Objective To prepare a monoclonal antibody(McAb) against Trichinella spiralis (T.s) adult and study its protective immunity. Methods BALB/c mice were immunized with soluble antigens of 3 day adult of T.s. Immnuized spleen cells of BALB/c mice were fused with myeloma cells sp2/0. The hybridoma culture supernatant was isotyped by the Ouchterlony double diffusion technique and the specificity of the McAb was determined by immunoblotting. The protective immunity of the McAb was detected after challenging the mice by the intravenous way. Results A McAb against T.s adult was obtained. The titer of culture fluid and ascetic fluid was 1∶6 400 and 1∶204 800, respectively. This McAb was identified as IgM. Western blotting results showed this McAb can be used to identify 40 000 protein of adult worm, muscle larvae and newborn larvae of T.s. No cross reactions with antigens of Ascaris suum Goeze, Taenia solium Linnaeus, Echinococcus granulosus and Schistosoma were oberserved. The number of muscle larvae was decreased by 55.63% when giving McAb to mice intravenously. Conclusions A species specific McAb against T.s adult was established and its protective immunity was identified. This McAb can be used as a powerful tool in screening Trichinella vaccine candidates.

Objective To investigate the influent factors on normal intraabdominal pressure (IAP) and establish the IAP regressive equation. Methods The IAPs of 106 hospitalized patients were determined through monitoring the bladder pressures. The relationship between IAP and 14 factors including age, gender, height, weight, body mass index (BMI), previous and recent abdominal surgical history, reasons for admission,complications and their quantities were analyzed,respectively Results The mean IAP of the hospitalized patients was 5.5 mm Hg with a range from 0.4 mm Hg to 12.8 mm Hg. The difference among IAPs of different grades of BMIs had statistical significance ( F =5.550, P 0.05). Conclusion Normal IAP is possibly influenced by gender and BMI,and it is individually different.

Objective To investigate the correlation of serum concentrations of interleukin(IL)-6,IL-10 and tumor necrosis factor(TNF)-α and the prognosis of sepsis in children.Methods Fifty-seven septic patients in PICU were enrolled in the study,of whom 44 patients survived(sepsis survival group),13 patients died(sepsis dead group).Another 65 cases of non-sepsis patients served as control(non-sepsis group).The critical illness score,the number of damaged organs,and serum levels of IL-6,IL-10,TNF-α,IL-6/IL-10,TNF-α/IL-10 in each group were compared.Results The critical illness score was decreased and the number of damaged organs was more in sepsis dead group than those in non-sepsis group and sepsis survival group.Compared with non-sepsis group and sepsis survival group,the expression of IL-6 and IL-10 increased,TFN-α/IL-10 ratio significantly decreased in sepsis dead group(P ＜ 0.05),but the difference between the sepsis survival group and non-sepsis group was not statistically significant(P ＞ 0.05).The serum levels of TNF-α and IL-6/IL-10 ratio showed no significant difference among three groups(P ＞ 0.05).Conclusion In sepsis patients,the serum concentrations of IL-6,IL-10 are higher and the TNF-α/IL-10 ratio is smaller,the prognosis is worse.

Objective To investigate the clinical value of transanal endoscopic microsurgery (TEM) for the treatment of elderly patients with colorectal adenoma.Methods Totally 21 patients with colorectal villous adenoma underwent TEM from Dec.2007 to Sep.2010.The distance of adenoma from the anal verge was 4-20 cm (average 8.9 cm) and tumor size was 1.1-3.5 cm (average 1.9 cm).There were 12 cases with tubular adenoma and 9 cases with villous adenoma according to pre-operative diagnosis by colonoscopy and endoanal ultrasonography (EUS).Appropriate position and posture were dictated by the location of the tumor under general anesthesia.A special rectoscopy was inserted into the anus with CO2 insufflation to keep the rectum open.Under the stereoscopy and lapaoscopy-type instruments,the tumor was completely resected (submucosal or full-thickness excision) using a 5 mm ultrasonic dissector.The operative wound was closed with intra-lumen continuous sutures.Results The tumor was completely removed with negative resection margins in all the 21 patients (submucosal excision in 12 cases and full-thickness excision in 9 cases).The operating time was 40-100 min (average 76 min) and the intraoperative blood loss was 10-80 ml (average 50 ml).The post-operative stay was 2-10 d (average 4.5 d).The postoperative pathological stages were pT0 in 16 cases and pTia in 5 cases.The postoperative pathological diagnosis were tubular adenoma in 12 cases,villous adenoma in 9 cases,low-grade intraepithelial neoplasia (IN) in 5 cases and high-grade IN in 5 cases.Follow-up checkups in the 20 patients for 2-20 months (average 11 months) revealed no local recurrence.Conclusions TEM is safe and effective with little complication for the treatment of elderly patients with colorectal adenoma.Pre-operative EUS is very important for TEM.

Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.
