ABSTRACT
Aim To investigate whether notoginsenoside Rl (PNS-R1) alleviates allergic rhinitis (AR) through AMP-activated protein kinase (AMPK)/mitochondrial fission critical protein (DRP1) -mediated mitochondrial fission. Methods Different doses of PNSRl were used to treat ovalbumin (OVA) -induced AR model mice,and the inhibitory effect of PNS-R1 on AR was investigated by observing allergic symptoms such as nasal rubbing and sneezing, as well as HE staining of nasal tissues. Serum IgE levels and nasal lavage fluid (NLF) inflammatory cytokine levels were detected by enzyme-linked immunosorbent assay (ELISA) and apoptosis-related proteins were detected by Western blot. In vitro human nasal epithelial cells (HNEpC) were stimulated with IL-13 to observe apoptosis, mitochondrial membrane potential, cellular ROS and mitochondrial ROS production, as well as the expression levels of AMPK/DRP1, expression levels of the TXNIP/NLRP3 inflammasomes and the translocation of DRP1. Results PNS-R1 attenuated allergic symptoms in AR mice, HE staining reduced inflammatory cells and reduced the levels of OVA-specific IgE in serum, and the levels of IL-4, IL-6, and IL-8 in NLF. PNS-R1 attenuated the apoptosis and ROS production of nasal epithelial cells in AR. In vitro PNS-R1 could up-regulate mitochondrial membrane potential after IL-13 stimulation, reduce ROS and mtROS production, the proportion of apoptotic positive cells, and reduce cleaved caspase-3, Bax, and up-regulate Bcl-2 expression, down-regulate DRP1 phosphorylation (Ser 616) and DRP1 translocation at the mitochondrial membrane in an AMPK-dependent manner, reducing TXNIP/NLRP3 expression. Conclusions PNS-R1 can protect mitochondrial integrity by inhibiting the AMPK/DRP1 signaling axis and its subsequent TXNIP/NLRP3 signaling axis,thereby alleviating rhinitis in AR mice.
ABSTRACT
This study was carried out to know the frequency of occurrence of common anatomic variants in computed tomography of paranasal sinuses and nasal cavity. Non contrast Computed tomography (CT) of paranasal sinuses of 100 patients referred to Department Of Radiology, Saveetha Medical College were retrospectively studied. The Multi-detector computed tomography (MDCT) scans were evaluated for various anatomical variants of paranasal sinuses and nasal cavity. The frequency of occurrence was calculated in percentage.We found out that deviated nasal septum (DNS) was the most common variant in this study, seen in 86% of cases, followed by Agger nasi cells which was seen in 56% and the third most common was supra-orbital ethmoidal cells seen in 42% of the study population. All the cases included in the study, had minimum of one variant. Most of the study population showed multiple anatomical variations of paranasal sinus and nasal cavity. In conclusion, multidetector Computed tomography plays an important role is the assessment of various anatomical variants of the paranasal sinuses and nasal cavity. Pre-operative MDCT of Paranasal sinuses, gives the surgeons most if not all of the anatomical information they need to tailor surgeries. Considering the relatively high frequency of occurrence of these variants, it is essential for the radiologists to have a precise knowledge of imaging features of normal anatomy and anatomical variants of Paranasal sinuses.
ABSTRACT
In this experiment, Panax notoginseng saponins chitosan nanoparticles(PNS-NPs) were prepared by self-assembly and their appearance, particle size, encapsulation efficiency, drug loading, polydispersity index(PDI), Zeta potential, and microstructure were characterized. The prepared PNS-NPs were intact in structure, with an average particle size of(209±0.258) nm, encapsulation efficiency of 42.34%±0.28%, a drug loading of 37.63%±0.85%, and a Zeta potential of(39.8±3.122) mV. The intestinal absorption of PNS-NPs in rats was further studied. The established HPLC method of PNS was employed to investigate the effects of pH, perfusion rate, and different drugs(PNS raw materials, Xuesaitong Capsules, and PNS-NPs). The absorption rate constant(K_a) and apparent permeability coefficient(P_(app)) in the duodenum, jejunum, ileum, and colon were calculated and analyzed. As illustrated by the results, the intestinal absorption of PNS-NPs was increased in the perfusion solution at pH 6.8(P<0.05), and perfusion rate had no significant effect on the K_a and P_(app) of PNS-NPs. The intestinal absorption of PNS-NPs was significantly different from that of PNS raw materials and Xuesaitong Capsules(P<0.05), and the intestinal absorption of PNS-NPs was significantly improved.

SUMMARY: The aim of this study was to explore promoting effect of external applying Panax Notoginseng Saponins (PNS) on fractures. For this analysis 18 New Zealand male rabbits were divided into control group, splintage group and PNS group. All rabbits were performed left radius fractures and natural healing, splintage healing and splintage coated with PNS healing. 2 rabbits in each group were sacrificed on day 14, day 28 and day 42 after surgery, separately. Atomic force microscope scanning and nanoindentation tests were performed on the callus sections. The particle size and roughness in PNS group was both less than that in splintage group. The elastic modulus of callus in PNS group was consistent with normal bone tissue started from day 28 after surgery, two weeks earlier than that in splintage group. PNS could significantly reduce fracture healing time and increase strength of callus.
RESUMEN: El objetivo de este estudio fue evaluar el efecto de la aplicación externa de Panax Notoginseng Saponins (PNS) en fracturas óseas. Se usaron 18 conejos machos de raza Nueva Zelanda divididos en grupos control, entablillado y PNS. Se realizaron fracturas del radio izquierdo y cicatrización natural en todos los animales, además de la cicatrización con entablillado y entablillado recubierto con PNS. Se sacrificaron, posterior a la cirugía, dos conejos de cada grupo los día 14, 28 y 42. Se realizaron pruebas de escaneo con microscopio de fuerza atómica y nanoindentación en las secciones de callos. El tamaño de la partícula y la rugosidad en el grupo de PNS fue menor que en el grupo entablillado. El módulo elástico del callo en el grupo de PNS fue consistente con el tejido óseo normal iniciado el día 28 después de la cirugía, dos semanas antes que en el grupo de entablillado. El PNS podría redu- cir significativamente el tiempo de curación de la fractura y aumentar la fuerza del callo.

Resumo A disponibilidade de informações a respeito das minorias populacionais, nesse caso, da população LGBTQIA+ (Lésbicas, Gays, Bissexuais, Travestis e Transexuais, Queers, Intersexuais e Assexuais) e a possibilidade de cruzamentos com demais variáveis em bases populacionais é imprescindível para a compreensão das similaridades e especificidades da realidade vivenciada por estes grupos, bem como para a criação de políticas públicas focalizadas. Nesse sentido, buscamos refletir nesse artigo sobre os problemas relativos à investigação sobre as orientações/performances de sexo e gênero e, por consequência, a falta de informação sobre tal temática disponível nas bases de dados populacionais. A partir da inclusão da pergunta sobre orientação sexual na base de dados da Pesquisa Nacional de Saúde (PNS), de 2019, apesar das limitações, apresentamos algumas das possíveis oportunidades de investigações sobre o tema a partir de diferentes óticas.
Abstract The availability of information about population minorities, in this case, the LGBTQIA+ population (Lesbians, Gays, Bisexual, Transvestite/Transsexual, Queer, Intersex, and Asexual), and the possible intersections with other variables on population bases is essential for understanding the similarities and specificities of the reality experienced by these groups, and the establishment of focused public policies. In this sense, this paper aims to reflect on the problems related to research about the sex and gender orientations/performances and, consequently, the lack of information on this topic available in population databases. From the inclusion of the question about sexual orientation in the 2019 National Health Survey database, despite the limitations, this paper presents possible opportunities for investigations on the topic from different perspectives.

Abstract Cigarette consumption is a worldwide epidemic and its reduction is one of the major public health concerns. In Brazil, although there is a wide literature on smoking cessation it is restricted to experimental studies. Based on data from the 2013 National Health Survey (PNS), this study uses the survival methodology and use population data and consumer's profile to investigate which characteristics will affect smoking cessation hazard. The results showed that the people who are less likely to quit smoking are older, single men, with low income and fewer education years. They also do not practice physical exercise. The findings of cigarette cessation hazard to Brazilian population are similar of experimental studies with smokers and ex-smokers in country. Therefore, in order to decrease public health spending, Brazilian health policies regarding tobacco cessation could focus on those groups who will likely smoke for a long time.
Resumo O consumo de cigarro é uma epidemia mundial e sua redução é uma das principais preocupações de saúde pública. No Brasil, embora exista uma ampla literatura sobre a cessação do tabagismo, ela se restringe a estudos experimentais. Com base nos dados da Pesquisa Nacional de Saúde de 2013 (PNS), este estudo usa a metodologia de sobrevivência e usa dados da população e os perfis dos consumidores para investigar quais características afetarão as chances de cessação do tabagismo. Os resultados mostraram que as pessoas com menor probabilidade de parar de fumar são homens mais velhos e solteiros, com baixa renda e menos anos de estudo, que não praticam exercícios físicos. Os achados do risco de cessação do cigarro para a população brasileira são semelhantes a estudos experimentais com fumantes e ex-fumantes no país. Portanto, para diminuir os gastos em saúde pública, as políticas de saúde brasileiras em relação à cessação do tabaco poderiam se concentrar nos grupos que fumarão por mais tempo.

Objective:To explore the potential mechanisms of Panax Notoginseng Saponins （PNS） on growth inhibition of breast cancer cell line 4T1 in tumor-bearing mice by investigating the mitogen-activated protein kinase kinase kinase 1 （MEKK1）/stress activated protein kinase （SAPK）/extracellular regulated protein kinases （Erk） Kinase （SEK1）/c-Jun N-terminal kinase 1 （JNK1）/activator protein-1 （AP-1） signaling pathways. Method:The 4T1 breast cancer mice model was established. Forty-eight mice with successful modeled and randomly divided into the low， medium and high-dose PNS groups （10， 20， 40 mg·kg-1） and the model control group （12 mice in each group）. The PNS groups received intraperitoneal injection with dosage of 10 mL·kg-1， while the controlled group was given the same dosage of saline. After administration with PNS for 28 days， tumor tissues were isolated， weighed， sliced and homogenized. Tumor cell apoptosis was detected by TdT mediated-dUTP nick end labeling （TUNEL） staining. The mRNA expressions of MEKK1， SEK1， JNK1 and AP-1 in tumor tissue were detected by Real-time polymerase chain reaction（Real-time PCR）. The protein expressions of MEKK1， SEK1， JNK1 and AP-1 in tumor tissue were detected by immunofluorescence staining and Western blot. Result:Compared with model group， the tumor weights of medium-dose and high-dose PNS groups were decreased significantly （P<0.05）. TUNEL staining showed that the number of apoptotic tumor cells increased with the rise of dosage of PNS （P<0.05）. The medium-dose and high-dose PNS groups showed a significant increase in the mRNA expressions of MEKK1， SEK1， JNK1 and AP-1 as well as the protein expressions of MEKK1， SEK1， JNK1 and AP-1 in tumor tissues （P<0.05）， with statistically significant differences （P<0.05）. Conclusion:PNS could inhibit the tumor growth of breast cancer cell line 4T1 in tumor-bearing mice， which may be related to the activation of MEKK1/SEK1/JNK1/AP-1 signaling pathways.

ABSTRACT
Introducción: La infección por virus dengue es considerada una de las arbovirosis de mayor prevalencia en los países tropicales. La encefalomielitis diseminada aguda es un trastorno inflamatorio desmielinizante y multifocal que afecta al sistema nervioso central, de inicio agudo y curso clínico monofásico. El proceso inflamatorio se encuentra mediado por mecanismos inmunológicos y su relación con infecciones por el virus dengue aún no se establece con claridad. Objetivo: Describir un caso clínico con manifestaciones del sistema nervioso central después de una probable infección por el virus dengue. Presentación del caso: Paciente femenina de 50 años, con antecedentes de hipertensión arterial controlada. Quince días después de un cuadro de fiebre de 4 días de duración, que posiblemente fue por una infección por el virus dengue, comienza con síntomas y signos de afectación neurológica caracterizadas por ligera irritabilidad, dificultad para la concentración en una actividad específica de la vida cotidiana. Progresivamente se nota dificultad motora en el hemicuerpo izquierdo además de encontrarse agitada y distraída, motivo por el cual se decide su ingreso hospitalario. Se realiza el diagnóstico a través de los hallazgos en el examen físico, los estudios positivos de resonancia magnética nuclear y el resultado positivo de la IgM de dengue en sangre. Tanto la evolución clínica como la respuesta al tratamiento con esteroides fueron favorables. Conclusiones: El evento ocurrido en este caso sugiere que los facultativos deben tener presente el diagnóstico de encefalomielitis diseminada aguda en pacientes que han tenido infección previa o alta sospecha de esta por el virus dengue(AU)
Introduction: Dengue virus infection is one of the most prevalent arboviruses in tropical countries. Acute disseminated encephalomyelitis is an inflammatory demyelinating multifocal disorder affecting the central nervous system. Its onset is acute and its clinical course monophasic. The inflammatory process is mediated by immunological mechanisms, and its relationship to dengue virus infections is still not clear. Objective: Describe a clinical case of central nervous system manifestations after probable dengue virus infection. Case presentation: Female 50-year-old patient with a history of controlled hypertension. Fifteen days after a 4-day fever episode, possibly due to dengue virus infection, the patient starts presenting neurological signs and symptoms, such as slight irritability and difficulty to concentrate on a specific activity of daily living. The patient notices progressive motor difficulty in her left hemibody and she feels agitated and distracted. It is therefore decided for her to be hospitalized. A diagnosis is made based on physical examination findings, positive nuclear magnetic resonance studies, and the positive result of the dengue IgM blood test. Both the patient's clinical evolution and her response to treatment with steroids were favorable. Conclusions: The event herein described suggests that physicians should consider the diagnosis of acute disseminated encephalomyelitis in patients with previous infection or high suspicion of infection with dengue virus(AU)

Background: Deviation of the nasal septum (DNS) refers to the convexity of the septum to one side disturbing the nasal physiology with obstructed nasal breathing leading to lateral nasal wall abnormalities and paranasal sinuses (PNS) mucosal disease. Knowledge of nasal morphological parameters plays an important role in planning successful nasal surgery. Our aim was to evaluate the angle of septal deviation (ASD) on CT scan and study its influence on the lateral nasal wall abnormalities and PNS mucosal disease.Methods: A prospective cross-sectional observational study was conducted on 130 patients with clinical evidence of DNS and chronic sinusitis. The direction and severity of DNS was recorded on CT scan along with evaluation of lateral nasal wall and sinus mucosal abnormalities.Results: Increasing ASD had statistically significant correlation with the lateral nasal wall abnormalities, most commonly, contralateral middle and inferior turbinate hypertrophy (p-value <0.0001). No significant association was found with the incidence of ipsilateral or contralateral osteomeatal complex (OMC) obstruction and sinus mucosal disease.Conclusions: The direction and severity of septal deviation has significant impact on contralateral middle and inferior turbinate hypertrophy. The analysis of these ancillary pathologies can be of great help to the surgeon in better management of patients with nasal obstruction.
ABSTRACT
Objective To study the protective effect of Panax notoginseng saponins(PNS)and its components Rg1 and Rb1 on oxygen-glucose deprivation/reoxygenation(OGD/Reox)-induced tight junction damage. Methods Anaerobic box were used to induce OGD in HUVEC cells for 6 h followed by reoxygenation for 24 h. Transepithelial/endothelial electrical resistance(TEER)and cell permeability were detected,immunefluorescence was used to observe the ZO-1 and claudin-5 protein expression. Results PNS 20,40 mg/L and ginsenoside Rb1 significantly inhibited the OGD/Reox-induced decreased tight junction resistance,and the increased cell permeability(P< 0.05). PNS 20,40 mg/L and ginsenoside Rb1 partly restored the inter-cellular tight junctions which were regularly arranged on the cell membrane, and the cells displayed cobble stone-like arrangement. Conclusions PNS ameliorates ischemia-induced vascular endothelial cell tight junction damage via MMP-9 and VEGF/VEGFR2 signaling pathway. Rb1 is one of the effective monomer components.
ABSTRACT
Objective To retrospectively study the prognostic impact of paraneoplastic erythrocytosis (PE) on patients with hepatocellular carcinoma (HCC) after liver resection.Methods 713 patients with HCC who underwent partial hepatic resection in The Affiliated Cancer Hospital of Guangxi Medical University were divided into two groups:the PE group (n =81) and the non-PE group (n =632).The overall survival between the two groups were compared after reducing confounding bias by using propensity score matching (PSM).Independent prognostic predictors were determined by the Cox proportional hazards model.Results 80 pairs of patients were matched using PSM.In the matched cohort,the PE group exhibited significantly longer overall survival (OS) compared to the NPE group of patients without erythrocytosis.The 1-,3-,and 5-year overall survival rates were 88.6％,74.2％,69.0％ in the PE group,and 91.0％,60.1％,41.6％ in the non-PE group,respectively (P ＜ 0.05).Using the log-rank test,tumor size ≥ 10cm,macrovascular invasion,Barcelona Clinic Liver Cancer (BCLC) stage C,PE and complete tumor encapsulation were significantly associated with OS in patients with HCC after liver resection.The Cox regression analysis indicated that tumor size ≥ 10 cm,and Barcelona Clinic Liver Cancer (BCLC) stage C were independent prognostic factors of poor prognosis,while complete tumor encapsulation and paraneoplastic erythrocytosis were independent predictors of good prognosis.Conclusions For patients with HCC who underwent surgical resection,patients with PE had better prognosis than those without PE under the condition of similar tumor burden.PE was an independent predictor of good prognosis.
ABSTRACT
OBJECTIVE: To explore the effects of different bio-adhesive materials on in vitro adhesion and retention in artificial gastric acid fluid of Panax notoginseng saponins(PNS) bio-adhesive pellets. METHODS: PNS bio-adhesive pellets were prepared with different bio-adhesive materials.The in vitro adhesion of PNS bio-adhesive pellets was determined by the tissue retention method, using HPLC method to determine the contents of PNS(including notoginseng saponins R1, ginseng saponin Rg1 and ginseng saponin Rb1) retained in the pellets after a certain period of time in artificial gastric acid fluid. RESULTS: The contents of PNS retained in PNS bio-adhesive pellets prepared with chitosan and chitosan-carbomer after being placed in artificial gastric acid fluid for 2 h were the largest, which were (27.60±7.45)% and (19.80±3.55)% for R1, (27.01±5.49)% and (19.67±1.39)% for Rg1 and (47.07±6.26)% and (51.08±7.44)% for Rb1, respectively.For in vitro adhesion, HPMC and HPMC-carbomer combination was the best, followed by chitosan and chitosan-carbomer combination. CONCLUSION: PNS bio-adhesive pellets prepared with chitosan and chitosan-carbomer combination bio-adhesive materials can protect PNS from degradation in artificial gastric acid fluid and have good adhesion property.

ABSTRACT
Objective To study the inhibitory effect of panax notoginseng saponins (PNS) on 3-nitrotyrosine (3-NT) formation in brain induced by heme/NO2 -/H2O2 or ONOO - pathways in vitro. Methods According to the two major pathways of 3-NT formation in vivo, the models of protein nitration induced by heme/NaNO2/H2O2 or ONOO-system were established, respectively, in vitro. Bovine serum albumin (BSA)/rat plasma protein or rat brain homogenate protein were utilized as reactive substrates in both systems. Samples were divided into blank-control group, 3-NT group and PNS group (including low-, medium-and high-concentration subgroups). In 3-NT group, samples were exposed to heme/NaNO2/H2O2 or ONOO-system, respectively, at 37℃for 30 min, whereas in PNS group, samples were pre-incubated with PNS (at final concentrations of 50 mg/L, 100 mg/L, and 200 mg/L) at 37℃for 5 min before the nitrating system exposure. The 3-NT level in each group was detected by Western blot assy. Results Compared with the blank-control group, both heme/NaNO2/H2O2 and ONOO-system can induce significant 3-NT generation in BSA/rat plasma protein or rat brain homogenate protein (P0.05). Medium- and high-concentrations of PNS pre-treatment markedly inhibited 3-NT accumulation, with maximum effect at the concentration of 200 mg/L (P<0.05). Conclusion Medium- and high-concentrations of PNS can inhibit 3-NT formation in brain tissue mediated by either heme/NO2-/H2O2 or ONOO-pathways, implying that potential neuroprotective action against 3-NT involves pathological conditions, like trauma, stroke, and neurodegenerative diseases.
ABSTRACT
Objective]Based on 346 cases of PNS patients using glucocorticoids observed during treatment, the main symptoms, syndrome differentiation of syndrome type of traditional Chinese medicine(TCM) by induction, and discusses its the evolution regularity of TCM Syndromes.[Methods]Develop a unified observation table, then clinicians recorded symptoms, signs, tongue picture and type of pulse to log on to observe truthfully and un-mistakbly table, after the end of observation, comprehensive analysis by the four examination methods, using a unified standards for TCM syndrome type determination. Discussion after glucocorticoids treatment of patients with PNS TCM syndrome objective laws of evolution.[Result]First ,TCM syndrome evolution:the results show that:before hormone treatment, Qi deficiency of spleen and kidney and Yang deficiency of spleen and kidney have become the most important type of syndrome;hormone use initial stages 1~4 weeks, Qi deficiency of spleen and kidney, deficiency of Qi and Yin, when the hormone used for 5~8 weeks. Yin deficiency of liver and kidney and deficiency of Qi and Yin occupied the main position; during the hormone withdrawal stage, the deficiency of Qi and Yin increased significantly; in the hormone maintain stage it was mostly deficiency of Yin and Yang and Yang deficiency of spleen and kidney. As for demonstration, in hormone therapy before a lot of patients suffering from retention of water and turbid damp;After the treatment of 1~4 weeks it was mostly humid heat ,turbid damp and blood stasis;the accompanying symptoms were mostly humid heat, blood stasis and pathogenic factor of wind after the treatment of 5-8 weeks ;Miscellaneous accompanying symptoms were very conspicuous except retention of water in the treatment of hormone withdrawal stage; In the hormone maintaining stage, the highest proportion of blood stasis compared with others. The use of hormone therapy, humid heat and blood stasis were more prominent than others. Second, after the hormone treatment(1~8weeks) the relationship between efficacy and TCM syndromes: A total of 130 patients enrolled, the 96 patients with Yin deficiency syndrome, the rest of the patients had no deficiency of Yin syndrome. The results indicated that Yin deficiency syndrome group serum albumin and 24-hour urinary protein excretion efficacy than those without Yin deficiency syndrome group, with statistical significance.[Conclusion] Glucocorticoids should belong to pure Yang medicine in traditional Chinese medicine, the body under the action of pure Yang drugs are prone to Yin deficiency symptoms, suggests that the higher the sensitivity to drugs, the clinical remission rate is also higher. This can be applied in clinical glucocorticoids and observe the change of the patients with syndrome, early in the patients' sensitivity to the glucocorticoids.
ABSTRACT
Objective To study the effect of paeonol (PAE) and PNS on the expression of transforming growth factor (TGF)- beta 1/ Smad2/3 pathway in rats with acute myocardial infarction (AMI), and the possible molecular mechanism thereof. Methods Model of AMI was made using left anterior descending coronary branch ligation. According to the inter?vention methods rats were divided into model group, PAE group (8 mg·kg-1), PNS group (40 mg·kg-1), PAE (4 mg·kg-1)+PNS (20 mg·kg-1) low dose group, PAE (8 mg·kg-1)+PNS (40 mg·kg-1) high dose group and captopril positive control group (10 mg · kg-1). Rats without ligation were used as Sham operation group. Left ventricular systolic blood pressure (LVSP), left ventricular diastolic pressure (LVEDP) and the maximum rise and fall rate (/dtmax DP) were detected after 28-day treat?ment. HE staining was used to observe changes of myocardial tissue. The protein expression levels of TGF-β1 and Smad2/3 were detected by Western blot assay. Results There were significant differences in parameters used for detecting treatment group and model group, formula group and single drug group, formula high dose group and formula low dose group (P <0.01). The model group showed pathological changes. All treatment groups showed different degrees of pathological improve?ment. There was the most significant improvement in formulae group and captopril group. Compared with the model group, TGF-β1 and Smad2/3 protein expressions were decreased in treatment group. The expression levels of TGF-β1 and Smad2/3 were significantly decreased in formula group than those of PAE group and PNS group, and lower levels in formula high dose group than those of formula low dose group (P<0.05). Conclusion Paeonol and PNS can inhibit the expressions of TGF-β/Smad 2/3 protein in rats with AMI, by blocking TGF-β/Smad pathway.
ABSTRACT
OBJECTIVE: To investigate the absorption kinetics of Panax notoginseng saponins (PNS) in rat small intestines and the effects of bioadhesive materials on the absorptive kinetics and appearance permeability. METHODS: HPLC was used to determine the concentrations of Panax notoginseng saponins. An in situ single pass intestinal perfusion was used to investigate the absorption of Panax notoginseng saponins in rat small intestines (duodenum and jejunum-ileum). RESULTS: In duodenum and jejunum-ileum, Panax notoginseng saponins at different concentrations (0.5-2 mg · mL-1) had no significant effect on the absorptive kinetics and appearance permeability of small intestines (P > 0.05), respectively. Some bioadhesive materials (include chitosan, carbomer 934P, 941P, Konjac glucan and HPMC K4M) could promote the absorption of Panax notoginseng saponins in small intestines, this effect was more obvious in duodenum area. HPMC K15M has no effect on the PNS absorption in small intestines(P > 0.05), pectin could even delay the absorption to some extent. CONCLUSION: Panax notoginseng saponins has a poor absorption in small intestines, the passive diffusion mechanism take great part in its transport progress. Some bioadhesive materials could enhance the permeability of Panax notoginseng saponins on the small intestine wall.
ABSTRACT
Aim To investigate the effects of panax nonstaining saponins ( PNS ) on the apoptosis of renal cells induced by cisplatin through the path of mitochon-drion . Methods Male Sprague-Dawley( SD) rats were randomized divided into normal control group, cisplatin model group and the cisplatin+PNS group,with 12 rats of each group. Animals were sacrificed to determine the N-acetyl-β-D-Glucosaminidase ( NAG ) in urine, blood urea nitrogen ( BUN) and serum creatinine ( Cr) concentrations after 8d of intraperitoneal injection. HE-staining was employed to observe renal pathologies. Transmission electron microscopy ( TEM ) was em-ployed to observe the mitochondria of the rats′ injured kidney region. TUNEL staining was employed to detect the distribution of apoptotic cells. Immunnohistochem-istry was used to detect Bax and caspase-9 expression, and expression of Bcl-2 protein was detected by West-ern blot. Results Compared with the normal control group, contents of BUN, serum Cr and urinary NAG levels of rat in the cisplatin model group were increased ( P <0. 01 ) , and some mitochondria of the epithelial cells of renal tubules got injured seriously. The apopto-sis rate of kidney cell was increased ( P<0. 01 ) . The expression of Bax,caspase-9 and Bcl-2 proteins was in-creased ( P < 0. 01 ) . Compared with the cisplatin model group, contents of BUN, serum Cr and urinary NAG levels of rats in the cisplatin model group were decreased ( P <0. 01 ) , and some mitochondria of the epithelial cells of renal tubules were significantly im-proved. The apoptosis rate of kidney cell was decreased ( P<0. 01 ) . The expression of Bax and caspase-9 pro-tein was decreased (P<0. 01),but Bcl-2 protein was increased ( P < 0. 01 ) . Conclusion PNS may in-crease the expression of Bcl-2 protein and decrease the expression of Bax and caspase-9 proteins, which may play a protective role in cisplatin nephritic damage.
ABSTRACT
Objective To study the effects of panax notoginseng saponins (PNS)on rat superficial renal medulla cells after femoral fracture and to discuss the protective role of PNS in renal injury after fracture. Methods We divided 102 Wistar rats randomly into simple fracture group (n =36),fracture and medication group (n =36)and normal control group (n =30).In the former two groups 6 rats were respectively executed at 1,6,12, 24,36,48 h after fracture modeling,while 5 rats in normal control group were executed at the corresponding time points.Regular HE staining was used to observe pathological changes and TUNEL was used for apoptotic cells.And immunohistochemistry and in situ hybridization were used to detect the expressions of Bcl-2 and Bax in superficial renal medulla tissues.Results In simple fracture group,mild granular degeneration could be seen in renal tubular epithelial cells of superficial renal medulla and the interstitial small vessels were slightly expanded and congested. Compared with simple fracture group,the lesions were slighter in fracture and medication group.In simple fracture group,Bcl-2 and Bcl-2 mRNA expressions were significantly higher than those in normal control group at 1 -36 h (P <0.01).Bax expression was higher than that in normal control group at 12-36 h (P <0.01),and Bax mRNA expression was higher than that in normal control group after 6 h after fracture (P < 0.01 ).In fracture and medication group,Bcl-2 expression was obviously higher than that in simple fracture group at 1 h (P <0.01),and Bcl-2 mRNA expression was higher than that in simple fracture group at 1 -48 h (P <0.01).Bax and Bax mRNA expressions were both lower than those in simple fracture group at 1 - 48 h (P < 0.01 ).Conclusion Fracture trauma has significant influences on protein expression and mRNA transcription of Bcl-2 and Bax in superficial renal medulla.PNS can upregulate anti-apoptosis gene Bcl-2 and downregulate pro-apoptosis gene Bax,thus playing the role of inhibiting tissue cell apoptosis.
