Objective To evaluate the outcome of super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy (PCNL) and its effect on renal function. Methods From May 2008 to Feb 2010,severe bleeding occurred in 7 patients after PCNL in our hospital.(5 males and 2 females,average age of 54.9 years ).All cases were treated with super-selective renal angiography and 6 cases underwent microcoil embolization. Results Renal angiography showed pseudoaneurysm in 5 cases,pseudoaneurysm with arteriovenous fistula in 1 case and no severe bleeding in 1 case.Successful coil embolization was confirmed in 6 cases by angiography,and bleeding stopped within 3 -7 days after embolization.Serum creatinine and blood urea nitrogen were 59 -98 μmol/L(mean,78.3 μmol/L) and 1.86 -6.92 mmol/L( mean,4.8 mmol/L) 2 weeks after embolization,respectively. Conclusions Super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy has the advantages of remarkable hemostatic effects and mild impaired renal function,which is of the first choice.

A fragment sized 400bp of White spot syndrome virus(WS SV,formerly de signated NOSV),recovered from recombinant plasmid pAFD, was labeled with Digox igenin as a probe to detect dynamic distribution of WSSV within 120h and 72h in crawfishes(Cambarus proclarkii) inoculated WSSV by oral taking and injecti on r espectively. Stomach epithelium, intestine epithelium, heart, gill, haemolymph, muscle, hepatopancreas, hypoderm, connective tissue and ovary of infected crawfi shes were examined for WSSV. In both groups, WSSV was first detected in heamoly mph at 12h p.i. and then disappeared. Again it was detected at 96h p.i. only in oral infection group and maintained till 120h p.i., but it didn't appear at 72h p.i. in injection group. WSSV in heart, muscle was detected at 36h p.i. in oral infection group and 24h p.i. in injection group respectively, and then increased generally. In addition, WSSV in intestine epithelium, connective tissue, ovary of oral infection group and intestine epithelium, hypoderm, ovary of injection g roup could also be detected. In dead crawfishes after 120h and 72h p.i. in two groups, WSSV could be detected in all the examined tissues and it demonstrated t hat systemic infection occurred in the animales. The tissue containing more amo unts of WSSV was hypoderm in oral infection group, while intestine epithelium, g ill, hypoderm, ovary in injection infection group. It deduced that WSSV first a ppears in haemolymph and then goes into heart, muscle and other tissues and prol iferates in them. Once again, WSSV is released into heamolymph resulting in syst emic infection till crawfishes' death.

Objective To investigate whether erythropoietin(Epo) is potentially beneficial in protecting cultured retinal neurocytes.Methods Primary isolated retinal nerve cells were cultured.Expressions of Epo and EpoR protein in cultured retinal neurocytes were decected by immunohistochemical analysis.Survival of cultured neurocytes that were incubated in the presence of Epo or glutamate in the presence or absence of Epo were estimated by determining the activity of their mitochondrial dehydrogenases using the MTT assay.Results Epo and EpoR protein were expressed on the cultured retinal neurocytes.The presence of different concentrations of Epo did not improve the survival of retinal neurocytes,and Epo could prevent glutamateinduced toxicity. Conclusion Epo is beneficial in protecting mixed cultured retinal neurocytes from glutamate-induced cytotoxicity.

Acetylcholine and A23187, two acetylcholinergic agonists, were used to induce the stimulus-secretion coupling of the isolated rat adrenal medulla cells. Morphometry of numerical density and electron probe X-ray quantitative microanalysis were adopted to measure the alterations in the number and calcium content of chromaffin granules in adrenal medulla cells during the agonist treatment. Secretion of epinephrine was detected by the high performance liquid chromatography (HPLC). It was found that the Ca content of the isolated rat adrenal medulla chromaffin granules dropped significantly after a 10-min incubation with the agonists, whereas the number of chromaffin granule decreased slowly during the agonist treatment and the epinephrine concentration raised significantly after a 20-min incubation with the agonists. The decrease of granule Ca content occurred earlier than the increase of epinephrine concentration, suggesting that the calcium released from chromaffin granule may in part account for the induced cell secretion.

A method of comprehensive chemical pattern recognition of Atractylodis Rhizoma was established by GC-MS fingerprint, principal component analysis, cluster analysis and discriminant analysis. A DB-wax column (0.25 mm x 60 m, 0.25 microm) with El ion source and 70 V electron multiplier were used for GC-MS analysis. Using principal component analysis, cluster analysis, and discriminant analysis, 15 common peaks of sample fingerprints for chemical pattern recognition research were analysed. The same results were obtained from the fingerprint, principal component analysis and cluster analysis, which could use to distinguish genuine Atractylodes lancea, ungenuine A. lancea and A. chinensis. Thus, this method could be used for the quality control and comprehensive evaluation of Atractylodis Rhizoma.

OBJECTIVETo investigate the anti-inflammation and anti-oxidation effects of recombinant human CuZn superoxide dismutase(rhSOD) on acute lung injury (ALI) induced by meconium aspiration in rats.
METHODS1 ml/kg of 20% human newborn meconium suspension was intratracheally (IT) administrated to induce the model of ALI in 32 male Sprage-Dawley rats, and the animals were then randomized to 4 groups: 3 treatment groups with IT administration of 5, 10 and 20 mg/kg rhSOD dissolved in 1 ml/kg saline and the control group with IT administration of 1 ml/kg saline. The animals were killed after 24 h of treatments. The measurements included lung tissue wet/dry ratio, broncho-alveolar lavage fluid (BALF) protein, BALF protein/plasma protein (pulmonary permeability index, PPI),lung myeloperoxidase (MPO) and superoxide dismutase (SOD) activity, nitric oxide (NO) and 8-isoprostane levels. Lung injury score was also evaluated.
RESULTSCompared with the control group, pulmonary MPO activity, NO and 8-isoprostane levels were significantly decreased and SOD activity was markedly increased in all rhSOD treatment groups (P<0.05 or 0.01). Compared with the rhSOD 5 mg/kg group, pulmonary 8-isoprostane level was further low in the rhSOD 20 mg/kg group(P=0.01). Lung injury score was decreased in rhSOD 20 mg/kg group (P<0.05). But there were no statistically differences in lung wet/dry, BALF protein and PPI among all groups.
CONCLUSIONThe results suggest that a single IT dose of 5,10 or 20 mg/kg rhSOD can prevent lung damages in rats with ALI following meconium aspiration.

OBJECTIVETo study clinical outcomes of Chinese medidine fumigation and massage therapy for the treatment of knee stability and functional recovery after anterior cruciate ligament reconstruction operation,and to explore the effect on tendon-bone healing.
METHODSTotal 50 patients were divided into two groups: the control group (normal rehabilitation therapy group),the treatment group (Chinese medicine fumigation and manipulation group). There were 25 patients in the control group, including 16 males and 9 females, who were treated with isometric muscle training, with the gradually enlarging amplitude of flexion and progressive loading of bearing training for knee recovery. There were 25 patients in the treatment group, including 15 males and 10 females,who were treated with the conventional rehabilitation therapy combined with Chinese medicine fumigation and massage therapy. The Chinese herbs named as Haitongpi decoction was steamed by a special equipment to fumigate the knee after operation; Based on the biomechanical parameters of the ligament reconstruction, the massage therapy was designed to control the degree of the knee flexion and release the adhesion for early recovery of knee functions. The Lysholm knee function evaluation system was used, and MRI examination was performed to measure the change in width of ligament tunnel in femur and tibia to evaluate the safety and stability of the treatment.
RESULTSLysholm system showed that two groups both had improving results from the 1st month after operation to the 3rd month (treatment group, F=36.54, P<0.05; the control group, F=28.12, P<0.05), and the results of the treatment group was better than that of the control group at the observation point (the 1st month, t=0.105, P<0.05; the 3rd month, t=5.361, P<0.01). There was no difference between the two groups when evaluating the bone and tendon healing 3 and 12 months after operation (P>0.05), indicating that Chinese rehabilitation therapy was a safety treatment without the influence on the loosing of tendon.
CONCLUSIONChinese medicine fumigation and massage therapy can early improve the knee function after the anterior cruciate ligament reconstruction operation without the disturbance of the knee stability.
