Objective To construct recombinant prokaryotic plasmid DNA encoding mycobacterium tuberculosis (TB) heat shock protein 70 (HSP70) - Dnak gene obtained from pMT70, then purify its characterizes and the role of rHSP70 in tumor therapy. Methods Amplified by polymerase chain reaction (PCR) and with terminal modification, the Dnak gene was cloned into the vector with T7 promoter and was confirmed by restriction endonuclease digestion. So a new plasmid pMT70 - 3 was constructed and transformed in E. Coli. Strain BL21DE3. The engineering bacteria were induced by IPTG. Western-blot,natine-page and scanning were used to analyze the results. The human HSP70 were induced with peptides of lymphocytic leukemia cells of L1210 of mice in binding buffer which contain MgCl2 and ADP at 37 ℃ , then mice were given rHSP70 peptide - complex by SV injection twice at weekly intervals. Results The Dnak gene could be highly expressed in E. Coli as soluble protein. The expressing efficiency was 65% of the total cell protein and the soluble protein was 90% of the expressed protein. The rHSP70 - peptide complex could improve the immune protective function which had significant difference compared with controls (P

OBJECTIVETo observe effects of treatment from the lung and treatment from the intestine on the level of vasoactive intestinal peptide (VIP) in the lung and intestine of ulcerative colitis (UC) rats.
METHODSThe UC rat model was established in 52 rats by using rabbit intestine mucosa tissue allergen combined TNBS-ethanol model (with the model successful rate of 78.0%). Eight rats randomly selected from 40 successfully modeled rats and 8 of 16 rats from the normal group were recruited as the model group and the normal control group before intervention (at week 0). The rest 32 successfully modeled rats were randomly divided into the model group, the Western medicine treatment group (salazosulfapyridine), the treatment from lung group (Huangqi Jiegeng Decoction), and the treatment from intestine group (Huangqi Huanglian Decoction), 8 in each group. Rats in each treatment group were administered with corresponding medication 8 times the dose of a 60 kg adult human. Another 8 normal rats were recruited as the normal group. Equal volume of pure water was given to rats in the model group and the normal group by gastrog avage, once per day. Contents of VIP in the lung tissue and the intestinal tissue were detected at week 0 and 4 after 4-week consecutive intervention. Pathomorphological changes of the lung tissue and the colon tissue were observed under light microscope.
RESULTSCompared with the normal control group at week 0, evenly distributed diffuse inflammation could be seen in the pulmonary interstitial tissue; the bronchial wall was thickened; a huge amount of infiltration surrounded bronchi and blood vessels; a large area of necrosis of intestinal mucosa and inflammatory cell infiltration could also be seen in the model group. Pathological injuries of the lung and the colon were more alleviated in each treatment group than in the model group at the same time point. Compared with the normal control group at the same time point, VIP contents in the lung tissue significantly decreased in the model group at the end of week 4 (P<0.05); VIP contents in the colon tissue significantly increased in the model group at the end of week 0 and 4 (P <0.05). Compared with the model group, VIP contents in the lung tissue significantly increased in the Western medicine treatment group and the treatment from lung group at the end of week 4 (P<0.01); VIP contents in the colon tissue significantly decreased in the treatment from lung group and the treatment from intestine group (P<0.05, P<0.01).
CONCLUSIONTreatment from the lung and treatment from the intestine showed predominant advantage in improving local inflammation of the lung and the intestinal tract, alleviating pathological injuries, promoting repair of injuries through regulating VIP contents in the lung tissue and the colon tissue.

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.

OBJECTIVETo explore Chinese medical theory of Fei and Dachang being interior-exteriorly correlated by observing changes of inherent immune response and acquired immune response in the lung tissue and the intestinal tissue of ulcerative colitis (UC) model rats and the intervention of Chinese compounds (CM).
METHODSSeventy rats were randomly divided into 5 groups, i.e., the normal control group (n = 10), the model group (n = 15), the treatment 1 group (n = 15, treated from Fei), the treatment 2 group (n = 15, treated from the intestine), and the Western medicine (WM) group [n = 15, treated with Sulfasalazine (SASP). Except those in the normal control group, the UC rat model was prepared by allergizing colon mucosa combined with TNBS-alcohol (50%) enema, and then intervened by medication (treated with CM complex prescription of treatment from lung, CM complex prescription of treatment from intestine, and SASP). After intragastric administration for 4 weeks, rats were sacrificed and samples taken. The expression of tumor necrosis factor α (TNF-α) and IL-8 contents in the lung tissue, the intestinal tissue, and the serum were detected by radioimmunoassay. Serum MedCAM-1 contents were detected using ELISA. Changes of the expression of Toll-like receptor 4 (TLR4), nuclear factor κB (NF-κB), neutrophil migration inhibition factor (MIF), mucosal addressin cell adhesion molecule-1 (MadCAM-1) mRNA in the lung tissue and the intestinal tissue were detected by real time PCR.
RESULTSCompared with the normal control group, the expression levels of TNF-α, TLR4 mRNA, IL-8, MIF mR- NA, and MadCAM-1 mRNA obviously increased in the model group (P < 0.01). Compared with the model group, the expression levels of TNF-α, TLR4 mRNA, IL-8, MIF mRNA, and MadCAM-1 mRNA obviously decreased in the treatment 1 and 2 groups (P < 0.01). The expression of MadCAM-1 mRNA in the intestinal tissue was obviously higher in the model group than in the normal control group (P < 0.01), while the expressions of TNF-α and NF-κB mRNA was obviously lower in the model group than in the normal control group (P < 0.05, P < 0.01). Compared with the model group, the expression of MadCAM-1 mRNA all significantly deceased in each treatment group (P < 0.05, P < 0.01). Serum TNF-α contents were higher in the model group than in the normal control group (P < 0.05). Compared with the model group, serum TNF-α contents could be lowered in the treatment 1 and 2 groups (P < 0.05, P < 0.01).
CONCLUSIONSThe main mechanisms of the intestinal injury in this UC model might be related with activation of acquired immune response, accompanied with lowered functions of inherent immune response. The main mechanisms of the lung injury in this UC model might be related acquired immune response and inherent immune response. Treatment from Fei and treatment from Dachang both could obviously improve the immunodissonance of Fei and Dachang, indicating the special relation between the lung tissue and the intestinal tissue, thus providing experimental evidence for Chinese medical theory of Fei and Dachang being interior-exteriorly correlated.
