Objective To investigate the incidence of osteoporosis (OP) in patients with ankylosing spondylitis and the relationship between OP and the clinical data. Methods Serum levels of bone alkaline phosphatase (BALP) and tartrate resistant acid phosphatase 5b (TRACP5b) were detected by enzyme linked immunosorbent assay ( ELISA ) in 60 cases with ankylosing spondylitis, and it was compared with normal controls. Bone mineral density (BMD) was measured through dual-energy X-ray absorptiometry ( DXA), including lumbar ( L2 - L4), bilateral femoral neck and greater trochanter. Some clinical data was collected and analyzed at the same time. Results The incidence of OP in AS patients was 35%, and the incidence of OP in the femoral proximal end was higher than that in lumbar. Compared with normal controls[ ( 1.06 ±0. 18 )U/L ], the levels of serum TRACP5b in AS[ (1.31 ± 0. 82 )U/L] patients was significantly higher ( P <0. 05 ). The levels of serum BLAP in OP combined AS group[ ( 21.65 ± 5.41 ) U/L]were significantly lower than non-OP group[ (32. 37 ± 16. 5 ) U/L] ( P <0. 05 ). The disease duration was negatively correlated with the BMD of femoral neck ( P < 0. 01 ). Conclusions There was higher incidence of OP in AS patients, which were related with the abnormality of bone metabolism and the disease duration.Multiple factors participated in the regulation of bone metabolism of AS.

Linoleic acid (C18∶2n-6) and ?-linolenic acid (C18∶3n-3) are found widely in fungi, plants and some lower animals. However, they can not be synthesized in mammals due to lack of △12 and ?-3 fatty acid desaturases. To enable endogenous production of essential fatty acids in mammalian cells, here the stable expression of a Caenorhabditis elegans gene FAT-2 encoding △12 fatty acid desaturase in CHO cells was reported. First, the FAT-2 coding sequence was cloned by RT-PCR. To facilitate high level synthesis of heterogeneous protein, the codon usage of the fatty acid desaturase genes was optimized according to the codon preference of mouse by site-directed mutagenesis, 2 synonymous mutations were introduced into FAT-2 gene by overlapping PCR. The codon-modified gene was finally fused to pBudCE4.1 vector (Invitrogen) under the control of CMV promoter. The expression vector pBudCE-FAT2 was linearized with NheⅠ, and then transfected CHO cells, the cells were under Zeocin selection for nine days and then propagated, then the transfected cells were harvested. The genome and total RNA were isolated for PCR and Norhern blot ananlysis. The results revealed that FAT-2 gene has been integrated into the genome of CHO cells and expressed properly. Fatty acids of total cellular lipids were analyzed by gas chromatography. The results indicate that the expression and function of △-12 fatty acid desaturase resulted in accumulation of linoleic acid. The levels of linoleic acid in transgenic cells were 2.4-fold higher than those in wild-type cells. The moderate linoleic acid in CHO cells was derived from cell culture media uptaken by cell membrane. The results demonstrate that a heterogenous desaturase gene can function well in mammalian cells and prove that transgenic approach is an efficient strategy for changing fatty acid composition of mammals.

OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.

METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).

RESULTThe TLC was well separated with clear spots. The linear range of phaseoloidin was between 0.014 to 2.747 g x L(-1) (r = 0.999 6, n = 9) with an average recovery rate of 101.06% (RSD 0.90%, n = 6); the linear range of entadamide A-O-β-D-glucopyranoside was between 0.002 to 0.452 g x L(-1) (r = 0.999 7, n = 9) withan average recovery rate of 101.52% (RSD 1.09%, n = 6). The content of phaseoloidin in sample is between 5.12% to 9.24%, entadamide A-O-β-D-glucopyranoside is between 0.55% to 2.17%, alcohol-soluble extracts is between 30.9% to 45.2%, water is between 6.6% to 8.6%, and total ash is between 2.4% to 2.9%.

CONCLUSIONThe established standard is acceptable for quality control of Entadae Semen.

Objective To observe the time-effect relationship between acupuncture treatment and the absorption of cerebral hematoma and edema in the acute stage of cerebral hemorrhage to determine the optimal time for acupuncture intervention in cerebral hemorrhage.Methods Three hundred patients with cerebral hemorrhage in the acute stage were randomly allocated to treatment groups 1, 2, 3 and 4, and control group, 60 cases each. The control group received symptomatic treatment for regulating blood pressure, reducing intracranial pressure by dehydration, maintaining electrolyte balance, nourishing nerves and preventing and treating complications. The treatment groups were given acupuncture in addition. Treatment group 1 received acupuncture at 24 hrs after the attack; treatment group 2, at 72 hrs; treatment group 3, at one week; treatment group 4, at two weeks. Pre-/post-treatment hematoma size parameter difference value and cerebral peripheral edema grade parameters were observed in every group.Results There were statistically significant pre-/post-treatment differences in hematoma size and cerebral edema grade in every group (P<0.01,P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between every treatment group and the control group (P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between treatment group 1, 2 or 3 and treatment group 4 (P<0.05), between treatment group 1 or 2 and treatment group 3 (P<0.05) and between treatment groups 1 and 2 (P<0.05).Conclusions Acupuncture has a positive therapeutic effect in patients with cerebral hemorrhage in the acute stage. The earlier acupuncture intervention in the acute stage of cerebral hemorrhage, the more remarkable the effect.

Objective To investigate the effects of up?regulated miR?206/miR?1 on the proliferation of breast cancer stem cells and the effect mech?anism. Methods Breast cancer stem cells(BCSCs)were isolated from breast cancer cell line MCF?7 by fluorescence?activated cell sorting. Cells in the experiment were divided into the blank control group,the negative control group,the miR?206 group and the miR?1 group. The BCSCs were transfected by negative control mimic,hsa?miR?206mimic and hsa?miR?1mimic in all groups except the blank control group. MiR?206and miR?1 expression levels as well as the transcription factor EVI?1 gene were detected by real time PCR. The expression levels of the transcription factor EVI?1 protein were detected by Western blot. MTT method was used to detect the effects of miR?206 and miR?1 on the proliferation of BCSCs. Results The BCSCs(CD44+/CD24-/low cells)isolated from MCF?7 cell lines were successfully cultured in serum?free medium for subsequent studies. After transfection of hsa?miR?206mimic and hsa?miR?1mimic for 48 hours,miR?206and miR?1relative expression levels increased. EVI?1mRNA ex?pression levels significantly decreased. The results of Western blot and MTT showed that up?regulated expression levels of miR?206 and miR?1 could significantly reduce the expression of EVI?1 protein and inhibited the proliferation of BCSCs. The differences in levels of miR?206,miR?1 and EVI?1 protein were statistically significant(P<0.05). Conclusion Up?regulated miR?206 and miR?1 expression can inhibit the proliferation ability of BCSCs,which may be related to the down?regulation of EVI?1.

Objective To study transmission characteristics of Acinetobacter baumannii (A.baumannii )clone and clinical features of infected patients in a respiratory intensive care unit (RICU),so as to guide the effective pre-vention and control of A.baumannii transmission.Methods 40 A.baumannii strains isolated from RICU patients were performed homology analysis by pulsed-field gel electrophoresis (PFGE)and cluster analysis,relationship of strains was determined,antimicrobial resistance and clinical data were analyzed.Results 40 A.baumannii strains were divided into 11 genotypes(A-K),the main epidemic strains were type A,B and E.The resistant rate to imipen-em was the lowest(70.00%),the next was levofloxacin (77.50%).The average age of 40 infected patients was 67 years old,the average length of hospital stay was 41 days,12 patients died because of invalid treatment.There was overlapping hospitalization among patients infected with type A and E strains;among patients infected with type B strain,there was no overlapping hospitalization among the last 6 and first 6 infected patients.Conclusion The main epidemic strains of A.baumannii were type A,B and E,antimicrobial resistant rate is high;the infected patients are with high average age and long length of hospital stay.It is important to reduce the transmission of A.baumannii through rational use of antimicrobial agents,strict aseptic operation,and intensified disinfection and sterilization of hospital environment and medical devices.

Objective To observe the effect of acupuncture on the expression of nitricoxide synthase (NOS) in gastrointestinal tissues after operation for incomplete intestinal obstruction in rats, and to explore the mechanism of acupuncture in promoting the recovery of gastrointestinal motility. Methods Forty Sprague-Dawley (SD) rats were randomized into treatment group 1, treatment group 2, model group 1, model group 2, and a normal control group, 8 rats in each group. The incomplete intestinal obstruction models were developed by using single ligation method in treatment groups and model groups. Afterwards, the treatment groups were intervened by acupuncture at Zusanli (ST 36) and Yanglingquan (GB 34), and rats in treatment group 1 and 2 were respectively dissected after 1-day and 2-day treatment. The rats in model group 1 and 2 were respectively dissected 1 d and 2 d after modeling. The morphological observation was performed on rat’s intestinal tissues, and the average diameter of the upper part of the obstructed intestine and the expression of NOS in gastrointestinal tissues were compared. Results The average ileocecal diameter after modeling was significantly different from that in the normal control group (P<0.05). There was a significant difference in comparing the ileocecal diameter between model group 1 and 2 (P<0.05). The ileocecal diameter in treatment group 1 was significantly different from that in treatment group 2 and model groups (P<0.05). The ileocecal diameter in treatment group 2 was insignificantly different from that in the normal control group (P>0.05). The NOS content in model groups was significantly different from that in the normal group (P<0.05). The NOS content in treatment group 1 was markedly different from that in model groups and treatment group 2 (P<0.05) after intervention. There were no significant inter-group differences in comparing NOS content (P>0.05). Conclusions Acupuncture can promote the recovery of gastrointestinal motility by regulating intestinal NOS content in rats after operation for incomplete intestinal obstruction.
