Objective To observe the effect of modified Qinghao Biejia Decoction ( QBD) on Th17 cells and renal pathology of MRL/lpr mice with spontaneous systemic lupus erythematosus. Methods Thirty-two female MRL/lpr mice aged 8 to 10 weeks were divided into 4 groups: model group, Chinese medicine group, prednisone group, and combination group, 8 mice in each group. Eight female C57BL/6 mice aged 8 to 10 weeks served as normal control. Mice in Chinese medicine group were given concentrated solution of modified QBD (19.25 g·kg-1·d-1), mice in the prednisone group were given water solution of prednisone acetate (8.75 mg·kg-1·d-1) , mice in the combination group were given the above two kinds of medicine, and mice in the model group and normal control group were given physiological saline. After medication for 7 weeks, spleens and kidneys in all of the groups were taken out for the experiment. Th17 cells in splenic mononuclear cell suspension were detected by flow cytometry, the pathological changes of renal tissue were observed under light microscope, and activity index (AI) of renal tissue in lupus nephritis mice was scored. Results The proportion of Th17 cells in the model group was significantly higher than that of normal control group ( P<0.05) . The proportion of Th17 cells in Chinese medicine group and combination group was lower than that of the model group ( P<0.05) , and prednisone group had higher proportion of Th17 cells than Chinese medicine group ( P<0.05) . Compared with the model group, pathological changes of renal tissue were relieved, and AI scores were decreased in Chinese medicine group, the prednisone group and the combination group ( P<0.05) . Except for the normal control group , AI scores in all groups were positively correlated with the proportion of Th17 cells ( r=0.77, P<0.01) . Conclusion Modified QBD can inhibit the expression of Th17 cells and improve the pathological changes of MRL/lpr mice with lupus nephritis.

OBJECTIVETo investigate the effect of nutrition protection on oxidation damage of the submarine men.

METHODS50 submarine men were randomly divided into test group and control group, 25 persons each. The test group member took VitB2 5 mg, VitC 200 mg, GPC capsule 50 mg, once every other day and VitA capsules 25 000 units for every week during the sea-voyage. The total anti-oxidative capacity (T-AOC), superoxide dismutase (SOD), malondialdehyde (MDA), the proliferation of peripheral-blood lymphocyte (PPL), the hemolytic degree of RBC and IFN-gamma were detected.

RESULTSBefore sea voyage, the difference in the T-AOC and SOD and PPL and IFN-gamma and the MDA content and the hemolytic degree of RBC between the test group and the control group were not significant (P>0.05). After sea voyage, the T-AOC and SOD and PPL and IFN-gamma in the test group [(24.08 +/- 0.10) U/ml, (44.85 +/- 0.96) U/ml, (0.29 +/- 0.05) (with H2O2), (0.34 +/- 0.04) (without H2O2) and (34.21 +/- 3.52) pg/ml] were higher than the control group [(21.06 +/- 1.10) U/ml, (42.80 +/- 1.46) nu/ml, (0.23 +/- 0.01) (with H2O2), (0.34 +/- 0.04) (without H2O2) and (31.89 +/- 3.52) pg/ml]. The MDA content and the hemolytic degree of RBC [(2.15 +/- 0.28) nmol/ml and (20.96% +/- 0.10%)] were lower than the control group [(2.44 +/- 0.32) nmol/ml and (23.12% +/- 0.77%)]. The difference was significant (P<0.05).

CONCLUSIONTo add antioxidant nutrients can improve the submarine men's antioxidant capacity.

Objective To analyze the difference in computed tomography (CT) imaging findings between pulmonary alveolar pneumoconiosis Methods proteinosis (PAP) and occupational pneumoconiosis (hereinafter referred to as ). A total of 44 patients with PAP (PAP group) and 44 patients with pneumoconiosis (pneumoconiosis group) were selected as study subjects using Results convenient sampling method. The CT images of these two groups were comparatively analyzed. The detection rates of - - pulmonary CT pattern changes such as map like performance, ground glass opacity, paving stone sign and sphenoid wing like vs vs changes of pulmonary hilum in the PAP group were higher than those in the pneumoconiosis group (77.3% 0.0%, 75.0% vs vs P 2.3%, 56.8% 0.0%, 18.2% 0.0%, all <0.01); the detection rates of lymphadenopathy and calcification of pulmonary hilum, small pulmonary nodules, emphysema and interlobular septal thickening were lower in the PAP group than those in the vs vs vs vs P Conclusion pneumoconiosis group (34.1% 100.0%, 4.5% 100.0%, 2.3% 45.4%, 0.0% 22.7%, all <0.01). Paving - stone sign and map like performance were most commonly found in the CT imaging of patients with PAP, and it is uncommon in pneumoconiosis. These changes could be used as the CT differential diagnosis of the two diseases.

OBJECTIVETo study the growth rules, the output and the influence factors of cultivated Phyllanthus urinaria, and provide basis for standardized cultivation.

METHODOrthogonally designed field experiments with three factors and three levels, comparing the characters of cultivated plants and the wild ones of P. urinaria.

RESULT AND CONCLUSIONUnder the manual planter condition, the characters, such as branching number, single dry weight, single output etc, enhanced enormously, and the increase of single output reaches 3.27 times. The sowing time was the most sensitive factor, which affected the single character and the yield per unit of area, whereas the different levels of sowing thickness and fertilizer also remarkably influenced the output. When the seeds were sowed at the mid-April earlier period, drilling with the 20 cm row spacing, they started to emerge about 1 week later, the growth flush period was from June to August, the growth slowed down in September, and the output per hectare could reach to 5.750 kilograms at harvest in late October.

OBJECTIVETo investigate the effect of compound Danshen Droplet-pill (DS) combined with trimetazidine (TMZ) in treating senile unstable angina pectoris (SUAP).

METHODSOne hundred and twenty patients with SUAP were eaually and randomly divided into 2 groups, the treated group and the control group. Changes of angina, occurrence of arrhythmia, myocardial infarction and sudden death, myocardial ischemia in ECG and partial indexes of heart function were observed.

RESULTSThe total effective rate in the treated group was 78.3%, while that in the control group was 53.3%, comparison of the two groups showed significant difference (P < 0.05). The incidence rate of arrhythmia in the two groups was 18.2% and 30.0% respectively and that of acute myocardial infarction and sudden death was 0 and 5.0% respectively, also showed significant difference between them (P < 0.05). Condition of myocardial ischemia revealed in ECG and partial indexes of heart function in the treated group were all improved to certain extent. Conclusion DS combined with TMZ is superior in treating SUAP.

Objective To evaluate clinical effect of simultaneous kidney-pancreatic transplantation(SKPT) with portal venous and enteric drainage. Method Between June 2001 and June 2004, six insulin-dependent diabetes mellitus(IDDM) and renal failure patients underwent this procedure. The venous drainage of the graft was established between donor′s portal vein and recipient′s superior mesenteric vein. The exocrine secretion was drained into proximal jejunum via side-to-side anastomosis between donor′s duodenum and recipient′s proximal jejunum. Steroids, mycophenolate mofetil, tacrolimus and Zenapax were used as immunosuppressants. Results Procedures were successful in all 6 cases. Excellent renal function and euglycemia were achieved in 4 cases. Follow-up of 4-34 months on the 4 survivers found excellent kidney-pancreatic function without any rejection episode. Two patients died perioperatively due to sepsis secondary to pancreatic leakage and drug toxicosis of excessive FK506. Conclusion Our preliminary experience suggests that simultaneous pancreas-kidney transplantation with enteric and portal drainage is reliable procedure for the treatment of IDDM with renal failure.

Objective To detect the argyrophilic proteins in nucleolar organizer regions(Ag-NORs) that express rDNA and rRNA proliferation of T lymphocytes before chemotherapy and after complete remission(CR) in children with primary acute leukemia(AL).Methods The argyrophilic granules area of NOR/nuclear area(I.S%) of T lymphocytes was detected by image analysis system in peripheral blood of 42 patients before chemotherapy and after CR and 30 normal children.Results I.S% in the patients before chemotherapy(5.06%?1.36%) were significantly lower than those in the healthy donors(7.51%?1.06%)(t=8.238 P0.05).Conclusion These results suggest that decrease of Ag-NORs expresses the evidence for tumour induced suppression of immune function of T cells in children with AL prior to treatment.
