Objective To investigate the expressions of CYCLIND1 CDK4 in pancreatic cancer and their relationship with clinlicopathological parameters.Methods Immunohistochemical detector with new second generational tow steps method was used to detect the expressions of CYCLIND1 CDK4 and PCNA in 48 cases of pancreatic cancer and 14 cases of chronic pancreatitis.Results The expressions of CYCLIND1 CDK4 proteins in pancreatic cancer were 70.85%(34/48)and 62.50%(30/48) respectively.The CYCLIND1 and CDK4 proteins were increased(P

The paper described the necessity of the doctor-patient information exchange platform,and defects found in existing platforms. Such a platform is conducive to higher hospital informationization, better patient satisfaction, and better social and economic benefits of the hospital.The hospital may improve its quality of care and patient satisfaction by means of the platform

Bartter′s syndrome(BS) is a rare renal tubular diseases and an autosomal recessive hereditary disease. The characteristic findings are hypokalemia, metabolic alkalosis, and raised serum renin and aldosterone levels. Combination of metabolic syndrome with Bartter′s syndrome has not been reported so far. Here in, we report a case in order to call attention to the diagnosis and treatment of typical Bartter′s syndrome combined with metabolic syndrome.

Objective To sequence the antigen-encoding genes esxA,fbpB and Rv2660c from clinical isolates of Mycobacterium tuberculosis (MTB) in tuberculosis children and study the polymorphisms.Methods A total of 135 isolated strains were amplified for gene sequences of esxA,fbpB and Rv2660c by PCR,and the products were sequenced respectively.The results of sequencing were compared with the corresponding gene sequences of standard strain H37Rv and human T and B cell epitope sequences from immune epitope database (IEDB).The genetic diversities of the gene sequences of esxA,fbpB and Rv2660c were analyzed.Results Among the 135 strains,no gene polymorphisms were found in esxA and Rv2660c.But fbpB had genetic diversities in 66 clinical isolates (48.89％).The 5 single nucleotide polymorphism (SNP) mutations in fbpB affected 8 (14.81％) T cell epitopes and 9 (24.32％) B cell epitopes.The dN and dS values of whole fbpB gene were 0.000 120 and 0.002 126,respectively.The dN and dS values of T epitopes areas were 0.000 067 and 0.002 382 respectively,those of non-T epitopes area were 0.000 408 and 0.000 470,respectively,those of B epitopes areas were 0.000 063 and 0.00 2380,and those of non-B epitopes areas were 0.Conclusion The gene sequences of esxA and Rv2660c are conservative,and that of fbpB contains genetic diversities.Its polymorphisms may influence the function of antigen Ag85B,and thus affect the efficacy of vaccine H56.

ObjectiveTo research a way to verify whether the stomach duct is misplaced into the trachea.MethodsThe air pressure of the stomach duct placed in the stomach or in the trachea were measured using a water bottle.ResultsThe air pressure of the stomach duct was (1±0.45)cmH2O When it was put in the stomach, and was (7±2.03)cmH2O when it was put in the trachea(P<0.01).ConclusionsWhen it is impossible to draw out acerbic substances from the stomach to verify whether the stomach duct is placed in the stomach or misplaced in the trachea, measure the air pressure stomach duct by a water bottle can be used as substitute, which is reliable and convenient.

目的帮助截瘫患者解决便秘的痛苦及促进排便功能的恢复。方法卫生棉条刺激排便和定时排便训练。结果治疗组的有效率为90.49% ,明显高于对照组的33.33%(P<0.01)。结论棉条刺激和定时排便训练能使患者短时间内大量排便并对排便功能的恢复有促进作用。

目的探讨住院偏瘫患者的“偷行”行为与跌倒的关系,以防止患者跌伤。方法自制“偏瘫患者偷行动机与行动问卷”调查表,发给404例住院偏瘫患者填写或由他人协助填写。结果56.93%的被调查患者有偷行动机,5.44%有偷行行为,占有偷行动机人数的9.48%,发生跌倒的占有偷行行为的86.36%,跌倒患者中出现跌伤者占10.52%。结论偏瘫患者中普遍有偷行动机,相当一部分患者有偷行行为,偷行者跌倒率高,容易跌伤,故偷行行为是引起住院偏瘫患者跌伤的主要原因之一 ,应引起医护人员重视,并列为评估患者跌倒因素的内容之一。

Objective:To study performed of develop a mice model of allergic diseases induced by crude extractings from populus pollen.Methods: A total of 60 BALB/c mice were divided randomly into there groups:normal control group,Albumin Egg(OVA) group and populus pollen model group with 20 in each.Mices were repeatedly sensitized by intraperitoneal injections of OVA or crude populus pollen extract every 5 d for four doses.Five days after the last sensitization,mices were repeatedly challenged by once daily antigen from 21-25 d.The changes of inflammatory cells in bronchoalveolar lavage fluid(BALF) were stained with hematoxylin and eosin(HE) to evaluate the degree of allergic inflammation.PAS staining was used to observe the secretion of airway mucus;The changes of the nasal mucosas and lungs of mice were stained with HE to evaluate the degree of allergic inflammation.And the average optical density of IL-4 and IFN-γ positive cells in lung tissue was measured by immunohistochemistry.The total IgE in the serum was also measured by enzyme-linked immunoassay(ELISA).Results: Compared with the mice in normal control group,those in OVA group and model group developed obvious allergic inflammation in the nasal mucosas and lungs,and increased airway mucus secretion.The number of inflammatory cells including eosinophil and neutrophils markedly increased in BALF smear.The average optical density of IL-4 positive cells in lung tissue was all increased in OVA group and model group compared with those in normal control group,and the average optical density of IFN-γ in lung tissue was on the contrary.The total IgE in the serum were all increased in OVA group and model group compared with those in normal control group,and the IFN-γ in the serum was significantly reduced in OVA group and model group compared with those in normal control group.Conclusion: Taken together,crude populus pollen extract can successfully induce a mice model of allergic diseases.This model is a useful tool in studying the mechanisms of allergic disease.

Objective To investigate the effects of repeated neonatal administration of dizocipline maleate (MK-801), the N-methyl-D-aspartate (NMDA) receptor antagonist, on the expression of NMDA receptor subunits NMDAR 1 (NR1), NMDAR2A (NR2A), NMDAR2B (NR2B) and the protein levels of nerve growth factor (NGF) in neonatal rats. Methods Neonatal Sprague-Dawley (SD) rats were randomly divided into research group and control group, with 15 ani-mals in each group. Rats were administrated subcutaneously with MK-801 or normal saline from postnatal day (PND) 5 to PND14 (0.25 mg/kg, twice a day). The expression levels of NR1, NR2A, NR2B and NGF were examined on PND15, PND42 and PND70 in the prefrontal cortex and hippocampus. Results At PND15 (neonatal period), there were no signifi-cant differences in the expression levels of NR1, NR2A, NR2B and NGF in the prefrontal cortex and hippocampus be- tween the two groups (P>0.05). At PND42 (adolescence), NGF protein levels in the prefrontal cortex was significantly low-er in research group than in control group [(56.19±37.87) vs. (152.54±53.92), P<0.01]. At PND70 (adulthood), the expres-sion of NR1, NR2A in the hippocampus was significantly higher in research group than in control group [NR1:(149.55%± 27.00%) vs. (100.00%±32.08%);NR2A:(171.54%±19.85%) vs. (100.00%±51.04%). P<0.05]. Conclusion Neonatal re-peated treatment of MK-801 increases the expression of NMDA receptor subunits NR1, NR2A in the hippocampus in adulthood while decreases the expression of NGF in the prefrontal cortex in adolescence, suggesting that neonatal block-ade of the NMDA receptor may influence the growth and development of the nervous system.
