Lu's acupuncture was found by two senior doctors, Lu Shou-yan and Zhu Ru-gong. As one of large schools in acupuncture academic circles in our country, Lu's acupuncture has relatively complete academic thought and theoretical system, and unique characteristics of clinical diagnosis and treatment. Doctor Su Zhao-jia studied under doctor Lu Shou-yan and inherited Lu's academic thought and diagnostic and therapeutic techniques. In decades of clinical practice, doctor Su adhered to Lu's acupuncture's treatment idea, treated diseases under the guidance of meridian theory and on the basis of syndrome differentiation, paid attention to acupuncture manipulation and accumulated relatively abundant clinical experience in applying acupuncture to composite treatment of senile vaginitis.

Objective To study the effect of glutamine on hypermetabolism reaction and hormone secretion after severe burn injury. Methods Eighty-eight Wistar rats were inflicted with 30% total body surface area full thickness burns and randomly divided into two groups: namely burned control (B) and glutamine treatment(GLN) group. There was isonitrogenous and isocaloric intake in both groups, and rats of GLN and B groups were given glutamine and glycine at 1 0g/kg d, respectively. The following indices including the resting energy expenditure (REE), the levels of plasma cortisol, insulin and glucagon were determined. Results After burn injury, the REE, plasma cortisol,insulin and glucagons levels were significant increased in both groups. Compared with B group, the level of REE decreased and the ratio of insulin/glucagons increased in GLN group. Correlation analyses showed that REE had a negative correlation with insulin/glucagons ratio (r=-0 78,P

Aim Poly (methoxypolyethyleneglycol cyanoacrylate-co-hexadecyl cyanoacrylate) (PEGPHDCA) and PHDCA niosomes were prepared and the influence of the PEG chain length on the niosomes physicochemical characteristics, complement consumption and phagocytic uptake were studied. Methods The physicochemical parameters of PEG-PHDCA niosomes were characterized in terms of particle size, zeta potential, surface PEG density and fixed aqueous layer thickness. The relationship between physicochemical characteristics and in vitro complement consumption and phagocytic uptake was further illustrated. Results Experimental results showed that PEG10000-PHDCA had most loose structure and least PEG surface density among three groups. Configuration simulation through fixed aqueous layer thickness confirmed that PEG folding and less flexibility of the PEG chains of PEG10000-PHDCA niosomes were accountable for its poor stealth effects. Compared with PEG2000-PHDCA, PEG5000-PHDCA showed a thicker fixed aqueous layer (FALT) of 4. 20 nm, less negative zeta potential of -10.03 mV, and consumption and phagocytic uptake. Conclusion Excessive chain length of PEG was not necessary for stealth effects of PEG-PHDCA niosomes. PEG5000-PHDCA niosomes had best effects on evading complement consumption and subsequent phagocytic uptake.

Objective To explore the effect of the ?-blocker —metoprolol on the treatment of vasovagal syncope(VVS) in children.Methods Twenty-nine children with unexplained syncope and positive responses to head-up tilt test(HUT) were included in the study.Sixteen of them took metoprolol(treatment group) and 13 of them took vitamin B or oryzanol (control group) at least 2 weeks and HUT were repeated and syncope episodes were observed.Results In treatment group,9 of 16 patients had no syncope episode while 5 of 16 patients had fewer syncope episodes,1 case had more syncope episodes,and 1 case remained the same.HUT were repeated and 6 of 9 cases had negative outcome.In control group,1 of 13 patients had no syncope episode while 5 of 13 patients had fewer syncope episode,3 cases had more syncope episodes and 4 cases remained the same.HUT were repeated and 3 of 7 cases had ne-(gative) outcome.Conclusion These results indicate that adminstering metoprolol orally may be effective for VVS in children.

0.05).However,metabolic acidosis and hyperchloremia were observed with feeding arginine hydrochloride for 7 days in severe burned rabbits,and no such significant changes were found in arginine acetate group.CONCLUSION:Arginine acetate is safer than arginine hydrochloride in severe burned rabbits.

Objective To investigate the effect of hypertension on the large artery elasticity index (C1),the small artery elasticity index (C2) and the medial structure of the ascending aorta as well as the relationship between artery elasticity and the medial structure of the ascending aorta.Methods Sixty patients with CHD receiving coronary artery bypass graft surgery at our hospital were divided into two groups:30 patients in the hypertension group and 30 patients in the non-hypertension group.C1 and C2 were measured using the CVProfilor DO-2020 system.Sections of tissues taken from the anterior wall of the ascending aorta during the surgery were subjected to Masson's trichrome staining for the detection of vascular smooth muscle and collagen fibers and Weigert's resorcin-fuchsin staining for the detection of elastic fibers.The relative areas of vascular smooth muscle fibers,collagen fibers and elastic fibers of the ascending aorta were measured by a computer image analysis system under the light microscope.The linear correlations of C1 and C2 with the medial structure of the ascending aorta were analyzed.Results C1 in the non hypertension group was higher than that in thehypertensiongroup[11.9±1.8 (ml/mmHg×10) w 13.1±2.5 (ml/mmHg×10),t 2.22,P ＜0.05].In the media of the ascending aorta,the relative content of collagen fibers was higher,while the relative content of elastic fibers was lower in the hypertension group than in the non-hypertension group [(46.0±3.8)％ w (42.2±3.0)％,(17.5±3.5)％ vs.(19.3 2.7)％,respectively,t=4.24 and 2.20,P＜0.01 or 0.05].C1 was positively correlated with the relative content of elastic fibers but negatively correlated with the relative content of collagen fibers in both groups (r=0.52 and 0.39,respectively,P＜0.05 or 0.01).Conclusions The main pathogenic basis of hypertension-induced decline in arterial elasticity in CHD patients is increased collagen fibers and reduced elastic fibers with disorganization of the two types of components.C1 may accurately reflect the effect of hypertension on medial collagen fibers and elastic fibers in the ascending aorta.
