Objective To constitute a database of chronic wounds for characterizing the patients with chronic wounds.Methods Based on the guideline of chronic wounds defined by international wound healing society,86 outpatients with chronic wounds were selected between January and October in 2013 to set up a wound database using the wound information management system.The parameters including etiology,age distribution,mean time of fracture healing and wound healing time posterior to different treatments were analyzed.Results (1) Statistical difference existed for cause distribution (P ＜0.05).Top three causes were trauma (29％),varicosity (26％) and pressure sore (19％).(2) Age distribution varied significantly among the patients with various causes of chronic wounds (P ＜ 0.05).(3) Statistical difference was observed in healing time of various types of chronic wounds (P ＜ 0.05).Diabetic wound and varicose ulcer took the longest healing time,with average 116.36 days and 88.48 days respectively.(4) Patients treated with novel dressings had shorter healing time than those managed with traditional dressings (P ＜ 0.05).Conclusions Trauma,varicosity and pressure ulcer are relatively common among the outpatients.Etiology of chronic wounds is strongly related to age and novel dressings contributed to a shortened cause of the disorder.

Objective To investigate the proportion of streptococus pneumonia(SP), haemophilus influenzae (Hi),branhamella catarrhalis (BC), chlamydia pneumonia (CP) and mycoplasma pneumonia (MP) in children with acute pneumonia.Methods Fifty-three hospital-treated children with acute pneumofmonia were included in a prospective study. The enzyme immunoassay was used to detect antibodies in paired sera against non-capsulated Hi, Hi type-B capsular polysaccharide and whole cell, antibodies against pneumococcal pneumolysin, C-polysaccharide and pneumococcal pneumolysin, C-polysaccharide, surface protein A in circulating immune complexes and antibodies against BC and MP. Antibodies against CP by immunofluorescence in paired sera as well as blood cultures were detected in these cases.Results The evidence of bacteria infection was demonstrated in 32 cases (60.4 %) among children with acute pneumonia, of which 11 cases had 2 or 3 organisms coinfection. In these causative agents,SP and CP were the most common organisms (11/53 cases respectively,20.8 %), followed by MP (7/42,16.7 %),Hi(7/53,13.2 %).Conclusion SP,Hi,CP and MP are common causative agents of children with acute pneumonia and multi-agents coinfection isn′t ingnored in our empiric antibiotic therapy for the disease.

Objective To explore the association between psychiatric disorders and socioeconomic status such as education,income,employment and area of community settings in Zhejiang province.Methods Data were from the epidemiological survey of mental illnesses aged 15 and older in 2001(n=14 632).Psychiatric disorders were measured by GHQ-12 with a cut-point 4.Logistic multilevel analysis was the main statistical method being used.Results The overall prevalence of psychiatric disorders was 18.5%(95% confidence intervals,17.9% to 19.1%),higher than the data from Hebei province(u=4.39,P＜0.001).Annual household income and employment were strongly associated with psychiatric disorders especially for those with low income(odds ratio 3.45,95%CI:1.72-6.67)and unemployment(odds ratio 2.03,95%CI:1.73-2.40).Factors as regional effect and education level showed weak or inconsistent association with psychiatric disorders after controlling on other indicators.Conclusion Inverse gradient relation between psychiatric disorders and SES seemed as the main result of low SES individual characteristics and some minor effects at the county level.

Objective To investigate the expression of osteopontin and matrix metalloproteinase-9 (MMP9),and the relationship of osteopontin and MMP9 in malignant melanoma.Methods Expression of osteopontin and MMP9 was measured by immunohistochemical SP method in 23 patients with primary cuta- neous malignant melanoma,17 patients with metastatic melanoma and 20 patients with pigmented nevus. Results Osteopontin and MMP9 were expressed respectively in 87.5% and 75.0% of 40 malignant melanoma specimens,15.0% and 10.0% of 20 pigmented nevus specimens.The expression of both osteo- pontin and MMP9 was significantly higher (both P＜0.05) in malignant melanoma than in pigmented ne- vus.There was no correlation between the expression of osteopontin and MMP9,with age,sex,lymph node metastasis or location of lesions (P＞0.05).Twenty-nine cases were positive for both osteopontin and MMP9,4 negative for either osteopontin or MMP9.Conclusion Both osteopontin and MMP9 were over- expressed in malignant melanoma,but neither was related to lymph node metastasis.

Objective:To observe the effect of liver-soothing and mind-regulating acupuncture method on the resting-state electroencephalography (EEG) in rats with post-traumatic stress disorder (PTSD),and to provide evidence for the effect mechanism study and clinical application of acupuncture intervention for PTSD.Methods:Sixty Sprague-Dawley (SD) rats were randomly divided into a blank control group,a model group,a grasping group,a paroxetine group and an acupuncture group,with 12 rats in each group.Except for rats in the blank control group,rats in the other groups were subjected to preparing the PTSD models using 'incarceration plus electric shock' method.After interventions,changes in rat behavior of each group were observed;changes in resting-state EEG were collected and analyzed with multichannel EEG acquisition and analysis system,and image analysis and statistical processing were performed.Results:Compared with the blank control group,the average escape latency in the model group was significantly longer (P＜0.05),and the times of crossing the platform and the effective areas were all significantly reduced (P＜0.01).Compared with the grasping group,the average escape latencies in the paroxetine group and acupuncture group were significantly shortened (P＜0.05),and the times of crossing the platform and the effective areas were all significantly increased (P＜0.05).There were no significant differences in the average escape latency,the times of crossing the platform and the effective areas between the acupuncture group and paroxetine group (all P＞0.05).Compared with the blank control group,the α-wave power spectrum value in the model group was significantly decreased,and the power spectrum values of β-wave,δ-wave and a-wave were significantly increased (all P＜0.01);compared with the grasping group,α-wave power spectrum values in the paroxetine group and acupuncture group were significantly increased (both P＜0.01),and the power spectrum values of β-wave,δ-wave and a-wave were decreased significantly (all P＜0.01).The power spectrum values of α-wave,β-wave,δ-wave and (e)-wave of rats in the acupuncture group were not significantly different from those in the paroxetine group (all P＞0.05).Conclusion:Liver-soothing and mind-regulating acupuncture method can significantly improve the abnormal EEG activity in PTSD rats,which may be one mechanism of liver-soothing and mind-regulating acupuncture method in effectively affecting the brain function in PTSD rats.

Objective:To explore the relationship among psychological distress,adult attachment,and social support in primary caregivers of cancer patients.Methods:A total of 208 primary caregivers of cancer patients in one third grade hospital in Anhui Province were recruited.The 10-item Kessler Psychological Distress Scale(K10),Experiences in Close Relationships Inventory(ECR) and Social Support Questionnaire(SSQ) were used to explore psychological distress,adult attachment,and social support status.Results:The average K10 score was (21.5 ± 7.5).Multiple linear regression analysis indicated that caregiver gender,pressure on patient care,and attachment anxiety had positive prediction on psychological distress (β =2.30,3.02,0.13),while residence had negative prediction on psychological distress (β =-3.22).Conclusion:It suggests that the psychological distress is related to attachment anxiety and social support among the primary caregivers.

The feasibility of simultaneously loading both liposoluble and water-soluble components of Salvia miltiorrhiza in emulsion was discussed, in order to provide new ideas in comprehensive application of effective components in S. miltiorrhiza in terms of technology of pharmaceutics. With tanshinone II (A) and salvianolic acid B as raw materials, soybean phospholipid and poloxamer 188 as emulsifiers, and glycerin as isoosmotic regulator, the central composite design-response surface method was employed to optimize the prescription. The coarse emulsion was prepared with the high-speed shearing method and then homogenized in the high pressure homogenizer. The biphasic drug-loading intravenous emulsion was prepared to investigate its pharmaceutical properties and stability. The prepared emulsion is orange-yellow, with the average diameter of 241 nm and Zeta potential of -35.3 mV. Specifically, the drug loading capacity of tanshinone II (A) and salvianolic acid B were 0.5 g x L(-1) and 1 g x L(-1), respectively, with a good stability among long-term retention samples. According to the results, the prepared emulsion could load liposoluble tanshinone II (A) and water-soluble salvianolic acid B simultaneously, which lays a pharmaceutical foundation for giving full play to the efficacy of S. miltiorrhiza.

Objective To explore the factors influencing the premarital medical examination in Chinese population and to discuss the related possible intervention strategies.Methods Data were collected through self-designed questionnaires on 2572 newly married respondents,selected under a stratified randomized sampling method,at Marriage Registration Office in 12 counties in Zhejiang province.Predictive factors were derived from the integrating complementary constructs of Health Belief Model,Theory of Reasoned Action as well as individual demographic characteristics.Multiple logistic multilevel analyses was used as the main statistical method,with individuals as the ' low' and counties as the 'high' levels.Results Behaviors on premarital medical examination showed a clustering trait at the county level (P=0.018) and variance partition coefficients (VPC) of each variables was between 15.40％ and 17.58％.There were no statistical significances found in the rates of premarital medical examination among gender,age,residence of Household Registration,education,income,health insurance and history of premarital medical examination.However,significant correlation was seen on occupation of the respondents.The rate of premarital medical examination among the respondents who had not attended medical examination during the last six moths was 1.31times (95％ confidence intervals,1.05 -1.65 ) more than those who had,with OR (odds ratio) as 1.51 (95％CI:1.14-2.00) for the pregnant respondents in their first marriage and 0.35 (95％CI:0.23-0.51 )for remarried respondents,compared with women at first marriage but remained unpregnant.Regarding premarital medical examination,the respondents reported greater benefits,less barriers,greater positive behavioral attitudes and normative beliefs to it,with an ORs as 2.32 (95％ CI:1.18-4.60),0.71 (95％CI:0.57-0.90),1.69 (95％CI:1.10-2.58) and 1.72 (95％CI:1.34-2.20)respectively,but with no significant association with perceived susceptibility,perceived severity and motivation to comply.Conclusion Factors such as individual perceived benefits,barriers,attitudes and normative beliefs etc.,were determinants of premarital medical examination accompanied by minor (16％) influence coming from the geographical environment.

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.

RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).

CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.
