Objective To explore the correlation of mimecan/osteoglycin withnuclear factor koppa B(NF-κB) and P53 in peripheral arterial disease (PAD) and PAD combined with type 2 diabetes in the elderly.Methods 120 patients with PAD and 60 healthy controls were enrolled in this study.PAD patients were divided into PAD group (n=60) and PAD combined with type 2 diabetes group (n =60) according to clinical diagnostic criteria.Patients in PAD group were divided into class Ⅰ (n=15),class Ⅱ (n=15),class Ⅲ (n=15) and class Ⅳ (n=15),and patients in PAD combined with type 2 diabetes group were divided to class Ⅰ (n=14),class Ⅱ (n=15),class Ⅲ (n=16) and class Ⅳ (n=15) according to Fontaine's classification.The levels of NF-κB,P53 and mimecan in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA).Results The levels of NF-κB,P53 and mimecan were significantly increased in PAD combined with type 2 diabetes group as compared with PAD and control groups [NF-κB..(32.8±5.3) mg/L vs.(19.8±4.2) mg/L,(26.3 ±4.8) mg/L; P53:(3.4±1.3) mg/Lvs.(2.5±1.1) mg/L,(1.4±0.8) mg/L; mimecan:(16.4 ±0.8) mg/L vs.(10.3±0.8) mg/L,(4.8±0.6) mg/L; all P＜0.05].There were significant differences in the levels of NF-κB,P53 and mimecan in class Ⅰ,class Ⅱ,class Ⅲ and class Ⅳ in PAD group [NF-κB:(20.3±3.1) mg/L,(24.5±3.4) mg/L,(28.2±4.6) mg/L and (34.2±5.3) mg/L; P53:(2.2 ±1.8) mg/L,(2.6±1.8) mg/L,(3.3±1.9) mg/L and (3.7±2.7) mg/L;mimecan (8.9±2.6) mg/L,(12.4±1.8) mg/L,(15.6±1.5) mg/L and (17.7±1.6) mg/L; all P ＜0.05].There were significant differences in the levels of NF-κB,P53 and mimecan in class Ⅰ,class Ⅱ,class Ⅲ and class Ⅳ in PAD group combined with type 2 diabetes group [NF-κB:(25.5±4.2) mg/L,(28.8±3.7) mg/L,(33.4±5.6) mg/L and (38.5±4.7) mg/L; P53:(2.5±1.1)mg/L,(2.9±1.0)mg/L,(3.7±1.2)mg/L and(4.6±1.3)mg/L; mimecan:(11.7±2.4)mg/L,(14.9± 1.8)mg/L,(17.4±2.5)mg/L and(20.7±2.8)mg/L; all P＜0.05].The levels of NF-κB,P53 and mimecan was increased with the aggravation of PAD (all P＜0.05).Conclusions The increased levels of NF-κB and P53 are correlated with the increase in mimecan level and Fontaine's classification.

This study was aimed to compare the effects of acupuncture stimulation on different acupoints, which included LR14-Qimen, ST25-Tianshu, GB34-Yanglingquanand CO11-pancreas and gallbladder (auricular vagus nerve intensively distributed areas) on gallbladder pressure and Oddi sphincter function of guinea pig, in order to discuss acupuncture effect on different acupoints in the regulation of motor function of extrahepatic biliary system. A total of 20 adult guinea pigs of both sexes were randomly divided into two groups, with 10 in each group. The detection was made on changes of Oddi sphincter electromyography and gallbladder pressure before and after acupuncture. A double-hook electrode was implanted into the Oddi sphincter for the detection of Oddi sphincter electromyography. And one small artificial balloon was put into the gallbladder to measure the intrabiliary pressure. After the guinea pig was anesthetized, changes of gallbladder pressure as well as the electromyography frequency and amplitude index of Oddi sphincter of the normal guinea pig were recorded. When the guinea pig was stabilized, acupuncture was given on LR14, ST25, GB34 and CO11 for 1 min. Observations were made on acupuncture effects of gallbladder pressure and Oddi sphincter function of guinea pig. The results showed that after acupuncture on LR14 and ST25, the electromyography frequency of Oddi sphincter was obviously increased compared with before acupuncture (frequency:P < 0.01, amplitude:P < 0.05); the gallbladder pressure was obviously decreased (P < 0.05). After acupuncture on CO11 and GB34, the electromyography frequency and amplitude index of Oddi sphincter were obviously decreased compared with before acupuncture (P < 0.05); the gallbladder pressure was obviously increased (P < 0.01). It was concluded that acupuncture on LR14 and ST25 can obviously inhibit the movement of gallbladder and promote the myoelectricity release of Oddi sphincter. Acupuncturing on CO11 and GB34 can apparently promote the shrinking movement of gallbladder and inhibit the myoelectricity release of Oddi sphincter.

Objective To evaluated the effect of the regional cooperative rescue model implemented on the length of time from first medical contact (FMC) to balloon dilation (B),economic expense and prognosis in patients with acute coronary syndrome (ACS).Methods Patients with ACS (including ST-segment elevation and non-ST-segment elevation) selected from other hospitals within 24 hours after onset were treated with emergency percutaneous coronary intervention.Patients were divided into two groups, regional cooperative rescue group and control group without the regional cooperative rescue model approved.The lengths of FMC-to-B time and Door-to-B time (from arrival at emergency department or OPD to balloon dilation),time required for patients referred to our hospital,cardiac function,averaged hospital costs,average hospital stay,percentage of medication used and a major adverse cardiac event (MACE) were analyzed.Results Mean FMC-to-B time,Door-to-B time,referral time and time consumed to obtain informed consent were significantly shorter [(106±33) min,(31 ±8) min,(62 ±18,8 ±3) min] vs.[(231 ±35) min,(109 ±26) min,(98 ±31) min,(28 ±11) min,respectively] by implementing the regional cooperative rescue compared with control group,and LVEF was increased,and LVED was deceased inregional cooperative rescue group.The mean costs [(44 123.0 ±3 427.0) yuan vs.(51 587.0 ±5 621.0)] yuan,days of hospital stay [(8.7 ±4.1) vs.(13.2 ±6.4)] and percentage of medication used were significantly decreased in the regional cooperative rescue group.The incidence of MACE inregional cooperative rescue group was 6.2％,whereas the incidence in control group was 16.8％.Conclusions The regional cooperative rescue model can improve the prognosis and decrease the FMC-to-B time,the rate of MACE and financial burden in patients with ACS.

Objective:To analyze the clinical characteristics of community acquired pneumonia in hospitalized children with infectious exanthems and to accumulate clinical experience in the diagnosis and treatment.Methods:The data of the community acquired pneumonia patients with infectious exanthems in Oingdao Women and Children′s Hospital were collected retrospectively from September 2013 to August 2020 and the clinical characteristics were analyzed.Results:A total of 455 cases were included, and there were 273 boys(60.0%)and 182 girls(40.0%). A total of 106 cases were grouped into the severe group(23.3%)and 349 cases were grouped into the non-severe group(76.7%). The median age was 16.0(9.0, 42.0)months.The exanthems occurred in day(6.9±5.2)d after the beginning of pneumonia.The duration of exanthems was(6.0±3.1)days.The exanthems was polymorphic and non-specific.The detection rate of influenza B virus was highest, including 91 cases(20.0%), followed by 85 cases of MP infection(18.7%), 50 cases(11.0%)of EBV reactivation infection.The median age, hospitalization time, fever time, exanthems appearance time, exanthems duration and the rate of the rash appears in the second fever course, CRP elevation, PCT elevation, IgE elevation, MP infection and reactivation of EB virus in the severe group were higher than those of non-severe group, and the differences were statistically significant( U=13 467.0, t=6.500, 4.923, 3.098, 2.998, χ2=13.445, 15.391, 8.208, 5.313, 29.839, 13.474, P<0.05). Multivariate logistic analysis showed that poor general conditions, extrapulmonary complications, decreased respiratory tone and recurrent fever accompanied by exanthems were independent risk factors. Conclusion:A non-specific infective rash associated with the course of the hospitalized CAP has some implications for the assessment of severity and etiology.

Objective: To investigate the feasibility and efficacy of the establishment of regional cooperative acute ST-segment elevation myocardial infarction (STEMI) rescue network among the prefectural-level city hospitals in China. Methods: Based on real-time remote electrocardiogram transmission and "120" emergency systems, we established a regional collaborative STEMI treatment network with our hospital as the network unclears including 8 second-class affiliated hospitals of Jiangsu University in 2013. STEMI treatment time, therapeutic effects and economic indexes were compared before (from January 2010 to December 2012, 180 cases, pre-network) and after (From January 2013 to December 2015, 374 cases, post-network) the establishment of the regional collaborative STEMI treatment network. Results: Post establishment of the rescue network, mean first medical contact (FMC) to balloon (FMC-to-B) time, referral time and obtaining informed consent time were all significantly decreased from (191±41), (94±18), (25±9) minutes to (93±19), (53±18), (7±5) minutes, respectively, in comparison with the pre-network era(all P<0.05). There was a trend of prolonged FMC-to-B time in proportion to aging of STEMI patients(trend P<0.05). Three months post discharge, LVEF was higher (55.3%±10.7% vs. 48.8%±12.1%, P<0.05) and LVEDd was lower ((49.1±10.8)mm vs.(51.8±9.2)mm, P<0.05) in the post-network group compared to pre-network group.In-hospital mortality was also significantly reduced post the establishment of the rescue network (2.14%(8/374) vs. 3.89%(7/180), P<0.05). The results also showed that the total costs (42 017(25 069, 75 148)yuan vs.51 030(28 137, 105 861)yuan), days of hospitalization ((9.1±4.5) days vs. (15.3±4.8)days) and percentage of medicine and consumables were all significantly decreased in the post-network group compared to pre-network group(all P<0.05). Conclusion Establishment of the regional cooperative rescue network is feasible among the prefectural-level city hospitals in China. Establishment of such network can improve the prognosis and decrease the FMC-to-B time, the rate of in-hospital mortality and financial burden of patients with STEMI, and serves as an effective strategy to improve the rescue ability for STEMI patients.

OBJECTIVE To clarify whether the thera-peutic effect of escitalopram on depression patients is cor-related with traditional Chinese medicine syndrome types,and to provide a basis for more accurate drug applica-tion.METHODS A total of 235 depression patients were recruited and classified according to traditional Chinese medicine syndrome differentiation into 5 types:liver and qi stagnation(45),liver stagnation and fire transformation(43),liver qi stagnation and spleen deficiency(79),heart and spleen deficiency(20),and liver and kidney deficiency(38).All patients were treated with escitalopram(10 mg·d-1)for eight weeks.The Montgomery Depression Rating Scale(MADRS)and the 17 Hamilton Depression Rating Scale(HAMD-17)were used to score before treatment and 2,4,and 8 weeks after treatment,respectively.RESULTS Compared with before treatment,the MADRS and HAMD-17 scores and remission rates of each syn-drome type significantly improved with increasing medica-tion duration.The MADRS score relief rate of liver and kidney deficiency type was the most significant(69.3%),significantly higher than the other four syndrome types(47.5%-52.6%,P<0.05);The remission rate of HAMD-17 score was significantly higher than that of heart and spleen deficiency(50.7%vs.28.5%,P＜0.05).The remis-sion rate of HAMD-17 score in liver and qi stagnation type(52.2%)was significantly higher than that in liver stagnation and spleen deficiency type(37.0%,P＜0.01)and heart spleen deficiency type(28.5%,P＜0.05).CON-CLUSION Escitalopram may have a more significant therapeutic effect on patients with liver and kidney defi-ciency and liver stagnation depression.This study pro-vides a new approach for the more effective and accu-rate application of traditional Chinese medicine syndrome differentiation in the selection of clinical antidepressants.

With the increasing number of Chinese medical aid and the overseas development of Chinese medicine, acupuncture has spreaded to and the Republic of Guinea and saw develoment. At present, only China Guinea Friendship Hospital and Astatin Hospital have set up Acupuncture Department, which have equipped with basic acupuncture instruments and acupuncture is used as the main treatment method, and acupuncture is a self funded project. There is no acupuncture major in the local education system, neither laws and regulations on acupuncture and moxibustion. Language barrier also makes it difficult for doctors in the two countries to communicate. Thus, it is recommended to consider geographic, diet, and medical factors when formulating acupuncture treatment plans which are suitable for local conditions, and launching new projects such as laser acupuncture treatment and ear concha electroacupuncture treatment, while improving the language level of foreign aid physicians, designing suitable teaching materials, and using multimedia technology for teaching. Besides, we should promote legislation, conduct academic and cultural exchanges, so as to better promote the development of acupuncture and moxibustion in Guinea.

OBJECTIVETo evaluate the effect of new regional cooperative rescue model on the first medical contact-to-balloon time and outcome in patients with ST-elevation myocardial infarction.

METHODPatients with acute myocardial infraction (AMI) and onset time within 24 hours transferred from other hospitals to our clinic and underwent emergent percutaneous coronary intervention (PCI) between January 2010 and January 2013 were included in this study. Patients were divided into two groups: regional cooperative treatment group (n = 230) and control group (n = 168) according to whether the first contact clinic belongs to the regional cooperative rescue model or not. The first medical contact to balloon (FMC-to-B) time, door to balloon (D-to-B) time, referral time, cardiac function, mean cost, days of hospitalization, and major adverse cardiac event (MACE) during the 6 months follow up were compared.

RESULTSMean FMC-to-B time, D-to-B time and referral time were significantly decreased from (212 ± 37), (107 ± 18), (103 ± 23) min (control group) to (98 ± 23), (25 ± 7), (62 ± 12) min respectively in regional cooperative treatment group. Mean medical cost (42 221 (23 184, 77 768) RMB vs. 49 654 (25 126, 122 433) RMB) and days of hospitalization (7 (5, 13) days vs. 10 (6, 20) days) were also significantly lower in regional cooperative treatment group than in control group. At 6 months follow up, LVEF was significantly higher(54.9% ± 8.6% vs. 48.9% ± 9.1%, P = 0.01), LVEDD ((48.9 ± 5.7)mm vs.(51.4 ± 6.0) mm, P < 0.01) as well as MACE rate (7.4% (17/230) vs. 17.9% (30/168) , P < 0.05) were significantly lower in regional cooperative treatment group than in control group.

CONCLUSIONThe regional cooperative rescue model can decrease the FMC-to-B time, improve cardiac function, and reduce both patients' financial burden and MACE in patients with acute myocardial infarction.

BACKGROUNDIntravascular microbubble-enhanced acoustic cavitation is capable of disrupting the vascular walls of capillaries and small vessels. This study was designed to investigate the impact of microbubble-enhanced, pulsed and focused ultrasound (MEUS) on the blood perfusion of subcutaneous VX2 tumors in rabbits.

METHODSSubcutaneous VX2 cancers in twenty New Zealand rabbits were treated by combining high-pressure amplitude, pulsed and focused therapeutic ultrasound (TUS) and intravenous microbubble injections. The TUS transducer was operated with a peak negative pressure of 4.6 MPa and a duty cycle of 0.41%. Controls were subcutaneous VX2 cancers treated with TUS or microbubbles only. Contrast-enhanced ultrasound (CEUS) and intravenous Evans Blue (EB) perfusion were performed to assess the tumor circulation. The tumor microvascular disruption was assessed by histological examination.

RESULTSCEUS showed that the tumor circulation almost vanished after MEUS treatment. The average peak grayscale value (GSV) of tumor CEUS dropped significantly from 84.1±22.4 to 15.8±10.8 in the MEUS-treated tumors but no significant GSV changes were found in tumors in the two control groups. The mean tumor EB content of the MEUS-treated tumors was significantly lower than that of the controls. Histological examination found scattered tumor microvascular disruption with intercellular edema after MEUS treatment.

CONCLUSIONThe tumor circulation of VX2 cancers can be arrested or significantly reduced by MEUS due to microvascular disruption.

OBJECTIVE: To compare the effect difference between acupuncture combined with western medication and simple western medication for Meniere's disease. METHODS: Ninety-six patients with Meniere's disease were randomly assigned into a combination group (48 cases, 12 cases dropping) and a medication group (48 cases, 9 cases dropping). Betastatin mesylate tablets (once 12 mg, 3 times a day) and mecobalamin tablets (once 0.5 mg, 3 times a day) were prescribed orally in the two groups. Acupuncture was used in the combination group, twice a week, 20 min a time, and the acupoints were Baihui (GV 20), Fengchi (GB 20), Tinggong (SI 19), Hegu (LI 4), Quchi (LI 11), Zusanli (ST 36), Fenglong (ST 40), Taichong (LR 3), Taixi (KI 3) and Tianshu (ST 25). All the treatment was given for continuous 12 weeks. The symptoms were observed by dizziness handicap inventory (DHI), tinnitus handicap inventory (THI), pure tone audiometry score and stuffy ear visual analogue scale (VAS). The effects were compared in the aspects of dizziness, hearing and activity. RESULTS: The scores of DHI, THI, pure tone audiometry and VAS scores after treatment were lower than those before treatment in the two groups (all <0.05), with lower scores of the above 4 indexes in the combination group after treatment (all <0.05). The difference values before and after treatment of the 4 indexes in the combination group were higher than those in the medication group (all <0.05). The effective rates of dizziness, hearing and activity in the combination group were 97.2% (35/36), 91.7% (33/36), 88.9% (32/36), which were better than 71.8% (28/39), 74.4% (29/39) and 69.2% (27/39) in the medication group (all <0.05). CONCLUSION Acupuncture combined with conventional medication achieve better effect than simple conventional medication.
