Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Objective To compare the difference and consistency between OPD-Scan Ⅲ and IOL-Master 700 in the measurement of corneal curvature(flat keratometry,K1 and steep keratometry,K2)and horizontal corneal diameter(white-to-white(WTW)distance).Methods Totally 268 patients with 328 eyes(164 right eyes and 164 left eyes)who underwent cataract surgery at the Department of Ophthalmology of the Aerospace Centre Hospital from October 2021 to September 2022 were selected for this study.The K1,K2,and WTW values of the sampled right or left eyes were measured and analyzed using OPD-Scan Ⅲ and IOL-Master 700,respectively.Parameter comparisons were performed through paired t-tests;correlations between parameters were detected through the Pearson correlation analysis;and the Bland-Altman method and intragroup correlation coefficient(ICC)analysis were employed to determine the consistency of parameter measurements between the two instruments.Results The K1 and K2 values measured by OPD-Scan Ⅲ were greater than those measured by IOL-Master 700,while the WTW values were lower than those measured by IOL-Master 700,but the differences were statistically significant(all P＜0.001).K1,K2,and WTW values measured by OPD-Scan Ⅲ were positive-ly correlated with the corresponding values measured by IOL-Master 700,and the differences were statistically significant(all P＜0.001).The proportions of K1,K2,and WTW values outside the 95％limits of agreement for both instruments were within 5％,but the absolute value of the difference in values within the 95％limits of agreement was close to or more than(1.0)D,indicating a sizeable clinical deviation.ICC analysis confirmed a good consistency between K1 and K2 values of the left and right eyes measured by the two instruments(ICC＞0.90).The difference in WTW values measured by the two instruments was significantly correlated with K2 values(both P＜0.05).There were 5 samples(83.33％)outside the positive deviation range of WTW values,of which K2 measured by IOL-Master 700 was above 47.03.Conclusion The OPD-Scan Ⅲ and IOL-Master 700 have been found to have measurement biases when assessing K1,K2 and WTW.In clini-cal practice,the two instruments cannot be interchanged as an alternative to each other.The WTW values measured by IOL-Master 700 are greater than those obtained by OPD-Scan Ⅲ;when K2≥47.03,the WTW values may not be reliably ref-errable.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To report a Chinese pedigree with autosomal dominant Waardenburg syndrome, and to identify causative gene mutations.Methods:Clinical data and peripheral blood samples were collected from the proband and her parents. Genomic DNA was extracted, gene mutations were detected through a next-generation skin-targeted sequencing panel, and Sanger sequencing was performed to verify causative mutations.Results:The proband clinically presented with irregular white patches on the abdomen and lower limbs, moderate to severe sensorineural deafness in the right ear, and iris heterochromia in both eyes. The proband′s mother presented with iris heterochromia in both eyes, epicanthus, early canities and thick eyebrows. In the family, both the proband and her mother were diagnosed with Waardenburg syndrome. A causative frameshift mutation c.976-977delinsT (p.Thr327Profs*54) was identified in both the proband and her mother, which caused the AG to TT base substitution at positions 976 - 977 in the coding region of exon 7 of the PAX3 gene, resulted in a frameshift from the amino acid position 327 to 54 in the PAX3 protein (threonine was substituted by proline at amino acid position 327). The proband′s father showed a normal phenotype, and his genetic test results were negative.Conclusion:The novel frameshift mutation c.976-977delinsT (p.Thr327Profs*54) in the PAX3 gene may contribute to the clinical phenotype of the patients with Waardenburg syndrome in the family.

The present study focused on the potential mechanism of betulin (BT), a pentacyclic triterpenoid isolated from the bark of white birch (Betula pubescens), against chronic alcohol-induced lipid accumulation and metaflammation. AML-12 and RAW 264.7 cells were administered ethanol (EtOH), lipopolysaccharide (LPS) or BT. Male C57BL/6 mice were fed Lieber-DeCarli liquid diets containing 5% EtOH for 4 weeks, followed by single EtOH gavage on the last day and simultaneous treatment with BT (20 or 50 mg/ kg) by oral gavage once per day. In vitro, MTT showed that 0-25 mM EtOH and 0-25 μM BT had no toxic effect on AML-12 cells. BT could regulate sterolregulatory-element-binding protein 1 (SREBP1), lipin1/2, P2X7 receptor (P2X7r) and NOD-like receptor family, pyrin domains-containing protein 3 (NLRP3) expressions again EtOH-stimulation. Oil Red O staining also indicated that BT significantly reduced lipid accumulation in EtOH-stimulated AML-12 cells. Lipin1/2 deficiency indicated that BT might mediate lipin1/2 to regulate SREBP1 and P2X7r expression and further alleviate lipid accumulation and inflammation. In vivo, BT significantly alleviated histopathological changes, reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and triglyceride (TG) levels, and regulated lipin1/2, SREBP1, peroxisome proliferator activated receptor α/γ (PPARα/γ) and PGC-1α expression compared with the EtOH group. BT reduced the secretion of inflammatory factors and blocked the P2X7rNLRP3 signaling pathway. Collectively, BT attenuated lipid accumulation and metaflammation by regulating the lipin1/2-mediated P2X7r signaling pathway.

Corona virus disease 2019 (COVID-19) is an infec¬tious disease endangering the respirator)' traet and multiple or¬gans of the whole body caused by severe aeute respirator)' syn¬drome coronavirus 2 ( SARS-CoV-2).More than 200 million people in the world have been infected with the disease, which is an unprecedented global plague.Most patients with C0VID-19 only show mild symptoms with a good prognosis, but about 20% of them may develop into severe cases and eause serious compli-cations, including acute respirator)' distress syndrome ( ARDS) , systemic inflammatory response syndrome (SIRS) , cytokine re¬lease syndrome (CRS) , etc.Pyroptosis is a kind of programmed cell death characterized by significant inflammatory response.It is often mediated by inflammatory caspase and the gasdermin family of membrane perforating proteins is the final effector mol¬ecules, resulting in cell membrane swelling and rupture to death, accompanied by the release of a large number of pro-in¬flammatory cytokines (such as IL-lp and IL-18, etc).Pyropto- sis affects the occurrence, progression and treatment of many diseases due to its inflammatory and morphological characteris¬tics, and also plays an important role in severe COVID-19.Therefore, drugs that target key molecules in the pyroapoptotic pathway could he a promising breakthrough for treating severe COVID-19.This article reviews the role of pyroptosis in severe COVID-19 complications ARDS and CHS.

Objective To investigate the expression of interleukin-17 (IL-17) in peripheral blood mononuclear cells (PBMC) of patients with multiple myeloma and analyse it's clinical significance.Methods Thirty patients with multiple myeloma in the Department of Hematopathy,the Third Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2017 were selected as observation group;and thirty healthy donors whose gender and age machted with patients in the observation group were selected as control group.Peripheral blood mononuclear cells were obtained from subjects in observation group and control group by using the method of density gradient centrifugation.The content of IL-17 in supernatant of PBMC culture solution of subjects in the two groups was detected by enzyme linked immunosorbent assay and the expression of IL-17 mRNA in PBMC was detected by quantitative real-time polymerase chain reaction;the cellular morphology of PBMC of subjects in control group was observed by scanning electron microscope after co-culturing with the serum of patients in observation group.Results The content of IL-17 in supernatant of PBMC culture solution of subjects in the observation group and control group was (30.79 ± 4.96),(10.10 ± 4.15) ng · L-1 respectively;the content of IL-17 in supernatant of PBMC culture solution of subjects in the observation group was significantly higher than that in the control group (t =3.412,P ＜ 0.05).The expression of IL-17 mRNA in PBMC in the observation group and control group was 4.28 ± 1.34 and 2.45 ±0.95 respectively;the expression of IL-17 mRNA in PBMC in the observation was significantly higher than that in the control group (t =2.796,P ＜0.05).After co-culturing of PBMC of subjects in the control group with the serum of patients in the observation group,the morphology of PBMC changed obviously,and membrane desquamate,membrane disintegration,even membranolysis were observed in some cells with the prolongation of co-culture time.Conclusion The over-expression of IL-17 in PBMC of patients with multiple myeloma may play a certain role in the occurrence and development of this disease.

Objective To analyze the clinical characteristics of pituitary stalk interruption syndrome(PSIS). Methods The clinical data including clinical manifestations,laboratory tests,and imaging findings of 114 PSIS patients in our hospital were retrospectively analyzed. Results Of these 114 PSIS patients,102 cases (89.4%) were male. The average age was 21.1?6.1 years. A history of breech delivery was documented in 91 cases (91.9%). Short stature was found in 89 cases (71.8%) and bone age delayed (6.1?5.1) years. Secondary sex characteristics were poor or undeveloped in most patients. The prevalence of deficiencies in growth hormone,gonadotropins,corticotropin,and thyrotropin were 100.0%,94.0%,84.2%,and 74.6%,respectively. Hyperprolactinemia was found in 28.1% of patients. Three or more pituitary hormone abnormalities were found in 105 cases(92.1%). Compared with the 5 cases with history of cephalic delivery,no difference were found in the aspects of height(t=0.297,P=0.634),penile length(t=1.205,P=0.882),testicular volume (U=99.000,P=0.348),growth hormone peak (U=89.000,P=0.186),adrenocorticotropic hormone peak(U=131.000,P=0.967),luteinizing hormone peak(U=98.500,P=0.582),thyroid-stimulating hormone (U=82.000,P=0.162),and the height of anterior pituitary (t=1.676,P=0.107) in the 53 cases with history of breech delivery. Conclusions The clinical manifestations,symptoms,hormone deficiencies were severe in our series. The condition severities were not remarkably different in patients with different delivery ways.

Muscle-derived stem cells (MDSC) are defined as myogenic stem cells endowed with their ability to self-renew and differentiate into multiple cell types of their derivative tissue, and are proved to be over 10 times more efficient in hematopoiesis than hematopoietic stem cells (HSC). Although the mechanism which MDSC differentiate into blood cells is still unclear, MDSC were considered to replace HSC to treat the patients suffering from bone marrow diseases such as aplastic anemia and tumor. MDSC are different from HSC in a variety aspects like biological characteristics, protein expression and cell proliferation. On the other hand, MDSC contain multiple distinct stem cell populations. Among these, there is only a small part with the ability to repopulate hematopoietic cells, and it is still uncertain whether their origin is same as HSC. This review summarizes the difference between MDSC and HSC, the ability of MDSC to repopulate hematopoietic cells, and the prospect of MDSCs' transplantation.

This study was purposed to analyse the clinical efficacy of autologous peripheral blood stem cell transplantation (APBSCT) in 13 Patients with AML1/ETO (+) acute myeloid leukemia, and to evaluate the role of quantitative detecting the AML1/ETO gene in treatment of AML patients. A total of 13 patients with AML1/ETO (+) acute myeloid leukemia treated with APBSCT from August 2007 to November 2012 were retrospectively analyzed. The median follow-up time was 26 (7.8-75.8)months. Kaplan-Meier analysis was used to calculate the overall survival (OS), leukemia-free survival (LFS) and cumulative relapse rate (RR). Log rank method was used to perform univariate analysis. The results showed that the 3 year-OS, LFS, and RR were (70.5 ± 15.3)%, (51.3 ± 16.7)%, 48.7%, respectively. The AML1/ETO expression level in 4 cases out of 5 relapsed patients was quantified during and after therapy, and the result showed that AML1/ETO expression level significantly increased before morphological relapse. In univariate analysis, there was no statistic significance in terms of age, sex, count of white blood cells at diagnosis, interval from diagnosis to transplantation, count of MNC for infusion. It is concluded that APBSCT has good therapeutic effect on AML1/ETO (+) AML, and regular quantitative monitoring of AML1/ETO expression level can predict early recurrence. Allogeneic hematopoietic stem cell transplantation after relapse may contribute to obtain opportunity to achieve the long-term survival for intermediate and high risk patients.
