Objective To investigate the expression and prognostic significance of P-JAK2, P-STAT3 and mutant p53 in cervical lesions. Methods A total of 153 cervical biopsies of patients from Gynecology Department, The Second Hospital of Tianjin Medical University were recruited during December 2013 to June 2015. Fifty-seven cases of squamous carcinoma of cervix (SCC), 36 cases of low grade intraepithelial neoplasia (LSIL), 30 patients with high grade intraepithelial neoplasia (HSIL) and 30 cases of normal cervix (NC) were included in the study. Gene chip method was used to detect high-risk hu-man papillpmavirus(HR-HPV)infection. Hematoxylin-eosin staining was used to make pathological diagnosis. Immunohis-tochemical assay was used for the detection of P-JAK2, P-STAT3 and mutant type p53 protein expression in cervical le-sions. Results (1) HR-HPV infection rate and P-JAK2 expression were significantly higher in SCC group than those of HSIL group, LSIL group and NC group (P<0.05). (2) The expression of P-STAT3 and mutant type p53 were significantly higher in SCC group than those of LSIL group and NC group (P<0.05). However, there was no significant difference between SCC group and HSIL group. (3) The positive expressions of P-JAK2 and P-STAT3 showed significant differences in different FIGO stages, histopathological grade, lymph node metastasis and HR-HPV infection in SCC group, respectively ( P<0.05). There were significant differences in the positive expression of mutant type p53 between different FIGO stages and HR-HPV infection (P<0.05). (4) There was positive correlation between P-JAK2, P-STAT3, positive expression of mutant type p53 and HR-HPV infection in SCC tissues (P<0.05). There was a positive correlation between P-STAT3, p53 expression and HR-HPV infection (P<0.05). There was a positive correlation between mutant p53 expression and HR-HPV infection (P<0.05). Conclusion P-JAK2, P-STAT3 and mutant p53 protein expression rates are high in SCC group than those of NC and SIL groups, which may be associated with HR-HPV infection, cervical cancer occurrence and progression.

OBJECTIVETo investigate the protective effect of soyasaponins on acute liver injury induced by D-galactosamine (GalN) and lipopolysaccharide (LPS) in mice.

METHODThe mice were randomly divided into five groups: the normal control, the model group, the silymarin (positive control) group, and soyasaponins high and low-dose groups. They were administered with drugs once every day for 7 days. At the end of the experiment, GalN and LPS were injected intraperitoneally to all of the groups except for the normal group to establish the acute liver injury model. The pathological changes were detected with hematoxylin & eosin (HE) staining, tumor necrosis factor-alpha (TNF-alpha) was detected by ELISA method, and the alanine aminotransferase (ALT), aspartate aminotransferase (AST), catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST), reduced glutathione (GSH), malondialdehyde (MDA), nitric oxide (NO), and the activation of Caspase-3 and Caspase-8 were detected by the colorimetric method.

RESULTSoyasaponins could reduce the activities of serum ALT and AST, the acute hepatic injury induced by GalN/LPS, serum TNF-alpha level, hepatic NO and MDA contents, and the Caspase-3 and Caspase-8 activations of liver tissues, and increase the hepatic CAT, GPx, GST and GSH levels.

CONCLUSIONSoyasaponins shows the protective effect on acute liver injury induced by GalN and LPS in mice, which may be related to its antioxidative ability and anti-liver apoptosis.

Objective To investigate the characteristics of renal hemodynamic and the esoteric prostacyclin(PGI2),thromboxane A2(TXA2)level in children with early Henoch-Schonlein purpura(HSP),and study the function of TXB_2/6-Keto-prostaglandin F(6-Keto-PGF_(1?))(T/K)numerus in early changes of kidney injury.Methods Children involved in the experiment were dicided into 3 groups.Thirty-one patients with HSP,divided into 2 groups according to routine urianlysis:children with HSP without renal damage group(n=16)and Henoch-Schonlein purpura nephritis(HSPN)group(n=15).Control group with 16 healthy children,their age and sex match with the other 2 groups.The urine of all children,including the children in control group,was sampled in 24 hours.The urinary production of the samples were kept in the freezer at-20 ℃.The radioimmunoassay was applied to determine the 6-Keto-PGF_(1?),TXB_2 quantitatively,and calculate the number of T/K.In the early morning the children accept the Doppler arteria renalis sonography with an empty stomach to determine the Vmax of the period of contraction of the arteria renalis the Vmin of diastolic phase and the resistent index(RI).SPSS 13.0 software was used to analyze the data.Results 1.The renal hemodynamic indicated a change of high velocity and resistance,the masculine rate(83.9%)was ob-viously higher than that in routine urinalysis(48.4%)(?2=5.79 P0.05).The RI in the former group(0.798?0.165)was much higher than that in the other one(0.637?0.116)(t=4.02 P

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

Aging can cause degenerative changes in the function of multiple tissues and organs in the body. Gastrointestinal diseases and intestinal dysfunction are very common in the elderly people. The purpose of this study is to explore the effect of the total extract of Astragalus membranaceus (Fisch.) Bge. on intestinal function and gut microbiota homeostasis in natural aging mice, which will provide clues for further mechanism study. The natural aging mice model is established and animal experiments follow the regulations of the Animal Ethics Committee of Nanjing University of Traditional Chinese Medicine. The overall health of the mice was evaluated by the "frailty index" scoring method. The intestinal absorption and transport function were measured by detecting intestinal glucose absorption capacity, transport time, lipase and amylase activities of aging mice. Intestinal inflammation was assessed by detecting inflammatory cytokines by enzyme-linked immunosorbent assay (ELISA). The pathological changes in the intestines of aging mice were tested by hematoxylin-eosin (H&E) staining and alizarin blue (AB) staining. The qRT-PCR method was used to explore the gene transcription level related with the proliferation and differentiation of intestinal stem cells. Microbiota analysis based on 16S rDNA were used to evaluate the composition of gut microbiota. The results showed that Astragalus had a tendency to reduce the "frailty index" of aging mice, but did not show a significant difference. In some indicators of aging phenotype, Astragalus has the most significant effect on hair loss and physical fitness. In terms of intestinal function, Astragalus could increase intestinal glucose absorption capacity, shorten intestinal transportation time and promote lipase secretion in aging mice. The levels of inflammatory cytokines such as tumor necrosis factor-α (TNF-‍α) in the aging intestinal tissue were reduced after Astragalus administration. Astragalus also ameliorated the pathological degeneration of the intestinal tissue of aging mice by increasing the length of small intestinal villi, the thickness of colonic mucosa and goblet cell number. In addition, Astragalus elevated the expression of genes associated with the proliferation and differentiation in jejunum and modulated gut microbiota, especially restoring the abundance of Lachnospiraceae. Taken together, the above research results demonstrate the total extract of Astragalus as a key factor improving the intestinal function and gut microbiota homeostasis of aging mice.

OBJECTIVETo study the ECG features in children with dilated cardiomyopathy (DCM), and related factors for the occurrence of arrhythmia secondary to DCM.

METHODSData from 68 children with DCM from January 1998 to March 2011 were studied. The children were classified into three groups: severe arrhythmia (n=42), non-severe arrhythmia (n=20) and non-arrhythmia (n=6). Left ventricular end diastolic diameter (LVED), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were compared.

RESULTSAbnormal ECG results were found in all of the 68 children with DCM. Sinus tachycardia (91%) and ectopic pulsatile (86%) were common. LVED in the severe arrhythmia group (74±6 mm) was greater than that in the non-severe arrhythmia group (65±4 mm; P<0.05) and non-arrhythmia group (61±3 mm; P<0.05). LVED in the non-severe arrhythmia group was also greater than that in the non-arrhythmia group (P<0.05). LVEF and LVFS in the severe arrhythmia group were (30±11)% and (22±4)%, respectively, which were lower than those in the non-severe arrhythmia group［(37±12)% and (28±5)%, respectively］and non-arrhythmia group［(45±9)% and (34±7)%, respectively］(P<0.05). There were also significant differences in the LVEF and LVFS between the non-severe arrhythmia and non-arrhythmia groups (P<0.05).

CONCLUSIONSThe common abnormal ECG findings are sinus tachycardia and ectopic pulsatile in children with DCM. Arrhythmia is one of the main clinical manifestations of DCM. The occurrence of arrhythmia is associated with the left ventricular size and heart function.
