Abstract
Objective: To explore the optimal ratio of dihydrotestosterone and hydroxyflutamide (hereinafter referred to as DH), construct a dual release system of androgen and its antagonist, and analyze the application effect of this system in the repair of full-thickness burn wounds in mice. Methods: This study was an experimental study. The HaCaT cells were divided into blank group (without drug culture), low baseline group, medium baseline group, and high baseline group according to the random number table (the same grouping method below), and the last three groups of cells were cultured by adding three different ratios of DH. Under a medium ratio, the mass of dihydrotestosterone in the three baseline groups from low to high was 1.4, 2.8, and 4.0 µg, respectively, and the mass of hydroxyflutamide was 1.2, 1.6, and 2.0 µg, respectively. On this basis, under a small ratio, the mass of dihydrotestosterone was reduced by half and the mass of hydroxyflutamide was increased by half; under a large ratio, the mass of dihydrotestosterone was increased by half and the mass of hydroxyflutamide was reduced by half. After culture of 2 days, the cell proliferation level was detected by cell counting kit 8 (n=4). Sixteen 6-8-week-old male BALB/c mice were used to establish a full-thickness burn wound on the back and divided into blank group, small ratio group, medium ratio group, and large ratio group, with 4 mice in each group. On post injury day (PID) 7, normal saline containing different ratios of DH was locally dropped to the wounds of mice in the last three groups of mice (the total mass of DH in the three ratio groups from small to large was 127.5, 165.0, and 202.5 µg, respectively, and the mass ratios of dihydrotestosterone to hydroxyflutamide (hereinafter referred to as drug mass ratio) were 8∶9, 8∶3, and 8∶1, respectively), afterwards, the administration was repeated every 48 hours until PID 27; normal saline was dropped to the wound of mice in blank group at the aforementioned time points. The wound healing status on PID 0 (immediately), 7, 14, 21, and 28 was observed, and the wound healing rates on PID 7, 14, 21, and 28 were calculated (n=4). On PID 28, the wound tissue was taken, which was stained with hematoxylin and eosin for observing re-epithelialization and with Masson for observing collagen fibers, and the proportion of collagen fibers was analyzed (n=3). Twenty 6-8-week-old male BALB/c mice were used to establish a full-thickness burn wound on the back and divided into ordinary scaffold group, small proportion scaffold group, medium proportion scaffold group, and large proportion scaffold group (with 5 mice in each group). On PID 7, the wound was continuously dressed with a polycaprolactone scaffold without drug and a polycaprolactone scaffold containing DH with a drug mass ratio of 1∶3, 1∶1, or 3∶1 (i.e. the dual release system of androgen and its antagonist, with total mass of DH being about 1.7 mg) prepared by using electrospinning technology until the end of the experiment. Histopathological analyses of tissue (n=3) at the same time points as those in the previous animal experiment were performed. On PID 7 and 14, the wound exudates were collected and the relative abundance of bacterial communities was analyzed using 16S ribosomal RNA high-throughput sequencing (n=3). Results: After culture of 2 days, under a small ratio, the proliferation levels of HaCaT cells in low baseline group and high baseline group were significantly higher than the level in blank group (P<0.05). As the time after injury prolonged, the wounds of all four groups of mice continued to shrink. On PID 14, the wound healing rate of mice in large ratio group was 72.5% (61.7%, 75.1%), which was close to 53.3% (49.5%, 64.4%) in blank group (P>0.05); the wound healing rates of mice in small and medium ratio groups were 74.2% (71.0%, 84.2%) and 70.4% (65.1%, 74.4%), respectively, which were significantly higher than the rate in blank group (with both Z values being -2.31, P<0.05). On PID 21, the wound healing rate of mice in small ratio group was significantly higher than that in blank group (Z=-2.31, P<0.05). On PID 28, the wounds of mice in the three ratio groups were completely re-epithelialized and the epidermis was thicker than that in blank group; compared with that in blank group, the collagen fiber content in the wound tissue of mice in the three ratio groups was higher and arranged more orderly, and the proportions of collagen fibers in the wound tissue of mice in small and large ratio groups were significantly increased (P<0.05). On PID 28, the wounds of mice in ordinary scaffold group were partially epithelialized, while the wounds of mice in the three proportion scaffold groups were almost completely epithelialized. Among them, the wounds of mice in small proportion scaffold group had the thickest epidermis. The proportion of collagen fibers in the wound tissue of mice in small proportion scaffold group was significantly increased compared with that in ordinary scaffold group (P<0.05). On PID 7, the bacterial communities with high relative abundance in the wound exudation of mice in the four groups included bacteria of Corynebacterium, Staphylococcus, and Rhodococcus. On PID 14, the bacterial communities with high relative abundance in the wound exudation of mice in the four groups included bacteria of Stenotrophomonas, Rhodococcus, and Staphylococcus, and the number of bacterial species in the wound exudation of mice in the three proportion scaffold groups was more than that in ordinary scaffold group. Conclusions: When the drug mass ratio is relatively small, DH has the effect of promoting the proliferation of HaCaT cells. The ratio of 8∶9 is the optimal mass ratio of dihydrotestosterone to hydroxyflutamide, and DH with this mass ratio can promote re-epithelialization and collagen deposition of full-thickness burn wounds in mice, and promote wound healing. The constructed dual release system of androgen and its antagonist with DH in a 1∶3 drug mass ratio contributes to the re-epithelialization and collagen deposition of the full-thickness burn wounds in mice, and can improve the diversity of wound microbiota.

Abstract
Abstract
Background
We sought to investigate the relationship of left atrial appendage (LAA) mechanical dispersion (MD) with LAA dense spontaneous echo contrast (SEC) or thrombus, and to compare its usefulness in the identification of thrombogenesis with left atrial (LA) MD or LA/LAA strain parameters in patients with nonvalvular atrial fibrillation (AF).
Methods
We conducted a cross-sectional study of 493 consecutive patients with AF (median age 65, male 66.9%) who underwent echocardiography prior to catheter ablation. We measured the LAA and LA global longitudinal strain (GLS) using speckle-tracking echocardiography (STE). LAA MD and LA MD was defined as the standard deviation (SD) of time to peak positive strain corrected by the R-R interval.
Results
Patients with LAA dense SEC/thrombus (n=70) had significantly higher LAA MD than controls (n=423) (median 14.20% vs 9.35%). Areas under the receiver-operating curve for CHA2DS2-VASc score plus LAA MD, LAA GLS or LA GLS were comparable (0.830, 0.843 and 0.809) and superior to that combined with LA MD (0.762, all p<0.01). Multivariable analysis showed that LAA MD was an independent determinant of LAA dense SEC/thrombus in four different models (Odds ratio, 1.23–1.24; P<0.001), and provided additional diagnostic value over clinical and standard echocardiographic parameters. Whereas LA MD was not independently associated with LAA dense SEC/thrombus and had no incremental predictive value.
Conclusion
LAA mechanical dispersion provided incremental information over conventional risk factors in the identification of LAA dense SEC or thrombus in AF patients and is superior to LA mechanical dispersion.

Background
Left atrial (LA) and appendage (LAA) dysfunction were associated with increased risk of stroke in atrial fibrillation. However, usefulness of LA and LAA mechanics has not been fully compared. Methods:201 AF patients were prospectively enrolled. 42(20.8%) had previous stroke/TIA. Speckle tracking was used to measure LA and LAA peak postive strain. LA and LAA MD was defined as the SD of time to peak positive strain corrected by the R-R interval. Results:LA MD and LAA MD were independently associated with stroke/TIA. The model based on CHA2DS2-VASc score for discrimination of stroke was significantly improved by adding LA MD or LAA MD (P < 0.01). Diagnostic value of LA MD was better than LAA MD in patients with normal LA volumes, while LAA MD was more useful in patients with LA enlargement.Conclusion:Both LA and LAA mechanics had incremental value over CHA2DS2VASc score. However, priorities of strain assessment depend on patients’ LA volume.

Abstract
WHAT IS KNOWN AND OBJECTIVE In this study, the effectiveness of pharmaceutical care on treatment outcomes for patients with first-time pulmonary tuberculosis in China was assessed. METHODS In this study, patients were randomized either to the usual care (UC) group (n = 72) where patients received routine medical and nursing care or to the pharmaceutical care (PC) group (n = 59) where patients were simultaneously provided with pharmaceutical care. The primary objectives were to evaluate whether treatment outcomes and patient adherence improved more in the PC group than in the UC group. In addition, in PC group, outcomes included the number of patient-reported pharmaceutical care issues and pharmacists' interventions. RESULTS AND DISCUSSION As compared to the UC group, treatment success rate was improved in the PC group, but the difference was not statistically significant (71% vs 54%; P = 0.137). However, as compared to the UC group, the number of patients who attended all of the scheduled visits was higher in the PC group; the difference was statistically significant (81% vs 60%, P = 0.018). Furthermore, the number of patients who had positive test results for all of the isoniazid tests was higher in the PC group than in the UC group; the difference was also statistically significant (80% vs 50%, P = 0.002). The consumed medication rate was improved in the PC group, but no significant difference was found between the two groups. The patient-reported pharmaceutical care issues mainly included dermatological, gastrointestinal, hepatic, metabolic, sensory, central nervous system and haematological problems. On the basis of clinical examination, laboratory parameters and drug information database, the pharmacists addressed most of these pharmaceutical care issues. WHAT IS NEW AND CONCLUSION Pharmaceutical care might improve patient adherence for patients with first-time pulmonary tuberculosis in China, and further, rigorously controlled trials are required.

Abstract
Bifidobacterium preparations are increasingly used for pediatric antibiotic-associated diarrhea (AAD) in China. The aim of this study was to review existing evidence on the efficacy of Bifidobacterium preparations for the prevention and treatment of pediatric AAD in China. Searches were performed with Medline, Embase, Cochrane Central Register of Controlled Trials, CNKI, and CBM databases. Thirty trials met the inclusion criteria. Of the 30 trials, five Bifidobacterium preparations were included. The preparations were all Bifidobacterium based, in combined with Lactobacillus, Enterococcus, Bacillus, Streptococcus or Clostridium strains. The pooled results of the 30 trials, which included 7225 participants, indicated a statistically significant association of Bifidobacterium preparations administration with reduction in pediatric AAD (odds ratio [OR], 0.33; 95% confidence interval [CI], 0.29-0.39; P<0.01). When the meta-analysis was re-performed according to the trials explicitly aiming to prevent or treat pediatric AAD, respectively, the pooled results were similar (Bifidobacterium preparations use for preventing pediatric AAD (n=21): pooled OR, 0.34, 95% CI, 0.28-0.41, P<0.01; Bifidobacterium preparations use for treating pediatric AAD (n=9): pooled OR, 0.32, 95% CI, 0.23-0.43, P<0.01). Subgroup analyses which based on Bifidobacterium preparations variety, clinical condition, or participant's age also showed statistically significant benefit of adjunct Bifidobacterium preparations for the prevention and treatment of pediatric AAD in China. The pooled evidence suggested that Bifidobacterium preparations might be efficacious for the prevention and treatment of pediatric AAD in China.

Abstract
AIM OF STUDY There are multimodal and multidisciplinary approaches to treat diabetic peripheral neuropathy (DPN). However, the intractable adverse effects limited their widespread use. Chinese herbal medicine (CHM) is increasingly used for the treatment of DPN. The aim of this study was to review existing evidence on the effectiveness of CHM for the treatment of DPN. MATERIALS AND METHODS Searches were performed with Medline, Embase, Cochrane Central Register of Controlled Trials, CNKI, CBM and Wangfan databases. Controlled trials comparing CHM with other medicine for the treatment of DPN were analyzed. RESULTS Eighteen trials met the inclusion criteria. All trials used vitamin B12 and/or B1 as control. Clinical therapeutic effect, divided by three grades including marked effective, effective and ineffective according to the improved degree of subjective symptom, tendon reflex, and nerve conduction velocity, was the only end point reported in all trials, and thus evaluated. The results showed CHM treatment was associated with a superiority in marked effective (odds ratio [OR], 2.40; 95% confidence interval [CI]: 0.94 to 2.97; p<0.001), and effective (OR, 1.39; 95% CI: 1.16 to 1.67; p<0.001). Patients who received CHM treatment was associated with a less likely to report ineffective (OR, 0.26; 95% CI: 0.21 to 0.33, p<0.001). No adverse events were reported in any of the included trials. CONCLUSIONS According to the pooled results of our study and the poor quality of the included trials, it might be uncertainty that there was a superiority of CHM for treating DPN. More rigorous controlled trials are required to substantiate or refute these early findings.

Abstract
OBJECTIVES Multidrug-resistant tuberculosis (MDR-TB) has become an emerging global public health crisis. Several studies have suggested that pulmonary resection has efficacy in the treatment of MDR-TB. A systematic review of the available therapeutic studies was conducted to determine the treatment outcome among patients with MDR-TB who underwent pulmonary resection. METHODS To evaluate pulmonary resection for MDR-TB, a random-effect meta-analysis of the available studies was used to assess the overall treatment outcome. Subgroup analyses were also conducted by separating studies based on each characteristic independently. RESULTS After screening 4996 articles, 15 clinical reports with a mean of 63 patients per report met the inclusion criteria. Analysis of the studies showed that the estimated pooled treatment success rate of pulmonary resection for patients with MDR-TB was 84% [95% confidence interval (CI) 78%-89%]. The rates of failure, relapse, death and default were 6% (95% CI 4%-8%), 3% (95% CI 1%-4%), 5% (95% CI 2%-8%) and 3% (95% CI 1%-5%), respectively. The proportion of patients treated successfully did not differ significantly on the basis of any of the individual study characteristics. CONCLUSIONS Substantial heterogeneity in the study characteristics prevented a more conclusive determination of what factors had the greatest effect on the proportion of patients that achieve treatment success and limited the validity of this analysis. Some important variables, including patient HIV status, were inconsistently reported between studies. These results underscore the importance of strong patient support and treatment follow-up systems to develop successful MDR-TB treatment programmes.

Abstract
cDNA sequences of malate dehydrogenase (MDH) were cloned from various species, and MDH was identified to play an important role in cell energy metabolism. Here, we present the isolation and characterization of its homologue (OscMDH) in Oryza sativa. Comparison of the results to the genome details indicated that OscMDH consisted of seven exons. Sequence alignment showed that the deduced amino acid sequence of OscMDH shared a significant similarity with cMDH protein in Zea mays, as well as with other cMDH gene products. The different expression patterns of OscMDH in different tissues revealed that OscMDH mRNA was highly transcribed in either young panicle or immature seed, while its abundance was much low in green leaf and root. A nearly 56-kDa fusion protein generated by adding a Trx-His-tag at the N-terminal of OscMDH was induced by IPTG in Escherichia coli BL21 and an obvious MDH activity was detected in the protein by native PAGE analysis. All these results suggest that OscMDH encodes a cytosolic MDH in rice.

Skewed X-chromosome inactivation is associated with trisomy in women ascertained on the basis of recurrent spontaneous abortion or chromosomally abnormal pregnancies. Am J Hum Genet 2003; 72:399-407.

Abstract
An increase in extremely skewed X-chromosome inactivation (XCI) (> or = 90%) among women who experienced recurrent spontaneous abortion (RSA) has been previously reported. To further delineate the etiology of this association, we have evaluated XCI status in 207 women who experience RSA. A significant excess of trisomic losses was observed among the women who had RSA with skewed XCI versus those without skewed XCI (P=.02). There was also a significant excess of boys among live births in this group (P=.04), which is contrary to expectations if the cause of skewed XCI was only that these women carried X-linked lethal mutations. To confirm the association between skewed XCI and the risk of trisomy, an independent group of 53 women, ascertained on the basis of a prenatal diagnosis of trisomy mosaicism, were investigated. Only cases for which the trisomy was shown to be of maternal meiotic origin were included. The results show a significantly higher level of extreme skewing (> or = 90%) in women whose pregnancies involved placental trisomy mosaicism (17%) than in either of two separate control populations (n=102 and 99) (P=.02 compared with total control subjects). An additional 11 cases were ascertained on the basis of one or more trisomic-pregnancy losses. When all women in the present study with a trisomic pregnancy (n=103) were considered together, skewed XCI was identified in 18%, as compared with 7% in all controls (n=201) (P=.005). This difference was more pronounced when a cutoff of extreme skewing of 95% was used (10% vs. 1.5% skewed; P=.002). Maternal age was not associated with skewing in either the patient or control populations and therefore cannot account for the association with trisomy. Previous studies have shown that a reduced ovarian reserve is associated with increased risk of trisomic pregnancies. We hypothesize that the association between skewed XCI and trisomic pregnancies is produced by a common mechanism that underlies both and that involves a reduction of the size of the follicular pool.
