OBJECTIVE To investigate the effects of peiminine B （PEI） on Streptococcus pneumoniae （SP）-induced alveolar epithelial cell injury by regulating the Ras-related C3 botulinum toxin substrate 1 in nucleus accumbens （Rac1）/protein kinase B （Akt）/nuclear factor κB （NF-κB） signaling pathway. METHODS Human alveolar epithelial cells （HPAEpiC） were taken and randomly divided into the Control group， SP group （1×108 cfu/mL SP bacterial solution）， low-， medium-， and high-concentration PEI groups （1×108 cfu/mL SP bacterial solution+0.05， 0.10， 0.20 mmol/L PEI）， and high-concentration PEI+Akt activator group （P-H+SC79 group， 1×108 cfu/mL SP bacterial solution+0.20 mmol/L PEI+10 μmol/L SC79）. Except for the Control group， the other groups of cells were treated with SP bacterial solution and/or corresponding drug solution. After 24 h of treatment， the levels of inflammatory factors （interleukin-6， -18， -1β） in the supernatant solution， the contents of oxidative stress indexes [lactate dehydrogenase （LDH）， reactive oxygen species （ROS） and superoxide dismutase （SOD）]， apoptosis rate， as well as the expressions of proliferation/apoptosis-related proteins [cyclin-dependent kinase 1 （CDK1）， B cell lymphoma-2 related X protein （Bax）] and pathway-related proteins （Rac1， Akt， phosphorylated Akt， NF-κB and phosphorylated NF-κB） were detected in each group. RESULTS Compared with the Control group， the levels of inflammatory factors in supernatant solution， LDH and ROS contents， apoptosis rate， the protein expressions of Bax and Rac1 and the phosphorylation levels of Akt and NF-κB in the SP group were significantly increased or up-regulated， while SOD content and the protein expression of CDK1 were significantly decreased or down-regulated （P＜0.05）. Compared with the SP group， the above indexes in PEI groups were significantly improved in a concentration-dependent manner （P＜0.05）. SC79 could significantly reverse the improvement effect of the high concentration of PEI （P＜0.05）. CONCLUSIONS PEI can alleviate SP-induced inflammation and oxidative stress damage of alveolar epithelial cells and inhibit apoptosis， which may be achieved by inhibiting Rac1/Akt/NF-κB signaling pathway.

OBJECTIVES: To investigate the synergistic inhibitory effects of AKBA and doxorubicin on malignant phenotype of triple-negative breast cancer (TNBC) MDA-MB-231 cells. METHODS: CCK-8 assay was used to determine the 48-h IC₅₀ of AKBA and doxorubicin in MDA-MB-231 cells, and SynergyFinder was employed to calculate the synergistic index and the optimal concentrations of the two agents. MDA-MB-231 cells treated with AKBA (22.5 μmol/L), doxorubicin (0.84 μmol/L) or their combination were examined for changes in cell proliferation, migration, invasion and apoptosis using Transwell migration, scratch assay, clone generation, RT-qPCR and Western blotting. Network pharmacology analysis was conducted to identify the downstream targets of AKBA in TNBC. In nude mouse models bearing subcutaneous MDA-MB-231 cell xenografts, the effects of normal saline, AKBA (50 mg/kg), doxorubicin (2.5 mg/kg), and AKBA combined with doxorubicin on xenograft growth and histopathology were observed. RESULTS: The IC₅₀ of AKBA and doxorubicin in MDA-MB-231 cells at 48 h was 45.15±0.97 μmol/L and 0.42±0.99 μmol/L, respectively. SynergyFinder confirmed the synergistic effect of AKBA and ADR with a ZIP>10. The combined treatment with AKBA and doxorubicin significantly inhibited the proliferation, migration and invasion, promoted apoptosis of MDA-MB-231 cells, and effectively suppressed xenograft growth in nude mice. Network pharmacology analysis predicted that AKBA affects the progression of TNBC through its downstream target AKBA. CONCLUSIONS AKBA combined with doxorubicin inhibits proliferation, migration and invasion, promotes apoptosis of MDA-MB-231 cells and suppresses MDA-MB-231 cell xenograft growth in nude mice. The combined use of AKBA can attenuate the toxic effects of doxorubicin in nude mice.

In this study, different functional layer formulations and process parameters were used to prepare the levomilnacipran hydrochloride sustained-release capsules, the influence of functional layer formulation and process factors on dose dumping was studied by comparing their release curves in 40% ethanol; and the risk of dose dumping of the self-developed drug was evaluated by the similar factors of the release curve of the self-developed drug and the reference drug.The results showed that as the coating weight increased, the degree of dose dumping decreased; when the concentration of ethanol in the coating liquid solvent was less than 80%, the dose dumping increased; as the atomization pressure and maturation time increase, the dose dumping became more serious. In 0% ethanol (purified water), 5% ethanol, 20% ethanol and 40% ethanol media, the self-developed and reference preparations had the same degree of dose dumping within the specified time, and rotation speed had no significant effect on the release of metformin in vitro. In summary, formulation factors such as coating weight gain, ethanol concentration in the coating solution solvent, and process factors such as atomization pressure and curing time have a serious impact on the dose dumping of sustained-release capsules.Under the optimal functional layer formulation and process, special attention should be paid to the control of risk of self-developed dose dumping.

OBJECTIVE: To investigate the therapeutic effect of nasal continuous positive airways pressure (nCPAP) combined with antireflux medicine on obstructive sleep apnea hypopnea syndrome (OSAHS) with gastroesophageal reflux (GER). METHOD: Sixty patients with moderate to severe OSAHS with GER were simultaneously received PSG and esophageal pH monitoring and randomly divided into control group and treatment group with each group 30 patients. The control group were simply received nCPAP for every night. The treatment group were received the same treatment and combined antireflux medicine, with esomeprazole 40 mg/d and mosapride citrate 5 mg, 3 times a day,oral. Both the groups symptomatic status of OSAHS and GER were observed on the third day and the 14th day during therapy, and then the same tests above were repeated on the 14th day. RESULT: Compared with the control group, the symptomatic improvement rate of OSAHS on the third day and 14th day during therapy,the symptomatic improvement rate of GER on the third day during therapy were increased with statistical significance in the treatment group (P<0.05), however, the difference of symptomatic improvement rate of GER between the two groups on the 14th day during therapy did not have statistical significance (P>0.05). Compared with those of the control group on the 14th therapeutic night, AHI, LSaO2, the percentage of time with pH<4, the longest reflux duration,reflux episodes and DeMeester scoring did not have statistical significance in the treatment group (P>0.05). CONCLUSION nCPAP is the most effective method for patients suffering OSAHS associated with GER, but nCPAP used in conjunction with anti-reflux drugs do not improve efficacy.
