Objective To study the effect of apolipoprotein E (ApoE) polymorphism on serum lipids and the relationship between apolipoprotein E polymorphism and coronary heart disease (CHD).Methods Polymerize chain reaction (PCR) and HhaI digestion were used for the detection of apolipoprotein E genotype on 71 patients with CHD and 69 control subjects.Results The frequencies of apolipoprotein E4 allele and E3/4 genotype were obviously increased in CHD group than in control group (P<0.01,P<0.05). Conclusion The apolipoprotein E polymorphism is related to the occurrence of coronary heart disease; apolipoprotein E4 allele is one of the most important hereditary factor for the occurrence of CHD.

Objective\ To determine the distribution of the sympathetic postganglionic neurons innervating the uterus of uterine tube in hens. Methods\ CB\|HRP was injected into the wall of the uterus(shell gland)of hens. Results\ The hens uterus was innervated by the bilaterally sympathetic postganglionic neurons from T\-1 to LS\-\{13\} segments of the sympathetic trunk,splanchnic and adrenal ganglia.CB\|HRP labeled neurons in the left side were prominant.In the sympathetic trunk,a good lot of labeled neurons were accummulated in the segments both T\-5\|LS\-2 and LS\-8\|LS\-\{12\}. The greatest concentration of the neurons was in T\-7 and LS\-\{10\}. Conclusion\ The hen's uterus was innervated by the bilaterally sympathetic ganglionic neurons although it was the unilateral organ.\;

[Objective]To investigate the clinical value of different magnetic resonance(MR) pulse sequences in the diagnosis of bone contusion.[Method]Forty-five patients with bone contusion underwent magnetic resonance imaging(MRI).All cases underwent computed radiography(CR),digital radiography(DR)or computed tomography(CT)and no bone fracture were revealed.Complications included swelling、pain and limit activity.The sagittal,coronal and transversal scanning were performed by Siemens Novus1.5T magnetic resonance imaging.The body coil were used on spines and knee coil on knees.MR pulse sequences included spin echo T1WI,Turbo spin echo T2WI,fl-2d T2WI and fat suppressed sequence T2WI.[Result]In 45 cases with bone contusion,44 cases were revealed on spin echo T1WI(97.7%),37 cases on Turbo spin echo T2WI(82.2%),24 cases on fl-2d T2WI(75%),45 cases on fat suppressed sequence T2WI(100%).The fat suppressed sequence T2WI was superior to TSE T2WI(

Objective:To explore the perioperative dynamic changes of cellular immune function and its clinical significance in patients with chest surgery.Methods:The numbers of CD3、CD4、CD4/CD8、CD8 T lymphocyte and nature killer(NK) cells in peripheral blood were examined in 45 patients with chest surgery before operation and 1、3、5 and 7 days after operation by flow cytometry.45 patients were devided randomly into groups.The perioperative changes of T lymphocyte subsets and NK cells were compared among mediastinal disease,pulmonary operation,esophagus and gastric cardia surgery.Results:CD4/CD8 decreased 1 day after surgery and CD4 decreased at the 3rd postoperative day in patients with chest surgery.In patients with mediastinal disease,CD4/CD8 decreased 1 day after surgery and CD4 decreased at the 3rd postoperative day.In patients with pulmonary operation,CD8 decreased at the 1st day and 7th day after surgery.NK cells decreased at the 5th postoperative day CD3 increased at the 5th day after surgery.CD4/CD8 increased at the 7th day after operation.In patients with esophagus and gastric cardia surgery,CD4/CD8 decreased 1 day after operation,CD3 and CD4 increased at the 7th postoperative day.All differences are statistically significant( P

ObjectiveTo explore the relationship between plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-β-synthase (CBS), and cerebral thrombosis.Methods87 subjects with first-ever acute cerebral thrombosis and 80 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion and that in CBS was determined by amplification refractory mutation system (ARMS).ResultsThe fast plasma Hcy level in the patient group was (15.28±4.33)μmol/L significantly higher than that ( 11.32 ±3.86)μmol/L in the control group (P<0.001). Different genotype had different influence on the plasma Hcy levels. There were no differences in genotype frequencies or allele frequencies between the patient group and control group (P>0.05).ConclusionCommon mutations in MTHFR, CBS G919A and CBS T833C lead to hyperhomocysteinemia. Hyperhomocysteinemia, but not common mutations in MTHFR and CBS is associated with the increased incidence of cerebral thrombosis.

Objective To analyze the incidence,clinical feature and the risk factors of invasive fungal infection in pediatric intensive care unit (PICU). Methods We retrospectively summaried the invasive fungal infection in our PICU from Jan 2007 to Dec 2009 in order to analyze the incidence, clinical feature and the risk factors of invasive fungal infection in PICU. Multiple clinical data were collected such as pediatric critical illness score, mechanical ventilation, urinary drainage tube, indwelling gastric canal and continuous blood purification. Results ( 1 ) The incidence rate of invasive fungal infection was 1.65 % ( 35/2 116 ). The morbidity was 20. 00% ( 7/35 ). ( 2 ) Mean infected day was ( 10. 4 ±- 8. 3 ) d after admission. The clinical manifestations included fungal pneumonia( 60. 0% ), peritonitis ( 14. 3% ), urinary tract infection ( 11.4% ),intestinal tract infection(8. 6% ) ,sepsis(2. 9% ) and meningitis(2. 9% ). All of the patients had used broad spectrum antibiotic. (3) The risk factors of invasive fungal infection included lower pediatric critical illness score, mechanical ventilation, indwelling gastric tube, urinary drainage tube and continuous blood purification.(4) Candia albicans was the predominant pathogen in invasive fungal infection. Conclusion Invasive fungal infection has become one of the main nosocomial infection in PICU. Lung is most commonly involved and candida albicans is the major pathogen. Using antibiotics appropriately, decreasing unnecessary invasive performance,and rationally using antifungal agent mi.ght be effective strategy for invasive fungal infection in PICU.

Objective To observe the influence of health education on compliance of children nn-dergoing megacolon radical operation. Methods A questionnaire investigation was conducted on compli-ance of children undergoing megncolon radical operation before and after health education. ResultsCompliance of children patients and their family members increased after health education (P<0.05).Conclusions Health education could improve the compliance of children patients and their family mem-bers as well as the cognition about the disease knowledge so that the rehabilitation was facilitated.

Objective To evaluate two methods measuring alveolar bone loss by micro computed tomography (micro-CT)based on periodontitis model in mice.Methods The silk ligatures were tied around the right maxillary second molars of mice to induce periodontitis model.The right half maxillaries of mice model were harvested for micro-CT analysis.Three dentists were recruited for the measurement with two different methods:Modified tomography (T) method and reconstruction (R) method.Accuracy and consistency of each method were estimated by standard deviation (SD).Results The SDs of R method managed by the same operator (measurement for 3 times) or different operators (3 operators) were 34.87μm and 35.67 μm respectively,while that of T method was 7.82 μm and 14.24 μm respectively.The SDs of T method were significantly lower than those of R method (both P＜0.05).Conclusion T method is more accurate and consistent than R method for evaluating alveolar bone loss in mice periodontitis model.

Objective To compare the differences of prescription pattern, adverse events, economic burden and drug-use adherence between preferred mood stabilizers and preferred antipsychotics in patients with bipolar disorder. Methods We investigated 240 cases of patients with bipolar disorder from 39 mental health institutions in 11 cities in Hebei province. The self-made questionnaire was used to investigate the demographic information, disease characteris-tics, prescription pattern and medical expense. The clinical global impression scale-severity of illness (CGI-SI) was used to assess the disease severity. The treatment emergent symptom scale (TESS) was used to assess the adverse drug reac-tions. The medication adherence rating scale (MARS) was used to assess drug therapy compliance in patients. Results One hundred fifty-two patients (63.3%) used antipsychotics as the first choice (antipsychotics group), 88 patients (36.7%) used mood stabilizers as the first choice (mood stabilizers group). The number of patients in-patient (90.1%vs. 76.1%), patients with psychotic symptom (27.0%vs. 11.4%), incidences of adverse events (46.1%vs. 31.8%), drug daily cost (me-dians 12.00 yuan vs. 8.37 yuan) and drug total cost (medians 344.61 yuan vs. 144.64 yuan) were larger in antipsychotics group than in mood stabilizers group (P<0.05). There was no significant difference between two groups in pattern of pre-scription, severity of adverse events and total scores of MARS (P>0.05). Conclusion The bipolar disorder patients more frequently use antipsychotics as the first choice in Hebei province. The use of antipsychotics does not alter the combina-tion medication pattern. In addition, antipsychotics cause a higher incidence of adverse events and heavier economic bur-den compared with mood stabilizers, suggesting that mood stabilizers should be the first choice to bipolar disorder.
