BACKGROUND: In China, stroke burden remains severe as it is a major cause of mortality and disability. Detailed analyses across different subtypes will help optimize intervention strategies, enhance resource allocation efficiency, and ultimately reduce the overall disease burden. METHODS: We conducted a descriptive analysis of the incidence, prevalence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) of stroke and its subtypes using data (1990-2021) from the Global Burden of Disease (GBD) database. A Joinpoint regression model was applied to quantitatively analyze the indicators and calculate the annual percentage change (APC) and average annual percentage change (AAPC). We applied the Bayesian age-period-cohort (BAPC) model to project trends for 2022-2040. RESULTS: Incidence of stroke increased by 100.64% from 1990 to 2021, with ischemic stroke (IS) exhibiting the largest increase (201.13%) among all the subtypes, and the incidence being consistently higher in males than in females. The YLL/YLD ratio for stroke and its subtypes has decreased, with the YLL/YLD ratio falling from 20.13 to 9.48 in 1990-2021, indicating an increase in non-fatal burden. After adjusting for age, the age-standardized incidence rates (ASIRs) of stroke and its subtypes declined, except for IS. The age-standardized mortality rate (ASMR) for subarachnoid hemorrhage (SAH) decreased significantly (APC: -15.31%; 2000-2004), with the largest reduction in the age-standardized DALY rate (ASDR) also occurring during this period (APC: -14.22%). Furthermore, BAPC projections (2022-2040) indicate that stroke ASIRs in males will slightly decline but increase in females. Meanwhile, the ASIR of IS is expected to continue to rise. Overall, the ASMR and ASDR are projected to decline. CONCLUSIONS Although China has made some progress in stroke prevention and control, several challenges remain. Controlling IS must be prioritized, especially due to the high stroke burden among males.

Objective:To construct the symptom network of patients after hepatectomy, analyze the core symptoms and bridge symptoms in the network, and provide evidence for symptom management of patients after hepatectomy.Methods:A cross-sectional study was conducted to select the patients after hepatectomy in the Second Affiliated Hospital of Zhejiang University from January to July 2024 by convenient sampling method. M.D. Anderson Sympotom Inventory and the Symptom Module Specific to Primary Liver Cancer were used to investigate the composition of symptoms. Symptom clusters were extracted by exploratory factor analysis, and simultaneous network layout was constructed by R language to describe the relationship between symptoms and analyze the central indicators.Results:A total of 228 questionnaires were distributed and 220 valid questionnaires were collected. There were 174 males and 46 females, aged (60.31 ± 10.69) years old. The four symptom groups were neuroaffective symptom group, gastrointestinal symptom group, fatigue-related symptom group and pain-related symptom group, and the cumulative variance contribution rate was 54.592%.In the concurrent symptom network analysis, distress was the core symptom of node centrality index, and the top 3 bridge symptoms were pain (r bs=2.40), decreased appetite (r bs=2.10) and nausea (r bs=2.00), the correlation stability coefficients of network strength centrality, compact centrality and expected influence values were 0.595, 0.595 and 0.673, the symptom group network was stable. Conclusions:Distress is the core symptom of patients after hepatectomy, and pain, decreased appetite and nausea are bridge symptoms. It is recommended that medical staff construct intervention programs based on core symptoms and bridge symptoms, implement precise symptom management, and improve the outcome of symptom management of patients.

With the changing disease spectrum, the incidence of tumors is increasing and tends to occur among the youth. The long-term survival rate of patients with cancer has increased significantly, and attention to their reproductive rights is growing. Surgery, chemotherapy, radiotherapy, immunotherapy, and molecular targeted therapy are the conventional treatment methods for cancer, with each exerting different effects on the fertility of patients. Common fertility preservation techniques currently include sperm cryopreservation, embryo and oocyte cryopreservation, ovarian tissue cryopreservation, uterine transplantation, and assisted reproductive technology. This article systematically summarizes the influence of different antitumor treatments on fertility, as well as the current status and prospects of fertility preservation in patients with cancer. This study aims to improve cooperation between clinical oncologists and reproductive medicine doctors to enhance fertility preservation for patients with cancer.

Objective:To evaluate the classification of petroclival meningiomas(PCM), proposed selection of microsurgical approach and therapeutic outcomes.Methods:Retrospectively analyzed clinical data of 179 cases of PCM from Department of Neurosurgery, Xiangya Hospital, Central South University between January 2011 and November 2020. There were 28 males and 151 females with an age of(49.9±10.2) years(range: 22 to 75 years) and the tumor size of(44.8±10.3)mm(range: 15 to 80 mm). The mean duration of symptom ( M( Q R)) was 18.0(40.6)months(range:1 week to 320 months) and the mean preoperative Karnofsky performance scale(KPS) was 78.6±13.3(range: 40 to 100). The PCM were classified into 5 types according to the difference in the origin of dural attachment, involvement of adjacent structures and growth patterns through preoperative MRI. The surgical approaches were selected based on the proposed classification, and the clinical characteristics, surgical record, and follow-up data of each type were reviewed. Results:The PCM were divided into clivus type(CV, 4 cases), petroclival type(PC, 60 cases), petroclivosphenoidal type(PC-S, 62 cases), sphenopetroclival type with 2 subtypes(S-PC, 50 cases) and central skull base type(CSB, 3 cases). All of 176 cases were obtained microsurgical treatment except CSB type. The gross total resection reached in 124 cases(70.5%) with 112 cases of retrosigmoid approach(RSA), 27 cases of subtemporal transtentorial transpetrosal approach, 13 cases of pretemporal trancavernous anterior transpetrosal approach(PTCA), 12 cases of extended pterional transtentorial approach(EPTA) and presigmoid combined supra-infratentorial approach, respectively. The RSA could be adopted in both of CV type and PC type and most of PC-S type(71.0%). S-PC subtype Ⅰ and subtype Ⅱ were mainly underwent EPTA(40.8%) and PTCA(52.2%), respectively. Seventy-two cases(40.9%) gained new neurological dysfunctions mainly with the cranial nerve paralysis. The postoperative morbidity and complications were recovered or improved with conservative and positive symptomatic and supportive treatment. There was no intraoperative and postoperative death case. One hundred and sixty four cases(93.2%) of operative patients were followed with the duration of 24(48)months(range:3 to 108 months). Tumor recurrence and progress were identified in 14 cases(10.4%) and 14 cases(28.6%), respectively. Compared with postoperative neurological status, 89 patients(54.3%) had improved and 38 patients(23.2%) were still suffering various degrees of neurological dysfunctions during the follow-up. The recent KPS was 84.2±11.4(range: 50 to 100) without statistical difference from preoperative KPS ( t=-1.356, P=0.125). As for each type, there were statistically significant differences in brain stem edema (χ 2=3.482, P=0.038), gross total resection (χ 2=9.127, P=0.001), surgical duration( F=8.954, P=0.013), postoperative length of stay( F=3.652, P=0.025), postoperative complications (χ 2=1.550, P=0.024), postoperative KPS( F=2.856, P=0.042) and tumor recurrence/progress (χ 2=4.824, P=0.013). Conclusion:The precise and comprehensive classification of PCM and specific individual treatment strategy are benefit to evaluate the diverse clinical prognosis, choose optimal surgical approaches, elevate gross total resection, diminish neurological dysfunctions and restraint tumor recurrence, so as to improve the quality of life for patients.

Objective    By applying the mutual corroboration in the diagnosis, we aimed to improve the accuracy of preoperative imaging diagnosis, select the appropriate timing of operation and guide the follow-up time for patients with pulmonary nodules. Methods    Clinical data of 1 368 patients with pulmonary nodules undergoing surgical treatment in our department from July 2016 to October 2019 were summarized. There were 531 males and 837 females at age of 44 (21-67) years. The intraoperative findings, images and pathology were classified and analyzed. The imaging pathology and pathological changes of pulmonary nodules were shown as a dynamic process through mutual collaboration and interaction. Results    Of 1 368 patients with pulmonary nodules, 376 (27.5%) were pure ground-glass nodules, 729 (53.3%) were mixed ground-glass nodules and 263 (19.2%) were solid nodules. Among the pure ground-glass nodules, adenocarcinoma in situ (AIS) accounted for the highest proportion (156 patients), followed by microinvasive adenocarcinoma (MIA, 90 patients), atypical adenomatous hyperplasia (AAH, 85 patients), and benign tumors (20 patients). Among mixed ground-glass nodules, 495 patients were invasive adenocarcinoma (IA) and 207 patients of MIA. no patient was featured by AAH, AIS or MIA. Conclusion    The mutual collaboration and interaction can improve the accuracy of preoperative diagnosis of pulmonary nodules, and it supports the choice of operation timing and the judgment of follow-up time.

The subarachnoid hemorrhage (SAH) caused by ruptured intracranial aneurysms (IAs) is always a lethality. Increasing evidence suggests a familiar aggregation of IA occurrence, which may relate to genetics and there might be an increasing number of IAs in IA families when mutation of disease genes is aggregating. With the progress in the study of familiar intracranial aneurysms (FIAs), a large number of chromosome fragments are found to be related with IAs, such as 1p36, 5q31, 7q11, 14q22, 17cen, 19q13, Xp22. Further studies indicated that mutation of several genes could be the cause of FIAs, including TNFRSF13B, ANRIL, SOX17, ADAMTS15, RNF213 and LOXL2. The independent genetic epidemiologic study on aneurysm families can be used to discover the related genes more effectively, and to explore the mechanism of occurrence of IAs. It's also the precondition for the prevention of disease.
