Objective: To observe the promoting blood circulation by removing blood stasis of Lubai Capsule(LBC)(Rhizoma Phragmitis, Radix Paeoniae Alba, Radix Saposhnikoviae, Flos Schizonepetae, etc.). Methods: Acute blood stasis rat models were established with swimming in iced water and sc adrenalin in order to observe the effect of LBC on blood rheology. Mesenteric microcirculatory disturbance rat models were also established with adrenalin in order to observe the effect of LBC. Clotting time was measured in vitro with prothrombin time(PT) and kaolin partial thromboplastin time(KPTT) kit in order to observe its effects. Results: LBC could decrease the whole blood and plasma viscosity, fibrinogen, erythrocyte sedimentation and aggregation ratio of blood platelets of rats, ease the sticky condition of blood stasis rat models and prevent from forming thrombus. It could also inhibit the constraction and slowing of blood flow of thin artery, the reducing of open capillaries and change of fluid condition caused by adrenalin and improve these phenomena. PT and KPTT could be increased obviously. Conclusion: LBC can significantly promote blood circulation by removing blood stasis, because of improving blood rheology and mesenteric microcirculatory disturbance and inhibit endogenous and exogenous coagulation system.

Objective:To investigate the efficiency and safety of peritoneal dialysis (PD) in pediatric patients with acute kidney injury (AKI).Method:A retrospective study of children who underwent PD for AKI in the First Affiliated Hospital of Xi’an Jiaotong University from 2003 to 2013 was performed, and the laboratory examinations, the causes, the complication, the prognosis and the risk factors were evaluated.Results:The study included 48 children, with the age of (67.6±51.7) months (ranging from 3 months to 15 years old), including 31 males (64.6%) and 34 co-infections (70.8%). Primary glomerulonephritis (27.1%) was the most common cause of AKI, followed by the hemolytic uremic syndrome (18.7%) and drug induced AKI (18.7%). Peritoneal dialysis was performed manually using percutaneous or adapted catheters. The duration of PD during hospitalization was 11(7,14) days. PD treatment was highly effective in attenuation of toxics retention and correction of electrolyte disturbances (all P<0.05). There were 3 cases of PD-related complications, including 1 case of peritonitis, 1 case of catheter outflow obstruction, 1 case of catheter exit site hematoma, and no child patient died of PD complications. Among the AKI children, 37 cases (77.1%) recovered with the PD treatment and had the catheter successfully removed till discharge, 7 cases (14.6%) needed further peritoneal dialysis and 4 cases (8.3%) died. The serum albumin level was significantly higher in patients who got recovered with PD treatment than other unrecovered cases [(32.6±6.7) g/L vs (23.2±4.3) g/L, t=-3.994, P<0.001]. Conclusions:PD can be safely and efficiently performed for the treatment of pediatric AKI. Low albumin level may be related to poor prognosis of AKI.

Objective To investigate the correlation between lung ultrasonography and pulmonary complications after cardiac surgery. Methods Fifty-two patients after cardiac surgery in our hospital from January to May 2017 were recruited. There were 27 males and 25 females, aged 60.50±10.43 years. Lung ultrasonography was performed by specially trained observers, video data were saved, and lung ultrasound score (LUS) were recorded. The correlation between the LUS and the patients' pulmonary function was evaluated. Results LUS was 17.80±3.87, which was negatively correlated to the ratio of arterial PO2 to the inspired oxygen fraction (PaO2/FiO2) during examination, without significant difference (r=–0.363, P=0.095), but significantly negatively correlated to PaO2/FiO2 changes 24 hours postoperatively (r=–0.464, P=0.034). Conclusion The changes of lung ventilation area may occur earlier than the changes of lung function. Bedside LUS is an effective method for clinical monitoring of pulmonary complications.

Objective :
The purpose of this study was to investigate the relevant social and environmental factors affecting the occurrence of periodontal diseases during pregnancy in pregnant women and to analyze the influence of the periodontal status of women in the second trimester of pregnancy on small for gestational age (SGA) delivery.
Methods:
A total of 215 pregnant women were enrolled in this study in the Department of Periodontology of the West China Hospital of Stomatology of Sichuan University from May 2015 to May 2018. Periodontal parameters, such as bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL), were recorded at 16-24 weeks of gestational age. Subjects were divided into the periodontitis (n=32) group, gingivitis (n=171) group and periodontally healthy (n=12) group according to their periodontal conditions. With the patient′s informed consent, the patient decided whether to receive periodontal treatment. Basic and socioeconomic information was collected through questionnaires. After delivery, subjects were divided into the SGA group and non-SGA group according to their birth results. The periodontal clinical indicators, questionnaire results and delivery results were compared among the groups.
Results :
The mean PD (P=0.005, r=-0.192) and BOP% (P=0.003, r=-0.199) were negatively correlated with economic income. The family income in the periodontitis group was significantly lower than that in the healthy group and the gingivitis group (P < 0.05). The flossing use rate was significantly higher in the healthy group than that in the gingivitis group (P < 0.05). A total of 106 pregnant women received scaling and root planing, while 109 patients only received oral hygiene instruction. After delivery, SGA occurred in 23 cases (10.7%), and there were no significant difference in SGA incidence among the three groups (P > 0.05). PD ≥ 5 mm% and PD ≥ 4 mm% (P < 0.05) were significantly higher in the SGA group than in the non-SGA group. There was no significant difference in SGA incidence between the treated group and the untreated group (P > 0.05).
Conclusion
Family income and dental flossing use have an impact on the incidence of periodontal diseases during pregnancy. The severity of periodontitis in pregnant women is correlated with the incidence of SGA.
