[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 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 investigate the effects of pregnancy and lactation nonylphenol (NP) exposure on the balance of Treg/Th17 cells in the brain of offspring mice and the related mechanisms.Methods:Thirty pregnant C57BL/6 mice were randomly divided into three groups: control group (drinking distilled water), and NP-treated groups (drinking 0.2 μg/ml or 2.0 μg/ml NP water solution). ELISA kit was used to analyze the levels of TNF-α, IFN-γ and IL-17, flow cytometry was used to analyze the frequency of Treg and Th17 cells in spleen, quantitative RT-PCR was used to analyze the RORγt, Foxp3 mRNA, Western blot was used to analyze the protein expression of RORγt, Foxp3 and PI3K/Akt/mTOR signal pathway, and immunofluorescence was used to analyze the expression of Iba1 in the brain tissue of offspring mice.Results:Compared with the control group, NP exposure increased the serum levels of IL-17 and TNF-α in male offspring mice ( P<0.05), and decreased the levels of IFN-γ( P<0.05). Flow cytometry analysis showed that the percentage of Th17 cells in the spleen of male offspring mice exposed to NP (0.2 μg/ml or 2.0 μg/ml) was significantly higher than that of the control group, while the percentage of Tregs cells was lower. Compared with the control group, the expression levels of Foxp3 proteins in the brain tissue of male offspring mice exposed to NP (0.2 μg/ml or 2.0 μg/ml) was significantly lower, accompanied by a dramatic increase in RORγt protein levels ( P<0.05). Similar mRNA expression was also observed in qRT-PCR analysis. The protein expression levels of mTOR (p-mTOR) and its upstream related regulators[PI3K, p-Akt (Ser473), p-Akt (Thr308)] in the brain of male offspring mice increased gradually during the period of exposure to NP( P<0.05). Immunofluorescence analysis showed that compared with the control group, the number of Iba1 positive cells in brain tissue of male offspring mice exposed to NP (0.2 μg/ml or 2.0 μg/ml) increased significantly ( P<0.05). Conclusions:Maternal exposure to NP during pregnancy and lactation may affect the development/function of neurons in offspring through neuroimmune axis, and increase the risk of neurodevelopmental disorders in offspring.

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.
