In order to make sure whether Panax notoginseng is sensitive to chloridion and guide fertilization in planting of P. notoginseng, the effects of the different proportion of potassium chloride (KCl) and potassium sulfate (K2SO4) on the yield, quality of P. notoginseng were studied. The results showed that K fertilizer significantly improved the growth of P. notoginseng and increased the biomass per plant or per pot and the content of N, P, K and the content of saponin. In cases of conditions such as potassium, and the effects of K2SO4 on increasing the petiole length, leaf size, rhizome length, root length, and content and accumulation of Ginsenoside Rg1 were better than those of KCl. While compared with K2SO4, KCl was more conducive to augmenting height, root width, the biomass of shoot, rhizome, root and the content of Ginsenoside Rb1 and Rd. There was not remarkable difference in agronomic characters, biomass and the content of N, P, K among KCl, K2SO4 and the combination of KCl and K2SO4. However, the content of saponin of the treatment with combination of KCl and K2SO4 was significant higher than that of single KCl or K2SO4 treatments. K fertilizer significantly increased yield and the content of saponins. And P. notoginseng was not sensitive to chloridion. KCl increased the yield and the content of saponins of P. notoginseng as well as K2SO4, and the combination treatment was superior to single treatment. It is recommended that the KCl should be adopted in production, to reduce the cost of potash fertilizer.

Objective To determine whether intermittence irradiation of single blue or white light have an adverse effect on the DNA of newborn infants with hyperbilirubinemia by examining the sister chromatid exchange(SCE)frequency of peripheral blood lymphocytes.Methods The frequency of SCE in lymphocytes of 40 icteric infants treated by different phototherapy(PT) methods was a nalyzed by sister chromatid differetance staining technique (SCD).The patients receiving PT were divided into three groups according to two methods of PT,group A:single blue light,20 cases; group B:single white light,20 cases.Results 1.In group A, there was no difference between the levels of SCE before and after therapy within 3 days;but after 4 days, the levels of SCE increased.2.Obvious changes were observed in group B,and the frequency of SCE increased after 1 day and increased significantly in a dose-dependant manner.3.After treatment, the SCE frequency of group B was higher than that of group A.Conclusions PT has mutagenic effect on newborns with hyperbilirubinemia. The effect of single white light on peripheral blood lymphocytes of neonates is more significant.

Objective To study the significance of the sample S/Co ratio when using a domestic reagent for anti-hepatitis C virus(HCV)antibody detection and to explore the procedure and standard of anti-HCV antibody diagnosis by using this domestic reagent.Methods Anti-HCV antibody was detected in 295 000 blood donors by a domestic anti-HCV reagent with enzyme-linked immunosorbent assay(ELISA)method and the reactive samples were tested again by ortho anti-HCV antibody reagent.The samples which anti-HCV antibodies were determined as positive by ortho anti-HCV rea- gent were examined by recombinant immunoblot assay(RIBA)reagent and 106 samples of them were also tested for HCV RNA.Results Six hundred and eighty-one samples were reactive in 295 000 samples screened by the domestic ELISA reagent,the reactive ratio was 0.23 %.Among the reactive samples screened by the domestic ELISA reagent,367 samples were determined as positive by ortho anti-HCV reagent while 66.2% of them showed a S/Co ratio≥3.8.The consistency rate between positive results determined by the domestic reagent and RIBA reagent respectively was 53.8%.For the samples showing S/Co ratio≥3.8 by ortho anti-HCV reagent,94.2% had a S/Co ratio≥8.0 when using the domestic ELISA reagent,while the percentage of samples showing S/Co ratio

OBJECTIVEIn order to improve the irrigation for Panax notginseng growing seedlings, different mulching ways were carried out to investigate the effects of double mulching.

METHODField experiment was applied to study soil moisture, soil temperature and bulk density of different mulching ways while the germination rate and seedlings growth also were investigated.

RESULTCompared with the traditional single mulching with pine leaves or straw, double mulching using plastic film combined with pine leaves or straw could reduce 2/3 volumes of irrigation at the early seedling time Double mulching treatments didn't need to irrigate for 40 days from seeding to germination, and kept soil moisture and temperature steady at whole seedling time about 30% and 9.0-16.6 degrees C, respectively. The steady soil moisture and temperature benefited to resist late spring cold and germinate earlier while kept germination regularly, higher rate and seedlings quality. In contrast, single mulching using pine leaves or straw had poor soil moisture and temperature preserving, needed to irrigate every 12-day, meanwhile dropped the germination and booming time 14 days and 24-26 days, respectively, reduced germination rate about 11.3%-8.7%. However, single pine leaves mulching was better than straw mulching. In addition, though better effects of soil moisture and temperature preserving as well as earlier and higher rate of germination with single plastic films mulching had, some disadvantages had also been observed, such as daily soil temperature changed greatly, seedling bed soil hardened easily, more moss and weeds resulted difficulty in later management.

CONCLUSIONTo the purpose of saving water and labor as well as getting higher germination rate and seedlings quality, double mulching using plastic films combined pine leaves at the early time and single mulching removing plastic films at the later time is suggested to apply in the growing seedlings of P. notoginseng.

Objective: To explore the determinants for health-seeking behavior of the residents after cough for more than 3 weeks in Yiwu, Zhejiang Province, in order to provide reference for prevention and control of respiratory diseases. Methods: A multi-stage cluster random sampling method was used to recruit the community residents aged 5 years and above in Yiwu. A face-to-face questionnaire survey was conducted to collect demographic information, features of cough and health-seeking behaviors in the past month. The multivariate logistic regression model was employed to analyze the associated factors for health-seeking behavior after a cough for more than 3 weeks. Results: Among 6 374 residents investigated, 152 cases had a cough for more than 3 weeks in the past month, accounting for 2.48%. They were( 45.00±21.15 ) years old, including 70 ( 46.05% ) males and 82 ( 53.95% ) females. About 58.55% ( 89 ) of them sought medical treatment. The results of multivariate logistic regression analysis showed that females ( OR=2.100, 95%CI: 1.005-4.391 ), middle school education level ( OR=0.406, 95%CI: 0.168-0.983 ), family annual income of 100 000 to 199 999 yuan ( OR=2.993, 95%CI: 1.215-7.373 ) were associated factors for health-seeking behavior after a cough for more than 3 weeks. Conclusion The rate of health-seeking behavior after a cough for more than 3 weeks among the residents in Yiwu is 58.55%, which is associated with gender, education level and income.

Chinese Pharmacopoeia I (2010 edition) covers dosage and usage of traditional Chinese medicinal herbs and decoction pieces, and provides dosage ranges of most of decoction pieces. By using the descriptive statistical method, the article discusses the distribution of maximum dosage, minimum dosage and dosage range of decoction pieces set forth in Chinese Pharmacopoeia, and compares toxic drugs and non-toxic drugs. Altogether 617 drugs are included into the study. Except for 16 decoction pieces whose dosages are not clear, all of the remaining decoction pieces are covered by Chinese Pharmacopoeia, with the maximum common dosage, minimum common dosage and dosage range of 3, 10 and 6 g. Upon comparison, we discovered that Chinese Pharmacopoeia sets stricter standards for toxic drugs than non-toxic drugs. Compared with dosages in classical prescriptions and actual clinical usages, dosage ranges described in Chinese Pharmacopoeia are much narrower. There is no significant difference between drugs that can be used as foods or healthcare foods and other drugs according to Chinese Pharmacopoeia.

OBJECTIVETo study the clinical characteristics of children who suffered from Streptococcus pneumoniae (SP) septicemia and the drug sensitivity of SP strains.

METHODSA retrospective analysis was performed on the clinical data of 25 children with SP septicemia between January 2009 and December 2012.

RESULTSOf the 25 cases, 16 (64%) were aged under 2 years, 5 (20%) were aged 2-5 years, and 4 (16%) were aged over 5 years. Fourteen cases (56%) were complicated by infection of other organs, and 5 cases (20%) had underlying chronic diseases. Fever was the most common clinical manifestation, and the majority presented with remittent fever. Eight patients with pneumonia or pyothorax had pulmonary symptoms. Five patients with purulent meningitis had neurological symptoms, five cases had hepatosplenomegaly and two cases had septic shock. Nineteen cases (76%, 19/25) had significantly elevated white blood cell (WBC) counts, twenty-one cases (84%, 21/25) had significantly elevated serum C-reactive protein (CRP) levels, and eight cases (50%, 8/16) had significantly elevated serum procalcitonin (PCT) levels. The drug sensitivity analysis showed that invasive SP had high resistance rates to penicillin (96%), clindamycin hydrochloride (88%) and erythromycin (84%), and it was completely sensitive to imipenem, vancomycin, levofloxacin and linezolid. The multi-drug resistance rate of invasive SP was up to 88%. Twenty-three cases (92%) were cured or improved after active treatment.

CONCLUSIONSSP septicemia is commonly seen in children aged under 2 years. The most common clinical manifestation is fever, accompanied by elevated WBC count, CRP level and PCT level, and it is usually complicated by pulmonary or brain infection. Resistance to multiple antibiotics is very common in SP strains, so it is important to properly use antibiotics according to drug sensitivity test results. Patients who receive active treatment have a good clinical outcome.
