Contents of magnolol and honokiol in Magnolia officinalis Rehd. et Wils. and its processed products,yellow-fried, burn -fried and ginger-fried M. officinalis Rehd. et Wils. as well as commercially available M.officinalis Rehd. et Wils. and its processed products were assayed by TLC Scanning. Results showed that contents of the two constituents decreased after M. officinalis Rehd. et Wils. was processed. Among them the burn-fried product showed a most pronounce decrease of 30%, while both yellow-fried and ginger-fried products decreased about 20%. The contents of magnolol and honokiol in commercial M. officinalis Rehd. et Wils. and its ginger-fried product available in other provinces and cities differed greatly with some almost contain no magnolol and honokiol.

Objective To retrospectively evaluate effects of early dynamization of interlocking intramedullary nail on union of tibial shaft fractures.Methods From January 2002 to Septemher 2004,75 patients with tibial shaft fractures were treated in our department with internal fixation using static interlocking iutramedullary nails.Early dy- namization(6 to 10 weeks postoperative)was adopted in 32 patients (the dynamic group) according to the fracture con- ditions,while the other 43 patients were treated without early dynamization (the non-dynamic group).The healing time of fractures and the rate of delayed union in both groups were documented.Results All the cases were followed up for a mean duration of 6.5 months (range,4 to 13 months).The mean healing time was 115.6 days (range,105 to 126 days) in the dynamic group and 124.5 days (range,119 to 133 days) in the non-dynamic group.The difference was statistically significant between the two groups (P<0.05).There were two cases (6.2%) of delayed union in the dynamic group and four (9.4%) in the non-dynamic group.The difference was not significant (P>0.05). Conclusion Early dynamization of interlocking intramedullary nail can promote union of tibial shaft fractures.

Objective To investigate the application of a new type internal anastomotic appliance of pouch pliers in the retention of anus operation of mesal,low rectal carcinoma.Methods The data of 65 patients with mesal,low rectal carcinoma with the technique of the anal retention using KYGW type anastomotic appliance of pouch pliers were reviewed and analyzed retrospectively.Results 65 patients were coincided success only one time. Anastomotic fistula occurred after operation in 1 case,being cured and discharged at last,no anastomotic stricture. Conclusion The internal anastomotic appliance of pouch pliers in the anal retention of mesal-low rectal carcinoma is an efficient method with better cost-effectiveness and fewer complications,which is easy to manipulate and popular- ize.

Objective To investigate the effect of pemetrexed on the immune function,quality of life and survival time of patients with malignant pleural effusion.Methods Eighty cases patients with non-small cell lung cancer from July 2013 to October 2015 in the People′s Hospital of Hunan Province were complicated with pleural effusion,and randomly divided into observation group and control group,40 cases in each group.The control group were used chemotherapy with GP(gemcitabine plus cisplatin) and the central venous catheter was placed in the thoracic cavity.The observation group was treated with retrograde injection of pemetrexed catheter on the basis of the control group.The changes of immunoglobulin and inflammatory cytokines were compared between the two groups,and the quality of life and the 1 year survival rate of the two groups were statistically analyzed.Results The IgM,IgG and IgA of the observation group after the intervention were higher than those in control group((1.65±0.03) mg/L vs.(1.31±0.02) mg/L,(9.55±0.12) mg/L vs.(8.82±0.10) mg/L,(3.99±0.20) mg/L vs.(1.81±0.13) mg/L,t=59.640,29.557,57.800,P<0.05),the TNFα-,IL-1,hs-CRP levels of the observation group after the intervention were lower than the control group((12.0±0.2) μg/L vs.(18.1±0.5) μg/L,(0.60±0.1) mg/L vs.(0.92±0.2) mg/L,(10.3±1.0) mg/L vs.(31.3±2.0) mg/L,t=71.641,9.051,59.397,P<0.05),and quality of life score after the intervention than before((81.5±2.3) points vs.(81.6±2.3) points,(35.3±1.1) points vs.(56.6±1.7) points,t=114.608,55.823,P<0.05).Quality of life of the observation group was better than the control group(t=66.530,P<0.01),1 year survival rate was higher than the control group(25.0%(10/40) vs.50.0%(20/40),U=5.903,P<0.05).Conclusion Local chemotherapy with pemetrexed could significantly improve the immune function of patients with malignant pleural effusion,reduce the inflammatory response,improve the quality of life and prolong the survival time of patients with malignant pleural effusion.

This study aims to explore the differences of event-related potential (ERP) between attention deficit hyperactivity disorder (ADHD) and normal children, so that these differences provide scientific basis for the diagnosis of ADHD. Eight children were identified to be ADHD group by the diagnostic criteria of DSM-IV (diagnostic and statistical manual of mental disorders-IV), and the control group also consisted of 8 normal children. Modified visual-continuous performance test (CPT) was used as the experiment paradigm. The experiment included two major conditions, i. e. Go and NoGo. All the 16 subjects participated in the study. A high density EEG acquisition instrument was used to record the EEG signal and processed these EEG data by means of ERP and spectrum analysis. P2-N2 peak-peak value and spectral peak around 11 Hz were analyzed between ADHD subjects and those in the control group, and then statistical tests were applied to these two groups. Results showed that: (1) Under the condition of Go, ADHD group had a significant lower P2-N2 peak-peak value than the values in the control group (P < 0.05); but under the condition of NoGo there was no significant difference in between. (2) Compared with the control group, the ADHD group had significant lower spectral amplitude around 11 Hz under the condition of NoGo (P < 0.05). However, under the condition of Go the difference was insignificant. In conclusion, there is certain cognitive dysfunction in ADHD children. P2-N2 peak-peak value and spectral peak around 11 Hz could be considered as clinical evaluation indexes of ADHD children's cognitive function. These two objective indexes provide an early diagnosis and effective treatment of ADHD.

Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P>0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.
