ObjectiveTo observe the effects of Jiangtang No. 3 prescription on inflammatory pathways and insulin resistance-related indicators in rats with type 2 diabetes mellitus （T2DM）， and to elucidate its molecular mechanism in combating diabetes. MethodsA T2DM rat model was established using a high-fat diet combined with intraperitoneal injection of streptozotocin （STZ）. Successfully modeled rats were randomly assigned to the model group， metformin group， and low-， medium-， and high-dose Jiangtang No. 3 prescription groups， and a normal group was also set. Daily gavage was administered for 8 weeks as follows： metformin at 0.1 g·kg^-1·d^-1， Jiangtang No. 3 prescription granules at 1.62， 3.24， 6.48 g·kg^-1·d^-1 for the respective dose groups， and sterile water for the normal and model groups. Rat body weight， fasting blood glucose （FBG）， oral glucose tolerance test （OGTT）， and insulin tolerance test （ITT） were measured. After drug intervention， enzyme-linked immunosorbent assay （ELISA） was used to determine serum levels of total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL）， high-density lipoprotein cholesterol （HDL）， non-esterified fatty acids （NEFA）， interleukin （IL）-1β， IL-18， and insulin （INS）. Hematoxylin-eosin （HE） staining was used to observe morphological changes in adipose tissue. Real-time quantitative PCR was used to detect the mRNA expression of Toll-like receptor 4 （TLR4）， nuclear factor-κB （NF-κB）， NOD-like receptor protein 3 （NLRP3）， Caspase-1， IL-1β， IL-18， and gasdermin D （GSDMD） in adipose tissue. Western blot was used to measure the corresponding protein expression levels. ResultsCompared with the model group， Jiangtang No. 3 prescription groups exhibited significantly increased body weight （P<0.05， P<0.01）， significantly reduced FBG （P<0.05， P<0.01）， significant reductions in TC， TG， NEFA， and LDL （P<0.05， P<0.01）， and a significant increase in HDL （P<0.01）. Serum levels of inflammatory mediators IL-1β and IL-18 were significantly decreased （P<0.01）， the homeostatic model assessment of insulin resistance （HOMA-IR） index was significantly reduced （P<0.05， P<0.01）， and adipose tissue pathology was improved. The protein expression levels of TLR4， NF-κB， NLRP3， Caspase-1， IL-1β， IL-18， and GSDMD were markedly decreased （P<0.05， P<0.01）， and the mRNA expression levels of these indicators were also significantly downregulated （P<0.05， P<0.01）. Some effects were superior to those of the positive control drug metformin， and certain indicators exhibited dose-dependent improvements. ConclusionT2DM rats display significant inflammatory responses， disordered glucose and lipid metabolism， and insulin resistance. Jiangtang No. 3 prescription effectively suppresses inflammatory mediators， improves glucose and lipid metabolism and insulin resistance， and ameliorates pathological changes in adipose tissue. Its mechanism may be related to the regulation of the TLR4/NF-κB/NLRP3 signaling pathway in visceral adipose tissue， thereby influencing downstream inflammatory mediators.

This paper analyzed the basic situation of implementing the Law of the People's Republic of China on Traditional Chinese Medicine （abbreviated as Law of TCM） by local regulations based on 30 local laws and regulations. From the perspective of the text of regulations， local regulations mainly refine the relevant provisions of the Law of TCM from the aspects of improving the service system of TCM， training talents of TCM， protecting and developing TCM， and disseminating TCM culture， and carry out innovations based on local conditions. These local regulations can follow the basic concept and value orientation of the Law of TCM， integrate relevant laws and policies to form breakthroughs， attach importance to the feasibility and operability of local legislation， and highlight the local characteristics of TCM. From the perspective of improving supporting legal documents， in the future， it is necessary to increase efforts in strengthening the confidence of TCM culture， deepening the connotation of the development laws of TCM， and optimizing the allocation of TCM management powers.

Objective:This study aims to explore the influence of vowels and sound intensity on formant, so as to provide reference for the selection of sound samples and vocal methods in acoustic detection. Methods:Thirty-eight healthy subjects, 19 male and 19 female, aged 19-24 years old were recruited. The formants of different vowels（/a/, //, /i/ and /u/） and different sound intensities（lowest sound, comfort sound, highest true sound and highest falsetto sound） were analyzed, and pairings were compared between groups with significant differences. Results:①The vowels /a/ and // in the first formant were larger than /i/ and /u/, and /i/ was the largest in the second formant. The minimum value of the first formant is the lowest sound of /i/ and the maximum is the highest sound of /a/. ②In the first formant, the chest sound area increases with the increase of sound intensity, while the second formant enters the highest falsetto and decreases significantly. Conclusion:Different vowels and sound intensity have different distribution of formant, that is, vowel and sound intensity have different degree of influence on formant. According to the extreme value of the first formant, the maximum normal range is determined initially, which is helpful to improve the acoustic detection.

Objective To evaluate the effectiveness of a comprehensive hypertension management. Methods Hypertensive patients aged≥35 years in the Zhengfei community of Zhengzhou were selected. The patients were randomly assigned to the intervention and control groups. Those in intervention group received comprehensive hypertension management from October 2015 to September 2016,whereas those in the control group received the original management mode. Scales to assess blood pressure control, biochemical indexes, unhealthy lifestyle, and cardiovascular disease associated risk level were used to evaluate the effectiveness of the management modes.Results Each study groups had 1 051 patients.There were no significant differences in the baseline data of the two groups (P>0.05). At the end of 1 year of receiving the respective hypertension management modes, each group had 941 patients. Findings revealed that after receiving the comprehensive hypertension management mode, the systolic and diastolic blood pressure in the intervention group decreased by(9.87±7.38)mmHg(1 mmHg=0.133 kPa)and(6.33±4.14) mmHg,respectively.Those in the control group decreased by(7.01±6.02)mmHg and(4.52±3.59)mmHg, respectively,statistically significant differences in the extent of reduction of blood pressure between the two groups (P<0.05). Further, the fasting plasma glucose, postprandial blood glucose, low density lipoprotein, serum creatinine,and microalbuminuria levels in the intervention group were significantly lower than those in the control group(all P<0.05).However,the intervention group exhibited a significant increase in the high density lipoprotein level as compared to the control group(P<0.05).There were no significant differences in the total cholesterol,triglyceride,urinary creatinine levels,and body mass index between the two groups(P>0.05), although they had decreased in both groups. After the 1-year management, these proportions of smoking,heavy drinking,high salt diet and need to exercise were 10.0%,3.7%,20.1%,and 48.9% in the intervention group, and 15.3%, 10.0%, 29.0%, and 54.3% in the control group. The proportions were significantly different between the two groups (P<0.05). After the 1-year management, these proportions of low,moderate,and high risk of cardiovascular disease were 13.3%,33.5%,and 53.2% in the intervention group, and 11.2%, 30.1%, and 58.8% in the control group, respectively, with statistically significant differences between the two groups (P< 0.05). After the 1-year management, the proportion of treated, controlled, and control-treated hypertension using medication was 100%, 65.1%, and 75.3% in the intervention group, and 39.5%, 60.3%, and 70.0% in the control group, respectively, with statistically significant differences between the two groups (P< 0.05). Conclusion The comprehensive hypertension management mode was effective in significantly improving the blood pressure and health condition of hypertensive patients.

The aim of this study was to determine the raising anticancer effects of resveratrol (Res) on paclitaxel (PA) in non-small cell lung cancer (NSCLC) cell line A549. The 10 µg/ml of Res had no effect on human fetal lung fibroblast MRC-5 cells or on A549 cancer cells and the 5 or 10 µg/ml of PA also had no effect on MRC-5 normal cells. PA-L (5 µg/ml) and PA-H (10 µg/ml) had the growth inhibitory effects in NSCLC cell line A549, and Res increased these growth inhibitory effects. By flow cytometry experiment, after Res (5 µg/ml)+PA-H (10 µg/ml) treatment, the A549 cells showed the most apoptosic cells compared to other group treatments, and after additional treatment with Res, the apoptosic cells of both two PA concentrations were raised. Res+PA could reduce the mRNA and protein expressions of COX-2, and Res+PA could reduce the COX-2 related genes of VEGF, MMP-1, MMP-2, MMP-9, NF-κB, Bcl-2, Bcl-xL, procollagen I, collagen I, collagen III and CTGF, TNF-α, IL-1β, iNOS and raise the TIMP-1, TIMP-2, TIMP-3, IκB-α, p53, p21, caspase-3, caspase-8, caspase-9, Bax genes compared to the control cells and the PA treated cells. From these results, it can be suggested that Res could raise the anticancer effects of PA in A549 cells, thus Res might be used as a good sensitizing agent for PA.

BACKGROUND: Excellent Iow-antigenicity xenogeneic biological valve scaffold is the premise of constructing tissue-engineered valve by using which kind of acellular methods.OBJECTIVE: To explore the optimal preparation method of making tissue engineered heart valves by meesuring efficiency of different acellular methods and ability to preserve the matrix.DESIGN, TIME AND SETTING: The prospective randomly controlled study was performed at the Central Laboratory of Taian Central Hospital from January 2007 to June 2008.MATERIALS: Sixteen specimens of porcine aortic valves were randomly divided into control, NaCI-sodium-dodecyl-sulfate (SDS),trypsin and triton-X100 groups.METHODS: Specimens in the control group were left intact. Three test groups were decelluladzed with NaCI, trypsin andTriton-X100 respectively.MAIN OUTCOME MEASURES: The gross structure, optical and electron microscope ultrastructure of the decelluarated porcineheart valve matrix was compared. The expression of vascular endothelial cell major histocompatibility complex (MHC)- Ⅰ antigenwas detected by immunohistochemical method.RESULTS: Treatment with NaCL-SDS achieved only incomplete decellularization. The main components of extracellular matdxwere reserved completely, but the fibrous components became unclear and swelling. Treatment with trypsin removed cellscompletely, but caused serious structural alterations, with the presence of swollen collagen fiber, crude edge, widen and irregularfiber interspace. Treatment with Triton-X100 achieved both complete decelluarization and preservation of the matrix structure.Valves following treatment of NaCI-SDS, trypsin and Triton-X100 had certain immunogenicity. However, the immunogenicity ofvalves following treatment of trypsin and Triton-X100 was significantly lower compared with the treatment of NaCL-SDS.CONCLUSION: The decellularization method by Triton-X100 is effective and complete. The Triton-X100 method does not changematrix structure and has low immunogenicity.
