This is to report the screening, extracting and validating antitumor components and compounds from Stellera chamaejasme L. under the case of discrete distribution of active data. In this work, different components from Stellera chamaejasme L. were collected by HPD macroporous resin and polyamide resin column, and their antitumor activity on A549 were tested by MTT assay. Activity results indicate that activity of components at 30-39 min is more potent than that of Stellera chamaejasme L. extract, and the activity of components at 33.97 min is equivalent to positive drug, cis-platinum at 100 microg x mL(-1), but with totally different mode of action. Under the case of discrete activity, the weight analysis is capable of screening active components and compounds from natural products.

Objective:To compare the therapeutic outcomes between use of antibiotic cement versus non-use of antibiotic cement in the treatment of tibial osteomyelitis after radical debridement.Methods:A retrospective analysis was made of the 68 patients with local tibial osteomyelitis of Cierny-Mader Type Ⅳ who had been treated at Department of Orthopaedic Trauma, The Second People’s Hospital of Shenzhen from January 2010 to June 2015. The dead space was filled with antibiotic-impregnated bone cement beans after radical debridement of the infected bone in 32 of them (cement group) but was not in 36 of them (no-cement group). The operations for both groups were performed by the same surgical team who filled the bone defects after excision of infected bone using Ilizarov bone transport. The 2 groups were compared in terms of Paley functional scores of bone and limb, external fixation index (EFI), infection recurrence rate, total hospital costs and other complications.Results:The 2 groups were comparable because there was no significant difference between them in the preoperative general data ( P>0.05). The cement group was followed up for (71.2±8.9) months and the no-cement group for (71.6±9.7) months, showing no significant difference ( P>0.05). By the Paley functional scores, the good to excellent rate for bone was 100% for both groups (32/32 versus 36/36) while the good to excellent rate for limb was 93.8% (30/32) for the cement group and 94.4% (34/36) for the no-cement group, showing no significant differences between them ( P>0.05). The EFI was (49.0±10.5) d/cm for the cement group and (49.5±11.4) d/cm for the no-cement group, showing no significant differences between them ( P>0.05). The infection recurrence rate at the final follow-up was 3.12% (1/32) for the cement group and 2.78% (1/36) for the no-cement group, showing no significant differences between them ( P>0.05). The total hospital cost was (70,944.1 ± 1,135.5) Yuan RMB for the cement group and (55,205.2 ± 897.3) Yuan RMB for the no-cement group, showing a significant difference ( P<0.05). No serious complications with sequelae were found in either of the 2 groups. Conclusion:In the treatment of local tibial osteomyelitis of Cierny-Mader Type Ⅳ, it is not necessary to fill the dead space with antibiotic cement when radical debridement is achieved.

Objective To discuss the clinical effect of music adjunctive therapy (MAT) on patients with persistent vegetative state (PVS) after brain injury. Methods One hundred and eighty-nine patients with PVS after brain injury, admitted to our hospital from January 2013 to January 2018, were divided into two groups: 93 patients in a control group underwent routine treatment, medication (nerve cell nutritional agents, arousal medicine, and vasodilator)+rehabilitation (massage, acupuncture, physiotherapy and hyperbaric oxygen therapy); 96 patients in a treatment group were treated by routine treatment plus MAT for 6 months. Abnormal rate of middle latency auditory evoked potential (ML-AEP) and clinical effects were compared between the two groups one, two, 4 and 6 months after treatment. Results (1) The abnormal rate of ML-AEP 4 and 6 months after treatment was significantly decreased as compared with that before treatment in both two groups (P<0.05); the abnormal rate of ML-AEP in control group 4 and 6 months after treatment (77.42% and 65.59%) was significantly higher than that in the treatment group (55.21% and 40.63%). (2) Total effective rate in the treatment group (91.18%) was significantly higher than that in the control group (79.57%, P<0.05). Conclusion MAT can promote the recovery of consciousness and neurological function in PVS patients after brain injury, and it is simple in operation, which is worthy of further clinical application.

Objective:To explore the effects and feasibility of group reminiscence therapy on improving the negative emotions of the elderly inpension sectors.Methods:From April to June 2019, using convenient sampling method, a total of 19 elderly people who volunteered and met the selection criteria at two pension sectors in Beijing were selected to participate in a four-week group reminiscence therapy. The scores of the negative emotions, pulse rate changes, behavior changes, and facial photo changes of each subject before and after the intervention were compared, and the relationship between the changes in the negative emotion score and the number of participations was analyzed to evaluate the intervention effect.Results:After intervention, the elderly negative emotion scale score increased and the pulse rate increased, and the difference was statistically significant compared with that before the intervention ( P<0.01) .After the intervention, 15 of the 16 subjects showed observable facial expression changes, and the expression changes after each intervention were different. According to the caregiver's feedback, compared with that before the intervention, the study subjects had different degrees of positive behavioral changes after the intervention. There was no correlation between the change of negative emotion score and the times of participation in the elderly ( P>0.05) . Conclusions:Group reminiscence therapy can significantly improve the negative emotions of elderly people in nursing homes, and has a positive effect on emotional mobilization, which can be used as a normalizing intervention for elderly people to intervene in mental health in nursing homes.

Objective:To summarize the clinical characteristics of patients with epilepsy caused by focal cortical dysplasia (FCD), and identify the influencing factors for postoperative seizure controls.Methods:Fifty-seven patients with epilepsy caused by FCD admitted to Department of Neurosurgery, Third Affiliated Hospital of Zhengzhou University from July 2019 to November 2023 were chosen; standard preoperative evaluation, surgery, postoperative management and follow-up were performed. A retrospective study of clinical data, imaging and video electroencephalogram (VEEG) data, surgical approaches, pathological findings, and follow-up data was performed; influencing factors for postoperative seizure controls were analyzed.Results:In these 57 patients with epilepsy caused by FCD, 29 were males (50.88%) and 28 were females (49.12%). Onset age was 30.00 (8.00, 74.50) months, and surgery age was 95.00 (50.00, 138.50) months. Focal to bilateral tonic-clonic seizures (42/57; 73.68%) and epileptic spasms (13/57; 22.81%) were common seizure types. Cranial MRI was positive in 34 patients (59.65%), mainly manifested as abnormal cortical gyri/sulci morphology (17/57; 29.82%). In 43 patients accepted PET-CT, hypometabolic sites were detected in 40 (93.02%), and complete agreement between PET/MRI fusion results and actual lesion sites was noted in 40 (93.02%). FCD type I was noted in 16 patients (28.07%), type II in 39 (68.42%), and type III in 2 (3.51%). By December 2023, 44 (77.19%) had Engel grading I, 4 (7.02%) had grading II, 4 (7.02%) had grading III, and 5 (8.77%) had grading IV. Children with good prognosis (Engel grading I+II) and those with poor prognosis (Engel grading III+IV) showed significant differences in terms of time from first seizure to surgery, positive/negative MRI, and regularity of postoperative ASMs ( P<0.05). Conclusions:Focal to bilateral tonic-clonic seizure is the most common seizure type in patients with epilepsy caused by FCD, and abnormal cortical gyri/sulci morphology is the most common MRI manifestation; PET/MRI fusion imaging is superior to PET-CT or MRI in identifying epileptogenic foci. Poor seizure control can be noted in patients with long onset time to surgery, with negative cranial MRI results, or with irregular postoperative ASMs.

With completing a baseline survey of a large natural population cohort, conducting regular follow-up has become a key factor in further improving the quality of cohort construction and ensuring its sustainable development. Typical cohort follow-up methods include repeat surveys, routine monitoring, and community-oriented surveillance. However, in practical applications, there are often issues such as high costs, difficulty, and high error rates. Telephone follow-up is an important supplementary method to the methods mentioned above, as it has the characteristics of low cost, fast response, and high quality. However, the with difficult organization, quality control is challenging, response rates are low, and management levels vary widely, which limits its widespread use in large-scale population cohort studies. Given the above problems, this study draws on customer relationship management based on the actual needs of the China Northwest Cohort follow-up. It relies on the REDCap electronic data collection platform to build a telephone follow-up management and quality control system. Targeted solutions are provided for key issues in telephone follow-up implementation, including organizational structure, project management, data collection, and process quality control, to improve the quality control level of telephone follow-up comprehensively and thereby enhance the quality and efficiency of follow-up. We hope to provide standardized follow-up programs and efficient quality control tools for newly established and existing cohort studies.

The diagnosis and treatment resources for rare diseases in China are highly imbalanced. The basic diagnosis and treatment capabilities are weak, the diagnosis period for patients is long, and the rates of missed diagnosis and misdiagnosis are relatively high. The establishment of a hierarchical diagnosis and treatment system is the inevitable approach to enhancing the diagnosis and treatment standards of rare diseases. Currently, the implementation of the domestic hierarchical diagnosis and treatment system for rare diseases still confronts numerous challenges, such as ambiguous referral standards and processes of primary medical institutions, and ineffective information interaction among institutions at all levels. Thus, it is essential to facilitate high-level information construction for the hierarchical diagnosis and treatment of rare diseases. This paper explores the process of constructing a multidisciplinary joint remote diagnosis and treatment platform and a health management platform through informatization, with the hope of establishing two closed loops of digital diagnosis and treatment services and health follow-up management for patients with rare diseases, as well as achieving timely diagnosis and lifelong health management for patients. It integrates and optimizes auxiliary diagnostic tools, promotes the rapid dissemination of rare disease diagnosis and treatment experiences to the grassroots, enhances the information construction level of the hierarchical diagnosis and treatment system, and endeavors to address the practical predicament of weak diagnosis and treatment capabilities of rare diseases in grassroots medical institutions. Additionally, this paper proposes an essential approach for multi-dimensional independent innovation to guide the popularization of efficient and high-quality rare disease diagnosis and treatment services. By encompassing innovating the rare disease diagnosis and treatment collaboration network and multidisciplinary diagnosis and treatment model, facilitating the application of the latest biomedical and informatics technologies to the grassroots, and constructing a national intelligent data platform for rare disease innovation, a new model for rare disease services with Chinese characteristics will be established. This will significantly enhance the medical treatment level of rare diseases in China and strive for more benefits for patients.
