This paper introduces professor WU Rongzu's clinical experience in using Fuyang Tongmi Decoction （扶阳通秘汤， FTD） to treat irritable bowel syndrome with constipation （IBS-C）. It is believed that yang qi depletion， water cold， earth dampness， and wood constraint are the key pathogenesis.The treatment principle is warming water， drying the earth and venting wood， with the basic formula FTD adjusted according to the symptoms. This approach aims to transport the qi movement of the middle jiao （焦） and support the recovery of intestinal function of directing turbidity downward， providing a treatment strategy for IBS-C caused by yang deficiency.

Objective:To construct an ultrasound-responsive nano-oxygen carrier，and to enhance cell survival within myocardial patches and promote myocardial infarction（MI）repair.Methods:Ultrasound-responsive phase-change nanobubbles（ND）were first prepared and integrated into GelMA hydrogel to construct myocardial patches. Low-intensity pulsed ultrasound（LIPUS）irradiation was applied to explore whether the nanobubbles could optimize the hydrogel properties. Hemoglobin（Hb）was further encapsulated into the nanobubbles to construct an oxygen carrier（ND-Hb）. In vitro and in vivo experiments were conducted to evaluate whether the optimized myocardial patches could improve cell survival and facilitate MI repair. In vitro，cell-loaded patches were divided into 6 groups（control，ND，Hb，LIPUS，LIPUS+ND，and LIPUS+oxygen carrier groups）to assess the cell viability and protein expression. In vivo，an acute MI model was established in SD rats，which were randomly assigned to 4 groups（control，Hb，LIPUS+ND，and LIPUS+oxygen carrier groups）.Myocardial patches were implanted，and cardiac function（echocardiography），cell survival（BLI imaging），angiogenesis（CD31 and α-SMA immunofluorescence）and connexin protein expression（Cx43）were evaluated. Results:Following the incorporation of ND and LIPUS irradiation，scanning electron microscopy revealed numerous micropores（about 2 μm）within the hydrogel were observed by scanning electron microscopy. The nano-oxygen carrier was successfully constructed，with a particle size of（301.2 ± 92.4）nm，and released oxygen under LIPUS stimulation. In vitro，at days 3，7，and 14，the cell survival rates in the LIPUS+oxygen carrier group［（89.6 ± 2.1）%，（79.3 ± 1.8）%，（70.9 ± Conclusions:This study successfully employs LIPUS combined with ND-Hb to enhance hydrogel properties，facilitating nutrient exchange within myocardial patches. Additionally，ultrasound-mediated oxygen release improves seed cell survival and promotes myocardial infarction repair.

The disease spectrum of ABCB4 gene mutation involves various diseases such as progressive familial intrahepatic cholestasis type 3 （PFIC3）， gallstone disease， intrahepatic cholestasis of pregnancy， portal hypertension， liver cirrhosis， and even primary hepatic and biliary malignancies. A young male patient was admitted to Department of Hepatobiliary Medicine， Eastern Hepatobiliary Surgery Hospital， and was initially diagnosed with liver cirrhosis and gallstones， and he was planned to receive laparoscopic cholecystectomy. Preoperative examination showed abnormal liver function， liver cirrhosis， splenomegaly， and mild esophageal varices， and next-generation sequencing was performed to make a confirmed diagnosis of ABCB4 gene mutation-associated liver cirrhosis with gallstones. The liver function of the patient gradually returned to normal after cholagogic treatment with ursodeoxycholic acid capsules.

Objective This study aims to analyze the proteomic characteristics of peripheral blood in patients with lung cancer coexistent with pulmonary tuberculosis(LC-PTB),identify the differential proteins compared with lung cancer(LC)patients,and conduct functional analysis on these proteins.Methods The study included 8 LC-PTB patients and 10 LC patients.The LC patients were newly diagnosed and confirmed by pathology and did not receive any anti-tumor treatment before,while the PTB patients were Mycobacterium tuberculosis positive at the time of sampling.Liquid chromatography-tandem mass spectrometry(LC-MS/MS)was applied to perform proteomic mass spectrometry to assess the differential proteins,and then functional analysis was conducted via bioinformatics.Results A total of 5,185 proteins were detected between two groups.Through differential expression screening,190 proteins(58 upregulated and 132 downregulated)were identified to be differentially expressed.Subcellular localization analysis revealed that the differential proteins were mainly concentrated in the cytoplasm,nucleus,and extracellular matrix.KEGG pathway and GO analysis showed the roles of differential proteins in biological processes including immune response,metabolism,and secretion regulation.Protein interaction network analysis highlighted the importance of SORT1,SAR1B,RPS6KB1,VWF,SHC1,SRPRB,CTSD,TARDBP,RPLP0,PSMA2,RPS6,XPO1,PRKACB,and HLA-DRB1 in LC-PTB.Additionally,the expression changes in proteins like ADA2,MAP3K1,and GLS2 might be closely associated with the development of LC-PTB.Conclusions The proteomic profile comprehensively described the proteomic characteristics of LC-PTB and identified numerous differentially expressed proteins,which could provide further clues for research on biological mechanism of LC-PTB.

Disorders of the gut flora (GF) affect the level of 5-hydroxytryptamine (5-HT) in the brain of patients with generalized anxiety disorder (GAD) and influence the development of the disease. Most of the acupuncture points selected for GAD are based on the principles of local acupuncture points and acupuncture points following the distant channels of the meridians, regarding Baihui (DU 20), Fengchi (GB 20), and Yintang (GV 29) as the main acupuncture points, and the acupuncture points selected for the regulation of GF are Zhongwan (CV 12), Tianshu (ST 25), and Guanyuan (RN 4) and Zusanli (ST 36). Recently, many studies have been conducted on the mechanism of action of acupuncture in the treatment of GAD from the perspective of GF, but few have investigated the theoretical of acupuncture points used to prevent and treat GAD. This paper discusses the theoretical basis of acupuncture to regulate the "microbiota-gut-brain axis" (MGBA) for the prevention and treatment of GAD, and proposes the method of "regulating the internal organs and calming the mind and relieving anxiety" through analyzing the researches on the regulation of GF and GAD.

Objective:To evaluate the prevention effect of low dose pre-irradiation on irradiation-induced lung injury and its possible mechanism.Methods:Totally 320 6-week-old female C57BL/6j mice were divided into control (0 Gy), low-dose (0.5 Gy), high-dose (20 Gy) and low-dose pre-radiation(0.5 Gy+ 20 Gy)groups by the random number method, with 80 mice in each group. The mice in the low-dose and low-dose pre-irradiation groups were placed in the immobilization device under full consciousness and subjected to 0.5 Gy X-ray whole-body irradiation. 2 weeks later, the 0.5 Gy pre-irradiated mice were anesthetized and subjected to 20 Gy X-rays on chest, as the pre-radiation plus high dose radiation group. The mice in the control group were irradiated with mock irradiation (0 Gy). All mice were terminated at designed time points (24 h, 1 month, 3 months and 5 months) after completion of the irradiation schedule, with 20 mice/group at each time point. Then, lung tissues were taken from mice, and pathological changes were observed by hematoxylin-eosin (HE) staining and Masson′s trichrome staining. RT-qPCR and Western blot were used to detect the expressions of mRNAs and proteins of pulmonary fibrosis-related factors.Results:Pathological changes were observed in the lung tissues 1 month after a single high-dose 20 Gy irradiation, mainly including radiation pneumonitis and a small amount of collagen accumulation, which was more serious than low-dose pre-irradiation group, and these pathological changes became more severe when the time after irradiation increased. Meanwhile, the mRNA and protein levels of proSP-C and HOPX in the low-dose pre-irradiation group were higher than those in the high-dose group, except for proSP-C protein expression at 3 and 5 months post-irradiation. A more significant change was that the mRNA level of TGF-β1 in the high-dose group was 5.8-13.6 times higher than that in the other groups at 5 months after irradiation, as well as β-catenin mRNA ( t=4.22, 5.11, P<0.05). At the same time, in the early period (24 h and 1 month) post-irradiation, the level of vimentin protein in the low-dose pre-irradiation group was significantly higher than that in the high-dose group ( t=6.54, 4.28, P<0.05). Conclusions:When the mice were pre-irradiated with 0.5 Gy X-rays, an adaptive protective response was induced in lung tissues, resulting in the tolerance to subsequent high dose irradiation.

Objective:To investigate the effects of type 2 diabetes mellitus (T2DM) on the clinicopathological characteristics and prognosis of patients with hepatocellular carcinoma (HCC) after curative hepatectomy.Methods:From November 2009 to June 2011, the clinicopathological and survival data of HCC patients who underwent radical resection at Eastern Hepatobiliary Surgery Hospital of Naval Medical University were retrospectively analyzed. The patients were divided into T2DM group and non-T2DM group. Clinicopathological characteristics and prognosis of two groups were compared. Chi square test or Fisher exact test were used for statistical analysis. Kaplan-Meier test was used for univariate survival analysis, and Cox proportional hazard regression model was used for multivariate survival analysis.Results:A total of 1 691 patients with HCC were enrolled in this study. Among them, 142 patients (8.4%) were complicated with T2DM. The proportion of patients with onset age≥65 years old, the proportion of men, the proportion of patients with hypertension and γ-glutamyltranspeptidase >61 U/L in the T2DM group were higher than those in non-T2DM group (24.6%, 35/142 vs. 10.4%, 161/1 549; 92.3%, 131/142 vs. 85.7%, 1 327/1 549; 43.7%, 62/142 vs. 12.3%, 191/1 549; 58.5%, 83/142 vs. 49.4%, 765/1 549), while the proportion of patients with chronic hepatitis virus infection and α-fetoprotein >20 μg/L in the T2DM group were both lower than those in non-T2DM group (76.1%, 108/142 vs. 92.0%, 1 425/1 549; 47.2%, 67/142 vs. 59.9%, 928/1 549), and the differences were all statistically significant ( χ2=25.79, 4.75, 100.36, 4.28, 39.01 and 8.66, all P<0.05). The results of univariate survival analysis showed that there was no significant difference in the postoperative overall survival (OS) rate between T2DM group and non-T2DM group ( χ2=3.02, P=0.082). The results of further subgroup analysis showed that among HCC patients with TNM stage Ⅰ, there was statistically significant difference in the OS rate between T2DM group and non-T2DM group ( χ2=4.53, P=0.033). The OS rates at 1 year, 3 years and 5 years after curative resection of HCC patients in T2DM group were lower than those of patients in non-T2DM group (96.0%, 48/50 vs. 97.6%, 558/572; 78.0%, 39/50 vs. 88.6%, 507/572; 68.0%, 34/50 vs. 79.5%, 455/572). The results of multivariate Cox regression survival analysis demonstrated that T2DM was an independent risk factor for postoperative survival in patients with TNM stage Ⅰ HCC (odds ratio=1.663, 95% confidence interval 1.045 to 2.648, P=0.032). Conclusions:The effect of T2DM on prognosis of patients after radical resection of HCC is associated with TNM stage, and its effect may be limited on the early stage of HCC.

Dental resin materials have been widely used in the treatment of dental defects. However, the polymerization shrinkage of the resin materials tends to cause microleakage and accumulation of bacterial plaque, which leads to secondary dental caries. Endowing dental resin with antibacterial properties is an important way to solve this problem. Adding antibacterial agents to dental resin is the main method to give it antibacterial properties. Antimicrobial agents are mainly divided into three types: release type, non-release type and mixed type. In terms of antibacterial effects, the selection and addition of antibacterial agents will affect the antibacterial and mechanical properties of dental resin materials; and the long-term antibacterial effect of antimicrobial agents in the oral cavity remains to be verified; as antimicrobial agents or other environmental factors can lead to drug resistance and even dormant persistent bacteria. In recent years, researchers have been committed to improving the antibacterial effect by modifying antibacterial agents. The sustained release of antimicrobial agents via carriers is also the main research direction. This paper reviews the research progress on the antibacterial properties of dental resin materials.
