Background: As of 2019, according to the Health Indicators of the Mongolian population, diseases of the digestive system ranked second in terms of morbidity, with gallbladder, biliary tract, and pancreatic diseases accounting for 14.2%, and the proportion of surgeries related to these diseases is high. Aim: Explore the ingredients and recipes of traditional medicine used for gallbladder disease. Materials and Methods: “The four foundations of medicine-Анагаах ухааны дөрвөн үндэс” and their interpretations, and source works were selected, and hermeneutic methodology, comparative method of source studies, historical classification method, and analysis-synthesis method were used. Results: A total of 43 recipes for treating gallstone disease were selected from the source texts. In terms of the method of treatment, all of them were written as hot and cold. The medicine for gallstone heat disease was directly written in “Manag Renchinjunai-Mанаг рэнчинжунай”. The two recipes were explained as new and old in the “Four springs-Рашааны дусал”. Although the contents written in other source books are the same as “The four foundations of medicine-Анагаах ухааны дөрвөн үндэс”, the “The four foundations of medicine-Анагаах ухааны дөрвөн үндэс” are very clearly explained as medicines to be taken, decoctions, and medicines to be given when the effects of heat are delayed. There is no difference in the following books and sutras regarding treatment, food and drink, and events. The method of adding mantras to the national method of Uvdis is not written in other sutras. The medicine for gallstone cold disease was directly written in “Manag Renchinjunai-Mанаг рэнчинжунай”. The amount of medicine in the “Four springs-Рашааны дусал” was carefully calculated. “The four foundations of medicine-Анагаах ухааны дөрвөн үндэс”are astringent, emetic, laxative, stopping the tail of the tail, and cutting off the tail of the disease and replacing it. The method of treating the disease is a method of adding charms to the root, and the “Four springs-Рашааны дусал” are also explained. The food and drink and the event are not written in the Mанаг рэнчинжунай, and there is no difference in other books and scriptures. Conclusion While many recipes for treating gallbladder diseases have been discovered in traditional treatises, the number of recipes and medicines for treating gallbladder heat diseases is greater than the number of medicines for treating gallbladder cold diseases.

Following on our recently developed biphenyl-ATDP non-nucleoside reverse transcriptase inhibitor ZLM-66 (SI = 2019.80, S = 1.9 μg/mL), a series of novel heterocycle-substituted ATDP derivatives with significantly improved selectivity and solubility were identified by replacement of the biphenyl moiety of ZLM-66 with heterocyclic group with lower lipophilicity. Evidently, the representative analog 7wb> in this series exhibited dramatically enhanced selectivity and solubility (SI = 12,497.73, S = 4472 μg/mL) in comparison with ZLM-66 (SI = 2019.80, S = 1.9 μg/mL). This new NNRTI conferred low nanomolar inhibition of wild-type HIV-1 strain and tested mutant strains (K103N, L100I, Y181C, E138K, and K103N + Y181C). The analog also demonstrated favorable safety and pharmacokinetic profiles, as evidenced by its insensitivity to CYP and hERG, lack of mortality and pathological damage, and good oral bioavailability in rats (F = 27.1%). Further development of 7wb> for HIV therapy will be facilitated by this valuable information.

Objective:b> To clarify the values of autotaxin (ATX) in patients with primary biliary cholangitis (PBC) and PBC-related hepatocellular carcinoma (HCC). Methods:b> 179 patients with PBC were selected from prospective cohorts of autoimmune liver diseases at the time of first diagnosis of PBC in Department of Hepatology, the Fifth Medical Center of PLA General Hospital, from January 2016 to January 2018, all patients with PBC received UDCA therapy, primary endpoint was event of HCC, the follow-up period was censored at the date of HCC. The relationship between level of ATX and clinical features in patients with PBC and its potential value in predicting disease progression and PBC-related HCC were analyzed. Results:b> The ATX level in the peripheral blood of patients with PBC was significantly higher than that of alcoholic liver cirrhosis(ALC) (t = 3.278, P = 0.001) and healthy controls(HC) (t = 6.594, P < 0.001), however, when comparing PBC to non-PBC related HCC, no significant difference was found between the groups(t=-0.240, P = 0.811). Consistent with peripheral blood levels, histochemical staining indicated that ATX in the liver of patients with PBC was significantly higher than that of HC (Z=-3.633, P < 0.001) and ALC (Z=-3.283, P < 0.001), and the expression of ATX in PBC with advanced histological stage was significantly higher than PBC with early stage (Z=-2.018, P = 0.034). The baseline ATX level in PBC patients without developing to HCC during follow-up had significant difference to patients with developing to HCC (228.451 ± 124.093 ng/ml vs 301.583 ± 100.512 ng/ml, t = 2.339, P = 0.021). The result in multivariate logistic regression analysis showed that ATX were independent predictors of PBC related HCC(OR 1.245, 95%CI 1.097-1.413). The optimal critical value of peripheral blood ATX level at baseline for predicting HCC was 235.254 ng/ml, with the cut-off value of 0.714 in AUC of the ROC (95% CI was 0.597~ 0.857), sensitivity and specificity were 84.6% and 59.0%, respectively. Conclusion:b> ATX level was significantly higher in PBC patients over controls, and it's concentration was correlated with UDCA efficacy and fibrosis stage. ATX has potential values in predicting disease progression and PBC-related HCC.

Indolylarylsulfones (IASs) are classical HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) with a unique scaffold and possess potent antiviral activity. To address the high cytotoxicity and improve safety profiles of IASs, we introduced various sulfonamide groups linked by alkyl diamine chain to explore the entrance channel of non-nucleoside inhibitors binding pocket. 48 compounds were designed and synthesized to evaluate their anti-HIV-1 activities and reverse transcriptase inhibition activities. Especially, compound R₁₀L₄ was endowed with significant inhibitory activity towards wild-type HIV-1 (EC_50(WT) = 0.007 μmol/L, SI = 30,930) as well as a panel of single-mutant strains exemplified by L100I (EC₅₀ = 0.017 μmol/L, SI = 13,055), E138K (EC₅₀ = 0.017 μmol/L, SI = 13,123) and Y181C (EC₅₀ = 0.045 μmol/L, SI = 4753) which were superior to Nevirapine and Etravirine. Notably, R₁₀L₄ was characterized with significantly reduced cytotoxicity (CC₅₀ = 216.51 μmol/L) and showed no remarkable in vivo toxic effects (acute and subacute toxicity). Moreover, the computer-based docking study was also employed to characterize the binding mode between R₁₀L₄ and HIV-1 RT. Additionally, R₁₀L₄ presented an acceptable pharmacokinetic profile. Collectively, these results deliver precious insights for next optimization and indicate that the sulfonamide IAS derivatives are promising NNRTIs for further development.
