OBJECTIVE: To approach efficacy of Dianning tablet in the treatment of refractoriness epilepsy.METHODS: 180 patients with refractoriness epilepsy were randomized into treatment group,control group Ⅰand control group Ⅱ(n=60).Treatment group were given Dianning tablet produced by our hospital.Control group Ⅰwere treated with carbamazepine tablet and clonazepam tablet while control group Ⅱ were treated with valproate sodium tablet and clonazepam tablet.The efficacies of three groups were compared after 6 months.RESULTS: Treatment group was better than control groups in total effective rate,seizure frequency and improvement of EEG (P

Objective:To observe the presence or absence of necroptosis in PC12 cells after radiation injury, and to detect the expression of receptor-interacting protein 3(RIP3) and evaluate its regulatory effect on necroptosis.Methods:PC12 cells were treated with different doses of irradiation and their necroptosis was detected by lactate dehydrogenase (LDH) release at different time points. After pretreatment with necroptosis inhibitor Necrostatin-1(Nec-1), the changes of cell necroptosis were detected by LDH. The expression level of RIP3 after irradiation intervention was detected by Western blot (WB). After pretreatment with the RIP3-specific inhibitor GSK′872, the changes of cell necroptosis were detected by LDH. The best transfection sequence of RIP3 knockout was screened by WB. The cells were divided into the control group, irradiation group, solvent control group, no-load control group and pretreatment group. WB, immunofluorescence staining, MTT, LDH and Annex V-fluorescein Isothiocyanate/Propidium Iodide (AnnexV-FITC/PI) flow cytometry were used for detection and analysis.Results:After 4 Gy irradiation, the degree of cell necrosis was the highest after 3 hours of culture, and the expression level of RIP3 protein was up-regulated. The cell necrosis was decreased after Nec-1, GSK′872 and RIP3 gene knockdown pretreatment.Conclusions:The radiation injury of 4 Gy can induce the necroptosis of PC12 cells, and the most significant effect can be observed when cultured for 3 hours after irradiation. RIP3 is involved in the process of necroptosis of PC12 cells induced by radiation injury, and plays a pivotal positive regulatory role.

OBJECTIVE To compare t he diff erences of the fingerprint and in vitro antioxidant activity between decoction pieces of Polygonum cuspidatum by integrated technology of habitat processing and processing （short for IPDP ）and traditional processing decoction pieces （short for TPDP ）. METHODS Ten batches of IPDP and ten batches of TPDP were prepared by integrated technology and traditional technology ，respectively. HPLC method was used to establish and compare the fingerprints of IPDP and TPDP. The scavenging rates of DPPH free radical ，ABTS free radical ，superoxide free radical and hydroxyl free radical and reducing activity of Fe 3+ were detected for IPDP and TPDP. In vitro antioxidant activities were compared between IPDP and TPDP. RESULTS There were 11 common peaks in the fingerprints of IPDP and TPDP ，among which 17 came from IPDP and 13 came from TPDP. The peak heights of peak 6（polydatin）and peak 15（emodin-8-O-β-D-glucoside）in IPDP were significantly higher than those in the TPDP ，and the peak heights of peak 13（resveratrol），peak 17（emodin）and peak 19（physcion）in the TPDP were significantly higher than those in the IPDP. The results of in vitro antioxidant test showed that IPDP and TPDP had a certain scavenging capacity on DPPH free radical ，ABTS free radical ，superoxide free radical and hydroxyl free radicals ，and also had a certain reducing capacity on Fe 3+. CONCLUSIONS The integrated processing technology of P. cuspidatum has a good retention effect on the glycosides in P. cuspidatum ，and the in vitro antioxidant activity of IPDP is stronger than that of TPDP.

OBJECTIVETo discuss the clinical features of perianal Crohn disease (PCD).

METHODSClinical data of 52 PCD patients who were treated at the Department of Colorectal Surgery, Affiliated Hospital of Nanjing University of Chinese Medicine from June 2011 to October 2014 were analyzed retrospectively. Montreal classification, clinical symptoms, the subtype of perianal lesions, history of perianal surgery and medical treatment, disease active indexes, serum inflammation markers and nutritional indexes were included.

RESULTSAmong 52 patients, there were 40 males and 12 females with a mean age of (27.9±9.1) years. According to Montreal classification, 51.9%(27/52) of patients had ileocolic involvement and 75.0%(39/52) had inflammatory disease behavior. Thirteen (25.0%) and 15(28.8%) patients had abdominal pain and diarrhea respectively at admission. With respect to the subtype of perianal lesions, there were 32(61.5%) cases of anal fistula and 16(30.8%) cases of perianal abscess. Thirty-nine(75.0%) and 33(63.5%) patients had a history of perianal surgery and medical treatment before admission resepectively. Laboratory findings revealed high C-reaction protein level in 63.5%(33/52), high erythrocyte sedimentation rate in 61.5%(32/52), elevated platelet in 32.7%(17/52), low body weight in 44.2%(23/52), low albumin in 26.9%(14/52) and anemia in 42.3%(22/52) of patients.

CONCLUSIONSThe clinical features of PCD patients include male predominant, early onset disease, high prevalence of ileocolic involvement and inflammation disease behavior. Features prompting underlying PCD diagnosis include characteristic gastrointestinal symptoms, requiring multiple perianal surgery, and abnormality of inflammation markers and nutritional indexes.

Although the development of COVID-19 vaccines has been a remarkable success, the heterogeneous individual antibody generation and decline over time are unknown and still hard to predict. In this study, blood samples were collected from 163 participants who next received two doses of an inactivated COVID-19 vaccine (CoronaVac®) at a 28-day interval. Using TMT-based proteomics, we identified 1,715 serum and 7,342 peripheral blood mononuclear cells (PBMCs) proteins. We proposed two sets of potential biomarkers (seven from serum, five from PBMCs) at baseline using machine learning, and predicted the individual seropositivity 57 days after vaccination (AUC = 0.87). Based on the four PBMC's potential biomarkers, we predicted the antibody persistence until 180 days after vaccination (AUC = 0.79). Our data highlighted characteristic hematological host responses, including altered lymphocyte migration regulation, neutrophil degranulation, and humoral immune response. This study proposed potential blood-derived protein biomarkers before vaccination for predicting heterogeneous antibody generation and decline after COVID-19 vaccination, shedding light on immunization mechanisms and individual booster shot planning.
