1.Recent advances in drug development targeting bile acids transporters and related disease
Acta Pharmaceutica Sinica 2022;57(12):3576-3586
Bile acids (BAs) are a major component of bile salt, which plays a vital role in the metabolism of lipids in humans. Ninety-five percent of bile acids are recycled by the enterohepatic circulation (EHC), and therefore EHC is essential for bile acid homeostasis. There are four transporters that mediate the transmembrane transport of bile acids, each of which plays an important role in the enterohepatic circulation. Gene defects in bile acid transporters can lead to disorders of the enterohepatic circulation, ultimately leading to clinical phenotypes such as metabolic diseases and even death. Bile transporter expression is altered in patients with various metabolic disease states, suggesting that disruption of bile acid transporters may be a pivotal pathological mechanism for the development of metabolism diseases. Thus, many drugs targeting bile acid transporters are being developed. We provide a concise overview of the progress of bile acid transporters research, discuss the relationship between different bile acid transporters and disease development, and summarize the current progress in drug development targeting bile acid transporters.

Abstract: A new selaginellin derivative named as selaginellin S (1) was isolated from the whole plants of Selaginella pulvinata (Hook. et Grev.) Maxim. (Selaginellaceae), together with a known one (selaginellin M, 2). Compounds 1 and 2 were separated and purified by silica gel and Sephadex LH-20 column chromatography. Their structures were determined on the basis of extensive spectroscopic analysis including IR, MS, 1D and 2D NMR experiments, as well as ECD calculations. Compound 1 is a key intermidiant in the biosynthesis pathway of selaginellins. Compound 2 is first reported in this plant.

Objective To study intermediate and long term efficacy of uterine arterial embolization (UAE)with sodium alginate microspheres(KMG)at diameters 500-700μm in treatment of diffuse adenomyosis.Methods Totally 40 patients with standard difluse adenomyosis were enrolled and treated with UAE.KMG at diameters 500-700 μm for vascular embolization were used to embolize the arteries.The degree of dysmenorrhea,amount of menorrhea and uterine volume,as well as the level of serum CA125,follicle stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2)were investigated before andafter UAE.Results The follow up rates were 100%(40/40),100%(40/40),80%(32/40),68%(27/40),58%(23/40)after uterine arterial UAE 12,24,36,48 and 60 months respectively.The early,intermediate and long-term effective rates were 90%(36/40),88%(28/32),83%(19/23).The degree of dysmenorrhea,the amount of menorrhea and the uterine volume,as well as serum CA125 all decreased significantly 3 mouths after UAE at varying degrees(P<0.05).Compared with other follow-up time,thedegree of dysmenorrhea and the amount of menorrhea declined to their lowest point at 6 month after UAE (P<0.01).Paralleled with the decrease of volume of uterine,serum CA125 also decreased significantly and reached the lowest level 12 months later compared with other follow-up times(P<0.01).Even at the 12th month after UAE serum CA125was not normal and FSH,LH and E2 did not change all the times after UAE(P>0.05).No recurrence was found during the 60 months after UAE.Condusion KMG used in UAE at diameters 500-700 μm has good intermediate and long term effectiveness in treatment of diffuse adenomyosis with no side effects.

Objective To evaluate the effects of Xuebijing injection on inflammatory mediators of patients with severe acute pancreatitis. Methods Using double blind method, 80 cases with severe acute pancreatitis were randomly divided into two groups, with 40 cases in each group. The control group was treated with conventional therapy such as: fasting, fluid replacement, acid inhibition and anti-infection, combined with the continuing injection with the growth hormone release inhibiting 6 mg, ulinastatin 200000u for 7 days. Based on the control group's treatment, the other group was added with Xuebijing injection 50 ml, twice a day for 7days. The plasma levels of prostaglandin Ⅰ2 (PGI2), thromboxane A2 (TXA2), tumor necrosis factor α (TNFα),interleukin-1,6,8 (IL-1,6,8) were compared before and after the treatment in each group and between two groups.Results Compared with the control group, Xuebijing injection group had marked effects on modulating the levels of inflammatory mediators. The levels of PGI2 and PGI2/TXA2 were increased significantly and the levels ofTXA2, TNF2, IL-1,6 and 8 were deceased(P<0.05)sharply after the treatment. Conclusion Combined with conventional western medicine therapy, Xuebijing injection has the effects of inhibiting and controlling the release of inflammatory mediators on patients with severe acute pancreatitis.

The changes of bioactive constituents were analyzed for Puhuang-Wulingzhi before and after compatibility and the antiplatelet and antithrombin activitives were evaluated in order to elucidate the scientific and reasonable of Puhuang-Wulingzhi compatibility. UPLC-QTOF-MA-Markerlynx, principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis were used for data analysis and tracking changes of chemical composition during the decocting process. In vitro platelet aggregation induced by ADP, thrombin time(TT) and prothrombin time (PT) were investigated for Puhuang-Wulingzhi before and after compatibility. The results showed that significant differences were found between the mixed decoction and codecoction of Wulingzhi and Puhuang. Five compounds changed obviously were identified as typhaneoside, naringenin, isorhamnetin-3-O-ruinoside, quercetin-3-O-neohesperidoside, kaempferol-3-O-neohesperidoside. The codecoction, comparing with the single decoction, was more significant in antiplatelet aggregation and could prolong thrombin time. In the same crude drug dose, the thrombin time (TT) elongation were greater. These data could provide references for elucidation of bioactive components for this herb pair.

OBJECTIVE:
The study was to evaluate the quality of life in patients with fungal rhino-sinusitis(FRS) and to investigate the relationship between different subjective tests.objective measures and that between subjective tests and objective measures.
METHOD:
Quantitative data of 18 preoperative recruits with FRS were collected by using sino-nasal outcome test-20 (SNOT-20) and then the SNOT-20 items were categorized into five domains, a visual analogue scale (VAS). Lund-Kennedy endoscopy staging system and the Lund-Mackay CT staging system. Correlation among these data was analyzed.
RESULT:
The six highest score items in SNOT-20 were Facial pain/pressure, Thick nasal discharge, Need to blow nose, Sneezing, Fatigue, and Frustrated/restless/irritable. The total SNOT-20 score was not correlated with the other objective or subjective tests(P > 0.05). However, there was significant correlation between SNOT-20 nasal symptom domain and Lund-Mackay T score( r = 0.605, P < 0.01), as well as between SNOT-20 sleep related symptom domain and VAS (r = 0.605, P = 0.008). Significant correlation was found between the Lund-Mackay CT staging and the VAS (r = 0.6150, P < 0.01), as well as between the Lund-Mackay CT staging and the Lund-Kennedy endoscopy staging (r = 0.5001 P < 0.05). There was no significant correlation between Lund Kennedy endoscopy staging and the patient-based questionnaires (P > 0.05).
CONCLUSION
The objective measures were correlated well with each other and CT staging had significant correlation with the SNOT-20 nasal symptom domain and VAS. There was also significant correlation between SNOT-20 sleep related symptom domain and VAS.

Objective To observe the influence of simulated microgravity on rat islet. Methods Isolated islet were assigned to flask-culture or bioreactor-culture. Gross structure and ultrastructure of islet were observed by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Results Islets ultrastructure on 7th day in bioreactor closely resembled fresh islets,with well-formed secretory granules and abundant mitochondria. SEM showed under microgravity islets communicating each other with cavity-like areas. Conclusions The ultrastructure of islets cultured under microgravity closely resembled fresh islets.
