Objective To explore the change and clinical significance of plasma levels of thrombomodulin(TM) in children with Kawasaki disease(KD)(n=44) before and after treatmen with intravenous immunoglobulin(IVIG).Methods Enzyme-linked immunosorbent assay(ELISA) was used to detect the plasma levels of TM in children with KD(n=44) before and after treatment with IVIG and in normal control group(n=15),respectively.Children with KD were enrolled from September 2004 to June 2006,one group(n=20) with coronary artery lesions(CALs) and another group(n=24) without CALs.The control were enrolled from heathy children in clinic service.Results The plasma level of TM in KD group before treatment with IVIG was significantly higher than that in control group(P

OBJECTIVETo observe the effect of Bushen Huoxue Recipe (BHR) on inhibiting vascular calcification (VC) in chronic renal failure (CRF) rats by regulating BMP-2/Runx2/Osterix signal pathway, and to explore its possible mechanism.

METHODSThirty SD rats were randomly divided into the normal group, the model group, and the BHR group, 10 in each group. Rats in the model group and the BHR group were administered with 250 mg/kg adenine suspension by gastroagavage and fed with 1.8% high phosphorus forage, once per day in the first 4 weeks, and then gastric administration of adenine suspension was changed to once per two days in the following 5-8 weeks. Rats in the BHR group were administered with BHR at the daily dose of 55 g/kg by gastrogavage in the first 8 weeks, once per day. Equal volume of normal saline was given to rats in the normal group by gastrogavage for 8 weeks. Histological changes in renal tissue and aorta VC were observed by HE staining and alizarin red staining respectively. Levels of calcium (Ca), phosphorus (P), serum creatinine (Cr), blood urea nitrogen (BUN), and intact parathyroid hormone (iPTH) in serum were detected. Protein expression levels of bone morphogenetic protein (BMP-2), Runt related transcription factor (Runx2) , and Osterix were detected by Western blot.

RESULTSHE staining showed that compared with the normal group, disordered glomerular structure, tubular ectasia and dropsy, intracavitary inflammatory cell infiltration, dark brown crystal deposition in kidney tubules, renal interstitial fibrosis, and decreased number of renal blood vessels in the model group. Compared with the model group, normal glomerular numbers increased more, reduced degree of tubular ectasia, decreased number of inflammatory cells, and reduced adenine crystal deposition in the BHR group. Alizarin red staining showed that compared with the normal group, calcified nodes could be found in the model group, with extensive deposition of red particle in aorta. Compared with the model group, calcified nodes were reduced in the BHR group. Compared with normal group, serum levels of P, SCr, BUN, and iPTH significantly increased, serum Ca level significantly decreased, protein expressions of BMP-2, Runx2, Osterix also increased in the model group (P < 0.05, P < 0.01). Compared with the model group, serum levels of P, SCr, BUN, and iPTH levels significantly decreased, serum Ca level significantly increased, protein expressions of BMP-2, Runx2, Osterix also decreased in the BHD group (P < 0.05, P < 0.01).

CONCLUSIONBHD could improve renal function, Ca-P metabolism, and renal histological changes in CHF rats, down-regulate the expression level of BMP-2/Runx2/Osterix signal pathway in vascular calcification of CRF, which might be one of the mechanisms for inhibiting VC in CHF.

Objective To explore the origin and etiopathogenesis of antrochoanal polyp (ACP)based on the clinical data.Methods Twenty-six patients with ACP were included in the study.All the ACP patients were documented by preoperative endoscopy and computer tomographic (CT) scans.All patients were treated under endonasal endoscopic surgery.The relationship between polyp in middle meatus and lesions in the antrum was observed during the surgery.Following surgical removal,the polyps and lesions in the antrum were studied under macroscopy and microscopy.Results Among 26 cases with ACP,17 cases were confirmed by preoperative endoscopic examination that polyp originating from antrum ostium,19 cases showed intimate relationship between the polyp and antrum lesions in CT scan,and 23 cases were found that the polyp originating from the antrum cyst.The pedicle of polyp connected the cyst through autrum ostium,and the polyp existed as a part of capsule wall.Conclusion Based on the data obtained,it is tempting to suggest that the ACP mainly develops from antral cyst,an increase in pressure in cyst forced capsule wall to herniate to middle meatus through the antral ostium,and the continuous herniation and hyperplasy leading to the formation of ACP.

Objective To investigation the pathological characteristics of esophageal squamous cell carcinoma to provide reference criteria for delineating the target area in radiotherapy.Methods Fifty-two patients from the Fourth Hospital of HeBei Medical University underwent resection whom all had been proved to have esophageal squamous cell carcinoma before operation.Chest CT was scanned and transmitted to the 3- dimensional conformal planning system for radiotherapy by VRX-16 scanner.The lesion of esophageal carcinoma was delineated in the 3-dimensional rebuild CT image and the lesion volume was computed by digital rebuild program.Every surgically resected specimen was made into pathologic giant section.The actual size of the specimen was obtained by calculating the size under the microscope with the shrinkage ratio.Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration were observed in the giant section with a microscope and the order of such pathological characteristics were analysed statistically.Results 1.The tumor length by different method of preparation of operated specimens differed obviously.The longest was shown by CT. 2.Multicentric carcinomatous lesion was found in 15(29%)cases out of 52 patients.Proximal to the tumor,the mean distance between the multicentric carcinomatous lesion and the main lesion plus the length of the multicentric carcinomatous lesion was 3.02?1.45cm.Distal to the tumor,it was 2.60?2.44 cm.Severe dysplasia was found in 28 patients.Proximally,the mean distance between the severe dysplasia and the main lesion plus the length of the severe dysplasia was 2.45?1.30 cm.Distal to the tumor,it was 3.24?2.19 cm.Direct intramural infiltration was found in 41 patients,of which the mean length being 2.80?1.52 cm proximally and 2.02?1.51 cm distally. 3.Tumor thrombus was found in 6 patients and lymphoduct infiltration in 36 patients.Direct intramural infiltration was found at higher incidence in specimens complicated with lymphoduct infiltration(86%)and those complicated with tumor thrombus(91%).There were no apparent factors affecting severe dysplasia.The proximal distance to direct intra- mural infiltration was much longer than distally.Conclusions Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration may be observed in esophageal squamous cell carcinoma.Multicentric carcinomatous lesion and direct intramural infiltration are obviously correlated with lymphoduct infiltration.To cover 95% of the microscopic extension,a margin of 5.0 cm is needed proximal to the base of gross tumor volume,and 7.5 cm distal to it.To cover 90% of the microscopic extension,a margin of 4.5 cm is needed proximally,and 5.0 cm distally.

AIM:To explore the diagnosis and treatment methods of radioaction-induced optic neuritis ( RION) through the clinical dates of 17 patients.
METHODS: It was a retrospective case series study. From August 2008 to October 2013, 17 cases (24 eyes) of Rion clinical dates from Chinese PLA General Hospital were studied. The diagnosis methods including visual acuity, pupil, fundus, visual field, fundus fluorescein angiography (FFA), visual electrophysiological testing, and head MRI. To analysis the clinical date of patients with diagnosis of RION by statistical description.
RESULTS: The deterioration degree of vision: 13 eyes were classified as Ⅳ, 9 eyes as Ⅲ, 2 eyes as II. Ten eyes RAPD ( + ) , visual electrophysiology is extinguished. The retina of 5 eyes showed flame hemorrhages and cotton wool spots exudation. Optic nerve head edema in one eye. T1 - weighted MRI enhanced in 19 eyes which showed optic nerve of the intracranial and intratubal segments abnormal changed, optic chiasm and pituitary stalk signal abnormalities and enhancement of the optic nerve. Tortuous optic nerves and rough edges were observed in 5 eyes. Treatment effect: 4 eyes of visual acuity improved, 1 eye from blindness to light perception,1 eye from 0. 08 to 0. 2, 1 eye from 0. 4 to 0. 6,1 eye from 0. 04 to 0. 15, the rest of the cases did not see any improvement.
CONCLUSION: The unique clinical manifestation of RION can provide objective basis for clinical diagnosis in time, but there have not been proven any effective treatments.

OBJECTIVETo observe the clinical efficacy of Huangqi Fuzheng Decoction (HQFZD) in treating recurrent genital herpes (RGH) and its influence on related cytokines in peripheral blood.

METHODSEighty-four patients with RGH were randomly assigned to 3 groups, the treated group treated with HQFZD (31 cases), the control group A (25 cases) treated with Aciclovir, and the control group B (28 cases) treated with Aciclovir plus interferon. The course of treatment was 3 weeks for all. The relapse rate was estimated at 6 months after treatment, and levels of IL-4, IL-10, IL-12 and IL-18 in all patients were detected before and after treatment using double-sandwich ELISA.

RESULTSAll patients were cured after treatment. The relapse rate in the treated group and the control group B was lower than that in the control group A (P < 0.01) but insignificant difference was shown between the former two groups. Before treatment, patients' serum levels of IL-4 and IL-10 were significantly higher while those of IL-12 and IL-18 were lower than the normal range (P < 0.01). The abnormal change aforementioned reversed after treatment in the treated group and the control group B (P < 0.05 or P < 0.01), showing a superior effect to that in the control group A (P < 0.01).

CONCLUSIONHQFZD can reduce the relapse rate of RGH without obvious adverse reaction, and it could also enhance the immunity of the patients.
