Heterotopic ossification is a pathologic bone formation,and can lead to joint dysfunction.There are several related factors for heterotopic ossification,such as surgery and wound,cytokine,genetic factor and perioperative drugs,while the definite pathogenesis is still unclear.Mature heterotopic ossified bone shows similar images as normal bones,and dynamic histomorphologic measurements suggest contrast to normal bone,heterotopic ossified bone exhibits higher metabolic activity.Risk factors for heterotopic ossification include severe central nerve injury,long-term coma,limb spasticity,limb braking and increase of serum alkaline phosphatase.Related factors for heterotopic ossification at molecular level are important in future studies to provide support for the prevention and therapy in heterotopic ossification following trauma or surgery.

Methods 62 patients in department of urinary surgery from June 2009 to October 2011 were selected as research object,and they were randomly divided into the control group and the observation group with 31 cases in each group,the two groups adopted routine nursing mode and evidence-based nursing mode respectively.Then the nursing requirement and nursing effect before and three and five days after nursing were compared between two groups. Results All the patients existed needs of related knowledge guidance,unhealthy emotion adjustment and social support,and the needs of patients between ureter external drainage and inner stent drainage showed no significant differences,improvement level of each items of the observation group after nursing were all better than those of the control group. Conclusions The patients with ureter external drainage or inner stent drainage have needs of related knowledge guidance,unhealthy emotion adjustment and social support,and the evidence-based nursing mode can effectively improve the patients'demand situations of these items.

Objective To discuss factors influencing the heterotopic ossifications (HO) after treatment of bi-column acetabular fractures. Methods One hundred and ninety-three cases of bi-column acetabular fractures were followed up, including 147 males and 46 females with an average age of 34. 4 years. Thirty-one cases were associated with craniocerebral trauma. The interval between injury and surgery was less than 1 week in 15 cases, 1 to 2 weeks in 121 cases, 2 to 3 weeks in 34 cases, and over 3 weeks in 23 cases. Factors that might have influenced HO, including surgical method, associated injury, and interval between injury and surgery, were analyzed retrospectively. Results All the cases were followed up for an average of 44. 2 (14 to 84) months. The mean operation time was 238 (150 to 330) minutes, and the average blood loss was 1453 (450 to 4400) mL. The incidence rate of HO was 39. 9% (77 in 193 cases), including 39 cases of degree one, 23 cases of degree two, and 15 cases of degree three. Of the 77 cases associated with HO, 14 had craniocerebral trauma and 63 did not (χ~2 = 0. 019, P = 0. 891) . HO was found in 2 cases that had been operated on in less than 1 week, 38 cases in 1 to 2 weeks, 21 cases in 2 to 3 weeks, and 16 cases in over 3 weeks. The Spearman correlation analysis between HO degree and clinical result showed no correlation ( R = 0. 041, P =0. 722). Only 15 cases (7. 8% ) were associated with HO after the debridement of the necrotic gluteus minimus. Conclusions HO after surgery for bi-column acetabular fractures may not be correlated with craniocerebral trauma, but highly correlated with the interval between injury and surgery. Debridement of necrotic gluteus minimus and other muscles can reduce the incidence of HO.

ObjectiveTo explore the effect of left move and twists of I/t curve on predicting prognosis of facial paralysis.Methods181 cases with 171 Bell's palsy and 10 Hunt's syndrome were examined with I/t curve of frontal muscle and upper orbicularis. The assessing criterion of diseases course was determined according to the recovery time of frontal muscle evaluated by raising eyebrow, the recovery time of orbicularis ascertained by House-Brackmann Ⅰ, Ⅱ grades and stable phase in partial moderate and severe facial paralysis.ResultsThe recovery time of frontal muscle and orbicularis between twist and non-twist in I/t curve and in sex was not significant. The left move of I/t curve was confined to slight, moderate and severe arranges; the recovery time was not significant also. Twist rate in I/t curve was highest in moderate facial paralysis and then second in orbicularis of slight paralysis. The left move of I/t curve had a very significant relationship with recovery time of frontal muscle and orbicualris.ConclusionThe left move of I/t curve plays a very important role in determining nerve injury degrees and predicting prognosis of facial paralysis.

Objective To observe the effect of dihydromyricetin of ampelopsis grossedentata on lipid metabolism and antioxidation in atherosclerosis (AS) rats. Methods Sixty Wistar rats were randomly divided into five groups (n = 12 each):normal control group, model control group, positive control group, high dose dihydromyricetin group (40 mg·kg-1 ) and low dose dihydromyricetin group (10 mg·kg-1 ). Except normal control group, rats in the other groups were injected with a single dose of vitamin D3(600 000 U·kg-1 ) and loaded with high fat diet to establish AS model. Simvastatin (5 mg·kg-1 ) was intragastrically administered to positive control group. High and low dose dihydromyricetin groups received intragastric administration of 40 and 10 mg·kg-1 dihydromyricetin, respectively. Equal volume of purified water was given to normal and model group. After 24 weeks of administration, serum levels of lipids, activities of superoxide-dismutase (SOD) and malonicdialdehyde (MAD) were determined. Results As compared with model control group, triglycerides (TG) of high and low dose dihydromyricetin groups was decreased [(191. 65±101. 10) vs. (111. 10±29. 29) and (120. 55±38. 12) mg·L-1 , respectively], total cholesterol (TC) was decreased [(151. 64±33. 62) vs. (148. 49±30. 14) and (118. 90±27. 38) mg·L-1 ], and high density lipoprotein cholesterol (HDL-C) was increased [(1. 29±0. 68) vs. (2. 10±0. 70) and (1. 62±0. 61) mmol·L-1 ], low density lipoprotein cholesterol (LDL-C) was decreased [(5. 01±1. 33) vs. (3. 97±0. 78) and (4. 28±0. 79) mmol·L-1 ], activity of SOD was increased [(141. 03±42. 52) vs. (187. 97±42. 08) and (150. 99±46. 17) U·mL-1 ], and MDA was decreased [(20. 51±3. 81) vs. (17. 64±1. 54) and (18. 52± 3. 42) nmol·mL-1 ], with significant differences (P<0. 05, P<0. 01). Conclusion Dihydromyricetin can reduce the level of serum lipid, improve antioxidation activity, and has therapeutic effect for atherosclerosis.

To clone Uroplakin Ⅱ gene from Chinese transitional cell carcinoma (TCC) of bladder and construct its eukaryotic expression vector, the molecular cloning method was used to extract total RNA from a GⅢ/ T3N0M0 tissue sample of the bladder TCC patients. The primers were designed by Primer 5.0 software. Full length cDNA of Uroplakin Ⅱ gene was amplified by reverse transcription polymerase chain reaction (RT-PCR), assayed by nucleic acid sequencing and then inserted between Xba Ⅰ and HindⅢ restrictive sites of eukaryotic expression vector pcDNA3.0. The recombinant was assayed by restricted enzyme digestion. Under the induction of Lipofectamine 2000, the recombinant was transfected into Uroplakin Ⅱ negative bladder cancer cell line EJ. Cellular expression levels of Uroplakin Ⅱ were detected by RT-PCR. The nucleic acid sequencing results indicated that Chinese Uroplakin Ⅱ cDNA (555 bp) was successfully cloned. The BLAST analysis demonstrated that the cloned sequence is 100 % homologous with sequences reported overseas. The GenBank accession number AY455312 was also registered. The results of restricted enzyme digestion indicated that eukaryotic vector pcDNA-UP Ⅱ for Uroplakin Ⅱ was successfully constructed.After being transferred with pcDNA-UPⅡ for 72 h, cellular Uroplakin Ⅱ mRNA levels were significantly improved (P＜0.01). It is concluded that human Uroplakin Ⅱ gene was successfully cloned from Chinese TCC tissues, which provided a basis for further exploration of the roles of Uroplakin Ⅱ gene in TCC biological behaviors and potential strategies for targeted biological therapy of TCC.
