This paper summarized the clinical experience of using the method of “returning fire to its origin” for treatment of paroxysmal sympathetic hyperactivity （PSH）. According to the causes and clinical characteristics of PSH， the author believes that the deficiency of kidney qi， and the loss of yin and yang are the basis of the pathogenesis of PSH. Fright causes qi to be chaotic as the triggering mechanism of PSH. The key mechanism of PSH is that the deficiency yang with upper manifestation， and the fire does not return to its origin. The treatment should be nourishing yin and astringing yang， by taking modified Yinhuo Decoction （引火汤） internally， and receiving warm moxibustion as the first choice externally with selected acupoints Guanyuan （CV 4）， Mingmen （GV 4）， and bilateral Yongquan （KI 1）； For prevention， attention should be paid to take care of stomach qi， support healthy qi， and cultivate original qi.

Objective:To analyze the seroepidemiological characteristics of hepatitis B virus (HBV) infection among adolescents aged 0-14 years in Henan Province and to evaluate the effectiveness of the childhood hepatitis B vaccine (HepB) immunization program.Methods:From September 2021 to March 2022, a total of 4 883 adolescents aged 0-14 years were selected from 25 villages or communities of 18 provincial-level cities in Henan Province by using the multi-stage random cluster sampling method. Demographic data were collected through questionnaires. The 3 ml of blood samples were collected from individuals aged 0-4 years and 5 ml of blood samples were collected from individuals aged 5-14 years to test HBsAg, HBcAb and HBsAb. Data on vaccination were collected through Henan Provincial Immunization Information System and hepatitis B cases in Henan Province were collected through China Infectious Disease Reporting System. The effectiveness of the childhood HepB immunization program was analyzed.Results:The average age of 4 883 subjects was (7.32±2.81) years old. The positive rates of HBsAg and HBcAb were 0.1% (7/4 883) and 1.0% (50/4 883), and the population standardized rates were 0.3% and 1.7%. In 2002, the positive rate of HBsAg among adolescents aged 0-14 years in Henan Province was 3.39%. Compared with that in 2002, the number of chronic HBV infections among adolescents in Henan Province in 2022 decreased by about 0.7 million. In 2002, the vaccination rate of newborns who completed all three doses of vaccine was 6.26%. In 2003, the vaccination rate of the hepatitis B vaccine rose rapidly, reaching 90% in 2013 for the first time. After 2014, the vaccination rate in Henan Province continued to remain above 95%. The proportion of cases among children aged 1-4 years in clinical reports decreased from 0.43% (1 108/256 566) in 2006 to 0.01% (78/80 655) in 2021. The proportion of cases among adolescents aged 5-19 years decreased from 18.21% (46 710/256 566) in 2006 to 1.1% (827/80 655) in 2021.Conclusions:From 2002 to 2022, the positive rate of HBsAg among adolescents aged 0-14 years has decreased significantly in Henan Province.

Objective:To retrospectively compare the clinical efficacy of two PDE3 inhibitors, oplinone and Milrinone, in order to evaluate which drug has better effects on the improvement of cardiac function, protection of renal function and adverse effects of arrhythmia.Methods:A total of 41 neonates with congenital heart disease after biventricular treatment under cardiopulmonary bypass in the Department of Cardiothoracic Surgery at Soochow University Children's Hospital during 2018-2022 were collected. The experimental group was divided into two groups: Oprilinone(25 cases) and Milinone(16 cases). A retrospective study was conducted on the incidence of renal function, cardiac function improvement and arrhythmia in the children.Results:On the first day after operation, EF in both groups decreased significantly compared with that before operation( P<0.01); On day 4 after surgery, EF in the oprilinone group was significantly higher than that on day 1 after surgery( P<0.01), Milrinone group was slightly higher than that on day 1 after surgery( P<0.05), and EF in oprilinone group was significantly higher than that in Milinone group during the same period( P<0.01); EF in Milinone group continued to increase on day 7 compared with day 4( P<0.01), but there was no significant difference between the two groups. Long-term follow-up showed that there was no significant difference in EF value in the oprilinone intervention group on day 7 after surgery( P<0.05), and the long-term EF in Milinone group was higher than that at 7 days after surgery( P<0.05). The creatinine level in the oprinone intervention group continued to decrease on the 4th and 7th day after surgery( P<0.01; P<0.05); The creatinine level of Milinone group on day 4 after surgery was significantly lower than that on day 1 after surgery( P<0.01), the decrease was not significant on the 7th day after surgery compared with the 4th day after surgery; The creatinine level in the oprilinone group was lower than that in the Milrinone group on day 7 after surgery( P<0.05). The rate of arrhythmia in children was slightly decreased in the intervention group of olplinone. There was no change in the Milinone group. Conclusion:Oplinone improved cardiac function better than Milrinone, and the recovery time to normal cardiac function was shorter. In terms of renal function protection, oplinone was stronger than Milrinone, and the protective effect of oplinone on kidney lasted longer. No significant abnormalities were found with respect to adverse reactions, such as the incidence of arrhythmia.

Objective:To study the changes of stenotic segment trachea diameter, trachea length and carina angle before and after slide tracheoplasty.Methods:From January 2010 to January 2018, 77 children with congenital tracheal stenosis(female=36) with complete clinical data accepted slide tracheoplasty in Shanghai Children's Medical Center were selected as the observation group. The diameter of stenosis segment, the length of stenosis segment, the full length of trachea and carina angle were measured by CT image, and the ratio of stenosis segment length to full trachea length was calculated. A group of children with normal trachea morphology and the same sample number, and they had no significant difference in age, height and weight were selected as the control group.Results:The median operative age of 77 children in the observation group was 1.3(1.1, 1.9)years old, the height was 76.0(72.0, 83.0)cm, and the weight was 9.0(7.9, 10.8)kg. The age, height and weight of 77 children in the control group were 1.5(1.0, 2.0) years old and 78.0(71.0, 85.0) cm, 9.2(7.9, 11.0) kg respectively. After slide tracheoplasty, the diameter of trachea in the stenotic segment of children increased from 2.7 mm to 4.4 mm, which was increased by 63.0%( P<0.001), but still smaller than that of children in the control group(6.1 mm). The average length of trachea was shortened by 0.7 cm( P<0.001), and there was no significant difference between the total length of trachea(5.4 cm) and the total length of trachea(5.5 cm). The postoperative carina angle decreased by 27.9°( P<0.001), there was no significant difference in postoperative carina angle between the observation group(93.0°) and the control group(90.7°). Conclusion:The diameter of reconstructed trachea in children with CTS is significantly increased, the length and carina angle of trachea become smaller after slide tracheoplasty. The morphology of trachea is more similar to children in the control group.

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease with unknown etiology, and patients with poor response to ursodeoxycholic acid and obeticholic acid may eventually progress to liver cirrhosis and even liver failure. Liver transplantation is the only effective treatment method for PBC at present. This article elaborates on liver transplantation, survival time after liver transplantation, complications, recurrence of PBC after liver transplantation, and prospects and challenges of liver transplantation in patients with PBC, so as to provide a reference for clinical outcome and treatment after liver transplantation for PBC.

Objective: To describe online learning and eye strain situation of college students during the COVID-19 outbreak, to provide a scientific basis for guiding students eye health. Methods: A self-filled electronic questionnaire survey through questionnaire star was administered to college students across China. Information about online learning and eye strain of 1 046 college students during the epidemic was collected in Hefei, Anhui Province from March 16 to 20, 2020. The univariate and multivariate Logistic regression analysis were performed to analyze the association between online learning and eye strain of college students. Results: The rate of eye strain during online learning was 72.1%, totally of 68.4% in 421 male students and 74.6% in 625 female students. Boys with online learning time <6 h/d, slow internet access，difficulty in understanding online class reported higher rate of eye strain than girls( χ 2=17.36,8.72,7.02, P ＜0.05). Freshmen reported the highest rate of slow internet access occasionally and active online class( χ 2=15.26,16.11, P ＜0.05), junior students reported highest rate of online learning time <6 h/d, and easy understandable online class( χ 2=15.33,32.59, P ＜0.05), medical college students reported higher rate of slow internet access, inactive online class than non-medical college students( χ 2=11.79,11.03, P ＜0.05). Multivariate Logistic regression analysis showed that odds ratio( OR ) of eye strain in females was 1.40 (1.06-1.87), compared with males; the OR of eye strain were 1.43 (1.01-2.03) and 1.54 (1.10-2.15) in the groups with online learning time 6-<8 h/d and ≥8 h/d, respectively, compared with the group with online learning time <6 h/d, the OR of eye strain in the groups with slow internet access was 2.28 (1.25-4.14), compared with students without slow internet access, the OR of eye strain in the capable to understand and difficult to understand group were 2.54 (1.73-3.74) and 5.40 (2.70-10.80) respectively, compared with the easy to understand group. Conclusion Female students, online learing time ≥ 8 h/d, slow internet access, difficult to understand class content were positively related with college students eye strain. Attention should be paid to the eye health of college students to reduce the adverse effects of online learning on vision.during the COVID-19 epidemic.

Objective To analyze the genetic characteristics of mumps virus ( MuV) isolated from an outbreak in Henan province in 2016 and to provide reference data for the control of mumps in Henan prov-ince. Methods Swab specimens were collected from a mumps outbreak in Henan province in 2016. One virus strain was selected for whole genome sequencing after virus isolation and genotyping. MEGA7. 0 soft-ware was used to construct phylogenetic tree, to calculate P-distance and to analyze the characteristics of genes encoding small hydrophobic protein ( SH ) , fusion protein ( F ) and hemagglutinin neuraminidase ( HN) . Results Five swab specimens were collected in the outbreak and five MuV strains were successfully obtained. Phylogenetic analysis showed that all of them belonged to genotype F with a P-distance of 0. 047 (0. 046-0. 049 ) with the reference strain. The P-distance among the five MuV strains was 0. 001 ( 0-0. 003). Results of the whole genome sequencing of one MuV strain showed that the P-distance with the ref-erence virus was 0. 053 (0. 018-0. 072) and the smallest P-distance with genotype F was 0. 018. Compared with the vaccine strain (HQ416907. 1), the amino acid at 28-30 site of SH protein was IML. The 91, 195 and 383 amino acid sites in F protein were related to the pathogenicity of MuV, but no mutations were found in these sites. Some mutations were found in HN protein, such as P354Q, E356D and K464N, which were associated with the immunological characteristics of MuV. Conclusions MuV strains isolated from the out-break in Henan province in 2016 belonged to genotype F. The genetic characteristics of these MuV strains were similar to those prevalent in other provinces of China.

Objective: Analyze the genetic characteristic of Hemagglutinin(H) gene of measles viruses isolated in Henan Province in 2017. Methods: Swab samples collected from 7 lab confirmed measles cases, and we got the measles virus by Vero/Slam inoculation. Fragment of H genes were amplified by reverse transcription polymerase chain reaction(RT-PCR), then the PCR products were sequenced and analyzed. Results: The age of the 7 measles confirmed cases were between 1 and 50 years old, and all of them were males. All the 7 measles viruses were identified as H1a genotype, and the average distance of the nucleotides and the amino acids was 0.005, respectively. Compared with the Shanghai-191/China-vaccine, there were some changes in isolated virus, such as 240^th, 397^th and 381^st sites in the amino acid sequence. Conclusion The measles genotype which isolated in Henan Province in 2017 was H1a. There were some difference from Shanghai-191/China-vaccine in the nucleotides sequence of H gene, which suggested that it′s necessary to strengthen the monitor the variation of measles virus.
