Brucellosis is a zoonosis with worldwide distribution.There is an upward trend in the incidence of this disease in recent years,and multiple systems and organs are affected.Complication of bone and joint is the most commonly seen of Brucellosis.Although cardiovascular complication is rare,it is the major reason for Brucellosis-related mortality.The author summarized domestic and foreign studies on Brucella endocarditis.

Objective To investigate the expression of vascular endothelial growth factor C(VEGF-C ) in tissue, serum and lymph fluid in esophageal cancer patients, and the relationship between its expression and tumor lymphatic metastasis. Methods Expressions of VEGF-C in 76 cases of ESC was detected by immunohisto-chemical SP method and VEGF-C levels in lymph fluid and serum were assessed by enzyme-linked immunosorbent assay. Results Positive immunostaining of VEGF-C in esophageal cancer tissue was 63.1%,The expression of VEGF-C in tissue was significantly associated with lymph node metastasis and TNM stage ( P<0.01, P<0.05 respectively), but not to patient age, tumor length or differentiation; VEGF-C in lymph fluid is significantly higher than in serum( P<0.05) ; The expression of VEGF-C in lymph fluid end serum were significantly associated with lymph node metastasis( P<0.05). Conclusion There are cliuical significance between VEGF-C expression and lymph node metastasis、TNM stage in tissue of esophageal cancer. The level of VFGF-C in lymph fluid is higher than that in serum, both associate with lymph-node metastasis closely.

OBJECTIVE Approach the cause of esophageal perforation and the analysis of diagnosis, therapy and its outcome in this disease. METHODS We retrospectively review 11 patients of esophageal perforation between1997 and 2004 in our department. There were 9 cases were taken out foreign bodies from their esophageal, another 2 cases haven't been found any foreignbodies and 1 of 2 was caused by iatrogenic reasons. Perforation occurred in the cervical esophagus was 4, and in the thoracic esophagus was 7. Their symptoms were dysphagia or pain, retrosternal-pain, dyspnea, subcutaneous emphysema, fever, hematemesis or melena. RESULTS 7/11 cases visited the clinic during 24 hours after foreign-body occured, 4/11 cases visited after 24 hours and the last visited clinic on 27th day late. Dysphagia was the most common presenting symptom specially with pain in eating, noted in 9 cases (81.8 %); retrosternal-pain and fever were noted in 8 cases (72.7 %), subcutaneous emphysema in 5 (45.5 %), dyspnea in 2 (18.2 %), hematemesis and melena.in 1 (9.1 %). 5 cases were died and the common mortality was 45.45 % (5/11). The mortality in primary repair with surgery treatment was 66.7 % (2/3); the mortality in conservative management was 37.5 % (3/8). The mortality of the perforation in cervical esophagus was 25 % (1/4), in thoracic esophagus was 57.14 % (4/7). The mortality of the visit time in 24 hours was 28.57 % (2/7),and out of 24 hour was 75% (3/4). CONCLUSION Sophageal perforation is usually caused by foreign body or iatrogenic in ENT-Head&Neck surgery. The esophageal perforation will been cured that decided in early visiting, taking away of foreign-boby, the right choice of antibiotic, nutritional support, primary healthy statement of esophagus. We regard that should perform non-operational conservative therapy in the patients who resulted in esophageal perforation except abscess or remain causing by foreign body. And the high risks in mortality of the repairing in surgery should been noticed.

Objective:To summarize the ultrasound features of renal arteriovenous fistula(RAVF)under various ultrasound imaging modes,so as to avoid missed diagnosis of RAVF on initial ultrasound examination.Methods:The clinical data of 6 patients with RAVF,including the ultrasound evidence,the timing of ultrasound diagnosis,the modes of ultrasound diagnosis, and the agreement between ultrasound diagnosis and selective renal arterial angiography,were retrospectively analyzed.Results: 2D ultrasound had 1 case of correct diagnosis,1 case of misdiagnosis and 4 cases of missed diagnosis.Color Doppler and spectral Doppler both had all the 6 cases correctly diagnosed.Ultrasound angiography in 3 cases demonstrated that the contrast agent reached the renal veins earlier than reached the renal parenchyma;large fistula lumen was associated with ischemia of downstream areas.3D ultrasound vividly reflected the structure of fistula lumen volume,and provided us with the profiles of blood signal in fistula at different planes and angles,improving our knowledge of blood flow on the fistula.Conclusion: Ultrasound is the first line screening method for RAVF.Color Doppler plays a decisive role in the diagnosis of RAVF and pulsed spectral Doppler plays a synergetic role and contributes to differential diagnosis.Contrast-enhanced ultrasound may help to discover the abnormality of venous circulation and the ischemic parenehyma area due to shunting.2D ultrasound has a poor diagnostic value and is liable to lead to misdiagnosis and missed diagnosis.

Objective To investigate the expression of vascular endothelial growth factorC(VEGF-C),its receptor3(VEGFR-3) and podoplanin in tissue of esophageal cancer,and the relationship between their expression and tumor lymphatic metastasis.Methods Expression of VEGF-C,VEGFR-3 and podoplanin in 76 cases of ESC was detected by immunohistochemical SP method and lymphatic vessel density(LVD) was calculated.Results Positive immunostaining of VEGF-C in esophageal cancer tissue was 63.1%;the expression of VEGF-C was significantly associated with the depth of lymph node metastasis and tumor invasion(P

Objective:To explore the protective effect of sodium channels antagonists HOE642 on lung ischemia reperfusion and the role of the p38 mitogen activated protein kinase (p38MAPK) signaling pathway in this process.Methods:A total of 36 mice were randomly divided into a sham operation group (SHAM group),a lung ischemia reperfusion group (I/R group) and a lung ischemia reperfusion+HOE642 group (HOE group).The water content was detected by electronic scales,and the lung tissue pathological changes were observed under optical microscope.The inflammatory cytokines including IL-6 and TNF-α were examined by ELISA.The intracellular calcium fluorescence intensity was examined and observed under fluorescence microscope,and the protein expression of p38MAPK was detected by Western blot.Results:Lung water content in the HOE group was lower than that in the I/R group,but higher than that in the SHAM group (both P＜0.05).Lung interstitial edema,hemorrhage,lung tissue inflammatory cells infiltration were significantly alleviated in the HOE group than those in the I/R group,while the injury in the HOE group was aggravated than those in the SHAM group (both P＜0.05).T he IL-6 and TNF-α in lung tissues in the HOE group were lower than those in the I/R group,but higher than those in the SHAM group (both P＜0.05).Intracellular calcium fluorescence intensity in the HOE group was lower than that in the I/R group,but higher than that in the SHAM group (both P＜0.05).The protein expression of p38MAPK in lung tissues in the HOE group was lower than that in the I/R group,but higher than that in the SHAM group (both P＜0.05).Conclusion:HOE642 may exert protective effect on pulmonary I/R injury through regulation of the p38MAPK signaling pathway,resulting in reduction of intracellular calcium ion concentration and calcium overload,and decrease of inflammatory response.

OBJECTIVETo compare the clinical efficacy difference between encircling needling combined with physical factor therapy and simple physical factor therapy for severe pressure sore, and to explore the optimal method for severe pressure sores.

METHODSThirty-four patients with IV-grade pressure sore were randomly divided into an observation group and a control group, 17 cases in each one. Patients in the control group were treated with conventional nursing, ultrasonic wave and short-wave ultraviolet therapy; additionally, the encircling needling was applied in the observation group. All the treatment was given once a day, 5 times a week, and 4-week treatment constituted one session. Totally, two sessions of treatment were performed. Three indices, including the area of pressure sore, 24-h volume of exudates and wound-bed tissue type, were compared between the two groups before and after treatment; the clinical efficacy was evaluated in the two groups.

RESULTSAfter treatment of one session and two sessions, the area of pressure sore, 24-h volume of exudates and wound-bed tissue type were significantly reduced in the two groups (P < 0.01, P < 0.05), which was more obvious in the observation group (all P < 0.05). The total effective rate in the observation group was 76.5% (13/17) after 1 session and 94.1% (16/17) after 2 sessions, which were superior to 35.3% (6/17) after 1 session and 64.7% (11/17) after 2 sessions in the control group (both P < 0.05).

CONCLUSIONEncircling needling combined with physical factor therapy can obviously reduce the pressure sore area and 24-h volume of exudates and improve wound-bed tissue type, which is superior to simple physical factor therapy.
