Objective:After using proximal femoral nail antirotation (PFNA) fixation to treat femoral intertro-chanteric fractures (ITFs), closed negative pressure drainage systems are often used for drainage, but the clinical effect of this method is uncertain. A prospective randomized controlled trial study was conducted to analyze the negative effects of negative pressure drainage systems after PFNA fixation.Methods:Sixty patients with ITFs and underwent PFNA fixation were randomly divided into two groups. Patients in the drainage group were equipped with negative pressure drainage systems after PFNA fixation. At 4, 10, and 90 days after the surgery, the visual analog scale (VAS) score, analgesic dosage, thigh swelling width, wound and infection status, hemoglobin, hematocrit level, total blood loss and transfusion blood volume of the patients were recorded to evaluate the prognosis.Results:The total blood loss of the drainage group [(579.1±236.7) ml] was greater than that of the non-drainage group [(427.8±239.8) ml; P=0.01]. The transfusion blood volume of the drainage group [(443.3±176.3) ml] was greater than that of the non-drainage group [(307.8±155.4) ml; P=0.01]. Compared with the non-drainage group, the drainage group had a higher VAS score at 4 days after the surgery (2.3±0.6, P=0.02). There was no difference between the two groups in analgesic dosage, thigh swelling width, wound infection and hematoma, hospital stay and the total number of complications (all P>0.05). Conclusions:In the patients with ITFs treated with PFNA fixation, the transfusion blood volume and total blood loss of the patients in the drainage group are higher than those in the non-drainage group. In addition, drainage systems may not have short-term benefits for postoperative wound conditions.

The status of marine bioresources and the marine eco-environment issues were summarized and discussed, and the strategies for the development of Chinese marine bioresources in the future were proposed. The degradation of marine eco-environment and unreasonable exploitation of the resources resulted in acute decline of Chinese marine bioresources. The feasible stratagies for the sustainable use of marine bioresources should be to intensify the basic research on marine bioresources science, to strengthen the protection of the marine environment and conservation of marine living resources, and to exploit and utilize marine bioresources scientifically and reasonably by using high-technology including marine biotechnology.

Objective To analyze the clinical features of patients with prostate adenocarcinoma under 50 years.Methods Between January 2008 and April 2014,we reviewed 21 cases with prostate cancer under 50 years old.The mean age in those patients was 48 years old (ranged 42-49 years old).Their tPSA level was elevated,including＞10 μg/L in 17 cases,4-10 μg/L in 4 cases.21 cases were all confirmed by pathology.The results Gleason score showed 6 scores in 3 cases,7 scores in 6 cases (3+4 scores in 5 cases and 4+3 scores in one case),8 scores in 7 cases and 9 scores in 5 cases.In the study,clinical stage was for T2N0M0 in 16 cases,T3N0M0 in 1 case,T4NxM0 in 1 case and T3-4N1M1 in 3 cases.The treatments were hormonal therapy was chosen in 5 cases and radical prostatectomy was performed in 16 cases,including 16 cases with T2N0M0 stage and one case with T3N0M0.Results In those patients who accepted the radical prostatectomy,the duration of follow-up ranged from 3 to 65 months (mean 23 months).During the follow-up,14 patients had a lower incidence of biochemical recurrence.1 patient (T2,PSA 82.8 μg/L,GS 9) had external beam radiotherapy one month after the radical prostatectomy because of tumor invasion into the prostatic capsule.Then his PSA level returned to the 0.2 μg/L.1 patient (T3,PSA 38.9 μg/L,GS 8) had external beam radiotherapy 18 months after the radical prostatectomy because of biochemical recurrence and the tPSA level returned to the 4.0 μg/L.All patients who underwent radical prostatectomy had favourable recovery of urinary continence.In 5 patients who had androgen deprivation therapy,2 patients died after 63 or 65 months and one patient was lost to follow-up.The PSA level in one patient decreased from 71.8 μg/L to 2 μg/L after four months treatment.One patient had castration resistant prostate cancer and the adjuvant external beam radiotherapy was considered,subsequently.Conclusions Men under the 50 years old,who are diagnosed with localised prostate cancer,usually demonstrated the early clinic stage and high Gleason scores.It should not be discouraged from RP.Young men with metastatic prostate cancer have a poor prognosis.

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.

OBJECTIVETo investigate the antitumor activity of Diosgenin in vivo and in vitro.

METHODS-180, HepA, U14 and EAC transplant mice were given Diosgenin ig or i.p. everyday for 10 days, from the next day when they were inoculated in axilla. Tumor growth inhibit rates were calculated. Four kinds of cells, MCF, L929, A375-S2 and HeLa, were incubated respectively with Diosgenin in vitro. Tumor growth inhibit rates were also calculated.

RESULTIn vivo, both ig and i.p., Diosgenin inhibited S-180, HepA, U 14 mice transplant tumor, the inhibit rates being 30%-50%, but it did not inhibit the EAC mice transplant tumor. In vitro, Diosgenin inhibited L929, HeLa, MCF cell growth, and IC50 were 1.2, 18.2, 19.8 micrograms.mL-1 respectively, but it did not significantly affect A375-S2 cells.

CONCLUSIONDiosgenin has an obvious antitumor activity on S-180, HepA, U14 transplant mice in vivo and L929, HeLa, MCF cells in vitro.

OBJECTIVETo evaluate the inhibitory effect of recombinant adenovirus carrying human endostatin gene (Ad-endo) on the growth of human pancreatic carcinoma xenograft in nude mice.

METHODSThe expression of endostatin in human pancreatic carcinoma Capan-2 cells was examined by RT-PCR after infection with Ad-endo. The supernatants of Capan-2 cells were collected after 48 h of infection with Ad-endo as the conditioned medium for human umbilical vein endothelial cells (HUVECs), whose proliferation in vitro was assayed. Capan-2 cell xenografts were established to determine the antitumoral effects of Ad-endo in vivo. The intratumoral microvessel density (MVD) was evaluated using CD31 staining.

RESULTSThe expression of endostatin gene was detected by PT-PCR in infected Capan-2 cells. The conditioned medium from Ad-endo-infected cells significantly inhibited HUVEC proliferation (P<0.05). Ad-endo significantly suppressed the growth of Capan-2 tumor xenografts in nude mice (P<0.05), and the MVD decreased significantly in the treated tumor (P<0.05) as compared with that in the control group.

CONCLUSIONAdenovirus carrying human endostatin gene produces inhibitory effects on the growth of human pancreatic carcinoma tumors in nude mice.
