Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

OBJECTIVE: To investigate the clinicopathological features and differential diagnosis of male genital system lymphoma (MGSL). METHODS: We retrospectively analyzed the clinicopathological and immunophenotypic features and prognosis of 80 cases of MGSL. RESULTS: The onset age of the MGSL patients ranged from 4 to 85 (median 62) years old. All the cases showed non-specificity of the imaging features and clinical manifestations. MGSL was located mainly in the testis (n = 66), followed by the prostate (n = 7), epididymis (n = 3), scrotum (n = 3) and penile glans (n = 1). Diffused large B cell lymphoma (DLBCL) was the most common pathological type (n = 62), next came extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) (n = 7) and other rare types (n = 12). During the 1－112-month follow-up of 10 of the 19 patients, 1 died at 1 month after diagnosed with prostatic B-lymphoblastic lymphoma (B-LBL) and another 1 died at 50 months after diagnosed with testicular DLBCL. CONCLUSION MGSL is rare clinically, mainly of the DLBCL type pathologically, lacking specificity in clinical symptoms and imaging manifestation. The definite diagnosis of the malignancy depends on histopathology combined with related molecular examination and immunohistochemical labeling, and R-CHOP chemotherapy is the first choice for its treatment.

OBJECTIVE: To construct and validate a prognostic prediction model for children with sepsis using the Phoenix sepsis score (PSS). METHODS: A retrospective case series study was conducted to collect clinical data of children with sepsis admitted to the pediatric intensive care unit (PICU) of the Affiliated Hospital of Guizhou Medical University from January 2022 to April 2024. The data included general information, the worst values of laboratory indicators within the first 24 hours of PICU admission, PSS score, pediatric critical illness score (PCIS), and the survival status of the children within 30 days of admission. The statistically significant indicators in univariate Logistic regression analysis were included in multivariate Logistic regression analysis to screen the risk factors affecting the prognosis of children with sepsis and construct a nomogram model. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive performance of the model. The Bootstrap method was used to perform 1 000 repeated sampling internal verification and draw the calibration curve of the model. RESULTS: A total of 199 children with sepsis were included, of which 32 died and 167 survived 30 days after admission. In the univariate Logistic regression analysis, shock, white blood cell count (WBC), international normalized ratio (INR), lactic acid (Lac), PSS score, and PCIS score were identified as statistically significant predictors. These variables were then included in the multivariate Logistic regression analysis, which demonstrated that shock [odds ratio (OR) = 4.258, 95% confidence interval (95%CI) was 1.049-17.288], WBC (OR = 1.124, 95%CI was 1.052-1.210), and PSS score (OR = 1.977, 95%CI was 1.298-3.012) were independent risk factors for mortality in pediatric patients with sepsis (all P < 0.05). A nomogram model was constructed based on these three risk factors, with the model equation as follows: -4.809+1.449×shock+0.682×PSS score+0.117×WBC. The calibration curve results showed that the model's predictions were highly consistent with the actual observations. The ROC curve showed that when the Youden index of the prediction model was 0.792, the sensitivity and specificity were 90.6% and 88.6%, respectively, and the area under the curve (AUC) was 0.957 (95%CI was 0.930-0.984), which was higher than the AUC of shock, WBC, and PSS score alone (0.808, 0.667, 0.908, respectively). CONCLUSIONS Shock, WBC, and PSS score have demonstrated certain predictive value for mortality in children with sepsis. The nomogram model based on the above indicators has important clinical significance for evaluating the prognosis and guiding treatment of children with sepsis.

OBJECTIVE: Cigarette smoking exacerbates the progression of pulmonary tuberculosis (TB). The role of tertiary lymphoid structures (TLS) in chronic lung diseases has gained attention; however, it remains unclear whether smoking-exacerbated lung damage in TB is associated with TLS. This study aimed to analyze the characteristics of pulmonary TLS in smokers with TB and to explore the possible role of TLS in smoking-related lung injury in TB. METHODS: Lung tissues from 36 male patients (18 smokers and 18 non-smokers) who underwent surgical resection for pulmonary TB were included in this study. Pathological and immunohistological analyses were conducted to evaluate the quantity of TLS, and chest computed tomography (CT) was used to assess the severity of lung lesions. The correlation between the TLS quantity and TB lesion severity scores was analyzed. The immune cells and chemokines involved in TLS formation were also evaluated and compared between smokers and non-smokers. RESULTS: Smoker patients with TB had significantly higher TLS than non-smokers ( P < 0.001). The TLS quantity in both the lung parenchyma and peribronchial regions correlated with TB lesion severity on chest CT (parenchyma: r = 0.5767; peribronchial: r = 0.7373; both P < 0.001). Immunohistochemical analysis showed increased B cells, T cells, and C-X-C motif chemokine ligand 13 (CXCL13) expression in smoker patients with TB ( P < 0.001). CONCLUSION Smoker TB patients exhibited increased pulmonary TLS, which was associated with exacerbated lung lesions on chest CT, suggesting that cigarette smoking may exacerbate lung damage by promoting TLS formation.

Yellowish sweating disease is one of the fluid-retention diseases recorded in Jin Gui Yao Lve(Synopsis of the Golden Cabinet).The symptoms of yellowish sweating disease are complex,involving multiple visceral lesions,which are caused by interior heat and exterior deficiency,together with the concurrent invasion of pathogens of wind and water.Huangqi Shaoyao Guizhi Kujiu Decoction(mainly composed of Astragali Radix,Paeoniae Radix Alba,Cinnamomi Ramulus and vinegar)and Guizhi Plus Huangqi Decoction(mainly composed of Cinnamomi Ramulus and Astragali Radix)are the classical formula for the treatment of yellowish sweating disease.Both of the formulas have the actions of warming defensive qi and dredging yang,removing fluid retention and resolving dampness.Usually suffering heat in the spleen and stomach,together with carelessness in daily living and wind-water pathogens attacking the exterior,contributes to the key pathogenesis of diabetes mellitus.The clinical manifestations,etiology,occurrence and progression,and prognosis of yellowish sweating disease are similar to those of diabetic complications.Therefore,the treatment of diabetes complications such as diabetic kidney disease,diabetic cardiomyopathy,diabetic peripheral neuropathy,diabetes mellitus complicated with liver dysfunction,diabetic foot,and diabetic retinopathy can follow the therapeutic principles of yellowish sweating disease,and can be achieved by the therapies of clearing heat and purging fire,dispelling cold and removing dampness,and nourishing nutritive yin and harmonizing defensive qi with the appropriate formulas.The exploration of the treatment of diabetes mellitus and its complications from the pathogenesis and symptom characteristics of yellowish sweating disease will expand the thoughts for treating diabetic complications with traditional Chinese medicine.

Objective To explore the distribution patterns of tongue and pulse manifestations and traditional Chinese medicine(TCM)syndrome elements in ischemic stroke(IS)patients of different genders and ages,thus to provide approaches for the prevention and treatment of stroke with TCM.Methods The criteria of six syndrome elements in Diagnostic Scale of Syndrome Elements in Ischemic Stroke were used for the comprehensive identification of syndrome elements in 5 254 cases of inpatients confirmed as IS at the first visit in Shenzhen Traditional Chinese Medicine Hospital from 2017 to 2023.Moreover,the tongue proper,tongue coating,and whose pulse manifestations ranking in the top five in terms of the frequency of occurrence were collected for comparison and analysis.Results(1)For the distribution of TCM syndrome elements in 5 254 cases of IS patients,phlegm-dampness syndrome was the most common syndrome type(3 544 cases,67.5%),and then came qi deficiency syndrome(653 cases,12.4%)and yin deficiency syndrome(453 cases,8.6%).There were statistically significant differences in the distribution of phlegm-dampness syndrome,internal heat syndrome,and yin deficiency syndrome between the male and the female(P＜0.01).And the distribution of phlegm-dampness syndrome,qi deficiency syndrome,internal wind syndrome,and internal heat syndrome in the youth differed from that in the middle-aged and elderly(P＜0.01).(2)The tongue and pulse manifestations in IS patients with the leading six detection rates which ranked in descending order of frequency of occurrence were as follows:dull tongue(1 993 cases,37.9%),dark red tongue(1 907 cases,36.3%),thin and white coating(1 885 cases,35.9%),wiry and slippery pulse(1 714 cases,32.6%),white and greasy coating(1 679 cases,32.0%),and wiry and thready pulse(1 609 cases,30.6%).The detection rates of tongue and pulse manifestations such as light red tongue,thin and white coating in the youth group were significantly higher than those in the middle-aged and elderly group,and the detection rates of dark red tongue,and tooth-marked tongue in the middle-aged and elderly group were significantly higher than those in the youth group,the differences all being statistically significant(P＜0.05).The female patients had higher detection rates of dull tongue,thin and white coating,thin and yellow coating,wiry and thready pulse,and deep and thready pulse than male patients,while the male patients had higher detection rates of dark red tongue,red tongue,white and greasy coating,yellow and thick-greasy coating,white and thick-greasy coating,wiry and slippery pulse,and slippery pulse than the females,and the differences were all statistically significant(P＜0.05 or P＜0.01).Higher detection rate of thin and white coating was shown in the youth female than that in the youth male,while higher detection rate of wiry and slippery pulse was shown in the youth male than that in the youth female,and the differences were all statistically significant(P＜0.05 or P＜0.01).The middle-aged and elderly female patients had higher detection rates of dull tongue,thin and white coating,wiry and thready pulse,and deep and thready pulse than the middle-aged and elderly male patients,while the middle-aged and elderly male patients had higher detection rates of dark red tongue,red tongue,white and greasy coating,white and thick-greasy coating,yellow and thick-greasy coating,wiry and slippery pulse,and slippery pulse than the middle-aged and elderly female patients,the differences being all statistically significant(P＜0.05 or P＜0.01).Conclusion Phlegm-dampness syndrome,qi deficiency syndrome,and yin deficiency syndrome exert a significant effect on IS,and phlegm-dampness syndrome is the most common syndrome type.Factors such as gender and age have influences on the distribution of TCM syndrome in patients with IS.

OBJECTIVE To study the pharmacokinetic changes in the plasma and cerebrospinal fluid of bronchial asthma model rats after the complication of Ephedra sinica and Prunus armeniaca. METHODS SD male rats were randomly divided into blank group， model group， E. sinica group （12 g/kg， calculated by raw drug， similarly hereinafter）， P. armeniaca group （6 g/kg） and E. sinica-P. armeniaca drug-pair group （12 g/kg of E. sinica+6 g/kg of P. armeniaca）， with 6 rats in each group. Except for the blank group， the bronchial asthma model was induced by spraying rats in each group with an equal volume mixture of 2% acetylcholine chloride and 0.4% histamine phosphate， once a day， for 7 d. One hour before modeling every time， rats in each group were gavaged with the corresponding drug/normal saline， once a day， for 7 d. After the final administration and provocation of asthma， blood and cerebrospinal fluid collection were performed at different time points. The plasma and cerebrospinal fluid samples were pre-treated （with geranylgeranyl as the internal standard）， and the mass concentrations of ephedrine/pseudoephedrine， methyl ephedrine and amygdalin in both samples were determined by liquid chromatography-tandem mass spectrometry. DAS 2.0 pharmacokinetic software was used to determine the main pharmacokinetic parameters through the non-atrial chamber model and to compare the changes of the pharmacokinetic parameters before and after the combination of the two drugs. RESULTS Compared with E. sinica group， cmax and AUC0-21.33 h （or AUC0-10.67 h） of ephedrine/pseudoephedrine and methyl ephedrine in the plasma and cerebrospinal fluid of rats were significantly reduced in E. sinica-P. armeniaca drug-pair group， while CLZ/F and VZ/F were significantly increased （P＜0.05 or P＜0.01）； tmax of methyl ephedrine in the cerebrospinal fluid was significantly shortened （P＜ 0.05）.Compared with P. armeniaca group， the t1/2 of amygdalin in the plasma of rats in E. sinica-P. armeniaca drug-pair group was significantly shortened， and CLZ/F was significantly increased （P＜0.01）； the tmax of bitter amygdalin in the cerebrospinal fluid was significantly shortened， and the AUC0-10.67 h， CLZ/F， and VZ/F were significantly increased （P＜0.01）. CONCLUSIONS The combination of E. sinica and P. armeniaca accelerates the absorption and elimination of ephedra alkaloids， thus reducing the accumulation of ephedra alkaloids in the bronchial asthma model rats.

Objective To explore the effects of remote ischemic preconditioning combined with permissive hypercapnia on brain oxygen saturation and postoperative cognition in patients which undergoing thoracoscopic lung cancer surgery.Methods A collection of 64 patients elective requiring thoracoscopic lung cancer surgery who were divided into control group and combined group according to the randomized grouping method,with 32 cases in each group.The PaCO2 in the control group of patient was maintained at normal,and patients in the combination group were given permissive hypercapnia ventilation strategies and performed remote ischemic preconditioning,PaCO2 is maintained at 45-50mmHg(1mmHg=0.133kPa).Record the cerebral oxygen saturation(rSO2)at the five time points before operation(T0),10min after one lung ventilation(T1),30min after one lung ventilation(T2),10 min after lung recruitment(T3)and the end of surgery(T4),measured the internal jugular venous blood oxygen saturation(SjvO2)and calculated cerebral arteriovenous blood oxygen content difference(CaO2-CjvO2),brain oxygen uptake rate(CERO2).Monitored the average arterial pressure(MAP)and heart rate(HR)of the hemodynamic indicators at the above five time points.The scores of cognitive function were recorded 1 day before operation and 1 day and 3 days after operation;detected the levels of serum neuron-specific enolase(NSE),amyloid β(Aβ)and S100β protein(S100β)in 1 day before surgery,24hours after surgery and 48hours after surgery;Comparison of postoperative related indicators and adverse reactions between the patients of two groups.Results The rSO2 and SjvO2 of combined group were higher than control group in the T1-T4,but CaO2-CjvO2 and CERO2 were lower than those of control group.There was no significant difference in HR and MAP between two groups from T0-T4.The mini-mental state examination(MMSE)score of the combined group was significantly higher than that of the control group on the 1 day after operation.The level of serum NSE,Aβ and S100β in the combined group was lower than those of control group at 24hours and 48hours after operation.There was no significant difference in incidence of postoperative adverse reactions and postoperative related indexes between the two groups.Conclusion Permissive hypercapnia combined with remote ischemic preconditioning can increase cerebral oxygen saturation in patients undergoing thoracoscopic lung cancer surgery,improve cerebral oxygen metabolism and reduce the levels of serum neuron-specific enolase,β-amyloid protein and S100β protein,decrease the postoperative cognitive dysfunction.

Objective:To explore the therapeutic effect and safety of dexamethasone combined with ulinastatin in pa-tients with acute severe viral myocarditis(ASVMC).Methods:Clinical data of 92 ASVMC patients treated in our hospital from August 2018 to November 2020 were retrospectively collected,and divided into dexamethasone group(n=46)and combined treatment group(n=46,dexamethasone combined with ulinastatin)according to different treatment program.Each group received corresponding medication based on routine therapy for four weeks.Thera-peutic effect,levels of myocardial enzyme spectrum indexes[cardiac troponin Ⅰ(cTnⅠ),creatine kinase isoenzyme MB(CK-MB),lactate dehydrogenase(LDH)]and related indexes of cardiomyocyte apoptosis[soluble factor-related apoptosis(sFas),soluble factor-related apoptosis ligand(sFasL)]before and after treatment,and inci-dence of adverse reactions were compared between two groups.Results:The total effective rate(91.30％vs.73.91％)of combined treatment group was significantly higher than that of dexamethasone group(P=0.028).Compared with dexamethasone group,there were significant reductions in serum levels of cTnⅠ[(4.38±1.02)ng/ml vs.(1.76±0.24)ng/ml],CK-MB[(29.85±5.30)U/L vs.(20.26±4.18)U/L],LDH[(202.84±16.70)U/L vs.(184.21±12.63)U/L],sFas[(2.82±0.37)ng/L vs.(2.39±0.24)ng/L]and sFasL[(0.16±0.04)ng/L vs.(0.08±0.02)ng/L]in combined treatment group after 4-week treatment(P＜0.001 all).There was no sig-nificant difference in incidence rate of adverse reactions during treatment between two groups(P=0.711).Conclusion:Ulinastatin combined with dexamethasone can further inhibit myocardial cell apoptosis,and promote the improvement of myocardial function with significant therapeutic effect in patients with acute severe viral myocarditis and it's safe.
