In July 2024,the Diagnosis Related Groups(DRG)2.0 is released based on the Notice from the National Healthcare Security Administration on Issuing the DRG 2.0 and Deepening the Relevant Work.Compared with DRG 1.1,version 2.0 was established based on a wider range of suggestions regarding the Adjacent Diagnosis Related Groups(ADRG),Major Comorbidity or Complication(MCC),and Comorbidity or Complication(CC)from various institutions.A list of disease diagnoses and surgical operations that are not used as grouping rules was compiled,and grouping efficacy was further improved by upgrading the algorithms for MCC and CC with the help of AI.Meanwhile,it is necessary to pay more attention to the number of cases of ADRG,the better methods to list the MCC/CC,the suggestions of various doctors and continuously standardize the data and update the grouping scheme of DRG.

Objective To establish a quality standard for Ganmao granules of hospital preparations .Methods Radix Scutellariae ,cortex phellodendri and radix bupleuri were identified by thin layer chromatography (TLC) qualitatively .High performance liquid chromatography (HPLC) was used for the content of baicalin .The determination was performed on Agilent HC-C18 column (250 mm × 4 .6 mm ,5 μm) at 30 ℃ with mobile phase composed of methanol-0 .2% phosphoric acid (43∶57) at the flow rate of 1 .0 ml/min .The detection wavelength was set at 280 nm .Results In TLC chromatograms ,the spectra of different test products had spots of the same color at corresponding sites ,with no interference from negative control .A good linearity range of baicalin was 1 .81~72 .40 μg/ml (r=0 .999 9) .The average recovery rate was 98 .55% (RSD=1 .91% ,n=9) .Conclusion The quality standard was established and the method of identification has good reproducibility .The method of determination of baicalin content improved the controllability of formulated quality of Ganmao granules .

OBJECTIVE:To establish the quality standards for Shenshuaikang granule. METHODS:TLC was used for the quali-tative identification of Astragali Radix and Rhei Radix et Rhizoma in the preparation. HPLC was used for the contents determina-tion of emodin and chrysophanol ,the column was Agilent HC-C18 with mobile phase of methanol-0.1% phosphoric acid (85:15 , V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 254 nm,the column temperature was 30 ℃ and the injection vol-ume was 10 μl. RESULTS:TLC showed clear spots and good separation. The linear range was 1.9-60.8 μg/ml for emodin(r=0.999 9, n=6) and 1.6-51.2 μg/ml for chrysophanol (r=0.999 9),RSDs of precision,stability and reproducibility tests were lower than 3%,recoveries were 95.76%-103.66%(RSD=2.83%,n=9)and 97.24%-104.34%(RSD=2.65%,n=9),respectively. CONCLU-SIONS:The standard can be used for the quality control of Shenshuaikang granule.

Objective To explore the association between L-selectin gene P213S polymorphism and angina pectoris.Methods L-selectin gene P213S polymorphism in 138 patients with angina pectoris and 156 controls was detected by polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP).The relationship between gene polymorphism of L-selectin and levels of serum lipids were also studied.Results L-selectin genotype frequencies of PP,PS,SS were 60.1%,36.3%,3.6% and 44.9%,48.1%,7.0% in angina pectoris group and control group respectively.Allele frequencies of P,S were 78.3%,21.7% and 68.9%,31.1% in angina pectoris group and control group respectively.There was significant differences of frequencies of genotype and allele of L-selectin P213S polymorphism between angina pectoris group and control group(P
