Objective To investigate simple manual humeroulnar distraction for alleviating elbow stiffness due to upper limb fracture. Methods Twenty-seven patients with elbow stiffness due to upper limb fracture were divided into control and experimental groups. Before treatment there was no significant difference in stiffness between the groups. The controls were treated with the combined mobilizations and passive stretching. The experimental group was treated with manual humeroulnar distraction alone. Both groups were treated for four weeks. Range of motion ( ROM) and the Mayo elbow function scale (MEFS) were used to evaluate elbow function before and after 4 weeks of treatment. Results After 4 weeks, there was a significant difference between the groups. In the experimental group average ROM reached (110±20) °,an average of 29.6°better than the controls (80.4±23.6) °. MEFS scores also showed significant differences between the experimental group (93. 85±7. 95) and the control group (83.93±9. 24). Conclusions Humeroulnar joint distraction might increase ROM and improve the functioning of stiff elbow joints. This finding may help rehabilitation professionals choose more effective manual mobilization techniques for treating elbow stiffness after upper limb fracture.

Objective To study the influence of aging and chemotherapeutic drugs of breast cancer patients on chemotherapy-induced amenorrhea (CIA) and to guide the further selection of drugs for chemotherapy.Methods We prospectively studied the CIA of the premenopausal breast cancer patients and compared the difference in CIA between the patients who were at different aging periods or received different chemotherapeutics. Results 137 patients were followed up.The occurrence rate of CIA and long-term chemotherapy-induced amenorrhea(LCIA)were 73.72%(101/137)and 43.80%(60/137)respectively.The rate of CIA and LCIA was significandy higher in older women(＞40 years)than young women(≤40 years,X2=25.32,18.42,P＜0.05).The recovery rate of CIA in young women was 61.90%(13/21)which was significantly higher than the older women[35.00%(28/80);X2=4.99,P=0.025].The difference in the rate of LCIA was statistically significant between the older women (＞40 years)who received different anthracyclinebased chemotherapy(X2=6.92,P=0.031).Conclusion Age is an important factor for the CIA.Chemotherapy has less influence on the menstruation of younger women(≤40) and most amenorrhea is reversible.For older women,the rate of LCIA is different in patients who receive imported epirubicin,domestic epirubicin or pirarubicin.

The majority of women diagnosed with early-stage breast-cancer have an excellent long-term prognosis, but many still suffer from worsened life quality and infertility caused by chemotherapy-induced amenorrhea(CIA). The risk of CIA varies by patient age, but is not significantly influenced by chemotherapeutic regimens. CIA will improve disease-free survival and overall survival for patients with hormonal receptor positive tumors. For low-risk patients and patients with the intention of maintaining fertility, proper treatments need to be chosen to preserve their reproductive function.

BACKGROUND: The problem to be solved firstly in adipocyte implantatior after its in vitro adherent ulture f preadipocyte with scaffold using tissue-engineered technique is the biocompatibility of scaffold and dipocyte.OBJECTIVE: To investigate the feasibility of poly-β-hydroxybutyric acid (PHB) used for readipocyte implantation.DESIGN: Randomized controlled trial.SETTING: Medical College of Wuhan University.MATERIALS: This trial was carried out in Medical College, Wuhan University during October 2003 o June 2005. Twelve male SD rats(Experimental Animal Center, Medical College, Wuhan University), weighing rom 200 to 250 g, were involved.PHB scaffold was provided by Institute of Polymer Materials, Department f hemical Engineering, Tsinghua University.METHODS: The preadipocytes of rats were isolated, purified and ultured in vitro for use. PHB scaffold was made into 0.75 cm×0.75 cm ×0.2 cm lamellar cell biological caffold, then which were soaked by DMEM/F12 culture medium containing 150 g/L fetal bovine serum and laced in culture plate, one piece each well, 12 wells totally. 1.0 mL cultured cell suspension was added n each well to prepare cell scaffold complex. Eight rats were selected. The prepared complexes were implanted into right-side back tissue of a rat and fixed with 5-0 silk, serving as adipocyte scaffold roup; the biological scaffolds without adipocyte adherence were implanted into left-side back tissue of he same rat with the same method, serving as blank scaffold group. One lamellar biological scaffold was mplanted into each side. Eight weeks later, the appearance and structural change of grafts were observed, nd the grafts were weighted and their volumes were measured. Four lamellar biological scaffolds were mplanted into the other 4 rats separately and taken out after 3 weeks, then they were fixed by 100 g/L eutral formalin, sliced, and stained by haematoxylin and eosin (HE). Their histological changes were observed.MAIN OUTCOME MEASURES: ① Gross and histological observation of grafts in adipocyte scaffold roup and blank scaffold group. ② Comparison of volume and mass of grafts in two groups.RESULTS: Twelve ets were involved in the result analysis ,without deletion. ①Gross observation: In the adipocyte scaffold group, grafts presented flesh-color appearance and peplos in the peripheral region, and newly ormed minute blood vessels ingrowing into the scaffold. In the blank scaffold group, grafts presented rey ppearance, which was coated by peplos. ② HE staining: Three weeks later, a few scattered adipocytes were ound in the peripheral region of the grafts,there were very few vessels. Eight weeks later, lamellar ibrous peplos was found around the complex. Adipocytes ingrew from the peripheral region of scaffold into caffold, partial scaffold was nearly full of adipocytes and many vessels formed;In the blank scaffold roup, only peplos and vessels were found, scaffold was full of fibrous connective tissue and adipocytes ere not found. ③ Comparison of volume and mass: adipocyte scaffold group was superior to blank group in scaffold volume and mass [(257.5±70.2)vs.(144.6±62.6)mm3,(245.6±58.2) vs.(148.7±60.3)mg, both P＜0.01].CONCLUSION: Preadipocyte can adhere to PHB scaffold, proliferate and differentiate into mature dipocytes. It is feasible for PHB material to serve as a carrier for preadipocyte.

MicroRNAs (miRNAs) are small endogenous non-coding RNA molecules.They regulate negatively the expression of target genes at post-transcriptional stages by means of affecting the stability of target mRNA or interfering with the transcriptional process.Recently,there is evidence demonstrating that miRNAs play important roles in the gene expressions of thyrotoxic heart diseases.Elevated levels of thyroid hormones profoundly influence the cardiovascular system through the renin-angiotensin system (RAS).As a principal active component of RAS,angiotensin Ⅱ receptor 1 (AT1 R) interacts with miRNAs in promoting or extenuating the progress of thyrotoxic heart disease.In this article,the roles of AT1R-associated miRNAs,miR-21,miR-155,miR-208a/b,and miR-499 in thyrotoxic heart disease were reviewed.

0.05).But it showed significant higher level in moderate and severe PIH patients than the normal ones. (prepartum. 1195?72、1206?96 vs 1102?89, intrapartum, 1256?81、1308?84 vs 1174?86). The concentration of IECa 2+ has positive relationship with MAP in PIH patients. Conclusions The best method to decrease the harmfulness of overload IECa 2+ is to normalize its level by effective measure of decrease the blood pressure.
