Breast reconstruction after radical mastectomy significantly improves the patient' s quality of life and has become an important part of comprehensive treatments. However, there are a number of reconstruction problems. The choice of breast reconstruction after breast cancer should be considered in general. Immediate reconstruction is not superior to breast-conserving surgery, while immediate reconstruction is superior to delayed reconstruction, and choices vary between implant reconstruction and autologous reconstruction. In short, breast reconstruction should be based on the radical principle with balance of beauty.

Objective To evaluate the clinical application of automated urine formed elements analyzer and/or urine dipstick analyzer for examination of urinary formed elements in screening urinary tract infection (UTI). Methods 148 fresh midstream clear-catch urine samples from the UTI patients and 284 fresh midstream clear-catch urine samples from non-UTI subjects were selected. Bacteria culture was performed for bacterial colony counting and identification. Bacteria counts ( BACT), yeast-like fungus and WBC were performed by UF-looOi automated urine formed elements analyzer. Leukocyte esterase test (LEU) and nitrite test (NIT) were performed by URISYS 2400 urine dipstick analyzer. We evaluated data obtained from urine dipstick analyzer, UF-1000i and combination of UF-1000i with urine dipstick analyzer and the results was compared with those obtained from quantitative bacterial culture. Then we evaluated the sensibility, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. Results Among the 148 patients with UTI, the positive rate of the quantitative bacterial culture was 73.6% (109/148), the positive rate of LEU and NIT detected by dipstick test 26. 4% (39/148).There was significantly statistical difference between bacterial culture and strip test(χ2 = 55.68 ,P < 0. 05 ). The positive rate of urine flow cytometry by UF-1000i with either positive of BACT and WBC was 91.2%(135/148), which was higher than the positive rate of the quantitative bacterial culture. There was significant difference between two methods (χ2 = 14. 70, P < 0. 05 ). The positive rate of anyone positive among BACT, WBC, LEU and NIT was 94. 6% (140/148) when detected with combination of dipstick test and UF-1000i, which was higher than the positive rate of the quantitative bacterial culture. And there was significant difference between two methods (χ2 = 20. 45, P < 0. 05 ). The sensitivity of dipstick test was low (26. 4% ,39/148 ), and specificity was high ( 99. 3%, 282/284 ) . The sensitivity, specificity, positive predictive value, negative predictive value of BACT detected by UF-1000i in diagnosing urinary tract infection were 92. 6% ( 137/148 ), 39. 8% ( 113/284 ). 44. 5% ( 137/308 ) and 91.1% ( 113/124 ), respectively. If the dipstick test was combined with UF-1000i, the sensitivity, negative predictive value, specificity, positive predictive value and accuracy were 98.0% ( 145/148 ), 97.1% ( 100/103 ). 35.2% (100/284) ,44. 1% (145/329) and 56. 7% (245/432), respectively. Conclusions The combination of urine dipstick test and automated urine formed elements analyzer UF-1000i plays an important role in early diagnosis of UTI. And it has significant value in diagnosis of UTI, especially for the patients with negative bacterial cultures of urine sample.

Objective:To investigate the effects of mucosal strengthening treatment on preventing recurrence of closedvarices. Methods: In 264 patients with esophageal varices obliteration by banding ligation and sclerotherapy, of 136 patientswere gone on to treat with strengthening mucosa, and 128 patients without strengthening treatment. All patients had beenobserved out of hospital for 1-13 years. Results: There were no recurrence and rebleeding of esophageal varices in the groupwith strengthening treament. But in the group without strengthening treatment, 25 patients (19. 5%) had isolated or strip-like varices with red colour signI small veins grew thick and part of mucosa appeared clear hyperaemia in 21 patients(16.4% ); 6 patients (4.7% ) rebleeded. There were significant differences between two groups (P

Objective To investigate the efficacy of the bioactive artificial vertebrae of a nano- hydroapatite crystals and polyamide 66 composite(n-HA/PA66)to restore the height and architecture of thoracolumbar burst fracture.Methods From December 2003 to February 2006,38 patients(29 males and 9 females)with a mean age of 35.6 years(17-63 years)were treated surgically through anterior ap- proach for decompression and implanted with the bioactive artificial vertebrae of n-HA/PA66 composite to reconstruct the structure of the thoracolumbar burst fractured vertebra.Results All the patients were successfuly followed-up for an average of 8 months,ranging from 6 to 21 months.The bioaetive artificial vertebrac of n-HA/PA66 composite were fused with the receptor bone 3-4 months after operation.The neu- rological function of the patients was restored partially or completely.The thoracolumbar spine was stable during physical examination and the height of thoraeolumbar burst fractured vertebrae that had been restored did not changa during the follow-up.Conclusions Our results show the bioaetive artificial vertebrae of n-HA/PA66 can restore the height and structure of thoracolumbar burst fractured vertebrae and reconstruct the structure of the tboraeolumbar vertebrae effectively,indicating that the bioaetive artificial vertebrae of n- HA/PA66 can be used extensively in clinical spinal surgery.

Objective The detection of malignant lymphoma with invasion in liver and spleen using PET/CT has not been well documented in the literature. This study aimed to investigate the usefulness of PET/CT in this regard and to compare it with plain CT. Methods Forty-one pathologically confirmed malignant lymphoma patients with liver and spleen invasion were recruited into this study. Among all patients, there were 38 non-Hodgkin's lymphoma (NHL), 2 Hodgkin's lymphoma (HL) and 1 gastric mucosa associated lymphoma. PET/CT imaging was recorded 1h after injection of 296～444 MBq 18F-fluorodeoxyglucose (FDG). Results (1) There were 30(30/41) patients with liver invasion, including hepatic nodules, mass and portal nodes. The mass was large to invade surrounding liver parenchyma. (2) There were 23(23/41) patients with spleen invasion. The spleen was enlarged and demonstrated diffused hyper-metabolism. (3) Other invasion included: lung (n=13), cortical bone and marrow (n=12), stomach (n=9), pleural (n=6), and subcutaneous soft tissue (n=5) and so on. Conclusion PET/CT could accurately diagnose the invasion in liver and spleen of malignant lymphoma, which was of potential role on the diagnosis and staging of lymphoma.

BACKGROUNDBudd-Chiari syndrome (BCS) is characterized by liver sinusoidal congestion, ischemic liver cell damage, and liver portal hypertension caused by hepatic venous outflow constriction. The aim of this research was to investigate the clinicopathological features of BCS-associated hepatocellular carcinoma (HCC) and explore its surgical treatment and prognosis.

METHODSClinical data from 38 patients with BCS-associated HCC who were surgically treated in our hospital from July 1998 to August 2010 were retrospectively analyzed. The clinicopathological features and prognosis of patients with BCSassociated HCC and surgical treatment for BCS-associated HCC were investigated.

RESULTSCompared to the patients with hepatitis B virus (HBV)-associated HCC, the patients with BCS-associated HCC showed a female predominance, and had significantly higher cirrhosis rate, higher incidence of solitary tumors, lower incidence of infiltrative growth, higher proportion of marginal or exogenous growth, lower rate of portal vein invasion, and higher degree of differentiation. Median survival was longer in patients with BCS-associated HCC (76 months) than in those with HBV associated HCC (38 months). Of 38 patients with BCS-associated HCC, 22 patients who received combined surgery mainly by liver resection plus cavoatrial shunts exhibited hepatic venous outflow constriction relief, while the other 16 patients only underwent liver resection. The combined surgery group had significantly longer survival and lower incidences of post-operative lethal complications (P < 0.05). Multivariate analysis showed that relief of hepatic venous outflow obstruction was a protective factor for survival of patients with BCS-associated HCC, whereas portal vein invasion was a risk factor.

CONCLUSIONSBCS-associated HCC has a more favorable biological behavior and prognosis than HBV-associated HCC. For patients with BCS-associated HCC, tumor resection accompanied with relief of hepatic venous outflow obstruction can reduce the incidence of complications and extend survival.
