Purpose Bronchial arterial embolization is the preferred hemostasis method for hemoptysis when medical treatment is invalid. This paper aims to discuss the safety and efficacy of inferior phrenic artery (IPA) embolization in the treatment of hemoptysis of tuberculosis when IPA is involved. Materials and Methods Twenty-eight patients who were confirmed that IPA got involved in the hemoptysis due to pulmonary tuberculosis by IPA angiography underwent embolization. CT scan was performed before the procedure and IPAs arteriography were performed during the interventional procedure. Once the blood supply was identified, catheterization and embolization was carried out with gelatin sponge particle, sodium polymannuronate microsphere or microcoil according to the patients' conditions. After the procedure, the IPA angiographic manifestations, clinical efficacy and complications were evaluated. Results Thirty-three IPAs were identified as getting involved in the blood supply in the 28 patients. Among those patients, 12 had left IPA involved, 11 had right IPA involved and the rest 5 had IPAs involved in both sides. The selective IPA angiography showed IPAs had enlargement, with numberous and disordered branches and hypervascularity. IPA-pulmonary artery shunt was found in 22 cases. None of the cases was found extravasation of contrast medium. The hemoptysis reoccurred in 4 patients on the second day, sixth day and 6 months after the first embolization, thus the procedures were performed three times in 1 patient and twice in the other 3 patients. Nine patients had fever as complication, 19 patients had chest pain and 5 suffered from mild dyspnea. These complications usually disappeared in 3-7 days after symptomatic treatment. Conclusion IPA embolization is technically feasible and safe, whose complications are likely to be few and self-restrictive.

Objective To observe the effects of Triptolide on the expression of toll-like receptor 4 (TLR4) in renal ischemia/reperfusion (I/R) injury in rats. Methods A renal I/R model was established. Rats were randomly separated into the following experimental groups. Group 1, shamoperated control (n = 15) : rats were subjected to surgical manipulation, without the induction of renal ischemia. Group 2, I/R (n = 18): rats were subjected to left renal ischemia for 45 min followed by reperfusion. Group 3, TRI + I/R (n = 18): Before the I/R procedure (as in group 2), rats were intraperitoneally injected with TRI (0.4 mg/kg), once every day, three times. Rats were killed at the 1st, 3rd, and 5th day after I/R injury. The parameters of renal function were determined by autobiochemical analyzer. The expression of TLR4 was detected by RT-PCR and Western blotting. Results As comparedwith the sham-operated control group, serum BUN and Cr levels were significantly increased in the rats undergoing I/R procedure at the 1st, 3rd, and 5th day (P<0. 01). After the treatment with TRI, the levels of BUN and Cr and the expression of TLR4 in the renal tissues were significantly decreased (P<0. 05). Conclusion TRI could relieve renal I/R injury in rats by inhibiting the TLR4 expression.

Objective To evaluate the predictive value of urinary neutrophil gelatinase-associat-ed lipocalin (NGAL) and interleukin-18 (IL-18) for delayed graft function (DGF) in kidney transplan-tation. Methods Serial urine samples collected at 0, 12 and 24 h after operation from 86 kidney transplantation patients were analyzed by enzyme-linked immunosorbent assay for NGAL, IL-18 and RBP. Results Fifteen patients developed DGF. At 12 h after transplantation, the level of urine NGAL elevated significantly (1712.75±474.6 vs. 863.1±199.8 without DGF, P<0. 001). The in-creases of urine IL-18 (29. 2±4.1 vs. 28.7±4.2 without DGF, P>0. 05) was not significant. At 24 h, both urine NGAL(2905.0±1108.1 vs. 911.8±221.0 without DGF,P<0. 001) and IL-18(211.3± 34.0 vs. 86.9±22.8 without DGF, P<0. 001) increased significantly, whereas the changes of urine RBP and serum creatinine (SCr) were not significant. ROC analysis showed that the area under the curve of NGAL and IL-18 were 0. 90 and 0.76 respectively, the cut-off values were 996.5 ng/mg and 148.5 ng/mg, the diagnostic sensitivities in DGF were 90.2% and 76.3%, specificities were 82.6% and 66.4% respectively. Conclusions Both urine NGAL and IL-18 could potentially be early predic-tive marker of DGF. The level of NGAL elevated earlier than IL-18, which may be more effective in predicting DGF.

Objective To discuss the value of digital tomosynthesis for detection of pulmonary nodules. Methods Thirty patients suspected of having pulmonary nodules underwent chest radiography, digital tomosynthesis and CT examination. Above image data were transferred to postprocessing work station and were reviewed by 2 radiologists with 3 years of chest-radiology diagnosis experience in a double-blind method. The number, location and size of nodules were recorded. Then, 2 radiologists reviewed the all images once more, and discuss in consensus. The sensitivities of chest radiography and digital tomosynthesis for detection of pulmonary nodules were respectively calculated according to the CT results. Chi-square test was used for radiography, digital tomosynthesis and CT examination. Results Of 30 patients, 21 were detected having pulmonary nodules by X-ray radiography and 9 were negative, the total number of 40 nodules was detected, while 89 nodules in 26 patients were detected by digital tomosynthesis, and only 4 patients were negative. CT demonstrated 102 nodules in 27 patients, and 3 patients were negative. Taking CT as "gold standard", the sensitivities of X-ray radiography and digital tomosynthesis were 27.4%(28/102)and 87.2%(89/102), X~2=4.35, P<0.05, respectively. Conclusion Digital tomosynthesis has a high sensitivity for detection of pulmonary nodules compared with X-ray radiography, and could be an excellent and necessary supplementary technique of X-ray radiography.
