Objective To explore the characteristics of nosocomial infection and its related factors among those very low birth weight infant(VLBWI)for coming up with appropriate preventive measures.Methods Fifty-eight infants with birth weight of 1500 g or below in the hospital from January to June in 2012 were studied actively and retrospectively about their nosocomial infection and related risk factors.Results Thirty-five cases of nosocomial infection occurred among the 58 infants with a prevalence of 60.34%. The mainly pathogenic bacteria was Gram-positive bacteria(88.47%)and mostly,infections presented with lung infections(82.90%) within 21 days after birth.The risk factors included mechanical ventilation,PICC,Apga score<7,fluconazole administration and premature rupture of membranes of VLBWI.Conclusion VLBWI are prone to nosocomial infections,mostly lung infection on day 21 after birth.Management should be strengthened within 3 weeks after birth of VLBWI to minimize infections.Reduction of invasive procedures on children and antibiotic use is particularly important.On the other hand,strengthening the health care in the perinatal period and reducing the incidence of preterm birth cannot be ignored.

This report presented the endemic status of schistosomiasis in the People’s Republic of China at a national level in 2015,and analyzed the data collected from the national schistosomiasis prevention and control system and 457 national schis?tosomiasis surveillance sites. Among the 12 provinces(municipality,autonomous region)endemic for schistosomiasis japonica in P. R. China,5 provinces(municipality,autonomous region),i.e.,Shanghai,Zhejiang,Fujian,Guangdong and Guangxi, had achieved transmission interruption,and 7 provinces of Sichuan,Yunnan,Jiangsu,Hubei,Anhui,Jiangxi and Hunan had achieved transmission control by the end of 2015. There were 453 endemic counties(city,district)covering 252 million peo?ple,specifically including 29 980 endemic villages of 68.61 million people at risk of infection. Among the 453 endemic counties (city,district),75.72%(343/453)and 24.28%(110/453)reached the criteria of transmission interruption and transmission control,respectively. By the end of 2015,it was estimated of 77 194 cases of schistosomiasis,which were decreased by 33.23%compared with 115 614 cases in 2014. No acute schistosomiasis cases were reported in 2015. There were 30 843 advanced schis?tosomiasis cases documented in 2015. A total of 8 736 036 individuals received schistosomiasis examinations and 3 606 individu?als were parasitologically diagnosed,which were decreased by 56.40%compared with 8 270 cases in 2014. An Oncomelania hu?pensis snail survey was performed in 19 965 endemic villages and the snails were found in 5 609 villages,accounting for 28.09%of total villages,with 31 newly detected villages with snails. The snail survey covered an area of 593 572.66 hm2 and snails were found in an area of 173 462.50 hm2,including a newly detected area of 666.04 hm2. No infected snails were found in 2015. A to?tal of 879 373 bovines were raised in the schistosomiasis endemic regions. Of them,526 062 bovines received stool examina?tions,resulting in 315 infected bovines. There were 170 438 schistosomiasis cases receiving drug treatment in 2015,with 2 449 696 individuals undergoing expanded chemotherapy. There were 318 bovines with schistosomiasis receiving drug treatment,with 483 213 bovines undergoing expanded chemotherapy. A total of 144 305.52 hm2 area was subject to snail control by using mollus?cicides,with an actual molluscicide?treated area of 69 221.57 hm2,and 4 572.06 hm2 snail habitats were treated by environmen?tal modification. Based on the data from the 457 national schistosomiasis surveillance sites,the mean Schistosoma japonicum in?fection rate was 0.05% and 0.04% in humans and bovines,respectively. No infected snails were found in all the surveillance sites. The results demonstrate a decline in the endemicity of schistosomiasis in P. R. China and the country reached the criteria of transmission control at the national level. However,the endemic situation of schistosomiasis is unstable in some regions with newly?reached transmission control,and further control and effective surveillance should be strengthened to consolidate the achievements and reduce the endemic situation of schistosomiasis in P. R. China.

Objective:Lung ultrasound (LUS) has been used in the diagnosis of neonatal respiratory distress syndrome(RDS) successfully, but there have been no multicenter prospective studies to verify its reliability or determine how to grade RDS with LUS findings.This study aimed to discuss the necessity and feasibility of using LUS findings to determine RDS grades through a multicenter prospective study.Methods:Every researcher participated in the National Neonatal Lung Ultrasound Training Course and receiving 3-6 months of lung ultrasound system training at the National Neonatal Lung Ultrasound Training Center.Patients between June 2018 and May 2020 who met the RDS ultrasound diagnostic criteria and had full available clinical data were included in this study.The LUS examination was completed immediately after the patients were admitted to the hospital.Some of them also underwent chest X-ray examination.Arterial blood gas analysis was completed immediately before or after the LUS ultrasound examination.RDS grading was performed according to the LUS findings and whether the patient had serious complications.Results:A total of 275 qualifying cases were included in this study, which included 220 premature infants and 55 full-term infants, and the primary RDS occurred in 117 cases (42.5%), and secondary RDS occurred in 158 cases (57.5%). LUS manifestations of RDS patients can be divided into three categories: (1)A ground-glass opacity sign: which could be found among 50 infants when they were admitted to the hospital (that was, at their first LUS examination). Twenty-eight of these infants were considered to have wet lungs and were not sent for special management on admission, but LUS showed typical snowflake-like lung consolidation within 0.5 to 4 hours.Twenty-two of them were given mechanical ventilation with exogenous pulmonary surfactant; Eighteen cases were controlled within 6-12 hours, but the lung lesions became more severe in the other 4 infants (due to severe intrauterine infection). (2)Snowflake-like lung consolidations: the first LUS on admission showed typical snowflake-like lung consolidation involving areas ranging from 1-2 intercostal spaces to 12 lung divisions in 204 cases.Thirty-eight infants among them the lung consolidation only had involvement of 1-2 intercostal spaces at the time of admission; Fifteen of them received invasive respiratory support and recovered within 4-12 hours.Twelve patients received noninvasive respiratory support; Seven of them recovered, while five cases developed severe lung illness.The remaining 11 patients who were not given any form of ventilator support developed severe conditions within 1-4 hours.Thirty of them showed snowflake signs involving 12 lung regions at admission.The remaining 136 patients had lung consolidation degree between the two degree above condition.(3)Snowflake-like sign with complications: Twenty-one patients had severe complications such as pneumothorax, pulmonary hemorrhage or/and persistent pulmonary hypertension of the newborn or large area atelectasis, etc, although snowflake lung consolidation did not involve all lung regions.Conclusion:(1) LUS is reliable and accurate for diagnosing RDS.RDS has the same characteristics on ultrasound for both preterm and full-term infants, both primary and secondary RDS.(2) To facilitate the management of RDS, it is necessary to classify RDS according to the ultrasound findings and the presence of severe complications.(3) Based on the results of this study, it is recommended that RDS can be divided into mild, moderate and severe degrees.The exact standards for grading are as follows: Mild RDS: the early stage of RDS, in which lung consolidation shows as a ground-glass opacity sign on ultrasound; Moderate RDS: lung consolidation shows a snowflake sign on ultrasound, not all of the lung fields are involved; Severe RDS meets one or more of the following criteria: lung consolidation shows as a snowflake sign on ultrasound and all lung regions are involved, or regardless of its degree and extent, lung consolidation has caused serious complications, such as pulmonary hemorrhage, pneumothorax, persistent pulmonary hypertension of the newborn, or/and a large area of pulmonary atelectasis.

Objective To investigate the trends in the disease burden of schistosomiasis worldwide and in China, and Zimbabwe from 1990 to 2019, so as to provide insights into the formulation of the schistosomiasis control strategy in Zimbabwe. Methods Based on Global Burden of Disease Study 2019 (GBD 2019) data sources, the age-standardized prevalence, mortality, disability-adjusted life year (DALY) rate of schistosomiasis were compared in the world, China, and Zimbabwe and the trends in the disease burden of schistosomiasis from 1990 to 2019 were investigated using Joinpoint regression analysis. In addition, the associations between the burden of schistosomiasis worldwide and in China and Zimbabwe from 1990 to 2019 and socio-demographic index (SDI) were examined using Pearson correlation analysis. Results The age-standardized prevalence, mortality, and DALY rate of schistosomiasis were 1 804.95/10⁵, 0.14/10⁵ and 20.92/10⁵ in the world, 707.09/10⁵, 0.02/10⁵ and 5.06/10⁵ in China, and 2 218.90/10⁵, 2.39/10⁵ and 90.09/10⁵ in Zimbabwe in 2019, respectively. The global prevalence, mortality, and DALY rate of schistosomiasis appeared a tendency towards a rise followed by a decline with age in 2019, while the prevalence and DALY rate of schistosomiasis appeared a tendency towards a sharp rise followed by a fluctuating decline in both China and Zimbabwe, and the mortality of schistosomiasis appeared a tendency towards a rise. The age-standardized prevalence [average annual percent change (AAPC) = −1.31%, −2.22% and −6.12%; t = −20.07, −83.38 and −53.06; all P values < 0.05)] and DALY rate of schistosomiasis (AAPC = −1.91%,−4.17% and −2.08%; t = −31.89, −138.70 and −16.45; all P values < 0.05) appeared a tendency towards a decline in the world, China and Zimbabwe from 1990 to 2019, and the age-standardized mortality of schistosomiasis appeared a tendency towards a decline in the world and China (AAPC = −3.46% and −8.10%, t = −41.03 and −61.74; both P values < 0.05), and towards a rise followed by a decline in Zimbabwe (AAPC = 1.35%, t = 4.88, P < 0.05). In addition, Pearson correlation analysis showed that the age-standardized prevalence (r = −0.75, P < 0.05), mortality (r = −0.73, P < 0.05), and DALY rate of schistosomiasis (r = −0.77, P < 0.05) correlated negatively with SDI in the world, China and Zimbabwe from 1990 to 2019. Conclusions The disease burden of schistosomiasis appeared a remarkable decline in China from 1990 to 2019, and the prevalence of schistosomiasis showed a tendency towards a decline in Zimbabwe from 1990 to 2019; however, the mortality and DALY rate of schistosomiasis in Zimbabwe topped in the world. A schistosomiasis control strategy with adaptations to local epidemiology and control needs of schistosomiasis is needed to facilitate the elimination of schistosomiasis in Zimbabwe.

Pulmonary hypertension (PH) is a severe pathophysiological condition characterized by pulmonary artery remodeling and continuous increases in pulmonary artery pressure, which may eventually develop to right heart failure and death. Although newly discovered and incredible treatment strategies in recent years have improved the prognosis of PH, limited types of effective and economical drugs for PH still makes it as a life-threatening disease. Some drugs from Chinese materia medica (CMM) have been traditionally applied in the treatment of lung diseases. Accumulating evidence suggests active pharmaceutical ingredients (APIs) derived from those medicines brings promising future for the prevention and treatment of PH. In this review, we summarized the pharmacological effects of APIs derived from CMM which are potent in treating PH, so as to provide new thoughts for initial drug discovery and identification of potential therapeutic strategies in alternative medicine for PH.
