Aim To establish the pharmacokinetic-pharmacodynamic(PK-PD) modeling to characterize the antipyretic effects of coptisine, an active component in coptis chinensis on rats.Methods Nine healthy male Sprague-Dawley(SD) rats were randomly divided into three groups, each with three.The rats in the first group were injected intravenously with lipopolysaccharide(LPS,100 μg·kg-1) alone.The second and third group rats were given coptisine high-dose(3.87 mg·kg-1) and coptisine low-dose(1.93 mg·kg-1) by tail vein injection at 30 min after LPS injection, respectively.Body temperature was measured at different time points, and blood samples from tail vein were collected simultaneously.The blood concentration of coptisine was determined by ultra performance liquid chromatography.Monolix software was used to model PK-PD of coptisine mean plasma concentration and temperature effects,by population computation with non-covariates.Besides.the model with advantage was selected by the fitting goodness.Results Coptisine could inhibit body temperature of endotoxin-induced fever in rats significantly.Two-compartment linear elimination model was used to describe the final PK model.Gaussian function, an input function of body temperature changes, which was used to depict PD model, the PK and PD models were connected by the Emax model.At last, the final model was fitted better;the fitting results indicated that the EC50 of antipyretic effect of coptisine was 89.7 μg·L-1, and the Emax was 1.88℃.Conclusions Coptisine has a powerful anti-pyretic effect on endotoxin-induced pyrexia of rats with high potency, Low in vivo distribution and quick clearance.

Objective To evaluate effects of daily average temperature on the occurrence of urticaria in Lanzhou city,and to analyze differences in the effects between different populations.Methods Time-series data on daily outpatient visits for urticaria between January 1,2007 and December 31,2013 were collected from the First Hospital of Lanzhou University and Lanzhou University Second Hospital.Daily meteorological data during this peroid were obtained from the Gansu Meteorological Bureau.Distributed lag non-linear models were used to analyze the association between daily average temperature and occurrence of urticaria,and the analysis was stratified by age and gender.Results The association between daily average temperature and daily number of outpatient visits for urticaria was nonlinear.Low temperature had significant lag effects on the daily number of outpatient visits for urticaria,with the maximum relative risk (RR) value (1.014 [95％ CI 1.000-1.023]) observed at 6 ℃ on lag day 18.Stratification analysis demonstrated that the effects of high temperature on the number of outpatient visits for urticaria were apparent on the day of exposure in age groups of 0-18 and 19-64 years,but decreased on the day of exposure in the age group ≥ 65 years.The effects of low temperature,which showed similar trends along with the increment of lag days in all groups,were relatively delayed and occurred 2 to 4 days after exposure.Conclusions Air temperature affects the occurrence of urticaria in Lanzhou city.Low temperature has evident lag effects on the occurrence of urticaria,while high temperature does not have.

Objective To evaluate effects of the daily average temperature on the daily number of outpatient visits for eczema in Lanzhou city.Methods Clinical data were obtained from outpatients with eczema in the Department of Dermatology of 2 third-grade class-A hospitals in Lanzhou city from January 1st 2007 to December 31st 2015,and meteorological data during this period were also collected.Controlling for confounding factors like long-term trends and day of the week,a distributed lag non-linear model (DLNM) fitted with quasi-Poisson link function was used to assess the effects of daily average temperature on the daily number of outpatient visits for eczema,and the analysis was stratified by season,age and gender.Results The exposure-response relationship between the daily average temperature and daily number of outpatient visits for eczema could be roughly described by a W-shaped curve.Stratification analysis showed that the effect of the daily average temperature on outpatient visits for eczema was strongest in autumn and winter,followed by summer,and weakest in spring.Low temperature may have lagged,cumulative and persistent effects on the daily number of outpatient visits for eczema,with the maximum relative risk (RR) value (1.12 [95％ CI:1.03-1.22]) observed at-9 ℃ on lag day 14.With a 1 ℃decrease in the temperature,16％ (RR =1.16,95％ CI:1.00-1.03),14％ (RR =1.14,95％ CI:1.02-1.26) and 13％ (RR =1.13,95％ CI:1.02-1.25) increases in the daily number of outpatient visits for eczema were observed in men,teenagers and middle-aged adults respectively (P ＜ 0.05).However,low temperature had no significant effects on outpatient visits for eczema among women or the elderly (P ＞0.05).The effect of high temperature usually occurred following exposure without lag periods,and was gradually weakened over lag time (P ＞ 0.05).Conclusions In Lanzhou,the effect of daily average temperature on outpatient visits for eczema was strongest in autumn and winter.Changes of the daily temperature may be one of risk factors for eczema.Low temperature had lagged effects on the daily number of outpatient visits for eczema,and the effects were strongest on lag day 14.

Objective To study the effect of clinical pharmacist interventions on the rational use of antibiot-ics.Methods 1 000 hospitalized patients before the implementation of intervention in April 2012 to April 2013 (control group)and the other 1 000 cases of hospitalized patients in May 2013 to May 2014 after the implementation of the intervention (study group)were selected,the antibiotics use rate,hospitalization time and cost,cost of using antibacterial drugs were compared between the two groups.Results The antibiotics use rate of the study group was 56.0%(560/1 000),significantly lower than 78%(780/1 000)of the control group,with significant differences between the two groups(χ2 =11.089,P=0.032),the hospitalization time,cost of using antibacterial drugs of the study group were (12.6 ±0.8)days,(912.2 ±13.2)yuan,significantly better than (16.9 ±0.7)days,(1 528.1 ± 32.5)yuan of the control group,with significant differences between the two groups (t=9.892,10.142,P=0.028, 0.014);The two groups of hospitalization expenses showed no statistical significance (t =4.984,P =0.072 ). Conclusion Clinical pharmacist intervention has a positive effect on the application of antibacterial drugs,which can significantly reduce the use of antimicrobial drugs and reduce the hospitalization days.

Objective To study the effect of comprehensive Chinese medicine therapy,including Chinese herbal medicine fumigation,massage,and quadriceps exercise,on adipokines of visfatin and chemerin content in joint fluid of patients with knee osteoarthritis (KOA),and to explore its possible therapeutic mechanism for KOA.Methods A total of 60 cases of KOA patients were randomly divided into treatment group and control group,30 cases in each group.The treatment group was treated with comprehensive Chinese medicine therapy,and the control group was treated with Chinese medicine fumigation alone.After treatment for 2 weeks,the clinical efficacy of both groups was evaluated,and the changes in the scores of the Western Ontario and McMaster Universities Arthritis Index (WOMAC)were observed.Moreover,the contents of visfatin and chemerin in jointfluid were examined.Results (1) The total effective rate of the treatment group was 96.7％ and that of the control group was 83.3％,the difference being significant (P ＜ 0.01).(2) After treatment,WOMAC scores of both groups were obviously decreased(P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P ＜ 0.01).(3) The contents of visfatin and chemerint in joint synovial fluid of both groups were decreased (P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group(P ＜ 0.05).Conclusion The comprehensive Chinese medicine therapy of Chinese herbal medicine fumigation,massage and quadriceps exercise is effective for the treatment of KOA,and can decrease the contents of visfatin and chemerin in joint fluid of KOA patients,which may be one of its therapeutic mechanisms.

Objective To clarify the mechanism of immediate early response gene 5 (ler5)transcription induced by radiation. Methods Deletant construction, site-specific mutagenesis,electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP) were used to forecast the promoter region,binding sites and transcription factors of Ier5 gene in HeLa cells.Results The promoter region of Ier5 gene might be in the region of Ier5 -8 deletant ( -408 - -238 bp).The Ier5 gene had two transcription factors of GCF and NFI,and GCF had two binding sites located in the region of - 388 - - 382 bp and - 274 - - 270 bp of Ier5 promoter.The binding site of NFI was located in - 362 --357 bp of Ier5 promoter. GCF could inhibit the expression of Ier5 gene and this inhibition was diminished when the radiation dose increased. In contrast, NFI increased the expression of Ier5.Conclusions The most possible region of Ier5 promoter is from -408 to - 238 bp which has two binding sites for the radiosensitivity transcription factors of GCF and NFI that could negatively and positively regulate the expression of Ier5 respectively.

Objective: To investigate whether silencing UCP2 can sensitize cervical cancer cell line Siha to radiation. Methods: Siha cells were transfected with UCP2 siRNA and then irradiated by X-ray. The radiosensitivity of Siha cells was verified by colony formation, CCK-8, apoptosis and immunofluorescence assays. The mitochondrial membrane potential and the production of reactive oxygen species (ROS) were detected to further explore the related mechanism. Results: RT-PCR and Western blot assays showed that the expression of UCP2 in Siha cells was increased after irradiation and the UCP2 siRNA successfully silenced the expression of UCP in cells. According to the survival curves, the D₀, D_q, N and SF₂ were 1.54, 1.31, 2.31 Gy and 0.52 for siUCP2 group, 2.50, 3.64, 4.30 Gy and 0.83 for blank control group, and 3.34, 2.16, 1.91 Gy and 0.69, for siNC group, respectively. The radiosensitivity enhancement ratio of silent group was 0.62 and 0.46, compared with blank control group and negative control group, respectively. The proliferative activity of cells in the silent group was lower than that in the control group (t=13.2, P<0.05). Apoptosis levels in the silent group were significantly higher than those in the control group after irradiation(t=3.14, P<0.05). At 4 h after irradiation, the ROS production in the silent group was significantly higher than that in the control group (t=19.10, P<0.05). At 24 h after irradiation, the mitochondrial membrane potential of Siha cells in the silent group was significantly lower than that in the control group (t=4.18, P<0.05). Conclusions The radiosensitivity of Siha cells is enhanced after UCP2 silencing, and thus UCP2 may applicable as a new target for radiosensitization of cervical cancer cells.

Objective:To collect and analyze laboratory indicators of patients of different sexes after blood transfusion, evaluate the effectiveness of blood transfusion, and provide a theoretical basis for formulating more scientific blood transfusion plans.Methods:The clinical data of 808 patients who underwent blood transfusion in The First Affiliated Hospital of Anhui University of Science and Technology from January 2020 to December 2021 were retrospectively analyzed. According to the blood transfusion strategy and the department to which the patients were admitted, these patients were divided into four groups: surgical restrictive blood transfusion group (group A: 72 males and 69 females), surgical non-restricted blood transfusion (group B: 77 males and 118 females), medical restrictive blood transfusion (group C: 184 males and 126 females), and medical non-restricted blood transfusion (group D: 110 males and 52 females). Univariate and multivariate Logistic regression analyses were performed.Results:In group A, after blood transfusion, hemoglobin level in female patients was significantly higher than that in male patients [79.0 (71.5, 87.0) g/L vs. 75.5 (69.0, 82.8) g/L, Z = -2.18, P = 0.029], and C-reactive protein in female patients was significantly lower than that in male patients [21.3 (0.0, 56.0) mg/L vs. 37.0 (3.3, 95.5) mg/L, Z = -1.97, P = 0.049]. In groups B, C, and D, there were no significant differences in hemoglobin, C-reactive protein, and hematocrit between male and female patients (all P > 0.05). Multivariate analysis showed that the difference in hemoglobin levels between before and after blood transfusion was statistically significant ( P = 0.009). After a blood transfusion, hemoglobin level in female patients was 1.44 times that in male patients. Conclusion:The tolerance of female patients to blood loss is higher than that of male patients in surgical restrictive blood transfusion, so the threshold value of hemoglobin given to female patients during blood transfusion can be lower than that of male patients. In the case of the same blood loss, priority of blood transfusion can be given to male patients. In the case of scarce blood resources, the total amount of blood transfused for female patients can be approximately reduced.
