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 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.
