Objective To investigate the influence of LNG-IUS placement on endometrial thickness, recurrence rate and complications of patients with endometrial polyps and moderate anemia after TCRP. Methods 140 patients with endometrial polyps and moderate anemia were chosen from January 2014 to January 2016 and randomly divided into control group (70 patients) with TCRP used alone and observation group (70 patients) with LNG-IUS placement after TCRP; the endometrial thickness, hemoglobin levels and PBAC score before and after treatment, the recurrence rate and the complication incidence of both groups were compared. Results The endometrial thickness after treatment of observation group were significantly less than control group before the treatment (P < 0.05). The hemoglobin levels and PBAC score after treatment of observation group were significantly better than control group before the treatment (P < 0.05). The recurrence rate of observation group were significantly lower than control group (P < 0.05). There was no significant difference in the complication incidence between the two groups (P > 0.05). Conclusion LNG-IUS placement in treatment of patients with endometrial polyps and moderate anemia after TCRP can efficiently reduce the endometrial thickness, decrease the uterine bleeding amount, prevent the long-term recurrence and not increase the complications incidence.

Asymmetric dimethylarginine(ADMA) is an endogenous inhibitor of nitric oxide synthases(NOS),which is a risk marker of cardiovascular endothelial dysfunction.Recent studies found that ADMA was a predictor not only for acute cardiovascular disease,but also for critical illness and mortality.Studies have found that exogenous ADMA altered lung function and induced apoptosis in animal experiments and vitro experiments.The levels of plasma ADMA significantly increased in children with hypoxia,PPHN,brain damage,and preterm infants who required mechanical ventilation.ADMA could be a independent risk factor to predict neonatal complications and death.

Objective To investigate the distribution features of upper limb involved nerves in patients with diabetic peripheral neuropathy (DPN).Methods The sensory nerve conduction velocity (SCV)and amplitude(SNAP),motor nerve conduction velocity(MCV)and amplitude(CAMP)of median,ulnar and radial nerves were examined in 98 DPN patients (DPN group) and 32 normal controls(NC group).The distributive ferture of involved upper limb nerves in DNP patients were analysed.Results (1) Comparing to NC group,the SCV and MCV of median,ulnar and radial nerves in DPN group were significantly slower (P

Pulse-taking is the most specific diagnostic method of TCM.Its significance has been recognized by ancient and modern doctors.However,at present the application and spread of pulse-taking is limited.In this paper,the author made detailed explorations of literatures and studies the value of pulse condition in guiding syndrome differentiation of liver diseases.The study shows abnormal pulse in left guan and taut pulse in cunkou location both suggest the liver is disordered.We can judge the location of diseases through pulse condition.This exploration shows pulse-taking plays important role in syndrome differentiation.But there is one thing should be paid more attention,pulse condition should be integrated with other symptoms,that will be reliable in guiding diagnosis.

Objective To investigate the differential expression of microRNAs(miRNAs) in transplanted kidney undergoing chronic rejection by the technique of RNA microarray.Methods Four biopsy specimens from transplanted kidney undergoing chronic rejection were harvested as test group(CR),and 3 biopsy specimens were obtained from normal renal cortex as normal control group(NC).Total RNA of each sample was extracted using Trizol reagent.miRNAs were isolated and differential expression of miRNAs were screened by miRNA array analysis.The results of miRNA array were validated by RT-PCR.The quantity and quality of all the RNA samples were checked by gel electrophoresis and absorbance at A260/280,respectively.Results It was confirmed that the isolated RNA was of appropriate quality.The results of miRNA array analysis showed that there were 63 differential expression miRNAs in CR group,of which 35 were up-regulated and 28 down-regulated.There were 9 differential expression miRNAs which distributed in 3 gene clusters: 14q32.31,22q11.21 and xq27.3.The miRNAs hsa-miR-637,hsa-miR-648 and hsa-miR-516-5p were randomly selected for relative quantification by real-time PCR.It was showed that the expression ratios of hsa-miR-637,hsa-miR-648 and hsa-miR-516-5p in AR/NC,when detected by RT-PCR,were 0.034,2.670 and 7.846,while the ratios were 0.035,2.660 and 7.857 when analyzed by miRNAs array.The results from two methods were not significantly different,so the method of miRNAs array was reliable.Conclusions It is notable that the differential expression of miRNAs existed in the transplanted kidney undergoing chronic rejection.miRNAs might be helpful in protecting the patients undergoing kidney transplantation against chronic rejection.

Mild cognitive impairment (MCI) is considered as an intermediate clinical state between normal aging and Alzheimer’s disease (AD). The cognitive function and life ability of patients are normal, which have not met the criteria of AD. MCI is considered to be an earlier stage of AD. The clinical effects of AD in the middle or late stage are unsatisfactory. Therefore, studies on MCI have become the hot research areas both at home and abroad. The therapy of MCI is similar to AD. The treatment effect is uncertain. Hence, the understanding and treatment of MCI by TCM reflected TCM features. This article reviewed on TCM understanding of MCI, TCM syndrome differentiation criteria and TCM treatment methods of MCJ. Thus, it was aimed to further understand the dynamic of MCI in order to provide references for improving TCM clinical effects and reducing the incidence of AD.

Objective To establish a cell line with repressed expression of p53 by transfecting a plasmid construct expressing short hairpin RNA(shRNA)targeting p53 into human skin fibroblasts(HSFs),and to evaluate the effect of repression of p53 expression on the senescence in HSFs.Methods The eukaryotic expressing plasmid pGCsi-p53 containing shRNA targeting p53 gene was transfected into HSFs with lipofectamine.Subsequently,the cells were selected by G418,and resistant cell clones were chosen and expanded.Reverse transcription-PCR and real time fluorescence-based quanitative PCR were performed to determine the expression of p53 gene,and Western blot to detect the expression of p53 protein in HSFs.The senescence in HSFs was evaluated by SA β-gal staining,and cell proliferation by methyl thiazolyl tetrazolium(MTT)assay.Results A HSF clone with repressed expression of p53 was established successfully.The expressions of p53 mRNA and protein were downregulated in transfected HSFs compared with untransfected HSFs(0.09 ± 0.03 vs.0.32 ± 0.04,0.11 ± 0.04 vs.0.84 ± 0.05,both P ＜ 0.01).The percentage of senescent cells was 13.47％ ± 1.01％ in the transfected HSFs,significantly lower than that in untransfected HSFs(18.10％ ± 0.66％,P ＜ 0.05).As MTT assay showed,the proliferation was accelerated in transfected HSFs compared with untransfected HSFs(P ＜ 0.05).Conclusions The repression of p53 expression decelerates the senescence in HSFs,but promotes the proliferation of HSFs.

Objective To characterize the alteration in peripheral blood endothelial progenitor cells (EPCs) of patients with systemic lupus erythematosus (SLE).Methods Venous blood samples were obtained from 82 female patients with SLE aged (35 ± 10) years and 50 healthy female controls aged (35 ± 13) years.ACL 9000 automated coagulation analyzer was used to determine the level of Von Willebrand factor antigen (vWF Ag).Flow cytometry was performed to detect peripheral blood EPCs and circulating endothelial cells (CECs).Analysis of variance was performed to assess the differences in these parameters between patients with active and stable SLE and the controls,and Pearson correlation analysis was conducted to evaluate the relationship between these parameters.Results The number of CD34+ cells,CD133+ cells and CD34+CD133+cells per 200 000 peripheral blood mononuclear cells was 35.4 ± 16.7,86.5 ± 32.1 and 361.3 ± 176.4 in patients with active SLE,significantly higher than that in the patients with stable SLE (17.1 ± 10.9,28.7 ± 21.5,107.2 ±44.3,respectively,all P ＜ 0.01)) and the controls (13.8 ± 9.6,11.2 ± 5.5,92.3 ± 50.5,respectively,all P ＜0.01).The patients with active SLE exhibited an elevated level of vWF Ag (438.9％ ± 205.3％ vs.130.2％ ±51.5％,P ＜ 0.01),an increased number of EPCs (361.3 ± 176.4 vs.107.2 ± 44.3,P ＜ 0.01) but a similar number of CECs (127±51 vs.118 ± 39,P ＞ 0.05) per 200 000 peripheral blood mononuclear cells compared with the healthy controls.No significant differences were observed in these parameters between the patients with stable SLE and the controls (all P ＞ 0.05).The number of EPCs was positively correlated with the level of vWF Ag (r =0.67,P ＜ 0.01),but uncorrelated with the number of CECs (P ＞ 0.05) in patients with active SLE.Conclusions The quantity of EPCs in peripheral blood is closely correlated with the level of the vascular injury marker vWF Ag,hinting that the number of EPCs can serve as a useful marker of disease severity.

Objective To explore the expression level of CD4+ CD25+ CD127low-regulatory T cells (Treg) in the peripheral blood of hepatitis B virus (HBV)-infected individuals,and its association with liver pathology.Methods Thirty-five HBV-infected individuals and 20 healthy controls were enrolled.The frequencies of peripheral blood CD4+ CD25+ CD127low/-Treg were detected by flow cytometry.HBV-related serological tests as well as ultrasound-guided liver biopsies were performed in HBV-infected individuals.The two groups were compared by t test.Spearman and Pearson correlation analyses were performed.Results The alanine aminotransferase (ALT) level of HBV-infected individuals was (34.57 ± 15.36) U/L,with 25 subjects of ALT＜40 U/L.Twenty subjects were hepatitis B e antigen (HBeAg) positive,and 15 were HBeAg negative.The frequency of the peripheral blood CD4+ CD25+ CD127low/-Treg in HBV-infected individuals was (5.59 ±1.50)％,which was significantly higher than that in healthy controls [(4.85±0.95) ％ ; t=2.191,P=0.033].The level of peripheral blood CD4+ CD25-CD127low/-Treg was positively correlated with HBV viral load (r=0.495,P=0.003).Thirty-one subjects had liver inflammatory score ≤2,with a peripheral blood CD4+ CD25+ CD127low/-Treg level of (5.80 ± 1.44) ％,which was significantly higher than that of the rest 4 subjects who had liver inflammatory score ＞2 [(4.00±0.77)％; t=2.425,P=0.021].Twenty-four subjects had liver fibrosis score ＜2,with a peripheral blood CD4+ CD25+ CD127low/-Treg level of (6.00±1.44) ％,which was significantly higher than that of the rest 11 subjects who had liver fibrosis score ≥ 2 [(4.70 ± 1.24)％; t =2.559,P＝0.015].The expression of CD4 + CD25 +CD127low/-Treg in peripheral blood was inversely correlated with liver inflammation (r=-0.539,P=0.001) and fibrosis (r =-0.488,P =0.003) in HBV-infected individuals.Conclusions CD4+ CD25+ CD127low/-Treg is associated with chronic condition and liver damage of hepatitis B.It may play an important role in occurrence,development and prognosis of the disease.
