Objective To investigate the efficacy of minimally invasive percutaneous nephrolithotomy(MPCNL) for impacted upper ureteric calculi.Methods Retro-urethral catheterization was conducted in the diseased ureter under cyctoscope.After a channel from the skin surface into the middle calyx was established under the guidance of X-ray or B ultrasonography,pneumatic lithotripsy was conducted to break up stones under ureteroscopy.Results The success rate of pneumatic lithotripsy was 100%.The rate of postoperative macroscopic hematuria was 55.1%(27/49).The symptom lasted one to three days in 26 cases,and 1 case had apparent hematuria with blood clot flowing out from nephrostomy tube,which lasted 8 days.10.2%(5/49) of cases was complicated with postoperative pyrexia.The stone-free rate in one week and one month postoperatively was 93.9%(46/49) 98.0%(48/49),respectively.Follow-up observations in 49 cases for 1-12 months(mean,5 months) showed no major complications.Conclusions MPCNL for impacted upper ureteral calculi has the advantages of simple performance,less complications and satisfactory efficacy.

Objective To detect the changes of renal hemodynamics, radionuclide renal dynamic imagings were performed in patients with type 2 diabetes millitus (DM) in different stage. Methods Fifty seven patients with type 2 DM were divided into 3 groups according to the value of urinary albumin excretion rate (UAER). (1)GroupDM1:UAER200 ?g/min, 20 cases. 99m Tc DTPA and 99m Tc EC renal dynamic imagings were performed in the type 2 DM patients of 3 groups and 20 normal controls (NC). Glomerular filtration rate (GFR), effective renal plasma flow (ERPF) and renogramweregainedsimultaneously.Results GFR and ERPF were significantly increased in group DM1 than those in NC (P

0.05), but there were significant differences after the operation (P

Objective:To explore the effect of comprehensive intervention program based on the concept of fast track surgery in early enteral nutrition tolerance and rehabilitation in patients with esopha geal cancer.Methods:93 selected patients were divided into the intervention group and the conventional control group according to the admission time.Patients in intervention group were treated with comprehensive intervention,and control group were given routine nursing care.Enteral nutrition intolerance incidence,the first time of bowel sounds,the first time exhaust and defecation and complications were compared between the two groups.Results:36 patients from 47 patients (76.60％) in the intervention group could tolerate the early feeding,while 24 patients from 46 patients (52.17％) in the control group could tolerate.There was significant difference between two groups (P ＜ 0.05).The first time of exhaust,bowel sounds and defecation,and the hospitalization time of patients in the intervention group were better than that in the conventional control group (P ＜ 0.01).Incidence rate of incision infection,pulmonary infection and intestinal obstruction in patients of the comprehensive intervention group was lower than that in the control group (P ＜ 0.05).Conclusion:Compared with the traditional treatment,the comprehensive intervention can effectively reduce the enteral nutrition intolerance incidence,promote the recovery,reduce hospitalization time and the incidence of postoperative complications,and improve the life quality of patients after surgery.

Objective To investigate the existence of epithelial-mesenchymal transition(EMT)and its relation to the expression of HBx protein in hepatocellular carcinoma(HCC).Methods The expression of HBx protein,E-cadherin,β-catenin,N-cadherin and fibronectin were detected by immumnohistochemistry technique in 76 cases of HCC.Results Among 76 HCC samples,the loss of expressions of E-cadherin and β-catenin were 34%(26/76)and 20%(15/76),respectively.The positive expressions of HBx protein,N-cadherin and frbronectin were observed in 68%(52/76),55%(42/76),46%(35/76)of HCC samples,respectively.The loss of expression of E-cadherin significantly correlated with the positive expression of N-cadherin and HBx protein (P＜0.01).The positive expression of N-cadherin and fibronectin significantly correlated with the loss of expression of β-catenin and the positive expression of HBx protein(P＜0.05).Conclusions EMT exists in hepatocellular carcinoma,and the expression of HBx is significantly associated with EMT.

Through study on the correlation between atractylodis lactones ingredient content and climatic factors, we research regionalization from climatic of five main producing provinces of the country, in order to provide a scientific basis for atractylodis' conscious cultivation. By sampling from 40 origins which from five main producing provinces of the country, we use SPSS to analysis variation of atractylodis lactones ingredient content in different conditions of climatic factors and the effect of each factors. Then according to the relationship between atractylodis lactones ingredient content and climatic factors, we use ArcGIS to conduct ecological suitability regionalization based on climatic factors. The most suitable climatic condition for cultivation of atractylodis: the wettest month precipitation 220-230 mm, the warmest average temperature 25 degrees C, the average temperature of driest season 10 degrees C.

Objective To determine the concentrations of amphotericin B in serum and cerebrospinal fluid from patients with AIDS-associated cryptococcal meningitis.Methods Ten patients with AIDS-associated cryptococcal meningitis were enrolled in the study.Blood samples were collected before drug administrated at the 7th.14th and 21 th day after maintenance dose achieved.Cerebrospinal fluid samples were collected from lumbar puncture or taken before intrathecal drug administration at least one week after maintenance dose achieved.The concentrations of amphoteriein B in blood and cerebrospinal fluid samples were determined using RP-HPLC.Results When maintenance doses varied from 25 to 40 mg/d,the blood steady-state trough concentration range of amphotericin B was 1.34-2.27 ms/L,and that of cerebrospinal fluid was 44.0-9 1.7μg/L.Conclusions The concentrations of amphotericin B in the cerebrospinal fluid would be lower than the desired concentration if amphotericin B administrated only through intravenous or integrated with irregular intrathecal administration.It suggests that higher dosage of intravenous injection and regular intrathecal administration should be applied to achieve the desired concentration.
