OBJECTIVE To establish a pharmaceutical management model for infusion safety in hospitalized inpatients and ensure the safety of drug use. METHODS Our hospital established the standardized management process for infusion scheme， formulated rules for compatibility contraindications in drug combinations. In the form of embedded hospital official account, the infusion scheme and medication guidance WeChat developed by pharmacists are pushed to the mobile phone of inpatients, providing electronic medication guidance services for patients, and forming a pharmaceutical management model for infusion safety of inpatients. RESULTS Our hospital provided a total of 45 291 inpatients with pharmaceutical services including the formulation of individualized infusion scheme and WeChat push infusion scheme and medication guidance as of December 2023. After the implementation of the management model， the intervention rate of pharmacists on the compatibility contraindications in drug combination of long-term medical orders for inpatients increased from 18.25% before implementation to 90.58% （P＜0.01）， and the satisfaction rate of inpatients increased from 87.50% to 94.50% （P＜0.05）. CONCLUSIONS The pharmaceutical management model for infusion safety of hospitalized patients integrates pharmaceutical services throughout the entire process of intravenous medication treatment. Pharmacists can participate in the management of infusion usage while providing qualified finished infusion products, achieving closed-loop management of pharmaceutical services, improving the hospital’s pharmaceutical service capabilities and patient satisfaction, and providing guarantees for the safety and effectiveness of patient medication.

OBJECTIVE To explore comprehensive management and potential issues associated with long-term prescriptions medications of psychiatry， in order to provide a reference for the comprehensive management of long-term prescriptions of psychiatry in psychiatric hospitals and other medical institutions’ pharmacies. METHODS Starting from the applicable principles for long-term prescriptions of psychiatry， this study introduced the standardized assessment and precautions before issuing long-term prescriptions， the formulation and adjustment of the drug list， as well as the rational management of the long-term prescriptions. It also analyzed potential issues that may arise in the comprehensive management of long-term prescription medications and proposed corresponding countermeasures and suggestions. RESULTS & CONCLUSIONS Prior to initiating long-term prescriptions， a standardized assessment should be conducted on patients from the aspects of their psychiatric condition and long-term potential risk factors， pharmacological treatment plans and other non-pharmacological therapies， physical illnesses. Additionally， healthcare providers should fulfill their obligation to inform patients or their family members. The comprehensive management of long-term prescription medications should be jointly established and improved by multiple departments， and the formulation of drug catalogs should avoid including drugs with potential social harm or medication risks while complying with policy requirements. Furthermore， measures such as adding special identifiers to long-term prescriptions， providing patients with reminders about （No.YGLX202537） prescription expiration， or offering online consultations can also effectively enhance the rationality of medication use under long-term prescriptions. Currently， the implementation of long-term prescriptions in psychiatry remains challenged by inconsistencies in prescription duration， incomplete coverage of diagnostic categories， poor patient adherence， and the risk of deviation in clinical assessments. In this regard， measures such as collaborating with multiple departments to strengthen long-term prescription information management， providing matching pharmaceutical services， ensuring the quality and rationality of long-term prescription implementation， and using modern methods to screen high-risk patients can be taken to improve patient medication compliance and safety.

OBJECTIVE To provide a reference for the improvement of the clinical pharmacy undergraduate internship education in China. METHODS The status of clinical pharmacy undergraduate internship education in China was briefly summarized， and suggestions on its future development based on advanced methods of domestic and abroad were provided. RESULTS & CONCLUSIONS In China， undergraduate students of clinical pharmacy were required to undergo hospital internships for no less than 42 weeks. The internship took place in both pharmacy and clinical departments in hospitals. Students’ performance was usually assessed at the end of the internship. The mainstream teaching patterns included on-site teaching， simulation teaching， case-based discussion teaching， medical and pharmaceutical joint teaching， team-based teaching， academic exchange， and so on. The form of assessment had also shifted from final evaluations to more dynamic formats. The clinical pharmacy undergraduate internship education in China can adopt teaching models such as the layered teaching approach， establish pre-internship assessment or training， and encourage interns to participate in social pharmacy practice and directly interact with patients， etc.， so as to improve the effect of internship.

Objective:To compare the repair effects of three kinds of treatment methods included synovial mesenchymal stem cells(SMSCs),platelet rich plasma(PRP)and the combination of them with knee joint cavity injection on cartilage injury of rabbit.Methods:A total of 24 New Zealand rabbits were selected to establish a cartilage injury model of knee joint by using surgery in knee joint of them.The rabbits with cartilage injury model were divided into four groups using a random number table method,which included blank group,single SMSCs with joint cavity injection group(SMSCs group),PRP with joint cavity injection group(PRP group)and the combination of SMSCs and PRP with joint cavity injection group(SMSCs+PRP group),with 6 rabbits in each group.The synovium of four groups of rabbits were scraped off their joints to conduct in vitro culture of SMSCs,as well as the morphological observation and identification of SMSCs.The venous bloods of rabbits were extracted to prepare PRP by centrifugation.The contents of PRP,platelet and growth factor in blood were compared.The SMSCs and PRP were injected into the knee joint cavity of three groups of rabbits with model.After 2,4 and 6 weeks of injection treatment,the repair statuses of cartilages at defection area of different groups were evaluated according to cartilage repair scoring table of International Association for Cartilage Repair(ICRS).Results:The primary synovial cells of rabbit knee joint synovium were initially round in shape after isolation,but almost all of them were spindle shaped after passage.The positive detection rates of SMSCs surface antigen CD73,CD90 and CD105 of 4 group were respectively 100%,99.22%and 99.99%.The CD45 detection was 0.5%,which indicated that they possessed the property of stem cell.The platelet count of 4 groups showed that the platelet concentration in PRP was approximate 6 times of that in whole blood.The concentrations of platelet derived growth factor(PDGF),transforming growth factor-β(TGF-β)and vascular endothelial growth factor(VEGF)were respectively(569.15±57.48)ng/mL,(633.56±63.90)ng/mL and(1 243.55±106.04)ng/mL in PRP,which were approximately 5 times,6 times and 7 times of that in whole blood,respectively.After 2 weeks of injection treatment for joint cavity,there was no significant statistical difference in the scores of cartilage repair among 4 groups(P>0.05).At 4 and 6 weeks of injection treatment,the morphological and histological score of cartilage repair of the SMSCs+PRP group were significantly higher than those of the blank group,and the differences were significant(t4 week=6.35,9.15,t6 week=8.16,8.60,P<0.05),respectively.Conclusion:The repair effect of SMSCs combined with PRP on cartilage injury of rabbit is significantly better than that of single PRP and single SMSCs,respectively,and all of them are better than those without treatment.SMSCs combined with PRP can significantly improve the effect of self-repair of cartilage injury.

Objective:To assess the efficacy of neoadjuvant treatment with PD-1 (programmed cell death protein 1) inhibitors combined with paclitaxel (albumin-conjugated) and cisplatin (TP regimen) for locally advanced hypopharyngeal squamous cell carcinoma and laryngeal organ function preservation.Methods:Data of 53 patients, including 51 males and 2 females, aged 38-70 years old, who were diagnosed with locally advanced hypopharyngeal squamous carcinoma confirmed by histology and enhanced CT at the Cancer Prevention and Control Center of Sun Yat-sen University during the initial treatment from January 1, 2019 to January 15, 2023, were retrospectively analyzed. All patients received neoadjuvant therapy with PD-1 inhibitors combined with albumin-bound paclitaxel (260 mg/m 2) and cisplatin (60 mg/m 2) for 3 to 4 cycles. The main outcome measures were larynx dysfunction-free survival (LDFS), overall survival (OS), and progression-free survival (PFS). Survival curves were plotted using the Kaplan-Meier method, and Cox multifactorial analysis was further performed if Cox univariate analysis was statistically significant. Results:The overall efficiency was 90.6% (48/53). The 1-year and 2-year LDFS rates were 83.8% (95% CI: 74.0% to 94.8%) and 50.3% (95% CI: 22.1% to 91.6%), the 1-year and 2-year OS rates were 95.2% (95% CI: 88.9% to 100.0%) and 58.2% (95% CI: 25.6% to 81.8%), and the 1-year and 2-year PFS rates were 83.9% (95% CI: 74.2% to 94.9%) and 53.5% (95% CI: 32.1% to 89.1%). Adverse events associated with the neoadjuvant therapy were mainly myelosuppression (45.3%), gastrointestinal reactions (37.7%) and hypothyroidism (20.8%). Conclusion:The neoadjuvant treatment of locally advanced hypopharyngeal squamous cell carcinoma using PD-1 inhibitors combined with paclitaxel and cisplatin can provide with a higher survival rate with a improved laryngeal organ function preservation rate.

Objective:To assess the safety and feasibility of selectively preserving the first branch of the right gastro-omental artery using bidirectional dissection in laparoscopic pylorus-preserving gastrectomy (LPPG).Methods:In this retrospective analysis, we studied preoperative, intraoperative, postoperative, and follow-up data of 30 patients with early gastric cancer treated in the Department of Gastric Cancer in Zhejiang Cancer Hospital (28 patients), Department of Gastrointestinal Surgery in Jiaxing Second Hospital (one patient) and Department of Gastrointestinal Surgery in Hangzhou Red Cross Hospital (one patient) who had undergone selective preservation of the first branch of the right gastro-omental artery during LPPG. The main variables studied were as follows: (1) intraoperative preservation of the first branch of the right gastro-omental artery; (2) the overall surgical situation; and (3) postoperative small bowel follow-through and endoscopy findings.Results:LPPG with selective preservation of the right gastro-omental artery vascular branch was achieved in all 30 of the study patients. The mean operation time was (244.3±29.3) minutes and the median intraoperative blood loss 50 (20–200) mL. The median tumor diameter was 1.2 (0.5–3.6) cm and an average of 32.3±11.6 lymph nodes were dissected. The overall median number of positive lymph nodes was 0 (0–6), and of No. 6 lymph nodes 5.1±1.5. Postoperative feeding resumed at an average of 5.2±0.5 days and the postoperative hospital stay averaged 8.4±3.4 days. Pathological stages were as follows: T1a (14 cases), T1b (10 cases), and T2 (6 cases). Small bowel follow-through imaging showed good results in 28 patients 5 days post-surgery, the remaining two exhibiting good results 9 days post-surgery. There were no instances of delayed gastric emptying, and only one patient (3.3%) developed intra-abdominal infection (resolved with conservative treatment).Conclusion:Selective preservation of the right gastro-omental artery during laparoscopic early gastric cancer surgery is a safe and feasible procedure for treating early mid-gastric body cancer with pyloric preservation.

In order to establish the isolation,culture and identification method of cow bone marrow-derived macrophages,three different media(RPMI-1640,DMEM,DMEM/F12)were added with 20％fetal bovine serum(FBS),2.4％chlorine-streptomycin,1.2％glutamine(Gln),and M-CSF(20 ng/mL),respectively,to induce the monocytes extracted from the bone marrow of dairy cows to become macrophages.The induced M0 macrophages were polarized into M1-type macrophages by adding lipopolysaccharide(LPS).The morphology of macrophages was observed by optical mi-croscope at day 1,4 and 7,and the differences of differentiated macrophages between the three media were compared.The effects of prostaglandin D2(PGD2)-DP2 receptor pathway on the secre-tion of cytokines(IL-6,TNF-α)induced by Escherichia coli and phagocytosis of macrophages were also investigated.The results showed that the morphological changes of cells cultured in the medium of RPMI-1640 were the most obvious and the number was large.A large number of char-acteristic markers of mononuclear macrophages were detected(M0 markers:CD1 1b,CD14;M1 markers:CD11b,CD80)expression,M0 and M1 macrophage purity were 79.9％and 93.5％,re-spectively.COX-2 and H-PGDS gene expressions were significantly increased in E.coli group com-pared with the blank control group.The secretion of PGD2also increased significantly(P＜0.000 1).DP2 receptor inhibitors(CAY10471,CAY10595)could significantly inhibit the secretion of E.coli in-duced pro-inflammatory cytokines(IL-6,TNF-α)and significantly enhance the killing effect of macrophages on E.coli.The above results showed that the induced cells had the characteristic mor-phology and immunophenotype of macrophages.E.coli can induce the production of PGD2 in mac-rophages,and the PGD2-DP2 pathway regulates the secretion of cytokines in E.coli infected macro-phages.

Hepatic venous pressure gradient (HVPG) is the "gold standard" for the diagnosis of portal hypertension, which could be applied in the evaluation of liver cirrhosis. Combined use of HVPG with model for end-stage liver disease (MELD) scoring system may more accurately match the donors and recipients undergoing liver transplantation for liver cirrhosis, select the appropriate timing of surgery, and provide guidance for bridging treatment for patients on the waiting list for liver transplantation. Besides, HVPG may also predict clinical prognosis of liver transplant recipients, and provide evidence for early detection and intervention of potential complications. Therefore, the value of HVPG in preoperative evaluation and prognosis prediction of liver transplant recipients was reviewed, aiming to provide guidance for clinical diagnosis and treatment of liver transplant recipients before and after surgery.

Objective:To compare the accuracy of different stone scoring systems for predicting the stone-free rate (SFR) after retrograde intrarenal surgery (RIRS).Methods:The clinical data of 227 patients with lithiasis undergoing RIRS from June 2017 to December 2020 in Affiliated Benq Hospital of Nanjing Medical University and Qingdao Fuwai Hospital were retrospectively analyzed. There were 152 males and 75 females. The average age was (53.0±10.4) years old. The average body mass index was (26.9±2.1)kg/m 2. The maximum diameter of the stone was (22.7±12.8)mm. The stone is located in left side in 133 cases and in right side in 94 cases. The stones of 44 cases were located in upper ureter, upper calyceal or renal pelvis, that of 23 cases were in medium calyceal, 157 cases in lower calyceal, and 3 cases in calyceal diverticulum.The average CT value of stone was (778.3±350.4)HU. American Society of Anesthesiology (ASA)scores: 86 cases of grade Ⅰ, 129 cases of grade Ⅱ, 12 cases of grade Ⅲ. Preoperative non-contrast CT was conducted and three-dimensional data were constructed. A single observer reviewed and entered the modified S.T.O.N.E., RUSS, modified S-ReSC, R. I.R.S., SHA.LIN, Ito nomogram, S. O.L.V.E., stone free index (SFI) scores. Logistic analysis were performed between every score and SFR. Receiver operating characteristic (ROC) curve was drawn to detect sensitivity and specificity of every score in predicting the SFR. The predictive accuracies of all scores were compared. Results:The SFR was 83.0%(189/227). There were statistically significant differences in modified S. T.O.N.E.(10.5±1.9 vs. 12.7±1.8), RUSS[1(0, 4) vs. 3(0, 6)], modified S-ReSC (8.2±5.6 vs. 11.8±6.0), R.I.R.S.(6.2±1.4 vs. 8.1±1.2), SHA.LIN (9.9±2.4 vs. 13.0±2.1), Ito nomogram (12.1±5.8 vs. 4.3±3.3), S. O.L.V.E. (6.8±1.6 vs. 8.7±1.2), SFI score (7.9±1.1 vs. 6.3±0.9) between the stone-free group and the stone remaining group ( P <0.05). Logistic regression revealed that modified S.T.O.N.E., RUSS, modified S-ReSC, R. I.R.S., SHA.LIN, Ito nomogram, S. O.L.V.E. and SFI score were significantly associated with SFR( P<0.05). There were no significant differences in the area under the curve (AUC) between the modified S. T.O.N.E., RUSS, R. I.R.S., SHA.LIN, Ito nomogram, S. O.L.V.E. and SFI score( P>0.05), but there were significant differences in the AUC between modified S-ReSC score and other score ( P<0.05). When the cutoff of SHA.LIN, SFI and R. I.R.S. score was determined as 10, 6 and 6 scores, the specificity of SHA.LIN, SFI and R. I.R.S. score was 94.7%, 92.6% and 89.5%, respectively. Conclusions:All score could predict the postoperative SFR of RIRS, while the SHA.LIN, SFI and R.I.R.S. score were more accurate than the other scores. The accuracy of the modified S-ReSC in predicting SFR after RIRS was slightly worse than other scores.
