Objective To analyze the clinical profiles of lupus mesenteric vasculitis (LMV).Methods Thirty-six SLE patients diagnosed with LMV and 72 SLE patients (1:2) without LMV at West China Hospital between October 2009 and January 2012 were enrolled.The imaging,clinical manifestation,laboratory examinations data were analyzed retrospectively.Quantitative differences were analyzed by the Student's t and Z tests and qualitative data were compared with Chi-square.P value less than 0.05 was considered as statistically significant.Results ① The prevalence of LMV in patients with SLE was 1.2％(36/3 051),while 47％(17/36) as the initial symptom of SLE.Thirty-six LMV patients were all female.The prevalence of abdominal pain was 78％(28/36),nausea or vomitting was 58％(21/36),abdominal distension was 50％(18/36),diarrhea was 47.2％ (17/36),intestinal perforation was 3％ (1/36) and incomplete obstruction was 8％ (3/36).Enhanced CT scan showed 81％(25/31) patients suffered from intestinal dilation and (or) mesenteric edema;SLEDAI (17±5),C3 (0.44±0.25) g/L,C4 (0.10±0.09) g/L,Z value on above items were 4.30,-3.85 and-2.94 respectively compared to SLE patients without LMV,and all P＜0.05,the differemces were significant.In addition,Also,the proportion of ANA and anti-ENA antibody showed no significant difference.68.6％(13/36) patients were also diagnosed with lupus nephritis;61％(22/36) patients were treated with methylprednisolone more than 200 mg/d resulting in relief of symptom.Conclusion Female patients with SLE may be more likely to suffer from LMV;Enhanced abdominal CT scan is still essential to the diagnosis of LMV.LMV is correlated with urinary system malfunction.LMV always occurs in active lupus with low C3 and C4 level.More than half patients should be treated with corticosteroid and cyclophosphamide pulse therapy.

The purpose of this study is to investigate the enantioselectivity of norgestrel (NG) transdermal permeation and the potential influence of linalool and lipids on the enantioselectivity. In vitro skin permeation studies of NG across the excised rat skins were performed with Valia-Chien diffusion cells, and the permeation samples were analyzed by enantioselective HPLC. The possible enantioselective permeation of NG across intact rat back skin and lipids extracted rat back skin and the influence of linalool were evaluated. The skin permeation rate of dl-NG was two times higher than that of l-NG when donor solutions (EtOH/H2O 2 : 8, v/v) containing l-NG or dl-NG. It may be mainly attributed to the solubility discrepancy between enantiomer and racemate. The enantioselective permeation of dl-NG across intact rat skin was observed when the donor solutions containing dl-linalool. The permeation flux of l-NG was 22% higher than that of d-NG. But interestingly, the enantioselective permeation of dl-NG disappeared under the same experimental condition except that the lipid extracted rat skin was used. Attenuated total reflection-fourier transform infrared spectroscopy analysis of stratum corneum showed that the wave number for asymmetric CH2 stretching vibrations of lipids treated with dl-linalool was greater than that of the control. The results indicated that the enantioselective permeation of NG may be contributed by the interaction between dl-linalool and lipids. More than half of lipids were composed of ceramides. The stereospecific interaction maybe existed among chiral enhancer (linalool), lipids (ceramides) and/or chiral drugs (NG).

Abstract: Objective　To explore the correlation between monocyte to high-density lipoprotein cholesterol ratio (MHR) and insulin resistance (IR) in male patients with type 2 diabetes mellitus (T2DM) combined with metabolic-related fatty liver disease (MAFLD). Methods A total of 454 male patients with T2DM combined with MAFLD in National Metabolic Management Center (MMC) of the Affiliated Hospital of Jiangsu University from May 2018 to July 2020 were enrolled. The general clinical data of subjects were collected, blood routine and biochemical indexes were tested, homeostasis model insulin resistance index (HOMA-IR) was calculated, visceral fat area (VFA) and subcutaneous fat area (SFA) were measured. Accordingtothe MHR quartile, patients were divided into group Q1 (MHR≤0.38), group Q2 (0.380.64) to compare the differences in measured indicators above. In addition, patients were divided into two groups according to HOMA-IR, HOMA-IR<2.5 and HOMA-IR≥2.5, and the differences in MHR were compared. Results The patients were divided into four groups according to MHR:group Q1 (n=115), group Q2 (n=110), group Q3 (n=120) and group Q4 (n=109). Fasting insulin (FINS) were respectively 6.17(4.20,9.76), 7.73(4.94,10.66), 8.92(5.32,11.33) and 9.13(5.25,12.27) mU/L, 2-hour postprandial insulin were 22.75(12.87,39.59), 27.55(16.44,39.77), 30.98(17.46,43.11) and 31.28(18.54,45.92) U/L. HOMA-IR were 3.12(1.63,4.25), 3.72(2.26,4.66), 3.87(2.48,5.44) and 3.95(2.42,5.31). Neutrophil (Neu) were 3.10(2.60,3.70), 3.20(2.50,3.93), 3.60(2.80,4.28), 4.20(3.30,5.00)×109/L. Subcutaneous fat area (SFA) were (181.27±53.60), (192.64±62.41), (199.53±61.40) and (203.69±71.51) cm2. They all increased gradually. However, the levels of high-density lipoprotein cholesterol (HDL-c) [1.18(1.06,1.35), 1.02(0.86,1.17), 0.96(0.80,1.03) and 0.80(0.69,0.92) mmol/L] and low-density lipoprotein cholesterol (LDL-c) [(3.00±0.79), (2.76±0.83), (2.67±0.85) and (2.59±0.92) mmol/L] decreased gradually. Pearson's or Spearman's correlation analysis showed that MHR was positively correlated with FINS, 2-hour postprandial insulin (2hINS), HOMA-IR, VFA and SFA (r=0.190, 0.153, 0.184, 0.114, 0.127, P<0.05). The coronary heart disease history, systolic blood pressure,diastolic blood pressure,fasting plasmaglucose (FPG), FINS, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood uric acid (Ur), body mass index (BMI), VFA, SFA and MHR of patients in group HOMA-IR≥2.5 were higher than group HOMA-IR<2.5 (P<0.05). Conclusion　MHR is positively correlated with IR in male patients with T2DM combined with MAFLD, and as MHR increases, the degree of IR is higher.

The objective of this work was to investigate the effect of six individual strains of fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal (CSM). Six groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. capsuligena ZD-1, C. tropicalis ZD-3, S. cerevisae ZD-5, A. terricola ZD-6, A. oryzae ZD-7, or A. niger ZD-8. One not inoculated group (substrate) was used as a control. Levels of initial and final free gossypol (FG), crude protein (CP), amino acids (AA) and in vitro digestibility were assayed. The experiment was done in triplicate. The experimental results indicated that microbial fermentation could greatly decrease (P<0.05) FG levels in CSM. The detoxification efficiency differed between the species of microorganisms applied. From the perspective of reducing CSM potential toxicity, C. tropicalis ZD-3 was most successful followed by S. cerevisae ZD-5 and A. niger ZD8. They could reduce FG levels of CSM to 29.8, 63.07 and 81.50 mg/kg based on DM (dry matter), respectively, and their detoxification rate were 94.57%, 88.51% and 85.16%, respectively. If crude protein, amino acids content and their in vitro digestibility were also taken into account, A. niger ZD-8 may be the best choice. The CP content of CSM substrate fermented by C. tropicalis ZD-3 and A. niger ZD-8 were improved by 10.76% and 22.24%; the TAA (total amino acids) contents were increased by 7.06% and 11.46%, and the EAA (essential amino acids) were raised by 7.77% and 12.64%, respectively. Especially, the levels of methionine, lysine and threonine were improved greatly (P<0.05). The in vitro CP digestibility of CSM fermented by C. tropicalis ZD-3 and A. niger ZD-8 was improved by 13.42% and 18.22%, the TAA were increased by 17.75% and 22.88%, and the EAA by 16.61% and 21.01%, respectively. In addition, the in vitro digestibility of methionine, lysine and threonine was also improved greatly (P<0.05).
