RESUMEN
The complement system comprises intrinsic complement components,complement regulatory pro-teins,and complement receptors.Complement activation plays a role in promoting the sensitization of peripheral pain re-ceptors,enhancing immune cell activity,and participating in the regulation of axon regeneration after nerve injury.The in-teraction of the complement system contributes to the development and maintenance of pathological pain,affecting the dor-sal root ganglion neurons,spinal dorsal horn,and brain.Consequently,targeting the complement system holds promise as a therapeutic approach for neuropathic pain treatment.This paper reviews the progress in understanding the functions of the complement system and its implications in pathological pain,offering valuable insights for the future development of targeted drug therapies.
RESUMEN
OBJECTIVE@#To investigate the clinical efficacy of acrylic cement (PMMA) mixed with calcium sulfate combined with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic fracture (OVCF).@*METHODS@#The clinical data of 191 patients with OVCF treated with PKP from January 2020 to March 2021 were retrospectively analyzed. Among them, 82 patients with 94 vertebral bodies were treated with PMMA mixed with calcium sulfate as the observation group, and 109 patients with 125 vertebral bodies were treated with pure PMMA as the control group. Among the 82 patients in the observation group, there were 16 males and 66 females, with a mean age of (75.35±11.22) years old, including 36 thoracic vertebrae and 58 lumbar vertebrae. In the control group, there were 109 patients, 22 males and 87 females, with an average age of (74.51±9.21) years old, including 63 thoracic vertebrae and 62 lumbar vertebrae. The visual analog scale (VAS) before operation and 1 day, 3 months and 1 year after operation were calculated. The Oswestry disability index (ODI), Cobb's angle, vertebral body height and the probability of postoperative bone cement leakage were used to analyze the efficacy of the two groups.@*RESULTS@#All the patients were followed up for more than one year. Compared with the control group, there was no significant difference in operation time, bleeding volume and bone cement injection volume between the two groups(P>0.05), while the leakage rate of bone cement was significantly lower in the observation group (P<0.05). In addition, there was no significant difference in VAS, ODI, Cobb angle, and vertebral body height between the two groups before operation, and 1 day, 3 months, and 1 year after operation (P>0.05), but each index was improved compared with that before operation (P<0.05).@*CONCLUSION@#PMMA mixed with calcium sulfate has equivalent efficacy in treating OVCF than PMMA alone, but can effectively reduce the probability of cement leakage.

Cholestatic liver disease is a common disease that causes bile flow dysfunction due to various reasons. The etiology of cholestatic liver disease is complexed, and therapeutic drugs are extremely limited. To date, ursodeoxycholic acid is the only FDA-approved drug for treating primary biliary cirrhosis, whereas its efficacy is limited to early stage of the disease, therefore novel drugs are urgently needed. Nuclear receptors become therapeutic hotspot target in cholestasis since these receptors play a key role in regulating bile acid homeostasis. Peroxisome proliferator-activated receptor (PPAR) is an important nuclear receptor involved in regulating multiple mechanisms of cholestasis in vivo. It can improve intrahepatic cholestasis by inhibiting bile acid synthesis, reducing bile acid toxicity, affecting the expression of bile acid metabolic enzymes and transporters, and can play an anti-inflammatory, anti-oxidation and anti-fibrosis role. A number of studies have shown that PPAR agonists represented by fibrates alone or in combination can improve liver function indexes, inflammatory factors and fibrosis markers in patients with cholestasis. This review analyzes and summarizes the lastest advances in the molecular mechanism of PPAR as a therapeutic target for cholestasis and drug treatment in development or have been used in clinical.
RESUMEN
Objective:To analyze the influencing factors of the disease cognition level in main caregivers of children with congenital heart disease (CHD).Methods:In this prospective study, the main caregivers of 150 children with CHD admitted to the Seventh People′s Hospital of Zhengzhou from January 2018 to January 2020 were selected as the research objects with convenient sampling method, and a self-designed questionnaire on awareness of CHD disease was used for face-to-face investigation. A total of 150 questionnaires were issued, and 150 valid questionnaires were reclaimed. According to the total score of the questionnaire (>45 or ≤45), the subjects were divided into high score group (90 cases) and low score group (60 cases). The general data of the main caregivers of children with CHD in the two groups were collected, the χ2 test and logistic regression were used to analyze the influencing factors of disease cognition level in those caregivers. Results:The disease cognition score of the main caregivers of children with CHD in the two groups was (58.69±7.33). The proportions of people with high school education or above, living in cities and towns and obtaining disease knowledge from hospitals in the high score group were all significantly higher than those in the low score group (66.7% vs 36.7%, 72.2% vs 55.0%, 92.2% vs 78.3%) (all P<0.05). Low education level (primary school, OR=1.394, 95% CI: 1.131-1.657; junior high school/technical secondary school, OR=1.406, 95% CI: 1.052-1.761), living in rural area ( OR=1.343, 95% CI: 1.214-1.472), obtaining disease knowledge from outside the hospital ( OR=1.328, 95% CI: 1.037-1.620) were all positively related to the decline of disease cognition scores of the main caregivers of CHD children (all P<0.05). Conclusion:The main caregivers of children with CHD have a moderate to high level of disease cognition, and the education level, residence and access to disease knowledge are the main influencing factors.
RESUMEN
OBJECTIVE@#To explore the clinical outcomes of anteromedial combined with lateral locking plate for complex proximal humeral fractures in the eldery.@*METHODS@#From June 2018 to October 2020, 30 patients who underwent surgical treatment for Neer grade 3 to 4 proximal humeral fractures, including 8 males and 22 females, aged from 51 to 78 years old with an average of (61.5±7.5) years old. Of them, 15 patients had fractures fixed with anteromedial combined with lateral locking plate(ALLP group), whereas 15 received internal fixation with proximal humerus locking plate only(PHLP group). The clinical data, simple shoulder test (SST), humeral head height loss, varus angle and shoulder range of motion were compared between the two groups.@*RESULTS@#All fractures were healed. The follow-up time ranged from 12 to 24 months, with an average of(14.3±2.9) months. The operation time of ALLP group was longer than that of PHLP group (P<0.05). There was no significant difference in intraoperative blood loss between the two groups (P>0.05). There was no significant difference in SST score between the two groups at 1, 3 and 12 months after operation (P>0.05). In terms of radiographic measurement, there was no significant difference in humeral head height loss and varus angle between the two groups at 1 and 3 months after operation (P>0.05). At 12 months after operation, the height loss and varus angle of humeral head in ALLP group were lower than those in PHLP group (P<0.05). In shoulder range of motion, the range of forward elevation in ALLP group was larger than that in PHLP group 1 year after operation(P<0.05). There was no significant difference in external rotation between the two groups.@*CONCLUSION@#Anteromedial combined with lateral locking plate in the treatment of complex proximal humeral fractures in the elderly can increase the stability of the medial column and obtain a good fracture prognosis. But there are also disadvantages such as longer operation time, so it should be individualized according to the fracture type of the patient.

Global plastics production has been increasing year by year. Due to the large quantity of plastics and the difficulty of their degradation, plastics are continuously accumulated in the environment. Therefore, plastic waste has become one of the most serious threats to the global environment. Microplastics can be absorbed into organisms through the mouth, respiratory tract and skin, causing organ(intestine, liver) toxicity, reproductive and developmental toxicity, and neurotoxicity. Moreover, microplastics can also take up other pollutants distributed in the surrounding environment, such as heavy metals and organic pollutants, jointly exerting combined toxic effects. The extracts of microplastics, including microplastics unstable polymers and additives, also have toxic effects. The molecular mechanisms involved in the toxic effects induced by microplastics include oxidative stress, inflammation, disturbance of intestinal flora, disturbance of gene expression, and others.
RESUMEN
【Objective】 To analyze the data of non-small cell lung cancer (NSCLC) gene chip using the bioinformatics method, screen differential expression genes (DEGs), and explore the biomarkers related to the prognosis of NSCLC so as to provide a new target for the treatment of NSCLC. 【Methods】 The NSCLC gene chip data were downloaded from the GEO database and the common DEGs in the two datasets were screened by GEO2R tool and FunRich3.1.3 software. The DAVID database was used in GO analysis and KEGG analysis of the DEGs. The protein-protein interaction (PPI) network was constructed using the STRING database; Cytoscape 3.8.0 software was used to select the top 20 hub genes. Then Kaplan-Meier plotter was used to analyze the prognosis of the identified hub genes, and multiple external databases were used to verify the expressions of the hub genes and their relationship with prognosis. 【Results】 A total of 159 intersect DEGs were screened from the two datasets. A total of 20 hub genes were identified via PPI network. Survival analysis and validation results from multiple external databases showed that SPP1 was highly expressed in NSCLC tumor tissues and was significantly correlated with the patients’ poor prognosis (P<0.05). The subgroup analysis showed that SPP1 might cause the poor prognosis by affecting lymph node metastasis. 【Conclusion】 SPP1 may be a biomarker for evaluating the prognosis of NSCLC patients, providing a new idea for the targeted therapy of NSCLC.
RESUMEN
Objective:To evaluate the role of synapsin-Ⅰ phosphorylation in herkinorin-induced reduction of oxygen-glucose deprivation/restoration (OGD/R)-caused damage to cortical neurons and the relationship with conventional protein kinase C (cPKC)γ in newborn mice.Methods:Primary cortical neurons of cPKCγ + /+ and cPKCγ -/- mice (within 24 h after birth) were cultured for 7 days.Each type of neurons were then divided into 3 groups ( n=5 each) using a random number table method: control group (group C), OGD/R group and herkinorin group (group H). The neurons were subjected to oxygen-glucose deprivation (OGD) for 1 h followed by restoration of oxygen-glucose supply for 24 h. Herkinorin 10 μmol/L was added immediately after onset of OGD, the neurons were then incubated for 1 h, and herkinorin was washed out at the end of OGD in group H. At 24 h of oxygen-glucose restoration, cells were collected for measurement of the cell survival rate by methyl thiazolyl tetrazolium assay, and immunofluorescence was used to measure the number of neurites and the length of dendrites.Western blot was applied to detect the expression of phosphorylated synapsin-Ⅰ (p-synapsin-Ⅰ). Results:Compared with group C, the cell survival rate and the number of neurites were significantly decreased, the length of dendrites was shortened, and the expression of p-synapsin-Ⅰ was down-regulated in cPKCγ + /+ and cPKCγ -/- mice in group OGD/R and group H ( P<0.05). Compared with group OGD/R, the cell survival rate and the number of neurites were significantly increased, the length of dendrites was prolonged, the expression of p-synapsin-Ⅰ was up-regulated in cPKCγ + /+ mice in group H ( P<0.05), and no significant change was found in the parameters mentioned above in cPKCγ -/- mice in group H ( P>0.05). There was no significant differences in the expression of synapsin-Ⅰ in neurons among the three groups of cPKCγ + /+ mice and among the three groups of cPKCγ -/- mice ( P>0.05). Conclusion:Herkinorin can reduce OGD/R-caused damage to cortical neurons through decreasing cPKCγ membrane translocation and inhibiting synapsin-Ⅰ phosphorylation in newborn mice.
RESUMEN
Since December 2019, Corona Virus Disease (COVID-19), a new emerging infection disease occurred in Wuhan, has spread in 27 countries and regions. The clusters of many cases were reported with the epidemic progresses. We collected currently available information for 377 COVID-19 clusters (1 719 cases), excluded the hospital clusters and Hubei cases, during the period from January 1, 2020 to February 20, 2020. There were 297 family clusters (79%), case median 4; 39 clusters of dining (10%), case median 5; 23 clusters of shopping malls or supermarkets (6%), case median 13; 12 clusters of work units (3%), case median 6, and 6 clusters of transportation. We selected 325 cases to estimate the incubation period and found its range is 1 to 20 days, median was 7 days, and mode was 4 days. The analysis of the epidemic situation in a department store in China indicates that there is a possibility of patients as the source of infection during the incubation period of the epidemic. From February 5, 2020 to February 21, 2020, 634 persons were infected in the Diamond Princess Liner. All persons are susceptible to SARS-CoV-2. The older, patients during the incubation period and the worse environment may be the cause of the cases rising. The progress of the two typical outbreaks clearly demonstrates the spread of the early cases in Wuhan. Whatever happens, screening and isolating close contacts remains essential except for clinical treatment during the epidemic. Especially for the healthy people in the epidemic area, isolation is the key.

<p><b>OBJECTIVE</b>To retrospectively analyze the clinical data of 17 patients with bone cement leakage after percutaneous kyphoplasty and explore the leakage type and mid-term clinical effects.</p><p><b>METHODS</b>The clinical data of 17 patients with osteoporotic vertebral compression fractures occurred bone cement leakage after percutaneous kyphoplasty from October 2011 to October 2016 were collected. There were 7 males and 10 females, aged from 68 to 87 years old with an average of 78 years. All the patients had the history of low emergy trauma who had normal activity and full self-care for living before trauma, and complained with the lower back pain without signs and symptoms of nerve root injury after trauma. According to the anatomical location by images, the bone cement leakage pathways was confirmed, the preoperative and postoperative vertebral body height and Cobb angle were measured, the improvement of spinal stenosis were recorded. Preoperative and postoperative visual analogue scale (VAS) and Oswestry Disability Index(ODI) were used to evaluate pain and daily activities.</p><p><b>RESULTS</b>All the patients were followed up for 4 to 7 years with an average of 5.1 years. According to anatomical location by images, we found the bone cement leakage pathways of vertebral side type in 6 cases, intervertebral disc type in 3 cases, spinal canal type in 2 cases, vertebral pedicle type in 5 cases and mixed type in 1 case. Vertebral body height from preoperative(27.7±3.5)% restored to (56.4±2.5)% at final follow-up, and the kyphosis was corrected with Cobb angle from preoperative(45.3±4.2)° corrected to(18.3±3.1)° at final follow-up. VAS score decreased from preoperative 7.9±1.5 to 2.1±0.5 at final follow-up. ODI obviously restored from preoperative(49.1±7.5)% to (23.5±3.7)% at final follow-up. The nerve symptoms in lower limbs occurred in 2 cases, and the neurological symptom was disappeared after urgent symptomatic treatment and anaphase trophic nerve treating. Lower back pain occurred in 3 cases, including one case of unbearable pain, and the pain disappeared after symptomatic treatment.</p><p><b>CONCLUSIONS</b>Although the rate of bone cement leakage during percutaneous vertebral kyphoplasty is not low, the bone cement leakage has little influence on PKP surgery. Even if a little leakage occurred within the spinal canal during the surgery, spinal canal decompression will not be needed urgently. The significant clinical symptoms caused by leakage can basically disappear after treatment in mid-term follow-up.</p>
