Obstructive sleep apnea (OSA) is an increasingly widespread sleep-breathing disordered disease, and is an independent risk factor for many high-risk chronic diseases such as hypertension, coronary heart disease, stroke, arrhythmias and diabetes, which is potentially fatal. The key to the prevention and treatment of OSA is early diagnosis and treatment, so the assessment and diagnostic technologies of OSA have become a research hotspot. This paper reviews the research progresses of severity assessment parameters and diagnostic technologies of OSA, and discusses their future development trends. In terms of severity assessment parameters of OSA, apnea hypopnea index (AHI), as the gold standard, together with the percentage of duration of apnea hypopnea (AH%), lowest oxygen saturation (LSpO₂), heart rate variability (HRV), oxygen desaturation index (ODI) and the emerging biomarkers, constitute a multi-dimensional evaluation system. Specifically, the AHI, which measures the frequency of sleep respiratory events per hour, does not fully reflect the patients’ overall sleep quality or the extent of their daytime functional impairments. To address this limitation, the AH%, which measures the proportion of the entire sleep cycle affected by apneas and hypopneas, deepens our understanding of the impact on sleep quality. The LSpO₂ plays a critical role in highlighting the potential severe hypoxic episodes during sleep, while the HRV offers a different perspective by analyzing the fluctuations in heart rate thereby revealing the activity of the autonomic nervous system. The ODI provides a direct and objective measure of patients’ nocturnal oxygenation stability by calculating the number of desaturation events per hour, and the biomarkers offers novel insights into the diagnosis and management of OSA, and fosters the development of more precise and tailored OSA therapeutic strategies. In terms of diagnostic techniques of OSA, the standardized questionnaire and Epworth sleepiness scale (ESS) is a simple and effective method for preliminary screening of OSA, and the polysomnography (PSG) which is based on recording multiple physiological signals stands for gold standard, but it has limitations of complex operations, high costs and inconvenience. As a convenient alternative, the home sleep apnea testing (HSAT) allows patients to monitor their sleep with simplified equipment in the comfort of their own homes, and the cardiopulmonary coupling (CPC) offers a minimal version that simply analyzes the electrocardiogram (ECG) signals. As an emerging diagnostic technology of OSA, machine learning (ML) and artificial intelligence (AI) adeptly pinpoint respiratory incidents and expose delicate physiological changes, thus casting new light on the diagnostic approach to OSA. In addition, imaging examination utilizes detailed visual representations of the airway’s structure and assists in recognizing structural abnormalities that may result in obstructed airways, while sound monitoring technology records and analyzes snoring and breathing sounds to detect the condition subtly, and thus further expands our medical diagnostic toolkit. As for the future development directions, it can be predicted that interdisciplinary integrated researches, the construction of personalized diagnosis and treatment models, and the popularization of high-tech in clinical applications will become the development trends in the field of OSA evaluation and diagnosis.

Objective:To explore the perioperative safety and postoperative short-and long-term efficacy of stomach-partitioning gastrojejunostomy (SPGJ) with distal selective vagotomy (DSV) for treating benign gastric outlet obstruction (GOO).Methods:The clinical data of 26 benign GOO patients treated by Beijing Friendship Hospital, Capital Medical University from January 2019 to July 2023 were retrospectively analyzed. There were 20 males (76.9%) and 6 females (23.1%), aged from 25 to 75 years, with an average age of (55.8±13.6) years, and an average body mass index (BMI) of (20.1±3.4) kg/m 2. There were 12 cases in SPGJ-DSV group and 14 cases in SPGJ group. The main outcome was the gastrointestinal quality of life index (GIQLI) 1 year after surgery in both groups. Independent sample t-test was used to test the difference between the continuous variables with normal distribution. The comparison between groups of non-normal distribution continuous variables was tested by Mann-Whitney U test. Counting data were compared using Chi-square test or Fisher exact test. Results:There were no significant differences between the two groups in terms of operative time ( P=0.071), intraoperative blood loss ( P=0.422), time to pass gas ( P=0.538), time to liquid intake ( P=0.386), postoperative hospitalization ( P=0.431), complications within 30 days after surgery ( P=0.999), and postoperative GOOSS grade ( P=0.483). Among them, postoperative DGE occurred in one patient in each of the two groups, both of which were grade A. In the follow-up results, compared with the SPGJ group, SPGJ-DSV group had a significant advantage in GIQLI score, and the difference was statistically significant ( P=0.028). The incidence of gastric ulcer, reflux esophagitis, bile reflux and gastritis in SPGJ-DSV group was 8.3%, 8.3%, 8.3% and 58.3%, while that in SPGJ group was 35.7%, 21.4%, 21.4% and 57.1%, respectively, but there was no statistical significance between groups. Conclusion:In the treatment of benign GOO patients, SPGJ with DSV did not significantly increase the difficulty of laparoscopic procedures, operative time and intraoperative blood loss. Moreover, it showed a significant advantage in gastrointestinal quality of life 1 year after surgery. In addition, the incidence rates of gastric ulcers and reflux esophagitis were lower in the SPGJ-DSV group 1 year after surgery, but further confirmation is needed in large sample studies.

Objective To observe the efficacy and safety of Xiaoying Sanjie Granules(derived from the modified Sini San and Banxia Houpo Decoction)in the treatment of patients with benign thyroid nodules of qi stagnation and phlegm obstruction type.Methods A retrospective study was conducted.According to the treatment methods,60 patients with benign thyroid nodules of qi stagnation and phlegm obstruction type were divided into observation group and control group,30 cases in each group.The control group was given health training alone,and the observation group was given oral use of Xiaoying Sanjie Granules on the basis of treatment for the control group.The course of treatment covered 12 weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,maximum cross-section diameter of the thyroid nodule and thyroid function indexes of thyroid stimulating hormone(TSH),free triiodothyronine(FT3)and free thyroxine(FT4)in the two groups before and after treatment were observed.After treatment,the clinical efficacy and adverse reactions were compared between the two groups.Results(1)After 12 weeks of treatment,the total effective rate of the observation group was 73.33%(22/30),and that of the control group was 10.00%(3/30).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.01).(2)After treatment,the TCM syndrome scores of the observation group were significantly lower than those before treatment(P＜0.01),and the maximum cross-section diameter of the thyroid nodule was significantly smaller than that before treatment(P＜0.01).However,no obvious improvement of TCM syndromes and the maximum cross-section diameter of the thyroid nodule was presented in the control group(P＞0.05).The intergroup comparison showed that the decrease of TCM syndrome scores and the reduction of the maximum cross-section diameter of the thyroid nodule in the observation group were significantly superior to those in the control group(P＞0.05).(4)During the treatment,no obvious adverse reactions occurred in the two groups,indicating high safety.Conclusion Xiaoying Sanjie Granules exerts certain effects on patients with benign thyroid nodules of qi stagnation and phlegm obstruction type.The granuels are effective on significantly reduce the maximum cross-section diameter of the thyroid nodule,improve the clinical symptoms of patients,and has fewer adverse reactions,with high safety.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

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.

Objective:To analyze the efficacy of laparoscopic radical surgery, compared to open surgery, for incidental gallbladder cancer following cholecystectomy.Methods:Clinical data of 106 patients with incidental gallbladder cancer treated at the Second Affiliated Hospital Zhejiang University School of Medicine from April 2010 to February 2018 were retrospectively analyzed, including 66 males and 40 females, aged (64.7±7.9) years old. According to surgical approach, patients were divided into the laparoscopic group ( n=45) and open group ( n=61). Perioperative data, including intraoperative blood loss, postoperative hospital stay, and postoperative complications, were compared between the groups. Follow-ups were conducted via outpatient visits or telephone reviews. Survival analysis was performed using the Kaplan-Meier method, and the survival rates were compared using the log-rank test. Results:All 45 patients in the laparoscopic group successfully underwent the surgery without conversion to open surgery. Compared to the open group, the laparoscopic group had a reduced intraoperative blood loss [(100±25) ml vs. (200±46) ml] and a shortened postoperative hospital stay [3(2, 5) d vs. 5(4, 7) d] (both P<0.05). The postoperative complication rates were 6.7% (3/45) in the laparoscopic group and 13.1% (8/61) in the open group ( χ2=4.16, P=0.041). The cumulative survival rate after radical surgery for incidental gallbladder cancer was better in the laparoscopic group ( χ2=4.58, P=0.032). Conclusion:Compared to open surgery, laparoscopic radical surgery for incidental gallbladder cancer showed benefits in intraoperative blood loss, postoperative hospital stay, complication rates, and cumulative survival.

Risk assessment of clinical trials is of great significance to improve the quality of clinical trials. Through systematic comparative analysis of risk assessment tools for clinical trials in Britain, Germany and France, this paper found that the three countries’ risk assessment tools were consistent in terms of legal system guarantee and assessment process, but there were obvious differences in the basic risk classification and risk grading standards of clinical trials. Based on the experience of Britain, France and Germany, this paper proposed to improve the relevant regulations and documents of clinical trial risk management in China from the perspective of Chinese national conditions, further explore the factors affecting clinical trial risk, and develop and design clinical trial risk assessment tools with different discipline characteristics according to the specialties of the discipline to improve the quality and level of clinical trials.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.
