Objective To investigate the relevant factors on the prognosis of sudden deafness. Method The clinical data of 133 patients (148 ears) with sudden deafness were analyzed retrospectively. Results Through systemic treatment, 25 cases got recovery, 18 cases were excellence and 39 cases were effective, the total effective rate was 61.7%(82/133). Univariate analysis showed that the factors related to the prognosis of sudden deafness were age, the time from onset to treatment, deafness classification,accompanied by vertigo or not and the duration of treatment. Patients with the age lower than 60, the earlier the time from onset to treatment, the lighter the deafness classification, not accompanied by vertigo and the longer duration of treatment got a better efficacy. Logistic regression analysis showed that the independent factors related to the prognosis of sudden deafness were the time from onset to treatment and deafness classification. Conclusion The etiology of sudden deafness is still unclear, the time from onset to treatment interval and the degree of hearing loss are the main factors affecting the prognosis of it, in clinic, it should be paid attention and took a early diagnosis and early treated so as to get good efficacy.

OBJECTIVE:To discuss the effects of Kangshuling gel on wound treatment and infection prevention inⅡdegree burns. METHODS:60 patients with Ⅱ degree burns were randomized intro observation group and control group,with 30 cases in each group. Based on routine treatment (cleaning,disinfection,necrotic tissue removal,antibiotics use),observation group was given Kangshuling gel,and control group was treated with sulfadiazine. The average healing rate,healing time,surgical dressing exudate,inflammatory reaction around wound,the times of dressing change and inner layer gauze change,and wound infection rate were observed in 2 groups,and satisfaction survey was conducted in 2 groups. RESULTS:On 14th and 18th day after treat-ment,average rate of wound healing in observation group was significantly higher than in control group;the time of wound heal-ing was significantly shorter than control group,with statistical significance(P<0.05). Within 2 weeks after treatment,the number of gauze layer wetted by surgical dressing in observation group was significantly less than in control group,and case number of in-flammatory reaction around wound was significantly less than control,with statistical significance(P<0.05). The times of dressing change and inner layer gauze change in observation group was significantly less than in control group,and the rate of wound infec-tion was significantly less than control group,with statistical significance(P<0.05);the satisfaction of observation group was bet-ter than that of control group,with statistical significance(P<0.05). CONCLUSIONS:Kangshuling gel in the treatment of Ⅱ de-gree burns can effectively prevent and treat wound infection,reduce the rate of wound infection and the times of dressing change, shorten the time of wound healing and improve the rate of wound healing so,high satisfaction degree is obtained.

Objective To compare the clinical efficacy and onset time between Tiao Ren An Shen (regulating Conception Vessel and soothing mind) needling method and conventional acupoint selection for peri-menopausal depression, for providing theoretical evidence for the application of Tiao Ren An Shen needling method. Method Sixty patients with peri-menopausal depression aged 45~55 years were randomized into two groups after admission to hospital. In addition to oral administration of Fluoxetine, one group was intervened by Tiao Ren An Shen needling method (treatment group, n=30), and the other group was by conventional acuppoint selection (control group, n=30). Before treatment, and at 2nd, 4th, and 6th week after treatment, Hamilton Depression Scale (HAMD) was investigated, Kupperman index and traditional Chinese medicine (TCM) syndrome score were evaluated before and after intervention. The therapeutic efficacy was estimated at the end of the 6th week. Result After intervention, the HAMD and TCM syndrome score were significantly improved in both groups (P<0.05); Kupperman score was markedly improved in the treatment group (P<0.05), while the score was not significantly changed in the control group (P>0.05). Compared to the control group, the improvements of depression degree and peri-menopausal symptoms were more significant in the treatment group (P<0.05). The total effective rate was 93.3% in the treatment group versus 70.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Compared to conventional acupoint selection, Tiao Ren An Shen method can produce a more efficient effect and a higher long-term efficacy, not only improving the emotional state and easing depression, but also releasing vegetative nerve functional disturbance. As it can improve the TCM symptoms, treating both causes and manifestations, promoting the quality of life of peri-menopausal patients, this method is an effective approach.
