Clinical characteristics of late-onset epileptic spasm / 中华实用儿科临床杂志

Objective:To analyze the clinical characteristics of late-onset epileptic spasm (LOS), thus providing basis for its early identification and treatment.Methods:Clinical data[electroencephalogram(EEG), imaging, treatment and prognosis]of LOS patient hospitalized in the Department of Pediatrics, the Second Affiliated Hospital of Xi′an Jiaotong University from January 2017 to June 2019 were retrospectively analyzed.Results:The age of onset of spasm in 35 children with LOS ranged from 18 months to 11 years old, with a median of 42 months.There were 21 cases of symptomatic LOS (60.0%) and 14 cases of cryptogenic LOS (40.0%). Epileptic spastic seizures, generalized seizures, partial seizures and myoclonic seizures as the first onset were reported in 13 cases (37.1%), 11 cases (31.4%), 10 cases (28.6%), and 1 case (2.9%), respectively.There were 15 cases (43.9%) of flexion type, 11 cases (30.4%) of extension type and 9 cases (25.7%) of mixed type.Spastic seizures can be presented as genera-lized or focal seizures.Among the 35 cases of LOS, 12 cases (34.3%) had normal EEG background, 18 cases (51.4%) had slow EEG background, and 5 cases (14.3%) had high EEG irregularity.Three cases were in accor-dance with Lennox-Gastaut syndrome and the other 32 cases were not in accordance with the defined epileptic syndrome.Eighteen cases were treated with antiepileptic drugs, and sodium channel blockers were added in 9 cases; 17 cases were treated with glucocorticoid.Eight cases did not have seizures at the last follow-up.There were 17 children with seizure reduction ≥ 50%, 3 cases with seizure reduction < 50%, and 7 cases with no reduction of seizure.Conclusions:LOS is mostly symptomatic and often associated with other types of seizures.Most of cases do not have high irregularity in the EEG, and the focal discharges are mainly in the temporal region or frontotemporal region, with refractory epilepsy mainly.The onset age, etiology and EEG characteristics of LOS differ from those of West syndrome, which should be detected and treated as soon as possible to improve the prognosis in pediatric patients.

Clinical and genetic characteristics of pyridoxine-dependent epilepsy / 西安交通大学学报(医学版)

【Objective】 To analyze the clinical features and gene mutation characteristics of four children with pyridoxine-dependent epilepsy (PDE) in order to provide evidence for early diagnosis of this rare disease. 【Methods】 The clinical data of four cases of PDE were collected from January 2016 to June 2019 in The Second Affiliated Hospital of Xi’an Jiaotong University. We collected data of the laboratory examination, electroencephalogram, and magnetic resonance imaging (MRI). Peripheral venous blood was collected from children and parents, genomic DNA was extracted from white blood cells, and primers were designed to amplify the aldehyde dehydrogenase 7 family member A1(ALDH7A1) on the long arm of chromosome 5 using PCR; exon and the junction of exon and intron were also amplified to determine whether there is a gene mutation. 【Results】 All the 4 cases had a full-term birth and no history of birth asphyxia. ① Clinical features: onset time from 8 days after birth to 6 months after birth. Type of seizure: 1 case with myoclonus onset, then converted to spasm; 1 case for generalized seizures; 2 cases for partial seizures, then converted to generalized seizures; 3 cases were prone to epileptic seizures; 1 case was significantly worse after infection; MRI: 3 cases showed no abnormalities, 1 case showed non-specific abnormalities; EEG: One case was fragmentary hypsarrhythmia, 3 cases of multifocal epileptiform discharge; Treatment: a small dose of vitamin B6 could control the seizure, 1 of them was controlled at a tiny dose, and 3 cases were controlled by a small dose. ② Genetic analysis results: There were 4 cases of ALDH7A1 gene mutation, of which 3 cases were known gene mutations and 1 case was new mutation. 【Conclusion】 PDE has an early onset, often in the neonatal or small infancy, is prone to epilepticus and has an increased severity after infection. There is no specificity in seizure type, EEG or MRI. The analysis of ALDH7A1 gene and vitamin B6 load test can help to confirm the diagnosis, small dose of Vitamin B6 can control the seizures so as to provide reference for the dose of vitamin B6. However, the number of cases is small, and a large sample size is still needed for verification.

Expression and correlation analysis of H19, MMP-2, MMP-9 in patients with recurrent spontaneous abortion / 中国医师杂志

Objective:To investigate the expression and correlation of H19, matrix metalloproteinase (MMP)-2 and MMP-9 in patients with recurrent spontaneous abortion (RSA).Methods:Human extravillous trophoblast cell line HTR-8 was cultured in vitro. Lentivirus was used to infect the HTR-8 cell line to over-express or knockdown the expression of H19. The concentrations of MMP-2 and MMP-9 protein in cell culture supernatant were detected by enzyme linked immunosorbent assay (ELISA). The expression levels of H19, MMP-2 and MMP-9 mRNA in villi of patients with RSA were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR). Spearman correlation analysis was used to understand the correlation between H19 and the expression levels of MMP-2 and MMP-9. Results:After overexpression of H19, the expression levels of MMP-2 and MMP-9 mRNA and protein concentration in Lv-ph19 group were significantly higher than those in Lv-vector group ( P<0.05); After interfering with the expression of H19, the expression levels of MMP-2 and MMP-9 mRNA and protein concentration in Lv-shH19 group were significantly lower than those in Lv-shcon control group ( P<0.05). The number of spontaneous abortions in patients with recurrent spontaneous abortion was significantly higher than that in the control group ( P<0.05). qRT-PCR showed that the expression levels of H19, MMP-2 and MMP-9 mRNA in villi of patients with RSA were significantly lower than those in the control group ( P<0.05). There was a positive correlation between H19 and the expression levels of MMP-2 and MMP-9 ( P<0.05). Conclusions:H19 regulates the expression of MMP-2 and MMP-9 of trophoblast during early pregnancy, and the abnormal expression of H19, MMP-2, and MMP-9 in human first-trimester villous tissues was related with the incidence of early miscarriage.

Significance of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio for predicting clinical outcomes in COVID-19

BackgroundThe epidemic of 2019 novel coronavirus (COVID-19) struck China in late December, 2019, resulting in about 200000 deaths all over the world. Numerous observational studies have suggested that the neutrophil-to-lymphocyte ratio (NLR) and lymphocyte proportion and the platelet-to-lymphocyte ratio (PLR) are inflammatory markers. Our study aimed to detect the role of NLR, PLR in predicting the prognosis of COVID-19. MethodsFour hundred and fifteen consecutive patients were enrolled in Shanghai Public Health Clinical Center affiliated to Fudan University, between 20 January and 11 April 2020 with confirmed COVID-19. Epidemiology, symptoms, signs, and laboratory examinations during the hospital stay were collected and compared between non-severe and severe patients. Statistical analysis was performed by SPSS 25.0 software. ResultsFour hundred and fifteen laboratory-confirmed COVID-19 patients were included in our study, among which 386 (93%) patients were not severe, and 27 (7%) were severe. The proportion of males in severe cases is higher than in non-severe cases (75.86% vs. 50.52%, P=0.008). The age between the two groups is different (p=0.022). Compared with non-severe patients, severe patients exhibited more comorbidities, including hypertension (48.28% vs. 19.43%, p<0.001), diabetes (20.69% vs. 6.99%, p=0.009), chronic obstructive pulmonary disease (51.72% vs. 6.22%, p<0.001), and fatty liver (37.93% vs. 15.8%, p=0.002), respectively. NLR and PLR showed significant difference (p<0.001). Diabetes (OR 0.28; 95% CI 15.824-187.186), fatty liver (OR 21.469; 95% CI 2.306-199.872), coronary heart disease (OR 18.157; 95% CI 2.085-158.083), NLR (OR 1.729; 95% CI 1.050-2.847) were significantly associated with severe cases with COVID-19. The NLR of patients in severe group had a 1.729-fold higher than that of no-severe group (OR 1.729; 95% CI 1.050-2.847, P=0.031). ConclusionsNLR is an independent risk factor of severe COVID-19 patients. PLR, NLR were significantly different between severe and non-severe patients, so assessment of NLR, PLR may help identify high risk cases with COVID-19.

Clinical Features of COVID-19 Related Liver Damage

BACKGROUNDA recent outbreak of SARS-CoV-2 infection occurs mainly in China, with rapidly increasing the number of cases (namely COVID-19). Abnormal liver functions are frequently present in these patients, here we aimed to clarify the clinical features of COVID-19-related liver damage to provide some references for the clinical treatment. METHODSIn this retrospective, single-center study, we included all confirmed COVID-19 cases in Shanghai Public Health Clinical Center from January 20 to January 31, 2020. The outcomes were followed up until February 19, 2020. A total of 148 cases were analyzed for clinical features, laboratory parameters (including liver function tests), medications and the length of stay. FINDINGSOf 148 confirmed SARS-CoV-2-infected patients, 49.3% were females and 50.7% were males. The median age was 50.5 years (interquartile range, 36-64). Patients had clinical manifestations of fever (70.1%), cough (45.3%), expectoration (26.7%) at admission. 75 patients (50.7%) showed abnormal liver functions at admission. Patients (n = 75) who had elevated liver function index were more likely to have a moderate-high degree fever (44% vs 27.4%; p = 0.035) and significantly present in male patients (62.67% vs 38.36%; p = 0.005). The numbers of CD4+ and CD8+ T cells were significantly lower in abnormal liver function group than those in normal liver function group. There was no statistical difference in prehospital medications between normal and abnormal liver function groups, while the utilization rate of lopinavir/ritonavir after admission was significantly higher in patients with emerging liver injury than that in patients with normal liver functions. Importantly, the emerging abnormal liver functions after admission caused a prolonged length of stay INTERPRETATIONSARS-CoV-2 may cause the liver function damage and the Lopinavir/ritonavir should be applied carefully for the treatment of COVID-19.

Application of the China-PAR risk prediction model for atherosclerotic cardiovascular disease in a rural northern Chinese population / 北京大学学报(医学版)

Objective:To validate five-year risk prediction models for atherosclerotic cardiovascular di-sease (ASCVD) in a contemporary rural Northern Chinese population.Methods: Totally 6 489 rural adults aged 40 to 79 years without clinical ASCVD were enrolled at baseline between June and August 2010, and followed up through January 2017.Expected prediction risk using the China-PAR (prediction for ASCVD risk in China) model was compared with the pooled cohort equations (PCE) reported in the American College of Cardiology / American Heart Association guideline.Kaplan-Meier analysis was used to obtain the observed ASCVD event (including nonfatal myocardial infarction, coronary heart disease death, nonfatal or fatal stroke) rate at 5 years, and the expected-observed ratios were calculated to eva-luate overestimation or underestimation in the cohort.The participants in the cohort were divided into 4 categories (<5.0%, 5.0%-7.4%, 7.5%-9.9%, and ≥10.0%) for comparisons based on ASCVD prediction risk.The models were assessed by discrimination C statistic, calibration χ2, and calibration charts and plots for illustration as well.Results: Over an average 5.82 years of follow-up in this validation cohort with 6 489 rural Chinese participants, 955 subjects developed a first ASCVD event.Recalibrated China-PAR model overestimated ASCVD events by 22.2% in men and 33.1% in women, while the overestimations were much higher for recalibrated PCE as 67.3% in men and 53.1% in women.Gender-specific China-PAR model had C statistics of 0.696 (95%CI, 0.669-0.723) for men and 0.709 (95%CI, 0.690-0.728) for women, which were similar to those of 0.702 (95%CI, 0.675-0.730) for men and 0.714 (95%CI, 0.695-0.733) for women in the PCE.Calibration χ2 values in China-PAR were 17.2 and 54.2 for men and women, respectively;however, the PCE showed poorer ca-libration (χ2=192.0 for men and χ2=181.2 for women).In addition, the calibration charts and plots illustrated good agreement between the observations and the predictions only in the China-PAR model, especially for men.Conclusion: In this validation cohort of rural Northern Chinese adults, the China-PAR model had better performance of five-year ASCVD risk prediction than the PCE, indicating that recalibrated China-PAR model might be an appropriate tool for risk assessment and primary prevention of ASCVD in China.

Relationship between glycemic control and visceral adiposity index among the patients with type 2 diabetes mellitus / 北京大学学报(医学版)

Objective: To explore the relationship between glycemic control and visceral adiposity index (VAI) among type 2 diabetes mellitus (T2DM) patients.Methods: A community-based epidemiological field study for patients with T2DM aged ≥ 40 years was conducted in China.Every participant underwent physical examinations, biochemical tests of fasting glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and so on, and a questionnaire, including anthropometric characteristics, lifestyle, disease history, family history, and medication use.Those participants with HbA1c ≥7.0% were classified as the poorly controlled in our analysis of relationship between glycemic control and VAI.Anthropometric characteristics, lifestyle, and biochemical indexes of the participants were compared among the groups of different VAI levels.Logistic models were applied in multiple analysis adjusting for possible confounders.Results: A total of 1 607 patients with T2DM were recruited in our analysis with a mean age of (59.4±8.1) years and an average T2DM duration of (7.0±6.4) years.Among them, 78.3% were on hypoglycemic therapy.The cutoff points of quartiles of VAI were calculated for the males and females, respectively.According to the ascending order of the quartiles of VAI, the participants were divided into four groups, i.e.Q1, Q2, Q3, and Q4.The poor glycemic control rate for these groups were 60.6%, 65.7%, 70.1%, and 71.0%, respectively (Trend χ2=12.20, P<0.001).After adjustment for age, gender, systolic blood pressure (SBP), diastolic blood pressure (DBP), LDL-C, smoking, cardio-cerebral vascular disease (CVD) history, hypoglycemic therapy, T2DM duration, and family history of diabetes, the Logistic regression models showed that the glycemic control rate was significantly associated with VAI levels among the patients with T2DM.Compared with the participants in group Q1, the ORs of poor glycemic control for those in groups Q2, Q3, and Q4 were 1.239 (95%CI 0.918 to 1.672), 1.513 (95%CI 1.117 to 2.050), and 1.535 (95%CI 1.128to 2.088), respectively (trend P=0.003).With each quartile increase in VAI, the OR of poor glycemic control was 1.162 (95%CI 1.054 to 1.282).Conclusion: The glycemic control among the patients with T2DM is significantly associated with VAI.High level of VAI is an indicator of poor glycemic control.

Study on AIDS-related knowledge and behavior between male-male in college students / 天津医药

Objective To understand the cognitive and behavioral characteristics of AIDS between male-male in college students, and to provide evidence for the prevention and control strategies. Methods Using cluster random sampling method, the questionnaire survey including basic situation, the perception of HIV/AIDS of male male actors, sexual behavior and condom use and HIV/AIDS counseling detection, was used to investigate in male students of 8 universities at Beijing fangshan distric. Results A total of 2444 male college students were surveyed, 138 cases with male-male behavior were detected, and the detection rate was 5.65％. The detection rate (18.31％) of the junior college students was statistically higher than that of first-year college students (4.28％) and sophomores (6.52％, P<0.017). The awareness rates of four relevant knowledge about HIV/AIDS for 138 students were 25.36％, 15.22％, 9.42％and 13.77％respectively. The 44.93％male-male in college students had first sexual intercourse were younger than 18 years old. The proportion of students with first time male-male behavior and age <18 years was higher in the first-year college students (58.9％) than that of sophomores and junior college students (30.77％, 26.92％). The incidence rate of bisexuality was 43.48％ in male-male behavior, and 73.91％ was polysexual partners. The correct usage rate of condom was 31.16％. AIDS counseling detection rate was 27.54％. Conclusion The detection rate is higher in students with male-male behavior, and the awareness rate of AIDS-related knowledge is lower. A variety of high risk sexual behaviors are prevalent, so it is necessary to strengthen HIV/AIDS education and HIV/AIDS related knowledge for college students.

Effect of large dose of Methylprednisolone on epilespy combined with electrical status epilepticus during sleep in children / 中华实用儿科临床杂志

Objective To investigate the clinical effect of large dosage of Methylprednisolone on epilespy combined with electrical status epilepticus during sleep(ESES) in children.Methods Forty-six epielpsy patients with ESES were treated with additive large dosage of Methylprednisolone.The seizures and video electroencephalogram discharges were observed before and after using Methylprednisolone.The Methylprednisolone effect in eliminating the methylprednisolone of ESES and controlling of clinical seizures and improving cognitive function were analyzed.Results Two cases were lost and 44 cases were included,male 30,female 14,the age at onset was (5.37 ±2.52) (2-9) years old.The duration of follow-up was (4.12 ± 2.00)(1-9) years old.The age at diagnosis of ESES was (8.17 ± 2.09) (4.0-12.5) years old.The efficacy of Methylprednisolone on seizures was 72.7％ (32/44 cases),while the efficacy of Methyl prednisolone on electroencephalograph (EEG) was 59.1％ (26/44 cases).For patients who were resistant to Levetiracetam or Clonazepam,Methylprednisolone was still effective.Intelligence quotient had no significant changes before and after treatment(P ＞ 0.05).The earlier onset age,the worse effect of Methylprednisolone.The efficacy of methylprednisolone for atypical benign epilepsy with cento-temporal spike(BECT) was higher than other syndromes.Conclusions Large dosage of Methyl prednisolone therapy for children with ESES,especially for those resistant to traditional or new antiepileptic drug for ESES,was effective and safe.The onset age and syndrome classification may have a certain value for prognosis and prediction of the effect of Methylprednisolone treatment.

Relationship between brachial-ankle pulse wave velocity and glycemic control of type 2 diabetes mellitus patients in Beijing community population / 北京大学学报(医学版)

Objective:To explore the correlation between glycemic control of type 2 diabetes mellitus (T2DM) patients and brachial-ankle pulse velocity (baPWV). Methods:A community-based cross-sec-tional study was conducted in Beijing, China. Every subject underwent physical examinations, glycated hemoglobin ( HbA1 c ) , blood lipid and baPWV measurements and completed a standardized question-naire. T2DM patients were divided into well controlled and poorly controlled groups according to HbA1c levels. The correlation between glycemic control of T2DM patients and baPWV was analyzed. Results:In this study, 1 341 subjects were recruited, including 733 T2DM patients and 608 non-diabetes sub-jects. Compared with non-diabetes subjects, abnormal baPWV ( baPWV≥1 700 cm/s) rate for T2DM patients was higher (40. 8% vs. 26. 8%, P<0. 001). With HbA1c<6. 5% or <7. 0% as the aim of glycemic control in T2DM patients, the abnormal baPWV rates for non-diabetes subjects, well controlled and poorly controlled T2DM patients were significantly different (non-diabetes vs. HbA1c<6. 5% T2DM vs. HbA1c≥6. 5% T2DM: 26. 8% vs. 32. 8% vs. 42. 6%, P <0. 001; non-diabetes vs. HbA1c <7. 0% T2DM vs. HbA1c≥7. 0% T2DM:26. 8% vs. 36. 1% vs. 43. 4%, P<0. 001). After being ad-justed for gender, age, smoking status, diabetes mellitus family history, T2DM duration, cardiovascular diseases ( CVD ) , waist hip ratio ( WHR ) , systolic blood pressure ( SBP ) , diastolic blood pressure ( DBP) , total triglycerides ( TG) , high density lipoprotein cholesterol ( HDL-C) , and low density lipo-protein cholesterol ( LDL-C ) , the Logistic regression models suggested that glycemic control status of T2DM patients was associated with abnormal baPWV. Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1 c <6 . 5% T2 DM patients and HbA1 c≥6 . 5% T2 DM patients were 0 . 927 (95%CI 0. 560-1. 537) and 1. 826 (95%CI 1. 287-2. 591). Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1c<7. 0% T2DM patients and HbA1c≥7. 0% T2DM patients were 1. 210 (95%CI 0. 808-1. 811) and 1. 898 (95%CI 1. 313-2. 745). Conclusion:The glycemic con-trol status of T2DM patients from communities is significantly associated with baPWV. Poor glycemic con-trol is a risk factor for abnormal baPWV. Keeping HbA1c under control might lower the risk of cardiovas-cular diseases in T2DM patients.

Effects of cyclooxygenase-2 selective inhibitor Celecoxib on the expression of P-glycoprotein in rat with status epilepticus / 中华实用儿科临床杂志

Objective To study the effect of cyclooxygenase-2 (COX-2)selective inhibitor Celecoxib on the expression of P-glycoprotein(P-gp)in the brain of rats with status epilepficus,in order to assess the therapeutic value of intractable epilepsy.Methods Sixty adult male SD rats were randomly divided into blank control group,the epilepsy model group and Celecoxib intervention group.The status epilepticus was induced in rats by injecting Lithium pilocarpine.Forty-eight rats were included in the experiment.There were 16 rats in each of the blank control group,epilepsy model group and Celecoxib intervention group,respectively.Immunohistochemical method and Western blot method were used to detect the expression of P-gp in experimental group in the frontal cortex and hippocampus.Results Immunohistochemistry result showed that the expression of P-gp was significantly higher in epilepsy model group than the blank control group,and the difference was statistically significant (P ＜ 0.01);The P-gp expression in the Celecoxib intervention group was lower than that in the epilepsy model group,and the difference was statistically significant (P ＜0.01).Western blot results suggested that the expression of P-gp could be found both in the frontal cortex and hippocampus in each group.Compared with the blank control group,the P-gp expression was significantly higher than that in the epilepsy model group,and the expression of the P-gp was lower after the Celecoxib intervention than that in the epilepsy model group,and the difference was statistically significant (P ＜ 0.05).Conclusions COX-2 inhibitor Celecoxib could decrease the expression of P-gp in brain tissue with status epilepticus,which may provide a new method for the treatment of intractable epilepsy.

ObjectiveTo explore the expression of CD3+ CD8+ human leukocyte antigen (HLA)-A2+T lymphocytes with specificity to the different hepatitis B virus (HBV) peptides in the peripheral blood mononuclear cells (PBMC)from the patients with hepatitis B associated hepatocellular carcinoma (HCC).MethodsThe HLA-A2+ PBMC from four patients with hepatitis B associated HCC were incubated with five HBV/HLA-A2 pentamers respectively,which were HBV sAg (FLLTRILTI),HBV sAg (GLSPTVWLSV),HBV sAg (WLSLLVPFV),HBV core (FLPSDFFPSV),and HBV pol (FLLSLGIHL),as well as anti-CD3-pacific blue and anti-CD8-fluorescein isothiocyanate (FITC).Then,HBV/HLA-A2-CD3-CD8 positive cells were detected by flow cytometry. The monoclonal HBV/HLA-A2-CD3-CD8+ cells were acquired by fluorescenceactivated cell sorter,and cultured and identified by flow cytometry.The anti-HBV specific T lymphocytes were then cultured with HepG2 (HLA-A2+ ) cells and the release of interferon γ (IFN-γ)were determined by enzyme-linked immunosorbent assay (ELISA),Res(a)ltsThe percentage of antiHBV T lymphoeytes with specificity to GLSPTVWLSV in total CD8+ T lymphoeytes from four patients with hepatitis B associated HCC was 1.44％±0.04％,which was higher than those to other four HBV antigen peptides (0.68％±0.08％ of FLLTRILTI,1.06％±0.09％ of FLPSDFFPSV,0.56％ ±0.04％ of FLLSLGIHL,and 0.46％ ±0.08％ of WLSLLVPFV) (t=0.001,P＜0.05).The two lines of monoclonal cell with specificity to GLSPTVWLSV both exhibited high level of IFN-γ expression after incubated with hepatic carcinoma cell line HepG2 (HLA-A2+)with HBV GLSPTVWLSV peptide.ConclusionsCD3+ CD8+ HLA-A2+ cells with specificity to the different HBV peptides exist in PBMC of patients with hepatitis B associated HCC.The expression level depends on HBV antigen peptide sequences and genomic sites.

Factors related to in-hospital deaths in patients co-infected with human immunodeficiency virus and tuberculosis / 中华传染病杂志

Objective To evaluate the risk factors associated with in-hospital death in patients co-infected with human immunodeficiency virus and Mycobacterium tuberculosis (HIV-TB). Methods A retrospective case-control study was performed in patients admitted to Shanghai Public Health Clinical Center from November 2004 to May 2009. Fifty-three HIV-TB patients who died during hospitalization were matched with 79 HIV-TB co-infected patients who survived during hospitalization.Clinical, demographic, and radiological characteristics of the two groups were compared by the retrospective case-control study method. Multivariate Logistic stepwise regression analysis was performed to explore the risk factors contributing to death in HIV-TB co-infected patients. Results Among the 459 co-infected patients, 53 (11.5%) cases died during hospitalization and 25 cases died during the first week in hospital. Sixty-four point two percent dead patients (34/53) died from tuberculosis. Several factors were associated with worse prognosis in the death group compared to the survival group, which included body weight≤50 kg (χ2 = 7.50), positive for acid-fast bacilli in sputum smear or culture exam (χ2= 4. 04, 14. 27), drug-resistant/multi-drug resistant Mycobacterium tuberculosis infection (χ2 =9.00,6.39), extra-pulmonary tuberculosis infection (χ2 =6.99), retreated tuberculosis (χ2 = 5. 92), non-standardized anti-tuberculosis treatment (χ2 = 12. 07), extensive pulmonary TB infection (lesions ≥50% of lung fields, χ2 = 20. 21), co-infection with fungi (χ2 =3.46), respiratory failure (χ2 = 4.27), non-pulmonary organ impairment (χ2 = 3.46), HIV infection longer than 5 years (χ2 = 7. 19), non-standardized highly active antiretroviral therary treatment (χ2 =5.16) and CD4+ T lymphocyte count ≤ 200 × 106/L (χ2= 12.99) (all P＜0. 05). Multivariate Logistic regression analysis showed that non-standardized anti-TB treatment, extensive pulmonary TB infection, multi-drug resistant TB infection and CD4+ T lymphocyte count ≤ 200 × 106/L were the major risk factors related to in-hospital mortality. Conclusions Non-standardized anti-TB treatment,extensive pulmonary TB infection, multi-drug resistant TB infection and CD4+ T lymphocyte count ≤200 × 106/L are the major risk factors related to in-hospital mortality in the patients co-infected with TB and HIV.

A study on the relationship between the polymorphisms in Interleukin 1 receptor accessory protein-like 2 and cognitive ability of the children in Qin-Ba mountainous region / 中华行为医学与脑科学杂志

Objective To explore the relationship between interleukin 1 receptor accessory protein-like 2 (IL1RAPL2) gene and cognitive abilities of children in Qin-Ba mountainous region. Methods Four tagged SNPs (rs5962434,rs5916817, rs3764765 and rs5962298 ) in IL1RAPL2 were selected, and then genotyped by PCR-SSCP method in a 320 children sample aged from six to fourteen years old. Results The results showed the rs5962434, rs5916817 ,rs3764765 and rs5962298 had no deviations from Hardy-Weinberg equilibrium (P＞0.05),and there were no significant statistical differences in the average psychometric scores of general cognitive ability(P=0.81,0.53,0.79,0.90) ,verbal comprehension (P=0.58,0.47,0.69,0.87 ) ,memory and concentration (P=0.69,0.35,0.76,0.90) among the compared genotype groups at each of the markers. Furthermore,the results also indicated that the four SNPs were not associated with perceptual organization in males and females respectively (P = 0.70,0.85,0.76,0.90,0.65,0.22,0.98,0.90 ). Conclusion The present work suggests that the human general cognitive ability, the three cognitive factors of C-WISC scale are not influenced manifestly by the genetic variations in IL1RAPL2.
