Objective To investigate the effects of short-term continuous subcutaneous insulin infusion (CSII) in newly diag-nosed type 2 diabetes mellitus(T2DM ) and to evaluate the treatment regimen conversion after CSII therapy .Methods 72 patients with newly diagnosed T2DM were treated with CSII for 2 weeks .Then they were randomly divided into two groups :the basal insu-lin group(glargine) and the oral anti-diabetic drug(OAD) group .Both groups were followed up for 2 years .Blood glucose ,insulin and HbA1c were measured before and after CSII and during the 2-year follow-up .Results CSII significantly controlled the glucose levels ,reduced the TG ,TC ,LDL levels and the homeostasis model assessment of insulin resistance ( HOMA-IR) and increased the homeostasis model assessment of insulin secretion (HOMA-IS)(all P< 0 .05) .During 1-year follow-up ,HbA1c in the glargine group and the OAD group was (6 .13 ± 0 .47)% and(6 .21 ± 0 .38)% respectively .During 2-year follow-up ,the HbA1c values in the two groups were (6 .91 ± 0 .57)% and(6 .43 ± 0 .62)% respectively .T HOMA-IR and HOAM-IS obtained the long tern improve-ment without significant body weight increase .Conclusion Short-term intensive insulin therapy can effectively control the blood glucose ,improve the sensitivity of insulin and the β-cell function ;after CSII ,adopting basic insulin and oral antidiabetic drugs can a-chieve the ideal glycemic control .

Objective To investigate the operative treatment of displaced intra-articular fractures of the calcaneus using a small lateral incision approach.Methods Thirty-one patients with 32 intra-articular calcaneal fractures,were treated with open reduction and internal fixation through a small lateral incision approach from October 2004 to April 2006.The skin incision was made from the distal tip of the fibula to the base of the fourth metatarsal.According to Sanders classification,there were 21 typeⅡfractures and 11 typeⅢfractures.The first change of dressing was done on the second day after operation.The residual blood clots in the wounds were cleaned as much as possible when the drainage sheet was removed.The operated foot was bandaged with pressure dressing of cotton pad.Results After an average follow-up of 10.5 months(range,3 to 18 months),no soft tissue com- plications were found,and all had acceptable reduction.The preoperative X-ray film showed that B(?)hler angle was 6.84??9.36?,Gissane angle was 106.04??12.03?.The postoperative X-ray film demonstrated that B(?)hler angle was 32.06?+6.87?,Gissane angle was 115.81??9.48?,and the difference was statistically significant(P＜0.01).According to the AOFAS evaluation system for Ankle-Hindfoot,two feet scored 60-70 points,nine feet 70-80 points,16 feet 80-90 points and five feet 90-100 points.Condusion The small lateral incision approach is a good option for management of calcaneus fractures,because it causes minimal soft tissue damage,provides excellent exposure,and leads to convenience for later removal of internal fixators and subtalar arthrodesis.

This study was aimed to evaluate effects of traditional Chinese medicine ( TCM ) five elements music therapy on the quality of life for both senior and non-senior advanced cancer patients , and improve TCM com-prehensive treatment mode . A total of 170 patients were stratified according to 70-year-old in a randomized controlled trial ( RCT ) with a parallel single-blind design . The ratio of patients among three groups was 2:2:1 . In the experimental group , TCM five elements music was given in the treatment . In the positive control group , western music was used in the treatment . And in the negative control group , no music was given in the treat-ment . The treatment was given for 30 min , 5 times per week . And the observation duration was 3 weeks . The Hospice Quality of Life Index-Revised ( HQOLI-R ) , Karnofsky Performance Scale ( KPS ) and Symptom Diary Score recorded by patients were used in the evaluation . The results showed that when comparing HQOLI-R , KPS and Symptom Diary Score before and after treatment among all advanced cancer patients in each group , there was a significant difference before and after treatment in the TCM five elements music therapy group ( P< 0 . 05 ) . But there was no significant difference before and after treatment in the western music therapy group or the negative control group ( P > 0 . 05 ) . It was concluded that TCM five elements music therapy is effective in improving quality of life and subjective symptoms for both senior and non-senior advanced cancer patients . However , the sensitivity of using the Symptom Diary Score as an evaluation index among senior patients still needs to be further proved .

Objective To establish human choriocarcinoma JeG-3 cell line resistant to floxuridine (FUDR)and describe the characteristics of this FUDR-resistant subline.The thymidylate synthase (TS) expression level in FUDR-resistant subline was also discussed.Methods The FUDR-resistant sub-line JeG-3/FUDRA was established by intermitted exposure to grads increased FUDR.Reversed microscope was used to observe the morphological changes in FUDR-resistant sub-line.Population doubling time was calculated and compared based on the growth curve of these two cell lines,cell cycles and chromosomal ploidy were assayed with flow cytometry methods.The chemo-luminescence assay was used to detect the hormone secretion by two kinds of cell lines.The resistant index (RI) was measured by cell counting kit-8 (CCK-8)assay.Quantitative RT-PCR was used to detect the mRNA expression level of TS and we also detected the TS mRNA expression level in different doses exposed subline.Results The RI of JeG-3/FUDRA was 31.62.Compared with the JeG-3 cell,the FUDR-resistant cell line had gross changes in morphological,cell growth,cell cycles and chromosomal numbers.The ability of human chorionic gonadotrop(hCG) and progesterone secretion was lower in JeG-3/FUDRA subline.The trend of TS mRNA expression was:while exposed to low concentration of FUDR,the TS mRNA expression level was downregulated,then followed the increasing dose of the drug,the expression level of TS mRNA ascended gradually.When the terminal concentration was reached,the expression level of TS mRNA in JeG-3/FUDRA subline was higher than that of JeG-3 cell line (P＜0.05).Conclusions We established the FUDR-resistant subline of JeG-3 successfully.The TS mRNA expression level is stage-related to the different concentration and different phase in FUDR exposure.Our data suggested that TS mRNA expression level may not be used as a biomarker to predict the chemosensitivity in FUDR-based chemotherapy.

Surface electromyogram (sEMG) may have low signal to noise ratios. An adaptive wavelet thresholding technique was developed in this study to remove noise contamination from sEMG signals. Compared with convention- al wavelet thresholding methods, the adaptive approach can adjust thresholds based on different signal to noise ratios of the processed signal, thus effectively removing noise contamination and reducing distortion of the EMG signal. The advantage of the developed adaptive thresholding method was demonstrated using simulated and experimental sEMG recordings.

This paper was aimed to analyze and study the process of Turmeric fine pulverizing; and the powder properties of Turmeric ultra-micro powder after the process. Based on d50, the powder properties of Turmeric ultra-micro powder were summarized by using orthogonal design to select the optimal Turmeric fine pulverizing. Compari-sons were made on powder properties, such as exterior characters, IR spectra, fluidity and hygroscopicity before and after fine pulverizing. The results showed that optimal fine pulverizing process was determined based on orthogonal design. The conditions were that the material was 1 200 g, with water of 5.5% and crushing for 40 min. Compari-son of powder properties of Turmeric powders before and after fine pulverizing showed that as the diameter of the particle decreased. Turmeric particle gradually showed signs of aggregation. At the same time, granular sensation disappeared;the color turned lighter;powder became finer;fluidity was reduced;balanced hygroscopic capacity el-evated. Although the chemical composition and molecular structure had not changed;initial velocity and capacity of hygroscopicity increased, acceleration declined. It was concluded that Turmeric fine pulverizing was a convenient, reliable and practical process, with small size of particle. It can be used for Turmeric fine pulverizing. The compre-hensive evaluation showed that ultrafine powder four as the optimum powder.

Objectives To construct a cDNA subtractive library of dermal papilla cells (DPCs) in anagen with suppression subtractive hybridization (SSH) and clone differentially expressed genes related to DPCs in anagen. Methods Total RNA was isolated from DPC of anagen and telogen follicles. Then ds cDNAs were synthesized in turn using SMART cDNA synthesis technique. After cDNAs from anagen and telogen follicle DPCs were hybridized with each other twice and underwent two rounds of nested PCR, PCR products were ligated with arms of T/A plasmid vectors to set up the subtractive library. Selected clones were verified by reverse Nothern blot and DNA sequencing, and the acquired sequences were analyzed for homology based on Genbank nucleotide database. Results cDNA subtractive library of DPCs in anagen follicle was set up successfully with high subtractive efficiency. Thirty-five genes were identified with 22 known functional genes and 13 unknown functional genes. Conclusions These results demonstrate the effectiveness and sensitivity of SSH in detecting differentially expressed genes from a small amount of clinical samples. Information about such alterations in gene expression might be useful for elucidating the genetic events in hair follicle growth regulation.
