Objective To explore the efficacy and safety of Linagliptin in combination with Metformin in newly diagnosed T2DM patients. Methods A total of 140 newly diagnosed T2DM patients were enrolled in this study. All the patients were admitted in the Endocrinology and Metabolism department of our hospital from January 2013 to October 2013. Random number table method was used in patients’ selection. All the patients were divided into two groups :Linagliptin plus Metformin group (Linagliptin group ,n=70) and Glipizide plus Metformin group (Glipizide group ,n=70) ,and followed up for 12 weeks. Efficacy and safety of treatment were compared between the two groups. Results The difference of FPG ,2 hPG and HbA1 c did not reach the statistical significance between the two groups at baseline treatment (P>0.05). FPG ,2 hPG and HbA1 c were significantly lower after treatment compared with baseline in both groups (P<0.05). FC-P ,2 hC-P ,HOMA-β,HOMA-IR ,IAI and adiponectin level at baseline were similar between the two groups ( P> 0.05 ). All these indicators were improved after treatment in both groups (P< 0.05) ,and were significant better in Linagliptin group than in Glipizide group. Adverse events rate were significantly higher in Glipizide group than in Linagliptin group (18.57%vs 5.71% ,χ2 = 5.423 ,P= 0.020 ). Conclusion The efficacy of Linagliptin in combination with Metformin in newly diagnosed T2DM patients was similar with Glipizide plus Metformin. The β cell function improvement was better and APN level was higher after Linagliptin treatment.

The most frequently observed structures were round, white-yellow, amorphous structures (40.53%) , followed by four-leaf clover-like pattern (33.48%) , polylobular pattern (20.26%) and nonspecific pattern (5.73%) . Conclusion:Orifices, vascular structures and white-yellow amorphous structures can be observed in molluscum contagiosum by dermoscopy, and the most common vascular pattern is the crown-shaped vessel.

Objective To observe the clinical effects of laparoscopic varicocelectomy to ejaculum quality in patients with varicocele.Methods Fifty patients with varicocele were treated by laparoscopic varicocelectomy.The patients were grouped into Group A and Group B according to venous diameter.Semen parameters including semen volume,sperm density,sperm motilities (a + b + c),sperm motilities (a + b),sperm motilities (a),total sperms,normal spermmorphology rate and sperm survival rate were measured and recorded before operation and 1,3,6 months after operation.Results After the follow-up of 6 months above in 50 cases,there is no significant difference about semen volume preoperative and postoperative at different follow-up time(P ＞ 0.05).In some semen parameters(sperm density,sperm motilities,total sperms,normal spermmorphology rate),there is no significant difference between preoperative and postoperative 1 month(P ＞ 0.05),but there is significant difference between postoperative 3 months and postoperative 6 months(P ＜ 0.05).There is no significant difference in preoperative semen parameters between the 2 groups(P ＞ 0.05),but there is significant difference in postoperative 6 month(P ＜0.05).In Group A,there is significant difference in sperm density between preoperative and postoperative 1 month (P ＜0.05).In Group B,there is significant difference in sperm density,sperm motilities and normal spermmorphology rate between preoperative and postoperative 1 month(P ＜ 0.05).Conclusions Laparoscopic varicocelectomy has a positive effect on sperm parameters,it can significantly improve postoperative semen parameters.Semen parameters improve to a relatively stable level by 3 months following operation.

Objective: To investigate the trends in mortality and life lost due to female breast cancer among in Suzhou City from 2007 to 2021, so as to provide insights into improvements of breast cancer control strategy in Suzhou City. Methods: The epidemiological and clinical data pertaining to dead female breast cancer cases in Suzhou City from 2007 to 2021 were collected from Suzhou Municipal Chronic Disease Surveillance System, including gender, age and cause of death. The crude mortality, standardized mortality, years of potential life lost (YPLL), years of potential life lost rate (YPLLR), standardized YPLL (SYPLL), standardized YPLLR (SYPLLR) and average years of life lost (AYLL) due to female breast cancer were calculated. All data were standardized by the Fifth National Population Census in 2000, and the trends in mortality of breast cancer were estimated using average annual percent change (AAPC). Results: Totally 4 425 death occurred due to female breast cancer in Suzhou City from 2007 to 2021, with a crude mortality rate of 8.67/105, which appeared a tendency towards a rise (AAPC=1.83%, t=5.080, P=0.001), and the standardized mortality was 4.68/105, which appeared no significant changes (AAPC=0.13%, t=0.356, P=0.727). The crude mortality rates of female breast cancer were 0.62/105, 10.33/105 and 21.69/105 among women at ages of 15 to 34, 35 to 64 years and 65 years and older, respectively, which appeared a tendency towards a rise (χ2trend=2 315.683, P=0.001). The crude mortality of female breast cancer was 8.66/105 in urban areas and 8.86/105 in rural areas, both appearing a tendency towards a rise (urban areas: AAPC=1.73%, t=3.290, P=0.006; rural areas: AAPC=2.68%, t=6.565, P=0.001). The YPLL, SYPLL, YPLLR, SYPLLR and AYLL of female breast cancer were 44 485 person-years, 30 387 person-years, 0.99‰, 0.68‰ and 14.94 years per person, and both YPLLR (AAPC=-1.06%, t=-2.193, P=0.047) and AYLL (AAPC=-1.53%, t=-4.783, P=0.001) appeared a tendency towards a reduction, respectively. Conclusion The crude mortality of female breast cancer appeared a tendency towards a rise and the life loss appeared a tendency towards a decline in Suzhou City from 2007 to 2021. The elderly population should be given a high priority for breast cancer control.

Objective To investigate the invasion,internalization and the organelles damage of the cultured dendritic cells ( DC2.4 strain) during Vibrio vulnificus (Vv) infection.Methods The study model was the cultured DCs infected by Vv 1.1758 strain.Electron microscopy was used to observe the localization of bacteria in different time point of infection,cell morphology and the process of organelles changes.The cytoskeleton structure including the microfilaments and the microtubules rearrangement was examined by the fluorescence microscope.Results The Vv were pinocytosed into the DC cells through double-sides,and localized at 1-2 μm of the inner side membrane.It cost 1.27,1.87,3.43 hours reaching the infection ratio of 25％,50％,75％,respectively.Using electron microscopy,the DCs had been observed the phagosome formation within 1h,chromatin activation within 2 h,chromatin aggregation 4 h,and the significant cytoskeleton structure disruption within 6 h.Endoplasmic reticulum,mitochondria and lysosomes became swollen.In DCs,the protruding filaments gradually reduced,and their shape changed from the point-like to the linearlike aggregation at the inner side of the plasma membrane,extended microtubules disappeared,the microtubules at the outside nuclear membrane striking rearranged.Conclusion After DC was infected by Vv,the bacteria were pinocytosed into the inner side of DC membrane,and the microfilaments were observed to move from the cytoplasm to cell membrane.In addition,the microtubules moved from the synapse and the cell membrane to the nuclear membrane.The high lethality of Vv could provoke to the DCs cytoskeleton rearrangements.

Objective To investigate the Relationship between the CYP2C19 polymorphism and the efficacy of triple therapy with lansoprazole on Helicobacter pylori infection. Methods 125 elderly patients diagnosed with H.pylori infection were treated with triple therapy. Polymorphism of CYP2C19 was measured by AS-PCR. 105 young patients were selected as control group. The relationship between the polymorphism and eradication rate were analyzed. Results Among the 125 patients,eradication rate of extensive metabolizer group,internal metabolizer group and poor metabolizer groups was 85.29%,76%and 89.39%, respectively. There was no significant difference between groups (P > 0.05). Eradication rate showed no difference between experimental and control group either (P>0.05)(P>0.05). Conclusion The results suggests that the CYP2C19 polymorphism has no correlation with the eradication rate of Helicobacter pylori infection by triple therapy with lansoprazole in elderly patients.
