Mechanism of Liuwei Dihuang Pills in treatment of mice with diminished ovarian reserve based on proteomics / 中国中药杂志

This study aims to investigate the efficacy and possible mechanism of Liuwei Dihuang Pills in the treatment of diminished ovarian reserve(DOR) by using proteomic techniques. Firstly, cyclophosphamide(60 mg·kg~(-1)) combined with busulfan(6 mg·kg~(-1)) was injected intraperitoneally to establish the mouse model of DOR. After drug injection, the mice were continuously observed and the success of modeling was evaluated by the disturbance of the estrous cycle. After successful modeling, the mice were administrated with the suspension of Liuwei Dihuang Pills by gavage for 28 days. At the end of the gavage, four female mice were selected and caged together with males at a ratio of 2∶1 for the determination of the pregnancy rate. Blood and ovary samples were collected from the remaining mice on the next day after the end of gavage. Hematoxylin-eosin(HE) staining and transmission electron microscopy(TEM) were then employed to observe the morphological and ultrastructural changes in the ovaries. The serum levels of hormones and oxidation indicators were measured by enzyme-linked immunosorbent assay. Quantitative proteomics techniques were used to compare the ovarian protein expression before and after modeling and before and after the intervention with Liuwei Dihuang Pills. The results showed that Liuwei Dihuang Pills regulated the estrous cycle of DOR mice, elevated the serum levels of hormones and anti-oxidation indicators, promoted follicle development, protected the mitochondrial morphology of ovarian granulosa cells, and increased the litter size and survival of DOR mice. Furthermore, Liuwei Dihuang Pills negatively regulated the expression of 12 differentially expressed proteins associated with DOR, which were mainly involved in lipid catabolism, inflammatory response, immune regulation, and coenzyme biosynthesis. These differentially expressed proteins were significantly enriched in sphingolipid metabolism, arachidonic acid metabolism, ribosomes, ferroptosis, and cGMP-PKG signaling pathway. In summary, the occurrence of DOR and the treatment of DOR with Liuwei Dihuang Pills are associated with multiple biological pathways, mainly including oxidative stress response, inflammatory response, and immune regulation. "Mitochondria-oxidative stress-apoptosis" is the key to the treatment of DOR by Liuwei Dihuang Pills. YY1 and CYP4F3 may be the key upstream targets that trigger mitochondrial dysfunction and ROS accumulation, and the metabolism of arachidonic acid is the main signaling pathway of drug action.

Observational study on perioperative outcomes of pelvic exenteration / 中华胃肠外科杂志

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

Research progress on structure, function and disease correlation of solute carrier family 4 / 生理学报

The solute carrier family 4 (SLC4) includes 10 members (SLC4A1-5, SLC4A7-11), which are expressed in multiple tissues in the human body. The SLC4 family members differ in their substrate dependence, charge transport stoichiometry and tissue expression. Their common function is responsible for the transmembrane exchange of multiple ions, which is involved in many important physiological processes, such as erythrocyte CO2 transport and the regulation of cell volume and intracellular pH. In recent years, many studies have focused on the role of SLC4 family members in the occurrence of human diseases. When SLC4 family members have gene mutations, a series of functional disorders will occur in the body, leading to the occurrence of some diseases. This review summarizes the recent progress about the structures, functions and disease correlation of SLC4 members, in order to provide clues for the prevention and treatment of related human diseases.

Adverse outcomes of hypertensive disorders of pregnancy: development and validation of a predictive model / 中华围产医学杂志

Objective:To develop and validate a predictive model for adverse outcomes in women with hypertensive disorders of pregnancy (HDP).Methods:We retrospectively analyzed the clinical data of patients diagnosed with HDP and delivered at the First Affiliated Hospital of Soochow University or Sichuan Provincial Maternity and Child Health Care Hospital between May 1, 2011, and April 30, 2019. These patients were categorized as the adverse outcome group or the control group with adverse outcomes within 48 h after admission. Univariate analysis, least absolute shrinkage, selection operator (LASSO), and multivariable logistic regression were employed to analyze factors influencing the adverse outcomes and develop a predictive model. The receiver operating characteristic (ROC) curve and calibration plot was used to assess the predictive performance. Bootstrapping was used for the internal validation and the retrospective dataset of patients with HDP from the First Affiliated Hospital of Soochow University from May 1, 2019, to April 30, 2020, for the external validation. A graphic nomogram was created through R software based on the model.Results:(1) Of the 2 978 HDP patients who were included in the development set, 356 were in the adverse outcome group, accounting for 12.0%; of the 233 patients who were included in the external validation set, 40 presented with adverse outcomes within 48 h after admission, accounting for 17.2%. (2) Nine optimal predictors were identified based on the LASSO regression analysis and multivariable logistic regression, consisting of gestational age on admission, routine prenatal care, number of symptoms, mean arterial pressure, platelet count, fibrinogen, albumin, serum urea, and serum creatinine, based on which the logistic predictive model was established. (3) The ROC curve for this predictive model achieved an area under the curve (AUC) of 0.878 (95% CI: 0.858-0.897), and the ideal cut-off value for predicted probability was 0.136, with a sensitivity of 0.778 (95% CI: 0.731-0.820) and specificity of 0.848(95% CI: 0.834-0.862). The model was well-calibrated as the Hosmer-Lemeshow test showed that P>0.05. The calibration plot of the model had a slope of 1 and an intercept of 0. (4) The model showed good consistency in the internal validation and had an AUC of 0.872 (95% CI: 0.807-0.937) in the external validation. The Hosmer-Lemeshow test showed that the P value was >0.05, and the calibration slope was 1.001. (5) A nomogram was constructed for convenient clinical use. Conclusion:A relatively accurate prediction model for adverse outcomes in HDP patients was established, which could be used as a valuable quantitative tool for assessing HDP-related complications.

From April 2018 to November 2019, 21 cases of Irvine-Gass syndrome patients with 24 eyes were included in the study. Among them, there were 11 females with 12 eyes and 10 males with 12 eyes; the average age was 54.5±10.1 years. All the affected eyes underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination. BCVA was performed using a standard logarithmic visual acuity chart, and the results were converted into the logarithmic minimum angle of resolution (logMAR) visual acuity when recording. The frequency domain OCT instrument was used to measure the foveal retinal thickness (CMT) and the retinal volume (MRV) of the macular area with a diameter of 1, 6 mm. All the affected eyes were treated with a micropulse laser under the threshold of 577 nm, with a spot diameter of 200 μm, an exposure time of 200 ms, a power of 400 mW, and a 5% duty cycle. The treatment scope was in the upper and lower vascular arches of the macula, covering the entire macula (including the fovea). One or 3 months after treatment, the eyes with macular edema were treated twice with micropulse laser, the method was the same as before. 1, 3, and 6 months after the treatment, the same equipment and methods as before the treatment were used for related inspections. The changes of BCVA, CMT, MRV and the occurrence of complications in the affected eye were observed.Results:The average logMAR BCVA of the eyes before treatment and 1, 3, and 6 months after treatment were 0.440±0.320, 0.333±0.286, 0.250±0.245, 0.166±0.184, and the average CMT were 395.88±79.21, 349.17±78.07, 317.67±53.72, 285.29±37.03 μm, respectively; the average MRV of diameter 1, 6 mm were 0.310±0.063, 0.275±0.060, 0.245±0.035, 0.221±0.219 mm 3 and 9.866±0.846, 9.494±1.002, 9.005±0.885, 8.190±0.850 mm 3. Compared with before treatment, the BCVA of the eyes at 1, 3, and 6 months after treatment was significantly increased ( t=5.060, 5.564, 6.466), and CMT was significantly decreased ( t=4.854, 5.777, 7.349), and the differences were statistically significant ( P<0.01); the average MRV of diameters 1, 6 mm decreased significantly, and the difference was statistically significant (1 mm diameter: t=4.527, 5.394, 7.380; P<0.01; diameter 6 mm: t=4.577, 7.980, 11.209; P<0.01).

Individualized treatment for allergic rhinitis based on key nasal clinical manifestations combined with histamine and leukotriene D4 levels / Tratamento individualizado para a rinite alérgica baseado nas principais manifestações clínicas nasais e dos níveis de histamina e leucotrieno D4

Abstract Introduction The types of allergic rhinitis are roughly classified based on the causative antigens, disease types, predilection time, and symptom severity. Objective To examine the clinical typing and individualized treatment approach for allergic rhinitis and to determine the optimal treatment method for this disease using various drug combination therapies. Methods A total of 108 participants with allergic rhinitis were divided into three groups based on symptoms. Subsequently, each group was further categorized into four subgroups based on the medications received. The efficacy of the treatments was evaluated using the visual analog scale VAS scores of the total and individual nasal symptoms, decline index of the symptom score, histamine and leukotriene levels, and mRNA and protein expression levels of histamine 1 and cysteinyl leukotriene 1 receptors. Results Loratadine + mometasone furoate and loratadine + mometasone furoate + montelukast significantly improved the sneezing symptom and reduced the histamine levels compared with the other combination therapies (p < 0.05). Meanwhile, montelukast + mometasone furoate and montelukast + mometasone furoate + loratadine considerably improved the nasal obstruction symptom and decreased the leukotriene D4 levels compared with the other combination therapies (p < 0.05). Conclusion Clinical symptom evaluation combined with experimental detection of histamine and leukotriene levels can be an objective and accurate method to clinically classify the allergic rhinitis types. Furthermore, individualized treatment based on allergic rhinitis classification can result in a good treatment efficacy.

Resumo Introdução A rinite alérgica é basicamente classificada de acordo com os antígenos causadores, tipos de doença, peridiocidade e gravidade dos sintomas. Objetivo Avaliar os tipos clínicos e a abordagem terapêutica individualizada para cada tipo de rinite alérgica e determinar o método de tratamento ideal utilizando várias terapias de combinação de fármacos. Método Um total de 108 participantes com rinite alérgica foram divididos em três grupos com base nos sintomas. Posteriormente, cada grupo foi subsequentemente categorizado em quatro subgrupos com base nos medicamentos recebidos. A eficácia dos tratamentos foi avaliada utilizando os escores da escala visual analógica EVA dos sintomas nasais totais e individualmente, índice de declínio do escore de sintomas, níveis de histamina e leucotrienos e níveis de expressão de mRNA e proteína dos receptores de histamina 1 e cisteinil-leucotrieno 1. Resultados As associações entre loratadina + furoato de mometasona, assim como a de loratadina + furoato de mometasona + montelucaste melhoraram significativamente o sintoma de espirros e reduziram os níveis de histamina em comparação às outras terapias combinadas (p < 0,05). Por outro lado, a associação montelucaste + furoato de mometasona, assim como a associação montelucaste + furoato de mometasone + loratadina melhoraram consideravelmente o sintoma de obstrução nasal e diminuíram os níveis de leucotrieno D4 em comparação com as outras combinações (p < 0,05). Conclusão A avaliação clínica dos sintomas combinada com a detecção experimental dos níveis de histamina e leucotrieno pode ser um método objetivo e preciso para classificar clinicamente os tipos de rinite alérgica. Além disso, o tratamento individualizado baseado na classificação da rinite alérgica pode resultar no aumento da eficácia do tratamento.

Besides electroacupuncture (EA) applied to Baihui (GV 20) and Yintang (GV 29) in all of the three groups, acupuncture was added at Shenmai (BL 62) and Zhaohai (KI 6), Shenmen (HT 7) and Sanyinjiao (SP 6) as well as back-@*RESULTS@#After treatment, the score of each of 6 factors, named sleep quality, sleep latency, sleep time, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score of PSQI scale were all reduced as compared with the scores before treatment in the patients of each group (@*CONCLUSION@#All of the three acupuncture combinations, named

Antithrombotic therapy after iliac vein stenting / 浙江大学学报·医学版

Stenting for iliac vein stenosis or compression has become a common therapeutic approach in recent years. The antithrombotic therapy after the stent deployment, however, reaches no consensus. Medications strategies and patients' prognoses differ in non-thrombotic, acute thrombotic and chronic thrombotic these three circumstances. Non-thrombotic patients usually possess satisfactory stent patency whatever antithrombotic therapy is used. Anticoagulant is the basic medication for acute thrombotic patients, benefits from additional antiplatelet drug remains to be clarified. In terms of chronic thrombotic patients, their prognoses are unsatisfactory under all antithrombotic therapies. In this review, we outlined the recent progress of antithrombotic therapy after iliac vein stenting, aiming to provide feasible medication plans for each circumstance.

Decitabine combined with arsenious acid in the treatment of patients with higher-risk myelodysplastic syndromes and chronic myelomonocytic leukemia / 中国实用内科杂志

OBJECTIVE: To evaluate the clinical efficacy of decitabine combined with arsenious acid in the treatment of patients with higher-risk myelodysplastic syndromes(MDS) and chronic myelomonocytic leukemia(CMML). METHODS: Totally 39 patients with MDS and 8 patients with CMML received the treatment of decitabine and arsenious acid from April 2016 to December 2018. Decitabine [20 mg/(m~2·d)] and arsenious acid [0.15 mg/(m~2·d)] were administered intravenously for 5 consecutive days every 4-6 weeks. Patients who achieved complete or partial remission entered into the consolidation cycle. Efficacy and influencing factor were analyzed. RESULTS: Clinical response were observed in 31 patients after a median of 2 courses(ranging 1-12) of treatment. The overall response rate(ORR) was 66.0%. The median duration of response was 16 weeks(ranging 2-52 weeks). There were 8 cases(17.0%) of complete remission(CR), 10 cases(21.3%) of partial remission(PR),12 cases(25.5%) of hematological improvement(HI), 1 case(2.1%) of marrow complete remission(mCR), 8 cases(17.0%) of stable disease(SD), and 1 case(2.1%) of progressive disease(PD). By next generation sequencing, 25 genes mutated with 70 times in 33 cases. The mutation frequency of epigenetic regulators(57.6%) was higher than splicing factors(33.5%), transcription factors and kinase signaling(54.5%),and TP53(21.2%)(P<0.01). There was no significant difference in response rates among these patients(47.4%, 54.5%, 50.0% and85.7%, P=0.977). Gene mutation frequency(VAF) of patients who responded to the regimen declined significantly(16.67% vs. 10.26%,P=0.014). CONCLUSION: Decitabine combined with arsenious acid has significant effect in the treatment of patients with higher-risk MDS and CMML and is well-tolerated. Gene mutation test results by next generation sequencing might be related to clinical response.
