OBJECTIVE To investigate the prevention from hospital infection and therapy in fracture patients.METHODS We analyzed the situation of hospital infection in the fracture patients ranged from 2000 to 2005 with reviewing and perspective statistical method.RESULTS Totally 43 cases were infected from 1345 fracture patients,taken 3.2%.It was the highest with infection rate under the age of 5(6.0%),then was successively at the 15-44 years old age,5-14 years old age,≥60 and 45-59 years old age.CONCLUSIONS The fracture patients or those experiencing surgical operation are easy to have hospital infection.It is a multifactorial result.For instance,the environment of ward,the disinfection measure in operation,the skilled degree of surgical operators,the length of operation time,rational selection antibiotics and so on,are all the important factors to prevent and cure hospital infection.Pay attention to the quality controlling every link,can reduce the rate of hospital infection among fracture patients.

Objective To study the role of coping styles in the relationship between coping resources and psychosomatic health in patients with asthma. Methods 184 adult patients with asthma were investigated with General Serf-Efficacy Scale (GSES), Internality, Powerful Others, and Chance Scale (IPC), Social Support Rat-ing Scale (SSRS), Defensive Style Questionnaire (DSQ), Trait Coping Style Questionnaire (TCSQ) and Short Form 36 Health Survey Questionnaire (SF-36). Results Significant correlation between self-efficacy (r=0.356),locus of control(Ir=0.208, Pr=0.341, Cr=-0.349) ,subjective(r=0.201) and objective(r=0.189)social support, immature and middle ( r = - 0. 257 ) defensive styles and coping styles ( PCr = 0.231, NCr =-0.505 ) with Mental Component Summary (MCS) was found (all P <0.05), but Physical Component Summary (PCS) was only related to self-efficacy( r=0. 175) ,chance(r=0.150),immature(r=-0.256) and middle de-fensive Styles and negtive coping styles (all P < 0.05). PCS (t = - 5.189) and MCS (t = - 6. 758) could be predic-ted effectively by negative coping style (all P<0.01). Moreover, self-efficacy, powerful others and the use of so-cial support could had an effect on the health of patients through negative coping style. Conclusion Negative coping style could not only have a direct effect on the health of asthma patients but also be a mediator between self-efficacy, locus of control, social support and the health of patients.

Objective To investigate the changes of brain tissue in bilateral temporal lobes at different stages after nasopharyngeal carcinoma radiotherapy by diffusion tensor imaging(DTI)and 1H-MR spectroscopy(1H-MRS).Methods DTI and 1H-MRS were performed in 48 patients with nasopharyngeal carcinoma.in which conventional MRI revealed normal findings after radiotherapy.Twenty-four healthy controls were enrolled in this study and underwent the galne MR scanning.After the image processing and spectral analysis,apparent diffusion coefficient(ADC),fractional anisotropy(FA) and 3 eigenvalue λ1,λ2,λ3 of DTI and the NAA/Cho,NAA/Cr,Cho/Cr of 1H-MRS were measured in bilateral temporal lobes.Forty-eight NPC patients were divided into 3 groups [ less than 6 months(16 cases),6 to 12 months (6 cases)and more than 12 months(26 cases)after radiotherapy]according to different stages of radiationinduced injury of brain.each group's DTI and 1H-MRS data were measured respectively and one-way ANOVA was applied to analyze each parameter. Results The FA value of each test group(less than 6 months.6 to 12 months and more than 12 months)and the control group were 0.445±0.017,0.460±0.016,0.461±0.025,0.473±0.023 respectively.The ADC values of each group were(8.51±0.43)×10-4.(8.48±0.34)×10-4,(8.40±0.33)×10-4,(8.68±0.57)×10-4mm2/s respectively.And the maximum eigenvalue λ1 of each group were(1.251±0.065)× 10-3,(1.293±0.051)×10-3,(1.317±0.074)×10-3,(1.350±0.091)× 10-3mm2/s.The three indicators were significantly difrerent among groups(F=10.873,3.399,9.750 respectively,P<0.05).λ2,λ3 values showed no significant difference among the groups.The NAA/Cho of 1H-MRS of each groups were0.910±0.112,0.972±0.101,1.060±0.095,1.261±0.105 respectively,and the NAA/Cr were 1.212±0.236,1.208±0.183,1.228±0.236,1.435±0.225 respectively.Both of them had significant differences among groups(F=52.840,8.176 respectively,P<0.01).Cho/Cr showed no significant difference among the groups.Conclusions DTI combining with 1H-MRS play a certain guiding role on monitoring and evaluating of radiation injury of brain tissue in nasopharyngeal carcinoma after radiotherapy.It Can provide a scientific basis for the dynamic monitoring of radiation brain injury.

Objective To explore which method is more advantaged by comparing two kinds of tubular stomach in esophageal cancer operation and the occurrence of postoperative complications.Methods There were 47 esophageal cancer patients and they were randomly divided into two groups:A group including 24 patients and making mechanical clipping lesser curvature,B group including 23 patients and hand-sewn shrink lesser,and the major complications were analyzed and compared.Results All patients underwent radical tumor resection without the operative mortality.There was 1 patient of acute hemorrhagic of gastric resection margin in A group,and there was 1 patient of thoracic gastric leakage and 1 patient of anastomotic fistula in B group.In 12-month follow-up,there was 1 patient of anastomotic narrow in A group and 4 cases in B group (P ＞ 0.05).After 3,6 and 12 months,emptying dysfunction was not found by upper gastrointestinal imaging and CT,but the thoracic stomach expansion was found in two groups,and the degree of thoracic stomach expansion in B group was more serious than that in A group,the part of the thoracic stomach of 3 patients in B group protruding into the opposite chest.There was 1 patient with thoracic-gastro syndrome after eating in A group and 3 patients in B group (P ＞ 0.05).There were 3 patients with mild reflux esophagitis in A group and 10 patients with serious reflux esophagitis in B group (P＜0.05).Conclusion Comparing two operative methods,the mechanical clipping lesser curvature is more advantaged than hand-sewn shrink lesser.

Objective To assess the biophysical characteristics of normal skin and inflammatory skin lesions in mild and moderate acne. Methods Seventy-five mild and moderate acne vulgaris patients were included in the study. One inflammatory lesion measuring 2.0 to 5.0 mm in diameter which occurred within 48 hours prior to the measurement was selected as the target lesion. Trans-epidermis water loss (TEWL), capacitance and a* value were measured in target lesions and lesion-adjacent normal skin. Sebum content immediately,1 and 4 (saturated) hours after face washing was also determined on target lesions and central forehead between the eyebrows. Sebum secretion rate (SSR) was calculated. Results The TEWL and SSR significantly increased in the lesion-adjacent normal skin with the increment of inflammatory lesion number (both P < 0.05), and increased in target lesions with the elevation of a* value (both P < 0.05). The target lesions exhibited a significantly higher TEWL but a lower saturated sebum content and SSR than the adjacent normal skin did (all P <0.05). Conclusions The severity of inflammatory lesions is correlated with the impaired barrier function and increased SSR in facial skin. Compared with the adjacent normal skin, inflammatory skin lesions have a reduced skin barrier function and SSR.

Objective To study the etiology,pathogenesis,diagnosis and treatment of non-traumatic splenic rupture.Method The clinical data of patients with atraumatic splenic rupture from our hospital were retrospectively analyzed,and the liferatures were reviewed.Results Most cases were male.The average age was high.The etiological factors were diverse,and the most common being blood diseases,virus infection,local inflammation and neoplasm.The pathogenesis is related to splenomegaly,increase in splenic fragility,altered haemostatic mechanisms,malposition of the spleen,and violent contraction of the diaphragm.It is more difficult to arrive at a diagnosis when compared with traumatic splenic rupture.Most patients required splenectomy,especially when the etiological factors were malignant blood diseases or splenic tumors.Some patients received non-operative treatment.The prognosis was related to the etiological factors and age.Conclusions The etiological factors of non-traumatic splenic rupture were diverse,and pathological splenic rupture was most common.A preoperative diagnosis was difficult,and splenectomy was the most common treatment.
