Abstract
Objectives: To analyze the survival benefit of intrahepatic cholangiocarcinoma (ICC) radical resection based on single cell omics. Methods: This is a retrospective case-series study. ICC single-cell sequencing was integrated from four data sets in the Gene Expression Omnibus Database, with a total of 46 patients undergoing radical resection, to explore the characteristics of the microenvironment. Microarray data of 100 ICC cases was analyzed in the EMBI database with survival data. The infiltration abundance of each epithelial cell cluster was calculated in each microarray data sample using the ssGSEA algorithm. The key epithelial cell cluster associated with poor patient outcomes was explored. The clinical value of key marker genes in this subgroup was studied. Prognostic marker genes were selected using the univariate and multivariate Cox proportional hazards(CoxPH) model. The The CoxPH model was constructed by the target genes and a nomogram was drawn. Kaplan-Meier survival analysis was used to verify the relationship between score and prognosis of patients. The predictive power of the model was evaluated by receiver operating characteristic(ROC) curves, calibration curves, and decision curve analysis (DCA). Results: Epithelial cell clusters infiltrated almost exclusively in tumor tissue. The MT2A+ epithelial cell subset was associated with a poorer prognosis for patients with a high invasion abundance and patients characterized by infiltration of this group were defined as antioxidant. After screening marker genes in this cluster using a univariate and multivariate CoxPH model, the following genes were found to be independent prognostic factors: FILPIL, NFKBIA, PEG10, SERPINB5. The CoxPH model was constructed using the four gene expression levels, and the survival rate of patients in the high-risk group was significantly lower than those in the low-risk group (all P<0.05). The constructed nomogram had good discrimination and validity. The ROC curve showed that the predicted area under the curve was 0.779, 0.844 and 0.845 at 1, 3 and 5 years, respectively. Compared to clinical indicators, the model had better predictive power using the calibration curve and the DCA test. Conclusions: The MT2A+ epithelial cell group may be associated with the prognosis of patients with ICC, and the concept of ICC tissue typing of antioxidant and non-antioxidant types is proposed. The type of antioxidant may predict the poor prognosis of the patients, and postoperative adjuvant therapy and other means could be considered to improve the survival of the patients.

Abstract
Intrahepatic cholangiocarcinoma (ICC) is a type of primary liver cancer, which has shown an increasing trend in incidence and mortality in recent years, with a poor prognosis. The clinical diagnosis and treatment of ICC currently face the challenges of low detection rate, high mortality rate, poor treatment outcome, and urgently need more in-depth research to promote the improvement of clinical diagnosis and treatment level. In recent years, ICC diagnosis and treatment related research has made new progress in many aspects, and the knowledge about these new clinical diagnosis and treatment advances should be updated in a timely manner. This article reviewed the latest research results in recent years, summarized some new views on ICC typing, prevention and diagnosis staging that have been proposed recently, as well as the new progress made in surgical treatment and systemic treatment, and briefly discussed the potential of ICC individualized precision treatment and the occurrence of rare complications caused by combined treatment.

Abstract
Objective: To establish a predictive model for survival benefit of patients with intrahepatic cholangiocarcinoma (ICC) who received adjuvant chemotherapy after radical resection. Methods: The clinical and pathological data of 249 patients with ICC who underwent radical resection and adjuvant chemotherapy at 8 hospitals in China from January 2010 to December 2018 were retrospectively collected. There were 121 males and 128 females,with 88 cases>60 years old and 161 cases≤60 years old. Feature selection was performed by univariate and multivariate Cox regression analysis. Overall survival time and survival status were used as outcome indicators,then target clinical features were selected. Patients were stratified into high-risk group and low-risk group,survival differences between the two groups were analyzed. Using the selected clinical features, the traditional CoxPH model and deep learning DeepSurv survival prediction model were constructed, and the performance of the models were evaluated according to concordance index(C-index). Results: Portal vein invasion, carcinoembryonic antigen>5 μg/L,abnormal lymphocyte count, low grade tumor pathological differentiation and positive lymph nodes>0 were independent adverse prognostic factors for overall survival in 249 patients with adjuvant chemotherapy after radical resection (all P<0.05). The survival benefit of adjuvant chemotherapy in the high-risk group was significantly lower than that in the low-risk group (P<0.05). Using the above five features, the traditional CoxPH model and the deep learning DeepSurv survival prediction model were constructed. The C-index values of the training set were 0.687 and 0.770, and the C-index values of the test set were 0.606 and 0.763,respectively. Conclusion: Compared with the traditional Cox model, the DeepSurv model can more accurately predict the survival probability of patients with ICC undergoing adjuvant chemotherapy at a certain time point, and more accurately judge the survival benefit of adjuvant chemotherapy.

Abstract
Objectives: To construct a nomogram for prediction of intrahepatic cholangiocarcinoma (ICC) lymph node metastasis based on inflammation-related markers,and to conduct its clinical verification. Methods: Clinical and pathological data of 858 ICC patients who underwent radical resection were retrospectively collected at 10 domestic tertiary hospitals in China from January 2010 to December 2018. Among the 508 patients who underwent lymph node dissection,207 cases had complete variable clinical data for constructing the nomogram,including 84 males,123 females,109 patients≥60 years old,98 patients<60 years old and 69 patients were pathologically diagnosed with positive lymph nodes after surgery. Receiver operating characteristic curve was drawn to calculate the accuracy of preoperative imaging examinations to determine lymph node status,and the difference in overall survival time was compared by Log-rank test. Partial regression squares and statistically significant preoperative variables were screened by backward stepwise regression analysis. R software was applied to construct a nomogram,clinical decision curve and clinical influence curve,and Bootstrap method was used for internal verification. Moreover,retrospectively collecting clinical information of 107 ICC patients with intraoperative lymph node dissection admitted to 9 tertiary hospitals in China from January 2019 to June 2021 was for external verification to verify the accuracy of the nomogram. 80 patients with complete clinical data but without lymph node dissection were divided into lymph node metastasis high-risk group and low-risk group according to the score of the nomogram among the 858 patients. Log-rank test was used to compare the overall survival of patients with or without lymph node metastasis diagnosed by pathology. Results: The area under the curve of preoperative imaging examinations for lymph node status assessment of 440 patients was 0.615,with a false negative rate of 62.8% (113/180) and a false positive rate of 14.2% (37/260). The median survival time of 207 patients used to construct a nomogram with positive or negative postoperative pathological lymph node metastases was 18.5 months and 27.1 months,respectively (P<0.05). Five variables related to lymph node metastasis were screened out by backward stepwise regression analysis,which were combined calculi,neutrophil/lymphocyte ratio,albumin,liver capsule invasion and systemic immune inflammation index,according to which a nomogram was constructed with concordance index(C-index) of 0.737 (95%CI: 0.667 to 0.806). The C-index of external verification was 0.674 (95%CI:0.569 to 0.779). The calibration prediction curve was in good agreement with the reference curve. The results of the clinical decision curve showed that when the risk threshold of high lymph node metastasis in the nomogram was set to about 0.32,the maximum net benefit could be obtained by 0.11,and the cost/benefit ratio was 1∶2. The results of clinical influence curve showed that when the risk threshold of high lymph node metastasis in the nomogram was set to about 0.6,the probability of correctly predicting lymph node metastasis could reach more than 90%. There was no significant difference in overall survival time between patients with high/low risk of lymph node metastasis assessed by the nomogram and those with pathologically confirmed lymph node metastasis or without lymph node metastasis (Log-rank test:P=0.082 and 0.510,respectively). Conclusion: The prediction accuracy of preoperative nomogram for ICC lymph node metastasis based on inflammation-related markers is satisfactory,which can be used as a supplementary method for preoperative diagnosis of lymph node metastasis and is helpful for clinicians to make personalized decision of lymph node dissection for patients with ICC.

Abstract
Biliary tract cancer is extremely malignant with a poor prognosis. At the moment, the only curative method available is radical resection. Targeted and immunotherapy are currently advancing quickly, but chemotherapy still holds a key role in the perioperative management of biliary cancer. Perioperative chemotherapy aims to decrease tumor volume before surgery so that patients can have their tumors surgically removed or have a higher radical resection rate. It also aims to remove any tumor cells that remain after surgery and prevent the growth of new tumors. Chemotherapy-based combination treatment techniques have been increasingly investigated in recent years to improve perioperative care and patient survival. From the standpoint of chemotherapy regimens and clinical trial success in the perioperative phase of radical surgery, the value of chemotherapy in the perioperative period of biliary tract cancer were explored in this paper.

Abstract
Biliary tract cancer has insidious onset and high degree of malignancy, and radical resection is often impossible when it is diagnosed.Conversion therapy can achieve tumor downgrading, so that patients who were initially unresectable have a chance to achieve R0 resection.However, due to the high heterogeneity and complex immune microenvironment of biliary tract cancer, conversion therapy is still in the stage of active exploration.As a new type of conversion therapy, combination of targeted therapy and immunotherapy is of great significance to effectively improve the efficiency of conversion therapy.Further exploration of combination mechanism and improvement of immune microenvironment are expected to become the future direction of combination of targeted therapy and immunotherapy.

Abstract
Biliary tract cancer is found in the middle and advanced stages mostly and patients will deprive surgical indications. Conversion therapy can make the stage of some patients down and thus make radical resection feasible. Biliary tract cancer is highly heterogeneous in clinical features, cell origin, histology, molecular biology and other aspects, resulting in a lack of specific and effective conversion therapy strategies. Currently, it is the important development direction to evaluate and classify different individual conditions and select individualized conversion therapy regimens. With the deepening of the research on the pathogenesis and the improvement of treatment protocols, the future conversion therapy will undoubtedly develop towards the direction of individualization and precision.

Abstract
Objective: To investigate the pathogens' distribution and antimicrobial resistance in the bile of acute biliary tract infection patients. Methods: The data of bile bacterial culture and drug sensitivity test of 223 acute biliary tract infection patients who underwent gallbladder puncture or endoscopic retrograde cholangiopancreatography drainage from July 2009 to July 2019 were analyzed retrospectively at Department of General Surgery,Xinhua Hospital,Affiliated to Shanghai Jiao Tong University School of Medicine.There were 141 males and 82 females with age of 67.3 years(range:28 to 93 years).Three to five milliliter of bile was extracted from each patient and sent to the laboratory for bacterial culture,identification and drug sensitivity test.The patients were divided into two groups according to the visiting time: the former group (n=124) was admitted from July 2009 to July 2014,and the latter group(n=99) was admitted from August 2014 to July 2019.The distribution of pathogenic bacteria and the changing trend of drug resistance rate of common bacteria in the two groups were compared.The results of drug sensitivity test were analyzed by WHONET software provided by WHO bacterial surveillance network.The drug resistance rates in different time periods were compared by χ2 test. Results: In this study,there were 147 cases of acute cholangitis and 76 cases of acute cholecystitis.A total of 376 strains of pathogenic bacteria were cultured.Among them,98 strains(26.1%) were gram-positive bacteria,269 strains(71.5%) were gram-negative bacteria and 9 strains(2.4%) were fungi.The top three gram-positive bacteria were Enterococcus faecium (49.0%,48/98),Enterococcus faecalis(20.4%,20/98),and Enterococcus luteus(7.1%,7/98).The top 5 gram-negative bacteria were Escherichia coli(33.5%,90/269),Klebsiella pneumoniae(13.8%,37/269),Pseudomonas aeruginosa(13.0%,35/269),Acinetobacter baumannii (12.6%,34/269),and Enterobacter cloacae(4.8%,13/269).From 2009 to 2019,there was no significant change in the proportion of gram-positive bacteria (former group vs. latter group: 25.3% vs. 28.2%) and gram-negative bacteria(former group vs.latter group: 74.7% vs. 71.8%) in the bile of patients with acute biliary tract infection.Gram-positive bacteria were mainly Enterococci(85.7%,84/98) and gram-negative bacteria were Escherichia coli(33.5%,90/269).Acinetobacter baumannii accounted for 7.8%(11/142) of gram-negative bacteria in the former group and 18.1%(23/127) in the latter group,an increase of 10.3% over previous five years.Pseudomonas aeruginosa had a downward trend,16.9% in the former group(24/142) and 8.7% in the latter group (11/127),the proportion decreased by 8.2%,and the other changes were not significant.The drug resistance rates of common gram-positive bacteria were relatively stable,and the drug resistance rates of Enterococcus faecium to many antibiotics were higher than those of Enterococcus faecalis.The resistance rates of gram-negative bacteria to most antibiotics showed an upward trend,among which Klebsiella pneumoniae showed an upward trend to most of antibiotics(former group: 0/15-4/13, latter group: 55.0%-70.0%; χ2=3.996-16.942, P=0.000-0.046).The drug resistance rates of Acinetobacter baumannii was generally higher,but there were no significant changes in the drug resistance rates of Acinetobacter baumannii between the two groups.The drug resistance rates of Pseudomonas aeruginosa to most antibiotics increased,and the overall drug resistance rates of Escherichia coli were stable and showed a slight upward trend. Conclusions: The main pathogens in bile of patients with acute biliary tract infection are gram-negative bacteria.The constituent ratio of various gram-negative bacteria had no significant change from 2009 to 2019,but the drug resistance rates shows an upward trend.Among the gram-negative bacteria, Escherichia coli is the most important pathogen,and the proportion has no significant change.The proportion of Acinetobacter baumannii in the former group was significantly higher than that in the former group.And the proportion of Pseudomonas aeruginosa has a decreased trend.

Abstract
Objective: To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China. Methods: This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed. Results: Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn't be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%. Conclusions: More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

Abstract
Incidental gallbladder cancer(IGBC) originated in the West more than half a century ago.IGBC was translated and introduced into China afterwards with widespread clinical application.With the popularization of laparoscopic cholecystectomy, the trend of "abuse" of IGBC has become increasingly apparent worldwide.Many advanced gallbladder cancers have been categorized as IGBC which actually become the synonym of "missed diagnosis" . From the point of the pathology, the diagnosis of IGBC may cause delays in treatment and adversely affect the patient's prognosis.For country like China with relatively high incidences of chronic cholecystitis, cholelithiasis, and gallbladder cancer, the concept of IGBC, however, is no longer applicable to our diagnosis treat model.For improving the prognosis of gallbladder patients, it is necessary to update and rename the concept of IGBC and more attention should be paid to improve the diagnostic level of early stage tumor.

Abstract
Gallbladder carcinoma(GBC) is one of the most malignant cancers of the digestive system with very poor prognosis due to its histopathological features of easy invasion to the liver, early lymph node metastasis and nerve infiltration, which result in low resection rate. It has been confirmed that radical surgery only makes sense to relatively early GBC in improving prognosis of patients. Therefore, based on recognition of biological characteristics of GBC and the theories of oncology, efforts should be focused on developing various adjuvant treatment methods for treating GBC including chemotherapy, radiotherapy, targeted therapy and immunotherapy.

Abstract
Intrahepatic cholangiocarcinoma(ICC) is the second common primary liver cancer originated from epithelium of the sub-branches of intrahepatic bile ducts with extremely poor prognosis and lack of effective treatment.The prognosis of ICC is mostly affected by the origin,the type and the size of the tumor as well as the intrahepatic metastasis(satellite lesion) and lymph node metastasis etc.Surgical resection remains the first choice of treatment to patients with ICC.However, there are multiple issues in surgical treatment of ICC, which have not been reached a consensus.Among them, the value of systematic lymphadenectomy during hepatic resection for ICC patient remains one of the hot spot issues.Given the heterogeneity of ICC,we recommend planning the procedure of the radical resection and lymphadenectomy personally, according to the type and origin of the tumor, the number and locationof the lesion.The pre-operation imaging examination and the intra-operation lymph node tracing technique could provide valuable information to help the surgeon decide the range of systematic lymphadenectomy.Routine systematic lymphadenectomy is recommended in the surgical treatment of ICC patients by experienced surgeons even without evidence of lymph node metastasis.The resected lymph tissue should be labeled by the provenance for further study.

Abstract
Objectives: To propose a novel clinical classification system of gallbladder cancer, and to investigate the differences of clinicopathological characteristics and prognosis based on patients who underwent radical resection with different types of gallbladder cancer. Methods: The clinical data of 1 059 patients with gallbladder cancer underwent radical resection in 12 institutions in China from January 2013 to December 2017 were retrospectively collected and analyzed.There were 389 males and 670 females, aged (62.0±10.5)years(range:22-88 years).According to the location of tumor and the mode of invasion,the tumors were divided into peritoneal type, hepatic type, hepatic hilum type and mixed type, the surgical procedures were divided into regional radical resection and extended radical resection.The correlation between different types and T stage, N stage, vascular invasion, neural invasion, median survival time and surgical procedures were analyzed.Rates were compared by χ(2) test, survival analysis was carried by Kaplan-Meier and Log-rank test. Results: Regional radical resection was performed in 940 cases,including 81 cases in T1 stage,859 cases in T2-T4 stage,119 cases underwent extended radical resection;R0 resection was achieved in 990 cases(93.5%).The overall median survival time was 28 months.There were 81 patients in Tis-T1 stage and 978 patients in T2-T4 stage.The classification of gallbladder cancer in patients with T2-T4 stage: 345 cases(35.3%)of peritoneal type, 331 cases(33.8%) of hepatic type, 122 cases(12.5%) of hepatic hilum type and 180 cases(18.4%) of mixed type.T stage(χ(2)=288.60,P<0.01),N stage(χ(2)=68.10, P<0.01), vascular invasion(χ(2)=128.70, P<0.01)and neural invasion(χ(2)=54.30, P<0.01)were significantly correlated with the classification.The median survival time of peritoneal type,hepatic type,hepatic hilum type and mixed type was 48 months,21 months,16 months and 11 months,respectively(χ(2)=80.60,P<0.01).There was no significant difference in median survival time between regional radical resection and extended radical resection in the peritoneal type,hepatic type,hepatic hilum type and mixed type(all P>0.05). Conclusion: With application of new clinical classification, different types of gallbladder cancer are proved to be correlated with TNM stage, malignant biological behavior and prognosis, which will facilitate us in preoperative evaluation,surgical planning and prognosis evaluation.

Abstract
Hilar cholangiocarcinoma is one of the most difficult malignant tumors to treat in the biliary system. In Japan, 5-year survival rate of the disease has increased from 32.5% to 67.1% during the past 30 years. The impressive progress reflects the solid efforts in preoperative endoscopic diagnosis, innovation in surgery such as PTPE as well as hepato-pancreatoduodenectomy and perioperative treatment including replacement of the bile and synbiotic treatment, which have finally formed a set of standardized diagnosis and treatment systems. The present review intends to report the history, current status and remaining bottlenecks of the diagnosis and treatment system of hilar cholangiocarcinoma in Japan as follows.

Abstract
Intrahepatic cholangiocarcinoma(ICC) is generally found late along with extremely poor prognosis and lack of effective and standardized treatment. Tremendous heterogeneities exist in onset factors, geographic distribution, clinical manifestation, and biological characteristics of ICC patients. However, the relevant causes and mechanisms have not been clearly illustrated. Recent studies indicate that the diverse celluar origins of ICC, including liver cells, bile duct epithelial cells, glandular cells around the duct, and liver stem cells, etc. Besides, the tumorigenesis, progression and metastasis of ICC are closed related to metabolism such as glucose, lipid metabolism. It can be inferred that the varieties of biological characteristics and clinical manifestation of ICC patients are possibly closely linked with heterogeneous cellular origins, multiple metabolic mechanisms or pathways. Therefore, it's necessary to conduct research with regard to the connection between cellular origins, cell metabolism and clinical manifestation, biological characteristics, and make further classifications. Based on the accurate classification, surgeons can exert corresponding surgical and comprehensive treatment strategies on ICC patients, attaining the goal of individualized and standardized treatment, ultimately, improving prognosis and prolonging survival time.

Abstract
The high mobility group box 1 (HMGB1) as a conserved non-histone nuclear protein has been involved in a variety of biological processes of cancer, such as cell proliferation, apoptosis, angiogenesis and metastasis. Despite the increased expression of HMGB1 in many malignant tumors, the functions and molecular mechanisms by which HMGB1 contributes to the formation of hemangioma (HA) remain unclear. In the present study, immunohistochemistry was used to detect the expression levels of HMGB1 in different phases of human HAs. Cell function experiments, including MTT, cell colony formation and flow cytometry analysis were performed to evaluate the effects of HMGB1 knockdown on cell proliferation and apoptosis in HA CRL-2586 EOMA cells. As a consequence, we found that HMGB1 expression was significantly increased in proliferating phase HAs compared with the involuting phase HAs and normal skin tissues (P less than 0.01). Moreover, knockdown of HMGB1 gene in vitro suppressed EOMA cell proliferation and colony formation and induced cell apoptosis and cycle arrest at G0/G1 phase by downregulation of PCNA, CyclinD1, p-AKT and upregulation of p53 and cleaved PARP. Taken together, our findings demonstrate that HMGB1 may be implicated in the formation of HA through upregulation of AKT pathway, and represent a potential therapeutic target for treating HA.

Abstract
Angiogenesis is a process of development and growth of new capillary blood vessels from pre-existing vessels. Angiogenic growth factors play important roles in the development and maintenance of some malignancies, of which vascular endothelial growth factor (VEGF)/VEGFR2 interactions are involved in proliferation, migration, and survival of many cancer cells. The aim of this study was to investigate the function of VEGFR2 in human hemangiomas (HAs). Using immunohistochemistry assay, we examined the expression levels of VEGF, VEGFR2, Ki-67, glucose transporter-1 (Glut-1), phosphorylated protein kinase B (p-AKT) and p-ERK in different phases of human HAs. Positive expression of VEGF, VEGFR2, Ki-67, Glut-1, p-AKT and p-ERK was significantly increased in proliferating phase HAs, while decreased in involuting phase HAs (P=0.001; P=0.003). In contrast, cell apoptotic indexes were decreased in proliferating phase HAs, but increased in involuting phase HAs (P<0.01). Furthermore, we used small hairpin RNA (shRNA)-mediated VEGFR2 knockdown in primary HA-derived endothelial cells (HemECs) to understand the role of VEGF/VEGFR2 signaling. Knockdown of VEGFR2 by Lv-shVEGFR2 inhibited cell viability and induced apoptosis in primary HemECs companied with decreased expression of p-AKT, p-ERK, p-p38MAPK and Ki-67 and increased expression of caspase-3 (CAS-3). Overexpression of VEGFR2 promoted cell viability and blocked apoptosis in Lv-VEGFR2-transfected HemECs. Taken together, our findings demonstrate that, increased expression of VEGFR2 is involved in the development of primary HemECs possibly through regulation of the AKT and ERK pathways, suggesting that VEGFR2 may be a potential therapeutic target for HAs.

Abstract
Despite improvements in immunosuppressive therapy, acute rejection remains an important cause of morbidity and late graft loss in patients undergoing liver transplantation. Increasing evidence supports an important role for chemokines and their receptors in transplant immunology. An acute liver graft rejection model in rats was used to study the role of the chemokine receptor CXCR3 in acute transplant rejection after liver transplantation by lentivirus-mediated gene transfer of small interfering RNA (siRNA) against CXCR3. Using reverse transcription-polymerase chain reaction it was first shown that three lentivirus-CXCR3 siRNA vectors inhibited the in vitro expression of CXCR3 in activated T-cells bearing CXCR3. Then, it was shown that treatment of the animals with lentivirus-CXCR3 siRNA before liver transplantation reduced CXCR3 mRNA and protein, and protein levels of interleukin (IL)-2, IL-4, IL-6 and IL-10 and interferon-gamma measured as indices of acute graft rejection. Based on the results from this animal model, targeting chemokines by the use of siRNA may become a feasible option for therapy after transplantation.

Abstract
Through a facile solvothermal route using zinc chloride and thiourea as reactants, wurtzite ZnS and its precursor ZnS . (en)0.5 (en = ethylenediamine) with various morphologies and sizes were grown, which were characterized by XRD, SEM, TEM and N2 adsorption and so on. The phase evolution, composition and morphologies of the products are highly dependent on the concentration of en. By keeping the en-water volume ratio at 1/2 to 1, the nanostripes-flower or nanorod-spheric wurtzite ZnS were easily obtained under 120 degrees C for 6-24 h, which possess relatively higher specific surface area and larger total pore volume.

Abstract
BACKGROUND Gallbladder cancer is a common and lethal digestive malignancy which is nonsensitive to routine chemotherapy. Doxorubicin (DOX) is one of the major chemotherapeutic drugs for patients with gallbladder cancer. We tried to evaluate if combined use of somatostatin (SST) and DOX could have synergistic effect in the treatment of gallbladder cancer. METHODS Cells from the human gallbladder cancer cell line GBC-SD were treated with SST. Cell cycle analysis was determined by flow cytometry. Western blot analysis was performed to determine the protein levels of topoisomerase IIalpha (Topo IIalpha) after SST treatment. RT-PCR was utilized to detect SST receptors in GBC-SD cells. Finally, the chemotherapeutic effect of DOX combined with SST treatment on cellular growth was measured by MTT assay. RESULTS SST could induce cell cycle arrest in S phase and upregulate Topo IIalpha expression in GBC-SD cells. GBC-SD cells expressed all 5 subtypes of SST receptors. Finally, combined use of DOX with SST had a synergistic cytotoxic effect on GBC-SD cells. CONCLUSION SST, a naturally occurring, nontoxic compound, may represent a novel adjuvant chemotherapeutic agent for patients with gallbladder cancer.

Abstract
CeF(3):Tb(3+) nanoparticles (short pillar-like morphology with an average length and width of 11 and 5 nm, respectively) were successfully prepared by a polyol process using diethyleneglycol (DEG) as solvent. After being functionalized with a SiO(2)-NH(2) layer, these CeF(3):Tb(3+) nanoparticles can be conjugated with biotin molecules (activated by thionyl chloride) and further with avidin. The as-formed CeF(3):Tb(3+) nanoparticles, CeF(3):Tb(3+) nanoparticles functionalized with amino groups, biotin conjugated amino-functionalized CeF(3):Tb(3+) nanoparticles and biotinylated CeF(3):Tb(3+) nanoparticles bonded with avidin were characterized by x-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), UV/vis absorption spectra and luminescence spectra, respectively. The biofunctionalization of the CeF(3):Tb(3+) nanoparticles has less effect on their luminescence properties, i.e. they still show strong green emission (from Tb(3+), with (5)D(4)-(7)F(5) at 543 nm as the most prominent group), indicative of the great potential for these CeF(3):Tb(3+) nanoparticles to be used as biological fluorescence probes.

Abstract
BACKGROUND Tumor suppressor genes were studied in gallbladder disease including cancer for correlation. VEGF (vascular endothelial growth factor) expression was assessed against Nevin staging and metastasis of gallbladder carcinoma. The importance of p53, p16, and VEGF in gallbladder cancer was estimated. STUDY DESIGN Twenty-four gallbladder carcinomas, 20 gallbladder adenomas, and 18 chronic cholecystitis specimens were immunohistochemically and histopathologically investigated for the relation of p53, p16, and VEGF to Nevin staging and pathologic grading. RESULTS The expression rate of abnormal p53 in gallbladder carcinomas was significantly higher than that in gallbladder adenoma and chronic cholecystitis (p = 0.003, p = 0.014). The expression rate of abnormal p53 in Nevin staging S1, S2, S3 gallbladder carcinoma was significantly higher than that in S4, S5 (p = 0.01). Abnormal p16 was highest in carcinoma, next in adenoma, and lowest in chronic cholecystitis (p = 0.031, p = 0.017). Gallbladder carcinoma expressed VEGF far more often than adenoma or cholecystitis (p = 0.001); VEGF-positive rates were lower in S1, S2, S3 than S4, S5 by Nevin staging of gallbladder cancer (p = 0.044). CONCLUSION Mutation of p53 and p16 genes might correlate with progression of of gallbladder carcinoma. Analysis of p53 and p16 can estimate the prognosis of gallbladder cancer. VEGF expression correlates with Nevin staging in gallbladder cancer.
