Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

This article systematically analyzes the historical evolution of the name， origin， quality evaluation， harvesting， processing and other aspects of Picrorhizae Rhizoma by referring to the medical books， prescription books， and other documents of the past dynasties， combined with relevant modern research materials， in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history， Huhuanglian has been used as its official name， and there are also aliases such as Gehu Luze， Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times， Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions， and also produced in China， mainly in Xizang. In ancient times， it was harvested and dried in early August of the lunar calendar， while in modern times， it is mostly harvested from July to September， with the best quality being those with thick and crispy rhizomes without impurities， and bitter taste. Throughout history， Picrorhizae Rhizoma was collected， washed， sliced， and dried before being used as a raw material for medicine， it has a bitter and cold taste， mainly used to treat bone steaming， hot flashes， infantile chancre fever， and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results， it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia， or the rhizomes of P. kurrooa， can be used in famous classical formulas containing this medicinal herb， which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements， the dried raw products are used as medicine.

ObjectiveTo screen key genes associated with neuroblastoma （NB） diagnosis and prognosis using the Gene Expression Omnibus （GEO） database， and to investigate the expression and clinical significance of nucleoporin 93 （NUP93） in NB tissues. MethodsNB gene chip data （GSE73517， GSE49710， GSE19274） were retrieved from the GEO database. Differentially expressed genes （DEGs） commonly upregulated in high-risk groups were screened. The R2 database was then used to assess the prognostic value of DEGs that were commonly upregulated in the MYCN amplification group. Finally， NUP93 expression levels in the tissues from 60 NB， 25 ganglioneuroblastoma （GNB）， and 26 ganglioneuroma （GN） cases were measured by immunohistochemistry . ResultsTwenty-five DEGs were identified as commonly upregulated in high-risk groups. Among these， 10 genes （SIVA1， NUP93， STIP1， LSM4， RAI14， MYOZ3， KNTC1， TNFRSF10B， TACC3 and CEP152） showed significantly higher expression in MYCN-amplified subgroups （P＜0.05）. Survival analysis revealed that high NUP93 expression was associated with shorter overall survival （HR = 4.0， 95% CI： 3.0，5.3， P = 1.80 × 10⁻³⁴）. Immunohistochemistry results revealed that NUP93 expression in NB tissues was significantly higher than in GNB and GN tissues （P＜0.001）. NUP93 expression was positively correlated with high mitosis-karyorrhexis index （MKI； P=0.040）， poor differentiation （P＜0.001）， and MYCN expression （r_s = 0.793， P ＜0.001）. ConclusionsHigh expression of NUP93 is associated with high MKI and poor differentiation， and predicts unfavorable prognosis in patients with NB， suggesting it may promote tumor progression by regulating MYCN. NUP93 has the potential to be a novel diagnostic biomarker and therapeutic target for NB.

Houpo Sanwutang， included in the Catalogue of Ancient Classical Prescriptions （Second Batch）， was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining， statistical analysis， and data processing， combined with modern articles， this study employed bibliometrics to investigate the historical origin， composition， decoction methods， clinical application， and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty， it is recommended that 110.4 g Magnolia Officinalis Cortex， 55.2 g Rhei Radix et Rhizoma， and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first， and 1 000 mL should be taken from the decocted liquid. Following this， Rhei Radix et Rhizoma should be added for further decoction， and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL， and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi， relieving stuffiness and fullness， removing food stagnation， and regulating bowels. It can be used in treating abdominal distending pain， guarding， constipation， and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

Objective: To examine the association between incidence of hand-foot-mouth disease (HFMD) and meteorological factors, so as to provide the basis for the prevention and control of HFMD. Methods: The number of HFMD cases in Jiading District, Shanghai Municipality from 2016 to 2023 were collected through the Chinese Disease Prevention and Control Information System, and meteorological data were obtained from the Shanghai Meteorological Bureau. The associations of daily average temperature, daily average relative humidity, and daily average atmospheric pressure with the daily number of HFMD cases were analyzed using a distributed lag non-linear model (DLNM). Results: A total of 21 555 HFMD cases were reported in Jiading District from 2016 to 2023, with an average annual incidence of 132.57/100 000. There were 12 762 male cases (59.21%) and 8 793 female cases (40.79%). The main peak of incidence occurred from June to August, and the secondary peak was from October to December. DLNM analysis showed that the incidence risk of HFMD first increased and then decreased with the increase of daily average temperature, and first decreased and then increased with the prolongation of the lag time. The cumulative lag risk was higher when the daily average temperature ranged from 18.4 to 35.1 ℃, and the maximum cumulative lag effect was observed at 27.8 ℃ (RR=5.522, 95%CI: 4.751-6.370). The incidence risk of HFMD first increased and then decreased with the increase of daily average relative humidity, and first decreased, then increased and then decreased again with the prolongation of the lag time. The cumulative lag risk was higher when the daily average relative humidity ranged from 71.7% and 90.8%, and the maximum cumulative lag effect was observed at 81.8% (RR=1.603, 95%CI: 1.321-1.995). The incidence risk of HFMD decreased with the increase of daily average atmospheric pressure, and decreased with the prolongation of the lag time when the daily average atmospheric pressure was greater than 1 015.80 hPa. When the daily average atmospheric pressure was less than 1 015.80 hPa, the incidence risk of HFMD increased with the prolongation of the lag time. The maximum cumulative lag effect was observed at 986.80 hPa (RR=8.513, 95%CI: 1.401-36.625). Conclusion The incidence risk of HFMD in Jiading District initially increases and then decreases with increasing temperature and relative humidity, while it decreases with increasing atmospheric pressure, and these effects exhibit a lagged response.

AIM: To investigate the correlation of serum C-reactive protein(CRP)-to-albumin(ALB)ratio(CAR)and neutrophil-to-lymphocyte count ratio(NLR)with pathological staging and prognosis of retinopathy of prematurity(ROP), and the predictive value of its combined testing for the prognosis of infants.METHODS:Prospective study. A total of 147 children with ROP who were born in our hospital from March 2022 to September 2024 were served as the ROP group, and 100 premature infants without ROP were served as the control group in the same period. Fully automatic biochemical analyzer was used to detect serum CRP and ALB; the flow cytometry nucleic acid fluorescence staining was used to count neutrophils and lymphocytes, and the CAR and NLR were calculated. Spearman correlation was used to analyze the relationship of serum CAR and NLR with ROP staging. Logistic regression was used to analyze the factors affecting the prognosis of children with ROP. ROC curve was drew to analyze the predictive value of serum CAR and NLR for the prognosis of ROP.RESULTS: There was comparability between the ROP group and the control group. The ROP group had significantly higher serum CRP, CAR, neutrophil count, and NLR than the control group, and clearly lower ALB and lymphocyte count than the control group(all P<0.05). Children with stage IV ROP had clearly higher serum CAR and NLR than stages I, II, and III, and the differences among stages I, II, and III were significant(all P<0.05). Serum CAR and NLR were positively correlated with ROP staging(r=0.529, 0.587, all P<0.05), and there was a positive correlation between serum CAR and NLR(r=0.546, P<0.05). The poor prognosis group had clearly higher serum CAR and NLR than good prognosis group(all P<0.001). Elevated serum CAR and NLR were risk factors affecting the prognosis of children with ROP(all P<0.05). The AUC of serum CAR, NLR, and joint detection in predicting the prognosis of ROP children was 0.803, 0.825, and 0.938, respectively. The joint detection showed better predictive performance(Zcombinatoion-CAR=2.637, Zcombinatoion-NLR=2.528, all P<0.05).CONCLUSION:Serum CAR and NLR are elevated in children with ROP, and they are closely related to pathological staging and prognosis. The joint detection has a higher predictive value in evaluating the prognosis of ROP.

OBJECTIVES: To examine the changes in serum levels of endoplasmic reticulum stress (ERS) proteins GRP78/CHOP in patients with lupus nephritis (LN) and analyze their diagnostic value and association with renal pathological features. METHODS: From a sample bank established based on a multicenter cohort study of systemic lupus erythematosus (SLE), 60 LN patients and 35 SLE patients without renal involvement were randomly selected. ELISA was used to detect serum levels of GRP78 and CHOP in the patients to analyze their correlation with clinical features and their diagnostic ability for LN and active LN. MRL/lpr mice were used as an animal model of LN to examine their serum levels of GRP78 and CHOP expression and renal expressions of endoplasmic reticulum apoptosis-related proteins. RESULTS: Serum GRP78 and CHOP levels were significantly higher in LN patients than in SLE patients without renal involvement (P<0.05), and were also higher in active LN patients than in patients in the stable phase (P<0.05). Correlation analysis indicated that serum GRP78 and CHOP levels were positively correlated with SLEDAI scores and 24-h urinary protein. ROC analysis showed that CHOP had a high diagnostic ability for LN (AUC=0.762) and active LN (AUC=0.933). Consistent with the clinical findings, serum GRP78 and CHOP levels were elevated in LN mice, and the expressions of PERK and IRE1α pathway proteins were also increased in the kidneys of the mice. TUNEL staining showed increased renal cell apoptosis and elevated renal expressions of apoptosis-related proteins in LN mice. CONCLUSIONS Serum levels of GRP78/CHOP are increased in LN patients possibly in association with ERS-induced apoptosis mediated by the PERK/IRE1α dual pathway.

ObjectiveBased on the quality evaluation experience of "it is better to have a fragrant and strong aroma" summarized by materia medica of past dynasties， the chemical components of Sojae Semen Nigrum（SSN） and Sojae Semen Praeparatum（SSP） were systematically compared and analyzed， and the main fermentation products in different fermentation time were quantitatively analyzed， so as to clarify the transformation law of internal components in the processing process and provide scientific basis for the modern quality control of SSP. MethodUltra performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry（UPLC-Q-TOF-MS） was used for the structural identification of the chemical constituents of SSN and SSP， and with the aid of Progenesis QI v2.3 software， the negative ion mode was employed for principal component analysis（PCA） pattern recognition， and the data were analyzed with the aid of orthogonal partial least squares-discriminant analysis（OPLS-DA） for two-dimensional data to obtain S-plot， and components with |P|>0.1 were selected as the differential constituents. The contents of isoflavonoids in SSP during fermentation was determined by UPLC， and the samples were taken every 8 h in the pre-fermentation period and every 2 d in the post-fermentation period， and the dynamic changes of isoflavonoid contents in different fermentation stages were analyzed. The contents of amino acids and nucleosides in SSP and SSN from different fermentation stages were quantitatively analyzed by phenyl isothiocyanate（PITC） pre-column derivatization and high performance liquid chromatography（HPLC） gradient elution， and the contribution of flavor substances to the "delicious" taste of SSP was discussed by taste intensity value（TAV）. ResultA total of 19 kinds of differential components were screened out， mainly soybean saponins and isoflavones， and their contents decreased significantly or even disappeared after fermentation. In the pre-fermentation process of SSP， glycoside bond hydrolysis mainly occurred， and isoflavone glycosides in SSN were degraded and converted into the corresponding aglycones， the content of flavor substances such as amino acids increased gradually. In the post-fermentation process， protein degradation mainly occurred， after 8 d of post-fermentation， the content of isoflavones was basically stable， while the total content of amino acids increased by 8-40 times on average. Different amino acids form the special flavor of SSP， such as the TAV of glutamate is always ahead of other flavor substances， and sweet substances such as alanine and valine have made relatively great contributions to SSP. ConclusionBased on the law of constituent transformation， combined with the traditional evaluation index of "fragrant and strong"， it is difficult to control the fermentation degree of SSP by the existing standards in the 2020 edition of Chinese Pharmacopoeia. It is suggested that description of the characteristics of SSP be refined and changed to "fragrant， delicious and slightly sweet"， and at the same time， the post-fermentation index compounds such as glutamic acid， alanine and valine should be added as the quality control indicators of SSP， so as to standardize the production process and improve the quality of SSP.

Objective To study the expression levels of serum complement C1q/tumor necrosis factor-related protein 6(CTRP6)in women in early pregnancy and to explore its relationship with gestational diabetes mellitus(GDM).Methods Women at the Second Affiliated Hospital of Zhengzhou University from March 2021 to March 2022 were prospectively and consecutively selected from 10 to 13 weeks gestation for outpatient obstetric check-ups.The age,height,weight,and time of last menstruation of pregnant women were collected,and the levels of total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL),low density lipoprotein(LDL),fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),fasting insulin(FINS)and CTRP6 were measured in early pregnancy,and the pre-pregnancy body mass index(BMI),baseline BMI,prenatal BMI,and homeostatic model assessment of insulin resistance(HOMA-IR)were calculated.All pregnant women underwent a 75g oral glucose tolerance test at 24-28 weeks of gestation and were divided into GDM group and normal glucose tolerance(NGT)group according to the test results.The clinical data and laboratory indexes of the two groups in early pregnancy were compared,and the correlation between serum CTRP6 and various indexes in early pregnancy and its relationship with GDM were analyzed.Results A total of 213 maternal cases were enrolled,and 203 cases were completed for follow-up.Among them,52 mothers were diagnosed with GDM,with a GDM prevalence rate of 25.62%.Serum CTRP6,age,pre-pregnancy BMI,baseline BMI,antenatal BMI,TC,LDL,FPG,HbA1c,FINS,and HOMA-IR were higher in GDM group compared to NGT group,with a statistically significant difference(P<0.05).CTRP6 in early pregnancy was positively correlated with age,pre-pregnancy BMI,baseline BMI,prenatal BMI,TG,LDL,FPG,HbA1c,FINS,HOMA-IR,and negatively correlated with HDL(P<0.05).After correcting for age,BMI,glycolipid metabolism index and HOMA-IR,CTRP6 in early pregnancy remained an independent factor in the development of GDM.Conclusion Elevated serum CTRP6 in early pregnancy is associated with GDM and is an independent risk factor for GDM.

This article explored the treatment of laryngopharyngeal reflux disease （LPRD） from the perspective of ascending and descending of qi. It is believed that the disorder of qi movement of the middle jiao （焦） is the key to the pathogenesis of LPRD. The ascending and descending disorder of liver and lung is an important factor in its prolongation and progression. The treatment of LPRD should follow the nature of the spleen and stomach， with the focus on fortifying and transporting the spleen and the stomach， supplemented by soothing the liver and diffusing the lung. The herbs such as Cangzhu （Rhizoma Atractylodis）， Fuling （Poria）， Yiyiren （Semen Coicis）， Gegen （Radix Puerariae Lobatae） and Shanyao （Rhizoma Dioscoreae） could be used for fortifying and circuiting the center earth， and Chaihu （Radix Bupleuri）， Muxiang （Radix Aucklandiae）， Zhiqiao （Fructus Aurantii） and Baishao （Radix Paeoniae Alba） for soothing the liver and nourishing the blood to harmonize the ascending and descending. Jiegeng （Radix Platycodonis） and Xuanfuhua （Japanese Inula Flower） are supplemented to diffuse and direct lung qi downward thereby mediating the center jiao. In this way， the qi movement of the spleen and stomach is restored， and the ascending and descending between the liver and lung are harmonized， and therefore the disease is cureda.
