Advances on cardiovascular effects of GLP-lRAs / 中国药理学通报

Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.

Treatment of spinal burst fractures with pedicle screw fixation at high altitude area / 中国骨伤

OBJECTIVE@#According to the characteristics of spinal burst fractures in high-altitude areas and the local medical conditions, to explore the clinical efficacy of short-segment fixation with pedicle screws combined with screw placement in injured vertebrae in the treatment of thoracolumbar burst fractures.@*METHODS@#From August 2018 to December 2021, 12 patients with single-vertebral thoracolumbar burst fractures without neurological symptoms were treated with injured vertebral screw placement technique, including 7 males and 5 females;aged 29 to 54 years old, with an average of(42.50±7.95) years old;6 cases of traffic accident injury, 4 cases of high fall injury, 2 cases of heavy object injury;2 cases of T11, 4 cases of T12, 3 cases of L1, 2 cases of L2, and 1 case of L3. In the operation, screws were first placed in the upper and lower vertebrae of the fracture, pedicle screws were placed in the injured vertebra, and connecting rods were installed, and the fractured vertebral body was reset by positioning and distraction. Visual analogue scale (VAS) and Japanese Orthopedic Association (JOA) scoring were used to evaluate the changes in pain and quality of life of patients, and the kyphotic correction rate and correction loss rate of the injured segment were measured by X-ray.@*RESULTS@#All operations were successful without significant intraoperative complications. All 12 patients were followed up, the duration ranged from 9 to 27 months, with an mean of (17.75±5.79) months. VAS at 3 days after operation was significantly higher than that at admission (t=6.701, P=0.000). There was significant difference in JOA score between 9 months after operation and at admission (t=5.085, P=0.000). Three days after operation, Cobb angle was (4.42±1.16)°, and the correction rate was (82±5)% compared with (25.67±5.71)° at admission. Cobb angle was (5.08±1.24) °at 9 months after operation, with a corrected loss rate of (16±13)%. No loosening or breakage of internal fixation was found.@*CONCLUSION@#Under the high-altitude hypobaric and hypoxic environment, the effect of the operation should be ensured while reducing the trauma. The application of the technique of placing screws on the injured vertebra can effectively restore and maintain the height of the injured vertebra, with less bleeding and shorter fixed segments, which is an effective method.

Lifestyle improvement and the reduced risk of cardiovascular disease: the China-PAR project / 老年心脏病学杂志（英文版）

BACKGROUND@#The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China).@*METHODS@#A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated.@*RESULTS@#A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98).@*CONCLUSIONS@#Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

Clinical effect of Kirschner wire intramedullary fixation in the treatment of pediatric both-bone forearm fractures at high altitude area / 中国骨伤

OBJECTIVE@#To explore the clinical effect of Kirschner wire intramedullary fixation in the treatment of both-bone forearm fractures in children of high altitude area.@*METHODS@#From August 2020 to December 2021, 19 children were treated with Kirschner wire intramedullary fixation including 11 males and 8 females, aged from 4 to 13 years old with an average of (8.16±2.71) years old. The course of disease was 1 to 10 days, with a mean of (4.11±2.51) d. First, close reduction was performed. If the reduction was unsuccessful, limited open reduction was performed, followed by Kirschner wire intramedullary fixation of the radius and ulna. The fracture healing was evaluated by X-ray after operation, and the curative effect was evaluated by Anderson forearm function score standard.@*RESULTS@#The wound healed well after operation, 2 cases had clinical manifestations of needle tail irritation after operation, and the symptoms disappeared after removing the internal fixation. The average follow-up time was(7.68±3.50) months (3 to 14 months). X-ray showed that all fracture healing in follow-up, Anderson forearm function score showed excellent in 16 cases, good in 2 cases and fair in 1 case at the final follow-up.@*CONCLUSION@#Children with fractures in plateau areas often have delayed medical treatment, lack of medical conditions and insufficient compliance. Based on these characteristics, Kirschner wire intramedullary fixation for the treatment of children's double forearm fractures has the advantages of small injury and rapid recovery. It is a kind of operation method that can be popularized.

The reduction value of lateral meniscus displacement and reduction rate after suture were calculated and compared between groups.@*RESULTS@#There was no significant difference between groups ( P>0.05) in the displacement values before modeling, after modeling, and after suture under different tensions. There was no significant difference between groups A and C ( P>0.05) in the reduction value of lateral meniscus displacement and reduction rate after suture under different tensions. The reduction value of lateral meniscus displacement and reduction rate after suture in group B were lower than those in groups A and C. The reduction value of lateral meniscus displacement under tension of 2 N and the reduction rates under tensions of 2, 4, and 6 N between groups A and B showed significant differences ( P<0.05). The reduction value of lateral meniscus displacement and the reduction rate under tensions of 2, 4, and 6 N between groups B and C showed significant differences ( P<0.05).@*CONCLUSION@#Suturing the anterior area of PH is the key to repairing type Ⅱc injury of lateral meniscus popliteal tendon area.

Management of congenital diaphragmatic hernia in preterm and low birth weight infants / 中华围产医学杂志

Objective:To investigate the treatment of preterm and low birth weight infants with congenital diaphragmatic hernia (CDH) and to share the experience.Methods:This retrospective study enrolled 117 newborns with CDH who underwent major surgery at Children's Hospital, Capital Institute of Pediatrics from May 1, 2011, to March 31, 2022. Based on gestational age and birth weight, the infants were divided into the preterm and/or low birth weight group (gestational age < 37 weeks and/or birth weight less than 2 500 g, n=41) and the control group (gestational age ≥ 37 weeks and birth weight ≥ 2 500 g, n=76). Furthermore, the preterm and/or low birth weight infants were divided into the thoracoscopic surgery subgroup ( n=31) and the open surgery subgroup ( n=10) according to the surgical approach. Statistical analysis of the data was performed using two independent sample t-tests, rank sum tests, Chi-square test, or Fisher's exact probability test. Results:Preoperative data showed that the Apgar scores at 1 min [7.0 (6.0-8.0) vs 9.0 (8.0-9.8), Z=－4.03] and 5 min [9.0 (8.0-10.0) vs 9.0 (9.0-10.0), Z=－2.13] of the preterm and/or low birth weight infants were both lower than those in the control group (both P<0.05), while the proportion of infants with moderate to severe pulmonary hypertension was higher [68.3% (28/41) vs 38.2% (29/76), χ 2=9.68, P<0.05]. There were no statistically significant differences between the two groups in terms of the proportion of thoracoscopic surgery, operation time, right diaphragmatic hernia, presence of hernia sac, grading of the defect, presence of liver herniation, and application of mesh (all P>0.05). Regarding the postoperative outcomes, the death rate in the preterm and/or low birth weiht group was higher compared to the control group [36.6% (15/41) vs 13.2% (10/76), χ 2=8.70, P<0.05]. Additionally, the time required to resume full enteral nutrition after surgery was longer in the preterm and/or low birth weight group than that in the control group [25 d (18-29 d) vs 16 d (10-25 d), Z=2.31, P<0.05]. The thoracoscopic subgroup had a lower mortality compared to the open surgery subgroup [25.8% (8/31) vs 7/10, P<0.05]. The thoracoscopic surgery subgroup had a higher Apgar score at 1 min after birth [(7.4±1.6) vs (6.0±2.2), t=2.20, P<0.05], later age at operation (hours after birth) [31.0 h (23.0-48.0 h) vs 17.0 h (4.7-24.5 h), Z=2.57, P<0.05], a lower proportion of infants operated within 24 hours after birth [32.3% (10/31) vs 8/10, P<0.05], and longer duration of operation [170.0 min (122.0-200.0 min) vs 110.0 min (87.3-120.0 min), Z=3.65, P<0.05]. Conclusions:In this study, a higher mortality in the preterm and/or low birth weight group compared to the control group was observed, which may be attributed to the higher proportion of neonates with moderate-severe pulmonary hypertension. The thoracoscopic diaphragmatic repair can be attempted for preterm and low birth weight infants who have relatively stable respiratory and circulatory functions.

Objective:To evaluate the necessity, safety and efficacy of endovascular treatment for cerebral infarction caused by middle cerebral artery (MCA) stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.Methods:The clinical and surgical data of patients with MCA atherosclerotic disease who underwent endovascular treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to October 2021 were retrospectively analyzed. A total of 6 patients with cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery were selected. The preoperative and postoperative clinical imaging characteristics, perioperative complications and follow-up of these 6 patients were summarized and evaluated.Results:After the endovascular treatment, the imaging of the lenticulostriate artery in all the 6 patients was clearer than that before the operation, and the number of main trunks of the lenticulostriate artery shown by imaging in 2 patients was more than that before operation. The computer tomography perfusion of 6 patients after the endovascular treatment showed that perfusion in the supply area of the lenticulostriate artery was significantly improved compared with pre-operation. No stroke, transient ischemic attack (TIA) and death occurred during the perioperative period. The time of clinical follow-up was 360 (322, 495) days, and there were no stroke, TIA or death occurring in the corresponding artery. All the 6 patients underwent imaging follow-up, of which 3 patients underwent digital subtraction angiography and 3 underwent CT angiography. The lumen of the target vessels showed patency in all patients.Conclusions:With rigorous imaging evaluation, endovascular treatment may be safe and effective for cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.

Cellular senescence and type 2 diabetes / 中华内分泌代谢杂志

Cellular senescence is a state in which cells enter permanent cell cycle arrest, which is characterized by senescence-associated secretory phenotype secretion, macromolecular damage, metabolic dysregulation and so on. Recent studies have shown a close relationship between cellular senescence and type 2 diabetes. On the one hand, the glycolipotoxic microenvironment of type 2 diabetes can accelerate cell senescence and accumulation. On the other hand, cellular senescence can promote the development of type 2 diabetes. For example, senescence of pancreatic β-cells leads to β-cell dysfunction and adipocytes senescence results in the secretion of pro-inflammatory cytokines, causing disturbances in lipid metabolism and exacerbating insulin resistance. Moreover, senescence of endothelial cells, retinal endothelial cells, and other cell types contributes to the occurrence of chronic complications in diabetes. Cellular senescence is not only an important factor in the onset of type 2 diabetes but also a consequence of its progression. Targeting cellular senescence holds promise as a new strategy for the treatment of type 2 diabetes.

Clinical and genetic analysis of five pedigree with maturity-onset diabetes of the young type 2 / 中华内分泌代谢杂志

Objective:To explore the clinical and molecular genetic characteristics of patients with maturity-onset diabetes of the young type 2(MODY2).Methods:Clinical data and laboratory results were collected from five MODY2 patients and their family members diagnosed in the Department of Endocrinology, Genetics, and Metabolism of Xi ′an Children′s Hospital in the recent two years. Whole exome sequencing was carried out on every proband to identify potential variants, then the suspected variants were verified with Sanger sequencing in family numbers.Results:Among the 5 probands, except for proband 4 who presented with polydipsia and polyuria, hyperglycemia in the rest of the children was accidentally identified. Urine routine, urinary protein, and blood lipid of the five probands were all normal, and HbA 1C was between 5.96% and 8.15%. Moreover, an important discovery in this study was that proband 5 had insulin resistance(IRS), which was different from previous studies. It was confirmed by genetic analysis that a glucokinase(GCK) gene variant existed in every MODY2 pedigree. There were four GCK variants in this study, including c. 146C>T(p.T49I), c. 1237T>G(p.Y413D), c. 683C>T(p.T228M) and c. 952G>T(p.G318W), among which the C. 1237T>G(P.y413d) and C. 952G>T(P.G318W) had not been reported till now. All probands received lifestyle intervention, and the blood glucose control was relatively stable. Conclusion:There is MODY2 patient complicated with IRS. MODY2 patients can be controlled well by lifestyle interventions. In addition, we discovered two novel variants of GCK, which extend the mutation spectrum of this gene.

Objective:To evaluate the feasibility, safety, treatment outcome, and the individualized surgical procedure selection of the interventional treatments of chylous leakage.Methods:From July 2019 to January 2022, the clinical data of 60 consecutive patients with chylous leakage underwent interventional treatment were respectively analyzed. The cases included chylothorax ( n=37), chylous ascites ( n=10), chyluria ( n=4), chylothorax combined with chylous ascites ( n=5), chylothorax combined with chylopericardium ( n=2), and pelvic chylous effusion ( n=2). Conservative treatment was considered to have failed for all patients. The lymphangiography was firstly performed to detect chylous leakage, then an individualized procedure was selected according to the lymphangiography results. The treatment outcomes and complications were recorded, and follow-up was performed. Results:Lymphangiography was technically successful in 55 of 60 patients (91.7%), and no cisterna chyli and thoracic duct opacification was observed in 5 patients. The procedures for the patients included lymphangiography alone ( n=23), thoracic duct embolization ( n=23), thoracic duct disruption ( n=5), lymphatic embolization for pelvic chylous effusion ( n=4), and balloon plasty for thoracic duct ( n=5). Clinical success was achieved in 53 of 60 cases (88.3%). The complication rate was 8.3% (5/60), and all complications were minor. The median follow-up time was 11 months (range 0.5-30 months) for 56 patients, and 4 patients were lost to follow-up. There was one patient presenting the reoccurrence of symptom, and 8 patients died. Conclusions:The interventional treatment of chylous leakage is safe with good outcomes and low complication rate. Individualized treatment procedures based on the lymphangiography findings is feasible and with good curative effect.

Correlation of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and D-dimer with the severity of acute cholangitis / 中国基层医药

Objective:To correlate neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and D-dimer (DD) with the severity of acute cholangitis.Methods:The clinical data of 96 patients with acute cholangitis who received treatment in Panjin Central Hospital from September 2019 to March 2021 were retrospectively analyzed. These patients were divided into three groups according to the severity of acute cholangitis: 36 patients with mild acute cholangitis (group A), 35 patients with moderate acute cholangitis (group B), and 25 patients with severe acute cholangitis (group C). The correlation between age, sex, NLR, PLR, DD, and the severity of acute cholangitis was compared among the three groups.Results:In groups A and B, the area under the receiver operating characteristic curve (AUC) showing the performance of DD, NLR, and PLR levels in predicting acute cholangitis was 0.800, 0.838, and 0.721, respectively, with the optimal cut-off value of 1.985 mg/L, 9.589, and 154.410, respectively. Among them, NLR had the largest AUC, and the highest sensitivity (82.9%), and had a high diagnostic value. In groups B and C, the AUC for DD, NLR, and PLR was 0.967, 0.915, and 0.543, respectively, with the optimal cut-off value of 6.000 mg/L, 22.390, and 264.220, respectively. DD and NLR had a diagnostic significance (both P < 0.05), but PLR had no diagnostic significance ( P > 0.05). The AUC for DD was the largest, and therefore DD had a great diagnostic significance. When NLR, PLR, and DD were jointly detected, the AUC was the highest and the diagnostic value was the highest. The AUC in groups A and B was 0.866, and that in groups B and C was 0.977. Conclusion:The levels of DD, NLR, and PLR increase in patients with acute cholangitis, which are related to the severity of the disease. DD, NLR, and PRL can be used as indicators to evaluate mild and moderate acute cholangitis, and NLR has the highest diagnostic value. DD and NLR can be used as indicators to evaluate moderate to severe acute cholangitis, and the effect of DD is superior to that of NLR. The combined detection of the three indicators can increase the value to evaluate the severity of acute cholangitis, and its effect is superior to that of a single detection. The combined detection of NLR, PLR, and DD is helpful for the clinical diagnosis and treatment of acute cholangitis.

Analysis on optimal cut-off values for prediction of lumbar spinal stenosis using lumbar pedicle thickness / 中国基层医药

Objective:To investigate the optimal cut-off values for the prediction of lumbar spinal stenosis using lumbar pedicle thickness.Methods:The clinical data of 64 patients with lumbar spinal stenosis (patient group) admitted to Binzhou Center Hospital from November 2019 to April 2021 and 48 healthy volunteers (healthy control group) who concurrently received routine physical examination involving lumbar spine MRI examination in the same hospital were retrospectively analyzed. Lumbar pedicle thickness was measured on T 2 weighted images of the L 5 vertebral body in the axial projection. Lumbar pedicle thickness was compared between groups using the independent sample t-test. The relationship between lumbar pedicle thickness and age change was analyzed using a one-way analysis of variance. The efficacy of lumbar pedicle thickness in the diagnosis of lumbar spinal stenosis was evaluated using the receiver operating characteristic (ROC) curve, optimal cut-off values, sensitivity, specificity, and the area under the ROC curve. Results:There was no significant correlation between lumbar pedicle thickness and age change ( P > 0.05). Lumbar pedicle thickness of patients with lumbar spinal stenosis was significantly higher than that of healthy controls [(13.25 ± 1.73) mm vs. (8.54 ± 1.88) mm, t = 13.75, P < 0.05]. ROC curve results showed that the optimal cut-off value was 10.50 mm, with a sensitivity of 95.3% and a specificity of 85.4. The area under the ROC curve was 0.963 (95% CI 0.928-0.998). Conclusion:The increase in lumbar pedicle thickness is related to the increase in the incidence of lumbar spinal stenosis. Lumbar pedicle thickness is an accurate, objective, and clear morphological parameter for the prediction of lumbar spinal stenosis. Application of lumbar pedicle thickness to predict lumbar spinal stenosis is innovative and scientific.

Objective A program-controlled flexible multi-point temperature measurement device was self developed for collection and analysis of skin temperature signals of diabetic patients and healthy subjects under resting and heating conditions so as to assess vasodilation function of the microcirculation, Methods With reference to the endothelial regulation spectrum of human body, wavelet analysis was performed on skin temperature signals, and the temperature fluctuation amplitudes in diabetic group and healthy control group were compared at different time periods after thermal stimulation. Results The temperature fluctuation amplitude in endothelial spectrum of diabetic group was smaller than that of healthy control group, and the decrease in skin temperature fluctuation after the power-off of thermal stimulation was remarkably smaller than that of control group, indicating that the response to thermal stimulation for diabetic patients was slower. Conclusions Vasodilation function can be quantitatively evaluated by using the fluctuation of skin temperature signals in endothelial spectrum band. Skin temperature monitoring is a potentially easy-implemented method for the health management and early diagnosis of microvascular diseases in diabetic patients.

Effects of aromatase inhibitors on the ocular surface microenvironment / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the effects of aromatase inhibitors(AIs)on the ocular surface microenvironment of the users.METHODS: A cross-sectional observational study was conducted. The study included postmenopausal women who received AIs treatment at galactophore department of our hospital from November 2022 to May 2023. Participants were divided into two groups based on the mechanism of AIs: the steroidal group and the non-steroidal group. The control group consisted of age-matched women who underwent occupational health examinations. All participants completed the ocular surface disease index(OSDI)questionnaire and underwent detailed ophthalmic examinations, including best-corrected visual acuity, intraocular pressure, axial length, corneal curvature, radius of curvature of curved lacrimal river surface, tear osmolarity, tear film break-up time, corneal fluorescein staining score, Schirmer Ⅰ test, and meibomian gland infrared score.RESULTS: There were no statistically significant differences in age, best-corrected visual acuity, intraocular pressure, axial length, and corneal curvature between control group and steroidal and non-steroidal group(P&#x003E;0.05). The duration of drug treatment between the steroidal group and the non-steroidal group also showed no statistically significant difference(P&#x003E;0.05). However, statistically significant differences were observed between the control group and the steroidal and non-steroidal group in OSDI scores, radius of curvature of curved lacrimal river surface, tear osmolarity, tear film break-up time, corneal fluorescein staining score, Schirmer Ⅰ test, and meibomian gland infrared score(P&#x003C;0.05). The Schirmer Ⅰ test also showed statistically significant differences between the steroidal group and the non-steroidal group(P&#x003C;0.05), while other data showed no statistically significant differences(P&#x003E;0.05).CONCLUSION: Postmenopausal patients receiving AIs treatment experienced significant changes in the ocular microenvironment, with both decreased tear secretion and excessive tear evaporation contributing to the occurrence of dry eye. Notably, patients receiving non-steroidal AIs treatment showed a more significant reduction in main lacrimal gland secretion.

Association between Fruit and Vegetable Intake and Arterial Stiffness: The China-PAR Project / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to investigate the association between fruit and vegetable intake and arterial stiffness.@*METHODS@#We conducted a cohort-based study comprising 6,628 participants with arterial stiffness information in the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) project. A semi-quantitative food-frequency questionnaire was used to assess baseline (2007-2008) and recent (2018-2021) fruit and vegetable intake. We assessed changes in fruit and vegetable intake from 2007-2008 to 2018-2021 in 6,481 participants. Arterial stiffness was measured using the arterial velocity-pulse index (AVI) and arterial pressure-volume index (API). Elevated AVI and API values were defined according to diverse age reference ranges.@*RESULTS@#Multivariable-adjusted linear regression models revealed that every 100 g/d increment in fruit and vegetable intake was associated with a 0.11 decrease in AVI ( B= -0.11; 95% confidence interval [ CI]: -0.20, -0.02) on average, rather than API ( B = 0.02; 95% CI: -0.09, 0.13). The risk of elevated AVI (odds ratio [ OR] = 0.82; 95% CI: 0.70, 0.97) is 18% lower in individuals with high intake (≥ 500 g/d) than in those with low intake (< 500 g/d). Furthermore, maintaining a high intake in the past median of 11.5 years of follow-up was associated with an even lower risk of elevated AVI compared with a low intake at both baseline and follow-up ( OR = 0.64; 95% CI: 0.49, 0.83).@*CONCLUSION@#Fruit and vegetable intake was negatively associated with arterial stiffness, emphasizing recommendations for adherence to fruit and vegetable intake for the prevention of arterial stiffness.

Research progress of celastrol on the prevention and treatment of metabolic associated fatty liver disease / 生理学报

Metabolic associated fatty liver disease (MAFLD) is a liver disease with hepatocyte steatosis caused by metabolic disorders, which is closely related to obesity, diabetes, metabolic dysfunction, and other factors. Its pathological process changes from simple steatosis, liver inflammation to non-alcoholic steatohepatitis (NASH), and then leads to liver fibrosis, cirrhosis, and liver cancer. At present, no specific therapeutics are available for treatment of MAFLD targeting its etiology. Celastrol is the main active component of the traditional Chinese medicine Celastrus orbiculatus Thunb. In recent years, it has been found that celastrol shows important medicinal value in regulating lipid metabolism, reducing fat and weight, and protecting liver, and then ameliorates MAFLD. This article reviews the related research progress of celastrol in the prevention and treatment of MAFLD, so as to provide a reference for the comprehensive development and utilization of celastrol.

The genotypes of rs12894524 locus were TT (1.3%), TG (13.5%) and GG (85.2%), and the frequency of T and G allele was 8.1% and 91.9%, respectively. rs8022522 and rs12894524 locus genotypes and allele frequencies were significantly different from HapMap-CEU, HapMap- YRI and HapMap-TSI (P<0.05). Compared with HapMap-JPT and HapMap-CHB, there was no significant difference in genotype or allele frequency between the two sites (P>0.05). As for the blood lipid level among the three genotypes in rs8022522, the level of high density lipoprotein cholesterol (HDL-C) with GG genotype was significantly different from that in AG group (P<0.05). 【Conclusion】 The polymorphisms of rs8022522 and rs12894524 of miR-208 gene in Guangxi population are different from those in other regions to varying degrees. The polymorphism of rs8022522 locus is related to the level of HDL-C.

Research progress of biomimetic nano drug delivery system in nervous system disease / 药学学报

Brain delivery of drugs remains challenging due to the presence of the blood-brain barrier (BBB). With advances in nanotechnology and biotechnology, new possibilities for brain-targeted drug delivery have emerged. Biomimetic nano drug delivery systems with high brain-targeting and BBB-penetrating capabilities, along with good biocompatibility and safety, can enable 'invisible' drug delivery. In this review, five different types of biomimetic strategies are presented and their research progress in central nervous system disorders is reviewed. Finally, the challenges and future prospects for biomimetic nano drug delivery systems in intracerebral drug delivery are summarized.

Synthesis, evaluation and proteomic analysis of PROTAC based on parthenolide / 药学学报

As a natural product with a long history of medicinal use, parthenolide has aroused great interest of chemists and biologists. Existing studies have shown that it has anti-inflammatory, antitumor and other pharmacological activities, and also revealed its action on NF-κB signaling pathway, DNMT1 enzyme and Wnt/β-catenin signaling pathway. But its biological targets remain to be elucidated systematically. Proteolysis Targeting Chimeras (PROTAC) provides a new strategy for target discovery of natural products, which can be used to explore the panorama of protein changes in cells through proteomic investigation, so as to analyze their potential targets. Based on this idea, current study designed and synthesized 20 parthenolide-derived degraders. After measured their antitumor activity in vitro, selected compounds were carried out the proteomic experiment. Finally, 139 down-regulated differentially expressed proteins were identified and the discovery of parthenolide interacting protein was preliminarily explored.
