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.

To assess the effects of resuscitation with oxygen or room air on the cardiac circulation and the activity of superoxide dismutase (SOD) in a hypoxic newborn piglet model. Methods Newborn piglets(1.6-2.5 kg) were randomly assigned into three groups:control group (n=8) with no hypoxic insult;room air group (n=12) resuscitated with room air for 240 min after 120 min hypoxia;and oxygen group (n=12) resuscitated with 100% oxygen for 30 min followed by 210 min with room air after 120 min hypoxia. Blood gas analysis, blood pressure and hemodynamic parameters were recorded at 0, 10, 30, 60, 120, 180 and 240 min of resuscitation. The activity of superoxide dismutase (SOD) in the left ventricle was measured at 240 min of resuscitation using enzyme method . One-way analysis of variance, two-way analysis of variance measured repeatedly and Student-Newman-Keuls test were applied as statistical methods. Results Severe metabolic acidosis, hypotension and hypoxemia were caused by hypoxia.(1)Arterial oxygen partial pressure(PaO2):At 10 min of resuscitation, PaO2 of control group, room air group and oxygen group was (67±4), (78±12) and (409±42)mmHg(1 mmHg=0.133 kPa) (F=580.19, P<0.01). At 30 min of resuscitation, PaO2 of the three group was (68±3), (79±15) and (342±62)mmHg(F=173.67;P<0.01). PaO2 of oxygen group was higher than room air group and control group (10 min:q=42.51 and 39.28, 30 min: q=23.17 and 21.67, all P<0.05). There was no statistical significance between the room air group and control group. (2)Cardiac output(CO):At 240 min of resuscitation,CO of control group, room air group and oxygen group was(181.6±33.8), (150.9±70.1) and (103.6±53.6) dl/(min·kg) (F=4.82, P<0.05). CO of oxygen group was lower than control group (q=4.25,P<0.05). There was no statistical significance between oxygen group and room air group, neither was between room air group and control group (all P>0.05). (3)Arterial oxygen content (CaO2):At 10 min of resuscitation, CaO2 of control group, room air group and oxygen group was(87.0±16.1), (76.9±13.2) and (102.2±15.9) ml O2/dl (F=8.64, P<0.01). At 30 min of resuscitation, CaO2 of the three group was(87.5±14.9), (79.9±11.3) and (100.1±16.7) ml O2/dl (F=5.98, P<0.01). At 10 min of resuscitation, CaO2 of oxygen group was higher than control group and room air group (q=3.14 and 5.85, all P<0.05). At 30 min of resuscitation, CaO2 of oxygen group was higher than room air group (q=4.85, P<0.01), but there was no statistical significance between oxygen group and control group (q=2.71, P>0.05). (4)Oxygen delivery (DO2): At 10, 30, 60, 120, 180 and 240 min of resuscitation, there were no statistical significance among DO2 of control group, room air group and oxygen group [10 min:(16.5±3.3), (15.7±9.9) and (16.9±4.2)L O2/(kg·min), F=0.10;30 min:(16.2±4.1), (15.1±5.5) and (14.5±3.3) L O2/(kg·min), F=0.38;60 min:(16.1±4.2), (14.9±4.0)and(13.3±3.8)L O2/(kg·min), F=1.28;120 min:(15.5±3.7),(15.6±6.1)and(13.4± 4.6) L O2/(kg·min), F=0.66;180 min:(15.4±3.1), (15.3±9.3) and (11.9±5.0) L O2/(kg·min), F=0.97;240 min:(14.7±3.4), (13.4±6.7) and (9.3±5.2) L O2/(kg·min), F=2.84;all P>0.05]. (5) SOD activity in the left ventricle:At 240 min of resuscitation, SOD activity of control group (n=6), room air group (n=8) and oxygen group (n=8) was (289±107), (210±75) and (142±61)U/mg protein, F=5.75, P<0.05]. SOD activity of oxygen group was lower than control group (q=4.79, P<0.01). There was no statistical significance between oxygen group and room air group, neither was between room air group and control group(q=2.58 and 2.39, all P>0.05). Conclusions Despite higher oxygen content in the blood, resuscitation with oxygen is not beneficial to recovery from metabolic acidosis in newborn hypoxic piglets. Oxygen supplementation does not increase oxygen delivery but reduces SV compared to resuscitation with room air. Resuscitation with oxygen may impair the oxidative stress defense.
