ObjectiveTo analyze the clinical characteristics and the use of traditional Chinese medicine （TCM） therapy in cancer patients with COVID-19， and to provide reference for making TCM prevention and treatment strategies and determining diagnosis and treatment priorities for patients with malignant tumors in the COVID-19 epidemic. MethodsThe medical records of 225 malignant tumor cases with COVID-19 who were admitted to 7 national research centers from January 1st to 20th， 2023 were retrospectively collected， and the main symptoms and duration after infection， nucleic acid negative conversion time， use of TCM therapy， and changes in adverse reactions after resuming anti-tumor treatment were analyzed. ResultsA total of 222 malignant tumor patients with COVID-19 were included in the analysis， involving 205 mild cases and 17 moderate cases. The top four most frequently reported clinical symptoms were fever （165 cases）， expectoration or dry cough （99 cases）， decreased appetite （95 cases） and fatigue （85 cases）， of which 40 expectoration or dry cough cases ， 37 fatigue cases and 29 decreased appetite cases lasted for more than 14 days. One hundred and five patients with nucleic acid detection report had a median negative conversion time of 14 days. The nucleic acid negative conversion time was significantly longer in patients with lung cancer compared to those with digestive system malignant tumors， and in those with myelosuppression than those without （P＜0.01）. During the infection period， 47.30% （105/222） of the patients used Chinese patent medicine， and 21.17% （47/222） were treated with herbal decoctions. The use of TCM in patients during the prevention and rehabilitation period， was 1.80%（4/222） and 7.21%（16/222）， respectively. Fifty-five patients resumed anti-tumor treatment after nucleic acid negative conversion， and received TCM simultaneously. Observed adverse reactions， including gastrointestinal reactions， bone marrow suppression， and neurotoxicity， were all grade 1 to 2， and no new adverse events occurred during follow-up. ConclusionCertain malignant tumor patients with COVID-19 had prolonged symptoms and nucleic acid negative conversion time Rational use of TCM can help to promote the rehabilitation of the patients and ensure the smooth process of anti-tumor treatment after infection.

Objective:To investigate the relationship between the number of removed lymph nodes(RLN)and patient prognosis during radical surgery for extensive cervical cancer(CC).Methods:Clinical data of 21416 pa-tients with CC who underwent radical hysterectomy between January 1,2004 to August 31,2018 in the Chinese Cervical Cancer Clinical Study was retrospectively reviewed.Restricted cubic spline(RCS)was used to analyze the dose-response relationship between the number of RLN and prognosis.The patients were divided into three groups according to the RCS and RLN number:1-17 group(8733 cases),18-26 group(8189 cases),and≥ 27 group(4494 cases).Kaplan-Meier survival analysis and Log-Rank tests were used to compare the OS rates and DFS rates between groups at 3 and 5 years.Multivariate Cox proportional hazards model was used to analyze the prognostic mortality risk.Results:① RCS results showed a U-shaped nonlinear dose-response relationship be-tween the number of RLN and prognosis(P＜0.01).When the number of RLN was less than 26,the risk of death decreased as the number of RLN increased,and the risk was lowest when the number of RLN was 26.②There were statistically significant differences(P＜0.05)in age,histological type,tumor diameter,nerve invasion,uterine invasion,vaso-lymph node space invasion,cervical invasion,number of lymph node metastasis,whether preopera-tive adjuvant therapy was received,postoperative adjuvant therapy,and whether postoperative adjuvant therapy was standardized among the 3 groups(P＜0.05).③Kaplan-Meier survival curve analysis showed that the 5-year OS of the 1-17 group,18-26 group,and ≥ 27 group were 90.23％,92.28％,and 91.61％,respectively,and the 5-year DFS were 85.32％,87.90％,and 87.18％,respectively.The differences between the three groups were sta-tistically significant(P＜0.01).④The results of multivariate Cox regression analysis showed that RLN number in the range of 1-17 was a significant risk factor for the 3-and 5-year OS and DFS,when compared to the 18-26 RLN group(HR＞1,P＜0.05).Conclusions:RLN number may be one of the prognostic indicators of CC.When the number of RLNs is between 18-26,the prognosis of the patient may be better.The number of RLN in the range of 1-17 may increase the risk of recurrence or death in CC patients.

Objective:To investigate the impact of lifestyle, apolipoprotein E (ApoE) gene, and their interaction on the risk for cognitive frailty in the elderly population in China.Methods:The study participants were from the Chinese Longitudinal Healthy Longevity Survey. The information about their lifestyles were collected by questionnaire survey, and a weighted lifestyle score was constructed based on β coefficients associated with specific lifestyles to assess the combined lifestyle. ApoE genotypes were assessed by rs429358 and rs7412 single nucleotide polymorphisms. Cognitive frailty was assessed based on cognitive function and physical frailty. Cox proportional hazards regression model was used to analyze the association of lifestyle and ApoE gene with the risk for cognitive frailty and evaluate the multiplicative and additive interactions between lifestyle and ApoE gene. Results:A total of 5 676 elderly persons, with median age [ M ( Q1, Q3)] of 76 (68, 85) years, were included, in whom 615 had cognitive frailty. The analysis by Cox proportional hazards regression model indicated that moderate and high levels of dietary diversity could reduce the risk for cognitive frailty by 18% [hazard ratio ( HR)=0.82, 95% CI: 0.68-1.00] and 28% ( HR=0.72, 95% CI: 0.57-0.91), respectively; moderate and high levels of physical activity could reduce the risk by 31% ( HR=0.69, 95% CI: 0.56-0.85) and 23% ( HR=0.77, 95% CI: 0.64-0.93), respectively. Healthy lifestyle was associated with a 40% reduced risk for cognitive frailty ( HR=0.60, 95% CI: 0.46-0.78). ApoE ε4 allele was associated with a 26% increased risk for cognitive frailty ( HR=1.26, 95% CI: 1.02-1.56). No multiplicative or additive interactions were found between lifestyle and ApoE gene. Conclusions:Dietary diversity and regular physical activity have protective effects against cognitive frailty in elderly population. Healthy lifestyle can reduce the risk for cognitive frailty in elderly population regardless of ApoE ε4 allele carriage status.
