BACKGROUND: Acute rejection is a main complication and the major risk factors of chronic rejection and chronic graft dysfunction (CGD) after renal transplantation. Therefore, it is significant to investigate the effect of hydrogen ion excretion of renal tubule on the early diagnosis of the dysfunction of graft in renal transplantation patients.OBJECTIVE: To explore the effect of the hydrogen ion excretion of renal tubule on the diagnosis and efficacy of acute and chronic rejection of graft after renal transplantation.DESIGN: Case-controlled observation.SETTING: Department of Urinary Surgery, General Hospital of Jinan Military Area Command of Chinese PLA.PARTICIPANTS: A total of 26 patients after successive renal transplantation were enrolled at Department of Urinary Surgery, General Hospital of Jinan Military Area Command of Chinese PLA from May 2000 to June 2005. The age of all patients ranged from 21-58 years with an average of 35 years, including 16 males and 10 females. Recipients' primary diseases were chronic glomerulonephrltis (CGN) and chronic renal function failure (CRF). One patient was in the 2nd transplantation. All patients received cadaveric renal transplantation. Donors and recipients had the same blood type and negative of lymphocytotoxicity test. All patients singed the informed consent.METHODS: According to clinical symptoms and bloodstream tested by color Doppler ultrasound, 16 patients without rejection were considered as stabilization group and 10 patients with rejection as rejection group. The rejection group was divided into prerejection, rejection and recovery phases. Medistream urine was collected with clean chemical glass bottle in the morning before operation and at week 1 after operation, once a week for successively 10 weeks. Urine titratable acid, NH+4 and net acidity levels were measured to evaluate hydrogen ion excretion of renal tubule.MAIN OUTCOME MEASURES: Urine titratable acid (TA), NH+4 and net acid excretion capacity (NAC) levels of patients in the two groups.RESULTS: Totally 26 patients were involved in the result analysis. Hydrogen ion excretion of renal tubule examination showed that the hydrogen ion excretion was intended to normal in rejection prophase patients. The hydrogen ion excretion of renal tubule was significantly decreased in the rejection phase patients, compared with those in the rejection prophase patients and patients of stabilization group (P < 0.01 ). The hydrogen ion excretion of renal tubule was recovered rapidly in the most acute rejective patients after treatment. The recovery of hydrogen ion excretion of renal tubule was various. The recovery time of most cases ranged from 1-10 weeks with an average of about 6 weeks, 2 cases did not recover in 10 weeks and 3 cases of 4 severe rejection cases had slow recovery after treatment.CONCLUSION : Hydrogen ion excretion of renal tubule can bridge the gap of bad reflection of renal tubule function from serum creatinine (Scr) and can diagnose the acute rejection after renal transplantation in continuous observation, and especially can be as a valuable index to assess curative effect and prognosis of rejection treatment.

Objective To investigate the clinical efficacy of Wumei Wan (Fructus Mume Pills) for diabetic gastroparesis with the syndrome of cold-heat mixture. Methods Sixty-eight diabetic gastroparesis patients with the syndrome of cold-heat mixture were evenly randomized into treatment group and control group. On the basis of treatment for controlling the blood glucose level, the treatment group was given oral use of Wumei Wan and the control group was given oral use of Cisapride. After treatment for one month, the therapeutic effect of both groups was evaluated, and the changes of gastrointestinal symptoms, gastric emptying, 2-hour postprandial glucose(2hPG), glycosylated hemoglobin(HbA1c), and fasting plasma glucose(FPG) in both groups were also observed. Results (1)The total effective rate of the treatment group was 88.24%, and that of the control group was 67.65%, the difference being significant(P<0.05). (2 ) After treatment , the scores of gastrointestinal symptoms of nausea and vomiting, gastric fullness, anorexia, belching and acid regurgitation, abdominal and gastric pain, diarrhea, and constipation in the treatment group were markedly improved(P<0.05 or P<0 . 01 compared with those before treatment ). In the control group, symptom relief was shown in nausea and vomiting, anorexia, and diarrhea(P<0.05). The treatment group had better effect on relieving nausea and vomiting, abdominal and gastric pain, diarrhea, and constipation than the control group(P<0.05 or P<0.01). (3)After treatment, 2hPG, FPG and HbA1c levels were obviously decreased in both groups(P<0.05 compared with those before treatment) , and the decrease in the treatment group was superior to that in the control group (P<0.05). (4)After treatment, half gastric emptying time, full gastric emptying time, and the contraction of gastric antrum were improved in both groups(P<0.05), and the improvement of gastric emptying in the treatment group was superior to that in the cont rol group(P<0.05). Conclusion Wumei Wan has better effect for the treatment of diabetic gastroparesis than western medicine Cisapride.
