Objective To investigate the characteristic changes of the auditory brainstem response (ABR) of normal hearing newborn and infants .Methods One hundred and forty -five cases (290 ears) normal hearing new-born and infants were enrolled for ABR test .Before that they passed the distortion product otoacoustic emissions and acoustic immitance test previously .According to age ,13 (26 ears) of 145 were included in the 1~7 days age group ,17 (34 ears) was in the 30~59 days age group ,20 (40 ears) in the 2~4 months age group ,19 (38 ears) in the 5~7 months age group ,17 (34 ears) in the 8~10 months age group ,18 (36 ears) in the 11~13 months age group ,12 (24 ears) in the 14~16 months age group ,13 (26 ears) in the 17~19 months age group ,16 (32 ears) in the more than 20~24 months age group .The control group was 20 (40 ears) normal hearing young persons (18~25 years old) .The variation of the peak latency and interpeak latency of waves were observed ,and compared with the normal young people .Results In 70 dB nHL click sound stimulus ,the peak latency and interpeak latency ofⅠ ,Ⅲ ,Ⅴ waves of normal hearing neonates and infants progressively shortened as they grew older .As they ap-proach 18 months or more old age ,their peak latency and interpeak latency of Ⅰ ,Ⅲ ,Ⅴ waves may be same as nor-mal young people .Conclusion With the growth of the age ,the peak latency and interpeak latency of Ⅰ ,Ⅲ ,Ⅴwaves of normal hearing newborn and infants gradually shortened .The reason may be related to the maturity of the auditory system .

Objective: To explore the differences in mental health between freshmen with and without disabilities. Methods: A comparative analysis of 6 114 freshmen with and without disabilities from an undergraduate college in Nanjing from 2018 to 2020 was measured by the SCL-90 Mental Health Symptom Self Rating Scale. Results: The positive detection rate of SCL-90 was 23.29%, and the positive rate of disabled students was significantly higher than healthy students( χ 2= 28.35 , P <0.01); Disabled freshmen were significantly higher than healthy freshmen in the levels of all factors( P <0.05); A longitudinal comparison of the positive detection rate of SCL-90 between the two groups of freshmen in three years, there was no statistical difference between the disabled freshmen( χ 2=5.82, P =0.06), there was a statistical difference in healthy freshmen( χ 2=29.43, P <0.01); After interview with positive factor students, the composition ratio of freshmen with disabled of A and B was higher than that of healthy freshmen( χ 2= 7.09 , P <0.05). Conclusion Mental health level of freshmen with disabled is lower than that of healthy freshmen. Mental health among freshmen without disabilities is worsening. The mental health of disabled freshmen is relatively stable, however, the proportion of students with psychological problems is relatively high, which requires attention.

Objective To survey on the intention of seeking pediatric service in primary care institutions among parents in Shanghai rural area .Methods A survey on the intention of pediatric care-seeking was conducted during June to December in 2016 using simple random sampling method in Fengxian District of Shanghai.Subjects were choosen from the parents visiting pediatric department in Xidu Community Health Center ( CHC) (289 ), parents having kids in the local kindergarten ( 121), and medical staff working in this district with children under age 14 (205).Results Total 615 individuals were surveyed and 572 responded with a response rate of 93.0%.The age of participants was (32.1 ±6.4) years, and they were 191 males and 381 females.Among all responders, 88.4%(505/571) wanted to have pediatric service in CHC, 9.5%(54/571) did not care and 2.1%(12/571) did not want.If the CHC had service provided by pediatric specialists , 81.5%( 466/572) intended to seek pediatric care in CHC , 10.8%(62/572) did not care and 7.7%(44/572) did not want.If the general practitioner provided pediatric service, the rates were 51.9%(297/572), 12.1%(69/572) and 36.0%(206/572), respectively.In comparison, the intention to seek care provided by pediatric specialists was stronger (Z ＝-12.553, P ＜0.001). Parents who were not medical professionals preferred to set pediatric clinic in CHC ( OR ＝6.849, P ＝0.026); parents who were not Shanghai residents preferred to see pediatric specialists (OR＝2.732, P＝0.033).Parents who were older than 30 years (OR＝1.770, P＝0.013), who were medical professionals (OR＝2.093, P＝0.003) or having children aged 0-3 years (OR＝2.154, P＝0.001) preferred to visit general practice clinics .Only 11.7%(66/562) would choose CHC when their children were ill . Parents who were older than 30 years (OR＝2.083, P＝0.038) or whose family income was less than 8 000 yuan/m (OR＝1.967, P＝0.030) preferred to choose CHC.The reason for choosing CHC was close to home for 93.8%(61/65) and good treatment effect for only 18.5%(12/65).The expectations of pediatrics in CHC included more comprehensive medical equipment (82.2%, 466/567), higher service level (77.8%,441/567), more complete medicine stock (74.8%, 424/567)and regular expert outpatient service (70.0%, 397/567).Conclusion Parents have strong demands of providing pediatric care in CHC, but the pediatric skills of general practitioners are not trusted .The CHC should upgrade related facilities and medicine stock for further improving the quality of pediatric service .

Conclusions The systematic intervention can effectively improve alarm setting correctly and nurse’ s capability of early-warning, and ensure quality of critical patients’ care.

Objective To compare the toxicity between different dose fractionation regimens in postoperative radiotherapy for prostate cancer. Methods Patients with prostate cancer who received postoperative radiotherapy with moderate hypo-fractionation ( 62. 75 Gy in 25 fractions, 2. 51 Gy per fraction) or conventional fractionation (72 Gy in 36 fractions, 2 Gy per fractions) in our hospital from 2011 to 2017 were enrolled as subjects.All patients received intensity-modulated radiotherapy and daily cone-beam computed tomography image-guided radiotherapy. According to the propensity score matching ( PSM ) method, 35 patients treated with moderately hypo-fractionated radiotherapy were matched to 35 patients treated with conventionally fractionated radiotherapy based on age, irradiated volume, hormonal therapy, interval between surgery and radiotherapy, and comorbidities ( diabetes and hypertension). Toxicity was evaluated according to Radiation Therapy Oncology Group criteria. Comparison was made by the Fisher's exact probability test. Results One hundred and thirteen patients, consisting of forty-one in moderate hypo-fractionation group and seventy-two in conventional fractionation group, were enrolled as subjects. The median follow-up time in the two groups was 5. 6 and 45. 0 months, respectively. There were no significant differences in incidence rates of grade 2 acute gastrointestinal (GI) or genitourinary (GU) toxicity between the two groups ( 7% vs. 7%, P＝ 1. 000; 15% vs. 17%, P＝ 0. 847). After PSM, there were still no significant differences in incidence rates of grade 2 acute GI or GU toxicity between the two groups (9% vs. 11%, P＝0. 814; 14% vs. 11%, P＝ 0. 670). None of patients reported ≥grade 3 GI or GU toxicity. Conclusions Preliminary results show that moderate hypo-fractionation, compared with conventional fractionation, does not increase the risk of acute GI or GU toxicity in patients undergoing postoperative radiotherapy for prostate cancer.

Precise biomarker development is a key step in disease management. However, most of the published biomarkers were derived from a relatively small number of samples with supervised approaches. Recent advances in unsupervised machine learning promise to leverage very large data-sets for making better predictions of disease biomarkers. Denoising autoencoder (DA) is one of the unsupervised deep learning algorithms, which is a stochastic version of autoencoder techniques. The principle of DA is to force the hidden layer of autoencoder to capture more robust features by reconstructing a clean input from a corrupted one. Here, a DA model was applied to analyze inte-grated transcriptomic data from 13 published lung cancer studies, which consisted of 1916 human lung tissue samples. Using DA, we discovered a molecular signature composed of multiple genes for lung adenocarcinoma (ADC). In independent validation cohorts, the proposed molecular signature is proved to be an effective classifier for lung cancer histological subtypes. Also, this signature suc-cessfully predicts clinical outcome in lung ADC, which is independent of traditional prognostic fac-tors. More importantly, this signature exhibits a superior prognostic power compared with the other published prognostic genes. Our study suggests that unsupervised learning is helpful for bio-marker development in the era of precision medicine.

Objective To identify factors associated with gastrointestinal heat retention in preschool children,and to provide a foundational understanding for future clinical investigations. Methods A case-control study was performed,which involved children from kindergartens in the Longgang District of Shenzhen City,Guangdong Province,from May to July 2021. Using the Children's Gastrointestinal Heat Retention Diagnostic Self-assessment Scale,subjects were allocated into a case group (children diagnosed with gastrointestinal heat retention) and a control group (children without this condition). An online survey was used to collect data on dietary behaviors,caregivers' feeding behaviors,early antibiotic use,daily routines,and birth conditions. SPSS 27.0 software was used to facilitate precise sociodemographic matching and paired logistic regression analysis to explore the association between gastrointestinal heat retention and the above factors. Results From the analysis of 51,252 matched cases,the study found that several factors contributed to an increased risk of gastrointestinal heat retention. These factors included reduced food intake compared to peers,reports of picky eating by caregivers,distractions during meals,pronounced dietary preferences,disinterest in food,meal durations ≥ 25 min,reluctance to sample new foods,consistent refusal of specific food types for over one month,irregular meal locations,coercive feeding practices,use of micronutrient supplements,allowing children too much freedom in food choice,persuading children to eat,infrequent encouragement to experiment with new foods,early antibiotic introduction,inadequate sleep,and premature birth (P<0.05). In contrast,exclusive breastfeeding in the first six months,engagement in moderate to massive physical activity,and regular napping patterns were associated with a reduced risk of gastrointestinal heat retention (P<0.05). Conclusion The suboptimal dietary habits,improper feeding practices,insufficient physical activity,inadequate sleep,and premature antibiotic exposure may be significant risk factors for gastrointestinal heat retention. Future research dedicated to unraveling the cause of gastrointestinal heat retention should prioritize these elements.
