Objective: To compare the efficacy difference between moxibustion at sensitized-acupoints and non-sensitized- acupoints using the same group of acupoints. Methods: A total of 139 patients with chronic superficial gastritis were divided into a sensitized acupoint group (102 cases) and a non-sensitized acupoint group (37 cases) based on whether acupoint sensitization occurred. The SPSS version 19.0 statistical software propensity score matching function was used to balance the baseline data between the groups. Finally, 29 pairs of matched patients were included, namely 29 cases in the sensitized acupoint group and 29 cases in the non-sensitized acupoint group. Both groups were treated with moxibustion therapy. The treatment lasted for 30 min per time, and was performed every other day for 8 weeks. Changes in the traditional Chinese medicine (TCM) symptom score and the short-form 36-item health survey (SF-36) score in both groups were observed before and after treatment, as well as the clinical efficacy. Results: The covariates of age, course of disease, TCM symptom score and SF-36 score in the two groups were balanced after matching (all P>0.05). After treatment, the total effective rate was 100.0％ in the sensitized acupoint group and 79.3％ in the non-sensitized acupoint group. The difference in the total effective rate between the two groups was statistically significant (P<0.01). After treatment and at the 4-week follow-up, the TCM symptom scores in the sensitized acupoint group were significantly lower than those in the non-sensitized acupoint group (all P<0.01); the SF-36 scores in the sensitized acupoint group were significantly higher than those in the non-sensitized acupoint group (all P<0.01). Conclusion: With the same group of acupoints, the sensitized acupoints have a better therapeutic effect and long-term efficacy than the non-sensitized acupoints in the treatment of chronic superficial gastritis.

Background Intravitreal injection of triamcinolone acetonide (TA) can effectively eliminate central vein occlusion macular edema and improve visual acuity, and photopic negative response (PhNR) can reflect the inner retinal function of RGCs and their axons. It is possible there is a correlation between these two observations.Objective This study was to evaluate the changes of PhNR of flash electroretinogram (F-ERG) after intravitreal injection of TA for macular edema in central retinal vein occlusion ( CRVO ). Methods Thirteen eyes of 12 patients with macular edema caused by CRVO received an injection of 0. 1 ml (4 rg) of TA. PhNR,visual acuity and retinal thickness of macular area were assessed with Roland RETI scan 3. 15 system,decimal visual chart and Stratus optical coherence tomography (OCT) before and 4 weeks after the administration of TA. Written informed consent was obtained from each subject before any medical procedure. Results Visual acuity was improved in 12 eyes and stable in 1 eye 4 weeks following the intravitreal injection of TA. OCT showed that the retinal thickness of the macular area was reduced ;meanwhile,elevation of the amplitude of PhNR also was seen in the F-ERG after the administration of TA in comparison with before the administration of TA. The calculated results determined that the visual acuities were 0. 32t0. 12 and 0. 48±0. 09 (t=6. 325 ,P=0. 000) ,and the retinal thickness values of the macular area were (459.46± 131.31 ) μm and ( 297.54 ±43.31 ) μm ( t = 5.961, P = 0. 000 ), and the average amplitude of PhNR were ( 80. 23±22.96 ) μV and (61.28 ±20. 16 ) μV ( t = 4. 438, P = 0. 001 ) before and after the intravitreal injection of TA, respectively,showing significant differences. No significant correlation was found between PhNR amplitude and retinal thickness of the macular area both before and after the administration of TA ( before: r = 0. 587, P = 0. 035; after:r=-0. 011 ,P = 0. 971 ). Conclusion PhNR can be used for evaluating the status of inner retina after intravitreal injection of TA for macular edema of CRVO.

OBJECTIVETo observe the differential effect of joint ultrasound on the syndrome differentiation of rheumatoid arthritis (RA) by observing the high frequency ultrasound performances among inactive stage and different syndromes in active stage.

METHODSTotally 83 RA patients in the active stage were assigned to the dampness heat syndrome group (DHS, 59 cases)and the cold dampness syndrome group (CDS, 24 cases) according to Chinese medicine (CM) syndrome typing. Besides, 20 RA patients in the remission stage were recruited as the control group (abbreviated as the remission group). By using high frequency ultrasound and power Doppler ultrasound technology, a comparative observation of synovitis, tenosynovitis, synovial blood flow, and bone erosion in the 2nd-5th metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints, wrist joints, knee joints, the second and the fifth metatarsophalangeal (MTP) joints (a total of 24 joints) was performed in all patients. Correlation analyses were performed between the ultrasound performance, laboratory indices, and the disease activity. Ultrasound data of each RA patient were analyzed by their total scores. Χ2 test was used for enumeration data. The measurement data was expressed as x ± s. One-way ANOVA was used for data of normal distribution, while non- parametric test was used for data of non-normal distribution. Correlation analysis of two variables was performed for clinical indicators and ultrasound indicators. Its significance was detected using Pearson correlation.

RESULTSCompared with the remission group, the severity degree of synovitis, tenosynovitis, synovial blood flow, and bone erosion significantly increased in the DHS group (P < 0.01). There was statistical difference in ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF (P < 0.05, P < 0.01). There was statistical difference in the severity degree of synovitis and synovial blood flow, and DAS28 score in the CDS group (P < 0.05). Compared with the CDS group, there was statistical difference in the four ultrasound indices (P < 0.05, P < 0.01), ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF in the DHS group (P < 0.05, P < 0.01). There was no statistical difference in G, IgG, IgA, or IgM among the three groups (P > 0.05). There existed positive correlation between ESR and the synovitis degree, synovial blood flow, and bone erosion in the DHS group (r = 0.444, 0.397, 0.486, P < 0.05).There existed positive correlation between ESR and the synovitis degree, bone erosion, and synovial blood flow in the DHS group (r = 0.378, 0.270, P < 0.05). There existed positive correlation between the DAS28 score and the synovitis degree and synovial blood flow in the DHS group (r = 0.304, 0.351, P < 0.05).

CONCLUSIONSThe inflammation degree was the most severe in RA patients of DHS. High frequency ultrasound could provide better evidence for Chinese medical syndrome differentiation of RA patients.

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

Background Sweep pattern visual evoked potential (SVEP) is an objective method of visual test.There is a clear correlation between SVEP acuity and subjective vision,but they are not identical.Recent studies showed that new regression method can improve the accuracy of SVEP acuity. Objective This trial was to investigate and compare the outcome between amplitude-spatial frequency (A-SP) regression method and amplitudelogVA (A-logVA) regression method in extrapolating the SVEP acuity.Methods SVEP was recorded in 113 eyes of 64 subjects using GT-2000 ( Guo Te,China) with the gratings of 10 different spatial frequency from 0.99 to 12.89 cpd as stimulus.The 1 13 eyes included cataract,glaucoma,corneal disease,optical neuropathy,retinal disease,ocular trauma,refractive error and normal eyes.The correlation were analyzed of SVEP acuity,decimal visual acuity and LogMAR visual acuity.The response were averaged and DFT on the monitor display.SVEP acuity was calculated by extrapolating 0 response amplitude.Results The correlation indices of decimal visual acuity curves obtained by the A-logVA function was 0.663,and that obtained by the A-SP function was 0.705.The positive correlation was seen between subjective decimal visual acuity and A-logVA decimal visual acuity (r =0.540,P＜ 0.01 ) and between subjective decimal acuity and decimal acuity calculated by the A-SP regression method (r=0.620,P＜0.01 ).SVEP decimal acuity calculated by the A-SP function regression method was significantly different from the that calculated by the A-logVA function regression method (Z =-8.688,P＜0.01 ).And the correlation indices of LogMAR visual acuity curves obtained by the A-logVA function was 0.733 and that obtained by the A-SP function was 0.715.The positive correlation was found between the subjective LogMAR acuity and that calculated by the A-SP regression method (r=0.700,P＜ 0.01 ) and between the subjective LogMAR acuity and LogMAR acuity calculated by the A-logVA regression method (r=0.710,P＜0.01 ).SVEP LogMAR acuity from A-SP function regression method was significantly different from the LogMAR acuity from A-logVA function regression method (Z=-8.748,P＜0.01 ).No significant differences of VA LogMAR were found in gender,eyes,type of disease and age(x2 =2.171,P=0.338;x2 =0.976,P=0.614;x2 =6.032,P=0.420;x2 =14.720,P=0.257 ).Conclusions SVEP can obtain the visual outcome in human.The amplitude-logVA function regression method is more accurate in extrapolating SVEP acuity.

Objective Based on the observation of the changes of symptoms, histopathology, visceral sensitivity, mast cell activation, autophagy, and Beclin-1 and Claudin-2 expression in rats, we established and evaluated a new rat model of diarrhea-predominant irritable bowel syndrome (D-IBS) induced by restraint-stress combined with capsaicin (CAP) administration.Methods Forty healthy 5-week old male Sprague Dawley (SD) rats were randomly divided into normal group, model group I, model group II and model group III, with 10 rats in each group.The D-IBS model was established by restraint-stress combined with intragastric administration of CAP (2 mL/100 g body weight, 0.125% in group I, 0.250% in group II, 0.500% in group III), tail clipping and forelimb restriction for 30 minutes every day for 2 weeks.The rats in the control group were treated with saline for 2 weeks.The number of contraction of abdominal wall and arched back were measured by Power Lab instrument.The mast cell activation was detected using aldehyde-magenta-orange G staining.Light and electron microscopic examinations were performed to detect the morphology and autophagy of colonic tissues.The expressions of Beclin-1 and Claudin-2 in the colonic mucosa were detected by streptavidin-biotin complex (SABC) immunohistochemical staining.Results All rats in the model group III died during the experiment.Compared with the control group and model group I, the stool frequency was increased and the visceral sensitivity threshold decreased in the model group II, and there were statistically significant differences between the model group II and the control and model groups I (P < 0.05).The colonic mucosa, mucosal epithelium and glands in each group showed normal morphology and there was no submucosal vasodilatation and diffuse inflammatory cell infiltration.Except for the control group, round purple-reddish staining spots were observed in the rat mucosal stroma or submucosa in the model groups I and II, indicating an increased expression of mast cells.The autophagy, expressions of Beclin-1 and Claudin-2 in the colonic epithelium were significantly increased in the model group II compared with control group and model group I (P< 0.05).Conclusions The model of D-IBS induced by restraint-stress combined with capsaicin is characterized by increased diarrhea, visceral hypersensitivity, increased mast cell expression and autophagy of intestinal epithelial cells, and disruption of the intestinal mucosal barrier.This model is simple to set up and shows similar symptoms of human irritable bowel syndrome.Therefore, it is worthy of popularization and application.

Construction of a successful near infrared analysis model is a complex task. It spends a lot of manpower and material resources, and is restricted by sample collection and model optimization. So it is important to study on the extended application of the existing near infrared (NIR) models. In this paper, cephradine capsules universal quantitative model was used as an example to study on the feasibility of its extended application. Slope/bias correction and piecewise direct standardization correction methods were used to make the universal model to fit to predict the intermediates in manufacturing processes of cephradine capsules, such as the content of powder blend or granules. The results showed that the corrected NIR universal quantitative model can be used for process control although the results of the model correction by slope/bias or piecewise direct standardization were not as good as that of model updating. And it also indicated that the model corrected by slope/bias is better than that by piecewise direct standardization. Model correction provided a new application for NIR universal models in process control.
