Objective To investigate the results difference of the indirect immunofluorescence (IIF) and immunoblotting (LIA) for detecting ant-inuclear antibodies (ANA) and clinical value .Methods One hundred and forty-six ANA detection specimens of IIF negative and LIA positive were collected and performed the detection of HBV antibodies and anti-HCV antibodies .Results (1) In 146 specimens of IIF (-)LIA (+ ) ,the positive specimen numbers of single anti-Ro52 antibody ,anti-SSA antibody and anti-AMA-M2 antibody were 69 cases ,42 cases and 15 cases respectively ,which of anti-RNP antibody ,anti-PCNA antibody and PM-Scl antibody were 3 cases ,5 cases and 2 cases respectively ,the combined 2-item positive was in 8 cases .(2)Among positive specimens of single anti-Ro52 antibody ,HBsAg(+ ) ,anti-HBe(+ ) ,anti-HBc(+ ) model and HBsAg(+ ) ,HBeAg(+ ) ,HBcAb(+ ) model of hepatitis B ,and hepatitis C were 51 cases ,4 cases and 7 cases respectively ,7 cases were non-hepatitis patients .(3) Among positive specimens of single ant-SSA antibody ,6 cases were hepatitis B patients and 36 cases were the patients with non-hepatitis B .Conclu-sion Anti-Ro52 antibody and anti-SSA antibody are easier to be missed by the IIF detection .Anti-Ro52 antibody positive has a cer-tain relation with small three positive of hepatitis B .

Neurodegenerative diseases are chronic lesions caused by neuronal degeneration and secondary demyelination.Recent studies have shown that a DNA/RNA binding protein named fused in sarcoma/translocated in liposarcoma protein (FUS/TLS) is associated with neurodegenerative diseases,such as amyotrophic lateral sclerosis (ALS),frontotemporal dementia (FTD) and polyglutamine diseases.Mutations or dysfunction in FUS/TLS are responsible for the abnormal processes in the related gene transcription,RNA processing,transportation and translation and are highly correlated with the development of neurodegenerative disease.Discovery and the research of FUS/TLS not only contribute to the understanding of neurodegenerative disease at RNA level,but also provide a new way for the prevention and treatment of neurodegenerative diseases.

ObjectiveTo explore the efficacy of the technique of reticular basket through cystic duct stone removal during laparoscopic common bile duct exploration.MethodsFrom January 2008 to February 2011,185 patients received laparoscopic bile duct exploration in our hospital.These patients underwent intraoperative cholangiography (IOC) through the cystic duct with a reticular basket.With the help of a choledochoscope,a reticular basket was used to take out stones for patients who were shadow-positive.Re-cholangiography was then performed to ascertain that no stone was retained in the biliary tract.ResultsOf the 185 patients,60 were found to be positive on IOC.Stones were successfully removed by using a reticular basket through the cystic duct in 45 patients,and through the cystic duct and common bile duct after a micro-incision was made under choledochoscopic assistance in 10 patients.After laparoscopic common bile duct exploration re-cholangiography found no residual stones in these patients. In 5 patients,stones were removed after conversion to open surgery. Conclusions During laparoscopic common bile duct exploration,using reticular baskets via the cystic duct for intraoperative cholangiography (IOC) and removing stones is of great value.

Objective To explore the interventional effect of recombinant human brain natri-uretic peptide(rhBNP)on the patients with sepsis induced myocardial dysfunction by comparing N-terminal pro-B-type natriuretic peptide(Nt-proBNP),troponin and left ventricular ejection fraction (LVEF).Methods Forty septic patients were admitted into department of critical care medicine from February 2013 to May 201 5.They were randomly divided into control group and rhBNP group,with 20 patients in each group.Both groups received early goal directed therapy(EGDT),and rhBNP group re-ceived additional therapy of rhBNP 1.5 μg/kg bolus,and then 0.075 μg·kg-1 ·min-1 for 48 h.Con-trol group received saline in the same way.Vasoactive agents were used to maintain blood pressure. Concentration of plasma Nt-proBNP and troponin were determined at baseline,on days 1,3,and 7 day by point of care (POCT ).LVEF was also detected by transthoracic echocardiography. Results Concentrations of plasma Nt-proBNP and troponin in rhBNP group were lower than control group on days 1 and 3 (P <0.05).On day 3,levels of Nt-proBNP and troponin in both groups were higher than the days 1 and 7 (P <0.01).LVEF in the rhBNP group was higer than control group on days 3 and 7 (P <0.05 or P <0.01);On day 3,LVEF in both groups was significantly lower than the pre-therapy and day 7 (P < 0.05 or P < 0.01 ).Conclusion rhBNP can improve sepsis induced myocardial dysfunction by decreasing the Nt-proBNP and troponin levels with increased left ventricular ejection fraction.

BACKGROUND: Skinfold thickness instrument was used to analyze the distribution and development of subcutaneous fat. This method is simple, economic, and widely used. OBJECTIVE: To investigate the body fat development and age changes in female adults from Maonan nationality in Guangxi province. DESIGN, TIME AND SETTING: The cluster sampling investigation was performed at the Department of Anatomy, Basic College, Youjiang Medical College for Nationalities from September to October 2006. PARTICIPANTS: Using random sampling method, 533 healthy adult females of Maonan nationality and aged 25-75 years were selected from Huanjiang county of Guangxi province. They all live in Huanjiang count for over 10 years and their parents were also Maonan nationality. Taking five years were served as a group, totally 10 groups. METHODS: The indexes were measured and calculated by professionals according to Handbook of Human Measure. The equipment was modified skinfold thickness instrument. The database was set up in computer. MAIN OUTCOME MEASURES: Skinfold thickness of triceps brachii, anterior superior iliac spine, inferior angle of scapula and gastrocnemius. Four indexes were compared with other groups in China. RESULTS: The torso skinfold was thicker than limb ones. Skinfold thickness decreased with age after it came to the maximum. Compared with other minornationalities, the skinfold of Maonan adult females in Huanjiang of Guangxi province was thinner than Daur and Uzbek, but thicker than Bouyei nationality. CONCLUSION: The skinfold thickness of Chinese Maonan nationality in Guangxi province has a wavy change. It is thicker than Bouyei nationality and thinner than those in Dong nationality and Daur nationality and Uzbek nationality.
