Objective To investigate and to analyze the extend,structure,regional distribution,and causes of the hearing disability in Guangxi,from the information gathered from the second national sample survey among the disabled;to evaluate the present situation of hearing disability among Guangxi residents;and to provide basis for setting up effective preventing and intervening program for the hearing disabled.Methods The sampling methods was used to carry out a selective examination among 200 sample areas,including 25 counties and 100 villages.There were about 400 residents in each area,22 569 families,80 712 people involved in the survey with the sampling rate of 1.730%.The standard time began at 0 o'clock,April 1st,2006.Results Among the 5 837 disabled,1 467 were hearing disabled,accouting for 25.13% of the total.70 were grade 1 hearing diability(4.770% of the total number of the disabled);127 were of grade 2 hearing diability (8.660% of the total number of the disabled);689 grade 3 hearing diability (46.98% of the total number of the disabled);581 grade 4 hearing diability(39.600% of the total number of the disabled).The distribution of primary causes indecated that 911 were age related hearing loss,accounting for 62.10%;155 had unknown cause,accounting for 10.570%;158 ontological disease,accounting for 10.770%;111 systemic disease,accounting for 7.57%;132 had other reasons,accounting for 8.99%.Among all,821 were male (560%),646 were female (440%).The gender ratio was 1.27:1.910 were rural residents (620%),557 urban residents (38%).The age distribution was:3 under six (0.20%),10 from 7 to 17 (0.68%),215 from 18 to 59 (14.66%),1 239 over 60 (84.46 %).Conclusion Hearing disability is of the highest incidence among all kinds of disability in Guangxi.Most of the hearing impaired are associated with age and ear disease.Therefore prevention,education and treatment can help reduce the incidence of hearing disability.

Objective:To study the expression of E-cadherin and P120ctn in nasopharyngeal carcinoma tissues, and to investigate their relationship and the relation with clinico-pathological features. Methods Two-step immuno-histochemical staining was applied to detect the expression of E-cadherin and P120ctn in formalin fixation and paraffin-embedded specimens from 56 cases with nasopharyngeal carcinoma and 15 cases with normal nasopharyngeal epithelia. Result:The abnormal expression rates of E-cadherin and P120ctn in the 56 cases of NPC tissues were 64.29% and 67.86% respectively, mainly with reduction of expression membrane and with the expression of cytoplasm; 6.67% of the 15 comparative normal cases of nasopharyngitis had abnormal expression of E-cadherin and P120ctn The differences were statistically significant. The abnormal expression rates of E-cadherin and P120ctn in NPC tissues were 71.43% and 85.71% respectively in low differentiated cancer group, which was obviously higher than the rates-42.86% and 36.29%-in high and middle differentiated cancer group. The 80.00% and 85.00% abnormal expression rate in the group with cervical lymph node metastases was higher than that in the group without cervical lymph node metastases(52.78%, 58.33%). The abnormal expression rate of E-cadherin and P120ctn(76. 92%,84.62%) in the third and forth phases was higher than that in the first and second phases (46.66%, 53. 33%). The differences were statistically significant (P<0.05). There were all together 12 co-expression cases of P120ctn and E-cadherin and 28 abnormal co-expression cases in the 56 cases of NPC tissues, which was of obvious consistency and correlation, with the relevant indexes: rs=0.5217 and P<0.01. Conclusion: The abnormal expression of E-cadherin and P120ctn is closely related to the degree of differentiation, clinical stage and cervical lymph node metastasis, and they join in the process of NPC initiation, progression, invasion and metastasis.

Objective To evaluate the predictive value of N-terminal-pro-brain natriuretic peptide (NT-proBNP) in weaning patients from mechanical ventilation (MV).Methods Data of 42 patients supported with MV in intensive care unit (ICU) admitted to the Rui Jin Hospital from January through December in 2014 were retrospectively analyzed,and the causes for MV were recorded.According to the outcomes of weaning from MV after 48 hours,the patients were divided into two groups namely success group and failure group.Comparisons of fluid balance in 72 hours before spontaneous breathing trial (SBT),and comparisons of NT-proBNP1 levels at admission,NT-proBNP2 levels before SBT,NT-proBNP3 levels after 48 hours after SBT between two groups were carried out.And the receiver operating characteristic (ROC) curve for predicting weaning rate was plotted to find the optimal cut-off point of NT-proBNP2.Results In the total of 42 patients,there were 27 cases in success group and 15 cases in failure group.There were not statistically differences of NT-proBNP1 levels between success group and failure group (P =0.121).However,the NT-proBNP2 levels and NT-proBNP3 levels in failure group were significantly higher than those in success group (P =0.01,0.003).The area under curve (AUC) of the ROC curve of NT-proBNP2 levels to predict the failure of weaning was 0.862 (95％ CI:0.753-0.971).When the optimal cut-off point of NT-proBNP2 was 715.5 pg/mL,the sensitivity and specificity were 93.3％ and 74.1％,respectively.Conclusion The NT-proBNP2 levels before SBT have predictive value in weaning rate,and it can be used as one of the screening indicators for weaning.

Objective To explore the effect of Taijiquan on motor function and depression in patients with post-stroke depression. Meth-ods From January to October, 2015, 60 stroke patients with depression were randomly divided into control group (n=30) and Taijiquan group (n=30). Both groups accepted routine rehabilitation, while Taijiquan group accepted another training of six actions from simplified Taijiquan. They were assessed with Fugl-Meyer Assessment (FMA), Barthel Index (BI) and Hamilton Depression Rating Scale (HAMD) be-fore, and four and eight weeks after treatment. Results The scores of FMA and BI increased more in Taijiquan group than in the control group after treatment (t>2.351, P<0.05), while the score of HAMD decreased more (t>2.169, P<0.05). Conclusion Taijiquan can relieve the depression and improve the motor and activities of daily living in patients with post-stroke depression.

Objective The effectiveness of Zhuang nationality medical lotus needle plus back cupping therapy ( Zhuang needle-cupping therapy) , Flixonase aqueous nasal spray and cetirizine tablets in treating allergic rhinitis (AR) was compared for the exploration of the therapeutic mechanism of Zhuang needle-cupping therapy. Methods A total of 200 recruited AR patients were randomly divided into four groups in the proportion of 1:1:1:1. The four groups were Zhuang needle-cupping therapy group, cetirizine group, Flixonase group and blank control group. The blank control group had no medication, and the patients of the other three medication groups were given the corresponding treatment. Ten days constituted one treatment course, and interval between two courses lasted one week. After two courses, the therapeutic effect was evaluated. The changes of specific IgE (S-IgE), leukotriene (LT), interleukin 4(IL-4), IL-9 mRNA, interferon gamma (IFN-γ), Thl / Th2 cells, and Th17 cytokine ( IL-17) were observed before and after treatment. Results ( 1) After two treatment courses, Zhuang needle-cupping therapy group had better therapeutic effect than cetirizine group , Flixonase group and blank control group, and the therapeutic effect of cetirizine group and Flixonase group was better than the blank control group (P<0.05). However, the therapeutic effect of cetirizine group was similar to that of Flixonase group ( P>0.05). ( 2) After treatment, the levels of S-IgE, LT, IL-9 mRNA, IL-4 and IL-17 were decreased, and IFN-γ and Th1/Th2 levels were increased in the three medication groups ( P<0.05 compared with those before treatment) . The differ ences of the laboratory indexes in the blank control group were insignificant before and after treatment ( P>0.05). The results of inter-group comparison after treatment showed that Zhuang needle-cupping therapy group had better effect on improving S-IgE, LT, IFN-γand Th1/Th2 than cetirizine group and Flixonase group (P<0.05). (3) During the trial, no adverse reaction was found. Conclusion Zhuang needle-cupping therapy exerts certain therapeutic effect for AR, and the mechanism may be related with the inhibition of S-IgE, LT, IL-9 mRNA and IL-17 expression, and with the regulation of Th1/Th2 imbalance by decreasing TH2 cytokine level and increasing Th1 cytokine level.

Objective To evaluate the effect of remifentanil on cell apoptosis during renal ischemia-reperfusion (I/R) in rats.Methods Seventy-five male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 3 groups (n =25 each):sham operation group (group S),I/R group,and remifentanil group (group R).Renal ischemia was induced by occlusion of the bilateral renal arteries for 45 min followed by reperfusion in groups I/R and R.Remifentanil was infused at 1.0 μg· kg-1 · min-1 via the caudal vein starting from 15 min before ischemia until 30 min of reperfusion in group R,while the equal volume of normal saline was given instead of remifentanil in groups S and I/R.At 15 min before ischemia (T0) and 3,6,12,24 h of reperfusion (T1-4),5rats were anesthetized and sacrificed,and renal specimens were obtained to detect the apoptotic rate and expression of Bax and Bcl-2 protein (by flow cytometry) and mRNA (by RT-PCR).The ratios between Bcl-2/Bax protein and mRNA expression were calculated.The pathological changes of renal tubules were scored.Results Compared with group S,the pathological scores and apoptotic rate were significantly increased at T1-4,and ratios between Bcl-2/Bax protein and mRNA expression were increased at T1,2,while decreased at T3,4 in groups R and I/R (P ＜0.01).Compared with group I/R,the pathological scores and apoptotic rate were significantly decreased at T1-4,while the ratios between Bcl-2/Bax protein and mRNA expression were increased in group R (P ＜ 0.05 or 0.01).Compared with the baseline value at T0,the pathological scores and apoptotic rates were significantly increased at T1 4,and the ratios of Bcl-2/Bax protein and mRNA expression were increased at T1,2,while decreased at T3,4 in groups R and I/R (P ＜ 0.01).Conclusion Regulation of Bcl-2/Bax expression and inhibition of cell apoptosis in renal tissues are involved in the mechanism by which remifentanil reduces renal I/R injury in rats.

The response of glueagon to the change of glucose and its relation to blood pressure in 71 eidely patients with type 2 diabetes was investigated. The results showed that the postprandial increment of glucagon in the group of patients with postprandial 2h plasma glucose increment<2.5 mmol/L was significantly higher than that in the group with plasma glucose inerement≥ 2.5 mmoi/L (P<0. 05). The postprandial increment of glucagon in patients with normal blood pressure was significantly higher than that in patients with hypertension (P<0.05). The results suggest that the decreased response of glucagon to the change in plasma glucose in elderly patients with type 2 diabetes is related to increased blood glucose and high blood pressure.

Objective To explore the risk factors of sepsis complicated with hepatic insufficiency in elder patients.Methods With retrospective case-control study method,according to whether or not complicated with hepatic insufficiency,a total of 384 elder sepsis patients were divided into case group (91 patients) and control group(293 patients),then single factor analysis and multiple factors Logistic regression methods were used to screen the risk factors.Results Single factor analysis identified 6 kinds of significant variables,including age(P =0.000),history of alcohol(P =0.006),chronic diseases(P =0.001),arterial blood lactate level (P =0.035),mechanical ventilation (P =0.009) and acute physiology and chronic health evaluation Ⅲ score (APACHE-Ⅲ) scores(P =0.004).Multiple factors Logistic regression analysis showed that age,history of alcohol,chronic diseases,arterial blood lactate level,mechanical ventilation,APACHE-Ⅲ scores were correlated with sepsis complicated hepatic insuffciency in elder patients (P ＜ 0.01 or ＜ 0.05).Conclusion The risk factors which closely relate to sepsis complicated with hepatic insufficiency in elder patients are age,history of alcohol,chronic diseases,arterial blood lactate level,mechanical ventilation,APACHE-Ⅲ scores.
