Objective To explore the value of anatomical liver resection in the treatment of bilateral intrahepatic biliary lithiasis. Methods We collected the clinical data of 32 patients with bilateral intrahepatic biliary lithiasis who received anatomical liver resection and 25 patients who recevied non-anatomical liver resection from May 2010 to May 2012 in our hospital and Sun Yat-sen Memorial Hospital. We comapred the therapeutic efficacy of these two operative modalities in the diagnosis and treatment of bilateral intrahepatic biliary lithiasis. Results The intraoperative blood loss was 436 ±48.162 mL in patients who received anatomical liver resection, and was significantly less than that in the control group (763 ± 37.645ml) ( < 0.05 ) . Postoperative liver function status:for patients who received anatomical liver resection,on the third day after operation,the total bilirubin and AST were significantly lower than those in the control group ( <0.05), and the postoperative hospitalization time was also shorter than that of the control group ( <0.05 ) . The two groups in the operation time, postoperative complications and residual calculus had no significant difference ( >0.05 ), but there 1 patients died of liver failure in the control group. Conclusions Anatomical liver resection is a favorable method to completely remove the lesions under the premise of retaining the residual liver function as much as possible. The rate of remnant biliary lithiasis and recurrence is lower and the recovery is quicker in these patients after anatomical liver resection. Thus, anatomical liver resection is worthy of promotion.

Objective To observe the effects of Liuwei Buqi capsules on CD4+CD25+forkhead box protein 3+(Foxp3+)regulatory T cells(Tregs),helper T cells(Ths)in patients with chronic obstructive pulmonary disease (COPD). Methods Eighty COPD patients admitted into the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from January 2012 to May 2013 were randomly divided into a traditional Chinese medicine (TCM)experimental group(40 cases)and a western medicine control group(40 cases);there were 40 research volunteers enrolled as healthy controls. After admission,both the TCM experimental group and western medicine control group were given conventional western medicine comprehensive treatment. Additionally,in the TCM experimental group,Liuwei Buqi capsules were given orally once 3 pills(0.4 g/pill)and twice a day,while in the western medicine control group nifedipine was given,once 10 mg and 3 times a day,30 days constituting one therapeutic course for both groups. BODE evaluation means that the body mass index(B),the degree of airflow obstruction(O),the scores of dyspnea(D)and excercise capacity(E)of COPD patients were evaluated. A spirometer was used to observe the changes in the patient's pulmonary function to detect the dyspnea score. The γ-interferon(IFN-γ),interleukin (IL-4 and IL-17)in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of Treg of peripheral blood was detected by flow cytometry. Results Compared with healthy control group,lung function parameters,IL-4,CD4+CD25+Treg and CD4+CD25+Foxp3+Treg of peripheral blood were increased,while dyspnea score,BODE score,the expressions of IFN-γ,Th1/Th2,IL-17 in serum were decreased significantly in the COPD group(P<0.05 or P<0.01). After treatment,compared with those before treatment in the two groups, the forced expiratory volume in 1 second(FEV1),FEV1/forced vital capacity(FVC),IL-4,CD4+CD25+Treg, CD4+CD25+Foxp3+ Treg were all increased,while dyspnea score,BODE score,IFN-γ,Th1/Th2,IL-17 were all decreased(P<0.05 or P<0.01),and the peak expiratory flow(PEF)was decreased in western medicine control group and increased in TCM experimental group. After treatment,the comparisons of ratio of FEV1/FVC〔(78.12±14.96)%vs.(67.52±10.39)%〕,BODE score(1.07±0.72 vs. 1.77±0.74),IL-17(μg/L:40.80±8.97 vs. 48.22±6.51) Th1/Th2(1.05±0.23 vs. 1.42±0.21)and CD4+CD25+Foxp3+ Treg〔(6.61±2.26)% vs.(5.25±2.03)%〕between the two groups were all of statistical significant difference(all P<0.05). Conclusion Liuwei Buqi capsules can improve COPD symptoms by up-regulating the expressions of CD4+CD25+Foxp3+ Treg,IL-4,and down-regulating the expressions of IFN-γ,IL-17 to correct the balance of Th1/Th2 in patients with COPD.

Objective To explore the influence of TAC protocol (pirarubicin,cyclophosphamide and docetaxel) and AC-T protocol (pirarubicin,cyclophosphamide and sequential docetaxel) on T lymphocytes cell subsets (included CD3+ T cells,CD3+ CD4+ T cells,CD3+ CD8+ T cells,CD3+ CD4+/CD3 + CD8+),natural killer (NK) cells and part of the quality of life in the peripheral blood of patients.Methods A total of 66 patients with breast cancer included 31 cases for TAC protocol (6 cycles of chemotherapy) and 35 cases for AC-T protocol(8 cycles of chemotherapy).Collected respectively before and after the last chemotherapy of peripheral blood,used flow cytometry technique to detect the proportion of T cell subsets and NK cells in peripheral blood,and compared the change of the part of the quality of life before and after chemotherapy.Results After chemotherapy of total of 66 patients CD3+ T cells,CD3+ CD4+T cells and NK cells of peripheral blood ((68.58± 11.03) ％,(33.53 ± 8.84) ％,(18.27 ± 10.65) ％) significantly lower than before chemotherapy ((74.03±13.04)％,(38.42±9.79)％,(19.83± 10.19)％),the differences were statistically significant(t =4.296,3.387,4.092,P＜ 0.05).Grouping was TAC protocol with AC-T,T cell subsets and NK cells before chemotherapy differences had no statistical significance.But after chemotherapy,CD3+ T cells,CD3+ CD4+T cells,CD3+CD8+ T cells and Karnofky score((64.63±10.01)％,(31.19±7.41)％,(24.66±7.40)％,(68.63± 5.100)％) of peripheral blood on TAC protocol were more decreased than AC-T protocol((72.29± 10.78)％,(35.74± 9.60) ％,(30.15 ± 11.12) ％,(77.29 ± 4.58) ％),the differences were statistically significant (t =2.99,2.15,2.35,2.237,P＜0.05).CD3+ CD4+/CD3+ CD8+ and NK cells were also decreased,but without statistical significance.The body quality of 66 patients was slightly increased after chemotherapy,but without statistical significance.Conclusion The body's immune function and the part of quality of the breast cancer patient's life have declined by chemotherapy drugs in varying degrees.Compared TAC,AC-T protocol has less influence on the immunological function and the part of living quality of patients with breast cancer.

Methods Twenty Sprague-Dawley(SD)rats were randomly divided into normal control group and COPD model group,with 10 rats in each group. The COPD model was reproduced by smoke inhalation and tracheal instillation of lipopolysaccharide(LPS),and no such treatment was conducted in normal control group. Twenty-eight days after the model reproduction,the pulmonary function was determined,the pathological changes of lung tissue were observed with haematoxylin-eosin(HE)staining,interleukins(IL-6,IL-10)in serum were detected by enzyme-linked immunosorbent assay(ELISA),CD4+CD25+Foxp3+Treg of peripheral blood was determined by flow cytometry,and the expressions of Foxp3,RORγt,IL-17 protein in lung tissue were assayed by Western Blot. Results Under light microscope,significal interstitial infiltration of inflammatory cells was found in alveoli and interstitial tissue of the lung,and destruction of alveolar tissue,alveolar wall thinning,and even rupture to fuse into bullae,and bleeding into alveoli in different degress could be observed. Compared with the normal control group,forced vital capacity(FVC),forced expiratory volume in 0.3 second(FEV0.3),FEV0.3/FVC,peak expiratory flow(PEF)in model group were significantly decreased〔FVC(mL):8.04±2.03 vs. 9.97±2.14,FEV0.3(mL):6.16±2.23 vs. 8.84±2.12,FEV0.3/FVC:0.70±0.09 vs. 0.85±0.11,PEF(mL/s):33.56±4.76 vs. 40.14±5.64, P<0.05 or P<0.01〕. Serum IL-6 was obviously increased(ng/L:93.17±20.96 vs. 76.28±13.24,P<0.05), IL-10 was significantly decreased(ng/L:78.62±15.17 vs. 104.34±19.46,P<0.01),and CD4+CD25+FoxP3+Treg was significantly diminished〔(2.75±0.83)% vs.(4.16±1.14)%,P<0.01〕in model group compared with those in the normal control group. The expression of Foxp3 protein in lung tissue in model group was significantly down-regulated compared with that in the normal control group(gray scale:0.38±0.15 vs. 0.63±0.11,P<0.01), and RORγt and IL-17 protein expressions were significantly up-regulated〔RORγt(gray scale):0.96±0.23 vs. 0.47±0.11,IL-17(gray scale):1.02±0.24 vs. 0.34±0.08,both P<0.01〕. Correlation analysis showed that FEV0.3 was positively correlated with Foxp3(r=0.585,P<0.05),and FEV0.3/FVC was negatively correlated with IL-6 and RORγt(r=-0.655,r=-0.607,both P<0.05). PEF was positively correlated with Treg(r=0.573, P<0.05),and negatively correlated with IL-17(r=-0.198,P<0.05). IL-6 was negatively correlated with Foxp3(r=-0.603,P<0.05),and positively correlated with RORγt(r=0.588,P<0.05). IL-10 was positively correlated with Treg(r=0.573,P<0.05). Treg was positively correlated with Foxp3(r=0.607,P<0.05), and negatively correlated with IL-17(r=-0.569,P<0.05). Foxp3 was negatively correlated with RORγt(r=-0.591, P<0.05). RORγt was positively correlated with IL-17(r=0.578,P<0.05). Conclusion There is a relationship among decreased pulmonary function,inflammation and imbalance of Foxp3/Treg and RORγt/Th17 in COPD.

BACKGROUND: Studies have demonstrated that exogenous neural stem calls (NSCs) could repair nerve and promote recovery of neurofunction following cerebral hemorrhage. However, the influence of internal environment after cerebral hemorrhage on the survival and differentiation of NSCs is a complex and variable process.OBJECTIVE: To observe the survival and differentiation of human embryonic NSCs implanted in rats with cerebra hemorrhage.DESIGN, TIME AND SETTING: Open, immunohistochemistry, experiment was performed at the Laboratory of Molecular Biology, Affiliated Hospital of Luzhou Medical College from May 2007 to April 2008.MATERIALS: A total of 40 female SD rats were provided by the Experimental Animal Institute, Chinese Academy of Medical Sciences. Brain of 8-week aborted fetus was obtained from Department of Gynaecology and Obstetrics, the People's Hospital of Deyang City.METHODS: Cerebral cortex cells of 8-week aborted human fetus were harvested and cultured in vitro to obtain human embryonic NSCs. Cerebral hemorrhage rat models were established via injection of autologous arterial blood in caudate nucleus. Two days after modeling, 5 μL BrdU-labeled human embryonic NSCs suspension was transplanted at four points surrounding hematoma cavity in the rats. After 1 and 2 weeks, rats were sacrificed. Adjacent sections were doubly stained by BrdUImicrotubule-associated protein 2 (MAP-2) and BrdU/glial fibrillary acidic protein (GFAP).MAIN OUTCOME MEASURES: The survival, immigration and differentiation of human embryonic NSOs implanted in rats were observed by immunohistochemistry and immunofluorescance staining.RESULTS: BrdU-positive cells were oval and brown. At 1 and 2 weeks after implantation, BrdU-positive calls survived and migrated, and they migrated more widely at 2 weeks after implantation. At 1 week after implantation, BrdU/MAP-2-positive cells and BrdU/GFAP-positive calls were observed in cerebral tissue sections, and the number of BrdU/MAP-2-positive cells was more than BrdU/GFAP-positive calls; At 2 weeks after implantation, BrdU-positive cells found in choroid plexus and blood capillary were significantly reduced, and BrdU/GFAP-positive calls were more than BrdU/MAP-2- positive cells.CONCLUSION: Implanted human embryonic NSCs can survive and migrate in the hemorrhage region, gradually differentiate into neurons or astrocytes.
