Objective To investigate the correlation between white matter hyperintensities (WMH)and hyperintense vessel sign (HVS) on fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging(MRI)in old adults and to explore the risk factors and pathogeneses of WMH.Methods We retrospectively collected imaging and clinical data of patients who had received both head and neck CTA and brain MRI within one month at our hospital from 2013 to 2016.The Fazekas visual scale was used to evaluate periventricular white matter hyperintensity(PWMH)and deep white matter hyperintensity(DWMH)in each brain hemisphere.According to the presence or absence of HVS in a cerebra[hemisphere,patients were assigned into an HVS-positive group or an HVS-negative group.Clinical data,PWMH,and DWMH differences were compared between the two groups.Results A total of 271 patients(542 cerebral hemispheres)were included in this study.HVS-positive imaging occurred in 79(14.6％)cerebral hemispheres and negative imaging was observed in 463 (85.4％) cerebral hemispheres.There was a significant difference between the HVS-positive and negative groups in the ipsilateral CIA stenosis(x2 =126.840,P＜0.01).The incidence of ipsilateral severe carotid artery stenosis in the HVS-positive group was 62.0％ (49/79),which was significantly higher than 9.9％ (46/463)in the HVS-negative group.The incidence of moderate-severe DWMH was 65.8％(52/79) in the HVS-positive group,which was higher than 34.8％ (161/463)in the negative group(x2 =34.962,P ＜20.01).Nevertheless,the incidences of moderate-severe PWMH in the two groups were 65.8％ (52/79) and 55.5％ (257/463),respectively,without a significant difference between them (x2 =6.944,P =0.074).After adjusting for age,gender,ipsilateral ICA stenosis,hypertension,diabetes,etc.multivariate analysis suggested that HVS-positive imaging was still an independent risk factor for DWMH(OR =2.653,95％CI:1.489-4.726,P =0.001).Conclusions HVS-positive imaging is an independent risk factor for DWMH in the elderly,but no clear correlation with PWMH is found.It suggests that hypoperfusion is a possible mechanism for the development of DWMH in the elderly.

OBJECTIVETo observe clinical curative effect of cake-separated moxibustion on impaired glucose regulation (IGR) and explore its action mechanism.

METHODSSixty cases were randomly divided into a simple lifestyle intervention group (control group) and a cake-separated moxibustion combined with lifestyle intervention group (observation group), 30 cases in each one. The control group was treated with lifestyle intervention. Based on lifestyle intervention, cake-separated moxibustion at Pishu (BL 20), Weishu (BL 21) and Yishu (EX-B 3) was applied to the observation group. Fast plasma glucose (FPG), two hours plasma glucose after oral glucose tolerance test (OGTT2hPG), fasting insulin (FINS), homa insulin resistance index (HOMA-IR), blood lipid, body mass index (BMI) and waist circumference (WC) were observed in the two groups before and after treatment.

RESULTSAfter treatment, the OGTT2hPG and FPG were both decreased significantly (both P<0.05) in the two groups, compared between the two groups, the differences of FPG [(0.41 +/- 0.42) mmol/L vs (0.05 +/- 0.08)mmol/L] and OGTT2hPG [(0.85 +/- 0.53)mmol/L vs (0.17 +/- 0.19)mmol/L] were both statistically significant. There were no significant changes in FINS, HOMA-IR, blood lipid, BMI and WC in the control group before and after treatment (all P>0.05), but FINS, HOMA-IR levels, triglycerides (TG), total cholest-erol (TC), low density lipoprotein (LDL-C), BMI and WC in the observation group were decreased obviously after treatment (all P<0.05), which had statistical differences between the two groups (all P<0.05).

CONCLUSIONThe cake-separated moxibustion combined with lifestyle intervention can obviously control blood glucose levels, improve insulin resistance and blood lipid levels, decrease BMI and WC.

[ ABSTRACT] AIM:To investigate the antipyretic effect of patchouli oil on lipopolysaccharide ( LPS)-induced fe-ver in rabbits.METHODS:Male rabbits (n=42) were randomly divided into 7 groups according to their body weight and basal body temperature, including control group, model group, western medical positive group, traditional Chinese medical positive group, and high, middle and low doses (2%, 1%and 0.5%) of patchouli oil groups.Subsequently, except the controls, the rabbits were injected with LPS at a dose of 1 mL/kg (2 mg/L) through marginal ear vein to establish rabbit fever model and the rabbits in control group received the same volume of NS.The rabbits in control group and model group were injected with 0.5%Tween-80 0.5 h late, and the rabbits in the other groups were treated with correspoonding drugs. The effect of patchouli oil on the body temperature was observed, and the levels of interleukin-1β( IL-1β) and tumor nec-rosis factor-α(TNF-α) in the serum, and prostaglandin E2(PGE2) and cyclic adenosine monophosphate (cAMP) in the hypothalamus were measured by radioimmunoassay.RESULTS: The body temperature and the levels of IL-1β, TNF-α, cAMP and PGE2 in model group were significant higher than those in control group.Patchouli oil notably inhibited the body temperature in the febrile rabbits.From 1.5 h to 5.5 h after administration, the body temperatures were increased by (1.06 ±1.55), (1.62 ±1.36), (1.38 ±1.22), (0.98 ±0.98) and (0.48 ±0.95) ℃in high patchouli oil group, re-spectively.From 3.5 to 5.5 h after administration, the body temperatures were elevated by ( 1.47 ±0.73 ) , ( 1.15 ± 0.68) and (0.63 ±0.54) ℃ in middle patchouli oil group, respectively.A tendency of downregulation of the elevated body temperatures was observed at every time point after administration in low patchouli oil group.Patchouli oil significantly decreased the levels of TNF-αin the serum and cAMP content in the hypothalamus, and attenuated the elevated tendency of the IL-1βlevel in the serum and PGE2 level in the hypothalamus.CONCLUSION:Patchouli oil evidently has antipyretic effect on LPS-induced fever in the rabbits.The antipyretic mechanism might be related to the inhibition of TNF-αlevel in serum and cAMP content in the hypothalamus.

Objective:To investigate the role of conjunctival impression cytology in the diagnosis of Sj?gren's syndrome (SS) and the immunological factors influencing conjunctival lesions.Methods:A total of 57 patients complaining about dry eye were collected, including 38 patients with primary Sj?gren's syndrome (pSS) and 19 patients with non-SS. Conjunctival impression cytology tests were performed for all patients, and they were scored by the Nelson method. Thirty-one patients with SS underwent serological tests such as autoantibodies, immunoglobulins, and complement. The correlation between the relevant data was compared using the t test and the rank sum test. Results:The Nelson grade ≥2 is the positive cut-off value for the diagnosis of SS. The sensitivity was 68.4%, and the specificity was 89.5%, and the area under the receiver operating characteristic curve (ROC) was 0.767. In patients with SS, there was statistical correlation between the results of conjunctival impression cytology and antinuclear antibody (ANA) ( χ2=4.664, P=0.031), anti-SSA antibody ( χ2=8.58, P<0.01), anti-SSB antibody ( χ2=6.13, P=0.013), anti-SSA-52 antibody ( χ2=6.48, P=0.011), immunoglobulin (Ig)G ( t=-4.344, P<0.01) and rheumatoid factor (RF) ( U=25.0, P<0.01). Conclusion:Con-junctival impression cytology has certain value in the diagnosis of SS and can be used to evaluate conjunctival lesions in SS. Serum ANA, anti-SSA antibody, anti-SSB antibody, anti-SSA-52 antibody, IgG, and RF levels are significantly associated with the degree of conjunctival lesions, and can be considered as an indirect evidence of conjunctival involvement in SS.

Objective To investigate the mechanism of reverse redistribution (RR) on dipyridamole 201Tl myocardial perfusion studies in the patients with coronary artery spasm. Methods Twenty-six patients with coronary artery spasm and presented as RR on dipyridamole 201Tl myocardial perfusion studies were enlisted as RR group, while other 16 patients with no coronary artery stenosis nor RR were enlisted as control group. Dipyridamole test was repeated during coronary angiography. Corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) and TIMI myocardial perfusion grade (TMPG) were measured at RR related and non-RR related coronary arteries before and after dipyridamole infusion respectively.All of the data were analyzed by Student's t-test orχ2-test and correlation analysis. Results Coronary artery angiography showed slower blood flow and lower myocardial perfusion in RR related vessels when compared with non-RR related vessels in RR group, but there was no significant difference among the main coronary arteries in control group. The perfusion defects of RR area at rest were positively related to slowerblood velocity at corresponding coronary arteries ( r = 0.79, t = 10.18, P ＜ 0.001 ). In RR related vessels,CTFC were (36 ±6) frames and (26 ±7) frames (t =4.15, P ＜0.01 ), while TMPG were (2.02 ±0.39)grades and (2.92 ± 0.12) grades ( t = 2.25, P ＜ 0.05 ) before and after dipyridamole infusion, respectively.In non-RR related vessels, CTFC were (29 ±7) frames and (25 ±5) frames (t =2.31, P ＜0.05), while TMPG were (2.56 ± 0.31 ) grades and (2.96 ± 0.06) grades ( t = 2.17, P ＜ 0.05 ) before and after dipyridamole infusion, respectively. However, there were no significant changes of CTFC and TMPG before and after dipyridamole infusion in control group ( t = 0.932, 0.867, respectively, both P ＞ 0.05 ). Conclusion RR is related to the decreased blood flow and myocardial perfusion induced by coronary artery spasm at rest,which may be improved by stress test such as intravenous dipyridamole infusion.
