HNF4A was also associated with tumor mutation burden (r = 0. 28,P<0. 0001) and microsatellite instability (r = 0. 13,P<0. 01) .After knockdown of HNF4A, cell proliferation ability was significantly inhibited ,and cell cycle was arrested at G0 / G1 phase.@*Conclusion@#HNF4A expression significantly increased in gastric cancer tissues,which is associated with poor prognosis ,and may also be involved in immune regulation. Knockdown of HNF4A can inhibit the proliferation of gastric cancer cells.
ABSTRACT
BACKGROUND: Lignocellulose is considered a renewable organic material, but the industrial production of biofuel from lignocellulose is challenging because of the lack of highly active hydrolytic enzymes. The guts of herbivores contain many symbiotic microorganisms that have evolved to hydrolyze plant lignocellulose. Chinese bamboo rats mainly consume high-fiber foods, indicating that some members of the intestinal tract microbiota digest lignocellulose, providing these rats with the energy required for growth. RESULTS: Here, we used metagenomics to analyze the diversity and functions of the gut microbiota in Chinese bamboo rats. We identified abundant populations of lignocellulose-degrading bacteria, whose main functions involved carbohydrate, amino acid, and nucleic acid metabolism. We also found 587 carbohydrate-active enzyme genes belonging to different families, including 7 carbohydrate esterase families and 21 glycoside hydrolase families. The glycoside hydrolase 3, glycoside hydrolase 1, glycoside hydrolase 43, carbohydrate esterase 4, carbohydrate esterase 1, and carbohydrate esterase 3 families demonstrated outstanding performance. CONCLUSIONS: The microbes and enzymes identified in our study expand the existing arsenal of proficient degraders and enzymes for lignocellulosic biofuel production. This study also describes a powerful approach for targeting gut microbes and enzymes in numerous industries.

OBJECTIVE@#To investigate the mid-to-long-term efficacy of patients with chronic ankle instability combined with posterior impingement syndrome after 3-9 years of follow-up, and to analyze the influencing factors.@*METHODS@#From February 2010 to December 2015, 46 patients underwent concurrent lateral ankle ligament repair with posterior ankle arthroscopic surgery at the Institute of Sports Medicine, Peking University Third Hospital. The patient was first placed in a prone position and underwent arthroscopic debridement for the posterior impingement. After finishing the posterior arthroscopy, the surgeon and assistants first translated the patient to the affected side, then turned to the healthy side, and changed the position to the supine position. During the turning over, another assistant held the arthroscope and the instrument to ensure that it was sterile and could be used without replacement. The anterior ankle arthroscopy was operated if necessary and the lateral ankle ligament repair was anatomic repaired with anchors. The 42 patients were followed up, including 26 males and 16 females. The average age was (28.9±10.0) years. The patient's clinical symptoms, joint stability, mobility and motor function were compared by questionnaire and physical examination. The preoperative and postoperative visual analogue scale (VAS) scores, American Orthopaedic Foot and Ankle Society (AOFAS) scores, Tegner scores were compared, and the clinical scores and the patient age, gender, height and weight were compared. The correlations between body mass index (BMI), preoperative duration, surgery duration, and cartilage injury were analyzed.@*RESULTS@#The mean follow-up time was (71.8±22.8) months. The postoperative VAS scores (1.0 vs. 5.0, P<0.001), AOFAS scores (92 vs. 80, P<0.001), and Tegner scores (6.5 vs. 2, P<0.001) were significantly superior to the preoperative levels. The excellent and good rate was 97.6%. The postoperative VAS score (t=2.719, P=0.10), AOFAS score (t=-2.853, P=0.10), Tegner score (t=-3.443, P=0.001) and time to return exercise (t=2.814, P=0.008) were negatively correlated with the patient age, and the postoperative VAS score was negatively correlated with cartilage injury (Z=-2.195, P=0.028).@*CONCLUSION@#The mid-to-long-term clinical outcomes of the chronic ankle ligament instability combined with the posterior impingement were good. The age of the patients was negatively correlated with the clinical outcome. The combined cartilage injury could aggravate the postoperative pain.

Reactive oxygen species (ROS) are highly reactive chemical species that may cause irreversible tissue damage, and play a critical role in cardiovascular diseases. Hydrogen sulfide (H2S) is a gasotransmitter that acts as a ROS scavenger with cardio-protective effects. In this study, we investigated the cytoprotective effect of H2S against H2O2-induced apoptosis in cardiomyocytes. H9c2 rat cardiomyoblasts were treated with H2S (100 μM) 24 h before challenging with H2O2 (100 μM). Apoptosis was then assessed by annexin V and PI, and mitochondrial membrane potential was measured using a fluorescent probe, JC-1. Our results revealed that H2S improved cell viability, reduced the apoptotic rate, and preserved mitochondrial membrane potential. An increased Bcl-2 to Bax ratio was also seen in myocytes treated with H2S after H2O2-induced stress. Our findings indicated a therapeutic potential for H2S in preventing myocyte death following ischemia/reperfusion.

ABSTRACT
BACKGROUND: There is limited literature in the management of chronic urticaria in children. Treatment algorithms are generally extrapolated from adult studies. OBJECTIVE: Utility of a weight and age-based algorithm for antihistamines in management of chronic spontaneous urticaria (CSU) in childhood. To document associated factors that predict for step of control of CSU and time taken to attain control of symptoms in children. METHODS: A workgroup comprising of allergists, nurses, and pharmacists convened to develop a stepwise treatment algorithm in management of children with CSU. Sequential patients presenting to the paediatric allergy service with CSU were included in this observational, prospective study. RESULTS: Ninety-eight patients were recruited from September 2012 to September 2013. Majority were male, Chinese with median age 4 years 7 months. A third of patients with CSU had a family history of acute urticaria. Ten point two percent had previously resolved CSU, 25.5% had associated angioedema, and 53.1% had a history of atopy. A total of 96.9% of patients achieved control of symptoms, of which 91.8% achieved control with cetirizine. Fifty percent of all the patients were controlled on step 2 or higher. Forty-seven point eight percent of those on step 2 or higher were between 2 to 6 years of age compared to 32.6% and 19.6% who were 6 years and older and lesser than 2 years of age respectively. Eighty percent of those with previously resolved CSU required an increase to step 2 and above to achieve chronic urticaria control. CONCLUSION: We propose a weight- and age-based titration algorithm for different antihistamines for CSU in children using a stepwise approach to achieve control. This algorithm may improve the management and safety profile for paediatric CSU patients and allow for review in a more systematic manner for physicians dealing with CSU in children.

BACKGROUND: Cyclooxygenase-2 (COX-2) inhibitors have been found to be safe alternatives in adults with cross-intolerant hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs). However they are usually not prescribed in children and there is little information about their tolerance in the pediatric age group. OBJECTIVE: This study aims to evaluate the tolerance to etoricoxib in children with hypersensitivity to multiple antipyretics. METHODS: A retrospective case series of children diagnosed with hypersensitivity reactions to NSAIDs and/or paracetamol who underwent a drug provocation test (DPT) with etoricoxib. Information on atopy, family history of allergic diseases, and medication usage was collected. Outcomes of the DPTs and tolerance to etoricoxib were also evaluated. RESULTS: A total of 24 children, mean age 13.5 years, had a diagnosis of cross-intolerant hypersensitivity to NSAIDs and/or paracetamol. All except one patient successfully tolerated an oral challenge with etoricoxib. Of those who passed the DPT, the majority continued to use etoricoxib with no problems. It was found to be moderately effective in reducing fever and pain. CONCLUSION: Etoricoxib can be used as a safe alternative in older children with hypersensitivity to multiple antipyretics.

<p><b>OBJECTIVE</b>To observe the effects of miR-224 antisense oligonucleotide (ASO) on the proliferation and apoptosis of gastric cancer cells in vitro and vivo.</p><p><b>METHODS</b>The expression of miR-224 in the cancer tissues and their adjacent tissues in 120 gastric cancer patients were detected by real-time quantitative PCR. The biological effects of miR-224 ASO on human gastric cancer SGC7901 cells was assessed by MTT assay, clone formation assay, flow cytometry and in vivo experiment in nude mice.</p><p><b>RESULTS</b>Compared with the control group (0.50 ± 0.07), miR-224 ASO significantly reduced the miR-224 mRNA expression in the cancer patients (0.09 ± 0.01, P < 0.05). MTT assay results showed that the survival rate of gastric cells at 24 h, 48 h and 72 h was 53.6%, 59.1% and 70.1% in the miR-224 ASO group, and 12.3%, 17.4% and 24.7%, respectively, in the control group (P < 0.05 for all). Clone formation assay revealed that clone formation rate in the miR-224 ASO group was (5.33 ± 0.74)%, significantly lower than the (33.33 ± 8.38)% in the control group (P < 0.05). Flow cytometry indicated that the apoptotic index was (15.68 ± 1.46)% in the miR-224 ASO group and (3.36 ± 0.88)% in the control group (P < 0.01). In addition, the expressions of Bcl2 mRNA and protein were 1.05 ± 0.04 and 0.21 ± 0.03 in the miR-224 ASO group, significantly lower than that in the control group (4.87 ± 0.96 and 0.88 ± 0.09, P < 0.01). The in vivo study further showed that the tumor volume in the experimental group is significantly smaller than that in the control group (P = 0.01).</p><p><b>CONCLUSIONS</b>MiR-224 is overexpressed in human gastric cancer. Reducing the expression of miR-224 can effectively inhibit the growth and promote apoptosis of gastric cancer cells. miR-224 may become a new target for the regulation of gene expression in gastric cancer.</p>

Coptidis Rhizoma and Aconiti Kusnezoffii Radix represent hot Chinese medicine and cold Chinese medicine respectively. The purpose of this study is to observe the differentiation effect of Coptidis Rhizoma and Aconiti Kusnezoffii Radix on lewis lung cancer and compare effect of hot Chinese medicine and cold Chinese medicine on tumor progression. In this study, the rat serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix was prepared to treat lewis lung cancer cells in vitro, and effects of the serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix on cell differentiation, proliferation, adhesion, succinic dehydrogenase (SDH) activity and gap-junction intercellular communication (GJIC) were investigated. In vivo, the subcutaneous implant model and pulmonary metastasis model of lewis lung cancer were established. Tumor bearing mice were taken water decoction of coptis chinensis or aconite by intragastric administration bid for four weeks, and the influences of coptis chinensis and aconite on tumor progression were evaluated by body temperature, blood oxygen saturation, red cell ATPase, blood rheology, intratumor hypoxia, capillary permeability and GJIC. The results showed that the serum containing aconite could induce cell differentiation, inhibit cell proliferation and migration, promote SDH activity and GJIC in lewis lung cancer cells. The serum containing Coptidis Rhizoma increased cell adhesion and decreased SDH activity and GJIC without cell differentiation although it also suppressed cell proliferation. Aconiti Kusnezoffii Radix water decoction could keep body temperature, blood oxygen saturation, red cell ATPase and blood rheology, and improve intratumor hypoxia, capillary permeability and GJIC in tumor bearing mice, which led to slower tumor growth and less metastasis. Coptidis Rhizoma water decoction decreased body temperature, blood oxygen saturation, red cell ATPase, blood rheology and GJIC, and promoted intratumor hypoxia and capillary permeability, which resulted to more tumor metastasis although it also prevented tumor growth. These results suggested that the hot Chinese medicine could induce tumor cell differentiation and prevent tumor poison invagination, which is better for tumor treatment than cold Chinese medicine.

<p><b>BACKGROUND</b>Interleukin-23 (IL-23) is a pro-inflammatory cytokine that is thought to be central to the development of autoimmune diseases. This study was conducted to determine whether or not the serum concentration of IL-23 is elevated in patients with rheumatoid arthritis (RA), and to determine the relationship between the IL-23 level and disease activity in RA patients.</p><p><b>METHODS</b>Serum samples were obtained from 59 patients with RA and 30 healthy controls. The clinical parameters of disease activity were determined, including the 28-joint disease activity score (DAS28), C-reactive protein (CRP), rheumatoid factor (RF) levels, and the degree of bony erosions based on X-rays. The levels of IL-23 and IL-17 were determined by enzyme-linked immunosorbent assay (ELISA). The correlations between the serum levels of IL-23 and disease activity parameters of patients with RA were determined.</p><p><b>RESULTS</b>The serum IL-23 level was significantly elevated in patients with RA compared to healthy controls. The serum IL-23 levels in the RA patients correlated with IL-17 and CRP levels, and the DAS28. The levels of IL-23 based on X-ray classification phase I, II, III, and IV were gradually elevated in RA patients.</p><p><b>CONCLUSIONS</b>The levels of serum IL-23 in RA patients were higher than in healthy controls. Thus, elevated serum IL-23 levels may be useful markers to detect active RA. In addition, IL-23 is involved in disease progression and bony erosions in patients with RA.</p>

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of the treatment for thoracolumbar fractures with transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach.</p><p><b>METHODS</b>From June 2007 to December 2008, 19 cases of thoracolumbar fractures were treated with transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach. There were 7 female and 12 male, ranging from 21 to 57 years of age (mean 40.8 years) at surgery. The time from injury to surgery varied from 1 d to 5 d (mean 2.9 d). Nineteen patients all suffered from single thoracolumbar fracture with the distribution of injury level being T(11) in 1, T(12) in 5, L(1) in 9, and L(2) in 4. According to Denis fracture classification, there were 5 compression fractures and 14 burst fractures. The mean preoperative ratio of the anterior height of the body was 57.2%, kyphosis angle was 17.6° and occupation of spinal canal was 27.7%. The mean preoperative load-sharing classification of spine fractures was 5.2. Based on the ASIA neurologic grading system, preoperative neurological function was grade B in 2 cases, C in 9 and D in 8.</p><p><b>RESULTS</b>Median operating time was 83.8 min (range 60-95 min) and median blood loss was 133 ml (range 90 - 200 ml). Infection did not occur in any of the patients and the operative incisions were healing well. Average follow-up time was 19.2 months (range 12 - 36 months). At the latest follow-up, the height of the anterior border was corrected to 88.4%, the kyphosis angle was 6.1°, and the occupation of spinal canal was 8.2% on average. The postoperative neurologic function of all 19 patients was improved with grade D in 2 cases and E in 17. There were no instances of instrumentation failure and no patient had persistent postoperative back pain.</p><p><b>CONCLUSIONS</b>Transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach could provide reliable neurologic improvement in patients with incomplete neurologic deficit, and could prevent the development of kyphosis.Furthermore, it has the obvious advantages of less invasive and blood loss, and decreases the risks of postoperative lumbodorsal pain.</p>

<p><b>OBJECTIVE</b>To evaluate the surgical effects of treatment of scaphoid fracture with retrograde internal fixation using absorbable screw.</p><p><b>METHODS</b>From December 2001 to December 2007, 18 cases of scaphoid fracture were treated with absorbable screw by retrograde internal fixation. There were 12 males and 6 females with an average age of 26 years ranging from 17 to 40 years. Ten cases were medium fractures of scaphoid and 8 cases were proximal fraxtures.</p><p><b>RESULTS</b>All patients were followed-up for from 12 to 36 months (means 25 months). Among them, 17 cases were union and 1 case was nonunion. The mean time of union was 13 weeks. The mean range of motion of wrist was about 90% and mean scratch strength of wrist was about 95% to fine lateral. There were no pain in 14 cases, and slight pain in 3, medial pain in 1 casea of ununion. According to Cooney's clinical evaluation system, the score was increased from (68.2 +/- 1.5) before operation to (88.7 +/- 1.2) after operation, the postoperative score was higher than preoperative remarkable; 9 patients were fine, 8 were good and 1 was bad.</p><p><b>CONCLUSION</b>This technology had some advantage such as simple surgery, decreasing demonstrate rest blood circulation, stable fixation, reducing bone healing time and increasing healing time. It is an effective way to treat scaphoid fracture.</p>
