After the origin, definition and functions of core journal were described, scientifically understanding their value and accurately defining their functions were proposed.The current evaluation of military sciences core journals was analyzed with measures put forward for perfecting their evaluation systems.

Objective To explore the clinical application value of whole-brain CTA-CTP imaging in cerebral arteriovenous malformation (cAVM).Methods Fifteen patients diagnosed with cAVM by CTA-CTP imaging were included in this retrospective analysis study. The angioarchitecture of cAVM lesions were recorded from 4D-CTA images.Using DSA as the golden standard,the diagnostic accuracy of 4D-CTA was evaluated in 13 cases.The perfusion patterns of vessel nidus and peritumoral tissues were analyzed from the CTP images.Bleeding ratios of patients with different angioarchitecture and perfusion patterns were compared.Results 4D-CTA could dynamically display the angioarchitecture details of cAVM lesions and show the whole process of the contrast agent in and out of the vessel nidus.Although the result of 4D-CTA was consistent with that of DSA in most cases,a few fine feeding arteries and draining veins were missed.The nidus in thirteen cases was with high perfusion and the peritumoral tissues were with low perfusion.Another two cases were with low perfusion due to the presence of hematoma.Nine cAVMs suffered from small size,single feeding artery,deep venous drainage and vessel nidus with increased MTT,peritumoral tissues with decreased MTT were more likely to suffer a hemorrhage (P<0.05).Conclusion Whole-brain CTA-CTP imaging could be a valuable adjunct in noninvasive diagnosis of cAVM and predicting the bleeding risk factors.

OBJECTIVE: To evaluate the utilization and its trend of narcotic analgetics in this hospital.METHODS: The use of narcotic analgetics during the period 2005-2007 in our hospital was analyzed retrospectively.RESULTS: The consumption quantity of narcotic analgetics in our hospital increased year-on-year,much as in the consumption of morphine preparations,with oral morphine preparations dominating the 3 first places over the 3 years,however,the increase of pethidine was slowed down in consumption quantity.CONCLUSION: The use of narcotic analgetics in our hospital is rational on the whole,but measures should be taken to tighten the control on the use of narcotic analgetics.

OBJECTIVE:To validate the microbial limit tests of Shuanghuanglian oral liquid.METHODS:The recovery rates of 4 kinds of test organisms including E.coli treated by Shuanghuanglian oral liquid were detected by routine method,culture medium dilution method,and membrane-filter procedure respectively.RESULTS:Shuanghuanglian oral liquid was found to be of bacteriostatic action.The contamination of solution couldn't be detected by routine method.The recovery rate of the test organisms detected by membrane-filter procedure was higher than by culture medium dilution method,but the recovery rates in both methods were all up to the requirement.CONCLUSION:Membrane-filter procedure should be considered preferentially in performing microbial limit test for Shuanghuanglian oral liquid.

An innovative approach,named associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),has made possible a marked increase in future liver remnant (FLR) over a short period of time,and has challenged the concept of unresectability.To date,ALPPS has been employed for a variety of primary and metastatic liver tumors from many centers across the world.Many technical variations of ALPPS have been described.However,much controversy has surrounded this procedure,and many problems remain to be solved,such as the reasons for rapid hypertrophy,the technical feasibility,safety and long-term oncologic outcomes,and the result compared with the conventional two-stage hepatectomy.These aspects are needed to be evaluated further in large-scale studies.We believe that the ALPPS procedure will has much room for further development.

The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.

LDM, a product of the combination of contemporary information network technology and the traditional medical mode, is a rapidly developing new undertaking of recent years. The transformation of the medical mode in the establishment of LDM has brought about a series of problems, including quality control of LDM, delegation of responsibility in LDM, standardization and unification of LDM, and psychological problems of patients under the mode of LDM. These problems present issues of new conternplation and exploration for hospital managers.

Objective:To study the HBV infection in peripheral blood mononuclear cells in mediating the role of mother -to-child transmission of hepatitis B virus.Methods: The peripheral blood mononuclear cells ( PBMCs ) in maternal and cord blood mononuclear cells ( CBMCs ) in newborns were conventionally isolated by Ficoll-Hypaque medium.The loads of HBV-DNA in peripheral blood of maternal and cord blood of newborns were both detected by PCR .Results:The clinical data showed that the positive detection rates of HBV-DNA in serum and PBMCs of pregnant women with HBeAg (+) were 100.00%( 25/25 ) and 72.00%( 18/25),and the positive detection rates of HBV-DNA in the neonatal umbilical cord blood serum and CBMCs were 60.00%(15/25) and 44.00%(11/25),respectively.There were significantly difference between HBeAg (+) and HBeAg(-) in the pregnant women (P<0.05 ).The positive detection rates of HBV-DNA in neonatal umbilical cord blood serum and CBMCs were higher in the group with high HBV loads (more than 106copies/ml) in PBMCs than those of low HBV loading group (102-103copies/ml).The significantly difference was explored between the two groups.Conclusion: Mononuclear cells can not only be infected by HBV , but also play a critical role in the intrauterine vertical transmission of HBV via the pathway transmitted from PBMCs in pregnant women to CBMCs in newborns.

Objective To evaluate the risk factors of gallstone occurrence after gastrectomy for gastric cancer.Methods Relevant documents published from 1990 to 2014 were retrieved through Pubmed,Cochrane Library,Embase,Web of Science CNKI,Wan Fang and VIP databases search.The Meta-analysis was applied with RevMan 5.3 software for Odds ratio and 95％ CI.Results 24 studies were selected for this Meta-analysis which included 3 randomized controlled trials,13 cohort studies and 8 case-controlled studies.These 24 studies included patient number which ranged from 32 to 893.The pooled OR (95％ CI) and P values of OR (95 ％ CI) for physiologic digestive tract reconstruction were 0.53 (0.44 ～ 0.65,P ＜ 0.05) ;amount of resection of stomach,1.98 (1.29 ～ 3.04,P ＜ 0.05) ; lymphadenectomy,0.38 (0.21 ～ 0.72,P ＜ 0.05) ; vagotomy,0.24 (0.13 ～ 0.45,P ＜ 0.05) ; and pylorus preservation,0.70 (0.48 ～ 1.02,P ＞ 0.05).Conclusions Physiologic digestive tract reconstruction and vagus nerve preservation reduced occurrence of gallstones after gastrectomy.On the other hand,total gastrectomy and extensive lymph node dissection increased the occurrence.There was no significant difference in the occurrence of gallstones whether there was pylorus preservation or not.

LDM, a product of the combination of contemporary information network technology and the tradi tional medical mode, is a rapidly developing new undertaking of recent years. The transformation of the medical mode in the establishment of LDM has brought about a series of problerms, including quality control of LDM, delegation of responsibility in IDM, standardization and unification of LDM, and psychological problems of patients under the mode of LDM. These problems present issues of new contemplation and exploration for hospital managers.
