OBJECTIVE To investigate the efficacy and safety of tirofiban for early neurological deterioration in patients with acute ischemic stroke. METHODS A total of 126 patients with early neurological deterioration of acute ischemic stroke who were admitted to the Department of Neurology， Heji Hospital Affiliated to Changzhi Medical College from January 2022 to December 2023 were selected and divided into observation group and control group according to random number table method， with 63 cases in each group. All patients received standardized treatment such as lipid-lowering and blood pressure-lowering therapy. Based on the standard treatment， patients in the control group additionally took Aspirin enteric-coated tablets 100 mg+Clopidogrel bisulfate tablets 75 mg orally （once a day， for 14 consecutive days）. The patients in the observation group received Tirofiban hydrochloride and sodium chloride injection based on the standardized treatment [first intravenous infusion of 0.40 μg/（kg·min） for 30 min， and then continuous intravenous infusion of 0.10 μg/（kg·min） for 47.5 h]； subsequently， patients were given Aspirin enteric-coated tablets （100 mg） and Clopidogrel bisulfate tablets （75 mg） once a day for 14 consecutive days. The clinical efficacy， the National Institutes of Health Stroke Scale （NIHSS） score， modified Rankin Scale （mRS） score， and hemorheological indexes before and after treatment were compared between the two groups， and the adverse reactions were recorded. RESULTS The total effective rate （87.30%） of the observation group was significantly higher than that of the control group （71.43%） （P＜0.05）. NIHSS scores of the two groups at 1st， 7th and 14th day after treatment， the mRS score at 90th day after treatment， and the platelet aggregation rate， whole blood viscosity， plasma viscosity and fibrinogen at 14th day after treatment were significantly lower than those before treatment in the same group， and the observation group was significantly lower than the control group at the same period （P＜0.05）. The total incidences of adverse reactions such as nausea， headache， fever， gastrointestinal bleeding， oral and nasal mucosal bleeding and thrombocytopenia in both groups of patients were 28.57% respectively， with no statistically significant difference （P＞0.05）. CONCLUSIONS For patients with early neurological deterioration in acute ischemic stroke， the addition of tirofiban can accelerate the recovery of neurological function， improve blood hyperviscosity and platelet aggregation， and improve the prognosis of patients with good safety.

Objective To explore the effects and mechanisms of Changpu Yujin Tang(CPYJT)on the NOD-like receptor thermal protein domain associated protein 3/cysteinyl aspartate specific proteinase-1/Gasdermin D(NLRP3/Caspase-1/GSDMD)signaling pathway-mediated neuroinflammation in rats with Tourette syndrome(TS).Methods SPF-grade male SD rats were randomly divided into the Control and TS groups.After successful modeling in the TS group,the rats were randomly divided into the Model,Tiapride,and CPYJT groups,and were treated with the corresponding drugs for 4 weeks.After the treatment,the rats' behavior was scored,H & E staining was used to observe pathological changes in the striatum,ELISA was used to measure the content of IL-1β and IL-18,RT-qPCR was used to detect the expression of NLRP3 and ASC mRNA,and Western blot was used to detect the expression of NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins.Results Compared with the Control group,the Model group showed increased scores of stereotyped and motor behaviors(P＜0.01),pathological changes in the striatal tissue,increased content of IL-1β and IL-18(P＜0.01),and upregulated expression of NLRP3,ASC mRNA,and NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins(P＜0.01).Compared with the Model group,the Tiapride group and the CPYJT group showed decreased scores of stereotyped and motor behaviors(P＜0.01),improved pathological damage in the striatal tissue,reduced content of IL-1β and IL-18(P＜0.01),and inhibited expression of NLRP3,ASC mRNA,and NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins(P＜0.01).Conclusion The therapeutic effect of CPYJT on TS is related to the inhibition of the neuroinflammatory response mediated by the NLRP3/Caspase-1/GSDMD signaling pathway.

OBJECTIVE To investigate the roles and mechanisms of γ-bungarotoxin(γ-BGT)in inducing respiratory distress in mice.METHODS Six male Kunming mice were selected and anesthe-tized before tracheal intubation and respiratory recording.After stabilizing respiration,the mice were intraperitoneally injected with γ-BGT at a dose of 6 mg·kg-1.Once a decrease in respiratory frequency was observed,the mice were intravenously injected with nikethamide at a dose of 12.5 mg·kg-1.Respi-ratory frequency was monitored using the BL420 signal acquisition and processing system.Male Kunming mice were randomly divided into the normal control group(saline,ip),γ-BGT group(6 mg·kg-1,ip),and γ-BGT+nikethamide group(γ-BGT 6 mg·kg-1,ip,followed by nikethamide 12.5 mg·kg-1,ip,when shal-low breathing and enhanced abdominal respiration were observed).The levels of Glu and GABA in the medulla oblongata were measured using ELISA.The protein expression levels of GAD65 and GAD67 in the medulla oblongata were determined by Western blotting.Primary mouse medullary neurons were cultured in vitro and divided into the following groups:cell control group,γ-BGT group,carbachol group,gallamine group,γ-BGT+H-89 group,and γ-BGT+Y-27632 group.The γ-BGT group,carbachol group,and gallamine group were incubated with γ-BGT(40 mg·L-1),carbachol(100 mmol·L-1),and gallamine(100 mmol·L-1),respectively,for 4 h.The γ-BGT+H-89 and γ-BGT+Y-27632 groups were pretreated with γ-BGT(40 mg·L-1)for 4 h,followed by incubation with the protein kinase A(PKA)inhibitor H-89(50 mmol·L-1)and the Ca2+channel inhibitor Y-27632(50 mmol·L-1)for another 2 h,respectively.ELISA was used to measure the levels of Glu,GABA,cAMP,and calpain in the primary mouse medul-lary neurons.Western blotting was employed to assess the protein expression levels of GAD65 and GAD67,and PKA phosphorylation levels.Fluo-4 fluorescent probe was used to detect the intracellular Ca2+level.RESULTS The respiratory rate of mice significantly decreased after iv administration of γ-BGT(γ-BGT group)(P<0.05).After treatment with nikethamide(nikethamide group),the respiratory rate significantly recovered(P<0.05).Compared with the normal control group,the γ-BGT group exhib-ited a significant decrease in Glu content(P<0.05),a significant increase in GABA content(P<0.05),and a significant decrease in the Glu/GABA ratio.Additionally,the protein expression levels of GAD65 and GAD67 were significantly elevated(P<0.05).Compared with the γ-BGT group,the γ-BGT+niketh-amide group showed a significant increase in Glu content(P<0.05),a significant decrease in GABA content(P<0.05),a significant increase in the Glu/GABA ratio,and a significant reduction in GAD65 and GAD67 protein expression levels(P<0.05).Compared to the cell control group,the γ-BGT group demonstrated a significant decrease in Glu content(P<0.05),a significant increase in GABA content(P<0.05),and a significant reduction in the Glu/GABA ratio.Furthermore,the protein expression levels of GAD65 and GAD67 were significantly elevated(P<0.05).Additionally,cAMP content,PKA phosphor-ylation levels,Ca2+levels,and calpain activity were all significantly increased(all P<0.05).Glu,GABA,Glu/GABA ratio,and GAD expression levels in the γ-BGT group changed in the same way as in the gallamine group;In the γ-BGT+Y-27632 group,calpain activity and expression levels of GAD65 and GAD67 were all significantly decreased(all P<0.05).In the γ-BGT+H-89 group,Ca2+levels and calpain activity were significantly reduced(all P<0.05).CONCLUSION γ-BGT-induced poisoning can lead to respiratory distress in mice,possibly through the antagonism of M2 muscarinic acetylcholine receptors in medullary neurons,activation of the cAMP/PKA signaling pathway,elevation of intracellular Ca2+levels,and increased expression and activity of GAD,resulting in an imbalance of Glu and GABA in the medulla.

Objective Through reviewing the herbs,medical books and classic prescriptions of the past dynasties,the herbal examination of Gypsum fibrosum and its analogs was carried out to clarify the relationship between them.The qualitative analysis was carried out by single-point Raman,infrared,near infrared and XRD techniques,the quantitative analysis of the main components was carried out by EDTA titration and Raman surface scanning technique,the elemental analysis was carried out by ICP-OES,and the differences between gypsum and argillite were observed by scanning electron microscope.Results Gypsum fibrosum is mixed with marble,feldspar,north cold-water stone,south cold-water stone and xuanjing stone and so on.Before the Ming Dynasty,there was no differentiation between soft and anhydrite,and after the Ming Dynasty,it was clear that gypsum was soft gypsum and feldspar was anhydrite;in modern times,marble is also made to be gypsum for medicinal use;Feldspar is anhydrite and is no longer made to be used for medicinal use,north cold-water stone is red gypsum,and south cold-water stone is calcite.Gypsum,south coldwater stone is calcite.The peaks of argillite appeared to be buried in the Raman spectrum compared with Gypsum fibrosum,and the original profiles of both infrared and near-infrared were basically the same,and the near-infrared model established by the preprocessing method of the first-order derivatives plus vector normalization(5-point smoothing)could effectively differentiate between Gypsum fibrosum and its analogues,but it could not differentiate between argillite and Gypsum fibrosum with high content.XRD showed that there are differences in the relative intensities of the peaks of argillite and Gypsum fibrosum,and some XRD shows that there are differences in the relative intensities of the peaks of basalt and Gypsum fibrosum,and some of the peaks of basalt are characterized by impurities such as quartz,and the contents of trace elements such as Fe,Mn,Cr,Pb,Hg and As are higher in basalt.The peak shapes of XRD,Raman spectra,infrared spectra and near-infrared spectra of Gypsum fibrosum and calcined gypsum are closer but can still be distinguished,and the Ca content of calcined gypsum is higher than that of gypsum.Commercially available south chrysocolla and stalactite source are carbonate minerals calcite calcite.Spectral detection can not be distinguished,the trace element content is basically the same,but the traits are different.North chrysocolla(red gypsum)is higher than the Fe content of commercially available white gypsum.Raman surface scanning not only can be a qualitative and quantitative determination of minerals such as gypsum and other minerals,and the results of the content of the titration is basically similar,but also to determine the state of Gypsum fibrosum and calcined gypsum calcined water loss status and the degree of calcined gypsum.The results of Raman surface scanning are similar to the titration results.Conclusion This study can provide a scientific basis for the traceability of Gypsum fibrosum,and can better guide the clinical use of medicine and the rational use of resources.

Objective:To investigate the characteristics and clinical effects of laparoscopic pneumovesical Cohen and laparoscopic Lich-Gregoir ureteral replantations for the treatment of primary obstructive megaloureter (POM) in children.Methods:A randomized controlled study was conducted.The clinical data of 51 children with unilateral POM admitted to the First Affiliated Hospital of Zhengzhou University from October 2018 to October 2023 were collected.Random number table method was used in the selection of surgical methods.They were divided into the laparoscopic pneumovesical Cohen ureteral replantation group (group A, 22 cases) and the laparoscopic Lich-Gregoir ureteral replantation group (group B, 29 cases) according to the surgical method.The anterior-posterior diameter(APD), maximum ureteral diameter and differential renal function parameters on the affected side were measured by color Doppler ultrasound of the urinary system, and compared between and within the two groups before and after surgery.The operation time, blood loss and postoperative intubation time were compared between the two groups.The incidence of postoperative complications such as reflux, bladder spasm, urinary retention and urinary tract infection was recorded.The independent and paired sample t-tests were used for statistical analysis. Results:The operation time and hematuria duration of group B [(125.7±14.2) min, (1.5±0.6) d] were significantly shorter than those of group A [(142.6±14.7) min, (2.8±0.7) d] (all P<0.05). The APD, maximum ureteral diameter, and differential renal function on the affected side of group A were (21.7±7.9) mm, (11.6±3.2) mm, and (28.2±4.9)% before surgery, and (10.3±4.5) mm, (6.0±2.0) mm and (43.8±4.4)% after surgery, respectively.The APD, maximum ureteral diameter, and differential renal function on the affected side of group B were (21.1±5.6) mm, (11.3±4.6) mm, and (30.2±5.5)% before surgery, and (10.2±4.5) mm, (6.6±2.0) mm, and (42.4±5.2)% after surgery, respectively.There was no statistically significant difference in the values of APD, maximum ureteral diameter, and differential renal function before and after surgery between the two groups of children (all P>0.05). However, there were statistically significant differences in the values of APD, maximum ureteral diameter, and differential renal function before and after surgery between the same group of children (all P<0.01). No significant difference was found in intraoperative blood loss, postoperative intubation time, and postoperative complications between the two groups (all P>0.05). Conclusions:Both surgical methods are effective in the treatment of POM in children.Laparoscopic Lich-Gregoir ureteral replantation has advantages of less operation time compared with laparoscopic pneumovesical Cohen ureteral replantation.

Objective:To investigate the application status of emergency radiology in China, and to provide data support for the standardized development, scientific management and big data research of emergency radiology.Methods:From August 12th to October 19th, 2022, a questionnaire survey was conducted through WeChat"Questionnaire Star"to send targeted questionnaires to investigate the relevant data of the current status of emergency radiology in China, mainly including digital radiography (DR) and computed tomography (CT). This study was initiated by the Chinese Emergency Radiology Database Collaboration Group, and comprehensively investigated emergency imaging personnel, equipment, workload, critical value reporting process, and artificial intelligence (AI) application status.Results:There were 123 hospitals in the study. The survey showed that emergency DR/CT reports were mainly completed by residents and above (69.1%). There were 21 DR brands, 10 CT brands and 8 MR brands used for emergency imaging examinations. The median number of DR examinations in tertiary hospitals and secondary hospitals investigated from January to June 2022 was 4 642 and 2 015 cases respectively, and the median number of CT examinations was 16 512 and 3 762 cases respectively. The average single-shift workload of DR in the emergency radiology department during the day and night shift in tertiary hospitals was mainly ≤20 copies and 21-50 copies, and the average single-shift workload of CT in the emergency radiology department during the day and night shift was mainly 21-50 copies and 51-100 copies, while the average single-shift workload of DR/CT in the emergency radiology department during the day/night shift in secondary hospitals was mainly ≤20 copies. In terms of critical value reporting process, 74.8% of emergency imaging doctors and 84.6% of emergency imaging technicians took the way of phone/text message to notify the clinical doctor or the patients′ family. The overall deployment rate of AI in emergency imaging was about 60.2%. 75% of the respondents believed that in the future, AI can improve emergency radiology work from aspects such as emergency screening, aided diagnosis and process optimization.Conclusions:The emergency medical imaging mainly based on DR and CT has the current situations such as generally low seniority of doctors, diverse brands of imaging equipments, large volume of examinations and intense workload per doctor, especially in tertiary hospitals, and dependence on traditional means for critical value reporting. At present, AI is emerging in the field of emergency imaging, and there is still a long way to go to play the huge potential of AI in the intelligent whole process of emergency imaging in the future.
