Objective The objective of this study was to investigate the clinicopathological features and rational treatment of primary fallopian tube cancer(PFTC).Methods The clinical and pathological data of 39 patients with primary fallopian tube cancer from January 2006 to July 2016 in Beijing Tongren Hospital of Capital University were retrospectively analyzed.Results There were 39 cases of undifferentiated carcinoma,including 1 case of undifferentiated and transitional cell carcinoma,37 cases of undifferentiated adenocarcinoma,or 29 cases of simple adenocarcinoma and 10 cases of mixed type.Among them,7 cases were treated with clear cell carcinoma,endometriosis in 2 cases,combined with transitional cell carcinoma in 1 case.Extra-pelvic metastases were the most common site of the omentum with 17 cases.The preoperative test CA125 was increased in 13 cases and 38 patients received postoperative chemotherapy.The 5-year overall survival rate of 39 patients was 51.3%.Univariate analysis showed that postoperative pathologic stage(Ⅰ~Ⅱ vs.Ⅲ,P<0.001),intraoperative residual lesion size(P<0.001),omentum metastasis(P<0.001),ovarian metastasis(P=0.034),retroperitoneal lymph node metastasis(P=0.018)and preoperative CA125 elevation(P=0.002)were associated with prognosis,while age(P=0.310)and pathological grade(P=0.663)were not associated with prognosis.Multivariate analysis showed that the number of patients with postoperative lymph node metastasis(P=0.018)and preoperative CA125 elevation(P=0.002)were correlated with prognosis(HR=1.202,95% CI:2.354~63.290,P=0.003) and pathological stage(HR=3.810,95% CI:1.202~12.079,P=0.023).They were associated with prognosis as independent prognostic factors.Conclusion Tumor pathologic staging and omentum metastasis are important prognostic factors influencing the prognosis of patients with primary fallopian tube cancer.Early diagnosis and complete operation can improve the prognosis of patients.

BACKGROUND:Herba epimedi, a traditional Chinese medicine, has a long time in dealing with various orthopedic disorders. Icarinwithmany biological activites is one of the most important compositions of Herba epimedi. OBJECTIVE:Toinvestigate the effects of icarin on osteogenic differentiation of mesenchymal stem cels and the underlying mechanisms. METHODS:Bone marrow mesenchymal stem cels were treated using icarin with or without osteogenic mediumin vitro. Osteogenic differentiation markers, including runt-related transcription factor 2, osteocalcin and osterix, were detected by real time-qPCR. Alizarin red staining was used to measure calcium nodes generated by osteoblasts induced frombonemarrow mesenchymal stem cels. The proximal tibia bone structure of rats fed with icarin (2 mgperday) for 5 weeks was detected and analyzed by MicroCT. RESULTS AND CONCLUSION:Icarin was able to promote the expression of genes related to osteogenic differentiation in the absence or presence of osteogenic induction. Icarin could obviously increase the quantity of calcium nodes whenmesenchymal stem celswere cultured in the osteogenic medium. The animal experiment showed that icarin improved formation of trabecular bone.

Objective:To explore the application effect of Jiankuai psychosomatic active therapy in the elderly perioperative patients.Methods:From March 2018 to December 2019, 387 elderly patients in the urology department of the First People′s Hospital of Lianyungang City, Jiangsu Province were selected. According to the patients in two medical groups in the same ward, 193 patients in one medical group were divided into the experimental group and 194 patients in two medical groups as the control group. The experimental group was intervened by routine perioperative nursing combined with simple and fast psychosomatic active therapy, while the control group was only intervened by routine perioperative nursing. Self rating Anxiety Scale (SAS), Rosenberg Self-confidence Scale and General Self-efficacy Scale (GSEs) were used as the evaluation indexes before and after the implementation of the two groups.Results:The SAS score of the experimental group was 31.13 ± 3.64 and that of the control group was 48.45 ± 7.72 on the 7th day after operation. The difference between the two groups was statistically significant ( t value was 16.36, P < 0.05). The effective rate of self-confidence was 98.4% (190/193) and 94.8% (183/193) in the experimental group and 86.6% (168/194) and 85.1% (165/194) in the control group on the first day and the seventh day after operation, respectively. The difference between the two groups was statistically significant ( Z values were - 3.27 and 14.66, all P < 0.05). The GSEs score of the patients in the experimental group was 26.79 ± 2.17 and that of the control group was 16.86 ± 1.90. The difference between the two groups was statistically significant ( t value was 10.19, P < 0.05). Conclusions:The application of Jiankuai psychosomatic active therapy can effectively reduce the tension and anxiety of the elderly patients during the perioperative period, increase their self-confidence and self-efficacy, effectively improve the communication efficiency between doctors and patients, and promote rehabilitation.

Objective:To investigate the effects of mixed probiotics on food allergy and the underlying mechanism.Methods:BALB/c mice on the 15 th day of pregnancy were randomly (random number table method) classified into the control group, food allergy model group and mixed probiotics group.Mice in the food allergy model and mixed pro-biotics group were subjected to ovalbumin (OVA) sensitization after birth, and those in the mixed probiotics group were then given probiotic solution by gavage from day 21 to day 35.Mice in control group were similarly given 9 g/L saline.Twenty-four hours after the last OVA sensitization, intestinal histopathological sections were prepared to observe intestinal pathological changes.Blood smears were prepared to detect eosinophil count.In addition, serum samples were collected to measure cytokine levels and OVA specific antibodies.The number of dendritic cells (DCs) and regulatory T cells (Tregs) in mouse mesenteric lymph nodes was calculated.Differences among 3 groups were compared by the One- Way ANOVA or Kruskal- Wallis H test. Results:Compared with those of food allergy model group, diarrhea score, the ratio of eosinophils and serum levels of interleukin(IL)-4, IL-5, IL-13, mast cell protease 1 (MCPT-1), and OVA specific antibodies IgE and IgG were significantly lower in mixed probiotics group[(2.00±0.71) points vs.(3.22±0.97) points, (2.28±1.61)% vs.(10.99±2.26)%, (413.68±22.81) ng/L vs.(708.78±27.66) ng/L, (36.64±3.74) ng/L vs.(46.05±4.95) ng/L, (201.37±65.61) ng/L vs.(495.22±96.66) ng/L, (31 924.15±1 177.77) ng/L vs.(36 175.77±618.29) ng/L, (9.10±8.08) ng/L vs.(19.69±0.84) ng/L, (30.50±8.81) ng/L vs.(190.32±6.40) ng/L], while IL-10 level was significantly higher[(164.12±3.88) ng/L vs.(123.90±7.31) ng/L] ( t=3.37, 8.72, 16.07, 3.90, 7.40, 7.95, 3.91, 44.00 and 7.76, respectively, all P<0.01). Compared with those of food allergy model group, programmed cell death ligand 1 (PD-L1) level on the surface of CD 103+ DCs and CD 103+ CD 80-CD 40-DCs, the proportion of Tregs in CD4 + T cells, and the level of programmed cell death 1 (PD-1) on the surface of Tregs were significantly higher in mixed probiotics group[(75.59±0.45)% vs.(45.60±4.73)%, (67.56±1.87)% vs.(37.12±6.07)%, (8.24±0.69)% vs.(6.20±0.66)%, (11.25±3.12)% vs.(4.08±2.33)%]( t=7.88, 4.48, 3.63 and 3.71, all P<0.01). Conclusions:Mixed probiotics can alleviate the symptoms of food allergy and inflammatory response of young rats through mediating Tregs via the PD-1/PD-L1 pathway.

Objective To summarize the clinical and electroencephalogram features of neuronal ceroid lipofus-cinosis (NCL). Methods A retrospective analysis of the clinical phenotypes and electroencephalogram features of pa-tients diagnosed with NCL in Department of Pediatrics,Peking University First Hospital from February 2000 to August 2015 were conducted. Results Among the 30 patients,18 were male and 12 were female. The age of onset was between 9 months to 7 years old. The first symptoms included seizure in 22 patients,psychomotor developmental delay or regre-ssion in 7 cases,and visual loss in 1 case. Clinical manifestations included psychomotor regression in 29 cases,epilepsy in 28 cases,visual impairment in 19 cases,ataxia in 20 patients,and positive pyramidal tract sign in 13 cases. Twenty-one patients accepted fundus oculi examination. Seven patients were found with macular degeneration,8 cases with optic nerve atrophy,2 cases with retinal pigment degeneration,and 8 patients were normal. Brain atrophy were found in all 30 cases,including diffuse brain atrophy in 14 cases,only cerebellar atrophy in 6 cases,and cerebral atrophy with periven-tricular T2W high signal in 10 cases. Video electroencephalogram(EEG)examination was performed in 27 patients and their backgrounds were diffuse slow waves. Seven patients didn't have physiological vertex sharp waves or sleep spin-dles. Generalized epileptiform discharges were captured in 6 cases,focal epileptiform discharges in 15 cases. Both of generalized and focal epileptiform discharges were captured in 6 cases. Generalized slow wave burst in 4 cases,and in-termittent photic stimulation evoked epileptiform discharges in 3 cases. Ten patients were observed with clinical sei-zures,including 4 cases of myoclonic episodes,3 cases of atypical absences,3 cases of focal seizures,1 case of atonic and one of tonic spasms. Peripheral blood enzyme examination was taken in 13 patients,among whom 8 patients were identified with tripeptidyl peptidase 1 (TPP1)deficiency and 1 patient with palmitoyl protein thioesterase 1 (PPT1) deficiency. Twenty-eight patients accepted skin and/or muscle electron microscope examination. Osmiophilic granular was found in 2 cases,curvilinear bodies in 15 cases,fingerprint profiles in 2 cases,curvilinear and linear bodies in 1 case,fingerprint profiles and osmiophilic granular in 1 case. NCL-related gene detection was conducted in 3 patients, with 1 patient identified with CLN6 compound heterozygous mutations and 2 patients with TPP1 homozygous mutations. Thirty patients were classified into 3 groups based on the onset age,enzymatic examination results and pathological examination of skin and muscle,including 5 cases of infantile NCL,20 cases of late-infantile NCL,and 5 cases of juvenile NCL. Conclusions The clinical features of NCL included multiple types of epileptic seizures (among which myoclonus was the most common type),psychomotor developmental delay or regression,vision loss,ataxia,and positive pyramidal tract sign. Its MRI was characterized with brain atrophy. EEG showed diffuse slow wave activity,with focal and/or generalized epileptiform discharges. Specific enzyme examination,and skin or muscle pathology or gene test could help to make diagnosis.

CaMKII is essential for long-term potentiation (LTP), a process in which synaptic strength is increased following the acquisition of information. Among the four CaMKII isoforms, γCaMKII is the one that mediates the LTP of excitatory synapses onto inhibitory interneurons (LTP_E→I). However, the molecular mechanism underlying how γCaMKII mediates LTP_E→I remains unclear. Here, we show that γCaMKII is highly enriched in cultured hippocampal inhibitory interneurons and opts to be activated by higher stimulating frequencies in the 10-30 Hz range. Following stimulation, γCaMKII is translocated to the synapse and becomes co-localized with the postsynaptic protein PSD-95. Knocking down γCaMKII prevents the chemical LTP-induced phosphorylation and trafficking of AMPA receptors (AMPARs) in putative inhibitory interneurons, which are restored by overexpression of γCaMKII but not its kinase-dead form. Taken together, these data suggest that γCaMKII decodes NMDAR-mediated signaling and in turn regulates AMPARs for expressing LTP in inhibitory interneurons.

OBJECTIVETo evaluate the therapeutic effect of methylprednisolone for electrical status epilepticus during sleep (ESES) in children.

METHODThe clinical and EEG data of 82 epilepsy patients with ESES, which included benign childhood epilepsy with centro temporal spikes (BECT) variants, epilepsy with continuous spikes and waves during slow sleep (CSWS) , Landau-Kleffner syndrome (LKS) collected from department of pediatrics, Peking University First Hospital were analyzed from July 2007 to September 2012. During ESES period, all patients received methylprednisolone treatment for three courses, which included methylprednisolone intravenous infusion for three days, followed by oral prednisone for four days every time. After three courses, prednisone [1-2 mg/(kg × d)] were taken by all patients for 6 months. The ESES phenomenon and seizures were observed before and after treatment. The efficacy of corticosteroid on ESES suppression, seizure control of three epilepsy syndrome were analyzed.

RESULTThirty-nine cases were male and 43 cases were female. The epilepsy syndromes included 49 patients diagnosed as benign childhood epilepsy with centrotemporal spike (BECT) variants, 27 patients diagnosed as epilepsy with continuous spikes and waves during slow sleep (CSWS), and 6 patients diagnosed as LKS. Age of onset ranged from 1 year and 4 months to 11 years. The age of ESES newly monitored was from 2 years to 10 years and 8 months. The total effective rate of corticosteroid was 83% (68/82) for ESES, BECT variants was 82% (40/49), CSWS was 81% (22/27), LKS was 100% (6/6). There was no statistically significant difference in effective rates between the front two (χ² = 0.09, P > 0.05). The seizures were improved in the first month after methylprednisolone treatment in 3 epilepsy syndromes. The recurrence rate of BECT variants was 47% (23/49) , CSWS was 59% (16/27) , LKS was 50% (3/6) after 1 year follow up. There was no association between disease parameters, including age at seizure onset, duration of ESES and the treatment effect of ESES examined by Kruskal-Wallis method (χ² = 3.585, 0.932, P > 0.05).

CONCLUSIONMethylprednisolone was effective for improving ESES and seizures in 3 epilepsy syndromes combined with ESES. There was no significant correlation between age at seizure onset, duration of ESES and treatment effect of ESES.
