RESUMO
Objective To investigate the relationship between hereditary deafness and SLC26A4 gene IVS16+10C>T mutation.Methods One hundred and two patients with hereditary deafness admitted to the Third Affiliated Hospital of Qiqihar Medical College from January 2014 to May 2016 were enrolled and assigned as the observation group, and another 102 cases with normal hearing were selected as the control group. The gene mutation types and hearing thresholds were detected in the two groups and compared between them, the mutations of alleles 1 and 2 situations of patients with GJB2 and SLC26A4 mutations were analyzed, Ab initio software was used to predict whether there was obstacle preventing the recognition on slice sites, and polymerase chain reaction (PCR) was adopted to detect the common mutation types of SLC26A4 gene.Results In 102 patients with hereditary deafness, the cases caused by SLC26A4 gene mutations were more than those caused by GJB2 gene mutations (30 cases vs. 15 cases). Compared with the normal hearing control group, the mutation rates of GJB2 and SLC26A4 genes were significantly increased in the observation group [GJB2: 14.71% (15/102) vs. 2.94% (3/102), SLC26A4: 29.41% (30/102) vs. 1.96%(2/102), bothP T mutation, indicating that IVS16+10C>T gene mutation was not the cause of genetic deafness.Conclusion There is no obvious relationship between the IVS16+10C>T mutation of SLC26A4 gene and patients with hereditary deafness, which may provide a basis clinically for the prediction of deafness occurrence in the patient's next generation.
RESUMO
Objective:To explore the effect of early mother to child separation on neonatal nervous system and its related mechanism.Methods:Randomly selected during January 2015 to September 2015,was born in 120 cases of newborn mice as the research object,the newborn mice was born after the implemented of mother-to-child separation as observation group (60),not the implemented of separation of mother and baby after birth as the control group (60),in view of the two groups of newborn mice of the nervous system,the change of the nerve cells were compared and researched.Results:The apoptotic rate of neurons in the neonatal mice was significantly higher than that in the control group (P ＜0.05).The neurons of caspase-3 protein expression was significantly higher than the control group (P ＜0.05).The expression of Caveo-1 protein in the glial cells of 14 days and 21 days was observed in the neonatal mice.The expression of Caveo-1 protein in the glial cells of the control group For comparison,(P ＜0.05),which were statistically significant.Conclusion:The early implementation of matemal and infant birth separation of neonatal nervous system will produce great influence,and influence the expression of the nervous system in the development of newborn,which affect the behavior of the neonatal adult dysplasia.
RESUMO
Objective To observe the clinical effect of Danggui Sini decoction for treatment of patients with chronic non-atrophic gastritis and spleen-stomach deficiency cold syndrome.Methods A prospective randomized control trial was conducted, including 126 in- and out-patients with chronic non-atrophic gastritis diagnosed by gastroscopy and spleen-stomach deficiency cold syndrome differentiated by traditional Chinese medicine (TCM) method admitted to Chinese Medicine Hospital of Haikou City. They were randomly assigned to an observation group (65 cases) and a control group (61 cases). The patients in observation group were given Danggui Sini decoction with addition or/with subtraction of ingredients according to individual situation (ingredients: angelica 15 g, ramulus cinnamomi 15 g, paeonia 15 g, asari 5 g, glycyrrhizae 10 g, Chinese jujube 12, medulla tetrapanacis 10 g ). The warm 200 mL (one dose) decoction was divided into two parts, one part was taken orally before a meal, twice daily, the therapeutic course was 4 weeks and in one week only 6 doses were applied; while the patients in control group, omeprazole capsules (dissolved in intestine), each time 20 mg, once a day combined with domperidone (bite phenanthroline) 10 mg each time, 3 times a day were given. After 4 weeks of treatment, the clinical efficacy, the total integral of symptoms, the therapeutic effect of TCM symptoms score, the improvement of the therapeutic effect of mucosal histological and changes of the number of patients with the patholoyical changes of mucosa under gastroscopy were observed.Results The total effective rate in the observation group was significantly higher than that in the control group [96.9% (63/65) vs. 86.9% (53/61),P < 0.05]. After treatment, the total integral of symptoms and the integrals of main TCM symptoms after treatment were lower than those before treatment, the degree of decrease in the observation group being more marked (the total integral of symptoms score: 12.36±2.11 vs. 15.94±2.37, epigastric distention integral score: 1.23±0.72 vs. 2.12±0.78, epigastric pain score: 1.18±0.67 vs. 2.25±0.94, thermophilic and like pressure integral score: 1.03±0.46 vs. 1.62±0.79, anorexia: 1.06±0.57 vs. 1.43±0.53, integral of loose stools score: 1.36±0.43 vs. 1.67±0.58, lassitude integral score: 1.24±0.32 vs. 1.65±0.42, allP < 0.05). Under gastroscope, the efficacy of mucosal histological change was significantly higher in observation group than that in control group [90.77% (59/65) vs. 81.97% (50/61),P < 0.05]. After treatment, the numbers of patients with chronic inflammatory cell infiltration (47 cases vs. 54 cases), erythema exudation (28 cases vs. 30 cases), flat erosion (8 cases vs. 15 cases), swelling erosion (5 cases vs. 6 cases), bile reflux (2 cases vs. 3 cases) and positive pylorus spirobacteria (20 cases vs. 29 cases) were significantly lower in the observation group than those in the control group (allP < 0.05).Conclusion The therapeutic effects of Danggui Sini decoction for treatment of patients with chronic non-atrophic gastritis and TCM syndrome of spleen-stomach deficiency-cold are remarkable.
