Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.
4.Early changes of plasma angiopoietin-2 in patients with multiple trauma
World Journal of Emergency Medicine 2011;2(4):287-290
BACKGROUND: This study was undertaken to investigate the early changes of plasma levels of angiopoietin-2 (Ang-2) in patients with multiple trauma and the relations of plasma Ang-2, endothelial injury, and prognosis. METHODS: This study comprised 59 patients with multiple trauma who had been treated at the emergency department of Liao Cheng People′s Hospital from January 2008 to January 2010. Among them, 36 were male and 23 female. Their average age was 32.3±11.5 years. The 59 patients were divided into a severe trauma group (ISS≥16 points, 29 patients) and a slight trauma group (ISS<16 points, 30 patients) by injury severity score (ISS). Thirty healthy people aged more than 18 years with an average of 33.5±10.6 years served as controls (19 male and 11 female). Peripheral blood (10 mL) was collected within 10 minutes after the patients arrived at the emergency department, and plasma was separated from the blood. Enzyme-linked immunosorbent assay (ELISA) was applied to detect the levels of angiopoietin 2, thrombomodulin (TM), and Von willebrand factor (vWF). RESULTS: The level of Ang-2 in the severe trauma group (ISS score≥16 points) was significantly higher than that in the slight trauma group (ISS score<16 points) (P<0.05). The levels in the two groups were significantly higher than those in the control group (P<0.05). The levels of angiopoietin-2 in deaths were significantly higher than those in survivors (P<0.05). The levels of angiopoietin-2 were significantly correlated with the levels of vWF and TM (P<0.05). CONCLUSIONS: The plasma levels of Ang-2 are significantly higher after multiple trauma, and correlated with the degree of trauma severity. The levels of angiopoietin-2 are correlated with endothelial injury after multiple trauma, and are important values for the prognosis of patients with multiple trauma.

Hide melting presents itself as one of the most critical processes in the production of donkey-hide gelatin. Here a NIR-based method was established for the rapid analysis of in-process hide melting solutions as well as for end-point determination of this process. Near infrared (NIR) spectra of hide melting solutions were collected in transflective mode. With the contents of total nitrogen determined by the Kjeldahl method as reference values, partial least squares regression (PLSR) was employed to build calibration models between NIR spectra and total nitrogen. Model parameters including wavelength range and PLS factors were optimized to achieve best model performance. Based on the contents of total nitrogen predicted by calibration model, end point of hide melting was determined. The constructed PLS model gave a high correlation coefficient (R2) of 0.991 3 and a root mean square error of prediction (RMSEP) of 0.807 g x L(-1). With the predicted total nitrogen and predefined limit, decisions concerning the proper times of melting were made. This research demonstrated that NIR transflectance spectroscopy could be used to expeditiously determine the contents of total nitrogen which was subsequently chosen as the indictor for determining the end-point of hide melting. The proposed procedure may help avoid unnecessary raw material or energy consumption.

Xiatianwu tablet is based on the theory of traditional Chinese medicine (TCM), combined with modern TCM pharmacology and selected 33 famous traditional Chinese crude drugs to compose. Its recipe helps cure rheumatism, relax tendons, promote blood circulation to relieve pain, et al. Although Xiatianwu tablets are widely applied to clinical remedy such as rheumatic arthritis, lumbar disc hernia, osteoarthritis and so on, there is no report about its application in fracture. This article is to observe the efficacy of compound Xiatianwu tablets in elderly patients with osteoporotic distal radius fractures and its impact on the wrist function and complications. 180 elderly patients with osteoporotic distal radius fractures, from January 2011 to June 2014, were divided into observation group and control group by the method of random number table, each group had 90 cases. The control group were gave Caltrate D after manipulative reduction and plaster immobilization, observation group were treated with compound Xiatianwu tablets in the basis of the control group. Efficacy, wrist function and complication rates were observed in two groups after treatment. The excellent and good rate was 95.56% in observation group better than 77.78% in control group, the difference was statistically significant (χ2 = 4.712, P < 0.05). The complication rate in observation group was significantly lower compared with the control group (P < 0.05). This study shows that compound Xiatianwu tablets can improve the efficacy in elderly patients with osteoporotic distal radius fractures, reduce the incidence of complications and relieve the pain of patients which plays a significant role in improving the quality of life.

?AIM: To explore the relation of homocysteine ( Hcy ) and its metabolic related indicators with primary angle-closure glaucoma ( PACG) .?METHODS: In this study, a total of 150 PACG patients and 150 controls were enrolled. The patients with PACG were diagnosed by applanation tonometer, Humphrey perimetry ( HVF ) , optical coherence tomography ( OCT ) , gonioscope. The normal controls were recruited from physical examination center. Blood samples were collected and the plasma was used to determine homocysteine, vitamin B12 and folic acid. DNA was extracted to determine the methylenetetrahydrofolate reductase ( MTHFR ) C677TT genotype and gene polymorphism.?RESULTS:There was a statistically significant difference (t=2. 04,P=0. 04) in mean homocysteine levels between patients with PACG ( 16. 11 ± 1. 66μmol/L ) and controls (15. 74± 1. 52μmol/L). The level of vitamin B12 in PACG group was 248. 09 ± 119. 07pg/mL and the control group was 230. 21 ± 142. 93pg/mL. No statistically significant difference was found on the vitamin B12 level between the two groups ( t = 0. 84, P = 0. 40 ). The folic acid levels showed no statistically significant differences( t=1. 65,P=0.17) between the PACG group(12. 02±7. 81ng/mL) and the control group (13. 15 ± 6. 25ng/mL). The frequency distribution of the MTHFR C677T genotypes was found to be significantly associated (χ2 =6. 2,P<0. 05) with PCAG (CC 84. 7%, CT 4. 7%, TT 10. 7%) as compared to the controls (CC 94. 7%, CT 2. 0%, TT 3. 3%). The frequency distribution of TT genotypes of MTHFR C677T in the PACG group was significantly higher than that in the control group. Moreover, our findings showed significant difference (χ2=14. 2,P<0. 05) between the allele frequency of the C677T single nucleotide polymorphism within the MTHFR gene in POAG patients ( T 87. 0%, C 13. 0%) and the control group(T 95. 7%,C 4. 3%) .?CONCLUSION: These results show that the Hcy level and the TT genotypes of MTHFR C677T were higher in the PACG patients than in controls. Therefore, our data suggests that high Hcy level and the related indicators are associated with high PACG risk.
