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 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.

BACKGROUND:Knee osteoarthritis is prevalent among the middle-aged and senior people in Asian countries, however, the epidemiology survey of total knee arthroplasty is rarely reported in China.
OBJECTIVE: To retrospectively analyze the data of patients undergoing total knee arthroplasty from 2008 to 2013 in Hefei City, and explore the distribution of age and gender of these patients.
METHODS: A retrospective analysis among patients undergoing total knee arthroplasty from January 1st 2008 to December 31st 2013 in Hefei City was performed. Data were extracted from the database of Medical Records Room of Relevant Hospitals in Hefei City, including the patient’s gender, age, disease duration, education level, body mass index and surgical site. In addition, more clinical information in one hospital were selected and analyzed, to compare the difference of clinical features between men and women.
RESULTS AND CONCLUSION:From 2008 to 2013, totaly 1 146 patients underwent total knee arthroplasty due to knee osteoarthritis. The rate of total knee arthroplasty increased over the 6 years and was much higher in women than in men. The single-centre registry data revealed that there was no difference in age, disease duration, education level, and body mass index and surgical site between men and women. Our findings indicate that, the rate of total knee arthroplasty is increasing steadily from 2008 to 2013 in Hefei City and is higher in women than in men. Risk factors that account for such disparity in total knee arthroplasty utilization need to be further investigated.

Quantitative NMR (qNMR) is a technology based on the principle of NMR. This technology does not need the references of the determined components, which supplies a solution for the problem of reference scarcity in the quantitative analysis of traditional Chinese medicines. Moreover, this technology has the advantages of easy operation, non-destructiveness for the determined sample, high accuracy and repeatability, in comparison with HPLC, LC-MS and GC-MS. NMR technology has achieved quantum leap in sensitivity and accuracy with the development of NMR hardware. In addition, the choice of appropriate experimental parameters of the pre-treatment and measurement procedure as well as the post-acquisition processing is also important for obtaining high-quality and reproducible NMR spectra. This review summarizes the principle of qHNMR, the various experimental parameters affecting the accuracy and the precision of qHNMR, such as signal to noise ratio, relaxation delay, pulse width, acquisition time, window function, phase correction and baseline correction, and their corresponding optimized methods. Moreover, the application of qHNMR in the fields of quantitation of single or multi-components of traditional Chinese medicines, the purity detection of references, and the quality analysis of foods has been discussed. In addition, the existing questions and the future application prospects of qNMR in natural product areas are also presented.

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 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.
