Objective:To analyze the relationship between plasma uranium concentration and renal injury.Methods:A case-control study was conducted in Hunan province, involving 102 renal injury cases and 102 matched controls. The association between plasma uranium concentration and renal injury was analyzed using conditional logistic regression models, and the dose-response relationship was analyzed through restricted cubic spline regression. The linear regression model and Spearman correlation were used to analyze the association between plasma uranium concentration and renal injury indicators.Results:The median of plasma uranium concentration was 8.94 ng/L in all subjects and 10.19 ng/L in the case group. The plasma uranium may be a risk factor for renal injury, with a dose-response relationship between the both representing nonlinear association ( χ2=5.15, P<0.05). The risk of renal injury was 4.21 times higher in the group exposed to highest uranium concentration than that in the group exposed to lowest uranium concentration. Plasma uranium concentration was closely related to glomerular filtration rate, serum creatinine and β 2-microglobulin ( r=0.211, -0.142, 0.195, P<0.05). Conclusions:The plasma uranium concentration is significantly associated with the renal injury, which may provide epidemiology evidence for the prevention of renal injury.

Background Exposure to uranium can result in multi-organ toxicity in humans. Some experimental studies have shown that uranium presents a damaging effect on liver, but no relevant population studies have been reported. Objective To investigate a potential association of plasma uranium exposure with liver injury. Methods The inhabitants of two representative areas of heavy metal pollution in northern and southern Hunan were selected as the research subjects. A total of 740 participants were recruited through 1∶1 paired case-control design based on a pre-determined diagnostic criterion for liver injury (defined as two or more anomalies among alanine aminotransferase, aspartate aminotransferase, and total bilirubin in the health examination) and the principle of case-control comparability. Information such as general demographic characteristics and medical history were collected through questionnaires and physical examination. Plasma uranium and liver function were determined by laboratory tests. Spearman correlation was applied to assess the association between plasma uranium concentration and liver injury indexes, and restricted cubic spline model was used to evaluate the dose-response relationship between plasma uranium concentration and liver injury. The participants were divided into four groups from Q1 to Q4 according to the quartile values of plasma uranium concentration of the control group after natural logarithmic transformation (with the Q1 group as the reference group), and the association between plasma uranium concentration and liver injury was evaluated by conditional logistic regression. Results The plasma uranium level in M (P₂₅, P₇₅) of the case group was 10.89 (6.78-18.53) ng·L⁻¹, higher than that in the control group, 9.26 (5.01-14.38) ng·L⁻¹ (P<0.001). The results of Spearman correlation analysis showed that alanine aminotransferase and aspartate aminotransferase were positively correlated with plasma uranium level (r_s=0.138, r_s=0.167; P<0.001). The restricted cubic spline model showed that the risk of liver injury increased with the increase of plasma uranium concentration (overall effect P<0.001). After adjusting for confounding factors such as gender, age, smoking, alcohol consumption, and prevalence of hypertension and hyperlipidemia, the results of conditional logistic regression analysis showed that the risks of liver injury in the Q2 group, the Q3 group, and the Q4 group were 2.043 (95%CI: 1.135-3.680), 2.246 (95%CI: 1.238-4.075), and 3.536 (95%CI: 1.955-6.397) times higher than that of the Q1 group respectively. Conclusion Plasma uranium exposure is associated with liver injury. This study is the first to provide population-level evidence of such an association.

Objective The study was aimed to explore the effect of care bundles on the management of nasal intestine for the cerebral apoplexy patients with dyspinic dysfunction. Methods A total of 102 cerebral apoplexy patients with dyspinic dysfunction, who were administrated with nasal intestine, were recruited in Qianfoshan Hospital of Shandong Province from August, 2016 to June, 2017. Random number table was applied to analyze the separate two groups, experimental group and control group, in which, the patients were administrated with care bundles and usual care. Various parameters, like one-time catheterization, complications of nasal intestine administration, hospital stay, cost and the patients' satisfaction degree, were compared between two groups. Results The success rate of once placed tube in the test group was 78.4％ (40/51), which was significantly higher than that in the control group [54.9％(28/51)], and the difference was statistically significant (χ2=6.353, P<0.05). The incidence of complications of indwelling nasoenteric tube, including unplanned extubation, reflux aspiration, tube-feeding associated diarrhea, were 9.8％(5/51), 17.6％(9/51), 11.8％(6/51), respectively. All of them were significantly lower than those of the control group, which were 37.3％(19/51), 41.2％(21/51), 31.4％(16/51), respectively, indicating that there was a statistical difference (χ2= 10.679, 6.800, 5.795). The days and costs of hospitalization were (11.0 ± 2.5) d, (9645.35 ± 193.30) yuan, respectively, which were significantly lower than those of the control group [(17.0 ± 4.2) d, (12523.79 ± 190.28) yuan], indicating that there was a statistical difference (t=8.767, 10.612, P<0.01). Patients' satisfaction was 90.2％(46/51), which was significantly higher than that of the control group [68.6％ (35/51)]. The difference was statistically significant (χ2=7.256, P<0.01). Conclusions The administration of care bundles for the cerebral apoplexy patients with dyspinic dysfunction can effectively increase the success rate of one-time catheterization, alleviate the complications, and therefore reduce the risk of aspiration pneumonia development. In addition, care bundles can remarkably alleviate the medical burden on the patients, shorten the hospital stays and improve the survival quality of the patients.

Objective To discuss the clinical application of percutaneous transhepatic removal of gall-stone technique in treating common bile duct (CBD) stones.Methods Between January 2013 and January 2015,a total of 25 patients with CBD stones underwent lithotomy procedure via percutaneous transhepatic route.First,under ultrasound or fluoroscopy guidance percutaneous transhepatic cholangiography (PTC) was performed with subsequent placement of an 8 F rsheath;then,a balloon of 8-12 mm diameter was employed to dilate the papilla;mechanical lithotripsy was adopted when the stone size exceeded 12 mm;finally,through guide-wire exchange technique the stone-retrieval balloon was used to push the stones into the intestinal tract through the sphincter of duodenal papilla.Results The reasons to receive percutaneous transhepatic removal of gall-stone technique in the 25 patients included previous gastrointestinal surgery (n=18),endoscopic treatment failure (n=3),unwilling to receive endoscopic treatment (n=3),and other reasons (n=1).Successful removal of stones was accomplished in all 25 patients.After the treatment,complications occurred in 3 patients (12％),including fever (n=2) and liver abscess formation (n=1).The patients were followed up for 0.5-3 years;two patients died of tumor recurrence and metastasis,and one patient developed recurrence of common bile duct stones.No reflux cholangitis occurred.Conclusion For the treatment of CBD stones,percutaneous transhepatic removal of gall-stone technique carries higher technical success rate with lower incidence of complications,therefore,this technique can be used for the patients who are not suitable for endoscopic treatment or in whom endoscopic treatment failed.
