Objective To investigate the effects of Huaier Granule combined with TAC chemotherapy on immunologic function and prognosis in triple negative breast cancer patients after operation.Methods Ninty-two cases of Ⅰ-ⅢA stage triple negative breast cancer patients entered the study.They were randomly divided into control group and research group.Only TAC chemotherapy was affected in control group of 42 cases, while Huaier Granule combined with TAC chemotherapy was applied in research group of 50 cases.And we gave Huaier Granule to patients in the first day of chemotherapy.The changes of T cell subset, NK cell were detected in the patients respectively in the first day before therapy and after therapy.The five-year disease-free survival rate and overall survival rate were also observed in two groups.Results Compared with control group, the changes of T cell subset, NK cell had no significant differences in research group in the first day before therapy(P ＞0.05).In the first day after therapy, the level of CD4 + (38.16 ± 5.71) ％ in control group was significantly lower than that (44.67 ± 6.47) ％ in research group(P ＜ 0.05).However, the percentage of CD8 + T cells (28.68 ± 4.06) ％ in control group was markedly higher than that (22.85 ± 3.22) ％ in research group (P ＜ 0.05).The level of NK cell (15.75 ± 3.47) ％ in control group was obviously lower than that (19.46 ± 4.22) ％ in research group(P ＜ 0.05).The five-year disease-free survival rate is 28.6％ in control group, however the five-year disease-free survival rate is 42.0％ in research group, there were significant differences between two groups(P ＜ 0.05).Furthermore, the five-year overall survival rate in research group was obviously higher than that in control group(P ＜ 0.01).Conclusions Huaier Granule combined with TAC chemotherapy not only enhances immune function but also improves prognosis and quality of life in triple negative breast cancer patients after operation.It provides a positive exploration for anti-cancer research by integration of traditional and western medicine.

Objective To investigate the clinical significance of YMDD mutation during Lamivudine therapy on chronic hepatitis B.Methods Fluorometric analysis PCR, ELISA were used to estimate the YMDD mutation, HBVDNA quantative level and HBeAg for HBV of 72 cases with chronic hepatitis B before therapy (0 month), and after Lamivudine therapy for 9,12,18 months.Results The YMDD mutation was not observed in these cases before Lamivudine therapy. The mutation was found in 8 cases (11.1%), 17 cases (23.6%) and 28 cases (38.9%) at 9, 12, 18 month for therapy. The YMDD mutation rate rose with the therapy time lasting (P＜0.05). Moreover, the YmDD mutation rate in the patients with HBVDNA quantity higher than 108 copies/ml was significantly higher than that in the patients with HBVDNA quantity lower than 108 copies/ml (P＜0.005). The YMDD variation rate in patients with HBeAg positive and in patients with HBeAg negative showed no significant difference (P＞0.05). The HBeAg negative conversion rate was significantly higher in non-mutation group than that in mutation group (P＜0.05).Conclusion The serum virus quantity may be regard as an early estimate indication of the development of YMDD mutation during Lamivudine therapy.

In light of the IT development in hospitals, the authors point out the necessity of setting up the post of CIO and clarify the role of the CIO in the construction and management of the hospital information system. They argue that the CIO should not only be in charge of the technology support of the information network platform, but also exercise the function of managing hospital information. While hospitals ought to attach importance to the development and application of information systems and the role of the CIO, the CIO, on his part, ought to try to enhance his competence and become a versatile talent expert at various disciplines like medicine, management and the computer.

Objective To study the relationship between chromosomal abnormalities of diffuse large B-cell lymphoma and its survival time.Methods Chromosome preparations were made by using modified method.Karyotypes were analyzed by stain of G-banding. And all patients were treated by chemotherapy. All patients' survival time was calculated.Results Mitotic cells that could be used for analysis were found in 28 cases.5 of 28 karyotypes were normal and 8 cases were polyploid.There were 4 cases with t(14,18)(q32;q21),5 cases with t(3; 14) (q27;q32),2 cases with t(2;3) (p11 ;q27),1 case with t(3 ;22) (q27 ;q11) respectively.There were 2 cases with ectopia between 7 chromosome and other chromosomes and 1 case with ectopia between 17 chromosome and other chromosomes.The survival time of patients with normal karyotype,t(14,18) (q32;q21)or 3q+ was longer than that of other groups.The survival time of group in Ⅰ, Ⅱ stages was longer than that in Ⅲ, Ⅳ stages. Conclusion The treatment, survival time and prognosis could be expected according to chromosomal abnormalities and its relevance to stages in diffuse large B-cell lymphoma.

AIM: To explore the application value of polishing anterior capsule and equator in the phacoemulsification and intraocular lens implantation.

METHODS: Totally 112 cases of cataract patients in our hospital from May 2012 to January 2015 were selected as research objects. They were divided into unpolished and polished group according to whether the anterior capsule and equatorial part polished or not with the informed consents, 56 cases in each group. The patients were followed up for 18mo after phacoemulsification and intraocular lens implantation. The clinical efficacy of the two groups was compared.

RESULTS: The complication rates of the two groups were 7.1% and 16.1%, that of the polished group was lower and the difference was statistically significant(P<0.05). The lens position(effective lens position, ELP), refractive state, uncorrected visual acuity compared with unpolished group were statistically significant(P<0.05).

CONCLUSION: Polishing anterior capsule and equator can significantly improve the effect of phacoemulsification combined with intraocular lens implantation in the treatment of cataract.

Objective To evaluate the effect of propofol on liver injury in mice with acute liver failure (ALF).Methods Eighty adult male ICR mice,aged 1 months,weighing 20-25 g,were randomly divided into 3 groups (n =20 each) using a random number table:control group (group Ⅰ),ALF group (group Ⅱ),and ALF + propofol group (group Ⅲ).ALF model was established with intra-peritoneal D-galactosamine (D-GaIN) and lipopolysaccharide (LPS).Propofol 5 mg/kg was injected via the tail vein every 1 h within 6 h after injection of DGaIN and LPS in group Ⅲ,while the equal volume of normal saline was given instead in the other groups.Venous blood samples were taken from the tail vein at 1,3 and 6 h after injection of D-GaIN and LPS (T1-3) to detect the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and serum tumor necrosis factor-alpha (TNF-α),interleukin-1β (IL-1β) and IL-10 concentrations (by ILISA).The survival within 12 h after injection of D-GaIN and LPS was observed and the survival rates were calculated.The mice were sacrificed and livers were removed for microscopic examination of pathologic changes.Results Compared with group Ⅰ,the activities of AST and ALT were significantly increased at each time point in Ⅱ and Ⅲ groups and the serum TNF-α concentrations at T1,2 and IL-1β and IL-10 concentrations at each time point were significantly increased in group Ⅱ,and the serum TNF-α concentrations at T1,and IL-1β and IL-10 concentrations at T2,3 were significantly increased in group Ⅲ (P ＜ 0.05).Compared with group Ⅱ,the activities of AST and ALT at each time point,serum TNF-α concentrations at T1,2 and IL-1β and IL-10 concentrations at T2,3 were significantly decreased and the survival rate within 12 h after injection of D-GaIN and LPS was increased in group Ⅲll (P ＜ 0.05).The pathologic changes of liver tissues were gradually attenuated in Ⅱ and Ⅲ groups.Conclusion Propofol can reduce the liver injury in mice with ALF through inhibiting inflammatory responses.

AIM: To study the effect of Lomerizine on the activity of P-glycorprotein (P-gp) in primary cultured rat brain microvessel endothelial cells (RBMECs). METHODS: Flow cytometry was used to study the efflux of rhodamine123 (Rh123) and expression of P-gp in RBMECs. RT-PCR was used to measure the expression in mRNA level of mdr1 gene in RBMECs. Transwell model was used to detect the influence of Lomerizine on the transport of Rh123 through RBMECs monolayer. RESULTS: Lomerizine inhibited the efflux of Rh123 in RBMECs. No changes of P-gp and mdr1 gene mRNA expression were detected in RBMECs after the treatment with 30 μmol·L-1 Lomerizine for 72 h. In the study of Transwell model, Lomerizine increased significantly the transport of Rh123 through RBMECs monolayer from upper compartments to lower compartments, and inhibited obviously the transport in reverse direction. CONCLUTION: The effect of Lomerizine on the activity of P-gp was mainly via its direct inhibitory effect on the function of P-gp in RBMECs and the transport of P-gp substrates in BBB may be affected by lomerizine.

Objective To investigate the effects of ischemic postconditioning on mitochondrial permeability transition and mitochondrial transmembrane potential(△Ψm)following hepatic ischemia-reperfusion(I/R)in rats.Methods Forty male SD rats weighing 220-260 g were randomly divided into 5 groups with 8 animals in each group:sham operation group(group S);atractyloside+sham operation group(group A+S);I/R group;ischemic postconditioning group(group IPO)and atractyloside+ischemic postconditioning group(group A+IPO).The animals were anesthetized with intramuscular injection of atropine 0.05 mg/kg.Hepatic I/R was produced by occlusion of hepatic blood flow for 60 min followed by 6 h reperfusion.In group A+S,atractyloside 5 mg/kg was injected intravenously before abdomen Was closed.In group IPO,the animals were subjected to 3 cycles of 1 min reperfusion interspersed with 1 min hepatic isehemia at the end of 60 min hepatic ischemia.In group A+IPO,atractyloside 5 mg/kg was injected intravenously before reperfusion. Venous blood samples were collected for determination of serum ALT and AST activities immediately before ischemia and at 6 h of reperfusion. The animals were then sacrificed.Their livers were removed for microscopic examination, detection of apoptosis and determination of cytochrome c (Cyt c) expression, △Ψm and mitochonerial permeability transition pore (MPTP)activity. Apoptosis index (AI) was calculated. Results There was no significant difference in serum ALT and AST activities, AI, Cyt c expression, △Ψm and MPTP activity between S and A + S groups (P＞0.05). Compared with group S, serum ALT and AST activities and AI were significantly increased, Cyt c expression was up-regulated, △Ψm was decreased and MPTP activity was increased in groups I/R, IPO and A+IPO(P＜0.05).Compared with group I/R, serum ALT and AST activities and AI were significantly decreased,Cyt c expression was down-regulated, △Ψm was increased and MPTP activity was decreased in group IPO(P＜0.05), while no significant change was found in group A+IPO(P＞0.05).Compared with group IPO,serum ALT and AST activities and AI were significantly increased, Cyt c expression was up-regulated, △Ψm was decreased and MPTP activity was increased in group A + IPO(P＜ 0.05).Microscopic examination showed that hepatic injury was reduced in group IPO compared with group I/R, while aggravated in group A+ IPO compared with group IPO. Conclusion Ischemic postconditioning can protect liver from I/R injury by attenuating the I/R-induced increase in MPTP opening and decrease in △Ψm in rats.

Objective To investigate the protective effect of propotol against hepatic ischemiareperfusion injury in rats on mitochondrial permeability transition pore (MPTP) and the mechanism of GSK-3β.Methods Thirty SD rats were randomly assigned into five groups (n =6):sham operation group (S group),ischemia reperfusion group (I/R group),CsA pretreatment group (C group),propofol pretreatment group (P group),and propofol plus atractyloside pretreatment group (A + P group).Nauta liver ischemia-reperfusion rat model was used.Liver lobes were subjected to warm ischemia for 60min and then reperfusion for 120 min.In P group,propofol [12 mg/(kg · h)] was administered in the femoral vein for 30 min before ischemia until the end of reperfusion.In C group,CsA (2 mg/kg) was administered in the femoral vein for 20min before ischemia.In A + P group,20 μmol/kg of atractyloside was given through the femoral vein 10min before the injection of propofol.Rats were sacrificed at the end of reperfusion,and venous blood and hepatic tissue specimens from the same part of ischemia were obtained from different groups.Results Compared with S group,the AST and ALT levels were increased significantly,mitochondrial swelling were increased and mitochondrial membrane potential were decreased significantly in I/R group and A + P group.Casepase-3 were increased significantly and p-GSK3β Ser9 were decreased significantly in I/R group and A + P group.Compared with I/R group,the content of AST and ALT were decreased significantly,mitochondrial swelling were decreased and mitochondrial membrane potential were increased significantly,casepase-3 release were decreased significantly and p-GSK3β Ser9 were increased significantly in P group and C group.GSK-3β in each group displayed no significant difference.Conclusions Propofol can significantly reduce hepatic ischemia-reperfusion injury.The protective effect of propofol may be achieved via the inhibition of GSK-3β activation,increased p-GSK-3β Ser9 level,suppressing MPTP opening and decreasing hepatocytes apoptosis.

Objective To assess the effects of 7,8-dihydroxyflavone (7,8-DHF) on the striatum (ST) in normal cynomolgus monkeys using 99Tcm-TRODAT-1 imaging.Methods A total of six healthy female cynomolgus monkeys were included in this study.Three of them were fed with normal food (control group),and the other three were given oral administration of 7,8-DHF in addition to normal food (experimental group).The SPECT/CT imaging was performed at different time after 99Tcm-TRODAT-1 injection.The ROI of ST was drawn on images of 3 consecutive transverse slices that could be visualized best.The cerebellum (CB) was taken as the background reference area.The radioactivity uptake ratios of ST/CB at 1,3,4 and 5 h were calculated respectively.Paired-t test was used to analyze the data.Results ST radioactive uptake ratios showed continuing increase on the delay images.ST/CB uptake ratios of the control group at 1,3,4 and 5 h were 1.43±0.04,1.82±0.06,2.04±0.12,2.42±0.23,respectively,and those of the experimental group were 1.35±0.08,2.40±0.09,2.74±0.13 and 3.25±0.15 respectively.There was no significant difference between the two groups at 1 h (t =2.57,P＞0.05),while ST/CB uptake ratios of the experimental group at 3,4 and 5 h were significantly higher (t values:2.77,2.87 and 2.92,all P＜0.05).Conclusion 99Tcm-TRODAT-1 SPECT/CT imaging can be used to assess the DAT activation effect by 7,8-DHF on ST of cynomolgus monkeys.
