Objective To evaluate the efficacy and safety of trimebutine combined with mosapride on functional dyspepsia. Methods Patients with functional dyspepsia were randomly divided into three clinical groups. Group A (n=116) received 0.2 g trimebutine after meal,group the drug combination B (n=116) received 5 mg mosapride before meal,and the drug combination group (n=115) received 0. 2 g trimebutine after meal plus 5 mg mosapride before meal. All medications were taken orally three times daily for 4 weeks. Improvement in clinical symptoms and adverse reactions in each group were evaluated at the end of study. Results A total of 339 patients among 347 enrollees completed the treatment and follow-up. The clinical efficacy on postprandial fullness, early satiation, epigastric pain, epigastric burning, upper abdominal bloating and nausea were 88. 4%,76. 9%,72. 9%,61. 8%,86. 7% and 81. 7%,respectively in the drug combination group after 4-week treatment,which were superior to those in group A or B (P<0. 05) except for epigastric burning. The total effective rate of the drug combination group was 78. 8%,significantly higher than the other two groups (P<0. 05). The total incidence of side effects in the drug combination group was 1. 8%,similar to that of group A and B (1. 8% and 0. 9%,respectively, P =0. 776). Conclusion Trimebutine combined with mosapride is safe and effective for improving symptoms in functional dyspepsia.

Objective To investigate the expression of long chain non-coding(lnc) RNA LOC285194 in breast cancer tissue and paracancerous tissue and its clinical significance.Methods Forty-two samples of paraffin embedded breast cancer tissue and 16 samples of paraffin embedded paracancerous tissue were selected.The expression of lncRNA LOC285194 in these tissue were detected by using quantitative real-time polymerase chain reaction(PCR).Then its correlation with clinicopathological features was analyzed.Results The expression level of lncRNA LOC285194 in breast cancer tissue was significantly lower that in the paracancerous tissue (P＜0.01);the level of lncRNA LOC285194 in human epidermal growth factor receptor-2(HER2)overexpression tissues was up-regulated compared with HER2 negative breast cancer tissue(P =0.013),there was a positive correlation between them(r=0.385,P=0.012).Conclusion lncRNA LOC285194 may play the role of cancer suppressor gene and may be involved in the generation of breast cancer by HER2 association,which may become a target gene of breast cancer treatment.

Objective To analyze the blood screening results after adjustment of critical value 40 to 50 U/L and to observe the effect of reducing blood scrap rate and to discuss the correlation between ALT and HBV,HCV infection.Methods We screened 2656 blood donors (ALT >40 U/L)by serological and nucleic acid amplification testing(NAT)in Qingdao blood center from 2013 to 2014,and conducted the correlation analysis by chi square test.Results 1 771 cases (66.68%)were ALT 40-50 U/L,including 6 cases of HBsAg ELISA (+),2 cases NAT (+),4 cases NAT(-).In the 8 cases of anti-HCV ELISA (+)samples,4 cases NAT (+),3 cases NAT (-),1 case with positive TP without NAT result.In 885 blood donors with ALT>50 U/L,5 cases were HBsAg-reactive,7 cases were anti-HCV-reactive,and 873 cases were negative.Related statistics showed that there was no signifi-cant difference between ALT and HBV infection (P <0.05),but significant difference was found between ALT and HCV infection (P >0.05).Conclusion The proportion of blood donors with ALT 40-50 U/L is much higher than that with ALT >50 U/L do-nors.Adjustment of the critical value greatly reduces blood scrap rate.Elevated ALT is associated with the infection of HBV but not with HCV.

Objective To investigate the association of urinary albumin-to-creatinine ratio (UACR) and the diameter of retinal vessel in population with essential hypertension in Fujian coastal area.Methods Central retinal artery and vein equivalents (CRAE and CRVE) were measured from the avoiding mydriatic digitized photographs and semi-automatic fundus analysis software,as well as albumin and urine creatinine.Results There were significant differences in CRAE levels among the normal control group,normoalbuminuria with essential hypertension group and microalbuminuria with essential hypertension group [(135.68 ± 10.10) μm,(129.79 ± 10.48) μm,(125.29 ± 11.17) μm,all P values ＜0.01].The CRAE levels were significantly negative correlated with UACR (r =-0.29,P ＜ 0.01).Linear regression analysis showed CRAE was associated with UACR in the patients with hypertension(β =-5.0,P ＜ 0.01).Logistic regression analysis showed,systolic blood pressure (β =1.08,P =0.02) was risk factor for CRAE abnormality.The CRAE abnormality was increased in turn in the normal control group,normoalbuminuria with the essential hypertension group and microalbuminuria with essential hypertension group (P ＜ 0.01).Conclusion The reduction of central retinal artery diameter are associated with the hypertensive renal damage.UACR and CRAE could be used to evaluate the microvascular lesions and be used as an indicator to assess the target organs damage in essential hypertension patients.

Objective:To observe the changes of skeletal muscle indexes in elderly patients with type 2 diabetes complicated with sarcopenia treated with sitagliptin and acarbose.Methods:A total of 60 patients over 60 years old with type 2 diabetes complicated with sarcopenia in Dalian Municipal Central Hospital from January 2019 to January 2020 were selected and divided into two groups by random number table method.One group received sitagliptin and metformin,and the other group received acarbose and metformin. The changes of skeletal muscle indexes, glucagon-like peptides-1 (GLP-1), insulin resistance index (HOMA-IR) and inflammatory indexes were compared between the two groups at baseline and 36 weeks after treatment.Results:After treatment, the skeletal muscle index (SMI) of sitagliptin group was increased (5.94 ± 1.52 vs. 5.99 ± 1.52), and the difference was statistically significant ( P<0.05). Muscle strength and SMI decreased in acarbosse group (18.75 ± 4.64 vs. 17.72 ± 4.44, 6.09 ± 1.74 vs. 6.00 ± 1.71), with statistical significance ( P<0.05). GLP-1 increased in sitagliptin group, 0 min: (10.65 ± 1.68) pmol/L vs. (12.41 ± 1.88) pmol/L; 60 min: (22.79 ± 2.85) pmol/L vs. (25.51 ± 2.79) pmol/L; 120 min: (24.26 ± 2.94) pmol/L vs. (29.49 ± 2.91) pmol/L; 180 min: (11.68 ± 1.84) pmol/L vs. (12.88 ± 1.83) pmol/L. There were significant differences ( P<0.05). HOMA-IR and CRP decreased: 4.73 ± 3.04 vs. 3.16 ± 2.41, (2.39 ± 0.50) mg/L vs. (2.33 ± 0.43) mg/L, and the differences were statistically significant ( P<0.05). HOMA-IR in acarbose group decreased after treatment (5.80 ± 3.94 vs. 4.00 ± 1.63), and the difference was statistically significant ( P<0.05). Comparison between the two groups after treatment, the decreased value of muscle strength in sitagliptin group was less than that in acarbose group, and the difference was statistically significant ( P<0.05). GLP-1 and overall GLP-1 area under the curve in sitagliptin group were higher than those in acarbose group (67.64 ± 6.81 vs. 58.98 ± 6.72), with statistical significance ( P<0.05). HOMA-IR and CRP in sitagliptin group were lower than those in acarborose group: 3.16 ± 2.42 vs. 4.00 ± 1.63, (2.33 ± 0.43) mg/L vs. (2.41 ± 0.70) mg/L, with statistical significances ( P<0.05). Conclusions:Sitagliptin therapy improves muscle mass and protects muscle strength in elderly patients with type 2 diabetes mellitus and sarcopenia.

【Objective】 To compare the detection performance of Cobas s201, a minipool(MP) nucleic acid test(NAT) system, and Panther, a individual donation(ID) NAT system, in blood donor screening. 【Methods】 NAT was conducted on 126 359 blood samples, and initially reactive (IR) samples were either discriminated or resolved by ID testing.The non-discriminated reactive (NDR) samples implicated in Panther sysytem were subjected to ID-NAT by Cobas s201. Some non-repeatable reactivet(NRR) and repeatable reactive (RR) samples implicated in Cobas s201 system were subjected to ID-NAT by Panther. 【Results】 61 MP-IR cases were implicated in a total of 85 128 samples that detected by Cobas 201, and 29(0.34‰) were RR after resolved by ID testing. 74(1.79‰)IR samples were implicated in 41 231 samples that detected by Panther, and 22 (29.73%) were DR-HBV after discriminatory test. Among the NDR 28 samples detected by Panther multiplex system, 7 were positive by Cobas s201 single sample (PP1) whereas non-reactive in simulated MPs of six by Cobas 201.In 28 RR samples resolved by Cobas 201, 24 positive and 4 negative samples were retested by Panther. Among the 11 samples presenting inconsistent retest results by Panther and Cobas 201, 10 were anti-HBc positive, carrying low viral load HBV. 【Conclusion】 The NAT-yield by Panther was significantly higher than that by Cobas s201. Some samples with negative discriminatory results were OBI, and it is necessary to further track and verify the unidentified samples. Cobas s201 is more suitable for a wide array of MP-NAT testing while Panther sample loading, which is flexible and easy to operate, is more suitable for ID-NAT with medium sample size.

【Objective】 To study and analyze the serological and viral charactereristics of hepatitis B virus(HBV) infection in voluntary blood donors in Qingdao. 【Methods】 315 520 blood samples of voluntary blood donors were screened by ELISA combined with nucleic acid testing (NAT). All HBsAg-/HBV DNA+ samples were subjected to high-precision viral load detection and five serological markers of HBV. The sequence of HBV S gene was detected by PCR direct sequencing, and virus genotypes and amino acid mutations were analyzed. 【Results】 A total of 604(0.20%)HBV ELISA or NAT reactive samples were detected: HBsAg+ /HBV DNA- in 307(0.10%) cases, HBsAg-/HBV DNA+ in 138(0.04%) and HBsAg+ /HBV DNA+ in 157(0.05%). Among the 138 HBsAg-/HBV DNA+ donors, 118(85.5%) carried anti-HBc, and 45 (32.61%) carried sole anti-HBc and 5 (3.62%) carried both HBsAg and anti-HBc. In viral load detection, 64 were quantitatively negative and 74 were quantitatively positive, of which 42 were HBV DNA <20 IU/mL and 32 > 20 IU/mL. 13 HBsAg-/HBV DNA+ samples were successfully amplified and sequenced, and 5 were genotype B, presenting a total of 17 amino acid mutations without any deletion or insertion, and 8 were genotype C, presenting a total of 41 amino acid mutations and 2 amino acid deletions. 【Conclusion】 NAT, in combination of ELISA, provides additional safety in detecting potentially infectious HBV during the window period and occult HBV infection (OBI). The viral load was low in OBI infected donors, and anti-HBc+ was the main manifestation.The dominating HBV genotypes are genotype B and C, suggesting HBsAg amino acid mutations may be related to the formation of OBI.
