An on-line solid phase extraction-high performance liquid chromatography ( SPE-HPLC ) system was applied in the plasma pharmacokinetic study of highly active anti-cancer compound tyrosine kinase inhibitors (TEB-415) in mouse. The on-line SPE-HPLC method associated with Ultimate3000 system which was applied to the determination of the blood drug level of TEB-415 in mouse plasma. C18 column ( Venusil MP, 150 mm × 4. 6 mm, 5μm) was used as analytical column and the mobile phase consisted of acetonitrile-5 mmol/L monopotassium phosphate buffer ( pH 3 . 5 ) at a flow rate of 1 . 0 mL/min was used as the isocratic elution. An MF Ph-1 column (10 mm×4 mm, 5 μm) was used as on-line SPE column, and water and water-acetonitrile were used as the washing solvent and elution solvent respectively. The detection wavelength was set at 262 nm. The pharmacokinetic parameters were calculated by WinNonlin 5. 2 software. The linear range of the calibration curve was between 100 and 20000 μg/L, and the limit of qualification was 20 μg/L. The extraction recovery was between 90 . 5% and 94 . 6%. The RSD of intra-day and inter-day precision was less than 3. 5%. The accuracy of short-term stability, freeze-thaw stability and long-term stability were between 91. 49% and 101. 96%. After oral medication, the mean peak time (Tmax) of TEB-415 in mice was 5. 29 h, and the mean maximum concentration ( Cmax) was 3403μg/L. The area under the curve ( AUC) of TEB-415 was 24600 μg/L·h. This drug's mean half-life was 3. 84 h, and its mean retention time (MRT) was 6. 56 h. These parameters suggested that TEB-415 had appropriate rate of absorption and elimination with preferable bioavailability.

Objective:To investigate the expression of maternally expressed gene 3 (MEG3), a long non-coding RNA gene, in gastric can-cer tissues;determine the relationship of MEG3 with the prognosis of gastric cancer;and explore the relationship between MEG3 and apoptosis-associated protein P53 as well as murine double minute 2 (MDM2). Methods:Fifty-five consecutive patients with gastric cancer admitted to Qingdao Municipal Hospital for surgical treatment from September 2012 to June 2013 were included in this study. Gastric cancer and paired normal tissues were collected. The expression of MEG3 was tested through real-time quantitative poly-merase chain reaction (qRT-PCR). Western blot analysis was used to detect the expression of P53 and MDM2 in gastric cancer and eval-uate their correlations with MEG3. Results:The expression of MEG3 decreased in cancer tissues (7.98±0.19) relative to the correspond-ing normal tissues (9.47±0.18) (P<0.05). P53 and MDM2 showed negative relationships in the gastric cancer and normal tissues. A posi-tive relationship was found between P53 and MEG3 (r=0.591, P<0.05), whereas a negative relationship was found between MDM2 and MEG3 (r=?0.346, P<0.05). The median survival time was significantly prolonged in patients with high MEG3 expression compared with patients with low MEG3 expression. Conclusion:MEG3 exerts an inhibiting effect on the development of gastric cancer. MEG3, P53, and MDM2 may have important relationships in the biological mechanisms of gastric cancer development. Detecting the expression level of MEG3 may be useful for the prognosis of gastric cancer.

Objectives To analyze the diagnosis and management of steroid-resistant nephrotic syndrome (SRNS) accompanied with irreversible leukoencephalopathy in children. Methods The clinical, laboratory and imaging data were retrospectively analyzed in a SRNS child accompanied with irreversible leukoencephalopathy. A literature review was performed. Results After clinical diagnosis of SRNS, glucocorticoid, immunosuppressant, and hemodialysis were administrated for 10 months. During the course of treatment, the seizures, visual problems, and hypertension were repeatedly occured. The cranial MRI showed bilateral occipital parietal lobe hyperintensity and right frontotemporal lobe hyperintensity on T2-weighted imaging and bilateral occipital parietal lobe hypointensity on T2-Flair imaging, which indicated that encephalomalacia was accompanied with gliosis. Conclusions A variety of reasons may induce leukoencephalopathy in children. The accompanied irreversible leu-koencephalopathy should be strongly considered in management of SRNS.

Objective To investigate the symptoms and the needs of transitional care for the patients with lung cancer at the intermission of chemotherapy and provide references for the symptom management and carrying out transitional care. Methods Totally 156 patients with lung cancer were investigated by questionnaire survey. Results With the increase of chemotherapy, symptoms such as cough, sputum, dyspnea were relieved after chemotherapy(F=18.266, 20.463, 17.371, P < 0.05), but symptoms like fatigue, nausea, vomiting, loss of appetite, sleep uncomfortable were worse than before(F=15.821, 20.116, 16.439, 13.541, 9.528, P<0.05,<0.01). Negative emotions like bitterness and sadness had no obvious change. Symptoms affected the patients′mood, the incidence and severity were higher after chemotherapy(χ2=43.162, F=11.683, P < 0.05), as for general activity and walking, the incidence and severity were higher after the first cycle chemotherapy and the second cycle(χ2=42.589, 37.689, 39.125, F=9.148, 15.325, 14.758, P < 0.05), but after 4 cycles of chemotherapy, it did not change significantly (P>0.05). 79.49%(124/156)patients did not know the content and function of transitional care, 98.72%(154/156)patients hope to get transitional care through the hospital. Conclusions Symptoms by side effects were getting worse for patients with lung cancer and influenced their daily life. Patients got to know less about transitional care, however they had a strong need for transitional care. We should
reinforce the management of symptoms and transitional care to improve their quality of life.

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.
