The occurrence and severity of radiotherapy-induced adverse events cannot be accounted for or predicted by therapeutic and clinical factors alone.Evidence suggests that genetic variants are associated with adverse effects following radiotherapy.Radiation genomics is the study of genetic variants associated with radiotherapy toxicity.Radiation genomics aims to develop a risk prediction model and uncover the biological mechanisms responsible for radiotherapy toxicity.With the advances in genomics and bioinformatics in the past two decades,radiation genomics has evolved from candidate gene studies to genome-wide association studies,with a series of progress.In this review,we will discuss the study background,design,approaches,challenges,and future directions for radiation genomics.

Objective To explore the clinical value of false positive of Down’ s Syndrome Screening for premature rupture of membranes in the second trimester of pregnancy. Methods From Jan. 2009 to Jul. 2013, there were 321 cases who were in the second trimester of high risk pregnancy recieved Down’ s Syndrome Screening. Their fetals have been excluded chromosome or organ abnormality, and there was no fetal organ structure abnormal through sequence prenatal ultrasound examinations. Results of their pregnancy have been followed-up, and pregnancy outcomes of 346 cases who were of low risk were followed-up at the same time. Results Among the 321 cases, there were 14 ca-ses of abortion because of PROM ( gestational age less than 28 weeks);17 cases of premature delivery because of PROM, including 9 cases whose gestational age were from 28 to 34 weeks and 8 cases whose gestational age were from 34 weeks to 37 weeks;and 7 cases of neonatal asphyxia. In the low risk group, abortion because of PROM occured in 6 cases before 28 weeks, 3 cases between 28 to 34 weeks, and 4 ca-ses between 34 to 37 weeks, and neonatal asphyxia occured in 3 cases. Conclusion Comparing with Down’ s screening false positive preg-nant women and the low risk group, the false positive group have a higher occurrence of PROM, Down’ s screening is a potential high risk in-dex as a predictor of PROM.

Objective To investigate the inhibitory effect of matrine on inflammation by regulating Th1/Th2 bal-ance in asthmatic rats and the underlying mechanism related to SOCS3.Methods Ovalbumin-sensitized rats were established as asthma model, Animals randomly divided into four groups, as follows: control ( without any treatment) , model group, treatment group A ( low-dose matrine treated asthma rats ) and treatment group B ( high-dose matrine treated asthma rats) .The eosinophil counting, goblet cells percentage, inflammatory cell in-filtration in rat lung were analyzed and scored by morphological examination .IL-4 and IFN-γlevel in BALF were determined by ELISA and IFN-γ/IL-4 ratio was further calculated.Furthermore, the expression of SOCS3 in mRNA and protein level were detected by qRT-PCR and Western blot, respectively.Results Eosinophil count and percentage, goblet cell percentage and inflammatory cell infiltration score were significantly lower than that in treatment group A and B as compare to model group ( P<0.05 ) .The group A exhibited a lower IFN-γlevel and a higher IL-4 level ( P<0.05 ) .IFN-γlevel in treatment group A and B were higher while IL-4 level were lower as compare to model group.Meanwhile, SOCS3 mRNA level in rat lung tissue was elevated in model group.Ma-trine treatment decreased SOCS3 expression in group A and B .Similar trend was found in SOCS3 protein level. Conclusions Matrine may exhibit antiinflammatory effect by inhibiting SOCS3 expression and correcting Th1/Th2 balance in asthmatic rats.

Objective:To explore the clinical and imaging features and prognoses of myelin oligodendrocyte glycoprotein antibody associated disorders (MOGAD).Methods:Thirty-nine MOGAD patients, admitted to our hospital from January 2018 to April 2021, were chosen in our study. The clinical and imaging data and follow-up results of these patients at acute attack period (first-onset or relapse) were collected and their features were analyzed.Results:In these 39 patients with MOGAD, 20 patients (51.3%) had non-reversing course, and 19 patients (48.7%) had relapsing course. The clinical and imaging data of 55 episodes of these 39 patients were collected. In these 55 episodes, optic neuritis was noted in 27 episodes (49.1%), encephalitis was noted in 10 episodes (18.2%), brainstem encephalitis was noted in 8 episodes (14.5%), meningoencephalitis in 2 episodes (14.5%), myelitis in 3 episodes (5.5%), encephalomyelitis in 1 episode (1.8%), optic neuromyelitis in 1 episode(1.8%), optic neuritis+meningoencephalitis in 2 episodes (3.6%), and optic neuritis+encephalitis in 1 episode (1.8%). The positive rate of antinuclear antibody (ANA) was 11.1% (4/36); the cerebrospinal fluid results of 28 samples were collected from 22 patients, and CSF pleocytosis occurred in 67.9% of the samples with value of 54.89±67.70×10 6/L. Twenty-seven brain MRIs of 19 patients at the acute episode were collected; one completely normal MRI was recorded; among the remaining 26 MRIs, 6 were with one single lesion, 5 were with 2 lesions, and 15 were with 3 or more lesions; in terms of distribution, lesions involving brainstem and its adjacent structures were found in 9 MRIs, lesions involving diencephalon and deep gray matter were found in 7 MRIs, supratentorial white matter lesions were found in 13 MRIs, and cortical lesions were found in 13 MRIs. Meningeal enhancement were found in 4 contrast-enhanced brain MRIs (4/20). Long or short segmental myelitis in the spinal MRIs was noted in spinal lesions, involving cervical spinal cord, thoracic spinal cord and conus, and the "H" sign could be seen in the cross section. All patients received steroids therapy at the acute phase and the doses of steroids were tapered down gradually. Thirty-eight patients (97.4%) had good prognosis after 3 months of treatment. Conclusions:MOGAD is a disease entity widely involving the white matter, gray matter and meninges of the central nervous system with various clinical manifestations such as optic neuritis, encephalitis, brainstem encephalitis, meningoencephalitis and myelitis or a combination of the above. Immunotherapy is effective in most patients, but the recurrence rate is high, and some patients require long-term immunotherapy.

Objective:To explore the clinical characteristics of neurological syndrome associated with anti-glutamic acid decarboxylase (GAD) antibodies (Abs).Methods:Six patients with neurological syndrome associated with anti-GAD-Abs admitted to Department of Neurology, Henan Provincial People's Hospital from January 2019 to October 2022 were chosen. The clinical manifestations, imaging and laboratory results, therapeutic schedules, and follow-up prognoses of these patients were collected and summarized.Results:Three females and 3 males were included, with onset age of (54.3±17.7) years. Three patients had stiff-person syndrome (SPS), 1 had limbic encephalitis+generalized epilepsy, 1 had extralimbic encephalitis+occipital epilepsy, and 1 had cerebellar ataxia who was diagnosed with paraneoplastic syndrome associated with small cell lung cancer. Four patients had elevated level of thyroid peroxidase antibodies, and 1 patient was positive for overlapping anti-gamma aminobutyric acid B receptor antibodies and Amphiphysin antibodies. Two patients with SPS had failed lumbar puncture; 1 had slightly increased white blood cells and proteins in cerebrospinal fluid (CSF); the remaining 3 patients were basically normal. Specific oligoclonal bands in CSF were observed in 2 patients. Brain MRI showed abnormal signals in the bilateral occipital lobes in 1 patient, and no specific inflammatory lesions in other patients. All patients accepted corticosteroids and intravenous immunoglobulin/plasma exchange therapies; except for the one with paraneoplastic syndrome associated with small cell lung cancer, the remaining 5 patients had improved modified Rankin scale (mRs) scores at discharge and received long-term immunotherapy. Two patients with SPS had gradually aggravated symptoms, and mRs scores reached 5 at the last follow-up (one for 3 years and the other one for 2 years).Conclusions:The clinical manifestations of patients with neurological syndrome associated with anti-GAD-Abs include SPS, limbic encephalitis, extralimbic encephalitis, epilepsy and cerebellar ataxia; some of these patients have paraneoplastic syndromes. Immunotherapies are effective except for these patients with paraneoplastic syndromes. Some patients with SPS tend to have a chronic course and a poor prognosis.

Objective:To evaluate the safety and feasibility of applying injectable cross-linked sodium hyaluronate isolation gel in radical hypofractionated radiation therapy for prostate cancer.Methods:In this prospective study, patients at Beijing Hospital who were pathologically diagnosed with clinical stage T 1-2N 0M 0 prostatic acinar adenocarcinoma by puncture and underwent radical radiation therapy were included. All patients received ultrasound-guided cross-linked sodium hyaluronate isolation gel injection and image-guided intensity-modulated radiation therapy (IG-IMRT). The prescription dose was moderately hypofractionated, with a prescription dose of 60 Gy in 20 fractions for 5 times a week, once daily, which was delivered to 95% of the planning target volume (PTV) of prostate and seminal vesicle. Analyze the prostate rectal spacing (PRS) at the baseline, on the day of injection, during the radiotherapy, 1 month and 3 months after radiotherapy, changes in rectal volume before and after injection, and incidence of rectum-related side effects. The changes in all indexes before and after injection were analyzed by using t-test. Results:A total of 13 patients were enrolled from March 2022 to February 2023. The isolation gel maintained morphologic stability without significant spatial changes during radiotherapy, and the mid-prostate had the best effect, with PRS up to 1 cm. At 3 months after radiotherapy, the isolation gel was seen to decreased in volume with a certain absorptive capacity. The irradiated volume of rectum was decreased significantly in all patients after gel injection, and the mean volumes of rectal V 60 Gy , V 50 Gy , V 30 Gy , and V 20 Gy before and after injection were 1.923% vs. 0.280%, 10.255% vs. 3.172%, 29.602% vs. 18.800%, and 49.452% vs. 40.259% (all P<0.005). The average values (range) of rectal V 60 Gy , V 50 Gy , V 30 Gy , V 20 Gy decreases were 84.9%( 29% - 100%), 69.6%(27%-100%), 36.3%(0%-75%), and 17.8%(0%-50%), respectively. No grade 3-4 side effects occurred in all patients, and there were no common grade 1-2 rectal side effects such as diarrhea, rectal bleeding, proctitis and anal pain, etc. Only one patient developed grade 1 constipation during radiotherapy. Conclusion:Injection of Chinese made cross-linked sodium hyaluronate isolation gel can significantly reduce the irradiated volume of rectum and the incidence of rectal toxicities in prostate cancer patients undergoing radical radiotherapy.

Objective:To investigate the prognoses of pulmonary adenocarcinoma patients with leptomeningeal metastases (LM) and explore their influencing factors.Methods:A retrospective analysis was performed. The clinical data, imaging features and treatment plans of pulmonary adenocarcinoma patients with LM admitted to our hospital from January 2010 to June 2021 were collected. Overall survival (OS) was used as the prognostic evaluation criterion and patients were divided into good prognosis group (OS≥6 months) and poor prognosis group (OS<6 months) accordingly. Logistic regression analysis was used to evaluate the influencing factors for prognoses of pulmonary adenocarcinoma patients with LM. These patients were grouped according to different Karnofsky performance status (KPS) scores and different treatment methods, and survival curves were drawn to compare their OS.Results:A total of 173 pulmonary adenocarcinoma patients with LM were enrolled in the study, including 75 with good prognosis and 87 with poor prognosis. There were significant differences in the KPS scores, pulmonary adenocarcinoma lesion controlled status, giving third generation tyrosine kinase inhibitor (TKI) therapy or not, giving systemic chemotherapy and/or whole brain radiotherapy or not between the two groups ( P<0.05). Multivariate Logistic regression analysis showed that KPS scores and pulmonary adenocarcinoma lesion controlled status were independent influencing factors for prognoses ( OR=4.186, 95%CI: 1.583-11.070, P=0.004; OR=4.198, 95%CI: 1.499-11.760, P=0.006). Survival curves showed median OS of 8.2 months for all patients ( 95%CI: 6.5-9.8). The OS in patients with low-risk(KPS scores≥60) was significantly higher than that in patients with high-risk(KPS scores<60), that in patients accepted TKI treatment was significantly higher than that in patients not accepted TKI treatment, and that in patients accepted TKI and systemic chemotherapy was significantly higher than that in patients accepted TKI alone ( P<0.05). Conclusion:Patients with high KPS scores and controlled pulmonary adenocarcinoma can have relatively good prognosis; TKI treatment and combination therapy may prolong OS of these patients.

OBJECTIVETo analyze the efficacy and toxicity of concurrent chemoradiotherapy (CCRT) for patients with locally advanced non-small-cell lung cancer (LA-NSCLC).

METHODSClinical data of 251 patients with stage III (76 IIIA and 175 IIIB) NSCLC who received CCRT as initial treatment between Jan 2001 and Dec 2010 in our hospital were reviewed. A median total radiotherapy dose of 60 Gy (range, 50-74 Gy) were delivered. 174 patients were treated with IMRT, 51 with 3D-CRT and 26 with 2D-radiotherapy. EP chemotherapy regimen was administered in 112 patients, PC regimen in 99 patients, topotecan regimen in 18 patients and other regimens in the remaining 22 patients. The efficacy and toxicity of CCRT were retrospectively analyzed.

RESULTS244 patients were assessable for response, including 6 (2.5%) patients with CR, 183 (75.0%) with PR, 42 (17.2%) with SD and 13 (5.3%) with PD. At a median follow-up period of 20 months, the 1-, 3-, 5- year OS were 69.2%, 31.2%, 23.2%, respectively, and the median OS was 21 months. The 1-, 3-, 5- year PFS were 40.9%, 22.1%, 17.7%, respectively, and the median PFS was 10 months. Patients with stage IIIA NSCLC achieved better 5-year OS than that with IIIB NSCLC (29.2% vs. 20.7%, χ2=2.254, P=0.133). Failure pattern was assessable in 244 patients, including 61 (25.0%) locoregional progression alone, 55 (22.5%) distant metastasis alone and 77 (31.6%) with both. The rates of grade≥3 radiation pneumonitis, esophagitis and hematologic toxicity were 4.4%, 11.2% and 26.4%, respectively.

CONCLUSIONSCCRT provide stage III NSCLC patients favorable outcome with acceptable toxicity. CCRT is standard therapeutic approach for patients with unresectable locally advanced NSCLC.
