Resveratrol as a cardioprotective adjuvant for 5-fluorouracil in the treatment of gastric cancer cells

The clinical application of 5-fluorouracil (5-Fu), a potent chemotherapeutic agent, is often hindered by its well-documented cardiotoxic effects. Nevertheless, natural polyphenolic compounds like resveratrol (RES), known for their dual anti-tumor and cardioprotective properties, are potential adjunct therapeutic agents. In this investigation, we examined the combined utilization of RES and 5-Fu for the inhibition of gastric cancer using both in vitro and in vivo models, as well as their combined impact on cardiac cytotoxicity. Our study revealed that the co-administration of RES and 5-Fu effectively suppressed MFC cell viability, migration, and invasion, while also reducing tumor weight and volume. Mechanistically, the combined treatment prompted p53-mediated apoptosis and autophagy, leading to a considerable anti-tumor effect. Notably, RES mitigated the heightened oxidative stress induced by 5-Fu in cardiomyocytes, suppressed p53 and Bax expression, and elevated Bcl-2 levels. This favorable influence enhanced primary cardiomyocyte viability, decreased apoptosis and autophagy, and mitigated 5-Fu-induced cardiotoxicity. In summary, our findings suggested that RES holds promise as an adjunct therapy to enhance the efficacy of gastric cancer treatment in combination with 5-Fu, while simultaneously mitigating cardiotoxicity.

Moxibustion improves experimental colitis in rats with Crohn's disease by regulating bile acid enterohepatic circulation and intestinal farnesoid X receptor / 中西医结合学报

OBJECTIVE@#This study was conducted to explore the mechanism of intestinal inflammation and barrier repair in Crohn's disease (CD) regulated by moxibustion through bile acid (BA) enterohepatic circulation and intestinal farnesoid X receptor (FXR).@*METHODS@#Sprague-Dawley rats were randomly divided into control group, CD model group, mild moxibustion group and herb-partitioned moxibustion group. CD model rats induced by 2,4,6-trinitrobenzene sulfonic acid were treated with mild moxibustion or herb-partitioned moxibustion at Tianshu (ST25) and Qihai (CV6). The changes in CD symptoms were rated according to the disease activity index score, the serum and colon tissues of rats were collected, and the pathological changes in colon tissues were observed via histopathology. Western blot, immunohistochemistry (IHC) and immunofluorescence were used to evaluate the improvement of moxibustion on intestinal inflammation and mucosal barrier in CD by the BA-FXR pathway.@*RESULTS@#Mild moxibustion and herb-partitioned moxibustion improved the symptoms of CD, inhibited inflammation and repaired mucosal damage to the colon in CD rats. Meanwhile, moxibustion could improve the abnormal expression of BA in the colon, liver and serum, downregulate the expression of interferon-γ and upregulate the expression of FXR mRNA, and inhibit Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) mRNA. The IHC results showed that moxibustion could upregulate the expression of FXR and mucin2 and inhibit TLR4 expression. Western blot showed that moxibustion inhibited the protein expression of TLR4 and MyD88 and upregulated the expression of FXR. Immunofluorescence image analysis showed that moxibustion increased the colocalization sites and intensity of FXR with TLR4 or nuclear factor-κB p65. In particular, herb-partitioned moxibustion has more advantages in improving BA and upregulating FXR and TLR4 in the colon.@*CONCLUSION@#Mild moxibustion and herb-partitioned moxibustion can improve CD by regulating the enterohepatic circulation stability of BA, activating colonic FXR, regulating the TLR4/MyD88 pathway, inhibiting intestinal inflammation and repairing the intestinal mucosal barrier. Herb-partitioned moxibustion seems to have more advantages in regulating BA enterohepatic circulation and FXR activation.

Lysosome TMEM175 Potassium Channel Protein and Parkinson’s Disease / 中国生物化学与分子生物学报

Parkinson’s disease (PD)is a complex neurodegenerative disorder by motor impairments and non-motor symptoms. While dopamine-based therapies are effective in fighting the symptoms in the early stages of the disease‚ a lack of neuroprotective drugs means that the disease continues to progress. New disease modifying therapies and novel therapeutic strategies are in high demand for PD patients. Genetic studies indicated that both rare and common genetic variants could induce the development PD. As a risk candidate gene for Parkinson’s disease‚ TMEM175 encodes a lysosomal potassium channel protein with new structures‚ and the protein plays an important role in maintaining lysosomal membrane potential and pH stability. With the in-depth understanding for its structure and function‚ TMEM175 deficiency results in decreased lysosomal catalytic activity and the pathological aggregation of α-synuclein. In view of the importance of lysosome potassium channel TMEM175‚ it could be an interesting target for the development of drugs to treat Parkinson’s disease and other neurodegenerative diseases. Herein we review the structure and function TMEM175‚ and focuses on its involvement in the occurrence and development of PD by affecting the function of lysosome as a homeostatic regulator. Future drug screenings based on lysosome TMEM175 may be carried out to maintain the active state or enhance the expression of TMEM175 to improve the condition of PD patients. Further investigations are needed to study how to maintain the balance between the open and closed state of TMEM175 channels to regulate the ion homeostasis of lysosomes. Studies of this ion channel protein will bring new strategies and ideas for the treatment of PD‚ and provide support for establishing the molecular status of TMEM175 in the diagnosis and treatment of PD.

SHANK2 is a frequently amplified oncogene with evolutionarily conserved roles in regulating Hippo signaling

Dysfunction of the Hippo pathway enables cells to evade contact inhibition and provides advantages for cancerous overgrowth. However, for a significant portion of human cancer, how Hippo signaling is perturbed remains unknown. To answer this question, we performed a genome-wide screening for genes that affect the Hippo pathway in Drosophila and cross-referenced the hit genes with human cancer genome. In our screen, Prosap was identified as a novel regulator of the Hippo pathway that potently affects tissue growth. Interestingly, a mammalian homolog of Prosap, SHANK2, is the most frequently amplified gene on 11q13, a major tumor amplicon in human cancer. Gene amplification profile in this 11q13 amplicon clearly indicates selective pressure for SHANK2 amplification. More importantly, across the human cancer genome, SHANK2 is the most frequently amplified gene that is not located within the Myc amplicon. Further studies in multiple human cell lines confirmed that SHANK2 overexpression causes deregulation of Hippo signaling through competitive binding for a LATS1 activator, and as a potential oncogene, SHANK2 promotes cellular transformation and tumor formation in vivo. In cancer cell lines with deregulated Hippo pathway, depletion of SHANK2 restores Hippo signaling and ceases cellular proliferation. Taken together, these results suggest that SHANK2 is an evolutionarily conserved Hippo pathway regulator, commonly amplified in human cancer and potently promotes cancer. Our study for the first time illustrated oncogenic function of SHANK2, one of the most frequently amplified gene in human cancer. Furthermore, given that in normal adult tissues, SHANK2's expression is largely restricted to the nervous system, SHANK2 may represent an interesting target for anticancer therapy.

A new fixation and reconstruction method versus arthroscopic reconstruction for treating avulsion fracture at the tibial insertion of the knee posterior cruciate ligament: study protocol for a non-randomized controlled trial and preliminary results / 中国组织工程研究

BACKGROUND: Arthroscopic reconstruction for treatment of avulsion fracture at the tibial insertion of the knee posterior cruciate ligament (PCL) can minimize surgical trauma to the largest degree. However, its implants have relatively poor stability; therefore, functional exercise cannot be performed in the early stages after surgery, which is inconducive to knee function recovery. It is extremely challenging to perform traditional open reduction with internal fixation to repair avulsion fractures at the tibial insertion of the knee PCL. Often, the crushed bones cannot be firmly fixed, leading to a poor repair effect. OBJECTIVE: To design a new inverted "L"-shaped incision in the popliteal fossa through which bone plates were inserted to fix the crushed bones and to reconstruct PCL tension, facilitating knee function recovery; to compare the therapeutic effects of this new fixation and reconstruction method, and arthroscopic reconstruction for treating avulsion fracture at the tibial insertion of the knee PCL. METHODS: A prospective, single-center, non-randomized controlled trial. One hundred and eighty patients (knees) with avulsion fracture at the tibial insertion of the knee PCL will be assigned to two groups based on treatment methods: arthroscopic reconstruction group (n = 90;fracture fixation and repair under the arthroscope) and new method group (n = 90; bone plates will be inserted through an "L"-shaped incision in the popliteal fossa to fix the crushed bones and reconstruct PCL tension). After surgery, these patients will be followed up for 6 weeks, 6 months, and 12 months. RESULTS AND CONCLUSION: The primary outcome measure is the excellent and good rate of knee function recovery at 12 months after surgery as evaluated by Lysholm Knee Scoring Scale score (Herein referred to as Lysholm score). The secondary outcome measures are the excellent and good rate of knee function recovery before surgery, 6 weeks and 6 months after surgery; Lysholm score before surgery, 6 weeks, 6 months and 12 months after surgery; Hospital for Special Surgery (HSS) knee score, Visual Analogue Scale (VAS) score, posterior drawer test negative rate, X-ray morphology of the knee before surgery, and 6 weeks, 6 months, and 12 months after surgery and; incidence of adverse events at 6 weeks, 6 months and 12 months after surgery. Results of a preliminary study involving 62 patients (knees) with avulsion fracture at the tibial insertion of the knee PCL showed that posterior drawer test negative rate and Lysholm score were significantly higher in the new method group compared to the arthroscopic reconstruction group (P < 0.05) at 3 months after surgery. This study will be performed to compare the therapeutic effects of bone plate insertion through an "L"-shaped incision made in the popliteal fossa to fix the crushed bones and to reconstruct PCL tension, and traditional fracture fixation and repair under the arthroscope to treat avulsion fracture at the tibial insertion of the knee PCL. We believe that the former method will be superior to the latter one because it can fix the avulsion fracture more firmly, facilitating knee function recovery. This study was approved by Medical Ethics Committee of Cangzhou Central Hospital of China (approval No. 2017-120-01). This study will be performed in strict accordance with the Declaration of Helsinki formulated by the World Medical Association. Participants provided signed informed consent prior to participation in the study. This study was designed in December 2017. Patient recruitment and data collection will begin in April 2018. Patient recruitment will end in June 2019. Data analysis will be performed in August 2020. The study will be completed in October 2020. Results will be disseminated through presentations at scientific meetings and/or by publication in a peer-reviewed journal. This trial was registered with the Chinese Clinical Trial Registry (registration number:ChiCTR1800015026). The version of this study protocol is (1.0).

Long-Term Outcome of Dynesys Dynamic Stabilization for Lumbar Spinal Stenosis / 中华医学杂志(英文版)

<p><b>Background</b>Many clinical studies over the past decade have indicated positive outcomes for patients treated with Dynesys dynamic stabilization for lumbar degenerative disease. However, long-term outcomes of Dynesys for lumbar spinal stenosis are rarely reported. The aim of this study was to analyze the long-term clinical and radiologic outcomes for patients with lumbar spinal stenosis treated with Dynesys stabilization.</p><p><b>Methods</b>Thirty-eight patients with lumbar spinal stenosis were treated with Dynesys stabilization from July 2008 to March 2010. The minimal duration of follow-up was 72 months. The patients were divided into stenosis and spondylolisthesis groups according to degenerative spondylolisthesis. Clinical outcomes were evaluated using the Oswestry Disability Index (ODI) and visual analog scale (VAS). Radiographic evaluations included range of motion (ROM) and the disc heights of stabilized segments and the upper adjacent segments. We also evaluated the occurrence of radiographic and symptomatic adjacent segment degeneration (ASD).</p><p><b>Results</b>There were 23 patients in stenosis group and 15 patients in spondylolisthesis group. The ODI scores were significantly improved at the final follow-up evaluation, as compared to the baseline values (16.1 ± 5.7 vs. 57. 2 ± 14.2, t = 61.41, P < 0.01). The VAS scores for back and leg pain were significantly improved from 4.82 ± 0.89 and 4.04 ± 0.82 preoperatively to 0.93 ± 0.61 and 0.54 ± 0.51 postoperatively (t = 6.59, P < 0.01, and t = 5.91, P < 0.01, respectively). There were no differences between the two groups with respect to VAS and ODI scores. The ROM of stabilized segments decreased significantly from 7.8° ± 2.4° to 4.5° ± 1.5° (t = 7.18, P < 0.05), while the upper adjacent segments increased significantly from 8.3° ± 2.4° to 10.4° ± 2.4° (t = 2.87, P = 0.01). The change in disc height of stabilized segments was not significant (11.9 ± 2.1 preoperatively vs. 12.5 ± 1.5 postoperatively, t = 1.43, P = 0.15), whereas the decrease in disc height of the upper adjacent segments was significant (12.5 ± 2.0 preoperatively vs. 11.0 ± 1.7 postoperatively, t = 2.94, P = 0.01). The occurrence of radiographic and symptomatic ASD was 16% (6/38) and 3% (1/38), respectively.</p><p><b>Conclusions</b>Decompression and Dynesys stabilization for lumbar stenosis with or without spondylolisthesis showed good long-term clinical and radiographic results. Lumbar stenosis with or without Grade I spondylolisthesis, particularly in patients <60 years of age with mild-to-moderate lumbar disc degeneration, would be one of the main indications for the Dynesys system.</p>

Effect of cataract surgery on intraocular pressure in supine and lateral decubitus body postures.

Purpose: To investigate the effect of phacoemulsification on intraocular pressure (IOP) in different recumbent body postures including supine and lateral decubitus (LD) positions. Materials and Methods: This prospective, observational study included patients who had no glaucoma and who had planned to undergo phacoemulsification and intraocular lens implantation in one eye. Before and 1 month after cataract surgery, IOP was measured in both eyes using the Tono‑Pen AVIA. We measured IOP in the sitting, supine, and LD (with the operated eye placed on the lower side) positions. IOP was measured 10 min after assuming each position in a randomized sequence. The Wilcoxon signed‑rank test was used to compare the IOP changes before and 1 month after phacoemulsification in all postures. Results: Twenty‑nine patients participated in this study. Postoperative IOP was lower than the preoperative IOP when measured by Goldmann applanation tonometry in the sitting position (13.8 ± 1.9 mmHg vs. 12.6 ± 2.1 mmHg, P = 0.007). The postoperative IOP was lower than the preoperative IOP for the supine and LD positions. The average IOP reduction of the operated eye was 0.6 mmHg, 1.7 mmHg, and 3.0 mmHg in the sitting, supine, and LD positions, respectively (sitting vs. supine, P = 0.048; sitting vs. LD, P = 0.001; supine vs. LD, P = 0.028). In the nonoperated eye, IOP did not change significantly after surgery (all P > 0.05). Conclusions: Cataract surgery lowered IOP in the sitting position as well as in the supine and LD positions. Such postoperative IOP reductions were greater in the recumbent positions than in the sitting position.

<p><b>BACKGROUND</b>Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM). Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM.</p><p><b>METHODS</b>Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L) and hemilaminectomy (Group H). Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA), and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared.</p><p><b>RESULTS</b>Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41%) than in Group H (62.72 ± 3.86%) (P < 0.01).</p><p><b>CONCLUSIONS</b>Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.</p>

Dynesys dynamic stabilization system for the lumbar degenerative disease: a preliminary report from China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Dynesys dynamic stabilization system was first implanted in patients in 1994, and introduced to China in 2007. Therefore, it was a new technique for Chinese orthopedics and hence necessary to collect clinical data about Dynesys in China. The objective of this study was to report the preliminary results of Dynesys for the lumbar degenerative disease in China.</p><p><b>METHODS</b>Twenty-seven patients were treated with the Dynesys between July 2007 and January 2009. The diagnosis included degenerative spondylolisthesis (12 cases), degenerative spinal stenosis (nine cases), and lumbar intervertebral disc herniation (six cases). Back pain and leg pain were evaluated using 100-mm visual analog scales (VAS). The Oswestry Disability Index (ODI) was used to evaluate the patients' function. The intervertebral disc height and range of motion at the operative level were taken on radiographs.</p><p><b>RESULTS</b>All the patients were followed-up, with an average of (22.40 ± 4.23) months (range 15-32 months). VAS of back pain and leg pain were improved significantly (P < 0.05) at follow-up. The ODI scores were reduced from (62.58 ± 12.01)% preoperatively to (15.01 ± 5.71)% at follow-up (P < 0.05). The preoperative mean height of the intervertebral disc was (11.21 ± 1.58) mm (range 8.5-13.8 mm) and mean was (10.10 ± 1.78) mm (range 7.0-13.4 mm) at follow-up (P < 0.05). The mean range of motion of the implanted segment was (6.00 ± 1.79)° (range 2.5-9.3°) preoperatively and (5.47 ± 1.27)° (range 2.9-7.8°) at follow-up (P = 0.11).</p><p><b>CONCLUSIONS</b>The preliminary results of Dynesys for the lumbar degenerative disease in China are similar to the published results of other countries. It can significantly improve the clinic symptoms and preserved motion at the level of implantation. However, the long-term follow-up data need to be collected.</p>

<p><b>OBJECTIVES</b>To suggest the clinical classification of the far-lateral lumbar disc herniation and offer the considerations for clinical choice of different surgical procedures.</p><p><b>METHODS</b>According to the locations of the herniated disc and relevant clinical symptoms, the far-lateral lumbar disc herniation was divided into three types: Type I: posterolateral and foraminal herniation(double herniations); Type II: foraminal disc herniation and Type III: extraforaminal herniation. From January 2002 to January 2007, 38 patients with far lateral lumbar disc herniation underwent surgery in the institute. The surgical options were decided by means of the classification. The surgical procedures included (1) discectomy by inter-TP (transverse process) approach, (2) discectomy with partial facetectomy and (3) discectomy with facetectomy and PLIF (posterior lumbar interbody fusion). Among the 38 patients, there were 25 males and 13 females. The mean age was 58.4 years old. The herniated discs located at L(3-4) in 17, L(4-5) in 13, and 8 cases at L(5)S(1). Twenty-three patients were simple disc herniation, 15 cases with concomitant lumbar spinal stenosis. The symptoms and signs of exiting root compression at herniated disc level were presented in all patients and passing root compression presented in 7 Type I cases as well; while intermittent claudication being presented in 15 and low back pain in 21 patients. The VAS (visual analog pain scale) of radicular leg pain was taken before and after the operation. The postoperative outcomes were evaluated through the MacNab's method in all the patients.</p><p><b>RESULTS</b>By using the new classification system, the 38 patient were divided into Type I 10 cases, Type II 19 cases and Type III 9 cases. The adopted surgeries included discectomy by intertransverse approach in 5, discectomy with partial facetectomy in 7, and discectomy with facetectomy and PLIF in the rest 26 cases. The mean follow-up period was ranging from 6 months to 4 years and 10 months, average 2 years and 11 months. The mean VAS scores of radicular pain was 7.4 preoperatively, 2.7 at 2 weeks after the operation and 3.1 at final follow-up. The final clinical outcomes by MacNab's method were as follow: excellent results in 20 cases, good in 12, fair in 5 and poor in 1 case. The overall improvement ratio was 84.2%. The postoperative complications included superficial wound infection in 1 case, insufficient decompression in 1 case and leakage of cerebrospinal fluid in 1 case respectively. No breakage and loosening of internal fixation were detected.</p><p><b>CONCLUSIONS</b>A new clinical classification of far lateral lumbar disc herniation was suggested, which is significant to understanding the relevant pathology and choosing the surgical procedures.</p>

The therapeutic effect, main symptoms, body mass index (BMI), waist circumference (WC), hip circumference (HC), and WHR were investigated.</p><p><b>RESULTS</b>The total effective rate was 90.0% in the group A, significantly better than 78.6% in the group B (P< 0. 01), with significant differences in decrease of body weight, BMI, WC, HC and main symptoms between the two groups (P<0.05, P<0.01).</p><p><b>CONCLUSION</b>Acupuncture, cupping plus acupoint catgut embedding therapy can increase therapeutic effect on simple obesity of stomach and intestine excess-heat type, and it is a better method for treatment of this disease.</p>

Controlled study of needle warming therapy and electroacupuncture on simple obesity of spleen deficiency type / 中国针灸

<p><b>OBJECTIVE</b>To compare therapeutic effects of needle warming therapy and electroacupuncture on simple obesity with spleen deficiency.</p><p><b>METHODS</b>Sixty-eight cases of simple obesity with spleen deficiency, including water-dampness retention due to spleen deficiency, qi-deficiency of the lung and spleen, yang-deficiency of the spleen and kidney, were randomly divided into a needle warming therapy group (n = 36) and an electroacupuncture group (n = 32). Zhongwan(CV 12), Shuifen (CV 9), Qihai (CV 6), Zhongji (CV 3), Tianshu (ST 25), Shuidao (ST 28), and so on were selected as main acupoints in the both groups. Their therapeutic effects and body mass indexes were observed.</p><p><b>RESULTS</b>The total effective rate was 88.9% in the needle warming therapy group and 71.9% in the electroacupuncture group with a significant difference between the two groups (P < 0.05); and there was a significant difference between the two groups in decrease of body mass index (P < 0.05).</p><p><b>CONCLUSION</b>Needle warming therapy has definite and long-term therapeutic effect on simple obesity with spleen deficiency.</p>

Multi-sfice CT pulmonary function evaluation in emphysema / 中华放射学杂志

Objective To explore the feasibility of evaluating the lung function by MSCT in emphysema.Methods The MSCT scan and pulmonary function tests(PFF)were respectively performed in 147 receptors within one week.They were randomly divided into 2 groups:group A(120 receptors), including normal,mild,moderate and severe abnormal pulmonary function based on the PFT,for comparing the correlation between pulmonary quantitative indexes of MSCT pulmonary function and PFT and settingup the primary grade criteria of abnormal pulmonary function in emphysema,group B(27 receptors)for evaluating the diagnostic accuracy in group A.The total lung was respectively scanned at the full inspiration and full expiration with MSCT.The pulmonary quantitative indexes of MSCT were measured with Siemens Pulmo pulmonary quantitative software.Results There was correlation between pulmonary quantitative indexes of MSCT and PFF.The Piex/in_(-910)showed best correlation with FEV_1%(r=-0.905,P
