The elements in blood or serum, including calcium, magnesium, copper, zinc, chromium, manganese, nickel, selenium, lead and cadmium were determined in the normal and patients in Nanjing by atomic absorption spectrophotometry. The method used was proved to be reliable being checked by the reference bovine serum and the data obtained in this paper was coincident with those reported by the other authors previously. The relationship between the concentrations of elements and the ages as well as the sexes in the normal was discussed briefly. The concentrations of several of the elements of the patients were significantly different from those of the normal in the same ages.

The differential diagnosis of inguinal and scrotal emergencies in children is difficult and misdiagnosis might be associated with danger or even mortality.Early diagnosis and proper treatment are very important and explorational surgery should be carried out when diagnosis is in doubt.

Objective To investigate the serotype distribution and antimicrobial resistance of the S.pneumoniae strains isolated from children in Humen,and evaluate coverage of the serotypes by several vaccines,especially PCV7.Methods A total of 229 S.pneumoniae strains were isolated from the children treated in our hospital during January 2011 and December 2012. Capsular typing was performed by Quellung reaction.Antimicrobial susceptibility was determined by ATB STREP 5.The data were analyzed by WHONET 5.5 software according to CLSI 2010 breakpoints.Results The main serotypes identified from the 229 S.pneumoniae strains were 19F (146,63.8%),23F (49,21.4%),6B (12,5.2%)and 14 (8,3.5%).The coverage of these serotypes was 95.2% by PCV7,95.2% by PCV11,and 97.4% by PCV13.Of all the S.pneumoniae strains,penicillin susceptible S.pneumoniae (PSSP)accounted for 92.6% (212/229),penicillin intermediate S.pneumoniae (PISP)accounted for 5.7% (13/229)and penicillin resistant S.pneumoniae (PRSP)accounted for 1.7% (4/229).About 95.6%,93.0%, 88.2%,86.5%, 7.0%, 2.2% and 0.9% of the isolates were resistant to erythromycin, clindamycin, tetracycline, trimethoprim-sulfamethoxazole,chloramphenicol,cefotaxime and amoxicillin,respectively.No strain was found resistant to vancomycin or levofloxacin.Conclusions The serotypes 19F, 23F, 6B and 14 are the main prevalent serotypes of S. pneumoniae in children in Humen.PCV7 could cover 95.2% of these S.pneumoniae,indicating its appropriateness for vaccination in Humen area.These S.pneumoniae strains were highly sensitive to vancomycin,levofloxacin and penicillin,but relatively more resistant to erythromycin, clindamycin, tetracycline and trimethoprim-sulfamethoxazole.

Objective To study the relationship between cytokine gene polymorphisms and chronic rejection in kidney allograft recipients and their donors.Methods The cytokine genotypes in- cluding TNF-?,IL-6,IL-10,TGF-?_1 and IFN-?in 144 consecutive first cadaveric kidney allograft re- cipients and 65 corresponding donors were detected by PCR-SSP method.The recipients were followed up for 5 years.The relationship between the TGF-?_1 genotypes of the recipients and donors and the chronic renal allograft rejection was analyzed.Results The incidence of chronic rejection in the recipi- ents with TGF-?_1 high producer genotype(39/91,42.9%)was significantly higher than in those with TGF-?_1 middle or low producer genotype(9/53,17.0%,P0.05).The incidence of chronic rejection in the recipients and donors with TGF-?_1 high producer genotype(4/4)was significantly higher than in those with other genotypes(31/110,28.2%,P

OBJECTIVETo investigate the penile erectile function of hospitalized male patients with cardiovascular diseases, the incidence of erectile dysfunction (ED) in this cohort, and the relationship of ED with cardiovascular diseases and its risk factors.

METHODSUsing a self-designed questionnaire, we conducted an investigation among the hospitalized patients in the Department of Cardiovascular Diseases of the First and Second Affiliated Hospitals of Xi'an Jiaotong University. We measured their body height, body mass index (BMI), waist circumference, hip circumference, and blood pressure, obtained their personal data, past history, metabolic indexes, and erectile function scores by IIEF-5, and analyzed the risk factors of ED using univariate and multivariate logistic regression and OR analyses.

RESULTSTotally, 225 valid questionnaires were included in this investigation, which showed a 66.7% incidence of ED, 15.8% mild, 27.0% mild to moderate, 17.6% moderate, and 6.3% severe. The incident rates of ED in the 18-35 yr, 36-49 yr, 50-65 yr, and > 65 yr age groups were 13.6%, 39.1%, 89.2%, and 91.2%, respectively. Univariate logistic regression analysis manifested that the risk factors of ED in the patients with cardiovascular diseases included age (OR = 3.122, 95% CI 2.040-4.779), smoking (OR = 1.768, 95% CI 1.209-2.584), BMI (OR = 1.261, 95% CI 1.114-1.427), total cholesterol (OR = 1.77, 95% CI 1.339-2.340), TC/HDL (OR =1.715, 95% CI 1.349-2.181), hypertension (OR = 1.717, 95% CI 1.110-2.658), and coronary heart disease (OR = 2.235, 95% CI 1.169-4.275), while multivariate logistic regression analysis showed the risk factors to be age (OR = 4.99, 95% CI 2.264-10.998), financial condition, (OR = 2.804, 95% CI 1.127-6.976), smoking (OR = 2.109, 95% CI 1.179-3.772), BMI (OR = 1.414, 95% CI 1.136-1.760), and TC/HDL (OR = 2.001, 95% CI 1.016-3.943).

CONCLUSIONThe incidence of ED is high in hospitalized patients with cardiovascular diseases and rises with the increase of age. Age, smoking, financial condition, BMI, and TC/HDL are the risk factors of both ED and cardiovascular diseases, and financial condition is closely associated with ED.

Objective To discuss the clinical curative effects of Kaihoujian spray in the treatment of acute suppurative tonsillitis in children. Methods 120 cases of pediatric patients with acute suppurative tonsillitis were selected and randomly divided into the observation group and the control group (60 cases in each group); the control group were given conventional western medicine treatment, while the observation group received Kaihoujian spray on the basis of the control group treatment; clinical symptoms and curative effects of the two groups were evaluated and compared. Results In the observation group, sore throat and fever disappearance time, purulent secretion, tonsil swelling disappearance time and hemogram recovery time were all significantly shorter than those in the control group (P<0.05); after 3 courses of treatment, in the two groups, children temperature, sore throat, tonsil fester and tonsil swollen main symptom scores were all significantly decreased (P<0.05), but the observation group decreased more obviously (all P<0.05). After treatment, C-reactive protein, white blood cell count, neutrophils of the two groups all significantly reduced (P < 0.05), but the observation group decreased more obviously (all P<0.05). Conclusion Using Kaihoujian spray to treat acute suppurative tonsillitis could significantly improve the clinical symptoms and signs, whose clinical curative effect is good, and has no adverse reactions.

Objective To investigate the incidence and its related factors of apathy in patients with acute ischemic stroke. Methods A total of 100 consecutive cases of ischemic stroke patients and 50 health controls were recruited in the present study. Apathy was assessed using modified apathy evaluation scale (MAES). According to the MAES score, acute ischemic stroke patients were divided into apathy group (MAES was more than 14 points) and non-apathy group. The differences of general information, clinical data, national institutes of health stroke scale (NIHSS), Montreal cognitive assessment (MoCA), Hamilton depression scale (HAMD), modified rankin scale (mRS) and the lesion location were compared between the two groups. Differences that showed statistical significance (P<0.05) went into the multi-factor analysis. The Logistic regression analysis was used to estimate the influence factors of apathy. Results There were 34 cases of apathy in patient group (34.00%), which was significantly higher than those of control group (3 cases of apathy, 6.00%, P<0.001). The age, incidence of diabetes, NIHSS score, HAMD score, lesions in brain stem and multiple lesions were significantly higher in apathy group than that of non-apathy group, while educational level, MoCA score were significantly lower ( P<0.05). The Logistic regression analysis showed that the higher MoCA score was a protective factor for apathy, while higher NIHSS score, lesions in brain stem and multiple lesions were risk factors for the incidence apathy. Conclusion The cognitive impairment, severity of neurological deficits, brainstem lesions and multiple lesions may be the risk factors of apathy after the occurrence of acute ischemic stroke.
