ABSTRACT

Objective:To determine the effect of comprehensive measures at reducing mosquito density in residential parking lot, and to provide scientific evidence for exploring a new mosquito density control mode in parking lot. Methods:During April to October in 2018, a package of measures were implemented in the observation group, including designating a full-time staff, combination of property management and mosquito eradication work, continual clean-up of breeding ground, appropriate use of pesticide, education and training of pest control knowledge, and so on. No intervention was conducted in the control group. Then we observed the effect of the above measures in reducing mosquito density. Results:After the implementation of the comprehensive measures, the average adult mosquito density and infant positive rate of ponding mosquitoes in the residential parking lot in the observation group were significantly lower than those in the control group. The mosquito positive rate in rainwater well, sewage well, drainage ditch and intercepting ditch in the observation group was significantly lower than that in the control group. There were no statistically significant difference between the observation group and the control group in the adult mosquito density and the infant positive rate of ponding mosquito in April. Conclusion:Through a package of comprehensive prevention and control measures, mosquito density in the parking lot at residential areas can be effectively reduced. However, there are still some resistances in the implementation process of measures, which need to be constantly optimized to achieve better on-site prevention and control effect.

ABSTRACT

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Wuhan, Hubei Province in December 2019, with severe acute respiratory syndrome (SARS) in 2002 and Middle East respiratory syndrome (MERS) in 2012 are all infectious diseases caused by coronavirus. According to the knowledge of infectious diseases such as SARS and MERS, many patients and health care workers suffered from depression and anxiety during and after the epidemic. In particular, post-epidemic survivors were more likely to suffer from post-traumatic stress disorder (PTSD). Similar conditions could be occurred during and after COVID-19. Therefore, it is also an important task to reduce the prevalence of PTSD after COVID-19 as much as possible and to relieve the tension of infected patients, first-line medical staff, quarantine personnel and so on. Traditional Chinese medicine has unique advantages in the treatment of emotional diseases. Understanding the etiology and pathogenesis of PTSD by theory of traditional Chinese medicine and looking for effective methods to treat PTSD will be helpful to treat PTSD of survivors after COVID-19. It is found that Sini Powder has potential value in the treatment of PTSD by the summary and comparison of the research on traditional Chinese medicine related to the treatment of PTSD. We hope to overcome this epidemic psychologically and spiritually. Therefore, it is considered that Sini Powder can be used as the first choice for relieving emotional diseases of related patients during COVID-19 and treating PTSD of survivors after COVID-19.

ABSTRACT

Objective To observe the effects of Angelica Sinensis Radix on the expression of aquaporin 8 (AQP8) and the levels of AC-cAMP-PKA in colon of blood-deficiency constipation in mice; To identify mechanism of Angelica Sinensis Radix for loosening the bowels to relieve constipation. Methods Sixty Kunming mice were randomly divided into control group, model group, positive medicine group, and Angelica Sinensis Radix high-, medium-, and low-dose groups, with ten mice in each group. Diphenoxylate, acetylphenlyhydrazine and cyclophosphamide were used to establish blood-deficiency constipation mice models. From the 14thday of the experiment, Angelica Sinensis Radix high-, medium-, and low-dose groups were given 16.7, 8.8, and 4.2 g/kg Angelica Sinensis Radix Decoction for gavage. Positive medicine group was given 5.0 g/kg Changtongshu Granules Liquid for gavage. Control group and model group were given equal volume of saline for gavage. The symptoms of blood deficiency constipation were observed and defecation time. Immunohistochemistry, Western blot and qRT-PCR were used to detect the expression of AQP8 protein and mRNA in colon, and the expression of AC-cAMP-PKA in colon was detected by ELISA. Results The mice in the model group developed blood deficiency constipation syndrome; the defecation time was significantly prolonged (P<0.01); the expression level of colonic AQP8 protein and mRNA, AC, cAMP and PKA significantly increased (P<0.05, P<0.01). Compared with model group, the defecation time was significantly shortened in Angelica Sinensis Radix high-, medium-, and low-dose groups; the expression of AQP8 protein and mRNA and the levels of AC, cAMP and PKA were significantly decreased (P<0.05, P<0.01). Conclusion The treatment of Angelica Sinensis Radix for blood-deficiency constipation may be related to adjusting the AC-cAMP-PKA signaling pathways and reducing the expression of AQP8 protein and mRNA.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effects of bifidobacterium on respiratory and gastrointestinal tracts in neonates receiving mechanical ventilation.</p><p><b>METHODS</b>The eligible neonates were randomly assigned into two groups: observed (n=38) and control (n=43). The observed group was given bifidobacteria daily (one capsule per time, for 7 days) by nasal feeding from the next day after mechanical ventilation. Gastric pH, gastric bacteria colonization, feeding intolerance, weight gain, the incidence of ventilator-associated pneumonia (VAP), and the homology between the bacteria isolated from intra-gastric colonization with those causing VAP were observed.</p><p><b>RESULTS</b>The incidence of gastric pH≤3 in the observed group was significantly higher than that in the control group 3, 5 and 7 days after mechanical ventilation (P<0.01). The rate of gastric bacteria colonization in the observed group was significantly lower than that in the control group 5 and 7 days after mechanical ventilation (P<0.01). The incidences of feeding intolerance and VAP in the observed group were significantly lower than those in the control group (P<0.05, P<0.01, respectively). The rate of homology of the bacteria isolated from intra-gastric colonization with those causing VAP in the observed group was significantly lower than that in the control group (P<0.01). There were no significant differences in the weight gain between the two groups.</p><p><b>CONCLUSIONS</b>Bifidobacterium can decrease gastric pH, gastric bacteria colonization and feeding intolerance, thus blocks the infection route "stomach-oropharynx-respiratory tract" indirectly and decreases the incidence of endogenous VAP in neonates receiving mechanical ventilation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the risk factors for intracranial hemorrhage in very low birth weight infants.</p><p><b>METHODS</b>Data from 169 very low birth weight (VLBW) infants (birth weight 1000-1500 g; gestational age 23-36 weeks) were studied retrospectively. Twenty-nine perinatal and postnatal factors were analyzed by Crosstabs Test with SPSS 12.0. A logistic regression analysis was used to identify the risk factors associated with the development of intracranial hemorrhage.</p><p><b>RESULTS</b>Multivariate logistic analysis revealed that rupture of membranes (OR=0.146, 95%CI=0.22-0.964, P < 0.05), 1-minute Apgar score < or = 7 (OR=0.112, 95%CI=0.21-0.591, P < 0.01), pulmonary surfactant therapy (OR=0.110, 95%CI=0.24-0.504, P < 0.01), mechanical ventilation therapy (OR =0.076, 95%CI=0.009-0.668, P < 0.05), mechanical ventilation duration > 72 hrs(OR=0.053, 95%CI=0.007-0.410, P < 0.01), prothrombin time > 20 seconds (OR=4.186, 95%CI=1.606-10.923, P < 0.01), pH value on day 1 of life < 7.25 (OR=0.421, 95%CI=0.179-0.995, P < 0.05) and hyponatremia on day 1 (OR= 0.27, 95%CI=0.077-0.940, P < 0.05) or 2 (OR=2.480, 95%CI=1.053-5.838, P < 0.05) of life were risk factors for intracranial hemorrhage.</p><p><b>CONCLUSIONS</b>1-minute Apgar score < or =7 and mechanical ventilation treatment were leading risk factors for intracranial hemorrhage, followed by abnormal coagulation and electrolytes related to perinatal asphyxia in VLBW infants. These findings can be used to improve the surveillance and prophylaxis measures in VLBW infants at high risk.</p>
