The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

Objective To evaluate the role of mierosurgery in surgical treatment to urethrocutaneous fistula after urethroplasty in hypospadias and improve surgical results.Methods From 1999 to 2006,44 urethrocutaneous fistulae (more than 3mm in diameter) after urethroplasty for hypospadias in 33 patients were repaired with different skin flaps.For example,Thiersch technique,urthroplasty,etc.Microsurgical tech- nique was employed in every case.Results The success rates of different procedure were 84.8% (28/33) for Thiersch technique,100% (11/11) for urethroplasty respectively.The total success rate was 88.6%(39/ 44).Conclusion It's just application of skin flap for repairing of big or complex urinary fistula after hypos- padias surgery.The application of microsurgical technique can increase success rate.It is necessary to excise scar and partial urethra for hypospadias fistula combined with urethral structures,cicatricial eontracture and in- curvation of penis.Rich blood-supply,low tension and atraumatic technique are all very important to improve surgery success rates of urinary,fistula after hypospadias repair.

Aim: To compare the stability of Endostar~(TM) and endostatin under different temperatures and pH using polyacrylamide gel electrophoresis( PAGE) and Western blot and to compare the activity of Endostar kept at 4 ℃ and 37 ℃ by inhibition of endothelial cell proliferation. Methods: Endostar and endostatin expressed by Phicha pastoris were kept at 4 ℃, and 37 ℃ for 96 hours, respectively. The electrophoresis of the samples was detected by reduced and non-reduced PAGE. The results were further confirmed by Western blot with rabbit anti-Endostar polyclonal antibody. The inhibitory effect of Endostar stored at different temperatures on HUVEC was also exam-ined by cell-based assay. Results: Single band at 20 kD was detected in all lanes of SDS-PAGE gel loaded with endostatin and Endostar samples under reducing condition. In acidic native PAGE with three different pH values, endostatin showed a smear characteristic, whereas Endostar showed a unique band in acidic non-continuous native PAGE. Although the smear phenomenon was also observed under two conditions of constant native elec-trophoresis, the major band of Endostar could be detected. Similar electrophoretic behavior was found for endosta-tin and Endostar stored at both 37 ℃ and 4 ℃ . Western blot showed similar results to those by PAGE. Furthermore, Endostar stored at these two temperatures also had identical inhibitory effect on proliferation of HUVEC. Conclusion: Endostar and endostatin exhibit similar thermostability at regular conditions, but Endostar was more stable than endostatin expressed in P. pastoris under acidic condition.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.
METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.
RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.
CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

Permeabilized cells containing trehalose synthase from Meiothermus sp.CBS-01 was immobilized by the integration of entrapment in alginate beads with cross-linking and electrostatic self-assembly coating technique.Coating on alginate beads with diazo-resin and poly(styrene sulfonate) can protect the beads from degradation in phosphate buffer,whereas cross-linking with carbodiimide improves the thermostability of trehalose synthase entrapped in alginate beads.By co-immobilization of permeabilized cells using entrapment-cross-linking- coating method,the enzyme recovery was 32%,and the optimum temperature of the enzyme was still 60℃,but the optimum pH was shifted from 6.5 to 7.In batch manner,a maximum conversion yield of 60% trehalose from maltose could be reached by the immobilized cells.Within 4 times repeated use of the immobilized cells,and each time was operated at 50℃ for 24h,more than 50% conversion yield of trehalose could be maintained with less than 20% loss of the enzyme activity.

Purpose:Thalamic hemorrhage breaking into ventricles (THBIV) is a devastating disease with high morbidity and mortality rates.Endoscopic surgery (ES) may improve outcomes,although there is no consensus on its superiority.We investigated the efficacy and safety of ES and compared the outcomes of different management strategies by ES,hematoma puncture and drainage (HPD),and external ventricular drainage (EVD) in patients with THBIV.Methods:We retrospectively analyzed patients with THBIV treated by ES,HPD,or EVD at our hospital from June 2015 to June 2018.Patients were categorized into anteromedial and posterolateral groups based on THBIV location,and then the two groups were further divided into ES,HPD,and EVD subgroups.Individualized surgical approach was adopted according to the location of the hematoma in the ES subgroups.Patient characteristics and surgical outcomes were investigated.Results:We analyzed 211 consecutive patients.There were no significant differences in clinical characteristics or incidence of perioperative procedure-related complications (postoperative rebleeding and intracranial infection) in either anteromedial or posterolateral groups.Compared with other therapeutic methods,the ES subgroups had the highest hematoma evacuation rate,shortest drainage time,and lowest incidence of chronic ventricular dilatation (all p < 0.05).Among the three anteromedial subgroups,ES subgroup had the best clinical outcomes which was assessed by the modified Rankin Scale,followed by HPD and EVD subgroups (p < 0.01);while in the posterolateral subgroups,clinical outcomes in the ES and HPD subgroups were similar and better than that in the EVD subgroup (p =0.037).Conclusion:Individualized surgical ES approach for removal of thalamic and ventricular hematomas is a minimally invasive,safe,and effective strategy for the treatment of THBIV with a thalamic hematoma volume of 10-30 mL.
