Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background/Aims: Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients. Methods: We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development. Results: Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients. Conclusions Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

The bacterial ATP-competitive GyrB/ParE subunits of type II topoisomerase are important anti-bacterial targets to treat super drug-resistant bacterial infections. Herein we discovered novel pyrrolamide-type GyrB/ParE inhibitors based on the structural modifications of the candidate AZD5099 that was withdrawn from the clinical trials due to safety liabilities such as mitochondrial toxicity. The hydroxyisopropyl pyridazine compound 28 had a significant inhibitory effect on Gyrase (GyrB, IC₅₀ = 49 nmol/L) and a modest inhibitory effect on Topo IV (ParE, IC₅₀ = 1.513 μmol/L) of Staphylococcus aureus. It also had significant antibacterial activities on susceptible and resistant Gram-positive bacteria with a minimum inhibitory concentration (MIC) of less than 0.03 μg/mL, which showed a time-dependent bactericidal effect and low frequencies of spontaneous resistance against S. aureus. Compound 28 had better protective effects than the positive control drugs such as DS-2969 ( 5) and AZD5099 ( 6) in mouse models of sepsis induced by methicillin-resistant Staphylococcus aureus (MRSA) infection. It also showed better bactericidal activities than clinically used vancomycin in the mouse thigh MRSA infection models. Moreover, compound 28 has much lower mitochondrial toxicity than AZD5099 ( 6) as well as excellent therapeutic indexes and pharmacokinetic properties. At present, compound 28 has been evaluated as a pre-clinical drug candidate for the treatment of drug-resistant Gram-positive bacterial infection. On the other hand, compound 28 also has good inhibitory activities against stubborn Gram-negative bacteria such as Escherichia coli (MIC = 1 μg/mL), which is comparable with the most potent pyrrolamide-type GyrB/ParE inhibitors reported recently. In addition, the structure-activity relationships of the compounds were also studied.

Objective:To explore the reference ranges and influential factors of disturbance coefficient (DC) in children without craniocerebral injury at different ages.Methods:Two hundred children without craniocerebral injury admitted to the Department of Orthopaedics in Children′s Hospital of Chongqing Medical University from May 2018 to October 2019 were enrolled in this prospective study. The children were divided into four groups according to age, 0-1 year, >1-3 years, >3-5 years and >5-16 years, each of which included 50 children. Each child had DC measured twice with the non-invasive dynamic cerebral edema monitor, and the average value was used as the terminal DC value. Each measurement lasted 15 minutes, 12 hours apart. The difference of DC values among the four groups and between different genders were compared with ANOVA test and nonparametric test. And the Loess local weighted nonparametric regression analysis was used to explore the change of DC according to the increase of age, weight and head circumference (HC).Results:The reference values of DC for children of 0-1 year,>1-3 years, >3-5 years, and >5-16 years were 60±14, 92±18, 112±18, 135±18, respectively ( F=175.690, P<0.01). There was no statistical significance in DC between male and female children either in the whole or in each separate age group (103 (81, 125) vs. 102 (68, 123) , Z=-0.739, P=0.460; 59 (52, 68) vs. 57 (53, 65) , Z=-0.243, P=0.808; 88 (81, 105) vs. 95 (70, 105) , Z=-0.776, P=0.437; 117 (99, 120) vs. 113 (101, 123) , Z=-0.170, P=0.865; 137 (123, 143) vs. 142 (123, 160) , Z=-1.279, P=0.201). When the child′s age was younger than 5 years, weight was less than 18 kg or HC was less than 51 cm, the DC increased significantly with the increase of age, weight or HC. However, when the age, weight and HC were over the above values, the DC did not show obvious increase, but approaching to stable values of 135, 130, and 130, respectively. Conclusions:For children without craniocerebral injury, the reference values of DC are obviously different at different ages. DC is positively related to age, weight and HC, but not related to gender.

OBJECTIVE: To train convolutional networks using multi-lead ECG data and classify new data accurately to provide reliable information for clinical diagnosis. METHODS: The data were pre-processed with a bandpass filter, and signal framing was adopted to adjust the data of different lengths to the same size to facilitate network training and prediction. The dataset was expanded by increasing the sample size to improve the detection rate of abnormal samples. A depth-wise separable convolution structure was used for more specific feature extraction for different channels of twelve-lead ECG data. We trained the two classifiers for each label using the improved DenseNet to classify different labels. RESULTS: The propose model showed an accuracy of 80.13% for distinguishing between normal and abnormal ECG with a sensitivity of 80.38%, a specificity of 79.91% and a F1 score of 79.35%. CONCLUSIONS The model proposed herein can rapidly and effectively classify the ECG data. The running time of a single dataset on GPU is 33.59 ms, which allows real-time prediction to meet the clinical requirements.

【Objective】To investigate the differences of lung involvement between dengue and severe dengue.【Methods】227 dengue patients admitted in The Third Affiliated Hospital of Sun Yat-sen University from July 2014 to October 2018 were enrolled. The clinical characteristics，treatment and outcome of the patients were analyzed to explore the differences of lung involvement between dengue and severe dengue （SD）. 【Results】 The rate of old age ，smoking ，hypertension，diabetes and cerebrovascular disease was higher in dengue with lung involvement group（DWLI）than dengue without lung involvement group（DWOLI）（χ2 were 25.146，3.847，10.326，7.177，and 5.355，P was 0.050 for smoking，the others were < 0.05）. The rate of cough and breathlessness was higher in DWLI（χ2 were 11.465 and 6.068，P were 0.001 and 0.014），as well as in SD subgroup（χ2 were 4.585 and 6.717，P were 0.032 and 0.010）. C-reactive protein and procalcitonin were increased in DWLI（Z were - 2.591 and - 3.033，P were 0.010 and 0.002）. The rate of pleural effusion was higher in SD subgroup（χ2 = 4.987，P = 0.026）. Bilateral lung infiltration was correlated with SD（χ2 = 5.910，P =0.015）. The rate of acute liver injury，acute kidney injury and multi-organ dysfunction syndrome（MODS）was higher in DWLI（χ2 were 7.044，7.059，and 11.315，P were 0.008，0.008 and 0.001）. The rate of anti-virus，anti-bacteria and combined therapy was higher in DWLI（χ2 were 13.156，32.845，and 12.684，P all were < 0.001）.【Conclusion】Dengue patients who were with old age，smoking，or suffered from underlying disease of hypertension，diabetes and cerebrovascular disease were vulnerable to lung involvement. Cough，breathlessness，pleural effusion and bilateral lung infiltration were signs of severe dengue. Attention should be paid to dengue with lung involvement.
