ABSTRACT

ObjectiveTo determine the epidemiological characteristics and risk factors of a norovirus GII.17 outbreak in Minhang District of Shanghai in 2018, and provide evidence for prevention and control measures of norovirus infection. MethodsDescriptive epidemiological analysis was performed. In addition, a retrospective cohort study was conducted to determine the risk factors. ResultsFrom May 30th to June 1st of 2018, a total of 132 cases (126 clinical cases and 6 confirmed cases) were documented,with an attack rate of 29.20%(132/452).All cases were children in a kindergarten, with the average age of 5 years and 43.9% being male. The cases were reported in all the classes, with no clustering by class or floor.The epidemic curve was characterized by a point source exposure, which was estimated to be probably between 7 AM on May 30thand 0:30 AM on May 31st. The retrospective cohort study showed that the attack rate significantly differed between the children who had taken and did not take the school lunch (RR=∞) on May 30th,and those who had taken and did not take seafood noodles (RR=4.11, 95%CI:1.09-15.55) (P<0.05). Among a total of 73 specimens, six specimens collected in child cases and one specimen in an asymptomatic chef tested positive for GII.17 type of norovirus. In addition, one retained food specimen of seafood noodles was positive for Aeromonas hydrophila. Viral shedding in the asymptomatic chef remained over 30 days. ConclusionThe outbreak was caused by seafood noodles contaminated by norovirus. It warrants enhancement in the regulation of food safety in canteens and regular examination of norovirus infection in catering industry employees.

ABSTRACT

Objective:To explore the profile and gene functional changes of gut microbiota (GM) in women with postmenopausal osteoporosis (PMOP) in Northwest China, and the correlations between GM and bone mineral density (BMD).Methods:From November 2018 to October 2019, postmenopausal women were screened on their initial visits to our hospital, and 24 new osteoporosis (OP) patients, 30 new osteopenia patients and nine negative controls were recruited. Fecal samples were collected for GM DNA extraction, and Illumina platforms were used for high-throughput sequencing of 16S rRNA and metagenome. Species annotation, GM profile and gene functions were viewed and analyzed.Results:GM profiles were significatly different in different groups, and the LDA scores of Peptostreptococcaceae, Romboutsia, unidentified Clostridiales, Megamonas, Erysipelatoclostridium, Klebsiella and Erysipelatoclostridium ramosum were more than 3 in OP group. Metagenomic sequencing analysis indicated that gene numbers were positively correlated with BMD, and metabolism, carbohydrate metabolism, starch and sucrose metabolism and oxidative phosphorylation were negatively correlated with BMD. Receiver operating characteristic curve(ROC) showed that carbohydrate metabolism, starch and sucrose metabolism, amino sugar and nucleotide sugar metabolism, oxidative phosphorylation, respectively, could identify OP with preferable sensitivity and specificity (areas under curve were 0.70, 0.72, 0.73 and 0.75, respectively). Conclusions:High-throughput sequencing had great potential for GM analysis of postmenopausal women with OP, providing evidence of the correlations between GM and BMD.

ABSTRACT

Objective:To study the influence of different feeding patterns on mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in pregnant women with high viral loads who received antiviral medication during pregnancy to the day of delivery.Methods:This prospective cohort study was conducted in Beijing You'an Hospital. From January 1, 2019, to March 31, 2020, and 574 pregnant women with positive hepatitis B surface antigen (HBsAg) and HBV DNA>2×10 5 IU/ml were enrolled. All participants received tenofovir, telbivudine, lamivudine, or propofol tenofovir from 24-28 weeks of gestation and discontinued on the day of delivery, and their neonates were postnatally given routine passive-active immunoprophylaxis. Based on the feeding patterns, the subjects were divided into three groups: breastfeeding ( n=257), bottle-feeding ( n=241) and mixed feeding groups ( n=76). The follow-up data were obtained from liver functions and HBV DNA level of the mothers at 6-8 weeks postpartum and HBV serological markers of infants at 7-12 months. One-way ANOVA, Student-Newman-Keuls, Chi-square test or Fisher exact test, and repeated measures ANOVA were used to analyze the data. Results:The average maternal HBV DNA levels before antiviral treatment did not differ significantly between the three groups [(7.90±0.67), (7.82±0.70), (7.83±0.70) log 10 IU/ml, F=0.912, P>0.05]. HBV DNA level before delivery in the mixed feeding group was slightly lower than that in the breastfeeding and bottle-feeding group [(3.87 ±1.08) vs (4.21±1.17) and (4.30±1.28) log 10 IU/ml, q= 3.052 and 3.831, both P<0.05], while the comparison between the latter two groups showed no significant differences ( P>0.05). After delivery, HBV DNA level in the bottle-feeding group was slightly lower than that in the breastfeeding group [(7.42±0.93) vs (7.69±0.90) log 10 IU/ml, q=4.583, P<0.05]. Among 580 infants (including six pairs of twins), only one bottle-fed infant (0.4%, 1/243) was infected with HBV through MTCT, and none in the breastfeeding or mixed feeding group ( P=0.553). Conclusions:For pregnant women with high viral loads of HBV who have received antiviral medication during pregnancy, although HBV DNA level will rebound after discontinuation upon delivery, breastfeeding is recommended considering it does not increase the risk of MTCT.

ABSTRACT

As non-pharmaceutical interventions, non-invasive electrical neuromodulation techniques are promising in pain management. With many advantages, such as low costs, high usability, and non-invasiveness, they have been exploited to treat multiple types of clinical pain. Proper use of these techniques requires a comprehensive understanding of how they work. In this article, we reviewed recent studies concerning non-invasive electrical peripheral nerve stimulation (transcutaneous electrical nerve stimulation and transcutaneous vagus/vagal nerve stimulation) as well as electrical central nerve stimulation (transcranial direct current stimulation and transcranial alternating current stimulation). Specifically, we discussed their analgesic effects on acute and chronic pain, and the neural mechanisms thereof. We then contrasted the four kinds of nerve stimulation techniques, pointing out limitations of existing studies and proposing directions for future research. With more extensive and in-depth research to overcome these limitations, we shall witness more clinical applications of non-invasive electrical nerve stimulations to alleviate patients' pain and ease the crippling medical and economic burden imposed on patients, their families, and the entire society.

ABSTRACT

Objective To evaluate the implementation and effectiveness of syphilis prevention and control in Hubei Province from 2011 to 2020, to summarize the experience and practice, to analyze the existing problems and causes, and to study and put forward policy and strategy suggestions, so as to provide reference for formulating the national “14th five-year plan” and carrying out the next step of prevention and control work. Methods The National STD Prevention and Control Management Information System, STD Prevention and Control New Media Health Service Platform, National AIDS Comprehensive Prevention Information System, and National Management Information System for the Prevention of AIDS, Syphilis, and Mother-to-Child Transmission of Hepatitis B were used to analyze and evaluate the completion of main prevention and control indicators in Hubei Province. Results Among the 16 evaluation indexes, 10 indexes including the effectiveness of syphilis promotion and training for various groups of people, the proportion of pregnant women undergoing syphilis testing in the monitoring and testing work, and the effectiveness of syphilis prevention and treatment, all met the requirements of the plan. In addition, some of the 5 indexes failed to meet the requirements of the plan. Conclusion Hubei Province has fairly fulfilled the work requirements of the Plan. It is still necessary to strengthen the syphilis prevention and control to ensure the urban pregnant women infected with syphilis and their infants to receive standardized STD diagnosis and treatment services, and the drug users in the drug maintenance treatment clinic to receive free syphilis testing, and to provide referral services for the syphilis antibody positive patients at AIDS voluntary counseling and testing points.

ABSTRACT

Objective To investigate aluminum content in commercially available flour products in Minhang District, Shanghai, and to assess the risk of dietary aluminum exposure among permanent residents in Minhang. Methods From 2018 to 2019, a total of 227 samples including fried flour products, steamed flour products, puffed products and baked flour products, were collected in Minhang District to detect the aluminum content. The food frequency table was used to investigate the consumption of flour foods by permanent residents in Minhang District and to assess population dietary aluminum exposure risk. Results The average content of aluminum in 227 kinds of flour products was 31.66 mg/kg, and the exceeding standard rate was 3.96%. The over-standard foods were all fried flour products, and the over-standard rate reached 10.47%. Moreover, the aluminum over standard rate of flour products produced by itinerant vendors and restaurants was significantly higher than that of flour products produced by supermarkets and manufacturers. The average dietary intake of aluminum in Minhang residents was 0.18 mg/kg per week, accounting for 9.03% of the provisional tolerable weekly intake (PTWI). The aluminum exposure of the population with high consumption of foods was 1.4 mg/kg per week, accounting for 69.90% of the PTWI. Among the four types of flour products, fried flour products had the highest contribution rate to aluminum exposure. The daily consumption of fried flour products in males was significantly higher than that in females (P<0.05), and the 18-34 age group was significantly higher than the 60 years old and above group (P<0.05). Conclusion The risk of the average dietary aluminum exposure of flour foods among Minhang residents is relatively low, but people with high consumption of foods would be confronted with increased health risks. It is necessary to strengthen the supervision on the use of aluminum-containing additives in itinerant vendors and restaurants, and actively advocate reducing the frequency and the consumption of fried flour products, thus reduce the exposure to the high risk of dietary aluminum in fried flour products

ABSTRACT

Objective:To evaluate the effect of tropisetron on pyroptosis in cardiomyocytes subjected to hypoxia-reoxygenation (H/R) and the relationship with α7 nicotinic acetylcholine receptor (α7nAChR).Methods:Routinely cultured H9C2 cardiomyocytes were divided into 4 groups ( n=6 each) using a random number table method: control group (C group), H/R group, tropisetron plus H/R group (Tro+ H/R group), and α7nAchR antagonist MLA plus tropisetron plus H/R group (MLA+ Tro+ H/R group). H/R was produced by 12 h exposure of cells to hypoxia followed by 6 h reoxygenation in the other three groups except group C. Tropisetron at the final concentration of 10 nmol/L was added at 1 h before hypoxia in group Tro+ H/R.In group MLA+ Tro+ H/R, MLA was added at 2 h before hypoxia, and then 1 h later tropisetron at the final concentration of 10 nmol/L was given.At 6 h of reoxygenation, the pyroptosis rate of cardiomyocytes was determined by fluorescence immunostaining of caspase-1-AlexaFluor 488/DAPI, the concentrations of interleukin-1beta (IL-1β) and IL-18 in the supernatant were determined by enzyme-linked immunosorbent assay, the activity of LDH in the supernatant was measured by 2, 4 dinitrophenylhydra-zine colorimetric method, and the expression of α7nAchR, NLRP3 and caspase-1 in cardiomyocytes was detected by Western blot. Results:Compared with group C, the pyroptosis rate, activity of LDH and concentrations of IL-1β and IL-18 in the supernatant were significantly increased, the expression of NLRP3 and caspase-1 was up-regulated, and the expression of α7nAchR was down-regulated in group H/R ( P<0.05). Compared with group H/R, the pyroptosis rate, activity of LDH and concentrations of IL-1β and IL-18 in the supernatant were significantly decreased, the expression of NLRP3 and caspase-1 was down-regulated, and the expression of α7nAchR was up-regulated in group Tro+ H/R ( P<0.05). Compared with group Tro+ H/R, the pyroptosis rate, activity of LDH and concentrations of IL-1β and IL-18 in the supernatant were significantly increased, the expression of NLRP3 and caspase-1 was up-regulated, and the expression of α7nAchR was down-regulated in group MLA+ Tro+ H/R ( P<0.05). Conclusion:α7nAchR is involved in the process of tropisetron inhibiting pyroptosis in cardiomyocytes subjected to H/R.

ABSTRACT

BACKGROUND@#Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive cancers without effective therapy. To explore potential molecular targets in ESCC, we quantified the mutation spectrum and explored the relationship between gene mutation and clinicopathological characteristics and programmed death-ligand 1 (PD-L1) expression.@*METHODS@#Between 2015 and 2019, 29 surgically resected ESCC tissues and adjacent normal tissues from the Fourth Hospital of Hebei Medical University were subjected to targeted next-generation sequencing. The expression levels of PD-L1 were detected by immunohistochemistry. Mutational signatures were extracted from the mutation count matrix by using non-negative matrix factorization. The relationship between detected genomic alterations and clinicopathological characteristics and PD-L1 expression was estimated by Spearman rank correlation analysis.@*RESULTS@#The most frequently mutated gene was TP53 (96.6%, 28/29), followed by NOTCH1 (27.6%, 8/29), EP300 (17.2%, 5/29), and KMT2C (17.2%, 5/29). The most frequently copy number amplified and deleted genes were CCND1/FGF3/FGF4/FGF19 (41.4%, 12/29) and CDKN2A/2B (10.3%, 3/29). By quantifying the contribution of the mutational signatures to the mutation spectrum, we found that the contribution of signature 1, signature 2, signature 10, signature 12, signature 13, and signature 17 was relatively high. Further analysis revealed genetic variants associated with cell cycle, chromatin modification, Notch, and Janus kinase-signal transducer and activator of transcription signaling pathways, which may be key pathways in the development and progression of ESCC. Evaluation of PD-L1 expression in samples showed that 13.8% (4/29) of samples had tumor proportion score ≥1%. 17.2% (5/29) of patients had tumor mutation burden (TMB) above 10 mut/Mb. All samples exhibited microsatellite stability. TMB was significantly associated with lymph node metastasis (r = 0.468, P = 0.010), but not significantly associated with PD-L1 expression (r = 0.246, P = 0.198). There was no significant correlation between PD-L1 expression and detected gene mutations (all P > 0.05).@*CONCLUSION@#Our research initially constructed gene mutation profile related to surgically resected ESCC in high-incidence areas to explore the mechanism underlying ESCC development and potential therapeutic targets.

ABSTRACT

Primary biliary cholangitis (PBC) is a cholestatic liver disease with unclear etiology and pathogenesis. Ursodeoxycholic acid and obeticholic acid are the therapeutic drugs for PBC approved by the US Food and Drug Administration, both of which have the effect of alleviating intrahepatic cholestasis. However, some patients still have poor biochemical response to them, and it is urgent to explore new therapeutic drugs or methods. Fibrates, immunosuppressants, and traditional Chinese medicine have a certain effect in the treatment of patients with PBC, but further studies are needed to analyze their clinical safety and mechanism of action.

OBJECTIVE:To study the heart protective effect of Panax quinquefolium extract of Zebra fish. METHODS :The drug dosage of P. quinquefolium extract and the optimal modeling dose of terfenadine were determined by tolerance test ;24 hours post fertilization (24 hpf),Zebra fish were divided into control group (0.5% dimethyl sulfoxide ),model group (2.5 μg/mL terfenadine),positive control group (2.5 μ g/mL terfenadine + 30 μ g/mL resveratrol) and different mass concentration P. quinquefolium extract groups (2.5 μg/mL terfenadine+5,10,25 μg/mL P. quinquefolium extract,by raw material ). 48 h after incubation,the heart rate and sinus venous-bulbus arteriosus (SV-BA)interval of Zebra fish were used as indexes ,and the heart injury repair rate was calculated to investigate the heart protection of P. quinquefolium extract. Another 24 hpf Zebra fish were divided into blank control group ,model group ,positive control group ,20 batches of P. quinquefolium extract from different producing area groups (5 μg/mL,by raw material ),with same administration route and 48 h of incubation. The heart rate ,SV-BA interval of heart was determined ,heart injury repair rate and heart injury relative repair rate were calculated ;the heart protective effect of P. quinquefolium extract was further validated. RESULTS :Compared with blank control group ,heart rate was decreased significantly(P<0.01),while SV-BA interval was increased significantly in model group (P<0.01). Compared with model group,heart rate of Zebra fish was increased significantly in positive control group and 5,10,25 μg/mL P. quinquefolium extract groups(P<0.01),while SV-BA interval of Zebra fish was shortened significantly in 5,10 μg/mL P. quinquefolium extract groups (P<0.05 or P<0.01);heart injury repair rate of Zebra fish in 5 μg/mL P. quinquefolium extract group reached 73.77%. In validation test ,compared with model group ,heart rate was increased significantly (P<0.01),while SV-BA interval of Zebra fish was decreased significantly in 20 batches of P. quinquefolium extract groups (P<0.01);heart injury repair rate ranged 70.45%-85.78%,and heart injury relative repair rate ranged 75.48%-98.12%. CONCLUSIONS :P. quinquefolium extract has good heart protective effects.

ABSTRACT

Objective:To investigate the efficiency and safety of peritoneal dialysis (PD) in pediatric patients with acute kidney injury (AKI).Method:A retrospective study of children who underwent PD for AKI in the First Affiliated Hospital of Xi’an Jiaotong University from 2003 to 2013 was performed, and the laboratory examinations, the causes, the complication, the prognosis and the risk factors were evaluated.Results:The study included 48 children, with the age of (67.6±51.7) months (ranging from 3 months to 15 years old), including 31 males (64.6%) and 34 co-infections (70.8%). Primary glomerulonephritis (27.1%) was the most common cause of AKI, followed by the hemolytic uremic syndrome (18.7%) and drug induced AKI (18.7%). Peritoneal dialysis was performed manually using percutaneous or adapted catheters. The duration of PD during hospitalization was 11(7,14) days. PD treatment was highly effective in attenuation of toxics retention and correction of electrolyte disturbances (all P<0.05). There were 3 cases of PD-related complications, including 1 case of peritonitis, 1 case of catheter outflow obstruction, 1 case of catheter exit site hematoma, and no child patient died of PD complications. Among the AKI children, 37 cases (77.1%) recovered with the PD treatment and had the catheter successfully removed till discharge, 7 cases (14.6%) needed further peritoneal dialysis and 4 cases (8.3%) died. The serum albumin level was significantly higher in patients who got recovered with PD treatment than other unrecovered cases [(32.6±6.7) g/L vs (23.2±4.3) g/L, t=-3.994, P<0.001]. Conclusions:PD can be safely and efficiently performed for the treatment of pediatric AKI. Low albumin level may be related to poor prognosis of AKI.

ABSTRACT

Objective:To analyze clinical characteristics of cosmetics-related adverse reactions and main allergenic components of cosmetics, to provide guidance for cosmetics-related adverse reaction monitoring, and to provide an objective basis for risk assessment.Methods:A total of 512 patients with suspected cosmetic adverse reactions were collected from the outpatient clinic of Chongqing Traditional Chinese Medicine Hospital from March 2018 to October 2019, including 14 males and 498 females. A uniform cosmetic adverse reaction report card was filled in, and medical history of patients and related information about the used cosmetics were recorded; 103 patients (3 males and 100 females) were subjected to patch test with their own cosmetics or cosmetic ingredients, and 48- and 72-hour patch test results were combined for comprehensive determination and analysis.Results:Among the 512 cases of suspected cosmetic adverse reactions, contact dermatitis (495 cases, 96.7%) was the most common manifestation. Cosmetic adverse reactions mainly manifested as erythema (501 cases, 97.9%), papules (313, 61.1%), edema (249, 48.6%), and scaling (166, 32.4%) ; main symptoms included itching (480, 93.8%), burning sensation (359, 70.1%), and tense sensation (297, 58.0%). Patch test with cosmetic ingredients showed positive reactions in 71 of 103 cases, and thimerosal was the allergen mostly liable to cause adverse reactions (31 cases, 30.1%), followed by sodium dodecyl sulfate (29 cases, 28.2%), Peru balsam (17 cases, 16.5%), bronopol (12 cases, 11.7%) and triethanoamine (10 cases, 9.7%). The cosmetic allergens were divided into 14 categories, and the top 4 categories with high positive patch test rates were emulsifiers (54 cases, 45.8%), preservatives (47 cases, 39.8%), fragrances (17 cases, 14.4%) and surfactants (10 cases, 8.5%). Positive patch test reactions were observed in 2 males and 69 females, and there was no significant difference in the positive rate between males and females (2/3 vs. 69/100, χ2 = 0.01, P > 0.05) ; there was also no significant difference in the positive rate among the groups aged 18 - 29 years (34%), 30 - 49 years (34%) and 50 - 70 years (32.4%; χ2 = 0.693, P > 0.05) . Conclusions:Contact dermatitis is the most common adverse reaction to cosmetics. Among the diverse allergenic components of cosmetics, thimerosal is the allergen that is mostly liable to cause adverse reactions, followed by sodium dodecyl sulfate, Peru balsam, bronopol and triethanoamine.

ABSTRACT

Objective:To screen and evaluate sunscreen cosmetics for sensitive facial skin.Methods:From June to August in 2019, 40 subjects with positive lactic acid sting test were recruited from the staff of Chongqing Traditional Chinese Medicine Hospital, and subjected to human skin closed patch testing with 4 kinds of sunscreen cosmetics for sensitive skin (marked as products Ⅰ, Ⅱ, Ⅲ, Ⅳ respectively) separately. Then, the 40 subjects were equally divided into 2 groups to apply 2 sunscreen products with relatively higher safety (according to the above closed patch testing results) on the face respectively. Erythema, edema and desquamation were evaluated at baseline, 2 and 4 weeks after application of the 2 products, and non-invasive measurement methods were used to detect transepidermal water loss (TEWL) , stratum corneum hydration, skin melanin content and skin sebum content. In additon, the 2 products were applied on the back of the subjects separately, and an ultraviolet solar simulator was used to determine the sun protection factor (SPF, n = 12) and protection factor of UVA (PFA, n = 11) . Measurement data were compared using paired t test and one-way analysis of variance, and nonparametric data were compared using Wilcoxon signed rank test. Results:Patch testing showed that only 1 subject developed a grade 1 reaction to the sunscreen product Ⅲ, no subjects showed positive reactions to the product Ⅳ, and the safety of products Ⅲ and Ⅳ was higher than that of the other 2 products. Subjective safety evaluation revealed that the degree of erythema after 4-week application of products Ⅲ and Ⅳ was significantly lower than that before application (Wilcoxon signed rank test, Z = 4.73, 4.82 respectively, both P < 0.05) . Objective efficacy evaluation revealed that the TEWL, stratum corneum hydration and skin melanin content significantly differed among different time points (baseline, after 2- and 4-week application of products Ⅲ and Ⅳ, all P < 0.05); after 4-week application of products Ⅲ and Ⅳ, the TEWL (30.05 ± 1.47, 30.37 ± 1.28 respectively) and skin melanin content (112.58 ± 7.34, 103.47 ± 5.48 respectively) were significantly lower than those before application (all P < 0.05) , and the stratum corneum hydration (62.35 ± 2.67, 63.72 ± 2.54 respectively) was significantly higher than that before application (both P < 0.05) . At week 4, the skin melanin content was significantly lower in the product Ⅳ group (103.47 ± 5.48) than in the product Ⅲ group (112.58 ± 7.34, t = 8.45, P < 0.05) . The SPF and PFA values of the product Ⅳ (51.8 ± 2.9, 10.1 ± 1.2 respectively) were both significantly higher than those of the product Ⅲ (31.5 ± 2.6, 7.4 ± 0.7, t = 15.34, 24.66, respectively, both P < 0.05) . Conclusion:Comprehensive application of closed patch testing, long-term application test and sun protection index determination can be used to screen and evaluate the safety and efficacy of sunscreen cosmetics for sensitive facial skin.

ABSTRACT

Liver fibrosis is commonly seen in various chronic liver diseases. In history, traditional Chinese medicine (TCM) clinical practice based on syndrome differentiation and treatment formed unique experience in the diagnosis and treatment of liver fibrosis; in recent years, studies based on experimental exploration and evidence-based medicine have formed effective Chinese patent drugs and experienced prescriptions for the treatment of liver fibrosis, as well as integrated traditional Chinese and Western medicine regimens. With the improvement in the quality of TCM drugs and the development of related clinical studies, new TCM drugs with stable quality and marked clinical effect will be launched for the treatment of liver fibrosis, so as to meet the clinical needs of patients with chronic liver diseases and promote the modern and international development of TCM.

ABSTRACT

BACKGROUND@#The development of auditory and speech perception ability of children with hearing loss is affected by many factors after they undergo cochlear implantation (CI). Age at CI (CI age) appears to play an important role among these factors. This study aimed to evaluate the development of auditory and speech perception ability and explore the impact of CI age on children with pre-lingual deafness present before 3 years of age.@*METHODS@#Two hundred and seventy-eight children with pre-lingual deafness (176 boys and 102 girls) were included in this study, and the CI age ranged from 6 to 36 months (mean age, 19 months). Categorical auditory performance (CAP) was assessed to evaluate auditory ability, and the speech intelligibility rating was used to evaluate speech intelligibility.

ABSTRACT

Background@#The development of auditory and speech perception ability of children with hearing loss is affected by many factors after they undergo cochlear implantation (CI). Age at CI (CI age) appears to play an important role among these factors. This study aimed to evaluate the development of auditory and speech perception ability and explore the impact of CI age on children with prelingual deafness present before 3 years of age.@*Methods@#Two hundred and seventy-eight children with pre-lingual deafness (176 boys and 102 girls) were included in this study, and the CI age ranged from 6 to 36 months (mean age, 19 months). Categorical auditory performance (CAP) was assessed to evaluate auditory ability, and the speech intelligibility rating was used to evaluate speech intelligibility. The evaluations were performed before CI and 1, 3, 6, 12, 18, 24, 36, 48, and 60 months after CI.@*Results@#The auditory ability of the pre-lingually hearing-impaired children showed the fastest development within 6 months after CI (k = 0.524, t = 30.992, P < 0.05); then, the progress started to decelerate (k = 0.14, t = 3.704, P < 0.05) and entered a plateau at the 24th month (k = 0.03, t = 1.908, P < 0.05). Speech intelligibility showed the fastest improvement between the 12th and 24th months after CI (k = 0.138, t = 5.365, P < 0.05); then, the progress started to decelerate (k = 0.026, t = 1.465, P < 0.05) and entered a plateau at the 48th month (k = 0.012, t = 1.542, P < 0.05). The CI age had no statistical significant effect on the auditory and speech abilities starting at 2 years after CI (P < 0.05). The optimal cutoff age for CI was 15 months.@*Conclusions@#Within 5 years after CI, the auditory and speech ability of young hearing-impaired children continuously improved, although speech development lagged behind that of hearing. An earlier CI age is recommended; the optimal cutoff age for CI is at 15 months.

ABSTRACT

Objective To evaluate the role of cyclic adenosine monophosphate-protein kinase A-cAMP response element-binding protein (cAMP-PKA-CREB) signaling pathway in hypoxic preconditioninginduced reduction of propofol-induced central neurotoxicity in the developing rats.Methods A total of 70 SPF male Sprague-Dawley rats,aged 7 days,weighing 10-15 g,were divided into 7 groups (n=10 each) using a random number table method:normal saline group (N group),propofol group (P group),hypoxic preconditioning plus propofol group (HP group),hypoxic preconditioning plus propofol plus PKA inhibitor H89 group (HPH group),propofol plus PKA agonist SP-CAMP group (PS group),normal saline injected via the lateral cerebral ventricle group (NI group),and 5% dimethyl sulfoxide (DMSO) injected via the lateral cerebral ventricle group (DI group).In P group,propofol 50 mg/kg was intraperitoneally injected,and an increment of propofol 50 mg/kg was given after recovery of righting reflex.The equal volume of normal saline was given instead in N group.In HP group,hypoxic preconditioning (rats were subjected to 5 cycles of 10-min hypoxia of 8% O2 and 1O-min normoxia of 21% O2) was performed,and propofol was intraperitoneally injected at 2 h after the end of hypoxic preconditioning and the method was similar to those previously described in P group.In HPH group,H89 5 μmol/5 μl was injected via the lateral cerebral ventricle,and 30 min later the other treatment was similar to those previously described in HP group.In PS group,SP-CAMP 20 nmol/5 μl was injected via the lateral cerebral ventricle,and 30 min later propofol was injected using the method previously described in P group.In NI and DI groups,5 μl normal saline and 5% DMSO were injected via the lateral cerebral ventricle,respectively.Rats were immediately sacrificed after the righting reflex was recovered,brains were removed and hippocampi were isolated and cut into sections which were stained with haematoxylin and eosin for determination of PKAc and p-CREB positive cells (by i mmuno-histochemistry) and expression of cleaved caspase-3,Bcl-2,Bax,PKAc and posphorylated (p-CREB) protein (by Western blot).Results Compared with N group,the expression of cleaved caspase-3 and Bax was significantly up-regulated,the expression of Bcl-2,PKAc and p-CREB was downregulated,and the percentage of PKAc and p-CREB positive cells was decreased (P<0.05),hippocampal cells had irregular arrangement,and cells was atrophied in P group.Compared with P group,the expression of cleaved caspase-3 was significantly down-regulated,the expression of Bcl-2,PKAc and p-CREB was up-regulated,and the percentage of PKAc and p-CREB positive cells was increased in HP and PS groups,and the expression of Bax was down-regulated (P<0.05),the hippocampal cells were arranged neatly,the cytoplasm was abundant,and the nuclei were visible in HP group.Compared with HP group,the expression of cleaved caspase-3 was significantly up-regulated,the expression of Bcl-2,PKAc and p-CREB protein was down-regulated and the percentage of PKAc and p-CREB positive cells was decreased (P<0.05),the cells had irregular arrangement and shrinked,and nuclear condensation was found in cells in HPH group.Conclusion The mechanism by which hypoxic preconditioning reduces propofol-induced central neurotoxicity may be related to activating cAMP-PKA-CREB signaling pathway in the developing rats.
