[Objective]To do textual research on the meaning of"Fanteng"(烦疼)and"Tengfan"(疼烦)in Treatise on Febrile Diseases and Synopsis of the Golden Chamber.[Methods]By reviewing the annotations and commentaries from different scholars throughout history,the paper summarizes and analyzes their different viewpoints.Additionally,through philological research and references to medical and non-medical literature from the Qin and Han Dynasties,the paper seeks to ascertain the semantic meaning of the word"Fan"(烦).Furthermore,by analyzing ZHANG Zhongjing's original text,the paper explores the intended meanings of these two symptoms.[Results]Scholars throughout history have interpreted these two symptoms as intense pain,pain accompanied by restlessness and inappropriate pain caused by heat.In addition to expressing the uncomfortable feeling of mind,"fan"(烦)also means numerous and frequent.In ZHANG Zhongjing's original texts,these two symptoms are used in conjunction with specific body parts,in dampness disease,malaria and Shaoyang disease,etc.,indicating frequent and recurring pain.[Conclusion]In ZHANG Zhongjing's original texts,"Fanteng"(烦疼)and"Tengfan"(疼烦)actually refer to the concept of"frequent pain".

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Epstein-Barr virus (EBV) associated post-transplant lymphoproliferative disorders (PTLD) are one of the most severe complications after hematopoietic stem cell transplantation (HSCT). This study includes 31 cases of aplastic anemia (AA) patients who developed PTLD after haploidentical transplantation, summarizing their clinical characteristics and categorizing them into either rituximab monotherapy group or combination therapy group based on whether their condition improved by 1 log after a single dose of rituximab. The incidence of PTLD after HSCT in children with AA was 10.16%, and the incidence of PTLD in patients with age >10 years was significantly increased ( χ2=11.336, P=0.010). Of the 31 patients, 27 were clinically diagnosed and 4 were pathologically confirmed. Finally, 15 patients were classified into the rituximab treatment group and 15 patients into the combination treatment groups. Finally three patients died, and the 2-year overall survival rate was (89.7±5.6) %. Standard pre-treatment protocols and EBV reactivation are risk factors affecting the prognosis of PTLD. There was no statistically significant difference in the impact of the two treatment schemes on prognosis.

Objective:To study the clinical characteristics and risk factors of necrotizing enterocolitis (NEC) in one of the premature twins.Methods:A retrospective study was conducted on twin premature infants who were admitted to the Department of Neonatology at the Third Affiliated Hospital of Zhengzhou University from January 2017 to December 2022 and only one got NEC. The twins were divided into NEC group and control group, the clinical data were collected and analyzed by SPSS 26.0 statistical software.Results:This study enrolled 109 pairs of premature twins, 109 cases in the NEC group, and 109 cases in the control group. Univariate analysis showed that birth weight, pre NEC white blood cell count were lower in NEC group than those in the control group, while the proportion of smaller than gestational age (SGA), donor of twin-to-twin transfusion syndrome, feeding intolerance, incomplete enteral feeding, start feeding time >48 h, red blood cell transfusion 72 h before NEC onset and the neutrophils ratio were higher in the NEC group than that of the control group, the difference was statistically significant ( P<0.05). Multivariate logistic analysis showed that low birth weight ( OR=1.558, 95% CI1.197-2.142), SGA ( OR=1.721, 95% CI 1.217-2.536), feeding intolerance ( OR=3.798, 95% CI 1.347-10.706), and incomplete enteral feeding ( OR=4.319, 95% CI 1.673-11.149) were independent risk factors for NEC ( P<0.05). Conclusions:Low birth weight, small for gestational age, feeding intolerance, and incomplete enteral feeding are independent risk factors for NEC in one of the premature twins.

Purpose To explore the value of texture analysis in the diagnosis and course evaluation of Parkinson's disease(PD)by analyzing the texture features of gray matter nuclei and white matter on quantitative susceptibility mapping(QSM)sequences.Materials and Methods A total of 30 PD patients and 22 normal controls from July 2019 to November 2020 in Jiangyin People's Hospital were prospectively enrolled to perform enhanced gradient echo T2* weighted angiography(ESWAN)sequence scanning.All QSM images were obtained through post-processing.Region of interest was manually obtained,including bilateral caudate heads,globus pallidus,putamen,substantia nigra,red nucleus,cerebellar dentate nucleus and white matter at the center of the semicircle.The texture features of the region of interest were extracted.After dimension reduction and screening,a set of optimal texture parameters were obtained,and a random forest prediction model was constructed.The diagnostic efficiency of the model was analyzed and evaluated and the reliability of the model was evaluated.The correlation between the selected texture features and the clinical scale of PD patients was analyzed.Results A group(n=5)of the best texture feature parameters were obtained from QSM map.The area under curve range of independent prediction PD was 0.697-0.823,the area under curve of random forest model was 0.910,and the accuracy of cross validation was 0.888.Texture feature(r4_wavelet_LLL_firstorder_Energy)of PD group was negatively correlated with the scores of the mini mental state examination(r=-0.470,P=0.011).Conclusion The texture analysis based on QSM has a high diagnostic value for PD,and the texture features of the left putamen have a certain correlation with the cognitive function of PD patients.

Objective:To explore high-risk sexual behaviors of HIV/AIDS and related factors in young students in Guangzhou.Methods:A cross-sectional survey was conducted in 5 different types of Guangzhou colleges by convenience sampling with minimum number of classes per grade and 600 samples per school from September to November 2021. The R 4.2.2 software was used to consolidate databases. Simultaneously, a logistic regression model and a decision tree algorithm model, stratifying by whether sexual behaviors had occurred before, were constructed. In each layer, the prediction performance of the two models was evaluated through area under receiver operating characteristic and the confusion matrix, and then the model with high prediction performance was retained.Results:A total of 7 346 students were surveyed. The proportion of the respondents reporting sexual experience were 9.08% (667/7 346), in whom 26.24% (175/667) had risky sexual activity in the past year. The decision tree algorithm model performs well in predicting whether high-risk sexual behaviors have occurred in the past year. When the complexity parameter value is 0.018, and nsplit reaches 4, which means there are 5 leaf nodes in the model, the cross error of the tree will be the smallest. The first best grouping variable in the decision tree was whether to use condoms throughout the first sexual behavior. If condoms were used at their sexual debut, but homosexual practices have occurred in the past year, the probability of risky sexual behavior will increase. If homosexual practices have not occurred in the past year, but the age of sexual debut was below 18 years old while the period of HIV education was after high school, the probability of risk sexual behavior will also increase.Conclusions:AIDS-related risky behaviors of young students still deserved attention. The experience of sexual debut and whether AIDS-related health education has been received before the sexual debut were significant predictors for the occurrence of high-risk sexual behavior. The decision tree algorithm model has particular applicability for predicting and screening potential risk populations.

Objective:To analyze the detection of colorectal advanced neoplasms in the population who underwent colonoscopy screening in Henan Province as part of the Urban China Cancer Screening Program and its influencing factors.Methods:A cross-sectional study design was employed. Based on the Cancer Screening Program conducted in Henan Province, the study enrolled 7 454 urban residents who manifested no symptoms and were recruited from eight cities in the province, including Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Xinxiang, and Puyang from October 2013 to October 2019, and participated in colonoscopy screening. The χ 2 test was used to compare the detection rates of colorectal advanced neoplasms among participants with different characteristics, and a multivariate logistic stepwise regression model was used to analyze the factors affecting the detection rates. Results:A total of 7 454 subjects underwent colonoscopy screening, and 112 cases of colorectal advanced neoplasms were detected. Multivariate logistic regression analysis suggested that older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative were risk factors for colorectal advanced neoplasms. The detection rate was significantly higher in people aged 60-74 years compared with those aged 40-49 years, with an odds ratio ( OR) of 2.04 (95% CI: 1.23-3.38).The rates were higher in people who smoked than those who did not smoke, with an OR of 2.21 (95% CI: 1.48-3.31), and in people who consumed more meat than those who consumed less, with an OR of 1.53 (95% CI: 1.04-2.26). Those with diabetes had a higher detection rate compared with those without, with an OR of 1.69 (95% CI: 1.07-2.69), and those with a first-degree family history of colorectal cancer had a higher detection rate than those without, with an OR of 1.64 (95% CI: 1.09-2.46). Conclusion:The detection rate of colorectal advanced neoplasms through colonoscopy screening in Henan Province covered by the Urban China Cancer Screening Program is 1.50%. Older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative are identified as risk factors for colorectal advanced neoplasms.

Objective:To analyze the 5-year relative survival rate of cancer in Henan province based on cancer registration data.Methods:Cancer survival data were extracted from the cancer registration database of Henan province with the diagnosis date between January 1, 2010 and December 31, 2019 were included. The closing date of follow-up was set as December 31, 2019. The 5-year relative survival rate of cancer was calculated using the period survival analysis method and the Ederer II method in the R package "periodR", and the interest period was between 2015 and 2019.Results:During the period of 2015-2019, the overall 5-year relative survival rate of cancer patients in Henan province was 43.6%, and after age-standardization, it was 40.2%. The overall 5-year relative survival rate showed the characteristics of higher survival rate in females than males (45.9% vs 34.7%, Z=39.60, P＜0.001) and higher survival rate in urban areas than rural areas (44.9% vs 39.1%, Z=12.97, P＜0.001). The 5-year relative survival rate for cancer patients among children aged 0-14 was 60.2%, and for adults aged 15 and above, it was 43.5%, which was standardized to 40.2% after age adjustment. There are two types of cancers with a standardized 5-year relative survival rate exceeding 70% (thyroid cancer at 82.2% and breast cancer at 71.6%), and four cancers with a rate below 30% (pancreatic cancer at 18.2%, liver cancer at 19.6%, lung cancer at 24.0%, and gallbladder cancer at 26.6%). Conclusion:The cancer 5-year survival rate in Henan Province is lower than that of the national average, indicating the need for continued enhancement of cancer prevention and control measures.
