Daxx is found in the nucleus where it localizes to PML oncogenic domains (PODs). Its multiple domains can interact proteins involved in transcriptional regulation and apoptotic signal transduction. In addition, Daxx is associated with viral infection、tumorigenesis and embryonic development.

Objective To investigate the effects of long-term replacement therapy of estrogen or compound estrogen on the deposition of beta-amyloid protein (A?) in ovariectomy (OVX) rat hippocampal formation. Methods Fifty seven-month-old female Sprague-Dawley rats were randomly divided into five groups: normal control, SHAM, OVX, OVX plus 17beta-estradiol (OVX/ERT), and OVX plus compound nylestriol tablet (OVX/NL). The ovariectomy was performed in OVX, OVX/NL and OVX/ERT rats and drugs were administered orally in OVX/NL and OVX/ERT rats for 35 weeks after the ovariectomy. Then the rats in all groups were sacrificed. Immunohisto-chemistry of A?, cell counting and imaging system were used to determine the change of A? deposition levels in OVX rat hippocampal formation. Results The numbers and optical density of A?-positive neurons of all hippocampal subregions and dentate gyrus in OVX rats were markedly higher than those of normal control, SHAM,OVX/NL, and OVX/ERT rats( P

Objective To evaluate the preoperative liver function and prognosis of laparoscopic cholecystectomy (LC) in patients with cirrhosis,using the Child-Turcotte-Pugh classification and the model for end-stage liver disease(MELD) score.Methods From January 2009 to June 2013,973 patients who were admitted to the Department of General Surgery of our hospital and the HuiZhou Municipal Central Hosptial were studied.Of the 373 patients with cirrhosis,38 patients were excluded because of Child C,MELD ＞ 30,or laparotomy.The remaining 335 patients who received laparoscopic cholecystectomy were randomly divided into two groups The Child grade and MELD score were retrospectively analyzed.Results There was no significant difference in intraoperative hemorrhage between the Child A group [(106 ± 11) ml] and the Child B group [(109 ± 11) ml] (P ＞ 0.05).The R ＜ 14 scores in the MELD group [(58 ± 15) ml] was significantly lower than that in the R≥ 14 group [(120 ± 28) ml] (P ＜ 0.01).There was no significant difference in postoperative complications between the Child group A (10 cases,12％) and the Child group B (17 cases,21％) (P ＞0.05).There was a significantly lower incidence in the R ＜ 14 scores in the MELD group (10 cases,12％) than the R ≥ 14 group (27 cases,33％) (P ＜ 0.05).There was also no significant difference in the hospital stay between the Child A group (9 ± 1) and the Child B group (10 ± 2)(P ＞0.05) ; the R ＜ 14 score of the MELD group (7 ± 1) was significantly less than that of the R≥ 14 group (11 ±2) (P ＜0.01).There was no significant difference in the cost of hospitalization between the Child A group (1.337 ± 0.063) and the Child B group (1.359 ± 0.089) (P ＞ 0.05) ; the R ＜ 14 group (MELD score 1.108 ± 0.123) was significantly less than that of the R ≥ 14 group (1.568-± 0.117)(P ＜ 0.01).Conclusion Compared with the Child-Turcotte-Pugh classification,the MELD score was more scientific,objective and accurate in judging the preoperative liver function.It helped to predict the amount of intraoperative hemorrhage and postoperative morbidity,reduced hospital stay and hospitalization expenses.Therefore,the MELD scoring system more objectively guided the treatment of patients with cholecystitis with cirrhosis.

Objectives To investigate the role of laminin (LM) and fibronectin (FN) in the growth cycle of human hair follicles. Methods The expression of LM and FN was detected by streptavidin-peroxidase (SP) staining. Results In the anagen phase, LM was expressed in dermal papilla, basement membrane and outer root sheath; FN was expressed in dermal papilla, basement membrane and connective tissue sheath. In the catagen phase, LM showed a lower expression in the dermal papilla and a linear expression in the basement membrane; the expression of FN in the dermal papilla and basement membrane was less intense than that in anagen phase, but was still positive. In the telogen phase, LM was only expressed in the basement membrane while FN was negative. Conclusion The difference between LM and FN expression in hair growth cycle indicates that LM and FN may play important roles in the regulation of human hair follicle growth cycl.

Objective To study the efficacy and safety of Solifenacin on female overactive bladder (OAB) symptoms secondary to uncomplicated lower urinary tract infection. Methods Seventy-three adult female patients who had clinically diagnosed as OAB symptoms secondary to uncomplicated lower urinary tract infection were randomly divided into treatment group (41 cases) and control group (32 cases). Treatment group received Solifenacin , 5 mg orally qd , as well as OAB behavioral therapy , but control group was given only OAB behavioral therapy. The overactive bladder syndrome score (OABSS) was evaluated before and after antibiotic treatment in all the patients , and the treatment or observation time lasted four weeks after the antibiotic treatment were deactivated. Then OABSS scoring and the cure rate between two groups were compared. Results OABSS score of treatment group decreased significantly after receiving Solifenacin treatment one week , and the cure rate reached 56.10%, and two weeks later, the cure rate reached 92.68%. OABSS score of control group had no significant change one week after treatment and the cure rate was only 6.25%, but at the fourth week OABSS had decreased significantly and the cure rate reached 37.50%, which was still significantly lower than that of treatment group. There were no drug adverse events during treatment in both groups. Conclusions There is obvious clinical effect of solifenacin on female OAB symptoms secondary to uncomplicated lower urinary tract infection, which is safe and could significantly shorten the course of treatment.

Objective To investigate the possible mechanism of gemcitabine resistance in pancreatic cancer chemotherapy. Methods Recent literatures about the genes and signal pathways those play key roles in mediating gemcitabine chemotherapy resistance of pancreatic cancer were collected and reviewed.Results Oncogenes like c-Src and bcl-X-L, inflammation pathway of NF-?B, cytokines like IL-1? and NO are closely related with the chemoresistance; the relationship between multiple drug resistance relevant genes like MDR1/P-gP and the resistance to gemcitabine remains to be clarified. Conclusion Genes and pathways like c-Src, bcl-X-L, NF-?B, etc. might become new targets to increase the chemotherapeutic sensitivity of pancreatic cancer, however, the mechanism of pancreatic cancer chemotherapy resistance still needs further to be studied.
