Objective:To explore the effect of family history of cancer on clinical features and prognostic factors in nasopharyngeal car-cinoma (NPC) patients. Methods:The clinical data of 89 NPC patients with a family history of cancer and 388 NPC patients without a family history of cancer were retrospectively reviewed. Univariate and multivariate survival analyses were performed to identify possi-ble prognostic factors. Results:The clinical characteristics of NPC patients with and without family history of cancer were compared. The gender, age, TNM stage, pathological type, and hemoglobin radiotherapy concentration before treatment did not significantly dif-fer between the two groups (P>0.05). NPC patients with a family history of cancer had better 3-year overall survival than those with-out family history of cancer (91.6%vs. 85.5%), but no statistically significant difference was observed (P=0.211). Both univariate and multivariate analyses showed that T, N, and TNM stages were the important prognosis factors affecting 3-year overall survival (OS), progression free survival (PFS), and distant metastasis-free survival (DMFS) of NPC (P<0.05). However, neither family history of cancer nor family history of NPC in 3-year OS, PFS, LRFS, and DMFS was significant in NPC patients (P>0.05). Conclusion:NPC patients with family history of cancer had better 3-year OS than those without family history of cancer, but no statistically significant observation was found. Large T stage or high lymph node stage contributed to poor survival of NPC. Family history of cancer had no significant in-fluence on the survival of NPC patients.

Multiple sclerosis (MS) is an immune-mediated disease characterized by inflammatory demyelinating lesions of the central nervous system. It is one of the most common causes of neurological disability in young and middle-aged people. Clarifying the diagnosis and clinical classification of MS is very important for the early treatment and treatment strategy selection of MS patients. After fully collecting objective clinical evidence and excluding other differential diagnosis, clinicians can evaluate the dissemination in space and time of MS patients in reference to the current diagnostic criteria, and can make treatment strategy selection according to their clinical classification criteria. At present, more examination techniques and evaluation methods for MS diagnosis are being studied and discussed. It is believed that the sensitivity and specificity of MS diagnosis will be further improved in the future.

Objective To explore and analyze the impact on the delivery quality of the midwife accompanied. Methods One hundred and twenty puerperal from November 2012 to November 2013 in the thematernity department of our hos-pital were selected as the research objects,they were randomly divided into the experiment group and the control group,the control group were given the normal maternal care personnel shift system, while the experiment group ma-ternal were given the one-to-one accompanied by midwives , assisting in childbirth puerperal. The women complica-tions and two modes of nursing satisfaction of two groups were compared. Results The pain, bleeding, abnormal labor, fetal asphyxia probability and negative emotions in the experiment group were significantly lower than that of the con-trol group, while the maternal satisfaction rate of the experiment group was significantly higher than that of the control group(P<0.05). Conclusion Implements of the one-to-one for maternal the whole nursing model can effectively avoid the maternal complications and more beneficial to the health of the fetus birth and improve maternal satisfaction ,it is beneficial to the improvement of the overall quality of care for maternal and infant and worty of proper clinical promo-tion.

Background: and Purpose Patients presenting with clinical characteristics that are strongly suggestive of neuromyelitis optica spectrum disorders (NMOSD) have a high risk of developing definite NMOSD in the future. Little is known about the clinical course, treatment, and prognosis of these patients with likely NMOSD at disease onset. Methods: This study prospectively recruited and visited 24 patients with the limited form of NMOSD (LF-NMOSD) at disease onset from November 2012 to June 2021. Their demographics, clinical course, longitudinal aquaporin-4 immunoglobulin G (AQP4-IgG) serology, MRI, therapeutic management, and outcome data were collected and analyzed. Results: The onset age of the cohort was 38.1±12.0 years (mean±standard deviation). The median disease duration was 73.5 months (interquartile range=44.3–117.0 months), and the follow-up period was 54.2±23.8 months. At the end of the last visit, the final diagnosis was categorized into AQP4-IgG-seronegative NMOSD (n=16, 66.7%), AQP4-IgG-seropositive NMOSD (n=7, 29.2%), or multiple sclerosis (n=1, 4.2%). Seven of the 24 patients (29.2%) experienced conversion to AQP4-IgG seropositivity, and the interval from onset to this serological conversion was 37.9±21.9 months. Isolated/mixed area postrema syndrome (APS) was the predominant onset phenotype (37.5%). The patients with isolated/mixed APS onset showed a predilection for conversion to AQP4-IgG seropositivity. All patients experienced a multiphasic disease course, with immunosuppressive therapy reducing the incidence rates of clinical relapse and residual functional disability. Conclusions Definite NMOSD may be preceded by LF-NMOSD, particularly isolated/ mixed APS. Intensive long-term follow-up and attack-prevention immunotherapeutic management is recommended in patients with LF-NMOSD.

Objective:To compare the differences in radiation dose and image quality between cone-beam CT (CBCT) and multi-slice spiral CT (MSCT) applied to atlantoaxial spine imaging.Methods:Head and neck phantom was scanned at 30 exposure parameter combinations using Pramerica CBCT scanner and 15 parameter combinations using Toshiba 320-row MSCT. The effective dose ( E) of CBCT was calculated based on the Monte Carlo dose estimation software PCXMC, the E value of MSCT was obtained by multiplying the dose length product (DLP) by the related factor. t-test for two independent samples or Wilcoxon rank sum test were used for comparison of radiation dose and subjective and objective image quality between two modalities. The subjective evaluation was a 5-point subjective scale using double-blind method for edge sharpness, contrast, soft tissue level, and artifacts of the images. The signal and noise in the region of interest (ROI) were measured and the contrast signal-to-noise ratio (CNR) was calculated. Results:For radiation dose, the volumetric dose index and E values of 2.9 mGy and 27.61 μSv for CBCT were lower than those of 8.8 mGy and 433.16 μSv for MSCT, and the differences were statistically significant( z=-3.05, -5.25, P<0.05). For objective evaluation of image quality, the noise and CNR were 27.74 HU and 3.69 in CBCT group, 7.84 HU and 27.1 in MSCT group. The difference between them were statistically significant( z=-5.39, -5.42, P<0.05). The overall image quality, contrast and artifact scores of the CBCT group were 3.5, 3.0 and 5 were higher than those of the MSCT group at 2.0, 2.0, and 4.0, respectively ( z=-2.32, -2.46, -3.31, P<0.05). Conclusions:Both atlantoaxial CBCT and MSCT scans provide image quality that meets diagnostic requirements. Compared to MSCT, CBCT atlantoaxial scans can effectively reduce radiation dose according to the principle of optimization of radiation protection.

Objective To study the compliance of forbidden depasturing livestock on the marshland with Oncomelania snails in schistosomiasis endemic areas. Methods According to 3 levels of human infection rates as > 10% ,5%-10% and <5% , 2 204 residents selected randomly from the schistosomiasis endemic villages were sampled with the stratified cluster sampling method in Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Sichuan and Yunnan provinces, and investigated by questionnaire. The contents of the questionnaire included the recognition and implementation of forbidden depasturing livestock on marshland with Oncomelania snails and breeding livestock in bam. Results A total of 78.4% residents agreed forbidden depasturing livestock on marshland with snails, but 3. 7% residents disagreed it. A total of 83. 9% residents considered the relationship between breeding livestock in bam and schistosomiasis control, but 3. 1% residents thought that it was no relationship. The main reasons of depasturing livestock on marshland with Oncomelania snails were the high cost of breeding livestock in bam (36. 2% ) , unaccustomed (26.4% ) and no room for breeding livestock in bam (25.4% ). Conclusion Forbidden depasturing livestock on the marshland with Oncomelania snails should be strengthened according to the local economic, nature environment, agriculture, residents'culture degree and agriculture habit.

Hyperlipidemia is characterized by elevated levels of blood lipids. The clinical manifestations are mainly atherosclerosis caused by the deposition of lipids in the vascular endothelium. The link between abnormal lipid metabolism and sudden hearing loss remains unclear. This article presents a case study of sudden hearing loss accompanied by familial hyperlipidemia. Pure tone audiometry indicated intermediate frequency hearing loss in one ear. Laboratory tests showed abnormal lipid metabolism, and genetic examination identified a heterozygous mutation in theAPOA5 gene. Diagnosis: Sudden hearing loss; hypercholesterolemia. The patient responded well to pharmacological treatment. This paper aims to analyze and discuss thepotential connection between abnormal lipid metabolism and sudden hearing loss.
