Objective To investigate the efficacy and outcome in newly diagnosed multiple myeloma (MM) patients with renal insufficiency using bortezomib-or thalidomide-based regimens as front line treatment.Method Sixty-nine newly diagnosed MM patients with renal insufficiency were retrospectively analyzed from August 2006 to August 2014.Results ① Among thirty-nine patients with bortezomib based regimens (the bortezomib group),the overall response rate (ORR) was 89.7％ and complete response (CR) plus near CR(nCR) rate was 41.0％.By contrast,among thirty patients with thalidomide based regimens (the thalidomide group),the ORR was 83.3％ and CR + nCR rate was 26.7％.There was no significant difference of either ORR or CR + nCR rate between bortezomib and thalidomide groups.② The improvement rate of renal function in bortezomib group and thalidomide group were 87.2％ and 60.0％respectively (P =0.012).The median duration time of renal injury was 45 days in 52 patients with renal function improved,which was significantly shorter compared with 222 days in 17 patients without improvement (P ＜ 0.05).There was no difference of median serum creatinine and creatinine clearance rate between the two groups.③ The median progression-free survival (PFS) and the overall survival (OS) were 18 and 33.5 months,respectively in all patients.The three-year and five-year OS rates were 57％ and 17％,respectively.The median PFS was 19 months in bortezomib group,while it was only 12 months in thalidomide group (P =0.023).The median OS were 36.5 months and 25.5 months respectively,which was no difference (P =0.285).Conclusions The newly diagnosed MM patients with renal insufficiency could get higher ORR and the longer PFS using bortezomib-containing regimens as initial therapy.Meanwhile the improvement rate of renal function and the living quality in patients with bortezomib are better compared with those with thalidomide based treatment.

Objective:This study investigated the clinical characteristics of multiple myeloma with early death in the era of novel drugs. Methods:Medical records from 188 patients diagnosed from January 2009 to December 2015 were retrospectively reviewed, showing that early death occurred in 19 patients. Early death was defined as death by any cause within the first year after diagnosis. Results:(1) Early mortality was 10.1%, and the median age was 67 years old (range:40-84 years). Eight cases presented IgG type, and 11 cases were non-IgG type. All 19 patients were diagnosed to be at stageⅢin accordance with the Durie–Salmon staging system, and renal insufficiency occurred in 10 patients. In accordance with the International Staging System (ISS), four patients were diagnosed to be at stageⅡ, whereas 15 other patients were at stageⅢ. Extramedullary plasmacytoma (EMP) occurred in six cases, whereas 10 cases pre-sented high-risk patients with cytogenetic abnormalities. Elevated lactate dehydrogenase (LDH) was found in five cases, amyloidosis was detected in three patients, and secondary plasma cell leukemia was observed in two cases. The median score of performance sta-tus (KPS) was 70 (range: 20-80). A total of 16 patients were treated with bortezomib, and 3 patients were treated with CADT. (2) Among the 13 patients who were evaluated, the overall response rate was 46.2%(6/13), and the complete response (CR) and near-CR rate was 7.7%(1/13). (3) The median overall survival was 3 (1-11.5) months, although the two patients with secondary plasma cell leu-kemia survived for less than 2 months. (4) Eight patients died of disease progression (42.1%), eight patients died of severe infections (42.1%), and three patients died of thrombotic events. Conclusion:The important causes of early death include the following:high-risk cytogenetics, elevated LDH, EMP, amyloidosis, advanced age, poor performance status, and serious complications during treat-ment. In the era of novel drugs, we should improve early diagnosis rates and explore individualized treatment for high-risk multiple my-eloma for the benefit of a wide range of patients.

OBJECTIVETo study the interaction among aquaporin1 (AQP), aquaporin2 (AQP2) and antisecretory factor( AF) , and their expression in the rat inner ear for furthur understanding of Meniere' s disease.

METHODSInner ear tissue section of six healthy male Sprague-Dawley rats was performed and Envision immunochemical staining was applied to detect the expression of AF, AQP1 and AQP2 in the rat inner ear. Vestibular and cochlear tissues of twenty healthy male Sprague-Dawley rats were dissected. Coimmunoprecipitation and Western Blot were used to specifically immunoprecipitate AF protein in the vestibular and cochlear tissues with monoclonal antibodies against AQP1 and polyclonal antibodies antibodies against AQP2 to detect the above precipitate with specific antibodies against AF.

RESULTS(1) AF was widely distributed in the inner ear, such as marginal cells of stria vascularis , five classes of spiral ligament fibrocyte , Reissner's membrane, basilar membrane, ampullar crest and so on with mild or moderate staining. In addition, round membrane was moderately or markedly stained. Positive immunostaining was found in the cochlear spiral ganglion, vestibular nerve and cochlear nerve. AQP1 was distributed in the intermediate cells in stria vascularis, type III fibrocyte of spiral ligament, basilar membrane and round membrane with moderate to marked degree of immunostaining intensity. AQP2 was mainly localized to the type II, IV, and V fibrocyte of spiral ligament, with moderate to marked degree of immunostaining intensity, round membrane was weakly stained. (2) No band was observed in the control and a single immunoreactive band of 60 000 was observed, which was equal to the molecular mass of AF.

CONCLUSIONS(1) AF, AQP1 and AQP2 have its individual specific localization in the rat inner ear, which was close to the parts of endolymph, so regulating water of the endolymph may be possible. (2) The range of localization of AF overlapped the distribution of AQP1 and AQP2. The results showed the existence of AF protein in the immunoprecipitate using co-immunoprecipitation combined with Western Blot. It suggested that the interaction between AQP1, AQP2 and AF might be possible.
