Referring to ZHANG Xichun's experience in treating dysentery from cold-fire accumulation， the treatment of ulcerative colitis （UC） in this paper can be divided into three stages including cold-fire accumulation stage， excessive heat and putrid intestine stage， and healthy qi deficiency and pathogen lingering stage. For people with slippery and excess pulse in the cold-fire accumulation stage， Xiaochengqi Decoction （小承气汤） added with Baishao （Radix Paeoniae Alba） and Gancao （Radix et Rhizoma Glycyrrhizae） can be used for purgation， while those with deficient pulse， Huazhi Decoction （化滞汤） or Xieli Decoction （燮理汤） can be used. In the excessive heat and putrid intestine stage， Tongbian Baitouweng Decoction （通变白头翁汤） and Jiedu Shenghua Elixir （解毒生化丹） are suggested. In the healthy qi deficiency and pathogen lingering stage， it is advised to use Jiedu Shenghua Elixir added with Shanyao （Rhizoma Dioscoreae）， and Sanbao Porridge （三宝粥）. Additionally， the medication rules， dosage and administration characteristics of Huanglian （Rhizoma Coptidis）-Rougui （Cortex Cinnamomi）， Yadanzi （Fructus Bruceae）， Diyu （Radix Sanguisorbae）， Shanyao and Liuhuang （Sulphur） by ZHANG Xichun have been summarized with the help of modern pharmacological research， so as to provide new ideas for the treatment of UC by TCM.

Purpose To evaluate the carotid artery elasticity and the influencing factors in the offspring of early-onset type 2 diabetes mellitus by RF-data based quantitative analysis on vessel stiffness.Materials and Methods We continuously encrolled 63 offspring of type 2 diabetes mellitus,depending on the parental diagnostic age of diabetes they were divided into two groups:32 cases of early-onset offspring group,31 cases of late-onset offspring group.32 healthy volunteers who were matched for age,gender and body mass index,were selected as controls.Real-time intima-media thickness and RF-data based quantitative analysis on vessel stiffness were employed to evaluate common carotid intima-media thickness,displacement,diameter,hardness coefficient and pulse wave velocity.The differences among the groups were compared.Results The intima-media thickness,pulse wave velocity and hardness coefficient in early-onset offspring group were higher than late-onset offspring group(t=0.054-1.228,P＜0.05),and displacement was lower than late-onset offspring group(t=0.048,0.109,both P＜0.05).Conclusion Carotid artery stiffness in the offspring of diabetes mellitus patients is significantly higher than the control group.And the carotid elasticity of early-onset offspring group decreased more obviously than late-onset group.

The nasal swab samples of swine influenza(SI)suspected pigs were collected and tested for H3 subtype swine influenza virus(SIV)positive by RT-qPCR.The positive samples were inoc-ulated into SPF chicken embryos for virus isolation.The full genome sequencing and sequence anal-ysis of the isolated H3N2 subtype SIV were conducted,and its pathogenicity was studied.The re-sults showed that a strain of SIV was successfully isolated and identified as H3N2 subtype by RT-PCR,named A/Swine/Yunnan/KM/06/2023(H3N2).The BLSAT results showed that the eight segments of SIV H3N2 KM had the highest homology with eight different strains of swine influ-enza or human influenza viruses,reaching 95.41％-97.49％.The HA and NA segments were de-rived from H3N2 subtype SIV,the NP segment was derived from H1N1 subtype human influenza virus,the M segment was derived from H1N2 subtype SIV,and all other segments were derived from H1N1 subtype SIV.The key receptor sites(190D,223V,226I,228S)of HA protein remained unchanged.The pathogenicity experiment results showed that infected piglets exhibited symptoms such as fever,sneezing,runny nose,the virus could be detoxified to the outside through the nasal cavity,and the lungs had different degrees of lesion.Immunohistochemistry(IHC)showed that the virus could replicate in the lungs.In conclusion,a strain of H3N2 subtype SIV was successfully iso-lated,and the genetic evolution,molecular characteristics and pathogenicity of the virus were stud-ied.It revealed that H3N2 subtype SIV is constantly evolving and had pathogenicity to piglets,pro-viding a reference for monitoring and preventing SIV epidemics in China,and provided a candidate strain for SI vaccine development.

Heart failure is the leading cause of death worldwide. Compound Danshen Dripping Pill (CDDP) or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China. However, the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown. We constructed a new model of heart failure induced by hypercholesterolemia/atherosclerosis in apolipoprotein E (ApoE) and LDL receptor (LDLR) dual deficient (ApoE^-/-LDLR^-/-) mice and investigated the effect of CDDP or CDDP plus a low dose of simvastatin on the heart failure. CDDP or CDDP plus a low dose of simvastatin inhibited heart injury by multiple actions including anti-myocardial dysfunction and anti-fibrosis. Mechanistically, both Wnt and lysine-specific demethylase 4A (KDM4A) pathways were significantly activated in mice with heart injury. Conversely, CDDP or CDDP plus a low dose of simvastatin inhibited Wnt pathway by markedly up-regulating expression of Wnt inhibitors. While the anti-inflammation and anti-oxidative stress by CDDP were achieved by inhibiting KDM4A expression and activity. In addition, CDDP attenuated simvastatin-induced myolysis in skeletal muscle. Taken together, our study suggests that CDDP or CDDP plus a low dose of simvastatin can be an effective therapy to reduce hypercholesterolemia/atherosclerosis-induced heart failure.

Objective:To discuss the effect of remnant cholesterol (RC) levels on carotid intima thickness (CIT) in patients with type 2 diabetes mellitus (T2DM) by ultra-high frequency ultrasound.Methods:A total of 60 patients with T2DM who received treatment in Henan Provincial People′s Hospital from May 2021 to July 2022 were prospectively recruited, and they were divided into a higher RC group (31 cases) and a lower RC group (29 cases) according to the RC levels. Thirty-one age, sex and body mass index(BMI)-matched healthy volunteers were selected as control group. Carotid CIT, carotid media thickness(CMT) and intima-media thickness(CIMT) were measured by 24 MHz ultra-high frequency ultrasound probe. The difference of general clinical data, laboratory indicators and CIMT, CIT, CMT among the three groups were compared, and the influencing factors of CIT in T2DM patients were explored by multivariate regression analysis.Results:①There were no statistical significances in gender, age, BMI, high-density lipoprotein cholesterol (HDL-C) and CMT among the three groups (all P>0.05). There were no statistical significances in duration of diabetes, fasting blood-glucose and glycated haemoglobin between the two subgroups of T2DM (all P>0.05). ②Compared with the control group, CIMT and CIT were thicker in the T2DM group (both P<0.05). ③CIT was thicker in the higher RC group than in the lower RC group ( P<0.05), while the difference of CIMT was not statistically significant the two groups ( P>0.05). ④Multivariate regression analysis showed that RC was the influence factor of CIT in patients with T2DM(β=0.610, P=0.005). Conclusions:CIT is significantly thicker in T2DM patients with higher RC than in those with lower RC, and RC is the influence factor of CIT, which suggests that more attention should be paid to the detection of RC in T2DM patients.

Cell pyroptosis is a programmed death of inflammatory cells. Many members of the gasdermin family （the effector protein family that forms pores） participate in the pathological process of a variety of diseases， such as cancer， myocardial ischemia， renal injury， and osteoarthritis， mainly by activating cysteine aspartate-specific protease （Caspase） for polymerization and shear. Cell pyroptosis has bidirectional regulation. Induction of pyroptosis can promote cell clearance under pathological conditions （such as cancer and tumor cells）， but long-term induction of pyroptosis can lead to abnormal lipid and related vitamin metabolism in vivo. Regulating the balance between cell pyroptosis and proliferation is an important target for traditional Chinese medicine （TCM） treatment of diseases. The Yin-Yang theory runs through the whole process of TCM diagnosis and treatment， which is used to explain the physiological and pathological changes of human body and guide the theory， diagnosis and treatment of diseases and health care. The balance between cell proliferation and pyroptosis is essentially the embodiment of Yin-Yang balance at the cellular level， and the theory of Yin-Yang spontaneous harmonization dominates the balance. TCM intervention on cell pyroptosis is mainly reflected in promoting and inhibiting cell pyroptosis， which has the same significance as Yin-Yang regulation. Based on this theory， this paper revealed the relationship between TCM inhibiting and promoting cell pyroptosis through the Yin-Yang theory， to provide theoretical support for the modernization of the Yin-Yang theory and new goals for the diagnosis and treatment of diseases.

Objective To investigate the risk factors of cognitive dysfunction in patients with traumatic brain injury. Methods From March to September, 2021, 556 hospitalized patients with traumatic brain injury were selected from a multicenter study. A 1∶1 sex-matched case-control study design was used. After assessment by Montreal Cognitive Assessment (MoCA), those with cognitive impairment were as case group and those without cognitive impairment were as control group. They were collected general data and assessed with Social Support Rating Scale (SSRS) and Hospital Anxiety and Depression Scale (HADS). Results Logistic regression analysis showed that college education or above (OR = 0.040) and high level of social support (OR = 0.118) were protective factors for cognitive impairment (P < 0.05). Aged 60 to 88 years (OR = 9.996), severe brain injury (OR = 7.345), headache after injury (OR = 2.159), frequent waking at night or multiple dreams ≥ three times per week (OR = 3.705), severe upper limb dysfunction caused by brain injury (OR = 6.072), depression (OR = 5.202) were risk factors for cognitive impairment (P < 0.05). Conclusion The related factors for cognitive impairment in patients with traumatic brain injury include general factors, disease factors, sleep, psychological and social support and other factors. It is suggested that in addition to the treatment of disease, it is necessary to improve sleep, psychology and social support, to reduce the incidence of cognitive impairment and promote the recovery of disease.

Spearman correlation analysis results showed that ECI, IOS, and EOS were positively correlated with gestational week( rs=0.524, 0.689, 0.609; all P<0.01). HR was negatively correlated with gestational week ( rs=-0.755, P<0.01). The regression equations of ECI, HR, IOS and EOS were Y=0.06X+ 52.214, Y=99.25-1.07X, Y=8.63E-3X+ 0.05, Y=7.94E-3X+ 0.1, respectively. Conclusions:The normal parameters values of E-TVES are summarized.It provides effective support in data for cervical evaluation in the preterm prediction and success of labor induction.

Objective:To explore the changes of left atrial volume and function in patients with early diabetic nephropathy by four-dimensional auto left atrial quantification (4D Auto LAQ).Methods:Forty patients with early diabetic nephropathy (early diabetic nephropathy group), 40 patients with type 2 diabetes (diabetes group) in Henan Provincial People′s Hospital from March 2020 to April 2021 were selected, and 36 healthy volunteers (control group) were collected during the same period. The parameters of conventional echocardiography were measured, and the four-dimensional volume probe was used to obtain the complete left atrial volume image in 5 cardiac cycles. The 4D Auto LAQ software on the EchoPAC workstation was used for analysis to obtain the left atrial volume and strain indicators: left atrial (LA) maximum volume (LAVmax), left atrial minimum volume (LAVmin), pre-systolic volume (LAVpreA), left atrial volume index (LAVImax), left atrial emptying volume (LAEV), left atrial emptying fraction (LAEF), and long axis and circumferential strains in left atrial reserve phase, pipeline phase and systolic phase (LASr, LASr-c; LAScd, LAScd-c; LASct, LASct-c). The differences of these parameters among 3 groups were analyzed.Results:There were no significant differences in interventricular septum end-diastolic thickness(IVSd), left ventricular posterior wall end-diastolic thickness(LVPWd), left ventricular end-diastolic dimension(LVIDd), left ventricular ejection fraction(LVEF), and E/A (ration of early to late diastolic peak flow velocity of mitral orifice) among 3 groups (all P>0.05), and left atrial diameter(LAD), relative wall thickness(RWT), and E/e′ (ration of early diastolic peak flow velocity of mitral orifice to early diastolic velocity of lateral mitral annulus) among 3 groups were significantly different (all P<0.05). Further pairwise comparison results showed that LAD was only significantly different between the early diabetic nephropathy group and control group ( P=0.001 2), and the differences in RWT and E/e′ were statistically significant among 3 groups (all P<0.05). There were no significant differences in LAEV, LAScd-c, and LASct-c among 3 groups (all P>0.05), and LAVmin, LAVmax, LAVpreA, LAVImax, LAEF, LASr, LAScd, LASct, and LASr-c among the 3 groups were significantly different (all P<0.05). The pairwise comparison showed that, compared with the control group and the diabetes group, LAVmin, AVpreA, and LAVImax in the early diabetic nephropathy group were increased, and LAEF, LAScd, LASct, and LASr-c were decreased (all P<0.05). Compared with the control group, LAVmax, LAVImax and LASct in the diabetes group were increased, and LAEF, LAScd, and LASr-c were decreased (all P<0.05). Conclusions:4D Auto LAQ technology can quantitatively evaluate the changes in left atrium volume and function in patients with early diabetic nephropathy. Patients with early diabetic nephropathy have an increase in left atrium volume and a decrease in strain value.
