Progress in the pathogenesis and treatment of non suicidal self injury in adolescents / 中国学校卫生

Abstract@#Non suicide self injury is highly common in adolescents, which is seriously threatening their physical and mental health. It is an important predictor of future suicide, and has become a focus of global public health concern. At present, the research on adolescent non suicidal self injury is still in its infancy, and its formation process is complex. The pathogenesis is not completely clear, and the relevant treatment studies are relatively few. The paper expounds the pathogenesis and treatment of the nonsuicidal adolescent NSSI from the perspectives of genetics, neurobiology, neuroimage and social psychology, aiming to provide a theoretical basis for adolescent NSSI prevention and intervention.

Epidemiological characteristics of sexually transmitted diseases in Zhejiang Province from 2018 to 2022 / 预防医学

Objective@#To investigate the epidemiological characteristics of sexually transmitted diseases (STDs) in Zhejiang Province from 2018 to 2022, so as to provide insights into improving STDs prevention and control strategies.@*Methods@#Data of syphilis, gonorrhea, condyloma acuminatum, genital herpes and genital Chlamydia trachomatis infections reported in Zhejiang Province from 2018 to 2022 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. The temporal, spatial and population distribution of STDs were analyzed, and the trends in incidence of STDs were evaluated using annual percent change (APC).@*Results@#A total of 386 770 STDs cases were reported in Zhejiang Province from 2018 to 2022, with mean annual reported incidence of 127.80/105. The mean annual reported incidence from high to low was syphilis (44.11/105), genital Chlamydia trachomatis infections (40.20/105), gonorrhea (24.92/105), condyloma acuminatum (13.32/105), and genital herpes (5.34/105). The incidence of STDs appeared a tendency towards a decline from 2018 to 2022 (APC=-9.332%, P<0.05), with an average annual growth rate of -9.41%. Syphilis (APC=-11.536%, P<0.05), condyloma acuminatum (APC=-7.509%, P<0.05), and genital Chlamydia trachomatis infections (APC=-9.009%, P<0.05) showed a appeared a tendency towards a decline. The top three highest reported incidence were reported in Hangzhou City (185.98/105), Taizhou City (133.85/105) and Lishui City (122.73/105), respectively. The mean annual reported incidence of females was higher than that of males (140.60/105 vs. 117.83/105; P<0.05). Most STDs cases were at ages of 20 to 49 years (265 314 cases, 68.60%). Farmers (118 096 cases, 30.53%), household and unemployed personnel (85 924 cases, 22.22%) were the predominant occupation.@*Conclusions@#The incidence of STDs appeared a tendency towards a decline in Zhejiang Province from 2018 to 2022, with regional differences in incidence. People at ages of 20 to 49 years, farmers, household and unemployed personnel are high-risk populations for STDs.

Comparative immunohistochemical characterization of canine seminomas and Sertoli cell tumors

Primary testicular tumors are the most common causes of cancer in male dogs. Overall, the majority of canine patients should be cured by testicular surgery. However, tumor markers are not well-known in veterinary medicine. We sought to determine using immunohistochemistry whether the combined human testicular tumor markers (placental alkaline phosphatase, OCT3/4, CD30, alpha-fetoprotein, inhibin-alpha, vimentin, c-KIT, and desmin) are expressed in canine seminomas and Sertoli cell tumors (SCTs). We examined 35 canine testicular tumors, 20 seminomas and 15 SCTs. c-KIT was expressed markedly in canine seminomas. Both inhibin-alpha and vimentin were expressed significantly in canine SCTs. The results of this study demonstrate differences and similarities between tumor marker expression of testicular tumors in dogs and humans. All the main markers in current routine use are discussed as well as potential useful markers for benign and malignant tumors, and tumor progression.

Measurement of Colloid Osmotic Pressure in Pregnancy Induced Hypertensive Patients / 대한마취과학회지

BACKGROUND: Pregnancy induced hypertension (PIH) is a common cause of maternal morbidity and death in late pregnancy. Pulmonary edema, although infrequently encountered, may cause death in severe cases of PIH. However, the mechanisms that account for pulmonary edema have not been clarified. Mobilization of peripheral edema, excess fluid intake, myocardial dysfunction, and reduced plasma protein concentration are factors that have been postulated as contributing to the development of pulmonary edema in this syndrome. Colloid osmotic pressure is a principal regulator of capillary fluid exchange. METHODS: In a study of 50 normotensive and severe PIH patients who underwent cesarean section, peripartum plasma colloid osmotic pressure, serum albumin, and total serum protein were compared. RESULTS: Both groups exhibited significantly lower plasma colloid osmotic pressure in the postpartum period than that measured antepartum (p<0.05). The mean antepartum plasma colloid osmotic pressure in severe PIH patients was significantly lower than in normotensive subjects (p<0.05). CONCLUSIONS: We believe that serial COP measurments may be helpful to guide optimal fluid management in severe PIH patients.

Induction of Anesthesia with Low-Dose Midazolam and Thiopental / 대한마취과학회지

BACKGROUND: This study was undertaken to evaluate the hemodynamic response of midazolam-thiopental coinduction technique compared with thiopental or midazolam induction after tracheal intubation. METHODS: 60 patients were divided into 3 groups. Group I thiopental 5 mg/kg induction groups: Group II, midazolam 0.2 mg/kg induction group: Group III 2 mg/kg of thiopental was injected intravenously to each patient 2min after 0.02 mg/kg of midazolam injected. After tracheal intubation, blood pressure and heart rate were measured for 5 minutes at 1 minute interval. Results: There were not significant differences in systolic, diastotic, mean arterial pressure and heart rate in 3 groups. CONCLUSIONS: Low dose midazolam-thiopental coinduction can be a useful method for induction because of same hemodynamic changes as to thiopental or midazolam alone.
