Objective To explore the clinical characteristics of head deformities in infants aged 3-12 months and analyze the related factors that affect infant positional deformities.Methods A total of 521 infants aged 3-12 months from August 2022 to February 2024 in the Third Affiliated Hospital of Zhengzhou University were selected as the subjects.Infants were divided into normal groups(n=307)and positional deformities(n=214)according to the head shape assessment.The general,high-risk factors during pregnancy,mother's education level and baby's sleeping posture were compared between the two groups.Logistic regression was used to analyze the influencing factors of positional deformities.Results Among infants with positional deformities,it was more common at the age of 3-6 months,and the proportion of males was higher than that of females.There were significant differences in the factors such as birth weight,body mass index(BMI),premature delivery,hospitalization history in neonatal intensive care unit(NICU),high-risk factors during pregnancy,twins,sleeping posture,and mother's education level between two groups(P<0.05).Multivariate Logistic regression analysis showed that hospitalization history in NICU,twins,high-risk factors during pregnancy were independent risk factors for infant's positional deformities.Infant's mixed sleeping position and mother's high education level were the protective factors against the infant's positional deformities.Conclusion BMI,hospitalization history in NICU,twins,high-risk factors during pregnancy,infant sleeping posture and mother's education level are closely related to the infant's positional deformities.

Background: and Purpose We aimed to determine the clinical features of Miller Fisher syndrome (MFS) in southern China and compare them with those presenting in other countries. Methods: We collected the medical records of patients diagnosed with MFS during 2013–2016.We analyzed the age, sex, onset season, precursor events, clinical symptoms and signs, findings of nerve conduction studies (NCS), cerebrospinal fluid (CSF), therapeutic remedies, nadir time, and length of hospital stay of patients with MFS in southern China. We concurrently compared the differences between urban and rural areas and between patients with incomplete ophthalmoplegia (IO) and complete ophthalmoplegia (CO). Results: The study enrolled 72 patients: 36 from rural areas and 36 from urban areas, and 50 males and 22 females. The mean age at onset was 47.72 years, and 30 (41.7%) and 21 (29.2%) patients developed MFS in spring and winter, respectively. The typical triad of ophthalmoplegia, ataxia, and areflexia was observed in 50 (69.4%) patients. A history of upper respiratory tract infection 1 week before onset was found in 52.8% of the patients, while 5.6% experienced gastrointestinal infections and 48 (73.8%) exhibited albuminocytological dissociation in the CSF study. Only 26 (36.1%) patients presented abnormalities in NCS. Moreover, restricted outward eyeball movement presented in 83.5% of the patients with classic MFS and acute ophthalmoplegia, and bilateral symmetrical ophthalmoplegia presented in 64.2%. With the exception of the higher proportion of NCS abnormalities in urban areas (47.2% vs. 25.0%), urban and rural differences were insignificant regarding sex ratio, age at onset, high-incidence season, precursor events, disease characteristics, and albuminocytological dissociation in the CSF. Furthermore, patients with CO were older than those with IO (64.53±7.69 vs. 43.19±14.40 years [mean±standard deviation], p<0.001). Conclusions The patients with MFS were mostly male and middle-aged, and most presented in winter and (especially) spring. More than half of the patients had clear precursor events, most of which were classic MFS with the typical triad. More than 70% of the patients presented albuminocytological dissociation in the CSF. NCS abnormalities were uncommon in MFS. The age at onset was lower in patients with IO than in patients with CO; bilateral symmetrical extraocular muscle paralysis was the most common symptom, and the external rectus was the most frequently involved muscle.

OBJECTIVE:To investigate the correlation of XRCC1 rs25487 polymorphism with the occurrence of lung cancer. METHODS:A total of 208 patients with primary lung cancer of Han nationality in Northern Jiangsu selected from the Affiliated Hospital of Xuzhou Medical University during Sept. 2015-Jul. 2016 were included in lung cancer group. A total of 214 healthy volunteers of the hospital underwent physical examination were included in control group. PCR-RFLP was used to detect the genotypes at XRCC1 rs25487 locus,and Logistic regression model was used to evaluate the correlation of genotypes with the occurrence of lung cancer. RESULTS:There was no statistical significance in the distribution of age and gender between 2 groups (P＞0.05). The proportion of smoker in lung cancer group was significantly higher than control group,with statistical significance(P＜0.05). AA,AG and GG genotypes were detected at rs25487 locus of XRCC1 gene. The frequency of AA,AG and GG genotype were 43.5%,41.1%and 15.4% in control group and 28.8%,48.6% and 22.6% in lung cancer group,respectively. The frequencies of genotypes in 2 groups were in line with Hardy-Weinberg equilibrium(P＞0.05),but there was statistical significance in genotype distribution between 2 groups(P＜0.05). Compared with AA genotype,the risk of lung cancer in individuals carrying AG genotype increased by 2.265 fold [OR＝2.265,95%CI(1.299,3.950),P＝0.040;after corrected with gender,age and smoking history OR＝2.309,95%CI(1.274, 4.185),P＝0.006],with statistical significance. The risk of lung cancer in individuals carrying GG genotype increased by 1.310 fold [OR＝1.310,95%CI(0.771,2.228),P＝0.318;after corrected OR＝1.429,95%CI(0.811,2.518),P＝0.217],without statistical significance. CONCLUSIONS:rs25487 locus mutant heterozy-gosity of XRCC1 gene is risk factor of lung cancer in Han nationality from Northern Jiangsu,and smoking can increase the risk of lung cancer.
