35u/ml as positive limit, the sensitivity of CA125 for diagnosis of lung cancer is 53.6%. There was no significant difference between stage Ⅰ,Ⅱ lung cancer and benign, healthy groups, but the level of serum CA125 of stageⅢ?Ⅳ was higher than control groups. Thirty eight of forty lung cancer patients with higher CA125 level dropped to normal after therapy. Conclusions:Serum CA125 has high diagnosis value in lung cancer. It can be a vital index in lung cancer staging and prognosis.

Objective To study the clinical importance of TCM used in solidified therapy of colorectal cancer after radical resection. Method Prospective cohort study was applied to the trial, 84 cases in Xiyuan Hospital were selected to compare with 78 cases in western medicine hospital in the same time. The rates of relapse-metastasis and disease free survival of two groups were observed. Nine possible factors influencing disease-free survival were selected to analyze with COX regression model. Results 1-year, 2-year and 3-year relapse-metastasis rate of the teatment group were 0, 4.08% and 20% respectively, those were 5.12%, 22.91% and 36.11% in the control group. 1-year, 2-year and 3-year disease-free survival rate of teatment group were 100%, 95.91% and 80%, those were 94.87%, 77.08% and 63.88% in the control group. The main prognostic factors were lymph nodes metastasis and therapy. Conclusion TCM used in postoperative colorectal cancer could prevent relapse and metastasis.

Background The enhance of differentiation of orbital preadipocyte is a main factor for pathogenesis of thyroid associated ophthalmopathy(TAO).Experiment has proved that orbital preadipocyte can differentiate into mature adipocyte expressing resistin,and resistin is a adipocyte factor with biological activity.Objective The present study is to investigate the effects of recombinant human resistin on differentiation of orbital preadipocytes derived from TAO patients orbital tissues.Methods Orbital adipose tissue was obtained from 10 eyes with TAO during the orbital decompression surgery.Orbital adipose tissue of the normal group was obtained from 5 removed eyes during the surgery due to different reasons.Preadipocytes were isolated and cultured using expand culture method.The 2-5 generations of preadipocytes were identified by oil red O staining under the light microscope.0,10,25,50,100ng/mL of recombinant human resistin were added into medium in the first day after differentiation of cells.The expression of PPARγ mRNA in differentiated adipocytes were detected by reverse trancripaton PCR(RT PCR).Results The differentiation of preadipocyte presented the similar procedure and outcome between the TAO group and normal group.Differentiated adipocyte was stained into the jacinth by oil red O.The expression of PPARγ mRNA in differentiated cells was gradually declined with the increase of concentration of recombinant human resistin (F=241.341,P＜0.01).A dose dependent inhibitory effect was detected in the expression of PPARγ mRNA.The weakest expression of PPARγ mRNA in differentiated cells was 100ng/mL resistin group.Conclusion The recombinant human resistin has an inhibitory effect on the differentiation of orbital preadipocytes by reducing the expression of adipose related genes.Resistin is probably a new research approach to treatment of TAO.

Objective To assess the effects of zinc protoporphyrin (ZnPP), an inhibitor of the heme oxygenase (HO), on the colonic interstitial cells of Cajal (ICC) of diabetic rats with colonic slow transit. Methods Diabetes mellitus (DM) model was induced by intraperitoneal injection of streptozotocin (STZ) in Sprague-Dawley rats. Twenty four successfully established DM rats were selected, and 16 healthy rats were served as controls. Six weeks later, gastrointestional (GI) dysfunction was observed by charcoal propulsion experiment in 8 DM rats and 8 controls. The rest rats in DM group were divided into 2 groups: DM rats intraperitoneal injected with PBS (n=8) or with 10 μmol/kg of ZnPP (n = 8) every other day for 3 weeks. The rats in control group (n = 8) were intraperitoneally injected with PBS. The levels of HO and c-kit (the special receptor of ICC) expression were detected by Western blotting. The distribution of ICC was observed by immunohistochemistry and the area of c-kit positive cells was counted. Results The GI propulsion rate in DM rats interfered with PBS was significantly declined compared to that in the controls (63.0%± 1.2% vs 71.8%±2.0%, P<0.05). But it was improved in DM rats interfered with ZnPP (72.5± 2.6%, P<0.05), which showed no significant differentee with that in control group (P>0.05). The expression of HO-1 in close and distant colon of DM rats interfered with ZnPP was decreased (P< 0.05). The expression of HO-2 in close colon and the area of c-kit positive cells of DM rats interfered with PBS was reduced compared with that in controls (P<0.05), but both were improved in DM rats interfered with ZnPP (P<0. 05). Conclusion Administration of ZnPP might be able to protect ICC by its blockage of HO-1 in DM rats with gastrointestinal dysfunction.

OBJECTIVE: To investigate the characteristics of air-conducted ocular vestibular-evoked myogenic potential(oVEMP) in patients with sudden sensorineural hearing loss (SSHL). So as to understanding the range and the degree of the vestibular system damage in patients with SSHL. METHOD: Thirty-five cases of unilateral SSHL were enrolled as the observing group from December in 2013 to December in 2014. 500 Hz air-conducted tone burst was employed as stimulation. Fifity-five healthy young subjects were recruited as the control group. The results were compared between the affected ears, the contralateral ears and the normal controls. RESULT: Thirty-five patients with SSHL, 31 of them in both ears lead to oVEMP Waveform, 4 sick ears did not elicit oVEMP waveform, extraction rate of 88%. 95 dBHL air-conducted get the latencies of P1 and N1, P1-N1 interval, peak-to-peak P1-N1 amplitude in healthy ear were (11.92 ± 0.85)ms; (17.07 ± 1.04)ms, (5.15 ± 0.69)ms, (5.44 ± 2.53) µv. 95 dBHL air-conducted get the latencies of P1 and N1, P1-N1 interval, peak-to-peak P1-N1 amplitude in sick ear were (12.16 ± 0.76) ms; (16.94 ± 2.57)ms, (5.16 ± 0.73)ms, (2.89 ± 1.66) v. The 55 cases (110 ears) were elicited P1-N1 complex typical, extraction rate was 100%. The threshold of oVEMP examination was (82.23 ± 2.92) dBHL, 95 dBHL air-conducted get the latencies of P1 and N1, P1-N1 interval, peak-to-peak P1-N1 amplitude in these healthy young people were (11.53 ± 0.80)ms, (16.61 ± 0.87) ms, (5.18 ± 1.04) ms, (5.96 ± 2.59) µv, there were no significant differences between the affected ears, the contralateral ears and the normal controls in the latencies P1 and N1, P1-N1 interval. The wave amplitude in SSHL were lower than the healthy ear and the healthy control group. CONCLUSION Through the detection of oVEMP in patients with SSHL,we observed that P1-N1 wave amplitude decreased, and it may be related to the damage of the utricle and vestibular nerve.

Objective To investigate the diagnosis and treatments of delayed endolymphatic hydrops(DEH).Methods A restrospective study was conducted in 37 cases of DEH.who were tested with pure tone threshold,vestibular evoked myogenic potentials,high stimulation rate auditory brainstem response audiometry and vestibular ruction test.Conservative drug therapy was the major treatment.Results All the 37 patients had sensorineural hearing loss up to the medium-severe degrees at least.Twenty-five had hearing loss and endolymphatic hydrops on the same side,nine had contralateral type and three bilateral type.Ten cases had abnormal horizontal semicircular canal(HSCC) hydrops and saccular hydrops.Nine cases had abnormal HSCC function and nomal saccular function.Fifteen cases had abnormal saccular function and normal HSCC function.Twenty-five abnomalVEMP showed of loss of p13-n23,prolonged latencies of p13 and depressed amplitude cases with of p13-n23.18 cases were completely relieved from vertigo in a week.17 cases improved until totally relieved in two weeks,while the rest 2 cases that were subject to chemistry labyrinthectomy free of vertigo attack.Conclusion Pure tone threshold,EcochG,bithermal caloric test and vestibular evoked myogenic potentials are important diagnosis methods of delayed endolymphatic hydrops.Consevative drug therapy,especially diuretics and vascular dilation may play a major role in the treatment of delayed endolymphatic hydrops.

Objective To evaluate the effects and toxic side-effects of radiotherapy combined with xeloda or carboplatin respectively for locally advanced esophagus carcinoma.Methods 74 cases with locally advanced esophagus carcinoma were randomly allocated into two groups.One group received radiotherapy combined with Xeloda,500mg at a time,twice a day,taken orally from the beginning of radiotherapy till end of treatment.The second group received radiotherapy combined with Carboplatin by intravenous drip at 100mg a day,for 5 days,from the first week of radiotherapy.Results The overall response rate in the radiotherapy combined with Xeloda group was 91.4％ and 89.7％ in the radiotherapy combined with Carboplatin group.The difference between the two groups was not statistically significant(P ＞0.05 ).Kaplan-Meier survival analysis showed no statistically significant differences in survival between the two groups.The toxic side-effects of gastrointestinal tract,reaction myelosuppression and late radiation reaction were notably alleviated in the Xeloda group compared with the Carboplatin group.Conclusion Compared with Carboplatin,Xeloda combined with radiotherapy had less toxic side-effects for treatment of advanced esophagus carcinoma,with an equal local control rate,which worthy of clinical application.

Objective To evaluate the clinical effectiveness and the major toxic effect of radiotherapy combined with docetaxol and cisplatin respectively in the treatment of locally advanced non-small cell lung cancer (NSCLC).Methods 98 patients with locally advanced NSCLC were randomly divided into two groups.All of the patients were treated with 3D-CRT.One group was treated combined with docetaxel,20mg/m2,every week,totally 6 times.The other group was treated combined with cisplatin,30mg/m2,every week,totally 6 times.The total dose was 60 ～66Gy,2Gy/F,5 times each week for 5 ～7 weeks.The clinical effect and the major toxic effect between two groups were compared.Results The median survival time in group that treated with docetaxol was 17.2 months,median progression-free survival time was 13.5 months,and the 1,2 and 3-year survival rates of the patients were 78.6％,35.7％ and 19.5％ respectively.The median survival time in group that treated with cisplatin was 16 months,median progression-free survival time was 16.5 months,and the 1,2 and 3-year survival rates of the patients were 74％,34％ and 20％ respectively.The differences between two group were not stetisticelly significant( P ＞0.05 ).However,the side effect of the stomach and intestine and late radiation complication in group treated with docetaxol were slighter than those in group treated with cisplatin.Conclusion The clinical effect of radiotherapy combined with docetaxol in the treatment of locally advanced NSCLC was equal to radiotherapy combined with cisplatin.But radiotherapy combined with docetaxol has a slighter and acceptable toxic effect,which was worth the clinical application.

As an inhibitory amino acid similar to gama-aminobutyric acid,taurine can activate the corticostriatal pathway as an endogenous ligand for glycine receptors,establishing equilibrium between the excitatory and inhibitory processes in the brain.In mammalian brains,taurine concentrations increase during the developmental period of the brain until weaning,and subsequently decline reaching stable concentrations in adulthood.With abilities of anti-oxidative stress,anti-inflammatory and anti-apoptosis,taurine can improve the hypoxic-ischemic brain injury,promote the proliferation and differentiation of neurons and affect brain development,It needs more investigations to prove when and how taurine supplementation during gestation,baby,children or adult can assist the development of the brain and prevent the damage of the brain from hypoxic and ischemic damage.
