3.Development and verification of a RP-HPLC method for determination of residual trifluoroacetic acid in human interferon alpha 2b stock solution
Chinese Journal of Biologicals 2024;37(8):996-1001
ObjectiveTo develop and verify a reversed-phase high performance liquid chromatography(RP-HPLC)method for the determination of residual amount of trifluoroacetic acid(TFA)in human interferon alpha 2b(hIFNα2b)stock solution,and preliminarily apply the method.MethodsThe conditions of liquid chromatography were as follows:ZORBAX300SB-C18 column(4. 6 mm × 250 mm,5 μm);mobile phase:0. 08% phosphoric acid(pH 3. 0)+ 5. 0% methanol solution;detection time:6 min;flow rate:0. 8 mL/min;column temperature:35 ℃;UV wavelength:210 nm;injection volume:20 μL;isocratic elution. The system adaptability,linearity,specificity,accuracy,precision,limit of quantitation(LOQ),limit of detection(LOD)and durability of the method were verified. The TFA residues in three batches of hIFNα2b stock solution samples were determined by the developed method and composite column Comixsil ACRP(100 mm × 4. 6 mm,5 μm).ResultsThe linearity of TFA was good in the range of 10-300 μg/mL(R2= 0. 998 4). The average spike recovery rate was 101. 8% and RSD was 2. 68%. The RSDs of repeatability and intermediate precision verification were 0. 46% and0. 45%,respectively. The LOQ was 10 μg/mL,and the LOD was 2 μg/mL. The slight fluctuation of pH of organic solvent,buffer salt and temperature of column under the specified conditions had no obvious influence on the detection results,and the peak area was affected when the detection wavelength changed. In addition,TFA residues were not detected in three batches of hIFNα2b stock solution by two methods.ConclusionThe developed RP-HPLC method has good system adaptability,specificity,accuracy,precision and durability,and can be used for the determination of TFA residues in hIFNα2b stock solution.

China Pharmacy 2005;0(24):-
OBJECTIVE: To provide reference for research & development and application of pill preparation. METHODS: Our understanding on the statement "Pill, Is Sluggish" was come up with, and the pertinetn literature and research results were analyzed and summarized. RESULTS: The statement "Pill, Is Sluggish" is not only the description of the traditional pill's dosage-form characteristic, but also contains the requirement on administration method. It is a relative description. There is also difference in speed of taking effect between different kinds of pills. Its origin contains the factor of dosage as well as the factor of dosage-form; It does not apply to some new type pills. CONCLUSION: The connotation of "Pill, Is Sluggish" is extremely rich, which should be viewed relatively, comprehensively and developmentally so as to continuously enrich and develop the dosage form theory of Chinese materia medica and make pills serve better for the clinic.

8.EFFECTS OF STATIC EXERCISE AND DYNAMIC EXERCISE ON SYSTOLIC TIME INTERVALS (STI) IN CHILDREN
Chinese Journal of Sports Medicine 1982;0(02):-
The purpose of this study was to investigate STI changes resulting from static and dynamic exercises in boys, 9-10 years old, so as to reveal the effects of physical work of different types and loads on the heart function.Our research showed that the effects of static load and dynamic load on STI in children were different. After dynamic exercise all items of STI changed significantly and PEP/LVET decreased significantly. No PEP change was found after static exercises (50% and 80% max load). Static exercise of 50% max load resulted in no IVCT change, but static exercise of 80% max load resulted in very significant change of IVCT, and the longest recovery period was found afterwards. Thus, 80% static exercise would result in a heavy, transient heart load in children.Our research also showed that the changes of HR?systolic blood pressure?LVET after dynamic load and static load were significantly different indicating that oxygen consumption in heart muscles was higher during dynamic exercise and the effect of dynamic exercise on heart was stronger.

Objective To explore the application effect of strengthened pulmonary rehabilitation exercise in lung cancer patients with severe pulmonary ventilation dysfunction during perioperative period. Methods A total of 96 patients receiving lung cancer radical treatment under thoracoscope in our hospital during March 2013 to April 2015 were collected, and for all these patients, pulmonary function test before treatment showed that there was severe pulmonary ventilation dysfunction. The patients were divided into the routine group and the intervention group by random digital table method, with 48 patients in each group;patients in the routine group received routine perioperative nursing, and those in the intervention group received the strengthened pulmonary rehabilitation intervention plan; change in pulmonary function before treatment, duration of mechanical ventilation, time of oxygen therapy, retaining time of chest tube, length of hospital stay and occurrence of complications after treatment were compared between the two groups. Results After strengthened pulmonary rehabilitation intervention in the intervention group, the FVC was (2.63±0.47) L, the MVV was(53.14±9.40) L, the DLCO was(19.26±2.63) ml·min-1·mmHg-1, the VO2 was (23.15±4.36) ml/kg and the O2Pulse was(10.98±2.52) ml·min-1·times-1, Which were significantly improved compared with those before treatment, (2.41±0.40) L,(46.98±8.91) L,(17.56±2.83) ml·min -1·mmHg -1, (20.17±4.35)ml/kg and(9.82±2.07) ml·min-1·times-1, t=2.521, 3.512, 3.112, 3.421, 2.515, P<0.01 or 0.05. While there was no obvious change in the above- mentioned indexes of those in the routine group. After treatment of patients in the intervention group the duration of mechanical ventilation was (9.42±3.17) hours, time of oxygen therapy was (76.23±21.18) hours, retaining time of chest tube was (3.58±1.44) days and length of hospital stay was (6.62±2.14) days, which were significantly shorter than those in the routine group, (17.29±4.79) hours,(92.14±24.29) hours, (4.73±2.15) days and(8.68±2.96) days. The occurrence rates of complications such as pulmonary infection, pulmonary atelectasis and respiratory failure were 12.50%(6/48),10.42%(5/48) and 4.17%(2/48)in the intervention group, significantly lower than those in the routine group, 41.67%(20/48),29.17%(14/48) and 18.75%(9/48), χ2=10.338, 5.315, 5.031, P <0.01 or 0.05. Conclusions Strengthened pulmonary rehabilitation intervention can improve pulmonary function of lung cancer patients with severe pulmonary ventilation dysfunction before treatment, reduce the occurrence rate of post- operative complications and enhance safety during the perioperative period; it is worth of being further promoted clinically.
