Objective To investigate the risk factors for pancreatic fistula after duct-to-mucosa pancreaticojejuuostomy (PD). Methods The clinical data of 101 cases undergoing duct-to-mucosa PD in our hospital from January 1994 to January 2008 were reviewed retrospectively. Results The incidence of pancreatic fistula was 9.9% (10/101). Univariate analysis showed level of preoperative jaundice(χ2=5.814, P= 0.016) , duration of jaundice (χ2= 4.17, P = 0.041 ), texture of the remnant pancreas (χ2=5.286, P = 0.021 ), diameter of pancreatic duct (χ2= 4.165, P = 0.041 ), blood loss during operation (χ2=5.273, P=0.022) were significantly associated with pancreatic fistula after duct-to-mucosa PD. Multivariate analysis regression revealed that texture of the remnant pancreas (OR = 13.355, P = 0.023), level of preoperative jaundice (OR = 12.126, P = 0.006), blood loss during operation (OR = 5.92, P =0.032 ) were independent risk factors. Logistic regression equation was as following: P=1/[<1+e-(-6.378+2.592 texture of the remrant pancress + 2.495 level of preopetative jaundice + 1.778 blood loss during operative)>]. The accuracy of the logistic equation was 92.1%. Conclusion Texture of the remnant pancreas, level of preoperative jaundice, blood loss during operation were the independent risk factors for the occurrence of PD after duct-to-mucosa PD. Improvement of operative technique and reduction of blood loss can decrease the incidence of pancreatic fistula.

Cardiovascular disease (CVD) remains the leading cause of death worldwide. Therefore, exploring the mechanism of CVDs and critical regulatory factors is of great significance for promoting heart repair, reversing cardiac remodeling, and reducing adverse cardiovascular events. Recently, significant progress has been made in understanding the function of protein kinases and their interactions with other regulatory proteins in myocardial biology. Protein kinases are positioned as critical regulators at the intersection of multiple signals and coordinate nearly every aspect of myocardial responses, regulating contractility, metabolism, transcription, and cellular death. Equally, reconstructing the disrupted protein kinases regulatory network will help reverse pathological progress and stimulate cardiac repair. This review summarizes recent researches concerning the function of protein kinases in CVDs, discusses their promising clinical applications, and explores potential targets for future treatments.

Objective:To investigate the association between body mass index (BMI) trajectories in children and adolescents and subclinical renal damage (SRD) in adulthood.Methods:4 623 participants aged 6-18 years old were recruited from the ongoing cohort of Hanzhong adolescent hypertension study in 1987, and the subjects were followed up in 1989, 1992, 1995, 2005, 2013 and 2017, respectively. Group-based trajectory modeling was used to identify distinct BMI trajectories in longitudinal analysis. Generalized linear model was applied to examine the association between different BMI trajectories and SRD incidence in adulthood.Results:A total of 2 678 subjects from childhood to adulthood were enrolled in this study. All subjects were divided into three groups according to three distinct BMI trajectories: low-increasing BMI group ( n=1 017), moderate-increasing BMI group ( n=1 353), and high-increasing BMI group ( n=308). Over follow up for 30 years, a total of 248 participants (9.3%) developed SRD. Urinary albumin-to-creatinine ratio (uACR) in low to high-increasing BMI group was 0.9(0.6, 1.4), 1.0(0.7, 1.7), 1.6(0.8, 3.2), respectively ( P trend<0.001), and estimated glomerular filtration rate was 98.5(87.6, 111.6) , 96.2(86.4, 109.7), 95.3 (87.5, 125.0) ml·min -1·(1.73 m 2) -1, respectively ( P trend=0.025). The generalized linear model analysis showed that uACR was increased linearly from low to high-increasing BMI group [ β=3.16(95% CI 1.02-5.31), Ptrend=0.004]. There was no correlation or linear trend between BMI trajectory and estimated glomerular filtration rate [ β=-2.30(95% CI-5.18-0.57), Ptrend=0.117]. Compared with the low-increasing BMI group, the high-increasing BMI group had greater odds of experiencing SRD in adulthood after adjusting for multiple confounders such as age, gender, medical history and lifestyle ( OR=2.83, 95% CI 1.84-4.36, Ptrend<0.001). Conclusions:Higher BMI trajectorie is correlated with higher level of uACR and risk of SRD in middle age. Identifying long-term BMI trajectorie from early age may assist in predicting individuals′ renal function in later life.

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

【Objective】 Based on our previously established salt-sensitive hypertension cohort, we conducted chronic salt loading and potassium supplementation interventions, aiming to examine the association between genetic variants in renalase and blood pressure (BP) responses to dietary interventions of salt and potassium intake. 【Methods】 In 2004, 514 subjects from 126 families were recruited in Shaanxi Province to establish the salt-sensitive hypertension study cohort. Among them, 334 non-parent subjects were selected and sequentially maintained on a low-salt diet for 7 days, then a high-salt diet for 7 days and a high-salt diet with potassium supplementation for another 7 days. Ten single nucleotide polymorphisms (SNPs) in the renalase gene were genotyped on the MassARRAY platform. 【Results】 SNP rs2576178 of the renalasegene was significantly associated with systolic BP (SBP) and mean arterial pressure (MAP) responses to low-salt intervention (SBP: β=-2.730, P<0.05; MAP: β=-1.718, P<0.05). In addition, SNP rs12356177 was significantly associated with diastolic BP response to low-salt diet (β=-1.608, P<0.05). However, we did not find any association for the renalase SNPs with BP response to high-salt diet with potassium supplementation reached nominal statistical significance. 【Conclusion】 Genetic variants in renalase gene are significantly associated with BP response to low-salt diet, suggesting that renalase may be mechanistically involved in BP salt-sensitivity.
