OBJECTIVE: To compare the effects and medication cost of tenofovir disoproxil and entecavir in the treatment of hepatitis B. METHODS: A total of 300 patients with HBV infection selected from our hospital during Sept. 2015-Sept. 2016 were randomly divided into tenofovir disoproxil group and entecavir group, with 150 cases in each group. Tenofovir disoproxil group was given Tenofovir disoproxil fumarate tablet 300 mg orally, qd. Entecavir group was given Entecavir tablet 0. 5 mg orally, qd, for consecutive 48 weeks. HBV-DNA level, negative conversion rate of HBV-DNA, ALT level and ALT normalization rate were compared between 2 groups before treatment, after 24, 48 weeks of treatment. The medication cost-effectiveness ratio and ADR were compared between 2 groups after 48 weeks of treatment. RESULTS: There were no statistical significances in the level of HBV-DNA between 2 groups before treatment, the level of ALT and ALT normalization rate before treatment, after 24, 48 weeks of treatment (P>0. 05). Compared with entecavir group, the level of HBV-DNA in tenofovir disoproxil group after 24, 48 weeks of treatment was decreased significantly (P<0. 05); the negative rate of HBV-DNA in tenofovir group was slightly higher after 24 weeks of treatment, without statistical significance (P>0. 05); the negative rate of HBV-DNA was slightly increased after 48 weeks of treatment (P<0. 05). Negative conversion rate of HBV-DNA and medication cost-effectiveness ratio of ALT normalization in tenofovir disoproxil group were better than entecavir group (P<0. 05). The incidence of ADR in tenofovir dipivoxil group was lower than entecavir group (P<0. 05). CONCLUSIONS: Tenofovir dipivoxil can effectively treat HBV, and its effects and medication cost are both better than entecavir.

Objective:To study the current status of critical neonatal care centers (CNCC) construction and treatment of critically-ill neonates at city- and county-level in Henan Province.Methods:A questionnaire survey was conducted in January 2022 to city- and county-level CNCC in Henan Province. The basic information of CNCC, ward settings, neonatal management in the Department of Obstetrics and the treatment of critically-ill neonates in 2019-2021 were analyzed.Results:A total of 188 questionnaires were sent and 183 (97.3%) eligible questionnaires were analyzed, including 30 from city centers and 153 from county centers. The bed occupancy rate in county centers was significantly lower than city centers (67.3%±24.1% vs. 86.1%±23.2%), and the doctor/bed ratio, doctor/rescue bed ratio and nurse/rescue bed ratio were significantly higher than city centers ( P<0.05). All city centers had set up independent Department of Neonatology and the number is 92.8% (142/153) in county center. For 80.9% (148/183) centers, neonates were managed in the Department of Obstetrics with consultations and referrals to the Department of Pediatrics and 19.1% (35/183) were managed in the Department of Pediatrics/Neonatology. The average number of deliveries and admissions to the Department of Neonatology in both city and county centers decreased year on year during 2019-2021, but the proportion of premature and low/very low birth weight infants treated in these centers increased year on year. During 2019-2021, the top three diseases treated at the city centers were neonatal respiratory distress syndrome, neonatal asphyxia and acute respiratory distress syndrome, while the top three diseases treated at the county centers were neonatal asphyxia, neonatal respiratory distress syndrome and meconium aspiration syndrome. The incidence of sudden infant death syndrome in city and county centers was (10~30)/100,000. Conclusions:The construction of CNCC in Henan Province is facing challenges such as decreased hospital admissions, increased critically-ill neonates, insufficient cooperation between Obstetrics and Pediatrics and waste of resources. Rationally allocated and optimised use of resources to improve the ability to treat critically-ill neonates is warranted.

Objective:To study the influence of periventricular-intraventricular hemorrhage (PVH-IVH) on cerebral blood flow (CBF) of preterm infants in the late postnatal period using arterial spin labeling (ASL) magnetic resonance imaging (MRI).Methods:From January 2023 to June 2023, 65 preterm infants (gestational age <32 weeks, birth weight <1 500 g) who were born in the Department of Obstetrics, Third Affiliated Hospital of Zhengzhou University and transferred to the Neonatal Intensive Care Unit were included in the prospective study.They were examined by the brain MRI and ASL at the corrected gestational age of 35-40 weeks.According to the results of the brain ultrasound within 1 week after birth, they were divided into the mild IVH group (25 cases) and the non-IVH group (40 cases). The CBF values in regions of interest (frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, and basal ganglia) on ASL images were compared.Multiple linear regression analysis was used to analyze the effect of PVH-IVH on CBF values in different ASL regions of interest, including frontal cortex, temporal cortex, parietal cortex, occipital cortex, thalamus, and basal ganglia.Results:Compared with those of non-IVH group, infants in the mild IVH group presented significantly older gestational age [29.0 (28.5, 30.4) weeks vs.28.2 (27.0, 31.0) weeks, Z=-2.398, P=0.016], higher hematocrit (HCT) in the latest examination prior to the brain MRI [29.6(26.4, 32.3)% vs.27.8 (25.6, 30.5)%, Z=-2.155, P=0.031], and larger body weight at the time of examination [2 015.0 (1 930.0, 2 127.5) g vs.1 950.0 (1 900.0, 1 997.5) g, Z=-3.314, P=0.001]. After adjustment for confounding factors of gestational age at birth, latest HCT and weight at the time of examination, the multivariable linear regression analysis showed that CBF values in the frontal lobe (95% CI: -8.367--4.042; P<0.001), temporal lobe (95% CI: -19.077--2.854; P=0.008), parietal lobe (95% CI: -8.344--3.502; P<0.001), occipital lobe (95% CI: -9.446--3.645; P<0.001), basal ganglia (95% CI: -7.543--1.963; P=0.001) and thalamus (95% CI: -8.051--2.372; P<0.001) were significantly lower in infants of the mild IVH group than those of non-IVH group. Conclusions:At the same corrected gestational age, mild IVH is correlated with low CBF values in local cerebral cortex and subcortical gray matter in premature infants.However, the predictive potential of CBF values in long-term neurological prognosis requires further explorations.
