Liver transplantation may be the best curative treatment for patients with cirrhosis and primary hepatocellular carcinoma. However, tumor recurrence and metastasis is still a difficult problem of liver trans-plantation. Postoperative adjuvant chemotherapy has been employed in an attempt to eliminate micrometasta-ses, and could improve long-term survival after LT for hepatocellular carcinoma. Although the specific chem-otherapy and its efficacy remain controversial, it has been widely used as a safe, feasible and effective meth-od in several clincial institutions.

Background Glucocorticoid drugs have been used increasingly in ophthalmology.It has been established that glucocorticoid are associated with a rise in intraocular pressure (IOP) and the development of glaucoma.Selective laser trabeculoplasty (SLT) is thought to be effective in treating patients with glucocorticoidinduced elevated IOP.Objective This study was to assess the efficacy of SLT in lowering IOP in patients with glucocorticoid-induced ocular hypertension.Methods A retrospective case series study was adopted.SLT around 360° chamber angle was performed in 9 eyes of 9 patients with glucocorticoid-induced glaucoma in Eye & ENT Hospital of Fudan University,including 5 eyes of 5 patients owing to use of glucocorticoid eye drops for long-term after laser in situ keratomileusis (LASIK) and 4 eyes of 4 patients who received intravitreal injection of 0.1 ml triamcinolone acetonide (TA) (4.0 mg) for macular edema induced by central retinal vein occlusion(CRVO).All of the patients were lack of preexisting glaucoma or ocular hypertension and underwent unsuccessful maximum tolerated medical therapy before SLT treatment.The base IOP was 35-44 mmHg and glucocorticoid drugs were ceased for 2-12 months prior to the SLT.The patients were followed-up for 6 months.IOP was measured and recorded before and 1 hour,1 week,1 month and 3 months,6 months after SLT.The difference of IOP was compared by repeated measures analysis of variance and multiple comparison analysis.Results All the patients received single SLT operation.The mean IOP was (40.0±2.9) mmHg before operation,but the IOP was (37.9±8.1),(34.9±5.9),(27.6±6.7),(21.6±6.9) and (17.9±2.9)mmHg 1 hour,1 week,1 month,3 months and 6 months after SLT.The IOP at 1 month,3 months and 6 months after SLT were significantly lower than that before operation (all at P＜0.05).Two patients received a filtration surgery for uncontrolled IOP at 1 month and 3 months after SLT respectively,and another patient still used 2 kinds of lowing-IOP eye drops until the end of following-up duration.Conclusions SLT reduce IOP in 6 eyes of 9 patients with glucocorticoid-induced increased IOP from the initial 1 month through 6 months after SLT.

This article was aimed to study the effect of pinellia combined with prunella vulgarisin of different ratios on the extraction yield of trigonellin and uracil, in order to investigate the changing disciplines and reasonable com-bination of Shuangxia Soup. A Welch Ultimate AQ-C18 column (4.6 mm×250 mm, 5 μm) was used in the study. The mobile phase, consisting of solvent A (water) and solvent B (acetonitrile) was programmed as a linear gradi-ent. The flow rate was 1.0 mL·min-1. And the detection wavelength was 265 nm. The column temperature was 25℃. HPLC was used in the determination of extraction yield of trigonellin and uracil for the comparison among different compatibilities. The results showed that the linearity was achieved in the range of 0.872-4.36 ng for trigonelline, and 10.8-50.4 ng for uracil. The average recoveries were 96.53%-101.48%, with RSD of 0.18%-4.26%. Com-pared with pinellia, the extraction yield of trigonelline was reduced and the extraction yield of uracil was increased after the compatibility. It was concluded that different compatibilities of Shuangxia Soup had effects on the extrac-tion yield of trigonelline and uracil. The best compatibility ratio still requires in-depth study.

Background and purpose:As a member of the catenin family, Delta-catenin protein could promote proliferation and invasion of tumor cells, but the accurate mechanism of Delta-catenin promoting cell proliferation is not clear. In the present study, we illustrated that Delta-catenin’s effect on cell apoptosis and their relationship with mitogen-activated protein kinase (MAPK) signaling pathway, and the possible mechanism was also explored for Delta-catenin promoting invasion and proliferation of tumor cells. Methods:The alterations of p38 and c-jun N-terminal rinasel JNK protein activity were detected in SPC and SK lung cancer cell lines with Delta-catenin overexpression or not, by Western blot method. At the same time, the apoptotic number of tumor cells was also examined by FCM method. Furthermore, the number of invasive tumor cells was examined by Matrigel invasive experiment. Results:Compared with untreated group and empty vector group, the activity of p38 protein was unchanged in lung cancer cell lines with Delta-catenin overexpressed (P>0.05), but the activity of JNK protein was decreased signiifcantly (P<0.05),meanwhile, apoptotic proportion of tumor cells were also reduced (P<0.05), and invasive ability of tumor cells was enhanced signiifcantly (P<0.05). Conclusion:Delta-catenin probably decreases apoptosis number of lung cancer cells via inhibiting the activity of JNK pathway, and then promotes invasive ability of tumor cells.

BACKGROUND: A large number of preclinical experimental data have shown that stem cells can regulate the immune function, and serve the function of cell replacement. OBJECTIVE: To summarize the anti-inflammatory effects of stem cells in the treatment of ischemic stroke, based on which, we further discuss the specific mechanisms. METHODS: We conducted a systematic and comprehensive search in PubMed, Elsevier, Springer, Wiley, Ovid, EBSCO databases. The range of retrieval time was from 2012 to 2017. The keywords were stem cells, stroke, inflammation, immune. Totally 110 articles were retrieved initially, and 47 articles were included in result analysis. RESULTS AND CONCLUSION: By reading extensive literature, we analyzed and summarized the research status quo of the anti-inflammatory effects of neural stem cells, mesenchymal stem cells and endothelial cells in the treatment of ischemic stroke. The mechanisms mainly include reducing focal inflammation, immune regulation, promoting the secretion of various neurotrophic factors, reducing secondary cell death, protecting neurons and promoting cell function recovery and further promoting the recovery of nerve function. The mechanisms underlying local immune regulation and anti-inflammatory effects of stem cells are mainly described as the shift from M1 to M2 macrophages under the intervention of stem cell factors, to intervene secreted immune cytokine profiles and exert effects on inhibition and polarization of glial cells. Further investigation is required on the anti-inflammatory effects and immune regulation of stem cell therapy for stroke.

Objective To observe the clinical effects on prevention of alveolar bone absorption by site preservation after tooth extraction due to periodontitis.Methods The experimental group consisted of 40 patients with 45 extracted teeth due to periodontitis.The fresh sockets were immediately grafted and filled with Bio-oss collagen and Bio-Gide after minimally invasive tooth extraction,while 40 teeth of control group were only treated with cotton balls bitten tightly over the socket for half an hour.Two groups were observed for changes in alveolar bone density by X-ray and cone beam CT (CBCT)after 6 months.Results There were the wound healing and no infection in extraction site of all patients with or without site preservation operation.The gingiva of extraction site was pink and tough in all groups.The alveolar bone loss in regular extraction patients significantly increased in horizontal and vertical aspects by X-ray and CBCT,while site preservation improved the alveolar bone defects (P<0.05).After site preservation for 6 months,CBCT analysis showed that the density of new alveolar bone markedly enhanced compared with regular extraction group.Conclusion The technique of site preservation after tooth extraction due to periodontitis is a method which can prevent and reduce disuse atrophy absorption of the alveolar ridge so that the height and width of the alveolar bone can meet aesthetic requirements.

ABSTRACT:Objective To investigate the effects of berberine on matrix metalloproteinases/tissue inhibitors of matrix metalloproteinases (MMPs/TIMPs) in rat periodontitis .Methods Adult male Sprague‐Dawley rats were subjected to thread ligation and porphyromonas gingivalis ( P . gingivalis ) inoculation resulting in periodontitis . Berberine [150 mg/(kg · d)] or vehicle was administered by oral gavage for 4 weeks .Alveolar bone loss and soft‐tissue destruction were determined by micro‐computed tomography (μ‐CT) and HE staining .The contents of tumor necrosis factor‐α(TNF‐α) and interleukin‐1β(IL‐1β) of gingival tissue were examined by ELISA .The expressions of MMP‐2 ,MMP‐9 and TIMP‐2 as well as the phosphorylation of P38 MAPK and NF‐κB were determined by Western blot .Results Significant increases were observed in alveolar bone loss and periodontal soft‐tissue destruction with higher levels of TNF‐α, IL‐1β and MMP‐2/9 expressions and the activities of P38 MAPK and NF‐κB in the experiment periodontitis group .Berberine of [150 mg/(kg · d)] not only improved the periodontal tissue and decreased alveolar bone loss ,but also reduced the contents of TNF‐α,IL‐1βand MMP‐2/9 and increased TIMP‐2 .In addition ,berberine inhibited the phosphorylation of P38 MAPK/NF‐κB .Conclusion Berberine protects against periodontal tissue damage via decreasing MMP‐2 and MMP‐9 expressions but increasing TIMP‐2 expression , which may be induced by inhibition of P38 MAPK/NF‐κB and the anti‐inflammatory effect on rat periodontitis .

Post-polio syndrome involves a variety of clinical manifestations, which need multi-dimensional evaluation measurement. Multi-dimensional Fatigue Inventory (MFI-20), muscle strength testing, laboratory test, imaging study, the sleep quality assessment, electro-physiological test, pain score, functional independence measure, moving obstacles evaluation, physical activity situation, walking ability as-sessment, the Medical Outcomes Study health survey short form, and evaluation of mental health scale are in common use in the studies.

Post-polio syndrome (PPS) usually appears decades after acute polio infection, characterized as progressive muscle weak-ness, fatigue, pain, muscle atrophy, poor endurance, intolerance of cold, sleep apnea, water choking cough, and difficulty in swallowing, etc., resulting in a decline in physical function. As an insidious disease, it is very important to identify and diagnose PPS.

Post-polio syndrome (PPS) is a syndrome after acute infection of poliovirus and sequelae of polio. The incidence of PPS is high, and more in old patients. The pathological features of PPS include chronic nerve damage affected muscles, result in fatigue, pain, breathing and sleep disorders, fall risk, and so on, which impair their health and quality of life. The hypotheses of pathogenesis of PPS in-clude over load of motor neurons, and the continuous existence of the poliovirus, etc. PPS is a stable neuromuscular disease progressing slowly.
