Based on the concept of "regulating the five zang organs and harmonizing the spleen and stomach"， globus hystericus is believed to originate from dysfunction of the five zang organs and disharmony of the spleen and stomach. Treatment primarily focuses on regulating the spleen and stomach while also considering other affected organs， with a self-prescribed Anpiwei Jingyan Formula （安脾胃经验方） for harmonizing the spleen and stomach as the foundational treatment. Additionally， syndrome-based modifications are applied according to imbalances in the heart， lung， kidney， or liver. For heart-yang deficiency， modified Linggui Zhugan Decoction （苓桂术甘汤） could be combined； for heart-yin deficiency， modified Tianwang Buxin Pill （天王补心丹） could be combined. For lung failing to disperse and descend and fluid retention， modified Sanao Decoction （三拗汤） could be combined； for lung and stomach yin deficiency， modified Shashen Maidong Decoction （沙参麦冬汤） could be combined. For kidney-yang deficiency with ascending counterflow of cold water， modified Jingui Shensi Pill （金匮肾气丸） could be combined； for kidney-yin deficiency， modified Liuwei Dihuang Pill （六味地黄丸） could be combined. For liver constraint and spleen deficiency， modified Sini Powder （四逆散） could be combined； for liver-yin deficiency or liver stagnation transforming into fire and attacking the stomach， modified Yiguan Decoction （一贯煎） could be combined.

Based on the traditional Chinese medicine theory that "all pain， itching， and sores are related to the heart"， this paper proposes treating recurrent aphthous ulcers from the perspective of the heart. It suggests that excessive heart fire and tissue erosion due to flaming fire in the heart meridian constitute the core pathogenesis of this condition. Hyperactive heart fire is identified as the key pathogenic factor， while heart yin deficiency， obstruction of the heart collaterals， and malnourishment of the heart spirit are considered significant contributing factors. Clinically， the treatment follows the principle of clearing heart fire as the main strategy， supplemented by nourishing yin， activating collaterals， and calming the spirit. The self-formulated Qingxin Yuchuang Formulation （清心愈疮方） serves as the base prescription， with flexible modifications incorporating the Yuyin Formulation （育阴方）， Huoxue Formulation （活血方）， and Yu'an Formulation （郁安方） to address specific syndromes involving heart yin deficiency， collateral blockage， and emotional disturbance.

Objective To explore the action mechanism of Bruton's tyrosine kinase (BTK) inhibitor zanubrutinib on renal fibrosis after renal ischemia-reperfusion injury (RIRI). Methods C57BL/6 mice were randomly divided into sham operation group, modeling group and modeling + zanubrutinib treatment group (zanubrutinib group), with 5 mice in each group. The groups underwent sham operation, RIRI modeling and RIRI modeling + zanubrutinib (5 mg/kg) treatment, respectively. Tissues were collected after 21 days. The morphological changes of the kidneys, histopathological changes, levels of M1 macrophages in the kidneys, inflammatory responses in the kidneys, and the expression of related inflammatory signaling pathways of macrophages induced by lipopolysaccharide(LPS) + interferon(IFN)-γ in vitro after lentivirus transfection were observed. Results Compared with the sham operation group, the kidneys of the modeling group mice shrank, the ratio of unilateral kidney weight to mouse body weight decreased, renal tubular interstitial fibrosis worsened, and the expression of α-smooth muscle actin (α-SMA) and type I collagen in the kidneys increased. The expression of F4/80 and CD86 in the kidneys increased, the lumen of the renal proximal convoluted tubules was significantly dilated, cellular debris accumulated in the lumen and inflammatory cell infiltration occurred, and the messenger RNA (mRNA) levels of CD86, tumor necrosis factor (TNF)-α, interleukin (IL)-6, inducible nitric oxide synthase (iNOS) and IL-1β in the kidneys increased. Compared with the modeling group, the kidneys of the zanubrutinib group mice enlarged after RIRI, the ratio of unilateral kidney weight to mouse body weight increased, renal tubular interstitial fibrosis was alleviated, and the expression of α-SMA and type I collagen in the kidneys decreased. The expression of F4/80 and CD86 in the kidneys decreased, the number of CD45⁺ lymphocytes and CD11b⁺ F4/80⁺ macrophages in the kidneys decreased, the infiltration of CD11b⁺ F4/80⁺ and CD86⁺ macrophages in the damaged tissue decreased, the degree of renal inflammatory pathological changes was milder, and the mRNA levels of CD86, TNF-α, IL-6, iNOS and IL-1β in the kidneys decreased. In vitro experiments using LPS+IFN-γ to induce M1-type macrophages found that the phosphorylation levels of phosphatidylinositol-3-kinase (PI3K), protein kinase B (Akt), and nuclear factor (NF)-κB increased, while the phosphorylation levels decreased after BTK knockdown, indicating that BTK knockdown may inhibit the PI3K/Akt and NF-κB related inflammatory signaling pathways, thereby reducing the pro-inflammatory effects of LPS+IFN-γ induced M1-type macrophages. Conclusions Zanubrutinib may alleviate renal fibrosis after RIRI by inhibiting the PI3K/Akt and NF-κB related inflammatory signaling pathways, reducing the infiltration of M1 macrophages and the expression of related inflammatory factors, providing potential evidence for its clinical application.

Ischemia-reperfusion injury (IRI) is an extremely complicated pathophysiological process, which may occur during the process of myocardial infarction, stroke, organ transplantation and temporary interruption of blood flow during surgery, etc. As key molecules of immune system, macrophages play a vital role in the pathogenesis of IRI. M1 macrophages are pro-inflammatory cells and participate in the elimination of pathogens. M2 macrophages exert anti-inflammatory effect and participate in tissue repair and remodeling and extracellular matrix remodeling. The balance between macrophage phenotypes is of significance for the outcome and treatment of IRI. This article reviewed the role of macrophages in IRI, including the balance between M1/M2 macrophage phenotype, the mechanism of infiltration and recruitment into different ischemic tissues. In addition, the potential therapeutic strategies of targeting macrophages during IRI were also discussed, aiming to provide reference for alleviating IRI and promoting tissue repair.

This article summarized Professor Liu Qiquan's clinical experience in treating urethral syndrome from the perspective of"regulating the five internal organs to calm the spleen and stomach".It is believed that urethral syndrome is located in the urethra,and its core pathogenesis is disharmony between the spleen and stomach,obstruction of dampness,and unfavorable water channel.Therefore,"tranquilizing the spleen and stomach"should be carried out throughout the treatment.At the same time,the occurrence of the disease is closely related to the disorder of the five internal organs.External sensation,internal injury,emotion,diet,fatigue and visceral disorders will affect the function of the five internal organs and then the disease will occur.In clinical practice,based on the idea of"regulating the five internal organs to calm the spleen and stomach",according to the symptoms and manifestations of the patients,the treatment can be guided by comprehensively using the methods of raising the clear and lowering the turbid to harmonize the stomach and dredge the drench,nourishing the heart and clearing the heart to purge heat and dredge the drench,benefiting the lung and purging heat to relieve dampness and dredge the drench,tonifying the kidney and warming the yang to dissipate qi and dredge the drench,dredging the liver and clearing the liver to promote the flow of qi and dredge the drench,which can make the five internal organs harmonious,benefit the waterways.Finally,the symptoms would be reduced and the disease would be cured.

Objective To compare the change features of anti-donor specific antibody (DSA) in different species of sentitized mice after skin transplantation. Methods All mice were divided into the Balb/c → C57BL/6 (6 pairs) and Balb/c → C3H skin transplantation groups (6 pairs). At d0, d2, d4, d7, d13, d17, d28, d35, d42, d49 and d56 after skin transplantation, the serum sample was prepared for detection of DSA-IgG and DSA-IgM levels. Results Moderate increase was noted in the DSA-IgG level in the sensitized mice within 1 week after skin transplantation. The IgG level was significantly increased within 1-4 week and peaked and stabilized within 4-8 week. No significant variation was observed in the DSA-IgM level at 8 weeks after skin transplantation. In the Balb/c → C57BL/6 skin transplantation group, the DSAIgG level was significantly lower than that in the Balb/c → C3H group. Statistical significance was identified in the IgG levels between two groups at d2, d17, d28, d35, d42, d49 and d56 after skin transplantation (all P<0.05). No statistical significance was noted in the DSA-IgM levels between two groups at each time point (all P>0.05). Conclusions Advancing the time of renal transplantation after skin transplantation moderately in the Balb/c → C3H group, or changing to the lower immunoreactive combination of Balb/c → C57BL/6 are aimed to establish AMR mouse models with mild rejection reaction.

Objective To investigate the correlation between red cell volume distribution width (RDW) and the mortality rate of acute respiratory distress syndrome (ARDS) patients after renal transplantation. Methods Clinical data of 106 ARDS patients undergoing renal transplantation were retrospectively analyzed. According to RDW, all patients were assigned into the normal (≤15.0%, n=68) and increasing RDW groups (>15.0%, n=38). Baseline data and the incidence of adverse events were statistically compared between two groups. Kaplan-Meier survival curve was adopted to compare the 50 d-mortality rate between two groups. Cox's proportional hazards regression model was utilized to identify the risk factors of the mortality of ARDS patients. Results Among 106 patients, the 50 d-mortality rate was calculated as 43.4% (46/106). The sequential organ failure assessment (SOFA) score, serum creatinine, hemoglobin and platelet count significantly differed between two groups (all P<0.05). In the increasing RDW group, the 50 d-mortality rate and the incidence of infectious shock were significantly higher than those in the normal RDW group (both P<0.05). Kaplan-Meier survival curve demonstrated that the 50 d-mortality rate significantly differed between two groups (P<0.01). Cox's proportional hazards regression model univariate analysis revealed that hemoglobin level<100 g/L, serum creatinine>133 μmol/L, platelet count<100×109/L, severe ARDS and RDW>15.0% were the potential risk factors of the 50 d-mortality rate in ARDS patients (all P<0.05). Multivariate analysis demonstrated that severe ARDS [odd ratio (OR)=12.77, 95%confidence interval (CI) 11.63-15.39, P<0.001] and RDW>15.0% (OR=2.01, 95%CI 1.02-3.94, P<0.043) were the independent risk factors of the 50 d-mortality rate in ARDS patients. Conclusions RDW elevation is correlated with the severity of disease and 50 d-mortality rate in ARDS patients following renal transplantation. RDW can serve as a clinical parameter to predict the prognosis of ARDS patients after renal transplantation.

Objective To investigate the risk factors of bloodstream infection-related death after liver transplantation.Methods The retrospective case-control study was adopted.The clinical data of the 107 patients with bloodstream infection from 365 liver transplantation patients who were admitted to the Third Xiangya Hospital of Central South University (220 patients) and South Central Hospital Affiliated to Wuhan University (145 patients) from January 1,2002 to December 31,2015 were collected.The patients received modified piggyback liver transplantation.The second or third generation celphalosporin or carbapenems antibiotics were preventively used against infection according to the bacterial culture results before surgery,and the immune inhibitor basic program after surgery was FK506 + prednisone.The observation indicators included:(1) the bloodstream infection status after liver transplantation:incidence of bloodstream infection,frequency of bloodstream infection,inadequate antiinfection treatment,primary infection position,microorganism infection type,bacterial culture results and bloodstream infection-related mortality.(2) The risk factors of blood stream infection-related death after liver transplantation in univariate and multivariate analyses in cluded:the gender,age,resource of donor,usage of immune inhibitor,time between infection and liver transplantation,infection temperature,primary infection position(intraperitoneal or biliary infection),pathogenic microorganism type,nosocomial infection,inadequate antibiotic usage,serum creatinine level,serum albumin (Alb) level,white blood cell (WBC) in peripheral blood,lymphocyte in peripheral blood,platelet (PLT) in peripheral blood and septic shock indexes.The patients were followed up by outpatient examination and telephone interview up to January 31,2016,the follow-up contents included the survival status of the patients,vital signs,using status of immune inhibitor,immune inhibitor concentration,blood routine,biochemical indexes,surgery,other infection-related complications and acute rejection.Continuous variables with normal distribution were represented as ~ ± s.The univariate analysis was done by the Chi-square test.The multivariate analysis was done by the Logistic regression model.Results (1) The bloodstream infection status after liver transplantation:186 bloodstream infections were happened in 107 patients undergoing liver transplantation,with a total incidence of bloodstream infection of 29.32％ (107/365).The incidence of bloodstream infection was 28.18％ (62/220) in the Third Xiangya Hospital of Central South University and 31.03％ (45/145) in the South Central Hospital Affiliated to Wuhan University,with no statistical difference (x2=0.186,P ＞0.05).Of 107 patients,56 patients had once bloodstream infection,31 had twice bloodstream infection and 20 had three times or more bloodstream infection (frequency of the most bloodstream infection was 6).The inadequate anti-infection treatment was applied to the 41.12％ (44/107)of patients with liver transplantation and bloodstream infection.The number of patients with primary infection positions in abdomen,lung,urethra,intravascular catheter and unknown sites were 40,39,3,1 and 24,respectively.The Gram positive bacteria,Gram negative bacteria,fungus and mixed infection of microorganism infection type were detected in 28,24,4 and 51 patients,respectively.There were 102 patients with nosocomial infection.Bacteria culture results in 186 strains of blood sample illustrated:84 strains were Gram positive bacteria as major pathogenic bacteria,among which enterococcus (31 strains) and staphylococcus aureus (23 strains) were dominant strains.The bloodstream infection-related mortality was 37.38％ (40/107),including 35 patients dying of septic shock.(2) The univariate analysis showed that the gender,resource of the donor,infection temperature,type of microorganism,serum creatinine level,serum Alb level,WBC in peripheral blood,PLT in peripheral blood and septic shock were the risk factors affecting bloodstream infection-related death after liver transplantation (x2=5.801,5.920,13.047,12.776,11.366,7.976,25.173,9.289,51.905,P ＜0.05).The multivariate analysis showed that serum Alb level ＜ 30 mg/L and septic shock were the independent risk factors affecting bloodstream infection-related death after liver transplantation (OR =5.839,44.983,95 ％ confidence interval:1.145-29.767,12.606-160.514,P ＜ 0.05).Conclusion It is prone to happen bloodstream infection after liver transplantation,and serum Alb level ＜ 30mg/L and septic shock are the independent risk factors affecting bloodstream infection-related death after liver transplantation.

OBJECTIVE: To evaluate the recovery of patients with end-stage renal disease (ESRD) receiving kidney transplant from cardiac death donors, and to assess graft survival in China from this type of donor. METHODS: A total of 48 cases of patients with ESRD have received the kidneys from cardiac death donors in our hospital between February 2010 and March 2012. We retrospectively analyzed data on the preoperative and postoperative serum creatinine concentrations, on the survival of recipients and allografts with a view to investigating prognoses after this type of kidney transplant. RESULTS: Primary non-function (PNF) did not occur in any of the 48 recipients. Delayed graft function (DGF) occurred in 18 of 48 (37.5%) of kidneys from cardiac death donors, but the occurrence of DGF did not adversely influence patient's survival (P=0.098) or graft survival (P=0.447). Seven of 48 (14.6%) recipients lost their graft. Over a median follow-up period of 8 months (range 0.5-23 months), 39 of 41(95.1%) recipients' graft function had fully recovered. The actuarial graft and patient's survival rates at 1, 3, 6 and 12 months after transplantation were 95.7%, 93.0%, 90.0%, 87.5%, and 100%, 94.9%, 90%, 87.5%, respectively. CONCLUSION As the legislation of donation after brain death (DBD) has not been ratified in China, the use of kidneys from cardiac death donors might be an effective way to increase the number of kidneys available for transplantation here. Our experience indicates good short- and mid-term outcomes with transplants from cardiac death donors.
