AIM To examine the effect and mechanism of emodin on intestinal movement of constipation model. METHODS The movement of charcoal powder and the absorption of D-xylose into serum were observed. The electrical p otential difference(PD) related to Na + and glucose transport was measured across the wall of rev erted intestinal sacs. RESULTS Emodin 0 1, 0 2 g?kg -1 incr eased markedly the rate of charcoal powder moving and inhibited the absorption of D-xylose into serum. Emodin 0 2, 0 4, 0 8 and 1 6 g?L -1 decreased PD when ther e was glucose. However, emodin had little effect when glucose was free. CONCLUSION Emodin promotes intestinal movement and this effect is related to Na +,K +-ATPase.

Purpose To investigate the clinicopathologic characteristics, differential diagnosis, treatment and prognosis of differentia-ted-type vulvar intraepithelial neoplasia ( dVIN) . Methods Clinicopathologic findings and immunophenotypes of 6 cases diagnosed as“dVIN” were retrospectively analyzed, and the relevant literatures were also reviewed. Results 6 patients were all female ranged 53~80 years old with mean age of 62 years old. Clinical aspects included leukoplakia vulvar, pruitis, irritation, pain, ulcer and so on. The histopathological features were hyperplasia of basal and parabasal layer with elongation and anastomosing reteridges. Cells were marked atypia with obvious nucleoli, atypical mitosis, and dyskeratosis. In the middle and surface layer, cells were well differentiated with pronounced intercellular bridges, and eosinophilic cytoplasm, hyperkeratosis and parakeratosis. Oedema and band of infiltration of chronic inflammatory cells of subepidermal could been seen. Immuohistochemistry showed the expression rates of p53 and p16 in totally 6 cases were 83. 3% (5/6), 0 (0/6), respectively. The Ki-67 index was more than 90% in basal and parabasal cells. Four patients were followed up ( mean follow-up 17 months, range 6~36 months) , one patient died at 9 months later after surgery, another patient recurred at 6 months later after surgery, both of the 2 cases were all with invasive lesions after resection, and the rest two cases had no recur in 18 months and 36 months after surgery, respectively. Conclusion dVIN is a high grade squamous intraepithelial lesions of vulvar with low incidence rate, but had more risk of progression. p53, p16 and Ki-67 stain were useful in the diagnosis of dVIN.

Objective:To analysis the risk factors and safety of administration of norepinephrine (NE) via peripheral vein line (PVL) in patients with septic shock.Methods:A single-center retrospective study was conducted. According to the Lanzhou University Second Hospital information system (HIS) and nursing adverse events report cards, patients with septic shock administrated with NE via PVL to correct the hypotension from January 1st 2015 to December 31st, 2019 were enrolled. The patients' general information, placement location of peripheral venous catheter and venousneedle type, characteristics of NE usage and patient general condition when extravasation occurred were collected. The univariate analysis and Logistic regression were used to analyze risk factors associated with extravasation. Also, the receiver operator characteristic curve (ROC curve) was drawn, and the predictive value of risk factors for extravasation was analyzed.Results:A total of 1 022 cases with NE were enrolled. After a preliminary screening, a total of 910 cases with NE were used to correct low blood pressure, including 116 cases of peripheral venous infusion. The average age was (52.91±18.69) years old, with majority of female (77 cases, 66.4%). Basic diseases were mainly chronic obstructive pulmonary disease (COPD, 100 cases, 86.2%), followed by hypertension(91 cases, 78.4%), coronary heart disease (87 cases, 75.0%), type 2 diabetes (74 cases, 63.8%) respectively, the primary disease was septic shock in 109 cases (94.0%). A total of 147 peripheral venous catheters were inserted, and the most common site of puncture was the forearm [78.9% (116/147)], followed by the hand [12.2% (18/147)] and the median cubital vein [8.8% (13/147)]. 89.9% of the needles were 20 G in diameter, and 75 cases (64.7%) were converted to central venous catheters (CVC) during subsequent treatment due to continuous infusion of NE. Six patients (5.2%) had extravasation, the median time of extravasation was 29 (23-39) hours, and the median time of NE was 23 (11-53) hours, including 2 patients with an infusion concentration of 60 mg/L and 4 patients with an infusion concentration of 120 mg/L.The infusion speed was 0.5-1.0 μg·kg -1·min -1, and the average speed of infusion was (0.75±0.04) μg·kg -1·min -1 when extravasation. Univariate and binary Logistic regression analysis showed that the risk factors related to the occurrence of extravasation included: ① patient factors: the presence of basic diseases, hypertension [odds ratio ( OR) = 3.11, 95% confidence interval (95% CI) was 3.09-3.12, P = 0.001] and edema ( OR = 1.79, 95% CI was 1.32-2.99, P = 0.032). ② Factors of infusion fluid itself: long-term (> 24 hours) infusion ( OR = 2.91, 95% CI was 1.04-5.96, P = 0.040), infusion concentration > 60 mg/L ( OR = 1.88, 95% CI was 1.32-3.99, P = 0.024), infusion speed > 0.3 μg·kg -1·min -1 ( OR = 2.43, 95% CI was 2.38-2.51, P = 0.029) and diameter of needles < 20 G ( OR = 3.11, 95% CI was 3.09-3.22, P = 0.033).③ Medical personnel factors: lack of observation and assessment ( OR = 1.09, 95% CI was 1.03-6.77, P = 0.043). The ROC curve analysis showed that: edema, long-term infusion (> 24 hours), infusion rate > 0.3 μg·kg -1·min -1and diameter of needles < 20 G had a certain predictive value for extravasation of NE through peripheral venous infusion in patients with septic shock, the area under ROC curve (AUC) was 0.610, 0.762, 0.672, 0.629, 95% CI was 0.508-0.713, 0.675-0.849, 0.571-0.772, 0.525-0.732, and P values were 0.044, 0.000, 0.002, 0.019, respectively. Conclusions:Hypertension, edema, long-term infusion (> 24 hours), infusion concentration > 60 mg/L, infusion speed > 0.3 μg·kg -1·min -1, diameter of needle < 20 G, and lack of observation and evaluation by medical staff regularly were risk factors affecting the safety of peripheral intravenous NE in patients with septic shock. Peripheral NE should be avoided in the presence of the above risk factors.
