Objective : To explore the differences in oxidative stress levels between patients with and without non-suicidal self-injury(NSSI) behavior in depressive disorders, and their correlation with depressive symptoms, disease duration, and self-injury frequency. Methods : A total of 95 subjects were included in the study, including 65 patients with depression(patient group). They were divided into NSSI subgroup(31 cases) and Non-NSSI subgroup(34 cases) based on whether they had NSSI. 30 healthy control group cases(HC). Enzyme linked immunosorbent assay(ELISA) was used to detect the levels of superoxide dismutase(SOD), catalase(CAT), malondialdehyde(MDA), glutathione peroxidase(GPX), and oxidized low-density lipoprotein(OxLDL) in the peripheral blood of the subjects. The Hamilton depression rating scale(HAMD-17) was used to assess the patient′s condition, and the Ottawa self-injury inventory(OSI) was used to quantitatively evaluate the self-injury frequency of NSSI group patients. Results : The levels of SOD, CAT,MDA,GPX and OxLDL in the patient group were significantly higher than those in the control group(P<0.05). The levels of SOD, CAT, MDA,GPX and OxLDL in the NSSI subgroup were significantly higher than those in the Non-NSSI subgroup and the control group(P<0.05).The duration of the NSSI subgroup was positively correlated with the levels of SOD,CAT,and MDA(r=0.504,P=0.004; r=0.568,P=0.001; r=0.404,P=0.024),and the HAMD-17 score was positively correlated with the levels of SOD,CAT,and MDA(r=0.573,P=0.001; r=0.577,P=0.001; r=0.477,P=0.007). The frequency of self-injury was positively correlated with the levels of SOD and MDA(r=0.558,P=0.001; r=0.494,P=0.005). Conclusion The OS level of patients with depression is significantly higher than that of the healthy population,and among them,patients with depression accompanied by NSSI have a more significant increase in oxidative stress level. Elevated levels of OS may affect the severity,duration,and frequency of self-injurious behavior in patients with depression accompanied by NSSI.

OBJECTIVE To screen potential adverse drug event （ADE） signals for the treatment of multiple sclerosis （MS） with ofatumumab， and to provide reference for the safe use of drugs in clinical practice. METHODS Using “ofatumumab” and the trade name “Kesimpta” as the search keywords， adverse event （AE） reports related to ofatumumab included in FDA Adverse Event Reporting System database from January 2009 to December 2023 were screened， and their reason contained the “multiple sclerosis”； ADE signal mining and analysis were conducted by reporting odds ratio method and proportional reporting ratio method. RESULTS A total of 21 759 eligible AE reports were selected， involving 62 449 AE cases； 27 system organ classes included general diseases and various reactions at the site of administration （15 021 cases）， neurological diseases （9 668 cases）， infectious and invasive diseases （5 967 cases）， injury， poisoning and surgical complications （4 952 cases）， musculoskeletal and connective tissue disorders （4 647 cases）. A total of 21 759 AE reports correspond to 606 ADE signals， including 234 ADE positive signals. A total of 107 ADE positive signals were not included in drug instruction of ofatumumab， including flu-like diseases， nasopharyngitis， cough， urinary tract infection， sore throat， insomnia， runny nose， anemia， hair loss， atrial fibrillation， and thrombocytopenia， etc. CONCLUSIONS In the process of using ofatumumab for MS， sufficient attention should be paid to ADE included in drug instructions. The ADE with strong signal strength screened in this study should also be paid special attention to， such as flu-like diseases， hemocytopenia， temperature intolerance， optic neuritis， and moyamoya disease. The increased risk of infection， cardiovascular disease， and potential damage to the respiratory and spiritual systems caused by ofatumumab can not be ignored.

ObjectiveTo evaluate the dynamic disinfection effect of the upper-room 222 nm ultraviolet radiation on the air in different areas of the emergency department, and to provide references for a new solution of air disinfection that man-machine coexisted in the medical and healthcare institutions. MethodsThe upper-room 222 nm ultraviolet radiation air sterilizers were installed at a height of 2.3‒2.6 m from the ground in the observation room, computed tomography (CT) scanning room, rescue room and consulting room of the emergency department in Beijing Tiantan Hospital, Capital Medical University . The test area was divided into a 222 nm ultraviolet group and a control group according to whether the 222 nm ultraviolet germicidal air disinfection was conducted or not. The experimental group started air disinfection at8:00 a.m., and the air sampling was conducted from 9:00 a.m. to 16:00 p.m., with a 10 min sampling interval of every 1 hour. While the control group only collected air sample with the same air sampling method used in the experimental group, without air disinfection. The air microbial sampler with six-level sieve impingement was used for the air sampling, and the differences in the total number of airborne bacterial colonies were compared between the two groups. ResultsA total of 128 air samples were collected in the trial, of which 64 were from the experimental group and 64 from the control group. The total number of airborne bacterial colonies in the experimental group was lower than that in the control group (all P<0.001), and was maintained at a lower level throughout the entire period. The killing rate of 222 nm ultraviolet radiation to airborne microorganisms was approximately 55.76% to 76.33% in different sampling areas. The qualified rates of the total number of dynamic airborne bacterial colonies in the observation room, rescue room and consulting room were improved from 12.50%, 37.50% and 25.00% to 81.25%, 100.00% and 100.00%, respectively (all P<0.001). Over 62.50% of the time, the air quality in the consulting room and CT room in the 222 nm ultraviolet group met the environment standards for airborne bacterial colony criteria of class Ⅰ or class Ⅱ. ConclusionThe upper-room222 nm ultraviolet radiation germicidal disinfection can effectively reduce the total number of airborne bacterial colonies and improve the environment for emergency department, and the continuous using of it is helpful for keeping the air safe and clean.

ObjectiveUsing the Delphi method and analytic hierarchy process （AHP） to screen diagnostic items for qi stagnation syndrome and determine their weights， providing a reference for the development of a diagnostic scale of qi stagnation syndrome. MethodsLiterature related to qi stagnation syndrome were screened from databases including CNKI， Wanfang， VIP， SinoMed （from inception to October 31， 2020）. Through systematic review of literature and expert discussions， the information on the four examinations of traditional Chinese medicine were organized and an item pool was constructed. The Delphi method was used to screen the item indicators， while the AHP was employed to determine their weights. Statistical methods such as mean value， full score ratio， rank sum， unimportant percentage， and coefficient of variation were used for item screening， with the weights calculated by AHP serving as the item weights. ResultsA total of 235 articles and books were included for analysis， resulting in an item pool of 16 items. After three rounds of expert consultation， a total of 84 valid questionnaires were collected， with a total expert enthusiasm coefficient of 99% and authority coefficient of 0.86， 0.84， 0.83， respectively， and the coordination coefficients were 0.45， 0.49， and 0.29， respectively. Through the statistics analysis， 8 diagnosis items were screened out， including distension （stuffi-ness） or distending pain or scurrying pain， wiry pulse， depressed emotions， frequent sighing， deep and wiry pulse， irritability， pale red tongue， and thin white coating. The AHP showed that the order of weights of the first-level indicators from high to low was clinical symptoms， pulse manifestation， and tongue manifestation； the order of weights of the second-level indicators from high to low was distension （stuffiness） or distending pain or scurrying pain， wiry pulse， depressed emotions， frequent sighing， deep and wiry pulse， irritability， pale red tongue， and thin white coating. ConclusionBy applying the Delphi method and AHP to analyze and evaluate the diagnostic items for qi stagnation syndrome， key diagnostic items were screened and their weights determined， laying the foundation for the development of a diagnostic scale for qi stagnation syndrome.

Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.

Objective:To combine and improve two kinds of classical transvaginal cervical cerclage,and to provide a new reference for the clinical treatment of patients with cervical insufficiency(CIC).Methods:Retro-spective analysis was performed on the clinical data of 117 patients who underwent transvaginal cervical cerclage due to CIC from January 1,2018 to August 31,2023 in the Second Affiliated Hospital of Kunming Medical Univer-sity.According to different surgical methods,the patients were divided into the modified cerclage group(40 ca-ses),the McDonald cerclage group(40 cases)and the Shirodkar cerclage group(37 cases).Intraoperative and postoperative conditions and pregnancy outcomes were compared.Univariate and multivariate Logistic regression analysis was performed to analyze the related factors of preterm birth after modified cervical cerclage and the oth-er two groups of classical cervical cerclage.Results:①Compared with the McDonald cerclage group,the modified cerclage group had longer effective cervical length,longer delivery and gestational weeks,higher term delivery rate,and shorter post-operative contraction inhibitor time,with statistical significance(P＜0.05).Compared with the Shirodkar cerclage group,the operation time of patients in the modified cerclage was significantly shortened,the amount of intraoperative blood loss was reduced,the use time of postoperative contraction inhibitors was shortened,and the rate of postoperative wire-cutting was decreased,with statistical significance(P＜0.05).②Multivariate Logistic regression analysis of preterm birth showed that the longer the length of the cervix and the later gestational age when the modified cervical cerclage was performed with reference to McDonald's cerclage,the longer the length of the cervix after surgery,the later the gestational age when the suture was removed.The risk of preterm birth was reduced(OR＜1,P＜0.05),while preoperative BMI≥24 kg/m2 was associated with an increased risk of preterm birth(OR＞1,P＜0.05).Using Shirodkar's cerclage as reference,the risk of preterm delivery was consistent between the two types of cervix(P＞0.05).Longer cervical length and later gestational age after suture removal reduced the risk of preterm delivery(OR＜1,P＜0.05).Conclusions:The modified transvaginal cervical cerclage is simple and safe in clinical application,it has certain advantages in improving ad-verse pregnancy outcomes of pregnant women,which provides a new reference for the treatment of pregnant women with CIC.Due to the small number of cases included in the study,comprehensive evaluation by clinicians is still needed for clinical application.
