Objective To evaluate the effect of point-of-care hemoglobin/hematocrit (POC HGB/HCT) devices and intraoperative blood salvage on the amount of perioperative allogeneic blood transfusion and blood conservation in clinical practice.Methods A total of 46 378 medical records of 22 selected hospitals were reviewed. The volume of allogeneic red blood cell and plasma, number of patients transfused, number of intraoperative autologous blood salvage, total volume of autologous blood transfusion, and amount of surgery in the year of 2011 and 2013 were tracked. Paired t-test was used in intra-group comparison, while t-test of two isolated samples carried out in inter-group comparison. P<0.05 was defined as statistically significant difference.Results In the hospitals where POC HGB/HCT device was used (n=9), the average allogeneic blood transfusion volume per 100 surgical cases in 2013 was significantly lower than that in 2011 (39.86±20.20 vs. 30.49±17.50 Units, t=3.522, P=0.008). In the hospitals without POC HGB/HCT meter, the index was not significantly different between 2013 and 2011. The average allogeneic blood transfusion volume was significantly reduced in 2013 than in 2011 in the hospitals where intraoperative autologous blood salvage ratio [autologous transfusion volume/(autologous transfusion volume+allogeneic transfusion volume)] was increased (n=12, t=2.290, P=0.042). No significant difference of the above index was found in the hospitals whose autologous transfusion ratio did not grow.Conclusion Intraoperative usage of POC HGB/HCT devices and increasing autologous transfusion ratio could reduce perioperative allogeneic blood transfusion.

Objective To observe the effect of acupuncture on cystathionine gamma-lyase(CSE)and myeloperoxidase (MPO) in the colonic tissues of rats and to explore its mechanism for recovering the function of interstitial cells of Cajal(ICCs)in rats after colonic anastomosis . Methods Thirty SD rats were randomized into normal control group, model group(receiving colonic anastomosis) and acupuncture group. The acupuncture group received foot three-needle therapy on bilateral Zusanli(ST36), Sanyinjiao(SP6) and Taichong(LR3), once a day for 3 days after colonic anastomosis. And then the propulsive rate of the small intestine was measured. The count of ICCs with positively expressive c-kit in rat colonic tissues was measured by immunohistochemistry, the activity of CSE was observed by enzyme-linked immunosorbent assay (ELISA) and the activity of MPO was tested by biochemical method. Results Compared with the normal control group, the small intestinal propulsive rate in the model group was decreased, the number of ICCs with positively expressive c-kit was reduced, while the activities of CSE and MPO were increased(P<0.05). The acupuncture group had higher intestinal propulsive rate, more ICCs with positively expressive c-kit, and lower CSE and MPO activities than the model group(P<0.05).Conclusion Acupuncture can promote the recovering of postoperative gastrointestinal function, and its mechanism may be related to the regulation of CSE and MPO activities in the colonic tissues and to the restoration of ICCs function in the focus with positive c-kit.

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

OBJECTIVETo study the effect of Shugan Jiangu Recipe (SJR) on bone mineral density (BMD) and serum bone metabolic biochemical markers in postmenopausal breast cancer patients with osteopenia.
METHODSTotally 38 patients of postmenopausal women with breast cancer, who received aromatase inhibitors (AIs), were assigned to the treatment group (21 cases) and the control group (17 cases) by using random digit table. All patients took Caltrate D Tablet (containing Ca 600 mg and Vit D3 125 IU), one tablet daily. Patients in the treatment group took SJR, 6 g each time, twice daily for 6 successive months. The bone mineral density (BMD) level was detected before treatment and at months 6 after treatment. Levels of bone alkaline phosphatase (BALP), bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), and C-terminal telopeptide of type II collagen (CTX-II) were detected by enzyme linked immunosorbent assay (ELISA). The drug safety was also assessed.
RESULTSCompared with before treatment, BMD of L2-4 and femur neck obviously increased in the treatment group at month 6 after treatment (P < 0.01), serum BALP and TRAP decreased (P < 0.05). Compared with before treatment, BMD of L2-4 and femur neck obviously decreased in the control group at month 6 after treatment (P < 0.05), serum BALP and TRAP increased (P < 0.01). Compared with the control group, lumbar and femur neck BMD obviously increased, serum levels of BGP and BALP obviously decreased, and serum levels of CTX-II and TRAP obviously increased in the treatment group at month 6 after treatment (P < 0.01). No serious adverse event occurred during the treatment period. Bone fracture occurred in one case of the control group (5.8%).
CONCLUSIONSJR could attenuate bone loss of postmenopausal women with breast cancer who received AIs, increase BMD and improve abnormal bone metabolism.
