Objective To investigate the preventive effect of oral ulcer using two methods in radio-therapeutic patients after tongue squamous cell carcinoma operation. Methods Thirty-six radiotherapeutic patients after tongue squamous cell carcinoma operation were collected from May 2012 to May 2014 and divided into control group and treatment group according to the random number table method. Regular oral nursing was administered to control group, treatment group were received regular therapy plus orally vitamin B and cetylpyridinium chloride gargle for gargling, and then evaluated the efficacy according related standards. Results Less oral ulcer (1/18 vs.7/18,χ2=-2.372,P<0.05), better oral lustration (Z=-2.093,P<0.05) and overall oral nursing effect (Z=-2.166,P<0.05) were observed in treatment group compared to control group after 7 days of therapy, however, treatment group presented no significantly better comfort level at the same time (Z=-1.708,P>0.05). Conclusions Regular therapy plus orally vitamin B and cetylpyridinium chloride gargle for gargling are effective for the prevention of oral ulcer in radiotherapeutic patients after tongue squamous cell carcinoma operation.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.
METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.
RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.
CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

Objective To analyze the surgical technique of extraperitoneal laparoseopic radical prostatectomy with neurovascular bundle preservation and its effect on micturition control and sexual function in patients with prostate cancer. Methods Twenty-two patients with a median age of 66. 9 years underwent extraperitoneal laparoscopic radical prostatectomy with neurovascular bundle preservation from October 2005 to March 2009 in our hospital and Shanghai Changzheng hospital. All patients had no erectile dysfunction. According to the pathology, there were 2 cases of PIN high grade, 4 cases of Tla-b, 9 cases of Tlc, 4 cases of T2a-b, 2 cases of T2e and 1 case of T3a. Results All operation were successful and no case was conversed to open surgery. The average operation time was 225 min and the mean blood loss was 850ml. The amount of blood loss in 1 case was 1200 ml because of injuring deep dorsal vein of penis. 4 cases received blood transfusion, gatheters of all patients were removed 2 weeks after operation, and three cases with mild incontinence regained continence of urine after 6 months follow-up. No patient occurred postoperative vesicourethral anastomotic leakage of urine. The surgical margin of 1 case was positive. No biochemical index of prostatl cancer recurred during postoperative follow-up of 10-24 months (with an average of 16 months). 20 cases had sexual function recovery after operation. Conclusions The extraperitoneal laparoscopie radical prostatectomy with neurovascular bundle preservation for prostate cancer is a safe and effective treatment method with less bleeding, small damage and less complications. It can guarantee the maximum of micturition control and sexual function, which is worthy to be popularized in the clinic.

OBJECTIVETo study the cardiovascular effects of magnesium lithospermate B (MLB), a water soluble extract from red sage root, on human aortic endothelial cells (HAECs) proliferation and in treating free radical injured endothelial cells, so as to further understand the cardiovascular pharmacological mechanism of MLB.
METHODSHAECs of 3-6 passages were used in the experiment. MLB of different concentrations was used to treat the cells, and cell proliferation was observed using morphological and MTT method. The free radical injured model cell was made by glucose-glucose oxidase method for observing the effect of MLB on its microstructure by transmission electron microscopy.
RESULTSMLB in concentration of 1.0 mg/ml and 0.5 mg/ml had significant cytotoxicity (P<0.01), when its concentration was lower than 0.2 mg/ml, the drug showed no adverse reaction on cell proliferation. MLB showed significantly cell protective effect against free radical injury, the effect in protecting ultrastructure of cells, such as mitochondria, could be demonstrated in transmission electron microscopy.
CONCLUSIONMLB showed a low cytotoxicity on HAECs, it could obviously protect cells from free radical injury.

OBJECTIVETo investigate the influence of autophagy on the survival and proliferation of multiple myeloma (MM) cells.
METHODSMultiple myeloma (MM) cell line U266 cell autophagy was induced by serum-free culture condition, and adding rapamycin or 3-MA respectively. The cells proliferation was observed. U266 cells, lymphoma cell Jurket under normal culture condition, and serum-free cultured Jurket cell were used as control group. The proliferation and apoptosis of cells were determined by CCK8 and flow cytometry, respectively. MDC staining were employed to detect the autophagy. The mRNA expression of Mtor and Beclin1 gene of U266 cells were assayed by RT-PCR. Protein LC3I/LCII and LAMP1 was analyzed by western blot.
RESULTSThere was low level of autophagy in U266 cells, sera starvation increased the level of autophagy. Rapamycin upregulated autophagy of the U266 cells and stimulated their proliferation. But the autophagy level of sera starvation and rapamycin group declined when culture for 96h.3-MA had the same effects on U266 cells, although it was on 24 h. But rapamycin and 3-MA could inhibit cell proliferation under normal culture condition. Compared with normal culture condition, apoptosis of U266 cells increased significantly after 24h incubation in medium without sera \[(1.33 ± 0.09)% and (17.90 ± 1.46)%, respectively\] (P < 0.01). Rapamycin and 3-MA could inhibit the serum-free induced apoptosis \[(6.23 ± 0.12)% and (6.97 ± 0.03)%, respectively\](P < 0.01), but cell apoptosis was at the same level after 72 hour incubation \[(30.37 ± 0.27)%, (30.13 ± 1.93)% and (28.57 ± 2.83)%, respectively\] (P > 0.05). However, apoptosis of U266 cells decreased to 18.7% and 12.6% after removal of rapamycin and 3-MA.
CONCLUSIONThere is basically level of autophagy in MM cells which is higher than those in the Jurkat cells. Both Rapamycin and 3-MA can inhibit the cells proliferation under normal culture condition. Up-regulated autophagy promotes survival and proliferation of MM cells under sera deletion. Rapamycin strengthens this effect with limited duration. 3-MA has dual effects on cell autophagy.

OBJECTIVETo elaborate on the angiographic classification of central arteriovenous malformations (AVMs) in jaws, and to evaluate the correlation between this classification and treatment options.
METHODSX-ray films and angiograms of 25 cases with AVMs in the jaw were retrospectively reviewed to evaluate the appearance of radiolucency, feeding arteries, nidus of the malformations and draining veins. Based on the findings a classification of angioarchitecture was recommended. Furthermore, the treatment results of these cases were reviewed to assess the correlation between this classification and treatment options.
RESULTSThe angiographic pictures of 25 cases with central AVMs could be divided into five types: type I (n = 5) was with merely diffused micro-arteriovenous fistulas (AVFs); type II (n = 8) demonstrated a large venous pouch, all the feeding arteries drained into it; type III (n = 7) had a large venous pouch together with diffused micro-AVFs (I + II); type IV (n = 2) had multiple venous pouches; type V (n = 3) had multiple venous pouches and diffused micro-AVFs (I + IV). The angioarchitecture corresponded well to the radiographic appearance in all except one case. With respect to the treatment, type II, III, IV AVMs gained clinical cure in 100% of cases, whereas type I and type V AVMs obtained clinical cure only in 3 of 5 and 1 of 3 cases respectively.
CONCLUSIONSCentral AVMs in jaws exhibited variant patterns of angioarchitecture, which could be divided into five types. Elaboration of this classification was helpful for decision-making on choosing appropriate therapy.

OBJECTIVETo explore the relationship between the polymorphism of TNF-α gene 308, 238 locus and the susceptibility to pneumoconiosis.
METHODSEighteen published case-control studies about TNF-α gene 308, 238 locus polymorphism and pneumoconiosis susceptibility were searched out from sino-foreign databases from January 1994 to December 2010. Meta-analysis was applied on the published research to calculate the pooled OR value (95%CI) and stratified analyze the types and species of pneumoconiosis.
RESULTSEleven of the published research articles were selected into the analysis, including 10 research focusing on TNF-α gene 308 locus, with 1408 cases and 1639 controls in total. The meta-analysis showed that comparing with Gln/Gln carriers, Arg/Arg, Arg/Gln, Gln/Arg + Arg/Arg carriers were 1.89-fold (95%CI: 1.10 - 3.24), 1.53-fold (95%CI: 1.25 - 1.87), and 1.56-fold (95%CI: 1.28 - 1.90) more susceptible to pneumoconiosis, respectively. The stratified analysis showed that among coal workers, the TNF-α gene 308 locus Arg/Arg, Arg/Gln, Gln/Arg + Arg/Arg carriers were separately 2.29-fold (95%CI: 1.22 - 4.29), 1.56-fold (95%CI: 1.20 - 2.03), 1.64-fold (95%CI: 1.28 - 2.11) more susceptible to pneumoconiosis than Gln/Gln carriers; and among Asian people, the TNF-α gene 308 locus Gln/Arg, Gln/Arg + Arg/Arg carriers were separately 1.58-fold (95%CI: 1.28 - 1.95) and 1.57-fold (95%CI: 1.28 - 1.94) more susceptible to pneumoconiosis than the Gln/Gln carriers. Four case-control research focus on the study of TNF-α gene 238 locus, including 391 cases and 391 controls in total. The analysis showed that comparing with the non-carriers, TNF-α gene 238 locus Arg/Arg, Arg/Gln, Gln/Arg + Arg/Arg carriers were 6.03-fold (95%CI: 1.35 - 26.97), 1.87-fold (95%CI: 1.07 - 3.30) and 2.36-fold (95%CI: 1.37 - 4.07) more susceptible to pneumoconiosis.
CONCLUSIONTNF-α gene 308, 238 locus Arg/Arg, Gln/Arg, Gln/Arg + Arg/Arg carriers are more susceptible to pneumoconiosis.
