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 study the clinical correlated factors of renal damage in henoch-schonlein purpura (HSP).Methods One hundred cases with HSP were retrospectively studied. Accoding to the urinary route examination, the patients were devided into 2 groups, HSP with (49 cases) and without renal damaged (51 cases). In addition, the group of HSP with renal damaged was further diveded into 2 groups, HSP with urinary abnormality passingly (27 cases) and persistently (22 cases). Clinical indicators were statistical analysed.Results To be compared with HSP without renal damaged, age,apread of the purpura, abdominal pain,hemorrhage of digestive tract were higher in HSP with renal damaged (P

OBJECTIVETo observe the changes of electrocardiogram (ECG) and pregnancy outcome of the late pregnancy women.

METHODSLate pregnancy women were divided into two groups by age: over 35 group and under 35 group. The incidence of abnormal electrocardiogram was recorded when the patients were subjected to routine ECG examination. Then the pregnancy, delivery outcome and if there's low birth weight newborn were recorded later.

RESULTSThe incidence of abnormal ECG in over 35 group was significantly higher than that in under 35 group (P < 0.05). And the incidence of ST segment changes, arrhythmia in the group of former was higher than that in the group of latter (P < 0.05). Among the different type of arrhythmia, the incidence of sinus bradycardia and ventricular premature beat in the group of former were higher than those in the group of latter (P < 0.05). But the incidence of sinus tachycardia in the former group was obviously lower than that in the latter group (P < 0.05). The incidence of pregnancy loss in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal or abnormal ECG groups (P < 0.05). The incidence of premature birth in over 35 with abnormal ECG group was significantly higher than that in over 35 with normal ECG group (P < 0.05). The incidence of low body weight in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal ECG group (P < 0.05).

CONCLUSIONThe late pregnancy women with the age of over 35 are more likely to have ECG abnormalities, such as arrhythmia, myocardial ischemia and so on. The older pregnant women with abnormal ECG easily suffer from pregnancy losing, premature birth and having a low birth weight baby.

OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.

METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.

RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.

CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.

Multi-drug resistance is a major clinical challenge today. The good antibacterial effect of gold nanoparticles (AuNPs) based on their unique physical and chemical properties make such systems ideal for application as antibacterial drug carriers or self-modified therapeutic agents both in vitro and in vivo. AuNPs also have good clinical application prospects for their broad antibacterial spectrum, various antibacterial mechanisms and good biocompatibility. However, their structural stability in vivo, antibacterial mechanism, long-term safety and cytotoxicity of the surface modification have yet to be further explored and improved through subsequent studies.

OBJECTIVETo explore the time law of electroacupuncture in regulation of circadian rhythms of the organism.

METHODSEffects of electroacupuncture at "Shenshu" (BL 23) at Zi, Wu, Mao and You periods on circadian rhythms of locomotor activity and core body temperature in hamsters were observed with chronobiological research methods.

RESULTSElectroacupuncture at Wu period could decrease the amplitude of locomotor activity rhythm (P < 0.05), at Mao period could delay the peak phase of circadian rhythm and at You period could advance the peak phase of circadian rhythm (both P < 0.05); and electroacupuncture at Mao period could delay 22.36 degrees and at You period advance 39.32 degrees for the rhythm peak of the circadian rhythm of core body temperature.

CONCLUSIONAcupuncture has a certain effect on circadian rhythm of locomotor activity and core body temperature.

Objective To measure the expressions of cytotoxity-related cytokines in CD8+memory T cell subsets of peripheral blood in patients with multiple sclerosis (MS) and further analyze the relationship between the cytokine levels and MS disease severity. Methods Four-color flow cytometry was employed to detect the proportion of CD8+ memory T cell subsets expressed perforin and granzyme-B in peripheral blood of patients with MS, with other neurological disorders (OND) and of normal control (NC) group. The expanded disability status scale (EDSS) was used to reflect the disease severity at the time of blood sampling. Results Patients with MS had a decreased proportion of effector memory CD8+ T (CD8+ TEM) cells and terminal TEM cells expressed granzyme-B as compared with NC group (P＜0.05). CD8+ TEM cells expressed granzyme-B and perforin were negatively correlated to the scores of EDSS in patients with MS (r=-0.493, P=0.027; r=-0.594, P=0.009). Conclusions CD8+ TEM may be involved in the MS-related CNS inflammatory immune response. The proportion of CD8+ TEM cells expressed perforin and granzyme-B can be used to reflect the pathological severity of MS lesions to some degrees.

OBJECTIVETo investigate the feasibility of real-time elastography for quantitative evaluation of liver fibrosis in a rat model.

METHODSA total of 70 male Wistar rats were included in the group for dimethylnitrosamine (DMN)-induced liver injury, and 10 saline-injected rats were used as normal control. Hepatic injury was induced by a single intraperitoneal injection of DMN at a dose of 50 mg/kg of body weight. Nine or ten rats in the group with DNM injected and one or two rats in the normal control group were randomly selected and sacrificed at each of the following post-injection time: day 5, 7, 10, 14, 21, 24, and 28. And their livers were taken for pathology analysis. All the rats underwent real-time elastography before sacrificed in order to acquire area ratio of low-strain region (% AREA) and liver fibrosis index (LF index) which were compared with the stage of liver fibrosis and grade of necroinflammatory pathologically. By the different data, Spearman correlation analysis, rank-sum test or receiver operating characteristic curve was used.

RESULTSAmong 58 successfully modeled rats, there were nine, 13, 14 and 12 rats of S1, S2, S3 and S4 liver fibrosis on pathology, respectively, which were with or without mild necroinflammatory. The other 10 rats were found to be S0 with severe necroinflammatory. Values of LF index and % AREA both increased with liver fibrosis stage (P less than 0.05). There was certain correlation between LF index and liver fibrosis stage (r=0.643, P=0.000), so was % AREA and liver fibrosis stage (r=0.662, P=0.000). As for LF index, Areas under the receiver operating characteristic curve (Az) was 0.943, 0.890, 0.743 and 0.821 for the diagnosis of hepatic fibrosis S1 or higher, S2 or higher, S3 or higher and S4, respectively; as for % AREA, they were 0.948, 0.883, 0.772 and 0.842, respectively. However, we found a significant difference for LF index or % AREA between S0 with and without severe inflammatory activity rats (P=0.005 and P=0.017).

CONCLUSIONReal-time elastography is available for quantitative assessment of liver fibrosis in rats induced by DMN, but severe inflammatory activity can affect its accuracy.
