ObjectiveThe risk factors of relapse in 133 epileptic children after withdrawal were analyzed retrospectively and provide reference for clinical withdrawal.MethodsFrom January 2017 to March 2019, 133 children with withdrawal epilepsy were selected as the study object. According to whether there was recurrence during the follow-up period, the children with epilepsy were divided into recurrence group (42 cases) and non recurrence group (91 cases). The gender, age of onset, history of trauma, frequency of seizure before treatment, EEG before drug reduction, imaging, type of medication, family history, time of reaching control, course of disease before treatment, comorbidity, multiple attack types, withdrawal speed and EEG before treatment were observed and compared between the two groups. ResultsThere were significant differences in EEG (χ2 =7.621), medication type (χ2=8.760), time to control (χ2=6.618), course before treatment (χ2=6.435), multiple seizure types (χ2=5.443) and epilepsy comorbidity (χ2=42.795) between the two groups (P < 0.05). The results of Logistic multiple regression analysis showed that the recurrence of epileptic children after drug reduction / withdrawal was correlated with abnormal EEG before drug reduction [OR=9.268, 95%CI (2.255, 38.092)], combined drug treatment [OR=3.205, 95%CI (1.159, 8.866)] and course of disease > 1 year before treatment [OR=5.363, 95%CI (1.781, 16.150)] (P < 0.05).ConclusionsIn order to reduce the possibility of recurrence of epileptic children, the treatment time of epileptic children with abnormal EEG, combined medication and long course before treatment should be prolonged properly.
ObjectiveTo observe and analyze the risk factors of retinopathy in patients with hypertension in pregnancy.MethodsA retrospective clinical study. From January 2018 to December 2019, 260 patients with hypertension during pregnancy who were hospitalized in the Obstetrics Department of the Third Affiliated Hospital of Guangzhou Medical University were included in the study. All patients underwent fundus color photography examination. Their age, gestational age, course of hypertension, past history, number of pregnancy and childbirth, pre-pregnancy body mass index (BMI) and laboratory blood routine, alanine aminotransferase, aspartate aminotransferase, and urea Nitrogen, creatinine, uric acid, serum albumin concentration, and 24-hour urine protein concentration and urine protein content examination results were collected. Among the 260 patients, there were 60 and 200 patients with or without retinopathy in the fundus, respectively. Patients were divided into retinopathy group and no retinopathy group. The comparison of quantitative data between groups was performed by independent sample t test; the comparison of grade data was performed by Mann-Whitney U nonparametric test. The variable with statistical difference between the two groups was the independent variable, and the two-class logistic regression analysis was performed.ResultsGestational week (t=4.875), pre-pregnancy BMI (t=2.779), highest systolic blood pressure (t=－4.799), lowest systolic blood pressure (t=－4.797), highest diastolic blood pressure (t=－4.226), minimum diastolic blood pressure (t=－4.226), low and high platelet values and their fluctuations (t=7.701, 2.504, －6.083), serum albumin concentration (t=13.255), aspartic acid transaminase (t=－2.272), urea nitrogen (t=－5.117), creatinine (t=－2.735), uric acid (t=－2.130), 24-hour urine protein concentration (t=－7.801) and 24-hour urine protein (t=－7.567) were compared. The difference was statistically significant (P＜0.05). Logoistic regression analysis showed that pre-pregnancy BMI, maximum systolic blood pressure, low platelet value, and serum albumin were related to the occurrence of retinopathy of hypertension in pregnancy (P＜0.05).ConclusionHigh systolic blood pressure, low platelets, and low serum albumin are the risk factors for the occurrence of retinopathy of hypertension in pregnancy.
Objective To analysis the risk factors for lower airway bacteria colonization and ventilator-associated pneumonia ( VAP) in mechanically ventilated patients. Methods A prospective observational cohort study was conducted in intensive care unit. 78 adult inpatients who underwent mechanical ventilation( MV) through oral endotracheal intubation between June 2007 and May 2010 were recruited. Samples were obtained from tracheobronchial tree immediately after admission to ICU and endotracheal intubation( ETI) , and afterward twice weekly. The patients were divided naturally into three groups according to airway bacterial colonization. Their baseline characteristics, APACHEⅡ score, intubation status and therapeutic interventions, etc. were recorded and analyzed. Results In the total 78 ventilated patients, the incidence of lower airway colonization and VAP was 83. 3% and 23. 1% , respectively. The plasma albumin( ALB) ≤29. 6 g/L( P lt; 0. 05) , intubation attempts gt; 1( P lt; 0. 01) were risk factors for lower airway colonization. In the patients with lower airway colonization, preventive antibiotic treatment, applying glucocorticoid and prealbumin( PA) ≤ 69. 7 mg/L were risk factors for VAP ( P lt; 0. 05) . Conclusions The risk factors for lower airway colonization in ventilated patients were ALB≤29. 6 g/L and intubation attempts gt; 1. And for lower airway colonized patients, PA ≤ 69. 7 mg/L, preventive antibiotic treatment and applying glucocorticoid were risk factors for VAP.
ObjectiveTo investigate the incidence of nosocomial infection in acute and serious schizophrenic inpatients and its risk factors. MethodsBetween January 1st and December 31st, 2012, we investigated 1 621 schizophrenic patients on the status of nosocomial infections according to the hospital standard of nosocomial infection diagnosis. They were divided into infected group and uninfected group according to the survey results. The risk factors were analyzed by logistic regression method. ResultsTwenty-nine infected patients were found among the 1 621 patients, and the incidence rate was 1.79%. Among the nosocomial infections, the most common one was respiratory infection (79.31%), followed by gastrointestinal infection and urinary infection (6.90%). There were significant differences between the two groups of patients in age, hospital stay, positive and negative syndrome scale (PASS), combined somatopathy, the time of protective constraint, modified electraconvulsive therapy (MECT), using two or more antipsychotics drugs, using antibiotics and side effects of drugs (P<0.05). However, there were no statistical differences in gender, age classes, the course of disease, frequency of hospitalization and seasonal incidence of hospital infection (P>0.05). The results of multivariate analysis showed that hospital stay, positive symptom score, negative symptom score, the time of protective constraint, MECT, using two or more antipsychotics drugs and side effects of drugs were the main risk factors for nosocomial infection of inpatients with psychopathy (P<0.05). ConclusionBased on the different traits and treatments of acute and serious schizophrenia, a screening table of infections should be set. For the high risk group of nosocomial infection, effective measures should be taken to prevent and control the nosocomial infection of patients with schizophrenia.
ObjectiveTo analyze the risk factors of acute pancreatitis (AP) associated with hepatic dysfunction. MethodsWe collected the clinical data of AP patients from June 2012 to December 2014. According to the hepatic function, patients were divided into normal or mildly abnormal group (A), moderately abnormal hepatic function group (group B) and hepatic failure group (group C). We comparatively analyzed the relationship of abnormal hepatic function with causes (biliary, alcoholic, hypertriglyceridemia, and the others), age, gender, abdominal CT findings, laboratory test results, Ranson scores and the severity of acute pancreatitis bedside index (BISAP). ResultsA total of 117 AP patients were included in the study, including 75 males and 42 females aged from 28 to 71 years with the mean age of (53.21±1.35) years. There were 73 patients with mild AP (MAP), 28 with moderately severe AP (MSAP) and 16 with severe AP (SAP). There were 64 patients in group A, 37 in group B, and 16 in group C, in whom 73 patients were with hepatic dysfunction. The ratio of SAP and MSAP in group C was 75.0%, and MAP was 25.0%. There were 52 patients with bilious AP, 39 with alcoholic AP, 19 with hypertriacylglycerolemia AP, and 7 with others; the difference in causes among the three groups were not significant (P > 0.05). The differences in serum amylase, prothrombin time, white blood cells count, serum creatinine, triglycerides, total cholesterol, hemoglobin, and blood urea nitrogen among the three groups were not significant (P > 0.05). ConclusionsAP associated with hepatic dysfunction or failure may be caused by a various of factors. Whether the changes of serum amylase, prothrombin time, white blood cell count, serum creatinine, triglycerides, total cholesterol, hemoglobin, blood urea nitrogen, and BISAP scores can be the indexes of the judgment of AP with hepatic dysfunction needs more researches. Proper assessment of the related risk factors helps to prevent serious hepatic dysfunction or even failure.
Objective To evaluate the relevant factors affecting prognosis of traumatic optic neuropathy. Methods Sixty-nine patients with traumatic optic neuropathy were enrolled. Multiple variable analysis was done to filter the risk factors to prognosis in traumatic optic neuropathy. Results At 3 months or more of followup,no light perception was found in 32 cases (46.4%); visual acuity were increased by≥1 lines in 33 cases (47.8%). The outcome of visual acuity was poorer in patients with the following conditions:no light perception after trauma （P=0.0031）, loss of consciousness （P=0.0262）, no pretreated common-dosage corticosteroids （P=0.0184）, and absence of VEP （P=0.0001）. Conclusion The initial visual acuity of no light perception, loss of consciousness, and no pretreated common-dosage corticosteroids were the risk factors to prognosis in traumatic optic neuropathy,and result of VEP was an effective prognosis indicator in traumatic optic neuropathy.

The pathogenesis of diabetic retinopathy (DR) is complex and there are many related risk factors. It is related to the course of diabetes, blood glucose, blood pressure, and blood lipids, among which the course of disease and hyperglycemia are recognized main risk factors. In addition, other factors which include heredity, gender, age, obesity, pregnancy, insulin use, can also affect the occurrence and development of DR, but there is no unified conclusion about its correlation. A comprehensive understanding of the risk factors that affect DR can provide new ideas for the prevention, diagnosis, treatment, and intervention of DR.
Non-arteritic anterior ischemic optic neuropathy (NAION) is one of the most common acute optic neuropathy in adult characterized with impaired visual acuity and visual fields. The pathogenesis of NAION mostly result from the interactions between the systemic risk factors (such as diabetes mellitus, night hypotension, hereditary) and the local ocular risk factors (such as small optic disc and vitreo-papillary traction). A fully promoted diagnosis and treatment of NAION are based on the higher levels of clinical evidence, as well as the comprehensive assessment of relationship between the systemic and ocular risk factors in the pathogenesis of NAION. Secondary optic neuropathy of NAION and the early diagnosis with effective treatment of the fellow eye would be highly emphasized.
ObjectiveTo investigate the prevalence and risk factors for chronic obstructive pulmonary disease (COPD) in Dayi County of Chengdu. MethodsRandomly cluster sampled residents between 40 and 70 years of age from two natural villages in the rural communities from February to December, 2010 were included in our study. We used questionnaire survey, physical examination and portable spirometry to collect data. Post-bronchodilator forced expiratory volume in 1 second/forced vital capacity of less than 70% was defined as the diagnostic criterion of COPD. Univariate analysis and logistic regression mode were used to define the risk factors. ResultsA total of 1 017 residents were enrolled in this survey, and 782 participants were valid for analysis, with a valid response rate of 76.89%. There were 330 males and 452 females, with an average age of (51.97±8.17) years old. The overall prevalence of COPD was 10.61%. After population standardization, the prevalence rate was 12.37%, and the overall prevalence increased with increment of age. The prevalence in male (13.33%) was higher than that in female (8.62%) with significant difference (P<0.01) and the prevalence increased with age. Univariate analysis showed that sex, age, education level, smoking and amount of smoking (pack-years) were the risk factors for COPD with significant difference. Logistic regression analysis showed that age, amount of smoking (pack-years) were the main risk factors for COPD. ConclusionCOPD is highly prevalent in Dayi County of Chengdu and it is important to prevent COPD by controlling smoking and improving education level.
Objective To observe the incidence of hypotony and its risk factors in the early stage after 23-gauge sutureless microincisional vitrectomy. Methods A retrospective case series. Seventy patients (70 eyes) who had undergone 23-gauge sutureless microincisional vitrectomy were enrolled. There were 41 phakic eyes, 29 eyes with intraocular lens; 68 eyes with a single surgical procedure and 2 eyes with a second surgical procedure; 34 eyes with BSS tamponade and 36 with gas tamponade. Intraocular pressure (IOP) was measured by non-contact tonometry. Hypotony was defined as an IOP of 5 mm Hg (1 mm Hg=0.133 kPa ) or less. The incidence of hypotony and other complications at postoperative day 1, 3 and 7 were observed. The influence of age, sex, side of operation, type of tamponade, status of lens, surgical time on postoperative hypotony was analyzed. Results Hypotony was found in 8 eyes (11.4%) on postoperative day 1 and recovered spontaneously on postoperative day 3. There were no significant differences comparing age (t=1.12), sex (chi;2=2.23) and side of operation (chi;2=2.01) between patients with hypotony and those without it. The patients with hypotony suffered longer surgical time than that of those without hypotony (chi;2=5.48,P＜0.05). The incidence of hypotony in eyes with gas tamponade was significantly lower than that in eyes with BSS tamponade (chi;2=5.48,P＜0.05). The incidence of hypotony in eyes with phakic eyes was lower than that in eyes with intraocular lens (chi;2=4.20,P＜0.05). Hypotony was encountered in the 2 re-operated eyes. Choriodal folds were encountered in 2 eyes, but there was no other complication in other eyes. Conclusions A transient hypotony occurs commonly in first 3 days after 23-gauge sutureless microincisional vitrectomy. Hypotony was significantly influenced by type of tamponade, reoperation and intraoperative lens status.
