Abstract
Frailty syndrome denotes a decreased capacity of the body to maintain the homeostasis and stress of the internal environment, which simultaneously increases the risk of adverse health outcomes in older adults, including disability, hospitalization, falls, and death. To promote healthy aging, we should find strategies to cope with frailty. However, the pathogenesis of frailty syndrome is not yet clear. Recent studies have shown that the diversity, composition, and metabolites of gut microbiota significantly changed in older adults with frailty. In addition, several frailty symptoms were alleviated by adjusting gut microbiota with prebiotics, probiotics, and symbiosis. Therefore, we attempt to explore the pathogenesis of frailty syndrome in older people from gut microbiota and summarize the existing interventions for frailty syndrome targeting gut microbiota, with the aim of providing timely and necessary interventions and assistance for older adults with frailty.

Abstract
Neutrophil extracellular traps(NETs) are fibrous networks formed by neutrophils after a procedure called NETosis, with the function of capturing and killing pathogens. NETs are widely involved in the pathological processes of major diseases such as immune system diseases, respiratory diseases, metabolic diseases, cancers, and reperfusion injury. Therefore, regulating NETs has become one of the important ways to prevent and treat the above diseases. As an excellent traditional culture in China, traditional Chinese medicine has made outstanding contributions to the treatment of diseases. In recent years, studies have discovered that a variety of active components in traditional Chinese medicines, Chinese medicine compound prescriptions, and single traditional Chinese medicines can alleviate the symptoms by regulating NETs in the pathological process of major diseases. This article reviews the research progress in the regulation of NETs by the active components of traditional Chinese medicines, Chinese medicine compound prescriptions, and single traditional Chinese medicines in the last five years, aiming to serve as a reference for related research.

Abstract
Myocardial damage is the most serious pathological consequence of cardiovascular diseases and an important reason for their high mortality. In recent years, because of the high prevalence of systemic energy metabolism disorders (e.g., obesity, diabetes mellitus, and metabolic syndrome), complications of myocardial damage caused by these disorders have attracted widespread attention. Energy metabolism disorders are independent of traditional injury-related risk factors, such as ischemia, hypoxia, trauma, and infection. An imbalance of myocardial metabolic flexibility and myocardial energy depletion are usually the initial changes of myocardial injury caused by energy metabolism disorders, and abnormal morphology and functional destruction of the mitochondria are their important features. Specifically, mitochondria are the centers of energy metabolism, and recent evidence has shown that decreased mitochondrial function, caused by an imbalance in mitochondrial quality control, may play a key role in myocardial injury caused by energy metabolism disorders. Under chronic energy stress, mitochondria undergo pathological fission, while mitophagy, mitochondrial fusion, and biogenesis are inhibited, and mitochondrial protein balance and transfer are disturbed, resulting in the accumulation of nonfunctional and damaged mitochondria. Consequently, damaged mitochondria lead to myocardial energy depletion and the accumulation of large amounts of reactive oxygen species, further aggravating the imbalance in mitochondrial quality control and forming a vicious cycle. In addition, impaired mitochondria coordinate calcium homeostasis imbalance, and epigenetic alterations participate in the pathogenesis of myocardial damage. These pathological changes induce rapid progression of myocardial damage, eventually leading to heart failure or sudden cardiac death. To intervene more specifically in the myocardial damage caused by metabolic disorders, we need to understand the specific role of mitochondria in this context in detail. Accordingly, promising therapeutic strategies have been proposed. We also summarize the existing therapeutic strategies to provide a reference for clinical treatment and developing new therapies.

Abstract
AIM To develop a deep-learning model using contrast-enhanced chest computed tomography (CT) images to predict programmed death-ligand 1 (PD-L1) expression in patients with non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS Preoperative enhanced chest CT images and immunohistochemistry results for PD-L1 expression (<1% and ≥1% were defined as negative and positive, respectively) were collected retrospectively from 125 NSCLC patients to train and validate a deep-learning radiomics model (DLRM) for the prediction of PD-L1 expression in tumours. The DLRM was developed by combining the deep-learning signature (DLS) obtained from a convolutional neural network and clinicopathological factors. The indexes of the area under the curve (AUC), integrated discrimination improvement (IDI), and decision curve analysis (DCA) were used to evaluate the efficiency of the DLRM. RESULTS DLS and tumour stage were identified as independent predictors of PD-L1 expression by the DLRM. The AUCs of the DLRM were 0.804 (95% confidence interval: 0.697-0.911) and 0.804 (95% confidence interval: 0.679-0.929) in the training and validation cohorts, respectively. IDI analysis showed the DLRM had better diagnostic accuracy than DLS (0.0028 [p<0.05]) in the validation cohort. Additionally, DCA revealed that the DLRM had more net benefit than the DLS for clinical utility. CONCLUSION The proposed DLRM using enhanced chest CT images could function as a non-invasive diagnostic tool to differentiate PD-L1 expression in NSCLC patients.

Abstract
Objective: To examine the clinical value of rapid detection of drug-resistant bacteria by immunochromatography and the effects of rapid detection on the prognosis of patients with severe intra-abdominal infection complicated by carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection. Methods: This was a retrospective cohort study. We analyzed clinical data of 73 patients with severe abdominal infections with sepsis or septic shock complicated by CRE bloodstream infection admitted to the general surgery department of Jinling Hospital between February 2022 and February 2023. Patients were divided into a colloidal gold immunochromatographic assay (GICA) group (17 patients) and conventional testing group (56 patients) based on whether a GICA for CRE had been performed on the patients' first blood culture sample during the diagnosis and treatment process. There were no statistically significant differences between the GICA and conventional testing groups in age ([55.9±17.3] vs. [47.6±16.4] years), sex ([16 men vs. one woman ] vs. [41 men vs. 15 women]), median Charlson comorbidity index (3.0[2.0,4.0] vs. 3.0[2.0, 4.8]), septic shock (10 vs. 39), or acute kidney injury (8 vs. 40) (all P>0.05). Both groups routinely underwent traditional bacterial identification and drug susceptibility testing. Additionally, patients in the GICA group were tested directly for positive blood cultures using a GICA carbapenemase test kit. The main outcomes were mortality rates on Days 28 and 90 after the first identification of CRE bloodstream infection in both groups. We also compared the microbial clearance rate, duration of hospitalization and intensive care unit stay, and time from onset of CRE bloodstream infection to initiation of targeted and appropriate antibiotics between the two groups. Results: The rate of microbial clearance of bloodstream infection was significantly greater in the GICA group than in the conventional testing group (15/17 vs. 34/56 [60.7%], χ2=4.476, P=0.034), whereas the 28-day mortality tended to be lower in the GICA than conventional testing group [5/17 vs. 44.6% [25/56], χ2=1.250, P=0.264). The 90-day mortality (8/17 vs. 53.6% [30/56], χ2=0.222, P=0.638), median duration of hospitalization (37.0 [18.0, 46.5] days vs. 45.5 [32.2, 64.8] days, Z=-1.867, P=0.062), and median duration of intensive care unit stay (18.0 [6.5, 35.0] days vs. 32.0 [5.0, 51.8] days, Z=-1.251, P=0.209). The median time between the onset of bloodstream infection and administration of antibiotics was 49.0 (38.0, 69.0) hours in the GICA group, which is significantly shorter than the 163.0 (111.8, 190.0) hours in the conventional testing group (Z=-5.731, P<0.001). The median time between the onset of bloodstream infection and administration of appropriate antibiotics was 40.0 (34.0, 80.0) hours in the GICA group, which is shorter than in the conventional testing group (68.0 [38.2, 118.8]) hours; however, this difference is not statistically significant (Z=-1.686, P=0.093). Conclusions: GICA can provide information on carbapenemase- producing pathogens faster than traditional drug sensitivity testing, enabling early administration of the optimal antibiotics. The strategy of 'carbapenemase detection first' for managing bacterial infection has the potential to improve prognosis of patients and reduce mortality rate.

Abstract
Objective: The purpose of this study was to analyze the course and outcome of patients with combined entero-atmospheric fistulas in open abdomen treatment. Methods: In this retrospective observational study, we collected data on 214 patients with open abdomen complicated by entero-atmospheric fistulas admitted to Research Institute of General Surgery, Jinling Hospital, Affiliated Hospital of Medical School from January 2012 to January 2021. We collected their basic characteristics, aetiology, treatment plan, and prognosis, including the durations of hospitalization and open treatment, time to resumption of enteral nutrition, duration and prognosis of definitive surgery, and overall prognosis. Results: Of the 214 patients with open abdomen complicated with entero-enteral fistulas, 23 (10.7%) died (11 of multiple organ failure caused by abdominal infection, five of abdominal cavity bleeding, four of pulmonary infection, one of airway bleeding, one of necrotizing fasciitis, and one of traumatic brain injury). The remaining 191 underwent definitive surgery at our hospital. The patients who underwent definitive surgery were predominantly male (156 patients, 81.7%); their age was (46.5±2.5) years. Trauma and gastrointestinal tumors (120 cases, 62.8%) predominated among the primary causes. The reasons for abdominal opening were, in order, severe abdominal infection (137 cases, 71.7%, damage control surgery (29 cases, 15.2%), and abdominal hypertension (25 cases, 13.1%). Temporary abdominal closure measures were used to classify the participants into a skin-only suture group (104 cases) and a skin-implant group (87 cases). Compared with the skin-implant group, in the skin-suture-only group the proportion of male patients was lower (74.7% [65/87] vs. 87.5% [91/104], χ2=5.176, P=0.023), the mean age was older ([48.3±2.0] years vs. [45.0±1.9] years, t=-11.671, P<0.001), there were fewer patients with trauma (32.2% [28 /87] vs. 58.7% [61/104), χ2=13.337, P<0.001), intensive care stays were shorter ([8.9±1.0] days vs. [12.7±1.6] days, t=19.281, P<0.001), total length of stay was shorter ([29.3±2.0] days vs. [31.9±2.0] days, t=9.021,P<0.001), there was a higher percentage of colonic fistulas (18.4% [16/87] vs. 8.7% [9/104], χ2=3.948, P=0.047), but fewer multiple fistulas (11.5% [10/87] vs. 34.6% [36/104], χ2=14.440, P<0.001). As to fistula management, a higher percentage of fistula sealing methods using 3D-printed intestinal stents were implemented in the skin-only suture group (60.9% [53/87] versus 43.3% [45/104], χ2=5.907, P=0.015). Compared with the implant group, the skin-only suture group had a shorter mean time to performing provisional closure ( [9.5±0.8] days vs. [16.0±0.6] days, t=66.023, P<0.001), shorter intervals to definitive surgery ( [165.0±10.7] days vs. [198.9±8.3] days, t=26.644, P<0.001), and less use of biopatches (56.3% [49/87) vs. 71.2% [74/104], χ2=4.545, P=0.033). Conclusions: Open abdomen complicated with entero-enteral fistulas is more common in male, and is often caused by trauma and gastrointestinal tumor. Severe intra-abdominal infection is the major cause of open abdomen, and most fistulae involves the small intestine. Collection and retraction of intestinal fluid and 3D-printed entero-enteral fistula stent sealing followed by implantation and skin-only suturing is an effective means of managing entero-enteral fistulas complicating open abdominal cavity. Earlier closure of the abdominal cavity with skin-only sutures can shorten the time to definitive surgery and reduce the rate of utilization of biopatches.

Abstract
There is a consensus that selectively perform splenic lymph node dissection is necessary for high-risk patients with proximal gastric cancer to achieve radical treatment. However, there are still some outstanding issues that need to be solved during the practice of splenic lymph node dissection. These include poorly defined boundaries, technical difficulties, and blurred boundaries in No. 10 and No. 11 lymph nodes, etc. Membrane anatomy has achieved successful applications in the field of gastric and colorectal surgery in recent years. The study of membrane anatomy in the splenic hilum region is controversial due to the special location of the splenic hilum, which involves multiple organs and affiliated mesentery undergoing complex rotation, folding, and fusion during embryonic development. In this manuscript, we summarize the following points based on existing research and personal experience regarding membrane anatomy. 1. There is a membrane anatomical structure that can be used for lymph node dissection in the splenic hilum region. 2. The membrane structure in the splenic hilum region can be divided into two layers: the superficial layer is composed of the dorsal mesogastrium, and the deep layer is composed of Gerota fascia, the tail of the pancreas, and the mesentery of the transverse colon (from head to tail). 3. There is a loose space between the two layers that can be used for separation during surgery. The resection of the dorsal mesogastrium belongs to D2 dissection. The No. 10 lymph node in the deeper layer belongs to the duodenal mesentery, and the resection of the No.10 lymph node exceeds D2 dissection. The complete excision of the gastric dorsal mesentery is consistent with the D2+CME surgical mode proposed by Gong Jianping's group.

Abstract
Objective: To analyze the clinical significance of laboratory examination indicators as the key prognostic factors and to construct an early prediction model for prognosis assessment of pulmonary tuberculosis patients. Methods: The basic information, biochemical indexes and blood routine items of 163 tuberculosis patients (144 males and 19 females, aged 41-70 years, with an average age of 56 years) and 118 healthy persons who underwent physical examination (101 males and 17 females, aged 46-64 years, with an average age of 54 years) in Suzhou Fifth People's Hospital from January 2012 to December 2020 were retrospectively collected. According to the presence of Mycobacterium tuberculosis after six months of treatment, the enrolled patients were divided into a cured group (96 cases) and a treatment failure group (67 cases). To analyze the baseline levels of laboratory examination indicators between these two groups, we screened the key predictors and the binary logistic regression method in SPSS statistics software was used to construct the prediction model. Results: The baseline levels of total protein, albumin, prealbumin, glutamic-pyruvic transaminase, erythrocyte, hemoglobin and lymphocyte were significantly higher in the cured group than in the treatment failure group. After 6 months of treatment, the indexes of total protein, albumin and prealbumin increased significantly in the cured group, but remained at the low levels in the treatment failure group. Receiver operating characteristic (ROC) curve analysis showed that total protein, albumin and prealbumin as independent predictors for forecasting the prognosis of pulmonary tuberculosis patients had the highest prediction accuracy. Logistic regression analysis showed that the combination of these three key predictors could construct the best early prediction model for assessing the prognosis of pulmonary tuberculosis patients, with a prediction accuracy of 0.924 (0.886-0.961), sensitivity of 75.0%, specificity of 94%, showing an ideal prediction accuracy. Conclusions: The routine test indexes of total protein, albumin and prealbumin show good application value in the construction of early prediction model for prognosis evaluation of pulmonary tuberculosis treatment. The combined prediction model consisting of total protein, albumin and prealbumin is expected to provide a theoretical basis and reference model for precision treatment and prognosis assessment of tuberculosis patients.

Abstract
Objective: To analyze the levels and distribution characteristics of blood cadmium and urinary cadmium in American adults, to analyze the relationship between blood cadmium and urinary cadmium and pulmonary function dose response, and to explore the effect of this index on the risk of chronic obstructive pulmonary disease. Methods: In March 2022, 3785 patients from 2007 to 2012 in NHANES database were selected as the subjects. Collect demography data such as gender and age, and test data such as lung function, blood cadmium concentration and Urine cadimium concentration. The relationship between blood and urine cadmium levels and lung function and pulmonary function and chronic obstructive pulmonary diease (COPD) was analyzed by Mann-Whitney U test or Kruskal-Wallis H test, multivariate linear regression and restricted cubic spline method. Results: The geometric mean of blood cadmium and urine cadmium in American adults was 0.37 g/L and 0.28 g/L, FEV(1) and FEV(1)/FVC among different cadmium exposure groups was statistically significant, and there was a negative linear dose-response relationship between serum Cd and urine Cd concentrations and FEV(1)/FVC levels (P(overall)<0.001, P(non-linear)=0.152; P(overall)<0.001, P(non-linear)=0.926). Compared with the lowest quartile concentration (Q1), the highest quartile blood cadmium concentration (Q4) (OR=1.934, P(trend)=0.000) and urinary cadmium concentration (OR=1.683, P(trend)=0.000) may increased the risk of chronic obstructive pulmonary disease. Conclusion: There is a negative correlation between blood cadmium, urinary cadmium levels and lung function in American adults, and cadmium may increase the risk of chronic obstructive pulmonary disease.

Abstract
Cancer cachexia is a metabolic syndrome that is characterized by progressive loss of skeletal muscle mass, and effective therapeutics have yet to be developed. Saikosaponin D (SSD), a major bioactive component of Radix Bupleuri, exhibits antiinflammatory, anti-tumor, anti-oxidant, anti-viral, and hepatoprotective effects. In this study, we demonstrated that SSD is a promising agent for the treatment of cancer cachexia. SSD could alleviate TCM-induced myotube atrophy and inhibit the expression of E3 ubiquitin ligases muscle RING-finger containing protein-1 (MuRF1) and muscle atrophy Fbox protein (Atrogin-1/MAFbx) in vitro. Moreover, SSD suppressed the progression of cancer cachexia, with significant improvements in the loss of body weight, gastrocnemius muscle, and tibialis anterior muscle mass in vivo. Mechanism investigations demonstrated that SSD could directly bind to STAT3 and specifically inhibit its phosphorylation as well as its transcriptional activity. Overexpression of STAT3 partially abolished the inhibitory effect of SSD on myotube atrophy, indicating that the therapeutic effect of SSD was attributed to STAT3 inhibition. These findings provide novel strategies for treatment of cancer cachexia by targeting STAT3, and SSD may be a promising drug candidate for cancer cachexia.

Abstract
Hepatic fibrosis is a pathological change caused by chronic liver injury and self-repair, and it is the inevitable stage of the development of chronic liver disease to cirrhosis or even liver cancer. Activation of hepatic stellate cells (HSCs) is a core event in the development of liver fibrosis and blockage of the activation of HSCs has been shown to alleviate liver fibrosis. Roxarsone, an organoarsenic additive, with antibiotic effect, growth promotion and improving feed efficiency, is widely used in livestock and animal production. The purpose of this study was to evaluate the therapeutic effect of Roxarsone on liver fibrosis and explore the possible mechanism. We found that Roxarsone could inhibit transforming growth factor-β1 (TGF-β1) induced the activation of HSCs and weaken the migration ability. Moreover, Roxarsone administration significantly ameliorated CCl4-induced liver fibrosis in mice with improvement of liver function and decreases of deposition of extracellular matrix (ECM). Mechanism investigations revealed that Roxarsone specifically inhibited the activation of TGF-β1/Smad signaling pathway, but had no effect on MAPK and PI3K/AKT pathways. These results suggest that Roxarsone has a protective effect on liver fibrosis which provides a new candidate for the treatment of liver fibrosis.

Abstract
Objective: To investigate the regulatory effects of bio-intensity electric field on directional migration and microtubule acetylation in human epidermal cell line HaCaT, aiming to provide molecular theoretical basis for the clinical treatment of wound repair. Methods: The experimental research methods were used. HaCaT cells were collected and divided into simulated electric field group (n=54) placed in the electric field device without electricity for 3 h and electric field treatment group (n=52) treated with 200 mV/mm electric field for 3 h (the same treatment methods below). The cell movement direction was observed in the living cell workstation and the movement velocity, trajectory velocity, and direction of cosθ of cell movement within 3 h of treatment were calculated. HaCaT cells were divided into simulated electric field group and electric field treatment 1 h group, electric field treatment 2 h group, and electric field treatment 3 h group which were treated with 200 mV/mm electric field for corresponding time. HaCaT cells were divided into simulated electric field group and 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group treated with electric field of corresponding intensities for 3 h. The protein expression of acetylated α-tubulin was detected by Western blotting (n=3). HaCaT cells were divided into simulated electric field group and electric field treatment group, and the protein expression of acetylated α-tubulin was detected and located by immunofluorescence method (n=3). Data were statistically analyzed with Kruskal-Wallis H test,Mann-Whitney U test, Bonferroni correction, one-way analysis of variance, least significant difference test, and independent sample t test. Results: Within 3 h of treatment, compared with that in simulated electric field group, the cells in electric field treatment group had obvious tendency to move directionally, the movement velocity and trajectory velocity were increased significantly (with Z values of -8.53 and -2.05, respectively, P<0.05 or P<0.01), and the directionality was significantly enhanced (Z=-8.65, P<0.01). Compared with (0.80±0.14) in simulated electric field group, the protein expressions of acetylated α-tubulin in electric field treatment 1 h group (1.50±0.08) and electric field treatment 2 h group (1.89±0.06) were not changed obviously (P>0.05), while the protein expression of acetylated α-tubulin of cells in electric field treatment 3 h group (3.37±0.36) was increased significantly (Z=-3.06, P<0.05). After treatment for 3 h, the protein expressions of acetylated α-tubulin of cells in 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group were 1.63±0.05, 2.24±0.08, and 2.00±0.13, respectively, which were significantly more than 0.95±0.27 in simulated electric field group (P<0.01). Compared with that in 100 mV/mm electric field group, the protein expressions of acetylated α-tubulin in 200 mV/mm electric field group and 300 mV/mm electric field group were increased significantly (P<0.01); the protein expression of acetylated α-tubulin of cells in 300 mV/mm electric field group was significantly lower than that in 200 mV/mm electric field group (P<0.05). After treatment for 3 h, compared with that in simulated electric field group, the acetylated α-tubulin of cells had enhanced directional distribution and higher protein expression (t=5.78, P<0.01). Conclusions: Bio-intensity electric field can induce the directional migration of HaCaT cells and obviously up-regulate the level of α-ubulin acetylation after treatment at 200 mV/mm bio-intensity electric field for 3 h.

Abstract
Appropriate and effective recycling of food waste (FW) has become increasingly significant with the promotion of garbage classification in China. In this study, a novel and green process was developed to recycle FW to prepare a biodegradable composite liquid mulching film (LMF) through crosslinking with sodium alginate (SA). The solid phase of FW was obtained as the raw material after hydrothermal pretreatment to remove pathogens and salts, and to improve the reactivity of active components at a moderate temperature. The prepared LMF had a hydrophobic surface and compact structure due to the lipid in FW and the acetalization reaction and hydrogen bonds among SA, glutaraldehyde and multi-active components of FW, resulting in enhanced water vapor barrier properties. The minimum water vapor permeability of the prepared LMF reached (8.23 ± 0.05) ✕ 10-12 g cm/(cm2·s·Pa) with 1.82 wt % of plasticizer, 0.74 wt% of crosslinker and a mass ratio of HTP-FW to SA of 3.56:1. The prepared LMF showed good mechanical properties and could maintain its integrity after spraying it on the soil surface for 31 days. In addition, it could effectively prevent the loss of soil moisture and heat, promote the seed germination of Chinese cabbage and achieve 89.14% of weight loss after burying in the soil for 27 days. This study provides a high value-added route to convert the FW to a hydrophobic LMF with superior properties, which addresses not only the problem of food waste but also the pollution of plastic mulching film.

Abstract
Inflammatory bowel disease (IBD) is a non-specific chronic intestinal inflammatory disease, often presenting with abdominal pain, diarrhea, bloody stool, anorexia, and body loss. It is difficult to cure completely and a promising treatment is urgently needed. Natural compounds can offer promising chemical agents for treatment of diseases. Polydatin is a natural ingredient extracted from the dried rhizome of Polygonum cuspidatum, which has anti-inflammatory, anti-tumor, and dementia protection activities. The purpose of this study was to evaluate the therapeutic effect of polydatin on IBD and explore its possible mechanism. We found that polydatin could effectively suppress the differentiation of Th17 cells in vitro, but had no effect on the differentiation of Treg cells. Polydatin significantly alleviated colitis induced by dextran sulfate sodium (DSS) and 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) in mice, and dramatically decreased the proportion of Th17 cells in spleen and mesenteric lymph nodes. Mechanism investigations revealed that polydatin specifically inhibited signal transducer and activator of transcription 3 (STAT3) phosphorylation by directly binding to STAT3, leading to Th17 cell reduction and thereby alleviating colitis. These findings provide novel insights into the anti-colitis effect of polydatin, which may be a promising drug candidate for the treatment of IBD.

Abstract
OBJECTIVE To compare the curative effect of panlong needling at Jiaji (EX-B 2) combined with western medication and western medication alone on motor dysfunction in patients with Parkinson's disease (PD) of liver and kidney deficiency. METHODS A total of 98 patients with PD were randomly divided into an acupuncture and medication group (49 cases, 1 case dropped off) and a western medication group (49 cases,1 case was removed). The patients in the western medication group were given oral of levodopa and benserazide hydrochloride tablets, 125 mg each time, three times a day in the 1st week, and the dose was increased according to the needs of the patients' condition from the 2nd week until 250 mg each time, three times a day, for 16 consecutive weeks. On the basis of the same western medication treatment as the western medication group, panlong needling was applied at Jiaji (EX-B 2) from C2 to L5 in the acupuncture and medication group, once a day, 20 times as a course of treatment, for 4 consecutive courses. The scores of unified Parkinson's disease rating scale (UPDRS-Ⅲ, UPDRS-Ⅳ), TCM symptoms score, and 39-item Parkinson's disease questionnaire (PDQ-39) score were evaluated before treatment, after treatment and during follow-up of 1 month after treatment, respectively. The safety of the two groups was compared. RESULTS After treatment and during follow-up, except the PDQ-39 score of the western medication group, the scores of UPDRS-Ⅲ, UPDRS-Ⅳ, TCM syndrome and PDQ-39 were lower than those before treatment in the two groups (P<0.05), and the scores of above indexes in the acupuncture and medication group were lower than those of the western medication group (P<0.05). The total incidence of adverse reactions in the acupuncture and medication group was 10.4% (5/48), which was lower than 29.2% (14/48) in the western medication group (P<0.05). CONCLUSION Panlong needling at Jiaji (EX-B 2) combined with western medication could significantly improve the motor dysfunction and clinical symptoms, improve the quality of life and has high safety, and the efficacy is superior to western medication alone.

Abstract
Objective: The surgical reconstruction strategy for scar contracture deformity in chin and neck was explored, aiming to obtain better aesthetic outcome. Methods: A retrospective observational study was conducted. From December 2017 to April 2021, 34 patients with scar contracture deformity in chin and neck after burns were hospitalized in the Department of Plastic Surgery of the First Affiliated Hospital of Army Medical University (the Third Military Medical University), aged 12-54 years, including 13 males and 21 females, 4 cases with chin affected only, 7 cases with neck affected only, and 23 cases with both chin and neck affected. The scar areas were 48-252 cm2. All the patients were treated by operation with expanded flaps, following the "MRIS" principle of matching of the color and thickness of the repair flaps (match), reconstructing of the aesthetic features of subunits (reconstruction), design of incision according to the plastic principle (incision), and prevention of the surgical incision scar (scar). The rectangular or kidney shaped skin and soft tissue expander (hereinafter referred to as the expander) with rated capacity of 80-400 mL was embedded in the first stage, which was routinely expanded to 3-5 times of the rated capacity of the expander. In the second stage, scar resection and expanded flap excision were performed to repair the secondary wound, and the flap donor site was sutured directly. The expansion ratio of the expander (with average value being calculated), the type of flaps used, the reconstruction of local aesthetic morphology, the appearance of postoperative incision, the survival of flap, and the situation of donor and recipient sites observed during follow-up were recorded. Results: Among the 34 patients, the average expansion ratio of the implanted expander was 3.82 times of the rated capacity of the expander. Three cases were repaired by the expanded local pedicled flap only, 19 cases by the expanded shoulder and/or chest perforator pedicled flap only, 10 cases by the expanded local pedicled flap combined with the expanded shoulder and/or chest perforator pedicled flap, and 2 cases by the expanded local pedicled flap combined with the expanded free flap of the second intercostal perforator of internal thoracic artery. After scar resection, the shapes of lower lip and chin-lip groove were reconstructed in 10 cases, chin process reconstruction and chin lengthening were performed in 16 cases, and the cervico-mental angle and mandibular margin contour were reconstructed in 28 cases. The surgical incision was concealed, most of which were located at the natural junction or turning point of the chin and neck subunits. The vertical incision of neck was Z-shaped or fishtail-shaped. All the expanded flaps in 34 patients survived after operation, of which 8 patients had minor necrosis at the edge or tip of the expanded flaps 1-3 days after operation and healed after dressing change. During the follow-up of 3-18 months, little difference in color and thickness between the expanded flap and the skin of chin and neck was observed, and the aesthetic shape of chin and neck was significantly improved, with mild scar hyperplasia of surgical incision. Conclusions: Reconstruction of scar contracture deformity in chin and neck by using expanded flaps based on the "MRIS" principle is beneficial to improve the quality of surgery and achieve better aesthetic outcome.

Abstract
Astrocytes (AST) play an important role in the pathogenesis of neurological disorders, and their activation is involved in the progression of multiple sclerosis (MS). (6aS, 10S, 11aR, 11bR, 11cS)-10-methylaminododecahydro-3a, 7a-diaza-benzo (de) anthracene-8-thione (MASM), a novel derivative of matrine, exhibits vast pharmacological activities, such as anti-tumor, anti-fibrosis and immune regulation. In this study, we demonstrate that MASM is a promising agent for the treatment of experimental autoimmune encephalomyelitis (EAE). MASM not only inhibited inflammatory responses in LPS-stimulated astrocytes, but also suppressed the formation of reactive A1 astrocyte and maintained astrocytic functions, including the ability to promote synapse formation and phagocytose synapses and myelin debris. Importantly, MASM could significantly alleviate the development of EAE, with significant inhibition of inflammation, demyelination, axon loss and the body weight loss. Meanwhile, MASM also inhibited the activation of astrocytes and improved the function of BBB in vivo. These findings provide novel insights into the protective effect of MASM on EAE, which may be a promising drug candidate for treatment of EAE.

Abstract
OBJECTIVE To systematically evaluate the efficacy of Shengmai San in patients with cardiotoxicity of anthracyclines. METHODS Randomized controlled trials (RCTs) were identified by searching China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), PubMed, Cochrane Library, and Embase Databases from the inceptions until December 2020. The Cochrane Handbook was used to evaluate the risk of bias in the included studies. Data analysis was conducted using RevMan 5.3 software. RESULTS Totally 19 RCTs with 2,331 participants were included in this review. Results showed that in improving arrhythmia (13 RCTs, n=1,877, RR=0.37, 95%CI 0.25 to 0.52, P<0.00001), the treatment group was superior to the control group. In terms of reducing left ventricular end-diastolic diameter (LVEDD, 2 RCTs, n=128, MD=-0.79, 95%CI -0.93 to -0.65, P<0.00001) and left ventricular end systolic diameter (LVESD, 2 RCTs, n=128, MD=-0.58, 95%CI -0.82 to -0.35, P<0.00001), the treatment group was also better than the control group. In reducing myocardial enzymes such as creatine kinase (CK) [(3 RCTs, n=256, SMD=-0.80, 95%CI -1.16 to -0.44, P<0.0001), (2 RCTs, n=126, SMD=-0.62, 95%CI -0.98 to -0.26, P=0.0007)], the treatment group was superior to the control group. CONCLUSION Shengmai San has a positive effect on the treatment of cardiotoxicity from anthracyclines. However, in the future, it is still necessary to conduct high-quality RCTs to verify its efficacy.

Abstract
Objective: To analyze the changes on gut microbiota and metabolic products in patients with chronic heart failure. Methods: By searching the Pubmed, EMBASE, Cochrane Library, and CNKI, Wanfang, and CMB databases from the day of built up to December 2019, we screened related literature exploring the intestinal flora of chronic heart failure patients, and systematic review was performed to study changes in intestinal flora composition, function, and metabolites among chronic heart failure patients. Results: A total of 10 articles were included to study the gut microbiota of patients with chronic heart failure in this analysis. The systematic review showed significant changes in β-diversity in patients with heart failure. The abundance of faecalibacterium, blautia, bacteroides, prevotella and anaerostipes was decreased, while the abundance of streptococcus, escherichia/shigella, veillonella, and enterobacte was increased. The increased microbial gene function in patients with heart failure included tryptophan metabolism, lipid metabolism, LPS synthesis,and so on, especially, bacterial genes related to trimethylamine oxide production increased significantly, while genes related to key enzymes producing the beneficial metabolite butyrate decreased significantly, and harmful metabolite trimethylamine oxide levels increased in chronic heart failure patients. Conclusion: There are significant changes in the structure, function and metabolites of intestinal flora in patients with chronic heart failure.

Abstract
Objective: To explore the effects and possible molecular mechanism of histone deacetylase 6 (HDAC6) inhibitor Tubastatin A on the proliferation and movement of human skin fibroblasts (HSFs). Methods: The experimental research method was used. HSFs in logarithmic growth phase were taken and divided into negative control group, 1 μmol/L Tubastatin A group, 5 μmol/L Tubastatin A group, and 10 μmol/L Tubastatin A group according to the random number table. The HSFs in negative control group were added with Dulbecco's modified eagle medium with the final volume fraction of 0.1% dimethyl sulfoxide (hereinafter referred to as the complete medium), and the other three groups were added with the complete medium with the corresponding final molarity of Tubastatin A. After 24 h of conventional culture, the cell proliferation activity was detected using cell counting kit 8 (CCK-8) method and 5-ethynyl-2'-deoxyuridine (EdU) staining; the range of motion of cells within 3 h was observed under the living cell workstation, and the curve movement velocity of the cells was calculated. The protein expressions of extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated ERK1/2 (p-ERK1/2) were detected by Western blotting, and the ratio of p-ERK1/2 to ERK1/2 was calculated to represent the activity of ERK1/2. The sample number in cell proliferation activity detection with CCK-8 method was 6, while the sample numbers in other experiments were 3. Data were statistically analyzed with one-way analysis of variance and least significant difference test. Results: After 24 h of culture, CCK-8 method and EdU staining showed that compared with negative control group, the cell proliferation activities in 1 μmol/L Tubastatin A group, 5 μmol/L Tubastatin A group, and 10 μmol/L Tubastatin A group were significantly decreased (P<0.01). After 24 h of culture, CCK-8 method showed that compared with 1 μmol/L Tubastatin A group, the cell proliferation activity in 10 μmol/L Tubastatin A group was significantly decreased (P<0.05); EdU staining showed that compared with 1 μmol/L Tubastatin A group, the cell proliferation activities in 5 μmol/L Tubastatin A group and 10 μmol/L Tubastatin A group were significantly decreased (P<0.05 or P<0.01). Within 3 h of observation, the ranges of cell motion in 1 μmol/L Tubastatin A group, 5 μmol/L Tubastatin A group, and 10 μmol/L Tubastatin A group were obviously reduced compared with that in negative control group. Within 3 h of observation, the curve movement velocity of cells in negative control group was (0.780±0.028) μm/min, which was obviously faster than (0.594±0.023), (0.469±0.028), and (0.391±0.021) μm/min of 1 μmol/L Tubastatin A group, 5 μmol/L Tubastatin A group, and 10 μmol/L Tubastatin A group (P<0.01); the curve movement velocity of cells in 1 μmol/L Tubastatin A group was obviously faster than those in 5 μmol/L Tubastatin A group and 10 μmol/L Tubastatin A group (P<0.01); the curve movement velocity of cells in 5 μmol/L Tubastatin A group was obviously faster than that in 10 μmol/L Tubastatin A group (P<0.05). After 24 h of culture, compared with negative control group, the activities of ERK1/2 of cells in 1 μmol/L Tubastatin A group, 5 μmol/L Tubastatin A group, and 10 μmol/L Tubastatin A group were decreased significantly (P<0.01); compared with 1 μmol/L Tubastatin A group, the activities of ERK1/2 of cells in 5 μmol/L Tubastatin A group and 10 μmol/L Tubastatin A group were decreased significantly (P<0.01); compared with 5 μmol/L Tubastatin A group, the activity of ERK1/2 of cells in 10 μmol/L Tubastatin A group was decreased significantly (P<0.05). Conclusions: HDAC6 inhibitor Tubastatin A may mediate the inhibitory effect on proliferation and movement of HSFs by inhibiting the activity of ERK1/2.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Si-Miao-Yong-An decoction (SMYAD) is a renowned traditional Chinese medicinal formula. SMYAD was originally recorded in the "Shi Shi Mi Lu", which was edited by medical scientist Chen Shi'duo during the Qing Dynasty. SMYAD has been traditionally used to treat thromboangiitis obliterans. At present, it is mainly used in clinical applications and research of cardiovascular diseases. AIM OF THE STUDY To explore the effects of SMYAD on the pathological changes of atherosclerosis (AS) and the differentiation of monocytes, macrophages, and regulatory T (Treg) cells in apolipoprotein E knockout (ApoE-/-) mice. MATERIALS AND METHODS Eight C57BL/6J mice, which were fed with normal diet for 16 weeks, were used as control group. Forty ApoE-/- mice were randomly divided into model group, atorvastatin group, SMYAD low-dose (SMYAD-LD) group, SMYAD medium-dose (SMYAD-MD) group, and SMYAD high-dose (SMYAD-HD) group. ApoE-/- mice were fed with western diet (WD) for 8 weeks, and the drugs were continuously administered for 8 weeks. The levels of serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured by the esterase method. Morphological changes of the aortic sinus in mice were observed by hematoxylin-eosin (HE) staining, the lipid infiltration of the aorta and aortic sinus were observed by oil red O staining, and the spleen index was calculated. The proportion of Ly6Chigh and Ly6Clow monocyte subsets, macrophages, and their M1 phenotype, as well as Treg cells in spleen were measured by flow cytometry. The expressions of cluster of differentiation 36 (CD36), scavenger receptor A1 (SRA1), lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), F4/80, and fork head frame protein 3 (FOXP3) in aortic sinus were assessed by immunohistochemical staining. The serum levels of oxidized low density lipoprotein (ox-LDL), interleukin-1β (IL-1β), IL-18, transforming growth factor-β (TGF-β), and IL-10 were measured by enzyme-linked immunosorbent assays (ELISA). RESULTS Compared with the model group, the level of serum TC and LDL-C decreased in the SMYAD group, the pathological changes of aortic sinus decreased, and lipid infiltration of aorta and aortic sinus also decreased. These decreases were accompanied by a significant downregulation of CD36, SRA1, and LOX-1. Furthermore, the proportions of Ly6Chigh pro-inflammatory monocyte subsets, macrophages, and their M1 phenotypes in spleen decreased significantly, while the proportion of Treg cells increased. In addition, while the expression of F4/80 decreased, the expression of FOXP3 increased in the aorta sinus. The levels of serum pro-inflammatory factors IL-1β and IL-18 decreased. CONCLUSIONS SMYAD can improve the pathological changes associated with AS and can inhibit lipid deposition in ApoE-/- mice induced by WD diet. The likely mechanism is the inhibition of the differentiation and recruitment of monocytes and macrophages, the promotion of the differentiation and recruitment of Treg cells, as well as the reduction of the secretion of pro-inflammatory factors.

Abstract
Objective: To understand the epidemiological and genotypic characteristics of imported cases of measles virus of D8 genotype in Hebei province. Methods: Epidemiological investigation of measles cases in surveillance was carried out. The throat swabs of the measles cases in acute phase were collected for real time RT-PCR identification, measles virus culture and genotype identification. Results: A total of 36 imported measles cases of genotype D8 were detected. The cases were mainly distributed in 8 counties of Handan city. Number of confirmed measles cases in Cheng'an county was the highest, accounting for 58.33% (21/36) of all the reported cases. All patients had fever and rash, and 55.55% (20/36) of the cases were under 2 years old and 86.11% (31/36) of the cases had no immunization history. The children with pneumonia accounted for 44.12% (15/34) of the total children with D8 genotype measles virus infection. The nucleotide and amino acid homologies between the imported measles virus genotype D8 and the WHO reference strain of D8 genotype (D8-Manchester.UNK/30.94) were 98.4%-98.6% and 97.3%, respectively. Compared with the strains of H1 genotype in China, the nucleotide and amino acid homologies were 92.8%-93.1% and 93.3%, respectively. Conclusions: The imported cases of measles virus of D8 genotype might have caused local transmission in Hebei province. Molecular epidemiological surveillance for measles virus needs to be further strengthened. It is necessary to detect and control the epidemic early and improve the coverage rate and timely rate of measles vaccination. It is also important to prevent cross infection in hospitals.

Abstract
BACKGROUND Citrin deficiency (CD) is an autosomal recessive disease resulting from biallelic mutations of the SLC25A13 gene. This study aimed to investigate the molecular epidemiological features of CD in the Guangdong and Shaanxi provinces of China. METHODS A total of 3,409 peripheral blood samples from Guangdong and 2,746 such samples from Shaanxi province were collected. Four prevalent SLC25A13 mutations NG_012247.2 (NM_014251.3): c.852_855del, c.1638_1660dup, c.615+5G>A, and c.1751-5_1751-4ins(2684) were screened by using the conventional polymerase chain reaction (PCR)/PCR-restriction fragment length polymorphism and newly-developed multiplex PCR methods, respectively. The mutated SLC25A13 allele frequencies, carrier frequencies, and CD morbidity rates were calculated and then compared with the Chi-square and Fisher's exact tests. RESULTS The mutations were detected in 68 out of 6,818 SLC25A13 alleles in Guangdong and 29 out of 5,492 alleles in the Shaanxi population. The carrier frequencies were subsequently calculated to be 1/51 and 1/95, while the CD morbidity rates were 1/10,053 and 1/35,865, in the 2 populations, respectively. When compared with the Shaanxi population, Guangdong exhibited a higher frequency of mutated SLC25A13 allele (68/6,818 vs. 29/5,492, χ2=8.570, P=0.003) in general, with higher c.852_855del (54/6,818 vs. 13/5,492, χ2=17.328, P=0.000) but lower c.1751-5_1751 -4ins(2684) (2/6,818 vs. 9/5,492, P=0.015) allele frequencies. The distribution of c.615+5G>A and c.1638_1660dup between the 2 provinces, as well as all 4 prevalent mutations among different geographic regions within the 2 provinces, did not differed significantly. CONCLUSIONS Our findings depicted the CD molecular epidemiological features in Guangdong and Shaanxi populations, providing preliminary but significant laboratory evidences for the subsequent CD diagnosis and management in the 2 provinces of mainland China.

Abstract
Objective: To investigate the safety and feasibility of transgluteal percutaneous drainage using double catheterization cannula in the treatment of deep pelvic abscess. Methods: A retrospective analysis of the clinical data of patients who underwent transgluteal percutaneous drainage using double catheterization cannula with deep pelvic abscesses admitted to the Jinling Hospital from May 2017 to September 2020 was conducted. Seven patients were enrolled, including 5 males and 2 females, who aged 26-74 (median 53.0) years old, and all of them had digestive fistula. One male patient was punctured again due to the tube falling off, and a total of 7 patients underwent 8 times of transgluteal percutaneous drainage, all under the guidance of CT. The puncture and drainage steps of the double catheterization cannula group are as follows: (1) Locate the puncture point under CT in the lateral position; (2) Place the trocar into the abscess cavity; (3) Confirm that the trocar is located in the abscess cavity under CT; (4) Pull out the inner core and insert into the double catheterization cannula through the operating hole; (5) Confirmthat the double catheterization cannula is located in the abscess cavity under CT; (6) The double catheterization cannula is properly fixed to prevent it from falling off. The white blood cells, C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6) of all patients before the drainage and 1 days, 3 days, and 5 days after the drainage were collected, as well as the bacterial culture results of the drainage fluid. The changes of various infection biomarkers before and after the drainage were compared. Results: All 7 patients were cured. No complications such as hemorrhage and severe pain were observed. The average time with drainage tube was 60.8 (18-126) days. Five patients finally underwent gastrointestinal reconstruction surgery due to gastrointestinal fistula. The median serum interleukin-6 of patients before drainage, 1 day, 3 days and 5 days after drainage were 181.6 (113.0, 405.4) μg/L, 122.2 (55.8, 226.0) μg/L, 59.2 (29.0,203.5) μg/L and 64.1 (30.0,88.4) μg/L, respectively.The level of serum interleukin-6 at 3 days and 5 days after drainage was significantly lower than before drainage (F=3.586, P=0.026). Although the white blood cell count, C-reactive protein, and procalcitonin decreased gradually after drainage compared with before drainage, the difference was not statistically significant (all P>0.05). Conclusion: Transgluteal percutaneous drainage with double catheterization cannula is simple and effective, and can be used for the treatment of deep pelvic abscess.

Abstract
Macrophages have been reported to participate in inflammation, tissue homeostasis and tissue repair. The detailed mechanism of macrophage-mediated tissue repair is not clear. CXCL-10, secreted by monocytes, endothelial cells and fibroblasts, mediates immune response and angiogenesis by binding to CXCR3. In this study, the expression of CXCL-10 and CXCR3 in porcine lung injury induced by porcine reproductive and respiratory syndrome virus (PRRSV) infection was firstly examined. The results showed that the expression of both CXCL-10 and CXCR3 increased in the infected pig lungs. In addition, the increased expression of CXCL-10 and CXCR3 in macrophage treated by poly (I:C) was also observed, suggesting the autocrine system existed in macrophages. Furthermore, CXCL-10 treatment induced upregulation of Arg1 and VEGFa, and downregulation of TNFα in macrophage, and CXCR3 antagonist AMG487 treatment presented the contrary effects on the expression of Arg1, VEGFa, and TNFα. CXCL- 10-stimulated effects were dependent on PI3K/Akt signaling pathway. Wound-healing assay showed that CXCL-10 treatment macrophage conditioned medium promoted the healing process of endothelial cells. Our results suggested that CXCL-10/CXCR3 in macrophage may mediate tissue repair by regulating the macrophage expression of Arg1, VEGFa and TNFα. Modulation of CXCL-10/CXCR3 axis in macrophage may be a potential therapeutic strategy for tissue injury and repair.

Abstract
Different from classical surgical anatomy which only pays attention to the morphology and structure of human organs, modern membrane anatomy focuses on not only the relationship between morphology and structure, but also the biological behavior characteristics of tumors. Membrane antomy is a theoretical system with interpretation on both the structural and disease function, so it has been accepted by more and more gastrointestinal surgeons. However, the theoretical system of gastric membrane anatomy is not mature yet. The stomach and its mesentery have undergone complex rotation and fusion in the process of embryonic development, so that surgeons have different understandings of the gastric membrane anatomy. Therefore, it is easy to cause various confusion and misunderstanding, resulting in deviations between the theory of membrane anatomy and the practice of surgery. In the present study, the mesentery of the stomach is divided into different regions, and the embryonic development process is traced back. The application and compromise encountered in the radical gastrectomy of gastric cancer will be expounded according to the membrane anatomy theory combined with the author's experience of operation.

Abstract
BACKGROUND Transcranial direct current stimulation (tDCS) is a non-invasive brain modulation technique that has been proved to exert beneficial effects in the acute phase of stroke. To explore the underlying mechanism, we investigated the neuroprotective effects of cathodal tDCS on brain injury caused by middle cerebral artery occlusion (MCAO). RESULTS We established the MCAO model and sham MCAO model with an epicranial electrode implanted adult male Sprague-Dawley rats, and then they were randomly divided into four groups (MCAO + tDCS, MCAO + sham tDCS (Sham), Control + tDCS and Control + Sham group). In this study, the severity degree of neurological deficit, the morphology of brain damage, the apoptosis, the level of neuron-specific enolase and inflammatory factors, the activation of glial cells was detected. The results showed that cathodal tDCS significantly improved the level of neurological deficit and the brain morphology, reduced the brain damage area and apoptotic index, and increased the number of Nissl body in MCAO rats, compared with MCAO + Sham group. Meanwhile, the high level of NSE, inflammatory factors, Caspase 3 and Bax/Bcl2 ratio in MCAO rats was reduced by cathodal tDCS. Additionally, cathodal tDCS inhibited the activation of astrocyte and microglia induced by MCAO. No difference was found in two Control groups. CONCLUSION Our results suggested that cathodal tDCS could accelerate the recovery of neurologic deficit and brain damage caused by MCAO. The inhibition of neuroinflammation and apoptosis resulted from cathodal tDCS may be involved in the neuroprotective process.

Abstract
Objective: To investigate the effect of PR domain zinc finger protein 9 (PRDM9), one of the histone methylated transferases, on osteogenic differentiation ability of periodontal ligament mesenchymal stem cells (PDLSC). Methods: PDLSC with PRDM9 gene knocked down by PRDM9 shRNA using recombinant lentiviral vector were allocated into the PRDM9sh group, and the transfected shRNA was as the control group. The gene expression efficiency was evaluated by reverse transcription polymerase chain reaction (RT-PCR). Alkaline phosphatase activity (ALP), alizarin red staining, mineralization and osteocalcin, which belongs to osteogenic differentiation markers detected by RT-PCR and Western blotting to detect the osteogenic differentiation ability of stem cells from periodontal ligaments in vitro. In vivo, PRDM9sh and control group cells was transplanted into the dorsal dermal to explore the osteogenesis. The area percentage of new osteogenic tissue was calculated by image pro software and statistically analyzed. Results: RT-PCR results showed that the relative expression of PRDM9 gene in PRDM9sh (0.460±0.017) was significantly lower than that in control group (1.000±0.107) (P<0.05). The results of ALP activity determined at 5 days postinduction in a significant decrease in PRDM9sh cells (0.762±0.063) compared with control group (1.225±0.058) (P<0.01). Alizarin red staining induced by osteogenesis at 2 weeks and 3 weeks showed that the staining of PRDM9sh was significantly lighter than that in control group. Quantitative calcium analysis results showed that the calcium ion concentration induced by osteogenesis at 2 weeks and 3 weeks [(0.071±0.004), (0.075±0.001)] in PRDM9sh was significantly lower than that in control group at 2 weeks and 3 weeks [(0.282±0.006), (0.485+0.004)] (P<0.01). RT-PCR results showed that the relative expression of osteocalcin mRNA in PRDM9sh (1.059±0.148) was significantly lower than that in control group at 2 weeks (2.542±0.190) (P<0.01). Western blotting results showed that osteocalcin expression in PRDM9sh was significantly lower than that in control group at 1 and 2 weeks after osteogenesis induction. Animal transplantation experiments results indicated that PRDM9 significantly inhibited the osteogenesis of PDLSC in vivo, and the proportion of osteogenic area calculated showed that the osteogenic capacity of PRDM9sh [(3.8±2.41)%] was significantly lower than that in control group [(24.54±7.06)%](P<0.05). Conclusions: Depletion of PRDM9 repressed the osteogenic differentiation of stem cells from periodontal ligament in vitro and in vivo.

Abstract
BACKGROUND The optimal chemotherapeutics of recurrent disseminated glioblastoma has yet to be determined. We analyzed the efficacy and safety of recombinant human endostatin (rh-ES) combined with temozolomide and irinotecan in patients with recurrent disseminated glioblastoma. METHODS We retrospectively reviewed 30 adult patients with recurrent disseminated glioblastoma treated with this combination chemotherapy at Department of Neuro-Oncology, Sanbo Brain Hospital, Capital Medical University of China from November 2009 to August 2018. Temozolomide was given orally at 200 mg/m2 daily for 5 days and rh-ES was administrated 15 mg/d daily for 14 days of each 28-day treatment cycle. Irinotecan was given intravenously every 2 weeks on a 28-day cycle at 340 mg/m2 or 125 mg/m2 depending on antiepileptic drugs. Primary endpoint was progression-free survival (PFS) at 6 months (6 m-PFS). RESULTS The 6 m-PFS was 23.3%. The median PFS was 3.2 months. The overall survival rate (OS) at 12 months was 28.6%. The median OS was 6.9 months. Six out of 30 (20%) patients demonstrated partial radiographic response and 11 (36.7%) remained stable. The PFS of the 6 patients who got partial response was 5.8, 6.3, 6.9, 13.6, 15.8 and 16.6 months, respectively, and the median time interval of first response was 4 (range, 2.0-6.6) months. The most common adverse events were hematologic toxicities and gastrointestinal effects. The Grade ≥ 3 adverse event was hematologic toxicities. The adverse events were manageable. CONCLUSIONS Rh-ES, in combination with cytotoxic drugs, was an alternative effective regimen with manageable toxicities in treatment of recurrent disseminated glioblastoma.

BACKGROUND Spinosin, a major component of Samen Ziziphi spinosae, has been shown to modulate sedation and hypnosis; however, the underlying neuronal mechanisms of its stimulatory effects remain unclear. MATERIALS AND METHODS In the present study, we injected spinosin (15 mg/kg) or saline into mice, which were killed after 90 min. We isolated the brains, which were immunohistochemically stained for c-Fos as a biomarker for neuronal activation and assessed the expression profile of c-Fos in various sleep-arousal brain areas. RESULTS Our findings revealed that there were no statistically significant differences in the expression of c-Fos in the nucleus accumbens and ventrolateral preoptic area, the vertical limb of the diagonal band nucleus, horizontal limb of the diagonal band nucleus, ventral tuberomammillary nucleus, ventral tegmental area, and dorsal raphe nucleus relative to saline between saline and spinosin-treated mice. Unlike saline, spinosin markedly decreased c-Fos expression in the lateral hypothalamic area (LHA) as well as the locus coeruleus (LC). Compared to the saline injection, the application of spinosin also resulted in a marked decrease in c-Fos expression in the LHA orexin neurons. CONCLUSIONS These findings suggest that spinosin administration results in a restricted pattern of c-Fos expression within the LHA orexin neurons and the LC, suggesting that this particular neuronal inactivation contributes to sedation and hypnosis.

Abstract
OBJECTIVE
To analyze the response and toxicity of recombinant human endostatin (rh-ES) combined with carboplatin and vincristine (CV) chemotherapy regimen for pediatric low-grade gliomas (LGGs).
METHODS
Retrospectively reviewed the clinical data of the patients who were received rh-ES with CV chemotherapy regimen at Department of Neuro-Oncology, Sanbo Brain Hospital, Capital Medical University from October 2014 to October 2018. Carboplatin was administrated at a dose of 200~300 mg/m2 and the vincristine dose was 1.5 mg/m2 (maximum dose: 2 mg). Rh-ES was administrated 15 mg/d, daily for 14 days of each 28-day treatment cycle.
RESULTS
26 patients were enrolled. By the time of the last follow-up, 14 patients had completed the treatment and 6 were still in treatment. Of the 26 patients, 14 had partial response (PR), 12 had stable disease (SD), and the objective response rate (ORR) was 53.8%. Of the 14 patients who completed all the treatment, 10 achieved PR, 4 got SD, and the ORR was 71.4%. The median time interval to response was 3.3 months (range 2–12.6 months). The main adverse reactions were myelosuppression and allergy to carboplatin. Three patients were terminated in the consolidation phase due to adverse reactions.
CONCLUSIONS
The rh-ES combined with CV regimen is effective in the treatment of pediatric LGGs and had a rapid time interval to response, which is conducive to the rapid relief of brain stem or visual function damage.

Abstract
Gastric cancer is a common malignant tumor of digestive system. D2 procedure is recognized as the standard operation for advanced gastric cancer at present. However, controversies still exist in the standardization and quality control of surgical procedures. Total mesorectal excision (TME) and complete mesocolic excision (CME) based on the membrane anatomy perfectly solve these problems in the treatment for colorectal cancer. However, the complexity of mesogastrium determines that TME and CME cannot be easily transplanted to the treatment of gastric cancer. The practical membrane anatomy in gastric cancer surgery is just emerging and its impact on the treatment of gastric cancer is immeasurable. By reviewing the evolution and embryonic development of digestive system, and combining with actual operation, this paper analyzes and redefines several key issues such as traditional Toldt space, Gerota fascia and complete mesenteric excision. On this basis, we propose a novel and feasible surgical procedure named regional en bloc mesogastrium excision (rEME) for distal gastric cancer. The concept of en bloc mesogastrium excision (EME) based on membrane anatomy may have some influences on the lymph node grouping from the 'Japanese Classification of Gastric Carcinoma'. Performance of EME may reduce the controversies about the group of lymph nodes and their borders. EME in the infra-pyloric region weakens the significance of subdivision of No.6 lymph nodes into No.6a, No.6v and No.6i. More studies are needed in the construction of a mature theoretical system for practical membrane anatomy in gastric surgery.

Abstract
BACKGROUND Aplasia cutis congenita (ACC) in newborns is a condition in which congenital defects or hypoplasia is present in part of the epidermis, dermis and even subcutaneous tissue (including muscle and bones). First reported by Cordon in 1767, ACC is a rare disease with a low incidence of 1/100000 to 3/10000. Currently, there are 500 cases reported worldwide. ACC can be accompanied by other malformations. The onset mechanism of the disease remains unknown but is thought to be correlated to factors such as genetics, narrow uterus, foetal skin and amniotic membrane adhesion, use of teratogenic drugs in early pregnancy and viral infection.
CASE SUMMARY In August 2018, we treated a newborn with ACC on the left lower limbs using a combination of ionic silver dressing and moist exposed burn ointment (MEBO) and achieved a satisfactory treatment outcome. The skin defects were observed on the external genitals and on areas from the left foot to 3/4 of the upper left side. Subcutaneous tissue and blood vessels were observed in the regions with skin defects. The following treatments were provided. First, the wound was rinsed with 0.9% sodium chloride solution followed by disinfection with povidone-iodine twice. And then MEBO was applied to the wound at a thickness of approximately 1 mm. After applying ionic silver dressing, the wound was covered with sterile gauze. The wound dressing was replaced every 2-3 d. At the 4-mo follow-up, the treatment outcome was satisfactory. There was minimal scar tissue formation, and limb function was not impaired.
CONCLUSION The combination of ionic silver dressing and MEBO to ACC is helpful.

Abstract
Jatrorrhizine possesses a wide spectrum of pharmacological activities. However, the mechanism underlying hepatic uptake of jatrorrhizine remains unclear.Rat liver slices, isolated rat hepatocytes and human embryonic kidney 293 (HEK293) cells stably expressing human organic anion-transporting polypeptide (OATP) and organic cation transporter (OCT) were used to evaluate the hepatic uptake of jatrorrhizine in this study.Uptake of jatrorrhizine in rat liver slices and isolated rat hepatocytes was significantly inhibited by glycyrrhizic acid (Oatp1b2 inhibitor) and prazosin (Oct1 inhibitor), but not by ibuprofen (Oatp1a1 inhibitor) or digoxin (Oatp1a4 inhibitor). Uptake of jatrorrhizine in OATP1B3 and OCT1-HEK293 cells indicated a saturable process with the Km of 8.20 ± 1.28 and 4.94 ± 0.55 μM, respectively. However, the transcellular transport of jatrorrhizine in OATP1B1-HEK293 cells was not observed. Rifampicin (OATP inhibitor) for OATP1B3-HEK293 cells and prazosin for OCT1-HEK293 cells could inhibit the uptake of jatrorrhizine with the IC50 of 5.49 ± 1.05 and 2.77 ± 0.72 μM, respectively.The above data indicate that hepatic uptake of jatrorrhizine is involved in both OATP and OCT, which may have important roles in jatrorrhizine liver disposition and potential drug-drug interactions.

Abstract
Backgrounds: (6aS, 10S, 11aR, 11bR, 11cS)-10-methylaminododecahydro-3a, 7a-diaza-benzo (de) anthracene-8-thione (MASM), a novel derivative of matrine, exhibits better anti-inflammatory activity. This study was designed to evaluate the protective effect of MASM on acute and chronic liver injuries and explore the possible mechanisms. Methods: Acute and chronic liver injury models were established by the CCl4 intraperitoneal injection and the protective effect of MASM was assessed by biochemical and histological examination. The infiltration of different monocyte subsets into the liver was characterized and analyzed by flow cytometry. The in vitro effect of MASM on liver nonparenchymal cells was evaluated by real-time PCR and transwell chemotaxis assays. Results: Administration of MASM markedly attenuated acute liver injury and liver fibrosis induced by CCl4 injection. Meanwhile, the infiltrations of Gr1hi monocytes in injured livers and induced hepatic expression of monocyte chemoattractant protein-1 (MCP-1) were greatly inhibited. Cellular experiments demonstrated that MASM not only decreased the expression of MCP-1 but also inhibited its chemotactic activity. Conclusions: This study demonstrates that the protective effect of MASM on liver injury could be contributed to the suppression of Gr1hi monocyte infiltration to the liver and the inhibition of MCP-1 production and activity. These findings provide new insights into the protective role of MASM in liver injury.

Abstract
The Ca2+ induced Spontaneous Oscillatory Contraction (Ca-SPOC) of cardiac myofibrils oscillate with a period similar to resting heartbeat of several animal species, and its auto-oscillatory properties set the basic rhythm of cardiac contraction. To explain the dynamics of Ca-SPOC, the present paper constructs a novel chemical kinetical model based upon the cooperative behavior between the two heads of myosin II dimer, also considering the reaction-diffusion effect of ATP inside myocardial fibers. The simulation results show that the concentration of ATP inside myocardial fibers oscillates over time under some special conditions, together with the proportions of myosin II dimers in different states periodically changing with time, which contributes to produce the sustained oscillations of contractive tension. These results indicate that the SPOC of muscles may be partly due to chemical oscillation involved in the actomyosin ATPase cycle, which has been ignored by the previous theoretical studies.

Abstract
Myosin V is a processive doubled-headed biomolecular motor involved in many intracellular organelle and vesicle transport. The unidirectional movement is coupled with the adenosine triphosphate (ATP) hydrolysis and product release cycle. With the progress of experimental techniques and the enhancement of measuring directness, detailed knowledge of the motility of myosin V has been obtained. Following the ATPase cycle, the 4-state mechanochemical model of the myosin V's processive movement is used. The transitions between various states take place in a stochastic manner. We can use the master equation to analyze and calculate quantitatively. Meanwhile, the effect of the reverse reaction is taken fully into account. We fit the mean velocity, the mean dwell time, the mean run length, and the ratio of forward/backward steps as a functionof ATP, ADP, and Pi concertration. The theoretical curves are generally in line with the experimental data. This work provides a new insight for the characteristic of myosin V.
