Objective To study the influence of Noradrenergic systems in Lateral Hypothalamus Area (LHA) on small intestine moving. Methods The effect of noradrenalin、noradrenalin+phentolamine、noradrenalin+propolol、phentolamine on small intestines electro-activity of rats was detected by external alimentary canal electrodes and central nervous system stereo-configuration technology. Results After injecting 2 g/L noradrenaline (NE) the cyclic period of MMC extended, the ratio of the active time to the cyclic period and the number of the fast wave within the active time per minute reduced. NE inhibited the electro-activity of small intestine of rats, and the average effective time was (36.86?7.39)min. Hence injecting 5 g/L PE alone to LHA raised the ratio of the MMC active time to the cyclic period. Phentolamine presented a slight excitability on the electro-activity of small intestine of rats. Conclusion The NE in LHA showed the inhibitive myoelectric activity on small intestines, and this effect was introduced through a acceptor,The reacceptor in LHA may function in the inhibition of the electro-activity in small intestines.

Objective To investigate the guidance value of TOI classification in treating traumatic T-type atlantoaxial dislocation (ADD).Methods A retrospective case series study was made on 32 cases of traumatic TOI T-type ADD treated between January 2012 and December 2015.There were 19 males and 13 females,aged (38.4 ± 14.7) years.Fifteen cases of T1-type underwent external fixation or internal fixation without fusion,while 17 cases of T2-type underwent internal fixation with fusion.Symon-Lavender clinical standard,Japanese orthopedic association score (JOA),visual analogue scale (VAS),atlas-dens interval (ADI) and space available for the cord (SAC) were used to evaluate the therapeutic effect.Results Patients were followed up for 6-54 months (mean,32.4 months).At final follow-up,ADI was decreased to (2.3 ± 1.4) mm from preoperative (5.6 ± 1.6) mm,but SAC was increased to (15.4 ± 1.9) mm from preoperative (12.0 ± 2.9) mm(P ＜ 0.01).At final follow-up,cervical axial rotation range of motion was 102°-154° in T1-type cases and 57°-93° in T2-type cases.Range of motion for atlantoaxial joint was preserved in T1-type cases,but lost in T2-type cases.According to the Symon-Lavender clinical standard,there were 14 cases of mild disability,nine moderate disability,eight severe disability and one extremely severe disability before operation;there were 21 cases of mild disability,nine moderate disability and two severe disability at last follow-up.Significant difference was observed in the grades according to the Symon-Lavender clinical standard before operation and at last follow-up (P ＜0.05).At last follow-up,JOA score was increased to (14.6 ± 2.9) points from preoperative (9.9± 3.2) points,and VAS was decreased to (2.7 ± 1.3)points from preoperative (6.0 ± 1.6)points (P ＜ 0.01).Conclusions By using TOI classification,reconstruction of stability and improved neurological function can be achieved in treatment of traumatic T-type atlantoaxial dislocation.Non-fusion treatment of T1-type atlantoaxial dislocation can preserve range of motion for atlantoaxial joint.

Objective To explore the bone marrow pathology ,diagnosis and differential diagnosis of Waldenstrom macroglobulinemia(WM). Methods 19 WM patients was examined by bone marrow aspiration (BMA) and bone marrow biopsy (BMB) for morphology. Flow cytometry (FCM) and immunohistochemistry (IHC) for immunophenotyping. Results Plasmacytoid lymphocytes were identified in 11 BMA. All of 19 BMB were involved by lymphoma cells. 17 cases showed a predominance of small lymphocytes and 2 of plasmacytoid lymphocytes. Typically plasmacytoid lymphocytes were not seen in 4 cases. Patterns of bone marrow involvement were as follow: diffuse (12 cases), nodular (4 cases), interstitial (3 cases). Immunophenotypically, FCM showed all cases were CD_(19)~+, CD_(20)~+, CD_(22)~+, CD_5~- and CD_(10)~-. IHC revealed small lymphocytes and plasmacytoid lymphocytes were Pax5~+ CD_(20)~+ and plasma cells were CD_(38) CD_(138)~+ CD_(20)~- Pax5~-. Conclusion Small lymphocytes proliferation with plasmacytic differentiation is the typical bone marrow pathologic features of WM. IHC is benefit for identifying lymphocytes and plasma cells components. The Combination of morphology, FCM and IHC is contributive to the diagnosis and differentiation of WM.

Objective:To investigate the association of Subclinical Carotid AtheroSclerosis (SCAS) and prediabetes or Diabetes Mellitus (DM)in the healthy people.Methods:From September 2018 to June 2019, participants who underwent physical examination in the Health Management Center of Beijing Tiantan Hospitial were enrolled consecutively. The baseline characters were collected prospectively. Carotid Ultrasound was evaluated by radiologists according to the standard operating protocol. Univariable analysis and multivariable logistic analysis were used to estimate the association of prediabetes or DM with SCAS.Results:Totally 401 participants were eligible and enrolled. The mean age was (52.2±10.4) years and 43.7% (252/401) of them were females. The prevalence of DM and SCAS were 16.4% (66/401) and 48.9% (196/401) respectively. In the univariate analysis, elder age (≥60 years old) ( OR=5.93, 95% CI: 3.86-9.09, P<0.001), hypertension ( OR=2.76, 95% CI: 1.84-4.15, P<0.01), prediabetes( OR=1.67, 95% CI: 1.08-2.58, P<0.05) and DM ( OR=3.60, 95% CI: 1.97-6.58, P<0.01), cigarettes smoking ( OR=2.64, 95% CI: 1.82-3.81, P<0.001), lower HDLlevel<1.04 mmol/L ( OR=1.58, 95% CI: 1.04-2.42, P<0.001) and hyperhomocysteinemia (≥15 μmol/L)( OR=1.69, 95% CI: 1.17-4.04, P<0.01) were associated with higher prevalence of SCAS. On the contrary, female sex ( OR=0.53, 95% CI: 0.39-0.74, P<0.001) was associated with lower prevalence of SCAS. In the multivariable logistic analysis, elder age(≥60 years old) ( OR=6.04, 95% CI: 3.13-11.7, P<0.01), hypertension ( OR=2.14, 95% CI: 1.13-3.87, P<0.05), cigarettes smoking ( OR=2.19, 95% CI: 1.21-3.98, P<0.05) and DM ( OR=2.32, 95% CI: 1.16-4.67, P<0.05) were associated with SCAS independently. The association between prediabetes and SCAS was not statistically significant. Conclusions:DM is independently associated with SCAS in neurological healthy people, while prediabetes tended to increase the risk of SCAS.

Aim To elucidate the therapeutic effect of ginsenosides, berberine and jasminoidin after given a-lone or treatment with combination on the focal cerebral ischemia rats and study the compatibility mechanism. Methods We determined 12 endogenous amino acids in serum of rats after cerebral ischemia over 12 hours with RRLC-QQQ to evaluate the integrated role of YQJD at the dosage of 25 mg·kg-1 and 5 mg·kg-1 . Generally accepted methods were used, including be-havior test, One-Way AVONA, PLS-DA, as well as PCA to evaluate the injury induced by focal cerebral is-chemia. Results The score of neurological deficits and the level of five amino acids, namely Glu, Asp, Met, Hcy, Phe in the combination of ginsenosides, berberine and jasminoidin group in the dosage of 25 mg ·kg-1 and 5 mg·kg-1 significantly decreased (P<0. 05, P<0. 01) compared to those of model group. For another, the largest contribution group in the three principal components of PC1 , PC3 , PC4 at the dosage of 25 mg/kg and the six principal components PC1 ~PC5, PC7 in 5 mg·kg-1 was the combination of gin-senosides, berberine, jasminoidin group. Conclusions The results suggest that the efficacy of the combina-tion of ginsenosides, berberine and jasminoidin is su-perior to the combination of two or any single compo-nent, which can significantly improve the metabolic disorder of the endogenous amino acid after cerebral is-chemia. And it could be speculated that ginsenosides may play a more important role than berberine and jas-minoidin in regulating the level of amino acid metabo-lism.

Objective To analyze the genetic characterization of VP1 region of Coxsackie virus A10(CVA10)isolated from clinical specimens of hand, foot and mouth disease(HFMD) patients in Shandong Province. Methods Clinical specimens were collected from some of HFMD patients from 2008 to 2009. The virus was isolated by cell culture. Total RNA was extracted, and the VP1 genes of the isolates were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and sequenced. The genotypes were identified by molecular typing method and bioinformatics analysis.Homologous comparison and phylogenetic analysis of representative CVA10 strains were performed.Homologous comparison between the Shandong isolates and strains obtained from GenBank were performed and phylogenetic analysis of some representative CVA10 strains were performed. Results Three hundred and thirty viruses strains were isolated from 760 clinical specimens collected from HFMD patients, and 17 of them were identified as CVA10. The homologies of nucleotide and amino acid of the 17 CVA10 strains were 82.3%-100.0% and 94.2%-100.0%, respectively. Compared with the prototype strain of CVA10 (Kowalik/USA/2003), the homologies of nucleotide and amino acid were 75.6%-76.8% and 90.2%-93.2%, respectively. Interestingly, Shandong CVA10 strains were clustered into two distinct subgroups in the phylogenetic tree. Conclusions CVA10 is one of the causative agents of HFMD. Two independently circulating subgroups of CVA10 exist in Shandong province.

Objective To explore the pathway of continuous rehabilitation intervention in community stroke patients and to evaluate its effect. Methods Stroke patients (64 cases) were selected from Yuetan community as the rehabilitation group by objective sampling based on inclusive and exclusive standard and 64 stroke patients wre selected from other community in Xicheng district as the control group. At the same time, 16 doctors and nurses from 10 clinics of Yuetan community health service center were trained and they gave reha-bilitative intervention to the rehabilitation group. After intervention for 6 months, the effect of rehabilitative in-tervention was evaluated compared with the control group who did not receive rehabilitative intervention. Re-suits The Fugl-Meyer score of the rehabilitation group was (76.14±12.48), the score of the control group was (19.36±14.32),which had significant difference compared with the rehabilitation group, P < 0.05. The Batthel index of the rehabilitation group was (72.25±10.22), the index of the control group was (22.62±9.71),which was significantly different from that of the rehabilitation group, P < 0.05.Besidcs, the rate of knowing health knowledge and healthy exercise in the rehabilitation group was higher than that of the control group, P < 0.05. Condusions The rehabilitation information net and systemic community rehabilitation intervention can im-prove the motor ability and the ability of daily activity for patients with stroke.

OBJECTIVETo investigate pathologic and differential diagnostic features of pediatric Burkitt lymphoma (BL).

METHODSA total of 20 cases of pediatric BL were retrospectively reviewed for their clinical and pathologic profiles. Bone marrow aspiration specimens were available in all cases and bone marrow biopsies were available for immunohistochemical study in 18 cases. Flow cytometry study was available in 16 cases. MYC translocation by FISH method was performed in 11 cases.

RESULTSAtypical lymphocytes with cytoplasmic vacuoles were found in bone marrow smears in all 20 cases and peripheral blood films in all 19 available cases. The bone marrow biopsies showed infiltration by uniform medium-sized atypical lymphocytes with multiple small nucleoli but without the starry-sky pattern in all 18 cases. Immunohistochemistry showed the following results in all 18 cases: positive for CD20, PAX-5, CD10, CD34 and TdT, but negative for bcl-2 and CD3 with Ki-67 > 95%.Flow cytometry showed CD19+CD20+CD10+FMC7+CD22+TdT-CD3- in 16 cases, including κ+ in 8 cases, λ+ in 7 cases, and κ-λ- in 1 case. MYC gene rearrangement by FISH was observed in 10 of the 11 cases.

CONCLUSIONSThe histopathology of BL is distinct, including atypical lymphocytes with cytoplasmic vacuoles in bone marrow aspirate, lack of starry-sky patternin bone marrow biopsy. Generally, the diagnosis should be made with a combined immunophenotype and FISH approach. Pediatric BL must be distinguished from DLBCL and B-cell lymphoma, unclassifiable, which has intermediate features between DLBCL and Burkitt lymphoma.
