Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

OBJECTIVE: To evaluate the efficacy and safety of Pai-Neng-Da Capsule (, panaxadiol saponins component, PNDC) in combination with the cyclosporine and androgen for patients with chronic aplastic anemia (CAA). METHODS: A total of 79 CAA patients was randomly divided into 2 groups by a random number table, including PCA group [43 cases, orally PNDC 320 mg/d plus cyclosporine 5 mg/(kg·d) plus andriol 80 mg/d] and CA group [36 cases, orally cyclosporine 5 mg/(kg·d) plus andriol 160 mg/d]. All patients were treated and followed-up for 6 treatment courses over 24 weeks. The complete blood counts, score of Chinese medical (CM) symptoms were assessed and urine routine, electrocardiogram, hepatic and renal function were observed for safety evaluation. Female masculinization rating scale was established according to the actual clinical manifestations to evaluate the accurate degree of masculinization in female CAA patients treated by andriol. RESULTS: The effective rates were 88.1% (37/42) in the PCA group and 77.8% (28/36) in the CA group based on the standard for the therapeutic efficacy evaluation of hematopathy. There was no significant difference in the white blood cell (WBC) counts, platelet counts and hemoglobin concentration of peripheral blood between two groups after 6 months treatment. The masculinization score of female patient in the PCA group was significantly lower than the CA group (P<0.05). The mild abdominal distention was observed in 1 cases in the PCA group. In CA group, the abnormalities in the hepatic function developed in 2 cases and the renal disfunction was found in 1 case. CONCLUSION The PNDC possesses certain curative effects in the treatment of CAA without obvious side-effects and can partially replace andriol thereby to reduce the degree of masculinization [Registried at Chinese Clinical Trial Registry (ChicTR1900028153)].

The differences of the active ingredients in Dendrobium huoshanense of different growth years and their protective effects on acute liver injury were studied to provide evidence for optimizing harvest time. The contents of polysaccharides, total flavonoids and total alkaloids in D. huoshanense of different growth years were determined by UV spectrophotometry, and the contents of gigantol in D. huoshanense were determined by HPLC. C57 BL/6 mice were randomly divided into blank control group(saline), modeling group(saline), high-dose(7.5 g·kg~(-1)) and low-dose(1.25 g·kg~(-1)) groups of D. huoshanense of different growth years. Each group was intragastrically administered every day for 2 weeks. 500 mg·kg~(-1) paracetamol was injected intraperitoneally 2 h after last treatment except the control group. After 12 hours, the serum and liver tissues were collected to detect the activities of ALT and AST, and the levels of SOD and MDA. The hepatic histopathological examination was performed. The results showed that the chemical constituents of D. huo-shanense of different growth years were significantly different(P<0.05). The contents of polysaccharide and gigantol of D. huoshanense of 2 growth years were the highest. The contents of flavonoids and alkaloids of D. huoshanense of 3 growth years were the hig-hest, followed by the D. huoshanense of 2 growth years, and the lowest were that of 1 growth year. Compared with the modeling group, D. huoshanense of different growth years could decrease the activities of ALT and AST in serum. Meanwhile, the levels of MDA reduced significantly, while those of SOD increased markedly. Histopathological results suggested that all D. huoshanense samples were effective in the reduction of the necrosis of hepatocytes in different degrees. The results of the multi-component SPSS paired tests showed that polysaccharide and gigantol probably played a leading role in the liver protection effects, while D. huoshanense of 2 growth years showed the best efficacy. The optimal harvesting time of D. huoshanense is 2 growth years.

BACKGROUND: The basis of individualized treatment should be individualized mortality risk predictive information. The present study aimed to develop an online individual mortality risk predictive tool for acute-on-chronic liver failure (ACLF) patients based on a random survival forest (RSF) algorithm. METHODS: The current study retrospectively enrolled ACLF patients from the Department of Infectious Diseases of The First People's Hospital of Foshan, Shunde Hospital of Southern Medical University, and Jiangmen Central Hospital. Two hundred seventy-six consecutive ACLF patients were included in the present study as a model cohort (n = 276). Then the current study constructed a validation cohort by drawing patients from the model dataset based on the resampling method (n = 276). The RSF algorithm was used to develop an individual prognostic model for ACLF patients. The Brier score was used to evaluate the diagnostic accuracy of prognostic models. The weighted mean rank estimation method was used to compare the differences between the areas under the time-dependent ROC curves (AUROCs) of prognostic models. RESULTS: Multivariate Cox regression identified hepatic encephalopathy (HE), age, serum sodium level, acute kidney injury (AKI), red cell distribution width (RDW), and international normalization index (INR) as independent risk factors for ACLF patients. A simplified RSF model was developed based on these previous risk factors. The AUROCs for predicting 3-, 6-, and 12-month mortality were 0.916, 0.916, and 0.905 for the RSF model and 0.872, 0.866, and 0.848 for the Cox model in the model cohort, respectively. The Brier scores were 0.119, 0.119, and 0.128 for the RSF model and 0.138, 0.146, and 0.156 for the Cox model, respectively. The nonparametric comparison suggested that the RSF model was superior to the Cox model for predicting the prognosis of ACLF patients. CONCLUSIONS The current study developed a novel online individual mortality risk predictive tool that could predict individual mortality risk predictive curves for individual patients. Additionally, the current online individual mortality risk predictive tool could further provide predicted mortality percentages and 95% confidence intervals at user-defined time points.

Objective:To compare the biomechanical characteristics and cognitive task performance of the young and the old adults as ascending and descending staircase. Methods:From March to April, 2018, 25 volunteers, including twelve old persons aged (71.54±3.25) and 13 young persons aged (22.24±1.56), were tested with continuous minus seven as sitting (pre-test), walking up and down stairs, walking up and down stairs with continuous minus seven and continuous minus seven as sitting again (post-test). Results:The performance of continuous minus seven was better as walking up stairs and post-test than pre-test in the old persons, and it was better as both up and down stairs, as well as post-test than pre-test in the young persons. As walking up stairs, the main effects of both age (F > 5.037,P < 0.05) and task (F > 6.122,P < 0.05) were significant in walking time, step length, frequency and speed; while walking down stairs, the main effects of both age (F > 17.252,P < 0.01) and task (F > 6.274,P < 0.05) were significant in walking time, step frequency and speed. Conclusion:People would alter the focus on cognitive tasks according to the difficulty of the action. The old adults would be more conservative in the action as upstair during the dual task, and would pay less attention to cognitive task additionally as downstair.

The present situation of the clinical application of dog-days moxibustion (moxibustion applied in the three periods of the hot season) is summarized so as to provide the guide for the theoretic study and clinical application of dog-days moxibustion. The intervention time of dog-days moxibustion is on the 1st day of each of the three periods of the hot season. Simultaneously, the geographic factors are considered. The disorders of lung system are mostly dominant among the indications of dog-days moxibustion, complicated with spleen and stomach disorders as well as cold and deficiency syndromes/patterns. The acupoints are mainly selected from the front- points on the chest and the back- points on the back, in combination with the differentiation of diseases, symptoms/patterns and the disorder stages. The duration of treatment is ranged from 1 to 3 years. The clinical therapeutic effect is improved constantly along with the increase of treatment periods by years.

Objective:The present study was to observe the effect of Qianjin Weijingtang on the differentiation of helper T cells 17 （Th17）/T regulatory cell （Treg） and the expressions of related cytokines in the lung tissues of the model rats exposed to cigarette smoke. Method:Totolly 60 male rats were randomly assigned into six groups （control group， model group， acetylcysteine group and Qianjin Weijingtang high， moddle and low dose groups）， with 10 rats in each group. After 30 day's modeling and 30 day's intervention， rats were killed peacefully with their tissues collected. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） was used to detect the expression of retinoic acid associated orphan receptor （ROR-γt） and forkhead/pterygoid helix transcription factor 3 （Foxp3） mRNA， enzyme-linked immunosorbent assay （ELISA） was used to check the concentration of interleukin-17（IL-17）， IL-6， IL-10 and transforming growth factor-β₁（TGF-β₁）. Htoxylin eosin （HE） staining was used to observe the pathological changes of lung tissues， while flow cytometry was used to detect Treg（Foxp3⁺CD25⁺）， Th17（CD4⁺IL-17⁺） and Treg/Th17 ratio. Result:As compared with the control group， the ROR-γt mRNA expression in model group was higher（P<0.01）. As compared with the model group， various doses of Qianjin Weijingtang down-regulated the expression（P<0.05，P<0.01）. As compared with the control group， the expression of the Foxp3 mRNA was down-regulated in model group（P<0.05）， but was up-regulated in Qianjin Weijingtang middle and low dose groups（P<0.05）. Compared with the control group， the concentration of IL-17 and IL-6 in the model group were significantly increased， while the concentration of IL-10 and TGF-β₁ in the model group were significantly decreased（P<0.05，P<0.01）. As compared with the model group， intervention with various doses of Qianjin Weijingtang could help to decrease the concentration of IL-17 and IL-6 in lung tissues， and increase the concentration of IL-10（P<0.05）， which were consistent with those of Real-time PCR results. Flow cytometry examination showed that the Th17（CD4⁺IL-17⁺） proportion decreased and Treg/Th17 ratio increased after Qianjin Weijing Tang middle and low dose intervention（P<0.05，P<0.01）. Conclusion:Qianjin Weijingtang could regulate Treg/Th17 ratio and help to achieve Th17/Treg balance.
