Objective To discuss the effect of the calcaneocuboid joint arthrodesis on the weight- bearing area of subtalar joint and its clinical significance.Methods Twelve fresh-frozen cadaver foot specimens were used for determination of weight-bearing area of the subtalar joint on foot and ankle neutral position,dorsiflexion,plantoflexion,adduction,abduction,inversion and eversion motion by means of pressure sensitive film before and after calcaneocuboid joint arthrodesis under weight loading.Results Weight-bearing area of the subtalar joint averagely increased for (32.54?7.45)% in all positions after calcaneocuboid joint arthrodesis,with statistical significance (P＜0.05).Conclusion Weight-bear- ing area of the subtalar joint increases after calcaneocuboid joint arthrodesis,which contributes to decrea- sing the pressure and increasing the stability of the subtalar joint.

BACKGROUNDPolypharmacy and potentially inappropriate medications (PIMs) are prominent prescribing issues in elderly patients. This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-79 years of age and 80 years or older, who were discharged from Geriatric Department in West China Hospital.

METHODSA large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively, 618 patients were 65-79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the American Geriatric Society was applied to assess the use of PIM among the investigated samples.

RESULTSA review of the prescribed medications identified 686 patients aged 80 years or older consumed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (χ2 = 40.18, P < 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P < 0.001). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication.

CONCLUSIONSThe finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.

OBJECTIVETo study the effect of pGCsi-H1-APRIL on the growth of human colorectal cancer cells in transplated tumor in nude mice and to improve the effect of APRIL on proliferation and apoptosis of colorectal cancer (CRC).

METHODSHuman CRC model was established in nude mice, and the nude mice were treated with APRIL siRNA twice per week for 2 weeks. APRIL mRNA expression was surveyed by PCR and APRIL protein expression was detected by immunohistochemistry. The expression of PCNA protein was detected by ELISA. The expression of bcl-2 and bcl-xl was assessed by immunohistochemical staining, and TUNEL staining was used to detect apoptosis.

RESULTSThe expression of APRIL mRNA in the APRIL siRNA group was (0.13 ± 0.05) × 10(-3), significantly lower than that in the vector group (0.95 ± 0.04) × 10(-3) and the PBS group (0.96 ± 0.05) × 10(-3). The expression of APRIL protein in the APRIL siRNA group was (87.5 ± 5.0)% lower than that in the vector and PBS groups (P < 0.05). APRIL siRNA significantly suppressed the growth of SW480 tumor: the IR (inhibitory rate) of APRIL siRNA group was (60.7 ± 1.5)% (P < 0.05). The expression of PCNA in APRIL siRNA group was (176.8 ± 18.1) ng/ml, was (56.5 ± 2.0)% lower than that of PBS group (328.4 ± 22.8) ng/ml. Furthermore, the expressions of anti-apoptosis proteins bcl-2 and bcl-xl of APRIL siRNA group were (82.6 ± 4.5)% and (79.2 ± 3.5)% lower than those of the PBS group. The apoptotic rate of the APRIL siRNA group was 40.1% ± 2.5%, significantly higher than that in the vector group (2.5 ± 0.1)% and PBS group (2.5 ± 0.2)% (P < 0.05).

CONCLUSIONAPRIL siRNA may significantly suppress the growth and promote apoptosis in transplanted tumor of human colorectal cancer in nude mice. APRIL may become a candidate gene of gene therapy of human colorectal cancer.

Objective To explore the clinical characteristics of pancreatic gland damage in children with Henoch-Sch(o)nlein purpura(HSP).Methods The serum and urine analysis of 95 examples were detected by the automatic biochemical analyzer,which were diagnosed as HSP from Aug.2009 to Jun.2010 in Department of Nephrology,Hunan Children's Hospital,and the clinical characteristics of them were analyzed.All children were treated with anti-infection and anti-allergic drugs.The pancreatic morphology of patients was observed by B ultrasonic,and the clinical features of skin,joints,digestive tract,and kidney damage were observed.And the relationship between damage of pancreas and damage of other systems was analyzed.Results There were 64 cases suffering from pancreatic gland damage in 95 HSP children:34 cases were male(53.1％),30 cases were female(46.9％),and there was no significant difference (x2 =0.56,P ＞ 0.05).The incidence of pancreatic gland damage of the patients with allergic purpura combined with abdominalgia was 82.8％ (53 cases),which was obviously higher than that in the patients without abdominalgia (11 cases,17.2％)(x2 =14.24,P ＜0.05).The incidence of pancreatic gland damage in mixed type of allergic purpura(61 cases,95.3％) was obviously higher than that in the patients which only possess the skin rash(3 cases,4.7％) (x2 =18.18,P ＜0.05).The pancreatic glands of the total 64 patients were detected by type B ultrasonic.None of them had been detected with pancreatic gland edema and deformation of structure.The mean hospital stay of the HSP patients with pancreatic gland damage was (10.80 ± 6.39) days (5-39 days),while mean hospital stay without pancreatic gland damage was (8.42 ± 3.51) days (4-13 days),and there was no significant difference between them (t =5.68,P ＞ 0.05).Conclusions HSP children usually were accompanied with pancreatic gland damage,and if they get abdominalgia and multi-system damage they are more likely to be accompanied with pancreatic gland damage,which should be paid attention to.

Objective To analyze the clinical and pathological characteristics of children in different stages and to investigate the clinical significance based on clinical diagnosis and staging criteria of acute kidney injury(AKI).Methods Based on the clinical diagnosis and staging criteria of AKI,165 AKI children admitted to the Department of Nephrology of Hunan Children's Hospital,between Oct.2004 and Oct.2011 were divided into 3 groups:stage 1,stage 2 and stage 3.Clinical characteristics,age,etiology,pathology and prognosis were compared among 3 groups of children with AKI.Results (1) A total of 165 patients(109 males and 56 females) were included in this study,average age of (6.26 ± 4.43) years,including 69 patients in stage 1,19 patients in stage 2,and 77 patients in stage 3.(2) The 3 groups of patients had an average age of(9.09 ± 3.69) years,(4.34 ± 3.90) years,and (4.22 ± 3.78) years,respectively,which showed significant differences (P ＜ 0.01).(3)Three most frequent causes of AKI were drugs (24.8％),acute glomerulonephritis (AGN) (22.4％) and septicemia (15.2 ％),which showed significant differences (P ＜ 0.01).(4) Renal histopathological examination was performed on 140 AKI children,3 most main types of pathology were acute tubular interstitial nephritis 56 cases (40.0％),endocapillary proliferative glomerulonephritis 33 cases (23.6％) and mesangial proliferative glomerulonephritis 18 cases(12.9％).In the stage 1 patients,glomerular disease was predominant(84.4％).In the stage 2 patients,glomerular disease(38.5％) and tubulointerstitial lesions(38.5％) were the major pathological types.In the stage 3 patients,tubulointerstitial damage (73.0％) was the major pathological type (P ＜0.01).The patients in 3 different groups showed significant differences in the ratio of tubulointerstitial disease and glomerular disease(P ＜0.01).(5)The median recovery time of serum creatinine to the baseline was 9 days(3-41 days) for stage 1 patients,11 days(3-25 days) for stage 2 patients,and 16 days(3-∝ days) for stage 3 patients,which showed a significant difference (P ＜ 0.05).(6)Of the 165 A KI patients,124 cases had hematuria,126 cases had varying degrees of proteinuria.There were significant differences in the hematuria incidence and the duration among the 3 groups(P ＜ 0.01).There was no difference in the proteinuria incidence among the 3 groups (P ＞ 0.05),while the stage 1 patients showed significant differences from the other 2 groups (P ＜ 0.01).Conclusions The patients are mostly seen in stage 1 and stage 3.The stage 1 AKI children are largely school-age children and acute glomerulone phritis is the main etiology.The stage 3 AKI children are mainly infants and the etiology of AKI is mainly drugs and septicemia,the pathological type is mainly acute tubulointerstitial nephritis,and the renal functional recovery is slow.

OBJECTIVETo examine HIV prevalence and its associated factors among men who have sex with men (MSM) and provide the evidence for the intervention program among MSM.

METHODSA face-to-face questionnaire interview was conducted among MSM recruited by snowball sampling method in Yuzhong, Jiulongpo and Shapingba district of Chongqing from July to September, 2007. Totally, 1044 MSM were recruited. Associated factors with HIV prevalence were analyzed using forward stepwise logistic regression that HIV status was the dependent variable and demographics, AIDS awareness, sexual behaviors and the status of the intervention were independent variables.

RESULTSA total of 1044 MSM were surveyed. The rate of AIDS awareness was 89.5% among MSM. The rate of unprotected anal sex during the past 6 months was 63.8%. The prevalence of HIV and syphilis was 8.5% (89/1044) and 12.5% (131/1044) respectively. The multivariate analysis identified that the older MSM (OR = 1.69, 95% CI: 1.13 - 2.52), junior school education (OR = 1.89, 95% CI: 1.17 - 3.05), younger than 18 years old of the first sex (OR = 3.11, 95% CI: 1.20 - 8.02), more than 10 sexual partners (OR = 2.24, 95% CI: 1.24 - 4.02), the history of having sex with women (OR = 2.40, 95% CI: 1.64 - 3.51) and syphilis infection (OR = 4.52, 95% CI: 2.77 - 7.38) were independent risk factors associated with HIV infection.

CONCLUSIONThe rate of unprotected anal sex was high, so were the prevalence of HIV and syphilis among MSM. It should be urgent to conduct the intervention to stop AIDS rapid transmission among MSM.
