Objective To study the immediate conservative breast surgical reconstruction by trans-ferring the same lateral latissimus dorsal myocutaneous flap (LDM) for the treatment of stage Ⅱ and stage Ⅲ breast cancer, combined with neoadjuvant chemotherapy. Methods Breast cancer patients in stage Ⅱ and Ⅲ with pathological diagnosis by core needle biopsy, had undergone immediate conservative breast reconstruction surgery with transferring the latissimus dorsal myocutaneous (LDM). We scored the reconstructed breast twice at one month after operation and completion of radiation. The final score was decided using the mean value of the twice evaluating score. Kaplan-Meier survival was used to analyze the survival of 18 cases with traditional mastectomy. Results The tumor size ranged from 30 mm to 55 mm before neoadjuvant chemotherapy, and ranged from 25mm to 45 mm after neoadjuvant chemotherapy. The median weight of the tumor specimens in breast conservative operation was 140 g (90 g to 220 g). A-mong the 18 patients, 16 cases had more than 3 scores with satisfied cosmetics (93.33 % ). Dorsal subcu-taneous seroma in donation area was observed in 5 of 18 patients (27.78 %) and dorsal incision dehiscence was observed in 2 of 18 patients (11.11%). None of the patients developed recurrence except that 1 pa-tient (5.55 %) had distance metastasis (bone metastasis} in a mean 22-months follow-up. The Kaplan-Meier survival curve in breast conservation reconstruction patients had no different from that of traditional mastectomy patients at the same time. Conclusions Immediate conservative breast surgical reconstruction by using the same lateral latissimus dorsal myocutaneous flap is an effective method for stage Ⅱ and stage Ⅲ breast cancer patients combined with neoadjuvant chemotherapy, which can increase satisfactory breast so that cosmetic outcome can be reached.

Objective To explore the roles of macrophage inflammatory protein-1?(MIP-1?)in hypoxic-ischemic encephalopathy(HIE)of newborn infarnts.Methods Serum samples were obtained in 24,72 h and 7 d after birth respectively from 34 newborn infants with HIE,and 20 newborn infants without HIE as control group.Enzyme-linked immunosorbent assay(ELISA)method was used to determine the serum concentrations of MIP-1?.Results Levels of MIP-1? in newborn infants with HIE [(12.47?2.51)ng/L]were significantly higher than that of newborn infants without HIE [(8.63?2.63)ng/L](P0.05).Conclusions MIP-1? are involved in HIE of neonates,and the more severe damage,the higher levels in serum,which suggests that,as an inflammatory mediator,the MIP-1? may play an important role in involvement of brain hypoxic-ischemic damage.

Current study was carried out to optimize the priming condition of Oldenlandia diffusa seeds, and improve germination rate and seed vigor of 0. diffusa seeds under drought conditions. Uniform design was used to optimize the concentration and priming time of three priming materials (PEG, KNO3, GA3). Different concentrations of polyethylene glycol (PEG) was used to simulate drought stress. The seedling was cultured in 1/4 Hoagland medium for 30 d. The results showed that seed priming treatment with 366 mg x kg(-1) GA3 for 1h resulted in significant increase in germination rate, germination index, vigor, root length, plant height and biomass of O. diffusa seeds under drought stress (15% PEG), while seed priming with 3.0% KNO3 for 1 h showed little effect on germination and growth of O. diffusa seeds under drought stress. Seed priming treatment with appropriate GA3 concentration and priming time could enhance seed germination and drought resistance of O. diffusa in seedling stage.

Abstract:Objective To elucidate the mechanisms by which Epstein-Barr virus-encoded latent membrane protein 1 activates NF-κB in nasopharyngeal carcinoma cells.Methods A tetracycline-regulated LMP1-expressing nasopharyngeal carcinoma cell line, Tet-on-LMP1-HNE2, was used as the cell model. The kinetics of the expression of proteins, including LMP1, IκBα and IκBβ, was analyzed by Western blotting. The subcellular localization of NF-κB (p65) was detected by indirect immunofluorescence assay. The NF-κB transactivity was studied by transient transfection and reporter gene assay. Results IκBα was phosphorylated and degraded after the inducible expression of LMP1, although the total protein levels remained stable. The steady-state level of total IκBβ protein may have resulted from the initiation of an autoregulation loop after the activation of NF-κB. No change in the IκBβ level was detected. NF-κB (p65) was translocated from the cytoplasm to the nucleus following degradation of IκBα. After the introduction of the dominant-negative mutant of IκBα (Del 71) into Tet-on-LMP1-HNE2 cells, both nuclear translocation and transactivation of NF-κB induced by LMP1 was significantly inhibited. Conclusions The results indicated that in nasopharyngeal carcinoma cells, LMP1 activated NF-κB via phosphorylation and degradation of IκBα, but not IκBβ. The dominant-negative mutant of IκBα (Del 71) could completely inhibit both the nuclear translocation and transactivation of NF-κB induced by LMP1.

Objective To investigate the changes of Th1/Th2 cells and related cytokine levels in chronic hepatitis B (CHB) fibrosis.Methods Forty-six patients with CHB fibrosis underwent liver biopsy during March and October,2011.According to the stage of fibrosis,the patients were divided into S0-1 group (n =15),S2-3 group (n =20) and S4 group (n =11).Ten healthy subjects served as controls.The frequencies of circulating Th1,Th2 cells were detected by flow cytometry.The expressions of interferon-γ (IFN-γ) and interleukin 4 (IL-4) mRNA in peripheral blood mononuclear cells (PBMCs) were detected by real-time quantitative PCR.The serum IFN-γand IL-4 concentrations were determined by enzyme-linked immunosorbent assays.Intrahepatic expressions of IFN-γ and IL-4 were detected by immunohistochemical staining.Differences between groups were analyzed using non-parametric Kruskal-Wallis H test,followed by Mann-Whitney U test for multiple comparisons.Logistic regression was used for multivariate analysis.Results With the degree of liver fibrosis exacerbations,the peripheral Th1/Th2 cells frequencies ratio,IFN-γ/IL-4 mRNA ratio in PBMCs,serum IFN-γ/IL-4 ratio and intrahepatic IFN-γ/IL-4 ratio were declined (x2 =36.259,40.822,26.321 and 31.852,respectively,all P ＜ 0.05).Serum and intrahepatic IFNγ/IL-4 ratio were negatively associated with the stage of liver fibrosis (r =-0.616 and-0.531,P ＜0.01).Logistic regression analysis showed that AST,PT and the serum IFNγ/IL-4 ratio were the risk factors for significant liver fibrosis (S2-4) (OR =5.933,95％ CI:1.324-26.586,P =0.02; OR =12.866,95％CI:1.746-94.788,P =0.01; OR=4.755,95％CI:1.034-21.862,P =0.04).Conclusions The CHB patients has imbalanced Th1/Th2 ratio.With the degree of liver fibrosis exacerbations,Th1/Th2 cytokines drift into Th2 lymphocyte sub-cluster,which suggests that Th1/Th2 imbalance may be involved in the pathogenesis of CHB fibrosis.

OBJECTIVETo study the clinical characteristics of hepatitis-associated aplastic anemia (HAAA). A retrospective analysis was conducted among 8 cases of established HAAA in light of the clinical and laboratory findings and the patient outcomes.

METHODSSerum samples from 8 patients with HAAA were tested for the antibodies to hepatitis viruses A, B, C, D, E and CMV, and 7 patients showed negative serological results while only one was positive for HBsAg. The percentage of CD4(+) cells was significantly lowered while the percentage of CD8(+) cells significantly increased to result in a lowered ratio of CD4(+)/CD8(+) cells in these HAAA patients. A shift in the Th1/Th2 and Tc1/Tc2 balance to a Th1 and Tc1 dominance was noted. The percentage of Treg cells was obviously decreased. Significant increments were found in the serum levels of interleukin-2, THF-α and interferon-γ. Three of the patients responded to immunosuppresssive treatment; one patient achieved a complete remission, two had a partial remission, and five failed to respond to the therapy and died.

CONCLUSIONSHAAA may not have an obvious association with viral infections as by hepatitis virus A, B, C, D, or E, and its pathogenesis often involves abnormalities of the T cell immunity. Commonly with a poor prognosis, HAAA is associated with a high mortality rate.

OBJECTIVETo explore the different effects of rectal application of Neiyi Kangfu Suppository (NYKFS) on the expressions of cytochrome C (Cyt C) and Survivin in ectopic and eutopic endometrium in endometriosis (EMT) model rats.

METHODSEMT rats were randomly divided into 6 groups, the high- and low-dose NYKFS groups, the Danazol Capsule (DN) group, the Dan'e Fukang Soft Extract (DFE) group, the model group and the blank group. The expressions of Cyt C and Survivin were measured using immunohistochemical SP staining method.

RESULTS(1) After treatment, the IOD value of Cyt C in ectopic endometrium significantly increased in the high-dose and low-dose NYKFS groups respectively to 6.08 +/- 0.35 and 6.23 +/- 0.35, which was significantly higher than that in the model group (5.07 +/- 0.70) and DFE group (5.98 +/- 1.02) respectively (P < 0.05, P < 0.01); while those of Survivin in ectopic endometrium was significantly decreased to 5.73 +/- 0.93 and 5.62 +/- 0.93 and was significantly lower than that in the model group (6.01 +/- 1.16, P < 0.05 or P < 0.01). (2) The lowered eutopic endometrial level of Cyt C in EMT rats after treatment was significantly higher in the two NYKFS groups than that in the model group (P < 0.05); while that of eutopic endometrial Survivin was insignificantly different between the NYKFS groups and the model group or the blank group (P > 0.05).

CONCLUSIONNYKFS plays its role in inducing apoptosis by increasing the expression of Cyt C and decreasing the expression of Survivin in ectopic endometrium, but it up-regulates expression of Cyt C, has no obvious effect on Survivin expression in eutopic endometrium.

OBJECTIVETo observe the effect of bear bile powder (BBP) on the STAT3 pathway and its downstream target genes of nude mice hepatocellular carcinoma (HCC) xenograft, and to explore its mechanism for treating HCC.

METHODSThe subcutaneous xenograft model was established using HepG2 cells. When the subcutaneous transplanted tumor was formed, naked mice were randomly divided into two groups, the BBP group and the control group. Mice in the BBP group were administered with BBP by gastrogavage, once daily for 3 consecutive weeks, while mice in the control group were administered with normal saline by gastrogavage, once daily for 3 consecutive weeks. The body weight and the tumor volume were measured once per week. By the end of medication, the tumor weight was weighed and the tumor inhibition ratio calculated. The apoptosis of the tumor tissue was detected by TdT-mediated dUTP nick end labeling (TUNEL). The expression of Bcl2-associated X protein (Bax), B cell lymphoma/eukemina-2 (Bcl-2), cyclin-dependent protein kinase (CDK4), cyclinD1 were detected by reverse transcription-polymerase chain reaction (RT-PCR). The protein expression levels of signal transducers and transcription activators 3 (p-STAT3), proliferating cell nuclear antigen (PCNA), Bax, Bcl-2, CDK4, and cyclinD1 were determined by immunohistochemistry.

RESULTSBBP could inhibit the tumor volume and tumor weight, showing statistical difference when compared with the control group (P < 0.01). Results of TUNEL showed that BBP could significantly induce the apoptosis of hepatoma carcinoma cells. Results of RT-PCR showed that BBP could up-regulate the expression of Bax and down-regulate mRNA expression of Bcl-2, CDK4, and cyclinD1. Immunohistochemical results showed that BBP could up-regulate the expression of Bax and inhibit the protein expression of p-STAT3, PCNA, Bcl-2, CDK4, and cyclinD1.

CONCLUSIONBBP could induce the apoptosis of hepatoma carcinoma cells and inhibit their proliferation by regulating STAT3 pathway.
