Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective:To investigate the risk factors associated with the positive results of early postpartum depression screening.Methods:This study involved 2 889 women who were negative in prenatal depression screening and delivered in the Maternal and Child Health Hospital of Hubei Province from 1 March to 30 April 2021. The Edinburgh Postnatal Depression Scale (EPDS) score, Adaptation Partnership Growth Affection Resolve (APGAR) score, and related living habits of the enrolled subjects were investigated on the 5th to 7th day after delivery. All patients were divided into two groups with 2 354 in the negative group (EPDS score<13) and 535 in the positive group (EPDS score≥13), based on the EPDS scores at 5 to 7 days postpartum. Chi-square test, trend Chi-square test, and rank-sum test were used for univariate analysis. Risk factors associated with positive depression screening were analyzed using binary logistic regression. Results:Univariate analysis suggested that there were statistically significant differences between the two groups in maternal personality, marital relationship, family functioning, sleep quality during pregnancy, smoking and drinking habits during pregnancy, prenatal EPDS score, mode of delivery, whether or not to have intrapartum cesarean section and forceps delivery, duration of labor in vaginal delivery, the proportions of puerperae and neonates who were transferred to intensive care unit (ICU), twin pregnancy, placenta previa, abnormal fetal position, premature birth, postpartum hemorrhage, and having three or more complication (all P<0.05). Binary logistic regression analysis suggested that extravertion ( OR=0.483, 95% CI:0.369-0.632), good marital relations ( OR=0.540, 95% CI:0.422-0.691) and good sleep during pregnancy ( OR=0.340, 95% CI:0.245-0.471) were protective factors for early postpartum depression, while introversion ( OR=1.632, 95% CI:1.275-2.088), poor marital relations ( OR=3.495, 95% CI: 1.946-6.276), moderate family dysfuntion ( OR=4.038, 95% CI:2.667-6.114) and severe family dysfunction ( OR=20.234, 95% CI: 2.446-167.364), smoking ( OR=2.071, 95% CI:1.315-3.263) and drinking during pregnancy ( OR=1.924, 95% CI:1.142-3.243), twin pregnancy ( OR=2.680, 95% CI:1.435-5.005), placenta previa ( OR=2.567, 95% CI:1.316-5.009), having three or more complications ( OR=1.876, 95% CI: 1.316-2.674), forceps delivery ( OR=3.043, 95% CI:1.185-7.816), intrapartum cesarean section ( OR=1.917, 95% CI:1.232-2.982), postpartum hemorrhage ( OR=1.668, 95% CI:1.069-2.604), and postpartum ICU admission ( OR=2.601, 95% CI: 1.112-6.086) were risk factors for early postpartum depression. Conclusions:Healthy living habits, and good mood contribute to decreasing postpartum depression in pregnant women. Education for parturients with serious illness or complications should be strengthened to help develop a proper understanding of the disease.

Objective:To explore the genetic etiologies of newborn deaths.Methods:A total of 98 newborns who were recruited to the Neonatal Genome Project of the Children′s Hospital of Fudan University and died in the hospital from January 2018 to August 2020 were enrolled in this study. The genetic information and the interventions based on the genetic findings were retrospectively analyzed. T-test, Mann-Whitney U test, Chi square test and Fisher′s exact probability test were used to compare the demographic features and clinical characteristics between the patients with or without a genetic finding. Results:Among 98 newborns (55 males and 43 females), there were 63 preterm and 35 term infants, with a gestational age of (33±5) weeks, a birth weight of (2 107±975) g and the age at death of 12 (2,34) days. Sixteen (16%)patients were identified with genetic variants, including 11 with single nucleotide variants, 4 with copy number variants and 1 with both single nucleotide variant and copy number variant. The detected single nucleotide variants were spanning 12 genes, among which 3 were multiple disorders-related, 2 metabolic disorder-related, 2 hematological disorder-related, 2 respiratory disorder-related, 2 cardiovascular disorder-related and 1 skeletal disorder-related. The patients with a positive genetic finding had significant differences in the birth weight ((2 605±940) vs. (2 009±957) g, t=2.283, P=0.025), the gestational age ((36±5) vs. (33±5) weeks, t=2.131, P=0.036), the age at death ((37 (5, 69) vs. 11 (2, 29) days, Ζ=-2.245, P=0.025) and the history of asphyxia at birth (1/16 vs. 46% (38/82), P=0.002)when compared to those without a genetic finding. In addition, the genetic etiology rates of patients who were born term or with a birth weight ≥ 2 000 g were significantly higher than those who were born preterm (29% (10/35) vs. 10% (6/63), P=0.022) or with a birth weight<2 000 g (25% (13/51) vs. 7% (3/46), χ 2=5.016, P=0.025), respectively. Six cases were medically actionable based on the genetic findings and the treatments included special diet, applying specific medicine, hematopoietic stem cell transplantation and lung transplantation. Conclusions:Genetic etiologies are not rare in newborn deaths and mainly associated with metabolic disorder, multi-system disorders, hematological disorder, respiratory disorder, cardiovascular disorder and skeletal disorder. Some findings are medically actionable, based on which the specific treatments could be scheduled timely. A genetic etiology should be investigated in newborn deaths especially in those who are term birth or with a birth weight ≥2 000 g or without a history of asphyxia at birth.

Objective: To investigate the association between the frequency and filling rate of lateral canals and the sealing quality in the apical third roots of the permanent teeth with failed endodontic treatments, so as to explore the failure factors of root canal therapy. Methods: Clinical records of the permanent teeth with failed endodontic treatments were collected from the Department of Endodontics, Capital Medical University School of Stomatology during a period of 2 years. The teeth were diagnosed as chronic apical periodontitis and then undergone endodontic microsurgery. The sealing quality of the apical root canal was observed by means of periapical radiographs. The surgical treatments were performed and the resected root apices were collected. The samples were scanned by micro-computed tomography and the 3D volume rendered images of the resected root apices were reconstructed. Moreover, the frequency and the filling rate of lateral canals in the apical third roots were calculated. The potential relationship between tooth position and the presence of lateral canals was evaluated. Results: Totally 89 teeth with 89 root apices met the inclusion criteria and were included in the present study. The rate of correct-filling, underfilling and overfilling was 40% (36/89), 32% (28/89), and 28% (25/89), respectively, examined by periapical radiographs. Amongst all of the 89 samples, lateral canals were found in 44 samples. The incidence of apices with lateral canals was 49% (44/89). Furthermore, 3 out of 44 samples were fully filled with material in the lateral canals, and the rest 41 samples showed no filling materials. The filling rate of the lateral canals was 7% (3/44). However, no significant difference was detected between the tooth position and the presence of lateral canals (P>0.05). Conclusions The sealing quality of the apical third roots in permanent teeth with failed endodontic treatments was not good enough. The incidence of apices with lateral canals was high, but the filling rate of the canals was low. Further studies are needed to explore the relationship between lateral canals and the failure of endodontic treatment.

Objective To study the significance of the cerebrospinal fluid(CSF)lactate level in diagnosing neonatal bacterial meningitis(BM). Methods The CSF samples were collected from neonates admitted to Neonatal Ward of Children's Hospital of Fudan University between January 2014 and March 2015. CSF lactate and glucose con-centrations were measured with blood - gas analyzer. CSF and serum glucose levels were measured with glucometer. The enrolled neonates were divided into 2 groups based on CSF culture,CSF white blood cells(WBCs)and clinical presenta-tion:observation group(neonates with BM)and control group(neonates without BM). Statistical analysis of data was performed with Stata 12. 0. Results A total of 93 infants(16 assigned to observation group and 77 assigned to control group)met the inclusion criteria. Neonates in observation group had higher median CSF lactate level(4. 2 mmol/ L)and CSF lactate/ glucose ratio(L/ Gcsf)(2. 32 mmol/ L),than those in control group(1. 3 mmol/ L,0. 52),and there were significant differences(Z = - 6. 19,- 5. 92,all P ﹤ 0. 05). CSF glucose levels were lower in observation group(me-dian,1. 25 mmol/ L)than those in control group(median,2. 5 mmol/ L),and the difference was significant(Z = 4. 97, P ﹤ 0. 05);CSF/ serum glucose ratio(CSF/ Sglu)were lower in observation group(median,0. 44 vs 0. 81 in control group),and the difference was significant(Z = 4. 43,P ﹤ 0. 05). The optimal CSF lactate cutoff point of 2. 2 mmol/ L had a positive predictive value(PPV)of 72. 7% and negative predictive value(NPV)of 100. 0% for bacterial meningi-tis. The optimal L/ Gcsf cutoff point of 1. 24 had a PPV of 94. 1% and NPV of 100. 0% . The optimal CSF glucose cutoff point of 2. 0 mmol/ L had a PPV of 65. 0% and NPV of 95. 9% . The optimal CSF/ Sglu cutoff point of 0. 6 had a PPV of 60. 0% and a NPV of 96. 9% . Conclusion CSF lactate may be an excellent biomarker for early diagnosis of neo-natal BM.

Objective To investigate the immunological pathogenesis of immune reconstitution inflammatory syndrome (IRIS) during highly active antiretroviral therapy( HAART), in this prospective cohort study we analyzed the lymphocyte subsets, lymphocyte activation, changes in regulatory T cells, and levels of Th1 and Th2 cytokines in both IRIS and non-IRIS groups. Methods Two hundred and thirty-eight AIDS patients received HAART and participated prospective research cohort for 24 weeks follow-up. Forty-seven IRIS cases and 191 non-IRIS cases were enrolled in the IRIS group or non-IRIS group respectively. Blood samples were collected in both groups at pre- and post-HAART 12 weeks, 24 weeks. Using flow cytometer to detect the immunophenotypes of lymphocyte subsets (CD4 + CD45RA+ CD62L+, CD8+ CD45RA+ CD62L+naive T cells; CD4+ CD45RO+, CD8+ CD45RO+ memory T cells), activated T lymphocytes (CD4+CD38 +, CD8 + CD38 + cells), and regulatory T cell ( CD4 + CD25 + Foxp3 + ). Blood samples collected at pre-and post-HAART4 weeks, 12 weeks, 24 weeks and used ELISA to detect IL-2, IFN-γ, IL-4, IL-10and IL-7 cytokine serum levels. Results The percentages of CD4 + and CD8 + naive T cells and mlemory T cells exhibited no significant differences at the baseline, 12 weeks, 24 weeks of HAART initiation between both groups, but CD4 + and CD8 + memory T cells were demonstrated a trend towards to increase while compared to baseline during HAART. The percentages of CD4 + and CD8 + activated T cells are significantly higher at the baseline while compared to normal control and demonstrated a downward trend, but between both groups showed no significant difference. The percentages of CD4 + regulatory T cell was lower in IRIS group than non-IRIS group at the baseline, 12 weeks, 24 weeks and the onset of IRIS. Th1 cytokines, IL-2 and IFN-γshowed an upward trend during HAART at the levels of IRIS group had significantly increased at 4 weeks and the onset of IRIS. Th2 cytokines, IL-4 and IL-10 showed a downward trend during HAART,and the levels of IL-10 in IRIS group had significantly decreased at 4 weeks and the onset of IRIS. IL-7 was higher than normal control at the baseline in two groups and showed a downward trend during HAART. The level of IL-7 was higher than non-IRIS group at all follow-up points. Conclusion Memory T cells appear rapid increase in the early stage of HAART and may play a significant role in the inflammatory response of IRIS. CD4 + and CD8 + naive T cells, memory T cells and activated T cells showed no significant difference between IRIS and non-IRIS group within 24 weeks after HAART started. There was a significant reduction in the frequency of regulatory T cells in IRIS group without obvious upward trend during HAART, suggesting that the immune suppression function of regulatory T cells in IRIS was impaired. IL-2 and IFN-γ significantly increased while IL-10 significantly decreased at 4 weeks post-HAART initiation and onset of IRIS in IRISgroup than non-IRIS group, suggested that IRIS was related to cytokines environment disorder. That is, a significant increase in inflammatory cytokines, while the relative lack of non-inflammatory cytokines. The level of IL-7 decreased gradually after HAART started, and it was higher in IRIS group when compared to non-IRIS group in the first 24 weeks after HAART started. Also IL-7 may play a role in the pathogenesis of IRIS.

Objective To evaluate the effects of fluid resuscitation and large-volume hemofiltration (HVHF) on the Alveolar-arterial oxygen exchange in patients with refractory septic shock. Method A total of 89 intensive care patients with refractory septic shock treated with fluid resuscitation and/or HVHF were enrolled between August 2006 and December 2009. All the patients were randomly divided into two groups. In group A, patients were treated with fluid resuscitation, n = 41 cases) and in group B, patients were treated with large-volume hemofiltration and fluid resuscitation, n =48). The O2 content of central venous blood(CcvO2), arterial oxygen content (CaO2), Alveolar-arterial oxygen pressure difference (P(A-a)DO2), the ratio of arterial oxygen pressure/alveolar oxygen pressure (PaO2/PAO2), respiratory index (RI) and oxygenation index (OI) were checked. The levels of oxygen exchange in two groups were detected by arterial blood gas analysis before treatnent, 24 hour, 72 hour and 7 days after treatment. The APACHE Ⅱ scores in patients with refractory septic shock were measured before and the 7th day after treatment with HVHF and/or fluid resuscitation respectively. Data were analyzed by using t -test and chi-square test to compare the differences and ratio between two groups and were expressed in mean ± standard deviation, and the analysis of variance was done with SPSS version 12.0 software. Results ① The differences in CcvO2 and CaO2 between two groups were[(0.60±0.24) vs. (0.72±-0.28), P ＜0.05 and (0.84±0.43) vs. (0.94±0.46), P ＜0.05]; and the oxygen extraction rates (O2ER) were significantly different between two groups [(28.7±2.4) vs. (21.7±3.4), P<0.01];② The levels of P(A-a)DO2、ratio of PaO2/PAO2、RI and OI in group B were reduced more significantly than in group A (P<0.05 or P<0.01);③The APACHE Ⅱ scores in both groups were gradually reduced after treatment for 7 days, and the APACHE Ⅱscore in group B on the 7th day of treatment were lower than that in group A[(17.2 ± 6.8) vs. (8.2 ± 3.8), P ＜ 0.01]. Conclusions Fluid resuscitation and HVHF could improve alveolar-arterial-oxygen exchange in patients with refractory septic shock, and at the same time decreased the APACHE Ⅱ scores, improving the survival rate of patients.

Objective:To elucidate action mechanism of δ-tocotrienol in inducing apoptosis of human hepatoma HepG2 cells. Methods:Cell proliferation and viability were assessed by MTT assay; cell cycle distribution, apoptotic rate and mitochondrial membrane potential were measured by using high content screening system; the expression of apoptosis-related protein such as caspase-3, caspase-8, caspase-9, Bcl-2, Bax, tBid and cytochrome C in the HepG2 cells were evaluated by Western blotting. Results:δ-Toco-trienol inhibited HepG2 cell proliferation and induced apoptosis in a dose-dependent manner. This growth-inhibiting effect of δ-toco-trienol correlated with loss of mitochondrial membrane potential and release of cytochrome C from mitochondria to cytoplasm, and regulation of the protein expression of Bcl-2 family members, such as up-regulation of Bax and tBid and down-regulation of Bcl-2. Subsequently tocotrienol induced the activation of caspase-3, caspase-8, and caspase-9 which finally induced apoptosis of hepatoma HepG2 cells. Conclusion:δ-Tocotrienol induced apoptosis of human hepatoma HepG2 cells via mitochondrial pathway and membrane death receptor pathway.

Objective To study the therapeutic effects of omeprazoie in high-dose given by continuous intravenous infusion in the treatment of stress-related mucosal injury of G-I tract in intensive care patients.Method Totally 98 intensive care patients with stress-related mucosal injury(SRMI)were enrolled from August 2006 to October 2008 Department in Intensive Care Unit(ICU)of the Provincial Hospital Affiliated to Shandong University.All the patients were randomly divided into high-dose omeprazoie group(group A)and control group(group B).In group A,omeprazoie was administrated in loading dose of 80 mg Ⅰ.Ⅴ.in 5 minutes followed by maintenance dose of 8.0 mg/h intravenous infusion for 72 hours,while in group B,omeprazoie was given in dose of 40mg/8h intravenous infusion for 72 hours.The pH value of gastric juice was determined by German Roche pH test paper every 2 to 8 hours in the patients of both groups.The coffee like or red juice in the gastrointestine decompressor was observed.At the same time,hemoglobin(HB)was detected by Automatic blood cell analyzer Sysmex XE-2100,blood urea nitrogen(BUN)was determined by Automatic Analyzer Au5400,and buffer excess(BE)was checked by GEM Premie arterial blood gas analyzer in all patients.Data were expressed as mean ± standard deviation(x-± s)and the analysis of variance was done with SPSS 12.0 software.Comparison of mean value between two groups was conducted with t-test and the ratio was calculated by using chi-square test(X2 test).The change was considered as statistically significant if P value was less than 0.05.Results Four,eight,and 24 hours after treatment with omeprazole,the pH values in patients of group A were higher than those in patients of group B(four hous:6.63 ±0.62 vs.3.14 ±0.26,P＜0.01;eight hours and 24 hours:P＜0.05 or P＜0.01).At 8 hours and 24 hours after treatment,the HB was higher,BUN and BE were lower in group A than those in group B(P＜0.03 or P＜0.01).The total rate of hemostasis of upper G-I tract bleeding in group A was higher than that in group B(95.35%vs.78.19%,P＜0.05).Conclusions For treating the intensive care patients with SRMI,the continues intravenous infusion of omeprazole inhigh dose is superior to conventional dosage.
