OBJECTIVETo evaluate the short term effectiveness of lumbar disc herniation by Coflex.

METHODSFrom December 2007 to June 2008, 31 patients (16 males and 15 females) were treated by Coflex. The average age was 51.4 years (range, 33 - 70 years). The average period of follow-up was 10 months. To evaluate the short term effectiveness of lumbar disc herniation by Coflex by JOA, VAS, the conventional radiography and oswestry disability index (ODI).

RESULTSThe average JOA score increased from 9.1 +/- 1.1 preoperatively to 26.4 +/- 1.7 at 6 month postoperatively. ODI decreased from 24.7 +/- 4.8 preoperatively to averaged 4.5 +/- 1.1 at 6 months postoperatively. The VAS score decreased from 7.9 +/- 0.8 to 3.0 +/- 0.9. The clinical symptoms after operation were improved significantly. There were statistically significant differences between the preoperative and postoperative HD (height of dorso- intervertebral discs), DS(distance across the two adjacent spinous processes), DI (distance of intervertebral foramina). The average HD increased from (7.9 +/- 1.1) mm preoperatively to (10.8 +/- 1.3) mm after operation. The average DS increased from (28.3 +/- 2.4) mm preoperatively to (36.4 +/- 1.7) mm postoperatively. The average DI changed from (18.8 +/- 1.0) mm preoperatively to (21.6 +/- 1.7) mm postoperatively. Complications occurred in 3 patients (9.6%). One case complained of persistent low back pain. One case showed opposite lower limb pain in 3 weeks after operation, and was cured after appropriate treatment. One case had the loosening of Coflex in 6 months after surgery, but did not appear related clinical symptoms.

CONCLUSIONCoflex for lumbar disc herniation can increase the HD and DI significantly, and it has positive meaning for keeping height of lumbar vertebral space and treating the nerve root symptom of lumbar disc herniation.

Objective To investigate the change of the basic fibroblast growth factor(bFGF) leve in human detrusor muscle(DM)in bladder outlet obstruction(BOO)due to benign prostatic hyperplasia(BPH)and its implication.Methods Fifty-four patients with BPH were divided into two groups:the obstructive DM stability and instability groups;and 15 men with bladder tumor who underwent operation in the same period were enrolled in the control group.The bFGF mRNA level in DM was measured by reverse transcription and polymerase chain reaction(RT-PCR)and the bFGF protein level was measured by immunohistochemical staining method.Results The bFGF-mRNA expression level of bladder smooth muscle cells was significantly lower in the control group than that in the obstructive DM stability and instability groups(all P＜0.05),but there was no significant difference between the obstructive DM stability and instability groups(P＞0.05). Conclusions The expression level of bFGF mRNA in bladder DM is elevated in BOO due to BPH,but there is little or no correlation between the increased expression of bFGF mRNA and detrusor muscle instability.

This study was aimed to investigate various factors influencing long-term survival in patients with acute promyelocytic leukemia. A single institutional retrospective study with long-term follow-up was performed to better define the prognostic factors and a rationale for the use of ATRA, chemotherapy, and As(2)O(3) in the treatment of newly diagnosed APL patients. Newly diagnosed patients with APL entering complete remission (CR) were followed up for 6 to 185 months (n = 170) from January 1990 to December 2004. Univariate and multivariate analysis of 8 potential factors influencing survival and prognosis were carried out with Log-Rank and Cox regression method, including sex, age, initial WBC count, the level of lactic hydrogenase (LDH), first induction regimen, time from induction therapy to CR, post-remission therapy, negative or positive rate of PML-RAR alpha and follow-up of reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the estimated 5-year overall survival (OS) and relapse-free survival (RFS) were 80.9% +/- 4.0% and 71.0% +/- 4.0% respectively. The 23 patients relapsed at the median time of 15 months (6 - 70) after CR. Univariate analysis revealed that initial WBC count, first induction regimen, time from induction therapy to CR, type of post-remission therapy and persistent negative RT-PCR in remission were important prognostic factors for long-term survival. Multivariate study demonstrated that only type of post-remission therapy was associated with RFS and OS. It is concluded that the post-remission treatment combining ATRA, As(2)O(3) and chemotherapy would significantly improve the long-term survival of APL patients entering CR(1).

The International Standard Chinese-English Basic Nomenclature of Chinese medicine (ISN) was released in 2007, a nomenclature list consisting of 6 500 Chinese medical terms. ISN was the culmination of several years of collaborative diligent work of over 200 specialists who represent Chinese medicine in 68 countries. The overall goal for devising standard English nomenclature for Chinese medicine is to develop a practical international standard nomenclature for Chinese medical basic terms, to make it compatible with contemporary research and educational standards in the globalized health care service. In this article, provided is an overview of principles and methods for the multilingual translations, the processes behind the particular content of the Chinese-English ISN and an introduction to the ongoing new projects, i.e. the multilingual versions of ISN (International Standards of Chinese-Spanish, Chinese-French and Chinese-Portuguese Basic Nomenclature of Chinese Medicine).

Objective:To explore the significance of proactive healthy living index(PHLI)to provide a reference for the elderly to maintain function through healthy daily life.Methods:The functional status of the elderly was defined based on gait speed and cognitive function.Logistic regression model was used to select the daily life indicators which could be the risk factors for the functional status, and a nomogram was graphed for its visualization.PHLI was formed according to the result of the nomogram.Receiver operating characteristic curve(ROC)was plotted according to the functional status of the elderly, and the cut-off value of PHLI was determined based on the principle of the maximum sum of sensitivity and specificity.Results:A total of 4 971 participants with an average age of (70.9±7.5)years were included in the cross-sectional study, of whom 2 649 cases(53.3%)maintained normal function.The Logistic regression analysis showed that the housework had the most significant effect on the functional status of the elderly, followed by positive psychology( OR=2.04, 1.92; both P<0.001), increasing the likelihood of maintaining normal function by 104% and 92%, respectively.Regular life patterns, adequate protein intake, sleep quality and so on also influenced functional status of the elderly(all P<0.05). The PHLI median score of the elderly was 7.3(5.9, 8.3)points.The area under the curve(AUC)was 0.70(95% CI: 0.68-0.71), and the cut off value of PHLI was 6.8 points. Conclusions:The PHLI is associated with the maintenance of functional capacity in the elderly, which can be applied as a simple tool to provide reference for old people to keep functional health through living a proactive healthy daily life.

Objective:To investigate the individual and combined effects of calf circumference and vitamin D levels on all-cause mortality risk in community-dwelling older adults based on the Chinese Longitudinal Healthy Longevity Survey.Methods:The calf circumference was measured in the baseline survey in 2012 and 2014.Low calf circumference was defined as <34 cm for men or 33 cm for women at screening.Vitamin D deficiency was defined as plasma 25-hydroxyvitamin D[25(OH)D]levels <50 nmol/L.All participants were followed up until 2018, when death outcomes and survival time were collected.Cox proportional hazard regression models were used to analyze the effects of calf circumference and 25(OH)D levels on the risk of all-cause mortality.Results:A total of 3 052 older adults were included in the analysis, of which 1 960(64.22%)had low calf circumference and 2 245(73.56%)had vitamin D deficiency.After 10 559.9 person-years of follow-up period, 1 312 death events were recorded.After adjusting for sociodemographic characteristics, physical activities, cognitive function, and multiple chronic diseases, calf circumference and 25(OH)D levels were negatively associated with the risk of all-cause mortality(both P<0.05). In the combined analysis, compared with the normal group, the risk of death was highest in the participants with both low calf circumference and vitamin D deficiency, which was higher than those with low calf circumference or vitamin D deficiency alone, with a hazard ratios( HR)(95% CI)of 2.51(1.81-3.45), 1.71(1.22-2.42)and 1.53(1.09-2.15), respectively.There was a significant additive interaction between low calf circumference and vitamin D deficiency on mortality(RERI>0). Conclusions:Low calf circumference and vitamin D deficiency are associated with higher mortality.Older adults with combined conditions had a even higher risk of death.Attention should be paid to joint screening and comprehensive intervention for older adults with both low calf circumference and vitamin D deficiency.

OBJECTIVES: This study aimed to explore the effects of silencing isoprenylcysteine carboxyl methyltransfe-rase (Icmt) through small interfering RNA (siRNA) interference on the proliferation and apoptosis of tongue squamous cell carcinoma (TSCC). METHODS: Three siRNA were designed and constructed for the Icmt gene sequence and were then transfected into TSCC cells CAL-27 and SCC-4 to silence Icmt expression. The tested cells were divided as follows: RNA interference groups Icmt-siRNA-1, Icmt-siRNA-2, and Icmt-siRNA-3, negative control group, and blank control group. The transfection efficiency of siRNA was detected by the fluorescent group Cy3-labeled siRNA, and the expression of Icmt mRNA was screened by quantitive real-time polymerase chain reaction (qRT-PCR) selected the experimental group for subsequent experiments. The expression of Icmt, RhoA, Cyclin D1, p21, extracellular regulated protein kinases (ERK), and phospho-extracellular regulated protein kinases (p-ERK) were analyzed by Western blot. The proliferation abilities of TSCC cells were determined by cell counting kit-8 assay. The change in apoptosis was detected by AnnexinV-APC/propidium staining (PI) assay. Cell-cycle analysis was conducted by flow cytometry. RESULTS: The expression of Icmt mRNA and protein in TSCC cells significantly decreased after Icmt-siRNA transfection ( CONCLUSIONS Silencing Icmt can effectively downregulate its expression in TSCC cells, reduce the RhoA membrane targeting localization and cell proliferation, and induce apoptosis. Thus, Icmt may be a potential gene therapy target for TSCC.

OBJECTIVES: The effect of isoprenylcysteine carboxymethyltransferase (ICMT) silencing on the migration and invasion of tongue squamous cell carcinoma was investigated by constructing the small interfering RNA (siRNA) of ICMT. METHODS: Through liposomal transfection, siRNA was transfected into human tongue squamous cell carcinoma CAL-27 and SCC-4 cells (ICMT-siRNA group) with a negative control group (transfected with NC-siRNA) and a blank control group (transfected with a transfection reagent but not with siRNA). Quantitative real-time polymerase chain reaction was performed to analyze the mRNA expression of ICMT and RhoA in each group of cells after transfection and to measure the silencing efficiency. Western blot was applied to examine the expression levels of ICMT, total RhoA, membrane RhoA, ROCK1, matrix metalloproteinase (MMP)-2, and MMP-9 proteins in each group. The migration and invasion abilities were evaluated via wound healing and Transwell motility assays. RESULTS: After CAL-27 and SCC-4 cells were transfected with ICMT-siRNA, the expression levels of ICMT genes and proteins decreased significantly in the experimental group compared with those in the negative and blank control groups ( CONCLUSIONS The migration and invasion abilities of CAL-27 and SCC-4 cells were reduced significantly after the transfection of ICMT-siRNA, and the involved mechanism might be related to the RhoA-ROCK signaling pathway.
