The aim of this study was to investigate the immunological function regulated by Fufang Hongjingtian capsule (HJT) in mice. The mice were given ig HJT 25, 250 and 750 mg/kg, once daily, for 30 - 38 d, respectively. The mice in control group were given ig corresponding solvent. After the last time of administration, the immunological parameters of the mice were measured. The results showed that compared with negative control group, the delayed type hypersensitivity, spleen lymphocyte proliferation and number of spleen IgM antibody forming cells increased in HJT groups. In conclusion the HJT has the effect to improve the immunological functions of mice.

OBJECTIVETo investigate the possibility and the limit in increasing the survival area of the random skin flap by extremely increasing the ratio of its length and width within 24 hours.

METHODSSD rats (n = 20) were chosen for this study. The rats were randomly divided into: subject group and control one. Pre-made skin flap was prepared as design. The subject group was carried out rapid pre-fabricated skin flap formation training. No training was performed in control group. The changes in perfusion value of micro-circulation inside skin flap were monitored during the whole process, and micro-circulation parameters of the skin flap were used to evaluate whether its blood circulation network was mature or not.

RESULTSTraining of pre-made skin flap at 18th hour, the perfusion value of its micro-circulation was basically stable, Skin flap formation was finished at 24th hour. Survival area in control group was (68.25 +/- 0.18)% and in subject group was (97.25 +/- 0.24)% (P < 0.01). There was a significant difference between the two groups.

CONCLUSIONSWithin short time, it is possible to establish micro-circulation in skin flap which exceeds the limit set by traditional theory. Digitalized judgment can be used to monitor the fast formation of super-big skin flap. This method is reliable and can increase the survival rate of random skin flap.

OBJECTIVETo observe the effect of Compound Shenhua Tablet (, SHT) on the sodium-potassium- exchanging adenosinetriphosphatase (Na(+)-K(+)-ATPase) in the renal tubular epithelial cells of rats with acute ischemic reperfusion and to investigate the mechanisms underlying the effects of SHT on renal ischemic reperfusion injury (RIRI).

METHODSFifty male Wistar rats were randomly divided into the sham surgery group, model group, astragaloside group [150 mg/(kg·d)], SHT low-dose group [1.5 g/(kg·d)] and SHT high-dose group [3.0 g/(kg·d)], with 10 rats in each group. After 1 week of continuous intragastric drug administration, surgery was performed to establish the model. At either 24 or 72 h after the surgery, 5 rats in each group were sacrificed, blood biochemistry, renal pathology, immunoblot and immunohistochemical examinations were performed, and double immunofluorescence staining was observed under a laser confocal microscope.

RESULTSCompared with the sham surgery group, the serum creatinine (SCr) and blood urea nitrogen (BUN) levels were significantly increased, Na(+)-K(+)-ATPase protein level was decreased, and kidney injury molecule-1 (KIM-1) protein level was increased in the model group after the surgery (P<0.01 or P<0.05). Compared with the model group, the SCr, BUN, pathological scores, Na(+)-K(+)-ATPase, and the KIM-1 protein level of the three treatment groups were significantly improved at 72 h after the surgery (P<0.05 or P<0.01). And the SCr, BUN of the SHT low- and high-dose groups, and the pathological scores of the SHT high-dose group were significantly lower than those of the astragaloside group (P<0.05). The localizations of Na(+)-K(+)-ATPase and megalin of the model group were disrupted, with the distribution areas overlapping with each other and alternately arranged. The severity of the disruption was slightly milder in three treatment groups compared with that of the model group. The results of immunofluorescence staining showed that the SHT high-dose group had a superior effect as compared with the astragaloside group and the SHT low-dose group.

CONCLUSIONSThe SHT effectively alleviated RIRI caused by ischemic reperfusion, promoted the recovery of the polarity of renal tubular epithelial cells, and protected the renal tubules. The therapeutic effects of SHT were superior to those of astragaloside as a single agent.

A 68-year-old female patient was treated for unhealed ulcer in the fourth toe of the left foot. Clinical examinations identified severe stenosis of the proximal segment and occlusion of the distal segment of the left anterior tibial artery, and occlusion of the left posterior tibial artery and the peroneal artery. The proximal stenotic segment of the left anterior tibial artery was dilated, but the distal occlusive part failed to be re-canalized. Left anterior tibial artery to dorsal pedal artery bypass was performed on the patient with an epoxide-crosslinked, special radicals antigen-sealed, porcine-derived biological graft; debridement of the left 4th digiti pedis was also performed. Postoperation course was uneventful. The pulse of the left dorsal pedal artery was strong. The ankle brachial index (ABI) increased from 0.60 to 1.09. Warfarin and two antiplatelet drugs were given after the operation. Six months after operation, computed tomographic angiogram (CTA) identified the patent graft.
