Forty-three cases of malignant tumors with metastases to serous cavites were treated by interventional chemotherapy under ultrasound guidance and monitoring. 43 cases (83 injections) were all successfully operated and followed up. After peritoneoclysis, besides the common side effects of chemotherapyie nausea and vomiting, 3. 8% of the patients had abdominal pain and 75. 5% had abdominal distention. No complication of hemorrhage, infection, drug leakage or organ injury oceurred. It is suggested the method is safe easily to be used especially for the intracavitary chemotherapy of malignaant tumors and deserves to be widely employed.

Objective To investigate the association of serum adiponectin and tumor necrosis factor alpha (TNF-α) with endothelial damages in metabolic syndrome (MS) patients. Methods One-hundred and five patients diagnosed as MS were recruited as cases and 37 subjects without characteristics of MS were recruited as controls. The cases were divided into two groups according to the level of serum von Willebrand factor (vWF) :normal endo-thelial functional MS group (57 patients) and abnormal endothelial functional MS group (48 patients). Serum adi-ponectin concentration was measured by enzyme-linked immanosorbont assay (ELISA). Serum TNF-α concentration was measured by radioimmunoassay (RIA). Results The concentration of serum adiponectin in normal subjects (10.5 mg/L [SD:3.2]) was significantly higher than both that of normal endothelial functional MS group (7.9 mg/L [SD :2.2]) and abnormal endothelial functional MS group (6.5 μg/L [SD :2.5]) (P < 0.05). The concen-tration of serum TNF-α in normal subjects(0.17 μg/L [SD :0.04]) were significantly lower than that of normal en-dothelial functional MS group (0.19 μg/L [SD:0.05]) and abnormal endothelial functional MS group (0.23 ng/mi [SD: 0.06]) (P< 0.05). The level of serum adiponectin were negatively correlated with TNF-α(r=- 0.555, P < 0.01). Logistic regression analysis results showed that high level of TNF-α was a risk factor of endo-thelial damages (OR = 20.649, P = 0.035), whereas high level of serum adiponectin protected against endothelial damages (OR = 0.340,P=0.006). Conclusions Low level of serum adiponectin and high level of serum TNF-α may correlate with endothelial damages in MS patients.

18F-2-fluro-D-deoxy-glucose (18F-FDG) is used by positron emission tomography/computed tomography (PET/CT) examination as an imaging agent,by observing the uptake of the agent of the lesion to determine its metabolism,and make a diagnosis.It can provide anatomical and functional at the same time,not only qualitative but also position and can significantly improve the accuracy of diagnosis.Currently PET/CT has been widely used in the clinical aspects of the differential diagnosis of benign and malignant tumors,prognostic assessment and so on.The property of pleural effusion is important to the treatment and prognosis of the disease.

Objective To analyze the influence of dexamethasone in the hypotonic-induced volume-sensitive chloride currents in human trabecular meshwork cells,and to investigate the possible mechanism of volume-sensitive chloride channels(VACC)in the glucocorticoid-induced glaucoma(GIG)cases.Methods The human trabecular meshwork cells were seeded in 35 mm diameter plastic petri dishes,so that they could grow in monolayer.The cultured cells were divided into normal cell culture medium group and dexamethasone 1 d,3 d,7 d groups.The chlorine current density values of the cells in four groups were recorded respectively by the whole-cell patch-clamp technique. The differences among groups were compared.Results In normal group,after hypotonic stimulation,under+100 and-100 mV voltage clamp,the outward and inward current density values of the trabecular cells were (19.94±0.87) and (-6.53±0.41)pA/pF.In dexamethasone 1 d,3 d,and 7 d groups,under the same condition,the outward and inward current density values of the trabecular cells were (19.39 ± 1.40)and (-6.42 ± 0.28)pA/pF, (17.97±2.35)and (-5.82±0.94)pA/pF,(17.16±1.16)and (-5.65±0.43)pA/pF.The trabecular cells cultured with dexamethasone for 1 d had lower outward and inward current density values under hypotonic stimulation compared with normal group,but there was no significant difference (P>0.05).The trabecular cells cultured with dexamethasone for 3 d and 7 d,when compared with normal group,had significantly lower outward and inward current density values under hypotonic stimulation (P<0.05 ). Conclusion Dexamethasone could reduce the volume-sensitive chloride current in trabecular meshwork cells,which would affect trabecular meshwork cell volume adjustment.This would possibly cause the increase of the aqueous humor outflow resistance among GIG cases.

Objective To investigate the influence of intravenous infusion by double-lumen peripherally inserted central catheter (PICC)on continuous dynamic central venous pressure(CVP)monitoring.Methods In the patient undergoing the double-lemon PICC,continuous dynamic CVP monitoring was performed by a lumen and the intravenous infusion was conducted by another lu-men.Whether the simultaneous venous infusion affecting the values of continuous dynamic CVP monitoring was observed.Results Intravenous infusion through double-lumen PICC had no influence on simultaneously continuous dynamic CVP monitoring (P>0.05),which could influence the values of CVP monitoring when simultaneously using the intravenous infusion pump(P<0.05). The speed of pumping fluid had no influence in a shout time(10 min),with significant difference(P>0.05).The CVP values could recovered to the status before infusion when continuously infusing after stopping using the infusion pump.Compared with before in-fusion,the CVP values after stopping intravenous infusion had no obvious change(P>0.05).Conclusion Intravenous infusion by double-lumen PICC has no influence on continuous dynamic CVP monitoring.But simultaneously adding infusion pump has certain influence on the CVP monitoring values.
