ABSTRACT
Objective To investigate the relationship between serum mannan binding lectin(MBL),histi-dine rich glycoprotein(HRG),interleukin(IL)-23/IL-17 inflammatory axis and cerebral vasospasm(CVS)and prognosis in patients with aneurysmal subarachnoid hemorrhage(aSAH)after interventional emboliza-tion.Methods A total of 195 patients with aSAH who underwent interventional embolization treatment in the hospital from March 2019 to February 2022 were selected and were divided into no CVS group(126 cases),mild CVS group(18 cases),moderate CVS group(39 cases),and severe CVS group(12 cases)according to the occurrence and severity of CVS detected by digital subtraction angiography at the 4th postoperative day.The levels of serum MBL,HRG,IL-23 and IL-17 among the four groups before and 3 d after surgery were compared.The patients were followed up for 6 months and divided into good prognosis group(137 cases)and poor prognosis group(58 cases)according to their prognosis.Factors influencing poor prognosis in aSAH pa-tients were analyzed by multivariate Logistic regression model.The predictive value of serum MBL,HRG,IL-23,IL-17 levels and their combined application models for poor prognosis in patients with aSAH was analyzed by receiver operating characteristic(ROC)curve.Results The incidence rate of CVS after interventional em-bolization was 35.38%in 195 patients with aSAH.3 d after surgery,the serum levels of MBL,IL-23 and IL-17 in the mild,moderate,and severe CVS groups were higher than those in the no CVS group,those in the severe CVS group were higher than those in the moderate CVS group,those in the moderate CVS group were higher than those in the mild CVS group(P<0.05).The serum HRG levels in the mild,moderate,and severe CVS groups were lower than those in the non CVS group,those in the severe CVS group were lower than those in the moderate CVS group,those in the moderate CVS group were lower than those in the mild CVS group(P<0.05).3 d after surgery,the levels of serum MBL,IL-23 and IL-17 in the four groups were higher than that before surgery,while the levels of serum HRG were lower than that before surgery(P<0.05).The pro-portions of patients with aneurysm diameter≥6 mm,number of aneurysms>1,surgery time>24 h,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,and serum levels of MBL,IL-23,and IL-17 on the 3rd day after sur-gery in the good prognosis group were lower than those in the poor prognosis group,and serum HRG levels at 3 d after surgery in the good prognosis group were higher than that in the poor prognosis group(P<0.05).Multivariate Logistic regression analysis showed that aneurysm diameter≥6 mm,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,elevated serum levels of MBL,IL-23,and IL-17 and decreased HRG level at 3 d after sur-gery were independent risk factors for poor prognosis in aSAH patients(P<0.05).ROC results showed that serum levels of MBL,HRG,IL-23,and IL-17 at 3 d after surgery had certain predictive power for poor progno-sis in patients with aSAH.The predictive model with the combined application of four indicators had relatively high efficiency(the area under the curve was 0.853).Conclusion Elevated levels of MBL,IL-23,IL-17,and decreased HRG levels in aSAH patients after interventional embolization could increase the risk of CVS and are associated with poor prognosis in aSAH patients after interventional embolization.The above indicators have a certain predictive power for poor prognosis in aSAH patients.

Objective To investigate the expression of cysteine-rich intestinal protein 1(CRIP1),STIP1 ho-mology and U-box protein 1(STUB1)in cancer tissues of patients with hepatocellular carcinoma and their clinical prognostic significance.Methods From February 2018 to February 2020,112 patients with hepatocel-lular carcinoma were selected as the study objects.The expression of CRIP1 and STUB1 in cancer tissues and adjacent tissues of patients with hepatocellular carcinoma was detected by immunohistochemistry.To analyze the relationship between the expression of CRIP1 and STUB1 and their clinicopathological features in hepato-cellular carcinoma patients.Kaplan-Meier survival analysis of the effects of CRIP1 and STUB1 expression on the prognosis of patients with hepatocellular carcinoma.COX regression analysis was performed to analyze the prognostic factors of hepatocellular carcinoma.Results The positive rate of CRIP1 in cancer tissues of pa-tients with hepatocellular carcinoma was 62.50%(70/112),which was significantly higher than that in adja-cent tissues[7.14%(8/112)],the difference was statistically significant(x2=76.652,P<0.05).The positive rate of STUB1 in cancer tissues of patients with hepatocellular carcinoma was 26.23%(32/112),significantly lower than that in adjacent tissues[82.14%(92/112)],and the difference was statistically significant(x2=73.284,P<0.05).The expression of CRIP1 was negatively correlated with STUB1 in cancer tissues(r=-0.678,P<0.001).There were significant differences in the positive rates of CRIP1 and STUB1 in hepato-cellular carcinoma patients with different TNM stages,histological grades and maximum tumor diameter(P<0.05).The 3-year cumulative survival rate of CRIP1 positive group was significantly lower than that of CRIP1 negative group,with statistical significance(Log-rank x2=29.601,P<0.001).The 3-year cumulative survival rate of STUB1 negative group was significantly lower than that of STUB1 positive group,with statistical sig-nificance(Log-rank x2=13.590,P<0.001).TNM stage Ⅱ-Ⅲ,histological grade Ⅲ,maximum tumor diam-eter>5 cm,CRIP1 positive and STUB1 negative were independent risk factors for prognosis of hepatocellular carcinoma patients.Conclusion CRIP1 expression is up-regulated and STUB1 expression is down-regulated in hepatocellular carcinoma tissues.The prognosis of patients with hepatocellular carcinoma can be evaluated clinically based on the expression of CRIP1 and STUB1 in hepatocellular carcinoma tissues.
ABSTRACT
Objective To study the construction of risk prediction model for postoperative recurrence of ad-vanced epithelial ovarian cancer based on serum human epididymis protein 4(HE4),platelet count/lymphocyte count ratio(PLR),relaxin(RLX),karyopherin α2(KPNA2).Methods 124 patients with advanced epithelial o-varian cancer diagnosed and treated in Suzhou Municipal Hospital(East District)from January 2016 to January 2019 were selected as the study objects,patients with advanced epithelial ovarian cancer were divided into re-currence group and the non-recurrence group based on whether they had recurred or not.The level of HE4 was detected by electrochemical luminescence immunoassay,PLR was calculated according to the blood routine re-sults,and RLX and KPNA2 levels were detected by enzyme-related immunosorbent assay.Multivariate Logis-tic regression analysis was used to analyze the influencing factors of postoperative recurrence in patients with advanced epithelial ovarian cancer,and establish a risk prediction model for postoperative recurrence of ad-vanced epithelial ovarian cancer.Receiver operating characteristic(ROC)curve was used to evaluate the pre-dictive efficacy of the model for postoperative recurrence of advanced epithelial ovarian cancer,and Hosmer-Lemeshow test was used to analyze the fitting of recurrence risk prediction model for patients with advanced epithelial ovarian cancer.Results There was a statistically significant difference in International Federation of Gynecology and Obstetrics(FIGO)staging and serum levels of carbohydrate antigen 125,HE4,PLR,RLX and KPNA2 between the recurrence group and the non-recurrence group(P<0.05).FIGO staging Ⅳ of cancer and elevated serum HE4,PLR,RLX and KPNA2 were risk factors for postoperative recurrence in patients with advanced epithelial ovarian cancer(P<0.05).ROC curve analysis showed that,the area under the curve of the recurrence risk prediction model for postoperative recurrence risk of advanced epithelial ovarian cancer was 0.859,which was significantly higher than that single indicator detected by HE4,PLR,RLX and KP-NA2.Hosmer-Lemeshow test showed that the recurrence risk prediction model of advanced epithelial ovarian cancer had a good fitting(x2=7.869,P=0.437).Conclusion The risk prediction model for postoperative re-currence of advanced epithelial ovarian cancer based on serum HE4,PLR,RLX,KPNA2 and FIGO staging of cancer has high predictive value for evaluating postoperative recurrence of advanced epithelial ovarian cancer,and deserves clinical attention.
ABSTRACT
Objective To investigate the predictive value of serum soluble tumor necrosis factor-like weak inducer of apoptosis(sTWEAK)and Netrin-1 combined with acute physiology and chronic health evaluationⅡ(APACHE Ⅱ)score for poor prognosis in patients with severe craniocerebral injury after surgery.Methods Totally 120 patients with severe craniocerebral injury admitted to a hospital from June 2020 to June 2022 were divided into good prognosis group and poor prognosis group according to the prognosis 30 days af-ter surgery.The serum levels of sTWEAK,Netrin-1 and APACHE Ⅱ score were compared between the two groups.Univariate and multivariate Logistic regression were used to analyze the influencing factors of poor prognosis in patients with severe craniocerebral injury,and the prediction model of serum sTWEAK,Netrin-1 and APACHE Ⅱ score combined was constructed.The predictive value of serum sTWEAK,Netrin-1 level and APACHE Ⅱ score in patients with severe craniocerebral injury after surgery was analyzed by receiver operat-ing characteristic(ROC)curve.Results The duration of intensive care unit stay in the poor prognosis group was longer than that in the good prognosis group,and the albumin level,Glasgow Coma scale and serum Ne-trin-1 level at admission were lower than those in the good prognosis group.The proportion of multiple brain contusion and laceration,the proportion of mechanical ventilation,APACHE Ⅱ score at admission and the lev-els of serum sTWEAK,blood creatinine and blood urea nitrogen were higher than those in the group with good prognosis,and the differences were statistically significant(P<0.05).Multivariate Logistic regression analysis showed that multiple brain contusion and laceration,decreased Netrin-1 level,increased APACHE Ⅱscore and increased sTWEAK level at admission were risk factors for poor prognosis in patients with severe craniocerebral injury(P<0.05).ROC curve analysis showed that the area under the curve and 95%CI of ser-um sTWEAK,Netrin-1 and APACHE Ⅱ scores were 0.742(0.552-0.925),0.731(0.488-0.963),0.714(0.502-0.911)and 0.882(0.795-0.947)respectively when the three indexes were used alone and in com-bination.Conclusion Serum sTWEAK and Netrin-1 combined with APACHE Ⅱ score have good predictive value for the poor prognosis of patients with severe craniocerebral injury after surgery,and can provide refer-ence for the formulation of clinical treatment.
ABSTRACT
Recent progress in targeted metabolic therapy of cancer has been limited by the considerable toxicity associated with such drugs. To address this challenge, we developed a smart theranostic prodrug system that combines a fluorophore and an anticancer drug, specifically 6-diazo-5-oxo-l-norleucine (DON), using a thioketal linkage (TK). This system enables imaging, chemotherapy, photodynamic therapy, and on-demand drug release upon radiation exposure. The optimized prodrug, DON-TK-BM3, incorporating cyanine dyes as the fluorophore, displayed potent reactive oxygen species release and efficient tumor cell killing. Unlike the parent drug DON, DON-TK-BM3 exhibited no toxicity toward normal cells. Moreover, DON-TK-BM3 demonstrated high tumor accumulation and reduced side effects, including gastrointestinal toxicity, in mice. This study provides a practical strategy for designing prodrugs of metabolic inhibitors with significant toxicity stemming from their lack of tissue selectivity.
ABSTRACT
BACKGROUND@#Primary dysmenorrhea (PD) is the most common complaint associated with menstruation and affects up to three-quarters of women at some stage of their reproductive life. In Chinese medicine, navel therapy, treatment provided at Shenque (CV 8), is used as a treatment option for PD.@*OBJECTIVE@#To evaluate the effect of navel therapy on pain relief and quality of life in women with PD, compared with Western medicine (WM).@*METHODS@#China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), SinoMed and Wanfang Database, MEDLINE, the Cochrane Library, Embase, Web of Science, and the International Clinical Trial Registry of the U.S. National Institutes of Health were searched from their inceptions to April 1, 2021. Randomized controlled trials (RCTs) assessing therapeutic effects of navel therapy on PD were eligible for inclusion. RevMan 5.4 software was used for data analyses. The certainty of the evidence was assessed using the online GRADEpro tool.@*RESULTS@#Totally 24 RCTs involving 2,614 participants were identified. Interventions applied to acupuncture point CV 8 included: herbal patching, moxibustion or combined navel therapy (using at least 2 types of stimulation). Compared to placebo, there was a significant effect in favor of navel therapy on reducing overall menstrual symptom scores at the end of treatment [mean difference: -0.82, 95% confidence interval (CI): -1.00 to -0.64, n=90; 1 RCT]. As compared with Western medicine, navel therapy had a superior effect on pain intensity as assessed by Visual Analogue Scale at the end of treatment [standardized mean difference (SMD): -0.64, 95% CI: -1.22 to -0.06, I2=80%, n=262; 3 RCTs]; on symptom resolution rate at 3-month follow-up (risk ratio: 1.94, 95% CI: 1.47 to 2.56, n=1527, I2=38%; 13 RCTs); and on global menstrual symptoms score at the end of treatment (SMD: -0.67, 95% CI: -0.90 to -0.45, I2=63%, n=990; 12 RCTs). Subgroup analyses showed either a better or an equivalent effect comparing navel therapy with Western medicine. No major adverse events were reported. The methodological quality of included trials was poor overall.@*CONCLUSIONS@#Navel therapy appears to be more effective than Western medicine in decreasing menstrual pain and improving overall symptoms of PD. However, these findings need to be confirmed by well-designed clinical trials with adequate sample size (Systematic review registration at PROSPERO, No. CRD42021240350).

As a non-invasive, objective, dynamic and continuous assessment method, the cardiopulmonary exercise testing can effectively evaluate patients′ cardiopulmonary function, exercise potential, risk stratification, prognosis, thus guiding the treatment decisions.In recent years, cardiopulmonary exercise testing has been widely used in multiple disciplines and fields, but the testing requires a high level of theoretical knowledge and operational skills of professionals.In addition, the cardiopulmonary exercise testing has been well documented in adults with cardiovascular disease, but little research has been done for cardiopulmonary exercise testing in children with cardiovascular disease.This article reviews the role of cardiopulmonary exercise testing in the evaluation of congenital heart disease, Kawasaki disease, pulmonary hypertension, and hypertension in children to provide a basis for better application of cardiopulmonary exercise testing in pediatric clinical work.
ABSTRACT
Traditional Chinese Medicine (TCM) non-drug therapy for gastroesophageal reflux mainly includes appropriate TCM techniques, such as conventional acupuncture, moxibustion, fire needle, etc. Emotional therapy, such as regulating emotion, transforming the patient's spirit and change the state of qi, the five-element music therapy, etc; exercise therapy, such as Baduanjin and Zhanzhuang, can be used alone, or in combination, or in combination with oral administration of Chinese materia medica. By reducing the probability of esophageal sphincter relaxation, inhibiting gastric acid secretion, improving esophageal motility disorder, reducing visceral hypersensitivity, immune regulation and other effects, it can alleviate the symptoms of acid reflux, heartburn and pharyngeal discomfort, and help to improve the patients' anxiety, depression and other negative emotions. It has the characteristics of simplicity and fewer adverse reactions, at the same time, according to the patient's condition and compliance to choose the appropriate therapy. The mechanism of TCM non-drug therapy in the treatment of this disease needs to be further explored, so as to better guide clinical popularization and application.
ABSTRACT
OBJECTIVE@#To observe the clinical efficacy of lidong needling therapy (acupuncture technique combined with therapeutic movement of the body) on upper limb lymphedema after breast cancer surgery in combination with functional exercise.@*METHODS@#A total of 73 patients with postoperative lymphedema of breast cancer in the upper limbs were randomized into an observation group (36 cases) and a control group (37 cases). The routine nursing care and functional exercise were given in the control group, twice a day, for about 10-15 min each time, lasting 8 weeks. On the basis of the treatment as the control group, lidong needling therapy was applied to the acupionts on the affected upper limb, i.e. Jianyu (LI 15), Waiguan (TE 5), Hegu (LI 4) and ashi points (the most obvious swelling sites), as well as to bilateral Yinlingquan (SP 9) and Zusanli (ST 36), etc. The needles were retained for 30 min. While the needles retained, the patients were asked to move the affected shoulder to 90° by the sagittal anteflexion and keep it elevated. Simultaneously, the hand on the affected side was clenched and opened slowly and coordinately. Lidong needling therapy was delivered once every two days, three times weekly for 8 weeks. Before and after treatment, the difference of the circumference between the affected and healthy limbs, the score of visual analogue scale (VAS) for swelling and the score of disability of arm, shoulder and hand (DASH) were compared in the patients of the two groups. The clinical efficacy was evaluated.@*RESULTS@#After 2, 4, 6 and 8 weeks of treatment, except for the circumference of the area 10 cm below the cubitel crease in the control group, the differences in the circumferences of the rest parts between the affected and healthy limbs were reduced in comparison with those before treatment in the two groups (P<0.01, P<0.05). After 6 weeks of treatment, in the observation group, for the circumference at the level of hand between the thumb and the index finger and that of the wrist, the differences between the affected and healthy limbs was smaller compared with those in the control group (P<0.05). After 8 weeks of treatment, except for the areas 5 cm below and above the cubitel crease, the differences of circumferences between the affected and healthy limbs in the observation group were smaller than those in the control group in the rest parts (P<0.01, P<0.05). After 8 weeks of treatment, the swelling VAS scores were reduced when compared with those before treatment in the two groups (P<0.05), and the score in the observation group was lower than that in the control group (P<0.01). After 4 and 8 weeks of treatment, DASH scores were reduced in comparison with those before treatment in the two groups (P<0.01). The total effective rate of the observation group was 83.3% (30/36), which was higher than that of the control group (35.1%, 13/37, P<0.01).@*CONCLUSION@#Lidong needling therapy combined with the functional exercise obtains the satisfactory clinical effect on the upper limb lymphedema after breast cancer surgery. This treatment effectively relieves swelling and improves the upper limb function.

Objective:To determine classification and clinical features of morphea.Methods:A retrospective analysis was conducted on epidemiological information about clinical manifestations of and laboratory data from 180 patients with morphea, who visited Zhongshan Hospital, Fudan University from January 2010 to July 2021. Two-independent-sample t test was used to compare the age at onset between genders, and chi-square test to analyze differences in clinical characteristics between different genders and subtypes. Results:Among the 180 patients, 123 were females and 57 were males, with a male-to-female ratio of 1∶2.16. The age at onset of morphea was 28.69 ± 17.97 years for female patients, and 29.90 ± 20.67 years for male patients. Among them, linear morphea was the most common type in this study (68 cases, 37.78%), followed by plaque morphea (63 cases, 35.00%), mixed morphea (28 cases, 15.56%) and deep morphea (21 cases, 11.67%). The disease occurred in all age groups, but the age at onset significantly varied among different clinical subtypes ( F = 5.95, P < 0.001). No significant difference was observed in the age at onset or proportion of clinical subtypes between genders ( F = 0.15, P = 0.696; χ2 =2.88, P = 0.410). Atrophoderma of Pasini and Pierini (APP) was very common (62 cases, 34.44%) in the 180 patients, which mainly manifested as plaques or linear lesions, and 26 out of 45 patients with plaque APP and 11 out of 17 with linear APP were both accompanied by other subtypes of morphea. Among the 75 patients tested for autoantibody profiles, 34 (45.33%) presented with positive results. More diverse types of autoantibodies were found in female patients compared with male patients, and antinuclear antibodies, anti-SSA and anti-SSB antibodies were the most common types. There were various types of comorbidities in female patients, but lichen sclerosus et atrophicus and vitiligo were the most common comorbidities in both genders. Conclusion:High incidence and frequent co-occurrence with other subtypes of APP may be the characteristics of Chinese patients with morphea, and it is recommended to classify morphea into plaque, linear, deep and mixed subtypes.
ABSTRACT
Research progress in the establishment of long-term control goals and treat-to-target in the treatment of atopic dermatitis (AD) was searched and summarized in this review. The TREatment of ATopic eczema (TREAT) Registry Taskforce defined a minimum follow-up frequency of initially 4 weeks after commencing treatment, then every 3 months while on treatment and every 6 months while off treatment; the international Harmonising Outcome Measures for Eczema (HOME) group recommended that the long-term control of AD should be measured by either the Recap of Atopic Eczema (RECAP) instrument or the Atopic Dermatitis Control Tool (ADCT) . In order to achieve the treat-to-target in AD, a panel comprising 87 participants from 28 countries developed and published "Treat-to-target in atopic dermatitis: an international consensus on a set of core decision points for systemic therapies" in early 2021, which recommended 3 months and 6 months as two evaluation time points, and various disease outcome domains spanning symptoms, signs, quality of life plus patient global assessment as the target. By setting the time-specific outcome thresholds, the consensus provided a framework for shared decision-making on systemic treatment adjustment for AD patients. This review summarizes concepts and indicators related to the assessment of long-term control of and treat-to-target in AD, in the hope of providing some ideas for clinical management, especially the long-term control, of AD in China.
ABSTRACT
OBJECTIVE@#To investigate the therapeutic effect of Epothilone D on traumatic optic neuropathy (TON) in rats.@*METHODS@#Forty-two SD rats were randomized to receive intraperitoneal injection of 1.0 mg/kg Epothilone D or DMSO (control) every 3 days until day 28, and rat models of TON were established on the second day after the first administration. On days 3, 7, and 28, examination of flash visual evoked potentials (FVEP), immunofluorescence staining and Western blotting were performed to examine the visual pathway features, number of retinal ganglion cells (RGCs), GAP43 expression level in damaged axons, and changes of Tau and pTau-396/404 in the retina and optic nerve.@*RESULTS@#In Epothilone D treatment group, RGC loss rate was significantly decreased by 19.12% (P=0.032) on day 3 and by 22.67% (P=0.042) on day 28 as compared with the rats in the control group, but FVEP examination failed to show physiological improvement in the visual pathway on day 28 in terms of the relative latency of N2 wave (P=0.236) and relative amplitude attenuation of P2-N2 wave (P=0.441). The total Tau content in the retina of the treatment group was significantly increased compared with that in the control group on day 3 (P < 0.001), showing a consistent change with ptau-396/404 level. In the optic nerve axons, the total Tau level in the treatment group was significantly lower than that in the control group on day 7 (P=0.002), but the changes of the total Tau and pTau-396/404 level did not show an obvious correlation. Epothilone D induced persistent expression of GAP43 in the damaged axons, detectable even on day 28 of the experiment.@*CONCLUSION@#Epothilone D treatment can protect against TON in rats by promoting the survival of injured RGCs, enhancing Tau content in the surviving RGCs, reducing Tau accumulation in injured axons, and stimulating sustained regeneration of axons.

ObjectiveTo explore the regulatory effect of Gouqi chewable tablets on innate and adaptive immunity in normal mice and its antioxidant activity in vitro and in vivo. MethodThe effects of low-, medium-, and high-dose groups (0.25, 0.5, 1.5 g·kg-1) on the immune function of normal mice were observed by carbon clearance test, immune organ index test, serum hemolysin test, ConA-induced splenic lymphocyte proliferation test, and natural killer cell (NK cell) activity test. The effects of Gouqi chewable tablets on the antioxidant capacity in vivo were determined by detecting the content of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) in mice serum. The in vitro antioxidant activity of Gouqi chewable tablets was detected by 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and hydroxyl radical scavenging tests. ResultCompared with the blank control group, the low-, medium-, and high-dose groups of Gouqi chewable tablets improved the viability of NK cells, the proliferation of splenic lymphocytes, and the level of serum hemolysin antibody in mice (P<0.05). The high-dose group increased the thymus index, spleen index, and phagocytic function of macrophages (P<0.05, P<0.01). As compared with the blank control group, the activity of GSH-Px in mice serum in the medium-dose group was increased (P<0.05), and the content of MDA in mice serum in the high-dose group was decreased (P<0.05). In in vitro antioxidant tests, the median inhibitory concentration (IC50) values of Gouqi chewable tablets were 1.64±0.20, 2.04±0.03, and 10.27±0.03 g·L-1 by the DPPH, ABTS, and OH- free radical method, respectively. Those results indicated that Gouqi chewable tablets have good antioxidant effects in vitro. ConclusionGouqi chewable tablets can enhance the immune function of mice with good antioxidant effects.
ABSTRACT
Histone acetylation is one of the epigenetic modifications. Histone acetylation, which is catalyzed by histone acetyltransferases and negatively regulated by histone deacetylases, plays an important role in a variety of cellular physiological and pathophysiological processes. Recent studies have shown that histone deacetylases are involved in a variety of pathophysiological responses to acute kidney injury, such as apoptosis, dedifferentiation, proliferation and regeneration. This article reviews the role and underlying mechanism of histone deacetylases in acute kidney injury induced by ischemia reperfusion, nephrotoxicants, sepsis and rhabdomyolysis.

Signaling pathways in innate and adaptive immunity play vital roles in pathogen recognition and the functions of immune cells. Higher-order assemblies have recently emerged as a central principle that governs immune signaling and, by extension, cellular communication in general. There are mainly two types of higher-order assemblies: 1) ordered, solid-like large supramolecular complexes formed by stable and rigid protein-protein interactions, and 2) liquid-like phase-separated condensates formed by weaker and more dynamic intermolecular interactions. This review covers key examples of both types of higher-order assemblies in major immune pathways. By placing emphasis on the molecular structures of the examples provided, we discuss how their structural organization enables elegant mechanisms of signaling regulation.
ABSTRACT
OBJECTIVE: To analyze the diagnosis of occupational disease and the detection status of suspected occupational disease and occupational contraindication in recent years in a petrochemical enterprise. METHODS: The data of new cases of occupational disease reported by a petrochemical enterprise from 2008 to 2019, the cases of suspected occupational disease and occupational contraindication from 2015 to 2019 were collected. The related data was descriptively analyzed. RESULTS: A total of 30 new cases of occupational disease were reported in this petrochemical enterprise from 2008 to 2019. Among them, there were 16 cases of occupational noise deafness, 10 cases of chronic occupational benzene poisoning, 2 cases of occupational leukemia caused by benzene, 1 case of occupational solvent gasoline poisoning and 1 case of occupational pneumoconiosis. Among the 30 cases of occupational diseases, 28 cases(93.3%) were related to benzene and noise exposure, and 19 cases(63.3%) came from the chemical and oil refining divisions. From 2015 to 2019 in this petrochemical enterprise, 24 cases of suspected occupational disease were reported, of which 17(70.8%) suspected cases were diagnosed as occupational disease, and 63 cases of occupational contraindication were reported, including 47(74.6%) cases of occupational contraindication caused by noise. CONCLUSION: Benzene and noise should be taken as the key factors of occupational hazard for prevention and control in the petrochemical enterprises, and control measures should be adopted for special operation links and job posts to control the hidden dangers of benzene and noise that exceeds the standard limits.
ABSTRACT
Tuberculosis (TB) is an infectious fatal disease that seriously endangers human health worldwide.Isoniazid (INH) is an important first-line drug for TB, but it can cause serious adverse drug reactions, such as liver injury and even liver failure.At present, it is believed that metabolites of INH, imbalance of oxidative stress responses and immune response disorders are major causes of INH induced liver injury.In addition, involved genes and gene polymorphisms are susceptible to liver injury caused by INH.In this paper, the association of INH induced liver injury with the polymorphisms of genes related to INH metabolizing enzymes, as well as oxidative stress and immune responses are summarized to improve the understanding of INH induced liver injury and provide novel directions for its prevention and treatment.

ABSTRACT
Objective:To analyze the clinical features of absolute incidental prostate cancer (AIPCa) and pseudo-incidental prostate cancer (PIPCa).Methods:Between January 2013 and October 2019, 52 male patients who were diagnosed as incidental prostate cancer (IPCa) with their postoperative pathological examination in our center were included. None of them had any evidence of prostate cancer before. Their median age was 77.5(ranging 55-93) years old. 48 cases underwent PSA examination. The median tPSA was 6.7 (ranging 1-46) ng/ml, except 1 case tPAS>100ng/ml. The median IPSS score was 27.7(ranging 12-35). 48 cases accepted prostatic ultrasound examination. The median prostate volume was 38.6 (ranging 2.3-130.2)ml. Among them, 13 patients underwent transurethral resection of the prostate (TURP), 24 patients underwent transurethral enucleation and resection of the prostate(TUERP), 15 patients underwent radical cystoprostatectomy(RCP). According to the patients′ preoperative examination, AIPCa and PIPCa were redefined. Clinical characteristics, postoperative pathology and follow-up of the two groups were compared and analyzed.Results:There was no significant difference in age, IPSS score, tPSA, T stage and Gleason score between the operation methods groups except for prostate volume and resection ration of prostate ( P>0.05). Among those group, the sequence of prostatic resection ration was RCP>TUERP>TURP( P<0.001). There was no significant difference in age, IPSS score, prostate volume, proportion of T 1b and Gleason score between AIPCa and PIPCa groups. However, the analysis showed higher tPSA(14.68 ng/ml vs. 3.14 ng/ml) in PIPCa ( P<0.001). With a mean follow-up of 33 months(ranging 6-78 months), 23.8%(5/21) patients in AIPCa group and 45.2%(14/31) patients in PIPCa group were found to have increased PSA and underwent radical prostatectomy or androgen deprivation therapy in the follow-up. There was no metastasis or death in AIPCa group, while 2 patients had bone metastasis and 1 patient died of prostate cancer in PIPCa group. Conclusions:According to the indication of prostate biopsy, PIPCa and AIPCa were defined. PIPCa has a relatively poor prognosis, some of them may be missed diagnosis and clinical underestimation. In order to avoid missed diagnosis before operation, we should strictly define IPCa and follow the indications of biopsy, emphasize the reference value of PSA in tumor screening and biopsy, and careful handle the negative results of biopsy when PSA is abnormal.
ABSTRACT
Objective To establish the UPLC fingerprints of Zhidong Granules (ZG) and determine the content of three constituents. Methods With baicalin as a reference peak, the UPLC fingerprints of 11 batches of samples were established. The analysis of ZG was performed on a 40 ℃ thermostatic Acquity HSS T3 column (150 mm × 2.1 mm, 1.8 μm), with the mobile phase comprising of acetonitrile-0.1% formic acid flowing at 0.3 mL/min in a gradient elution manner, and the detection wavelength was set at 254 nm. Results The UPLC fingerprint was established and 16 components were identified (gallic acid, asperuloside, methyl deacetylcyrrhizin, chlorogenic acid, genipin 1-gentiobioside, geniposide, paeoniflorin, chrysin-6-C-β-D-glucopyranosyl-8-C-α-L- arabinopyranoside, chrysin-6-C-α-L-arabopylanose-8-C-β-D-glucoside or isomer, baicalin, baicalin isomer, oroxylin A-7-O- glucuronide, wogonoside, wogonin, and schizandrin). The similarity of 11 batches of preparations were at least 0.98. Baicalin, paeoniflorin, and geniposide showed good linear relationships within the ranges of 12.15-388.80 μg/mL, 6.52-209.00 μg/mL, and 8.38-268.00 μg/mL, whose average recoveries (RSD) were 100.98% (3.04%), 100.49% (0.60%), and 100.55% (2.73%), respectively. The content of baicalin in the 11 batches of preparations was between 7.46 and 12.40 mg/g, the content of geniposide was between 7.01 and 13.27 mg/g, and the content of paeoniflorin was between 7.68 and 12.76 mg/g. Conclusion The method is accurate, simple, stable, and reliable, and can be used for quality control of ZG.
