At the present,systemic lupus erythematosus is a heterogeneous disease in which diagnosis,especially early diagnosis,is always rather difficult.Because of this,the systems of classification criteria for clinical diagnosis,which include recommendations of the American college of rheumatology and the systemic lupus international collaborating clinics,have been utilized since 1971.However,there is still no single biomarker that is pathognomonic for the disease.Currently,the diagnosis still requiresold-fashioned clinical acumen with the assistance of standardized clinical and laboratory criteria.In the light of the commentary,future research may lead us to define subtypes of lupus from a genomic and proteomic standpoint.

OBJECTIVE:To investigate the effects of Maiqi jiangtang pill combined with insulin on related indicators in mater-nal gestational diabetes. METHODS:135 GDM women were randomly divided into control group (69 cases) and observation group(66 cases). Control group was given diet controlling and exercise therapy,Novolin R insulin biosynthesis and protamine syn-thetic human insulin were injected before meals and bedtime from 4-6 units with the ratio of 4∶2∶3∶1,and decided whether to ad-just the insulin dose based on the blood glucose monitoring results(increase or decrease 2-4 units each times);observation group was additionally given 6 g Maiqi jiangtang pill,4 times a day. The treatment course for both groups was 15 d. Fasting plasma glu-cose(FPG),2 h postprandial glucose(2 h PG),glycated hemoglobin(HbA1c),body mass index(BMI),maternal pregnancy out-comes(preeclampsia,preterm labor,puerperal infection,postpartum hemorrhage,neonatal asphyxia,low-weight children and noc-turnal hypoglycemia)and incidence of adverse reactions in 2 groups were observed. RESULTS:FPG,2 h PG,HbA1c,BMI,pre-eclampsia,preterm labor,low-weight children,neonatal asphyxia and nocturnal hypoglycemia in observation group were signifi-cantly lower than control group,the differences were statistically significant(P<0.05);there were no significant differences in the puerperal infection and postpartum hemorrhage between 2 groups (P>0.05). And there were obvious adverse reactions between 2 groups during treatment. CONCLUSIONS:Maiqi jiangtang pill combined with insulin can effectively reduce the blood glucose of GDM women,with good safety.

Methods: Papers on the research of HUA prevention and treatment with medicine-food homology from December 15, 2002 to August 10, 2024 were screened and collected through China National Knowledge Infrastructure (CNKI), PubMed, ScienceDirect, and Google Scholar. Subsequently, the impact of these medications and their extracts, as well as the active compounds on HUA were assessed. Results: A total of 148 relevant papers were collected, including 43 kinds of Chinese medicines and 61 active compounds, all of which have anti-HUA activity. Among them, 41 kinds of Chinese medicines could inhibit the activity of xanthine oxidase, thus leading to the inhibition of uric acid production; and 22 kinds of Chinese medicines could facilitate uric acid excretion, while 15 kinds of Chinese medicines could reduce the inflammation levels in the body and promoting renal protection. Notably, polyphenols and flavonoids are the key active components for the uric acid-lowering effects. Conclusion This study systematically summarized and analyzed the uric acid-lowering effects and mechanisms of Chinese medicines with medicine-food homology, laying a foundation for their development as HUA agents.

Phased array transducers are very attractive because the beam generated by the arrays can be electronically focused and steered. The present work characterizes far-field 2D properties of phased array system by functions that are deduced from rectangle source, rectangle line array and phased array based on point source. Results are presented for the distribution of ultrasound intensity on plane xoz and on x-axis by simulation using numerical calculation. It is shown that the shape of response of rectangle line array is modulated by the single array element. It is also demonstrated that the delay time of phased array is the key to steer the beam, sacrificing the value of main lobe and increasing the number of side lobes.
