Objective To evaluate the therapeutic efficacy of acupuncture based on syndrome differentiation for functional dyspepsia (FD), and to explore the plausible action mechanism.Method Seventy-two eligible FD patients were randomized into a treatment group (36 cases) and a control group (36 cases). In the treatment group, the FD patients were divided into four types, liver-qi stagnation, spleen-stomach qi-deficiency, liver-qi affecting stomach, damp-heat accumulated in stomach, to receive acupuncture at the corresponding points based on syndrome differentiation in addition to the basic points including Zhongwan (CV12), Tianshu (ST25), Zusanli (ST36), and Neiguan (PC6); the control group was given Itopride hydrochloride tablets. Before and after intervention, the symptomatic efficacy index and the MOS 36-Item Short-Form Health Survey (SF-36), as well as serum Gastrin (GAS) content were observed in the two groups.Result The total effective rate was 94.1% in the treatment group, significantly higher than 63.9% in the control group (P＜0.01); after intervention, the improvement of symptomatic efficacy index in the treatment group was markedly better than that in the control group (P＜0.01); the improvements of the SF-36 component scores in the treatment group were markedly higher than those in the control group (P＜0.05).Conclusion Acupuncture based on syndrome differentiation can obviously improve the symptoms of FD patients, gastrointestinal function, and the quality of life, which is possibly realized by regulating serum GAS, and thus this treatment protocol is proper to be the optimal protocol in clinic for FD.

OBJECTIVE: To establish an animal model of alcoholic fatty liver (AFL) and to observe the prevention and treatment with New Qinggan Decoction (NQGD). METHODS: Female SD rats were exposed to the mixture of white spirit and corn oil continuously for up to 6 weeks via an intragastric feeding protocol. The pathologic alteration of the liver and the changes of serum lipid were observed, and the effect of NQGD for preventing and treating AFL was studied. RESULTS: Wide hepatic steatosis was induced in model group rats. Serum triglyceride (TG) and total cholesterol (TC) of the model group were higher than those of the normal group (P<0.01). Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of the model group were higher than those of the normal group (P<0.05). In NQGD group, hepatic steatosis was milder than that in the model group, and serum TG, TC, AST, ALT descended significantly as compared with the model group (P<0.01). CONCLUSION: AFL model of rats established by feeding the mixture of white spirit and corn oil is similar to the episode of the human AFL, and is easy to intervene with medicine. NQGD can prevent the occurrence of AFL in this model.

It also had action of alleviating pain. There were no toxic and side effects. Conclusion: (ZSX) had remarkably preventive and therapeutic effects on atrophic gastritis of rats.

Objective To study the feasibility and necessity of radial artery angiolgraphy in advance on transradial coronary intervention.Methods A total of 682 patients undergoing transradial coronary intervention were divided into two groups by random digits table method.Previous radial artery angiography (pre-RAA) group of 341 cases underwent radial artery angiography;post radial artery angiography (post-RAA) group of 341 cases in the guide wire,catheter in resistance immediately for radial artery angiography.The radial artery imaging characteristics were observed and the radial artery related complications were recorded in two groups.Results The ratio of radial artery spasm in post-RAA group was higher than that in pre-RAA group [11.4％(39/341) vs.6.2％(21/341),P=0.015].The ratio of operation failed in post-RAA group was higher than that in pre-RAA group [3.2％ (11/341) vs.0.6％ (2/341),P =0.014].The radial artery perforation rate and postoperative 1-6 months of radial artery occlusion rate increased significantly in post-RAA group,and there was significant difference between two groups (P ＜ 0.05).Conclusion Transradial coronary intervention in advance for radial artery angiography therapy can effectively observe the radial artery morphology,reduce the radial artery related complications.

Objective: To study the effects of CTGF on the periodontal tissue remolding during orthodontic tooth movement. Methods: A mouse model of orthodontic tooth movement was established. The CTGF and NS were injected into the periodontal tissue of the first molar. HE staining, immunohistochemical staining and automatic image analysis system were used to detect the changes of periodontal tissue and the expression of VEGF. Results: The periodontal tissue remolding accompanied the over expression of VEGF during the orthodontic tooth movement. At day 7, the remolding was most active and the expression of VEGF was the highest. CTGF injection induced acceleration of periodontal remolding and up-regulating the expression of VEGF during orthodontic tooth movement, especially at day 7 and day 15 after the orthodontic force were applied. Conclusion: In the mouse model of orthodontic tooth movement, periodontal CTGF injection induces over expression of VEGF and accelerates the periodontal remodeling during orthodontic tooth movement.

Objective: To evaluate the risk factors for contrast-induced nephropathy (CIN) in patients of acute coronary syndrome (ACS) with normal or slightly impaired renal function after percutaneous coronary intervention (PCI).
Methods: A total of 254 consecutive ACS patients with normal or slightly impaired renal function received PCI in the Second Artillery General Hospital from 2013-06 to 2015-06 were retrospectively studied. All patients had eGRF≥60 ml (min?1.73 m2) and they were divided into 2 groups:CIN group, the patients with serum creatinine increased by 0.5mg/dl (44.2μmol/L) or elevated to 25%higher than the baseline, n=23;Non-CIN group, n=231. The basic condition with laboratory tests, operative indexes were recorded and eGRF value were calculated in all patients.
Results: There were 9%(23/254) patients suffered from CIN after PCI. Multivariate regression analysis indicated that emergent PCI (OR=0.370, 95%CI 0.060-2.297), increased plasma level of NT-proBNP (OR=4.209, 95%CI 1.202-14.742) and without pre-operative aspirin administration (OR=7.950, 95%CI 1.108-57.034) were the clinical risk factors for post-operative CIN occurrence.
Conclusion: Emergent PCI, higher plasma level of NT-proBNP and no pre-operative aspirin administration were the risk factors for CIN occurrence in ACS patients with normal or slightly impaired renal function after PCI.

To shorten the cultivation time and reduce the consumption of raw materials for microbial lipid production, oleaginous yeast Rhodosporidium toruloides AS 2.1389 was cultivated using a two-stage culture mode, in which the cell propagation and lipid accumulation were separated. The yeast cells recovered from the propagation culture were re-suspended in glucose solution for lipid accumulation, through which lipid content over 55% of the dry cell weight was achieved, the longer the propagation stage was, the higher the lipid content. Analysis of the lipid indicated that the long-chain fatty acids with 16 and 18 carbon atoms were major components, suggesting that the lipid can be an alternative feedstock for biodiesel production.

The objective of this work is to investigate how dilution rate and carbon-to-nitrogen (C/N) ratio affects lipid accumulation by Rhodosporidium toruloides AS 2.138 9 in continuous culture. Under steady-state conditions, the increase in dilution rate led to the decrease in lipid content and lipid yield. The highest lipid yield and lipid content at D = 0.02 h(-1) were 0.18 g lipid/g sugar and 57.1%, respectively, while the highest lipid productivity and biomass productivity were obtained at D = 0.14 h(-1). The increase in C/N ratio led to the increase in lipid content. The highest lipid content of 38% was obtained at C/N = 237. The highest lipid yield of 0.12 g lipid/g sugar was obtained at C/N = 92. However, the highest lipid productivity of 0.12 g/(L x h) was obtained at C/N = 32. No significant changes were observed in terms of fatty acid composition of the lipid produced under different C/N ratios, and these three fatty acids, palmitic acid, stearic acid and oleic acid, took over 85% in all samples.

Objective:To explore the core competency of doctors in tertiary public hospitals in regions of different income levels in China, and provide reference for promoting such competency and related policy formulation.Methods:Using multi-stage stratified cluster sampling method, 195 tertiary public hospitals in 16 provinces of China were selected from November 2021 to March 2022. 200 doctors were sampled from each hospital. A self-designed questionnaire was used to investigate the status of doctors′ core competencies, as well as the status of their postgraduate medical education and continuing medical education. According to the per capita gross regional product of each province in China Statistical Yearbook 2022, each province was divided into high, middle and low income regions, and the questionnaire data were descriptively analyzed, while χ2 test was used to compare the differences between groups. Results:A total of 32 673 valid questionnaires were collected. There were 12 135 doctors (37.14%) in China who had received comprehensive education and training of core competency in all dimensions. Among the dimensions of self-rated core competency of the surveyed doctors, there were 10 019 doctors (30.66%) with insufficient teaching ability and 438 (1.34%) with insufficient professional quality, and there was no significant difference between regions ( P>0.05). There were 2 385 (27.08%), 2 528 (27.55%) and 3 646 (24.82%) doctors in high-, middle- and low-income regions with insufficient lifelong learning ability, respectively. The proportion of doctors in middle- and high-income regions was higher than that in low-income ones ( P<0.05). There were 1 317 (15.57%), 1 290 (14.06%) and 2 719 (18.51%) doctors with insufficient knowledge and skills in high-, middle- and low-income areas, respectively. The proportion of doctors in low-income regions was higher than that in middle- and high-income regions ( P<0.05). The proportion of doctors who did not receive any kind of postgraduate medical education or continuing medical education in low-income regions was 7.33% (1 077 people), higher than that in high-income and middle- income ones ( P<0.05); 50.44% (4 442 people) of surveyed doctors in high-income regions believed that for standardized training of resident physicians (hereinafter referred to as residential training), the clinical teachers were " overworked to take this job", which was higher than that in middle- and low-income regions ( P<0.001); In middle-income regions, 46.16% (4 235 people) and 43.46% (3 987 people) believed that the salary residents and specialized physicians in standardized training (hereinafter referred to as specialized training) was too low, while 42.47% (3 897 people) and 30.44% (2 793 people) believed that the clinical practice opportunities of students were limited, both of which were higher than those in high-income and low-income regions ( P<0.001); 34.91% (5 128 people) of surveyed doctors in low-income regions believed that the investment was insufficient for training bases of residential training, 27.81% (4 085 people) of those held that training bases for specialized training were unevenly distributed, and 33.19% (4 876 people) of those held that continuing medical education was plagued by " insufficient promotion coverage, and insufficient opportunities for primary doctors", all of which being higher than those in high- and middle-income regions ( P<0.001). Conclusions:There is an obvious need to improve the core competence of doctors in the teaching ability dimension of tertiary public hospitals in China, especially in middle- and high-income regions for lifelong learning, and in low-income regions for knowledge and skills; There are differences between postgraduate medical education and continuing medical education systems in regions of different income levels in China. It is necessary to improve the competency oriented postgraduate medical education and continuing medical education systems.
