OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

Abstract: Objective　To explore the spatial epidemiological characteristics of severe cases hand, foot and mouth disease (HFMD) in Guangxi, China, from 2014 to 2018, and to provide a basis for identifying the high-risk regions as well as the prevention and control of severe cases of HFMD in Guangxi. Methods　Spatial-temporal scanning analysis, global and local spatial autocorrelation analysis were used to analyze the spatial clustering of HFMD. The trend surface analysis was used to evaluate the spatial distribution trend of HFMD. Results　From 2014 to 2018, the incidence and severe case fatality rates of HFMD were 3.89/100 000 and 4.23%, respectively. Monte Carlo scanning analysis showed that the first cluster region was Cenxi City, the second cluster was mainly concentrated in northwest of Guangxi, and the aggregation time was mainly concentrated in April to May and August to October. The global spatial autocorrelation analysis showed that the severe HFMD was significant clustering distribution, and the Moran's I coefficients of the sever cases, severe morbidity and severe case fatality rate were 0.088, 0.118, 0.197, respectively (P<0.05). Local spatial autocorrelation analysis showed that hotspots of severe HFMD cases were concentrated in the southern Guangxi, mainly in Lingshan County. Anselin local Moran's I clustering and outlier analysis indicated that 5 high-high (H-H) clustering regions for fatality were Lingshan, Pubei, Zhongshan, Zhaoping and Pinggui County. There were 6 high-high (H-H) clustering regions for severe incidence rate, namely Lingshan, Qinnan, Lingyun, Youjiang, Bama Yao Autonomous and Pinggui County, and 1 high-low (H-L) clustering region, Cenxi County. The trend surface analysis showed that the overall number of severe cases of death decreased from east or west to the middle, and increased from north to middle, and then decreased to south. Conclusions　Severe HFMD cases in Guangxi have obvious spatial-temporal clustering, and the hop spots are mainly concentrated in southern Guangxi. The prevention and control of HFMD in areas with high incidence of severe cases should be strengthened to reduce the burden of HFMD cases.

Mycotic thoracic aortic aneurysm (MTAA) is a disease that is difficult to treat and often lethal. Open repair has high morbidity and mortality risks; additionally, thoracic endovascular aneurysm repair (TEVAR) often requires innovative techniques.We report the use of an innominate artery chimney endovascular aneurysm repair (ChEVAR) with carotid-carotid and carotid-left subclavian artery bypass for a time-sensitive Salmonella-related MTAA. A symptomatic type 1a endoleak was discovered and promptly and successfully treated. This report shows that the use of innominate artery ChEVAR to treat MTAA is feasible and safe, although the procedure is rarely performed, even in large series. We hypothesize that prophylactic gutter embolization is a feasible option in view of the high endoleak risks in such cases, although further evidence is required to support this.

Objective To study the suppressive effect of knockdown of miR-21 on the U87 human giioma xenograft growth and the possible mechanism. Methods Nude mice bearing U87 human glioblastoma subcutaneously were treated with miRNA-21 anfisense oligonucleotides(AS-miR-21)intratumomlly every 3 d until the observation peded ended.The tumor volume of the mice treated withAS-miR-21 was measured regularly as compared with that in the control untreated mice and in the mice treated with scramble oligonucelotides(ODN).Finally,the tumors were removed from nude mice for the examination.In-sire hybridization and real-time PCR were conducted to detect the miRNA expression of miR-21.The biological charaetedsties of the tumors were evaluated by HE and immunohistochemieal staining, and the cell apoptosis was detected by TUNEL method. Resulls During the observation period,the tumor growth was delayed and the final tumor volume of AS-miR-21 heated group was smaller than that in the control and scramble ODN treatedg roup(F=6-056,P=0.007).The expression of miRNA precursor was knocked down in As-miRNA treated tunlors compared with that in untreated or scramble ODN treated tumors.Histopathological examination exhibited the appearance of degraded malignancy.The expressions of PCNA and MMP-9 were down-regulated while Septin-7 and P21 were up-regulated and apoptotic index was increased significantly (F=141.021,P=000) as well.Conclusion The suppressive effect of anti-miR-21 ODNs on the growth of U87 human glioma xenogratts is significant and miR-21 Call be taken as a candidate for gene therapy ofhuman glioma.

Human defensin is a family of cationic antimicrobial peptides in human being. During the last two decades a series of endogenous alpha-and beta-human defensins have been discovered. They are important components of the first barrier in human's body against the invasion of various microorganisms, and they are thought to play an important role in linking the innate and adaptive defense system of human being. The recent advances in the research of human defensins were reviewed, including their discovery, molecular and genetic properties, expression regulation, and mechanisms of antimicrobial activity. The possibility to produce human defensins via genetic engineering was also discussed. And the application outlook of human defensins in medicine and curing patients infected with antibiotics-resistant microbials was presented.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

OBJECTIVETo investigate the possible roles of adenosine and the cytokines TNF-alpha and IL-10 in the pathogenesis of acute bacterial prostatitis (ABP) in rats.

METHODSForty-eight male Wistar rats were randomly divided into groups A (ABP), B (ABP + theophylline intervention), C (sham) and D (blank control). ABP models were established by injecting Escherichia coli 0157 into the prostate, and those in group B were treated by intraperitoneal injection of theophylline immediately after modeling. At 4 and 14 days, the prostate tissues of the rats were collected for detection of the expressions of TNF-alpha and IL-10 by immunohistochemistry and the concentration of adenosine by high-performance liquid chromatography.

RESULTSAt 4 and 14 days, the concentrations of adenosine were significantly higher in group A ([48.38 +/- 17.27] and [26.54 +/- 11.22] microg/g) than in C ([0.45 +/- 0.25] and [0.46 +/- 0.29] microg/g) and D ([0.41 +/- 0.23] and [0.43 +/- 0.27] microg/g) (P < 0.05), and so were the expressions of TNF-alpha in A (0.23 +/- 0.08 and 0.21 +/- 0.03) than in C (0.07 +/- 0.03 and 0.07 +/- 0.01) and D (0.07 +/- 0.06 and 0.07 +/- 0.06) (P < 0.05), and those of IL-10 in A (0.13 +/- 0.03 and 0.25 +/- 0.01) than in C (0.07 +/- 0.03 and 0.07 +/- 0.03) and D (0.07 +/- 0.01 and 0.07 +/- 0.02) (P < 0.05). Compared with group A, the rats in group B showed significant increases at 4 and 14 days in the severity of inflammation, concentration of adenosine ([86.64 +/- 32.87] and [51.17 +/- 22.96] microg/g, P < 0.05) and expression of TNF-alpha (0.37 +/- 0.08 and 0.32 +/- 0.06, P < 0.05), but exhibited no remarkable difference in the expression of IL-10 (0.12 +/- 0.06 and 0.15 +/- 0.06, P > 0.05).

CONCLUSIONAdenosine may affect the progression of inflammation by regulating the expressions of the cytokines TNF-alpha and IL-10 in ABP rats through the adenosine receptor signaling pathway.
