【Abstract】 Dyslipidemia，especially abnormal levels of cholesterol and/or triglycerides（TG），has become an independent risk factor of atherosclerosis and occurrence and development of coronary heart disease.Chinese guidelines for the prevention and treatment of blood lipid insist that lowering the level of low density lipoprotein cholesterol（LDL-C） is the primary intervention target for preventing atherosclerotic cardiovascular disease（ASCVD） and non-high density lipoprotei cholesterol（non-HDL-C） is the secondary intervention target.At present，the preferred drug for lipid regulation in clinical practice is statins，which may differ due to their different structural characteristics and metabolic mechanisms.This paper focused on the chemical structure，dosage，bioavailability，enzyme binding properties，tissue penetration and t1/2，metabolism，elimination，effectiveness and cholesterol regulation（mainly LDL-C），triglycerides and HDL-C mechanism to compare the similarities and differences between atorvastatin and pitavastatin，providing theoretical basis for clinical individualized medication.

【Abstract】 Background Percutaneous nephrolithotomy（PCNL） is the main method for the treatment of upper urinary calculi，and urinary infection caused by this operation is the most common postoperative complication.In recent years，the drug resistance rate of bacteria has increased year by year，and unreasonable use of drugs after surgery is common.Therefore，how to reduce the incidence of postoperative urinary sepsis，and rational and effective use of antibiotics have important clinical significance.Objective To explore the value of bacteria culture and drug sensitivity analysis of renal pelvis urine and calculi in the prevention of urosepsis after PCNL.Methods A total of 940 patients who were carried out PCNL in Jingzhou Central Hospital were collected for the results of bacterial culture and drug sensitivity test of preoperative midstream urine，intraoperative renal pelvis urine and calculi，and the bacterial species distribution and drug susceptibility test results of the three samples were analyzed from October 2016 to October 2018.According to the drug sensitivity test results of renal pelvis urine and calculi，three non-carbapenems antibiotics with the highest sensitivity were selected.A total of 100 patients with upper urinary calculi with escherichia coli or klebsiella pneumoniae who underwent PCNL surgery in Jingzhou Central Hospital from October 2018 to December 2018 were collected.According to whether antibiotics sensitive to bacteria in renal pelvis urine and calculi were used intraoperatively or postoperatively，the patients were divided into control group and experimental group with 50 patients in each group.The patients in control group were treated with sensitive non-carbapenem antibiotics indicated by mid-stage urine culture and drug sensitivity before and after operation，and the patients in experimental group treated with sensitive antibiotics by midstream urine culture + drug sensitivity test in preoperative period，and non-carbapenems antibiotics sensitive to renal pelvis urine and calculi culture in intraoperative/postoperative period.The incidence of urosepsis after one week of PCNL was observed in the two groups.Results Among 940 patients，171 cases had positive culture result in the preoperative midstream urine，210 cases had positive culture result in the intraoperative renal pelvis urine，and 182 cases had positive culture result in the intraoperative calculi.Escherichia coli and klebsiella pneumoniae were the main bacterial species cultured from midstream urine，renal pelvis urine and calculi.Among the drug sensitivity test results of escherichia coli cultured in preoperative midstream urine，Ceftazidine，Cefoxitin and Minocycline were the most sensitive antibiotics of non-carbapenems，and among the drug sensitivity test results of escherichia coli cultured in intraoperative renal pelvis urine and calculi，Piperacillin/Tazobatam，Cefoperazone/Sulbactam and Amikacin were the most sensitive antibiotics of non-carbapenems.Among the drug sensitivity test results of klebsiella pneumoniae cultured in preoperative midstream urine，Levofloxacin，Cefoxitin and Sulfamethoxazole were the most sensitive antibiotics of non-carbapenems，and among the drug sensitivity test results of klebsiella pneumoniae cultured in intraoperative renal pelvis urine and calculi，Piperacillin/Tazobatam，Cefoperazone/Sulbactam and Amikacin were the most sensitive antibiotics of non-carbapenems.There were statistically significant differences in the sensitivity rates of escherichia coli to Ceftazidime，Cefoxitin and Minocycline in preoperative midstream urine，intraoperative renal pelvis urine and calculi（P<0.01）．Among them，the sensitivity rate of escherichia coli to Ceftazidime，Cefoxitin and Minocycline in intraoperative renal pelvis urine and calculi was lower than that in preoperative midstream urine（P<0.01），but there was no statistically significant difference in the sensitivity of escherichia coli to Ceftazidime，Cefoxitin and Minocycline in intraoperative renal pelvis urine and calculi（P>0.01）．There were statistically significant differences in the sensitivity rates of klebsiella pneumoniae to Levofloxacin，Cefoxitin and Sulfamethoxazole in preoperative midstream urine，intraoperative renal pelvis urine and calculi（P<0.05）．Among them，the sensitivity rate of klebsiella pneumoniae to Levofloxacin，Cefoxitin and Sulfamethoxazole in intraoperative renal pelvis urine and calculi was lower than that in preoperative midstream urine（P<0.01），but there was no statistically significant difference in the sensitivity of klebsiella pneumoniae to Levofloxacin，Cefoxitin and Sulfamethoxazole in intraoperative renal pelvis urine and calculi（P>0.01）．The incidence of urosepsis 1 week after PCNL was 26.0%（13/50） in the control group and 10.0%（5/50） in the experimental group.The risk of urosepsis 1 week after PCNL was higher in the control group than that in the experimental group〔RR=2.600，95%CI（1.002，6.750），P<0.05〕.Conclusion The use of antibiotics sensitive to bacteria in intraoperative pyelolithiasis and calculi can reduce the incidence of urinary sepsis after PCNL.In PCNL，the bacterial culture and drug sensitivity test of renal pelvis urine and calculi should be performed routinely.

【Abstract】 Background To satisfy the needs of increased diabetic population，blood glucose monitoring equipments are becoming increasingly diverse.Accurately quantifying the level of diabetic patients' satisfaction with such equipments is of great significance in motivating their enthusiasm in glycemic management.The Glucose Monitoring Satisfaction Survey（GMSS），a scale has been proved to have good reliability and validity in countries such as the United States，Denmark and so on，but its applicability to China has not been tested.Objective To test the reliability and validity of the Chinese version of GMSS in China's diabetic population.Methods After obtaining the consent of the authors of the GMSS，we developed the initial Chinese version of the GMSS（consisting of GMSS-T1DM and GMSS-T2DM） on the basis of forward translation and back-translation with the help of two bilingual scholars，then developed the final version after two times of revision based on two rounds of 8 diabetes expertsd consultation（the first revision was performed according to the experts' evaluation of the content validity and cross-cultural adaptation of the initial version and corresponding suggestions，and their evaluation scores for the association of each item with the satisfaction with the monitoring system，and then this revised version was evaluated again by the experts，and the second revision was based on the experts' second evaluation scores） and calculating the content validity of the revised version.By use of convenience sampling，475 eligible patients with type 1 or type 2 diabetes were recruited from 3 communities in Beijing（Yijiefang Community，Erjiefangdong Community and Tiancunlu Subdistrict Community） from June to October 2018，and were surveyed with the General Data Questionnaire，Chinese version of GMSS，5-item World Health Organization Well-Being Index（WHO-5），Blood Glucose Monitoring System Rating Questionnaire（BGMSRQ），and Diabetes Distress Scale（DDS）.The general data of the patients were analyzed.Pearson correlation coefficients of the scale and subscale scores of the Chinese version of GMSS-T1DM and GMSS-T2DM with the scores of the WHO-5，BGMSRQ and DDS were calculated to evaluate the criterion validity of the Chinese version of GMSS.And the structural validity and internal consistency reliability of the Chinese version of GMSS were evaluated by using exploratory factor analysis and calculating the Cronbach's α coefficient，respectively.Two weeks later，the Chinese version of GMSS was retested for evaluating its test-retest reliability in 30 of the respondents of the first survey randomly selected in accordance with the proportion of sample size of each community.Results Altogether，463（97.47%） responded effectively to the first survey，including 256 with T1DM，and 207 with T2DM.The average CVI values for the Chinese version of GMSS-T1DM and GMSS-T2DM were 0.910，0.925，respectively.The scale score of the Chinese version of GMSS-T1DM，and the scores of two subscales，openness and trust，were positively associated with the scale scores of WHO-5 and BGMSRQ，and negatively associated with the scale score of DDS-T1DM，while the scores of emotional burden and behavioral burden subscales were negatively associated with the scale scores of WHO-5 and BGMSRQ，and positively associated with the scale score of DDS-T1DM（P<0.05）.The scale score of the Chinese version of GMSS-T2DM，and the score of openness subscale were positively associated with the scale scores of WHO-5 and BGMSRQ，and negatively associated with the scale score of DDS-T2DM，the scores of emotional burden and behavioral burden subscales were negatively associated with the scale scores of WHO-5 and BGMSRQ，and positively associated with the scale score of DDS-T2DM，and the score of worthwhileness subscale was positively associated with the scale scores of WHO-5，BGMSRQ and DDS-T2DM（P<0.05）.By exploratory factor analysis，four common factors were extracted from each of the Chinese version of GMSS-T1DM and GMSS-T2DM，with loading ranged from 0.612 to 0.913，explaining 66.500% of the total variance of the former，and 67.650% of the total variance of the latter，respectively.The Cronbach's α coefficients for the Chinese version of GMSS-T1DM，and its openness，emotional burden，behavioral burden and trust subscales were 0.87，0.82，0.83，0.81 and 0.83，respectively.The Cronbach's α coefficients for the Chinese version of GMSS-T2DM，and its openness，emotional burden，behavioral burden，and worthwhileness subscales were 0.90，0.81，0.80，0.84 and 0.85，respectively.The test-retest reliability and split-half reliability were 0.86，0.89，respectively for the Chinese version of GMSS-T1DM，and were 0.91 and 0.90，respectively for the Chinese version of GMSS-T2DM.Conclusion Both the Chinese version of GMSS-T1DM and GMSS-T2DM have good content validity，criterion validity，structural validity and internal consistency reliability，so they can be used for evaluating diabetic patients' satisfaction with the blood glucose monitoring system.

【Abstract】 To optimize the allocation of medical resources，local governments have successively explored the implementation of the family doctor system in practice in recent years.Although the family doctor system has achieved certain success in some cities，such as Beijing，Shanghai，Chengdu and so on，there are still many problems which restrict the development of family doctor system.Although some literature has pointed out problems in one or several aspects of the family doctor system，it lacks a unified analytical framework.The chronic care model（CCM） has achieved good practical results abroad in which the nurses mainly undertake the tasks of the medical team while the family doctor system in China is based on general practitioners.Both of them are implemented in primary health care institutions，so the effective working mechanism and process design of CCM can provide guidance for improving the family doctor system.Under the framework of the CCM and through theoretical research，this paper finds there are still some shortcomings of the family doctor system in the personnel and process of the service delivery system，the coordination of medical service organizations，the self-management support for patients，the construction of medical information system，decision support，resource allocation，and policy support that impede the advancement of the family doctor system.On the basis of the CCM，this paper proposes some suggestions combined with the practice of the family doctor system in several cities for its future development and improvement，including improving the medical service process with an efficient team，promoting hierarchical diagnosis and treatment system to strengthen the coordination of the medical service organizations，educating patients and paying attention to their self-management，using internet technology to improve the medical information system，increasing policy support to promote the allocation of medical resources.
