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.

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 To observe temporal expression of matrix metalloproteinases(MMP-13) and tissue inhibitor of metalloproteina-ses-1 (TIMP-1) in lung of newborn rats with hyperoxia induced chronic lung disease (CLD),and to explore the relationship of CLD with MMPs.Methods The neonatal rats within 24 hours after birth were randomly divided into hyperoxia-exposed group(n=40) and control group(n=40).On postnatal 1,3,7,14 and 21 days,lung tissue of rats in 2 groups were collected.Lung histological changes were evaluated by hematoxylin and eosin and Masson stain;Collagen Ⅰ was detected by enzyme linked immunoadsorbent assay;MMP-13 and TIMP-1 were identifide by immunohistochemistry.Results Exposured to hyperoxia enviroment for 21 days,the number of alveolar decreased,terminal air space enlarged,inter-alveolar septa thickened,and deposition of interstitial collagen fibers.On 14 and 21 days,collagen Ⅰ in the lung of hyperoxia-exposed group increased significantly compared with that of control group(P0.05),obviously decreased on 21 day(P

Individual stature estimation is one of the most important contents of forensic anthropology. Currently, it has been used that the regression equations established by the data collected by direct measurement or radiological techniques in a certain group of limbs, irregular bones, and anatomic landmarks. Due to the impact of population mobility, human physical improvement, racial and geographic differences, estimation of individual stature should be a regular study. This paper reviews the different methods of stature estimation, briefly describes the advantages and disadvantages of each method, and prospects a new research direction.

Objective To investigate the effects of magnesium isoglycyrrhizinate on liver function of patients with gastrointestinal cancer following chemotherapy.Methods From Apr.2012 to Dec.2015,a total of 168 cases of patients with gastrointestinal cancer following chemotherapy were enrolled,and were randomly divided into observation group(84 cases) and control group(84 cases).Each of the two groups was divided into A group(42 cases) and B group(42 cases) according to the treatment methods.Patients of observation group(including observation A group and observation B group) were treated with magnesium isoglycyrrhizinate,while patients of control group(including control A group and control B group) were treated with glutathione.Patients of A group(including observation A group and control A group) were treated with FOLFOX4 regimen,while patients of B group(including observation B group and control B group) were treated with XELOX regimen.The incidence of abnormal liver function and changes of the levels of liver function of each group were analyzed and compared.Results After the appropriate treatment,the abnormal rate of liver function of observation group were significantly lower than control group(P<0.05).After treatment,levels of liver function parameters in observation group and control group were all significantly increased(P<0.05),and those in control group were higher than observation group(P<0.05).After treatment,levels of liver function parameters in observation A group and control A group were all significantly increased(P<0.05),and those in control A group were higher than observation A group(P<0.05).After treatment,levels of liver function parameters in observation B group and control B group were all significantly increased(P<0.05),and those in control B group were higher than observation B group(P<0.05).Conclusion Magnesium isoglycyrrhizinate could be with protection effects on liver function of patients with gastrointestinal cancer following chemotherapy,which might be worthy of promotion.

Objective To explore the effect of iodine excess on bone metabolism in experimental autoimmune thyroiditis (EAT) rats. Methods We selected 36 female Lewis rats with body weight of (131 ± 15)g,and divided them into 3 groups randomly: control group, EAT group and EAT + high iodine group, assuring 12 rats in every group. These rats were fed fodder with different concentration of iodine(0.9,0.9, 18.0 mg/kg), and rats in EAT group and EAT + high iodine group were immunized with pig thyroglobulin(pTG) and complete Freund's adjuvant(CFA) to create EAT model. After two weeks, the pathological changes of the thyroid tissues were observed,and the serum thyroid autoantibody[thyroglobulin antibody(TGAb) and thyroid microsomal antibody(TMAb)], the thyroid hormone levels[triiodo thyronine(T3) and thyrine(T4)] and some relevant data of bone metabolism[bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), C-terminal propeptide of type Ⅰ procollagen (PICP),C-terminal telopeptide of type Ⅰ collagen (ICTP), insulin-like growth factor- 1 ( IGF- 1 ), osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL)] were measured. Results Inflammatory cell infiltration and local follicular structural damage were observed in the thyroid tissues of EAT rats in EAT group and EAT + high iodine group, and the pathological changes of EAT + high iodine group were mainly thyroid follicular expansion and integration. The level of serum TGAb, TMAb, T3 and T4 of EAT rats in EAT group and EAT + high iodine group[ (63.01 ± 12.36)%, (60.62 ± 11.24)%, (3.78 ± 1.43), (125.12 ± 16.00)pmol/L and (75.00 ± 15.44)%,(72.15 ± 15.00)%, (3.69 ± 0.91 ), (149.40 ± 20.67)pmol/L] were higher than those of the control group[ (4.47 ±1.04)%, (5.73 ± 1.01 )%, (0.75 ± 0.12), (76.91 ± 9.30)pmol/L, all P ＜ 0.05], and the level of serum TGAb,TMAb and T4 of EAT rats in EAT + high iodine group were higher than those of the EAT group(all P ＜ 0.05).The level of serum BGP, PICP and IGF- 1 in EAT group[ ( 1.70 ± 0.31 ), ( 11.31 ± 1.52) μg/L, (0.31 ± 0.06 ) mg/L]were lower than those of the control group[ (8.60 ± 0.33), (14.28 ± 3.10)μg/L, (1.16 ± 0.02)mg/L, all P ＜0.05], and the level of serum TRAP, ICTP, OPG and RANKL[ ( 19.88 ± 3.60)ng/L, (2.43 ± 0.82), (22.36 ± 2.80),( 1.35 ± 0.23 )μg/L] were higher than those of the control group[ ( 14.57 ± 3.56)ng/L, (0.50 ± 0.20), (1.61 ± 0.34),(0.10 ± 0.02)μg/L, all P ＜ 0.05]; compared with EAT group, the level of PCIP and OPG in EAT + high iodine group [ (8.03 ± 1.84), ( 16.80 ± 3.79)μg/L] were obviously decreased(all P ＜ 0.05). Conclusions The reinforcement of differentiation and maturation of osteoblast in the EAT rats results in the increasing of bone resorption. The activity of osteoblast and osteoclast of the EAT rats are inhibited by excessive iodine, showing a low conversion-type osteoporosis.

Objective To construct a recombinant vector of sperm-specific human lactate dehydrogenase ( hLDH-C4 ), express it in Escherichia coli ( E. coli ) BL21 ( DE3 ) and utilize it in the detection of anti-sperm antibody. Methods The coding sequence of hLDH-C4 was amplified from human testis λTripIEx cDNA library, and inserted into pET-28a( + ) after restriction enzyme digestion with Hind Ⅲ and Xho Ⅰ. The resultant recombinant vector was used to transform E. coli BL21 ( DE3 ) and the His-Tag fused hLDH-C4 was expressed after induction with IPTG. Western blot was used to analyzed the recombinant protein and LDH activity of bacterial lysates was determined. An indirect ELISA method for the detection of anti-sperm antibody was established by using the recombinant hLDH-C4 as antigen matrix. Results pET-28a( + )-hLDHC was successfully established. The protein with size of 35kD could be induced by IPTG when the recombinant plasmid was transfected into E. coli BL21 ( DE3 ). Western blot showed that the recombinant protein could be specifically recognized beth by anti-His tag monoclonal antibody and by rabbit anti-human LDH-C4 antibody. In addition, the recombinant protein showed high-level LDH activity when the bacterial lysate after IPIG induction was used to check LDH activity. The recombinant hLDH-C4 was confirmed when it was used in indirect EL1SA to detect anti-hLDH-C4 antibody. Conclusions The coding sequence of hLDH-C4 is cloned into the vector pET-28a( + ) and recombinant hLDH-C4 was expressed at a high level in E. coli. The recombinant hLDH-C4 is useful in the detection of anti-sperm antibody.

Objective To investigate antifungal activities of AMB, ICZ, VRC, CBF against 72 strains of filamentous fungi in vitro. Methods Based on CLSI M38-P and M38-A scheme, MIC of antifungal drugs were determined. The growing inhibitory concentration of 100%, 100%,≥80%, for AMB, VRC ,ICZ act as respective MIC. For caspofungin, the minimal effective concentration (MEC) was determined as the lowest drug concentration showing morphology change of filaments. The fractional inhibitory concentration (FIC) was used to evaluate the effect of combination therapy. FIC was calculated by the following equation: FIC = MICcombination/MICA drug alone+ MICcombination/MICB drug alone. Results MIC90 of AMB, ICZ, CBF, VRC against 72 isolates of filamentous fungi were 8 μg/ml, 4 μg/ml, 2 μg/ml, 8 μg/ml, respectively. MICs range of combined AMB + ICZ, AMB + VRC, ICZ + VRC were 0. 125-16. 97, 0. 2452-1.25, and 0.0625-8. 25 μg/ml respectively. The percent of synergistic interaction of AMB + VRC against filamentous fungi (20.0%-88.9% ) was higher than those of AMB + ICZ ( 10.0% -62.5% ) and ICZ + VRC ( 20.0% - 44.4% ) ( P=0.007 <0.05 ). Conclusions The antifungal activities of four kinds antifungal drugs against 72 strains of filamentous fungi vary in vitro. The therapy of AMB combined with VRC is maybe better than AMB + ICZ and ICZ + VRC for severe fungi infection.
