In patient with primary biliary cirrhosis,the metabolism of calcium and vitamin D could be affected and osteomalacia and secondary hyperparathyroidism might occurr.Besides,hypoalbuminemia may mask the real level of serum calcium and thus lead to misdiagnosis of coexisting parathyroid adenoma.Therefore,a rare case of parathyroid adenoma associated with primary biliary cirrhosis was herewith presented to call attention to the effect of hypoalbuminemia on serum calcium.

Objective To explore the clinical application of the multi-network anatomical lavage on the treatment of chronic osteomyelitis after fracture surgery. Methods A retrospective analysis of 40 patients (41 sites) with chronic osteomyelitis after fracture surgery was performed from June 2006 to December 2008. There were 35 males and 5 females with an average of 42.7 years (range, 16-68). All 40 cases were treated with debridement, closing the cavity, and placing the multi-tube drainage network anatomical catheter lavage system. At the same time, sensitive antibiotics were used for 3 to 4 weeks. Rechecks were scheduled every 3 months after operation, including wound healing, X-ray presentation, ESR and C-reactive protein.Cure criteria depends on the conditions of the inflammation when the lavage treatment was over, and whether it relapsed six months after operation, including wound healing, systemic symptoms, ESR and C-reactive protein. Results Judged by the clinical outcomes when the lavage treatment was over and six months after operation, the effects were categorized into 3 levels, including excellent in 37 cases with primary wound healing, and without relapse six months later;, good in 2 with poor wound healing, the wound healed after a period of treatment without recurrence; poor in one with recurrent sinus infection and a prolonged unhealed wound, after another operation he was healed. 36 cases were treated with bone graft and internal fixation operation, and the fractures were healed after surgery, the fractures were healed directly in 4 cases without bone graft. The patients were followed up for an average of 43.2 months (range, 30-50) after operation, and none relapsed. Conclusion The multi-tube drainage network anatomical method is feasible and effective on the treatment of chronic osteomyelitis after fracture surgery with a high cure rate.

Objective The present study is to investigate IL-24 gene(Ad5F35-hIL-24) effect on the topoisommeraseⅡα(topoⅡα) and Caspase-3 expression in glioma cell line U251. Methods After transfected the U251 glioma cells with the Ad5F35-hIL-24, the methyl thiazolyl tetrazolium (MTT) was used to analyse the inhibition rate of Ad5F35-hIL-24 on the cells. Hoechst 33258 fluorescent staining and flow cytometric assay were used to detect apoptosis. The immunohistochemistry assay was used to detect topoⅡα expression, and Western blotting was applied to detect the protein expression of topoⅡα and caspase-3. Transwell experiment was used to test the invasiveness of the cells. Results It was found that the Ad5F35-hIL-24 could inhibit U251 cell proliferation and induce apoptosis in a dose dependent manner compared with the control groups. It showed that Ad5F35-hIL-24 could inhibit topoⅡα expression reveled by immunohistochemistry and Westeren blotting, while it increased caspase-3 protein expression. The Transwell experiment showed that the Ad5F35-hIL-24 could reduce the invasiveness of the U251 glioma cells.Conclusion The exogenous IL-24 gene can inhibit the cell proliferation and induce apoptosis of U251 glioma cells. The topoⅡα and Caspase-3 are the important molecular targets of the IL-24 gene. These results may give support for the IL-24 gene usage in clinical treatment for glioma patients.

Objective To explore the value of dual-source CT spectrum energy curve and iodine quantification in determining the degree of differentiation of clear cell renal carcinoma(ccRCC).Methods The radiographic data of 38 cases with pathologically confirmed ccRCC were analyzed retrospectively.All patients underwent dual-source CT,cortical phase and nephrographic phase dual energy scan,including 22 well-moderated differentiated(gradeⅠ,gradeⅡ)and 16 poorly differentiated neoplasms(gradeⅢ,gradeⅣ).The slope of spectrum energy curve (40-70 keV,70-100 keV,100-140 keV)and the normalized iodine concentration (NIC)between the two grades were compared. Results In the spectrum energy curve 40-70 keV and 70-100 keV segment interval,the slope of spectrum of well-moderated differentiated group was higher than that of poorly differentiated group,the difference was statistically significant(P<0.05).In the 100-140 keV segment interval,the slope of spectrum of well-moderated differentiated group was higher than that of poorly differentiated group, but the difference was insignificant(P>0.05).The NIC of well-moderated differentiated group was significantly higher than that of poorly differentiated group(P<0.05).Conclusion The slope of spectrum energy curve and NIC are correlated with the differentiation degree of ccRCC.The slope of spectrum energy curve and iodine quantification of dual-source CT could be used as new methods for preoperative grading of ccRCC.

Objective To investigate the relationship between dyslipidemia and nephrolithiasis in a population-based study.Methods All participants were investigated by questionnaires,physical examinations and laboratory tests including liver and renal function,lipid profile,serum fasting glucose,glycosylated hemoglobin.Nephrolithiasis was diagnosed by kidney Bultrasonography.Subjects with estimated glomerular filtration rate (eGFR) ＜ 60 ml · min-1 · (1.73 m2)-1were excluded.Results 10 316 individuals were enrolled with an average age of (54.88 ± 10.27) years (range 17-88 years) and the ratio of male to female 1:1.12.The prevalence of nephrolithiasis was 5.6％,3.7％ and 7.8％ for whole population,women and men,respectively.In women,only eGFR in stone group was significantly lower than that in non-stone group (P ＜ 0.05).However,participants in stone group were significantly older (P ＜ 0.05),of higher blood pressure (P ＜ 0.01),higher serum uric acid (P ＜ 0.01),worse renal function (serum creatinine,P ＜ 0.05;eGFR,P ＜ 0.01),and higher low-density lipoprotein (LDL) (P ＜ 0.05),compared with those in non-stone group in men.Logistic regression analysis showed that only eGFR (P ＜ 0.05) was the independent influential factor for kidney stones in women;In men,LDL was an independent influential factor for nephrolithiasis with a hazard ratio of 1.149 (95％CI 1.003-1.317,P ＜ 0.05),except for mean blood pressure and eGFR.After being divided into normal group,borderline high group and high LDL group according to the LDL level,with the increase of LDL,the prevalence of nephrolithiasis was significantly increased by 7.3％,8.3％ and 10.6％ in men respectively.There was no significant relationship between total cholesterol,triglyceride,high-density lipoprotein and nephrolithiasis.Conclusions Dyslipidemia is associated with nephrolithiasis in men,and high LDL cholesterol is an independent risk factor for nephrolithiasis.Clinical lipid testing not only helps to reduce the risk of atherosclerotic disease,but also reduces the risk of kidney stones.

Objective:To determine the epidemiology of hyperkalemia and influencing factors in a general population in Pinggu district of Beijing city.Methods:This study was a cross-sectional survey. The subjects were from the epidemiological survey population of chronic diseases in Pinggu district of Beijing city from March to May 2014. All participants completed a questionnaire, anthropological measurement, and venous blood samples collection to detect serum creatinine and potassium and so on. First void morning urine was collected to detect the albumin-creatinine ratio. Hyperkalemia and hypokalemia were defined as serum potassium level>5.0 mmol/L and≤3.5 mmol/L, respectively. Logistic regression analysis method was used to analyze the influencing factors of hyperkalemia.Results:Of the 10 252 people in this study, the prevalence of hyperkalemia was 6.17%(95% CI 5.70%-6.67%), the prevalence of hypokalemia was 0.61%(95% CI 0.47%-0.79%), and the prevalence of participants with serum potassium>5.5 mmol/L was 0.53%(95% CI 0.40%-0.69%). Multivariate logistic regression analysis results showed that males ( OR=1.269, 95% CI 1.074-1.498, P=0.005), diabetes ( OR=1.226, 95% CI 1.008-1.490, P=0.041), increased total cholesterol ( OR=1.219, 95% CI 1.119-1.329, P<0.001), and decreased estimated glomerular filtration rate ( OR=0.971, 95% CI 0.965-0.977, P<0.001) were significantly correlated with the increased risk of hyperkalemia. Usage of renin-angiotensin-aldosterone system inhibitors and diuretics were not found to be significantly associated with the risk of hyperkalemia ( OR=1.018, 95% CI 0.751-1.380, P=0.908; OR=0.638, 95% CI 0.229-1.781, P=0.391). Conclusions:The prevalence of HK in the general population is 6.17%. The male, decreased estimated glomerular filtration rate, diabetes, and increased total cholesterol are influencing factors of hyperkalemia.

Objective:To screen risk factors for carotid plaque vulnerability in patients with ischemic stroke and construct a risk prediction model.Methods:From November 2019 to January 2021, a total of 164 patients with ischemic stroke hospitalized in the Neurology Department of the Affiliated Hospital of Jining Medical University were selected as the study subjects by convenience sampling method. Color doppler ultrasound was used to measure carotid plaques in patients with ischemic stroke to determine whether they were vulnerable plaques. The patients were surveyed using the General Information Questionnaire and the Type D Personality Scale. Binary Logistic regression analysis was used to explore the risk factors of carotid plaque vulnerability in ischemic stroke patients, and based on this, a risk prediction model for carotid plaque vulnerability in ischemic stroke patients was constructed.Results:A total of 87 patients with ischemic stroke had vulnerable carotid plaques. The results of binary Logistic regression analysis showed that age ( OR=1.136, 95% CI: 1.052-1.226), total score of Type D Personality Scale ( OR=1.170, 95% CI: 1.043-1.312), smoking history ( OR=3.058, 95% CI: 1.054-8.875), homocysteine ( OR=1.400, 95% CI: 1.179-1.664), triglycerides ( OR=2.356, 95% CI: 1.534-3.619) were risk factors for carotid plaque vulnerability in stroke patients ( P<0.05). The results of risk prediction model based on risk factors show that, the area under the receiver operating characteristic of the subjects was 0.935, indicating good clinical predictive ability. Conclusions:Age, total score of Type D Personality Scale, smoking history, homocysteine and triglyceride are risk factors of carotid plaque vulnerability in stroke patients. The risk prediction model can early identify and screen high-risk factors for carotid plaque vulnerability in ischemic stroke patients, and is worthy of clinical promotion and practice.
