Postoperative pain seriously affects the recovery process of patients, resulting in prolonged hospital stay and increased care costs. Appropriate application of patient-controlled analgesia devices can effectively relieve perioperative acute pain. In 1994 patient-controlled analgesia began to be used in Peking Union Medical College Hospital, and the Acute Pain Service Working Group was established in 2004. With the cooperation of anesthesiologists and specialist nurses, the group jointly has implemented the whole process and standardized management based on patient-controlled analgesia, and constantly improved and innovated working methods, laying a solid foundation for the development of postoperative pain management. This paper systematically reviews and summarizes the work from the aspects of clinical focus, nursing management experience, promotion and dissemination of pain treatment concepts, and development of acute pain service model under the new situation, with the hope of providing valuable reference for comprehensively strengthening pain management in the process of diagnosis and treatment, and enhancing patients' satisfaction with perioperative analgesia services.

Schizophrenia is a common chronic mental disorder.Cognitive dysfunction is one of its core symptoms,which severely affects the social functioning of patients.Currently,antipsychotic medication treatments have poor efficacy in improving cognitive functions.Recent studies have found that metformin can improve cognitive dysfunction in patients with schizophrenia.However,the mechanism of action remains unclear.This review summarizes the therapeutic effects of metformin on cognitive dysfunction in schizophrenia patients such as improving insulin resistance,repairing neuronal damage,regulating neuroimmunity,and combating oxidative stress,thereby providing new insights for the treatment of cognitive dysfunction in schizophrenia.

OBJECTIVE Vascular dementia(VaD)is associated with cerebral hypoperfusion,which results in long-term cognitive impairment and memory loss.Neuroin-flammation is an important mechanism of vascular demen-tia.Cornel iridoid glycoside(CIG)is the major active con-stituent isolated from the ripe fruit of Cornus officinalis.Previous studies have shown that CIG enhances neuro-logical function in VaD rats.In the present research,we attempted to clarify the molecular processes underlying the role of CIG on neuroinflammation in VaD.METHODS In vivo,we created a chronic cerebral ischemia rat model by ligation of the bilateral common carotid arteries(2VO).The rats were divided into sham operation,2VO,2VO + CIG(60 and120 mg·kg-1·d-1),and 2VO+ butylphthalide(100 mg·kg-1·d-1)groups and then treated rats with differ-ent concentrations of CIG.In vitro,BV2 microglia cells were induced with bacterial lipopolysaccharide(LPS)and interferon-γ(IFN-γ)to construct the model of microglias with analog neuroinflammation.Histopathology and biel-schowsky silver staining were used to detect myelin integrity and neuronal loss.Immunofluorescence was used to observe changes in microglia.Magnetic Luminex Assay was used to detect changes in inflammatory fac-tors.Western blotting,ELISA or calpain activity assay was used to measure the expression and activity of cal-pain,as well as the expression of NLRP3 inflammasome protein.Furthermore,NLRP3 overexpressing cells were used to further elucidate the potential anti-inflammatory molecular mechanism of CIG.RESULTS ① CIG improved neuronal impairment in the brain of 2VO rats.②CIG increased white matter(WM)integrity in 2VO rats.③ CIG reduced microglia inflammatory response in the cortex and hippocampus of 2VO rats.④ CIG inhibited calpain activity in the cortex and hippocampus of 2VO rats.⑤ CIG exerted anti-inflammatory effects on BV2 cells stimulated by LPS and IFN-γ.⑥ CIG Inhibited the expression and activity of calpain in LPS/IFN-γ-activated BV2 cells.⑦ The main component of CIG had a weak binding force to calpain1.⑧ CIG inhibited the activation of the NLRP3 inflammasome.⑨CIG reduced the activity of calpain induced by NLRP3 overexpression.CONCLU-SION CIG inhibits microglial polarization into a proinflam-matory state by attenuating the assembly of the NLRP3 inflammasome and calpain activation,thus reducing brain inflammation,WM injury,and the loss of neurons.To sum up,the present study suggests that CIG inhibits neuroinflammation.The NLRP3/calpain pathway may be the main pathway by which CIG protects against neuroin-flammation.

Multiple sclerosis(MS)is a systemic inflammatory illness of the central nervous system that involves demyelinating lesions in the myelin-rich white matter and pathology in the grey matter.Despite signifi-cant advancements in drug research for MS,the dis-ease's complex pathophysiology makes it difficult to treat the progressive forms of the disease.In this study,we identified a natural flavonoid compound icariin(ICA)as a potent effective agent for MS in ameliorating the deterioration of symptoms including the neurological defi-cit score and the body weight in a murine experimental autoimmune encephalomyelitis(EAE)model.These improvements were associated with decreased demyelin-ation in the corpus callosum and neuron loss in the hippo-campus and cortex confirmed by immunohistochemistry analysis.Meanwhile,it was observed that the activation of microglia in cerebral cortex and hippocampus were inhibited followed by the neuroinflammatory cytokines downregulation such as IL-1β,IL-6 and TNF-α after ICA treatment,which was probably attributable to the sup-pression of microglial NLRP3 inflammasome activation.Additionally,molecular docking also revealed the binding force of ICA to NLRP3 inflammasome protein complexes in vitro.Taken together,our findings have demonstrated that ICA,as pleiotropic agent,prevents EAE-induced MS by improving demyelination and neuron loss,which inter-feres with the neuroinflammation via microglial NLRP3 inflammasome activation.

ObjectiveTo investigate the regulatory effect and molecular mechanism of berberine （BBR） on lipophagy in the prevention and treatment of atherosclerotic （AS） lesions in mice. MethodFifty apolipoprotein E-knockout （ApoE^-/-） mice were randomly divided into an AS model group， an atorvastatin group （5 mg·kg^-1）， and low-， medium-， and high-dose BBR groups （2.5， 5， 10 mg·kg^-1）. Ten C57BL/6J mice were assigned to the control group. After 12 weeks， hematoxylin-eosin （HE） and oil red O staining were performed to assess the histopathological changes of AS plaques in the aorta. Biochemical analysis was used to measure serum lipid levels， and enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of inflammatory cytokines interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α）， oxidative stress marker reactive oxygen species （ROS）， and serum lipophagy marker Beclin1 and microtubule-associated protein 1 light chain 3 Ⅱ （LC3Ⅱ）. The xanthine oxidase method was used to measure serum superoxide dismutase （SOD） activity. Immunohistochemistry （IHC） was used to detect the distribution of wingless-type MMTV integration site family member 5a （Wnt5a） and Nieman Pick type C1 （NPC1） in the aorta， and Western blot was used to determine the protein expression of Wnt5a and NPC1 in the aorta. ResultCompared with the control group， the AS model group showed significant AS plaque formation， significantly elevated levels of serum total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， IL-6， TNF-α， and ROS， aortic Wnt5a distribution and protein expression （P<0.01）， and significantly reduced levels of serum high-density lipoprotein cholesterol （HDL-C）， SOD， Beclin1， LC3Ⅱ， and aortic NPC1 distribution and protein expression （P<0.01）. Compared with the AS model group， the atorvastatin group， and high- and medium-dose BBR groups showed a significant reduction in AS plaque area （P<0.05， P<0.01）， significantly decreased levels of serum TC， TG， LDL-C， IL-6， TNF-α， ROS， and aortic Wnt5a distribution and protein expression （P<0.05， P<0.01）， and significantly increased levels of serum HDL-C， SOD， Beclin1， LC3Ⅱ， and aortic NPC1 distribution and protein expression （P<0.05， P<0.01）. There was no statistically significant difference in the above indicators between the atorvastatin group and the medium-dose BBR group. ConclusionBBR can competitively bind to Wnt5a to activate NPC1 expression， upregulate lipophagy levels， reduce blood lipids， and inhibit the release of inflammatory mediators and oxidative stress damage， thereby exerting a preventive and therapeutic effect on AS.

Objective To explore the effects of family involvement and online extended nursing for postoperative rehabilitation in patients with cervical spinal cord injury (CSCI). Methods Totally 60 CSCI patients who were admitted and received surgery in Honghui Hospital, Xi'an Jiaotong University from October 2013 to July 2016 and their major caregivers after being discharged from hospital were equally divided into an observation group (n=30) and a control group (n=30) according to the random number table. Patients in the control group received conventional instructions 1 day before being discharged from hospital and telephone follow-ups in Week 1, Month 1, Month 3 and Month 6 after being discharged from hospital, while patients in the observation group received extended nursing via WeChat groups on this basis. The quality of life, incidence of complications and compliance of rehabilitation exercise six months after surgery were compared between the patients in the two groups. Results The patients in the two groups showed higher scores in various dimensions indicating the quality of life six months after surgery than they did at discharge, and the patients in the observation group showed higher scores than the patients in the control group (P< 0.05). The patients in the observation group showed lower incidence of abdominal distension, constipation and pressure ulcer complications than the patients in the control group (P<0.05), and the incidence of high fever, pulmonary infection and urinary tract infection tended to decline (P>0.05). The patients in the observation group showed higher compliance of rehabilitation exercise than the patients in the control group (P< 0.05). Conclusions Family involvement and WeChat extended nursing helps to build a long-term service system for CSCI patients and accelerate their postoperative rehabilitation, thus worthy of expansion and application.

Objective To explore the effects of sound operation on nursing quality in nursing work at spine surgery.Methods Totally 531 cases of patients at spine surgery in our hospital from July 2015 to October 2015 were randomly divided into the control group ( n=264) and the intervention group ( n=267) . Patients in two groups were given routine nursing, and patients in the intervention group also were given sound operation. The incidence of nursing adverse events, the writing quality of nursing documents, the situation of health education, the rate of patient complaints and the satisfaction degree toward nursing were collected and analyzed. Results Nursing adverse events in the intervention group was 1 case ( 0. 4%) which were less than 11 cases (4.2%) in the control group (P<0.05). There were 2 cases (0.7%) of nonstandard nursing documents and 3 cases (1.1%) of lipography in nursing documents in the intervention group, which were less than 11 cases (4.2%) and 16 cases (6.1%) in the control group (P<0.05). There was no case of patient complaints in the intervention group which were less than 4 cases (1.5%) in the control group (P<0.05). The situation of health education in the intervention group was 1 case (0.4%) which was less than 8 cases (3.0%) in the control group (P<0.05). The satisfaction degree toward nursing in the intervention group was 97.75%(261/267)and was 92.80%(245/264) in the control group ( P<0. 05). Conclusions Sound operation in nursing work can effectively reduce nursing adverse events at spine surgery, and it also can improve the quality of nursing.

Considerable attention has been directed toward studying the impact of diabetes on the central nervous system. The current study investigates the biochemical changes in the brain tissue of streptozotocin (STZ)-induced diabetic rat using 31P magnetic resonance spectroscopy (31P MRS). The 31P NMR spectra of the whole brain show no significant changes of phosphomonoesters and phosphodiesters levels one week after STZ induction, suggesting no apparent structural changes in cell membranes. The results identifies the increased level of adenosine diphosphate, negligible changes of phosphocreatine ( PCr ) and adenosine triphosphate ( ATP) , but the decreased ratio of PCr/ATP, indicating that PCr plays a role of balancing the energy. Moreover, the decreased pH value indicates the changes of the intracellular environment in STZ-diabetic brains in rats. After 15 weeks of STZ injection, the metabolism of phospholipid membrane and brain energy metabolism has been obviously disturbed. Our study successfully shows that 31 P MRS can not only study phospholipid and energy metabolism non-invasively, but also measure intracellular pH and other important biochemical information. All of these spectroscopic characterizations contribute significantly to the understanding of pathogenesis and evolution of diabetes, and provide theoretical basis for early diagnosis and clinical treatment in diabetes.
