All of the subjects received integral medical management including prenatal management (prenatal diagnosis and consultation), perinatal management (prenatal care and delivery) and neonatal treatment.Results Among the 25 CDH fetuses, 11 were mild, nine were moderate, and five were severe.One severe case, who was diagnosed at 26 gestational weeks, was aborted on demand of the mother.The other 24 cases continued their pregnancy and all delivered after 35 weeks including 13 cesarean sections (one due to twin pregnancy and 12 due to maternal demand) and 11 vaginal birth.The mean gestational age when CDH was diagnosed was (24.5 ± 3.5) weeks, and the 24 women delivered at an average of (37.5 ± 1.4) gestational weeks.The eleven mild cases accepted mask oxygenation.For those 13 moderate or severe CDH cases, all received dexamethasone to promote fetal lung maturity at 32 gestational weeks, seven were intubated before clamp the cord, and the other six did after.These 13 babies accepted high-frequency oscillation ventilation, with a median duration of 58 hours, and some of them treated with inhaled nitric oxide on requirement with a median duration of 52 hours.Except two cases died before operation, the rest 22 cases underwent neonatal surgery.One moderate case died at 48 hours after surgery due to pulmonary hypertension and respiratory failure.Another one severe case withdrew treatment at two months old.The other 20 infants recovered fully.Conclusions Integrated management including prenatal diagnosis and postnatal treatment, provides an effective and streamlined mode for diagnosis and treatment of CDH.Therefore,it might minimize potential medical risks.

Objective To discuss the diagnosis and early intervention treatment of fetal congenital broncho-genic cysts based on the cases reviewed. Methods The clinical features of 7 infants presenting bronchogenic cysts diagnosed antenatally from January 2013 to May 2014 in Guangdong Women and Children's Hospital and Health In-stitute were reviewed retrospectively. Pathology,the prenatal diagnosis and treatment of bronchogenic cysts experience were summarized combined with CT after birth and surgery. Results Based on the prenatal diagnosis of fetal and postnatal CT and surgical pathology,a total of 7 cases with congenital bronchial cysts were diagnosed. Of which 4 ca-ses were suggestive of congenital cystsic adenomatoid malformation by prenatal diagnosis,and the other 3 cases had fetal bronchial cysts by prenatal diagnosis,antenatal diagnosis was accurate in 42. 9%(3 / 7 cases). CT examinations were taken in 7 cases after birth,and the cyst excision was performed on them with surgery thoracic approach;the average age at surgery was(5. 3 ± 1. 7)months. Four cases had simple bronchial cystss,2 cases with congenital cystsic adenomatoid malformation,1 case with congenital pulmonary sequestration. The accuracy of CT diagnosis was 85. 7%(6 / 7 cases). All surgical treatment was effective. Conclusions Fetal bronchial cysts is always associated with the other presence of lung congenital malformations. Prenatal diagnosis of congenital bronchial cysts is difficult. Prenatal diagnosis is difficult to exclude congenital cystsic adenomatoid malformation. To avoid symptoms like oppres-sion,infection,prenatal diagnosis combined with CT examination after birth and early treatment are necessary and reliable clinically.

OBJECTIVE: To observe and analyze the function and morphology of pharyngeal ostium of the eustachian tubes in secretory otitis media and chronic rhinosinusitis in children under direct vision,in order to provide an objective basis for clinical treatments. METHOD: Fifty cases of secretory otitis media,50 cases of chronic rhinosinusitis and a control group of 50 cases with hoarseness were examined under video laryngoscope to observe the pharyngeal ostium morphological changes of the eustachian tubes, and their functional statuses were tested by using acoustic impedance instrument. All the data were analyzed by statistical methods. RESULT: (1) In the secretory otitis group, the abnomal rate of the pharyngeal ostium of the eustachian tubes was 94% while the chronic rhinosinusitis group was 80%,and between them there was no significant differences (P > 0.05). But both of them had significant differences with the control group (P < 0.05). (2) In the secretory otitis group, the rate of the eustachian tube dysfunction was 70% while the chronic rhinosinusitis group was 26%, and between them there was significant differences (P < 0.05), and both of them have significant differences when compared with the control group (P < 0.05). CONCLUSION There are some abnormal points exist in the function and the morphology of the eustachian tube in secretory otitis media and chronic rhinosinusitis in children. Eustachian tube dysfunction played a dominant role in the pathogenesis of secretory otitis media in children rather than the morphological change did compared to the chronic rhinosinusitis in children.

0bjective To investigate the relationships between the peripheral lung cancer and pulmonary vessels or bronchi by 16-row muhislice computed tomography(MSCT)and analyze the related factors.Methods Fifty-four patients with peripheral lung cancer confirmed pathologically underwent contrast-erdaanced MSC TI Multiplanar reformation(MPR)and maximum intensity projection(MIP)in all patients were used to demonstrate the relationships between the peripheral lung cancer and pulmonary vessels,bronchi.The relationships were categorized five types:Type 1,erupted at the edge of nodule. Type 2,erupted at the center of nodule.Type 3,penetrated through the nodule.Type 4,contacting the nodule but stretched or encased.Type 5,contacting the nodule but smoothly compressed.The pathology type,stage,size,density and location of the peripheral lung cancer were recorded and the relationships with five types were evaluated by using Chi-square test and correlation analysis.Results (1)Tumor-bronchi relationship:type 1(33,61.1%)was more often seen in≥2.0 cm and solid lesions with stage Ⅱ-Ⅳ.while Type 2(14,25.9%)was often seen in<2.0 am and part-solid or non-solid lesions with stage Ⅰ.(2)Tumor-PA relationship:Type 1 was more often seen in≥2.0 am and solid lesions with stage Ⅱ-Ⅳ.while Type 2 was often seen in part-solid or non-solid lesions with stage Ⅰ.(3)Tumor-PV relationship:type 4 was the most common type(29,53.7%).Type 2(13,24.1%)was more often seen in part-solid or non-solid lesions.(4)Tumor-bronchi relationship and tumor-PA relationship had a positive correlation(r=0.5265,P<0.01).Conclusions MSCT can demonstrate the relations between the peripheral lung cancer and bronchi.PA and PV.It is useful for the differential diagnosis and prognosis evaluation of the lung csncer.

Objective: To investigate the effect of intrauterine intervention on severe primary fetal hydrothorax. Methods: Twelve cases with severe fetal primary hydrothorax who underwent prenatal intervention from January 2014 to December 2017 in Guangdong Women and Children Hospital were retrospectively reviewed. Results: The median gestational age of prenatal diagnosis was 30.8 weeks (24.0-33.0 weeks) . All cases were excluded congenital chromosomal abnormalities by prenatal diagnosis, and had no complications of pregnancy during prenatal diagnosis and had hydrothorax. Three cases (3/12) were right hydrothorax, the other 9 cases (9/12) were bilateral. Thoracoamniotic shunting was performed in 7 cases (7/12) . Thoracentesis was performed in 5 cases (5/12) , and the hydrothorax reappeared soon after operation in 4 cases, shunt placement was performed again. The hydrothorax was dissolved in 2 cases, released in 6 cases.Tube falling off occurred in 1 case,treatment was abandoned in 1 case and intrauterine fetal death happened in 1 case, and 1 case wasn′t rechecked by ultrasonic due to premature birth following thoracentesis. In 10 cases who had deliveries, 5 newborns (5/10) were premature, 6 newborns (6/10) underwent assisted mechanical ventilation, 8 newborns (8/10) underwent thoracic close drainage, all of them were discharged when hydrothorax resolved. Conclusions Antenatal intervention may improve the chance of survival in severe primary fetal hydrothorax. Thoracoamniotic shunting is the first-choice for the primary severe fetal hydrothorax.

Objective:To explore the influence of multidimensional integration and 360° support on the function of family and marriage, and quality of life in women patients with systemic lupus erythematosus.Methods:Totally 196 patients with systemic lupus erythematosus from Department of Rheumatology and Immunology, The Second Affiliated Hospital of the Air Force Medical University from August 2016 to November 2017 were included. According to random number table method, these patients were divided into observation group and control group as 98 cases each. Conventional care and hospital discharge were used for control group. On the basis of this, multidimensional integration and 360° support were used for patients of observation group. The function of family and marriage, quality of life in patients were assessed before and after 3 months of the intervention. The treatment adherence was evaluated in 3 months and 6 months after intervention.Results:Before intervention, the marriage family function score, marital satisfaction, conflict resolution methods and the relationship with friends and family, husband and wife exchange scores of the observation group were (2.3 ± 0.5), (24.6 ± 6.1), (25.7 ± 7.1), (28.2 ± 6.9), (28.8 ± 6.9) points, respectively. Three months after intervention, these scores were (2.5 ± 0.7), (31.6 ± 5.0), (31.7 ± 5.3), (28.1 ± 6.8), (29.0 ± 7.1) points, respectively. There was statistically significant difference between before and after the intervention ( t values were -2.371 - 8.631, P < 0.01). These scores of control group before the intervention were (2.3 ± 0.6), (24.5 ± 6.2), (25.2 ± 7.2), (32.5 ± 6.0), (33.9 ± 6.3) points, respectively. Three months after intervention, these scores were (2.3 ± 0.4), (24.5 ± 6.2), (26.1 ± 6.9), (29.1± 4.8), (28.5 ± 7.2) points. Significant differeces were found between before and after the intervention in control group ( t values were -3.878-6.323, P < 0.05 or 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 2.675-8.631, P<0.01). As for observation group, planning (62.8 ± 27.2 vs. 75.5 ± 25.4) and intimate relationship (62.8 ± 25.2 vs. 78.2± 24.9) in quality of life were obviously difference before and after 3 months of intervention ( t values were 3.050, 3.639, P < 0.01). As for control group, planning (62.5 ± 27.6 vs. 65.7 ± 24.9) and intimate relationship (65.8 ±25.2 vs. 63.5 ± 23.8) in quality of life were obviously difference before and after 3 months of intervention ( t values were 2.375, 3.132, P < 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 3.050, 3.639, P < 0.01). The treatment adherence of observation group was significant better than control group. After 6 months intervention, the treatment adherece of observation group was 83.67% (82/98), while the treatment adherece of control group was 44.89% (44/98), significant differences were found btween the two groups ( χ2 value was 0.511, P < 0.01). Conclusion:Multidimensional integration and 360° support obviously improved function of family and marriage, improved the understanding of disease, and self-management ability of patients. Therefore, it can increase the treatment adherence and improve quality of life in SLE patients.
