Objective To evaluate the clinical efficacy and safety ofShugan Liqi Qingqiu Decoction in the treatment of allergic rhinitis.Methods Totally 74 patients were randomly divided into treatment group and control group in a 1:1 ratio. The treatment group received the prescription ofShuganLiqiQingqiu Decoction, and control group was given loratadine tablets orally, 7 days as a course of treatment and 3 courses successive. After treatment, the visual analogue scale (VAS), Rhinocoujunctivitis Quality of Life Questionaire (RQLQ), Specific IgE (SIgE) values and total effective rate were measured to evaluate the clinical efficacy, and the total number of cases of adverse reactions was statistically analyzed.Results After all the patients were researched, the total effective rate of treatment group was 86.49% (32/37) in the treatment group and 89.19% (33/37) in control group, without statistical difference (P>0.05). There was statistical difference in VAS and RQLQ between before and after treatment in the two groups (P<0.05). After treatment, there was no statistical difference (P>0.05) in VAS and was statistical difference in RQLQ (P<0.05) in the two groups. There was no statistical difference (P>0.05) in SIgE in the treatment group, and was statistical difference (P<0.05) in control group. There was no significant difference (P>0.05) in SIgE between the two groups after treatment. There was no adverse reaction except for 2 patients in the treatment group with mild diarrhea. Conclusion ShuganLiqiQingqiu Decoction has good clinical efficacy and safety for the treatment of allergic rhinitis.

Lectin from green marine algae Enteromorpha intestinalis (EIL) was isolated by extraction with PBS, followed by ammonium sulfate fraction and a combination of ion-exchange chromatography on DEAE-52 fiber and gel filtration on SephadexG-200. Lectin showed single band on both PAGE and isoelectrofocusing electrophoresis. Its isoelectric point was 8.9 and molecular weight was 17783 tested on SephadexG-200. EIL displayed some agglutination activities with Chlamydomonas and erythrocytes of rabbit, common carp, crucian carp and human (A, B, AB, O), but the maximum agglutination was with crucian carp. The hemagglutinating activity for rabbit erythrocyte could not be inhibited by D-fructose, D-galactose, glucose, sucrose, mannose, lactose, bovine-thyroglobulin, egg albumin and gamma-globulin. The hemagglutinating activity of lectin would be showed at pH 4.0~10.2, and more potent at pH 6.9~8.0. The hemagglutinating activity was not affected at 90℃ for 1h, so it could be said that the lectin had high heat resistance.

Recently, neuromyelitis optica spectrum disorders (NMOSD) appear to be a multi-organ disorder, however, the involvement of myocardium in NMOSD is extremely rare. In the present article, we present a young girl who manifested bilateral optic neuritis, area postrema syndrome, brainstem syndrome and transverse myelitis, as well as tachycardia, abnormal electrocardiograph, moderate elevation of myocardial biomarker and regional wall movement abnormalities, which confirmed the diagnosis of Takotsubo cardiomyopathy associated with NMOSD. The neurological deficits along with myocardial injury were recovered soon after the administration of intravenous methylprednisolone and intravenous immunogloblin. This is a rare case that should be paid attention and by which can not only broaden the symptom spectrum of NMOSD, but can also provide novel visions for further investigating the mechanism of organs damage.

OBJECTIVETo investigate the effect of emodin on proliferation and cell cycle distribution of human oral squamous carcinoma cells in vitro.

METHODSCultured human oral squamous carcinoma Tca8113 cells were treated with 2.5, 5, 10, 20, 40, 60 and 80 µmol/L emodin for 24, 48 or 72 h, with the cells treated with 0.1% DMSO as control. MTT assay and flow cytometry were used to evaluate the changes in cell proliferation and cell cycle distribution, respectively. Western blotting was employed to analyze the changes in the expression levels of the cell cycle-related proteins CDK2, cyclin E and P21 after emodin treatment.

RESULTSEmodin significantly inhibited the growth and proliferation of Tca8113 cells within 72 h in a time- and dose-dependent manner, and caused cell cycle arrest in G0-G1 phase. Western blotting revealed that emodin treatment significantly lowered the expression levels of CDK2, cyclin E and P21 proteins in Tca8113 cells (P<0.05).

CONCLUSIONEmodin can inhibit the proliferation of Tca8113 cells and affect their cell cycle distribution possibly by inhibiting the signaling pathways of cell cycle regulation.

OBJECTIVE: To explore the clinical, electrophysiological and imaging features of a patient with Krabbe disease caused by GALC mutation. METHODS: A comprehensive analysis including clinical investigation and genetic testing was carried out. RESULTS: The patient presented with peripheral neuropathy with electrophysiological anomaly suggestive of asymmetric demyelinating neuropathy. Brain imaging revealed leukoencephalopathy. Genetic analysis has identified compound heterozygous mutations in exons 5 and 11 of the GALC gene, namely c.461C>A and c.1244G>A. CONCLUSION Krabbe disease is a group of disorders featuring substantial phenotypic heterogeneity. Genetic and enzyme testing has become indispensable for accurate diagnosis for this disease.

This study was to develop a new method for detecting circulating tumor cells (CTCs) with high sensitivity and specificity, therefore to detect the colorectal cancer as early as possible for improving the detection rate of the disease. To this end, we prepared some micro-column structure microchips modified with graphite oxide-streptavidin (GO-SA) on the surface of microchips, further coupled with a broad-spectrum primary antibody (antibody1, Ab₁), anti-epithelial cell adhesion molecule (anti-EpCAM) monoclonal antibody to capture CTCs. Besides, carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) were coupled with colorectal cancer related antibody as specific antibody 2 (Ab₂) to prepare complex. The sandwich structure consisting of Ab₁-CTCs-Ab₂ was constructed by the microchip for capturing CTCs. And the electrochemical workstation was used to detect and verify its high sensitivity and specificity. Results showed that the combination of immunosensor and micro-nano technology has greatly improved the detection sensitivity and specificity of the immunosensor. And we also verified the feasibility of the immunosensor for clinical blood sample detection, and successfully recognitized detection and quantization of CTCs in peripheral blood of colorectal cancer patients by this immunosensor. In conclusion, the super sandwich immunosensor based on micro-nano technology provides a new way for the detection of CTCs, which has potential application value in clinical diagnosis and real-time monitoring of disease.

Cyclospora cayetanensis is a foodborne and waterborne pathogen that causes endemic and epidemic human diarrhea worldwide. A few epidemiological studies regarding C. cayetanensis infections in China have been conducted. During 2013, a total of 291 stool specimens were collected from patients with diarrhea at a hospital in urban Shanghai. C. cayetanensis was not detected in any of the stool specimens by traditional microscopy, whereas five stool specimens (1.72%, 5/291) were positive by PCR. These positive cases confirmed by molecular technology were all in the adult group (mean age 27.8 years; 2.94%, 5/170) with watery diarrhea. Marked infection occurred in the rainy season of May and July. Sequence and phylogenetic analyses of the partial 18S rRNA genes of C. cayetanensis isolated showed intra-species diversity of this parasite. This study showed, for the first time, that C. cayetanensis is a pathogen in outpatients with diarrhea in Shanghai, albeit at a low level. However, the transmission dynamics of this parasite in these patients remain uncertain.
