Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Objective:To explore the relationship between red meat intake level and the incidence of stroke in Chinese adults.Methods:The baseline data were from China Chronic Disease Surveillance Project conducted in 60 surveillance sites in 11 provinces in China in 2010. A total of 27 762 subjects with complete data in baseline survey were included in the cohort follow-up from 2016 to 2017. Multivariate nutrient-density cox proportional hazards regression model was used to analyze the association between red meat intake level and the incidence of stroke. Subgroup analysis were performed based on baseline characteristics. Sensitivity analysis was performed by using standard multivariate model, energy partition model and nutrient residual model.Results:In the 26 187 subjects, 1 259 stroke cases, including 1 074 ischemic stroke cases, occurred during an average of 6.0 years of follow-up, the incidence density was 815.0/100 000 person-years for stroke and 692.0/100 000 person-years for ischemic stroke. In models using the multivariate nutrient-density model of energy adjustment, compared with quintile group, red meat intake in quintile 2 group showed no significant association with stroke [hazard ratio ( HR)=1.07, 95% CI: 0.87-1.32] and ischemic stroke ( HR=1.03, 95% CI: 0.80-1.32) and in group of quintile 3-5, the red meat intake related risk for stroke increased by 23% ( HR=1.23, 95% CI: 1.00-1.51), 27% ( HR=1.27, 95% CI: 1.03-1.58) and 32% ( HR=1.32, 95% CI: 1.06-1.64), respectively, while the risk for ischemic stroke increased by 32% ( HR=1.32, 95% CI: 1.04-1.68), 35% ( HR=1.35, 95% CI: 1.05-1.73) and 38% ( HR=1.38, 95% CI: 1.07-1.79), respectively. Subgroup analysis revealed that blood pressure had modification effect on the association between red meat intake and incidence of stroke (interaction P=0.037). The sensitivity analysis showed no changes. Conclusions:These findings suggest that higher intake of red meat is significantly associated with an increased risk for stroke and ischemic stroke. It is necessary to take red meat intake level as one of the important indicators of stroke prevention and control.

Objective To explore the clinical efficacy of biofeedback electrical stimulation plus pelvic floor muscle training (PFMT) in the treatment of stress urinary incontinence (SUI) after total hysterectomy.Methods The research objects who underwent total hysterectomy and complicated SUI were selected from January 2014 to December 2017 in our hospital.They were randomly divided into two groups:the study group (n =55) received biofeedback electrical stimulation plus PFMT treatment,while the control group (n=55) received PFMT treatment only.To record and compare the efficacy related indicators of the two groups.Results The indexes and scores of 3/6 months in the two groups were significantly improvedafter treatment.After 3 months the treatment,the study group had less leakage of urine [(4.3 ± 1.2)g vs (5.7 ± 1.9) g],better recovery of muscle strength of Ⅰ/Ⅱ muscle fibers [(3.5 ± 0.9) grade vs (2.8 ± 1.1) grade &(3.7 ± 0.6) grade vs (3.2 ± 1.2) grade],and better score of international consultation on incontinence questionnaire-short form (ICI-Q-SF) questionnaire [(2.7 ± 1.4) vs (4.5 ± 2.2)] compared with the control group,with statistically significant difference (P ≤ 0.05).After 6 months treatment,compared with the contiol group,the study group had less leakage of urine pad test [(1.4 ± 0.7) g vs (2.6 ± 1.1) g],better recovery of muscle strength of type Ⅰ/Ⅱ muscle fiber [(4.2 ±0.8) grade vs (3.5 ± 1.1)grade & (4.7 ±0.5) grade vs (4.0 ±0.9)grade],and better ICI-Q-SF score [(2.7 ± 1.4) vs (4.5 ±2.2)] (P ≤0.05).Conclusions Compared with using the PFMT alone,biofeedback electrical stimulation plus PFMT treatment had less leakage,better pelvic floor muscle strength and better subjective symptoms.

Objective To investigate the expression levels and clinical significances of ubiquitin-like with PHD and ring finger domains 1 (UHRF1) and P53 in colon carcinoma.Methods The expressions of UHRF1 and P53 in 70 colon cancer tissues and 30 normal colon ones were detected by means of immunohistochemistry to analyze the correlation of these two proteins in the occurrence and development of colon carcinoma,and the relationship between their expressions and clinico-pathological factors as well as prognosis was discussed.Results The expression levels of UHRF1 and P53 in cancer tissues were significantly higher than those of cancer-adjacent tissues (87.1％ vs.56.7％,x2 =11.366,P =0.001;64.3％ vs.6.7％,x2 =27.988,P =0.000) and showed a positive correlation between the two proteins (r =0.248,P =0.038).Both UHRF1 and P53 were associated with TNM stages (x2 =4.426,P =0.049;x2 =6.000,P =0.016) and the depth of invasion (x2 =12.553,P =0.002;x2 =4.904,P =0.036).However,they were irrelevant with the age (x2 =0.473,P=0.494;x2 =0.090,P=0.799) and gender (x2 =2.297,P=0.166;x2 =0.512,P=0.617) of patients,as well as the size (x2 =0.638,P =0.481;x2 =2.392,P =0.215) and histological grading of tumors (x2 =2.088,P =0.352;0.303,P =0.859).Kaplan-Meier analysis showed that the median survival time of patients with UHRF1,P53 positive expression was 21.83 months that was lower than patients with UHRF1 positive expression of 24.49 months (Z =-0.624,P =0.533).Both former of which was distinctly lower than that of negative ones of 37.33 months (Z =-2.856,P =0.004;Z =-2.694,P =0.007).Conclusion Both UHRF1 and P53 are highly expressed in colon cancer tissues,which imply that UHRF1 and P53 may be strongly related with colon cancer development and can be a predictor for colon cancer prognosis.

Objective:To research the imumunological effect of dendritic cell transfected by recombinant plasmid of ΔNp73αon breast cancer.Methods:Cultivate dendritic cells by cytokines( GM-CSF,IL-4,TNF-α) from human umbilical cord blood in vitro, CD1a,CD83 were detected by flow cytometry.Recombinant plasmid pcDNA-HA/ΔNp73αwas used to transfected DCs,the transfection was detected by Western blot.Transfected DCs cocultivate with T cell induce specific cytotoxic lymphocytes( CTL).Proliferation ability of T cell was detected by MTT methods.IFN-γin the culture supernatant of the transfected DCs were detected by ELISA.The killing effect on breast cancer MDA-MB-231 was detected by LDH method.Results:The expression of CD1a(56%),CD83(74%)in mature DC was higher than immature DC(CD1a 19%,CD83 13%)(P<0.01).ΔNp73αtransfected group had a special band.The killing effect of specific CTL induced byΔNp73α-DC and T cells cocultivation on breast cancer cell MDA-MB-231 was statistic stronger than DC group(P<0.05),the proliferation of T cell and secretion level of IFN-γcompared with DC and pcDNA group were statistically significant(P<0.01).Conclusion:The CTL induced byΔNp73αtransfected DC vaccine has significant effect on killing breast cancer.

OBJECTIVE:To investigate clinical efficacy and adverse reactions(ADRs)of 4 kinds of the second-generation anti-psychotic drugs in the treatment of acute phase of schizophrenia. METHODS:159 patients with schizophrenia were randomly divid-ed into risperidone group(40 cases),olanzapine group(40 cases),aripiprazole group(39 cases)and ziprasidone group(40 cas-es). All groups were given routine dosage of relevant medicine by routine usage for 6 weeks. Mental status of patients were mea-sured by PANSS before treatment and after 2,4 and 6 weeks of treatment. At the same time,blood glucose,blood lipid,prolac-tion and other metabolic and biological indicators were all detected. RSESE,BARS and UKU were adopted to evaluate ADR. RE-SULTS:A total of 100 patients completed the study. Compared with aripiprazole group and ziprasidone group,risperidone and olan-zapine inhibited symptom more rapidly,with statistical significance (P<0.05). After treatment,body mass index and abdominal circumference of olanzapine group were significantly higher than those of other 3 groups,with statistical significance (P<0.05). Low density lipoprotein of olanzapine group was increased significantly,there was statistical significance compared to ziprasidone group and aripiprazole group(P<0.05). Prolactin level of risperidone group was significantly higher than those of other 3 groups, while that of aripiprazole group was significantly lower than those of other 3 groups,with statistical significance(P<0.05). ADRs of 4 drugs were mild or moderate,most of whom could be alleviated by symptomatic treatment. CONCLUSIONS:In the treatment of acute phase schizophrenia,4 drugs of the second-generation have similar curative effect in symptoms control,among which ris-peridone and olanzapine inhibit positive symptom more rapidly while more ADRs that related to lipid and glucose metabolism and prolactin also show. Aripiprazole and ziprasidone induce less ADRs relatively,and patients show better tolerability. Physicians should consider all kinds of factors in drugs selection,and make individualized treatment plan.
