Objective To investigate the correlation of variations of ABCB11 gene and primary intrahepatic stone (PIS).Methods The retrospective case-control study was conducted.The clinical data of 319 patients with PIS and 344 healthy controls who were admitted to the Southwest Hospital of the Third Military Medical University between December 2012 and December 2015 were collected.Three hundred and ninteen patients with PIS and 344 healthy controls were respectively allocated into the PIS and control groups.Twenty-seven exons in ABCB11 gene were detected via polymerase chain reaction (PCR) and DNA sanger sequencing.Observation indicators included:(1) variations and genotype frequency distribution of ABCB11 gene in the 2 groups;(2) correlation analysis between variations of ABCB11 gene and clinical data of patients with PIS:preoperative indicators of liver function test,recurrent episodes of cholangitis,preoperative obstructive jaundice,type and recurrence of stones.Comparison between groups in variations and genotype frequency distribution of ABCB11 gene was analyzed by the Logistic regression.The Kruskal-Wallis H test was performed to explore the correlation between genotype of ABCB11 gene and clinical test results of patients with PIS.Correlation between genotype of ABCB11 gene and clinicopathological data of patients with PIS was analyzed by the chi-square test.Results (1) Variations and genotype frequency distribution of ABCB11 gene in the 2 groups:whole-exome sequencing results showed that synonymous mutations of rs3815675,rs2287616 and rs497692 and missense mutations of rs2287617,rs2287622 and rs118109635 in the PIS group were respectively detected in exon 4,9,24 and 9,13,21.CT genotype frequency of rs118109635 was 4.70％(15/319) in the PIS group and 1.45％ (5/344) in the control group,respectively,with a statistically significant difference [OR=3.49,95％ confidence interval (CI):1.17-10.40,P＜0.05].GG and AG+GG genotype frequency of rs497692 were 46.08％ (147/319),87.46％ (279/319) in the PIS group and 37.79％ (130/344),79.36％ (273/344) in the control group,respectively,with a statistically significant difference (OR=1.73,1.65,95％ CI:1.05-2.83,1.04-2.61,P＜0.05).(2) Correlation analysis between variations of ABCB11 gene and clinical data of patients with PIS:levels of glutamyl-transpeptidase (GGT),alkaline phosphatase (ALP) and direct bilirubin (DBil) in the PIS group were 167 U/L (range,7-1 968 U/L),166 U/L (range,36-1 527 U/L),4 μmol/L(range,1-272 μmol/L) in the CC genotype of rs118109635 and 433 U/L(range,17-864 U/L),232 U/L (range,85-613 U/L),6 μmol/L(range,2-173 μmol/L) in the CT genotype of rs118109635,respectively,with a statistically significant difference (H=6.025,5.879,8.056,P＜0.05).Globulin level of PIS group was respectively 32 g/L (range,20-40 g/L),34 g/L(range,17-50 g/L) and 33 g/L(range,14-49 g/L) in the AA,AG and GG genotype of rs497692,respectively,with a statistically significant difference (H=12.119,P＜0.05).Of 81 patients with recurrence of PIS,GG and GA genotypes of rs2287617 were detected in 78 and 3 patients,respectively,with a statistically significant difference (x2=5.367,P＜0.05);TT,TC and CC genotypes of rs2287622 were detected in 12,39 and 30 patients,respectively,with a statistically significant difference (x2=6.153,P＜0.05).Of 127 patients with obstructive jaundice,116 and 11 patients had CC and CT genotypes of rs118109635,respectively,with a statistically significant difference (x2=7.381,P＜0.05);11,43 and 73 patients had AA,AG and GG genotypes of rs497692,respectively,with a statistically significant difference (x2 =11.364,P＜0.05).Conclusion There is a correlation between rs118109635 and rs497692 of ABCB11 gene and PIS,meanwhile,the above variation loci are associated with obstruction of biliary tract and cholestasis.

Objective To evaluate the therapeutic methods and the key points in the management of delayed complications of bile duct stenosis after iatrogenic bile duct injuries.Methods Five patients with bile duct injuries developed delayed complications of bile duct stenosis after cholecystectomy were retrospectively studied.All clinical information were derived from the medical data of these 5 patients treated in our department from June 2002 to July 2006.Results Of the 5 patients with delayed complications of iatrogenic bile duct injuries,2 patients developed common bile duct occlusion,2 patients developed hilar bile duct stenosis,and 1 patient developed anastomotic stenosis after cholangiojejunostomy.Bile duct injuries occurred in 3 patients after laparoscopic cholecystectomy,and in another 2 patients after mini-laparotomy-cholecystectomy.The locations of the bile duct injuries,according to Strasberg classification,were type E1 (n=1),type E2 (n=1),type E3,(n=1),and type E5 (n=2).All 5 patients received PTCD initially to relieve obstructive jaundice and then they received surgical exploration and biliary reconstruction.These patients received cholangioplasty at the porta hepatis,and hepaticojejunostomy using a Roux-en-Y anastomosis.Two patients received Roux-en-Y anastomosis of the common hepatic duct to the jejunum.All these patients had good recovery and were discharged well postoperatively.All patients had been followed-up for 7 years or more,with no evidence of obstructive jaundice or biliary tract infection.Conclusions For patients who present with delayed complications of bile duct stenosis after iatrogenic bile duct injuries,primary PTCD is carried out to relieve jaundice and to control infection.Meticulous dissection of the porta hepatis,reliable anastomosis of the proximal healthy bile duct tissues to a jejunal loop,and adequate size of anastomosis guarantee success of surgery.

Anxiety disorder is one of the most common mental disorders and seriously impairs the physical and mental health of patients. Due to the efficacy of acupuncture for tranquilization, acupuncture displays its unique advantage on the treatment of anxiety disorder, but the relevant biological mechanism has not been elaborated. The modern medicine study has proved that the heart and brain have their own independent natriuretic peptide (NP) system. The dysfunction of ANP and its receptor are closely related to the occurrence of anxiety disorder. The ANP acts on anti-anxiety. Hence, focusing on the three aspects, named the anti-anxiety effect of acupuncture based on its tranquilizing effect, the anti-anxiety effect of ANP and the positive regulation of acupuncture on NP, the mechanism on ANP and its receptor was explored in anti-anxiety with acupuncture based on tranquilizing effect, and the idea was put forward on that the anti-anxiety effect of acupuncture was possibly based on its action of tranquilization through regulating the ANP and its receptor. As a result, it is expected to provide the theoretic support for the mechanism study on anti-anxiety with acupuncture based on its tranquilizing effect.

Objective To investigate the efficacy of different radical surgical procedures for the treatment of hilar cholangiocarcinoma.Methods The clinical data of 207 patients with hilar cholangiocarcinoma who were treated at the Southwest Hospital from June 2007 to June 2012 were retrospectively analyzed.Local resection or hemihepatectomy combined with caudate lobectomy was applied to patients with Bismuth type Ⅰ hilar cholangiocarcinoma; dumbbell type radical resection was applied to patients with Bismuth type Ⅱ hilar cholangiocarcinoma or some patients with type Ⅲ a,Ⅲ b and Ⅳ hilar cholangiocarcinoma; hemihepatectomy or extended hemihepatectomy combined with caudate lobectomy was applied to patients with Bismuth type Ⅲ a,Ⅲ b and Ⅳ hilar cholangiocarcinoma.The patients were followed up every 3 months postoperatively till December 2012.All data were analyzed using the chi-square test or Fisher exact probability test,the survival curve was drawn by Kaplan-Meier method,and the survival was analyzed using the Log-rank test.Results Of the 207 patients,124 received radical resection,including 14 received local resection,23 received dumbbell type resection,87 received lobectomy + caudate lobectomy,49 received palliative resection; 34 received biliary drainage.Four patients died perioperatively.The incidences of complications of dumbbell type radical resection,left hemihepatectomy + caudate lobectomy,right hemihepatectomy + caudate lobectomy were 21.7％ (5/23),46.6％ (27/58) and 48.3％ (14/29),respectively.The incidence of complications after dumbbell type radical resection was significantly lower than left hemihepatectomy + caudate lobectomy and right hemihepatectomy + caudate lobectomy (x2 =4.42,3.90,P ＜ 0.05).One hundred and seventy patients were followed up.The median survival time of the 112 patients who received radical radical resection was 26.5 months,and the 1-,3-,5-year survival rates were 75.9％ (85/112),42.9％ (24/56) and 28.9％ (11/38),respectively.The median survival time of the 38 patients who received palliative resection was 8.5 months,and the 1-,3-year survival rates were 31.6％ (12/38) and 0.The survival time of 20 patients who received biliary drainage was 4.0 months,and the l-year survival rate was 0.The survival rate of patients who received radical resection was significantly higher than those who received palliative resection (x2=65.32,P ＜ 0.05).There was a significant difference in the survival rate between patients who received surgical treatment and those who received biliary drainage (x2=99.97,P ＜ 0.05).Of the 112 patients who received radical resection,the median survival time of 10 patients who received local resection of tumor was 47.0 months,the 1-year survival rate was 10/10,and 4 patients survived at the end of the follow-up; the median survival time of 23 patients who received dumbbell type radical resection was 32.0 months,and the 1-,3-year survival rates were 95.7％ (22/23) and 7/15,and the survival time of 6 patients was longer than 5 years; the median survival time of 54 patients who received left hemihepatectomy or extended left hemihepatectomy + caudate lobectomy was 27.6 months,and the 1-,3-year survival rates were 42.1％ (24/57) and 38.7％ (12/32),and the survival time of 9 patients was longer than 5 years,3 patients survived at the end of the follow-up ; the median survival time of 25 patients who received right hemihepatectomy or extended right hemihepatectomy + caudate lobectomy was 28.3 months,and the 1-,3-year survival rates were 45.8％ (11/24) and 6/15,and the survival time of 6 patients was longer than 5 years,2 patients survived at the end of follow-up.The median survival time of 35 patients (patients with Bismuth type Ⅰ,Ⅱ hilar cholangiocarcinoma and Bismuth Ⅲ a and Ⅲ b hilar cholangiocarcinoma which did not invade the secondary bile duct) who received hemihepatectomy + caudate lobectomy was 32.0 months,and the 1-,3-,5-year survival rates were 91.4％ (32/35),45.8％ (11/24) and 5/16,which were not different from the survival rate of patients who received dumbbell type radical resection (x2 =0.17,P ＞ 0.05).The 5-year survival rate of patients with lymph node metastasis was 4/19,which was significantly lower than 30.4％ (7/23) of patients without lymph node metastasis (x2 =23.40,P ＜ 0.05).Conclusion Joint lobectomy and standardized lymph node dissection could help to improve the efficacy of surgical treatment for patients with hilar cholangiocarcinoma.

Objective To investigate the clinical significance of multiple tumor markers in the early diagnosis of cholangiocarcinoma.Methods 165 patients with histopathologically confirmed cholangiocarcinoma and 25 patients with gallstone canceration were enrolled in this study.36 patients with gallstones and 46 patients with bile duct stenosis were enrolled as controls.The determinations of multiple tumor markers,including carcinoembryonic antigen (CEA),CA125,CA153,CA242,CA19-9,alpha-fIetoprotein (AFP) and Ferritin,of all subjects and the imageological determinations of all the patients with cholangiocarcinoma and with gallstone canceration were analysed retrospectively.Comparisons between the groups were performed using the likelihood ratio test of the Chi-square test.Results CA19-9 had the highest sensitivity and specificity (83.6％ and 96.3％ respectively) for cholangiocarcinoma,and CA242 had a high sensitivity for gallstone canceration though it was not so sensitive in cholangiocarcinoma.Multiple tumor markers increased the sensitivity and specificity in the early diagnosis of cholangiocarcinoma.Compared with imageological determinations,multiple tumor markers had a higher sensitivity for the early diagnosis of cholangiocarcinoma with a tumor mass ＜1 cm.Conclusion Multiple tumor markers have important clinical values in the early diagnosis of cholangiocarcinoma.

Objective: To observe the effect of electroacupuncture (EA) on cytochrome c oxidase (COX)activity of hippocampal mitochondria in senescence-accelerated mouse prone 8 (SAMP8) mice, and to explore the EA mechanism on Alzheimer disease (AD) in improving energy metabolic disorder.
Methods: Twelve SAMP8 mice were randomly divided into a model group and an EA group, with six in each group. Six senescence-accelerated mouse resistance 1 (SAMR1) mice were prepared as blank group. Mice in the EA group received EA on Baihui (GV 20) and Yongquan (KI 1), once a day for 7 d as a course, altogether 3 courses with one day intervalbetween two courses. Mice in the model group and the blank group were manipulated and fixed as those in the EA group. After interventions, Morris water maze was employed to test spatial learning and memory ability to evaluate EA effect; spectrophotometry was used to detect the activity of hippocampal mitochondria COX.
Results: Compared with the blank group, mean escape latenciesof the EA group and model group were prolonged significantly in Morris water maze tests (P<0.01), the residue duration in the former platform quadrant significantly decreased (P<0.01). Compared with the model group, mean escape latencies on 1 d, 2 d and 3 d of the EA group were significantly reduced (P<0.05), and those on 4 d and 5 d continued the decreasing tendency (P<0.01), the residue duration on the former platform quadrant was significantly prolonged (P<0.05). The COX activity tests showed that, compared with the blank group, COX activities of the model group and the EA group were significantly decreased (P<0.01); compared with the model group, COX activity of the EA group was significantly elevated (P<0.01).
Conclusion: It’s plausible that EA improves AD learning and memory ability by increasing mitochondria COX activity, protecting the structure and function, and improving energy metabolism.

Objective To investigate the expression and significance of B lymphocyte stimulator (Blys) and its receptor BAFF (BAFF-R) in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods The expression of Blys and BAFF-R was measured by flow cytometry in 90 pa-tients with SLE,which was compared with that of 45 healthy controls. The relationships between the expression of Blys, BAFF-R and other laboratory parameters as well as disease activity were analyzed. Results The expression of Blys and BAFF-R in PBMCs from patients with SLE was significantly elevated compared to healthy controls (P <0.001), so did the active group (P < 0.001) and inactive group (P < 0.001 and P < 0.01). The expression of Blys in PBMCs from active SLE patients was higher than that of inactive patients (P <0.05). However,there was no statisti-cal difference of BAFF-R between the two groups. The expression of Blys in PBMCs was positively related to SLEDAI (r =0.728,P <0.001) ,IgG and IgM(r=0.691,P<0.001 and r =0.453,P<0.01) ,but negatively related to C3 and CA (r = -0.510, P < 0.001 and r = -0.312, P < 0.05). The expression of Blys in dsDNA positive group was higher than those of dsDNA negative group (P < 0.01). The expression of Blys and BAFF-R in Cl qAb positive group was higher than those of ClqAb negative group as well (P <0.01). Conclusion The expression of Blys and its receptor BAFF-R in PBMCs from SLE is elevated ,which may reflect the disease activity and is related to the pro-duction of autoantibody. They might be involved in the pathogenesis of SLE.

Data analysis poses a significant challenge to the large-scale proteomics studies. Based on the structured and controlled vocabularies-Gene Ontology (GO), and the GO annotation from related databases, a strategy composed of several programs and local databases is developed to identify the functional distribution and the significantly enriched functional categories of the proteomic expression profile. It would be helpful for understanding the overall functions of these identified proteins and supply the fundamental information for further bioinformatics exploration. This strategy has been successfully used in the Human Fetal Liver (HFL) proteomic research, which is available online at http://www.hupo.org.cn/GOfact/.
