AIM: To explore the feasibility of culturing human umbilical vein endothelial cells ( HUVEC ) on acellular corneal stroma and performing the posterior lamellar endothelial keratoplasty ( PLEK ) treating corneal endothelial decompensation.
METHODS: Thirty New-Zealand rabbits were divided into three groups randomly, 10 rabbits for experimental group, 10 for stroma group and 10 for control group. Corneal endothelial cells were removed to establish animal model of corneal endothelial failure. PLEK was performed on the rabbits of experimental group and stroma group, and nothing was transplantated onto the rabbits of control group with the deep layer excised only. Postoperative observation was taken for 3mo. The degree of corneal edema and central corneal thickness were recorded for statistical analysis.
RESULTS:Corneas in experimental group were relieved in edema obviously compared with that in stroma group and the control group, and showed increased transparency 7d after the operation. The average density of endothelial cells was 2 026. 4±129. 3cells/mm2 , and average central corneal thickness was 505. 2±25. 4μm in experimental group, while 1 535. 6±114. 5μm in stroma group and 1 493. 5±70. 2μm in control group 3mo after operation.
CONCLUSION:We achieved preliminary success in our study that culturing HUVEC on acellular corneal stroma and performing PLEK for corneal endothelial decompensation. HUVEC transplanted could survive in vivo, and have normal biological function of keeping cornea transparent. This study provides a new idea and a new way clinically for the treatment of corneal endothelial diseases.

Objective To explore the prognostic value of ventricular wall motion score (WMS) and left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction (AMI) combined with heart failure (HF) in the recent 12 months Methods We selected hospitalized AMI patients in our department from Jan. 2014 to Nov. 2014. Cardiac ultrasound was performed to detect WMS and LVEF within 48 hours and during the 6?month follow?up period and the occurrence of HF was recorded. Results Totally 127 AMI patients were recruited, including 20 cases combined with HF. The WMS was higher in HF group than those in non?HF group (23.55 ± 3.73 vs 20.11 ± 3.13, P<0.01), while the LVEF in HF group was lower than those in non?HF group (48.77 ± 8.08 vs 56.99 ± 5.17, P<0.01). Multiple logistic regression analysis revealed that WMS and LVEF were both independent predictors of HF in the recent 12 months (P < 0.05). The prediction effect of WMS ROC curve area was 0.81 (P < 0.01) , and LVEF 0.76 (P < 0.05). WMS and LVEF combined assessment area under ROC curve was 0.82 (P < 0.01). Conclusion WMS and LVEF are independent predictors of HF in patients with AMI in the recent 12 months and the combined application of WMS and LVEF can significantly improve the prediction effect.

Objective:To investigate the risk factors for synchronous multiple early gastric cancer (SMEGC).Methods:A retrospective analysis was conducted on data of 390 patients with early gastric cancer, including 353 cases of solitary early gastric cancer (SEGC group) and 37 cases of SMEGC (SMEGC group), who underwent endoscopic submucosal dissection (ESD) in Chinese PLA General Hospital from January 2017 to June 2019. The differences in clinical characteristics (gender, age, body mass index, smoking status, drinking status, family history of gastrointestinal cancer and other cancers, etc.) and pathological characteristics (size, location, morphology, differentiation degree, invasion depth, with or without Helicobacter pylori infection, intestinal metaplasia, ulcers and atrophic gastritis of lesions, etc.) between the two groups were compared by t test, Mann-Whitney U test, Chi-square test, or Fisher′s exact test. Logistic regression (forward LR) was used to screen the independent risk factors for SMEGC. Results:There were no significant differences in the general clinical characteristics between SMEGC group and SEGC group ( P>0.05). Significant statistical differences were observed in the location of lesions ( χ2=8.375, P=0.015), the proportion of atrophic gastritis [48.6% (18/37) VS 23.8% (84/353), χ2=10.710, P=0.001] and the proportion of intestinal metaplasia [81.1% (30/37) VS 43.1% (152/353), χ2=19.452, P<0.001] between the two groups, but there were no significant differences in other pathological characteristics ( P>0.05). Multivariate logistic regression analysis showed that location of lesions in the middle 1/3 of stomach (VS upper 1/3: P=0.036, OR=3.38, 95% CI: 1.08-10.53), in the lower 1/3 of stomach (VS upper 1/3: P=0.049, OR=2.59, 95% CI: 1.00-6.69), presence of intestinal metaplasia ( P=0.001, OR=4.38, 95% CI: 1.77-10.86) and atrophic gastritis ( P=0.043, OR=2.24, 95% CI: 1.04-5.07) were independent risk factors for SMEGC. Conclusion:Patients with early gastric cancer located in the middle or lower 1/3 of stomach, with intestinal metaplasia and atrophic gastritis are prone to SMEGC and should be carefully evaluated and closely followed up after ESD.

Objective To observe the effects of electrical stimulation of the vagus nerve on sepsis-associated encephalopathy, and to explore its possible mechanism. Methods Forty adult male Sprague-Dawley ( SD ) rats were randomly divided into sham group, model group, vagotomy group ( VGX group ), vagus nerve stimulation group ( VNS group ), with 10 rats in each group. The rat model of sepsis was reproduced by injecting lipopolysaccharide ( LPS ) through femoral vein, and rats of sham group were given the same volume of normal saline. The left cervical vagotomy was performed 30 minutes before LPS administration in VGX group, electrical stimulation of the left vagus nerve was initiated 30 minutes after LPS administration in VNS group. The rats in sham group were sacrificed after receiving electroencephalogram ( EEG ) examinations, and brain specimens were taken. The changes in EEG in the other three groups were monitored at 2, 4 and 6 hours after LPS administration, and the δ wave activity percentage was calculated. The blood was collected from abdominal aorta 6 hours after LPS administration, the rats were sacrificed and brain tissue was harvested. The concentrations of tumor necrosis factor-α ( TNF-α) in plasma and brain were measured with enzyme-linked immunosorbent assay ( ELISA ). The histology and ultrastructure changes in the prefrontal cortex in the rats were observed with both light microscope and transmission electron microscope. Results Compared with sham group, the percentage of δ wave on EEG was significantly increased at 2, 4 and 6 hours after LPS administration in model group [ ( 14.52±0.50 )%, ( 16.70±0.85 )%, ( 17.35±0.36 )%vs. ( 12.60±0.46 )%, all P<0.01 ]. It could be deduced that early brain dysfunction occurred in septic rats. Compared with model group, percentage of δ wave on EEG was significantly reduced at 2, 4, and 6 hours in VNS group [ ( 13.10±0.24 )%vs. ( 14.52±0.50 )%, ( 12.81±0.53 )%vs. ( 16.70±0.85 )%, ( 12.61±0.37 )%vs. ( 17.35±0.36 )%, all P < 0.01 ], while there was no such effect in the VGX group. Compared with sham group, the concentrations of TNF-α in plasma and brain were all increased in model group [ plasma TNF-α( ng/L ): 120.11±5.10 vs. 24.37±1.85, brain TNF-α( ng/L ):165.20±6.31 vs. 14.89±0.83, both P<0.01 ]. Compared with model group, the concentrations of TNF-αin plasma and brain were all significantly decreased in VNS group [ plasma TNF-α( ng/L ):46.72±4.90 vs. 120.11±5.10, brain TNF-α( ng/L ):107.95±1.83 vs. 165.20±6.31, both P<0.01 ], while there was no such effect in the VGX group. Light microscope and transmission electron microscope showed that the damage of brain tissue and neurons in model group and VGX group was more obvious, while that in the VNS group was less severe, though not completely disappeared. Conclusions LPS can lead to sepsis-associated encephalopathy in rats. It was shown that electrical stimulation of the vagus nerve can activate anti-inflammatory effect through cholinergic pathway, and improve the cerebral function, and inhibit the development of sepsis-associated encephalopathy by reducing systemic and cerebral inflammatory reaction.
