Objective To study the effects of serum of the Zhuartgguqiang jin tablets on the proliferation and osteogenic differentiation of bone marrow stromal stem cells (BMSCs) of aged rats.Methods The BMSCs were obtained from male SD rats of 18 months.The cell surface markers CD34,CD31,CD29 were detected by flow cytometry.The proliferation of BMSCs treated by different concentration of medicated serum (2.5％,5％,10％) at 24,48,72hours was detected by CCK-8 method.The BMSCs were divided into 4 groups,which were osteogenic induction group,the Chinese medicated osteogenic induction group,Chinese medicine group,the blank group.After the BMSCs were cultured for 7 days,alkaline phosphatase (ALP) vitality was detected.After the BMSCs were cultured for 14 days,the BMSCs were stained by alizarin red,the mRNA of ALP and osteocalcin(OC) was detected.Results The expressionof CD29 was positive,and the expression of CD31 and CD34 were negative.2.5％,5％ of the medicated serum could promote cell proliferation.The ALP vitality of osteogenic induction group[202.76 ± 15.44(U/gprot)],the Chinese medicated osteogenic induction group [240.48 ± 18.55 (U/gprot)],Chinese medicine group [178.87 ± 17.29 (U/gprot)]were significantly higher than that of blank group [111.24 ± 20.71 (U/gprot)] (t =22.50,7.985,3.535,all P ＜0.01).The ALP activity of Chinese medicated osteogenic induction group was higher than that of osteogenic induction group (t =3.103,P ＜ 0.05).The ALP gene relative OD value of osteogenic induction group (0.40 ± 0.20) and Chinese medicated osteogenic induction group (0.60 ± 0.06) were higher than the blank group (0.09 ± 0.03) (t =2.372,9.547,all P ＜0.01).The ALP gene expression of Chinese medicated osteogenic induction group was obviously higher than that of the osteogenic induction group(P ＜0.05).The OC gene relative OD value of osteogenic induction group(0.58 ± 0.09) and Chinese medicated osteogenic induction group(0.76 ± 0.11) were higher than the blank group(0.41 ± 0.02) (P ＜ 0.05,P ＜ 0.01).The OC gene expression of Chinese medicated osteogenic inductiongroup was obviously higher than that of the osteogenic induction group(t =2.673,P ＜ 0.05).Conclusion Medicated serum of Zhuangguqiangjin tablets can promote the proliferation and osteogenic differentiation of BMSCs of aged rats,which may be the mechanism of prevention senile osteoporosis.

ObjectiveTo observe the effect of bubble bath coordinating with functional training on the children with spastic cerebral palsy.Methods210 children with spastic cerebral palsy were randomly divided into the treatment group (n=118) and control group (n=92). All children were treated with functional training, acupuncture and other physical therapies. Children in the treatment group were added with bubble bath one time every day, twenty days as one course. Muscular tension was evaluated with modified Ashworth Scale and range of motion was measured before and after treatment.ResultsIn the treatment group, 55 cases were significant, 53 cases were effective, 10 cases were invalid, the total effective rate was 91.5%; in the control group, 26 cases were significant, 46 cases were effective, 20 cases were invalid, the total effective was 78.2%. There was a significant difference between the total effective rates of two groups (P<0.05).ConclusionBubble bath can significantly decrease the muscular tension of children with spastic cerebral palsy.

Objective To explore the clinical effects of sequential flap of thigh perforator for closure of the anterolateral thigh free flap donor site.Methods From March,2014 to May,2015,8 consecutive patients underwent elective anterolateral thigh free flap reconstruction for limb soft tissue defect.To design a sequential flap of thigh perforator to achieve primary closure of the anterolateral thigh free flap donor site.The area of anterolateral thigh free flap ranged from 9.0 cm×6.0 cm to 20.0 cm×1 1.0 cm,respectively.The area of thigh perforator flap ranged from 7.0 cm×3.0 cm to 12.0 cm×7.0 cm.Results All flaps healed uneventfully.Distal skin flap necrosis appeared in 1 flap which was healed after local transposition flap.All the patients were followed up for 1 to 6 months,with mean time of 4 months.The color,texture and appearance of flaps were satisfactory.Conclusion Sequential flap of thigh perforator,with reliable blood supply and constant position,represents an ideal model to close the anterolateral thigh free flap donor site of small defect.

Objective To observe the influence of gender in cortical spreading depression (SD) wave in mice.Methods Potassium chloride (KCl) or middle cerebral artery occlusion (MCAO) models were used to induce SD.Adult C57 mice were randomly divided into four groups:male and female KCl-induced groups,male and female MCAO-induced groups (n=8).SD waves were monitored for 2 h by electrophysiological method.Results SD waves showed lower amplitude and longer duration time in the MCAO-induced group as compared with those in the KCl-induced group.There were no obvious differences in SD amplitude,duration time,frequency and onset time of first SD between male and female KCl-induced groups (P＞0.05).There were no differences in SD amplitude and duration time between male and female MCAO-induced groups (P＞0.05),however,SD frequency and onset time of the first SD were signficantly different between male and female MCAO-induced group (P＜0.05).Conclusion Mice gender has an effect on MCAO-induced SD,but no obvious effect on KCl-induced SD; the possible explanation for the difference is that estrogens modifying susceptibility to SD is mainly through their effect on glutamate but not on K+ metabolic pathways.

Objective To investigate the situation of human papillomavirus (HPV) infection and the distribution of HPV genotypes among women attending hospital in Meizhou,Guangdong province.Methods Flow-through hybridization and gene chip technique was used to detect HPV in cervical exfoliated cell specimens collected from 24 450 women for HPV screening in Department of Gynecology,Meizhou People's Hospital,Meizhou Hospital Affiliated to Sun Yat-sen University,and then the situation of HPV infection and distribution of HPV genotypes were analyzed.Results Among 24 450 female exfoliated cell specimens,3 922 were found to be positive for HPV infection,with the total infection rate of 16.04％.Among 3 922 samples,the top three high-risk subtypes of HPV were HPV-16 (30.37％),HPV-52 (17.77％) and HPV-58 (15.53％),the majority of low-risk HPV was HPV-CP8304 (5.61％).The positivity of various HPV types peaked among 30-50 years old.The differences of the HPV positive rates in different age groups was statistical significance (P ＜ 0.001).Conclusions The majority of women attending hospital detected with HPV-16 in Meizhou and the positivity of various HPV types peaked among women aged 30-50 years.Genotyping of HPV was meaningful for preventing and treating cervical cancer.
