The effects on rat’s liver preservation using HX solation with high potassium and low sodium or HXm solution with high sodium and low potassium were studied with isolated perfusion of rat livers (IPRL). Sixty inbred Wistar rats were randomly divided into group HX (preserved with HX solution, n=30) and group HXm (preserved with HXm solution,n=30). The preservation effects of the storage solutions were assessed by measuring the sinunoidal lining cell mortality (SLCM), the Krebs-hense-leit perfusate ketone bidy ratio (PKBR), the hepatic sugar release (SL), and the hepatic tissue water content (HTWC). The results showed that there no significant differences between the two storage solutions after 6 hours preservation. If the preserved time was prolonged to 12 hours or more, the effect of rat’s liver preservation using HX solution were much superior to those using HXmsolutin.
Objective To develop a diclofenac sodium-loaded gelatin scaffold with anti-inflammatory activity and provide a new avenue for alleviating the inflammatory response and enhancing cartilage regeneration in vivo. Methods Diclofenac sodium was homogeneously mixed with gelatin to prepare a diclofenac sodium-loaded porous gelatin scaffold by freeze-drying method as the experimental group, and a pristine porous gelatin scaffold was served as a control group. The general morphology of the scaffold was observed, the pore size of the scaffold was measured by scanning electron microscopy, the porosity of the scaffold was calculated by drainage method, the loading of diclofenac sodium into the gelatin scaffold was detected by fourier transform infrared spectrometer and X-ray diffraction examinations, and the release kinetics of diclofenac sodium from gelatin scaffold was tested using an in vitro release assay. The two scaffolds were co-cultured with lipopolysaccharide-predisposed RAW264.7 in vitro, and the expressions of interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) were detected by reverse transcription polymerase chain reaction (RT-PCR), enzyme-linked immuno sorbent assay, and Western blot, to detect the in vitro anti-inflammatory effect of the drug-loaded scaffold. Thereafter, the second generation chondrocytes of New Zealand white rabbits were inoculated on the two groups of scaffolds for in vitro culture, and the cytocompatibility of the scaffold was tested by live/dead staining and cell counting kit 8 assay, the feasibility of in vitro cartilage regeneration of the scaffold was evaluated via gross observation, HE staining, Safranin-O staining, and immunohistochemical collagen type Ⅱ staining, as well as biochemical quantitative analyses. Finally, the two groups of chondrocyte-scaffolds were implanted subcutaneously into New Zealand white rabbits, and after 4 weeks, the general observation, HE staining, safranin O staining, immunohistochemical collagen type Ⅱ staining, and biochemical quantitative analyses were performed to verify the cartilage regeneration in vivo, and the expression of inflammation-related genes CD3 and CD68 was detected by RT-PCR to comprehensively evaluate the anti-inflammatory performance of the scaffolds in vivo. Results The two scaffolds exhibited similar gross, microporous structure, pore size, and porosity, showing no significant difference (P>0.05). Diclofenac sodium was successfully loaded into gelatin scaffold. Data from in vitro anti-inflammatory assay suggested that diclofenac sodium-loaded gelatin scaffold showed alleviated gene and protein expressions of IL-1β and TNF-α when compared with gelatin scaffold (P<0.05). The evaluation of cartilage regeneration in vitro showed that the number of living cells increased significantly with the extension of culture time, and there was no significant difference between the two groups at each time point (P>0.05). White cartilage-like tissue was regenerated from the scaffolds in both groups, histological observation showed typical cartilage lacuna structure and specific cartilage extracellular matrix secretion. There was no significant difference in the content of cartilage-specific glycosaminoglycan (GAG) and collagen type Ⅱ between the two groups (P>0.05). In vivo experiments showed that the samples in the experimental group had porcelain white cartilage like morphology, histologic staining showed obvious cartilage lacuna structure and cartilage specific extracellular matrix, the contents of GAG and collagen type Ⅱ were significantly higher than those in the control group, and the protein and mRNA expressions of CD3 and CD68 were significantly lower than those in the control group, with significant differences (P<0.05). ConclusionThe diclofenac sodium-loaded gelatin scaffold presents suitable pore size, porosity, and cytocompatibility, as well as exhibited satisfactory anti-inflammatory ability, providing a reliable scheme for alleviating the inflammatory reaction of regenerated cartilage tissue after in vivo implantation and promoting cartilage regeneration in vivo.
【摘要】 患者为老年男性,反复出现恶心、呕吐、乏力、低钠、低钾血症, 3次住院。对其恶心呕吐原因,曾考虑是否有抗高血压药物吲哒帕胺所引起,或是老年人摄入不足,电解质紊乱所致低钠低钾血症。最后考虑该患者低钠血症系垂体前叶功能减退所致。MRI检查显示空蝶鞍。空鞍的原因尚不清楚,空鞍综合征也是垂体前叶功能减退的因素之一。此症尽管很少见,但随着CT、MRI这些高新设备的普遍使用及人口老龄化,会发现更多的病例,也对我们诊断治疗提供了有力的依据。【Abstract】The patient’s condition: old male patient with repeat nausea, vomitus, hypodynamia, low sodium and kaliopenia. Three times to be in hospital. First, we consider that indapamide resuted low sodium and Kaliopemia,but we discovered that the anterior pituitay gland hypofunction. MRI show that empty sella turcica. The reason of empty is not clear,the saddle syndrome is also a factor of pituitary function before the leaves falling off. The disease was rare,but with common use of CT,MRI and aging,we will discover many more cases to provide power evidence for diagnosis and treatment.
ObjectiveTo compare the effectiveness of haemocoagulase agkistrodon and tranexamic acid and sodium chloride in the prevention and treatment of perioperative bleeding in a real world setting. MethodsA research database was constructed based on the records of inpatient visits using haemocoagulase agkistrodon and tranexamic acid and sodium chloride according to the SuValue® database from January 1, 2016 to December 31, 2020. The patients were divided into two groups according to the different interventions. After matching with a 1∶1 propensity score, the effectiveness of two groups was compared. ResultsA total of 858 patients were included in each of the two groups, and there was no statistically significant difference in baseline characteristics between the two groups (P>0.05). Research results showed that patients using haemocoagulase agkistrodon had significantly reduced length of hospital stay, decrease in hematocrit, average estimated surgical bleeding, and decrease in hemoglobin (P<0.01). ConclusionHaemocoagulase agkistrodon has better effectiveness than tranexamic acid and sodium chloride for reducing perioperative blood loss based on current real world evidence.
Objective To observe the short-term effect and safety of hyperbaric oxygen combined with edaravone and ozagrel sodium in treating progressive cerebral infarction. Methods A total of 65 in-patients with acute progressive cerebral infarction were randomly divided into two groups: 33 in-patients in the trial group were treated by hyperbaric oxygen combined with edaravone and ozagrel sodium, while the other 32 in-patients in the control group were treated by edaravone and ozagrel sodium. The course of treatment was 14 days. The following indications were assessed before and after the treatment respectively: the national institutes of health stroke scale (NIHSS), activities of daily living (ADL), and clinical effects. Results This study showed that the scores of both ADL and NIHSS in the trial group were higher than those in the control group, with significant differences (Plt;0.05). The clinical effective rate of the trial group was 90.91% which was obviously higher than the control group with a significant difference (P=0.028). There were no obvious adverse reactions in both groups. Conclusion Hyperbaric oxygen combined with both edaravone and ozagrel sodium is notable in short-term effect and safe, thus it is worth being popularized in clinical treatment.
Objective To systematically evaluate the effectiveness and safety of disodium cantharidinate and vitamin B6 injection plus chemotherapy compared with chemotherapy alone, in the treatment of non-small cell lung cancer (NSCLC). Methods The Cochrane Library (Issue 1, 2011), MEDLINE (1966 to November 2011), EMbase (1984 to November 2011), CBM (1978 to November 2011), CNKI (1995 to November 2011) and VIP (1989 to November 2011) were searched electronically, and the randomized controlled trials (RCTs) about disodium cantharidinate and vitamin B6 injection plus chemotherapy for NSCLC were included. The quality of the included studies was assessed and crosschecked by two reviewers independently, and meta-analyses were performed for homogeneous studies by using Cochrane Collaboration’s RevMan 5.1 software. Results Eight RCTs involving 539 patients met inclusion criteria were included in meta-analyses. The quality of all studies was in Grade B. The results of meta-analyses showed that disodium cantharidinate and vitamin B6 injection plus chemotherapy, compared with chemotherapy alone, could increase effective rate (RR=1.32, 95%CI 1.07 to 1.62) and clinical benefit rate (RR=1.24, 95%CI 1.12 to 1.37), improve quality of life (RR=2.23, 95%CI 1.55 to 3.19) and clinical symptoms (RR=1.55, 95%CI 1.24 to 1.95), increase body weight (RR=2.72, 95%CI 1.74 to 4.25), and decrease bone marrow suppression (leucocyte reduction rate) (RR=0.36, 95%CI 0.21 to 0.61). Conclusion The evidence available indicates that the treatment regimen of disodium cantharidinate and vitamin B6 injection plus chemotherapy is superior to chemotherapy alone in increasing effects and decreasing toxicity for the patients with NSCLC. More high-quality and multi-center RCTs with larger sample and longer follow-up are proposed.
Objective To study the clinical efficacy of topiramate combined with carbamazepine combined with phenytoin in elderly seizures. Methods A total of 105 elderly patients with epilepsy were enrolled in this study from August 2014 to July 2016 in Fuzhou Chinese and Western Medicine Hospital. The patients were aged 61 to 80 years. There were 42 males and 63 females with epilepsy. The course were 1 to 5 years; 55 cases were partial onset, 50 cases were systemic attack. According to the different treatment methods, the patients were divided into A, B, C three groups, each group were 35 patients. Group A was daily treated with 4 to 8 mg/kg topiramate; Group B was treated with 0.3 g carbamazepine combined with 250 to 300 mg phenytoin per day. Group C was daily treated with 4 to 8 mg/kg topiramate and 0.3 g carbamazepine combined with 250 to 300 mg phenytoin. The total effective rate, the incidence of adverse reactions, the number of seizures before and after treatment were compared among the three groups. Results The total effective rate of group C was higher than that of group A and B, and the difference was statistically significant (P<0.05). There were no significant differences in the number of epileptic seizures between the three groups before treatment (P>0.05). The number of seizures in group C was significantly lower than that in group A and B (P<0.05). Conclusions The treatment of topical epilepsy patients with topiramate and carbamazepine combined with phenytoin can significantly improve the total effective rate of treatment, protect the safety of medication, reduce the number of patients with epilepsy, so that patients can quickly return to normal life. It would be worthy for clinical promotion and use.
ObjectiveTo investigate whether parecoxib sodium preemptive analgesia reduces inflammatory cytokines and stress hormones production in elderly patients after total hip replacement. MethodSixty patients with American Society of Anesthesiologists Classification Ⅰ-Ⅱ undergoing total hip replacement for femoral neck fracture or aseptic necrosis of the femoral head, aged between 60 and 90 years with a body weight more than 50 kg, were randomly divided into preemptive analgesia group (group P, n=30) and control group (group C, n=30). The patients in group P received parecoxib sodium 40 mg intravenously 30 min before skin incision, and another 20 mg 8 hours after the first administration. All the patients in the two groups received the administration of patient-controlled analgesia sufentanyl. We recorded blood levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), cortisol (COR), adrenaline (AD) and noradrenaline (NAD) 30 min before skin incision, and 1 hour, 6 hours, 12 hours and 24 hours postoperatively. ResultsThe blood levels of IL-6, TNF-α, COR, AD and NAD in group P at 1 hour, 6 hours, 12 hours or 24 hours postoperatively were significantly lower than those in group C (P<0.05). ConclusionsParecoxib sodium preemptive analgesia reduces postoperative inflammatory cytokines and stress hormones production in elderly patients undergoing total hip replacement.
ObjectiveTo evaluate the preemptive analgesic efficiency of parecoxib on patients undergoing inguinal hernia repair. MethodsOne hundred and twenty patients scheduled for surgery between May and August 2013 were randomized into group A (n=60) and group B (n=60). Patients in group A received intravenous parecoxib sodium (40 mg) for 45 minutes before surgery while group B received equivalent normal saline. All patients underwent tension-free hernia repair under local anesthesia with simplex lidocaine. Visual analogy scores (VAS) after surgery and the maximum VAS were recorded. The number of patients requiring rescue analgesic (tramadol injection) or with adverse effects related to analgesia were observed and recorded. Postoperative hospital stay and patient satisfaction score with analgesic effect were compared between the two groups. Concentrations of plasma prostaglandin E2(PGE2) before surgery and 24 hours after surgery were measured in both groups. ResultsVAS scores were significantly lower in group A at 2, 4, 8 and 12 hours after surgery than group B, while no significant difference was seen after 24 hours of the surgery. The number of patients requiring tramadol (3/60) or with adverse effects (2/60) in group A were significantly lower than that in group B (11/60 and 8/60 respectively). Postoperative hospital stay was shorter while patient satisfaction score with analgesic effect was higher in group A than in group B. There were no significant differences in concentration of plasma PGE2 between the two groups before surgery and after 24 hours of the surgery (P>0.05). ConclusionPreemptive administration of parecoxib for hernia repair can result in significant analgesic effect with fewer adverse effects, higher patient satisfaction and faster recovery.
Objective To investigate the retinal toxicity and verify the safe dose of intravitreal injection of nonsteroid anti-inflamatory drug,diclofenac sodium.Methods Twenty-eight healthy adult white rabbits were divided at random into 7 groups and received in every right eye the intravitreal injection of a single dose of diclofenac sodium solution ranging from 0.4-0.1 mg/0.1ml respectively ,the left eyes were regarded as conreol ones.Before injection and on the 1st,3rd,7th,14th,21st,and 28th day after injection the electroretinography on both eyes was examined.On the 28th day after injection the retinas of two rabbits of every group were examined by using light microscopy.On the 10th and 30th day after injection the retinal tissues around the optic nerve sisk of two eyes from every group at random were tested by using transmission electron microscopy.Results The retio of amplitude ofb wave of electroretinography in 0.4mg and 0.5mg groups had no sighnificant difference from groups before injection,the retinal tissues showed no structural changes in light and ecectron microscopy examination.The ratio of amplitude ofb wave of photoptic electroretinogrphy in 0.6mg groups in the early stage after injection was markedly reduced（P＜0.05）and returned to that before injection with time,reversible change of the edematou retina was discovered.The ratio of amplitude of b wave of electroretinography in 0.7-1.0mg groups was distinctly descreaded after injection（P＜0.05 or P＜0.01）,the cells of all the retinal layer revealed apparent and irreversible damage.Conclusion The largest dose of safety of intravitreal diclofenac sodium should be not more than 0.6mg.The toxic effect of intravitreal diclofenac sodium on retina is concerned mostly to cones and rods.
