Objective To observe the effect of limbal incision before and after phacoemulsification corneal astigmatism degree.Methods 46 patients with cataract (76 eyes) were randomly divided into two groups.23 cases (40 eyes) in group A received a temporal clear corneal incision phacoemulsification.23 cases (36 eyes) in group B received the upper clear corneal incision cataract ultrasound breast surgery.Results In group A,preoperative corrected visual acuity was (0.13 ±0.10)D,after 3 months of corrected visual acuity was (0.79 ± 0.13)D.In group B,preoperative corrected visual acuity was (0.14 ± 0.11)D,after 3 months of corrected visual acuity was (0.76 ± 0.15)D,the patients after 3 months corrected visual acuity was significantly improved than before treatment (t =4.127,P ＜0.01),the postoperative visual acuity was not statistically significant(t =0.605,P ＞ 0.05).Two groups postoperative corneal anterior surface,surface astigmatism values were gradually reduced,3 months after operation in group A after corneal anterior surface,surface astigmatism value were (0.45 ± 0.24) D,(0.09 ± 0.06) D ; those in B group were (0.52 ± 0.25) D,(0.09 ± 0.07) D,which were significantly lower than 1 week after operation and postoperation(t =2.232,2.128,all P ＜ 0.05).The remaining time two groups of corneal astigmatism value had no significant difference (P ＞ 0.05).Conclusion Temporal clear corneal incision phacoemulsification recovery of visual acuity is better,and less than the above changes of corneal astigmatism corneal incision operation.

Objective To explore the variation and clinical value of the degradation of endothelial glycocalyx in the patients with septic shock. Methods A prospective case control study was conducted. Patients of 18 years or older diagnosed with septic shock and admitted to Department of Critical Care Medicine of Affiliated Hospital of Binzhou Medical University from June 2014 to May 2015 were enrolled. The levels of degradation products, including hyaluronic acid (HA) and heparin sulfate (HS), at 0, 6, 12, 24, 48 hours were determined, while 20 healthy people were enrolled and served as controls. The changes of HA and HS were analyzed in the patients with septic shock. The differences of HA and HS between survival group and death group after 28 days were also analyzed. The relationships between HA, HS and tumor necrosis factor-α (TNF-α), sequential organ failure assessment (SOFA) score, arterial blood lactate (Lac), platelet, albumin were analyzed by Pearson correlation analysis. The receiver-operating characteristic (ROC) curve was plotted to assess the prognostic value of HA and HS for patients with septic shock. Results Thirty-one patients diagnosed as septic shock were enrolled, among whom 17 patients died after 28 days, with a mortality of 54.8%. The levels of HA and HS in patients with septic shock were increased significantly as compared with those of health control group, peaked at 48 hours, and the levels of HA and HS at 48 hours were significantly higher than those at 0 hour [HA (μg/L): 119.47±32.44 vs. 94.84±23.63, HS (μg/L): 72.83±19.03 vs. 58.83±16.63, both P < 0.05]. The levels of HA and HS at 0 hour and 48 hours in death group were significantly higher than those of the survival group [HA (μg/L): 130.42±27.67 vs. 93.29±29.80, 105.14±19.18 vs. 70.82±13.24; HS (μg/L): 67.23±25.01 vs. 39.23±14.58, 79.74±19.84 vs. 56.17±14.53, all P < 0.05]. The levels of HA and HS in patients with septic shock were remarkably positively correlated with the levels of TNF-α, SOFA score, Lac, and platelet, but were remarkably negatively correlated with albumin levels (r value of HA was 0.595, 0.462, 0.545, 0.466, -0.534, respectively; r value of HS was 0.607, 0.468, 0.563, 0.547, -0.455, respectively; all P < 0.05). It was demonstrated by ROC curves that the areas under ROC curve (AUC) of HA and HS at 0 hour and 48 hours for predicting the prognosis of patients with septic shock were 0.881, 0.940 and 0.833, 0.821, respectively, the sensitivities of HA and HS were 87.5%, 100.0% and 83.3%, 81.3%, respectively, and the specificities of HA and HS were 82.6%, 78.3% and 91.3%, 78.3%, respectively. Conclusions The concentrations of degradation products generated by endothelial glycocalyx in the blood of the patients with septic shock are remarkably increased. The elevated levels of the degradation products are closely associated with the severity of septic shock, microcirculation disturbance, and the levels of inflammatory factors.

Objective:To investigate associations of serum low-density lipoprotein cholesterol (LDL-C) with hematoma enlargement, early neurological deterioration (END), and outcome in patients with acute spontaneous intracerebral hemorrhage (ICH).Methods:"A multi-center registration study for spontaneous intracerebral hemorrhage in Inner Mongolia" (registration number: ChiCTR2000029494) database was used to include patients with ICH who completed their first head CT scan within 6 hours after onset, underwent blood lipid examination, CT follow-up within 24 hours of onset, and accurately measured hematoma volume using 3D Slicer software between June 2020 and September 2022. HE was defined as hematoma volume increasing >33% or >6 ml at 24 hours, or ventricular hematoma volume increasing ≥1 ml compared to the baseline. END was defined as an increase of ≥4 in the National Institutes of Health Stroke Scale (NIHSS) score from the baseline or death within 24 hours after onset. The follow-up was conducted at 3 months after onset, and the modified Rankin Scale score >2 was defined as poor outcome. Multivariate logistic analysis was used to determine the independent correlation between LDL-C and HE, END, and outcome. Results:A total of 338 patients with ICH were enrolled, including 206 males (60.9%). LDL-C was 2.39±1.22 mmol/L. Eighty-eight patients (26.0%) developed HE, 67 (19.8%) developed END, and 162 (47.9%) had poor outcome at 3 months. Multivariate logistic analysis showed that after adjusting for confounding factors, there was a significant independent negative correlation between LDL-C and HE (odds ratio 0.312, 95% confidence interval 0.208-0.467; P<0.001) and END (odds ratio 0.408, 95% confidence interval 0.275-0.606; P<0.001), but not with the outcome at 3 months. Conclusion:Lower LDL-C is associated with HE and END in patients with ICH, but not with the outcome.

Objective:To explore the effects of the continuous nursing model on the prognosis, outcome and quality of life of patients with systemic lupus erythematosus (SLE) .Methods:Totally 175 SLE inpatients admitted in the Department of Rheumatology and Immunology in Guangdong Second Provincial General Hospital from January 2016 to September 2019 were selected by convenient sampling and divided into the experimental group ( n=84) and the control group ( n=91) . Patients in the experimental group received continuous nursing care, while patients in the control group received routine care for 3 months The Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) , Systemic Lupus Erythematosus Knowledge Questionnaire (SLEKQ) , MOS SF-36 Health Survey (SF-36) , readmission rate and nursing satisfaction rate were compared between the two groups. Results:After intervention, the patient knowledge and patient's perception of family knowledge scores in the SLEKQ of the experimental group were higher than those of the control group, whereas the SLEDAI-2K score was lower in the experimental group than in the control group, and the differences were statistically significant ( P< 0.05) . After intervention, the scores of all SF-36 dimensions in the experimental group were higher than those in the control group, and the differences were statistically significant ( P < 0.05) ; the readmission rate of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05) ; the nursing satisfaction of the experimental group was higher than that of the control group, and the difference was statistically significant ( P< 0.05) . Conclusions:The implementation of the continuous nursing model can more effectively improve the disease awareness of SLE patients, improve the health-related quality of life, and reduce the readmission rate.

OBJECTIVES: To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN). METHODS: A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021. RESULTS: Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05). CONCLUSIONS Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

Previous studies of Dendrobium officinale on anti-hypertension effect always focused only on the blood pressure,while polysaccharides of D. officinale( DOP) have been traditionally considered as one of the main effective substances. This study aimed to evaluate the effect of ethanol extract from D. officinale( DOE) on blood pressure,Glu and lipid profile in metabolic hypertensive rats induced by comprehensive dietary factors,and elucidate the composition of effective fractions from DOE. A metabolic hypertension model of rat induced by high-sugar,high-fat diet and alcohol drinking was adopted to evaluate the effect of DOE on hypertension and other metabolic disorders. Blood pressure,Glu and lipid profile were detected to find the features and differences of DOE and DOP on metabolic hypertension. Furthermore,DOE was separated with three different common solvents according to the polarity. Along with blood pressure,Glu,UA and lipid profile,hemorheology,oxidative index and aortas structure changes were adopted to evaluate the comprehensive effects of the most effective fractions on metabolic hypertension. Finally,HPLC-DAD-MS was adopted to identify the components of the most effective fraction. The SBP and Glu of models were decreased significantly after administration of DOE and DOP for 6 weeks,while TG in DOE groups also reduced dramatically. The DOE was separated with ether,n-butanol respectively and named NAF,NBF and NCF. SBP,TG,Glu,UA of model rats were decreased significantly after 4 weeks administration with NBF. The level of MDA in serum was down-regulated,while GSH-Px and T-AOC were up-regulated obviously after 12 weeks.And the blood viscosity also obviously decreased,with less collagen deposition of aortas by Masson's trichrome staining. NBF was mainly composed of phenols and flavone C-glycosides,whose aglycone was apigenin,and monosaccharide was connected to C-6 and C-8. Ethanol extract from D.officinale has an positive effect in alleviating hypertension and metabolic disorders in metabolic hypertension. Medium polarity fraction was the effective fraction of alcohol extraction from D. officinale,and mainly composed of phenols and flavone C-glycosides.

OBJECTIVE: To investigate the molecular mechanism underlying the anti-hepatic fibrosis activity of ethyl acetate fraction Dicliptera chinensis (L.) Juss. (EDC) in human hepatic stellate cells (HSCs) in vitro and in a carbon tetrachloride (CCl₄)-induced hepatic fibrosis mouse model in vivo. METHODS: For in vitro study, HSCs were pre-treated with platelet-derived growth factor (10 ng/mL) for 2 h to ensure activation and treated with EDC for 24 h and 48 h, respectively. The effect of EDC on HSCs was assessed using cell counting kit-8 assay, EdU staining, transmission electron microscopy, immunofluorescence staining, and Western blot, respectively. For in vivo experiments, mice were intraperitoneally injected with CCl₄ (2 ° L/g, adjusted to a 25% concentration in olive oil), 3 times per week for 6 weeks, to develop a hepatic fibrosis model. Forty 8-week-old male C57BL/6 mice were divided into 4 groups using a random number table (n=10), including control, model, positive control and EDC treatment groups. Mice in the EDC and colchicine groups were intragastrically administered EDC (0.5 g/kg) or colchicine (0.2 mg/kg) once per day for 6 weeks. Mice in the control and model groups received an equal volume of saline. Biochemical assays and histological examinations were used to assess liver damage. Protein expression levels of α -smooth muscle actin (α -SMA) and microtubule-associated protein light chain 3B (LC3B) were measured by Western blot. RESULTS: EDC reduced pathological damage associated with liver fibrosis, downregulated the expression of α -SMA and upregulated the expression of LC3B (P<0.05), both in HSCs and the CCl₄-induced liver fibrosis mouse model. The intervention of bafilomycin A1 and rapamycin in HSCs strongly supported the notion that inhibition of autophagy enhanced α -SMA protein expression levels (P<0.01). The results also found that the levels of phosphoinositide (PI3K), p-PI3K, AKT, p-AKT, mammalian target of rapamycin (mTOR), p-mTOR, and p-p70S6K all decreased after EDC treatment (P<0.05). CONCLUSIONS EDC has anti-hepatic fibrosis activity by inducing autophagy and might be a potential drug to be further developed for human liver fibrosis therapy.
