ABSTRACT
Objective To evaluate the diagnostic value of these alternant indexes by compare the results of routine blood test of early herpes zoster(HZ),acute cholecystitis and acute myocardial infarction patients.Methods According to some inclu-sion and exclusion criteria,78 HZ patients,59 acute cholecystitis and 51 acute myocardial infarction patients from October 2013 to March 2017 were included.The receiver operator characteristics(ROC)were used to evaluate the diagnostic value of the blood corpuscle indexes.Results White blood cell count(WBC),blood platelet count(PLT)and neutrophilic granulo-cyte percentage(NE%)of HZ patients were lower than the acute cholecystitis and acute myocardial infarction patients(P<0.001).Lymphocyte percentage(LYM%)and monocyte percentage(MO%)were higher than the others'.The NE% index had a certain diagnostic value(AUC=0.848,95%CI:0.792~0.905).There was a highest specificity in LYM% index(spe-cificity=0.963).Conclusion There were some clinical significance of routine blood cell count results on the early HZ diag-nosis,which can reduce the missed diagnosis and misdiagnosis rate of an early diagnosis herpes zoster.
ABSTRACT
Objective To evaluate the clinical effect of the homemade traditional Chinese medicine bathing prescription combined with Thymalfasin and Isotretinoin treatment for Verruca Plantaris.Methods A total of 120 patients with Verruca Plantaris were randomly divided into 3 groups according to the random number table method (each group 40). The drug therapy group was given Thymalfasin and Isotretinoin to treatment; and the Chinese medicine washing group was given traditional Chinese medicine wash-out on the basis of drug therapy; and the physical therapy group was given liquid nitrogen freezing treatment on the basis of drug therapy. All the groups were treated 12 weeks and follow-up 3 months. Four weeks were a course, and a total of 3 courses. After the treatment, the symptom grading scores (number of skin lesions, the size of skin lesions, the degree of pain and the quality of life) was compared, and the clinical effect rate was evaluated and the recurrence rate was observed.Results Twelve weeks after treatment, Chinese medicine washing group total effective rate was 97.5% (39/40), drug treatment group 87.5% (35/40), and physical treatment group 90.0% (36/40). The Chinese medicine washing group total effective rate was superior to the drug therapy and physicaltherapy groups (Z values were -3.463,-3.122,P values were 0.001, 0.002). after treatment, the number of lesions scores (2.0 ± 1.1 vs. 2.8 ± 1.5, 2.7 ± 1.6,F=3.787), the size of the lesion scores (2.3 ± 1.7 vs. 3.2 ± 1.3, 3.1 ± 1.3, F=4.657), pain degree and the quality of life scores (0.4 ± 0.5 vs. 1.0 ± 1.2, 1.0 ± 1.0,F=5.353) in the Chinese medicine washing group were significantly higher than those in the drug therapy and physical therapy groups (P<0.01). After follow-up period, the recurrence rate of Chinese medicine washing group was 10.3% (4/39), the drug treatment group 25.7% (9/35), the physical therapy group 41.7% (15/36). The difference among 3 groups was statistically significant (Z=-3.188,P<0.01).Conclusions The traditional Chinese medicine combined with Thymalfasin and Isotretinoin could reduce the number of skin lesions, narrow the range of skin lesions and reduce the degree of pain, and improve the quality of life.
ABSTRACT
Objective To investigate the mechanism of recombinant human bone morphogenetic protein-2(rhBMP-2)in repairing hematopoietic injury in mice irradiated with γ-ray.To prepare SRY gene probe and study the effect of rhBMP-2 in repairing hematopoietic injury in mice by in situ hybridization.Methods Twenty-two BALB/c female mice were randomly divided into the irradiated group and BMP treated group,respectively.Bone marrow cells of normal male mice were transplanted into 22 female mice post-irradiation to 8.5 Gy of 60 Co γ rays.The left femurs of the survived female mice were re-irradiated with 9 Gy 14 days later.Mice in BMP treated group were given rhBMP-2 20 mg/kg while those in control group were treated with 0.9% saline by intraperitoneal injection every day for 6 days.These mice were killed 14 days later and paraffin sections of femurs were made.The SRY gene was detected with in situ hybridization.Results There were more positive blots in the left femurs of the mice in irradiated group than those in BMP treated group(T=155.0,P＜0.05).The number of positive blots between the left femurs of the mice in irradiated group and the right femurs of the mice in two groups was not significantly different(T=92.0,78.5,P＞0.05).The number of positive blots in the left femurs of the mice in BMPtreated group was significantly less than those in the right femurs of the mice in two groups(T=155.0,55.0,P＜0.05).Conclusions No donor cell of male mice was detected in the left femurs of BMP treated group,suggesting that rhBMP-2 promoted the restoration of residuary bone marrow cells.Thus,rhBMP-2 promotes the proliferation or differentiation of residuary mesenchymal stem cells,improves hematopoietic microenvironment and accelerates the hematopoietic restoration.
ABSTRACT
<p><b>BACKGROUND</b>Bone morphogenetic protein (BMP) is a member of the superfamily of transforming growth factor-beta. Recent studies show that it is an indispensable factor in hematopoiesis. To better characterize the effect of recombinant human BMP (rhBMP)-2 in hematopoiesis, we set out to determine whether rhBMP-2 could promote the proliferation of mesenchymal stem cells (MSCs) and increase the levels of hematopoietic cytokines in MSCs.</p><p><b>METHODS</b>2, 3-bis (2-methoxy-4-nitro-5-sulfophenyl)-5-((phenylamino) carbonyl)-2H-tetrazolium hydroxide (XTT), real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) were used to detect the effects of rhBMP-2 on the proliferation and hematopoietic cytokine levels of MSCs. In addition, MSCs marked with Hoechst33342 were transplanted into BALB/c mice by the intravenous route or intra-bone marrow transplantation, and cluster numbers were counted.</p><p><b>RESULTS</b>The XTT test revealed that rhBMP-2 significantly induced proliferation of MSCs in doses ranging from 10 ng/ml to 0.1 mg/ml in a dose-dependent manner. The experiments in vivo showed that there were more clusters of donor cells in bone marrow, spleen, liver and lung of the BMP group than those in the control group after both intra-bone marrow transplantation (P < 0.001, P < 0.001, P < 0.001, and P = 0.001, respectively) and intravenous transplantation (P < 0.001, P < 0.001, and P < 0.001 respectively). The results of real-time PCR and ELISA revealed that rhBMP-2 significantly increased mRNA expressions and protein levels of IL-6, IL-7, IL-11, G-CSF, M-CSF and SCF.</p><p><b>CONCLUSIONS</b>The treatment with rhBMP-2 promotes the proliferation of MSCs in vivo and in vitro and increases the levels of hematopoietic cytokines in MSCs, which may contribute to the improvement of hematopoietic function.</p>

ABSTRACT
Objective:To investigate the effects of oxymatrine(OM)on the apoptosis of human hepatoma HepG2 cells and its possible mechanisms.Methods:HepG2 cells were treated with different concentrations of OM.The proliferation inhibition was measured by MTT assay and the apoptosis of HepG2 cells were examined by Hochest staining method.Flow cytometry was used to analyze the cell cycle distribution and apoptosis rate.The expression of caspase-3,Bcl-2,Bcl-x_L and Bax proteins was assayed by Western blotting assay.Results:OM inhibited HepG2 cells growth in a time-and dose-dependent manner.After treatment with OM for 24 hours,some cells appeared typical apoptotic characteristics and the apoptosis rate was increased. Treatment with OM also increased caspase-3 activity and Bax expression in HepG2 cells,and decreased the expression levels of Bcl-2 and Bcl-x_L.Conclusion:OM can induce HepG2 cell apoptosis,which may be related to the down-regulation of PI3K/Akt signal pathway,suppression of Bcl-2 and Bcl-x_L activity,and activation of caspase-3.
ABSTRACT
Objective To study the survival, migration and distribution of allogeneic marrow stromal cells (MSCs) which were marked with fluorescence agent Hoechst 33342 in vitro and then transplanted into the mice with acute radiation injury, and to explore the hematopoietic reconstitution in allogeneic MSCs transplantation. Methods The bone marrow of murine femoral bone was washed out with DMEM, the cell suspension was gathered and centrifuged twice, and then the MSCs were cultured in vitro, marked with Hoechst 33342 at final concentration of 10?g/ml. 30 minutes later, the MSCs were gathered and transplanted into radiation injured mice via intravenous injection. Each mouse was injected with 2?105 MSCs. The distribution of marked MSCs was observed in heart, liver, spleen, lung and kidney of radiation injured mice at time points of 1w, 2w and 3w after MSCs transplantation. Results After being marked with Hoechst 33342, the nuclei of MSCs were in bright blue color. All mice of MSCs-transplant-group survived until execution, but three mice of Non-MSCs-transplant-group died during three weeks. Only a few marked MSCs were found in heart, liver, lung and kidney in the frozen section at each time point, but a large number of marked MSCs were found on the surface of spleen, and colonies were formed two weeks after introduction of MSCs. Conclusions Transplanted MSCs can not only survive in the irradiation injured mice, but also specifically migrate to the injured site, to participate in the reconstitution of hematopoiesis after acute radiation injury.
