OBJECTIVETo investigate the feasibility and clinical effect of the extended reverse digital artery island flap including dorsal digital nerve.

METHODSSince 2001, 7 cases of pulp and digital palm defects were repaired by the extended reverse digital artery island flap including dorsal digital nerve.

RESULTSAll the flaps survived. Follow-up showed satisfactory results functionally and cosmetically with 2-PD of 6-9 mm.

CONCLUSIONSThe extended reverse digital artery island flap is a safe and feasible and an effective method for repair of finger pulp defects.

OBJECTIVETo evaluate the radiosensitivity and toxicity of sodium glycididazole and cisplatin in concurrent chemoradiotherapy for local advanced nasopharyngeal carcinoma (NPC).

METHODSSixty patients with local advanced NPC (T3-4N2-3M0) were randomly divided into chemoradiotherapy group (n=30) and chemoradiotherapy plus sodium glycididazole group (n=30). All the patients received radiotherapy with (60)Co or 6-8 MV linear accelerator and concurrent injection of cisplatin at a weekly dose of 20 mg/m square. In sodium glycididazole group, the patients received injections of sodium glycididazole at 800 mg/m square prior to the radiotherapy 3 times a week.

RESULTSAt the end of the therapy and 3 month after the radiotherapy, a response rate of 100% was achieved in both of the groups. But at the end of the therapy, the chemoradiotherapy plus sodium glycididazole group showed a significantly higher rate of complete tumor remission than the chemoradiotherapy group (93.3% vs 73.33%, chi(2)=4.32, P=0.038). The patients in the two groups showed similar tolerance of the therapy during the observation.

CONCLUSIONSodium glycididazole plus cisplatin can accelerate the tumor remission and improve the complete remission rate in patients with local advanced NPC without causing severe toxicity.

OBJECTIVETo investigate the correlation of prolactin receptor (PRL-R) expression to estrogen receptor (ER) and progesterone receptor (PR) expressions in primary breast cancer.

METHODSFor 130 female patients with breast cancer (median age 46 years), PRL-R expression in the primary tumor was detected by immunohistochemistry, and the correlation between PRL-R and ER/PR expressions was analyzed statistically.

RESULTSPRL-R positivity in the primary tumor was found in 89 of the patients (68.5%), and the positivity rate for PRL-R was positively correlated to ER expression (P<0.05). Further stratification of the patients according to the CerbB-2 status revealed such a correlation only in CerbB-2-positive patients (P<0.05). In the patient cohort, no significant correlation was found in the positivity rate between PRL-R and PR expressions (P>0.05), but in CerbB-2-positive patients, the positivity rate of PRL-R showed a positive correlation to PR expression (P<0.05).

CONCLUSIONThe positive correlations in positivity rate between the PRL-R and ER/PR expressions are found only in CerbB-2 positive patients with breast cancer, and the expressional status of CerbB-2 affects the correlation between PRL-R and ER/PR expression in breast cancer.

Objective To propose time-effect standards and standard treatment measures for battlefield extremity injuries.Methods By conducting retrospective analysis of battlefield extremity injuries in the militariy in different countries using literature retrieval and comparative analysis,time-effect standards and standard technical measures of battlefield extremity injuries were outlined.Results In wars of conventional weapons,extremity injuries are the most prevalent.Such treatment should give top priority to the timing of rescue and be implemented in conjunction with the injury classification.Conclusion Time-effect standards and standard treatment measures for battlefield extremity injuries are proposed to strengthen the time-effect treatment capacity of battlefield extremity injuries.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.
