Obesity， a global chronic disease， is associated with adipose tissue dysfunction， which is one of the contributing factors to obesity. The cyclic adenosine monophosphate （cAMP） signaling pathway， a key regulator of lipid metabolism， plays a pivotal role in obesity development. Various of traditional Chinese medicine monomers， such as flavonoids， lignans， phenols， and terpenoids， as well as traditional Chinese medicine compound formulas like Xiaoyao powder， Shengmai powder， and Zexie decoction， can maintain energy homeostasis， balance adipose tissue function， regulate glucose metabolism， improve insulin resistance， and suppress inflammatory responses through cAMP signaling pathway regulation， thereby intervening in lipid metabolism for obesity treatment. Although a substantial amount of basic research has preliminarily elucidated the potential mechanisms by which traditional Chinese medicine intervenes in obesity through the cAMP signaling pathway， clinical translational research remains inadequate. There is an urgent need for large-sample， high-quality randomized controlled trials to validate these findings.

ObjectiveTo investigate the expression level of mammalian sterile 20-like kinase 1 （MST1） in prostate cancer （PCa） tissues， its biological functions， and its regulatory effects on androgen receptor （AR） and vascular endothelial growth factor （VEGF） expression. MethodsImmunohistochemistry was performed to detect MST1 expression in 77 prostate cancer tissues and 34 benign prostatic hyperplasia （BPH） tissues， and the relationship between MST1 expression and clinicopathological parameters was analyzed. MST1-overexpressing C4-2 and LNCaP cell lines were constructed. CCK-8 assay， Transwell migration assay， and angiogenesis assay were conducted to evaluate the effects of MST1 on cell proliferation， migration， and angiogenesis. The expression changes of AR and VEGF were detected by qRT-PCR and Western blot. ResultsMST1 expression was significantly lower in PCa tissues compared with BPH tissues （P=0.012）. Low MST1 expression was significantly associated with tumor metastasis （P=0.033）. MST1 overexpression inhibited C4-2 cell proliferation and migration， with transmembrane migrated cells reduced by 53.6% （P<0.01）. MST1 overexpression decreased the mRNA and protein expression levels of AR and VEGF （P<0.05）. Angiogenesis assay demonstrated that the length of new vessel structure was significantly reduced （P<0.05）. ConclusionMST1 shows a low expression level in PCa tissues and is associated with tumor metastasis. MST1 exerts tumor-suppressive effects in prostate cancer by inhibiting cell proliferation， migration， and angiogenesis， as well as downregulating the expression of AR and VEGF， indicating its potential as a therapeutic target for prostate cancer.

Objective To explore the distribution characteristics and influencing factors of nasal colonized bacteria of healthcare workers(HCWs)in pediatric intensive care unit(PICU).Methods A cross-sectional study was con-ducted.Nasal swab specimens from 104 HCWs in the PICU of a hospital were collected for bacterial culture and an-timicrobial susceptibility testing.According to the identification and antimicrobial susceptibility testing results of strains,distribution characteristics of colonized bacteria was analyzed.Basic information of studied subjects were collected through questionnaire survey,and risk factors for colonized bacterial infection were conducted using logis-tic regression analysis.Results Among 104 specimens,colonized bacteria were detected from 66 specimens,with an overall detection rate of 63.46％.Gram-positive bacteria was mainly Staphylococcus aureus,with a detection rate of 34.62％(n=36),out of which methicillin-resistant Staphylococcus aureus(MRSA)accounted for 2.88％(n=3).Gram-negative bacteria was mainly Klebsiella spp.,with a detection rate of 21.15％(n=22).Multiva-riate logistic regression analysis showed that HCWs with junior professional titles(OR=11.400,95％CI:2.329-55.801,P=0.003)was an independent risk factor for Staphylococcus aureus colonization,and male(OR=4.260,95％CI:1.160-15.653,P=0.029)was an independent risk factor for Klebsiella spp.colonization.Conclusion Nasal cavity of HCWs in PICU has a high detection rate of colonized bacteria,with Staphylococcus aureus and Klebsiella spp.being the major colonized bacteria.

OBJECTIVE To explore the characteristics of hot flushes and the effect of Erxian Decoction in rats after bilateral oo-phorectomy.METHODS Forty-eight female SD rats were randomly divided into 4 groups:sham operation group,bilateral ovariecto-my group,17β-estradiol treatment group and Erxian Decoction treatment group,with 12 rats in each group.After bilateral ovariecto-my,rats were gavaged with 17β-estradiol(0.1 mg·kg-1·d-1)and Erxian Decoction(8 g·kg-1·d-1)for 6 weeks.On the 21st and 42nd days of modeling,the body weight,rectal temperature,infrared thermography of the body surface and other characteristic informa-tion of the rats were detected.Serum E2 content was detected by ELISA.The pathological changes of the uterus and foot pad sweat glands of the rats were observed by HE staining.The hypothalamic estrogen receptor(ER)and thermoreceptor transient receptor poten-tial vanilloid 3(TRPV3)and transient receptor potential vanilloid 4(TRPV4)were detected by immunohistochemistry.The protein ex-pression of ERβ,PAC1R and PKA was detected by Western blot.RESULTS Compared with the sham operation group during the same period,the body weight of the rats in the bilateral ovariectomy group increased significantly(P<0.01),while the body weight of the rats in the 17β-estradiol group and Erxian Decoction group increased slowly.Compared with the sham operation group,the rectal temperature of the bilateral ovariectomy group and the 17β-estradiol group increased significantly on the 21st day after modeling(P<0.01),and decreased significantly on the 42nd day after modeling(P<0.05);on the 21st and 42nd days after modeling,the maxi-mum body surface temperature of the rats in the bilateral ovariectomy group,the 17β-estradiol group and the Erxian Decoction group decreased significantly(P<0.01),and on the 42nd day after modeling,the tail/body temperature ratio of the rats in the bilateral ovari-ectomy group increased significantly(P<0.05);the number of sweat points in the bilateral ovariectomy group increased significantly(P<0.01);the uterine index of the bilateral ovariectomy group,the 17β-estradiol group and the Erxian Decoction group decreased sig-nificantly(P<0.01);the serum E2 in the bilateral ovariectomy group decreased significantly(P<0.05);the number of ER-positive cells in the hypothalamus of the rats in the bilateral ovariectomy group decreased significantly(P<0.01),while the number of TRPV3 positive cells increased significantly(P<0.05);the number of ER and TRPV3 positive cells decreased in the 17β-estradiol group(P<0.05),and the number of TRPV4 positive cells increased(P<0.01);17β-estradiol inhibited the expression of PAC1R and PKA pro-teins(P<0.05),and Erxian Decoction significantly inhibited the expression of PAC1R,PKA and ERβ proteins(P<0.01).Compared with the bilateral ovariectomy group,the rectal temperature of the Erxian Decoction group decreased significantly on the 21st day(P<0.01);the number of sweat spots in the 17β-estradiol group and the Erxian Decoction group decreased significantly(P<0.01);the E2 level in the Erxian Decoction group increased significantly(P<0.05),the number of ER positive cells in the hypothalamus increased significantly(P<0.01),and the expression of ERβ and PAC1R proteins decreased significantly(P<0.01).CONCLUSION Bilater-al oophorectomy rat model is associated with hot flashes,and its symptom characteristics are yin deficiency and internal heat,as well as insufficient yang qi,resulting in a yin-yang imbalance;Erxian Decoction affects the sensitivity of temperature changes by promoting es-trogen secretion and its receptor expression.

Objective To explore the relationship between the head injury criterion(HIC)values in anterior-posterior(AP)collisions and lateral-medial(LM)collisions.Methods A total of 102 male SD rats were randomly divided into a control group of 0 m(6 rats),4 AP groups(12 rats/group)and 4 LM groups(12 rats/group).After adaptive training,the classical Marmarou model was used to execute the brain AP and LM collisions under a series of different height impacts,and the HIC values were calculated.The experimental group data of the walk-pole test and grip strength test were collected at 24 hours before and after injury,and the data of the proportion of hemorrhage in the corpus callosum and pyramidal tracts were collected at 24 hours after injury.Results As the collision heights increased in both AP and LM groups,there were positive correlations with changes in WP test time and peak GS,and corresponding increases in the proportion of hemorrhage in the cc and py.According to the mathematical relationships between the comprehensive injury degrees and HIC values,it was found that at the same injury degree,LM-HIC value was less than AP-HIC value.A mathematical relationship between AP-HIC and LM-HIC was fitted based on the comprehensive injury degrees.At the same HIC,LM group experienced more severe injuries,and AP group was more tolerant to head collision.Conclusion The injury severity in LM group is greater than that of AP group at the same HIC.Preliminary results show there is a linear mathematical relationship between AP-HIC and LM-HIC.These results can be expected to expand the application scope of HIC and achieve an accurate assessment of the LM collision severity.

Objective To investigate the clinical effect of aribulin combined with vinorelbine+cisplatin(NP)regimen in the treatment of advanced breast cancer patients.Methods Eighty patients with advanced breast cancer were selected and divided into the conventional group(treated with chemotherapy using NP regimen)and the combined group(treated with aribulin combined with NP regimen),with 40 cases in each group.The clinical benefit rate(CBR),objective response rate(ORR)and overall efficacy of the two groups were compared.Patients were followed for 12 months.The progression-free survival(PFS)was recorded in the two groups of patients.Serum levels of vascular endothelial growth factor(VEGF)A,VEGFB and VEGFC before treatment and 4 cycles after treatment were detected by enzyme-linked immunosorbent assay(ELISA).Adverse reactions of patients were evaluated and graded according to common adverse event evaluation criteria.Results The ORR and CBR of the combined group were significantly higher than those of the conventional group,and the overall curative effect of the combined group was better than that of the conventional group(P＜0.05).PFS in the combination group was longer than that in the conventional group(P＜0.01).After treatment,the levels of VEGFA,VEGFB and VEGFC in the 2 groups were lower than those before treatment,and the levels in the combined group were significantly lower than those in the conventional group(P＜0.05).The main adverse reactions of 2 groups during treatment were grade Ⅰto Ⅱ,including neutropenia,gastrointestinal reaction,peripheral nerve abnormality,fatigue,liver function injury and alopecia,with no statistical significance.Conclusion Aribulin combined with NP regimen in the treatment of advanced breast cancer can increase CBR and decrease VEGF expression level,with good safety.

(Peri)Menopausal insomnia is one of the most common symptoms experienced by women in(peri)menopausale,and can cause varying degrees of damage to both the physical and mental health of individuals.Modern medicine believes that the decline in estrogen levels and the imbalance in estrogen receptor expression are closely related to the occurrence of(peri)menopausale insomnia in women.Traditional Chinese Medicine believes that the imbalance of yin and yang in the body,caused by the disharmony between the heart and kidney,is an important factor in the onset of this disease.Professor Xiao Chengcong,a renowned master of traditional Chinese medicine,has summarized years of clinical experience and has developed a unique therapeutic approach for this disease using the harmonizing method.Her self-designed empirical formula,Gengxin Decoction,has been proven to have a good therapeutic effect in clinical trials.The team has further confirmed in animal studies that Gengxin Decoction can increase estrogen levels,promote estrogen receptor expression in the hypothalamus,influence the regulation of monoamine neurotransmitters,enhance the negative gene expression of the biological clock,reduce brain excitability,and restore the circadian rhythm of the biological clock.This article discusses the decline in estrogen levels and the imbalance in estrogen receptor expression which promote the occurrence and development of(peri)menopausal insomnia,the role of Gengxin Decoction and the harmonizing method in the etiology and pathogenesis of(peri)menopausal insomnia,and the alignment between the physiological effects of Gengxin Decoction and the balance of estrogen levels and estrogen receptor expression,aiming to reveal the scientific connotation of Professor Xiao Chengcong's use of the harmonizing method to treat(peri)menopausal insomnia,to provide a reference for clinical treatment,and to promote the dissemination and inheritance of the academic thoughts of traditional Chinese medicine master Professor.

Objective:To study the effects of hypoxia on the autophagy level in the spleen of mice with OSAHS.Methods:Mouse OSAHS hypoxia model was established in 24 C57BL/6 mice and the mice were divided into 3 groups:normoxic group,hypoxic group and resveratrol group(n=8).Real time PCR,Western blot and immunohistochemical staining(IHC)were used to detect the mRNA and protein expression of autophagy related proteins microtube associated protein 1 light chain 3 B(LC3B),myosin-like BCL2 inteacting protein(Beclin1)and autophagy related gene 5(ATG5)in mouse spleen respectively.Results:The mRNA expres-sion of LC3B,Beclin1,and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001),resveratrol upregulated the expression levels of LC3B and ATG5 mRNA in the hypoxic group(P＜0.05,P＜0.001),but did not up-regulate the expression of Beclin1(P＞0.05).The protein expression levels of LC3B,Beclin1 and ATG5 in the hypoxic group were lower than that in the normoxic group(P＜0.05,P＜0.05,P＜0.01).Resveratrol upregulated the expression levels of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulated the expression of Beclin1(P＞0.05).IHC test showed that the expression level of LC3B,Beclin1 and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001).Resveratrol increased the expression level of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulate the expression of Beclin1(P＞0.05).Conclusion:Hypoxia may inhibite the autophagy level of spleen in mice.Resvera-trol derivatives increases the autophagy level of mice under hypoxia condition,but has no significant effect on Beclin1 expression.

In the pathological process of acute lung injury,uncontrolled inflammatory response will lead to severe consequences,and pyroptosis plays a vital factor in a cell programmed inflammatory necrosis.When the body is imbalanced due to excessive pyroptosis,it can lead to lung injury in the lungs.TCM emphasizes the balance of the body and the balance of yin and yang.Based on the"yin-yang"theory and"pathogenic factors and healthy qi"theory of TCM,this article discussed the yin-yang changes,growth and decline,and opposing constraints of cell pyroptosis in the occurrence and development of acute lung injury at the cellular level,and explained the possible basis of TCM in preventing and treating cell pyroptosis,providing theoretical reference for the intervention of TCM in the prevention and treatment of acute lung injury with cell pyroptosis.
