Objective To investigate the effect of the prescription of Yiqiyangyin Huoxuehuayu on the mice model with viral dilated cardiomyopathy by examining the levels of serum ?-IFN.Methods Replicated the animal models of early viral dilated cardiomyopathy by injecting the CVB3m virus to the peritoneal cavity of the Balb/c mice.Two hundred and ten Balb/c mice were divided into 4 groups at random:blank group,model group,high and low dose traditional Chinese medicine group.The blank group has 30 mice.The other three group has 60 mice each.The mice of high dose traditional Chinese medicine group and low dose traditional Chinese medicine group were treated with the prescription of Yiqiyangyin Huoxuehuayu.The change of pathomorphology in the cardiac muscle tissue,the rate of death,the weight change and the cardiac weight index were observed after 4 weeks of the treatment.At the same time,ELISA method was used to exam the levels of serum ?-IFN.Results The prescription of Yiqiyangyin Huoxuehuayu can induce the expression of serum ?-IFN in the mice with viral dilated cardiomyopathy.The mean level of serum ?-IFN of the high dose traditional Chinese medicine group and low dose traditional Chinese medicine group were significantly higher than that of the model group.Conclusions The prescription of Yiqiyangyin Huoxuehuayu can inhibit the viral replication and regulate the immunologic function.

Ojective To study the application and the effect of extrathoracic minimally invasive surgery on the patients with mediastinal mass. Methods The therapeutic result of 6 cases of mediastinal mass resected through minimal extrathoracic approach were retrospectively reviewed. Results 6 patients underwent successfully operation and recovered smoothly without any complication or operation death. A following up period lasting two years showed that no recurrence or metastasis occurred. Conclusions Extrathoracic minimally invasive surgery has the advantages of minimal invasion, quicker recovery and complete resected tumor. It may substitute the classical thoracotomy and could obtain the same therapeutic in the selective cases.

Objective To compare the values of classic thoracotomy (CT), subaxillary mini thoracotomy (SAMT), and video-assisted thoracoscopic surgery (VATS) in the treatment of pneumothorax. Methods Postoperative parameters of 3 groups (a total of 78 patients with pneumothorax)-Group CT, Group SAMT, and Group VATS-were compared retrospectively. Results Recurrent numbers of the 3 groups were 1, 1, 0, respectively. Among the 3 groups, the Group CT had the longest drainage time ((4 1?3 1) days) and hospital stay ((11 8?4 6) days), the most drained fluid ((585 0?564 4) ml) and the maximum of Dolantin requirement ((71 7?42 2) mg) ( F =8 087, 41 191, 11 126, 12 528, respectively; P =0 001,

Objective To enhance the understanding of chest primitive neuroectodermal tumor (PNET) and improve the results of management. Methods The results of 10 cases of chest PNET, which had been surgically treated and pathologically confirmed from 1999 to 2004 were retrospectively analyzed. Results There were 6 intrathoracic tumors, 2 in the chest wall, 1 in the pericardium, and 1 in the posterior mediastinum. Two intrathoracic tumors were completely resected, 2 partially resected, tumor and the involved lung were removed in 2 cases. Two had tumor with the affected ribs removed and the chest wall reconstructed. Tumor and the invaded pericardium were removed in 1 case. The PNET in the posterior mediastinum, invading into spinal canal as a bell tumor, was excised by the thoracic surgeon cooperating with neurosurgeon. There was no hospitalization death. All the specimens demonstrated positive reaction to CD99 and negative to LCA. 4 cases received postoperatively adjuvant chemotherapy, 4 radiotherapy and chemotherapy, the other 2 cases had none adjuvant therapy. 7 patients died during 6 years of follow-up, with 9 to 27 months survival. 3 patients are alive and have over 12 months survival so far. Conclusion PNET is an aggressive and invasive malignant tumor with poor prognosis. Difficulties exist in diagnosis. Besides common microscopic examination, pathological histology and immunochemistry, even electron microscopic examination may be required in differential diagnosis. Complete removal of tumor and involved tissue plays an important role, postoperative adjuvant therapy, including radiotherapy or combination with chemotherapy, may prolong survival. Modalities that are more effective should be developed to improve the treatment results.

Objective To evaluate the effect of surgical trauma on the cognitive function and expression of hepcidin and ferroportin 1 (FP1) in hippocampus in aged rats.Methods One hundred male Sprague-Dawley rats,aged 18 months,weighing 400-500 g,were randomly divided into 2 groups with 50 rats in each group:control group (group C) and surgical trauma group (group ST).The rats were anesthetized with chloral hydrate,but underwent no operation in group C.The rats Were anesthetized with chloral hydrate and underwent 30 min of modified exploratory laparotomy in group ST.Ten rats were chosen from each group at 24 h after operation and the cognitive function was assessed using Morris water-maze test for 6 consecutive days.Ten rats were sacrificed on 1st,3rd,5th and 7th days after beginning of Morris water-maze test and brains were removed for determination of hepcidin and FP1 expression in hippocampus by PCR and Western blot.Results Compared with group C,the escape latency was significantly prolonged,the time of staying at the original platform quadrant and frequency of crossing the original platform were decreased on 3rd,4th and 5th days after beginning of Morris water-maze test,and the expression of hepcidin was up-regulated and the expression of FP1 was down-regulated at each time point in group ST (P ＜ 0.05).Conclusion Surgical trauma can decrease the cognitive function in aged rats and the mechanism may be related to up-regulation of hepcidin expression and down-regulation of FP1 expression in hippocampus.

AIM To study the nephrotoxicity of various doses of Guangfangji . METHODS Normal Wistar rats were given 1, 5 and 10 g?kg -1 of Guangfangji respectively. Renal pathology and function were observed. RESULTS Rats given 1 g?kg -1 of Guangfangji for 8 weeks showed normal renal function and histology Rats given 5 g?kg -1 of Guangfangji significantly increased 24 hour urinary protein excretion Tubular degeneration and interstitial edema was observed Blood urea nitrogen (BUN) and serum creactinine (Scr) remained in the normal range BUN and Scr increased significantly in the group given 10 g?kg -1 of Guangfangji for 4 weeks The tubulointerstitial abnormalities were more severe in the group given 5 g?kg -1 of Guangfangji CONCLUSION Longterm use of pharmacopoeial dose of Guangfangji shows no harm to the kidney.Renal injury may occur if relatively large dose of Guangfangji is given and the period of treatment using this drug is relatively longer

Objective To detect the expression of long non-coding RNA (lncRNA) CCAT1 in human papillary thyroid cancer, and to observe the effect of CCAT1 down-regulation on the invasion and migration of human papillary thyroid cancer.Methods The expression of CCAT1 was detected in human normal thyroid Nthy-ori 3-1 cells and human papillary thyroid cancer TPC-1 cells.CCAT1 siRNA plasmid was transfected into TPC-1 cells.The effect of CCAT1 down-regulation on cell invasion and migration was observed by Transwell chamber assay and scratch test, and the expressions of BRAF, MUC15 and RKIP proteins were detected by Western blot.Results The level of CCAT1 in human papillary thyroid cancer TPC-1 cells was significantly higher than that in human normal thyroid Nthy-ori 3-1 cells.CCAT1 down-regulation significantly inhibited the invasion and migration of TPC-1 cells.The Transwell invasion assay revealed that the number of migrated TPC-1 cells in the CCAT1 down-regulation group was significantly lower than that in the control group.The scratch test showed an increased distance between cells in the CCAT1 down-regulation group compared to the control group, suggesting a reduced cell motility.The expressions of BRAF and MUC15 proteins were decreased in the CCAT1 down-regulation group, while that of RKIP protein was increased.Conclusions The expression of CCAT1 in papillary thyroid cancer cells is significantly higher than that in normal human thyroid cells.Down-regulation of CCAT1 in papillary thyroid cancer cells may inhibit the cell invasion and migration by regulating the expression of BRAF, MUC15 and RKIP proteins.

BACKGROUND:Conventional dynamic hip screw or artificial joint replacement can be used to treat unstable intertrochanteric fracture in aged patients. It remains unclear whether we should select one-stage replacement or remedial joint replacement after failture, and there is no unified standard globaly. OBJECTIVE: To observe the outcomes and prognosis of one-stage artificial joint replacement for unstable intertrochanteric fracture in aged patients. METHODS:From April 2008 to October 2011, 21 patients with unstable intertrochanteric fracture in aged patients were repaired with one-stage artificial joint replacement at the Second Department of Orthopedics, Changji Prefecture People’s Hospital. Among 21 patients, 1 patient previously combined with avascular necrosis of the femoral head and traumatic arthritis received biological artificial total hip replacement. Three cases were subjected to standard bone cement bipolar artificial femoral head replacement. 17 cases underwent biological bipolar artificial femoral head prosthesis replacement. Al artificial joint, internal fixation material and accessory joint replacement surgical instruments were purchased outside China. Al patients were folowed up regularly. Hip joint function was assessed by Harris hip score. RESULTS AND CONCLUSION: Al operations were completed by the same group of physicians. Operation time was 30-60 minutes, averagely 42 minutes. Incision length was 8 to 15 cm, averagely 11 cm. Average intraoperative blood loss was 50-300 mL, averagely 150 mL. The number of transfusion cases was 13. 1.5 U blood was transfused averagely in each patient during hospital stay. One 76-year-old patient combined with hypertension, coronary heart disease and diabetes suffered from sudden death due to acute myocardial infarction at 9 days after replacement. B ultrasound revealed venous thrombosis of calf muscle of double lower extremities at 3 days after replacement. No complications such as prosthetic loosening, sinking, infections and thrombosis were detected. Except 1 case died, the other 20 cases received folow-up for 6-49 months. Harris hip score was 73±4 before discharge and 82±6 during last folow-up. These data confirm that effects of one-stage artificial joint replacement for unstable intertrochanteric fracture in aged patients are affirmative, but the number of case is stil less, and deserves further investigations. We suggest that in patients with conformed indication, one-stage artificial joint replacement can be the first choice.

Purpose To analyze the high-frequency sonographic images of lymph nodes in mesenteric lymphadenitis of different ages. Materials and Methods 139 children with mesenteric lymphadenitis (study group) and 60 normal children (control group) were divided into 1 to 5 years, 6 to 10 years and 11 to 15 years group, the characteristics of high-frequency ultrasound sonographic images were analyzed, accuracy of longitudinal diameter (L), transverse diameter (S), aspect ratio (L/S) and color Doppler blood flow signal classification for the prediction of mesenteric lymph nodes swelling were evaluated using receiver operating characteristic (ROC) curve. Results Mesenteric lymph nodes in the control group appeared as spindle shape with sparse blood flow signals, L, and L/S increased with age increasing (F=4.047, 9.586;P<0.05). Mesenteric lymph nodes in the study group displayed as oval or teardrop-shaped with rich blood flow signals, L, S and L/S did not change significantly with age increasing (F=0.184, 1.084, 2.083; P>0.05). Compared with the control group, blood flow signals were more abundant in all age groups of the study group, L and S were also significantly higher (L:t=-13.798,-12.813,-8.089;S:t= -8.212,-13.172,-9.606, P<0.01), only in the 1 to 5 years group statistically significant difference (t=-3.208, P<0.05) was showed between the two groups. From 1 to 5 years, the sensitivity and specificity for the judgment of lymph node swelling were 95.56%and 100.00%, respectively when using L=9.85 mm as a standard;from 6 to 10 years, the sensitivity and specificity for the judgment of lymph node swelling were 95.59%and 100.00%, respectively when using L=10.25 mm as a standard;from 11 to 15 years, the sensitivity and specificity for the judgment of lymph node swelling were 92.31%and 100.00%, respectively when using S=4.40 mm as a standard. Conclusion High-frequency ultrasound is able to display the location distribution and morphological characteristics of the mesenteric lymph nodes in children, and also to accurately measure the diameters and flow signal distribution of the lymph nodes, thus will provide valuable evidence for the diagnosis of pediatric mesenteric lymphadenitis.

OBJECTIVETo investigate the changes and influencing factors of early postoperative pulmonary function of thoracotomy.

METHODSPre- and early postoperative pulmonary function was studied in 64 consecutive cases with optimal thoracotomy. Pain assessment was done before pulmonary function test, and the chief complaints of patients were recorded after the procedure. The changing curves of pulmonary function were done and the differences associated with groups, surgical styles, pain assessment, epidural analgesia, chief complaint and preoperative conditions were analyzed.

RESULTSPulmonary function was severely lowered to about 40% of the base line on the first day, and it was rehabilitated to about 60% of the base line on the eighth day. There was a greater gradient on the recovery curve on the 3rd and 4th days. Epidural analgesia was able to improve pain relaxation and pulmonary function in some degree. Single-factor analysis showed that postoperative pain, postoperative day and surgical style were the significant influencing factors for early postoperative pulmonary function. By multiple-factor analysis, preoperative pulmonary function, age and postoperative pain were the main factors, while surgical style had only weak effect on it.

CONCLUSIONSEarly postoperative pulmonary function is severely impaired by thoracotomy. It rehabilitate gradually with time. Improvement of preoperative pulmonary function, reducing surgical procedure injuries, especially injury to respiratory muscle system, and enough postoperative pain relief are the most important means that would reduce pulmonary function impairment and consequently reduce postoperative pulmonary complications.
