Objective To explore the related risk factors and control measures for senium patients with type 2 diabetes and to provide basis for making control and prevention measures.Methods A retrospective case-control study was conducted.548 cases of type 2 diabetes patients in our hospital were selected as case group and other 640 cases of normal people who accepted physical examination in our hospital were selected as control group.Results Exposure rates of smoking,drinking,obesity,hypertension,hypedipidemia and family history in case group were obviously higher than those of control group(P ＜0.05).Conclusion Smoking,drinking,obesity,hypertension,hyperlipidemia and family history were risk factors of type 2 diabetes.Comprehensive intervention measures related to the risk factors,such as maintaining a good way life,were importantto prevent and control type 2 diabetes.

Objective To observe the suppressing effect of topical nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids on ultraviolet ray (UV)-induced erythema.Methods A solar simulator and an UV phototherapy device were used as light sources,respectively.Erythema reaction was induced on the back skin of 30 healthy volunteers by 1,2 and 3 minimal erythema doses (MED) of irradiation.Five preparations including butyl flufenamate 2.5％ ointment,butyl flufenamate 5％ ointment,the base of butyl flufenamate ointment,halometasone ointment,and diclofenac 1％ ointment,were applied to the irradiation sites respectively half an hour before or immediately after the irradiation.One irradiation site remained untreated and served as the control.The degree of erythema was evaluated by a chromameter at 4,24,and 48 hours after the irradiation.Intragroup and intergroup comparisons were done by t test and analysis of variance,respectively.Results When applied half an hour before solar-simulated irradiation,both 2.5％ and 5％ butyl flufenamate ointment totally suppressed the erythema reaction induced by 1-3 MED of UV irradiation,with no significant increase in erythema index at all the three time points after irradiation (all P ＞ 0.05); diclofenac 1％ only inhibited the erythema induced by 1 MED of UV irradiation at 4 and 48 hours,with no difference observed in erythema index between the baseline and these time points after irradiation; however,halometasone significantly aggravated the erythema reaction (P ＜ 0.05).Neither NSAIDs nor corticosteroids applied immediately after solar-simulated irradiation showed statistical effect on the degree of UV-induced erythema.When applied immediately after irradiation using the phototherapy device,butyl flufenamate 2.5％ ointment,butyl flufenamate 5％ ointment and halometasone ointment all induced a significant reduction in erythema reaction at 4 hours after 1 MED of irradiation (all P ＜ 0.05),and diclofenac caused a statistical decrease in erythema reaction at all the time points after 1-3 MED of irradiation (all P ＜0.05).Conclusions Topical use of butyl flufenamate before UV irradiation can effectively inhibit erythema reaction induced by 1-3 MED of irradiation.When applied immediately after irradiation,diclofenac shows the strongest erythema-suppressive effect,followed sequentially by butyl flufenamate and halometasone.

Objective Acute respiratory dysfunction (ARD) can occur after aortic surgery with the use of cardiopulmonary bypass and deep hypothermic circulation arrest, but relatively little is known about acute respiratory dysfunction in the patients with type A aortic dissection. This study aims to analyze the independent risk factors of acute respiratory dysfunction after A type aortic dissection surgery and to assess possible prevention and treatment option in the future. Methods Clinical data of the 252 patients including 193 male patients and 59 female patients who underwent type A aortic dissection surgery from February 2009 to October 2010 were collected. The mean age was 47 years. Postoperative acute respiratory dysfunction was defined as oxygenation impairment (PaO2/FiO2 ＜ 150) that occurred within 72 h of surgery except pleural effusion, cardiogenic pulmonary edema, pneumonia, pulmonary embolism and haemato-/ pneumothorax. There were 187 acute A type aortic dissection patients and 65 chronic type A aortic dissection patients. Clinical characteristics including age, gender, weight, height, history of hypertension, history of smoking, preoperative complications such as preoperative shock and acute renal failure, pericardial effusion, previous cardiac surgery, time from event to surgery, malperfusion syndrome, cardiopulmonary time, cross-clamp time,deep hypothermia circulation arrest time, surgical procedure, duration of intensive care unit stay and postoperative complications including tracheotomy, dialysis dependent renal failure and hospital mortality were gathered. Arterial blood analysis, chest X ray, ventilator parameters, number of blood transfusion and flood balance were assayed after operation. All the factors were evaluated by means of univariate and multivariate logistic regression analysis to identify relative risk factors of ARD. Results Acute respiratory dysfunction occurred in 32 (12.7% ) patients. The in-hospital mortality was significant difference between acute respiratory dysfunction group and non- acute respiratory dysfunction group (P ＜ 0.05). The value of BMI, incidence of acute aortic dissection, preoperative SBP level, cardio-pulmonary bypass time, aortic clamp time and total arch replacement in acute respiratory dysfunction group were significantly higher than the values in non- acute respiratory dysfunction group. Multivariate Logistic regression analysis showed blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes were independent risk factors of early stage acute respiratory dysfunction after type A aortic dissection surgery.Conclusion Acute respiratory dysfunction after type A aortic dissection was a severe early stage postoperative complication and was associated with in-hospital mortality. The patients in acute aortic dissection were prone to have acute respiratory dysfunction. The independent risk factors of acute respiratory dysfunction included blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes.

Objective To investigate the effect of fusidic acid cream on inflammatory reaction caused by skin barrier damage.Methods Eight male SKH-1 hairless mice were included in this study.The back of each of these mice were equally divided into six regions measuring 1 cm × 2 cm in size,which were then assigned into six groups:blank control group remaining untreated,barrier-impaired group,barrier-impaired and fusidic acid-treated group,barrier-impaired and vehicle-treated group,barrier-unimpaired and fusidic acid-treated group,barrierunimpaired and vehicle-treated group.Stratum corneum was removed by adhesive tape stripping to establish an animal model of acute skin barrier damage in the corresponding skin regions of these mice,and fusidic acid cream or vehicle was topically applied to the corresponding regions once.Twelve hours later,skin surface swab samples were collected from the back of these mice followed by bacterial culture and colony counting.Mice were then sacrificed,and skin tissue specimens were resected from these mice,and subjected to real-time fluorescence-based quantitative PCR for the measurement of the mRNA expressions of myeloid differentiation factor 88 (MyD88),interleukin-1α (IL-1α),IL-6,epidermal antibacterial peptides S100a8 and S100a9.Statistical analysis was carried out by repeated-measures analysis of variance (ANOVA) and least significant difference (LSD) test.Results The mRNA expressions of MyD88,IL-1α,IL-6,S100a8 and S100a9 were all significantly higher in the barrier-impaired group than in the blank control group (all P ＜ 0.05).Specifically,the mRNA expression level of MyD88 in the barrier-impaired group was 8 times that in the blank control group (8.3 ± 3.0 vs.0.8 ± 0.4).Compared with the barrier-impaired group,the barrier-impaired and fusidic acid-treated group showed a significant decrease in the mRNA expressions of IL-1α (2.8 ± 0.3 vs.20.1 ± 10.0,F =47.11,P ＜ 0.01),IL-6 (1.6 ± 2.3 vs.9.4 ± 4.0,F =16.18,P＜ 0.01),S100a8 (1.5 ± 1.4 vs.5.0 ± 1.6,F=59.71,P＜ 0.05) and S100a9 (1.2 ± 0.7 vs.3.4 ± 1.6,F=21.94,P ＜ 0.05).Conlusions Fusidic acid cream could attenuate the inflammatory reaction caused by acute skin barrier damage,which might partly explain its action mechanism in the treatment of inflammatory skin diseases.

Objective To investigate the protect effects of Edaravone(Ed)and GM1 on the rat model of parkinson disease(PD).Methods To establish the unilateral PD rat model,6-OHDA was injected at two points of right substantial nigra pars compacta(SNC),ventral tegmental area(VTA),then the old rats were randomly divided into normal,NS,PD,PD + GMI,PD + Ed,FD + GM1 + Ed six groups.14d later,a rotational test induced by apomorphine was performed to determine the successful ratio.Cell apoptosis in SNC of rats were examined by TUNEL methods.Results Normal and NS groups unappeared rotate action by APO,and have no cell apoptosis in SNC.The other groups all appear rotate action(＞7 r/min)by APO,rotate action were in following gradation:PD +GM1 + Ed group(8.0±0.3)＜PD + Ed group(12.0±0.6)＜PD + GM1 group(17.0±1.0)＜PD group(23.0±1.3)(P＜0.01);and cell apoptosis in SNC were in following gradation:PD + GM1 + Ed group(27.63±2.38)＜PD + Ed group(38.42±3.54)＜PD + GM1 group(49.36±3.12)＜PD group(62.61±4.03)(P＜0.01).Conclusion 6-OHDA could induce change of action of rat and cell apoptosis in SNC.GM1,Ed reduce significantly the effect induced by 6-OHDA.GM1 combining with Ed have the best effects.

Flavonoids are natural products that are ubiquitous in the natural world, with wide physiological activities and low toxic and side effects. In recent years, their anti-tumor effect has caused widespread concern and studies. According to the findings, flavonoids have prominent effects in preventing and treating lung cancer, breast cancer, colon cancer, prostate cancer, liver cancer, leukemia, ovarian cancer, gastric cancer and so on. Their anti-tumor mechanisms mainly include anti-oxidation, anti-free radical, induction of apoptosis of cancer cells, impact on cell cycle, immune regulation, inhibition of tumor angiogenesis, inhibition of COX-2, inhibition of telomerase activity and so on. This article focuses on the advance in domestic and foreign studies on anti-cancer activity and mechanism of flavonoids, in order to provide theoretical basis and research ideas for the further development and clinical application of flavonoids.

OBJECTIVESTo study perioperative inflammatory response status in patients with acute aortic dissection. To analyze the reason and outcome of the inflammatory activation.

METHODSBetween August 2011 and December 2011, 30 patients (22 male and 8 female, mean aged (43 ± 9) years) had undergone open repairs of aortic dissection or aneurysm with deep hypothermic circulatory arrest. Indications for surgical intervention were type A aortic dissection in 26 patients and aortic aneurysm in 4 patients. In detail, ascending aorta and arch replacement combined with stent elephant trunk were done in 29 patients, arch replacement combined with stent elephant trunk in 1 patient. According to the time from clinical onset of the dissection to operation, acute group (less than 7 days, group A) 20 patients, chronic group (more than 30 days and aortic aneurysm, group C) 10 patients. White blood cell, C-reactive protein and procalcitonin were assayed before and after operation. These valuables were recorded and compared statistically between two groups.

RESULTSThere were no significant differences in age, operation time, and blood transfusion volume (P > 0.05). Preoperative serum level of inflammatory indicators in group A were significant higher than in group C (t > 3, P < 0.05). Postoperative serum peak level of these indicators were significant higher than preoperative level in both groups (t > 4, P < 0.05). There were much more complications occurred on patients in group A (21 cases) than in group C (0 cases). The occurrence of early postoperative complications in group A was much higher than group C (χ(2) = 12.209, P = 0.000). Mechanic ventilation time in group A and group C were (35 ± 58) hours and (18 ± 9) hours respectively. ICU length of stay in two group were (49 ± 61) hours and (33 ± 12) hours, respectively. The patients with mechanic ventilation time more than 24 h, ICU length of stay more than 5 days in group A was more than in group C significantly (χ(2) = 5.161, P = 0.010; χ(2) = 3.657, P = 0.024).

CONCLUSIONSAcute aortic dissection and surgical procedure induce an acute phase inflammatory reaction. The patients with acute aortic dissection involved more serious organic injury and worse outcome following surgery compared with chronic aortic dissection.

Objective To investigate the effect of hyperacute intensive antihypertensive treatment on the prognosis of intracerebral hemorrhage in basal ganglia region. Methods From January 2013 to December 2015,100 patients with intracerebral hematoma in basal ganglia region (onset ≤3 h)at the Neurological Intensive Care Unit,the First Affiliated Hospital of Dalian Medical University were enrolled prospectively. They all randomly received the intensive antihypertensive or standard antihypertensive treatment voluntarily. They were divided into either an intensive antihypertensive group or a standard antihypertensive group according to the random number table (n = 50 in each group). Within 1 h after beginning to treatment,the target systolic blood pressure was controlled in 130 -140 mmHg in the intensive antihypertensive group,the target systolic blood pressure was controlled in 160 -180 mmHg in the standard antihypertensive group,and the target systolic blood pressure was maintained respectively in the following 7 d. Head CT was performed gain at 24 h after treatment. The intracranial hematoma expansion was evaluated. The National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS)were used to
evaluate their prognoses. The differences of the cumulative mortality in both groups were compared at the same time. Results The incidences of hematoma expansion of the intensive antihypertensive group and the standard antihypertensive group were 12. 0% (6/ 50)and 30. 0% (15/ 50)respectively. There was significant difference between the 2 groups (χ2 = 4. 882,P = 0. 027). There were no significant differences in NIHSS scores within or between both groups at each time points (all P > 0. 05). They were followed up for 90 d,no adverse events occurred in both groups. The favorable prognosis rates of the neurological function were 36. 0% (18 / 50)and 18. 0% (9 / 50)respectively in the intensive antihypertensive group and the standard antihypertensive group. There was significant difference between the 2 groups (χ2 = 0. 411,P =0. 043). Kaplan-Meier curves showed that the cumulative mortality at 24 h,within 7 d and 90 d in the intensive antihypertensive group and the standard antihypertensive group were 4. 0% (2 / 50),6. 0%(3 / 50),and 10. 0% (5 / 50),respectively,those of the standard antihypertensive group were 10. 0%(5 / 50),24. 0%(12 / 50),and 30. 0%(15 / 50),respectively. The results of Log-rank test found that there was significant difference in cumulative mortality between the 2 groups (χ2 =6.280,P =0.012). Conclusions The intensive antihypertensive treatment in the hyperacute cerebral hemorrhage is safe and feasible in basal ganglia region. It contributes to improve prognosis of neurological function,and reduce the incidence of hematoma expansion and the 90 d cumulative mortality.
