ObjectiveTo study the anatomical characteristics of the renal pedicle and its clinical application during retroperitoneoscopic nephrectomy.MethodsThe imaging, surgical video and clinical data of 278 cases undergoing retroperitoneoscopic nephrectomy between July 2007 and September 2009 were retrospectively analyzed. The renal pedicle was found located at the psoas and the medial arcuate ligament of the diaphragm for anatomic landmark before the gap of the psoas. A statistical analysis of the mean operative time, the mean time to look for the renal pedicle, the mean intraoperative estimated blood loss, the mean time to ambulation, the mean time to resuming oral intake, the mean postoperative hospital stay day and the rate of complications was performed.ResultsAll the operations were performed successfully, with no conversion to open and blood transfusion. The mean time to find the renal pedicle was (3.5 ± 1.3 ) min, the mean operative time was (95.6 ±23.8) min, the mean estimated blood loss was (72.4 ±27.5) ml, the mean time to resuming oral intake was (2.1 ±0.7) d, the mean time to ambulation was (1.8 ±0.9) d, the mean postoperative hospital stay was (8.5 ± 2.7 ) d.ConclusionsDuring retroperitoneoscopic nephrectomy, the best anatomical space to look for the renal pedicle is the space before the psoas muscle. The exact location of the renal pedicle is under the diaphragm medial arcuate ligament about 2 - 4 cm, in the gap of the psoas muscle and the vena cava (abdominal aorta). Following this procedure could reduce the time to look for the renal pedicle, thus reducing operative time.

BACKGROUND: Autologous bone marrow is the only tissue that contains abundant osteoinductive osteogenitor cells and is the first-choice transplantation materials for treatment of bone nonunion. Artificial bone with osteoinductive capacity can provide a supporting effect for the in-growth of osteocytes. Iliac periosteum can be used for treatment of bone nonunion due to the advantages including abundant blood circulation, easy harvesting, and able to improve local arterial blood supply. BJECTIVE: To treat refractory bone nonunion in limbs using artificial bone with autologous bone marrow combined with iliac periosteum transplantation, and to compare the therapeutic efficacy to artificial bone with autologous bone marrow transplantation and simple iliac periosterum transplantation. METHOD: Thirty-nine refractory bone nonunion limbs from 36 patients were assigned to three groups: artificial bone with autologous bone marrow combined with iliac periosteum transplantation (combination group, n = 19), artificial bone with autologous bone marrow (bone marrow group, n = 9), and autologous iliac periosteum (iliac periosteum group, n = 11). The time for bone healing, limb function score 1 month after fixture removal, and postoperative X-ray score were evaluated. RESULTS AND CONCLUSION: All initial 39 limbs acquired bone union and were followed up for an average period of 18.5 months. The combination group yielded better therapeutic effects than the bone marrow group and the iliac periosteum group in terms of the time for bone healing, limb function score 1 month after fixture removal, and postoperative X-ray score (P < 0.05). These findings indicate that artificial bone with autologous bone marrow combined with iliac periosteum transplantation exhibits better clinical therapeutic effects in treatment of refractory bone nonunion in limbs.

Objective To investigate the current prevalent status of endemic fluorosis in the alluvial plain area of the Yellow River in Shandong Province,in order to provide a scientific basis for developing control measures against the disease.Methods Six counties were selected as survey counties by random sampling,ten improvedwater projects were selected in each survey county,for the projects,the operating effect was investigated and water fluoride content was tested;three epidemic villages were chosen as survey villages in each county,the operating condition and the fluoride level of water were investigated in the villages with water improvement projects.Dental fluorosis of children aged 8 to 12 was surveyed,the urinary fluoride and skeletal fluorosis X-ray diagnosis were checked of adults over the age of 25.Water fluoride and urinary fluoride contents were detected via the F-ion selective electrode method,and the prevalence of dental fluorosis of all children aged 8 to 12 was diagnosed based on Clinical Diagnostic Criteria of Dental Fluorosis (WS/T 208-2011),skeletal fluorosis X-ray diagnosis was done based on the National Standard for Diagnosis of Endemic Skeletal Fluorosis (WS 192-2008).Results ①In the six counties,58 improved-water defluoridation projects were investigated,all projects were operated normally,the qualified rate of water fluoride content was 44.83％ (26/58).②A total of 19 villages that had water-improving and defluoridation projects were investigated,and all projects were operated normally,the qualified rate of water fluoride content was 42.11％ (8/19).③The overall rate of dental fluorosis among children aged 8 to 12 years old was 49.28％ (480/974),with the index of dental fluorosis as 1.01 in 19 villages,the prevalence of dental fluorosis was mild.In the qualified villages of water fluoride concentration,the positive rate of dental fluomsis among children aged 8 to 12 was 33.41％ (148/443),dental fluorosis index was 0.65,and the prevalence of dental fluorosis was extremely low;in the exceeding-standard villages of water fluoride content,the positive rate of dental fluorosis among children aged 8 to 12 was 62.52％ (332/531),dental fluorosis index was 1.36,and the prevalence of dental fluorosis was mild;the detection rate of dental fluorosis among children aged 8 to 12 of the villages with qualified fluoride content was lower than the rate of the villages with excessive fluoride (x2 =81.91,P ＜ 0.01).④X-ray detection rate of skeletal fluorosis in adults over the age of 25 was 6.14％ (53/863) in 17 villages,there was no statistically significant difference between the qualified villages and the exceeding-standard villages of water fluoride concentration (x2 =1.55,P ＞ 0.05),X-ray detection rate of skeletal fluorosis in adults was 5.04％ (20/397) and 7.08％ (33/466),respectively.In the qualified villages and the exceeding-standard villages of water fluoride,urinary fluoride geometric average and the exceeding rate of urinary fluoride were 1.50 mg/L,44.16％ (170/385) and 2.09 mg/L,62.58％ (286/466),respectively.In the qualified villages of water fluoride,the exceeding rate of adult urinary fluoride was lower than that in the exceeding-standard villages (x2 =28.58,P ＜ 0.01).Conclusions The prevention and control measures on endemic fluorosis have had some effects in the alluvial plain area of the Yellow River in Shandong Province.But the water fluoride content of water improving defluoridation projects still exceeds the national standard seriously,and endemic fluorosis has not been effectively controlled.Prevention measures should be further strengthened.

Objective To evaluate the incidence of asymptomatic carotid stenosis (ACS) in patients with peripheral arterial occlusive disease (PAOD) who was admitted for revascularization.Methods 229 PAOD patients were evaluated by carotid ultrasound preoperatively and divided into severe ACS group (ACS ≥ 70％) and non severe ACS group (ACS ＜ 70％).The clinical characteristics and associated risk factors of the two groups were analyzed.Results The incidence of severe ACS was 19.7％,age,blood pressure,total cholesterol and fibrinogen levels in severe ACS group were significantly higher than those in non-severe ACS group (P ＜ 0.05),the more severe the symptoms of PAOD are,the higher is the incidence of severe ACS.Age,hypertension and hypercholesterolemia were all predictors of severe ACS.Conclusions The severity of PAOD is positively correlated with the incidence of severe ACS.Age,hypertension and hypercholesterolemia are independent risk factors for severe ACS.

Objective To analyze the epidemiologic features of visceral leishmaniasis in different age groups in China from 2005 to 2012,and to provide a scientific basis for prevention and treatment of the disease.Methods The visceral leishmaniasis cases were obtained from China disease epidemic monitoring information system from 2005 to 2012.All the cases were divided into subgroups by demographic characteristics:infant (＜1 year old),childcare (≥1 and ＜4 years old),child (≥4 and ＜15 years old),adult (≥15 and ＜65 years old) and senior adult (above 65 years old).The epidemiologic features,such as gender,season of disease onset and area distribution of visceral leishmaniasis were analyzed.Results The total reported visceral leishmaniasis from 2005 to 2012 were 2 979,among which cases in infant,childcare,child,adult and senior adult were 24.9％,21.7％,20.0％,32.4％ and 1.0％,respectively.Infant cases were most reported in April; childcare cases in December which began to increase since September; child cases in October and adult and senior adult in March.The reported cases were mainly from Xinjiang,Gansu and Sichuan areas.However,age characteristics differed among regions,which were mainly infants,both childcare and children,and adults,respectively in this three areas.The duration from onset to diagnosis was shortest in infant group (11 d) and longer in adult group (15 d).Conclusions The number of visceral leishmaniasis cases in different age groups peaks in different months.Regional distribution is not even.Cases are most concentrated in Xinjiang,Gansu and Sichuan areas.Infants predominate in Xinjiang,childcare and children in Gansu and adults in Sichuan.

Objective To explore the structure of Chinese personality based on natural language and to develop a Chinese personality vocabulary data bank.Methods Based on the sub-factors of Chinese personality scale(QZPS),Chinese personality assessment inventory 2(CPAI-2) and Chinese personality five factors inventory (CPFFI),a self-reported personality questionnaire with 116 items was developed.An exploratory factory analysis and parallel analysis were made to the data collected from 1455 Chinese participants.Results A Chinese Personality Seven Factors Inventory (CPSFI) was developed,which included seven factors with 52 items.51.63％ of the total variance of the seven factors was explained and the internal reliability coefficient was 0.800,while the internal reliability coefficients among the factors were between 0.663-0.912.The retest reliability coefficients of the factors were between 0.700-0.874 (P ＜ 0.01).Conclusions Outgoing and emotion are the core contents of the crossculture personalities.Most of the factors in QZPS,CPAI-2 and CPFFI can be found in the seven factors structure,of which the structure is clearer.
