Chinese Journal of Postgraduates of Medicine 2011;34(18):19-21
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.

Shanghai Journal of Acupuncture and Moxibustion 2015;(6):537-539
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.

Chinese Journal of Rheumatology 2009;13(6):-
ObjectiveTo investigate the effect of bone marrow-derived mesenchymal stem cells (MSCs) on collagen-induced arthritis(CIA) and the possible mechanisms. MethodsMSCs from C57BL/6 mice bone marrow were isolated and expanded. Three DBA-I mice were as normal control group (Sodium Chloride injected on day 0 and 21) after primary immunization. After the bovine collagen Ⅱ induced-CIA models were established, fifteen male mice were randomly divided into 3 groups according to treatment regi-mens: CIA control group(0.2 ml Sodium Chloride injected through caudal vein on day 0 and 21), prevention group(1×10+6 cells MSC on day 0) and treatment group. (1×10+6 cells MSC on day 21 after primary immun-ization). The observed parameters included arthritis index (Al), articular pathology changes, levels of serum TNF-α, IL-1β detected hy ELISA. In addition, the percentage of CD4+CD25+Foxp3+Treg cells(Tregs) in CD4+ T cells of spleen or lymphoid node from mice were also analyzed by flow cytometry(FCM). Results①The Al and articular pathological score of the prevention group and treatment group were lower than the CIA control group(P<0.05). ②The levels of serum TNF-α and IL-1β of normal control, prevention group and treatment group were significantly decreased compared with CIA control group(P<0.05), and positively correlated with Al or articular pathological score (P<0.05). ③The percentage of Tregs from spleen and lymph nodes was significantly increased in MSCs treated mice(P<0.05). Conclusion MSCs transplantation is effective for CIA and suppression of TNF-α, IL-1β and up-regulation of Tregs by MSCs may be the possible mechanism in CIA.
