ABSTRACT

Objective Bamboo node (BN) of vocal folds is a rare disease which is mostly associated with autoimmune diseases and always involves women as reported in literature. The purpose of this study is to investigate the clinical characteristics and the treatments in a series of BN cases. Methods We retrospectively collected and reviewed clinical information of all patients who presented bamboo nodes by fibreoptic laryngoscopy from 2011 to 2020 in our hospital, including the demographic information, clinical symptoms, associated autoimmune diseases, voice abuse, treatments, and outcomes. Patients were followed up periodically at clinics with fibreoptic laryngoscopy and/or voice recovery evaluation using the self-assessed voice visual analog scale (VAS). Results Totally 14 patients were diagnosed with BN and were included in the study. BN involved both women (8/14, 57.1%) and men (6/14, 42.9%). Bilateral lesions were found in 13 patients (92.9%). The most common symptom of BN was hoarseness (100%). Ten (71.4%) of 14 patients experienced voice abuse. Thirteen (92.9%) of them were concomitant with autoimmunity disease, and received medication therapy for the underlying autoimmune diseases; one patient received anti-acid treatment for the gastroesophageal reflux disease. Voice rests were performed in all patients. Voice recovered completely in 3 cases (21.4%), improved remarkably in 8 cases (57.1%), improved slightly in 1 case (7.1%), and no improvement in 2 cases (14.3%). Conclusions BNs are mostly associated with autoimmune disease and vocal abuse. It may occur in both females and males. Conservative treatment for the underlying autoimmune diseases and vocal rest are beneficial to voice recovery in most of the patients, and can be used as the first choice of treatment.

ABSTRACT

To systemically evaluate the efficacy and safety of Gingko Ketone Ester Dropping Pills in treating angina pectoris and co-ronary heart disease. CNKI, Wanfang, SinoMed, PubMed, Cochrane Library and EMbase databases were retrieved on computer, and the randomized clinical trial(RCT) on Gingko Ketone Ester Dropping Pills in treating angina pectoris and coronary heart disease, which were published from the database establishment to December 31, 2019, were comprehensively collected. Literature screening, data extraction and quality evaluation were conducted independently by two researchers according to inclusion and exclusion criteria. Literature methodology quality evaluation was conducted with use of the Cochrane Handbook 5.3.0(bias risk assessment tool). Meta-analysis was performed with RevMan 5.3.0 software. A total of 10 RCTs were included. The results of the Meta-analysis showed that as compared with conventional Western medicine alone, the application of Gingko Ketone Ester Dropping Pills combined with conventional Western medicine treatment further improved the total effective rate and electrocardiogram effect(RR=1.43,95%CI[1.20,1.71],P<0.000 1). There were statistically significant differences in the number of angina attacks, the duration of angina and the amount of nitroglycerin used. In terms of safety indicators, four studies reported adverse reactions in the experimental group, including facial flu-shing, tachycardia, dizziness, dyspnea, nausea and other symptoms. Based on the existing findings, in the treatment of angina pectoris and coronary heart disease, Gingko Ketone Ester Dropping Pills combined with conventional Western medicine can improve the clinical total effective rate, electrocardiogram effect, number of angina attacks, duration of angina and the amount of nitroglycerin used. However, in the included studies, due to some methodological quality problems which would impact the reliability of literature results more high-quality randomized controlled trials are still needed for further verification.

ABSTRACT

With the increasing incidence of hepatobiliary diseases, it is particularly important to understand the role of molecular, cellular and physiological factors in the clinical diagnosis and treatment with traditional Chinese medicine(TCM) in the development of liver disease. Appropriate animal models can help us identify the possible mechanisms of relevant diseases. Danio rerio(zebrafish) model was traditionally used to study embryonic development, and has been gradually used in screening and evaluation of liver diseases and relevant drug in recent years. Zebrafish embryos develop rapidly and the digestive organs of 5-day-old juvenile fish are all mature. At this stage, they may develop hepatobiliary diseases induced by developmental defects or compounds. Zebrafish liver is similar to human liver in cell composition, function, signal transduction, response to injury and cell process mediating liver disease. Furthermore, due to the high conservation of genes and proteins between humans and zebrafish, zebrafish becomes an alternative system for studying basic mechanisms of liver disease. Therefore, genetic screening could be performed to identify new genes involving specific disease processes, and chemical screening could be made for drugs in specific processes. This paper briefly introduced the experimental properties of zebrafish as model system, emphasized the study progress of zebrafish models for pathological mechanism of liver diseases, especially fatty liver, and drug screening and evaluation, so as to provide ideas and techniques for the future liver toxicity assessment of TCM.

ABSTRACT

To evaluate the efficacy and safety of Compound Danshen Injection combined with Western medicine in the treatment of vascular dementia. Databases of Cochrane Library, PubMed, EMbase, CNKI, SinoMed, VIP, Wanfang Data were electronically retrieved for collecting randomized controlled trial(RCT)about vascular dementia treated with Western medicine alone or combined with Compound Danshen Injection from the year of database establishment to January 2020. Two researchers independently screened out li-teratures, extracted data, and evaluated the risk of bias for inclusion in the study. Meta-analysis was conducted using RevMan 5.3 software. A total of 5 RCTs were included, involving 588 patients, with 299 in treatment group and 289 in control group. Meta-analysis results showed that compared with Western medicine alone, Compound Danshen Injection combined with Western medicine was better in the effective rate(RR=1.23,95%CI[1.14,1.33],P<0.000 01), MMSE score(MD=3.54,95%CI[3.01,4.06],P<0.000 01), ADL score(MD=11.49,95%CI[8.05,14.93],P<0.000 01), the level of CRP(MD=-0.72,95%CI[-1.25,-0.20],P=0.007) and the level of IL-6(MD=-7.64,95%CI[-9.65,-5.63],P<0.000 01). Adverse reactions mainly included rash and skin prick, which did not affect the treatment effect. Based on the findings, the combination of Compound Danshen Injection in the treatment of vascular dementia could improve the effective rates, relieve the mental state damage and improve the daily living ability, with mild adverse reactions and a low incidence. However, due to the low quality of the included literatures, high-quality and large-scale randomized controlled trials are needed for further verification.

ABSTRACT

This study aimed to comprehensively analyze and compare the differences of different clinical study types currently published in the safety evaluation of Xuebijing Injection. Six databases, namely the Cochrane Library, PubMed, EMbase, CNKI, VIP and Wanfang database, were electronically retrieved to collect all types of studies on the safety of Xuebijing Injection, including randomized controlled trials, case-controlled studies, cohort studies, systematic reviews, and centralized monitoring studies of clinical safety(hospital), in order to comprehensively and objectively evaluate the safety of Xuebijing Injection, and analyze the differences of different research results. A total of 211 literatures were included, involving a total of 46 384 patients treated with Xuebijing Injection, and 423 adverse reactions(ADRs) occurred. They included 191 randomized controlled trials, 3 cohort studies, 15 systematic reviews, and 2 centralized monitoring studies of clinical safety(hospital), and the incidence of adverse reactions was 2.54%(common), 2.31%(common), 0.95%(occasionally), and 0.50%(occasionally). More than half of the 423 cases of ADRs occurred in skin and adnexal system(151 cases) and gastrointestinal system(65 cases), including such manifestations as rash, skin itching, nausea and vomiting, diarrhea. The degree of ADRs was mild. Randomized controlled trials showed that the incidence of ADR was the highest when Xuebijing Injection was used for malignant tumor and multiple organ failure. And the systematic evaluation showed that the incidence of ADR was the highest when Xuebijing Injection was used for spontaneous peritonitis of liver cirrhosis. In conclusion, different study types could lead to significant differences in the results of drug safety evaluation. Sample size, study type, and quality control are the main factors for biased results. Due to large sample size and high-quality, centralized monitoring studies become the better clinical safety evaluation model of drugs at present, and full life cycle management could more objectively reflect drug safety and guide clinical rational drug use.

ABSTRACT

Gestational diabetes mellitus(GDM)can cause blood glucose disorders in pregnant women and result in adverse maternal-neonatal outcomes.Vitamin D(VD)can improve glucose tolerance and insulin sensitivity,and thus theoretically,VD supplementation during pregnancy could improve glycemic control as well as maternal-neonatal outcomes in GDM patients.Although studies have shown that VD deficiency is associated with poor maternal-neonatal outcomes in GDM patients,no solid conclusion has been drawn with regard to the effects of VD supplementation on these patients.Therefore,here we summarized the research progress of the effects of VD supplementation on glycemic control and adverse maternal-neonatal outcomes in GDM patients,in an effort to guide the clinical VD supplementation during pregnancy.

ABSTRACT

Objective:To screen the common low-frequency mutation sites in primary biliary cholangitis (PBC) by whole exome sequencing (WES), in order to find PBC-related new susceptibility genes.Methods:From January 2000 to December 2017, the clinical data of seven patients with PBC of three PBC families diagnosed at General Hospital of Tianjin Medical University and two healthy controls were collected. The DNA blood samples were extracted and analyzed by WES. SAMtools 1.3 software was used to detect gene single nucleotide polymorphism (SNP) and indel sites, and gene mutation sites were screened from known databases of 1000 Genome, ExAC, ESP6500 and Novo-Zhonghua gene database. Pymol V2.3.2 software was performed to simulate the three-dimensional structure of major histocompatibility complex-Ⅱ (MHC-Ⅱ), and the amino acid position corresponding to the common mutation sites among families were observed.Results:The age of first diagnosis of seven PBC patients was (61.2±10.2) years. The results of serum test of seven patients indicated that alkaline phosphatase (ALP) level was (306.9±242.5) U/L, γ-glutamyltranspeptidase (GGT) level was (121.7±85.9) U/L, alanine aminotransferase (ALT) level was (47.6±33.1) U/L, aspartate aminotransferase (AST) level was (55.7±34.1) U/L and immunoglobulin G level was (14.9±3.1) g/L. The antinuclear antibody were all cytoplasmic granule types and anti-mitochondrial antibody were all positive. Five PBC patients developed intra-abdominal lymphadenopathy; two patients had extrahepatic autoimmune diseases and the pathological results of liver biopsy of two patients both showed interface hepatitis and small bile duct lesions. Eighteen SNPs were common in three PBC families, which were located in the gene of OTOA, OBSCN and human leucocyte antigen- DRB1( HLA- DRB1). rs200988634 located in OTOA gene was a common polymorphic locus among the three families. rs746424683, rs545316651, rs553144914, rs533059830 and rs56087721 located in OBSCN caused the changes of nine amino acids of different location. There were 12 SNP variations located in HLA- DRB1 gene, which leaded to the changes of 12 amino acids of different location, among them rs16822698, rs112796209 and rs11554463 mutation induced G154A, Y152C and Y107X amino acid variation of MHC-Ⅱ beta chain, and Y107X amino acid was located in the groove region of MHC-Ⅱ binding with peptide. Conclusions:WES in PBC families is a good strategy to elucidate the candidate deleterious mutation genes OBSCN and OTOA. HLA- DRB1 which is a susceptible gene of PBC may affect MHC-Ⅱ mediated antigen presentation process by the changing amino acid sequence.

ABSTRACT

Objective:To evaluate the application value of small IT knife pre-cut in assistance to duodenal papillary cannulation compared with conventional guidewire cannulation.Methods:A retrospective analysis was performed on the data of 90 patients with choledocholithiasis including 52 patients with small IT knife pre-cut assisted intubation (small IT knife group) and 38 patients with conventional guidewire intubation (conventional group) in endoscopic retrograde cholangiopancreatography (ERCP) from May 2016 to July 2019 in the digestive endoscopy center of Nanjing Drum Tower Hospital. The basic data, curative effect and complications of the two groups were collected and compared.Results:There was statistically significant difference in gender composition between the small IT knife group and the conventional group ( χ2=5.679, P=0.017), but no significant difference in other baseline data between the two groups (all P>0.05). The median intubation time of the small IT knife group was significantly shorter than that of the conventional group (141.5 s VS 270.0 s, Z=1 268.0, P=0.022). There were no significant differences in the success rate of intubation [98.1% (51/52) VS 94.7% (36/38), χ2=0.760, P=0.571], the incidence of intraoperative bleeding [15.4% (8/52) VS 7.9% (3/38), χ2=1.148, P=0.345], postoperative pancreatitis [5.8% (3/52) VS 7.9% (3/38), χ2=0.159, P=0.694], and postoperative cholangitis [1.9% (1/52) VS 5.3% (2/38), χ2=0.760, P=0.571] between the two groups. No perforation occurred in the two groups. After stratifying according to the operator′s proficiency, the median intubation time was significantly different between the small IT knife expert group and the conventional expert group (116.0 s VS 258.0 s, Z=276.0, P=0.038), while there was no significant difference in the intubation time among other groups (all P>0.05). Conclusion:The small IT knife is safe and effective to pre-cut and assist intubation in ERCP, and it may shorten the intubation time.

ABSTRACT

Objective:To investigate the clinical characteristics of neonatal congenital tongue base cyst.Methods:This retrospective study involved 35 neonates with congenital tongue base cyst diagnosed in the neonatal intensive care unit (NICU) of Xi'an Children's Hospital from June 2013 to December 2019. General information, clinical manifestations, supplementary results, treatment and prognosis of these babies were described.Results:(1) The median age at the onset of the disease was 12.5 (0~28) d and the median age at admission was 15 (0~28) d for these babies. The main clinical manifestations were laryngeal stridor (28/35, 80.0%), inspiratory dyspnea and crying, especially when feeding (26/35, 74.3%) and choking and spitting with feeding (23/35, 65.7%). (2) Among the 35 cases, 15 (42.9%) required emergency endotracheal intubation due to significant dyspnea when were admitted to the NICU and five out of them were considered for having tongue base mass under laryngoscopy, while the other 10 cases underwent bedside electronic laryngoscopy after endotracheal intubation, in which space-occupying lesions were found. Tongue base cyst was considered in seven cases with laryngeal stridor complicated by protracted pneumonia using fiberoptic bronchoscopy. The other 13 cases were examined by electronic laryngoscope and considered as tongue base cyst. Thirty-five cases underwent cervical ultrasound and only five of them were considered as tongue base tumor. Thirty-two cases underwent cervical CT scan and only two of them were normal. Three cases were found to have tongue base cyst by cranial MRI. (3) Thirty-four cases were treated by radiofrequency ablation assisted with self-retaining microlaryngoscope and general anesthesia, while the other one firstly received puncture and drainage under direct laryngoscope due to the difficult intubation because of the huge tongue base cyst and then underwent surgery when stable. Only one case (2.9%) relapsed after surgical treatment during regular follow-up.Conclusions:Neonatal congenital tongue base cyst has an early onset and atypical clinical manifestations. Electronic laryngoscopy/fiberoptic bronchoscopy combined with neck CT or MRI examination should be performed promptly in patients with laryngeal stridor and inspiratory dyspnea to facilitate the accurate diagnosis and timely surgery is required for.

ABSTRACT

Objective:To investigate the safety and prognostic value of neoadjuvant chemotherapy and surgery for advanced gastric cancer patients with para-aortic lymph node metastasis.Methods:Clinicopathological data of 25 patients admitted to the Department of Gastrointestinal Surgery, Fujian Cancer Hospital from Jan 2015 to Jun 2017 were retrospectively analyzed. All patients were treated with SOX chemotherapy for 3 cycles. D 2 + paraaortic lymphadenectomy was performed in patients with stable disease (SD) . After operation, SOX regimen was used for 5 cycles of chemotherapy. Results:After 3 cycles of neoadjuvant chemotherapy, there were 2 cases with progressive disease, 6 cases of SD and 17 cases of partial remission. There was no treatment-related death. Twenty-three patients underwent surgery, including 19(76%) patients of R 0 resection. Tirty-four out of 128 para aortic lymph nodes were metastatic. Postoperative complications occurred in 5(22%) patients, with no mortality . The median progression free survival time and median overall survival time were 20 and 29 months respectively. The 1, 3-year overall survival rates were 80% and 48%, and the 1-year and 3-year progression free survival rates were 72% and 38%, respectively. For those with para-aortic lymph node metastasis the 1-year and 3-year OS rate were 70% and 17%, respectively. Multivariate analysis showed that the efficacy of neoadjuvant chemotherapy was an independent prognostic factor. Conclusion:Neoadjuvant chemotherapy is among others an independent prognostic factor affecting the post-op survival of advanced gastric carcinoma with para-aortic lymph node metastasis.

ABSTRACT

Objective:To discuss the feasibility and clinical efficacy of laparoscopic ureteroplasty with buccal mucosa graft for ureteral stricture.Methods:The clinical data of 10 patients with ureteral stricture admitted to the Second Affiliated Hospital of Anhui Medical University from July 2018 to November 2019 were retrospectively analyzed, including 7 males, 3 females, 5 cases on each side, with an average age of (47.9±7.8)years. All patients had a history of operation related to ureteral calculi. The median value of preoperative serum creatinine was 71(68~610)μmol/L. The status of hydronephrosis and ureteral stricture was evaluated by ultrasonography, CTU and ureteral retrograde angiography.The separation of the renal pelvis on the affected side was (3.1±0.7)cm.There were 7 cases of upper segment stenosis, 2 cases of middle segment stenosis, and 1 case of multiple stenosis. The length of ureteral stenosis was (3.2±0.7)cm. Laparoscopic buccal mucosa ureteroplasty was performed in all 10 cases under general anesthesia. After the stricture ureter segment was separated during the operation, the ureteral stenosis segment was longitudinally cut. According to the stenosis, the buccal mucosa with a length of 3.0-4.5 cm and a width of 1.0-1.5 cm was cut. Buccal mucosa grafts were harvested and placed in the ureter as an anterior onlay with omental wrapping.Results:Ureteral repair was performed laparoscopically in all cases, with no conversion to open and no serious complications. The operative time was (199.2±27.4)min, the blood loss was (101.5±54.7)ml, the median postoperative indwelling time of the drainage tube was 4.5(3.0-7.0)d, and the postoperative hospital stay was (7.9±1.9)days. The patients had clear pronunciation and barrier-free eating one week after the operation.The double J tube was removed one to two months after surgery. The patients were followed up for (11.3±4.2)months after the operation. Follow-up patients underwent imaging and other examinations, which showed significant improvement in hydronephrosis on the affected side, and the median value of renal pelvis separation on the affected side was 1.8(0-2.2)cm. The median value of serum creatinine was 82(66~235)μmol/L. The serum creatinine in 2 patients with renal insufficiency decreased significantly after operation.Conclusions:Laparoscopic buccal mucosa graft ureteroplasty could be a safe and feasible option for the treatment of ureteral stricture with less trauma and rapid recovery. The results of the initial experience are encouraging.

ABSTRACT

Objective:To explore the damage of the intestinal mucosal barrier of septic rats by the activation of NOD-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasomes and the role of Ulinastatin (UTI) on the expression of intestinal nuclear factor-κB (NF-κB)/NLRP3 inflammasome signaling pathway in septic rats.Methods:According to the random number table method, 64 male Wistar rats were divided into sham operation group (Sham group), cecal ligation and puncture (CLP) group, UTI treatment group (100 kU/kg UTI was intraperitoneally injected 1, 6, 12 and 18 hours after CLP), and UTI pretreatment group (100 kU/kg UTI was given 1 hour before CLP), with 16 rats in each group. The survival of rats was observed after 24 hours, and the blood was collected from abdominal aorta at 24 hours after modeling, then rats were killed and their ileum tissues were taken. Hematoxylin-eosin (HE) staining was used to observe histopathological changes and Chiu score. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and intestinal fatty acid binding protein (I-FABP) in serum were detected by enzyme linked immunosorbent assay (ELISA). The protein expression of NF-κB p65 in intestinal tissue was detected by Western blotting. The expression of intestinal tight junction proteins Claudin-1, Occludin and the inflammasome NLRP3, apoptosis-associated speck-like protein containing CARD (ASC) and caspase-1 were detected by immunohistochemistry.Results:Compared with Sham group, the 24-hour survival rate of CLP group was significantly reduced. Histopathological results showed that the CLP group had severe edema of mucosa and submucosal stroma with obvious infiltration of inflammatory cells and disordered villi arrangement. Some glands were incomplete, and the villus structure was severely damaged. The Chiu score was significantly increased. The levels of TNF-α, IL-1β, I-FABP in serum and the protein expression of NF-κB p65 in intestinal tissue were significantly increased. The positive expressions of NLRP3, caspase-1 and ASC were also significantly increased. However, the positive expression of tight junction protein in small intestine tissue such as Occludin and Claudin-1 were significantly reduced. It suggested that when sepsis occurs, small intestinal mucosal barrier dysfunction happens, and mucosal permeability increases, while tight junction protein expression decreases, NLRP3 inflammasome and its upstream molecule NF-κB p65 were activated. After UTI treatment and UTI pretreatment intervention, although there was no significant difference in 24-hour survival compared with CLP group (62.5%, 68.8% vs. 43.8%, both P > 0.05), the intestinal tissue damage of septic rats was significantly improved. Specifically: Chiu score and the levels of TNF-α, IL-1β, I-FABP in serum were significantly decreased [Chiu score: 3.37±0.25, 3.23±0.16 vs. 4.08±0.13, TNF-α (ng/L): 147.62±20.74, 140.71±24.81 vs. 222.82±16.84, IL-1β (ng/L): 80.64±5.68, 78.11±4.75 vs. 133.73±3.92, I-FABP (μg/L): 38.29±3.60, 35.88±4.52 vs. 59.81±4.66, all P < 0.05]; the protein expression of NF-κB p65 was significantly decreased (NF-κB p65/β-actin: 0.65±0.10, 0.69±0.11 vs. 0.99±0.10, both P < 0.05), the positive expressions of Claudin-1 and Occludin in the small intestine tissue were increased [Claudin-1 positive expression area: (19.43±3.08)%, (23.99±6.27)% vs. (7.77±2.03)%; Occludin positive expression area: (19.58±4.75)%, (23.28±3.68)% vs. (11.69±4.30)%, all P < 0.05], while the positive expressions of NLRP3, caspase-1, ASC were decreased [NLRP3 positive expression area: (7.80±3.14)%, (6.86±2.63)% vs. (14.44±3.68)%; caspase-1 positive expression area: (10.62±3.52)%, (9.49±3.09)% vs. (26.69±8.05)%; ASC positive expression area: (9.95±2.81)%, (10.53±3.61)% vs. (24.16±5.48)%, all P < 0.05]. However, there was no significant difference in the improvement effect between UTI treatment group and UTI pretreatment group.Conclusions:Intestinal barrier dysfunction in sepsis may be related to the activation of NLRP3 inflammasomes in the intestinal mucosa. The protective effect of UTI in the intestinal mucosa may be related to inhibiting the activation of NLRP3 inflammasomes in the intestinal mucosa, but UTI pretreatment has no obvious advantage compared with UTI treatment.

ABSTRACT

Objective:To find out predictors of the testicular ischemia caused by incarcerated inguinal hernia and evaluate the ischemic injury of the testis more accurately, which can indicate testicle exploration in time or prevent unnecessary testicle exploration.Methods:Pediatric patients (median: 9 months) undergoing operation of unilateral incarcerated inguinal hernia and ipsilateral testicular exploration from 1 Jul. 2013 to 30 Jun. 2019 were retrospectively investigated. Age at surgery, incarcerate duration, degree of intestinal and testicular injury, times of manual reduction and preoperative ultrasound data were collected. Statistical analysis was performed by SAS 9.4 (Copyright ? 2016 SAS Institute Inc.Cary, NC, USA) .Results:460 patients (median: 9 months) , of which 57 (12.39%) (median: 1.4 months, interquartile range 0.8-10.7 months) had severe testicular injury, and their average incarceration time was (23.9±9.3) h. Univariate logistic regression revealed that increased times of manual reduction, ultrasound scores, incarcerate duration and degree of intestinal injury were positively correlated with the degree of testicular ischemia, while age at surgery was negatively correlated with the degree of testicular ischemia ( P<0.05) . A model for calculating the probability of severe testicular ischemia injury was established: P= through multivariate analysis with backward stepwise logistic regression and 10-fold cross-validation was used for preliminary verification of the model. Conclusion:This study provides a relative reliable model to predict the risk of irreversible testicular ischemia due to incarcerated inguinal hernia using readily available clinical characteristics in young pediatrics with testicular ischemia.

ABSTRACT

Objective:To compare the clinical efficacy of the Simultaneous three scopes combined surgery [laparoscopic cholecystectomy(LC)+ choledochoscopy exploration + choledochectomy and removal of the common bile duct + primary suture of the common bile duct + endoscopic guided nasobiliary duct placement] and staged two scopes surgery[endoscopic retrograde cholangiopancreatography (ERCP) combined with LC] in the treatment of choledocholithiasis and cholecystolithiasis.Methods:From January 2018 to June 2020, we retrospectively analyzed the clinical data of 83 patients with choledocholithiasis and choledocholithiasis, who underwent minimally invasive treatment in our center. According to the different surgical procedures, the patients were divided into three-mirror group ( n=42) and two-mirror group ( n=41). All patients in the three-mirror group underwent three-scopy combined surgery. The patients in two-mirror group received endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC). In this study we compared the relevant clinical indicators of the two groups, in terms of the operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, postoperative defecation time, total hospitalization cost, incidence of postoperative acute pancreatitis, postoperative stone recurrence rate, incidence of postoperative cholangitis, and incidence of postoperative biliary fistula, total hospitalization time, postoperative bile duct stricture rate. Use SPSS 26.0 software to statistically analyze various indexes such as intraoperative, postoperative, follow-up, etc. Normally distributed measurement data were described by the mean±standard deviation ( Mean± SD), the comparison between groups was by t test, and measurement data with skewed distribution were destribed as M( P25, P75), Pairwise comparisons were analyzed using nonparametric test. The comparison of count data between groups was by the chi-square test. Results:No death was observed in both two groups. The operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, and postoperative defecation time of the three-mirror groupwere (167.98±47.37) min, 50(50, 100) mL, 100%(42/42), (2.10±0.76) days, 3(3, 4) days, the two-mirror group were (143.80±34.47) min, 50(50, 50) mL, 85.4%(35/41), (1.53±0.99) days and 2(1, 3) days. Compared with the two groups, the three-mirror group was higher than the two-mirror group, and the difference was statistically significant ( P<0.05).

ABSTRACT

Jie-Geng-Tang (JGT), a traditional formula, is employed in the treatment of sore throat and cough and comprises Platycodonis Radix and Glycyrrhizae Radix et Rhizoma in the ratio 1 : 2. Our previous study demonstrated that JGT protected mice from S. aureus-induced acute lung injury (ALI). Five constituents of JGT showed antibacterial activities against S. aureus in vitro. However, the potential effective constituents of JGT in vivo were still unclear. In this study, the chemical constituents of JGT were identified by liquid chromatography with quadrupole time-of-flight spectrometry (LC-Q-TOF-MS). A total of 96 constituents were identified or assumed, including seven organic acids, 45 flavonoids, 36 triterpene saponins, and eight compounds of other types. The structures of 31 of the constituents were confirmed by comparing them with corresponding authentic standards. Moreover, 15 prototypes and 49 metabolites were deduced in the serums of mice, 24 prototypes and 47 metabolites were deduced in the lungs of mice after the oral administration of JGT. Three types of constituents, namely organic acids, flavonoids, and triterpene saponins, could be absorbed into the blood. Moreover, flavonoids and triterpene saponins were more likely distributed in the lung than in the blood. To the best of our knowledge, this is the first report on the systematic metabolites profile of JGT in vivo. The results reported were beneficial to the elucidation of the effective material basis of JGT.

ABSTRACT

Traditional Chinese medicine (TCM) is a precious treasure of the Chinese nation and has unique advantages in the prevention and treatment of diseases. The holistic view of TCM coincides with the new generation of medical research paradigm characterized by network and system. TCM gave birth to a new method featuring holistic and systematic "network target", a core theory and method of network pharmacology. TCM is also an important research object of network pharmacology. TCM network pharmacology, which aims to understand the network-based biological basis of complex diseases, TCM syndromes and herb treatments, plays a critical role in the origin and development process of network pharmacology. This review introduces new progresses of TCM network pharmacology in recent years, including predicting herb targets, understanding biological foundation of diseases and syndromes, network regulation mechanisms of herbal formulae, and identifying disease and syndrome biomarkers based on biological network. These studies show a trend of combining computational, experimental and clinical approaches, which is a promising direction of TCM network pharmacology research in the future. Considering that TCM network pharmacology is still a young research field, it is necessary to further standardize the research process and evaluation indicators to promote its healthy development.

ABSTRACT

TANK-binding kinase 1 (TBK1), a core kinase of antiviral pathways, activates the production of interferons (IFNs). It has been reported that deacetylation activates TBK1; however, the precise mechanism still remains to be uncovered. We show here that during the early stage of viral infection, the acetylation of TBK1 was increased, and the acetylation of TBK1 at Lys241 enhanced the recruitment of IRF3 to TBK1. HDAC3 directly deacetylated TBK1 at Lys241 and Lys692, which resulted in the activation of TBK1. Deacetylation at Lys241 and Lys692 was critical for the kinase activity and dimerization of TBK1 respectively. Using knockout cell lines and transgenic mice, we confirmed that a HDAC3 null mutant exhibited enhanced susceptibility to viral challenge via impaired production of type I IFNs. Furthermore, activated TBK1 phosphorylated HDAC3, which promoted the deacetylation activity of HDAC3 and formed a feedback loop. In this study, we illustrated the roles the acetylated and deacetylated forms of TBK1 play in antiviral innate responses and clarified the post-translational modulations involved in the interaction between TBK1 and HDAC3.

ABSTRACT

Exosomes are nanometer-sized vesicles that contain various types of biologically active components, including proteins, nucleic acids, carbohydrates, and lipids, which vary with the type and physiological state of the cell. In recent years, several studies have showed that exosomes can provide new non-invasive diagnostic and prognostic biomarkers in patients affected by cancers, including bladder cancer (BC), and the lipid bilayer membrane structure makes exosomes as promising delivery vehicles for therapeutic applications. Exosomes have the characteristics of high abundance, high stability, tissue specificity, and wide distribution in body fluids, and are secreted as various types by cells in different states, thereby possessing great potential as biomarkers for BC. Herein, we briefly summarize the functions and roles of exosomes in the occurrence and development of BC and the current progress of research on exosomes in BC, while focusing on potential clinical applications of the diagnosis, treatment, and prognosis of BC.

ABSTRACT

OBJECTIVE@#To investigate the clinical correlation of expression level changes of miR-181b and miR-194 to the pathogenesis of acute graft-versus-host disease (aGVHD), and determine plasma miR-181b and miR-194 as the potential biomarkers for aGVHD.@*METHODS@#The plasma samples were collected from 31 patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at before HSCT, 15 days after HSCT and onset of aGVHD. The expression levels of miR-181b and miR-194 were detected by quantitative real-time PCR. Receiver-operating characteristic (ROC) curves and the area under the ROC curve (AUC) were used to assess the sensitivity and specificity of miRNA biomarkers for the diagnosis of aGVHD.@*RESULTS@#MiR-181b and miR-194 downregulated after treatment were significantly upregulated in the plasma at onset of aGVHD (P0.05). The expressions of plasma miR-181b and miR-194 collected on day 15 after HSCT were significantly upregulated in the patients with aGVHD in comparison with non-GVHD patients (P<0.05). Moreover, these elevated miRNAs were detected before aGVHD. The AUC of miR-181b predicting aGVHD was 0.91±0.05 (specificity was 0.94, sensitivity was 0.69). The AUC of miR-194 predicting aGVHD was 0.91±0.06 (specificity was 0.94, sensitivity was 0.77).@*CONCLUSION@#MiR-181b and miR-194 may serve as early biomarkers for the diagnosis and prognosis of aGVHD.
