ABSTRACT
Background:Malnutrition is common in patients with cancer, whichadversely affectsthesurvival and quality of life ofcancer patients.However, there is no national data on the prevalence of malnutrition inChinese cancer patients. Thisstudy aims to evaluate the prevalenceof malnutrition and quality of life(QOL)ofChinese patients with localregional, recurrentor metastatic cancer,to address the prognostic value of nutritional status and QOLon the survival of cancer patients in China and to validate the patient-generated subjective global assessment (PG-SGA) questionnaire in Chinese cancer patients.Methods:Thisisanobservational,multi-centered,and hospital-based prospective cohort study.We aimed to recruit 50,000 cancer patients (age 18and above)overan 8-year period.Data collection will occur within 48hrafter patientsare admitted to hospital, 30-days after hospital admission, and the follow-up will be conducted1-8years after enrolment. The primary outcomeisoverall survival, and secondaryoutcomes arelength of hospital stay and hospital costs. Factors measured are demographic characteristics, tumor characteristics, anthropometry measurements,hematological measurement, body composition, PG-SGAscores,Karnofsky performance status scores,and QLQ C30 scores. This protocol wasapproved by local ethical committees of all the participant hospitals.Conclusions: This multi-centered, large-scale, long-time follow-up prospective study will help diagnose malnutrition in cancer patients in China, and identify the related risk factors associated with the negative outcomes. The anticipated results will highlight the need for a truly scientific appraisal of nutrition therapy, and help to improve outcomes among cancer patients in China.Trial Registration: The trial has been registered with the Chinese Clinical Trial Registry, ChiCTR1800020329.

ABSTRACT
Objective:To develop a UPLC method for the simultaneous determination of 5 components in Guilong Kechuanning tablets including paeoniflorin, berberine hydrochloride, alkaloid, cinnamic acid and cinnamaldehyde. Methods:An ACQUITY UPLC BEH C18(2.1 mm ×100 mm,1.7 μm)chromatographic column was used;the mobile phase was acetonitrile(A)–0.1% formic acid solution (B) with gradient elution (0-10 min, 85% A;10-13 min, 10% A;13-15 min, 85% A) at a flow rate of 0. 4 ml·min-1, the detection wavelengths were:0-1. 8 min, 230 nm;1. 8-6. 0 min, 345 nm;6. 0-9. 0 min, 285 nm;9. 0-12. 0 min, 345 nm, and the column temperature was 30℃. Results:The linear range of paeoniflorin, berberine hydrochloride, alkaloid, cinnamic acid and cinna-maldehyde was 0. 060-1. 202 μg(r=0. 9999),0. 100-2. 010 μg(r=0. 9999),0. 040-0. 794 μg(r=0. 9994),0. 015-0. 302 μg(r=0.9999) and 0.042-0.850 μg(r =0.9999), the average recovery (n = 6) was 99.63%,99.26%,100.17%,98.80% and 100. 26%, and the RSDs were 0. 39%,0. 97%,0. 73%,1. 00% and 0. 71%, respectively. Conclusion:The method is simple, accu-rate and reproducible. It can be used for the quality control of Guilong Kechuanning tablets.

ABSTRACT
ObjectiveTo evaluate the parenteral nutrition formula's character of all-in-one-mixed preparation and pre-mixed preparation applied for hospitalized patients in China.MethodsWe collected parenteral nutrition (PN) prescriptions in hospitalized patients with various diseases at dispensing centers of 6 hospitals in different areas of China. Statistic analysis was made by nutrients application, total liquid, nonprotein calories, total nitrogen, ratio of non-protein calories and total nitrogen, and ratio of glucose and fat. A comparison was made between all-in-one-mixed and pre-mixed preparation as to all the indices.Results The nutrients supply in all-in-one-mixed PN preparation, as well as in the pre-mixed PN preparations of 3 different energy degrees can meet the basic nutrition requirements of most patients. The total nitrogen supply in all-in-one-mixed PN prescriptions meets nutrition requirements in most patients, but the ratio of non-protein calories and total nitrogen[( 180-250) : 1]and the ratio of glucose and fat (0. 56-1.26)were significantly different from what a doctor would recommend[( 100-150) : 1, 1.0]. While the ratios in the pre-mixed PN preparation on 3 different energy degrees are more consistent with recommeded values,which are at 167 and 0. 8 respectively.ConclusionsAll-in-one-mixed and pre-mixed PN preparation have their own individual advantages and limits, and both of them can meet the requirements of most hospitalized patients. More attention should be paid to the nutrients proportion when doctors prescribe all-in-one-mixed PN preparations.
