Objective To explore the relationship of personality and coping style between parents and male inpatients with internet addiction disorder. Methods 51 male inpatients with internet addiction disorder and their parents were investigated with Cattell 16PF and Coping Style Questionnaire to evaluate their personality and coping style. All data were analyzed by partial correlate analysis. Results Multi-factors of 16PF( warmth, reasoning, emotional stability, dominance, vigilance, sensitivity, abstractedness, privateness, openness to change, perfectionism, apprehension, tension ) of male inpatients were significantly correlated with father' s ( r = 0.72 ～ 0. 85 or - 0. 71 ～ - 0.93 ) or mother' s 16PF( r = 0.73 ～ 0.92 or - 0. 72 ～ - 0.81 ), bu+ non of those factors corrected with the same factor of parental. Male inpatients' coping style did not corrected with father' s, but their problem sloving, rationalization and self-accusation corrected with mother's seeking support, rationalization and avoidance respectively. Conclusion The personality of male inpatients with internet addiction disorder is affected by parental personality, but under the impact of internet addiction disorder, this kind of influence is weakened. In coping style, the father' s influence is far weaker than the mother' s, suggesting that there is father function flaw during the process of those inpatients growing up.

OBJECTIVE:To provide reference for rational use of human serum albumin for surgical inpatients. METHODS:The utilization of human serum albumin for surgical inpatients in a hospital during Jan.-Mar. 2014 was analyzed and evaluated by UHC Guidelines for the Use of Album,Nonprotein Colloid,and Crystalloid Solutions(2010 edition)and European Immune Globu-lin and Albumin Use Recommendation. RESULTS:Among the 556 patients,totally 895 human serum albumin application were con-ducted,mainly involving development of gastrointestinal surgery(29.7%),hepatobiliary surgery(25.9%)and cardiothoracic sur-gery(13.1%). The main reasons were correcting hypoalbuminemia(62.9%),followed by albumin supplemented during major sur-gery(7.9%)and alleviating ascites in patients with cirrhosis(4.4%);only 95 applications(10.6%)were considered appropriate. The most prevalent inappropriate reason was for correcting hypoalbuminemia. CONCLUSIONS:Human serum albumin in the surgi-cal inpatients in the hospital shows a large amount,and low consistent rate between indications and guidelines. The rational stan-dardized utilization of human serum albumin should be strengthened.

Objective To explore the relationship between osteoporosis knowledge and activities and fear of falling of elderly in the community.Method 420 elders in community were investigated with osteoporosis knowledge assessment tool (OKAT) and the modified survey of activities and fear of falling in the elderly (MSAFFE).Result The overall average score of MSAFFE was (25.36±4.58),and exercise capacity dimension scored higher (13.89±2.41).The overall average score of OKAT was (9.11±3.81).The correlation coefficient of MSAFFE and OKAT was-0.11～ 0.58(P＜0.05).The level of knowledge osteoporosis could explain 24％,18％,16％ variation of activities and fear of falling in each dimension.Conclusion The level of knowledge osteoporosis in the elderly is closely related to activity and fear of falling.Health education should be strengthened to improve the life quality of older people.

Objective To screen cardiac-specific short-acting peptides on live myocardial slices using phage display technology,so as to improve the targeted delivery efficiency of drugs in myocardium and provide effective candidates for the targeted therapy of Duchenne muscular dystrophy (DMD) and other cardiomyopathies.Methods Myocardial tissue slices were prepared and cultured in vitro.The protein activities of the tissues were examined by immunohistochemistry.The in vitro cultured myocardial tissue slices were co-incubated with phage library (1×1012 pfu),and the phages that bound to the myocardium were recovered and amplified.The cardiac-specific targeting phages were identified by five rounds of in vitro phage biopanning.The candidate phage-related insertion sequence was sequenced,and the in vivo tissue distribution of the highly enriched phages was verified.Results A platform for in vitro culturing of live myocardial slices was established.Myocardial slices with good biological activity were obtained.After 48 hours of culturing,the normal expression and localization of Dystrophin protein were detected.Using phage library,candidate phages were screened after five rounds of phage biopanning.The results of the sequencing analyses and in vivo tissue distribution verification indicated that the selected candidate phages showed significant enrichment in myocardium and skeletal muscle,and showed low levels in liver and kidney tissues.Conclusions The candidate phages showed higher binding efficiency in both myocardium and skeletal muscle,indicating that the candidate peptides had myocardial targeting property,and that can provide a new method for myocardial targeting therapy of DMD.

OBJECTIVETo compare the tissue engineered cartilage constructed with chondrocytes derived from auricular and articular cartilage.

METHODSChondrocytes were isolated from porcine auricular and articular cartilage, and BMSCs were obtained from bone marrow aspirate and cultured. Each kind of chondrocytes were resuspended alone or mixed with BMSCs at a ratio of 1:1, and seeded onto PGA/PLA scaffolds to construct tissue engineered cartilage (n = 4). The constructs were cultured for 8 weeks in vitro and then subcutaneously implanted into nude mice for 6 weeks. The differences between chondrocytes monoculture from articular and auricular cartilage or between each of them co-cultured with BMSCs were evaluated by gross view, measurement of thickness and wet weight, histological examinations including H&E, Safranin O, type II collagen, and Ponceau's & Victoria blue staining, and gene expression analysis of cartilage related genes.

RESULTSNo obvious differences were found histologically among the complexes constructed in vitro 8 weeks except for few elastic fibers secreted in the auricular chondrocytes + BMSCs co-culture group. Neo-cartilage is thicker in the groups of articular chondrocytes (38. 1% than the group of auricular chondrocytes, P < 0.05) and articular chondrocytes + BMSCs co-culture (19.3% than the group of auricular chondrocytes + BMSCs, P < 0.05). However, after 6 weeks in vivo the elastic fibers were found positive in the complexes constructed by auricular chondrocytes, and its staining was even stronger and more homogenous in the group of auricular chondrocytes + BMSCs co-culture. The tissues generated by articular chondrocytes alone and co-cultured with BMSCs both formed the characteristic features of three-layer structure of hyaline cartilage and ossified in vivo with significant up-regulation of COL10A1 and MMP-13. To summarize, auricular chondrocytes formed the elastic cartilage while articular chondrocytes formed the hyaline cartilage during the development of tissue engineered cartilage either by monoculture or the co-culture with BMSCs.

CONCLUSIONSThe chondrogenic response of chondrocytes from different cartilage origins demonstrates that an initial chondrocyte and cartilage type recapitulates the same in later tissue-engineered development.

OBJECTIVETo observe the clinical effect of Guilu Erxian Glue Cataplasm (GEGC) on carcinoma of the large intestine patients with myelosuppression after chemotherapy, and further to confirm its efficiency and safety.

METHODSTotally 60 patients with carcinoma of the large intestine were randomly assigned to two groups. Meanwhile, they all accepted FOLFIRI chemotherapy. Patients in the treatment group were additionally applied at Shenque (RN8), exchanging once per every other day, for 14 successive days. Patients in the control group took placebos with the same dose and dosage as the treatment group. The blood cell counts (WBC, NE, and PLT) were detected before chemotherapy, at day 7, 10, and 14. The TCM symptoms integrals, Karnofsky performance score (KPS), liver and kidney functions were observed before chemotherapy, at day 7 and day 14. Adverse skin reactions were observed each day. And the usage of hematopoietic growth factors was recorded.

RESULTS(1) The KPS score at day 7 was more stable in the treatment group than in the control group; the WBC and NE counts in the peripheral blood at day 14 were higher in the treatment group than in the control group; and TCM symptoms integrals at day 14 was lower in the treatment group than in the control group, all with statistical difference (P < 0.05). (2) Compared with the control group, the PLT count was higher in the treatment group than in the control group, the usage of rhG-CSF and antibiotics was less in the treatment group than in the control group, all with no statistical difference (P > 0.05). (3) No obvious adverse reactions such as liver injury, renal injury, or skin allergy were observed.

CONCLUSIONSAdjuvant treatment of GEGC could improve carcinoma of the large intestine patients with myelosuppression to some extent. No relevant adverse reactions were found.

OBJECTIVETo investigate the dental arch discrepancy in UCLP patients and the characteristics of orthodontic treatment of this kind of patients.

METHODS48 Unilateral cleft lip and palate patients were examined clinically and dental arch transverse discrepancy were recorded. Treatment plan was made according to the maloccusion of each patient.

RESULTS(1). Dental arch transverse discrepancy was seen in 60.4%, bilateral posterior crossbite in 33.3%, and unilateral posterior crossbite in 16.7% of patients with UCLP, respectively. (2). Serious crossbite was often seen in bicuspid region, so expansion in this area is the main task of orthodontic treatment. (3). Dental arch transverse discrepancy was usually mild in molar region. The upper molars were moved palatally in 10.4% of patients with UCLP.

CONCLUSIONSUpper arch expansion is often needed in patients with UCLP, and the potential of dental arch expansion was large. The decision of upper tooth extraction in patients with moderate crowding should be made after dental arch expansion. Dental arch expansion should be done before alveolar bone grafting. Prolonged usage of the retainer is often needed.

Objective To study the protective mechanism of astragaloside on skin photoaging. Methods BALB/c mice were randomly divided into four groups: model group irradiated with ultraviolet rays (UV), model plus matrix group pretreated with the matrix before UV irradiation, model plus astragaloside group pretreated with astragaloside 0.08% cream before UV irradiation, normal control group received no irradiation or pretreatment. After 4-week irradiation, the mice were sacrificed, and skin tissues were resected from the back of these mice. Then, reverse transeription PCR (RT-PCR) and immunohistochemistry were performed to detect the mRNA and protein expression of TGF-βR Ⅱ and Smad 7, respectively. Gray scale ratio was used to represent the mRNA levels of TGF-βR Ⅱ and Smad 7. Results There was a significant difference in the mRNA level (F = 80.98, 736.80, respectively, both P < 0.01) and protein positivity rate (F = 45.36,132.25, respectively,both P < 0.01) of TGF-βR Ⅱ and Smad 7 among the 4 groups. The mRNA level and protein positivity rate of TGF-βR Ⅱwere 0.2588±0.0283 and (28.20 ± 5.24)% respectively in the model group, significantly lower than those in the normal control group[0.5688 ± 0.0439, (53.00 ± 4.72)%, both P < 0.01] and model plus astragaloside group [0.3767 ± 0.0374, (41.64 ± 2.59)%, both P< 0.01]; on the contrary, the mRNA level and protein positivity rate of Smad 7 in the model group [0.8637 ± 0.0514, (82.06 ± 2.18)%] were significantly higher than those in the normal control group [0.5900 ± 0.0585, (47.50±3.81)%, both P < 0.01] and model plus astragaloside group [0.7131 ± 0.0410, (64.36 ± 2.62)%, both P< 0.01]. In the model plus astragaloside group, the mRNA level and protein positivity rate of TGF-βR Ⅱ were significantly higher than in the model plus matrix group [0.2653 ± 0.0456, (28.74 ± 2.28)%, both P < 0.01], while those of Smad 7 were statistically lower than in the model plus matrix group [0.8553 ± 0.0575, (82.62 ± 4.02)%, both P < 0.01]. However,no significant difference was observed in the mRNA level or protein positivity rate of TGF-βR Ⅱ or Smad 7 between the model group and model plus matrix group (all P > 0.01). Conclusion Astragaloside can prevent skin photoaging by the alteration of TGF-β pathway via up-regulating TGF-βR Ⅱ expression and down-regulating Smad 7 expression.

Objective To compare the incorporation method of 3H-TdR and 125Ⅰ-UdR on determining the proliferation effect of lymphocytes. Methods The proliferation effects of lymphocyte and Daudi lymphoma cells were estimated by 3H-TdR and 125Ⅰ-UdR incorporation. Results The incorporating fraction of 3H-TdR and 125Ⅰ-UdR into lymphocyte was 20.95% ± 1.06% and 1.00% ±0.04%,respectively, and the incorporating fraction for the lymphoma cells was 29. 94% ± 4. 10% and 6. 02% ±0. 73% ,respectively. The incorporation fractions of 3H-TdR into lymphocyte and lymphoma cells were much higher than those of 125Ⅰ-UdR, but the incorporating fractions of 3H-TdR or 125Ⅰ-UdR into the lymphoma cells were much higher than those of lymphocytes. Conclusions For lymphocytes, 125Ⅰ-UdR cannot substitute 3H-TdR as a tracer agent. But for lymphoma cells, whether 125Ⅰ-UdR could be replace 3H-TdR or not needs further research.
