OBJECTIVE To pr ovide theoretic support for Guiyang to scientifically guide the development of drug retail industry and implement national health policies . METHODS The data were collected through statistical yearbook ，data cloud ， coordinate acquisition device of Application Programming Interface of Baidu map and so on. The spatial distribution characteristics and accessibility of medical insurance designated retail pharmacies （shorted for “designated pharmacies ”）in Guiyang were analyzed by spatial analysis based on Geographic Information System. The related factors for the distribution of designated pharmacies in Guiyang were analyzed by statistical method. RESULTS The number of designated pharmacies ，designated pharmacies per thousand people and designated pharmacies per 10 km2 in Guiyang increased from 2 018，0.41 and 2.51 in 2020 to 2 500，0.42 and 3.11 in 2021，with growth rates of 23.89％，2.44％ and 23.90％ respectively. The service area of the designated pharmacies that residents of Guiyang reached within 15 minutes on foot was 10.27％ of the total service area of designated pharmacies in Guiyang. The results of correlation analysis showed that the correlation coefficients between the regional gross regional production ，total retail sales of consumer goods ，population，urban per capita disposable income and the number of designated pharmacies in Guiyang were 0.999，0.999，0.977 and 0.992，respectively （all P＜0.05）. CONCLUSIONS The distribution of designated pharmacies is insufficient in Guiyang ，the development of designated pharmacies in various administrative regions is uneven ，and the layout of pharmacies is significantly affected by economic and demographic factors. It is suggested that the local government should explore the strategy of scientifically and reasonably expanding the coverage of designated pharmacies in urban and rural areas，promote the rational layout of pharmacies with appropriate economic and demographic policies ，and pay attention to improving the service capacity of designated pharmacies ，so as to improve the quality of life of the people and guide the healthy and high-quality development of drug retail industry.

OBJECTIV E To study composition an d content changes of volatile components during the bleaching process of Atractylodis macrocephala with the water of washing rice. METHODS The raw products of A. macrocephala and bleached products of 5 different bleaching stages were prepared （in the first and second stages ，raw products were bleached with 9-fold volumn of the water of washing rice for 12 h and 24 h，respectively；in the third ，fourth and fifth stages ，the raw products were firstly bleached with 9-fold volumn of the water of washing rice for 24 h，and then bleached with 9-fold volumn of clean water for 12，24 and 48 h，respectively）；the bleaching temperature was set at 26 ℃. The volatile components of raw products of A. macrocephala and its bleached products of 5 different bleaching stages were qualitatively analyzed by using headspace gas chromatography-mass spectrometry. The relative percentage of each component was calculated by peak area normalization method. RESULTS A total of 49 volatile components were identified from raw products of A. macrocephala and its bleached products of 5 different bleaching stages，including 20 common volatile components such as terpinolene ，cyperene and atractylon ，etc. Among them ，33，31，28， 30，28 and 29 volatile components were identified from the raw products of A. macrocephala and the bleached products of the first to fifth stages ，the relative percentages of which were 66.218％ ，64.711％ ，79.410％ ，65.419％ ，67.101％ ，66.818％ ， respectively；among them ，the relative percentage of atractylon in bleached products was the highest in the fourth stage （41.206％），but was the lowest in the third stage （35.926％）. Compared with the raw product ，16 volatile components such as pethylbrene and β-vetivenen were added in the bleaching process ，while 8 volatile components such as ethyl palmitate and β-maaliene were not detected. However ，5 volatile components including 11-rotundene and （－）-valeranone in the bleaching process showed a trend of disappearance-emergence and disappearance-emergence-disappearance. CONCLUSIONS In the third stage，the total relative percentage of each volatile component and the relative percentage of representative dry component as ， atractylone are the lowest in bleached products of A. ； macrocephala，i.e. the bleaching technology of relieving the dry property of A. macrocephala e with the water of washing rice is bleaching with 9-fold volumn of the water of washing rice for 24 h，and then bleaching with 9-fold volumn of clean water for 12 h.

OBJECTIVE To investigate the effect of arctiin （ARC）relieving lipopolysaccharide （LPS）induced inflammatory injury of human nasopharyngeal epithelial cells NP- 69. METHODS The effects of 24 h treatment of 0.000 1，0.001，0.01，0.1， 1.0，10 μmol/L ARC on the proliferation of NP-69 were determined by MTS method. After 0.01，0.1，and 1.0 μmol/L ARC was applied to NP- 69 for 24 h and NP- 69 was pre-treated with 0.01，0.1 and 1.0 μmol/L ARC for 24 h，and then stimulated with 1.0 μg/mL LPS for 24 h，scratch tests were used to detect cell migration in both experiments. LPS stimulated NP- 69 to establish an inflammation injury model. The levels of nitric oxide （NO），tumor necrosis factor α（TNF-α）interleukin-6（IL-6），and IL- 1β in cell supernatants were detected ，and mRNA and protein expression of zonula oecludens protein 1（ZO-1），β-defensin 3（BD3）， Janus kinase 1 （JAK1），signal transducer and activator of transcription 3 （STAT3） in cell supernatant were also detected. RESULTS Compared with normal group ，0.000 1，0.001，0.01，0.1，1.0，10 μmol/L ARC had no effect on the proliferation of NP-69 after 24 h treatment （P＞0.05）. ARC （0.1，1.0 μmol/L）could significantly promote the rate of cell migration （P＜0.05）. For the inflammatory injure of NP- 69 cells stimulated by LPS ，ARC（1.0 μmol/L）could significantly reduce the release of NO ， TNF-α and IL-6（P＜0.05），significantly increased mRNA and protein expression of ZO- 1 and BD 3 but decreased mRNA and protein expression of STAT 3（P＜0.01 or P＜0.05）. CONCLUSIONS ARC has the effect of reducing the inflammatory injury of NP-69 cells induced by LPS ，promoting the physical and immune defense ability of the nasal mucosa epithelial barrierunder inflammatory environment. The mechanism of action may be related to inhibiting IL- 6/JAK1/STAT3 signaling pathway.

BACKGROUND/AIMS: Previous studies reported that integrated information in the brain ultimately determines the subjective experience of patients with chronic pain, but how the information is integrated in the brain connectome of functional dyspepsia (FD) patients remains largely unclear. The study aimed to quantify the topological changes of the brain network in FD patients. METHODS: Small-world properties, network efficiency and nodal centrality were utilized to measure the changes in topological architecture in 25 FD patients and 25 healthy controls based on functional magnetic resonance imaging. Pearson's correlation assessed the relationship of each topological property with clinical symptoms. RESULTS: FD patients showed an increase of clustering coefficients and local efficiency relative to controls from the perspective of a whole network as well as elevated nodal centrality in the right orbital part of the inferior frontal gyrus, left anterior cingulate gyrus and left hippocampus, and decreased nodal centrality in the right posterior cingulate gyrus, left cuneus, right putamen, left middle occipital gyrus and right inferior occipital gyrus. Moreover, the centrality in the anterior cingulate gyrus was significantly associated with symptom severity and duration in FD patients. Nevertheless, the inclusion of anxiety and depression scores as covariates erased the group differences in nodal centralities in the orbital part of the inferior frontal gyrus and hippocampus. CONCLUSIONS: The results suggest topological disruption of the functional brain networks in FD patients, presumably in response to disturbances of sensory information integrated with emotion, memory, pain modulation, and selective attention in patients.

OBJECTIVETo investigate the pro-angiogenic effects of several multiple myeloma (MM) cell line culture supernatants on human bone marrow endothelial cell (HBMEC) proliferation, migration, and capillary formation, and the anti-angiogenic effects of thalidomide.

METHODSHBMEC was cultured in the presence of MM cell lines (IM9, XG1, U266 and MOLP-5) supernatants. Proliferation and migration of HBMEC were determined, capillary-like tubule formation of HBMEC was examined in fibrin and Matrigel. The inhibiting effect of thalidomide was investigated by adding it into myeloma cell line culture supernatants. Vascular endothelial growth factor (VEGF) was measured by ELISA.

RESULTS(1) MM cell lines culture supernatants promoted HBMEC proliferation and migration. (2) In fibrin and Matrigel, capillary-like tubule network formation promoted by the supernatants. (3) All of these effects could be inhibited by thalidomide. (4) This effect was not related to VEGF in the supernatants.

CONCLUSIONSMM cell line promote proliferation, migration and tubule formation by secreting VEGF or other several cytokines. Thalidomide can inhibit these effects.

OBJECTIVETo evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy.

METHODSWe retrospectively collected data on 24 patients who underwent surgical management in the past ten years in two hospitals in China and Madras Medical Mission in India. Myomectomy was carried out on all patients. Among them 3 patients underwent mitral valve replacement; 2 patients underwent mitral valve repair (anterior mitral leaflet plication); 2 patients underwent aortic valve replacement; 1 patient underwent aortic valve repair; 2 patients underwent aortic root replacement; 1 patient underwent Bentall's procedure and 1 patient underwent coronary artery bypass grafting because of a breached muscle bridge.

RESULTSOne patient died of post-operative heart failure. The mean follow-up time was 4.3 years. There was significant improvement in the symptomatic status. Sixteen patients were asymptomatic with good effort tolerance and only four patients had New York heart association (NYHA) Classes I-II due to associated valvular lesions.

CONCLUSIONOur experience proved that symptomatic hypertrophic obstructive cardiomyopathy or non-symptomatic hypertrophic obstructive cardiomyopathy with combined heart disease is indication for surgery as surgical intervention could get better clinical results in this kind of patients compared with other non-surgical method because it beneficially reduces the systolic anterior motion (SAM) of the mitral valve leaflet, which could not be avoided by other non-surgical treatment.

Cytoplasmic male sterility is an important way to utilize wheat heterosis. The purpose of thisstudy was to identify cytoplasmic type of three wheat male sterile lines. Amplified fragment length polymorphism (AFLP) marker technique was used to analyze the wheat mitochondrial DNA. We isolated mitochondria by differential centrifugation and density gradient ultracentrifugation. The results show that the extracted mitochondrial DNA was pure. It was suitable for PCR and genetic analysis. We got 4 pairs of specific primers from 64 primers combinations. Primer E1/M7 amplified 3 specific fragments in ms(Kots)-90-110. Primer E4/M2 generated 2 specific fragments in ms(Ven)-90-110. Primer E7/M6 amplified 2 specific fragments in ms(S)-90-110. Primer E6/M4 produced 2 specific fragments in ms(Kots)-90-110. Four specific primers could be used to identify three cytoplasmic types of Aegilops kotschyi, Ae. ventricosa and Triticum spelta. It provided the molecular basis to further study the mechanism of wheat cytoplasmic male sterility.

OBJECTIVETo determine the effectiveness of an instant haw beverage in regulating lipid disturbance, enhancing antioxidant enzyme activity and immune function.

METHODSData was collected from 60 hyperlipidemic subjects. In this crossover design, each subject randomly received either the instant haw beverage (100 ml corresponding to 3 g of haw powder or 30 g of fresh haw fruit plus the carrier-guar gum plus some starch) or placebo (guar gum 1.5 g plus some starch as the carrier of the beverage) twice daily. Each supplementation lasted 31 days with a 28-day washout period between treatments.

RESULTSThe instant haw beverage significantly reduced total serum cholesterol (9.6%), triglyceride (12.1%), LDLC (18%) while significantly increased SOD activities (7.5%). The placebo was shown to have positive results in some of the lipid profiles, though the effects of the instant haw beverage demonstrated greater significance. Serum triglyceride levels were significantly decreased and SOD activity significantly increased only as subjects were supplemented with the instant haw beverage while no significant changes were seen with placebo.

CONCLUSIONSupplementation with the instant haw beverage positively affects blood lipid profile, antioxidant status and immune function in individuals with hyperlipidemia.
