Objective To explore the clinical significance of changes of serum.interleukin 17(IL -17), interleukin 18(IL -18)and interleukin 18 binding protein(IL -18BP)in patients with AA.Methods Serum IL -17,IL -18 and IL -18BP levels were measured by ELISA in 50 patients with AA and 52 health control.Results The levels of serum IL -17,IL -18 and IL -18BP in the AA group were (216.41 ±22.24)μg/L,(402.37 ± 59.76)ng/L and (8.79 ±2.61 )μg/L respectively,which were higher than those in the healthy control group of (90.36 ±9.78)μg/L,(136.48 ±20.25)ng/L and (2.01 ±0.68)μg/L(t =37.41,30.46,18.13,all P <0.01). And the levels of serum IL -17,IL -18 and IL -18BP in AAA group were (267.76 ±30.17)μg/L,(479.41 ± 68.76)ng/Land (11.72 ±3.29)μg/L,which were higher than those in the CAA group of (156.48 ±18.36)μg/L, (312.47 ±40.61)ng/L and (5.36 ±1.45)μg/L (t =15.73,10.43,8.92,all P <0.01).The serum level of IL -17 was positive correlation with the levels of IL -18 and IL -18BP in patients with AA (r =0.527,r =0.489,all P <0.05),the serum level of IL -18 was also positive correlation with the level of IL -18BP(r =0.731,P <0.01). Conclusion IL -17,IL -18 and IL -18BP may participate in the pathogenesis of AA,and there is a certain correla-tion,which may influence the process of AA.

Objective To investigate the diagnosis and treatment of pulmonary tuberculosis in renal transplantation recipients.Method The clinical data of 8 renal transplantation recipients suffering from pulmonary tuberculosis infection were retrospectively analyzed.Result Fever,cough and expectoration were the most common symptoms,however,lacking typicality.Images of chest Xray and CT scan were various and couldn't verify TB infection from pneumonia.Seven of 8 cases were diagnosed through invasive methods,either bronchofibroscope or fiberthoracoscopy.Immunosuppressants were decreased in all cases.Three-drug regimens,including isoniazide,rifampicin and ethambutol or pyrazinarnide,were administrated as anti-tuberculosis chemotherapy.All the cases were cured,without episodes like acute rejection and liver function impairment.Conclusion Routine examinations are not sufficient to diagnose pulmonary tuberculosis in kidney transplantation recipients.While,invasive methods like bronchofibroscope and fiberthoracoscope are helpful.When diagnosed,patients should receive normative anti-tuberculosis treatment and immunosuppressive agents adjustment,which can benefit the prognosis of pulmonary tuberculosis in renal transplantation recipients.

OBJECTIVE: To investigate the effecacy of cochlear implantation (CI) improving hearing of Lermoyez's syndrome, we retrospectively analyzed a case of Lermoyez's syndrome whose left ear was extremely severe sensorineural deafness and right ear was severe sensorineural deafness. METHOD: The patient had completed preoperative audiological examination , vestibular function and imaging examination, then was carried out bilateral endolymphatic sac decompression and left side CI. Follow up after the surgery. RESULT: The vertigo could be controlled very well after the bilateral endolymphatic sac decompression surgery, but the hearing loss couldn't be control, so CI was carried out to improve hearing and speech recognition rate. The contralateral hearing also improved significantly after the operation. CONCLUSION Endolymphatic sac decompression can effectively control. Ménière's disease in patients with vertigo attacks. CI can improve patients' hearing, and speech recognition rate and, also could improve the quality of life. CI was the first choice for the patient of 4 stage Ménière's disease.

OBJECTIVE: To compare the vertigo controlling situation between the endolymphatic sac decompression(ELSD) and semicircular canal occlusion (SCO) in stage 4 Ménière disease. METHOD: Fourteen patients who underwent endolymphatic sac decompression and 9 patients who underwent semicircular canal occlusion from 2009 to 2013 were followed. All patients has complete preoperative examination and postoperative follow-up. RESULT: The vetigo control of the patients underwent endolymphatic sac decompression: completely control 35.7%; basic control 28.6%; partly control 14.3%; the vetigo control of the patients underwent semicircular canal occlusion: completely control 88.9%; basic control 11.1%. CONCLUSION ELSD and SCO are alternative methods for the patients of stage 4. SCO has a much highter complete vertigo control rate. For the patients without practical listening, SCO is a better choice.

OBJECTIVE: To evaluate the efficacy and safety of Dinggui Oil Capsule in treating irritable bowel syndrome (IBS) with stagnation of qi and cold. METHODS: A prospective, randomized, placebo-controlled, double-blind clinical study was undertaken. One hundred and ninety-eight patients with IBS and syndrome of stagnation of qi and cold were randomly divided into high-dose Dinggui Oil group (DGO-H, 1.2 g, 3 times daily; n=66), low-dose Dinggui Oil group (DGO-L, 0.8 g, 3 times daily, n=66), and placebo group (placebo, 5.0 g, 3 times daily, n=66). Patients in the three groups were all treated for 2 weeks. RESULTS: The total significant effective rates for IBS were 54.1%, 28.8% and 21.9% in the DGO-H, DGO-L, and placebo groups, and the total effective rates for the syndrome of stagnation of qi and cold were 54.1%, 25.8% and 23.4% in the three groups, respectively. Dinggui Oil Capsule showed a higher efficacy than the placebo in relieving the abdominal pain (P<0.01). No adverse effects were found in this trial. CONCLUSION: Dinggui Oil Capsule is effective and safe in relieving abdominal pain due to IBS with stagnation of qi and cold.

OBJECTIVETo study the effect of selenium (Se) and iodine (I) and the compound of both on the proto-oncogenes c-fos and c-jun mRNA and their protein expression in the cultured rat hippocampus neurons.

OBJECTIVEStudy on the promoter effects of sodium butyrate in high or low dosages on carcinogenesis process, based on the immortalization of human fetal esophageal epithelium induced by human papillomavirus (HPV) 18E(6)E(7) genes.

METHODSThe immortalized esophageal epithelium SHEE was treated with high concentration of the sodium butyrate (80 mmol/L) and then with low concentration (5 mmol/L) for 8 weeks respectively. The cells were cultured continuously without sodium butyrate for 14 weeks. The morphology, proliferation and apoptosis of the cells were studied by phase contrast microscopy, immunohistochemistry and flow cytometry. The dead and the viable cells were assayed by fluorescent microscopy with Hoechst 33342 and Propidium iodide staining. Tumorigenesis of the cells was assessed by soft agar colony formation and by transplantation of cells into nude mice and SCID mice.

RESULTSWhen cells were exposed to high concentration of sodium butyrate, cell death was increased leaving few live cells. When cells were cultured in the medium with low concentration of sodium butyrate, the first proliferative stage appeared. Removal of the butyrate caused the cell to enter a crisis stage with a long doubling time resembling senescent cells. After the crisis stage, the cells progressed to the second proliferation stage with continuous replication and atypical hyperplasia. At the end of the second proliferative stage, carcinogenesis of the cells appeared with large colonies in soft-agar and tumor formation in transplanted SCID mice and nude mice.

CONCLUSIONSThe malignant change of the immortalized epithelium by the effects of sodium butyrate is the consequence of a two-stage mortality mechanism: cells death by butyrate cytotoxicity and cell crisis by abrogation of sodium butyrate. These data reveal that in high dosage, sodium butyrate induces cell death and in low dosage, it induces cell proliferation, which emphasizes the importance of butyrate as a promotor of carcinogenesis.

Objective To compare the clinical effect of ifosfamide in combination with liposomal doxorubicin and dexamethasone (CDD) in the treatment of relapsed/refractory multiple myeloma (MM) with or without extramedullary plasmacytoma (EMP). Methods The clinical data of 71 relapsed/refractory MM patients treated with CDD regimen from January 2011 to December 2016 were retrospectively analyzed, including 48 patients with EMP(group A)and 23 patients without EMP (group B).One cycle of the CDD treatment was 21 d or 28 d and efficacy analysis was performed after every two cycles.Results The overall response rate in group A was 43.8%(21/48)and the complete remission and near complete remission rate was 8.3%(4/48);the overall response rate in group B was 65.2%(15/23)and the complete remission and near complete remission rate was 13.0% (3/23). There were no statistically significant differences between the two groups(χ2=1.203,0.659,P>0.05).The progression-free survival (PFS)time in group A was(8.6 ± 3.3)months, while the PFS time in group B was(7.9 ± 2.5)months and there was no significant difference between the two groups(t=1.009,P>0.05).There was no significant difference about incidence rate of adverse effects between the two groups(P>0.05).Conclusions CDD regimen can be used for the treatment of relapsed/refractory MM with or without EMP, the PFS and drug related adverse effects are similar, especially in patients with EMP.

Research on application of ultrasound has made continuous progress in airway manage-ment,providing theoretical basis and new ideas for clinical use of ultrasound in airway management,and ex-panding the application range of ultrasound in airway management.Ultrasound can develop real-time imaging and measure almost all the tissue structures of the whole airway,ensuring the accurate locating and measure-ment of airway anatomical structure,which offers objective theoretical support for airway evaluation.Its char-acteristic of real-time imaging also helps to guide endotracheal intubation,determine the position of endotra-cheal tube and laryngeal mask airway,and assess gastric contents.Artificial intelligence improves the accu-racy and efficiency of ultrasonic identification of anatomical structure,which promotes the expanded applica-tion of ultrasound in airway management.This article briefly outlines the recent advance in the application of ultrasound in guiding endotracheal intubation,confirming endotracheal intubation,detecting laryngeal mask airway position,predicting successful tracheal extubation,predicting difficult airway,locating airway ana-tomical structure,and assessing the risk of gastric aspiration,and discusses the application of ultrasound combined with artificial intelligence in airway management.
