Chinese Journal of Information on Traditional Chinese Medicine 2017;24(12):122-124
This article introduced the application of spleen method in children with pulmonary diseases. It pointed out that for children with acute pulmonary infectious diseases, clearing heat and reducing phlegm should be the treatment for temporary symptoms, strengthening the function of spleen and stomach should be the treatment for essence; recurrent pulmonary diseases should be treated with tonifying spleen to support right qi and adjust ying and wei to strengthen immune system; cough after infection can be treated with reducing phlegm to dispel rest pathogenesis, and mainly strengthen the function of spleen and harmonize zhong. In this article, the typical cases were described, which led to the importance of spleen deficiency in lung disease. Spleen method for treatment of lung diseases has a certain efficacy, which is worth further clinical study.

Ten compounds, including seven sesquiterpenes, two phenols and one phenylpropanoid, were isolated from the roots of Illicium majus by means of silica gel, ODS, Sephadex LH-20, and preparative HPLC. On analysis of MS and NMR spectroscopic data , their structures were established as cycloparviflorolide (1), cycloparvifloralone (2), tashironin (3), tashironin A (4), anislactone A(5), anislactone B (6), pseudomajucin (7), syringaldehyde (8), methyl-4-hydroxy-3, 5-dimethoxybenzoate (9), and (E)-3-methoxy-4,5-methylenedioxycinnamic alchol (10), respectively. Compounds 1-4 and 8-10 were first isolated from this plant. In the in vitro assays, at a concentration of 1.0 x 10(-5) mol x L(-1), compounds 5 and 6 were active against LPS induced NO production in microglia with a inhibition rate of 75.31% and 53.7%, respectively.

OBJECTIVETo evaluate the relationship between circulating levels of insulin-like growth factor-1 (IGF-1), IGF-binding protein-3 (IGFBP-3) and colorectal cancer.
METHODSA meta-analysis of 6 epidemiological studies on insulin-like growth factors and risk of colorectal cancer were performed.
RESULTSThe pooled odds ratio (OR) of IGF-1 and IGFBP-3 were 1.56 (95% CI: 1.14-2.13) and 0.78 (95% CI: 0.43-1.44) respectively. According to the results from different measurements (enzyme-linked immunoabsorbent assay and immunoradiometric assay), the pooled OR were 1.92 and 1.23 for IGF-1, 0.46 and 1.44 for IGFBP-3 respectively.
CONCLUSIONHigh serum levels of IGF-1 were independent risk factors of colorectal cancer but the OR of IGFBP-3 was not statistically significant. The heterogeneity between studies on IGFBP-3 and colorectal cancer was caused by different measurements used, but there was still a need to conduct simultaneous large size study under 2 different measurements for further conclusion.

OBJECTIVETo study the clinical and laboratory characteristics of adult Japanese encephalitis (JE) patients in a JE outbreak in Yuncheng, Shanxi Province in 2006.
METHODAll the clinical data from the Second People's Hospital in Yuncheng city were analyzed, part of patients' sera and cerebrospinal fluid were tested by serology and RT-PCR.
RESULTSThe majority of patients were middle-aged and elderly, 77.8% (35/45) of the total cases were more than 40 years old. Severe and fulminating type cases accounted for 60.0% (27/45). Most patients had underlying diseases. IgM antibody to JE virus (JEV) in serum was positive in each of the 45 patients analyzed and 4-fold or greater rise in sera neutralization antibody titer were found in convalescent serum. JEV nucleic acid was positive in part of cerebrospinal fluid specimens.
CONCLUSIONViral encephalitis emerged in Yuncheng city, Shanxi Province was Japanese encephalitis B, and most of the cases belonged to elderly group.

5 strains of virus isolated from Culex tritaeniorhynchus, Anopheles sinensis and Armigeres subalbatus, which caused cytopathic effect in C6/36 cells, had been obtained in the survey of arboviruses in Northwestern Yunnan Province. China. The virus particles displayed 70 nanometers diameter (n=7) with no envelope but spikes on the surfaces. RNA-PAGE of the genomes of the isolates showed 6-5-1 profile. A fragment of the 12th segment sequence was amplified by a pair of specific primers for Kadipiro virus strain JKT-7075 in RT-PCR. The full length of the 12th segment was 758 nucleotides, BLAST analysis revealed the highest identity was 90% to JKT-7075. Phylogenetic analysis demonstrated that the isolates appeared to be Kadipiro viruses (Family Reoviridae). It was the first report of kadipiro virus isolation in China.

Objective To investigate whether elevated baseline levels of high sensitivity C-Reactive Protein (hsCRP) and neutrophil (NE) are associated with an increased risk of breast cancer in Kailuan female cohort. Methods Females from Kailuan cohort (2006-2007) were included in this study. Information on check-up, hsCRP and NE were collected at baseline for all subjects. Multivariable Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (95%CI) of association between baseline hsCRP and NE values and breast cancer risk. Results By December 31, 2015, a total of 18 866 participants were enrolled in this study. During the follow-up, 183 new cases of breast cancer were observed. All participants were divided into three groups according to the level of hsCRP (<1 mg/L, 1-3 mg/L and >3 mg/L). The cumulative incidence of breast cancer were 829/105, 1 211/105 and 1 495/105 in these 3 groups, respectively ( 2=12.08, P=0.002). Compared with participants with lower hsCRP levels (<1 mg/L), individuals with the highest hsCRP (>3 mg/L) levels had significantly increased risk of breast cancer (HR=1.71,95%CI: 1.18-2.47, P=0.005), howerver, we didn’t find the statistically significant association between NE level (<3.70×109/Lvs. ≥3.70×109/L) and the risk of brease cancer (P>0.05). Conclusions Elevated levels of hsCRP at baseline might increase the risk of breast cancer in females.

OBJECTIVEIn mid-July 2005, five patients presented with septic shock to a hospital in Ziyang city in Sichuan, China, to identify the etiology of the unknown reason disease, an epidemiological, clinical, and laboratory study were conducted.
METHODSAn enhanced surveillance program were established in Sichuan, the following activities were introduced: active case finding in Sichuan of (a) laboratory diagnosed Streptococcus suis infection and (b) clinically diagnosed probable cases with exposure history; supplemented by (c) monitoring reports on meningococcal meningitis. Streptococcus suis serotype 2 infection was confirmed by culture and biochemical reactions, followed by sequencing for specific genes for serotype and virulence factors.
RESULTSFrom June 10 to August 21, 2005, 68 laboratory confirmed cases of human Streptococcus suis infections were reported. All were villagers who gave a history of direct exposure to deceased or sick pigs in their backyards where slaughtering was performed. Twenty six (38%) presented with toxic shock syndrome of which 15 (58%) died. Other presentations were septicaemia or meningitis. All isolates were tested positive for genes for tuf, species-specific 16S rRNA, cps2J, mrp, ef and sly. There were 136 clinically diagnosed probable cases with similar exposure history but incomplete laboratory investigations.
CONCLUSIONAn outbreak of human Streptococcus suis serotype 2 infections occurred in villagers after direct exposure to deceased or sick pigs in Sichuan. Prohibition of slaughtering in backyards brought the outbreak to a halt. A virulent strain of the bacteria is speculated to be in circulation, and is responsible for the unusual presentation of toxic shock syndrome with high case fatality.

To study Ginkgo biloba leaves in different producing area, we establish an HPLC method for the simultaneously determination of seven flavonoids glycosides and four biflavonoids in G. biloba leaves. The analysis was performed on an Agilent ZORBAX SB-C₁₈ column(4.6 mm×250 mm, 5 μm) wich acetonitrile, and 0.4% phosphoric acid as mobile phase at flow rate of 1 mL•min⁻¹ in a gradient edution, and the detection was carried out at 254 nm.The calibration curves of the seven flavonoids glycosides and four biflavonoids had a good linearitiy with good recoveries. The established HPLC method is simple, rapid, accurate, reliable, and sensitive, and can be applied to the identification and quality control of G. biloba leaves.
