Objective To discuss the effects of multimodal combination dialysis on Klotho protein, fibroblast growth factor-23 (FGF-23) and brain natriuretic peptide (BNP) in patients with maintenance hemodialysis (MHD). Methods A randomized controlled trial (RCT) was conducted. 120 patients who was diagnosed with chronic renal failure (CRF) uremia receiving MHD over 3 months admitted to Blood Purification Centre of Department of Nephrology of the Second People's Hospital of Guiyang from December 2015 to December 2016 were enrolled, who were randomly divided into hemodialysis (HD) group (HD for 8 times a month), HD + hemofiltration (HF) group (HD for 8 times a month + HF once a month), and HD + HF + hemoperfusion (HP) group (HD for 8 times a month + HF for 4 times a month + HP once a month), with 40 patients in each group. Before and after treatment for 6 months and 12 months, blood was taken from venous circuit tube, the serum Klotho protein and FGF-23 levels were determined by enzyme linked immunosorbent assay (ELISA), and the serum BNP level was determined by electrochemiluminescence. Results 120 patients with MHD were enrolled in the final analysis without withdrawal. There were no significant differences in the levels of Klotho protein, FGF-23, or BNP before enrollment among the three groups (all P > 0.05). Compared with those before enrollment, the levels of serum Klotho protein after enrollment in three groups showed a sustained upward tendency, which were higher in HD + HF + HP group than in HD + HF group and HD group (μg/L: 2.59±0.61, 1.63±0.35, 1.13±0.26 at 6 months, F = 119.374, P = 0.000; 6.98±1.21, 3.57±1.03, 2.12±0.43 at 12 months, F = 275.675, P = 0.000); the levels of FGF-23 showed a sustained downward tendency, which were lower in HD + HF + HP group than in HD + HF group and HD group (ng/L: 69.22±38.26, 132.28±61.18, 178.50±74.64 at 6 months, F = 33.509, P = 0.000; 32.81±17.32, 87.93±43.27, 146.33±69.28 at 12 months, F = 55.466, P = 0.000);the BNP showed a similar tendency as FGF-23 (ng/L: 4083.39±2864.53, 7245.69±4643.81, 7969.12±5360.85 at 6 months, F = 8.758, P = 0.000; 1521.86±894.63, 4554.32±1969.84, 5013.89±2033.64 at 12 months, F = 49.003, P = 0.000). Conclusion Multimodal combination dialysis can increase the Klotho protein level, and decrease the levels of FGF-23 and BNP in MHD patients with CRF uremia.

Objective To study the expression of BCL10 and associated chromosomal aberration in primary cutaneous marginal zone B-cell lymphoma (PCMZL). Methods Tissue specimens were collected from 17 patients with PCMZL. Immunohistochemistry was used to detect the expression of BCL10. Fluorescence in situ hybridization (FISH) was performed to examine the presence of API2-MALT1 fusion gene and chromosomal aberration in BCL10, MALT1 as well as IgH genes in these cases. Results Of these patients,94.1% (16/17) expressed BCL10 protein. The cytoplasmic expression of BCL10 was observed in 64.7% (11/17) of the patients, and nuclear expression in 29.4% (5/17). As shown by FISH test, neither API2-MALT1 fusion gene nor chromosomal aberration in BCL10, MALT1 or IgH genes was present in these patients. Conclusions Compared with MALT lymphomas originating from tissues other than skin, PCMZL is uncommonly associated with chromosomal abnormalities; it is possible that there are unknown factors contributing to its tumorigenesis. Nuclear BCL10 is unrelated to the presence of chromosomal aberration in BCL10, MALT1 or IgH genes. Further follow-up is required to clarify the association between nucle ar BCL10 and poor prognosis of PCMZL.

Objective:To study the correlation of β-fibrinogen-854G/A,-455G/A,-249C/T,-148C/T,448G/A and BcI-1G/A polymorphisms, functional expression of plasma fibrinogen concentration, molecular reactivity, and the type of cerebral infarction.Methods: A casecontrol study was used to analyze 54 patients with main-think cerebral infarction(MCI), 106 patients with penetrating-arterial cerebral infarction (PCI)and 160 heathy cases as control group in Kailuan Hospital between July 2002 and June 2003.Gene polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).Fg concentration, fibrin monomer polymerized velocity(FMPV), absorbance maximum(Amax), FMPV/Amax and biochemistry factors including TG were measured, Results: Fg concentration, FMPV, FMPV/Amax in the MCI group and TG, VLDL and FMPV in the PCI group were higher than in the control group(P＜0.05).The frequencies of854A and Bcl-1A alleles had significant difference among three groups,and the frequencies of GA and AA genotypes in the MCI and PCI groups were higher than in the control group(P＜0.05), however, no different genotypes and allele frequencies of the remaining sites were found in the three groups(P＞0.05).Fg concentration and FMPV of allele T carriers in the MCI group were less than that of-249C/C homozygous ones(P ＜0.05); FMPV/Amax of allele T carriers in the PCI group was higher than that of-148C/C homozygous ones(P＜0.05);with allele A carriers, Fg concentration of control group and FMPV of PCI group were higher than that of Bcl-1 wild homozygote(P＜0.05).Conclusion: Bβ-249 C/T polymorphism in the 5-flanking promoter region can influence the expression of plasma FMPV, Bβ-148 locus is the main regulation location of Fg molecular conglomerate function.Bcl-1 locus in the 3-flanking region is an important gene regulator of plasma Fg concentration, moreover,people with its mutated genotypes are susceptible to MCI.The abnormal plasma Fg concentration, FMPV/Amax and FMPV simultaneously are important risk factors for MCI, and only abnormal FMPV and TG are prone to PCI.

Cerebrospinal fluid proteomics, a branch of proteomics, is aimed to separate different types of cerebrospinal fluid proteins and identify differentially expressed protein sites through core analysis techniques.Since cerebrospinal fluid is directly connected with extracellular fluid of brain tissue, the abnormal change in the central nervous system could influence the composition of cerebrospinal fluid, such as peptides and proteins.Cerebrospinal fluid proteomics research gives insight into understanding of physiological and pathological changes of central nervous system(CNS), which is a supplement of cytological examination and biochemical test for CNS, and the technology provides a support for diagnosis and treatment of CNS diseases.Detecting cerebrospinal fluid proteomics is of great importance for the diagnosis,treatment and prognosis of CNS diseases.

Five presented muscle atrophy.None had sensory disturbances .All suffered diminished or disappeared tendon reflex , whereas Babinski signs were negative .Multi-focal conduction block ( CB) was confirmed by nerve conduction studies ( NCS) in all patients and 7 showed spontaneous potentials in needle electrode electromyography .Abnormal sensory nerve conduction was seen in 3 patients.Laboratory test revealed anti-ganglioside GM1 antibody in cerebrospinal fluid (CSF) in 6 cases and elevated CSF protein in 7 cases.Limb weakness alleviated greatly in 9 cases after intravenous immunoglobulin ( IVIg) treatment.But the other one reported poor response , who had long course of disease , serious limb weakness and obvious muscle atrophy .Motor nerve damage is the most important manifestation of MMN and sensory nerve damage may also appear .NCS is essential to the diagnosis of this disease , with CB as the characteristic electrophysiological feature .IVIg is an effective treatment.

Objective To investigate the relationship between iodine nutritional status and thyroid hormone levels,and to provide a guideline for monitoring iodine nutrition and thyroid function.Methods A crosssectional survey was performed by randomly selecting 341 samples (health pregnant women with a first child) from the Second People's Hospital of Guiyang,Bihai Community Medical Center and Jinhuayuan Community Center from October 2015 to September 2016.Levels of serum hormones and antibodies relative to throid of pregnant women in Guanshan Lake District of Guiyang at different pregnant times,which included throid stimulating hormone (TSH),free three triiodothyronine (FT3),free thyroxine (FT4),thyroid peroxidase antibody (TPOAb),and thyroglobulin antibody (TgAb),were measured by the electrochemical luminescence method,and urinary iodine levels were measured by heat digestion.Results The median urinary iodine of pregnant women at early,middle and late stages (T1,T2 and T3 stages) were 191.8,198.9 and 214.5 μg/L,respectively.FT3 increased first and then decreased during pregnancy.Levels of FT3 in the T2 stage were significandy higher than those in T1 and T3 stages (FT3 medians at the three stages were 4.49,4.83 and 4.57 pmol/L),and the differences were statistically significant (P ＜ 0.05).FT4 levels decreased during pregnancy (FT4 medians at the three stages were 16.32,14.65 and 13.22 pmol/L),and the differences among the three groups were statistically significant (H =67.517,P ＜ 0.01).Statistically significant differences were not found in the TSH levels among the three groups ~SH medians at the three stages were 2.05,2.01 and 2.39 mU/L,H =1.297,P ＞ 0.05).The medians of TPOAb and TgAb during T2 stage (9.60 and 19.02 U/ml) were significantly lower than those of other groups (18.92 and 24.75 U/ml at stage T1,and 13.46 and 22.06 U/ml at stage T3),and the differences were statistically significant (P ＜ 0.05).TSH levels were consistent with urinary iodine levels.TSH levels in the excessive iodine group (urine iodine:250 ～ 499 μg/L,2.54 mU/L) were significantly higher than those in the adequate iodine group (urine iodine:150 ～ 249 μg/L,1.97 mU/L) and deficient iodine group (urine iodine:＜ 150 μg/L,1.91 mU/L),and the differences were statistically significant (P ＜ 0.05).No correlations were found between levels of FT3,FT4,TPOAb,TgAb and levels of the urinary iodine.There was a significant positive correlation between urinary iodine levels and TSH levels (rs =0.180,P ＜ 0.01).The incidence of abnormal thyroid function in pregnant women was 29.33％ (100/341),which was composed of clinical hypothyroidism (accounting for 0.88％,3/341),subclinical hypothyroidism (accounting for 25.51％,87/341),low T4 level (accounting for 1.76％,6/341),clinical hyperthyroidism (accounting for 0.59％,2/341),subclinical hyperthyroidism (accounting for 0.59％,2/341),and TPOAb positive and TgAb positive (accounting for 12.61％,43/341).These abnormalities occurred mainly in the T1 and T3 stages.The prevalence of subclinical hypothyroidism increased with increasing of urinary iodine level,and the difference was statistically significant (x2 =11.269,P ＜ 0.05).Conclusion There is a positive correlation between pregnancy iodine nutritional status and its TSH level,so it is important to monitor the level of urinary iodine during pregnancy and to screen the thyroid function and antibodies in the early and middle time of pregnancy.

OBJECTIVETo explore the clinicopathologic features of CD30-positive sinusoidal large B-cell lymphoma (CD30 + SLBCL) and its relative correlation with Epstein-Barr virus (EBV).

METHODSTwo cases of CD30 + SLBCL, a 65-year-old men and a 85-year-old women were morphologically and immunophenotypically analyzed. EBV status was also evaluated through not only the polymerase chain reaction (PCR) amplification to the EBV Bam HIW DNA sequence, but also an immunohistochemical detection of the latent membrane protein 1 (LMP1).

RESULTSThe patients presented with similarly superficial lymphadenopathy. One of them died of the tumor within 10 months. Microscopically, both of the neoplasms were characterized by a cohesive sinus growth pattern and the monomorphic cytology of the tumor cells. Immunohistochemically, They were both positive for CD45, CD30, and CD20 or CD79alpha, whereas neither expressed EMA, ALK1, nor any histiocytic/T-lineage markers. No evidence of EBV-infection could be found either.

CONCLUSIONSCD30 + SLBCL is a morphologically and immunophenotypically distinctive variant of diffuse large B-cell lymphoma, which should be distinguished from T/null cell type anaplastic large cell lymphoma and some other nodal lesions with a predominantly sinusoidal infiltrative pattern. CD30 + SLBCL may not be correlation with EBV.

Objective To evaluate the efficacy of accelerated partial breast irradiation ( APBI ) and whole breast irradiation ( WBI ) with simultaneous integrated boost ( SIB ) from the perspective of economics, and provide a reference for postoperative adjuvant therapy mode selection for early-stage breast cancer after breast-conserving surgery. Methods A total of 355 early-stage breast cancer patients who underwent APBI or WBI-SIB after breast-conserving surgery were evaluated on efficacy and cost-effectiveness, of which 177 patients received APBI, and 178 patients received WBI-SIB. Survival analysis was done according to treatment received. NCI-CTC 3.0 was used to score the toxicities. Breast aesthetic outcome were evaluated with Harris standards. Results Median follow-up was 42 months ( 5.8 -92.7 months) . The 3-year locoregional recurrence free survival( LRFS) rates in APBI group and WBI-SIB group were 98.2％ and 97.6％, distant metastasis free survival( DMFS) were 94.3％ and 93.7％, disease-free survival ( DFS) were 93.1％ and 91.6％, and overall survival 95.5％ and 94.3％, respectively, without statistically significant differences(P>0.05). Compared with WBI-SIB group, the acute reaction rates in APBI group decreased from 5. 6％ to 3.4％(χ2 =6.044, P <0. 05), and late reactions from 5.6％ to 2.3％ (χ2 =6.149, P<0. 05), while the cosmetic outcome improved from 88.8％ to 93.8％(χ2 =5.22, P<0. 05). Moreover, the processing average time was shortened by 26.5 d (χ2 =40.76, P<0. 05). Conclusions After breast-conserving surgery, the efficacy of APBI showed no difference from WBI-SIB with respect to 3-year local control, disease-free survival, and overall survival, but displayed a significantly better toxicity profile and cost-effectiveness ratio for early breast cancer patients. It can be used as a good radiotherapy model after breast-conserving surgery in early-stage breast cancer.

Objective To investigate the changes of serum thyroid peroxidase(TPOAb)and thyroglobulin antibody(TGAb)and their relationship with thyroid function in pregnant women during different gestation period Methods Totally 341 cases of primiparae were selected from October 2015 to September 2016 and levels of se-rum thyrotropin(TSH),free triiodothyronine(FT3),free thyroxine(FT4),thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TgAb)were measured by electrochemiluminescence. Results The prevalence of thy-roid dysfunction and positive serum thyroid autoantibodies were 13.2%and 12.61%respectively,which mainly oc-curred in early and middle pregnancy. Thyroid dysfunction in subjects included hypothyroidism(0.59%),subclini-cal hypothyroidism(7.92%),low T4 hyperlipidemia(3.23%),hyperthyroidism(0.88%)and subclinical hyper-thyroidism(0.59%). The positive rate of TPOAb was significantly higher than that of TgAb(10.85% vs. 4.99%, P<0.01). The positive rate of TPOAb in women with thyroid disfunction was significantly higher than that in those with normal thyroid function(44.44%vs. 5.74%,P<0.01). TSH level of TPOAb positive subjects was higher than that of TPOAb negative ones(P<0.05,P<0.01);TSH level of TPOAb positive subjects with thyroid dysfunction were significantly higher than those of TPOAb negative subjects and TPOAb positive pregnant women but with nor-mal thyroid function(P < 0.01). The hypothyroidism prevalence rate of TPOAb positive subjects was significantly higher than that of TPOAb negative subjects in early and middle stage of pregnancy (P < 0.01). The prevalence rates of subclinical hypothyroidism ,low T4 hyperlipidemia and clinical hypothyroidism were significantly higher in TPOAb positive pregnant women(29.17%,20.83% and 8.33%)than those in TPOAb negative pregnant women (P < 0.01). Conclusions Thyroid dysfunction is closely related to positive status of TPOAb and TgAb in pregnancy,which could influence the outcome of pregnancy and the development of offspring. Since levels of TSH, FT3 and FT4 could not fully reveal thyroid function ,it is necessary to monitor the status of TPOAb and TgAb as early as possible for the early diagnosis and treatment of thyroid disease in pregnancy.

BACKGROUNDTo explore the therapeutic effect of bronchial artery infusion chemotherapy combined with immunotherapy for lung cancer with malignant hydrothorax.

METHODSSeventy-five lung cancer patients with malignant hydrothorax were randomly divided into the two groups: 38 patients were given intrathoracic chemotherapy and bronchial artery infusion chemotherapy combined with immunotherapy as observing group; 37cases only received intrathoracic chemotherapy as control group. Chi-square assay was performed to analyze the efficacy (responses for lung cancer and hydrothorax control) after the first course of treatment and the 1-, 2-year survival rates in the two groups.

RESULTSAfter the first course of treatment, the total responses for lung cancer were 31.58% (12/38) and 5.41% (2/37) in the observing group and control group (Chi-square=8.46, P < 0.01) respectively ; and responses for hydrothorax control were 86.84% and 64.86% respectively (Chi-square= 4.96, P <0.05). The 1- and 2-year survival rates in the observing group were 65.79% (25/38) and 26.32% (10/38) respectively, which were significantly higher than those of the control group (40.54% and 5.41%) respectively (Chi-square=4.80, P <0.05; Chi-square=6.10, P <0.05).

CONCLUSIONSThe intrathoracic chemotherapy combined with bronchial artery infusion chemotherapy and immunotherapy is quite effective in the treatment of lung cancer with malignant hydrothorax.
