ABSTRACT
OBJECTIVE The preference for social novelty is crucial to the social life of humans and rodents.However,the neural mechanisms underlying social novelty preference are poorly understood.Dorsal hippocampal CA3(dCA3)is an important brain area that responds to social defeat stress,and the neural circuitry of dCA3→lat-eral septum(LS)participates in the context-associated memory.Meanwhile,the parvafox nucleus(PFN)Foxb1+ neurons regulate the defensive reaction to life-threaten-ing situations.Therefore,we investigate a cell-specific cir-cuit of dCA3CaMKⅡα+→dorsal LSGABA+→PFNFoxb1+ in social novelty preference.METHODS Chronic social defeat stress(CSDS)and three-chamber social interaction test were performed in adult male C57BL/6J mice to detect social behaviors.Optogenetic and chemical-genetic experiments were conducted to regulate the circuit.RESULTS CSDS reduced the preference for social nov-elty in mice and the response of dCA3CaMKⅡα+ neurons dur-ing approach to an unfamiliar mouse was impaired by CSDS.Optogenetic inhibition of dCA3CaMKⅡα+→dLS pro-jection reduced the preference for the unfamiliar mouse versus a familiar mouse.Meanwhile,optogenetic activa-tion of dCA3CaMKⅡα+→dLS projection rescued the prefer-ence for social novelty of CSDS-treated mice.Manipula-tions dLSGABA+→PFN projection activation regulated the preference for social novelty in mice.Optogenetic activa-tion of PFNFoxb1+→lPAG projection reduced the prefer-ence for a familiar C57BL/6J mouse versus a novel object in control mice.CSDS decreased the excitability of dCA3CaMKⅡα+ neurons by up-regulation of Kir2.4(Kcnj14)expression.CONCLUSION Our present study suggest-ed that activation of a cell-specific circuit of dCA3CaMKⅡα+→dLSGABA+→PFNFoxb1+→lPAG reverses the deficits of social novelty preference in defeated mice,and inhibition of this circuit reduces the preference for social novelty.The cir-cuit that regulates the preference for social novelty deficits may provide a new information for the potential therapeu-tic targets for neuropsychiatric diseases.
ABSTRACT
Objective:To analyze the survival rate of malignant tumor in the elderly over 60 years old in Qidong city from 1972 to 2016, and to provide basis for prognosis evaluation and prevention.Methods:Based on the data of 66 386 patients with malignant tumor in the elderly over 60 years old in the Qidong cancer registration and reporting system, the survival outcome was tracked by the method of active follow-up and passive follow-up.All of these data were then analyzed by stratification of sex, age, tumor site and hospital level.Results:During the period of 1972 to 2016, the total number of patients with malignant tumors in the elderly were 66 386 cases, accounting for 56.66% of patients in all age groups.The observed survival rate(OSR)of 5 and 10 years were 14.52% and 9.53% and relative survival rate(RSR)of 5 and 10 years were 19.76% and 18.92%, respectively, in the elderly in Qidong.The 5-year RSR was 16.98% for males and 23.91% for females, being a statistically significant( χ2=339.83, P<0.001). The 5-year RSRs of elderly patients in males and females increased from 7.53% and 15.83% in 1972-1976 to 28.06% and 39.01% in 2012-2016, respectively.The 5-year RSR of 60-64, 65-69, 70-74, 75-79, 80-84 and 85 years old and over were 22.84%, 20.53%, 17.74%, 18.30%, 18.02% and 14.06%, respectively, with a statistically significant difference( χ2=694.27, P<0.001). Among the top 10 major malignancies, the ranks of 5-year RSR from high to low were breast cancer, prostate cancer, bladder cancer, colorectal cancer, malignant lymphoma, gastric cancer, liver cancer, esophageal cancer, lung cancer, and pancreatic cancer, respectively.A comparison between 2002--2016 and 1972--1986 showed that the increased rank of absolute values of RSR from highest to lowest were prostate cancer, colorectal cancer, female breast cancer, bladder cancer, gastric cancer, malignant lymphoma, liver cancer, esophageal cancer, lung cancer, and pancreatic cancer, respectively.The 5-year RSR of patients diagnosed in the district / township hospitals, county hospitals, city-level 3A hospitals and provincial-level 3A hospitals were 13.97%, 23.71%, 26.12% and 28.55%, respectively, with a statistically significant difference( χ2=841.93, P<0.001). In the 45 years, the average annual percentage change(AAPC)ratio of 5-year OSR was 3.88%( t=6.75, P<0.001), and the 5-year RSR was 3.69%( t=7.44, P=0.001); the AAPC of the 5-year RSR was 3.91%( t=9.66, P<0.001)in males and 3.42%( t=6.08, P=0.001)in females.The AAPC ratio of 5-year RSR in each age group were 4.08% for 60-64 years, 4.18% for 65-69 years, 3.91% for 70-74 years, 3.12% for 75-79 years, 3.81% for 80-84 years, 0.51% for 85 years old and over, respectively.Except for age group of 85 years old and over( P=0.615), significant rising trends were observed in all age groups( P<0.01). Conclusions:Malignant tumors in the elderly have become the major cancer burden in Qidong, and there are significant gender and age differences.The overall survival rate in elderly patients with malignant tumors has been significantly improved in the past 45 years, which may be related to the improvement in the level of diagnosis and treatment and the service capacity of hospitals.
ABSTRACT
Objective:To analyze the survival of pancreatic cancer cases in Qidong County, Jiangsu Province from 1972 to 2016, and provide a basis for the prognosis evaluation and prevention of pancreatic cancer.Methods:Data from a total of 4 341 registered pancreatic cancer patients in Tumor Registry of Qidong from January 1972 to December 2016 were selected, and all the patients were followed up until December 31, 2021. 1-, 3- and 5-year observed survival rate (OSR) and relative survival rate (RSR) were calculated and tested by Hakulinen likelihood ratio test method using SURV (3.01) software. Age-standardized relative survival rate (ARSR) was calculated according to the International Cancer Survival Standard (ICSS). Joinpoint (4.7.0.0) software was used to conduct the annual percentage change (APC) of pancreas cancer survival rate.Results:1-, 3- and 5-year OSR of pancreatic cancer were 13.82%, 5.87% and 4.70%, and 1-, 3- and 5-year RSR were 14.50%, 6.80% and 6.02%, respectively. 1-, 3- and 5-year RSR increased from 11.76%, 4.84% and 3.29% in 1972—1976 to 18.80%, 7.39% and 6.49% in 2012—2016. The uptrends of RSR were statistically significant (χ 2=59.84, P<0.001). 1-, 3- and 5-year RSR for male were 14.31%, 6.40% and 5.82%, and 1-, 3- and 5-year RSR for female were 14.74%, 7.28% and 6.26%, respectively. There was no statistically significant difference on RSR between male and female (χ 2=6.68, P=0.463). The 5-year RSR for the age group of 45-54, 55-64, 65-74, and ≥75 years old were 8.14%, 6.74%, 4.69% and 5.24%, respectively, and the survival rate was decreased with age. There was a statistically significant difference on RSR among different age groups (χ 2=19.52, P=0.012). 1-, 3- and 5-year ARSR of pancreas cancer were 14.67%, 6.84% and 6.04%. For male, 1-, 3- and 5-year ARSR were 14.36%, 6.42% and 5.79%, and for female were 15.25%, 7.55% and 6.47%, respectively. Period trend analysis showed that the APC of 1-, 3- and 5-year ARSR was 0.91% ( t=1.94, P=0.094), -0.22% ( t=-0.30, P=0.774) and -0.77% ( t=-0.95, P=0.374) from 1972 to 2016 in Qidong. The APC of 5-year ARSR in male and female were -1.50% ( t=-1.31, P=0.232) and 1.11% ( t=0.37, P=0.722); there were no statistically significant increase or decrease for both male and female among ARSR in nine periods (5 years as a period). The APC of 5-year RSR among 45-54, 55-64, 65-74 and ≥75 years old were 2.46% ( t=0.57, P=0.588), 3.16% ( t=0.87, P=0.413), 0.95% ( t=0.26, P=0.805) and -2.56% ( t=-2.61, P=0.035), respectively. Except for ≥75 years old age group who had a statistically significant downward trend, there were no statistically significant upward trend in the other age groups. Conclusions:The overall survival rate of pancreatic cancer in Qidong from 1972 to 2016 has been at a low level, and it is necessary to introduce a standardized multi-disciplinary treatment mode to improve treatment efficacy and survival rate.
ABSTRACT
Objective To study and analyze the trend of diabetes death and the impact of life expectancy in Qidong City, Jiangsu Province from 1990 to 2019, and to provide a basis for formulating health policies. Methods Based on the surveillance data of deaths from all causes in Qidong City and the population data over the years from 1990 to 2019, the residents' diabetes mortality and temporal trends were analyzed. Joinpoint4.7.0.0 software was used to calculate relevant indicators including crude mortality (CR), age-standardized rates by China population (CASR), annual percentage change (APC), potential years of life lost (PYLL), and potential years of life lost rate (PYLLR). Results The CR of diabetes in Qidong City from 1990 to 2019 was 15.12/100 000, with a rate of 12.72/100 000 in males and a rate of 17.45/100 000 in females. The total CASR was 7.58/100 000, including 6.47/100 000 for males and 8.59/100 000 for females. Trend analysis showed that the APC of CR and CASR was 9.31% and 5.26% in males, and 8.12% and 4.40% in females, respectively. The APC of CR and CASR in the 45-64 years old group was 2.59% and 4.85%, respectively. The APC of CR and CASR in the 65 years old and above group was 7.20% and 9.79%, respectively. There were statistically significant differences except for the 15-44 years old group. The life expectancy of residents in Qidong City rose from 73.95 years in 1990 to 82.91 years in 2019 (APC=0.38, P<0.001), and life expectancy without diabetes rose from 74.01 years in 1990 to 83.39 years in 2019 (APC=0.39, P<0.001). Conclusion In the past 30 years, the diabetes mortality and life loss of residents in Qidong City have been increasing year by year and the trend is obvious. Women's diabetes mortality and life loss are higher than those in men. The level and increase rate of diabetes mortality in the high age group are higher than those in the low age group. It is necessary to carry out key intervention for the corresponding population.

ABSTRACT
BACKGROUND: Wound complications probably result in severe soft tissue defects after total knee arthroplasty, which brings orthopedic surgeon a big challenge. Some treatment options, such as frequent sterile dressings changes, persistent drainage, minor or thorough debridement, negative pressure wound therapy and split-thickness skin grafts, fail to help those quite large and deep wounds around the knee, with exposed fascia or prosthesis, bone, joint, tendon, large vessels and nerve, heal by secondary intention. Under these situations, orthopedic surgeon should consult plastic surgery and propose flap re-construction. OBJECTIVE: To introduce some types of flaps for orthopedic surgeon, so as to help orthopedic surgeon understand and chose flaps logically, and reduce severe consequences caused by soft tissue defect wounds. METHODS: The first author retrieved databases of PubMed, Medline, Wanfang and CNKI for the articles concerning wounds repaired by flap transfer after total knee arthroplasty published before 2019. The key words were "flap, knee, wound" in Chinese and English, respectively. Initially 668 articles were retrieved and 45 eligible articles were included in accordance with the inclusion and exclusion criteria for analysis. RESULTS AND CONCLUSION: (1) Flap reconstruction is widely applied in plastic surgery. It is significant for orthopedic surgeon to recognize the characteristics of each flap. (2) Selecting and designing suitable type of flap according to the three-dimensional structure and position of wounds is helpful for repairing soft tissue defect, reducing the risks of prosthesis exposure, periprosthetic infection, prosthesis removal and even amputation after total knee replacement after total knee arthroplasty.
ABSTRACT
Objective:To investigate the long-term survival rate and the influencing factors for prognosis in patients aged 80 years and over who underwent hemodialysis.Methods:Clinical data of 82 patients with end stage renal disease (ESRD) who started dialysis in≥80 years of age and underwent hemodialysis for more than three months in our hospital from May 2008 to May 2017 were retrospectively analyzed.Kaplan-Meier method was used to analyze the survival rate of patients.Log-rank test was used to compare survival rate of hemodialysis patients aged≥80 years versus aged<80 years.Cox regression model was performed to analyze the influencing factors for prognosis in elderly patients undergoing hemodialysis.Results:The median survival time of 82 hemodialysis patients aged≥80 years was 34 months, and their 6-month, 12-month, 24-month and 36-month survival rates were 90.0%, 73.6%, 60.8% and 49.4%, respectively.The top three death causes were cardiovascular events, septic shock, and malignant tumors.The median survival time of the hemodialysis patients aged<80 years was 52 months, and their 6-month, 12-month, 24-month and 36-month survival rates were 94.7%, 85.5%, 72.4% and 65.8%, respectively.Log-rank test demonstrated that the survival rate was lower in patients aged≥80 years than in patients aged<80 years( χ2=5.284, P=0.022). Multivariate Cox regression analysis indicated that diabetes mellitus was an independent risk factor for the survival in hemodialysis patients aged≥80 years( HR=3.470, 95% CI: 1.364~8.827, P=0.009), while targeted levels of body mass index(BMI)( HR=0.806, 95% CI: 0.706~0.921, P=0.001)and serum albumin level( HR=0.861, 95% CI: 0.789~0.938, P=0.001)were the independent protective factors for the survival in hemodialysis patients aged≥80 years. Conclusions:The survival rate is lower in hemodialysis patients aged≥80 years than in those aged<80 years.The top death causes is cardiovascular events, septic shock, and malignant tumors.Diabetes mellitus, low levels of BMI and serum albumin are the main risk factors for the survival in advanced elderly patients undergoing hemodialysis.

ABSTRACT
OBJECTIVE: To understand the current status and influencing factors of job burnout in rural preschool teachers. METHODS: A stratified cluster random sampling method was used to investigate the job burnout and social support of 756 rural preschool teachers in Sichuan Province using the Maslach Burnout Inventory, Educators Survey and Social Support Revalued Scale. RESULTS: The positive rate of job burnout was 22.1%(167/756), and the positive rates of emotional exhaustion, reduced personal achievement, and depersonalization were 13.1%, 10.7% and 1.2%, respectively. The results of unconditional logistic regression analysis showed that post status, daily working hours, subjective support and utilization of support were all related to job burnout(P<0.05). Among them, in-post and daily working hours >10 hours were risk factors of job burnout, high subjective support and utilization of support were the protective factors of job burnout. CONCLUSION: The situation of job burnout in rural preschool teachers in Sichuan Province is not serious, post status, daily work hours and social support can affect their job burnout.
ABSTRACT
Objective:To determine the prevalence, disease burden, and possible causes of lung cancer. Population-based lung cancer registration data collected from 1993 to 2012 were used to analyze the lung cancer epidemic status in Qidong City. Methods:Joinpoint regression was used to calculate the trend of incidence and mortality for lung cancer. Age-period-cohort model was used to assess the effects of age and exposure on the incidence and mortality rates. Results:Upward trends were observed both for the incidence and mortality rates of lung cancer. The risk of incidence and mortality increased with age. According to the cohort effect, the risk of lung cancer increased with recent birth dates. Women had higher risk than men. Conclusion:The incidence and mortality rates of pulmo-nary neoplasms have annually increased, and the exposure to risk factors for lung cancer gradually increases. Among the community population in Qidong City, people over 70 years belong to the high-risk groups.
ABSTRACT

METHODS Samples of 120 cases of laryngocarcinoma were collected from the Otolaryngology Department of the First Affiliated Hospital of Jinzhou Medical University from 2013 to 2015. Patients were divided into two groups: metastasis group and non-metastasis group. Immunohistochemistry was performed to analyze the NMU expression in primary tumor and lymph node. An independent tissue microassay was used to analyze the relationship between NMU expression and T, N stages. RESULTS Expression of NMU in metastasis group was higher than that in non-metastasis group, NMU was positively correlated with N stages, but not with T stages. CONCLUSION The expression of NMU is higher in metastasis tissue of laryngocarcinoma, It could be used as a biomarker of lymph node metastasis of laryngocarcinoma.
ABSTRACT
Objective@#To evaluate the patients′ survival and effectiveness of the live cancer screening for population at high risk for liver cancer in Qidong.@*Methods@#According to the Expert Scheme proposed the Expert Committee of Early Detection and Early Treatment, China Cancer Foundation, diagnostical screening by using combined methods of alpha-fetoprotein and B ultrasound monitoring were carried out biannually in individuals with positive HBsAg who were screened from Qidong area. The evaluation indices of the effectiveness are task completion rate of screening, detection rate of liver cancer, early diagnosis rate, and treatment rate. The deadline of the follow-up for the surviving outcome was March 31, 2016. The life-table method was used to calculate the observed survival, and to make comparison and significant tests between survival rates in Group A (those found via repeated periodic screening) and Group B (those diagnosed without periodic screening).@*Results@#Since 2007, 38 016 target population have been screened, and 3 703(9.74%) individuals with positive HBsAg were found. Except for 29 patients with liver cancer at the initial screening, 3 674 persons in the cohort were followed up; 268 patients with liver cancer were detected from the 33 199 person-times screening, with an annual detection rate of 1.61%. Of them, 186 patients were found in Group A(1.12%), in which 149 patients were the early cases, with an early detection rate of 80.11%; 167 out of 186(89.78%) patients received treatment after diagnosis. The incidence of liver cancer in this HBsAg (+ ) cohort of 25 452 person-years was 1 052.96 per 100 000 annually, 187 cases in males(1 488.45/100 000)and 81 cases in females(628.46/100 000). The 1-, 3-, 5-, and 8-year survival of all patients with liver cancer were 64.55%, 40.50%, 32.54%, and 19.65%, respectively. The 1-, 3-, 5-, and 8-year survival rates were 77.16%, 49.04%, 38.53%, and 24.25% in Group A, and were 36.25%, 21.21%, 21.21%, and 0% in Group B, respectively, with significant differences between two groups (P<0.05).@*Conclusion@#The findings show that screening of individuals at high-risk of development of liver cancer, with semiannual AFP and B ultrasound, according to the Expert Scheme, is effective not only in increasing detection rate but also in detecting liver cancer at early stage, and in improving patients′ survival as well.
ABSTRACT
Objective This study aimed to investigate the role of pyrroloquinoline quinone (PQQ) in repairing oxidative nerve cells,and to study the antioxidant capacity of PQQ on the oxidative damage of rats caused by apolexis,as well as the effects on learning and memory abilities of apolexis rats.Methods Oxidative damage of PC12 was induced by H2O2,and the repairing rate of PQQ on oxidative PC12 cells was tested by methylthiazolyldiphenyl-tetrazolium bromide assay kit.The 18-month-old male SD rats were administered PQQ (0,10,20,40 mg/kg).After 4 weeks,Morris water maze test was used to test the learning and memory ability.After 6 weeks,serum and brain tissue related indicators and antioxidant capacity were recorded.Results The survival rate of PC12 cells increased from 59.1％ to 90.5％ with 200 nmol/L PQQ.Compared with the apolexis model group,the latency of the PQQ group (20,40 mg/kg) was shortened in the Morris water maze experiment,the swimming distance was reduced,pass-through counts were increased,and the first secure platform pass-through was reduced.Meanwhile,the levels of malondialdehyde and lipofuscin in serum and brain tissue of PQQ group decreased,the levels of superoxide dismutase,glutathione peroxidase vitality,antioxidant capacity of PQQ group (20,40 mg/kg) were enhanced.Conclusion PQQ could repair the oxidative damage of nerve cells,and it was confirmed that PQQ could play the same antioxidant effect in body and brain,and increase the learning and memory ability of apolexis rats.
ABSTRACT
Background and purpose:There are few studies referring to population-based cancer survival of bladder cancer for more than forty years in China. This paper was to offer basis for assessing long-term survival trends of bladder cancer and the prognosis of this cancer through analysis of the survival rates based on cancer report documents from 1972 to 2011 in Qidong.Methods:The deadline of the last follow-up for survival status of the 1 619 registered cases was Apr. 2012. Cumulative observed survival rate (OS) and relative survival rate (RS) were calculated using Hakulinen’s method performed by the SURV3.01 Software which is developed by Finnish Cancer Registry.Results:The one-, three-, five-, ten-, fifteen-, twenty-, and thirty-year OS rates were 59.91%, 43.49%, 35.98%, 26.91%, 21.30%, 18.37% and 12.24%; and the one-, three-, five-, ten-, fifteen-, twenty-, and thirty-year RS rates were 64.07%, 53.02%, 50.06%, 52.42%, 59.59%, 76.39% and 115.75%, respectively. For males, these OS rates were 60.84%, 43.91%, 36.95%, 27.31%, 21.49%, 18.29% and 12.59%, and RS rates were 65.23%, 53.95%, 52.02%, 54.57%, 62.59%, 79.12% and 117.07%, respectively; For females, these OS rates were 56.61%, 42.03%, 32.44%, 25.65%, 20.78%, 18.80% and 0%, and RS rates, 59.99%, 49.91%, 43.37%, 45.86%, 51.21%, 69.02% and 0%, respectively. There were no statistical differences couldbe found between both sexes (P=0.256). Five-year RS rates of age groups 15-34, 35-44, 45-54, 55-64, 65-74, and more than 75 were 49.10%, 67.53%, 62.77%, 53.92%, 46.59% and 39.85%, and 10-year RS rates, 49.79%, 61.23%, 52.99%, 48.21%, 54.94% and 51.21%, respectively. Remarkable improvement could be seen for the five-, ten-, and fifteen-year RS rates in this setting since 1980’s.Conclusion:The survival outcome from Qidong registered cases with bladder cancer shows gradual progress during the past 2 decades. Early detection and improvement of therapies may be the factors affecting the prognosis of bladder cancer. Although the disparities in survival rates between Qidong and the developed countries are getting narrower, potential for survival improvement still exists.

ABSTRACT
Objective To analyze the survival rates of patients with non-Hodgkin lymphoma (NHL) in Qidong from 1972 to 2011,in order to provide the basis for the prognosis assessment and the control of this cancer.Methods A total of 1 472 registered NHL cases were followed up to April 30, 2012.Cumulative observed survival (OS) rate and relative survival (RS) rate were calculated using Hakulinen method performed by the SURV 3.01 software developed at the Finnish Cancer Registry.Results The 1-, 3-, 5-, 10-, 20-and 30-year OS rates were 32.48 ％, 19.30 ％, 15.78 ％, 12.76 ％, 9.54 ％ and 7.63 ％, and the RS rates were 33.49 ％, 21.18 ％, 18.46 ％, 17.79 ％, 19.37 ％ and 22.44 ％, respectively.The 1-, 3-, 5-, 10-, 20-and 30-year RS rates of males vs females had no statistically significant differences (x2 =3.32, P =0.767).The 5-year RS rates of age groups 0-14, 15-34, 35-44, 45-54, 55-64, 65-74, and ≥75 were 22.99 ％, 20.51％,18.42 ％, 20.96 ％, 18.72 ％, 17.32 ％, 10.60 ％, and the 10-year RS rates were 23.04 ％, 15.55 ％, 15.91％,16.36 ％, 18.59 ％, 19.70 ％, 20.93 ％, respectively.The age group 0-14 had the highest 5-and 10-year RS rates.Remarkable improvement could be seen in the 5-year RS rate from 7.76 ％ in 1973-1977 to 26.79 ％ in 2003-2007, and the 10-year OS rate from 6.63 ％ in 1973-1977 to 15.52 ％ in 1998-2002, respectively.Conclusions The outcome of NHL in Qidong has been improved gradually from 1972 to 2011, but the gaps of survival rates in NHL patients between China and the developed countries still exist.Research on the diagnosis and treatment of NHL should be further emphasized.
ABSTRACT
OBJECTIVE:To evaluate therapeutic efficacy of Xuebijing injection in the treatment of severe craniocerebral trau-ma. METHODS:67 patients with severe craniocerebral trauma selected from neurosurgery department of our hospital were Treat-ment method divided into treatment group(33 cases)and control group(34 cases). Observation group was given conventional treat-ment,i.g. oxygen inhalation,dehydration,nourish cranial nerve,anti-infection. Treatment group On the basis of the control group was given Xuebijing injection 50 ml/time,tid,ivgtt. PT,TT,PLT,FIB,CK,LA, D-D,blood gas index (PaCO2,PaO2, HCO3-)of 2 groups were observed after 7 days of treatment,and prognosis of 2 groups were evaluated after 6 months as well as therapettin efficacy. RESULTS:After treatment,PT,TT,PLT,FIB,CK,LA, D-D,PaCO2,PaO2 and HCO3- of 2 groups were all better than before,and the treatment group was better than the control group,with statistical significance (P<0.05). The rate of good prognosis in treatment group (78.79%) was significantly better than in control group (55.88%) after 6 months of treat-ment,with statistical significance(P<0.05). CONCLUSIONS:Xuebijing injection in the treatment of severe craniocerebral trau-ma can improve coagulation function,blood gas levels and the inflammatory reaction,and is conducive to improve the patient's prognosis.
ABSTRACT
Glutamate acting on AMPA-type ionotropic glutamate receptor (AMPAR) mediates the majority of fast excitatory synaptic transmission in the mammalian central nervous system. Dynamic regulation of AMPAR by post-translational modifications is one of the key elements that allow the nervous system to adapt to environment stimulations. S-palmitoylation, an important lipid modification by post-translational addition of a long-chain fatty acid to a cysteine residue, regulates AMPA receptor trafficking, which dynamically affects multiple fundamental brain functions, such as learning and memory. In vivo, S-palmitoylation is controlled by palmitoyl acyl transferases and palmitoyl thioesterases. In this review, we highlight advances in the mechanisms for dynamic AMPA receptors palmitoylation, and discuss how palmitoylation affects AMPA receptors function at synapses in recent years. Pharmacological regulation of S-palmitoylation may serve as a novel therapeutic strategy for neurobiological diseases.
