Objective To explore the identification method,pathogenesis,clinical characteristics and individualized pharmacotherapy of asymptomatic hyperuricemia after renal transplantation.Methods The pharmacist was on duty at the organ transplant outpatient clinic.During this time,they analyzed and sorted out the medications,identified and differentiated a case of asymptomatic hyperuricemia related to spironolactone in a patient who had undergone a renal transplant,and provided comprehensive care throughout the entire process.Results The asymptomatic hyperuricemia in this patient might be associated with spironolactone,and the adverse reactions of the patient were alleviated by pharmacists through optimizing clinical treatment.Up to now,no hyperuricemia occurred.Conclusions Pharmacists are required to collaborate closely with clinicians to establish medication profiles for patients under long-term follow-up and to closely monitor and evaluate drug-related adverse reactions.Additionally,they should assess the renal function and immune status of transplant recipients promptly and formulate individualized treatment plans in order to enhance the long-term survival of both the transplanted kidneys and the recipients.

AIM: To establish individualized drug therapy strategy for patients with rejection and hyperglycemia after liver transplantation. METHODS: Clinical pharmacist collaborated with the surgeons and participated in the diagnosis and treatment of rejection and hyperglycemia after liver transplantation. Taking together liver function, therapeutic drug monitoring, drug-drug interactions between tacrolimus and wuzhi capsule, individualized drug therapy was adapted to improve the prognosis. RESULTS: The patient recovered well and survived in good health till now. CONCLUSION: It is highly suggested that clinical pharmacists actively involved in treatment of more severe and difficult-to-treat disease and design the individualized dosing regimens. This will largely contribute in reduced adverse drug reaction, improved safety and effectiveness in drug use as well as the quality of life in the "post-transplantation era".

AIM: To investigate the effects of age, gender, duration of medication and combined medication on the steady-state blood concentration of tacrolimus in patients with autoimmune diseases, and to establish the reference range of steady-state blood concentration of tacrolimus in combination with liver and kidney function, so as to provide theoretical basis for clinical individual medication. METHODS: A total of 107 patients with autoimmune diseases treated with tacrolimus in the department of rheumatology and immunology of our hospital from August 2017 to June 2021 were included. Their gender, age, dose, drug combination, blood concentration, and liver and kidney function were statistically analyzed by SPSS 22.0 statistical software. RESULTS: In the treatment of autoimmune diseases with tacrolimus, there was statistical significance in the blood concentration of different genders (P<0.05), but there was no statistical significance in the blood concentration of different ages (P>0.05) and a statistically significant difference in the dosage of tacrolimus (P<0.05), the duration of medication did not affect the effective dose, target blood concentration, liver and kidney functions. There was a weak correlation between tacrolimus dose and blood concentration (r=0.115, P=0.047). When the blood concentration of tacrolimus ranged from 4.20 to 9.48 ng/mL, the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and urea increased significantly. When tacrolimus blood concentration ranged from 0.08 to 4.20 ng/mL, there was no significant difference in serum creatinine, AST, ALT, albumin, total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL). CONCLUSION: Tacrolimus is used for the treatment of autoimmune diseases, and the blood concentration varies greatly among individuals. To avoid the risk of potential damage to liver and kidney function. It is recommended that clinicians control the blood concentration at 0.08-4.20 ng/mL, and adjust the dose and optimize the dose according to the patient's gender, age, and clinical efficacy.

OBJECTIVE:To explore the role of clinical pharmacists participating in the individualized treatment for purulent meningitis. METHODS:Clinical pharmacists participated in the therapy for a patient with purulent meningitis complicated with Staphylococcus aureus infection. According to patient's condition,clinical pharmacists assisted physicians to formulate preliminary therapeutic plan. Reviewing relevant guidelines,domestic and foreign literatures,clinical pharmacists suggested to combine with dexamethasone so as to relieve inflammatory reaction. According to the results of drug sensitivity test,based on vancomycin plasma concentration monitoring and population pharmacokinetics model fitting,clinical pharmacists suggested to reduce the dose of vanco-mycin to 0.5 g,ivgtt,q12 h. The pharmaceutical care were conducted throughout the therapy,including efficacy evaluation of an-ti-infective therapy,ADR monitoring,renal function monitoring,etc. RESULTS:Physicians adopted some suggestions of clinical pharmacists. The disease condition of the patient was recovred,and no ADR related to vancomycin was found. On the 16th day, the patient was discharged from the hospital. CONCLUSIONS:Clinical pharmacists participate in treatment of purulent meningitis, assist physicians to optimize therapy plan based on relevant guideline,literature,etiological examination,blood concentration moni-toring and pharmacokinetics model fitting results. It not only guarantee therapeutic efficacy of anti-infective therapy,but also pre-vent and reduce the occurrence of ADR.

Flavanoids are important phytochemistry compositions in foods and traditional Chinese medicines (TCM) and are mainly oxidized by CYP1A family in vivo. Some methoxyflavones could also be metabolized through demethylation. Usually, flavanoids own one or more phenolic hydroxyl group in their molecular structures, which facilitate conjugation with glucuronic acid and sulphuric acid, forming metabolites with good water-solubility to excrete. Natural flavanoids mainly exist in glycoside, and after oral ,they would be easily metabolized to aglycone by hydratase in gut microflora and then absorbed into blood. Besides, many flavanoids have strong inhibitory actions on Cytochrome P450 enzymes, which are significant mechanisms in cancer precaution and tumor inhibition. In this paper, we reviewed lots of articles and summarized metabolism characteristics of flavanoids and metabolism interaction with Cytochrome P450 enzymes.

Objective To analyze the genotype of Japaneso encephalitis virus (JEV) strains isola-ted in 2004 from mosquitoes collected in Bazhong city, Sichuan province of China, and the characters of amino acid in the PrM and E gene. Methods The isolated virus strains from mosquitoes were identified by biological, serological and molecular biology. PrM and E segments of the isolated JEV were amplified by RT-PCR, the PCR products were purified and sequenced. Multiple alignment, phylogenetic and amino acid (AA) analysis were carried out by Clustal X (1.8) , MEGA4 and GENEDOC (3.2) . Results The total of 4688 mosquitoes were collected including Armigeres and Culex. Six isolates were identified be-longing to genotype 1 JEV. The comparison between new genotype 1 JEV strains and live attenuated vaccine strain SA14-14-2 in PrM and E gene showed that total 3 sites amino acid differences in PrM gene and 14 sites in E gene, respectively. Three sites (PrM2, 64 and 65 ) in PrM protein and four sites (E129, 222,327 and 366) in E protein were only belonging to genotype 1 JEV. Conclusion The new isolated JEV strains in Sichuan province belong to genotype 1. It suggests that the vaccine strain SA14-14-2 currently used for preventing Japanese encephalitis is able to protect people against JEV, although in the segments of it had some amino acid differences between vaccine strain and the epidemic genotype 1 JEV strains in PrM and E gene.
