Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To describe the epidemiological characteristics and trends of leukemia incidence in Qidong between 1972 and 2021, and provide guidelines for prevention and control measures and strategies.Methods:The cancer registry data was collected and analyzed on leukemia incidence during 1972—2021 in Qidong by sex, age and time. Crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), and average annual change percentage (AAPC) was calculated by Joinpoint software. Age-period-cohort (APC) model was used to analyze the influence of age, period and birth cohort on the changes in the incidence trend of leukemia patients.Results:From 1972 to 2021, there were 2 948 patients with leukemia in Qidong, accounting for 2.00% of all cancer new cases, CR of leukemia was 5.26/10 5, ASRC was 4.34/10 5, ASRW was 4.35/10 5. The truncated incidence of 35—64 years old was 5.29/10 5, the cumulative incidence rate between the ages of 0 and 74 years old was 0.40%, the cumulative risk was 0.40%. There were 1 608 male patients, the CR, ASRC, and the ASRW were 5.81/10 5, 4.88/10 5 and 4.85/10 5. The number of female patients were 1 340, and the CR, ASRC, and the ASRW were 4.71/10 5, 3.86/10 5 and 3.91/10 5, respectively. Temporal trends indicated significant upward trends in ASRC among both gender, males and females with AAPC values of 1.41% ( P＜0.001), 1.15% ( P＜0.001), and 1.73% ( P＜0.001), respectively. The results of the APC model showed that the average net drift value of leukemia incidence in all age groups was 1.57% (95% CI, 1.24%-1.89%), and the highest value of local drift was 3.20% (95% CI, 1.63%-4.78%) in the 80~ years old group. The incidence of leukemia increased with age. With the passage of time, the risk of leukemia incidence increased gradually compared with the rate ratio of leukemia incidence (risk ratio [ RR], 1.00) in 1992—1996, the RR of leukemia incidence increased from 0.70 during 1972—1976 to 1.57 during 2017—2021. The later the cohort was born, the greater the risk of leukemia incidence compared with the relative risk of leukemia incidence ( RR, 1.00) in 1952—1956 cohort, the RR of leukemia incidence increased from 0.24 in the 1892—1896 cohort to 2.73 in the 2017—2021 cohort. Conclusions:The incidence of the leukemia has presented a rising trend in the past fifty years. Leukemia incidence increased with age, and the period and cohort effects on the risk of incidence increase. Further research is needed to investigate the risk factors related to leukemia.

Objectives:To investigate the early related factors for hepatic insufficiency after hemihepatectomy and to construct and validate a nomogram model.Methods:This is a retrospective cohort study.There were 207 patients with liver tumor who underwent hemihepatectomy in the Department of Hepatobiliary Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2022. Using the random number method, patients were randomly divided into a model group( n=166) and a validation group( n=41) according to an 4∶1 ratio. There were 118 males and 48 females in the modeling group,with an age ( M(IQR)) of 59.0(13.3) years (range: 22.0 to 81.0 years),42 patients in the group with postoperative liver insufficiency and 124 patients in the group without postoperative liver insufficiency. There were 32 males and 9 females in the validation group, with an age of 54.0(19.0) years (range: 25.0 to 81.0 years). The first results of the peripheral blood test of patients within 24 hours after surgery were collected,and the independent related factors for incomplete postoperative liver function were determined by multivariate Logistic regression analysis,and related factors of postoperative incomplete liver function were screened by best subset selection. A nomogram model of the related factors of postoperative hepatic insufficiency after hemihepatectomy was constructed using R software,validated by internal and external validation of the model. Results:Multivariate logistic regression analysis showed that elevated D-dimer level and decreased antithrombin Ⅲ (AT-Ⅲ) activity within 24 hours after surgery were independent related factors for the development of postoperative hepatic insufficiency in hemihepatectomized patients. The results of the best subset selection showed that ALT, D-dimer, and AT-Ⅲ activity levels within 24 hours postoperatively were the most relevant factors for postoperative hepatic insufficiency. The R software was applied to build a nomogram prediction model based on the above three indicators in the model set, and the receiver operating characteristic(ROC) curve of the model showed an area under the curve of 0.803 and the calibration curve showed a U-index of -0.012 for the model( P=0.977). The results of the clinical decision analysis and the clinical impact curve indicated that the model had good clinical utility. The internal validation results of the Bootstrap method suggested that the model had reasonable consistency. The area under the ROC curve of the validation group model was 0.806, suggesting that the model had a good generalization prediction ability. Conclusions:The levels of ALT, D-dimer, and AT-Ⅲ activity within 24 hours after hemihepatectomy are valuable indicators for predicting liver insufficiency after hemihepatectomy. The nomogram model is reliable and can be used as an indicator for close postoperative monitoring.

The successful operation of the complete digital pathology(CDP) in foreign countries indicates that the full digital pathology process has entered the full implementation stage. Digital pathology in China started late and progressed slowly, so far there has not been a truly meaningful CDP. The pathologist′s understanding of digital pathology is not comprehensive enough, and there are still doubts about the time efficiency and cost effectiveness of digital pathology processes. Therefore,a comprehensive analysis of the process, overall advantages and cost-effectiveness of CDP was made by drawing on international successful experience and hands-on practice experience, in order to promote the construction and development of the CDP in our country.

Objective:To investigate the influences of sufentanil(Suf)on the inflammatory response and chondrocyte apopto-sis in rats with osteoarthritis(OA)by modulating Ras/Raf/mitogen-activated protein kinase kinase(MEK)/extracellular signal-regulated kinase(ERK)signaling pathway.Methods:SD rats were grouped into normal control group(NC group),blank control group(Blank group),low-dose Suf group(Suf-L group,1 μg/kg),high-dose Suf group(Suf-H group,5 μg/kg),Diacerein group(DC group,54 mg/kg),and Suf-H+ML-099(Ras/Raf/MEK/ERK pathway activator)group(5 μg/kg Suf+11.7 mg/kg ML-099),with 12 rats in each group.Except for the NC group,the other groups were all constructed OA rat models by transection of the medial meniscus tibial ligament of the right knee joint.After the modeling was successful,the corresponding drug treatment was carried out,and the rats in the NC group and the Blank group were intraperitoneally injected and gavaged with the same amount of normal saline,administer once a day for 3 weeks.Twenty-four hours after the last administration,the changes of tenderness threshold and thermal pain threshold of rats were monitored;serum levels of TNF-α,IL-1β and IL-6 were detected by ELISA;Safranin O-Fast green staining was used to detect the pathological changes of cartilage tissue;TUNEL staining was used to detect chondrocyte apoptosis;Western blot was used to detect the expressions of Ras/Raf/MEK/ERK signaling pathway protein and matrix metalloproteinase 13(MMP-13)protein in carti-lage tissue.Results:Compared with NC group,the tenderness threshold and heat pain threshold of rats in Blank group were decreased(P<0.05),and the pathological injury of cartilage tissue was serious,TNF-α,IL-1β,IL-6 levels,Mankin score,chondrocyte apopto-sis rate,Ras,Raf,MEK,p-ERK1/2,MMP-13 protein expressions were increased(P<0.05);compared with the Blank group,the change trends of the corresponding indicators in Suf-L group,Suf-H group and DC group were opposite to the above(P<0.05);ML-099 attenuated the effect of high dose Suf on OA rats.Conclusion:Suf may attenuate the inflammatory response and chondrocyte apoptosis in OA rats by inhibiting the Ras/Raf/MEK/ERK signaling pathway.

Neoadjuvant chemoradiotherapy (NCRT) is the standard therapeutic strategy for locally advanced rectal cancer (LARC). Due to the different responses of patients to NCRT, the clinical prognosis of patients varies greatly. Therefore, it is important to establish sensitive biomarkers to predict the response of patients to treatments before NCRT. Immune cells in the tumor microenvironment (TME) were closely related to the efficacy of NCRT in patients with LARC. This paper reviewed the research progress on the relationships of cytotoxic T cells, programmed death-ligand 1 (PD-L1), tumor-associated macrophages (TAMs), regulatory T cells (Treg) and neutrophil to lymphocyte ratio (NLR) with chemoradiotherapy sensitivity in rectal cancer, illustrated the potential and limitations of these immune cells in predicting chemoradiotherapy response in rectal cancer, and provided a feasible direction for future researches.

Objective:To investigate the effects of acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation on quality of life in patients with stable chronic obstructive pulmonary disease (COPD).Methods:A total of 109 patients with stable COPD admitted to People's Hospital of Gaomi from March 2019 to May 2020 were included in this study. They were randomly divided into a control group ( n = 54) and an observation group ( n = 55). Both groups were given tiotropium bromide powder inhalation and acupoint application therapy ( Dazhui, Shenque, Feishu, Pishu, Shenshu and Zusanli). Chinese medicine ointment was applied in the observation group, but not in the control group. All patients were treated for 6 consecutive months. Before and after treatment, pulmonary function indicators [forced expiratory volume in the first second (FEV 1), the percentage of expiratory volume in the first second (FEV 1%), forced vital capacity (FVC), FEV 1/FVC], modified Medical Research Council (mMRC) dyspnea scale score, and the Saint George's Respiratory Questionnaire (SGRQ) score were compared between the two groups before and after treatment to evaluate therapeutic efficacy and quality of life. Results:Before and after treatment, there were no significant differences in FEV 1, FEV 1% and FEV 1/FVC between the two groups (all P > 0.05). After treatment, mMRC score and SGRQ total score in the observation group were (1.91 ± 0.27) points and (38.54 ± 8.18) points, respectively, which were significantly lower than (2.43 ± 0.33) points and (43.12 ± 7.86) points in the control group ( t = 4.93, 4.47, both P < 0.05). The number of exacerbations and the number of hospitalizations were (0.42 ± 0.09) times/6 months and (0.27 ± 0.05) times/6 months in the observation group and they were (0.69 ± 0.17) times/6 months and (0.47 ± 0.13) times/6 months in the control group. There were significant differences in these indices between the two groups ( t = 3.90, 3.85, P < 0.05). Conclusion:Acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation has a good therapeutic effect on stable COPD. The combined therapy can reduce the number of acute attacks and improve patient's quality of life. This study is scientific and innovative.
