Objeetive To investigate the reliability,validity and clinical value of Chinese version of the reflux symptom index(RSI).Methods xThe Chinese version of RSI scale was used in ENT outpatient department.There were one hundred and seven patients,including thirty-five patients with common throat diseases (non-suspected) and seventy-two patients with clinically suspected throat reflux.All 107 patients were asked to complete the two scales one on the first-visiting and one after one week.Thirteen patients with common throat diseases (non-suspected) and forty-one with suspected throat reflux also received RSI testing.Among the thirty-four confirmed acid reflux disease patients,thirty patients received pharmaceutical treatments and self-performed post-RSI testing after three months.Results The RSI Scale internal reliability consistency included the test-retest reliability (0.715-0.971),discriminant validity and construct validity.RSI total targeting percentage was 66.7％,targeting percentage was 80.8％.Discriminant validity was confirmed using 2 independent samples Wilcoxon test,with RSI total score compared to Z =-3.266,P =0.001.The before and after treatment self-control chi-square test (P ＜ 0.05),the difference was statistically significant.Conclusion RSI Simplified Chinese version has good rcliability and validity,and can be used for laryngopharyngeal reflux disease (LPRD) diagnostic screening along with the efficacy for the treatment of patients with appropriate LPRD aids.

OBJECTIVETo establish an easily reproducible animal model of hypospadias and to test whether Atrazine can induce hypospadias in animal experiment.

METHODSFrom the 11th to 16th day after conception, 120 conceived SD rats were divided randomly into 6 groups: one coin oil group (1 ml/kg/d), two finasteride groups (10 mg/kg/d, 20 mg/kg/d), three Atrazine groups (25 mg/kg/d, 100 mg/kg/d, 200 mg/kg/d). When all pregnant rats had delivered, the new born rats were counted and the penis appearance, urethral orifice position and micturition were observed with magnifying lens and anatomy microscope.

RESULTSHypospadias were found in new born male rats treated prenatally with Finasteride (10 mg/kg/d, 20 mg/kg/d) and 200 mg/kg/d Atrazine groups. The incidence was 28.30%, 67.03%, 10.23% respectively. Embryotoxic effects were observed at 25 mg/kg/d Atrazine group in 2 rats and associated with no severe maternal toxicity.

CONCLUSIONS(1) A hypospadias SD rats model can be established by Finasteride and it is easily reproducible. (2) The Atrazine was teratogenic to the SD rats, embryotoxic effects were observed at the low dose level and associated with no severe maternal toxicity.

OBJECTIVETo screen gene mutation in alpha-galactosidase A (alpha-Gal A) in a nonconsanguineous Chinese family with Fabry disease (FD) with clinical manifestations similar to hypertrophic cardiomyopathy (HCM).

METHODSMutation analysis was performed by using purified PCR products to direct sequence analysis on an ABI-377XL automated DNA sequencer. DNA analysis of alpha-Gal A gene and physical and clinical examinations were performed in a female proband and in her relatives (15 subjects in total).

RESULTSThree hemizygotes and 6 heterozygotes were diagnosed for FD by the alpha-Gal A gene analysis with a missense mutation in exon 5 of the alpha-Gal A sequence, leading to a TGG32TGA substitution, which may induce the absent of tryptophan's translation (corresponded to TGG) by the terminator codon TGA. Six patients in the family were revealed as HCM by echocardiography.

CONCLUSIONSPresent results show that it is important to differentiate FD from other causes of hypertrophy in patients with cardiac hypertrophy. Screening for alpha-Gal A gene mutations in patients with FD and in their relatives could help to identify all suspected cases within the families.

Objective:To investigate the clinical pathological and epidemiological characteristics of primary esophageal malignant melanoma (PMME).Methods:The clinical pathology data of 180 PMME patients in the esophageal cancer database of the key laboratory of esophageal cancer research in Henan Province from 1973 to 2016 were collected, of which 136 were male, aged (58.5±9.0) years, 44 were female, aged (56.7±12.2) years. Kaplan-Meier and Log rank test were used for survival analysis, Cox regression scale model was used for risk factor analysis.Results:The incidence of PMME is 0.036% (180/500, 000), mostly were male (about 3∶1 for men: female). The common sites of PMME were the lower part of the esophagus (48.9%, 85/174), followed by the middle section of the esophagus (46.0%, 80/174) and the upper part of the esophagus (5.2%, 9/174). No black particles were seen in the PMME cells of 3 patients under microscope, and strong positive expressions of Melan-A and HMB453 were observed in these 3 patients by immunohistochemical results. Of the 129 patients who had a routine preoperative esophageal biopsy, 69 were undiagnosed with PMME (53.5%). The medium survival time of the whole group was 7.9 months, and the survival rates of 1, 2, 3, 5 years were 25.0%, 7.9%, 6.6% and 1.3%, respectively. The univariate analysis showed that N, M, TNM phase and radiotherapy were related to the overall survival of patients ( P<0.05). Multivariate analysis showed that TNM phase and radiotherapy were the independent risk factors for overall survival of patients ( P<0.05). Conclusions:PMME is more common in men, the common site of the disease is the lower part of the esophagus. The preoperatively missed diagnosis rate of Chinese PMME is high. TNM phase and radiotherapy are the independent risk factors for overall survival of patients.

Aim To explore the mechanism of action of the active ingredients of Callerya nitida var.hirsutissima corresponding to the target gene in the treatment of triple-negative breast cancer(TNBC), using network pharmacology, molecular docking technology and in vitro experimental verification.Methods Based on literature research and combined with database screening, the main active components of Callerya nitida var.hirsutissima and the related targets of TNBC were obtained.Intersection genes were found to construct a protein interaction(PPI)network diagram, and core targets were screened according to the size of the correlation.A core target interaction network model of "Traditional Chinese Medicine-Ingredients-Targets-Disease" was constructed.The intersection targets were analyzed for gene GO function and KEGG pathway enrichment analysis.Finally, molecular docking and in vitro experimental verification of the selected components and the target were carried out.Results A total of 38 active components of Callerya nitida var.hirsutissima were collected, as well as 388 related potential targets, 3 919 TNBC targets, and 277 Callerya nitida var.hirsutissima therapeutic targets for TNBC.It mainly acted on multiple targets such as PIK3R1, PIK3CA, MAPK1, AKT1, SRC, etc.In in vitro experiments, it could be seen that the chloroform fraction of Callerya nitida var.hirsutissima and the monomer compounds luteolin and betulin had certain inhibitory effects on cell proliferation.All groups could inhibit the expression of VEGFA, AKT, PIK3CA, CDK1, CDK4 within the range of administration concentration.Conclusions Based on network pharmacology and molecular docking methods, this study explores the possible targets and signaling pathways of Callerya nitida var.hirsutissima in the treatment of TNBC, and conducts in vitro verification experiments to further verify the prediction of network pharmacology.
