[Abstract ] Objective Nephroblastoma is one of the solid malignancies with fair prognosis in children .The lungs, liver, and bones are the common organs for distant metastasis of the tumor and important factors influencing the therapeutic effects as well .This study was to investigate the clinical characteristics and prognosis of nephroblastoma with distant metastasis in children . Methods We retrospectively analyzed the clinical characteristics , pathological features , and prognosis of 9 cases of nephroblastoma with distant metastasis treated in Nanjing Children Hospital from September 2011 to May 2015 . Results The patients presented with abdominal masses, distention and pain at preliminary diagnosis and confirmed with nephroblastoma , with pulmonary metastasis in 7 cases, liver metastasis in 1, and lung and liver metastases in the other .All were treated by surgery, radiotherapy, and chemotherapy and followed up for a median time of 34 months.By the end of the follow-up, 1 patient died of recurrence , 1 was undergoing chemotherapy , and the other 7 were being recovered, including complete disappearance of lung metastasis in 4, obvious reduction or calcification of lung metastasis in 2, evident disappearance of liver metastasis in 1, but relapse in none. Conclusion Lung and liver are common sites of nephroblastoma metastasis in children .As for the treatment of the disease , relatively good results can be achieved by radiotherapy , chemotherapy , and reoperation .

Recently, along with the harmful factors in air in-creasing, the incidence of respiratory system diseases has been gradually rising. Therefore, more studies are focused on impro-ving the prevention and treatment on respiratory system diseases. Current researches have shown that microRNAs ( miRNA ) con-tribute to the prevention and treatment on respiratory system dis-eases, including virus infectious respiratory disease, pulmonary fibrosis, asthma, COPD, pulmonary tuberculosis and lung canc-er. The up-regulation and down-regulation of microRNAs could effectively regulate the biological process of these diseases. The review analyzes the recent years′study results of respiratory sys-tem diseases and microRNAs in depth, and discuss the role of microRNA in the treatment and prevention of respiratory disea-ses. Moreover, in this review we can provide new knowledge a-bout respiratory diseases and development of more potent drug targets for the treatment and prevention of respiratory diseases.

Objective To discuss the influence of parturition balloon on the labor course of primi-paras. Methods We divided 160 primiparas into the observation group and the control group with 80 cases in each group.We gave the observation group parturition balloon intervention with the help of midwife. Nursing measures in the control group were the same as those of the observation group except for the appli-cation of parturition balloon. We observed and compared the psychological status,pain;labor course,dehvery manner and postpartum hemorrhage between the two groups. Results The patients in the observation group got alleviation of psychological condition and pain.The rate of caesarean operation rate,postpartum hemorrhage and time cost of labor course were shortened,which were statistically different from those of the control group(P < 0.01 ). Conclusions Nursing intervention with parturition balloon for primiparas could alleviate pain of the patients, shorten time cost of labor course,improve rate of natural parturition and de-crease caesarean operation rate.It is a service model for delivery worthy of application.

OBJECTIVE:To study the quality standards for Shenchang injection.METHODS:TLC was applied to identify the properties of Borneol and volatile oil of Rhizoma Acori Tatarinowii in the formula.HPLC was adopted to determine the content of ?-asarone in Shenchang injection.RESULTS:?-asarone showed good linear relationship in the range of 0.632 3～ 1.264 6? g.The average recovery of ammonium ?-asarone was 99.92%(RSD=0.91%).CONCLUSION:The standard can be used for the quality control of Shenchang injection.

Objective To study the percentages of polymorphonuclear leukocytes (PMN), mononuclear cells (MNC) and fibroblastic cells (FBC) in different post-traumatic intervals after skeletal muscle me-chanical injury in rats. Methods The rat model of skeletal muscle mechanical injury was established. The rats were divided into injured groups (6 h, 12 h, 1 d, 3 d, 7 d, 10 d and 14 d after injury ) and con-trol group. The percentages of PMN, MNC and FBC in different post-traumatic intervals after skeletal muscle mechanical injury were assessed with HE staining and image analysis. Results At post-injury 6-12 h, the percentages of PMN and MNC infiltration appeared in injured sites and that of PMN reached peak. At 1 d, the percentage of MNC infiltration appeared and reached peak, while that of PMN de-creased. At 3-7 d, the percentage of FBC gradually increased, while that of PMN and MNC decreased. At 10-14 d, the percentage of FBC reached peak. Conclusion The percentages of PMN, MNC and FBC in injured zones showed time-dependent changes, which might be used as reference index for determination of age of skeletal muscle injury.

AIM:To establish the fingerprint chromatogram of amino acids compounds of Xiasangju Granules(Spica Prunellae,Flos Chrysanthemi indici,Folium mori.).METHODS:To apply 6-aminoqtiinoly-N-hydroxysuccinimdyl carbamate(AQC) pre-column derivatization HPLC method.Separation was performed on SYMMETRY C_(18)(150 mm?(4.6) mm,5 ?m) analytical column with mobile phase consisting of acetate(pH=(5.05)) and 60% acetonitrile with gradient elution with the flow rate(1.0) mL/min and the column temperature at 37 ℃.The Fluorescence wavelength used for detection was set at 250 nm(Excitation wavelength) and 395 nm(Emission wavelength) and the analysis time was 50 min.RESULTS:12 co-peaks on the HPLC fingerprints of Xiasangju Granules were indicated.The similarities were determined by the coefficients of cosine and correlation.The results of similarity analysis were(0.95)-(1.00).CONCLUSION:Perfect fingerprints were obtained which can be used for the quality control of Xiasangju Granules.

Objective To establish the fingerprint chromatogram of Buzhong Yiqi Decoction(BYD) by multiple wavelength method,and to analyze the substance of formulas as a whole.Methods HPLC-PDA method was adopted.The chromatographic conditions were as follows:Hypersil ODS2 analytical column,the mobile phase consisting of 0.05 %phosphate acid and acetonitrile with gradient elution,detecting wavelength at 254 and 280 nm,the flow rate being 1.0 mL/min and the temperature of the column at 30 ℃.Results The methodological results were good.The results of dual-wavelength fingerprint chromatogram showed the all-around information of the fingerprints at 254 and 280 nm.The similarity of 10 batches of BuzhongYiqi Decoction was over 0.98.Conclusion Dual-wavelength fingerprint chromatogram can realize the analysis of a formulas as a whole,which supplies references for improving the quality control of BuzhongYiqi Decoction.
