Objective To explore the changes of blood gas, plasma fibrinogen and D-dimmer levels in neonates with severe hyaline membrane disease (HMD). Methods Forty - three neonates with severe HMD(treated by mechanical ventilation) ,26 neonates with mild HMD( without treated by mechanical venti-lation) and 31 controls were studied. The blood gas,plasma fibrinogen and D-dimmer levels were measured. Results Compared with other two groups, the levels of blood pH, PaO2 and FBG decreased significantly in neonates with severe HMD (P<0.01). The levels of PaCO2 and D-dimmer increased significantly (P<0.01). The blood pH was negatively correlated with plasma D-dimmer level,but it was positively correlated with plasma FBG level in neonates with severe HMD. Conclusion There are coagulation abnormalities in neonates with severe HMD. Hypoxemia and acidosis have close relationship with the coagulation abnormali-ties.

OBJECTIVE:
To investigate the effects of serum from the obesity patients and obesity patients with Diabetic mellitus on toll-like receptor 4/Nuclear factor -κB p65 (TLR/NF-κB) pathway in human THP-1 monocytes and to explore the inflammatory immune response in obesity.
METHODS:
Peripheral serum was isolated from healthy volunteers (the control group), the obesity patients (Ob group) and the obesity patients with diabetic mellitus (the Ob with DM group), respectively, 20 in each group. THP-1 monocytes were incubated with the serum for 48 h. The monocytes and culture supernatant were collected. The phosphorylation level of NF-κB p65 protein in THP-1 monocytes was evaluated by Western blot as well as immunofluorescence assay. The TLR4 mRNA expression was evaluated by RT-PCR. ELISA was used to measure the monocyte chemotactic protein-1 (MCP-1) levels in the culture supernatant.
RESULTS:
In the presence of serum, the obesity group and the obesity with diabetic mellitus group showed the up-regulated phosphorylation level of NF-κB p65 protein and TLR4 mRNA expression in THP-1 monocytes compared with the healthy control group (both P<0.05), and the MCP-1 levels in the obesity patients were up-regulated significantly compared with the healthy control group [healthy control group (26.4 ± 3.9) pg/mL, Ob group (45.8 ± 10.0) pg/mL, Ob with DM group (58.0 ± 15.3) pg/mL; P<0.05]. These parameters were further up-regulated in the obesity patients with diabetic mellitus patients.
CONCLUSION
The serum from the obesity patients or the obesity patients with diabetes can induce monocyte dysfunction, which might be related to the activation of TLR4/NF-κB signaling pathway.

OBJECTIVE:
To investigate the prevalence, risk factors, duration and outcome of delirium in intensive care unit (ICU) patients.
METHODS:
A prospective observational study was conducted for critically ill patients admitted to the department of critical care medicine, the Affiliated Hospital of Guizhou Medical University from September to November 2021. Delirium assessments were performed twice daily using the Richmond agitation-sedation scale (RASS) and confusion assessment method of ICU (CAM-ICU) for patients who met the inclusions and exclusion criteria. Patient's age, gender, body mass index (BMI), underlying disease, acute physiologic assessment and chronic health evaluation (APACHE) at ICU admission, sequential organ failure assessment (SOFA) at ICU admission, oxygenation index (PaO2/FiO2), diagnosis, type of delirium, duration of delirium, outcome, etc. were recorded. Patients were divided into delirium and non-delirium groups according to whether delirium occurred during the study period. The clinical characteristics of the patients in the two groups were compared, and risk factors for the development of delirium were screened using univariate analysis and multivariate Logistic regression analysis.
RESULTS:
A total of 347 ICU patients were included, and delirium occurred in 57.6% (200/347) patients. The most common type was hypoactive delirium (73.0% of the total). Univariate analysis showed statistically significant differences in age, APACHE score and SOFA score at ICU admission, history of smoking, hypertension, history of cerebral infarction, immunosuppression, neurological disease, sepsis, shock, glucose (Glu), PaO2/FiO2 at ICU admission, length of ICU stay, and duration of mechanical ventilation between the two groups. Multivariate Logistic regression analysis showed that age [odds ratio (OR) = 1.045, 95% confidence interval (95%CI) was 1.027-1.063, P < 0.001], APACHE score at ICU admission (OR = 1.049, 95%CI was 1.008-1.091, P = 0.018), neurological disease (OR = 5.275, 95%CI was 1.825-15.248, P = 0.002), sepsis (OR = 1.941, 95%CI was 1.117-3.374, P = 0.019), and duration of mechanical ventilation (OR = 1.005, 95%CI was 1.001-1.009, P = 0.012) were all independent risk factors for the development of delirium in ICU patients. The median duration of delirium in ICU patients was 2 (1, 3) days. Delirium was still present in 52% patients when they discharged from the ICU.
CONCLUSIONS
The prevalence of delirium in ICU patients is over 50%, with hypoactive delirium being the most common. Age, APACHE score at ICU admission, neurological disease, sepsis and duration of mechanical ventilation were all independent risk factors for the development of delirium in ICU patients. More than half of patients with delirium were still delirious when they discharged from the ICU.

Objective:To investigate the impact of recombinant human epidermal growth factor (rh-EGF) on the epithelial recovery and the tear film stability after trans-epithelial corneal collagen crosslinking in patients with progressive keratoconus.Methods:A randomized controlled clinical trail was designed.Consecutive 66 patients (37 males and 29 females) with an average age of (21.27±3.80) years old diagnosed with primary progressive keratoconus and hospitalized in Xiamen Eye Center Affiliated to Xiamen University from October, 2016 to January, 2017 were enrolled and treated with unilateral enhanced transepithelial corneal crosslinking surgery by iontophoresis, and the patients were randomly divided into control group and experimental group according to random number table method, with 33 patients 33 eyes in each group.The eyes in the control group were treated with carboxy-methylcellulose sodium lubricant eye drops and the eyes in the experimental group were treated with rh-EGF eye drops.The ocular surface disease index (OSDI) questionare, slit lamp examination, Schirmer Ⅰ test, corneal fluorescein sodium staining scoring, non-contact tonometry, uncorrected visual acuity, best corrected visual acuity, bulbar conjunctival congestion scoring, lacrimal sevretion test, non-invasive break-up time of tear film (NIBUT), as well as tear meniscus height analysis were performed before surgery, and on day 1, day 3, day 5, day 7, day 14 and day 28 after surgery.This study followed the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xiamen Eye Center Affiliated to Xiamen University (No.2016-ME-003).Results:On day 7 after surgery, the OSDI values were increased in both groups than the preoperative value, while the value in the experimental group was significantly lower than that in the control group ( P<0.05). There were statistically significant differences in the overall corneal epithelial staining score values between the two groups at different time points ( Fgroup=16.701, P<0.01; Ftime=454.418, P<0.01). The corneal epithelial staining score in the experimental group on day 3 and day 5 after surgery were significantly lower than those in the control group (1.79±0.65 vs. 2.70±0.68; 0.91±0.46 vs. 1.55±0.51) (both at P<0.01). The conjunctival congestion score in the experimental group was significantly lower than that of the control group on day 3 and day 5 after surgery (both at P<0.05). There were statistically significant differences in the overall NIBUT values between the two groups at different time points ( Fgroup=13.084, P<0.01; Ftime=34.383, P<0.01). The NIBUT values were significantly decreased rapidly on day 7, day 14 and day 28 after surgery in both groups (all at P<0.01), but gradually recovered.The NIBUT of the experimental group on day 7 and day 14 after surgery were significantly higher than those of the control group ([8.18±2.26]seconds vs. [5.93±2.33]seconds; [9.49±1.95]seconds vs. [7.52±2.27]seconds) (both at P<0.01). No statistical differences were found in the tonometry value, visual acuity, value of Schirmer I test as well as tear meniscus height at any time point before or after surgery between the two groups (all at P>0.05). Conclusions:Recombinant human epidermal growth factor has positive effects in the patients received enhanced transepithelial corneal crosslinking surgery, presenting with promotion of epithelial healing, relief of post-operative discomfort, and the recovery of tear film stability.

Polyphyllin Ⅰ(PPⅠ)and polyphyllin Ⅱ(PⅡ)are the main active substances in the Paris polyphylla.However,liver toxicity of these compounds has impeded their clinical application and the potential hepatotoxicity mechanisms remain to be elucidated.In this work,we found that PPⅠ and PⅡ exposure could induce significant hepatotoxicity in human liver cell line L-02 and zebrafish in a dose-dependent manner.The results of the proteomic analysis in L-02 cells and transcriptome in zebrafish indicated that the hepa-totoxicity of PPⅡ and PⅡwas associated with the cholesterol biosynthetic pathway disorders,which were alleviated by the cholesterol biosynthesis inhibitor lovastatin.Additionally,3-hydroxy-3-methy-lglutaryl CoA reductase(HMGCR)and squalene epoxidase(SQLE),the two rate-limiting enzymes in the choles-terol synthesis,selected as the potential targets,were confirmed by the molecular docking,the over-expression,and knockdown of HMGCR or SQLE with siRNA.Finally,the pull-down and surface plasmon resonance technology revealed that PPⅠ could directly bind with SQLE but not with HMGCR.Collectively,these data demonstrated that PPⅠ-induced hepatotoxicity resulted from the direct binding with SQLE protein and impaired the sterol-regulatory element binding protein 2/HMGCR/SQLE/lanosterol synthase pathways,thus disturbing the cholesterol biosynthesis pathway.The findings of this research can contribute to a better understanding of the key role of SQLE as a potential target in drug-induced hepatotoxicity and provide a therapeutic strategy for the prevention of drug toxic effects with similar structures in the future.

ObjectiveTo establish the identification method of Dalbergiae Odoriferae Lignum(DOL) and its counterfeits by nuclear magnetic resonance hydrogen spectrum(1H-NMR) combined with multivariate statistical analysis. Method1H-NMR spectra of DOL and its counterfeits were obtained by NMR, and the full composition information was established and transformed into a data matrix, and the detection conditions were as follows:taking dimethyl sulfoxide-d6(DMSO-d6) containing 0.03% tetramethylsilane(TMS) as the solvent, the constant temperature at 298 K(1 K=-272.15 ℃), pulse interval of 1.00 s, spectrum width of 12 019.23 Hz, the scanning number of 16 times, and the sampling time of 1.08 s. Similarity examination and hierarchical cluster analysis(HCA) were performed on the data matrix of DOL and its counterfeits, and orthogonal partial least squares-discriminant analysis(OPLS-DA) was used to analyze the data matrix and identify the differential components between them. In the established OPLS-DA category variable value model, the category variable value of DOL was set as 1, and the category variable value of the counterfeits was set as 0, and the threshold was set as ±0.3, in order to identify the commercially available DOL. The OPLS-DA score plot was used to determine the types of counterfeits in commercially available DOL, and it was verified by thin layer chromatography(TLC). ResultThe results of similarity analysis and HCA showed that there was a significant difference between DOL and its counterfeits. OPLS-DA found that the differential component between DOL and its counterfeits was trans-nerolidol. The established category variable value model could successfully identify the authenticity of the commercially available DOL. The results of the OPLS-DA score plot showed that there were heartwood of Dalbergia pinnata and D. cochinchinensis in the commercially available DOL, and were consistent with the TLC verification results. ConclusionThere is a phenomenon that heartwood of D. pinnata and D. cochinchinensis are sold as DOL in the market. 1H-NMR combined with multivariate statistical analysis can effectively distinguish DOL and its counterfeits, which can provide a reference for the identification of them.
