Evaluation of RET-He values as an early indicator of iron deficiency anemia in pregnant women

Abstract Introduction During pregnancy, women are at an increased risk of developing iron-deficiency anemia. Objective The objective of this study was to assess the diagnostic performance of the reticulocyte hemoglobin equivalent (RET-He) in the early detection of iron-deficiency anemia in a group of pregnant women and to establish a reference range for this parameter in a group of control individuals. Method: A total of 60 patients and 130 control subjects were included in the study. Blood samples collected from the subjects were submitted to a complete blood count and a serum ferritin test and the data were analyzed by comparing the groups and ROC curves. Results The reference range found for the RET-He was between 29.75pg and 38.24pg, with a median of 35pg. The receiver operating characteristic (ROC) curve analysis for the ferritin parameter showed an area under the curve of 0.732 for the RET-He, 0.586 for hemoglobin, 0.551 for the mean corpuscular hemoglobin concentration and 0.482 for the mean corpuscular volume. Conclusion Early diagnosis of iron deficiency anemia in pregnancy is essential to prevent damage to both maternal and fetal health. The RET-He presents an excellent potential as an auxiliary tool for the diagnosis of iron deficiency in pregnant women.

Medication and prescription rules for treating spleen and stomach diseases in Prescriptions of Peaceful Benevolent Dispensary / 数字中医药（英文）

@#【Objective】   To explore the prescriptions related to the treatment of spleen and stomach diseases in Prescriptions of Peaceful Benevolent Dispensary (Tai Ping Hui Min He Ji Ju Fang,《太平惠民和剂局方》, TPHMHJJF), and investigate the medication and prescription rules. 【Methods】   The prescriptions of TPHMHJJF for treating spleen and stomach diseases were screened, and the data set was established by entering the prescriptions and standardized drug names using WPS Excel 2019. Herb frequency statistics, efficacy categorization, property, flavor, meridian tropism, association rules, cluster analysis, factor analysis, and complex network analysis were performed using Python 3.6.8 programming language and Gephi 0.9.2 visualization software. 【Results】   A total of 239 prescriptions were included after the screening, and the dosage forms were mainly pills and powders. The study involved 200 herbal medicines, among which 40 herbs had a frequency of ≥ 12. The herb with the highest frequency was Ganjiang (Zingiber Rhizoma). The herb properties were mainly warm in nature, with the most pungent herbs. Most herbs were attributed to the spleen and stomach meridians, and tonifying medicine were the main species. The association rule analysis identified 26 second-order association rules and 16 third-order association rules, with "Renshen (Ginseng Radix et Rhizoma) → Fuling (Poria)" as the leading rule in the former and "Fuling (Poria) + Baizhu (Atractylodis Macrocephalae Rhizome) → Renshen (Ginseng Radix et Rhizoma)" as the leading rule in the latter. Also, cluster analysis divided the top 30 herbs into six herb combinations that can warm the middle, move Qi, and dry dampness effectively. Factor analysis extracted 13 common factors, with Renshen (Ginseng Radix et Rhizoma), Fuling (Poria), and Baizhu (Atractylodis Macrocephalae Rhizome) as the highest contributing factors. Lastly, complex network analysis yielded the core prescription of 14 herbs, with Ganjiang (Zingiber Rhizoma), Renshen (Ginseng Radix et Rhizoma), Gancao (Glycyrrhizae Radix et Rhizome), and Chenpi (Citri Reticulatae Pericarpium) among the herbs with a higher weighting degree. 【Conclusion】  TPHMHJJF is mainly based on the use of warming herbs to treat spleen and stomach diseases, and its medication rule can be summarized into three aspects: (i) primarily using warming and tonifying to warm the middle and dissipate cold, (ii) using the method of moving Qi with aromatic nature to delight the spleen and appetize the stomach, and (iii) emphasizing the regulation of Qi and blood to calm the five zang-organs.

Effect of electroacupuncture on enteric neuronal autophagy in functional constipation mice / 中国针灸

OBJECTIVES@#To explore the effect mechanism of electroacupuncture (EA) on functional constipation (FC) at the combined lower he-sea and front-mu points of large intestine based on enteric neuronal autophagy.@*METHODS@#A total of 40 SPF Kunming mice were randomly divided into 5 groups (n = 8), i.e. a control group, a model group, an acupuncture group, a 3-methyl adenine (3-MA) group, and a 3-MA + acupuncture group. Except the control group, the FC model was established by gavage with compound diphenoxylate suspension for 14 days in the other 4 groups. After successful modeling, the mice of the acupuncture group and the 3-MA + acupuncture group received EA at bilateral "Tianshu" (ST 25) and "Shangjuxu" (ST 37), stimulated for 30 min with disperse-dense wave, 2 Hz/15 Hz of frequency, 1 mA of intensity. EA was delivered once daily. One course of treatment was composed of 5 days and 2 courses were needed, with an interval of 2 days. An intraperitoneal injection of 3-MA (15 mg/kg) was administered 30 min before EA in the mice of the 3-MA group and the 3-MA + acupuncture group, once daily. Before and after intervention, the time of the first black stool defecation and defecation behaviors in 6 h were observed in each group. After intervention, in every group, the small intestine propulsion rate was calculated, the colon tissue morphology was observed using HE staining, the ultrastructure of enteric neuronal autophagy was observed under transmission electron microscope, and the expressions of microtubule-associated protein 1 light chain 3 (LC3), Beclin-1 and neuronal nuclear antigen protein (NeuN) in neurons of colonic muscularis were determined by immunohistochemistry.@*RESULTS@#Before intervention, when compared with those in the control group, the time of the first black stool defecation was prolonged (P<0.01, P<0.05), and numbers (P<0.01), wet weight (P<0.01, P<0.05) and water content (P<0.05, P<0.01) of stool in 6 h were reduced in the model, acupuncture, 3-MA and 3-MA + acupuncture groups. After intervention, compared with those in the control group, the time of the first black stool defecation was longer (P<0.05), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were decreased in the model group. The time of the first black stool defecation was shortened (P<0.01), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were increased in the acupuncture group when compared with those in the model group. The time of the first black stool defecation was extended (P<0.01), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were declined in the 3-MA + acupuncture group in comparison with those in the acupuncture group. All layers of colon tissue were normal and intact in each group. When compared with the control group, the small intestine propulsion rate and the average optical density (OD) values of LC3, Beclin-1 and NeuN in neurons of colonic muscularis were decreased (P<0.01), and autophagosomes were dropped in the model group. In the acupuncture group, the small intestine propulsion rate and the average OD values of NeuN, LC3 and Beclin-1 in neurons of colonic muscularis increased (P<0.01,P<0.05), and autophagosomes were elevated when compared with those in the model group. The small intestine propulsion rate and the average OD values of NeuN, LC3 and Beclin-1 in neurons of colonic muscularis were dropped (P<0.05,P<0.01) in the 3-MA + acupuncture group in comparison with those in the acupuncture group.@*CONCLUSIONS@#Electroacupuncture may promote enteric neuronal autophagy and increase the number of neurons so that the intestinal motility can be improved and constipation symptoms can be relieved in FC mice.

Application of Rapid HE Staining in Cytological Rapid On-site Evaluation of Peripheral Lung Cancer Needle Biopsy / 中国肺癌杂志

BACKGROUND@#Rapid on-site evaluation (ROSE) is a technique used for simultaneous evaluation of biopsy specimens through rapid cytology staining. Diff-Quik (DQ) staining is the most commonly employed method for cytological rapid on-site evaluation (C-ROSE). However, the utilization of DQ staining for on-site cytological interpretation remains uncommon among pathologists in China, posing challenges to the implementation of C-ROSE. This study aims to assess the application of rapid hematoxylin-eosin (HE) staining and DQ staining for C-ROSE during percutaneous needle biopsy of peripheral lung cancer and evaluate the value of rapid HE staining in C-ROSE.@*METHODS@#Computed tomography (CT)-guided lung biopsies were conducted on 300 patients diagnosed with peripheral lung cancer. The patients were randomly assigned to two groups for C-ROSE using either rapid HE staining or DQ staining, and subsequently the two methods were compared and evaluated.@*RESULTS@#The concordance rate between C-ROSE and histopathological diagnosis was 96.7%. The median staining time for rapid HE staining was 160 s, while that for DQ staining was 120 s, representing a significant difference between the two groups (P<0.001). However, there were no significant differences observed in terms of total biopsy time, concordance rate with histopathology, cytology specimen peeling rate, and incidence of serious adverse reactions between the two groups (P>0.05).@*CONCLUSIONS@#Both staining methods comply with C-ROSE criteria in the biopsy setting of peripheral lung cancer. Rapid HE staining is more aligned with domestic clinical requirements and holds potential for further promotion and adoption in C-ROSE.

ObjectiveTo explore the practical value of environment-friendly sample release agent combined with ultrasound in the preparation of pathological tissue sections. MethodsFrom February 2013 to December 2022， 2 518 pathological specimens submitted by Foshan Municipal Hospital of Traditional Chinese Medicine were selected as the study objects. Two samples of the same specimen were randomly divided into two groups： the environment-friendly fast group， in which the pathological tissue sections were made by using the environment-friendly sample release agent combined with ultrasound； and the traditional group， in which formaldehyde， ethanol and xylene were used to make slices in the conventional way. The differences of hematoxylin （HE） staining effect， immunohistochemistry （IHC） staining effect and MDM2 gene detection result of atypical lipomatous tumor/highly differentiated liposarcoma （ALT/WDL） tissue sections between the two groups were compared. Results① The wax of the two groups' pathological tissues was dehydrated well and the tissue hardness was moderate. After HE staining， the sections of the two groups were intact， without cracks and tremor marks， and the contrast between nucleus and cytoplasm was appropriate， with good transparency， uniform staining， and no tissue loss. The excellent rate and score of HE staining in the environmental fast group were higher than those in the traditional group， but the difference was not statistically significant （χ2 = 3.125，P1 = 0.070；t = 0.965，P2 = 0.334）. ②After IHC staining of the two groups of sections， the positive location of the cells was accurate， the staining was specific and uniform， the staining intensity was moderate， the staining sensitivity was good， and there was no tissue loss. The excellent rate of IHC staining and the positive rate of IHC staining in the environmental fast group were lower than those in the traditional group， but the difference was not statistically significant （χ12 = 2.769，P1 = 0.092；χ22 = 0.800，P2 = 0.375）. ③The background and outline of the two groups of WDL tissue sections were clear， the staining was uniform， the cells were clear and visible， the nuclear boundary was clear， the hybridization signal was clear and bright under the background fluorescence， and there was no miscellaneous signal. The two groups of sections were hybridized successfully， and MDM2 showed positive amplification. The number of cells successfully hybridized in the environment-friendly fast group was lower than that in the traditional group， but the difference was not statistically significant （t = 1.414，P = 0.230）. ConclusionsThe tissue treatment method of using environment-friendly sample release agent combined with ultrasound can ensure the detection effect of HE staining， IHC staining and MDM2 gene detection of pathological tissue sections， and is more efficient and environment-friendly， suitable for promotion and use in hospitals at all levels.

Discussion on the mechanism of Yanghe Decoction in treating chronic osteomyelitis based on network pharmacology and molecular docking / 国际中医中药杂志

Objective:To study the active components and their potential mechanism of Yanghe Decoction for the treatment of chronic osteomyelitis (CO) via the methods of network pharmacology and molecular docking.Methods:Active components and action targets of Yanghe Decoction were screened from TCMSP, BATMAN-TCM and relevant literature. GeneCards, OMIM, DisGeNET, and PharmGKB databases were used to predict the targets for the CO. Cytoscape 3.8.0 software and STRING database were used to build the networks of "Chinese materia medica-active components-potential targets" and "protein-protein interaction", and according to topological parameters in the network, the core active components as well as Hub genes were screened. MCODE plug was used to accomplish clustering analysis of protein modules in PPI network. Then, intersection targets were enriched and analyzed by GO and KEGG in KOBAS database. Finally, molecular docking was carried out with the help of Autodock tool platform to predict the binding ability between the main active components and key targets.Results:A total of 120 active components of Yanghe Decoction and 402 targets were obtained; 1 464 CO-related targets were screened, and there were 103 intersection target genes of Yanghe Decoction-CO, 110 active components related to intersection targets, which mainly contained some flavonoids and Phytosterols, such as quercetin, Kaempferol, and Beta-Sitosterol. There were 9 Hub genes, including TNF, IL6, AKT1, etc., and 4 protein modules which involved the regulation of immune inflammatory response, vascular microcirculation, bone development, and formation, material synthesis and metabolism and other physiological processes. 193 signaling pathways and 1 552 GO results were acquired in KOBAS database. Molecular docking results showed that the active compounds had good binding activity with key targets based on the minimum binding energy of less than - 5 kcal/mol.Conclusion:The mechanism in the treatment of CO with Yanghe Decoction is a complex process of multiple components, multiple targets, and multiple pathways. It mainly regulates targets such as TNF, IL-6, CXCL8, VEGFA, and AKT1 through pathways such as TNF signaling pathway, IL-17 signaling pathway, and Toll-like receptors, participating in local inflammatory reactions, microcirculation, and bone cell metabolism in chronic osteomyelitis, and interfering with the immune escape mechanism of pathogenic bacteria.

Establishment of a mouse model of acute systemic cold injury induced by hypothermia / 中华急诊医学杂志

Objective:To establish an animal model of acute systemic cold injury in mice.Methods:There were 98 C57BL/6 mice, half male and half female, with body weight of 22-27 g and age of 10 weeks. The mice were randomly divided into 7 groups ( n=14) according to the changes of anal temperature in cold environment, namely, group A (38.5 ± 1) ℃, group B (35 ± 1) ℃, group C (30 ± 1) ℃, group D (25 ± 1) ℃, group E (20 ± 1) ℃, group F (15 ± 1) ℃, and group G (10 ± 1) ℃, among which, group A was the blank control group, and the rest groups were the experimental group. The mice in the blank control group were placed in the normal environment (20 ± 5) ℃, and the mice in the experimental group were placed in the low temperature artificial climate box at - 20℃. The anal temperature of the mice was measured intermittently (as the core temperature), and the time required for the core temperature of the mice to drop to groups B, C, D, E, F and G was recorded. The righting reflex was used to evaluate the consciousness state, the action ability and the general state of each organ of mice were observed, and the blood routine and HE staining of each organ were detected. Results:The lower the core temperature of the experimental group, the longer the time required. The consciousness state, action ability, general state of organs, blood routine, and HE staining of organs in groups B, C, and D were basically the same as those in group A, and there was no acute systemic cold injury. Therefore, the blood routine, general observation of organs, and HE staining of organs in groups B, C, and D were no longer displayed compared with those in group A. Compared with group A, mice in group E began to suffer from disturbance of consciousness and action ability. With the decrease of core body temperature, the damage was aggravated, and mice in group G died. Compared with group A, the indices of blood routine test (WBC, RBC, HGB, PLT) of mice in group E began to decrease, and the univariate variance calculation showed that only WBC changes had statistical significance ( P<0.05). Compared with groups A and E, the indices of blood routine test (WBC, RBC, HGB, PLT) of mice in group F were further reduced, and the changes of each index in univariate variance calculation were statistically significant ( P<0.05). The general observation results showed that compared with group A, the lung, liver and spleen surfaces of mice in group E began to darken, and compared with groups A and E, the lung, liver, spleen, kidney and heart of mice in group F were further deepened and darkened, with irregular edges. HE staining results of various organs showed that compared with group A, the mice in group E began to have partial alveolar structure destruction and a small amount of inflammatory cell infiltration, the central vein of the liver was slightly congested, and the red and white pulp of the spleen were indistinct. Compared with groups A and E, the pathological structure damage of the lung, liver, spleen, kidney, heart and brain tissues of the mice in group F was further aggravated. Conclusions:Detection of consciousness state, action ability, general state of organs, blood routine and HE staining indices of organs in mice under low temperature can simulate the progress of clinical acute cold injury, and the animal model of acute systemic cold injury was successfully prepared.

An experimental study of tangzhouling on morphological changes of nissl bodies in the dorsal root ganglion of DM rats / Un estudio experimental de tangzhouling sobre los cambios morfológicos de los cuerpos de nissl en el ganglio de la raíz dorsal de ratas DM

SUMMARY: This study aims to investigate the effect of Tangzhouling on the morphological changes of Nissl bodies in the dorsal root ganglion of DM Rats. In this study, 69 rats were randomly divided into a control group (n = 10) and a model group (n = 59). The rats in the model group were randomly divided into a diabetic group (n = 11), a vitamin C group (n = 12), a low dose Tangzhouling group (n = 12), a medium dose Tangzhouling group (n = 12) and a high dose Tangzhouling group (n = 12). The dose of Tangzhouling in the low dose group was 5 times that of the adult dose, being 0.44g/kg/d. The dose of Tangzhouling in the medium dose group was 10 times that of the adult dose, being 0.88g/kg/d. The dose of Tangzhouling in the high dose group was 20 times that of the adult dose, being 1.75g/kg/d. All doses above are crude drug dosages. Rats in the vitamin C group were given 10 times the dose of an adult, being, 0.05 g/ kg/d. The diabetic group and the control group were given the same amount of distilled water. Drug delivery time is 16 weeks. The dorsal root ganglion was placed in a freezing tube at the end of the experiment. The morphological changes of Nissl bodies in the dorsal root ganglion were detected by HE and Nissl staining. The study results showed that vitamin C had no significant effect on the quantity, size and nucleolus. Tangzhouling can improvee the morphology, quantity and nucleolus of Nissl bodies to a certain extent, and the high dose is better than the lower dose. Tangzhouling capsules can improve the nerve function of DM rats through Nissl bodies.

RESUMEN: Este estudio tuvo como objetivo investigar el efecto de Tangzhouling en los cambios morfológicos de los cuerpos de Nissl en el ganglio de la raíz dorsal de las ratas DM. En este estudio, 69 ratas se dividieron aleatoriamente en un grupo control (n = 10) y un grupo modelo (n = 59). Las ratas del grupo modelo se dividieron aleatoriamente en un grupo diabéticos (n = 11), un grupo vitamina C (n = 12), un grupo de dosis baja de Tangzhouling (n = 12), un grupo de dosis media de Tangzhouling (n = 12) y un grupo de dosis alta de Tangzhouling (n = 12). La dosis de Tangzhouling en el grupo de dosis baja fue 5 veces mayor que la dosis del adulto, siendo 0,44 g/kg/d. La dosis de Tangzhouling en el grupo de dosis media fue 10 veces mayor que la dosis del adulto, siendo 0,88 g/kg/d. La dosis de Tangzhouling en el grupo de dosis alta fue 20 veces mayor que la dosis del adulto, siendo 1,75 g/kg/d. Todas las dosis anteriores son dosis de fármaco crudo. Se les administró 10 veces la dosis de un adulto a las ratas del grupo vitamina C, siendo 0,05 g/kg/d. El grupo de diabéticos y el grupo de control recibieron la misma cantidad de agua destilada. El tiempo de entrega del fármaco fue de 16 semanas. El ganglio de la raíz dorsal se colocó en un tubo de congelación al final del experimento. Los cambios morfológicos de los cuerpos de Nissl en el ganglio de la raíz dorsal se detectaron mediante tinción de HE y Nissl. Los resultados del estudio mostraron que la vitamina C no tuvo un efecto significativo sobre la cantidad, el tamaño y el nucléolo. Tangzhouling puede mejorar la morfología, la cantidad y el nucléolo de los cuerpos de Nissl hasta cierto punto, y es mejor la dosis alta que la dosis baja. Las cápsulas de Tangzhouling pueden mejorar la función nerviosa de las ratas DM a través de los cuerpos de Nissl.

Cell HE staining smears and paired cell paraffin sections in detection of epithelial growth factor receptor gene of pleural fluid specimens / 中南大学学报(医学版)

OBJECTIVES@#The advanced non-small cell lung cancer (NSCLC) patients with pleural effusion have no opportunity for surgery treatment. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are the first-line drugs for these patients with EGFR-sensitive mutation. However, the disease progression and drug update during or after treatment of EGFR-TKIs bring more challenges and puzzles to clinical diagnosis and treatment, which inevitably requires archived pleural cell samples for EGFR re-examination or comparative study. Understanding the DNA quality of archived pleural fluid samples and effectively using archival data of pleural fluid cells are of great significance for tracing the origin of cases and basic medical research. This study aims to evaluate the consistency of EGFR mutant gene expression between the 2 methods, and to explore a reliable way for preserving cytological data and making full use of cytological archival data via cell HE staining smear and cell paraffin section.@*METHODS@#A total of 57 pleural fluid cytology cases in the Department of Pathology of China Aerospace Center Hospital from October 2014 to April 2021 were selected. Tumor cells were detected by cell HE staining smears and immunohistochemical staining for TTF-1 and Napsin A in the paired cell paraffin sections. There were more than 200 tumor cells in cell HE staining smear and the proportion of tumor cells were ≥70% in matched cell paraffin sections. Patients with 2 cell smears (one for cell data retention and the other for DNA extraction) were selected as the research subjects, and 57 pleural fluid samples were enrolled. EGFR gene mutation was detected by amplification refractory mutation system-polymerase chain reaction in 57 paired cell HE staining smears and cell paraffin sections. DNA concentration was 2 ng/μL. Cell HE smear was amplified side-by-side with DNA samples from paired cell paraffin sections. Result determination was according to the requirements of the reagent instructions. The external control cycle threshold (Ct) value of the No. 8 well of the samples to be tested was between 13 and 21, which was considered as successful and reliable samples. When the Ct value of EGFR gene mutation was <26, it was considered as positive; when the Ct value was between 26 and 29, it was critical positive; when the Ct value was equal or more than 29, it was negative. ΔCt value was the difference between mutant Ct value and externally controlled Ct value. The smaller the ΔCt value was, the better the quality of DNA of the detected sample was.@*RESULTS@#Among the 57 pleural effusion samples, 42 patients were hospitalized with pleural effusion as the first symptom, accounting for 73.7% (42/57). EGFR mutation was detected in 37 samples [64.9% (37/57)]. The mutation rate for 19del was 37.8% (14/37) while for L858R was 48.6% (18/37). Females were 56.7% (21/37) of mutation cases. The mutation consistency rate of cell HE staining smear and matched cell paraffin sections was 100%. The ΔCt values of cell HE staining smears were less than those of matched cell paraffin sections. The mutation Ct values of 37 cytological samples were statistically analyzed according to the preservation periods of the years of 2014-2015, 2016-2017, 2018-2019, and 2020-2021. There were significant differences in cell paraffin section in the years of 2014-2015 and 2016-2017 compared with the years of 2018-2019 and 2020-2021, while no significant differences were found in cell HE staining smear. Statistical analysis of externally controlled Ct values of 57 cytological samples showed that there were significant differences between cell HE staining smears and cell paraffin section in the years of 2014-2015 and 2016-2017, compared with the years of 2018-2019 and 2020-2021. The mutational Ct values of 37 paired cell blocks and smears were all <26, and the externally controlled Ct values of 57 paired cell paraffin sections and HE staining smears were all between 13 and 21.@*CONCLUSIONS@#The DNA quality of cell HE smears and matched cell paraffin section met the qualified requirements. Two methods possess show an excellent consistency in detecting EGFR mutation in NSCLC pleural fluid samples. The DNA quality of cell HE staining smear is better than that of cell paraffin sections, so cell HE staining smear can be used as important supplement of the gene test source. It should be noted that the limitation of cell HE staining smears is non-reproducibility, so multiple smears of pleural fluid are recommended to be prepared for multiple tests.

Evaluation of the treatment of functional dyspepsia of deficiency cold of spleen and stomach by He Style fire acupuncture / 国际中医中药杂志

Objective:To observe the curative effect of He Style fire acupuncture on functional dyspepsia of deficiency cold of spleen and stomach syndrome.Methods:Sixty patients who met the inclusion criteria from March 2017 to March 2019 in Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University were divided into 2 groups according to the random number table method, with 30 in each group. The control group was given mosapride tablets, one tablet (5 mg) each time half an hour before meals. On the basis of the control group, the treatment group was given fire acupuncture on Zusanli(ST36), Zhongwan(CV12), Pishu(BL20), Weishu(BL21), Guanyuan(CV4) and Qihai (CV6) twice a week. The course of treatment for both groups of patients was 4 weeks. A follow-up was visited at 1 month after the treatment. The total Symptom Scores and Health-Related Quality of Life Scale (SF-36) scores were performed before and after treatment, and the total scores of syndromes of patients with Deficiency cold of spleen and stomach before and after treatment were used for clinical efficacy evaluation, and adverse events during treatment were recorded.Results:The total efficiency of the treatment group was 93.3% (28/30), and 76.7% (23/30) in the control group, and the 2 groups were statistically significant ( χ2=4.78, P<0.05). After treatment, the upper abdominal pain, upper abdominal burning, postprandial fullness and discomfort, early satiety, and total scores in the treatment group were significantly lower than those in the control group ( t values were 4.27, 5.16, 3.93, 4.69, 4.28, respectively, all Ps<0.05); during follow-up, the upper abdominal pain, upper abdominal burning, postprandial fullness and discomfort and the total scores in the treatment group were significantly lower than those in the control group ( t values were 3.63, 3.22, 4.03, 3.04, respectively, all Ps<0.05). In terms of SF-36, after treatment, the treatment group showed significantly higher scores in the control group of physical function, physiology, mental health, and health changes compared with the control group ( t values were 2.97, 4.05, 4.22, 3.05, respectively, all Ps<0.05). During follow-up, the treatment group with physiological function, physical function, physical pain, overall health, life vitality, mental health, health changes scores were significantly higher than those in the control group ( t values were 3.27, 4.23 3.85, 3.15, 3.25, 6.15, 3.85, respectively, all Ps<0.05). Conclusion:He Style fire acupuncture combined with western medicine treatment can improve the symptoms of upper abdominal pain and upper abdominal burning, and the quality of lifein the patients with functional dyspepsia.

Exploring the Legend of Kososan / 日本東洋医学雑誌

In the clause of kososan (Xiāng sū sàn), which was added in “Wazaikyokuho (Hé jì jú fāng)” during the shàoxīng period (1131-1162), there is an anecdote that only the clan used this prescription showed defense against the epidemics at that time. Jiangnan area is the near place where COVID-19 became a pandemic in 2020. Considering these backgrounds and the similarities between the patterns (TM1) from the view point of Kampo medicine and prescriptions including kososan listed in the chapter of Cold Damage (Shanghan) of “Wazaikyokuho,” I hypothesized that formulas from this chapter may be effective for COVID-19. Many prescriptions including kososan in the chapter of Cold Damage were developed for the treatment of epidemics in the Jiangnan area during the Southern Song Dynasty. Epidemics were common at that time and place, and the prescriptions were left for posterity. The Kampo patterns (TM1) of COVID-19 were considered to have characteristics similar to those of the epidemics of the 11-13th century. The formulas including kososan from the chapter of Cold Damage in “Wazaikyokuho” may be effective against COVID-19, which warrants further investigation.

Meta-analysis of Relationship Between Expression Level of Human Epididymis Protein 4 and Lymph Node Metastasis in Endometrial Cancer / 肿瘤防治研究

Objective To evaluate systematically the correlation between the expression level of human epididymis protein 4 (HE4) and lymph node metastasis of endometrial cancer (EC). Methods Computers were used to search for the literatures about the correlation between the expression level of HE4 and lymph node metastasis of EC in PubMed, Cochrane, Web of Science, CBM, CNKI, and Wanfang Database. The search time was from the database establishment to May 2021. Articles were screened in accordance with the inclusion and exclusion criteria, and the quality of literature was evaluated by Newcastle Ottawa scale. Stata12.0 was used to perform meta-analysis, and TSA was used to evaluate the sample size. Results A total of 2736 patients with EC were included in the 25 eligible studies. The results of meta-analysis showed that the expression level of HE4 in the EC-lymph-node metastasis group was significantly higher than that in the non-metastasis group (SMD=1.58, 95%CI: 1.13-2.03), and meta-regression analysis revealed that the results were related to the average age of patients in each study. TSA analysis exhibited that the total sample size of the included studies met the requirements. Conclusion The expression level of HE4 is correlated with lymph node metastasis of EC, and this correlation may be affected by age, body mass index, and other factors. The correlation weakens with the increase in age.

He-Wei Granule enhances anti-tumor activity of cyclophosphamide by changing tumor microenvironment / 中草药·英文版

Objective: He-Wei Granule (HWKL) is a modern product derived from the modified formulation of traditional Chinese medicine Banxia Xiexin Decoction (BXD), which remarkedly enhanced the anti-proliferation activity of cyclophosphamide (CTX) on HepG2 and SGC-7901 cell lines in vitro in our previous research. The aim of the study was to investigate the synergistic effects of HWKL and CTX using a transplanted H22 hepatocellular carcinoma mouse model. Methods: The CTX-toxic-reducing efficacy of HWKL was evaluated by hematology indexes, organ indexes and marrow DNA detection. To investigate the underlying mechanisms, histopathology test, immunohistochemistry test and TUNEL staining were conducted. The efficacy of HWKL on the micro-vessel density (MVD) in tumor tissue was also evaluated by measuring CD34 level. Results: High dose HWKL (6.75 g/kg) markedly attenuated CTX-induced hepatotoxicity and myelosuppression while significantly enhanced CTX anticancer efficacy in vivo. Further mechanism investigation suggested that high dose HWKL significantly increased cleaved Caspase 3 level and promoted apoptosis in tumor tissue by up-regulating Bax expression and down-regulating Bcl-2 and FasL expressions. Compared with CTX alone group, the decrease in LC-3B and Beclin 1 levels suggested that the autophagy in H22 carcinoma was significantly inhibited with addition of high dose HWKL. ELISA assay results indicated that the autophagy inhibition was achieved by decreasing p53 expression, blocking PI3K/AKT/mTOR pathway and recovering Th1/Th2 cytokine balance. In addition, CD34 and EGFR immunohistochemistry assay suggest that high dose HWKL could significantly decrease micro-vessel density (MVD) and inhibit angiogenesis in H22 carcinoma. Conclusion: It can be concluded that high-dose HWKL enhanced CTX efficacy by promoting apoptosis, inhibiting autophagy and angiogenesis in tumor tissue while significantly alleviated CTX-induced toxicity, and could be applied along with CTX in clinical treatment as a supplement agent.

Assessing the diagnostic performance of four ovarian malignancy prediction risk models in differentiating benign and malignant ovarian masses in a tertiary hospital / Philippine Journal of Obstetrics and Gynecology

Introduction@#Ovarian cancer is considered the most lethal gynecologic malignancy because it is difficult to diagnose in its early stages. Ovarian malignancy prediction models may be useful in discriminating between benign and malignant masses, allowing for accurate and timely referral as well as proper therapeutic care@*Objective@#To evaluate the diagnostic performance of the four ovarian prediction models: Risk of Malignancy Index‑4 (RMI‑4), Risk of Ovarian Malignancy Algorithm (ROMA), Copenhagen Index (CPH‑I), and International Ovarian Tumor Analysis (IOTA)‑Assessment of Different NEoplasias in the AdneXa (ADNEX) in identifying malignant and benign ovarian masses@*Materials and Methods@#This was a retrospective, cross‑sectional, analytical diagnostic study in a tertiary hospital between January 2017 and December 2020. Receiver operating characteristic (ROC) curves, area under the curves (AUCs), sensitivities, specificities, positive and negative predictive values, and positive and negative likelihood ratios were used to assess the diagnostic performance of the prediction models.@*Results@#We analyzed a total of 248 patients. One hundred and sixty‑one (65%) had benign tumors, 28 (11%) had borderline, and 59 (24%) had malignant tumors. The AUCs of all models were all above 90%, but when compared to the other models, CPH‑I had the best estimate. RMI‑4 had the highest sensitivity (98.3%) in diagnosing malignancy. For appropriately diagnosing benign disease, the IOTA‑ADNEX model exhibited the highest specificity (92.1%). Overall, RMI‑4 had the lowest diagnostic accuracy (74.6%), whereas IOTA‑ADNEX had the greatest (93.2%).@*Conclusion@#The four malignancy prediction models in this study were all useful tools in discriminating between benign and malignant ovarian tumors. IOTA‑ADNEX, CPH‑I, and ROMA all demonstrated overlapping diagnostic performances indicating that they are equal in that regard. In terms of sensitivity in predicting malignancy, RMI‑4 was the most sensitive. CPH‑I is the predictor with the best overall estimate. Lastly, IOTA‑ADNEX was the most specific, and displayed highest diagnostic accuracy among the four
