Objective To explore the perioperative efficiency and safety of different regimen of tranexamic acid (TXA) in total knee arthroplasty (TKA).Methods From February 2013 to May 2013,150 female patients with knee osteoarthritis underwent unilateral TKA were randomly divided into three groups,50 cases in each group.Patients received 10 mg/kg TXA by fast intravenous infusion before closing the wound in first group (single dose group),patients in second group received two doses of 10 mg/kg TXA before closing the wound and 3 hours postoperation (repeated dose group),patients in the third group didn't receive TXA (control group).The postoperative blood loss via drainage,the total blood loss,the hidden blood loss,the postoperative hemoglobin concentration at different times and the numher of patients need blood transfusion were recorded.All patients were observed for detecting deep vein thrombosis (DVT) by the color doppler ultrasonography within 5 days postoperation,and the symptomatic DVT and pulmonary embolism (PE) were observed within 90 days postoperation.Results The blood loss via drainage was significantly less in the single dose group (273.6±99.6 ml) and repeated dose group (168.5±80.8 ml) compared with the control group (447.2±101.9 ml),and it was significantly less in the repeated dose group than the single dose group; the total blood loss was significantly less in the single dose group (959.1±291.7 ml) and repeated dose group (818.7±206.9 ml) compared with the control group (1 100.8±288.3 ml),and it was significantly less in the repeated dose group than in the single dose group; there was no differ ences about the hidden blood loss among the three groups.The hemoglobin concentration was significantly higher in the single dose group and repeated dose group than in the control group in day 1,3 and 5 postoperation; and it was significantly higher in the repeated dose group compared with the single dose group.The ratio of transfusion was significantly less in the single and repeated dose groups than in the control group,but no differences exists between the single dose group and repeated dose group.There was no DVT in all of the three groups within 5 days postoperation,and there was no symptomatic DVT and PE in all of the three groups within 90 days.Conclusion 10 mg/kg of TXA infused intravenous before closing the wound is effective and safe in TKA,another dose 3 hours postoperation is much more effective and will not increase the danger of DVT and PE.

Objective: To analyze the relationship between hemoglobin ( Hb ) and serum uric acid ( SUA ), so as to provide basis for preventing hyperuricemia ( HUA ) . Methods: As the research subjects, people who underwent physical examination in Zhejiang Provincial People's Hospital from January 1, 2017 to October 31, 2020 for 4 years in a row and who were non-HUA in 2017 were selected. The physical examination data were collected, including body mass index, blood pressure, blood routine, blood biochemical tests, etc. The subjects grouped by quartiles of Hb level in 2017. The occurrence of SUA elevation ( SUA increased ≥60 μmol/L from baseline ) , significantly SUA elevation ( SUA increased ≥120 μmol/L from baseline ), HUA ( SUA>420 μmol/L ) and severe HUA ( SUA ≥480 μmol/L ) in the next 3 years were taken as end events. The incidence, occurrence time and risk of end events in different Hb groups were analyzed. Results: A total of 4 073 subjects were selected and divided into 4 groups according to the Hb level from low to high, with 969 subjects in group A, 907 subjects in group B, 1 109 subjects in group C and 1 088 subjects in group D. SUA elevation was in 745 patients ( 18.29% ); significantly SUA elevation was in 105 patients ( 2.58% ); HUA was in 514 patients ( 12.62% ); severe HUA was in 94 patients ( 2.31% ). The incidence of SUA elevation and significantly SUA elevation showed a decreasing trend with the increase of Hb level ( P<0.05 ). The occurrence time of SUA elevation in group A to D was 2.788, 2.817, 2.860 and 2.814 years, and the difference was statistically significant ( P<0.05 ). There were no statistically significant differences in the occurrence time of other end events ( P>0.05 ). The multivariate Cox proportional hazards regression analysis showed that compared with group A, other Hb groups had lower risk ( HR=0.498-0.776, 95%CI:0.253-0.981 ) of SUA elevation, significantly SUA elevation and severe HUA after adjusting for gender, age, ALT, Scr, body mass index, etc. Conclusions With the increase of Hb level, the incidence of SUA elevation may decrease and the occurrence time is prolonged. Compared with the lowest Hb group, the higher Hb groups had lower risk of SUA elevation, significantly SUA elevation and severe HUA.

Acupuncture-moxibustion theory believes that needling sensation is a crucial factor in influencing acupuncture efficacy. Judgment of occurrence of needling qi (qualitative measurement) and the intensity of needling qi (quantitative measurement) is the key section in studying the relationship between needling qi and efficacy. According to the relevant literatures, the judgment of the occurrence of needling qi mostly depended on the needling sensations, while a small amount of researches mentioned self-determined threshold or range of needling qi; the quantity of needling qi was measured by factor analysis, Massachusetts General Hospital Acupuncture Sensation Scale (MASS) based on exponential smoothing method, weighted average, addition of needling sensation score, etc. This article holds that the needling qi should be divided into two parts: overall needling qi and needling sensation components, the former referring to the occurrence and intensity of needling qi, and the latter for judging the different sensations and intensity. Currently, the studies on needling qi and efficacy should begin with single treatment at single point and multiple treatments at multiple points, to generally estimate the quality and quantity of needling qi, for seeking a qualitative and quantitative measurement in accordance with both acupuncture-moxibustion theory and clinical practice.

Objective By using infrared thermal imager (Flir-SC620), to observe the effect of needling Sanyinjiao (SP6) on the skin temperature at Guanyuan (CV4) and Sanyinjiao in patients with primary dysmenorrhea (PD) of cold and dampness stagnation pattern, and to explore the probability of using infrared thermal imaging for diagnosis and as an objective index for evaluating the action and needling qi of acupuncture. Method Thirty-six subjects were recruited and divided into four group, a health control group (group A), a control group of PD of cold and dampness stagnation pattern (group B), a needling-qi-expected group (group C) and a needling-qi-unexpected group (group D). Group A and B were not given acupuncture treatment, while group C and D were treated with acupuncture at bilateral Sanyinjiao with needles retained for 30 min, and the needling sensations were recorded. The infrared thermal imager was used to detect the skin temperature at Guanyuan and bilateral Sanyinjiao for 40 min for each group, and the temperature was recorded every 10 min. The temperature during different periods of time, 0-10 min, 20-20 min, 20-30 min, 30-40 min, 0-30 min, and 0-40 min were then calculated. In group C, those obtained the needling qi sensation were further grouped into C-1 and those didn’t obtain the sensation were into C-2; in group D, those obtained needling qi sensation were further grouped into D-1 and those didn’t obtain the sensation were into D-2. SPSS 17.0 was adopted for data processing, and the data were analyzed by using MANOVA of repeated measuring. Result Compared to group A (6 cases), the temperature at Guanyuan in group B (6 cases) was significantly decreased during 0-30 min and 0-40 min (P<0.05), the temperature at the left Sanyinjiao during 0-40 min in group B was significantly decreased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group B significantly dropped (P<0.05). Compared to group B, the temperatures at Guanyuan during 0-30 min and 0-40 min in group C1 (12 cases) and group D1 (11 cases) were significantly increased (P<0.05), the temperature at left Sanyinjiao during 0-40 min in group D1 was significantly increased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group D1 were significantly increased (P<0.05). There was no case in group C2 and only 1 case in group D2, hence, the data were not enough for analysis. Conclusion Decrease of the infrared temperature at Guanyuan and Sanyinjiao can be taken as one of the diagnostic criteria for dysmenorrhea of cold stagnation pattern. Increase of the infrared temperature at Guanyuan can be regarded as one of the objective evidences for the along-meridian transmission characteristic in needling Sanyinjiao.

Chinese medicinal authentication is fundamental for the standardization and globalization of Chinese medicine. The discipline of authentication addresses difficult issues that have remained unresolved for thousands of years, and is essential for preserving safety. Chinese medicinal authentication has both scientific and traditional cultural connotations; the use of scientific methods to elucidate traditional experience-based differentiation carries the legacy of Chinese medicine forward, and offers immediate practical significance and long-term scientific value. In this paper, a path of inheritance and innovation is explored through the scientific exposition of Chinese medicinal authentication, featuring a review of specialized publications, the establishment of a Chinese medicine specimen center and Chinese medicinal image databases, the expansion of authentication technologies, and the formation of a cultural project dedicated to the Compedium of Materia Medica.

OBJECTIVETo investigate the effects of ghrelin on the proliferation and differentiation of 3T3-L1 preadipocyte, and study the possible mechanisms.

METHODS3T3-L1 preadipocytes were cultured in vitro. The proliferation potentials of 3T3-L1 preadipocytes that were treated with different concentrations of ghrelin were evaluated by MTT methods. The levels of c-myc and thymidine kinase mRNA were detected using RT-PCR. 3T3-L1 preadipocytes were differentiated into the matured adipocytes with insulin (INS) or ghrelin. The morphological changes of 3T3-L1 adipocytes were observed and the differentiation rate was assayed by oil-red O staining. Total RNA was extracted from adipocytes at various times, and the levels of peroxisome proliferation activated receptor gamma (PPARgamma) and CAAT/enhancer binding protein(C/EBPalpha) mRNA expressions were detected using RT-PCR.

RESULTSGhrelin at concentrations of 10(-7) to 10(-15) mol/L significantly stimulated preadipocyte proliferation (p<0.05). The levels of c-myc and thymidine kinase mRNA significantly increased in 3T3-L1 preadipocytes with 10(-9) mol/L and 10(-11) mol/L ghrelin treatment (p<0.01). The 3T3-L1 preadipocytes treated with 10(-11) mol/L ghrelin had lots of lipid droplets in the cytoplasma, but the differentiation rate was lower than those treated with INS. Ghrelin of 10(-11) mol/L significantly increased the mRNA expression of PPARgamma and C/EBPalpha in the course of 3T3-L1 preadipocyte differentiation, compared with the normal control group (p<0.05). The PPARgamma and C/EBPalpha mRNA expression increased with the prolonged differentiation of preadipocytes induced by ghrelin or INS. There were significant differences in the levels of PPARgamma and C/EBPalpha mRNA expression between the 2nd and 8th days of differentiation(p<0.01).

CONCLUSIONSGhrelin promotes the proliferation and differentiation of 3T3-L1 preadipocytes. The proliferation of 3T3-L1 preadipocytes induced by ghrelin may be associated with increased c-myc levels. Ghrelin may promote differentiation of 3T3-L1 preadipocytes by increasing mRNA expression of PPARgamma and C/EBPalpha, thus enhances the sensitivity of adipocytes to INS.
