Experimental autoimmune prostatitis (EAP)-induced persistent inflammatory immune response can significantly upregulate the expression of N-methyl-D-aspartic acid (NMDA) receptors in the paraventricular nucleus (PVN). However, the mechanism has not yet been elucidated. Herein, we screened out the target prostate-derived inflammation cytokines (PDICs) by comparing the inflammatory cytokine levels in peripheral blood and cerebrospinal fluid (CSF) between EAP rats and their controls. After identifying the target PDIC, qualified males in initial copulatory behavior testing (CBT) were subjected to implanting tubes onto bilateral PVN. Next, they were randomly divided into four subgroups (EAP-1, EAP-2, Control-1, and Control-2). After 1-week recovery, EAP-1 rats were microinjected with the target PDIC inhibitor, Control-1 rats were microinjected with the target PDIC, while the EAP-2 and Control-2 subgroups were only treated with the same amount of artificial CSF (aCSF). Results showed that only interleukin-1β(IL-1β) had significantly increased mRNA-expression in the prostate of EAP rats compared to the controls (P < 0.001) and significantly higher protein concentrations in both the serum (P = 0.001) and CSF (P < 0.001) of the EAP groups compared to the Control groups. Therefore, IL-1β was identified as the target PDIC which crosses the blood-brain barrier, thereby influencing the central nervous system. Moreover, the EAP-1 subgroup displayed a gradually prolonged ejaculation latency (EL) in the last three CBTs (all P < 0.01) and a significantly lower expression of NMDA NR1 subunit in the PVN (P = 0.043) compared to the respective control groups after a 10-day central administration of IL-1β inhibitors. However, the Control-1 subgroup showed a gradually shortened EL (P < 0.01) and a significantly higher NR1 expression (P = 0.004) after homochronous IL-1β administration. Therefore, we identified IL-1β as the primary PDIC which shortens EL in EAP rats. However, further studies should be conducted to elucidate the specific molecular mechanisms through which IL-1β upregulates NMDA expression.

OBJECTIVES:
To investigate the preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and the influencing factors for follow-up compliance.
METHODS:
A multicenter retrospective case-control study was performed for the cases from the multicenter clinical database of 12 units in the Quality Improvement Clinical Research Cooperative Group of Neonatal Severe Hyperbilirubinemia in Jiangsu Province of China from January 2019 to April 2021. According to whether the follow-up of neonatal jaundice was conducted on time after discharge from the department of obstetrics, the neonates were divided into two groups: good follow-up compliance and poor follow-up compliance. The multivariate logistic regression model was used to identify the influencing factors for follow-up compliance of the neonates before admission.
RESULTS:
A total of 545 neonates with severe hyperbilirubinemia were included in the study, with 156 neonates (28.6%) in the good follow-up compliance group and 389 (71.4%) in the poor follow-up compliance group. The multivariate logistic regression analysis showed that low gestational age at birth, ≥10% reduction in body weight on admission compared with birth weight, history of phototherapy of siblings, history of exchange transfusion of siblings, Rh(-) blood type of the mother, a higher educational level of the mother, the use of WeChat official account by medical staff to remind of follow-up before discharge from the department of obstetrics, and the method of telephone notification to remind of follow-up after discharge were associated with the increase in follow-up compliance (P<0.05).
CONCLUSIONS
Poor follow-up compliance is observed for the neonates with severe hyperbilirubinemia after discharge from the department of obstetrics, which suggests that it is necessary to further strengthen the education of jaundice to parents before discharge and improve the awareness of jaundice follow-up. It is recommended to remind parents to follow up on time by phone or WeChat official account.

OBJECTIVES:
To study the survival rate and the incidence of complications of very preterm infants and the factors influencing the survival rate and the incidence of complications.
METHODS:
The medical data of the very preterm infants with a gestational age of <32 weeks and who were admitted to the Department of Neonatology in 11 hospitals of Jiangsu Province in China from January 2018 to December 2019 were retrospectively reviewed. Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants.
RESULTS:
A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25
CONCLUSIONS
The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.

OBJECTIVE:
To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation.
METHODS:
A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation (
RESULTS:
Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly lower rates of cesarean section and use of antenatal corticosteroid (
CONCLUSIONS
For preterm infants with a birth weight less than 1 500 g, the higher intensity of resuscitation in the delivery room is related to lower rate of antenatal corticosteroid therapy, lower gestational age, and lower birth weight. The infants undergoing tracheal intubation or ECRP in the delivery room have an increased incidence rate of adverse clinical outcomes. This suggests that it is important to improve the quality of perinatal management and delivery room resuscitation to improve the prognosis of the infants.

Objective:To explore the value of bedside chest radiograph in the diagnosis and follow-up of severe and critical COVID-19.Methods:Twenty-nine patients with severe or critical COVID-19 were collected from January 23 to February 23, 2020,from four COVID-19 designated hospitals in Guangdong Province. Bedside radiography was taken in all the 29 patients, ranged from 1 to 16 times for each patient. Twenty-seven patients underwent follow-up, and the number of re-examination ranged 1 to 15 times, and the interval of review is 1 to 8 days.The imaging findings of bedside chest radiography and the imaging changes on follow-up chest radiography were analyzed retrospectively.Results:Twenty-nine patients were collected. The radiography showed the lesions involved all more than 3 lung fields. The films showed consolidation shadow in 19 cases, multiple patches of shadow in 23 cases, reticular pattern in 12 cases, strips shadow in 14 cases, interlobar fissure thickening in 18 cases, and "white lung" in 4 cases.The complications included pleural effusion in 4 cases, pneumothorax in 2 cases, mediastinal and subcutaneous emphysema in 1 case. The radiography showed the lesions progressed in 15 cases, with expanded involvement of the lung.The increase of lesion density was found in 6 cases, new lesions were noted in 5 cases, while both of them were found in 4 cases. Nine cases showed improvement, with reduced range and decreased density. Patchy or consolidation shadow turned to strips shadow or articular pattern shadow in 8 cases.There was no significant change in 3 cases with large consolidation shadow.Conclusions:Bedside chest radiography has a good value in the follow-up of severely and critically ill patients with COVID-19, and can provide great help for clinicians to evaluate their condition.

Objective:To investigate characteristic CT manifestations of primary pulmonary diffuse large B-cell lymphoma (DLBCL).Methods:CT images of 14 patients [10 males and 4 females, age (54±2) years old, range 32 to 91] with pathologically-proved pulmonary DLBCL lymphoma were retrospectively analyzed.Plain CT and contrast enhanced CT imaging were performed in all 14 patients. Image characteristics including lesion size, locations and distribution, morphology and margin, density and enhancement degrees, bronchia and lesion surroundings, other thoracic extra-pulmonary manifestations, as well as distant metastasis were analyzed and recorded. The maximal diameter of mass and/or nodules, pre and post-contrast CT values were measured. Among all 14 cases, 8 cases were initially diagnosed as lung carcinoma, 5 cases as infection, one case as lymphoma.Results:Among all 14 primary lung DLBCL cases, there were 10 case with multiple lesions and 4 with single lesion. Masses and/or nodules were found in 12 cases, with the maximum diameter of the lesions as 0.8-8.2 cm, the median value as 5.3 (2.9, 7.8) cm. Two cases showed simple consolidation. The margins of the lesions were clear and smooth in 12 cases, and fuzzy in 2 cases. The density of the lesions on pre-contrast CT was relatively uniform, with mean CT value (35.1±1.0) HU. After contrast, 10 cases displayed mild to moderate homogeneous enhancement, 4 cases showed heterogenous enhancement. The mean CT value of post-contrast images was (61.8±1.5) HU. In arterial phase, the mean CT value was (50.9±1.3) HU. Angiographic sign was found in 9 cases in arterial phase. Of the 14 cases, bronchus was clear and smooth in 5 cases. In 4 cases, bronchus was found slight compressed or stenosis; and 5 cases showed intra-lesion bronchi invasion or occlusion. Interstitial tissue around the lesion was found slightly thickened in 8 cases. The pleura showed unevenly thickened and invaded in 8 cases. Mediastinal or hilar lymphadenopathy and fusion were found in 10 cases, with 3 cases involving mediastinal large blood vessels, and 7 cases displaying infiltrative growth pattern. There were 4 cases with pleural effusion. CT follow-up after treatment in 8 cases showed no distant metastasis (7 cases showed good prognosis, with lesions disappearing after radiotherapy, chemotherapy or surgical resection; 1 case showed progressed with lesion increased after chemotherapy). Six patients abandoned the treatment and discharged from the hospital.Conclusions:Primary DLBCL is a high invasive and malignant entity with certain CT characteristics. The confirmed diagnosis of pulmonary DLBCL depends on pathological results.
