ObjectiveTo compare the efficacy of step-up and top-down infliximab therapy on patients with Crohn's disease (CD).MethodsA prospective and open-label study was performed by the First Affiliated Hospital of SUN Yat-sen University during September 2007 to December 2010.Active CD patients who were refractory to steroid/immunomodulator or who were steroid-dependent were enrolled into step-up group.Active CD patients who had no steroid or immunomodulator therapy before were enrolled into top-down group. All patients were intravenously infused with infliximab of 5 mg/kg body weight in an induction regimen of 3 doses at week 0,2 and 6,followed by maintenance dosing every 8 weeks beginning at week 14.The clinical and endoscopic follow up lasted 30 weeks.Clinical symptoms and mucosal healing status under endoscopy were evaluated by follow-up at week 10 and 30.Results Forty-one CD patients were enrolled,with 24 in step-up group and 17 in top-down group. There were significant differences in disease duration (P =0.006),combination therapy (P ＜ 0.001 ) and severity of disease ( P =0.011 ) in baseline between step-up and top-down groups.At week 10 and 30 during treatment,the clinical remission rates in step-up group were 45.8％ (11/24) and 58.3％ (14/24) respectively; the mucosal healing rates in step-up group were 33.3％ (8/24) and 54.2％ (13/24) respectively; the clinical remission rates in topdown group were 70.6％ ( 12/17)and 82.4％ (14/17) respectively; and the mucosal healing rates in topdown group were 35.3％ (6/17) and 52.9％ (9/17) respectively.No significant differences in clinical remission and mucosal healing rates at both week 10 and 30 were observed between the two groups.The prevalences of adverse events in step-up and top-down group were 41.7％ (10/24) and 29.4％ (5/17)respectively ( P =0.422).ConclusionBoth step-up and top-down infliximab therapy can induce remission in more than half of CD patients,while top-down therapy might be more benefitiary to symptom and endoscopic remission.

Objective To investigate the efficacy and safety of a novel biologies-infliximab in the treatment of patients with Crohn's disease (CD). Methods A prospective study was conducted in 10 patients with CD(8 with active refractory CD and 2 with severe lower gastrointestinal bleeding caused by CD). All patients were intravenously infused with infliximab of 5 mg/kg body weight in an induction regimen of 3 doses at week 0, 2 and 6, followed by maintenance dosing every 8 weeks beginning at week 14. The clinical and endoscopic efficacy of infliximab were evaluated by follow-up of 30 weeks. Results ① Five out of 8 patients with active CD had initial clinical response at week 2. Clinical remission was found in 4 patients at week 30, (3 of them in symptomatic remission without corticosteroids). ② Two patients with severe lower gastrointestinal bleeding caused by CD were in control of bleeding and absence of further recurrence by 30 weeks follow-up. ③ Endoscopy was performed in 6 patients at week 30 to evaluate the healing of mucosal ulceration. Four patients were evaluated for complete or almost mucosal healing. ④ Adverse events were seen in 7 out of 10 patients with infliximab treatment, among whom 2 cases had severe side effect including pneumonia in one and delayed hypersensitirity reaction in the other. Conclusion Infliximab has efficacy for the induction and maintenance of remission in part of patients with active CD. Some patients achieved mucosal healing with infliximab therapy and low incidence of serious adverse events.

Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0％(29/42) vs. 39.9％(89/223) and 57.1％(24/42) vs. 25.1％(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95％ CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

Objective To investigate the relationship between different topographic locations and neurological deteriorations (ND) in patients with acute new isolated pontine infarction.Methods One hundred sixty-eight patients with acute new isolated pontine infarction during arch 2012 to March 2016 were identified by diffusion weighted imaging (DWI) for retrospective review.Patients were divided into two groups according to their clinical symptoms:patients with ND and patients without ND.According to neuroimaging of DWI,the topographic location of pontine infarction was divided into three types:The upper,middle,and lower ones,and the correlations of ND with risk factors,laboratory examination results,clinical manifestations and different topographic locations were explored by statistical tests.Results Of 168 patients,26.8％ (45/168) were diagnosed with ND,and 73.2％ (123/168) were diagnosed without ND.Univariate analysis showed that there were differences in female ratio [62.2％ (28/45) vs 41.5％ (51/ 123)],smoking ratio [13.3％ (6/45) vs 26.0％ (32/123)],mean length of hospital stay [(22.83 ± 7.12)d vs (19.31 ± 7.65)d],ratio of worse short-term clinical outcomes [77.8％ (35/45) vs 33.3％ (41/123)],and ratio of lower pontine infarction [55.6％ (25/45) vs 26.0％ (32/123)] between two groups (P ＜ 0.05).Logistic regression analysis showed that lower pontine infarction was the independent risk factor of ND (OR =1.953,95％ CI:1.092-3.535,P =0.029).Conclusions Topographic location of lower pons lesions may be reliable predictor of ND in acute new isolated pontine infarction.

Objective: To explore the cognitive level and the mental status of the patients suffering from perimenopausal syndrome in Shanghai, and to identify the traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome. Methods: The cognitive level of the perimenopausal women was evaluated by using general living problem questionnaire. The mental status of the perimenopausal women was evaluated by using self-rating depressive scale. The traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome was identified by using traditional Chinese medical symptoms questionnaire. Results: A total of 634 perimenopausal women finished the investigation. There were 74.76% (474/634) patients who knew little about the perimenopausal syndrome; 77.29% (490/634) patients had a depressive tendency; 8.36% (53/634) patients had depressive disorder. There were 72.40% (459/634) patients who had the symptoms such as susceptibility to anger and restlessness, restless sleep at night, thirst with dry throat and bitter taste, and all these symptoms could be classified into hyperactivity of heart and liver fire syndrome. Conclusion: Patients suffering from perimenopausal syndrome know little about this disease and mostly have depressive tendency, and the major traditional Chinese medicine syndrome pattern is hyperactivity of heart and liver fire based on the chief clinical manifestations of the patients.

Three-dimensionally controlled cell-assembly technique makes fabricating tissues and organs in vitro to be possible. However, for real tissues and organs with complex structure and various cells, fabricating tissues and organs in vitro need a technique that could assemble and locate multi cells and materials precisely in the space. Facing the needs of multi-cell assembly, we designed a mixer nozzle and the matching pulse switching circuit which based on the single-nozzle cell assembly system, and developed a multi-cell-assembly system. We also carried out some assembly experiments with this system using materials that were similar to the multi-component extracellular matrix materials. The results demonstrated that the system could assemble various cells and materials into three-dimensional inhomogeneous structures precisely.

Serious femoral damages are a common human bone disease. Rebuilding the femur and studying its mechanical properties are a continuous medical research topic, but traditional femoral prosthesis often cause some problems such as prosthesis loosening. In this work, we selected a healthy male, took his femur scanning by CT, and rebuilt high-precision femur prototypes by Mimics10.0 software, then chose the material having good biocompatibility and biodegradable, utilizing low-temperature deposition manufacturing (LDM) technology for the femoral manufacturing. This approach, fabricating the femur via LDM technology, laid a foundation for the later research on the femoral implantation in the human body.

Since there is a clinical need for the tissue-engineered vascular graft (TEVG), fabricating the vascular scaffold individually appears to be necessary. In this work, we have developed the traditional tubular scaffold and branch vascular scaffold utilizing low-temperature deposition manufacturing (LDM) technology. Then different tubular scaffolds were fabricated by changing the processing parameters, and the morphological properties of the scaffolds were assessed. The scaffolds reproduced the structure of 3D vascular model accurately. Wall thickness of the scaffold increased with the increase of velocity ratio (V(L)/V(s)) and nozzle temperature, and both the micropore size and wall roughness were positively correlated with the nozzle temperature. However, the porosity was barely affected by the nozzle temperature. This approach, fabricating vascular scaffold with special structure and appearance features via LDM technology, is potential for the individual fabrication of vascular scaffold.
