OBJECTIVETo investigate the therapeutic effects of manipulative reduction for calcaneal fractures.

METHODSFrom January 2009 to June 2012, 53 cases (60 affected feet) of Sanders type I-IV calcaneal fractures were treated by manipulative reduction and external fixation with cardboard splint,including 45 males and 8 females with an average age of (33.5 +/- 1.54) years old ranging from 18 to 65. The course of disease ranged 0.5 h to 7 d. Before treatment the feet were swelling, ache and activity limitation in evidence, some feet were wide flat deformity, the cortical bone was broken in the imaging examination. All selected cases were evaluated using Creighton-Nebraska health foundation assessment scale for fractures of calcaneus.

RESULTSAll cases were followed up at 12 months after treatment, 13 feet got excellent curative effect, 34 good, 11 moderate and 2 poor.

CONCLUSIONManipulative reduction for Sanders type I-IV calcaneal fractures could get excellent curative effect. Manipulative reduction for calcaneal fractures could avoid surgical trauma while assure high curative effects. Manipulative reduction is not only economical and easy therapy, but also can restore maximum function of the calcaneus with few complications and facilitate early rehabilitation of ankle and joint function.

BACKGROUND:Transforming growth factor-βhas been shown to exert an obvious induction effect on the differentiation of bone marrow mesenchymal stem cells into chondrocytes. Cyclical tensile strain simulates mechanical environment of chondrocytes in the body, and plays an important regulatory role in cellproliferation and differentiation. OBJECTIVE:To discuss the synergy of transforming growth factor-βand cyclical tensile strain in inducing the differentiation of bone marrow mesenchymal stem cells into chondrocyte-like cells. METHODS:A total of 10 2-month-old New Zealand rabbits were selected. Bone needle was used to penetrate the medul ary cavity of bone. 3.0-4.0 mL of bone marrow was extracted for isolation and culture of bone marrow mesenchymal stem cells. Passage 3 cells were randomly assigned to four groups:blank, transforming growth factor-β, cyclical tensile strain and cyclical tensile strain+transforming growth factor-βgroups. After 1, 3 and 6 days, cells were obtained. General morphology was observed using safranin O staining. Glycosaminoglycan levels were detected by alcian blue staining. Matrix metal oproteinase-13 and tissue inhibitor of metal oproteinase-1 levels in supernatant were measured using ELISA. Type II col agen, matrix metal oproteinase-13 and tissue inhibitor of metal oproteinase-1 mRNA relative expression was detected using RT-PCR. RESULTS AND CONCLUSION:Safranin O staining showed fusiform or irregular triangular cells. cellnumber
and matrix secretion increased in each experimental group than in blank group. Glycosaminoglycan levels in the supernatant were greater in the transforming growth factor-βand cyclical tensile strain+transforming growth factor-βgroups than in the blank group (P<0.05). Type II col agen mRNA relative expression was higher in the cyclical tensile strain+transforming growth factor-βgroup than in the blank group (P<0.05). Results indicated that transforming growth factor-βand cyclical tensile strain could induce the differentiation of bone marrow mesenchymal stem cells into chondrocytes, showing an apparent cooperative action.

A 36-year-old woman presented with a 3-year history of pruritic erythema and scaling on the trunk and extremities.Dermatological examination revealed ill-defined light pink macules with white lamellar scales on the chest,abdomen and buttocks.Histologically,there was a focal mononuclear cell infiltrate in the superficial dermis,with the epidermotropism of some cells and mild atypia of epidermotropic cells,as well as an interstitial mononuclear cell infiltrate and mild deposition of mucin between the collagen fibers in the middle dermis.CD3 and CD4 were expressed by scattered mononuclear cells infiltrating the upper and middle dermis.Based on these data,the patient was diagnosed with interstitial granuloma fungoides.

Objective To investigate the efficacy of ventral bladder mucosa onlay graft urethroplasty for the management of panurethral stricture.Methods From August of 2005 to July of 2013,11 cases of panurethral stricture were treated by ventral bladder mucosa onlay graft urethroplasty.The median age of the patients was 53 years (22-72 year),The median stricture length was 15 cm (12-18 cm).The patient was placed in the lithotomy position,Penile urethra was exposed by circumcoronal incision and degloving of skin,Bulbar urethra was exposed by inverted Y-shaped perineal incision.The strictured urethral segment was then opened ventrally in the midline up to at least 1 cm proximally into the healthy urethra.An appropriate size bladder mucosa graft was harvested,and was quilted to the splited urethra edge,the graft width was 1.5-2.0 cm.Two F10 fenestrated silicone catheters were left as urethral stents,a suprapupic cystostomy tube was left.The urethral stent was removed 4 weeks postoperatively.Follow-up was performed every 3 months for the first year,and annually thereafter.Success was defined as normal voiding with a maximum flow rates ≥ 15 ml/s,and the patients required no further instrumentation,including dilation or urethrotomy.Results The mean follow-up was 18 months (range,9-36 months),the overall success rate was 10/11.One patient developed urethral meatus stenosis 3 months postoperatively,and was managed by meatal dilatation.Conclusion Ventral bladder mucosa onlay graft urethroplasty can be used for the management of panurethral stricture,Bladder mucosa is an alternative substitution for complex urethral reconstruction.

OBJECTIVETo observe the effect of six common Chinese medicinal herbs for promoting blood circulation, including Radix Paeoniae rubra (I), Radix Salviae miltiorrhizae (II), Rhizoma Chuanxiong (III), Radix Notoginseng (IV), Semen Persicae (V) and wine steamed Radix et Rhizoma Rhei (VI), on blood lipids and inflammatory reaction of atherosclerotic plaques in ApoE gene deficiency mice.

METHODSNinety mice, 6 - 8 weeks old, were divided into 8 groups, the model group, the control group (treated with simvastatin) and the six treated groups treated with the above-mentioned 6 Chinese medicinal herbs respectively. All the mice were fed with the diet of western kind for 13 weeks until the mature atherosclerotic plaques formed in them. Then they were treated with respective drugs for another 13 weeks except those in the model group. All the mice were sacrificed at the end of experiment, their blood was collected for lipids determination, heart and aorta were taken out for determining the level of CD68 in root of aorta, as well as the expressions of monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-a (TNF-a) by immunohistochemistry staining.

RESULTSAll the 6 Chinese herbs showed regulatory action on blood lipids. The positive expression of CD68 in the model group displayed the highest activity. As compared with the model group, the CD68 positive expressed cells in the control group and the groups treated with Chinese herbs II, III, and IV were lesser (P < 0.05), and the expression of inflammatory factors (MCP-1 and TNF-alpha) in atherosclerotic plaques was significantly lower in the control group and the group treated with Chinese herb VI (P < 0.05).

CONCLUSIONChinese medicinal herbs tested in this study can interfere the maturing progress of atherosclerotic plaques and stabilize the plaques in ApoE deficiency mice, the mechanisms may relate to its actions in regulating lipids metabolism and inhibiting inflammatory reaction. Different Chinese medicinal herbs for activating blood circulation of conventional dosage might show difference in potency and acting links.
