Objective To investigate the prevalence of dyslipidemia and overweight/obesity of residents from different economic communities.Method One thousand six hundred and twenty-three residents from three communities with different economic condition in Huadu District,Guangzhou from June to July 2012 participated in the survey by questionnaire and health examination.Results The total prevalence rate in overweight/obesity was 29.4%and that of dyslipidemia 45.4%. The difference of prevalence rate of dyslipidemia among the three economic communities was not statistically significant(P>0.05). But the prevalence of overweight/obesity was statistically significantly different among them(P<0.05). The prevalence rate of overweight/obesity in Huadong town with a relatively poorer economy was lower than that of Tianmei town with a relatively better economy(P<0.017). The prevalence rate of overweight/obesity of male among the three communities had no significant differences(P>0.05),whereas the differences in the females were statistically significant(P<0.05),and the prevalence rate of Huadong town was lower than that of Tianmei town&Xinhua town. The differences in the prevalence of overweight/obesity at different ages from all economic communities showed statistical significance(all P<0.05).The residents aged 45~65 accounted for a large proportion of overweight/obesity.Conclusions Residents in the area have a high prevalence of overweight/obesity and dyslipidemia. The prevalence rates of overweight/obesity from the villages with better economic conditions are higher than that from the villages with poorer economic conditions. Residents aged 45-65 from all the three communities have a relatively high occurrence of overweight/obesity and dyslipidemia.

Objective To analyze the dynamic changes of white blood cells in patients with cavitary pulmonary tuberculosis (CPTB) during chemotherapy procedure ,and explore immunological indexes which could evaluate the curative effect and prognosis . Methods 85 cases of patients with CPTB (CPTB group) and 100 healthy people conducted physical examination (control group) were enrolled in this study ,The immunological indexes of white blood cells were detected and compared between CPTB group and control group ,and dynamic changes of white blood cells were analyzed in patients with CPTB .Results Compared with the control group ,absolute lymphocyte count and percentage of lymphocyte were decreased in the CPTB group before chemotherapy ,while the total white blood cells count ,absolute neutrophil count and percentage of neutrophil ,absolute monocyte count and percentage of monocyte were increased in the CPTB group before chemotherapy ,there were statistically significant differences between the two groups(P<0 .05) .Except the absolute lymphocyte count ,other indexes were statistically increased or decreased during chemothera‐py procedure .Conclusion After chemotherapy ,the immunological reactions induced by lymphocyte are under inhibitory state .The dynamic changes of white blood cells could reflect the state of cellular immunity in patients with CPTB during chemotherapy ,which could be helpful for the evaluation of curative effect and prognosis .

In vitro cellular adherence of murine neutrophils (Neu), macrophages (Mo) and eosinophils (Eos) to infective larvae (L3) of periodic Brugia malayi was promoted by immune serum (AIMS) or fresh normal mice serun (fNMS). Mo and Neu were more potent than Eos . in killing the L3. Eos could adhere to the L3 in the presence of AIMS or fNMS but a weak cy-totoxic effect was observed only when AIMS was used. The activity in AIMS could be removed with Staphylococcus aureus containing Protein-A (SPA) or anti-mice IgG antiserum suggesting that IgG might be in the observed cytotoxicity. Immunofluorescent staining revealed IgG binding to the surface of L3 after incubation with AIMS. Heat treatment of AIMS at 56℃ 30 min resulted in a reduced cytotoxic effect suggesting the role of complement in the reaction. EDTA but not EGTA abolished this activity indicating the operation of complement by alternate pathway. Scanning electron microscopic (SEM) studies comfirmed that the celluar adherence resulted in gross surface damage to the infective larvae.

[Objective]To explore the consumptive disease treating experience in Gushi Yijing, written by Gu Songyuan who lived in the Qing Dynasty. [Methods]By studying consumptive disease related content in the book, discussing and summing up the consumptive disease treating experience. [Results] On the basis of pointing out seven kinds of error method that doctor treating consumptive disease at that time, Gu Songyuan put forward the opinion that consumptive disease was usual y caused by the internal injury of Zang and Fu organs which resulted into Yin deficiency as the main pathogenesis. The article contained other details as fol ows: the basic symptoms of consumptive disease of the five internal organs, three main therapeutic methods on treatment of consumptive disease, the preference of nourishment combined drugs with food, habit of using some sweet and cold durgs which can clear heat, the use of flesh and blood of sentient beings and so on. So the key idea of this article focused on the method of nourishing Yin to enrich Jing and blood which could cure the consumptive disease effectively.[Conclusion]Gu Songyuan inherited predecessor ’s theory, analysed the etiology of consumptive disease of the five internal organs, pointed out Yin deficiency is the main pathogenesis, and then put forward the therapeutic method, which has some medical knowledge on modern clinic.

ObjectiveTo investigate the expression of psoriasin in actinic keratosis(AK),Bowen's disease and squamous cell carcinoma(SCC) tissues.MethodsImmunohistochemistry was carried out to quantify the expression of psoriasin protein in tissue specimens from the lesions of 20 patients with AK,25 patients with Bowen' s disease,21 patients with well differentiated SCC,and16 patients with poorly differentiated SCC,as well as from the skin of 18 normal human controls.ResultsThe expression rate of psoriasin was 11.1％ in the control specimens,significantly different from that in the AK(95.0％),Bowen's disease (88.0％),well differentiated SCC (95.2％),and poorly differentiated SCC (92.3％) specimens (all P ＜0.01 ).Psoriasin was expressed in the cytoplasm of keratinocytes and dyskeratotic keratinocytes in stratum corneum and upper 1 to 3 layers of stratum spinosums in AK tissue,in the cytoplasm of keratinocytes as well as the membrane and cytoplasm of vacuolated cells in all layers of the epidermis in Bowen's disease tissue.In well differentiated SCC,cornified pearl and dyskeratotic keratinocytes located in the stratum comeum and all layers of the stratum spinosums stained positive for psoriasin,and in poorly differentiated SCC,psoriasin was distributed in the stratum corneum and upper 1 to 5 layers of the stratum spinosums,but absent in poorly differentiated squamous cells.The expression intensity of psoriasin in tissues sequentially increased from AK,Bowen's disease to well differentiated SCC.Though the expression intensity of psoriasin in poorly differentiated SCC decreased,but was still higher than that in normal skin tissue(P ＜ 0.05).ConclusionPsoriasin is abnormally expressed in skin disorders with dysdifferentiation of squamous cells.

Objective To explore the risk factors of adhesive small bowel obstruction for the influence of the long-term therapeutic effects.Methods 218 case of adhesive small bowel obstruction in patients were treeted with a long follow-up and retrospective analysis.Results Among the 218 admissions in 235 patients,192 admissions (81.7.％) were surgical treated and 43 admissions(18.3％) were performed conservative treatment.The mean recovery time was 65.7 months and the accumulative incidence of surgical recurrence in 5 years was 19.0％ in surgical group and those in conservative group were 50.4 months and 34.0％ respectively.There was significant difference between two groups (P ＜ 0.05).Conclusion The long-term efficacy of risk factors was related to the treatment before the operation site and times,the last operation to the incidence of admissions.No other independent risk factor of recurrence was found.Surgical treatment serves as a better way in the prevention of later recurrences in patients with adhesive intestinal obstruction under certain conditions.

The main teaching methods for medical students and residents are didactic teaching,rote learning and apprenticeship.Although these teaching methods can be good for imparting knowledge,they are obviously insufficient for the training of technical skills,team cooperation and complex decision making.Application of biomedical engineering simulation in the anesthesia teaching can partially compensate for the insufficiency.The progress of biomedical engineering simulation in anesthesia teaching is reviewed and the educational trend was explored.

Objective To study the value of HEART scores in predicting the risk of getting acute coronary syndrome in patients with chest pain and assessing the prognosis in order to elucidate the validity of the HEART scores.Methods A total of 1 200 patients with chest pain were continuously observed and followed up,and their HEART scores were calculated.The survival rates were calculated with Kaplan-Meier method and AUROC (area under ROC curve) was used to determine the accuracy of this methods.The HEART scores were compared with TIMI and GRACE scores.Results Low HEART scores (0-3) were found in 34.5％ of the patients and MACE (major adverse cardiac event) occurred in 1.4％ of them.The patients with intermediate HEART scores (4-6) accounted for 50.7％ patients,and MACE was diagnosed in 22.2％ of them.High HEART scores (7-10) were found in 14.85％ patients,and MACE occurred in 60.7％ of them.There was significant difference among these three groups (Log rank P ＜ 0.01).The AUROC of HEART score was 0.83 (95％ CI:0.80-0.85,P ＜0.01),being significantly higher than the GRACE scores (0.76) and TIMI scores (0.72).Conclusions The HEART score is applicable for predicting the risk of getting acute coronary syndrome of chest pain patients in emergency department and the prognosis.

Objective To explore propofol dosage difference between in morning and at after-noon undergoing gynecological clinic short operation.Methods One thousands and nine hundred fifty eight female patients,aged 1 6-50 yr,of ASA physical status Ior II,undergoing gynecology clinic short operation,according to the operation time,were divided into two groups,Group morning (8:30-1 1:30,n =1047)and group afternoon (14:00-1 7:00,n =91 1).Each patient was intravenously injected fentanyl 0.01 μg/kg,and then propofol 2.5 mg/kg.When the observer’s assessment of alertness/se-dation (OAA/S)scores reached 0 score,the operation began.If the body moved,the surgery was stopped and 25 mg propofol was intravenously injected quickly.After 10 seconds observation,if the body movement existed,25 mg more propofol was performed,until the movement disappeared.Re-cord patients’year,height,weight,body mass index,and the heart beat,blood pressure of pre-op-eration,the number of times of cervix uteri expansion per vagina,the history of labor per vagina,the total dosage of propofol and the time length of sedation.Results The dosage of group afternoon (1 52.1 6±65.90)mg was higher than group morning’s (135.69±37.67)mg (P <0.05).There was no significant difference of time lengths of sedation between the two groups.Additional use of propofol in the afternoon group 387 (42.5%)was higher than group morning’s 1 99 (23.5%)(P <0.05).Conclusion In gynecological clinic short operation,the propofol dosage in afternoon was higher than that in the morning group.But the sedation time length in afternoon was not longer than that in the morning.
