Biological ultrasonic (US),photoacoustic (PA) and magnetoacoustic (MA) imaging techniques had similar imaging principles and complementary characteristics.Combined US,PA or MA imaging can provide joint images of biological tissues which present complementary information for more comprehensive characterization of tissues in contrast to single imaging technique.The pathological tissues could be precisely located and their morphology and composition could be accurately identified.This review presented current progresses in combined PA-US,MA-US and US-PA-MA imaging techniques,espeically endoscopic imaging,focusing on the technical aspects of integration and their applications in biomedicine.

Objective To study the results using T-tube and retroperitoneal space drainage to manage perforating injury of the distal common bile duct(PIDC) during common bile duct(CBD) exploration.Methods We retrospectively analyzed the clinical data of 12 patients who were diagnosed to suffer from PIDC during CBD exploration from 2010 to 2012.Result All these 12 patients who received T-tube and retroperitoneal space drainage,gastrointestinal decompression,nutritional support and antibiotics recovered uneventfully.Conclusion Given that the CBD was unobstructed,T-tube and retroperitoneal space drainage was an good treatment for patients with PIDC.

OBJECTIVE: To investigate the relationship between syndrome differentiation of traditional Chinese medicine (TCM) and characteristic changes of vascular endothelial function in patients with diabetic arterial occlusion (DAO) of lower extremities. METHODS: Forty patients with DAO were selected as trial group. Twenty patients among them were attributed to blood stasis syndrome (group A1), and the others were attributed to syndrome of pathogenic dampness-heat attacking the lower limb (group A2) according to syndrome differentiation type of TCM. Patients with diabetes (group B), arteriosclerosis obliterans (group C) and healthy people (group D) were observed as the control groups, respectively. There were 20 cases in each group. Endothelium-dependent dilation (EDD) and endothelium-independent dilation (EID) were measured by high resolution ultrasound in the 100 subjects and the changes of vascular tension factors were also studied. RESULTS: The results showed that EDD in group A was reduced significantly as compared with that in the groups B, C and D. The levels of vascular contractile factors such as endothelin-1 (ET-1) and thromboxane B2 (TXB2) in group A were higher than those in the groups B, C and D, while the levels of vascular dilatory factors such as nitric oxide (NO) and 6-keto-prostaglandin F1alpha(6-Keto-PGF1alpha) were declined significantly as compared with those in the groups B and D. Linear correlation analysis showed that EDD was correlated positively with the levels of NO and 6-Keto-PGF1alpha, while the levels of ET-1 and TXB2 had negative correlation with EDD. EDD and EID in group A2 were declined significantly as compared with those in group A1. CONCLUSION: Our findings indicate that endothelial dysfunction may play an important role in the pathogenesis of DAO and may be associated with syndrome differentiation of TCM.

Objective To improve the diagnosis and treatment of renal inflammatory pseudotumor (RIP). Methods 10 cases of RIP treated from 1970 to 1999 were reviewed and the diagnosis and treatment were discussed. Results The main clinical manifestation of RIP were fever,lumbago and hematuria.6 of 10 underwent nephrectomy because of the suspicion of kidney cancer whereas the other 4 were cured by antibiotics without recurrence on following up for 1～5 years. Conclusions RIP is rare,the diagnosis being based on clinical symptoms together with dynamic B ultrasound and CT scan.Needle biopsy is indicated to establish the diagnosis if necessary.Antibiotics is usually effective.

Objective To Screen out incidence of vitamin K deficiecy and complicated with hemorrhage in newborn patients, infant patients and normal neonates, and also study on the treatment of vitamin K deficiency. Methods Using emzymoimmunoelectrophoresis to test PIVKA Ⅱ in umbilical and vein blood. Results The incidence of vitamin K deficiency in normal neonates, newborn patients (≤ 5 days) and infants patients (25~60 days) are 31.2%,47.6% and 31.8%. The incidence of hemorrhage in newborn patients (≤5 days) is 26.0%, infant patients (25~60 days) is 66.6%. Intramuscular injection of vitamin K 1 1 mg is the proper dosage to prevent and treat vitamin K deficiency. Conclusion The neonates right after birth or about 25 days after birth, especially those of breast feeding and who are getting lievr and gall diseases should receive vitamin K 1 to prevent vitamin K deficiency.

Objective To analyze the application rules of Jiaotong Xinshentreating principle in modern clinic based on TCM inheritance auxiliary platform.MethodsJiaotong Xinshen treating principle related prescriptions in CNKI and Wanfang databases were analyzed.“Jiaotong Xinshen”and “Xinshen Bujiao” were set as key words to retrieve relevant prescriptions in the databases. TCM inheritance auxiliary platform (V2.5) software was used to establish database. Data mining methods, such as frequency statistics and association rules were used to analyze new prescriptions aboutJiaotong Xinshen treating principle guided medication rules.ResultsTotally186 prescriptions were collected and analyzed. Medicine frequency and association rules among medicines in the prescriptions were confirmed. 12 medical combinations and 6 new prescriptions were mined.ConclusionThe data management platform and data mining methods can be applied in discovering the prescription patterns and medications rules ofJiaotong Xinshen treating principle in clinical application.

Objective To investigate the possible role of valsartan(Val) in transdifferentiation of human renal tubular epithelial cell line(HKC ). Methods HKC cells were divided into four groups: (1) serum-free (negative control); (2) MCP-1 + AAI-treated (positive control); (3) Val-treated alone; (4) Val-inhibition(treated with MCP-1 + AAI + Val). Then the expression of vimentin, ?-smooth muscle actin (?-SMA ) of HKC cells were assessed by indirect enzyme immunohistochemistry (IEI), and the percentage of ?-SMA(+ ) HKC cells was assessed by flow cytometry. Results No difference in expressions of vimentin and ?-SMA by IEI and the percentage of ?-SMA(+ ) HKC cells by cytometry were found between serum-free control HKC cells and Val treated ones. The expressions of vimentin and ?-SMA in positive controls were markedly stronger than negative controls; while these expressions in Val + MCP-1 + AAI-treated HKC cells were less strong than those in positive controls. The percentage of ?-SMA(+ ) HKC cells in the positive controls was significantly higher than that in negative controls(91. 8% vs 3. 1%, P

In addition to the common complications involving hepatic artery, hepatic vein and biliary tract, which have already been mentioned and discussed in the preceding parts of this article, there are some uncommon complications which have been reported in the medical literature as the case report or as the case- series analysis. This paper sums up these uncommon complications. Part of these uncommon complications can be treated with interventional therapy. It is very important for interventional radiologists to make a further understanding of the different etiology of these uncommon complications occurred after liver transplantation so as to get a comprehensive knowledge about the complications after liver transplantation.

The aim of the present study, performed on two different groups of volunteers, is to characterize the pharmacokinetics of lisinopril/hydrochlorothiazide combined tablet. After administration of high, medium and low doses of lisinopril/hydrochlorothiazide combined tablets, AUC and C(max) of two compounds both increase significantly with increase of dose. Neither normalized AUC/Dose nor C(max)/Dose has significant difference between every two tested dose groups. The similar results can be observed as for the parameters of t(max). Lisinopril and hydrochlorothiazide are both eliminated with linear characteristics. After repeated administration of lisinopril/hydrochlorothiazide combined tablets, AUC, C(max) and C(min) of lisinopril in the steady state increase. AUC and C(min) increase significantly. As for hydrochlorothiazide, AUC, C(max), C(min), and t(max) also increase in steady state. AUC and C(min) increase significantly. Administered with the test medication, lisinopril has an fluctuation index (FI) value of 2.29 and reaches a relative steady concentration. But hydrochlorothiazide has an FI value of 4.09 with relatively large fluctuating concentrations.
