The traditional distal pancreatosplenectomy (DPS) has been the standard surgical procedure for the treatment of resectable pancreatic carcinoma of body and tail.With the development of medical technology,however,the results including the rate of R0 resection,number of lymph nodes dissected and postoperative 5-year survival rate were not significantly improved after DPS.According to pancreatic anatomy and phylembryogenesis,combined with renewed tumor treatment concept,the radical antegrade modular pancreatosplenectomy (RAMPS) was put forward after continuous exploration of pancreatic surgeons to improve prognosis of patients with pancreatic carcinoma of body and tail.Compared with DPS,RAMPS has advantages of R0 resection rate and regional lymphadenectomy and might become the standard surgical procedure.

As long non-coding RNA (LncRNA) research boom,Maternally Expressed Gene 3(MEG3) as LncRNA family is also a widespread concern.MEG3 not been studied in benign disease,and malignant disease more and more in-depth research.MEG3 because of the uniqueness of the tumor suppressor much attention in cancer research,but its specific mechanism of action of tumor suppressor and associated pathways have not been yet entirely clear,remains to be further research and clarify.This article will be now anticancer activity MEG3 and related Pathway summarized.

Objective To explore the clinical efficacy of ALIMTA (pemetrexed disodium) plus cisplatin.Methods Patients with malignant mesothelioma were allocated to two treatment groups envelope:pemetrexed plus cisplatin (PEM-group) or cisplatin alone (DDP-group).Results A total of 64 patients were randomly assigned and evaluated.The number of patients in PEM- and DDP-group had a significant pathologic complete response were (56.25 ％ vs 21.88 ％,x2 =7.943,P ＜0.05).Progression-free survival was significantly higher in PEM-group (P ＜0.05),and 2-year survival rate was lower in DDP-group (P ＜0.05).Conclusion Pemetrexed elicit significant tumor response and delays disease progression compared with DDP alone in patients with advanced MPM.Improvement in OS is seen in this study.

[Objective]A new device of gear-distraction plate (GDP) for spine reduction and fixation was designed and its biomechanical characteristics was evaluated.[Method]The GDP implants were made of titanium alloy (TC4,Ti6AL4V) and the instruments were made of stainless steel after design.Eighteen fresh calf lumbar specimens were randomly divided into three groups, the GDP group had a biomechanical test contrast to control group(CD, Steffee) in load-responsive change, load-displacement, strength, stiffness, torsion intensity and ultimate strength.[Result]Results It is better than control group in load-responsive change, load-displacement, strength, stiffness, torsion intensity and ultimate strength, there was a significant difference between them (P

Objective To evaluate the diagnostic accuracy of GenoType? M TBDRsl for the resistance to fluoroquinolones anti‐tuberculosis drugs .Methods Systematic and comprehensive literature was searched in PubMed ,Embase ,Web of Science ,CBM , CNKI ,VIP and Wanfang database .The relative studies of GenoType? MTBDRsl to fluoroquinolones anti‐tuberculosis drugs were included .After quality assessment ,Meta‐Disc1 .4 software was used to analyze the data .Results A total of 16 trials ,involving 1 766 participants ,were included .The results of Meta‐analysis showed that the weighted sensitivity ,specificity ,positive likelihood ra‐tio ,negative likelihood ratio ,diagnostic odds ratio ,and the area under summary receiver operation curve were 0 .83 ,0 .96 ,17 .50 , 0 .20 ,108 .46 and 0 .934 9 ,respectively .Conclusion GenoType? M TBDRsl assay for the resistance to fluoroquinolones anti‐tuber‐culosis drugs might be with high sensitivity and specificity ,which could be recommended as efficacy diagnostic tool .

Objective To evaluate the protective effects of methylprednisolone combined with dexmedetomidine of cardiac valve replacement in patients with brain cognitive function under cardiopulmonary bypass (CPB).Methods Sixty patients for heart valve replacement in Affiliated Hospital.Inner Mongolia Medical University were randomly divided into four groups (n =15 each):group A control,methylprednisolone group (group M),dexmedetomidine group (Group D) and methylprednisolone combined with dexmedetomidine group (group B).After the induction of anesthesia,the patients were endotracheally intubated and mechanically ventilated.Methylprednisolone 20mg/kg was administered to the CPB circuit prime in group M.A loading dose of dexmedetomidine 1 μg/kg was pumped intravenously over 10 minutes after induction,followed by continuous infusion at 0.05μg/(kg · h) until the end of operation in group D.A loading dose of dexmedetomidine 1 μg/kg was pumped intravenously over 10 minutes after induction,followed by continuous infusion at 0.05μ g/(kg · h) until the end of operation and methylprednisolone 20mg/kg was also administered to the CPB circuit prime in group B.At the same time the equal volume of normal saline was given in group A.After induction (T1),CPB instantly (T2),CPB 30min (T3),l0min after CPB(T4),at the end of operation(T5),6h after CPB (T6),the jugular bulb venous blood samples were taken for testing the serum concentrations of interleukin-6 (IL-6),interleukin-10 (IL-10),S100βprotein and neuron-specific enolase (NSE) using the method of ELISA.Simplified mini-mental state examination (MMSE) is used to assess the cognitive function of patients in pre-operation and 2days,3days as well as 7days after operation.Results At T1-6,IL-6,S100 protein and NSE in group M,group D and group B were significantly lower than those in control group,IL-10 was higher than that in control group,and there was significant difference (P ＜ 0.05).In B group at all time points IL-6 、S100 protein and NSE were lower than those in other groups,IL-10 was higher than other groups,and there was significant differences (P ＜ 0.05).The incidence of postoperative cognitive dysfunction in group M,group D and group B was higher than that in control group,and the incidence of cognitive dysfunction in B group was lowest,and there were significant differences (P ＜ 0.05).Conclusion Methylprednisolone and dexmedetomidine can effectively reduce the concentration of IL-6,S100 protein and NSE in cardiopulmonary bypass,reduce brain injury and the incidence of postoperative cognitive dysfunction.The protective effect on cerebral injury is better when using dexmedetomidine combined with methylprednisolone under cardiopulmonary bypass (CPB).

Objective To analyze effect of oxycodone hydrochloride injection preemptive analgesia on serum cellular immune factors and analgesic effect in postoperative patients with humeral fracture surgery.Methods 52 patients treated by surgical treatment of humeral fractures in our hospital were collected.All patients were randomly divided into experimental group and control group,26 cases in each group.Preemptive analgesia drugs were given corresponding, before and 24h after surgery, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), venous blood CD4 +T, CD8 +T cells and CD4 +/CD8 + T levels and analgesic effect were detected in all patients.Results After surgery, compared with control group, the serum levels of TNF-αand IL-6 were lower in experimental group (P<0.05); the venous blood CD4 +T cell and CD4 +/CD8 + T levels were higher(P<0.05), CD8 +T cell level was lower in experimental group (P<0.05);the visual analogue scale(VAS) score was significantly lower in 2,4,6,12 and 24h after surgery in experimental group (P<0.05).Conclusions The oxycodone hydrochloride injection preemptive analgesia can significantly inhibit the increase of the serum TNF-αand IL-6 levels, prevent the decrease of immune function, improve the analgesic effect.

Objective To optimize the prescription and technology of Brucea javanica oil subnanoemulsion injection. Methods Using superfine Brucea javanica oil as oil phase,yolk lecithin and poloxamer 188 as the complex emulsifying agents. The dosage of oil,emulsifier and stabilizer were optimized and the preparation was optimized by orthogonal experiments. Results The optimum precription was 10% oil phase,1.2% emulsifier and 0.1% stabilizer. The optimum technology was that aqueous phase and oil phase mixed at 70 ℃,sheared 20 min by high speed shearing machine and then passed the ultra-high pressure nano homogenizer 6 times under the pressure of 900 bar. Conclusion The physical stability of Brucea javanica oil subnanoemulsion injection is good.
