Objective:To investigate the relationship between protein tyrosine phosphatase non-receptor type 1 (PTPN1) gene polymorphism and the risk of gestational diabetes mellitus (GDM).Methods:In this case-control study, 4 835 pregnant women who delivered from March, 2012 to July, 2014 in the Department of Gynecology and Obstetrics at the First Hospital of Shanxi Medical University were consecutively enrolled. Among them, 789 cases were diagnosed with GDM. A simple random sampling method was used to select 334 pregnant women with GDM as the case group, and 334 healthy pregnant women matched by maternal age, gestation time and residence were set as control. The DNA genotyping was performed in the subjects, and those with genotyping deletions10% were excluded; and finally, 322 and 317 subjects were included in case and control group, respectively. Under the codominant, dominant, recessive, and allelic genetic models, the unconditional logistic regression model was used to check the relationship between 13 candidate single nucleotide polymorphism (snp) loci in PTPN1 gene and the risk of GDM. The Haploview was used to analyze the relationship between haplotypes and risk of GDM, and multiple comparisons were adjusted with the false discovery rate (FDR) method.Results:The age of the 639 pregnant women analyzed in this study was (30.28±4.32) years. The proportions of pre-pregnancy body mass index (BMI)≥24.0 kg/m 2 and having a family history of diabetes were significantly higher in the GDM group compared to those in the control group (29.19% vs 16.72% and 13.04% vs 6.31%, respectively, both P0.05). The rs6096644 locus was positively associated with increased risk of GDM in co-dominant (GG vs AA, OR=2.76, 95% CI: 1.18-6.44) and recessive (GG vs AA+AG, OR=2.78, 95% CI: 1.20-6.46) genetic models (all q0.2). The rs6096655 locus was positively associated with increased risk of GDM in codominant (AA vs GG, OR=5.90, 95% CI: 1.27-27.36) and recessive (AA vs GG+GA, OR=5.50, 95% CI: 1.19-25.38) and alleles (A vs G, OR=1.51, 95% CI: 1.09-2.08) genetic models (all q0.2). The rs6013317 locus was associated with an increased risk of GDM in the allele (A vs G, OR=1.74, 95% CI: 1.15-2.63) genetic model (all q0.2). The GAGG haplotype and GGAG haplotype in haplotype block 1 (rs4811262, rs6096646, rs6096655, rs6013317), and the GGGA haplotype in haplotype block 2 (rs6068018, rs6123105, rs6013324, rs2869621) of the PTPN1 gene were all positively associated with an increased risk of GDM (all P0.05). Conclusion:PTPN1 gene polymorphisms may associated with risk of GDM, moreover, complex haplotype structures within the gene influence the risk of GDM.

ObjectiveTo investigate the effect of modified Weijingtang on the pyroptosis of RAW264.7 macrophages via the cysteinyl aspartate-specific protease-1 （Caspase-1）/gasdermin D （GSDMD） pathway. MethodLipopolysaccharide （LPS） was used to induce pyroptosis of RAW264.7 cells. The blank group was treated with the blank serum， and the intervention groups were treated with the sera containing different doses of modified Weijingtang. After 24 h， the viability of cells in different groups was examined by the cell counting kit-8 （CCK-8）. The pyroptosis and morphology of cells in each group were observed by a scanning electron microscope and a phase-contrast microscope， respectively. The mRNA and protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3）， Caspase-1， and GSDMD in each group were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The levels of interleukin （IL）-18 and IL-1β in each group were measured by enzyme-linked immunosorbent assay. ResultUnder the electron microscope， RAW264.7 cells presented the best morphology and structure in the blank group and obvious pyroptosis and leakage of cell contents in the model （LPS） group. Compared with the model group， the intervention groups showed reduced pyroptosis to varying degrees， and the high-dose group had the closest cell morphology and structure to the blank group. Under the optical microscope， RAW264.7 cells were spherical in the blank group and irregular with protrusions in the model group. Compared with the model group， the intervention groups showed improved cell morphology， and the cell morphology in the group with the dose of 20% was the closest to that in the blank group. The mRNA and protein levels of NLRP3， Caspase-1， and GSDMD in the model group were higher than those in the blank group （P<0.05）. Compared with the model group， each intervention group showed down-regulated expression of the above indicators （P<0.05）. Compared with the blank group， the model group presented elevated levels of IL-18 and IL-1β （P<0.05）， which were lowered in the intervention （10%， 20%） groups （P<0.01）. ConclusionModified Weijingtang inhibits the pyroptosis of macrophages by down-regulating the Caspase-1/GSDMD pathway and reducing the release of proinflammatory cytokines.

By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.

Objective To investigate the role of lipopolysaccharide(LPS)in regulating the inflammatory response of neutrophil through the leucine-rich α-2 glycoprotein 1(LRG1)/Rho-associated protein kinase(ROCK1)signaling.Methods HL-60 cells were treated with 1 μmol/L all-trans retinoic acid(ATRA)and 12.5 μL/mL dimethyl sulfoxide(DMSO)for 72 h and 96 h,and the morphological changes were observed by Wright-Giemsa staining.The expression of CD11b was detected by flow cytometry.LPS induced the activation of dHL-60 and human peripheral blood neutrophils.The transcription and secretion levels of LRG1,ROCK1 and inflammatory cytokines were detected by qPCR and ELISA,respectively.The expression levels of LRG1 and ROCK1 after the activation of dHL-60 were detected by Western blotting.Furthermore,dHL-60 was treated with the recombinant protein LRG1 and ROCK1 inhibitor Y-27632;the transcription levels of inflammatory cytokines were detected by qPCR.Results Neutrophils were activated by LPS.The expression levels of LRG1 and ROCK1 were significantly increased,and the transcription levels of inflammatory cytokines were significantly increased.The recombinant protein LRG1 activated dHL-60 in vitro,and the transcription levels of ROCK1 and inflammatory cytokines were significantly increased.Using the ROCK1 inhibitor Y-27632,the production levels of inflammatory cytokines were significantly reduced.Conclusion LPS can regulate the production levels of neutrophil inflammatory cytokines through activating the LRG1/ROCK1 signaling,thus exacerbating the inflammatory response.

Objective To analyze the relationship between the fat content of supraspinatus muscle measured by spectral CT fat-muscle material decomposition technology and the tendon tear severity(TTS)of supraspinatus,as well as shoulder joint function.Methods A total of 108 patients were prospectively selected to undergo routine MRI and spectral CT imaging of the shoulder joints.The patients were divided into normal,degenerative,partial tear,and full-thickness tear groups based on MRI findings.A fat-muscle material decomposition image was generated through spectral analysis to measure the fat content of supraspinatus muscle.The differences in fat content of supraspinatus muscle between the groups were compared,and correlation analyses were performed between the fat content of supraspinatus muscle and the clinical baseline characteristics,symptom duration,and Constant-Murley scores in patients with supraspinatus tendon tears.Results Comparison of supraspinatus muscle fat content among the four groups:the full-thickness tear group＞the partial tear group＞the degenerative group＞the normal group(P＜0.05).There was a strong positive cor-relation between the supraspinatus muscle fat content and the supraspinatus TTS(r=0.654,P＜0.05).Among patients with partial and full-thickness tears of the supraspinatus tendon,there was a moderate positive correlation between supraspinatus muscle fat content and patient age(r=0.393,P＜0.05),a weak positive correlation with gender(r=0.199,P＜0.05),with higher fat content observed in females compared to males,no significant correlation with symptom duration(r=0.037,P＞0.05),a moderate positive correla-tion with body mass index(BMI)(r=0.463,P＜0.05),and a moderate negative correlation with Constant-Murley score(r=-0.316,P＜0.05).Conclusion In patients with rotator cuff tears,the quantitative fat content of supraspinatus muscle based on spectral CT fat-muscle material decomposition technology is strongly positively correlated with rotator cuff injury degree,and is also correlated with patient age,gender,BMI,and the strength of the shoulder joint muscles and range of the motion.

OBJECTIVE: To study the molecular epidemiology of thalassemia in Jiaxing area of Zhejiang province and provide a basis for prenatal diagnosis, genetic counseling and prevention and control of birth defects. METHODS: A total of 24 003 pregnant women who presented at the Jiaxing Maternal and Child Health Care Hospital from April 2017 to September 2021 were enrolled. Capillary hemoglobin electrophoresis in combination with routine blood test were used for primary screening for carriers of thalassemia-associated mutations, and those with positive results were subjected to fluorescence quantitative PCR assay. Prenatal diagnosis was provided for couples with a risk of giving birth to children with intermediate or severe thalassemia. RESULTS: Among the 24 003 pregnant women, 1 211 cases were suspected as carriers of thalassemia-associated mutations, among whom 443 (36.58%) were confirmed by genetic testing. Among these, carriers of α-, β- and α-complex β-globin gene mutations have accounted for 27.31% (121/443), 70.65% (313/443) and 2.04% (9/443), respectively. The result of prenatal diagnosis for an at-risk couple was --SEA/αCSα, and the fetus was predicted to have intermediate or severe thalassemia. Termination of the pregnancy was recommended. CONCLUSION Hemoglobin electrophoresis combined with routine blood test during pregnancy may be used as a preliminary screening measure for carriers of thalassemia-associated variants. Combined with genetic testing, this will be of great significance for the control of thalassemia in this region.
