The scientific research fund is an important resource for carrying out the scientific re-search projects effectively. Whether it can be reasonable used not only relates to the fulfilled quality, bene-fit, using direction and quantity, but also makes the reformation of management methods inevitable with the increase of quantities of the projects and funds. By summarizing the previously practical experiences, this paper explored the network managements of scientific research funds based on workflow in the hospital. By means of computer and network, the concept of workflow was further introduced to the application of platform of scientific research funds management. It embodies the charactor of approval flow in workflow management system. Finally the data of scientific research funds can be shared and integrated into multi-departments, so it is beneficial to improve the fund's benefit and strengthens the supervision in the whole process manage-ment.

Autocrine motility factor (AMF) plays an important role in the stimulation of the migration and motility of cells, especially the generation, migration and angiogenesis of tumor. Recently, it has been found that AMF has three isoforms, ATX-t, ATX-m and PD-I alpha. The PD-I alpha isoform is specifically expressed in the brain, which plays extensive functions in nervous system, such as regulating neural development and differentiation, promoting neurotrauma repair, inducing neuropathic pain, even contributing neurodegeneration under some circumstances. This indicates the close relationship of AMF/AMFR and the pathophysiology of the nervous system. This paper mainly reviews the function of AMF and AMFR and its possible mechanism in the nervous system.

Objective To establish a simple and stable orthotopic segmental small bowel transplantation model in rats.Methods Eighty male SD rats were divided into donors and recipients.Orthotopic segmental small bowel transplantation was performed by end-to-side anastomosis between donor abdominal aorta tundish-shape patch with arteria mesenterica superior pedicle and abdominal aorta of the recipients; end-to-end anastomosis between the portal vein of the donors and the left renal vein of the recipients was done using the cuff technique ; the large part of the small bowel of the recipients was excised,and it was replaced by the segmental intestine of the donors.Results The operation time of the donors and recipients were (40 ± 5) minutes and (50 ±8)minutes,respectively.The warm ischemia time and cold ischemia time were (5 ± 2) minutes and (15 ± 5) minutes,respectively.The anastomosis time of arteries and veins were (5 ± 2) minutes and (4 ± 2) minutes,respectively.The survival time of 90.0％ (36/40) of rats was more than 10 days.Conclusion The modified rat model of orthotopic segmental small bowel transplantation is easy to manipulate,and has the advantages of short operation time,high survival rate and stability.

Die Prim?rstabilit?t von Pedikelschrauben im Knochen h?ngt in hohem Masse von der Knochendichte ab. Die Augmentation mit Zement ist ein klinisch einsetzbares Verfahren, um die Schrauben-Verankerung im osteoporotischen Knochen zu verbessern.In dieser Studie wurde eine neuartiges resorbierbares Knochenersatzmaterial (α-BSMTM) für diese Augmentation benutzt. Biomechanische Testungen wurden in vitro bei 16 Lendwirbelkorpern (L3-L5) aus 6 Individuen(75,2±13,7 Jahre) durchgeführt. Vor der biomechanischen Testung wurde bei allen Pr?paraten die trabekul?re Knochendichte mittels pQCT gemessen und beide Pedikel mit USS-Pedikelschrauben (5,0 mm × 45 mm) besetzt, von welchen eine mit α-BSMTM augmentiert war. Beim axialen Auszugstest wurden die maximale axiale Auszugskraft (F-max) sowie die Energieaufnahme bestimmt. Der Medianwert der F-max stieg beim Auszugstest durch die Zementierung mit α-BSMTM um 80 % von 370 N (ohne Zement) auf 665 N (mit Zement). Die Energieaufnahme bis zum Erreichen der F-max (E-F-max) und bei Dislokation bis 2,0 mm (E-2 mm) steigerte sich ebenfalls um 83 % und 68 %. Die Unterschiede waren signifikant. (Wilcoxon′s-Test, P<0,01) Die Ausreisskrafte F-max (ohne oder mit Zement) korrelierten eng mit der Knochendichte (r=0,9056 und r=0,9585). Unsere Resultate zeigen, da eine Augmentation mit dem α-BSMTM die prim?re Stabilit?t von Pedikelschrauben verbessern kann. Der Effekt scheint auf einer Optimierung der Kontaktfl?che und einer Aussteifung der schraubennahen Spongiosa zu beruhen. Das Material konnte geeignet sein, die Verankerung von Pedikelschrauben bei osteoporotischen Patieten zu verbessern.

In recent years,with in-depth study of bladder sensation related mechanisms,numerous ion channels,neurotransmitters and nerve receptors have been found to participate in the regulation of bladder sensation,including TRPV,P2X and Piezo,as well as CBR and HCN.Thanks to the relevant research on the neural signal pathway from the cerebral cortex to the bladder wall and the maturity of clinical measurement methods for bladder sensation,we can further study the abnormal bladder sensation in patients with overactive bladder(OAB),so as to explore its mechanism.Bladder hypersensitivity,as one of the current research hotspots,is receiving increasing attention from researchers.This article reviews the mechanism of bladder hypersensitivity from the aspects of clinical measurement methods of bladder sensation,ion channel,neurotransmitters and nerve receptors related to bladder sensation,in order to explore its significance in the pathogenesis of OAB.

Objective:The purpose of this study was to investigate the IgG antibody levels of whooping cough, diphtheria, and tetanus in pregnant women in Nanshan District.Methods:From January to March 2019, 495 pregnant women who met the inclusion criteria in a hospital in Nanshan District, Shenzhen were selected as the survey subjects. The enzyme-linked immunosorbent assay was used to detect serum levels of pertussis, diphtheria, and tetanus IgG antibodies and we compared the differences in antibody levels of pregnant women with different characteristics.Results:The maternal age was (29.23±4.08) years old. The geometric mean concentration of pertussis antibody was 2.589 (1.172-4.953) IU/ml, 1.01% (5 cases) of pregnant women had pertussis antibody concentration ≥ 40 IU/ml, and 75.15% (372 cases) of pregnant women had pertussis antibody concentration<5 IU/ml. The GMC value and antibody positive rate of diphtheria in pregnant women were 0.024(0.009-0.065) IU/ml and 72.53% (359 cases), respectively. The GMC value and antibody positive rate of tetanus in pregnant women were 0.014 (0.006-0.034) IU/ml and 53.74% (266 cases), respectively. There was no statistical difference in the antibody level and antibody positive rate among pregnant women of diphtheria and tetanus, respectively.Conclusion:The concentration of antibodies against pertussis, diphtheria, and tetanus in pregnant women are all at a low level, which is not enough to protect themselves from disease infection.

Objective To analyze and compare the clinical manifestations and imaging features of children with secondary massive cerebral infarction after acute subdural hematoma(ASDH),and to evaluate its potential risk factors in order to provide evidence for the prevention,early diagnosis and early treatment of secondary massive cerebral infarction after ASDH.Methods The clinical data of children with ASDH aged 4～12 years were retrospectively studied.All the children received routine operation.The diagnosis of post-traumatic secondary massive cerebral infarction(MCI)was based on low-density areas on CT images and clinical signs.Clinical and radiographic findings related to patient outcomes were reviewed and statistically compared.Univariate and multifactor Cox regression analysis was used to evaluate the MCI after operation to obtain the factors affecting MCI.Results A total of 67 cases were included in the study,with 32 cases included in the MCI group and 35 cases included in the non-MCI group.There were significant differences between MCI and non-MCI groups in age(t=2.016,P= 0.048),body mass(t=2.389,P=0.020),multiple injuries(χ2=11.121,P=0.001),GCS(Z=-4.730,P＜0.001),hematoma volume(χ2=12.890,P=0.002),MLS(χ2=12.261,P=0.002)and perioperative shock(χ2= 14.417,P＜0.001).GCS(OR=0.322,P=0.002),perioperative shock(OR=10.992,P=0.007),multiple injury(OR= 6.547,P=0.046)and MLS score(OR= 46.974,P=0.025)were major risk factors for MCI in children with ASDH.Conclusion Perioperative shock,multiple injuries,low GCS and MLS greater than 10mm are risk factors for MCI.The incidence of MCI is significantly increased in children with multiple risk factors.
