ABSTRACT

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

ABSTRACT

After brachial plexus avulsion (BPA), microglia induce inflammation, initiating and maintaining neuropathic pain. EZH2 (enhancer of zeste homolog 2) has been implicated in inflammation and neuropathic pain, but the mechanisms by which it regulates neuropathic pain remain unclear. Here, we found that EZH2 levels were markedly upregulated during BPA-induced neuropathic pain in vivo and in vitro, stimulating pro-inflammatory cytokines (IL-1β, TNF-α, and IL-6) secretion in vivo. In rats with BPA-induced neuropathic pain, mechanical and cold hypersensitivities were induced by EZH2 upregulation and inhibited by EZH2 downregulation in the anterior cingulate cortex. Microglial autophagy was also significantly inhibited, with EZH2 inhibition activating autophagy and reducing neuroinflammation in vivo. However, this effect was impaired by inhibiting autophagy with 3-methyladenine, suggesting that the MTOR signaling pathway is a functional target of EZH2. These data suggest that EZH2 regulates neuroinflammation and neuropathic pain via a novel MTOR-mediated autophagy signaling pathway, providing a promising approach for managing neuropathic pain.

ABSTRACT

Objective To analyze the impact of canceling drug price markup policy on hospitalization expenses of urban public hospitals in Sichuan province and provide decision-making basis. Methods Data of hospitalization expenses of the top 50 diseases among inpatients discharged in 2016 and 2017 were collected, totaling 2 732 022 inpatient cases. Based on hospitalization expenses, these disease were divided into seven categories ( A-G) using dynamic clustering analysis, which represent respectively dominant diseases of different expense makeups, to compare such indicators as hospitalization expenses and composition ratios of these diseases before (2016) and after the reform (2017). Results The study found drastic changes among the medical expenses of different categories of dominant diseases. For example, per-hospitalization cost of categories E ( featuring high drug and examination expenses ) and G ( featuring balanced expenses distribution) diseases decreased since the reform, while the other categories rose instead. The proportion of drugs of different disease categories decreased to various extents. For example, category A ( high drug ratio of 5.60% ) and category E (5.15% ) diseases of which were found with the sharpest drop. Proportion of service expenses, on the other hand, rose to different extents. For example, the proportion of service expenses of all disease categories increased to varying degrees, among which category E (3.46% ), category F (3.37% ) and category D (3.36% ) accounted for the largest share of increase.Conclusions The reform is moving the cost structure of dominant diseases in Sichuan towards a rational level, yet with significant differences among disease categories. The authorities should target various categories to adjust their reimbursement policies, minimize financial burden on patients, strengthen their supervision on drug use and medical behavior, prevent such misbehaviors as the inducing demands and transferring drug markups.

ABSTRACT

Objective To identify specific peptides binding to hepatitis B virus ( HBV) DNA pol-ymerase TP region ( HBP-TP) and to study their effects on HBV replication. -ethods The phage polypep-tide display library was screened using the HBP-TP recombinant protein expressed in Escherichia coli as a substrate to obtain the specific phage, the polypeptide region of which was then sequenced. Polypeptide se-quences with a repetition rate greater than 10% were counted and commercially synthesized. Changes in HBV replication were detected after treatment of HBV-expressing cells with synthetic peptides as drugs. Re-sults Eight peptides targeting HBP-TP recombinant protein were screened out from the phage display librar-y. One of the peptides was found to have a significant inhibitory effect on HBV replication at cellular level. Conclusions A HBP-TP protein-targeting polypeptide with an inhibitory effect on HBV replication was ob-tained.

ABSTRACT

To explore the feasibility of rapid proto-typing ( RP) technology in the treatment of Standford type A aortic dissection. 5 patients with Standford type A aortic dissection received computed tomography angiography (CTA) of their aortas. The CTA images were then processed by 3D reconstruction with MIMICS16. 0 in order to create aortic dissection models through RP technology based on real patient aorta size with a ratio of 1 ∶ 1 . Accord-ing to these models, the surgeons were able to fully understand the aortic diseases of patients, thus establish indi-vidualized treatment strategies for each patient. Besides, the surgeons simulated operations on the models, which helped them achieve better results in real surgery. These patients experienced no post-operative complications and were discharged from hospital with recovery. In conclusion, RP technology can provide adequate preoperotive prep-arations for patients with Standford type A aortic dissection, improve operation efficiency and accuracy in aortic dis-section and guide precise proximal anchoring of stents during intracavitary therapy.

ABSTRACT

Objective To compare the accuracy and clinical effect between X-ray stereotactic vacuum-assisted biopsy (SVAB) and metal wire guided lumpectony.Methods From January 2010 to June 2014,681 cases of breast micro-calcification biopsy were performed.Among them,78 cases were performed with SVAB and 603 eases were performed with the method of stereotaetic metal wire guided lumpectomy.All cases were non-palpable breast lesions (NPBLs) and breast imaging-reporting and data system (BI-RADS) assessment categories 4.The diagnostic accuracy and clinical effect were compared.Results The sensitivity of both methods was 100 % with no misdiagnosis.The underestimation rate of SVAB was 12.5 %.Compared with the method of metal wire guided lumpectomy,SVAB had many advantages,such as easy to use,quickly performed,low rate of local deformation and lower rate of operative complications.77.5 % patients benefited from SVAB by avoiding open surgery of benign disease.Conclusions SVAB is an accurate,safe and convenient method of biopsy.It can be recommended as the preferred method of micro-calcification (BI-RADS 4).Additional operation should be performed on patients with the pathological diagnosis of middle and high grade of dysplasia and any kind of carcinoma.
