OBJECTIVE: To explore the clinical manifestations in pediatric laryngopharyngeal reflux and to provide more information on diagnosis and treatment. METHOD: Sixty-two cases with recurrent respiratory infections, hoarseness and chronic cough were examined with reflux symptom index (RSI), reflux finding score (RFS), and 24-hour pH monitoring. Those who had at least two positive test for reflux were given PPI for diagnostic therapy. RESULT: All patients completed reflux symptom index (RSI) questionnaire and underwent fiberoptic laryngoscopy, and reflux finding score (RFS) was evaluated. The positive rate of RSI and RFS was 91.94% and 79.03% differently. 24-hours pH monitoring and diagnostic therapy was about 30.76% and 85.48% differently. The symptoms show hoarseness 90.32%, postnasal drip 77.42%, difficulty swallowing 74.19%, abdominal pain and chest pain 72.58%, throat clearing 64.52%, chronic cough 56.45%, dysphagia 51.61%, throat abnormal feeling 48.39%. Laryngoscope examination shows inter-arytenoid erythema 100%, vocal mucosal oedema 75.81%, diffuse laryngeal edema 50.00%, posterior commissure hypertrophy 33.87%, subglottic edema 4.84%, no granuloma case. There was 16 cases showing positive in 24-hours pH monitoring test. The positive rate was 30.76%. All cases accepted diagnostic therapy. Fifty-three cases were effective. The positive rate was 85.48%. CONCLUSION There are no clinical presentations specific to pediatric laryngopharyngeal reflux. Patients often present with a wide range of atypical symptoms and signs. RSI questionnaire and RFS may provide diagnostic datas. Primary treatment includes lifestyle and medical therapy.

Objective To investigate the effects of the interaction between human hepatoma cells and hepatic stellate cells on their growth state,and study its role of interaction on the progression of hepatocellular carcinoma.Methods Human hepatoma cell line HepG2 and hepatic stellate cell line hepatic stallate cells (HSC)-T6 were used and the methods including methyl thiazolyl tetrazolium (MTT) assay,flow cytometry (FCM) analysis,immunohistochemistry,and electron microscopy were employed in this experiment.The effects of conditioned medium (CM) of HepG2 on the activation and proliferation of HSC were explored.The effects of activated HSC CM on HepG2 proliferation were investigated.The uhrastructural changes of the two co-cultured cells were observed.Results MTT assay result showed that HepG2/HSC CM could promote HSC/HepG2 proliferation.FCM result demonstrated that HepG2/HSC CM could influence the cell cycle distribution in HSC/HepG2.Immunohistochemistry exhibited that after the treatment of HepG2/HSC CM,the expression ofα-smooth muscle actin (α-SMA) in HSC and proliferating cell nuclear antigen (PCNA) in HepG2 were increased.When HepG2 and HSC were co-cultured,the ultrastructure of HSC displayed an activated feature.Conclusions HepG2 cells can induce the activation and proliferation of HSC,and the activated HSC can also stimulate the proliferation of HepG2.Interaction between hepatoma cells and hepatic stellate cells may play an important role in the progression of hepatocellular carcinoma.

Objective To observe the effects of acupuncture therapy on triglyceride (TG) content of quadriceps femoris in the high fat diet feeding-induced insulin resistance rats; To discuss acupuncture mechanisms to improve the insulin sensitivity. Methods Thirty-two Wistar rats at the age of eight weeks were randomly divided into normal group, model group, electro-acupuncture group, and sham electro-acupuncture group. The normal group was given basic diet, and model group, electro-acupuncture group and sham electro-acupuncture group were given high fat diet for 8 weeks, after which, the model of insulin resistance was successfully obtained. Electro-acupuncture group was given acupuncture therapy with “Guanyuan (GV4)”, “Zhognwan (GV12)”, “Zusanli (ST36)”, and “Fenglong (ST40)” for 8 weeks. Sham electro-acupuncture group was given stimulation at non-acupuncture points which were not on the meridians and near the acupoints but not at the area of the acupoints. In addition, food intake and body weight of each group were recorded, blood glucose was tested, TG content of quadriceps femoris was measured by enzymatic method after the treatment. Results The weight of the rats and TG levels of quadriceps femoris in electro-acupuncture group and sham electro-acupuncture group were significantly lower than those in model group, with significant statistical difference (P<0.05), especially in electro-acupuncture group. Conclusion Acupuncture therapy could improve insulin sensitivity to prevent and its related diseases.

OBJECTIVE: To investigate the clinical pathological features of children tracheobronchial foreign bodies and to improve diagnosis and treatment. METHOD: A retrospective study 368 children cases with tracheobronchial foreign bodies in our hospital. Each patient was analyzed for age, sex, nature,complication and location of the foreign body, results of bronchoscopic removal and presence of foreign bodies in the airways. Among this cases, three of them coughed out the foreign body before operation; two of them failed to be operated for serious complication, others were conducted by rigid bronchoscopy and bronchoscopic removal with general anaesthesia. RESULT: Three children of 368 coughed out the foreign body before operation; 4 children of them were dead for the long heartbeat respiratory arrest and deep coma; 2 children of them suffered form hypoxic ischemic encephalopathy and epilepsy; others were successfully taken out by operation. CONCLUSION For the diagnosis of children cases with tracheobronchial foreign bodies, it is very important to collect the detailed history of foreign body inhalation, physical examination and careful analysis on the findings from chest radiographs or CT scan.

Objective To analyze and discuss the specific effect and mechanism of Guizhi Fuling pill on angiogenesis in rats with endometriosis. Methods A rat model of endometriosis was established in 40 rats in the same batch, they were randomly divided into 4 groups. The model control group did not give any drugs; the low dose of Guizhi Fuling pill group was given 0. 5 g Guizhi Fuling pill every day; the high dose of Guizhi Fuling pill group was given 3. 0 g cinnamon Fuling pill every day; gestation three ketone group was given three ketene 2 g every day. After 4 weeks of continuous administration, the rats were killed and the expression of VEGF and HIF-1 alpha in the rats was determined. The mechanism of Guizhi Fuling pill in the treatment of endometriosis was determined through the expression of VEGF and HIF-1α. Results Guizhi Fuling pill significantly inhibited the level of intravascular VEGF in rat endometriosis and inhibited the level of mRNA expression of HIF-1α. Conclusion Guizhi Fuling pill can inhibit the angiogenesis of endometriosis, and its mechanism is related to the inhibition of VEGF and HIF-1 alpha.

The effects of A-L tonic capsule on DNA content in rat experimental hepatocarcinogenesis induced by diethylnitrosamine (DENA) were observed. The experimental rats were divided into 4 groups. With exception of group D in which the rats were only administered with DENA, the rats in the groups A, B, C were previously, simultaneously and subsequently fed with A-L tonic capsule respectively while they were administered with DENA. The DNA content of all rat livers was measured using automatic image analysis technique 20 weeks after administration of DENA. The results showed that the highest and lowest DNA contents were respectively seen in the groups D and A. There was significant difference in DNA contents between the groups A or B or C and D, and also between the groups A and B or C (both P < 0.01). 4 components (4C) and > or = 5C cells were predominant in the group D, while 2C cells were the minority. The number of 2C cells in the groups A, B, C was significantly higher than that in the group D, and the number of > or = 5C cells in the groups A, B, C was markedly lower than that in the group D (P < 0.01). Also, there was very significant difference in the number of 2C and > or = 5C cells between group A and B or C (P < 0.01). It was concluded that A-L tonic capsule could effectively inhibit the increase of DNA content of hepatocytes and improve the distribution of DNA content in rat hepatocarcinogenesis, especially in group A.

Objective To analyze the clinical characteristics,diagnostic and treatment principle of orbital cellulitis in children,and to improve the experience of antibiotic treatment in orbital cellulites.Methods Twenty children were admitted to Shenzhen Children's Hospital with the diagnosis of nasal orbital cellulitis between January 2009 and December 2013.The children were severe enough to warrant hospital admission.There were 13(65％) males and 7 (35％)females.The median age was 3.5 years (2 months to 7.2 years).The relationship between the serum C-reactive protein (CRP),white blood cell count and the hospitalization days were analyzed.The children were divided into 2 groups:Cefoperazone Sodium and Sulbactam Sodium for injection group and other antibiotic treatment group,the difference was compared.Statistical calculation was performed using SPSS 13.0 software.Results The serum CRP [(29.8 ± 22.0) mg/L] at the time of admission had a positive correlation with the time of hospitalization[(6.3 ±4.1) d,r =0.46,P ＜ 0.05].The time of CRP decreased to normal range after admission [(3.4 ± 1.8) d] were apparently related to the hospitalization time (r =0.81,P ＜0.01).The hospital days whose CRP could be decreased to normal within 3 days [n =12,(4.3 ± 1.7) d] were significantly shorter than that in the others [n =8,(9.1 ± 5.0) d,t =2.61,P ＜ 0.05].The hospitalization of 12 cases with Cefoperazone Sodium and Sulbactam Sodium for injection[(4.3 ± 1.9) d] was shorter than that in other 8 cases with other drugs [(9.3 ± 4.7) d,t =2.83,P ＜ 0.05].Bacterial pathogens were only identified in 4 children,including 3 cases of methicillin-resistant staphylococcus aureus (MRSA),1 case of streptococcus anginosus.Only 1 case in 20 cases with positive blood culture for Staphylococcus aureus,consistented with the pus culture.Conclusions If early treatment at the first three days is valid,the course of nasal orbital cellulitis will be shorter and the orbital abscess can be prevented.Cefoperazone sulbactam and Sulbactam Sodium for injection is effective in treating pediatric orbital cellulitis.

Laryngeal clefts as exceptionally rare congenital anomalies have been reported more and more recently. The clinical symptoms and presentations base on degree of clefts and variety of comorbidities. Mild types of clefts may have minimal clinical impact, whereas severe types may be life-threatening and even lead to death before diagnosis. With more attention of these anomalies and advances in endoscopy, the diagnosis, evaluation and surgery of laryngeal clefts have acquired great improvement, especially International Pediatric Otolaryngology Group(IPOG)have reported consensus guidelines on the diagnosis and management of type Ⅰ laryngeal clefts in 2017. This review of laryngeal clefts may be beneficial to decrease missed diagnosis or misdiagnosis and to achieve individual-based treatment.
