Objective:To evaluate the effect of an opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine on early postoperative recovery in patients undergoing laparoscopic radical resection of colon cancer.Methods:This study was a randomized controlled trial. From January 2023 to July 2024, 72 patients of either sex, aged 45-65 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective laparoscopic radical resection of colon cancer with general anesthesia at Yichang Central People′s Hospital, were divided into 2 groups ( n=36 each) using a random number table method: control group (group C) and opioid-sparing anesthesia strategy group (group D). Anesthesia was induced with sufentanil and propofol and maintained with propofol and remifentanil in group C. In group D, ultrasound-guided quadratus lumborum block was performed before the start of anesthesia, and anesthesia was induced with esketamine, propofol and lidocaine and maintained with esketamine, propofol, low-dose remifentanil, lidocaine and magnesium sulfate. Patient-controlled intravenous analgesia was carried out at the end of surgery until 48 h postoperatively, using dezocine for rescue analgesia. The Quality of Recovery-15 scores were assessed and recorded at 1 day before operation and 1, 3 and 7 days after operation. Ramsay sedation scores were recorded at 2, 6, 12, 24 and 48 h after surgery. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded within 24 h after surgery and during the 24-48 h postoperative period. The intraoperative consumption of opioid, emergence time, duration of postanesthesia care unit stay, time to first flatus, first ambulation time and length of postoperative hospital stay were also recorded. The postoperative complications were recorded during hospital stay and assessed with the Clavien-Dindo classification. Results:Compared with group C, the Quality of Recovery-15 scores were significantly increased at each time point after operation, Ramsay sedation scores were increased at 2, 6 and 12 h after operation, the effective pressing times of patient-controlled analgesia and rate of rescue analgesia were decreased in each postoperative period, the intraoperative consumption of remifentanil was reduced, the time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, the incidence of nausea and vomiting was decreased ( P<0.05), and no significant change was found in the emergence time or duration of postanesthesia care unit stay in group D ( P>0.05). Conclusions:The opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine can raise the quality of early postoperative recovery in the patients undergoing laparoscopic radical resection of colon cancer.

Objective:To quantitatively assess the participation of social medical insurance in palliative care medical insurance payment policies in different regions of China,explore the characteristics,find the weak points,and provide a basis for subsequent policy formulation.Methods:Based on text mining and literature review,it established a Policy Modeling Consistency(PMC)index model with 9 primary indicators and 38 secondary indicators,and quantitatively evaluated the palliative care insurance payment policies from 2017 to 2024.Results:A total of 24 policies were included,and the overall PMC index was 5.65,which was an acceptable grade,including 10 good grade policies,13 acceptable grade policies,and 1 poor grade policy.Conclusion:Overall,palliative care medical insurance payment policies are good,with relatively complete provisions in terms of coverage,medical insurance payment mechanism,supervision and management.However,there are still shortcomings in terms of financing channels,policy recipients,and incentive constraints.The follow-up should focus on broadening the financing channels,expanding the scope of recipients,and improving the incentive and constraint mechanism,so as to promote the optimization and improvement of the palliative care insurance payment system.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Objective To investigate the current situation and existing problems regarding the diagnosis and treatment integrating traditional Chinese and western medicine in the emergency departments of various general hospitals in China to provide a reference for the development of integrated traditional Chinese and western medicine emergency medicine. Methods From November 18,2022 to February 28,2023,an online questionnaire survey was conducted among 291 hospitals in 21 provinces/municipalities directly under the Central Government across the country,which was based on the members of the Emergency Medicine Professional Committee of the Chinese Association of the Integration of Traditional Chinese and Western Medicine. The questionnaire covered 5 aspects:basic information of hospitals and emergency departments,personnel allocation,medical quality management,equipment allocation,and traditional Chinese medicine techniques and skills (including the application of traditional Chinese medicine and non-drug treatment of traditional Chinese medicine). A comparative study was carried out between the "hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine" and "western medicine hospitals" on the current situation of integrated traditional Chinese and western medicine diagnosis and treatment in the emergency department. Results A total of 291 valid questionnaires were collected,covering 291 hospitals in 21 provinces and municipalities directly under the Central Government across the country. Among them,142 were hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine,and 149 were western medicine hospitals. The number of doctors in the emergency departments of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were significantly less than that of western medicine hospitals[individuals:11.00 (7.00,18.75) vs. 20.00 (13.00,31.00),P<0.01]. Specifically,the numbers of traditional Chinese medicine doctors,integrated traditional Chinese and western medicine doctors,and "western medicine doctors learning traditional Chinese medicine" in these hospitals were significantly higher than those in western medicine hospitals[individuals:4.00 (2.00,9.00) vs. 0.00 (0.00,0.00),1.00 (0.00,4.00) vs. 0.00 (0.00,0.00),2.00 (0.00,5.00) vs. 0.00 (0.00,0.00),all P<0.01],while the number of western medicine doctors was significantly less than that in western medicine hospitals[individuals:4.00 (1.00,7.50) vs. 25.50 (16.00,37.00),P<0.01]. The number of nurses in the emergency departments of hospitals of traditional Chinese medicine and integrated traditional Chinese was significantly less than that of western medicine hospitals[individuals:23.00 (16.00,38.75) vs. 42.00 (30.00,80.00),P<0.01]. The numbers of traditional Chinese medicine nurses,"western medicine nurses learning traditional Chinese medicine" in these hospitals were also significantly higher than those in western medicine hospitals[individuals:1.50 (0.00,5.75) vs. 0.00 (0.00,0.00),1.00 (0.00,7.75) vs. 0.00 (0.00,0.00),all P<0.01],while the number of western medicine nurses was significantly less than that in western medicine hospitals[individuals:15.00 (9.00,25.00) vs. 42.00 (27.00,79.00),P<0.01]. In the situation of medical quality management,the setting rates of emergency clinics,resuscitation rooms and observation rooms in western medicine hospitals were close to those in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine,but the setting rates of emergency department wards and emergency intensive care units (EICU) and the number of beds were significantly higher than those in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine[setting rate of emergency department wards:70.47％ vs. 53.52％,setting rate of EICU:67.11％ vs. 47.89％,number of beds (individuals):18.00 (0.00,30.00) vs. 2.00 (0.00,12.00) and 8.00 (0.00,12.00) vs. 0.50 (0.00,7.00),all P<0.01]. In terms of the number of visits in 2022,the annual total number of emergency visits (10000 person-times) in western medicine hospitals:6.60 (3.38,12.00) vs. 4.00 (1.25,7.00),the number of visits to the resuscitation room (10000 person-times):0.40 (0.12,1.00) vs. 0.17 (0.05,0.50) and the annual discharge volume of EICU (number of case):216.00 (0.00,550.00) vs. 0.00 (0.00,187.50) were all higher than those in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine (all P<0.01). In addition,the success rate of rescue in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine was similar to that in western medicine hospitals,and the participation rate of traditional Chinese medicine in the treatment of the resuscitation room was significantly higher than that in western medicine hospitals (P<0.01). In the situation of equipment allocation,hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine had fewer numbers of equipment than western medicine hospitals (all P<0.01). The proportion of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine equipped with non-drug treatment equipment of traditional Chinese medicine was significantly higher than that of western medicine hospitals (all P<0.01). In the application of traditional Chinese medicine techniques and skills,the proportions of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine in using Chinese patent medicines,agreed prescriptions,syndrome differentiation and treatment prescriptions,etc. were all higher than those of western medicine hospitals (application rate of Chinese patent medicines:81.69％ vs. 61.74％,application rate of agreed prescriptions:61.97％ vs. 16.78％,application rate of syndrome differentiation and treatment prescriptions:61.27％ vs. 19.46％,all P<0.01). The application rates of decoction pieces,non-decoction agreed with prescriptions,injections,hospital preparations and other dosage forms in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were all significantly higher than those in western medicine hospitals (application rate of decoction pieces:29.58％ vs. 4.70％,the application rate of non-decoction agreed prescriptions:40.85％ vs. 7.38％,application rate of injections:80.28％ vs. 53.02％,application rate of hospital preparations:33.80％ vs. 12.75％,all P<0.01). The application proportions of oral administration,nasal feeding,enema,gastric lavage,external use,intravenous injection,etc. in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were all higher than those in western medicine hospitals (oral application rate:71.13％ vs. 42.28％,nasal feeding application rate:47.18％ vs. 26.17％,enema application rate:48.59％ vs. 19.46％,gastric lavage application rate:21.13％ vs. 6.04％,external use application rate:53.52％ vs. 16.78％,intravenous injection application rate:71.83％ vs. 54.36％,all P<0.01). The application proportions of some drugs such as Shenmai/Shengmai injection,Tianma injection in hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine were higher than those in western medicine hospitals (application rate of Shenmai/Shengmai injection:59.15％ vs. 35.57％,application rate of Tianma injection:40.85％ vs. 10.07％,application rate of Danshen Honghua injection:30.99％ vs. 14.77％,application rate of Angong Niuhuang pill:26.76％ vs. 12.08％,P<0.01). The proportions of hospitals of traditional Chinese medicine and integrated traditional Chinese and western medicine in carrying out traditional Chinese medicine non-drug treatment operations such as acupuncture,acupoint application,cupping,scraping,bone-setting,moxibustion,press needles,collateral pricking method,etc. were higher than those in western medicine hospitals (application rate of acupuncture:65.49％ vs. 11.41％,application rate of acupoint application:60.56％ vs. 10.07％,application rate of cupping:32.39％ vs. 4.70％,application rate of scraping:28.17％ vs. 2.01％,application rate of bone-setting:26.76％ vs. 10.74％,application rate of moxibustion:24.65％ vs. 5.37％,application rate of press needles:17.61％ vs. 1.34％,application rate of collateral pricking method:16.90％ vs. 0.67％,all P<0.01). Conclusion The proportion of integrated traditional Chinese and western medicine personnel in the emergency departments of hospitals in China is relatively low,and the utilization rate and equipment rate of non-drug treatment of traditional Chinese medicine and traditional Chinese medicine emergency drugs are not high. It is necessary to strengthen the cultivation of integrated traditional Chinese and western medicine skills of emergency department doctors and the application of non-drug treatment of traditional Chinese medicine and traditional Chinese medicine emergency drugs to improve the ability of integrated traditional Chinese and western medicine emergency treatment.

The new-generation non-invasive prenatal screening technology (NIPT2.0) is a new method successfully realized in recent years based on high-throughput sequencing to synchronously and accurately detect fetal chromosomal aneuploidies, microdeletion/microduplication syndromes and dominantly inherited monogenic disorders. NIPT2.0 can circumvent the shortcomings of previous non-invasive prenatal screening techniques (NIPT and NIPT Plus) including incapability to detect fetal monogenic disorders, insufficient accuracy of detection and low positive predictive values for certain chromosomal abnormalities (in particular trisomy 13, sex chromosomal abnormalities, and small-segment microdeletions and microduplication syndromes). How to apply NIPT2.0 reasonably and normatively to maximize its clinical value has become an issue which requires clarification. The Reproductive Health Branch of the Chinese Maternal and Child Health Care Association has organized experts to fully discuss and jointly drafted this consensus, which has put forwards suggestions over the clinical application strategy for NIPT2.0, including the scope of application, target disease, pre-test consultation, clinical application pathway, post-test genetic counseling and intervention, quality control and limitations, for the reference by peers, with a view to standardize its application and provide better clinical service.

Objective To investigate the effects of remazolam on melatonin secretion,sleep rhythm and postoperative delirium(POD)in elderly patients undergoing spinal surgery.Methods A total of 160 elderly patients,76 males and 84 females,aged 65-80 years,BMI 18.5-24.0 kg/m2,ASA physical status Ⅱ or Ⅲ,from November 2023 to January 2024 undergoing spinal surgery(lumbar interbody fusion,posterior approach)under general anesthesia were selected.The patients were divided into two groups by random number table method:the remazolam group(group R)and the propofol group(group P),80 pa-tients in each group.Group R was given remazolam 0.3 mg/kg for anesthesia induction,and then continued to pump remazolam 0.3-0.8 mg·kg-1·h-1 for anesthesia maintenance.Group P was given propofol 2.0 mg/kg for anesthesia induction,and then continued to pump propofol 4-6 mg·kg-1·h-1 for anesthesia maintenance.The levels of melatonin and cortisol were recorded at 04:00 a.m.on the day of surgery,1 day,2 and 3 days after surgery.Pittsburgh sleep quality index(PSQI)and VAS pain scores at rest were recorded 1 day before surgery,1 day and 2 days after surgery and before discharge.The occurrence of POD and post-operative sleep disorder(POSD)were recorded.The duration of extubation,PACU stay time,total analgesia pump compressions,effective analgesia pump compressions,number of remedial analgesia cases,intraoperative hypotension,postoperative nausea and vomiting,dizziness,respiratory depression and other adverse events were recorded.Results Compared with group P,the extubation time and PACU residence time in group R were significantly shortened(P＜0.05),the level of melatonin was significantly increased while the level of cortisol was significantly decreased at 4:00 a.m.,and the PSQI was significantly decreased 1 day after surgery(P＜0.05),the incidence of POD,POSD,and intraoperative hypotension were signifi-cantly decreased(P＜0.05).There were no significant differences in extubation time,total and effective times of analgesic pump,rate of remedial analgesia,intraoperative hypotension,postoperative nausea,vom-iting,dizziness and respiratory depression between the two groups.Conclusion Remazolam has little effect on the secretion rhythm of melatonin and cortisol and the sleep rhythm after spinal surgery in elderly pa-tients,and the recovery is faster,which can reduce the incidence of POD and alleviate the sleep disorder af-ter spinal surgery.

Objective: To systematically evaluate the detection rate of prenatal depression in Chinese women, so as to provide the reference for mental health care during pregnancy among women. Methods: Publications pertaining to the detection rate of prenatal depression in Chinese women were retrieved from international and national databases from inception to July 30, 2023, including CNKI, Wanfang Data, VIP, PubMed and other databases. The Stata 17.0 software was used for meta analysis, sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using funnel plot and Egger's test. Results: A total of 5 687 publications were retrieved, and 60 studies were finally included, with 58 in Chinese and 2 in English, 51 of medium quality and 9 of high quality, and 114 168 participants. The results of meta-analysis showed that the overall detection rate of prenatal depression in Chinese women was 23.7% (95%CI: 20.0%-27.5%). The detection rates of prenatal depression in the first, second and third trimesters were 22.1% (95%CI: 15.5%-28.6%), 16.3% (95%CI: 12.0%-20.6%) and 19.9% (95%CI: 16.0%-23.7%), in Eastern and Midwestern China were 19.7% and 27.5%, and in women with an education level of junior high school or below and high school or above were 27.2% and 17.9%, respectively, with statistically significant differences (all P<0.05). Sensitivity analysis showed that the study results were stable. There were publication bias in the results of overall detection rate of prenatal depression, and detection rates in the second and third trimester. Conclusions The overall detection rate of prenatal depression in Chinese women ranges from 20.0% to 27.5%. There are differences in the detection rate of prenatal depression in different pregnancies, with the highest detection rate in the first trimester.
