: ObjectiveTo study the effect of acupuncture on resistin and adiponectin and its gene expression in type 2 diabetic rats.MethodsThe rats of type 2 diabetes model were randomly divided into acupuncture group, rosiglitazone group and model control group, meanwhile 8 normal rats were assigned as the normal control group. The changes of total cholesterol(TC), triglycerides(TG), high density lipoprotein-cholesterol(HDL-C) and fasting plasma glucose (FPG) were measured. The expression of resistin gene and adiponectin gene in the adipose tissue was determined with RT-PCR. The level of serum resistin and adiponectin in type 2 diabetes rats were observed before and after acupuncture.ResultsThe levels of TC, TG, FPG resistin lowered obviously, and the levels of HDL-C adiponectin raised significantly. The expression of resistin gene lowered obviously. The expression of adiponectin gene significantly raised in acupuncture group, compared with the model control(P＜0.01, P＜0.05).ConclusionAcupuncture can decrease resistin gene expression, raise adiponectin gene expression, accordingly release insulin resistance.

ObjectiveTo evaluate th effect and safety of tolterodine on detrusor hyperreflexia of patients with spinal cord injury.Methods20 cases of spinal cord injury patients with detrusor hyperreflexia were treated with tolterodine (2mg, twice daily), and the data of urodynamics and voiding diary before and after treatment were evaluated.ResultsAfter 12 weeks of treatment, it showed a significant increase from baseline in mean voiding volume (P<0.01), functional bladder volume (P<0.05) and interval of voiding (P<0.01). The bladder volume at first contraction significantly increased from (62.62±36.37)ml to (126.75±34.64)ml (P<0.01), the maximal pressure of detrusor contraction significantly decreased from (74.81±28.60) cm H2O to (61.90±16.22) cm H2O (P<0.05), the maximal amplitude of wave significantly decreased from (47.24±30.42) cm H2O to (39.36±25.28) cm H2O.ConclusionTolterodine is effective and safety to detrusor hyperreflexia of patients with spinal cord injury, and has a better therapeutic compliance and less adverse reactions.

Objective To investigate the clinical characteristics, diagnosis and treatment of acute mesenteric venous thrombosis(MVT) in the elderly. Methods The clinical features, diagnosis, treatments and prognosis of 10 aged cases with acute MVT were retrospectively analyzed. Results The chief complaints of the 10 cases were different degrees of abdominal pain, which not paralleled with abdominal signs. The accompanying symptoms were nausea, vomiting and bloody stools and so on. All of these patients were misdiagnosised as pancreatitis, appendicitis or intestinal obstruction and so on. diagnosis of two cases was confirmed by ultrasound, 8 by CT. At the same time, 2 cases underwent angiography examination. Of the 8 cases who underwent operation, 5 cases were cured, 3 cases died (1 died of toxic shock and 2 died of multiple organ failure ). Two cases underwent conservative intervention thrombolysis. Conclusions It is essential to improve the knowledge of acute MVT,especially its intricate clinical characteristics, high rates of misdiagnosis and mortality. Early proper diagnosis is crucial. The main treatment is operation and conservative intervention thrombolysis can be performed in the patients whose bowel has not necrosed yet.

Objective To summarize the clinical features of mercury poisoning diagnosed by blood and urine tests for improving the diagnosis and treatment of the disease.Methods Poisoning causes,clinical manifestations,diagnosis,treatment and prognosis were retrospectively reviewed in 92 in-patients with mercury poisoning in our hospital from January 2000 to April 2010.Results Of the 92 patients,37 were male and 55 were female with an average age of 33.1(2-65)years old.The mercury poisoning was caused by occupational exposure and non-occupational exposure,such as iatrogenic exposure,life exposure and wrong intake or suicidal intake of mercury-containing substances,mainly through respiratory tract,digestive tract and skin absorption.The most common clinical symptoms were as the followings:nervous system symptom,such as memory loss in 50 eases(54.3%),fatigue in 34(37.0%),numb limb in 25 (27.2%),dizziness and headache in 22(23.9%),cacesthesia in 20(21.7%),fine tremor(finger tip,tongue tip,eyelids)in 15(16.3%),insomnia and more dreams in 12(13.0%);gastrointestinal symptoms:nausea in 16 (17.4%),abdominal pain in 14(15.2%),stomatitis in 5(5.4%);joint and muscle symptoms:muscle pain in 16(17.4%),joint pain in 5(5.4%);cardiovaseular system:chest tightness,hean palpitations in 6(6.5%);urinary system:edema in 9(9.8%);other system:hidrosis in 20(21.7%).After the treatment with sodium dimercaptopropane sulfonate (DMPS),the symptoms were gradually alleviated.Their gastrointestinal,cardiovascular symptoms were alleviated within 2 weeks;neurological symptoms were alleviated within 3 months;kidney damage showed a slower recovery and could be completely'alleviated within 6 months.Conclusions Because of its diverse clinical symptoms,the mercury poisoning was easy to misdiagnosis and missed diagnosis:therefore the awareness of the disease should be further enhanced.Leaving from the poisoning environment timely and giving appropriate treatment with DMPS will lead to a satisfactory prognosis.

OBJECTIVETo explore the character of inorganic elements in Polygonum multiflorum.

METHODThe contents of elements such as Al, B, Ba, Ca, Cu, Mn, Mg, Fe, Na, Ni, P, Se, Sr, Ti and Zn in nine P. multiflorum samples were determined by means of ICP-AEC. The results were used for the development of element distrubution diagram. The principal component analysis and one-way ANOVA of SPSS were applied for the study of characteristic elements in P. multiflorum.

RESULTThe contents of Al, Ca, K, Mg, Sr,Ti in wild P. multiflorum were remarkable higher than those in cultured P. multiflorum, and there was no significant difference between cultured and wild in the other elements. Five principal components which accounted for over 90% of the total variance were extracted from the original data. The analysis results show that Al, B, Ba, Fe, Na, Ni, Ti, Ca and Sr may be the characteristic elements in P. multiflorum. The element distrubution diagram of the sample from Tianyang was remarkable different comparing with the others.

CONCLUSIONThe principal component analysis could be used in data processing in inorganic elements.

OBJECTIVE: to explore the relationship between the maxillary sinus volume and the amount of alveolar bone, and the effect of molar loss upon the maxillary sinus was further analyzed,by measuring adult maxillary sinus volume, sinus ridge distance, and calculating the gasification coefficient of maxillary sinus. METHOD: One hundred and ninety cases (361 maxillary sinus) with CT examinations were collected, they were divided into group A and group B, 121 cases (242 maxillary sinus) of normal subjects served as group A, 42 cases (65 maxillary sinus) with molar part off were B group, in which 31 maxillary sinus with a molar loss were group B1,22 maxillary sinus with two molar loss were B2 group,12 maxillary sinus with three molar loss (one molar remains) were B3 group, 27 cases (54 maxillary sinus) with upper teeth off were C group. Bymeasureing the maxillary sinus volume, sinus ridge distance and the size of the maxillary sinus, calculating the gasification coefficient, we analyzed the relationship between maxillary volume and sinus ridge distance, and comparatively analyzed the differences among the three groups in the size, gasification coefficient, volume of maxillary sinus and sinus ridge distance. RESULT: In the normal group,the volume of maxillary sinus and sinus ridge distance had a correlation coefficient of -0. 63,(P< 0.05); Sinus ridge distance in group A was larger than the other two groups (P<0.05), and larger in B group than in C group (P<0. 05), anteroposterior maxillary sinus diameter and reft-right diameter in C group was greater than in A group and B group(P<0.05), group C gasification coeffiecent was less than A group and B group (P<0. 05). CONCLUSION The volume of maxillary sinus is negatively correlated with the amont of alveolar bone; Upper teeth's shedding promotes maxillary sinus deformation; Maxiuary sinus volume has a tendency to decrease.

Objective:To evaluate the effect of percutaneous coronary intervention(PCI) on mitral regurgitation(MR) in patients with acute myocardial infarction(AMI).Methods: A total of 213 AMI patients were divided into PCI group(n=87,(PCI +) medication) and medication group(n=126,medication) according to the treatments they received.Echocardiographic examination was conducted in patients during admission and 6 months follow-up.Color Doppler was used to determine the degree of MR.Echocardiogram indices included MR degree,left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVEDs),left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),and left ventricular ejection fraction(LVEF).Results: The overall incidence of MR was 28.6% in 213 patients during admission.The MR incidence in patients with acute inferior myocardial infarction was higher than that in patients with other parts of infarction((34.5%) vs 22.3%,P0.05),while the incidence in medication group increased significantly than that during admission(43.7% vs 30.2%,P

Objective：This study was designed to investigate the cell adhesion molecule, estrogen receptor (ER), and progesterone receptor (PR) expression and their significance in invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC)of breast. Methods：Immunohistochemistry staining (labeled streptavidin-biotin method) was used to detect E-cadherin, α -catenin， β -catenin， γ -catenin, ER and PR expression in breast invasive carcinoma (32 cases of the IDC and 10 cases of the ILC). Results：The expression rates of E-cadherin, α -catenin， β -catenin， γ -catenin showing loss or mostly reduced in IDC were 18.7％ ， 75％ ， 43.8％ , and 81.3％ , respectively. The expression rate of E-cadherin, α -catenin， β -catenin， γ -catenin expression showing loss and mostly reduced in ILC were 30％ ， 70％ , 50％ , and 80％ , respectively. There was a positive relationship between the expression of α -catenin and β -catenin in IDC. γ -catenin expression showing loss and mostly reduced in breast invasive carcinoma was associated with the presence of lymph node metastasis. ER expression correlated with PR expression in IDC. Conclusion：In contrast to E-cadherin expression, α -catenin， β -catenin， γ -catenin expression may be almost identical in ILC and IDC, which is showing loss and mostly reduced protein expression in carcinoma cells of breast invasive carcinoma. γ -catenin expression showing loss and mostly reduced is a predictor for the presence of lymph node metastasis. ER, PR and E-cadherin, α -catenin， β -catenin， γ -catenin expression may be two kinds of independent prognostic markers for breast invasive carcinoma.

Objective　To study E-cadherin associated proteins α-、β-、γ-catenin expression and their significance in invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC) of breast. Methods　Immunohistochemistry staining (labeled streptavidin-biotin method) was used to detect α-、β-、γ-catenin expression in invasive breast carcinoma (19 cases of ILC and 32 cases of IDC ). Results　The loss and reduction rate of α-、β-、γ-catenin expression in ILC was 78.9% (15 cases)，52.6%(10 cases) and 84.2%(16 cases), respectively. The rate of α-、β-、γ-catenin expression showing loss and reduction in IDC was 75.0%(24 cases)，43.8%(14 cases) and 81.3%(26 cases), respectively. The staining intensity of α-、β-、γ-catenin expression in invasive carcinoma of breast was weaker than that in foci of carcinoma in situ (semiquantitative grading). There was a positive relationship between the expression of α-catenin and β-catenin in invasive breast carcinoma. No significant association was seen between reduced protein expression of α-、β-、γ-catenin and the development of lymph node metastasis. Conclusion　α-、β-、γ-catenin expression was almost identical in ILC and IDC of breast, showing significant loss and reduction of protein expression in the carcinoma cells of invasive breast carcinoma, suggesting that α-、β-、γ-catenin may lose their normal adherent ability in the pathogenesis of invasive breast carcinoma.
