Objective: To observe the clinical effects of comprehensive treatmenton cutaneous region for low back pain.
Methods: One hundred and twenty outpatients with low back pain who met the diagnostic criteria were randomly divided into a cutaneous region group or a medication group, 60 cases in each group. The cases in the cutaneous region group were treated by Nie-pinching up the skin of the lumbosacral region, cupping and acupuncture. Those in the medication group were treated by oral administration of Celecoxib capsule. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess the therapeutic effects.
Results: After treatment, the VAS scores of both groups were different from those before treatment, showing statistical significances (allP<0.01). The D-valuse of VAS scores of both groups were different from those before treatment, showing statistical significances (allP<0.01). The D-value of OID scores in the cutaneous region group was significantly different from that in the medication group(P<0.01). After treatment, the total effective rate was 91.7% in the cutaneous region group versus 76.7% in the medication group, there was a significant difference in comparing the clinical effect (P<0.01).
Conclusion: Both comprehensive treatment on the cutaneous region and Celecoxib capsule can obviously relieve low back pain. But comprehensive treatment on the cutaneous region is better than Celecoxib capsule in the therapeutic effects.

Objective To study the prevalence and progression of non-motor symptoms (NMS) during 2 years follow-up in idiopathic PD patients,and to investigate the relationship of NMS with quality of life and motor symptoms.Methods A total of 82 idiopathic PD patients were involved in the survey.Unified Parkinson's Disease Rating Scale (UPDRS) and Non-Motor Symptoms Questionnaire for Parkinson's disease (NMSQuest) and Mini Mental State Examination (MMSE) were used to assess non-motor symptoms.Results The NMS total scores were higher at the end of follow-up than at baseline [(11.97±5.54) vs.(9.45±5.13),r=0.620,P=0.007].The scores of 6 symptoms including daytime salivation,constipation,photism or auditory hallucination,depression,sleep walking or somniloquy,diplopia,and 4 syndromes including digestive system,hallucination and delusion,cardiovascular system and other system were significantly increased.The symptoms of hallucination and delusion,and the decrease of recent memory at baseline had significant correlations with the decline of quality of life and the aggravation of motor symptoms (r=0.625,0.578,P=0.016,0.035).Conclusions NMS present in the whole course of PD and show rapid changes.NMS have correlations with the decline of quality of life and the aggravation of motor symptoms.

Objective To explore the effect of DNA methylation inhibitor 5-aza-2'-deoxycytidine (5-Aza-CdR) on proliferation and tumor suppressor gene PRDM1α expression in Burkitt's lymphoma cell line NAMALWA. Methods MTT was used to study the impact of DNA methylation inhibitor on proliferation in NAMALWA cells,and comparative real-time reverse transcription-polymerase chain reaction (RQ-PCR) with SYBR Green assay was used to detect PRDM1α gene expression. Results MTT results showed that 5-AzaCdR inhibited proliferation of NAMALWA cells in a dose-dependent manner.After treated with 5-Aza-CdR for 72 h at 0.01,0.0625,0.1,0.125,0.25,0.5,1,2 and 4 μmol/L,the inhibition rates were 21.93 ％,39.23 ％,47.69 ％,50.37 ％,53.54 ％,57.72 ％,62.31％,65.68 ％,67.87 ％,respectively,and the differences of absorbance among the groups were also statistically significant (all P＜ 0.01). Meanwhile, 5-Aza-CdR could induce the re-expression of PRDM1α, and △Ct of 0.5, 1, 2 μmol/L groups showed significant differences compared with control group (all P ＜ 0.05). Conclusion DNA methylation inhibitor 5-Aza-CdR can significantly inhibit the proliferation of Burkitt' s lymphoma cell line NAM ALWA,and the possible mechanism of this inhibition may be induction of demethylation and re-expression of PRDM 1α.

18F fluorodeoxyglucose, as a kind of tracer, has its limitations in positron emission tomography/computed tomography (PET/CT). 18F-fluorothymidine (18F-FLT) is a kind of new tracer. The value of 18F-FLT in diagnosis of tumor, tumor staging and assessment of therapeutic effects was reviewed in this article.

Objective To analyze the clinical effectiveness,safety and significance of treatment with external circular fixator,through the relationship of inducible nitric oxide synthase (iNOS) and bone regeneration to further explore the mechanism of the molecular biology of bone lengthening at the same time.Methods Collected bone defect after tibial shaft fractures secondary infection who were treated with external circular fixator as study group (28 cases),all the cases fixed by external circular fixator,20 healthy volunteers as control group.Study group in different time point measured the levels of serum iNOS content,were compared with the control group.Results All patients were scheduled to reach the extremity lengthening and the bone defect were repaired and healed in study group.The bacterial culture results showed that 18 cases (64.29％,18/28) of resistant Staphylococcus aureus,5 cases (17.86％,5/28) of Hemolytic streptocaccus,2 cases (7.14％,2/28) ofP.aeruginosa,one case (3.57％,1/28) of drug-resistant Enterobacter cloacae,one case(3.57％,1/28) of Staphylococcus epidermidis,one case(3.57％,1/28) of Onion-like aeromonas,the proportion of the former two was significantly higher than other bacteria (P ＜ 0.05).The levels of serum iNOS content 1 d after surgery in study group were increased,compared with control group,difference was no significant (P ＞ 0.05).The levels of serum iNOS content 14 d after surgery,stoped extend,1 d stoped extend,3 d stoped extend in study group were significantly higher than those in control group [(118.8 ± 6.6) U/L vs.(86.4 ± 5.4) U/L,(136.2 ± 8.4) U/L vs.(88.2 ± 3.6) U/L,(132.6 ± 9.0) U/L vs.(87.6 ± 4.8) U/L,(103.8 ± 5.4) U/L vs.(86.4 ± 4.2) U/L] (P ＜ 0.05),there was no significant difference between two groups in other times (P ＞ 0.05).Conclusions External circular fixator for the repair and reconstruction effects in patients with bone defect can achieve the desired therapeutic goal,the higher expression of iNOS may be one of the molecular biological mechanisms of bone lengthening.

Objective:To explore the clinical significance detecting adrenomedullin (ADM)and high sensitive C reac-tive protein (hsCRP)in patients with acute coronary syndrome (ACS).Methods:A total of 51 inpatients,which were eliminated for coronary heart disease (CHD)by coronary angiography (CAG),were enrolled as non CHD group,and 124 ACS patients diagnosed by CAG were regarded as ACS group.ADM and hsCRP concentrations were measured before and after CAG in non CHD group and before and after percutaneous coronary intervention (PCI) in ACS group,and they were compared between two groups.Results:Before CAG/PCI,compared with non CHD group,ADM [(28.7±1.6)pg/ml vs.(36.7±2.5)pg/ml]and hsCRP [(4.74±3.21)mg/L vs.(27.65±11.76) mg/L]levels significantly rose in ACS group,P<0.05 or <0.01.Compared with before PCI,there were signifi-cant increase in levels of ADM [(36.7±2.5)pg/ml vs.(47.1±5.3)pg/ml]and hsCRP [(27.65±11.76)mg/L vs.(39.53±4.83)mg/L]in ACS group after PCI,P<0.01 both,and significantly higher than those of non CHD group (P<0.05~<0.01).There were no significant difference in ADM and hsCRP levels in non CHD group be-tween before and after CAG (P>0.05 all).Conclusion:Detecting arenomedullin combined high sensitive C-reac-tive protein is gelpful to early diagnosis and evaluating lesion severity for acute coronary syndrome.
