In this work, to comprehensively analyze the flow field characteristics of a normal slot plasma synthetic jet actuator, three-dimensional simulation models are established for both normal slot and normal orifice actuators. A detailed comparative analysis of the three-dimensional flow field characteristics of these two actuators is performed. The results indicate that the motion shockwaves and jets generated by the normal slot actuator cover a larger and more uniform region, showing planar characteristics and excellent flow control uniformity. The total pressure ratio for the normal slot actuator is 3.59, significantly higher than the value of 3.50 for the normal orifice actuator, indicating lower pressure loss in the former. Additionally, the normal slot has a larger average exit Mach number (Ma), indicating a stronger flow control capability. It also achieves the peak Ma in a shorter time, indicating a faster momentum output response. Therefore, compared with the normal orifice actuator, the normal slot actuator has better potential for flow control.

Physics ,QC1-999 - Abstract
Neutrinoless double beta decay is one of the most sensitive probes for new physics beyond the Standard Model of particle physics. One of the isotopes under investigation is ^{136}Xe, which would double beta decay into ^{136}Ba. Detecting the single ^{136}Ba daughter provides a sort of ultimate tool in the discrimination against backgrounds. Previous work demonstrated the ability to perform single atom imaging of Ba atoms in a single-vacancy site of a solid xenon matrix. In this paper, the effort to identify signal from individual barium atoms is extended to Ba atoms in a hexa-vacancy site in the matrix and is achieved despite increased photobleaching in this site. Abrupt fluorescence turn-off of a single Ba atom is also observed. Significant recovery of fluorescence signal lost through photobleaching is demonstrated upon annealing of Ba deposits in the Xe ice. Following annealing, it is observed that Ba atoms in the hexa-vacancy site exhibit antibleaching while Ba atoms in the tetra-vacancy site exhibit bleaching. This may be evidence for a matrix site transfer upon laser excitation. Our findings offer a path of continued research toward tagging of Ba daughters in all significant sites in solid xenon.

This study aimed to investigate the efficacy and molecular mechanisms of ZSP1603 as a novel anti-fibrotic compound.The unilateral left pulmonary fibrosis model was established in the Sprague Dawley (SD) rats. The bilateral pulmonary fibrosis model was established in the C57BL/6J mice. The therapeutic treatment regimen began after the induction of pulmonary fibrosis. The preventive treatment regimen began on the first day of bleomycin administration. Animals were randomly divided into the sham, model, Nintedanib, and ZSP1603 treatment groups. Haematoxylin and eosin (HE) and Masson's trichrome staining were performed to evaluate pulmonary injury, inflammation, and fibrosis. Cell Counting Kit-8 (CCK-8) assay and Western blot were used to investigate the effects and mechanisms of ZSP1603 on the proliferation of primary human pulmonary fibroblasts (pHPFs). The messenger ribonucleic acid (mRNA) expression of transforming growth factor (TGF)-β1, tissue inhibitor of metalloproteinase 1 (TIMP-1), and collagen 1A1 (COL1A1) in pHPFs was detected by quantitative Real Time-Polymerase Chain Reaction (PCR).ZSP1603 inhibited the proliferation of pHPFs in vitro by blocking the platelet-derived growth factor receptor-β (PDGF-Rβ) and extracellular signal-regulated kinase (ERK) signalling pathway. ZSP1603 also inhibited the differentiation of pHPFs by reducing the expression of TGF-β1, TIMP-1, and COL1A1. ZSP1603 significantly attenuated pulmonary injury, inflammation, and fibrosis in vivo in four independent animal studies of pulmonary fibrosis.ZSP1603 is an effective anti-fibrotic compound with clear mechanisms.

An overview of Sun–Sky Radiometer Observation Network (SONET) measurements in China is presented. Based on observations at 16 distributed SONET sites in China, atmospheric aerosol parameters are acquired via standardization processes of operational measurement, maintenance, calibration, inversion, and quality control implemented since 2010. A climatology study is performed focusing on total columnar atmospheric aerosol characteristics, including optical (aerosol optical depth, ÅngstrÖm exponent, fine-mode fraction, single-scattering albedo), physical (volume particle size distribution), chemical composition (black carbon; brown carbon; fine-mode scattering component, coarse-mode component; and aerosol water), and radiative properties (aerosol radiative forcing and efficiency). Data analyses show that aerosol optical depth is low in the west but high in the east of China. Aerosol composition also shows significant spatial and temporal variations, leading to noticeable diversities in optical and physical property patterns. In west and north China, aerosols are generally affected by dust particles, while monsoon climate and human activities impose remarkable influences on aerosols in east and south China. Aerosols in China exhibit strong light-scattering capability and result in significant radiative cooling effects.

This study intended to explore the efficacy of computed tomography (CT)-guided implantation of iodine-125 (125I) seeds in the treatment of refractory malignant tumors with cancer pain and its influence on tumor markers in the serum.76 patients with refractory malignant tumors accompanied by cancer pain that received treatments in LongHua Hospital Shanghai University of Traditional Chinese Medicine from September 2013 to August 2014 were selected. They were divided into control group and observation group using a random number table (38 patients in each group). Patients in the control group received simple chemotherapy, while those in the observation group undergone CT-guided implantation of 125I seeds in combination with chemotherapy. Recent efficacy and 1-3-year survival rate were compared between the two groups of patients. The degree of pain relief after treatment was also compared between the two groups of patients. Electrochemiluminescence method was used to detect the concentrations of carcinoembryonic antigen (CEA), sugar chain antigen 199 (CA 199), sugar chain antigen 125 (CA 125), neuron-specific enolase (NSE) and cytokeratin-19-fragment (CYFRA21-1) in the two groups of patients before treatment, and 3 days, 7 days and 30 days after treatment.Recent disease control rate of the patients in the observation group was higher than that of the patients in the control group (p0.05). The 1-3-year survival rate after surgery in the observation group was significantly higher than that in the control group (p0.05). The total efficiency of pain control in the observation group was significantly higher than that in the control group (p0.05). The levels of tumor markers in the two groups of patients were significantly decreased after treatment, while the reduction in the observation group was more evident than that in the control group (p0.05).Our results showed that CT-guided implantation of 125I seeds is effective for the treatment of patients with refractory malignant tumors accompanied by cancer pain. It can reduce the levels of tumor markers, improve the survival rate and prolong the survival time of the patients.

Flow control methods have been gradually applied to improve the flow field characteristics of axial compressors. However, most of the current research is focused on the cascade, and few studies have taken a compressor as the research object. Therefore, a 3.5-stage transonic axial compressor is adopted to explore the characteristics of different flow control schemes. The effects of the micro-vortex generator (MVG), segmented boundary layer suction (BLS), and combined technology (COM) on the MVG and BLS are compared by the numerical simulation method. The research results are summarized as follows. The excessive accumulated low-energy fluid in the blade passage induces the occurrence of a corner stall in the last stage stator of an axial compressor. At this time, the compressor can still work, but the performance has accelerated deterioration. The flow characteristics are effectively improved when the MVG is introduced, the stall margin improvement ΔSM and the peak efficiency improvement Δηe of the last stage are 2.1% and 1.02%, respectively. Moreover, the BLS shows advantages in removing the three-dimensional reverse flow and decreasing the total pressure loss compared with the MVG, the ΔSM of the last stage is 2.69%, and the Δηe is 1.83%. When the combined technology is applied, it shows a significant advantage in delaying the occurrence of a corner stall, and the stall margin of the last stage is improved by 2.71%. Based on a quantitative analysis method using loss sources, the three flow control schemes show significant advantages in reducing the secondary flow loss sources and the wake loss sources. Above all, the BLS shows significant advantages in reducing the total pressure loss, and the COM shows an advantage in expanding the stable operating range. The research results will provide a reference for studies of flow control methods related to reducing flow losses and widening stability margins.

Abstract Liquid xenon time projection chambers are promising detectors to search for neutrinoless double beta decay (0 $$\nu \beta \beta $$ ν β β ), due to their response uniformity, monolithic sensitive volume, scalability to large target masses, and suitability for extremely low background operations. The nEXO collaboration has designed a tonne-scale time projection chamber that aims to search for 0 $$\nu \beta \beta $$ ν β β of $$^{136}$$ 136 Xe with projected half-life sensitivity of $$1.35\times 10^{28}$$ 1.35 × 10 28 yr. To reach this sensitivity, the design goal for nEXO is $$\le $$ ≤ 1% energy resolution at the decay Q-value ( $$2458.07\pm 0.31$$ 2458.07 ± 0.31 keV). Reaching this resolution requires the efficient collection of both the ionization and scintillation produced in the detector. The nEXO design employs Silicon Photo-Multipliers (SiPMs) to detect the vacuum ultra-violet, 175 nm scintillation light of liquid xenon. This paper reports on the characterization of the newest vacuum ultra-violet sensitive Fondazione Bruno Kessler VUVHD3 SiPMs specifically designed for nEXO, as well as new measurements on new test samples of previously characterised Hamamatsu VUV4 Multi Pixel Photon Counters (MPPCs). Various SiPM and MPPC parameters, such as dark noise, gain, direct crosstalk, correlated avalanches and photon detection efficiency were measured as a function of the applied over voltage and wavelength at liquid xenon temperature (163 K). The results from this study are used to provide updated estimates of the achievable energy resolution at the decay Q-value for the nEXO design.

To evaluate and compare the anterior corneal asphericity after small incision lenticule extraction(SMILE)and femtosecond laser in situ keratomileusis(FS-LASIK).In this case-control study, 45 subjects who underwent SMILE operation comprised the study group, and 33 subjects with FS-LASIK operation comprised the control group. The asphericity coefficient Q-value of the right eyes in both groups was measured at diameters of 6, 7, 8 and 9 mm, respectively, before surgery and at 1 day, 1 week, 1 month and 6 months following surgery. The correlation between the variation of Q-value and the central cutting depth was analyzed.The Q-value of anterior corneal surface was 0.85 ± 0.31, 0.80±0.28, 0.69±0.25 and 0.51±0.23 after SMILE, and 1.13±0.56, 1.01±0.47, 0.80±0.39 and 0.51±0.31 after FS-LASIK at 1 week. In both groups, the Q-value was significantly different before and after surgery(P0.05); there were interaction effects between the operation method and time; the difference between the two groups at 6-mm and 7-mm diameters was statistically significant(P0.05). The variation of the Q-value before and after operation(ΔQ)showed significant difference(P6mm=0.004, P7mm=0.014)between the two groups at 6-mm and 7-mm diameters. The cap diameter of the SMILE group was smaller than that of the FS-LASIK group, but the cutting depth was larger. There was no correlation between ΔQ and the cap/disc diameter. It showed a linear relationship(P0.05)between ΔQ and the central cutting depth at all examined diameters in the two groups, and the relation degree in the FS-LASIK group was superior to the SMILE group.Both SMILE and FS-LASIK operations can change the negative Q-value of the anterior corneal surface to the positive. The impact of SMILE on the asphericity is smaller than that of FS-LASIK. (Chin J Ophthalmol, 2016, 52: 681-685).

To investigate changes in posterior corneal elevation after small incision lenticule extraction (SMILE) and related factors.Retrospective case series study. Eighty-three eyes of 44 myopic patients undergoing SMILE were examined with the Pentacam preoperatively, and at 1 day, 1 month, 3 months, and 6 months postoperatively. Posterior corneal elevation at the corneal apex and 0°, 45°, 90°, 135°, 180°, 225°, 270° and 325° points of the 2 mm and 6 mm diameter (total, 17 points) was analyzed.The changes in posterior corneal elevation at 1 day, 1 month, 3 months, and 6 months were(-1.72±2.59), (-0.98±2.37), (-0.45±1.81) and (-0.25±2.20) μm, respectively, at the corneal apex. The results were statistically significant (t=6.07, 3.75, 6.07; P0.05), except 6 months. The changes in posterior corneal elevation were (-1.42±2.06),(-0.69±1.86), (-0.30±1.50) and(-0.22±1.58) μm, respectively, in the 2 mm circle. The results of 1 day and 1 month were statistically significant (t=6.28, 6.28, P0.05). The changes in posterior corneal elevation were (1.48±1.47),(0.98±1.32),(0.90±1.31) and (0.90±1.16) μm, respectively, in the 6 mm circle .The results were totally statistically significant (t=6.28, 6.28, P0.05). There were statistically significant differences between 1 month and 1 day postoperatively in the corneal apex, 2 mm and 6 mm circles. The changes were (0.75±2.55),(0.73±1.97) and(-0.50±1.60) μm. There were statistically significant differences between 3 months and 1 month postoperatively in the corneal apex and 2 mm circle. The changes were (0.53±2.22) and (0.39±1.80) μm. No significant change was found in the 6 mm circle. Between postoperative 6 months and 3 months, there were no statistically significant differences. The spherical equivalent, intraocular pressure, ablation depth, residual bed thickness, corneal hysteresis, and corneal resistance factor had no obvious correlation with the changes in posterior corneal elevation.After SMILE, the surrounding cornea was slightly forward, while the central posterior cornea was slightly backwards, and returned gradually. The spherical equivalent, intraocular pressure, ablation depth, residual bed thickness, corneal hysteresis, and corneal resistance factor had no obvious correlation with the changes in posterior corneal elevation.

We examined a possible association between HLA-A and -B polymorphisms and susceptibility to Henoch-Schonlein purpura (HSP) in Han and Mongolian children in Inner Mongolia, through a case-control study. Two hundred and sixty-eight unrelated children were enrolled, including 56 Mongolian and 50 Han children with HSP, 66 healthy Mongolian and 96 healthy Han children as a control group. HLA-A and -B alleles were indentified by PCR-sequence-specific oligonucleotide analysis and were further analyzed by PCR-sequencing-based typing (SBT). Frequencies of HLA-A*11, HLA-B*15 in Mongolian patients and HLA-A*26, HLA-B*35, HLA-B*52 in Han patients were higher than those in the corresponding control group (P < 0.05), while frequencies of HLA-B*07 and -B*40 in Mongolian HSP patients were lower than those in the control group (P < 0.05). Further analysis using PCR-SBT showed that all HLA-A*11 were HLA-A*1101, and most HLA-B*15 were HLA-B*1501 in Mongolian HSP patients. All HLA-A*26 were HLA-A*2601 and HLA-B*35 were mostly HLA-B*3503 in Han patients. There were more Han patients with severe manifestations than Mongolian patients (P < 0.05). Frequencies of HLA-A*26, HLA-B*35 and HLA-B*52 in Han patients were higher than in Mongolian patients (P < 0.05). We conclude that HLA-A*11(*1101) and -B*15(*1501) are associated with susceptibility to HSP in Mongolian children and HLA-A*26(*2601), HLA-B*35(*3503) and HLA-B*52 are associated with susceptibility to HSP in Han children. HLA-B*07 and -B*40 may be protective genes in Mongolian children. The different frequencies of HLA-A and -B in Mongolian and Han children may be responsible for the different manifestations in these two ethnic groups.

Low-T eclogites in the North Qilian orogen, NW China share a common assemblage of garnet, omphacite, glaucophane, epidote, phengite, quartz and rutile with or without paragonite. Phase relations for the low-T eclogites can be modelled well in the system NCKFMASHO with the updated solid-solution models for amphibole and clinopyroxene. Garnet in the eclogite typically exhibits growth zonations in which pyrope increases while grossular somewhat decreases from core to rim, which is modelled as having formed mainly in the P–T conditions of lawsonite-eclogite facies at the pre-peak stage. Omphacite shows an increase in jadeite component as aegirine and also total FeO decrease in going from the inclusions in garnet to grains in the matrix, and from core to rim of zoned crystals, reflecting an increase in metamorphic P–T conditions. Glaucophane exhibits a compositional variation in X(gl) (= Fe2+/(Fe2+ + Mg)) and F(gl) (= Fe3+/(Fe3+ + Al) in M2 site), which decrease from the inclusions in garnet to crystals in the matrix, consistent with an increase in P–T conditions. However, for zoned matrix crystals, the X(gl) and F(gl) increase from core to rim, is interpreted to reflect a late-stage decompression. Using composition isopleths for garnet rim and phengite in P–T pseudosections, peak P–T conditions for three samples Q5–45, Q5–01 and Q7–28 were estimated as 530–540 °C at 2.10–2.25 GPa, 580–590 °C at 2.30–2.45 GPa and 575–590 °C at 2.50–2.65 GPa, respectively, for the same assemblage garnet + omphacite + glaucophane + lawsonite (+ phengite + quartz + rutile) at the peak stage. The eclogites suggest similar P–T ranges to their surrounding felsic–pelitic schists. During post-peak decompression of the eclogites, the most distinctive change involves the transformation of lawsonite to epidote, releasing large amount of water in the rock. The released fluid promoted further growth of glaucophane at the expense of omphacite and, in appropriate bulk-rock compositions, paragonite formed. The decompression of eclogite did not lead to pronounced changes in garnet and phengite compositions. Peak P–T conditions of the North Qilian eclogite are well constrained using both the average P–T and pseudosection approaches in Thermocalc. Generally, the conventional garnet–clinopyroxene geothermometer is too sensitive to be used for constraining the temperature of low-T eclogite because of the uncertainty in Fe3+ determination in omphacite and slight variations in mineral compositions because of incomplete equilibration.

Papillary thyroid carcinoma (PTC) is the most common type of thyroid carcinoma, and our understanding of its pathogenesis is incomplete. To elucidate the mechanisms underlying such progression and identify novel diagnostic markers, we aimed to discover the underlying gene associated with PTC. Integrated analysis of microarray datasets was performed to identify differentially expressed genes (DEGs) between PTCs and normal tissues. GO enrichment analysis and KEGG pathway enrichment analysis were then performed to uncover the functions of DEGs. Furthermore, the protein-protein interaction (PPI) network of DEGs was constructed. Five GEO datasets were obtained. Totally, 154 DEGs across the studies were identified, including 26 upregulated and 128 downregulated DEGs. In the PPI network, MLLT1, DLG2, and EFEMP1 were the hub proteins, in which DLG2 and EFEMP1 were involved in tumor progression. Among the top 10 up- and downregulated genes, the dysregulation genes of TPO, CDH16, and MPPED2 may be closely related to the tumorigenesis of PTC. By integrated analysis of multiple gene expression profiles, we propose that the dysregulation genes of TPO and MPPED2 will be the promising diagnostic markers for PTCs.

Abstract Gravitational‐wave high‐energy Electromagnetic Counterpart All‐sky Monitor (GECAM) is a space‐borne instrument dedicated to monitoring high‐energy transients, including Terrestrial Gamma‐ray Flashes (TGFs) and Terrestrial Electron Beams (TEBs). We implemented a TGF/TEB search algorithm for GECAM, with which 147 bright TGFs, 2 typical TEBs and 2 special TEB‐like events are identified during an effective observation time of ∼9 months. We show that, with gamma‐ray and charged particle detectors, GECAM can effectively identify and distinguish TGFs and TEBs, and measure their temporal and spectral properties in detail. A very high TGF‐lightning association rate of ∼80% is obtained between GECAM and GLD360 in east Asia region.

Calcium-alginate beads coated with quaternized chitosan were prepared in a neutral environment, and morphologies were observed by SEM. Optimum conditions for the encapsulation and retention of a model drug (brilliant blue, BB) in acid were obtained from studies of preparation conditions, including alginate and quaternized chitosan concentration, calcium chloride (CaCl2) concentration in the gelling medium and by comparing one-step and two-step preparation methods. Results showed that very high BB encapsulation efficiency (99%, w/w) and low leakage in acid (8%, w/w) was achieved from dry beads when 2.0% (w/v) alginate was dropped into 1.0% (w/v) CaCl2 containing 0.3% (w/v) quaternized chitosan by a one-step method. The release of BB in 0.9% (w/v) NaCl was modulated by coating calcium-alginate with different weight average molecule weight (Mw) and degree of substitution (DS) of quaternized chitosan. A decreased of Mw accelerated the release of BB and a high DS value significantly decreased the release in 0.9% (w/v) NaCl.

Surface plasmon resonance (SPR) and quartz crystal microbalance (QCM) techniques have been studied in label- free immunosensors for direct detection of bacteria. However, there is a lack of comparative investigations on SPR and QCM immunosensors. In this study, SPR and QCM immunosensors were compared for their applications in bacterial detection using Escherichia coli O157:H7 as a model pathogen. In both immunosensors, affinity-purified polyclonal antibodies were used as capture antibodies and Protein A method was used for antibody immobilization. The stepwise assembly of the immunosensors was characterized by SPR, QCM, and cyclic voltammetry. Both SPR and QCM could detect E. coli O157:H7 in 1 h with detection ranges of 105 to 108 and 106 to 108 CFU/mL, respectively. QCM was more sensitive than SPR in terms of both detection limit and signal-to-noise ratio. For both immunosensors, no significant interference was found from brain heart infusion (BHI) broth or Salmonella Typhimurium. The binding efficiency of the QCM immunosensor at 105 to 108 CFU/mL was found to be 95.9% to 2.9%, decreasing with increasing cell concentration.

The purpose of this study was to evaluate the ethnic difference in bone mass between Japanese and Inner Mongolian young premenopausal women and to assess the contribution of lifestyle related and anthropometric factors to bone mass. We studied 33 Japanese and 44 Inner Mongolian healthy young women, aged 20-34 years, in urban area. Speed of sound (SOS), broadband ultrasound attenuation (BUA) and stiffness index (SI) were measured at the calcaneus using quantitative ultrasound (QUS) analysis. Age at menarche, regularity of menstruation and lifestyle related factors were estimated by a self-reported questionnaire. There were no differences between the two groups in age, height, weight, BMI, regularity of menstruation, frequency of meat intake, frequency of yellow-green vegetable intake and exercise habit. Japanese women had significantly lower age at menarche and higher proportion of milk consumption habit at junior high school, senior school and present. Before adjustment, Japanese women had significantly higher SOS and SI than Inner Mongolian women. However, after adjustment for age at menarche and milk consumption habit at junior high school, both of which were significantly different between groups, no group-differences remained in either SOS or SI. These results suggest that the differences in age at menarche and milk consumption habit at junior high school, which relate to hormonal and nutritional status during puberty, may account for the differences in bone mass between Japanese and Inner Mongolian young women.

Taurine has beneficial effects on lipid metabolism in experimental animals fed with high-cholesterol or high fat diets. Whether taurine benefits lipid metabolism in humans has rarely been investigated. The aim of this study was to evaluate the effects of taurine on serum lipids in overweight or obese young adults. Thirty college students (age: 20.3+/-1.7 years) with a body mass index (BMI)/=25.0 kg/m(2), and with no evidence of diabetes mellitus were selected and assigned to either the taurine group (n=15) or the placebo group (n=15) by double-blind randomization. Taurine 3 g/day or placebo was taken orally for 7 weeks. Triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and plasma glucose were measured before and after supplementation. The atherogenic index (AI) was calculated as (TC-HDL-C)/HDL-C. There were no differences in any baseline parameter between the two groups. Taurine supplementation decreased TG and AI significantly. Body weight also reduced significantly in the taurine group. These results suggest that taurine produces a beneficial effect on lipid metabolism and may have an important role in cardiovascular disease prevention in overweight or obese subjects.

Human lung squamous carcinoma cell line(TUL cell) was treated with 5 x 10(-6) mol.L-1 all-trans retinoic acid(ATRA). Cell numbers were estimated by 0.4% trypon blue stain. MTT test was used for determining the percentage of cell growth inhibition(GI). DNA syntheses of cells were evaluated by 3H-thymidine incorporation. Cell ultrastructure was examined by transmission electron microscope(TEM). TUL cells were treated with or without ATRA, and transplanted in cutaneous of Balb/c nude mice. The results showed that: 1. The speed of cell growth in study group was smaller than that in control group. 2. The GI of cell lines TUL was 42.3%. 3. The percentage of 3H-thymidine incorporation of TUL cells was declined significantly. 4. Ultrastructure under TME showed that TUL cells treated with ATRA was suppressed. These results suggest that ATRA has the effects on growth-inhibition and differentiation-induction of TUL cell.

An API-LC/MS/MS method was developed for the identification of the medicinal herb Podophyllum emodi based on the profile of its aryltetrahydronapthalene and related lignan marker compounds. This was done by matching the structural information from the tandem mass spectrometric data with those lignan marker compounds already reported for the herb. The method could be employed in the absence of reference standards for the markers and was particularly useful in view of the scarcity of supply of these chemical standards. It has been used successfully to differentiate Podophyllum emodi from two commonly used medicinal herbs of a different genus but having similar appearance, Radix clematidis and Radix gentiana, as well as a closely related herb, Podophyllum peltatum.

A careful fundus examination was carried out in 65 patients with diabetes mellitus, who were divided into two groups according to the changes of fundus showing or not showing diabetic retinopathy. The hemorrheological manifestation, the serum lipids and the course of disease in the two groups were observed and compared respectively. The result showed that abnormal hemorrheological rate in the group with diabetic retinopathy was much higher than that in the group without diabetic retinopathy, with the content of serum triglyceride in the former group being obviously higher than that in the latter group, and no statistical significance were shown in the course of disease between the two groups. In the light of the principle of hemorheology, further study was done on the mechanism of the angiopathy and microangiopathy which was caused by diabetes. It could help us to analyze the relationship between the diabetic retinopathy and the hemorrheological change. We suggest that it is important that dynamic observation be carried out of hemorrheological manifestation for the clinical prevention and treatment of microcirculatory disease.

Three geranium oils were separated, identified and compared by high resolution cross-linked fused silica capillary GC and GC-MSD. It was found that their chemical constituents are very similar, but the contents of some components (linalool, citronellol, cis-caryophyllene and guaiene) differ appreciably. Pharmacological experiments showed that citronellol, citronellyl formate, geraniol and citronellyl acetate exhibited marginal antitumour activities. The activity of the latter two components has not been reported in the literature.
