Objective To compare the efficacy and tolerability of the novel bowel-cleansing agent TCIC-001 and the traditional polyethylene glycol (PEG) regimen for bowel preparation prior to colonoscopy. Methods Prospective inclusion of 62 patients who were scheduled to undergo colonoscopy at Zhongshan Hospital, Fudan University from July 2021 to July 2022. They were randomly divided into TCIC-001 group (n=31) and PEG group (n=31) using a random number table method. The TCIC-001 group took TCIC-001 orally, drinking water in stages, with a total liquid intake of 1 500 mL; the PEG group took PEG orally, taking it in 4 doses, with a total liquid intake of 3 000 mL. The primary endpoint indicator is the quality of intestinal hygiene evaluated by the Boston Bowel Preparation Scale (BBPS), the secondary endpoint indicators were medication adherence, medication duration, frequency of bowel movements, duration of bowel movements, and incidence of adverse events between two groups. Results No significant differences were observed in sex, age, or defecation frequency between the two groups. For efficacy, both groups achieved equivalent bowel cleanliness, with a “good preparation” rate of 93.55% and comparable BBPS score of each intestinal segment and total scores. For tolerability, the TCIC-001 group had a shorter medication duration compared to the PEG group ([48.8±25.9] min vs [82.8±28.4] min, P<0.001), a longer defecation duration ([288.6±74.0] min vs [236.5±74.3] min, P<0.001), and a lower incidence of first defecation before medication completion (9.68% vs 41.94%, P=0.004). Regarding safety, no significant differences were observed between the TCIC-001 group and the PEG group in incidences of chloride disturbances (0% vs 9.68%) and calcium disturbances (3.23% vs 6.45%), and no other adverse events. Conclusions TCIC-001 demonstrated comparable bowel-cleansing efficacy to PEG while significantly improving tolerability (reduced medication time and lower risk of premature defecation) and maintaining favorable safety.

Objective:To evaluate the efficacy and safety of a new plasma radiofrequency generator and a disposable mucosal incision knife for endoscopic submucosal dissection (ESD) of gastrointestinal lesions.Methods:This study is a prospective, randomized, non-inferiority multicenter study (Chinese Clinical Trial Registry No.: ChiCTR2000041394). The inclusion criteria for cases are as follows: (1) being able to understand and voluntarily participate in this clinical trial, and voluntarily signing the informed consent form; (2) being 18-70 years old, regardless of gender; (3) having a gastrointestinal lesion and meeting the endoscopic treatment conditions for the indications of endoscopic submucosal dissection (ESD). The exclusion criteria are: (1) meeting the contraindications for ESD; (2) having a surgical contraindication due to coagulation dysfunction or still taking anticoagulants 1 week before surgery; (3) having coagulation dysfunction, that is, the prothrombin time is prolonged by more than 3 seconds (more than 5 seconds in patients with liver disease), or the activated partial thromboplastin time is prolonged by more than 10 seconds, and the platelet count is < 70×10?/L; (4) having severe cardiopulmonary insufficiency and being unable to tolerate the surgery; (5) being a reproductive-aged woman with a positive blood or urine pregnancy test or a lactating woman; (6) the investigator deems that there are other factors that are not suitable for inclusion or affect the subject's participation. Patients who underwent ESD treatment for gastrointestinal lesions from March 2019 to April 2023 at the Endoscopy Center of Zhongshan Hospital Affiliated to Fudan University, the Department of Gastroenterology of Minhang District Central Hospital in Shanghai, and the Department of Gastroenterology of Quzhou People's Hospital were prospectively included. The experimental group used a new plasma radiofrequency therapy instrument and a disposable mucosal incision knife, while the control group used a high-frequency electrosurgical system and a disposable mucosal incision knife. The primary efficacy indicator was the en bloc resection success rate, the secondary efficacy indicators included the coagulation success rate, and the operation stability of the plasma radiofrequency therapy instrument and the disposable mucosal incision knife; the safety indicators included the incidence of intraoperative bleeding, intraoperative perforation, and postoperative complications. Results:The study cohort comprised 194 patients, 95 in the experimental group and 99 in the control group. Analysis of the full set showed rates of en bloc resection of 97.89% (93/95) and 96.97% (96/99) in the experimental and control groups, respectively; the difference being 0.53% (-5.58%, 6.64%). Analysis of the compliance set showed rates of en bloc resection of 97.83% (90/92) and 96.88% (93/96) in the experimental and control groups, respectively; the difference being 0.58% (-5.79%, 6.94%). These data indicate that the rate of en bloc resection in the experimental group using plasma radiofrequency therapy and disposable mucosal incision was not inferior to that of the control group. The rates of achieving intraoperative coagulation in the experimental and control groups were 7.14% (5/70) and 5.97% (4/67), respectively; this difference is not statistically significant ( P=1.000). The control group had a significantly better rate of using the same instruments throughout the procedure than did the experimental group ( P<0.001). In the safety analysis set, the incidences of intraoperative and postoperative adverse events did not differ significantly between the two groups (both P>0.05). Conclusion:Plasma radiofrequency therapy equipment and a disposable mucosal incision knife are safe and effective instruments for performing ESD of gastrointestinal lesions.

Objective:To investigate the neuroprotective effect of histone deacetylase 3 (HDAC3) specific inhibitor RGFP966 on traumatic brain injury (TBI) and its mechanism in rats.Methods:Forty-eight SD rats were randomly divided into sham-operated group, TBI group, TBI+vehicle group and TBI+RGFP966 group ( n=12). Rats in the later 3 groups accepted hydraulic impact brain injury to establish TBI models; and then, RGFP966 (dissolved in 1% DMSO at a dose of 10 mg/kg) was injected intraperitoneally 30 min after modeling, twice a day for 3 d, in TBI+RGFP966 group; same amount of DMSO was injected into TBI+vehicle group at the same time. Three d after modeling, neurological function was tested by modified neurological severity score (mNSS), water content of brain tissues was detected by dry-wet weight method, proportion of injured neurons at the frontal cortical tissues on the affected side was detected by Nissl staining, expressions of HDAC3 and pyroptosis related proteins were detected by immunohistochemical staining and Western blotting, and serum content of inflammatory factors was detected by ELISA. Results:Three d after modeling, compared with the TBI+vehicle group, the TBI+RGFP966 group had significantly decreased mNSS scores (9.83±0.75 vs. 6.67±0.82), water content of the injured cerebral cortex (82.73%±0.36% vs. 80.92%±0.66%), proportion of damaged neurons (75.60%±7.44% vs. 55.87%±4.10%), and HDAC3 protein expression (0.67±0.09 vs. 0.51±0.07), and significantly increased acetylated H3 (Ace-H3) and acetylated H4 (Ace-H4) protein expressions (0.81±0.02 vs. 1.22±0.02; 0.74±0.01 vs. 1.07±0.02), and statistically decreased protein expressions of nuclear factor-κB (NF-κB, 1.20±0.05 vs. 0.94±0.04), NOD-like receptor thermal protein domain associated protein 3 (NLRP3, 0.72±0.02 vs. 0.40±0.03), Caspase-1 containing cysteine (Caspase-1), dermatin D N-terminal fragment (GSDMD-N, 0.71±0.03 vs. 0.52±0.01), significantly decreased NF-κB and NLRP3 immunohistochemical staining scores, and significantly decreased serum contents of tumor necrosis factor-α, interleukin(IL)-1β and IL-18 ( P<0.05). Conclusion:Early intervention with RGFP966 after TBI can reduce the pyroptosis and inflammatory reaction of nerve cells and play neuroprotective role, whose mechanism may be related to inhibited activation of NF-κB/NLRP3/GSDMD pathway.

Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. The systemic antitumor therapy of advanced NSCLC has undergone renovations of chemotherapy, targeted therapy and immunotherapy, which results in greatly improved survival for patients with advanced NSCLC. Immune checkpoint inhibitors (ICIs), especially targeting programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1), has changed the treatment paradigm of NSCLC. ICIs have become the standard treatment for advanced NSCLC without epidermal growth factor receptor(EGFR) mutation or anaplastic lymphomakinase(ALK) translocation in the first- or second-line setting, and for locally advanced NSCLC following concurrent radiotherapy and chemotherapy. ICIs are also promising in adjuvant/neoadjuvant therapy. More and more ICIs have been approved domestically for the treatment of NSCLC. Led by the NSCLC expert committee of Chinese Society of Clinical Oncology (CSCO), this consensus was developed and updated based on thoroughly reviewing domestic and foreign literatures, clinical trial data, systematic reviews, experts' discussion and the consensus(2019 version). This consensus will aid domestic clinicians in the treatment of NSCLC with ICIs.

Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer, most NSCLC patients are at advanced stage at the time of diagnosis. For patients without sensitive driven-oncogene mutations, chemotherapy is still the main treatment at present, the overall prognosis is poor. Improving outcomes and obtaining long-term survival are the most urgent needs of patients with advanced NSCLC. In recent years, immunotherapy has developed rapidly. Immune checkpoint inhibitors (ICIs), especially targeting programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1), have made a breakthrough in the treatment of NSCLC, beneficial to patients' survival and changed the treatment pattern for NSCLC. It shows more and more important role in the treatment of NSCLC. Led by NSCLC expert committee of Chinese society of clinical oncology (CSCO), relevant experts in this field were organized. On the basis of referring to domestic and foreign literature, systematically evaluating the results of Chinese and foreign clinical trials, and combining the experiences of the experts, the experts group reached an agreement to develop this consensus. It will guide domestic counterparts for better application of ICIs to treat NSCLC.

Objective: To evaluate the therapeutic effect of Lishi-Jianpi-Quyu decoction combined with conventional western medicine for the oral lichen planus (OLP). Methods: A total of 80 OLP patients who met the inclusion criteria were divided into two groups by random number table method, 40 in each group. The control group was treated with conventional medicine, while the research group were treated with Lishi-Jianpi-Quyu decoction on the basis of control group. Two groups were treated for 4 weeks. The severity of oral mucosal lesions was assessed by REU scale, and oral discomfort was assessed by VAS scale. The serum tumor necrosis factor-α (TNF-α), IL-6 and IL-8 levels were detected by ELISA, peripheral blood CD3⁺, CD4⁺ levels were detected by flow cytometry, and the ratio of CD4⁺/CD8⁺ was calculatedand the clinical efficacy was evaluated. Results: The effective rate of research group was 82.5% (33/40), while the control group was 62.50% (25/40), and the difference between two groups was statistically significant (χ²=9.031, P=0.003). After treatment, TNF-α (1.19 ± 0.28 μg/L vs. 3.59 ± 0.72 μg/L, t=19.807), IL-6 (11.14 ± 2.04 ng/L vs. 16.34 ± 3.20 ng/L, t=8.666), IL-8 (1.15 ± 0.61 ng/L vs. 2.04 ± 0.76 ng/L, t=5.776) of research group were significantly lower than the control group (P<0.01). The serum CD3⁺ (64.02% ± 5.16% vs. 58.07% ± 4.85%, t=5.314), CD4⁺ (41.26% ± 3.61% vs. 37.15% ± 3.04%, t=5.508), CD4⁺/CD8⁺ (1.60 ± 0.43 vs. 1.31 ± 0.40, t=3.668) of research group were significantly higher than those of the control group (P<0.01). After treatment, the REU score and VAS score in the research group were significantly lower than that in the control group (t=10.980, 11.146, P<0.01). Conclusions The Lishi-Jianpi-Quyu decoction combined with conventional western medicine can improve the clinical symptoms of OLP, reduce the level of serum inflammatory cytokines, and enhance the body's immunity and improve the curative effect.
