Objective:To investigate the value of transanal multipoint full-layer puncture biopsy (TMFP) in predicting pathological complete response (pCR) after neoadjuvant radiotherapy and chemotherapy (nCRT) in patients with locally advanced rectal cancer (LARC) and to establish a predictive model for providing clinical guidance regarding the treatment of LARC.Methods:In this multicenter, prospective, cohort study, we collected data on 110 LARC patients from four hospitals between April 2020 and March 2023: Beijing Chaoyang Hospital of Capital Medical University (50 patients), Beijing Friendship Hospital of Capital Medical University (41 patients), Qilu Hospital of Shandong University (16 patients), and Zhongnan Hospital of Wuhan University (three patients). The patients had all received TMFP after completing standard nCRT. The variables studied included (1) clinicopathological characteristics; (2) clinical complete remission (cCR) and efficacy of TMFP in determining pCR after NCRT in LARC patients; and (3) hospital attended, sex, age, clinical T- and N-stages, distance between the lower margin of the tumor and the anal verge, baseline and post-radiotherapy serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA)19-9 concentrations, chemotherapy regimen, use of immunosuppressants with or without radiotherapy, radiation therapy dosage, interval between surgery and radiotherapy, surgical procedure, clinical T/N stage after radiotherapy, cCR, pathological results of TMFP, puncture method (endoscopic or percutaneous), and number and timing of punctures. Single-factor and multifactorial logistic regression analysis were used to determine the factors affecting pCR after NCRT in LARC patients. A prediction model was constructed based on the results of multivariat analysis and the performance of this model evaluated by analyzing subject work characteristics (ROC), calibration, and clinical decision-making (DCA) curves. pCR was defined as complete absence of tumor cells on microscopic examination of the surgical specimens of rectal cancer (including lymph node dissection) after NCRT, that is, ypT0+N0. cCR was defined according to the Chinese Neoadjuvant Rectal Cancer Waiting Watch Database Study Collaborative Group criteria after treatment, which specify an absence of ulceration and nodules on endoscopy; negative rectal palpation; no tumor signals on rectal MRI T2 and DWI sequences; normal serum CEA concentrations, and no evidence of recurrence on pelvic computed tomography/magnetic resonance imaging.Results:Of the 110 patients, 45 (40.9%) achieved pCR after nCRT, which was combined with immune checkpoint inhibitors in 34 (30.9%). cCR was diagnosed before puncture in 38 (34.5%) patients, 43 (39.1%) of the punctures being endoscopic. There were no complications of puncture such as enterocutaneous fistulae, vaginal injury, prostatic injury, or presacral bleeding . Only one (2.3%) patient had a small amount of blood in the stools, which was relieved by anal pressure. cCR had a sensitivity of 57.8% (26/45) for determining pCR, specificity of 81.5% (53/65), accuracy of 71.8% (79/110), positive predictive value 68.4% (26/38), and negative predictive value of 73.6% (53/72). In contrast, the sensitivity of TMFP pathology in determining pCR was 100% (45/45), specificity 66.2% (43/65), accuracy 80.0% (88/110), positive predictive value 67.2% (45/67), and negative predictive value 100.0% (43/43). In this study, the sensitivity of TMFP for pCR (100.0% vs. 57.8%, χ 2=24.09, P<0.001) was significantly higher than that for cCR. However, the accuracy of pCR did not differ significantly (80.0% vs. 71.8%, χ 2=2.01, P=0.156). Univariate and multivariate logistic regression analyses showed that a ≥4 cm distance between the lower edge of the tumor and the anal verge (OR=7.84, 95%CI: 1.48-41.45, P=0.015), non-cCR (OR=4.81, 95%CI: 1.39-16.69, P=0.013), and pathological diagnosis by TMFP (OR=114.29, the 95%CI: 11.07-1180.28, P<0.001) were risk factors for pCR after NCRT in LARC patients. Additionally, endoscopic puncture (OR=0.02, 95%CI: 0.05-0.77, P=0.020) was a protective factor for pCR after NCRT in LARC patients. The area under the ROC curve of the established prediction model was 0.934 (95%CI: 0.892-0.977), suggesting that the model has good discrimination. The calibration curve was relatively close to the ideal 45° reference line, indicating that the predicted values of the model were in good agreement with the actual values. A decision-making curve showed that the model had a good net clinical benefit. Conclusion:Our predictive model, which incorporates TMFP, has considerable accuracy in predicting pCR after nCRT in patients with locally advanced rectal cancer. This may provide a basis for more precisely selecting individualized therapy.

Due to the complex components of polysorbate 80, analysis is time-consuming and labor-intensive, so there is an urgent need to find a method for rapid analysis of polysorbate 80 components.In this study, 10 batches of samples collected from 3 domestic and foreign enterprises were analyzed by UHPLC-HRMS, with the being further results were analyzed by the ExcipientProfiler software and supplemented by the extended database.The results showed that the ExcipientProfiler software could quickly identify the [M+Na]+ peak in the mass spectrogram, and obtain the information of component distribution, the numbers of components and the degree of polymerization of the sample.Meanwhile, the numbers of components obtained by the ExcipientProfiler software could be used to distinguish the injection grade samples from the ordinary grade samples by systematic clustering analysis.In addition, it was found through further supplement that the sample contained other fatty acid ester components by manually searching the relevant extended database.The polyoxyethylene sorbitan tetraoleate components were found in the sample according to the analysis of mass spectrum data.Therefore, although this method is fast and simple, it is necessary to add polyoxyethylene sorbitan tetraoleate components and other fatty acid ester components to further supplement the information in the ExcipientProfiler software, so that it can be better used for the analysis of polysorbate 80.

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.

Objective:To explore the effect of Gubi Decoction on serum related inflammatory factors and PI3K/Akt/mTOR signaling pathway in osteoarthritis model rats. Methods:Seventy SPF rats were randomly divided into the blank group, sham operation group, Glucosamine sulfate group, and the low, medium and high dose Gubi Decoction groups. Except the blank group and sham operation group, knee osteoarthritis animal models were prepared by the modified Hulth method in each group. On the 28th day after successful model preparation, the high, medium and low dose Gubi Decoction groups were given Gubi Decoction 24, 12 and 6 g/kg by gavage respectively; glucosamine sulfate group was given glucosamine sulfate tablet suspension 3 g/L by gavage, once a day for 28 days. The levels of TNF-α and IL-1β in serum were detected by ELISA. The gene expressions of PI3K, Akt and mTOR in cartilage tissue were detected by Real-PCR. The protein expressions of PI3K, Akt, p-PI3K, p-Akt and mTOR were detected by Western blot. Results:Compared with the model group, the knee joint diameter[(11.17 ± 1.81) mm, (11.60 ± 1.38) mm, (10.80 ± 1.17) mm vs. (12.57 ± 0.98) mm] of the rats in the glucosamine sulfate group and the medium and high dose Gubi Decoction groups significantly decreased ( P<0.05). The content of TNF-α [(111.43 ± 21.98) ng/L, (53.42 ± 13.25) ng/L vs. (157.89 ± 23.60) ng/L], IL-1β [(67.50 ± 18.44) ng/L, (48.22 ± 9.63) ng/L vs. (96.11 ± 14.85) ng/L] in the medium and high dose Gubi Decoction groups significantly decreased ( P<0.05), and the expression of PI3K (1.87 ± 0.17, 1.24 ± 0.49 vs. 2.19 ± 0.47), Akt (1.50 ± 0.51, 1.10 ± 0.32 vs. 2.68 ± 0.63), and mTOR (1.32 ± 0.54, 1.10 ± 0.33 vs. 2.94 ± 0.55) mRNA in the medium and high dose Gubi Decoction groups significantly decreased ( P<0.05). The expression of PI3K, Akt, p-PI3K, p-Akt in the low, medium and high dose Gubi Decoction groups significantly decreased ( P<0.05), and the expression of mTOR in the medium dose Gubi Decoction group significantly decreased ( P<0.05). Conclusion:Gubi Decoction can significantly reduce the level of inflammatory factors in the serum of osteoarthritis model rats, and its anti-inflammatory and analgesic effects may be related to PI3K/Akt/mTOR signaling pathway.

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 safety and feasibility of neoadjuvant chemotherapy prior elective surgery following self-expanding metallic stents (SEMS) for complete obstructive left hemicolon cancer. METHODS: This prospective, multicenter, open-labelled trial was approved by the Ethics Committee of Beijing Chaoyang Hospital, Capital Medical University(2016-ke-161-1) and registered in Clinicaltrials.gov (NCT02972541). INCLUSION CRITERIA: (1)age between 18 and 75 years old;(2) adenocarcinoma confirmed by pathology;(3) left hemicolon cancer confirmed by clinical manifestations and imaging examinations with the distance to anal verge > 15 cm; (4) resectable cancer evaluated by imaging examination without distant metastasis; (5) Eastern Cooperative Oncology Group (ECOG) score ≤ 1 or Karnofsky Performance Scale (KPS) > 70, indicating tolerance of neoadjuvant chemotherapy and operation; (6) absence of chemotherapy or radiotherapy within past six months; (7) bone marrow system and hepatorenal function: hemoglobin ≥ 90 g/L, neutrophil ≥ 1.5×10/L, platelet ≥ 80×10/L, total bilirubin ≤ 1.5×ULN(upper limits of normal), serum transaminase ≤ 2.5×ULN, serum creatinine ≤ 1.0×ULN, endogenous creatinine clearance rate > 50 ml/min; (8) sign for informed consent. EXCLUSION CRITERIA: (1) multiple primary colorectal cancer; (2) rejection of operation;(3) presenting peritonitis or bowel perforation before SEMS; (4) unqualified conditions proved by inspector from registration data. According to inclusion criteria, 62 consecutive patients receiving neoadjuvant chemotherapy prior to elective surgery following SEMS for complete obstructive left hemicolon cancer from Beijing Chaoyang Hospital of Capital Medical University (n=31), Qilu Hospital of Shandong University (n=14), the Third Xiangya Hospital of Central South University (n=13), Zhongnan Hospital of Wuhan University (n=2), the Fourth Hospital of Hebei Medical University (n=2) between December 2015 and December 2017 were prospectively enrolled in this study. Patients were divided into neoadjuvant chemotherapy group and elective surgery group according to the investigator's clinical experience and patient's preference. Patients in the elective surgery group received surgery within one to two weeks after SEMS placement without neoadjuvant chemotherapy. Those in the neoadjuvant chemotherapy group received 2 cycles of CapeOX or 3 cycles of mFOLFOX6 neoadjuvant chemotherapy within one to two weeks after SEMS placement, and then underwent surgery within 3 weeks after finishing neoadjuvant chemotherapy. Data between groups were compared using Student t-test, chi-square analysis or Fisher exact test analysis, including basic clinical informations, operational conditions and postoperative complications. The adverse reactions during the neoadjuvant chemotherapy were recorded. Surgical difficulty was assessed using visual analog scales ranging from 1 to 10, where 1 represented the lowest and 10 the highest degree of surgical difficulty, as judged by the surgeon. RESULTS: The study included 38 males and 24 females with mean age of (64.8±8.8) years. The clinical baseline data between 2 groups were not significantly different (all P>0.05) except the average time interval between SEMS and surgery was significantly longer in neoadjuvant chemotherapy group [(61.6±13.5) days vs. (10.4±5.2) days, t=16.679, P<0.001]. There was no stent migration in either group. Three patients had perforation in the elective surgery group; one patient had perforation and one had obstruction in the neoadjuvant chemotherapy group; and all these patients received emergent surgery. Adverse reactions of neodajuvant chemotherapy were mainly degree 1 and 2 except one patient with degree 3 diarrhea. Patients in neoadjuvant chemotherapy group had significantly lower rate of stoma [4.8%(1/21) vs. 34.1%(14/41), χ²=6.538, P=0.011], higher rate of laparoscopic surgery [71.4%(15/21) vs. 36.6%(15/41), χ²=6.751, P=0.009], shorter mean operative time (147 minutes vs. 178 minutes, t=-3.255, P=0.002), less mean intraoperative blood loss (47 ml vs. 127 ml, t=-4.129, P<0.001), lower degree of surgical difficulty(3.3 vs. 5.6, t=-5.091, P<0.001), shorter mean postoperative exhausting time (56.2 hours vs. 69.0 hours, t=-2.891, P=0.006), and shorter mean postoperative hospital stay (8.5 days vs. 13.5 days, t=-2.246, P=0.028) as compared with patients in the elective surgery group. Surgical site infection rate and anastomotic leakage rate did not differ significantly between two groups(all P>0.05). CONCLUSION Neoadjuvant chemotherapy prior elective surgery following SEMS is a relatively safe and feasible approach in the treatment for obstructive left hemicolon cancer, and is associated with less stoma, more laparoscopic surgery, shorter operative time, less blood loss, lower surgical difficulty, and faster postoperative recovery as compared with conventional elective surgery.

Objective To explore the effect of preoperative neutrophil lymphocyte ratio (NLR) on the prognosis of patients with laryngeal carcinoma.Methods Clinical data of 202 patients with laryngeal carcinoma treated from January 2004 to October 2009 were retrospective analyzed to determine the optimal critical value of NLR.To study whether NLR is an independent factor affecting the recurrence and 5-year survival rate of patients with laryngeal cancer after surgery,single factor and multivariate analyses were performed.The factors included age,gender,T stage,pathological differentiation,lymph node metastasis,primary tumor site and NLR value.The relationship between NLR and cervical lymph node metastasis was analyzed.Results The optimal critical value of NLR was 2.85,by which cases were divided into high NLR group (NLR≥2.85) and low NLR group (NLR ＜ 2.85).Single factor and multivariate analyses indicated that T staging,lymph node metastasis,primary tumor location,and NLR were the independent factors affecting the recurrence of laryngeal carcinoma.T stage and lymph node metastasis were the independent factors affecting 5-year survival rate of laryngeal carcinoma.The increase of NLR value increased the rate of cervical lymph node metastasis.Conclusion Preoperative NLR level influences the recurrence and cervical lymph node metastasis of laryngeal carcinoma and can be considered a prognosis factor of laryngeal cancer.

Objective To investigate the feasibility of a noval anterior cubital approach for the coronoid via flexor?prona?tor teres interval and assess the clinical result. Methods Five formalin?fixed adult cadaver elbows were used. Through a single universal anteromedial longitudinal skin incision, the coronoid tip was exposed via pronator and flexor carpiradialis interval, and coronoid anteromedial facet and base via palm longus and flexor carpi ulnaris interval. The distances from the entry point to the muscles or branching point of the nerves to the line passing through medial and lateral epicondyles, as well as the length were mea?sured with regard to the motor nerve branches arising from median nerve to pronator teres, flexor carpiradialis, palm longus and flexor digiti superficialis, as well as the most proximal two motor branches to flexor carpi ulnaris arising from ulnar nerve. From September 2013 to August 2014, 4 male patients with ulnar coronoid fracture were treated operatively through the above anterior cubital approach in our hospital. They were all left side involved, with an average age of 32 years (range, 16-42 years). According to O’Driscoll classification, there were two cases of type Ib and two cases IIb respectively. They were all treated by open reduction and internal fixation through flexor?pronator teres interval. Results At cubital fossa, there were 2-3 branches to the pronator teres mostly, 1 branch to flexor carpiradialis and palm longus arising from median nerve. The branch to the flexor digiti superficia?lis usually was long and thick, and divided into 2-5 short twigs near muscle. The branch to palm longus had the same trunk with that to flexor digiti superficialis. The branch to flexor digiti superficialis was the most proximal among those passed through the in?terval of pronator teres and flexor carpiradialis, and its entry point to the muscle had an averaged distance of 37.22 mm to the line passing through medial and lateral humeral epicondyles. It was optimal to expose coronoid tip through the interval of pronator teres and flexor carpiradialis. It was safe to expose coronoid proximal to the branch to flexor digiti superficialis. While, it was better to expose the anteromedial facet and base of corocoid through the interval of palm longus and flexor carpiulnaris via median and ul?nar nerve interface. All of the four patients were followed up for an average period of 9 months. They all achieved bone union from 6 weeks to 3months (mean, 9 weeks). All the patients obtained excellent result according to the modified An&Morrey elbow per?formance index with scores from 94 to 100. Conclusion The novel anteromedial cubital approach via flexor?pronator teres is opti?mal for exposure of coronoid.

BACKGROUNDBased on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.

METHODSThe Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.

RESULTSA total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).

CONCLUSIONWe first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.
