Objective To investigate the efficacy and safety of intravenous thrombolysis with low-dose and standard-dose recombinant tissue plasminogen activator(rt-PA)in the elderly patients(aged over 80 years)with acute ischemic stroke(AIS).Methods A total of 201 elderly patients with AIS treated at Tianjin Fourth Central Hospital from February 2019 to February 2023 were prospectively included and randomly assigned to the rt-PA low-dose group(n=93,0.6 mg/kg)and rt-PA standard-dose group(n=108,0.9 mg/kg).The incidence of intra-cranial hemorrhage,symptomatic intracranial hemorrhage,fatal intracranial hemorrhage,neurologic deterioration within 7 days and mortality within 90 days were observed to evaluate the safety.The neurologic improvement rate and good prognosis rate at 90 days were used to evaluate the effectiveness.A stratified analysis of 90-day outcomes was performed based on stroke severity and age.Results The incidence of intracranial hemorrhage,symptomatic intracranial hemorrhage and fatal intracranial hemorrhage within 7 days in rt-PA low-dose group was lower than that in rt-PA standard-dose group(P＜0.05).There were no statistically significant differences between the two groups concerning the residual safety index and the effectiveness index.The 90-day good prognosis rate of moderate stroke sub-group and of≥90 years of age sub-group in rt-PA low-dose group were both higher than that of rt-PA standard-dose group(P＜0.05).Conclusions For AIS patients with moderate stroke and aged over 90 years,intravenous thrombolytic therapy with rt-PA 0.6 mg/kg is recommended.

Acute ischemic stroke (AIS) is a kind of central nervous system disease that seriously threatens human health and life. Current treatment for AIS is mainly reperfusion. However, the time-sensitive of reperfusion limits its clinical application, and a considerable part of patients within the time window cannot achieve the expected effect after reperfusion; related complications of reperfusion have not been completely solved. So far, some clinical trials have confirmed that neuroprotectants are useful supplements and adjuncts to reperfusion. This paper reviews the recent advance in neuroprotectants combined with reperfusion in AIS to provide references for AIS treatment.

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5％vs 28.6％,70.6％vs 32.1％,58.8％vs28.6％,29.4％vs3.6％,29.4％vs 3.6％,P＜0.05),MCD were more frequently found(58.8％vs 10.7％,P=0.001),GCB were rarely found(17.6％vs 50.0％,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P＜0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P＜0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.

OBJECTIVE: Xiaotan Sanjie recipe (XTSJ), a Chinese herbal compound medicine, exerts a significant inhibitory effect on gastric cancer (GC) metastasis. This work investigated the mechanism underlying the XTSJ-mediated inhibition of GC metastasis. METHODS: The effect of XTSJ on GC metastasis and the associated mechanism were investigated in vitro, using GC cell lines, and in vivo, using a GC mouse model, by focusing on the expression of Glc-N-Ac-transferase V (GnT-V; encoded by MGAT5). RESULTS: The migration and invasion ability of GC cells decreased significantly after XTSJ administration, which confirmed the efficacy of XTSJ in treating GC in vitro. XTSJ increased the accumulation of E-cadherin at junctions between GC cells, which was reversed by MGAT5 overexpression. XTSJ administration and MGAT5 knockdown alleviated the structural abnormality of the cell-cell junctions, while MGAT5 overexpression had the opposite effect. MGAT5 knockdown and XTSJ treatment also significantly increased the accumulation of proteins associated with the E-cadherin-mediated adherens junction complex. Furthermore, the expression of MGAT5 was significantly lower in the lungs of BGC-823-MGAT5 + XTSJ mice than in those of BGC-823-MGAT5 + solvent mice, indicating that the ability of gastric tumors to metastasize to the lung was decreased in vivo following XTSJ treatment. CONCLUSION XTSJ prevented GC metastasis by inhibiting the GnT-V-mediated E-cadherin glycosylation and promoting the E-cadherin accumulation at cell-cell junctions.

Objective:To reveal the regular pattern characteristics of different diseases with the same treatment in the most common diseases with blood stasis syndrome; To provide reference for the clinical treatment of blood stasis syndrome and the development of new drugs.Methods:RCTs of blood stasis syndrome were retrieved from CNKI, Chongqing VIP, Wanfang Data, SinoMed, and China Medical Journal Full-text Database from the establishment of the databases to December 31, 2022. Diseases, accompanied symptoms, prescriptions and medicines were extracted. The diseases with the highest frequency among the three disease systems with the highest frequency were collected, and their medication characteristics and prescription rules were analyzed using frequency statistics and association rules Apriori algorithm. The core prescriptions of blood stasis syndrome of three kinds of diseases were excavated and their network similarity was analyzed.Results:A total of 2 052 articles were included. Stable coronary heart disease, ischemic stroke and DN were more common diseases with blood stasis syndrome. The common drugs for the three diseases were Chuanxiong Rhizoma, Carthami Flos, Persicae Semen, Angelicae Sinensis Radix. The core prescription of stable coronary heart disease was Persicae Semen- Carthami Flos- Chuanxiong Rhizoma- Angelicae Sinensis Radix- Paeoniae Radix Rubra; the core prescription of ischemic stroke is Buyang Huanwu Decoction; the core prescription of DN was Persicae Semen- Carthami Flos- Chuanxiong Rhizoma- Angelicae Sinensis Radix- Cornus Officinalis- Dioscoreae Rhizoma- Astragali Radix. The similarity between stable coronary heart disease and ischemic stroke core prescription network was 0.35, the similarity between ischemic stroke and DN core prescription network was 0.29, and the similarity between stable coronary heart disease and DN core prescription network was 0.26. Conclusions:The theory of "different diseases with the same treatment" can profoundly guide clinical practice. The core medicines of blood stasis syndrome are Persicae Semen, Carthami Flos, Angelicae Sinensis Radix, and Chuanxiong Rhizoma. On this basis, combined with different diseases and syndromes to make changes of adding and subtracting.

This study combined the herbal pair Platycodonis Radix-Curcumae Rhizoma(PR-CR) possessing an inhibitory effect on tumor cell proliferation and metastasis with the active component of traditional Chinese medicine(TCM) silibinin-loaded nanoparticles(NPs) with a regulatory effect on tumor microenvironment based on the joint effect on tumor cells and tumor microenvironment to inhi-bit cell metastasis. The effects of PR-CR on the cellular uptake of NPs and in vitro inhibition against breast cancer proliferation and metastasis were investigated to provide an experimental basis for improving nanoparticle absorption and enhancing therapeutic effects. Silibinin-loaded lipid-polymer nanoparticles(LPNs) were prepared by the nanoprecipitation method and characterized by transmission electron microscopy. The NPs were spherical or quasi-spherical in shape with obvious core-shell structure. The mean particle size was 107.4 nm, Zeta potential was-27.53 mV. The cellular uptake assay was performed by in vitro Caco-2/E12 coculture cell model and confocal laser scanning microscopy(CLSM), and the results indicated that PR-CR could promote the uptake of NPs. Further, in situ intestinal absorption assay by the CLSM vertical scanning approach showed that PR-CR could promote the absorption of NPs in the enterocytes of mice. The inhibitory effect of NPs on the proliferation and migration of 4T1 cells was analyzed using 4T1 breast cancer cells and co-cultured 4T1/WML2 cells, respectively. The results of the CCK8 assay showed that PR-CR-containing NPs could enhance the inhibition against the proliferation of 4T1 breast cancer cells. The wound healing assay indicated that PR-CR-containing NPs enhanced the inhibition against the migration of 4T1 breast cancer cells. This study enriches the research on oral absorption of TCM NPs and also provides a new idea for utilizing the advantages of TCM to inhibit breast cancer metastasis.

Objective:To investigate the efficacy and safety of recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis combined with edaravone dexborneol at different timing in super elderly patients (aged≥85 years) with moderate to severe acute ischemic stroke (AIS).Methods:A prospective study was performed. Seventy-one super elderly patients with moderate to severe AIS treated with rt-PA intravenous thrombolysis combined with edaravone dexborneol from December 2020 to March 2023 in Department of Neurology, Affiliated Fourth Central Hospital of Nankai University were selected and randomly divided into early group ( n=35) and advanced group ( n=36); patients in the early group were given edaravone dexborneol immediately after rt-PA intravenous thrombolysis, and patients in the advanced group were given edaravone dexborneol 24 h after rt-PA intravenous thrombolysis. In addition, 31 patients with moderate to severe AIS received rt-PA intravenous thrombolysis only in Department of Neurology of the hospital from August 2018 to December 2020 were selected as control group. Differences in efficacy and safety indexes among the 3 groups were compared. Results:After 7 d of treatment, the improvement rate of neurological function in early group was significantly higher than that in control group and advanced group ( P<0.05). After 90 d of treatment, modified Rankin scale (mRS) scores in early group were statistically lower than those in control group and advanced group ( P<0.05); good prognosis rate in early group was statistically higher than that in control group and advanced group ( P<0.05). The incidences of intracranial hemorrhage and symptomatic intracranial hemorrhage in early group were significantly lower than those in control group and advanced group ( P<0.05). After 30 and 90 d of treatment, the advanced group had significantly lower mortality than the control group, but significantly higher mortality than the early group ( P<0.05). Conclusion:Edaravone dexborneol immediately after rt-PA intravenous thrombolysis is the optimal timing for super elderly patients with moderate to severe AIS, which can improve the efficacy and safety.

OBJECTIVE: To evaluate the relevant indicators affecting difficulty in the extraction of impacted mandibular third molars and score difficulty of different operation and risk indicators, so as to build an intuitive and accurate scale to help operators make more accurate analysis and prediction of difficulty before the operation. METHODS: Based on literature and the clinical review, the difficulty indicators of tooth extraction were summarized. Firstly, 10 doctors from Peking University School and Hospital of Stomatology who had been engaged in alveolar surgery for a long time established an expert nominal group, and then rated whether the summarized indicators needed to be retained in the form of face-to-face questionnaires. A level 1 and 2 item frame for evaluating difficulty in the tooth extraction was formed after discussion; Then Delphi method was used to send a questionnaire to 30 experts by e-mail. After two rounds of scoring and modification, the scale of difficulty in the extraction of impacted mandibular third molars was formed. RESULTS: The recycling rate of two rounds of questionnaires was 100.0%, which showed that the experts were very enthusiastic about the study; The authority coefficients (Cr) of the two rounds of Delphi expert consultation were both 0.92, which showed that the results were representative and authoritative. After two rounds of grading and revision, the variable coefficient (CV) decreased and the Kendall's concordance coefficient (W) increased, which were statistically significant: In the first round, the CV was 0.24 and W was 0.56 (P < 0.001), and in the second, the CV was 0.19 and W was 0.72 (P < 0.001), which indicated that there was a good convergence among the expert opinions. Finally, a scale of difficulty in the tooth extraction containing 12 items at level A and 37 items at level B was formed, including operation difficulty indicators, risk difficulty indicators and common difficulty indicators. CONCLUSION Based on comprehensive literature retrieval, the study has put forward the concept that difficulty in the extraction of impacted mandibular third molars is composed of operation difficulty and risk difficulty. Using Delphi method, the long-term clinical experience and professional knowledge of experts are transformed into quantitative indicators as a scoring scale. The scale has certain representativeness and authority.

BACKGROUND: Core muscle functional strength training (CMFST) has been reported to reduce injuries to the lower extremity. However, no study has confirmed whether CMFST can reduce the risk of low back pain (LBP). OBJECTIVE: This study identified the effects of CMFST on the incidence of LBP in military recruits. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: We performed a prospective, open-label, randomized, controlled study in a population of young healthy male naval recruits from a Chinese basic combat training program. Participants were randomly assigned to either the core group or the control group. In additional to normal basic combat training, recruits in the core group underwent a CMFST program for 12 weeks, while recruits in the control group received no extra training. MAIN OUTCOME MEASURES: At the beginning of the study and at the 12th week, the number of participants with LBP was counted, and lumbar muscle endurance was measured. In addition, when participants complained of LBP, they were assessed using the visual analog scale (VAS) and Roland Morris Disability Questionnaire (RMDQ). RESULTS: A total of 588 participants were included in the final analysis (295 in the core group and 293 in the control group). The incidence of LBP in the control group was about twice that of the core group over the 12-week study (20.8% vs 10.8%, odds ratio: 2.161-2.159, P < 0.001). The core group had better lumbar muscle endurance at 12 weeks than the control group ([200.80 ± 92.98] s vs [147.00 ± 84.51] s, P < 0.01). There was no significant difference in VAS score between groups, but the core group had a significantly lower RMDQ score at week 12 than the control group (3.33 ± 0.58 vs 5.47 ± 4.41, P < 0.05). CONCLUSION This study demonstrated that the CMFST effectively reduced the incidence of LBP, improved lumbar muscle endurance, and relieved the dysfunction of LBP during basic military training.

The postictal state refers to the abnormal condition occurring between the end of an epileptic seizure and return to baseline condition,including a variety of cognitive, motor, sensory, autonomic, mental and behavioral impairments. The symptoms which may last from seconds to days are various and the severity is different. It also may exert great impact on patients′ health and quality of life. However, the lack of relevant studies at home and abroad, along with the absence of correct understanding of this in clinical practice, may lead to frequent misdiagnosis and mistreatment. This article will review the concepts, pathophysiological mechanisms, clinical manifestations, diagnosis, differential diagnosis, clinical significance and intervention strategies, aiming at deepening the understanding of the phenomenon, as well as providing references for further clinical research.
