Objective To analyze the therapeutic effect ofShengji-Yuhong ointment in the treatment of patients with pressure ulcer.Methods 86 patients of pressure ulcer were randomly divided into a control group and an observation group, with 43 cases in each. After debridement, the wound was covered with vaseline gauze in the control group, whileShengji-Yuhong ointment in the treatment group. 10 days constituted 1 course of treatment, and both groups were treated for 3 courses. The blood supply of the whole blood viscosity, plasma viscosity, erythrocyte aggregation index detection; white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and C reactive protein (CRP) were observed in order to observe the control condition of the patients with wound infection.Results The total effective rate was 95.3% (41/43) and 74.4% (32/43) in the observation group and control group respectively, with significant difference between two groups (χ2=5.800,P=0.016). After treatment, the whole blood viscosity (high-shea) (4.06 ± 1.38 mPa?svs. 4.74 ± 1.62 mPa?s,t=2.095), the whole blood viscosity (medium-shea) (3.71 ± 1.22 mPa?svs. 4.34 ± 1.41 mPa?s,t =2.216), blood reduction viscosity (1.13 ± 0.22 mPa?svs.1.44 ± 0.51 mPa?s,t=3.660), the whole blood viscosity (medium-shea) (4.16 ± 0.48 mPa?svs. 4.51 ± 0.89 mPa?s,t=2.270) obviously compared with group before treatment decreased (P<0.05). The patients in the observation group in the whole blood viscosity (medium-shea) (3.71 ± 1.22 mPa?svs. 4.16 ± 0.48 mPa?s,t=2.251), and blood reduction viscosity (1.13 ± 0.22 mPa?svs. 1.32 + 0.31 mPa?s,t=3.278) in the observation group were  obvious better than the control group (P<0.05). After the treatment the WBC, CRP, ESR in the observation group were decreased significantly than the control group (t=5.947, 7.198, 12.064,P<0.01).ConclusionShengji-Yuhong ointment can effectively control the PU infection in the wound, improve wound tissue under the blood circulation, and promote wound healing.

OBJECTIVE: To investigate the efficacy of combined medical treatment on auditory neuropathy spectrum disorder and the effect of related factors on the prognosis. METHOD: Eleven cases (22 ears) diagnosed as auditory neuropathy spectrum disorder using multiple criteria including pure tone auditory threshold, impedance audiometry, acoustic reflexes, distortion products otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were subjected to combined medical treatment . Eleven auditory neuropathy spectrum disorder patients diagnosed during the corresponding period but refused treatment were selected as control group. The change of pure tone auditory threshold and speech discrimination score after treatment or follow-up were evaluated for both 2 groups, and the relationship between the patients' gender, age, accompanying symptoms and curative effect were also analyzed. Data were analyzed by SPSS 19.0 statistical software using pared-sample t-test, independent-sample test and Pearson's chi-square test. RESULT: The effective rate of combined medical therapy was 59.09% (13/22) in the therapy group. PTA levels before and after-treatment were (53.92 +/- 18.86) dB HL and (47.44 +/- 14.98) dB HL respectively in 22 ears with the combined medical therapy, the improvement of which showed statistically significance (t = 5.20, P < 0.05). No obvious hearing change was noted in the 11 patients who refused therapy (P > 0.05). Speech discrimination score before and after-treatment were (29.20 +/- 25.80)% and (41.60 +/- 22.90)% respectively for the treatment group. The average improvement of speech discrimination score was (12.40 +/- 13.80)% with statistically significant difference (t = 4.02, P < 0.05). Patients accompanied with tinnitus had relatively poorer effect compared with individuals without tinnitus (t = -3.85, P < 0.05). Age is negatively correlated with the prognosis (r = -6.72, P < 0.05). Gender had no effect on the prognosis (P > 0.05). CONCLUSION The combined medical therapy with glucocorticoids helps improving the pure tone auditory threshold and speech discrimination score of auditory neuropathy spectrum disorder. In light of our findings we support the combined medical therapy as an option for patients with auditory neuropathy spectrum disorder.
