OBJECTIVE To explore the effects of narrative pharmacy management on medication compliance， negative emotions， and quality of life in patients with cardiovascular disease complicated with negative emotions. METHODS A total of 49 patients with drug use problems and negative emotions attending the cardiovascular pharmacy clinic of Wuhan First Hospital from February to August 2023 were selected as the study objects， narrative pharmacy model was applied for patient management during their visits； pharmaceutical care and emotional management were performed after 2 weeks of treatment and a follow-up visit was conducted to evaluate and record the management effect one month later. RESULTS Adopting a narrative pharmacy management model， 49 patients were involved in 114 drug related consultation questions. Compared with the visit， after one month of management， the number of medication types taken by patients significantly decreased [4.00 （2.00， 6.00） vs. 3.00 （1.50， 5.00）， P＜0.05]， the incidence of adverse reactions significantly decreased （32.65% vs. 2.04%， P＜0.001）， the rate of blood pressure and lipid compliance significantly increased （30.61% vs. 95.92%， P＜0.001）， and the score of the patient’s medication compliance significantly improved （[ 3.94±2.44） vs. （6.78±2.07）， P＜0.01]. The depression score significantly decreased [3.00 （2.00， 4.50） vs. 2.00 （0.00， 3.00）， P＜0.001]， the anxiety score significantly reduced [3.00 （2.00， 4.50） vs. 1.00 （0.00， 2.00）， P＜0.001]， quality of life score was significantly improved [22.00 （19.00， 22.00） vs. 23.00 （23.00， 24.50）， P＜0.01]. In the satisfaction survey， there was a slight increase in the overall satisfaction proportion （91.84% vs. 97.96%， P＞0.05）. CONCLUSIONS The application of narrative pharmacy in cardiovascular pharmacy clinic can improve patient compliance， reduce adverse drug reactions， enhance the effectiveness of drug treatment， avoid drug interactions， effectively improve the anxiety and depression， and ultimately improve the quality of life.

Objective@#To explore the effects of community building environment and sports with fitness APP usage and their interactions on teachers exercise habits in the Yangtze River Delta Region, so as to provide a scientific basis for the development of a sports and health promotion intervention program for teachers.@*Methods@#A total of 2 530 in service teachers from four provinces and cities in the Yangtze River Delta region, namely, Shanghai, Zhejiang, Jiangsu and Anhui Province, were sampled in May-June 2023 by using convenient cluster random sampling method. Self designed questionnaire was used to collect the basic information of the surveyed teachers, Physical Activity Building Environment Evaluation Questionnaire and the Sports with Fitness APP Usage Questionnaire were used to measure the teachers subjective perception of the community building environment and the usage of sports with fitness APP, respectively. Physical Exercise Habituation Scale was used to assess the level of exercise habits. Logistic regression models were applied to analyze the effects of community building environment and sports with fitness APP usage on physical exercise, and the interaction effects were analyzed by using additive and multiplicative models.@*Results@#Among all the teachers surveyed, 658 of them reported good physical exercise habits (26.0%), and differences in the rate of physical activity habit formation by gender, age, years of teaching, as well as subject of teaching were statistically significant ( χ 2=42.94, 39.73, 35.47, 218.23 , P <0.05). Teachers with physical exercise habits had significantly higher community building environment scores and sports and fitness APP use than teachers without exercise habits ( t =12.17,16.54, P <0.05). Adjusting for the confounders of age, gender, years of teaching experience, and subjects taught, multifactorial unconditional Logistic regression analysis showed that the probability of teachers having good physical exercise habits increased by 22% for every 1-point increase in the community building environment score on average ( OR =1.22, 95% CI =1.11-1.40), and the probability of teachers having good physical exercise habits increased by 16% for every 1-point increase in the sports with fitness APP score on average ( OR = 1.16 , 95% CI =1.03-1.31) ( P <0.05). Interaction analyses showed that there was an additive interaction between the effects of community building environment and sports and fitness APP use on teachers physical exercise habits after adjustment, and the 95% CI for RERI , API and SI were 1.17 -1.65, 0.12-0.46 and 1.78-3.33 ( P <0.05), respectively, and there was no multiplicative interaction ( P >0.05).@*Conclusions@#The community building environment and the usage of sports & fitness APP show impacts in the formation of teachers physical exercise habits in the Yangtze River Delta region, and there is an interaction effect. Enhancing the construction of smart sports centers around the community can provide a high quality external environment for the physical exercise habits formation.
RESUMEN
Background Anxiety and depression are common perinatal mental health issues that often occur together and can have serious negative effects on both maternal and infant health. Objective To examine the relationships between lifestyle factors and comorbid anxiety and depression (CAD) among pregnant women in Shanghai. Methods The study estimated the prevalence of CAD during the first, second, and third trimesters of pregnancy using the Self-rating Anxiety Scale (SAS) and Center for Epidemiological Studies-Depression (CES-D) based on data from the China National Birth Cohort (CNBC) embryonic-derived diseases with assisted reproductive technology (ART) sub-cohort. Information on demographics, sleep status, nutritional intake, and exercise during each trimester was collected through self-made questionnaires, the Pittsburgh Sleep Quality Index (PSQI), and the Food Frequency Questionnaire (FFQ). Lifestyle factors (such as sleep status, nutritional intake, and exercise during each trimester) were analyzed using logistic regression and generalized linear mixed models (GLMM) to determine their impacts on the prevalence of CAD (yes or no) among pregnant women. Results A total of 2876 pregnant women were included in this study. The prevalence of CAD was 10.6% (305), 3.6% (103), and 5.5% (159) in the first, second, and third trimesters of pregnancy, respectively. The logistic regression analysis revealed that poor sleep quality throughout the entire pregnancy were statistically associated with an increased prevalence of CAD, and the odds ratios (OR) with 95% confidence intervals (CI) were 2.817 (1.845, 4.301), 2.840 (1.855, 4.347), and 9.316 (5.835, 14.876) for the first, second, and third trimesters, respectively, when compared to good sleep quality. Additionally, compared to an intake frequency of 7 times per week, the frequency of egg intake ≤3 times per week in the first trimester (OR=2.025, 95%CI: 1.197, 3.425) and the frequency of egg intake of 4–6 times per week (OR=1.896, 95%CI: 1.117, 3.216) or ≤3 times per week (OR=1.906, 95%CI: 1.082, 3.357) in the third trimester were associated with an increased risk of CAD (P<0.05). Moreover, when compared to a frequency of exercise >3 times per week, never or almost never exercising in the second trimester (OR=2.218, 95%CI: 1.220, 4.035) was associated with an increased risk of CAD (P<0.05). The GLMM analysis also demonstrated a significant association between poor sleep quality, lower exercise frequency, or lower intake frequency of vegetables, eggs, or milk and an increased risk of CAD (P<0.05). Conclusion The prevalence of CAD among pregnant women in Shanghai follows a U-shaped distribution, with the highest rate occurring in early pregnancy and the lowest rate in mid-pregnancy. Factors such as poor sleep quality, inadequate intake of vegetables, eggs, or milk, and lack of exercise during pregnancy may increase the risk of CAD. Implementing lifestyle interventions during pregnancy could potentially reduce the risk of mental health problems and improve the overall health of both mothers and babies.

RESUMEN
AIM: To investigate the effect of inhibiting Ca2+/calmodulin-dependent protein kinase Ⅱ(CAMKⅡ)expression in adult retinal pigment epithelial cell line-19(ARPE-19)cells on the migration, invasion, and tube formation of human umbilical vein endothelial cells(HUVECs)in a non-contact co-culture system.METHODS: RNA sequencing was performed on ARPE-19 cells overexpressing CAMKⅡ-δ, and bioinformatics was used to analyze the biological functions of the differentially expressed genes. Transwell inserts was used to construct a non-contact co-culture system of ARPE-19 and HUVECs. The experimental groups included: blank group: only HUVECs were inoculated without ARPE-19 cells; control group: ARPE-19 and HUVECs cells were co-cultured with complete medium; AIP group(CAMKⅡ inhibition group): ARPE-19 cells in AIP(160 nmol/L)were co-cultured with HUVECs in complete medium. The migration, invasion and tube formation abilities of HUVECs were detected. The protein expression levels of CAMKⅡ/AMPK/mTOR/VEGFA were detected by Western blotting.RESULTS:Bioinformatics analysis found that the differentially expressed genes could affect biological processes such as cell growth and death and cell movement. The scratch test and transwell migration test showed that the relative mobility of HUVECs in the AIP group was significantly lower than that in the control group(all P<0.05). However, the invasion and tube formation assay showed that the relative invasion rate and tube formation rate of the AIP group were not significantly different from those of the control group(both P>0.05). Western blotting results showed that the expression levels of CAMKⅡ, P-mTOR, and VEGFA proteins in the AIP group were significantly lower than those in the control group, while the expression level of the P-AMPK protein was significantly higher than that in the control group(all P<0.05).CONCLUSION:In the non-contact co-culture system, inhibition of CAMKⅡ expression in ARPE-19 cells significantly reduced the migration ability of HUVECs, but it cannot change the invasion and tube formation ability, which may be achieved by AMPK/mTOR/VEGFA.

Objective@#The association between school bullying and attention deficit hyperactivity disorder (ADHD) symptoms among students in primary schools and the moderating role of gender was explored to provide scientific evidence for the prevention and control of school bullying.@*Methods@#A total of 4 764 students from 2 primary schools in Wuhan were selected using the convenience sampling method in March 2023. The Olweus Bully/Victim Questionnaire and Strengths and Difficulties Questionnaire were used. A Pearson χ 2 test was used to compare differences in school bullying rates among children with and without ADHD symptoms. Pearson correlation analysis and Process 3.3 were used to analyse the association between ADHD symptoms, and school bullying behaviour and the moderating role of gender.@*Results@#The reported rate of bullying victims in primary schools was 24.2% and the rate of bullying perpetration was 3.8%. The rate of ADHD symptom detection among primary school students was 5.9%. ADHD symptoms were positively associated with bullying and bullying victim behaviour ( r =0.16, 0.27, P <0.01). Specifically, the association between ADHD symptoms and bullying behavior tended to be stronger among boys than girls ( β boy =0.17, t =11.13; β girl =0.07, t =4.11, P <0.01).@*Conclusions@#ADHD symptoms are an important factor influencing school bullying behaviors in students, and gender moderates the association. In the process of preventing and controlling school bullying, ADHD symptoms and gender differences should be emphasized and comprehensive interventions should be implemented.
RESUMEN
Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.
RESUMEN
Objective To summarize the effect of the timing of lung transplantation and related treatment measures on clinical prognosis of patients with paraquat poisoning. Methods Clinical data of a patient with paraquat poisoning undergoing bilateral lung transplantation were retrospectively analyzed. Clinical manifestations, auxiliary examination, diagnosis and treatment of this patient were summarized and analyzed. Results A 17-year-old adolescent was admitted to hospital due to nausea, vomiting, cough and systemic fatigue after oral intake of 20-30 mL of 25% paraquat. After symptomatic support treatment, the oxygen saturation was not improved, and pulmonary fibrosis continued to progress. Therefore, sequential bilateral lung transplantation was performed under extracorporeal membrane oxygenation (ECMO). After postoperative rehabilitation and active prevention and treatment for postoperative complications, the patient was discharged at postoperative 50 d. Conclusions The timing of lung transplantation after paraquat poisoning may be selected when the liver and kidney function start to recover. Active and targeted prevention of potential pathogen infection in perioperative period and early rehabilitation training contribute to improving clinical prognosis of lung transplant recipients.
RESUMEN
AIM: To compare the short-term postoperative visual acuity, visual disturbance phenomena, and spectacle independence rate in patients who underwent monocular implantation with trifocal, multifocal, or extended range of vision intraocular lens(IOL).METHODS: A retrospective analysis was conducted on 67 cataract patients(67 eyes)who underwent phacoemulsification cataract extraction combined with IOL implantation from March 2019 to December 2022. A total of 35 cases(35 eyes)received Symfony extended range of vision IOL implantation, 21 cases(21 eyes)received AcrySof IQ ReSTOR +3D multifocal IOL, and 11 cases(11 eyes)received AcrySof IQ PanOptix trifocal IOL. The preoperative uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), and uncorrected near visual acuity(UNVA)and 3 mo postoperatively were documented. Moreover, defocus curves, visual disturbance phenomena, and spectacle independence rates were recorded at 3 mo postoperatively.RESULTS: At 3 mo postoperatively, no statistically significant differences were observed in UDVA among the three groups(P&#x003E;0.05). A comparison of UIVA showed superior results in the Symfony and PanOptix groups compared to the ReSTOR group(all P&#x003C;0.01). The UNVA of both the ReSTOR and PanOptix groups outperformed the Symfony group(all P&#x003C;0.01). The defocus curves indicated that in the intermediate vision range(-1.00 to -1.50 D), the Symfony group exhibited better performance than the ReSTOR group(P&#x003C;0.05); while in the near vision range(-2.50 to -3.50 D), the ReSTOR group was superior to the Symfony group(P&#x003C;0.05). The PanOptix group demonstrated superior visual acuity in the near vision range(-2.00 to -3.50 D)compared to the Symfony group(P&#x003C;0.05)and was also superior in the intermediate vision range(-1.00 to -2.00 D)compared to the ReSTOR group(P&#x003C;0.05). No significant differences were observed in the incidence of glare or halo and binocular interference phenomena among the three groups(P&#x003E;0.05). The PanOptix and ReSTOR groups exhibited a higher spectacle independence rate compared to the Symfony group(P&#x003C;0.0167).CONCLUSION: Compared to Symfony extended range of vision IOL and ReSTOR multifocal IOL, PanOptix trifocal IOL offers a balanced approach to distance, intermediate, and near visual acuity, without a high incidence of glare and halo, and with a higher spectacle independence rate. Caution is still advised when considering monocular implantation with presbyopia-correcting IOLs.
RESUMEN
Background@#and Purpose To evaluate whether the thrombus enhancement sign (TES) can be used to differentiate embolic large vessel occlusion (LVO) from in situ intracranial atherosclerotic stenosis (ICAS)-related LVO in the anterior circulation of patients with acute ischemic stroke (AIS). @*Methods@#Patients with LVO in the anterior circulation who underwent both non-contrast computed tomography (CT) and CT angiography and mechanical thrombectomy were retrospectively enrolled. Both embolic LVO (embo-LVO) and in situ ICAS-related LVO (ICAS-LVO) were confirmed by two neurointerventional radiologists after reviewing the medical and imaging data. TES was assessed to predict embo-LVO or ICAS-LVO. The associations between occlusion type and TES, along with clinical and interventional parameters, were investigated using logistic regression analysis and a receiver operating characteristic curve. @*Results@#A total of 288 patients with AIS were included and divided into an embo-LVO group (n=235) and an ICAS-LVO group (n=53). TES was identified in 205 (71.2%) patients and was more frequently observed in those with embo-LVO, with a sensitivity of 83.8%, specificity of 84.9%, and area under the curve (AUC) of 0.844. Multivariate analysis showed that TES (odds ratio [OR], 22.2; 95% confidence interval [CI], 9.4–53.8; P<0.001) and atrial fibrillation (OR, 6.6; 95% CI, 2.8–15.8; P<0.001) were independent predictors of embolic occlusion. A predictive model that included both TES and atrial fibrillation yielded a higher diagnostic ability for embo-LVO, with an AUC of 0.899. @*Conclusion@#TES is an imaging marker with high predictive value for identifying embo- and ICAS-LVO in AIS and provides guidance for endovascular reperfusion therapy.
RESUMEN
OBJECTIVE To provide reference for strengthening the quality of pharmaceutical care in retail chain pharmacies and the professional capabilities of licensed pharmacists， and to meet the public’s pharmaceutical care needs. METHODS A combination of questionnaire survey and informant interview was used to investigate the general information of licensed pharmacists in retail chain pharmacies in Guangdong province， the implementation of pharmaceutical care， the competence and knowledge status of the surveyed licensed pharmacists， and the factors affecting the development of pharmaceutical care. RESULTS & CONCLUSIONS A total of 444 questionnaires were sent out and 326 effective questionnaires were collected， with an effective recovery rate of 73.42%. Among 326 surveyed licensed pharmacists， a college degree or higher accounted for 40.18%， and the pharmacy major or related accounted for 79.75%. A total of 185 （56.75%） of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked had established specified areas of pharmaceutical care； 320 （98.16%）， 137 （42.02%） and 181 （55.52%） of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked could provide services such as rational medication guidance for patients， decocting traditional Chinese medicines and establishing health records， etc. The self-assessment scores of the surveyed licensed pharmacists were significantly higher than 3 （median） for competence and knowledge level， but the self-assessment scores for medication therapy management competence and pharmaceutical care practice were relatively low. The surveyed licensed pharmacists believed that the main factors affecting the development of pharmaceutical care in retail chain pharmacies included patients’ lack of trust or cooperation （196， 60.12%）， sales performance requirements （170， 52.15%）， and heavy daily workload （165， 50.61%）. It is recommended that relevant authorities expedite the legislative process of the Pharmacist Law， optimize the continuing education system for licensed pharmacists， and implement a star-rating evaluation system for pharmaceutical care capabilities in pharmacies， so as to encourage retail chain pharmacies and licensed pharmacists to pursue a more specialized development path. At the same time， pharmaceutical retail chain enterprises should shift their business mindset， increase investment in pharmaceutical care， enhance the professional atmosphere in the pharmacies， optimize the compensation structure for licensed pharmacists， and elevate the pharmaceutical care capabilities of both the pharmacies and licensed pharmacists to fulfill the pharmaceutical care needs of the public.
RESUMEN
OBJECTIVE To explore the intestinal absorption characteristics of saikosaponins. METHODS Based on everted intestinal sac model， using accumulative absorption amount （Q） and absorption rate constant （Ka） as indexes， UHPLC-MS/MS technique as a method， the absorption of saikosaponin A， B2， C， D and F from total saponins of Bupleurum chinense （8 g/mL， by crude drug） in the duodenum， jejunum and ileum was detected. RESULTS The correlation coefficients （r） of the regression equations for the absorption of saikosaponins A， B2， C and F in the duodenum， jejunum and ileum were all higher than 0.95， while the r of saikosaponin D in the above intestinal segments was lower than 0.95； compared with the absorption of the same composition in the duodenum， the Q and Ka of saikosaponin A and C circulating in jejunum and ileum for 120 min， as well as the Q and Ka of saikosaponin F circulating in the ileum for 120 min were significantly decreased （P＜0.05）. CONCLUSIONS Saikosaponin A and the other 4 saikosaponins are all absorbed in the duodenum， jejunum and ileum； among them， saikosaponin A， B2， C and F are linearly absorbed， which conforms to the zero-order absorption characteristics， but saikosaponin D shows non- linear absorption.
RESUMEN
We used network pharmacology to predict the mechanism in the treatment of rheumatoid arthritis (RA) via modified Gan Cao Fu Zi Decoction (GCFZ), and validated the results of the analysis and explored the pharmacodynamic effects of GCFZ through animal experiments. Firstly, TCMID, SymMap, HERB, STITCH and GEO databases were utilized to obtain the target genes of GCFZ for the treatment of RA, which yielded a total of 1 250 differentially expressed genes for RA, 534 genes for GCFZ targets and 83 intersecting genes. Then functional enrichment analysis of the intersecting genes was performed through GO and KEGG databases, and the results revealed that GCFZ and its active ingredients mainly functioned through cytokine pathways, where chemokine signaling pathway and tumor necrosis factor (TNF) signaling pathway were enriched with a high number of genes. Cytoscape 3.8.0 software was used to construct the drug-target-disease network and screen key proteins, which included TNF, C-X-C chemokine ligand 8 (CXCL8), C-X-C chemokine ligand 10 (CXCL10), C-C chemokine ligand 5 (CCL5), C-X-C chemokine ligand 2 (CXCL2) and C-X-C chemokine receptor type 4 (CXCR4). The molecular docking technology was used to confirm the binding ability of the main active ingredients of GCFZ to the core proteins. Additionally, the therapeutic effects of GCFZ in low (4 g·kg-1), medium (8 g·kg-1) and high (16 g·kg-1) dose groups were investigated by constructing the collagen-induced arthritis (CIA) rat model. X-ray imaging approach, HE staining and Safranin O-Fast Green staining showed that GCFZ treatment significantly improved bone destruction, synovial hyperplasia and cartilage damage in CIA rats, while immunofluorescence results showed that GCFZ treatment could regulate the expression of TNF, CXCL8 and CCL5. In summary, our results indicate that GCFZ contains a variety of small molecule pharmacodynamic substances, which can exert therapeutic effects via multiple targets and pathways, and obviously reduce the symptoms of arthritis in CIA rats. This animal experiment of our research was approved by the Experimental Animal Management and Ethics Committee of Bengbu Medical College.
RESUMEN
Objective To investigate the intra-patient variability (IPV) of tacrolimus trough concentrations and its effect on serum creatinine (Scr) level in kidney transplant recipients treated with nematvir/ritonavir. Methods Clinical data of 41 kidney transplant recipients infected by SARS-CoV-2 and treated with nematvir/ritonavir were collected. The usage of nematvir/ritonavir and tacrolimus was summarized. The distribution of tacrolimus trough concentrations and the attainment rate of target concentration were analyzed. The correlation between the IPV distribution of tacrolimus trough concentrations and the changes of Scr level was determined. Results Among 41 kidney transplant recipients, 46%(19/41) were given with full- and low-dose nematvir/ritonavir, and 7%(3/41) were given with high-dose nematvir/ritonavir. Use of tacrolimus was discontinued at 24 h before nematvir/ritonavir treatment in 95%(39/41) patients, and at 24 h after use of nematvir/ritonavir in 5%(2/41) patients. Tacrolimus was given at least 3 d after the 5-d course of nematvir/ritonavir in all patients. The attainment rate of tacrolimus trough concentration was 73%(30/41), 30%(3/10), 48%(15/31), 35%(11/31) and 53%(16/30) before, during, 1 week, 2 weeks and 1 month after use of nematvir/ritonavir, respectively. The median IPV was 35%(23%, 51%). Spearman correlation analysis showed that the increase of Scr level was positively correlated with IPV (rs=0.400 7, P=0.028 2). Conclusions The attainment rate of tacrolimus trough concentration is declined in kidney transplant recipients treated with nematvir/ritonavir. The IPV of tacrolimus trough concentrations is elevated. The recipients with higher IPV are prone to an elevation in Scr level.
RESUMEN
Obesity is a chronic， recurrent， and progressive metabolic disorder characterized by the abnormal or excessive accumulation of body fat caused by multiple factors such as genetics， dietary structure， lifestyle and behavior， psychology， environment， and society， leading to an energy surplus. Obesity is a major risk factor that increases the risk of developing various chronic diseases， including type 2 diabetes， hypertension， cardiovascular diseases， stroke， and certain malignancies. The global incidence of obesity is increasing year by year. With the continuous improvement of people's living standards， more than half of adults in China are now overweight or obese， posing a serious threat to people's health and increasing the social and economic burden. It has become a pressing major public health issue that needs to be addressed urgently. The concept of obesity can be traced back to the Huangdi’s Internal Classic （Huang Di Nei Jing）， which describes it as "the problems in fat and affluent people are caused by excessive taking of rich food"， and suggests that ''frequent intake of rich and greasy foods can produce interior heat. Sweet flavor causes chest fullness. That is why its spleen-Qi flows upwards and changes into consumption-thirst disease. It can be treated by Eupatorii Herba which is used to remove stagnant Qi''. The stagnant qi is caused by the transformation failure of rich and greasy food and wine， so obesity is the disease of stagnant qi. Obesity is caused by indulging in rich and greasy food， wine， spicy and flavorful foods， raw and cold foods， and sweet and greasy foods， or overeating and leading a sedentary lifestyle， staying up late， or experiencing emotional imbalances such as excessive joy， anger， worry， pensiveness， and fear. It can also be caused by congenital abnormalities， leading to improper functioning of the spleen and stomach， dysregulation of the absorption and secretion of the small intestine， and the accumulation of stagnant Qi in the organs and muscles， resulting in a plump physique. The intake of food and drink depends on the functions of the stomach in receiving and decomposing， the small intestine in absorbing and secreting， and the spleen in transforming and transporting. The affected organs in obesity are the spleen， stomach， and small intestine. Orchids， specifically Eupatorii Herba and Lycopi Herba， are aromatic herbs that can regulate the smooth flow of Qi， eliminate stagnation， and cleanse impurities. In a broader sense， any aromatic and pungent substance that can invigorate the spleen， promote clarity， harmonize the stomach， reduce turbidity， and assist in the normal secretion and absorption functions of the small intestine， thereby eliminating excess， is referred to as orchid. Therefore， the treatment principle for obesity is to use ''orchids to eliminate stagnant Qi''， aiming to regulate the functions of the spleen， stomach， and small intestine using aromatic and pungent substances， gradually eliminating excessive dampness， phlegm， turbidity， and heat， and restore the balance of the middle energizer. This way， individuals who are obese can achieve a non-obese state.
RESUMEN
ObjectiveTo investigate the effect of modified Huangqi Guizhi Wuwutang （MHGW） on the protein and mRNA expression of B-cell lymphoma-2-associated X protein （Bax） and cysteinyl aspartate specific proteinase-12 （Caspase-12） related to the apoptosis of sciatic nerve cells in diabetes rats to explore the mechanism of MHGW in the treatment of peripheral neuropathy in diabetes. MethodAnimal experiments were conducted. A diabetes model was induced in sixty male sprague-dawley （SD） rats by feeding on a high-sugar and high-fat diet combined with streptozotocin （STZ） intraperitoneal injection. Rats with random blood glucose levels ≥ 16.7 mmol·L-1 for three consecutive days were considered to have successfully developed diabetes. Forty-eight rats that successfully developed diabetes were randomly divided into a model group， an α-lipoic acid group （0.026 8 g·kg-1·d-1）， a high-dose MHGW group （2.5 g·kg-1·d-1）， and a low-dose MHGW group （1.25 g·kg-1·d-1）， with 12 rats in each group. Another 10 rats were assigned to the normal group. Body weight and random blood glucose levels of the rats were monitored. At the end of a 16-week intervention period， the sciatic nerve conduction velocity of the rats was measured using the Key point electromyography collection system. The protein and mRNA expression of Bax and Caspase-12 in the sciatic nerve cells was detected by Western blot analysis and real-time quantitative polymerase chain reaction （Real-time PCR）， respectively. ResultCompared with the normal group， the model group showed a significant decrease in body weight （P<0.01） and a significant increase in random blood glucose levels （P<0.01）. After a 16-week intervention， compared with the model group， the high-dose MHGW group exhibited a significant increase in body weight （P<0.05）， while there were no statistically significant differences in body weight changes among the other treatment groups. Random blood glucose levels significantly decreased in all treatment groups （P<0.01）. After 16 weeks of intervention， compared with the normal group， the model group had significantly reduced motor and sensory nerve conduction velocities （P<0.01）. Compared with the model group， all treatment groups showed significant increases in motor and sensory nerve conduction velocities （P<0.05， P<0.01）. The expression of Bax and Caspase-12 proteins in the sciatic nerve cells was significantly elevated in the model group compared with that in the normal group （P<0.01）. In contrast， all treatment groups showed significant reductions in the expression of Bax and Caspase-12 proteins in the sciatic nerve cells as compared with that in the model group （P<0.01）. The expression of Bax and Caspase-12 mRNA in the sciatic nerve cells significantly increased in the model group compared with that in the normal group （P<0.01）. Compared with the model group， the α-lipoic acid group and the high-dose MHGW group showed significant reductions in the expression of Bax mRNA in the sciatic nerve cells （P<0.05， P<0.01）， while the low-dose MHGW group showed a decreasing trend in the expression of Bax mRNA. The expression of Caspase-12 mRNA in the sciatic nerve cells significantly decreased in all treatment groups （P<0.01）. ConclusionMHGW may improve and repair sciatic nerve damage in diabetes rats by inhibiting sciatic nerve cell apoptosis.
RESUMEN
ObjectiveTo investigate the protective effect of modified Huangqi Guizhi Wuwutang （MHGW） on endoplasmic reticulum stress in the sciatic nerve of diabetes rats based on the pathways of inositol-requiring enzyme 1α （IRE1α） and CCAAT/enhancer-binding protein homologous protein （CHOP）. MethodSixty rats were fed on a high-sugar and high-fat diet for six weeks， followed by intraperitoneal injection of streptozotocin at a dose of 35 mg·kg-1. Random blood glucose levels were measured three days later and rats with a sustained blood glucose level ≥ 16.7 mmol·L-1 were included in study （n=48）. The rats were randomly divided into a model group， an α-lipoic acid group （0.026 8 g·kg-1·d-1）， a high-dose MHGW group （2.5 g·kg-1·d-1）， and a low-dose MHGW group （1.25 g·kg-1·d-1）. Another 10 rats were assigned to the normal group. The intervention lasted for 16 weeks. After 16 weeks， the sciatic nerve structure of the rats in each group was observed under light microscopy using Luxol fast blue （LFB） staining. Transmission electron microscopy was used to observe the ultrastructure of the sciatic nerve. Chemiluminescence method was employed to measure the serum reactive oxygen species （ROS） levels. Western blot and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） were used to evaluate the expression of p-IRE1α protein， IRE1α mRNA， CHOP protein， and CHOP mRNA in the sciatic nerve of the rats. ResultCompared with the normal group， the model group showed elevated serum ROS levels （P<0.01）. In contrast， the serum ROS levels were significantly reduced in the treatment groups compared with those in the model group （P<0.01）. The sciatic nerve of the model group showed pathological changes compared with that in the normal group， while the treatment groups exhibited improvement in sciatic nerve pathology compared with the model group. The protein expression of p-IRE1α and CHOP in the sciatic nerve significantly increased in the model group as compared with that in the normal group （P<0.01）. However， the treatment groups showed a significant decrease in the protein expression of p-IRE1α and CHOP in the sciatic nerve compared with the model group （P<0.05， P<0.01）. Furthermore， compared with the normal group， the model group showed upregulated mRNA expression of IRE1α and CHOP in the sciatic nerve （P<0.01）， while the treatment groups exhibited a significant decrease in the mRNA expression of IRE1α and CHOP compared with the model group （P<0.01）. ConclusionMHGW can alleviate endoplasmic reticulum stress-induced cell apoptosis and improve the structure and function of the sciatic nerve in diabetes rats by inhibiting the expression of IRE1α/CHOP pathway-related proteins and mRNA， thereby preventing and treating peripheral neuropathy in diabetes.
RESUMEN
Abstract@#Defecation disorder is one of the most common complications after orthopedic surgery, which seriously affects patients' quality of life. Based on review of national and international publications pertaining to influencing factors and interventions of postoperative defecation disorders, this review analyzes the associations of orthopedic surgery-related factors with postoperative defecation disorders, and summarizes the common interventions for postoperative defecation disorders, including medication, physical therapy and daily life management, so as to provide insights into prevention and treatment of defecation disorders after orthopedic surgery.
