Objective To observe the clinical efficacy of Dong’s Pushing Epiglottis Cartilage Method for the treatment of children food retention through randomized, parallel and controlled clinical trial.Methods Totally 72 children diagnosed with children food retention were randomly divided into treatment group and control group, 36 cases for each group. Children of the treatment group were treated with Dong’s Pushing Epiglottis Cartilage Method, while children of the control group were treated with acupuncture Four Seam. The clinical symptoms, gastric half-emptying time and antral contraction frequency of the two groups before and after the treatment were compared. Results After treatment, integral of clinical symptom in both groups were obviously improved compared with before treatment (P<0.05), but there was no significant difference between the two groups (P>0.05). After treatment, gastric half-emptying time and antral contraction frequency of the both groups were obviously improved, with significant difference (P<0.05), but there was no significant difference between the two groups (P>0.05). The total effectiveness of the treatment group was 97.2% (35/36) and the control group was 94.4% (34/36), with no significantly difference (P>0.05).Conclusion Dong’s Pushing Epiglottis Cartilage Method has relatively good clinical efficacy for the treatment of children food retention.

A 38-year-old woman presented with a 20-year history of yellow papules and band-like atrophy on the right neck. The lesions developed slowly and were asymptomatic. There was no history of long-term sun exposure or family history of similar diseases. Skin examination revealed multiple irregularly sized yellow papules and plaques on the right anterior neck following cleavage lines, multiple pin cap-sized perifollicular papules on the posterior right neck. Well-defined band-like atrophic patches with fine wrinkling were observed in the whole right neck, giving an aged appearance. The skin of the left neck was nearly normal. Pathological examination of biopsy specimens from the yellow papules showed a normal epidermis, scant lymphohistiocytic and melanophage infiltrates around the vessels in the superficial dermis without solar degradation. The collagen bundles in the mid dermis were slightly thickened and arranged tightly in parallel to the skin surface with the absence of inflammatory infiltrate. Verhoeff-van Giesen's staining confirmed a nearly complete absence of elastic fibers in the mid dermis as well as obvious swelling and breakage of resident scant elastic fibers. Von Kossa's staining was negative. Based on the above findings, the diagnosis was made as unilateral mid-dermal elastolysis.

Objective To analyze clinical and radiological characteristics of intracranial hemorrhage in hematological diseases to improve the recognition of them. Methods Thirty-one clinical data of intracranial hemorrhage cases with hematological diseases were reviewed. The basic diseases, clinical and radiological manifestations, and risk factors of mortality were analyzed. Results Intracranial hemorrhage usually occurred in patients with acute myeloid leukemia (AML) or idiopathic thrombocytopenic purpura (ITP),and 13 and 6 cases, respectively, in this group. Most patients presented with headache, restlessness, nausea,vomiting, conscious disturbance and no localization sign by physical examination. CT or MRI images often revealed focus of errlysis. Compared with CT scan, a higher detection rate of ICH could be realized by MRI scan. The total mortality in this group of ICH patients was 71% (22/31). Fever, white blood cell ＞5×109/L,platelet ＜50×109/L, hyperimmunoglobulinemia and disturbance of blood coagulation were risk factors for ICH of this group of patients. The mortality was higher in patients with no less than 2 risk factors[86.4 % (19/22)vs 33.3 % (3/9)] (x2 = 8.718, P = 0.003). Conclusion ICH is a serious complication for hematological patients. MRI scan is good at improving the diagnosis of ICH. It is of high risk of death in patients with no less than 2 risk factors such as fever, white blood cell higher than 5×109/L, platelet less than 50×109/L,hyperimmunoglobulinemia and disturbance of blood coagulation.

Objective: To examine the impact of heat waves and cold spells on the incidence of hemorrhagic stroke, so as to provide insights into prevention of hemorrhagic stroke. Methods: Data pertaining to the incidence of hemorrhagic stroke in Zibo City from 2015 to 2019 were collected from Shandong Provincial Management Information System for Chronic Diseases and Cause of Death Surveillance, and the meteorological data during the period from 2015 to 2019 were captured from National Meteorological Information Center of China. The air quality index (AQI) was collected from the National Daily Report of Urban Air Quality in China. Heat wave was defined as the highest daily temperature that was no less than the 90th percentile (P90), P92.5, P95 and P97.5 of the highest daily temperature in the warm season for at least 2, 3 or 4 days, and cold spell was defined as the lowest daily temperature that was no more than the P10, P7.5, P5 and P2.5 of the lowest daily temperature in the cold season for at least 2, 3 or 4 days. The effect of heat waves and cold spells on the incidence of hemorrhagic stroke was evaluated using a generalized additive model and described with relative risk (RR) and its 95%CI. Results: A total of 8 844 case with first-onset hemorrhagic stroke were recorded in Zibo City from 2015 to 2019. The lowest daily temperature that was no more than P10, P7.5 or P5 of the lowest daily temperature in the cold season for at least two days, or that was no more than P10 or P7.5 of the lowest daily temperature for at least 3 days resulted a remarkably increased risk of hemorrhagic stroke (lowest RR=1.187, 95%CI: 1.031-1.366; highest RR=1.242, 95%CI: 1.042-1.480), and after adjusting the effect of daily mean temperature, the lowest daily temperature that was no more than P10 or P7.5 of the lowest daily temperature in the cold season for at least two days, or that was no more than P10 of the lowest daily temperature for at least 3 days resulted a remarkably increased risk of hemorrhagic stroke (lowest RR=1.236, 95%CI: 1.009-1.513; highest RR=1.274, 95%CI: 1.023-1.585). However, there was no significant association between heat waves and the risk of hemorrhagic stroke. Conclusion Cold spells may increase the risk of hemorrhagic stroke, while no significant association is examined between heat waves and the risk of hemorrhagic stroke.

ObjectiveToll-like receptors (TLRs) play important role in the progression and tumor immunity of some types of cancer,some research have demonstrated that agonist of TLR3 can trigger apoptosis of cancers.This study was proposed to investigate if Poly(I:C),the specific agonist of TLR3,could impact proliferation or apoptosis of progressive breast cancer cells MDA-MB-231,and to investigate the primary mechanism of the function.MethodsExpression of TLR1-10 mRNA was detected by quantitative real-time reverse transcription-polymerase chain reaction.Cell Counting Kit-8 was used to determine the inhibitory effect of Poly(I:C) on proliferation of MDA-MB-231 cells.Cell apoptosis was assayed by flow cytometry with V-FITC/PI staining.Results First,the toll-like receptors 1-10 were all expressed on MDA-MB-231 cells,while the expression level of TLR8 was lower than that of others.Second,according to the CCK-8,the proliferation of MDA-MB-231 cells was inhibited,but the apoptosis was not affected on the basis of Apoptosis Kit.At last,the mRNA expression of TNF-α、IFN-β and IFN-γ were elevated approximately 20 times after Poly(I:C) stimulation for 6 hours.ConclusionMDA-MB-231 cells express all toll-like receptors on mRNA level,and TLR8 was expressed lower than others.The stimulation of TLR3 with Poly(I:C) can inhibit the proliferation of MDA-MB-231,but had no effect on apoptosis.TNF-α、IFN-β and IFN-γ maybe participate in this process.

Objective To investigate the correlation of cervical cancer and cervical intraepithelial neoplasia with expression level of serum soluble tumor necrosis factor receptor Ⅰ and Ⅱ.Methods A total of 915 recruited women in middle or advanced age were treated in our hospital from January 2015 to January 2017.Participants were assigned to one of five groups:group A (n=432) as control subjects;group B (n 89) diagnosed as cervical intraepithelial neoplasia Ⅰ;group C (n=94)as cervical intraepithelial neoplasia Ⅱ;group D (n=175) as cervical intraepithelial neoplasia Ⅲ;group E (n=125) as cervical cancer.The expression level of serum tumor necrosis factor receptor (sTNFR)was detected by enzyme linked immunosorbent assay.Results The level of sTNFR Ⅰ was much lower in the group A (0.869±0.243)μg/L than in the group B (1.127±0.435)μg/L,C (1.164±0.471)μg/L,D (1.206±0.693)μg/L,and E (1.836± 1.216)μg/L (t =7.782,8.741,8.860,and 15.523,all P＜0.001).The level of sTNFR Ⅰ in the group E was much higher than in the groups B,C,and D (t=5.263,5.077,and 5.684,all P＜0.001).No statistical significance was found in sTNFR Ⅰ level between B,C and D groups.The level of sTNFR Ⅱ was much lower in the group A (1.633±0.402)μg/L than in the group B (1.872±0.526)μg/L,C (1.895±0.402)μg/L,D (1.946±0.604)μg/L,and E (3.192±1.145)μg/L (t=4.824,5.254,7.446,and 23.731,all P＜0.001).The level of sTNFR Ⅱ was much higher in the group E than in the groups B,C,and D (t =10.136,10.501,and 12.216,all P＜0.001).There was no significant difference in sTNFR Ⅱ levels between the groups B,C,and D groups (all P ＞ 0.05).Conclusions Cervical cancer and cervical intraepithelial neoplasia are correlated with level of serum tumor necrosis factor receptors.

Porcine alveolar macrophages (PAMs) represent the first line of defense in the porcine lung after infection with porcine circovirus type 2 (PCV2) via the respiratory tract. However, PCV2 infection impairs the microbicidal capability of PAMs and alters cytokine production and/or secretion. At present, the reason for the imbalance of cytokines has not been fully elucidated, and the regulatory mechanisms involved are unclear. In this study, we investigated the expression levels and regulation of interleukin-1beta (IL-1β) and IL-10 in PAMs following incubation with PCV2 in vitro. Levels of IL-1β and IL-10 increased in PAM supernatants, and the distribution of nuclear factor kappa B (NF-κB) p65 staining in nucleus, expression of MyD88 and p-IκB in cytoplasm, and DNA-binding activity of NF-κB increased after incubation with PCV2, while p65 expression in PAM cytoplasm decreased. However, when PAMs were co-incubated with PCV2 and small interfering RNA targeting MyD88, those effects were reversed. Additionally, mRNA expression levels of Toll-like receptors (TLR)-2, -3, -4, -7, -8, and -9 increased when PAMs were incubated with PCV2. These results show that PCV2 induces increased IL-1β and IL-10 production in PAMs, and these changes in expression are related to the TLR–MyD88–NF-κB signaling pathway.

Objective To explore the associations between vitamin D receptor ( VDR) Fok- Ⅰ and Apa- Ⅰ polymorphisms and myasthenia gravis (MG) in Chinese Han population.Methods Polymorphisms of VDR Fok- Ⅰ and Apa-Ⅰ were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.The frequencies of genotypes and hyplotypes were compared among 286 normal controls and 267 MG patients in different subgroups classified by gender,age of onset,presence of thymoma,and Osserman classification sat maximal severity in the follow-up.The association between the genotypes and maximal severity of MG and short-term glucocorticoid treatment were also investigated.Results There were no significant differences in frequencies of genotypes and hyplotypes of both Fok-Ⅰ and Apa-Ⅰ between MG group and control group,and among subgroups of MG.The Fok- Ⅰ showed no statistical difference between the patients with better and less improvement after short-term treatment of glucocorticoid.The frequency of Apa-Ⅰ alleles in the patients with better improvement (55/186,29.6% ) significantly differed from the less improved group ( 7/48,14.6%,OR = 2.46,95% CI 1.04-10.43,x2 = 4.400,P = 0.036).The patients with the genotype A A/Aa were more likely to improve better after the treatment(48/93,51.6%) than in the worse group(7/24,29.2%,OR =2.59,95% CI 0.98-14.60,x2 =3.858,P= 0.049).Conclusions Alleles and genotypes of VDR-Fok- Ⅰ and Apa-Ⅰ were not found to be related with MG onset and severity.MG patients with VDR-Apa-A allele may have better improvement short-term treatment of glucocorticoid.

Objective To investigate the mechanism of Qinggan-Huoxue recipe in the treatment of alcoholic liver disease by observing its function on alcoholic liver disease rat fibroblast growth factor -21 (FGF21). Methods The rats were randomly divided into the blank group (n=10), the carbon tetrachloride group (n=10), the model group (n=11), the Qinggan-Huoxue recipe group (n=10), the Qinggan recipe group (n=9) and the Huoxue recipe group (n=10). Except for the blank group and the carbon tetrachloride group, the other rats were given 10 ml/kg alcohol, corn oil and pyrazole mixture (4.5 ml: 2 ml: 25 mg), once a day, 0.3 ml/kg carbon tetrachloride olive oil solution (carbon tetrachloride: olive oil =1: 3) intraperitoneally, and twice a week for 12 weeks to prepare the alcoholic liver disease model. In the ninth week, the Qinggan-Huoxue recipe group was treated with 4.75 g/kg of Qinggan-Huoxue recipe, the Qinggan recipe group was treated with 1.5 g/kg of Qinggan recipe, and the Huoxue recipe group was treated with 3.25 g/kg of Huoxue recipe, once a day, and 28 d for continuous administration. The pathological changes of liver tissue were observed by HE staining and Masson staining. The serum levels of AST and ALT were detected in rats. The changes of FGF21 protein and mRNA expression were detected by immunohistochemistry, Western blotting and fluorescence quantitative PCR. Results Compared with the model group, the liver weight and liver body ratio in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group were significantly lower (P<0.01). Compared with the model group, the serum ALT (41.95 ± 26.78 U/L, 46.63 ± 21.00 U/L, 37.57 ± 27.85 U/L vs. 138.34 ± 43.35 U/L), AST (102.74 ± 23.55 U/L, 111.50 ± 21.26 U/L, 83.72 ± 37.57 U/L vs. 257.41 ± 162.31 U/L) in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group significantly decreased (P<0.01 or P<0.05). Compared with the model group, the expression of FGF21 protein (1.19 ± 0.07, 1.24 ± 0.12 vs. 0.92 ± 0.04) in Qinggan recipe group and Qinggan-Huoxue recipe group significantly increased (P<0.05), and the expression of FGF21 mRNA (1.25 ± 0.08 vs. 0.95 ± 0.05) in Qinggan-Huoxue recipe group significantly increased (P<0.05). Conclusions FGF21 plays an important role in the alcoholic liver disease. During the process of liver injury, FGF21 increases continuously. Qinggan-Huoxue recipe can improve the content of FGF21 in the treatment of alcoholic liver disease.
