Many species of the genus Asarum plants are used as Chinese traditional or folk medicines, in Chinese which are known as "Xixin" (Asari Radix et Rhizoma) , "Bei-Xixin" , "Hua-Xixin" and "Nan-Xixin" , etc. In order to get a clear picture of resources distribution and varieties on Chinese markets of the crude drug Xixin and provide scientific basis for their resource conservation and sustainable use, during recent years we conducted field investigations and market researches many times. The results showed that the resources of both official Xixins and non-official Xixins were decreased because of the ecological environment damage and over-digging, especially species whose population size was small. Bei-Xixin derived from A. heterotropoides var. mandshuricum was the most species on the Chinese markets except for a few areas of China. Hua-Xixin derived from A. sieboldii and non-official Xixins were mainly used in their producing areas. Cultivation of Hua-Xixin should be greatly developed, and wild resources of non-official species must be preserved strictly.

OBJECTIVETo explore the effects of the method of soothing the liver and regulating qi on expression of gastrin and somatostatin in hypothalamus and gastric antrum of functional dyspepsia model rats.
METHODThe 32 rats were randomly divided into normal group, model group, Chaihu Shugansan group and domperidone group (n = 8). The functional dyspepsia model was established by constantly squeezing their tails and mean while saline, Chaihu Shugansan decoction and domperidone suspension were administered respectively to 4 groups by gavage. The expression of gastrin and somatostatin in hypothalamus and gastric antrum of rats by immunohistochemical were detected 3 weeks later.
RESULTThe expression of GAS in the hypothalamus and gastric antrum of model group were less than those of normal group (P < 0.05, P < 0.01), while the expression of SS in the hypothalamus and gastric antrum in Model group were significantly increased than those of normal group (P < 0.01). The expression of GAS and SS in gastric antrum of Chaihu Shugansan group and domperidone group were increased and decreased respectively, and the differences were significant (P < 0.05, P < 0.01). There were no obvious difference about expression of GAS, SS in the hypothalamus between domperidone group and model group. GAS expression in hypothalamus of Chaihu Shugansan group were increased than those of normal group but there was no obvious difference in SS expression in hypothalamus between Chaihu Shugansan group and model group.
CONCLUSIONThe method of soothing the liver and regulating qi can increase GAS expression in central and peripheral and decrease SS expression in peripheral gastric antrum, which may be one of its therapeutic mechanisms on functional dyspepsia.

Objective To explore the feasibility and application value of sonography in the evaluation of oropharynx in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods The oropharynx of forty-four patients with OSAHS and forty-four healthy subjects selected as the control group were separately examined by ultrasonography.The parameters including anterior-posterior diameter and the lateral diameter of oropharyngeal airway of the end-deep inspiratory and end-deep expiratory,thickness and wide of tongue base,lingual wide,lingual height,distance from mandibular plane to hyoid bone and distance from tongue base to mandibular plane were obtained for statistical analysis and compared between the two groups.Correlation analysis of above parameters plane with body mass index (BMI) were carried out. Results The anatomy of the oropharynx was well shown on sonography.When compared with the control group,the lateral diameter of oropharyngeal airway,thickness of tongue base,lingual height,lingual wide and distance from mandibular plane to hyoid bone also showed significant statistically differences between the OSAHS patients group and the control group (all P <0.01).The wide of tongue base,thickness of tongue base,lingual wide,lingual height,distance from mandibular plane to hyoid bone,and distance from tongue base to mandibular plane in OSAHS patients group were positively correlated with BMI( r =0.533,0.415, 0.555,0.349,0.378,0.419;all P <0.05).The wide of tongue base and lateral diameter of oropharyngeal airway in the control group were negatively correlated with BMI ( r = -0.324,-0.405,-0.317;all P <0.05).Conclusions Ultrasonography can be used to assist in the assessment of OSAHS,which can provide an important reference for clinical diagnosis and therapeutic effect evaluation of OSAHS.

Objective To establish an early prediction model for the diagnosis of severe acute pancreatitis based on the improved machine learning models,and to analyze its clinical value.Methods A case-control study was conducted on 352 patients with acute pancreatitis admitted to the Gastroenterology and Hepatobiliary Surgery Departments of the Army Medical Center of PLA and Emergency and Critical Care Medicine Department of No.945 Hospital of Joint Logistics Support Force of PLA from January 2014 to August 2023.According to the severity of the disease,the patients were divided into the severe group(n=88)and the non-severe group(n=264).The RUSBoost model and improved Archimead optimization algorithm was used to analyze 39 routine laboratory biochemical indicators within 48 h after admission to construct an early diagnosis and prediction model for severe acute pancreatitis.The task of feature screening and hyperparameter optimization was completed simultaneously.The ReliefF algorithm feature importance rank and multivariate logistic analysis were used to analyze the value of the selected features.Results In the training set,the area under curve(AUC)of the improved machine learning model was 0.922.In the testing set,the AUC of the improved machine learning model reached 0.888.The 4 key features of predicting severe acute pancreatitis based on the improved Archimedes optimization algorithm were C-reactive protein,blood chlorine,blood magnesium and fibrinogen level,which were consistent with the results of ReliefF algorithm feature importance ranking and multivariate logistic analysis.Conclusion The application of improved machine learning model analyzing the laboratory examination results can help to early predict the occurrence of severe acute pancreatitis.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

A novel coronavirus pneumonia (NCP) epidemic has occurred in Wuhan, Hubei Province since December 2019, caused by a novel coronavirus (2019-nCoV) never been seen previously in human. China has imposed the strictest quarantine and closed management measures in history to control the spreading of the disease. However, severe trauma can still occur in the NCP patients. In order to standardize the emergency treatment and the infection prevention and control of severe trauma patients with hidden infection, suspected or confirmed infection of 2019-nCoV, Trauma Surgery Branch of Chinese Medical Doctors' Association organized this expert consensus. The consensus illustrated the classification of the NCP patients, severe trauma patients in need of emergency surgery, emergency surgery type, hierarchical protection for medical personnel and treatment places. Meanwhile, the consensus standardized the screening, injury severity evaluation, emergency surgical treatment strategy and postoperative management strategy of severe trauma patients during the epidemic period of NCP, providing a basis for the clinical treatment of such kind of patients.
