ABSTRACT

This study aims to develop an improved cell screening system for farnesoid X receptor (FXR) agonists based on a dual luciferase reporter gene system. FXR response element (FXRE) fragments from FXR target genes were cloned and inserted into upstream of firefly luciferase (Luc) gene in the plasmid pGL4-luc2P-Hygro. In combination with the internal reference plasmid containing renilla luciferase, a dual luciferase reporter gene system was developed and used for high throughput screening of FXR agonists. After studying the effects of over-expression of RXR, mouse or human FXR, various FXRE fragments, and different ratio of FXR plasmid amount to reporter gene plasmid, induction efficiency of the screening system was optimized by the known FXR agonist GW4064, and Z factor for the system reached 0.83 under optimized conditions. In summary, an improved cell screening system based on double luciferase reporter gene detection system was developed to facilitate the discovery of FXR agonists, where a new enhanced FXRE element was formed by a superposition of multiple FXRE fragments from FXR target genes, instead of a superposition of traditional IR-1 (inverted repeats-1) fragments.

ABSTRACT

Objective:To study the effects of gender on clinical outcomes of extremely low birth weight infants (ELBWI) and to analyze the risk factors of mortality.Methods:From January 2011 to December 2020, ELBWI (birth weight <1 000 g) admitted to the Neonatology Department of our hospital were retrospectively studied. The infants were assigned into the male group and the female group. Incidences of major complications, survival rate and mortality rate were compared between the two groups. The infants were also assigned into survival group and death group according to their clinical outcomes. Binary multivariate unconditional Logistic regression was used to analyze the risk factors of mortality in ELBWI.Results:A total of 637 ELBWI cases were included. 311 cases were in the male group with a survival rate of 57.9% (180/311) and 326 cases were in the female group with a survival rate of 57.4% (187/326). The incidences of neonatal respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), pulmonary hemorrhage and severe intraventricular hemorrhage (IVH) in the male group were significantly higher than the female group ( P<0.05). Significant increases of survival rate existed for both groups year by year ( P<0.01).No significant differences existed in survival rate, mortality rate of infants receiving proactive treatment and mortality rate of infants withdrawing treatment between the two groups ( P>0.05). Multivariate unconditional Logistic regression analysis showed that withdrawing treatment ( P<0.01) and pulmonary hemorrhage ( P<0.05) were associated with increased risks of mortality. Conclusions:Male ELBWI have higher risks of RDS, BPD and severe IVH than female ELBWI. Withdrawing treatment and pulmonary hemorrhage are common risk factors of mortality for both male and female ELBWI.

ABSTRACT

Objective:Based on Braden scale, combined with local skin temperature and local tissue oxygen saturation as microcirculation indicators, to construct a pressure injury risk prognosis model for severe trauma patients, and develop a visual nomogram.Methods:All the trauma patients in the Emergency Intensive Care Unit (EICU) of a tertiary hospital in Zhejiang Province from June 1, 2020 to August 31, 2020 were selected. The Braden scale was used to assess the risk of pressure injury in the patient and measure the patient’s sacral injury. The skin temperature and blood oxygen saturation at the pressure site were used as indicators for microcirculation evaluation. Multivariate Logistic regression was used to construct a prognostic model and visual nomogram for severe trauma patients with stress injury based on Braden score combined with microcirculation evaluation indicators, and compared with the prediction model constructed by the Braden scale alone. The discrimination degree was judged by the area under the receiver operating characteristic curve. The C index performed internal verification of the model, H-L goodness-of-fit test, and the overall discrimination index to observe and predict the effect of the model.Results:A total of 152 patients were enrolled in this study, of which 33 (21.71%) had pressure injuries. The area under the curve of the Braden scale combined with local skin temperature and local tissue oxygen saturation was 0.866, and the internal verification C index of the model was 0.847. The H-L goodness of fit test result was 8.37 ( P=0.051), indicating that the model had good discrimination and consistency. The overall discrimination index of the model was 0.144 ( P=0.023). Conclusions:The Braden scale combined with local microcirculation indicators to construct a prognostic model of stress injury in severe trauma patients has good discrimination and consistency, and the predictive power of the Braden scale is improved by 14.4%. The construction of a nomogram can provide clinical rapid convenient and reliable forecasting tool.

ABSTRACT

Objective:To evaluate the effect of peer education on improving compliance of cardiac rehabilitation in patients with coronary heart disease.Methods:Totally 64 patients were randomly divided into two groups, namely, the experimental group and the control group with 32 cases in each group. Patients in the experimental group received routine education, nursing, and rehabilitation, plus the peer education treatment, whereas the control group only received routine treatment. The time lasts for 6 months. The compliance of cardiac rehabilitation and the score of China Questionnaire of Quality of Life in Patients with Cardiovascular Diseases (CQQC) were measured after 1 month, 3month and 6 month.Results:After 1, 3, and 6 months of intervention, the compliance of cardiac rehabilitation in the intervention group increased by 18.75%, 21.37%, and 21.88%, respectively, compared with the control group. After the first and third months of intervention, there was a statistically significant difference in the compliance rate of rehabilitation exercise between the intervention group and the control group ( χ2 values were 18.050, 16.946, respectively, P <0.05), and at the sixth month after intervention, the compliance of the two groups of patients with cardiac rehabilitation was not statistically significant ( χ2 value was 6.489, P> 0.05). After 1, 3, and 6 months of intervention, the quality of life scores of the intervention group were (88.68 ± 6.65), (81.90 ± 6.78), and (76.33 ± 5.90) points, and the quality of life scores of the control group were (84.75 ± 4.72), (75.67 ± 5.88), and (74.71 ± 9.47) points. There was significant difference in the scores of the two groups in the first and third months after the intervention ( t values were 2.235, 2.520, respectively, P<0.05); and in the sixth month after the intervention, the difference in the scores of the two groups wasn`t statistically significant ( t value was 1.049, P >0.05). Conclusion:Peer education can improve the compliance of cardiac rehabilitation and the score of CQQC in patients with coronary heart disease in 3 month, but further research is needed to confirm the long-term effect of peer education.

ABSTRACT

Objective To compare the analgesia effects of Oxycodone hydrochloride with Sufentanil in laparoscopic cholecystectomy (LC) anesthesia induction. Method Sixty patients scheduled for elective LC, ASAⅠ or Ⅱ , were randomly divided into two groups (30 in each): Oxycodone group (group O) and Sufentanil group (Group S). Induction of anesthesia: group O: Propofol 1.0 ~ 2.0 mg/kg, Oxycodone 0.3 mg/kg, Vecuronium 0.1 mg/kg. Group S: Propofol 1.0 ~ 2.0 mg/kg, Sufentanil 0.3 μg/kg and Vecuronium 0.1 mg/kg. The value of HR, SBP, DBP of the two groups were recorded in the operation room (T0), after anesthesia induction (T1), 1 min after insertion laryngeal mask (T2), the instant of pneumoperitoneum establishment (T3), separation of the gallbladder (T4), the time of wake up (T5), leave the recovery room (T6). The numeric pain rating scale (NRS) were recorded at T4, T5, 4 hours later (T7), 8 hours later (T8), one day later (T9). Then recorded the wake time and additional analgetic cases. Recorded the adverse reactions. Results The average HR, SBP and DBP fluctuations in the two groups were not more than 20.0 % of the basal values. There was no significant difference in wake time between the two groups. There were 11 cases of patients, the NRS>4, in Sufentanil group requires additional analgesics after they wake up, more than Oxycodone group (P = 0.040). The NRS score was lower in Oxycodone group than group S in T5, T7, T8, T9, but they had no statistically significant difference. There was no significant difference in adverse reactions between the two groups. Conclusion 0.3 mg/kg Oxycodone and 0.3 μg/kg Sufentanil for anesthesia induction of LC, the anesthesia and analgesia effect is good, can satisfy the clinical anesthesia and postoperative analgesic requirements. The analgesic effect of 0.3 mg/kg Oxycodone may be comparable or better than 0.3 μg/kg Sufentanil.

Objective To explore the effect of discharge planning mode on growth and development in prematures.Methods 62 premature cases were randomly divided into the control group and the observation group with 31 cases in each group respectively.The control group accepted routine nursing care,the observation group was given comprehensive detailed discharge planning mode on basis of conventional premature nursing.All the research objects were monitored about the height and body weight,and also the Bayley Infant Development Scale was adopted to evaluate the psychological behavior development when their corrected gestational age was 3,6,12 months respectively.Results The height,weight and Mentality Development Index (MDI),Psychomotor Development Index(PDI) of the prematures in the observation group when their corrected gestational age was 3,6,12 months respectively were all higher than those of the control group.Conclusions Application of discharge planning mode in premature infants is helpful to the physical and mental developmental of them.

ABSTRACT

ObjectiveTo investigate the role of Nav1.7 in dorsal root ganglia (DRG) in a rat model of diabetic neuropathic pain (DNP).MethodsThirty-two female Wistar rats aged 3 months weighing 180-220 g were randomly divided into 4 groups ( n = 8 each):control group ( group C),sham operation group ( group S),DNP group and ProTx- Ⅱ (a selective Nav1.7 blocker) group (group E).Diabetes mellitus was induced by intraperitoneal streptozocin 65 mg/kg.Blood glucose level and mechanical paw withdrawal threshold (MWT)to von Froy filamentstimulation were measured 2 weeks later.DNP was confirmed by blood glucose level ≥ 16.0 mmol/L and MWT decreased by more than 50% of the baseline value.Intrathecal catheter was implanted at L5,6 interspace on day 10 after successful induction of DNP.On day 4 after placement of the intrathecal catheter,ProTx- Ⅱ 10 μg/kg was injected intrathecally in group E,while the equal volume of normal saline was given in groups DNP and S.MWT and never conduction velocity (NCV) were measured 1 h after intrathecal injection.The rats were then sacrificed and DRGs of the lumbar segment (L4-6) were removed for determination of Nav1.7 protein expression (by immuno-histochemistry and Western blot) and Nav1.7 mRNA expression (by RT-PCR).ResultsThe MWT and NCV were significantly lower and the Nav1.7 mRNA and protein expression was significantly higher in groups DNP and E than in group C.ProTx- Ⅱ significantly attenuated the diabetes-induced changes in MWT,but had no effect on NCV and Nav1.7 mRNA and protein expression.ConclusionNav1.7 in DRG is involved in the maintenance of DNP in rats.

ABSTRACT

ObjectiveTo explore the effect of JNK-c-Jun signal pathwayon connexin 43 (Cx43) expression and its role in renal tubular epithelial-myofibroblast transition (TEMT) induced by TGF-β1.Methods Normal rat kidney tubular epithelial cells(NRK-52E) were cultured in Dulbecco's modified eagle medium(DMEM) with 10% fetal bovine serum,then were randomly divided into 3 groups: control group,TGF-β1 group (treated with TGF-β1 10 μg/L),and TGF-β1+SP600125 (selective JNK inhibitor,50 μmol/L) group. The protein expressions of JNK,c-Jun,α-SMA,Cx43 and E-cadherin were assayed by immunocytochemistry and Western blotting.The Cx43mRNA was assayed by RT-PCR.Gap junction intercellular communication(CJIC) was measured by fluorescence recovery after photobleaching assay(FRAP).Results TGF-β1increased the expressions of JNK,c-Jun and α-SMA(P<0.05),reduced the expressions of Cx43 and E-cadherin (P<0.05),and inhibited GJIC of NRK-52E(P <0.05).SP600125 could alleviate the above expressions changes and enhanced GJIC induced by TGF-β1.Conclusion JNK-c-Jun signal pathway induces TEMT ofNRK-52E treated with TGF-β1 viadown-regulation of connexin 43expression and inhibition of GJIC.
