Objective To evaluate multichannel functional electrical stimulation (FES) on motor and balance function of lower limbs in adolescent with cerebral palsy. Methods From January, 2014 to June, 2015, 20 adolescents with cerebral palsy were randomly divided into FES group (n=10) and control group (n=10). Both groups received routine exercise therapy. FES group received active and passive FES treadmill based on normal walking pattern. The Fugl-Meyer Assessment (FMA) was used to evaluate the motor function of lower limbs;the Berg Balance Scale (BBS) was used to assess the balance function, and the Gross Motor Function Measure (GMFM) was used to test the gross motor function. Results The scores of FMA, BBS and GMFM significantly improved 30 days after treatment (F>223.749, P<0.001), and the scores were higher in the FES group than in the control group (t>2.706, P<0.05). Conclusion FES treatment can improve the motor and the balance function of lower limbs in adolescents with cerebral palsy.

Objective To study the effect of Chinese wild rice diet on lipid metabolism in rats. Method Forty four male SD rats were divided into 4 groups:control group, high lipid group, white rice-flour group and Chinese wild rice group. All groups were given different experimental diets for 8 w and body weights, serum TC, TG, HDL-C, high sensitive C-reactive protein (hs-CRP), TNF-? and IL-6 were measured. Results The hyperlipidemic rat model was successfully induced. When compared with high lipid group and white rice-flour diet group, serum TG and TC contents were significantly decreased, and HDL-C significantly increased in the Chinese wild rice group. Moreover, Chinese wild rice group had lower contents of serum hs-CRP and TNF-? than those in high lipid group and white rice-flour group, but no effect on serum IL-6. Conclusion Chinese wild rice could improve lipid metabolism and low-grade inflammation of hyperlipidemic rats induced by high lipid diet.

Objective To investigate the clinical significance of peripheral blood Th17 cells and their cytokines in the patients with tongue squamous cell carcinoma.Methods Sixty-six cases of tongue squamous cell carcinoma in our hospital from January 2013 to January 2016 served as the research subjects and contemporaneous 42 volunteers undergoing healthy physical examination were selected as the control group.Peripheral blood was collected in all subjects.The proportion of peripheral blood Th17 cells was detected by flow cytometry.The IL-17,TGF-β and IL-6 cytokine levels were detected by ELISA.Results The proportion of peripheral blood Th17 cells,IL-17,TGF-β and IL-6 in the observation group and the control group were (1.46±0.41)% vs.(0.31±0.12)%,(123.36±21.20)pg/mL vs.(20.76±8.95)pg/mL,(215.80±21.52)pg/mL vs.(26.90±10.41)pg/mL,(17.32±8.02)pg/mL vs.(5.85±1.49)pg/mL respectively,the differences were statistically significant(P<0.05).The proportion of peripheral blood Th17 cells,IL-17,TGF-β and IL-6 levels were increased with the increase of tongue squamous cell carcinoma clinical stage (P<0.01).The TGF-β level was positively correlated with the IL-17 level (r=0.626,P=0.021),the IL-6 level was positively correlated with the proportion of Th17 cells and IL-17 (r=0.626,0.597,P=0.021,0.034).Conclusion The increase of Th17 cells and IL-17 expression plays an important role in the development and progression of tongue squamous cell carcinoma,Th17 cells and IL-17 cytokine can become the important target spots of anti-tumor therapy.

Aim To investigate the influence of intranasal delivery of calcitonin gene-related peptide(CGRP)on cerebral blood supply and expression of vascular endothelial growth factor(VEGF)following experimental subarachnoid hemorrhage(SAH).Methods Wistar rats were divided into normal control group,SAH group,intranasal normal saline(NS)+SAH group and intranasal CGRP+SAH group.SAH models were produced by double injection of autologous arterial blood into cisterna magna.CGRP and NS were given by intranasal perfusion.Dynamic observations of regional cerebral blood flow(rCBF)of cerebral cortex were made using a laser Doppler flowmeter probe.On the third day after the second cisternal injection,the expression of VEGF protein in cerebral cortex was observed by immunofluorescence method combined with laser confocal microscopic observation.Results Anatomic observation revealed that SAH models were successfully manufactured.In SAH and intranasal NS+SAH groups,a drastic and persistent drop in rCBF was noted during the observed periods.The decrease of rCBF in intranasal CGRP+SAH group was slighter as compared with that in SAH and intranasal NS+SAH groups.In SAH and intranasal NS+SAH groups,increased expression of VEGF protein in cerebral cortex was observed on the third day after second cisternal injection as compared with that in normal control group.The expression of VEGF in intranasal CGRP+SAH group was more obvious than that in intranasal NS+SAH group.Conclusion Intranasal delivery of CGRP improves cerebral blood supply and promotes angiogenesis by enhancing the expression of VEGF after SAH.

Objective To investigate the epidemiological and clinical characteristics of measles in patients of different age groups in Northeast China in 2014.Methods The clinical data of patients with measles in ten hospitals of infectious diseases in Northeast China from January 2014 to June 2014 were collected.Patients were divided into <16 age group and ≥16 age group, and the epidemiology , clinical characteristics, treatment and prognosis of all patients were retrospectively reviewed .SPSS 17.0 was used for data analysis.Results There were 1 401 patients with measles, in which 402 were <16-year old, and 999 were ≥16-year old.Clinical manifestations were mainly maculopapule (100.0%), fever (84.58%), cough (85.80%), Koplik’ s spot (73.23%), pharyngeal hyperemia (71.23%), diarrhea (43.97%), expectoration (40.97%), tears (39.40%) and runny nose (30.55%).The incidences of Koplik’s spot, sputum, pharyngeal hyperemia and diarrhea in <16 age group were lower than those in ≥16 age group (χ2 =8.364, 29.768, 10.953 and 6.701, P<0.05 or <0.01); while the incidence of runny nose was higher than that in ≥16 age group (χ2 =6.703, P<0.05).Abnormalities were found in blood routine examination, C-reactive protein (CRP), liver and kidney function, serum electrolyte levels, myocardial enzymes, and so on.Increasing in WBC, PLT and creatine kinase isoenzyme (CKMB), and decreasing in WBC were observed in 38(9.45%), 122(30.35%), 279(69.40%) and 105(26.12%), patients in <16 age group, which were higher than those in ≥16 age group [45(4.5%), 14(1.40%), 347(34.73%) and 202(20.22%)], and the differences were of statistical significance (χ2 =12.593, 274.033, 139.385 and 5.830, P<0.05 or P<0.01).Increasing in alanine aminotransferase (ALT), CRP, total bilirubin level (TBil), creatine kinase (CK), and decreasing in albumin (Alb), K+, Na+, Cl-were observed in 70(17.41%), 7(1.74%), 38(9.45%), 7(1.74%), and 214(53.23%), 59(14.68%), 45(11.19%), 94(23.38%) patients in <16 age group, which were lower than those in ≥16 age group [668(66.87%), 89(8.91%), 277(27.73%), 714(71.47), and 268(26.83%), 339(33.93%), 642(64.26%), 450 (45.05%)], and the differences were of statistical significance (χ2 =281.230, 23.073, 50.687, 159.740, and 14.674,114.286, 44.268, 271.546, P<0.01).Laryngitis and pneumonia were the most common complications.The incidence of laryngitis in <16 age group was 12.69% (51/402), which was higher than that in ≥16 years group (93/999, 9.31%,χ2 =3.545, P<0.05);while the incidence of spot shadows demonstrated by X-ray in <16 years group ( 72.89%, 121/166 ) was higher than that in ≥16 years group (265/445, 59.55%,χ2 =9.249, P<0.01).Conclusions There are differences in clinical features of measles in patients between <16 age group and ≥16 age group.Basic immunization in children and revaccination in adults should be enhanced to control the epidemics of measles .

Objective:To investigate the characteristics of gut microbiota in children with sepsis and the effects of probiotic intervention.Methods:Thirty-four children with sepsis admitted to the Pediatric Intensive Care Unit of Henan Provincial People′s Hospital were enrolled in this prospective study from May 2019 to July 2020. They were randomly divided into two groups and received conventional treatment (conventional treatment group, n=17) and conventional treatment combined with probiotics (probiotics group, n=17), respectively. Twenty healthy children were selected as healthy control group. The baseline characteristics and sequential organ failure assessment (SOFA) score of all children with sepsis were recorded within 24 h after recruitment. Stool samples were collected 5-7 d after recruitment. High-throughput 16S rRNA gene sequencing was used to detect gut microbiota. Bioinformatic analysis and predictive functional profiling of microbial communities were performed to analyze the differences between groups. Results:The α-diversity and β-diversity indexes showed compared with the healthy control group, the two sepsis groups had lower abundance of gut microbiota, but greater individual differences in bacteria structure. These indexes were improved significantly following probiotic intervention ( P<0.05). At the level of phylum, the proportions of Bacteroidota and Actinobacteriota in the conventional treatment group were the lowest among the three groups, while the proportion of Proteobacteria increased significantly ( P<0.05). At the level of genus, Enterocoddus was the predominant bacterium in the conventional treatment group, while the abundance of Bifidobacterium, Faecalibacterium, Erysipelotrichaceae and Rumimococcus- torques in the probiotics group showed an upward trend ( P<0.05). Differences in the abundance of metabolic pathways, including mitochondrial synthesis, exosomes, mRNA transcription and degradation and cysteine metabolism, could be found between the two sepsis groups. Conclusions:This study revealed that children with sepsis exhibit a dysbiotic microbial community with reduced microbial diversity, declined structural stability, decreased abundance of Bacteroidota and enrichment of Proteobacteria. Probiotic supplementation could elevate the percentage of beneficial symbiotic bacteria and reduce the number of pathogenic bacteria. The differential metabolic pathways might be associated with the mechanism of probiotics in practice.

At present, immunotherapy is in full swing in the treatment of non-small cell lung cancer, melanoma, bladder cancer and other tumor species, and its treatment methods are also diverse, including tumor vaccine treatment, adoptive T cell therapy, immune checkpoint inhibitor treatment, etc, but current immunotherapy for colorectal cancer mainly focuses on immune checkpoint inhibitors (PD-1/PD-L1 and CTLA-4 inhibitors). Since PD-1/PD-L1 inhibitors have shown amazing efficacy in patients with dMMR/MSI-H advanced colorectal cancer, immune checkpoint inhibitors have gained more and more attention in the field of colorectal cancer, and the treatment options have gradually shifted from late line treatment to first-line treatment or neoadjuvant therapy, and have achieved success. This paper summarizes the research progress of immune checkpoint therapy on colorectal cancer.

Objective:To investigate whether the synonymous variation of the ATP-binding cassette transporter A3 (ABCA3) gene may increase the risk of respiratory distress syndrome (RDS) in Mongolian and Han newborns in Inner Mongolia.Methods:From January 2018 to June 2019, the children of Mongolian and Han nationality who were hospitalized in the Department of Neonatal Pediatrics, affiliated Hospital of Inner Mongolia Medical University and the control group were sequenced by ABCA3 exon gene to analyze whether there was synonymous mutation in ABCA3 gene.Results:A total of 101 children with RDS were enrolled, including 37 children with Mongolian and 64 with Han children. There were 113 patients in the control group, including 45 Mongolian children and 68 Han children. Children with Mongolian and Han nationality RDS and control group can detect multiple synonymous mutation sites, such as: F353F, P585P, A227A, V150V, L982L, A928A, S1372S, P1653P, E1618E, and A1027A, etc, among them, four synonymous variants of p.A227A, p.F353F, p.P585P and p.S1372S are common synonymous mutants. In both Mongolian and Han nationality, the frequency of ABCA3 gene synonymous mutation in RDS group was significantly higher than that in control group (Mongolian: χ2=9.402, P=0.002; Han: χ2=9.348, P=0.002 ). The mutation rates of F353F and P585P in Mongolian and Han children with RDS were higher than those in the control group, and the difference was statistically significant(Mongolian F353F: χ2=5.270, P=0.022; Han F353F: χ2=5.532, P=0.019.Mongolian P585P: χ2=4.711, P=0.030; Han P585P: χ2=4.480, P=0.034). Conclusions:The synonymous variation of ABCA3 gene may increase the risk of RDS in Mongolian and Han newborns in Inner Mongolia, and F353F and P585P may be one of the susceptible genes of RDS in Mongolian and Han newborns in Inner Mongolia.

Objective:To evaluate the effect of gender factor on the potency of remimazolam inhibiting responses to laryngeal mask airway (LMA) insertion.Methods:Patients of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 18-60 yr, with body mass index of 18-28 kg/m 2, requiring LAM insertion, undergoing elective surgery, were divided into 2 groups according to the gender: male group (group M) and female group (group F). The dose of remimazolam was determined by using modified Dixon′s up-and-down method.Remimazolam 0.3 mg/kg was injected intravenously in the first patient.When the patients lost consciousness, bispectral index value ≤60 or modified Observer′s Assessment of Alertness/Sedation score <1, sufentanil 0.3 μg/kg and rocuronium 0.6 mg/kg were injected intravenously, and the LMA was inserted 3 min later.The positive response to LMA insertion was defined as swallowing, biting LMA, bucking, body movement during insertion, or an increase in the maximum mean arterial pressure or the maximum heart rate >20% of the baseline value with 2 min after insertion.When the response to LMA insertion was positive or modified Observer′s Assessment of Alertness/Sedation score >1 after injection of remimazolam, the dose of remimazolam was increased in the next patient, otherwise the dose was decreased, and the difference between the two successive doses was 0.03 mg/kg.This process was repeated until the 7th turning point occurred.The median effective dose (ED 50) and 95% confidence interval (CI) of remimazolam inhibiting responses to LMA insertion were calculated by Probit. Results:A total of 29 cases in group F and 22 cases in group M completed the study.The ED 50 (95% CI) of remimazolam was 0.146 (0.106-0.175) mg/kg in group F. The ED 50 (95% CI) of remimazolam was 0.203 (0.131-0.237) mg/kg in group M. The ED 50 of remazolam was significantly higher in group M than in group F ( P<0.05). Conclusion:The potency of remimazolam inhibiting responses to LMA insertion is more effective in female patients than in male patients.
