RESUMEN

BACKGROUND: Partial splenic embolization (PSE) has been suggested as an alternative to splenectomy in the treatment of hypersplenism. However, some patients may experience recurrence of hypersplenism after PSE and require splenectomy. Currently, there is a lack of evidence-based medical support regarding whether preoperative PSE followed by splenectomy can reduce the incidence of complications. AIM: To investigate the safety and therapeutic efficacy of preoperative PSE followed by splenectomy in patients with cirrhosis and hypersplenism. METHODS: Between January 2010 and December 2021, 321 consecutive patients with cirrhosis and hypersplenism underwent splenectomy at our department. Based on whether PSE was performed prior to splenectomy, the patients were divided into two groups: PSE group (n = 40) and non-PSE group (n = 281). Patient characteristics, postoperative complications, and follow-up data were compared between groups. Propensity score matching (PSM) was conducted, and univariable and multivariable analyses were used to establish a nomogram predictive model for intraoperative bleeding (IB). The receiver operating characteristic curve, Hosmer-Lemeshow goodness-of-fit test, and decision curve analysis (DCA) were employed to evaluate the differentiation, calibration, and clinical performance of the model. RESULTS: After PSM, the non-PSE group showed significant reductions in hospital stay, intraoperative blood loss, and operation time (all P = 0.00). Multivariate analysis revealed that spleen length, portal vein diameter, splenic vein diameter, and history of PSE were independent predictive factors for IB. A nomogram predictive model of IB was constructed, and DCA demonstrated the clinical utility of this model. Both groups exhibited similar results in terms of overall survival during the follow-up period. CONCLUSION: Preoperative PSE followed by splenectomy may increase the incidence of IB and a nomogram-based prediction model can predict the occurrence of IB.

RESUMEN

OBJECTIVE: Early nutritional support in patients with gastric cancer can improve their nutritional status, but the impact on immune function has not been confirmed. This study aimed to analyze the effects of Qihuang decoction combined with enteral nutrition on nutrition and the immune function of postoperative gastric cancer. METHODS: 120 patients with postoperative gastric cancer in the study group and 117 in the control group were selected as the study subjects from our hospital at random. Indications of nutrition and immune and the rates of complications were compared the day before surgery and 1, 3, 7, and 14 days after surgery. RESULTS: Indications of nutrition except hemoglobin (HB) in the study group were significantly higher than those before operation and the albumin (ALB) and prealbumin (TP) were significantly increased 7 and 14 days after surgery (P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 versus P < 0.001 and P < 0.001) and the protein (PA) 3, 7, and 14 days after surgery (P=0.011, P=0.002, and P=0.022) in the study group compared to those in the control group.

RESUMEN

PURPOSE: To compare the effectiveness and complications of the different cannulation techniques for bile duct stones removal in patients with intradiverticular papilla. MATERIALS AND METHODS: The records of 472 patients with common bile duct (CBD) stones who underwent endoscopic retrograde cholangiopancreatography (ERCP) procedures for bile duct stones removal from January 2014 to December 2016 were retrospectively reviewed. A total of 42 patients with CBD stones were included in the study and data of included patients were collected retrospectively. The outcomes and complications of ERCP procedures were compared. RESULTS: Of 42 ERCP procedures included in the study, patients were divided into Two-devices-in-one-channel group (n=20) and Endoclip group (n=22). The success rate of CBD cannulation at first attempt in Two-devices-in-one-channel and Endoclip groups was 85.0% (17/20) and 54.5% (12/22), respectively (P<0.05). The average time it took to cannulation in Endoclip group was much longer than that in Two-devices-in-one-channel Group (17.55±2.06 vs. 10.6±2.75 min, P<0.05). Overall complications occurred in 3 cases of Two-devices-in-one-channel group and in 4 cases of Endoclip group, respectively (15.0% vs. 18.2%, P>0.05). There was no statistically significant difference between groups regarding the complications. CONCLUSIONS: Two-devices-in-one-channel and Endoclip techniques are both safe and effective for bile duct cannulation in patients with intradiverticular papilla.

RESUMEN

AIM: Hypersplenism can occur in patients with Wilson's disease (WD). Surgical splenectomy is a conventional treatment for this condition; however, emotional and neurological deterioration may follow splenectomy. In recent years, partial splenic embolization (PSE) has been increasingly performed as a nonsurgical alternative treatment for hypersplenism. The aim of this study was to evaluate the effectiveness and safety of PSE compared with splenectomy in the treatment of hypersplenism in WD patients. METHODS: Fifty WD patients with hypersplenism were randomly divided into two groups (group A and group B), each including 25 patients. Patients in groups A and B were treated with PSE and splenectomy, respectively. Data were collected on the clinical efficacy of each procedure, adverse reactions, hematologic and blood chemistry test results, and abdominal computed tomography (CT) scan findings (group A only). RESULTS: Marked improvements in the platelet and leukocyte counts after PSE and splenectomy were observed in all patients. PSE was associated with improved liver function without severe complications, and no significant changes in emotional and neurological symptoms were observed. In contrast, seven WD patients suffered neurological deterioration after splenectomy. CONCLUSIONS: Hypersplenism in WD patients was successfully treated by PSE, which appears to be a safe and effective alternative treatment for WD-induced hypersplenism.

RESUMEN

Objective To observe the effect of Qihuang Decoction (QHD) on the intestinal muco- sal immunologic barrier of rats after gastric resection. Methods Sixty Wistar rats were randomly divided into the sham-operation group, the model group, and the QHD group, 20 in each group. Rats in the model group and the QHD group received gastric resection. Intestinal dripping Nutrison (an intacted protein en- teral nutrition powder). was given to rats in the model group after resection. Intestinal dripping Nutrison and QHD was given to rats in the QHD group. Rats in the sham-operation group only received abdominal midsection and suture. They ate and drank normally with no drug or nutrition intervention. After one-week intervention, Peyer's patches (PPs) , lamina propria lymphocytes (LPLs) , intraepithelial lymphocytes (IELs) , secretory IgA (sIgA) were isolated from rat small intestine. Ratios of αßT cell antigen receptor (αßTCR) -cluster of differentiation 3 positive (CD3+ ) , cluster of differentiation 4 positive (CD4 +) , clus- ter of differentiation 8 positive (CD8 +) , counts of IgA + B lymphocytes, and contents of intestinal mucosa sIgA were detected using flow cytometry, immunohistochemistry, and double antibody-PEG radioimmu- noassay. Results Compared with the sham-operation group, contents of intestinal mucosa sIgA, counts of IgA +B lymphocytes in PPs, and counts of lgA B lymphocytes in LPLs all decreased (P <0. 01) ; CD3 + and CD8 +T ratios in IELs, CD3 +, CD4 +, and CD8 +ratios in LPLs; CD3 + and CD4 + ratios in PPs de- creased (P <0. 01, P <0. 05) in the model group. Compared with the model group, contents of intestinal mucosa slgA, counts of IgA+B lymphocytes in PPs, and counts of IgA + B lymphocytes in LPLs all in- creased in the QHD group (P <0. 01 , P <0. 05) ; CD3 + and CD8 +T ratios in IELs, CD3 + and CD4 + ratios in LPLs, CD3+ and CD4+ ratios in PPs increased in the QHD group (P <0. 01, P <0. 05). Conclusion QHD could promote differentiation and multiplication of CD3 + , CD4 +, CD8 + T, and IgA + B lymphocytes in the intestinal mucosal immunologic barrier, increase contents of intestinal mucosa slgA, and promote the recovery of intestinal mucosal immunologic barrier of gastric resection rats.

RESUMEN

PURPOSE: This article aimed to clarify the effectiveness and the efficiency of the rendezvous technique for patients with common bile duct stones. METHODS: Four databases were searched on associations with rendezvous treatment. Six randomized controlled trials were evaluated for their success rate, stone clearance, morbidity, mortality, conversions, hospital stay, operating time, and hospitalization charges. RESULTS: This meta-analysis suggested no significant difference between the rendezvous group and the sequence group in the success rate and the stone clearance, but showed significant differences in the morbidity [odds ratio (OR)=0.54; 95% confidence intervals (CI), 0.30, 0.96], conversions (OR=0.40; 95% CI, 0.16, 0.97), the length of hospital stay (OR=-1.97; 95% CI, -2.29, -1.66), and the operating time (OR=12.95; 95% CI, 7.66, 18.24). CONCLUSIONS: The rendezvous technique is as effective as sequential endoscopic management for patients with common bile duct stones in its success rate and stone clearance, but the former is preferred in terms of morbidity, hospital stay, and hospitalization charges.

RESUMEN

BACKGROUND: Appropriate expression and regulation of the transcriptome, which mainly comprise of mRNAs and lncRNAs, are important for all biological and cellular processes including the physiological activities of bone microvascular endothelial cells (BMECs). Through an intricate intracellular signaling systems, the transcriptome regulates the pharmacological response of the cells. Although studies have elucidated the impact of glucocorticoids (GCs) cell-specific gene expression signatures, it remains necessary to comprehensively characterize the impact of lncRNAs to transcriptional changes. METHODS: BMECs were divided into two groups. One was treated with GCs and the other left untreated as a paired control. Differential expression was analyzed with GeneSpring software V12.0 (Agilent, Santa Clara, CA, USA) and hierarchical clustering was conducted using Cluster 3.0 software. The Gene Ontology (GO) analysis was performed with Molecular Annotation System provided by CapitalBio Corporation. RESULTS: Our results highlight the involvement of genes implicated in development, differentiation and apoptosis following GC stimulation. Elucidation of differential gene expression emphasizes the importance of regulatory gene networks induced by GCs. We identified 73 up-regulated and 166 down-regulated long noncoding RNAs, the expression of 107 of which significantly correlated with 172 mRNAs induced by hydrocortisone. CONCLUSIONS: Transcriptome analysis of BMECs from human samples was performed to identify specific gene networks induced by GCs. Our results identified complex RNA crosstalk underlying the pathogenesis of steroid-induced necrosis of femoral head.

RESUMEN

BACKGROUND: The purpose of this article was to clarify the optimal management concerning transjugular intrahepatic portosystemic shunts (TIPSs) and surgical shunting in treating portal hypertension. METHODS: All databases, including CBM, CNKI, WFPD, Medline, EMBASE, PubMed and Cochrane up to February 2014, were searched for randomized controlled trials (RCTs) comparing TIPS with surgical shunting. Four RCTs, which were extracted by two independent investigators and were evaluated in postoperative complications, mortality, 2- and 5-year survival, hospital stay, operating time and hospitalization charges. RESULTS: The morbidity in variceal rehemorrhage was significantly higher in TIPS than in surgical shunts (odds ratio [OR] = 7.45, 95% confidence interval[CI]: (3.93-14.15), P < 0.00001), the same outcomes were seen in shunt stenosis (OR = 20.01, 95% CI: (6.67-59.99), P < 0.000001) and in hepatic encephalopathy (OR = 2.50, 95% CI: (1.63-3.84), P < 0.0001). Significantly better 2-year survival (OR = 0.66; 95% CI: (0.44-0.98), P = 0.04) and 5-year survival (OR = 0.44; 95% CI: (0.30-0.66), P < 0.00001) were seen in patients undergoing surgical shunting compared with TIPS. CONCLUSIONS: Compared with TIPS, postoperative complications and survival after surgical shunting were superior for patients with portal hypertension. Application of surgical shunting was recommended for patients rather than TIPS.

RESUMEN

BACKGROUND AND AIM: The aim of the present study was to compare the effectiveness and complications of the double-guidewire technique (DWT) with the transpancreatic sphincterotomy (TPS) technique. METHODS: From January 2013 to December 2014, 366 consecutive endoscopic retrograde cholangiopancreatography (ERCP) procedures were carried out. Of 366 procedures, 354 procedures were carried out in patients with native major papilla biliary cannulation. A total of 279 consecutive therapeutic ERCP were included in the study and data of included patients were collected retrospectively. One hundred and thirty-seven procedures (49.1%) were done with DWT and 142 procedures (50.9%) were done with TPS for patients with difficult cannulation. The results and complications of ERCP were compared. RESULTS: Success rate of first-attempt cannulation was 62.0% in the DWT group and 81.0% in the TPS group (P = 0.00). Final rate of successful cannulation of the two biliary cannulation techniques was 86.9% and 90.8%, respectively (P = 0.09). Cannulation time in the DWT group was 7.8 ± 1.7 min compared with 3.7 ± 2.3 min in the TPS group (P = 0.00). Overall incidence of post-ERCP pancreatitis (PEP), hemorrhage, perforation and cholangitis was 1.8%, 1.1%, 0.4% and 1.1%, respectively. Adverse event rate was 2.19% in the DWT group and 7.04% in the TPS group (P = 0.04). CONCLUSIONS: DWT and TPS procedures were safe and effective. Overall cannulation rate was similar between the groups. Although DWT had a longer cannulation time, it could be considered the preferred technique in patients with failed standard cannulation for lower adverse event rate.

RESUMEN

OBJCETIVE: To investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro. METHODS: From October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells. RESULTS: The number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs. CONCLUSION: It was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

RESUMEN

OBJECTIVE: To explore whether a tissue-engineered construct composed of autogenous endothelial cells, osteoblasts and a new bioresorbable nano-hydroxyapatite/recombinant human-like collagen/polylactic acid (nHA/RHLC/PLA) would enhance bone regeneration and repair femoral head defects in canine models. METHODS: The bone marrow stem cells (BMSCs) were isolated from bone marrow of canine ilium and cultured in Dulbecco's modified eagle medium:nutrient mixture F-12 culture media for 1 week and the second-generation BMSCs were further induced by osteogenic medium (1×10(-8) mol/L dexamethasone, 10 mmol/L B-sodium glycerophosphate and 50 µg/ml vitamin C) and by endothelial cell grow medium (vascular endothelial growth factor and basic fibroblast growth factor) for 14 days in vitro. Thus BMSCs were induced into ECs and OBs. After the second passage, cells were digested and collected.And cell density was adjusted to 1.0×10(6)/ml.The cells and nHA/RHLC/PLA scaffold were co-cultured for 2-4 hours then nHA/RHLC/PLA scaffold composites prepared. Cavity defects of 8 mm in diameter and 10 mm in height were made in femoral heads.The nHA/RHLC/PLA scaffold composited with ECs and osteoblasts (OBs) (group A) and composited with OBs (group B) were inserted into different defects while cell-free nHA/RHLC/PLA scaffold served as controls (group C). New bone formation and defect repair were evaluated at 3 and 6 months by radiographic examination, histology and bone histomorphometry. RESULTS: New bone formation was evident as early as 3 months in groups A, B and C.At 6 months, abundant bone tissue within defects was observed in group A. The control animals with cell-free scaffold showed less bone formation at both timepoints.The scaffold of nHA/RHLC/PLA was degraded and absorbed gradually with the formation of new bone tissues.Histology and bone histomorphometry further revealed significantly increased trabecular bones in group A compared with groups B and C at 6 months postimplantation (P < 0.01). CONCLUSION: More abundant new bone tissue may be found in the bone defect areas implanted with osteoblast-endotheliocyte composite than osteoblasts composite and scaffold materials only.ECs and osteoblasts derived from BMSC are ideal seed cells for repairing femoral head defects.

RESUMEN

OBJECTIVE: To observe the effect of Qihuang Decoction (QHD) on mRNA expression of apoptosis genes Bcl-2, Bax, and signal transduction molecules Caspase-3, 9 in intestinal mucosa epithelium of ischemia/ reperfusion (I/R) injured rats. METHODS: Forty Wistar rats were randomized equally into 4 groups, the control group, the model group, the glutamine group, and the QHD group. Rats in the latter two groups were gastric infused with glutamine and QHD respectively for 3 days, but saline was infused instead to rats in the control group and model group. After then, except those in the control group intervened only by sham operation, rats were made into I/R injured model by 45 min occlusion of superior mesenteric artery followed by 1 h reperfusion. Immediately after modeling, mRNA expressions of Bcl-2, Bax, Caspase-3, and Caspase-9 in intestinal mucosa epithelium of rats were detected by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Compared with the control group, mRNA expressions of Bcl-2, Bax, Caspase-3 and Caspase-9 were higher in the other three groups (P < 0.05). Compared with the model group, Bcl-2 mRNA expression was higher, while the expressions of the other three indices were lower in both the glutamine group and the QHD group (P < 0.05); and comparisons between the glutamine group and the QHD group showed a more depressed Bax mRNA expression (0.281 +/- 0.087 vs 0.350 +/- 0.053) and higher Bcl-2/Bax ratio (1.648 vs 1. 374) in the QHD group. CONCLUSIONS: QHD can reduce the I/R injury in the intestinal mucosa epithelium by inhibiting the cell apoptosis. The mechanism may be correlated with increased Bcl-2 mRNA expressions and decreased mRNA expressions of Bax, Caspase-3 and Caspase-9.

RESUMEN

<p><b>OBJECTIVE</b>To study the effect of laminarin sulphate (LAMS) on the expressions of PTEN and P27kip1 in androgen-independent prostate cancer PC-3 cells in vitro, and investigate the mechanism of its anti-tumor action.</p><p><b>METHODS</b>The inhibitory effects of different concentrations of LAMS (0, 50, 100, 200 microg/ml) on androgen-independent prostate cancer PC-3 cells were detected by WST-8 assay. The morphology of PC-3 cells was observed under the fluorescence microscope, and the cell cycle and apoptosis were analyzed by flow cytometry. The mRNA and protein levels of PTEN and P27kip1 were measured by RT-PCR and Western blot.</p><p><b>RESULTS</b>LAMS inhibited the proliferation of androgen-independent prostate cancer PC-3 cells in a dose- and time-dependent manner, and the cell cycle analysis showed that PC-3 cells were arrested in the S phase after treated with different concentrations of LAMS. The rate of apoptosis was increased and many typical apoptotic morphological features were observed under the fluorescence microscope. The PTEN and P27kip1 expressions at mRNA and protein levels were increased in a dose-dependent manner.</p><p><b>CONCLUSION</b>LAMS can inhibit the proliferation, arrest the cell cycle in the S phase and induce apoptosis of prostate cancer PC-3 cells. The significantly increased expressions of PTEN and P27kip1 may be one of the mechanisms for LAMS inhibiting prostate cancer PC-3 cells.</p>

RESUMEN

OBJECTIVE: To observe the effect of Qihuang Decoction (QHD) on epithelial cell apoptosis of ischemia-reperfusion (I/R) injured intestinal mucosa in rat. METHODS: The I/R injured intestinal mucosa rat model was established by clamping superior mesenteric artery (SMA) for 45 min and reperfusing for 60 min. The pathomorphological Changes and epithelial cell apoptosis in the injured intestinal mucosa were observed and compared among groups: the sham-operated group (A), the model group (B), the glutamine treated group (C) and the QHD treated group (D). RESULTS: pathomorphological examination showed that in group A, the intestinal villus was intact; in group B, the intestinal subepithelial space were dilated, and showed evident cleavage between the epithelial top and the lamina propria with bare capillaries, bleeding and ulceration; in group C and D, the above-mentioned pathomorphological changes were alleviated to some extents, appeared only in part of the villa, and the alleviation was more significant in group D than in group C. Chiu's scoring showed that the lowest score (zero) presented in group A and the highest presented in group B; scores in group C and D was significantly lower than that in group B (P < 0.05), but showed insignificant difference between the two groups (P > 0.05). Epithelial cell apoptosis detection showed that the least apoptosis rate presented in group A, and the highest in the group B; while in the group C, it lied between group A and B (all P < 0.05), and showed no statistical significance to group D (P > 0.05), though appeared a lowering trend. CONCLUSION: QHD could reduce the I/R injured intestinal epithelial mucosa, and its protective mechanism may be related to the inhibition on apoptosis of intestinal mucosal epithelial cells.

RESUMEN

OBJECTIVE: To explore the regulation and clinical significance of intestinal dripping of Jianpi Tongli (JPTL) Chinese herbs on levels of serum cytokines, such as interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R) and interleukin-12 (IL-12) in treating patients with gastric cancer (GC) at early post-operational stage. METHODS: Sixty patients with GC were randomly divided into two groups, i. e. the studied group (n = 30), treated with JPTL Chinese herbs, and the control group (n = 30) treated with normal saline. The medication was started from the 1st day after operation by intestinal dripping daily, 7 days as one course. Levels of IL-2, sIL-2R and IL-12 were observed before and after operation. RESULTS: Significant difference was seen on the 7th day post-operation between the studied and the control group, mainly in aspects of obvious increase of IL-2 and decrease of sIL-2R (P <0.05), no significant difference in IL-12 was found (P >0.05) though there was certain improvement. Compared with pre-operation of the same group, significant difference was found in the studied group in the increased IL-2 and IL-12 and decreased sIL-2R on the 7th day post-operation, while no significant difference in these indexes was found in the control group (P >0.05), though certain improvement was shown. CONCLUSION: Early intestinal dripping of JPTL Chinese herbs to post-operational patients with GC could improve their immune function, which was of important significance in early preventing the severe complications, improving the prognosis, and elevating the survival rate.
