There were 50 normal children in control group The urine routine, the ?2-microglobulin (?2 -M), mosmol and THP in urine and blood, the AIb, rGT and NAG in urine, the renal function and serum concentration of amikacin were determined respectively.The 43 patients with serious illness childten in study group, were divided into 2 groups (Group 1 and group 2 ). Group 1 (23 cases) was treated only with amikacin for 7 days, and group 2 (20 cases) was treated with vitaminC, vitamin E and amikacin for 7 days. Before treatment, the 3rd and 7th day during the treatment, all the items mentioncd above were examined in gtoup 1 and 2.Results The incidences of nephrotoxic injury of amikacin are 87 per cent (20/23)and 55 per cent (11/20) respectively in group 1 and 2. There is significant difference (P

Objective:To differentiate hepatitis B virus (HBV) infection from hepatitis C virus (HCV) infection among different indolent B-cell non-Hodgkin lymphoma (B-NHL) subtypes. The correlation between indolent B-NHL and hepatitis viral infection was also investi-gated. Methods:A total of 733 indolent B-NHL patients from January 1994 to January 2014 with integrated clinical information were retrospectively investigated. We compared the hepatitis viral infection between the general population and indolent B-NHL patients. We analyzed the infection rate of hepatitis virus in the different indolent B-NHL subtypes and examined their correlations. Results:The HBs-Ag positive rate of the indolent B-NHL was 7.9%, which was not significantly different with that of the general population (7.9%vs. 7.2%, P=0.548). Among the different indolent B-NHL subtypes, the 48 splenic marginal zone lymphoma (SMZL) patients exhibited the highest HBs-Ag positive rate, which was significantly higher than those of the general population (18.8%vs. 7.2%, P=0.002), other indo-lent B-NHL subtypes (18.8%vs. 7.2%, P=0.004), and other marginal zone B-cell lymphoma (MZL) patients (18.8%vs. 7.1%, P=0.005). The HBs-Ag positive rates between other B-NHL subtypes and the general population were not significantly different. The coexpression of HBs-Ag, HBe-Ag, and anti-HBc-Ab exhibited no significant difference among the various B-NHL subtypes. However, the co-expres-sion of HBs-Ag, HBe-Ab, and anti-HBc-Ab was significantly higher in the SMZL group than the other B-NHL subtypes (16.7%vs. 4.7%, P<0.001).The positive rate of the anti-hepatitis C virus antibody (HCV-Ab) was 1.9%in 733 indolent B-NHL patients, which was significant-ly higher than in the general population (1.9%vs. 0.4%, P<0.001). The HCV-Ab positive rates in the chronic lymphocytic leukemia, lym-phoplasmacytic lymphoma/Waldenstr?m macroglobulinemia, SMZL, hairy cell leukemia, nodal marginal zone B-cell lymphoma group were 2.2%, 2.5%, 4.2%, 3%, and 3.7%, respectively. These values were significantly higher than those of the general population. Preva-lence rates of HCV in B-cell lymphoproliferative disorders, unclassified, extranodal marginal zone B-cell lymphoma of mucosa-associat-ed tissue lymphoma, B-cell prolymphocytic leukemia, and follicular lymphoma groups were not significantly different compared with the general population. Conclusion:Prevalence rate of HBV was higher in the SMZL group than other indolent B-NHL groups, which suggests that HBV infection may play an etiologic role in SMZL.

OBJECTIVETo determine the factors affecting post-operative velopharyngeal function of cleft palate patients aged over two years old.

METHODSThe data on 245 patients, including first visit case records and those in the database, were searched and recorded. Post-operative velopharyngeal function and clinical features, such as cleft ratio, adequate ratio, diagnosis, operative age and method, were analyzed retrospectively.

RESULTSCleft ratio and adequate ratio in the velopharyngeal competence (VPC) group were not statistically different from those in the velopharyngeal incompetence (VPI) group. The difference in VPC rate in different age groups and diagnosis was not significant. The post-operative VPC rates under different methods were significantly different.

CONCLUSIONThe current therapeutic schedule for patients younger than two years old is inappropriate for patients older than two years old. Cleft ratio is not the main factor affecting postoperative velopharygeal function. Sommerlad-Levator Veli Palatini reconstructional operation combined with sphincter pharyngoplasty can obviously improve the velopharyngeal function of patients aged 2 years old and up. This method should be applied in primary palatoplasty.

Objective To investigate the clinical and laboratory characteristics of patients with chronic lymphocytic leukemia (CLL). Methods 503 patients with CLL admitted from October 1998 to February 2015 were retrospectively analyzed. Baseline characteristics were compared using Chi-square test and Kaplan-Meier methodology was undertaken for survival analyses. Results The median age was 58 years (26-86 years):335 cases were male and 168 cases were female. 204 cases (40.5%) were at the clinical stage of Binet A, followed by Binet B (148 cases, 30.1%) and Binet C (151 cases, 29.3%). 108 cases (21.1%) had anemia at diagnosis, while 113 cases (26.5 %) had an elevated level of lactate dehydrogenase and the expression of CD38 was detected among 100 cases (29.1 %). Clonal abnormalities were observed using fluorescence in situ hybridization (FISH) analysis. Those involving 13q deletion were the most frequent (156 cases, 47.3 %), followed by IgH translocation (22.4 %), trisomy 12 (21.2 %) and 17p deletion (14.5 %). The mutational status of immunoglobulin heavy chain variable region was determined among 230 cases, 165 cases (71.7%) of which were found to be with mutated status. The most frequently encountered gene was V4-34 (28 cases, 12.4 %). The median progression-free survival (PFS) was 89.0 months (95 %CI 75.0-103.0 months), while the median overall survival was 129.0 months (95 %CI 106.9-151.1 months). Conclusion Compared with patients in the western world, CLL patients in this study are younger at diagnosis and have longer overall survival, which, to some extent, could reflects the characteristics of CLL patients in China.

Objective to explore the current situation and related influencing factors on the retention time of patients receiving methadone maintenance treatment (MMT). Methods Information on basic situation and daily treatment of the patients were collected from the 7 MMT clinics opened in the pro-two batch in Hunan province. Retention rate and influencing factors were analyzed. Results (1) The retention rates after 6 and 12 months of MMT became 72.06% and 49.65% respectively. (2) The retention rates of high-dosage group and low-dosage group were 85.03% and 68.03% after 6 months on MMT program while became 60.48% and 46.28% after 12 months of MMT respectively. (3) The mean retention time of HIV+ patients and HIV- patients were 9.46 months and 8.62 months respectively during the 12 months follow-up observation, showing a significant difference. (4) Patients who took large dose methadone, did not share needles, at older age or HIV+ , were prone to keep MMT at a long period. Conclusion The retention rates for 6 months and 12 months in the MMT program in Hunan province were similar to the national data. Dose, type of drug abuse, age and HIV status were related to the period of retention.
