Objective To study the effects of different factors influencing the quality of life of elderly esophageal cancer patients who returned to the community after surgery.Methods A total of 216 elderly esophageal cancer patients with complete clinical data who had returned to the community after surgery were followed up by questionnaires,including the European Organization for Research and Treatment of Cancer Quality of Life rating (EORTC QLQ-C30) and esophageal cancer supplementary (QLQ-OES18) scales.Results The overall quality of life score of the patients was (35.2±22.1),which was lower than that in the Norwegian norm data.Scores for cognitive function,constipation,diarrhea,shortness of breath and loss of appetite were similar to those in the norm data.Scores for physical function,emotional function,role function and were lower than those in the norm data,while scores for pain,fatigue,nausea and vomiting,sleeplessness and were higher than those in the norm data.The overall quality of life score was higher in male patients than in female patients (F =5.12,P=0.029),in patients with spouses than in those without spouses (F=5.61,P=0.016),and in patients without complications than in those with complications (F=5.48,P=0.002).The overall quality of life was higher with longer survival times after surgery (F=3.68,P=0.003).No significant difference in the overall quality of life score was found between different age-groups (F=4.23,P=0.212).Conclusions The overall postoperative life quality is poor in community elderly patients with esophageal carcinoma.Gender,marital status,postoperative survival time,and complications are among the factors influencing postoperative quality of life of community elderly patients with esophageal carcinoma.

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.

Genistein, as one kind of phytoestrogens, can stimu-late osteoblastic proliferation, differention and mineralization, and can also inhibit bone resorption activity of osteoclast. The effect of genistein on bone metabolism lies in various molecular mechanisms. This paper reviews the research progress of the an-ti-osteoporotic action of genistein and its mechanism, which may provide a basis for the research and development of new agents to treat osteoporosis.

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.

Objective To investigate the values of CD21 and CD43 proteins in the differential diagnosis of mucosa-associated marginal zone B-cell lymphoma (MALToma) from benign lymphadenosis. Methods The expression of CD21 and CD43 proteins in the tissues of 25 MALToma (case group) and 25 benign lymphadenosis (control group) was detected by immunohistochemistry. Results Abnormal CD21+follicular dendritic cells (FDC) meshes were found in all patients of case group. Most of the FDC meshes were sparse and broken, and a few were enlarged or fused into pieces. Intact CD21+FDC meshes were all found, and abnormal FDC meshes were not found in control group. The positive rate of abnormal FDC meshes in case group was significantly increased compared with that in control group (χ2 = 46.080, P= 0.000). The expression rate of CD43+in CD20+cells was 24 % (6/25) in case group, but it was negative in control group (χ2=4.375, P=0.030). Conclusions Abnormal CD21+FDC meshes and CD43+expression in CD20+cells are useful in the differential diagnosis between MALToma and benign lymphadenosis. The abnormal FDC meshes of MALToma are enlarged or fused in the minority of cases.
