Objective To discuss the problem of upper respiratory tract infection presenting various clinical manifestations in adults thereby likely making misdiagnosis and to put forth the patients with the symptom of acute abdominal pain as examples in order to caution emergency physicians to avoid misdiagnosis and mistreatment.Methods Data of 58 adult patients with upper respiratory tract infection were collected from January 2010 to December 2011.The chief complain of these patients was acute abdominal pain.After analysis of data including clinical history,symptoms and signs,laboratory findings and medication,patients were divided into two groups post hoc:correctly diagnosed group (group A) and misdiagnosed group (group B).In group A,anti-chill medicine such as tylenol cold tablets (a compositus of paracetamol,pseudoephedrine hydrochloride,dextromethorphan and chlorpheniramine) was given to patients,while in group B,anisodamine (muscarine cholinergic blocker) and antibiotics were given instead of anti-chill medicine.The anti-chill medicine such as tylenol cold tablets would be given to patients of group B when abdominal pain was not released 8-48 hours after treatment.The course of treatment and outcome of patients in the two groups were observed.Results Of 28 patients in group A,27 had abdominal pain relieved or disappeared 2-3 hours after treatment and only 1 patient had abdominal pain lasted 12 hours after treatment.Of 30 patients in the group B,only 2 patients presenting the symptom of acute gastroenteritis got totally relived 2-3 hours after treatment,while the rest of 28 patients did not get rid of abdominal pain,or only had brief period of painlessness after anisodamine injection.Alternatively,8-48 hours later as Tylenol Cold Tablets was given to patients of group B,the abdominal pain was relieved or disappeared after 2-3 hours without recurrence in 2-48 hours.Conclusions Upper respiratory tract infection manifests diversely in adults,and acute abdominal pain could be a main clinical manifestation.Anti-chill medicine,such as tylenol cold tablets,has a noticeably therapeutic effect for acute abdominal pain caused by upper respiratory tract infection in adults,while anisodamine injection makes poor efficacy.

Objective To investigate the expression pattern of microRNA (miRNA) in the kidneys of unilateral ureteral obstruction (UUO) rats and to identify specific miRNA related to renal interstitial fibrosis (RIF).Methods Forty-eight male SD rats were divided into two groups:UUO group and sham-operated (Sham) group.Rats were sacrificed at 3,7 and 14 days after operation.Histologic changes were examined by Masson staining.Forty-eight selected miRNAs were examined by stem-loop real-time qPCR.Results At the 3rd day after operation,obstructed kidneys from operation rats showed mild edema in the interstitium and mononuclear cell infiltration.At the 7th day after operation,focal interstitial fibrosis was observed.At the 14th day after operation,fibrosis became more severe.The Sham kidneys showed no pathological changes.At the 3th day after operation,25 miRNAs were differentially expressed.At the 7th day after operation,24 miRNAs were aberrantly expressed,whereas 21 miRNAs were differentially expressed at the 14th day after operation (P＜0.05).Among these miRNAs,miR-132,miR-192,miR-194,miR-29c and miR-203 were consistently up-regulated or down-regulated in a time-dependent manner after operation.There were significantly correlations between the expression of five miRNAs and severity of tubulointerstitial injury (P＜0.05).Conclusions There are at least 20 miRNAs differentially expressed in the process of RIF induced by UUO.There are significantly correlations between the expression of miR-132,miR-192,miR-194,miR-29c and miR-203 and the severity of tubulointerstitial injury.They may be closely related to RIF.A further study is needed.

The relapse rate of lumbosacral pain in the observation group was 12.5%, versus 66.7% in the control group, showing a statistically significant difference (P<0.01). The relapse rate of leg length discrepancy in the observation group was 16.7%, versus 80.0% in the control group, showing a statistically significant difference (P<0.01).
Conclusion: Tuina reduction manipulation can obtain substantial therapeutic effect for leg length discrepancy and lumbosacral pain due to sacroiliac joint subluxation, coupled with a low relapse rate.

Objective To explore whether IL-27 inhibited the pulmonary fibrosis through regulating the expression of TGF-β/Smad signaling pathway in the bleomycin-induced pulmonary fibrosis model. Methods Forty male C57/BL6 mice were randomly divided into normal control group(group A),bleomycin-induced pulmonary fibrosis group(group B),bleomycin+IL-27 group(group C)and bleomycin+IL-27 antibody group(group D) with 10 in each. Five mice in each group were sacrificed on days 7 and 28 after with intratracheal bleomycin. TGF-βR1,Smad1 and Smad3 in right lung tissue were measured by Western Blot. Results 1. In the bleomycin-induced pulmonary fibrosis model,the expression of TGF-βR1 was higher on days 7 and 28,which was inhibited by IL-27. 2. The expressions of p-Smad1 and p-Smad3 were highest in group D on days 7 and 28, but were lower in group C on day 7 than those in group B. Conclusion Exogenous IL-27 might alleviate pulmonary fibrosis through inhibiting the related protein phosphorylation in TGF-β/Smad signaling pathway.

Objective To investigate the correlation between ADAM33 T1, S2 gene polymorphism and Bronchial asthma risk in china. Methods We retrived the relevant published studies about ADAM33 T1, S2 gene polymorphism and bronchial asthma risk. Then we divided the population into Chinese and other Asian population. Odds ratio (OR) of Case group and control group was selected as the effect index. Stata 11.0 software was used to calculate heterogeneity test, ORs and 95%CI of two areas, and gave the forest plot and funnel plot of meta results. Results A total of 27 studies were included in this analysis,18 studies in ADAM33 T1 site were 3881 cases in case group, and 3780 cases in control group;and 14 studies in ADAM33 S2 site were 3222 cases in case group, and 3513 cases in control group. Additive model, dominant model, recessive model of ADAM33 T1 in Chinese had association with the susceptibility of bronchial asthma. The results were OR=1.488, 95% CI:1.002-2.167 in Additive model, OR=1.619, 95%CI:1.059-2.475 in dominant model;OR=2.523, 95%CI:1.910-3.333 in recessive model. Three models of ADAM33 T1 in other Asian country had no association with the susceptibility of Bronchial Asthma. Three gene model of ADAM33 S2 in Asian had no association with bronchial asthma susceptibility. Except ADAM33 T1 polymorphism in recessive model, other mode of T1, S2 had no publication bias in Chinese population. Conclusion There are association between ADAM33 T1 gene polymorphism and bronchial asthma, but ADAM33 S2 gene polymorphism and bronchial asthma have no association in Chinese population.

Objective:To observe the changes of insulin secretion in the early stage of severe scald in rats, and to explore its signal transduction mechanism.Methods:Twenty-four male Wistar rats aged 7 weeks were divided into sham injury alone (SIA) group, sham injury+ BPV (HOpic) (SIB) group, scald alone (SA) group, and scald+ BPV (HOpic) (SB) group using the random number table, with 6 rats in each group. Full-thickness scald of 50% total body surface area was inflicted in rats of SA and SB groups by a 6-s immersion of the abdomen and a 12-s immersion of the back in 94 ℃ hot water. Rats in SIA and SIB groups received sham injuries through immersion of the back and abdomen in 37 ℃ warm water for 6 and 12 seconds respectively. From 0 (immediately) to 2 day (s) after injury, the rats in groups SB and SIB were intraperitoneally injected with the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway enhancer BPV (HOpic) solution (0.5 mg/mL) at the dosage of 0.6 mg/kg once a day, and the rats in groups SA and SIA were intraperitoneally injected with the same volume of dimethyl sulfoxide once a day. At post injury hour (PIH) 72, the tail blood of rats was sampled for measuring fasting blood glucose (FBG) with a glucometer, and the pancreatic tissue samples of rats was harvested for observing the pathological manifestations of islets by hematoxylin-eosin staining, counting the docked granules per 10 μm membrane of islet beta cells and calculating the proportion of insulin vesicles through the observation of the ultrastructure of islet beta cells by transmission electron microscope, and detecting the phosphorylation level of Akt in the pancreatic PI3K/Akt signaling pathway by Western blotting. Data were statistically analyzed with one-way analysis of variance and least significant difference test.Results:(1) At PIH 72, the rat FBG levels in SIA and SIB groups were normal and similar ( P>0.05). Compared with the levels of those two groups, the rat FBG level in SA group was increased significantly ( P<0.01), while the level in SB group showed no obvious change ( P>0.05). Compared with that in SA group, the rat FBG level in SB group was decreased significantly ( P<0.01). (2) At PIH 72, the morphology of rat islets was complete and the islet cells distributed regularly in SIA and SIB groups. Compared with those in SIA and SIB groups, the morphology of rat islets was incomplete, the insulin vesicles in islets were common, the islet cells distributed irregularly, and the cytoplasm of some islet beta cells was lightly stained or translucent in SA group; the morphology of islets in SB group did not change obviously. Compared with those in SA group, the morphology of islets was comparatively complete, the insulin vesicles in islets were less common, the islet cells distributed comparatively regularly, and the lightly stained or translucent cytoplasm of islet beta cells was less in SB group. (3) At PIH 72, the number of docked granules per 10 μm membrane of rat islet beta cells and the proportion of insulin vesicles in SIA and SIB groups were similar ( P>0.05). Compared with those in SIA and SIB groups, the number of docked granules per 10 μm membrane of rat islet beta cells in SA group was decreased significantly ( P<0.01), while the proportion of insulin vesicles was increased significantly ( P<0.01); the number of docked granules per 10 μm membrane of rat islet beta cells in SB group was obviously decreased ( P<0.05), while the proportion of insulin vesicles did not change obviously ( P>0.05). Compared with those in SA group, the number of docked granules per 10 μm membrane of rat islet beta cells in SB group was significantly increased ( P<0.01), while the proportion of insulin vesicles was significantly decreased ( P<0.01). (4) At PIH 72, the phosphorylation levels of Akt in SIA, SIB, SA, and SB groups were 0.91±0.03, 0.98±0.03, 0.78±0.08, and 0.87±0.08, respectively. Compared with that in SIA group, the phosphorylation level of Akt was increased obviously in SIB group ( P<0.05) but was decreased significantly in SA group ( P<0.01), while the level in SB group did not change obviously ( P>0.05). Compared with the level in SIB group, the phosphorylation levels of Akt in SA and SB groups were decreased significantly ( P<0.01). Compared with that in SA group, the phosphorylation level of Akt in SB group was increased significantly ( P<0.05). Conclusions:At the early stage post severe scald in rats, the activity of the pancreatic PI3K/Akt signaling pathway and the function of insulin secretion are reduced. Improving the activity of the pancreatic PI3K/Akt signaling pathway in rats can ameliorate the function of insulin secretion and recover the physiological level of blood glucose.

As national strategic resources,traditional Chinese medicine (TCM) resource is the material basis for the pharmaceutical industry and health services.The high-efficiency utilization of TCM resource is a major strategic issue that realize the resource conservation and environment friendly recycling economy,guarantee the sustainable development of medicine.But currently,on one hand,the wild TCM resource was seriously damaged and in a serious shortage of stock,the cultivation variety was degenerated,the tending of endangered medicinal materials and the development of alternative varieties were faced many problems.On the other hand,the limited resources cannot be effectively utilized,which results in the waste of resources.Therefore,two ecological restricted resources,poria cocos and Chinese gall,were studied for comprehensive utilization of resources to explore the comprehensive exploitation and utilization of TCM resource as well as the pattern of sustainable development.We suggested that TCM resource should be taken into account as a whole for comprehensive utilization.We should especially pay attention to basic research for the sustainable development of TCM resource,discovery of bioactive substance,excavation and transformation for functional components,the use of biotechnology,the product development,the formation and extension of industry chain.So as the comprehensive exploitation and utilization of TCM resources and sustainable development would be realized.

In order to understand the difference and expression of genes in CEK cells before and af-ter baicalin interferes with IBV,further reveal and analyze the mechanism of baicalin interfering IBV replication in CEK cells in vitro.After IBV infected CEK cells for 2 h,9.75 mg/L baicalin liq-uid was added to interfere with CEK cells,which was recorded as the baicalin(H-IBV)group,and three replicate wells were set in the control group and the IBV(IBV)infection group.After 36 h culture,cell samples were collected and subject to transcriptome for sequencing.The results showed that there were 102 differentially expressed genes in H-IBV group compared with IBV in-fection group,among which 48 genes weresignificantly up-regulated and 54 genes were significantly down-regulated.Through functional annotation in GO and KEGG databases,it was found that dif-ferentially expressed genes were mainly annotated in biological processes such as cellular proces-ses,biological regulation,metabolism,and secondary pathways such as viral infectious diseases,signal transduction and interaction.Retinol metabolism pathway,phospholipid transfer to mem-brane,IL-27 mediated signaling pathway,MDA5/RIG-I and Toll-like receptor signaling pathway were significantly enriched in CEK cells,and the production of type Ⅰ interferon and interferon al-pha and the process of antiviral infection were also positively regulated.There were more differen-tial genes enriched in nucleic acid catalysis,immune system,and reaction,and interbiological reac-tion.Through the STRING network interaction map,it was found that most immune-related genes could form a 36-node interaction network centered on IRF7,TLR3 and STAT1.Therefore,com-pared with IBV group,the differentially expressed genes after baicalin treatment were mainly an-notated and enriched in the biological process,and the immune system and response were en-hanced,mainly through the positive regulation of IRF7 in the MDA5/RIG-I receptor signaling pathway and the inhibition of TLR3 signal transduction in the Toll-like receptor signaling path-way.Positive regulation of IL-27 mediated pathway and regulation of JAK-STAT signaling path-way were supplemented by activation of the expression of IRF7,TLR3,STAT1 and other related genes,and interaction with corresponding downstream proteins to promote the expression of IFN-α and regulatory cytokines,coupled with negative regulation of viral(defense)response and viral processes.Thus,baicalin interferes with IBV replication in CEK cells.
