OBJECTIVE:
To discuss the diagnosis and treatment method in children with mass in subglottic.
METHOD:
There were totally 35 patients with subglottic mass who complained with dyspnea in our department. All the patients got electronic laryngoscopy examination in order to get the preliminary judgment of the mass' property. Then they accepted ultrasound and CT scan to make the definite diagnosis. The patients with subglottic hemangioma accepted oral propranolol or intralesional Pingyangmycin injection. The other type of masses got the laryngoscope CO2 laser tumor resection.
RESULT:
There were 31 patients with subglottic hemangiomas, 2 patients with subglottic cysts, 1 patient with subglottic fibroma, 1 patient with subglottic granuloma. The substantial follow-up time was from 1 month to 3 years. 25 patients with subglottic hemangiomas were cured, 6 patients got improvement. The patients with non-hemangiomas were all cured.
CONCLUSION
There was a high incidence of hemangioma in children with subglottic mass. We suggested making a diagnosis by doing electronic laryngoscopy, ultrasound and CT scan step by step. Oral propranolol was a safe and effective method in treating subglottic hemangioma. For the patients with non-hemangiomas, we considered the laryngoscope CO2 laser tumor resection as the first choice of treatment.

OBJECTIVE To discuss the diagnosis and endoscopic treatment of congenital basal encephaloceles in infants.METHODS We retrospectively reviewed the clinical data of 6 infants with congenital basal encephaloceles in Beijing Children's Hospital between January 2014 to September 2016. CT and MRI were performed routinely. All patients underwent endoscopic resection of encephaloceles and repair of skull base defects. RESULTS Five patients presented with transethmoidal encephaloceles and one transsphenoidal encephaloceles. All patients underwent endoscopic procedure successfully. There were no complications except for one 7-month old girl who got purulent meningitis. All patients had favorable clinical outcomes during a follow-up of 3 to 29 months.CONCLUSION For infants with persistent nasal obstruction and nasal neoplasms, congenital basal encephaloceles should be considered. Nasal coronary CT and sagital MRI are of paramount importance in the diagnosis of congenital basal encephaloceles in infants. The endoscopic procedure is the safe and effective method for the management of congenital basal encephaloceles in infants.

OBJECTIVE To investigate the short-term clinical efficacy of sublingual immunotherapy in children with allergic rhinitis. METHODS Forty-four patients, from 3-14 years of age, with mite-sensitive allergic rhinitis were treated sublingually with standardized dermatophagoidesfarinae extract. After treatment of 3 or 6 months using the dermatophagoidesfarinae extract, the total nasal symptoms score(including nasal congestion, nasal itching, rhinorrhea and sneezing scores), total rhinitis medicine scores, visual analog scale scores and the percentage of blood eosinophilic granulocyte(Eos%) before and after treatment were evaluated. SPSS 20.0 software was used to analyze the data. RESULTS After 3 or 6 months' treatment,thenasal symptoms score(including nasal congestion, nasal itching, rhinorrhea and sneezing scores), total rhinitis medicine scores and visual analog scale scoreshad significantly reduced,comparing with that before treatment(all P<0.05). The comparison of the total nasal symptoms score(including nasal congestion, rhinorrhea and sneezing scores), total rhinitis medicine scores and visual analog scale scores between 3 months and 6 months treatment had shown no significant difference (all P>0.05), while nasal itching scores had significantly reduced(Z=-4.185, P<0.05). After 6 months' treatment, the percentage of Eos% had significantly reduced compared with that before treatment(Z=-4.544, P<0.05). CONCLUSION SLIT could be an effective treatment in patients with allergic rhinitis sensitive to house dust mite. It would have effect after3 months treatment and Eos%reduced significantly after 6 months treatment.

Objective To evaluate the accuracy of thoracic pedicle screw placement using the "funnel technique" and investigate its consistency in experimental study and clinical application.Methods The clinical data of three human cadavers and 11 patients with the installation of at least one thoracic pedicle screw at T1 -T12 from August 2006 to July 2008 were retrospectively analyzed. One junior spine surgeon lack of experience were responsible for placing these screws with the "funnel technique".The accuracy of screw placement and the complications related to the use of thoracic pedicle screws were analyzed by assessing postoperative CT scans. Results The mean follow-up time was 23.1 months,which showed no vascular or visceral complications, or iatrogenic neurological injury. The rate of unintended cortex perforations was 14% (10/72) in cadavers and 15% (8/55) in patients, respectively.The critical perforation occurred in two screws (3%) in cadavers and one screw (2%) in patients. There was no statistical difference between the percentage of cortex perforations in cadavers and patients. Of all the 11 patients, screw violation occurred laterally in six ( 11% ), medially in one ( 2% ) and superiorly in one (2%). No violations occurred inferiorly or anteriorly. For all patients, only one screw needed revision. The perforations made by the junior spine surgeon occurred in six screws in the first cadaver, three in the second cadaver and one in the third cadaver. Conclusions The "funnel technique" is a simple,safe, accurate and cost-effective technique for pedicle screw placement. The result of the experimental study is consistent with that of the clinical application. "funnel technique" is helpful for junior spine surgeons to master the technique of thoracic pedicle screw placement.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

Objective:To determine the effects of cytochrome P450 1A1 (CYP1A1) on nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages and the underlying mechanism.Methods:The peritoneal macrophages (PMs) were isolated from healthy C57BL/6 mice and stimulated with 10 mg/L LPS to establish inflammatory response model. The CYP1A1 mRNA and protein expressions in the cells were determined. The mouse macrophages RAW264.7 cell line with CYP1A1 overexpression (CYP1A1/RAW) were cultured in vitro, and they were stimulated by 10 mg/L LPS at logarithmic phase. The negative control-expressed RAW264.7 cells (NC/RAW) were established. The protein and mRNA expressions of activator protein-1 (AP-1) and inducible nitric oxide synthase (iNOS) in the cells as well as the content of NO in the cell supernatant were determined. The RAW264.7 cells were cultured in vitro, and they were stimulated by 10 mg/L LPS and 100 nmol/L 12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE] only or in combination at logarithmic phase. The blank control group was set up. The expression of iNOS mRNA in the cells and NO content in the cell supernatant were determined to observe whether the effect of CYP1A1 on LPS induced NO production in macrophages was related to 12(S)-HETE produced by metabolism. The RAW264.7 cells with CYP1A1 overexpression and hydroxylase activity mutation (CYP1A1m/RAW) were cultured in vitro, and they were stimulated by 10 mg/L LPS at logarithmic phase. The CYP1A1/RAW cell control group was set up. The iNOS mRNA expression in the cells and NO content in the cell supernatant were determined to observe the effect of hydroxylase activity of CYP1A1 in regulating NO production in macrophages. Results:Compared with the phosphate buffered saline (PBS) control group, the CYP1A1 mRNA expressions were elevated significantly from 2 hours after LPS stimulation and reached a peak at 12 hours [CYP1A1 mRNA (2 -ΔΔCt): 6.41±0.98 vs. 1.00±0.00, P < 0.05], while CYP1A1 protein expressions were increased from 6 hours after LPS stimulation and reached a peak at 24 hours, suggesting that CYP1A1 expression might be involved in LPS-induced macrophage over-activation. Compared with NC/RAW+LPS group, the iNOS mRNA expressions and NO contents both increased in CYP1A1/RAW+LPS group and reached a peak after 12 hours and 24 hours, respectively [12-hour iNOS mRNA (2 -ΔΔCt): 54.42±8.21 vs. 24.22±3.89, 24-hour NO (μmol/L): 66.52±4.09 vs. 41.42±2.09, both P < 0.05], while the iNOS protein expression and AP-1 phosphorylation also enhanced, suggesting that CYP1A1 might increase NO production by promoting AP-1 activation and iNOS expression. LPS and 12(S)-HETE stimulation only or in combination had no effect on iNOS mRNA expression and NO production, and no significant difference was found between the 12 (S)-HETE+LPS group and LPS group [12-hour iNOS mRNA (2 -ΔΔCt): 34.24±4.07 vs. 34.35±4.01, 24-hour NO (μmol/L): 44.02±3.14 vs. 44.56±3.21, both P > 0.05], suggesting that the regulation of CYP1A1 on NO production might not be induced by 12 (S)-HETE. There was no significant difference in the iNOS mRNA expressions or NO content between the CYP1A1m/RAW+LPS group and CYP1A1/RAW+LPS group [12-hour iNOS mRNA (2 -ΔΔCt): 52.11±6.84 vs. 50.21±5.19, 24-hour NO (μmol/L): 60.42±4.14 vs. 52.01±5.12, both P > 0.05], suggesting that CYP1A1 hydroxylase activity deficiency showed no effect on NO production. Conclusions:LPS stimulation significantly increases CYP1A1 expression in macrophages. CYP1A1 overexpression promotes NO production by activated macrophages through AP-1/iNOS pathway, while hydroxylase-deficiency or 12(S)-HETE has no effect on this regulation.

Infectious and inflammatory diseases are important diseases threatening human health. Without timely control, a series of complications will occur in patients, such as sepsis, inflammatory factor storm, and even lead to death. It has been found that cytochrome P4501A1 (CYP1A1) plays a key role in the development of infectious and inflammatory diseases through aromatic hydrocarbon receptor (AhR) dependent and non-dependent pathways in different cells and organs induced by different substances. The non AhR dependent regulatory mechanism of CYP1A1 and the different roles of CYP1A1 in infection and inflammation is reviewed in order to provide reference for further research on the relationship between CYP1A1 and infection and inflammation.
