Objective To investigate the clinical efficacy of nephrotic syndrome in children adjunctively treated by underatured lactalbumin.Methods Thirty-six cases of nephrotic syndrome were studied for about 1 year.The changes in red blood cells of reduced glutathione(GSH) were analyzed in 18 cases of underatured lactalbumin treatment group and 18 cases of control group.The clinical presentations were observed in both groups.Results GSH levels increased in underatured lactalbumin treatment group when compared with control group.The frequency of relapse and upper respiratory tract infection in underatured lactalbumin treatment group were significantly reduced compared with control group.Conclusion Underatured lactalbumin can provide support for the potential use of an antioxidant therapy in these patients.

Objective: To investigate the vaccine potency of GM-CSF anchored B16 tumor cells. Methods: In this study, mGM-CSF was expressed on surface of B16 mice melanoma cells by GPI-modifying. C57BL/6 mice were inoculated with GM-CSF anchored cells and wide-type B16 cells to evaluate whether the GM-CSF anchored cells could elicit a protective and systemtic antitumor response. Results: GM-CSF anchored cells resulted in remarkable loss of tumorgenicity in syngenetic mice. The tumor occurrence rate of GM-CSF anchored B16 cells was 58. 8% on C57BL/6 mice with 1 ? 106 B16 cells/mice inoculated ( n = 12) and that of wide-type B16 cells was 100% , The C57BL/6 mice receiving inoculation with 5 ? 105GM-CSF anchored cells/mice never grew tumor. These mice were challenged with wide-type B16 cells, and only a minority of mice grew tumor after wide-type B16 cells inoculation. Conclusion:GM-CSF protein anchored cells could elicit a protective and systemtic antitumor responses.

Piroxicam has polymorphism. Different crystalline forms can exhibit different physicochemical properties and biological activities. Analysis of the intermolecular interactions is essential to reveal the formation mechanism and differences of polymorphs. In this paper, Hirshfeld surface analysis and semi-empirical methods were used to calculate and analyze the intermolecular interactions in seven polymorphic forms of piroxicam. The results show that the Hirshfeld surface analysis method can clearly and intuitively reveal the intermolecular interactions, among which H…H, O…H/H…O and N…H/H…N interactions account for 95% of the total energy. There are differences in the proportion and distribution of the forces of different crystal forms. The energy calculation shows that the lattice energy of the hydrate is significantly lower than that of the anhydrous forms, and in the specific energy distribution, the contribution of the dispersion force is the most prominent. Further interaction energy analysis was found that within the distance of 3.8 Å from the center of the piroxicam molecule, different crystalline forms of piroxicam molecule have different interaction energies with surrounding molecules.

The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

Four salts of ticagrelor, ticagrelor-3,5-dinitrobenzoic acid, ticagrelor-pyrazinamide, ticagrelor-D-proline and ticagrelor-L-proline were prepared by solvent suspension and liquid-assisted grinding to improve the solubility of ticagrelor. The compounds were characterized by powder X-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimetry, nuclear magnetic resonance spectroscopy, elemental analysis, and the intermolecular salt-bonding forces were analyzed. The equilibrium solubility of salts and pure drug in hydrochloride buffer pH 1.2 and phosphate buffer pH 6.8 were measured by high-performance liquid chromatography. Ticagrelor was salted with 3,5-dinitrobenzoic acid, pyrazinamide, D-proline, L-proline all in a stoichiometric ratio of 1∶1; with the exception of ticagrelor-D-proline, the solubility of the other three salts provided significantly improved solubility in hydrochloride buffer pH 1.2, and the equilibrium solubility of ticagrelor-3,5-dinitrobenzoic acid was increased by approximately 1.7 folds as compared to pure drug. Salt-forming technology is convenient and can improve the solubility of ticagrelor.

Objective To observe the dynamic serological test results of 28 patients with acute brucellosis,and to investigate the relationship between serological test results and diagnosis,curative effect and prognosis of brucellosis.Methods Twenty eight patients(infected with sheep brucellosis) with acute brucellosis in the Department of Brucellosis in Heilongjiang Provincial Land Reclamation Headquarters General Hospital were selected as research subjects,and their serological changes were tested by means of tube agglutination test (SAT)and clinical outcomes were compared before and after each stage of treatment.In addition,symptoms of fever,weakness,sweating,joint pain,swollen lymph nodes and biochemical parameters [alanine aminotransferase (ALT),lactate dehydrogenase (LDH)] were also tested 3,6 and 9 weeks after the treatment.Results Antibody titer reached the peak at the third week,1 ∶ 400(++),which accounted for 39.29％ (11/28); 2857％(8/28) of the patients became negative at the sixth week; 50.00％ (14/28) became negative at the ninth week.Before the treatment,20(71.43％) patients had the symptom of fever,8 (28.57％) patients had the symptom of hyperhidrosis,28 (100.00％) patients had the symptom of joint pain,7(25.00％) patients had the symptom of lymph node enlargement,28 (100.00％) patients' ALT was elevated,and 26(92.86％) patients' LDH was elevated.After three weeks of treatment,except the three patients (10.71％) who occasionally had fever,the rest of the patient's temperature was returned to normal.Also the numbers of patients with the symptoms of fatigue,sweating and joint pain were significantly reduced,and specifically,the conesponding number was 13(46.43％),2(7.14％),and 21 (75.00％)patients,respectively.ALT and LDH returned to normal(only one patient's ALT was out of the range).At the sixth week,all the patients' symptoms of fever and hyperhidrosis disappeared.The number of patients with the symptoms of joint pain and lymph node enlargement reduced to 12(42.86％) and 3(10.71％),respectively.The results of biochemical tests(ALT and LDT) returned to normal.At the ninth week,most patients' clinical symptoms disappeared.A few patients still had the symptoms of weakness[2(7.14％)] and joint piin[6(21.43％)].Conclusions After effective treatment,antibody titer of patients decreases rapidly,at the same time,the clinical symptoms improve quickly.There is a parallel relationship between the change of antibody titer and clinical symptoms.It is demonstrated that the appearing time of brucellosis specific antibodies,the ampfitude and speed of change of antibody titers can be used in diagnosis,therapeutic evaluation and prognosis of the disease.
