ABSTRACT

Objective:To investigate the clinical effect of "ladder reduction method" in the treatment of iliac fracture combined anterior dislocation of sacroiliac joint.Methods:The retrospective analysis was performed on 10 cases of iliac fracture combined anterior sacroiliac joint dislocation admitted to the Affiliated Hospital of Yunnan University from February 2010 to January 2022, among which 5 cases were males and 5 cases were females, aged ranging from 22 to 52 years, with an average age of 38.8 years. All patients were injured in car accidents including 5 cases of C1.2, 3 cases of C2, and 2 cases of C3 fractures according to Tile classification. All patients were treated with the "ladder reduction method" with plate and screw fixation. In the first step, 1-2 Schanz pins were inserted into the iliac crest to control the ilium, and the Schanz pins were appropriately pulled laterally; in the second step, the periosteal stripper was used to pry the reduction between the sacrum and ilium; in the third step, for the patients who still could not be reduced, a 2.5 mm diameter Kirschner wire was placed on the sacrum close to the iliac crest, and a periosteal stripper was inserted between the sacrum and iliac crest, with its tip against the Kirkner wire, and the iliac crest as the fulcrum for pry pulling to separate the two. In the fourth step, the pry was maintained, and then another 2.5 mm diameter Kirschner wire was placed on the sacrum close to the internal margin of the iliac bone. The periosteal stripper was continued to pry between the sacrum and the iliac bone, and the operation was repeated. At the same time, the anterior dislocation of the sacroiliac joint was reduced with traction of the lower limb. Postoperatively, the quality of reduction was evaluated by the Matta score, and the degree of functional recovery after pelvic fracture was evaluated by the Majeed score.Results:Four patients completed the reduction through the first and second steps, and 6 cases of refractory sacroiliac joint anterior dislocation were successfully reduced through the first to fourth steps. The fracture reduction time of 6 patients with refractory anterior sacroiliac joint dislocation was 39.67±3.09 min (range, 35-44 min), with intraoperative blood loss of 300.00±141.42 ml (range, 150-600 ml); in the other 4 cases, the fracture reduction time was 36.75±4.38 min (range, 30-42 min), and the intraoperative blood loss was 225.00±44.30 ml (range, 200-300 ml). All 10 patients were followed up for 12.9±3.7 months (range, 9-20 months). The anterior and posterior pelvic ring fractures were healed in all patients, and the fracture healing time was 12.77±1.62 weeks (range, 10.71-15.28 weeks). At the last follow-up, Matta evaluation was excellent in 5 cases, good in 1 case, and excellent in the other 4 cases. The Majeed scores of 6 cases were 86.50±6.08 points (range, 74-92 points), of which 5 cases were excellent and 1 case was good. The other 4 cases were 81.5±9.39 scores (range, 71-94), of which 2 were excellent and 2 were good.Conclusion:The "ladder reduction method" is a safe, effective and easy-to-operate method for the treatment of iliac fracture combined anterior dislocation of the sacroiliac joint, especially for refractory anterior dislocation of the sacroiliac joint, which can still obtain satisfactory curative effects.

ABSTRACT

ABSTRACT Introduction: Aerobics is a recreational, ornamental, rhythmic, and expressive sport. It is widely used in physical education in colleges and universities because it is also believed that this sport benefits the cardiopulmonary function and the body composition of the practitioners. Objective: Study the influences of aerobic gymnastics on body composition and cardiopulmonary function in its practitioners. Methods: 40 college students volunteered for the research sample. The living conditions and learning level of the subjects were the same. The students were divided into two groups for research. There was no significant difference between the groups comparing the volunteers' age, height, and weight. The high-load group performed exercises with a maximum heart rate of 220, while the low-load group performed the same protocol under a maximum heart rate of 195 beats per minute. The intervention took place over 40 and 60 minutes of exercise, respectively, for eight weeks. The POLAR monitor was used to check the kinematic performance of the athletes. The data were processed statistically. Results: Aerobic gymnastics influenced the body composition of college students with significant differences in bust circumference, waist, hip, thigh, and skinfold thickness (P<0.05). The athletes' heart rate, pulmonary ventilation, and diastolic pressure increased significantly after aerobic gymnastics. The study showed that the resting heart rate of the volunteers decreased significantly after exercise, and their lung function returned to normal (P<0.05). Conclusion: Aerobic exercise can improve the body composition, physiology, and cardiopulmonary function of its practitioners, and its greater encouragement in colleges and universities is recommended.

ABSTRACT

Objective:To investigate the efficacy and safety of lenalidomide combined with bortezomib and dexamethasone (RVD) in patients with newly diagnosed multiple myeloma (NDMM).Methods:A total of 100 consecutive NDMM patients treated with RVD from August 2016 to September 2020 at Peking University People′s Hospital were retrospectively analyzed, including response, drug toxicity, follow-up and survival, and subgroup analysis.Results:The median follow-up time was 19.5 (2.0-57.0) months. For patients undergoing autologous stem cell transplantation (ASCT) after RVD regimen, the objective response rate (ORR)/complete response+stringent complete response (CR+sCR)/≥very good partial response (VGPR) rates were 100%, 73.3% (33/45), 95.6% (43/45) respectively. For 54 patients not receiving transplantation, the ORR/CR+sCR/≥VGPR rates were 79.6% (43/54), 18.5% (10/54), 51.9% (28/54) respectively. As to the survival analysis, 2-year progression free survival (PFS) rates were 84.5% and 70.9% in transplant and non-transplant patients respectively ( P=0.102). Two-year overall survival (OS) rates were 100% and 80.8% in transplant and non-transplant patients respectively ( P=0.003). The common hematologic adverse events (AEs) were thrombocytopenia (33%) and neutropenia (25%). Abnormal liver function (43%) and peripheral neuropathy (24%) were recognized more as non-hematologic AEs. Conclusion:RVD as front-line regimen has high efficient response rate and acceptable safety in Chinese NDMM patients.

ABSTRACT

Objective:To analyze the efficacy and safety of Daratumumab for the treatment of primary AL light chain systemic amyloidosis.Methods:Twenty one patients who were diagnosed as primary AL light chain systemic amyloidosis and treated with Daratumumab from 7 centers were retrospectively analyzed. Daratumumab was administrated as first line therapy in seven patients and 14 patients with relapsed settings. Hematological response, safety and survival were analyzed.Results:All 7 patients achieved very good partial response (VGPR) or better with first-line application of daratumumab. Three patients died, and the other four achieved organ remission. Among 14 relapsed patients, 2 patients had a difference of free light chain (dFLC) less than 20 mg/L before treatment, and 9 with a dFLC of more than 50 mg/L. All patients reached partial response (PR) or better, including 4 patients with complete response (CR), 3 with VGPR and 2 with PR. The response rate was 100% in 3 patients with dFLC 20-50 mg/L at baseline. The organ remission rate was 50% in patients with heart involvement and 58.3% in patients with kidney impairment. The overall median follow-up period was 5.3 months, and 11 months in surviving patients. One patient died of severe infection and disseminated intravascular coagulation (DIC) with stable amyloidosis. One patient switched to other regimens because dFLC elevated but did not fulfill progressive disease after 2 year application. As to safety, no grade 3/4 infusion reaction developed, and grade 1 infusion reaction occurred in 3 cases during the first infusion. Lymphocytopenia was seen in 75% patients including grade 3 or more in 30% patients.Conclusion:Daratumumab is effective to eliminate serum free light chain in both newly diagnosed and relapsed patients with systemic amyloidosis.

ABSTRACT

Objective:To investigate the expression changes at the transcriptional level in normal lung tissues of mice after exposure to heavy ion radiation for different durations at different doses, aiming to provide evidence for exploring sensitive genes of heavy ion radiation, heavy ion radiation effect and the damage mechanism.Methods:Experiments on the temporal kinetics: the whole thorax of mice was irradiated with 14.5Gy carbon-ions and the total RNA of lung tissue was extracted at 3days, 7days, 3 weeks and 24 weeks. In dose-dependent experiment, the total RNA of lung tissue was extracted at 1 week after irradiated with a growing thoracic dose of 0, 7.5, 10.5, 12.5, 14.5, 17.5 and 20Gy. Protein-to-protein interaction (PPI) analysis and gene-ontology biological process enrichment analysis were performed on significant differentially expressed genes (DEGs).Results:A clearly differential expression patterns were observed at 3-day (acute stage), 1-week (subacute stage), 3-week (inflammatory stage) and 24-week (fibrosis stage) following 14.5Gy carbon-ions irradiation. Among those, the 3-day time point was found to be the mostly different from the other time points, whereas the 7-day time point had the highest uniformity with the other time points. Cellular apoptosis was the main type of cell death in normal lung tissues following carbon-ions exposure. The interactive genes of Phlda3, GDF15, Mgmt and Bax were identified as the radiosensitive genes, and Phlda3 was the center ( R=0.76, P<0.001). Conclusion:The findings in this study provide transcriptional insights into the biological mechanism underlying normal lung tissue toxicity induced by carbon-ions.

ABSTRACT

This paper was to investigate the effect of Huanglian Jiedu Decoction(HLJD) on ulcerative colitis(UC) in mice, and determine the effective components in plasma, and virtually screen its therapeutic target, and predict its mechanism. Sixty Balb/c mice were randomly divided into blank group, model group, mesalazine treatment group(0.3 g·kg~(-1)), and HLJD treatment groups(24.66, 12.33, 6.17 g·kg~(-1)). Excepted for the blank group, all the mice in HLJD and mesalazine treatment groups were gavage administration. All mice freely drank 2.5% DSS solution for seven days to induce UC. The disease activity index(DAI) was detected each day. At the end of the experiment, HE staining was used to observe the pathological changes in colon. The content of IL-1β, IL-6 and TNF-α in colon were determined by ELISA. The effective components in plasma were determined by UPLC-Q-TOF-MS. The reverse docking in PharmMapper was used to screen the component targets. The disease targets of UC were collected by searching TTD, OMIM and GeneCards databases. The intersection of the component targets and disease targets was selected as the therapeutic targets. Then the therapeutic targets were imported into the STRING for GO and KEGG enrichment analysis. Discovery Studio was used to simulate the docking between the components and the targets. RESULTS:: showed that the DAI in the model group increased significantly(P<0.05), and the number of inflammatory cells and infiltration degree increased significantly compared with the blank group. The DAI in HLJD treatment group was significantly reduced(P<0.05), and the number and infiltration degree of inflammatory cells were reduced compared with the model group. The ELISA results showed that the levels of IL-1β, IL-6 and TNF-α were increased significantly in the model group(P<0.01) compared with the blank group, and significantly down regulated in the HLJD treatment group(P<0.05) compared with the model group. After UPLC-Q-TOF-MS analyse, ten components were identified. The network pharmacology analysis showed that the action targets were significantly enriched in 129 of biological processes, such as response to organic substance, chemical and oxygen-containing compound, etc., as well as 16 of signal pathways, such as IL-17, TNF and hepatitis B signal pathways, were enriched too. The results of molecular docking showed that limonin, palmatine and berberine could bind to CASP3 and MMP9 by hydrogen bond. In conclusion, HLJD could alleviate the colonic mucosal inflammatory infiltration and mucosal damage in UC mice. The mechanism may be related to the anti-inflammatory effect on UC mice by reducing the levels of IL-1β, IL-6 and TNF-α in colon through limonin, palmatine and berberine regulating IL-17 signal pathway and TNF signal pathway via CASP3 and MMP9 meditated.

ABSTRACT

Objective:To investigate the clinical manifestation, diagnosis and prognosis of heavy- and light-amyloidosis (AHL).Methods:The clinical data of two patients with AHL in Peking University People's Hospital and 21 cases of reported literature were reviewed to clarify the clinical and prognostic characteristics of AHL.Results:Compared with light-amyloidosis, most AHL patients were male, with high positive rate of blood and urine immunofixation electrophoresis and complete immunoglobulin. The manifestations of the kidneys were proteinuria, mainly composed of albumin, nephrotic syndrome and microscopic haematuria. The pathology of renal biopsy showed that Congo red staining positive substances were deposited in many sites (mesangial area, capillary wall, arteriole and renal interstitium), and immunofluorescence showed that monoclonal heavy chain with light chain (the type was consistent with the hematuria M protein) were clumpy deposition, which was consistent with amyloid deposition site. Heart involvement was rare, and the proportion of plasma cells in bone marrow was high.Conclusion:AHL is rare and its clinical manifestations of AHL are different from those of light-amyloidosis. The prognosis needs to be further observed.

ABSTRACT

Objective:To analyze the immunophenotype and cytogenetic characteristics of primary plasma cell leukemia (pPCL), and to evaluate the efficacy of bortezomib and hematopoietic stem cell transplantation as main treatment.Methods:A retrospective cohort study was conducted including 42 pPCL patients admitted to Peking University People′s Hospital from January 1998 to March 2019. All patients were followed up until December 31, 2019. The immunophenotype and cytogenetic characteristics were compared with historical data of multiple myeloma (MM). Thirty-nine patients were divided into bortezomib-based group (29 cases) and non-bortezomib group (10 cases). All patients were also divided into hematopoietic stem cell transplantation (HSCT) group (15 cases) and non-HSCT group (24 cases).Chi-square test was used for efficacy comparison, and Kaplan-Meier method was used for univariate prognostic analysis. Cox proportional hazards model was used for multi-variant analysis.Results:pPCL accounted for 2.6% of the total patients with plasma cell diseases during the same period. There were 22 males and 20 females, with a median age of 50 (30—77) years old at diagnosis. In immunophenotype analysis, tumor cells in pPCL patients also expressed CD38, CD138, CD45, which was similar as patients with MM. However the expression of CXCR4 were more frequently seen in pPCL(73.1% vs. 34.7%, P= 0.000), while intensity of CD9 and CD200 was lower (40.7% vs. 62.5%, P =0.028, 33.3% vs. 58.0%, P=0.021).Overall response rate of bortezomib-based therapy was superior to non-bortezomib therapy (69.0% vs.50.0%). The median survival was 18.2 (0.2—95.7)months, and the 1-and 2-year survival rates were 61.9% and 37.4%, respectively. Multivariate prognostic analysis suggested that age ( P= 0.027) and efficacy( P= 0.035)were significantly correlated with survival.HSCT resulted in superior survival compared with chemotherapy alone(26.8 vs. 8.1 months, P=0.021). Conclusions:Immunophenotypes and cytogenetic abnormalities in patients with pPCL are different from those with multiple myeloma. Bortezomib based regimens improve response rate and survival of pPCL. Hematopoietic stem cell transplantation also predicts survival benefits.

ABSTRACT

Objective:To investigate the efficacy and safety of daratumumab in relapsed and refractory multiple myeloma (RRMM).Methods:The efficacy and adverse events (AEs) of daratumumab based regimens were retrospectively analyzed in 37 patients with RRMM from Peking University People′s Hospital, Beijing Hospital and Fu Xing Hospital affiliated to Capital Medical University in China. The deadline for inclusion was December, 2019.Results:Among the 37 patients, 35 patients were available for response evaluation. The overall response rate (ORR) was 68.6%, which was better in patients receiving 16 mg/kg daratumumab than in those with fixed doses of 800 mg daratumumab [ORR: 78.3%(18/23) vs. 40.0%(4/10)]. The percentage of infusion related reactions of daratumumab was 27.0%(10/37). The most common hematological AEs were lymphocytopenia and thrombocytopenia, with the incidences of grade 3 or more severe 59.5%(22/37) and 43.2%(16/37) respectively. Pulmonary infections(37.8%, 14/37) were the most common non-hematological AEs. One patient with positive hepatitis B surface antigen (HBsAg) and two patients dependent on dialysis were safely treated with daratumumab.Conclusion:Daratumumab is highly effective in relapsed and refractory multiple myeloma. Adverse reactions are mild and well tolerable.

ABSTRACT

Objective To investigate the radiation induced pulmonary fibrosis with a dose-response mouse model, based on the CT image changes of pulmonary fibrosis.Methods Female C57BL6 mice aged 8-10 weeks were randomly divided into 20 Gy or escalated doses of X-ray whole thoracic irradiation ( WTI) groups. CT scan was performed at different time points before and after radiation. The average lung density and lung volume changes were obtained by three-dimensional segmentation algorithm. After gene chip and pathological validation, the parameters of CT scan were subject to the establishment of logistic regression model. Results At the endpoint of 24 weeks post-irradiation, the lung density in the 20 Gy irradiation group was (-289.81± 12.06) HU, significantly increased compared with (-377.97± 6.24) HU in the control group ( P<0.001) . The lung volume was ( 0.66±0.01) cm3 in the control group, significantly larger than ( 0.44±0.03) cm3 in the irradiated mice ( P<0.001) . The results of quantitative imaging analysis were in accordance with the findings of HE and Mason staining, which were positively correlated with the fibrosis-related biomarkers at the transcriptional level ( all R2=0.75, all P<0.001) . The ED50 for increased lung density was found to be ( 13.64± 0.14) Gy ( R2=0.99, P<0.001) and ( 16.17± 4.36) Gy ( R2=0.89, P<0.001) for decreased lung volume according to the logistic regression model. Conclusions Quantitative CT measurement of lung density and volume are reliable imaging parameters to evaluate the degree of radiation-induced pulmonary fibrosis in mouse models. The dose-response mouse models with pulmonary fibrosis changes can provide experimental basis for comparative analysis of high-dose hypofractioned irradiation-and half-lung irradiation-induced pulmonary fibrosis.

ABSTRACT

Objective: To analyze the treatment effect of the number of bortezomib, cyclophosphamide, and dexamethasone (BCD) chemotherapy courses for newly diagnosed multiple myeloma. Methods: We retrospectively analyzed data of patients with newly diagnosed multiple myeloma from January 2014 to July 2016 in Peking University People's Hospital. All 70 patients received two or more courses of BCD chemotherapy. Patients with extramedullary disease or amyloidosis were excluded. Patients completed their follow-up, and the treatment effects were studied in those who only received two, four, and six chemotherapy courses. Results: Among the 70 patients, the ratio of male to female was 36 :34, the median age of disease onset was 58.4 y (range: 33-81 y), and the number of patients with ISS stagesⅠ,Ⅱ, and Ⅲ was 16, 18, and 36, respectively. The number of patients who received two, four, and six chemotherapy courses was 14, 20, and 36, respectively. The percentages of complete remission, equal or more than very good partial remission, equal or more than partial remission for patients who received two courses were 14.28%, 42.86%, and 71.42%, those for four courses were 30.00%, 60.00%, 80.00%, and those for six courses were 38.89%, 75.00%, 83.33%, respectively. During the median 15.37 (range: 2-32) months follow up, the estimated progression free survival (PFS) was 21.96 months (95% CI: 19.26-24.70). No statistically significant difference for PFS was observed among the three groups (P=0.700). Conclusions: For the BCD chemotherapy regimen, the maximum therapeutic effect occurred after four or more courses. As the number of induction courses after four chemotherapies increased, the depth of disease relief increased but overall remission did not show substantial improvement. Therefore, four or more BCD chemotherapies can be used for the first line of induction therapy.

ABSTRACT

<p><b>BACKGROUND</b>Aspirin is widely used for the prevention of cardiovascular and cerebrovascular diseases for the past few years. However, much attention has been paid to the adverse effects associated with aspirin such as gastrointestinal bleeding. How to weigh the benefits and hazards? The current study aimed to assess the feasibility of a cardiovascular/gastrointestinal risk calculator, AsaRiskCalculator, in predicting gastrointestinal events in Chinese patients with myocardial infarction (MI), determining unique risk factor(s) for gastrointestinal events to be considered in the calculator.</p><p><b>METHODS</b>The MI patients who visited Shapingba District People's Hospital between January 2012 and January 2016 were retrospectively reviewed. Based on gastroscopic data, the patients were divided into two groups: gastrointestinal and nongastrointestinal groups. Demographic and clinical data of the patients were then retrieved for statistical analysis. Univariate and multiple logistic regression analyses were used to identify independent risk factors for gastrointestinal events. The receiver operating characteristic (ROC) curves were used to assess the predictive value of AsaRiskCalculator for gastrointestinal events.</p><p><b>RESULTS</b>A total of 400 MI patients meeting the eligibility criteria were analyzed, including 94 and 306 in the gastrointestinal and nongastrointestinal groups, respectively. The data showed that age, male gender, predicted gastrointestinal events, and Helicobacter pylori (HP) infection were positively correlated with gastrointestinal events. In multiple logistic regression analysis, predicted gastrointestinal events and HP infection were identified as risk factors for actual gastrointestinal events. HP infection was highly predictive in Chinese patients; the ROC curve indicated an area under the curve of 0.822 (95% confidence interval: 0.774-0.870). The best diagnostic cutoff point of predicted gastrointestinal events was 68.0‰, yielding sensitivity and specificity of 60.6% and 93.1%, respectively, for predicting gastrointestinal events in Chinese patients with MI.</p><p><b>CONCLUSIONS</b>AsaRiskCalculator had a predictive value for gastrointestinal events in Chinese patients with MI. HP infection seemed to be an independent risk factor for gastrointestinal events caused by long-term aspirin treatment in Chinese patients with MI, and it should be included in the risk calculator adapted for Chinese patients.</p>

ABSTRACT

Objective Bortezomib plus dexamethasone (BD) and bortezomib,epirubicin plus dexamethasone (PAD) are both front-line regimens of multiple myeloma.This study aimed to assess the efficacy and safety of BD versus PAD regimens in multiple myeloma.Methods All 208 patients with newly diagnosed multiple myeloma using either BD or PAD front-line regimens were enrolled between November 2006 and July 2014.Front-line chemotherapy regimens were 2-7 cycles.Response rates,overall survival,progression-free survival,and adverse effects were retrospectively analyzed.Results (1) In PAD group,the overall response rate was 82.9% [complete response(CR) 28.6%,very good partial response(VGPR) 12.9%],which was similar as that in BD group [70.3% (CR 26.8%,VGPR 5.1%),P =0.049].The estimated median progression-free survival was 34.0 months in PAD group versus 25.0 months in BD group (P =0.010).(2) The triplet regimen has a higher accumulated response rate along with chemotherapy cycles,but it didn't show any difference with the doublet regimen.(3) In elderly patients (> 65 years old),the overall response rates in two groups had no significant difference (P =0.769),while in patients ≤65 years old,PAD regimen were more effective than BD regimen (P =0.037).(4) Grade 3 and 4 adverse events were recorded with a higher number of patients in the PAD group than those in the BD group.Conclusions Compared with BD regimen,PAD regimen improves the initial response rates,especially deep responses,as well as progression-free survival in patients with newly diagnosed multiple myeloma.However,more severe toxicities are accordingly higher.In elderly patients,overall response rate,estimated median progression-free survival,and median overall survival are all comparable in both regimens.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical features and prognosis of acute leukemia patients with the mixed lineage leukemia(MLL)gene rearrangements AF10 positive.</p><p><b>METHODS</b>6 cases with MLL-AF10 positive were analyzed retrospectively, related literatures were reviewed to clarify MLL-AF10 patients'clinical features and prognosis.</p><p><b>RESULTS</b>The median age of 6 cases was 19.5 years old, 5 patients with fever onset, the onset white blood cells of 4 patients were less than 10×10⁹/L. 5 cases were as M₅ and 1 case M₄ according to FAB classification, the level of fusion gene(RQ-PCR)was 0.23%-22.60% when diagnosed, 4 cases had concomitant WT1 gene mutation, flow cytometry disclosed myeloid phenotype. Of 5 evaluated patients achieved the first complete remission after conventional chemotherapy, 2 cases of complex karyotype died, one case died of sepsis in induction, another died from failing of transplantation. 4 out of 5 transplant recipients gained long term survival.</p><p><b>CONCLUSION</b>The MLL-AF10 positive patients were mostly young men, the majority FAB classification was M5 or M4, often onset with fever, low white blood cells and low level of fusion gene, usually associated with WT1 mutation. Conventional chemotherapy produced a high response rate, but easy to relapse, while the complex karyotype had a poor prognosis, allo-HSCT may have the potential to improve the prognosis of MLL-AF10 positive patients.</p>

ABSTRACT

Objective To identify the genotype of the APP/tau/PS1 triple transgenic Alzheimer's disease (AD) mice,and investigate the pathological changes of tau protein in the pathogenic process.Methods Using specific primers of PS1,APP,tau gene,the genotypes of the triple transgenic AD mice were identified.Expression of tau protein in hippocampal tissue of mouse model aged 2,4,8 month was detected by immunohistochemistry.The expression of tau and its hyperphosphorylation in different sites in the hippocampal tissue and different month old mice was detected by Western blotting.Results PCR amplification fragment of 960 bp,530 bp and 400 bp of transgenic mouse genome were the expected size of APP,PS1,tau,respectively.Expression of tau in hippocampal CA3 region was increased obviously in the 8 month old mice.Compared with the normal wild-type mice,the expressions of tau and phosphorylation of pS262,pS404 and pS202 were increased significantly in hippocampus tissue of the transgenic mice (P<0.01).Expression of tau were significantly higher in 8-and 12-monthsold mice than in 2 months-old mice (P < 0.01).Phosphorylation level of pS404 and Ps202 was significantly increased since 2-months-old in transgenic mouse compared to the wild type mouse (P<0.01),and in 8-monthold mice,there was also a significant increase as compared to that in 2 month-old mice (P<0.01).As to the phosphorylation level of pSs262,the significant increase did not appear until 12 months old in transgenic mouse as compared to the wild type mouse (P<0.01).Conclusions The triple transgenic mice can stably express the APP/tau/PS1 gene.The transgenic animals can be a useful model with the pathological features of tau of AD.The phosphorylation level of tau in different site increases in different time,which will provide useful research reference in Alzheimer's disease pathology and medication research.
