Methods Twenty-four EM patients were enrolled and the expression of E-cadherin and ?-catenin in endometrial and endometriotic tissues were determined by immunohistochemistry method. Normal endometrial tissue from 21 individuals was included as the control group. Results Compared with the control group, in E-cadherin and ?-catenin expression was shown in no difference between the secretory and the proliferative phase of endometrial tissue from EM patients. Furthermore, the expressions of E-cadherin and ?-catenin in normal endometrial tissue were stronger than that of EM patients(P

Objective To explore the differentiation potency of ES cell-derived epidermal stem cells compounded by dermal analogs reconstructed with bone MSCs in hypodermis.Methods The dermal analogs were reconstructed with rat bone MSCs and compound gel-gelatin sponge.E14-ES cells,labeled with Hoechst 33342,were cocultured with human amnion.Four days later,epidermal stem cell clones were formed.The skin analogs,reconstructed with ES cell-derived epidermal stem cells and dermal analogs,were transplanted into 129 mice hypodermis.The differentiation tissue of skin analogs was sampled at 2,4,6,8 weeks.The sections were observed with HE staining,immunohistochemical and di-labeled immunofluorescence methods to test the expression of ?1 integrin,CK15,CK19,CEA,CK18.Results The sections were showed tubular or follicular like structures formed with simple or stratified epithelium at 2 and 4 weeks.Keratinized stratified squamous epithelium,sweat glands-like,sebaceous glands-like and hair follicles-like structures were observed at 6 week and 8 week after transplantation.The cells labeled by Hoechst 33342,formed tubular or follicular like structures,expressed?1 integrin,CK15,CK19,CEA and CK18positive respectively at 2 and 4 weeks.The sweat glands-like structure expressed CEA and CK18 positive respectively at 6 and 8 weeks.There were more sebaceous glands-like structures.Conclusion ES cell-derived epidermal stem cells compounded by dermal analogs reconstructed with bone MSCs can differentiate into keratinized stratified squamous epithelium,sweat glands-like,sebaceous glands-like and hair follicles-like structures in hypodermis.

Objective To determine and compare the daily cost of various ophthalmic solutions for glaucoma in China. Design Investigative study. Participants The majority ophthalmic solutions for glaucoma available in our country were included in the research. Methods Five bottles of each solution were tested separately by five researchers. After the number of drops and the actual volume for each bottle were calculated, the mean number of drops per bottle and the mean volume per bottle were determined. The volume per drop was calculated by dividing the mean volume per bottle by the mean number of drops per bottle, and the cost per drop was calculated by dividing the market price by the mean number of drops in a bottle. The number of days for both eyes usage per bottle was calculated by dividing the mean number of drops in a bottle by the number of drops required daily for both eyes. The cost per day was calculated by multiplying the cost per drop by the number of drops required daily for both eyes. Main Outcome Measures The number of days for both eyes usage per bottle and the daily cost: for both eyes usage per bottle. Results 1. The volume per drop ranged from 0.027 ml(Lumigan) to 0.053 ml(Chengrui and 0.5%Zhenrui). 2. The cost per bottle ranged from 5.7Yuan(Malaisuan Saimaluo'er) to 338Yuan (Xalatan). 3. The number of days for both eyes usage per bottle ranged from 52d (Lumigan) to 12d ( Zhenrui). 4. The daily cost for both eyes usage from expensive to cheap were Xalatan 7.51Yuan, Travatan 6.30 Yuan, Lumigan 3.84 Yuan, Alphagan 3.36 Yuan, Dilijian 2.97 Yuan, Pailiming 2.83 Yuan, 2%Zhenrui 2.34 Yuan, Betagan 2.11 Yuan, Beiteshu 2.0 Yuan, 0.5% Zhenrui 1.49 Yuan, 2%Huming 1.29 Yuan, Mikelan 1.21 Yuan,1%Huming 0.85 Yuan, Chengrui 0.63 Yuan, Malaisuan Saimaluo'er 0.23 Yuan. Conclusions The daily cost of ophthalmic solution for glaucoma ranged wildly. These data may be useful in selecting ophthalmic solution for glaucoma therapy.

Objective Exploration of best effect on washing medical instrument between automatic cleaning sterilizer and ultrasonic cleaners.Methods Suppose washing method A and method B.A:directly put medical instrument into automatic cleaning sterilizer,wash,sterilize and dry it step by step.B:place medical instrument into ultrasonic cleaners,wash with ultra sonic,shower with cool water,sterilize and dry with hot water.Results By comparison,after washing method A,there remains 0.33‰ residue on the medical instrument while after B there are 0.03‰ remains.It has an evident difference between result of the two methods(?~2=46.546,P=0.000).Especially on the cleaning result of saw-shaped medical instrument:A method has 0.52‰ residue while method B is 0.04‰,which is of great significance.But there exists no significant difference of washing result on non saw-shaped instrument(?~2=2.667,P=0.102).Conclusion Ultrasonic cleaners can reach the optimum washing effect on saw-shaped medical instrument,with a great decline on residue after cleaning.And automatic cleaning sterilizer can wash large quantity of non saw-shaped,saving labor and enhancing efficiency by automation cleaning process.Therefore,adpoting different equipment to wash different instrument can efficiently improve cleaning effect and ensure safe and qualified stelization.

Objective To study the role of bone turnover markers in multiple myeloma(MM)bone disease.Methods Thirty-eight MM patients were studied.Serum and urine samples were taken before,after 3 months and 6 months therapy.Serum samples of tartrate resistant acid phosphatage isoform-5b(sTRACP-5b),bonespesific alkaline phosphatase(sBAP),osteocslcin(sOC),urine samples of N-telopeptides of type Ⅰ collagen(NTX)were measured.Results Urine NTX concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in pleateum patients and controls.serum TRACP-5b concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in controls.There were no statistical significance compared with pleateum patients.Serum BAP concentrations were significantly lower than that in pleateum patients and controls.Serum OC concentrations were not statistically significant among the newly diagnosed patients,relapsed or refractory patients,pleateum patients and control.In newly diagnosed patients.urine NTX levels were significantly higher in stage Ⅲ than that in stage Ⅰ/Ⅱ,serum BAP levels were significantly lower in stage Ⅲ than that in stage Ⅰ/Ⅱ.There was a positive relationship between urine NTX and serum TRACP-5b in newly diagnosed patients.Urine NTX levels were significantly decreased,and serum BAP levels were significantly increased after 3 cycles effective therapy.There was no change in serum TRACP-5b and OC.Urine NTX and serum TRACP-5b were significantly diseased,serum BAP and OC were significantly increased after 6 cycles of effective therapy.But bone lesions on X-ray did not diminish at that time.Conclusion There is a closely relationship between bone turnover markers and bone lesions in MM.The bone turnover markers may be useful in monitoring MM progress and therapy.

Objective To evaluate the safety of myomectomy by extrusion in cesarean section , in comparison with routine cesarean delivery. Methods From January 2008 to December 2010, a total of 128 operations of myomectomy by extrusion in cesarean section were performed (Myoma Group), while another group of 128 cases undergoing caesarean section , which respectively followed every cases of the Myoma Group but had no hysteromyoma , was selected as the control group .The amount and rate of postpartum hemorrhage , the level of postpartum fever , and postoperative hospital stay between the two groups were compared , respectively. Results In the two groups:the amount of postpartum hemorrhage was (233.6 ±58.9) ml vs.(228.5 ±90.9) ml (t=0.530, P=0.597); the rate of postpartum hemorrhage was 0% (0/128) vs.0.8% (1/128) (P=1.000); the decrease of haemoglobin was (6.17 ±2.83) g/L vs.(6.89 ±3.09) g/L (t=-1.944, P=0.053); the decrease of hematocrit was 2.22%± 0.98%vs.2.27%±1.02% (t=-0.400, P=0.690); the rate of postpartum fever was 2.3% (3/128) vs.5.5% (7/128) (χ2 =1.665, P=0.197);the length of postoperative hospital stay was (4.2 ±0.8) d vs.(4.1 ±1.2) d (t=0.706, P=0.481). There were no significant differences between the two groups in the abovementioned parameters . Conclusions The myomectomy by extrusion in cesarean section does not increase the level of postpartum hemorrhage and the rate of postpartum infections .It is a simple, minimally invasive , safe and feasible surgical method , being worthy of clinical application .

MicroRNA (miRNA) is a class of endogenous,single-stranded non-coding small RNA that contains 21 to 23 nucleotides and is widely distributed in eucaryon,miRNA plays an important regulatory role in cell proliferation,apoptosis,growth and development through the regulation of gene translation after transcription and expression,miRNA has a close relationship with pathogenesis and development of hepatocellular carcinoma.And in this process,part of miRNA acts as oncogenes or tumor suppressor genes.A number of miRNA,such as miR-30d,miR-221,miR-222 and miR-101,had been found to express abnormally in hepatoeellular carcinoma.Here we summarize the related progress in research of miRNA and hepatocellular carcinoma.
