Objective To evaluate the efficacy and safety of Elvitegravir, Cobicistat, Emtricitabine and Tenofovir Alafenamide Fumarate Tablets in initial treatment of acquired immune deficiency syndrome (AIDS) patients. Methods A total of 80 treatment-naive AIDS patients were selected as research subjects and randomly divided into control group and observation group, with 40 patients in each group. The control group was treated with free antiviral drugs (tenofovir + lamivudine + efavirenz), while the observation group was treated with Elvitegravir, Cobicistat, Emtricitabine and Tenofovir Alafenamide Fumarate Tablets. The CD4⁺ count, human immunodeficiency virus (HIV) viral load, and biochemical indicators were compared between the two groups before treatment and at 3, 6, 9, and 12 months after treatment. The adherence, adverse reactions, and quality of life were also compared between the two groups. Results During the treatment, six patients in the observation group and 9 patients in the control group had no compliance. With the extension of treatment time, the CD4⁺ level in both groups gradually increased, and the HIV viral load gradually decreased (P < 0.05). After 3, 6, 9, and 12 months of treatment, the CD4⁺ levels in the observation group were higher than those in the control group, and the HIV viral loads were lower than those in the control group (P < 0.05). With the extension of treatment time, the levels of alanine aminotransferase, aspartate aminotransferase, urea, creatinine, and uric acid in the control group gradually increased, and the random blood glucose levels after 3, 6, 9, and 12 months of treatment in the control group were higher than those before treatment (P < 0.05). After 3, 6, 9, and 12 months of treatment, the levels of alanine aminotransferase, aspartate aminotransferase, urea, creatinine, uric acid, and random blood glucose in the observation group were lower than those in the control group (P < 0.05). The incidence of adverse reactions in the observation group was 2.94% (1/34), which was lower than 90.00% (36/40) in the control group (corrected χ²=55.718, P < 0.001). With the extension of treatment time, the scores of various dimensions of quality of life in both groups gradually increased, and the scores of various dimensions of quality of life after treatment in the observation group were higher than those in the control group (P < 0.05). Conclusion Compared with the free antiviral drug regimen, Elvitegravir, Cobicistat, Emtricitabine and Tenofovir Alafenamide Fumarate Tablets shows better efficacy in the treatment of AIDS-naive patients, which can significantly increase the CD4⁺ level, and reduce the HIV viral load. Besides, it has high safety, and can significantly improve their quality of life.

Objective:To summarize the situation of dead newborns and their parents after parents gave up treatment, and analyze the reasons and emotional needs of parents who gave up treatment, so as to provide reference for reducing neonatal mortality and negative emotions of parents.Methods:A retrospective study was conducted to collect the data of neonates and mothers who died after giving up treatment reported in Hunan Children′s Hospital from January 2019 to December 2021. The general information, perinatal risk factors, and the incidence of in-hospital diseases were analyzed. Then, semi-structured interviews were conducted with parents of newborns who died after giving up treatment from February to December 2021. Understand why parents give up treatment and their emotional needs.Results:A total of 172 newborns died after giving up were included in the analysis, including 103 males (59.88%) and 74 premature infants (43.02%); Umbilical cord, placenta and amniotic fluid abnormalities were 21 cases (12.21%), 39 cases (22.67%) and 25 cases (14.53%), respectively. Birth asphyxia was 31 cases (18.02%), including severe asphyxia in 18 cases (10.46%); There were 21 (12.21%), 35 (20.35%) and 30 (17.44%) cases of maternal infection in the third trimester, hypertension in pregnancy and diabetes in pregnancy, respectively. The top three causes of death were septicemia (18.02%), congenital malformation (16.86%) and severe pneumonia (10.47%). The main reason why parents give up treatment was that the child′s disease was critical and irreversible, and parents had strong emotional needs for hospice care in their hearts.Conclusions:There are many high risk factors of perinatal death of newborns after giving up treatment. Sepsis is the primary cause of death, and strengthening perinatal health care is fundamental. Parents have a strong demand for hospice care, so it is of practical significance to implement family-centered hospice care model for such special newborns.

Objective:To explore the potential genetic causes of unexplained neonatal encephalopathy.Methods:This retrospective study enrolled 113 infants diagnosed with unexplained neonatal encephalopathy and underwent genetic testing in the Children's Hospital of Hunan Province from January 2019 to May 2021. Perinatal data, clinical manifestations, electroencephalograph, brain MRI findings, genetic information, and prognosis of those patients were analyzed. T-test or Chi-square test were used for data analysis. Results:Of the 113 infants enrolled, 74 (65.5%) were males. The gestational age at birth was (38.6±1.5) weeks, and the birth weight was (2 957±561) g. The most common clinical manifestation was the disturbance of consciousness (83/113, 73.5%), followed by seizures (39/113, 34.5%). There were 38.2% (34/89) of the patients with abnormal brain MRI, and 80.4% (74/92) presented abnormal electroencephalography. Among the 113 infants, 60 (53.1%) had genetic abnormalities, including 48 with single nucleotide variations, eight with copy number variations, and four with chromosome abnormalities. Single nucleotide variations in the 48 patients were classified into syndromic ( n=18, 37.5%), metabolic ( n=16, 33.3%), epileptic ( n=11, 22.9%) and mitochondrial-related genes ( n=3, 6.3%), of which 14 were not included in any database. Among the 103 cases which were successfully followed up until December 31, 2021, 75 (72.8%) had a poor prognosis, including 52 (50.5%) death cases and 23 (22.3%) cases of development retardation. Birth weight and the incidence of seizures in the poor prognosis group were both lower than those in the non-poor prognosis group [(2 876±536) vs (3 254±554) g, t=3.15; 29.3% (22/75) vs 53.6% (15/28), χ2=5.20; both P<0.05], while the incidence of disturbance of consciousness was higher [80.0% (60/75) vs 53.6% (15/28), χ2=7.19, P<0.05]. The proportion of infants with genetic abnormalities in the poor prognosis group was higher than that in the non-poor prognosis group, but the difference was not statistically significant [53.3% (40/75) vs 46.4% (13/28), χ2=0.39, P=0.533]. Conclusions:Genetic abnormality is one of the leading causes of unexplained neonatal encephalopathy. Nucleotide variation is the most common genetic type. Syndromic, metabolic, and epileptic variants are frequently detected in these patients.

Objective:To analyze the significance and factors influencing of CT scan under the modified Valsalva maneuver. Methods:Clinical data of 52 patients with hypopharyngeal carcinoma diagnosed from August 2021 to December 2022 were collected, all patients had calm breathing CT scan and modified Valsalva maneuver CT scan. Compare the exposure effect of the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall, and glottis with each CT scanning method. The effects of age, neck circumference, neck length, BMI, tumor site, and T stage on the exposure effect were analyzed. Results:In 52 patients, 50 patients（96.15%） completed CT scan at once time. The exposure effect of the CT scan under modified Valsalva maneuver in the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall was significantly better than CT scan under calm breathing（Z=-4.002, -8.026, -8.349, -7.781, -8.608, all P<0.01）, while CT scan under modified Valsalva maneuver was significantly worse in glottis than CT scan under calm breathing（Z=-3.625, P<0.01）. In the modified Valsalva CT scan, age had no obvious effect on the exposure effect. The exposure effect was better with long neck length, smaller neck circumference, smaller BMI and smaller T stage. The exposure of postcricoid carcinoma was better than pyriform sinus carcinoma and posterior hypopharyngeal wall carcinoma. But differences were not all statistically significant. Conclusion:The anatomical structure of the hypopharynx was clearly under CT scan with modified Valsalva maneuver, which clinical application is simple, but the effect of glottis was worse. The influence of age, neck circumference, neck length, BMI, and tumor T stage on the exposure effect still needs further investigation.
