Objective To evaluate the in vitro antifungal activity of Cinnamaldehyde in combination with Voriconazole (VRC) against clinically isolated Aspergillus fumigatus strains. Methods According to the Clinical and Laboratory Stan?dards Institute (CLSI) M38-A2 document,the minimal inhibitory concentrations (MIC) of Cinnamaldehyde and VRC alone or in combination against 42 clinical Aspergillus fumigatus isolates were determined by both microdillution method and check?board method respectively. The MIC50, MIC90, MICG and MICs distribution were compared between single drug and both in combination. The concentration-accumulative curve was drawn and fractional inhibitory concentration index (FICI) was cal?culated to evaluate the interaction between two test agents. Results The values of MIC50, MIC90 and MICG were significant?ly decreased (P<0.001) when combination of the two drugs than those of their single use, with their MIC distribution concen?tration-accumulative curves shifted to the left. The value of FICI of Cinnamaldehye-VRC combination ranged from 0.187 5 to 1.5. Sixteen strains (38.10%) of them showed the synergistic effect, 19 strains (45.23%) showed additive effect, and 7 strains (16.67%) showed an unrelated effect, and no antagonist effect on tested Aspergillus fumigatus strains in vitro. Conclu?sion Cinnamaldehye in combination with VRC mainly shows a combined synergic and additive inhibitory effect on Asper?gillus fumigatus isolates, and this combination appears to be more active against the test strains, which are less susceptible to voriconazole.

This study was aimed to investigate the influence on component content indexes,which included chlorogenic acid and luteolin of honeysuckle by the absorption of chemical insecticide thiamethoxam.High-performance liquid chromatography (HPLC) method was used in the analysis of content determination of component content indexes of honeysuckle samples by different concentrations of thiamethoxam.SPSS was used in the statistical analysis.The results showed that compared to samples from the blank control group,the content of chlorogenic acid had the increasing tendency in the honeysuckle groups with different concentrations of thiamethoxam.However,there was no significant difference among different experiment groups.There was no significant difference on luteolin among honeysuckle groups with different concentrations of thiamethoxam and the blank control group.It was concluded that at the recommended dose and high-powered dose of thiamethoxam,there was some influence on the content of chlorogenic acid.However,there was no significant effect on the content of luteoloside.And the quality scores of both contents were within the range defined in the Chinese Pharmacopoeia(2010 edition).

Aim Toinvestigatewhetherexposureto Sanguinarine (SAN ) can inhibit cell proliferation in human mammary adenocarcinoma cells (MCF-7 ) and thepossiblemechanism.Methods WeexposedMCF-7 to anticancer compound SAN,cell viability was as-sessed by using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT ) reduction assay. ROS was measured using confocal microscopy,expres-sion of caspase-3 ,caspase-8 and caspase-9 were calcu-latedusingchemiluminescencemethod.Results SAN remarkably inhibited growth of human mammary adeno-carcinoma MCF-7 cells by decreasing cell proliferation. ROS release and caspase-3,caspase-8,caspase-9 ex-pression were stimulated by SAN in MCF-7 ,and these changes were abolished by the antioxidant,N-acetyl-cysteine(NAC).Conclusion Regulationofcaspases expression and release from MCF-7 cells are possibly e-voked by SAN through reactive oxygen species.

Background:Gastroesophageal reflux disease(GERD)is a common digestive disorder,but its underlying causes are still unclear.Patients with GERD often experience anxiety,depression,and ineffective esophageal motility.However,there have been limited studies on the relationship between anxiety/depression and esophageal motility.Aims:To investigate the mental state of patients with different subtypes of GERD and explore its correlation with esophageal motility.Methods:From September 2018 to June 2022,a total of 96 outpatients presenting typical acid reflux and heartburn symptoms with a GerdQ score≥10 were enrolled at Jincheng People's Hospital.They were divided into two groups based on gastroscopy findings:non-erosive reflux disease(NERD)group(77 cases)and reflux esophagitis(RE)group(19 cases).General data,clinical symptoms,anxiety/depression scores,and high-resolution esophageal manometry results were compared between the two groups using t-test,chi-square test,and Spearman correlation analysis.Results:There was a statistically significant difference between the NERD group and RE group(P<0.05),with more females in the NERD group.The self-rating anxiety scale(SAS)scores were significantly higher in the NERD group[44.00(29.00-58.00)]compared to the RE group[23.00(20.00-29.38)],indicating a greater presence of anxiety in the NERD group than in the RE group;this difference was statistically significant(P<0.01).However,there was no significant difference in self-rating depression scale(SDS),Hamilton anxiety scale(HAMA),or Hamilton depression scale(HAMD)scores between the two groups.Furthermore,a negative correlation was observed between distal contractile integral(DCI)values and SAS scores among GERD patients(P<0.05).Additionally,a small negative correlation existed between DCI values and SDS,HAMA,and HAMD(P>0.05).Conclusions:The NERD group exhibits a more pronounced anxiety state compared to the RE group.Furthermore,there exists a negative correlation between the anxiety state of GERD patients and DCI,suggesting that anxiety may influence esophageal motility involvement in the pathogenesis of GERD.

Objective: To evaluate the efficacy and safety of laparoscopic surgery in the treatment of gallstones and common bile duct stones. Methods: Eighty-seven patients with gallstones complicated with common bile duct stones who underwent concurrent laparoscopic surgery at Zhoushan Hospital from December 2015 to December 2017 were enrolled.The patients were divided into A group and B group according to the digital table.A group(38 cases) underwent laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE), and B group(49 cases) underwent endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) combined with laparoscopic cholecystectomy (LC). The curative effect of the two groups was observed.The operation time, the success rate of the operation and the rate of laparotomy were recorded in the two groups.The corresponding hospitalization time and cost were compared.The safety of the two different procedures was compared after surgery, and the complications of the two groups were recorded. Results: In A group, the average diameter of common bile duct stones was (1.02±0.25)cm, the average diameter of common bile duct diameter was (1.15±0.25)cm.In B group, the mean diameter of common bile duct stones was (0.99±0.26)cm, and the average diameter of common bile duct was (1.13±0.26) cm.The differences between the two groups were not statistically significant (t=0.513, 0.437, 0.367, P=2.083, 1.533, 1.095). The successful operation rate of A group was 92.11%(35/38), which in B group was 91.84%(45/49), the difference was not statistically significant between the two groups(χ²=0.006, P=0.974). The incidence rate of complications in B group was 20.41%, which was significantly higher than that in A group, the difference was statistically significant(χ²=3.654, P=0.019). The hospitalization time, hospitalization expenses in A group were (10.6±2.6)d, (26 649.8±3 478.6)CNY, respectively, which were significantly better than those in B group (t=21.971, 17.168, all P<0.05). Conclusion The efficacy of LC combined with LCBDE for patients with gallstones complicated with common bile duct stones is better than ERCP/EST combined with LC surgery, and the safety of the former is higher than the latter.

Irinotecan is an anticancer topoisomerase I inhibitor that acts as a prodrug of the active metabolite, SN-38. Unfortunately, the limited utility of irinotecan is attributed to its pH-dependent stability, short half-life and dose-limiting toxicity. To address this problem, a novel trivalent PEGylated prodrug (PEG-[Irinotecan]₃) has been synthesized and its full-profile pharmacokinetics, antitumor activity and toxicity compared with those of irinotecan. The results show that after intravenous administration to rats, PEG-[Irinotecan]₃ undergoes stepwise loss of irinotecan to form PEG-[Irinotecan]_3‒x (x = 1,2) and PEG-[linker] during which time the released irinotecan undergoes conversion to SN-38. As compared with conventional irinotecan, PEG-[Irinotecan]₃ displays extended release of irinotecan and efficient formation of SN-38 with significantly improved AUC and half-life. In a colorectal cancer-bearing model in nude mice, the tumor concentrations of irinotecan and SN-38 produced by PEG-[Irinotecan]₃ were respectively 86.2 and 2293 times higher at 48 h than produced by irinotecan. In summary, PEG-[Irinotecan]₃ displays superior pharmacokinetic characteristics and antitumor activity with lower toxicity than irinotecan. This supports the view that PEG-[Irinotecan]₃ is a superior anticancer drug to irinotecan and it has entered the phase II trial stage.

A simple, fast, and visual method for detecting antibodies against peste des petits ruminants virus (PPRV) using colloidal gold strips was developed. In this study, the pET-32a-N was transformed into Escherichia coli Rosetta (DE3) for expression. Hybridoma cell lines were generated by fusing SP2/0 myeloma cells with splenocytes from immunized mice with the expressed and purified N protein of PPRV. The PPRV N protein was labeled with colloidal gold particles as the gold-labeled antigen. The N protein served as the gold standard antigen and as the test (T) line-coated antigen, while the monoclonal antibody served as the quality control (C) line-coated antibody to assemble the colloidal gold immunochromatographic test strips for detecting antibodies against the N protein of PPRV. Hybridoma cell line designated as 1F1 was able to stably secrete the monoclonal antibody against the N protein of PPRV. The titer of 1F1 monoclonal antibody in ascites was 1:128 000 determined by indirect enzyme-linked immunosorbent assays (ELISA), and the immunoglobulin subtype of the monoclonal antibody was IgG1, with kappa chain. The obtained monoclonal antibody was able to specifically recognize the N protein of PPRV, as shown by Western blotting and indirect immunofluorescent assay (IFA). The developed colloidal gold test strip method was able to detect PPRV antibodies specifically, and there was no difference between different batches of the test strips. Testing of a total of 122 clinical sera showed that the compliance rate of the test strip with ELISA test was 97.6%.The test strip assay developed in this study has good specificity, reproducibility, and sensitivity, and it can be used for the rapid detection of PPRV antibodies.
