Objective To explore the relationship of professional stress,social support and somatic symptoms of sub-health status of Ningbo normal senior school teachers. Methods 128 normal senior school teachers were selected and investigated by professional stress scale,social support scale and somatic symptoms of sub-health status scale, and canonical correlation analysis was used. Results The canonical correlation coefficient were 0.563, 0.471( P <0.01) with the existence of social support variable. The somatic symptoms of sub-health status would be greater with the rise of their professional stress and the decline of their social support. The canonical correlation coefficient was 0.497( P <0.01) with the elimination of social support variable. The factor loading of "examination pressure","professional burden" and "career expectation" in canonical variable ξ add to 0.801,0.855,0.726 respectively. The factor loading of "feeling of fatigue","sleep disorders" in canonical variable η add to 0.774,0.859 respectively. Conclusion The social support have adjustment function between the professional stress and somatic symptoms of sub-health status.

Objective To investigate the expression profile variation of long non-coding RNAs (lncRNAs) in ankylosing sporidylitis (AS) and explore the role of lncRNAs in the pathogenesis of AS.Methods The peripheral blood mononuclear cells of AS patients and health controls (HC) were used to detect for differently expressed lncRNAs by microarray.The roles of lncRNAs were predicted with GO and pathway analysis.The results were verified by real time-polymerase chain reaction (PCR).Results A total of 148 lncRNAs and 134 mRNAs were detected,which had more than 2-fold differentially expressed in AS patients.Bioinformatics analysis found that GO term enrichment included protein binding,regulation of transcription,metabolism,signal transduction,et al.and might involve in toll-like receptor pathway,protein kinase,complement pathway,notch signaling pathway and so on.The expressions of three lncRNAs were estimated by real time-PCR which found that consistent with that of microarrays.Among these,D90064 was the most aberrantly expressed lncRNAs.Conclusions Several lncRNAs expression was changed significantly in AS patients in comparison with HC,which implies that those different lncRNAs may have an important role in the development and progression of AS.

OBJECTIVEQingkailing injection (QKLI), Jinnaduo injection (JNDI), Shuxuetong injection (SXTI), Shenmai injection (SMI) and Kangai injection (KAI) are widely used in China. To predict the herb-drug interactions in clinical application, they were evaluated for their in vitro inhibition effect on CYP3A in rat liver microsomes.

METHODThe rat liver microsomes were incubated with different doses of 5 kinds of traditional Chinese medicine injections (TCMIs) in the present of testosterone, a specific substrate of CYP3A. 6beta-hydroxytestosterone, the metabolite of testosterone, was monitored by HPLC to compare the inhibition effect of 5 TCMIs on CYP3A in rat liver microsomes. Ketoconazole was used as a positive control.

RESULT10% QKLI reduced the formation of 6beta-hydroxytestosterone by approximately 93.0%, which is more significant than other four TCMIs. The half maximal inhibitory concentration (IC50) and the enzyme-inhibitor constant K(i) were 1.0% and 0.7% respectively.

CONCLUSIONQKLI showed much stronger inhibition activity against CYP3A, comparing to other 4 TCMIs. The results revealed that QKLI may be involved in herb-drug interactions by inhibition of CYP3A.

Cancer is a severe threat to human life and health.The over-activation of oncogenes is the main reason for poor treatment and prognosis of cancer patients.Most of these over-activated oncogenes are protein tyrosine kinase(PTK).Among many PTKs,non-receptor tyrosine kinase(NRTK)is an important signaling molecule that regulates cell proliferation and migration as the primary driver of intracellular signaling pathway transduction.Targeting NRTK has become the focus and difficulty in developing anti-tumor drugs.Traditional Chinese medicine(TCM),with its characteristics of multi-channel,multi-link,multi-target,and low toxicity,plays a significant advantage in treating adjuvant tumors.So far,it has been found various traditional TCM monomers can inhibit NRTK from playing an anti-tumor role.This review summarized the part of Src,Jak,Abl,Fak families,the prominent members of NRTK in tumor progression,as well as the TCM monomers acting on these members.We aimed to provide a theoretical basis for the anti-tumor therapy targeting NRTK and a reference for the search for TCM monomer inhibitors of NRTK.

OBJECTIVE To mine the safety signals of FOLFOX scheme and FOLFIRI scheme-induced hepatotoxicity， and to provide reference for the selection of clinical rational treatment plan and the prevention and treatment of drug adverse reaction （ADR）. METHODS Reporting odds ratio method and proportion report ratio method were used to analyze adverse drug event （ADE） reports of FOLFOX scheme and FOLFIRI scheme in FDA adverse event reporting system during January 1， 2004-June 30， 2022. The potential safety signals of FOLFOX scheme and FOLFIRI scheme-induced hepatotoxicity were mined. RESULTS The amounts of ADE reports related to FOLFOX scheme and FOLFIRI scheme were respectively 3 454 and 1 359； the proportions of male and female patients involved were 1.50∶1 and 1.67∶1 in these two schemes， respectively. The top five countries with the largest number of reports were the United States， Japan， France， Italy and the United Kingdom， respectively accounting for 58.48% and 53.79% of the total reported cases. More than 90% of patients took no more than 5 drugs in combination， the proportion of patients receiving FOLFOX scheme and FOLFIRI scheme combined with anti-angiogenic drugs or epidermal growth factor receptor inhibitors was 45.45% and 86.82%， respectively. Totally 443 ADE reports of FOLFOX scheme-induced hepatotoxicity were collected， and 22 ADR signals were generated， including hepatic sinusoidal obstruction syndrome， nodular regenerative hyperplasia， drug-induced liver injury， blood bilirubin increased， etc. Totally 128 ADE reports of FOLFIRI scheme- induced hepatotoxicity were reported， and 9 ADR signals were generated， including blood bilirubin increased， hepatotoxicity， steatohepatitis， hepatic steatosis， etc. CONCLUSIONS FOLFOX scheme and FOLFIRI scheme can cause different types of hepatotoxicity. Clinical drug monitoring should be strengthened to guarantee drug safety.

Objective To investigate the effects and potential mechanisms of Marsdeniae Tenacissimae Caulis(Tongguanteng)injection and extract in human osteosarcoma cells proliferation,migration,invasion,and apoptosis.Methods MNNG/HOS,Saos-2 osteosarcoma cells,and normal bone marrow mesenchymal stem cells(BMSC)were cultured in vitro.Cells were incubated with different concentrations of Tongguanteng injection and Tongguanteng extract(40,60,80 mg/mL).Cell proliferation was evaluated by CCK-8 assay and plate colony formation assay.Cell migration and invasion were evaluated by scratch assay and Transwell assay.Cell apoptosis was evaluated by Hoechst33342 staining and Annexin-V/PI double staining assay.Bax,Bcl-2 and Caspase-3 mRNA expression were detected using RT-qPCR.The protein expressions of JAK1,p-JAK1,STAT3,p-STAT3 and MMP9 were detected by Western blot.Results Compared with the control group,both Tongguanteng injection and extract significantly decreased the survival rate of MNNG/HOS and Saos-2 cells,inhibited cell clone formation,migration,and invasion,induced cell apoptosis(P<0.05,P<0.01),promoted Bax mRNA and protein expression,inhibited Bcl-2 mRNA and protein expression,and up-regulated Caspase-3 mRNA and Cleaved Caspase-3 protein expression.Tongguanteng injection could significantly down-regulate the expressions of p-JAK1,p-STAT3 and MMP9 protein expression in Saos-2 cells(P<0.05,P<0.01).Conclusion Both Tongguanteng injection and Tongguanteng extract can significantly inhibit proliferation,migration and invasion of human osteosarcoma MNNG/HOS and Saos-2 cells,and induce apoptosis,with no significant difference in anti-tumor effect.The mechanism may be related to the inhibition of the activation of JAK1/STAT3 signaling pathway.

Objective:To explore the effects of periodontitis and inflammatory factors toward the occurrence of gestational diabetes mellitus (GDM).Methods:Pregnant women who came to the Department of Obstetrics, Northwest Women′s and Children′s Hospital for prenatal examinations during March to November of 2021 were invited to participate in this study. Participants with GDM who met the inclusion criteria ( n=100) were assigned into the case group; while healthy participants ( n=100) were assigned into the control group. Information of participants from the two groups were collected by questionnaires and periodontal statuses were clinically recorded in the meantime. Gingival crevicular fluid (GCF) and venous blood were also collected from participants of two groups to analyze the expression levels of inflammatory factors like C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, IL-8, IL-10 and IL-33. Factors different between the two groups were included in the multivariate regression analysis model to determine the risk factors of GDM. Results:The age of participants was (33.4±5.1) years in case group and (30.5±4.5) years in control group respectively, which had statistical differences ( t=4.33, P<0.001). Besides, the body mass index of participants from case group was also significantly higher than control group [(28.11±3.85) kg/m 2vs. (23.31±3.15) kg/m 2, t=9.65, P<0.001]. Participants with GDM had more adverse periodontal clinical parameters. Prevalence of periodontitis in GDM group was 47.0% (47/100) compared with 29.0% (29/100) in control group (χ2=6.88, P=0.009). Multivariate regression analysis results indicated that periodontitis was a critical risk factor for the occurrence of GDM ( OR=1.882, P<0.001). Besides, GCF IL-8, serum TNF-α, IL-8 and IL-10 were also risk factors of GDM due to their higher expressions. Among them, TNF-α in serum ( OR=2.077) and IL-8 in serum ( OR=2.060) had more significant impacts ( P<0.001). Conclusions:This study demonstrated that periodontitis was associated with the occurrence of GDM. Up-regulation of serum pro-inflammatory mediators leaded by local periodontal inflammatory microenvironment might play a critical role in this pathological process.

Paclitaxel is the first-line chemotherapy drug for a variety of cancers. However， the paclitaxel resistance greatly reduced the efficacy in the later treatment stage， which seriously increased the mortality and recurrence rate of cancer and limited the clinical application of paclitaxel. At present， Chinese medicine compound prescription， proprietary Chinese medicine， and Chinese medicine injection are widely used as the adjuvant chemotherapy drugs for the treatment of cancer in clinic. Chinese medicine has shown unique advantages in improving the efficacy of chemotherapy drugs and the prognosis of chemotherapy， and reducing the toxic and side effects. However， the specific mechanism and effective monomer composition of Chinese medicine for reversing the resistance of chemotherapy drugs are unclear， and the application of Chinese medicine in different types of cancer is also limited， which are worthy of further exploration. This review summarized the composition of Chinese medicine monomer with synergistic antitumor effect combined with paclitaxel in recent years. The specific mechanism and pharmacological activities of Chinese medicine monomer reversing paclitaxel resistance were classified. This review found that through acting on the membrane transport protein， Chinese medicine monomer promoted the accumulation of paclitaxel in tumor cells， inhibited the expressions of protein and metabolic enzyme related to multidrug resistance and the metabolism of paclitaxel， and regulated the levels of apoptosis genes and factors and apoptosis-related pathways to promote the inhibitory effect of paclitaxel on cell proliferation. Chinese medicine monomer also significantly improved paclitaxel chemotherapy sensitivity by regulating the expression levels of micro ribonucleic acid （microRNA） and long non-coding ribonucleic acid RNA （lncRNA）， inhibiting the characteristics of tumor stem cells and tumor metabolic reprogramming， improving tumor microenvironment， and triggering tumor cell death autophagy and oxidative stress response. This review provides a theoretical basis for clarifying the specific anti-tumor mechanism of Chinese medicine monomer combined with paclitaxel， which is of great significance for the development of new Chinese medicine and the clinical research of the drugs combined with paclitaxel， and has certain value for the application of Chinese medicine combined with other chemotherapy drugs.
