Objective:Based on the needs of advanced nursing practice development, to establish an indicator system of role function of position of oncology genetic nurses suitable for our national condition, and to provide a basis for position establishing of nocology genetic nurses.Methods:Initial indexes were generated through the literature review and semi-structured interviews. From September to December 2022, two rounds of expert consultations and analytic hierarchy process were conducted to establish the evaluation index for role function of position of oncology genetic nurses.Results:A total of 43 experts were included in the study, the response rates of 2 rounds were 93.62%(44/47) and 97.73%(43/44), and the authority coefficients of the experts were 0.821 and 0.853. The Kendall′s coefficients of concordance for the 2 rounds of consultations were 0.100-0.150 (all P<0.01) and 0.101-0.237 (all P<0.01). Finally, the role function system of position for oncology genetic nurses was formed, which consisted of 5 first-level indexes, 17 second-level indexes and 86 third-level indexes. Conclusions:The system of role function of position for oncology genetic nurses is reasonable, scientific and reliable, professional and specific, which can provide a theoretical reference for the development of advanced nursing practice on hereditary oncology in China.

Objective:To report the long-term outcomes of Chinese rectal cancer patients after adopting a Watch and Wait (W&W) strategy following neoadjuvant therapy (NAT).Methods:This multicenter, cross-sectional study was based on real-world data. The study cohort comprised rectal cancer patients who had achieved complete or near complete clinical responses (cCRs, near-cCRs) after NAT and were thereafter managed by a W&W approach, as well as a few patients who had achieved good responses after NAT and had then undergone local excision for confirmation of pathological complete response. All participants had been followed up for ≥2 years. Patients with distant metastases at baseline or who opted for observation while living with the tumor were excluded. Data of eligible patients were retrospectively collected from the Chinese Wait-and-Watch Data Collaboration Group database. These included baseline characteristics, type of NAT, pre-treatment imaging results, evaluation of post-NAT efficacy, salvage measures, and treatment outcomes. We herein report the long-term outcomes of Chinese rectal cancer patients after NAT and W&W and the differences between the cCR and near-cCR groups.Results:Clinical data of 318 rectal cancer patients who had undergone W&W for over 2 years and been followed up were collected from eight medical centers (Peking University Cancer Hospital, Fudan University Shanghai Cancer Center, Sun Yat-sen University Cancer Center, Shanghai Changhai Hospital, Peking Union Medical College Hospital, Liaoning Cancer Hospital, the First Hospital of Jilin University, and Yunnan Cancer Hospital.) The participants comprised 221 men (69.4%) and 107 women (30.6%) of median age 60 (26-86) years. The median distance between tumor and anal verge was 3.4 (0-10.4) cm. Of these patients, 291 and 27 had achieved cCR or near-cCR, respectively, after NAT. The median duration of follow-up was 48.4 (10.2-110.3) months. The 5-year cumulative overall survival rate was 92.4% (95%CI: 86.8%-95.7%), 5-year cumulative disease-specific survival (CSS) rate 96.6% (95%CI: 92.2%-98.5%), 5-year cumulative organ-preserving disease-free survival rate 86.6% (95%CI: 81.0%-90.7%), and 5-year organ preservation rate 85.3% (95%CI: 80.3%-89.1%). The overall 5-year local recurrence and distant metastasis rates were 18.5% (95%CI: 14.9%-20.8%) and 8.2% (95%CI: 5.4%-12.5%), respectively. Most local recurrences (82.1%, 46/56) occurred within 2 years, and 91.0% (51/56) occurred within 3 years, the median time to recurrence being 11.7 (2.5-66.6) months. Most (91.1%, 51/56) local recurrences occurred within the intestinal lumen. Distant metastases developed in 23 patients; 60.9% (14/23) occurred within 2 years and 73.9% (17/23) within 3 years, the median time to distant metastasis being 21.9 (2.6-90.3) months. Common sites included lung (15/23, 65.2%), liver (6/23, 26.1%), and bone (7/23, 30.4%) The metastases involved single organs in 17 patients and multiple organs in six. There were no significant differences in overall, cumulative disease-specific, or organ-preserving disease-free survival or rate of metastases between the two groups (all P>0.05). The 5-year local recurrence rate was higher in the near-cCR than in the cCR group (41.6% vs. 16.4%, P<0.01), with a lower organ preservation rate (69.2% vs. 88.0%, P<0.001). The success rates of salvage after local recurrence and distant metastasis were 82.1% (46/56) and 13.0% (3/23), respectively. Conclusion:Rectal cancer patients who achieve cCR or near-cCR after NAT and undergo W&W have favorable oncological outcomes and a high rate of organ preservation. Local recurrence and distant metastasis during W&W follow certain patterns, with a relatively high salvage rate for local recurrence. Our findings highlight the importance of close follow-up and timely intervention during the W&W process.

BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Hepatocellular carcinoma （HCC）， an insidious malignant tumor with high incidence and lethality， poses a major threat to physical and mental health of human beings. The pathological mechanism needs to be further studied. Surgery， radiotherapy， chemotherapy， and targeted drugs are effective but induce many adverse reactions. Traditional Chinese medicine （TCM） has unique advantages and abundant clinical experience in the treatment of HCC. There has been an explosion of research on the pathways， targets， and mechanism of TCM against HCC from the perspective of molecular biology. According to previous research， Chinese medicinals or compound Chinese medicine prescriptions， directly or indirectly prevent the occurrence and progression of HCC through multiple pathways and targets， which is closely related to the pathophysiological processes such as cell proliferation， metastasis， apoptosis， autophagy， inflammatory response， and immune response. This paper summarizes and analyzes research on the action pathways and mechanisms of Chinese medicine against HCC. Specifically， isoliquiritigenin， dendrobium candidum and Yexiazhu compound Ⅱ regulate phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway to inhibit the growth， proliferation and metastasis of tumor cells. Toad venom and dioscorea zingiberensis induce and enhance HCC autophagy by modulating mammalian target of rapamycin （mTOR） signaling pathway. Myricetin， asparagus， and Biejiajian Wan regulate mitogen-activated protein kinase （MAPK） signaling pathway to promote HCC cell cycle arrest， inhibit angiogenesis， and induce apoptosis. Polygonum odoratum， tetragonum， and plantainoside modulate nuclear factor-kappa B （NF-κB） to inhibit inflammatory response and HCC metastasis and reduce drug resistance. Quercetin and erigeron breviscapus control the Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） signaling pathway to suppress epithelial-mesenchymal transition （EMT） and remodel cytoskeleton. This paper is expected to lay a theoretical basis for the in-depth research on and clinical application of Chinese medicine in the treatment of HCC.

Objective:To explore the correlation and mechanism between thalamic network abnormality and cognitive decline in patients with temporal lobe epilepsy (TLE).Methods:A total of 53 patients with unilateral TLE were consecutively enrolled through the epilepsy clinic of the First Affiliated Hospital of Guangxi Medical University from December 2018 to February 2020. During the same recruitment interval, 37 health controls(HC) with matching demographic characteristic were recruited. All subjects were received the Montreal cognitive assessment(MoCA) test and multimodal MRI scanning. Voxel-based morphometry method was used to study the changes of thalamic gray matter volume in patients with unilateral TLE. The structural covariance network and functional connectivity network based on seed points were used to analyze the changes of thalamic network in TLE patients. In addition, the correlations among abnormal thalamic structure, thalamic network and cognitive function score were analyzed. SPSS 22.0 software was used for statistical analysis. Independent sample t-test and Mann Whitney U test were used for inter group comparison. In order to explore the relationship between thalamus and thalamic network and cognitive performance in TLE patients, thalamic volume and gray matter volume and functional connection value of brain areas with abnormal synergistic changes were extracted and correlated with MoCA score. Results:The total score of MoCA in TLE patients (27.0(25.0, 29.0)) was significantly decreased compared with HC (29.0(28.0, 30.0))( Z=-4.601, P<0.001). Whole brain gray matter volume analysis showed that compared with HCTLE patients showed significant volume reduction in left cerebellum, right temporal pole, right fusiform gyrus, straight gyrus, bilateral middle temporal gyrus, thalamus, medial and paracingulate gyrus (GRF adjusted, voxel-level P<0.001 and cluster-level P<0.05). The thalamus-associated structural covariance network analysis revealed that compared with healthy controls, TLE patients exhibited decreased connectivity in right fusiform gyrus (MNI: x=28.5, y=-15.0, z=-34.5), left insula (MNI: x=-33.0, y=-18.0, z=-1.5), right middle temporal gyrus (MNI: x=55.5, y=-51.0, z=9.0), left complementary motor area (MNI: x=-10.5, y=1.5, z=57.0) and right posterior central gyrus (MNI: x=31.5, y=-33.0, z=51.0) ( P<0.001, cluster > 100). The thalamus-associated functional connectivity network analysis revealed that TLE patients exhibited decreased connectivity in left insula (MNI: x=-38, y=-7, z=-7), left lingual gyrus (MNI: x=-6, y=-81, z=-12), right lingual gyrus (MNI: x=15, y=-105, z=0) and left triangular inferior frontal gyrus (MNI: x=-39, y=36, z=-6) (GRF correction, voxel-level P<0.001 and cluster-level P<0.05). Volume of left insula which had decreased structural connectivity with thalamus were positively correlated with the MoCA score in TLE patients( r=0.279, P=0.043). Volume of left complementary motor area which had decreased structural connectivity with thalamus was positively correalated with the MoCA score and language score in TLE patients( r=0.323, P=0.018; r=0.334, P=0.015). Volume of left lingual gyrus which had decreased functional connectivity with thalamus was negatively correalated with the memory score in TLE patients ( r=-0.331, P=0.016). Conclusion:Thalamic volume, thalamic structural covariant network and functional connection network are changed in TLE patients. The abnormality of thalamic network is associated with cognitive performance in TLE patients, which may be the neural mechanism of thalamus participating in the cognitive impairment of TLE patients.

Objective: To investigate the incidence of juvenile myopia and associated factors in Nantong, to analyze the relationship between food intake and juvenile myopia, so as to provide a reference for preventing and controlling myopia of adolescents. Methods: Stratified cluster random sampling was used to select 13 schools in Nantong. A total of 3 437 students were selected for health monitoring and questionnaire survey, and the students sociodemographic characteristics and diet related information were collected. Results: The prevalence of myopia was 73.4%( n =2 522). The myopia rate of urban teenagers(74.1%) was higher than that in suburbs(72.4%), and the myopia rate of urban girls (78.2%)was higher than that of suburban girls(73.6%). Multivariate Logistic regression analysis showed that there was a significant positive correlation between the frequency of high energy food intake and myopia among urban adolescents ( OR =1.50, P <0.01). After adjusting for covariates, e.g. age, parental myopia, participation in extracurricular classes, outdoor inter class activities, the frequency of high energy food intake was significantly positively associated with myopia ( OR =1.29, P =0.03). Frequency of high energy food intake was significantly positively correlated with myopia of suburban adolescents ( OR =1.35, P =0.02). The association disappeared after adjusting for above ment ioned covariates ( P = 0.60 ). Conclusion There are differences in the main risk factors affecting the incidence of myopia between urban and suburban adolescents in Nantong. Parents, schools and the society should pay attention to adolescent myopia and high energy diet mode, pay attention to guide their reasonable eating habits, and prevent and control adolescent myopia from multiple angles.

Objective:To compare the effect of age on clinical outcome of laparoscopic sleeve gastrectomy (LSG) in the obese patients.Methods:A total of 113 patients who underwent LSG due to obesity and metabolic disorders between 2013 and 2018 at Fudan University Pudong Hospital, and completed the scheduled follow-up (1, 3, 6, and 12 months after surgery) were included for the retrospective analysis. The patients were divided into three groups based upon pre-operative age, including 15 to 30 year-old group ( n=58), 31 to 45 year-old group ( n=32), and 45 to 65 year-old group ( n=23). The body weight related parameters, glycemic and metabolic related parameters, lipid panel as well as arterial blood pressure were compared at pre-operative baseline, 1, 3, 6, and 12 months after surgery. The quantitative data were analyzed by repeated measurement ANOVA, and the P value was corrected by Bonferroni method. And the categorical variables were analyzed by chi square test. Results:The preoperative baseline data showed that with the increase of age, the preoperative body mass index gradually decreased, which were (40.1±5.9) kg/m 2, (37.1±6.6) kg/m 2 and (35.3±7.4) kg/m 2 in 16 to 30, 31 to 45 and 46 to 65 year-old groups, respectively. Otherwise, other metabolic related parameters were comparable. At 12 months after LSG, there was no significant difference in the amount of weight loss among the groups, but the percentage of total weight loss (% TWL) and the percentage of total BMI loss (%TBMIL) decreased significantly with age increasing. The %TBMIL in 16 to 30, 31 to 45 and 46 to 65 year-old groups were 32.3±7.5%, 28.4±8.4% ( P<005 compared with 16 to 30 year-old group) and 25.7±8.2% (compared with 16 to 30 year-old group P<0.001), respectively. In the patients with preoperative HbA1c>7%, HbA1c reduction in the three groups at 12 months after operation were 3.20% (compared with 46-65 year-old group P<0.001), 2.64% (compared with 46-65 year-old group P<0.05) and 1.34%, respectively. The proportions of patients with HbA1c < 6.5% were 95.8%, 88.9% and 50.0%, respectively. LDL, triglyceride and arterial blood pressure in all groups decreased and HDL increased rapidly within 3 months after operation, but there was no significant difference among the three groups. Conclusions:The improvement of blood glucose metabolism and the remission rate of type 2 diabetes mellitus (T2DM) in the patients with older age were worse than those in the younger patients, and the T2DM in the younger patients tends to obtain better clinical remission after LSG; in terms of weight loss, with the increase of age, %TWL and %TBMIL also showed a decreasing trend; however, the improvement of blood lipid and blood pressure after LSG was not affected by the factor of age. This study implies that patients who meet the indications of metabolic and bariatric surgery should be suggested to receive surgical treatment early in order to achieve better clinical outcomes.

Objective:To evaluate the 3-year survival outcomes and late injury between the self-designed patent single-channel applicator, which was modified from the traditional tandem applicator and wrapped with a oval-shield alloy around the source channel and standard Fletcher-type applicator in the high-dose-rate brachytherapy for cervical cancer.Methods:Patients initially diagnosed with cervical cancer in the Affiliated Hospital of Southwest Medical University from December 2011 to April 2017 were enrolled and randomly assigned into the external beam radiotherapy (EBRT)+ single-channel intracavitary applicator group (the patent single-channel group) and EBRT+ the Fletcher applicator group. The whole pelvis irradiation was delivered with 6-MV photons via a four-field box variant or anterior and posterior parallel fields. Five to six fractions of intracavitary brachytherapy were performed at a dose of 7 Gy at point A once a week after 30 Gy (Equivalent Dose in 2 Gy at point A: 80-90 Gy). Chemotherapy was given with intravenous injection of cisplatin at a dose of 40 mg/m 2 once weekly during EBRT. Clinical efficacy and safety were evaluated after corresponding treatment. Results:In total, 150 eligible cases were assigned into the Fletcher applicator group and 149 cases into the patent single-channel group. Up to December 2020, all patients had been followed up for 3 years, and the median duration of follow-up was 61 months. In the Fletcher group, the 3-year overall survival, progression-free survival and locoregional failure-free survival was 76.3%, 78.1% and 75.4%, and 83.8%, 80.3% and 85.5% in the single-channel group, respectively. In the Fletcher group, the cumulative rate of grade 3-4 late rectal complications was 3.3% and 6.7% in the single-channel group ( P=0.122). The cumulative rate of grade 3-4 bladder complications was 1.3% in the Fletcher group and 0.7% in the single-channel group ( P=1.000). Conclusion:The self-designed patent single-channel intracavitary applicator yields equivalent long-term clinical efficacy and safety to the standard Fletcher-type three-channel applicator in the HDR brachytherapy for uterine cervical cancer.

OBJECTIVE: To explore the effect and precautions of setting up a genetic clinic for hereditary colorectal cancers. METHODS: To collect the information of the patients who received genetic screening and genetic counseling at our hospital from January 2016 to June 2018, and analyze the role of family history collection and follow-up management. RESULTS: The detection rate of family history of tumors has increased by 13.6%. Follow up management was carried out in 156 families with hereditary colorectal cancer confirmed by detection of germline mutations. Five cases of early colorectal cancers and 12 cases of adenomatous polyps were detected and treated. CONCLUSION To set up genetic clinic is helpful to standardize the management of high-risk population, and attention should be paid to the role of family history collection and follow-up management.
