Objective To explore the value of miniprobe sonography (MPS) in differentiating Crohn??s disease (CD) and ulcerative colitis (UC). Methods 46 patients with active inflammatory bowel disease (IBD) were included into the patient group (16 patients with CD and 30 cases with UC). 20 healthy cases ( underwent physical examination in outpatient department) were recruited as the control group. All cases underwent MPS and high sensitive C-reactive protein (Hs-CRP) test.The MPS measurement index include thetotalwallthickness(TWT), mucosal thickness (MT), submucosal thickness (SMT), muscularispropria thickness (MPT), and the number of enlarged colic and paracolic lymph nodes. Results TheTWT, M, SM, MP(mm)and Hs-CRP(mg/L)in CD, UC and control group are 5.84 ± 1.42, 1.48 ± 0.23, 1.88 ± 0.28, 2.31 ± 0.85, 40.58 ± 19.33, 4.74 ± 1.01, 1.79 ± 0.35, 1.41 ± 0.25, 1.32 ± 0.34, 22.41 ± 15.25,2.86 ± 0.23, 0.97 ± 0.13, 1.06 ± 0.11, 0.64 ± 0.0 and 1.70 ± 0.65. TWT, MT, SMT, MPT and Hs-CRP in UC group has significant different with those in controp group(P<0.05). The mean value of TWT, MT, SMT, MPT and Hs-CRP in CD group are higher than those in UC group. M in UC group is higher than that in CE group. The difference is significant(P<0.05). 5 cases in CD and 2 cases with UC had enlarged colic or paracolic lymph nodes. Conclusions The MPS can distinctly observe the changesof different colonic tissue layers and the surrounding tissue structures in IBD patients,which helps for distinguishing active CD from UC.

OBJECTIVESTo discuss the new classification of epididymal malformation in cryptorchidism.

METHODSOne hundred and fifty-three boys who were two to four year old underwent orchidopexy for cryptorchidism and 144 hydroceles who were two to eight year old were enrolled into control. Based on the observation of the status between testis and epididymia, the length of epididymis and the configuration of epididymis as well as spermaduct, we divided epididymal malformations in cryptorchidism into three types. Type I: obstruction of sperm transport, including I A, I B and I C; Type II: possible obstruction of sperm transport, defined by II A and II B; Type III: no obstruction of sperm transport, classified into III A and III B.

RESULTSThere were 47 (23.4%) out of 201 undescended testes with malformation of epididymides and 16 (10.3%) out of 155 testes in the control(P < 0.05). 11 of 48 cases of bilateral cryptorchidism had the same malformations, with 2 cases of type IB, 2 of IC, 1 of II A, 4 of III A and 2 of IV B underwent orchidopexy or orchiectomy.

CONCLUSIONSThese data showed that the incidence of epididymal abnormalities in cryptorchidism was higher than that in the hydroceles and it's not essential to have orchiectomy unlimitedly to serious epididymal abnormalities.

BACKGROUNDAlthough heart transplantation has become a standard therapy for end-stage heart disease, there are few published studies regarding the use of transplant organs from marginal donors. Here we describe the clinical outcome we have obtained using marginal donor hearts.

METHODSWe analyzed 21 cases of orthotopic heart transplantation for end-stage heart disease performed in our department between September 2008 and July 2010. Of these patients, six received hearts from marginal donors and the remainder received standard-donor hearts. The two groups were compared in terms of both mortality and the incidence of perioperative complications such as infection, acute rejection, and right heart insufficiency.

RESULTSThe 1-year survival rate of both groups was 100%. Only one death was recorded in standard-donor group during follow-up. Patients who received marginal donor hearts (83%) experienced more early complications than did the standard-donor-heart group (13%), but the mortality of the two groups was the same. The duration of post-ICU stay was greater in the marginal donor group than in the standard-donor group, (35.5 ± 17.4) days and (21.7 ± 2.6) days, respectively (P < 0.05).

CONCLUSIONSThe use of marginal donor hearts increases the number of patients who can receive and benefit from transplants. However, it may introduce an increased risk of early complications, thus care should be taken both in the choice of patients who will receive marginal donor hearts and in the perioperative treatment of those for whom the procedure is performed.

BACKGROUNDMyocardial infarction results in tissue necrosis, leading to cell loss and ultimately to cardiac failure. Implantation of skeletal muscle satellite cells into the scar area may compensate for the cell loss and provides a new strategy for infarct therapy. Vascular endothelial growth factor (VEGF) is a promising reagent for inducing myocardial angiogenesis. Skeletal myoblast transplantation has been shown to improve cardiac function in chronic heart failure models by regenerating muscle. We hypothesized that VEGF expression and vascular regeneration increased in infarcted myocardium by skeletal muscle satellite cells, which can promote vascular producing and improve survival environment in infarcted myocardium.

METHODSThe skeletal muscle satellite cells were implanted into the infarcted myocardium in a model through ligated left anterior artery in Louis Inbrad Strain rat. Specimens were got for identifying the expression of VEGF and the density of vascular by immunochemical method at two weeks after implantation.

RESULTSThe proliferation and differentiation of the skeletal muscle satellite cell was very well. The expression of VEGF was higher in the implanted group (146.83 +/- 2.49) than that in the control group (134.26 +/- 6.84) (P < 0.05). The vascular density in the implanted group (13.00 +/- 1.51) was also higher than that in the control (10.68 +/- 1.79) (P < 0.05).

CONCLUSIONThe implanted satellite cell could excrete growth factor that would induce angiogenesis and improve cell survival environment in infarcted myocardium.

OBJECTIVE: Larotaxel is a new chemical structure drug, which has not been marketed worldwide. Accordingly, the standard identification and quantification methods for larotaxel remain unclear. The spectrometric analyses were performed for verifying weight molecular formula, molecular weight and chemical structure of larotaxel. Besides, a quantification method was developed for measuring larotaxel in the liposomes. METHODS: The molecular formula, molecular weight and chemical structure of larotaxel were studied by using mass spectrometry (MS), infra-red (IR), nuclear magnetic resonance (NMR) and ultraviolet-visible (UV-vis) spectrometric techniques. The absorption wavelength of larotaxel was investigated by UV-vis spectrophotometry full-wavelength scanning. Besides, a quantification method was developed by high performance liquid chromatography (HPLC), and then validated by measuring the encapsulation efficacy of larotaxel liposomes. RESULTS: The four spectral characteristics of larotaxel were revealed and the corresponding standard spectra were defined. It was confirmed that larotaxel had the structure of tricyclic diterpenoids, with the molecular formula of C45H53NO14, the molecular weight of 831.900 1, and the maximum absorption wavelength of 230 nm. The quantitative method of larotaxel was established by using HPLC with a reversed phase C18 column (5 μm, 250 mm×4.6 mm), a mobile phase of acetonitrile-water (75:25, volume/volume), and a detection wavelength of 230 nm. The validation study exhibited that the established HPLC method was stable, and had a high recovery and precision in the quantitative measurement of larotaxel in liposomes. In addition, a new kind of larotaxel liposomes was also successfully prepared. The particle size of the liposomes was about 105 nm, with an even size distribution. And the encapsulation efficiency of larotaxel in the liposomes was above 80%. CONCLUSION The present study offers reference standard spectra of larotaxel, including MS, IR, NMR, and UV-vis, and confirms the molecular formula, molecular weight and chemical structure of larotaxel. Besides, the study develops a rapid HPLC method for quality control of larotaxel liposomes.
