ObjectiveTo investigate the clinical value and pathological basis of peritumoral hyperenhanced rim (PHR) of renal cell carcinomas (RCCs) on CEUS.MethodsCEUS images of 53 patients with 54 renal tumors (27 RCCs,27 renal angiomyolipomas) were analyzed,and the detection and distribution of PHR were evaluated.HE staining and immunohistochemistry of CD34 were performed in tissue surrounding RCCs (TSR) to observe distribution of psuedocapsule,large vessels,and microvasculars among TSR with different modes of PHR.ResultsPHR was found only in RCCs.PHR distribution between RCCs and angiomyolipomas was statistically different (P<0.05).Using PHR to diagnose RCC,the sensitivity,specificity,positive predictive value,negative predictive value,false positive and false negative was 44.44% (12/27),100% (27/27),100% (12/12),64.29% (27/42),0 (0/27) and 35.71% (15/42),respectively.Pseudocapsule distribution between RCCs with PHR and RCCs without PHR was not statistically different (P> 0.05).There were rich large blood vessels in TSR with PHR in washin and both phases,and few or thimbleful large vessels were found in TSR without PHR in washout phase.Cancer tissue near the boundary (CTNB) of TSR had the highest microvessel density (MVD).MVD differences in different TSR with PHR were statistically different between washin and washout phases,washin and both phases,both phases with PHR and without PHR (P<0.05),but no statistical difference was found between washout and both phases (P>0.05).ConclusionPHR is a highly specific complementary indicator in diagnosing RCC,and it is correlated with rich blood vessels in TSR and (or) a higher MVD value in CTNB.

? AIM: To analyze clinical characteristics and postoperative outcomes after open globe injury.?METHODS: Demographic characteristics ( age, gender, eye trauma, profession, cause of injury and injured part ) , as well as complications and prognosis were analyzed in 152 cases (152 eyes) of open globe injury.? RESULTS: Patients with open globe injury had an average age of 40. 45±38. 32 years old with a 5. 9:1 male-to-female gender ratio. The left-to-right eye ratio was 1. 27:1. Most patients were workers, farmers, or retired. The most common etiologies were scratches, boxing, and falls. Zone Ⅲ was the most commonly injured part. Iridoptosis or iris incarceration, retinal detachment, vitreal prolapse, hyphema or hypopyon, and vitreous hemorrhage were the most common complications. Visual acuity improved in 86 cases postoperatively but ophthalmectomy was still required in 25 eyes.?CONCLUSION: Vision can be improved after surgery in open globe injury. However, patients are usually seriously injured and improvement is minimal, thereby resulting in a great loss to patients and society.

Objective To explore the clinical curative effect of laparoscopic cholecystectomy (LC) in treatment of patients with acute calculouscholecystitis in acute stage. Methods We retrospectively analysed the data of 1353 patients with acute calculouscholecystitis in acute stage who received laparoscopic cholecystectomy in Dept.of General Surgery, The First Affiliated Hospital of Nanyang Medical College and Dept.of Hepatopancreatobiliary Surgery 3,The 2nd Affiliated Hospital of Kunming Medical University from August 2008 to December 2012. Results In 1353 patients, 1316 patients were performed LC successfully (97.27%) . One patient was found with bile duct injury and was cured after Laparoscopic T tube drainage. Two patients were found with postoperative bile leakage, one of them was found with wing hole effusion after removal of the abdominal cavity drainage tube, and was cured after continuous drainage. The operation time was 26-168 minutes, with an average of 47 minutes, the hospitalization time was 3-15 days, with an average of 7.3 days. No incision infection was found . 37 patients were transferred to laparotomy because of common bile duct injury in 2 cases, unclear gallbladder triangle in 23 cases, difficult operation after decompression result from high gall bladder pressure caused by big calculus incarceration in the gallbladder neck in 3 cases, gallbladder gallstone disease in 2 cases, atrophic and vitrified acute cholecystitis and biliary calculus in 2 cases, gallbladder artery bleeding in 4 cases and severe abdominal cavity adhesion in 1 case. Conclusion For patients with acute calculous cholecystitis in acute stage, LC is asafe, effective, and minimally invasive treatment method with quick recovery and low cost, but the operator must be familiar with the anatomy of Calot triangle,and has skilled LC operation skills.

OBJECTIVETo study the relationship between Chinese medical syndrome types and metabolomics of non-small cell lung cancer (NSCLC) patients.
METHODSTotally 120 NSCLC patients were assigned to asthenia syndrome group and sthenia syndrome group, 60 in each group. Meanwhile, 60 cases of benign pulmonary nodules in physical examinations were recruited as the control group. Tumor tissues or benign pulmonary nodules tissues were obtained by thoracoscope. Changes of their metabolites were observed using gas chromatography-mass spectrometry (GC-MS). Their differences were studied using principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA). ROC curve analysis was performed in different metabolic compounds of sthenia and asthenia syndromes groups. The area under the curve (AUC) was calculated to evaluate the sensitivity of diagnosing syndrome types.
RESULTSCompared with the control group, difference existed in 16 compounds. Of them , contents of citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, linoleic acid, oleic acid, lactic acid, inositol were more in the two tumors group than in the control group. Difference existed in 10 compounds between the sthenia syndrome group and the asthenia syndrome group. Of them, citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, lactic acid, and inositol were more in the asthenia syndrome group than in the sthenia syndrome group. Contents of valine, glucose, and glutamine were more in the sthenia syndrome group than in the asthenia syndrome group. ROC curve analyses of different compounds indicated that AUC of lactic acid and glucose was more than 0.8 (P < 0.01); AUC of inositol, choline phosphate, and glycerol phosphate choline was more than 0.7 (P < 0.01); AUC of valine, citric acid, glutamine, alanine, and pyruvic acid was more than 0.6 (P < 0.05).
CONCLUSIONSThere existed certain correlation between CM syndrome types and metabolomics of lung cancer. Lactic acid, glucose, inositol, choline phosphate, glycerol phosphate choline, valine, citric acid, glutamine, alanine, pyruvic acid were sensitive diagnostic compounds, and the first four kinds were most sensitive compounds.

AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.
