ABSTRACT

To investigate the potential molecular mechanism of the combination of Platycodonis Radix and Lilii Bulbus with the homology of medicine and food in the treatment of pneumonia by means of network pharmacology and in vitro verification experiment. Under the condition of bioavailability(OB)≥30% and drug-like(DL)≥0.18, the active components of Platycodonis Radix and Lilii Bulbus were screened in TCMSP database; the prediction targets of active components were searched from TCMSP, DrugBank and other databases, and the potential targets of pneumonia were obtained through GeneCards and OMIM database. The common targets were obtained by the intersection of drug and disease targets. The PPI network of common targets was constructed by STRING 11.0, and the core targets were obtained by topological analysis. Then the core targets received GO and KEGG analysis with use of WebGestalt and Metascape. The "component-target-pathway" network was constructed with the help of Cytoscape 3.7.1 software, and the component-target molecular docking verification was carried out with Discovery Studio 2016 software. Finally, the core targets and pathways were preliminarily verified in vitro. In this study, 12 active components were screened, 225 drug prediction targets and 420 potential diseases targets were obtained based on data mining method, and 14 core targets were obtained by topological analysis, including TNF, MMP9, AKT1, IL4 and IL2. The enrichment results of GO and KEGG showed that "Platycodonis Radix and Lilii Bulbus" drug pair may regulate inflammation, cell growth and metabolism by acting on 20 key signaling pathways such as TNF and IL-17, thereby exerting anti-pneumonia effects. The results of molecular docking showed that 12 active components had good binding ability with 14 core targets. In vitro experiment results showed that the core components of "Platycodonis Radix and Lilii Bulbus" drug pair could inhibit the expression of MMP9 and TNF-α by regulating TNF signal pathway. This study confirmed the scientificity and reliability of the prediction results of network pharmacology, and preliminarily revealed the potential molecular mechanism of the compatibility of Platycodonis Radix and Lilii Bulbus in the treatment of pneumonia. It provides a novel insight on systematically exploring the mechanism of the compatible use of Platycodonis Radix and Lilii Bulbus, and has a certain reference value for the research, development and application of new drugs.

ABSTRACT

Objective:To explore the clinical significance and underlying mechanism of changes in serum IL - 18 and IL - 1 beta after trauma.Methods:Enzyme-linked immunosorbent assay was used to detect the levels of IL-18 and IL-1β in trauma patients and healthy controls. The differences in serum IL-18 and IL-1β levels were compared between the two groups, and the levels of IL-18 and IL-1β in the traumatic subgroups were further compared.Results:The serum levels of IL-1β and IL-18 of trauma patients were 80±2.0 pg/mL and 27±3.0 pg/mL, respectively, which were significantly higher than those in healthy controls ( P < 0.01). Serum levels of IL-1β and IL-18 showed an upward trend on the 3rd day after trauma. There were also statistically significant differences within the trauma subgroups ( P < 0.01). Conclusions:The serum levels of IL-18 and IL-1β of post-traumatic patients are increased, indicating that NLRP3 inflammasomes are activated in peripheral blood cells in the early stage of trauma, which aggravates the inflammatory response. The AIS-ISS score is positively correlated with the expression levels of IL-18 and IL-1β in serum, indicating that the more severe the injury, the more severe the inflammatory response.

ABSTRACT

OBJECTIVE: To establish a novel standardized magnetization transfer ratio (MTR) parameter which considers the element of the normal bowel wall and to compare the efficacy of the MTR, normalized MTR, and standardized MTR in evaluating intestinal fibrosis in Crohn's disease (CD).MATERIALS AND METHODS: Abdominal magnetization transfer imaging from 20 consecutive CD patients were analyzed before performing elective operations. MTR parameters were calculated by delineating regions of interest in specified segments on MTR maps. Specimens with pathologically confirmed bowel fibrosis were classified into one of four severity grades. The correlation between MTR parameters and fibrosis score was tested by Spearman's rank correlation. Differences in MTR, normalized MTR, and standardized MTR across diverse histologic fibrosis scores were analyzed using the independent sample t test or the Mann-Whitney U test. The area under the receiver operating characteristic curve (AUC) was computed to test the efficacies of the MTR parameters in differentiating severe intestinal fibrosis from mild-to-moderate fibrosis.RESULTS: Normalized (r = 0.700; p < 0.001) and standardized MTR (r = 0.695; p < 0.001) showed a strong correlation with bowel fibrosis scores, followed by MTR (r = 0.590; p < 0.001). Significant differences in MTR (t = −4.470; p < 0.001), normalized MTR (Z = −5.003; p < 0.001), and standardized MTR (Z = −5.133; p < 0.001) were found between mild-to-moderate and severe bowel fibrosis. Standardized MTR (AUC = 0.895; p < 0.001) had the highest accuracy in differentiating severe bowel fibrosis from mild-to-moderate bowel wall fibrosis, followed by normalized MTR (AUC = 0.885; p < 0.001) and MTR (AUC = 0.798; p < 0.001).CONCLUSION: Standardized MTR is slightly superior to MTR and normalized MTR and therefore may be an optimal parameter for evaluating the severity of intestinal fibrosis in CD.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the outcome of Titanium Elastic intramedullary nailing(TEN) for the treatment of refracture of clavicle.</p><p><b>METHODS</b>From March 2010 to March 2016, 9 cases of clavicle fracture, postoperative re-fracture (plate broken before fracture healing, plate and screw pull out or refracture after fracture union and internal fixation removal) included 6 males and 3 females with a mean age of 38.6 years old ranging from 20 to 62 years old; 3 cases were sports injury, 5 cases were traffic injury, 1 case was severe injury. All cases were closed fractures, and 2 cases were multiple fractures. According to OTA(Orthopaedic Trauma Association classification), 2 cases were 06-A1, 1 case was 06-A2, 1 case was 06-A3, 2 cases were 06-B1, 2 cases were 06-B2, and 1 case was 06-B3. Among them, 4 cases were treated with AO titanium elastic intramedullary nail (TEN), and 5 cases of early internal fixation failure of clavicle fracture were treated with plate and screw internal fixation plus bone graft. The time of bone union, VAS score and Constant Shoulder Score were observed and recorded.</p><p><b>RESULTS</b>All incisions healed at stage I without infection. All 9 patients were followed up for a period of 14 months. All patients' implants were removed at 12 months after the second operation without refractures. The Constant score of shoulder joint was from 64 to 94 at 4 weeks after the second operation, 91 to 100 at 4 weeks after implants removal. The average bone healing time was 4.3 months from 3 to 6 months. The pain VAS score decreased significantly and the pain was relieved significantly.</p><p><b>CONCLUSIONS</b>Titanium elastic intramedullary nail (TEN) for the treatment of clavicle fracture after internal fixation of refracture patients can be achieved better outcomes, less trauma, good fracture healing, good postoperative recovery of shoulder joint function, but need to pay attention to the reasonable selection of patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the stability of internal fixation for femoral neck fracture(FNF) using two or three cannulated screws directed to different fracture lines, and to provide a theoretical basis for the clinical decision making.</p><p><b>METHODS</b>Fifteen fresh frozen human femur samples were selected and the FNF model was established with Pauwels angle of 30°, 50° and 70° respectively. The models were fixed with three or two cannulated screws, and their differences at tensile strength, subsidence, shear strength and composite displacement, gap distance, torsional angle and stiffness values of four types of femur were evaluated to identify their biomechanical stability.</p><p><b>RESULTS</b>With Pauwels angle of 30° and 50°, no statistical differences at the referenced outcomes were observed between two and three cannulated screw fixation for FNF(>0.05). With the Pauwels angle of 70 °, three cannulated screws fixation were significantly superior to two cannulated screws fixation for FNF(<0.05). Nevertheless, when Pauwels angle was 70°, three cannulated screws fixation turned out to be relative instable compared with Pauwels angle of 30° and 50°.</p><p><b>CONCLUSIONS</b>With Pauwels angle of 30° and 50°, two cannulated screws fixation was similarly stable as using three cannulated screws for FNF. Three cannulated screws fixation were obviously superior to two cannulated screws fixation when Pauwels angle was 70°, but the application of three cannulated screws could still be insufficiently stable when only such routine fixations were utilized. Therefore, Angle Stabilizing System or anti-sliding screws were needed to enhance the stability of FNF fixation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the outcome of Titanium elastic intramedullary nailing (TEN) for the treatment of displaced midclavicular fractures.</p><p><b>METHODS</b>Between February 2010 and February 2013, 62 patients with displaced midclavicular fractures were treated by TEN, including 27 males and 35 females with an average age of 37.6 years old ranging from 15 to 67 years. The course of disease was from 1 to 9 days (means 2.7 days). Thirty-nine cases were treated by closed reduction and 23 cases by assistant small incision. Based on OTA (the Orthopaedic Trauma Association classification) classification, 31 cases of simple fractures involved 5 cases of 06-A1,15 cases of 06-A2,11 cases of 06-A3; 31 cases of wedge fractures involved 4 cases of 06-B1,12 cases of 06-B2,15 cases of 06-B3. Postoperative pain relief were evaluated by VAS score,and operation time,fracture healing time were recorded. After 6 weeks and after removing internal fixation shoulder joint function was evaluated by Constant score, and shoulder joint function were assessed by Herscovici score after 6 weeks.</p><p><b>RESULTS</b>Except 2 cases were lost to follow-up, 2 cases did not remove internal fixation, 3 cases' fractures were nonunion, the remaining 55 patients received follow-up for an average time of 11.4 months. The average preoperative VAS score was 5.20±0.71, and it turned to be 1.550.59 at 3 days after operation. The average operative duration was 40 min (15 to 65 min). The average bone healing time was (2.71±0.54) months (2 to 5 months). No difference about bone healing time was found between simple fractures and wedge fractures,and between the patients treated by closed reduction and assistant small incision. According to Herscovici standard, the shoulder function was excellent in 49 cases, good in 4, fair in 1, and poor in 1. Simple fractures achieved better Constant score than wedge fractures at 6 weeks postoperatively, whereas no difference was found at 4 weeks after fixation removal.</p><p><b>CONCLUSION</b>Titanium elastic nails (TEN) for treatment of displaced midclavicular fractures has advantages of good clinical effect,rapid pain relief,fast recovery of shoulder joint function. For OTA classification type B patients with comminuted fracture can replace steel to achieve very good effect, but to grasp the appropriate.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the cause of failure after autogenous bone graft with limb fracture nonunion,to explore the major influencing factor of the treatment, and to research the evidence for improving the treatment of nonunion.</p><p><b>METHODS</b>A retrospective analysis was done with 367 cases suffering from autogenous bone graft surgery after limb fracture nonunion between January 1995 to December 2011. Among them,there were 198 males and 169 females aged 12 to 89 years (means 53.5 years) with duration of 23 to 49 months. The treatment effect assessed with X-ray and CT after grafting in the treatment, and 32 cases were detected nonunion again, and others' fixations were dismantled by operation after fracture healing. The following correlation including factorsages,gender,smoking, nutritional status during therapy,classification of primary fracture,location of fracture, type of nonunion, changing the type of fixation,type of fixation and complicating disease were evaluated by Logistic stepwise regression to discover the influencing factors of the failure of union.</p><p><b>RESULTS</b>The treatment failure rate was 8.72% in the patients with surgery and graft included in the statistics for the late re-admitted in 6 to 12 months followed-up. Smoking, classification of primary fracture, type of nonunion, changing the type of fixation, complicating disease had influence to incidence rate of union after autogenous bone graft.</p><p><b>CONCLUSION</b>Autogenous bone graft is the utility method for limb fracture nonunion. Smoking, classification of primary fracture, classification of nonunion,changing the type of fixation, complicating disease are the risk factors of nonunion after graft. Patients should be advised to stop smoking in the nonunion bone graft. And at the same time, the treatment of related diseases, analysis of the original fracture and nonunion,aggressive treatment of infection, and developing better surgical solutions before surgery, as well as changing the fixation methods can reduce the risk of failure of the graft.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of postoperative intraportally administration of insulin on hepatic regeneration in adult patients underwent living donor right lobe liver transplantation (LDLT).</p><p><b>METHODS</b>From July 2005 to September 2007, 15 right lobe LDLT adult recipients voluntarily receiving posttransplant intraportal insulin administration, without postoperative vascular and bile duct complications, without immune rejection, with more than 1 month survival and complete clinical data were enrolled in this study as intraportal insulin-therapy group (Group I). Another consecutive 15 right lobe LDLT adult recipients meeting the upwards referred criteria were enrolled in as non-insulin-therapy control group (Group NI). Recipients in Group I were treated postoperatively with intraportal insulin infusion, as follows: a 18-gauge catheter was inserted into right gastro-omental vein during surgery, regular insulin was administered just after the operation at the rate of 2 units/hour for 7 days. Liver function and serum insulin level were measured at before-operative day 1, postoperative day (POD) 7 and 30. Graft volume (GV) were measured during operation, and at POD 7 and 30.</p><p><b>RESULTS</b>The rate defined as ratio of POD 7 GV/operation GV in Group I was higher than that of Group NI [(186.1 +/- 35.4)% vs. (160.6 +/- 22.1)%, P < 0.05]. The rate defined as ratio of POD 7 GRWR/operation GRWR was also higher in Group I than Group NI [(179.0 +/- 35.8) % vs. (156.6 +/- 18.5%, P < 0.05], whereas significant differences were not appeared between two groups in terms of regeneration rates at POD 30. Serum levels of total bilirubin, aspartate aminotransferase and alanine aminotransferase in Group I were lower than that in Group NI at POD 7 (P < 0.05). Significant differences were not presented between two groups in terms of post-transplant serum insulin levels and total insulin dosage by subcutaneous administration and venous injection (P > 0.05).</p><p><b>CONCLUSIONS</b>These results suggest that intraportal insulin administration could augment liver graft regeneration during the first postoperative week.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the techniques for excision and reconstruction of anomalous portal venous branches (APVB) in adult-to-adult right lobe living donor liver transplantation (A-A RL LDLT).</p><p><b>METHODS</b>From February 2002 to April 2007, 70 cases of A-A RL LDLT were performed. Preoperative three-dimensional computed tomography of the donor revealed the configurations of hepatic artery, portal vein and hepatic vein. Nine donors had anomalous portal venous branching (APVB). The APVB were type II (trifurcation) in 7 cases and type III in two. Except the excision of APVB with a common opening by a narrow bridge of main portal vein tissue in one type II donor, all the right APVB were transected on the principal of donor priority: right APVB being excised approximately 2-3 mm from the confluence while leaving the donor's portal vein intact. In type II APVB, the donor portal venous branches were transected with separate two openings and reconstructed as double anastomoses in 4 cases, with separate two openings joined as a common orifice at the back table and reconstructed as single anastomoses in 2 cases, and with one common opening with narrow-bridge of tissue and reconstructed as single anastomoses in 1 case. In type III APVB, the APVB were transected with separate two openings and were reconstructed by double anastomoses in 1 case and by a new technique named U-shaped vein graft interposition in the another one.</p><p><b>RESULTS</b>There were no vascular complications such as portal vein stricture or thrombosis, hepatic artery stricture or thrombosis and hepatic vein outflow stricture in all 9 recipients transplanted with grafts with APVB. Only the type II APVB donor undergoing a excision of APVB with a common opening by a narrow bridge of main portal vein tissue developed portal vein thrombosis on the third postoperative day and underwent thrombectomy followed by repair with vein patch plasty. The velocity of blood flow in the U-graft was normal.</p><p><b>CONCLUSIONS</b>It is feasible and safe of APVB excision on the principal of donor priority and reconstruction including double anastomoses and the novel U-graft interposition in A-A RL LDLT, and has a good outcome without increasing the management difficulty.</p>

ABSTRACT

<p><b>OBJECTIVE</b>The aim of this study was designed to evaluate the outcomes of liver transplant recipients with chronic hepatitis B (CHB) receiving either lamivudine monotherapy or lamivudine combined with individualized low-dose hepatitis B immunoglobulin (HBIG) therapy.</p><p><b>METHODS</b>A total of 111 liver transplant recipients with CHB were divided not randomly into two groups according to the availability of HBIG before liver transplantation (LT). Thirty-two patients received lamivudine monotherapy (100 mg/d) and 79 patients received lamivudine (100 mg/d) combined with individualized low-dose HBIG (intramuscular administration) to maintain the titer of antibody to hepatitis B virus (HBV) surface antigen (anti-HBs) not less than 100 U/L. The patients were followed-up for a median time of 32 months (1 to 88 months).</p><p><b>RESULTS</b>In the lamivudine monotherapy group, 5 patients hepatitis B relapsed (3/5 developed YMDD mutants of HBV), with 1-, 2-, and 3-year cumulative recurrence rates of 7.1%, 14.3% and 17.9% and survival rates of 87.5%, 84.4% and 74.6%. In the lamivudine and HBIG combination therapy group, 2 patients hepatitis B relapsed (2/2 developed YMDD mutants of HBV), with 1-, 2-, and 3-year cumulative recurrence rates of 0, 1.8% and 5.7% (P < 0.01) and survival rates of 83.5%, 80.9% and 77.6% (P > 0.05).</p><p><b>CONCLUSIONS</b>Compared with lamivudine monotherapy, lamivudine combined with individualized low-dose HBIG can further reduce the recurrence risk of hepatitis B in liver transplant recipients. This combined therapy could be used as a rational strategy for prophylaxis of hepatitis B recurrence in such patients.</p>
