Objective To observe the clinical efficacy of triple needling at myofascial trigger points plus warm needling in treating periarthritis of shoulder. Method Eighty patients with periarthritis of shoulder were randomized into a treatment group of 44 cases and a control group of 40 cases. The treatment group was intervened by triple needling at myofascial trigger points plus warm needling, while the control group was by warm needling alone. The two groups were treated once a day, 10 times as a treatment course. The Pain Rating Index (PRI), Visual Analogue Scale (VAS), Present Pain Intensity (PPI), and motion of shoulder joint were observed before the treatment and after 2 treatment courses, and the clinical efficacies were compared between the two groups.Result In the treatment group, the PRI, VAS, and PPI scores respectively after 1 and 2 treatment courses were significantly different from those before the treatment (P<0.05,P<0.01). In the control group, the scores after 2 treatment courses were significantly different from those before the treatment (P<0.05). After 2 treatment courses, the scores in the treatment group were significantly different from those in the control group (P<0.01). In both groups, the motions of shoulder joint respectively after 1 and 2 treatment courses were significantly changed compared with those before the treatment (P<0.01). The motions of shoulder joint in the treatment group were significantly different from those in the control group respectively after 1 and 2 treatment courses (P<0.05,P<0.01). The recovery plus markedly-effective rate and total effective rate were respectively 70.5% and 95.5% in the treatment group, versus 52.5% and 90.0% in the control group, and the between-group differences were statistically significant (P<0.01,P<0.05).Conclusion Triple needling at myofascial trigger points plus warm needling is an effective approach in treating periarthritis of shoulder.

AIMTo explore the effects of cholesterol rich diet on the activities of blood coagulative and fibrinolytic systems in male rabbits.

METHODS14 male New Zealand white rabbits were randomized to cholesterol rich diet(CRD) group and common diet (control) group. Rabbits in CRD group were fed with 1% cholesterol embedded diet and those in the control group were fed with common diet. Levels of blood TG, TC, LDL, HDL, Lp(a), apoA1, apoB, FIB, D-dimers and FDP, PT and APTT, activity of ADP, AT-III, PLG and alpha2-PI were tested in all rabbits before given cholesterol rich diet and after 12 weeks' feeding with different kinds of diet.

RESULTSLevels of blood TG, TC, LDL, HDL, Lp(a), apoA1, apoB, FIB, D-dimers in CRD group were all elevated significantly compared with those in the control group and the baseline levels. PT and APTT were shortened, ADP, PLG and alpha2-PI activity were increased in CRD group.

CONCLUSIONCholesterol rich diet not only is the direct cause of hyperlipidemia but also can increase the coagulative activity and inhibit the fibrinolytic activity and promoting the evolution of arteriosclerosis.

Objective To compare clinical outcome of intracytoplasmic sperm injection(ICSI)cycle by using fresh and cryopreserved-thawed testicular and epididymal spermatozoa in azoospermic patients.Methods Between September 2006 and May 2007,208 azoospermic patients underwent in vitro fertilization(IVF)were treated in Center of Reproductive Medicine,Peking University Third Hospital.Those couples were divided into two groups based on their wishes,including 171 cases in fresh group and 37 cases in cryopreserved-thawed group.The cryopreserved testicular or epididymal spermatozoa were thawed and recovered before ICSI procedure iu thawed group.The outcomes of ICSI in each group were compared.including clinical outcomes(two pronuclear fertilization,high quality embryo,clinical pregnancy and embryo implantation)and pregnancy outcomes(spontaneous miscarriage,gestational weeks and neonatal birth weight).Results (1),The utilization rate were 92%(23/25)in cryopreserved-thawed testicular spermatozoa and 100%(12/12)in epididymal spermatozoa.(2)Between fresh and cryopreserved-thawed groups,no statistical difference was observed in two pronuclear fertilization rate[62.25%(973/1563)vs.64.53%(282/437),P=0.960],high quality embryo rate[78.9%(768/973)vs.79.1%(223/282),P=0.985],clinical pregnancy rate per embryo transfer[44.4%(60/135)vs.46.9%(15/32),P:0.688]and embryo implantation rate[29.3%(84/287)vs.33.3%(23/69),P=0.508].(3)No significant difference between flesh and cryopreserved group was found in spontaneous miscarriage rate (11%vs.7%,P＝1.000),gestational weeks(single birth:39.0 weeks vs.38.7 weeks,P:0.538;twins:36.8 weeks vs.36.3 weeks,P=0.571)and birth weight(single birth:3409 g vs.3350 g,P=0.699;twins:2584 g vs.2635 g,P=0.703).Conclusion It suggested that tissue from the azoospermic patients who underwent diagnostic testieular and epididymal biopsy should be eryopreseved for IVF-ET.

Objective To explore the effects and mechanism of bexarotene in combination with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on apoptosis of leukemic cell line KG1a. Methods KG1a cells at logarithmic growth phase were obtained, and were divided into TRAIL group, bexarotene group, 300 ng/mL TRAIL in combination with bexarotene group and 2.0 μmol/L bexaroten in combination with TRAIL group. Cell apoptosis rate was detected in each group by flow cytometry. Flow cytometry was also employed to determine the apoptosis rates of KG1a cells after treatment with bexarotene and TRAIL in different sequences. The expression of Fas associated death domain-like IL-1 beta converting enzyme inhibitory protein (c-FLIP) was detected by Western blotting. Results There was no significant difference in cell apoptosis rates between TRAIL group and bexarotene group of each concentration (except for bexarotene 2.0 μmol/L) (P > 0.05). The cell apoptosis rates of 300 ng/mL TRAIL in combination with bexarotene group and 2.0 μmol/L bexaroten in combination with TRAIL group were significantly higher than those in TRAIL group and bexarotene group of each corresponding concentration (P <0.01). Sequential analysis revealed that bexarotene could reverse the resistance of KG1a cells to TRAIL (P < 0.001). Compared with single use of 2.0 μmol/L bexarotene or 300 ng/mL TRAIL, combination use could significantly down-regulated the expression of c-FLIP (P < 0.05). Conclusion Bexarotene can significantly enhance the apoptosis of KG1a cells induced by TRAIL, which may be attributed to the down-regulation of c-FLIP expression.

Objective To explore the relationship between the diabetic retinopathy (DR) and the carotid artery intima-media thickness(IMT) in type 2 diabetic patients to reveal the relationship between macroangiopathy and microangiopathy in diabetic patients further. Methods One hundred and tweenty-three diabetic cases in patient chosen from 2008 to 2009 were divided into diabetic retinopathy group(DR) and non-diabetic retinopathy group(NDR) by fundus examination. The patients were asked about their disease history including durations, smoking and so on. Meanwhile the carotid artery IMT, systolic pressure (SBP), diastolic pressure (DBP), serum total cholesterol, triglycerides, high density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol, glycosylated hemoglobin(HbAlc), body mass index(BMI) were measured of all the cases. The incidence of increased carotid artery IMT was cmpared with χ2 test, as well as the average IMT between the two groups, the influencing factors artery IMT was 50.98%(26/51) in DR group, and 33.33%(24/72) in NDR group, having a statistically significant showed the diabetic retinopathy risk factors were smoking(χ2=6.20, P<0.05), duration(t=-4.13, P<0.01). carotid artery IMT(t=-2.21, P<0.05), SBP(t=-2.37, P<0.05), and HDL-cholesterol(t=4.49, all P<0.01). 12.77, all P<0.01), carotid artery 1MT and smoking(χ2=6.05,4.15, all P<0.05). Conclusions Type 2 diabetic patients complicated with DR have a prominent increase in IMT thickening proportion and average IMT, which reveals the relationship between the DR and the IMT.

Bone marrow mesenchymal stem cells (MSCs), multipotent stem cells, can replicate as undifferentiated cells and have the potential to differentiate into different lineages of mesenchymal tissues, including bone, cartilage,endothelial, neural, smooth muscle, skeletal myoblasts, and cardiac myocyte cells. The ischemia-induced death of cardiomyocytes results in scar formation and reduced contractility of the ventricle. Several preclinical and clinical studies have supported the notion that MSCs therapy may be used for cardiac regeneration.When transplanted into the infracted heart, MSCs prevent deleterious remodeling and improve recovery, but the mechanism is not clear. In this work,we review evidence and new prospects that support the use of MSCs in cardiomyoplasty.
