OBJECTIVETo explore clinical effects of internal fixation in treating displaced clavicle fracture combined with coracoid process.
METHODSFrom January 2005 to July 2012, 9 patients with displaced clavicle fracture combined with coracoid process were treated by internal fixation. Among them, there were 6 males and 3 females with an average age of 40.1 (ranged from 20 to 57) years old. According to Eyres classification: 3 cases were type II B, 1 case was type II A, 3 cases were type III B, and 2 cases were type V A. All patients had history of injury, and diagnosed as coracoid fracture X-ray and CT before operation. Herscovici criteria was used to evaluate function of shoulders joint after operation.
RESULTSSeven of 9 patients were followed up from 6 to 18 (averaged 11) months. The incisions were healed at stage I, coracoid process obtained bony healing, and reduction of acromioclavicular joint well. According to Herscovici criteria, 6 patients got excellent results and 1 in good.
CONCLUSIONInternal fixation for the treatment of displaced clavicle fracture combined with coracoid process could restore physiological anatomical position of coracoid process, and benefit for recovery of limb function.

The M and NP genes of H5N1 avian influenza virus (A/chicken/Hubei/489/2004) were amplified by RT-PCR from viral RNA,and cloned into pMD 18-T vector respectively.The expression plasmid containing the M gene (pHM6-m) or the NP gene (pHM6-np) was then constructed by inserting the M or NP gene into the pHM6 eukaryote expression vector; the constructed plasmid was then sequenced.32 BALB/c mice (6-week-old) were divided into four groups at random.Three groups of BALB/c mice were inoculated one time the intramuscular route with either 30 μg of plasmid pHM6-m,30 μg of plasmid pHM6-np or the mixture of plasmid pHM6-m (15 μg ) and pHM6-np(15 μg) respectively.A additional group of mice were injected with 100 μ1 PBS as controls.Two weeks later,all mice were challenged with homologous H5N1 avian influenza virus,and observed in the following 12 days.The survival rates of mice in the pHM6-m group,the pHM6-np group and mixed plasmids group were 62.5% ,25.0% and 50.0%,respectively.Results showed that effective protection could be provided by either pHM6-m or pHM6-np,but pHM6-m provided a better protective effect than pHM6-np.
7.Effects of SCF, LIF and bFGF on mouse spermatogonial stem cells proliferation in vitro.
Chinese Journal of Biotechnology 2002;18(6):754-757
The present study identified the favorable environment conditions for Spermatogomial stem cells in vitro according to their unique biological properties. Three growth factors, stem cell factor (SCF), leukemia inhibitory factor (LIF) and basic fibroblast growth factor (bFGF) were all found to independently contribute to the proliferation of mouse spermatogonial stem cell. The percentage of cell proliferation significantly enhanced by SCF at 30 ng/mL but decreased with heightening its combination after cultured 120 hours. The mice spermatogonial stem cells were significantly proliferated after 120 hours' culture with 10 ng/mL and 20 ng/mL (P < 0.01) of LIF, between 20 ng/mL and 50 ng/mL (P < 0.01) for bFGF. SCF and bFGF were significantly enhanced mice spermatogonial stem cells proliferation after these three factors combination. For LIF, no obvious effect was observed.

OBJECTIVETo study the effect of medicines for activating blood and reinforcing Qi on the number of new micro-vessels and the protein expressions of VEGF and bFGF in the infarcted myocardium edge area of acute myocardial infarction (AMI) model in rats.
METHODThe AMI model of rats was established. After the successful model establishment, rats were randomly divided into the sham-operated group, the model group, the Danshen-Huangqi (1 : 2) group, the Danshen-Huangqi (1 : 1) group, the Chuanxiong-Huangqi (1 : 2) group, the Danshen group, the Chuanxiong group, the Chishao group and the Shexiang Baoxin pill group, with five rats in each group. Rats in each medicated group were orally administered with drugs as per 13.5 g x kg(-1) x d(-1) once everyday for three weeks. The immunohistochemical SP method was adopted to detect the expression of vWF in myocardial tissues, and count the number of micro-vessels (MVC). The protein expression of VEGF and bFGF in myocardial tissues were determined by Western blot.
RESULTThe new micro-vessels stained by vWF factor could be found in the infarcted myocardium edge area of the sham-operated group, the model group and all of medicated groups. The sham-operated group show unobvious new micro-vessels in myocardial tissues. A small amount of new micro-vessels could be seen in the infarcted myocardium edge area of the model group. Whereas a larger number of micro-vessels could be seen in the infarcted myocardium edge area of all of medicated groups. The differences between the sham-operated group and the model group had statistical significance (P < 0.05). The differences between each medicated group and the model group had statistical significance as well (P < 0.05 or P < 0.01). The lowest protein expression of VEGF and bFGF was found in myocardium of the sham-operated group, with the statistical significance compared with the model group (P < 0.05). Compared with the model group, each medicated group showed significant increase in the protein expression of VEGF and bFGF, with the statistical significance between them (P < 0.05 or P < 0.01).
CONCLUSIONThe Danshen group, the Chuanxiong group, the Chishao group, the Danshen-Huangqi (1 : 2) group, the Danshen-Huangqi (1 : 1) group and the Chuanxiong-Huangqi (1 : 2) group show the effect in promoting angiogenesis. Their mechanism for promoting angiogenesis may be related to the improvement of the protein expressions of VEGF and bFGF, so as to increase the contents of VEGF and bFGF and promote the angiogenesis of new vessels.

Objective To investigate the distribution of high-arsenic drinking water in Honghu city of Hubei province in order to provide a scientific basis for prevention and control of endemic arsenic disease.Methods Investigations were made in 22 townships(towns,districts),68 natural villages of the drainage areas of the Dongjing River,the Neijing River and the Yangtse River in 2006 and 2007,with the townships(towns,districts)around Shahu town in Xiantao city as the focal point.1000 water samples were drawn each year,which was 10% of all the wells in every natural village.Using sampling investigation,water arsenic Was determined by half-quantitative fast reagent kit.All samples of water with arsenic exceeding the standard(≥0.03 mg/L)were re-determined according to state standard.Surveys on the disease was carried out in the villages(brigades)where arsenic exceeded the standard.Results A total of 2000 samples were surveyed from 68 natural villages,of which there were 401 samples from 48 villages exceeding the standard in a rate of 20.05%(401/2000).The highest arsenic content Was 0.71 mg/L.The high arsenic water sources were distributed mainy in the drainage areas of the Dongjing River and the Neijing River,but no patients with endemic arsenic disease were found.Conclusions The high arsenic water sources are distributed mainly in the drainage areas of the Dongjing River and the Neijing River.It is suggested that the interrelated government departments should take precise measures to impmve the quality of drinking water and ensure safe water to the residents in high arsenic areas.
