OBJECTIVE:To observe therapeutic efficacies and safety of diltiazem combined with ciclosporine in the treatment of nephrotic syndrome complicated with acute renal injury. METHODS:A total of 66 patients with nephrotic syndrome and cute kid-ney injury were randomly divided into control group(30 cases)and observation group(36 cases). Control group was given routine treatment;observation group was additionally given Diltiazem hydrochloride tablet 5 mg orally,twice a day,and Ciclosporin soft capsules 1.5 mg/(kg·d)orally,twice a day. Treatment course of 2 groups lasted for 20 d. Clinical efficacies of 2 groups were ob-served. The serum creatinine and kidney injury molecule 1(KIM-1),24 h urine volume,24 h urine protein levels,AKI classifica-tion,follow-up and recurrence were observed before and after treatment as well as the occurrence of ADR. RESULTS:The remis-sion rate of observation group was significantly higher than that of control group,and recurrence rate was significantly lower than control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the serum creatinine levels,KIM-1,24 h urine pratein,24 h urine and AKI classification between 2 groups (P>0.05). After 2 weeks and 1 month of treatment of observatiom groups,and after 1 month of treatment of control group,serum creatinine levels,KIM-1 and 24 h urine protein of observation group were significantly lower than before treatment,and the observation group was significantly lower than the control group;24 h urine and the ratio of gradeⅠby AKI classification were significantly more than before treatment,and the observation group was significantly more than the control group,with statistical significance(P<0.05). Follow-up rate in 2 groups were 100%,and there was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,diltiazem combined with ciclosporin shows significant therapeutic efficacy in the treatment of nephrotic syn-drome and acute renal injury with good safety.

Objective:To investigate the culture technique and secretory function of parathyroid cells in rats in order to establish experimental basis of parathyroid cell transplantation.Methods:After parathyroid glands were digested by collagenase and trypsin,isolated parathyroid cells were cultured.The cells cultured for 5 days were observed by transmission electron microscopy.Parathyroid hormone obtained from the cell culture fluid on day 1,3,5 and 7 was measured respectively.Results:Parathyroid cells cultured for 5 days had abundant rough surfaced endoplasmic reticula、Golgi bodies、stab mitochondria and secretory granules.Cultured parathyroid cells could secrete parathyroid hormone normally,especially on the 5th day.Conclusion:Parathyroid cells cultured for 5 days still possess original morphologic structure and have maximum secreting function,so it is an optimal donor for transplantation.

Buthionine salfoximine (BSO) is a chemotherapeutic sensitizor under clinical trial. BSO can reverse multidrug resistance in vitro and in vivo. The author reviewed the mechanism, pharmacodynamics, pharmacokinetics and the progress in clinical research of BSO. BSO is a selective inhibitor of 7-glutamylcysteine synthetase, the rate-limiting enzyme in gluthionine synthesis. Depletion of intracellular gluthionine by BSO can reverse tumor resistance to chemotherapeutic a-gents such as platinating and alkylating agents. In tumor-bearing animals BSO enhanced the therapeutic index of chemotherapeutic agents. Animals treated with BSO had a longer life span. Pharmacokinetics of BSO was a two-compartment manner in mice, dogs and huamn beings. The efficacy of BSO in cancer patients is being investigated in clinical trial.
