OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

Objective:To compare the effectiveness of fire needle versus Western medicine in the treatment of herpes zoster. Methods:Randomized controlled trials comparing fire needle with Western medicine in the treatment of herpes zoster were identified using 8 databases. A meta-analysis was performed using RevMan 5.3 software. Results:Eight trials involving 569 patients were included in this meta-analysis, and the results showed that fire needle was superior to Western medicine comparing the effective rate [risk ratio (RR)=1.13, 95％ confidence interval (CI): 1.06 to 1.20;P=0.0002], the visual analog scale (VAS) score [mean difference(MD)=–7.95, 95％ CI: –10.71 to –5.20;P<0.00001], time of pain disappearance (MD=–7.61, 95％CI: –9.38 to –5.84;P<0.00001), time of blister-stop (MD=–1.34, 95％CI: –1.51 to –1.18;P<0.00001), time of crusted scab (MD=–2.92, 95％CI: –3.62 to –2.23;P<0.00001), and time of scab off (MD=–4.64, 95％CI: –5.83 to –3.46;P<0.00001). In addition, a significantly lower incidence of postherpetic neuralgia was found in the fire needle group in 30 d (RR=0.23, 95％CI: 0.11 to 0.51;P=0.0002) and 60 d (RR=0.33, 95％CI: 0.12 to 0.91; P=0.03) after treatment. Conclusion:Fire needle has a favorable effect in increasing the effective rate, relieving pain, recovering skin lesions and decreasing incidence of postherpetic neuralgia in the treatment of herpes zoster. However, considering the limitations in this study, the findings should be interpreted cautiously.

Objective To study the spatial distribution characteristics of liver cancer in Guangxi so as to provide evidence for the development of congol and prevention on liver cancer.Methods The average eight year morbidity was computed,using the rates of liver cancer in 2000-2007.The spatial statistics module of GIS was used to conduct spatial autocorrelation analysis.and the disease mapping Was drawn,using the Map Info 8.0 software.Results The average morbidity rate Was clustered in Guangxi in the past eight years.with Moran's I index as 0.34 and P value below 0.01.G index appeared to be 0.77 and the Pvalue Was below 0.01.Moran's I correlogram lifled up in four spaces,specifically,the cluster took place in both nlacro-scale(one to three spatial intervals,45 to 135 km real Scale)and micro-scale(16 to 18 spatial intervals,720 to 800 km real scale).When the spatial interval became 14 and real scale was 60 km.the spatial distribution of liver cancer showed the most intensive autocorrelation.Most of the regions with high morbidity would be clustered in the southwest and southern parts,along the Coastal areas of Guangxi while the regions with low morbidity clustered in the northern part of Guangxi.Conclusion Liver cancer was found un-randorely distributed and geographitally clustered in Guangxi in 2000-2007.

Objective:To understand the molecular pat hophysiology of hepatocellular carcinoma and pancreatic cancer.Methods: We studied novel gene expression by cDNA microarray method. The PCR pro ducts of 4 096 genes and 12 800 gene were spotted onto a kind of chemical-mater ial-coated-glass slide in array. Both the mRNAs from 5 cases of hepatocellular carcinoma and 3 cases of pancreatic cancer were reversely transcribed to cDNAs with the incorporation of fluorescent-labeled dUTP to prepare the hybridization probes. After hybridization, BioDoor4096 and BioDoor12800 cDNA microarray were scanned for the fluorescent intensity. Tumor invasion-related gene expression w as screened through the analysis of difference in gene expression profile.Results:Among 4 096 and 12 800 target genes, there were 15 genes who se expression level differed from normal and carcinoma tissues. Therefore, they might be associated with metastasis.Conclusion:Further analysis of these differentially expressed metastasis-associated genes will be helpful for understanding the molecular mechanism of malignant carcinoma.

BACKGROUNDHereditary spastic paraplegia (HSP) is a group of inherited neurodegenerative disorders with the shared characteristics of slowly progressive spasticity and weakness of the lower limbs. Thirteen loci for autosomal dominant HSP have been mapped.

METHODSA Chinese family with HSP was found in the Shandong province and Inner Mongolia Autonomous Region of China and genomic DNA of all 19 family members was isolated. After exclusion of known autosomal dominant loci, a genome wide scan and linkage analysis were performed.

RESULTSThe known autosomal dominant loci of SPG3A, SPG4, SPG6, SPG8, SPG9, SPG10, SPG12, SPG13, SPG17, SPG19, SPG29, SPG31 and SPG33 were excluded by linkage analysis. The results of a genome wide scan demonstrated candidate linkage to a locus on chromosome 11p14.1-p11.2, over an 18.88 cM interval between markers D11S1324 and D11S1933. A maximal, two point LOD score of 2.36 for marker D11S935 at a recombination fraction (theta) of 0 and a multipoint LOD score of 2.36 for markers D11S1776, D11S1751, D11S1392, D11S4203, D11S935, D11S4083, and D11S4148 at theta=0, suggest linkage to this locus.

CONCLUSIONThe HSP neuropathy in this family may represent a novel genetic entity, which will facilitate discovery of this causative gene.

OBJECTIVETo assess the expression of Hsp72 and Hsp73 in chronic obstructive pulmonary disease (COPD) and to evaluate their roles in damage from coal dust exposure.

METHODSA case control study of 50 coal miners suffering from COPD and 50 healthy coal miners were selected from one coal mine. The levels of Hsp72 and Hsp73 in peripheral blood lymphocytes were determined by flow cytometry for all subjects.

RESULTS(1) The expression of basic Hsp72 of peripheral blood lymphocytes for patients and controls was not different from that inducible expressed Hsp72 by 42 degrees C heat stress or by BPDE exposure. (2) The expression of Hsp72 in COPD patients (17.7 +/- 4.9) was significantly lower than that in healthy coal miners (22.6 +/- 10.0) (P < 0.01). On the other hand, the expression of Hsp73 in COPD patients (33.5 +/- 11.7) was higher than that in healthy coal miners (19.6 +/- 5.9) (P < 0.01). (3) A-positive relationship between the expression of Hsp72 and cumulative inhaling coal dust exposure was observed. No relationship was found between Hsp73 and cumulative inhaling coal dust exposure.

CONCLUSIONThe decreased expressions of Hsp72 in peripheral blood lymphocytes of COPD coal miners.

OBJECTIVE To investigate the therapeutic effect of scutellarin on colitis-associated cancer (CAC) and its underlying mechanism based on Wnt/β-catenin signaling pathway. METHODS The mouse model of CAC was estab?lished by azomethane oxide (AOM) and sodium dextran sulfate (DSS), followed by scutellarin treatment, with recording the body weight, diarrhea and hematochezia. After sacrificing the mice, the colorectal length and colorectal tumor were assessed. The levels of pro-inflammatory factors TNF-α and IL-6 in mice's sera were measured by the enzyme-linked immunosorbent assay (ELISA). The colorectal lesions were appraised by hematoxylin and eosin (H&E) staining. Theβ-catenin level in CAC tissues was probed by immunofluorescent analysis. The apoptosis-related genes Bax and Bcl-2, and Wnt signaling pathway-related genes β-catenin, GSK-3β, TCF4, c-Myc and cyclin D1 were detected by real-time quantitative RT-PCR (RT-qPCR). Finally, Western blotting analysis (WB) was employed to examine the expressions of the apoptosis and Wnt signaling pathway-related proteins. RESULTS Scutellarin significantly improved AOM/DSS-caused weight loss, colorectal length shortening, and tumor growth in mice (P<0.01). Meanwhile, colorectal lesions could be substantially alleviated by scutellarin. ELISA results showed that the levels of pro-inflammatory factors TNF-αand IL-6 were drastically lessened (P<0.01). Scutellarin also sharply inhibited the nuclear translocation of β-catenin, as evidenced by the reduction in the nuclear level ofβ-catenin protein. In addition, scutellarin attenuated the mRNA expres?sion of Wnt signaling pathway-relatedβ-catenin, TCF4, c-Myc and cyclin D1, whereas it heightened GSK-3βmRNA level. These results were consolidated by WB analysis, which indicated that scutellarin could mitigate the protein levels of phospho-GSK-3β,β-catenin, TCF4, c-Myc and cyclin D1, with the increase in GSK-3β protein in CAC tissue. Moreover, scutellarin could induce the apoptosis of CAC, demonstrated by enhanced expression of Bax and diminished expression of Bcl-2 in both mRNA and protein levels. CONCLUSION Scutellarin may ameliorate colitis-associated colorectal cancer by weakening Wnt/β-catenin signaling cascade.

The vegetative state is a complex condition with unclear mechanisms and limited diagnostic, prognostic, and therapeutic methods. In this study, we aimed to explore the proteomic profile of tears from patients in a traumatic vegetative state and identify potential diagnostic markers using tears-a body fluid that can be collected non-invasively. Using iTRAQ quantitative proteomic technology, in the discovery phase, tear samples collected from 16 patients in a traumatic vegetative state and 16 normal individuals were analyzed. Among 1080 identified tear proteins, 57 were upregulated and 15 were downregulated in the patients compared to the controls. Bioinformatics analysis revealed that the differentially-expressed proteins were mainly involved in the wound response and immune response signaling pathways. Furthermore, we verified the levels of 7 differentially-expressed proteins in tears from 50 traumatic vegetative state patients and 50 normal controls (including the samples used in the discovery phase) using ELISA. The results showed that this 7-protein panel had a high discrimination ability for traumatic vegetative state (area under the curve = 0.999). In summary, the altered tear proteomic profile identified in this study provides a basis for potential tear protein markers for diagnosis and prognosis of the traumatic vegetative state and also provides novel insights into the mechanisms of traumatic vegetative state.
