4 weeks of arrested embryos.The AAH expression was found to have the similar result as HIF-1?'s.Conclusions The expression level of HIF-1? and AAH in villi of missed abortion patients is much lower than that of normal early pregnant women.HIF-1? and AAH have a function of supporting normal pregnancy,so their low expression may be an important cause of missed abortion.
4. Short-term therapeutic effects of combined therapy with metformin hydrochloride for aplastic anemia
Medical Journal of Chinese People's Liberation Army 2012;37(3):218-222
Objective To screen and select new drugs for aplastic anemia (AA) and evaluate their clinical efficacy by clinical bioinformatics methods. Methods First, we established genome expression profiles of AA patients, and conducted similarity analyses with the pharmacogenomics database to screen and select drugs with possible efficacy. Intractable AA patients who received immunosuppressors and/or androgen for more than six months showing no clinical efficacy were enrolled in the study to evaluate therapeutic effects of the therapeutic regime. Clinical efficacy and adverse effects were evaluated after six months. Results he clinical bioinformatics results showed therapeutic effects of metformin hydrochloride on AA. Forty-three intractable AA patients (15 with severe AA) were treated with metformin hydrochloride combined with cyclosporin A (CsA) and stanozolol. Twenty-seven transfusion-dependent patients (100%) became transfusion independent after a 6-month therapy. The hemoglobin level completely returned to normal in 37 out of 40 anemia patients (92.5%). In the 40 patients with platelet count lower than 20×109/L, the platelet count of 28 patients (90.3%) increased to higher than 50×109/L. The white cell count increased to higher than 3.5×109/L in 30 out of 35 patients (88.6%) with white cell count lower than 2.5×109/L. Among 40 anemic patients, 1 was found to have abnormal renal function, but it recovered to the normal range after ending CsA treatment. Eighteen patients were found to have elevated transaminase levels which were lowered to normal range after using liver protectants and reducing the dosage of stanozolol. There were no instances of hypoglycemia in all patients throughout the treatment. Conclusion Combination of metformin hydrochloride, CsA and stanozolol is effective in refractory aplastic anemia with acceptable toxicity.

Objective To understand of work status and professional ability of ICU specialist nurse,test their specialist ability level,improve and enhance the specialist nurse management to maximize their roles in promoting the development of clinical nursing.Methods 38 ICU nurse specialists who have got the nursing credentials more than one year were surveyed through self-questionnaire about working conditions,including general conditions,work status,income,self-assessment of specialist ability in future.Results 100% ICU trained the younger nurses,and discuss the nursing management and problems.36.8% nurses participated clinical nursing and night shift,5.3% nurses have never joined ward inspection.Rates of reaching the standard were higher and above the 90% in those three aspects: practice in clinical work,guided teaching and providing information for family member.Grasp of academic knowledge (86.8%),theory teaching (86.8%) and providing academic knowledge for nursing (86.8%) needed to be improved.Paper searching and reading (65.8%),paper writing (57.9%) and research design (47.4%) were relatively lower.Conclusions Culturing and using the specialist nurses in ICU lack the program and rationality; Specialist nurses have vague role; talent team was lacked; pay status needs increased; research ability needed enhanced; admittance,training and using criteria were lacked.

In this study, 31 Notopterygium incisum populations were analyzed using ITS sequences to investigate the genetic structure. The results showed that: the ITS region ranged in size from 634 to 635 bp and base composition was with high G + C content of 57.8%. Thirty-one polymorphic sites were detected from 402 sequences of 31 populations of N. incisum, and the proportion of polymorphic sites was 4.88%, in which parsimony informative sites were up to 12. And 31 haplotypes were identified based on these polymorphic sites. Molecular variance analysis (AMOVA) indicated that high genetic differentiation (57%) existed among population, and gene flow was low (N(m) = 0.38) among populations. Phylogenetic relationships of 31 haplotypes were analyzed using NJ method with N. forbesiias an out-group. Phylogenetic analysis showed that 31 haplotypes from different populations mixed together and did not form distinct geographically separated clades.

The ideal treatment and recovery of osteoarticular injury remain to be resolved. Small intestinal submucosa (SIS), a naturally-occurring decellularized extracellular matrix, has been recognized as an ideal scaffold for tissue engineering and widely used in repairing various tissues and organs. Nowadays its application has also been gradually increased in the field of orthopedics. We reviewed laboratorial studies and clinical trails about the application of SIS in bone and joint repair, aiming to evaluate its effects on the repair of bone, cartilage, meniscus, ligament and tendon. SIS has showed promising results in repairing bone, meniscus, ligament or tendon. However, additional studies will be required to further evaluate its effects on articular cartilage and tendon-bone healing. How to optimize SIS material,is also a focused problem concerned with making SIS a potential therapeutic option with high value for orthopedic tissue repair.

A 48-year-old man presented with a 4-day history of fever and 10-year history of papulovesicles on the face, neck, trunk and limbs which had been aggravated 10 days prior to the presentation.Skin biopsy showed a dermal infiltration of numerous small- to medium-sized atypical lymphocytes, which was mainly located around blood vessels or appendages, with the involvement of subcutaneous fat tissue and destruction of blood vessels. The infiltrating atypical cells stained positive for CD45RO, CD8, CD56, T-cell intracellular antigen-1, granzyme B, Epstein-Barr virus-encoded small nuclear RNAs (EBER), but negative for CD20, CD79a, CD3, CD4 or CD30. Cytoplasmic CD3ε was also observed in these cells. Laboratory examinations on admission revealed a progressive decrease in peripheral erythrocytes, white cells and platelets, persistent increase in serum aminotransferase and bilirubin, and decline in serum fibrinogen and hypertriglyceridemia. The B-mode ultrasound of the abdomen showed hepatosplenomegaly. Based on the above findings,the diagnosis was made as extranodal nasal type NK/T-cell lymphoma of skin complicated by hemophagocytic syndrome.

Objective:Studying changes of chemical constituents of Cinnamomum cassia after compatibility in Coptis chinensis;determining the amount of cinnamic acid in the decoction.Method:An YWG C18 column was used with a mobile phase of CH3CN-0.01%H3PO4(27∶73),the flow rate was 1.0 ml*min-1 and the detection wavelength was 280 nm.Result and Conclusion:The calibration curve of cinnamic acid had good linear relationship in the range of 0.112~4.48 μg.The average recovery was 100.0%, the relative standard deviation was 0.66%. The amount of cinnamic acid was decreased in the decoction, and the decreased degree was related with the ratio of C. chinensis to C. cassia.

The objectives of study was to investigate the clinical characteristics and risk factors of pure red cell aplasia (PRCA) following ABO-incompatible allogeneic hematopoietic stem cell transplantation (allo-HSCT). The clinical data of 72 patients receiving ABO-incompatible allo-HSCT were collected and retrospectively studied. The clinical parameters including sex, age, granulocyte engraftment time and blood transfusion were analyzed for the exploration of risk factors resulting in development of PRCA. The results indicated that 4 out of 72 patients receiving ABO-incompatible allogeneic hematopoietic stem cell transplantation developed PRCA, 3 cases out of these patients were ABO-major incompatible, 1 case was Bi-direction incompatible, nor any effect of PRCA was observed on incidence of GVHD and CMV infection. In conclusion, PRCA is a major complication of patients receiving ABO-incompatible allo-HSCT, while ABO blood group of O/A in recipient/donor pair may be the major high risk factor for PRCA after ABO-mismatched allo-HSCT.
