OBJECTIVE To identify the possible risk factors for the development of surgical site infection (SSI). METHODS A total of 218 consecutive patients who received open cholecystectomy due to gallbladder disease and stone of common bile duct during from the Jun to Dec in 2007 were included in the study. The potential risk factors including clinical features,biochemical data,operative types and incision types were analyzed by univariate analysis. RESULTS The overall incidence of SSI was 5.04%.The incidence of SSI in cholecystectomy alone group was lower than in cholecystectomy with exploration of common bile duct group (10.9% vs 3.1%,P=0.022).The incidence of SSI in emergency group was higher than that in selective operation group (12.5% vs 3.8%,P=0.037). The incidence of SSI among patients with white blood cell count more than 10.0?109 befove surgery was higher (12.2% vs 3.0%,P=0.025). The incidence was 1.5%,6.1% and 26.3%,respectively,for patients with Ⅱ,Ⅲ and Ⅳ types incision (P=0.000). CONCLUSIONS These findings indicate that risk factors for the development of SSI after open cholecystectomy include operation manner,operation type,incision type and preoperative leucocyte count.

OBJECTIVE: To investigate the relationship between pure-tone average (PTA), the fractional anisotropy (FA) of the auditory pathway, cognitive cortex and auditory cortex in presbycusis. METHOD: Twenty-five elderly subjects with presbycusis were participated in the study. PTA, speech discrimination abilities were evaluated in each subject. Diffusion tensor imaging (DTI) was applied to access the FA of the IC, the superior frontal gyrus and the Heschl's gyrus. Compare the difference between two sides of the values of FA in the three areas. Bivariate correlation analysis was performed to evaluate the effects of PTA and FA of the inferior colliculus (IC), the superior frontal gyrus and the Heschl's gyrus on speech discrimination abilities. RESULT: There were no significant differences between the left and right side of the inferior colliculus (P > 0.05). Higher FA values were recorded at the left side of the Heschl's gyrus and the superior frontal gyrus (P < 0.05). Both PTA and the FA of the superior frontal gyrus have a negative association with speech discrimination abilities (P < 0.01, P < 0.05), while the FA of the Heschl's gyrus has a positive association with speech discrimination abilities (P < 0.05). CONCLUSION Our findings indicated that the speech discrimination abilities of the elderly is not only related to the peripheral auditory function, but also to the central auditory and cognitive function.

Sleep is a common physiological phenomenon of animals.We may have different kinds of sleep disorders in our daily life,such as difficulty falling asleep,insomnia,hypersomnia and changes of sleep patterns,etc.Pain is a subjective response of the body to stimuli of certain degrees.Sleep disorders are closely related to pain:pain can interfere with people's normal physiology and psychology conditions and affect individual's sleep;different kinds of sleep disorders can affect the body' s sensitivity to pain.The relationship between pain and sleep disorders has become one of the most common causality in clinical research.In this paper we summarizes the pathophysiological relation and mutual influence between pain and sleep disorders.

ObjectiveTo observe the change of blood phosphorus and N-terminal pro-brain natriuretic peptide(NT-proBNP) in patients with severe acute organophosphorus pesticide poisoning (AOPP)and explore their clinical significance.MethodsSeventy-eight severe AOPP patients were selected and divided into dead group (54 cases) and survival group (24 cases).NT-proBNP and blood phosphorus were examined when the patients were just hospitalized,and after 1,2,4 d and when they were turn out from ICU or before the patients dead.ResultsComparing with survival group,blood phosphorus and NT-proBNP of dead group had no significant difference when the patients were just hospitalized(P＞ 0.05 ).After 1,2 and 4d NT-proBNP of dead group [ ( 1986.5 ± 24.9),(3568.2 ± 56.9),(7829.0 ± 64.3 ) ng/L ]was higher than that of survival group [ ( 1068.4 ± 20.2),(986.6 ± 16.4),(943.7 ± 14.6) ng/L,P ＜ 0.05 or ＜ 0.01 ],while blood phosphorus was significant lower than that in survival group [ ( 1.22 ± 0.13 ),(0.81 ± 0.10),(0.58 ±0.07 ) mmol/L vs.( 1.53 ± 0.16),( 1.48 ± 0.13 ),( 1.46 ± 0.14 ) mmol/L,P ＜ 0.05 or ＜ 0.01 ].NT-proBNP of dead group increased and blood phosphorusreduced gradually by time extending (P ＜ 0.05).NT-proBNP was lower when patients were turn out from ICU than that when the patients were just hospitalized [ (327.5 ±12.3) ng/L vs. (1023.3 ± 18.8) ng/L,P ＜ 0.05].Blood phosphorus had no difference at all time points in survival group (P ＞ 0.05 ).NT-proBNP was higher [ ( 31 486.5 ± 120.7) ng/L vs.(327.5 ± 12.3) ng/L,P ＜0.01 ]and blood phosphorus was lower [ (0.24 ± 0.03 ) mmol/L vs.( 1.57 ± 0.15 ) mmol/L,P ＜ 0.01 ]before death in dead group compared with those at the time turning out from ICU in survival group.Conclusions The value of NT-proBNP increased and blood phosphorus reduced gradually with disease progression.NT-proBNP and blood phosphorus were important factors reflecting the prognosis of blood AOPP patients.

Objective To investigate the incidence of needle stick injuries of nursing students in different stages of clinical practice and occupational protective education to provide evidence for developing education strategies. Methods One hundred and forty-one nursing students were surveyed retrospectively by a self-designed questionnaire. Results A total of 75.9%(107/141) nursing students had been injured in clinical practice. The incidence of needle stick injuries varied in different stages of clinical practice. Compared with the middle and late stage of clinical practice, the incidence of needle stick injuries was highest in the early stage of clinical practice:53.9%(76/141) vs. 38.3%(54/141),7.8%(11/141),and there was significant difference, χ2=216.14, P<0.05.About 64.2%(88/141)-78.0%(110/141) nursing students had not received protective education on the needle stick injuries. Only 48.9%(69/141)-55.3%(78/141) of nursing students were given protective training on needle stick injuries in their practice hospitals. Before clinical practice, 63.1%(89/141) nursing students had not been vaccinated to prevent infective diseases. Conclusions To reduce the incidence of needle stick injuries and related potential risks of infection caused by injuries, it is necessary to strengthen pre-practice education on occupational protection among nursing students. Perfect supervision system should also be established in practice hospitals and clinic wards.

Affluent color Doppler flow signals of tumor were found in 11 patients (91.67%).Conclusion Ultrasonographic characteristics of dermatofibrosarcoma protuberans include distinct boundary, regular shape, heterogeneous hypoechogenicity and rich color Doppler flow signals without regional lymph node metastasis.

Objective To investigate the effect of electroacupuncture on serum insulin (INS) levels and gastric antral cholecystokinin (CCK) content in rats with diabetic gastroparesis (DGP).Methods Sixty SD rats were randomized into groups A, B, C, D and E, 12 rats each. Group A is a normal control. A DGP model was made by an intraperitoneal injection of 2% streptozocin (STZ) plus an irregular high sugar and fat diet in groups B, C, D and E. group B is a model one and did not receive treatment. Group C received electroacupuncture at points Zusanli, Sanyinjiao and Liangmen; group D, electroacupuncture at the control points of Zusanli, Sanyinjiao and Liangmen. Group C, an oral gavage of metoclopramide tablet solution. Blood sugar and urine sugar were determined using a OneTouch lood glucose meter and Tes-Tape, respectively. The gastric emptying rate and the intestinal migration rate were measured by an oral gavage of phenol red. Serum INS levels and gastric antral CCK content were measured by ELISA in every group of rats before and after treatment.Results There were statistically significant differences in blood and urine sugar values between group B, C, D or E rats and group A (P<0.01) and between group C rats and group B or E (P<0.05). There was a statistically significant difference in the gastric emptying rate between group B, C, D or E rats and group A (P<0.01) and between group C rats and group B or D (P<0.01,P<0.05). There was a statistically significant difference in the intestinal migration rate between group B or D rats and group A (P<0.01) and between group C rats and group B or D (P<0.01). There were statistically significant differences in serum INS levels and gastric antral CCK content between groups B and A rats (P<0.05,P<0.01). There was a statistically significant difference in gastric antral CCK content between groups D and A rats (P<0.01). There were statistically significant differences in serum INS levels and gastric antral CCK content between groups C or E rats and group B (P<0.05,P<0.01). There was a statistically significant difference in gastric antral CCK content between groups C and D rats (P<0.05).Conclusions Electroacupuncture can markedly improve gastrointestinal functions and promote gastric emptying in DGP rats. Its therapeutic effect may be related to electroacupuncture raising serum INS levels and reducing gastric antral CCK content.
