Abstract
Gastroesophageal reflux-related cough (GERC) is an extra-esophageal manifestation of gastroesophageal reflux disease (GERD) and a common cause of chronic cough. GERC is the most difficult of the chronic cough to diagnose and treat because of its lack of specificity and its multidisciplinary nature. In recent years, research into GERC has led to a consensus on many key issues. The 2021 edition of the Guidelines for the Diagnosis and Treatment of Cough (Cough guidelines) provides important guidance on the diagnosis and treatment of GERC. However, the surgical treatment of GERC is not well covered in the Cough guidelines. This article summarizes the surgical treatment of GERC in terms of surgical methods, current situation, indications for operation and curative effects.

Abstract
Objective: To investigate the clinical efficacy of local injection of platelet-rich plasma (PRP) combined with double-layer artificial dermis in treating wounds with exposed tendon on extremity. Methods: A retrospective observational study was conducted. From December 2017 to October 2022, 16 patients were admitted to Department of Orthopaedic Trauma of the Second Affiliated Hospital of Guizhou University of Traditional Chinese Medicine, and 32 patients were admitted to Department of Burns and Plastic Surgery of Guiyang Steel Factory Staff Hospital. All the patients had wounds with exposed tendon on extremity caused by various reasons and met the inclusion criteria. There were 39 males and 9 females, aged 26 to 58 years. The patients were divided into PRP alone group, artificial dermis alone group, and PRP+artificial dermis group, with 16 patients in each group. The wounds were treated with autologous PRP, double-layer artificial dermis, or thei combination of autologous PRP and double-layer artificial dermis, followed by autologous split-thickness scalp grafting after good growth of granulation tissue. On the 7th day after the secondary surgery, the autograft survival was observed, and the survival rate was calculated. The wound healing time and length of hospital stay of patients were recorded. At 3 and 6 months after wound healing, the Vancouver scar scale (VSS) was used to score the pigmentation, height, vascularity, and pliability of scars, and the total score was calculated. Adverse reactions during the entire treatment process were recorded. Data were statistically analyzed with chi-square test, Fisher's exact probability test, one-way analysis of variance, least significant difference test, Kruskal-Wallis H test, Nemenyi test, and Bonferroni correction. Results: On the 7th day after the secondary surgery, there was no statistically significant difference in the autograft survival rate of patients among PRP alone group, artificial dermis alone group, and PRP+artificial dermis group (P>0.05). The wound healing time and length of hospital stay of patients in PRP+artificial dermis group were (20.1±3.0) and (24±4) d, respectively, which were significantly shorter than (24.4±5.5) and (30±8) d in PRP alone group (P<0.05) and (24.8±4.9) and (32±8) d in artificial dermis alone group (P<0.05). At 3 and 6 months after wound healing, the pliability scores of patients in PRP+artificial dermis group were significantly lower than those in PRP alone group (with Z values of 12.91 and 15.69, respectively, P<0.05) and artificial dermis alone group (with Z values of 12.50 and 12.91, respectively, P<0.05). There were no statistically significant differences in pigmentation, vascularity, height scores, and total score of scar of patients among the three groups (P>0.05). In artificial dermis alone group, one patient experienced partial liquefaction and detachment of the double-layer artificial dermis due to local infection of Staphylococcus epidermidis, which received wound dressing change, second artificial dermis transplantation, and subsequent treatment as before. No adverse reactions occurred in the remaining patients during the whole treatment process. Conclusions: Local injection of PRP combined with double-layer artificial dermis is effective in treating wounds with exposed tendon on extremity, which can not only significantly shorten wound healing time and length of hospital stay, but also improve scar pliability after wound healing to some extent in the long term. It is a clinically valuable treatment technique that is worth promoting and applying.

Abstract
Objective: To investigate the risk and influencing factors of long-term mortality of valvular heart disease (VHD) adults aged 35 years and over in Chinese communities. Methods: A cohort study was carried out. The data of the subjects who underwent echocardiography were collected from the Chinese Hypertension Survey between 2012 and 2015 and survival outcomes were followed up between 2018 and 2019. Kaplan-Meier survival curves were plotted and compared using log-rank test. Cox proportional hazards models were used to analyze the influence of VHD on mortality. Results: During an average follow-up time of (4.6±0.9) years, a total of 23 237 participants (10 881 males and 12 356 females) were pooled into the final analysis from 5 eastern, 5 central, and 4 western provinces, cities and autonomous regions in China, with a mean age of (56.9±13.2) years. Among the included participants, 1 004 had VHD (467 males and 537 females), with a mean age was of (68.1±12.6) years. In the Kaplan-Meier analysis, participants with VHD had a significantly increased risk of all-cause mortality (log-rank χ2=351.82, P<0.001) and cardiovascular mortality (log-rank χ2=284.14, P<0.001) compared with those without VHD. Multivariate Cox regression analysis showed that compared with those without VHD, the participants with rheumatic VHD had a 45% increased risk of all-cause mortality (HR=1.45, 95%CI: 1.12-1.89) and degenerative VHD increased the risk of cardiovascular mortality by 69% (HR=1.69, 95%CI: 1.19-2.38). The risk factors of cardiovascular mortality for VHD were age 55 years and over (55-<75 years: HR=4.93, 95%CI: 1.17-20.85;≥75 years: HR=11.92, 95%CI: 2.85-49.80) and diabetes mellitus (HR=1.71, 95%CI: 1.00-2.93). Conclusions: VHD is a risk factor of all-cause mortality and cardiovascular mortality among adults aged 35 years and over. Age 55 years and over and diabetes mellitus are adverse prognostic factors for patients with VHD.

Abstract
Hydrofluoric acid is a highly dangerous and toxic inorganic acid, which is widely used in industrial fields and daily life. The risk of hydrofluoric acid burns is related to hydrofluoric acid mass fraction, duration of exposure to hydrofluoric acid, burn area, burn depth, and burn site, etc. Hydrofluoric acid has strong toxicity and tissue penetration ability. A small area of hydrofluoric acid burns can cause death in a short time. Therefore, improving the understanding of the mechanism of hydrofluoric acid burns and learning how to treat hydrofluoric acid burns in different sites can further improve the cure rate of hydrofluoric acid burns.

Abstract
Objective: To investigate the molecular mechanism of oxaliplatin-induced chemotherapy-induced peripheral neuropathic pain (CIPNP). Methods: A total of 16 male Sprague-Dawley rats of specific pathogen-free grade were randomly divided into two groups: oxaliplatin experimental group (2.4 mg/kg oxaliplatin dissolved in 5.0% glucose solution, n=8) and control group (equal volume 5% glucose solution, n=8). The rat model of CIPNP was established by continuous administration with oxaliplatin. In addition, mechanical allodynia, thermal hyperalgesia and cold hyperalgesia were measured and compared between the two groups. To explore the molecular mechanism of oxaliplatin-induced CIPNP, the gene expression of dorsal root ganglia (DRG) from the rat model of CIPNP was analyzed using RNA sequencing (RNA-Seq). Results: Mechanical and thermal hypersensitivity was exhibited on day 7 and a stronger hypersensitivity was observed on day 14. A total of 20 152 genes were quantified by RNA-Seq, and 379 differentially expressed genes (DEGs) were obtained with absolute fold change cut-offs ≥ 2 and P value<0.05. There were 7 genes (Npy, Car3, Cdkn1a, Nts, Prc1, Ms4a7 and Ecel1) that were involved in peripheral nerve injury-related neuropathic pain. Gene ontology (GO) functional enrichment analyses indicated that the DEGs induced by oxaliplatin were involved in oxygen transport, cell division, intermediate, centromere, oxygen transporter activity, oxygen binding. Moreover, the result of Kyoto Encyclopedia of genes and genomes (KEGG) analyses highlighted that the DEGs induced by oxaliplatin were involved in malaria, African trypanosomiasis, primary immunodeficiency, peroxisome proliferator activated receptor (PPAR) signaling pathway. Conclusion: Oxaliplatin induces CIPNP via pain-related genes and signaling pathways.

Abstract
PURPOSE The aim of this study was to design and fabricate a three-dimensional (3D) printed artificial ovary. METHODS We first compared the printability of gelatin-methacryloyl (GelMA), alginate and GelMA-alginate bioinks, of which GelMA was selected for further investigation. The swelling properties, degradation kinetics and shape fidelity of GelMA scaffolds were characterized by equilibrium swelling/lyophilization, collagenase processing and micro-computed tomography evaluation. Commercial ovarian tumor cell lines (COV434, KGN, ID8) and primary culture ovarian somatic cells were utilized to perform cell-laden 3D printing, and the results were evaluated by live/dead assays and TUNEL detection. Murine ovarian follicles were seeded in the ovarian scaffold and their diameters were recorded every day. Finally, in vitro maturation was performed, and the ovulated oocytes were collected and observed. RESULTS Our results indicated that GelMA was suitable for 3D printing fabrication. Its scaffolds performed well in terms of hygroscopicity, degradation kinetics and shape fidelity. The viability of ovarian somatic cells was lower than that of commercial cell lines, suggesting that extrusion-based 3D culture fabrication is not suitable for primary ovarian cells. Nevertheless, the GelMA-based 3D printing system provided an appropriate microenvironment for ovarian follicles, which successfully grew and ovulated in the scaffolds. Metaphase II oocytes were also observed after in vitro maturation. CONCLUSIONS The GelMA-based 3D printing culture system is a viable alternative option for follicular growth, development and transfer. Accordingly, it shows promise for clinical application in the treatment of female endocrine and reproductive conditions.

Abstract
Objective: To investigate the effect of a novel laparoscopic W-H fundoplication in the treatment of proton pump inhibitor (PPI) dependent gastroesophageal reflux disease (GERD). Methods: The clinical data of PPI dependent GERD patients who underwent laparoscopic W-H fundoplication in PLA Rocket Force Characteristic Medical Center from October 1st, 2018 to April 30th, 2019 were analyzed retrospectively. The GERD symptom score, subjective symptom relief, PPI withdrawal, efficacy satisfaction and postoperative complications were followed up and analyzed by a questionnaire. Results: A total of 80 GERD patients were included in this study, and 49 were male and 31 were female, with a median age of 58 years. Among all patients, 85% (68/80) are with esophagitis and 77.5% (62/80) with hiatal hernia. The operation time was 67 (52, 73) minutes, without intraoperative complications and conversion to laparotomy. The postoperative follow-up period was 16 (14, 18) months. The postoperative GERD symptom scores were significantly lower than those before surgery, with an statistical difference (all P<0.05). The subjective remission degree of the overall digestive and respiratory symptoms were 100 (90, 100)% and 100 (80, 100)%, respectively. During the follow-up period, the PPI discontinuation rate was 83% (69/80), and the satisfactory rate was 93% (75/80). Postoperative complications included dysphagia, flatulence, increased exhaust and diarrhea, and the incidence was 61% (49/80), 8% (6/80), 5% (4/80) and 4% (3/80), respectively, and 16% (13/80) of the patients had prolonged occasional mild dysphagia. There was no death, symptomatic recurrence or reoperation. Conclusions: The novel W-H fundoplication has a good medium-term efficacy, with significant GERD symptom control rate and PPI discontinuation rate. The postoperative dysphagia is common, but it is self-limiting and does not affect the satisfaction of the surgical effect.

Abstract
Objective: To analysis the income and expenditure of HIV-positive pregnant women and the catastrophic health expenditure of their households in high AIDS endemic areas in Liangshan prefecture. Methods: From December 2018 to January 2019, a total of 250 pregnant women were recruited from 2 of 17 counties in Liangshan Prefecture, including 133 HIV-positive pregnant women and 117 HIV-negative pregnant women. The data, including basic information of pregnant women, basic information of the family, annual family income in 2017, annual family health expenditure in 2017, and maternal and child-related expenditure in 2017, were collected for analyzing the incidence of catastrophic health expenditure in the family. Results: The average annual income and average annual health expenditure of HIV-positive pregnant women households were 7 000 CNY and 2 000 CNY, while those of HIV-negative pregnant women households were 10 000 CNY and 3 000 CNY, respectively. Based on the criteria of 15%, 25% and 40%, the incidence of catastrophic health expenditure of HIV-positive pregnant households was 39.10%, 33.83% and 27.82%, with average differences of 34.84%, 31.17% and 26.65%, respectively, while that of HIV-negative pregnant women households was 38.46%, 33.33% and 23.93%, with average differences of 31.68%, 28.35% and 24.22%, respectively. Conclusion: The incidence of catastrophic health expenditure of pregnant households in high AIDS endemic areas in Liangshan prefecture is high. The incidence of HIV-positive families is slightly higher than that of HIV-negative families. We suggest that medical insurance compensation in Liangshan prefecture should be improved to reduce the impact of catastrophic health expenditure.

Abstract
To investigate the effects of dietary taurine supplementation on growth performance, antioxidant status, and lipid metabolism in broilers, 384 male broilers (Arbor Acres, 1 D of age) were randomly allocated into 4 groups with 8 replicates of 8 birds. Dietary treatments were supplemented with taurine at the level of 0.00, 2.50, 5.00, and 7.50 g/kg of the diet (denoted as CON, TAU1, TAU2, TAU3, respectively). The BW gain from 1 to 21 D and from 22 to 42 D were all increased linearly (linear, P < 0.001) by taurine supplementation. Throughout the trial period, the highest BW gain and favorable gain-to-feed ratio were observed in the TAU2 group. Taurine supplementation increased the antioxidant enzyme activities and decreased (linear, P < 0.001) the content of malondialdehyde in both serum and the liver of broilers and alleviated oxidative damage through enhancing (P < 0.05) the hepatic genes expression of nuclear factor erythroid-2-related factor 2 (NRF2), glutathione peroxidase (GPX), and heme oxygenase-1 (HO-1). Correspondingly, in serum, the activities of hepatic lipase and total lipase were decreased linearly and quadratically (linear and quadratic, P < 0.001) with the increasing inclusion of taurine in the diet. Meanwhile, in serum, the content of triglycerides was significantly decreased (P < 0.05), and except for TAU3, the total cholesterol content was also significantly decreased (P < 0.05) by taurine supplementation. In addition, the hepatic content of triglycerides was significantly decreased (P < 0.05) in the TAU1 and TAU2 groups. Compared with the CON group, the hepatic genes expression of adenosine monophosphate-activated protein kinase alpha (AMPKα), silent 1, (SIRT1) and carnitine palmitoyltransferase 1 (CPT-1) were all increased (P < 0.05), and sterol regulatory element-binding protein-1 (SREBP-1) expression was decreased (P < 0.05) in the TAU2 group. These results indicated that taurine supplementation improved the growth performance, antioxidant capacity, and lipid metabolism of broilers.

Abstract
OBJECTIVE To evaluate the clinical efficacy of total knee arthroplasty (TKA) in the treatment of primary osteoarthritis (OA) and osteoarthritis of Kashin-Beck disease (KBD). METHODS This study enrolled 77 KBD patients (77 knees, KBD-TKA) and 75 OA patients (75 knees, OA-TKA) who underwent TKA from September 2008 to June 2018. Clinical assessments for each patient were performed pre-operatively and last follow-up. The efficacy measures included the visual analogue scale (VAS) pain score, range of motion (ROM), Hospital for Special Surgery (HSS) score, and short form 36 Health Survey (SF-36) as well as related influencing factors between the two groups. RESULTS All patients were followed up; the follow-up time of KBD-TKA was 14-132 months, with an average of 72.68 ± 37.55 months; OA-TKA was 15-120 months, with an average of 49.2 ± 28.91 months. There was no difference in pre-operative VAS score (7.29 vs. 7.24) and SF-36 (PCS) score (4.87 vs. 5.49) between KBD-TKA and OA-TKA (P > 0.05), while compared with OA, KBD-TKA had significantly worse pre-operative ROM (75.48° vs. 82.87°), HSS score (36.40 vs. 41.84), and SF-36 (MCS) score (26.28 vs. 28.73) (P < 0.05). At the final follow-up, there was no significant difference in VAS score (1.13 vs. 1.16), ROM (105.79 vs. 105.79), and HSS score (92.06 vs. 92.25) between KBD-TKA and OA-TKA (P > 0.05), while compared with OA, KBD-TKA had significantly worse SF-36 (PCS) score (36.90 vs. 42.00) and SF-36 (MCS) score (55.16 vs. 59.70) (P < 0.05). In a multivariate regression, controlling for multiple potential confounders, diagnosis of KBD was associated with poor quality of life after surgery, whereas pre-operative pain was specifically associated with post-operative pain. However, preoperative gender, age, BMI, and the angles of knee prosthesis (before and after surgery) were not associated with post-operative outcome. CONCLUSION Patients with KBD undergoing primary TKA have excellent outcomes, comparable with OA at the final follow-up, in spite of worse pre-operative ROM, HSS score, and SF-36(MCS) score. However, KBD patients are worse than OA in terms of general health. Pre-operative age, gender, BMI, and the angles of knee prosthesis were not the factors influencing the clinical efficacy of TKA. The diagnosis of KBD was an independent risk factor for poor quality of life after TKA. Pre-operative pain was a clinically important predictor of outcome.

Abstract
Objective: To analyze the relationship between the severity of esophageal acid reflux and esophageal motility, esophageal mucosal injury and morphological anatomy of gastroesophageal junction (GEJ) in patients with gastroesophageal reflux disease (GERD). Methods: The clinicaldata of GERD patients who underwent 24 h pH-impedance monitoring, gastroscopy and high-resolution manometry (HRM) from January 2016 to January 2019 in the Gastroesophageal Surgery Department of PLA Rocket Force Characteristic Medical Center were retrospectively analyzed. The patients were divided into non-pathological acid reflux group, mild pathological acid reflux group and moderate to severe pathological acid reflux group according to the DeMeester score. The gender and age of each group were matched, with 60 cases in each group. Statistical analysiswas performed to analyze thedifferences in upper esophageal sphincter pressure, lower esophageal sphincter pressure (LES), LES length, length of ventral LES, percentage of ineffective swallowing, esophagitis, Hill grade of GEJ, and hiatus hernia (HH) in each group. The comparison and correlation analysis are also carried out between the groups. Results: The male-female ratio was 33/27, and the age was (57±13) years in each group. Non-parametric analysis showed that the LES pressure and the length of the ventral LES decreased with the severity of acid reflux, and there was a statistical difference (P= 0.033, P=0.015). The detection rate of HH by HRM increased significantly (χ(2)=0.001) as well. Esophagitis score increased with the severity of acid reflux and there was statistical difference (P<0.001).The detection rate of esophagitis increased significantly (χ(2)<0.001) as well. Hill grading score of GEJ increased with the severity of acid reflux, and there was statistical difference (P<0.001).The detection rate of HH by endoscopy increased significantly (χ(2)<0.001) as well. The correlation between DeMeester score and LES pressure, length of ventral LES, percentage of ineffective swallowing, esophagitis score, and Hill grade score were statistically significant (P<0.05). Conclusions: The esophageal low motility (such as low LES pressure) and anatomical abnormalities (abdominal esophageal shortening, GEJ flabbiness, and even HH formation) of the GEJ regionare significantly associated with the severity of acid reflux. These factors may be important causes of increased acid reflux. In addition, the aggravation of acid reflux can also increase the incidence and severity of esophagitis.

Abstract
Objective: To explore the relationship between liver controlled attenuation parameters (CAP) and body fat mass and its distribution. Methods: From May to December 2018, 978 adult patients visited at the fatty liver center of the Third People's Hospital of Changzhou were treated. The patient's liver controlled attenuation parameters were measured by transient elastography and the body fat mass and its distribution were measured by bioelectrical impedance technology. Pearson's correlation coefficient was adopted to describe the correlation between liver CAP value and body mass index (BMI), body fat mass index (BFMI), trunk fat mass index (TFMI), limbs fat mass index (LFMI) and visceral fat area (VFA). Receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate BMI, BFMI, TFMI, LFMI and VFA to differentiate the cut-off points and efficacy of CAP for diagnosing grading of fatty liver changes in S0-1 and S2-3. Results: In 653 cases of male, S0 ~ S3 accounted for 4.90%, 3.37%, 22.36% and 69.37%, respectively, and in 325 cases of females, S0 ~ S3 accounted for 7.38%, 6.46%, 13.23% and 72.92%, respectively. Female patients had more visceral, trunk and limbs fat than male (P < 0.01). Body mass, body fat mass, body fat percentage, BMI, BFMI, TFMI, LFMI, and VFA were increased in male and female patients with increasing liver fat grade (P < 0.01). CAP values of male and female patients were positively correlated with BMI, BFMI, TFMI, LFMI and VFA. Percentage of body fat mass increased with increasing liver fat grade (male: F = 13.42, P < 0.001; female: F = 3.22, P = 0.023); while limb fat mass percentage did not increase with liver fat grade (Male: F = 1.13, P = 0.34; female: F = 1.05, P = 0.37). Hepatic steatosis grading (S0 ~ 1 or S2 ~ 3) diagnosed with CAP were distinguished through BMI, BFMI, TFMI, LFMI and VFA. AUC was 0.80 ~ 0.82 in males (P < 0.01), and 0.75 ~ 0.78 in females (P < 0.01). Conclusion: The liver CAP value is positively correlated with the body's limbs, trunk and visceral fat, and has a strong correlation with trunk and visceral fat. BMI, BFMI, TFMI, LFMI and VFA up to some extent can identify the CAP diagnosis of grading of fatty liver changes in S0-1 and S2-3.

Abstract
Objective: To evaluate the incidence of intraoperative vascular injury (IVI) and associated anatomical features during laparoscopy - assisted distal gastrectomy (LADG) with D2 lymphadenectomy for gastric cancer. Methods: A descriptive cohort study was performed. Clinical data and operational videos of 278 consecutive gastric cancer patients who underwent LADG with D2 lymphadenectomy for gastric cancer at Department of General Surgery of Nanfang Hospital between January 2010 and December 2017 were retrospectively analyzed. IVI and vascular anatomy during lymphadenectomy were observed and recorded in the following four scenes: scene I: No. 4sb and No.4d of lower left (tail of pancreas) area; scene II: No.6 of lower right (subpyloric) area; scene III: No.5 and No.12a of upper right (suprapyloric) area; scene IV: No. 7, No. 8a, No. 9, No. 11p of central area posterior to the gastric body. IVI was defined as the injury of main perigastric vessel requiring additional procedure for hemostasis such as electrocauterization, gauze compression, clipping or suture. Results: Among 278 patients, 125 (45.0%) had IVI. Two cases of IVI required conversion to open operation and the injuried vascular was left gastric artery (LGA) and right gastric artery (RGA), respectively. Higher incidence of IVI was found in scene II (92/278, 33.1%) and scene IV(39/278, 14.0%). More common IVI was observed in right gastroepiploic vein (RGeV, 57/278, 20.5%) and left gastric vein (LGV, 33/278, 11.9%). The right gastroepiploic vessels were observed in all 278 patients, including 3 (1.1%) cases with 2 RGeVs, and 2 cases with 2 right gastroepiploic arteries (RGeA). RGA was observed clearly in 265 (95.3%) patients, whose ramification pattern was as follows: from proper hepatic artery (PHA, 223/265, 84.2%), from gastroduodenal artery (GDA, 16/265, 6.0%), from left hepatic artery (LHA, 12/265,4.5%), from the crossing of PHA and GDA (8/265, 3.0%), and 6 (2.3%) patients with 2 RGAs simultaneously from PHA and GDA, respectively. The most common injury of RGA (4/12) occurred in LHA. Excluding 2 cases of conversion to open surgery due to intraoperative hemorrhage, among 276 patients, LGV was observed in 270 patients (97.1%), whose drainage pattern was as follows: into the portal vein (PV, 148/270, 54.8%), into the spleen vein (SV, 56/270, 20.7%), into the junction of these two veins (52/270, 19.3%), into left portal vein (LPV, 8/270, 3.0%), meanwhile 6 patients had 2 LGVs simultaneously, including LGVs of 5 cases into PV and SV, and of 1 case into PV-SV junction and SV. The most common IVI was found in those patients with two LGVs (4/6). Conclusions: IVI during LADG with D2 lymphadenectomy is common. The highest risk of IVI is found in scene II and scene IV. Attentions should be paid to anatomic variation of vessels, especially the RGeV, LGV and RGA.

Abstract
Objective: To analyze esophageal motility dysfunction in gastroesophageal reflux disease (GERD) with different severity of esophagitis, and the relationship between the esophageal motility dysfunction and the severity of esophagitis. Methods: GERD patients simultaneously undergone endoscopy and high-resolution manometry were divided into four groups: Non-esophagitis (Non-erosive gastroesophageal reflux disease, NERD) group, mild esophagitis group, moderate esophagitis group and severe esophagitis group. The gender and age were matched for each group, and every group consisted of 80 cases. Nonparametric test was used to analyze the differences in HRM parameters, such as upper esophageal sphincter (UES) pressure, lower esophageal sphincter (LES) pressure, LES length, LES-CD (crural diaphragm) separation distance, and the percentage of failed peristalsis of the four groups, and the differences between each two of the groups were also analyzed. Results: Nonparametric test showed that the LES pressure and length decreased with the severity of esophagitis, and there were statistical differences (P<0.001, P=0.030). The failed peristalsis percentage increased with the severity of esophagitis and the difference was statistically significant (P<0.001). The LES-CD separation distance was increased with the severity of esophagitis and had statistically significance (P<0.001). When comparing the differences between each two of the groups, there were significant differences (P<0.001, P=0.012, P<0.001, P<0.001) between NERD group and severe esophagitis group in the HRM parameters of the lower esophageal sphincter pressure, the LES length, the LES-CD separation distance, and the percentage of ineffective swallowing in the NERD and severe esophagitis group. The detection rate of HH was significantly increased from NERD to severe esophagitis, the detection rate of HH was 6.3% to 82.5% in gastoracopy and 16.3% to 45.0% in HRM, and the diagnostic consistency was fair (Kappa Value: 0.31). Conclusions: Hypo-dynamic state of esophageal and HH are the main motility characteristics of erosive gastroesophageal reflux disease, Esophageal motility abnormalities increase in parallel with the severity of GERD from NERD to severe esophagitis, these motility disorders may also play important roles in causing esophagitis.

Abstract
BACKGROUND AND AIM Determining individual risk of short-term mortality in patients with acute-on-chronic hepatitis B liver failure (ACHBLF) is a difficult task. We aimed to develop and externally validate a prognostic nomogram for ACHBLF patients. METHODS The nomogram was built to estimate the probability of 30-day, 60-day, 90-day, and 60-month survival based on an internal cohort of 246 patients with ACHBLF. The predictive accuracy and discriminative ability of nomogram were determined by a concordance index (C-index), calibration curve, and time-dependent receiver operating characteristics (tdROC), comparing with model for end-stage liver disease (MELD) score. The results were validated using bootstrap resampling and an external cohort of 138 patients. Furthermore, we plotted decision curves to evaluate the clinical usefulness of nomogram. RESULTS Independent factors derived from multivariable Cox analysis of training cohort to predict mortality were age, total bilirubin, serum sodium, and prothrombin activity, which were all assembled into nomogram. The calibration curves for probability of survival showed optimal agreement between nomogram prediction and actual observation. The C-index of nomogram was higher than that of MELD score for predicting survival (30-day, 0.809 vs 0.717, P < 0.001; 60-day, 0.792 vs 0.685, P < 0.001; 90-day, 0.779 vs 0.678, P < 0.001; 6-month, 0.781 vs 0.677, P < 0.001). Additionally, tdROC and decision curves also showed that nomogram was superior to MELD score. The results were confirmed in validation cohort. CONCLUSIONS The prognostic nomogram provided an individualized risk estimate of short-term survival in patients with ACHBLF, offering to clinicians to improve their abilities to assess patient prognosis.

Abstract
The xantha marker trait, which is controlled by a down-regulating epi-mutation of OsGUN4, has been applied to the production of hybrid rice. However, the molecular basis for the ability of xantha mutants to attain high photosynthetic capacity even with decreased chlorophyll contents has not been characterized. In the present study, we observed that the total chlorophyll content of the xantha mutant was only 27.2% of that of the wild-type (WT) plants. However, the xantha mutant still accumulated 59.9% of the WT δ-aminolevulinic acid content, 72.8% of the WT Mg-protoporphyrin IX content, and 63.0% of the WT protochlorophyllide a content. Additionally, the protoporphyrin IX and heme contents in the mutant increased to 155.0 and 160.0%, respectively, of the WT levels. A search for homologs resulted in the identification of 124 rice genes involved in tetrapyrrole biosynthesis and photosynthesis. With the exception of OsGUN4, OsHO-1, and OsHO-2, the expression levels of the genes involved in tetrapyrrole biosynthesis were significantly higher in the xantha mutant than in the WT plants, as were all 72 photosynthesis-associated nuclear genes. In contrast, there were no differences between the xantha mutant and WT plants regarding the expression of all 22 photosynthesis-associated chloroplast genes. Furthermore, the abundance of 1O2 and the expression levels of 1O2-related genes were lower in the xantha mutant than in the WT plants, indicating 1O2-mediated retrograde signaling was repressed in the mutant plants. These results suggested that the abundance of protoporphyrin IX used for chlorophyll synthesis decreased in the mutant, which ultimately decreased the amount of chlorophyll in the xantha mutant. Additionally, the up-regulated expression of photosynthesis-associated nuclear genes enabled the mutant to attain a high photosynthetic capacity. Our findings confirm that OsGUN4 plays an important role in tetrapyrrole biosynthesis and photosynthesis in rice. GUN4, chlorophyll synthesis pathways, and photosynthetic activities are highly conserved in plants and hence, novel traits (e.g., xantha marker trait) may be generated in other cereal crops by modifying the GUN4 gene.

Abstract
OBJECTIVE To investigate the safety and effectiveness of laparoscopic reoperation for patients with gastroesophageal reflux disease (GERD) recurred form previous anti-reflux surgery. METHODS Totally 19 patients received laparoscopic reoperation for symptomatic and anatomic recurred GERD in Department of Gastroesophageal Reflux Disease, Rocket Force General Hospital from January 2008 to September 2015 were retrospectively analyzed. There were 12 male and 7 female patients. The average reoperation age was (48±14) years, the average duration of reoperation from original ones was (43±38) months. The patients underwent preoperative barium, endoscopy, manometry and 24-hour pH studies. Laparoscopic hiatal hernia repair plus fundoplication was carried out for reoperation. Gastroesophageal reflux related symptoms (reflux, heartburn, chest pain, chough, wheezing, chest tightness and globus sensation) before and after surgery were compared by a questionnaire. The patients' medication consumption, complications and satisfaction of the reoperation were investigated as well. The repeated measures analysis of variance was used for statistical comparison of data preoperatively and postoperatively. RESULTS No major complication and death occurred. Six cases (32%) had complications such as diarrhea, increased passing wind, flatulence, dysphagia and abdominal pain. The GERD related symptom score of reflux, heartburn, chest pain, chough, wheezing, chest tightness and globus sensation all significantly decreased (F: 25.0 to 56.7; P: 0.000 to 0.001) after the reoperation, with 68% good outcome of all the patients. After a follow-up of (33±22) months after reoperation, 1 case had partial recurrence at the 3(rd) month after reoperation. For all the patients, 12 cases felt very satisfied or satisfied with the reoperation. CONCLUSION Laparoscopic reoperation is generally effective with acceptable morbidity rates for patients with esophageal and extraesophageal symptoms recurred form previous hiatal repair and (or) fundoplication.

Abstract
OBJECTIVE To investigate the condition of isoprenaline (ISO)-induced cardiac hypertrophy in the FVB/N mouse. METHODS ISO (30 mg/kg/d) was administered either by daily subcutaneous injection, or by continuous infusion via an implanted osmotic minipump. The mice in each mode of administration were randomly divided into two groups. For subcutaneous injection: the mice received ISO or saline through daily subcutaneous injection for 2 weeks. The mice for minipump: the mice received continuous infusion of ISO via an implanted osmotic minipump for 2 weeks, or received sham operation as the control to mimipump. The ratio of heart weight to tibia length (HW/TI), the diastolic left ventricular posterior wall thickness (dLVPW) were used to indicate cardiac hypertrophy. Interstitial fibrosis was examined with picrosirius red staining. RESULTS ISO (30 mg/kg/d) administered by daily subcutaneous injection did not lead to cardiac hypertrophy or fibrosis in the FVB/N mice, and 50% of the mice died before the end point. The mice receiving ISO via minipumps showed significant increase in HW/TI [(10.60±0.40 ) mg/mm vs. (7.93±0.19) mg/mm,P<0.001] and dLVPW [(0.87±0.03) mm vs. (0.68±0.06)mm,P=0.0116]. ISO administered via minipumps did not induce cardiac fibrosis. All the mice in this group survived to the end point. CONCLUSION ISO (30 mg/kg/d) administered by continuous infusion via a minipump for 2 weeks can lead to significant cardiac hypertrophy.

Abstract
AIM The aim of the present study was to prospectively evaluate the Stretta radiofrequency (RF) treatment for gastroesophageal reflux disease (GERD) -related respiratory symptoms over a 5-years follow-up period. METHODS A total of 132 patients underwent the Stretta procedure between April 2007 and February 2009; 122 of the patients (92.4%) completed the 5-year follow-up. Symptom scores and PPI usage were evaluated at baseline, 6 months, 1 year, 3 years and 5 years after treatment. RESULTS A total of 122 patients (age, 51.7 ± 13.0 years, M:F, 52: 70) were followed up for 5 years and their outcomes were analyzed. At 5 years after treatment, the symptom scores were significantly reduced (heartburn score, from 5.67 ± 1.52 to 2.41 ± 1.13; regurgitation score, from 5.43 ± 1.66 to 2.27 ± 1.33; chest pain score, from 4.45 ± 1.47 to 2.40 ± 0.88; cough score, from 6.62 ± 1.73 to 3.14 ± 1.43; and asthma score, from 6.83 ± 1.46 to 3.26 ± 1.53, P<0.001). Moreover, 56.6% of the patients were completely off PPIs. CONCLUSION Stretta RF significantly improves the symptoms and reduces PPI usage at 5 years. Therefore, it is a viable, effective, and minimally invasive endoluminal procedure for patients with GERD-related respiratory symptoms.

Abstract
AIM Chronic cough is the most common extra-esophageal manifestation of gastroesophageal reflux disease (GERD). This study aimed to retrospectively analyze outcomes in patients with GERD-related cough following laparoscopic Nissen fundoplication (LNF) and Stretta radiofrequency (RF) respectively. METHODS Medical charts of 83 patients with GERD-related cough that underwent LNF or Stretta RF between 2007 and 2012 were retrieved. Symptom scores (heartburn, regurgitation and cough) and proton pump inhibitors (PPIs) usages were evaluated. RESULTS A total of 83 patients with GERD-related cough underwent LNF (N.=35) and Stretta RF (N.=48), and were followed up 36.78 ± 16.12 months (range 13-55 months). During the follow-up, the post-treatment scores were statistically lower as compared with the pre-treatment scores in both groups, while the cough improvement after Stretta was significantly lower than that after LNF (P<0.001). Besides, 27 (77.1%) patients achieved complete PPI therapy independence after LNF, comparing with 27 (65.1%) after Stretta (P<0.05). No significant differences in post-treatment complications were observed except for the abdominal distention. CONCLUSION Even though laparoscopic Nissen fundoplication and Stretta are capable of controlling GERD-related cough effectively and safely in selected patients, laparoscopic Nissen fundoplication could improve more in symptoms and PPI elimination.

Abstract
BACKGROUND AND AIM Controlled attenuation parameter (CAP) is a novel ultrasound-based elastography method for detection of steatosis severity. This meta-analysis aimed to assess the performance of CAP. METHODS PubMed, the Cochrane Library, and the Web of Knowledge were searched to find studies, published in English, relating to accuracy evaluations of CAP for detecting stage 1 (S1), stage 2 (S2), or stage 3 (S3) hepatic steatosis which was diagnosed by liver biopsy. Sensitivities, specificities, and hierarchical summary receiver operating characteristic (HSROC) curves were used to examine CAP performance. The clinical utility of CAP was also evaluated. RESULTS Nine studies, with 11 cohorts were analyzed. The summary sensitivities and specificities values were 0.78 (95% confidence interval [CI], 0.69-0.84) and 0.79 (95% CI, 0.68-0.86) for ≥ S1, 0.85 (95% CI, 0.74-0.92) and 0.79 (95% CI, 0.71-0.85) for ≥ S2, and 0.83 (95% CI, 0.76-0.89) and 0.79 (95% CI, 0.68-0.87) for ≥ S3. The HSROCs were 0.85 (95% CI, 0.81-88) for ≥ S1, 0.88 (95% CI, 0.85-0.91) for ≥ S2, and 0.87 (95% CI, 0.84-0.90) for ≥ S3. Following a "positive" measurement (over the threshold value) for ≥ S1, ≥ S2, and ≥ S3, the corresponding post-test probabilities for the presence of steatosis (pretest probability was 50%) were 78%, 80% and 80%, respectively; if the values were below these thresholds ("negative" results), the post-test probabilities were 22%, 16%, and 17%, respectively. CONCLUSIONS CAP has good sensitivity and specificity for detecting hepatic steatosis; however, based on a meta-analysis, CAP was limited in their accuracy of steatosis, which precluded widespread use in clinical practice.

Abstract
Toxoplasma gondii can infect a wide variety of warm-blooded animals, including bats. Limited information on T. gondii infection in bats is available in China. The objective of the present study was to determine prevalence and genetic diversity of T. gondii infection in bats in southern China. A total of 608 bats representing 12 species, including 120 Aselliscus stoliczkanus, 59 Myotis chinensis, 11 Miniopterus schreibersii, 53 Rhinolophus affinis, 32 Rhinolophus pusillus, 81 Hipposideros armiger, 28 Hipposideros fulvus, 32 Cynopterus brachyotis, 14 Cynopterus sphinx, 45 Eonycteris spelaea, 109 Hipposideros larvatus, and 24 Taphozous melanopogon, were collected from Yunnan and Guangxi provinces, southern China. They were examined for the presence of T. gondii DNA by amplification of the B1 gene using a nested PCR, and the positive samples were genotyped at 11 genetic loci (SAG1, 5'- and 3'-SAG2, alternative SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 and Apico) using multilocus polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technology. Fifty-nine (9.7%) of these bats were detected positive by PCR but only five of these positive DNA samples were completely typed at all loci; of which 4 samples, 2 from A. stoliczkanus, and 2 from H. larvatus, belonged to ToxoDB Genotype #10, and the other one from H. larvatus was identified as ToxoDB Genotype #9 (http://toxodb.org/toxo/). To our knowledge, this is the first report of molecular detection and genetic characterization of T. gondii infection in bats in China. The results show that these bats are potential reservoirs for T. gondii transmission, which may pose a threat to human health.

Abstract
Cyclin-dependent kinase 4 (CDK4) is known to be a 33 kD protein that drives G 1 phase progression of the cell cycle by binding to a CCND protein to phosphorylate RB proteins. Using different CDK4 antibodies in western blot, we detected 2 groups of proteins around 40 and 33 kD, respectively, in human and mouse cells; each group often appeared as a duplet or triplet of bands. Some CDK4 shRNAs could decrease the 33 kD wild-type (wt) CDK4 but increase some 40 kD proteins, whereas some other shRNAs had the opposite effects. Liquid chromatography-mass spectrometry/mass spectrometry analysis confirmed the existence of CDK4 isoforms smaller than 33 kD but failed to identify CDK4 at 40 kD. We cloned one CDK4 mRNA variant that lacks exon 2 and encodes a 26 kD protein without the first 74 amino acids of the wt CDK4, thus lacking the ATP binding sequence and the PISTVRE domain required for binding to CCND. Co-IP assay confirmed that this ΔE2 protein lost CCND1- and RB1-binding ability. Moreover, we found, surprisingly, that the wt CDK4 and the ΔE2 could inhibit G 1-S progression, accelerate S-G 2/M progression, and enhance or delay apoptosis in a cell line-specific manner in a situation where the cells were treated with a CDK4 inhibitor or the cells were serum-starved and then replenished. Hence, CDK4 seems to be expressed as multiple proteins that react differently to different CDK4 antibodies, respond differently to different shRNAs, and, in some situations, have previously unrecognized functions at the S-G 2/M phases of the cell cycle via mechanisms independent of binding to CCND and RB.

Abstract
This paper is to report the polymorphism of raw materials of clopidogrel bisulfate at home and abroad. By the analysis of Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (p-XRD), samples are roughly classified into two groups, except one patent material. And the differential scanning calorimeter (DSC) examination showed more detailed information for these materials. The results of the study could provide comprehensive basis for the quality evaluation of clopidogrel bisulfate.

Abstract
Mining the disease information contained in the low-molecular-weight range of a proteomic profile is becoming of increasing interest in cancer research. This work evaluates the ability of nanoporous silicon microparticles (NPSMPs) to capture, enrich, protect, and detect low-molecular-weight peptides (LMWPs) sieved from a pool of highly abundant plasma proteins. The average pore size and porosity of NPSMPs are controlled by the electrochemical preparation conditions, and the critical parameters for admission or exclusion of protein with a definite molecular weight are determined by reflectometric-interference Fourier transform spectroscopy (RIFTS). Sodium dodecyl sulfate polyacrylamide-gel electrophoresis (SDS-PAGE) and matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) analysis of the proteins captured by the NPSMPs show that the chemical nature of the NPSMPs surface and the solution pH also play vital roles in determining the affinity of NPSMPs for target analytes. It is found that carboxyl-terminated porous microparticles with a porosity of 26% (pore diameter around 9.0 nm) specifically fractionate, enrich and protect LMWPs sieved from either simulated samples or human serum samples. Moreover, NPSMPs containing captured peptides can be directly spotted onto a MALDI plate. When placed in a conventional MALDI matrix, laser irradiation of the particles results in the release of the target peptides confined in the nanopores, which are then ionized and detected in the MALDI experiment. As a proof-of-principle test case, mass spectra of NPSMPs prepared using serum from colorectal cancer patients and from control patients can be clearly distinguished by statistical analysis. The work demonstrates the utility of the method for discovery of biomarkers in the untapped LMWP fraction of human serum, which can be of significant value in the early diagnosis and management of diseases.

Abstract
Fruit lycopene content and total soluble solid content are important factors determining fruit quality of tomatoes; however, the dynamic quantitative trait loci (QTL) controlling lycopene and soluble solid content have not been well studied. We mapped the chromosomal regions controlling these traits in different periods in F(2:3) families derived from a cross between the domestic and wild tomato species Solanum lycopersicum and S. pimpinellifolium. Fifteen QTLs for lycopene and soluble solid content and other related traits analyzed at three different fruit ripening stages were detected with a composite interval mapping method. These QTLs explained 7-33% of the individual phenotypic variation. QTLs detected in the color-changing period were different from those detected in the other two periods. On chromosome 1, the soluble solid content QTL was located in the same region during the color-changing and full-ripe periods. On chromosome 4, the same QTL for lycopene content was found during the color-changing and full-ripe periods. The QTL for lycopene content on chromosome 4 co-located with the QTL for soluble solid content during the full-ripe period. Co-location of lycopene content QTL and soluble solid content QTLs may be due to pleiotropic effects of a single gene or a cluster of genes via physiological relationships among traits. On chromosome 9, the same two QTLs for lycopene content at two different fruit ripening periods may reflect genes controlling lycopene content that are always expressed in tomato fruit development.

Abstract
In July 2011, bacterial stripe was observed on a commercial field of hog millet (Panicum miliaceum L.) in Chuncheon, Korea, with a disease incidence of 37% in the field. Symptoms on leaves included reddish-brown, long, narrow stripes that varied in length and were sharply delineated by uninfected adjacent vascular bundles. Eleven bacterial isolates (BC3107, BC3214 to BC3223) were recovered on trypticase soy agar from lesions surface sterilized in 70% ethanol for 1 min. The isolates, all obtained from different plants, were gram negative, oxidase positive, aerobic rods with two to four flagella. The isolates produced circular, cream-colored, nonfluorescent, butyrous colonies with entire margins on King's B medium. Using the Biolog Microbial Identification System, Version 4.2 (Biolog Inc., Hayward, CA), the isolates were identified as Acidovorax avenae subsp. avenae with Biolog similarity indices ranging from 0.52 to 0.72 after 24 hr. Characters for differentiating between Acidovorax spp. were tested according to Schaad et al. (2). The isolates were positive for gelatin liquefaction, nitrate reduction, lipase production, utilization of D-mannitol, sodium citrate, and alkaline in litmus milk. The isolates were negative for utilization of D-arabitol and did not amplify with PCR primer sets Aaaf5, Aaaf3/Aaar2, and Aacf2/Aacr2. Colonies were V-, V+, and V+ for utilization of D-fucose, maltose, and ethanol, respectively. Regions of the 16S rRNA (rrs) and the IGS were sequenced to aid in the identification of the isolates using reported PCR primer sets (1,4). A 1,426 bp fragment of the rrs region shared 100% similarity with all strains of A. avenae available in GenBank. Pathogenicity tests were separately performed for the 11 isolates in different greenhouses located in Suwon (National Academy of Agricultural Science), and Chuncheon (Gangwondo Agricultural Research and Extension Services) in Korea. Pathogenicity was confirmed by clip inoculation with sterilized scissors dipped into cell suspensions containing 105 CFU/ml on three 8-day-old leaves of hog millet (two plants per isolate), rice (Oryza sativa L. cv. Hopyeong), and sweet corn (Zea mays L. cv. Daehak) in a greenhouse maintained at 28 to 32°C and 90% relative humidity. The isolates induced similar symptoms as those originally observed on hog millet 5 days after inoculation. No symptoms were observed on the control plants (hog millet, rice, and sweet corn), which were clipped with scissors dipped in sterilized distilled water. The identity of bacteria reisolated from the stripes on inoculated leaves was confirmed by analyzing sequences of the 16S-23S rRNA intergenic spacer region (IGS) (1). On the basis of physiological, pathological, and sequence data, the isolates were identified as A. avenae subsp. avenae. To our knowledge, this is the first report of bacterial stripe of hog millet caused by A. avenae subsp. avenae in Korea. The spread of the bacterial disease is expected to have a significant economic impact on hog millet culture in the fields of Gangwon Province in Korea. Nucleotide sequence data reported are available under accession numbers JQ743877 to JQ743887 for rrs of BC 3207 and BC3214 to BC3223, and JQ743877 to JQ743887 for IGS of BC3207 and BC3214 to BC3223.

Abstract
In September 2011, bacterial leaf spot was observed on zinnia plants (Zinnia elegans L.) grown in a garden in Suwon, Korea. Leaf symptoms included angular lesions that were yellow or brown-to-reddish brown in the center. Bacterial isolates (BC3293 to BC3299) were recovered on trypticase soy agar from lesions surface-sterilized in 70% ethyl alcohol for 1 min. Pathogenicity of the isolates was confirmed by spray inoculation with a bacterial suspension (106 CFU/ml) prepared in sterile distilled water and applied to zinnia plants at the four- to five-leaf growth stage (two plants per isolate). Sterile distilled water was used as the negative control. The inoculated plants were incubated in a greenhouse at 26 to 30°C and 95% relative humidity. Characteristic leaf spot symptoms developed on inoculated zinnia plants 5 days after inoculation. No symptoms were observed on the negative control plants. The bacterium reisolated from the inoculated leaves was confirmed through gyrB gene sequence analysis (3). All isolates were gram-negative, aerobic rods, each with a single flagellum. Isolates were positive for catalase and negative for oxidase. The biochemical and physiological tests for differentiation of Xanthomonas were performed using methods described by Shaad et al. (2). The isolates were positive for mucoid growth on yeast extract-dextrose-calcium carbonate agar, growth at 35°C, hydrolysis of starch and esculin, protein digestion, acid production from arabitol, and utilization of glycerol and melibiose. Colonies were negative for ice nucleation, and alkaline in litmus milk. The gyrB gene (870 bp) and the 16S-23S rRNA internal transcribed spacer (ITS) regions (884 bp) were sequenced to aid in identification of the original field isolates using published PCR primer sets Xgyr1BF/Xgyr1BR (3) and A1/B1 (1), respectively. Sequence of the gyrB gene (GenBank Accession Nos. JQ665732 to JQ665738) from the zinnia field isolates shared 100% sequence identity with the reference strain of Xanthomonas campestris pv. zinniae (GenBank Accession No. EU285210), and the ITS sequences (GenBank Accession Nos. JQ665725 to JQ665731) had 99.9% sequence identity with X. campestris pv. zinnia XCZ-1 (GenBank Accession No. EF514223). On the basis of the pathogenicity assays, biochemical and physiological tests, and sequence analyses, the isolates were identified as X. campestris pv. zinniae. To our knowledge, this is the first report of bacterial leaf spot of zinnia caused by X. campestris pv. zinniae in Korea. The disease is expected to result in economic and aesthetic losses to plants in Korean landscapes. Thus, seed treatment with bactericides will be required to control the bacterial leaf spot of zinnia before planting. References: (1) T. Barry et al. The PCR Methods Appl. 1:51, 1991. (2) N. W.

Abstract
The microstructure and magnetic properties of multilayer [Os(t)/FePt(x)]n films on a glass substrate with a 10 nm Os buffer layer by ion beam sputtering have been studied as a function of the annealing temperatures between 300 and 800 degrees C. Here, t = 0.2, 1 or 5 nm and x varied from 10, 20, 25, 50, to 100 nm with its associated n value of 10, 5, 4, 2, and 1, respectively. No diffusion evidence was found in samples with a thin Os layer and t > or = 1 nm. The average grain size of the multilayer films can be well controlled by both annealing temperature and thickness of the FePt layer by a very thin Os space layer with t > or = 1 nm. The enhancement of H(c) can be understood from the fact that for a FePt film with an Os spacer layers, the increasing number of Os layer will inhibit the grain growth of FePt grains and enriches the grain boundary. We have experimentally demonstrated that even with a very thin 1 nm Os spacer layers, the [Os(t)/FePt(x)]n multilayer films can exhibit good hard magnetic properties and are attractive candidates for ultrahigh density magnetic recording media.

Abstract
BRM is an ATPase component of the SWI/SNF complex that regulates chromatin remodeling and cell proliferation and is considered a tumor suppressor. In this study we characterized transcripts from the Smarca2 gene that encodes the BRM protein. We found that the human Smarca2 gene (hSmarca2), like its mouse counterpart (mSmarca2), also initiated a short transcript from intron 27 of the long transcript. We name the long and short transcripts as Smarca2-a and Smarca2-b, respectively. Like its human counterpart, mSmarca2-a also underwent alternative splicing at the 54-bp exon 29. The hSmarca2-b had two alternative initiation sites and underwent alternative splicing at three different 3' sites of exon 1 and at exons 2, 3 and/or 5. We identified nine hSmarca2-b mRNA variants that might produce five different proteins. mSmarca2-b also underwent alternative splicing at exon 3 and/or exon 5, besides alternatively retaining part of intron 1 in exon 1. Smarca2-b was expressed more abundantly than Smarca2-a in many cell lines and was more sensitive to serum starvation. Moreover, cyclin D1 also regulated the expression of both Smarca2-a and Smarca2-b in a complex manner. These data suggest that the functions of the Smarca2 gene may be very complex, not just simply inhibiting cell proliferation, and in certain situations may be elicited mainly by expressing the much less known Smarca2-b, not the better studied Smarca2-a and its products BRM proteins.

Patients were identified from an electronic prospective database. Records of all patients were reviewed for details of management, complications and follow-up. Patient satisfaction and quality of life in the postoperative period were determined using the BREAST-Q© questionnaire.
Results
Between October 2008 and August 2010, 21 patients underwent 28 dermal sling-assisted breast reconstruction procedures. Their median age was 48 (range 30–70) years. Median hospital stay was 5 (range 3–7) days. Drains were removed at a median of 5 (range 3–7) days after surgery. During the operation a median volume of 150 ml was added to the tissue expander. The most common postoperative complication was superficial -junction breakdown in five patients, followed by seroma and infection each in three patients, but no implant required removal. BREAST-Q© responses indicated a high level of satisfaction overall with the reconstructed breast.
Conclusion
Dermal sling-assisted immediate breast reconstruction has a low serious complication rate, provides stable soft tissue cover for the tissue expander and is associated with a high level of patient satisfaction. A larger pocket can be created, permitting more fluid to be added to the expander.

Abstract
Tissue engineering scaffolds with controlled long-term release of growth factors are constructed in an attempt to mimic the intelligent ability of the extracellular matrix (ECM) to release endogenous growth factors. In this study, collagen sponges (Collagen group) were modified by N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS) crosslinking (EDC/NHS group) and heparin immobilization (EDC/NHS-H group), and subsequently seeded with human umbilical vein endothelial cells (HUVECs). Native and modified sponges were pre-adsorbed with basic fibroblast growth factor (bFGF) to evaluate the sustained release and bioactive maintenance of bFGF from the sponges. We found that modified collagen matrices permitted HUVECs to proliferate and migrate well and to distribute uniformly. The EDC/NHS-H group exhibited an excellent sustained-release profile and bioactive maintenance of the pre-adsorbed bFGF as compared with the Collagen and EDC/NHS groups. These results suggest that heparin-functionalized collagen matrices can support a controlled release of bFGF and thus, have potential as a tissue engineering scaffold.

Abstract
OBJECTIVES Lipids are linked to many pathological processes including hepatic steatosis and liver malignancy. This study aimed to explore lipid metabolism in hepatitis C virus (HCV) and HCV-related hepatocellular carcinoma (HCC). METHODS Serum lipids were measured in normal, HCV and HCV-HCC patients. Whole-genome microarray was performed to identify potential signature genes involved in lipid metabolism characterizing normal vs. HCV vs. HCV-HCC conditions. RESULTS Serum cholesterol was significantly reduced in HCV and HCV-HCC patients compared with normal controls, whereas there was no difference in glucose and triglycerides. Microarray analysis identified 224 probe sets with known functional roles in lipid metabolism (anova, 1.5-fold, P ≤ 0.001). Gene-mediated fatty acid (FA) de novo synthesis and uptake were upregulated in HCV and this upregulation was further enhanced in HCC. Genes involved in FA oxidation were downregulated in both the HCV and HCC groups. The abnormality of cholesterol metabolism in HCV was associated with downregulation of genes involved in cholesterol biosynthesis, absorption and transportation and bile acid synthesis; this abnormality was further intensified in HCC. CONCLUSIONS Our data support the notion that HCV-related lipid metabolic abnormalities may contribute to hepatic steatosis and the development of cancer. Identification of these aberrations would stratify patients and improve treatment algorithms.

Abstract
OBJECTIVE To investigate the effect of continous perfusion with Danshen and heparin for treatment of femoral head necrosis. METHODS From April 2004 to June 2007,42 patients of femoral head necrosis were treated by contious perfusing with Dandshen and heparin, included 24 males and 18 females with an average age of 39.2 years ranging from 13 to 61 years. There were 18 patients on stage II, 13 patients on stage III, 11 patients on stage IV according to Ficat standard. The venous duct were inserted into femoral head then perfused Danshen and heparin into femoral head for 15 days. Every patient was carried out opacification before treatment and 1 month after operation. Every patient was evaluated according to Harris standard before treatment and 3, 6, 12 months after treatment. RESULTS All patients were followed-up for 32 to 68 months (means 42.7 months). The average scores of 18 patients on stage II on 3, 6, 12 months after treatment were (88.43 +/- 3.41), (94.37 +/- 3.47), (92.84 +/-4.29), respectively, and the scores after treatment were higher than the score (78.23 +/- 3.47) after treatment. The average scores of 13 cases on stage III on 3, 6, 12 after treatment were (82.94 +/- 3.31), (88.60 +/- 2.31), (86.09 +/- 3.17) respectivly, and the scores after treatment were higher than the score (66.11 +/- 4.50) before treatment. The average scores of 11 cases on stage IV on 3, 6, 12 months after treatment were (61.31 +/- 4.06), (59.2 +/- 7.31), (54.62 +/- 8.20) respectivly,and the scores on 3, 6 months after treatment were higher than the score (50.16 +/- 2.35) before treatment,but there was no obvious difference between before treatment and 12 months after treatment. The rank of phlebography of 18 cases on stage II and 13 cases on stage IlI were improved obvi ously 1 month after treatment,but there was no obvious difference in 11 cases of stage IV. CONCLUSION The method of contious perfusing with Danshen and heparin into femoral head has the advantage of little damage and good effect. It refers to patients in early stage (II and II ).

Abstract
Abstract
Background: Lysophosphatidic acid (LPA) is an important intercellular signaling molecule involved in a number of physiologic and pathophysiological processes. Elevated serum LPA was reported to be associated with liver fibrosis in patients with chronic hepatitis C. We have previously demonstrated that the enzyme mediated LPA generation- autotaxin(ATX) was overexpressed in hepatitis and hepatitis associated HCC. But the exact mechanism of the enhanced LPA signaling contributed to the initiation or progression of tumorigenesis in human liver cancer remains unclear.
Methods:
Human liver cancer cell lines Hep3B, HepG2 and Huh7 were serum-starved overnight and stimulated with LPA (18:1, Avanti Polar-Lipids, Inc., Alabaster, AL, USA) by different doses (0, 2.5, 5, 10 and 20 uM) and different time intervals (3, 8 and 16 hours). RNA was extracted using Qiagen kit (Qiagen, Valencia, CA) according to the manufacturer's protocol. Quantitative real-time PCR was applied to determine the expression of interleukin 1, beta (IL-1B), IL-6, tumor necrosis factor alpha(TNF-alpha), transforming growth factor alpha 1 (TGF-alpha1) and transforming growth factor beta1 (TGF-beta1) using standard commercially available TaqMAN probes (Applied Biosystems, Foster City, CA). The amount of target gene was normalized to the internal standard 18S rRNA (Hs99999901_s1) levels and reported as a relative value.
Results:
TNF-alpha mRNA level was rapidly induced more than 3-fold after stimulating with 2.5 uM LPA for 3 hours in Hep3B cells (P<0.01), but this induction did not show significant change in spite of increasing treatment time or LPA doses. The curves of TNF-alpha expression in Huh7 and HepG2 cells were nearly identical to that of Hep3B cells, Treatment with 2.5uM LPA for 3 hours induced more than 5- and 2- fold TNF-alpha mRNA in Huh7 and HepG2 cells respectively(p<0.001). Different dose or treatment time did not result in a significant increase of induction of TNF-alpha mRNA in these two liver cancer cell lines. Interestingly, LPA treatment had no effect on the mRNA expression of TGF-alpha1, TGF-beta1, IL-1 or IL-6 in these three liver cancer cell lines in spite of increasing LPA doses or time intervals.
Conclusions:
Our study demonstrates that LPA transcriptionally activates TNF-alpha expression in human liver cancer cell lines. TNF-alpha is known to induce hepatocytes apoptosis and is one of the few critical factors that prime liver regeneration. LPA-induced TNF-alpha production in liver cancer cells may be important not only for tumor behavior, but also has potential damage to normal tissues which in turn fuel the liver tumor progression.

Abstract
BACKGROUND Autotaxin (ATX) is an extracellular lysophospholipase D that generates lysophosphatidic acid (LPA) from lysophosphatidylcholine (LPC). Both ATX and LPA have been shown to be involved in many cancers. However, the functional role of ATX and the regulation of ATX expression in human hepatocellular carcinoma (HCC) remain elusive. RESULTS In this study, ATX expression was evaluated in tissues from 38 human HCC and 10 normal control subjects. ATX was detected mainly in tumor cells within tissue sections and its over-expression in HCC was specifically correlated with inflammation and liver cirrhosis. In addition, ATX expression was examined in normal human hepatocytes and liver cancer cell lines. Hepatoma Hep3B and Huh7 cells displayed stronger ATX expression than hepatoblastoma HepG2 cells and normal hepatocytes did. Proinflammtory cytokine tumor necrosis factor alpha (TNF-alpha) promoted ATX expression and secretion selectively in Hep3B and Huh7 cells, which led to a corresponding increase in lysophospholipase-D activity. Moreover, we explored the mechanism governing the expression of ATX in hepatoma cells and established a critical role of nuclear factor-kappa B (NF-kappaB) in basal and TNF-alpha induced ATX expression. Further study showed that secreted enzymatically active ATX stimulated Hep3B cell invasion. CONCLUSIONS This report highlights for the first time the clinical and biological evidence for the involvement of ATX in human HCC. Our observation that links the TNF-alpha/NF-kappaB axis and the ATX-LPA signaling pathway suggests that ATX is likely playing an important role in inflammation related liver tumorigenesis.

Abstract
Nuclear factor-kappaB (NF-kappaB) has been shown to play an important role in the development and progression of cancer. In this study, we systematically examined NF-kappaBp65 signaling pathway in both human hepatocellular carcinoma (HCC) tissue and HCC cell lines. NF-kappaBp65 signaling pathway is aberrantly expressed and activated in both human HCC tissue and HCC Hep3B cells. Inhibition of NF-kappaB activity significantly reduced proliferation and invasion of Hep3B cells as well as down-regulated the expression of invasion-related molecules including matrix metalloproteinase (MMP)-2, MMP-9, membrane type-1 MMP (MT1-MMP), urokinase plasminogen activator (uPA) and vascular endothelial growth factor (VEGF). Hep3B cells exhibited a dose-dependent increase in apoptosis after receiving sorafenib treatment. Inhibition of NF-kappaB activity strongly sensitized Hep3B cells to sorafenib-induced cell death. Mechanistically, combined treatment of sorafenib and NF-kappaB inhibition enhanced inhibition of MAPK signaling and down-regulation of anti-apoptotic protein Mcl-1 expression. These observations indicate that inhibition of NF-kappaB may be a potential antineoplastic therapy for HCC, especially the combination of NF-kappaB inhibition and sorafenib provides a novel therapeutic strategy for patients with advanced-stage HCC.

Abstract
Meconium aspiration syndrome (MAS) is still one of the most challenged diseases for the neonatologists. We reviewed our earlier studies of MAS in an attempt to provide some idea for more understanding of MAS. This study is a retrospective review and summarization of our earlier studies in MAS at two tertiary neonatal centers in Taiwan. Incidence of MAS was decreased sharply in Taiwan. MAS infants who required resuscitation in the birth room being out-born, birth asphyxia and infants who developed persistent pulmonary hypertension (PPHN) and pneumothrax were associated with increasing mortality. In MAS infants who neither required mechanical ventilation nor had a history suggestive of perinatal infection, antibiotic treatments would not affect the outcome of MAS. Dexamethasone did reduce inflammation response and improve cardiopulmonary perfusion. However, steroids did not prevent the development of PPHN. Our review provided the risk factors of mortality for MAS. Antibiotic treatments should not be a routine for every infant with MAS. Although steroids reduce pulmonary inflammation, their role in the prevention of PPHN remains to be further studied.

Abstract
Nuclear factor Y (NF-Y) is a ubiquitous transcription factor composed of three distinct subunits (NF-YA, NF-YB, and NF-YC). We found that the Arabidopsis thaliana NFYA5 transcript is strongly induced by drought stress in an abscisic acid (ABA)-dependent manner. Promoter:beta-glucuronidase analyses showed that NFYA5 was highly expressed in vascular tissues and guard cells and that part of the induction by drought was transcriptional. NFYA5 contains a target site for miR169, which targets mRNAs for cleavage or translational repression. We found that miR169 was downregulated by drought stress through an ABA-dependent pathway. Analysis of the expression of miR169 precursors showed that miR169a and miR169c were substantially downregulated by drought stress. Coexpression of miR169 and NFYA5 suggested that miR169a was more efficient than miR169c at repressing the NFYA5 mRNA level. nfya5 knockout plants and plants overexpressing miR169a showed enhanced leaf water loss and were more sensitive to drought stress than wild-type plants. By contrast, transgenic Arabidopsis plants overexpressing NFYA5 displayed reduced leaf water loss and were more resistant to drought stress than the wild type. Microarray analysis indicated that NFYA5 is crucial for the expression of a number of drought stress-responsive genes. Thus, NFYA5 is important for drought resistance, and its induction by drought stress occurs at both the transcriptional and posttranscriptional levels.
