Objective To summarize the clincal effect of open reduction and internal fixation with locking-proximal-humerus-plate(LPHP)to treat proximal humeral fractures.Methods A total of 19 eases with proximal humeral fractures were treated with LPHP from August 2003 to February 2006 in this study.Their mean age was 58.6 years old.According to Neer classification,two cases were with two- part fractures,nine with three-part fractures and eight with four-part fractures including seven cases with osteoporosis.Redaction and fixation was done via deltopeetoral-groove approach.Bone graft was applied for five eases.Results The follow-up period was 3 to 32 months(mean 17 months).All cases were healed and the union period of 3-5 months.According to the Near shoulder score,the results showed that ten cases were excellent,6 cases good,with excellent rate of 84%.Conclusion The LPHP method is suitable for osteoporosis and comminuted proximal humeral fractures and enhances the treatment effect.

Ergosta-4,6,8(14),22-tetraen-3-one (ergone) is one of main components in many medicinal fungi. Ergone has been reported to possess the activities of diuresis, cytotoxicity, antitumor, immunosuppression, as well as treatment of chronic kidney disease. According to reported literatures, an overview of spectroscopy characteristics, content determination, pharmacological activity and pharmacokinetics, etc. for ergone is presented in this review. Furthermore, the present review can provide a certain reference value for the further study and development of ergone.

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus Tanbo-plucking the trigger points for scapulohumeral periarthritis (SP). Methods:A total of 80 patients with SP were randomized into an observation group and an EA group by the random number table, with 40 cases in each group. The EA group was treated with EA therapy, and the observation group was treated with EA therapy plus Tanbo-plucking the trigger points. After treatment, the visual analog scale (VAS) and Melle scores of the two groups were compared to evaluate the improvement of shoulder pain and functional activity, and meanwhile the clinical efficacy was observed. Results: After treatment, the total effective rate of the observation group was 95.0％ and the cure and markedly effective rate was 72.5％. The total effective rate of the EA group was 87.5％ and the cure and markedly effective rate was 42.5％. There was no significant difference in the total effective rate between the two groups (P>0.05). The cure and markedly effective rate of the observation group was higher than that of the EA group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the intra-group differences in VAS and Melle scores of both groups were statistically significant (bothP<0.001). The inter-group differences in the changes of the VAS and Melle scores after treatment were statistically significant (bothP<0.001). Conclusion: EA plus Tanbo-plucking the trigger points has a better curative effect than EA therapy alone in the treatment of SP.

To understand Lophatherum gracile plant community's structural characteristics, a survey of community structure and species diversity was conducted through quadrat sampling in Yongchuan district of Chongqing. The results showed that there were 386 species vascular plants, belonging to 117 families and 229 genera. Based on habitat, community structure and species composition, L. gracile were found in three community types: Pinus massoniana community, banboo community, shurb community. Vertical structure was composed of three layers, including tree layer, shrub layer and herb layer. Species in shrub layer was the richness. P. massoniana is the only dominant species of the community, it can not regenerate naturally, the shrub layer has a greater effect on the community of L. gracile in the future. In addition, the banboo community and shurb community is not stable because of human's activity. Therefore, the community characters of L. gracile should be taken care of conservation when the resources are utilized.

BACKGROUND: The effect of pituitary adenylate cyclase activating polypeptide (PACAP) during traumatic brain injury (TBI) and whether it can modulate secondary injury has not been reported previously. The present study evaluated the potential protective effects of ventricular infusion of PACAP in a rat model of TBI. METHODS: Male Sprague Dawley rats were randomly divided into 3 treatment groups (n=6, each): sham-operated, vehicle (normal saline)+TBI, and PACAP+TBI. Normal saline or PACAP (1g/5L) was administered intracerebroventricularly 20 minutes before TBI. Right parietal cortical contusion was produced via a weight-dropping method. Brains were extracted 24 hours after trauma. Histological changes in brains were examined by HE staining. The numbers of CD4+ and CD8+ T cells in blood and the spleen were detected via flow cytometry. RESULTS: In injured brain regions, edema, hemorrhage, inflammatory cell infiltration, and swollen and degenerated neurons were observed under a light microscope, and the neurons were disorderly arrayed in the hippocampi. Compared to the sham group, average CD4+ CD8– lymphocyte counts in blood and the spleen were significantly decreased in rats that received TBI+vehicle, and CD4– CD8+ were increased. In rats administered PACAP prior to TBI, damage was attenuated as evidenced by significantly increased CD4+, and decreased CD8+, T lymphocytes in blood and the spleen. CONCLUSION: Pretreatment with PACAP may protect against TBI by influencing periphery T cellular immune function.

UNLABELLEDThis study is conducted to explore an effective culture method for supporting the embryo development. The cattle fetal ear fibroblasts and the goat fetal ear fibroblasts are transplanted into the enucleated cattle oocytes separately by oocyte intraplasmic nuclear injection method to construct bovine cloned embryos and goat-bovine cloned embryos. The embryos are first cultivated in modified charles rosenkrans 2 amino acid medium (mCR2aa) and modified synthetic oviduct fluid medium (mSOF) separately. Then BSA (8 mg/mL) or FBS (10%) can be added to mSOF according to the different culture period. The supplements and orders, added during the first three days and after three days are as follow: BSA and BSA, BSA and FBS, FBS and BSA, FBS and FBS. On the basis of the cleavage rate, 8/16-cell rate, blastocysts rate and total cell number of blastocysts, the best culture way can be screened out.

RESULTFirst, cleavage rate, 8/16-cell rate, blastocysts rate and total cell number of blastocysts, cultivated in mSOF solution are all higher than those cultivated in mCR2aa( P < 0.05). Second, the cleavage rate and 8/16-cell rate, adding BSA and FBS into mSOF, are in turn 79.8% +/- 7.1%, 49.7% +/- 3.5%, 21.5% +/- 1.8%, and 115.2 +/- 4.3 in bovine cloned embryo, and 40.1% +/- 6.3%, 29.2% +/- 2.0%, 13.4% +/- 2.1% and 100.1 +/- 3.0 in goat-bovine cloned embryo, which are significant higher than other culture groups (P < 0.05).

CONCLUSIONThe goat-bovine cloned embryo can be cultivated by the optimized culture measure of bovine cloned embryo. The best culture ways of bovine cloned embryo and goat-bovine cloned embryo are all to use mSOF supplemented BSA in the first three days and then use mSOF supplemented FBS in the next five days.

The complex field cure instrument is a new medical instrument with which an experiment was carried out. Rats were continuously irradiated by the complex field for 90 days, with a day's total dose of 285.9 M.T.G. while other rats weren't irradiated for control group. The animals were respectively killed at 7d, 14d, 30d, 60d and 90d, and their blood samples were taken for cell and humoral immune analysis. The results show that values of lymphocyte transform rate, soluble receptor (SIL-2R), total hemolytic complement levels (CH50) and immunoglobulin (A.G.) after irradiation are more than those of the control group having proved that the instrument may improve immune function of rats.
