Objective: To study the antiemetic effect of the ethyl acetate extract with ethanol extraction of Galangal (hereinafter referred to as galangal extract) in allotriophagic Kaolin model rats.Methods: The rats were administered respectively with chemical drug cisplatin and apomorphine, and received the rotation stimulation as well.Three types of allotriophagic Kaolin models were established, and apomorphine, ondansetron and metoclopramide were used as the control drugs.The experimental rats were divided into 3 groups at low, medium and high dose of Galangal extract with prophylactic effect.The antiemetic effect was observed after the treatment.Results: Chemical drug cisplatin (3.0 mg·kg-1, intraperitoneal injection) and apomorphine (3.2 mg·kg-1,subcutaneous injection) and the rotation stimulation (centrifugal force of 3.4×g,60min) could induce allotriophagic vomiting in rats.The galangal extract at low (1 500 mg·kg-1), medium (4 500 mg·kg-1) and high (9 000 mg·kg-1) dose all fail to effectively inhibit the allotriophagic Kaolin behavior of rats caused by cisplatin, apomorphine and rotation(P>0.05).Conclusion: Galangal extract can not effectively inhibit the vomiting of allotriophagic Kaolin model rats.Probably, there is no correlation between the pharmacological effects of galangal extract and substance P, 5-hydroxytryptamine, dopamine as well as receptive zone of chemical vomiting inhibition.

Objective To investigate the changes of hematoma and perihematomal edema in spontaneous hypertensive rats (SHRs),as well as the correlation between blood pressures and perihematomal edemaMethods A total of 24 6-month-old male SHRs were included.They were randomly divided into intracerebral hemorrhage 1-,3-,5-,and 7-day groups (n =6 in each group).Blood pressure was determined by tail-cuff sphygmomanometry.Collagenase Ⅳ was injected into caudate nucleus in order to induce a model of intracerebral hemorrhage.Magnetic resonance T2 weighted imaging was used to observe hematoma and perihematomal edema.Results On day 1 after modeling,the blood pressure was decreased significantly compared to that before modeling,and it was elevated gradually on day 3.Parallel profile test showed that the overall profile was parallel between the change rate of blood pressure and the change rate of perihematomal edema volume (F =2.820,P =0.063).The coincident profile test showed that both the overall profiles did not coincide (F =10.961,P =0.000).The change rate of systolic blood pressure was significantly positively correlated with the change rate of perihematomal edema volume (r =0.527,P =0.024) and the change rate of perihematomal edema volume (r =0.755,P =0.000) showed a significant positive correlation.Conclusions Brain edema appeared and expanded rapidly on the day of intracerebral hemorrhage in SHRs.It reached the peak on day 3,and then dissipated gradually.The blood pressure decreased significantly on day 1 after intracerebral hemorrhage,and it began to increase from day 3 till day 7.The changing trends of the blood pressure and perihematomal edema volume were parallel to each other,and the change rate of systolic blood pressure and the change rate of perihematomal edema volume showed a positive correlation.

Objective To assess the clinical feature of older-onset systemic lupus erythematosus.Methods A retrospective study was carried out.Clinical and laboratory findings were collected from 48 patients with older-onset (＞ or =50 years) SLE as well as 424 patients with younger-onset (＜ 50 years) SLE hospitalized in the First Affiliated Hospital of Zhengzhou University from January 2008 to January 2011.Results Among the 472 hospitalized patients with SLE,the ratio of male to female was 1 ∶ 8.08,and older-onset SLE accounted for 10.17％.No significant difference was observed in the incidence of fever,arthritis,decrease in hemoglobin level,increase in erythrocyte sedimentation rate and reduction in complement C4 level,or the positivity rate of anti-ribonucleoprotein (RNP) or anti-Sm autoantibodies (all P ＞ 0.05) between the older-onset and younger-onset SLE patients.The patients with older-onset SLE showed a statistically higher incidence of myalgia,myasthenia,serositis,heart damage and lung damage,decrease in white blood cell count and platelet count,but a significantly lower incidence of butterfly rash,alopecia,renal damage,Raynaud's phenomenon,photosensitivity,decrease in complement C3 level,as well as the positivity rate of anti-dsDNA and anti-nucleosome antibodies in comparison with those with youngeronset SLE (all P ＜ 0.05).Conclusions It is likely that older-onset SLE has mild and atypical clinical manifestations,with a relatively low positivity rate of specific immunological indices.Hence,clinicians should pay more attention to older-onset SLE so as to avoid the misdiagnosis or missed diagnosis of it.

Objectives:To analyze the level and related factors of quality of life, caregiver burden in primary caregivers of adolescents with depression, and to explore the relationship between quality of life and caregiver burden. Methods: Totally 180 caregivers of adolescents with depression were investigated in the Second Xiangya Hospital of Central South University in Changsha, Hunan province. The Hamilton Depression Scale-17 (HAMD-17), Short Form 36 Health survey Questionnaire (SF-36) and Zarit Caregiver Burden Interview (ZBI) were used to assess depressive symptoms of patients, the quality of life and caregiver burden of primary caregivers of adolescents with depression. Results:The scores of SF-36 dimensions were lower in caregivers than in the national norm (P ＜ 0.01). The average score of ZBI was (32 ± 15), while 73.7％ caregiver's burden was in the low and moderate level. The SF-36 scores were lower in caregivers taking care of patients with longer course of disease and suicide history, with lower education level, with lower family income (P ＜0.05). The ZBI scores were higher in those taking care of the patients in hospital, with a long course of disease, with higher HAMD scores, and those with major events in the past 3 months, and being on-the-job, (P ＜0.05). The caregiver burden (personal burden and role burden) of caregivers was negatively related to the scores of quality of life (physical health and mental health) (r=-0.56——0.24, Ps ＜0.01). Conclusion: The quality of life of caregivers of adolescents with depression is severely impaired, and they have obvious caregiver burden. The caregivers with lower education level, lower family income, and being on-the-job, with major events in the past 3 months, and those taking care of patients with a long course of disease, suicide history, and higher HAMD score may have heavy burden and low quality of life. The caregiver burden of caregivers of adolescents with depression is negatively related to their quality of life.

Objective:To investigate the effect of self-help cognitive behavioral intervention on the recovery of patients with generalized anxiety disorder.Methods:A total of 123 patients with generalized anxiety disorder were recruited from a comprehensive hospital in Hunan province. The patients were randomly assigned into control group( n=62) and intervention group( n=61) according to random number table. The patients in the control group were received routine treatment alone, while the patients in the intervention group were received routine treatment and WeChat-based self-help cognitive behavioral therapy. The generalized anxiety disorder(GAD-7), self-rating depression scale(SDS), WHO quality of life scale(WHOQOL-BREF), Pittsburgh sleep quality index(PSQI) and medication adherence scale(MARS) were used to measure the anxiety, depression, quality of life, sleep quality and medication compliance at three time points: before intervention (T1), after intervention (T2) and during follow-up (T3). The SPSS 21.0 was used to analyze the data.Mean±standard deviation, frequency and constituent ratio were used to describe the data based on the type of data. Repeated measure ANOVA was used to compare the between-group variation, time effect and interaction effect of two groups at 3 time points. Results:The anxiety score of intervention group at T1, T2, T3 were (12.74± 2.02), (7.13± 1.48), (6.57±1.73) respectively, and the anxiety score of the control group were (12.08±2.11), (11.11±3.27), (10.11±3.33) respectively. Compared with the control group, the score of anxiety in the intervention group was significantly decreased at T2 and T3 ( P<0.05). Compared with control group, the sleep quality and quality of life of intervention group were significantly improved at T2, T3 ( P<0.05), and the medication compliance of the intervention group was significantly improved at T3 ( P<0.05). Conclusion:Self-help cognitive behavioral intervention can decrease anxiety significantly and improve the quality of life, sleep quality, and medication compliance in patients with generalized anxiety disorder.

Objective To observe the oral part of the facial artery and facial vein and to provide anatomical data for clinical applica-tion. Methods The origin, branches, course, diameter, position of oral part of facial artery and facial vein were observed on 32 fixed cada-ves (64 sides). Results The position relation between the facial artery and facial vein is non-constant. Measure the distance from inferior border of mandible to corner of the mouth, angulus mandibulae, mental protuberance midpoint. It is (5. 49 ± 0. 63) cm, (2. 50 ± 0. 89) cm and (6. 20 ± 1. 68) cm in the left side respectively, and (5. 69 ± 0. 72) cm, (2. 56 ± 1. 08) cm and (6. 85 ± 1. 86) cm in the right side re-spectively. The diameter of facial artery in inferior border of mandible is (0. 33 ± 0. 08) cm in the left side and (0. 38 ± 0. 07) cm in the right side;while the diameter of facial vein is (0. 40 ± 0. 12) cm in the left side and (0. 42 ± 0. 18) cm in the right side. The facial artery and facial vein are not concomitant and they are not asymmetry also. The position of superior labial artery arteries is constant, but the position of inferior labial artery arteries have more variations. Conclusion The branches, course, diameter and position of oral part of facial artery and facial vein have a number of variations. The superior labial artery arteries could be positioned more easily than inferior labial artery arter-ies. Being familiar with their distribution is of great importance for clinical application.

BACKGROUND:As a member of bone morphogenetic proteins,growth differentiation factor-5 shows promising potential in the application of cartilage and bone repair.The affinity of growth differentiation factor-5 onto bone tissue determines protein use efficiency,so it is of great significance to prepare growth differentiation factor-5 with bone targeting capability. OBJECTIVE:To modify growth differentiation factor-5 using bisphosphonates and investigate the effects of modified protein on the growth of preosteoblasts in mice. METHODS:Pamidronate disodium/growth differentiation factor-5 complex was prepared using chemical crosslinking to couple growth differentiation factor-5 with pamidronate disodium.The functional groups and structures of the complex were characterized using Fourier transform infrared spectroscopy and circular dichromatography.To determine the bone targeting in vitro,the binding of the modified growth differentiation factor-5 with calcium phosphate and in vitro release amount of growth differentiation factor-5 were measured with an ELISA kit.Growth differentiation factor-5(control group)and the pamidronate disodium/growth differentiation factor-5 complex(experimental group)were co-cultured with preosteoblasts MC3T3-E1.Individually cultured cells were blank controls.The effect of the complex on cell proliferation and differentiation was evaluated. RESULTS AND CONCLUSION:(1)The infrared spectroscopy and circular dichromatography results indicated that the bisphosphonate/growth differentiation factor-5 complex was successfully prepared without significant changes in the protein secondary structure.In vitro protein adsorption results showed that growth differentiation factor-5 adsorption on calcium phosphate was increased by about one time after coupling with a bisphosphonate.In the presence of cysteine,growth differentiation factor-5 could be released from the bisphosphonate/growth differentiation factor-5 complex.(2)CCK-8 assay results showed that the absorbance value of the experimental group cultured for 4 and 7 days was higher than that of the control group and blank control group(P<0.000 1).After 7 days of culture,the expression of alkaline phosphatase in the experimental group was significantly higher than that in the control group and blank control group(P<0.000 1).After 13 days of culture,the content of calcium nodules in the experimental group was significantly higher than that in the control group and the blank control group(P<0.000 1).The results of qRT-PCR showed that the mRNA expression of alkaline phosphatase,osteocalcin and Runx2 in the experimental group was higher than that in the control group and the blank control group after 7 days of culture(P<0.01,P<0.001,P<0.000 1).(3)These findings exhibit that bisphosphonate modification can enhance the binding capacity of growth differentiation factor-5 to calcium phosphate as well as improve its biological activity.

OBJECTIVE To study the effects of transferrin-targeting peptide T7 （7pep） on intracellular transportation of polyethylene glycol-polycaprolactone （PEG-PCL） micelles in human cervical cancer HeLa cells. METHODS Using coumarin-6 （C6） as fluorescent indicator probe， both coumarin-6 （C6）-loaded PEG-PCL （PEG-PCL-C6） micelles and 7pep-modified PEG- PCL （7pep-PEG-PCL-C6） micelles were prepared by film-dispersion method. The particle size， polydispersity index and appearance morphology were compared between two types of micelles； the real-time uptake of two types of micelles by HeLa cells was compared， and the colocalization of two types of micelles with early endosomes （EE）， endocytic recycling compartments （ERC） and late endosomes （LE） after entry into the cells was observed. RESULTS The particle sizes of PEG-PCL-C6 and 7pep-PEG-PCL- C6 micelles were（75.0±2.3）and（82.0±1.5）nm； the polymer dispersity indexes were 0.17±0.20 and 0.17±0.32， respectively， with a regular spherical appearance. The colocalization results showed that entry speed and amount of 7pep-PEG-PCL-C6 micelles were significantly faster/more than those of PEG-PCL-C6 micelles. 7pep-PEG-PCL-C6 micelles entered EE faster than PEG-PCL-C6 micelles， while PEG-PCL-C6 micelles entered ERC at a faster rate than 7pep-PEG-PCL-C6 micelles， and both PEG-PCL-C6 micelles and 7pep-PEG-PCL-C6 micelles tended to accumulate gradually in LE； Pearson coefficient， signal overlap ratio， and colocalization ratio of 7pep-PEG-PCL-C6 micelles with LE were significantly lower 60 minutes after entering the cell than those 30 minutes after entering the cell （P＜0.05 or P＜0.01）. CONCLUSIONS Targeting 7pep modification can increase the entry speed and amount of PEG-PCL-C6 micelles， and also alter their intracellular transportation behavior.
