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).

Herpes simplex virus type Ⅰ(HSV-1) is a common pathogen, and human is the only natural host of it.Following a period of lytic replication in epithelial cells, HSV-1 enters axon terminals of sensory neurons and then travels via retrograde transport to the sensory ganglia where latency can be established.Upon the stimulation of some stressors, the latent virus can reactivate, leading to recurrent diseases.Therefore, to clarify the mechanism of HSV-1 latent infection and stress-induced reactivation will offer new insights into the prevention, treatment and control of HSV-1 infection.In this review, we describes the mechanisms underlying HSV-1 latent infection and stress-induced reactivation.

Objectives To detect anti-basement membrane zone(BMZ)antibodies in systemic lupus ery-thematosus(SLE)patients and to explore its association with clinical manifestations.Methods Anti-BMZ anti-bodies were examined by indirect immunofluorescence in the sera of70patients with SLE.The correlation between anti-BMZ antibodies and clinical data of SLE was analyzed.Results Anti-BMZ antibodies could be found in the sera of about70%SLE patients,including IgG,IgM,IgA.They predominantly bound to the epidermis,but also bound to the dermis or both.The positive rate of anti-BMZ antibodies was significantly higher in patients with skin lesions than that of patients without skin lesions.There is no significant difference between the two groups in ac-tive and remission,kidney involvement,arthritis,alopecia,photoallergy,positive anti-dsDNA antibodies and the posi-tive rate of anti-BMZ antibodies.Conclusion Anti-BMZ antibodies presents in the sera of SLE patients with high positive rate.It is correlated with the development of skin lesions of SLE patients,but not with the activity of SLE,other clinical manifestations and anti-dsDNA antibodies.Anti-BMZ antibodies may be involved in the pathogenlic mechanism of the development of skin lesions in SLE patients.

Objective To explore the optimal method of treatment for radiation proctitis by keeping coloclysis with traditional Chinese medicine (TCM), including administation temperature, infusion time, dosage and catheter depth. Methods The orthogonal experimental design was adopted. Sixty-three patients with radiation proctitis were randomly divided into 9 groups, and they were under enema for 6 weeks according to different test conditions. TCM syndrome score, radiation injury effect and Karnofsky scores were set as evaluation indexes. An orthogonal design and analysis of variance were conducted for optimization. The best technical schemes for traditional Chinese herb in treating radiation proctitis were obtained. Results The obtained optimum methods are:drug temperature of (39±0.5)℃, infusion time of 30 minutes, dosage of 100 mL, catheter depth of 20 cm. Conclusion The optimal scheme of enema for the treatment of radiation proctitis is reasonable and feasible.

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.
