ABSTRACT

To determine the content of extracts in different processed products of Chuanxiong Rhizoma and the content of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A and ligustilide, in order to study the effect of different proces-sing methods on the alcohol-soluble extract and the content of six ingredients of Chuanxiong Rhizoma. The extract was determined according to the alcohol-soluble extract determination method set forth in item 2201 of the 2020 Chinese Pharmacopoeia Ⅳ; the content was determined by using Agilent TC-C_(18) column(4.6 mm×250 mm, 5 μm) for gradient elution, with acetonitrile(A)-0.5% acetic acid solution(B) as the mobile phase; the column temperature was at 30 ℃; the flow rate was 1.0 mL·min~(-1), the detection wavelength was 285 nm; and the injection volume was 10 μL. Compared with Chuanxiong Rhizoma, the extracts of processed products all increased significantly; by the degree of increase, the order was stir-frying Chuanxiong Rhizoma with honey>stir-frying Chuanxiong Rhizoma with rice wine>stir-frying Chuanxiong Rhizoma with Angelicae Dahuricae Radix decoction>stir-frying Chuanxiong Rhizoma with tea decoction; the HPLC method was convenient and reliable, with a high linear relationship of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A and ligustilide, and a high precision, repeatability, stability and the sample recovery rate in Chuanxiong Rhizoma and its processed products. There were 15 chromatographic peaks before and after processing, eight of them were identified. Compared with the pre-processing, two chromatographic peaks were added after the stir-frying with honey and rice wine; and four chromatographic peaks were added after the processing with Angelicae Dahuricae Radix decoction; the contents of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A, and ligustilide in stir-frying Chuanxiong Rhizoma with rice wine were all reduced. Except for the content of ferulic acid that increased, the content of the other five components decreased in stir-frying Chuanxiong Rhizoma with honey, stir-frying Chuanxiong Rhizoma with tea decoction, and stir-frying Chuanxiong Rhizoma with Angelicae Dahuricae Radix decoction. Rice wine, honey, decoction of tea and Angelicae Dahuricae Radix could all promote the dissolution of chemical components in Chuanxiong Rhizoma, and increase the content of extract; the changes in the contents of six components of different processed products could provide a certain basis for studying chemical composition and efficacy of different processed products of Chuanxiong Rhizoma.

ABSTRACT

OBJECTIVE@#To investigate whether Ershen Pill (ESP, ) could alleviate the symptom of Pi (Spleen)-Shen (Kidney) yang deficiency (PSYD)-induced diarrhea in rat model and explore its anti-diarrhea mechanism.@*METHODS@#Seventy-five Sprague-Dawley rats were divided into 5 groups by a random number table, including control, positive, model, low-dose (LD) and high-dose (HD) ESP groups, 15 rats in each group. All the rats, except those in the control group, were developed PSYD induced-diarrhea based on its pathology and etiology. The rats in positive, LD and HD ESP groups were treated with Shenling Baizhu Pill (), LD (1.05 g/kg) or HD (3.50 g/kg) ESP petroleum ether extract once a day for 2 weeks, respectively. Body weight change and diarrhea index were measured. The histology scores of the kidney were evaluated via hematoxylin and eosin (HE) staining. Aquaporin-3 (AQP3) expression in the colon was analyzed by immunofluorescence, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot, respectively.@*RESULTS@#Compared with the model group, oral administration of LD and HD ESP prevented body weight loss and inhibited diarrhea after 2-week treatment (P<0.05). Kidney deterioration was impeded, and the histology score in LD and HD ESP groups were 8.2 and 10.5, respectively, which were both higher than those in the model group (P<0.05). In addition, ESP treatment alleviated rat colitis, and HD ESP significantly improved the AQP3 positive staining intensity in the colon tissue compared with the model group. The result from Western blot revealed that AQP3 protein synthesis in colon tissue of LD and HD ESP groups increased by 2.1- and 5.9-fold compared with the model group (P<0.05). qRT-PCR result showed that AQP3 gene expression in the HD ESP group was also up-regulated by 2.5-fold normalized to the model group (P<0.05).@*CONCLUSION@#ESP extract effectively alleviates the symptoms of PSYD and relieves PSYD-induced diarrhea by improving AQP3 synthesis in the colon.

ABSTRACT

As one of the three pillars of Chinese medicine industry, traditional Chinese medicines prepared in ready-to-use forms are important raw materials for clinical medication and production of Chinese patent drugs. By considering the literature of Curcumae Radix, a multi-source Chinese herb and the situation of market investigation, the modern evaluation method based on traditional grading was introduced for comprehensive evaluation of the processed Curcumae Radix. The correlation between traditional grading method and modern evaluation index was explored to establish the grading standard of Curcumae Radix. According to the comprehensive evaluation, Curcumae Radix was divided into four grades: superior, first, second and third grades under the guidance of the theory of traditional Chinese medicine. This study provides a new idea for the grading of multi-source processed Chinese medicine, achieving high quality and good price, which is helpful to improve the clinical efficacy.

ABSTRACT

The metabonomics method was used to study the intervention effect of Psoraleae Fructus and Myristicae Semen in "Ershen pill" on the changes in serum endogenous metabolites in spleen-kidney Yang deficiency diarrhea rats before and after processing, screen out differentiated metabolites related to spleen-kidney Yang deficiency diarrhea and explore the metabolic patterns related to spleen-kidney Yang deficiency diarrhea and the processing synergy mechanism of Psoraleae Fructus and Myristicae Semen in "Ershen pill". Efforts were made to detect SOD and MDA of each group, test rat serum metabolic fingerprints in different stages by using GC-MS, analyze by PCA and PLS-DA methods and screen out potential biomarks through VIP and t test. The results revealed that "Ershen pill" could enhance the level of SOD and decrease the level of MDA and identified 10 differentiated metabolites related to spleen-kidney Yang deficiency diarrhea. Compared with the model group, all of metabolites recovered to varying levels after being intervened with "Ershen pill", with the best effect shown in the "Ershen pill" IV group (salt-processed Psoraleae Fructus + bran-roasted Myristicae Semen). It is speculated that that Psoraleae Fructus and Semen Myristicae in "Ershen pill" show a synergistic effect by inhibiting peroxide, improving aglucolipid, amino acids and energy metabolism, with multiple target sites.

ABSTRACT

<p><b>BACKGROUND</b>Our previous study has confirmed that one bout of exhaustion (Ex) can cause hippocampus neurocyte damage, excessive apoptosis, and dysfunction. Its initial reason is intracellular calcium overload in hippocampus triggered by N-methyl-D-aspartic acid receptor (NMDAR) over-activation. NMDAR activation can be suppressed by γ-aminobutyric acid (A) receptor (GABAAR). Whether GABAAR can prevent intense exercise-induced hippocampus apoptosis, damage, or dysfunction will be studied in this study.</p><p><b>METHODS</b>According to dose test, rats were randomly divided into control (Con), Ex, muscimol (MUS, 0.1 mg/kg) and bicuculline (BIC, 0.5 mg/kg) groups, then all rats underwent once swimming Ex except ones in Con group only underwent training. Intracellular free calcium concentration ([Ca2+]i) was measured by Fura-2-acetoxymethyl ester; glial librillary acidic protein (GFAP) and synaptophysin (SYP) immunofluorescence were also performed; apoptosis were displayed by dUTP nick end labeling (TUNEL) stain; endoplasmic reticulum stress-induced apoptosis pathway was detected by Western blotting analysis; Morris water maze was used to detect learning ability and spatial memory.</p><p><b>RESULTS</b>The appropriate dose was 0.1 mg/kg for MUS and 0.5 mg/kg for BIC. Ex group showed significantly increased [Ca2+]i and astrogliosis; TUNEL positive cells and levels of GFAP, B cell lymphoma-2 (Bcl-2) associated X protein (Bax), caspase-3, caspase-12 cleavage, CCAAT/enhancer binding protein homologous protein (CHOP), and p-Jun amino-terminal kinase (p-JNK) in Ex group also raised significantly compared to Con group, while SYP, synapse plasticity, and Bcl-2 levels in Ex group were significantly lower than those in Con group. These indexes were back to normal in MUS group. BIC group had the highest levels of [Ca2+]i, astrogliosis, TUNEL positive cell, GFAP, Bax, caspase-3, caspase-12 cleavage, CHOP, and p-JNK, it also gained the lowest SYP, synapse plasticity, and Bcl-2 levels among all groups. Water maze test showed that Ex group had longer escape latency (EL) and less quadrant dwell time than Con group; all indexes between MUS and Con groups had no significant differences; BIC had the longest EL and least quadrant dwell time among all groups.</p><p><b>CONCLUSIONS</b>Activation of GABAA R could prevent intense exercise-induced synapses damage, excessive apoptosis, and dysfunction of hippocampus.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Mycoplasma pneumoniae (MP) is an important pathogen for community-acquired pneumonia in children. MP infection was considered to be self-limited, but many severe refractory MP pneumonia cases have been reported in recent years. The reason for variation in severity of MP pneumonia remains unclear. MP virulence including drug-resistance and host immunologic function are important influencing factors. The present study aimed to clarify relationship between local MP load and severity of MP pneumonia.</p><p><b>METHOD</b>MP DNA was quantitatively detected by fluorescent real-time PCR in bronchoalveolar lavage fluid (BALF) from 77 children with MP pneumonia. They were classified into groups of low MP load ( < 10(3)/ml, n = 14) , moderate MP load (10(3)-10(6)/ml, n = 22) and high MP load ( > 10(6)/ml, n = 41) . Clinical symptoms, main laboratory and imaging results of children among the three groups were compared.</p><p><b>RESULT</b>When compared with low load group and moderate load group, high load group had longer fever duration (7 d, 10 d vs. 12 d) , longer time to normalization of temperature with macrolide administration (4 d, 8 d vs. 10 d) , more patients with high fever (50.0%, 68.2% vs. 87.8%) and longer duration of fever than 10 d (35.7%, 50.0% vs. 73.2%).Statistically significant difference existed in CRP among the three groups (1.0 mg/L, 11.5 mg/L, 34 mg/L). Large field of consolidation or atelectasis were found in 58.5% of high load patients, much higher than 22.7% in moderate load and 14.3% in low load patients. Bilateral or massive pleural effusion was not found in low load group, while in moderate load and high load group, they were 13.6% and 24.4%. However, no significant difference was found in symptoms and main laboratory and imaging results among different age groups in high load patients.</p><p><b>CONCLUSION</b>There is a close relationship between MP load in BALF and clinical characteristics in children with MP pneumonia. Those with high MP load have a more severe process.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the incidence and clinical features of mixed infections in children with Mycoplasma pneumoniae (MP) pneumonia.</p><p><b>METHOD</b>A total of 201 cases diagnosed as MP pneumonia were investigated for mixed infections by sputum bacterial culture, respiratory virus antigen detection and serum Chlamydia pneumoniae antibody test. For those with the indications for bronchoscopy, we also did bronchoalveolar lavage and lavage bacterial culture.</p><p><b>RESULT</b>A high incidence (103/201, 51.2%) of mixed infections in children with MP pneumonia was revealed. The most frequent co-infected pathogen was Chlamydia pneumoniae (52, 25.9%), followed by viruses (29, 14.4%), and bacteria (22, 10.9%). Among viruses, respiratory syncytial virus was the most common (17, 8.5%), followed by adenovirus (6, 3.0%), parainfluenza virus type III (4, 2.0%) and influenza virus type B (2, 1.0%). Sputum bacterial culture was positive in 14/201 (7.0%) cases, Streptococcus pneumonia being most common (6, 3.0%). BALF culture yielded positive results in 11.6% (8/69), Streptococcus pneumonia was also common (5, 7.3%). Among 29 cases with MP and virus coinfection, 26 were younger than 3 years (89.7%), while for MP and Chlamydia pneumoniae coinfection, most of them were older than 3 years (40/52, 76.9%). Compared with non-mixed infections, those with mixed infections had longer fever duration (24.5% and 40.8% longer than 10 d), more frequently developed pleural effusion (11.2%, 23.3%) and large area of shadow in chest imaging (35.7%, 51.5%). White blood cell [(14.28 ± 4.99) × 10(9)/L], C-reactive protein (CRP) [69(32.5 - 99.5) mg/L] and neutrophil ratio in BALF [0.86 (0.63 - 0.91)] were much higher in children with mixed bacterial infections than that in non-mixed infections [(9.06 ± 3.47) × 10(9)/L, 3 (0 - 31.0) mg/L, 0.44 (0.03 - 0.88)]. But no significant difference was found in peripheral blood neutrophil proportion between mixed bacterial infections (0.38 ± 0.25) and non-mixed infections (0.51 ± 0.19).</p><p><b>CONCLUSION</b>More than half of cases with MP pneumonia had mixed infections, most commonly caused by Chlamydia pneumonia followed by viruses. The incidence of mixed infections with bacteria was low. Mixed infections with virus were more common in young children, while mixed infection with Chlamydia pneumoniae was more common in older ones. Bacterial infections should be paid more attention, especially those caused by Streptococcus pneumoniae, for those with high peripheral white blood cell counts, high CRP levels and high proportion of neutrophils in BALF.</p>

ABSTRACT

To analyze the clinical and radiological features of paragonimiasis in children and raise the awareness of this disease. A total of 58 paragonimiasis patients were reviewed. They were 42 boys and 16 girls aged 2.0 to 15.3 years. Among these patients, 20 were diagnosed in the recent 5 years, 46 with a history of raw water or food ingestion. Except 2 patients without any complaint, the most common features involved the systemic [41, 70.7%] and respiratory systems [43, 74.1%], followed by abdominal, cardiac and nervous systems, with rash and mass. Eosinophilia was noted in 46 [79.3%] patients, granulocytosis in 45 [77.6%], anemia in 14 [24.1%], and thrombocytopenia in 3. Imageology showed pneumonia in 26 [44.8%] patients, pleurisy in 28 [48.3%], hydropericardium in 17 [29.3%], ascites in 16 [27.6%], and celiac lymphadenitis in 13 [22.4%]. Besides hepatomegaly and splenomegaly, calcification and multiple lamellar low echogenic areas in the liver were noted, each in one patient. Abnormal brain imaging was noted in 4 of 10 patients. Karyocyte hyperplasia with eosinophilia was noted in all the 19 patients who received bone marrow puncture. Paragonimiasis should be considered in the differential diagnosis of patients with multiple organs or system lesions, especially those with eosinophilia, serous cavity effusion, respiratory, cardiac, digestive system, nervous system abnormality, and/or mass. Healthy eating habit is helpful for paragonimiasis prevention

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical features of systemic lupus erythematosus (SLE) with pulmonary pleural lesion in children.</p><p><b>METHODS</b>One hundred and thirty three child patients with SLE admitted from 2001 to 2010 were enrolled in the study. The clinical data, chest X-ray findings and laboratory examination were retrospectively reviewed. Cases with infectious pulmonary pleural lesion were excluded.</p><p><b>RESULTS</b>According to chest X-ray findings pleural pulmonary lesions were involved in 45 out of 133 cases with SLE (33.83 %); however, only 30 cases (66.67 %) had positive respiratory manifestations. Respiratory features included cough and/or sputum (55.56 %), dyspnea and chest pain (15.56 % and 11.11 %), and only 28.89 % case with pleural pulmonary lesions had rales. Chest X-ray findings included pleural effusion/pleurisy (32 cases, 71.11%), bronchial pneumonia (21 cases, 46.67%) or interstitial pulmonary disease (13 cases, 28.89%). Compared to children without pulmonary pleural lesion, children with pulmonary pleural lesion had higher incidence of leukopenia, lower C₃ or antibody dsDNA (+) (all P<0.05). There was no difference in abnormality of erythrocyte sedimentation rate (ESR), CRP, IgG,IgA,IgM, thrombocytopenia, antibody ANA(+), anti-SSA(+), anti-SSB(+) or anti-Sm(+) between children with or without pulmonary pleural lesion (P>0.05).</p><p><b>CONCLUSION</b>High incidence of pulmonary pleura lesions are present in children with SLE, however, clinical manifestations are lack of specificity or even no respiratory manifestation. Chest X-ray or HRCT scan are necessary in all cases with SLE. Children with leukopenia, lower C₃ or antibody dsDNA (+) are more likely to have pulmonary pleural lesion.</p>

ABSTRACT

<p><b>BACKGROUND</b>Invasive cancer of the cervix is considered a preventable disease because it has a long pre-invasive state, cervical cytology screening programs are currently available, and treatment of pre-invasive lesions is effective. We tested the accuracy of frozen section examination (FSE) of cone specimens to identify the endocervical margin and rule out invasion in patients with high-grade cervical intraepithelial neoplasia (CIN).</p><p><b>METHODS</b>For 320 consecutive patients with a preoperative biopsy result of CIN stage 2/3, cold-knife conization (CKC) was performed followed by FSE. The results from analyses of permanent paraffin sections (PS) were compared with the FSE findings.</p><p><b>RESULTS</b>The accuracy of FSE was 87% (278/320). For all of the seven patients with an invasive squamous cell carcinoma of the cervix identified by FSE, the diagnosis was confirmed by PS analysis. For one patient, the FSE result was cervicitis, whereas PS analysis showed microinvasive carcinoma. Appropriate surgery was performed for all patients based on the FSE and biopsy results. The FSE and PS results were not significantly different (P = 0.000). Definitive examination of margin status using PS was concordant with FSE findings in all cases.</p><p><b>CONCLUSIONS</b>FSE is a rapid and reliable method for evaluating CKC specimens. It can identify frank invasion, permit adequate treatment in a one-stage procedure, and reliably detect clear resection margins. Since discrepancies do exist and may result in inappropriate treatment, further research is required to decrease these discrepancies and avoid missing even one case.</p>

ABSTRACT

<p><b>OBJECTIVE</b>The P1 protein of Mycoplasma pneumoniae (MP) plays an important role in the pathogenesis of MP pneumonia. It mediates the attachment of the pathogen to host cells and elicits a strong humoral immune response during infection. In early studies, only two types of MP P1 genes were assumed to exist. Later, eight subtypes of MP P1 genes and some variations of P1 gene were reported. However, there are no related reports in China until now. This study aimed to understand epidemiology of MP subtype in Zhejiang province, China, as well as the relationship between MP subtype and clinical severity of MP pneumonia.</p><p><b>METHOD</b>Clinical samples were collected by nasopharyngeal aspiration from children with MP pneumonia hospitalized in the Children's Hospital of Zhejiang University School of Medicine from February to December in 2009. P1 gene fragment was amplified by using PCR method (with primers of ADH1/ADH2 and ADH3/ADH4, respectively). Then ADH1/ADH2-generated fragments were digested with HaeIII, HpaII, Sau3A, and the ADH3/ADH4-generated fragments digested with HaeIII, Sau3A, HhaI, RsaI. The MP P1 subtypes were determined based on resulting fragments. Part of samples were selected for sequencing. The clinical data of different MP subtype pneumonia were compared.</p><p><b>RESULT</b>A total of 300 hospitalized children with MP pneumonia were enrolled in this study. All the samples produced specific bands for MP P1 gene after PCR with primers of ADH1/ADH2 and ADH3/ADH4 respectively. By restrictive fragment length polymorphism analysis, 297 clinical specimens showed the characteristic band patterns for P1 type 1 identical to Mp129, and only 3 clinical specimens showed the characteristic band pattern for P1 type 2 identical to MP-FH. All P1 type 1 and P1 type 2 showed the same subtype bands respectively, as subtype 1b and 2a. After sequencing, one synonymous point mutation in P1 type 1 was identified relative to the MP129 P1 sequence at nucleotide position (nt) 208(G→A). Three cases with P1 type 2 MP pneumonia were found to have liver damage, and longer hospital stay and fever duration than P1 type 1, but no statistically significant difference was found.</p><p><b>CONCLUSION</b>Clinical samples can be used directly for genotyping of MP. The dominating type of MP in Zhejiang Province was P1 type 1 subtype 1b. But whether there was any relationship between MP subtype and clinical severity remains to be clarified.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effect of chlorogenic acid on disordered glucose and lipid metabolism in db/db mice and its mechanism.</p><p><b>METHODS</b>Thirteen 5-6-week-old male db/db mice were randomly divided into db/db-CGA group (n=7) and db/db-CON group (n=6), and thirteen 5-6-week-old male db/m mice were randomly divided into db/m-CGA group (n=6) and db/m-CON group (n=7). Mice in the CGA groups were administrated with CGA 80 mg/(kg·d)by gavage, and mice in the CON groups were administrated with PBS in the same volume by gavage. Twelve weeks later, the level of biomedical parameters in plasma, liver, and skeletal muscle were determined, the concentrations of adiponectin and visfatin in visceral adipose, and the mRNA expression of glucose-6-phosphatase (G-6-Pase) and peroxisome proliferators-activated receptor-α (PPAR-α) as well as the protein level of PPAR-α in liver were detected.</p><p><b>RESULTS</b>Twelve weeks after CGA administration, the levels of triglycerides in plasma, liver, and skeletal muscle and the fasting plasma glucose in db/db-CGA group were significantly lower than those in db/db-CON group(P<0.05). The muscle glycogen level was significantly higher than that in db/db-CON group (P<0.05), and the adiponectin concentration was significantly higher than that in db/db-CON group ( P<0.01) and lower than that in db/m-CGA group(P<0.05). The visfatin concentration in db/db-CGA group was significantly lower than that in db/db-CON group (P<0.01) and significantly higher than that in db/m-CGA group(P<0.05). The mRNA expression level of G-6-Pase was significantly down-regulated in db/db-CGA group when compared with db/db-CON group (P<0.05). Both the mRNA and the protein expression levels of PPAR-α were significantly up-regulated in db/db-CGA group(P<0.05) compared with in db/db-CON group.</p><p><b>CONCLUSION</b>CGA improves the disordered glucose/lipid metabolism in db/db mice, which is speculated to be related with its role in modulating the adipokines secretion, up-regulating hepatic PPAR-α, and inhibiting G-6-Pase expression.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expressions of metastasis-associated in colon cancer-1 (MACC1), hepatocyte growth factor (HGF), and C-met proteins in epithelial ovarian cancer and their significance.</p><p><b>METHODS</b>The expressions of MACC1, HGF and C-met in 20 specimens of normal ovarian tissues, 19 specimens of benign epithelial ovarian tumor and 52 specimens of epithelial ovarian cancer were measured by immunohistochemistry and Western blotting. The correlations of the expressions of MACC1, HGF and C-met protein to the clinicopathologic characteristics of epithelial ovarian cancer were analyzed, and the correlations between the expressions of the 3 proteins were also evaluated.</p><p><b>RESULTS</b>The positivity rates of MACC1, HGF and C-met proteins were 73.1%, 63.5% and 78.8% in epithelial ovarian cancer with relative expressions of 0.72∓0.05, 0.64∓0.04 and 0.79∓0.04, respectively, showing significant differences from those in normal ovarian tissues and benign ovarian tumors (P<0.05). In epithelial ovarian cancer, the up-regulation of MACC1, HGF and C-met expressions were associated with advanced FIGO stage, poor differentiation and lymph node metastasis (P<0.05). MACC1 expression was positively correlated to HGF (r=0.350, P=0.011) and C-met expressions (r=0.429, P=0.002), and the latter two was also positively correlated (r=0.487, P=0.000).</p><p><b>CONCLUSIONS</b>MACC1 may serve as a potential biomarker for advanced ovarian cancer. Deregulation of MACC1, HGF and C-met proteins may synergistically participate in the malignant progression of epithelial ovarian cancer.</p>

ABSTRACT

<p><b>BACKGROUND</b>The consumption of carbohydrate-electrolyte beverages (CEs) has been known to be more effective than plain water for recovery from dehydration. This phenomenon suggests that the ingestion of CEs after dehydration is better than water for maintaining body fluid and plasma volume, and for the recovery from hemoconcentration and high blood viscosity as well. High blood viscosity causes infarction and other cardiovascular events. In this study, CE was compared with water and tea for the ability to reduce increased blood viscosity after dehydration.</p><p><b>METHODS</b>A crossover random control study was conducted to assess the effectiveness of three beverages for rehydration and decreasing of blood viscosity. Following exercise-induced dehydration of 2.2% of body weight in a permanent warm environment, 10 male subjects rested in a thermoneutral environment for 3 hours (rehydration period, REP). The subjects ingested test beverages equal to their body weight loss during the first 20 minutes in REP. Blood and urine samples were obtained throughout the experiments to assess the rehydration effect.</p><p><b>RESULTS</b>The change in blood viscosity at a shear rate of 5/s was significantly lower in CE ((-1.66 ± 0.21) mPa×s) in comparison to water ((-0.95 ± 0.26) mPa×s) or tea ((-0.92 ± 0.14) mPa×s) at 60th minute during the REP. The fluid retention rate was significantly greater for CE ((77.0 ± 3.9)%) than water ((61.2 ± 3.4)%) and tea ((60.5 ± 3.7)%) for 3 hours of rest in REP.</p><p><b>CONCLUSIONS</b>The recovery from high blood viscosity induced by dehydration was higher with CE consumption than with water or tea. These results suggest that CE is useful for normalizing increased blood viscosity due to exercise-induced dehydration.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To reveal changes in clinical manifestations of Mycoplasma pneumoniae (Mp) pneumonia in children older than 3 years of age during 2000 - 2006.</p><p><b>METHOD</b>Totally 288 older children with Mp pneumonia hospitalized in the hospital between 2000 and 2006 were enrolled. Clinical manifestation, chest X-ray and clinical outcomes among three time periods (2000 - 2002, 2003 - 2004, 2005 - 2006) were compared.</p><p><b>RESULT</b>(1) Fever and its duration; 281 cases (97.6%) had fever of different duration (median = 7.2 d, 8.5 d, and 11.2 d, respectively) among the time periods, showing statistically significant difference (P < 0.01). (2) Respiratory symptoms: different incidence of wheezing/dyspnea (6.1%, 9.9%, 16.3%), thrilling (6.9%, 11.3%, 19.8%) and chest pain (12.2%, 15.5%, 22.1%) among different time periods had significant difference (χ(2) = 5.87, 11.46, 5.21, P < 0.05). (3) The incidence of extrapulmonary damages (13.0%, 38.0%, 48.8%) among different time periods also had significant difference (χ(2) = 21.27, P < 0.01). (4) Chest X-ray examination showed large area of lesions in most cases; 30.2% of cases seen during 2005 - 2006 were found having pulmonary complications such as pleural effusion or atelectasis. The incidences of pulmonary complications among different time periods had significant difference (P < 0.01). (5) TREATMENT AND OUTCOME: after comparing the efficacy of erythromycin or azithromycin, decline of clinical effectiveness was revealed among different time periods (P < 0.05). The duration of fever after macrolide administration (median = 3.2 d, 4.5 d, 6.2 d, respectively) and hospital stay (median = 7.0 d, 8.7 d, and 11.4 d, respectively) among different time periods showed significant differences (P < 0.05).</p><p><b>CONCLUSION</b>More refractory and severe Mp pneumonia cases appeared during 2000 - 2006 in children older than 3 years of age in Hangzhou, with prolonged fever duration, aggravated respiratory symptoms and more complications and extrapulmonary damages.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the epidemic characteristics of etiological agents in children with hand, foot and mouth disease (HFMD) and analyze the differences between the severe and mild cases with HFMD seen from 2008 to 2009 in the Children's Hospital.</p><p><b>METHODS</b>A total of 154 patients with HFMD were enrolled from May 2008 to September 2008 and from May 2009 to September 2009, including 28 severe HFMD patients. Data from 80 cases with suspected herpangina were collected as control. Enterovirus universal type, enterovirus type 71 (EV71) and coxsackie virus group A 16 (CA16) were detected by real-time RT-PCR respectively.</p><p><b>RESULTS</b>The positive rate of enterovirus universal type in the 154 patients with HFMD was 81.82%(126/154). EV71 positive rate in these 126 patients with enterovirus universal type infection was 57.14%(72/126). The positive rate of enterovirus universal type in the 80 cases with suspected herpangina was 68.75%(55/80). There was no EV71 infection in these 80 cases with suspected herpangina. EV71 infection was mainly popular in 2008. Both EV71 and CA16 were prevalent in 2009. The epidemic characteristics of enterovirus infection with HFMD between 2008 and 2009 had significant differences (χ(2) = 23.50, P = 0.000) (P < 0.01). The epidemic characteristics of enterovirus infection between severe and mild HFMD patients also had significant differences (χ(2) = 29.85, P < 0.01). There were 28 cases with severe HFMD, in whom the EV71 positive rate was 92.86% (26/28). EV71 positive rate in the mild HFMD was 36.51% (46/126) (χ(2) = 29.22, P < 0.01). There was no significant difference in the gender (χ(2) = 0.135, P = 0.714) and virus load (t = 0.141, P = 0.889) between the mild and severe HFMD cases. But the age of mild and severe HFMD showed a significant difference (t = 2.926, P = 0.009). Patients who were less than 2 years of age had a proportion of 88.89% (8/9) with severe HFMD. The mean age of mild HFMD patients was 3.19 years.</p><p><b>CONCLUSION</b>HFMD showed different epidemic characteristics at different times of enterovirus infection. There was no significant difference in the gender and virus load between the mild and severe cases with HFMD. Children under 3 years of age with EV71 infection were at high risk for severe HFMD.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To detect the expression of the protein of TGF-beta1 and E-cadherin in the primary and metastatic lesions of ovarian carcinoma and explore the mechanism of the metastasis of ovarian carcinoma.</p><p><b>METHODS</b>Immunohistochemistry (IHC) was performed to detect the expression of TGF-beta1 and E-cadherin proteins in primary and metastatic ovarian carcinoma, benign epithelial ovarian tumor and normal ovarian tissue.</p><p><b>RESULTS</b>The expression of TGF-beta1 was significantly higher in ovarian carcinoma (67.2%) than in benign tumors (28.6%) and normal ovarian tissue (18.9%) (Chi2=26.94, P<0.001), but E-cadherin expression showed a reverse pattern. TGF-beta1 expression in the primary ovarian carcinoma carcinoma was associated with the FIGO stage, lymph metastasis and ascites of the tumor (P=0.01, P=0.01, and P=0.04, respectively). E-cadherin expression in the tumor was associated with the differentiation (P=0.02) and lymph metastasis of ovarian carcinoma (P=0.04). The expressions of TGF-beta1 and E-cadherin were all significantly lower in the primary tumors than in the metastatic tumor (Chi2=4.70, P=0.03; Chi2=5.91, P=0.015). A significant correlation was found between the expressions of the TGF-beta1 and E-cadherin in the primary carcinoma (Kappa value of -0.32, P=0.01).</p><p><b>CONCLUSION</b>TGF-beta1 and E-cadherin are closely associated with the metastasis of ovarian carcinoma and might be potential targets for controlling the metastasis of ovarian carcinoma.</p>
