Objective To investigate the effect of 1,25-(OH)2D3 and salvia miltiorrhiza on T cell subsets and cytokines in rats after allogeneic bone marrow transplantation.Methods Female Wistar rats were used as recipients and male SD rats were used as donors.All Wistar rats were divided into aGVHD group and intervention groups at random,and the intervention groups were further divided into 1,25-(OH)2D3 group,salvia miltiorrhiza group and combination group.The changes of T cell subsets (CD4+ and CD8+) and cytokine (IL-2,IFN-?,IL-4 and IL-10) in every group were detected and measured.Results When the presentation of aGVHD was relatively conspicuous,CD4+ and CD8+ were increased,and the increase of CD4+ was predominant.Compared with the difference prior to transplantation,the difference was statistically significant (P

Objective To follow-up the patients with successful posterior segment intraocular foreign body removal.Methods Medical records of consecutive cases with posterior segment intraocular foreign body that were successfully removed between June 2005 and June 2008 were retrospectively reviewed.Twenty-three patients(23 eyes)were included in the series.Results Followed up 3-36 months All the patients underwent pars plana vitrectomy for posterior segment intraocular foreign body removsl,4 patients (4 eyes)experienced rhegmatogenous retinal detachments that were managed with good long-term visual outcomes.Conclusions Rhegmatogenous retinal detachments may occur following successful removal of posterior segment intraocular foreign body in several months after initial management.These rhegmatogenous retinal detachments can be successfully managed with a variety of methods,depending upon the extent and location of the detachments and causative break.Therefore,it is clinically important to perform a long-term follow-up in patients after successful posterior segment intraocular foreign body removal.

Objective To investigate the relationship between apolipoprotein (Apo) e4 allele and endothelium dependent arterial dilation in females with type 2 diabetes mellitus. Methods One hundred and one female type 2 diabetic patients without angiopathy, aged 40 71 years, and 95 healthy female individuals were selected. PCR/allele specific oligonucleotide probes were used to determine Apo e genotypes, and high resolution ultrasound was applied to measure brachial artery flow mediated endothelium dependent dilation and glyceryltrinitrate (GNT) mediated endothelium independent dilation. Results (1) In both diabetic patients and healthy individuals, the flow mediated endothelium dependent arterial dilation in subjects with e4/3 or e4/4 genotypes was (3.22?0.29)% and (3.78?0.34)% respectively, which were significantly lower than those in subjects with e2/2 or e3/2 genotypes 〔(3.96?0.33)% and (4.74?0.41)%, P

In order to improve the metabolism yield of cordycepin and adenosine,we studied nitrogen sources ,the levels of nitrogen sources and carbon sources,dynamic development in liquid culture ,as well as the total yield of cordycepin and adenosine in culture system through determining the contents of cordycepin and adenosine by HPLC .The results are as follows: not only animal protein but also some plant protein is very good nitrogen sources; in culture solution the suitable levels of nitrogen sources and carbon sources is respectively 3% and 4%; the content of adenosine in culture solution is very low, while it is quite high in mycelia; it is much higher that the total yield of cordycepin in culture solution than in mycelia; when the culture system is oscillated and cultured after 7~9 days, the total yield of cordycepin and adenosine are both high.

Objective To investigate the regulation expression of leukemia inhibitory factor(LIF)in hu- man and animal osteoarthritic(OA)tissues and its clinical relevance.Methods 1)Thirty-five Japanese rabbits, aged eight months,were used to make models of experimental osteoarthritis.Operations were performed at the right knee and the sham ones at the left knee in each rabbit.Rabbits were sacrificed on the 3,7,14,28,42,56 and 84 days after operation respectively.Cartilage and synovium of the knee were collected to observe histological changes of osteoarthritis at different times;immunohistochemistry analysis was conducted to observe the LIF expression and distribution in the cartilage and synovium of the animals.2)From April 2003 to October 2003,32 samples of human articular tissues(cartilage,subchondral bone and synovium)were obtained in the operational procedures and a good quantity of RNA was isolated using Magnetic Beads.The patients who underwent articular operations donated the samples.In the reverse transcription-polymerase chain reaction(RT-PCR),the mRNA expression of LIF was mea- sured by semi-quantity analysis and the location of LIF protein was determined by enzyme-linked immunosorbent assay (ELISA).Results A slight expression of LIF was seen in normal cartilage but less in synovium.However,the expression of LIF was remarkable in synovial lining cells,superficial and middle layers of cartilage in animal os- teoarthritis.There was a significant difference in expression between the animal osteoarthritis and the control group (P＜0.05 ).In human tissue study,LIF mRNA was expressed to a very low level in normal articular tissues and there was no significant difference(P＞0.05)between different anatomical locations.In moderate degrading sub- chondral bone,LIF mRNA was expressed to its highest level.LIF was expressed to the highest level in seriously degrading cartilage tissues.The results were similar to ELISA testing results.LIF extents varied in different articular tissue sections.Conclusions LIF is an important mediator that can contribute to tbe pathogenesis of OA.The different temporal and spatial distributions of LIF in normal and OA tissues imply that LIF may play some important roles in pathogenesis of OA.

Objective To observe the histological effect of acellular dermal matrix(ADM)on insufficiency in guide keratinized tissue regeneration. Methods 6 cases of single anterior tooth implantation in the hospital in 2016 were included in the study. 3 cases were treated with immediate tooth extraction and implantation. Bone substitution materials were grafted in the space between the tooth extraction socket and the implants. The keratin-ized tissue dehiscence was covered by double layers of acellular dermal matrix membrane(Heal-All?,ZH-BIO, China),which was fixed to the adjacent soft tissue by suturing. Another 3 cases were routinely treated with delayed implantation of single anterior tooth. All the cases were subject to harvesting of the cover soft tissues of implants with a punch 4 months later. The new grown soft tissues were histologically observed. Results All cases were sur-vived. The new grown keratinized tissues were observed. Conclusion Acellular dermal matrix can guide the aug-mentation of keratinized tissues.

BACKGROUND: Uncontrolled-rate freezing in -80 ℃ refrigerator is convenient, while controlled-rate freezing in -196 ℃ liquid nitrogen is reliable and long-term, the combination of the two can simplify the process and has been successfully used in clinics. OBJECTIVE: To explore the influences of different cryoprotectants by ladder-style freezing from -80 ℃ low temperature refrigerator to liquid nitrogen on the cryopreservation of hemopoietic stem cells. METHODS: The experiments were divided into four groups: 10% dimethyl sulfoxide (DMSO) group, 5% DMSO combined with 3% hydroxyethyl starch group, 5% DMSO combined with 0.25 mol/L trehalose group, 5% DMSO combined with 3% hydroxyethyl starch and 0.25 mol/L trehalose group. Peripheral hemopoietic stem cells were cryopreserved by ladder-style freezing from -80 ℃ low temperature refrigerator to liquid nitrogen. The ultrastructural changes were examined by transmission electron microscopy, the expressions of Annexin-V, PI and Caspase-3 were detected by flow cytometry. RESULTS AND CONCLUSION: There was no significant difference in survival rate, apoptotic rate and necrotic rates of the cryopreserved cells in the four groups (P > 0.05). The ultrastructural changes had no significant difference under the transmission electron microscopy. The viability was more than 90% in frozen-thawed mononuclear cell colonies, and the apoptosis was roughly 50% in the frozen-thawed CD45+ cell population, which contained many mature cells. Of hemopoietic stem cells, early stage cells have greater resistance to damage of cryopreservation than late stage cells. It is concluded that the addition of hydroxyethyl starch or trehalose into DMSO exhibits no synergistic protective effect on the cryopreservation of hemopoietic stem cells.
