Objective To evaluate the efficacy of surgical retrieval of testicular spermatozoa,and to present the preliminary results of the retrieved testicular spermatozoa used in intracytoplasmic sperm injection (ICSI) for treatment of non obstructive azoospermic infertility. Methods Forty nine cases of non obstructive azoospermia underwent open testicular biopsy and diagnostic testicular sperm extraction (TESE).Those who had sperms in diagnostic TESE underwent ICSI at least 3 months later. Results Sperms were detected in diagnostic TESE in 12 cases (24.9%). The testicular volume,FSH level and testicular pathology did not accurately predict the presence or absence of sperm in testes.Seven (87.5%) of 8 cases had sperm in re TESE, which were used in their ICSI cycles,resulting in 3 clinical pregnancies. Conclusions The diagnostic TESE should be performed to determine the presence or absence of testicular spermatozoa in testicular failure before ICSI,and the surgically retrieved testicular spermatozoa can be adopted in ICSI for treatment of non obstructive azoospermic infertility.

Objective To explore the relationship between the overexpression of P glycoprotein (P GP) multidrug resistance (MDR) gene in the epileptic patient's peripheral blood lymphocytes and the drug resistance of the intractable epilepsy Methods This is a prospective, observational study. First, the overexpression of P GP MDR in 85 epileptic patients' (M 39, F46,overage age 24 years) peripheral blood lymphocytes were investigated by using immunocytochemistry (ICT) or flow cytometer (FCE). Then, patients were given a single or a combining of two antiepilepstic drugs which they did not received before (including carbamazepine, valproic acid, phenobarbitone,phenytoin), when the single drug was not effective in observing the clinical efficacy Results In FCE study group, results showed that the 11 patients with overexpression of P GP MDR in the epileptic patient's peripheral blood lymphocytes became tolerant to antiepileptic drugs. Eighteen out of 32 patients without overexpression of P GP MDR are effective. In the ICT study group, it is effective that there are only 2 out of the 22 patients with overexpression of P GP MDR. Seven of 12 patients without overexpression of P GP MDR are effective Conclusion It is suggested that the overexpression of MDR in the intractable epileptic patient's peripheral blood lymphocytes might be a significant drug resistance marker. The sensibility of ICT method should be better than the FCE,though the latter may be more accurate.

Objective:To explore the association of tumor associated macrophages (TAM) with tumor invasiveness, metastasis and prognosis in cardia carcinoma tissues.Methods:The cancer tissues and pericarcinomatous tissues of 100 patients with cardia carcinoma who underwent D2 radical operation in the First Hospital of Putian City from January 2014 to January 2015 were collected. M2-type TAM was marked with CD163. The tissue microarray was made and the expression of CD163 in microarray tissues was detected by using immunohistochemistry. The median number of CD163 positive cells in all cancer tissues was taken as the cut-off value. The patients with the mean number of CD163 positive cells ≥ the cut-off value were those with high TAM infiltration, and vice versa. The association of TAM infiltration with clinicopathological features and prognosis was analyzed, and Cox proportional hazards model was used for multivariate analysis of survival.Results:The positive cell median number of CD163 in cardia carcinoma tissues was higher than that in adjacent tissues [the median number ( P25, P75): 32/high power field (HP) (16/HP, 46/HP) vs. 6/HP (4/HP, 11/HP)], and the difference was statistically significant ( Z = -35.044, P < 0.01). There were 48 cases in low invasive group (< 32/HP) and 52 cases in high invasive group (≥32/HP). The proportion of patients with high TAM infiltration in serosa and extraserosa was higher than that in mucosa and muscle [60.9% (39/64) vs. 36.1% (13/36)], and the proportion of patients with high TAM infiltration for patients with lymph node metastasis was higher than that for patients without lymph node metastasis [61.8% (42/68) vs. 31.3% (10/32)], and the proportion of patients with high TAM infiltration for those with TNM stage Ⅲ-Ⅳ was higher than that for those with TNM stage Ⅰ-Ⅱ [64.4% (38/59) vs. 34.1% (14/41)], and the differences were statistically significant (all P < 0.05). The median overall survival time of high TAM group was shorter than that of low TAM group [24.00 months (95% CI 17.25-43.50 months) vs. 62.00 months (95% CI 34.00-68.00)], and the difference in overall survival was statistically significant (χ 2 = 18.137, P < 0.01). Lymph node metastasis ( HR = 0.301, 95% CI 0.105-0.862, P = 0.025), TNM staging ( HR = 8.404, 95% CI 2.810-25.133, P < 0.01) and TAM infiltration level in cancer tissues ( HR = 4.277, 95% CI 2.372-7.712, P < 0.01) were independent influencing factors for overall survival of patients. Conclusions:TAM plays an important role in the invasion and metastasis of cardia carcinoma and can be used as an independent predictor of biological behavior and prognosis in cardia carcinoma.

Tumor genesis and development often result from deregulation of important biological pathways at the gene expression level. Although there has been much work focused on searching gene sets using gene expression data or other prior information, proper statistical testing of the gene sets is still an open question. Most studies have expanded the testing method of a single gene into the gene sets. Parametric statistical analysis of gene sets ( p-SAGE ) was presented for determining the significant gene sets or pathways associated with a phenotype of interest. The method was applied to brain tumor experiments to identify many gene sets. Some of the newly discovered gene sets were related to signal transduction and immunity. This simple and effective method gives useful biologically meaningful results.
