OBJECTIVE To formulate the Expert Consensus on the Implementation and Management of Drug Selection for Centralized Volume-Based Procurement in Medical Institutions of Guangxi （hereinafter referred to as the “ Consensus ”）， and to provide decision-making support and practical guidance for the drug selection and management of centralized volume-based procurement （hereinafter referred to as “centralized procurement”） drugs in medical institutions at all levels in Guangxi. METHODS A systematic review was conducted on the materials from previous batches of centralized procurement implemented in Guangxi. A comprehensive search was carried out for drug-related works and books， along with a systematic collation of guidelines on drug selection， expert consensus on centralized procurement， and policy documents. Through three rounds of specialized seminars， combined with existing evidence-based data and the practical drug selection experiences of medical institutions at various levels， this Consensus was formulated after thorough discussion and successive rounds of revision. RESULTS & CONCLUSIONS The Consensus systematically outlines the three key stages in the implementation of centralized procurement in medical institutions： procurement volume reporting， confirmation of agreed procurement volume， and procurement and usage implementation. It proposes drug selection strategies for centralized procurement bas ed on multiple dimensions， including specifications， dosage forms， packaging materials， fill volume， and manufacturing enterprises. In response to practical challenges encountered in the selection process， corresponding countermeasures are proposed， such as establishing a regularized information reserve mechanism， strengthening information technology support， and implementing categorized selection approaches. The Consensus advocates for medical institutions to construct an integrated “policy， data， and quality” decision-making system to promote full-cycle management of centralized procurement. This Consensus will provide scientific and practical guidance for medical institutions at all levels in Guangxi in the drug selection of centralized procurement， facilitating the smooth implementation and sustainable development of centralized procurement policies at the institutional level.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

BACKGROUND:The correlation between sacroiliac joint degeneration and lumbar degenerative disease has been analyzed in the literature in the past,but the clinical efficacy and imaging changes after interbody fusion with sacroiliac joint ankylosis in patients with lumbar degenerative disease have not been reported in the literature.OBJECTIVE:To investigate the effect of sacroiliac joint ankylosis on the clinical efficacy and lumbar sagittal regression after L5/S1 single-segment transforminal lumbar interbody fusion in patients with lumbar degenerative disease.METHODS:Thirty-seven patients who underwent L5/S1 segmental transforminal lumbar interbody fusion for lumbar degenerative disease with sacroiliac joint ankylosis between June 2020 and September 2023 in Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed as group A.Thirty-seven patients with lumbar degenerative disease without sacroiliac joint ankylosis who were matched for general information during the same period were selected as controls in group B.Clinical efficacy was assessed using the Oswestry disability index and visual analog scale for lumbar and lower limb pain.The lumbar sagittal parameters included lumbar anterior convexity angle,lumbar partial anterior convexity angle,and lower lumbar anterior convexity angle.Pfirrmann grading was used to assess the degree of preoperative disc degeneration,postoperative endplate damage and screw loosening,and to record the fusion of the operated segments at the final postoperative follow-up visit.RESULTS AND CONCLUSION:(1)There was no statistically significant difference in age,body mass index,bone mineral density,operation time,intraoperative bleeding,preoperative primary diagnosis and postoperative follow-up time between the two groups(P＞0.05).(2)The preoperative Pfirrmann grading of lumbar disc degeneration in group A patients(3.4±0.9)was significantly higher than that of group B(3.1±0.6),and the difference was statistically significant(t=2.059,P=0.044).(3)All patients showed significant improvement in postoperative lumbar sagittal parameters compared with preoperative ones(all P＜0.05).During the follow-up period,there was a loss of correction in patients in group A.There was no statistical difference in the lumbar anterior convexity angle,lower lumbar anterior convexity angle,and local anterior convexity angle at the last follow-up compared with the preoperative period(P＞0.05).The lumbar anterior convexity angle,lower lumbar anterior convexity angle,and local anterior convexity angle in group A were significantly lower than those of group B patients at both preoperative and final follow-up,and the differences were statistically significant(all P＜0.05).(4)There was no statistically significant difference in postoperative endplate injury between the two groups(x2=0.181,P=0.670),and screw loosening was significantly higher in group A than in group B,with a statistically significant difference(x2=4.163,P=0.041).(5)At the last follow-up,the incidence of grade 3 fusion and grade 4 fusion was significantly higher in group A than in group B.The difference in the distribution of fusion grades between the two groups was statistically significant(x2=7.848,P=0.031).(6)The Oswestry disability index and lower limb visual analog scale scores at the last follow-up of both groups were significantly improved compared with the preoperative period(P＜0.05).The visual analog scale scores for low back pain at 3 months after surgery and at the last follow-up of group A were significantly higher than those of group B(t=2.010,P=0.048;t=2.133,P=0.036).(7)It is concluded that regardless of whether it is accompanied by sacroiliac joint ankylosis or not,lumbar degenerative disease patients who undergo interbody fusion with foramen magnum can achieve good therapeutic effects,but lumbar degenerative disease patients with sacroiliac joint ankylosis who undergo interbody fusion with foramen magnum at the L5/S1 segments have a poorer improvement of low back pain than patients without sacroiliac joint ankylosis after the operation.Furthermore,patients with preoperative sacroiliac ankylosis who underwent L5/S1 segmental transforminal lumbar interbody fusion had a low fusion rate and were prone to loss of correction of the lumbar sagittal position.

OBJECTIVE To construct a closed-loop management model for externally dispensed intravenous prescriptions， and to provide reference for standardized management of externally dispensed intravenous prescriptions. METHODS Based on the Expert Consensus on Closed-loop Management of Externally Dispensed Intravenous Prescriptions in Guangxi Zhuang Autonomous Region previously formulated by our hospital， risk points during the entire process were systematically identified through multidisciplinary team brainstorming and a fishbone diagram. A series of strategies were subsequently formulated and implemented， including qualifying designated external dispensing pharmacies and the drug catalogs， operating and maintaining the hospital information system and the Pharmacy Intravenous Admixture Service （PIVAS） intelligent management platform， and strengthening differentiated training for staff in the whole workflow. A whole-process closed-loop management system was constructed with PIVAS as the co re hub and the daytime chemotherapy center as the safety terminal. RESULTS A total of 3 cooperating pharmacies and an initial drug list comprising 35 product specifications were selected. A closed‑loop management process encompassing hospital outpatient prescribing， patient drug purchase in designated pharmacies， PIVAS drug dispensing， and medication use in daytime chemotherapy center was successfully established. This system enabled the mandatory grouping and association of externally dispensed intravenous prescriptions with in-hospital diluents， full-process verification based on drug traceability codes， intelligent monitoring of infusion parameters， and whole-process data traceability. CONCLUSIONS The constructed model effectively resolves the coordination and safety oversight during the use of externally dispensed intravenous drugs from out-of-hospital circulation to in-hospital use， and has preliminarily enabled procedural standardization， whole-process information traceability， and proactive control of medication risks.

OBJECTIVE To conduct a rapid and comprehensive evaluation of commonly used oral dihydropyridine calcium channel blockers （DHP CCBs） in Guangxi， and provide scientific basis for clinical medication and drug selection in medical institutions. METHODS Based on the actual drug use data of public medical institutions at the second level and above in Guangxi Zhuang Autonomous Region， and based on the national centralized collection catalog， commonly used oral DHP CCBs were selected. The Professional Committee of Evidence-based Pharmacy of the Guangxi Pharmaceutical Association organized relevant experts from multiple medical institutions in the region to conduct a quantitative scoring of the selected oral DHP CCBs from five key dimensions of pharmaceutical characteristics， effectiveness， safety， economy， and other attributes， by referring to the Quick Guideline for Drug Evaluation and Selection in Chinese Medical Institutions （the Second Edition）， combined with the latest evidence-based medical research results， and widely soliciting suggestions from clinical and pharmaceutical experts. Finally， the Guangxi Expert Consensus on Rapid Comprehensive Evaluation of Oral Dihydropyridine Calcium Channel Blockers in the Treatment of Cardiovascular Disease was formulated. RESULTS A total of 30 commonly used oral DHP CCBs were selected. Among them， Amlodipine besylate tablets （Huizhi） demonstrated superior comprehensive performance （81.79 points）， excelling particularly in pharmaceutical properties， effectiveness and other attributes. The compound scores of Amlodipine besylate tablets （Chongqing Yaoyou） and Amlodipine besylate tablets （Suzhou Dongrui） ranked second and third respectively， with scores of 81.66 and 81.60 points. CONCLUSIONS This consensus can provide guidance and decision-making support for the rational clinical application of oral DHP CCBs in Guangxi Region and the selection of drug directories in medical institutions.

Objective:To investigate the diagnosis, treatment, and prognosis of primary pancreatic signet-ring cell carcinoma (SRCC).Methods:A retrospective analysis was conducted on clinical data of 11 patients with pathologically confirmed SRCC treated at the Women and Children's Hospital Affiliated to Qingdao University and the Affiliated Hospital of Qingdao University between 2002 and 2024. The cohort included 10 male and 1 female patients, aged (65.6±9.2) years. Data on gender, age, clinical manifestations, biochemical markers, tumor biomarkers, surgical approaches, postoperative pathology, adjuvant the-rapy, and treatment outcomes were recorded. Postoperative survival was assessed via outpatient records and telephone follow-ups.Results:Among the 11 patients, all 10 male patients had a long-term smoking his-tory. Initial symptoms included epigastric pain (5 cases), jaundice (2 cases), postprandial upper abdominal discomfort (3 cases), and persistent hyperglycemia (1 case). Elevated total bilirubin with increased alanine transaminase and aspartate transaminase was observed in 4 cases, while 7 cases had normal liver function. Tumor biomarker profiles showed elevated carcinoembryonic antigen (CEA) alone in 2 cases, elevated carbohydrate antigen 19-9(CA 19-9) alone in 6 cases, concurrent elevation of CEA and CA19-9 in 2 cases, and normal tumor markers in 1 case. Tumor locations included the pancreatic head (8 cases) and pancreatic body/tail (3 cases). All patients underwent radical resection without major perioperative complications. Immunohistochemistry revealed perineural invasion (+ ) in 10 cases and Ki-67 ≥ 50% in 9 cases. Six patients received postoperative adjuvant therapy. The median disease-free survival was 14 months, and the median overall survival was 18 months.Conclusion:SRCC lacks specific clinical manifestations and carries a poor prognosis. Radical surgical resection remains the cornerstone of treatment, while adjuvant therapy may improve survival outcomes.

Objective To explore the effectiveness and safety of transurethral thermal steam ablation for the treatment of benign prostatic hyperplasia(BPH)patients with high-grade and high-risk.Methods Clinical data of elderly BPH pa-tients with high-risk treated with transurethral water vapour thermal from February 2022 to January 2025 were retrospectively ana-lyzed.The operation time,intraoperative bleeding,the number of injections during surgery,postoperative indwelling urinary catheter time,and surgical complications were recorded.And the differences in the International Prostate Symptom Score(IPSS),Quality of Life Score(QOL),Maximum Urinary Flow Rate(Qmax),and Residual Volume of Urine(PVR)before and after 3 and 6 months of the operation were recorded respectively.Results All 30 cases were successfully completed with an operation time of(10.167±2.984)min,intraoperative bleeding of(1.600±1.133)mL,the number of injections during surgery(6.600±1.793).No case of transfusion occurred.And the mean postoperative indwelling urinary catheter time was(8.467±3.246)d.After 3 and 6 months of postoperative follow-up,the Qmax increased from the preoperative(3.463±2.503)mL/s to(10.177±1.625)mL/s and(11.747±1.888)mL/s.PVR decreased from preoperative(209.623±191.960)mL to(40.433±23.713)mL and(30.300±20.223)mL.IPSS score decreased from preoperative(29.533±4.216)to(15.067±3.183)and(12.100±3.546).And QOL score decreased from preoperative(5.033±0.718)to(2.600±0.814)and(2.367±0.850).There were significant differences in observational indexes before and after the operation(P＜0.05).There was no case of postoperative urinary incontinence or secondary bleeding.Conclusion Transurethral water vapour thermal therapy is safe and effective for the treatment of elderly BPH patients with high-risk.

Since the beginning of the 21st century, the severe respiratory infectious diseases worldwide [such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), influenza A H1N1 and novel coronavirus infection have attracted wide attention from all walks of life due to their superior pathogenicity and transmissibility. Aerosols-carrying pathogens are the main transmission route of many severe respiratory infectious diseases, which can lead to severe respiratory failure and even acute respiratory distress syndrome (ARDS) in infected individuals. Mechanical ventilation is the primary treatment for ARDS, and the small tidal volume, appropriate level of positive end-expiratory pressure based lung protective ventilation strategy can effectively reduce the incidence of ventilator-induced lung injury (VILI). However, in the process of clinical treatment, it is sometimes necessary to briefly disconnect the connection between the artificial airway and the ventilator circuit, which will not only cause the residual aerosol in the respiratory system to spill out and pollute the surrounding environment, increase the risk of nosocomial infection including medical staff, but also interfere with the implementation of lung protective ventilation strategy and aggravate ventilator-induced lung injury. In addition, studies have shown that a lot of medical staff have nosocomial infections, especially staff involved in tracheal intubation, extubation and other airway related operations. In addition to enhancing personal protective measures, it is crucial to safeguard healthcare workers from aerosol contamination and minimize associated risks during airway management. At present, there are few researches on the temporary sealing of airway lines and ventilator system, and there is a lack of clear guidance. This review summarizes the research status in related fields to provide a reference for corresponding solutions and programs.

OBJECTIVE: To investigate the frequency and related factors of ineffective triggering (IT) and double triggering (DT) in patients with acute brain injury undergoing invasive mechanical ventilation. METHODS: A retrospective cohort study was conducted using data from a single-center observational trial. Patients with acute brain injury [traumatic brain injury, stroke, and post-craniotomy for brain tumors] undergoing mechanical ventilation in the intensive care unit (ICU) of Beijing Tiantan Hospital, Capital Medical University between June 2017 and July 2019 were retrospectively analyzed. Demographic and clinical data were collected. Respiratory parameters and waveforms during the first 3 days of mechanical ventilation were recorded, with 15-minute waveform segments collected 4 times daily. Airway occlusion pressure (P_0.1) was measured via end-expiratory hold at the end of each recording. IT and DT were identified based on airway pressure, flow, and esophageal pressure waveforms, and the ineffective triggering index (ITI) and DT incidence were calculated. Multivariate Logistic regression was used to identify factors associated with IT and DT. RESULTS: A total of 94 patients with acute brain injury were ultimately enrolled, including 19 cases of traumatic brain injury (20.2%), 39 cases of stroke (41.5%), and 36 cases of post-craniotomy for brain tumor (38.3%). Supratentorial injury was observed in 49 patients (52.1%), while infratentorial injury was identified in 45 patients (47.9%). A total of 94 patients with 1 018 datasets were analyzed; 684 (67.2%) datasets were on pressure support ventilation (PSV), and 334 (32.8%) were on mandatory ventilation. IT was detected in 810 (79.6%) datasets, with a median incidence of 2.1% (0.3%, 12.0%). Datasets demonstrating IT were characterized by lower P_0.1, higher tidal volume (VT), reduced respiratory rate (RR), and decreased minute ventilation (MV) compared to those without IT. The proportion of datasets exhibiting IT was higher during PSV than in mandatory ventilation [83.8% (573/684) vs. 71.0% (237/334), P < 0.05], while, the prevalence of ITI ≥ 10% was lower [23.8% (163/684) vs. 33.5% (112/334), P < 0.05]. DT was detected in 305 datasets (30%), with a median incidence of 0.6% (0.4%, 1.3%). Datasets exhibiting DT were characterized by higher VT, reduced RR, and lower pressure support levels. The incidence of DT was lower in PSV compared to mandatory ventilation modes [0% (0%, 0.3%) vs. 0% (0%, 0.5%), P < 0.05]. The post-craniotomy for brain tumors group exhibited higher ITI, lower RR, reduced MV, and a greater proportion of infratentorial lesions, compared to the TBI group. The infratentorial lesion group demonstrated higher ITI and incidence of DT compared to the supratentorial lesion group [ITI: 3.1% (0.7%, 17.8%) vs. 1.5% (0%, 8.3%), incidence of DT: 0% (0%, 0.5%) vs. 0% (0%, 0%), both P < 0.05]. After adjusting for confounding factors through multivariate logistic regression analysis, infratentorial lesion [odds ratio (OR) = 2.029, 95% confidence interval (95%CI) was 1.465-2.811, P < 0.001], lower P_0.1 (OR = 0.714, 95%CI was 0.616-0.827, P < 0.001), and mandatory ventilation (OR = 1.613, 95%CI was 1.164-2.236, P = 0.004) were independently associated with IT. Additionally, infratentorial lesion (OR = 1.618, 95%CI was 1.213-2.157, P = 0.001), large tidal volume (OR = 1.222, 95%CI was 1.137-1.314, P < 0.001), lower pressure support levels (OR = 0.876, 95%CI was 0.829-0.925, P < 0.001), and mandatory ventilation (OR = 2.750, 95%CI was 1.983-3.814, P < 0.001) were independently associated with DT. CONCLUSION IT and DT were common in patients with acute brain injury. Infratentorial lesions and mandatory ventilation were independently associated with both IT and DT.
