Objective To compare the efficacy of percutaneous transforaminal approach and translaminar approach in the treatment of L5/S1 disc herniation(LDH)under endoscopic discectomy.Methods Adopted a retro-spective case-control study,and selected 62 cases of patients with L5/S1 LDH who were treated with percutaneous endoscopic surgery in the spine surgery department of our hospital from June 2020 to December 2022,and the transforaminal approach was used.(TELD)in 32 cases(TELD group),and interlaminar approach(IELD)in 30 cases(IELD group).The observation indicators included intraoperative fluoroscopy times,operation time,hospitaliza-tion days,hospitalization expenses,leg pain VAS score,ODI score,modified MacNab curative effect evaluation and complications.Results All 62 patients successfully completed the operation and follow-up,and no serious complications occurred.There were statistically significant differences in operation time,fluoroscopy times,and hospitalization expenses between the two groups(P<0.001),but there was no significant difference in hospitaliza-tion days between the two groups(P>0.05).The lower extremity VAS scores at the last follow-up and the last follow-up were significantly improved compared with those before operation(P<0.001),and the ODI scores of the two groups were significantly improved at 2 days,1 month and at the last follow-up(P<0.001).At the same time point,there was no statistical difference(P>0.05);there was no significant difference in the excellent and good rate of surgery between the two groups(P>0.05).11 patients with high iliac crest in the TELD group successfully completed the surgery.Conclusions Both the endoscopic surgery through the intervertebral foramen and the inter-laminar approach can achieve satisfactory results in the treatment of L5/S1 LDH.However,local anesthesia through the intervertebral foramen approach reduces hospitalization costs,and patients with high iliac crest can successfully complete the surgery by selecting a suitable puncture path.The translaminar approach has fewer fluoroscopy times and shorter surgical time,but there is a higher risk of dura mater and nerve damage,which requires careful opera-tion for beginners.

Objective:To compare the clinical efficacy of 1 h and 12 h getting out of bed after transradial percutaneous coronary intervention (PCI), and to provide evidence for early safe getting out of bed after PCI.Methods:The quasi-experimental method was used in this study. A total of 84 patients undergoing radial artery PCI in the Cardiovascular Center of the Affiliated Hospital of Gansu University of Chinese Medicine from July 2022 to May 2023 were selected by purpose sampling method, and were divided into the control group and the experimental group by random number table method, with 42 patients in each group. The control group was given 12 h post-operative getting out of bed activity program, and the experimental group was given 1 h post-operative getting out of bed activity program. The quality of life and self-care ability of daily life were compared before and after intervention. Besides patients′ rehabilitation satisfaction was compared after intervention.Results:Ultimately there were 42 patients in each group completed the research. In the control group, there were 24 males, 18 females, aged (66.08 ± 6.78) years old; in the experimental group there were 22 males, 20 females, aged (68.03 ± 7.17) years old. Before intervention, there were no significant differences in quality of life, self-care ability of daily life and adverse cardiac events between 2 groups (all P>0.05). After intervention, the scores of quality of life in physical function, social relationship, emotional function and environment were (77.20 ± 4.17), (42.40 ± 3.71), (68.10 ± 4.74) and (76.90 ± 4.38), respectively. Higher than (74.50 ± 3.91), (40.20 ± 3.94), (67.70 ± 3.88), (74.35 ± 3.41) in the control group, the differences between the two groups were statistically significant ( t values were 2.17-2.98, all P<0.05). The scores of daily self-care ability in grooming, eating, dressing, going to the toilet, going up and down stairs, bed chair transfer and flat walking were (4.62 ± 1.33), (6.37 ± 2.26), (8.00 ± 2.48), (6.25 ± 2.46), (4.62 ± 2.08), (10.12 ± 3.09), (10.50 ± 3.54) points, higher than the control group (4.06 ± 1.96), (5.75 ± 1.79), (6.37 ± 2.26), (5.25 ± 1.10), (3.37 ± 2.62), (8.75 ± 2.19), (8.87 ± 2.11) points. The differences between the two groups were statistically significant ( t values were 2.29-3.30, all P<0.05). The scores of rehabilitation satisfaction of experimental group in rehabilitation treatment effect, team professional level and rehabilitation treatment arrangement were (4.55 ± 0.50), (4.82 ± 0.38), (4.77 ± 0.42) points, respectively, which were higher than (4.20 ± 0.64), (4.47 ± 0.64), (4.40 ± 0.81) points of control group. The differences between the two groups were statistically significant ( t=2.69, 2.96, 2.59, all P<0.05). Conclusions:Getting out of bed 1 h after radial artery PCI is safe and effective, which can significantly improve patients′ quality of life, self-care ability and satisfaction.It is expected to be clinically promoted and trialed.

Acute pancreatitis (AP) is a common gastrointestinal disease and may lead to local complications and even multiple organ failure, and the pathogenesis of AP involves self-digestion of trypsin, inflammatory response, and microcirculation disturbance. This article introduces the role of pyroptosis in the pathogenesis of AP and briefly describes the activation pathway of pyroptosis, inflammasome, and the mechanism of action of effector molecules in inducing damage to the pancreas and extra-pancreatic organs. It is believed that the regulation of pyroptosis plays an important role in the pathogenesis of AP, which provides new ideas for the prevention and treatment of AP.

Objective To explore the prognostic value of hs-cTnⅠ in patients with suspected acute coronary syndrome(ACS)in emergency department.Methods A large-scale,prospective observa-tional study was conducted on totally 966 patients with suspected ACS admitted in Fuwai Hospi-tal from January 2017 to October 2020.Their baseline serum/plasma hs-cTnⅠ level was detected at admission,conventional treatment was performed,and relevant data were collected.Logistic regression analysis was used to predict the risk of primary and secondary endpoint events within 30 d by hs-TnⅠ concentration,and subgroup analysis was performed.Results Among the 966 patients,the time from chest pain to visit was 5.0(2.5,13.0)h,and 284 patients had primary end-point events within 30 d,including 283 cases of myocardial infarction(99.6％)at the first visit,1 case of recurrent myocardial infarction(0.4％),5 cases of cardiovascular death(1.8％),and 1 case of unplanned revascularization(0.4％).When hs-cTnⅠ was at the minimum detection limit of 2 ng/L,the incidence of adverse events was 5.8％,when the limit of 70 ng/L,the incidence was 49.2％,and when of 316 ng/L,the incidence reached 100％.The model could correctly classify 92.3％of the patients.Conclusion The hs-cTn sequence has a good predictive effect for the risk of short-term cardiovascular adverse events in Chinese population.

Precisely delivering combinational therapeutic agents has become a crucial challenge for anti-tumor treatment. In this study, a novel redox-responsive polymeric prodrug (molecular weight, MW: 93.5 kDa) was produced by reversible addition-fragmentation chain transfer (RAFT) polymerization. The amphiphilic block polymer-doxorubicin (DOX) prodrug was employed to deliver a hydrophobic photosensitizer (PS), chlorin e6 (Ce6), and the as-prepared nanoscale system [NPs(Ce6)] was investigated as a chemo-photodynamic anti-cancer agent. The glutathione (GSH)-cleavable disulfide bond was inserted into the backbone of the polymer for biodegradation inside tumor cells, and DOX conjugated onto the polymer with a disulfide bond was successfully released intracellularly. NPs(Ce6) released DOX and Ce6 with their original molecular structures and degraded into segments with low MWs of 41.2 kDa in the presence of GSH. NPs(Ce6) showed a chemo-photodynamic therapeutic effect to kill 4T1 murine breast cancer cells, which was confirmed from a collapsed cell morphology, a lifted level in the intracellular reactive oxygen species, a reduced viability and induced apoptosis. Moreover, ex vivo fluorescence images indicated that NPs(Ce6) retained in the tumor, and exhibited a remarkable in vivo anticancer efficacy. The combinational therapy showed a significantly increased tumor growth inhibition (TGI, 58.53%). Therefore, the redox-responsive, amphiphilic block polymeric prodrug could have a great potential as a chemo-photodynamic anti-cancer agent.
