Objective To investigate the effects of autologous blood transfusion on serum neopterin and IL-2 concentrations after radical gastrectomy. Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes (33 male, 27 female) aged 40-65 yrs weighing 51-70 kg undergoing radical gastrectomy for stomach cancer were randomly divided into 2 groups (n = 30 each):homologous blood transfusion group (H) and autologous blood transfusion group (A). The patients were premedicated with intramuscular diazepam 10 mg and atropine 0.5 mg. Anesthesia was induced with midazolam 0.1 mg?kg-1, fentanyl 5 ?g?kg-1, propofol 1 mg?kg-1 and vecuronium 0.12 mg? kg-1 and maintained with isoflurane inhalation (1 % -2 %) and intermittent i. v. boluses of fentanyl and vecuronium. In group H homologous blood 400 ml was infused during gastro-intestinal anastomosis. In group A 400 ml of blood was removed from radial artery after induction of anesthesia, before surgery. Blood volume was maintained by simultaneous infusion of succinylated gelatin 500 ml. The 400 ml autologous blood was infused also during gastrointestinal anastomosis. Venous blood samples were taken before operation (baseline) , at the end of operation and on the 5th postoperative day for determination of serum concentrations of neopterin and IL-2 (ELISA) Results The two groups were comparable with regard to sex (M/F ratio), age, body weight, duration of operation and total blood loss. The serum concentrations of neopterin and IL-2 were significantly decreased after operation compared to the baseline values before operation in group H (P

Objective To evaluate the precipitating factor,mortality,complications of myasthenia gravis crisis and risk factors of prolonged intubation.Methods Totally 82 case records of patients who had been adimitted for having 87 episodes of myasthenia crisis over a period of 15 years from January 1985 to February 2000 and their age, gender, precipitating factors, complications of intubation, and prolonged intubation factors were retrospectively reviewed. Results In 75% of myasthenic crisis patients having precipitating factors, infection was the most often served as the precipitating factors, and then the wound, fatigue, manopause and delivery came the next, 24% of precipitating factors were related to medication. Nine were identified with independent predictors of prolonged intubation. Among the 82 myasthenia crisis patients, 12 died, with a mortality of 14%.Conclusion The prevention and treatment for intubation complications may be the best way for further shortening intubation time and reducing the mortality.

MicroRNA are endogenous non-coding small RNA composed of approximately 18 - 23 nucleotides, mainly participating in post-transcription gene regulation. More and more data show that miR-21 is over-expressed in many human cancer cells and it was involved in cell differentiation, proliferation and apoptosis, closely related to tumorigenesis and the development of carcinoma as oncogene. Here, we will make a review about miR-21' s target gene, biosynthesis and regulation and clinical significance in order to provide a valued data for the future study and clinical application.

Objective To explore the effects of chlamydia and mycoplasma infections on the healing of wounds after surgical operation for haemorrhoids,fistula and anoschisis.Methods Sixty-two patients with haemorrhoids,fistula and anoschisis undergoing the surgical operation during 2000.1 to 2008.10 were collected,and wounds did not heal 40 days after operation and the wound's surface infection occurred after postoperative anti-inflammatory therapy and dressing change.All patients were positive at least for laboratory Ct or Uu,and those with infections caused by other fungi,bacteria,viruses and the other systemic diseases were excluded.The correlation between the infections in 62 cases and sex,surgical types was analyzed.Results In 62 patients,there were 30 cases (48.4%) positive for both Ct and Uu,22 cases for single Ct (35.5%),and 10 cases for single Uu (16.1%),respectively.The infection rate in females was higher than in males (P<0.01).The surgical types included:surgery for 8 cases of haemorrhoids (12.9%),for 18 cases of fistula(29.0%),and for 36 cases of anoschisis(58.1%).respectively.Conclusion There is the possibility of chlamydia and mycoplasma infections in the patients with delayed healing of wounds following the surgical treatment on the anal region.Early diagnosis,early treatment,avoidance of ineffective medicines and repeatedly management of the wounds can shorten the healing period.
