Abstract
Objective:The aim of this study is to explore the feasibility and clinical effect of tympanoplasty combined with ventilation tube insertion in otitis media.Method: Retrospective analysis of 35 patients with eustachian tube obstruction or tympanic adhesions for tympanoplasty combined with ventil ation tube insertion in otitis media in EENT Hospital of Fudan University from April 2008 to December 2010. Preoperative routine hearing tests and temporal bone CT examination. Completely remove of lesions at the same time and as much as possible to protect the integrity of the tympanic wall mucosa during operation. Reconstruction of the ossicular chain and simultaneous tympanic membrane hole and placed silicone T-type ventilation tube. All patients were tested for pure tone auditory threshold at 3 months after operation. The patients were followed up for 12 to 44 months.Result:The average hearing level of PTA (0.5,1.0,2.0 kHz) was (31.71±12.25) dBHL. 28 cases (80.0%) had improved to 40 dBHL after operation, 5 cases (14.3%) had hearing enhancement of 10-20 dBHL, and 2 patients (5.7%) had no change in hearing. The number of cases with air bone gap (ABG)(0.5, 1.0, 2.0 kHz) reduced to less than 20 dBHL was 25, 32 and 34 after operation. Ventilation tube self-prolapse in15 cases, 12 cases of artificial removal and 8 cases of inpatient. Twenty seven cases were left perforation of tympanic membrane, of which 22 cases (81.5%) were spontaneously healed and 5 cases(18.5%) were left with small perforations less than 2 mm in diameter. All of them had dry ear after operation, none of them had recurrence after operation, 33 cases (94.3%) had dry ear within 12 weeks, and only 2 cases(5.7%) had dry ear for more than 6 months.Conclusion: Tympanoplasty combined with ventilation tube insertion for the middle ear mucosal dysfunction and eustachian tube mucosal dysfunction of otitis media treatment effect is obvious. It does not extend the dry ear time and cause postoperative recurrence. This operation is feasible, reliable and effective.

Abstract
Objective:The intraoperative and postoperative clinical indexes of myringoplasty performed by endoscope or by microscope were collected retrospectively, the differences between the two different surgical methods were analysized. Method:Retrospective analysis of the clinical data of 70 cases (70 ears) udergoing myringoplasty in the department of Otolaryngology-Head and Neck Surgery, at the Second People's Hospital of Kashi from June 2014 to August 2015. According to the surgical approach cases were divided into two groups, 30 cases in group A by endoscopic myringoplasty and 40 cases in group B by microscope myringoplasty. The operation time, blood loss, postoperative dry ear time, wound healing scar hyperplasia, tympanic membrane perforation rate and hearing improvement rate were compared between the two groups, and SPSS 19.0 statistical software was used to analyze the differences between the two groups. Result:The operation time: Group A had an average of (35.23±6.38)min, less than group B (42.60±7.97)min, with statistical difference (P<0.05). The intraoperative blood loss: the average of group A was (7.33±2.11)ml, less than group B (17.93±3.84)ml, with statistical difference (P<0.05). The postoperative dry ear time more than 1 month: group A was 40%, lower than Group B (75%), with statistical difference (P<0.05). The postoperative incision healing scar hyperplasia: group A was 0%, lower than group B (5%), no significant difference (P>0.05). The tympanic membrane perforation rate: group A was 3.33%, lower than group B (7.5%), no significant difference (P>0.05). The postoperative hearing improvement rate: group A was 76.67%, lower than group B (80.00%), no significant difference (P>0.05). Conclusion:Compared with the traditional microscope surgery, endoscopic myringoplasty is a minimally invasive surgical technique which can get the same curative effect, but with a shorter operation time, less intraoperative blood loss, dry ear in shorter time , recovery more quickly, beautiful incision and other advantages. So it is worthy of clinical application.

Abstract
OBJECTIVE To investigate the preventive and therapeutic effects of rapamycin (RAPA) on autoimmune hepatitis and liver fibrosis induced by concanavalin A (ConA) and possible mechanisms. METHODS Female C57BL/6 mice aged 8 weeks were randomly divided into normal control group, ConA model group, and ConA+RAPA treatment group. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured; hematoxylin-eosin and Masson staining and Knodell HAI and Ishak scoring systems were used to evaluate the degrees of liver inflammation and fibrosis. Gradient centrifugation was used to separate mononuclear cells, flow cytometry was used to measure CD4(+)/CD8(+) ratio, and intracellular cytokine staining was performed to measure the levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-10 (IL-10), and transforming growth factor β (TGF-β) in immune cells. The t-test was used for data comparison between groups. RESULTS The RAPA treatment group showed a significant reduction in serum ALT level compared with the ConA model group (P < 0.05). Liver inflammatory injury was reduced significantly, and there was no obvious fibrous tissue proliferation. The level of TGF-β in mononuclear cells was reduced significantly, and the treatment group had a significantly lower level of TGF-β than the model group (8.91%±1.25% vs 16.65%±2.05%, P < 0.05). The proportions of CD4(+) and CD8(+)T cells in the liver were reduced, and the treatment group had significantly lower proportions of CD4(+) and CD8(+)T cells than the model group (proportion of CD4(+)T cells: 4.09%±1.20% vs 8.91%±0.69%, P < 0.05; proportion of CD8(+)T cells: 3.28%±0.66% vs 9.68%±1.46%, P < 0.05). The proportion of Th1 cells was reduced, and the treatment group had a significantly lower proportion of Th1 cells than the model group (1.02%±0.06% vs 2.83%±0.21%, P < 0.05); the proportions of Th3 and Tr1 regulatory T cells were increased, and the treatment group had significantly higher proportions of Th3 and Tr1 regulatory T cells than the model group (proportion of Th3 regulatory T cells: 59.53%±9.82% vs 47.13%±4.79%, P < 0.05; proportion of Tr1 regulatory T cells: 10.63%±2.27% vs 7.09%±1.66%, P < 0.05), but the proportion of Th2 cells showed no significant difference between the two groups (P > 0.05). CONCLUSION RAPA can promote the differentiation of Th3/Tr1 cells, reduce the expression of TGF-β in mononuclear cells, slow down the progression of chronic hepatitis induced by ConA into liver fibrosis, and thus prevent liver fibrosis.

Abstract
This current cross-sectional study investigates the relationship between thyroid hormones and peripheral artery disease (PAD) among euthyroid Chinese population aged 40 years and above. Serum free triiodothyronine (FT3), free thyroxin (FT4), thyroid-stimulating hormone (TSH), and thyroid antibodies were measured. PAD was defined as ankle-brachial index (ABI) < 0.9. There were 91 (2.9%) PAD cases among the 3,148 euthyroid study participants. Participants in the highest quartile of FT3 and free-triiodothyronine-to-free-thyroxin (FT3/FT4 ratio) had a decreased risk of prevalent PAD (multivariate-adjusted odds ratio, 95% confidence interval: 0.32, 0.15-0.62, P for trend = 0.01 and 0.31, 0.13-0.66, P for trend = 0.004, respectively) compared to those in the lowest quartile. To conclude, FT3 levels and the FT3/FT4 ratio was inversely associated with prevalent PAD in euthyroid Chinese population aged 40 years and above.

Abstract
OBJECTIVE To update the estimated prevalence rates of smoking and examine major metabolic diseases associated with smoking status in Chinese adults. METHODS Using a complex, multistage, probability sampling design, we recruited a nationally representative sample of 98,658 Chinese adults aged ⋝18 years in 2010. Information on current, former, never, and passive smoking status was obtained using a standard questionnaire. All estimates were weighted to represent the overall Chinese adult population. RESULTS The estimated proportion of current smokers was 28.3% for Chinese adults aged ⋝18 years. The corresponding values of former and passive smokers were 5.1% and 21.4%, respectively. Additionally, former smokers were found to have a less favorable metabolic risk profile among all categories of smoking status in both men and women. The prevalence of metabolic diseases such as diabetes and hypertension also increased with a greater number of smoking pack-years in men. CONCLUSION The prevalences of current smoking and passive smoking remain high in Chinese adults.

Abstract
The development of transverse instability in the radiation-pressure-acceleration dominant laser-foil interaction is numerically examined by two-dimensional particle-in-cell simulations. When a plane laser impinges on a foil with modulated surface, the transverse instability is incited, and periodic perturbations of the proton density develop. The growth rate of the transverse instability is numerically diagnosed. It is found that the linear growth of the transverse instability lasts only a few laser periods, then the instability gets saturated. In order to optimize the modulation wavelength of the target, a method of information entropy is put forward to describe the chaos degree of the transverse instability. With appropriate modulation, the transverse instability shows a low chaos degree, and a quasi-monoenergetic proton beam is produced.

Abstract
OBJECTIVE The aim of this study was to assess the levels of serum lipid and awareness, treatment, and control of dyslipidemia in type 2 diabetes mellitus (T2DM) patients from top-ranked endocrinology clinics in large cities of China. MATERIALS AND METHODS A cross-sectional study in a representative sample of 4807 Chinese adults 40 to 75 years of age was conducted during 2010 to 2011 at 20 endocrinology clinics in top-ranked hospitals covering most of the major cities of China. Serum lipid levels were measured, and treatment of dyslipidemia was recorded and assessed. RESULTS In the present study, the prevalence of dyslipidemia was 67.1% in T2DM subjects. Among those with dyslipidemia, the proportion of awareness and treatment was 68.7% and 55.9%. Among participants with lipid-lowering therapy, 686 subjects achieved the low-density lipoprotein cholesterol (LDL-C) control less than 2.60 mmol/L, with the rate being 39.4%. In those patients with previous cardiovascular disease, the percentage of participants who achieved LDL-C goal (1.80 mmol/L) was 15.3%. CONCLUSION The prevalence of dyslipidemia is high, and the awareness, treatment, and control of dyslipidemia are relatively low in Chinese T2DM patients. This calls for the awareness and intervention of dyslipidemia in these patients.

Abstract
BACKGROUND The role that probiotics play in relieving irritable bowel syndrome (IBS) has been demonstrated; however, the mechanism by which IBS is affected remains unclear. In this study, serotonin transporter (SERT) mRNA and serotonin transporter protein (SERT-P) levels in HT-29, Caco-2 cells, and mice intestinal tissues were examined after treatment with Lactobacillus rhamnosus GG supernatant (LGG-s). METHODS HT-29 and Caco-2 cells were treated with different concentrations of LGG-s for 12 and 24 h and C57BL/6 mice received supplements of different concentrations for 4 weeks. SERT mRNA and SERT-P levels were detected by real-time PCR and Western blotting. KEY RESULTS SERT mRNA and SERT-P levels in HT-29 and Caco-2 cells were higher than those in the control 24 h after treatment. Undiluted LGG-s upregulated SERT mRNA levels by 9.4-fold in the first week, which dropped in the second week. The double-diluted LGG-s upregulated SERT mRNA by 2.07-fold in the first week; levels dropped to 1.75-fold within the second week and under base expression levels by the third week, while they again climbed to 1.56-fold in the fourth week. The triple-diluted LGG-s could not upregulate SERT mRNA expression until the end of the fourth week. The SERT-P levels in the double-diluted LGG-s group were higher than that in the control but fluctuated with time. SERT-P levels in the triple-diluted LGG-s were higher than that in the control in the last 2 weeks and increased with time. CONCLUSIONS & INFERENCES LGG-s can upregulate SERT mRNA and SERT-P levels in intestinal epithelial cells and mice intestinal tissues.

Abstract
Ampelopsis grossedentata, an indigenous plant in southern China, has been used for treating pharyngitis in traditional Chinese medicine for hundreds of years. In this study, we explored the anti-inflammatory activity of dihydromyricetin (1), its major bioactive component, and the underlying mechanism of this action. We demonstrated that 1 suppressed the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) as well as increased the level of the anti-inflammatory cytokine interleukin-10 (IL-10) in lipopolysaccharide (LPS)-treated mice. Moreover, 1 was found to markedly inhibit the production of nitric oxide (NO) and the levels of TNF-α, IL-1β, and IL-6, whereas it increased the level of IL-10 in LPS-induced RAW 264.7 macrophage cells. Compound 1 also reduced the protein expression of inducible nitric oxide synthase (iNOS), TNF-α, and cyclooxygenase-2 (COX-2) in macrophage cells. Furthermore, 1 suppressed the phosphorylation of NF-kappa B (NF-κB) and IκBα as well as the phosphorylation of p38 and JNK but not ERK1/2 in LPS-stimulated macrophages. Taken together, the present results suggest that 1 exerts its topical anti-inflammatory action through suppressing the activation of NF-κB and the phosphorylation of p38 and JNK. Thus, 1 may be a potentially useful therapeutic agent for inflammatory-related diseases.

Abstract
AIM To examine the association between depression and impaired glucose regulation, newly diagnosed diabetes and previously diagnosed diabetes in middle-aged and elderly Chinese people, and whether depression was associated with different treatment regimens or durations of diabetes. METHODS A cross-sectional study was performed among 229,047 adults living in the community aged ≥ 40 years from 25 centres in China. The self-reported depression rating scale Patient Health Questionnaire 9 (PHQ-9) was used to diagnose probable and sub-threshold depression. Glucose metabolism status was determined according to World Health Organization 1999 diagnostic criteria. RESULTS The numbers of participants with normal glucose regulation, impaired glucose regulation, newly diagnosed diabetes and previously diagnosed diabetes were 120,458, 59,512, 24,826 and 24,251, respectively. The prevalence of sub-threshold depression in the total sample of participants was 4.8% (4.8%, 4.8%, 4.4% and 5.6% from normal glucose regulation to previously diagnosed diabetes, respectively), and the prevalence of probable depression was 1.1% (1.1%, 1.0%, 0.9% and 1.8% from normal glucose regulation to previously diagnosed diabetes, respectively). Compared with participants with normal glucose regulation, those with previously diagnosed diabetes had increased odds of probable depression [odds ratio (OR) = 1.61, 95% confidence interval (CI) 1.39-1.87] and sub-threshold depression (OR = 1.14, 95% CI 1.06-1.24), after adjustment for multiple confounding factors. Newly diagnosed diabetes or impaired glucose regulation was not associated with depression. Among those with previously diagnosed diabetes, insulin treatment was associated with greater odds of depression compared with no treatment or oral anti-diabetic medicine. CONCLUSION Previously diagnosed diabetes, but not newly diagnosed diabetes or impaired glucose regulation, was associated with a higher prevalence of depression. Patients receiving insulin were more likely to have depression than those not receiving treatment or being treated with oral anti-diabetic medicine.

Abstract
PURPOSE We investigated correlations of somatic BRAF V600E mutation and RET/PTC1 rearrangement with recurrent disease in Chinese patients with papillary thyroid carcinoma (ptc). METHODS This prospective study included 214 patients with ptc histologically confirmed between November 2009 and May 2011 at a single institute. RESULTS We found somatic BRAF V600E mutation in 68.7% and RET/PTC1 rearrangement in 25.7% of the patients. Although BRAF mutation was not significantly associated with clinicopathologic features such as patient sex or age, multicentric disease, thyroid capsule invasion, tumour stage, or nodal metastasis, it was significantly associated with recurrent disease. Multivariate analysis revealed that BRAF mutation and tumour size were independent risk factors associated with recurrent disease, with odds ratios of 9.072 and 2.387 respectively. The area under the receiver operating characteristic curve increased 8.3% when BRAF mutation was added to the traditional prognostic factors, but that effect was statistically nonsignificant (0.663 vs. 0.746, p = 0.124). RET/PTC1 rearrangement and nodal metastasis were significantly associated in all patients (p = 0.042), marginally associated in ptc patients (p = 0.051), but not associated in microptc patients (p = 0.700). RET/PTC1 rearrangement was not significantly associated with recurrent disease. CONCLUSIONS BRAF positivity is an independent predictor of recurrent disease in ptc.

Abstract
OBJECTIVE To study the relation between serum calcium level and elevated BaPWV in Chinese subjects. METHODS The relation between serum calcium level and elevated BaPWV was studied in 9 615 subjects. The mean value of left and right BaPWV was analyzed. BaPWV was defined as high when it was ⋝1752.5 cm/s (the upper quartile) either side. RESULTS The BaPWV and its elevated percentage progressively increased across the quartiles of the serum calcium level (P<0.05). The prevalence of elevated BaPWV was significantly higher in subjects of the second, third and highest quartiles than in those of the lowest quartile (26.9%, 28.4%, and 33.2% vs 23.7%, P=0.0116, P=0.0004, and P<0.0001). Logistic regression analysis revealed that the risk of elevated BaPWV was 1.32- fold higher in subjects of the highest quartile than in those of the lowest quartile (OR=1.32, 95% CI: 1.08-1.60). CONCLUSION The elevated serum calcium level is related to an elevated BaPWV and a higher risk of arterial stiffness, independent of conventional risk factors, in middle-aged and elderly Chinese subjects.

Abstract
A total of 1116 middle-aged and elderly men and 1442 postmenopausal women were recruited in this study. Whether bisphenol A exposure was associated with circulating sex hormone concentrations was studied. Univariate analysis revealed that the urinary bisphenol A concentration was negatively correlated with the serum levels of luteinizing hormone (β=-0.061, P<0.0001) and follicle-stimulating hormone (β=-0.086, P<0.0001) in men, and with the serum levels of follicle-stimulating hormone (β=-0.037, P=0.018) and sex hormone-binding globulin (β=-0.043, P=0.006) in women. However, no significant association was observed between the serum levels of urinary bisphenol A and circulating sex hormone after adjustment for the potential confounders.

Abstract
OBJECTIVE To study the relationship between resting heart rate and blood lipid level. METHODS A total of 9 415 subjects aged ⋝ 40 years were included in the present study. Their resting heart rate was monitored and their serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were measured to define dyslipidemia according to the 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. RESULTS The subjects were divided into group A with their resting heart rate <70 beats/min, group B with their resting heart rate =70-79 beats/min, group C with their resting heart rate =80-89 beats/min, and group D with their resting heart rate ⋝ 90 beats/min. High TG, TC, and LDL-C were presented across the resting heart rate (Ptrend <0.01). Multiple logistic regression analysis revealed that the risk of high TG and TC was higher in subjects with their resting heart rate ⋝ 90 beats/min than in those with their resting heart rate <70 beats/min (OR=1.42; 95% CI: 1.16-1.74 and OR=1.33; 95% CI: 1.09-1.64, respectively). CONCLUSION Elevated resting heart rate is associated with high TG and TC in middle-aged and elderly Chinese subjects.

Abstract
Sequence-related amplified polymorphism (SRAP) is a new molecular marker technology developed based on polymerase chain reaction. The authenticity of 84 progenies of 8 hybrid combinations of Stylosanthes guianensis was identified by SRAP markers to select the true hybrids used in the present study. A total of 35 SRAP primer combinations were selected from the parents of 8 hybrid combinations. The selected polymorphism primer combinations were applied to identify the authenticity of all progenies. The male parents of the primer combinations had specific markers, whereas the female parents did not. 68 progenies exhibited male parent-specific bands, which were identified as true hybrids. The rest of the progenies were considered self-hybrids because of the absence of male parent-specific bands. The results of hybrid identification provided solid evidence for further studies of hybrids and demonstrated SRAP molecular markers as a useful technology for assessing the purity of S. guianensis hybrids.

Abstract
OBJECTIVE To study the optimal waist circumference (WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. METHODS A total of 2,873 men and 5,559 women were included in this cross-sectional study. Metabolic syndrome (MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. RESULTS The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. CONCLUSION The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.

Abstract
Blumea balsamifera is a commercially important medicinal herb in China and other parts of Asia. It is used to produce borneol. This plant grows in the wild, but resources have diminished greatly in recent years. We examined the genetic diversity of this species to help develop conservation strategies; 35 plants from five provinces were analyzed using AFLPs. Eight AFLP primer combinations generated 1367 fragments, giving a mean of 172 fragments per primer combination. Polymorphism in the germplasm analysis was found for 1360 (99.48%) of the fragments, of which 264 (19.27%) fragments were unique (accession specific) and 423 (25.33%) of the fragments were rare (present in less than 10% of the accessions). The polymorphic fragments were used to group the accessions in a UPGMA phenogram. Most grouping was geographical. In general, accessions coming from Guizhou and Guangxi showed higher diversities as these accessions were scattered in different groups. The genetic distance estimated by Jaccard similarity coefficient index showed low variability among genotypes (coefficient value ranged from 0.60 to 0.95). More attention should be given to the study and conservation of the biodiversity of this economically important genus.

Abstract
Pseudoperonospora cubensis is a foliar pathogen of cucurbits. In cucumber, it produces chlorotic, angular lesions with dark sporangia on their under-surface. The distribution of pathotypes and mating types of P. cubensis were investigated in seven provinces in China. Twenty-nine isolates were obtained from Guangdong, Anhui, Hubei, Sichuan, Shandong, Beijing, and Harbin, one to six isolates from each province. They were collected from cucumber during summer 2011, except those from Harbin, which were collected from cucumber in summer 2012. Isolates were tested for pathogenicity and mating type. Pathogenicity was tested by inoculation of detached leaves of: cucumber (Cucumis sativum cvs. Bet-Alpha, SMR18), melon (Cucumis melo reticulatus cv. Ananas-Yokneam), pumpkin (Cucurbita maxima cv. Tripoli), squash (Cucurbita pepo, cv. Beruti), butternut gourd (Cucurbita moschata cv. Waltham), watermelon (Citrullus lanatus, cv. Malali), and sponge gourd (Luffa cylindrica, cultivar unknown). Mating type was determined by oospore production in melon leaf discs inoculated with mixed sporangia of a test isolate and A1 or A2 tester isolates, as recently described (2). The results showed that 22 isolates belonged to pathotype 3, sporulating on cucumber and melon; five isolates belonged to pathotype 6, sporulating on cucumber, melon, pumpkin, squash, and butternut gourd; one isolate belonged to pathotype 5, sporulating on the above five species and watermelon (1), and one isolate was capable of sporulating on the mentioned five species and sponge gourd, herein called pathotype 7. Of the 29 isolates tested, 22 belonged to the A1 mating type, six to the A2 mating type, and one did not produce oospores with either testers. Of the six A2 isolates, two originated from Sichuan, one from Beijing, and three from Harbin. All 22 isolates belonging to pathotype 3 were A1, whereas the other six isolates (four pathotype 6, one pathotype 5, and one pathotype 7) were A2. Crosses made between Chinese isolates belonging to opposite mating types resulted in the formation of abundant oospores in detached melon or cucumber leaves. The results prove that the A2 mating type of P. cubensis occurs in China. This explains the abundant occurrence of oospores of P. cubensis in nature in China (4). The data corroborate with Runge et al. (3), who suggested that the recent changes in the population structure of P. cubensis around the world resulted from the migration of a new genotype of P. cubensis from the Far East to Europe and the U.S.A. In Israel, a new pathotype attacking both Cucumis and Cucurbita appeared in 2002 (1), and A2 mating type first appeared in 2010 (2). References: (1) Y. Cohen et al. Phytoparasitica 31:458, 2003.

Abstract
The Fukuda stepping test (FST) is widely used in neurology and for the diagnosis of vertigo-associated disease, but its reliability is disputed. This study assessed the accuracy of the FST in determining the side of vestibular dysfunction in 126 patients with unilateral vestibular lesion. Abnormal deviation towards the side of the lesion occurred in 50.0% of cases and towards the intact side in 24.6% of cases, with 25.4% of patients within the normal range (< 45° deviation). An equal percentage of patients with acute stage vertigo (0-3 days after onset) deviated towards the intact and lesion sides, however the percentage of patients deviating to the intact side decreased over time. A subset of patients who originally deviated towards the intact side gradually began to deviate towards the lesion side. Care should be taken when using the FST to determine the side of the lesion, particularly in acute stage vertigo.

Abstract
Two-year-old seedlings of licorice plant (Glycyrrhiza uralensis Fisch) were exposed to three degrees of water deficit, namely weak (60-70%), moderate (40-50%), and strong (20-30%) relative water content in soil, whereas control plants were grown in soil with 80-90% water content. Moderate and strong water deficit decreased the net photosynthetic rate, stomatal conductance, and biomass production. Water use efficiency and the root-to-shoot ratio increased significantly in response to water deficit, indicating a high tolerance to drought. Weak water deficit did not decrease root biomass production, but significantly increased the production of glycyrrhizic acid (by 89%) and liquiritin (by 125%) in the roots. Therefore, a weak water deficit can increase the yield of root medical compounds without negative effect on root growth.

Abstract
To evaluate whether parvovirus B19, a common human pathogen, was also involved in papillary thyroid carcinoma (PTC), 112 paraffin-embedded thyroid specimens of benign nodules, papillary, medullary and follicular carcinomas, and normal controls were examined for B19 DNA and capsid protein by nested PCR, in situ hybridisation (ISH) and immunohistochemistry (IHC). The expression of the nuclear factor-κB (NF-κB) was investigated by IHC. The results showed B19 DNA commonly exists in human thyroid tissues; however, there were significant differences between PTC group and normal controls, and between PTC and nonneoplastic adjacent tissues (P<0.001). The presence of viral DNA in PTC neoplastic epithelium was confirmed by laser-capture microdissection and sequencing of nested PCR products. B19 capsid protein in PTC group was significantly higher than that of all the control groups and nonneoplastic adjacent tissues (P⩽0.001). Compared with control groups, the activation of NF-κB in PTC group was significantly increased (P⩽0.02), except for medullary carcinomas, and the activation of NF-κB was correlated with the viral protein presence (P=0.002). Moreover, NF-κB was colocalised with B19 DNA in the neoplastic epithelium of PTC by double staining of IHC and ISH. These results indicate for the first time a possible role of B19 in pathogenesis of PTC.
