OBJECTIVE:
To investigate whether the allergic factors impact the severity of chronic rhinosinusitis or not, further more, to explore the relationship between allergic rhinitis and chronic rhinosinusitis.
METHOD:
A retrospective review was done on 103 patients. All of these patients were under functional intranasal endoscopic sinus surgery after expectant treatment is ineffective. We devided the patients into different groups according to the result of skin prick and specific IgE and if there is difference in VAS score, Lund and Kennedy endoscopic score, Lund-Mackay CT score between the groups. We also analysed the symptoms in different chronic rhinosinusitis patients allerged to variant kinds of allergen. The SPSS 17.0 software was used to analyze the data. Statistical analysis was performed by t-test, rank order test or χ2 test.
RESULT:
The duration of the disease, VAS score of nasal blockage, score of Lund-Mackay CT and Lund and Kennedy endoscopic before the operation were in no statistical sense after when compared with the two groups of patients with chronic rhiriosinusitis who grouped according the result of skin prick and specific IgE. The VAS score of facial pressure and loss of smell was higher in patients with chronic rhinosinusitis which the skin prick and specific IgE were positive. The VAS score of nasal discharge was higher in patients with chronic rhinosinusitis who got negative skin prick and specific IgE result. The symptoms of chronic rhinosinusitis improved with operation no matter the group of skin prick and specific IgE positive or negative and VAS score of nasal blockage improved significantly in negative group. The symptoms of sneezing, rhinorrhoea and rhinocnesmus improved after operation among the chronic rhinosinusitis patients with skin prick and specific IgE. The number of cockroach allergy is larger among the patients with chronic rhinosinusitis without polyps than the one among the patients with chronic rhinosinusitis with polyps.
CONCLUSION
Allergic factor didn't impact much the severity of chronic rhinosinusitis patients who were failed in expectant treatment, besidesthe postoperative outcomes showed that only influence the severity of nasal discharge, facial pressure and loss of smell. Different kinds of allergen were found between the patients of chronic rhinosinusitis with or without polyps. No significantly functional endoscopic sinusitis sugrery outcome were related to the allergic factor. But the allergic factor may interfere the remission of nasal discharge after surgery.

The study is aimed to make the most of available space of Dendrobium officinale cultivation facility, reveal the yield and functional components variation of stereoscopic cultivated D. officinale, and improve quality, yield and efficiency. The agronomic traits and yield variation of stereoscopic cultivated D. officinale were studied by operating field experiment. The content of polysaccharide and extractum were determined by using phenol-sulfuric acid method and 2010 edition of "Chinese Pharmacopoeia" Appendix X A. The results showed that the land utilization of stereoscopic cultivated D. officinale increased 2.74 times, the stems, leaves and their total fresh or dry weight in unit area of stereoscopic cultivated D. officinale were all heavier than those of the ground cultivated ones. There was no significant difference in polysaccharide content between stereoscopic cultivation and ground cultivation. But the extractum content and total content of polysaccharide and extractum were significantly higher than those of the ground cultivated ones. In additional, the polysaccharide content and total content of polysaccharide and extractum from the top two levels of stereoscopic culture matrix were significantly higher than that of the ones from the other levels and ground cultivation. Steroscopic cultivation can effectively improves the utilization of space and yield, while the total content of polysaccharides and extractum were significantly higher than that of the ground cultivated ones. The significant difference in Dendrobium polysaccharides among the plants from different height of stereo- scopic culture matrix may be associated with light factor.

A novel targeting drug carrier (FA-BO-PAMAM) based on the PAMAM G5 dendrimer modified with borneol (BO) and folic acid (FA) molecules on the periphery and doxorubicin (DOX) loaded in the interior was designed and prepared to achieve the purposes of enhancing the blood-brain barrier (BBB) transportation and improving the drug accumulation in the glioma cells. 1H NMR was used to confirm the synthesis of FA-BO-PAMAM; its morphology and mean size were analyzed by dynamic light scattering (DLS) and transmission electron microscope (TEM). Based on the HBMEC and C6 cells, cytotoxicity assay, transport across the BBB, cellular uptake and anti-tumor activity in vitro were investigated to evaluate the properties of nanocarriers in vitro. The results showed that the nanocarrier of FA-BO-PAMAM was successfully synthesized, which was spherical in morphology with the average size of (22.28 ± 0.42) nm, and zeta potential of (7.6 ± 0.89) mV. Cytotoxicity and transport across the BBB assay showed that BO-modified conjugates decreased the cytotoxicity of PAMAM against both HBMEC and C6 cells and exhibited higher BBB transportation ability than BO-unmodified conjugates; moreover, modification with FA increased the total uptake of DOX by C6 cells and enhanced the cytotoxicity of DOX-polymer against C6 cells. Therefore, FA-BO-PAMAM is a promising nanodrug delivery system in employing PAMAM as a drug carrier and treatment for brain glioma.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

OBJECTIVETo explore the value of dual-time-point (18)F-fluorodeoxyglucose integrated positron emission and computed tomography ((18)F-FDG PET-CT) in differentiation of malignant from benign gastrointestinal diseases.
METHODSSixty five patients with suspected gastrointestinal lesions underwent dual-time-point (18)F-FDG PET-CT imaging. Standardized uptake value (SUV) was calculated for semi-quantitative assessment. The SUV of the two acquisitions were signed SUV(early) and SUV(delayed), respectively. Then the change of SUVmax (ΔSUVmax) was calculated. The ROC curves of the SUV(early), SUV(delayed) and ΔSUV were drawn to find the best cut-off point value for differential diagnosis, and then the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated, respectively.
RESULTSOf the malignant lesions, the SUVmax in delayed imaging were significantly higher than those in early imaging, while there were no significant differences of SUVmax between the two images of the benign lesions. The ΔSUVmax of the malignant lesions were significantly higher than that of the benign ones. Taking the SUVmax higher than 9.2 in early imaging as positive diagnostic criteria, the sensitivity was 72.7%, the specificity was 85.7%, the positive predictive value was 91.4%, the negative predictive value was 60.0%, and the accuracy was 76.9%. Taking the SUVmax higher than 10.9 in delayed imaging as positive diagnostic criteria, the sensitivity was 75.0%, the specificity was 90.5%, the positive predictive value was 94.3%, the negative predictive value was 63.3%, and the accuracy was 80.0%. Taking the ΔSUVmax higher than 5.1% as positive diagnostic criteria, the sensitivity was 95.5%, the specificity was 85.7%, the positive predictive value was 93.3%, the negative predictive value was 90.0%, and the accuracy was 92.3%. The accuracy of dual-time-point (18)F-FDG PET-CT imaging was significantly higher than that of single-time point (18)F-FDG PET-CT imaging.
CONCLUSIONDual-time-point (18)F-FDG PET-CT imaging is a useful method for differentiating malignant from benign gastrointestinal diseases, and it is superior to the single-time point (18)F-FDG PET-CT imaging.

To study relevant risk factors of Shenmai injection induced adverse reactions by using Logistic model and ROC curve, and made the prediction for the occurrence of relevant adverse reactions/events. Case data of patients treated with Shenmai injection were collected by using the prospective, multi-center, large-sample, nested-case control method, in order to analyze the risk factors of Shenmai injection-induced adverse reactions/events, establish the logistic model and draw the receiver operating characteristic (ROC) curve for risk factors. During the study, 7632 patients (including 3 477 males and 4 155 females) were included, and eight of them suffered adverse reactions/events. Based on a multi-factor Logistic model analysis, the age (> or = 50 years) (OR = 5.061, 95% CI: 2.197-7.924; P = 0.001), the total number of medication days (OR = -1.020, 95% CI: -l.652 - 0.388; P = 0.002) and the single dose (OR = 0.245, 95% CI: 0.127-0.364; P = 0.000) were significant independent risk factors for Shenmai injection-induced adverse reactions/events. According to the results, ROC curves were drawn with age (> or = 50 years), the total number of days of inedication and single dose; The area under ROC curves the joint predictor (0.9753, 95% CI: 0.9443-1.000, P < 0.005) was larger than that of the other three single indexes, with a higher risk prediction value. The independent risk factors for Shenmai injection-induced adverse reactions/events included the age (> or = 50 years), the total number of days of medication and single dose. In clinical practice, the age (> or = 50 years), the total number of days of medication and the medication dose can be substituted in the joint predictor calculation formula (P = 1 / [1 + e(-(-21.58 + 5.061 x Xage - 1.020 x Xd + 0.245 x X(mL)] to predict the potential adverse reactions of patients and adjust the dosage regimen.
