ObjectiveTo explore the effect of age on clinical outcomes of patients with massive infarction after decompressive craniectomy.MethodsClinical data of 103-sufferers,who have been operated by decompressive craniectomy in our hospital from January 1999 to January 2010 were summarized.Based on age,these data are divided into the research group( ≥60 years old,number =48) and the control group( ＜ 60 years old,number =55 ).Then two groups were studied and discussed by mortality,the ratio of postoperative complications and cases of preoperative comorbidities.ResultsComparing with the control group,it was evident that patients of the research group had higher mortality and ratio of postoperative complications,and moat of them suffered from preoperative manifold comorbidities ( x2 =11.097,24.915,14.404,all P ＜ 0.01 ).Besides,the percentage of patients with good prognosis was significantly lower( x2 =9.821,P ＜ 0.01 ).ConclusionPostoperative clinical outcomes of aged patients with the massive infarction were affected by preoperative manifold comorbidities and postoperative complications.However,younger patients could correspondingly achieve the preferable treatment effect after surgery.Hence,age should possess an imporrant impact for clinical outcomes of patients with massive cerebral infarction after decompressive craniectomy.

OBJECTIVE To analyze the occurring characteristic and curing measures of hospital infection for inpatients in the departments of neurology.METHODS The data of hospital infection for the medical records of 22 936 inpatients with disease in the departments of neurology of 40 hospitals in Anhui from Jan 2005 to Mar 2006 were analyzed.RESULTS Among all inpatients 1 011 were infected.The rate of infection was 4.41%.The infection distribution is described as follows:640 patients were infected in respiratory tract(63.30%);181 patients in urinary tract(17.90%),84 patients in gastrointestinal tract(8.31%);and 16 patients were in cutis tissue(1.58%).CONCLUSIONS Through performing aseptic manipulation strictly,curing underlying diseases,paying attention to aseptic manipulation and making the rational use of antimicrobial agents,the infection rate could be lowered.

Objective To investigate the effects of butylphthalide injection on serum levels of inflammatory factors and oxidative stress products in patients with acute cerebral infarction. Methods A total of 120 patients with acute cerebral infarction were selected in our hospital from March 2014 to September 2016. Patients were divided into conventional treatment group (n=56) and butylphthalide group (n=64) according the therapeutic methods. The conventional treatment group was treated with improving microcirculation and resisting blood platelet aggregation, while the butylphthalide group was injected with butylphthalide (100 mL intravenous drip, twice a day) on the basis of conventional treatment. The levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-17, IL-23 and methane dicarboxylic aldehyde (MDA) were detected before the treatment and 7 days,14 days after the treatment. The clinical efficacy was also accessed. Results The TNF-α, IL-6, IL-17, IL-23 and MDA levels were significantly decreased 7 days and 14 days after the treatment than those before the treatment in two groups of patients (P<0.05). And the above indexes were also decreased in butylphthalide group than those of conventional treatment group (P < 0.05). No obvious adverse reactions were observed in two groups. Conclusion Butylphthalide can improve the clinical symptoms through the inhibition of inflammation and oxidative stress in patients with acute cerebral infarction.

Objective To detect beta-human papilloma virus (HPV) and determine its genotype in actinic keratosis (AK) lesions.Methods Tissue specimens were collected from the lesions of 39 patients with AK and normal skin of 40 healthy controls.A nested PCR was performed to detect alpha-HPV and beta-HPV DNA in these specimens.The genotype of beta-HPV was determined in beta-HPV DNA-positive specimens by a common PCR using specific primers targeting 12 HPV genotypes,including HPV 5,8,15,17,19,20,21,23,36,38,49 and 80.Results The detection rate of beta-HPV DNA was 84.6％ (30/39) in the patients with AK,and 30.0％ (12/40) in the healthy controls (x2 =6.76,P ＜ 0.05),while no significant difference was observed in the detection rate of alpha-HPV DNA between the two groups (12.8％ vs.7.5％,x2 =0.91,P ＞ 0.05).HPV 38 was the predominant genotype of beta-HPV in these patients with a detection rate of 36％ (12/33),followed by HPV36.The prevalence of all the 12 genotypes of HPV was consistently low in the healthy controls.Mixed HPV infections were observed in 10 AK lesions,but in none of the healthy controls.No statistical difference was noted in the positivity rate of beta-HPV among patients at different ages,of different genders,with different occupations or clinical courses (x2 =0.53,0.94,0.81,0.73,respectively,all P ＞ 0.05).Conclusions Compared with healthy controls,the patients with AK showed a higher beta-HPV infection rate,with HPV38 as the predominant genotype.

Objective To definite the correlation of hip muscle density with proximal femoral fracture in the elderly.Methods The study included 41 proximal femoral fracture cases [14 males and 27 females,at age of (64.1 ±5.1)years] and 14 normal cases [4 males and 10 females,at age of (64.8 ± 3.9) years] that underwent CT examination for hip joint.In fracture group,19 cases sustained femoral neck fracture and 22 intertrochanteric fracture.CT imaging data were reviewed to analyze the correlation of age with hip muscle density at the level of ischium tubercle.Hip muscle density was compared between fracture side and healthy side in fracture group and between control group and fracture group.Results Hip muscle density showed a downward trend with increased age (P ＜ 0.05).Hip muscle density did not differ significantly between fracture side and healthy side in fracture group (P ＞ 0.05).Regardless of age,gender and other factors,hip anterior muscle density [(34.8 ± 4.1) Hu] and posterior muscle density [(22.1 ±5.5) Hu] were lower in fracture group than in control group [(44.4 ±5.7)Hu,(39.2 ±5.3)Hu respectively,P ＜ 0.05] but there was no significant difference in hip medial muscle density between the two groups (P ＞ 0.05).Conclusions Hip muscle density decreases with age and has no strong correlation with fracture.Deadline of the hip muscle density may be a risk factor to proximal femoral fracture in the elderly.

OBJECTIVE To know the basic situation of nosocomial infection control and management in all levels of hospitals in Anhui Province,and provide the theory basis for the future work.METHODS To investigate the students participating in the nosocomial infection management training class by using the questionnaire.RESULTS There were altogether 273 people from 217 hospitals accepting the investigation.From 217 hospitals there were 46 1st grade hospitals and 160 2nd grade hospitals and 11 third graed hospitals.In all the people engaged in the nosocomial infection management,83.88% were the females and 67.03% for nursing staff,the age of 30-50 years old was 79.84%,the middle professional rank accounted for 72.53%,and 79.86% people′s record of formal schooling was the technical college and below.CONCLUSIONS The basic situation of nosocomial infection management in majority hospitals of our Province is good,but in some hospitals,the function of the structure has not certainly obtained the full display.In order to adapt the development of the nosocomial infection supervisory work,promote it to be more perfect,personnel structure,resources arrangement,and administrative offices function should give enough reconstruction and construction.

OBJECTIVE To investigate the surgical site infection(SSI)in clean surgical sites and the perioperative antibiotic usage.METHODS The incidence of SSI and the antibiotics usages in 842 cases during perioperative were analyzed retrospectively in 32 hospitals.RESULTS One case with nosocomial infection was found(0.12%).The use rate of antibiotics was 98.57%.Among 802 cases using prophylactic antibiotics,the antibiotics were given in 181 cases thirty minutes to two hours before operation.136 cases were given 24 h before operation.And 485 cases were given after operation;195 cases stopped using antibiotics after 24 h,472 cases stopped using antibiotics after 4-6 days and 135 cases stopped to use antibiotics after 7 days.CONCLUSIONS The major problem is excessive use of antibiotic in clean surgical site during perioperation,long duration of antibiotics prophylaxis,more expensive antibiotics and unnecessary combination of antibiotics,suggesting that it be important to strengthen the management of antibiotics.
