Objective To compare the therapeutic effect of the combination of ~(99m)Tc-methnetium methylene diphosphunate and colloidal chromic,phosphate ~(32)p with the monotherapies in rats with adjuvant arthritis(AA).Methods In this study,50 Sprague-Dawley rats were randomly divided into five groups with 10 rats in each:normal control group(arthritis induced and treated with the same volume of normal saline via the same administration route),AA control group(arthritis induced with adjuvant and treated with normal sa- line),~(32)p colloid group(arthritis induced with adjuvant and treated with single intra-articular injection of col- luidal chromic phosphate ~(32)p 0.74 MBq and intra-peritoneal injection of normal saline every other clay),~(99m)Tc- MDP group(arthritis induced with adjuvant and treated with intra-peritoneal injection of ~(99m)Tc-MDP 2.5?10~(-3)?g/kg every other day and single intra-articular injection of normal saline),combination group(arthritis in- duced with adjuvant and treated with the combination of the two drugs).The diameter of the left hind ankle, serum levels of turnout necrosis factor(TNF)and interleukin-1?(IL-1?),and the pathological changes of an- kle joints were tested at different time points.Results The diameter of the left hind ankle at week 4 was smaller in the combination group than that of the ~(32)p colloid treatment alone group [(7.11?0.34)mm vs(7.57?0.29)mm,P

Objective To study the clinical features and prevention means of the infection caused by the highly dathogenic avian influenza A(H_5N_1).Method The clinical data which were confirmed to be an H_5N_1 infected case were analyzed retrospectively.Results The patient,16-year-old male,had no unambi guous history of direct contact with diseased or dead poultry before the onset of the disease.After the onset of the disease,chest X-ray showed flake shadow of the right lower lung quickly spread to the whole lung,associated with mediastinum,subcutaneous emphysema,acute respiratory distress syndrome(ARDS)was occurred on the fifth day.Mechanical ventilation is the primary measure in the comprehensive treatment.On the sixth day,Chinese Center for Disease Control and Prevention detected the pharyngeal specimen of the patient by RT - PCR,Real- time PCR method and suggested positive for the A/H5/N1 virus nucleic acid andis01ated the avian flu(H_5N_1) virus.The disease course was 10 days from onset of illness to death.Conclusions Human infection by the highly pathogenic avian influenza A(H_5N_1)is a deadly infectious disease.If the lesions is widespread and associated with ARDS,prognosis is poor.

OBJECTIVETo observe the clinical significance of nitric oxide (NO) and 8-isoprostane (8-isoPG) changes in exhaled breath condensate ( EBC) of acute respiratory distress syndrome (ARDS) patients after treated by Qingfei Decoction (QD).

METHODSTotally 48 ARDS patients receiving mechanical ventilation were equally assigned to the QD treatment group and the control group by random digit table. EBC specimens were collected by modified Ecoscreen breath condensate collector (German JAEGER Company) on the first day and the fifth day after confirmed diagnosis of ARDS. Concentrations of NO and 8-isoPG in EBC were measured by ELISA. The oxygenation index and APACHE II scores were recorded at the same time.

RESULTS(1) The fatality rate in the QD treatment group was lower than that in the control group (8.3% vs 37.5%, P < 0.05). (2) After treatment NO and 8-isoPG concentrations in EBC were lower in the QD treatment group (34.49 ± 5.67 µmol/L, 30.09 ± 7.89 ng/L) than in the control group (39.78 ± 9.27 µmol/L, 35.65 ± 8.90 ng/L; P < 0.05). (3) After treatment improved oxygenation index value was higher in the QD treatment group than in the control group (120.88 ± 35.16 vs 101.50 ± 37.70, P < 0.05). After treatment APACHEII scores was lower in the QD treatment group than in the control group (6.21 ± 3.51 vs 10. 26 ± 4.33, P < 0.05).

CONCLUSIONTreatment of ARDS patients by QD was favorable in controlling inflammation, alleviating lung injury, and improving clinical efficacy.

OBJECTIVETo study the curative effect of postural reduction with instrumental reduction in treatment of flexion-distraction thoracolumbar fractures.

METHODSA retrospective study was performed on 43 patients with single thoracolumbar flexion-distraction fractures admitted from August 2009 to August 2011, included 28 males and 15 females with an average age of 44 years old (34 to 56 years old). All patients were treated with postural reduction with instrumental reduction. The kyphosis (Cobb angle) recovery of injured vertebral height and complication were analyzed. The visual analogue scale(VAS) and com-plications were followed up and recorded.

RESULTSThere was no difference in recovery of injured vertebral posterior height among preoperative, 1 week and 1 year after operation (P > 0.05). There were significantly difference in kyphosis (Cobb angle) and recovery of injured vertebral anterior height between preoperative and postoperative at 1 week (P < 0.05). There was no difference in kyphosis (Cobb angle) and recovery of injured vertebral anterior height between 1 week and 1 year after operation (P > 0.05). VAS significantly improved from preoperative (7.2 +/- 1.2) to (0.8 +/- 0.7) at 1 year after operation (t = 18.47, P < 0.001).

CONCLUSIONPostural reduction with instrumental reduction is effective for thoracolumbar flexion-distraction fractures and it is beneficial to the recovery of vertebral height and saggital alignment.

OBJECTIVETo explore the clinical and physical factors that might give rise to radiation-induced esophagitis in three-dimensional conformal radiotherapy for non-small cell lung cancer.

METHODSTo collect the clinical and physical records and follow-up information of 106 NSCLC patients without undergoing surgery in our hospital. χ(2) test, linear tendency test and analysis of variance were employed to analyze the relationship between occurrence of radiation-induced esophagitis and clinical and physical treatment. Logistic analysis was also used for multivariate analysis.

RESULTSAmong the 47 cases of radiation-induced esophagitis, 31 cases were of grade I, 11 of grade II, 5 of grade III, and with a total occurrence rate of 44.3% (47/106). Radiation-induced esophagitis was correlated with Karnofsky scores, radiation sensitization and tumor location (χ(2) = 11.30, 8.45, 7.67, P < 0.05). Radiation-induced esophagitis was correlated with the length of irradiated esophagus and average dose of irradiated esophagus (F = 20.82, 83.08, P < 0.001). With the increase of the irradiated volume percentage from V20, V30, V40 up to V50, the occurrence rate of radiation-induced esophagitis was also increased, almost with a linear trend (P < 0.05). Application of all the above factors to logistic model indicated that radiation sensitization,length of irradiated esophagus, average dose and V50 were all statistically significant foactors in the occurrence of radiation-induced esophagitis (OR = 0.321, 2.850, 7.307 and 8.558, P < 0.05).

CONCLUSIONSRadiation sensitization,length of irradiated esophagus, average dose of irradiated esophagus and V50 are independent factors in the occurrence of radiation-induced esophagitis. V50 is of greater importance in the judgement of occurrence of radiation-induced esophagitis.

OBJECTIVETo observe the effect of Yanggan Yishui Granule (YGYSG) on collagen protein I, III, and IV, as well as fibronection (EN) in spontaneously hypertensive rats (SHR), and to explore its possible renal protective mechanisms.

METHODSFourty SHR were randomly divided into four groups, i.e., the model group, the Benazepril group, the low dose YGYSG group, and the high dose YGYSG group, 10 in each group. A normal control group was set up with recruited Wistar-Kyoto (WKY) rats. After 6 weeks of treatment, the expression of collagen protein I, III, and IV, as well as FN in the 5.1 image analysis system.

RESULTSIn the WKY-control group, there was only a small amount of brown particles in the mesenchymal region, the glomerular basement membrane, or the mesangial region. The expression of collagen I, Ill, and IV, as well as EN significantly increased more in the model group than in the normal control group (P < 0.01). After treatment, the expression of collagen I, III, and IV, as well as FN significantly decreased in each treated group, showing statistical difference when compared with the model group (P < 0.01). Besides, decresed expression of collagen I, III, and IV was shown in the low dose YGYSG group and the Benazepril group (P > 0.05). The expression of collagen I, III, and IV could be further reduced in the high dose YGYSG group, showing statistical difference when compared with the Benazepril group and the low dose YGYSG group (P < 0.05, P < 0.01).

CONCLUSIONYGYSG might play an important role in the renal protective effect through reducing the synthesis of renal collagen I, III, and IV, as well as FN, increasing the degradation of renal collagen I, III, and IV, as well as FN, thereby reducing excessive deposition of renal extracellular matrix (ECM).

Objective　To evaluate the technique and clinical outcomes of modified transperitoneal laparoscopic radical prostatectomy.　Methods　A total of 285 patients received the operation with mean age of 67 years (50-76 years) from January 2008 to April 2012.Mean level of PSA was 15.7 μg/L (1.8 -50.0 μg/L),and mean prostatic volume was 44 ml (26 -74 ml). No lymph node or seminal vesicle involvement was found by CT or MR and radionuclide bone scan revealed no metastasis.271 cases were confirmed diagnosis by prostatic biopsy and 14 were detected through pathological studies of TURP specimens.Gleason score ranged from 6 to 8.14 cases were in clinical stage T1b,29 cases in T1c,214 cases in T2 and 28 cases in T3a.Transperitoneal approach and modified technique involving bladder neck dissection,nervesparing technique and vesicoureteral anastomosis were applied on patients.　Results　Mean operative time was 105 min (55 -150 min).Mean intraoperative estimated blood loss was 240 ml (50-800 ml).Rectal injures occurred in 2 cases and were repaired under laparoscopy.Drainage tube and urinary catheter were removed 48 -72 h and 5 -8 d postoperatively.Postoperative hospital stay was 7 d (5 - 11 d).Positive surgical margin was present in 58 patients.Mean follow-up time was 29 months (3 -50 months).Complete continence were found in 208 patients immediately after catheter removal.68 patient recovered continence within 3 months and 9 patients remained incontinence 3 months after surgery. Normal erection presented in 42 of the 57 cases with nerve-sparing.　Conclusions　Transperitoneal laparoscopic radical prostatectomy is safe and efficient.Higher efficiency and lower complication rate have been achieved through modified laparoscopic technique involving bladder neck dissection,nerve-sparing technique and vesicoureteral anastomosis.

Objective To discuss the treatment of ureteropelvic junction obstruction by laparoscopic pyeloplasty. Methods A retrospective review of consecutive laparoscopic pyeloplasty in 102 patients between September 2001 and December 2007 was performed. The ureterpelvic junction was dissected and the obstruction portion was excised. Anastomosis was then performed through the ureter and the renal pelvis walls with a stent. Results The mean operating time was 120 min and the average blood loss was 80ml. No major complication occurred intraoperative. The drainage was removed in 3-10 days. The average hospital stay was 8.5 days. The stent was kept for 30-60 days. IVU and B ultrasound examination revealed that the hydronephrosis alleviated during the follow-up and no anastomosis stricture occurred. Conclusions Laparoscopic dismembered pyeloplasty could provide lower morbidity, shorter hospital stay, and faster convalescence. It could be an effective treatment for ureteropelvic junction obstruction.

Objective To evaluate the role of cerebral state index(CSI),burst suppression (BS)and electromyograph(EMG)in monitoring coma/consciousness depth and damage degree of brain. Methods CSM was done in 50 cases with brain injury and coma to analyze its relation with physical reflection,auditory evoked potential(AEP),Glasgow coma score(GCS)and Glasgow outcome scale (GOS).Results As scale range meaning from consciousness to deep coma and to brain death,CSI 0- 100 was positively correlated with coma depth,coma score of GCS and physical reflection.CSI changes under invariable ache stimulation in combination with BS and EMG can accurately estimate prognosis and quantify changes of brain function.Conclusions The quantifiable digit of coma/consciousness depth and damage degree in brain function by CSM can attain real time judgment of dynamic evolvement course of coma and objective guide clinical therapy and assure prognosis,as will change absolutely scoring coma/ consciousness depth and prognosis under current state of artificial diversity and lacking objective evi- dences.
