Pit cells (PCs) are hepatic natural killer cells(HNKCs), and play an important role in resisting tumor, resisting virus, regulating hepatocyte growth and differentiation, inhibiting liver fibrosis and so on. In the paper, research progress in liver pit cells is briefly summarized.

Objective To study the CT characteristics of inflammatory pseudotumor of the liver(IPL).Methods 16-slice spiral CT findings of IPL in 16 cases were analysed retrospectively.The CT values of IPLs and the liver tissue surrounding the lesions were measured on plain and contrast-enhanced CT scans.Results Totally 18 lesions in 16 cases were detected by CT,most of them(16 lesions) located in the right lobes of liver.The lesions appeared as low-density,round or round-like,or irregularity in sharp.Dynamic enhanced CT scan showed the lesions no or slight enhancement in arterial phase,slight to moderate enhancement in portal vein phase.A part of the lesions showed ring enhancement surrounding the lesions,nodular or fiber stripped enhancement in the center of lesions,and the branches of the portal vein passesed through the lesions.In enhanced degree of the lesions,there was not statistical difference in arterial phase compared with plain CT scans,but there were statistical differences in portal-venous phase compared with plain scan and arterial phase.In the liver around the lesion,the enhanced degree had statistical difference in artery phase and portal-vein phase compared with plain CT scans.Conclusion Dynamic enhanced CT scan shows that IPL is of hypovascularity,it's of characteristic in the portal-venous phase and delayed phase.

Flail chest is the common chest trauma, which causes abnormal respiration and mediastinal swing affecting the respiratory and circulatory function after injury. Fixation of ribs of flail chest has been used for half a century, methods and equipment of which varied, and domestic and foreign scholars have verified its efficacy in clinical practice. This article summarizes its main great progresses.

Objective To investigate pathogens of hepatitis B virus (HBV) ,hepatitis C virus(HCV) and treponema palladium (TP) current infection situation and trend among voluntary blood donors in Pingdingshan city .Methods The testing results of HB-sAg ,anti-HCV and anti-TP among voluntary blood donors were investigated and analyzed .Results Six-year total positive rates of HBsAg ,anti-HCV and anti-TP were 1 .24% ,0 .55% and 0 .48% ,respectively .Positive rates of HBsAg ,anti-HCV and anti-TP were going downward year after year ,in recent three years especially .Conclusion The initial effects of establishing a safe and fixed voluntary blood donor group have been shown .

OBJECTIVE:To observe the therapeutic effect of compound glycyrrhizin injection on herpes zoster METHOD_S:50 cases of herpes zoster received compound glycyrrhizin injection 60ml q d intravenous drip for 5 days RESULTS:Curative rate was 22% and improving rate 64% with a total effective rate of 86% CONCLUSION:Compound glycyrrhizin has corticosteroid-like action,which could regulate immunologic function and inhibit virus

Objective To observe the effect of oxymatrine on the Absorption of carbohydrate and fat and the activity of peroxisome proliferator activated receptor ? and ?.Methods 64 masculine SD rats were randomly divided into three groups,20 sugar tolerance test,20 triacylglycero Absorption test and 24 oxymatrine effecting on triacylglycero and cholesterin test,and observed the effect of oxymatrine on glycosidase activity,blood sugar and activity of peroxisome proliferator activated receptor ? and ?.Results ① The depressant effect of oxymatrine on the activity of glycosidase was strengthened by the increased dosage.② Oxymatrine could suppress the upgraded level of blood sugar after took amylon and cane-sugar,and inhibit the upgraded level of triacylglycerol after feed by olive oil and hypso-cholesterol,but did not suppress the upgraded level of blood sugar after took glucose and hardly influence the level of high density lipoprotein cholesterol and low density lipoprotein cholesterol.③ Oxymatrine could obviously activate the activity of peroxisome proliferator activated receptor ? and ?,the activity of peroxisome proliferator activated receptor ? and ? increased gradually by the augment of the oxymatrine,and expressed evident dose-response relation.Conclusions Oxymatrine could not only directly inhibit the Absorption of triacylglycerol and depress the elevated level of postprandial triacylglycerol,but also activate peroxisome proliferator activated receptor ?,moreover possess dose-response relation.

Objective To construct health examination system based on network to satisfy the growing demand for businesses management. Methods Through interacting on the system interface with LIS. The use of diagnostic expressions, templates and default values speeded up medical data entry and deposit in scan mode to non -digital medical images. Results The software of health examination information system was developed and the work flow of health examination was reconstructed. Conclusion The physical examination information system can greatly reduce the workload of repeated transcription and entering, and enhance the efficiency of health examination management.

ObjectiveTo investigate the nursing scheme to prevent infection,thromboembolism,accidental shedding during application of permanent deep venous catheter in hemodialysis. Methods28 patients undergoing maintenance hemodialysis from January 2007 to February 2009 were randomly divided into the observation group and the control group with 14 patients in each group.The control group took conventional care only,the observation group was given pertinent nursing intervention.After treatment the number of patients with infection and thromboembolism were compared in both groups. ResultsAll patients were successfully placed catheters.Number of patients with infection,thromboembolism and accidental shedding in the observation group were less than those in the control group.But there was no significant difference in average indwelling time of catheters between two groups. ConclusionsApplication of permanent deep venous catheter in hemodialysis shows good effect,it can decrease the incidence of complication and should be widely applied.
