Objective To understand the prevalence rate of mild cognitive impairment (MCI) and its related factors in community elderly so as to provide evidence for the community intervention. Methods A cross-sectional study was performed in a random sampling of 925 elderly people. Mini-mental state examination (MMSE), activities of daily living (ADL) scale and questionnaire were used for face-to-face interview. Chi-square test and logistic regression analysis were applied in this study. Results The prevalence rate of MCI was 21.1% in elderly people. Female, high age, illiteracy, loss of spouse, lack of exercise, no professional activitives and not doing some work for the descendants were the risk factors for MCI. Conclusions The aging and the low educational level are the risk factors for MCI in the elderly. High self-care ability scores are the protective factors for MCI.

Objective To investigate the expression of high mobility group box 1 (HMGBI) of TLR4 endogenous ligand and distant organ tissue injury after intestine ischemia/reperfusion and drainage of lymph fluid in rats. Methods Twenty-four Sprague-Dawley (SD) male rats (SPF grade) were evenly divided into 3 groups:Sham surgery group,intestine ischemia-reperfusion (I/R) group,and intestine ischemia-reperfusion with drainage of intestine lymph fluid (IR + drainage) group.The injury of distant organs such as lungs,liver,kidney was evaluated;The expression of high mobility group box 1 (HMGBI) of TLR4 endogenous ligand in intestine,lung and liver after the ischemia-reperfusion injury was measured by immunohistochemistry.Result HE stained sections,as well as HMGB1 immunohistochemistry results showed that the injury of ischemia/reperfusion (I/R) group and ischemia/reperfusion (I/R) + drainage group were more severe than that in the sham group.A large number of cells stained in I/R group,indicating that HMGB1 expression increased.The injury in I/R + drainage group was significantly less severe than I/R group.Western blot tests showed that the expression of HMGB1 in jejunum,ileum,liver,lung increased significantly in I/R group after L/R injury.Gray-scale values of HMGB1/β-actin were 0.3145 ± 0.0549、 1.7352 ± 0.3280、1.4443 ± 0.0926、3.1382 ± 0.4202.Lymph drainage significantly alleviated the damage,the expression of HMGB1 were significantly lower (P ＜0.05).Gray-scale values of HMGB1/β-actin were 0.1745 ± 0.0327、 1.1083 ± 0.2098、 1.1862 ± 0.1221、2.1095 ± 0.1993. Conclusion Increased expression of HMGB1 of TLR4 endogenous ligand is associated with intestinal and distant tissue injury during intestinal ischemia-reperfusion injury.Drainage of lymph fluid can block the gutlymph pathway and thus reduce the source of HMGB1 from the intestinal as well as the injury of distant tissue.

TLR4 mediates I/R injury involving endogenous ligands.Interaction of TLR4 with endogenous ligands provides a critical link between tissue damage and activation of the innate immune response.In the early phase of liver,kidney,heart,or lung I/R injury,endogenous ligands are secreted from several kinds of cells,they are recognized by TLR4.Interaction of TLR4 with endogenous ligands,such as HMGB1,seems to be the most important trigger of inflammation and initiates signaling cascades leading to inflammatory and immune responses.Blocking the interaction of TLR4 with endogenous ligands may be useful in clinical management of inflammation and cellular necrosis caused by ischemic insults.

ObjectiveTo observe the efficacy of pricking cupping in treating herpes zoster at acute stage.MethodSixty patients with herpes zoster at acute stage were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by pricking cupping, while the control group was by oral administration of Western medicine. The total effective rate and the improvement of symptoms and pain at different stages were observed afterintervention.ResultThe total effective rate was 90.0% in the treatment group versus 86.7% in the control group, and the difference was statistically insignificant (P>0.05); after the first treatment course, the decreases of symptom score and pain indexin the treatment group were significantly superior to that in the control group (P<0.05); after the second treatment course, there were no significant differences in comparing the decreases of symptom score and pain index between the two groups (P>0.05).ConclusionPricking cupping is an effective approach in treating herpes zoster of the acute stage, as it can produce a comparatively higher total effective rate and also significantly improve the symptoms and pain.

Ovbective To study the perioperative changes in neurohormonal factors and hemodynamics in rheumatic valve disease. Methods Method: The neurohormaonal factors, including catecholamine (CA), angiotesin II (AGII), aldosterone (ALD), atrial natriuretic factor (ANP) and hemodynamics were studies in twenty-four patients with rheumatic valve disease (RVD). 7 congenital heart disease (CHD) as the control group. Results Plasma CA, AGII, ALD and ANP were higher preoperatively in RVD groups than that in CHD group, and significantly rose during cardiopulmonary bypass in RVD groups. Conclusion There is a hyperaldosteronism in patients with mitral valve disease during perioperative period. The high systemic resistance is closely related to significantly high levels of plasma NA and AGII during operation and in the early stage after operation. In patients with mitral valve disease and pulmonary hypertension, most of pulmonary pressure and resistance decrease in the early stage after operation.

Objective To investigate the expressions of Toll-like receptor 4 (TLR4) and high mobility group box 1 (HMGB1) expression on distant tissue during the intestinal ischemia/reperfusion and the effects of ω-3 polyunsaturated fatty acids (ω-3 PUFAs) intervention in rats.Methods Forty-eight Sprague-Dawley male rats,weighing (281.50 ± 22.68) g,were randomly divided into three groups (n =16) after gastrostomy:normal diet (N) group,enteral nutrition (EN) group and EN plus ω-3 PUFAs (PUFA) group.Each group was further divided into lymph drainage (I/R + D) and non-drainage (I/R) sub-groups (n =8 each) according to whether treated with intestinal lymph drainage.All the rats were subjected to 60 min ischemia by clamping the superior mesenteric artery,followed by 120 min reperfusion,while the rats in the I/R + D subgroups were treated with intestinal lymph drainage for 180 min at the same time.Results The interleukin-6 level in lymph in N (I/R + D) group was significantly higher than in the EN (I/R + D) and PUFA (I/R + D) groups (PUFA vs EN vs N:(154.57 ±69.30) ng/L vs (97.58 ±40.34) ng/L vs (85.35 ±23.93) ng/L,P =0.021).Besides,the serum level of HMGB1 in PUFA (I/R + D) group was significantly lower compared to the other 5 groups [PUFA (I/R) vs EN (I/R) vs N (I/R) vs PUFA (I/R + D) vs EN (I/R + D) vs N (I/R + D):(2.95 ± 1.17) μg/L vs (3.86 ±0.99) μg/L vs (4.45 ± 1.73) μg/L vs (1.71 ±1.41) μg/Lvs (2.11±0.56) μg/Lvs (3.13 ±0.79) μg/L,P=0.000],and it also decreased in the PUFA (I/R) and EN (I/R) groups than the N (I/R) group (respectively,P ＜ 0.05).Furthermore,the serum endotoxin level in PUFA (I/R) group was significantly lower compared to the N (I/R) and EN (I/ R) groups[PUFA(I/R) vsPUFA (I/R+D) vsEN (I/R) vs N (I/R):(0.020±0.004) EU/mlvs (0.028 ±0.006) EU/ml vs (0.028 ±0.005) EU/ml vs (0.018 ±0.006) EU/ml,P=0.014].Together the serum tumor necrosis factor-α level in both PUFA (I/R) and PUFA (I/R + D) groups were significantly lower than theEN (I/R),N (I/R) and N (I/R+D) groups [PUFA (I/R+D) vs PUFA (I/R) vs EN (I/R) vsN (I/R) vs N (I/R+D):(12.03 ±6.57) ng/L vs (14.32 ±6.11) ng/Lvs (23.27 ±15.60)ng/L vs (27.42 ± 10.37) ng/L vs (26.87 ± 5.30) ng/L,P =0.013].The jejunum and ileum mucosa in all the I/R groups showed swelling and atrophy and appeared fragile,while the PUFA groups showed less yellow staining and injury than the other two groups (P ＜ 0.05,respectively).In addition,the expressions of TLR4 mRNA in jejunum,ileum,and liver in all the drainage groups were respectively lower than the corresponding non-drainage groups [jejunum:PUFA (I/R) vs EN (I/R) vs N (I/R) vs PUFA (I/R+D) vs EN (I/R+D) vsN (I/R+D):2.32±0.62vs3.08±1.29vs3.50±2.44vs 1.62±0.79vs 1.67±1.11 vs 1.94±0.81,P=0.025; ileum:PUFA (1/R) vsEN (1/R) vsN (1/R) vs PUFA (1/R+D) vsEN (1/R+D) vs N (1/R+D):2.67±1.08 vs 5.22 ± 3.96 vs 6.95 ±4.92 vs 1.70±0.68 vs 1.80±0.29 vs3.68±1.47,P=0.012; liver:PUFA (1/R)vsEN (1/R)vsN (1/R)vs PUFA (1/R+D)vsEN (1/R+D)vsN (1/R+D):5.67 ±1.94 vs 7.50 ±3.89 vs 7.18 ±4.55 vs 1.70 ±0.86 vs 3.90 ± 1.95 vs 4.12 ±2.11,P =0.001],which was consistent with the reduction of HMGB1 and the decrease of nuclear factor-κB activity in intestine,liver,and lung (P =0.000).Conclusions Lymph drainage and ω-3 PUFAs intervention can reduce the production of HMGB1 and inflammation factors,inhibit the expression of HMGB1 and TLR4 mRNA,and thus alleviate distant tissue injury caused by intestinal L/R.

An isatin derivative ofβ-cyclodextrin Schiff base was first synthesized by the condensation reaction between the carbonyl group of isatin and ethylenediamino group of the mono-substituted β-cyclodextrin. The Schiff base ligand was chemically linked to homemade ordered mesoporous SBA-15 silica gel via 3-( triethoxysilyl) propyl isocyanate coupling agent. In this way, a novel isatin derivative of β-cyclodextrin-bonded SBA-15 stationary phase ( ISCDP) was prepared for HPLC. Its chemical and physical parameters were characterized by infrared spectroscopy, mass spectroscopy, elemental analysis, thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy, X-ray diffraction and BET specific surface area analysis. The basic chromatographic property of ISCDP was evaluated by using polar halogenated uracils and disubstituted benzene positional isomers as solute probes in reversed-phase chromatography. ISCDP was also used to enantioseparate twoβ-blocker drugs in polar organic mode and two dansyl amino acids in reversed-phase mode, respectively. The related chromatographic separation mechanism was also discussed. Above studies were expected to provide experimental basis for the practical application of ISCDP in the future. The results showed that the introduction of isatin indole ring could enhanced the reversed-phase chromatographic separation ability of ISCDP for halogenated uracils within 7 min. The new packing also exhibited high stereoselectivity for the position isomers of nitroaniline, aminophenol and benzenediol, in which the para isomers were finally eluted due to strong inclusion interaction between the isatin derivative of β-cyclodextrin ligand and the isomers. Meanwhile, the introduction of isatin indole ring could also improve the chiral separation ability of ISCDP. For example the fast enantioseparations of chiral β-adrenergic blockers and dansyl-amino acids on ISCDP were achieved within 20 min (Rs>1. 3). Obviously, besides hydrophobicity, various synergistic interactions could enhance the separation selectivities of the new stationary phase for chiral and achiral analytes, including dipole-dipole, hydrogen bonding,π-π and inclusion interactions. The ordered pore structure of SBA-15 facilitated to fast and efficient separation and analysis for drugs with good permeability and low mass transfer resistance.
