Objective:To sum up the characteristics of cerebrospinal fluid and brain CT findings of viral encephalitis in children, and provide guidance for clinical diagnosis and treatment of viral encephalitis.Methods: 117 cases of viral encephalitis were selected in our hospital and the results were analyzed by statistical analysis of cerebrospinal fluid and CT in children with viral encephalitis in order to compare the results of cerebrospinal fluid examination and CT examination.Results:Cerebrospinal fluid examination showed that the increased intracranial pressure were 52.14%(61/117), protein>0.5 g/L are 36.75%(43/117), elevated white blood cell levels were 57.26%(67/117), the neutrophils increased 33.33% (39/117), lymphocytes increased 31.62%(37/117), and the sugar concentration <3.3 mol/L are 14.53% (17/117). Head CT in the diagnosis of abnormalities in children were 98 cases, in which 21 were mild abnormal, 57 were moderately abnormal and 20 cases were severe abnormalities. Abnormal cerebrospinal fluid diagnosis rate of 94.02% was significantly higher than the rate of CT abnormalities 83.76% and the difference was statistically significant (x2=6.231,P<0.05).Conclusion: The abnormal rates of CT examination in the diagnosis of viral encephalitis were higher in patients with viral encephalitis. The combination of the two examinations could be more comprehensive than that of the patients with the disease and focus. It could be benefit for clinical treatment.

Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.

We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non-glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate "Damaohua" and "Jizhuahua". The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.

Through the investigation of Phellodendron Cortex on the market, and 28 batches of samples were collected. By using spectrophotometer the color values of outer surface, inner surface and cross - section of these samples were measured. These measured color data was translated into 3D structure diagram by using the Lab color space tool. The level difference value, the mean value and the threshold value were calculated based the measured color data of these different batches of samples. All 28 groups measured data was analyzed using the methods of Ward linkage and average Euclidean distance. At the same time, we invited Professor Jin Shiyuan, the "Chinese medicine master", to identify, quality-evaluate and grade these 28 batches of Phellodendron Cortex samples base on the traditional experience, then compared the traditional empirical results with the spectrophotometer measurement results. The result showed that, the Phellodendron Cortex could be divided into Phellodendri Amurensis Cortex and Phellodendri Chinensis Cortex by color numerical clustering, and classified according to quality. The classification result has a high degree of consistency with the traditional experience.

Objective To determine the plasma concentration of cytarabine(Ara-C) in children with leukemia and obtain dynamics parameters, and investigate the relationship between the parameters and clinical effect in order to provide the basis for optimization of Ara-C application. Methods Using highperformance liquid chromatogram (HPLC) to determine the plasma concentration of Ara-C, its metabolite Ara-U and infusion rate in 37 children with acute leukemia, their therapeutic reaction, remission, treatment-related infection, side-effect and long-term treatment effect were analyzed in statistic. Results Ara-C by 1～2 g/m2 intravenous drop infusion for 2 hours, the peak plasma concentration time was 2 h and peak concentration were (14.37-84.44)μmol/L, and the median was (41.42±22.80)μmol/L. The median infusion rate was 869.57at 30 minutes after Ara-C drip completion, its average level was (253.40±81.49) μmol/L, over six-times than Ara-C peak concentration. The median continuous complete remission time in 37 children was 29.8 months (5.0～53.1 months), 3y-DFS was (90.63±5.15)%. The therapy-related infection rate was 56.8 %(21/37),including three children (8.1 %) suffered from severe infection, but there was no therapy-related death and no children were off the protocol due to poor tolerance. Conclusion As post-remission treatment, high-dose Ara-C would not cause cumulation in vivo in children with acute leukemia and side-effect were slight. Ara-C could improve the long-term continuous complete remission rate and clinical cure rate for children with leukemia. Therefore, it was worth to apply in clinical.

BACKGROUND:Elderly patients have more loose bone. After fractures, bones are mostly crushed. Simultaneously, many elderly patients experience many internal diseases. Various organs have dysfunction. Surgery tolerance is poor, which also brings difficulty in treatment with internal fixator, and increases the risk of therapy. Thus, the choice of internal fixation method is not uniform. OBJECTIVE: To compare and analyze the repair effects of proximal femoral nail anti-rotation blade and anatomic proximal femoral locking plate in treatment of unstable intertrochanteric fractures in the elderly. METHODS:A total of 100 elderly patients with unstable intertrochanteric fractures were selected from the Youyi Branch, Kunshan First People’s Hospital from April 2011 to June 2013. They were randomly assigned to two groups. Patients in the experimental group received internal fixation with proximal femoral nail anti-rotation blade. Patients in the control group received anatomic proximal femoral locking plate. After treatment, folow-up was conducted. Operative indexes, postoperative Harris score for hip function and incidence of complications were compared and analyzed in both groups. RESULTS AND CONCLUSION: No significant difference in various indexes was detected in both groups (P > 0.05). Harris scores were significantly better in the experimental group than in the control group (P < 0.05). Postoperative complications were significantly less in the experimental group than in the control group (P < 0.05). These results indicated that internal fixation of proximal femoral nail anti-rotation blade for unstable intertrochanteric fractures in the elderly achieved satisfactory results in the recovery of joint function and had the advantage of few complications.
