OBJECTIVETo study the correlation between the Chinese medicine (CM) syndrome types of the Uighur and Han people and levels of blood lipids and fibrinogen in premature coronary heart disease (PCHD) patients.

METHODSRecruited were 196 Uighur and 189 Han patients with PCHD first confirmed by coronary angiography at the Heart Center of First Affiliated Hospital of Xinjiang Medical University and Traditional Chinese Medicine Hospital Affiliated to Xinjiang Medical University. Another 60 healthy volunteers were recruited as the healthy control group. CM syndromes were typed by physicians or those having higher professional titles at the cardiac internal medicine. The contents of triglyceride (TG) and total cholesterol (TC) were detected using oxidase method. The high-density lipoprotein cholesterol (HDL-C) level was detected using chemical modification enzymic method. The low-density lipoprotein cholesterol (LDL-C) level was detected using selective dissolution. The fibrinogen (FIB) level was detected using Clauss congeal principle.

RESULTSThe CM syndrome types of Uighurs were sequenced as filthy turbidity and phlegm obstruction syndrome (82 cases, 21.3%) > qi deficiency and blood stasis syndrome (61 cases, 15.84%) >cold accumulation in Xin meridian syndrome (39 cases, 10.13%) >Xin-Shen yin deficiency syndrome (14 cases, 3. 63%). The CM syndrome types of the Han nationality were sequenced as qi deficiency and blood stasis syndrome (69 cases, 17.92%) >filthy turbidity and phlegm obstruction syndrome (67 cases, 17.40%) > cold accumulation in Xin meridian syndrome (42 cases, 10.91%) > Xin-Shen yin deficiency syndrome (11 cases, 2.86%). There was no statistical difference in the syndrome type distribution between the two groups (P >0.05). Compared with the healthy control group, the levels of TG, LDL-C, and FIB increased, and the HDL-C level decreased in patients of filthy turbidity and phlegm obstruction syndrome and qi deficiency and blood stasis syndrome of the patient group. The HDL-C level decreased in the Uighur patients of Xin-Shen yin deficiency syndrome, showing statistical difference (P < 0.01, P < 0.05). Compared with the Han people of the same syndrome type, the TG level increased and the HDL-C level decreased in the Uighur patients of filthy turbidity and phlegm obstruction syndrome. The FIB level increased in the Uighur patients of qi deficiency and blood stasis syndrome with statistical difference (P<0.05). In the Uighur patients, filthy turbidity and phlegm obstruction syndrome was positively correlated with TG (r=0.469) and FIB (r=0.464), and negatively correlated with HDL-C (r=-0.382). Qi deficiency and blood stasis syndrome was positively correlated with FIB (r=0.72) with statistical difference (P<0.01, P<0.05). In the Han patients, filthy turbidity and phlegm obstruction syndrome was positively correlated with TG (r=0.445) and FIB (r=0.372), and negatively correlated with HDL-C (r=-0.37). Qi deficiency and blood stasis syndrome was positively correlated with TG (r=0.471) and FIB (r=0.459) with statistical difference (P<0.01, P<0.05).

CONCLUSIONCM syndrome types were correlated with TG, HDL-C, and FIB in PCHD Han and Uighur patients.

OBJECTIVEThe anemia of chronic disease (ACD) is usually defined as mild to moderate anemia occurring during the chronic infection, inflammation, neoplasm or trauma. It is the most common anemia among in-hospital adults. The insufficient endogenous erythropoietin (EPO) production is probably one of the pathogenic mechanisms of ACD. Inflammatory cytokines play an important role in the ACD pathogenesis. But nowadays there are few published papers on the childhood ACD in the world. This study aimed to detect the EPO levels in children's ACD, to explore the relationship between EPO and tumor necrosis factor alpha (TNF alpha) and interleukin-6 (IL-6) and, to evaluate the effect of recombinant human TNF alpha (rhTNF-alpha) on EPO gene expression.

METHODSSixty children were divided into ACD group (20 children), non-anemia (NA) group (19 children) and iron deficiency anemia (IDA) group (21 children) according to clinical diagnosis. Serum TNF alpha and IL-6 levels were detected with ELISA method. The EPO level was detected by chemical immulite method. The effect of rhTNF alpha on the expression of EPO gene was studied by culturing Hep G2 cell line and RT-PCR method.

RESULTSSerum EPO levels were different among the 3 groups (F = 44.68, P < 0.01). Serum EPO levels in ACD group were higher than those in NA group, while the hemoglobin levels were similar between the two groups. Serum EPO levels in ACD patients were lower than those in IDA patients. Serum TNF alpha levels were different among the 3 groups (F = 25.15, P < 0.01), and serum IL-6 levels were also different among the 3 groups (F = 13.16, P < 0.01). Serum TNF alpha and IL-6 levels in ACD group were higher than those in NA group. In ACD group, serum levels of both TNF alpha and IL-6 were not correlated to the serum level of EPO (r = -0.35, P > 0.05 and r = -0.05, P > 0.05, respectively). In vitro, rhTNF alpha inhibited the expression of EPO mRNA in hypoxia, and the inhibitory effects became stronger with the increase of rhTNF alpha (F = 64.20, P < 0.01).

CONCLUSIONEPO levels increased incompensatively in ACD children, which may be a cause of ACD. TNF alpha may cause anemia by inhibiting EPO production.

Objective To evaluate the diagnostic and therapeutic significance of serum free light chain (sFLC) in primary systemic(AL) amyloidosis. Methods Twenty-five patients with AL amyloidosis,including 18 men and 7 women with a mean age of 54(47-77) years old, were enrolled from October, 2005to May, 2010. sFLC was measured by immunoturbidimetric assay. The type of monoclonal light chain was judged upon sFLC κ/λ and its sensibility was compared with serum immunofixation and immunohistochemical analysis. Four patients were treated with M (T)D (melphalan/thalidomideand, dexamethasone), one with VD (velcade and dexamethasone) and four with high-dose melphalan followed by autologous stem cell support. The changes of sFLC were serially determined before and after treatment. Results Among the 25 patients with AL amyloidosis, two were κ light chains of precursor protein and 23 were λ light chains. Mean plasma cell in bone marrow was 3.5% (0-15%). Nineteen (76%) patients had abnormal elevated sFLC and abnormal κ/λ ratios, and 17(68% ) patients with immunofixation positive. The sFLC test had similar sensitivity as serum immunofixation (P = 0. 727 ). Twenty-one (84%) patients were shown to have either κor λ immunoreactive amyloid deposits on biopsied tissues. The sFLC test combined with serum immunofixation allowed the M protein to be detected in 22 (88%) patients. The positive rates of immunohistochemical analysis combined with sFLC test and/or serum immunofixation were 96%. Four patients with hematologic response showed obvious improvement in visceral organ involvement, but illness of 5 patients without hematologic response kept stable or progressed. Conclusions sFLC test is a sensitive qualitative and quantitative method to detect M protein. Preliminary data show the patients with obvious sFLC level decrease and/or κ/λ recovery to normal may have a high percentage of improved organs function. sFLC is critical index in diagnosing AL amyloidosis, which might help efficacy assessment.

Malignant tumors are one of the leading causes of death in the world. Considerable progresses have been made on the treatment of tumors in recent decades, especially in the prevention, early diagnosis and the model changing of therapeutics. But we are still facing tough challenges, including the increasing treatment burden and limited improvement of efficacy. In China, Chinese medicine (CM) provides a powerful arsenal to fight against tumors. CM can be well applied to the onset and progression of tumors in China, bearing the characteristics of multi-target, multi-phase and multi-effect. But there are also many problems demanding urgent attention in the use of CM. Some most debated problems in this field were summarized. We should upgrade our concepts in using CM, find its position scientifically, and establish evidence of its effect by high quality clinical research.

OBJECTIVETo observe effects of cold- and hot-property herbs and effects of hot and cold constitutions on the tumor growth of tumor bearing rats, and to observe the effect of Cinobufacini Injection (CI) on the tumor growth of tumor bearing rats of different constitutions.

METHODSEighty healthy male Wistar rats were randomly divided into eight groups, i.e., the tumor bearing control group, the tumor bearing heat syndrome group, the tumor bearing cold syndrome group, the heat syndrome tumor bearing group, the cold syndrome tumor bearing group, the tumor bearing CI group, the heat syndrome tumor bearing CI group, and the cold syndrome tumor bearing CI group, respectively. The weight and volume of rats' subcutaneous tumor were measured 14 days after tumor inoculation.

RESULTSThe weight and volume of tumor in the heat syndrome tumor bearing CI group [(3.55 +/- 1.12) g, (2864.44 +/- 1430.51) mm3] and the tumor bearing CI group [(4.29 +/- 1.14) g, (3397.19 +/- 1701.13) mm3] were significantly lower than those of the tumor bearing control group [(6.01 +/- 2.45) g, (6218.91 +/- 3837.64) mm3] and the cold syndrome tumor bearing CI group [(6.90 +/- 1.57) g, (6168.42 +/- 2457.03) mm3], showing statistical difference (P<0.05). There was insignificant difference among other groups.

CONCLUSIONSCI showed better tumor inhibition effects on tumor bearing rats of heat syndrome constitution, which indicated CI was of cold property. It might be possibly used in tumor bearing rats of heat syndrome constitution.

Objective To find a way to measure and count plane distribution of cells distributed on single layer and compare differences of undifferentiated mesenchymal cells of periosteum germinal layer from different parts of the body.Methods After counting the number of undifferentiated mesenchymal cells of periosteum germinal layer from different parts of the body microscopically and figuring out the number of cells per area unit in each periosteum specimen,the obtained data were statistically analyzed and the stratum structure of periosteum observed microscopically.Results The homogeneity of variance test showed homoscedasticity,with no statistical significance(P＞0.05).The analysis of variance found homoscedasticity but showed no statistical significance(F=0.253,P＞0.05).The periosteum of patel- la,tibial plateau and costa had two layers,while the periosteum of costal cartilage had three layers. Conclusions There is no conspicuous difference upon proliferation and evoluting activities of periosteum from different parts of body.Therefore,it is unnecessary to choose specific parts for drawing the periote- um in clinical situation.In the meantime,the structure of periosteum from different parts diversifies.

Disease recurrence is a main challenge in treatment of hepatocellular carcinoma (HCC). There is no generally accepted method for preventing recurrence of HCC after resection.

OBJECTIVEThe aim of this study was to evaluate the efficacy and toxicity of the CCCG-97 and BFM-90 protocols in the treatment of pediatric patients with B-cell non-Hodgkin's lymphoma (B-NHL) retrospectively, and to explore the optimal therapeutic strategy.

METHODSForty-five consecutive untreated patients (age of 18 years or less) with newly diagnosed B-NHL (including Burkitt Lymphoma and diffuse large B-cell lymphoma), treated in our hospital between July 1999 and December 2008 were enrolled in this study. The patients were classified into 2 groups by different protocols. From July 1999 to December 2004, twenty-one 3- to 13.8-year-old children were enrolled in the CCCG-97 group, with 1 in stage I/II, and 20 in stage III/IV(St Jude staging). From January 2005 to December 2008, twenty-four 2.8- to 14.1-year-old cases were enrolled in the BFM-90 group, with 3 in stage I/II, and 21 in stage III/IV (St Jude staging). The survival rates were evaluated by Kaplan-Meier analysis.

RESULTSForty of the 45 patients (88.9%) reached complete response (CR) after 2 courses of chemotherapy. In the CCCG-97 group, the CR rate was 95.2% (20/21 pts), while that in the BFM-90 group was 83.3% (20/24 pts). At a median follow-up time of 62 (17 to 131) months, the 5-year event-free survival (EFS) was 71.8% for all patients, and 69.1% for Stage III/IV, respectively. In the CCCG-97 group, the 3-year EFS was 76.2%. In the BFM-90 group, it was 75.0%. There was no significant difference in survival rates between the CCCG-97 and BFM-90 groups (P=0.975). Unfavorable events recorded were as follows: Death of progression before achieving CR during induction therapy in 4 cases, and relapse after achieving CR in 6 cases. The relapse rates were 19.0% (4/21 pts) in the CCCG-97 group and 8.3% (2/24 pts) in the BFM-90 group, with a non-significant statistical difference (P=0.292). Major toxicities were myelosuppression and mucositis, especially in the BFM-90 group, but were tolerable and manageable. five patients in the BFM-90 group received rituximab, 2 patients (Stage III) achieved CR, while the other 3 patients (Stage IV) had progressive disease or relapse.

CONCLUSIONSShort-pulse and intensive chemotherapy, stratified according to stage of disease, can improve the survival rate of pediatric mature B-NHL. The efficacy of the CCCG-97 protocol and BFM-90 protocol is comparable and the toxicity is tolerable.

OBJECTIVETo evaluate the pre-clinical effect of YJ-XCC1Z3 on the treatment of depression with the mice mouse.

METHODYJ-XCC1Z3 was administered at the dose of 405 mg x kg(-1) and 135 mg x kg(-1) to observe the locomotor activity with the mouse locomotor activity recorder apparatus, to observe the effect of YJ-XCC1Z3 on the duration of immohility in the mouse forced swimming test and tail suspension test, to observe the effect of YJ-XCC1Z3 on the body temperature and the metabolism of monoamine neurotransmitters in mouse brain in the mouse model of reserpine induced hypothermia, and to observe the effect of YJ-XCC1 Z3 on the times of 5-HTP induced head-twitches in mice.

RESULTThere were no significant changes in the locomotor activity, but a significant reduction in the immobility time was observed in the mice treated with YJ-XCC1Z3 405 mg x kg(-1) and imipramine in the forced swimming test and the tail suspension test. YJ-XCC1Z3 135 mg x kg(-1) and 405 mg x kg(-1) could improve the range of reserpine induced hypothermia in mice, and the latter could also enhance the times of 5-HTP induced head-twitches in mice. YJ-XCC1Z3 405 mg x kg(-1) and 135 mg x kg(-1) could increase the content of 5-HT and NE and decrease the ratio of 5-HIAA/5-HT in mouse brain, but the dose of 405 mg x kg(-1) could decrease the content of DA. The dose of 405 mg x kg(-1) could increase the content of 5-HIAA and had no obvious effect on the content of HVA and DOPAC.

CONCLUSIONYJ-XCC1Z3 shows potent antidepressant effect by improving the behaviour of the mouse in depression and not inducing hyperlocomotion in the mice. This effect results in the increase of the content of 5-HT and NE in the mouse brain. YJ-XCC1Z3 can decrease the metabolism of 5-HT to effect the content of 5-HT.

OBJECTIVECeramic brackets debonding by Nd:YAG laser is based on the thermal effect of laser, which may cause injury of the pulp tissue. In this study, the histological changes of pulp tissue that subjected to Nd: YAG laser irradiation with different power and time were observed.

METHODS20 New Zealand rabbits were included in this study. Ceramic brackets were bonded to the 4 incisors as routine. The ceramic brackets of left upper teeth that debonded mechanically were used as control group, while the brackets of right upper, left lower and right lower incisors were debonded by laser with 3 W 3 s (group A), 2 W 5 s (group B) and 5 W 2 s (group C) energies, respectively. The teeth were pulled out at 5 minutes, 1 day, 3 days, 1 week and 1 month after the debonding operations. Slides prepared from the pulp tissues of the debonded teeth were used to evaluate the injury of laser.

RESULTSIn comparison with the control group, pulp tissue of teeth that exposed to laser with different energy for 5 minutes showed mild capillary dilation. One day later, group A, B and C showed moderate capillary dilation, and group C also showed moderate infiltration. At 3 days, inflammation was disappeared in group B, whereas capillary dilation was found in group A. Hemorrhage and inflammation cells infiltration were found in group C. At 1 week, alleviation of capillary dilation was found in group A but not in group C. One month later, inflammation disappeared in group A, while pulp tissue in group C showed mild edema and capillary dilation.

CONCLUSIONNd:YAG laser of high energy may cause injury of the pulp tissue during debonding. Laser energy of 3 W 3 s could effectively debond ceramic brackets without irreversible pulp injury.
