Objective To analyze and intervene in typical cases of off-label drug uses of efgartigimod in the treatment of Guillain-Barré syndrome,and to provide further medication strategies for the management of Guillain-Barré syndrome.Methods By reviewing the treatment of two cases of Guillain-Barré syndrome,where intravenous immunoglobulin was ineffective or the blood product supply was limited,the clinical pharmacist conducted an evidence-based evaluation of the off-label drug uses of efgartigimod for the treatment of Guillain-Barré syndrome following guidelines and norms,provided assistance to the physician in developing a treatment regimen(10 mg·kg-1 once a week for 4 weeks),and closely monitored and evaluated the medication administration process.Results Two patients had significant improvement and no serious adverse events after treatment with efgartigimod.Clinical pharmacists play an important role in the decision-making,regulation and monitoring of off-label drug uses,ensuring the safety and rationality of medication use.Conclusion Clinical pharmacists should actively involved in the practice of off-label drug uses and make a contribution to the promotion of rational clinical use of medication.

Anlotinib has strong antiangiogenic effects and leads to vessel normalization.However,the"window period"characteristic in regulating vessel normalization by anlotinib cannot fully explain the long-term survival benefits achieved through combining it with other drugs.In this study,through RNA sequencing(RNA-seq)and label-free quantitative proteomics analysis,we discovered that anlotinib regulated the expression of components of the extracellular matrix(ECM),leading to a significant reduction in ECM stiffness.Our bioinformatic analysis revealed a potential positive relationship between the ECM pathway and gefitinib resistance,poor treatment outcomes for programmed death 1(PD-1)targeting,and unfavourable prognosis following chemotherapy in lung cancer patients.We administered anlotinib in combination with these antitumour drugs and visualized their distribution using fluorescent labelling in various tumour types.Notably,our results demonstrated that anlotinib prolonged the retention time and distribution of antitumour drugs at the tumour site.Moreover,the combination therapy induced notable loosening of the tumour tissue structure.This reduction was associated with decreased interstitial fluid pressure and tumour solid pressure.Additionally,we observed that anlotinib effectively suppressed the Ras homologue family member A(RhoA)/Rho-associated protein kinase(ROCK)signalling pathway.These findings suggest that,in addition to its antiangiogenic and vessel normalization effects,anlotinib can increase the distribution and retention of antitumour drugs in tumours by modulating ECM expression and physical properties through the RhoA/ROCK signalling pathway.These valuable insights contribute to the development of combination therapies aimed at improving tumour targeting in cancer treatment.

Objective To evaluate the township hospitals'medical service efficiency in Shandong province,and to provide references for the development in township hospitals under the background of the essential medicine system.Methods The method of data envelopment analysis(DEA)was used to analyze the township hospitals' medical service efficiency in Shandong province before and since the implementation of the essential medicine system.Results For the township hospitals in Shandong province in general,their relative efficiency ratio of the medical service efficiency dropped from 66.67% to 53.33% since the implementation of the essential medicine system.In terms of the input and output,the non-DEA effective township hospitals are found with insufficient output as measured by the output indicator,while some input indicators input were found as excessive.Conclusion The low scale efficiency has become the main factor for the low service efficiency of such hospitals since the implementation of the essential medicine system in Shandong province.In order to improve the medical service efficiency,it is important to continue to improve the essential medicine system,increase the medical staff's incentives, improve the fiscal compensation policy,and keep the policy continuity.

Objective To observe the expression level of inhibitor of differentiation 2 (Id‐2) and matrix metalloproteinases‐9 (MMP‐9) in rectal cancer ,analysis the correlation of the expression level of them ,to study the relationship between the expression level of them and the clinical pathology indicators of rectal cancer .Methods Rectal cancer tissues and normal tissue adjacent to rec‐tal cancer were obtained from the rectal cancer resection of 56 patients with rectal cancer ,using immunohistochemical method to ob‐serve the expression level of Id‐2 and MMP‐9 in normal tissue adjacent to rectal cancer and rectal cancer and Spearman correlation test to detect the correlation between the expression level of Id‐2 and MMP‐9 ;then we analyzed the relationships between the ex‐pression level of Id‐2 and MMP‐9 and the index of rectal cancer clinical pathology .Results The positive expression rate of Id‐2 in the in rectal cancer tissues is more higher than that of normal tissue of adjacent to rectal cancer (73 .21% vs .48 .21% ,P<0 .05) . The positive expression rate of MMP‐9 in the in rectal cancer tissues is higher than that of normal tissue of adjacent to rectal cancer (71 .43% vs .44 .64% ,P<0 .05) .Spearman correlation test showed that there is the positive correlation between the expression level of Id‐2 and MMP‐9 (r=0 .393 ,P=0 .003) .The expression levels of Id‐2 and MMP‐9 in rectal cancer were correlated with the degree of tumor differentiation ,TNM stage and lymph node metastasis (P<0 .05) ,but had no differences between the elements of age and sex (P>0 .05) .Conclusion There is a close relationship between the expression levels of Id‐2 and MMP‐9 in rectal cancer and the occurrence and development of rectal cancer .Rectal cancer with the higher Id‐2 expression level may be the ways to achieve tumor invasion and metastasis through MMP‐9 as a facilitator .

To study performance problems found in China's essential medicine system.The SmithModel of system implementation was called into play in a systematic collation and analysis for the ideal policies,system implementation agencies,target groups and policy environment in its performance,along with relationships among the four factors.The system is found with a number of loopholes as the system itself is highly idealized,its system objectives set inappropriately,problems found with the four factors,and tension and conflicts among these factors.Given these problems found in its performance,it is inappropriate to make drastic changes to avoid instability of the system at its early stage.Government departments in question are advised to comprehensively analyze the four factors and their relationships then taking effective measures to deal with them and the tension,conflict among them.This can ensure effectively implementation of the essential medicine system.

Objective To study the different types of medication guidance for community doctors in the context of essential medicine system,and analyze its influencing factors.Methods SPSS 1 9.0 was called into play for statistical analysis of data gathered,and the medication guidance behavior of the doctors were graded on the two dimensions of personal willingness and practical action.With important quadrant method,the medication guidance behavior of such doctors was classified,while the multiple linear regression was used to study the influencing factors.Results Most of the community doctors of the fourteen counties fall into the area of “high willingness and less action”,with only a few falling into the area of the “high willingness and more action”. Major influencing factors of their willingness on medication guide were found to include impacts on job autonomy,attention to essential medicine system, and the forms to improve income.Major factors of the doctors'actions on medication guide include awareness of essential medicines,awareness of essential medicines catalog,and training outcomes. Conclusion The community doctors have high personal willingness for medication guidance related to essential medicines,but only a number of them carried it in their work.Therefore,it is necessary to take actions to strengthen awareness of the doctors for medication guidance and encourage them to carry it out.
