AIM:To investigate the therapeutic and preventive effects of paeoniflorin ( PF) on APP/PS1 mice, and to explore the possible mechanism. METHODS:Fifteen male 5-month-old APP/PS1 non-dominant mice were chosen as normal control group, 15 male 5-month-old APP/PS1 double transgenic mice were used as model group, and 15 male 5-month-old APP/PS1 double transgenic mice treated with 5 mg/kg PF by intraperitoneal injection were allocated in administation group. The learning and memory ability of the mice in each group was detected by Morris water maze. The apoptosis was assessed by TUNEL fluorescence staining. The protein expression of PI3K, Akt, p-PI3K, p-Akt, caspase-3, caspase-9, Bcl-2 and Bax in cerebral cortex and hippocampus was detected by Western Blot. The protein expression levels and distribution of caspase-3 and caspase-9 were detected by immunohistochemistry. RESULTS:(1) Compared with nor-mal control group, the learning and memory ability declined in APP/PS1 model group. Compared with APP/PS1 model group, PF obviously improve the ability of learning and memory in mice. (2) Compared with normal control group, the ap-optosis of nerve cells in APP/PS1 model group significantly increased and distributed in wider areas, while that in PF group was reduced (P<0.05). (3) Compared with APP/PS1 model group, PF could significantly lower pro-apoptotic factors, caspase-3, caspase-9 and Bax (P<0.05), and increase the expression of anti-apoptotic factors, p-PI3K, p-Akt and Bcl-2 (P<0.05). CONCLUSION:PF can up-regulate the expression of Bcl-2 and down-regulate the expression levels of caspase-9, caspase-3 and Bax via the activation of PI3K/Akt pathway, thereby inhibiting the nerve cell apoptosis and pro-tecting the nerve cells, so as to treat neurodegenerative diseases.

A in vitro platelet aggregation bioassay was developed for the quality control of XST capsules. The in vitro anti-platelet aggregation effect in rats was observed to detect the bioactivity of XST capsules. Panax notoginseng saponins and Xuesaitong lyophilizedpowder for injection were taken as standard control substances to determine the potency. According to the results, XST capsules showeda significant inhibitory effect on thrombin-induced platelet aggregation in a dose-dependent manner. The in vitro anti-platelet activity oflyophilized powder for injection was stabler than that of Panax notoginseng saponins, and so suitable to serve as a standard control substance. The biological potency of XST capsules compared with standard control substance was detected by using parallel line assay. According to the results, the established bioassay method had a good repeatability (RSD 2.92%). The sample test results could pass thereliability test(linear deviation P > 0.05, parallel deviation P > 0.05). This bioassay method could be used as one of the complementary quality control methods for XST capsules.

Objective To investigate the effect of lemon peel extracts(LPE) on the activity of lactate dehydrogenase and sucrase of Streptococcus mutans (Sm). Methods After serial dilution with trypticase soy broth (TSB) medium containing 2% glucose, LPE was used as the experimental group, and TSB without LPE as the control group. Sm was added to each group,which was then cultured for 6,18,24 and 48 hours in the anaerobic tank. The activity of lactate dehydrogenase (LDH) was measured with the method of oxidation of reduction coenzyme I and the pH value of the culture solution was also detected. The activity of the sucrose was determined with the method of coloration of 3,5-dinitrosalicylic acid. Results The activity of LDH, sucraae and the changes of solution pH were decreased with the increase of the concentration of LPE (P < 0. 01 ). The activity of LDH were declined from (0. 8025 ± 0. 0913 ) × 103 U/L to (0. 2099 ±0. 0283) × 103 U/L; the activity of sucrase were declined from ( -0. 0107 ±0. 0003) × 103 U/L to ( -0.0078 ±0.0002) × 103 U/L; the△pH were declined from(2.8067 ±0.0404) to (2.5033 ±0. 0416) (24 h results). The differences were significant between experimental groups and the control group (P < 0. 01 ), and there were also significant differences among experimental groups with different LPE concentration( P <0. 01 ). The inhibitory effect of acid generation and lactate dehydrogenas' activity of Sm were positively correlated ( P < 0. 01 ). Conclusions LPE can inhibit the activity of lactate dehydrogenase,sucrase and the acid production capacity of the Sm in a dose dependent manner. The inhibitory effects in logarithmic phase is stronger than that in other phases of growth cycle.

OBJECTIVETo evaluate the effectiveness of cerebral revascularization in the treatment of intractable aneurysms and to discuss the indications, surgical techniques, and the outcome of the revascularization.
METHODSDuring the recent 4-year period, 9 radical artery grafts were performed in patients with intractable or giant internal carotid artery (ICA) aneurysms. The indications for cerebral revascularization included parent vessel occlusion during the treatment of the intractable aneurysms with poor collateral circulation or the young patients. Modified techniques were taken to use the main trunk of superficial temporal artery (STA) as donor, while M3 branches near the bifurcation of the M2 segment of the middle cerebral artery (MCA) were chosen as the recipient arteries. STA-Radial artery (RA)-MCA bypass was followed by parent vessel occlusion via chronic cervical ICA ligation or balloon occlusion.
RESULTSPostoperative angiography demonstrated the patency of the grafts in eight cases. The procedure of the parent vessels occlusion was uneventful in these patients. Follow-up showed the patients were in excellent conditions after successful treatment of aneurysms. Significantly delayed filling of the graft was revealed in one patient, who could not tolerate balloon occlusion test and occlusion of parent artery failed.
CONCLUSIONSExtracranial-to-intracranial bypass followed by parent vessel occlusion is a safe and effective method to treat intractable ICA aneurysms. Radical artery as graft can offer high-flow revascularization with less complications. Combined surgical and endovascular treatment might be the future direction for the treatment of the difficult aneurysms.

Objective To compare the subjective satisfaction of the free radial forearm flap (FRFF) and anterolateral thigh flap (ALTF) of the donor site after surgical reconstruction for tongue cancer. Methods A total of 121 consecutive patients underwent FRFF or ALTF reconstruction after ablative surgery for untreated, primary tongue squamous cell carcinoma at Tianjin Stomatological Hospital and Peking University School and Hospital of Stomatology from August 2011 to October 2014 were enrolled in this study. The subjective satisfaction of the donor site, including sensibility, movement disabilities, cosmetics, social activities and general impacts on the quality of life (QOL), was assessed by a self-established donor site morbidity questionnaire from October 2016 to January 2017. Results Of the 121 patients, 34 died because of cancer or other diseases, 2 were excluded because of recurrence after reconstruction surgery, 11 lost to contact, and 74 (61.2%) completed the questionnaires finally, which included 39 patients in FRFF group and 35 patients in ALTF group. The scores for sensibility, cosmetics, general impacts on the QOL and composite score were significantly higher in ALTF group than those of FRFF group (P<0.05). No significant differences were found in the movement disabilities and social activities between the two groups (P > 0.05). Conclusion ALTF has the advantage of better results of donor site morbidity, less adverse effect on the general QOL, and higher subjective satisfaction.
