Objective According to the infrared spectrum of renal stone composition analysis,discuss the relationship between gender,age and kidney stone.Methods Kidney stone composition analysis of 408 cases had been done in our hospital from the 2002 to 2011 by using Fourier transform infrared spectroscopy.There were 271 males (66.4％) and 137 females (33.6％).Results There were 359 cases with calcium stones,accounting for 88.0％ (359/408); 197 cases with calcium oxalate stones alone,accounting for 48.3％; 180 cases with phosphate stones,accounting for 44.1％; 211 cases with mixed composition stones,accounting for 51.7％.Main chemical composition of the stones were:calcium oxalate 48.3％,carbonate apatite 34.8％,urates 5.4％,ammonium magnesium phosphate 4.4％,ammonium carbonate eutectic 3.4％,brushite 1.5％,cystine 2.0％ and protein 0.3％.Male patients accounted for 66.4％ of all cases and the peak onset age was 30-59 years; Female patient accounted for 33.6％ of all cases and the peak onset age was 50-59 years.Conclusions Calcium oxalate and phosphate are the most common components of kidney stones.Males age between 30-59 years and females age between 50-59 years may suffer from of kidney stone formation.

Objective To determine the influencing factors of post-stroke depression by machine learning.Methods Stroke patients' medical records (688 cases eligible) were extracted from record system,including age,gender,pulse manifestation,complexion,tongue quality,fur,Chinese medicine intervention,body mass index (BMI),blood pressure,blood glucose,blood triglyceride,blood total cholesterol,smoking history,drinking history,depression family history,stroke lesion site in imaging,as well as the final depression judgment.Single rule algorithm (1R) was adopted to learn.The risk factors influencing post-stroke patients' depression in extracted information were determined.Then the cases collected were divided into the training dataset (500 cases) and the test dataset (188cases).Optimal discriminant results were obtained by random forest model.Results Single rule algorithm showed that the most important influencing factor of post-stroke depression was stroke lesion site.By computer speculation,stroke lesions in the frontal and temporal lobes were most prone to post-stroke depression.Basal ganglia,brain stem,cerebellum,medulla oblongata and occipital lobe lesions were less likely to cause depression.The accurate classification rate could amount to 88.95％ (612/688 cases).Random forest model determination was made in the former 500cases in the training dataset.The total correct rate of determining depression was 98.2％.The total correct rate of determination in 188 cases of the test dataset was 99.47％.Six hundred and eighty-eight patients' data were learnt by random forest model.The total correct rate was 98.84％.The importance measure results showed that top 3 important indexes of post-stroke depression were lesion site,Chinese medicine intervention and depression family history.Conclusion Patients with lesions in the frontal & temporal lobes and depression family history were most prone to post-stroke depression.

Objective To study the value of PSADT in predicting the prognosis and the possibility of disease progression for patients with prostate cancer after MAB therapy.Methods Based on the retrospective review of the history and the follow-up of 159 prostate cancer patients,who received MAB therapy in our department from January 1994 to December 2010,PSADT values were calculated and survival analysis was performed.The ages at diagnosis ranged from 54 to 90 years with a median of 74 years.The pretreatment PSA value ranged from 2.6 to 275.0 μg/L with a median of 46.8 μg/L.The patients of Gleason score ≤6,7 and ≥8 constituted 27.7％,42.1％ and 25.2％,respectively.Only 26.4％ of the patients were staged as T1N0M0-T2N0M0 and the others had locally advanced disease or metastasis.A multivariate analysis with a Cox's proportional hazard model was used and the disease progression rates in different PSADT groups were also compared.Chi-square test and Log-rank test were applied in statistic analysis.Results The 159 patients received follow-up with a median period of 28 months (6-126 m).The median PSADT of these 159 patients was 5.7 months (0.5-21.0 m).The 3-year and 5-year survival for the 71 patients,whose PSADT were not less than 6 months,were 89.4％ and 47.6％ respectively,compared with 49.8％ and 30.6％ for the other 88 patients whose PSADT were less than 6 months.The survivals were significantly different between the two groups (P ＜ 0.01).It was confirmed by a further multivariate analysis with a Cox' s proportional hazard model that PSADT was one of the predictive factors of the prognosis of these prostate cancer patients with a hazard ratio of 2.6 (P ＜ 0.01).Moreover,disease progression were found in 19.7％ of the PSADT≥6 m group during the follow-up compared with 63.6％ in the PSADT ＜6 m group.The disease progression rates were also significantly different (P ＜ 0.0 l).Conclusions PSADT can be used to predict the prognosis of patients with prostate cancer after the MAB therapy.The survival for the patients,whose PSADT are not less than 6 months,is higher than those whose PSADT less than 6 months.Meanwhile,PSADT can predict the possibility of disease progression after MAB treatment.

Objective To investigate the proportion , risk factors and tendency of change of stone composition in recurrent urolithiasis .Methods Eighty-five recurrent urolithiasis patients from 2002 to 2014 were enrolled in this retrospective cohort study .There were 61 male and 24 female patients with a median age of 51 (21-89) years at initial events.Among those patients, 70 had two events, 12 had three events, and 3 had more than 3 events.Compositions of initial and recurrent stones were measured by infrared spectrophotometry.Stone type, recurrence interval and recurrence frequency were studied as potential risk factors for composition change . Chi square test and logistic regression analysis were employed in the statistical analysis.Results Stone composition changed during recurrence in 26 patients ( 30.6%) . Univariate analysis showed the risk ratio of composition change in the patients with recurrence interval of 1-5 years was 0.518 (95%CI, 0.277-0.967, P<0.05) when compared with those of less than 1 year or more than 5 years.Logistic regression analysis showed the odds ratio of recurrence interval of 1-5 years was 0.231 (95%CI, 0.075-0.707, P=0.010).The mutual conversion between calcium oxalate and infection stones was mostly observed when stone composition changed during recurrence .Twenty percent of calcium oxalate stones changed to infection stones and 29.2% of infection stones changed to calcium oxalate .
Conclusions Stone composition changes in about one third patients of recurrent urolithiasis .The mutual conversion between calcium oxalate and infection stones is the most common change .Recurrence interval is an independent risk factor to predict composition change .Repeated stone analysis should be suggested to patients with recurrent interval of less than 1 year or more than 5 years.

Objective To investigate if distribution of stone composition and onset age in the upper urinary tract changed during the past 12 years in China.Methods There were 1 878 urolithiasis patients of the upper urinary tract in our hospital from 2003 to 2014 enrolled in present cross-sectional study.There were 1 300 male and 578 female patients with a median onset age of 46 (6-95) years.Stone composition was measured by infrared spectrophotometry.All the patients were divided into 3 groups according to the onset year:Year 2003-2006,Year 2007-2010 and Year 2011-2014.The distributions of stone types were compared among the 3 groups.Age and gender were included as potential confounders.Chi square test,P trend test,Kruskal-Wallis test and logistic regression were employed in the statistical analysis.Results Calcium oxalate was the most common type with a dominant proportion of 78.1％ (1 466/1 878),while uric acid had a small proportion of 4.8％ (91/1 878).The proportions of uric acid in the 3 groups were 2.7％ (12/441),5.1％ (39/758) and 5.9％ (40/679),showing an increasing trend (P ＜0.05).Multivariate analysis showed that year group was independently correlated with the proportion of uric acid,with an OR of 1.385 (95％ CI,1.027-1.867).From 2003 to 2014,the proportion of uric acid calculus increased by 0.42％ (95％ CI,0.25％-0.59％) annually.The median ages of disease onset were 43,46 and 49 years respectively in those three groups,also showing an increasing trend with time (P ＜0.01).Conclusion From 2003 to 2014,the proportion of uric acid and onset age in patients of upper urinary tract calculi were increased in the present cohort.

Objective To investigate the influence of Guhong injection (GHI) on ATPase activity and inflammatory response after cerebral ischemia/reperfusion (I/R) injury in rats, and evaluate its protective effects on cerebral I/R injury. Methods Seventy-two male Sprague-Dawley (SD) rats were divided into sham group, I/R group, nimodipine group, and the low-dose (2.5 mL/kg, GHI-L), medium-dose (5.0 mL/kg, GHI-M), and high-dose (10.0 mL/kg, GHI-H) of GHI groups according to the random number table method, with 12 rats in each group. The middle cerebral artery occlusion (MCAO) model was established by the intraluminal suture method to prepare the model of focal cerebral ischemia, and reperfusion was performed after 1.5 hours of occluding the middle cerebral artery; the sham group had the same operation process except inserting the nylon thread. The injection of drug in various drug-treated groups was carried out via a tail vein at 0, 12, 24 hours after the onset of reperfusion, while the sham group and I/R group received the same amount of normal saline. At 12 hours after last drug administration, the scores of neurological deficit symptoms were evaluated; the cerebral infarction was observed by triphenyl tetrazolium chloride (TTC) staining; the Na+-K+-ATPase and Ca2+-ATPase activities in the brain tissue were measured by phosphorus determination; the contents of interleukin-6 (IL-6), monocyte chemotactic factor-1 (MCP-1), nitric oxide (NO) in serum were detected by enzyme linked immunosorbent assay (ELISA). Results Compared with the sham group, the neurological function score was significantly decreased, the cerebral infarction was serious, the activities of ATPase was obviously decreased, and the levels of serum inflammatory factors were significantly increased in I/R group. Compared with the I/R group, the neurological function scores were significantly increased in GHI-L group, GHI-M group, GHI-H group and nimodipine group (9.03±0.63, 10.54±2.55, 12.33±1.87, 12.06±1.89 vs. 8.17±1.05, all P < 0.05), the volumes of cerebral infarction were obviously reduced [(18.51±1.80)%, (15.98±1.34)%, (8.61±1.16)%, (8.09±0.96)% vs. (26.52±2.07)%, all P < 0.01], the activities of ATPase were significantly increased [Na+-K+-ATPase (μmol·mg-1·h-1):5.10±0.30, 5.34±0.26, 6.19±0.17, 5.86±0.31 vs. 3.98±0.35, Ca2+-ATPase (μmol·mg-1·h-1): 3.68±0.44, 4.43±0.29, 5.03±0.27, 4.17±0.30 vs. 1.87±0.46, all P < 0.01], and the levels of serum inflammatory factors were decreased obviously [IL-6 (ng/L): 51.61±5.55, 43.88±4.05, 39.71±2.22, 41.28±2.66 vs. 60.11±6.61, MCP-1 (ng/L): 227.82±7.07, 201.58±13.10, 177.23±10.46, 126.80±8.49 vs. 296.01±12.85, NO (μmol/L): 54.48±3.23, 46.84±2.69, 41.15±2.80, 48.62±2.34 vs. 65.25±3.88, all P < 0.05]. Conclusions GHI not only can improve the energy metabolism of brain tissue in a dose-dependent manner, but also inhibit the inflammatory cascade of damage after cerebral I/R in rats, which might be its protective mechanism on cerebral ischemia injury.

From November 2014 to July 2017,637 patients with acute coronary syndrome (ACS) were included in the analysis,among whom there were 48 cases with prior ischemic stroke (7.5％).The risk factors,history,severity of coronary artery disease,medication status,and incidence of adverse cardiovascular and cerebrovascular events (cardiac death,re-infarction,heart failure,stroke) were analyzed.Compare with patients without prior ischemic stroke (control group) patients with prior ischemic stroke (study group) had lower rates in administration of beta blockers [50.00％(24/28) vs.69.78％(411/589),x2=8.02,P＜0.05]and interventional therapy[56.67％(17/30) vs.81.86％(334/408),x2=11.15,P＜0.05].However,there were no significant differences in medication of dual antiplatelet,statins and angiotensin converting enzyme inhibitors or angiotensin receptor blocker between two groups (P＞0.05);and there was no significant difference in major adverse cardiovascular events between two groups (P＞0.05).In the future,more studies are needed for clinical management of this group of patients.

In recent years, minimally invasive surgery has been rapidly developed and has become the first choice for the treatment of moderate to severe benign prostatic hyperplasia (BPH). Although it can significantly improve the lower urinary tract symptoms, reduce complications, and enhance security, postoperative sexual dysfunction(SD) is still common, which affects the patients’ quality of life. In this paper, we discuss the incidence rate of SD after BPH surgery, the protection strategy of sexual function, and how to choose reasonable treatment from the perspective of sexual function protection.
