AIM:To investigate the effect of microRNA ( miR)-193b on doxorubicin therapy in breast cancer in vitro.METHODS:miR-193b level in plasma was detected by real-time PCR in the patients with breast cancer or the healthy controls.MTT assay was performed to measure the inhibitory effect of miR-193b plus doxorubicin on the growth of MDA-MB-231 cells.Bioinformatics, real-time PCR and Western blot were performed to determine whether the expression of Mcl-1 was regulated by miR-193b.Mcl-1 expression vector was constructed , and the role of Mcl-1 vector toward miR-193b plus doxorubicin-induced cytotoxicity in MDA-MB-231 cells was observed by MTT assay .RESULTS:Down-regulation of miR-193b was found in breast cancer patients .The miR-193b plus doxorubicin group showed a higher growth inhibition than cisplation group in MDA-MB-231 cells.The expression of Mcl-1 at both mRNA and protein levels was down-regulated after miR-193b transfection.The growth inhibition of MDA-MB-231 cells treated with miR-193b plus doxorubicin was sig-nificantly decreased after the transfection of Mcl-1 expression vector.CONCLUSION: miR-193b sensitizes doxorubicin-induced cytotoxicity by targeting Mcl-1 in breast cancer .

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

Objective To investigate the effect of insulin resistance(IR) on the persons with abnormal blood glucose who underwent dietary interventions.Methods 194 individuals with abnormal blood glucose were selected from hyperlipidemia population taking the community intervention program in districts of Beijing.The insulin resistance and insulin action index(IAI) were calculated with fasting blood glucose(FBG) and fasting blood insulin(FINS),and analyzed the relationship of variety on their blood glucose,serum lipids and body weight,body mass index(BMI),waist circumference,waist hip ratio(WHR).Results 1) Blood glucose(FBG),triglyceride(TG),waist circumference and WHR had significant positive relationship with IR but negative with IAI;2) In the intervention group,FBG and TG were reduced significantly in the subgroup with highest IAI.Conclusions IR was related with blood glucose,serum lipids,waist circumference and WHR,but no significant relation with body weight and BMI;It was possible that IR had some effect on dietary intervention.

Objective To study the symptom dimensions of Chinese patients with obsessive-compulsive disorder(OCD). Methods Symptom checklist in expert versions of Dimensional Yale-Brown Obsessive-Compul-sive Scale (DY-BOCS) was used to assess the symptom dimensions of 139 OCD patients. Results Nearly half of the patients had one dimension (50.4%). The frequency of patients with two or three dimensions was 24.5% and 14.4%. Patients with four to seven dimensions were very few and the frequency were 5.8% ,3.6% ,0.7% and 0.7% ,respectively. The most common symptom dimensions were symmetry (67.6%), contamination (43.2%) and aggressive (31.7%). The frequency of patients with miscellaneous, somatic, sex and religious, hoarding di-mension were 18.7%, 11.5% , 10.8% ,8.6% ,respectively. The frequency of male patients with symmetry dimen-sion was higher than that of the female patients(75.8%/52.1%, P<0.01), and the frequency of female patients with contamination dimension was higher than that of male patients (56.3%/36.3%, P<0.05). There were no differences in other dimensions between male and female patients. The early-onset patients had a greater of symp-toms in the symmetry dimension than late-onset patients and there were no differences between these two groups in other dimensions (77.6% vs 60.5%, P<0.05 ) . Conclusion Preliminary data suggest that the symptom di-mension approach may aid in the identification of subtype of OCD.

Objective To study the characteristics of life events, coping styles and social supports in anxiety disorders patients. Methods 50 patients with generalized anxiety disorders (GAD), 44 patients with obsessivecompulsive disorders (OCD),23 patients with social anxiety disorders (SAD) and 99 healthy people were assessed by life event scale(LES),simplified coping style questionnaire(SCSQ) and social support rating scale (SSRS). Results Compared with healthy people, patients with GAD, OCD and SAD were all had higher scores of total life events (GAD 22.46±18.44;OCD 23.68±28.31;SAD 17.22±14.97;Healthy People 6.64±9.71)( F =14.216,P =0.000) and negative life events(GAD 18.76±17.99;OCD 20.02±24.98;SAD 12.00±13.16;Healthy People 4.56±7.51)( F =14.391,P =0.000).All patients were apt to choose positive styles less( F =16.505,P =0.000) and got less social supports totally ( F =26.506,P =0.000). The objective social supports( F =7.494,P =0.000)and subjective social supports ( F =26.985,P =0.000) were less and the utilization of social supports was lower ( F =13.931,P =0.000) in patients.Conclusions 1. Anxiety disorders patients often experience more or more serious life events, especially negative life events, are more likely to choose negative coping styles, and get less social supports. 2. Anxiety disorders may be related with people's characteristics of life events, coping styles and social supports.

OBJECTIVETo observe clinical therapeutic effect of fuzhong (supporting the middle-jiao) manipulation of tuina for infantile anorexia.

METHODSEighty-one children with anorexia were treated with fuzhong manipulation, including abdominal kneading, acupressure at Zhongwan (CV 12), Lanmen (Extra), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6), spine pinching, warm moxibustion and warm scraping with supporting-yang cupping, three times a week, six times as a session. Onset time, therapeutic effect and TCM symptom scores before and after treatment were observed after two sessions and differences of therapeutic effect among different patterns were compared.

RESULTSSeventy-two children had the effect in one session while 41 children had the effect within half of a session. 38 cases were clinically cured, 15 cases were markedly effective, 23 cases were effective and 5 cases were failed. The total effective rate was 93.8%. Compared with before treatment, TCM symptom scores, including appetite, food intake, complexion and defecation, were all obviously improved after treatment (all P < 0.001). The clinical cured rate was 45.2% (19/42) in the pattern of dysfunction of spleen in transportation, 45.8% (11/24) in the pattern of qi deficiency of spleen and stomach, 50.0% (4/8) in the pattern of yin deficiency of spleen and stomach, 57.1% (4/7) in the pattern of liver sufficiency and spleen insufficiency, which had no obvious differences among different patterns (all P > 0.05).

CONCLUSIONThe fuzhong manipulation of tuina has quick onset time and satisfied clinical therapeutic effect, which could obviously improve symptoms and is fit for different patterns of infantile anorexia.
