The experimental acute spinal cord injury (SCI) was performed in 10 rabbits at L_1 level using the method of compredssing the abdominal lateral of spinal cord. The rabbits were treated with naloxone (2mg/kg/h) intravenously 45 minutes after SCI and treated continually for 4 hours. In the control group, equal volume of saline was administered. The ascending and descending conductive function of spinal cord was measured by mortor evoked potential (MEP) and cortical somatosensory evoked potential (CSEP). The result showed that amplitude of the MEP and CSEP peaks came to a normal level 2 hours after SCI and were significantly higher (P

Objective:To observe effects of Cuttle-Bone on blood inorganic phosphorus and parathyroid hormone(PTH)in patients of uremia in hemodialysis.Methods:74 cases of uremia in hemodialysis were randomly divided into a control group,a cuttlefish bone treatment group and a calcium carbonate treatment group.The control group did not take any conjugation agent of phosphorus. The cuttlefish bone treatment group were treated with oral administration of cuttlefish bone powder 3.0g in each meal and the calcium carbonate treatment group with chewing calcium carbonate tablets 1.5g in each meal.They all were treated for 3 months. Results:After treatment,blood inorganic phosphorus and PTH decreased(P0.05),with less effect on blood calcium(P

Objective To study the prevalence of peripheral arterial disease(PAD).Methods Totally 2668 fishermen and their families above 35 years old were recruited in a cross sectional study of randomly cluster sampling in 10 villages of Zhoushan fishery area,one of the biggest four fishery in the world,in Summer.All the cases underwent the ankle arm index(AAI) measurement using portable doppler ultrasound device.An AAI less than or equal to 0.9 was considered to be indicative of significant PAD.Fasting plasma glocose and oral glucose tolerance test(OGTT)were also examined to distinguish normal glucose tolerance(NGT),imparied glucose tolerance(IGT)and diabetes melitus(DM). Results The prevalence of PAD of 2668 cases was 2.1%.PAD prevalence was found to be 2.1%,2.9%,and 6.3% in patients with NGT,IGT,and DM respectively.It was seldom seen in people under 50 years old and the PAD was more popular in older people.Conclusions The prevalence of peripheral arterial discase of the general people in Zhoushan fishery area is lower.

Objective To improve the recognition of abnormal image of soft tissue in cheeks. Methods Images of 47 cases with abnormal soft tissue in cheeks were retrospectively studied. Results (1) 15 cases were originated from soft tissue of the cheeks in which 8 cases were benign and 7 cases were malignant.6 cases were invaded by maxillofacial affection nearby,in which 1 case was benign and 5 cases were malignant.26 cases were involved by lesions of jaw bones,including benign tumor of jaw bones in 9, malignant tumor of jaw bones in 14 and chronic osteomyelitis of jaw bones in 3 and all had bony destruction; (2) According to originated position,21 cases were not originated from jaw bones,in which there were 5 cases (23.8%) with destruction of jaw bones;(3)In the 26 cases with abnormal soft tissue of cheeks originated from jaw bones, 9 were benign tumors in which all the soft tissue masses were mainly localized inside of the jaw bones, while 14 cases were malignant tumors in which all the soft-tissue masses were localized both inside and outside of the jaw bones. There was remarkable difference between the two groups(P=0.000).All 9 cases of benign tumors appeared as dilated destruction of jaw bones, while in the 14 cases of malignant tumors, 12 cases showed osteolytic bone destruction and the other 2 cases showed ossific bone destruction,there was significant difference between the two groups(P=0.000).Conclusion CT and MRI are of significance in judging original position, extent and differential diagnosis between benign and malignant lesions of abnormal soft tissue in cheeks.

Objective To explore the function of auditory efferent system in the subjects with tinnitus.Methods Effects of contralateral stimulation on otoacoustic emission in 24 subjects with tinnitus were measured for analysis the function of the medial olivo-cochlea system. Results ①The incidence of SOAE 41.7% in 24 normal ears,and 37.5%,20%,33.3% in different groups of tinnitus and the amplitude were suppressed. ②The suppressive amplitude of TEOAE was 2.1?0.8 dB SPL in 24 normal ears and 1.9?0.8 dB SPL in 16 ears with tinnitus, but there was no suppression in 8 ears with tinnitus. ③There were observable suppression in 3 ears, but 2 ears had no contralateral suppression in tinnitus with normal hearing group. 8 ears showed suppression in tinnitus with hearing loss, 2 ears had no changes. 4 ears had no contralateral suppression in tinnitus subjects with low frequency hearing loss.Conclusion The effects of suppression in the normal ears of subjects with tinnitus is as normal subjects, but those different results of suppression in the tinnitus ears indicate that mechanism of tinnitus is multiformity.

Objective To investigate the BUN content and ALT activity in cataract at serum and Lens by Fuming tablets.Methods The BUN content in serum and cens of the model group,treatment and control groups was detected by Urease-Berthelot method,while ALT activity in serum and Lens of the model,freatment and control group was delected by Laishi method.Results The BUN contemtin lens of treatment group Ⅰ and Ⅱ was lower than that in control and molel group(P

Objective To explore the relationship between the post-thoracotomic wound infection and nutritional status.Methods The patients treated with thoracotomy were divided into the simple wound infection group(n=15) as the experimental group and the phase Ⅰ healed group (n=15) as the control group.On the fifth day after operation, the sero-albumin quantity and cumulative nitrogen balance were recorded respectively. The statistical data were given the test.Results Every average index of sero-albumin in the experimental group was lower than the control group. Among them, the total protein comparison had statistical significance (P0 05) and transferrin comparison had statistical difference (P

Objective To explore the transmission route of Legionella pneumophila in central air-conditioning system. Methods The environmental samples collected from four public places of Nanjing city were detected by nested-PCR and analyzed by phylogenetic analysis. Results The positive rate of Legionella pneumophila in sediment, cooling water, aerosol near cooling tower, dust in duct surface and indoor air were 100%(9/9),78.6% (11/14),25.4% (17/67),16.7% (2/12) and 17.3% (13/75), respectively. The nucleotide sequence similarities of Legionella pneumophila in cooling water and indoor air was more than 92%. Conclusion The main pollution source of Legionella pneumophila is cooling water and Legionella pneumophila can be transmitted to indoor air through central airconditioning system.

Objective To inverstigate the effect and safety of refractory intrahepatic and extrahepatic bile duct stones treated by choledochoscope holmium laser combined with electrohydraulic lithotripsy.Methods The cllnical data of 67 cases of postoperative intrahepatic and extrahepatic bile duct stones treated with combined endoscopic holmium laser and electrohydraulic lithotripsy were analysed retrospectively.Results After 1 to 7 times of biliary endoscopic holmium laser electrohydraulic lithotripsy treatment,65 patients had complete removal of all residual stones with the success rate of 97%,and without complications.Conclusions After holmium laser combined with electrohydraulic lithotripsy,the effect of choledochoscopic removal of intrahepatic and extrahepatic bile duct residual stones can be greatly improved It is a safe method for treatment of refractory intra-and extra-hepatic bile duct stones.

Objective To report clinical and laboratory features of a rare case who was primary myelofibrosis (PMF) with positive JAK2 V617F terminating in T-acute lymphoblastic leukemia (T-ALL).Methods A rare case of PMF terminating in ALL was found, the quantity and quality of JAK2 gene mutation were defined by PCR methods, collected the clinical dates. Results The JAK2 V617F gene mutations were all positive pre and post-blast, the mutant rates respectively were 71.21% and 83.56 %. The interval from PMF to leukemia was 22 months, and from leukemia to death was 27 days. Conclusion PMF with positive JAK2 V617F terminating in ALL is a rare case, clinical prognosis is poor and survival time is short.
