Objective To observe the clinical efficacy and safety of prednisone and mycophenolate mofetil in treatment of IgA mesangial proliferative glomerulonephritis.Methods Ninety-six cases of IgA mesangial proliferative glomerulonephritis were divided into control group and treatment group with 48 cases each.The patients in two groups were given conventional treatment and prednisone [prednisone usage of 0.5mg/ (kg ·d),4 weeks after the gradual reduction of weekly 5-10 mg/d].On this basis,the patients in treatment group were given mycophenolate mofetil [1.5 g/d (before 6 months) ; 1.0 g/d (6-12 months) ; 0.5g/d (12 months)].The clinical efficacy,physiological indicator and adverse reactions in two groups were observed.Results The total effective rate was 87.5％(42/48) in treatment group and 60.4％ (29/48) in control group,and there was significant difference (P ＜0.05).There was no significant difference in the physiological indicator before treatment between two groups (P ＞ 0.05).The urine volume,urine protein,albumin,blood creatinine and total cholesterol after treatment in treatment group was improved compared with that in control group [(1812 ± 355) ml/24 h vs.(1365 ± 287) ml/24 h,(2.2 ± 0.6) g/24 h vs.(3.3 ±0.6) g/24 h,(30.2 ±3.1) g/L vs.(21.9 ±4.6) g/L,(116.5 ±9.9) μmol/L vs.(143.5 ± 10.6) μmol/L,(4.7 ± 0.8) mmol/L vs.(5.8 ± 0.7) mmol/L],and there was significant difference (P ＜ 0.05).There were no serious adverse reactions in the beth groups.Conclusion Prednisone and mycophenolate mofetil can improve renal function in patients with IgA mesangial proliferative glomerulonephritis and achieve better clinical efficacy with less adverse reactions.It should be widely applied.

Objective To find out about the current situation of mental health institutions in Guangdong. Methods An investigation via self-made questionnaires was made on the current situation of 62 mental health institutions in the province and a comparison was made of 22 mental hospitals between now and four years ago. Results Throughout the province, there were 9901 psychiatric beds, 1236 psychiatric doctors and 1909 psychiatric nurses, averaging respectively 1.16 beds, 0.15 doctors and 0.22 nurses per 10 thousand people. The bed utilization ratio was mostly 82.00% and only 12.00% of the mental health institutions adopted open management. A comparison of the 22 mental hospitals between now and 4 years ago showed that the numbers of hospital beds, doctors, doctors with associate senior professional tides and above, ECG machines, computers, hospital total income per year, and monthly charges for hospitalization had increased while the area of workplaces, the bed utilization ratio, the average number of daily outpatient visits, the average number of daily outpatient psychological consultations, and equipment other than ECG machines and computers remained unchanged and government funding had decreased. Couclusion The major problems with the mental health institutions in the province are shortage and lack of balance in the allocation of mental health resources, backwardness in the modes of management, difficulty in internal development, and reduction of government input.

Objective To discuss the imaging manifestations of chordoma.Methods The imaging manifestations of chordoma in 42 cases proved by surgery and pathology were retrospectively analysed.Results The lesions located at the region of skull base in 23 cases(54.8%),at the sacrococcygeal region in 18 cases(42.9%) and one case(2.3%) outside the axial skeleton as an extra-axial chordoma or parachordoma.Bone destruction in the areas near skull base and sacrococcygeal region could be found on radiography.On CT,chordoma typically appeared as a expansile soft-tissue mass that arises from the clivus and sacrococcygeal region with associated extensive lytic bone destruction.MR imaging was considerably superior to CT in the delineation of lesion extent.Conclusion Chordoma has typically distribution and characteristic imaging manifestations,especially MRI.

Objective To explore the clinical efficacy and safety of leflunomide combined with prednisone in the treatment of immunoglobulin A nephropathy.Methods 80 patients with IgA nephropathy were chosen and randomly divided into two groups,40 cases in each group.The control group was orally given prednisone(initial dose 1 mg · kg-1 · d-1),after 2 months of treatment 5mg/2 weeks reduction,and 10mg/d as maintenance therapy,while the observation group was treated with 20mg/d leflunomide treatment based on the treatment of control group.All the two groups had 3 months as a course of treatment.Before treatment and after treatment,the 24h urinary protein,serum albumin,serum creatinine,glomerular filtration rate,cholesterol,triglycerides,cystatin C levels and urinary vascular cell adhesion molecule-1 after treatment (urinary VCAM-1) and interleukin-18 (IL-8) in the two groups were recorded and compared,as well as the clinical efficacy and adverse reactions.Results The total effective rate in the observation group was 92.5％,which was significantly higher than 75.0％ in the control group (x2 =4.501,P ＜ 0.05).After treatment,the serum creatinine,serum albumin,cholesterol,triglycerides,cystatin C,24h urine protein,glomerular filtration rate and urinary VCAM-1,IL-8 in the two groups were all significantly improved (t ≥ 1.945,all P ＜ 0.05).After treatment,the cholesterol and triglycerides in the two groups had no significant differences (t =0.322,1.307,all P ＞ 0.05).After treatment,in the observation group,the serum creatinine,cystatin C,24h urinary protein excretion,VCAM-1 and IL-8 in urine were significantly lower than those in the control group,while serum albumin and glomerular filtration rate were significantly higher (t ≥2.632,all P ＜ 0.05).In the observation group,the total effective rate of Ⅳ,Ⅴ grade by Lee classification were significantly higher (x2 =4.269,4.600,all P ＜ 0.05).And in the two groups,the total effective rate of Ⅰ,Ⅱ grade by Lee classification had no statistically significant differences(x2 =0.000,0.000,all P ＞0.05).In the observation group,the incidence rate of adverse reaction was 10.0％,that in the control group was 8.6％,there was no statistically significant difference between the two groups (x2 =0.157,P ＞ 0.05).Conclusion Leflunomide combined with prednisone in the treatment of IgA nephropathy has better clinical efficacy and higher safety,its mechanism may be associated with decreased urinary VCAM-1 and serum IL-18 levels.

Objective To study the iodine deficiency disorders (IDD) situation in Wenzhou City during 1995-2014.Method According to National IDD Surveillance Project,IDD surveillance had been consecutively carried out during the past 20 years,which consisted of goiter rate in 8-10 years old children,iodized salt and urinary iodine levels.Results The goiter rate of 8-10 years old children was decreased from the highest of 31.09％ (2 190/7 043) in 1995 to the lowest of 2.28％ (77/3 378) in 2014;the highest level of median urinary iodine was 214.78 μg/L,and the lowest level was 74.48 μg/L,and which was increased from 74.48 μg/L in 1995 to 187.00 μg/L in 1996,and then had been maintained at the appropriate level recommended by World Health Organiation (WHO),except that in 1998,2003,2004 and 2006.The qualified rate of iodized salt was increased from 54.95％ (1 471/2 677) in 1996 to 95.52％ (2 548/2 754) in 1999,but decreased to 62.75％ (768/1 224) in 2003,however it was fluctuated from 78.61％ (2 503/3 184) to 92.48％ (2 989/3 232) from 2004 to 2013,and it was 90.43％ in 2014 (2 983/3 300).Conclusions The comprehensive measures for controlling IDD,with universal salt iodization,has been gradually achieved remarkable effect in Wenzhou City,but the non-iodization salt existing in the market is still a problem,and people have misunderstandings about iodization salt.Iodine supplementation had better be conducted according to local conditions and based on scientific policy.

Objective To search specific biomarkers of pathogenic bacteria in patients with sepsis so as to guide early using rationally antibiotic treatment.Methods Prospective survey of 147 patients with sepsis in ICU was carried out from Jan 2012 to Mar 2015.When patients blood culture was positive, clinical data including age, gender, vital signs, blood and, urine routine examination, DIC, blood biochemistry, c-reactive protein (CRP), procalcitonin (PCT), microbial detection, etc were recorded.Cultured blood samples were from central venous catheter and peripheral vessel.ELISA method was employed to detect soluble toll-like receptor 2 ( sTLR2 ) and interleukin-8 ( IL-8 ) , and the Acute Physiology and Chronic Health Evaluation Ⅱ( APACHEⅡ score ) was calculated.The chi-square test and analysis of variance were performed where necessary.Receiver operating characteristic ( ROC ) curves were used to calculate cut-points ( CP ) and area under the curve ( AUC) .Results According to the results of blood culture, patients were divided into three groups:GP group [ gram-positive bacteria ( G+) group];GN group [ gram-negative bacteria ( G-) group];FG group ( fungi group) .There were no significantly statistical differences in age, APACHEⅡ score, vital signs and markers of inflammation among three groups (P>0.05).Gram negative pathogenic bacterium was the most common microbe.Compared with GN group, the level of sTLR2 in the GP group was obviously higher ( P=0.000); but there was no significant difference in sTLR2 level between GP group and FG group (P=0.187). The amount of (1, 3) -beta glucan in the FG group was significantly higher than that in the GP group ( P=0.000).The sTLR2 level in FG group was obviously higher than that in the GN group (P=0.000).There were no significantly statistical differences in PCT, CRP and IL-8 among the three groups (P>0.05).For the diagnosis of gram negative bacteria infection, sTLR2 area under the curve was 0.768, and the sensitivity and specificity were 88.90%and 59.60%, respectively and the best cut-off point was 8.083 pg/mL.Namely, the diagnosis of gram negative bacteria infection was less likely, when level of sTLR2 was higher than 8.083 pg/mL.The markers of PCT, CRP, (1, 3) -beta glucan and IL-8 were less valuable for the diagnosis of Gram negative bacteria infection because the area under the curve was less than 0.5.Conclusions The combination of inflammatory indicators such as sTLR2 and (1, 3) -beta glucan etc, can imply the kind of pathogenic microorganisms partly.

Objective To discuss the curative effects of alfacalcidol combined with losartan potassium tablets in the treatment of early diabetic nephropathy (EDN).Methods 90 EDN patients in our hospital were chosen and randomly divided into the observation group and control group (45 cases in each group).The control group was given losartan potassium tablets treatment,while the observation group was given alfacalcidol combiend with telmisartan treatment.All the two groups were treated for 3 months.Before and after treatment,the fasting blood glucose (FBG), 24h urine trace albumin quantitative (UAER),24h urine protein (24h pro),serum creatinine (SCr),25 -hydroxyl vitamin D [2 5 (OH )D ],blood calcium (Ca2+),potassium (K+),glycosylated hemoglobin (HbA 1 C )and serum inflammatory factors[C-reactive protein (CRP),tumor necrosis factor alpha (TNF-α),interleukin-6 (IL-6 )] were observed,and the correlation between 25 (OH)D and UAER,24h pro was analyzed.At the same time,the clinical curative effects and adverse reactions during treatment were evaluated.Results In the observation group,the total effective rate was 93.3%,which was significantly higher than 71.1% in the control group (χ2 =7.601,P<0.05).In the two groups after treatment,the FBG,HbA1c,blood Ca2+and K+had no significant changes (all P>0.05).After treatment,Scr,24h pro and UAER in the two groups were all significantly reduced compared with before treatment (P<0.05),and 24h pro and UAER in the observation group were significantly lower than those in the control group (t=6.296,11.530,all P<0.05),but Scr had no statistically significant difference between two groups (t=0.331,P>0.331).After treatment,25(OH)D in the observation group decreased significantly compared with before treatment (t=12.000,P<0.05),which was significantly higher than that in the control group after treatment (t=11.278,P<0.05).Compared with before treatment,25(OH)D in the control group had no significant change after treatment (t=0.436,P>0.436).Pearson correlation analysis showed that 25 (OH)D level was negatively correlated with 24h pro and UAER (r=0.483,0.778,all P<0.05 ).In the two groups after treatment,the CRP, TNF-αand IL-6 levels significantly reduced (P<0.05 ),which in the observation group decreased more obviously (all P<0.05).In the two groups,no serious adverse events were found,the difference was not statistically significant (χ2 =0.212,P >0.151 ).Conclusion Alfacalcidol combined with losartan potassium tablets can significantly reduce the proteinuria levels of EDN patients and inflammation,which has better clinical curative effects and higher safety.

Object To observe the effects of coumarin (CM) and Verapamil (Ver) on contractivity and its relationship with Ca 2+ in isolated ileal smooth muscle of the rabbits. Methods The effects of CM and Ver were observed in three doses by routine experimental methods in isolated rabbit ileal. Results CM and Ver inhibited the contraction of isolated ileal smooth muscle induced by acetylcholine and CaCl 2. The responses were a concentration-dependent and non-competitive manner. CM and Ver were effective against the initial and sustained peak induced by acetylcholine. Conclusion CM has a calcium-antagonistic effect which is similar to that of Ver.
