Radiofrequency ablation for hepatic hemangioma is safe and effective, and can obtain the same curative effect as traditional surgical resection. For hepatic hemangiomas with large volume, abundant arterial blood supply and long ablation time, systemic inflammatory response syndrome (SIRS) often occurs after radiofrequency ablation, which can lead to injury or dysfunction of important organs. This paper systematically summarizes the mechanism, prevention and treatment of SIRS after radiofrequency ablation of hepatic hemangioma, so as to provide reference for improving the safety of radiofrequency ablation of hepatic hemangioma.
ObjectiveTo investigate the feasibility and safety of non-intubation anesthesia in thoracic surgery.MethodsFrom September 2017 to December 2019, 296 patients were operated at department of thoracic surgery in our hospital. There were 167 males and 129 females with an average age of 50.69±12.95 years, ranging from 16 to 76 years. The patients were divided into two groups according to whether they were intubated: 150 patients were in a non-intubation group, including 83 males and 67 females with an average age of 49.91±13.59 years, ranging from 16 to 76 years, and 146 patients were in an intubation group including 84 males and 62 females with an average age of 51.49±12.26 years, ranging from 16 to 74 years. Intraoperative data, postoperative recovery, inflammatory response of the two groups were compared.ResultsThere was no statistical difference between the two groups in operation time, blood loss, the lowest oxygen saturation or other indicators (P>0.05). But the highest partial pressure of carbon dioxide of the non-intubation group was higher than that of the intubation group (P=0.012). The non-intubation group was superior to the intubation group in postoperative recovery and inflammatory response (P<0.05).ConclusionThe non-intubation anesthesia is safe and maneuverable in thoracic surgery, and it has some advantages in accelerating postoperative rehabilitation.
Objective To assess the efficacy of topical non-steroidal anti-inflammatory drugs （NSAIDs） in the treatment of osteoarthritis （OA）. Methods MEDLINE, EMBASE, Scientific Citation Index, CINAHL, The Cochrane Library, CBMdisc and abstracts from conference were searched from 1966 to March 30, 2005. Randomized controlled trials （R.CT） comparing topical non-steroidal anti-inflammatory drug （NSAIDs） with placebo or oral NSAIDs in OA were induded. Effect size （ES） was calculated for pain, function and stiffness. Relative risk （RR） was calculated for dichotomous data such as clinical response rate and adverse effect rate. Number needed to treat to obtain the clinical response was estimated. The quality of trials was assessed and sensitivity analyses were undertaken. Results Topical NSAIDs were superior to placebo in relieving pain due to osteoarthritis only in the first 2 weeks of treatment; ES （95% CI） were 0.41 （0. 16 to 0.66） and 0.40 （0.15 to 0.65） at week 1 and 2 respectively. However, the effects were short-lived and no benefit was observed over placebo at the third and fourth week. A similar pattern was observed with function, stiflhess and clinical response RR and number needed to treat. Topical NSAIDs were inferior to oral NSAIDs at week 1, and associated with more local side effects such as rash, itch or burning （RR 5.29, 95% CI 1.14 to 24. 51 ）. Conclusions Only very shortterm （less than 4 weeks） RCTs have assessed topical NSAID efficacy in OA ; after 2 weeks no efficacy above placebo has been obsevrved. There are no trial data to support the long-term use of topical NSAIDs in osteoarthritis.
Objective To analyze inducing factors and clinical characteristics of deep venous thrombosis (DVT) and to explore clinical value of soluble cell surface differentiation antigen 40 ligand (sCD40L) in early diagnosis of DVT. Methods The patients with the DVT of lower extremity who had not received the anticoagulant and thrombolytic therapy in the Nanchong Central Hospital from January 2012 to January 2017 were collected, these patients were divided into an early-acute stage, mid-acute stage, late-acute stage, and subacute stage according to the clinical course of DVT. The sCD40L expression in the peripheral blood of DVT patients were detected by the enzyme linked immunosorbent assay. Results There were 100 patients with the DVT were included, including 31 cases of early-acute stage, 26 cases of mid-acute stage, 21 cases of late-acute stage, and 22 cases of subacute stage; 66 patients with the peripheral type, 28 patients with the central type, and 6 patients with the mixed type. ① The fracture, malignant tumor, long time in the bed following the thoracic or abdominal operation, joint replacement, and caesarean section were the successively main risk factors of the DVT. ② The early-acute stage of DVT was more common in the fracture patients, the mid- and late-acute stage of DVT often occurred in the joint replacement sufferer, and the subacute stage of DVT was usually found in the malignant tumor patients. ③ The sCD40L expression in the patients with the different stage DVT was signifiantly higher than that in the control group (20 healthy people in the physical examination, P<0.05). Furthermore, there was a significant difference in the different stage DVT patients (F=26.57, P=0.02), that is, the expression of sCD40L was the highest in the early-acute stage of DVT, and then gradually reduced (P<0.05). ④ The sCD40L expression had a significant difference among the central type DVT, mixed type DVT, and peripheral type DVT (F=12.51, P=0.02), which in the peripheral type DVT was significantly higher than that of the central type DVT (P<0.05) and mixed type DVT (P<0.05), but had no difference between the central type DVT and the mixed type DVT (P>0.05). ConclusionsCD40L might act as a blood index of early diagnosis and judgement of extent of DVT, especially be helpful in early-acute stage of DVT.
Acute lung injury (ALI), in which various factors inside and outside the lung lead to hypoxemic respiratory insufficiency and even the development of acute respiratory distress syndrome, has a high morbidity and mortality rate, and its pathogenesis is characterized by complex signaling pathways and limited therapeutic options. A large number of studies have reported that nuclear factor kappa B (NF-κB), phosphatidylinositol 3-kinase (PI3K)/Akt, mitogen-activated protein kinase (MAPK), AMP-activated protein kinase (AMPK), vascular endothelial growth factors (VEGF) and JAK/signal transducer and activator of transcription (STAT) signaling pathways are all related to the inflammatory response of ALI, and they are involved in regulating the inflammatory response process of ALI individually or cooperatively. Therefore, this article reviews the research progress on the pathogenesis-related signaling pathways and the drug interventions, aiming to provide a reference for early intervention in lung injury, optimizing the donor pool to increase the proportion of donation after cardiac death and providing quality donor protection conditions.

Objectives To explore the expression of macrophage inflammatory protein-1beta (MIP-1β) in patients with none-small cell lung cancer (NSCLC) of different pathological types and its association with cancer clinical stages and metastasis of lymph nodes.Methods MIP-1β mRNA from fresh lung tissue of 38 NSCLC patients was amplified by RT-PCR and half-quantified.Immunohistochemical technique was performed to find out the expression of MIP-1β in paraffin-embedded lung tissue from 66 patients with NSCLC.The area and degree of stain were evaluated to determine the positive rate，which was compared between with or without metastasis of lymph nodes，different pathological types and TNM clinical stages.Results MIP-1β protein was found in cytoplasm of malignant cells of squama cell cancer and adenocarcinoma without significant difference between them，while not found in bronchus-alveolus cell cancer.The MIP-1β mRNA expression in squama cell cancer and adenocarcinoma were significant higher than which in bronchus-alveolus cell cancer without significant difference between each other.The positive rates of MIP-1β in lung cancer of Ⅰ，Ⅱ and Ⅲ stages were 74.2%，29.4% and 85.7% respectively，which of Ⅰ and Ⅲ stages cancer were significant higher than Ⅱ stage without significant difference between each other.The positive rates of MIP-1β in lung cancer with or without metastasis of lymph nodes were 45.8% and 76.3% respectively with significant difference between them.Conclusion MIP-1β is expressed in lung cancer cells and relates to the pathological type，TNM stage and the metastasis of lymph nodes.
ObjectiveTo investigate the effect of early postoperative systemic inflammatory response syndrome (SIRS) on the short-term outcome of patients with acute Stanford type A aortic dissection (ATAAD).MethodsThe clinical data of 88 patients with ATAAD who were treated in our hospital from January 2018 to January 2020 were retrospectively analyzed. Patients were divided into a SIRS group (n=37) and a non-SIRS group (n=51) according to whether SIRS occurred within 24 hours after surgery. The perioperative data of the two groups were compared.ResultsThere was no significant difference between the two groups in general clinical data, preoperative left ventricular ejection fraction, white blood cell (WBC) and body temperature (P>0.05). Compared with the non-SIRS group, the cardiopulmonary bypass time in the SIRS group was significantly longer (P<0.05), and the WBC and body temperature within 1 day after surgery in the SIRS group were higher (P<0.01). A significant difference was revealed in the mechanical ventilation time, ICU stay, total hospitalization time and hospitalization costs between two groups (P<0.01). Patients in the SIRS group had higher postoperative acute physiology and chronic health evaluationⅡscores, sequential organ failure assessment score as well as a greater risk of developing postoperative acute lung injury, acute kidney injury, continuous renal replacement therapy, delirium, liver dysfunction and morbidity (P<0.05).ConclusionEarly postoperative SIRS significantly increases the incidence of major adverse complications and the mortality rate of patients with ATAAD.
To evaluate the process from systemic inflammatory response syndrome (SIRS) to multiple organ dysfunction syndrome (MODS) and probe the therapeutic strategies for elderly patients, we retrospectively studied the clinical data of SIRS and MODS in 292 elderly patients with surgical abdominal emergency. Results: On admission, the morbidity rate of SIRS was 41.1%. Afterwards the morbidity rate of MODS was 14.2%, and the mortality rate of the elderly patients with SIRS was 11.7%. After 48 hours of therapy, MODS was developed in 40.5% of the cases also with SIRS. Of all the 292 elderly patients, 19 cases (6.5%) developed MODS and 16 patients (84.2%) died. Conclusion: The outcome of the patients with surgical abdominal emergency may be improved if SIRS is early diagnosed, the cause of SIRS after 48 hours therapy is well defined and the body inflammatory response is properly regulated.
ObjectiveTo investigate the protective effect and mechanism of arbutin on LPS induced Acute lung injury in mice. Methods SPF BCLB/C mice were randomly divided into control group, model group,arbutin group, and arbutin+PI3K inhibitor group.arbutin group and arbutin+PI3K group were intervened with corresponding drugs respectively; Constructing an ALI model by intranasal instillation of LPS into mice; After modeling for 6 hours, the mice were killed. After staining the lung tissue slices, observe the pathological changes of the lung tissue and evaluate the lung injury score, and calculate the wet to dry weight ratio (W/D); ELISA method was used to determine the levels of TNF-a and IL-6 in serum and bronchoalveolar lavage fluid (BALF); Measure the ROS content, MDA level,and MPO activity in the lungs; Western blot method was used to detect the expression of PI3K/Akt/mTOR pathway related proteins and autophagy related proteins Beclin-1 and LC3II/I. ResultsCompared with the control group, the pathological changes in the lung tissue of model group mice worsened, and the W/D and lung injury scores increased, The levels of IL-6 and TNF-a in BALF and serum was increased, The ROS content, MDA expression and MPO activity in the lungs was increased,the expression of Beclin-1 and LC3II/I in the lungs was increased. The expression of PI3K/Akt/mTOR pathway related proteins in the lungs decreased (P<0.05). Compared with the model group, the pathological changes in the lung tissue of arbutin group mice were alleviated, with a decrease in W/D and lung injury score, The levels of IL-6 and TNF-a in BALF and serum decrease,ROS content, MDA expression and MPO activity in lung were decreased.The expression of PI3K/Akt/mTOR pathway related proteins in the lung was increased, The expression of Beclin-1 and LC3II/I decreased. However, the appeal performance was partially blocked in the arbutin+PI3K group after the administration of LY294002.ConclusionsArbutin regulates autophagy through PI3K/Akt/mTOR pathway to inhibit inflammatory response and oxidative stress in LPS-induced ALI mice, and plays a protective role in LPS-induced ALI.
