SLE-like syndrome in (C57BL/6 x BALB/c) F1 mice can be induced by intravenous injection of lymphocytes from BALB/c parental mice. In these SLE-like mice levels of DNA antibody and anti—histone increased and there were immuno-complex mediated proteinuria, glomerulonephritis. 28 days later artesunate was given intraperitoneally to daily these mice. The results revealed that artesunate could significantly suppress the progression of disease activity,

China is among the middle-high endemic regions of HBV infection.The pathological outcomes of chronic HBV infection have been shown to be greatly influenced by several important factors,including HBV genotype,sub-genotype and gene viability mutation.HBV genome mutation,on the one hand,could alter its replication and secretion and thus change viral pathogenicity.In addition,host immune microenvironment and host-virus interaction,disease progression and the effect of antiviral therapy could be adapted at the same time.The detection of HBV genotypes,genetic subtypes and the key hotspot mutation is helpful to clinical risk assessment and prognosis prediction of HBV-related end-stage liver diseases (cirrhosis and hepatocellular carcinoma),it is also helpful to auxiliary predict the liver diseases recurrence and metastasis after treatment.Thus persistent care should be taken on the HBV mutation and its clinical translation so as to provide solid evidences for the personalized,standardized and fine management of HBV-related liver diseases.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China because of high incidence of hepatitis B virus (HBV) infection.HCC is diagnosed at a late stage in most of the cases; therefore the prognosis of patients with HCC is generally poor.Early diagnosis and surgical treatment are of great clinical desirable to improve prognosis of HCC.Tumor marker is an effective means for early diagnosis,prognosis assessment and recurrence monitoring.In addition to alpha fetoprotein (AFP),Lens culinaris agglutinin-reactive AFP (AFP-L3),des-γ-carboxy prothrombin (DCP),glypican-3,N-glycome markers,candidate-susceptibility genes,microRNAs and several other biomarkers have been revealed as potential HCC markers and will be applied in clinical laboratory gradually.In this review,the efficacies of novel HCC markers and their possible implications for clinical application are described.

Primary liver cancer (PLC) is the second leading cause of cancer death in China,and is one of the most serious threats to people's health.Early diagnosis and treatment can significantly improve the prognosis of PLC.Abnormal glycosylation is reported to be closely related to the genesis and development of malignant tumors.With the advent of modern proteomic and glycomic methodologies,several alterations in fucosylation,sialylation,and glycan branching have been observed in serum of patients with PLC.Altered glycosylation profiles,glycosyltransferases and glycosylated proteins could be screened and used as potential serum markers for early diagnosis,progression monitoring and prognosis evaluation of PLC.

The natural history of chronic HBV infection is diverse and variable, ranging from inactive carriers to progressive chronic hepatitis B ( CHB), cirrhosis and hepatocelluar carcinoma.It is estimated that 93 million people are chronically infected with HBV and 20 million cases suffering from chronic hepatitis B in China.Hepatocelluar carcinoma has been the second leading cause of death for male in China.Liver cirrhosis and HCC which have high mortality and morbidity have become the heavy burden for the limited medication resource of China.Here the current clinical applications and consensus progression based on antigen and nuclear acid detection were acknowledged.The reasonable application as well as appropriate clinical interpretation are emphasized indicating that laboratory medicine practitioners should be more actively involved in clinical diagnosis and treatment.More efforts and contributions should be made by the laboratory medicine practitioner for optimizing clinical management of HBV-related diseases in future.

Hepatocellular carcinoma(HCC) is the fifth most common cancer and the third cause of cancer-related death worldwide;meanwhile,it is also one of the fastest growing malignancies.The causes of HCC are multiple;HBV is the most important cause in China,with about 25%-30% of HBV infection patients finally develop hepatic cirrhosis and liver cancer.At present,large scale epidemiological studies revealed that the metabolic syndrome(MS) was closely related to liver cancer,and it even served as an independent risk factor for the occurrence and progression of liver cancer.Non-alcoholic fatty liver disease is a metabolic syndrome clinically manifested in the liver;recently it has been indicated to be closely related with HCC development and progression.This paper reviews the recent researches on metabolic syndrome and liver cancer,so as to provide literature for preventive and therapeutic studies on non-virus-related liver cancer.

Objective To study the operative design, safety evaluation and feasibility of gasless laparoscopic operations. Methods The gasless laparoscopic devices (GLD) were applied to 124 cases of laparoscopic choledocholithotomy with T-tube drainage, 56 cases of laparoscopic choledocholithotomy with primary bile duct suture, 1 case of laparoscopic choledochocystectomy hepaticojejunostomy, 15 cases of modified gasless laparoscopic choledochojejunostomy, 1 case of hand-assisted laparoscopic megalosplenic resection and portozygos disconnection, and 1 case of gasless device assisted laparoscopic splenectomy. Results All the operations were successfully conducted, without any severe complications. Follow-up for 1~9 years in 129 cases of biliary duct operations found 1 case of recurrence. Follow-up for 3~12 months in 2 cases of splenic operations found no recurrence. Conclusions Gasless laparoscopic operations in this study have reached minimally invasive outcomes, proven to be safe and feasible.

Objective To study the mRNA expression and function of TGF-?1, TGF-?RⅡ and CD105 in the lesional, non-lesional skin of psoriasis and of normal human skin. Methods The RNA of skin tissue was extracted using single-step method of RNA isolation by acid guanidinium thiocyanate. Reverse transcription polymerase chain reaction (RT-PCR) was used to measure the expression of mRNA. Results The mRNA expression of TGF-?1 and TGF-?RⅡ was lower in the epidermis of psoriatic lesion than that of non-lesional psoriatic and normal human skin(P

Objective To approach the feasibility of identifying the specific biomarker of ovarian cancer by SELDI TOF mass spectrometry. Methods The relative contents of serum protein of both 24 the patients with ovarian cancer and 56 cases of healthy people were tested by IMAC3 chip and proteinchip reader (CipherGen Inc., VS). Results On the M/Z values ranged from 4000Da to 10000Da, there were six kinds of protein contents in the serum of the were obviously different between the two groups. Among them the serum protein of M/Z value 4472Da may be regarded as a specific biomarker of ovarian cancer. In the learning mode, all the 24 patients and 56 control people were diagnosed and distinguished out correctly, while in the test mode, 23 patients were correctly diagnosed and 56 control people were distinguished out, the total accuracy was 98 75%(79/80), and the sensitivity and specificity were 95 8%(23/24) and 100%(56/56), respectively. Conclusion Ovarian cancer can be quickly and correctly diagnosed by this method with high sensitivity and specificity. That will be widely used in clinical application
