Objective This paper is to explore the relationship between the placement of the bone oscillator and bone-conducted thresholds to ASSR stimuli in adults with normal hearing and to investigate the amplitude and the threshold differences to bone-conducted auditory steady-state responses (BC-ASSR) stimuli between single - and multiple-stimulus conditions. Methods Two groups of subjects were selected with 0. 5, 1, 2 and 4 kHz brief tones repeated at the rate of 77, 87, 93 and 101 Hz using a B-71 bone oscillator either in single- or multiple ted no significant differences between mastoid and behind-the-ear placements. The mean and standard deviations of bone-conducted behavioral thresholds to ASSR stimuli at 0.5, 1, 2 and 4 kHz were 62.6±4.8,47.1±4.8,46.8cant difference between the two conditions while the mean and standard deviations of BC-ASSR thresholds at 0.5, 1, 2 and 4 kHz were 96.7±9.7,70.3±11.6,60.6±7.4,52.8±7.2 dB re: 1μN (ppe), respectively. Conclusion The behavioral bone-conducted thresholds to ASSR stimuli with mastoid and behind-the-ear placemen yielded no significant differences. When the stimuli intensity was 50 dB nHL, the amplitudes in single-stimulus condition were significantly higher than those to multiple-stimulus condition. There were no significant differences for BC-ASSR thresholds between single- and multiple-stimulus condition.

The microRNA let-7 family,functioning as a tumor suppressor,has emerged as a regulator of stem cell differentiation and tumor repression.The RNA-binding protein lin28 is a stem cell pluripotency factor,which contributes to the maintenance of stem cell characteristics and promoting cell malignant transformation.lin28 can block the maturity of let-7 by combining with the precursors of let-7 family miRNAs,which is itself able to repress lin28 by binding to the 3'-UTR of lin28 transcripts,thus forming a feedback loop.The double-negative feedback loop comprising lin28 and let-7 is involved in several biological processes such as differentiation of stem cell,tumorigenesis,invasion and metastasis,drug resistance and relapse,which couldbe a potential target for cancer therapy.

MicroRNAs (miRNAs) are a class of highly conserved small noncoding single stranded RNAs.They participate in the regulation of target genes through the degradation of mRNA and/or inhibition of translation.As the most abundant miRNAs in the central nervous system,miRNA-124 (miR-124) has been widely given attention in recent years.The recent research suggests that miR-124 is closely associated with ischemic cerebral injury,but its specific regulation mechanism remains unclear.This article reviews the roles of miR-124 in ischemic cerebral injury.

Objective To investigate the effect of the serum ferritin,folic acid and its clinical efficacy by Chinese angelica Astragalus decoction combined with Iron Sucrose Injection in the treatment of the anemia patients with chronic renal failure.Methods 66 anemia patients with chronic renal failure were selected and randomly divided into the control group and the experiment group with 33 cases in each group.The control group were treated by Venofer and the experiment group were treated on the base of the control group with Chinese angelica and Astragalus Decoction.The clinical curative effect before and after treatment,serum ferritin,folic acid(SF),serum creatinine(Scr),urea nitrogen(BUN),creatinine clearance rate(Ccr),blood uric acid(UA),cholesterol(TC),total cholesterol(TG),high density lipoprotein(HDL-C)were compared after 6 months of treatment and the adverse reaction conditions was compared during the treatment between two groups.Results The effective rate of treatment in the control group was 69.70％lower than that in the observation group,the effective rate was 90.91％,with statistical significance(P<0.05).Compared with the control group,the SF and folic acid levels were lower,the Scr and BUN levels were lower,the Ccr and UA levels were higher,the TC and TG levelswere lower,the HDL-C level was higher,with statistical significance(P<0.05).Conclusion Angelica Astragalus decoction combined with Iron Sucrose Injection in the treatment of chronic renal failure patients with anemia effect is significant,can effectively reduce the level of serum ferritin and folic acid,the clinical effect is better.

Objective To observe the real-time and short-term therapeutic efficacies of fire-needle acupuncture and warm needling in treating cervical vertigo due to upward disturbance of phlegm-turbidity, and compare the two treatment methods. Method Eighty-four patients with cervical vertigo due to upward disturbance of phlegm-turbidity were randomized into a fire-needle acupuncture group and a warm needling group, 42 cases in each group. The two groups received treatment once a day, respectively for 10 sessions. The symptoms, functions and total score were evaluated by adopting the modified Cervical Vertigo Symptoms and Functions Assessment Scale before the second treatment session and after 10 treatment sessions; the therapeutic efficacy was evaluated based on the traditional Chinese medicine symptoms scale. Result The scores after 10 treatment sessions were significantly different from that before treatment in the two groups (P<0.05);before the 2nd treatment session, the improvements of the symptoms and total scores in the fire-needle acupuncture group were more significant than that in the warm needling group (P<0.05);after 10 sessions, there were significant differences in comparing the symptoms, functions and total scores between the two groups (P<0.05);the clinical control rate was 26.2%and total effective rate was 95.2%in the fire-needle acupuncture group, versus 9.5%and 90.5%in the warm needling group, and there was a significant difference in comparing the therapeutic efficacy between the two groups. Conclusion Fire-needle acupuncture and warm needling both are effective in treating cervical vertigo due to upward disturbance of phlegm-turbidity, while fire-needle acupuncture can improve the vertigo symptoms in a real-time manner, and its short-term therapeutic efficacy is also superior to that of warm needling.

Objective To evaluate the efficacy of telbivudine in HBeAg-positive chronic hepatitis B (CHB) patients by comparing the efficacy of initial telbivudine therapy in treatment-naive patients with sequential telbivudine therapy in patients with poor response to adefovir.Methods A total of 90 HBeAg-positive CHB patients were assigned to receive sequential telbivudine therapy following poor response to adefovir dipivoxil (n=45),or initial telbivudine therapy in antiviral treatment-naive patients (n=45).All patients were treated with telbivudine 600 mg daily for 104 weeks.The efficacy was evaluated in terms of liver function tests,serum HBV markers,HBV DNA and antiviral drug resistance.Results Telbivudine showed good overall efficacy after treatment for 104 weeks in terms of alanine aminotransferase normalization rate (91.1％),HBV DNA negative conversion rate (80.0％),HBeAg loss rate (57.8％),and HBeAg/HBeAb seroconversion rate (30.0％).The HBV DNA negative conversion rate in initial treatment group was significantly higher than that in sequential treatment group (P＜0.05).However,among the patients with early response,the efficacy did not show significant difference between groups (P＞0.05).The patients with early response showed significantly better efficacy than those without early response,in terms of higher HBV DNA negative conversion rate,higher HBeAg loss rate and HBeAg/ HBeAb seroconversion rate (P＜0.000 1 or P＜0.05),but lower virological breakthrough rate (P＜0.05).Conclusions Telbivudine has shown reliable efficacy in CHB patients.Initial telbivudine therapy is better than sequential therapy in CHB patients with poor response to adefovir.However,for patients with early response to telbivudine,no statistical difference is found between initial and sequential therapy in long-term treatment efficacy (104 weeks).The patients receiving sequential telbivudine therapy should be monitored closely for early antiviral response to optimize treatment.

AIM: To evaluate the clinical feature of 9 patients harboring mitochondrial DNA ( mtDNA ) G11778A mutation with Leber hereditary optic neuropathy ( LHON) .
●METHODS: Nine LHON patients were enrolled and followed- up between 2012 to 2015 in Shenzhen Eye Hospital, clinical data were collected and analyzed.
●RESULTS: Six cases had maternal inheritance history ( 67%) . Three were sporadic cases. The patients aged from 9 to 43 years old, with average age of (22. 00±9. 42) years. Simultaneous onset with both eyes was in 5 cases (56%). Successively onset was in other 4 cases (44%). The ratio between male and female was 2:1. In the last follow-up, the visual acuity was finger counted in 2 eyes (11%), 0. 01-0. 1 in 12 eyes (67%), 0. 12-0. 4 in 2 eyes (11%),≥0. 4 in 2 eyes (11%). All patients had pale disc and clear boundary. ln the Humphrey visual field examination, 10 eyes had typically cecocentral or paracentral scotoma, 8 eyes had diffuse visual field defect.
●CONCLUSION: ln the 9 LHON patients with mtDNA G11778A mutation, simultaneous onset cases were more than successively onset cases within 1y cases. In most cases, LHON patients kept stable visual acuity. Rare cases had a raise in visual acuity within 1y. Majority patients had typically cecocentral or paracentral visual field scotoma. In the last stage of LHON, visual field present diffused defect. The secondary affected eye was similar performed defect as the former one.

Objective To explore the etiology, pathogenesis, syndrome differentiation and treatment for dengue fever according to the theory of traditional Chinese medicine ( TCM) . Methods A retrospective case analysis was carried out in 257 dengue fever patients admitted in 2013 by Guangdong Provincial Hospital of Traditional Chinese Medicine. The clinical data of pathogenic features, TCM symptoms and signs, and therapeutic regimen were collected and analyzed. Results Six commonly-seen TCM syndrome patterns for dengue fever were classified into disease involving both defensive system and Qi system, excessive heat in defensive system, summer-heat and dampness stagnating the middle-jiao or attacking the exterior, excessive heat in both Qi system and blood system, pathogenic factors lodging between diaphragm and pleura, and mixture of blood stasis and toxicity, and the corresponding prescriptions were Yinqiao Powder, Chaige Jieji Decoction, Xinjia Xiangru Decoction, Qingwen Baidu Decoction, Dayuan Decoction, Xijiao Dihuang Decoction, respectively. Conclusion The TCM syndrome patterns of dengue fever in Guangzhou area are characterized as excessive heat in Qi system, complicated with nutrient and blood system syndrome, and mostly are blended with dampness. Correspondingly, the therapeutic principles should be clearing heat and removing toxicity in Qi system with cold-cool herbs, and assisting with cooling blood to clear heat in Qi system and removing dampness.

Objective To observe the clinical efficacy of pricking anti-Ashi points with fire needles in treating acute lumbar sprain.Method Seventy-six patients with acute lumbar sprain were randomized into a treatment group and a control group, 38 cases in each group. The treatment group was intervened by pricking anti-Ashi points with fire needles, while the control group was by warm needling. The Visual Analogue Scale (VAS) and Roland-Morris Dysfunction Questionnaire (RMDQ) were adopted to evaluate lumbar pain and dysfunction after 1-day and 5-day treatment, and the clinical efficacies were compared between the two groups.Result Respectively after the first treatment session and 5 treatment sessions, the VAS and RMDQ scores were significantly changed in both groups (P<0.01). Respectively after the first treatment session and 5 treatment sessions, the VAS and RMDQ scores in the treatment group were significantly different from that in the control group (P<0.05). The total effective rate and recovery rate were respectively 94.7% and 63.2% in the treatment group, versus 86.8% and 42.1% in the control group, and the differences were statistically significant (P<0.01).Conclusion Pricking anti-Ashi points with fire needles is an effective method in treating acute lumbar sprain, and it can produce a significant real-time analgesic effect.
