Objective To determine the efficacy and safety of intravenous iron sucrose and oral iron dextran in renal anemia patients. Methods Sixty renal anemia patients were randomized into two groups:intravenous iron group(IV group, 100 mg iron sucrose twice a week) and oral iron group(oral group, 150 mg iron dextran every day). The changes in hemoglobin (Hb),hematocrit (Hct),serum ferritin (SF),and transferrin saturation (TSAT) were assessed on week 4,8, and 12 after treatment. The maintenance dosages of erythropoietin (EPO) after reaching treatment target and the adverse events were also observed. Results Hb increased after treatment in IV group [(79.87 ± 13.19) g/L to (106.11 ± 12.38) g/L] and oral group [(85.41 ± 11.49) g/L to (94.68 ± 10.06) g/L],and compared with that before treatment, there was significant difference in each group(P< 0.01 ). Also significant difference showed in Hb levels after treatment between two groups(P< 0.01 ). SF and TSAT levels were higher after treatment in IV group than those in oral group (P < 0.01 ). The adverse event was lower in IV group (0) than that in oral group (16.7%,5/30).Conclusions Oral iron dextran which has more adverse events and poor efficacy in curing anemia, can not correct anemia ideally. Meanwhile intravenous iron sucrose has positive effects on renal anemia with low adverse events, and it can be used as a long term iron supplementation in hemodialysis patients.

Purpose　To investigate the pathomorphological and immunohistochemical features of gastrointestinal stromal tumors (GIST). Methods　Light microscopy was used to study the morphologic characteristics of 77 cases of GIST. The expression of c-kit(CD117), CD34, vimentin, SMA and S-100 protein were detected in all cases with S-P immunohistochemical method. Results　GIST tended to have a higher degree of cellularity and lesser degree of cytoplasmic eosinophilia than observed in classic leiomyomas. The neoplastic cells of GIST were spindle, epithelioid or both in different proportion. Focal to prominent cytoplasmic vacuolization was often seen. The histological spectrum included interlacing fascicles, diffuse sheets, storiform and palisading pattern. The formation of cell clusters was rather special. Stromal and vascular hyalinization was common. GIST primary in the mesentery tended to have a higher potentiality of malignancy. The positivity of CD117 and CD34 were 90%, 92%, respectively. Conclusion　The characteristic histological features exist in GIST. The detection of CD117 and CD34 is helpful to differential diagnosis.

Objective　To explore the cause, diagnosis and treatment of retroperitoneal fibrosis.Methods　5 cases of retroperitoneal fibrosis were respectively treated by moving ureter into abdomen cavity, encapsulating with pediculate omenta and ilel ureter.Results　Following-up of 5 cases for 1 to 3 years, all cases had normal renal functions and hydronephrosis were much decreased.Conclusions　Intravenous urogenous(IVU),retrograde pyelography(RGP) and computed tomography (CT) are important methods to diagnose the disease. And the treatment method chosen depends on the range, location of ureterostenosis, and whether the ureter is open or not.

Laryngeal interarytenoid neurilemmomas (LIN) is a benign encapsulated tumor originating from the schwann cells lining nerve fibers. Even though LINs are extremely rare in incidence, they could present with potential threat to the airway and thus requiring prompt diagnosis and treatment. Here, we report two cases of LINs. Both patients underwent excision of the tumor via microlaryngeal endoscopic procedures and recovered well postoperatively without complications. No recurrence was observed postoperatively on routine follow-up after 14 months.

Biopsies were randomly taken from 160 patients through endoscopy. Among them 46 patients suffered from chronic superfacial gastritis, 39 patients from chronic atrophic gastritis, 39 patients from gastric ulcer, and 36 patients from gastric cancer. Ras, p16, and p53 genes were analysed with polymerase chain reaction single strand conformation polymorphism (PCR SSCP). Helicobacter pylori (HP) was examined with RUT. Result: ① the positive rates of ras and mutant p53 in gastric cancer were significantly higher than that in gastritis and gastric ulcer( P

Objective To study an effective pathway in preventing the recurrence of hepatocellular carcinoma(H.C.C) and improve the long-term curative effects.Methods 103 resectable cases of H.C.C were randomly divided into treatment group,hepatectomy plus hepatoarteria-and portal chemotherapeutics embalizations with subcutaneous pump(HACE and PVCE) group and control group(Only hepatectomy).Based on changes of ?-fetoprotein(AFP) for pre-and post operation and results of"B" ultrasound and CT,hepatic artery portography,the difference of 1,3,5-year recurrence rates and survival rates between the two groups were compared.Results ⑴The recurrence rates of treatment group and control group for 1,3,5-year were 13.5%,46.2%,67.3% and 19.6%,60.8%,86.2% respectively,there was an obviously difference (P

Objective To study the effectiveness of the complete ureterel reconstruction using bladder flap after cadaveric renal transplantaion.Methods In 13 recipients with complete necrosis of ureter after renal transplant from July 1995 to October 2003, tubelike bladder flaps were applied to ureteraplasty substitute for the necrosis ureter. Artificial pyeloureterostomy was performed and double T tubes were used as the stents. Routine drainage-tubes were placed in incisions. Results All patients were successful in ureteral reconstruction. The renal function of 10 patients was improved significantly 4 weeks postoperation. Nephrectomy was performed in one patient because of severe circumrenal infection 7 days after operation. One-year survival rate of recipients and allografts was ~100 % (13/13) and ~92.3 % (10/13) respectively. Urine reflow occurred in 2 patients during a follow-up of 12 months. Conclusion The use of bladder flap for ureteral reconstruction is an effective technique for total autograft ureteral necrosis.

Objective To study the effects and safety of levocarnitine and shuxuetong in treatment of the patients with chronic renal failure.Methods 94 patients with chronic renal failure were selected as research object,and they were randomly divided into group A(levocarnitine and shuxuetong group) 47 cases and group B(shuxuetong group) 47 cases.Group A were treated with levocarnitine oral solution and shuxuetong,and group B were treated with shuxuetong,then the percentage of effectiveness,incidence of adverse reactions of group A and group B and serum BUN,Scr,Hcy were analyzed.Results The percentage of effectiveness of group A was higher than that of group B,but the incidence of adverse reactions of the two groups had no difference,and the serum BUN,Scr,Hcy of group A and group B before the treatment had no differences(P＞0.05),those of group A and group B after treatment were compared there were significant differences(all P＜0.05).Conclusion The effects of levocarnitine oral solution and shuxuetong in treatment of patients with chronic renal failure were better.

Objective To study the influence of different dialysis frequence on infection and prognosis of maintenance hemedialysis patients. Methods Fifty-three maintenance hemodialysis patients with chronic kidney disease were divided into 3 groups. Groups A, B, C dialysed thrice per week (19 cases),twice per week (15 cases) and thrice per two weeks (19 cases), respectively. All the patients were dialysed for 1 year. The rate of infection, death number and death reason were recorded. Results All the cases were infected 62 times (17 times in group A, 18 times in group B and 27 times in group C). Pulmonary infection,blood vessels infection, urinary tract infection and digestive tract infection happened 35 times(56.45% ), 14 times (22.58%), 8 times (12.90%) and 5 times (8.06%) respectively. Eight cases died in three groups,and the total death rate was 15.09%, with 1 case in group A,1 case in group B and 6 cases in group C.There was significant difference in prognosis among three groups (χ2 =6.293,P <0.05). Conclusions Patients who dialysis less than twice per week have higher rate of infection and death. Dialysis program should be adjusted and dialysis frequence should be increased.

The incidence of toxic keratopatby is increasing yearly.Due to the shortage of specific clinical manifestations,the diagnosis and treatment of the disease are relatively difficult,hence toxic keratopathy has received extensive attention of the domestic and abroad scholars.In recent years,with the development of ophthalmic examination technology and progress of instruments,its mechanism,diagnosis and treatment have been newly cognized.These three aspects will be reviewed in this article.
