OBJECTIVE: To observe the efficacy and safety of Tiaowei Jiannao acupuncture (acupuncture for regulating defensive qi and nourishing brain) for post-ischemic stroke insomnia (PISI). METHODS: A total of 96 patients with PISI were randomized into an acupuncture group (32 cases, 1 case was excluded), a medication group (32 cases, 1 case dropped out, 1 case was excluded) and a sham-acupuncture group (32 cases, 1 case dropped out, 1 case was excluded). In the acupuncture group, Tiaowei Jiannao acupuncture was applied at bilateral Shenmai (BL62), Zhaohai (KI6), Hegu (LI4), Taichong (LR3), and Baihui (GV20), Sishencong (EX-HN1), Yintang (GV24⁺), Shenting (GV24), once a day, 1-day interval was taken after 6-day treatment, for 3 weeks totally. In the medication group, eszopiclone tablet was given orally, 1-3 mg a time, once a day for 3 weeks. In the sham-acupuncture group, non-invasive sham acupuncture was applied, the acupoint selection, frequency and course of treatment were the same as the acupuncture group. Before treatment, after 2,3 weeks of treatment, the scores of Pittsburgh sleep quality index (PSQI), self-rating sleep scale (SRSS), National Institutes of Health Stroke scale (NIHSS), Hamilton depression scale-17 (HAMD-17) were observed; before and after treatment, the sleep parameters were recorded using polysomnography (PSG); and the efficacy and safety were evaluated after treatment in the 3 groups. RESULTS: After 2,3 weeks of treatment, the scores of PSQI, HAMD-17 and SRSS in the acupuncture group and the medication group, as well as the SRSS scores in the sham-acupuncture group were decreased compared with those before treatment (P<0.05); after 2 weeks of treatment, the NIHSS score in the acupuncture group was decreased compared with that before treatment (P<0.05); after 3 weeks of treatment, the NIHSS scores in the acupuncture group, the medication group and the sham-acupuncture group were decreased compared with those before treatment (P<0.05). After 3 weeks of treatment, the scores of PSQI, SRSS, HAMD-17 and NIHSS in the acupuncture group and the medication group, as well as the NIHSS score in the sham-acupuncture group were decreased compared with those after 2 weeks of treatment (P<0.05). After 2,3 weeks of treatment, the scores of PSQI, SRSS and HAMD-17 in the acupuncture group and the medication group were lower than those in the sham-acupuncture group (P<0.05), the NIHSS scores in the acupuncture group were lower than those in the medication group and the sham-acupuncture group (P<0.05); after 3 weeks of treatment, HAMD-17 score in the acupuncture group was lower than that in the medication group (P<0.05), the NIHSS score in the medication group was lower than that in the sham-acupuncture group (P<0.05). Compared before treatment, after treatment, the total sleep time was prolonged (P<0.05), the wake after sleep onset, sleep latency, and non-rapid eye movement (NREM) sleep latency were shortened (P<0.05), the sleep efficiency was improved (P<0.05), the number of awakenings was reduced (P<0.05), the percentage of rapid eye movement (REM%) and the percentage of NREM stage 1 (N1%) were decreased (P<0.05), the percentage of NREM stage 2 (N2%) and the percentage of NREM stage 3 (N3%) were increased (P<0.05) in the acupuncture group and the medication group; the sleep latency was shortened in the sham-acupuncture group (P<0.05). After treatment, the PSG indexes in the acupuncture group and the medication group were superior to those in the sham-acupuncture group (P<0.05); in the acupuncture group, the number of awakenings was less than that in the medication group (P<0.05), the REM% and N1% were lower than those in the medication group (P<0.05), the N2% and N3% were higher than those in the medication group (P<0.05). The total effective rate were 93.5% (29/31) and 90.0% (27/30) in the acupuncture group and the medication group respectively, which were higher than 10.0% (3/30) in the sham-acupuncture group (P<0.05). There was no serious adverse events in any of the 3 groups. CONCLUSION Tiaowei Jiannao acupuncture improves the insomnia symptoms in patients with ischemic stroke, improves the quality of sleep, increases the deep sleep, promotes the recovery of neurological function, and relieves the depression. It is effective and safe for the treatment of PISI.

Objective To compare the contents of alkaloid in Aconiti Kusnezoffii Radix with different degrees of processing and their effects on electrocardiogram and vagus nerve action potential in SD rats;To establish a toxicity evaluation method for Aconiti Kusnezoffii Radix and its processed products.Methods HPLC was used to determine the contents of six alkaloid components,including benzoyl neoaconitine,benzoyl aconitine,benzoyl subeaconitine,neoaconitine,subeaconitine and aconitine in Aconiti Kusnezoffii Radix and Aconiti Kusnezoffii Radix Cocta of soaking and boiled for 30 minutes,boiled for 4 h without soaking,soaking and boiled for 4 h,and soaking and boiled for 8 h.SD rats were subjected to sublingual drainage with Aconiti Kusnezoffii Radix and four types of processed products.The vagus nerve action potential and electrocardiogram of rats before and after administration were recorded,and the correlation analysis between alkaloid content and vagus nerve action potential and heart rate was conducted.Results The contents of alkaloid of the four processed products showed that the content of diester alkaloids was soaking and boiled for 30 min>boiled for 4 h without soaking>soaking and boiled for 4 h>soaking and boiled for 8 h;monoester alkaloid content:boiled for 4 h without soaking>soaking and boiled for 30 min>soaking and boiled for 4 h>soaking and boiled for 8 h.After the administration of each sample,compared with the basal discharge,the vagus nerve discharge of rats with different processed products was changed by sublingual administration,heart rate increased,the degree of arrhythmia increased,and it varied with the degree of processing;the results of correlation analysis showed that there was a significant correlation between the nerve discharge area and the contents of diester alkaloids and total alkaloids.Conclusion The action potential of the vagus nerve and electrocardiogram of rats after sublingual drainage administration can reflect the degree of numbness in the tongue,which can provide reference for the study of tongue sensation of Aconiti Kusnezoffii Radix.

Objective:This study investigates the influence of the apolipoprotein E ε4(APOE ε4)genotype on the relationship between glucose-lipid metabolism disorders and diabetes-related cognitive impairment(DCI).Methods:A case-control study was conducted involving 891 patients with type 2 diabetes mellitus(T2DM)with a mean age of(62.1±13.8)years, all of whom underwent elective surgery at the First Hospital of Shanxi Medical University between January 2017 and December 2022.Among these participants, 229 were diagnosed with DCI(case group), while 662 were cognitively normal(control group).Routine clinical information was collected, and peripheral venous blood samples were analyzed for glycated hemoglobin(HbA1c)and blood lipid levels.The single nucleotide polymorphisms rs429358 and rs7412 were analyzed to determine the presence of the APOE ε4 genotype.Stepwise Logistic regression was employed to identify independent risk factors for DCI, and subgroup analyses were performed to evaluate the effect of the APOE ε4 genotype on the relationship between HbA1c and blood lipid levels in relation to DCI risk. Results:Among all patients, female gender( OR=1.915, 95% CI: 1.393-2.631, P<0.001), longer duration of T2DM( OR=1.169, 95% CI: 1.087-1.257, P<0.001), elevated triglycerides( OR=1.161, 95% CI: 1.041-1.294, P=0.007), and being an APOE ε4 carrier( OR=1.638, 95% CI: 1.115-2.405, P=0.012)were identified as independent risk factors for developing DCI.High levels of low-density lipoprotein(LDL)were found to be independently associated with an increased risk of DCI specifically in APOE ε4 carriers( OR=1.408, 95% CI: 1.060-1.870, P=0.018), but not in non-APOE ε4 carriers( P>0.05).In contrast, elevated HbA1c was independently associated with a higher risk of DCI in non-APOE ε4 carriers( OR=1.220, 95% CI: 1.040-1.430, P=0.014), but not in APOE ε4 carriers( P>0.05).Additionally, elevated triglycerides were independently linked to an increased risk of DCI across the entire sample and within each APOE ε4 genotype subgroup. Conclusions:The APOE genotype plays a significant role in modulating the relationship between dyslipidemia and the risk of developing DCI.This highlights the critical importance of lipid metabolism disorders and APOE risk genes in both the development and progression of DCI.These findings offer valuable insights for future clinical and mechanistic studies focused on DCI.

Objective:To evaluate the clinical effect of the position pillows for neuraxial anesthesia.Methods:This was a prospective randomized controlled trial. Four hundred and twelve patients regardless of gender, aged ≥18 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, who underwent elective surgery under neuraxial anesthesia at Peking University Third Hospital from February to October 2023, were selected and divided into 2 groups ( n=206 each) using a random number table method: pillow group (P group) and control group (C group). Group C underwent the conventional procedure for neuraxial anesthesia. The patients were placed in a position using the position pillow on the basis of oral education before routine anesthesia in group P. The success rate of puncture at first attempt, puncture time and position placement time were recorded. The adjustment of position, body movement and occurrence of discomfort during the puncture were also recorded. The visual analogue scale score was used to evaluate the level of anxiety before positioning, after positioning and after anesthesia. The visual analogue scale score was used to evaluate the patient′s comfort and the operator′s satisfaction with position after the anesthesia was completed. Results:Compared with group C, the time for positioning was significantly shortened, the anxiety level was decreased after positioning and after anesthesia, the rate of improvement in anxiety was increased, the scores for the patient′s comfort and the operator′s satisfaction with position were increased ( P<0.05), and no significant changes were found in the success rate of puncture at first attempt, puncture time and incidence of body movement during the puncture and incidence of the adjustment of position ( P>0.05). No discomfort was observed in either group during the puncture. Conclusions:This new type of position pillows for the neuraxial anesthesia can not only optimize the effect of position placement, but also improve the patients′ comfort.

Objective To analyze the effect of air pollution on daily outpatient visits for diabetes, and to provide reference for the management of outpatients with diabetes. Methods Data on outpatient visits for diabetes in a hospital between July 1, 2018 to July 31, 2022 were collected. The correlation between air quality and daily outpatient visits due to diabetes was analyzed using distributed lag non-linear model (DLNM). Results The results showed that the increase in the concentrations of PM_2.5 and PM₁₀ in the air was related to the increase in the daily outpatient visits for diabetes, with a lagging effect. The accumulative effect in high PM_2.5 concentration was statistically significant for both males and females, and the number of outpatients reached the maximum value at lag5 for males and at lag6 for females. The accumulative effect was not statistically significant either at low or high concentrations of PM_2.5 in the young and middle-aged population. However，it was statistically significant in the elderly population, especially when exposed to high concentration of PM_2.5, the daily outpatient visits increased significantly. Conclusion PM_2.5, PM₁₀ and other harmful pollutants in the air have an impact on the daily diabetic outpatients and increase their visits.

Objective: To optimize the pretreatment method of N-nitrosamine compounds in ready-to-eat aquatic products. Methods: Market-sold ready-to-eat aquatic products were collected, homogenized and distilled by steam. The samples were extracted for 10 minutes using dispersive liquid-liquid microextraction (DLLME) with ethanol, trichloromethane and sodium chloride (3.0 g). After centrifugation, the organic phase in the lower layer was collected and subjected to gas chromatography-tandem mass spectrometry (GC-MS/MS). The six common N-nitrosamine compounds were determined in ready-to-eat aquatic products using multiple reaction monitoring mode (MRM) and quantified by the internal standard method. Results: The optimized method exhibited a good linear relationship at concentrations of 10.0 to 500 μg/L for determination of 6 N-nitrosamine compounds (correlation coefficient of greater than 0.999), with 0.05 to 0.60 μg/kg limit of detection, 0.15 to 1.60 μg/kg limit of quantitation, mean spiked recovery rates of 71.8% to 108.9%, and relative standard deviations of 1.4% to 8.6%. N-Nitrosodimethylamine showed the highest detection rate in 20 market-sold ready-to-eat aquatic products (90%), and the detection rates of N-Nitrosopyrrolidine, N-Nitrosodiethylamine and N-dibutylnitrosamine were 15%, 10% and 10%, respectively. Conclusion Steam distillation combined with DLLME may optimize the pretreatment method of N-nitrosamine compounds in ready-to-eat aquatic products and meet the measurement requirements.

Objective:To investigate the clinical application of multimodal low-opioid combined with saphenous nerve block analgesia in elderly patients undergoing knee arthroplasty.Methods:This study is a randomized controlled study.A total of 60 elderly patients who underwent elective knee arthroplasty in the Department of Orthopedics, the First Hospital of Shanxi Medical University from January 2021 to December 2021 were selected and divided into 2 groups by numerical randomization: mode low opioid analgesia regimen group(observation group)and traditional analgesia regimen group(control group), 30 cases in each group.Observation group: (1)Preemptive analgesia: Oral celecoxib 200 mg, qd.from 3 days before surgery, the mini-mental state examination(MMSE)score was used to evaluate the cognitive function; (2)Intraoperative analgesia: After the prosthesis was installed, choose to inject analgesics around the knee joint(ropivacaine 200 mg, morphine 5 mg, epinephrine 0.25 mg, dexamethasone 5 mg/100 ml normal saline, also known as "cocktail" solution); (3)Postoperative analgesia: After the operation, continuous saphenous nerve block(0.2% ropivacaine, 2 ml/h)was performed under ultrasound guidance, and the dose of nerve block was adjusted according to the degree of rehabilitation training.Control group: no special treatment before and during the operation, traditional postoperative patient-controlled intravenous analgesia(PCIA)was used after the operation, the formula WAs as follows: sufentanil(2 μg/kg)+ flurbiprofen axetil(200-300 mg)+ Tropisetron(5-10 mg). The numerical rating scale(NRS)scores were observed and recorded 1 day before surgery, 6, 12, 24, and 48 hours after surgery; the time of the first active straight leg raising after surgery, the time of landing; the range of motion(ROM)of the knee joint 3, 7, and 14 days after surgery; the American Hospital for Special Surgery Knee Score(HSS)at 14 days, 1, 3, and 6 months after surgery; serum substance P(SP)and interleukin-6(IL-6)concentrations 1 day before surgery and 48 hours after surgery, and adverse events were recorded.Results:Compared with the control group, the patients in the observation group had lower NRS scores at 6, 12, 24, and 48 hours after the operation( t=27.705, 27.532, 21.739, 25.780, all P<0.05); the first active straight leg raising time and the time of landing earlier after the operation, and the knee joint at 3, 7, and 14 days after the operation, the range of motion(ROM)was better( t=35.496, 43.716, 3.766, 5.216, 6.009, all P<0.05). And the American hospital for special surgery knee score(HSS)was higher at 14 days, 1 month, and 3 months after surgery( t=19.247, 32.337, 22.651, all P<0.05), but there was no significant difference at 6 months after surgery.Simultaneously, the serum SP and IL-6 concentrations in the observation group 48 h after the operation were (431.0±11.3)ng/L and(11.9±2.7)ng/L, respectively.Compared with the control group(442.5±15.6)ng/L, (14.4±2.9)ng/L( t=5.362, 4.144, both P<0.05). Compared with the control group, which were lower than those in the incidence of postoperative nausea and vomiting was lower, the length of hospital stay was shorter in the observation group( χ2=4.630, t=3.311, P=0.031, 0.002), and the other indicators had no statistical differences(all P>0.05). Conclusions:Multimodal low-opioid combined with saphenous nerve block analgesia can significantly reduce perioperative pain in elderly patients undergoing knee arthroplasty, improve early postoperative mobility, and speed up postoperative functional recovery.

Objective:To evaluate the significance of copy number variation (CNV) and metagenomic next-generation sequencing (mNGS) of cerebrospinal fluid (CSF) in the diagnosis of meningeal carcinomatosis (MC).Methods:Ten patients with MC diagnosed in the Department of Neurology of Peking Union Medical College Hospital from March 2022 to June 2022 were consecutively enrolled in this study. The patients were diagnosed according to the criteria of the Chinese expert consensus on the diagnosis of MC by the Chinese Society of Infectious Diseases and Cerebrospinal Fluid Cytology, and the diagnosis of MC was confirmed by CSF cytology. The control group included 10 patients who were diagnosed as autoimmune encephalitis or viral encephalitis. CSF mNGS and CNV analysis were performed simultaneously in all the patients.Results:Of the 10 patients with MC, 6 had lung adenocarcinoma, 4 had breast cancer. CSF mNGS and CNV analysis detected large CNV in 8 of 10 patients with MC, including 4 patients with breast cancer and 4 patients with lung cancer. The results of pathogenic microorganism analysis of CSF mNGS in all the patients were negative. Meanwhile, large CNV was not detected in the control group.Conclusions:CSF CNV can serve as a diagnostic marker for MC. The combination of mNGS and CNV analysis has demonstrated a high positive rate in the diagnosis of MC. The dual-omics analysis of pathogenic microorganisms and CNV has been proposed as a potential strategy to further expand the clinical utility of CSF mNGS in the realm of auxiliary diagnosis.
