OBJECTIVETo observe the effects of acupuncture-moxibustion on chronic allograft nephropathy (CAN) and explore the methods of acupoint selection along meridian for transplanted-kidney-related diseases.
METHODSA total of 180 patients of CAN were randomized into a syndrome differentiation group, a spleen-meridian group, a kidney-meridian group and a control group, 45 cases in each one. A total of 33 cases dropped out before the end of the study, including 8 cases in the syndrome differentiation group, 12 cases in the spleen-meridian group, 13 cases in the kidney-meridian group and no case in the control group. Patients in the control group were treated with conventional western medicine; based on this, patients in other three groups were treated with acupuncture-moxibustion. In the syndrome differentiation group, Qihai (CV 6), Hegu (LI 4), Guanyuan (CV 4), Feishu (BL 13), Shenshu (BL 23), etc. were selected for qi deficiency of lung and kidney; Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), etc. were selected for deficiency of qi and yin; Ganshu (BL 18), Shenshu (BL 23), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), Ququan (LR 8), etc. were selected for yin deficiency of liver and kidney; Zhongji (CV 3), Guanyuan (CV 4), Mingmen (GV 4), Guanyuanshu (BL 26), etc. were selected for yang deficiency of spleen and kidney. In addition, Sanyinjiao (SP 6), Diji (SP 8), Yinlingquan (SP 9), Xuehai (SP 10), etc. were added in the spleen-meridian group; Taixi (KI 3), Zhaohai (KI 6), Fuliu (KI 7), Ciliao (BL 32), etc: were added in the kidney-meridian group. Serum creatinine (Scr), creatinine clearance (Ccr) and 24-hour urinary protein before and after the treatment were com- pared among the four groups.
RESULTSAfter treatment, 24-hour urinary protein in the acupuncture-moxibustion groups and control group were all reduced (all P < 0.05); compared before treatment, the Scr in the spleen-meridian group was significantly reduced (P < 0.05); the difference of Ccr before and after treatment was insignificant in all the groups (all P > 0.05). Compared with the control group, 24-hour urinary protein in spleen-meridian group could relieve or recover the damage of transplant kidney induced by CAN. A new interlink may be established between the transplanted kidneys and the spleen meridians, indicating that transplanted kidney-related diseases can be treated by selecting acupoints of spleen meridian.

Objective To probe into the clinical features, ways of diagnosis and treatment measures of concurrent paratyphoid fever A after renal transplantation. Methods The 5 patients were all town or village people under the county level. After the operation, the immunosuppressive scheme of ciclosporin A (or Tacrolimus) + mycophenolate mofetil (MMF) + prednisone acetate was adopted. One case was caused by catching cold and the rest 4 had no any distinct inducement. Five patients fell ill respectively at the 5th, 7th, 7th, 9th and 14th month after the operation. On the admission, the 5 patients suffered from gastrointestinal symptoms such as vomiting and diarrhea to varying degrees; 3 from toxic symptoms such as fever, intolerance of cold, hypodynamia and headache; 3 from symptoms of the respiratory system such as stuffy nose and congestion of throat; 1 from elevation of blood pressure; 1 from relative slow pulse. In 3 patients with decrease of urine volume, 1 suffered from gross hematuria, swelling of transplanted area of the kidney, pain on pressure and rise of blood pressure. Only 1 patient's paratyphoid fever A antibody in the Widal's test gastroenteritis or untoward reaction of MMF and the curative effect was bad. After definite diagnoses,the combined treatment of the third-generation cephalosporin and FQNS were given to all of them.After treatment for 7-10 days, the symptoms in all patients all disappeared. During the treatment, 1 patient was diagnosed as acute rejection and given the methylprednisolone shock for 3 days. After that, the patient's graft function was improved; 3 patients suffered from relatively great fluctuation of blood concentration of immunosuppressive agent and toxic symptoms such as decrease of the graft function, etc. After adjustment of dosage, their indicators of renal function became normal. Conclusion Early symptoms and accessory examinations of paratyphoid fever A after renal transplantation lack specificities. Diagnosis of paratyphoid fever A after renal transplantation mainly depends on blood culture. Drugs of first choice include FQNS and the third-generation cephalosporin. During the treatment, the doctor should closely monitor blood concentration of the immunosuppressive agent.

Objective To provide references for enriching and innovating patterns of TCM syndrome differentiation by exploring the relationship between pathological changes and TCM syndrome differentiation of delayed graft function (DGF) after renal transplantation. Methods Totally 57 patients with DGF after renal transplantation who were diagnosed by pathological biopsy were also diagnosed by TCM doctors to obtain TCM syndromes. And the pathological diagnoses were compared with the distribution of TCM syndromes to discuss the relationship between them. Results All the patients were classified into four TCM syndromes:spleen-kidney qi deficiency, liver-kidney yin deficiency, qi-stagnation and blood stasis, and deficiency of both qi and yin. The results of pathological biopsy were as follows:acute tubular necrosis, calcineurin inhibitor toxicity and acute rejection. Quantitative corresponding relation was found between the pathological diagnoses and the TCM syndromes. Conclusion There are inner links between pathological diagnosis and TCM syndromes of DGF, which can be references for diagnosis and treatment of TCM syndrome differentiation.

BACKGROUND: Security of organ donor attracts more attention, because donor complication and transplantation failure always occur following renal transplantation. Therefore, living-related kidney transplantation should be paid much attention in order to make sure life and quality of life. OBJECTIVE: To investigate the safety of living-related kidney transplantation. METHODS: A total of 38 cases of living relative donor kidney transplantation were retrospectively analyzed. Before transplantation, identify of patients should be determined, and all patients provided the informed consent. The general data of patients were sufficiently dialyzed before transplantation to improve the body status. TacroUmus or mixture of cyclosporine A, mycophenolate, and adrenal cortex hormone were administrated following transplantation to observe renal function, complication incidence, and acute rejection reaction. RESULTS AND CONCLUSION: Due to short waiting time, low price, and long-term survival rate, living-relative donor kidney transplantation has low risk factor, s for donor. However, the safety still needs to be sufficiently evaluated for donors and recipients.
