OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective To compare the preparation efficiency of mouse pox and mouse hepatitis antibodies between two substrains of BALB/c and Big-BALB/c (B-BALB/c) mice, and to provide a theoretical basis and reference for the selection of laboratory animals in the preparation of monoclonal antibodies inducedin vivo through hybridoma.Methods Individuals weighing more than 5% of the weight of normal animals at 4 weeks of age (the criterion for late selection is more than 10%) were selected from a population of conventionally bred BALB/c mice and bred individually, and a subline of B-BALB/c mice was prepared after 10 generations of selection. A total of 40 BALB/c mice and 40 B-BALB/c mice aged 10 to 11 weeks, half male and half female, were selected and inoculated with the mousepox monoclonal antibody hybridoma cell line G23 or the murine hepatitis monoclonal antibody hybridoma cell line Y15 pre-treated with liquid paraffin, respectively. Mice ascites containing monoclonal antibodies were obtained by in vivo induction. The antibody titer was tested by indirect ELISA. The mice were grouped based on the sub-strains, gender and inoculation type of hybridoma to analyze the ascites production, antibody titer and antibody production, and to evaluate the antibody preparation efficiency of the two BALB/c mouse sub-strains.ResultsAfter 10 generations of breeding, the body weight of 10-week-old male and female B-BALB/c mice increased by 22.3% and 12.8%, respectively, compared with BALB/c mice of the same age. Compared with BALB/c mice, B-BALB/c mice had better tolerance and adaptation to secondary ascites collection. Compared with BALB/c mice, the ascites production and antibody titer during the preparation of antibodies in B-BALB/c mice were significantly increased, especially in the hybridoma cell line G23 vaccination group (both P＜0.000 1) . After inoculation with the hybridoma cell lines G23 or Y15, the average antibody production of B-BALB/c mice (14.99×10⁴ U and 33.22×10⁴ U) was higher than that of BALB/c mice (5.33×10⁴ U and 19.31×10⁴ U) (both P＜0.01). After inoculation with hybridoma cell line G23, the average antibody production per unit body weight of B-BALB/c mice (0.55×10⁴ U/g) was higher than that of BALB/c mice (0.23×10⁴ U/g) (P＜0.000 1). And the antibody production per unit body weight of female B-BALB/c or BALB/c mice was higher than that of male B-BALB/c or BALB/c mice (bothP＜0.01).Conclusion B-BALB/c mice can be used as an alternative to BALB/c mice in the in vivo induction of monoclonal antibody preparation, which can achieve the purpose of reducing the number of experimental animals used, lowering the labor cost, and improving the efficiency of antibody preparation.

OBJECTIVE To ex plore the economic value of medication therapeutical management （MTM）service for patients with stable coronary disease. METHODS Totally 140 patients with stable coronary disease were divided into a control group and a intervention group ，70 cases in each group. Patients in control group were received routine medical services ，and patients in intervention group additionally received standardized MTM services on this basis. Medication complication ，satisfaction degree ， safety indexes and efficacy indexes were compared between 2 groups. From the perspective of the whole society ，the economic value of MTM service for patients with stable coronary disease were evaluated by pharmacists using cost minimization analysis. RESULTS A total of 15 patients did not complete the study ，including 5 cases in intervention group and 10 cases in control group ； there was no death endpoint during the follow-up period. MMAS- 8 score，satisfaction score of drug communication dimension and score of overall satisfactionin of intervention group were obviously higher than control group （P＜0.01）. There was no significant difference in blood pressure standard rate ，blood lipid standard rate ，the incidence of adverse drug reaction ，and the incidence of acute coronary events between 2 groups（P＞0.05）. The total cost of intervention group was lower than that of control group （P＜ 0.01）；the results of sensitivity analysis were consistent with those of cost minimization analysis. CONCLUSIONS Pharmacists implement MTM service for patients with stable coronary disease can reduce total cost ，save medical resources and has economic advantages.

Objective:To explore the correlation and mechanism between thalamic network abnormality and cognitive decline in patients with temporal lobe epilepsy (TLE).Methods:A total of 53 patients with unilateral TLE were consecutively enrolled through the epilepsy clinic of the First Affiliated Hospital of Guangxi Medical University from December 2018 to February 2020. During the same recruitment interval, 37 health controls(HC) with matching demographic characteristic were recruited. All subjects were received the Montreal cognitive assessment(MoCA) test and multimodal MRI scanning. Voxel-based morphometry method was used to study the changes of thalamic gray matter volume in patients with unilateral TLE. The structural covariance network and functional connectivity network based on seed points were used to analyze the changes of thalamic network in TLE patients. In addition, the correlations among abnormal thalamic structure, thalamic network and cognitive function score were analyzed. SPSS 22.0 software was used for statistical analysis. Independent sample t-test and Mann Whitney U test were used for inter group comparison. In order to explore the relationship between thalamus and thalamic network and cognitive performance in TLE patients, thalamic volume and gray matter volume and functional connection value of brain areas with abnormal synergistic changes were extracted and correlated with MoCA score. Results:The total score of MoCA in TLE patients (27.0(25.0, 29.0)) was significantly decreased compared with HC (29.0(28.0, 30.0))( Z=-4.601, P<0.001). Whole brain gray matter volume analysis showed that compared with HCTLE patients showed significant volume reduction in left cerebellum, right temporal pole, right fusiform gyrus, straight gyrus, bilateral middle temporal gyrus, thalamus, medial and paracingulate gyrus (GRF adjusted, voxel-level P<0.001 and cluster-level P<0.05). The thalamus-associated structural covariance network analysis revealed that compared with healthy controls, TLE patients exhibited decreased connectivity in right fusiform gyrus (MNI: x=28.5, y=-15.0, z=-34.5), left insula (MNI: x=-33.0, y=-18.0, z=-1.5), right middle temporal gyrus (MNI: x=55.5, y=-51.0, z=9.0), left complementary motor area (MNI: x=-10.5, y=1.5, z=57.0) and right posterior central gyrus (MNI: x=31.5, y=-33.0, z=51.0) ( P<0.001, cluster > 100). The thalamus-associated functional connectivity network analysis revealed that TLE patients exhibited decreased connectivity in left insula (MNI: x=-38, y=-7, z=-7), left lingual gyrus (MNI: x=-6, y=-81, z=-12), right lingual gyrus (MNI: x=15, y=-105, z=0) and left triangular inferior frontal gyrus (MNI: x=-39, y=36, z=-6) (GRF correction, voxel-level P<0.001 and cluster-level P<0.05). Volume of left insula which had decreased structural connectivity with thalamus were positively correlated with the MoCA score in TLE patients( r=0.279, P=0.043). Volume of left complementary motor area which had decreased structural connectivity with thalamus was positively correalated with the MoCA score and language score in TLE patients( r=0.323, P=0.018; r=0.334, P=0.015). Volume of left lingual gyrus which had decreased functional connectivity with thalamus was negatively correalated with the memory score in TLE patients ( r=-0.331, P=0.016). Conclusion:Thalamic volume, thalamic structural covariant network and functional connection network are changed in TLE patients. The abnormality of thalamic network is associated with cognitive performance in TLE patients, which may be the neural mechanism of thalamus participating in the cognitive impairment of TLE patients.

Tendons and bones are connected at the tendon-bone interface to transmit force and exchange biological information. However, the formation of fibrous scars after injury to the tendon-bone interface makes it difficult to recover the original structure during surgery and thus reduces its performance. Therefore, the healing of the tendon-bone interface is a hotspot in sports medicine. Numerous studies have already demonstrated that a variety of molecules and cells participate in the tendon-bone interface reconstruction process, and yet the specific mechanism remains unclear. At present, a great number of studies have been carried out on treatment methods, but clinical treatment are varied with no unification. Therefore, the authors review the advances in the biology and mechanics of healing mechanisms of tendon-bone interface as well as the main methods promoting tendon-bone interface healing, so as to provide references and new ideas for further researches on tendon-bone interface healing.

Wutou-Gancao herb-pair is extensively used to attenuate the toxicity and enhance the efficacy of aconite. In this study, potential synergic mechanism of the herb pair was investigated by utilizing multiple ap-proaches. In silico and in vitro Caco-2 cell models were applied to study the potential binding mode of bioactive ingredients existing in liquorice with P-glycoprotein (P-gp), as well as the inhibition effects on P-gp. Additionally, anti-inflammatory activity of aconitine (AC) combined with active ingredients of liquorice, as well as pharmacokinetic patterns of AC after co-administration was investigated. Anti-inflammatory effect of AC (1 mg/kg) in rats was enhanced in combination with bioactive ingredients of liquorice (10 mg/kg). In the meanwhile, the exposure of AC in vivo was altered, in terms of Cmax and AUC. For instance, the Cmax and AUC were increased to 1.9 and 1.3 folds, respectively, when used in combination with liquiritigenin. The in silico study revealed the potential binding mode with outward facing conformation of P-gp. The resulting data obtained from transport of rhodamine-123 (Rh-123) across Caco-2 cell monolayer further indicated that the function of P-gp was inhibited by chemicals in liquorice. The synergic effect was therefore proposed to be attributed to inhibition of P-gp by liquorice since AC has been demonstrated to be the substrate of P-gp. The resuls revealed that potential synergic mechanism of Wutou-Gancao herb-pair by inhibiting function of key efflux transporter P-gp to enhance the exposure of AC in systematic circulation, and further the anti-inflammatory effect, which helps clarify the compatibility rationale of these two herbs.

This study aimed to investigate the improvement of tolance and pharmacodynamics of nano-micelle irinotecan formulation compared with irinotecan hydrochloride injection(Campto). The toxic effects of the two formulations on colorectal cancer cells COLO205, HT-29, HCT-8 and SW480 were tested in vitro. COLO205 tumor-bearing mouse model was constructed. The two preparations were given via tail vein injection to investigate the maximum tolerance dose(MTD)of tumor-bearing mice to the two preparations, and then to explore the improvement of anti-tumor efficacy of nano-micelle irinotecan formulation near the MTD. The results showed that there was no significant difference in the inhibitory effect of the two formulations on the four colorectal cancer cells in vitro. The MTD of nano-micelle irinotecan formulation and Campto was 432. 0 and 276. 5 mg/m2 respectively. Both of the two formulations showed significant anti-tumor effect in vivo, and the relative tumor proliferation rate and tumor wet weight inhibition rate of nano-micelle irinotecan formulation at high dose(345. 6 mg/m2)were significantly better than those of Campto at two doses(177. 0 and 221. 2 mg/m2)(P< 0. 05).

Objectives? To explore the effects of applying growth mentor program in the training of new nurses. Methods? By convenient sampling, the newly recruited nurses who signed official employment contract with the First Affiliated Hospital of Xi'an Jiaotong University were selected as subject. A total of 756 nurses who enrolled from 2008 to 2012 were put into the control group and 812 nurses enrolled from 2013 to 2017 were in the observation group. The control group received routine training while the observation group received the training of the growth mentor program. The two groups was compared in the resignation rate, annual assessment scores, and patients' satisfaction. Results? The differences in resignation rate between the observation group (0.37%) and the control group (1.06%) were statistical significant (P＜0.01). The annual assessment scores of the observation group (88.63±2.17) and patients' satisfaction (96.78±1.76) were all higher than the control group with statistical significance (P＜ 0.01). Conclusions? The establishment and implementation of the new nurses' growth mentor program can significantly reduce the nurses' resignation rate, improve the nurses' professional skills and patients' satisfaction, therefore the program should be widely applied in new nurses' training in hospitals.
