Objective To study the feasibility, efficacy and safety of laryngeal mask airway (LMA) in neonatal resuscitation. Methods Totally, 369 neonates requiring positive pressure ventilation at birth were randomized into two groups by offering either LMA resuscitation (205 cases) or bag-mask ventilation (BMV) resuscitation (164 cases). The effect in the two groups were observed. Results (1) No significant difference was observed in Apgar scores at 1 min between LMA group and BMV group, but the neonates having higher Apgar scores at 5 min in LMA group were more than in BMV group (x2 =-3. 39,P=0. 001). The successful resuscitation rate of LMA group was higher than that of BMV group (99.02%vs 84. 15% ,x2 =28. 76, P＜0. 01), the total ventilation time of LMA group was shorter than that of BMV group [(36.4±23.7) s vs (66.2±35.4) s] (t=-8.66, P＜0. 01). Among severe asphyxia neonates,seven of nine were successfully resuscitated by LMA, while in BMV group six neonates with severe asphyxia were all switched to endotracheal intubation ventilation. In neonates with Apgar score of 4 to 5 at 1 min after birth, the successful resuscitation rate of LMA group was higher than that of BMV group (100% vs 42. 86%, x2 =23.04, P＜0.01), the ventilation time of LMA group was shorter than that of BMV group [(54.6±33.6) s vs (136.4±42.0) s] (t= -4. 45, P＜0.01). In neonates with Apgar score of 6 to 7 at 1 min after birth, there was no significant difference in the successful resuscitation rate between LMA and BMV group. (2) The successful rate of LMA insertion at first attempt was 98.54% (202/205) and the average insertion time was (7.8 ± 2. 2) s. The adverse effects included vomiting(4 cases)and regurgitation (3 cases). Conclusions In neonatal resuscitation, LMA can be easily inserted. Compared to BMV, LMA is a better choice in resuscitation for neonates with moderate or severe asphyxia and preferable for those medical staffs who are unfamiliar with endotracheal intubation, or even as a substitute of endotracheal intubation ventilation.

Objective To analyze the clinical characteristics of narcolepsy in children with obesity,and to e-valuate the impact of obesity on narcoleptic children clinically. Methods Forty cases first diagnosed as narcolepsy were recruited in the study who to see doctors at the Department of Neurology,Children's Hospital of Capital Institute of Pediatrics,from July 2012 to January 2015. According to diagnostic criteria for obesity by the body mass index(BMI) growth curve for the Chinese children and adolescents,they were divided into the obese group and the nonobese group. The general clinical data of 2 groups were analyzed,and the related metabolic indexes and the whole night polysomnog-raphy(PSG)of 2 groups were studied. Results In this group,male versus female 3: 1,obesity was found in 21 cases (52. 5% )and nonobesity was found in 19 cases(47. 5% )from the samples. The mean BMI of all patients was (21. 55 ± 3. 11)kg/ m2 . The average BMI of the obese group was(23. 09 ± 2. 46)kg/ m2 ,and BMI of the non - obese group was(19. 85 ± 2. 89)kg/ m2 . Obese children were younger at the onset of disease and by the time of diagnosis age [(7. 94 ± 2. 22)years old,(8. 76 ± 2. 36)years old]than nonobese children[(10. 75 ± 3. 10)years old,(12. 51 ± 2. 88)years old]. The fasting blood glucose and blood lipid in all patients were normal,and there was no significant difference between 2 groups. The total sleep time,sleep efficiency and the ratio of rapid eye movement(REM)phase of the obese group[(397. 45 ± 53. 76)min,(68. 70 ± 8. 90)% ,(18. 37 ± 4. 39)% ]were significantly lower than those of the non - obese group[(449. 95 ± 86. 49)min,(76. 58 ± 13. 60)% ,(22. 19 ± 6. 34)% ]. According to the sleep structure,the percentage of stageⅠnon rapid eye movement(NREM)sleep in the obese group[(20. 90 ± 6. 38)% ] was more than that in non - obese group[(16. 26 ± 4. 22)% ]. There was no difference between the percentage of stageⅡNREM sleep in the obese group[(42. 59 ± 5. 52)% ]and the non - obese group[(38. 54 ± 8. 74)% ]. Stage Ⅲ + Ⅳ(slow wave sleep)NREM sleep ratio in the obese group[(18. 14 ± 6. 97)% ]was significantly lower than that in the non - obese group[(22. 60 ± 5. 69)% ]. Conclusions Obesity is one of the most common comorbids in narcolepsy, which affects more than 50% of narcoleptic children,mostly younger at disease onset. The narcolepsy children with obe-sity has total sleep time decreased,sleep efficiency reduced and sleep structure disorder is more obvious. To improve the realization of obesity in narcolepsy children and early treatment is the key to the success of the therapy.

ObjectiveTo investigate the related factors which influencing endoscopists in the accuracy of diagnosis of chronic atrophic gastritis (CAG). Methods With retrospective analysis method,from January to December in 2009,10 765 chronic gastritis cases underwent endoscopy examination in Renji Hospital,school of medicine,Shanghai Jiaotong University were collected.The influence of congestion and exudation,gastric ulcer,bile reflux,gastric polyps and H.pylori infection under endoscopy on CAG endoscopic and pathological diagnosis was analyzed.ResultsThe percentage of histopathological diagnosed CAG was 69.41％,endoscopic diagnosed CAG was 54.27％. The coincidence rate was 62.30％.2575 cases were H.pylori positive (23.92％),the coincidence rate between endoscopic and histopathological diagnosis in H.pylori positivc cascs was 90％.of that of H.pylori negative cases (β=-0.1067,P＜0.05).The coincidence was positively related to age.For each 1 year increase in age,the coincidence rate increased by 0.01 time [OR=exp(0.00855)=1.01]; For each 10-year increase in age,the coincidence rate increased by 0.09 time [OR=exp(0.0855) =1.09].The coincidence rate was negatively related to congestion and exudation.The coincidence rate of CAG between endoscopic and histopathological diagnosis in cases with congestion and exudation was 40％ of that without congestion and exudation (β=-0.1067,P＜0.01).ConclusionCAG diagnosed under endoscopy was somewhat subjective and should be combined with histopathological analysis.The patients' age,H.pylori infection,congestion and exudation may have influence on the coincidence rate between endoscopic and histopathological diagnosis of CAG.

Objective To explore the effect of medicated serum of Sangleng and Eshu on the expression of vascular endothelial growth factor and vascular endothelial cell proliferation induced by VEGF in vitro. Methods Medicated serum of Sangleng and Eshu was used to culture human umbilical vein endothelial cell (HUVEC-1) induced by VEGF. The morphologic changes of HUVEC-1 were observed with phase contrast microscope, and cell proliferation was detected by MTT method, and the expression of vascular endothelial growth factor protein and mRNA in endothelial cells was detected by Western blotting and RT-PCR. Results The medicated serum of 5.0, 2.5 g?kg~ -1 ?d~ -1 Sangleng and Eshu could cause arrangement disorder in the normal umbilical vein endothelial cells. The medicated serum of 5.0 g?kg~ -1 ?d~ -1 Sangleng and Eshu (10%, 5%, 2.5%) and medicated serum of 2.5 g?kg~ -1 ?d~ -1 (10%) could inhibit vascular endothelial cell proliferation remarkably (P

Objective:To explore the osteogenic effect of adipose-derived mesenchymal stem cells (ADSCs) in three-dimensional culture conditions in Matrigel hydrogel to provide theoretical basis for tissue engineering bone repair of alveolar process fractures.Methods:This study was performed in the Laboratory of Guangzhou Women and Children Medical Center in June 2019. The fourth generation of ADSCs were used to adjust the cell density to 1×10 5/mL. Two-dimensional common culture media (group A) and two-dimensional osteogenic induction media (group B) were used. The ADSCs were encapsulated in hydrogel with osteogenic induction media (group C), and the proliferation of cells was detected by CCK8 method. The cell mineralization effect was detected by alizarin red staining and alkaline phosphatase activity. The expression levels of osteocalcin (OCN) and osteopontin (OPN) were detected by qRT-PCR and Western blot assay. Results:ADSCs were encapsulated in hydrogel. The results of CCK8 kit showed that ADSCs could stably proliferate under the three-dimensional culture. The alizarin red staining and alkaline phosphatase activity of ADSCs under three-dimensional culture conditions were significantly higher than those of two-dimensional condition. In the detection of Western blotting and RT-PCR, we found that the expression of osteogenic protein and mRNA (OCN and OPN) of ADSCs in three-dimensional culture was also higher than that of two-dimensional culture.Conclusions:The encapsulation of ADSCs in hydrogel does not affect the proliferative potential of stem cells, and 3D cultured stem cells can significantly enhance their osteogenesis in vitro.

Objective To observe the ultrasonographic and pathological features of metaplastic carcinoma with squamous cell component (MCSC) of the breast.Methods The ultrasonographic and pathological features of 7 patients with breast MCSC confirmed pathologically were retrospectively analyzed.Results Seven cases were single lesion and the maximal diameters of the lesions were 2.6-5.1 cm.On two-dimensional imaging,6 lesions with cystic and solid were complex echogenic,only 1 lesion was hypoechoic.All the lesions had irregular shape (lobulated)and indistinct margin.On CDFI imaging,most of lesions had rich blood flow signals with high resistance (resistance index 0.75-0.91),4 lesions were grade l,2 lesions were grade Ⅱ and 1 lesion was grade Ⅰ blood flow signals.On gross histopathological examination,6 masses had cystic cavity,only 1 mass was pure solid.On microscopic histopathological examination,5 masses were adenosqua mous carcinoma,only 2 masses were pure squamous cell carcinoma.Estrogen receptors,progesterone receptors and human epidermal growth factor receptor were negative in 4 masses (triple-negative breast cancer).Conclusion MCSC have some distinguished ultrasonic characteristics of larger volume,cystic-solid mixed echo,posterior echo enhancement,abundant vascularity with high resistance.

AIM: To investigate the effect of dihydroartemisinin (DHA) on the proliferation of murine T lymphocytes stimulated by Con A in vitro and its related immunosuppressive mechanism. METHODS: Murine T lymphocytes were stimulated by Con A and treated with different concentrations of DHA. Cell proliferation was measured by carboxyl fluoresce in diacetate succinmidyl ester (CFDA-SE) staining. The expression of CD69, CD25 and CD71,which was the marker of early, middle, later activation of CD3~+ T lymphocytes, was measured by flow cytometry (FCM) combined with two-color immunofluorescent staining of cell surface antigen. Fluorescence calcium indicator fluo-4/AM was used to measure the change of the intracellular calcium concentration ([Ca~(2+)]_i) of murine T lymphocytes. The distribution of the cell cycle was analyzed by PI staining. The expression of CD69, the early activation antigen on CD4~+CD25~(high) Treg was also measured by FCM combined with three-color immunofluorescent staining. RESULTS: The result of CFDA-SE staining showed that DHA efficiently inhibited the Con A-induced proliferation of T-lymphocytes in a time-and dose-dependent manners. DHA showed modestly increased proportions of CD69 and CD25 on Con A-stimulated CD3~+T cells, but inhibited the expression of CD25 in a dose dependent manner. DHA with Con A, but not DHA alone, caused an increase in intracellular calcium concentration of T cells. The results of FCM analysis with PI staining showed that DHA imposed a total cell cycle arrest in G_0/G_1 and prevented cells entering S phase and G_2/M phase. Furthermore, DHA reduced the expression of CD69 on CD4~+CD25~(high) Treg. CONCLUSION: DHA, which exhibits immunosuppressive effect on the proliferation of murine T-lymphocytes, is promising to be developed as an immunosuppressive reagent.
