Objective To investigate the value of 18F labeled prostate-specific membrane antigen(18F-PSMA)-1007 developing agent PET/CT(18F-PSMA-1007PET/CT)examination in the diagnostic evaluation and therapeutic decision of the newly diagnosed prostate cancer(PCa)and follow up after radical prostatecto-my(RP).Methods This study adopted the retrospective observational study method.A total of 68 patients receiving 18 F-PSMA-1007 PET/CT examination in this hospital from September 2022 to October 2023 were analyzed,including 36 cases of newly diagnosed PCa and 32 cases of biochemistry follow up failure after RP.A total of 30 items of clinical data were collected,including 8 items of basic clinical characteristics,7 items of pa-thology-related characteristics and 15 items of imaging characteristics.The patients clinical characteristics in the newly diagnosed PCa and biochemical failure after RP conducted the descriptive analysis.The Fisher exact probability method was used to analyze the differentiation of the SUVmax of primary lesions in different clini-cal subgroups[different tPSA levels at diagnosis,different mi-T stages,different Gleason scores at postopera-tive pathological puncture and different pathological types]in the newly diagnosed PCa group and the differ-entiation of recurrent lesion detection rates in different clinical subgroups(different tPSA in 18F-PSMA-1007 PET/CT examination,different pathological T stages,different lymph node invasion and different pathological Gleason scores in the biochemical failure after RP group.The Spearman correlation was adopted to test and analyze the correlation between the imaging features of positive lesions and tPSA.Results In the newly diag-nosed PCa group,there were 1 case of prostatic hyperplasia and 35 cases of PCa.SUVmax had no statistical differences among the primary lesions with different tPSA levels(P=0.81),different mi-T stages(P=0.70),different puncture Glleasonscores(P=0.20)and different pathological types(P=0.71).Moreover the tPSA value at diagnosis was positively correlated with the number of metastatic lesions(r=0.410,P=0.01).The clinical treatment decisions in 11 cases(31.43％)were changed according to the examination re-sults.In 9 cases of RP combined with lymph node dissection,the accuracy rate and concordance rate of 18F-PS-MA-1007 PET/CT and MRI in the lymph node detection rate all were 100％.I n the biochemical failure after RP group,the overall recurrent lesion detection rate was 71.88％(23/32),the operative area in situ recurrence(11 cases,34.38％)and bone metastasis(11 cases,34.38％)were most common.The differences of 18F-PS-MA-1007 PET/CT recurrent lesions detection rates had no statistical differences among the patients with dif-ferent tPSA levels(P=0.08),different pathological T stages(P=0.10),different postoperative pathological lymph node invasions(P=0.68)and different pathologic Gleason score in the 18F-PSMA-1007 PET/CT ex-amination.In the 18 F-PSMA-1007 PET/CT examination in the biochemical failure after RP,the tPSA value in the recurrent lesion was positively correlated with the number of recurrent lesions(r=0.48,P=0.01),SUVmax value in the recurrent lesion(r=0.46,P=0.01)and the SUVmean value(r=0.38,P=0.03).The clinical treatment decision in 18 cases(56.25％)was changed according to the examination results.Conclusion 18 F-PSMA-1007 PET/CT has good diagnostic value and efficiency for primary lesion and metastasis lesion of new-ly diagnosed PCa and recurrent foci of biochemical failure after RP.

OBJECTIVE：To study the improvement effect and mechanism of MEBO on lipopolysaccharide （LPS）-induced injury of rat skin fibroblasts. METHODS ：Skin fibroblasts of rats were divided into control group ，LPS group （5 μg/mL）， Kangfuxin solution group （positive control ，5 μg/mL LPS+1.25％ Kangfuxin solution ）and MEBO group （5 μg/mL LPS+0.6 mg/mL MEBO），with 6 wells in each group. Inflammatory injury cell model was induced by LPS （except for control group ）. After a certain period of cultivation ，the cell survival rate and cell migration rate were detected in each group. The contents of TNF-α and IL-6 in cell supernatant was detected. The localization and fluorescence intensity of IL- 6 protein were detected. The protein expression of PTEN ，p-p65，TNF-α，IL-6，PI3K and Akt in the fibroblasts were also determined. RESULTS ：Compared with control group ，survival rate of the fibroblasts was increased significantly in LPS group ，while cell migration was decreased significantly；the contents of TNF-α and IL-6 in cell supernatant as well as relative protein expression of PTEN ，p-p65，TNF-α， IL-6 and PI 3K were increased significantly （P＜0.05 or P＜0.01）；IL-6 protein mainly expressed in the cytoplasm ，and the fluorescence intensity was enhanced. Compared with LPS group ，survival rate of the fibroblasts was decreased significantly in Kangfuxin solution group and MEBO group ，while migration rate was increased significantly ；the contents of TNF-α and IL-6， relative protein expression of PTEN ，p-p65，TNF-α，IL-6（except for Kangfuxin solution group ），PI3K and Akt （except for Kangfuxin solution group ） were decreased significantly （P＜0.05 or P＜0.01），while fluorescence intensity of IL- 6 protein decreased；relative protein expression of TNF-α，IL-6，PI3K and Akt in MEBO group were significantly lower than Kangfuxin solution group （P＜0.05 or P＜0.01）. CONCLUSIONS ：MEBO can inhibit the proliferation of LPS-induced skin fibroblasts ， reduce the level of inflammatory factors and the intensity of inflammatory reaction ， which may be related to the jiang- down-regulation of PTEN/NF-κB，PI3K/Akt signaling pathway.

Objective:To explore the effect of the care and nursing practice plan based on the timing theory in primary caregivers of infants with infantile spasms.Methods:From July 2019 to June 2020, 80 infants with infantile spasm and 80 primary caregivers in the Department of Neurology of Hunan Children's Hospital were selected as the research object. All infants with infantile spasms were numbered according to the time of admission. The odd-numbered infants were admitted to the First Department of Neurology as the observation group, and the even-numbered children were admitted to the Second Department of Neurology as the control group, with 40 infants and 40 primary caregivers in each group. The control group carried out conventional treatment and nursing, and the observation group implemented a care and nursing practice plan based on the timing theory on the basis of the control group. Before and after the intervention, the Caring Ability Inventory (CAI) , Family Caregiver Task Inventory (FCTI) , Caregiver Burden Inventory (CBI) , and Gesell Developmental Schedules (GDS) were used to evaluate the caring ability, caregiving ability, care load of the primary caregivers of the two groups of infants, and the cognition function of the two groups of infants.Results:After the intervention, the total CAI scores of the primary caregivers in the observation group were higher than those before intervention and those in the control group after the intervention, and the total scores of FCTI and CBI were lower than those before intervention and those in the control group after the intervention, and the differences were statistically significant ( P<0.05) . After the intervention, the developmental quotient (DQ) values of the five energy areas of GDS in the observation group were higher than those before the intervention, and the DQ values of the three energy areas of gross motor, fine motor, and language were higher than those of the control group after the intervention, and the differences were statistically significant ( P<0.05) . Conclusions:The care and nursing practice plan based on the timing theory can improve the caring ability and caregiving ability of the main caregivers of children with infantile spasms, reduce the care load, and improve the cognitive function of the children.

Objective: To explore the clinical features and risk factors of hepatic injury due to immune checkpoint inhibitors (CPI) therapy in malignant tumor. Methods: Data of 112 patients (64 men and 48 women) who received CPI between January 2016 and March 2019 in Chinese Academy of Medical Sciences and Peking Union Medical College Shenzhen Hospital, and Huazhong University of Science and Techology Union Shenzhen Hospital were retrospectively collected. The median age of these patients was 60 years. Results: Hepatic adverse events were observed in 30 patients out of 112 patients (26.8%). Among them, the incidence of grade 3-5 hepatic adverse events were 7.14% (8/112). The median time of hepatic adverse event occurrence was 3 weeks (2-30) after undergoing therapy. The results of univariate and multivariate analyses showed that liver cancer was attributed to the CPI induced hepatitis (P<0.05). Patients with severe hepatic injury got almost complete resolution after receiving methlprednisolone for 4 to 6 weeks. Conclusion Live cancer is the risk factor of CPI-related hepatic adverse events.

The teeth are highly differentiated chewing organs formed by the development of tooth germ tissue located in the jaw and consist of the enamel, dentin, cementum, pulp, and periodontal tissue. Moreover, the teeth have a complicated regulatory mechanism, special histologic origin, diverse structure, and important function in mastication, articulation, and aesthetics. These characteristics, to a certain extent, greatly complicate the research in tooth regeneration. Recently, new ideas for tooth and tissue regeneration have begun to appear with rapid developments in the theories and technologies in tissue engineering. Numerous types of stem cells have been isolated from dental tissue, such as dental pulp stem cells (DPSCs), stem cells isolated from human pulp of exfoliated deciduous teeth (SHED), periodontal ligament stem cells (PDLSCs), stem cells from apical papilla (SCAPs), and dental follicle cells (DFCs). All these cells can regenerate the tissue of tooth. This review outlines the cell types and strategies of stem cell therapy applied in tooth regeneration, in order to provide theoretical basis for clinical treatments.
