Objective To study the treatment effect of rivet with thread,instead of clavicular hook plate,for Tossy Ⅱ & Ⅲ dislocation of acromioclavicular joint.Methods From January 2008 to February 2009,totally 31 patients with Tossy Ⅱ or Ⅲ dislocation of acromioclavicular joint were treated using rivets with thread,including 19 males and 12 females at the age of 33-49 years(mean,41 years).Among these patients,19 suffered fresh acromioclavicular joint dislocation,9 suffered old acromioclavicular joint dislocation,and 3 did a failed fixation by clavicular hook plate.None of them was combined fracture.Mitek 3.0 mm rivet with thread was embedded to coracoid,with nonabsorbable thread connected with the rivet passing through the clavicle for fixation,and meanwhile ligament coracoclaviculare was restored or acromiocoracoid ligament displaced.Among them,12 patients assisted Kieschner wire fixation.The treatment effect was evaluated using Japanese Orthopaedic Association(JOA)scoring system and acromioclavicular joint dislocation scoring system.Results All patients were followed up 11-23 months(mean,17 months).In the patients without Kieschner wire fixation,JOA shoulder score was 65-95,excellent for 8 cases,good for 9,fine for 1,poor for 1,excellent and good rate was 89.47%(17/19);In the patients with Kieschner wire assisted fixation,JOA shoulder score was 74-97,excellent for 5,good for 4,fine for 3; the excellent and good rate was 75.00%(9/12).With acromioclavicular joint dislocation scoring system,the overall excellent and good rate was 94.74%(18/19),and 91.67%(11/12)respectively.No complication that affected joint function was found.Conclusion Rivets with thread can be used for treating Tossy Ⅱ & Ⅲ dislocation of acromioclavicular joint.This surgical technique is characterized by small operation wound,fewer complications,no secondary operation,and satisfactory treatment effect.

Objective To investigate the relationship between body mass index(BMI) and the outcomes of liver function of patients with hepatocarcinoma after surgery. Methods We divided the patients into three groups: normal, overweight and obese groups based on BMI, then we recorded their preoperative and the postoperative liver functions: albumin, total bilirubin, alanine aminotrasferase(ALT), aspertate aminotransferase (AST), alkaline phosphatase(ALP), γ-glutamyltranoferase(γ-GGT), triglycerides(TG), total cholesterol (TC), high density lipoprotein(HDL) and low density lipoprotein(LDL). Results The mean values of ALT change between the preoperative and the postoperative were (14.9 ± 1.98) U/L, (15.4 ± 2.27) U/L,(22.2±1.32) U/L; Mean values of γ-GGT change were(16.2 ± 1.33) U/L, (18.7 ±0. 97) U/L,(22.3 ± 1.27) U/L; mean values of TG change were (0. 18 ± 0. 44) mg/dL, (0. 21 ± 0.08) mg/dL,(0.25 ± 0.03) mg/dL. Compared with the results of control groups, there were no significant differences of recovery of liver functions between normal and overweight groups(P ＞ 0. 05), but the obese group' s recovery of liver functions did lag behind the normal group (P ＜ 0.05). It is showed that the obese group' s shared same recovery of albumin, total bilirubin, AST, ALP, TC, HDL and LDL. The difference was significant between the normal and obese groups in terms of recovery of ALT, γ-GGT, TG(P ＜ 0. 05). Conclusion BMI is associated with the recovery of liver function of patients with hepatocarcinoma, the obese patients have poor prognosis of recovery of liver function.

OBJECTIVE:To observe the effects of Xingnaojing injection on the efficacy and safety of patients with acute cere-bral infarction merge blood stasis syndrome. METHODS:70 patients with acute cerebral infarction merge blood stasis syndrome were randomly divided into observation group(35 cases)and control group(35 cases). Control group received conventional treat-ment according to 2014 edition of Chinese guideline for diagnosis and management of acute ischemic stooke. Patients within throm-bolysis time window were given intravenaus infusion of rt-PA,and those out of thrombolysis time window orally received 0.3 g As-pirin tablet every evening,then 0.1 g after 1 week+40 mg Atorvastatin calcium tablet every evening,and if patients have arfficulty suallowing,gavage administiation was implemented. Observation group additionally received 30 ml Xingnaojing injection,adding in-to 250 ml 0.9% Sodium chloride injection,intravenous infusion,once a day. The treatment course for both groups was 14 d. Clini-cal efficacy,γ-interferon(IFN-γ),interleukin-13(IL-13),interleukin-4(IL-4),high-sensitivity C-reactive protein(hs-CRP)lev-els,the US National Institutes of Health Stroke Scale(NIHSS)rating,improved Barthel index(BI),infarction size before and af-ter treatment and the incidence of adverse reactions in 2 groups were observed. RESULTS:There was no significant difference in the total effective rate and incidence of adverse reactions in 2 groups(P>0.05). Before treatment,there were no significant differ-ences in IFN-γ,IL-13,IL-4,hs-CRP levels,the NIHSS rating,BI and infarction size in 2 groups(P>0.05). After treatment,the IFN-γ,hs-CRP levels,the NIHSS rating and infarction size in 2 groups were significantly lower than before,and observation group was lower than control group,IL-13,IL-4 and BI were significantly higher than before,and observation group was higher than control group,the differences were statistically significant (P<0.05 or P<0.01). CONCLUSIONS:Based on conventional treatment,Xingnaojing injection shows obvious efficacy the efficacy and safety of patients with acute cerebral infarction merge blood stasis syndrome,it can reduce the levels of inflammatory cytokines,improve neurological deficits,daily living skills and in-farct volume,with good safety.

With the aggravation of population aging and the change of social convention,especially after the introduction of two-children policy,some families wish to have two children can not be achieved due to various reasons.Therefore,they use assisted reproductive technology to achieve fertility aspirations.Surrogate is a controversial topic in the assisted reproductive technology,the contradictions between the normal reproductive rights of the infertile woman and the women who have lost their children but passed the age of childbearing and the bad ethical consequences and rights disputes of surrogacy.How to avoid the bad ethical consequences and meet the demand of reasonable surrogate is the major issue worthy to be discussed.

Objective To study the awareness and behaviors for patients′ privacy protection among undergraduate nurses. Method By using questionnaire, the survey was conducted among 100 undergraduate nurses. Results The score on the awareness and behaviors for patients′privacy protection was (15.84 ± 1.25). There were significant differences in the awareness and behaviors among different internship time, gender and hospitals (all P<0.05). Conclusions Awareness and behaviors for patients′privacy protection among undergraduate nurses are at a medium level. It is a demand to enhance the education on patients′privacy protection , especially to male undergraduate nurses and at the beginning of internship so as to prevent the patient-nurse disputes.

All of them were estimated by the Fragmented Picture Naming Task. Results The patient group had lower priming scores than the young (t=5.558, P<0.001), and middle and elderly-aged (t=3.100, P=0.003) control group in the Fragmented Picture Naming Task. Conclusion Perceptual priming is not only concerned with occipital lobe, but also with frontal and temporal lobes possibly.

ObjectiveTo compare the appearance of abnormal lipid accumulation in skeletal muscle fibers in various neuromuscular disorders by analyzing the results of Oil-Red-O staining of muscle biopsy samples. Methods523 muscle biopsies performed in 1998—2002,consisted of lipid storage myopathy, mitochondrial diseases, inflammatory myopathy, muscular dystrophy, steroid myopathy, alcoholic myopathy and neurogenic muscle atrophy,were studed. ResultsType Ⅰ fibers were selectively involved in lipid storage of muscle fibers.In all diseases, men were more frequently affected than momen in which men to women was 3∶2.Marked uniformity lipid storage in muscle fibers was found most frequently in patients with lipid storage myopathy and mitochondrien-lipid-glycogene storage diseases. Moderate uniformity lipid storage in the muscle fibers was found in patients with steroid myopathy, alcoholic myopathy and malnutrition. Moderate or marked non-uniformity lipid storage in muscle fibers was found in patients with mitochondrial cytopathy, inflammatory myopathy, muscular dystrophy. Moderate non-uniformity lipid storage in muscle fibers was found in patients with neurogenic muscle atrophy. Mild lipid storage in muscle fibers was found in numerous systemic disease and neuromuscular disorders. ConclusionNumerous neuromuscular diseases can associated with abnormal lipid metabolism in muscle fibers, in which the men are more involved than women. The appearance of lipid accumulation in the muscle fibers markedly changes in different neuromuscular diseases. The diagnostic value of lipid storage in muscle fibers should be considered under analysis clinical symptoms and other myopathological findings.

Objective To investigate the role of depression and C-reaction protein (CRP)in the early development of vascular disease in the elderly patients with type 2 diabetes. Methods Totally 396 patients with type 2 diabetes were recruited in the study,including 196 cases with depression and 200 cases without depression.Depression was evaluated by Hamilton depression scale (HAMD),and CRP was measured using rate nephelometry.The related parameters of wave intensity (WI) such as accelerating wave intensity (W1),decelerating wave intensity (W2),arterial stiffness β,pressure-strain elasticity modulus (Ep),arterial compliance (AC),pulse wave velocity -wave intensity(PWVWI),pulse wave velocity (PWV) and argumentation index (AI) were detected and compared between the groups. Results The levels of CRP [(8.1±2.8)mg/L vs. (3.9±3.2) mg/L,t=6.411,P=0.000],W2 [(4.82±1.33) mm Hg· m-1 · s-3 vs.(2.27±1.28)mm Hg · m-1 · s-3,t=4.256,P=0.021],arterial stiffness β(12.58±3.23 vs.8.96±2.24,t=4.634,P=0.019),Ep (157.90±52.64 vs.118.24±53.08,t=5.512,P=0.007),PWVβ(7.53± 1.41 vs.6.68±1.56,t=3.982,P=0.024),AI(19.26± 13.21 vs.15.34±10.23,t=3.213,P=0.037)and PWV-WI (7.59±1.67vs.6.63± 1.45,t =2.613,P =0.046) in cases with depression were higher than the cases without depression,while the AC value was reduced (0.70±0.19 vs.0.78±0.21,t=4.676,P =0.017).There was no difference in W1 value between the groups.The CRP level and HAMD score were positively associated with W2 (r=0.470,P=0.000),stiffness β (r=0.582,P=0.000),Ep (r=0.352,P=0.004),PWV-WI (r=0.233,P=0.019),PWVβ (r=0.340,P=0.007) and AI (r=0.265,P=0.015),but negatively related with AC(r=-0.457,P=0.000).HAMD score was positively correlated with CRP level(r=0.328,P=0.003). Conclusions The carotid artery wave intensity W2,blood vessel elasticity parameter β,Ep,AC,PWV-WI,PWVβ and AI determination can evaluate the risk of cardiovascular diseases in elderly diabetes,and higher CRP level and HAMD score may deteriorate its process.

Objective: To establish the yeast expression system for oncostatin M (OSM). Methods:The cDNA encoding human OSM was inserted into pPIC9K vector and transformed into Pichia pastoris. The correct phenotype of recombinants was screened through MD and MM auxotrophic culture medium. The OSM mRNA transcription in the P.pastoris and molecular weight were identified with Northern blot and Western blot. MTT method was used to test the activity of OSM in inhibiting the growth of human melanoma cells. Results: Established P.pastoris system could accomplish human OSM secreting expression. The recombinant OSM with a 30 000 molecular weight amounted to 70% of the total protein in medium supernatant. The OSM showed an inhibitory effect on the growth of A375 cells in vitro. Conclusions：The P.pastoris system of OSM was proved effective with a high expressing level. The secreted recombinant OSM present in supernatant of culture medium would be easy to be purified. It may lay the foundation for the large-scale preparation of OSM in future.
