Abstract: Objective　To explore the clinical characteristics of nucleic acid negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicron variant BA. 5.1.3) in Sanya area, and to provide evidence for understanding its clinical characteristics. Methods　A retrospective analysis was performed on 14 neonates with negative nucleic acid delivered by pregnant women who tested positive for SARS-CoV-2 (Omicron variant BA.5.1.3) in Sanya Central Hospital (the Third People's Hospital of Hainan Province) from June 2022 to September 2022 (observation group, n=14). The corresponding nucleic acid-negative newborns delivered by pregnant women detected negative with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) were set as the control group (n=56), and the general data and clinical characteristics of neonates in the two groups were compared. Results　There was no significant difference between the observation group and the control group in pregnancy diabetes, pregnancy induced hypertension, gestational pre-eclampsia, fetal intrauterine distress, premature rupture of membranes (P>0.05); there was no significant difference between the observation group and the control group in terms of sex, gestational age, birth weight, age, mode of delivery, birth Apgar score, heart screening, pulmonary disease, glucose 6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, breast milk jaundice, hemolytic jaundice (P>0.05). The bilirubin level, blue light irradiation cases and the duration of blue light irradiation of the newborns in the observation group at 7 days after birth were higher than those in the control group (P<0.05); the ratio of blood oxygen saturation ≥ 90% in the observation group was lower than that in the control group (21.43% vs 89.29%, P<0.05), and the ratio of blood oxygen saturation occasionally<90% was higher than that in the control group (57.14% vs 10.71%, P<0.05). The ratio of blood oxygen saturation<90% had no significant difference compared with that in the control group (7.14% vs 0, P>0.05), and the ratio of blood oxygen saturation reduced to the required oxygen uptake was higher than that in the control group (14.29% vs 0, P<0.05). Conclusions　The jaundice manifestation of the nucleic acid-negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) in Sanya area is relatively obvious, with blood oxygen saturation easily lower than 90% and even requiring oxygen inhalation in severe cases.

AIM: To investigate the differences in the distribution of SRY-related HMG box 5 (SOX5) gene single nucleotide polymorphisms (SNPs) among stable chronic obstructive pulmonary disease (COPD) patients, COPD with pulmonary hypertension (PH) patients and healthy controls, and to explore the association of the SOX5 SNPs in COPD-related PH.METHODS: From April 2013 to April 2015, 250 patients with stable COPD were enrolled continuous-ly in Ningxia People’s Hospital according to COPD treatment guidelines (2013 edition).All the patients received echocar-diography, and were divided into COPD with PH group [pulmonary artery systolic pressure (PASP)≥50 mmHg, n =103] and COPD without PH group (PASP <50 mmHg, n =147).The healthy persons (matched for age, sex, race and smoking index, n =127) were selected as control group at the same period.Genotyping of SOX5 gene rs10842262 and rs11046966
loci was performed using MassARRAY genotyping system ( Sequenom).Genotype frequencies were calculated.RE-SULTS: Age, sex and smoking index showed no significantly difference between control group and COPD group, neither between COPD with PH group and COPD without PH group.Genotype frequencies of SOX5 gene rs10842262 and rs11046966 loci between control group and COPD group was of significant difference (P<0.05).Genotype frequencies of SOX5 gene rs10842262 and rs11046966 loci showed no significant difference between COPD with PH group and COPD without PH group.CONCLUSION: SOX5 gene rs10842262 and rs11046966 loci may play an important role in COPD, but not in COPD-related PH.

Objective To investigate the causes,consequences and management of injuries to the draining veins after embolization of brain arteriovenous malformations(BAVMs)with ?-n-butyl cyanoacrylate (NBCA).Methods The angiographic imaging data of 189 BAVMs patients who underwent NBCA embolization were studied retrospectively.The status of the draining veins before and after NBCA embolization was observed and compared.The intracerebral hemorrhage(ICH)complications and their relation to their angiographic features were analyzed.Results Twenty-three patients out of 189 patients showed injuries to the draining venous system,including 10 low-grade injury,6 moderate injury,and 7 high- grade injury.Six patients suffered from ICH after embolization,of whom 4 patients were due to injuries of the draining veins(2 moderate and 2 high-grade).In the 3 months follow-up evaluation of 4 patients with ICH, one died,one was in vegetative state,and the other two patients suffered from residual severe or minor (1 patient for each)permanent neurological deficits.Conclusion Our findings suggest that injury of the draining veins is the major cause of ICH and may lead to serious consequences after embolization of BAVMs with NBCA.

Abstract: Objective　To understand the clinical manifestations, symptoms, treatment and recovery of neonates infected with Omicron variant (BA.5.1.3) of SARS-CoV-2, and provide a certain reference for subsequent diagnosis and treatment of related diseases. Methods　The clinical manifestations, epidemiology, auxiliary examinations, and treatment processes of the neonate aged 4-day-old who was community-acquired infection of variant BA.5.1.3 in Sanya was retrospectively analyzed. Results　The neonate's mother was identified as a close contact with patients with coronavirus disease 2019 (COVID-19) one hour before delivery, and tested positive for nucleic acid within 24 hours after delivery. But her breast milk, amniotic fluid, placenta, and umbilical cord were not detected for nucleic acid test after delivery. The nucleic acid test of the neonate was negative within 24 hours after birth. Then he was transferred to the hotel for isolation. Before the transfer, the mother and baby stayed in the same room and ate breast milk but the mother did not wear any mask. The neonate didn't have nucleic acid test on the second and third days of his life, and the nucleic acid test of the neonate was positive on the fourth day, negative on the fifth day, and positive on the sixth day. Then he was transferred to the designated hospital of COVID-19 for treatment. The neonate had no cough, no fever, yellow skin, abdominal distension, general breast feeding, and good reaction. On admission, the laboratory examination showed that blood routine examination and electrolyte were normal, and the myocardial enzyme and liver and kidney functions were normal. The bilirubin was significantly increased (449.3 μmol/L). The nucleic acid test of the neonate was positive and his chest imaging results were normal. The treatment measures were mainly isolation, feeding, blue light fading, close monitoring of vital signs, and antiviral drugs were administered. Jaundice subsided and abdominal distension was relieved after 6 d of treatment, and the treatment process was smooth without complications. Conclusions　The results suggest that the neonates are susceptible to Omicron variant BA.5.1.3 and prone to aggregation. The evidence of vertical transmission is insufficient and the clinical symptoms of neonates infected with Omicron variant BA.5.1.3 are mid, with no involvement of organ damage of the heart, liver, kidney, brain, and other organs.

OBJECTIVETo study the influence of human cytomegalovirus (HCMV) infection on cell cycle and the expression of replication licensing factor Cdt1 in human embryonic lung fibroblastic (HEL) cells and to explore the pathogenesis of HCMV infection.

METHODSHEL cells were synchronized in the G0/G1 phase by the serum starvation method. The synchronized HEL cells were infected with HCMV, and those that were not subjected to HCMV infection were used as the control group. The HEL cells were harvested at 12, 24, 48, 72 and 96 hrs of HCMV infection. The cell cycle of HEL cells was detected by the flow cytometry. The expression of Cdt1 mRNA in HEL cells was determined by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSThe cells in the G1 phase in the control group was significantly more than in the HCMV-infected group 12 and 24 hrs after infection (P < 0.01). The expression of Cdt1 mRNA in the HCMV-infected group was significantly lower 12 and 24 hrs after infection but increased significantly 48 hrs after infection compared with the control group (P < 0.05). The expression of Cdt1 mRNA reached a peak at 12 hrs of infection in the control group, but at 48 hrs of infection in the HCMV-infected group, which markedly lagged behind the control group.

CONCLUSIONSHCMV infection arrests the cell cycle of HEL cells at the G1 phase. HCMV infection makes Cdt1 expression delay. HCMV infection can interfere cell cycle of HEL cells possibly through affecting the expression of Cdt1.

OBJECTIVETo investigate the infection of Helicobacter pylori (Hp) in the liver tissue of patients with chronic liver disease and the association between Hp and chronic liver disease.

METHODSLiver tissue samples were obtained by liver biopsy and surgical resection from 30 healthy subjects, 30 patients with chronic hepatitis, 30 with cirrhosis and 30 with liver cancer. All the samples were confirmed by pathological examination. The gene fragment coding for 16SrRNA were amplified by PCR with sequence analysis.

RESULTSThe PCR product of the 16SrRNA gene was 109 bp in length. Hp 16SrRNA was detected in 18 out of 30 liver biopsy samples from patients with primary cancer (60.0%), in 14 samples from patients with liver cirrhosis (47.0%), and in none of the samples from normal subjects or patients with chronic hepatitis. Sequencing analysis of Hp 16SrRNA gene in the liver tissue showed a 98.8% homology with the gene fragment encoding Hp 16SrRNA.

CONCLUSIONHp is identified in the liver tissue of patients with chronic liver disease, suggesting the possible correlation between Hp infection and hepatocellular carcinoma.
