BACKGROUND:High-density lipoprotein is related to lipid metabolism, but its function cannot be restricted to the scope of lipid metabolism. Simultaneously, exercise regulation has effects on the activity and amount of high-density lipoprotein, but the optimal movement pattern needs to be studied. OBJECTIVE:To offer the theoretical support for formulating fitness training and prospect the possible direction and reference in fol ow-up studying the biological function and exercise regulation of high-density lipoprotein. METHODS:PubMed database was searched for relevant articles published from 1990 to 2015 using the keywords of“HDL and exercise, HDL and biological function”in English. Final y, 44 articles were included in result analysis. RESULTS AND CONCLUSION:The biological functions of high-density lipoprotein mainly include high-density lipoprotein-mediated metabolism of glucose, protein and fat, anti-inflammation, antioxidation and insulin secretion, and at the same time, we summarize the effects of exercise on the concentration, numbers of molecular and components of high-density lipoprotein. The results indicate that the combination of resistance and endurance training is the best way for raising the concentration and functional effects of high-density lipoprotein.

Objective To find a preferable cryopreservative solution and enhance the viability further.Methods Donor hepatocytes were isolated from hybrid pig weighting 5～8 kg by means of collagenase.Then the hepatocyte suspension was put into a liquid nitrogen container for one month with three different cryoprotectants (only use DMSO,combined use of DMSO+HES and combined use of DMSO+HES+1.3 mmol/L Ca 2+).The samples were thawed rapidly and detected in the viability and morphology after a month.Fractional hepatocytes were cultured five days in containing Ca 2+ and uncontaining Ca 2+ culture media to observe the expression of function.Results Porcine hepatocytes,which were preserved in different culture media,show the different viability and morphology manifestation.Among the total the method of only uses DMSO show worst effect.Then is the DMSO+HES group.Combined cryopreservative method with HES+DMSO+1.3 mmol/LCacl 2 has a best effect and functional expression.Hepatocytes were cultured in culture media containing Ca 2+is better than those were cultured in culture media uncontaining Ca 2+.Conclusion The combined cryopreservative system in which HES+DMSO+1.3 mmol/LCacl 2 as the cardinal component can improve the preservative quality significantly.

Objective To observe the therapeutic effect and prognosis of patients with severe traumatic craniocerebral injury treated by Lund program combined with Angong Niuhuang pill. Methods A prospective study was conducted. Forty-nine patients with severe traumatic craniocerebral injury were divided into two groups:combined treatment group (25 cases) and control group (24 cases). All the patients in the two groups received conventional therapy. Additionally, the combined treatment group was treated by the Lund program combined with Angong Niuhuang pill, the patients after admission into the intensive care unit (ICU), indwelling of gastric tube was immediately given (the tube inserted and retained through mouth in cases with cranial base bone fracture), one pill of Angong Niuhuang was fed nasally twice a day for consecutive 15 days. Before and after treatment, the intracranial pressure (ICP), cerebral perfusion pressure (CPP), Glasgow coma scale (GCS) score, the mean flow velocity of middle cerebral artery (MCA), and the incidence of complication, clinical efficacy and prognosis in the two groups were observed. Results There were no statistically significant differences in the levels of ICP, CPP, GCS score and the average flow velocity of MCA before treatment and the first day after treatment between the two groups. Beginning from 3 days after treatment, the degrees of improvement in the above indexes in the combination treatment group became much better than those in the control group [ICP (mmHg, 1 mmHg=0.133 kPa):16.78±4.50 vs. 18.80±5.67, CPP (mmHg):71.35±1.63 vs. 58.11±1.47, GCS score:9.53±0.38 vs. 8.23±0.44, the mean blood flow velocity (cm/s):152.23±3.33 vs. 178.86±5.23, all P<0.05]. The incidences of complications such as hyperpyrexia [8.0%(2/25) vs. 41.7%(10/24)], hyperspasmia [12.0%(3/25) vs. 45.8%(11/24)] and cerebral hernia [8.0%(2/25) vs. 33.3%(8/24)] in the combined treatment group were significantly lower than those in the control group (all P < 0.05). The rates of renal failure, electrolyte imbalance and pulmonary infection in combined treatment group were also lower than those in the control group, but the differences were not statistically significant (all P>0.05). The rate of good therapeutic effect in combination treatment group was obviously higher than that of the control group [72.0% (18/25) vs. 33.3% (8/24), P < 0.05], while the mortality was markedly lowered [8.0% (2/25) vs. 33.3% (8/24), P < 0.05]. Conclusions The combination of Lund program and Angong Niuhuang pills for treatment of patients with severe traumatic craniocerebral injury can reduce the degree of increase of ICP at early stage, ameliorate cerebral edema and its development, elevate CPP and improve cerebral ischemia and hypoxia. In the aspects of controlling hyperpyrexia, decreasing limbs twitches and the incidence of hernia, elevating the quality of patients' life, reducing mortality and improving prognosis, the therapy has relatively good therapeutic effects.

Dual material gate SOI MOSFET with asymmetrical halo can suppress short channel effect and increase carriers transport efficiency. The analytical model of its subthreshold drain current is derived based on the explicit solution of two-dimensional Poisson's equation in the depletion region. The model takes into consideration the channel length modulation effect and the contribution of the back channel current component. Its validation is verified by comparision with two dimensional device simulator MEDICI.

Objective To investigate whether velocity vector imaging (VVI) combined with stress echocardiography could detect potential myocardial impairment of the left ventricle(LV) in diabetic rats.Methods DM rats ( n = 18,administered by STZ at 65 mg/kg) and control rats( n = 12) were performed with VVI and M-mode echocardiography both at rest and after dipyridamole stress 12 weeks later. Twodimensional echocardiographic cine loops and M-mode images of three consecutive beats were obtained from the short-axis views at the mid-LV level. The means of segmental peak systolic velocity(Vs), circumferential strain(εc) ,radial strain(εr), systolic circumferential and radial strain rate (SRc, SRr) and the percent wall thickening (WT% ,derived from M-mode) were obtained. After echocardiograms were performed,the hearts were excised and prepared for HE staining and ultrastructural observations under electron microscopy.Results At rest,only SRc in the DM group was significantly lower than that in the control group( P ＜0.05), the other parameters were statistically comparable between the two groups. After dipyridamole stress,all VVI values in the DM group were significantly lower than those in the control group ( P ＜0.05).However,there was no significant difference in WT% between the two groups either at rest or after dipyridamole stress ( P ＞0.05). Conclusions The VVI parameters combined with dipyridamole stress are more effective in evaluating potential myocardial impairment of the LV walls in diabetic rats. SRc might be more sensitive indices that can be used to detect myocardial impairment at rest.

Objective To observe the effect of traditional Chinese drug combined with training of musculus quadriceps fexoris on knee osteoarthritis(KOA).Methods70 out-patient clinic KOA patients were divided randomly into the Chinese drug group and control group with 35 cases in each group.The Chinese drug group was treated with Shentongzhuyu medicinal broth PO bid;the control group was treated with Sulindac 0.2 g PO bid.Two groups were combined with the training of musculus quadriceps fexoris,having 10 times per course and 3 courses in total with a 3 days interval between two courses.The therapeutic effect was evaluated with footplate pressure gait analysis and modified JOA marks.ResultsAfter treatment,the effect of the Chinese drug group was superior to the control group(P<0.05),especially 12 weeks post treatment.There maximum weight loading,time integral and weight loading intergral of affected limb of the Chinese drug group significantly improved after treatment(P<0.01),but for the control group,only weight loading intergral improved(P<0.05).ConclusionTraditional Chinese drug combined with training of musculus quadriceps fexoris has better curative effect on the pain and functional disturbance of KOA.

Objective To explore a simple and convenient method of small intestine double contrast examination:small intestine double contrast radiography with air-barium by non-tube fast.Methods 130 cases were randomly divided into study group(67) and control group(63).In study group,the enteric-coated capsules to be full of aerogenic powder,barium and cisapride were taken orally by the patients,while in control group,only barium was given orally,and metoclopramide injected by muscle,then the small intestinal air-barium double contrast examinations were performed.Results In the study group,the effect of examinations was satisfactory,ordinary and no effect in 53,12 and 2 cases respectively,and one patients fell because of swallowing difficulty,the total efficiency was 97.02% and the average examination time was(34.63?16.66) minute.In the control group,the effect of examinations was all ordinary and lasted time was(77.12?32.98) minute.These two methods were of remarkable difference in effect and lasted time in statistics(P

Objective To explore the outcome, recurrence rate and postoperative MRI of the modified microendoscopy discectomy (MED) and the conventional MED. Method A total of 107 patients with disc herniation treated from January 2005 to December 2009 were randomly divided into Group A (54 patients) and Group B (53 patients). The patients in Group A were treated with the modified MED that removed the prominent nucleus pulposus but did not access into the annulus. The patients in Group B were treated with traditional MED that removed the prominent nucleus pulposus and cut annulus fibrosus and removed the nucleus pulposus within the annulus fibrosus. The operation outcome, recurrence rate and lumbar spine MRI were compared for observing the morphological changes of intervertebral disc and its surrounding structures. Results All patients were followed up for 1-4 years ( average 2 years),which showed no recurrence in Group A but four patients with recurrence Group B. According to Japanese orthopedic association (JOA) scoring of low back pain, the efficacy was excellent in 51 patients (94%)and good in three (6%), with excellence rate of 100% in Group A; while the efficacy was excellent in 42 patients (79%), good in seven (13%) and poor in four (8%), with excellence rate of 92% in Group B. Videman semi-quantitative assessment of disc signal showed no significant difference of MRI in aspects of signal intensity, thickness, diameter of the spinal canal in Group A before and after operation but highlighted significant differences in protruding degree,spinal canal diameter and lateral recess diameter. Substantial differences of MRI in aspects of signal intensity, thickness, protruding degree, spinal canal diameter and width were observed before and after operation in Group B. There was no significant difference in spinal canal diameter. Conclusions Both methods have sound clinical efficacy. However, the modified MED procedures take advantages of minimizing the damage of disc structure, maintaining the relative stability of the spine and delaying the disc degeneration, which contributes to lower recurrence rate.
