Artificial intelligence technology encompasses a broad intersection of disciplines including informatics,biolo-gy,and logic,and its application in the healthcare field has garnered significant attention in recent years.Electronic medical re-cords(EMRs)contain vast amounts of medical data with potentially immeasurable medical value.Utilizing artificial intelligence technology to mine this potential value can assist clinicians in decision-making,improve diagnostic and treatment efficiency,and enhance service quality,which is of great significance for the development of the healthcare sector.This paper introduces the ap-plication of artificial intelligence technology in data mining of electronic medical records and quality control of medical record con-tent.It also discusses the existing limitations and challenges,while providing insights into future developments.

Objective To assess the significance of insulin tolerance test(ITT) in clinical diagnosis of adult growth hormone deficiency(GHD).Methods Eighty-two patients with an established diagnosis of adult GHD [53males,29 females,mean age (30.9 ± 12.3) years (18-65 years)] were reviewed retrospectively for evaluating the GH response to ITT in the General Hospital of the People' s Liberation Army.Control data for peak GH after ITT were obtained in 15 healthy subjects [9 males,6 females,mean age (26.7 ± 5.6) years (22-41 years)].Receiver operating characteristic (ROC) curve analysis and the area under the curve (AUC) were used to evaluate the diagnostic cut-off point of peak GH and GH increment response to ITT.Results (1) Mean peak GH response to ITT was significantly higher in 15 controls compared with 82 patients (the median 14 μg/L vs 0.62 μg/L,P =0.001).The cut-off point of the peak GH(chemiluminescent immunoassay,CLIA) response to ITT in adult GHD was 4.935 μg/L (AUC 0.993).(2) Mean GH increment was significantly higher in 15 controls compared with 82 patients (the median 13.17 μg/L vs 0.19 ug/L,P＜0.001).The cut-off point of the GH increment was 4.088 μg/L(AUC 0.937),with a 91.5％ sensitivity and 100％ specificity.(3) The peak GH showed even higher diagnostic value than the GH increment after ITT.(4)The above mentioned cut-off points (peak GH less than 4.935 μg/L and 5 μg/L) had a coincidence with a 95.1％ sensitivity and 100％ specificity,respectively.Conclusion The current guidelines for the diagnosis of adult GHD based on the optimal cut-off point of the peak GH(CLIA) response to ITT less than 5 μg/L turned to be of reliable diagnostic value in our country.

OBJECTIVE To establish an HPLC method for determination of the related substances in papaverine hydrochloride. METHODS NanoChrom ChromCore 120 C8 column was used; the mobile phase A consisted of 3.4 g·L−1 potassium dihydrogen phosphate aqueous solution, adjust pH to 3.5 with phosphoric acid-acetonitrile(90∶10), the mobile phase B was methanol, with gradient elution at the flow rate of 0.8 mL·min−1; the detection wavelength was 238 nm; the column temperature was 50 ℃. RESULTS The minimum separation between the main component and each impurity was >1.5; Papaverine and its thirteen impurities showed a good linear relationship in the self-concentration range(r>0.999); and the average recoveries were 93.1%−101.2% with RSDs of 2.3%−8.1%. CONCLUSION The method is accurate, sensitive and reliable, which is suitable for the determination of related substances in papaverine hydrochloride.

A series of 2-(((5-akly/aryl-1-pyrazol-3-yl)methyl)thio)-5-alkyl-6-(cyclohexylmethyl)-pyrimidin-4(3)-ones were synthesized and their anti-HIV-1 activities were evaluated. Most of these compounds were highly active against wild-type (WT) HIV-1 strain (IIIB) with EC values in the range of 0.0038-0.4759 μmol/L. Among those compounds, had an EC value of 3.8 nmol/L and SI (selectivity index) of up to 25,468 indicating excellent activity against WT HIV-1. anti-HIV-1 activity and resistance profile studies suggested that compounds and displayed potential anti-HIV-1 activity against laboratory adapted strains and primary isolated strains including different subtypes and tropism strains (ECs range from 4.3 to 63.6 nmol/L and 18.9-219.3 nmol/L, respectively). On the other hand, it was observed that those two compounds were less effective with EC values of 2.77 and 4.87 μmol/L for HIV-1A (K103N + Y181C). The activity against reverse transcriptase (RT) was also evaluated for those compounds. Both and obtained sub-micromolar IC values showing their potential in RT inhibition. The pharmacokinetics examination in rats indicated that compound has acceptable pharmacokinetic properties and bioavailability. Preliminary structure-activity relationships and molecular modeling studies were also discussed.
