Objective To evaluate the efficacy and adverse reaction of continuous low-dose oral Tegafur,Gimeracil and Oter-acil Potassium Capsules in combination with small dose of transcatheter arterial chemoembolization(TACE)in the treatment of pri-mary hepatocarcinoma patients.Methods A total of 92 primary hepatocarcinoma patients who were unable or unwilling to surgery. Patients were divided into treatment group and control group,with each consisted of 46 cases.The treatment group was given con-tinuous low-dose oral Tegafur,Gimeracil and Oteracil Potassium Capsules in combination with small dose of TACE,and the control group was given small dose TACE.All study subjects were reviewed DSA and CT.tumor angiogenesis and tumor staining,Karnof-sky Performance Scores(KPS),postoperative adverse events and complications was evaluated.PFS and the survival rate of three months,six months,one year and two years was estimated.Results Tumor angiogenesis and staining were significantly lower in treatment group than those of the control group(P <0.05).Patients in the two groups had the same rates of side effects and com-plications(P >0.05).KPS scores in the two groups had no significant difference before and after treatment(P >0.05 ).PFS,one year and two years survival rate were better in treatment group than in the control group(P <0.05).Conclusion Combined appli-cation of continuous low-dose oral Tegafur,Gimeracil and Oteracil Potassium Capsules and small dose TACE was significantly su-perior to TACE alone in the treatment of primary hepatocarcinoma patients.

OBJECTIVE:To observe the effect of rosuvastatin on prognostic of patients with paroxysmal atrial fibrillation (AF) after circumferential pulmonary vein ablation. METHODS:75 patients with paroxysmal AF were divided into observa-tion group(n=39)and control group(n=36)according to the admission single. All patients underwent circumferential pulmo-nary vein ablation antiarrhythmic treatment. Control group orally received warfarin sodium,amiodarone,metoprolol,and sub-cutaneous injected low molecular weight heparin. Observation group additionally received 10 mg Rosuvastatin tablet,qd on the basic of contol group. Changes of cardiac function,inflammatory factors,lipid levels in 2 groups before and after treat-ment were observed,and follow-up results were compared. RESULTS:There was no significant difference in left atrial diame-ter and left ventricular ejection fraction in 2 groups before and after treatment (P>0.05);atrial effective refractory periods (AERP)in 2 groups significantly prolorged,and observation group prolorged more significantly than control group,the differ-ence was statistically significant(P<0.05). Serum high sensitivity C-reactive protein,interleukin-6 48 h and 1 month after op-eration in 2 groups significantly increased,and control group was significantly higher than observation group,the difference was statistically significant (P<0.05);before operation and after 3 months of operation,there was no significant difference in inflammatory cytokine levels(P>0.05). Triglyceride and low density lipoprotein cholesterol in observation group 1 month after operation significantly decreased, HDL-C significantly increased, there were significant differences (P<0.05). Fol-low-up time was (23.91 ± 5.28) months,AF recurrence was 7.8%,which was significantly lower than control group (13.9%),the difference was statistically significant (P<0.05);and there were no significant differences in ablation-related atrial tachycardia (ATa) and the incidence of adverse reactions between 2 groups (P>0.05). CONCLUSIONS:Rosuvastatin can effectively inhibit the inflammatory reaction and prolong the AERP,thereby reducing the recurrence rate of AF,with good efficacy and safety.

OBJECTIVE:To explore the difference of genotypes in patients with coronary artery disease(CAD)and different responses to clopidogrel. METHODS:Totally 159 CAD patients were selected from cardiology department of our hospital during Mar. 2013-Nov. 2015. They were given clopidogrel+aspirin for dual antiplatelet therapy for at least 1 year. Turbidimetry method was used to detect the percentage of platelet aggregation induced by adenosine diphosphate (ADP) and arachidonic acid (AA) before and after treatment. The polymorphism of cytochrome P450(CYP)2C19,CYP3A5,wild type leucine 33 allele(PLA1)/proline 33 al-lele(PLA2)were detected by PCR-RFLP. RESULTS:There were 3 kinds of CYP2C19 genotypes(2/2,2/1,1/1),3 kinds of CYP3A5 genotypes (3/3,3/1,1/1) and 3 kinds of PLA1/PLA2 genotypes (A1/A2,A2/A2,A1/A1);the frequency of each genotype was in line with Hardy-Weinberg balance(P>0.05). Among 159 cases,there were 81 cases of clopidogrelsemi-re-sponse,accounting for 50.9%;78 cases of clopidogrelresponse,accounting for 49.1%. The frequencies of CYP2C19 gene dele-tion(2/2 or 2/1 genotype)and 2 allele in clopidogrelsemi-responsepatients were significantly higher than clopidogrelre-sponsepatients,with statistical significance(P<0.05). The frequencies of PLA1/PLA2 gene deletion(A2/A2 or A1/A2 genotype) and A2 allele in clopidogrelsemi-responsepatients were significantly higher than clopidogrelresponsepatients,with statistical significance(P<0.05). The frequencies of CYP3A5 gene deletion(3/3 or 3/1 genotype)and 3 allele in clopidogrelsemi-re-sponsepatients were slightly higher than clopidogrelresponsepatients,without statistical significance (P>0.05). After treat-ment,the percentage of ADP or AA-induced platelet aggregation in different genotypes patients were significantly lowered,com-pared to before treatment;but the percentage of platelet aggregation in CYP2C19 gene deletion and CYP3A5 gene deletion patients were significantly higher than gene expression patients(1/1 genotype),with statistical significance(P<0.05). There was no sta-tistical significance in the percentage of platelet aggregation between PLA1/PLA2 gene deletion patients and gene expression patients (P>0.05). CONCLUSIONS:The incidence of clopidogrelsemi-responsein CAD patients is high. CYP2C19 and PLA1/PLA2 gene polymorphism may be related to clopidogrelsemi-re-sponse,while CYP3A5 gene polymorphism has no relation-ship with it. CYP2C19 and CYP3A5 gene deletion may weaken inhibitory effects of clopidogrel on platelet aggregation of CAD patients.

Objective To compare the clinical outcomes between conventional percutaneous vertebroplasty (PVP) and targeted PVP in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods A retrospective cohort study was designed to review 215 cases of single level OVCFs hospitalized between January 2014 and December 2015.According to the procedure techniques,the patients were assigned to targeted PVP group (89 cases) and conventional PVP group (126 cases) which was further divided into sufficient filled subgroup (110 cases) and insufficient filled subgroup (16 cases) on basis of cement distribution.Key techniques of targeted PVP included accurate needle insertion to fractured area and cement injection using a push rob with a side opening.Operating time,cement injection volume,rate and types of cement leakage,cement distribution in the fractured area and visual analogue score (VAS) of back pain were compared between the two groups.Results Operating time in targeted PVP group was longer than that in conventional PVP group (P ＜ 0.05).There were no significant differences in cement injection volume and rate and types of cement leakage between the two groups (P ＞ 0.05).None in targeted PVP group showed insufficient cement distribution in fractured area,while 16 cases (12.7％) in conventional PVP group (P ＜ 0.05).No significant differences in preoperative VAS of back pain existed among targeted PVP group,sufficient subgroup and insufficient subgroup (P ＞ 0.05).VAS of back pain was significantly decreased after PVP in three groups (P ＜ 0.05).Difference in postoperative VAS of back pain between targeted PVP group and sufficient filled subgroup was insignificant (P ＞0.05).However,postoperative VAS of back pain in insufficient filled subgroup was significantly increased compared with targeted PVP group and sufficient filled subgroup (P ＜ 0.05).Conclusion Targeted PVP provides sufficient cement to fill the fractured area and decreases incidence of unsatisfactory clinical outcome compared with traditional PVP,indicating a secure and effective new technique in the treatment of OVCFs.

OBJECTIVETo study subtype classification of gastric neuroendocrine neoplasm (NEN) and their clinicopathological characteristics in order to provide reference for clinical practice.

METHODSClinicopathological data of 241 gastric NEN patients (174 cases from China-Japan Friendship Hospital and 67 cases from The First Affiliated Hospital of Sun Yat-Sen University) between January 2011 and June 2016 were retrospectively summarized. According to serum gastrin, 24-hour intragastric pH monitoring and pathological grade, patients with gastric NEN were divided into 4 types: type I( (hypergastrinemia and achlorhydria, related to autoimmune chronic atrophic gastritis), type II( [hypergastrinemia and Zollinger-Ellison syndrome, related to gastrinoma or multiple endocrine neoplasia type I( (MEN-I()], type III( (sporadic disease with normal serum gastrin level), and type IIII( [poorly differentiated gastric neuroendocrine carcinoma (NEC) and mixed adenoneuroendocrine carcinoma (MANEC)]. Clinicopathological features, treatment and prognosis of 4 types were analyzed.

RESULTSOf 241 gastric NEN cases, there were 86 cases (35.7%) in type I(, 7 cases (2.9%) in type II(, 61 cases (25.3%) in type III( and 87 cases(36.1%) in type IIII(. Among 86 cases of type I( gastric NEN, 73 cases (84.9%) were multiple lesions,tumor size of 66 cases (76.7%) was less than 1 cm, all the 86 cases were polypoid or granular lesions. 2 cases(2.3%)presented distant metastasis, 69 cases (80.2%) had pathological grading as NET G1; most of them received endoscopic surgery treatment and follow-up; somatostatin analogs(SSA) was used in patients with multiple lesions and repeated recurrence after endoscopic treatment. Among 7 cases of type II(, 4 cases were gastrinoma, 3 cases MEN-I(; 5 cases presented distant metastasis; treatment included surgery, SSA and proton pump inhibitor (PPI) therapy. Among 61 cases of type III( gastric NEN, 49 cases(80.3%) were single lesion,tumor size of 25 cases(41.0%) was more than 2 cm, 29 cases(47.5%) had lymph node metastasis or distant metastasis; treatment included endoscopic resection, surgery or SSA therapy according to the tumor staging. Among 87 patients of type IIII( gastric NEN, 74 cases(85.0%) had single lesion,tumor size of 51 cases (58.6%) was more than 2 cm; lesions were found in gastric cardia in 35 cases (40.2%); 65 cases (74.7%) had lymph node metastasis or distant metastasis; treatment included chemotherapy, or surgery plus chemotherapy. At the end of follow-up(June 30, 2016), 58 patients were dead, including 1 case of type I(, 12 cases of type III( and 45 cases of type IIII(. The overall survival rate of all the patients was 74.2%, and was 98.8%, 100%, 79.3%, 39.2% of types I(, II(, III(, IIII( respectively. The overall survival rate between type III( and type IIII( gastric NEN was significantly different(P = 0.000).

CONCLUSIONSSubtype classification of gastric NEN is very significant for making therapeutic decisions and prognostic evaluation. Patients of type I( or type II( gastric NEN have good prognosis,while those of type III( and type IIII( have poor prognosis, and those of type IIII( have the worst prognosis.
