Objective To observe the therapeutic effect of Sanzi Yangqing Decoction (Decoction of three kinds of seeds) for mammary cystic hyperplasia.Methods Totally 113 patients with mammary cystic hyperplastia were randomized into a treatment group (58 cases) which was prescribed Sanzi Yangqing Decoction and a control group (55 cases) which was given Ruhe Sanjie Tablet (Tablet for dissolving mammary masses). Both were treated for 3 courses. Before and after treatment the clinical symptoms and signs, hormones in serum of both groups, and the indices of hemodynamics of the treatment group were observed.Results The total effective rate of the treatment group was 89.66%, while that of the control group was 65.45%, there was significant difference (P

[Objective]To study the feasibility and significance of a safe arthroscopic entrance technique to posterior compartment of the knee joint.[Method]Exploratory surgery of posterior compartment of 239 knee joints was performed by arthroscope or its working instruments through the combined entrances of anteromedial,anterolateral,intercondylar notch,posteromedial,posterolateral and trans-septal.Their results were evaluated.[Result]With this technique,complete arthroscopic visualization of the posterior compartment of knee joint and arthroscopic procedures for this compartment could be easily performed in 216 cases(239 knees),except 5 cases with arthro-stiffness.There occurred 1 case of saphenous nerve injury but no complications such as injuries of popliteal neurovascular structures.[Conclusion]Combined entrances of posterior compartment of knee joint is a satisfactory approach for arthroscopic surgery of posterior compartment of knee joint and can give a high efficiency and quality of arthroscopic surgery for posterior compartment of knee joint.

Objective: To explore the effect of 32h sleep deprivation on the ability of mental rotation. Methods: During 32h sleep deprivation, 8 healthy male college students were tested polygon mental rotation tests and POMS tests at 0800?2000?2400?0200?0400?0600?1000 and 1400 hour. Results: During sleep deprivation, the performance of polygon mental rotation test was decreasing significantly and it reached the bottom on SD24 (p

Objective To explore the differences between the minority nationality and Han recruits in army occupational adaptability.Methods 3 213 recruited youths coming from 29 autonomous counties of minority nationalities,Yunnan Province were tested by 2011 Chinese enrollment psychological test system to explore the differences of the intelligence adaptability and character trait adaptability between the minority nationality and Han recruits.Results There were obvious differences in the eligible rates of intelligence and character trait between minority nationality and Han recruits ( x2 =13.3,9.0; P ＜ 0.01 ).The intelligence eligible rates of Yi,Hani,Wa recruits (78.1％,76.8％,68.2％,respectively) were significantly lower than those of Han recruits (84.0％) (P＜0.01 ),and time used in three intelligence test was all significantly longer than Han recruits(P ＜ 0.05 ).Naxi and Dai recruits' time used in word reasoning ( ( 109.2 ± 20.9) s; ( 123.9 ± 32.5 ) s,respectively) was both longer than Han recruits' (P＜0.01).In the fact of character trait,the eligible rates of Hani,Wa recruits (67.8％,64.3％,respectively) were significantly lower than that of Han recruits (78.1％) (P ＜ 0.01 ).The Hani average score of T dimension (57.9 ± 17.5) was obviously higher than the Han's score (52.2 ± 16.5) (P ＜ 0.05 ).All dimensions average scores except T and D dimension of Wa recruits were all significantly higher than those in Han recruits(P ＜ 0.05 ).Conclusion Every minority nationality has its unique differences in armyoccupational adaptability from Han.Ethnic factor may be an important reference for new recruits' selection,education and management.

OBJECTIVE: To study the modulation of Jianjining Recipe (JJNR), a traditional Chinese compound herbal medicine for invigorating spleen and kidney on differential protein expression in spleen of rats with experimental autoimmune myasthenia gravis (EAMG). METHODS: EAMG rats were randomly divided into four groups: untreated group, JJNR-treated group, Qiangji Jianli capsule (QJJLC, a traditional Chinese compound herbal medicine)-treated group and prednisolone acetate (PA)-treated group. After therapeutic intervention with the above drugs for four consecutive weeks, the level of differential protein expression was analyzed by two-dimensional electrophoresis and matrix assisted laser desorption/ionization time-of-flight mass spectrometry. RESULTS: Twelve differential proteins were identified by comparing EAMG rats and normal rats. The levels of allograft inflammatory factor-1, peroxiredoxin I and actin-related protein 2/3 complex subunit 5 were significantly regulated by JJNR (P<0.01). These proteins were closely associated with immune response and cell movement. CONCLUSION: The results suggest that there are differential protein expressions between EAMG rats and normal rats. Furthermore, as a Chinese medicine prescription with effect of invigorating spleen and kidney, JJNR can effectively regulate the levels of some EAMG-related protein expression.

Objective To explore the effect of weightlessness simulation on processing speed of mental rotation of males in 72 h head-down tilt,in order to further reveal human performance changes caused by weightlessness.Methods During 72 h weightlessness simulation (9 am day 1 to 9 pm day 4,head-down tilt started from 9 pm day 1),16 male subjects were processed speed of rotation data byhand picture mental rotation (test 8 times),using self cross-references design,and the variation of processing speed of mental rotation by duration was analyzed.Results The linear regression analysis showed,the reaction time of each time point for each subject as the independent variable,the angle of rotation as the dependent variable,with the extension of simulated weightlessness time.The intercept(constant term of the regression equation),indicating the processing speed of non-rotation,were gradually increased with HDT time,but didn(t) reached significantly difference (F(3,14) =0.551,P =0.650) ;the slope(Regression coefficient of the regression equation),indicating the processing speed of rotation.were gradually increased with HDT time,and reached the significantly difference (F(3,14) =4.338,P =0.009).The value of intercept and slope was like upside-down U in three days,and reached the highest value at day 2.Conclusion Weightlessness simulation have affection on the speed of mental rotation,especially on the rotation speed.

Liver diseases are serious diseases harmful for human health. CCl4 induced liver injury, as a classic liver injury model, has been widely used in the screening of hepatoprotective drugs. This paper reviewed the research progress in the hepatoprotective effect of traditional Chinese medicines ( TCMs) on CCl4 induced acute liver injury in recent years, which can provide basis for searching TC-Ms with high efficiency and low toxicity and lay foundation for TCMs in the treatment of liver diseases.

Objective To explore the time course of response inhibition function in juvenile delin-quents with antisocial personality characteristics.Methods The healthy control group ( n=21),juvenile delinquents with antisocial personality characteristics ( CD +AP ) ( n=18) and juvenile delinquents ( CD) ( n=18) were selected in current study by recording the event-related potentials in a Go/Nogo task.N2 and P3 components of event-related potentials were analyzed.Results Behavioral results showed that Nogo cor-rection rate of control group ((93.13±2.71)%) were significantly higher than CD group ((87.51±2.82)%, P<0.01) and CD +AP group((85.63±2.45)%, P<0.01).In CD+AP group,the amplitude of the N2nogo ( (-1.82±1.64)μV) was significantly lower than control group ( (-6.36±2.93)μV, P<0.01) ,and the am-plitude of the P3nogo ((5.52±2.79)μV) was significantly decreased than healthy control ((11.26±4.92)μV, P<0.01).In CD group,the amplitude of P3nogo ((5.20±3.17)μV) was significantly reduced than healthy control ((11.26±4.92)μV, P<0.01).Conclusion N2nogo and N2d are associated with the early phases of response inhibition and reflected response conflict.P3nogo and P3d are associated with the late phases of response inhibition and monitored inhibitory control.These data suggest that CD+AP participants exhibited im-paired response conflict and inhibitory control.This may be associated with persistent antisocial behavior.
