OBJECTIVETo explore the effects of nano-hydroxyapatite/polyamide 66 (n-HA/PA66) cage on recovering and maintaining lumbar curvature, lumbar heights and fusion rate when used in the transforaminal lumbar interbody fusion.

METHODSFrom February to July 2012, 50 patients with degenerative lumbar disease(lumbar disc herniation in 32 cases and lumbar spondylolisthesis in 18 cases) were treated with transforaminal lumbar interbody fusion using the n-HA/PA66 cage, and their preoperative and postoperative clinical outcomes were analyzed. The patients were followed up for 2, 4, 6 and 8 months after operation, during which the CR and CT film of lumbar vertebra were checked to get relative height of vertebral space, Taillard index,index of lumbar spinal curvature,angle of segmental and full lumbar lordosis. The data were analyzed respectively with pair t-test, analysis of variance or LSD-t-test.

RESULTSAll the patients were followed up, and the duraion ranged from 8 to 13 months, with a mean of 11.32 months. There were significant differences in relative height of vertebral space, Taillard index, index of lumbar spinal curvature, angle of segmental and full lumbar lordosis after surgery, but there were no significant differences in different periods after operation. The fusion time of lumbar ranged from 4 to 8 months.

CONCLUSIONThe n-HA/PA66 cage can recover and maintain lumbar normal stability with higher rate of fusion and less complications.

Alteration in the structural appearance of the optic disk and retinal nerve fiber layer usually precedes the development of reproducible glaucomatous visual field defects.Identification of these changes is important in the diagnosis and treatment of glaucoma at an early to moderate stage and in monitoring its clinical course.This paper reviews the optical coherence tomography(OCT),Heidelberg retina tomography(HRT),optic nerve head stereophotograph(ONHP)and scanning laser polarimetry(SLP) in the field of open angle glaucoma.

Objective: To compare the efficacy difference between moxibustion at sensitized-acupoints and non-sensitized- acupoints using the same group of acupoints. Methods: A total of 139 patients with chronic superficial gastritis were divided into a sensitized acupoint group (102 cases) and a non-sensitized acupoint group (37 cases) based on whether acupoint sensitization occurred. The SPSS version 19.0 statistical software propensity score matching function was used to balance the baseline data between the groups. Finally, 29 pairs of matched patients were included, namely 29 cases in the sensitized acupoint group and 29 cases in the non-sensitized acupoint group. Both groups were treated with moxibustion therapy. The treatment lasted for 30 min per time, and was performed every other day for 8 weeks. Changes in the traditional Chinese medicine (TCM) symptom score and the short-form 36-item health survey (SF-36) score in both groups were observed before and after treatment, as well as the clinical efficacy. Results: The covariates of age, course of disease, TCM symptom score and SF-36 score in the two groups were balanced after matching (all P>0.05). After treatment, the total effective rate was 100.0％ in the sensitized acupoint group and 79.3％ in the non-sensitized acupoint group. The difference in the total effective rate between the two groups was statistically significant (P<0.01). After treatment and at the 4-week follow-up, the TCM symptom scores in the sensitized acupoint group were significantly lower than those in the non-sensitized acupoint group (all P<0.01); the SF-36 scores in the sensitized acupoint group were significantly higher than those in the non-sensitized acupoint group (all P<0.01). Conclusion: With the same group of acupoints, the sensitized acupoints have a better therapeutic effect and long-term efficacy than the non-sensitized acupoints in the treatment of chronic superficial gastritis.

Objective To evaluate the efficacy of chemoradiotherapy alone and prognostic factors for locally advanced rectal cancer. Methods The clinical data of 47 patients with locally advanced rectal cancer who were admitted to our hospital and mostly treated with chemoradiotherapy alone from 2003 to 2010 were retrospectively analyzed. Three of the patients received radiotherapy alone. The Kaplan?Meier method was used to estimate overall survival (OS), progression?free survival (PFS), and distant metastasis?free survival ( DMFS ) rates, and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox regression model was used for multivariate prognostic analysis. Results In all patients, the 3?and 5?year OS rates were 53?2% and 33?2%, respectively, while the 3?and 5?year PFS rates were 37% and 31%, respectively. During the follow?up, 15 patients (32%) had local progression with PFS of 1?60 months (median PFS, 14 months);23 patients (49%) had distant metastasis with DMFS of 2?60 months ( median DMFS, 17 months) . Patients treated with high?dose radiotherapy had significantly lower 3?and 5?year local progression rates than patients treated with medium?dose radiotherapy ( 11% vs. 54%;11%vs. 57%;P=0?004). After chemoradiotherapy, 9 patients (19%) had clinical complete response (cCR), and the 3?and 5?year OS and PFS rates in those patients were all 8/9. The univariate analysis indicated that tumor distance from the anus and cCR were influencing factors for prognosis ( P= 0?026;P= 0?000 ) . However, the multivariate analysis showed that cCR was the only influencing factor for survival ( HR=12?24;95% CI, 1?64 ?91?29;P= 0?015 ) . Conclusions Chemoradiotherpay or radiotherapy alone is effective and safe in the treatment of patients with locally advanced rectal cancer who have to give up surgery or have unresectable tumors. High?dose radiotherapy may improve local control rate. Complete response to chemoradiotherapy predicts satisfactory treatment outcomes.

This study attempts to discuss the correlation between UGT1A1*28 as uridine diphosphate glucuronosyltransferase gene promoter and coding region Gly71Arg gene polymorphism with neonatal hyperbilirubinemia of neonates in Wuhan.A total of 168 neonates were divided into the hyperbilirubinemia group (case group,n=108) and healthy neonates group (control group,n=60).Their DNA was obtained through blood extraction.The gene exon mutation of UGT1A1 was detected by Sanger sequencing,which revealed the relationship between UGT 1A 1*28 and Gly71Arg polymorphism with neonatal hyperbilirubinemia of neonates.The results showed that:(1) The frequency of UGT1Al*28 allele mutation in the case group and the control group was 9.3％ and 10％ respectively,with the difference being not significant between the two groups (P＞0.05).(2) The frequency of Gly71Arg allele mutation in the case group and the control group was 35.1％ and 21.7％ respectively,with the difference being significant between the two groups (P＜0.01).(3) The serum bilirubin level of Gly71Arg mutant homozygous and heterozygous subgroups (n=66) in the case group was 302.7±31.4 μmol/L,which was significantly higher than 267.3±28.5 μmol/L of the wild subgroup (n=42) (P＜0.01).It was suggested that the occurrence of neonatal hyperbilirubinemia of neonates in Wuhan was not associated with UGT 1A1*28 gene polymorphism,but closely with the Gly71Arg gene polymorphism.Meanwhile,the Arg allele mutation was related to the degree of jaundice.
