1.Mechanisms of Diabetogenic Action of Statins
China Pharmacist 2017;20(2):337-339
Objective:To alarm the effect of statins on blood glucose, and provide evidence for the rational use of statins in clin-ics. Methods:The recent articles on the effects and potential mechanisms of diabetogenic action of statins were reviewed and summa-rized. Results and Conclusion:Stains, especially lipophilic stains, could increase blood glucose via multiple pathways to induce dia-betes. The potential mechanisms included inhibiting L-type calcium channel, increasing the uptake of plasma-derived LDL-C, inhibi-ting synthesis of ATP and Coenzyme Q10, inhibiting the expression of glucose transporter 4 and inducingβ-cell inflammation, oxidation and apoptosis. Blood glucose should be monitored and adjusted timely when statins are used in clinics.

Objective To study the effect of Dachengqi decoction on expression of triggering receptor on myeloid cell 1(TREM-1)in septic rats in order to further provide a theoretical basis concerning the mechanism of this decoction for treatment of sepsis. Methods 100 male Sprague-Dawley(SD)rats were randomly divided into five groups:normal control,sham operation,sepsis model,low-dose and high-dose Dachengqi decoction groups (each,n=20). The sepsis models were reproduced by cecal ligated perforation(CLP). The low-dose and high-dose Dachengqi decoction groups were lavaged separately by low dose(5 mL/kg)and normal dose(10 mL/kg)Dachengqi decoction at 2 hours before CLP and after CLP twice per day(interval 8 hours),and the other three groups were lavaged with 10 mL/kg normal saline. Five rats in each group were killed randomly at the time points of 6,12,24,48 hours after CLP;the abdominal aorta blood and the liver tissue were collected. The plasma levels of TREM-1,interleukin-6 (IL-6),tumor necrosis factor-α(TNF-α)were tested by enzyme linked immunosorbent assay(ELISA). The expression level of TREM-1 mRNA in the liver was measured by reverse transcription - polymerase chain reaction (RT-PCR). Results Compared with normal control group and sham operation group, the plasma levels of TREM-1, IL-6, TNF-α and the expression of liver TREM-1 mRNA were increased significantly in model group. Compared with model group,the above indexes in low-dose and high-dose Dachengqi decoction groups were reduced obviously,the changes being more marked in the high-dose group;the levels of TREM-1,IL-6 at 6 hours after operation and the levels of TNF-αand TREM-1 mRNA at 24 hours after operation in high-dose group were lower than those of low-dose group〔6 hours TREM-1(ng/L):179.19±4.43 vs. 213.86±2.84,6 hours IL-6 (ng/L):136.80±7.70 vs. 162.90±3.87;24 hours TNF-α(ng/L):71.61±5.07 vs. 108.53±6.29,24 hours TREM-1 mRNA:24.33±3.16 vs. 27.22±3.34,all P<0.05〕. Conclusion The partial mechanism of the efficacy of Dachengqi decoction for treatment of sepsis was probably related to the inhibition of TREM-1 expression.

ObjectiveTo observe the effects of six stagnations elimination therapy on the content of typeⅠ, typeⅢ collagens and matrix metalloproteinase-9 (MMP-9) expression in atherosclerotic mice with vulnerable plaques, to discuss the possible mechanisms of this therapy in stabilizing vulnerable plaques.Methods The ApoE knockout mice were fed on high-fat diets, which built the vulnerable plaques model. Five groups were established, including normal group, model group, high-dose group, low-dose group, and simvastatin group, with 10 mice in each group. Dose groups were given drug intervention, while normal group and model group were given in the same amount of saline. After 12 weeks of drug intervention, the mice were put to death. TypeⅠ and typeⅢcollagens were observed using picric acid-Sirius red staining method. The expression of MMP-9 was detected by immunohistochemical method.ResultsCompared with normal group, vulnerable plaques formed more easily in model group.Compared with model group, typeⅠ collagen increased in high-does and low-dose groups, while typeⅢ collagen, the ratio of typeⅢ andⅠ collagens, and the expression of MMP-9 decreased (P<0.01).ConclusionSix stagnations elimination therapy could stabilize vulnerable plaques. Regulating typeⅠ andⅢ collagens content and inhibiting the expression of MMP-9 may be one of its possible mechanisms.

Hypokalemia is a common clinical symptom. It is quite important to clarify the cause of hypokalemia. Autoimmune thyroid disease and primary Sjogren syndrome ( pSS ) have a common genetic predisposition. The coexistence of both diseases is frequent. Renal tubular acidosis ( RTA) is one of the causes of hypokalemia, which can be primary and secondary to other diseases in etiology. Primary RTA is more common in children. As for adults, RTA is often secondary to pSS. In this paper, we reported a case of hypokalemia caused by Hashimoto’s thyroiditis associated with primary Sjogren’s syndrome and renal tubular acidosis in order to call attention to the special cause and treatment of hypokalemia.
7. Research progress on the treatment of non-small cell lung cancer with nivolumab
Chinese Journal of Clinical Oncology 2020;47(6):304-308
Lung cancer is the leading cause of cancer death and non-small cell lung cancer (NSCLC) accounts for >85% of all cancer deaths. Although chemotherapy and targeted therapy have improved clinical outcomes, prognosis remains poor. With the development of immunotherapy, the treatment strategy for patients with NSCLC has changed. Nivolumab, a human immunoglobulin G4 monoclonal antibody, was the first programmed cell death protein-1 (PD-1) inhibitor drug to be approved for treating advanced NSCLC and has become the primary drug for treating advanced NSCLC. However, there remains a lack of clinical biomarkers to predict the efficacy of nivolumab. In this review, we discuss the progress of therapeutic mechanisms, pharmacokinetics, pharmacology, clinical trials of monotherapy and combined therapy, adverse events, and predictive biomarkers.
