ABSTRACT
We aimed to analyze the clinical data of 10 patients (6 male and 4 female) with Fabry disease (FD). The mean age of the patients was (28.80±9.27) years. Seven patients had classical FD and three had delayed onset FD. Among the 10 patients, six had skin involvement and cutaneous angiokeratoma; five had hypohidrosis or anhidrosis; nine had intermittent neuralgia; and three had supraorbital ridge protrusion, forehead bulge, and lip thickening. Five patients had proteinuria, including one with chronic kidney disease stage 3 and one with chronic kidney disease stage 5. Cardiac involvement occurred in three patients, two had myocardial hypertrophy and one had valvular insufficiency. The activity of galactosidase decreased in seven patients (2.80-1.55 μmol·L -1·h -1). Plasma deacetyl-GL-3 was elevated in all 10 patients(3.12-120.00 ng/ml). Three patients underwent renal biopsy, wherein two cases of focal segmental glomerulosclerosis and one of mesangial proliferative glomerulonephritis was found. A large number of myeloid and zebra bodies were found in the podocytes in three patients, including a small number of myeloid and zebra bodies in the renal tubular epithelial cells in one patient with occasional zebra bodies in the renal interstitium. Nine patients had GLA gene mutations. One patient was c.102T>A, a de novo mutation. Four patients were treated with agalsidase α injection (0.2 mg/kg, intravenous infusion every 2 weeks), and their prognosis was good. FD has various clinical manifestations and multi-system involvement, which requires multidisciplinary cooperation. Detection of galactosidase activity, plasma globotriaosylsphingosine, and GLA gene mutation can help for accurate diagnosis.
ABSTRACT
Objective:To investigate the efficacy of pixel 2 940 nm erbium laser combined with vitamin B12 in the treatment of acne sunken scar.Methods:From July 2017 to June 2019, 96 patients with acne sunken scar were treated in the Department of Burn and Plastic Surgery of the Second People's Hospital of Jiaozuo City, Henan Province.

ABSTRACT
Objective:To investigate the risk factors of acute gastrointestinal failure in patients with traumatic brain injury(TBI).Methods:A retrospective analysis of 297 patients admitted to the Rugao Hospital Affiliated to Nantong University for traumatic brain injury from March 2018 to March 2020 was performed. Multivariate Logistic regression analysis was used to test the risk factors of acute gastrointestinal failure in patients with traumatic brain injury.Results:Of the 297 patients with TBI, 92 (30.98%) had acute gastrointestinal failure, of which 56 (18.86%) were acute gastrointestinal injury(AGI) Ⅲ and 36 (12.12%) were AGI Ⅳ. Multivariate Logistic regression analysis showed that female, low Glasgow Coma Scale (GCS) scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection were independent risk factors for acute gastrointestinal failure in TBI patients ( P<0.05). The length of ICU stay in the acute gastrointestinal failure group was significantly higher than that of the non-acute gastrointestinal failure group: (18.5 ± 2.6) d vs. (6.3 ± 1.2) d, and the incidence of good prognosis was significantly lower than that of the non-acute gastrointestinal failure group: 60.87%(56/92) vs. 80.49(165/205), the differences were statistically significant ( P<0.05). Conclusions:That female, low GCS scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection are independent risk factors for acute gastrointestinal failure in TBI patients
ABSTRACT
Objective To explore the influence of dexmedetomidine on blood gas and inflammation cytokines in patients with one-lung ventilation (OLV).Methods Sixty-two patients undergoing radical resection of pulmonary carcinoma were divided into observation group and control group in sequence,31 cases in each group.All patients treated with intravenous sufentanil 0.3-0.5 μg/kg,propofol 1.5-2.5 mg/kg,midazolam 0.5 mg/kg and rocuronium 0.9 mg/kg for induction of anesthesia;intravenous infusion of propofol 6-8 mg·kg-1 ·h-1 and remifentanil 0.1-0.5 μg·kg-1 ·min-1,intermittent intravenous injection of cisatracurium for anesthesia maintenance.The patients in the observation group were given 1μg/kg loading dose dexmedetomidine 10 min before anesthesia induction (infusion in 10 min),maintaining at 0.5 μg·kg-1 ·h-1 until 30 min before the end of surgery.The patients in the control group were given the same amount of saline as a control.The blood gas analysis index,pH,partial oxygen pressure (PaO2),CO2 partial pressure (PaCO2) and such inflammation cytokines as tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) at OLV (T0),after OLVlh (T1),the end of OLV (T2) were respectively tested,the dosage of propofol in the two groups were recorded.Results The dosage of propofol in observation group was significantly lower than that in the control group (P<0.05);pH declined in the two groups (P<0.05),but the difference had no statistical significance;PaO2 was rising then declined in the two groups (P<0.05),but it was significantly higher in the observation group than in the control group(P<0.05);PaCO2 in the two groups increased gradually(P<0.05),it was significantly lower in the observation group than in the control group (P<0.05);The serum TNF-α,IL-6 in the two groups showed a trend of increasing (P<0.05),it was significantly lower in the observation group than in the control group (P<0.05).Conclusion Dexmedetomidine can maintain blood gas stability and reduce inflammation caused by single lung ventilation.

ABSTRACT
Objective To investigate the effects of angiotensin Ⅱ (Ang Ⅱ) or high glucose on the toll-like receptor 4 (TLR4) expression,inflammatory cytokines and fibrotic factors in human tubular epithelial cells (HK-2),revealing the innate immune-related pathogenesis of diabetic nephropathy (DN) which may have clinical implications.Methods Three TLR4 siRNA sequences were designed and synthetized.After transfection,the most effective siRNA was selected to use for further expriments.The experiment consisted of 2 parts.Part 1:Cells were divided into three groups:normal-glucose group (NG,5.5mmol/L glucose),mannose group (M,5.5 mmol/L glucose + 19.5 mmol/L mannose),High-glucose group (HG,25 mmol/L glucose),preliminary validated the effects of high glucose and high osmotic pressure.Part 2:Cells were divided into seven groups:NG group,HG group,Ang Ⅱ group,Ang Ⅱ + negative group,HG+ negative group,Ang Ⅱ + siRNA group and HG+ siRNA group.Real time PCR was used to analyze the mRNA expression of TLR4,myeloid differentiation factor 88 (MyD88),heat shock protein 47 (HSP47).Western blotting was used to observe the protein expression of TLR4,MyD88,HSP47,NF-κB,type Ⅳ collagen (ColⅣ).ELISA was used to detect the expression of monocyte chemotactic protein-1 (MCP-1) and interleukin-6 (IL-6).Results Compared with NG group,TLR4,MyD88,HSP47 mRNA and TLR4,MyD88,NF-κB,ColⅣ,HSP47 protein were highly expressed under high glucose or Ang Ⅱconditions (P < 0.01),and the expression levels of MCP-1 and IL-6 also increased significantly (P < 0.01).Compared with HG or Ang Ⅱ group,the above indicators were obviously inhibited in the TLR4 siRNA groups (P<0.01).Comparison between blank vector transfected groups and HG group as well as Ang Ⅱ group indicated no statistic significance (P > 0.05).Conclusions Both Ang Ⅱ and high glucose stimulate TLR4 expression,which result in the up-regulation of inflammatory and fibrotic factors in HK-2.Specific target of TLR4 gene silencing can block the TLR4 pathway that is activated by high glucose and Ang Ⅱ,and thus reduce the inflammatory and fibtogenic factors' release.TLR4 signal is the common innate immune response pathway which induces the release of inflammatory and fibrotic factors in HK-2 under high glucose or high angiotension conditions.

ABSTRACT
Objective To test the effect of Undaria pinnatifida soluble dietary fiber on endothelial function in hyperlipidemic rats. Method Forty rats were divided into 4 groups(n=10) :control group,hyperlipidemic model group,low dose dietary fiber-treated group(5%) ,high dose dietary fiber-treated group(10%) . After treatment for 8 w. Endothelium-dependent vasorelaxation in isolated aortic rings,the content of plasma malondialdohyde(MDA) ,nitric oxide(NO) and endothelin-1(ET-1) were determined. The protein expression of endothelial NO synthase(eNOS) was measured by Western blotting. Results Undaria pinnatifida soluble dietary fiber treatment significantly decreased MDA and ET-1 level. It also significantly improved endothelial function and plasma NO level concomitantly with unregulation of the expression of eNOS protein. Conclusion In hyperlipidemic rats Undaria pinnatifida soluble dietary fiber could improve vascular endotheliual function,which might be explained by its action to decreasing plasma ET-1 level and increased NO production.
