OBJECTIVE To investigate the application status of prescription pre-review systems in healthcare institutions of Yunnan province， evaluate their system functions and management capabilities， and provide a practical basis for promoting rational drug use. METHODS A questionnaire survey was conducted among public healthcare institutions at or above the secondary level in Yunnan province to investigate the deployment status of the systems. A capability maturity assessment framework was constructed， encompassing 6 dimensions and 39 indicators， including real-time prescription review， prescription correlation review， rule setting， evidence-based information support， prescription authority management， and system operation management. This framework was then used to evaluate the institutions that had implemented the pre-review systems. RESULTS A total of 100 valid questionnaires were collected， with 37 institutions having adopted prescription pre-review systems， mainly tertiary hospitals. The system predominantly adopted a modular architecture and was embedded into the hospital information system through application programming interfaces and middleware， providing certain capabilities for real-time prescription risk identification. Evaluation results indicated that basic functions such as reviewing indications， contraindications， and drug compatibility performed well， while deficiencies remained in functions related to parenteral nutrition prescription， review of drug dosage for specific diseases， individual patient characteristic recognition， and rule setting. Moreover， the construction of review centers and establishment of management systems were also not well-developed. CONCLUSIONS The overall application rate of prescription pre-review systems in Yunnan province remains low. System functions and management mechanisms require further improvement. It is recommended to enhance information infrastructure in lower-level institutions and explore regionally unified review models to promote standardized and intelligent development of prescription review practices.

OBJECTIVE: To systematically search and integrate the best evidence for early rehabilitation of ICU-acquired swallowing dysfunction (ICU-ASD) using evidence-based medicine methods, providing high-quality evidence-based support for intensive care unit (ICU) healthcare professionals in implementing early rehabilitation assessment and intervention strategies for ICU-ASD. METHODS: The systematic search was conducted according to the "6S" pyramid evidence model. Multiple authoritative databases and resources were comprehensively searched, including: National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Canadian Medical Association Clinical Practice Guidelines Library (CMACPGL), New Zealand Guidelines Group (NZGG), Guidelines International Network (GIN), Registered Nurses' Association of Ontario (RNAO), Scottish Intercollegiate Guidelines Network (SIGN), PubMed/Medline, Cochrane Library, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, JBI Evidence-Based Health Care Database, Physiotherapy Evidence Database (PEDro), Chinese Medical Pulse Guidelines Website, SinoMed, CNKI, Wanfang Data, UpToDate, BMJ Best Practice, and professional association websites. The search encompassed guidelines, expert consensus statements, original studies [including cohort studies, quasi-experimental studies, and randomized controlled trials (RCT)], systematic reviews, and evidence summaries related to the prevention and management of ICU-ASD. The search period was limited from the inception of each database to November 30, 2024. The best evidence for early rehabilitation of ICU-ASD was summarized. The quality assessment of the literature and the extraction and synthesis of evidence were independently performed by two researchers with expertise in evidence-based medicine methodology. RESULTS: A total of 16 articles were included, consisting of 1 clinical decision-making study, 1 cohort study, 2 guidelines, 2 RCTs, 6 systematic reviews, 1 evidence summary, 2 expert consensuses, and 1 expert opinion. Following quality assessment, all 16 articles were incorporated into the analysis. For the early rehabilitation of ICU-ASD, five major themes were ultimately identified and 25 best evidence items were summarized, focusing on: multidisciplinary collaboration, swallowing screening and assessment, rehabilitation interventions, dietary and nutritional management, and oral hygiene. CONCLUSIONS The evidence summary provides individualized rehabilitation strategies for ICU-ASD patients, but their implementation still needs to be adapted to China's clinical practice context and patient preferences.

Objective To investigate the value of methyltransferase-like protein 16(METTL16)in the clinical di-agnosis and prognostic prediction of multiple myeloma(MM)patients.Methods The expression level and prog-nostic potential of each gene involved in N6-methyladenosine(m6A)modification in MM were respectively ana-lyzed in the databases of the Multiple Myeloma Research Foundation(MMRF)and the Genotype-Tissue Expression Project(GTEx).Bone marrow specimens from 26 patients with initial diagnosis of MM and 19 patients with MM af-ter treatment with standard regimens and peripheral blood specimens from 24 normal subjects were collected respec-tively,and the expression levels of m6A genes were determined by qRT-PCR.The correlation between METTL16 expression and various laboratory and clinical indexes was analyzed:hemoglobin(Hb),white blood cell count(WBC),platelet count(PLT),blood creatinine(Scr),serum calcium(Ca2+),β-microglobulin(β-MG),bone destruction,ISS stage,type,and overall survival(OS)in the patients with primary diagnosis.The expression lev-els of interleukin(IL)-4,IL-6,IL-10,IL-18 and chemokine ligand 2(CCL2),CCL3,CCL4 in the specimens were further examined and their correlation with the expression of METTL16 was investigated.Results Database a-nalysis suggested that METTL16 expression was significantly higher in MM patient samples compared with normal controls,which was associated with poor prognosis and had certain diagnostic value.qRT-PCR results showed that the expression level of METTL16 in the bone marrow of patients with initial diagnosis of MM was significantly higher than that of treated patients and normal controls.Its expression was positively correlated with hemoglobin,leuko-cytes and stage,and its expression was positively correlated with CCL4 expression.Conclusion METTL16 expres-sion was significantly elevated in patients with MM,and its expression level was correlated with anemia,more bone destruction and worse stage,which might indicate a poor prognosis.The significant correlation between the expres-sion of METTL16 and CCL4 suggests that METTL16 may play a corresponding pathogenic role through the relevant pathway.METTL16 will have significant clinical value in the management of MM.

Objective To explore the efficacy and technical points of complete preservation of female reproductive organ in radical cystectomy.Methods In 2020 and 2021,two female patients with bladder cancer undergoing radical cystectomy in The First Affiliated Hospital of Naval Medical University were selected.The clinical conditions of the patients were evaluated before surgery,and the reproductive organs were completely preserved according to the patients'wishes during the operation.The patients were regularly followed up after surgery.The efficacy and prognosis of patients were evaluated.Results The operation was successful and the two patients recovered well without surgery-related complications.The follow-up time for two patients were 22 months and 36 months.During the follow-up period,no tumor recurrence was found,and the scores of sexual function and quality of life were good.One patient was successfully pregnant at 17 months after surgery,and routine prenatal examination and non-invasive fetal DNA testing showed no abnormalities.Conclusions Under the premise of strictly grasping the surgical indications,the complete preservation of female reproductive organs in radical cystectomy can improve patients'quality of life after surgery,especially protect the reproductive function of women of childbearing age.

Objective To explore the correlation between hyponatremia at admission and all-cause mortality within one year after discharge in elderly patients with intestinal obstruction.Methods The 331 cases of elderly patients with intestinal obstruction(aged ≥ 60 years)who visited the General Surgery Department of Nanjing Meishan Hospital from January 2017 to December 2020 were selected as the research objects for retrospective cohort study analysis.According to the patient's blood sodium level at admission,they are divided into two groups:the hyponatremia group(Na＜135 mmol/L)and the non hyponatremia group(Na≥135 mmol/L).Divided into death group and survival group based on whether death occurred within one year after discharge.SPSS 25.0 software was used for statistical analysis.Independent sample t test,x2 test,Kaplan Meier method,and multivariate Cox regression analysis were used to observe the correlation between admission hyponatremia and all-cause mortality within one year after discharge in elderly patients with intestinal obstruction.Results A total of 331 patients were enrolled.The incidence of hyponatremia was 32.3％,and 56 deaths occurred within one year,accounting for 16.92％.The one-year mortality rate in the hyponatremia group was 23.4％(25/107),which was higher than 13.8％(31/224)in the non hyponatremia group.The difference was statistically significant(P＜0.05).The survival analysis(Kaplan Meier)results showed that the survival rate of the hyponatremia group was lower than that of the non hyponatremia group(Log Rank P＜0.05).After adjusting for other confounding factors in multivariate Cox regression analysis,hyponatremia(HR=1.88,95％CI:1.07-3.29)was an independent risk factor for one-year all-cause mortality in elderly patients with intestinal obstruction(P＜0.05).Conclusion Hyponatremia at admission is an independent risk factor for all cause mortality in elderly patients with intestinal obstruction within one year after discharge.

Objective:To investigate the establishment method, coordination points and safe transport management strategy of vena-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with downtime difficulties during cardiopulmonary bypass (CPB).Methods:A observation study was conducted. The patients admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to October 2022 were enrolled. These patients could not be separated from CPB and received VA-ECMO-assisted CPB surgery. The clinical data of the patients were recorded, including the basic information of the patients, the data of VA-ECMO establishment and transport process, the clinical indicators before and after VA-ECMO installation, the operation data of VA-ECMO and clinical outcomes. The experience was summarized from the aspects of extracorporeal membrane oxygenation (ECMO) establishment, transport process, team cooperation, and adverse events during transport. The clinical indicators before and after ECMO operation were compared. According to whether ECMO was successfully weaned, the patients were divided into a successful weaning group and a failure weaning group, and the clinical data between the two groups were compared.Results:Eighteen patients who underwent VA-ECMO-assisted CPB were enrolled, including 10 males and 8 females. The average age was (56.7±12.3) years old. Preoperative left ventricular ejection fraction (LVEF) was 0.46±0.10, and the main reasons for switching to VA-ECMO assistance included right ventricular systolic weakness in 6 cases, total cardiac systolic weakness in 5 cases, left ventricular systolic weakness in 4 cases, high pulmonary arterial pressure in 2 cases, and intractable ventricular fibrillation in 1 case. Among the 18 patients transferred from CPB to VA-ECMO, 10 cases were successfully weaned and 8 cases failed. In ICU, 8 cases survived, 5 cases died, and 5 cases gave up treatment and discharged. The average time for successful CPB to VA-ECMO establishment was (24.6±7.4) minutes, initial blood flow was (3.3±0.4) L/min, and transit time was (8.4±1.5) minutes. ECMO-assisted duration averaged (82.0±69.3) hours. Adverse events occurred in 9 patients during ECMO establishment and transfer. Post-ECMO onboarding for 4 hours, significant improvements were noted in blood lactic acid (Lac), pH value, mean arterial pressure (MAP), central venous oxygen saturation (ScvO 2) as compared with pre-ECMO onboarding [Lac (mmol/L): 10.5±7.0 vs. 15.2±6.8, pH value: 7.38±0.92 vs. 7.26±0.87, MAP (mmHg, 1 mmHg≈0.133 kPa): 74.9±13.7 vs. 58.4±17.0, ScvO 2: 0.678±0.065 vs. 0.611±0.061, all P < 0.01], and vasoactive-inotropic score (VIS) was also decreased (39.8±29.8 vs. 68.9±64.4, P < 0.01). Compared with successful weaning group, the patients in the failed weaning group exhibited higher pre-machine Lac (mmol/L: 18.8±7.8 vs. 12.3±4.3, P < 0.05), longer CPB time [minutes: 238.0 (208.8, 351.2) vs. 200.0 (185.8, 217.0), P < 0.05], and shorter ECMO-assisted time [hours: 19.5 (11.0, 58.8) vs. 94.5 (65.8, 179.8), P < 0.01]. However, there was no statistically significant difference in pre-machine pH value, ScvO 2, MAP, VIS score, and initial blood flow and establishment time of ECMO between the two groups. Conclusions:VA-ECMO is an effective circulatory aid for CPB surgery that cannot be weaned after CPB. The establishment and transfer of CPB "bridge" to ECMO aid depends on multi-disciplinary treatment (MDT) cooperation. The success rate of ECMO weaning is related to the Lac and CPB duration. If it is not possible to detach from the CPB successfully, VA-ECMO should be initiated as early as possible.

Objective:To investigate the value of mean platelet volume-to-lymphocyte ratio (MPVLR) in assessing the prognosis of elderly patients treated with radiotherapy for esophageal cancer.Methods:A retrospective case series study was conducted. The clinical data of 102 elderly esophageal cancer patients who received radiotherapy from September 2015 to September 2020 in Zhongshan Hospital Affiliated to Xiamen University were retrospectively analyzed. After admission, all patients were tested for serum mean platelet volume and lymphocyte levels by using a fully automated hematology analyzer, and MPVLR was calculated. The optimal cut-off value of MPVLR was determined based on the receiver operating characteristic (ROC) curve. The patients were grouped according to the optimal cut-off value of MPVLR, and clinicopathological characteristics of the two groups were compared. The Kaplan-Meier method was used to analyze the overall survival of patients after radiotherapy, and the multivariate Cox proportional risk model was used to analyze the factors affecting the overall survival of patients after radiotherapy.Results:The age of 102 patients was (77±3) years; there were 58 male cases, 44 female cases; 67 cases of middle and high differentiation, 35 cases of low differentiation; 65 cases of TNM stage Ⅰ-Ⅱ, 37 cases of stage Ⅲ-Ⅳ. ROC curve analysis showed that the area under the curve of MPVLR predicting the overall survival of esophageal cancer patients after radiotherapy was 0.905 (95% CI: 0.855-0.955). The optimal cut-off value of MPVLR was 5.442. All patients were divided into the low MPVLR group (MPVLR ≤ 5.442, 60 cases) and the high MPVLR group (MPVLR > 5.442, 42 cases) according to the optimal cut-off value of MPVLR. The proportion of patients with low differentiation and stage Ⅲ-Ⅳ in the high MPVLR group was higher than that in the low MPVLR group (all P < 0.001). The 3-year overall survival rate after radiotherapy in the high-MPVLR group was lower than that in the low-MPVLR group (23.81% vs. 51.67%), and the difference in the overall survival of both groups was statistically significant ( P < 0.05). The differences in the overall survival of elderly esophageal cancer patients with different differentiation and TNM staging after radiotherapy were statistically significant (all P < 0.05). Univariate Cox regression analysis showed that TNM stage Ⅲ-Ⅳ ( HR = 3.034, 95% CI: 1.805-5.101), low differentiation ( HR = 2.872, 95% CI: 1.791-4.606), and MPVLR > 5.442 ( HR = 3.789, 95% CI: 2.000-7.178) were independent risk factors for overall survival in elderly patients with esophageal cancer after radiotherapy (all P < 0.001). Conclusions:MPVLR before radiotherapy is closely related to the prognosis of elderly patients with esophageal cancer, and patients with MPVLR > 5.442 may have poorer overall survival after radiotherapy.

Objective:To investigate the expressions of Nod-like receptor protein 3 (NLRP3), cysteine-aspartic acid protease 1 (Caspase-1), and Gasdermin D (GSDMD) in nasopharyngeal carcinoma (NPC), and their relationships with the recurrence and metastasis of NPC.Methods:A retrospective study was conducted on 421 patients diagnosed with NPC between December 2014 and January 2020. The expressions of NLRP3, Caspase-1, and GSDMD in pathological specimens were examined with immunohistochemistry and multiplex immunofluorescence staining. Univariate and multivariate Cox regression analyses were applied to identify the factors influencing NPC recurrence and metastasis. In vitro experiments with NPC cell line HNE-2 were used to explore the functional mechanisms of NLRP3, Caspase-1, and GSDMD.Results:Multivariate Cox analysis revealed that tumor staging of Ⅲ-Ⅳ( HRrecurrence=2.74, 95% CIrecurrence: 1.61-4.65; HRmetastasis=1.90, 95% CImetastasis: 1.04-3.49) and pre-treatment plasma EBV-DNA levels≥1 500 copies/ml ( HRrecurrence=1.91, 95% CIrecurrence: 1.13-3.23; HRmetastasis=2.07, 95% CImetastasis: 1.23-3.50)were independent risk factors for NPC recurrence and metastasis, while positive expression of NLRP3( HRrecurrence=0.17, 95% CIrecurrence: 0.08-0.35; HRmetastasis=0.30, 95% CImetastasis: 0.15-0.59), Caspase-1( HRrecurrence=0.32, 95% CIrecurrence: 0.18-0.59; HRmetastasis=0.43, 95% CImetastasis: 0.25-0.76), and GSDMD( HRrecurrence=0.48, 95% CIrecurrence: 0.25-0.91; HRmetastasis=0.96, 95% CImetastasis: 0.53-1.74) served as independent protective factors. Age ( HR=1.02, 95% CI: 1.01-1.04) and intensity-modulated radiotherapy ( HR=0.51, 95% CI: 0.30-0.88) were independent factors for NPC recurrence, whereas chemotherapy ( HR=0.50, 95% CI: 0.29-0.88) acted as an independent protective factor for NPC metastasis (all P<0.05). NPC patients with positive expressions of the three proteins had higher locoregional recurrence-free survival, distant metastasis-free survival, and overall survival compared to those with negative expressions (all P<0.05). In vitro experiments revealed that the overexpression of NLRP3 activated the NLRP3/Caspase-1/GSDMD signaling pathway, as evidenced by Western Blot analysis. Enzyme-linked immunosorbent assay and scanning electron microscopy demonstrated that overexpression of NLRP3 promoted pyroptosis in HNE-2 cells. Cellular functional assays further confirmed that overexpression of NLRP3 significantly inhibited the proliferation, invasion, and migration of HNE-2 cells. Conclusion:Positive expressions of NLRP3, Caspase-1, and GSDMD serves as independent protective factors for recurrence and metastasis of NPC, potentially by promoting cell pyroptosis and thus inhibiting NPC cell proliferation, invasion, and migration.

Objective:To explore the clinical efficacy of a retrograde pubic ramus intramedullary nail (RPRIN) in the treatment of anterior pelvic ring fractures.Methods:A retrospective study was conducted to analyze the 14 patients with anterior pelvic ring fracture who had been treated and followed up at Department of Traumatic Surgery, Tongji Hospital From June 2020 to February 2021. There were 10 males and 4 females with an age of (44.8±12.5) years. By the AO/OTA classification for pelvic fractures, 5 cases were type 61-A, 4 cases 61-B, and 5 cases type 61-C; by the Nakatani classification, 1 case belonged to unilateral zone Ⅰ fracture, 5 cases to unilateral zone Ⅱ fracture, 2 cases to unilateral zone Ⅲ fracture, 3 cases to right zone Ⅱ and left zone Ⅲ fracture, 2 cases to zone Ⅲ fracture on both left and right sides, and 1 case to zone Ⅱ fracture on both sides. The time from injury to operation was (7.8±1.8) days. All the anterior pelvic ring fractures were fixated with a RPRIN. The time and fluoroscopic frequency for placement of every single RPRIN, quality of fracture reduction, and pelvic function and incidence of postoperative complications at the last follow-up were recorded.Results:A total of 18 RPRINs were placed in the 14 patients. For placement of each RPRIN, the time was (35.9±8.6) min, and the fluoroscopic frequency (22.8±1.9) times. No complications such as infection occurred at any surgical incision after RPRIN placement. According to the Matta scoring, the quality of postoperative fracture reduction was assessed as excellent in 7 cases, as good in 5 cases and as fair in 2 cases. The 14 patients were followed up for (18.1+1.5) months. Their X-ray and CT images of the pelvis at the last follow-up showed that the fractures healed well and the intramedullary nails were placed in the cortical bone of the anterior ring of the pelvis. According to the Majeed scoring at the last follow-up, the pelvic function was assessed as excellent in 10 cases, as good in 3 cases and as fair in 1 case. One patient reported discomfort during squatting 2 months after operation but the symptom improved 3 months later without any special treatment. No patient experienced such complications as displacement or slippage of RPRIN, or pain at the insertion site.Conclusion:RPRIN is effective in the treatment of anterior pelvic ring fractures, showing advantages of small surgical incision, limited intraoperative fluoroscopy and short operation time.

Femoral head fracture is commonly seen in high-energy injury. However, compression fracture of femoral head is more rare. In most classifications of femoral head fracture, the compression is unusually involved. A case about acute traumatic dislocation of hip joint with compression fracture of femoral head is reported, involving a patient who hurt himself by riding electric bike and hitting the flower bed. He came to our hospital complaining of pain and limited motion of his right leg. The diagnosis of right hip anterior dislocation with the compression fracture of femoral head was confirmed by medical history, physical examination and imaging. Closed reduction of hip dislocation was performed in an emergency. Then we transplanted the bone cartilage from the non-weight-bearing area under the femoral head to the collapsed weight-bearing area, fixing it with countersunk hollow screws, and then the non-weight-bearing donor area was reconstructed with autogenous iliac bone, using surgical hip dislocation. The anatomical structure of the femoral head was therefore restored successfully during the operation. Three months after surgery, the X-ray showed that the femoral head was smooth and the cartilage graft was well fixed. Eight months after surgery, the patient gradually increased the bearing weight from partial to full according to his own condition, and there was no obvious pain in hip. After 24-month follow-up, we found the X-rays showed good reduction and fixation of the femoral head fracture. The CT scan showed no necrosis or cystic degeneration. He got well-active and passive movement in hip joint, and got no pain when walking with burden. For the patient with hip dislocation and compression fracture of femoral head, early joint reduction and non-weight-bearing osteocartilage transplantation can restore the anatomical structure of the weight-bearing area of the femoral head, to avoid traumatic osteoarthritis, and to improve the long-term quality of life of patients.
