Objective If IL-2 and IFN-? are united,perhaps we may see a more significant antitumor effect.A fusion gene of IL-2 and IFN-? was designed and constructed by DNA engineering.Methods CEA promotor、IL-2cDNA and IFN-?cDNA were obtained by PCR and RT-PCR.SDS-PAGE was used to examine the results;pcDNA-IL-2、pcDNA-IFN-?、pCEA-IL-2/ IFN-?、pEGFP-IL-2/ IFN-? were transfected to CEA high expression cell line(Lovo)by use of liposome.The fusion protein expression was examined by fluorescence microscope and Western blotting.Results IL-2/ IFN-? fusion gene can be expressed in tumor cells.Its expression is more obvious in CEA high expressed cells(Lovo),and can be located in cell plasma.Conclusion The fusion gene can be expressed in plasma of CEA high expressed cell lines.It may have a new anti-tumor effects.

Objective:To investigate the clinical efficacy of loratadine combined with compositus mentholi cream in the treatment of infantile with external ear eczema and evaluate the safety .Methods:Totally 96 cases of infantile with external ear eczema were ran-domly divided into the observation group (n=48) and the control group (n=48) according to a random number table .Both groups were given the conventional treatment .The control group was treated with topical compositus mentholi cream , while the observation group was treated with loratadine additionally .Both groups were treated for 10 d.The clinical efficacy , the level changes of interleukin-4 (IL-4), interferon-γ(IFN-γ) and immunoglobulin-E (IgE) before and after the treatment, the incidence of adverse reactions during the treatment and the relapse after 6-month follow-up were compared between the groups .Results:The total effective rate of the obser-vation group (95.83%) was significantly higher than that of the control group (79.17%, P<0.05); the levels of IL-4, IFN-γand IgE in both groups were significantly decreased after the treatment (P<0.05), and those in the observation group were significantly lower than those in the control group (P<0.05);there was no significant difference in the incidence of adverse reactions between the groups (P<0.05); the recurrence rate in the observation group (8.33%) was significantly lower than that in the control group (22.92%, P<0.05).Conclusion:The clinical efficacy of loratadine combined with compositus mentholi cream in the treatment of infantile with external ear eczema is reliable with promising safety .

The WeChat service provided at present in 14 hospitals directly under the Yunnan Health and Family Planning Commission was surveyed with suggestions proposed for providing active Wechat service in hospitals in order to alleviate the difficulty to see a doctor and the tense relationship between doctors and patients.

Reading therapy in hospital libraries, academic libraries and public libraries was described in terms of its theoretical study and practical study,and its significance in hospital library was elaborated by comparative analysis.

Orthodontic tooth movement (OTM) is a very complicate mechano-biological procedure which is accomplished by the remodeling of periodontal tissues via orthodontic force.As the connective tissue between alveolar bone and cementum,periodontal ligament plays a vital role in the response and conduction of orthodontic force.The susceptible response of periodontal ligament to orthodontic force during OTM is a critical factor on inducing and modulating periodontal tissue restitution.This article reviews the concrete role of periodontal ligament and its mechano-biological behavior during OTM,discusses its mechanical response and biological mechanism respectively on histological,cellular and moleucular levels.

Since cancer-related pain is the worldwide problem,intrathecal drug delivery system (IDD)has been an effective pain management option for patients with chronic and cancer pain.Compared with the other ways,such as oral or intravenous infusion,the delivery of drugs into the intrathecal space provides superior analgesia with lower doses of analgesics to minimize side effects while significantly improve quality of life.Recently,besides traditional opioid (especially mainly morphine) for intrathecal,clinical experts have also found some other drugs could be used for IDD to control the cancer-related pain,and have observed their effect and related adverses.This article aims to provide a general overview of the development trend in this field.

Objective:To develop an HPLC method for the assay of the content of triptolide in triptolide gel. Methods:The content of triptolide was measured by HPLC on Diamonsil C18 column(250mm?4.6mm i.d,5?m)using methanol-water(46∶54,v/v)as mobile phase,at a flow rate of 1.0ml/min. The UV detection was set at 220nm. Results:The calibration curve was proved to be linear in the range of 10.24~51.20?g/ml with a regression coeficient of 0.999 7. The average recovery of the method was 98.3%;RSD was 0.23%(n=5). Conclusion:This method is found to be rapid and accurate for the measurement of triptolide in triptolide gel.

Objective To discuss the correlation between the expressions of high mobility group protein box 1(HMGB1),VEGF-C/D and lymph node metastasis in colon cancer.Methods Forty-five colon cancer samples were stained by immunohistochemical method for VEGF-C/D,HMGB1.The correlations of VEGF-C/D,HMGB1 expressions and lymph node metastasis were analyzed statistically.Results Positive HMGB1 expression was in 33 specimens,lymph node metastasis was in 27 specimens with 23 specimens of positive HMGB1 and non-lymph node metastasis was in 18 specimens with 10 specimens of positive HMGB1.Positive VEGF-C expression was in 27 specimens with 20 in lymph node metastasis.The expression of HMGB1 was consistent with VEGF-C expression,and HMGB1 and VEGF-C expressions were closely correlated with lymph node metastasis,but not with age,sex,cellular differentiation.Conclusion HMGB1 and VEGF-C expression may become predictor to the prognosis of colon cancer patients.

Objective To discuss the clinical effect on treating hysteromyoma with compound acetic acid gossypol tablets.Methods 50 patients who are diagnosed with hysteromyoma take compound acetic acid gossypol tablets 20mg after supper every day for 3 months. Then Monitor the size of uteruses and tumors of the patients,hemoglobinuria routine、liver function、blood sugar、blood ester、follicle stimu- lating hormone、luteinizing hormone、lactation hormone、progestogen hormone、androsterone hormone using B-ultrasound waves before and after treatment.Results patients will have amenorrhea during treatment and the symptom will disappear.The tumor will dwindle in size by 54.66%(P＜0.01)on average.The Hysteromyoma will dwindle by 50.66%(P＜0.05)on average.Also hemoglobin,Hb returns to nom- al.As a result,the blood sugar and lactation harmone reduce a lot than that before treatment.And other monitoring quality doesnt change obviously.Conclusions There is of great effect using compound acetic acid gossypol tablets to treat hysteromyoma and it has no side effect.It is an available conservative treatment.

Objective: To establish a model of rat osteosarcoma in nude mice and to study its biological characteristics.Methods: Intact tumor pieces were inoculated into the right tibia of nude mice.The nude mice were killed at different time and the growth of tumor and metastasis were observed.Result: The tumor growth rate was 100%.From the first week to the second week after implantation it grew into outer tissue from tibia,and widely invaded Soft tissue on the third week.Pulmonary metastasis took place from the fourth week to the fifth week,and the nude mice died of cachexia and respiratory failure resulting from the widely whole pulmonary metastasis on the sixth week or so.Conclusion: The tumor growth rate is high.The model simulates the clinical process of human osteosarcoma,and could be a satisfactory model for studying osteosarcoma.
