Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Autism Spectrum Disorder （ASD） is a neurodevelopmental disorder with rapidly increasing global prevalence， characterized by core symptoms of social communication deficits and stereotyped repetitive behaviors. Although genetic predisposition， abnormal epigenetic regulation， perinatal environmental exposure， and nutritional-metabolic imbalances are recognized as major risk factors， the precise etiological mechanisms remain incompletely understood. Current clinical management primarily relies on behavioral interventions， with limited pharmacological options accompanied by adverse effects. Recent studies have demonstrated the unique therapeutic value of active components from Chinese herbal medicine in ASD intervention. This article reviews the mechanisms underlying various Chinese herbal active components in ASD treatment， including improvements in synaptic dysfunction， blood-brain barrier impairment， neurotransmitter regulation， cerebellar dysfunction， immune dysregulation and neuroinflammation， oxidative stress， programmed neuronal cell death， and lipid metabolism. These bioactive components exhibit multi-target and multi-pathway regulatory effects， providing novel therapeutic strategies and directions for ASD.

Shengjiangsan is a classic formula for treating warm diseases with wide clinical application and accurate efficacy. There are different opinions on the origin of this formula and lacks key information research on this formula. Therefore， in this study， we conducted systematic research into the historic origin， composition， and other key information of this Shengjiangsan. Results showed that Shengjiangsan has different versions， with "Neixian Fufang"， "Jiawei Jianghuangwan"， "Peizhensan"， and "Taijiwan" being the same formula with different names. Shengjiangsan was first recorded as "Neixian Fufang" in Wanbing Huichun written by GONG Tingxian from the Ming dynasty， inherited and developed by YANG Lishan from Qing dynasty， and has been passed down to modern times. Pills and powder are two main forms of Shengjiangsan， and powder has become more popular nowadays. According to the measurement system of Ming and Qing dynasties， the recommended dosage and usage of Shengjiangsan are as follows. For the pill version of Shengjiangsan， Bombyx Batryticatus of 74.6 g， Curcumae Longae Rhizoma of 9.325 g， Cicadae Periostracum of 9.325 g， and Rhei Radix et Rhizoma of 149.2 g were processed into pills for preparation. Single dosage is Bombyx Batryticatus of 1.15 g， Curcumae Longae Rhizoma of 0.14 g， Cicadae Periostracum of 0.14 g， and Rhei Radix et Rhizoma of 2.3 g， with halved dosage applied for children. For the powder version of Shengjiangsan， the dosage varied in accordance with the severity of the disease. Bombyx Batryticatus of 1.84 g， Curcumae Longae Rhizoma of 0.28 g， Cicadae Periostracum of 0.92 g， and Rhei Radix et Rhizoma of 3.68 g were processed into powder for patients with mild symptoms. Bombyx Batryticatus of 2.48 g， Curcumae Longae Rhizoma of 0.37 g， Cicadae Periostracum of 1.23 g， and Rhei Radix et Rhizoma of 4.91 g were processed into powder for patients with severe symptoms. Bombyx Batryticatus of 3.68 g， Curcumae Longae Rhizoma of 1.84 g， Cicadae Periostracum of 0.55 g， and Rhei Radix et Rhizoma of 7.36 g were processed into powder for patients with critical conditions. In this formula， four herbs were ground to fine powder. For patients with mild symptoms， the whole formula was divided into four dosages， and each dosage weighed 6.71 g. The 200 mL yellow rice wine and 18.65 g honey were added， and the solution was stirred and taken cold till full recovery. For patients with severe symptoms， the whole formula was divided into three dosages， and each weighed 8.95 g. 300 mL yellow rice wine and 27.98 g honey were added， and the solution was stirred and taken cold. For patients with critical conditions， the whole formula was divided into two dosages， and each weighed 13.43 g. 400 mL yellow rice wine and 37.3 g honey were added， and the solution was stirred and taken cold. Shengjiangsan has the effect of ascending lucidity and descending turbidity， dissipating wind， and clearing heat. It is specialized in treating severe heat in exterior， interior， and triple energizers in warm diseases and has a wide modern clinical application. In this study， the historic evolution and key information of Shengjiangsan were reviewed and analyzed， and the key information table of Shengjiangsan was attached， serving as a reference for scholars' research and a theoretical basis for its market transformation.

Objective To compare the clinical outcomes of the clomiphene citrate(CC)dual stimulation protocol and the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved in POSEIDON patients with low expected prognosis.Methods The clinical data from patients who underwent in vitro fertilization(IVF)or intracytoplasmic sperm injection(ICSI)at the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from May 2016 to December 2023 were analyzed retrospectively.According to the POSEI-DON criteria,including POSEIDON group 3 and group 4,which were treated with the CC dual stimulation protocol(the CC group)and the luteal-phase ovarian stimulation protocol after the natural cycle oocytes retrieval(the natural cycle group).The basic data and clinical outcomes of the two ovulation protocols were analyzed,and the main observations included the number of oocytes retrieved,the cumulative clinical pregnancy rate and the cumulative live birth rate,and explored the impact of ovulation promotion regimens on clinical outcomes through binary logis-tic regression.Results On the whole,there was no significant difference in the total number of oocytes retrieved,cumulative clinical pregnancy rate and live birth rate between the CC group and the natural cycle group(all P>0.05),And in POSEIDON group 4,the numbers of oocytes retrieved in the follicular phase of the CC group were higher than those in the natural cycle group,whereas the number of oocytes retrieved in the luteal phase of natural cycle group were higher,and the difference was statistically significant(P<0.05).After logistic regression analysis,the ovulation stimulation protocols did not affect the cumulative clinical pregnancy rate and live birth rate of POSEI-DON 3 and 4 group(P>0.05).Conclusions For the POSEIDON patients with a low expected prognosis,the clinical effectiveness of the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved is not inferior to that of the CC dual stimulation protocol.In POSEIDON group 4,on the premise that the AMH levels of patients in the natural cycle group were lower than those in the CC group,who underwent natural cycle ovulation followed by luteal phase induction achieved similar clinical outcomes to those of the CC dual stimulation protocol group.Therefore,the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved should be more clinically recommended for POSEIDON group 4 patients.

Objective To study the effects of different clearance conditions(equal upper and lower axial clearance,change of upper/lower axial clearance,axial displacement of blades)on efficiency and hemolysis performance of blood pump.Methods The blood pumps under three kinds of clearance conditions were numerically simulated by computational fluid dynamics.Results For efficiency,when the upper and lower axial clearance was equal,the lower axial clearance was unchanged and the upper axial clearance was reduced,the efficiency of blood pump could be improved by 0.85%,1.71%and 2.90%,respectively.While the upper shaft clearance remained unchanged,the lower shaft clearance was decreased by 1.18%.For hemolysis,the increase of the clearance could reduce the hemolysis index(HI)under the first two clearance conditions,while the axial migration of the blade wheel would increase the HI.When the upper axial clearance was unchanged and the lower axial clearance was 0.3 mm,the HI was the largest,which was 8.65×10-4.When the upper and lower axial clearance was 0.7 mm,the HI was the smallest,which was 4.51×10-4.Conclusions Improving blood pump clearance is helpful to optimize the performance of blood pump.This study can provide some references for the design and optimization of interstitial structure of blood pump.

Objective:To investigate the influencing factors and perinatal outcomes associated with monozygotic twins (MZT) following elective single embryo transfer (eSET) via in vitro fertilization or intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). Methods:A retrospective cohort study was conducted on 12 079 patients who achieved pregnancy after undergoing IVF/ICSI-eSET at Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University between January 2015 and September 2023. Patients were stratified into two groups based on ultrasound findings 30 d post-transfer: singleton pregnancy group and MZT pregnancy group. Finally, 300 MZT and 1 500 single pregnancies, which were randomly matched according to 1∶5 were included by study period. General patients' characteristics, embryo-related factors, and perinatal outcomes were compared between the two groups. A multivariate logistic regression model was employed to identify risk factors for MZT after single embryo transfer, adjusting for potential confounding variables.Results:The incidence of twin pregnancy following single embryo transfer was 2.48% (300/12 079), which was higher than that of naturally conceived monozygotic twin pregnancy. No significant difference was found in baseline characteristics between the two groups (all P>0.05). The blastocyst transfer rate was higher in the MZT pregnancy group [93.3% (280/300)] than in the singleton pregnancy group [88.8% (1 332/1 500), P=0.022]. Multivariate logistic regression analysis also showed that blastocyst transfer was associated with an increased risk of MZT ( OR=0.552, P=0.016, 95% CI: 0.341-0.894). Analysis of blastocyst cycles showed that the risk of MZT was higher when transferring high-quality blastocysts [79.6% (223/280) vs. 67.8% (903/1 332), P<0.001], where as a trophectoderm (TE) grading of C [20.4% (57/280) vs. 32.2% (429/1 332), P<0.001] had a lower risk of MZT. After adjusting for confounding factors, the risk of MZT was found to increase with the transfer of blastocysts with a B-grade inner cell mass (ICM) ( OR=0.601, P=0.001, 95% CI: 0.442-0.819) and A/B grade TE (grade A: OR=2.951, P<0.001, 95% CI: 1.980-4.399; grade B: OR=1.840, P<0.001, 95% CI: 1.315-2.576). The risk of complications during pregnancy [47.7% (143/300) vs. 19.3% (289/1 500), P<0.001], preterm labor [55.1% (140/254) vs. 7.4% (101/1 368), P<0.001], and the risk of stillbirth [3.7% (11/300) vs. 1.5% (22/1 500), P=0.016] were significantly higher in the MZT pregnancy group than in the singleton pregnancy group. Conclusion:Assisted reproductive technology may contribute to the risk of MZT. Transfer of blastocysts, particularly those with loose ICM arrangement and dense TE arrangement, appears to increase the risk of MZT in patients undergoing eSET.

Objective:To analyze the clinical characteristics of familial hypercholesterolemia (FH) in children and provide a basis for clinical diagnosis and individualized treatment.Methods:Case series study. Clinical data of 24 children with FH, who were admitted to the Department of Endocrinology in Capital Center for Children′s Health, Capital Medical University, from January 2018 to January 2025, were analyzed. Follow-ups were performed every 3-6 months and ended in January 2025. According to the results of genetic testing, the children were divided into homozygous familial hypercholesterolemia (HoFH) group and heterozygous familial hypercholesterolemia (HeFH) group. The blood lipid levels of different subtypes, the efficacy of different treatments, and clinical outcomes were compared by Mann-Whitney U test. Results:The 24 children were from 17 families, including 14 males and 10 females, with a diagnostic age of 5.0 (3.0, 9.5) years. Genetic testing results showed that 22 cases (92%) had LDLR gene variants and 2 cases (8%) had APOB gene variants, all of which were inherited from parents. There were 5 cases (21%) of HoFH and 19 cases (79%) of HeFH, and 4 previously unreported new loci were identified. There were 6 children (25%) presented with xanthomas, including 5 cases of HoFH and 1 case of HeFH. The level of low-density lipoprotein cholesterol (LDL-C) in the HoFH group was significantly higher than that in the HeFH group ( P<0.05). Regarding treatment, 11 children received dietary control without taking medicine, 6 were treated with statins, 3 with ezetimibe, and 3 with statins combined with ezetimibe, and 1 underwent liver transplantation. None of the children receiving only dietary control achieved the target LDL-C level (<3.49 mmol/L or a reduction of >50%), and there was no statistically significant difference in LDL-C before and after dietary control ( P=0.158). After treatment with statins and (or) ezetimibe, LDL-C decreased in 12 children ( P<0.05); among them, 6 cases (all HeFH) reached the target LDL-C level. There was no statistically difference in LDL-C levels before and after treatment with atorvastatin and ezetimibe in 5 HoFH children( P>0.05). One HoFH child had LDL-C reduced to the normal range after liver transplantation. No serious adverse reactions were observed in all children during drug treatment. In the detection of vascular-related complications among 12 HeFH children, only 1 child had a slight thickening of the bilateral carotid intima-media, while no abnormalities were found in the others. Conclusions:Xanthoma is a characteristic manifestation of FH, but its incidence is relatively low in HeFH children. Family history and genetic testing are key evidences for the diagnosis of FH. Dietary control has limited efficacy in children with FH, and drug treatment should be initiated as early as possible. LDL-C levels in HoFH children are more difficult to control, if drug treatment shows poor efficacy, liver transplantation may be a better option.

Objective To investigate the impact of variations in volute cross-sectional area on the flow characteristics and hemolytic performance of centrifugal blood pumps by designing six volute structures.Methods Computational fluid dynamics and the Lagrangian method were used to analyze flow characteristics and predict hemolysis in blood pumps with different volute designs.Results The annular volute pump showed the poorest hydraulic performance,while the hydraulic performance of the S-shaped volute was the best,which was improved by 35.29％compared to that of the annular volute.Some volutes experienced stagnation zones at the helical inlet(0°-90°)and significant backflow at the outlet(270°-360°).The downward concave-shaped volute had the highest hemolysis index(HI),i.e.,9.59×10-4.Meanwhile,the HI of the annular volute was the lowest,which was 71.85％less than the concave-shaped volute.Conclusions Reducing the gradient of the area variation at the helical inlet and outlet can prevent flow stagnation and backflow.A higher HI arises due to the prolonged exposure of red blood cells to high shear stress.This study provides a theoretical basis for designing and optimizing volute structures of centrifugal blood pumps.

The risk of complications during pregnancy [47.7% (143/300) vs. 19.3% (289/1 500), P<0.001], preterm labor [55.1% (140/254) vs. 7.4% (101/1 368), P<0.001], and the risk of stillbirth [3.7% (11/300) vs. 1.5% (22/1 500), P=0.016] were significantly higher in the MZT pregnancy group than in the singleton pregnancy group. Conclusion:Assisted reproductive technology may contribute to the risk of MZT. Transfer of blastocysts, particularly those with loose ICM arrangement and dense TE arrangement, appears to increase the risk of MZT in patients undergoing eSET.

Objective The aim of this study is to examine the Chinese version of Visual Prostate Symptom Score(CVPSS)and the International Prostate Symptom Score(IPSS)in the assessment of lower urinary tract symptoms in BPH pa-tients.Methods By using convenient sampling,inpatients in the urology department of a tertiary grade A hospital in Shanghai were selected as the survey subjects from March 2023 to March 2024.The lower urinary tract symptoms of the patients were eval-uated using the self-designed general information questionnaire.And the CVPSS and IPSS with their urine flow rate were meas-ured.A comparative analysis was conducted from aspects such as internal consistency,correlation of item scores,completion time of the scale,and assistance rate.Results A total of 246 patients with BPH were recruited.The total score and life quality score were 13.93±3.55 and 4.23±1.02 by CVPSS.And the total score and life quality by IPSS was 18.33±7.55 and 4.36±1.02,respectively.The Cronbach's α coefficient were 0.761 and 0.787,respectively.The time taken on CVPSS was less than that on IPSS(P＜0.01).And the rate of needing assistance was 23.58％for CVPSS,which was significantly lower than that(65.24％)for IPSS.Conclusion CVPSS is significantly correlated with the corresponding items and total scores of IPSS,as well as the quality of life.Moreover,it takes less time and can be used as a simple and effective self-assessment tool for lower urinary tract symptoms in elderly BPH patients with lower education levels.It reduces the burden of medical staffs as well.
