Objective To study the mechanism of the Compound Qinbai Granule (Granules composed of Scutellaria root and Phellodendron bark) in the treatment of radioactive dermatitis in rats.Methods The rat models of radioactive dermatitis were established and randomized into three groups:Compound Qinbai Granule group (experimental group),dexamethasone ointment group (traditional group),and normal saline group (control group).The wound was treated with Compound Qinbai Granule spray,dexamethasone ointment external application,and normal saline spray respectively.By immunohistochemical staining and image analysis,the growth of granulation tissue in the wound area wound healing rate,and the expression of basic fibroblast growth factor (bFGF) in the wound tissues were determined on the second,sixth,tenth,eighteenth,and twenty-fourth day after injury.Results The average number of granulation tissue and wound healing rate in the experimental group on the sixth,tenth,eighteenth,and twenty-fourth day were all higher than those in the traditional group and control group with a significant difference (P

As important regulators of apoptosis,bcl-2-family proteins regulate all major types of cell death,including apoptosis,necrosis,and autophagy.It's known that impaired apoptosis is a critical step in tumor development.Overexpression of antiapoptotic proteins of bcl-2 family is associated with the development and prognoses of malignant lymphoproliferative disorders.

Hypoxia could not only induce tumor chemoradiotherapeutic resistance, but also cause strong invasiveness which make tumor inclined to recurrence and metastasis. With regard to the detection of oxygenation condition in tumor tissue, there are many methods, but each has its advantages and disadvantages. Accurate monitoring of tumor oxygenation state plays an important role in therapeutic schedule formulation and implementation which would improve curative effect of tumor.

OBJECTIVETo compare the effect of three cannulated screws and dynamic hip screw (DHS) combined with antirotation screw in treating patients with comminuted fractures of femoral neck.

METHODSFrom January 2008 to December 2012,67 patients with comminuted fractures of femoral neck were treated with three cannulated screws or DHS combined with antirotation screw. Among them, 36 patients were treated with DHS combined with antirotation screw including 24 males and 12 females with an average of 43.7 years old ranging from 22 to 58 years old; 31 patients were treated with three cannulated screws including 22 males and 9 females with an average of 43.0 years old ranging from 24 to 56 years old. The incision size, operation time, blood loss, blood transfusion rate, postoperative hospital stay, walking time, weight-bearing time, union time, incidence of complication were recorded and compared between two groups, and functional outcomes were evaluated by Harris scoring.

RESULTSAll incision healed at stage I. The differences in operation time, blood loss, blood transfusion rate and postoperative hospital stay between two groups were not significant (P > 0.05). Incision size of DHS group (5.00 ± 0.86) cm was larger than that of cannulated screw group (3.30 ± 0.57) cm (P < 0.01). All patients were followed up more than one year, and the follow-up time showed no significant difference between two groups (P > 0.05). Walking time of DHS group (19.0 ± 3.5) d was less than that of cannulated screw group (37.0 ± 6.3) d (P < 0.01. Partial and full weight-bearing time of DHS group (23.0 ± 7.0) d and (138.0 ± 13.0) d was less than that of cannulated screw group (38.0 ± 5.7) d and (164.0 ± 12.0) d (P < 0.01). Union time of DHS group (151 ± 11) d was less than that of cannulated screw group (162 ± 11) d (P < 0.01). Harris hip score of DHS group (91.0 ± 5.7) was higher than that of cannulated screw group (85.0 ± 12.0) (P < 0.01). No significant differences were found in the incidence of postoperative complications between two groups (P > 0.05).

CONCLUSIONThe DHS combined with antirotation screw is superior to three cannulated screws for treatment of comminuted fractures of femoral neck due to earlier weight-bearing, faster fracture healing and better hip function

Objective To explore the role of sCD44v6 in the diagnosis of colorectum cancer. Methods ELISA was used to detect the concentration of sCD44v6 of 81 patients after or before surgery.Results The level of sCD44v6 in the group of colorectum cancer was 200.5?31.1 ng/ml, which was higher than that of normal controls (45.6?9.5ng/ml) and that of patients with coloritis (48.3?7.6ng/ml). The concentration of sCD44v6 in the group of colorectum cancer with metastasis(280.1?26.9ng/ml) was higher than that of the group without metastasis(160.9?34.4ng/ml). The level of sCD44v6 was related to tumor burden.Conclusions The level of sCD44v6 is closely related to colorectal cancer and its metastasis. It would be useful in the diagnosis, prognosis, and forcasting of metastasis.

[Objective] The disease distribution of in-patients in different age groups from 1993 to 2002 in respiratory disease department of Guangdong Provincial Hospital of Traditional Chinese Medicine (TCM) was analyzed to provide evidence for clinical treatment. [ Methods ] A retrospective research was adopted. Fourteen categories of diseases and 3 age groups were classified according to the case history recorded from 1993 to 2002 in respiratory disease department of Guangdong Provincial Hospital of TCM. Reasons for hospitalization of the in-patients in different age groups during 10 years were analyzed by descriptive analysis and Vilfredo Pareto analysis. [Results] The principal and secondary reasons for hospitalization were respiratory tract infection, pulmonary tuberculosis and pneumothorax in the young age group while in the old age group, they were chronic bronchitis, pulmonary emphysema, chronic pulmonary heart disease and lung cancer. [Conclusion] The focus of daily medical treatment in the department of respiratory disease should vary with the age groups and disease categories, and the control of infectious diseases should be generally strengthened.

Insulins maintain blood glucose homeostasis in the body by stimulating glucose uptake into muscle and adipose tissues through glucose transporter type 4 (GLUT4)translocation. Recent studies have showed that Rab proteins,as a key regulatory factor for the translocation of GLUT4 to the cell membrane,participate in the formation,translocation and fusion of GLUT4 vesicles. This paper describes several types Rab proteins and the Rab GTPase activating protein,protein kinase B substrate of 160 kU(AS160)in terms of regulatory mechanisms for GLUT4 translocation. Studies on the translocation mechanism by which GLUT4 is regulated by Rabs aim to explain the mechanism of insulin resistance in type 2 diabetes,and provide a new approach to diabetes.

OBJECTIVE: To study the relationship between negative life events and quality of life of tinnitus patients, and explore the role of negative life events in psychological counseling and rehabilitation of tinnitus. METHOD: Sixty-one cases of tinnitus patients and 61 normal controls were tested with tinnitus handicap inventory and life event scale, scores were compared and the associated analysis was made. RESULT: Stimulating quantity of negative life events in the tinnitus group, compared with the control group was statistically different (Z = -2.56. P < 0.05). The incidence of negative life events in the tinnitus group compared with the control group was no statistically different (chi2 = 0.05, P > 0.05). The incidence of abnormal scores of negative life events compared with the control group was statistically different (chi2 = 16.68, P < 0.01). Positive correlation in tinnitus group was found between scores of negative life events and scores of tinnitus handicap inventory (r = 0.41, P < 0.01). The higher the score of negative life events, the lower the quality of life with tinnitus patients. CONCLUSION Severity of negative life events and tinnitus is closely related, and negative life events can reduce the quality of tinnitus patients life. We should pay more attention to negative life events in psychological counseling with tinnitus patients. The intervention in negative life events can improve the quality of life. providing the targeted and individualized theory basis for tinnitus psychological counseling and rehabilitation.
