Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.

Objective To explore the application effect of a new lighted surgical aspirator in deep brain hematoma removal operation.Methods Totally 153 patients of non-traumatic basis festival area cerebral hemorrhage were randomly divided into a control group and a treatment group.Both the groups underwent clearance of intracranial hematoma and decompressive craniectomy surgical operation in the operating room,with the common aspirator involved in the control group and the lighted one in the treatment group.Results There was no significant difference between the rates of hematomal removal in the groups (P＞0.05).The treatment group had the operating time less by 59.85 min and the hospital stay decreased by 15.23 d than those in the control group (P＜0.05).The GOS score and daily viability of the treatment group was also statistically higher than those of the control group (P＜0.05),and the effective rate in the treatment group was also more than that in the control group by 24.9％ (P＜0.05).Conclusion The new aspirator solves the problems in visual field and light source,decreases the operating time and improves the disease prognosis.

Objective To establish an animal model of severe blast lung injury in baby rabbits,and to provide a way to study the char-acteristic and treatment of blast lung injury in minors.Methods Randomly selected sixteen 4-weeks old New Zealand white rabbits,and the blast lung injuries were made by BST-Ⅰ biological shock tube with different drive pressure (4.0 MPa and 4.5 MPa)respectively.Then compared the injury severity of the 4.0 Mpa group and the 4.5 MPa group.Selected forty-eight 4-weeks old New Zealand white rabbits and di-vided them into the control group (8 rabbits)and the blast lung injury group (40 rabbits)Rabbits in the blast lung injury group were injured with 4.5 MPa drive pressure.Observed the vital signs,physiological index,gross anatomy of the lung,pathology,and pulmonary water content at the time of injury immediately (0 hour),2 hours,4 hours,6 hours,12 hours,24 hours,48 hours and 72 hours after the injury.Results Rabbits inthe 4.0 Mpa group and the 4.5 MPa group were all alive.The overpressure of blast wave of the 4.0Mpa group was (328.16 ± 4.78)kPa,rate of severe pulmonary defense was 12.5%,and the AIS score was (3.38 ±0.52)points.In the 4.5 MPa group,the overpressure of blast wave was (395.04 ±11.74)kPa,rate of severe pulmonary defense was 87.5%,and the AIS score was (4.13 ±0.64) points.Rabbits in the control group and the blast lung injury group were all alive.The spirits of rabbits were drooping immediately after inju-ry,and it last about 0.5 hour.Then the breathing and heart rate was accelerated,pulmonary water content was increased significantly,and there were extensive hemorrhage and edema in the lung.Most of the rabbits suffered severe lung injury,and the AIS score was (3.98 ±0.55) points.Lung tissue rupture,hemorrhage,edema,and inflammatory cells infiltration were the main pathological manifestations under light microscopy. Conclusion The model of severe blast lung injury in baby rabbits could be established with BST-Ⅰbiological shock tube and drive pressure of 4.5 MPa.It is relatively simple,easily controllable and highly repeatable,which can be used as a feasible model for the study of blast lung injury.

Objective: To analyze the long-term prognosis of re-operation in patients with functional tricuspid regurgitation (FTR) after left sided valve replacement (LSVR) and hence evaluate the optimal timing of mentioned re-operation. Methods: A total of 59 FTR patients who had re-operation after their prior LSVR in our hospital from 1999-01 to 2013-01 were analyzed. The clinical information and post-operative follow-up results were recorded in all patients. Results: There were 5/59 (8.5%) patients died in peri-operative period and the overall post-operative mortality was 11.9% (7/59). The follow-up data of 54 survivors were available for the mean time of 51.1 (21-188) months. There were 19/54 (35.2%) patients suffered from MACE and 30 (55.6%) were beneifted by improved cardiac function. Uni-variable analysis indicated that pre-operative NYHA class IV (P=0.008), pre-operative right ventricular (RV) dysfunction (P=0.037), concomitant left-sided redo-operation (P=0.017) and TVR operation (P=0.002) were associated with all cause mortality of tricuspid re-operation. Multi-variable Cox regression analysis showed that pre-operative RV dysfunction was the only independent risk factor of long term MACE-free accumulating survival rate (HR=3.0, 95% CI 1.11-8.2,P=0.031); while TVR operation (HR=12.8, 95% CI 1.53-107.02,P=0.019) and pre-operative NYHA class IV (HR=5.3, 95% CI 1.20-24.51,P=0.032) were the independent risk factors for long-term mortality in patients after tricuspid re-operation. Conclusion: Patients with compensatory RV function showed better long term prognosis after secondary tricuspid operation. Aggressive re-operation before the occurrence of right ventricular dysfunction could be beneficial for relevant patients.

OBJECTIVEAutologous peripheral blood stem cell transplantation (APBSCT) is an important method for treatment of malignant solid tumors in children. The mobilization and collection of blood stem cells is crucial for APBSCT. This study aimed to evaluate the clinical efficacy of mobilization and collection of blood stem cells by CIE or IEV chemotherapy protocol in APBSCT in children with neuroblastoma (NB) or rhabdomyosarcoma.

METHODSThe protocols of CIE (cisplatin, etoposide) and IEV (vincristine, dosfamide, etoposide) were used as mobilization chemotherapy in 8 cases of NB with stage IV and 3 cases of rhabdomysacoma with stage III, respectively. The results of the mobilization of blood stem cells were observed.

RESULTSOf the 11 cases, mononuclear cells (MNC) and CD34+ cells were successfully collected and the volume of MNC and CD34 averaged (5.55 ± 1.43)× 10(8)/kg and (4.88 ± 2.48) × 10(6)/kg, respectively. No severe complications were observed during the mobilization and collection. A rapid hemopoietic reconstitution was observed in 10 children after APBSCT. One with NB out of the 10 children died of left heart failure 32 days after APBSCT. Others (9 cases) showed a nearly normal result of routine peripheral blood test 60 days after APBSCT.

CONCLUSIONSCIE or IEV protocol is effective and safe for the mobilization and collection of peripheral blood stem cells in children with NB or rhabdomysacoma.

The change of the effective components (liquiritin, glycyrrhizic acid, liquiritigenin, isoliquiritigenin) contents of Glycyrrhizae Radix et Rhizoma (GRR) before and after compatibilities in Sini decoction was studied in this paper. Taking single GRR decoction, GRR-Aconiti Lateralis Radix Praeparata (ALRP) decoction, GRR-Zingiberis Rhizoma (ZR) decoction and Sini decoction as test samples, the contents changing of the four effective components of GRR were measured by HPLC. The results showed that the contents of the four effective components of GRR in the single GRR decoction was higher than that in other samples, and the sequence was single GRR decoction > GRR-ZR decoction > GRR-ALRP decoction > Sini decoction. The contents of liquiritin were 11.18, 9.89, 9.67, 9.17 mg · g(-1); the contents of glycyrrhizic acid were 20.76, 15.58, 11.30, 8.52 mg · g(-1); the contents of liquiritigenin were 0.66, 0.57, 0.45, 0.24 mg · g(-1); the contents of isoliquiritigenin were 0.14, 0.07, 0.03, 0.01 mg · g(-1). Therefore, the effective components of GRR decreased obviously after GRR compatibility with ZR providing scientific basis for GRR relieving the strong nature of ZR. The effective components of GRR decreased sharply after GRR compatibility with ALRP providing scientific support for the material foundation research of GRR reducing the toxicity of ALRP. The effective components of GRR decreased further in Sini decoction indicating that the three medicines in Sini decoction were interactional, which reflecting the scientific connotation of the mutual-restraint/mutual-detoxication, mutual-promotion/mutual-assistance compatibilities in Sini decoction.
