Objective To investigate the clinical characterastics of uremia pruritus and the value of treatment by bacillus coagulans. Methods The clinical data of 312 patients with maintenance hemodialysis were collected. The incidence rate, clinical manifestation and correlation factors of uremia pruritus were analyzed. Then, 40 refractory pruritus patients were divides into 2 groups by random digits table, with 20 patients in each group. The patients in experiment group were treated by bacillus coagulans, and the patients in control group were given vitamin E. The relieve of pruritus in two groups was compared. Results In 312 patients, 158 patients didn′t have pruritus, 56 patients had mild pruritus, 68 patients had moderate pruritus , and 30 patients had severe pruritus. The levels of urea nitrogen, creatinine, calcium, ferroprotein in different degree of pruritus patients had no significant differences (P>0.05), but the levels of phosphorus, calcium-phosphorus product, immunoreactive parathyroid hormone (iPTH), C reactive protein (CRP), interleukin (IL)-1 and IL-6 increased with the severity of pruritus (P<0.05). Logistic regression analysis showed that the levels of CRP, IL-6, iPTH were risk factors for pruritus (P<0.01 or <0.05). The VAS scores of moderate and severe pruritus patients in experiment group after treatment were significantly decreased compared with that before treatment (P<0.05). The levels of CRP, IL-1 and IL-6 before and after treatment in control group had no significant differences (P>0.05). The levels of CRP, IL-1 and IL-6 after treatment in experiment group significantly decreased (P<0.05). The rate of pruritus was very high , and there was markedly positive correlation between pruritus and serium inorganic phosphorus、iPTH and CRP. Bacillus coagulans can alleviate pruritus. Conclusions On the basis of maintenance hemodialysis, bacillus coagulans can regulate the intestinal flora, alleviate inflammatory reaction, and help to release the symptom of pruritus.

Objective: To observe the effects of heat-sensitive moxibustion plus Chinese medication on serum inflammatory indicators, T-lymphocyte subsets, and serum microRNAs in patients with multiple myeloma after chemotherapy. Methods: Eighty-two patients with multiple myeloma who had terminated chemotherapy were divided into an observation group and a control group using the random number table method, with 41 cases in each group. The control group received symptomatic treatment of Western medicine plus oral Chinese medication Yi Shen Qiang Gu Tang (decoction for benefiting the kidney to strengthen bones), and the observation group received additional heat-sensitive moxibustion treatment. After the intervention, the following measures were observed, including clinical efficacy, symptom scores of traditional Chinese medicine (TCM), and tumor patient's quality of life (QOL) scores [including Karnofsky performance status (KPS) score, performance scale (PS) score, and tumor-specific QOL questionnaire score] alongside the serum inflammatory indicators [tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and interleukin-6 (IL-6)], and the relative expression levels of T-lymphocyte subsets (CD3+, CD4+, and CD8+) and serum microRNA-302 (miR-302), microRNA-140-5p (miR-140-5p), and microRNA-125a (miR-125a). Results: After treatment, the total effective rate was 85.4％ in the observation group, higher than 68.3％ in the control group (P<0.05). The observation group was superior to the control group in improving the serum inflammatory factor levels, TCM symptom scores, tumor patient's QOL scores, and the relative expression levels of T-lymphocyte subsets and serum miR-302, miR-140-5p, and miR-125a, and the between-group differences were statistically significant (P<0.05). Conclusion: Heat-sensitive moxibustion plus Chinese medication can lower the serum inflammatory factor levels, strengthen immune function, mitigate TCM symptoms, enhance QOL, and raise the expression levels of serum miR-125a, miR-140-5p, and miR-302 in multiple myeloma patients after chemotherapy.

OBJECTIVE:To study the vasodilatation effects of the alcohol extract from Uighur medicine Ziziphora clinopodioi-des(EEZ)on isolated rat thoracic aorta vessel rings. METHODS:Isolated rat thoracic aorta vessel rings were prepared. There was a group with intact vessel ring endothelium and a group with vessel ring endothelium removed in the test. After preshrinking the ves-sel rings with phenylephrine(PE),EEZ of 100,300,500,700,900 and 1 100 mg/L was added gradually,concentration-vasodila-tation curve was drawn and maximal vasodilatation rate (Emax) and median effective concentration (EC50) were calculated. For the group with vessel ring endothelium removed,after the vessel ring was pretreated with EEZ at EC50 in calcium-free solution or calci-um-free high-potassium solution,CaCl2 of 0.4,0.8,1.2,1.6,2.0 and 2.4 mmol/L was added gradually,and calcium concentra-tion-tension curve was drawn;following the pretreatment of the vessel ring with EEZ at EC50,1 μmol/L PE was added and shrink tension was recorded and vasoconstriction percentages was calculated. RESULTS:EEZ had vasodilatation effect on the vessel ring preshrunk with PE in a concentration and smooth muscle-dependent manner. The group with intact vessel ring endothelium and the group with vessel ring endothelium removed respectively had Emax of (58.18 ± 16.23)% and (73.54 ± 17.21)%,and EEZ EC50 of 773.27 mg/L. For calcium-free high-potassium solution,EEZ could cause the calcium ion-vasoconstriction curve to move to the right obviously;for calcium-free solution,EEZ could inhibit the vasoconstriction caused by PE. CONCLUSIONS:EEZ has vasodi-latation effects by a mechanism which may be related to inhibiting calcium influx and intracytoplasmic calcium release through the inhibition of voltage-dependent calcium channels(VDCCs),and thus interfering intracytoplasmic calcium ion balance.

Objective The immature platelet fraction (IPF) could be detected quantificationally in Sysmex XE-2100 with the software of XE-pro and IPF master.The study aimed to perform the methodological evaluation of IPF detection and investigate the clinical significance for the monitoring for bone marrow hyperplasia in cancer chemotherapy patients.Methods The high-level, middle-level and low-level whole blood samples were randomly chosen for detection repeatly 20 times to obtain interrun coefficient of variation (CV) for evaluation of the precision and reproducibility. Integrated quality controls were determined for continuous 20 days to obtain intrarun CV, and the stability and carryover was investigated.Furthermore, the correlation between results from Sysmex XE-2100 and results from flow cytometry was assessed.182 healthy subjects and 130 cancer patients undergoing chemotherapy were selected and the latter were divided into two groups according to platelet counts after therapy, one was normal PLT group, the other was decreased PLT group.The IPF of either group was measured and was compared with each other.Results The precision of IPF for high-level, middle-level and low-level were 4.71%, 4.33% and 4.95%, respectively, they were less than 5%.The interrun CV of IPF detection for middle-level and low-level were less than 5%.The interrun CV of IPF detection for high-level were less than 10%.The carryover ranged from 0.6% to 2.7%,and the average rate was 1.2%.A good correlation for IPF detection was shown between results from Sysmex XE-2100 and flow cytometry(r = 0.880 9,P ＜ 0.01).Regarding clinical utility of IPF detection in treatment monitoring for chemotherapy effect, the median of IPF levels in decreased PLT group, normal PLT group,control group were 14.45% ,7.35% and 15.68%, respectively.There was significant difference among the three groups (H =49.032,P ＜0.01 ).The IPF level was higher in decreased PLT group than normal PLT group (t = -5.681, P ＜ 0.O1 ), and was lower in normal PLT group after chemotherapy than the control group (t = -6.662 ,P ＜0.01 ).Conclusions The determination of IPF by the Sysmex XE-2100 owns high precision and good stability. IPF is an effective marker for evaluation of thrombopoietic condition in the cancer chemotherapy patients.

Objective To investigate the effect of advanced oxidation protein products (AOPPs) on human renal tubular epithelial cells(HK-2) autophagy.Methods HK-2 cells were stimulated with AOPPs.RT-qPCR and Western blot were used to determine the expression of autophagy related protein LC3-Ⅱ/LC3-Ⅰ,Beclin1 and p62;Western blot was utilized to examine the activation of p38 MAPK pathway.Then p38 MAPK inhibitor (SB203580) was added and co-processed with AOPPs.The change of autophagy was observed Also,autophagy inducer rapamycin was added and co-processed with AOPPs.RT-qPCR and Western blot were used to detect the expression of cell cycle inhibitory protein p27.The cell total protein level was detected by the bicinchoninic acid (BCA) method.The hypertrophy change was observed.Results AOPPs down-regulated the expression of LC3-Ⅱ/LC3-Ⅰ and Beclin1,up-regulated expression of p62 and activated p38 MAPK pathway;in comparison with the AOPPs alone treatment group,the expression of LC3-Ⅱ/LC3-Ⅰ and Beclin in the SB203580 co-processing group was increased,while p62 was decreased;the p27 expression and cells total protein in the sirolimus co-processing group were down-regulated.Conclusion AOPPs inhibits the autophagy of HK-2 cells by activating p38 MAPK pathway and the autophagy inhibition participates in HK-2 cell hypertrophy.

Objective To discuss whether it is necessary to integrate metabolic indices into diagnosis of polycystic ovary syndrome(PCOS).Methods Taking ESHRE /ASRM diagnosis standard as gold standard,the case group composed of 51 women with PCOS and the control group composed of 47 women without PCOS were selected.By using classification tree C5.0,significant variables chosen by single factor analysis were used to establish a new diagnostic model which combined reproductive indices and metabolic indices.The validity and reliability of the new diagnostic model by using ROC curve analysis were evaluated.Finally,the consistence and difference between the new diagnostic model and the gold standard were analyzed.Results Single factor analysis chose 13 significant variables. ROC analysis showed an area under the curve of 0.930(P =0.000)and the optimal cut -off point was 0.190 with a sensitivity of 94.10%,a specificity of 91.50% and a consistency of 92.86%,which told us the new diagnostic model had superior validity and reliability.The two diagnostic methods had excellent consistence (Kappa =0.857,P =0.000)and there was no statistically significant difference (P =1.000).Conclusion Considering that whether metabolic indices are integrated into diagnosis of PCOS doesn′t change the diagnosis result,and it is unnecessary to integrate metabolic indices into diagnosis of PCOS.

Objective To discuss the relationship between Hp eradication effect and TCM syndrome types, and provide basis for improving clinical Hp eradication rate of TCM. Methods TCM syndrome types of 922 Hp-positive patients were distinguished. After treatment by the quadruple chemotherapy, the effect of Hp eradication of different TCM syndrome type was analyzed. Results In 922 Hp infectors, Hp eradication effect in different TCM syndrome type from low to high was as follows:spleen-stomach deficiency-coldness, cold-heat complication, stomach-yin deficiency, congestion of stomach collaterals, hyperactive liver-qi harmful to stomach, liver-stomach heat, spleen-stomach dampness-heat, with significant difference (P<0.05). A total of 623 patients were discriminated as excessive syndrome (including spleen-stomach dampness-heat, liver-stomach heat, hyperactive liver-qi harmful to stomach and congestion of stomach collaterals), and its eradication rate was 82.5%. A total of 244 patients were discriminated as deficient syndrome (including spleen-stomach deficiency-coldness and stomach-yin deficiency), and its eradication rate was 58.6%. The difference between excessive syndrome and deficient syndrome was statistically significant (P<0.05). Hp eradication effect among different TCM syndrome types of excessive syndrome had statistical difference (P<0.05), while that of deficient syndrome had no statistical difference (P>0.05). Conclusion The eradication rate of Hp infection was different in patients with different TCM syndrome types, which in deficient syndrome is obviously lower than in excessive syndrome.

Objective To investigate the effect of Tongqiao Yinao decoction ( TYD) on postoperative cogni-tive dysfunction in elderly patients and its underlying mechanisms .Methods 100 anesthetic patients for orthopedic surgery were randomly divided into the TYD-treated group and control group ,50 patients in each group .In TYD-trea-ted group,patients received 150mL TYD orally,twice daily for constitutive 15 days,beginning from the day of admis-sion in addition to conventional symptomatic and supportive treatment .While patients in control group received no TYD.Mini-mental state examination ( MMSE) was used to evaluate the patients′cognitive function before and after anesthesia.Meanwhile,blood samples of patients were also collected to test the expression levels of IL -6.Results There was no significant difference between the two groups before operation .However ,TYD-treated patients had signif-icantly lower incidence rate of POCD than the controls ( 20% in the control group , and 12% in the TYD-treated group;χ2 =4.332,P=0.037) 7 days after operation.The incidence rates of POCD in the TYD-treated group and control group were 30%and 38%1 day after operation ( P>0.05),28% and 20% 3 days after operation ( P>0.05),respectively.Compared with that before operation ,the blood levels of IL-6 in the two groups significantly increased 3 days after operation (control group,t=2.412,P=0.009;TYD-treated group,t=1.429,P=0.039).In contrast to the control group,the level of IL-6 in TYD-treated group declined to the baseline (the control group,t=0.851,P=0.049;TYD-treated group,P=0.404).Interestingly,compared with the controls,the TYD-treated patients had a significant lower level of IL-6 after operation (t=1.198,P=0.035).Furthermore,Pearson correlation analysis showed that change of IL-6 level in blood was negatively correlated with MMSE score (r=-0.782,P=0.022). Conclusion TYD can improve postoperative cognitive dysfunction in elderly patients ,presumably through decreasing the level of IL-6 in blood.

Methods:We collected peripheral blood from 47 untreated HIV infected individuals and 31 healthy controls,and analyzed the expression of Annexin-V,Ki-67,HLA-DR and other surface molecules in NKT like cells by flow cytometry. Results:The NKT like cell percentage of untreated HIV infected group was (3. 03±1. 61)%,the NKT like cell percentage of normal control group was (8. 30±7. 42)%,the percentage of NKT like cells in HIV infected individuals was significantly lower than the healthy controls ( P<0. 05 );the NKT like cell HLA-DR expression of untreated HIV infected group and normal control group were (5. 40±4. 10)% and (0. 89±0. 83)%,the NKT like cell Annexin-V expression of untreated HIV infected group and normal control group were (30. 21±13. 15)% and (5. 40±8. 05)% ,and the activation and apoptosis of NKT like cells was significantly higher after HIV infection compared with health individuals (P<0. 001,P<0. 01),the degree of activation was negatively correlated with CD4 count (r=-0. 885 7,P<0. 05);and the NKT like cell Ki-67 expression of untreated HIV infected group and normal control group were (11. 15±4. 76)% and (27. 63±18. 31)%,the proliferation ability was significantly lower after HIV infection compared with healthy controls(P<0. 05). Conclusion:HIV infection can significantly reduce the number of NKT like cells and its ability to proliferate,and increase its ability to activation and apoptosis.

OBJECTIVE: To investigate the effect of dxamethasone (DEX) on the expression of Tregs in allergic rhinitis (AR) mice, and explore the mechanism of glucocorticoid in the treatment of AR. METHOD: AR murine model was established by sensitization and challenge with OVA, besides intervention treatment with DEX was carried out in AR model. The behavior observation was used to evaluate the improvement effect of DEX on AR symptoms. The morphological characteristics of nasal tissues were observed by HE staining after fixation and decalcification. The mononuclear cells were obtained by grinding spleens, and the total RNA was extracted for reverse transcriptase polymerase chain reaction to investigate the level of mRNA expression of Foxp3. The changes of CD4+ Foxp3+ Tcells in spleen of mice were analyzed by flow cytometry. RESULT: BALB/c mice received OVA sensitization followed by OVA intranasal challenge, the frequencies of sneezing and nose-scratching increased significantly in AR group (44. 50 ± 5. 61 and 72. 94 ± 8. 76) compared with control group (12. 68 ± 1. 87 and 26. 76 ± .2. 89), P<0. 01; The frequencies decreased significantly in DEX group (26. 04 ± 3. 93 and 56. 79 ± 5. 64), P< 0. 05 compared with AR group. The continuity of nasal mucosa ciliated columnar epithelium in AR group was destroyed and appeared to be repaired in DEX group. Inflammatory cells infiltration was also markedly decreased by DEX treatment. The proportion of CD4+ Foxp3+ T cells in AR group (3. 89 ± 0. 39)% decreased, P<0. 01 vs control group (4. 63 ± 0. 15) %. DEX treatment induced production of Tregs (6. 89 ± 0. 49)%, P<0. 05 vs control group. DEX significantly increased the expression of Foxp3 mRNA (P<0. 05) compared with AR and control group. CONCLUSION DEX reduce upper airway allergic inflammation effectively, which may be mediated by promoting the expression of Foxp3 and inducing the amplification of Tregs in vivo.
