Objective: To prepare a blood deficient model and study the effect of Tangkuei Blood Supplementing Decoction on hemopoiesis in this model. Methods: This model was made in mice by i.p. an accumulate doses of 60mg/kg acetylphenylhydrazine (APH) and 160mg/kg cyclophosphamidum (CY). The RBCs, WBCs, reticulocytes and bone marrow nucleated cells (BMNC) were counted, the micro structure of bone marrow was observed. The swimming time, the body temperature and the plasma cAMP, cGMP levels were measured. The effects of Tangkuei Blood Supplementing Decoction by p.o. administration on promoting the hemopioetic function were observed with the model mice. Results: Tangkuei Blood Supplementing Decoction could remarkably increase RBC, WBC, BMNC, improve the proportion of reticulolytes in peripheral blood and the micro struture of bone marrow, prolony the swimming time, raise the body temperature and the specific value of cAMP/cGMP. Conclusion: The model exhibits the main features of blood deficiency, and can be used as one of models of blood deficiency. Tangkuei Blood Supplementing Decoction can obviously improve the dual deficiention of qi and blood of model mice by supplementing qi and blood.

Objective To investigate the methods of repair the lateral skin and soft tissue defect of the middle and rear foot with the plantar medial flap transferred before the achilles tendon.Methods Fifteen cases with the lateral skin and soft tissue defect of the middle and rear foot were repaired with the plantar medial flap pedicled with posterior tibia artery transferred before the achilles tendon from January,2012 to October,2015.All the 15 patients were followed up in the way by telephone or back to hospital postoperatively 3 months to 3 years,including 6 cases by telephone follow-up and 9 cases of back-to-hospital follow-up,to observe the appearance,functions of the skin flap and whether the skin flap survived well.Results The flaps of 15 cases survived well.Postoperative followup of 3 months to 3 years,the sensation of the flap was good,without any ulcer or necrosis.The patients walked well and were satisfied with the flap.Conclusion To repair the lateral skin and soft tissue defect with the plantar medial flap transferred before the achilles tendon as a new method is feasible with the good ability of faster sensory recovery,the good appearance and function.

Objective To investigate the methods and results of hand reconstruction by transplanting the fostered residual finger and the second toe,which share the same blood supply system.Methods From January,2014 to January,2016,3 cases with destructive hand injuries in our hospital;and debridement was performed in one session during the early stage of trauma,with skin grafting to cover the wrist stump and foster the residual finger to a branch of the dorsalis pedis artery.The first dorsal metatarsal artery around the toe web was identified and then gradually isolated proximally with dissection of the branches of the dorsalis pedis artery supplying the fostered finger until the convergence of the two blood vessels.Then,reconstructed hand by residual finger and combined second toe transplantation.Results After a follow-up period of 3 months to 2 years,the reconstructed hand had a good appearance and was able to complete basic mundane actions.The function of the limb was restored to a large extent andthe patient was satisfied with the reconstructed hand.Conclusion Transfer of a fostered residual finger and combined second toe which have the same blood supply system for hand reconstruction as a new method need to anastomose only one set of arteries,and it is feasible with the good appearance and function of the reconstructed hand.

Objective To find out and clone the genes that can influence different willis circle in Meriones unguiculatus, the genomic library has been made.Methods 96 clean Meriones unguiculatus were dissected according to observe the differences of willis circle, and the mixed DNA was extracted from different blood vessels.The genomic library construction has been done by using pCC1FOS vector, following by CopyControl Fosmid Lib manual.The copy numbers, recombined segment size and recombination fraction of the library were measured.Results Genomic library of different Willis circle in Meriones unguiculatus was successfully made.The capacity of the library was 1700 copies.The segment size was 36kb, and the recombination fraction was 93%.Conclusion The library was the good beginning for the following steps which were gene cloning and genescreen.

Objective To investigate the hepatic hemodynamic characteristics of cirrhotic patients with splenectomy using iodine map of dual-source computed tomography(DSCT).Methods Twenty-four cirrhotic patients with splenectomy were selected as a study group,41 cirrhotic patients without splenectomy as a cirrhosis group and other 32 patients with normal liver as a control group.The iodine concentration(IC)in hepatic arterial and venous phases was measured on the iodine map,and the arterial iodine fraction(AIF)and portal venous iodine concentration(PVIC)were calculated.Receiver operating characteristic(ROC)curves were plotted and the area under the curve(AUC)was recorded to evaluate the diagnostic efficacy of each parameter using the DeLong test.Results IC in arterial phase and AIF were significantly higher,and IC in venous phase and PVIC were significantly lower in study group(P<0.05).The AUC values of the four parameters between study group and cirrhosis group were 0.735,0.992,0.943,and 0.994,respectively.Conclusion DSCT iodine map is helpful for clinical quantitative assessment of hepatic hemodynamic characteristics in cirrhotic patients with splenectomy,and the PVIC has optimal independent diagnostic performance.

Objective To analyze influences of the braiding angle and material on performance of ventricular septal defect (VSD) occluders, so as to provide theoretical basis and guidance for their design. Methods The finite element models of occluders with different braiding angles (30°, 45° and 60°) were developed respectively. The radial supporting and axial bending performances of nickel titanium (NiTi) occlude and poly-p-dioxanone (PPDO) occlude were then compared. Results Under 5 kPa radial loading, radial stiffness of the 30°, 45° and 60° NiTi occluder waists were 8.60, 1.51 and 0.99 mN/mm3,respectively, while that of 45° PPDO occluder waist was 7.35 mN/mm3. Under axial bending of 0.5 rad, the maximum radial deformation of the 30°, 45°, 60° NiTi occluder waists were 1.17, 1.24 and 0.22 mm, while that of the 45° PPDO was 0.54 mm. Conclusions Under the condition of using the same material, occluders with braiding angle of 60° show the lowest radial stiffness, indicating they have the best radial supporting ability. Furthermore, they also show the smallest maximum radial deformation, indicating they have the best axial bending ability and the compliance. On the other hand, under the condition of using the same braiding angle, NiTi occluders show lower radial stiffness, indicating they have better radial supporting ability. However, PPDO occluders show lower maximum radial deformation, indicating they have better axial bending ability and compliance.

Oligoasthenozoospermia is the main cause of male infertility， with complex and diverse causes. Currently， there are still some unclear causes of oligoasthenozoospermia in clinical practice， known as idiopathic oligoasthenozoospermia. With the development of high-throughput sequencing technology， it has been found that intestinal microbiota disorder may be an important promoting factor for the onset of oligoasthenozoospermia. Traditional Chinese medicine believes that "deficiency of kidney essence" is the core pathogenesis of oligoasthenozoospermia. In clinical practice， the method of tonifying the kidney and strengthening the essence has a significant therapeutic effect on oligoasthenozoospermia， but its mechanism of action has not been fully elucidated. Based on the basic theories of traditional Chinese medicine and molecular biology research， it has been found that there is a similarity between "kidney essence" and intestinal microbiota. During the onset of oligoasthenozoospermia， the disorder of intestinal microbiota has similarities with the pathogenesis of "deficiency of kidney essence" in traditional Chinese medicine. Moreover， traditional Chinese medicine for tonifying the kidney and strengthening the essence can regulate the disorder of intestinal microbiota， which may be one of the effective mechanisms for the treatment of oligoasthenozoospermia with the Bushen Yijing method. Based on this， this article explored the mechanism of Bushen Yijing method of traditional Chinese medicine in treating oligoasthenozoospermia from the perspective of intestinal microbiota， so as to provide new ideas for the treatment of oligoasthenozoospermia with traditional Chinese medicine.
