Objective To investigate the relationship between duration of hypertension and cognitive function in adult hypertension patients.Methods A total of 224 subjects with normal blood pressure were enrolled in group A,and 1 296 patients with poorly controlled hypertension were further divided by the duration of hypertension into group B (≤5 years),group C (6-10 years),group D (11-20years) and group E (＞ 20 years).Face-to-face surveys were conducted in all the subjects by trained physicians using Mini-Mental-State-Examination (MMSE) and Clock-Drawing-Test (CDT).The incidences of cognitive impairment were compared among the five groups and the relationship between duration of hypertension and cognitive function were analyzed by SPSS 18.0 software.Results (1) Compared with the normotensive group,the hypertensive group performed worse in the scores of MMSE,CDTs,the memory type cognitive function and the non-memory type cognitive function (MMSE:Z =-2.585,P =0.010;C DTs:Z =-3.689,P ＜ 0.001 ; memory type cognitive function:Z =-2.718,P =0.007 ; non-memory type cognitive function:Z =-1.994,P =0.046).(2) The incidences of cognitive impairment in the five groups were 3.6％ (8/224),6.6％ (26/393),16.6％ (72/433),19.7％ (55/279) and 33.5％(64/191),respectively.(3) Compared with the group A,the cognitive function was significantly worse in the group E (MMSE:Z =61.314,P ＜ 0.001 ; CDTs:Z =44.642,P ＜ 0.001 ; memory type cognitive function:Z =35.703,P ＜ 0.001 ; non-memory type cognitive function:Z =54.440,P ＜ 0.001).Conclusions Hypertension is a risk factor for the cognitive dysfunction.The incidence of cognitive dysfunction and the severity are positively associated with the duration of hypertension.In those with hypertension over 20 years,the cognitive dysfunction occurs much more obviously.

Using MRS medium, as imitating gastroenteric environments, such as low pH (1.5-4.5) and high bile salt (0.1%~0.4%), the antagonistic properties of Lactobacillus acidophilus were studied. At the same time, the antimicrobial activities on pathogenic E. coli and S. aureus in the intestinal tract and antibiotic tolerance of Lacto-bacillus acidophilus were also studied. The results indicated that Lactobacillus acidophilus survived at pH 2.5 - 4.5 after 6h culture and the living bacterial number could reach 107cfu/mL. One strain even survived at pH 1.5; that living bacterial number were above 106cfu/mL at the 0.1% -0.3% bile salt and a strain survived in 0.4% after 4h culture; that antimicrobial activities to the pathogenic E. coli and 5. aureus were obvious; and that the tolerance to Penicillin and Roxithromycin was medium and power.

Objective To evaluate the clinical results of femoral-deep femoral crossover bypass in the treatment of long-segment unilateral iliac artery occlusive disease.Methods From July 1995 to December 2010,40 patients (28 males,12 females,aged from 66 to 90,with mean age of 73) with comprehensive unilateral iliac-superficial femoral arteriosclerosis obliterans were enrolled in this procedure.All patients suffered from unilateral common iliac,external iliac,common femoral,and superficial femoral arteriosclerosis obliterans.These patients were treated with femoral-deep femoral crossover bypass.Postoperative ankle-brachial index,blood flow velocity and patency rates in 5,7 and 10 years and limb salvage rates in 5,7 and 10 years were evaluated.Results There was no perioperative mortality nor extremity amputation.35 (87.5％ ) patients were followed-up from 1 to 13 years (mean 5.7 y).Anklebrachial index rose from preoperative 0.23 ± 0.10 to postoperative 0.55 ± 0.11 (t =15.91,P =0.000 ).Popliteal arterial velocity rose from preoperative ( 14 ±6) cm/s to postoperative (34 ± 10) cm/s (t =15.63,P =0.000) ; Tibial arterial velocity rose from ( 10 ±4) cm/s to (22 ±7) cm/s (t =15.71,P =0.000).The primary and secondary patency rates were 60.1％,44.3％,25.3％,and 93.5％,86.8％,57.9％ at 5,7 and 10 years,respectively.Limb salvage rates were 97.5％,95％,and 90％,at 5,7 and 10 years,respectively.Conclusions Femoral-deep femoral crossover bypass is safe and reliable in treating certain unilateral iliofemoral occlusive disease,especially for high-risk old patients or those who are not indicated for endovascular therapies or direct aortic approaches.

Professor LI Zhi-dao, according to acupoint selection of syndrome differentiation in TCM basic theory, concluded a new therapy, namely "tonifying three qi" that is mainly based on three acupoints in the Conception Vessel. This method is consisted of Danzhong (CV 17), Zhongwan (CV 12) and Qihai (CV 6) in the Conception Vessel, which could successively nourish clear qi, stomach qi and original qi. In clinic, according to the severity of symptoms of three qi, the acupoints are selected flexibly, which could respectively treat deficiency of heart-lung qi, deficiency of stomach-spleen qi and deficiency of original qi. Some examples are also given in the article.

Objective:To observe the changes in percentages and subsets of invariant nature kiler T (iNKT) cells in adipose and related tissues at different stages of obesity, and analyze the role of iNKT cells during chronic inflammation in adipose tissues in a mouse model of obesity established with high-fat diet.Methods:Changes in mouse body weight, mental state, glucose tolerance and insulin tolerance were recorded. Hematoxylin and eosin (HE) staining was used to observe pathological changes in adipose tissues. Flow cytometry was performed to detect the percentages and subsets of iNKT cells as well as the percentages and subtypes of macrophages. The levels of cytokines in serum samples and the culture supernatants of lymphocytes in adipose tissues were detected with CBA. The expression of related proteins in adipose tissues was detected by Western blot.Results:(1) The volume of adipose cells increased significantly after four weeks of high-fat feeding, but the infiltration of inflammatory cells was not obvious. Significantly increased infiltration of inflammatory cells was observed after 12 weeks of high-fat feeding. (2) High-fat feeding could reduce the percentage of iNKT cells, increase the proportion of iNKT1 subgroup and decrease the proportion of iNKT10 subgroup in adipose tissues. The proportion of iNKT1 subgroup in thymus increased, but that of iNKT2 subgroup decreased. The percentage of macrophages and the proportion of M1 subgroup in adipose tissues increased, while the proportion of M2 subgroup decreased, which were more obvious after 12 weeks of high-fat feeding. (3) High-fat feeding resulted in decreased expression of E4BP4 and arginase-1 (Arg-1) in adipose tissues and increased expression of inducible nitric oxide synthase (iNOS). (4) High-fat feeding significantly increased the pro-inflammatory cytokines and decreased the anti-inflammatory cytokines in mouse serum and culture supernatants of lymphocytes in adipose tissues with more significant changes observed after 12 weeks of high-fat feeding.Conclusions:Increased iNKT1 and decreased iNKT10 in obese adipose tissues might be closely related to the increased M1 polarization and the imbalance of iNKT subsets might be involved in the progression of chronic inflammation in obese adipose tissues.

OBJECTIVETo make out a computerized formula to diagnose eye's signs of blood-stasis syndrome (BSS), and to improve the previous diagnostic methods by naked eyes.

METHODSThe formula was created by detecting and analyzing the changes of eye's signs in 544 patients (261 of non-BSS and 283 of BSS) quantitatively, adopting computer's color scale principle. And the sensitivity, specificity and accuracy of the formula were verified in 382 patients (97 non-BSS and 285 of BSS). The computerized integral was compared with the naked eye integral, and the normal reference value was calculated with percentile.

RESULTSVarious observatory indices of eye's sign were positively correlated with BSS. The specificity of the computerized method was 83.5%, and the diagnostic sensitivity was 89.8%, the accuracy 88.2%, and the correct index 0.733. Comparisons between the computerized integral method and the naked eye integral method showed significant difference in patients of non-BSS or of BSS in various degrees (including mild, moderate and severe) (P < 0.01). The reference value of the naked eye method was below 15.

CONCLUSIONThe computerized formula of eye's signs has higher specificity and sensitivity in the diagnosis of BSS, while the naked eye integral method is proved to be useful.
