Objective To observe the protective effect of goserelin on ovarian function of premenopausal patients with breast cancer during chemotherapy. Methods Forty patients with breast cancer under 40 received adjuvant chemotherapy were randomly divided intotest group(20 cases) and control group (20 cases). Compared the recovery rate and time of menstruation between two groups. Results All the 40 patients finished the treatment. Recovery ratio of normal ovarian function in test group and control group was 75% and 50% (P =0.013) respectively, and the median menstrual recovery time in two groups was 4.65 months and 6.65 months (P = 0.046) respectively. Statistically significant differences were found between two groups. Conclusion Goserelin can effectively protect ovarian function during chemotherapy , increase the ratio of normal ovarian function, shorten menstrual recovery time, and shows good tolerance.

Objective To learn the species distrilbution and drug-resistance of Gram-negative bacilli among bloodstream infections (BSI) in Yunnan province of China during 2012 to 2014.Methods Bloodstream infected Gram-negative bacilli were collected from 28 general hospitals in Yunan province of China.Data from all hospitals were applied with the same method of bacteria culture,isolation,identification and antibiotic sensitivity tests.WHONET 5.6 was used to perform the statistical analysis.Results A total of 9042 clinical strains of non-repetitive gram-negative bacilli were collected.Enterobacteriaceae and Non-fermenter bacteria accounted for 82.4％ and 17.6％ respectively.Enterobacteriaceae were mainly composed of Escherichia coli and Klebsiella pneumoniae.Non-fermenter bacteria were mainly composed of Acinetobacter baumannii and Pseudomonas aerouginosa.Escherichia coli accounted for the majority 49.29％,other species were Klebsiella pneumoniae 13.17％,Acinetobacter baumannii 4.04％ and Pseudomonas aeroginosa 3.85％.The susceptible rate of Enterobacteriaceae strains to the first generation cephalosporin was lower than 60％.The susceptible rate of E coli and Klebsiella pneumoniae to impenem was close to 100％,to Amikacin was more than 85％,to piperacillin-tazobactam was more than 70％,to Cefepime was more than 70％.But the susceptible rate of Klebsiella pneumoniae to impnem and amikacin decreased year by year from 2012 to 2014.The susceptible rate of Enterobacter cloacae to Amikacin was 86.4％ ～ 93.6％,Ciprofloxacin 70.5 ～ 76％,Cefepime 72.1 ～ 82.8％.It was less than other Enterobacteriaceae.The susceptible rate of Non-fermenter bacteria to normal antibiotics was much lower than Enterobacteriaceae.The susceptible rates of Pseudomonas aeroginosa to Impnem was 58.9％,Tobramycin 85％,Ciprofloxacin 71.7％,Amikacin 82.9％,Piperacillintazobactam 75.3％,Piperacillin59.6％,Atreonam 46.5％,Ceftazidime 69.1％ and Cefepime 68.9％ respectively.Furthermore,Acinetobacter baumannii's durg-resistance was more severe.The susceptible rate of Acinetobacter baumannii was lower than 30％,to the third and fourth generation cephalosporin,the susceptible rate of Ampicillin/Sulbactam,Cefoperazone/Sulbactam,Carbapenems,Piperacillin/Tazuobatan,Quinolones and Carbapenems was less than 40％.Conclusion Gram-negative bacilli have low susceptibilities among BSI.E.coli is the most common pathegon among BSI.The resistant rate of Non-fermenter bacteria to normal antibiotics is severe in hospitals.

Objective To explore the CT manifestations of non-functional islet cell tumor(NFICT)Methods The findings of plain and enhancement CT scanning from 17 cases with NFICT,which were confirmed by the surgeries and pathological sections,were analyzed retrospectively.Ninty ml of non-ioniodine contrast reagent with 3ml/s injection flow rate was employed as the enhancer for measuring the arteriovenous double phase CT value of the pancreas and tumor.Results Tumors were found in all the cases who received CT scan.Compared with pancreatic substance in the CT plain scan,tumors with low density were found in 2 cases,tumors with mixed low density in 11 cases and tumors with isodensity in 4 cases.Local calcification in tumor was found in 5 cases.Various degrees of strengthening were showed in 17 cases with enhancement scanning.Obvious enhancement in arterial phase presented in 5 cases,moderate enhancement in 6 cases and slight enhancement in 6 cases.Conclusions CT plain scan of NFICT shows that the tumor margins are clear and some tumors have calcification.All tumors in the CT enhancement scanning show various degrees of enhancement,the persistent enhancement from arterial phase to portal vein phase is the characteristic manifestation of NFICT.

Objective To compare the clinical effects and adverse effects of microwave ablation (MWA) with sorafenib and sorafenib monotherapy in the treatment of advanced-stage hepatocellular carcinoma (HCC).Methods Medical records and follow-up information of 57 patients with advanced-stage HCC were retrospectively reviewed.25 patients were treated with MWA combined with sorafenib (combined group),and 32 patients were treated with sorafenib monotherapy (monotherapy group).The end points were therapeutic effect,progression-free survival (PFS),overall survival (OS) and adverse reactions.Results The objective response rate in the combined group was similar to the monotherapy group (16.0％ vs.3.1％,x2 =1.521,P =0.217).The disease control rate in the combined group was significantly higher than that in the monotherapy group (80.0％ vs.50.0％,χ2 =5.429,P =0.020).The median PFS in the combined group was longer than that in the monotherapy group (6.0 months vs.3.2 months,x2 =7.675,P =0.006),but the median OS was similar (11.5 months vs.8.5 months,x2 =2.480,P =0.115).The serious adverse reactions were similar between the two treatment groups (44.0％ vs.34.4％,x2 =0.549,P =0.459).Conclusion MWA plus sorafenib is superior to sorafenib alone with respect to PFS in patients with advanced-stage HCC,although it may not improve OS,with no increased risk of serious adverse reactions.

ObjectiveTo explore the efficacy and toxicity of nimotuzumab plus chemotherapy in the treatment of metastatic gastrointestinal tumor.MethodsObservationgroup 22 patients with metastatic gastrointestinal tumor with confirmed diagnosis,were treated with nimotuzumab in combination chemotherapy.Nimotuzumab was given 200 mg weekly for at least six weeks. Control group 21 patients with metastatic gastrointestinal tumor with confirmed diagnosis were treated with only chemotherapy.ResultsThe effects of observation group could be observed in 22 patients, the rate of response(RR)was 31.8％ (7/22), and the disease control rate (DCR) was 72.7 ％ (16/22).QOL was improved.The effects of observation group could be observed in 21 patients,RR was 14.3 ％ (3/21),and the disease control rate was 42.8 ％ (19/21).DCR and QOL improvements were statistically significant different between the two groups.(x2=3.939,x2=4.250,P＜0.05).The two groups had no significant difference in RR and toxicity.ConclusionNimotuzumab in combination with chemotherapy is effective and can improve the disease control rate, toxicity, tolerance,quality of life.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.
