ABSTRACT

Objective::To compare the pharmacodynamic effects of pith-nodecayed and pith-decayed products of Scutellariae Radix on rats with large intestine damp-heat syndrome, and to demonstrate the scientificness of dividing Scutellariae Radix into pith-nodecayed and pith-decayed products as medicines by modern pharmacological test. Method::Rats were randomly divided into blank group, model group, low-and high-dose group of pith-nodecayed products (0.9, 3.6 g·kg-1), low-and high-dose group of pith-decayed products (0.9, 3.6 g·kg-1), Scutellariae Radix group (0.9 g·kg-1), compound berberine tablets group (positive drug group, 0.045 g·kg-1), and 8 rats in each group. Taking model rats with large intestine damp-heat syndrome, the body temperature, thymus index, spleen index, pathological sections of colon and ileum, inflammatory factors and Secretory immunoglobulin (SIg) A content were selected as indexes to evaluate the therapeutic effect of pith-nodecayed and pith-decayed products on large intestine damp-heat syndrome, and make comprehensive evaluation of the difference in efficacy between them. Partial least squares-discriminant analysis (PLS-DA) was employed to analyze the pharmacological indexes of these two products against large intestine damp-heat syndrome. Result::Pith-nodecayed and pith-decayed products of Scutellariae Radix with different doses could reduce the body temperature, thymus index, spleen index, contents of interleukin (IL)-2, IL-6, IL-1β in serum and SIgA content in intestinal mucosa, and most of them had significant differences (P<0.05, P<0.01). Compared with the isodose group of pith-decayed products, the effect of corresponding dose group of pith-nodecayed products was better, and most of them had significant differences (P<0.05, P<0.01). PLS-DA results indicated that there were significant differences in the pharmacological effects of pith-nodecayed and pith-decayed products, and they were clustered on one side, respectively. Conclusion::Both of pith-nodecayed and pith-decayed products of Scutellariae Radix have therapeutic effect on large intestine damp-heat syndrome with distinctly different strength of action, and pith-nodecayed products is superior to pith-decayed products, which verify the scientific nature of pith-nodecayed products was specializedly used to treat bowel disease in ancient times.

ABSTRACT

Objective:To explore the validity of Achilles Tendon Total Rupture Score (ATRS) for rehabilitation after Achilles tendon rupture. Methods:From January, 2012 to December, 2016, 50 patients with acute Achilles tendon rupture were enrolled. The original table of ATRS was translated, organized and evaluated to obtain the ATRS consensus version. At the 1st month, 2nd month, 3rd month, 6th month and 12th month follow-up, the scores of American Orthopaedic Foot and Ankle Society Ankle-hindfoot scale (AOFAS-AH) and ATRS were recorded. Results:Three patients were dropped out. The scores of both AOFAS-AH and ATRS increased with time, and gradually became flat. The total score of AOFAS-AH was significantly positively correlated with the total score of ATRS (ρ = 0.961, P < 0.001). Conclusion:ATRS can be used in evaluating the functional recovery of Achilles tendon repair.

ABSTRACT

OBJECTIVE: The present study aimed to investigate the relationship between obesity and mortality in patients with community-acquired pneumonia (CAP) in China. METHODS: In total, 909 patients with CAP were recruited for this study from January 2010 to June 2015. All patients were selected and divided into 4 groups according to their body mass index (BMI) values. All patients' clinical information was recorded. The associations among mortality; BMI; the 30-day, 6-month and 1-year survival rates for different BMI classes; the etiology of pneumonia in each BMI group; and the risk factors for 1-year mortality in CAP patients were analyzed. RESULT: With the exception of the level of C-reactive protein (CRP), no other clinical indexes showed significant differences among the different BMI groups. No significant differences were observed among all groups in terms of the 30-d and 6-month mortality rates (p>0.05). There was a significantly lower risk of 1-year mortality in the obese group than in the nonobese group, (p<0.05). Logistic regression analysis showed that there were seven independent risk factors for 1-year mortality in CAP patients, namely, age, cardiovascular disease, cerebrovascular disease, obesity, APACHE II score, level of CRP and CAP severity. CONCLUSION: Compared with nonobese patients with CAP, obese CAP patients may have a lower mortality rate, especially with regard to 1-year mortality, and CRP may be associated with the lower mortality rate in obese individuals than in nonobese individuals.

ABSTRACT

@#Objective We probed how to predict left ventricular ejection fraction (LVEF) of the ischaemic cardiomyopathy (ICM) patients would be improved apparently after revascularization. Methods Between July 2010 and December 2015, 245 ICM patients (30%≤LVEF≤40%) with coronary bypass grafting (CABG) were retrospectively observed. Among them, 146 patients were accompanied by ischemic mitral regurgitation (IMR) (146/245, 59.6%), and 41 patients underwent mitral valvuloplasty or replacement because of more than moderate IMR. There were 13 patients early death, and other 232 patients who were followed up over 6 months were divided into two groups based on whether or not post-operative LVEF increased by 10%: a LVEF recovered group (group A, 124 patients) and a non-recovered group (group B, 108 patients). Results Preoperative NT-proBNP in the group A was significantly higher than that in the group B (P=0.036). There were less patients with myocardial infarction in the group A than that in the group B (P=0.047), and more with angina pectoris in the group A than that in the group B (P=0.024). There was no significant difference in the extent of mitral regurgitation or mitral surgery between the groups A and B (P>0.05). There were lower left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD) and left ventricular end-diastolic volume (LVEDV) in the group A than those in the group B (P<0.05). Multivariate analysis revealed that preoperative LVEDD dilated apparently and no angina pectoris existed before surgery were independent risk factors for LVEF with no recovery in the ICM patients (30%≤LVEF≤40%) after revascularization. The LVEDD of 245 patients (including 13 early deaths) was 41-71 mm. We found that the ICM patients with LVEDD ≥60 mm were more likely to signify the unfavourable prognosis (χ2=8.63, P=0.003, OR=2.21, 95% confidence interval 1.25 to 3.91). Conclusion Preoperative LVEDD dilated and no angina pectoris before surgery are independent risk factors for LVEF with no recovery in the ICM patients (30%≤LVEF≤40%) after revascularization. LVEDD≥60 mm can be regarded as the preoperative forecasting factors for the unfavourable prognosis in the ICM patients (30%≤LVEF≤40%) after revascularization.

ABSTRACT

<p><b>OBJECTIVE</b>To determine Cronobacter spp. contamination in infant and follow-up powdered formula in China.</p><p><b>METHODS</b>All of 2282 samples were collected from the retail markets in China from January 2012 to December 2012, and analyzed for Cronobacter spp. by the Chinese National Food Safety Standard. Characterization of the isolates was analyzed by pulsed-field gel electrophoresis (PFGE) with XbaI and SpeI restriction enzymes.</p><p><b>RESULTS</b>Cronobacter spp. strains were isolated from 25 samples, and the positive rates in infant powdered formulas and follow-up powdered formulas were 0.90% (10/1011) and 1.18% (15/1271), respectively. Analysis of variable data regarding different purchasing store formats, seasonality, and production locations as well as comparison of infant versus follow-up formulas did not reveal statistically significant factors. During the sampling period, one of six surveillance zones did exhibit a statistically significant trend towards higher positive rate. PFGE characterization of Cronobacter spp. to elucidate genetic diversity revealed only three pairs of Cronobacter spp. out of 25 having the same PFGE patterns.</p><p><b>CONCLUSION</b>The current investigation indicated a lower positive rate of Cronobacter spp. in the powdered formula in China. This evidence suggested contamination originating from multiple different sources during the manufacturing process.</p>

ABSTRACT

Based on the recently proposed Chinese ischemic stroke subclassification (CISS) system, intracranial branch atheromatous disease (BAD) is divided into large artery atherosclerosis (LAA) and penetrating artery disease (PAD). In the current retrospective analysis, we compared the general characteristics of BAD-LAA with BAD-PAD, BAD-LAA with non-BAD-LAA and BAD-PAD with non-BAD-PAD. The study included a total of 80 cases, including 45 cases of BAD and 35 cases of non-BAD. Subjects were classified using CISS system: BAD-LAA, BAD-PAD, non-BAD-LAA and non-BAD-PAD. In addition to analysis of general characteristics, the correlation between the factors and the two subtypes of BAD was evaluated. The number of cases included in the analysis was: 32 cases of BAD-LAA, 13 cases of BAD-PAD, 21 cases of non-BAD-LAA, and 14 cases of non-BAD-PAD. Diabetes mellitus affected more non-BAD-LAA patients than BAD-LAA patients (P=0.035). In comparison with non-BAD-PAD, patients with BAD-PAD were younger (P=0.040), had higher initial NIHSS score (P<0.001) and morbidity of ischemic heart disease (P=0.033). Within patients with BAD, the PAD subtype was associated with smoking (OR=0.043; P=0.011), higher low-density lipoprotein (OR=5.339; P=0.029), ischemic heart disease (OR=9.383; P=0.047) and diabetes mellitus (OR=12.59; P=0.020). It was concluded that large artery atherosclerosis was the primary mechanism of BAD. The general characteristics showed no significant differences between the CISS subtypes of LAA and PAD within BAD, as well as between the BAD and non-BAD within LAA subtype. Several differences between PAD subtypes of BAD and non-BAD were revealed.

ABSTRACT

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and TACE alone for hepatocellular carcinoma (HCC), Pubmed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Datebases were searched for the randomized controlled trials (RCTs) and retrospective cohort studies from the establishment of the databases to January 2014. The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were undertaken, we performed this meta-analysis by using the RevMan5.2 software. Seventeen studies involving 1116 patients met the inclusion criteria with 530 treated with RFA-plus-TACE and 586 with TACE alone. The results of meta-analysis showed that the combination of TACE and RFA was obviously associated with higher 1-, 2-, and 3-year overall survival rates (OR1-year=3.98, 95% CI 2.87-5.51, P<0.00001; OR2-year=3.03, 95% CI 2.10-4.38, P<0.00001; OR3-year=7.02, 95% CI 4.14-11.92, P<0.00001) than TACE alone. The tumor complete necrosis rate in patients treated with TACE and RFA was higher than that of TACE alone (OR=13.86, 95% CI 8.04-23.89, P<0.00001). And there was a significant difference in local recurrence rate between two different kinds of treatment (OR=0.24, 95%CI 0.14-0.44, P<0.00001). Additionally, combination of TACE and RFA was associated with higher complete tumor necrosis rates than TACE mono-therapy in the treatment of HCC. However, RFA plus TACE was found to be associated with a lower local recurrence rate than TACE monotherapy. TACE-plus-RFA treatment was associated with a higher response rate (RR) than the TACE-alone treatment (OR=3.90, 95% CI=2.37-6.42, P<0.00001). TACE-plus-RFA treatment did not differ from the TACE-alone treatment in terms of stable disease (SD) rate (OR=0.38, 95% CI=0.11-1.26, P=0.11). Meta-analyses showed that the combination of RFA and TACE was associated with a significantly lower progressive disease (PD) rate (OR=0.15, 95% CI=0.05-0.43, P=0.0005). The rate of AFP reducing or returning to normal in serum in RFA plus TACE group was obviously lower than TACE alone group (OR=4.62, 95% CI 2.56-8.34, P<0.00001). The effect of TACE plus RFA for HCC is better than TACE mono-therapy. The combined therapy can elevate the patients' overall survival rate, tumor necrosis rate and the rate of AFP reducing or returning to normal in serum and decrease local recurrence rate, PD rate compared with TACE alone.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the value of multiple b-value diffusion-weighted imaging (DWI) for differentiation of benign and malignant pulmonary masses.</p><p><b>METHODS</b>Thirty-eight patients were examined by routine sequences and DWI pulse sequence. DWI was acquired through a single-shot echo-planar imaging combined with a respiratory-triggered mode and parallel acquisition. Nine b values ranging from 0 to 1500 s/mm(2) (0, 50, 100, 150, 200, 400, 600, 1000, 1500 s/mm(2)) were used. The intravoxel incoherent motion model was applied to estimate pure diffusion coefficient D, perfusion-related diffusion coefficient D(*), and perfusion fraction f. Mann-Whitney U test was used to compare all measured parameters between benign and malignant groups. The diagnostic performance of the related parameters was evaluated with receiver operating characteristics (ROC) analysis.</p><p><b>RESULTS</b>Of these 38 patients, 30 were pathologically confirmed and 8 were diagnosed based on clinical data. There were 23 lung malignant masses and 15 benign lesions. A significant reduction of D was found in malignant group than in benign group (Z=3.308, P=0.001), while no significant differences in D(*)(Z=1.646, P=0.100) and f(Z=1.254, P=0.210) were observed between the two groups. The area under the ROC curve for D value (0.839) was largest. When the cutoff value was selected as 0.90×10(-3) mm(2)/s, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of diagnosing malignant masses were 95.7%, 80.0%, 90.9%, 91.7%, and 88.9%,respectively.</p><p><b>CONCLUSION</b>The D value in multiple b-value DWI has certain significance in differentiating the benign and malignant pulmonary masses and has the best diagnostic efficiency.</p>

ABSTRACT

Lysophosphatidyl acyltransferase (LPAT) is the important enzyme responsible for the acylation of lysophosphatidic acid (LPA), leading to the generation of phosphatidic acid (PA) in plant. Its encoding gene is an essential candidate for oil crops to improve oil composition and increase seed oil content through genetic engineering. In this study, a fulllength AhLPAT4 gene was isolated via cDNA library screening and rapid amplification of cDNA ends (RACE); our data demonstrated that AhLPAT4 had 1631 nucleotides, encoding a putative 43.8 kDa protein with 383 amino acid residues. The deduced protein included a conserved acyltransferase domain and four motifs (I–IV) with putative LPA and acyl-CoA catalytic and binding sites. Bioinformatic analysis indicated that AhLPAT4 contained four transmembrane domains (TMDs), localized to the endoplasmic reticulum (ER) membrane; detailed analysis indicated that motif I and motifs II–III in AhLPAT4 were separated by the third TMD, which located on cytosolic and ER luminal side respectively, and hydrophobic residues on the surface of AhLPAT4 protein fold to form a hydrophobic tunnel to accommodate the acyl chain. Subcellular localization analysis confirmed that AhLPAT4 was a cytoplasm protein. Phylogenetic analysis revealed that AhLPAT4 had a high homology (63.7–78.3%) with putative LPAT4 proteins from Glycine max, Arabidopsis thaliana and Ricinus communis. AhLPAT4 was ubiquitously expressed in diverse tissues except in flower, which is almost undetectable. The expression analysis in different developmental stages in peanut seeds indicated that AhLPAT4 did not coincide with oil accumulation.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the operative technique and results with the usage of cementless prosthesis in hip revision.</p><p><b>METHODS</b>Retrospective study was done on revision of total hip arthroplasty with cementless prosthesis in 72 patients (41 males and 31 females) with an average age of 65.7 years (28-82 years) from January 2004 to December 2009. The reason for revision was 2 infection, 54 aseptic loosening, 4 periprosthetic fractures, 5 fracture of femoral stems and 7 cases of acetabular abrasion after hemi-arthroplasty. The operation time, bleeding loss, complications of infection, dislocation, periprosthetic fractures and loosening were evaluated. The Harris score were used for hip function evaluation.</p><p><b>RESULTS</b>The average operation time was (146±47) minutes (70-280 minutes) and bleeding loss during the operation was (970±540) ml (200-2500 ml). Bacterium cultivation during operation demonstrated infection in 2 patients. Bone windows at the lateral femoral were opened in 4 patients and extend trochanteric osteotomy was done in 7 patients. Fracture of the proximal femur occurred in 8 cases. Twenty-nine patients were treated with bone graft including 18 autografts and 11 allografts. Sixty-seven patients were followed up for an average time of 66 months (20-92 months). Additional revisions were performed in 3 cases including 2 dislocations and 1 infection. There were no death, no damage of major blood vessels and nerves. The bone graft healed during 3-5 months. The survival rates of the femoral prosthesis and the acetabulum prostheses were 95.5% and 98.4%. The mean Harris score was 86±8 (55-95 points). Osteolysis were seen in 13 hips but migration was seen in only 1 patient.</p><p><b>CONCLUSIONS</b>The cementless prosthesis is useful in revision total hip arthroplasty and the perfect clinical results are related to the reliable primary fixation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate dietary iodine intake and its potential risks among the Chinese population.</p><p><b>METHODS</b>Individual dietary iodine intake was calculated using food consumption data multiplying by iodine concentration in foods, table salt and drinking water, followed by summing, and then compared with the corresponding age-specific reference values, including Upper Intake Level (UL) and Recommended Nutrient Intake (RNI).</p><p><b>RESULTS</b>In areas with water iodine concentration (WI) lower than 150 μg/L, 80.8% of residents had iodine intake between the RNI and UL, 5.8% higher than UL, and the remaining (13.4%) lower than RNI if iodized salt was consumed. However, in the uniodized salt consumption scenario, only 1.0% of residents between RNI and UL, 1.4% higher than UL, and a large part of residents (97.6%) lower than RNI. In areas with WI higher than 150 μg/L, all residents had iodine intake between RNI and UL if iodized salt was consumed, except 10.5% and 24.9% of residents higher than UL in areas with WI at 150-300 μg/L and higher than 300 μg/L respectively. However, in the uniodized salt consumption scenario, only 1.5% and 1.7% of residents had higher iodine intake than UL respectively.</p><p><b>CONCLUSION</b>The findings suggested that in general, the dietary iodine intake by the Chinese population was appropriate and safe at the present stage. People in areas with WI lower than 150 μg/L were more likely to have iodine deficiency.

ABSTRACT

In recent years, studies of large-scale systematic evaluation on clinical effectiveness of acupuncture were carried out in overseas. The literatures were conducted in Cochrane Library and overseas journals about systematic review of clinical effectiveness of acupuncture. The Cochrane Library contained a series of systematic reviews for the treatment of 67 kinds of diseases by acupuncture in 2009. Preliminary evaluations of clinical effectiveness of acupuncture on 37 kinds of disease were conducted. The results indicated that acupuncture therapy was effective for 7 kinds of disease, such as idiopathic headache, neck disorders, glaucoma, rheumatoid arthritis, chemotherapy-induced nausea or vomiting, primary dysmenorrhoea with TENS and knee osteoarthritis with TENS. However, these studies still need improved research designs and sufficient research evidence. The results also indicated that acupuncture was indecisive for the other 30 kinds of disease because of insufficient evidence. Through analysis, results of most systematic reviews indicated that there were no significant difference between therapeutic effects of acupuncture treatment and pseudo-acupuncture treatment. Effect of acupuncture treatment was equivalent to therapeutic effect of placebo. The likely reasons may be that some important clinical factors are disregarded in these researches, such as selection of acupoints, treatment with syndrome differentiation, the angel and depth of needle insertion, the proper time for treatment and so on. Therefore, the large-scale systematic evaluation on clinical effectiveness of acupuncture was criticized by acupuncturists. Thus, the pressing problem is to establish a rational evaluation system of clinical acupuncture. The suggestions are strengthening the research on diagnosis and treatment standard, strengthening the quality control of clinical acupuncture and establishing sound acupuncture control group and placebo acupuncture group. The basic researches on the relationship between diseases and acupoints need to be strengthened in order to explore the mechanism of acupoints reaction on diseases.

ABSTRACT

The identification of expressed genes involved in sexual precocity of the mitten crab (Eriocheir sinensis) is critical for a better understanding of its reproductive development. To this end, we constructed a cDNA library from the rapid developmental stage of testis of E. sinensis and sequenced 3,388 randomly picked clones. After processing, 2,990 high-quality expressed sequence tags (ESTs) were clustered into 2,415 unigenes including 307 contigs and 2,108 singlets, which were then compared to the NCBI non-redundant (nr) protein and nucleotide (nt) database for annotation with Blastx and Blastn, respectively. After further analysis, 922 unigenes were obtained with concrete annotations and 30 unigenes were found to have functions possibly related to the process of reproduction in male crabs - six transcripts relevant to spermatogenesis (especially Cyclin K and RecA homolog DMC1), two transcripts involved in nuclear protein transformation, two heat-shock protein genes, eleven transcription factor genes (a series of zinc-finger proteins), and nine cytoskeleton protein-related genes. Our results, besides providing valuable information related to crustacean reproduction, can also serve as a base for future studies of reproductive and developmental biology.

ABSTRACT

BACKGROUND: Serum creatinine (SCr) is the most commonly used parameter to estimate renal function impairement, but there are some shortcomings. Many factors including age, gender, drug, diet, muscle mass and metabolic rate can influence SCr, leading to an inaccurate estimation of kidney impairment. Studies have shown that cystatin C (CysC) is not affected by factors such as muscle mass, age, gender, diet, inflammation or tumor. The present study was undertaken to compare the sensitivity of CysC and SCr in evaluating renal function impairment at early stage of shock. METHODS: Seventy-one patients aged 38.3±21.4 years, who had been treated at the Emergency Medicine Department of the First Affiliated Hospital, Sun Yat-sen University between February 2006 and June 2007, were studied. They were divided into groups A, B, C, and D according to the shock time. Serum sample was drawn from each patient at 1, 2, 3, 4 hours after shock to determine SCr and CysC. CysC and SCr were determined again at 72 hours and 7 days after shock. RESULTS: CysC increased earlier than SCr in the 71 patients, and CysC decreased slower than SCr when shock was corrected. CysC increased at 1 hour after shock. There was a negative correlationship between CysC, SCr and glomerular filtration rate (GFR), especially at early stage of shock. CONCLUSIONS: There is renal injury at early stage of shock. CysC is more sensitive than SCr in assessing renal function at the early stage of shock.

ABSTRACT

To investigate whether glutamate and voltage-gated calcium channels-independent calcium influx exists during acute anoxic neuronal damage and its possible relationship to neuronal protective function of NGF. In in vitro model of acute anoxia, hippocampal cultures from newborn rats were exposed to 3 mmol/L KCN. Changes of intracellular Ca2+ concentration ([Ca2+]i) were monitored by con-focal imaging and cell viability was assayed by PI and cFDA staining. The results showed that after treatment with primary hippocampal cultures with 3 mmol/L KCN for 15 min,[Ca2+]i was significantly increased 6.27-fold compared to pre-anoxia level and 73.3% of the cells died.When combination of 20 μmol/L MK-801 (glutamate receptor antagonist), 40 μmol/L CNQX (AMPA receptor antagonist) and 5 μmol/L nimodipine (voltage-gated calcium channel antagonist) (hereafter denoted as MCN) were administrated to hippocampal cultures, levels of [Ca2+]i and cell death rate induced by KCN were partially reduced by 35.9% and 47.5% respectively. However, Gd3+ (10μmol/L) almost completely blocked KCN-mediated [Ca2+]i elevation by 81.9% and reduced neuronal death by 88.8% in the presence of MCN. It is noteworthy that NGF, used in combination with MCN,inhibited KCN-induced [Ca2+]i increase by 77.4% and reduced cell death by 87.1%. Only PLC inhibitor U73122 (10 μmol/L) abolished NGF effects. It is concluded that Gd3+-sensitive calcium influx,which is NMDA (glutamate receptor) and voltage-gated calcium channels-independent, is responsible for acute anoxic neuronal death. NGF can inhibit Gd3+-sensitive calcium influx and reduce anoxic neuronal death through activating PLC pathway.
