Bilateral lung lavage was performed under general anesthesia with muscle relaxation in 3 patients with pulmonary alveolar proteinosis(PAP)aged 43-57 yrs weighing 48-68 kg.Left lung lavage was performed first and the right lung was lavaged one week later.Left radial artery and right internal jugular vein were cannulated for MAP,HR and CVP monitoring.SpO_2 and P_(ET) CO_2 were monitored during lavage.Left-sided Robertshaw double-lumen tube was used for both right and left lung lavage.After proper placement of the double- lumen tube was verified both lungs were ventilated with 100% O_2 for 10 min to wash out N_2.Hyperoxygenated lavage fluid was made by aerating the lactated Ringer's solution with 100% O_2 at 1 L?min~(-1) flow rate for 30 seconds.The tidal aliquot of lavage was 700 ml which was kept in the lung for 50 seconds and then drained.Each lung was lavaged with hyperoxygenated and plain lactated Ringer's solution 10 times each alternatively.While one lung was being lavaged the contralateral lung was mechanically ventilated with 100% O_2.SpO_2,MAP,HR,CVP and P_(ET)CO_2 were recorded immediately before lavage and at 10,20,30,40,50,60,70 and 80 seconds after the lung was filled with lavage fluid.SpO_2 was significantly higher during lavage with hyperoxygenated fluid than with ordinary lactated Ringer's solution,but there was no significant difference in MAP,HR,CVP and P_(ET)CO_2.The PaO_2 of the 3 patients breathing room air was 46-52 mm Hg before lung lavage and increased to(72.3?2.1) mm Hg one week after left lung lavage and to(83.5?4.8)mm Hg 3d after right lung lavage.During the lung lavage,hyperoxygenic significantly improve oxygen supply in patients with pulmonary alveolar proteinosis compared with lactated Ringer's solution.

The research of traditional Chinese medicine (TCM) has failed to achieve major breakthrough, especially on some important and fundamental medical problems and concepts. One of the reasons for such failure is that the methodology used in the TCM research follows basically the path of partitioned reductive analysis, which is unable to capture practically the characteristics of TCM scientific system, such as the holistic and dynamic nature of diseases, and the interaction among various biological components. The systemic thinking and strategy of the systematic biology and its aim at grasping integral function have provided unprecedented enlightenment for the modem TCM research. To conduct a systemic strategic reductive analysis on human body and diseases under the guidance of holistic view will be an utmost important way for developing TCM towards the future of healthcare. The modernization of TCM does not have to follow the partitioned reductive approach, which has been practiced in the development of modern science in recent centuries. Instead, it should proceed in a "top down" way of systemic research by firstly investigating and understanding the systemic information, followed by a layered excavation on local information, so as to stride over the gap between the traditional medicine and the future medicine.

AIMTo prepare liposomes of nosiheptide and study its ability to inhibit hepatitis B virus HBsAg and HBeAg secreted.

METHODSLiposomes of nosiheptide was prepared by sodium deoxycholate dialysis and sonication. Nosheptide was determined by HPLC and partical size was determined by using laser light scattering instrument. Transmission electron microscopy (TEM) was used to examine the morphology of liposomes. Its actions to inhibit hepatitis B virus HBsAg and HBeAg secreted was studied by a HBV-transfectted cell line (HepG2 2. 2. 15 ).

RESULTSEncapsulation efficiency of liposomes by chloroform:methanol (2:1, v/v) was higher than that by dioxane. With the increase of the ratio of nosiheptide: PC (W/W), the encapsulation efficiency of liposomes decreased with the increase of ratio of sodium deoxycholate: PC, the liposomes partical size decreased. The liposomes kept stable at -20 degrees C after 2 years. The drug concentrations of liposomes that inhibit HBsAg secreted by (46.9 +/- 2. 6) %, (55.4 +/- 1.2) %, (65 +/- 3) % and HBeAg secreted by (15.1 +/- 2.3) %, (36.2 +/- 1.7) %, (36.8 +/- 2.5) % were 1.25, 2.5, 5.0 microg x mL(-1), respectively.

CONCLUSIONLiposomes of nosheptide can be prepared by sodium deoxycholate dialysis and sonication, which ability to inhibit hepatitis B virus HBsAg and HBeAg secreted is better than nosheptide.

OBJECTIVETo compare the clinical efficacy on upper limb motor impairment in stroke between the interactive dynamic scalp acupuncture therapy and the traditional scalp acupuncture therapy.

METHODSThe randomized controlled trial and MINIMIZE layering randomization software were adopted. Seventy patients of upper limb with III to V grade in Brunnstrom scale after stroke were randomized into an interactive dynamic scalp acupuncture group and a traditional scalp acupuncture group, 35 cases in each one. In the interactive dynamic scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (anterior oblique line of vertex-temporal), the middle 2/5 of Dingniehouxiexian (posterior oblique line of vertex-temporal) and Dingpangerxian (lateral line 2 of vertex) on the affected side were selected as the stimulation areas. Additionally, the rehabilitation training was applied during scalp acupuncture treatment. In the traditional scalp acupuncture group, the scalp stimulation areas were same as the interactive dynamic scalp acupuncture group. But the rehabilitation training was applied separately. The rehabilitation training was applied in the morning and the scalp acupuncture was done in the afternoon. The results in Fugl-Meyer for the upper limb motor function (U-FMA), the Wolf motor function measure scale (WM- FT) and the modified Barthel index in the two groups were compared between the two groups before treatment and in 1 and 2 months of treatment, respectively.

RESULTSAfter treatment, the U-FMA score, WMFT score and the score of the modified Barthel index were all apparently improved as compared with those before treatment (all P < 0.01). The improvement in the U-FMA score after treatment in the interactive dynamic scalp acupuncture group was better than that in the traditional scalp acupuncture group (P < 0.05). For the patients of IV to V grade in Brunnstrom scale, WMFT score in 2 months of treatment and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were improved apparently as compared with those in the traditional scalp acupuncture group (P < 0.05, P < 0.01). But, for the patients of III grade in Brunnstrom scale, WMFT score and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were not different significantly as compared with those in the traditional scalp acupuncture group (both P > 0.05).

CONCLUSIONFor the patients of IV to V grade in Brunnstrom scale in stroke, the interactive dynamic scalp acupuncture therapy achieves the superior improvements of the upper limb motor function and the activity of daily life as compared with the traditional scalp acupuncture therapy, and the longer the treatment lasts, the more apparent the improvements are. For the patients of III grade in Brunnstrom scale, the interactive dynamic scalp acupuncture therapy achieves the similar improvement in the upper limb motor impairment as compared with the traditional scalp acupuncture therapy.

BACKGROUND: Osteoporosis is a genetic disease associated with many enes. To date, the genes that regulate bone mass are incompletely defined.OBJECTIVE: To investigate the relationship between polymorphisms of steoprotegerin (OPG) gene promoter with bone mineral density (BMD) in remenopausal and postmenopausal women.DESIGN: Prospective study.SETTING: Peking Union Medical College Hospital.PARTICIPANTS: In July 2002, 495 Han nationality women selected from Peking Union Medical College Hospital were non-related volunteers and gave their informed consent prior to the study, which included 306 premenopausal women aged 20-39 years, 189 postmenopausal women aged 50-84 years.METHODS: ① BMD measurement: BMD was measured at the Lumbar Spine and Femoral Neck, trochanter, Ward's triangle by dual-energy X-ray absorptiometry. ② Genotyping: Whole blood genome DNA was extracted by QIAGEN DNA extraction kit. The PCR product and the result of endonuclease digest were confirmed by sequencing (Bioasia Biotechnology,Shanghai, China). The impact of the polymorphisms on BMD was also investigated using multiple Logistic regression.MAIN OUTCOME MEASURES: ① Distribution of OPG genotypes and the relationship with BMD. ② Association between OPG polymorphisms and osteoporosis.RESULTS: All 495 subjects were involved in the final analysis. ① These polymorphisms were in Hardy-Weinberg equilibrium (χ2= 0.056 -0.222, P＞ 0.05). The frequencies of genotypes of these subjects were as follows: AA (70.1%), AG (26.9 %), GG (3.0 %) for 163A→G polymorphism; TT (71.3 %), TG (25.9 %), GG (2.8 %) for 245T→G polymorphism. BMD was lower in premenopausal women with GG +AG genotype than AA genotype for 163A→G polymorphism, so did GG+TG genotype than TT genotype for 245T→G polymorphism. But there was no significant difference. BMD was lower in postmenopausal women with AG+GG genotype than AA genotype for 163A→G polymorphism at Lumbar Spine 2-4, Femoral Neck, Ward's triangle and Trochanter (P ＜ 0.05). For 245T→G polymorphism, BMD of postmenopausal women with TG+GG genotype was lower at Femoral Neck,Ward's triangle and Trochanter than TT genotype (P ＜ 0.05). For 245T→G polymorphism, BMD of postmenopausal women with TG+GG genotype was lower at Femoral Neck, Ward's triangle, and Trochanter than TT genotype (P ＜ 0.05). ② Age, weight, height, years since menopause, and 163A→G/245T→G genotypes were sewed as covariates. AG+GG genotype was contributed to low BMD at Lumbar Spine 2-4 and Ward's triangle (OR =2.045, OR=2.956, P ＜ 0.05, 95% CI 1.05-6.7). TG+GG genotype was risk factor for osteoporosis at Lumbar Spine 2-4, Ward's triangle,and Trochanter (OR=2.059, OR=2.859, OR=2.123, P ＜ 0.05, 95% CI 1.04-6.5).CONCLUSION: BMD was lower in postmenopausal women with the variant G allele for 163A→G and 245T→G polymorphisms at Femoral Neck,Ward's triangle, and Trochanter. The variant allele G may associate with lower BMD in postmenopausal women.

OBJECTIVETo study a method for extraction and analysis of volatile components from Chrysanthemum morifolium 'gonghuangjv' cv. nov (CM GHJ) and C. morifolium 'gongbaijv' cv. nov (CM GBJ) by solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS).

METHODThe volatile components were extracted in different temperature, different balance period and different extraction fiber using head space solid-phase microextraction (HS-SPME), and were identified by CGC-MS. The variety in integral area of each component was observed in different conditions and its relative content was determined by normalization of area.

RESULTThe better condition of SPME for C. morifolium was that the sample was extracted using 100 microm polydimethylsiloxane (PDMS) extraction fiber after it had been balanced for 6 hours at 75 degrees C. 53 components from CM GHJ and CM GBJ were identified, and there were 35 same components in CM GHJ and CM GBJ.

CONCLUSIONHS-SPME-GC-MS is convenient, rapid and reliable for analysis of volatile components in C. morifolium.
