As one subclass of forkhead proteins, the forkhead box O ( FoxO) transcription factors take part in a series of bio-logical processes including cellular apoptosis, damaged DNA re-pair and cleavage of reactive oxygen species(ROS). Increasing evidence highlights that oxidative stress elicited by FoxOs con-tributes to imbalance of redox status in cells related to bone me-tabolism, resulting in development of the pathogenesis of osteo-porosis. This article reviews the relationship of FoxOs and osteo-porosis, which may be beneficial for the research of pathological mechanism and therapeutic strategy of osteoporosis.

The clinical data of 459 patients,who were first diagnosed as HIV/HBV co-infection from January 2007 to December 2013,were retrospectively analyzed.Among all patients,there were 89 cases with CD4 ＜ 50/μl,134 cases with CD4 50-200/μl and 236 cases with CD4 ＞ 200/μl,when HIV infection was diagnosed.In these three groups with different CD4 levels,the HBV DNA positive rates were 49.3％ (37/75),50.5％ (54/107) and 33.7％ (66/196);the HBV viral load were (6.37 ± 1.71) log10 copies/ml,(5.82 ± 1.86) log10 copies/ml and (4.36 ± 1.64) log10 copies/ml;the rates of abnormal liver function were 29.2％ (26/89),29.1％ (39/134) and 10.6％ (25/236);the occurrence rates of end-stage-liver-diseases were 16.9％ (15/89),14.9％ (20/134) and 5.1％ (12/236);the mortality rates were 10.1％ (9/89),9.7％ (13/134) and 3.8％ (9/236),respectively.The HBV DNA positive rates,HBV viral load,the rates of abnormal liver function,the occurrence rates of end-stage-liver-diseases and the mortality rates in CD4 ＞ 200/μl group were lower than that in CD4 ＜ 50/μl group and 50-200/μl group.The results suggest that for HIV and HBV co-infection patients,HBV replication level and prognosis of liver diseases are associated with CD4 + T lymphocyte count.

BACKGROUND:Low concentration of nicotine promotes the angiogenesis and facilitates the healing of skin wounds. However, the role of low concentration of nicotine on the repair of maxil ofacial soft tissue trauma especial y oral mucosa stil remains unclear
OBJECTIVE:To evaluate the effect of low concentration of nicotine on mucosa defect repair of rat hard palate.
METHODS:A circular soft tissue defect at 3 mm diameter was produced in the centre of hard palate of 65 Wistar rats. After the operation, animals were randomly divided into low concentration of nicotine with gel group, gel group and control group. Rats were sacrificed at 3, 7, 10 and 14 days post-surgery. The wound healing was detected with hematoxylin-eosin staining and the difference of wound healing in different groups was compared with gross observation and image measurement.
RESULTS AND CONCLUSION:There was no significant difference in the wound healing in different groups on day 3 post-surgery. On days 7 and 10, the group of low concentrations of nicotine with gel was faster than gel group and control group (P<0.05);the wounds were completely healed on day 14, with no significant difference among the groups. Low concentrations of nicotine may promote the mucosa defects repair of rat hard palate.

Objective To explore the proportion of different types of stones in patients with kidney stones in Xinjiang, and to analyze the relationship between stone composition and urine physicochemical properties and protein composition.Methods Through a case-control study, 355 patients with kidney stones who were hospitalized in the Xinjiang Uygur Autonomous Region People′s Hospital from March to November 2010 were enrolled in the same period, and non-urinary tract diseases were hospitalized and excluded from other diseases or complications of the 30 cases of renal impairment in the control group.The composition of the stones was analyzed.The main components of the stones were divided into oxalate group, carbonic acid group, uric acid group and phosphate group.The physicochemical properties and protein composition of 24 h urine were analyzed by ion selective electrode method, enzymatic and immunoturbidimetric assay.The difference between the two samples was analyzed by t test, and the differences between the two groups were analyzed by F-test and LSD-t test.Results Compared with the control group(30 cases), urine pH(5.33±0.32) was significantly lower in the oxalate group (244 cases), 24 h urinary calcium and 24 h uric acid[(7.68±0.35) mmol, (3.48±0.23)mmol (pH=5.874,P<0.05)].The urine pH (6.98±0.77) was increased in the phosphate group (23 cases), and the 24 h urinary magnesium (3.02±0.29) mmol was significantly lower than in the control group (10.56±0.63) mmol, and the level of 24 h urinary calcium (7.96±0.569) mmol increased (t>9.436, P<0.05).There were 23 patients with calcineuria (P<0.05).The urine pH level in the uric acid group (61 cases) was as low as (4.97±0.48), and 49 patients were accompanied by excessive acidification (80.3%) and 24 h uric acid (4.14±0.37) mmol (t=11.459,P<0.05).And the urine pH (6.86±0.68) was higher in the phosphate group (n=23) (t=6.876,P<0.05).In addition, urinary Cystatin C (0.653±0.148)mg/L, urinary α1-microglobulin (1.53±0.56)mg/dl and urinary β2-microglobulin (0.585±0.088)mg/L in the oxalate group (t>8.442,P<0.05).Conclusion There may be a correlation between renal stone composition with urine metabolic changes.
