Objective Clinicians are very cautious on operationsof laparoscopic cholecystectomy(LC) in patients with cirrhosis because of its high risk.And few researches were carried out on this situation.This article aimed to summarize the LC in cirrhotic patients with cholecystolithiasis and cholecystitis, observe the clinical therapeutic effect and analyze the feasibility of this treatment.Methods The clinical data of 112 operation cases of cholecystolithiasis and cholecystitiswith cirrhosis were retrospectively analyzed from January 2012 to December 2015 in Department of General Surgery, Changzhou Third People's Hospital.According to different surgical methods, all patients were divided into laparoscopic cholecystectomy group (n=56) and open cholecystectomy group (n=56).Peroperative period indicators including operation time, intraoperative blood loss, Postoperative exhaust time, postoperative hospital stay and complications were recorded, data were analyzed to evaluate the clinical effect.Results Compared with open cholecystectomy group, laparoscopic cholecystectomy group had shorter operative time[(54.28±15.34)min vs (91.63±20.09)min,P=0.000];less intraoperative blood loss[(73.42±4.28)mL vs (98.54±7.16)mL,P=0.000], shorter Postoperative exhaust time and postoperative hospital stay(P=0.000).The complication incidence in laparoscopic cholecystectomy group were lower than that in open cholecystectomy group(7.14% vs 21.43%, P<0.05).Conclusion Operation of laparoscopic cholecystectomy on cirrhotic patients has a high clinical efficacy.It is safe and feasible to carry out such an operation on the basis of strict indication and reasonable risk assessment.

Objective To analyze the outcomes of renal transplantation from donation after citizen death (DCD) in our single center.Method We retrospectively investigated the recipient outcomes of renal allografts from DCD.Between November 2010 and 31st December 2014,our institution performed 242 renal transplants from DCD.Outcome variables (survival of recipients/allografts and adverse events) and characteristics of marginal donor transplants were analyzed.Result There were 139 males and 44 females in the enrolled 183 donors,and the range of age was from 2 days to 68 years.183 donors included 102 cases of donation after brain death (category Ⅰ),22 cases of donation after circulatory death (category Ⅱ) and 59 cases of donation after brain death followed by circulatory death (category Ⅲ).Utilizing these renal allografts,we performed 242 kidney transplantations including 237 single kidney transplants and 5 pediatric en bloc kidney transplants.The age of recipients ranged from 12 to 64 years.The data indicated that the 1-year recipient/allograft survival rate was 93.8％ and 90.5％,respectively.The rate of delayed graft function (DGF) was 33.1 ％,higher than that from executed prisoners allografts (23.6％,P＜0.05).However,the rate of 1-year acute rejection,interstitial pneumonia and the other adverse events (urinary fistula,ureteral obstruction and cardiac and cerebral vascular accident,etc.) was similar to that from executed prisoners allografts.In addition,good results from pediatric and elder donor renal transplantation were shown in our data,even though the discard rate of elder donor kidney was high.Conclusion By comprehensive evaluation,strictly screening donors and enhancing the rnanagenent of donors,the long-term survival of recipients may be prolonged and the incidence of DGF and primary graft non-function (PNF) may be decreased.The marginal donors from pediatric and elder DCD donors could be utilized in clinical transplantation safely and effectively as long as reasonable evaluation was carried out.

Objective:To analyze the clinical characteristics of primary acute myeloid leukemia (AML) (non-M3 type) in children suffering from different levels of platelet count(PLT).Methods:In the Tumor Hospital of Zhengzhou University from January 2014 to December 2018, laboratory and clinical data of 247 de novo primary AML pediatric patients were retrospectively reviewed.According to the PLT before treatment, patients were divided into very low platelet group (VLG), low platelet group (LG) and non-lowing platelet group (NLG), with<50×10 9/L, ≥50×10 9/L but <125×10 9/L and ≥125×10 9/L as the boundaries.All patients were followed up until June 30, 2019.Meanwhile, the follow-up data was obtained by consulting medical records or by telephone.SPSS 17.0 software was applied for data analysis. Results:In general clinical features, a different group of hemoglobin (Hb) content, fusion gene AML- ETO and clinical risk stratification were statistically significant in different PLT groups ( χ2=11.270, 12.115 and 12.848, respectively, all P<0.05). However, the differences of other indicators in different groups of PLT were not statistically significant (all P>0.05). There were no statistically significant differences in terms of 3-year disease-free survival(DFS) rate (59.3%, 36.3%, 50.4%) among the 3 groups (all P>0.05). The median total survival(OS)time(40.5 months)and 3-year OS rate(41.0%) of NLG patients were significantly higher than those of VLG(23.1 months, 30.1%)and LG(14.1 months, 18.2%)patients, with statistically significant differences( χ2=7.798 and 6.553, respectively, all P<0.05). The univariate analysis of gender, white blood cell(WBC), Hb, PLT, lactic dehydrogenase(LDH), FLT3-ITD, NPM1, DNMT3A, CEPBA, C-KIT, AML-ETO, molecular genetic prognosis, complete remission(CR), and hemopoietic stem cell transplantation(HSCT) displayed that DNMT3A mutation was an adverse factor that affects patients′ OS ( χ2 =5.834, P<0.05), and the positive factors that influences OS were non-reducing PLT before treatment, and obtaining CR and subsequent HSCT ( χ2=7.798, 79.168, and 31.337, respectively, all P<0.05). Multi-factor analysis revealed that the independent protective factors that affect patients′ OS were the non-reducing PLT before treatment, and obtaining CR and subsequent HSCT( Wald=42.760, 15.918, and 10.183, respectively, all P<0.05). Conclusions:Before treatment, non-reducing PLT is a protective factor for primary childhood AML patients, and the prognosis is satisfying.

Experiment teaching is a most important item of college teaching, and plays a vital and unexchangeable role to train students for their ability to practice and to innovate. To construct a feasible and scientific examination system of experiment teaching, will significantly help deepen the reformation of experiment teaching and improve the teaching quality. So according to the request for cultivating qualified ap- plication person, we preliminarily constitute the valuation system throughout the whole course and in the final, of theoretic examination and practice examination, and combined with students’ self-valuation and valuation from teachers. In fact, the system works well with a perfect effect.

Objective To observe Meissner's corpuscles in prepuces of different shapes and ages. Methods The Meissner's corpuscles were detected with immunohistochemical stain in 204 prepuce sam- ples of different shapes and ages (3-59 years),and the density of Meissner's corpuscles in every sample was obtained as well.The difference of Meissner's corpuscle densities between phimosis and redundant pre- puce,and correlation between Meissner's corpuscle densities and ages were analyzed with Chi-square test and linear regression,respectively.Results The density of Meissner's corpuscles in redundant prepuce has begun to increase since infancy and reached the peak at the age about 15 years.No significant difference in densities of Meissner's corpuscles between phimosis and redundant prepuce was observed till the age of 20 years,and then there was a trend of disappearance of Meissner's corpuscles in redundant prepuce.A signifi- cantly negative correlation between the densities of Meissner's corpuscles and ages was revealed in redundant prepuce (r=-0.236,P=0.009),whereas an insignificantly positive correlation between the densities of Meissner's corpuscles and ages was shown in phimosis (r=0.193,P=0.084).Conclusions The den- sities of Meissner's corpuscles in redundant prepuce develop synchronically with genital differentiation and accord with the status of sexual function in adult males.The persistent high level of Meissner's corpuscles in adult phimosis might be a mechanism of physiological compensation.

Objective To observe the rate-adaptive response of dual sensor pacemakers integrated with activity sensor and minute ventilation sensor.Methods Fifty patients with chronotrepic incompetence were implanted with pacemakers of integrated sensor.The patients with pacemakers implanted were arranged to take upstairs test,downstairs test and tapping test under the monitor of integrated sensor,minute ventilation sensor and activity sensor respectirely.The rate-adaptive responses were tracked down every 15 seconds with remote heart rate monitor.The results were compared with the control group patients with normal sinal chronotropic function(n=15).Results In activity sensor group,pacing rates were significantly higher than the normal control group in downstairs test and tapping test.In minute ventilation sensor group,pacing rates increasement was significantly slower in the beginning of upstairs test.Pacing rates of integrated group were similar to the normal control group in upstairs and downstairs tests.Conclusion The rate-adaptive pacing response of dual sensor integrated with activity sensor and minute ventilation sensor,which is mostly close to the normal chronotropic response,better than that of single sensor.
