Objective To observe teletherapy and local hyperthermia effects on VX2 carcinoma rabbits'cytokines and curative effect. Methods 60 male white health rabbits were selected, and divided them into three group. The group of teletherapy were 20. The group of local hyperthermia were 20. So were the group of comparison. Their tumors' changes, rates of death and changes of IL-2, IL-6, IL-8, TNF, IGF, CA-50 before and after VX2 carcinoma replanted and those treated after one, three, four weeks were observed. Results The diameters of tumors and rates of death from large to small in turn was comparison's group, hyperthermia's group and teletherapy's group. After VX2 carcinoma replanted IL-2, IL-8 were low but IL-6, TNF, IGF, CA-50 were high. After being treated one, three or four weeks, IL-2, IL-8 were getting lower and lower but there was significant difference between teletherapy's group with other group in IL-2 and IL-8(P

Objective:To explore the curative effect and adverse reactions of cisplatin combined with rIL-2 on malignant pleural effusion. Methods:Totally 60 cases of patients with malignant pleural effusion were randomly divided into the observation group ( 30 cases) and the control group (30 cases). In the observation group, 30 cases were given intrapleural injection of cisplatin and rIL-2 af-ter the pleural effusions were drained, and in the control group, the patients received intrapleural injection of cisplatin. Both of the two groups were observed of tumor response and drug adverse reactions, compared the quelity of life and immune function indicators before and after treatment. Results:The response rate in the observation group was 83. 3%, which was significantly higher than that in the control group (56. 7%) (P<0. 05). The improvement of Karnofsky score in the observation group was 86. 7%, which was also nota-bly higher than that in the control group(63. 3%) (P<0. 05). After the treatment, CD4 level and CD4/CD8 were significantly in-creased in the observation group(P<0. 05), while those in the control group were notably decreased (P<0. 05), and the difference was statistically significant (P<0. 05). The incidence of adverse reactions shew no significant difference between the two groups (P>0. 05). Conclusion:Cisplatin combined with rIL-2 shows confirmed effects in the patients with malignant pleural effusion.

OBJECTIVE To study the effect of frequency difference and intensity difference on mismatch negativity (MMN) change in normal persons. Emphatically to observe the effect on the latency and amplitude of normal people's MMN, as well as the threshold of the acoustic difference which may induce the MMN. METHODS Twenty-four adults were included in this study. Their thresholds of pure tone audiometry were within 20dBHL. The MMN were measured by using the Smart EP ( ear potentiometer provided by the company of Intelligent Hearing) and the rule of the change by the difference of frequency and intensity to the latency and amplitude of normal people’s MMN were studied. RESULTS Along with the decreasing of the difference of the frequency, the MMN latency prolonged gradually. The amplitude of the MMN decreased gradually as the decreasing of the intensity difference. CONCLUSION A stable MMN graph is an important indicator of objective physiological test with hearing distinguish.

Objective To investigate precision error between Varian auri-point localization system and Tosplane digital-bed localization system. Methods Varian Eclipse localization method and Topslane localization method were used separately to locate one target area for one same patient. Then deviations on the tumor center coordinate were measured under the simu- lation localization machine. Results Under two localization methods, the length error: 1.7mm ?0.3mm; the width error: 0.5mm?0.4mm; the altitude error: 1.2mm?0.4mm. Conclusion The curative effect of radiotherapy would be improved by applying the Topslane localization bed to the Varian Eclipse plan system.

OBJECTIVE To report a case of AIDS associated with penicilliosis marneffei and discriminate the morphology in bone marrow examination and cultural characteristic of Histoplasma capsulatum and Leishmania donovani.METHODS The three pathogens in bone marrow morphology and cultural characteristic were studied.RESULTS AIDS patient was often infected with P.marneffei,but we could differentiated easily from other pathogens because of its breeding by splitting up and the characteristis structure in bone marrow examination.CONCLUSIONS Isolation of the P.marneffei is the golden diagnosis standard,and the examination of bone marrow is important to diagnose P.marneffei infection.

Background Pluripotent stem cell-derived retinal pigment epithelial (RPE) cells holds great promise for the treatment of age-related macular degeneration (AMD) and retinitis pigmentosa (RP),but the poor induction efficiency and the according high cost of RPE differentiation hindere its clinical applications.Curcumin is proved to have a promoting effect on the induced differentiation of embryonic stem cells (ESCs).However,the mechanism of curcumin on differentiation of human ESCs into RPE-like cells remains unclear.Objective This study aimed to explore the underlying molecular mechanism of curcumin on directed differentiation of human ESCs into RPE-like cells.Methods Human ESCs strains were cultured in the Matrigel-coated 6-well plate with mTeSRTM 1 medium until over-confluence,and basic fibroblast growth factor was withdrawn there after to induce automatic differentiation.Curcumin at the final concentration 1 μmol/L was added in the first day of differentiation for 24 hours,and the cells without curcumin in the medium served as the control group.Total RNA and protein were extracted at 3 weeks and 5 weeks after induction.RT-PCR,Western blot and immunofluorescence were performed to examine the expressions of the biomarks of stem cells and RPE cells as well as Wnt/β-catenin signaling pathway components.The endocytosis of polystyrene microsphere by induced RPE (iRPE) cells was investigated to verify their function of phagocytosis which features RPE cells.Results Pigmented cells were found from 3 weeks through 5 weeks after induction in the curcumin group,but only less pigmented cells were seen in the fifth week after induction in the control group.In the third and fifth week after induction,the relative expression levels of NANOG mRNA in the iRPE cells were significantly lower than those in the control group (t =13.086,P =0.022;t =34.186,P =0.004),and the relative expression levels of Pax6,RX,CRALBP and RPE65 mRNA were higher in the curcumin group than those of the control group (all at P＜0.01).Western blot assay showed that the expressing bands for CRALBP,RPE65 and MITF enhanced in iRPE cells with a similar appearance in human RPE cells.However,these expressions were all absent in human ESCs.Immunofluorescence staining showed the positive expressions of Pax6,MITF and ZO-1 in cytoplasm of iRPE cells in the curcumin group with a purified efficacy 100％.The fluorescence dye-doped polystyrene microspheres in cytoplasm were obvious in the iRPE cells like positive controls,but the polystyrene microsphere was absent in the negative controls.From 3 weeks through 5 weeks after induced,the relative expression levels of Lef1,MYC and TCF7 mRNA (the dwnstream target genes of Wnt signaling pathway),FZD3 mRNA (Wnt receptor),Wnt2B mRNA (Wnt ligand) and Wnt7B mRNA were significantly reduced in the curcumin group compared with the control group (all at P＜0.01).Conclusions Curcumin promotes the differentiation of human ESCs into RPE-like cells by stimulating the activation of Wnt signaling pathway,and therefore accelerate the differentiation and mature of iRPE cells.

OBJECTIVE: To investigate the characteristics of tinnitus in patients with auditory neuropathy spec- trum disorder (ANSD). METHOD: This study recruited 14 ANSD patients with tinnitus. All the ANSD patients un- derwent detailed history taking, audiological examinations and assessments of tinnitus. This study analyzed the correlation of tinnitus status and hearing loss, and discussed the effects of sex, age, and the course of disease on tinnitus in ANSD patients. RESULT: (1) In the ANSD patients, tinnitus often occurred in 3 years after the onset of hearing loss; (2) Tinnitus was highly prevalent in ANSD patients, and the severity of tinnitus was mostly from mild to moderate; (3) There was no obvious correlation between the subjective grading of tinnitus and hearing loss de- gree, and the impact of curve patterns of hearing loss on the level of tinnitus need much more evidence-based proof; (4) Along with the course extension, the impact of tinnitus on the quality of life was much more obvious; (5) Some risk factors such as noise exposure could be the reasons of aggravating the degree of tinnitus. CONCLUSION Tinnitus in ANSD patients has its unique clinical features. The study of Tinnitus in ANSD patients can provide clinical basis for further research in ANSD.

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.
