Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P<0.05), and the sleep durations were significantly extended (P<0.05); in comparing the improvement of anxiety, Neiguan plus Zusanli group > Neiguan group >Zusanli group (P<0.05); in comparing the improvement of sleep, Neiguan plus Zusanli group was superior to both Zusanli group and Neiguan group (P<0.05), while there was no significant difference between Zusanli group and Neiguan group (P>0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.

Objective To investigate the prognostic value of CD 4+CD25+/high CD127 low/-and CD14+HLA-DRlow/-for evaluating the severity of acute pancreatitis .Methods The percentages of CD4+CD25+/highCD127low/-and CD14+HLA-DRlow/-and the CD64 index were measured by flow cytometry in pa-tients with acute pancreatitis ( including 43 cases of mild acute pancreatitis and 24 cases of severe acute pan-creatitis).Moreover, the levels of C-reactive protein (CRP), acute physiology and chronic health evaluationⅡ( APACHEⅡ) score and CT severity index ( CTSI ) were detected for a correlation analysis .Results The percentages of CD4+CD25+/highCD127low/-and CD14+HLA-DRlow/-and the CD64 index in patients with severe and mild acute pancreatitis were significantly higher than those in healthy subjects .Patients with se-vere acute pancreatitis showed higher percentages of CD 14+HLA-DRlow/-than patients with mild acute pan-creatitis.With the disease progression, the CD64 index and the levels of CD4+CD25+/highCD127low/-, CD14+HLA-DRlow/-and CRP were significantly dropped after an initial increase in patients with mild acute pancrea -titis, while these indexes were continuously elevated in patients with severe acute pancreatitis .The percent-age of CD14+HLA-DRlow/-was positively correlated with CD64 index, CRP level, APACHEⅡ score and CTSI.Conclusion CD14+HLA-DRlow/-level was closely related to the severity of acute pancreatitis , which could be used as immune parameter for the estimation of the clinical severity of acute pancreatitis .

Objective:To evaluate the clinical outcomes of implant-retained overdentures.Methods:57 patients treated by implant-retained overdentures were included.Parameters for peri-implant tissue conditions (e.g.peri-implant probing depth,plaque index,bleeding on probing,mucosal hyperplasia,peri-implant marginal bone loss) and prosthetic complications were examined and recorded.The precentage of satisfaction of the patients was assessed using the visual analog scale (VAS).Results:After an average follow-up of (48±11.3) months,the survival rate of the implants was 98.1%,the marginal bone loss was (1.38±0.74) mm.There was no statistically difference among the different attachment groups(bar,magnet and ball) regarding the peri-implant marginal bone loss or bleeding on probing(P>0.05).The peri-implant probing depth and plaque index in patients with magnet and ball attachments were lower than those in patients with bar attachments(P<0.05).The major complications were the upper abutment fracture,prostheses fracture and screw loosening.Most patients were satisfied with their prostheses and there was no statistically significant difference between the attachment types(P>0.05),except that magnet and ball attachments were much easier to clean compared with bar attachments(P<0.05).Conclusion:Implant-retained overdenture is a successful and satisfactory treatment option for patients with edentulous jaw.The patients should been given regular clinical examinations to keep peri-implant tissue health and reduce the complications,especially those with bar attachments.

Objective To study dynamic expression of Oct-4 during development of colorectal cancer (CRC) and investigate the association between Oct-4 expression and prognosis of patients with CRC.Methods CRC tissues, matched non-tumor tissues and colonic polyp tissues were collected and Oct-4 expressions were analyzed by quantitative reverse transcription-polymerase chain reaction (qRT-PCR), flow cytometry analysis (FCM) and immunohistochemistry (IHC).Medical records of patients with CRC were reviewed.Clinicopathological analysis was performed to assess the association between Oct-4 expression and certain chnicopathological parameters.Kaplane-Meier survival curve was conducted to evaluate association between Oct-4 expression and survival time of patients with CRC.Results The results of qRT-PCR showed that the relative expressions of Oct-4 mRNA in matched non-tumor, colonic polyp and CRC tissues were (0.23 ±0.16) × 10-5, (1.19 ± 0.76) × 10-5 and (3.79 ± 1.94) × 10-5 respectively, with a significant difference (F =8.633, P =0.001).IHC analysis displayed that the positive expression ratios of Oct-4 in matched non-tumor tissues, colonic polyp tissues and CRC tissues were 4.43％, 12.68％ and 40.51％ respectively, and a significant difference was discovered among them (x2 =66.311, P ＜ 0.001).Oct-4 expre-ssion in CRC was significantly correlated with pathological stage (x2 =7.248, P =0.007), lymph node metastasis (x2 =4.888, P =0.027), distant metastasis (x2 =5.732, P=0.017) and TNM stage (x2 =4.174, P=0.041).Kaplan-Meier survival curve analysis demonstrated that Oct-4 positive cases had a shorter median survival time (37.0 months) compared with Oct-4 negative cases (76.0 months), with a significant difference (x2 =14.050, P =0.001).Conclusion The expression of Oct-4 is step-wise increased during development of CRC.The abnormal expression of Oct-4 may play certain roles in the development of CRC.Oct-4 may be an important biomarker for the clinical diagnosis, assessment of disease and prognosis in CRC.

Graphene ( GN) and multiwalled carbon nanotubes ( MWCNT) composites were coated on glassy carbon electrode ( GCE ) and then poly ( nicotinic acid ) ( PNA ) was electrodeposited on the modified electrode. The electrochemical behavior of pyridoxine hydrochloride ( VB6 ) was investigated at the modified electrode by cyclic voltammetry ( CV ) and differential pulse voltammetry ( DPV ) . Results showed the oxidation current of VB6 at the GN-MWCNT/PNA/GCE was obviously larger than that at GCE, PNA/GCE and GN/MWCNT/GCE. The oxidation process of VB6 was an irreversible diffusion-controlled process involving one electron and two protons. The liner range between the peak current intensity of DPV and the concentration of VB6 was 0 . 05-200 μmol/L with a detection limit of 0 . 02 μmol/L ( S/N=3 ) . The modified electrode showed a good reproducibility with a relative standard deviation of 3 . 1% ( n=8 ) . The proposed method was applied to the analysis of vitamin B6 in vitamin B6 tablets and compound vitamin B tablets with recoveries between 96 . 1%-104 . 5%.
