ABSTRACT
Objective@#To investigate the correlation between age-related hearing loss and cognitive impairment.@*Methods@#201 elderly patients, who were admitted to the Department of Otorhinolaryngology of Peking University People′s Hospital from March 1, 2017 to March 31, 2017, were evaluated with hearing screening and the Montreal Cognitive Assessment Scale. Among them, 101 were female and 100 were male, aged 60-90 years old. Taking the cognitive level as the dependent variable, and taking the age, sex, education, occupation, marital status, residence, and average hearing loss (average hearing threshold of 500, 1 000, 2 000, and 4 000 Hz), as well as the length of conscious hearing loss as the independent variables, the single factor analysis and multivariate linear regression analysis were used to screen the main factors affecting the cognitive level of the elderly.@*Results@#Of the 201 elderly patients, 39 had normal hearing, 65 had mild hearing loss, 80 had moderate hearing loss, 16 had severe hearing loss, and 1 had profound hearing loss. The average degree of hearing loss was the influencing factor of cognitive impairment, and it mainly affected the directional force and abstract ability in the cognitive domains (P<0.05); The age, self-reported hearing loss, years of education, marital status, past ear diseases, and hypertension were relatively independent factors that affected the cognitive level(P<0.05).@*Conclusions@#Age-related hearing loss is the risk factor for the cognitive impairment, especially for abstraction and orientation, in the elderly. The self-reported hearing loss is an independent risk factor for cognitive impairment.
ABSTRACT
Objective:To explore the clinical effect of intravenous immunoglobulin combined with conventional therapy in the treatment of severe pneumonia in infants and children.Methods:Selected the January 2015 to April 2016 in our hospital for treatment of 88 cases of children with severe pneumonia were retrospectively analyzed,which 47 cases by routine treatment plus intravenous immunoglobulin protein (treatment group),41 cases of children only take routine therapy (control group),with a course of 2 weeks.Results:The symptoms of fever,dyspnea,cough,wheezing,pulmonary rales were improved faster in the treatment group than the control group (P＜0.05);after 2 weeks of treatment,IgG levels were significantly higher in the treatment group than the control group(P＜0.05);after 2 weeks of treatment,the serum IL-6 and TNF-α levels were significantly lower in the treatment group than the control group(P＜ 0.05);after 1 week of treatment,57.45％ of patients was cured in the treatment groups while only 34.15％ patients in the control group (P＜0.05).Conclusion:Intravenous immunoglobulin combined with conventional therapy in the treatment of infants with severe pneumonia can significantly improve the theraputic effect and enhance blood immunoglobulin levels.
ABSTRACT
OBJECTIVE:To observe clinical efficacy and safety of naloxone hydrochloride combined with Danshen injection in the treatment of neonatal hypoxic ischemic encephalopathy(HIE). METHODS:104 patients with HIE were randomly divided into observation group and control group with 52 cases in each group. The control group was treated with Naloxone hydrochloride injec-tion 0.02 mg/kg,ivgtt,qd and conventional symptomatic treatment;while observation group was additionally treated with Danshen injection 4-6 ml+10% Glucose injection 20 ml,ivgtt,qd,on the basis of the control group. Treatment course of 2 groups lasted for 7 d. Clinical efficacy,symptom and sign recovery of 2 groups were compared,as well as levels of serum MMP-9,IL-6 and TNF-α,cerebral hemodynamic parameters and ADR. RESULTS:There was no statistical significance in MMP-9,IL-6,TNF-α and cerebral hemodynamic parameters before treatment(P>0.05). The total effective rate of observation group(92.31%)was signifi-cantly higher than that of control group (75.00%);after treatment,the recovery time of consciousness disturbance,primitive re-flex and muscle tension in the observation group were shorter than those in the control group;the levels of serum MMP-9,IL-6 and TNF-α in observation group were significantly lower than those in control group;peak systolic flow velocity(PSFV),end-dia-stolic flow velocity (EDTV) were higher in the observation group than in the control group,with statistical significance (P0.05). No ADR was ob-served in 2 groups. CONCLUSIONS:Naloxone hydrochloride combined with Danshen injection can significantly promote HIE and signs recovery,reduce the levels of serum MMP-9,IL-6 and TNF-α,and improve hemodynamic parameters with good safety.
ABSTRACT
BACKGROUND:Transplanted neural stem cel s can survive, proliferate and differentiate into neurons and/or glial cel s in the host, thereby promoting partial function recovery in the host. OBJECTIVE:To study the therapeutic effects of neural stem cel transplantation on cerebral palsy rats. METHODS:Twenty-four rats were randomly divided into three groups:control group, model group and transplantation group. Animal models of cerebral palsy were made in the latter two groups. One week after modeling, rats in the transplantation group were injected 1 mL stem cel suspension (1×105) via the jugular vein, and rats in the control and model group were given the same volume of normal saline. Toe distance, step length and elevated body swing test in rats were detected, and histopathological changes in the rat brain were observed 3 weeks after transplantation. RESULTS AND CONCLUSION:In the model group, the toe distance and step length of the front left palm were significantly lower than those of the front right palm (P body, but rats in the other two groups exhibited symmetric swing of the body (P<0.05). Additional y, the ratio of right to left hemispheric areas was significantly higher in the transplantation and control groups compared with the model group (P<0.05). In conclusion, neural stem cel transplantation via the jugular vein can improve brain function and restore motor function in rats with cerebral palsy.
