Objective To determine the association of articular cartilage (AC) levels of YKL-40 with osteoarthritis (OA) at different stages of symptomatic severity in patients with knee OA.Methods 42 patients with knee OA were recruited into this study.The radiographic disease severity of OA was assessed by the Kellgren-Lawrence (K-L) grading system.11 patients with non knee OA were selected as normal control group.AC levels of YKL -40 were explored by immunohistochemical method.Symptomatic severity was determined using Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores from OA patients.Results YKL-40 levels in AC were positively related to WOMAC pain,function scores and total scores.WOMAC stiffness scores did not correlated with YKL-40 concentrations in AC.The correlation between AC YKL-40 levels and WOMAC scores was further analyzed by multinomial logistic regression.Multiple regression analysis showed that the correlation between AC YKL-40 levels and WOMAC scores was still significant after adjusting for other confounding factors.AC YKL-40 levels were significantly correlated with K-L grading in patients with knee OA.Conclusions YKL-40 in AC can be used as a potential biomarker for assessing the symptomatic severity of OA.

Objective To investigate the association between interleukin-10 (IL-10) gene promoter microsatellite polymorphisms and the susceptibility to hepatitis B virus infection in Han,Yi and Yao ethnicities in GuiZhou province.Methods 500 volunteers were selected from Guizhou province.Ailelic frequency of IL-10.G and IL-10.R loci was identified by short tandom repeat polymerase chain reaction.The relativity between allelic frequency and HBV infection was analyzed.Results Genotype data from H-W analysis on all the IL-10 polymorphisms indicated that it was a random distribution.Very high HBV infection rates were found in the native ethnic minorities of Guizhou province.The overall HBV infection rate among the total population was 67.00％,with the HBV infection rates of Yi nationality in Weining,Yi nationality in Qianxi,Yao nationality in Libo and Han nationality in Libo as 51.85％,42.86％,79.52％ and 84.30％,respe~vely.The polymorphisms distribution of IL- 10.G and IL- 10.R were statistically different among the ethnic groups (P＜ 0.05 ).The polymorphisms distribution of IL-10.R had no significant difference between HBV infection group and non-infection group,as well as among HBV natural removal group and non-infected group in all the ethnic groups.The frequency of IL-10.G 459 bp (19CA) was significantly higher in non-infection group than in the infected group (P＜ 0.05 ).The frequency of IL-10.G 471 bp (25CA) was significantly higher in the non-infection group than in the HBV natural removal group(P＜0.05).The polymorphisms distribution of IL-10.G did not show significant difference between the HBV infection group and the HBV natural removal group in all the ethnic groups.We did not find any differences in allelic and genotypic frequencies of IL-10.G between infection group and non-infection group in Yi nationality in Weining,and Yao nationality in Libo (P＞0.05),as well as HBV natural removal group and non-infected group (P＞0.05).Conclusion The polymorphisms distribution of IL-10.R and IL-10.G did not show significant difference in Yi,Yao and Han ethnics population living in Guizhou province.IL-10.G seemed to influence the susceptibility of HBV infection in Han,Yao and Yi ethnics population of Guizhou province.

OBJECTIVETo evaluate the efficacy and safety of using Jiangzhi Tongluo Soft Capsule (JTSC) combined with Atorvastatin Calcium Tablet (ACT) or ACT alone in treatment of combined hyperlipidemia.

METHODSA randomized, double blinded, parallel control, and multi-center clinical research design was adopted. Totally 138 combined hyperlipidemia patients were randomly assigned to the combined treatment group (A) and the atorvastatin treatment group (B) by random digit table, 69 in each group. All patients took ACT 20 mg per day. Patients in the A group took JTSC 100 mg each time, 3 times per day. Those in the B group took JTSC simulated agent, 100 mg each time, 3 times per day. The treatment period for all was 8 weeks. Serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were observed before treatment, at week 4 and 8 after treatment; and safety was assessed as well.

RESULTSAt week 4 and 8 after treatment serum TG decreased by 26.69% and 33.29% respectively in the A group (both P < 0.01), while it was decreased by 25.7% and 22.98% respectively in the B group (both P < 0.01). At week 8 decreased serum TG was obviously higher in the A group than in the B group (P < 0.05). Compared with before treatment, serum levels of LDL-C and TC levels decreased significantly in the two groups (all P < 0.01). There was no statistical difference in the drop-out value and the drop-out rate of serum LDL-C and TC levels (P > 0.05). At week 8 the serum HDL-C level showed an increasing tendency in the two groups. No obvious increase in peptase or creatase occurred in the two groups after treatment.

CONCLUSIONJTSC combined with ACT could lower the serum TG level of combined hyperlipidemia patients with safety.

OBJECTIVETo summarize lessons learned from an outbreak of severe acute respiratory syndrome (SARS) in China during the spring of 2004.

METHODSData of SARS cases were officially reported by Beijing Municipal Center for Disease Control and Prevention (BCDC) and Anhui Provincial Center for Disease Control and Prevention (APCDC) and results of epidemiological investigations were collected and analyzed.

RESULTSThree generations of 11 cases of SARS were identified during the outbreak. Initial two cases were most likely to be infected in Diarrhea Virus Laboratory of National Institute of Virology, China Centers for Disease Control and Prevention and main mode of transmission was direct contact with SARS patients. Delay in detecting initial case resulted in spread of the illness at hospitals and communities with two generations of secondary cases.

CONCLUSIONSSARS outbreak in 2004 has yielded following lessons for public health globally. (1) Lab bio-safety programs should be made and should be strictly abided by. Studies in highly pathogenic viruses such as SARS coronavirus should be utmost cautious. (2) Management systems of occupational exposure to virus and disease surveillance need to be strengthened to take all risk factors into account so as to detect potential patients with infectious disease as early as possible.

BACKGROUNDAn important characteristic of renal cell carcinomas and adrenal tumors is that these tumors may expand into the renal vein and inferior vena cava, and transform into tumor thrombi. This study was to evaluate the use of piggyback liver transplant techniques for surgical management of urological tumors with inferior vena cava tumor thrombus.

METHODSNineteen patients with renal cell carcinomas or adrenal tumors with inferior vena cava tumor thrombus were treated from November 1995 to April 2008. Their ages ranged from 29 years to 76 years (mean 54 years). The extent of tumor thrombus was infrahepatic (level I) in 2, retrohepatic (level II) in 7, suprahepatic (level III) in 6, and intra-atrial (level IV) in 4 patients. We used cardiopulmonary bypass with deep hypothermic circulatory arrest to remove the thrombi in 3 cases of level IV and in 2 cases of level III. In all level II, 4 level III, and 2 level IV cases, we used piggyback liver transplant techniques to mobilize the liver off of the inferior vena cava and to separate the inferior vena cava from the posterior abdominal wall.

RESULTSMean operative time was 5.1 hours, mean estimated blood loss was 2289 ml and mean blood transfusion was 12.84 U. One patient with adrenal cortical carcinoma and level IV thrombus died in the immediate postoperative period. Three patients were lost to follow up, and the other 15 survivors were followed from 5 months to 56 months. Eight of these 15 patients died due to metastasis; however 7 were still alive at the last follow-up.

CONCLUSIONSAn aggressive surgical approach is the only hope for curing patients diagnosed with urological tumors combined with inferior vena cava tumor thrombus. The use of piggyback liver transplant techniques to mobilize the liver off of the inferior vena cava provides excellent exposure of the inferior vena cava. Patients with a level II or level III inferior vena cava thrombus may be treated without using cardiopulmonary bypass.

OBJECTIVETo investigate the effect of Hirudin on random skin flap survival in rats.

METHODS24 SD rats were randomly divided into control group and experimental group. The "McFarlane flap (3 cm x 9 cm)" rat models were established on the rat dorsum. 3 ml Hirudin (30 ATU) was injected into the flap in the experimental group, while 3 ml saline in the control group. The injection was performed for 7 days. The flap survival area in the two groups was measured. The tissue samples were taken from proximal (I), middle (II) and distal (III) portions of flaps for histologic study. The VEGF and bFGF expression was also detected with immunohistochemistry method.

RESULTS7 days after operation, the flap survival rate was (69.52 +/- 3.23)% in the experimental group, while (50.36 +/- 2.37)% in control group, showing a significant difference between the two groups (P < 0. 01). In the middle portion, tissue edema and infiltration of neutrophils in experimental group was markedly slighter than that in control group. The VEGF and bFGF expression and neovascularization was enhanced markedly in experimental group.

CONCLUSIONSHirudin can increase the survival of random pattern skin flaps. It may increase the VEGF, bFGF expression through a series of complex regulatory pathway. Then flap neovascularization is promoted and the flap blood supply is increased.

OBJECTIVETo investigate the therapeutic effect of dorsal pentagonal flap for reconstruction of the web space in congenital syndactyly.

METHODSFrom October 2007 to August 2009, 10 patients with congenital syndactyly were treated with dorsal pentagonal flap for web space reconstruction. During the follow-up period, the patients underwent finger functional assessment and web space appearance examination. The satisfactory rate of patients was also investigated.

RESULTS10 patients with 17 reconstructed web spaces were followed up for 4-25 months (median, 15 months). Normal passive flexion and extension of fingers were achieved with good cosmetic result at web space. The abduction angle of fingers ranged from 30 degrees to 45 degrees. No web creep occurred and no secondary procedures were required. All the parents of the patients were satisfied with the results.

CONCLUSIONSWeb space reconstruction with dorsal pentagonal flap is easily performed with reliable blood supply and low re-operated rate. The cosmetic and functional result is satisfactory.
