Objective To explore the clinical efficacy and safety of cyclosporin A combined with glucocorti-costeroid in the treatment of juvenile uveitis.Methods 66 juvenile uveitis patients(93 eyes)were selected.Accord-ing to the conditions,the patients were treated by oral administration of cyclosporin A,2-5mg·kg -1 ·d -1 ,twice per day,combined with prednisone,0.5-1mg·kg -1 ·d -1 ,taken in the morning.After 4-6 months treatment,the inflam-mation control and visual acuity improvement were observed,and before and after treatment liver and kidney function, blood glucose,blood pressure,white blood cell counts were checked.Adverse reactions in patients were recorded with regular follow-up.Results After 4-6 months treatment,heal inflammation 78 eyes,accounted for 83.87%;improved 9 eyes,accounted for 9.68%;no respond in 6 eyes,accounted for 6.45%;the total effective rate was 93.55%.Visual acuity was obviously improved in 50 eyes,improved in 27 eyes and no response in 16 eyes;the total effective rate was 82.79%;56 eyes were removed from residual standard.In the stage of therapy,6 patients had liver and kidney dys-function,6 patients had blood abnormalities,and 3 patients had low blood sugar,all were controlled by symptomatic treatment in the normal range,and no systemic progression.Conclusion Cyclosporin A combined with glucocortico-steroid applied in juvenile uveitis improved the results with obvious clinical effect and fewer systemic side effect.

Objective To assess the association between exposure to prenatal outdoor air pollution and preterm birth to provide evidence in setting up programs for prevention on premature birth.Methods Case-control studies regarding association between pregnant exposure to outdoor air pollution and preterm birth were collected.Data were analyzed with Stata 12.0.Results Ten articles including 48 556 cases and 548 495 controls were qualified for inclusion.Results from Meta-analyses showed pooled ORs for exposure to NO2,PM10,CO,PM2.5,and NO during the entire pregnancy were 0.960 (95％CI:0.935-0.985),1.068 (95％CI:1.035-1.103),1.122 (95％CI:1.078-1.168),1.110 (95％ CI:1.043-1.181) and 0.994 (95％ CI:0.973-1.016).Association between air pollution and preterm birth varied with the periods of exposure.Pooled ORs for NO2,PM10 and SO2 exposure during the first trimester were 1.117 (95％CI:1.052-1.186),0.968 (95％CI:0.812-1.153) and 1.258 (95％CI:0.758-2.089).Pooled ORs for NO2,PM10,SO2 exposure during the second trimester were 1.000 (95％ CI:0.982-1.019),1.127 (95％ CI:0.896-1.416) and 0.977 (95％CI:0.711-1.342).Pooled ORs for NO2,PM10,SO2 exposure during the third trimester were 1.006 (95％CI:1.002-1.010),1.053 (95％CI:0.973-1.139) and 1.003 (95％CI:1.000-1.006).Conclusion Exposures to PM10,CO and PM2.5 during the entire pregnancy,to NO2 during the first trimester,or to NO2 and SO2 during the third trimester were associated with preterm births.

Objective This study aimed to apply quantile regression to study Hanzhong rural residents health survey data,explore the local distribution characteristics of health-related quality of life (HRQOL) and influencing factors and present the value of quantile regression applying in analysis of HRQOL.Methods In this cross-sectional population-based study,we evaluated the HRQOL of 2 737 subjects through filling Short-Form Health Survey (SF-36).Quantile regression model was used to compare MCS and PCS scores and evaluate the associated factors.Results With different quantiles MCS and PCS score,the associated factors and influence degree were different.In general,the influences of marital status,educational level,physical activity,history of disease and HRQOL in the part of the percentile scores were significant.Conclusion Analysis of the distribution of HRQOL of rural residents in Hanzhong and influencing factors would benefit the improvement of HRQOL of local residents.

Objective:To explore the epidemiology, clinical features and prognosis of pseudorabies virus (PRV) infection in human.Methods:A case of human PRV encephalitis combined with acute retinal necrosis (ARN) in the First Affiliated Hospital of Zhengzhou University in May 2020 was reported. The epidemiology, clinical features, neuroimaging, cerebrospinal fluid (CSF), next-generation sequencing (NGS), treatment and prognosis of human PRV infection were summarized and analyzed with the previous published data.Results:The present case was a 38-year-old man who developed high fever, headache, cognitive decline, recurrent epileptic seizures after butchering a pig. Brain magnetic resonance imaging showed lesions in the insular lobes, temporal lobes, cingulate gyrus, frontal lobes, basal ganglia and hippocampus, with more significant signals on the left side. Afterwards, bilateral ARN occurred and resulted in his blindness. PRV DNA was detected from the aqueous humor. By literature review, a total of 20 cases (including this case) were analyzed. Most patients (95%, 19/20) had the history of direct contact with swine. The median incubation period was 7 days. The infection normally caused encephalitis (95%, 19/20), some cases with endophthalmitis (60%, 12/20). Based on the neuroimaging of the 19 patients, the lesions in neuroimaging were mainly in limbic system, especially in insular (17/19) and temporal lobes (17/19). The basal ganglia was often involved (9/19).The PRV-DNA was detected by NGS in CSF or intraocular fluid. Antiviral drugs and adjuvant treatment, including immunoglobulin and/or corticoid therapy, were effective to only few cases. Most patients (90%, 18/20) had the sequelae of severe impairment of daily living (modified Rankin Scale scores≥3).Conclusions:The cardinal clinical characteristics of human PRV infection are progressive panencephalitis and endophthalmitis, with an unfavorable outcome. The history of exposure to sick swine and typical neuroimaging suggest PRV infection. NGS of CSF and/or intraocular fluid is the dependable diagnostic method.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.
