BACKGROUND:Previous studies have suggested that the risks for coronary atherosclerotic plaque progression and in-stent restenosis are increased in patients with coronary heart disease combined with type 2 diabetes. OBJECTIVE:To explore the predictive factors for in-stent late loss and non-culprit coronary lesion progression in patients with type 2 diabetes mel itus. METHODS:A total of 399 stenting patients were enrol ed, including 179 diabetic patients and 220 non-diabetic patients. The clinical materials, angiography parameters and biochemical markers were col ected. The difference between the two groups was compared, and also we conducted subgroup analysis in the diabetic patients. Low-density lipoprotein cholesterol, hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein were detected at days 3, 120, 210 and 360 after stenting. RESULTS AND CONCLUSION:Compared with non-diabetic patients, the stent length (P=0.18) was longer and the stent diameter (P=0.002) was smal er in the diabetic patients. The minimal lumen diameters of post-procedure and fol ow-up angiography in the diabetic group were significantly decreased (P=0.001, P=0), and the diabetic patients also showed severe coronary artery stenosis instantly and within the fol ow-up after stenting (P=0.038, P=0.004). The fol ow-up angiography showed that the diabetic patients had more late loss and restenosis (P=0, P=0.097). Furthermore, in the subgroup analysis of diabetic patients, the levels of hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein were significantly increased in the patients with restenosis and non-culprit lesion progression. These findings indicate that diabetic patients appear to have the higher incidence of restenosis and non-culprit lesion progression. Moreover, hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein are effective predictors for in-stent late loss and non-culprit coronary lesion progression.

OBJECTIVETo investigate the blood supply patterns of the anteriorlateral thigh adipofascial flap for clinical applications.

METHODSTo investigate the blood supply patterns of the anteriorlateral thigh (ALT) adipofascial flap, 16 fresh cadavers were anatomically examined by intraarterial injection of colored latex. Three-dimensional analysis of the vasculature of the subcutaneous adipofascial tissue was performed. Sixteen patients underwent microsurgical correction with the ALT adipofascial flap. Among them, there were fifteen with hemifacial atrophy, one with micromastia.

RESULTSThe three-dimensional arterial structures of the ALT adipofascial flap were the same in all the cadaver specimens. Each layer of the adipofascial tissue was supplied by several blood vessels of the axial pattern, especially in the deep layer. Sixteen patients were successfully treated with this flap. The postoperative follow-up ranged from six months to eleven years. There was not postoperative flap necrosis or absorption of the fatty tissue. Stable restoration of the facial contour or the breast was achieved. The donor-site morbidity was minimal.

CONCLUSIONThe blood supply of the ALT adipofascial flap is reliable. A considerable amount of the fatty layer of the flap can be removed primarily. It is a preferable procedure for reconstructing soft tissue defects.

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52

Objective To investigate the expression and correlation of NKG2D and sMICA in lung cancer patients. Methods By collecting 30 lung cancer patients as the test group,and taking 30 healthy volunteers as the contrast group, the expression of NKG2D and sMICA in the two groups were examined separately by FACS and ELISA method. Results The expressions of NKG2D in the two groups were (81.56±8.78) %, (85.63±6.62) %. The lung cancer patients were high remarkable. There was a significant difference between the two groups (P <0.05). The expression of sMICA in the two groups were (354.13 ±80.575) pg/ml,(216.53±48.175) pg/ml. The lung cancer patients were low remarkable. There was a significant difference between the two groups (P <0.01). There was a significant relation between the two groups (r =-0.349, P =0.006). Conclusion The expression of NKG2D and sMICA may provid one of the immune targets for diagnosing that can forecast the immune state and malignant metastasis of the lung cancer patients. The significant relation between NKG2D and sMICA may take on main role in the immune escaping of tumor. It may provide the suitable target of the patients for tumor organisms and immune treatment.

OBJECTIVETo study the molecular epidemiological characteristics of hantavirus seen during 2000-2003 in Qingdao region of Shandong province.

METHODSSera were collected from 64 patients with hemorrhagic fever with renal syndrome (HFRS) and viral RNA was extracted from the sera. HTN and SEO universal primers were designed as outer primers and HTN and SEO specific primers as inner primers. G1 gene region of M segment from hantavirus was amplified by using RT-nest-PCR for sequencing. The data of nucleotide sequences were analyzed by DNA star software.

RESULTSSix cases were positive by HTN specific primer of total cases (9%); 25 of 64 cases by SEO specific primer (39%); total positive rate was 48%. In general, SEO type was a prevalent type of hantavirus in Qingdao region. The variation of the nucleotide sequences among SEO viruses (nucleotide sequence divergence ranged from 0.3% approximately 8.9%) was lower than that among HTN type (nucleotide sequence divergence ranged from 2.6% approximately 11.2% ).

CONCLUSIONMajority of hantavirus found in Qingdao region belonged to SEO type and still a few strains belonged to HTN type. Most of the HTN viruses were detected in Jiaonan county.

OBJECTIVETo observe the effect of yishen capsule (YSC) on preventing the recurrence of chronic glomerulonephritis (CGN) and to explore its mechanism preliminarily.

METHODSCGN patients were assigned to the treated group (61 cases) and the control group (48 cases) and all of them were orally administered with 4 mg of Perindopril twice a day, but 3 capsules of YSC, thrice a day, were given additionally to patients in the treated group. The therapeutic course for both groups was 18 months. The recurrence rate of CGN at the 6th, 12th, and 18th month in the two groups was observed and compared, and the changes of 24-h urinary protein quantity and T-lymphocyte subsets before and after treatment were observed as well.

RESULTS(1) Comparison of recurrence rate between the two groups showed insignificant difference at the 6th month, but it did show significant difference at the 12th and the 18th month, which was significantly decreased in the treated group than in the control group (P<0.05, P<0.01); (2) The 24-h urinary protein quantity at the 18th month decreased significantly in both groups (P<0.05, P<0.01), but in the treated group was more significant (P<0.01); (3) T-lymphocyte subsets showed no obvious change in the control group after treatment (P>0.05), while in the treated group, it showed significant increase in CD3, CD4 and CD4/CD8 (P<0.05 or P<0.01) and significant decrease in CD8 (P<0.05), and also the difference after treatment in T-lymphocyte subsets between the two groups was significant (P<0.05 or P<0.01).

CONCLUSIONYSC has marked effects in reducing the recurrence of CGN and in decreasing urinary protein, and its mechanism might be related with its function in regulating the ratio of T-lymphocyte subsets to enhance the immunity of patients.

OBJECTIVETo evaluate the clinical effects of Chinese medicine (CM) on acute myocardial infarction (AMI) with a prospective cohort study.

METHODSA total of 334 AMI patients from January 2007 to March 2009 were consecutively enrolled, and were assigned to a treatment group (169 cases) treated with combined therapy (CM for at least one month and Western medicine) and a control group (165 cases) with Western medicine alone. Clinical data including age, gender, smoking, medical history, infarction area, heart functional classification, CM syndrome scores, blood-stasis syndrome score, primary end-point (death, nonfatal myocardial infarction, and revascularization) and secondary end-point (ischemic stroke, rehospitalization due to angina, heart failure and shock), were collected. CM syndrome scores, blood-stasis syndrome score, primary end-point and secondary end-point were collected during the 6-month follow-up. Kaplan-Meier method was used for the survival analysis. The multifactor analysis was analyzed by Cox proportional hazards regression.

RESULTSAt the end of 6-month the CM syndrome score and bloodstasis syndrome score in the treatment group were lower than those in the control group (P<0.01), especially the symptoms of chest pain, spontaneous perspiration and insomnia. Rehospitalization rate due to angina during the 6-month follow-up in the treatment group (2.96%) was lower than that in the control group (7.88%, P<0.05). Kaplan- Meier survival curve showed that event-free cumulated survival of rehospitalization due to angina during the 6-month follow-up in the treatment group was higher than that in the control group (Log rank 4.700, P=0.03). Cox regression analysis showed that heart dysfunction [hazard ratio (HR)=1.601, 95% CI=1.084-2.364, P=0.018] and diabetes mellitus (HR=1.755, 95% CI=1.031-2.989, P=0.038) were hazard factors to end-point, whereas CM (HR 0.405, 95% CI=0.231-0.712, P=0.002), percutaneous coronary intervention (PCI, HR=0.352, 95% CI=0.204-0.607, P<0.001) and angiotensin converting enzyme (ACE) inhibitors (HR=0.541, 95% CI=0.313-0.936, P=0.028) were protective factors.

CONCLUSIONSCM therapy could decrease CM syndrome scores and blood-stasis syndrome score, reduce the rehospitalization rate during 6-month follow-up due to angina. Heart dysfunction and diabetes mellitus were hazard factors to end-point, whereas CM, PCI and ACE inhibitors were protective factors.

OBJECTIVETo explore the incidence of dementia among elderly people in Xi'an and its related risk factors.

METHODSSubjects that had been studied on the prevalence of dementia were follow-up, and the incidence of dementia, Alzheimer disease (AD) , and vascular dementia (VD) were counted by person-years. The clinical diagnosis on dementia,AD and VD were based upon the 3rd Edition of Diagnostic and Statistical of Manual of Mental Disorder, Revised version (DSM-III-R) and NINCDS-ADRDA criteria.

RESULTS2197 subjects of non-dementia being identified in 1998, were re-surveyed in 2001. Out of them, 47 new cases of dementia including 37 cases of AD and 8 cases of VD were identified, with an annual incidence rates of dementia, AD and VD as 0.68%, 0.54% and 0.12% among those of 55 years and over and 0.89%, 0.69% and 0.17% in 65 years and over, respectively. Analysis from single factor logistic regression showed that age and education but not gender were closely related to the occurrence of AD. On the contrary, age, hypertension and stroke were closely related to the occurrence of VD.

CONCLUSIONThe incidence of dementia in the "Xi' an cohort" was similar to that being reported from other countries. AD and VD were an age-related diseases but education seemed to have had great protective effect while lack of formal education served as risk factor to AD.

OBJECTIVE To investigate the effects of LW-AFC, a new formula derived from Liuwei Dihuang decoction, on gut microbiota and the behavior of learning and memory of SAMP8 mice, a mouse model of Alzheimer Disease (AD), and identify the specific intestinal microbiota correlating with cognitive ability. METHODS Morris-water maze test, novel object recognition test and shuttle-box test were conducted to observe the ability of learning and memory. 16S rRNA amplicon sequencing (Illumina, San Diego, CA, USA) was employed to investigate gut microbiota. RESULTS The treatment of LW- AFC improved cognitive impairments of SAMP8 mice, including spatial learning and memory ability, active avoidance response, and object recognition memory capability. Our data indicated that there were significantly 8 increased and 12 decreased operational taxonomic units (OTUs) in the gut microbiota of SAMP8 mice compared with senescence accelerated mouse resistant 1 (SAMR1) strains, the control of SAMP8 mice. The treatment of LW- AFC altered 22 (16 increased and 6 decreased) OTUs in SAMP8 mice and among them, 15 OTUs could be reversed by LW-AFC treatment resulting in a microbial composition similar to that of SAMR1 mice. We further showed that there were 7 (3 negative and 4 positive correlation) OTUs significantly correlated with all the three types of cognitive abilities, at the order level, including Bacteroidales, Clostridiales, Desulfovibrionales, CW040, and two unclassified orders. LW-AFC had influences on bacterial taxa correlated with the abilities of learning and memory in SAMP8 mice and restored them to SAMR1 mice. CONCLUSION The effects of LW-AFC on improving cognitive impairments of SAMP8 mice might be via modulating intestinal microbiome and LW-AFC could be used as a potential anti-AD agent.
