Objective To explore the histopathological features, immunohistochemical characteristics and clinical manifestation of lymph nodes in patients with cat-scratch disease (CSD). Methods Nineteen cases of lymph nodes of CSD were analyzed by histopathological and immunohistochemical techniques. Results All patients with CSD had a clear history of close contact with cats. The local lymph nodes were punctured swelling. The histopathological characteristics were granulomatous small abscess, lymphocytes and immunoblastic cells growing. CEA (-), EMA (-), CD_ 45 (+), CD_ 20 (+), CD_ 45 RO (+) and CD_ 68 (++) were observed in immunohistochemistry. Conclusion CSD is a self-limited infectious disease caused by cat scratching and biting, its pathogen is bartonella henselae. Its histopathological characteristics, immunohistochemical expressions and clinical history have very important meaning for the diagnosis and differential diagnosis of CSD.

Literatures of study on acupoint functional effect of encephalic region with functional magnetic resonance imaging (fMRI) are collected from the database of China National Knowledge Information (CNKI) and Wan fang database. Analysis and comments are made respectively from the status quo of studies on combination of single acupoint, two acupoints and multiple acupoints under both physiological and pathological conditions. The results show that the corresponding encephalic regions can be specifically activated by acupuncture. And different regions can be activated by different acupoints. However, studies on single acupoint, two acupoints and three acupoints are the major researches carried out at present. It is still lack of observation on effect of commonly-used combinations in clinic. Moreover, the reliability of the research results are also affected by disunity of operations protocol, reinforcing or reducing manipulations, intensity or depth of stimulation and duration of needling retention. Therefore, it is necessary to establish a unified and standard operation protocol to strictly control the bias factors which may affect the result of research in the future, and take patients as the study target as much as possible, so as to further explore the central effect mechanism.

Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

Objective To explore the feasibility of a novel incisionless laparoscopic technique in the treatment of colorectal tumor, and evaluate the preliminary clinical result of this technique. Methods The clinical data of 12 consecutive resected specimens of high located rectal or sigmoid tumor removed by traditional laparoscopic surgery were analyzed to probe the indication of this technique and the first 2 cases received incisionless laparoscopic anterior resection. Postoperative follow up was made to evaluate the clinical feasibilities. Results Among 12 explanted fresh specimens there were 1 adenoma and 3 adenocarcinoma cases in which the key steps of the new technique were successfully demonstrated. In two cases, the bowel above the tumor was cut and the distal end was inverted and pulled through the anus laparoscopically, the tumor along with the bowel resected, the stump pushed hack, and intralumen sigmoidproctostomy fashioned. In these two patients, one of sigmoid cancer and one of large rectal adenoma with focal canceration, the mean operation time was 200 min, mean blood lose was 50 ml, mean bowel function recovery time was 1.5 days. After 13 and 15 respective months fullow up there was no complications nor tumor recurrence. Conclusions Ineisionless laparoscopic surgery, while in line with tumor free principles, has the advantage of safety, cost-effectiveness and being cosmetic in selected cases.

Objective Prostate cancer is one of the most common cancer in males .The article was to investigate the expres-sion and clinicopathological significance of VEGF-C mRNA in prostate cancer , finding the molecular marker for early diagnosis and prognosis assessment of prostate cancer . Methods TaqMan real-time polymerase chain reaction ( PCR) analysis was used to detect the expression of VEGF-C mRNA in 3 prostate cancer cell lines(PC-3, DU145 and LNCap), 32 cases of prostate cancer (Pca) sam-ples and 15 cases of benign prostatic hyperplasia (BPH).Analysis was also made on the correlations of VEGF-C mRNA expression, clinicopathological features and prognosis . Results High levels of VEGF-C mRNA were detected in PC-3 ( 153 .31 ±26 .24 ) and DU145(194.62 ±41.36)compared to LNcap(1.00 ±0.00).The expression of VEGF-C mRNA in prostate cancer tissues was 3.43 folds higher than that in the benign prostatic hyperplasia tissues ([13.67 ±1.95] vs [11.89 ±1.63], P=0.004).The high expres-sion of VEGF-C mRNA in prostate cancer was associated with high Gleason score ( P =0.004 ) and lymph node metastasis ( P =0.015).In patients with high expression and low expression of VEGF-C mRNA, the 3-year survival rate was 12.5%and 40.0%re-spectively(P=0.033). Conclusion The VEGF-C mRNA expression may be related to the biological behavior of prostate cancer .It is suggested that VEGF-C mRNA can be used as a prognostic marker for prostate cancer .
