Objective To analyze the distribution and drug resistance patterns of pathogenic bacteria in bile and blood cultures obtained from patients with biliary stones accompanied by acute biliary tract infection,to evaluate the clinical appropriate-ness of antibiotic use based on drug sensitivity results,and to provide evidence for empirical antibiotic treatment in such patients.Methods The clinical data of 161 patients with biliary calculi complicated by acute biliary tract infection who were admitted to the First People's Hospital of Neijiang from 2017 to 2023 were retrospectively analyzed.The results of microbial culture,drug sensitivity analysis,and patient characteristics were assessed to evaluate the appropriateness of clinical antimicrobial therapy.Results Among the 161 patients with positive cultures,212 strains of pathogenic bacteria were detected.The predominant patho-gens were Escherichia coli,Klebsiella pneumoniae subspecies,and Enterococcus faecium.Age and underlying diseases significantly affected the distribution of Escherichia coli and Klebsiella pneumoniae subspecies.Within the gram-negative bacterial group,Esche-richia coli and Klebsiella pneumoniae subspecies exhibited higher drug resistance to commonly used broad-spectrum penicillin,third-generation cephalosporin and quinolones but lower resistance rates to piperacillin and tazobactam;furthermore,elderly indi-viduals aged ≥65 years showed higher resistance rates to ceftriaxone than those under age 65 while people with drug exposure history had higher ceftazidime resistance rates that were statistically significant.In contrast to Enterococcus faecalis which displayed low antimicrobial resistance rates for most drugs tested in this study,Enterococcus faecium demonstrated high levels of antibiotic resistance;however,both Enterococcus faecalis and Enterococcus faecium exhibited zero-resistance rates against vancomycin and tigecycline although this may be attributed to their small sample size in our study cohort.Finally,we found that empirical anti-in-fective drugs,as well as target anti-infective drugs,were not prescribed rationally among these patients due mainly to inappropriate combinations of antibiotics or incorrect dosages.Conclusions The predominant pathogens in patients with acute biliary tract infection are gram-negative bacteria,Gram-positive bacteria,and fungi;however,the potential involvement of anaerobic bacteria should not be overlooked.Vancomycin exhibits sensitivity against gram-positive bacteria,yet the overall rationality of antibiotic usage remains suboptimal.Enhanced clinical testing for pathogenic microorganisms is imperative in the management of biliary stones accompanied by acute biliary tract infection.In contrast,clinical pharmacists should provide comprehensive training on anti-infective drugs to clinicians to facilitate their judicious selection of antibiotics based on drug sensitivity results and prevent the e-mergence of multidrug-resistant bacteria.

OBJECTIVE To op timize the i ntegrated technology of producing area processing and decoction pieces processing of Curcuma longa (hereinafter refer to “integrated technology ”). METHODS The content of ethanol-soluble extract in C. longa was determined by hot leaching method ;the contents of curcumin ,demethoxycurcumin and bisdemethoxycurcumin were determined by high performance liquid chromatography. On the basis of identification of producing area processing technology , Using overall desirability (OD) value of the contents of ethanol-soluble extract , curcumin, demethoxycurcumin and bisdemethoxycurcumin as evaluation indexes ,moisture content ,slice thickness and drying temperature as factors ,the integrated technology of C. longa was optimized by single factor tests combined with central composite design-response surface method ,and the validation tests were conducted. At the same time ,prepared product was compared with traditional decoction pieces prepared according to 2020 edition of Chinese Pharmacopoeia (part Ⅰ). RESULTS The best integrated technology was that the fresh C. longa was boiled in boiling water for 5 min,dried at 50 ℃ to 40% water content ,cut into 2 mm thin slices ,and dried at 50 ℃ until moisture content not exceeding 15.0%. After validation ,The deviation between the average OD value (0.811 3,RSD=2.13%) and the predicted value (0.848 1)of the contents of ethanol-soluble extract ,curcumin,demethoxycurcumin and bisdemethoxycurcumin was 4.34%. OD value of the contents of ethanol-soluble extract ,curcumin,demethoxycurcumin and bisdemethoxycurcumin in decoction pieces prepared by integrated technology were all higher than those prepared by traditional technology. CONCLUSIONS The process optimized in this study is simple ,stable and feasible.

Objective To discuss the clinical therapeutic effect of Kangmin xiaoyan lotion combined with levocetirizine hydrochloride in the treatment of facial recurrent dermatitis. Methods Eighty cases of facial recurrent dermatitis were randomly divided into treatment group and control group,40 cases in each group.The treatment group was given Kangmin xiaoyan lotion with wet compression for 20 min in the morning and evening,and levocetirizine hydrochloride 10 mL orally once daily;the control group was only given levocetirizine hydrochloride orally once daily.One month later,the symptoms and signs of skin lesions and adverse reactions in each group were observed. Results One month after the treatment,the scores of symptoms and signs were significantly decreased in the two groups (P<0.05).After the treatment,the scores were significantly different between the two groups (P<0.05).Clinical efficacy of the treatment group and control group was 92.5% and 65.0%,with significant difference(P<0.05). Conclusion Kangmin xiaoyan lotion can be effective in the treatment of facial recurrent dermatitis,and it is worthy of clinical application.

High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.
