Objective To investigate the clinical features and influencing factors of nasosinusitis caused by nasopharyngeal carcinoma (NPC) radiotherapy. Methods The clinical data of 228 NPC patients admitted to our hospital from January 2014 to June 2017 were retrospectively analyzed. According to whether the patients were treated with radiotherapy, the patients were divided into non-radiotherapy group (106 cases) and radiotherapy group (122 cases). The clinical characteristics of nasosinusitis were analyzed and compared. Univariate and multivariate logistic analysis was used to analyze the influencing factors of nasosinusitis after radiotherapy in patients with nasopharyngeal carcinoma. Results The incidence of sinusitis was 81.97% in the radiotherapy group, which was higher than that in the non-radiotherapy group (54.72%). The difference was statistical significance (P<0.05). The incidence of sinusitis involvement in the radiotherapy group was in the order of ethmoid sinus, sphenoid sinus, anterior ethmoid sinus, sinus ostium and nasal tract sinus complex, frontal sinus, and maxillary sinus. The incidences of ethmoid sinus and sphenoid sinus in the post-nasal sinusitis group were higher than that in the non-radiotherapy group (P<0.05). Univariate analysis showed that the occurrence of sinusitis after radiotherapy was related to whether the patient's age was > 50 years, whether the disease duration was >2 years, whether there was nasal invasion, tumor staging, whether nasal drops were used, and whether nasopharyngeal irrigation was performed. Multivariate logistic regression analysis showed that patients with a disease course of >2 years had nasal invasion and T3+T4 tumors were independent risk factors for sinusitis after NPC radiotherapy; use of nasal drops and nasopharyngeal washing were protective factors. Conclusion There is a higher incidence of sinusitis after radiotherapy of NPC, and mainly affects the ethmoid sinus and sphenoid sinus in the posterior group. Patients with a disease course of >2 years, with nasal invasion, and T3+T4 tumors should actively take measures to prevent the occurrence of sinusitis. The use of nose drops and nasopharyngeal washing is an effective measure to prevent the occurrence of sinusitis after NPC radiotherapy.

Objective To investigate the effect of scientific nutrition management after discharge on neonatal physical catch-up after intestinal operation, and to analyze the related factors affecting physical catch-up. Methods Individualized nutritional feeding instruction and nutrition consultation were performed on infants and community infants after discharge from hospital through nutrition clinic. The monthly body weight, body length and head circumference were compared between the two groups, and followed up to 9 months old. The growth trend of the two groups in half a year after birth was tested by repeated measurement. Results At the first month of age, the body weight, body length and head circumference of the patients in the operation group were lower than those in the control group (P<0.001, P=0.004, P=0.008). At the second month, the body weight and head circumference of the operation group were still behind those of the control group (P=0.003, P=0.031), and at the fourth month of age, the weight and head circumference of the patients in the operation group were still lower than those in the control group. The body weight of the operation group was lower than that of the control group (P=0.012), and there was no diffence in the physical indexes between the two groups at the age of 5~9 months. There was no statistical significance in growth trend between the two groups within half a year after birth. The growth of body length in the first half of the year had a negative correlation with the length of birth, parents' culture and father's bad habits. The growth of head circumference had a negative correlation with the length of stay in hospital, and had a positive correlation with the physical condition at birth and at first visit. Conclusion Reasonable feeding is beneficial to the physical catch-up of the newborn after intestinal operation and helps them approach the normal growth curve. Reoperation may be the main cause of weight loss, but it does not affect the normal growth of body length and head circumference. The physical condition at birth and medical visit, parents' education level, bad habit and hospitalization days were all related factors of physical catch-up.

Methods Total of 179 patients with acute myocardial infarction in Guangzhou First People's Hospital from Jan 2016 to Dec 2016 were enrolled. MACE was defined as malignant arrhythmia, recurrence of myocardial infarction, target vascular reconstruction, acute left heart failure, stroke, cardiac shock and death.Baseline data and in-hospital clinical adverse events were compared among two groups. All patients were divided into two groups:MACE(+) group and MACE(-) group. Univariate and multivariate logistic regression was used to assess the correlation between NLR and in-hospital MACE. Results In-hospital MACE occurred in 46(25.7%)patients. Univariate logistic analysis showed that NLR was strongly related with MACE incidence(OR=1.079,95%CI:1.014～1.147, P＜0.05). Multivariate logistic regression analysis found that after adjusting other traditional risk factors including female gender, age, hypertension,diabetes, overKillip II grade, systolic blood pressure,first white blood cells after admitted,basic renal dysfunction,Hs-CRP,LVEF and multivessel lesions. NLR was still a significant independent predictor of in-hospital MACE in patients with acute myocardial infarction. Additionally, hs-CRP and LVEF<50% were also associated with in-hospital MACE(P＜0.05). Conclusion NLR is the independent risk factor for in-hospital MACE occurrence in acute myocardial infarction at the early admission.

Objective To explore the effect of autologous pericardial transplantation for treating the myocardial infarction (MI) in experimental rats. Methods 30 SD rats were randomly divided in to three equal parts: Pericardial removal group (PR group): only pericardium tissue was removed; Myocardial infarction group (MI group): the anterior descending branch ligation method established a rat model of myocardial infarction and only opened the chest after 3 weeks. Autologous pericardium transplantation (APT group): After established the MI model of SD rats, 3 weeks later, the autologous pericardial patch was harvested and transplanted to infarcted zone. Four weeks after the surgery, the cardiac function and serum biochemistry were analyzed for all the experimental rats. The cardiac function was evaluated by echocardiography, which the size of the infarction were examined by Masson staining, the survival time of transplanted autologous pericardial and angiogenesis were measured by immunohistochemistry, the protein expressions of Caspase and the gene expressions of Bcl were examined by Western blot analysis. Results 4 week after the 2^nd operation, no ventricular fibrillation was detected in the ECG of PR group. Fatal ventricular fibrillation wasn't detected in the ECG of MI group and APT group. Compared with MI group, APT group improved cardiac function and decreased myocardial apoptosis index(P<0.05),which similar to PR group. APT group has the higher density of angiogenesis at infracted area to MI group but less than that of PR group. PT group had decreased protein expressions of Caspase-3 and the expressions of Bcl-2 were decreased. Conclusion Autologous pericardial transplantation could recover myocardial infarction cells, which will improve the cardiac function in experimental rats with MI.

Objective To analyze the efficiency and clinical value of noninvasive prenatal gene test (NIPT) in the diagnosis of fetal chromosomal aneuploidy. Methods From April 2016 to March 2018, 3 759 pregnant women who underwent noninvasive prenatal gene testing in our hospital were selected as subjects. The second generation sequencing AR550 platform combined with bioinformatics was used for noninvasive prenatal gene testing. The NIPT detection ranged from 21, 18, 13 to sex chromosome aneuploidy. For pregnant women at high risk of NIPT, amniotic fluid or umbilical cord blood puncture karyotype analysis was recommended to compare the consistency of the two results, and follow-up pregnancy outcomes. Results Among 3 759 pregnant women, NIPT showed 27 cases of high risk, with a positive rate of 0.71%. Twenty-four pregnant women were diagnosed as 21-trisomy in 14 cases, 18-trisomy in 1 case, 13-trisomy in 1 case and abnormal sex chromosome number in 4 cases. The positive predictive values were 100%, 50%, 100% and 66.7% respectively. Among them, 99 cases were non-invasive pregnant women with NT thickening, and 5 cases were at high risk of detection. The detection rate was 5.05% (5/99), which was higher than the overall detection rate. Conclusion NIPT has high sensitivity and specificity to 21-trisomy and 18-trisomy, can improve the efficiency of prenatal screening and diagnosis, and has good clinical application value.
