ABSTRACT
Objective: To observe the clinical efficacy of pediatric Tuina (Chinese therapeutic massage) plus oral administration of Chinese medication for pediatric anorexia due to spleen failing in transportation. Methods: A total of 94 children with anorexia due to spleen failing in transportation were randomized into an observation group and a control group by the random number table method at a ratio of 1:1, with 47 cases in each group. The control group was treated with modified Bu Huan Jin Zheng Qi San, and the observation group was treated with additional Tuina manipulation of Yun Shui Ru Tu based on the treatment in the control group. After 4 weeks of treatment, the clinical efficacy of the two groups was observed, and the traditional Chinese medicine (TCM) symptom score, serum leptin, neuropeptide Y, and serum zinc and calcium levels were compared. Results: After 4 weeks of treatment, the total effective rate of the observation group was 87.2％, and that of the control group was 74.5％. The difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). After treatment, the serum leptin level in both groups decreased, and the level in the observation group was lower than that in the control group (P<0.05). The serum neuropeptide Y, zinc, and calcium levels in both groups increased after treatment, and the levels in the observation group were higher than those in the control group (P<0.05). Conclusion: Tuina manipulation of Yun Shui Ru Tu plus oral administration of Chinese medication is significantly effective in treating pediatric anorexia due to spleen failing in transportation, which can improve the appetite of children and improve the symptoms of anorexia, and the curative effect is better than that of oral administration of Chinese medication alone.

Intracranial aneurysms will lead to subarachnoid hemorrhage, which has a high mortality and morbidity risk. Screening high-risk aneurysms for preventive intervention has a positive effect, considering the widespread presence of unruptured aneurysms in the general population, this article reviews the risk factors of aneurysm rupture from the aspects of epidemiology, pathology, morphology and hemodynamics. In terms of epidemiology, smoking history, hypertension, age, gender and family inheritance are all closely related to the risk of aneurysm rupture. In terms of pathology, inflammation on the wall of intracranial aneurysm may be related to the risk of aneurysm rupture. In imaging, the size of intracranial aneurysms, location, the characteristics of the artery wall and some morphological and hemodynamic parameters can be used as evaluation index of fracture risk factors, at the same time the growth of intracranial aneurysm is one of the high risk indicators, the indicators for us in the future to establish intracranial unruptured aneurysms rupture risk factors evaluation model is of great significance.
ABSTRACT
Objective:To carry out germplasm resource evaluation and new variety breeding of <italic>Murraya paniculata</italic> and improve the germplasm quality， so as to ensure the demand， yield and quality of medicinal materials. Method:Following resource investigation and collection， 17 traits of 107 <italic>M. paniculata</italic> germplasm samples， like plant type， basal diameter， leaf shape， leaf length， and leaf width were determined and then subjected to principal component analysis and factor analysis for screening the principal component factors. Nine primary traits were selected as variables for further cluster analysis using Ward's method and Euclidean distance. According to the characteristics of medicinal parts， the core germplasms were screened out. Then the contents of auxin， zeatin， zeatin nucleoside， isopentenyl adenine， isopentenyl adenine riboside， dihydrozeatin， and dihydrozeatinriboside in the leaves were measured by ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）， followed by their correlation analysis with agronomic trait. Result:The variation coefficients of petiole length， branching number， and basal diameter were large. The nine main factors could be classified into four categories， with a contribution rate of 72.822%. The cluster analysis with Ward's method and Euclidean distance showed that 107 germplasm samples were clustered into six clusters and 61 core germplasms were identified. Such traits as leaf length， leaf width， petiole length， leaf surface， and petiole color were found to play an important role in the classification of <italic>M. paniculata</italic> germplasms. The content of zeatin nucleoside exhibited significant positive correlations with leaf length （<italic>P</italic><0.01）， petiole length （<italic>P</italic><0.01）， and leaf width （<italic>P</italic><0.05）. Conclusion:These results have laid the foundation for further selection and breeding of <italic>M. paniculata</italic> new varieties.
ABSTRACT
The posterior gastric mesentery is one of the six mesenteries of the stomach in the membrane anatomy theory. It locates in the upper area of the pancreas, surrounds the posterior gastric vessels, and is adjacent to the short gastric mesentery by the left side, and is adjacent to the left gastric mesentery by the right side, which fixes the fundus body to the posterior abdominal wall of the upper area of pancreas. Due to its anatomical structure, in complete mesentery excision (CME)+D2 surgery, it is a surgical approach to deal with gastric mesentery in the upper area of pancreas; the second step of the "Huang's three-step method" corresponds to the posterior gastric mesentery in the theory of membrane anatomy. In the surgery of benign diseases of the stomach, laparoscopic sleeve gastrectomy (LSG) and laparoscopic Nissen fundoplication, if the short gastric vessels are difficult to be exposed and safely divided, we can dissect the posterior gastric mesentery firstly, and then hoist the fundus of the stomach in order to help dissection of the short gastric vessels. The membrane anatomy theory, as a frontier theory, provides us the new surgical perspectives and paths in gastric surgery.

Objective To compare the levels of short-chain fatty acids produced by high-fiber diet and low-fiber diet in the intestinal metabolism of mice for exploring the effects of different fiber diets on the activation and function of microglia in mouse brain. Methods Mice fed with low-fiber and high-fiber diets were detected for the levels of three major short-chain fatty acids (acetic acid, propionic acid, butyrate) in the cecum. The distributions of microglia in the brain of different diet mice were compared by immunofluorescence. Real-time fluorescence quantitative PCR was used to detect expressions of genes associated with microglia activation in mouse brain between the above two groups of mice. Results The acetate level in the cecum of mice in high fiber diet group was higher than that of mice in low fiber diet group. There were no significant differences between the two groups in the levels of propionic acid and butyrate and the number and distribution of microglia. However, the levels of microglial activation-associated inflammatory cytokines such as IL-1β, IL-6, TNF-α, IL-12, CCL2, CCL5 and CCL7 mRNA were higher in high fiber diet group than in low fiber diet group after the intracranial stimulation by LPS. Conclusion The quantity of fiber in the diet after weaning can affect the maturation and activation of microglia in the brain, which may because of different levels of acetic acid after metabolism of different dietary structures by the intestinal flora.
ABSTRACT
Objective To investigate the protective effect of prenatal astaxanthin treatment against cognitive impairment in adult offspring induced by exposure to maternal seizures in utero.Methods Female adult Sprague-Dawley rats were randomly divided into four groups:control group,astaxanthin group,kindling group and kindling+astaxanthin group.Each rat was implanted with electrodes.Those in the kindling and kindling+astaxanthin groups were kindled once a day by electrical stimulation of the amygdala.All rats were allowed to mate after one week's amygdala kindling.Rats in the kindling and kindling+astaxanthin groups continued to be treated with electrical stimulation every 48 hours from gestational day 1 to 20,and those in the astaxanthin and kindling+astaxanthin groups were injected intraperitoneally with 30 mg/(kg · d) of astaxanthin simultaneously.Naturally delivered offspring were raised till 12 weeks of age.Morris water maze test was performed to assess the cognitive function of adult offspring.Changes in the morphology of hippocampus were observed with Nissal's staining and transmission electron microscope.Expression of cyclic adenosine monophosphate response element binding protein (CREB) and brain-derived neurotrophic factor (BDNF) in adult offsprings' hippocampus tissues at protein and mRNA levels were determined using Western-blotting and reverse transcription-polymerase chain reaction.Analysis of variance and LSD test were used as statistical methods.Results Morris water maze test showed that from the 3rd day to the 5th day,the kindling group had significantly longer escape latency [(36.33 ±7.85),(28.80± 8.41),(29.50± 11.72) s] than the control [(28.90±7.46),(17.59±9.12),(10.40±3.69) s] and kindling+astaxanthin groups [(28.30±5.75),(18.37±3.39),(15.23±6.63) s] (F=3.601,9.811 and 14.226,all P＜0.05).In probe trials,the kindling group had significantly fewer platform crossings as compared with the control and kindling+astaxanthin groups [(4.40± 1.71) vs (7.20± 1.62) and (6.50±1.84) times,F=6.586,P=0.001].The kindling group spent dramatically less time in the target quadrant than the control and kindling+astaxanthin groups [(27.35±7.63) vs (58.29± 10.48) and (40.41 ± 7.06) s,F=25.825,P＜0.001].Nissl staining showed that hippocampal neurons of offspring in the control group were normal,but there was hippocampal damage in the kindling group and the damage was more severe than that in the kindling+astaxanthin group.Electron microscope observation showed that neurons and synapses in the hippocampal CA1 area of offspring in the control group were normal.However,obvious damage to neurons and synapses was induced in the kindling group and that was worse than the damage induced in the kindling+astaxanthin group.Expression of CREB and BDNF protein in the kindling group (0.19±0.06and 0.32 ±0.04,respectively) were significantly lower than those in the control (0.81 ±0.11 and 0.93 ± 0.04,respectively) and kindling+astaxanthin groups (0.60± 0.07 and 0.80±0.06,respectively) (F were 34.015and 71.074,both P＜0.001).Moreover,the kindling group showed decreased expression of CREB and BDNF mRNA (0.48 ± 0.11 and 0.43± 0.08,respectively) as compared with the control (1.02± 0.65 and 0.99± 0.09,respectively) and kindling+astaxanthin groups (0.89±0.15 and 0.96±0.13,respectively) (F were 13.447 and 21.912,both P＜0.01).Conclusion Treatment with astaxanthin could ameliorate the cognitive impairment and pathological damage in hippocampus of adult offspring induced by exposure to maternal seizures in utero through regulating the CREB-BDNF signal pathway.
ABSTRACT
Objective To explore the importance of head fixation in chest wall field combined with supraclavicular field radiotherapy for breast cancer by comparing the displacement error and dosimetric differences caused by multi-functional body board and breast bracket.Methods Thirty patients with breast cancer were randomly divided into groups A and B.In group A,patients were fixed with multi-functional body board and head thermoplastic film.In group B,patients were fixed with traditional breast brackets.Each patient received CBCT scan before and after radiotherapy.Both setup errors and intra-fractional displacements in the x-,y-and z-axis,V100 and V95 were calculated.Statistical analyses were performed using the independent sample t-test.Results The displacement errors in groups A and B before and after radiotherapy were (1.24± 0.42),(1.71± 0.61) and (2.25± 1.04) mm vs.(3.67± 2.05),(3.78± 1.74),(4.65±2.66) mm in the x-,y-and z-axis,respectively (P=0.033,0.027,0.020).The intra-fractional displacements in groups A and B were (1.10±0.66),(1.13±0.59),(1.11 ±0.62) mm vs.(2.48±0.88),(2.21 ±0.98),(3.53±2.01) mm in the x-,y-and z-axis,respectively (P=0.030,0.021,0.013).The V100 in groups A and B were (94.27± 3.20) ％ and (99.08± 0.60) ％ (P =0.065),and (89.48± 4.70) ％ and (96.53± 2.50) ％ for V95 (P =0.002),respectively.Conclusion The risk of displacement error is significantly reduced using multi-functional body board,which enhances the accuracy of radiation dose in chest wall and supraclavicular fields of breast cancer patients.
ABSTRACT
Objective To investigate the effect of platelet-rich plasma(PRP) combined with bone graft in the treatment of humeral condylar bone defect.Methods A total of 135 patients with humeral condylar bone defect in Ankang central hospital from January 2012 to December 2015 were divided into the PRP combined group(n =69) and the conventional group(n =66) according to the order of admission time.The patients of PRP combined group were treated with platelet-rich plasma combined with autologous bone graft,and patients of conventional group received autologous bone graft,respectively.The surgery time,hospitalization time,wound healing,fracture union and the motion of elbow joint at postoperative 1 year between two groups were compared.The Kaplan-Meier survival curve was used to reflect the bone healing in both groups,and the log-rank test was used to compare the result.Results There was no statistically significant difference in the surgery time,hospitalization time,wound healing and motion of elbow joint at postoperative 1 year between the two groups(P ＞ 0.05).But the average time of wound healing (3.8 ± 0.72) weeks and the time of bone union (18.8 ± 3.50) weeks in PRP combined group were significantly shorter than (6.4 ±0.58) weeks and (22.7 ± 1.55) weeks in the conventional group(P =0.000),the differences were significant.The KaplanMeier survival curve of the bone union in the PRP combined group was also significantly better than that in the conventional group.Conclusion PRP can promote the healing of fracture in patients with humeral condylar bone defect after autologous bone graft,which contributes to the recovery of elbow function.
ABSTRACT
Objective To observe the significance of preoperative peripheral serum inflammatory cyto-kines and blood routine in predicting postoperative DVT in patients with neurosurgery.Methods A total of 156 pa-tients from the Department of Neurosurgery form April 2016 to April 2017 were recruited in this study.According to the incidence of postoperative deep venous thrombosis(DVT),patients were divided into DVT group(48 cases) and non-DVT group(108 cases). The date blood routine(including hematocrit,hemoglobin,neutrophil count, monocyte count,white blood cell count,platelet count)and serum inflammatory cytokines(including TNF-α,IL-1β,IL-1β,IL-6,IL-8)of two groups by t tests were compared.The possible risk factors for postoperative DVT in neurosurgical patients were analyzed by multivariate analysis logistic regression.The predicted cutoff value is deter-mined by plotting the subject's working characteristic(ROC)curve.Results Between the control group and DVT group,there were significant differences in preoperative blood neutrophil count,hemoglobin,TNF-α,IL-6 and IL-8(P < 0.05). Multivariate analysis logistic regression showed that the level of neutrophil count and concentration of serum TNF-α concentration were increased,indicating they may be the risk factors of DVT.For the neutrophilic granulocyte count,the value of specificity and sensibility was 82.7%and 61.7%respectively.For the TNF-α level, the value of specificity was 72.3% and the value of sensibility was 83.1%. Conclusion The level of preoperative neutrophil count and the concentration of TNF-α have value in predicting the occurrence of postoperative DVT in neurosurgical patients.

ABSTRACT
A mangiferin aglycon derivative J99745 has been identified as a potent xanthine oxidase (XOD) inhibitor by previous study. This study aimed to evaluate the hypouricemic effects of J99745 in experimental hyperuricemia mice, and explore the underlying mechanisms. Mice were orally administered 600 mg/kg xanthine once daily for 7 days and intraperitoneally injected 250 mg/kg oxonic acid on the 7th day to induce hyperuricemia. Meanwhile, J99745 (3, 10, and 30 mg/kg), allopurinol (20 mg/kg) or benzbromarone (20 mg/kg) were orally administered to mice for 7 days. On the 7th day, uric acid and creatinine in serum and urine, blood urea nitrogen (BUN), malondialdehyde (MDA) content and XOD activities in serum and liver were determined. Morphological changes in kidney were observed using hematoxylin and eosin (H&E) staining. Hepatic XOD, renal urate transporter 1 (URAT1), glucose transporter type 9 (GLUT9), organic anion transporter 1 (OAT1) and ATP-binding cassette transporter G2 (ABCG2) were detected by Western blot and real time polymerase chain reaction (PCR). The results showed that J99745 at doses of 10 and 30 mg/kg significantly reduced serum urate, and enhanced fractional excretion of uric acid (FEUA). H&E staining confirmed that J99745 provided greater nephroprotective effects than allopurinol and benzbromarone. Moreover, serum and hepatic XOD activities and renal URAT1 expression declined in J99745-treated hyperuricemia mice. In consistence with the ability to inhibit XOD, J99745 lowered serum MDA content in hyperuricemia mice. Our results suggest that J99745 exerts urate-lowering effect by inhibiting XOD activity and URAT1 expression, thus representing a promising candidate as an anti-hyperuricemia agent.
ABSTRACT
Objective@#To investigate the tumor microenvironment of immune tolerance induced by glioma stem cells (GSC).@*Methods@#Human GSC SU3 cells transfected with red fluorescent protein (SU3-RFP) gene were implanted into the brain, subcutis (armpit and foot), liver and abdominal cavity of transgenic green fluorescence protein (GFP) nude mice to establish RFP+ /GFP+ dual fluorescence solid tumor model. The re-cultured cells derived from implanted tumor tissues, SU3-RFP cells co-cultured with peritoneal fluid of transgenic GFP nude mice and malignant ascites of tumor-bearing mice were observed by fluorescence microscopy and real-time video image tracing to analyze the microenvironment of immune tolerance mediated by RFP+ /GFP+ implanted tumor.@*Results@#Dual fluorescence labeled frozen section showed that all of cells in the tumor microenvironment were GFP+ , while the pressed tissue-patch showed that the tumor blood vessels exhibited a RFP+ /GFP+ double-positioning yellow. In the GFP single fluorescence labeled tumor tissue, all of cells in the microenvironment were green, including tumor edge, necrotic foci and blood vessel. Among them, CD68+ , F4/80+ , CD11c+ , CD11b+ and CD80+ cells were observed. In the dual fluorescence labeled co-cultured cells, the phagocytosis and fusion between green host cells and red tumor cells were also observed, and these fusion cells might transfer to the malignant dendritic cells and macrophages.@*Conclusions@#The tumor microenvironment of immune tolerance induced by GSC is not affected by the tissue types of tumor-inoculated sites, and the immune tolerance mediated by inflammatory cells is associated with the inducible malignant transformation, which may be driven by cell fusion.

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.
