Purpose: The aim of this study was to understand the experience of social alienation in elderly lung cancer patients, to explore its causes, and to propose targeted intervention strategies. Methods: From July to August 2023, 16 elderly lung cancer patients attending the respiratory department of a tertiary hospital in Changsha City, Hunan Province, were selected for semi-structured interviews using a purposive sampling method. The Colaizzi 7-step method was used to analyze the data. Results: A total of four themes were distilled: the experience of social alienation in elderly lung cancer patients (pessimistic feelings, inferiority complex, and heavy psychological burden), subjective causes (disease-included shame, avoidant social behavior, and stigmatized labels), objective causes (isolated social states, and reduced amount of socialization), and rehabilitation support. Conclusion The causes of social alienation in elderly lung cancer patients include multiple aspects of personal, family, and social support, and symptom management and psychological guidance should be strengthened for this population to construct a hospitalesocietyefamily triple-linkage care program to help patients recover.

Objective:To investigate the characteristic of mild cognitive impairment (MCI) in the adults aged 48 years and over in a coal mine community, and to analyze its associated risk factors.Methods:From July to October 2019, a questionnaire survey for basic information was conducted among 180 middle-aged and elderly adults who met the inclusion criteria in the Datong coal mine community. The cognitive function was evaluated by Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The effects of gender, age, years of education, sleep, living alone, physical exercise, social activities, smoking and drinking status, body mass index and chronic diseases on cognitive level were analyzed by single factor stratification and multiple linear regression.Results:There was no significant difference in the positive rate of MCI screened by MMSE and MoCA in the age groups of 48-<64, 64-<72 and 72-90 (original and corrected P>0.05); The positive rate of MCI in MoCA screening (64.4%, 66.7%, 60.9%) was significantly higher than that in MMSE (35.6%, 45.6%, 28.1%) (all P<0.05); MMSE was positively correlated with MoCA score ( r=0.762, P<0.001). With the increase of age, the scores of memory, execution and visual space detected by MoCA decreased significantly (all P<0.05), while the scores of attention, language and orientation did not change significantly (all P>0.05). Univariate stratification showed that the significant influencing factors of MMSE or MoCA scores were gender, age, years of education and sleep status (all P<0.05). Multiple linear regression analysis showed that gender ( βMMSE=-0.192; βMoCA=-0.140), years of education ( βMMSE=0.209; βMoCA=0.328) and sleep status( βMMSE=-0.162; βMoCA=-0.136) were risk factors affecting MMSE and MoCA scores ( P<0.05). Conclusions:More middle-aged and elderly adults with MCI might be observed in a coal mine community, and the main characteristics of MCI are impaired memory, executive function and visual space. To prevent and reduce the occurrence of dementia, early interventions of MCI should be carried out among the adults with female, old age, low years of education and poor sleep quality.

Objective:To investigate the application value of three-dimensional (3D) printing technology assisted laparoscopic anatomic liver resection of segment 8 (Lap-S8).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 8 liver cancer patients including 7 cases with hepatocellular carcinoma and 1 case with intrahepatic cholangio-carcinoma who underwent 3D printing technology assisted Lap-S8 in the Hunan Provincial People′s Hospital from January 2019 to December 2020 were collected. There were 7 males and 1 female, aged from 49.0 to 80.0 years, with a median age of 56.5 years. Of the 8 patients, 6 cases underwent laparoscopic anatomic liver resection of the entire segment 8, 1 case underwent laparoscopic anatomic liver resection of ventral subsegmental of the segment 8 and 1 case underwent laparoscopic anatomic liver resection of dorsal subsegmental of the segment 8. 3D printing technology was used to assist preoperative evaluation and intraoperative navigation for all 8 patients. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination, internet or telephone interview to detect survival and tumor recurrence of patients after operation up to March 2021. Measurement data with normal distribution were represented as Mean±SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations: all the 8 patients underwent 3D printing technology assisted Lap-S8 successfully, without conversion to open surgery. The operation time, hepatic portal occlusion time and volume of intraoperative blood loss of the 8 patients were (216±41)minutes, (56±11)minutes and 75 mL(range, 50 to 300 mL), respectively. There was no intraoperative blood transfusion in 8 patients, and the surgical margin of the 8 patients was negative. (2) Postoperative situations: the duration of postoperative hospital stay of the 8 patients were (9±3)days. There was no complication such as postoperative hemorrhage, biliary fistula, liver abscess or abdominal infection occurred. (3) Follow-up: all the 8 patients were followed up for 3.0?24.0 months, with a median follow-up time of 12.5 months. During the follow-up, 1 of 8 patients with preoperative diagnosis of recurrent hepatocellular carcinoma developed tumor recurrence at 5 months after operation. The patient underwent laparoscopic surgery followed with the transcatheter arterial chemoembolization and target therapy, and survived with tumor. There was no tumor recurrence in the other 7 patients.Conclusion:3D printing technology assisted Lap-S8 is safe and feasible.

ABSTRACT OBJECTIVE：To systematically evaluate the efficacy and safety of echinococcins in the prevention of invasive candidiasis，and to provide evidence-based reference for clinical treatment. METHODS：Retrieved from PubMed，Embase， Medline，Cochrane library，CJFD，VIP and Wanfang database，randomized controlled trials（RCTs）about the effectiveness and safety of echinococcins （trial group） versus conventional fungal drugs （amphotericin B and triazole antifungal agents，control group）in the prevention of invasive candidiasis were collected during database establishment to Jul. 2019. After data extraction of clinical studies met inclusion criteria and quality evaluation with Cochrane system evaluator manual 5.0.2，Meta-analysis was performed for breakthrough invasive fungal infection rate，fungal infection mortality rate，all-cause mortality rate and the incidence of drug withdrawal due to adverse reactions by using Rev Man 5.2 statistical software. RESULTS：Totally 7 RCTs were included， involving 3 219 patients. Results of Meta-analyses indicated that the incidence of breakthrough invasive fungal infection [OR＝0.58， 95％CI（0.40，0.85），P＝0.004]，fungal infection mortality rate[OR＝0.68，95％CI（0.51，0.92），P＝0.01] and the incidence of drug withdrawal due to adverse reactions [OR＝0.52，95％CI（0.40，0.67），P＜0.001] in trial groups were significantly lower than control group，with statistical significance. There was no statistical significance in the all-cause mortality rate [OR＝0.84，95％CI（0.67， 1.05），P＝0.13]. CONCLUSIONS：Compared with amphotericin B and triazole antifungal agents，echinococcins used for the prevention of invasive candidiasis can reduce the incidence of breakthrough invasive fungal infection，fungal infection mortality rate and the incidence of drug withdrawal due to adverse reactions

Objective: To study the correlation of lifestyle characteristics with thyroid nodules in a population-based sample of centenarians in Hainan. Methods: The study was based on China Hainan Centenarian Cohort Study (CHCCS) conducted in 18 cities and counties in Hainan province from 2014 to 2016. A group of multidisciplinary team interviewed and examined local centenarians with structured questionnaires and ultrasonography procedures. A total of 918 centenarians were analyzed after excluding those who refused ultrasonographic examinations or had relevant missing data. Thyroids of centenarians were examined by 3-year experienced sonographer, details on lifestyle characteristics and dietary habits were collected by standard procedure. Results: Of the 918 centenarians, 683 (74.4%) had thyroid nodules under the ultrasonography procedures. The prevalence of thyroid nodules in different group of areca nut consumption varied significantly (P<0.05). In multivariate logistic regression model, the results showed female and areca nut intake were independently associated with thyroid nodules in centenarians (P<0.05). Conclusions The modifiable variables including areca nut intake as well as non-modifiable such as gender are independent determinants of thyroid nodules in centenarians. Further studies are warranted to explore and verify these associations in populations with different ranges of age.

With the understanding of tumor metabolism, the process and mechanism of tumor metabolic reprogramming gradually attracted much attention in recent years.Oncogenes and tumor suppressor genes are constantly changing the pathway and flux of tumor metabolism in tumorigenesis to meet the needs of tumor growth and proliferation.The role of c-MYC, TP53, HIF-1αas well as the related signal pathways in tumor metabolic reprogramming would be discussed.
