In clinical teaching practice of over 30 years, professor LIAN Yu-lin combines physiological, pathological and anatomic knowledge with TCM treatment based on syndrome differentiation, forming own unique theoretical system. This paper introduces LIAN's experience on treatment of cervical spondylosis in detail, and location of cervical vertebra three lines and determination of needling depth and reinforcing-reducing manipulation based on clinical manifestations of various types of cervical spondylosis, and combination of long needle with short needle, deep needling with superficially needling, stressing the main point and having a definite object. This is an effective pathway for treatment of cervical spondylosis.

OBJECTIVE: To evaluate the short-term efficacy and investigate the factors of specific immunotherapy (SIT) efficacy of allergic rhinitis. METHOD: Fifty-seven patients with allergic rhinitis to dermatophagoides pteronysinus were included to receive SIT. Pair t-test was used to compare the symptom scores, visual analogue scores (VAS) and medication scores in patients before SIT and into maintain treatment statement to evaluate the clinical efficacy. T-test and Spearman correlation analysis were used to analyze the correlation between gender, age,reaction condition of skin prick test (SPT) and serum sIgE and the efficacy of SIT. RESULT: SIT was able to significantly reduce the symptom scores, VAS and medication scores. But the correlation between gender, age, SPT, and sIgE and theefficacy of SIT were not significant. CONCLUSION SIT is effective in the short-term treatment of AR. Further research is needed to investigate the factors that impact the efficacy of SIT.

AIM: To investigate the effect of VEGF gene transfer on matrix metalloproteinases(MMPs) and tissue inhibitor of metalloproteinases(TIMPs) expression after vascular balloon injury. METHODS: 90 New Zealand white rabbits were divided into 3 groups randomly: group Ⅰ(balloon injury group), groupⅡ (pAdtrackCMV group) and group Ⅲ(pAdtrackCMV-VEGF165 group). Hypercholesterol diet was given for 7 days before experiment and continued to receive until the animals were killed. Each group were divided into five subgroups according to the sacrifice time. Blood samples and iliac arteries were harvested for further analysis. RESULTS: In group Ⅰ and Ⅱ, MMP2 and TIMP1,2 expressions were detected during the whole process ,while in group III ,MMP1,2,9 and TIMP1,2 could be detected from 3 days after gene transfer and reached the highest level at 1 week and could not be detected at 8 week. CONCLUSIONS: Imbalance expression of MMPs and TIMPs occurred after vascular injury and this may be the reason of pathological remodeling. Local phAdtrackCMV-VEGF165 transfer could specifically change the expression of MMPs and facilitate the positive remodeling process after vascular injury.

Objective To use the matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) technique for detecting the mutation gene of neonatal non-syndromic hereditary hearing impairment gene in Guangxi and to investigate its effectiveness and feasibility in clinical application.Methods A total of 7 100 newborns were performed the hearing preliminary screening and secondary screening by adopting AABR.The genomic DNA was extracted by the heel blood spot.Twenty mutation characteristics of 4 deaf predisposing genes were detected by MALDI-TOF-MS.Results The pass rate of hearing screening in 7 100 newborns was 97.11％ (6 895/7 100),the positive rate of neonatal gene mutation was 3.54％ (251/7 100),in which the GJB2 gene mutation was in 131 cases,the carrying rate was 1.84％,235delC heterozygous mutation was in 108 cases.SLC26A4 gene mutation was in 93 cases,which dominated by 1229C＞T heterozygous mutation and IVS7-2A＞G heterozygous mutation,mtDNA12SRNA gene mutation was in 16 cases and GJB3 gene mutation was in 11 cases.Conclusion Adopting the MALDI-TOF-MS screening technique can increase the detection rate of hot point mutation in common deaf related genes and discover neonatal genetic NSHI from molecular level and provides the corresponding geneticconsulting guidance for early finding and predicting deaf occurrence,and formulating the interventional measures.

The influence of inner cell mass (ICM) and trophectoderm (TE) score on pregnancy outcomes in frozen-thawed blastocyst transfer cycles was analyzed. A retrospective analysis of 741 cycles of frozen-thawed blastosysts transfer was performed. All cycles were divided into four groups based on the number and morphological score of blastocysts: S-ICM B/TE B group (n=91), the single blastocyst transfer of ICM B and TE B; D-ICM B/TE B group (n=579), double blastocysts transfer of ICM B/TE B; D-ICM B/TE C group (n=35), double blastocysts transfer of ICM B/TE C; and D-ICM C/TE B group (n=36), double blastocysts transfer of TE B/ICM C. The pregnancy outcomes were compared among the four groups. As compared with D-ICM B/TE C group, the clinical pregnancy rate, implantation rate and multiple pregnancy rate were increased in D-ICM B/TE B group (74.96% vs. 57.14%, 57.43% vs. 37.14%, and 48.62% vs. 25%, respectively, P<0.05 for all). Clinical pregnancy rate and implantation rate in D-ICM B/TE B group were also higher than in D-ICM C/TE B group (74.96% vs. 50%, and 57.43% vs. 33.33%, both P<0.05). Multivariable Logistic regression analysis indicated that ICM score was a better predictive parameter for clinical pregnancy (OR=3.05, CI 1.70-5.46, P<0.001), while the trophectoderm score was a better one for early abortion (OR=0.074, CI 0.03-0.19, P<0.001). Clinical pregnancy rate and multiple pregnancy rate in S-ICM B/TE B group were significantly lower than those in D-ICM B/TE B group (46.15% vs. 74.96%, and 2.38% vs. 48.62%, both P<0.05), but there was no significant difference in the implantation rate between the two groups. It was suggested that the higher score of ICM and TE may be indicative of the better pregnancy outcomes. The ICM score is a better predictor of clinical pregnancy than TE, while TE score is a better one in predicting early abortion. Single ICM B/TE B blastocyst transfer in frozen-thawed cycles can also get satisfactory pregnancy outcomes.

AIM: To investigate the status of myopia in students from different kinds of schools in Shantou city, China.
METHODS: In this cross-sectional study, 2 418 students from 4 middle and high schools in Shantou were surveyed through randomized cluster sampling. Ophthalmic examination and auto-refraction were performed for all subjects.
RESULTS: Among all 2 394 students examined. The myopia rates for students from middle and high school were 48. 07% and 68. 28%. In normal middle school, students from rural area had lower rate of myopia than students from the urban area (χ2 = 13. 879, P<0. 01 ). Students from key rural high schools had lower rate of myopia than students from key urban high school (χ2 =175. 231, P<0. 01).
CONCLUSION:The prevalence of myopia in the middle school of urban area in Shantou was higher than rural area. The increasing rate of myopia in youngsters is correlated with study stress. In order to decrease the myopia rate, it is extremely important to improve study environment in students.

Objective To evaluate clinical efficacy of retroperitoneal laparoscopic adrenalectomy in patients with adrenal disease.Methods 21 cases of adrenal disease undergoing retroperitoneal laparoscopic adrenalectomy from Jun.2006 to Oct.2010 were retrospectively reviewed.Results All operations were performed successfully except 2 cases were converted to open surgery due to peritoneal rupture,which resulted in difficult exposure of retroperitoneal cavity.The operation time ranged from 55 to 300 minutes,with 90 minutes as the medium.Blood loss volume ranged from 10 to 100 ml during operation (30 ml as the medium ).No blood transfusion was given.No complication such as massive hemorrhage,infection,abdominal visceral injury etc.occurred.19 patients were treated successfully and followed up from 3 to 55 months with 12.3 months as the medium.No tumor recurrence and metastasis was found in the 19 cases.Conclusion Retroperitoneal laparoscopic adrenalectomy has advantages of high safety,less complications and satisfactory efficacy in patients with adrenal diseases.
