Objective:
To investigate the current status of syphilis treatment and its influencing factors among pregnant and lying-in women in Zhejiang Province, so as to promote the standardized treatment for pregnant and lying-in women with syphilis.
Methods :
The sociodemographic characteristics ( age, educational level, ethnicity, marital status, occupation ), fertility ( gravidity, parity, number of children, and adverse pregnancy history ), gestational week at the first antenatal care visit and syphilis treatment ( treatment or not, standardized treatment or not, and antibody titer ) were collected from the pregnant and lying-in women with syphilis infections delivered in Zhejiang Province in 2018, based on the Zhejiang Provincial Information Management System for Prevention of Mother-to-Child Transmission of AIDS, Syphilis and Hepatitis B. Factors affecting the treatment of syphilis infections were identified using a structural-equation model.
Results:
A total of 2 061 pregnant and lying-in women with syphilis infections were included, with a median age of 29 years and a mean gestational week at the first antenatal care visit of ( 14.33±11.85 ) weeks, and there were 844 women ( 40.95% ) diagnosed in early pregnancy ( <13 weeks of gestational age ). There were 1 978 cases ( 95.97% ) receiving syphilis treatment, and 1 616 cases ( 78.41% ) received standardized treatment. The structural-equation modeling analysis showed that the gestational age at the first antenatal care visit and fertility had direct impacts on the treatment of syphilis infections among pregnant and lying-in women, with standardized path coefficients of -0.187 and -0.157 (both P<0.05 ), respectively, and the sociodemographic characteristics affected the treatment of syphilis through the mediating role of fertility, with a standardized path coefficient of 0.070 ( P<0.05 ).
Conclusions
The proportion of syphilis treatment is more than 95% among pregnant and lying-in women in Zhejiang Province, which achieves the required process criteria for validation of elimination of mother-to-child transmission of HIV and syphilis. Gestational week at the first antenatal care visit, fertility status, and sociodemographic characteristics are factors affecting the treatment syphilis infections during pregnancy.

AIM: To observe the effects of carvedilol on murine viral myocarditis model. METHODS: A total of 188 inbred male BALB/c mice of 4-6 weeks were divided into 4 groups: myocarditis group (group C, n=60), metoprolol treatment group (group M, n=60), carvedilol treatment group (group K, n=60), control group (group B, n=8). Myocardial histopathololgic changes were observed. The concentrations of cardiac troponin I (cTn-I) were detected by chemiluminescence immunoassay (CLIA). Western blotting was performed to analyze the contents of phosphorylated p38MAPK in myocardium. RESULTS: Metropolol and carvedilol lightened myocardial histopathololgic changes at acute stage, decreased cTn-I concentrations and myocardial phosphorylated p38MAPK value compared with myocarditis group. Treatment with carvedilol was more effective than treated with metropolol on those indexes. CONCLUSION: Carvedilol protects against viral myocarditis by inhibition of p38MAPK signal transduction pathway through blockade of β_1 and β_2 adrenergic receptors.

Objective:
To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL.
Methods:
Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL.
Results:
A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β'= -0.179 ), diopter ( β'= 0.208 ), eyesight with glasses ( β'= -0.229 ) and anxiety ( β'= 0.439 ) were influencing factors for VRQL.
Conclusion
The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

Objective To study the expressions of programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) in liver injury of acute liver failure (ALF) in rats and the role of PD-1/ PD-L1 in liver inflammatory injury. Methods SD rats were divided into two groups: 6 in normal group and 30 in ALF model group. The ALF models in rats were induced by D-galactosamine (D-Gal). The sera and hepatic tissue samples were collected at 12, 24, 48, 72 and 120 hours after D-Gal injection. Expressions of PD-1 mRNA and PD-L1 mRNA in hepatic tissue samples were detected by reverse transcription-polymerase chain reaction (RT-PCR). Comparison of measurement data between groups was done by t test. Correlation test was performed using Pearson linear correlation analysis. Results The levels of alanine animotransferase (ALT) and aspartate animotransferase (AST) at 12 h of D-Gal injection were (217. 3±33. 7) U/L and (397. 2± 101.3) U/L, respectively,which were both significantly higher than those in normal group [(30. 5 ±3. 1) U/L and (78. 6±4.2) U/L, respectively; t=-8. 921 and -6. 121, respectively; both P<0.01] and peaked at 48 h.The expression of PD-1 mRNA in model group at 12 h (0. 385±0. 074) was significantly higher than that in normal group (0. 097±0.009) (t= -7. 725, P<0.01) , and peaked at 48 h (0. 927±0. 132),then decreased obviously at 72 h. The expression of PD-L1 mRNA in the liver tissue of normal rats was very little, while that in model group was increased gradually over time, then peaked at 48 h (0. 593±0. 105; t =- 10. 076, P<0. 01). The expressions of PD-1 and PD-L1 were positively correlated with ALT level (r=0. 807 and 0. 792, respectively; both P<0. 01). Conclusion The expressions of PD-1/PD-L1 may play an important role in liver inflammatory injury in rat model of acute liver failure.
