In the special periods of puberty,menstruation,pregnancy,postpartum,and perimenopause of the female life,the drastic changes in qi and blood of the women cause the redistribution of qi,blood,yin and yang in those periods,which easily leads to various disordered states of disharmony between nutrient qi and defensive qi,disharmony between qi and blood,and imbalance of yin and yang.By analyzing the mechanism of the disharmony between nutrient qi and defensive qi in the special periods of puberty,menstruation,pregnancy,postpartum,and perimenopause of the female life,this paper proposes the approach of harmonizing nutrient qi and defensive qi to treat menstrual disorders,leukorrheal disease,gravid trouble,and parturition problems.Moreover,It is recommended that Guizhi Tang(Cinnamomi Ramulus Decoction),the chief of ZHANG Zhong-Jing's prescriptions and having the actions of releasing muscles and harmonizing nutrient qi and defensive qi,and activiting qi and harmonizing yin and yang,can be used to treat gynecological diseases through the modification.The utilization of Guizhi Tang for the treatment of gynecological diseases at various periods of women's lives will expand the application of classical prescriptions in treating gynecological diseases.

Objective To investigate the expression of serum microRNA-29b(miR-29b),microRNA-199a(miR-199a),and microRNA-19a-3p(miR-19a-3p)in patients with acute cerebral infarction(ACI)and their relationship with disease severity and prognosis.Methods(1)Rats were randomly divided into a control group(Control group)and a model group(Model group),with 6 rats in each group.ACI was induced in the model group using the modified Longa suture method;the expression levels of miR-29b,miR-199a,miR-19a-3p in rat serum and brain tissue were detected and analyzed.(2)A total of 106 ACI patients diagnosed at Tangshan People's Hospital from June 2023 to June 2024 were enrolled as the study group,and 108 healthy individuals who underwent physical check-ups at the same hospital during the same period were chosen as the control group.According to the NIHSS evaluation results,the study group patients were assigned into mild(42 cases),moderate(34 cases),and severe(30 cases)groups.Based on the mRS evaluation results,the patients were assigned into good prognosis(68 cases)and poor prognosis(38 cases)groups.Real-time fluorescence quantitative PCR was applied to measure the expression levels of serum miR-29b,miR-199a,and miR-19a-3p.Pearson correlation analyzed the correlation between serum miR-29b,miR-199a,miR-19a-3p levels and NIHSS score and mRS score in ACI patients.The risk factors for poor prognosis in ACI patients were analyzed using multivariate logistic regression.ROC curves were used to analyze the predictive value of serum miR-29b,miR-199a,miR-19a-3p levels and NHISS scores in poor prognosis of ACI patients.Results(1)Compared with the Control group,the levels of miR-199a and miR-19a-3p in the serum and brain tissue of the Model group rats were significantly increased,while the level of miR-29b was significantly decreased(P<0.05);(2)Compared with the control group,as the severity of ACI patients gradually increased,the levels of serum miR-199a and miR-19a-3p unusually increased in the mild,moderate,and severe groups,while the level of miR-29b was significantly decreased(P<0.05).The NHISS score,miR-199a and miR-19a-3p levels in the poor prognosis group were significantly higher than those in the good prognosis group,while miR-29b was significantly lower than that in the good prognosis group(P<0.05).The levels of serum miR-199a and miR-19a-3p were positively correlated with NIHSS score;the level of miR-29b was negatively correlated with NIHSS score(P<0.05).Elevated serum miR-199a and miR-19a-3p levels and increased NHISS score were independent risk factors for poor prognosis in ACI patients,and elevated serum miR-29b levels were protective factors for poor prognosis in ACI patients(P<0.05).The combined prediction of poor prognosis in ACI patients using serum miR-29b,miR-199a,miR-19a-3p levels and NHISS scores yielded an ACI of 0.988,which was superior to individual predictions(Z=2.878,3.551,3.300,3.452,P<0.05).Conclusion The serum expression levels of miR-199a and miR-19a-3p were significantly up-regulated,while miR-29b levels significantly down-regulated,which were related to the disease severity and prognosis.The the combination of the three miRNAs had certain value in predicting the poor prognosis of patients.MiR-29b,miR-199a,and miR-19a-3p can be used as important predictors to evaluate the progression and prognosis of ACI patients.

Danggui Sinitang is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Han dynasty. It is composed of Angelicae Sinensis Radix， Cinnamomi Ramulus， Paeoniae Radix Alba， Asari Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma， Tetrapanacis Medulla， and Jujubae Fructus and serves as a classic formula for treating the syndrome of blood deficiency and cold reversal. This study systematically reviews the records of Danggui Sinitang in ancient Chinese medicine books of various dynasties and the modern clinical applications to probe into the composition， plant species， processing， dosage， decocting method， and indications of Danggui Sinitang， aiming to provide a reference for the development and clinical application of this classic formula. The review of the records showed that there were a variety of records of Danggui Sinitang with different composition， and the composition of this formula listed in the Treatise on Cold Damage has a significant impact on later generations and has been used by medical practitioners throughout history. Although the dosage of some drugs decreased during the Ming and Qing dynasties， the medical practitioners continued to use the original formula. In terms of processing， although there were slight changes in the processing of Angelicae Sinensis Radix， Paeoniae Radix Alba， Glycyrrhizae Radix et Rhizoma， and Tetrapanacis Medulla， the original processing method was inherited. In terms of indications， Danggui Sinitang was designed to treat cold reversal due to blood deficiency and dysentery. Furthermore， it was used to treat headache， convulsive disease， infantile convulsion， and private part adduction in the Ming and Qing dynasties. Nowadays， this formula is mostly used to treat diabetes peripheral neuropathy， rheumatoid arthritis， dysmenorrhea， Raynaud's disease and other diseases. In terms of precautions， ancient physicians believed that Danggui Sinitang should not be taken by pregnant women and should only be used for limb chills caused by blood deficiency and cold coagulation. For limb chills caused by other reasons， this formula should not be used indiscriminately. Modern research has not reported any serious adverse reactions related to this formula. Danggui Sinitang has a definite therapeutic effect. In subsequent research and development， quality control standards of Danggui Sinitang should be established while its safety is ensured， and the related preparations should be developed and applied.

Objective:To investigate the changes of artemin protein expression in diabetic peripheral neuropathy (DPN) and to explore the regulatory effect of human adipose-derived stem cell (ADSC) exosomes on the change of artemin protein expression.Methods:This research was a prospective observational clinical research combined with experimental research. Thirteen DPN patients (9 males and 4 females, aged 32 to 68 years) who were admitted to the First Affiliated Hospital of Air Force Medical University (hereinafter referred to as our hospital) from May 2022 to October 2023 and met the inclusion criteria were selected as DPN group, and 5 non-diabetes patients (4 males and 1 female, aged 29 to 61 years) who were admitted to our hospital in the same period of time and met the inclusion criteria were selected as control group. The toe nerve or sural nerve tissue in the abandoned tissue after debridement or amputation of patients in the two groups was collected. The pathological changes of nerve tissue were observed after hematoxylin-eosin staining; the protein expressions of S100β and artemin in nerve tissue were observed after immunofluorescence staining, and the artemin protein expression was quantified; the protein and mRNA expressions of artemin were detected by Western blotting and real-time fluorescent quantitative reverse transcription polymerase chain reaction, respectively (the sample number in DPN group and control group was 13 and 5, respectively). Twelve male C57BL/6 mice aged 3 to 5 days were collected to isolate Schwann cells, and the cells were divided into conventional culture group cultured routinely, high glucose alone group (cultured with high concentration of glucose solution only), and high glucose+exosome group (cultured with high concentration of glucose solution and extracted human ADSC exosomes). After 24 hours of culture, the cell proliferation activity was detected by cell counting kit 8 ( n=6). After 48 hours of culture, the protein expression of artemin was detected by Western blotting ( n=3). Results:Compared with those in control group, the neural supporting cells decreased and the inflammatory cells increased in the nerve tissue of patients in DPN group, showing typical manifestations of nerve injury. Immunofluorescence staining showed that compared with those in control group, the nuclei was more, and the protein expression of S100β was lower in nerve tissue of patients in DPN group. The protein expression of artemin in nerve tissue of patients in DPN group was 71±31, which was significantly lower than 1 729±62 in control group ( t=76.92, P<0.05). Western blotting detection showed that the protein expression of artemin in nerve tissue of patients in DPN group was 0.74±0.08, which was significantly lower than 0.97±0.06 in control group ( t=5.49, P<0.05). The artemin mRNA expression in nerve tissue of patients in DPN group was significantly lower than that in control group ( t=7.65, P<0.05). After 24 hours of culture, compared with that in conventional culture group, the proliferation activities of Schwann cells in high glucose alone group and high glucose+exosome group were significantly decreased ( P<0.05); compared with that in high glucose alone group, the proliferation activity of Schwann cells in high glucose+exosome group was significantly increased ( P<0.05). After 48 hours of culture, compared with those in conventional culture group, the protein expressions of artemin of Schwann cells in high glucose alone group and high glucose+exosome group were significantly decreased ( P<0.05); compared with that in high glucose alone group, the protein expression of artemin of Schwann cells in high glucose+exosome group was significantly increased ( P<0.05). Conclusions:The protein expression of artemin in nerve tissue of DPN patients is lower than that in normal nerve tissue, which may be related to the reduction of proliferation activity of Schwann cells by high glucose. Human ADSC exosomes may improve the proliferation activity of Schwann cells by increasing artemin protein expression, thereby delaying the progression of DPN.

Objective To assess the effects of low-dose esketamine on the median effective dose(ED50)of ciprofol for anesthesia induction in painless gastrointestinal endoscopy.Methods Fifty-nine pa-tients underwent elective painless gastrointestinal endoscopy,26 males and 33 females,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ,were divided into two groups by random number table method:esketamine combined with ciprofol group(group EC,n = 29)and ciprofol group(group C,n = 30).Group EC received intravenous injection of esketamine 0.3 mg/kg and group C received the same amount of normal saline 2 minutes before administration of ciprofol.The initial anesthesia induction dose of ciprofol was 0.4 mg/kg.If a positive reaction occurs during the examination,the next patient will receive an increase dose of propofol 0.04 mg/kg,otherwise will decrease by propofol 0.04 mg/kg.The positive reaction was defined that the patient's BIS can not be decreased to 60 2 minutes after anesthesia induction,or the cough or body movement reaction occur at level 2 or above when entering the mirror.The dosage of ciprofol,recovery time,discharge time,the occurrence of intraoperative and postoperative adverse reactions were recorded.The ED50,95%effective dose(ED95)and 95%confidence interval(CI)of the two groups were calculated by Probit probability regression analysis.Results Compared with group C,the dosage of ciprofol,the incidence of hypotension and frequency of administration of vasoactive drugs during the exami-nation process in group EC were significantly reduced(P＜0.05).The ED50 of ciprofol for anesthesia in-duction in painless gastrointestinal endoscopy in group EC was 0.21 mg/kg(95%CI 0.12-0.25 mg/kg)and the ED95 was 0.32 mg/kg(95%CI 0.26-0.39 mg/kg).The ED50 of ciprofol for anesthesia induction in painless gastrointestinal endoscopy in group C was 0.37 mg/kg(95%CI 0.32-0.40 mg/kg)and the ED95 was 0.48 mg/kg(95%CI 0.43-0.54 mg/kg).The ED50 and ED95 of ciprofol for anesthesia induction in painless gastrointestinal endoscopy in group EC was significantly lower than that in group C(P＜0.05).There was no significant difference in other frequency of adverse events between the two groups.Conclusion Esketamine 0.3 mg/kg can reduce the ED50 of ciprofol in painless gastrointestinal endoscopy and reduce the dosage of ciprofol during the examination process,which is safe for painless gastrointestinal endoscopy with stable intraoperative circulation.

Purpose To explore the application value of contrast enhancement boost(CE-Boost)technique in image quality of tumors and their feeding arteries in preoperative evaluation of renal cancer patients.Materials and Methods A total of 36 renal cancer patients in People's Hospital Affiliated to Shandong First Medical University from August 2022 to May 2023 with pathologically confirmed were retrospective collected.All patients underwent renal enhanced CT.The cortical phase images were post-processed using the CE-Boost technique to obtain CE-Boost images.The cortical phase images were set as group A and the CE-Boost images were set as group B.The CT value and image noise(SD)of abdominal aorta,renal artery,tumor and its adjacent renal cortex,and SD of the vertical spinal muscle on both sides of the spine of two groups were measured and recorded,and then the signal-to-noise ratio and contrast-to-noise ratio of tumor,abdominal aorta and renal artery were calculated.The image quality of the tumor,tumor feeding artery and renal artery was scored on 4 points by 2 doctors with double-blind method.Results The signal-to-noise ratio,contrast-to-noise ratio and CT value of group B were significantly higher than those of group A(t=-27.385--5.267,all P<0.05).The SD of tumor,abdominal aorta,right and left renal artery were not significantly different between group A and B(t=-1.849-0.993,all P>0.05).The subjective score of tumor in group A and B were no significant difference(Z=-1.490,P=0.136).However,the subjective score of tumor feeding arteries and renal arteries were significantly higher in group B than in group A(Z=-3.512,P=0.000;Z=-2.127,P=0.033).Conclusion The CT CE-Boost technique can improve the image quality of renal enhanced CT and provide visualization of tumor feeding arteries.

Objective:To analyze the clinical outcomes of initial radioactive iodine 131I therapy (RIT) for patients with familial differentiated thyroid cancer (FDTC) and sporadic differentiated thyroid cancer (SDTC), along with their influencing factors. Methods:The clinical data of 120 FDTC and 480 SDTC patients who received RIT at the Department of Nuclear Medicine, Tianjin Medical University General Hospital from January 2016 to January 2022 were retrospectively analyzed. These patients, categorized into the FDTC and SDTC groups, were further divided into three subgroups based on their response to initial RIT: no evidence of disease (NED), biochemical persistence of disease (BPD), or structural/functional persistence of disease (S/FPD). For the NED subgroup, the disease-free survival (DFS) was analyzed. For the BPD and S/FPD subgroups, the progression-free survival (PFS) was investigated. Furthermore, risk factors for failure to reach the NED status were identified.Results:After initial RIT, 56 (46.7%), 50 (41.7%), 14 (11.6%) patients in the FDTC group reached the NED, BPD, and S/FPD statuses, respectively, while 284 (59.1%), 160 (33.3%), 36 (7.5%) and SDTC patients in the SDTC group were in the NED, BPD, and S/FPD statuses, respectively ( χ2 = 10.10, P = 0.013). The last follow-up revealed that 71 (59.1%), 36 (30.1%), 13 (10.8%) patients in the FDTC group were in the NED, BPD and S/FPD statuses, respectively, while 337 (70.2%), 114 (23.7%), 29 (6.1%) patients in the SDTC group reached the NED, BPD and S/FPD statuses, respectively ( χ2 = 8.99, P = 0.026). The F-NED and S-NED subgroups exhibited 5-year DFS rates of 92.4% and 97.4%, respectively, the F-BPD and S-BPD subgroups displayed 5-year PFS rates of 88.3% and 90.8%, respectively, while the F-S/FPD and S-S/FPD subgroups yielded in 5-year PFS rates of 78.2% and 79.6%, respectively. Univariate binary logistic regression analysis indicated that the maximum diameter of tumors, T stage, M stage, recurrence risk stratification, and postoperative stimulated thyroglobulin (p-sTg) were correlated with the achievement of the NED status ( χ2=6.37-13.10, P < 0.05). Multivariable binary logistic regression analysis showed that T stage and p-sTg were independent risk factors in the achievement of the NED status ( χ2=0.11-11.33, P < 0.05). Conclusions:The response to initial RIT assists in guiding the development of subsequent treatment and follow-up strategies for DTC patients. Given that the SDTC patients exhibited better outcomes than the FDTC patients, more alertness should be paid to the RIT for FDTC patients. For patients with higher p-sTg and T stage, the initial RIT dose and follow-up interval should be increased and reduced respectively as appropriate.

OBJECTIVE To discuss the factors affecting the blood concentration of high-dose methotrexate （HD-MTX） and the occurrence of adverse drug reactions （ADR） when treating lymphoma with HD-MTX. METHODS From July 2020 to November 2021， the information of HD-MTX patients who had been monitored for HD-MTX blood drug concentration in the First Affiliated Hospital of Guangdong Pharmaceutical University was collected by retrospective analysis， such as medical record number， age， sex， height， body mass， chemotherapy plan， dosage； test indexes such as alanine transaminase， aspartate transaminase， total bilirubin， creatinine clearance （CrCl）， albumin （ALB） and other indexes were also collected before and after administration. The blood concentrations （c6 h， c24 h， c48 h） of HD-MTX were recorded， drug information of proton pump inhibitors （PPIs） was extracted and used， and ADR occurring within 48 h after administration were all evaluated. Single factor analysis， multiple linear regression and χ2 test were used to analyze the influential factors. RESULTS A total of 133 patients were included in this paper. The results of the single factor analysis of HD-MTX blood drug concentration showed that age， CrCl had an effect on c 6 h （P＜0.05）； age， CrCl and ALB had an effect on c24 h （P＜0.05）； age， body mass index （BMI）， CrCl， combined use of PPIs and ALB had an effect on c48 h （P＜0.05）. The results of multiple linear regression analysis showed that age and CrCl had no effect on c 6 h （P＞0.05）， age was the main influential factor of c 24 h （P＜0.05）， and CrCl and combined use of PPIs were the main influential factors of c48 h （P＜0.05）； the coefficient of variance expansion was between 1 and 3.5， indicating that the analysis results were acceptable. The overall incidence of adverse reactions was 51.13%， of which the blood and lymphatic system reactions were the most common. The results of the influential factors of ADR showed that age， BMI， liver function and CrCl had effect on the incidence of ADR （P＜0.05）. CONCLUSIONS During the process of HD-MTX in the treatment of lymphoma， the patient’s age， CrCl and combined use of PPIs should be considered， and the patient’s blood concentration should be monitored； at the same time， the age of patients， BMI， liver function and CrCl have an impact on the incidence of ADR.

OBJECTIVE: To retrospectively analyze the clinical phenotypes and genetic variants in two Chinese pedigrees affected with Hereditary hypofibrinemia (IFD) and explore their molecular pathogenesis. METHODS: Two probands and their pedigree members were admitted to the First Affiliated Hospital of Wenzhou Medical University on March 30, 2021 and May 27, 2021, respectively. Clinical phenotypes of the probands were collected, and blood clotting indexes of the probands and their pedigree members were determined. Variants of the FGA, FGB and FGG genes were analyzed by Sanger sequencing, and candidate variants were verified by sequence comparison. Bioinformatic software was used to analyze the conservation of the amino acids and pathogenicity of the proteins. Alteration in protein structure and intermolecular force before and after the variant was analyzed by simulating the protein model. RESULTS: Proband 1, a 18-year-old male, had significantly low plasma fibrinogen activity (Fg:C) and plasma fibrinogen antigen (Fg:Ag), respectively at 0.80 g/L and 1.00 g/L. Proband 2, a 43-year-old male, had slightly low Fg:C and Fg:Ag at 1.35 g/L and 1.30 g/L, respectively. The Fg:C and Fg:Ag of proband 1's father, proband 2's father and son were also below the normal level. Genetic testing showed that proband 1 had harbored a heterozygous missense variant of c.688T>G (p.Phe230Val) in exon 7 of the FGG gene, which was inherited from his father. Proband 2, his father and son all had harbored a heterozygous variant of c.2516A>C (p.Asn839Thr) in exon 6 of the FGA gene. Homology analysis showed that the Phe230 and Asn839 residues were highly conserved among homologous species. Bioinformatic analysis predicted that both p.Phe230Val and p.Asn839Thr were pathogenic variants. CONCLUSION Analysis of protein simulation model showed that the p.Asn839Thr variant has changed the hydrogen bo`nd between the amino acids, thus affecting the stability of the protein structure. The heterozygous missense variants of p.Phe230Val and p.Asn839Thr probably underlay the IFD in the two pedigrees.

Objective:To study whether male was the risk factor for prognosis of patients with differentiated thyroid cancer (DTC) after 131I treatment based on propensity score matching (PSM) method. Methods:From April 2016 to January 2021, 1 677 patients (age: 11-84 (43.9±12.5) years) with DTC who underwent total thyroidectomy and received 131I treatment in Tianjin Medical University General Hospital were retrospectively enrolled and patients were divided into male group ( n=546) and female group ( n=1 131). The evaluation results of patients were divided into excellent response (ER), indeterminate response (IDR), biochemical incomplete response (BIR) and structural incomplete response (SIR). Among them, ER and IDR were divided into good prognosis group, and BIR and SIR were divided into poor prognosis group. The PSM method was adopted to process all data to reduce the influence of data bias and confounding variables. χ2 test was used for data analysis. Multivariate logistic regression was used to analyze the risk factors affecting prognosis, and ROC curve was used to analyze the relationship between stimulated thyroglobulin (sTg) level and poor prognosis. Results:Before PSM, the proportion of male patients with poor prognosis was significantly higher than that of female patients (21.2%(116/546) vs 14.0%(158/1 131); χ2=17.53, P=0.001). After PSM, there was no difference in the proportion of poor prognosis between male and female groups (19.9%(107/537) vs 15.6%(84/537); χ2=5.43, P=0.143). Multivariate logistic regression analysis showed that male (odds radio ( OR)=1.439 (95% CI: 1.016-2.038), P=0.040), high T stage(T3+ T4 stage)( OR=1.816 (95% CI: 1.273-2.590), P=0.001), N1b stage ( OR=1.766 (95% CI: 1.233-2.530), P=0.002), M1 stage ( OR=9.833 (95% CI: 3.190-30.309), P<0.001) and sTg level ( OR=1.035 (95% CI: 1.029-1.042), P<0.001) were risk factors for poor prognosis before PSM, while high T stage (T3+ T4 stage)( OR=1.870 (95% CI: 1.212-2.886), P=0.005), M1 stage ( OR=8.993 (95% CI: 2.434-33.225), P=0.001), sTg level ( OR=1.040 (95% CI: 1.030-1.049), P<0.001) were still risk factors, and N1b stage ( OR=1.459 (95% CI: 0.938-2.270), P=0.094), male ( OR=1.383 (95% CI: 0.912-2.096), P=0.127) were no longer risk factors for poor prognosis after PSM. ROC curve analysis showed that the cut-off value of sTg was 10.25 μg/L, with the sensitivity of 81.0%(222/274) and the specificity of 84.2%(1 181/1 403). Conclusions:After reduction of selection bias by PSM, male is no longer a risk factor for prognosis after 131I treatment of DTC. In addition, high T stage(T3+ T4 stage), M1 stage and sTg≥10.25 μg/L were risk factors for poor prognosis.
