Objective To discuss the curative effect and clinical significance of sclerosing foam agent in the treatment of chronic venous diseases (CVD) with incompetent perforating veins.Methods 65 cases of C4,C5,C6 CVD (a total of 84 limbs) underwent foam sclerotherapy closure for incompetent perforating vein.Patients were followed-up for 3 months,ultrasonography was used to observe the closure of perforating veins and the curative effect.Results 7 patients (9 limbs) were lost to follow-up,all with grade C4.In the 66 (C4,C5) limbs,pigmentation significantly subsided in 45,partial regression in 9,no change in 2.In the 9 limbs with grade C6,complete healing of ulcer in 5,partially healed in 3.Ultrasound observed satisfactory perforating vein closure.Conclusion Foam sclerotherapy closure for incompetent perforating vein has satisfactory effect,with good short-term curative result.

A 56-year-old man with 1-year history of palpitation, heat intolerance and sweating, was diagnosed as thyrotropin (TSH) -secreting pituitary adenoma based on the symptoms of hypermetabolism, enlarged thyroid gland, inappropriately increased serum TSH concomitantly elevated plasma thyroid hormones and a pituitary tumor demonstrated on magnetic resonance imaging. Long-acting octreotide formulation was administered at a dose of 20 mg intramuscularly. Tumor volume shrinkage and improvement of thyroid function was achieved after a single drug injection; and the thyroid function returned to normal in 28 days. It is suggested that long-acting octreotide formulation might be used as a routine therapeutic approach prior to pituitary surgery, which may enhance the effectiveness of surgery and postoperative recovery.

AIM: The effect of low dose radiation (LDR) with different doses of X-rays on apoptosis and its related gene P53 expression were studied in spermatogenic cells of male Kunming mouse testis. METHODS: The different kinds of spermatogenic cells were separated using density gradient centrifugation and their apoptosis was measured by flow cytometry. At meantime, P53 protein and P53 mRNA was measured with immunohistochemical SABC and in situ hybridization, respectively. RESULTS: The apoptosis in all kinds of spermatogenic cells induced by LDR had a remarkable regularity. When the doses were 0 025 and 0 05 Gy, spermatogone apoptosis was domaint. With the increase in irradiation dose (0 075-0 2 Gy), spermatocytes also showed an apoptotic change, but the apoptotic percentage of spermatogonia was significantly higher than that of spermatocytes. Moreover, the apoptosis of spermatids and spermatozoa scarely occurred after LDR. P53 protein expressed in spermatogonia and spermatocytes in varying degrees, and the former was significantly higher than that of the latter after LDR. With the increase in irradiation dose, P53 protein expression showed a upregulated tendency, but that of spermatids and spermatozoa scarcely occurred. P53 mRNA primarily expressed in spermatids and spermatocytes when the dose was 0 025 Gy. With the increase in irradiation doses (0 05-0 2 Gy), that of spermatogonia also showed an enhancement. P53 mRNA expression in spermatogonia and spermatocytes showed a remarkable dose-effect relationship. CONCLUSION: The apoptosis of spermatogenic cells was selectively induced by LDR of X-rays, which had remarkable the dose-effect and time-effect relationships. The mechanism of the selective apoptosis in spermatogenic cells by LDR is closely related to the upregulation of P53 .

BACKGROUND: A new method, i.e., heparin slow-release stent implantation combined with myocardium drilling, is discovered for myocardial revasculadzation, which remarkably improves myocardial perfusion. OBJECTIVE: To investigate the effect of heparin slow-release stent implantation combined with myocardium drilling on myocardial regeneration of pigs with acute myocardial infarction.METHODS: Anterior descending coronary of pig was ligated to induce myocardial infarction model, which was randomly divided into control and implantation groups, with 6 pigs for each group. Self-made borer was used in the implantation group to drill two transmural channels (3.5 mm diameter) on epicardium. A heparin slow-release stent was fixed in the transmural channel. Following intravenous injection, BrdU was used to label DNA duplication so as to observe stromal cell-derived factor-1 (SDF-1) mRNA expression, myocardial perfusion, newborn yocardium, and heart function prior to and following implantation. RESULTS AND CONCLUSION: As compared with control group, SDF-1 expression was enhanced in the implantation group at 6 weeks after stent implantation (P < 0.001), perfusion mass defect percentage was significantly decreased (P < 0.001), ejection fraction of left ventricle was increased (P < 0.05), newborn myocardium was increased (P< 0.001), and survival myocardium in the ischemic region was increased (P < 0.001). The results demonstrated that heparin slow-release stent implantation combined with myocardium drilling could repair damaged myocardial cells and improve heart function through increasing SDF-1 expression and myocardial perfusion.

Objective To investigate the high mobility group box chromosomal protein-1 (HMGB1) levels in patients with acute pancreatitis (AP); and to study the relationship between the serum level of HMGB1 and the severity of AP. Methods The patients' serum HMGB1 concentrations were determined right after admission, 24, 48 hour after admission. The levels of HMGB1 were measured by ELASA kit and its relationship with the severity of AP was analyzed. 20 healthy adults were treated as the control group. Results At the time of admission, and 24, 48 hours after admission, the serum HMGB1 levels in AP patients were (8.05 + 1.60 ), ( 8.04 ± 1.39 ), ( 8.25 ± 1.56) ng/ml, respectively, which were significantly higher than that in the healthy control [ ( 2.20 + 0.57 ) ng/ml, P ＜ 0. 01]. There were 35 patients with severe acute pancreatitis (SAP) and 27 patients with mild acute pancreatitis (MAP). The HMBG1 levels in patients with SAP were (7.99 + 1.69) ,(8.12 ± 1.40), (8.13 ± 1.34) ng/ml, and they were (8.12 + 1.52), (7.92 +1.40), (8.39 ± 1.81 )ng/ml in patients with MAP, and the difference between the two groups was not statistically significant. Conclusions The serum HMGB1 level in AP patients was significantly higher than that in healthy controls, but it was not related with the severity of AP.

Background:Dexamethasone can protect mice against the acute inflammatory liver injury by inhibiting innate immune cell function. However,the roles of T cell in this protective effect remain unknown. Aims:To investigate the regulatory effect of dexamethasone on T cell immune response in acute inflammatory liver injury. Methods:Six male C57BL/ 6J mice were randomly divided into 2 groups. One hour before induction of acute inflammatory liver injury by lipopolysaccharide, dexamethasone 5 mg/ kg and PBS were given intraperitoneally in experimental group and model group,respectively. All the mice were sacrificed 12 hours after model construction. The clinical score and liver function parameters were assessed;splenic mononuclear cells were isolated for measurements of T cell activation,as well as cytokine expression,secretion, and transcriptional factor expression for different T-cell subsets. Results:Clinical score and serum levels of transaminase were significantly lower in experimental group when compared with the model group. Meanwhile,percentage of CD44 +CD62L - T cells(i. e. activated or memory T cells)from spleen was significantly decreased in experimental group. Among splenic T cell population,expression and secretion of IFN-γ,a Th1-type cytokine,was decreased;expression and secretion of IL-4,a Th2-type cytokine,percentage of regulatory T cells(Treg cells),and ratios of Th2 / Th1 and Treg/ Th1 were increased;transcriptional factor specific for Th1 cells was down-regulated,and those for Th2 and Treg cells were up-regulated. Conclusions:Dexamethasone inhibits T cell activation and directs the reciprocal T cell lineage differentiation (repressing Th1 cell differentiation,promoting Th2 and Treg cell differentiation),which may contribute to the protection against acute inflammatory liver injury.
