Objective To study effects of bitter almond on interstitial cells of Cajal (ICC) in old rats with slow-transit constipation (STC) and analyze mechanism of the gut purge of bitter almond.Methods Forty-five old SD rats were randomly divided into blank control group,model control group,bitter almond-treated group randomly (n=15,each).Compound phenanthroline was used to build the model of STC model.The bitter almond-treated group was given with bitter almond apozem,the other two groups were given with the same amount of saline.After 10 days,the carbon powder propulsion rates in the intestine were measured and specimens were taken.The ICC changes in terms of the number and distribution were observed by immunohistochemical method.The protein and mRNA expressions of c-kit in ICC were measured by Western blot and reverse transcription-polymerase chain reaction(RT-PCR).Results Compared with blank control group [(68.6 ± 6.0) ％,the carbon powder propulsion rates in the intestine in model control group[(47.7±± 1.7)％]were declined (P＜ 0.01).The areas of c-kit positive cell in colon were declined[(638.0 ± 23.5) μm2 vs.(723.7 ± 30.8)μm2]in model vs.blank control (P＜0.05).The mRNA expression of c-kit gene in ICC was declined [(0.3±0.1) vs.(1.0±0.1)] (P＜0.05),the expression of c-kit protein in ICC were declined[(0.2±0.2) vs.(0.5±0.2)] (P＜0.05).Compared with model control group[(47.7± 1.7)％],the carbon powder propulsion rates in the intestine in bitter almond group were increased[(63.4± 3.3)％ vs.] (P ＜0.01).The mRNA expression of c-kit gene in ICC were increased in bitter almond group (0.9 ±0.2) vs model control group[[(0.3±0.1)] (P＜ 0.01).The expression of c-kit protein in ICC were increased in bitter almond group[(0.5±0.3) vs.in model control 0.2±0.2)] (P＜0.01).Conclusions The bitter almond can promote the expression of c-kit mRNA and protein in colonic tissue of old STC rat interstitial and repair a fraction of ICC of STC rat interstitial,which promote intestinal peristalsis in slow-transit constipation rats.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma with highly heterogeneous clinical course. How to recognize patients with high risk is coming into the focus of the 57th American Society of Hematology (ASH) annual meeting. The International Prognostic Index (IPI) score as a classic prognostic system is challenged by variety of new prognosis systems. The tumor microenvironment plays an important role in progression of lymphoma, and its prognostic value draw much more attention. The value of PET-CT for prognosis of DLBCL has also been affirmed in this meeting.

Objective　To study the clinico-pathological features of primary adrenal lymphoma (PAL).　Methods　2 cases of PAL were reviewed and studied.　Results　The age of the 2 patients was 45 and 57.The presenting symptoms were nonspecific.Histologically,the neoplasm was composed of numerous medium-sized cells with round nucleus,usually 1-2 in number and with relatively abundant basophilic cytoplasm.The neoplastic cells showed frequent mitosis.Immunohistochemically,the tumor cells were strongly positive for LCA,L26 and CD74 while negative for UCHL-1,S-100 protein and CK. One case was discharged 3 months after operation because of dyscrasia and the other was lost on follow up.Prognosis of PAL was poor.　Conclusions　PAL is extremely rare with a high grade of malignancy.The diagnosis could be made on histopathological studies and immunohistochemical studies.

Objective This report investigate the intervention effect of the water extract of Alpinia oxyphylla Miq. fruit (AOF)on memory impairment and the mechanism in cerebral ischemia rats. Methods 48 Rats were randomly divided into sham-operated group(n=12), ischemia group(n=12), AOF group Ⅰ( n= 12)and AOF group Ⅱ (n= 12). The model of transient cerebral ischemic/reperfusion was made by bilateral occlusion of common carotid arteries in rats and combination with reducing blood pressure with an abdominal injection of so-dium nitroprusside. Learning-memory ability was observed by step through test. The content of NO and the activi-ties of NOS were measured in hippocampus. Results In step through test,the latency in ischemia group[(143.8±65.2)s]significantly decreased, the number of errors (8.9±4.2 ) significantly increased compared with sham-operated group [latency: (257.2±67.1 ) s; number of errors: (1.7±1.1 ), P<0.01 ]. The latency in AOF group Ⅰ and AOF group Ⅱ[(186.5±46.2) s, (193.4±43.7 ) s ] significantly increased, the number of errors (6.1±2.9,5.2±2.1 ) significantly decreased compared with ischemia group(P<0.05, P<0.01). In hippocampus, the content of NO and the activities of NOS in ischemia group [(56.53±27.42) nmol/mg prot, (17.23±5.64) nmol/mg prot] significantly increased compared with sham-operated group[ (40.02±17.9 ) nmol/mg prot, ( 10.46±6.15)nmol/mg prot], and in AOF group Ⅰ and AOF group Ⅱ [content of NO:group Ⅰ (46.60 ±20. 26)nmol/mg prot,group Ⅱ (42.38±21.23) nmol/mg prot ;activities of NOS:group Ⅰ (13.98±5.13 ) nmol/mg pint,group Ⅱ(13.61±5.27) nmol/mg prot] significantly decreased compared with ischemia group(P<0.05). Conclu-sion AOF could significantly ameliorate the memory impairment in cerebral ischemic rats. Its effects may be in-volved in the decrease of content of NO and activities of NOS in hippocampus.

Purpose：To study the clinical and pathological characteristics of multicentric angiofollicular lymph node hyperplasia (MCD).Methods：Eight patients with histologic diagnosis of angiofollicular lymph node hyperplasia (CD) were identified in the pathologic data base.The lymph node lesions were categorized as PC,Mix and HV types according to the criteria described by Frizzera. Patient with MCD had to have histology of CD within at least one regional group of lymph nodes and all underwent extensive lymphadenectomy.Results：The histologic features of 8 patients were six with PC,one with Mix and one with HV.Five patients presented with systemic symptoms. Three patients had splenomegaly and hapatomegaly. Five patients had local recurrence.Conclusions：MCD tends to recur and has a progressive clinical course with potential for malignancy ,and further study is needed to clarify the pathogenesis. Close follow-up and periodic surveillance are necessary to detect minimal disease and secondary malignant lesions. The patients with MCD should be candidates for multimodality therapy.

With accelerated population aging, traditional pension mode cannot adapt the diversified medical and nursing requirements of the elders. Therefore, it should reposition the function of medical service in pension career and encourage combining medical service with pension service. Through the methods of setting medical insti-tutions in pension institutions with conditions, developing social pension service in medical institutions, pension in-stitutions cooperating with medical institutions,both professional medical service and basic pension service would be offered to the elders, and thus to realize the integration of medical and nursing resources and to improve health con-dition of the elders.

OBJECTIVE:To investigate the effects of TanshinoneⅡA sodium sulfonate injection on levels of P-selectin,glial fi-brillary acidic protein (GFAP),vascular endothelial growth factor (VEGF) and neurological function in patients with acute cere-bral infarction. METHODS:A total of 114 patients with acute cerebral infarction selected from Lianyungang First People's Hospi-tal during Apr. 2013-Apr. 2016 were divided into control group and observation group according to random number table,with 57 cases in each group. Control group was given routine treatment. Observation group was additionally given Tanshinone ⅡA sodium sulfonate injection 40 mg 0.9％ sodium chlonride injection 250 mL,ivgtt,qd. A treatment course lasted for 7 d,and both received 2 courses of treatment. NIHSS scores,the levels of serum P-selectin,GFAP and VEGF were compared between 2 groups before treatment and after 7,14 d of treatment. The occurrence of ADR was also compared. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05). Compared to before treatment,NIHSS score,the levels of se-rum P-selectin and GFAP in 2 groups were decreased significantly after 7,14 d of treatment,while the serum level of VEGF was increased significantly. These indexes of 2 groups after 14 d of treatment were significantly better than 7 d of treatment,except for NIHSS score. Above indexes of observation group was significantly better than those of control group during corresponding period, with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:For acute cerebral infarction, Tanshinone ⅡA sodium sulfonate injection can significantly reduce the levels of serum P-selectin and GFAP,improve VEGF level and promote the recovery of neurological damage with good safety.
