Objective:To analyze the prognostic factors of patients with Ⅰ B1-Ⅱ A cervical cancers after surgery and to assess the effects and adverse reactions of intensity-modulated radiotherapy(IMRT)combined with concurrent chemotherapy(CCRT). Methods:A retrospective analysis was performed based on the clinical and follow-up data of 362 patients with Ⅰ B1-Ⅱ A cervical cancers who were treated in Changzhou Second People′s Hospital from January 2009 to December 2019. Meanwhile, these patients suffered large primary tumors(LPT; tumors size: ≥4 cm), lymphatic vascular space invasion (LVSI), and deep stromal invasion(DSI; stromal infiltration depth: ≥1/2) after surgery and showed at least one intermediate-risk factor. Among these cases, 161 cases were treated with CCRT, 131 cases under-went single radiotherapy (RT), and 70 cases received unadjuvanted radiotherapy. The Kaplan-Meier method and the logrank test were adopted for univariate survival analysis, the binary logistic regression was used to analyze the recurrence risk, and Cox regression model was used for multivariate survival analysis. Results:The 3 and 5-year overall survival (OS) rates were 94.20% and 88.39%, respectively. The retrospective analysis showed that the risk factors of recurrence included tumor size ≥ 4 cm and poorly differentiated cancers( OR=3.287, 2.870, 95% CI: 1.366-7.905, 1.105-7.457, P<0.05). Compared with the treatment without adjuvant radiotherapy and RT, CCRT reduced the recurrence rate of tumors with tumor size of ≥ 4 cm, adenocarcinomas or adenosquamous carcinomas (pathological types), and poorly differentiated carcinomas( χ2=6.725-7.518, P<0.05). A multivariate analysis showed that the CCRT improved the recurrence-free survival ( HR=0.290, 95% CI: 0.128-0.659, P=0.003) and OS ( HR=0.370, 95% CI: 0.156-0.895, P=0.024). A subgroup analysis indicated that CCRT prolonged the OS of patients with tumor size ≥ 4 cm or poorly differentiated cancers compared to the patients receiving no radiotherapy or those treated with RT (χ 2=7.614, 5.964, P<0.05). Compared with the cases receiving single radiotherapy, those receiving CCRT did not suffer an increase in the incidence of hematology, radiation enteritis, and cystitis above grade 3 according to observation ( P>0.05). Conclusions:Among the intermediate-risk factors leading to the recurrence of postoperative cervical cancers, the factors of large primary tumors or poorly differentiated cancers affect the prognosis of patients.Compared with RT and the treatment without adjuvant radiotherapy, IMRT combined with concurrent chemotherapy can prolong the recurrence-free survival and overall survival of patients with large tumors or poorly differentiated cancers and adverse reactions induced are tolerable.

Objective: To explore the clinical and radiological features of myelin oligodendrocyte glycoprotein (MOG) antibody associated disease. Methods: The clinical data of 22 MOG antibody associated disease cases treated in the Department of Neurology, Qilu Hospital of Shandong University from January 2017 to June 2019 were retrospectively analyzed. The clinical data of MOG antibody associated disease were summarized, including clinical and imaging features. Results: Of the 22 included patients with MOG antibody associated disease, the average age was 38.5 years, 13 were male and nine were female. Among them, 11 cases manifested as aquaporin-4 (AQP4)-negative neuromyelitis optica spectrum disorder (NMOSD), four cases optic neuritis, two cases transverse myelitis, one case acute disseminated encephalomyelitis (ADEM), two cases cortical encephalitis and two cases vestibular neuronitis. Magnetic resonance imaging (MRI) results showed that multiple anatomical areas were involved. Among the nine patients with optic nerve involvement, five patients had longitudinally extensive optic nerve lesions, which were longitudinally enhanced. In eight patients, MRI lesions in the spinal cord showed mostly long or short segments involvement, involving 2-5 spinal cord segments. Five cases involved the cervical spinal cord, six cases involved the thoracic spinal cord, and one case involved the lumbar spinal cord. Brain MRI abnormalities were found in 13 cases and the lesions were mostly patchy and point-shaped. MRI lesions demonstrated T₂ hyperintensity and some of them could be strengthened, which may involve the basal ganglia, thalamus, radiographic crown, frontal temporal lobe, brain stem and other parts. Among them, 16 patients were sensitive to high-dose intravenous/oral methylprednisolone in the acute phase. Seven patients had recurrence after two months to two years of follow-up. Conclusions MOG antibody associated disease include multiple manifestations. Among them, AQP4-negative NMOSD is the most common form. The clinical manifestations of patients showed diversity. Imaging is characterized by multiple parts involvement such as optic nerve, spinal cord, and brain. Most patients are sensitive to high-dose intravenous/oral methylprednisolone, and have a good prognosis in the acute phase, but some patients may relapse.

Objective:To investigate the clinical features, imaging features, gene diagnosis, treatment and prognosis of autosomal dominant lateral temporal epilepsy (ADLTE) with heterozygous RELN mutation.Methods:Clinical data of an ADLTE family caused by a heterozygous mutation in the RELN gene diagnosed in September 2019 at Qilu Hospital of Shandong University were collected. The clinical characteristics of ADLTE were analyzed, and literature review was conducted.Results:The male proband, 22 years old, was admitted with the clinical manifestations including seizures begun at temporal lobe, which specifically manifested as a sudden emergence of binaural hum, lasting for more than 10 seconds, and the symptoms can self-recover quickly. Half a month later, generalized tonic-clonic seizures attacked subsequently after a similar auditory aura. There were no abnormal findings in interictal electroencephalography (EEG) and magnetic resonance imaging (MRI). Following the family history, his father had similar auditory symptoms around the age of 20, and occasional secondarily generalized tonic-clonic seizures appeared. Antiepileptic drug can control better. The whole exome sequencing of three people in the family revealed that both the proband and his father had NM-005045: c.6068T>C heterozygous mutation in the RELN gene.Conclusions:ADLTE mostly occurs in juveniles or early adulthood. The main clinical manifestations are focal seizures with auditory auras, which can be followed by generalized tonic-clonic seizures. There are no abnormal findings in the interictal EEG and MRI. ADLTE is sensitive to drug treatment and has good clinical prognosis. The study identified a novel heterozygous mutation NM-005045: c.6068T>C in RELN gene, which is responsible for the development of ADLTE.

Objective:To seek survival-related genes in glioblastoma and establish a survival-gene signature for predicting prognoses of glioblastoma using public databases.Methods:Three independent glioma databases (GEO GSE53733,CGGA,TCGA) with whole genome expression data were included for analysis.Survival-related genes were obtained by comparing the long-term (＞36 months) and short-term (＜12 months) survivors in the database GSE53733.CGGA was used as the training set to develop the signature and TCGA was used asthe validation set.Cox regression analysis and linear risk score assessment were conducted to look for prognostic signatures with survival-related genes.Principal components analysis,gene set enrichment analysis (GSEA),gene ontology (GO) and protein-protein interaction (PPI) analysis were performed to explore distinct expression profiles between risk grouped glioblastoma.Results:We totally found 211 survival-related genes and developed a signature with 17 survivalrelated genes for prognosis of glioblastoma.Based on this signature,the low-risk group had longer survival time while the high-risk group had shorter survival time.Additionally,the expression profiles between the high-risk and low-risk glioblastoma were different.Functional annotations revealed that the genes enriched in the high-risk glioblastoma were involved in immune systems and processes of extracellular matrix (ECM).Conclusion:The novel survival-gene signature can predict high-risk glioblastoma with shorter survival time,enhance immunosuppressive features,and increased invasion preferences.

Objective To evaluate the treatment outcomes and toxicities of intensity-modulated radiation therapy (IMRT) combined with chemotherapy for children and adolescents with nasopharyngeal carcinoma.Methods Forty-three nasopharyngeal carcinoma patients less than 19 years old were recruited between April 2010 and April 2016.All patients were treated with IMRT (total dose 61.2-76 Gy) combined with cisplatin based chemotherapy.The Kaplan-Meier test was used to calculate overall survival (OS) and progression-free survival (PFS).The patient's clinical characteristics,side effects and longterm effects of treatment were retrospectively analyzed.Results Among 43 patients,there were 29 (67.4％) male and 14 (32.6％) female,and the median age was 14 years old (range,6-18 years).According to AJCC 7thstaging system,2 patients were in stage Ⅱ,26 in stage Ⅲ,7 in stage ⅣA and 8 in stage Ⅳ B.All patients were confirmed as non-keratinizing carcinoma.The positive rates of EB virus VCAIgA was 53.8％ (7/13),and Rta-IgG was 60.0％ (6/10) before treatment.The median radiation dose was 70 Gy (range,61.2-76 Gy) to the primary tumor.Thirty-three (76.7％) patients received neoadjuvant chemotherapy,with 20 (46.5％) and 36 (83.7％) patients treated by concurrent and adjuvant chemotherapy,respectively.With a median follow-up of 24 months (range,3-76 months),the 5-year OS and PFS ratios were 75.3％ and 64.7％,respectively.There were 5 patients (11.6％) occurred to bone metastasis within 2 years after treatment.Hypothyroidism was reported in 47.4％ (9/19) patients after IMRT.Conclusions Nasopharyngeal carcinoma in childhood and adolescence is mostly locally advanced diseases with poor differentiation.IMRT combined with chemotherapy produce a well treatment outcome with good tolerance in children and adolescents patients.The most common treatment failure bone metastasis.Radiation-induced hypothyroidism is common.

Objective To prospectively study the dynamic variation of vascular endothelial growth factor (VEGF),the short-term efficiency and the tolerability of the esophageal cancer patients treated by radiotherapy combined with thalidomide.Methods The serum samples of 86 esophageal cancer patients were collected before,during and after the radiotherapy.The VEGF levels were assayed by enzyme-linked immunosorbent assay (ELISA).3 patients interrupted the treatment because of intolerance radiotherapy.Based on the changes of VEGF level,32 esophageal cancer cases whose VEGF levels increased or remained were assigned to the group to which thalidomide was given during the whole course of radiotherapy.The rest 51 patients whose VEGF level decreased received radiotherapy without thalidomide during the whole course.In addition,30 healthy cases were included in control group.Then the efficiency and safety of the introduction of thalidomide in radiotherapy were investigated. Results The VEGF levels of 86 esophageal cancer cases were significantly higher than the 30 healthy control cases ( t =5.07,P ＜ 0.01 ),which were also correlated with the primary tumor size ( t =4.55,P ＜ 0.01 ),lymph node metastasis ( t =7.50,P ＜0.01 ),histological type( F =3.40,P ＜ 0.01 ) and clinical stage ( t =2.52,P ＜ 0.0 l ).However,it was irrelevant to the lesion site,distant metastasis,X-ray pathologic type,gender or age ( P ＞ 0.05).For the thalidomide involved group, the VEGF level after radiotherapy was significantly lower than during radiotherapy (t =2.37,P ＜0.05 ) with an effective rate of 71.88％.For the rest 51 cases without using thalidomide,the effective rate was 78.43％ yet there was no significant difference between the VEGF levels during and after radiotherapy ( t =0.18,P ＞ 0.05 ).62.50％ patients reported symptoms of dizzy and burnout after using thalidomide,while this incidence was 15.69％ for the rest patients (x2 =19.28,P =0.000).For the groups with or without thalidomide combination,the sleepiness incidences were 18.75％and 1.96％,respectively (x2 =5.168,P =0.023 ); the Ⅲ - Ⅳ grade esophagitis incidences were 12.50％ and 11.76％,respectively (x2 =0.061,P =0.806) ; the Ⅱ - Ⅳ grade leukocyte decrease incidences were 6.25％ and 9.80％,respectively (x2 =0.026,P =0.872) ; the Ⅲ - Ⅳ grade platelet descend incidences were 3.13％ and 5.88％,respectively (x2 =0.002,P =0.965 ) ; the Ⅲ - Ⅳ grade nausea and vomiting incidences were 9.38％ and 27.45％,respectively (x2 =2.913,P =0.088 ). No anaphylaxis was observed. Conclusions Thalidomide can decrease the VEGF expression level of esophageal cancer patients.Patients treated with thalidomide show good tolerance and compliance.

Objective To investigate the changes and clinical value of serum vascular endothelial growth factor (VEGF) level before,during and after radiotherapy in patients with esophageal carcinoma.Methods The sera of 67 esophageal carcinoma patients and 30 healthy control cases were collected.The VEGF level in serum samples were measured with enzyme-linked immunosorbent assay (ELISA) method.The relations among VEGF level changes,clinical stages and radiotherapy effect were analyzed.Results The VEGF levels of patients with esophagus cancer before,during and after radiotherapy were significantly higher than those in control group ( F =11.65,P ＜ 0.01 ).The VEGF level after radiotherapy was significant lower than that before radiotherapy ( F =10.72,P ＜ 0.01 ).The average VEGF level of patients with T3 and T4 was significantly higher than that of control group ( F =14.10,P ＜ 0.01 ).The average VEGF level of patients with N1 and N2 was significantly higher than that of control group( F =8.64,P ＜0.01).In 62 patients,the serum VEGF level increased in 21 cases but decreased in 41 cases after radiotherapy.With difference in radiotherapy efficiency of 61.90％ and 90.24％,respectively(x2 =6.08,P＜ 0.05).The average VEGF level during and after radiotherapy for 50 cases of CR + PR were significantly lower than that before radiotherapy( F =7.98,P ＜ 0.01 ).Conclusions Monitoring the serum VEGF level of patients with esophagus cancer can help evaluate the radiosensitivity,which has a significance in predicting the prognosis of radiotherapy.

Objective: To investigate the variation of γδ T cells from healthy human peripheral blood(PB)and neonatus cord blood (CB)in proliferation and subtypes with isopentenyl pyrophosphate(IPP), and to acquire enough γδ T cells possessing distinct characteristics for experimental study.Methods: Mononuclear-cells from peripheral blood and cord blood induced by IPP were stained separately with monoclonal antibodies,which were fluorescein-labeled,and then used for assaying the expressing condition of surfaco molecules,as well as to evaluate the variation of γδ T cells on the percentage, subtypes and pbenotypes by FCM.Results:γδ T cells only account for a small proportion in both PB and CB.However,there was a significant difference in the heterogeneity between peripheral blood and cord blood γδ T cells.Vγ9Vδ2 T cells were dominant in peripheral blood γδ T cells.Most of Vγ9Vδ2 T cells in fresh isolated PBMC were central memory-type(CD27~+ CD45RA~-)and effector memory-type(CD27~-CD45RA~-)with IPP, PB γδ T cells proliferated strongly;The effector memory-typo(CD27~-CD45RA~-)turned into the main subtype in all Vγ9Vδ2 T cells,and HLA-DR and B7 molecules were highly expressed on the populations.But the cord blood γδ T cells showed rather complex subgroup heterogeneity,and Vγ9Vδ2 T cells were almost na(i)ve-type(CD27~+ CD45RA~+); Though γδ T cells were expanded(the percent of γδ T cells was increased),and Vγ9Vδ2 T cells were differentiated towards central memory-type and effector memory-type on day 14 with IPP,most of γδ T celLs still remained in the phase of na(i)ve-type(CD27~+ CD45RA~+).Conclusion:Tbere lies great differences of γδ T cells in quantity and subtypes between healthy person peripheral blood and neonatus cord blood.Peripheral blood γδ T cells can be activated and proliferated with IPP, while cord blood γδ T cells have the potential to deferentiate into director memory-type which can be used for experimental and clinical study with the synergy of corresponding cytokines.The immuno-regulation and effector function will be reported in other papers.

Objective To analyse the rate of coincidence to suspected coronary artery disease (CAD) patient between positive exercise treadmill testing (TET) and coronary angiography (CAG) test.Method Two hundred and sixty-eight chest pain patients positive in TET were performed CAG test,coronary stenosis exceed 50% was diagnosed CAD. Results One hundred and seventy-six patients (65.67%) was diagnosed by CAG, 105 male and 71 female in them. Ninety-two (34.33%) patients was negative in CAG test. The false positive rate of TET between post-menopause patients (30.12%, 25/83 ) andmale patients (28.08%, 41/146) was no significant difference(P > 0.05 ); the difference of false positive rate between pro-menopause patients (66.67%, 26/39) and male patients (28.08% ,41/146) was statistical significance (P < 0.01 ). Conclusions The positive rate of CAG can be greatly improved by screening the chest pain patients though TET before CAG, if the positive in TET performed CAG only. TET false positive rate of pro-menopause female is significantly higher than post-menopause female or male.
