ObjectiveTo observe the effect of Jidesheng snake medicine on patients with bites by unknown poisonous insects. Methods69 cases with bites by unknown poisonous insects were randomly divided into the experimental group (35 cases)and the control group (34 cases).The experimental group used Jidesheng snake medicine for external application,the control group used povidone iodine.The treatment effect within one week was compared,including cure rate,total effective rate,satisfaction degree of patients and incidence rate of complication. ResultsAfter treatment,the cure rate and total effective rate of the experimental group was 71.43％ and 97.14％,higher than 61.76％ and 85.29％ of the control group.The incidence rate of complications was 2.86％ in the experimental group,lower than 8.82％ of the control group.The satisfaction degree of patients in the experimental group was 91.43％,significantly higher than 85.29％ of the control group. ConclusionsApplication of Jidesheng snake medicine in treatment of bites by unknown poisonous insects is more effective,and the incidence rate of complication was lower.It is worthy of clinical application.

Because of their physiological and anatomical immaturity, premature infants are prone to disorders of glucose metabolism. In the ifrst week after birth, infants have the greater risk of abnormal glucose metabolism. Compared with term infants, the glucose/insulin homeostasis of preterm infants is very different. This article reviewed the characteristics of glycometabolism in premature infant and the methods of glucose test.

Objective To study the time-dependent changes and mechanisms of auditory cortex in prelingual sensorineural hearing loss. Methods Two groups (9-12, 19-22-year-old) of hearing-loss patients and matched normal hearing subjects received MR diffusion and MRS examination. The ROI for ADC measurement were placed on the Heschl gyrus (HG), and for NAA/Cr, Cho/Cr on the superior temporal gyrus(STG). Results There was no statistical difference among groups both in the NAA/Cr and Cho/Cr (P>0.05), Left side NAA/Cr 2.46±0.51, 2.49±0.52, 2.26±0.33;Right side NAA/Cr 2.26±0. 46, 2. 44±0. 45, 2. 27±0. 46. Left side Cho/Cr 0. 88±0. 21,0. 92±0. 18, 0. 87±0. 13 ; Right side Cho/Cr 0. 88 ± 0. 18, 0. 87 ± 0. 22, 0. 81 ± 0. 16. There was statistical difference of ADC value among normal hearing subjects and 9-12, 19-22-year-old hearing-loss patients(F = 4. 42, P < 0. 05, F = 11.37,P<0. 05). There was significant difference of ADC value between normal hearing and 19-22 year-oldhearing-loss (q = - 44. 89, P = 0. 008, q = - 54. 28, P = 0. 027) on both left and right HG, and there wassignificant difference between normal hearing and 9-12 year-old hearing-loss only on right HG (q =- 32. 54, P = 0. 000), Left side (860 ± 103), (885 ± 48), (905±77) mm<'2>/s, Right side (848 ± 73),(880 ± 61), (902 ± 52) mm2/s. Conclusion Compared with the normal hearing, the ADC value increased in 20-year-length of deafness. The NAA/Cr and Cho/Cr of STG showed no changes among the three groups.

Objective To study the effect of using Dexamethasone in different time for treatment and prevention of bronchopulmonary dysplasia (BPD), in order to provide the clinical reference as to whether dexamethasone can be used to prevent and treat BPD.Methods A total of 135 very low birth weight infants hospitalized for 1 week who still survived on mechanical ventilation were studied.The total cases were divided into early Dexamethasone group and none Dexamethasone group.Whether early using dexamethasone could prevent BPD or not were observed.The BPD infants were divided into 3 groups, early Dexamethasone group, later Dexamethasone group and none Dexamethasone group.The effect of using Dexamethasone on BPD in different time were observed.Results (1) Among these 135 infants,there were 65 infants developing BPD.The incidence of BPD was 48.15％.There were no significant differences in the prevalence of BPD, the death rate and the disease index of BPD between the early Dexamethasone group and the none Dexamethasone group (all P ＞ 0.05).(2) There were no significant differences in mechanical ventilation time among the 3 BPD groups [(19.81 ± 5.67) d vs (22.32 ± 6.20) d, (21.46 ± 7.02) d, P =0.405].But the average time of inhaling oxygen and hospital stays of later Dexamethasone BPD group were shorter than early Dexamethasone BPD group and none Dexamethasone BPD group.The differences were significant [(37.27 ± 10.14) d vs (45.96 ± 9.91) d,(43.42 ±8.73) d,P=0.012;(64.11 ±8.14) d vs (76.13 ±7.57) d,(68.59 ±8.53) d,P =0.000].(3) The incidence of infection (90.90％, 100.00％ vs 81.90％), hyperglycemia (27.27 ％, 30.43 ％ vs 10.00 ％), hypertension(9.09％ ,13.04％ vs 0) and neonatal necrotizing enterocolitis(22.73％ ,34.78％ vs 15.00％) of all the infants who received Dexamethasone were higher than the infants who did not receive Dexamethasone.But the differences showed no significance(all P ＞ 0.05).(4) There were no significant differences among the 3 BPD groups in growth [weight : (9.16 ± 1.53) kg vs (8.92 ± 1.13) kg, (9.07 ± 1.46) kg;height: (71.26 ± 8.59) cm vs (69.54 ± 9.32) cm, (70.32 ± 9.07) cm] or been in hospital again because of pulmonary infection during one year(75.00％ vs 65.00％ ,72.22％) (all P ＞ 0.05).The differences of abnormal Chinese children development scale scores among the BPD groups (mental development index ＜ 80:20.00％ vs 15.00％, 16.67 ％;physical development index ＜ 80:25.00％ vs 20.00％, 16.67％) showed no significance(all P ＞ 0.05).Conclusions Early use of Dexamethasone has no effect to prevent BPD.Dexamethasone therapy on BPD should be used in the later stages ,and small doses and short protocol are preferred.

Objective To evaluate the value of MSCT in differentiate cystic lesions in different cervical region. Methods Forty cases with cyst lesions in the neck which was confirmed by pathology were collected in our study. The following diseases were excluded: cystic lesions from thyroid gland and thymus or bronchus, cystic changes of solid lesions ( necrotic lymph node) and cystic or solid lesions in the parotid gland. All patients underwent MSCT scan on GE Lightspeed 16. The parameters were following: 120 kV,260 mA, thickness 5 mm, pitch 1. 375. The delay time for contrast enhanced CT was 25 seconds for arterial phase and 60 seconds for vein phase. Results Lesions were analyzed in 4 different cervical regions including parotid gland, midline, lateral cervix and posterior cervix. Among the lesions in parotid area,2 were first brachial cyst and the other 2 were epidermoid cyst. First brachial cyst occurred intraparotid gland and epidermoid cyst occurred intraparotid or extraparotid gland. Among the lesions in midline area, 17 cases were thyroglossal cysts,81.0% were in the level hyoid bone, 12 cases of thyroglossal cysts protruded at the preepiglottic space or oral base. Another kind of lesions in midline included 3 cases of epiglottic cysts and 1 epidermoid cyst in the lower level of the neck which involved infrasternal level. The 12 cases of second brachial cysts occurred in the lateral neck. Ten cases were in the left side. Type Ⅱ was the most common type and account for 5 cases among all of second brachial cysts. Type Ⅰ and type Ⅱ were running up,accounting 3 cases respectively. Type Ⅳ account for 1 case. Two cases with lymphangioma and 1 case with third brachial cyst located at the posterior neck. Conclusion According to the location and typical imaging appearance, MSCT can do the differentiation of different cystic lesions in the different area of neck.

Objective To study the MRI features of sporadic Creutzfeldt-Jakob disease(sCJD). Methods Three patients with clinically diagnosed sCJD underwent MR study,including SE T_1WI,FSE T_2 WI,and DWI sequences.The MR imaging features were analyzed.Results The lesions were not definite either in SE T_1 WI or in FSE T_2 WI,but were prominent in DWI.Abnormal hyperintensive signal appeared in the cerebral cortex,with the frontal,parietal,and occipital lobes being the mostly involved region.The subcortical white matter was normal.The bilateral caudate nuclei and thalami could also be involved.The abnormal signal could be either symmetrical or asymmetrical.There was diffuse atrophy of the brain parenchyma in the late phase of disease,especially in the cortex.Conclusion With the application of MR study,especially the DWI,combined with its characteristic clinical manifestation,the diagnosis of sCJD can be made definitely.

Objective To define the characteristic values of the pharyngeal cavity by comparing the values of measures and ratios between the patients with obstructive sheep apnea-hypopnea syndrome(OSAS) and controls.Methods Sixty-eight OSAS patients who were diagnosed using polysomnography,and 56 healthy people were scanned by MSCT(multiple slices computed tomography)in the awake state.Then, the values were measured on the reformated images and were compared between two groups.Results Of the 63 values,49 values were different between the two groups,and among those,4 values were entered into the Discriminant Functions.These were the left-right diameter(LR)[OSAS:LR=(9.4?3.7)mm,controls: LR=(20.1?5.0)mm,t=-13.820,P=0.000)and the cross-sectional area(XSA)[OSAS:XSA= (54?27)mm~2,controls:XSA=(164?77)mm~2,t=-10.944,P=0.000]of RP,the heights of tongue [OSAS:(75.4?8.3)mm,controls:(58.4?9.8)mm,t=10.476,P=0.000],the lengths of uvula/the lengths of airway(OSAS:0.139?0.039,controls:0.154?0.048,t=-1.983,P=0.050).Conclusions Many measures and ratios were different between the two groups,but there were overlaps between them. Measures using the Discriminant Functions can help the diagnosis of OSAS.
