BACKGROUND:
Molecular subtyping is an essential complementarity after pathological analyses for targeted therapy. This study aimed to investigate the consistency of next-generation sequencing (NGS) results between circulating tumor DNA (ctDNA)-based and tissue-based in non-small cell lung cancer (NSCLC) and identify the patient characteristics that favor ctDNA testing.
METHODS:
Patients who diagnosed with NSCLC and received both ctDNA- and cancer tissue-based NGS before surgery or systemic treatment in Lung Cancer Center, Sichuan University West China Hospital between December 2017 and August 2022 were enrolled. A 425-cancer panel with a HiSeq 4000 NGS platform was used for NGS. The unweighted Cohen's kappa coefficient was employed to discriminate the high-concordance group from the low-concordance group with a cutoff value of 0.6. Six machine learning models were used to identify patient characteristics that relate to high concordance between ctDNA-based and tissue-based NGS.
RESULTS:
A total of 85 patients were enrolled, of which 22.4% (19/85) had stage III disease and 56.5% (48/85) had stage IV disease. Forty-four patients (51.8%) showed consistent gene mutation types between ctDNA-based and tissue-based NGS, while one patient (1.2%) tested negative in both approaches. Patients with advanced diseases and metastases to other organs would be suitable for the ctDNA-based NGS, and the generalized linear model showed that T stage, M stage, and tumor mutation burden were the critical discriminators to predict the consistency of results between ctDNA-based and tissue-based NGS.
CONCLUSION
ctDNA-based NGS showed comparable detection performance in the targeted gene mutations compared with tissue-based NGS, and it could be considered in advanced or metastatic NSCLC.

ObjectiveTo investigate the effect of community-based rehabilitation exercise and physical activity on the physical activity levels, functional states, and quality of life for people with mild and moderate disabilities in community settings, to ascertain the health benefits of their engagement in such fitness sports activities, anchoring in the WHO "Global Action Plan on Physical Activity 2018-2030: More Active People for a Healthier World" and the guidelines tailored for people with disabilities, using the theoretical framework and methodology of the International Classification of Functioning, Disability and Health (ICF). MethodsAligning with the WHO guidelines for people with disabilities and the ICF, a community-based rehabilitation exercise and physical activity program was designed for individuals with mild to moderate disabilities, featuring activities like fitness training (aerobic and resistance exercises), skill exercises (such as balance and coordination), as well as sports and recreational games (ball and games, etc.). A total of 230 people with mild and moderate disabilities were recruited from 20 communities in Shenzhen, with types of disabilities including physical, speech, intellectual, and mental. Professional rehabilitation fitness instructors implemented and supervised the program. The activities were of low to moderate intensity, 30 to 50 minutes per session, five times a month for six months. The community-based rehabilitation exercise and physical activity progress of these individuals was surveyed using the International Physical Activity Questionnaire (IPAQ), and their overall functioning was evaluated with WHODAS 2.0. The health-related quality of life was measured with WHOQOL-BREF. The health benefits from participation in community-based rehabilitation exercise and physical activity were assessed in terms of functioning, activity involvement, and quality of life. ResultsAfter the fitness activities, participation levels significantly increased in IPAQ domains of work-related, transport-related, domestic and gardening activity, and leisure time (|t| > 3.391, P < 0.001). The scores significantly decreased in the domains of cognition, activity, self-care, getting along, life activities and participation; and overall scores also decreased in WHODAS 2.0 (t > 6.639, P < 0.001). The scores significantly increased in the four dimensions of WHOQOL-BREF (|t| > 7.486, P < 0.001). ConclusionAfter participating in a six-month community-based rehabilitation exercise and physical activity program of mild to moderate intensity, individuals with mild to moderate disabilities have improved in physical activity and engagement levels, and the overall functioning and quality of life.

Cancer of unknown primary (CUP) is a heterogeneous tumor type that has been diagnosed as a metastatic tumor by pathological examination, but the primary tumor cannot be identified through comprehensive clinical examination. The incidence of CUP accounts for approximately 1%–2% of all tumors. CUP progresses rapidly and has a short course. The treatment and prognosis of patients with CUP are closely linked to the primary site. In clinical settings, identifying the primary tumor remains challenging. Scholars have focused on improving the detection rate. Novel technologies, such as gene expression profiling, high-throughput sequencing, epigenetics, and liquid biopsy, have been successively applied to identify the primary tumor of CUP accurately, sensitively and specifically. With the guidance of molecular diagnosis, targeted therapy, immunotherapy, and combination therapy will usher in the era of precision treatment for CUP, which may become a typical example for individualized therapy.

OBJECTIVE:
To assess the changes in the coagulation profiles of patients with chronic kidney disease (CKD) using thromboelastography (TEG) and identify the risk factors of hypercoagulation in CKD patients.
METHODS:
A total of 128 patients with CKD admitted in Hunan Provincial People's Hospital between August, 2018 and May, 2019 were recruited. The results of conventional coagulation test and TEG were compared between patients with CKD and 21 healthy control adults. The patients with CKD were divided into hypercoagulation group with a maximum amplitude (MA) > 68 mm (=66) and non-hypercoagulation group (MA≤68 mm, =62). The laboratory indicators were compared between the groups, and the factors affecting the hypercoagulable state in patients with CKD were analyzed.
RESULTS:
The levels of fibrinogen and D-Dimer increased significantly in patients with CKD at different stages as compared with the control subjects ( < 0.05). In the patients with CKD, the reaction time and K time decreased while MA, α-angle and coagulation index increased significantly in patients in stage 3-4 and those in stage 5 either with or without hemodialysis compared with the control group ( < 0.05). The estimated glomerular filtration rate (eGFR), percentage of patients with diabetes mellitus, history of stroke, percentage of neutrophils, neutrophil-lymphocyte ratio, red blood cell count, hemoglobin levels, platelet count, serum creatinine, serum cystatin-C, serum albumin, and lipoprotein (a) all differed significantly between hypercoagulation group and non-hypercoagulation group ( < 0.05). The eGFR, platelet count and hemoglobin levels were identified as independent factors affecting hypercoagulability in patients with CKD ( < 0.05).
CONCLUSIONS
s The hypercoagulable state of patients with CKD worsens gradually with the disease progression, and eGFR, platelet count and hemoglobin levels are all risk factors for the hypercoagulable state in patients with CKD.

To study the methods and principles for simultaneous treatment in the children with pectus excavatum (PE) combined with congenital cardiothoracic diseases.
Methods: The medical records of all children, who underwent simultaneous repair of PE combined with congenital cardiothoracic diseases, were retrospectively reviewed in Hunan Children's Hospital from January 2007 to September 2018. The patients were divided into a PE combined with congenital heart disease (CHD) group (n=17) and a PE combined with thoracic disease group (n=10). The repair with a custom-made sternal lifting device, a Nuss repair, were performed in the treatment of PE, and the correction of the CHD was performed by heart open surgery using cardiopulmonary bypass (through sternotomy or right infra-axillary thoracotomy) or by transcatheter closure under echocardiography or X-ray-guided percutaneous intervention in the PE combined with CHD group. The children in the PE combined with thoracic disease group underwent thoracic surgery plus Nuss procedure concurrently.
Results: All 27 pediatric patients underwent simultaneous repair of the PE combined with congenital cardiothoracic diseases. In the PE combined with CHD group, the duration of hospital stay ranged from 8.0 to 25.0 (13.2±4.8) days. Two patients had delayed healing of the surgical wound and 1 patient developed a small left pleural effusion postoperatively. In the PE combined with thoracic disease group, the duration of hospital stay ranged from 10.0 to 34.0 (19.9±7.5) days. One patient was complicated with chylothorax and 2 patients were complicated with pleural effusionin. The treatment for the patients in the 2 groups was satisfactory. No severe complications like surgical death, severe bleeding, chest organ injuries, and implant rejections were observed.
Conclusion: According to the characteristics of patients, individualized programs should be selected in order to correct children's PE combined with congenital cardiothoracic diseases in the same period, which are safe, effective and can avoid the risk of multiple operations and anesthesia, and can reduce the financial burden of family.

Objective? To explore the effects of structured hypothermia intervention program in elderly intestinal cancer patients with frailty. Methods? From November 2017 to July 2018, we selected 96 patients with surgery for intestinal cancer scored more than two points in Fried frailty assessment for the aged before surgery at the First Affiliated Hospital of Hu'nan Normal University & People's Hospital of Hu'nan Province by cluster sampling. All of the patients were divided into experimental group (n=48) and control group (n=48) with the method of random number table. Experimental group carried out the structured management model, formulated and implemented the structured hypothermia intervention program, while control group provided warm nursing based on nursing routine. We compared the respiration, blood pressure, heart rate and blood oxygen saturation before, during and after surgery as well as temperature, incidence of hypothermia and related indicators (extubation time, retention time in resuscitation room, urine volume and intraoperative blood loss) at each time points during surgery. Results were analyzed with the repeated measure variance analysis, t test and χ2 test. Results? There were interactions between time and groups in temperature, blood pressure, heart rate, respiration and blood oxygen saturation (P< 0.05). The fluctuation with time of the above vital signs in the experimental group was lower than that of control group. In experimental group, the incidence of hypothermia was lower than that in control group; the extubation time and retention time in resuscitation room were shorter than those in control group; the intraoperative blood loss was less than that in control group and the urine volume was more than that in control group;the differences were all statistically significant (P< 0.01). Conclusions? The application of structured hypothermia intervention program in elderly intestinal cancer patients with frailty can effectively maintain the stable intraoperative vital signs, shorten the time anesthesia resuscitation, reduce the incidences of hypothermia and related complications, standardize preventive measures for intraoperative hypothermia and guarantee patient intraoperative safety among elderly intestinal cancer patients with frailty.

Objective To explore the application value of surgical operation combined with neoadjuvant chemoradiation therapy for rectal carcinoma in phase Ⅱ and Ⅲ and to evaluate the effect of surgical resection. Methods A retrospective analysis was performed from January 2012 to January 2017, including 70 cases of middle and lower rectal carcinoma in phase ⅡandⅢin the First Affiliated Hospital of Hebei North University.Neoadjuvant concurrent chemoradiotherapy before operation was applied.Neoadjuvant radiotherapy: total dose 50 Gy, 2.0 Gy for once, 5 times per week, 5 weeks in total, the radiation field 5 wild for pelvic irradiation. Neoadjuvant chemotherapy: XELOX (oxaliplatin, capecitabine) / FOLFOX (oxaliplatin, leucovorin, 5-fluorouracil) was used for synchronous chemotherapy. After radiotherapy, the patients received surgery in 6-8 weeks. All the operations were performed according to the total mesorectum excision (TME) specification.Results A total of 70 patients underwent neoadjuvant concurrent chemoradiotherapy.The adverse effect rate was 15.71 % (11/70) of gradeⅠand 7.14 % (5/70) of gradeⅡ. No gradeⅢandⅣadverse reactions occurred. The tumor stage of 94.29 % (66/70) patients reduced. The TNM stage of the postoperation was decreased compared with that before neoadjuvant chemoradiotherapy (χ 2= 7.846, P < 0.05). Tumor resection rate was 94.29 % (66/70). Conclusion Surgical operation combined with neoadjuvant concurrent chemoradiotherapy before operation for middle and lower rectal carcinoma in phase ⅡandⅢhas a favorable efficacy and safety,which can alleviate the tumor staging and increase the eradication rate of tumors.
