Objective To investigate perioperative anxiety and depression of patients undergoing prosthetic augmentation mammoplasty.Methods A total of 123 patients undergoing prosthetic augmentation mammoplasty were involved in the retrospective analysis.Hamilton anxiety scale (14 Edition) and Hamilton depression scale (version 24) were used to evaluate anxiety and depression perspectively before and after surgery.The data were subjected to statistical analysis and correlation factor analysis.Results We found that anxiety scale scores had significant difference before and after surgery (P＜0.05),and ression scale scores had no significant difference (P＞0.05).We also found that the anxiety after surgery were positively correlated with anxiety and depression before surgery (r=0.377,0.313,P=0.001),and the depression after surgery was also positively correlated with anxiety and depression before surgery (r=0.359,0.298,P=0.001).It suggested the patients with symptoms of anxiety and depression before surgery might appear the same symptoms within a week after surgery.Conclusions Anxiety symptoms before surgery in patients with prosthetic augmentation mammoplasty are significantly higher than that after surgery,but the symptoms decrease when finished surgery.The patients with symptoms of anxiety and depression before surgery probably present with symptoms of anxiety and depression in a week after surgery.

BACKGROUND: Proliferation and differentiation of mesenchymal stem cells (MSCs) is associated with platelet concentration in platelet-rich plasma (PRP). Low enrich multiple cannot reach proper effects, but high level had inhibitory effects on osteoanagenesis.OBJECTIVE: To observe the effect of different volume fraction of PRP on dog BMSC proliferation.DESIGN: A cytological in vitro study.MATERIALS: Healthy 12-month male Beagle dogs were supplied by the Experimental Animal Center, Xiangya Medical College,Central South University.METHODS: Dog BMSCs of 5 passage were adjusted to 3×10~8/L, and incubated in a 96-well plate at 200 μL per well. Following 24 hours of routine culture, primary medium and non-adherent cells were discarded. Prepared PRP gel was mixed with serum-free low-glucose DMEM containing penicillin and streptomycin, and then diluted into 5%, 6.25%, 7.5%, 8.75%, 10% volume fraction. 200 μL above-described liquid was added into the 96-well plate, which was subsequently placed in a incubator.We set up a blank control.MAIN OUTCOME MEASURES: MTT was used to investigate effect of different volume fraction of PRP on dog BMSC proliferation.RESULTS: Compared with the blank control group, various volume fraction of PLP could promote dog BMSC proliferation in early stage. With prolonged time, proliferation speed began to increase at day 6 in the 8.75% and 10% PRP groups, entering platform stage. BMSC number was increased rapidly in the 5% and 6.25% PRP groups, especially in the 6.25% PRP group.CONCLUSION: PRP gel could promote BMSC proliferation markedly and proliferation strength of BMSCs was correlated to the density of PRP. BMSC proliferation would be accelerated by the low density of PRP.

BACKGROUND: Platelet-rich plasma (PRP) contains abundant growth factors that were needed for osteanagenesis. Moreover,the proportion of each growth factor formed by an organism, with good synergism.OBJECTIVE: To explore the influence of PRP on osteogenetic activity of canine bone marrow mesenchymal stem cells (BMSCs) after induction in vitro.DESIGN, TIME AND SETTING: The in vitro cytological experiment was performed at the Central Laboratory of Xiangya Hospital of Central South University from June 2007 to February 2008.MATERIALS: Healthy 12-month male Beagle dogs were supplied by the Experimental Animal Center, Xiangya Medical College,Central South University.METHODS: The 3~(rd) generation BMSCs were collected and divided into 4 groups. BMSCs in the control group were incubated in standard medium. BMSCs in the osteogenetic induction medium group were incubated in high-glucose DMEM containing fetal calf serum, dexamethasone, beta-sodium glycerophosphate and vitamin C. BMSCs in the PRP group were incubated in low-glucose DMEM containing 6.25% PRP. BMSCs in the combination group were incubated in high-glucose DMEM containing 6.25% PRP, dexamethasone, beta-sodium glycerophosphate, and vitamin C.MAIN OUTCOME MEASURES: Alkaline phosphatase activities were measured. Expression of collagen type I was examined by immunocytochemical staining. Calcium tuberoses were labeled using modified Von Kossa staining. Expression of osteocalcin mRNA was examined by RT-PCR.RESULTS: Levels of alkaline phosphates of all groups became increased along with time. The alkaline phosphates level of combination group was strongest (P < 0.05). Following 7 and 14 days of induction, type I collagen expressed positively in the osteogenetic induction medium and combination groups, but negatively in the PRP and control groups. Following 14 days,formation of calcium nodules were found in the osteogenetic induction medium and combination groups. Following 7 and 14 days,expression of osteocalcin mRNA were similar between the control and PRP groups (P > 0.05), which was significantly lower than the osteogenetic induction medium and combination groups (P < 0.05). Expression of osteocalcin mRNA was significantly lower in the osteogenetic induction medium group compared with the combination group (P < 0.05).CONCLUSION: PRP gel can effectively promote osteoblastic effect of BMSCs after induction in vitro following induction in osteogenetic medium.

OBJECTIVE:To establish a method for determining recombinant human calmodulin B subunit(rhCNB)in rat plas-ma,and study its pharmacokinetics characteristics. METHODS:ELISA double-antibody sandwich method was adopted. 1 μg/ml rhCNB monoclonal antibody mAb was wrapped,added to the to-be-test sample,rhCNB polyclonal antibody pAb(dilution ratio of 1∶5 000)and HRP-labeled conjugate of anti-IgG(dilution ratio of 1∶10 000)were added. Using tetramethylbenzidine for develop-ing,microplate reader was conducted in wavelength of 450 nm to determine the absorbance value(OD value)and plasma concen-tration of 6 rats after 2,15,30,60,120,240,480,720 min of iv 2.5 mg/kg rhCNB,and the pharmacokinetic parameters were calculated by BAPP 3.0 software. RESULTS:The linear range of rhCNB were 0.195-12.5 ng/ml(r2=0.995 0),lower limit of quan-titation was 0.195 ng/ml,accuracy were 97.300%-103.622%(RSD<7.5%,n=6);RSDs of within-batch,inter-batch,freezing and thawing 3 times were no higher than 8.5%(n=6,18,15). rhCNB pharmacokinetics characteristics in rat fitted to two-com-partment model,AUC0-720 min was 173.038 mg·min/L and t1/2 was 94.62 min. CONCLUSIONS:The established method has high specificity and sensitivity,good accuracy and precision,which can be used for rhCNB quantitative detection and pharmacokinetics study in biological samples.

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.
