The expression of specific genes in sex chromosomes is the basis of sex-specific membrane protein in mammalian spermatozoa. The gene expression products are shared among spermatozoa through intercellular bridges, however, the phenomena of male transmission-ratio distortion and sex ratio distortion proved that differential proteins exist between X and Y spermatozoa. In addition, the existence of sex-specific proteins was confirmed by the separation experiment of X/Y chromosome bearing spermatozoa and the detection result of sex specific proteins. At the same time, it was also confirmed that the difference of the sex-specific protein is weak . The advance of separation techniques as well as the integration and optimization among these techniques has made it possible to separate sex-specific membrane proteins in mammalian spermatozoa.

Objective To investigate the significance of serum neuron specific enolase (NSE) in the severity and prognosis assessments of diffuse axonal injury (DAI).Methods The levels of serum NSE were measured by radioimmunoassay (RIA) at 12 hours and 1st,2nd,3rd,7th and 14th days after injury in 79patients with DAI.The relationship of serum NSE level with the severity and the prognosis of DAI were analyzed in the patients with DAI.Another 15 patients with only limb fracture and without hemorrhagic shock treated in the hospital during the same period served as the control group.Results The serum NSE levels of the mild injury group were (10.47 ± 2.75) ng/L,(13.41 ± 3.45) ng/L,(16.41 ±4.14) ng/L,(15.57 ±4.28) ng/L,(7.95 ±2.79) ng/L,and (6.39 ± 1.55)ng/L at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.The serum NSE levels of the moderate injury group were (14.98 ± 3.78) ng/L,(19.88 ± 4.78)ng/L,(22.41 ±5.50) ng/L,(20.11 ±6.60) ng/L,(14.59 ±6.64) ng/L,and (8.31 ±3.83) ng/L respectively at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.While the serum NSE levels of the severe injury group were (27.22 ± 4.54) ng/L,(36.43 ± 10.38) ng/L,(41.32 ± 12.44) ng/L,(43.98 ±9.51) ng/L,(42.22 ± 13.05) ng/L,and (37.59 ± 12.96) ng/L at 12 hours and 1st,2nd,3rd,7th and 14th days after injury respectively.The NSE levels in each time point were significantly higher in the severe injury group than in the mild and moderate injury groups (F within =28.11,P ＜ 0.001 ; F between =57.34,P ＜0.001 ;F interaction =8.21,P ＜ 0.001 ;P ＜ 0.01).Compared with the control group ((6.26 ± 1.35) ng/L),the serum NSE levels of the DAI group were significantly different at 12 hours after injury ((18.16 ± 3.76)ng/L,t =2.938,P ＜ 0.01).At three months after injury,patients were divided into the decreased group (n =9),poor prognoses group (in vegetative state or severely disabled,n =29) and good prognoses group (moderately disabled or completely recovered,n =41) according to the GOS score.The serum NSE levels of the decreased group were (32.07 ± 5.73) ng/L,(43.12 ± 15.04) ng/L,(48.26 ± 14.89) ng/L,(50.47 ±11.05) ng/L,(52.90 ±3.82) ng/L,and (56.17 ± 14.62) ng/L respectively at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.The serum NSE levels of the poor prognoses group were (21.90 ± 4.95) ng/L,(24.13 ± 9.94) ng/L,(26.43 ± 6.99) ng/L,(21.62 ± 9.77) ng/L,(15.80 ± 7.15) ng/L,and (10.16 ± 2.33) ng/L respectively at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.The serum NSE levels of the good prognoses group were (13.61 ±4.56) ng/L,(13.75 ±5.10) ng/L,(14.77 ±5.41) ng/L,(13.47 ±4.49) ng/L,(8.92 ± 5.61) ng/L,and (6.60 ± 2.30) ng/L at 12 hours and 1 st,2nd,3rd,7th and 14th days after injury respectively.At each time point,the serum NSE levels were significantly different in the decreased group than in the good prognoses and the poor prognoses groups (F within =18.70,P ＜ 0.001 ; F between =62.97,P ＜0.001 ;F interaction =11.83,P ＜0.001).Conclusion The serum NSE levels can be regard as an index for judging the injury severity and prognosis of DAI,and can be used to guide the option and adjustment of therapeutic approaches for patients with DAI.

OBJECTIVETo explore the theory of "Fei and Dachang being interior-exteriorly related" and the pathogenesis of lung injury by observing changes of inflammatory cytokines and oxygen free radicals in ulcerative colitis (UC) rats.

METHODSTotally 50 healthy male Wistar rats were randomly divided into two groups, the normal control group and the model group, 25 rats in each group. The UC model was established by allergizing colon mucosa combined with TNBS-alcohol (50%) enema. Another 25 rats were recruited as the normal control group. At week 2 and 4 after modeling, the pathomorphological changes of the lung were observed. Furthermore, the contents of tumor necrosis factor alpha (TNF-alpha) and IL-1beta were determined by ELISA. The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluated with colorimetry.

RESULTSCompared with the normal control group, the pathomorphology of the lung tissue in the model group appeared abnormal at week 2 and 4. Compared with the normal control group, levels of TNF-alpha, IL-1beta, and MDA in the lung tissue significantly increased in the model group (P < 0. 01) and the activities of SOD significantly decreased (P < 0.05, P < 0.01).

CONCLUSIONTNF-alpha, IL-1beta, SOD, and MDA might be common material bases for the large intestine involved in lung disease of UC patients, thus providing a modern scientific basis for the theory of Fei and Dachang being interior-exteriorly related.

OBJECTIVETo observe the clinical effect of acupuncture on acute heart failure (AHF) patients.

METHODSTotally 60 patients who were diagnosed as AHF were assigned to the acupuncture group and the control group, 30 in each group. Those in the control group received inotropic agents, preload and afterload reducing therapy, anti-infection and so on. Besides, those in the acupuncture group received needling at relative points, once daily for 5 consecutive days. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SI), left ventricle working index (LCWI) were monitored by thermodilution pulse-indicated continuous cardiac output (PiCCO) technique. Changes of the aforesaid data were compared between before and after treatment. The ICU length of stay, readmission rate,and the 28-day mortality were also compared between the two groups.

RESULTSAfter 5 days of the treatment, CI, SI, and LCWI increased more obviously (P < 0.01), HR and MAP decreased significantly (P < 0.05). Of them, CI, SI, and LCWI increased more obviously in the acupuncture group (P < 0.05).There was no obvious difference in HR or MAP between the two groups (P > 0.05). Compared with the first day of admission in the same group, CI, SI, and LCWI obviously increased in the acupuncture group from the second day (P < 0.05). HR started to decrease since the fourth day (P < 0.05), and MAP began to decrease until the fifth day (P < 0.05). CI, SI, and LCWI started to increase in the control group from the third day (P < 0.05); HR and MAP both began to decrease since the fifth day (P < 0.05). Compared with the control group, the ICU length of stay was obviously shortened in the acupuncture group (P < 0.05). The readmission rate and the 28-day mortality rate were lower than those of the control group (P < 0.05).

CONCLUSIONThe combination of acupuncture and Western medical therapy might strengthen acute heart failure patients' heart functions, elevate the therapeutic effect, and improve the prognosis.
