Background and purpose:The morbidity of the elderly patients with hepatic portal cholangiocarcinoma is rising. Due to the characteristics of pathology,physiology and anatomy of the disease, most of the patients with cancer are not resectable, the main treatment consists of the diverting drainage and postoperative chemoradiation.We studied the clinical features and the effective therapeutic method for the elderly patients with hepatic portal cholangiocarcinoma. Methods:A retrospective analysis was performed in 28 cases of the elderly patients with hepatic portal cholangiocarcinoma who were treated between January 1995 and December 2005 in our hospital.Results:3 cases received surgery, 2 of them survived for over three years, another 3 cases were given operative exploration with 14 months of medium survival time. 22 cases were given internal or external drainage and received radiotherapy after operation, their survival time ranged from 5 months to 40 months.Conclusions:Surgery is the primary therapeutic method for elderly patients with hepatic portal cholangiocarcinoma. Internal or external drainage and radiotherapy could prolong survival time of the patients with unresectabke disease.

Objective To investigate the characteristic changes of the metabolism products in auditory cortex (transverse temporal gyrus) in patients with OSAHS combined with nerve deafness using 1 H magnetic resonance spectroscopy (1 H - MRS) ,and to discovery the early warning indicator of nerve deafness in OSAHS .Methods PTA was performed in 95 patients with OSAHS (diagnosed by PSG) ,and 15 healthy control subjects ,the patients were classified into four groups :the group of OSAHS ;OSAHS with unilateral and bilateral deafness ,the normal control group .Cerebral metabolism was studied by assessing the ratios of nitro -acetyl aspartate contrast to choline (NAA/Cho) as well as to creatine (NAA/Cr) ,myo -inositol to creatine (mI/Cr) and choline to creatine (Cho/Cr) ratios in the auditory cortical separately in these groups .ROC curves were made for those metabolism markers to find the best diagnositic threshold .Results Significantly lower values of NAA/Cho ratio were found in patients'(OSAHS with deafness) auditory cortex compared with 15 age-matched control subjects (P<0 .05) and OSAHS without deafness (P<0 .05) .Auditory cortical NAA and NAA/Cho ratio in OSAHS with unilateral nerve sensorineual hearing were significantly lower than those of in normal control (P<0 .05) ,but there was no significant difference be-tween the abnormal and ontralateral normal auditory cortex by a self comparison .All of the metabolisms were tested by the curve of ROC .Conclusion Combined with the changes of metabolism ,and the curve of ROC ,NAA/Cho may be the early warning markers of sensorineual hearing was in OSAHS patients .

Purpose To evaluate the value ofintravoxel incoherent motion (IVIM) imaging in diagnosis of liver fibrosis staging in rats.Materials and Methods Rabbit models of liver fibrosis at different stages were established.All rabbits were divided into four groups based on the pathological results of fibrosis grading as S1-S4.The 1VIM imagings with 8 b-values (0,50,100,200,300,800,1000,1200 s/mm2) were performed.The diffusion coefficient (D),perfusion-related coefficient (D*),and perfusion fraction (f) were calculated and compared between control (only injection of saline) and S 1 group,S2 and S3 group.Results The D value was significantly lower in S1 group compared with control group (P＜0.05),but the D* and f values showed no significant difference between the two groups (both P＞0.05).With the progression of liver fibrosis,the D,D* and f value decreased gradually;the D* value showed significant difference between S2 and S3 group (P＜0.05),but the D and f values showed no significant differences between the two groups (both P＞0.05).Conclusion The D value is useful for differentiation of normal liver and hepatic fibrosis of S1 stage,while the D* is valuable for differentiation of hepatic fibrosis of S2 and S3 stage.However,the f value neither could detect early fibrosis,nor could differentiate hepatic fibrosis staging.IVIM imaging provides a noninvasive method for early and accurate staging of liver fibrosis,which may be of great help in clinical diagnosis and treatment.

Objective To investigate the inhibitory effect of rhIFN-γ on human chronic myeloid leukemia cell line K562,and the impaction on the expression of CD123.Methods MTT method was used to test cell relative viability with rhIFN-γ at different concentrations.The expression of CD123 on K562 ceils was detected by flow cytometry.Results The relative inhibition of K562 cells proliferation was hampered when the cells were treated with rhIFN-γ for 72 h at the concentration of 5 x 10P ～ 108 U/L,respectively.However,rhIFN-γ at 2 x 105 U/L was benefit to K562 cells proliferation.After treatment with rhIFN-γ at 0,2 x 105 U/L and 107 U/L,the percentages of CD123 expression on K562 cells were (4.10 ± 1.46) ％,(7.2 ± 2.50) ％ as well as (21.6 ± 1.17) ％,respectively.Compared with the control group,107 U/L rhIFN-γ significantly increased the expression of CD123 on K562 cells (P＜0.05).Conclusion The effect of rhIFN-γ on the growth of K562 cells has two aspects (inhibition or proliferation),and it can increase the expression of CD 123.

OBJECTIVETo explore the feasibility and safety of abdominosacral resection for patients with locally advanced primary low rectal cancer.

METHODSA total of 97 low rectal cancer patients were amenable to surgery but not anal sphincter preservation were included in this study and divided into the abdominoperineal resection group(n=49) and abdominosacral resection group(n=48) according to the order of alternative admission time between June 2010 and January 2012. Intraoperative and postoperative parameters were compared between the two groups.

RESULTSThe surgery went well and no perioperative mortality in the two groups. Compared with abdominoperineal resection group, the operative time of abdominosacral resection group(including the 2nd position adjustment time) was longer[(188±45) min vs. (143±48) min, P=0.000], the unexpected prostate or vagina injury incidence was lower [0 vs. 14.3%(7/49), P=0.032), and the perineal wound infection rate was lower [2.1% (1/48) vs. 18.4% (9/49), P=0.040].

CONCLUSIONAbdominosacral excision is feasible and safe for patients with locally advanced primary low rectal cancer.

OBJECTIVETo investigate the changes of gene expression file in transitional cell carcinoma of bladder after hepatocyte cell adhesion molecule(hepaCAM) overexpression.

METHODSAffymetrix Human Genome U133 Plus 2.0 Array was used to investigate the changes of gene expression profile between adenovirus-green fluorescent protein(GFP) -hepaCAM group and GFP group in transitional cell carcinoma of bladder EJ cells.Significant Analysis of Microarray(SAM) was used to screen the differentially expressed genes, DAVID software was used to conduct gene ontology analysis and wikiPathway analysis based on the differentially expressed genes. Reverse transcription-polymerase chain reaction and Western blot were applied to verify microarray data.

RESULTSCompared with the GFP group, a total of 2469 genes were up-regulated or down-regulated by more than 2 times in the GFP-hepaCAM group. Among these genes, 1602 genes were up-regulated and 867 were down-regulated.Most of the differentially expressed genes were involved in the function of cell proliferation and cell cycle regulation. The mRNA expressions of nibrin, liver kinase B1, and cyclin D1 detected by reverse transcription-polymerase chain reaction in three different bladder cancer cell lines were consistent with the microarray data.The protein expressions of nibrin and liver kinase B1 in these three cell lines measured by Western blot were consistent with the mRNA expression.

CONCLUSIONSHepaCAM can alter the gene expression profile of bladder cancer EJ cells. The well-known anti-tumor effect of hepaCAM may be mediated by regulating the gene expression via multiple pathways.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

OBJECTIVETo study the changes of adenosine diphosphate (ADP)-induced platelet aggregation rate, and evaluate the effects of Maixuekang Capsule (, MKC) on platelet aggregation rate and long-term prognosis of patients with acute coronary syndrome after percutaneous coronary intervention (PCI).

METHODSA total of 236 patients with acute coronary syndrome, who received successful PCI, were randomly assigned to a trial group (116 cases) and a control group (120 cases) according to random numbers; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent forms. In the trial group, the patients were treated with MKC combined with routine medication, and in the control group the patients were treated with routine medication. The therapeutic course for the two groups was 12 months and the follow-up was 12 months. The levels of ADP-induced platelet aggregation rate and serum high-sensitive C-reactive protein (hs-CRP) were determined before PCI, 12 h and 30 days after PCI. In the meantime, the incidence of cardio-/cerebrovascular events was recorded during the 12-month follow-up.

RESULTSCompared with before PCI, the levels of ADP-induced platelet aggregation rate and serum hs-CRP were significantly higher at 12 h after PCI (P<0.05). They were significantly reduced after 30-day-treatment of MKC, showing statistical differences when compared with those in the control group (P<0.05). During the 12-month follow-up, the incidence of cardio-/cerebrovascular events was significantly lower in the trial group than in the control group (6.9% vs. 12.5%, P<0.01).

CONCLUSIONSADP-induced platelet aggregation function was significantly elevated after PCI. MKC improved the prognosis of patients with acute coronary syndrome, possibly through inhibiting the platelet aggregation, fighting against inflammation, and protecting the vascular endothelial function.
