BACKGROUNDMycobacterium abscessus (M. abscessus) can cause a variety of human infections, involving the lung, skin and soft tissues, and is generally believed to be acquired from environmental sources. The aim of this study was to investigate the molecular diversity and antibiotic susceptibility of M. abscessus isolates as the basis for strategies to improve control and management of infection.
METHODSSeventy M. abscessus isolates from patients attending the Guangzhou Thoracic Hospital were identified from 2003 to 2005 by biochemical tests, gas chromatography, polymerase chain reaction (PCR)-restriction analysis (PRA) of heat shock protein gene hsp65, and sequencing of the quinolone resistance determining regions (QRDRs) of gyrA. Susceptibilities to six antibiotics were determined by micro-broth dilution. Isolates were genotyped using randomly amplified polymorphic DNA (RAPD) analysis.
RESULTSMost isolates (63/70; 90%) were susceptible to amikacin but rates of susceptibility to other antibiotics varied from moderate, clarithromycin (60%) and imipenem (43%), to low for ciprofloxacin and ofloxacin (3%), and 87% of isolates had intermediate susceptibility to cefoxitin. RAPD analysis showed that the 70 clinical isolates displayed 69 unique RAPD patterns.
CONCLUSIONSThe high genetic diversity of isolates suggests that they are not transmitted from person to person but, presumably, are acquired independently from environmental sources. M. abscessus isolates displayed variable levels of susceptibility to all antibiotics tested, other than amikacin, indicating a need for routine susceptibility testing to guide treatment.

Objective To investigate the clinical feature,treatment,and prognosis of hospitalized patients with jaw osteoradionecrosis. Methods A total of 93 cases with jaw osteoradionecrosis treated between 2000 and 2010 was reviewed.Of the 93 cases,79 cases were with mandible lesions,13 cases with maxillary lesions,and 1 case with both mandible and maxillary lesions.Sixty-six cases received one course of radiotherapy,with the radiation doses of 34 -90 Gy (mean 64.6 Gy).Twenty-two cases experienced tooth extraction or other operative procedures before exhibition of the clinical symptoms for osteoradionecrosis.The interval time between radiotherapy and the onset of osteoradioneerosis varied from 2 weeks to 32 years (mean 54 months).Results Of 93 cases,56 patients underwent radical resection of the pathologic bone and reconstruction with free tissue flaps,in whom 7 cases received the second surgery due to microvascular thrombosis in flap vessels,and flaps were survival by new vascular anastomosis in 3 cases,the failed flaps were removed and replaced successfully by non vascularized bone grafts in 2 cases,and the failed flaps removed and the defects were repaired with adjacent skin in other 2 cases.In the 56 cases,only one case was with disease recurrence and 53 cases with significant improvement in chewing and swallowing functions.Only 2 of 93 cases underwent resection of the pathologic bone and reconstruction with titanium plates,and thereafter they encountered titanium exposure.Scaling of osteoradionecrosis lesions was applied to 20 of 93 patients and 9 cases of them were with disease recurrence.Fifteen cases had resection of the effected mandible without reconstruction.Disease relapse was encountered in 2 of them,others had poor chewing and swallowing.Conclusions The mandible is more susceptible to osteoradionecrosis than maxilla.Radical resection with reconstruction by free tissue flap is recommended for the treatment of jaw osteoradionecrosis,and scaling and reconstruction only with titanium plate should be avoided because of high risks of titanium exposure and disease relapse.

OBJECTIVETo investigate the expression of prostate stem cell antigen (PSCA) in human pancreatic carcinoma and explore its role in the oncogenesis of pancreatic cancer.
METHODSA pancreatic carcinoma tissue microarray was constructed, which contained 10 normal adult pancreas tissues, 12 chronic pancreatitis tissues and 78 pancreatic carcinomas. Immunohistochemistry was employed to detect the expression of PSCA, and the relation between PSCA expression and the clinicopathological factors of pancreatic carcinoma was analyzed.
RESULTSThe positivity rate of PSCA in pancreatic carcinoma was 79.5% (62/78), and PSCA staining was more intense in the malignant cells than in the benign cells (chi2=15.81, P<0.005) and chronic pancreatitis tissues (chi2=11.33, P<0.005). No obvious association was found between PSCA expression and the other variables of pancreatic carcinoma (including gender, age at surgery, tumor grade, and TNM stages).
CONCLUSIONThe expression of PSCA can be related to the development of pancreatic cancer, but not to the clinicopathological factors of the tumor.

OBJECTIVETo further study the characteristics of drugs with neutral property in two-way application and conditioned dominance by observing the action characteristic of 10 traditional Chinese medicines with neutral property in hemorheological indicators of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats.
METHODThe model of heat stagnation and blood stasis syndrome rats was established by injecting carrageenan and dry yeast, while the model of cold stagnation and blood stasis syndrome rats was established by body freezing. Subsequently, 10 traditional Chinese medicines with neutral property, 5 traditional Chinese medicines with heat property and 5 traditional Chinese medicines with cold property were selected for intervention to observe the changes in such indicators as whole blood viscosity, plasma viscosity and hematocrit and analyze the action characteristics of drugs with neutral property.
RESULTANOVA showed that among six of the 10 traditional Chinese medicines with neutral property, including Typhae Pollen, Sarcandrae Herba and Sappan lignum, could obviously increase the hemorheological indicators of both heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats; five traditional Chinese medicines with cold property, such as Salviae Miltiorrhizae Radix et Rhizoma, Leonuri Herba, Rhei Radix et Rhizoma, could significantly ameliorate the hemorheological indicators of heat stagnation and blood stasis syndrome rats (P < 0.01 or P < 0.05), and Salvia Miltiorrhiza Radix et Rhizoma alone could ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.05); all of the five traditional Chinese medicines with heat property could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.01), among which Carthami Flos and Notoginseng Radix et Rhizoma could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats. According to the average high-shear blood viscosity analysis, drugs with neutral property showed similar action characteristics to those with cold property in ameliorating hemorheology indicators of heat stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity; and traditional Chinese medicines with neutral property have the similar action characteristics to those with heat property in improving the hemorheology indicators of cold stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity.
CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with cold property; but under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with heat property. This indicates that traditional Chinese medicines with neutral property show both heat and cold properties under he conditions of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome.

OBJECTIVETo investigate the expressions of prostate stem cell antigen (PSCA) and Claudin-4 in human pancreatic carcinoma and to discuss its role in the ontogenesis of pancreatic cancer.
METHODSPancreatic carcinoma tissue microarray was constructed, containing 100 cores of 10 normal adult pancreas tissues, 12 chronic pancreatitis tissues, and 78 pancreatic carcinomas. The expressions of PSCA and Claudin-4 were detected using immunohistochemical method and the relationship between PSCA and Claudin-4 and the pancreatic carcinoma was analyzed.
RESULTSThe positive expression rates of PSCA and Claudin-4 protein in pancreatic carcinoma were 79. % and 88. % respectively. PSCA and Claudin-4 staining were more intense in malignant cells than in chronic pancreatic tissues and normal adult pancreas tissues. No evidence was found for an association between expressions of PSCA and Claudin-4 and other variables, including gender, age at surgery, and tumor grade.
CONCLUSIONSThe expressions of PSCA and Claudin-4 are related to the pancreatic carcinomas. PSCA and Claudin-4 play a role in the development of pancreatic cancer, but PSCA and Claudin-4 are not correlated with the clinical pathology of tumor.

OBJECTIVETo study the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property by observing the action characteristic of 10 traditional Chinese medicines capable of promoting blood circulation and removing blood stasis with neutral property in the microcirculation in rats with heat stagnation and blood stasis syndrome.
METHODThe rat model with heat stagnation and blood stasis syndrome was established by injecting carrageenan and dry yeast, and the rat model with cold stagnation and blood stasis syndrome was built by the body freezing method. Ten traditional Chinese medicines with neutral property, including 5 with hot property and 5 with cold property, were selected for intervention to observe blood flow rate and flow state indicators in rat auricles and make a comparative analysis on action characteristics of traditional Chinese medicines with neutral property.
RESULTANOVA showed that among the 10 traditional Chinese medicines with neutral property, 6 such as Typhae Pollen, Sappan Lignum and Vaccariae Semen can obviously increase the blood flow rate (P < 0.01 or P < 0.05) in the above two models; all of the 5 traditional Chinese medicines with cold property can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat model with heat stagnation and blood stasis syndrome, but only Salvia miltiorrhiza can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat models with cold stagnation and blood stasis syndrome, while other medicines showed no notable effect; among the 5 traditional Chinese medicines with hot property, Carthamus tinctorius and Ligusticum chuanxiong can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat models with cold stagnation and blood stasis syndrome, but had no obvious effect to the blood flow rate in the rat models with heat stagnation and blood stasis syndrome. According to the analysis on average blood flow rate, traditional Chinese medicines with natural and cold properties showed similar effect on heat stagnation and blood stasis syndrome and better effect in increasing blood flow rate than those with hot property; those with natural and hot properties showed similar effect and better effect in increasing blood flow rate than those with cold property.
CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with those with cold property; wile under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with the Chinese medicinal herbs with hot property. This indicates the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property to some extent.
