ABSTRACT
OBJECTIVE:To establish a method for the determination of the concentration of cefoperazone sodium in cefoperazone sodium / sulbactam sodium in bile by HPLC.METHODS:The bile specimen was collected from the gallbladder of patients during laparoscopic cholecystectomy and the concentration of cefoperazone sodium was determined by HPLC.The separation of cefoperazone sodium was performed on YWG C18 with column temperature at 35℃.The mobile phase consisted of methanol-water-glacial acetic acid(25.5∶74.5∶0.45) with flow rate at 1.0mL?min-1 and UV detection wavelength at 254nm.RESULTS:The linear range of ceforazone sodium in human bile was 1.25～62.5?g?mL-1(r=0.999 1),and its average recovery was 95.14%(RSD=3.42%).CONCLUSION:The above method is simple and reliable,and it can provide bases for clinical rational use of drugs.
ABSTRACT
It is inevitably that any medical laboratory instrument may have trouble during its operation no matter how advanced it is.The only difference is the failure rate of each medical laboratory instrument.So in order to ensure these instruments work normally,it is very important to maintain them correctly.This paper gives an introduction of characteristics and maintenance requirements about medical laboratory instruments.
ABSTRACT
Objective To study the bladder function after internal iliac artery chemotherapy for bladder carcinoma. Methods Internal iliac artery chemotherapy was undertaken for 38 cases of bladder carcinoma comprehensively treated by TURBt,partial cystectomy or paliative TURBt.12 were T 1 carcinoma,14 T 2 and 12 T 3. Results The urinary bladder has been preserved in 33 patients.Of the 12 T 1 carcinoma,repeated recurrence occurred in 4.TURBt was undertaken on each occasion whereas total cystectomy was finally carried out in 2 of them.The bladder has been preserved in 10 of 14 and the 10 are still alive;of 14 T 2 (regional infiltrating carcinoma)patients,1 died of metastasis 2 years after surgery and another complicated by renal failure due to chemotherapy and has been on hemodialysis.The bladder has been preserved in 13 of the 14 and the 13 patients are still alive;of the 12 T 3 patients,8 were high risk patients,2 of them died of the cancer 2～3 years after the operation.Tumors vanished in 3 patients with negative multiple randomized biopsy.Tumors became smaller in 7 and partial cystectomy was performed for 3 of them.Of another 4 with shrunken tumors,hematuria has been controlled,the bladder capacity increased and the general condition of the patients improved.The bladder has been preserved in 10 of the 12.The mean survival time has been 58 months. Conclusions Internal iliac artery chemotherapy is effective and useful for some bladder cancer with the bladder function preserved.
ABSTRACT
Objective To study the pathogenetic characteristics of tertiary hyperparathyroidism. Methods The diagnosis and treatment of a male patient with tertiary hyperparathyroidism were reviwed. Results The patient who had had chronic renal failure underwent excision of the adenoma of parathyroid gland 5 year ago.After that,the total parathyroidectomy and autografting were performed because of his recurrent hyperparathyroidism.The patient began hemodialysis therapy 3 years ago and then underwent allogeneic kidney transplantation 2 years ago.Two months after the operation,symptomatic hyperparathyroidism relapsed.The autonomic parathyroid grafts were removed three times (one part of the grafts resected each time) with relapse occurring three times.Later the hyperparathyroidism was cured by itself after the patient was mentally irritated. Conclusions Tertiary hyperparathyroidism may have already developed before kidney transplantation.
ABSTRACT
Objective To study the diagnosis and treatment of ectopic testes. Methods 7 cases of ectopic testes were reviewed and studied. Results 5 cases of ectopic testes were diagnosed and located by physical examination and/or type B ultrasonography before operations whereas the ectopic testes was atrophic in the other two.All the ectopic testes were found successfully during surgical exploration.Orchidopexy was performed for 5 patients,and orchiectomy for the other 2 because of marked atrophy.Postoperative follow up has been 2 months to 8 years.All the patients have normal growth.In the 5 cases with reposited testes no displacement,atrophy or malignant change has been noted. Conclusions The diagnosis of ectopic testes should be mainly depended on physical examination and type B ultrasonography.Surgical exploration should be carried out through the inguinal canal and via the pathway of spermatic cord.
