Objective To explore the prevalence of depression in diabetes foot ulcer patients , and to an-alyze the correlation between depression morbidity and various factors such as age , HbA1c level, and quality of life etc.Methods 73 diabetes foot ulcer patients admitted from Sep .2012 to Sep.2014 were enrolled.Depres-sion was assessed using the 9-item patient health questionnaire (PHQ-9).Data such as the age, sex, duration of diabetes and foot ulcer , HbA1C level, smoking were recorded .The severity of foot ulcer was evaluated by Wagner's classification.The quality of life was scored by short form(SF-36)health survey questionnaire.Results The morbidity of depression in diabetes foot ulcer patients was 49.3%in total and 17.8% in the moderate to severe depression group .The prevalence in patients with HbA 1c≥7.0%was significantly higher than that in pa-tients with HbA1c<7.0%(66% vs 35%,P<0.01).Higher occurance of HbA1c≥7.0% was found in the moderate to severe depression group compared to that in the mild depression group .The prevalence of depression was 39.1%in grade 1 in wagner classification , 48.6% in grade 2 to 3 in wagner classification and 69.2% in grade 4 to 5 in wagner classification , showing the two was positively correlated .When duration of foot ulcer lasted more than 6 months, the morbidity of depression(58.1%)was significantly increased(P<0.05).The quality of life was significantly declined in patients with depression by SF-36 questionnaire ( P<0.05 ) .No association was found between the depression morbidity and the age , duration of diabetes , amount of complications or smoking (P>0.05).Conclusions This study shows a high prevalence of depression symptom in diabetes foot ulcer pa -tients.Depression is associated with HbA1c level, the extent and duration of foot ulcer .

[Objective] To investigate and discuss if there are special syndromes,same disease but different syndromes and same syndrome but different diseases in the different gastric ulcer rat models.[Methods] Based on reports,we select fourmethods-stress,antifani,apoplon,and alcohol to make gastric ulcer model simultaneously,and set up the normal and control groups.Then we use the standardized and quantified four diagnostics and differentiation methods for mice,which are established to examine and appraise the above models in an objective,dynamic and quantified way.[Result] First,different mice models have different syndromes,such as in the water immersion model,damage to Qi blood Yin and Yang was slight and recovered quickly.The anti-fani model,with typical syndromes of cold in the stomach,is a compound model of Qi,blood,Yin and Yang deficiency;second,there exists syndrome evolution in the disease diversity stage in the same rat;moreover,significant syndrome difference exists for the same disease in different rat.For example,on the second day after the alcohol was given to the rats,there was Yin deficiency,or abundance of Qi,or deficiency in both Yin and Yang to the different individual.Thirdly,as for same syndrome but different disease,similar syndromes appear on the same stage in different diseases,as well as the similar syndrome appear on the different stage in different diseases.For instance,the anti-fani model and the apoplon model have similar syndromes of cold in the stomach,Qi deficiency,Yin and Yang deficiency.[Conclusion] There exist respective syndromes in different gastric ulcer mice models.We can infer that to put into practice"treating the same disease with different methods"and"treating different diseases with same method"will help improve the curative effect.

ObjectiveTo collect and analyze patients' evaluation of basic medical services in Tianjin community health service institutions and to suggest improvements.MethodsA total of 15 community health service centers and 15 community health service stations in six urban districts of Tianjin were selected by stratified sampling and 300 randomly intercepted patients were surveyed by questionnaire.ResultsApproximately half ( 157/300, 52. 3％ ) the patients selected community health service institution as their first choice to seek medical attention. The most important reason for this, with 89.2％ patients responding yes, was that the community health service institution was close to home and very convenient.One quarter (79/300, 25.3％ ) of the patients regularly consulted the same doctor and 17.7％ (53/300)seldom went to see a doctor. The proportion of patients expressing a high degree of satisfaction to service standards and health professionals was 78. 7％, of which satisfaction with physicians' explanation about the patients' illness ranked highest at 83. 7％ (251/300). Patients' confidence level of doctors' diagnosis,physical examination, and auxiliary examination was 92. 0％. Moreover, most (87. 0％ ) patients reported that doctors communicate well with them; 85.0％ (255/300) patients received health instruction from doctors during visits, and 82. 0％ patients reported that doctors pay attention to protecting patients' privacy.The overall satisfaction of patients to environmental facilities and process management of community health service institutions was 73.6％. On the other hand, patient satisfaction with medicine types, service price,instrumentation and equipment, and environment were all lower than the average satisfaction. Conclusions Patients were basically satisfied with medical service in community health service institutions. Three main problem areas were identified: patients' use of community health services is deficient, medical service ability is partially lacking, and the service feature of general practitioners (GPs) is not obvious. Improvements of basic medical service ability in the community, cultivation of GPs, and basic medicine regulation are advocated.

Objective To compare the efficacy of and adverse reactions to a fractional micro-plasma radio-frequency technology versus fractional ultrapulsed CO2 laser in the treatment of atrophic acne scars.Methods Twenty-one patients with atrophic acne scars were enrolled in this study.Half of each subject's face was treated with micro-plasma,and the other half with fractional ultrapulsed CO2 laser,for one session.Treatments were randomly administered in a split-face manner.The efficacy and adverse effects were evaluated 6 months after the treatment by using the following outcome parameters:ECCA grading scale (échelle d' évaluation clinique des cicatrices d'acné),degrees of post-treatment pain and edema,time taken for crusting and durations of inflammatory erythema,patients' subjective rating of improvement in scar by using a quartile grading scale.A non-parametric rank test was conducted to compare the efficacy and adverse effects between the two treatments.A scar model was established on both ears of a New Zealand big ear rabbit,and treated with the CO2 laser and micro-plasma respectively,immediately followed by the resection of scar tissue for the observation of histological changes.Results A decrease of ECCAscore was observed in 90.5％ (19/21) of the patients after micro-plasma treatment,and in 86.7％ (18/21) after CO2 laser treatment; no significant difference was observed in the response rate (P ＞ 0.05).In detail,ECCA score decreased by 31.5％ (from 50.71 to 34.76 ) after micro-plasma treatment,compared to 29.9％ (from 53.57 to 38.10) after CO2 laser treatmet.Mild edema was observed after micro-plasma treatment,with the duration of erythema and crusting being 13.95 days and 6.95 days,respectively,compared to 45.81 days and 10.10 days respectively,after CO2 laser treatment.Pigmentation occurred in none of the patients after micro-plasma treatment,but in 19％ after CO2 laser treatment.Animal experiment showed that microscopic ablation zones were broad and shallow after micro-plasma treatment,but narrow and deep after CO2 laser treatment.Conclusions Fractional micro-plasma and CO2 laser are both effective for the treatment of atrophic acne scars,but the former seems to have less side effects with a lower incidence of pigmentation.

To study the expression of the bFGF and its receptor in the mouse bone marrow by treatment with acute radioactive injury and Ligustrazine, 56 mice were divided into 3 groups: normal group, radiation-injured group and Ligustrazine group. After irradiation by 6.0 Gy 60Co gamma-ray, each mouse was orally given 0.1 ml Ligustrazine twice a day for 13 days in Ligustrazine group, and each mouse in radiation injured group was orally given equal amount of saline. On the 3rd, 7th, 14th day after irradiation, bone marrow mono-nuclear cells (BMMNC) were counted, and the expression levels of bPGF and bFGFR in bone marrow were evaluated by immunohistochemistry and flow cytometry analysis respectively. On the 3rd, 7th, 14th day after irradiation, expression of bFGF in bone marrow were significantly lower than in normal group (P<0.05 or P<0.01). Expressions of bFGF and bFGFR were much higher in Ligustrazine treated group than that in the control group (P<0.05 or P<0.01). Ligustrazine potentiate the expression of bFGF and bFGFR in bone marrow MNC to recover the bone marrow hematopoiesis inductive microenvironment, which is one of the mechanisms by which Ligustrazine rebuild the bone marrow hematopoiesis after acute radioactive injury.

The transfection efficiency of oligonucleotide and plasmid to the HL-60 cell line with lipofectaminePLUS was compared through observing the transfection rate and the expression duration of exogenous gene in the target cells. The results showed that the transfection rate of oligonucleotide to the HL-60 was about 90% - 95% and it had no obvious attenuation within 84 h. However, the plasmid transfection rate was only 5% -25% and it was decreased significantly within 60 h. It was suggested that the transfection of oligonucleotide with liposomes was better than that of plasmid.

Background and purpose: It has been reported that activation of Notch1 could strongly inhibit proliferation of HPV (human papilloma virus)-positive HeLa cells by down-regulation of the E6 and E7 genes. The aim of this paper was to investigate the role of the Notch signaling pathway in growth arrest of EC109 cells in vitro and the molecular mechanism. Methods: EC109 cell lines, a well differentiated human ESCC (esophageal squamous cell carcinoma) cell line with HPV18-positive, was used in the study. Exogenous intracellular domain of Notch1(ICN) was transfected into cultured EC109 cells by lipofectamine transfection, the proliferation of the transfected cells was measured by an MTT assay. Cell cycle distribution was analyzed by flow cytometry. Human papilloma virus type 18 (HPV18) E6/E7 mRNA expression was detected by RT-PCR, and p53 protein expression was detected by Western blot.Results: Activation of Notchl signaling resulted in inhibition of EC109 cell proliferation with the induction of G_2/ M arrest. There was a significant difference in terms of the percentage of G_2/M phase cells among the ICN-transfected group (42.57±1.57)% and the non-transfected group (1.88±0.66)% or the empty plasmid transfected group (1.99±1.02)% (P<0.01). Down modulation of HPV18 E6/E7 gene expression and upregulation of p53 expression was (2.15±0.23) in ICN-transfected group higher than non- transfected group (0.45±0.07) and empty plasmid transfected group (0.46±0.02) (P<0.01). Conclusion: Repression of HPV18 E6/E7 expression by Notch1 signaling results in growth suppression of HPV18-positive EC109 cells with concomitant activation of p53-mediated pathways.
