Objective To explore the clinical effect and adverse effects of tiggio combined with oxaliplatin on the treatment of advanced gastric cancer. Methods From January 2014 to January 2017, 88 cases with advanced gastric cancer were selected as the samples in Yangling demonstration zone hospital. All the patients were randomly divided into the control group (n = 44) and the observation group (n = 44). The control group and the observation group were treated with tiggio and tiggio combined with oxaliplatin respectively, and the clinical effect and the occurrence of adverse reactions in the two groups was compared. Results The total effect in the observation group was 91.0％, which was significantly higher than that in the control group (75.0％), (P<0.05); The incidence of adverse reactions in the control group was 27.3％, while in the observation group was 9.1％ the difference was statistically significant(P<0.05). Conclusion Tiggio combined with oxaliplatin in the treatment of advanced gastric cancer, the clinical effect is significant, the incidence of adverse reactions is low, high security, worthy of promotion.

Objective To investigate the role of interferon ?on smooth muscle cells proliferation and migration after balloon injury. Methods Animal model of rabbit iliac artery balloon injury was set up, smooth muscle cells derived from injured artery were cultured. Smooth muscle cells were divided into four groups ( control, TGF ? 1, IFN ?, TGF ? 1 and IFN ?).Cells from each group were treated with medium or TGF ? 1 (10 ng/ml) and/or IFN ?(500 u/ml) for 72 h separately. Smooth muscle cell proliferation was determined by cell count and MTT, migration of smooth muscle cells was also detected. Matrix metalloproteinase 2 was also detected by zymography. Results Our results showed that, compared with group control(2.875?0.323?10 5 cells/ml,279.9?8.129 ?m), TGF ? 1 increased cell count (4.188?0.239?10 5 cells/ml, P

Objective To explore the role of serotonin(5-HT) in obsessive compulsive disorder(OCD) and the difference in platelet 5-HT content between OCD and healthy controls, the obsession and the compulsion subgroup. Methods The concentration of serotonin (5-HT) in twenty-seven patients with OCD and twenty-seven patients without OCD were detected in the study. Results Platelet serotonin level in patients with OCD ( ( 139 ±172 ) μg/L) was lower than that in patients without OCD ( ( 248 ± 215 ) μg/L), and the differences were significant (P＜0.05). Conclusion The present results support the hypothesis that 5-HT hypofunctionality contribute to OCD. And the differences between the obsession and the compulsion subgroup in the role of 5-HT are significant.

AIM: To study pattern recognition of the fingerprint of Polygonum orientale from Guizhou Province. METHODS: 20 batches of samples,Polygonum orientale,come from different producing areas and harvest time were carried out to gain fingerprints by HPLC-DAD,as compared with retention time and ultraviolet spectra of standard substances.The pattern recognition of the characteristic fingerprint of Polygonum orientale,known as cluster analysis and principal component analysis,formed. RESULTS: The fingerprint of 20 batches of Polygonum orientale showed 12 characteristic peaks,in which 9 common peaks were confirmed.the samples were grouped into 3 types of harvest time. CONCLUSION: The quality of Polygonum orientale in Guizhou Province is stable,the pattern recognition of the fingerprint provides the experimental basis for manufacture and quality control of Polygonum orientale.

To study on the phylogenetic characterization of the VP1 genes of coxsackievirus A16 (CVA16) causing hand-food-mouth disease (HFMD) isolated from Anhui province in 2014. A total of 413 throat swab specimens from HFMD patients were collected during January to November, 2014 for the isolation and identification of enteroviruses using real-time RT-PCR assays. The VP1 regions of CVA16 isolates were amplified using RT-PCR and sequenced. And the phylogenetic tree was constructed among the VP1 regions of those isolates, the different genotypes and sub-genotypes of CVA16 strains. A total of 97 enteroviruses were isolated from 413 samples, the positive rate was 23.49% (97/413), including seventeen CVA16, seventy six HEV71 and four other enteroviruses. The results of the phylogenetic tree showed that 17.CVA16 strains isolated from Anhui in 2014 clustered within B1b evolution branch of B1 genotype. The nucleotide and amino acid sequence identities were 95.30%-100% and 98.70%-100% among the isolates, respectively, but within B1b branch of 17 strains formed several small transmission chains. The nucleotide acid of 17 CVA16 isolates in Anhui province were closed to the strains isolated from Yunnan, Hunan, Guangdong, Tibet and Jiangsu, especially from Hunan in 2013 and from Shenzhen of Guangdong in 2014, the identity were 96.40%-99.70%. The CVA16 strains isolated from Anhui in 2014 were all belong to genetic subtype B1b of B1 genotype was dominant, and among those isolates, several small virus transmission chains had formed with co-circulating and evolution.

Objective Through comparing ultrasound-guided microwave ablation (MWA) with surgical resection for the treatment of nodular goiter to evaluate the effect of RFA on the thyroid function.Methods A total of 50 patients with nodular goiter,who were admitted to authors' hospital during the period from January 2010 to January 2013 to receive ultrasound-guided MWA,were selected and used as the study group;and other 96 patients with nodular goiter,who were encountered at authors' hospital during the same period to receive partial thyroidectomy,were collected and used as the control group.Of the 50 patients in the study group,RFA of unilateral lobe nodules was performed in 8 and RFA of bilateral lobe nodules in 42.Among the 96 patients in the control group,unilateral lobe nodules were seen in 52 and bilateral lobe nodules in 44.Postoperative complications were recorded,the serum FT3,FT4,TSH levels were determined at one week,as well as one,3,6 and 12 months after the treatment.The results were statistically analyzed.Results All patients were followed up for 12 months.In the study group,no complications occurred;one week after RFA the serum FT3 and FT4 levels increased while the serum TSH level decreased when compared with preoperative ones,and the differences were statistically significant (P＜0.05).In the control group,bleeding asphyxia occurred in one patient,hoarseness in 5 patients and hypocalcemia convulsion in 3 patients.One week after partial thyroidectomy,the serum FT3 and FT4 levels increased while the serum TSH level decreased when compared with preoperative data,and the differences were statistically significant (P＜0.05).One week after surgery thyroxine replacement therapy was routinely given to 44 patients who had received bilateral subtotal thyroidectomy.Three patients who had received unilateral subtotal thyroidectomy developed hypothyroidism at 3,6 and 8 months after the surgery respectively.In other 49 patients receiving unilateral subtotal thyroidectomy the serum FT3,FT4,TSH levels determined at one,3,6 and 12 months after surgery were significantly different from those in the patients of the study group (P＜0.05).Conclusion For the treatment of nodular goiter,ultrasound-guided MWA is quite safe.MWA has very slight effect on thyroid function and is definitely superior to subtotal thyroidectomy.Therefore,MWA is a minimally invasive technique which is worthy of clinical promotion.
