Objective:To compare the clinical value of early enteral nutrition(EEN) with total parenteral nutrition(TPN) in postoperative elder patients with esophageal and cardiac cancer. Methods: 102 cases of postoperative elder patients with esophageal and cardiac cancer were randomly divided into EEN group(n=51)and TPN group(n=51).The weight loss,serum albumin, prealbumin,liver function were measured before operation and on the eighth day after operation. The anal exsufflation time, infectious complication, duration of hospital stay and treatment cost were observed. Results: The weight loss in EEN group were less than those of TPN group(P<0.05). The levels of ALT, AST, BIL and GGT in EEN group on the eighth day after operation was lower than those in TPN group(P<0.05). The anal exsufflation time and duration of hospital stay in EEN group were shorter than those of TPN group(P<0.05). The treatment cost of EEN group was significantly less than that of TPN group(P<0.05). The infectious complication rate of EEN group was lower than that of TPN group(P<0.05). Conclusion: EEN in postoperative elder patients with esophageal and cardiac cancer can decrease the postoperative infectious complication and the treatment cost, shorten the duration of hospital stay, improve nutritional status and recovery of gastrointestinal function with less side effects of liver function.

Objective:To explore the value of salivary gland imaging based on deep learning and Delta radiomics in assessing salivary gland injury after 131I treatment in post-thyroidectomy thyroid cancer patients. Methods:A retrospective analysis on 223 patients (46 males, 177 females, age(47.7±14.0) years ) with papillary thyroid cancer, who underwent total thyroidectomy and 131I treatment in Affiliated Hospital of Guilin Medical University between December 2019 and January 2022, was conducted. All patients underwent salivary gland 99Tc mO 4- imaging before and after 131I therapy. The patients were categorized according to salivary gland function based on 99Tc mO 4- imaging results (normal salivary gland vs salivary gland injury), and divided into training and test sets in a ratio of 7∶3. A ResNet-34 neural network model was trained using images at the time of maximum salivary gland radioactivity and those based on background radioactivity counts for structured image feature data. The Delta radiomics approach was then used to subtract the image feature values of the two periods, followed by feature selection through t-test, correlation analysis, and the least absolute shrinkage and selection operator( LASSO) algorithm, to develop logistic regression (LR), support vector machine (SVM), and K-nearest neighbor (KNN) predictive models. The diagnostic performance of 3 models for salivary gland function on the test set was compared with that of the manual interpretation. The AUCs of the 3 models on the test set were compared (Delong test). Results:Among the 67 cases of the test set, the diagnostic accuracy of 3 physicians were 89.6%(60/67), 83.6%(56/67), and 82.1%(55/67) respectively, with the time required for diagnosis of 56, 74 and 55 min, respectively. The accuracies of LR, SVM, and KNN models were 91.0%(61/67), 86.6%(58/67), and 82.1%(55/67), with the required times of 12.5, 15.3 and 17.9 s, respectively. All 3 radiomics models demonstrated good classification and predictive capabilities, with AUC values for the training set of 0.972, 0.965, and 0.943, and for the test set of 0.954, 0.913, and 0.791, respectively. There were no significant differences among the AUC values for the test set ( z values: 0.72, 1.18, 1.82, all P>0.05). Conclusion:The models based on deep learning and Delta radiomics possess high predictive value in assessing salivary gland injury following 131I treatment after surgery in patients with thyroid cancer.

Background and objective Gemcitabine and taxanes are effective agents commonly used in advanced squamous lung cancer. hTe best treatment sequence, however, is unclear to our knowledge. So we conducted this retrospective study in order to compare the effcacy and toxicities of ifrst-line Gemcitabine+/-platinum followed by second-line taxanes+/-platinum with the reverse sequence. Methods We totally analyzed 105 patients with stage IIIb-IV squamous lung cancer in our retrospective study. hTere were 49 patients receiving gemcitabine+/-platinum ifrst-line followed by taxanes+/-plati-num second-line (G-T group), and 56 patients receiving taxanes+/-platinum ifrst-line followed by gemcitabine+/-platinum second-line (T-G group). hTe primary endpoint of the study was overall survival (OS), and the secondary endpoints included progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) and toxicities. Results hTe me-dian OS were 18.5 mo in G-T group and 19.0 mo in T-G group (P=0.520). hTe median PFS1 was 5.0 mo and 4.0 mo with ifrst-line gemcitabine+/-platinum and taxanes+/-platinum, respectively (P=0.584). hTe median PFS2 was 2.7 mo and 2.5 mo with second-line gemcitabine+/-platinum and taxanes+/-platinum (P=0.432). hTe ORR1 of G-T group and T-G group were 36.73%and 33.92%(P=0.577), and DCR1 were 79.59%and 89.29%(P=0.186);the ORR2 of G-T group and T-G group were 4.08%and 5.36%(P=0.085), and DCR2 were 51.02%and 66.07%, respectively (P=0.118). Hematologic toxicities was more frequent in G-T group, the patients experienced more grade 3-4 lower hemoglobin (P=0.027) and thrombocytopenia (P=0.002). Conclusion hTe effcacy of ifrst line gemcitabine+/-platinum followed by second line taxanes+/-platinum and the reverse sequence was similar, and the toxicities was tolerable. Both sequential patterns were effective in advanced squamous lung cancer.

Background and objective Treatment options for patients with squamous cell carcinoma of the lung (SCC) are limited in chemotherapy. However, not all patients could benefit form standard platinum regimen. Considering the dismal prognosis of patients with advanced SCC, a greater focus on selecting sensitive chemotherapy regimens remains of up-most importance to improve outcomes in this disease. In this study, we used matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to detect pre-chemotherapy serum peptides in advanced lung squamous cell carcinoma patients accepting paclitaxel combined with platinum chemotherapy and to analyze the correlation between serum peptides and che-motherapy efcacy. Methods Patients with advanced lung squamous cell carcinoma received paclitaxel combining with plati-num chemotherapy and evaluated the efcacy every two cycles. Evaluation of complete response (CR) or partial response (PR) patients defined as sensitive group, progressive disease (PD) patients defined as resistant group. Serum samples were collected from patients with lung squamous cell carcinoma. Eighty-one patients were randomly divided into training group (sensitive group Ⅰ and resistant group Ⅰ) and validation group (sensitive group Ⅱ and resistant group Ⅱ) according to the ratio of 3:1. Se-rum samples were pretreated and Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was used to detect serum peptide fingerprints. ClinProTools software was used to analyze the differences between the sensitive group Ⅰ and the resistant group Ⅰ. Three kinds of biological algorithms (SNN, GA, QC) built in CPT software were used to establish the curative effect prediction model respectively and the optimal algorithm was selected. The validation group was used for blind verification. Results Thirty sensitive patients and 31 resistant patients were enrolled in the training group. Ten sensitive patients and 10 resistant patients were included in the validation group. The training group had 96 differentially expressed peptides in the sensitive and resistant patients, with 16 statistically significant peptides (P<0.001). The predictive model was established by 5 polypeptides (1,897.75 Da, 2,023.93 Da, 3,683.36 Da, 4,269.56 Da, 5,341.29 Da). The recognition rate of this model was 89.18% and the cross validation rate was 95.11%. The accuracy of the model was 85%, the sensitivity was 90.0% and the specificity was 80.0%. The median PFS in the sensitive group was better than patients in the resistant group (7.2 months 95%CI: 4.4-14.5 vs 1.8 months 95%CI: 0.7-3.5). The results showed that the differential peptides 4,232.04 Da and 4,269.56 Da were correlated with PFS in patients with lung squamous cell carcinoma (P<0.001). Conclusion MALDI-TOF-MS was used to detect the difference of serum peptides between sensitive and resistant groups. The preliminary curative effect prediction model was used to predict the efcacy of paclitaxel combined with platinum regimen. However, this model need further investigations to verify the accuracy and the sensitivity.

Background and objective Small-cell lung cancer (SCLC) is an aggressive disease for which the mainstay of treatment is cytotoxic chemotherapy. Despite good initial responses most patients will relapse or progress atfer the ifrst-line therapy. hTe evidence of a beneift from second-line chemotherapy is limited in patients with relapsed/advanced SCLC. Some drugs are recommended by guidelines, but more regimens are formulated based on experience in clinical. So we conducted this retrospective study in order to compare the effcacy and safety of different second-line treatment regimens. Methods We totally analyzed 309 patients received second-line treatment in our retrospective study. 157 patients received best supportive care (BSC), and the rest 152 patients received second-line chemotherapy. hTe Kaplan-Meier method survival curves and Log-rank test were used to analysis the differences among different groups. hTe endpoints were objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Results Patients administered second-line chemotherapy lived signiifcantly longer, with a total OS from ifrst-line therapy of 11.5 mo compared to 6.0 mo in patients with best supportive care alone (P<0.001), and the ORR, DCR, PFS and OS of the former (including the sensitive dis-ease and resistance/refractory disease patients) were obviously better than that of the latter. hTe ORR and DCR of the patients who received second-line chemotherapy is 39.5%and 59.2%, respectively. hTe median PFS and OS from second-line chemo-therapy were 3.3 mo and 5.3 mo. hTe patients who received second-line chemotherapy were divided by types of second-line regimens. hTe sensitive disease patients were from group A (VP-16-based rechallenge) and group B1 (CPT-11-based regimen). hTe ORR of the two groups were 48.6%and 35.3%, and the DCR were 68.6%and 58.8%, respectively. hTere was no statistically signiifcant difference (P=0.264;P=0.400). hTe median PFS from second-line chemotherapy of the two groups were 4.0 mo and 3.0 mo, and the second-line median OS were 6.5 mo and 4.5 mo. hTere was no statistic difference (P=0.432;P=0.508). hTe resistance/refractory disease patients were divided into group B2 (CPT-11-based regimen), group C (PTX/DXL-based regi-men) and group D (TPT-based regimen). hTere was no statistic difference in second-line ORR, DCR and median PFS among the three groups (P value is 0.521, 0.528 and 0.775, respectively);hTe median OS from second-line chemotherapy of the group D is longer than that of group B2 and group C, with statistical difference (P=0.043;P=0.030). hTe differences of grade III-IV hematologic toxicities among the four subgroups were not statistically different. hTe incidence of diarrhea in non-hematologic toxicities in patients who received irinotecan as second-line chemotherapy was higher than other three subgroups (P=0.029). Conclusion Patients who progressed atfer the completion of ifrst-line chemotherapy can gain survival beneift. hTe response and the PFS of the different second-line chemotherapies were similar. hTe patients who received the TPT-based regimen may gain longer overall survival than other resistance/refractory disease patients.

Fibromyalgia syndrome (FMS) is a refractory, chronic non-articular rheumatic disease characterized by widespread pain throughout the body, for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies, and some non-drug therapies, such as acupuncture, Tai Chi, and Ba-Duan-Jin, have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine (TCM) by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine, the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine, including rheumatology, psychology, acupuncture and moxibustion, and encephalopathy, with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS, mitigation of common non-specific symptoms, preferential analgesic therapy, TCM pathogenesis and treatment advantages, and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis, poor patient participation, and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems, this paper suggests that rheumatologists should serve as the main diagnostic force of this disease, and they should improve patient participation in treatment decision-making, implement exercise therapy, and fully utilize the holistic and multidimensional features of TCM, which is effective in alleviating pain, improving mood, and decreasing adverse events. In addition, it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment, which is expected to improve the standard of diagnosis and treatment of FMS in China.
