Objective To investigate and compare the effects of PM2.5 in ambient air samples collected from nickel and nonickel contaminated areas on inflammatory factors in the serum of rats.Methods The air PM2.5 of the nickel-contaminated area and the control area were collected and detected for some major elements.Forty-two male Wistar rats were randomly divided into 10 groups,6 in each,which were respectively instilled with saline,suspended PM2.5 fluid of the nickel-contaminated area and the control area of 3 different doses(1.6,8.0,40.0 mg/kg) through the trachea.The rats were sacrificed 24 hours after being treated with PM2.5.The levels of IL-6,CRP in serum were examined.Results There was no significant difference in the level of PM2.5 between the two areas,the concentration of Ni in the nickel-polluted area was 48.75 times as that in the non-polluted area.A good dose-dependent manner was found in the test of IL-6 in nickel-contaminated groups.CRP was found significantly higher in the nickel-contaminated group and the control group than the saline control group(P

Abstract： With the increasing rise in antidepressant consumption, more and more antidepressants and their metabolic products enter into water and soil environments. This will cause toxicity to animals living in these environments, and antidepressants may be transferred to humans via food chain, leading to human health risks. Based on national and international publications pertaining to environmental pollution and toxic effects of antidepressants during the period between 2005 and 2021, this review summarizes the biological accumulation, acute toxicity, reproductive and developmental toxicity, metabolic effects and biological behavior changes of antidepressants, so as to provide insights into the elucidation of the impact of antidepressants on human health risks.

Objective To investigate the synergistic effect of methotrexate (MTX) and cyclophos phamide (CTX) on cell cycle and cyclin D1 of periphery blood lymphocytes (PBLs) and bone marrow byflow cytometry. Methods Wistar rats were randomly divided into four groups including normal control, MTX and cyclophosphamide combination group, MTX and CTX only treatment groups respectively. PBLs were isolated for flowcytometry analysis for the changes of cell cycle and the expression of cyclin D1 at week 0, week 3,week 9, week18 and week 27. Mice were dissected and the changes of lymphoeytes cell cycle and the expressions of cyclin D1 in the bone marrow were measured at week 0, week 3, week 9, week 18 and week 27 increased and the ratio of phase S cells was decreased (P>0.05). In the CTX treatment group, there was no statistical difference in ratios of each phase. In the MTX and CTX combination treatment group, the proportion of phase G0/G1 cells decreased significantly and the percentage of phase S cells increased in both PBLs and bone marrow ceils (P<0.05). And there was no statistical significant difference in different time points after marrow between different groups or different dissecting time points. Conclusion MTX combined with CTX has been shown to have antagonistic effect on cell cycle. However, this effect is not via the cyclin DI pathway.

Objective To investigate the effects of short term insulin pump intensive therapy on flow-mediated dilation (FMD) in type 2 diabetes mellitus (T2DM) patients with and without vascular complications. Methods Seventy-six patients with T2DM (T2DM group) were divided into 2 subgroups: T2DM1 subgroup (28 patients with vascular complications) and T2DM2 subgroup (48 patients without vascular complications). Meanwhile, 30 healthy cases were selected as NC group. All research subjects accepted high-frequency ultrasound detection on brachial artery for FMD. After insulin pump intensive therapy,FMD in T2DM group was reexamined, fasting insulin was detected and HOMA-IR was calculated. Results Compared with that in NC group, FMD in T2DM group was significantly lower(P＜ 0.01). However, glycosylated hemoglobin (HbA1c ), fasting plasma glucose (FPG ),H0MA-IR and blood fat were significantly higher (P＜0.01 or ＜0.05). Correlation analysis showed that FMD had negative correlation with HbA1c, FPG, HOMA-IR, triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C)(P＜0.01),and had positive correlation with high-density lipoprotein cholesterol (HDL-C). After 2 weeks of insulin pump therapy, the improvement of FMD between the two groups was different. FMD in T2DM1 subgroup increased from (4.25 ± 1.96)% to (4.96 ± 1.36)%(P＞0.05), and FMD in T2DM2 subgroup increased from (4.02 ± 2.35)% to (7.56 ± 2.34)%(P＜ 0.01). Conclusion Insulin pump intensive therapy can evidently improve FMD in T2DM patients without vascular complications.

Objective To prepare Paracetamol (APP) multiloculated implant loaded with poly-lactide-co-glycolide acid (PLGA) and to study the drug release profile in vitro. Methods APP multiloculated implant was fabricated by micro-electro-mechanical system (MEMS), and high-performance liquid chromato graphy (HPLC) measurement was used to investigate in vitro drug release profile. HPLC analysis was carried out by employing C18 column and a mixture of methanol-water (15∶85) as mobile phase. The detection wavelength was 215nm and flow rate was 0.8mL/min. Results With different multiloculated shape, the rate of the drug release in vitro was varied significantly. Moreover, the releasing of APP multiloculated implant with ecto-tetragonum ento-hexagon in vitro conformed to Higuchi equation. Conclusion The technology of the preparations is feasible, and the structural and morphological characteristics of the multiloculated implant have a significant impact on the release speed of the drug delivery system.

Conclusion The selected formulation and preparation of nifedipine liposomes are practicable.

Objective To evaluate the clinical efficacy and safety of methotrexate(MTX),cyclophosphamide(CTX)and MTX plus CTX in patients with active rheumatoid arthritis(RA).Methods In a randomized,single-blinded,controlled study,90 patients were randomly assigned to receive MTX(10～15 mg/w)or CTX(400 mg/2～3 w)or MTX plus CTX(MTX 10～15 mg/w+CTX 400 mg/2～3 w).The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria(achieving an ACR20 response,)at week 24.The secondary end points were responses of the ACR50 and ACR70 improvement criteria,and the European League Against Rheumatism(EULAR)response criteria.The change from baseline in duration of pain,patient's global assessment,physician's global assessment,tender joint count/index,swollen joint count/index,health assessment questionnaire(HAQ),erythrocyte sedimentation rate(ESR)were also evaluated.The clinical efficacy and safety were analyzed at baseline,6,12 and 24 weeks respectively.Results The ACR response rate was significantly higher in the MTX plus CTX treatment group compared with MTX or CTX group at week 24.The MTX plus CTX group,MTX group and CTX group showed 81%,56% and 35% in ACR20,58%,41% and 12% in ACR50 and 19%,11% and 0 in ACR70,.respectively.At week 24,the proportion of patients achieving the EULAR moderate response in those who received combination treatment were significantly higher than those who received either MTX or CTX.The incidence of adverse events(AEs)was not significantly higher in MTX plus CTX group than MTX or CTX group.Conclusion MTX plus CTX effectively reduces the signs and symptoms of RA and is generally well tolerated by patients without significant increase in the rate of adverse events compared with monotherapy.

Objective To analyze the quality of life of patients with active rheumatoid arthritis (RA) and its relationship with other clinical and functional parameters used for the evaluation of disease activity. Methods The quality of life was assessed in 127 patients with active RA using SF-36 and was compared with non-active RA and the general population. The correlation between the quality of life and the clinical measures of disease, including morning stiffness, pain, fatigue, patient's global assessment (PGA) physician's global assessment , SJC/SJ1, TJC/TJI, DAS28, HAQ were measured. Results The patients with active RA reported significantly decreased scores in all dimensions of SF-36. Fatigue, PGA, physician's global assess-ment, DAS28 and HAQ significantly correlated with the scores in all dimensions of SF-36. Pain was correlated with the scores in all dimensions of SF-36 except RE. TJI was correlated with six dimensions. TJC was correlated with five dimensions. ESR was correlated with three dimensions. Conclusion The quality of life in patients with active RA is significantly declined compared with non-active RA and the general population. Disease activity and functional status of patients with active RA is closely correlated with the quality of life.
