OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.
METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.
RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).
CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

Thirteen patients with colorectal lesions underwent laparoscopic surgery from January to December 2019. Before surgery, 5.0 ml autogenous blood was injected under colonoscopy into the inferior margin and opposite sides of the lesion for localization. The operation time,success rate,complications,location efficiency and postoperative pathology were evaluated. The autologous blood tattooing was easily applied for all patients without complication. At laparoscopic surgery,the lesions of all patients were clearly visualized except one obese patients with rectal tumors, because the tumor was located below the retroperitoneal fold. No blood diffusion and leakage,and local inflammatory responses were observed. The surgical margins of all samples were tumor negative. Preoperative tattooing with autologous blood is recommended as an easy,safe and economical procedure for colonoscopic surgery in patients with colorectal lesions.

Objective To investigate the role of pre-chemotherapy hemoglobin and platelet levels in the effect of chemotherapy and prognostic outcome in patients with International Federation of Gynecology and Obstetrics(FIGO) stage Ⅰ b2 - Ⅱb cervical cancer treated with neoadjuvant chemotherapy followed by radical hysterectomy.Methods From January 1999 to December 2010,111 patients with FIGO stage Ⅰ b2 - Ⅱ b who underwent chemosurgical treatment at the department of obstetrics and gynecology in Peking Union Medical College Hospital were reviewed.The median age of patients was 42 years (range:21 -68 years).The median level of prechemotherapy hemoglobin and platelet levels was 127 g/L and 266 ×109/L,respectively.Chemotherapy response was evaluated according to the WHO criteria,including complete response (CR),partial response (PR),arable disease (SD) and progressive disease (PD).Patients who achieved CR or PR were defined as responder.Rates of clinical response were compared with the clinicalpathological variables using chi-square test.Multiple logistic regression was carried out to evaluate the relationship among the probability of achieving an optimal clinical response and the variables.The log-rank test was used to compare the homogeneity of progression-free survival and overall survival functions across strata defined by categories of prognostic variables.The Cox proportional hazard model was used to assess the significance of potential prognostic factors for progression-free survival and overall survival.Results All patients received one to three cycles of chemotherapy.After the neoadjuvant chemotherapy,9 patients achieved CR,77 patients PR,23 patients SD, 2 patients PD.The overall response rate was 77.5%(86/111).By univariate analysis,the clinical response rate was associated with tumor grade( P =0.026),deep cervical stromal invasion ( P =0.029 ) and positive lymph nodes ( P =0.048 ).By multiple logistic regression,deep cervical stromal invasion ( P =0.015 ) and positive lymph nodes ( P =0.031 ) were independent predictors of optimal clinical response.By log-rank test,5-year overall survival rate and 5-year progression-free survival rate were associated with lymph nodes metastases status and lymphovascular invasion ( P =0.000),but not with hemoglobin and platelet levels( P > 0.05 ).By Cox regression model,lymph nodes metastases status and lymph-vascular space involvement ( P < 0.01 ) were independently prognostic factors of 5-year overall survival rate and 5-year progression-free survival rate.Conclusion Pretreatment hemoglobin and platelet levels were neither predictors of clinical response to chemotherapy nor prognostic factors.

The expression of cDNA encoding Tachyleus auti-lipoposaccharide (LPS) factor, which is of interest for use as a potential inhibitor of the common core subunit of Gram-negative bacterial endotoxin. First, the TALF gene was inserted into expression vectors pGEX-4T-2, pET22b and pET28a to construct recombinant expression plasmids. The recombinant plasmids were transformed to E. coli BL21 (DE3) and the expression of TALF was examined. Results show that TALF in pET22b and pET28a vectors can't be expressed. Only the fusion protein GST-TALF was expressed in E. coli BL21 existing as inclusion bodies. From 1 liter of culture, about 4mg of fusion protein GST-TALF with 91% purity was finally obtained. No apparent bactericidal activity and LPS neutralizing activity of the fusion protein GST-TALF were found. After digested with thrombin, the fusion protein GST-TALF exhibited strong bactericidal activity and LPS neutralizing activity.

BACKGROUNDOne stage transanal Soave pull-through procedure (TSPP) is a recent popular operation in the treatment of Hirschsprung's disease (HD). With no visible scar and a short hospital stay, it is well accepted by surgeons and mothers. In the conventional Soave procedure, a long rectal muscular cuff left for anocolic anastomosis might increase the incidence of postoperative enterocolitis and constipation. This study presents a modified transanal Soave pull-through procedure (MTSPP) which includes an oblique mucosectomy and an oblique anastomosis with a short split muscular cuff.
METHODSA review of two groups of HD patients was made: 112 underwent conventional transanal Soave procedure from 1999 to 2001 (group 1) and 140 underwent modified transanal Soave procedure from 2002 to 2004 (group 2). A comparison was made between the two groups on operative data and postoperative complications. The data included: age at the operation, operating time, blood loss, time to feeds and hospital stay, occurrence of postoperative enterocolitis or constipation, need for anal dilatation, postoperative bowel function and perianal skin problems.
RESULTSThere was no significant difference between two groups with respect to age, gender, length of colon resected, operating time, blood loss and hospital stay. However occurrence of postoperative enterocolitis, constipation, anastomotic stricture and time needed for anal dilatation were evidently less in group 2 (MTSPP). The mean operating time in group 1 was (106 +/- 39) minutes with a range of 60 to 170 minutes; in group 2 was (101 +/- 36) minutes with a range of 66 to 190 minutes. The average length of the bowel resected in group 1 was (24 +/- 7) cm, range 15 to 58 cm; in group 2 was (26 +/- 8) cm, range 15 to 70 cm. Two patients, one in each group, required laparoscopic assistance because of long aganglionic colon. Another patient in group 2 required laparotomy because of total colonic aganglionosis. Postoperative complications in group 1 included: temporary perianal excoriation in 34 patients (26 were < 3 months of age), enterocolitis in 21, anastomotic stricture in 11, recurrent constipation in 12, cuff abscess in 1, anastomosis leak in 1, soiling in 3 and rectal prolapse in 1. In group 2 post operative complications included: transient perianal excoriation in 37 patients (30 were < 3 months of age), enterocolitis in 13, anastomotic stricture in 5, recurrent constipation in 6, anastomotic leak in 1, adhesive bowel obstruction in 1 and soiling in 4. Complete bowel continence was found in 97 children (86.6%) in group 1 and in 129 children (92.1%) in group 2 at one year followup after operation.
CONCLUSIONSModified transanal Soave pull-through procedure for HD with oblique mucosectomy and anastomosis and a short split muscular cuff is a safe and feasible operation with low incidence of postoperative complication. It is an encouraging improvement of the conventional transanal Soave pull-through procedure. MTSPP is a preferable choice in the surgery of HD.
