Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for circular superficial esophageal cancer.Methods:A retrospective analysis was conducted on 74 consecutive cases of circular superficial esophageal squamous cell carcinoma treated with ESD at Nanjing Drum Tower Hospital from January 2015 to December 2019. The success rate of ESD, curative resection rate, incidence of complications, and additional treatment were mainly observed.Results:One case was transferred to surgery, and the remaining 73 cases successfully completed ESD treatment. The success rate of ESD was 98.6%. Postoperative pathology of ESD revealed that 39 cases achieved curative resection, with a curative resection rate of 53.4% (39/73). Intraoperative muscle layer injury occurred in 15 cases (20.5%), and intraoperative perforation occurred in 1 case (1.4%). Two cases (2.7%) experienced delayed bleeding, and one case (1.4%) experienced delayed perforation. Eleven cases were lost to follow-up, and the remaining 62 cases received follow-up for 36.4±19.0 months. Among the follow-up cases, 12 underwent additional surgery and 5 cases additional chemotherapy and radiotherapy. Among the 57 patients with follow-up data who did not underwent surgery, 49 developed esophageal stenosis after ESD, with an incidence rate of 86.0%.Conclusion:ESD for circular superficial esophageal cancer is generally safe, but it is prone to muscle layer injury during the operation, with a low curative resection rate, a high incidence of postoperative esophageal stenosis, and a high proportion of additional surgical procedures.

Objective: To understand the current situation and regulatory effectiveness of daylighting and artificial lighting in primary and secondary school classrooms in Shanghai, so as to provide a basis for enhancing the visual environment of school classrooms. Methods: From April 2021 to December 2023, the daylighting and artificial lighting conditions of classrooms in 1 735 regular primary and secondary schools currently in operation in Shanghai were monitored, and the qualified rate of each indicator was calculated. The Chisquare test or Fisher exact probability method were used to compare the differences in qualification rates across different educational stages, regions, school type, both before and after the implementation of regulatory measures. The regulatory measures included convene interview, propaganda and education, supervision order, supervisory opinion paper, rectification requests and offenses and punishment. Results: The qualified rate of daylighting and artificial lighting in primary and secondary school classrooms was 30.1%, with a qualified daylighting rate of 85.6% and a qualified artificial lighting rate of 32.9%. There was no statistically significant differences in the qualified rate of daylighting and artificial lighting in primary and secondary schools (32.4%，28.1%；χ2=3.76，P＞0.05). However, statistically significant differences were found in the qualified rate of daylighting and artificial lighting in urban and rural school classrooms (32.6%，26.7%), as well as in public and private schools (31.4%, 20.6%) (χ2=6.99，9.92，P＜0.05). Following the implementation of regulatory measures, the qualified rate of classroom daylighting and artificial lighting improved from 30.1% to 83.2%, while the respective qualified rates of daylighting and artificial lighting increased from 85.6% to 91.1% and 32.9% to 90.5%. Compared to the preimplementation period, the qualified rate of classroom daylighting and artificial lighting, as well as the respective rates of daylighting and artificial lighting, all showed statistically significant differences after the implementation of regulatory measures (χ2=995.29，25.34，1 219.87，P<0.01). Conclusions Effective regulatory measures can promote enhanced classroom daylighting and artificial lighting. Attention should be paid to improving classroom artificial lighting, in order to provide students with enhanced visual environment.

Metastasis and resistance are main causes to affect the outcome of the current anticancer therapies. Heat shock protein 90 (Hsp90) as an ATP-dependent molecular chaperone takes important role in the tumor metastasis and resistance. Targeting Hsp90 and downregulating its expression show promising in inhibiting tumor metastasis and resistance. In this study, a redox-responsive dual-drug nanocarrier was constructed for the effective delivery of a commonly used chemotherapeutic drug PTX, and a COA-modified 4-arm PEG polymer (4PSC) was synthesized. COA, an active component in oleanolic acid that exerts strong antitumor activity by downregulating Hsp90 expression, was used as a structural and functional element to endow 4PSC with redox responsiveness and Hsp90 inhibitory activity. Our results showed that 4PSC/PTX nanomicelles efficiently delivered PTX and COA to tumor locations without inducing systemic toxicity. By blocking the Hsp90 signaling pathway, 4PSC significantly enhanced the antitumor effect of PTX, inhibiting tumor proliferation and invasiveness as well as chemotherapy-induced resistance in vitro. Remarkable results were further confirmed in vivo with two preclinical tumor models. These findings demonstrate that the COA-modified 4PSC drug delivery nanosystem provides a potential platform for enhancing the efficacy of chemotherapies.

In China, patients with hepatocellular carcinoma (HCC) are usually with late stage and long medical history when diagnosed, resulting in a lower 5-year survival rate. For advanced HCC, guidelines from different countries have different indications for local treatment. The applica-tion of hepatic artery chemoembolization has brought new treatment opportunities to patients with advanced HCC. Due to tumor heterogeneity, the response to immunotherapy is different in patients with intrahepatic recurrent lesions and extrahepatic metastatic lesions of primary hepatic carcinoma. Therefore, hepatic artery chemoembolization combined with systemic treatment is beneficial to prolong the survival of patients. The authors introduce the clinical experience of a patient with recurrent advanced HCC combined with abdominal lymph node metastasis who was treated with hepatic artery chemoembolization combined with atezolizumab plus bevacizumab. The results show that tumor is controlled in a short period with a good clinical effect.

Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.

Nerve agents are used in civil wars and terrorist attacks, posing a threat to public safety. Acute exposure to nerve agents such as soman (GD) causes serious brain damage, leading to death due to intense seizures induced by acetylcholinesterase inhibition and neuronal injury resulting from increased excitatory amino-acid levels and neuroinflammation. However, data on the anticonvulsant and neuroprotective efficacies of currently-used countermeasures are limited. Here, we evaluated the potential effects of transient receptor vanilloid 4 (TRPV4) in the treatment of soman-induced status epilepticus (SE) and secondary brain injury. We demonstrated that TRPV4 expression was markedly up-regulated in rat hippocampus after soman-induced seizures. Administration of the TRPV4 antagonist GSK2193874 prior to soman exposure significantly decreased the mortality rate in rats and reduced SE intensity. TRPV4-knockout mice also showed lower incidence of seizures and higher survival rates than wild-type mice following soman exposure. Further in vivo and in vitro experiments demonstrated that blocking TRPV4 prevented NMDA receptor-mediated glutamate excitotoxicity. The protein levels of the NLRP3 inflammasome complex and its downstream cytokines IL-1β and IL-18 increased in soman-exposed rat hippocampus. However, TRPV4 inhibition or deletion markedly reversed the activation of the NLRP3 inflammasome pathway. In conclusion, our study suggests that the blockade of TRPV4 protects against soman exposure and reduces brain injury following SE by decreasing NMDA receptor-mediated excitotoxicity and NLRP3-mediated neuroinflammation. To our knowledge, this is the first study regarding the “dual-switch” function of TRPV4 in the treatment of soman intoxication.

Objective:To investigate the effects of escitalopram oxalate combined with low dose olanzapine on negative emotion and neurological function in patients with depression.Methods:From July 2018 to January 2019, 120 depressive patients who admitted to the Affiliated Kangning Hospital of Wengzhou Medical University were prospectively selected and divided into two groups according to random number table method, with 60 cases in each group.The observation group was treated with escitalopram oxalate combined with low dose olanzapine, while the control group was treated with escitalopram oxalate.The clinical efficacy, related scale scores, neurological function indicators and adverse reactions were compared between the two groups.Results:The total effective rate in the observation group was 85.0%(51/60) at 2 months after treatment, which was significantly higher than 63.3%(38/60) in the control group(χ 2=7.350, P=0.007). At 2 months after treatment, the scores of Mini mental state examination, Hamilton anxiety scale and Hamilton depression scale in the observation group were (12.58±1.34)points, (33.27±4.32)points, (36.72±4.93)points, respectively, which were lower than those in the control group [(16.93±1.46)points, (41.82±3.95)points, (47.61±5.09)points] ( t=17.003, 11.304, 11.904, all P<0.001). At 2 months after treatment, the level of brain-derived neurotrophic factor in the observation group was (33.26±3.52)μg/L, which was higher than that in the control group [(28.27±3.43)μg/L]( t=7.864, P<0.001). The S100B protein, myelin basic protein, neuron-specific enolase levels in the observation group were (0.76±0.09)μg/L, (5.16±0.97)μg/L, (4.63±1.21)μg/L, respectively, which were lower than those in the control group [(1.31±0.12)μg/L, (7.36±0.83)μg/L, (7.72±1.69)μg/L]( t=13.348, 11.505, 28.402, all P<0.001). The incidences of adverse reactions in the control group and the observation group were 10.0%(6/60) and 13.3%(8/60), respectively, there was no statistically significant difference between the two groups(χ 2=0.323, P=0.570). Conclusion:Escitalopram oxalate combined with low dose olanzapine is effective in the treatment of depression.It can effectively improve the negative mood and neurological function of patients.
