Objective: To provide a new manufacturing method for the artificial seeds of Dendrobium officinale. Methods: The artificial seeds were manufactured by taking protocorms of D. officinale as the materials entrapped with the consideration of the effects of testa components and artificial endosperm on the germination and seedling of the artificial seeds. Results: The better conditions of the artificial seeds are manufactured in the fundamental artificial endosperm made by MS + 0.5 mg/L BA + 0.5 mg/L NAA +3 g/L AC + 30 g/L sodium alginate + 3 g/L chlorothalonil mixture reacted in 2% CaCl2 for 15 min; For the higher germination and seedling rate, 15 g/L cassava starch and 10 g/L water retaining agent can be added into the artificial endosperm components, respectively; For the higher germination rate, 10 g/L nano-SiO 2 (better planting rate) and 10 g/L Nano-TiO2 can be added into the artificial testa, respectively. The highest seedling rate was obtained by adding 10 g/L nano-SiO2. Conclusion: A manufacturing method of the artificial seeds of D. officinale has been established for the higher germination and seedling rates.

Objective To measure the levels of serum transferrin receptors (sTfR) and serum ferritin (SF) in children with hemoglobin H disease for investigation the iron metabolism(sideropenic or iron overload) and to guide the proper intervention.To get a best index of judging the iron overload in HbH children by analysis of the values of sTfR and sTfR/lgSF.Methods Peripheral blood specimens were obtained from 50 cases of HbH children and 30 cases of healthy normal controls,the levels of sTfR and SF were examined by enzyme linked immunosorbent assays(ELISA).The diagnosis efficiency of sTfR and sTfR/lgSF in HbH children′s iron metabolism was judged by receiver operator cha-racteristic (ROC) curve analysis.Results The level of sTfR in HbH group was (6.74?1.02) mg?L-1,which was significantly lower than that in healthy control group[(8.09?0.67) mg?L-1](P

Objective To investigate the prevention and mechanism of Extracorporeal shock wave lithotripsy(ESW) induced renal Injury by pre-treating kidneys with low-energy shock waves(LESW).Methods Forty healthy female domestic rabbits were surgically managed to the mono-nephron models and random divided into 4 groups consisting of ten each: Control,LESW,ESW and ESWL plus LESW pretreated groups.LESW group received 100 LESW,ESW group received 1500 standard ESW,and same dose on ESW group except 100 LESW pretreatment in ESW plus LESW pretreated group.The rabbit kidney tissues were obtained 24 hours after ESW.Activity of superoxide dismutase(SOD) and malondialdehyde(MDA) levels in the renal tissue,and the level of N-acetyl-β-D-glucosaminidase(NAG) in urinary were measured.Renal cell apoptosis was detected by TdT-mediated dUTP Nick End Labelling(TUNEL).Results The MDA,the urinary level of NAG and rate of apoptosis in the LESW groups were reduced(P<0.01),and the activity of SOD increased significantly(P<0.05) as compared with ESW group,and these changes in LESW group had no statistics difference compared with the control group(P>0.05).Conclusions LESW pretreatment protocol substantially limits the renal injury that often caused by ESW.LESW may suppress oxidative stress and antagonize the process of renal cellular apoptosis.

Objective To study the impact of preprocedure intravenous urography (IVU) on the extracorporeal shock wave lithotripsy(ESWL) for proximal ureteral stones.Methods One hundred patients with solitary radiopaque proximal ureteral stones on plain radiographs and no severe hydronephrosis on ultrasonographic examination were allocated randomly to two treatment groups.IVU group (n=50) had IVU before the start of ESWL,whereas patients in control group (n=50) underwent ESWL without IVU.Postop- erative success,the stone-free rates and complications were evaluated in both groups. Results Seven patients in IVU group were excluded from the study. The success rate [95.3%(41/43) in IVU group vs 94.0% (47/50) in control group],stone-free rate [83.7% (36/43)vs 86.0% (43/50)] and complication rate[27.9% (12/43 ) vs 26.0% (13/50)]were similar in two groups (P＞0.05).Conclusions It is not necessary to obtain an IVU for patients who have solitary radiopaque proximal ureteral calculi on plain radiographs with no severe hydronephrosis on uhrasonographie examination before scheduling them for ESWL,thus minimizing the cost,avoiding exposure to contrast medium,and reducing radiation exposure.
