Chinese herbal formulas can well present the characteristics of traditional Chinese medicine (TCM) with their simple, convenient, inexpensive and effective uses. However, due to the high cost of production, manufacturing pharmacies inside the hospital closed down one after another, which rendered the difficult situation of developing preparation of Chinese herbal formulas. The Pudong New Area of Shanghai, as a pilot region for comprehensive reforms on national development of TCM, vigorously explores the standardized research on and application of hospital-made Chinese herbal formulas. The Health Bureau of the Pudong New Area, based on the Shuguang Hospital, has established a clinical evaluation center for hospital-made Chinese herbal formulas. Through screening, manufacturing, quality control, unified allocation, and standardized clinical evaluation, the clinical evaluation center has summarized its experience on these processes.

Objective To investigate the effect of high glucose on the expression of liver X receptors (LXRs) and ATP-binding cassette transporter A1 (ABCA1) in human macrophages (THP-1 cell line). Methods THP-1 monocytes were differentiated into macrophages by induction of phorbol 12, 13-dibutyrate (PMA). Surface markers of macrophages were identified by CD68 immunohistochemistry. The macrophages were cultured with different concentration (5.6, 11.1, 22.2 and 33.3 mmol/L) of glucose and different time (0, 0.5, 2, 6, 12, 24, 48, 72 h). Real time PCR and Western blotting methods were used to examine the mRNA and protein expression of LXRs and ABCA1. Results As compared to 5.6 mmol/L glucose, macrophage LXRβ and ABCA1 were decreased significantly at both mRNA and protein levels in dose-and time-dependent manner (P<0.05). Conclusion Hyperglycemia may play a role in the pathogenesis of arteriosclerosis through the inhibition of LXRs and ABCA1 expression in diabetic patients.

Objective:To investigate the malignant imaging characteristics of non-palpable Breast Imaging-Reporting and Data System 3 breast lesions (NPBL BI-RADS 3 breast lesions) with ultrasound-guided core needle biopsy.Methods:From February 2016 to February 2018, the ultrasound characteristics of 161 NPBL BI-RADS 3 breast lesions in Beijing Friendship Hospital, Capital Medical University were retrospectively collected with ultrasound-guided core needle biopsy and pathological examination. According to the pathological results, the patients were divided into two groups: benign group (153 cases) and malignant group (8 cases). Associated risk factors were analyzed retrospectively according to general characteristics and characteristics of the ultrasound report. The Fisher exact probability test was used for single-factor comparative analysis. Significant variables based on univariate analysis were included in multivariate regression analysis, and then logistic regression was used to search for clinical risk parameters and ultrasound malignant signs. The receiver operating characteristic (ROC) curve was plotted with statistically significant factors to evaluate the diagnostic efficacy. In combination with the area under the curve (AUC), the parameter integral critical value, sensitivity and specificity were analyzed.Results:The age≥45 years ( OR=35.036, P=0.012), the maximum lesion diameter of 1-1.3 cm ( OR=25.047, P=0.008) and a aspect ratio of the lesion of 0.56-0.72 ( OR=19.860, P=0.013) could significantly affect the benign and malignant nature of the lesions, could be independent risk factors. The AUCs for constructing ROC curves to assess the diagnostic values of the above-mentioned indices were 0.732, 0.724 and 0.751, respectively; the sensitivity was 87.5%, 62.5% and 75%; the specificity was 58.8%, 82.4% and 75.2%; the positive predictive values was 10.0%, 15.6% and 13.6%; the negative predictive values was 98.9%, 97.7% and 98.3%, respectively. Conclusion:Of the NPBL BI-RADS 3 breast lesions, the malignant risk of lesions with an age≥45 years, maximum diameter of 1-1.3 cm and aspect ratio of 0.56-0.72 is high.

Objective To compare the efficacy and safety of leflunomide (LEF) combined with medium/low dose corticosteroids and full dose of corticosteroids in the treatment of IgA nephropathy. Method Primary IgAN patients diagnosed by renal biopsy with 18?65 years old and eGFR≥30 ml·min?1·(1.73 m2)?1 and proteinuria>0.5 g/24 h were enrolled in a prospective controlled clinical study. They were randomly divided into leflunomide combined with medium/low dose corticosteroids (LEF group) and corticosteroids alone (steroid group). The primary outcomes were (1) end stage renal disease or dialysis (2) 50% increase in serum creatinine above the baseline. Secondary outcome was the remission of proteinuria. Results Ninety patients completed the follow?up. The 24?hour proteinuria at baseline were 2.00(1.10, 2.88) g and 1.87(1.13 ,3.08) g in LEF group and steroid group respectively. Compared with baseline, it was significantly decreased in both groups at 6 months [0.30(0.11, 0.93) g, 0.30(0.14, 1.33) g] and 12 months [0.30(0.09, 0.82) g, 0.32(0.14, 0.66) g], (P<0.05). Estimated glomerular filtration rate (eGFR) at baseline, 6 months and 12 months were (80.39 ± 28.56), (87.12±28.70) and (88.20±30.26) ml·min-1·(1.73 m2)-1. It was decreased in steroid group (P<0.05), while no significant difference was detected in LEF group[baseline (87.63 ± 27.35), 6 months (86.91 ± 32.45), 12 months (90.06 ± 30.00) ml·min-1·(1.73 m2)-1, P>0.05]. At 6 and 12 months, there was no significant difference in terms of 24?hour proteinuria, serum creatinine and eGFR (CKD?EPI) between groups (P>0.05). There was no statistically significant difference in adverse events between groups during the treatment (9/40 cases in LEF group and 11/50 cases in steroid group, P>0.05). The average follow?up was 79 months, and there was no difference in the renal prognosis between the two groups. Multivariate Cox regression analysis revealed that serum creatinine at baseline and renal interstitial inflammatory cell infiltration predicted the risk of the progress of IgA nephropathy. Conclusion Leflunomide plus medium/low dose corticosteroids has a similar effect as full dose of corticosteroids in IgA nephropathy and does not increase the risk for adverse events during the treatment.
