Objective To investigate plasma glutathione S-transferase(GSTs) activity and GSTP1 gene Ile105Val polymorphism in Bijie City, Guizhou Province, a coal-burning fluorosis endemic area. Methods One hundred and sixty villagers from Yachi Twon using non-improved cooking stoves were selected as the non-intervened group in Bijie City, Guizhou Province where coal-burning fluorosis was prevailing; 153 villagers as the intervented group were chosen from Changchun Twon, where cooking stoves were improved; 151 villagers were served as the control group from Baiyunshan Twon, Changshun County without endemic fluorosis. The activity of GSTs was tested by colorimetric analysis with spectrophotometer. The genotype of the GSTP1 gene Ile105Val polymorphism, presenting as either homozygous wild-type (AA), or heterozygous mutation type (AG), or homozygous mutation type (GG), was detected through the PCR-RFLP procedure. Results The activity of GSTs in plasma of non-intervened group [(12.44±4.97) kU/L]was significantly lower than that of intervened group (P < 0.05), and that of intervened group[(20.78±6.20)kU/L]was significantly lower than that of control group[(24.30±6.27)kU/L, P< 0.05]. The difference of the enzyme activity of three groups were statistically significant (F = 51.71, P < 0.05), but this enzyme activity did not vary significantly in each sex of each grnup(P > 0.05). Compared intervened group [AA:67.3%(103/153), AG:29.4%(45/153),GG:3.3%(5/153)]and non-intervened group[AA:66.9%(107/160), AG:30%(48/160), GG:3.1%(5/160)]with control group[AA:74.8%(113/151), AG:25.2%(38/151), GG:0 (0/151)], the Ile105Val polymorphism site of GSTP1 gene had significant difference(χ2= 6.04,6.07, both P< 0.05), but not significant between intervened and non-intervened groups(χ2 = 0.02, P>0.05). Conclusions Fluorosis can decrease the activity of GSTs and introduce the GSTP1 gene Ile105Val polymorphism, intervention with the fluorine intake will improve the effect of fluoride on the body.

OBJECTIVE: To research the relation between the time-dependent appearances of myotibroblasts during the repair of contused skeletal muscle in rat and wound age determination. METHODS: A total of 35 SD male rats were divided into the control and six injured groups according to wound age as follows: 12 h, 1 d, 5 d, 7 d, 10 d and 14 d after injury. The appearances of myofibroblasts were detected by HE staining, immunohistochemistry and confocal laser scanning microscopy. Masson's trichrome staining was utilized to examine collagen accumulation in the contused areas. RESULTS: Immunohistochemical staining showed that α-SMA+ myofibroblasts were initially observed at 5 d post-injury. The average ratio of myofibroblasts was highest at 14 d post-injury, with all samples, ratios more than 50%. In the other five groups, the average of α-SMA positive ratios were less than 50%. The collagen stained areas in the contused zones, concomitant with myofibroblast appearance, were increasingly augmented along with advances of posttraumatic interval. CONCLUSION The immunohistochemical detection of myofibroblasts can be applied to wound age determination. The myofibroblasts might be involved in collagen deposition during the repair of contused skeletal muscle in rat.

OBJECTIVETo assess serum levels of endogenous endostatin in patients with clear cell renal cell carcinoma (CCRCC) and to determine the relationship of these levels to tumor stage, grade.

METHODSFrom March 2004 to October 2008, preoperative serum were obtained from 138 consecutive patients with CCRCC (73 patients in T1, 39 patients in T2, 20 patients in T3, and 6 patients in T4) and 40 healthy controls. Serum levels of endostatin were measured by sandwich-ELISA. Associations between circulating endostatin levels and clinicopathologic factors and clinical outcome were determined.

RESULTSEndostatin levels did not differ significantly between the patients with CCRCC (93.1 microg/L) and healthy controls (78.9 microg/L, P > 0.05). Serum levels of endostatin were significantly higher in the T2-4 CCRCC patients (107.2 microg/L) than those of the T1 patients (80.4 microg/L, P < 0.01). No significant difference was found in the endostatin levels among the T2-4 patients, or between healthy controls and the T1 patients. The serum endostatin concentration was significantly higher in the metastasis group (118.4 microg/L) than in the no metastasis group (89.5 microg/L, P < 0.05), but there was no significant difference between patients with distant metastasis group (122.0 microg/L) and lymph nodes metastasis (110.0 microg/L, P > 0.05). Patients with G3-4 tumors had significantly higher endostatin levels (111.8 microg/L) than those of patients with G1 (80.4 microg/L) and G2 tumors (86.2 microg/L, P < 0.01), but endostatin levels did not differ significantly between the two groups (P > 0.05).

CONCLUSIONPreoperative serum levels of endostatin elevated in patients with CCRCC and associated with higher stage and grade.

OBJECTIVETo investigate the effect of rhG-CSF on mobilizing bone marrow-MSCs, re-endothelialization and intima hyperplasia in carotid artery of rabbits post balloon catheter injury.

METHODSRabbits were treated with rhG-CSF (25 microg/kg, twice daily, i.p, n = 35) or saline (n = 32) for 5 days, then, carotid arteries of rabbits were injured by balloon catheter. The number of peripheral MSCs was detected with FACS. The morphology of injured artery was examined with hematoxylin and eosin stain, PCNA was determined with immunohistochemistry.

RESULTS(1) Number of peripheral MSCs was similar at baseline and significantly increased at 24 hours and peaked at 7 days and remained increased till 14 days post rhG-CSF. (2) Significant endothelial cell deletion was evidenced in the control group, while scatter endothelial cells was observed in the rhG-CSF group at 1 week post injury. Two weeks after injury, new endothelial area was significantly higher in rhG-CSF group compared to control group. At 4 weeks post injury, endothelial connection was evidenced and regularly displayed in rhG-CSF treated group. (3) PCNA-positive cells in the tunica intima were significantly lower in rhG-CSF treated rabbits at 7, 14 and 28 days compared that in control rabbits (all P < 0.01).

CONCLUSIONrhG-CSF could mobilize the bone marrow-MSCs and promote re-endothelialization and attenuate intima hyperplasia post balloon catheter injury in carotid arteries of rabbits.

Spontaneous pneumomediastinum(SPM) is an uncommon disease that is defined as the nontraumatic presence of free air in the mediastinum without any apparent underlying disease. We report a case of recurrent spontaneous pneumomediastinum without any direct precipitating cause. A 21-year-old woman was admitted to hospital suffering from chest pain that occurred during walking(?). She had previously been well. She did not complain of cough or vomiting prior to this presentation. Upon admission, the physical examination and Electrocardiogram findings were normal. The chest x-ray and chest computed-tomography showed a pneumomediastinum. She was successfully managed conservatively. Twenty seven months later, she was readmitted with chest pain, which again occurred during the same activity. The recurrent SPM was confirmed by the chest x-ray and chest computed-tomography. She was managed in the same manner as before and made an uneventful recovery. This is the first case of recurrent SPM in Korea.

OBJECTIVETo compare the differences between the direct immuno-fluorescent assay (DFA) and real-time quantitative PCR in detecting the Hantavirus (HV) in rat lungs.

METHODSFrom April to October in 2012, a total of 479 rats were caught by mouse-trap in residential or wild areas in Huxian, Jingyang, and Meixian of Shaanxi province, where haemorrhagic fever with renal syndrome (HFRS) was highly prevalent. The rats were dissected to take the two lungs, one was frozen and applied immuno-fluorescent assay to detect HV antigen while the other one was extracted its RNA and detected HV nucleic acid by real-time quantitative PCR. Then we compared the positive rate of the two methods.

RESULTSOut of the 479 rats, 105 were caught from residential areas and the other 374 were caught from wild areas. Among the 105 rats caught from residential areas, no HV were detected out neither by DFA nor by real-time quantitative PCR. Among the 374 wild rats, 13.1% (49/374) were detected HV positive by DFA and 14.7% (55/374) were detected HV positive by real-time quantitative PCR. The difference showed no statistical significance (χ(2) = 0.402, P = 0.526). When detecting each lung sample, the HV positive rate was 10.2% (49/479) under the detection by DFA while the HV positive rate was 11.5% (55/479) under the detection by real-time quantitative PCR. The difference had no statistical significance (χ(2) = 1.286, P = 0.257) and the consistency coefficient was 68.2% under the paired chi-square test analysis, which showed high consistency (u = 11.759, P < 0.05). The sensitivity of real-time quantitative PCR to detect HV was 77.6% (38/49) comparing with DFA as standard, and the specificity was 96.1% (413/430). Out of the 9 suspected HV positive sample detected by DFA, 6 were confirmed positive by real-time quantitative PCR and 3 were denied.

CONCLUSIONCompared with the DFA, real-time quantitative PCR could also be used to detect the infection of HV in rats, and the result might be more stable.
