Jiedu Tongluo Tiaogan Prescription Protects Pancreatic β Cell by Targeting NLRP3 Inflammasome via TGR5/cAMP Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the intervention effect of Jiedu Tongluo Tiaogan prescription （JTTP） in protecting pancreatic β cells by targeting the bile acid Takeda G protein-coupled receptor 5 （TGR5）/cyclic adenosine monophosphate （cAMP） signaling pathway against NOD-like receptor protein 3 （NLRP3） inflammasome. MethodThirty-two male SPF-grade db/db mice were randomly divided into the model group， low-dose JTTP group （3.6 g·kg-1）， high-dose JTTP group （7.2 g·kg-1）， and metformin group （0.2 g·kg-1）. Eight db/m mice were assigned to the blank control group. The mice were treated with drugs for 8 weeks， and fasting blood glucose （FBG） was measured every 2 weeks. Oral glucose tolerance tests （OGTT） were conducted after the last administration. Enzyme-linked immunosorbent assay （ELISA） was performed to detect fasting insulin （FINS）， and the homeostasis model assessment of β-cell function （HOMA-β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， and IL-1β levels were calculated. Hematoxylin-eosin （HE） staining was used to observe pathological changes in mouse pancreatic tissue. Immunofluorescence was performed to detect insulin expression in mouse pancreatic tissue. Western blot and real-time quantitative polymerase chain reaction （Real-time PCR） were used to detect the expression of proteins and mRNAs of key targets in the TGR5/cAMP signaling pathway and NLRP3 inflammasome. ResultCompared with blank group， FBG， OGTT， FINS， IL-6， TNF-α and IL-1β in model group were significantly increased （P<0.01）. Compared with model group， after 6 weeks of drug treatment， FBG level in JTTP group and metformin group decreased significantly （P<0.01）. The results of OGTT experiment showed that compared with model group， the blood glucose levels of mice in each administration group were decreased at all time points （P<0.05， P<0.01）， and the levels of FINS， TNF-α and IL-6 in JTTP dose groups and metformin group were significantly decreased. The level of IL-1β in JTTP high-dose group and metformin group was significantly decreased （P<0.01）. Pancreatic pathology showed that the islets in the model group were irregular in shape， uneven in distribution， and showed signs of atrophy. The prognosis of JTTP was that the cell count increased and the boundary was clearer. Immunofluorescence results showed that the islet cells in the blank group were arranged in an orderly and full shape with appropriate insulin secretion， while the islet cells in model group were distorted in shape， atrophy in structure and less insulin secretion. The insulin content of mice in JTTP and metformin group was significantly increased. Compared with blank group， mRNA expressions of NLRP3， apoptosis-related spot-like protein （ASC） and Caspase-1 in pancreatic tissues of model group were significantly increased （P<0.01）. Compared with model group， JTTP high-dose group and metformin group promoted the up-regulation of TGR5 and cAMP mRNA， and down-regulated the mRNA expressions of NLRP3， ASC and Caspase-1 （P<0.05， P<0.01）. Compared with blank group， the expression of TGR5 protein in model group was significantly decreased （P<0.01）. Compared with model group， TGR5 protein in JTTP high-dose group and metformin group was significantly increased （P<0.01）.

Study on Variation Trend of Pre-treatment Blood Human Chorionic Gonadotropin in Predicting Efficacy of Tubal Pregnancy Treated by Drug Therapy / 广州中医药大学学报

Objective To investigate the role of variation trend of pre-treatment blood beta human chorionic gonadotropin(β-HCG)in predicting the efficacy of tubal pregnancy(TP)treated by drug therapy.Methods Clinical data of 380 TP patients treated by drug therapy at the First Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2017 to June 2022 were collected.The patients were divided into 271 cases in the pure Chinese medicine(CM)treatment group(shortened as pure CM group)and 109 cases in the combination of Chinese medicine and western medicine group(shortened as combination group)according to the therapy.The relevant factors that may affect the outcomes of the therapy were analyzed,and logistic regression analysis was used for the control of confounding factors.The influences of pre-treatment β-HCG on the outcomes of TP treated by various therapies were investigated,and the value of variation trend of pre-treatment β-HCG in predicting the efficacy of TP treated by drug therapy was assessed using the receiver operating characteristic curve(ROC curve).Results(1)The results of univariate analysis showed that the initial value of blood β-HCG,the variation trend of β-HCG and the difference value of β-HCG detected for 2 times before treatment were correlated with the treatment outcomes in the pure CM group and the combination group,and the differences were all statistically significant(P＜0.05 or P＜0.01).(2)The results of multivariate regression analysis showed that in the pure CM group,the blood β-HCG values and the variation trend of β-HCG detected for 2 times before treatment were correlated with the treatment outcomes,and the differences were all statistically significant(P＜0.05 or P＜0.01);in the combination group,the menopausal time and blood β-HCG value detected at the second time before treatment were correlated with the treatment outcomes,and the differences were all statistically significant(P＜0.05).(3)After controlling for the confounding factors,the variation trend of pre-treatment β-HCG in the pure CM group was correlated with the treatment outcomes,and the difference was statistically significant(OR=3.35,95%CI being 1.69-6.65,P = 0.001).However,the variation trend of pre-treatment β-HCG in the combination group did not affect the treatment outcomes,and the difference was not statistically significant(P＞0.05).(4)The ROC curve analysis showed that the area under the curve(AUC)in the pure CM group was 0.74,the cutoff value was-0.14,the sensitivity was 71.3%and the specificity was 67.8%.The AUC in the combination group was 0.67,the cutoff value was 0.10,the sensitivity was 73.6%and the specificity was 60.7%.Conclusion The variation trend of pre-treatment blood β-HCG can effectively predict the efficacy of Chinese medicine for the treatment of TP,but has no value for predicting the efficacy of the combination of Chinese medicine and western medicine in treating TP.The variation value of pre-treatment blood β-HCG can be used as a valuable reference indicator for the early prediction of the outcomes of TP treated by drug therapy.

Theoretical Validation of the Identification of Therapeutic Dominant Stages of Traditional Chinese Medicine Based on Subdivision Model of Disease Course:Taking Premature Ovarian Failure for Example / 广州中医药大学学报

Objective To explore the feasibility and operability in identifying the therapeutic dominant stages of traditional Chinese medicine(TCM)based on subdivision model of disease course.Methods The hierarchical Bayesian model was used to differentiate the disease course of 125 cases of premature ovarian failure(POF),and the disease course of POF were divided into the occult stage,diminished ovarian reserve(DOR)stage,premature ovarian insufficiency(POI)stage,and POF stage.An then the paired sample t-test,Pearson correlation analysis and expert in-depth interview were used for the analysis of the therapeutic effects of TCM for POF at various stages.Results(1)Compared with POF stage,DOR and POI stages were frequently intervened by Chinese patent medicine.(2)In DOR(complicated with POI)stage and POF stage,there was significant difference between the degree of TCM intervention and the therapeutic effect(t =-3.70,P＜0.001).(3)The degree of TCM intervention was positively correlated with treatment outcomes in the DOR stage(r = 0.679,P＜0.001),so did in the POF stage(r = 0.432,P＜0.001),but the correlation in the POF stage was slightly lower than that in the DOR stage.(4)The results of in-depth interviews with experts of TCM gynecology showed that in the concealed phase of POF,the prognosis would be most favorable if TCM regulation and intervention were performed.In the DOR stage and POI stage,treatment with Chinese medicine prescriptions usually brought about better curative effect and prognosis.For the patients at POF stage,the therapeutic effect of TCM depended on the patients'compliance and the treatment course,and the effect was relatively not as good as that of the previous stages.Conclusion In the DOR stage and POF stage,the higher the degree of TCM intervention,the better the prognosis will be achieved for the patients treated with western medicine.In the POF stage,the efficacy of TCM intervention is reduced to a certain extent compared with the DOR stage.The results indicated that it is feasible and operable to identify the TCM therapeutic dominant stages based on the subdivision model of disease course.

3D printing process of gelatin/oxidized nanocellulose skin scaffold with high elastic modulus and high porosity / 中国组织工程研究

BACKGROUND:In the treatment of skin trauma with active repair,tissue engineering techniques are needed to generate new tissue to replace necrotic tissue.Skin scaffolds have a good application prospect in the field of wound repair.Skin scaffolds need to present three-dimensional porous structures with certain mechanical strength to meet the needs of cell proliferation and division.However,the mechanical strength of the currently used gelatin-based biomaterials is weak and cannot meet the requirements of the use of skin scaffolds. OBJECTIVE:To study the 3D printing process used in the preparation of tissue engineering skin scaffolds by gelatin/oxidized nanocellulose composites,and focus on the relationship between the porosity and mechanical strength of the scaffolds prepared under different process parameters. METHODS:Oxidized nanocellulose whiskers at 10%concentration were extracted from Humulus scandens and then compounded with 5%gelatin to obtain gelatin/oxidized nanocellulose composites.The elastic modulus of gelatin and gelatin/oxidized nanocellulose composite was determined.Skin scaffolds were prepared by 3D printing extrusion molding using gelatin/oxidized nanocellulose composite as the base material.Mechanical and rheological properties of the composite were tested to determine extrusion molding parameters(filling gap 1.5-2.5 mm,uniform distribution of 0.1 mm;air pressure of 160-200 kPa),and the skin scaffold with a three-dimensional porous structure was prepared.The compressive performance of the skin scaffold was tested and compared with the finite element analysis results.The relationship between the filling gap and the porosity and mechanical strength of the scaffold was demonstrated. RESULTS AND CONCLUSION:(1)The elastic modulus of 5%gelatin was increased by 8.84 times by adding 10%oxidized nanocellulose whisker.A gel filament with a diameter of 1 mm was obtained by extrusion at the air pressure of 160 kPa.When the filling gap increased from 1.5 mm to 2.5 mm,the theoretical porosity of the scaffold increased from 33%to 60%,but the compressive strength decreased from 230 000 Pa to 95 000 Pa.(2)These findings showed that the skin scaffold with theoretical porosity of 50%and elastic modulus of 160 000 Pa was prepared by using 2 mm filling gap.The scaffold had a clear three-dimensional porous structure.

Objective To compare the difference of peripheral blood adiponectin and CD4+T cell subsets between patients with a-cute gouty arthritis and healthy controls,to explore the correlation between adiponectin and serum uric acid,disease activity,CT4+T cell subsets and some cytokines in patients with gout.Methods The clinical data(including general data,neutrophils,erythrocyte sedimen-tation rate,C-reactive protein,blood uric acid,CT4+T cell subsets and some cytokines)of acute gout group(n=90)and healthy con-trol group(n=72)were collected.The level of adiponectin in peripheral blood of two groups were detected,and the differences of adi-ponectin and CD4+T cell subsets between the two groups were compared;the correlation between adiponectin and clinical data was ana-lyzed.Results The levels of serum adiponectin in the acute gout group were significantly lower than those in the healthy control group(P＜0.001),and the levels of Th2,Thl7,Th17/Treg were significantly higher than those in the healthy control group(P＜0.05),while the levels of Treg and Th1/Th2 were significantly lower than those in the healthy control group(P＜0.05).In the acute gout group,adiponectin was negatively correlated with neutrophil,erythrocyte sedimentation rate and C-reactive proten(r=-0.244,P＜0.05;r=-0.311,P＜0.05;r=-0.506,P＜0.001),there was no correlation with serum uric acid.In acute gout group,adiponectin was posi-tively correlated with Th1 and Th1/Th2(r=0.252,P＜0.05;r=0.218,P＜0.05).In acute gout group,adiponectin in peripheral blood was positively correlated with interleukin-2(IL-2),interleukin-4(IL-4)and interleukin-10(IL-10)(r=0.323,P＜0.05;r=0.377,P＜0.05;r=0.359,P＜0.05).There was a negative correlation between interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)(r=-0.265,P＜0.05;r=-0.299,P＜0.05).Multiple linear regression analysis showed that adiponectin in the acute gout group was negatively correlated with erythrocyte sedimentation rate,C-reactive protein,IL-6 and TNF-α(BESR=-12.541,P=0.003;BCRP=-8.256,P=0.024;BIL-6=-15.907,P=0.037;BTNF-α=-79.770,P=0.040),but positively correlated with Th1(BTh1=2.959,P=0.006).Conclusion The levels of adiponectin in the peripheral blood of patients with acute gouty arthritis were decreased,the levels of Th2 and Th17 were increased,and the levels of Treg were decreased.The decrease of adi-ponectin was related to the immunological disorder and inflammation in the patients with acute gouty arthritis.

Progress of important clinical research of breast cancer in China in 2023 / 中国癌症杂志

Breast cancer is the most prevalent malignant tumor among women globally,posing a serious threat to women's health.With the establishment of staging and typing principles for breast cancer diagnosis and treatment,and the development and application of novel antitumor drugs,the survival and quality of life of breast cancer patients have been continuously improving.In China,the large base of breast cancer patients possesses unique incidence characteristics,necessitating ongoing exploration of more appropriate treatment strategies;the volume and level of clinical research are also continuously advancing.In 2023,significant clinical research results were reported for different subtypes of breast cancer.In surgical treatment,clinical trials on targeted axillary lymph node dissection and the establishment of a predictive model BRCA-CRisk for contralateral breast cancer risk provide more evidence for de-escalation in surgical treatment.In the area of human epidermal growth factor receptor 2(HER2)-positive breast cancer,pyrotinib has shown significant efficacy in advanced breast cancer treatment.In triple-negative breast cancer,precision subtype treatment and immunotherapy continue to improve patient survival.For hormone receptor-positive breast cancer,significant research results were obtained in exempting low-risk patients from chemotherapy and exploring alternative options after resistance to endocrine therapy.In the aspect of BRCA mutations,BGB-290-201 further confirmed the therapeutic efficacy and safety of poly(ADP-ribose)polymerase(PARP)inhibitors for the Chinese population.For advanced HER2-negative patients carrying germline BRCA(gBRCA)1/2 mutations,pamiparib will be an ideal treatment choice.This article reviews the important clinical research in the field of breast cancer in China in 2023,summarizes key results,and aims to provide reference ideas for future clinical research.

Research progress on factors affecting biomechanical strength of pedicle screw internal fixation / 中华骨科杂志

The pedicle screw internal fixation system plays a crucial role in spinal surgery, with the advantage of enhancing spinal stability. However, potential complications such as internal fixation loosening and screw pullout still exist clinically. Currently, pullout of strength is commonly used to evaluate the short-term biomechanical properties of internal fixation, fatigue test is performed to evaluate the long-term biomechanical properties of internal fixation, and torque is used to evaluate the interaction between screws and spinal bone. Factors that influence the biomechanical properties of pedicle screws include spine-related factors (bone density) and screw-related factors (screw size, screw design, and screw augmentation materials). In bones with high bone density, pullout of strength is significantly increased, and fixation strength can also be improved by increasing screw diameter and length, improving screw design, and using screw augmentation materials. Biomechanical research on pedicle screw internal fixation provides key information for achieving individualized and functional optimal channel selection. Designing screw channels with optimal fixation strength is expected to reduce the risk of screw loosening and the occurrence of surgical complications, and improve surgical effects.

Study on the efficacy of beat chemotherapy in treating non-small cell lung cancer / 中华老年医学杂志

Objective:To assess the effectiveness and safety of beat chemotherapy in treating non-small cell lung cancer, and to investigate its anti-tumor molecular mechanism.Methods:In this study, we developed a subcutaneous tumor model of lung cancer in mice.The mice were subsequently divided into two groups: the beat chemotherapy group and the placebo group(negative control group).Throughout the treatment period, we monitored the changes in body weight and tumor size of the mice.At the conclusion of the treatment, we collected blood samples from the mice to conduct blood routine and biochemical examinations.Furthermore, we obtained tumor tissues from the mice to perform immunohistochemical staining and sequencing of the transcriptome.Results:The study found that beat chemotherapy could effectively delay the growth of lung cancer.The tumor tissues in the beat chemotherapy group were significantly smaller compared to the placebo group.The results of routine blood and blood biochemistry tests showed that the levels of red blood cells(RBCs), white blood cells(WBCs), alanine aminotransferase(ALT), aspartate aminotransferase(AST)and blood creatinine(Scr)were similar between the placebo group and the beat chemotherapy group.The values for RBCs, WBCs, ALT, AST and Scr in the placebo group were(6.97 ± 0.41)× 10 12/L, (13.26 ± 0.29)× 10 9/L, (33.33 ± 2.51)U/L, (235.33 ± 57.62)U/L and(20.67 ± 2.08)μmol/L, respectively.The corresponding values in the beat chemotherapy group were(6.87 ± 0.66)× 10 12/L, (12.59 ± 2.27)× 10 9/L, (38.67 ± 3.79)U/L, (225.33 ± 6.81)U/L and(20.33 ± 3.79)μmol/L.Statistical analysis showed no significant differences between the two groups( t=0.509, 0.209, 2.032, 0.299, 0.134, P=0.638, 0.845, 0.112, 0.780, 0.900).Furthermore, there were no signs of inflammatory infiltration or pathological changes in the liver, kidney, spleen, and lung tissues of the mice.Transcriptome analysis identified 68 differentially expressed genes, which were mainly associated with signal transduction and immunity.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis revealed the involvement of several signaling pathways, including the transforming growth factor β(TGF-β)signaling pathway, the interleukin-17(IL-17)signaling pathway, and the tumor necrosis factor(TNF)signaling pathway. Conclusions:The use of chemotherapy has been proven to be safe and effective in treating non-small cell lung cancer.It primarily functions by regulating tumor growth through various signaling pathways, including the TGF-β signaling pathway, IL-17 signaling pathway, and TNF.

Herbal Textual Research on Olibanum in Famous Classical Formulas / 中国实验方剂学杂志

By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.

Clinical and pathological analysis of 345 cases of vulvar lichen sclerosus and a preliminary study on the frequency of maintenance treatment / 中华妇产科杂志

Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

Effect of cognitively engaging physical activity on developing executive function of children and adolescents: a systematic review based on ICF / 中国康复理论与实践

ObjectiveTo systematically review the intervention effect of cognitively engaging physical activity (CEPA) on executive function of children and adolescents. MethodsLiteratures in Chinese and English were retrieved from databases of Web of Science, PubMed, Medline, EBSCO and CNKI, from the establishment to November 30th, 2023. According to the inclusion and exclusion criteria, the literatures that met the requirements were screened, and their quality was evaluated and systematically reviewed. ResultsA total of 15 literatures were included, published between 2014 and 2023, from eight countries, involving 1 806 subjects aged four to 16 years. The average score of PEDro scale was 6.6. The intensity of the CEPA intervention ranged from 64% to 93% HRmax, the duration of a single session ranged from ten to 60 minutes, and the frequency of the intervention was two to five sessions a week, for four to 24 weeks. Specific forms of CEPA included football, basketball and floorball combined with cognitive tasks; running, jumping, squatting, sitting, spinning and balancing combined with cognitive tasks; and exergaming combined with cognitive tasks. Eleven researches showed positive effects of CEPA intervention on at least one component of executive function. However, six of the seven researches involving working memory failed to verify the positive effects. Twelve researches compared the intervention effects of CEPA and rutine exercise or regular physical education classes, and nine researches found that CEPA was more effective on executive function. ConclusionThe CEPA is effective on the executive function of children and adolescents, specifically on cognitive flexibility; it shows inconsistent effects on inhibitory control, and its effect on working memory has not been verified. The intervention types of CEPA are divided into ball games combined with cognitive tasks, basic motor skills training combined with cognitive tasks, and exergaming combined with cognitive tasks.

Short-term efficacy of surgical treatment for multiple pulmonary nodules: A retrospective study in a single center / 中国胸心血管外科临床杂志

@#Objective To summarize and analyze the clinical diagnosis, surgical treatment and prognosis of multiple pulmonary nodules (MPNs). Methods The clinical data of lung cancer patients who received surgical treatment in our hospital from 2018 to 2020 were collected. The short-term efficacy of surgical treatment for MPNs was analyzed. Results A total of 97 patients were enrolled, including 30 males and 67 females with an average age of 56.1±10.0 years at onset ill. There were 62 patients with double lesions, 22 patients with three lesions, 4 patients with four lesions, and 9 patients with more than four lesions. A total of 213 lesions were surgically treated, including 88 pure ground-glass nodules, 81 partially solid nodules, and 7 solid nodules. There were 87 simultaneous surgeries and 10 staged surgeries, with an average operation interval of 5.2 months. The pathological combination type included adenocarcinoma-adenocarcinoma in 96 (99.0%) patients, squamous cell carcinoma-squamous cell carcinoma in 1 (1.0%) patient, and no lymph node metastasis was found. The 2-year disease-free survival (DFS) rate was 92.1%, and the overall survival (OS) rate was 100.0%. Univariate analysis showed that high-risk lesion size>2 cm (P=0.316), residual lesions (P=0.782) and pathological combination type (P=0.913) had statistical effect on the 2-year DFS rate. Conclusion MPNs are mainly diagnosed with multiple primary lung cancers, and the pathological combination is mostly adenocarcinoma-adenocarcinoma combination. Imaging examination is of great help to the surgical approach selection, diagnosis and differential diagnosis of MPNs. During the operation, maximal preservation of lung function and complete resection of high-risk nodules should be taken as the principle, and the prognosis is satisfactory.

Clinical Efficacy of Fuzheng Huaji Longbi Decoction in Treating Benign Prostatic Hyperplasia with Syndrome of Healthy Qi Deficiency and Blood Stasis / 中国实验方剂学杂志

ObjectiveTo explore the clinical efficacy and safety of Fuzheng Huaji Longbi decoction in treating benign prostatic hyperplasia （BPH） in the patients with the syndrome of healthy Qi deficiency and blood stasis. MethodA total of 94 BPH patients were randomized into control and observation groups， with 47 patients in each group. The control group was treated with doxazosin mesylate sustained-release tablets， and the observation group with Fuzheng Huaji Longbi decoction on the basis of the therapy in the control group. After eight weeks， the international prostate symptom score （IPSS）， quality of life （QOL） score， residual urine volume （RUV）， maximum urinary flow rate （Qmax）， TCM syndrome score， TCM symptom score， electrocardiogram， and liver and kidney function were determined to evaluate the clinical efficacy and safety of the two groups. ResultAfter 8 weeks of treatment， the total response rate in the control group was 63.64% （28/44）， which was lower than that （84.44%， 38/45） in the observation group （χ2=5.026， P<0.05）. The clinical efficacy in the observation group was higher than that in the control group （Z=-2.17， P=0.030）. The treatment in both groups decreased the IPSS， QOL score， RUV， and TCM syndrome scores and increased the Qmax （P<0.05）. Moreover， the observation group had lower IPSS， QOL score， RUV， and TCM syndrome score （P<0.05） and higher Qmax than the control group after treatment （P<0.05）. The treatment in the observation group decreased all the TCM symptom scores （P<0.05）， while that in the control group only decreased the frequency of urination at night and the scores of dysuria， weak urine stream， and post-urinary drainage （P<0.05）. After treatment， the observation group had lower frequency of urination at night and lower scores of mental fatigue， cold limbs， lower abdominal discomfort， and loose stool than the control group （P<0.05）. No adverse events associated with the administration of Fuzheng Huaji Longbi decoction were observed during the treatment period. ConclusionFuzheng Huaji Longbi decoction is effective in treating BPH in the patients with the syndrome of healthy qi deficiency and blood stasis. It can relieve the clinical symptoms and improve the quality of life， being a safe and reliable choice for clinical application.

Study on the potential allergen and mechanism of pseudo-allergic reactions induced by combined using of Reduning injection and penicillin G injection based on metabolomics and bioinformatics / 药学学报

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

Effect of Liuwei Dihuang Tang on ferroptosis pathway in retinal tissue of aging model rats / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the effects of Liuwei Dihuang Tang on the expression levels of ferritin, recombinant solute carrier family 7 member 11(SLC7A11), glutathione(GSH), and glutathione peroxidase 4(GPX4)in retinal of aging model rats.METHODS: A total of 45 SD rats were randomly divided into a blank group, a model group, and a traditional Chinese medicine(TCM)group, with 15 rats in each group. The blank group was intraperitoneally injected with physiological saline, while the model group and TCM group were intraperitoneally injected with D-galactose [500 mg/(kg·d)]. At the same time, the TCM group was orally administered with Liuwei Dihuang Tang [6.75 g/(kg·d)], while the blank group and model group were orally administered with equal volume of physiological saline for 8 consecutive wk. The expression levels of ferritin, SLC7A11, GSH, and GPX4 in the retinal tissues of rats in each group were detected.RESULTS: The expression of ferritin in the retinal tissue of the model group was increased compared to the blank group(P&#x003C;0.05), while the expression of GSH, SLC7A11, and GPX4 was reduced(P&#x003C;0.05). The expression of GSH, SLC7A11, and GPX4 in the retina tissue of rats in the TCM group was higher than that in the model group(P&#x003C;0.05).CONCLUSIONS: Liuwei Dihuang Tang may exert a delaying effect on retinal aging by regulating the ferroptosis pathway.
