[Summary] _ Osteoporosis and diabetes mellitus are diseases which affect public heath severely, and osteoporotic fracture risk is increased in patients with diabetes. During recent years, new anti-diabetes drugs glucagon-like peptide-1(GLP-1) analogues and its receptor agonists had been used for diabetes treatment. As the research continues, besides of anti-diabetes, GLP-1 analogues are also found to play a role in bone metabolism and central nervous system by stimulating bone formation, inhibiting bone resorption, and nerve protection/nutrition, etc, suggesting that it may play an important role in the treatment of other diseases such as osteoporosis.

Objective To observe the clinical therapeutic effect of acupuncture combined with acupoint injection in the treatment of post -stroke intractable hiccup.Methods 120 patients with post -stroke intractable hiccup were randomly divided into treatment group(60 cases)and control groups(60 cases)according to the digital table.The patients in the control group were treated with baclofen tablets and methloxetamine hydrochloride injection, and the patients in the treatment group were treated with acupuncture combined with acupoint injection therapy.The treating period was 1 week.The scores of hiccup symptoms,the total effective rate and side effect were recorded before and after the treatment in all patients.Results The scores of hiccup symptoms before treatment in the treatment group and the control group were (5.32 ±1.17)points and (5.25 ±0.65)points respectively,there was no statistically significant difference between the two groups(t =1.79,P =0.96).The scores of hiccup symptoms on the 1 day after treatment in the treatment group and the control group were (3.97 ±1.24)points and (3.85 ±1.02 )points respectively,there was no statistically significant difference between the two groups(t =1.93,P =0.48).The scores of hiccup symptoms on the 3 days after treatment in the treatment group and the control group were (2.80 ±0.73)points and (3.75 ±1.11)points respectively,there was significant difference between the two groups(t =2.66,P =0.00), that in the treatment group was lower than the control group.The scores of hiccup symptoms on the 5 days after treatment in the treatment group and the control group were (2.25 ±1.07)points and (3.43 ±0.81)points respec-tively,there was significant difference between the two groups(t =2.85,P =0.00),that in the treatment group was lower than the control group.The scores of hiccup symptoms on the 7 days after treatment in the treatment group and the control group were (1.27 ±0.66)points and (2.02 ±0.98)points respectively,there was significant difference between the two groups(t =1.07,P =0.00),that in the treatment group was lower than the control group.The total effective rates in the treatment group and the control group were 90%(54 /60)and 65%(39 /60)respectively,there was significant difference between the two groups(χ2 =10.75,P =0.00).The incidence rates of side effects in the treatment group and the control group were 1.7%(1 /60)and 6.7%(4 /60)respectively,there was no statistically significant difference between the two groups(χ2 =0.84,P =0.36).Conclusion Acupuncture combined with acu-point injection can significantly reduce the hiccup symptom score of post -stroke intractable hiccup patients on the 3, 5 and 7 days after treatment,and improve the total effective rate.

Periostin is preferentially expressed in the periosteum, which covers a large majority of bones.Periostin has been reported to promote osteoblast proliferation, adhesion, and differentiation, involving bone repair process, response to mechanical stimulation and parathyroid hormone (PTH), regulating bone development/ remodeling and bone strength.Circulating periostin may serve as a candidate of biological markers for bone metabolism.

Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.ResultsTwo groups at T0, T1 esophageal temperature no significant difference, study group t2-t6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference (P<0.05), and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).ConclusionThe surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.

Objective To explore the molecular mechanism of glucocorticoid (GC)-induced osteoporosis (GIOP). Methods Thirty-two female SD rats after matching body weight were divided randomly into three groups: baseline group (n = 10), control group (n = 11) and GC-treated group (n = 11). The administration time was 9 weeks. Bone mineral density (BMD) was measured with dual energy X-ray absorptiometry. A high resolution micro-CT was used to quantify the densitometric and microarchitectural properties of trabeculae in the proximal metaphysis of right tibia. In situ hybridization histochemistry and immunohistochemistry were used to detect the expression of cannabinoid type 1 receptor (CBI R) in the proximal metaphysis of left tibia. Results At the end of the experiment, whole-body BMD in vivo in the control group [(0. 156±0. 008) g/cm2]was higher than that in the baseline group [(0.147±0.006)g/cm2], while the whole-body BMD in vivo [(0.147±0.006) g/cm2]and total BMD in vitro at femurs in the GC-treated group [(0.220±0.011) g/cm2]was lower than those in the control group [(0. 240±0. 024)g/cm2]. Compared with the baseline group and control group, there was a remarkable decrease in the volumetric BMD, tissue BMD, trabecular number and trabecular connectivity (P<0.05) in the GC-treated group, while there was a significant increase in trabecular separation (P < 0. 05) and trabecular thickness also increased in the proximal metaphysis of tibiae in the GC-treated group. The expression level of CB1R mRNA and protein in osteoclasts in the GC-treated group was markedly higher than that in the baseline group and control group (P < 0. 05). There was a close correlation between the expression level of CB1R mRNA, protein in osteoclasts and some microarchitectural parameters in the proximal metaphysis in the GC-treated group (P<0.05). Conclusions The administration of GC is associated with a decrease in BMD and deterioration in microarchitecture of trabecular bone in rats tibiae. Glucocorticoid may up-regulate the CB1R expression level in osteoclasts and this may be a kind of molecular mechanism of GIOP.

Serum osteoprotegerin (OPG) concentration was measured in 647 healthy female adults (aged 20-81 years), and was compared with that of other races. The serum OPG was positively correlated with age (r = 0.276, P <0.01). The geometric mean value of serum OPG in premenopausal women was significantly lower than those in perimenopansal and postmenopausal women. The serum OPG in middle-aged Chinese women was signifieandy higher than those in middle-aged Austrian and Icelandic, but this was quite contrary to the results obtained in old-aged women.

1,3-propanediol is an important raw material in chemical industry. Microbial conversion of glycerol or glucose into 1,3-propanediol has been given much attention due to its renewable resource, mild reaction conditions, and other advantages. It is a challenge to efficiently separate 1,3-propanediol from a mixture of multiple components, such as 1,3-propanediol, 2,3-butanediol, water, residual glycerol, ethanol, macromolecules and salts, for the reason that 1,3-propanediol, glycerol and 2,3-butanediol are all very hydrophilic and have intense polarity. The conventional evaporation and distillation techniques used in the purification of 1,3-propanediol suffer from the problem of high energy consumption and low recovery. It makes the recovery of 1,3-propanediol from a fermentation broth become a bottleneck in industrial production. The down-stream processing of biologically produced 1,3-propanediol mainly includes the removal of protein, salts, water and other impurities. This paper analyze the research progress of these separation technologies and point out the developing direction worth further investigation.

Wheat peroxidases 1 (WP1) is the major cationic peroxidase of wheat (Triticum aestivum) grain, which is involved in the development of seeds and an important factor to affect the final processing quality of flour. We constructed a prokaryotic expression vector pET28a-WP1, and transformed it into E. coli host strain T7 Expression. His-tag fused WP1 existed as inclusion body, and the recombinant protein was purified by Ni-NTA resin affinity chromatography under denatured condition. The purity of target protein reached 98%. The recombinant WP1 was refolded by gradient urea dialysis, then used as antigen to immune rabbit to prepare polyclonal antibody. The result of ELISA showed that the titer of rabbit anti-WP1 antiserum was higher than 1:625 000. The result of Western blotting demonstrated that the prepared WP1 polyclonal antibody could be used to detect WP1 with high specificity.
