Objective To compare the value of intrarectal filling with water and filling in rubber sheath with water in endoluminal uhrasonography for preoperative staging of rectal tumors. Methods 215 cases of rectal tumors were divided into two groups. 120 cases using the method of filling in rubber sheath with water and 95 cases using intrarectal filling with water were diagnosed with uhrasonography. The results were compared with corresponding pathologic results for the judgment of their accuracy. Results The accuracy for the diagnosis of infiltration depth was 60.0 % in the first group and was 73.7 % in the second. The difference was statistically significant (P <0.05). The accuracy for diagnosis of metastases of perirectal lymph nodes was 82.5 % in the first group and was 80.0 % in the second. The difference has no statistical significance (P >0.50). Conclusion Intrarectai filling with water is better than filling in rubber sheath with water in the diagnosis of infiltration depth of rectal tumors, while there is no difference in the diagnosis of metastasis of perirectal lymph nodes.

[Objective]To investigate the prophylactic effects of intra-articular injection of salvia miltiorrhiza on joint adhesion. [Methods]Twenty-four Japanese male rabbits were randomly divided into 3 groups.All right hind knees were made in this way: the auterior wall of suprapatellar bursae was scraped, the posterior wall of suprapatellar bursae and the infrapatellar fat pad were cut off. Each knee was injected with physiological saline 0.3 ml for group A, sodium hyaluronate injection 0.3 ml for group B, and salvia miltiorrhiza injection 0.3 ml for group C. All right hind knees were immobilized in the extension position with a long leg plaster cast for 4 weeks, and injected weekly.[Results]After 4 weeks, the joint movement range in group B or C was larger than that in group A (P<0.01), and there was no significant difference (P>0.05)compared to group B and group C. The scoring of joint adhesions in group B or C was smaller than that in group A (P<0.01), and there was no significant difference(P>0.05)compared to group B and group C. The scoring of histological changed of the synovial membrane in group B or C was smaller than that in group A (P<0.01), and there was no significant difference(P>0.05)compared to group B and group C.Total collagens content of the synovial membrane in group B or C was smaller than that in group A (P<0.01), while that of group C was less than in group B(P<0.01). [Conclusion]Similarly to sodium hyaluronate, salvia miltiorrhiza can effectively prevent joint adhesions.

This study is to investigate the effects of indirubin on ATP-induced immune responses of macrophages. For this, neutral red dye uptake method was used to test phagocytosis, MTT assay was used for measuring cell death, and reactive oxygen species (ROS) was tested with fluorescent probe DHE. The data showed that extracellular ATP attenuated phagocytosis, induced cell death and increased ROS production, and these effects were restored by pre-treating with indirubin. This result suggested that indirubin blockade the effects of ATP on macrophages, because extracellular ATP-induced effects are dependent on P2 receptors, in particular P2X7 receptors. Furthermore, the effects of indirubin on the activation of P2 receptors were tested, in particular P2X7 receptors. The data showed that indirubin significantly decreased ATP-induced, P2 receptors mediated intracellular Ca2+ concentration ([Ca2+]i) rise and inhibited P2X7 receptor-based ethidium bromide (EB) dye uptake. These results suggested the inhibitory effects of indirubin on the activation of P2X7 receptors, which may underlying the effects on ATP induced ROS production, phagocytosis attenuation and cell death of macrophages.

Objective To discuss the diagnosis and surgical treatment for carotid body tumors (CBT). Methods Retrospective analysis was made on 16 cases of carotid body tumors hospitalized in Shandong Provincal Hospital from January 2003 to October 2010. All patients were diagnosed by digital subtraction angiography, including 3 case of Shamblin type Ⅰ,11 cases of Shamblin type Ⅱ and 2 cases of Shamblin type Ⅲ. Three cases of type Ⅰ and 3 cases of type Ⅱ underwent carotid body tumor resection. Three cases of type Ⅱ underwent carotid body tumor plus external carotid artery resection, 3 cases underwent carotid body tumor plus external carotid artery resection plus carotid artery repairment, 2 cases did carotid body tumor plus external carotid artery resection plus internal carotid artery reconstruction. One of type Ⅲ underwent carotid body tumor plus external carotid artery resection plus carotid artery repairment, and the other one underwent carotid body tumor plus external carotid artery resection plus internal carotid artery reconstruction. Results Diagnosis of CBT was confirmed by pathology in all cases. There was no postoperative death、hemiplegia and blindness. The cranial nerve injury was caused in 7 cases, accounting for 43. 75%. 13 cases ( 81. 25% ) were followed up for 2 to 76 months ( mean 42 months), no tumor recurrence and metastasis was found. Conclusions Digital subtraction angiography (DSA) is important in the diagnosis and therapy of carotid body tumor. Surgical treatment is the choice of therapy for carotid body tumors.

Objective To evaluate the effects of iron dextran or iron sucrose on the stability of fat emulsion in total nutrient admixture (TNA) in pediatric settings.Methods TNA with different intravenous doses of iron sucrose or iron dextran (0.25,0.5,0.75,or 1.00 mg) were prepared,and each dose was prepared 10 bags.The TNAs were stored at 25 ℃ for 3 days,and the stability of fat emulsion was observed by electron scanning microscopy.Meanwhile,the pH and osmolality were also measured.Results The particle sizes of fat emulsions in TNA with different concentrations of iron sucrose or iron dextran at different time points were not significantly different (F =0.32,P =0.7836 ; F =1.73,P =0.1321,respectively).The mean particle size of the fat emulsion in each group was ＜ 0.5 μm within 72 hours.For TNA containing different concentrations of iron,the percentage of particles ＞ 0.5 μm,pH,and osmotic pressure showed no significant difference at different time points (percentage:F =1.47,P =0.3467 ; F =1.04,P =0.4758.pH:F =0.63,P =0.5942 ; F =0.46,P =0.6825.osmotic pressure:F =1.37,P =0.3648 ; F =0.65,P =0.6023).Conclusion The TNA addeded with iron sucrose or iron dextran with an concentrations of ＜ 1％ is stable.
