OBJECTIVE To explore the effects of prescription pre-review system on rational drug use and off-label drug use management in outpatient and emergency department. METHODS A retrospective analysis was conducted on outpatient and emergency department prescription data from three phases in our hospital： January to May 2023 （silent review phase， control group）， June to October 2023 （systematic automatic review phase， intervention group 1）， and November 2023 to March 2024 （phase combining systematic automatic review with centralized feedback from pharmacists to physicians regarding irrational prescriptions， intervention group 2）. These phases followed the implementation of our hospital’s pre-prescription review software. Statistical analysis of the prompt rate of alert， rate of irrational prescriptions， registered the off-label drug use rate and false positive irrationality prescription rate were conducted. Meanwhile， the composition of irrational prescriptions was analyzed， and evidence- based evaluation of the off-label drug use proposed by clinicians was also conducted. RESULTS Compared with control group， the prompt rate of alert and the rate of irrational prescriptions in intervention group 1 were all decreased significantly after receiving pop-up notification， with statistically significant differences （P＜0.05）. With the help of system warning and the pharmacists feedback， the prompt rate of alert and the rate of irrational prescriptions declined further in the intervention group 2， but there was no statistically significant difference when compared with intervention group 1 （P＞0.05）. The main type of irrational drug use was improper administration routes. When comparing intervention group 1 with the control group， as well as intervention group 2 with intervention group 1， a significant decrease in the rate of improper administration routes was observed， with statistically significant differences （P＜0.05）. Compared with control group， there was no significant difference in the registered off-label drug use rate of intervention group 1 and intervention group 2 （P＞0.05）. The doctor’s awareness of off-label drug use registration increased due to the real-time alerts from the pre-prescription review software， along with the pharmacists’ regular summarization and feedback. Total 13 items registrations of off-label drug use were proposed by clinicians from June 2023 to March 2024， all of which were supported by evidence of varying levels； among them， 3 items received FDA approval， 4 items were included in the Micromedex database， and the remaining 6 items were supported by evidence from system reviews or randomized controlled trials. CONCLUSIONS Prescription pre-review system can improve the level of rational drug use and assist in the standardized management of off-label drug use.

Objective:To test the validity and reliability of the Chinese version of the Pre-sleep Arousal Scale(PSAS)in patients with brief insomnia disorder(BID).Methods:Totally 170 patients with BID and 150 normal sleepers(NS)were recruited.All participants were assessed with the PSAS,Hospital Anxiety and Depression Scale(HADS)and Insomnia Severity Index(ISI).After 3 months,72 patients with BID were retested with the PSAS,HADS and ISI.Results:The PSAS scores of BID group were characteristic of a normal distribution.The PSAS total scores were positively correlated with the scores of HADS and ISI(r=0.55,0.40,Ps＜0.01).Two factors of so-matic and cognitive arousal were extracted in PSAS by the exploratory factor analysis and parallel analysis,interval variance value was 55.84％,and the load scores of items were 0.46-0.89.The scores of PSAS and its subscales were higher in the BID group than in the NS group(Ps＜0.001).The best cut-off score for the overall PSAS was found at 32/33 and had high sensitivity(0.72)and specificity(0.81).The Cronbach's α coefficient and the Spearman Brown split reliability were 0.91 and 0.76,respectively,the correlation coefficients between the items and total score ranged from 0.46 to 0.89(Ps＜0.01),and the test-retest reliability was 0.37(P＜0.01).Addi-tionally,rate of change of PSAS scores was positively correlated with the rate of change of HADS scores and ISI scores(Ps＜0.05).Conclusion:The Chinese version of PSAS is a reliable and valid instrument to assess pre-sleep arousal in patients with brief insomnia disorder.

Objective:To explore the clinical characteristics and molecular basis for children and adolescents with monogenic diabetes.Methods:A retrospective analysis was carried out for the clinical manifestations and laboratory data of 116 children and adolescents diagnosed with diabetes at Ningbo Women and Children′s Hospital from January 2020 to March 2023. Whole exome sequencing and mitochondrial gene sequencing were carried out on 21 children with suspected monogenic diabetes.Results:A total of 10 cases of monogenic diabetes were diagnosed, all of which were Maturity-onset Diabetes Of the Young (MODY). Six cases of MODY2 were due to GCK gene mutations, 1 case of MODY3 was due to HNF1A gene mutation, 2 cases of MODY12 were due to ABCC8 gene mutations, and 1 case of MODY13 was due to KCNJ11 gene mutation. Nine of the 10 patients with MODY had no typical symptoms of diabetes. A family history of diabetes was significantly more common in the MODY group compared with the T1DM and T2DM groups ( P<0.05). The BMI of the MODY group was higher than that of the T1DM group ( P<0.05). The initial blood glucose level was lower than that of the T1DM group ( P<0.05), and there was no significant difference compared with the T2DM group. The fasting C-peptide level of the MODY group was higher than that of the T1DM group ( P<0.05), and there was no significant difference compared with the T2DM group. Glycosylated hemoglobin of the MODY group was lower than both the T1DM and T2DM groups ( P<0.05). Conclusion:In this study, MODY has accounted for the majority of monogenic diabetes among children and adolescents, and the common mutations were those of the GCK gene in association with MODY2. Blood glucose and glycosylated hemoglobin of children with MODY were slightly increased, whilst the islet cell function had remained, and the clinical manifestations and laboratory tests had overlapped with those of type 2 diabetes. WES and mitochondrial gene sequencing can clarify the etiology of monogenic diabetes and facilitate precise treatment.

Wound infections, secondary to acute and chronic wounds caused by mechanical, thermal, chemical factors, etc, not only delay wound healing but also may lead to mortality. The prolonged or inappropriate use of antibiotics lead to the growth of drug-resistant bacteria, resulting in refractory wound infections and poor treatment outcomes, which highlights the urgent need for effective therapies. Bacteriophages show great promise in treating drug-resistant wound infections due to their effectiveness in killing drug-resistant bacteria, their good resistance against bacterial biofilm (BBF) and their absence of cytotoxicity to eukaryotic cells. However, the mechanisms underlying bacteriophages′ resistance against BBF remain incompletely understood and their antibacterial efficacy for wound infections may also vary. For this purpose, the authors reviewed the biological characteristics and mechanisms of bacteriophages and their application in antibacterial therapies for wound infections, aiming to provide a reference for further research and application of bacteriophages in the treatment of wound infections.

Objective:To explore the feasibility of using quantitative parameters of double contrast-enhanced ultrasound (DCUS) to noninvasively predict lymphatic metastasis in gastric cancer before operation.Methods:From December 2021 to October 2023, 119 patients undergoing gastrectomy at the Second Hospital & Clinical Medical School, Lanzhou University, were enrolled retrospectively. Based on the pathological findings, they were divided into lymph node metastasis (N1, 94 cases) and non-lymph node metastasis (N0, 25 cases) groups. All patients underwent DCUS within 3 days before surgery. Previous to DCUS, lesions′ location and ultrasonic T-staging were recorded by conventional ultrasound. Quantitative parameters such as arrival time (AT), time to peak (TTP), baseline intensity (BI), peak intensity (PI) and wash-in slope (WIS) were obtained by the time-intensity curve (TIC) automatically, and then manually calculated enhanced intensity (ΔPI=PI–BI) and enhanced time (ΔTTP=TTP–AT). Binary Logistic regression analysis was used to screen independent risk factors for predicting lymph nodes metastasis in gastric cancer, and regression models were established.Results:Statistical tests revealed significant differences in ultrasonic T-staging ( P<0.001) and degree of differentiation ( P=0.015) between N1 and N0 group. Among DCUS quantitative parameters, statistical differences in PI, ΔPI and WIS were observed between the two groups (all P<0.05), while no significant differences were found in BI, AT, TTP and ΔTTP (all P>0.05). Logistic regression analysis showed that ultrasonic T-staging and WIS were independent risk factors for predicting lymphatic metastasis. The regression model built on the above two factors performed well in predicting lymph nodes metastasis, with an area under the curve of 0.905, accuracy of 93.3% (superior to the prediction model based on DCUS quantitative parameters alone, P<0.05), sensitivity of 95.7% and specificity of 84.0%. Conclusions:DCUS quantitative parameters may be helpful to evaluate lymphatic metastasis of gastric cancer prior to surgery, and the accuracy of prediction would be improved by combing with ultrasonic T-staging.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

Purpose To explore the association of tumor budding in preoperative biopsies with the clinicopathological characteristics of colorectal cancer(CRC),and its effects on the prognosis.Methods A total of 144 preoperative biopsies and corresponding radical resection specimens of colorectal ade-nocarcinoma were collected.Tumor budding was evaluated by HE staining and EnVision immunohistochemical staining,to an-alyze the association of tumor budding with the clinicopathologi-cal characteristics and prognosis in biopsies.Results The de-tection rate of intra-tumoral budding(ITB)in biopsy specimens was 39.6%(57/144),and peritumoural budding(PTB)in surgical specimens was 64.6%(93/144);ITB was significantly correlated with PTB(r =0.510,P<0.05).The proportion of patients with lymph node metastasis,pTNM stage,differentiated degree,vascular invasion and nerve recidivism in the tumor bud-ding group of biopsies was significantly higher than that in no tumor budding group(P<0.05).Kaplan-Meier survival analy-sis showed that ITB significantly affected the overall survival and progression free survival of CRC(P<0.05).Conclusion The presence of ITB in biopsies tissue may be an important indicator of invasive behavior and poor prognosis in CRC.

Objective:To investigate the effect of helicobacter pylori (HP) infection and eradication treatment on small intestinal bacterial overgrowth (SIBO) in children.Methods:A prospective case-control study was conducted to select 68 children with symptoms of abdominal distension, abdominal pain, diarrhea and suspected digestive system diseases admitted to the Affiliated Hospital of Xuzhou Medical University from June 2021 to June 2022. They were divided into HP negative group and HP positive group according to HP infection. HP positive group received triple standardized HP eradication treatment, 14 days as a course of treatment. The baseline SIBO positive rate and gastrointestinal symptom rating scale (GSRS) score of the two groups were compared. The HP positive group was followed up for 4 and 12 weeks after drug withdrawal for quantitative assessment of gastrointestinal symptoms and LHBT. The SIBO positive rate, GSRS score of the two groups and the change of SIBO positive rate and GSRS score of the HP positive group before and after treatment were compared. The measurement data with normal distribution were expressed, and independent sample t-test was used for comparison between the two groups. M( Q1, Q3) was used to represent the measurement data of non normal distribution, and Mann Whitney U test was used to compare the two groups; Friedman test was used for comparison between multiple time points, and Nemenyi test was used for pairwise comparison. Four grid table or paired χ 2 test was used to compare the counting data between groups. Results:The positive rate of SIBO in HP negative group was lower than that in HP positive group (36.1% (13/36) vs 62.5% (20/32)), the difference was statistically significant (χ 2=4.72, P=0.030). Four weeks after drug withdrawal, the SIBO positive rate in HP positive group was higher than that before treatment (87.5% (28/32) vs 62.5% (20/32)), and 12 weeks after drug withdrawal was lower than that before treatment (21.9% (7/32) vs 62.5% (20/32)), with statistically significant differences (χ 2=8.00, P=0.008; χ 2=13.00, P<0.001). There was no statistically significant difference in GSRS score between HP negative group and HP positive group ( P=0.098). The clinical symptoms of 32 children in HP positive group were improved 4 and 12 weeks after HP eradication was stopped. GSRS scores were lower than those before treatment (8.0 (6.0, 12.8), 7.0 (5.0, 9.0) points vs 15.0 (12.0, 19.0) points) , and the differences were statistically significant ( Z values were -3.91, -4.68, respectively; all P<0.001). Conclusions:HP infection can increase the positive rate of SIBO in children with suspected digestive system diseases. The standardized triple HP eradication therapy may further aggravate the overgrowth of intestinal bacteria while treating HP infection, but this effect can be eliminated after 12 weeks of treatment.
