ABSTRACT

Objective: To analyze the case characteristics of Chronic obstructive pulmonary disease caused by occupational irritant chemicals (OI-COPD). To provide basis for revising its diagnostic criteria. Methods: From June to December 2021, we investigated the information of OI-COPD patients confirmed by Shandong Institute of Occupational Health and Prevention of Occupational Diseases, Guangxi Zhuang Autonomous Region Institute of Occupational Disease Prevention and Control, Qingdao Central Hospital affiliated to Qingdao University and other diagnostic institutions in the past five years, a total of 41 cases. The basic information of OI-COPD cases, occupational risk factors exposure information, medical history, smoking history and clinical symptoms were analyzed retrospectively. The measurement data were tested for normal distribution, which was described by x±s, and compared between groups by t test; Those who do not conform to the normal distribution are described by the median [M (Q(1), Q(3)) ] and analyzed by nonparametric test; The counting data were expressed in frequency and rate (% ), and the comparison between groups was tested. Results: Of the 41 cases, 33 were male and 8 were female. The age of the patient diagnosed with OI-COPD was (49.5±10.3) years old, and the minimum age was 30 years old; Among them, 8 patients had a definite long-term smoking history (more than 5 years) ; The exposure duration of occupational risk factors was (18.6±10.3) years, of which 3 patients had exposure duration of less than 5 years; The occupational risk factors leading to OI-COPD include acids and acid-forming compounds, bases, aldehydes, nitrogen oxides, chlorine and its compounds, etc. The exposure level of occupational risk factors is related to the degree of COPD airflow restriction (χ(2)=6.17, P <0.05). 18 patients with diagnosis age <50 years old were diagnosed as early-onset COPD. The incidence of respiratory symptoms in the early diagnosis COPD group was lower than that in the non-early diagnosis COPD group, and the FEV1% pred was significantly higher than that in the non-early diagnosis COPD group. The difference was statistically significant (P<0.01 ) . Conclusion: The exposure level of occupational risk factors may be the risk factor affecting the degree of COPD airflow restriction. With the increase of the exposure level of COPD patients, the proportion of respiratory symptoms will also increase accordingly.

ABSTRACT

ObjectiveTo reveal the mechanism of action of Huangqi Guizhi Wuwutang in the treatment of rheumatoid arthritis by pharmacological research based on its clinical application. MethodThe collagen-induced arthritis (CIA) rat model was established by injecting bovine type Ⅱ collagen and Freund's adjuvant at the tail, and was treated with different concentrations of Huangqi Guizhi Wuwutang. The rats were randomly divided into blank group, model group, methotrexate (0.9 mg·kg-1) group, and Huangqi Guizhi Wuwutang low- and high-dose (5.13, 20.52 g·kg-1·d-1) groups, with continuous intragastric administration for 4 weeks. The degree of joint swelling, weight, degree of foot swelling and arthritis index score were determined and the pathological changes of ankle joints were detected by hematoxylin and eosin (HE) staining to observe the therapeutic effect of Huangqi Guizhi Wuwutang on rheumatoid arthritis. In addition, enzyme-linked immunosorbent assay (ELISA) and Western blot were used to measure the expression of interleukin 1β (IL-1β), interleukin 6 (IL-6), interleukin 10 (IL-10) and tumor necrosis factor-α (TNF-α) in serum and the expression of nuclear factor kappa-B (NF-κB) pathway related proteins in synovial tissue, respectively to clarify the molecular mechanism of Huangqi Guizhi Wuwutang in the treatment of rheumatoid arthritis. ResultCompared with the conditions in blank group, the body weight and IL-10 level were decreased (P<0.01), and the degree of foot swelling and arthritis index score, the levels of IL-1β, IL-6 and TNF-α, and the expression of NF-κB pathway related proteins were increased (P<0.01,) in the model group, with impaired morphology and function of the ankle joint. Additionally, compared with the model group, Huangqi Guizhi Wuwutang low- and high-dose groups had increased body weight of rats and IL-10 level (P<0.01), and reduced degree of foot swelling and arthritis index score (P<0.05, P<0.01), levels of IL-1β, IL-6 and TNF-α (P<0.01) and expression of NF-κB pathway related proteins (P<0.05, P<0.01), with improved function and morphology of the ankle joint. ConclusionHuangqi Guizhi Wuwutang can significantly alleviate joint inflammatory injury by down-regulating NF-κB pathway and reducing the inflammatory response in CIA rats.

ABSTRACT

ObjectiveTo study the inhibitory effect of Banxia Houputang (BHT) on lipopolysaccharide (LPS)-induced inflammation of microglia (BV2) cells and the neuroprotective effect on human neuroblastoma (SH-SY5Y) cells. MethodAfter the neuroinflammatory model was constructed by LPS inducing BV2 cells, model group (LPS 100 µg·L-1), administration groups (LPS+1 g·L-1 BHT, LPS+2 g·L-1 BHT, LPS+5 g·L-1 BHT, LPS+10 g·L-1 BHT), and blank group were given DEME medium at the same volume. In addition, neuronal apoptosis model was established by co-culture of LPS-induced BV2 cell inflammation medium and SH-SY5Y cells (LPS-DMEM) and was administrated according to the above grouping. Cell viability was detected by Cell Counting Kit-8 (CCK-8) assay. The content of nitric oxide (NO) and that of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) were determined by Griess aasay and enzyme-linked immunosorbent assay (ELISA), respectively. The mRNA levels of TNF-α, IL-1β, interleukin-4 (IL-4), nitric oxide synthase (iNOS), and interleukin-10 (IL-10) were measured by real-time polymerase chain reaction (Real-rime PCR). Western blot was used to detect the expression levels of signal transducer and activator of transcription 3 (STAT3), Janus kinase 2 (JAK2) and nuclear factor kappa-B (NF-κB p65), protein kinase B (Akt), inhibitor of nuclear factor κB α (IκBα), B-cell lymphoma-2 (Bcl-2), and Bcl-2 associated X protein (Bax). ResultCompared with blank group, LPS increased the NO release, levels of TNF-α, IL-1β, IL-6, and iNOS and protein expression of Akt, NF-κB p65, IκBα, JAK2 and STAT3, decreased the content of IL-4 and IL-10 in BV2 cells, and induced apoptosis of co-cultured SH-SY5Y cells (P<0.01). Compared with model group, BHT reduced the content of NO, TNF-α, IL-1β, and iNOS (P<0.01) and protein expression of Akt, NF-κB p65, IκBα, JAK2 and STAT3 (P<0.01), elevated the content of IL-4 and IL-10 (P<0.01), and inhibited the apoptosis of SH-SY5Y cells induced by LPS-DMEM (P<0.01). ConclusionThis experiment reveals that BHT inhibited LPS-induced inflammation in BV2 cells by regulating Akt/NF-κB/JAK2/STAT3 signaling pathway and showed neuroprotective effects on SH-SY5Y cells.

ABSTRACT

Objective: To explore the role of nonalcoholic fatty liver disease (NAFLD) in the development of hepatocellular carcinoma (HCC) in patients with prior hepatitis B virus infection (HBsAg-negative and anti-HBC-positive). Methods: 1605 hospitalized patients who were first diagnosed with HCC at Nanfang Hospital between 2015 to 2017 were retrospectively studied. Patients who developed HCC on the basis of active HBV infection (HBsAg-positive, anti-HBc positive) were used as control. Multivariate logistic regression model was used to analyze the relationship between NAFLD and HCC in patients with prior hepatitis B virus infection. Results: Among HCC patients with both HBsAg and anti-HCV negative, the proportion of prior HBV infection accounted for 86.7%. NAFLD prevalence was higher in patients with HCC based on prior HBV infection than active HBV infection (19.7% vs. 8.5%, P < 0.001). After adjusting for gender, age, hypertension, alanine aminotransferase, and liver cirrhosis, patients with HCC based on prior HBV infection were more likely to develop NAFLD (OR: 2.29, 95% CI: 1.40-3.74), and this phenomenon was observed only in patients with non-cirrhosis (OR: 5.26, 95% CI: 2.53-10.96) and aged≥50 years (OR: 2.36, 95% CI: 1.33-4.20). Conclusion: NAFLD may be a risk factor for HCC in a previously infected patients with HBV, especially in non-cirrhotic and population aged≥50 years.

ABSTRACT

Objective: To understand the diagnosis of suspected occupational diseases reported in Guangzhou from 2014 to 2019, so as to provide theoretical basis and technical support for the supervision of suspected occupational disease reports. Methods: By cluster sampling, the suspected occupational disease report card, occupational disease report card and pneumoconiosis report card reported by Guangzhou from January 1, 2014 to December 31, 2019 in the occupational disease and occupational health information monitoring system were collected for matching analysis to understand the diagnosis of suspected occupational disease patients. Results: From 2014 to 2019, a total of 1426 suspected occupational cases in 7 categories and 32 species were reported in Guangzhou. The average number of reported cases per year was about 240. The main diseases of suspected occupational diseases were suspected occupational noise deafness (68.44%, 976/1426) , suspected occupational chronic benzene poisoning (16.48%, 235/1426) , suspected occupational other pneumoconiosis (4.84%, 69/1426) , suspected occupational silicosis (3.23%, 46/1426) and suspected occupational welder pneumoconiosis (1.82%, 26/1426) . The diagnostic rate required to enter the occupational disease diagnostic program is 36.61% (522/1426) , and the diagnostic rate is 59.20% (309/522) . In 2019, the diagnosis rate of suspected occupational diseases was the lowest (23.92%, 61/255) , Huadu District was the lowest (8.33%, 9/108) , suspected occupational pneumoconiosis was the lowest (28.03%, 44/157) , the diagnosis rate of suspected occupational diseases reported by the Centers for Disease control and prevention was the lowest (17.43%, 19/109) , and the diagnosis rate of suspected occupational diseases reported by outpatient treatment was the lowest (22.22%, 2/9) . The suspected occupational diseases reported by institutions outside Guangzhou did not enter the occupational disease diagnosis procedure. Suspected occupational skin diseases, suspected occupational diseases caused by physical factors and suspected occupational tumors were diagnosed, and the diagnosis rate of occupational disease prevention and control institutions was the highest (94.87%, 37/39) . Conclusion: The main types of suspected occupational diseases reported during these six years are noise deafness, chronic benzene poisoning and pneumoconiosis. The overall diagnosis rate and diagnosis rate of suspected occupational diseases are not high. It is suggested to improve the network direct reporting system of suspected occupational diseases and strengthen the follow-up management and supervision of suspected occupational diseases.

ABSTRACT

In this paper, the extraction rate of crude polysaccharides and the yield of polysaccharides from Hippocampus served as test indicators. The comprehensive evaluation indicators were assigned by the R language combined with the entropy weight method. The Box-Behnken design-response surface methodology(BBD-RSM) and the deep neural network(DNN) were employed to screen the optimal parameters for the polysaccharide extraction from Hippocampus. These two modeling methods were compared and verified experimentally for the process optimization. This study provides a reference for the industrialization of effective component extraction from Chinese medicinals and achieves the effective combination of modern technology and traditional Chinese medicine.

ABSTRACT

This paper aimed to explore the mechanism of the split components of Phytolaccae Radix by means of network pharmaco-logy. Based on the theoretical hypothesis of the nature and taste of traditional Chinese medicine, the chemical components of the separated components of Phytolaccae Radix were selected by using Traditional Chinese Medicine Systems Pharmacology Database(TCMSP) and Traditional Chinese Medicines IntegratedDatabase(TCMID) databases in combination with related literatures. Relevant target analysis was carried out based on PubChem and SwissTargetPrediction databases. Targets corresponding to disease were excavated based on GeneCards for each split component, corresponding potential targets were obtained through mapping the target set of target compounds to disease targets. GO biological process analysis and KEGG pathway enrichment analysis were performed on the mapped targets with the help of DAVID database. Based on Cytoscape software and the corresponding efficacy, the network diagram of "medicinal material-split components-compound-target-pathway" was constructed to explore the mechanism of different efficacy of the separated components of Cytoscape. And the target purgation and diuretic mapping was used as the target of the traditional efficacy of smoothening secretion for the first time. The study explored esculentoside component, fatty oil component and phenolic acid component, a total of 30 target compounds and 301 corresponding targets, involving 44 potential targets for "anti-inflammatory", 50 potential targets for "immunoregulation", 52 potential targets for "smoothening secretion", 28 potential targets for "antibacterial activity", 28 potential targets for "antiviral effect", and 29 potential targets for "antitumor effect". Topological analysis revealed 14 key gene targets such as MAPK8, MAPK14, EGFR and PTGS2. A total of 684 GO entries and 235 KEGG pathways were obtained through bioinformatics enrichment analysis, mainly involving TNF signaling pathway, NF-kappaB signaling pathway and MAPK signaling pathway. This study revealed the multi-component, multi-target, and multi-channel action mechanism of the split components of Phytolaccae Radix, which provided certain basis for the next step to clarify the split components of Phytolaccae Radix through the method of system biology, and injected new content and significance into the study of properties and flavors theory.

ABSTRACT

OBJECTIVE@#To evaluate the value of autism screening checklists in the early identification of autism spectrum disorder (ASD).@*METHODS@#A total of 2 571 children who attended the Children's Hospital of Chongqing Medical University and completed autism screening and diagnostic test were enrolled as subjects, among whom 2 074 were diagnosed with ASD, 261 were diagnosed with global developmental delay (GDD), 206 were diagnosed with developmental language disorder (DLD), and 30 had normal development. The sensitivity, specificity, and optimal threshold value of the Modified Checklist for Autism in Toddlers (M-CHAT) and the Autism Behavior Checklist (ABC) for the early identification of ASD were evaluated by the receiver operating characteristic (ROC) curve.@*RESULTS@#The M-CHAT had a high sensitivity of 88.3% but a low specificity of 36.0% for the identification of ASD. Its sensitivity decreased with age, and was maintained above 80% for children aged 16 to < 48 months. The ABC had a high specificity of 87.3% but a low sensitivity of 27.2%, with an optimal cut-off value of 47.5 based on the ROC curve analysis. The multivariate linear regression model based on a combination of the M-CHAT and ABC for screening of ASD showed a specificity of 85.8% and a sensitivity of 56.6%.@*CONCLUSIONS@#The M-CHAT has a high sensitivity and a low specificity in the identification of ASD, with a better effect in children aged 16 to < 48 months. The ABC has a high specificity and a low sensitivity. The multiple linear regression model method based on the combined M-CHAT and ABC to screen ASD appears to be effective.

ABSTRACT

Daturae Flos is a traditional antitussive and antiasthmatic medicine, its flowers and leaves are rich in a variety of compounds, including withanolides, alkaloids, terpenes, flavonoids and amides. Because of its antiasthmatic, antitussive, antispasmodic and analgesia effect, it is traditionally used for the treatment of asthma, cough, cold pain in abdominal cavity, rheumatic arthralgia, infantile chronic eclampsia, and can also be used as raw material for surgical anesthesia. Modern pharmacological studies have shown that in addition to the traditional efficacy, Daturae Flos also has anti-inflammatory, immunosuppression, anti-convulsion and other effects, and is often used in the treatment of psoriasis, Parkinson's disease, epilepsy, rheumatoid arthritis and other diseases. At present, the chemical constituents of Daturae Flos are mainly focused on withanolides and alkaloids. At the same time, there is a lack of clear classification of chemical components and the distribution of chemical components in medicinal parts of this medicine, and little information is available for the pharmacological effects of polysaccharides. Based on this, this paper systematically searched relevant literature of Daturae Flos, and summarized and analyzed its chemical composition, pharmacological effect and clinical application, in order to provide reference for further development and utilization of Daturae Flos.

ABSTRACT

Objective: By sorting and analyzing pertinent modern studies targeting auricular point therapy treating primary insomnia (PI), to summarize the point selection rules and clinical efficacy of using auricular points alone or combining it with other therapies in treating PI. Methods: A search on China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed, Springer and Ovid were conducted from January 1, 1998 till January 31, 2020. Point selection, diagnostic criteria and Pittsburgh sleep quality index (PSQI) in the eligible studies were analyzed and summarized. Results: The difference in PSQI before and after using auricular point therapy alone was more significant than that of using Chinese medication alone (P<0.05), but less significant than that of combining auricular point therapy and acupuncture-moxibustion and Chinese therapeutic massage (tuina) (P<0.05). In the included studies, Shenmen (TF4) was the most commonly used (370 times), followed by Heart (CO15), which was 344 times, and Subcortex (AT4), which was 325 times. In terms of auricular points distribution, points in the auricular concha were the most commonly used (1500 times), followed by those in the antitragus (474 times) and triangular fossa (387 times). Correlation analysis showed that Shenmen (TF4) and Liver (CO12), Sympathetic (AH6a) and Heart (CO15) were used together more often, followed by Shenmen (TF4), Liver (CO12), Spleen (CO13), Kidney (CO10) and Subcortex (AT4), and then Shenmen (TF4), Liver (CO12), Sympathetic (AH6a), Subcortex (AT4) and Heart (CO15). Cluster analysis showed that the auricular points used for PI can be divided into 6 clusters in 2 major groups. One group was Heart (CO15), Subcortex (AT4), Shenmen (TF4), Sympathetic (AH6a), Spleen (CO13), Kidney (CO10), Liver (CO12) and Endocrine (CO18); the other was Occiput (AT3), Stomach (CO4), Pancrease-gallbladder (CO11), Chuiqian (LO4), Small Intestine (CO6), Central Rim (AT2,3,4i) and Sanjiao (CO17). In terms of patterns in traditional Chinese medicine, the pattern of dual deficiency of heart and spleen accounted for the largest proportion in the studies of using auricular points alone or combining it with other treatments to treatment PI, and then it was the pattern of liver depression transforming into fire. Conclusion: In treatment of PI with auricular points alone or combo therapy involving auricular points, Shenmen (TF4) was commonly used, and the commonly used point group consisted of Shenmen (TF4), Liver (CO12), Sympathetic (AH6a) and Heart (CO15). Auricular point therapy can be taken as a complementary therapy in treating PI.

ABSTRACT

OBJECTIVE: To explore the correlative characteristics of the National Occupational Health Standards by social network analytic method. METHODS: The national occupational health standards were searched and collected through the National Health Commission of the People′s Republic of China and the National Institute of Occupational Health and Poison Control, Chinese Center for Disease Control and Prevention. And the normative reference file related information was extracted to build standard coupling matrix. UCINET6 software for Windows was used to compute the node feature specifications. The network topology diagram of standard mutual citation relationship was drawn using Netdraw 2.054. RESULTS: A total of 269 national occupational health standards were included, involving 361 normative references files. Among them, the highest degree centrality was 48.064 in GBZ/T 251 Guidelines for Prevention and Control of Occupational Hazard in Foundry of Automobile Manufacturing. The highest closeness centrality and betweenness centrality were 27.386 and 33.210, respectively, in GBZ 2.1 Occupational Exposure Limits for Hazardous Agents in the Workplace--Part 1 : Chemical Hazardous Agents. The topographic map of standard mutual reference network indicated that five national occupational health standards were located in the central position of the mutual reference network, which included GBZ 1 Hygiene Standards for the Design of Industrial Enterprises, GBZ 2.1 Occupational Exposure Limits for Hazardous Agents in the Workplace--Part 1: Chemical Hazardous Agents, GBZ 2.2 Occupational Exposure Limits for Hazardous Agents in the Workplace--Part 2: Physical Agents, GBZ 158 Warning Sign for Occupational Hazards in the Workplace and GBZ 159 Specifications of Air Sampling for Hazardous Substances Monitoring in the Workplace. CONCLUSION: The five national occupational health standards located in the central position of the mutual reference network were the key nodes that have a greater influence on other standards, and can be the focus of future standard management.

ABSTRACT

Lung cancer is a malignant tumor characterized by a rapid proliferation rate, less survivability, high mortality, and metastatic potential. This review focuses on updated research about the clinical application of traditional Chinese medicine (TCM) as an adjuvant therapy to lung cancer treatment and the mechanisms of TCM effect on lung cancer in vitro and in vivo. We summarized the recent 5 years of different research progress on clinical applications and antitumor mechanisms of TCM in the treatment of lung cancer. As a potent adjuvant therapy, TCM could enhance conventional treatments (chemotherapy, radiation therapy, and epidermal growth factor receptors [EGFRs] tyrosine kinase inhibitors [TKIs]) effects as well as provide synergistic effects, enhance chemotherapy drugs chemosensitivity, reverse drug resistance, reduce adverse reactions and toxicity, relieve patients' pain and improve quality of life (QOL). After treating with TCM, lung cancer cells will induce apoptosis and/or autophagy, suppress metastasis, impact immune reaction, and therapeutic effect of EGFR-TKIs. Therefore, TCM is a promisingly potent adjuvant therapy in the treatment of lung cancer and its multiple mechanisms are worthy of an in-depth study.

ABSTRACT

The enzymes CYP1 A2 and CYP3 A4 were measured by building a "Cocktail" probe drug and the incubation system of liver microsomes. The compatibility of Aconiti Lateralis Radix Praeparata combined with dried Rehmanniae Radix on CYP450 enzyme protein and gene expression was explored from the level of protein and molecular biology. It explored the molecular mechanism of compatibility detoxication of Aconiti Lateralis Radix Praeparata to provide scientific support for clinical safe and effective application of Aconiti Lateralis Radix Praeparata. The CYP450 enzyme activity was determined by using "Cocktail" probe drugs. The content of CYP450 enzyme was measured by CO reduction of differential spectrum method. The mRNA expression of CYP1 A2 and CYP3 A4 enzyme was detected by RT-PCR technology. Compared with the blank group, the CYP1 A2 and CYP3 A4 enzyme activity and mRNA expression were increased in the dried Rehmanniae Radix combined with Aconiti Lateralis Radix Praeparata group with significant differences(P<0.05), while the CYP3 A4 enzyme activity and mRNA expression were no influence in the Aconiti Lateralis Radix Praeparata group. The CYP3 A4 enzyme activity and mRNA expression were increased in the dried Rehmanniae Radix and the dried Rehmanniae Radix combined with Aconiti Lateralis Radix Praeparata group, and there were significant differences(P<0.05). The content of CYP450 enzyme was decreased in the Aconiti Lateralis Radix Praeparata group, contributed to extremely significant difference(P<0.01). The content of CYP450 enzyme was increased in the dried Rehmanniae Radix and the dried Rehmanniae Radix combined with Aconiti Lateralis Radix Praeparata group, and there were significant differences(P<0.05). The CYP1 A2 and CYP3 A4 enzyme activity and gene expression were enhanced after dried Rehmanniae Radix combined with Aconiti Lateralis Radix Praeparata. The metabolism of toxic ingredients of Aconiti Lateralis Radix Praeparata was accelerated to reach an effect of detoxication. The detoxication mechanism of compatibility of Aconiti Lateralis Radix Praeparata was verified from the viewpoint of liver metabolic enzymes.

ABSTRACT

OBJECTIVE@#To investigate the influence of iron deficiency on the index of thalassemia screening.@*METHODS@#876 blood samples of the couples at childbearing age, who underwent red blood cell analysis, hemoglobin electrophoresis, ferritin and gene diagnosis were selected. The samples were divided into normal, iron deficiency, αthalassemia, α-thalassemia combining with iron deficiency, β-thalassemia and β-thalassemia combining with iron deficiency group. The differences of hematology index and hemolobin value A2 between each groups were analyzed.@*RESULTS@#The value of Hb, MCV, MCH, MCHC in iron deficiency, αthalassemia, α-thalassemia combining with iron deficiency, β-thalassemia and β-thalassemia combining with iron deficiency group all were lower than that of normal group, while the value of RDW-CV was higher, in which the difference between β-thalassemia was the highest. The distribution of HbA2 among each groups was not significantly different expect of β-thalassemia. There was no significant correlation between HbA2 and ferritin level.@*CONCLUSION@#RDW-CV increases in both iron deficiency and thalassemia. Iron deficiency has no significant effect on the level of hemoglobin A2.

ABSTRACT

OBJECTIVE@#To explore the abnormal hemoglobinopathy in couples of child-bearing age in Chongqing.@*METHODS@#A total of 34 800 subjects of child-bearing age were screened for thalassemia by using capillary electrophoresis from January 2015 to September 2018. PCR-flow cytometry fluorescence hybridization assay was used to detect the common thalassemia gene deletions and mutations.@*RESULTS@#8 kinds of abnormal hemoglobinopathy were detected in 200 cases from 34 800 subjects of child-bearing age, the detection rate was 0.57% in couples of child-bearing age in Chongqing: Among 200 cases of abnormal hemoglobin pathy, Hb E was found in 90 cases (accounting for 45.0%), and Hb D in 25 cases (accounting for 12.5%). Hb NewYork was found in 25 cases (accounting for 12.5%). HbJ-bangkok was found in 25 cases (accounting for 12.5%), and Hb Q-Thailand in 16 cases (accounting for 8.0%). Hb Hope was detected in 15 cases (accounting for 7.5%). Hb S was detected in 3 cases (accounting for 1.5%). Hb Hasharon was detected in 1 case (accounting for 0.5%). The mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) of Hb E and Hb Q-Thailand were lower than normal reference intervals.@*CONCLUSION@#The detection rate of abnormal hemoglobinopathy in Chongqing is higher than the average level in China. Capillary electrophoresis can effectively screen abnormal hemoglobinopathy, which is great significant for aristogenesis and improvement of population quality.

ABSTRACT

Notoginseng Radix et Rhizoma, one of precious and important traditional Chinese medicinal herb, has the functions of dispersing blood stasis and stopping bleeding, detaching swelling and alleviating pain, and invigorating Qi and blood. It is a traditional Chinese medicine for promoting blood circulation and removing blood stasis. After processing, the efficacy of Notoginseng Radix et Rhizoma was obviously different, the raw products mainly dispersed blood stasis and hemostasis, while the main effect of processed products was to replenish blood and Qi. In recent years, more attention has been paid to Notoginseng Radix et Rhizoma research, mainly focusing on the chemical constituent, pharmacological action and clinical application of the raw products. Although the research on processed Notoginseng Radix et Rhizoma has been increasing in these years, the mechanism of processing and the changes of bioactive constituents before and after processing are still unclear. This paper systematically summarized the modern processing methods of Notoginseng Radix et Rhizoma and compared the changes in chemical constituent and pharmacological action before and after processing through literature search. It is proposed that modern technologies should be put forward to study the correlation between the chemical constituent transformation and enriching blood as the breakthrough point, in order to explain the processing mechanism of Notoginseng Radix et Rhizoma, improve the quality evaluation system of this decoction pieces, and provide guarantee for the safety and effectiveness of its clinical medication.

ABSTRACT

OBJECTIVE: To explore the effects of Jiedu-jiangzhuo granules on gut microbiota of metabolic syndrome rats and TLR4/NF-κB pathway. METHODS: SD rats were randomly divided into normal control group, model group, metformin group, experimental high-dose of Jiedu-jiangzhuo granules 2.4 g•kg-1•d-1 group and experimental low-dose of Jiedu-jiangzhuo granules 1.2 g•kg-1•d-1 group, with 12 rats in each group. Except for rats in the control group, the other rats were fed with high-fat/ sugar/salt diet for 12 weeks. When fed for 8 weeks, the rats in metformin group (0.103 g•kg-1•d-1), experimental high-dose group (2.4 g•kg-1•d-1) or experimental low-dose group (1.2 g•kg-1•d-1) were simultaneously gavaged with metformin or Jiedu-jiangzhuo granules for 4 weeks. Body weight, serum lipid indexes and lipopolysaccharide(LPS) were determined by biochemical method, liver coefficient and epididymal fat tissue coefficient of rats were detected. Total genomic DNA of gut microbiota was extracted from fecal samples, then DNA library was built. Community structures of fecal microbes and α-diversity were sequenced on the Illumina Miseq platform. RESULTS: At the end of experiment, the body weight, LPS, serum total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C) and fasting blood glucose(FBG) of rats in experimental high-dose group were lower than those in the model group and higher than those in the control group (P0.05). The liver coefficient and epididymal fat tissue coefficient of rats in experimental high-dose group were lower than those in the model group (P0.05). Besides, the NF-κB, IL-6, TNF-α levels of rats inexperimental high-dose group were lower than those in the model group, metformin group or low-dose group (P0.05). Chaol index of gut microbiota was higher than that in the other four groups (P0.05). The ratios of Firmicutes, Proteobacteria, Actinobacteria, Tenericutes and Prevotella, Phascolarctobacterium in experimental high-dose group were lower than those in model group (P<0.05), meanwhile the ratios of Bacteroidetes, Paraprevotella and Bacteroides were higher than those in model group (P<0.05). Finally, TLR4 and NF-κB proteins in colonic tissues of rats in experimental high-dose group were lower than those in model group(P<0.05). CONCLUSION:S There are significant evidences that Jiedu-jiangzhuo granules could play a role in lower of weight gain and blood lipids in metabolic syndrome rats by adjusting the gut microbiota and TLR4/NF-κB pathway.

ABSTRACT

The Chinese softshell turtle exhibits ZZ/ZW sex determination. To identify the sex of embryos, juvenile and adult individuals, we designed two pairs of polymerase chain reaction primers, SB1-196, which amplifies a fragment of 196 bp in the female and the other, CK1-482, which amplifies the 482-bp fragment in both the sexes. It is validated in 24 adult turtles of known sex, sampled from three different locations. This one-step sexing technique is rapid and easy to perform and is reported for the first time.
