Objective To study the relationship between self-esteem and childhood abuse, life events among male violent adolescent. Methods According to the modified overt aggression scale, juvenile delinquents were divided into violent group (n = 128 )and nonviolent group (n = 118 ). All the participants were investigated by Self-Esteem Scale (SES), Childhood Trauma Questionnaire-28 Item Short Form (CTQ-SF) and Adolescent SelfRating Life Events (ASLEC) and conducted correlation and regression analysis. Results ①Violent group had lower self-esteem scores ( 22.73 ± 3.30 ) than the nonviolent group ( 23.81 ± 3.30, P ＜ 0.05 ). Violent group had higher scores in physical abuse, sexual abuse, total life events, interpersonal relationship, punishment, and other (8.30 ±4.07, 7.23 ±2.26, 54.48 ±18.60, 10.09 ±3.84, 14.43 ±5.87, 4.93 ±3.15, 9.93 ±3.64), compared to the nonviolent group (7.27 ± 3.27, 6.60 ± 2.09, 45.40 ± 18.45, 8.42 ± 4.13, 11.07 ± 5.75, 3.66 ±2.81, 7.84 ±3.66, P＜0. 05). ②The self-esteem was significantly negative correlated with the childhood abuse and life events( r= -0. 143 ～ -0. 358, P＜ 0.01 ) among violent male adolescents. ③The physical abuse and punishment had significant prediction function of 15.6% on self-esteem. Conclusions Violent adolescents have low self-esteem, which is closely related to childhood abuse and adolescent life events.

OBJECTIVETo explore the relationship between Chinese medicine syndrome patterns (CMSP) and their associated factors in patients with type 2 diabetic nephropathy stage III (DN2-3).

METHODSRetrospective analysis was conducted on 209 patients with type 2 diabetes mellitus (T2DM). The patients were allocated into two groups, the DN2-3 group and the control group. Some related clinical materials and laboratory indexes, including age, course of disease, body mass index (BMI), glycosylated hemoglobin A1c (HbA1c), systolic blood pressure (SBP), diastolic blood pressure (DBP), blood levels of total cholesterol (TC), triglyceride (TG), high and low density lipoprotein (HDL and LDL), serum creatinine (Scr) and microalbuminuria (MALB) as well as their CMSP (both the essential syndrome and the superficial syndrome) in the DN2-3 group were collected and compared.

RESULTSSignificant differences were found between the DN2-3 group and the control group in aspects of course of disease (months, 107.74 +/- 96.19 vs. 82.03 +/- 79.10), BMI (kg/m2, 26.25 +/- 4.02 vs. 24.95 +/- 3.56) and Scr level (mmoL/L, 71.93 +/- 24.24 vs. 65.91 +/- 13.70, P < 0.05). The qi-yin deficiency SP (38 cases, 36.19%), and the blood stasis (51 cases, 48.58%) presented as the dominant essential and superficial CM-SP respectively in DN2-3 patients, holding the highest proportion. Analysis on the relationship of associated indices among patients with different CMSP showed statistical differences presented in level of MALB, i.e. which in pi-shen qi-deficiency SP (128.77 +/- 103.59 mg/24 h) was higher than in yin-deficiency dryness-fire SP and qi-yin deficiency SP (88.43 +/- 68.93 mg/24h and 82.60 +/- 55.22 mg/24 h, P < 0.05); it also presented in HbA1c (%) and TG levels(mmol/L), those in stasis SP were 10.73 +/- 2.71 and 2.29 +/- 1.58 ), in dampness SP were 8.80 +/- 2.19% and 4.37 +/- 5.92, and in stasis-phlegm SP were 8.83 +/- 2.09 and 2.40 +/- 2.18 (all P < 0.05).

CONCLUSIONSThe risk factors for occurrence of DN2-3 may be the course of disease, BMI and Scr. Qi-yin deficiency with blood-stasis is the most commonly encountered syndrome in patients with DN2-3. Relations of MALB with Pi-Shen qi-deficiency pattern; HbA1c with blood-stasis pattern, and TG with dampness syndrome are distinctly exhibited in them.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

The purpose of this research was to monitor quantitatively and study the dynamic changes and development rules of engraftment, chimera types, as well as relative amount of donor cells after allogeneic transplantation of mixed umbilical-cord blood from two units. An adult patient with acute myeloid leukemia received two units HLA one locus mismatched unrelated umbilical cord blood transplantation (2.5 x 10(7)/kg karyocytes in umbilical cord blood unit 1, and 1.53 x 10(7)/kg karyocytes in umbilical cord blood unit 2). Nine STR loci of the blood sample before and after transplantation were determined by quantitative detecting technique with fluorescence labeling polymerase chain reaction, while the engraftment and chimera types were qualitatively evaluated by comparing differential loci between the recipient and the donors. Then the relative proportion of chimera from two units of umbilical-cord blood in the patient after transplantation was calculated according to the differential gene peak areas of two donors on 377XL DNA sequencer after fluorescence scanning, and the engraftment level and the development rules of donor cells were analyzed. In addition, the results were also compared with that of HLA loci distinct analysis for engraftment. The results showed that two umbilical cord blood units at 15 days after transplantation were engrafted simultaneously and revealed a complete chimerism of the two. The relative amounts of chimera from unit 1 vs that of unit 2 were 51.3% vs 48.7%; subsequently relative amounts of chimera from unit 1 went up to 70.0% at 30 days, and that from unit 2 declined to 30.0%. However, at 52 days, only the genotype of umbilical cord blood unit 1 was detected, so that the engraftment turned to a complete chimerism of a single donor type. The one with fewer karyocytes was rejected and the one with more karyocytes finally engrafted in long-term. It is concluded that quantitatively detecting STR chimera with fluorescence labeling polymerase chain reaction can depict precisely the engraftment level and the change course of two umbilical cord blood units. It provides an accurate and reliable experimental basis for clinical umbilical cord blood application and donor selection, and is proved to be feasible for adult transplantation by using dual unit of umbilical-cord blood with HLA one locus mismatched at the same time.
