INTRODUCTION: Hydroxychloroquine (HCQ), originally an antimalarial drug, is currently used to treat multiple disorders, especially rheumatic diseases. Given its good efficacy and safety, HCQ is widely administered in pregnant patients. However, the safety profile of HCQ during pregnancy remains controversial due to limited research. In addition, HCQ has been reported to reduce preeclampsia in patients with systemic lupus erythematosus (SLE) and could potentially alleviate the symptom of preeclampsia. However, the clinical profile and molecular mechanism of HCQ in preeclampsia is yet to be fully understood. METHOD: We reviewed the literature on HCQ treatment in pregnancy with rheumatic diseases and preeclamp-sia in PubMed and Web of Science. We also discussed the safety of long-term therapy with HCQ during pregnancy. RESULTS: HCQ mainly modulates autoimmune response through inhibition of lysosomal function, toll-like receptor (TLR) signalling, nicotinamide adenine dinucleotide phosphate-mediated oxidative stress and autophagy. Benefits of HCQ in treating rheumatic diseases, including antiphospholipid syndrome, rheumatoid arthritis and Sjogren's syndrome during pregnancy, has been demonstrated in clinics. In particular, multiple clinical guidelines recommend HCQ as an indispensable therapeutic drug for pregnant patients with SLE. Additionally, it may potentially function in preeclampsia to improve clinical symptoms. CONCLUSION HCQ is effectively used for rheumatic diseases during pregnancy. The benefits of HCQ treatment in rheumatic diseases outweigh the risk of adverse reactions it induces in pregnant women.

Objective To investigate the effect of ganglioside on nerve function in patients with hypertensive cerebral hemorrhage after operation. Methods 90 cases with hypertensive cerebral hemorrhage after operation from March 2014 to March 2016 in our hospital were divided into control group and observation group, the control group was treated with routine treatment, the observation group was given ganglioside nerve cell nutrition therapy, the two groups of patients after treatment of clinical efficacy, neurological function score, ADL score, hematoma, edema were observed.Result The total effective rate(91.11%) in the observation group was significantly higher than that in the control group(66.67%)(P <0.05), the difference was statistically significant.After 7 days and 28 days after treatment, the volume of hematoma and edema in the observation group was significantly decreased, and the control group had obvious advantages compared with the control group ( P <0.05 ).Compared with seventh days and twenty-eighth days after treatment, the NIHSS score and ADL score of the observation group were significantly better than the control group ( P <0.05 ) , the difference was statistically significant.Conclusion The application of the ganglioside in the treatment of hypertensive cerebral hemorrhage can significantly improve the neurological function, improve the quality of life of patients and clinical treatment effect, has good clinical application value.

The aim of this study is to explore the tissue distribution of PEGylated puerarin in acute myocardial ischemia model rats. Healthy male SD rats were randomly divided into two groups (30 each). Both were given PEGylated puerarin at a dose of 488 mg x kg(-1). After 5 min of medication, one group was normal rats, another group with acute myocardial ischemia was established by peritoneal injection of 50 mg x kg(-1) isoprenaline. After administration, the animals were executed at 30, 60, 90, 120, 150 and 180 min, then heart, liver, spleen, lung, kidney were extracted. The content of puerarin in organ tissue was determined by HPLC. The results showed that the AUC of tissue distribution of PEGylated puerarin in normal rats was liver > kidney > heart ≈ spleen > lung > brain. While the AUC of tissue distribution of PEGylated puerarin in acute myocardial ischemia model rats was liver ≈ heart > kidney > lung ≈ spleen > brain. AUC(heart) of PEGylated puerarin in acute myocardial ischemia model rats was 1.7 times than that of the normal rats, and there was significant difference (P < 0.05). Thus, PEGylated puerarin had a good heart-targeting property in early myocardial infarction area, drugs could accumulate in the ischemic myocardium. It provided important information for further study and clinic use of PEGylated puerarin.

Objective To explore the effects of maternal hypercholanemia on the myocardium changes in rat fetus. Methods Thirty clean SD female rats were equally randomized to three groups after mating successfully.From the 13th to 20th day of gestation,group A and B were injected injected with sodium chloride(NS) as control.Total bile acid(TBA) and cardiac troponin I(cTnI) were measured in the maternal and fetal serum on the 21st day when all rats were killed.Fetal cardiac muscle cells were also collected for examination with light microscope and electronic microscope.Results (1)TBA in maternal and fetal serum were(22.32±8.12)μmol/L and(28.84±8.06) μmol/L,respectively in group A,(9.77±3.56)/μmol/L and(9.34±3.54) μmol/L in group B,and (3.60±1.78) μmol/L and(3.95±1.19) μmol/L in group C.Significant differences were found among groups(P<0.01).(2)Fetal death rates were significantly different among the three groups (P<0.05),with 30.11%,16.85%,and 7.05%,respectively.(3)Fetal cTnl were also found significant difference among groups(P<0.01),with(19.98±7.75)ng/ml,(11.41±3.64)ng/ml and(4.38±1.19)ng/ml,respectively.(4)The integrated scores of fetal necrosis area were significantly different in three groups(P<0.05),with 1.92±0.43,1.36±0.37 and 0.44±0.12,respectively.(5)Under electronic microscope,the number density of mitochondria in group A was lower than that in group C(P<0.05)while the average volume of mitochondria was larger in group A (P<0.05).The average volume of mitoehondria in group B was larger than that in group C(P<0.05) while no difference was found with regard to the number density between the two groups.The number density and average volume of myofibril in group A were lower than those in group C(P<0.05).The number density of myofibril in group B was higher than that in group C(P<0.05) while no difference was found with the average volume.(6)Positive correlations were found in maternal TBA,fetal TBA,fetal cTnI and the integrate of fetal necrosis area when comparing every two of the above factors. Conclusions Fetal myocardium is impaired obviously in hypercholanemia rats.The serum level of TBA and cTnI in fetal rats are positively correlated with each other.
