ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

BackgroundCurrently， the problem of depressed mood in college students is becoming more prominent. The experience of childhood maltreatment is a significant contributor to depression among college students. Although the association between the two has been confirmed， the specific psychosocial mechanisms underlying how childhood maltreatment affects college students' mental health remain insufficiently evidenced. ObjectiveTo explore the mediating role of emotion regulation difficulties in the relationship between childhood maltreatment and depression among college students， and to investigate the moderated effects of psychological resilience and family socioeconomic status， aiming to provide references for improving depressive symptoms in college students. MethodsOn 14 March 2024， a cluster sampling method was employed to recruit 751 college students from a university in Heilongjiang Province. Participants were assessed with Childhood Trauma Questionnaire （CTQ）， Difficulties in Emotion Regulation Scale （DERS）， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， 10-item Connor-Davidson Resilience Scale （CD-RISC-10） and Family Socioeconomic Status Questionnaire. Pearson correlation analysis was adopted to examine the correlation between the scores of scales. Model 4 and model 7 in Process 4.2 were used to test the mediating effects of emotional regulation difficulties and the moderated effects of psychological resilience and family socioeconomic status. Results① A total of 712 （94.81%） valid questionnaires were collected. ② College students' CTQ score was positively correlated with DERS score and PHQ-9 score （r=0.296， 0.507， P<0.01）， and negatively correlated with CD-RISC-10 score and Family Socioeconomic Status Questionnaire score （r=-0.148， -0.229， P<0.01）. ③ The indirect effect value of difficulties in emotion regulation on the relationship between childhood maltreatment and depression was 0.091 （95% CI： 0.018~0.046）， accounting for 17.95% of the total effect. ④ The first half of the mediation model "childhood maltreatment → difficulties in emotion regulation → depression" （childhood maltreatment → difficulties in emotion regulation） was moderated by psychological resilience （β=-0.030， t=-6.147， 95% CI： -0.040~-0.020） and family socioeconomic status （β=-0.051， t=-3.929， 95% CI： -0.077~-0.026）. ConclusionChildhood maltreatment exerts both a direct effect on college students' depression and an indirect effect through emotion regulation difficulties. The childhood maltreatment → emotion regulation difficulties pathway in this mediation model is moderated by psychological resilience and family socioeconomic status. ［Funded by Qiqihar Medical University Graduate Student Innovation Fund Project （number， QYYCX2023-48）； Special Research Fund Project for Young Doctors of Qiqihar Academy of Medical Sciences （number， QMSI2021B-08）］

Acute cerebral infarction(ACI)has the characteristics of onset nasty and high mortality,and thus the rapid determination of the occurrence and development of ACI plays a key role in the diagnosis,treatment and prognosis of ACI patients.It has shown that the serum level of human haptoglobin(Hp)is related to ACI.In this study,surface enhanced Raman scattering(SERS)combined with immune recognition was applied to establish a quantitative analysis method for serum Hp.Firstly,the SERS substrate of silver nanoparticles was prepared on silicon wafer,and 4-mercaptobenzoic Acid(MBA)was used as a Raman probe by forming Ag—S bond and connecting it on the surface of nanoparticles.The carboxyl group of MBA was linked to amino group of self-made high-affinity antibody through forming CO—NH structure thus forming a SERS self-assembled chip of Hp(Ag/MBA/anti-Hp).Hp in serum could be specifically captured by antibodies on SERS substrate,which caused the shift of SERS characteristic peak of MBA.The results showed that there was a good linear relationship between the logarithm of Hp concentration and the SERS characteristic peak shift of MBA.The detection range was 1-1000 ng/mL(R2=0.988).The Hp concentrations in serum of 90 ACI patients were determined by this method,and the results were consistent with those of ELISA method,which proved the practicability and accuracy of this method.This method was highly specific,simple and convenient,which could realize the specific recognition and quantitative analysis of serum Hp,so as to be an effective means for clinical detection of serum Hp,thus providing a reference for the treatment and prognosis of ACI.

Clinical trials of drugs for rare diseases face special challenges such as a limited number of patients,difficult recruitment,long trial period,and frequent video interviews during the trial.Therefore,in the clinical operation of rare diseases,a decentralized clinical trials(DCT)model based on the"patient-cen-tred"research and development concept is implemented.With the help of decentralized elements and digital health technology,the barriers of geographical restrictions can be overcome and subjects do not have to be limit-ed to traditional clinical trial sites(hospitals/research centers),which can significantly reduce the burden on subjects,increase their representation,and obtain a wider range of scientific research data.To guide the indus-try's scientific and standardized application of DCT in the research and development of drugs for rare diseases,the Center for Drug Evaluation of the National Medical Products Administration(NMPA)organized the stake holders to draft the Technical Guideline for the Application of Decentralized Clinical Trials in the Research and Development of Drugs for Rare Diseases.This guideline provides scientific recommendations for the development and implementation of DCT for rare disease drugs.It aims to solve the difficult and key problems during rare disease drug research and development,improve the efficiency and optimize patient experience.This article,combining the research and development concepts in the guideline,explains the current research and develop-ment thinking on the application of DCT in the research and development of rare disease drugs,with a view of providing reference for the industry.

Objective:To construct a nomogram model for predicting frailty in elderly hypertensive patients, and to evaluate the discrimination and consistency of the model.Methods:A total of 317 patients with essential hypertension who were admitted to Hebei Eighth People′s Hospital from February 2021 to June 2022 were taken, they were divided into modeling group (190 cases) and verification group (127 cases) according to the proportion of 6∶4, the patients in the modeling group were divided into the asthenic group (45 cases) and the non asthenic group (145 cases) according to whether the patients in the modeling group had asthenia. The nomograph model was constructed based on the results of Logistic analysis.Results:The age, obesity or overweight ratio, diabetes ratio and systolic blood pressure in the frail group were significantly higher than those in the non-frail group: (76.25 ± 3.64)years vs.(70.44 ± 3.82) years, 51.11%(23/45) vs. 24.83%(36/145), 46.67%(21/45) vs. 17.24%(25/145), (156.46 ± 18.64) mmHg (1 mmHg = 0.133 kPa) vs. (143.25 ± 12.38) mmHg, and the mini-nutrition assessment summary form (MNA-SF) score was significantly lower than that in the non-frail group: (11.45 ± 2.06) scores vs. (13.12 ± 1.22) scores, there were statistical differences ( P<0.05). Logistic results showed that age, body mass index, diabetes, and systolic blood pressure were the risk factors for frailty ( P<0.05). The receiver operating characteristic (ROC) curve evaluation showed that the area under the curve (AUC) in the modeling group was 0.998, and AUC in the validation group was 0.954. The Hosmer-Lemeshow goodness of fit test showed: modeling group χ2 = 6.18, P = 0.627; validation group χ2 = 6.58, P = 0.582. Conclusions:The nomogram prediction model of frailty risk in elderly hypertensive patients has good consistency and differentiation

Objective To investigate the effect of varying ureteral wall thickness(UWT)at the site of ureteral stones on the clinical efficacy of ureteroscopic lithotripsy(URL).Methods The clinical data of 164 patients with ureteral stones in our hospital were retrospectively analyzed.According to different UWT,the patients were divided into the mild thickening group(84 cases,UWT<3.16 mm),the moderate thickening group(31 cases,UWT 3.16 to 3.49 mm),and the severe thickening group(49 cases,UWT>3.49 mm),and the differences of clinical related indicators among the three groups were compared.Results The incidence of postoperative renal colic and leukocyte disorder in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,and the differences were statistically significant(P<0.05).The postoperative catheterization time in the mild thickening group and the moderate thickening group were shorter than that in the severe thickening group,and the incidences of secondary lithotripsy,residual stones and stone return to kidney in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,with statistically significant differences(P<0.05).The length of hospital stay and hospitalization cost in the mild thickening group and the moderate thickening group were shorter/less than those in the severe thickening group,with statistically significant differences(P<0.05).Conclusion With the increase of UWT(especially when UWT>3.49 mm),the incidence of postoperative complications and hospitalization cost of URL increase to varying degrees,and the surgical efficacy decreases.In clinical work,UWT measurement holds potential value in predicting the surgical efficacy and complications of URL.

AIM To study the protective effects and mechanism of pueraria isoflavones on myocardial injury in ovariectomized rats.METHODS Thirty-six rats were randomly divided into the sham operation group,the model group,the estradiol valerate group(0.1 mg/kg)and the low,medium and high dose pueraria isoflavones groups(55,110,220 mg/kg).In contrast to the rats of the sham operation group having their small pieces of adipose tissue removal around the ovaries,rats of the other groups had their bilateral ovaries excised,followed by the 16-week corresponding oral drug administration 2 weeks later at a once daily frequency for,6 days a week.At the end of the 16th week,the rats had their hemodynamics[systolic pressure(SBP),diastolic pressure(DBP),mean pressure(MBP),left ventricular systolic pressure(LVSP),left ventricular diastolic pressure(LVMP),and the maximum rate of increase and decrease of left ventricular pressure during isovolumic contraction(±dp/dtmax)]detected by PowerLab;their cardiac pathological changes observed by HE staining;their levels of creatine kinase(CK),lactate dehydrogenase(LDH),total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)and glucose(Glu)in plasma detected by biochemical analyzer;their myocardial level of adenosine triphosphate(ATP)detected by colorimetry;their mRNA expressions of glucose transporter 4(GLUT4),lactate dehydrogenase A(LDHA),carnitine palmitoyl transferase-1(CPT-1α),acyl coenzyme A carboxylase(ACC),liver kinase B1(LKB1),adenylate-activated protein kinase(AMPK)and peroxisome proliferator-activated receptor γ coactivator factor 1α(PGC-1α)detected by RT-qPCR;and their myocardial expressions of energy metabolism related proteins LKB1,p-AMPK/AMPK and PGC-1α detected by Western blot.RESULTS Compared with the model group,the pueraria isoflavones groups displayed decreased levels of SBP,DBP,MBP,LVSP,LVMP(P＜0.05,P＜0.01);increased-dp/dtmax(P＜0.05,P＜0.01);improved myocardial fibrinolysis,gap widening and inflammatory infiltration caused by ovariectomy;decreased activities of LDH and CK(P＜0.05);increased myocardial ATP level(P＜0.05,P＜0.01);decreased levels of TC,TG,LDL-C and Glu(P＜0.05,P＜0.01);increased HDL-C level(P＜0.05,P＜0.01);increased myocardial mRNA expressions of GLUT4,LDHA,CPT-1α,ACC,LKB1,AMPK and PGC-1α(P＜0.05,P＜0.01);and increased protein expressions of myocardial LKB1,p-AMPK/AMPK and PGC-1α(P＜0.05,P＜0.01).CONCLUSION Pueraria isoflavones are protective to myocardial injury in ovariectomized rats,and the mechanism may lie in the improvement of energy metabolism-related myocardial proteins via LKB1/AMPK/PGC-1α signaling pathway.
