Journal of Third Military Medical University 2002;0(12):-
Objective To analyze the biochemical effect of cryosugery on residual bronchial tissue and the adjacent organs in dogs. Methods Bronchial stumps of 18 dogs after lobectomy and the adjacent tissues and organs(including 4 samples of esophagi, 3 diaphragms, 3 stomachs, 2 livers, 7 tracheae and 3 superior saphenous vein sinuses) of 22 dogs after thoracectomy were frozen. The observation from 1~212 d was conducted after surgery. Results Cryonecrosis and fibrosis were found in all 18 samples of the frozen bronchial stumps, but no fistula of bronchial stump was found. Three cryodamaged esophagi in 4 dogs developed fine sheet of fibrous membrane like scars in the situs of cryosurgery. Perforation was found in 2 dogs, one in the esophagus, another in stomach. No perforation was found in dogs with diaphragm cryosurgery. Cartilaginous ring disappeared in 7 dogs by cryosurgery of the trachea and a membrane like scar developed in the inner wall of trachea. There were yellow scars on the liver after cryosurgery. Conclusion Exfoliation of the necrotic tissues is slow due to the slowly developed cryonecrosis and good tolerance to cryosurgery of the fibrotic tissues. The original construction disappears but fibrosis develops. At the edge of cryo necrotic area, proliferation of capillary can be found.

Objective To evaluate the prevalence,management and risk factors of post transplantation anemia (PTA) in a group of Chinese kidney transplant recipients after a long-term follow-up. Methods The clinical data of 154 adult kidney transplant recipients,who were followed up for at least 5 years,were retrospectively studied,including yearly hemoglobin (Hb) level,the prevalence and treatment of anemia,state of renal function,use of immunosuppressive agents and other medications. Patients were divided as anemic and non-anemic groups,and comparison of clinical data was carried out between the groups. The incidence of anemia was calculated and management of anemia was recorded. Monofactorial correlation analysis was used to determine the factors associated with Hb level,and multi-variation logistic regression was used to identify the factors related to the onset of anemia at 1 and 5 years post-transplant. Results The annual incidence of PTA at the current year of and 1 to 5 years after transplantation was 45.5%,10.7%,9.6%,14.8%,13.5% and 19.5%,respectively. About 38.3% of the patients suffered from anemia at least once during the 5 years of follow-up period,and 42% of these patients developed anemia recurrently. Correlation analyses indicated that Hb levels were associated with graft function (P0.05). Logistic regression model showed that serum creatinine and blood urea nitrogen levels were associated with the diagnosis of anemia in the 1st year after transplantation (P

Objective To assess the accuracy of cerebral oxygenation measured by near-infrared spectroscopy (NIRS) in predicting ischemic cerebral injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB). Methods Seventeen patients undergoing cardiac valve replacement under CPB were enrolled in this study. During operation, NIRS was used to measure regional oxygen saturation (rScO2),tissue hemoglobin index ( THI ), changes in concentrations of oxyhemoglobin (△ O2 Hb ), deoxyhemoglobin (△ HHb) and total hemoglobin (△ cHb) of the frontal lobes. The parameters mentioned above and patients whose minimal rScO2 decreased to less than 50% were recorded after entering the operation room, immediately after tracheal intubation, aortic cannulation and superior and inferior vena cava cannula, at the beginning of CPB, at the lowest temperature during CPB, after rewarming to 36.5 ℃, immediately after termination of CPB, and at 1 h after termination of CPB. Blood samples were taken from right internal jugular vein immediately before anesthesia induction, before rewarming, after rewarming to 36.5 C, and at 1, 5 and 20 h after termination of CPB to detect plasma concentrations of S100 protein and neuron-specific enolase (NSE) by ELISA. The cognitive function of patients was assessed 1 day before surgery and 8 days after surgery, and postoperative cognitive dysfunction (POCD) was recorded. Results Nine patients presented with minimal rScO2 less than 50%. Among them,7 patients developed POCD. The plasma concentrations of S100 protein and NSE were significantly higher at 1 and 5 h after termination of CPB in patients whose minimal rScO2 decreased to ≤ 50% than in those whose rScO2 >50% .Conclusion Cerebral oxygenation measured by NIRS can accurately predict cerebral ischemic injury in patients undergoing cardiac valve replacement under CPB.

Objective To investigate the role of retroperitoneal lymph node dissection (RPLND) in the treatment of testicular cancer. Methods The clinical data of 39 cases (age range,20-58 years;median age,29 years) of germ cell tumor who underwent RPLND were retrospectively analyzed.Of the 39 cases,17 had the tumors on the left side and 22,on the right.One case was of seminoma,and the other 38 were of non-seminomatous germ cell tumor (NSGCT).According to the clinical examinations and radiology, 20 cases were of stage Ⅰ,15 of stage Ⅱ,and the rest 4 could not be staged. Results Of the 39 cases,10 with stage I tumors underwent nerve-sparing modified RPLND and the other 29 underwent bilateral RPLND.No metastasis was found in the dissected tissues in 22 cases,while metastasis,in 17 (including 4 of clinical stage I).All the patients with pathological metastases or elevation of blood tumor markers received postoperative chemotherapy.Follow-up was carried out for 1-149 months.The disease-free survival rate was 97.4%(38/39).Of the 10 cases receiving modified RPLND,8 regained their ejaculation function. Conclusions The probability of presence of the non-seminomatous components must be considered in the diagnosis and follow-up of seminoma cases,and the RPLND should be done if necessary.Nerve-sparing modified RPLND should be performed for clinical stage Ⅰ patients;while postoperative chemotherapy should be chosen for pathological stage Ⅱ patients.

Objective To compare the effect of ropivacaine mesylate with ropivacaine HC1 for patient-controlled epidural analgesia ( PCEA) after transabdominal hysterectomy. Methods Forty-four ASA 1 or D patients aged 18-65 yrs weighing 45-80 kg undergoing elective abdominal hysterectomy performed under epidural anesthesia with either 0.75% ropivacaine HO (control group, n = 22) or 0.894% ropivacaine mesylate (study group, n= 22) . An epidural catheter was placed at L2,3 and advanced 3 cm into the epidural space. After operation PCEA was performed with 0.2% ropivacaine HCl ( control group) or 0.237 % ropivacaine mesylate (study group) respectively. Postoperative pain was assessed using VAS (0-10, 0 = no pain, 10 = worst pain) . Motor blockade was assessed using the Bromage scoring system. The patients' satisfaction level and adverse events were also recorded. Results There were no significant differences in VAS scores, motor blockade and incidence of adverse events between the two groups. The number of effective pressing in study group was significantly less than that in control group. Starting from 4h after operation the drug consumption in study group was significantly less than that in control group. Conclusion 0.237 % ropivacaine mesylate can be used for PCEA after transabdominal hysterectomy as safely as 0.2% ropivacaine HCl.
