Objectvive To evaluate the blood supply of pulmonary metastases using small volume of lipiodol through pulmonary arterial infusion. Methods 10 cases of lung metastasis were enroled including the primary tumors of liver cancer(n = 5), renal carcinoma(n = 3), chordoma(n = 1) and malignant neurofibroma (n = 1). Plain CT scan was performed to exclude calcification or ossification within metastasis and then pulmonary arterial DSA was undertaken to evaluate tumor vessels or staining. After pulmonary arteriovenous fistula or other anomalous circulation was excluded by lobar arterial DSA, small volume of lipiodol was infused under fluoroscopy (0.5 -1.5 ml for each lobar artery, total volume less than 3.0 ml). CT scan was immediately performed. Blood supply of the pulmonary metastases was assessed according to the accumulation of lipiodol on CT scans. Results No cases but one experienced cough, expectoration, suffocating or dyspnea. No complication of cerebral or visceral embolism occurred. Totally 27 nodules were studied including 6 nodules with cloudy lipiodol accumulation and 6 nodules with tiny granules of lipiodol accumulation. No enlarged tumor vessel or tumor stain was observed within all 27 nodules on pulmonary arterial DSA. Conclusions Pulmonary artery supplys only parts of pulmonary metastases, especially those sited at the peripheral region of the lung. Infusion of small volume of lipiodol through pulmonary artery is safe, and the increased density of lung field could return normal after several days.

Aim To evaluate the effects of pantoprazole on various experimental acute ulcer inrats and mice. Methods The model of a gastric ulcer of rats or mice was caused bystree- induced ulcer and ligatel pylurus-induced ulcer. Results & Conclusions At adose of 5, 10, 20 mg? kg-1 of Pantoprazole can markedly decrease the ulcer index ofstree-induced ulcer. Pantoprazole(4, 8, 16 mg? kg -1 ) significantly decrease the areaof ligated pylorus-induced gastric ulcer. It was also found that pantoprazole caninhibit the output of basic gastric acid.

OBJECTIVETo discuss the mechanism of scar hypertrophy in adenosine receptor A(2A) (A(2A) R) knockout mice.

METHODSAnimal models of hypertrophic scar were established in 12 A(2A) R knockout mice and 12 wild-type mice as control. The thickness and the size of transverse section of the hypertrophic scar were observed by H-E staining. The hydroxyproline (HYP) in the scar was measured colorimetrically. The TGF-beta expression was tested by Western blotting method.

RESULTSThe hypertrophic scar in wild-type mice was more severe than that in knockout mice. Compared with self-control, the increase of the thickness and the size of transverse section of hypertrophic scar was markedly higher in wild-type group than in the knockout group (P < 0.01). There was significant difference in HYP content between the two groups (P < 0.01). Compared with self-control, the increase of TGF-beta expression in wild-type group was much more than that in knockout group (P < 0.01).

CONCLUSIONSThe TGF-beta expression decreases in the A(2A) R knockout mice. The scar hypertrophy is also much less in the A(2A) R knockout mice.

OBJECTIVETo study the therapeutic mechanism of Zhizhu Pill (ZP) for treating functional dyspepsia (FD) rats.

METHODSTotally 30 ten-day-old male rats were randomly divided into the normal control group (n =10) and the model group (n = 20). The FD rat model was induced using gastric administration of 0.1% iodoacetamide (IA) combined tail clamping. The model was evaluated when rats were 8-week old. Successfully modeled rats were randomly divided into the model group (n = 10) and the ZP group (n = 10). Rats in the normal group and the model group were administered with normal saline by gastrogavage, while those in the ZP group were administered with ZP Decoction (2 mL/100 g) by gastrogavage. All medication lasted for 7 successive days. The contractile activity in in vitro longitudinal gastric muscle was recorded using Power Lab biological signal collecting system. The expression of growth hormone secretagogue receptor (GHSR) in stomach of FD rats was detected using Western blot and immunohistochemistry (IHC).

RESULTSCompared with the normal group, average frequencies of gastric contraction and changing rates of amplitude obviously decreased in the model group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR decreased in the model group (P < 0.01). Compared with the model group, average frequencies of gastric contraction and changing rates of amplitude obviously increased in the ZP group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR increased in the ZP group (P < 0.01).

CONCLUSIONZP could promote the gastric motility in FD rats induced by gastric administration of IA combined tail clamping, and its mechanism might be related to up-regulating GHSR protein level.

Objective To investigate the application value of breast scale membrane marking method to locate breast tumor lesion in neoadjuvant chemotherapy.Methods Before neoadjuvant chemotherapy for 120 cases of breast cancer,adopt scale membrane marking method was used to mark the position and boundaries of breast tumor lesion in the mean time.For non-protuberant breast tumor lesion,scale membrane was adhered directly to the breast and positive mark was made.For tumor lesion with vague boundaries,its boundaries was defined under the direction of ultrasound.For protuberant breast tumor lesion,scale membrane was only adhered to normal mammary skin beyond the tumor lesion and reverse mark was made.After two courses of treatment of TEC scheme,mark was made again and combined with ultrasound,molybdenum target and MRI results to comprehensive judgment of clinical curative efficacy so as to decide whether operation or change to TP scheme for continuous chemotherapy.Before operation,the first marking results were reset and then operation was conducted according to the position and boundaries of the marked tumor lesion.Results There were 26 cases of complete remission,76 cases of partial remission,10 cases of stabile disease and 8 cases of progressive desease.According to mark by scale membrane,breast conserving operations were conducted in 24 cases of complete remission and in 18 cases of partial remission according to position+ boundaries of the tumor lesion and tumor lesion position+ 1.5-2.0 cm beyond the original boundaries of tumor lesion marked by scale membrane,respectively.The simplified radical mastectomy was conducted in other 78 cases according to boundaries of the tumor lesion marked by scale membrane,in which 13 cases had insufficient locally advanced skin edges and adopted abdominal full-thickness free skin flap to cover the wound.Conclusion Tumor lesion location in neoadjuvant chemotherapy for breast cancer and scale membrane positioning method have the advantage of precision and non-invasion,which effectively save normal breat tissues and skin around tumor lesion with high patient compliance and tremendously outmatches traditional coordinate method,body surface tattoo method and mental marker method.Scale membrane marking method is easy to be operated with low cost,which is convenient for popularization and generalization.

OBJECTIVE: To observe ultrastructure changes of electrical injury in rats. METHODS: An experimental model of rats suffered from the low voltage were designed. Ultrastructure changes of electrical injured tissues were observed under transmission electron microscope. RESULTS: (1) Plasma of epithelium was concreted in the affected areas and inner membrane system was broken. (2) Hypercontraction bands were observed in skeleton muscles. (3) There was dissolved necrosis and hypercontraction bands in the myocardium. (4) Vacuoles were found in plasma of endothelium of blood vessels on electrical current path, and myelin sheath of nerve fiber were loosed. CONCLUSION The above mentioned ultrastructure changes could be used as assistant diagnostic index of electrocution. The mechanism of the changes were discussed.
