Objective To summarize the clinical effect of transpedicular Dynesys dynamic fixation for treating degenerative lum-bar disease.Methods 34 cases of degenerative lumbar disease were treated by transpedicular Dynesys dynamic fixation and per-formed the retrospective analysis.The VAS score of lumbago was (6.01±0.98),the VAS score of skelalgia was (5.47±0.63), ODI was(64.47 ±2.06)%.The cranial intervertebral space height in the fixed segment was(12.01±1.08)mm,the intervertebral space height in the fixed segment was(11.47±1.13)mm;the caudal intervertebral space height in the fixed segment was(11.95± 1.06)mm;the intervertebral motion range of the cranial segment in the fixed segment was(8.11±1.21)°,the intervertebral motion range of the fixed segment was(8.47±1.63)°,the intervertebral motion range of the caudal segment in the fixed segment(7.86± 1.36)°.39 intervertebral spaces in 27 cases adopted the decompression combined with Dynesys fixation,the single intervertebral space in 7 cases was performed with Dynesys fixation alone.Results All patients smoothly pulled through the perioperative period. No complications of wound infection,leakage of cerebralspinal fluid and nerve inj ury occurred,wound infection,leakage of cerebro-spinal fluid and nerve injury.All patients were followed up for 25-45 months,averaged 31.2 months.The VAS score of lumbago at the last time of follow up was (1.85±1.03),the VAS score of skelalgia was(1.54±0.18),ODI was(11.42±1.51)%,the cranial intervertebral space height in the fixed segment was(11.85±0.93)mm,the intervertebral space height of the fixed segment was (11.34±1.02)mm,the caudal intervertebral space height in the fixed segment was(11.62±0.97)mm;the intervertebral space motion range of the cranial segment in the fixed segment was(8.85 ± 1.33)°,the intervertebral space motion range of thye fixed segment was(4.54±1.78)°,the intervertebral space motion range of the caudal segment in the fixed segment was(7.62±1.21)°. Conclusion Transpedicular Dynesys dynamic fixation for treating degenerative lumbar disease can confine and reserve the motion range of the fixed segment,lessen lumbago and skelalgia,improve the function of waist and leg and have no obvious influence on the adjacent segment,its short-term therapeutic effect is satisfactory,but long-term therapeutic effect needs the clinical observation of long time and large amount cases.

Objective To assess the application of contrast-enhanced ultrasound (CEUS) in evaluation of the renal cortical and medullary perfusion changes before and after acute renal failure (ARF) in rabbits. Methods Rabbit ARF models were established with intramuscular 50% glycerin (12-15 ml/kg) injection into rabbits' thighs. One day before and after ARF models establishment, CEUS was performed on each rabbit. The renal perfusion time-intensity curve (TIC) was analyzed, including parameters like AT (arrival time), TTP (time to peak intensity), A (amplitude of peak intensity), AUC (area under the curve), β (slope rate of TIC) of renal cortex and medulla. Results The value of A and β before model establishment was (17.36±13.73) dB and (5.38±2.08) dB/s, respectively, both was significantly higher than those after glycerin injection ([6.59±4.25] dB and [1.58±1.41] dB/s, respectively) (P<0.05). The value of TTP and AUC before model establishment was (2.46±1.76) s and (329.31±171.70) dBs, both was significantly lower than those after injection ([5.93±4.80] s and [722.28±354.14] dBs, respectively) (P<0.05). No significant difference was found in AT of renal cortex and AT, A, TTP, AUC, β of renal medulla, nor in SCr or BUN. Conclusion CEUS can display the changes of perfusion image of the renal cortex of the ARF earlier than SCr and BUN.

Objective To investigate the current status of coal-burning endemic fluorosis and the fluoride content in foods and drinking water in Hongya County,Sichuan Province.Methods Dental fluorosis and urinary fluoride were suveyed in children of 8～12 years old in two schools which repectively located in Gaomiao and Wawushan Town.The adults above 20 years old underwent clinical examination.At the same time,fifty adults above 20 years old in Garden Village were chosen to take forearm and calf X-ray films to find out the evidence of skeletal fluorosis.The content of fluoride in food such as bacon,corn,dry capsicum in Sanxing Village in Gaomiao Town and Futian Village in Wawushan Town as well as drinking water in five families in Sanxing Village were determined.Results The dental fluorosis rate of children was 40.76%(161/395),the dental fluorosis index was 0.86 in Gaomiao Town.The dental fluorosis rate of children was 14.36%(82/571),the dental fluorosis index was 0.31 in Wawushan Town.The medium value of the urine fluoride was 0.81 mg/L.ranged 0.16～3.89 mg/L.The positive rate oi the clinical examination of skeletal fluorosis was 5.27%(27/512),the X-rays detective rate was 4.00%(2/50).The medium value in bacon,corn,dry capsicum were 6.00,0.64,1.49 mg/kg.The averaged content of the fluoride in drinking water(0.14±0.06)mg/L of local household was within the eligible limitation.Conclusions It is currently a mild endemic disease in Hongya Country,its incidence is reduced apparently,pathogenetic environmental fluoride content is reduced.The main source of fluoride is from the preserved ham contaminated with fluoride,which is epidemiologically significant in endemic area of Hongya County.Defluoriding countermeasures should be taken in the endemic areas.

Objective The study was conducted to investigate the acute phase of convulsion related problem on the clinical manifestations,imaging and electroencephalograph (EEG) examination of purulent meningitis.Methods Cluster sampling method was employed to select children in our hospital,a total of 301 cases with purulent meningitis was analyzed retrospectively.Among them,62 cases had convulsion.The incidence of convulsion in the acute phase of the purulent meningitis,risk factors,and prognosis were analyzed.Results The convulsion incidence rate of acute purulent meningitis was 20.60％.The partial seizure was eight cases (12.90％).The secondarily generalized seizure following partial seizure was 15 cases (24.19％).The generalized seizure was 32 cases (51.61％).The convulsive status was 7 cases (11.29％).The EEG abnormality was significantly different between the convulsion group and the no convulsion group (P ＜ 0.05).The incidence of brain organic damage was significantly different between two groups (P ＜0.05).The multivariate unconditional logistic regression analysis showed,cause of disease,first symptom,disturbance of consciousness,obvious signs,and cerebrospinal fluid culture with convulsion were the relevant factors (P ＜ 0.01).Conclusions The most common seizure of purulent meningitis was the generalized seizure.Brain organic damage easily resulted in convulsion of purulent meningitis.The days of hospitalization,cause of disease,first symptom,disturbance of consciousness,obvious signs,and cerebrospinal fluid culture with convulsion were the positively relevant factors.Those positively relevant factors in combination of the clinical manifestations,imaging,and EEG examination in children would play an important role in diagnosis,treatment,and prognosis evaluation of convulsion derived from purulent meningitis.Moreover,convulsion affects the disease recovery in children with purulent meningitis.
