ABSTRACT

Objective:To investigate the effects of terlipressin (TP) combined with norepinephrine (NE) on liver function and prognosis of patients with septic shock.Methods:From June 2018 to December 2019, 96 patients with septic shock and liver function impairment admitted to the ICU of Tianjin First Central Hospital were selected for prospective study. The patients were divided into control group( n=48) and experiment group( n=48) by randomize number table derived by computer. Based on conventional treatment, NE was used in control group, and the low dose continuous infusion of TP combined with NE was used in experiment group. Serial measurements of aspartate aminotransferase (AST), alanine aminotransferase (ALT), serum total bilirubin (TBIL), heart rate and mean arterial pressure (MAP), and blood lactic acid levels were made before the treatment and after the treatment at 24 and 48 hours. The mechanical ventilation time, intensive care unit (ICU) stay, and total length of hospital stay of the two groups were compared, and the 28-day mortality and serious adverse reactions of the two groups was also calculated. Results:The levels of ALT, AST, TBIL, heart rate and blood Lac of the two groups were significantly decreased after the treatment (all P<0.01), and the level of MAP was significantly increased (all P<0.01). Compared with the control group, the levels of 24-hour and 48-hour ALT, AST, TBIL, blood Lac of the experiment group were significantly decreased (all P<0.05), and the 48-hour level of MAP was significantly increased (all P<0.05), but there was no statistically significant difference between the two groups in the levels of 24-hour heart rate and 24-hour MAP (all P>0.05). Besides, there was no statistically significant difference between the two groups in the mechanical ventilation time, ICU stay, total length of hospital stay and the 28-day mortality (all P>0.05). And there were no serious adverse reactions such as avascular necrosis of the fingers and myocardial infraction in the two groups. Conclusions:In the treatment of septic shock, on the basic of adequate fluid resuscitation, continuous intravenous pumping of low-dose TP combined with NE can play a certain protective effect on the live, and the mechanisms of action may be mediated by stabilizing hemodynamics, reducing heart rate, reducing the level of blood Lac and improving liver perfusion, thereby protecting liver function in patients with septic shock.

ABSTRACT

Objective:The epidemiological characteristics and drug susceptibility changes of Pseudomonas aeruginosa(PA) infection in the respiratory tract of children in suzhou were analyzed in order to provide guidance and suggestions for the rational use of antibiotics in this region. Methods:Bacterial culture results of nasopharyngeal secretions from 21 176 children admitted to the Department of Respiratory, Children′s Hospital Affiliated to Soochow University for respiratory tract infections from January 2008 to December 2017 were collected.According to age, season, underlying disease conditions and the presence of intensive care units (ICU) during the hospitalization, these children were divided into different groups.The epidemic characteristics of PA infection were monitored, and changes in PA drug sensitivity were dynamically observed.Results:Among 21 176 nasopharyngeal secretions from children with respiratory tract infection, 191 cultures were detected with PA, and showing a positive detection rate of 0.90% (191/21 176 cases). The annual detection rate was different.The highest detection rate was 2.24% (50/2 234 cases) in 2009 and the lowest was 0.41% (9/2 207 cases) in 2014.The detection rate of PA in children with in >6 months to 1-year-old group was the highest (1.52%, 53/3 497 cases), and the lowest was 0.57%(11/1 934 cases) in the >5-year-old group.The detection rates of PA in spring, summer, autumn, and winter were 1.11% (60/5 420 cases), 1.21% (61/5 046 cases), 0.81% (46/5 670 cases), and 0.48% (24/5 040 cases), respectively.The difference of PA detection rates between summer (the highest rate) and the winter (the lowest rate) was statistically significant ( χ2=18.611, P<0.001). Among the 21 176 children, 18.89% (4 000/21 176 cases) had basic diseases, and the PA detection rate in such kind of patients was 1.28% (51/4 000 cases), which was higher than that in patients without basic diseases (0.82%, 140/17 176 cases). The PA detection rate in the ICU group was 4.41% (15/340 cases), which was significantly higher than that in the general group (0.84%, 176/20 836 cases) ( χ2=7.678, 47.623, all P<0.05). There were no strains susceptible to Ampicillin, Ampicillin/Sulbactam and compound Sulfamethoxazole, and no strains susceptible to Ceftriaxone from 2010 to 2017.The susceptibility rate to Imipenem was low from 2012 to 2015, and the lowest was only 66.7% in 2014.The sensitivity rate to Aztreonam fluctuated significantly from year to year.Strains were all highly sensitive to Piperacillin, Piperacillin Tazobactam, Ciprofloxacin, Levofloxacin, Gentamicin, and Tobramycin. Conclusions:PA infection is prone to occur in young children with basic diseases and relatively severe illness.Summer is a high-incidence season.PA is generally highly resistant to commonly used antibiotics.

ABSTRACT

Objective To obtain a non-invasive subclinical hypothyroidism ( SCH) mouse model, and to explore microRNAs profile related to lipid metabolism in the model mice. Methods C57BL/6 male mice (8 weeks) were treated with methimazole ( MMI, 0. 08 mg/kg BW/d) to construct SCH mouse model. MicroRNAs profiling analysis was performed by real-time quantitative polymerase chain reaction ( qRT-PCR) . Results Compared with the control group, the serum thyroid stimulating hormone ( TSH ) in subclinical hypothyroidism group increased significantly (P>0.01), while the serum free thyroxine(FT4) level did not show significant difference between the two groups (P>0. 05), which was in line with the diagnostic criteria of SCH. SCH mice was accompanied by dyslipidemia and liver lipid metabolism disorders. Four lipid metabolism related miRNAs, miR-33, miR-122, miR-199a-5p, and miR-375 in the liver of SCH mice were significantly decreased compared with those of control ( P>0. 05). Conclusion The noninvasive SCH model generated by MMI and miRNAs profile provide an animal model and a molecular basis for the study of SCH related lipid metabolism disorders.

ABSTRACT

OBJECTIVE:To observe therapeutic efficacy and safety of paroxetine combined with flupentixol melitracen in the treatment of post-stroke major depressive disorder(PSMDD). METHODS:120 PSMDD patients were randomly divided into group A(40 cases),group B(40 cases)and group C(40 cases). All patients received routine stroke treatment;group A was additionally given Paroxetine hydrochloride enteric-coated sustained-release tablet 25 mg orally,once a day;group B was additionally given Flu-pentixol melitracen tablet 20 mg orally twice a day;group C was additionally given Paroxetine hydrochloride enteric-coated sus-tained-release tablet (same usage and dosage as group A)+flupentixol melitracen (same usage and dosage as group B). Three groups were treated for 28 d. Clinical efficacies of 3 groups were observed as well as NIHSS,ADL,HADM,SS-QOL score,hos-pitalization stay and the occurrence of ADR. RESULTS:Total response rate of group C was significantly higher than those of group A and B;hospitalization day was significantly less than those of group A and B,with statistical significance(P0.05). There was no statistical significance in the incidence of ADR among 3 groups (P>0.05). Before treatment,there was no statistical significance in NIHSS,ADL,HADM,SS-QOL score among 3 groups(P>0.05). After 10,28 d of treatment,NIHSS,HADM,SS-QOL score of 3 groups were significantly lower than before, above indexes were decreased gradually as time,and the group C were lower than the group A and B;ADL score of 3 groups were significantly higher than before,this index was increased gradually as time,and the group C were lower than the group A and B with statistical significance (P0.05). CONCLUSIONS:Based on routine treatment,paroxetine combined with flupentixol melitracen in the treatment of PSMDD can relieve neurologic function injury,improve depression condition and the quality of life without increasing the occurrence of ADR.

ABSTRACT

Objective To verify the relationship between transforming growth factor-β1(TGF-β1) and interleukin-10 (IL-10) in breast milk and allergic diseases development in infants. Methods Totally 191 mothers (99 allergics and 92 controls) and their full-term newborns participated in this prospective study on development of children atopy. Maternal blood, cord blood, colostrum and mature milk were assayed for TGF-β1 and IL-10 by enzyme-linked immunosorbent assay. Infants underwent pediatrician evaluation for allergic diseases at six months old. Concentrations of TGF-β1 and IL-10 from allergic and non-allergic mothers and prevalence of allergic diseases of infants were compared. Results The level of IgE in allergic mothers was 30 750 IU/L(6600-410000 IU/L),lower than that in non-allergic mothers[50000 IU/L(7100-610000 IU/L)](Z=-3. 444,P=0. 001).No difference in the concentration of TGF-β1, IL-10 and IgE in mature milk was observed between allergic and non-allergic mothers. TGF-β1, IL-10 and IgE levels in colostrum of allergic mothers were 2300 pg/ml(620-7000 pg/ml), 12. 8 pg/ml(7.5-560.0 pg/ml)and 7000 IU/L(5100-56000 IU/L),significantly higher than those in non-allergic mothers[1830 pg/ml(1240-9400 pg/ml), 11. 1 pg/ml (7. 2-630.0 pg/ml)and 6700 IU/L(5200-35000 IU/L)] (Z=-2. 215, -2. 730 and -2. 706,P<0.05).In both allergic and non-allergic mothers, TGF-β1 and IL-10 levels in cord blood were higher than those in maternal blood, while IgE was lower. TGF-βl and IL-10 and IgE levels in colostrum were higher than mature milk(P<0.05). At six months old, the prevalence of allergic diseases of infants from allergic mothers(59. 6%, 59/99) was significantly higher than those from non-allergic mothers (21. 7%, 20/92)(x2= 28. 177, P= 0. 000). The prevalence of allergic diseases of infants who completed two weeks' colostrum-fed after birth (44.5 %, 73/164) was significantly higher than those who did not (22.2%,6/27)(x2 =4. 749,P-=0. 029). Conclusions High concentration of TGF-βl and IL-10 in colostrum does not show any protective effect against allergic diseases in infants. The prevalence of allergic diseases of colostrum-fed infants is significantly higher than non colostrum-fed infants, showing that colostrum-fed might play a role in allergic diseases development.

ABSTRACT

AIM: To explore the molecular mechanism of asthenospermia(AST) by preliminary screening of nucleotide sequences from the ND3 and ND4L genes of mitochondrial DNA(mtDNA). METHODS: Samples from 50 AST patients and 42 age-matched normal controls were collected according to the WHO criteria. Density gradient centrifugation was applied to separate spermatozoa with different vigor. The ND3 and ND4L genes of mtDNA were amplified and sequenced directly from the extracted genomic DNA from AST patients and normal controls. The sequences were compared with revised Cambridge Reference Sequence(rCRS) to analyze the variants. RESULTS: A total of 22 nucleotide variations were found in ND3 and ND4L genes of mtDNA in asthenospermia group and control group. G10320A, A10398G and T10609C were missense mutations, while A10157G and A10313C were the reported for the first time in this study. Haplotype N in patients with AST(33/50) was higher than that in control group(14/42, P<0.05), and haplotype R9 in patients with AST(15/50) was also higher than that in control group(4/42, P<0.05) through genetic testing of ND3 gene. Rates of sperm progressive motility of haplotype F1, F2 and R9 were significantly lower than those of haplotype M and M rest. Two haplotype differences, haplotype M and N, were found in the same AST patient's spermatozoas which had different vigor. Haplotype M had stronger vigor, while haplotype N had lower vigor. By sequencing ND3 gene of mtDNA from 50 AST patients, we detected G10310A heteroplasmic mutation in 2 specimens of asthenospermia with poor and moderate motility spermatozoa, respectively. No mutation occurred in good motility spermatozoa. CONCLUSION: Haplotype of mitochondrial may have some correlation with sperm motility. The nt10398G-10400T polymorphisms may have benefit for sperm motility, whereas the mutation in nt10310A may impair sperm motility.

ABSTRACT

Objective To assess the value of magnetic resonance angiography (MRA) and arterial proton spin labeling (ASL) in the internal carotid artery transient ischemic attack. Methods According to TIA seizure frequency, 58 patients clinical diagnosed as TIA were divided into single group (n=12) and the frequent group (n=46). All patients underwent MRA and ASL, then intracranial arterial stenosis and cerebral perfusion were evaluated. Results Vascular stenosis with abnormal ASL were detected in 33 (71.74%) of 46 frequent TIA patients and 1 (8.33%) single TIA patient. The incidence of vascular stenosis with abnormal ASL was higher in frequent TIA than that in single TIA (P<0.05). Conclusion Vascular stenosis with perfusion abnormality is one of the most risk factors of TIA frequent seizures. Combination of MRA and ASL can make judgment for stenosis and abnormality of cerebral blood flow, being helpful to understand the onset causes and prognosis of TIA.

ABSTRACT

0 05).CONCLUSION:Na +-K +-ATPase is not sensitive to ischemic damage,but sensitive to reperfusion damage.Like hypothermia,scopolamine can protect Na +-K +-ATPase activity in the cerebral cortex during postischemic reperfusion,but hypothermia has no cooperating effect on scopolamine.
