Objective To study the imaging characteristics of vesical leukoplakia under the cys-toscope imaging system. Methods The characteristics of vesical leukoplakia were observed under the cystoscope imaging system in 556 cases. After anti-infection treatment to these patients, the chan-ges of the characteristic under the cystoseope imaging system were re-observed and compared before and after treatment. SPSS 11.0 software package x2 teat for statistical analysis was used. Results Under the cystoscope imaging system, there were four different imaging manifestations in the 556 pa-tients. These were, from mild to severe, congestive type in 42 cases, spots type in 56 cases, thin macular type in 399 cases and thick macular type in 59 cases. One type could transform to another af-ter anti-infection treatment. When reexamination by the cystoscope, 131 cases got improved, 304 cases had no changes and 121 cases were aggravated. Statistical analysis showed the transformation among the 4 types had significant difference (x2 = 130.92, v=6, P<0.001). From congestive type to spots type, thin macular type and thick macular type, after anti-infection treatment, the ratio of improved cases decreased gradually, however the ratio of aggravated cases and cases without changes increased gradually. Conclusion Vesical leukoplakia could be classified into 4 types initially: congestive type,spots type, thin macular type, thick macular type. The different clinical treatments should be provid-ed.

Objective To investigate the curative effect between liver resection combined with microwave ablation during operation and simple liver resection in the treatment of primary liver cancer.Methods From January 2005 to December 2013,a total of 84 patients diagnosed as primary liver cancer in our hospital were collected and divided into combination group(42 cases) and simple group(42 cases) according to the surgical method.Combination group were treated by combining liver resection with microwave ablation during operation,simple group by simple liver resection.Results The intraoperative blood loss for combination group was (323.9 ± 93.1) ml and simple group was (524.5 ± 119.2) ml,P ＜ 0.05.postoperative tumor recurrence rate for combination group was 14.2％ and simple group was 33.3％,P =0.040.1-,3-,and 5-year survival rate for combination group was 96.5％,67％ and 51％,and simple group was 84％,49.5％ and 36.5％,P =0.036.The differences of the above parameters between the two groups were statistically significant.The operation time for combination group was (177.7 ± 30.7) min and simple group was (165.1 ± 29.5) min,P =0.058.The postoperative hospital stay for combination group was (15.5 ± 3.7) d and simple group was (14.0 ± 4.0) d,P =0.068.The changes of ALT,AST,ALB,TBIL on the first postoperative day and the incidence of postoperative complications (including bile leakage,fever,pleural effusion,blooding,abdominal infection and some others) between the two groups had no statistical significances (P ＞ 0.05).Conclusion The curative effects of liver resection combined with microwave ablation during operation are superior to pure liver resection in the treatment of primary liver cancer.

OBJECTIVETo investigate the protective effects of Jiedu Tongluo injection on cerebral edema induced by focal lesion of cerebral ischemia/reperfusion, the hydrous content of brain and the expressions of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin and MMP-9 in rats.

METHODThe model of brain middle cerebral artery ischemia/reperfusion was established by the thread approach. After 24 hours of reperfusion, cerebral edema formation was determined by the hydrous content of brain. The permeability of blood brain barrier was evaluated based on the leakage of Evans blue. Enzyme-linked immunoadsordent assay (ELISA)was used to examine the expression of ICAM-1, VCAM-1, E-selectin. The expression of MMP-9 was measured by immunohistochemistry.

OBJECTIVETo explore the reason, key diagnosic point and therapeutic method of the incisions fat colliquation or infections at early stage after operation of lumbar disc herniation.

METHODSFrom July 2007 to May 2012, clinical data of 11 patients with incision fat liquefaction or early infection after lumbar discectomy were retrospectively analyzed. There were 5 males and 6 females with an average age of 43.1 years, and the mean time of incisions fat colliquation or infection was 5 days and a half after operation. The main clinical features included local wound pain aggravating, fervescence, fresh seepage in the wound, and blood inflammatory index increased, etc. The wound could heal at the first treatment stage or not was an evaluation standard of curative effect.

RESULTSAll patients were followed up with an average period of 21 months. The wounds of 10 cases healed at the first stage without recurrence and complications. In 1 case infected by staphylococcus aureus, distal part of the wound present local red, swelling and with wave motion at 2 months after operation, staphylococcus aureus infection was confirmed after puncture and bacterial culture, and 1 thrum was found after local incision. The wound healed after change dressings for 1 week, without recurrence after followed up for 13 months.

CONCLUSIONPreventing the risk factors before operation, minimizing invasive technique during operation reasonable antibiotics application for the lumbar operation reguiring placement objects, and correctly handling with wound after operation could prevent and reduce the incidence of incisions fat liquefaction or infection after operation of lumbar disc herniation. For incision fat liquefaction or infection, early diagnosis, debridement, VSD negative pressure irrigation and drainage, to choosing sensitive antibiotics according to the results of drug sensitivity, may contribute to wound early healing and decrease complication.

Objective:To investigate the prognosis of cT3 and the subgroups of low rectal cancer patients who underwent neoadju-vant chemoradiotherapy (CRT) and evaluate whether all patients with cT3 low rectal cancer should undergo CRT. Methods:A total of 223 patients with cT3 low rectal cancer treated in the Department of Colorectal Surgery of Fujian Medical University Union Hospital from January 2008 to December 2012 were divided into neoadjuvant chemoradiotherapy group (CRT group) (115 cases) and no neoad-juvant chemoradiotherapy group (nCRT group) (108 cases) according to whether the patients underwent CRT. Afterward, the patients were retrospectively divided into three subgroups (mrT3a, mrT3b, and mrT3c) according to the proposed criteria of the Radiologic Soci-ety of North America (RSNA) by measuring the depth of mesorectal invasion (DMI) (DMI<5, DMI=5-10, and DMI>10 mm). The prog-noses of the two groups and their subgroups were compared. Results:The CRT and nCRT groups revealed no significant differences in the 3-year disease-free survival rate and the local recurrence rate for all the mrT3 patients (78.2%vs. 71.9%, P=0.608;4.4%vs. 8.5%, P=0.120) and mrT3a patients (82.4%vs. 81.8%, P=0.837;5.8%vs. 5.9%, P=0.658). On the contrary, for the mrT3b patients, the CRT and nCRT groups revealed significant differences in the 3-year disease-free survival rate (84.4%vs. 42.4%, P=0.032) and local recurrence rate (0.0%vs. 18.2%, P=0.014). For the mrT3b,c patients, the CRT and nCRT groups revealed no significant difference in the 3-year dis-ease-free survival rate (72.8%vs. 42.4%, P=0.060) but revealed a significant difference in the local recurrence rate (2.4%vs. 18.2%, P=0.021). COX regression analysis was utilized for 3-year disease-free survival, DMI and circumferential resection margin (CRM) were significant in the univariate analysis. Additionally, the multivariate analysis indicated that CRM is an independent impact factor (OR=2.249, CI 1.067-4.742, P=0.033). Conclusion:CRT can improve the prognosis of patients with mrT3b,c low rectal cancer but may not significantly influence the prognosis of patients with mrT3a and CRM-negative low rectal cancer;surgical treatment can be performed in these patients without CRT.

Objective To investigate the diagnostic technique of Alport syndrome(AS)by immunohistochemical staining of type Ⅳ collagen ? chains on paraffin-embedded renal sections.Methods Renal biopsies were obtained from 2 patients with autosomal recessive form of AS,2 female patients and 2 male patients with X-linked dominant form of AS and 2 patients with hematuria(1male and 1 female).AS was diagnosed according to symptoms,family history,pathology,immunofluorescence staining of type Ⅳ collagen ? chains on renal and skin biopsies and gene analysis.Normal portions of nephrectomized kidneys from 2 patients with renal tumor were used as controls.Type Ⅳ collagen ? chains were stained by two-step immunohistochemistry staining method on paraffin-embedded renal sections.Three antigen retrieval methods including autoclave heating,pepsin digestion and proteinase were investigated to find the best antigen retrieval method for type Ⅳ collagen ? chains.The findings were compared with those examined by immunofluorescence staining on fresh frozen sections.Results By immunohistochemistry staining,type Ⅳ collagen ?3 and ?5 chains showed continuous linear pattern along glomerular basement membrane on sections from the controls and the hematuria patients,intermittent linear pattern for X-linked dominant female AS patients,negative for X-linked dominant male AS patient.For patients with autosomal recessive AS,the staining of type Ⅳ collagen ?3 and ?5 chains were negative on glomerular basement membrane,but ?5 chain was positive on glomerular capsules and partial tubular basement membrane.The results were the same as those examined by immunofluorescence staining.Conclusion AS can be diagnosed by immunohistochemistry staining of type Ⅳ collagen on paraffin-embedded renal sections,which is a new technique for diagnosis of AS in China.
