Objective To explore the correlation between self-concept and subjective quality of life among children with tic disorders (TD). Methods The Piers-Harris Children's Self-concept Scale (PHCSS) and the Inventory of Subjective Life Quality (ISLQ) were complet-ed by 65 children with TD and 71 normal children from March to September, 2015; and analyzed with single factor analysis, correlation analysis and multi factors regression analysis. Results There was no significant difference in PHCSS scores between the TD children with and normal ones (t<1.624, P>0.05). The ISLQ scores of school life, self-awareness and cognitive component were less in the TD children than in the normal ones (t>2.051, P<0.05). The PHCSS subscores correlated with ISLQ subscores (P<0.05), except the following:PHCSS scores of behavior did not correlate with ISLQ scores of peer relationship, school life, living environment, self-awareness and cognitive com-ponent;PHCSS scores of intelligence and school environment did not correlate with ISLQ scores of family life, peer interaction and the liv-ing environment;PHCSS scores of physical appearance and properties did not correlate with ISLQ scores of family life and living environ-ment;PHCSS scores of anxiety did not correlate with ISLQ scores of family life, peer interaction and cognitive component;PHCSS scores of affiliation did not correlate with ISLQ scores of peer interaction;and PHCSS total score did not correlate with ISLQ scores of family life and living environment. PHCSS scores of affiliation were the factor related with the quality of life (β=0.301, P<0.05). Conclusion The quali-ty of life may be impaired in the children with TD, which may associate with the self-concept and need further intervention.

The clinicopathological data of 173 cases of inflammatory myofibroblastic tumor (IMT)were retrospectively analyzed.Among them 125 were males and 48 females with a mean age of 47.9 y (5-78 y).The lesions of 117 cases were located in lungs,41 cases in eyes,8 in ileocecum,2 in liver,2 in spleen,1 in abdominal wall,1 in maxillary sinus and 1 in face.The average diameter of lesions were 3.5 cm,ranging from 1.0 cm to 7.0 cm.The clinical manifestations were not specific,depending on the locations of tumor.The imaging examinations were helpful for diagnosis.The prcsence of slender-spindled myofibroblasts and proliferation of fibroblast cells,with infiltration of chronic inflammatory cells were the basic histopathological features of the disease.Combined with the histological characteristics and immunohistochemical staining IMT can be differentiated from other spindle cell tumors.Appropriate surgical resection is the main treatment for IMT.

AIM:To look for a way of produ cing mild therapeutic hypothermia through regulating transient re-ceptor potential cation channel subfamily V member 1 (TRPV1) pathway by dihydrocapsaicin (DHC).METHODS:Mice were subcutaneously injected with DHC at different doses (2 mg/kg, 3 mg/kg and 4 mg/kg) in order to find the best dose for reaching the target temperature (32~34℃).20%DMSO dissolved in normal saline was used as control group .After a single subcutaneous injection of DHC at an optimal dose was given , awaken CD1 mice were continuously infused with DHC at dose of 1 mg? kg-1? h-1 for providing a more rapid and stable temperature drop and duration of therapeutic mild hypothermia.The adult mice (9~10 weeks) and aged mice (24~27 months) were subcutaneously injected with DHC at the same dose, and the changes of the body temperature were monitored .RESULTS:DHC at 2 mg/kg resulted in a de-crease in the core temperature within the target therapeutic range (32~34 °C).After a bolus dose (2 mg/kg) was deliv-ered at 0 min followed by continuous infusion (1 mg? kg-1? h-1 ) beginning at 30 min, a rapid drop of body temperature to 34 ℃was achieved and the body temperature was maintained within the ranges of 32 to 34℃for the duration of the 6 h continuous infusion .DHC-mediated hypothermia did not lose its effectiveness in the adult and aged models .CONCLU-SION:DHC-induced activation of TRPV1 pathway produces mild therapeutic hypothermia .Besides, this method achieves stronger and longer center hypothermia and is suitable for the animals at different ages .

Objective To investigate the association between the apolipoprotein E (apoE) gene polymorphism and the dose for warfarin individual maintenance. Methods The genotypes of 249 patients with warfarin treatment in maintenance doses were determined by PCR/DHPLC assay. The doses for warfarin maintenance were compared among patients with different genotypes. Results In the total of 249 patients, the frequencies of 2/ε2, ε2/ε3, ε2/ε4, ε3/ε3, ε3/ε4, ε4/ε4 genotype were 1.20%, 15.66%, 1.80%, 72.29%, 9.24%, 0.80%, respectively; the allele frequencies of ε2, ε3, ε4 were 9.44%, 84.74%, 5.82%, respectively. The warfarin dose of group ε2 (ε2/ε2, ε2/ε3) was (3.24±1.36) mg/d, slightly higher than that of group ε3 (ε3/ε3, 2.91±1.14 mg/d) or group ε4 [ε4/ε4, ε3/ε4, (2.98±1.05) mg/d], but the difference of the warfarin doses among the 3 groups did not reach statistical significance (F=1.848,P＞0.05). Conclusion ApoE polymorphism may be not a major genetic factor that influences the individual dose for warfarin maintenance.

Objective To study the effects of curcumin mediated photodynamic therapy (PDT)on the growth and proliferation in human cervical cancer cell line H8 in vitro and in vivo,and to investigate its antitumor mechanisms.Methods The effects of curcumin mediated PDT on proliferation of human cervical cancer H8 cell by MTT assay was used to screen the optimal parameter.Changes in cell morphology were observed by May-Gr ünwald-Farbstoff Giemsa staining.The apoptosis rate was estimated by flow cytometry.The effect of PDT by curcumin on the expressions of Bcl-2,P53 and survivin in H8 cells was detected by fluorescence real-time reverse transcription-polymerase chain reaction (RT-PCR).Forty BALB/C nude mice underwent subcutaneous injection of H8 cell line so as to establish animal models,and then were randomly divided into four equal groups:control group,irradiation alone group,curcumin alone group,curcumin PDT group.HE staining and pathological examination were performed.Immunohistochemical study was conducted to detect the protein expression of the apoptosis inhibiting genes of Bcl-2.Results The proliferation inhibition of H8 cells was obvious after PDT when curcumin 5μmol/L with irradiation 100 J/cm2,and with dose dependent manner.Typical morphologic features of apoptosis appeared characterizedly by marked chromatin condensation,nuclear pyknosis and fragmentation,and the appearance of apoptotic bodies.The total apoptosis rate was higher in PDT group [(47.21 ± 4.11)％]than in control group(1.71 ±0.16) ％ (P＜0.01).The mRNA expression of Bcl-2,P53 and survivin in H8 cells were suppressed significantly.HE staining showed remarkable subcutaneous necrosis in the PDT group.Immunohistochemistry showed remarkable down-regulation of protein expression of Bcl-2(P＜0.01).Conclusions Curcumin-mediated photodynamic therapy has a significant killing effect on H8 cells in vivo and in vitro.Its antitumor effect might be related to induction of Tumor cell apoptosis and suppression of Bcl-2 mRNA and protein expression.

Objective To explore the mechanism of notch signaling pathway in the treatment of cervical cancer with notch receptor blocker(DAPT).Methods After treatment of Me180 cells with different concentrations of DAPT combined with curcumin-photodynamic therapy (PDT),3-(4,5 Dimethylthiazlo-yl)-2,5 Dimethylthiazol-2-yl)-2,5 dipheny tetrazo lium bromide(MTT)assay was used to detect the effect on the proliferation of Me180 cells,annexin V-FITC/PI combined with flow cytometry was used to detect the effect on apoptosis,and real-time fluorescence quantitative PCR and Western blot were used to detect the mRNA and protein expressions of Notch1 gene respectively.Results Both DAPT(1.0 μmol/L)and curcumin-PDT groups could inhibit the proliferation and induce apoptosis of cervical cancer cell line Me180,and the synergistic effect of the two groups was significant (P＜0.05 or＜0.01).DAPT and curcumin-PDT group reduced the mRNA expression level of Notch1 in cervical cancer Me180 cells with inhibition ratio of 40.0％ and 32.3％ respectively.DAPT and curcumin-PDT group inhibited the protein expressions of Notch1,nuclear factor-kappa B(NF-kB),vascular endothelial growth factor (VEGF),and the synergistic effect of the two groups was statistically significant.Conclusions Both DAPT and curcumin-PDT may effectively block the conduction of Notch signaling pathway,which is associated with down-regulation of the expression of Notch1 and NF-kappa B.Notch signaling pathway may be one of the targets of curcumin photodynamic therapy.

Objective To investigate the correlation between serum homocysteine (HCY) and chronic heart failure (CHF) hypercoagulable state in patients.Methods A total of 105 cases of patients with CHF was divided into three groups according to the New York Heart Association (NYHA) classification standard functions:heart functional grade Ⅱ group (42cases),cardiac function grade Ⅲ group (35 cases) and,NYHA class Ⅳ group (28cases).At the same time,40 healthy individuals were regard as the control group.HCY,fibrinogen (Fbg),D-dimer (DDI),HCY,N-terminal pro-brain natriuretic peptide (NT-proBNP) were detected by fasting venous blood samples which were collected within 24 hours after admission.Results Compared to the control group,the expression of Fbg,DDI,HCY and NT-proBNP increased,whereas,antithrombin Ⅲ (AT-Ⅲ) was reduced.Fbg,DDI,HCY,NT-proBNP,and AT-Ⅲ were found in all patient cases.Four groups were compared with each other,except for cardiac function Ⅱ group and the normal group had no significant difference between them (P ＞ 0.05),the difference between both other groups was significantly different (P ＜ 0.05),HCY had a positive correlation with Fbg,DDI,and NT-proBNP (r =0.268,0.295,and 0.404,P ＜ 0.05),and negative correlation with AT-Ⅲ (r =-0.240,P ＜ 0.05).Conclusions HCY might be a reliable indicator as a judge of CHF patients with hypercoagulable state,to detect HCY,FBG,DDI,and AT-Ⅲ in CHF patients.It benefits for judging thrombosis risk and determining the severity of the diseases.Anticoagulant therapy might be beneficial to reduce the long-term adverse events.

Objective To explore the influence of obstruction sleep apnea syndrome (OSAS) on plasma cystatin C (CC) levels in patients with primary hypertension.Methods A total of 244 cases of primary hypertension patients was chosen.The patients were divided into observation group (with OSAS) and control group (without OSAS) according to apnea hypopnea index (AHI).The observation group was then divided into three subgroups:mild OSAS group,moderate OSAS group,and severe OSAS group.The levels of CC were compared.Results First,the plasma CC levels in patients with primary hypertension had no statistical significance in the differences among different grades of hypertension (P ＞ 0.05).Second,CC levels of observation group were significantly higher than control group (P ＜ 0.05).Third,CC levels of the severe group were higher than the moderate group,and the plasma CC levels of the moderate group were also higher than the mild group and control group.Rank correlation analysis and comparison of CC levels and AHI showed that CC levels were positively correlated with AHI (r =0.585,P ＜ 0.01).However,there were no statistically significant differences between CC levels of the mild OSAS group and control group (P ＞ 0.05).Conclusions The patients with OSAS and primary hypertension had higher levels of CC,and aggravated with the progress of the degree of obstruction.CC may be involved in the progression of the disease,a high level of CC may aggravate the condition,it should be early prevention and treatment.

ObjectiveTo investigate the effect of out-patient training combined with family training under doctor's instructions on children with cerebral palsy (CP).Methods80 CP children were selected as treatment group and trained one to three months by therapists at out-patient department, then continually trained at family by parents who received doctor's instructions 30 min once every two or three months. 60 CP children in hospital were selected as control group. Rehabilitative effects of two groups were compared.ResultsIn the first and third month after training completed, movement growth of treatment group was not different from that of control group (P>0.05), but in the sixth month, was significant different from that of control group (P<0.05). The effect of treatment group was better than that of control group.ConclusionOut-patient training combined with family training under doctor's instructions can decrease treatment expenses, and is convenient and effective for CP children.
