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 analyze the impact of extraction and nonextraction in soft tissue profile repair. METHODS: Databases of CNKI, Wanfang, VIP Chinese Periodical Database, CBM, Medline (ovid) and Science direct had been searched for studies of soft tissue profile after orthodontic treatment with and without extractions published in recent decade, with orthodontics, corrective, tooth extraction, soft tissue profile as key words. Hand searching was also done to obtain any further information about the studies. Meta analysis was used to comprehensively quantitatively analyze the upper (lower) lip with esthetic plane and soft tissue plane before and after extraction and nonextraction treatment. According to homogeneity test, fixed effect model and random effect model were adopted to calculate weighted mean difference (WMD) and 95% confidence interval (95% Cl).Revman 5.0 was used for data management. RESULTS: Five studies with 356 patients were included. Homogeneity test showed that lower lip-esthetic line and lower lip-soft tissue line Ⅰ~2 < 50%, without heterogeneity, so fixed effect model was adopted. Upper lip-esthetic line and upper lip-soft tissue line were more than 50%, indicating heterogeneity, so random effect model was adopted. Result of meta-analysis showed that, the WMD value and 95% Cl of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line has statistically significance. CONCLUSION: The extraction treatment significantly decreased the distance of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line.

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 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 compare the consistence and difference between the assay results of the second generation of Tg (Tg Ⅱ) and the first generation of Tg (Tg Ⅰ) immunoassay,as well as to evaluate the impact of Tg Ⅱ on the clinical management of thyroid diseases.Methods Serum samples of 249 patients (30 with benign thyroid disorders and 219 with DTC;64 males and 185 females,average age 43.0 years)were collected and assayed by Tg Ⅱ and TgⅠ kits simultaneously.The measuring ranges of TgⅠ and TgⅡ were 0.10-1 000.00 μg/L and 0.04-500.00 μg/L,respectively.Data were analyzed by the Wilcoxon rank sum test and Spearman correlation analysis using IBM SPSS 19.0.Results The assay results of TgⅡ and TgⅠ strongly correlated (rs =0.979,P＜0.05).However,the median value of TgⅡ (2.31 (0.06-13.17) μg/L) was lower than that of TgⅠ(3.63(0.41-16.84) μg/L)(z=-13.25,P＜0.001).The difference between Tg Ⅱ and Tg Ⅰ got bigger when TgⅠ value decreased more.TgⅡ values were 11.09％ lower than TgⅠ (5.61(1.07-26.39) μg/L) vs 6.31(2.07-33.93) μg/L;z=-4.78,P＜0.05) in 30 patients with benign thyroid disorders and 37.71％ lower (2.18(0.07-7.47) μ.g/L) vs 3.50(0.39-10.18) μg/L;z=-9.02,P＜0.001) in 108 DTC patients without 131 Ⅰ treatment.But the above changes had no influence on clinical diagnosis and treatment.In the 71 DTC patients post 131Ⅰ treatment with low TSH and normal TgAb,there were 3 cases with TgⅠ＞1.0 μg/L but TgⅡ＜1.0μg/L,and 12 cases with TgⅠ＞0.1 μg/L but TgⅡ＜0.04 μg/L.Conclusions Serum TgⅡand Tg Ⅰ assay results are strongly correlated,though Tg Ⅱ value is slightly lower than Tg Ⅰ value.This difference may have no significant influence on the clinical diagnosis of thyroid diseases.However,TgⅡ may be better to evaluate the curative effect in some DTC patients post 131Ⅰ therapy.

Objective To investigate the prevalence and risk factors of postpartum depression among female immigrants at Tianhe district of Guangzhou. Methods A total of 2021 migrant women postpartum in three hospitals at Tianhe district of Guangzhou were screened with Center for Epidemiological Survey Depression Scale , (CES-D), Social Support Rating Scale(SSRS) and self-made related factors questionnaire from May to December, 2013. Results This study showed postpartum depression affected 18.31% of migrant women at Tianhe district of Guangzhou. Unconditional logistic regression analysis showed a significant correlation of PPD with birth place , residence time,newborn disease,fetus gender and household income (P < 0.05). Multivariate logistic regression analysis identified birth place,residence time,newborn disease,fetus gender as the risk factors for PPD,household income was negatively correlated with the incidence of PPD with OR value of 0.680;Compared with healthy female immigrants, the total score of social support rating scale,the score of objective support,subjective support and social utilization degree were significantly reduced respectively in female immigrants with PPD. Conclusion The prevalence of PPD was high at Tianhe district of Guangzhou,health education and comprehensive social support system should be offered in order to prevent PPD.
