ABSTRACT

OBJECTIVE@#To investigate the toxicity management and efficacy evaluation of BCMA-chimeric antigen receptor T cells(CART) in the treatment of relapsed and refractory multiple myeloma (MM).@*METHODS@#The efficacy and adverse reactions of 21 patients with MM who received BCMA-CART treatment at the First Affiliated Hospital of Wenzhou Medical University from December 2017 to September 2020 were evaluated, and the efficacy assessment and survival analysis for high-risk patients and non-high-risk patients were evaluated.@*RESULTS@#After infusion of BCMA-CART cells in 21 MM patients, the number of effective cases was 17, of which the complete remission (sCR/CR) was 10, and the partial remission (VGPR/PR) was 7. The median OS time for all patients was 19.4 months, and the median PFS time was 7.9 months. The number of patients with extramedullary disease(EMD), high-risk genetics, and ISS stage Ⅲ were 5, 15 and 8, and the effective number was 3, 11 and 6, respectively. The treatment of 3 patients without high-risk factors was effective. The median OS and median PFS of patients with EMD were 14.2 and 2.5 months, respectively, which were shorter than those of patients without EMD (19.4 months and 8.9 months, respectively). The median OS and median PFS of patients with high-risk cytogenetic factors and ISS Ⅲ were not significantly different from those of non-high-risk patients. Cytokine release syndrane (CRS) occurred in 20 patients, of which 14 cases were Grade 1 CRS, while 6 were Grade 2, no CRS of Grade 3 or above occurred. IL-6 receptor inhibitors were used in 9 patients. All CRS were controlled effectively, and no patients had neurological toxicity.@*CONCLUSION@#BCMA-CART is a certain curative effect in the treatment of relapsed and refractory multiple myeloma, and the adverse reactions can be well controlled through close monitoring and timely treatment.

ABSTRACT

OBJECTIVES@#To study the significance of interleukin-6 (IL-6) and interleukin-27 (IL-27) in the differential diagnosis of acute respiratory distress syndrome (ARDS) and neonatal respiratory distress syndrome (NRDS) in preterm infants.@*METHODS@#The preterm infants with the manifestation of respiratory distress who were treated in the Neonatal Diagnosis and Treatment Center, Children's Hospital of Chongqing Medical University, from March to November 2021, were enrolled in this prospective study. According to the diagnosis results, they were divided into two groups: ARDS group (n=18) and NRDS group (n=20). ELISA was used to measure the plasma levels of IL-6 and IL-27. The receiver operating characteristic (ROC) curve was used to analyze the value of each index in the diagnosis of ARDS.@*RESULTS@#The ARDS group had significantly higher plasma levels of IL-6 and IL-27 than the NRDS group (P<0.05). The ROC curve analysis showed that IL-6 had an area under the ROC curve (AUC) of 0.867 for the diagnosis of ARDS, with a sensitivity of 61.1% and a specificity of 95.0% at the cut-off value of 56.21 pg/mL. The ROC curve analysis also showed that IL-27 had an AUC of 0.881 for the diagnosis of ARDS, with a sensitivity of 83.3% and a specificity of 80.0% at the cut-off value of 135.8 pg/mL.@*CONCLUSIONS@#Plasma IL-6 and IL-27 can be used as biological indicators for early differential diagnosis of ARDS and NRDS in preterm infants.

ABSTRACT

OBJECTIVE@#To investigate the effect of internal external fixator assisted O-arm navigation imaging in the treatment of unstable pelvic fractures.@*METHODS@#From May 2019 to November 2019, 15 patients with unstable pelvic fractures were treated by intraoperative O-arm navigation imaging using INFIX technology. There were 6 males and 9 females. The age ranged from 24 to 66 years old. The course of disease ranged from 2 to 14 days. According to Tile classification, there were 1 case of B1 type, 8 cases of B2 type, 3 cases of C1 type, and 3 cases of C2 type. According to Young-Burgess classification, there were 8 cases of LC, 1 case of APC, 4 cases of VS, 2 cases of CM. Preoperative routine pelvic anteroposterior film, entrance position, exit position and pelvic CT three-dimensional reconstruction were performed. Intraoperative O-arm navigation system three-dimensional reconstruction and triplane scanning imaging were used to evaluate the effect of intraoperative reduction. The anterior pelvic ring was fixed with internal external fixator, and the posterior ring was fixed with sacroiliac screw, plate screw or lumbar iliac screw. The operation time, intraoperative bleeding and nail placement were observed and recorded. The quality of fracture reduction was evaluated by Matta standard, and the postoperative function was evaluated by Majeed function score.@*RESULTS@#Wound healing was good in all patients without vascular, nerve and local irritation complications. All the 15 patients were followed up for 10 to 16 months. The fracture reduction was evaluated according to the Matta scoring standard, 9 cases were excellent results, 5 cases were good, and 1 case was medium. The Majeed functional score was 0 to 95 points.@*CONCLUSION@#The built-in external fixator assisted O-arm navigation imaging system in the treatment of unstable pelvic fractures. The reduction effect is evaluated in advance, the operation time is shortened, and the accuracy of internal fixation is improved. The operation is simple, safe and less bleeding. The operation is in line with the principles of minimally invasive medical treatment and precision medical treatment in orthopedics, which is conducive to the recovery of patients' postoperative function and rapid recovery.

ABSTRACT

JC virus (JCV) is a member of polyomaviridae family that infects approximately 70% of the population worldwide. JCV constantly stays in a latent state after the primary infection. In immunosuppressed individuals, especially under the circumstances of low cellular immune function, JCV may be reactivated and lead to severe clinical manifestations. In recent years, the correlation between JCV and complications after renal transplantation has captivated widespread attention. JCV-associated nephropathy (JCVAN) has been reported. Here, latest research progresses on the epidemiology, molecular biology, in vivo infection process, JCV and complications after renal transplantation, and the relationship between JCV and BKV were reviewed, aiming to provide reference for the adjustment of immunosuppressive regimen following renal transplantation.

ABSTRACT

Objective:To analyze the epidemiological characteristics of a family and workplace clustering of COVID-19, identify the source of infection and the transmission chain, and provide evidence for prevention and control of COVID-19 pandemic. Method:Field epidemiological method was used to conduct the investigation of confirmed cases and close contacts in this cluster. Data were analyzed with descriptive method. Real-time fluorescent quantitative PCR (RT-PCR) was used to detect the novel coronavirus nucleic acid in the collected respiratory tract samples. Results:A total of 18 epidemiological related cases were collected including 16 confirmed cases and 2 cases of asymptomatic infections. The involved places included 1 beauty clinic workplace and 3 families. Seven cases were males and 11 cases were females, with the minimum, maximum and median age of 3, 65 and 32 years old, respectively. Among them, the employees attack rate was 9.80% (10/102), the family attack rate was 7.70% (5/78), and the customer attack rate was 0.58% (1/173). Positive nucleic acid test result in the respiratory tract sample of asymptomatic infection lasted for more than 2 months. Conclusions:The cause of this clustered COVID-19 epidemic is that the workplace environment is relatively closed with clustering crowds, and the source of imported infection is not discovered in time, which lead to a point-source outbreak and spread through family close contacts and clustering.

ABSTRACT

Cardio-cerebrovascular disease (CCVD) is a major comorbidity of Coronavirus disease 2019 (COVID-19). However, the clinical characteristics and outcomes remain unclear. In this study, 102 cases of COVID-19 from January 22, 2020 to March 26, 2020 in Xixi Hospital of Hangzhou were included. Twenty cases had pre-existing CCVD. Results showed that compared with non-CCVD patients, those with CCVD are more likely to develop severe disease (15% versus 1%), and the proportion of pneumonia severity index grade IV was significantly higher (25% versus 3.6%). Computed tomography images demonstrated that the proportion of multiple lobe lesion involvement was significantly higher in the CCVD group than in the non-CCVD group (90% versus 63.4%). Compared with non-CCVD group, the levels of C-reactive protein, fibrinogen, D-dimer, and serum amyloid-A were higher, whereas the total protein and arterial partial PaO

ABSTRACT

OBJECTIVE@#To understand the characteristics of patients with mimicking specificity autoantibodies through the analysis of the causes of autoantibodies, specificity of antibodies, strategy of blood transfusion, effect of transfusion and distribution of antibodies in China and abroad.@*METHODS@#A total of 23 patients who applied for blood in our hospital from January 2017 to June 2019 were identified as mimicking specificity autoantibodies by antibody identification or absorption-elution test. The causes of mimicking specificity autoantibodies, antibody specificity, blood transfusion strategy and blood transfusion effect were analyzed. The relevant articles on antibodies published in China and abroad were summarized and sorted out, and the distribution of antibodies was analyzed.@*RESULTS@#All the 23 patients with mimicking specificity autoantibodies were Rh blood group system antibodies, of which mimicking anti-Ce autoantibodies were the most common (34.8%), followed by mimicking anti-e autoantibodies (26.1%), mimicking anti-D autoantibodies (21.7%), mimicking anti-C autoantibodies (8.7%) and mimicking anti-E autoantibodies (8.7%). Except for 2 cases with suspected history of blood transfusion, the other 21 cases had a history of blood transfusion / pregnancy. The most common cause of mimicking autoantibodies was drug, followed by infection and autoimmune diseases. The hemoglobin (Hb) of pretransfusion in the blood transfusion group was (48.4±23.9) g/L, which was significantly lower than (86.0±38.9) g/L in the non-transfusion group (P<0.01). Except for 2 cases who could not evaluate the effect of blood transfusion, the effective rate of transfusion was 100%. According to the retrospective statistics of 32 related articles published in China and abroad, the most type of mimicking antibodies were in Rh blood group system, accounting for 79.28%, among which anti-E was the main part of all mimicking autoantibodies, accounting for 21.95%. The following ones were in Kidd system MNSs system, and Kell system.@*CONCLUSION@#Combined with the clinical symptoms and the degree of difficulty of blood matching, the best strategy of blood transfusion should be selected to ensure the safety of blood transfusion.

ABSTRACT

This study investigated the protective effect of total triterpenoids from Chaenomeles speciosa against Helicobacter pylori(Hp)-induced gastritis in mice and explored its possible mechanism. The chronic atrophic gastritis(CAG) model mice were randomly divided into four groups of model, total triterpenoids from C. speciosa(50 and 100 mg·kg~(-1)) and triple therapy, with C57 BL/6 J mice without Hp infection taken as the normal group. Mice in the treatment groups were given corresponding drugs once a day for 4 weeks. Then the following indexes were detected: the contents of reactive oxygen species(ROS), monocyte chemotactic protein 1(MCP-1), keratinocyte chemokines(KC), TNF-α, IL-1β, IL-6, IL-18, IL-4 and IL-10 in blood and gastric tissue, the activities and contents of LDH, MPO, SOD, GSH-Px, CAT and MDA in gastric tissue and the activities of β-glucuronidase, β-galactosidase, cathepsins B and D in blood, gastric tissue and lysosome. Besides, the mRNA expression levels of Toll-like receptor 4(TLR4), myeloid differentiation factor 88(MyD88), Bcl-2, Bcl-xl, Bax and Bad in gastric tissue were determined by quantitative real-time PCR. Western blot was employed to detect the protein expression levels of TLR4, MyD88, p-IKKβ, p-IκBα, NOD-like receptor 3(NLRP3), apoptosis-associated speck-like protein(ASC), pro-caspase-1, caspase-1, thioredoxin-interacting protein(TXNIP), pro-IL-1β, pro-IL-18, Bcl-2, Bcl-xl, Bax, Bad, cytochrome C, apoptotic protease-activating factor-1(Apaf-1), pro-caspase-9, pro-caspase-3, cleaved-caspase-9, cleaved-caspase-3, poly(ADP-ribose) polymerase 1(PARP-1), cleaved-PARP-1 and cytosol and nucleus NF-κB p65 in gastric tissue. The results indicated that the total triterpenoids from C. speciosa significantly suppressed Hp proliferation, alleviated the damage to gastric mucosa and improved lymphocyte infiltration and gland atrophy. They were also effective in reducing the activities of β-glucuronidase, β-galactosidase, cathepsins B and D in blood and gastric tissue, elevating the activities of β-glucuronidase and cathepsin D in lysosomal organelles, decreasing the contents of ROS, MCP-1, KC, TNF-α, IL-1β, IL-6, IL-18 in blood, MDA content and MPO and LDH activities in gastric tissue and increasing the contents of IL-4 and IL-10 in blood and activities of SOD, CAT and GSH-Px in gastric tissue. Other phenomena were also observed after the treatment with total triterpenoids from C. speciosa, including the down-regulation of the mRNA and protein expression levels of TLR4, MyD88, Bax and Bad, the protein expression levels of p-IKKβ, p-IκBα, NLRP3, ASC, pro-caspase-1, caspase-1, TXNIP, pro-IL-1β, pro-IL-18, cytochrome C, Apaf-1, cleaved-caspase-9, cleaved-caspase-3, cleaved-PARP-1 and nuclear NF-κB p65, reduction of p-IKKβ/IKKβ and p-IκBα/IκBα ratios and up-regulation of the mRNA and protein expression levels of Bcl-2 and Bcl-xl, up-regulation of pro-caspase-9, pro-caspace-3, cytosol NF-κB p65 protein expression levels and Bcl-2/Bax and Bcl-xl/Bad ratios in gastric tissue. These aforementioned results suggest that the total triterpenoids from C. speciosa have significant protective effects against CAG induced by Hp, and its mechanism may be related to enhancing the function of endogenous antioxidant system, suppressing the oxidative stress and inflammatory reaction induced by Hp, correcting lysosomal dysfunction and inflammatory activation of TLR4/NF-κB/NLRP3 inflammasome signaling pathway and thus inhibiting mitochondria-mediated apoptosis.

ABSTRACT

Coptidis Rhizoma, as a bulk medicinal material, is in great demand in clinical practice. Its quality is uneven in the market due to the mixture of genuine, counterfeit and adulterants. Therefore, it is particularly important to establish a quality control system for Coptidis Rhizoma. Based on the concept of Chinese medicine quality marker(Q-marker), the potential quality markers of Coptidis Rhizoma were analyzed and predicted from the perspective of chemistry and pharmacology. The sources of the Q-markers of Coptidis Rhizoma were identified by literature retrieval. The potential Q-markers were then screened through the visualization of the "components-targets-pathways" network. High performance liquid chromatography(HPLC) was used to establish a multi-indicator qualitative and quantitative control method featuring fingerprints for 10 batches of Coptidis Rhizoma. A supervised mode of orthogonality partial least squares method-discriminant analysis(OPLS-DA) was used to screen the main marker components that caused differences between groups. The literature review results showed that the alkaloids were the main source of Coptidis Rhizoma Q-markers.The fingerprints of 13 common peaks were successfully established, and berberine, palmatine, berberine and epiberberine were selected as Q-markers of Coptidis Rhizoma, and their contents were determined.Based on the concept of the Q-marker of traditional Chinese medicine, the four components can be selected as the Q-marker of Coptidis Rhizoma after comprehensive consideration. The results of this study are not only conducive to the quality evaluation of Coptidis Rhizoma on the market, but also provide a reference for the overall quality control of Coptidis Rhizoma and lay foundation for the future exploration of the mechanism of Coptidis Rhizoma.

ABSTRACT

Objective:To examine the survival status and explore factors related to death among human immunodeficiency virus (HIV) infected patients receiving antiretroviral therapy (ART) in Taizhou City during 2006‒2019. Methods:A retrospective cohort study was conducted to analyze the data on HIV-infected patients receiving ART in Taizhou during 2006‒2019. Kaplan-Meier (K-M) method was used to calculate the cumulative survival rate and cumulative treatment success rate. Cox regression model was used to determine survival status and factors associated with ART. Results:A total of 2 904 HIV-infected patients was included. The cumulative survival rate after 1, 3, 5, and 8 years of ART were 96.9%, 94.9%, 93.1% and 92.1%, respectively, and the cumulative treatment response rate were 91.3%, 85.3%, 81.8% and 73.8%, respectively. Compared with aged 18-30 years old, baseline CD4+T cell >350 count/μL, normal hemoglobin level, effective ART, no clinical symptom at baseline, and homosexual transmission, we found that aged 51-60 years old(HR=4.94,95%CI:1.66-14.69), aged over 60 years old(HR=9.14,95%CI:3.14-26.63), anemia at baseline(HR=2.24,95%CI:1.55-3.23), baseline CD4+T cell <200 count/μL(HR=4.35,95%CI:2.14-8.86), ART failure (HR=3.90,95%CI:2.73-5.58), heterosexual transmission(HR=1.92,95%CI:1.15-3.20), and signs of symptom at baseline(HR=1.68,95%CI:1.16-2.41) were risk factors of HIV-related death. Conclusion:The effect of ART in Taizhou City is confirmed with a high cumulative survival rate and treatment success. We should pay additional attention to senior HIV-infected patients with anemia at baseline and intensively monitor the effect of ART. Interventions such as “treat after discover” are supposed to be implemented more widely to further reduce HIV-related mortality.

ABSTRACT

Intravenous immunoglobulin (IVIG) is an immunoglobulin (Ig) isolated from the plasma of healthy human, and its main component is IgG. The mechanism of IVIG is complex, which may play a role via multiple pathways. For example, the combination of Fc fragment of IgG with various Fc gamma receptor (FcγR) regulates inflammatory response and autoantibody metabolism, and Fab fragment of IgG neutralizes multiple antigens and other molecules. IVIG may also inhibit complement activation and affect the balance of anti-inflammation and proinflammation among immune cells. In the treatment of diseases, IVIG constantly plays a role through multiple mechanisms simultaneously, primarily via one certain mechanism in different diseases. IVIG is commonly applied in the desensitization treatment of sensitized patients, ABO incompatible renal transplantation, antibody-mediated rejection and several infectious diseases. In this article, the mechanism of IVIG and its application in renal transplantation were reviewed.

ABSTRACT

There were three new blood group systems including the KANNO blood group system, the Sid blood group system and the CTL2 blood group system (provisional status), have been registered by the International Society of Blood Transfusion (ISBT) registered Science August 2019. The main reason for this update is that the significant SNPs of the KANNO blood group system (rs1800014) and the Sid blood group system (rs7224888) have been found through genome-wide association studies and whole exome sequencing. The new genetic evidences are consistent with the current immunological findings. In addition, although CTL2 antigen has been found on erythrocyte ghost (erythrocyte membrane) since 2017, CTL2 blood group system is still in provisional status due to lack of serological and genetic evidence. In this review, the experimental research advances of these three ISBT blood group systems and discuss the clinical value of the relevant researches was summarized briefly.

ABSTRACT

OBJECTIVE Since the coronavirus disease 2019 (COVID-19) outbreak in December 2019, the search for a potential treatment for COVID-19 has been a constant focus. Therefore, we identified potential treatments for COVID-19 from Hippophae Fructus, a Tibetan medicine that may act on COVID-19, using a network pharmacology approach. METHODS We collected the chemical constituents and corresponding targets of Hippophae Fructus from traditional Chinese medicine system pharmacology (TCMSP). COVID-19 related genes were predicted in pubmed-Gene, OMIM and GeneCards databases. Then, protein-protein interactions (PPIs) of key genes were analyzed by STRING database. Compound-target-diseases network was constructed using Cytoscape software. The potential pathways were deter?mined by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. Additionally, molecular docking was used to verify the binding effect between the active component and the target. RESULTS A total of 33 components and 192 corresponding targets in Hippophae Fructus were found. 50 genes were obtained from the intersection of component targets and disease targets. These genes include IL-6, TNF, MAPK8 and PTGS2, which regu?late several pathways associated with COVID-19, involving Hepatitis B, Influenza A, TNF signaling pathway and Tuber?culosis. More importantly, high-node compounds such as quercetin and beta-sitosterol can well bind to key targets. CONCLUSION Some components in Hippophae Fructus can act on COVID-19 related genes and regulate multiple pathways. Perhaps Hippophae Fructus has the effect in treating COVID-19.

ABSTRACT

Objective:To explore an efficient method of practical teaching for ultrasonography.Methods:There were 41 five-year clinical medical students intending to learn ultrasonography in the spring semester of 2019. After completing common theory courses, they were divided into two groups randomly for practice courses, which consisted of two modules: Lecture and Hands-on. Lecture included case-based learning while Hands-on included pictures reading. Each group followed different sequence of modules. There were assessments of ultrasound theory, practice or the combination of both before, during and after practice courses.Results:The theory and practice ability of each group improved significantly after practice courses ( P < 0.05). Moreover, the group whose Hands-on module preceded Lecture module got the higher scores in the evaluation of the combined ability of theory and practice ( P < 0.05). Conclusion:The theory was as important as the practice during the clerkship of ultrasonography. The clinical practical teaching pattern that Hands-on precedes Lecture has achieved better teaching effects.

ABSTRACT

Objective:To observe the clinical efficacy of modified Huanglian Wendantang and Shaofu Zhuyutang in the treatment of ovulation disorder in patients with polycystic ovary syndrome (PCOS) due to the combined phlegm and stasis-induced and its influence on chronic inflammation. Method:According to the random number table, 100 patients were divided into a control group (50 cases) and an observation group (50 cases). Apart from lifestyle intervention and oral administration of clomiphene citrate (CC) capsules to induce ovulation, patients in the control group further received Guizhi Fulingwan, 6 g/time, 2 times/day, while those in the observation group were treated with the modified Huanglian Wendantang and Shaofu Zhuyutang, 1 dose/day, for six menstrual cycles. The ovulation, endometrial thickness, proportion of type A endometrium, as well as the pulsatility index (PI) and resistance index (RI) of uterine artery were monitored before and after treatment. The fasting blood glucose (FBG), fasting insulin (FINS), luteinizing hormone (LH), follicle stimulating hormone (FSH), serum testosterone (T), estradiol (E<sub>2</sub>), dehydroepiandrosterone sulfate (DHEAS), tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), high-sensitivity C-reactive protein (hs-CRP), adiponectin (APN), and interleukin-6 (IL-6) levels before and after treatment were detected, followed by the calculation of homeostasis model assessment-insulin resistance (HOMA-IR) value and the evaluation of ovarian volume and combined phlegm and stasis-induced syndrome score. Result:The overall response rate of the observation group was (44/47) 93.62%, which was higher than (36/46) 78.26% of the control group (<italic>χ</italic><sup>2</sup>=4.802, <italic>P</italic><0.05). The ovulation rate in the observation group was (199/264) 75.38%, higher than (173/272) 63.60% in the control group (<italic>χ</italic><sup>2</sup>=8.714, <italic>P</italic><0.01). The clinical pregnancy rate of the observation group was (11/47) 23.40%, higher than (5/46) 10.87% of the control group, but the difference was not statistically significant (<italic>χ</italic><sup>2</sup>=2.564, <italic>P</italic>>0.05). Compared with the control group, the observation group exhibited reduced PI, RI, LH, T, DHEAS, FINS, FPG, HOMA-IR, TNF-<italic>α</italic>, hs-CRP, and IL-6 (<italic>P</italic><0.01), but elevated E<sub>2</sub>, FSH, and APN (<italic>P</italic><0.01). Besides, the bilateral ovarian volume and combined phlegm and stasis-induced syndrome score of the observation group were smaller than those of the control group (<italic>P</italic><0.01), while the endometrial thickness and proportion of type A endometrium were higher (<italic>P</italic><0.01). Conclusion:On the basis of CC treatment, the modified Huanglian Wendantang and Shaofu Zhuyutang alleviates the ovulation disorder in PCOS patients of combined phlegm and stasis-induced syndrome and regulates IR and chronic inflammation, thus creating a favorable condition for clinical pregnancy, which is worthy of further research.

ABSTRACT

Objective:To observe the clinical efficacy of modified Xiaoyao Erxian decoction in the treatment of mood disorders among perimenopausal syndrome due to kidney deficiency and liver depression and its effects on monoamine neurotransmitters and brain-derived neurotrophic factor (BDNF). Method:According to the random number table, 108 patients were divided into a control group (54 cases) and an observation group (54 cases). Control group were treated with Shugan Jieyu capsule orally, two capsules per time, two times per day, while those in the observation group received the modified Xiaoyao Erxian decoction, one bag per day, for 12 consecutive weeks. Before and after treatment, the Hamilton Anxiety Scale (HAMA), 17-item Hamilton Depression Rating Scale (HAMD-17), modified Kupperman Index (KI), Pittsburgh Sleep Quality Index (PSQI), Menopause-specific Quality of Life (MENQOL) and kidney deficiency and liver depression syndrome scores were calculated. The levels of estradiol (E<sub>2</sub>), follicle-stimulating hormone (FSH), luteinizing hormone (LH), BDNF, 5-hydroxytryptamine (5-HT), norepinephrine (NE), and dopamine (DA) were detected, followed by safety evaluation. Result:The HAMA, HAMD-17, KI, kidney deficiency and liver depression syndrome, PSQI, and MENQOL scores of the observation group were lower than those of the control group (<italic>P</italic><0.01), whereas the 5-HT, E<sub>2</sub>, DA, NE, and BDNF levels in the observation group were higher (<italic>P</italic><0.01). The clinical efficacy of the observation group was superior to that in the control group (<italic>Z</italic>=2.184, <italic>P</italic><0.05). No adverse reactions occurred after the oral administration of Chinese medicinal preparations. Conclusion:The modified Xiaoyao Erxian decoction effectively alleviates the mood disorders and other related symptoms of perimenopausal syndrome due to kidney deficiency and liver depression by regulating the monoamine neurotransmitters, BDNF, and E<sub>2</sub>, without inducing obvious side effects.
