This paper reports the results of 15 cases of chronic hepatitis B treated with alpha-inter -feron (?-IFN) combined with silybum marinanum compound at a small dose (?-IFN 5000 units/day)in a long treatment course(3-6 months). The cure rate was 66.6% in the treatment group and 33.3% in the placebo group. The amount of ?-IFN in the serum of the patients was determined before and after treatment, but no ?-IFN in the serum was detected before treatment, ?-IFN elevated to 5-40 units/ml after treatment for 3-7 months. However, it would drop when the treatment was stopped. The therapeutic effect was remarkable when the amount of ?-IFN in the serum was increased. The results indicate that the anti-viral drug(IFN)combined with silyoum marinanum compound may be used to cure chronic hepatitis B.

Objective: To establish a UPLC fingerprint method and a method for the content determination of 3,5-O-dicaffeoylquinic acid of Aucklandiae Radix, and provide a comprehensive evaluation of the drug from different habitats. Methods: UPLC analysis was performed on a YMC Trait C18 (100 mm × 2.1 mm, 1.9 μm), with a mobile phase consisting of acetonitrile-0.05% phosphoric acid at the flow rate of 0.30 mL/min. The fingerprint detection wavelength was 254 nm and the content determination detection wavelength of 3,5-O-dicaffeoylquinic acid was 327 nm, meanwhile, the column temperature was controlled at 30 ℃. Similarity analysis, hierarchical clustering analysis, and principal component analysis were undertaken to investigate the fingerprints of 13 batches of Aucklandiae Radix. Results: UPLC fingerprint of Aucklandiae Radix was established and eight common peaks were designated. The results showed that the quality of the batches of samples were not stable. Samples collected from the same region and different regions both had certain differences, as well as the content determination of 3,5-O-dicaffeoylquinic acid. Conclusion: The proposed method offered a fast, holistic, and effective method for the quality control of Aucklandiae Radix.

OBJECTIVETo explore the cerebral function laterality of acupuncture at left and right Hegu (LI 4) by using functional magnetic resonance imaging (fMRI) and provide objective evidences for side selection of Hegu (LI 4) in the clinical application.

METHODSEighty healthy volunteers were randomly divided into a left-acupoint group and a right-acupoint group, and they were treated with acupuncture at left Hegu (LI 4) and right Hegu (LI 4) respectively. After the arrival of qi, the task-state fMRI data in both groups was collected, and analysis of functional neuroimages (AFNI) software was used to perform intra-group and between-group comparisons. After acupuncture, acupuncture feelings were recorded and MGH acupuncture sensation scale (MASS) was recorded.

RESULTSThe difference of MASS between the two groups was not significant (P>0. 05). The result of left-acupoint group showed an increased signal on right cerebral hemisphere, while the right-acupoint group showed extensive signal changes in both cerebral hemispheres. The analysis between left-acupoint group and retroflex right-acupoint group showed differences in brain areas.

CONCLUSIONSThe central effect of acupuncture at left and right Hegu (LI 4) is dissymmetry, indicating right hemisphere laterality. The right lobus insularis and cingulate gyrus may be the key regions in the acupuncture at Hegu (LI 4).

Objective To investigate the relationship between corneal basal nerve change and type 2 diabetic retinopathy based on confocal laser microscopy.Methods Together 118 patients with type 2 diabetes (T2D) were collected in our hospital from February 2016 to February 2017,including 57 patients with diabetic retinopathy (DR group) and 61 patients without DR (NDR group).For comparison,60 healthy volunteers were selected as the control group.And all the subjects were examined by corneal confocal laser microscopy to analyze the relationship between the morphological parameters of the corneal nerve and clinical variables.Results Corneal nerve fiber density,corneal nerve branch density and corneal nerve branch length in DR group were (20.03 ±4.22) · mm-2,(22.01 ± 7.05) · mm-2 and (9.50 ± 1.76) mm ·mm-2,significantly less than those of the control group and NDR group (all P ＜ 0.05);and corneal nerve fiber curvature was (0.30 ± 0.03),significantly higher than that of the control group and NDR group (all P ＜ 0.05);In DR patients,phase Ⅲ patients had smaller the corneal nerve fiber density,corneal nerve branch density and corneal nerve branch length,but the larger corneal nerve fiber curvature than the phase Ⅰ and Ⅱ patients (all P ＜ 0.05);course of disease of DR group was (12.04 ± 2.48) years,which was significantly higher than that of NDR group (P ＜ 0.05),while fasting C peptide and fasting insulin were (1.41 ± 0.58) μg · L-1 and (20.05 ± 7.91) mU · L-1,respectively,significantly lower than those of NDR group (all P ＜ 0.05);The duration of T2D was negatively correlated with the corneal nerve branch density and corneal nerve branch length (r =-0.322,-0.317,all P ＜0.05);Fasting C peptide was positively correlated with the corneal nerve branch density (r =0.298,P ＜ 0.05),and negatively correlated with the corneal nerve curvature (r =-0.311,P ＜ 0.05).Conclusion Patients with T2D retinopathy have abnormal morphology of corneal nerve.And confocal laser scanning microscopy is conducive to the early detection of microvascular disease in T2D patients with a longer course of disease or a low level of fasting C peptide.

Objective To evaluate the value of the 7-joint ultrasound score (US7) in treatment of rheumatoid arthritis (RA) with Chinese and western medicine.Methods A total of 160 RA patients were divided into 2 groups based on different methods of treatment,including Yi Shen Qing Luo (YSQL) group and western medicine group.The patients were examined by grey scale ultrasound (GSUS) and power Doppler ultrasound (PDUS) with US7 at baseline and after 3 and 6 months later.There were 7 related joints and 5 single factors for scoring in US7 system.The joints included the wrist joints,the second/third metacarpophalangeal joints (MCP Ⅱ/Ⅲ),the second/third proximal interphalangeal joints (PIP Ⅱ / Ⅲ) and the second/fifth metatarsophalangeal joints (MTP Ⅱ/Ⅴ).And the factors included synovitis of GSUS,synovitis of PDUS,myotenositis/tenosynovitis of GSUS,myotenositis/tenosynovitis of PDUS and bone erosion (ES).Meanwhile,the laboratory index included C-reactive protein (C-RP) and erythrocyte sedimentation rate (ESR) were examined.And the clinical indexes as disease activity score in 28 joints (DAS28) were evaluated.Results The statistical differences of synovitis of GSUS,synovitis of PDUS,myotenositis/tenosynovitis of GSUS and myotenositis/tenosynovitis of PDUS scores in US7 system were found in both 2 groups at baseline,3 months and 6 months after treatment (all P＜0.01).There was no statistical difference of ES before and after treatment in all cases (P＞0.05).The factors of US7 were positively correlated with DAS28,C-RP and ESR in different extent.Condusion US7 is a viable tool for examining patients with RA.

Parkinson’ s disease ( PD) is a common disease in central nervous system, for which an effective treatment has yet to be found. The causes of PD include genetic, environmental, aging factors, etc. There is a common factor which can lead to the degeneration of dopaminergic neurons in the substantia:mito-chondrial damage and repair. This paper has summarized the en-vironmental and genetic factors that can cause mitochondrial damage in dopaminergic neurons, and outlined several mitochon-drial repairing pathways ( such as mitophagy) in the treatment of PD. It also analyzes the research situation of utilizing natural medicine in the therapy of PD from the perspective of the mito-chondrial protection.

Objective To discuss the necessity and feasibility of nucleic acid test(NAT)in clinical blood transfusion by the im-plementation of the nucleic acid testing after the ELISA screening of Zhengzhou blood donors.Methods HBV DNA,HCV RNA, HIV RNA were detected by Roche Cobas S201 system and Shanghai kehua screening system,the samples were mixed by 6×166.7μL and 8×180 μL(as one pool)separately.If the mix pool was negative,the result can be issued directly;if the pool was positive, than secondary single sample dectection must be taken and the secondary report was the final result.Results A total of 115 227 blood samples were screened by Roche Cobas S201 system and 130 mix pools were positive,among which 80 pools were reactive by secondary split testing,and the reactive samples were 86,the split ratio was 61.5%,The positive ratio of specimens was 0.75‰.90 359 samples were screened by kehua system,and the mixed pools were 93,among which 31 pools were reactive by secondary split testing,and the reactive samples were 31,the split ratio was 33.4%,The positive ratio of specimens was 0.34‰.So the total num-ber screened by the two systems was 205 586,among which 117 cases were reactive,the total positive ratio of specimens was 0.57‰.And one case was HIV window phase infection.Conclusion NAT could effectively decrease the risk of blood transfusion caused by omission of ELISA and ensure the safety of blood transfusion.
