Most of the transfusion adult outpatients are old people with chronic disease, and theirsmall blood vessels become less elastic with age. They need long course and repeated localised puncture site. On the base of that fact, the author describes the 5.5gauge scalp acupuncture and 7 gauge scalp acupuncture about their use on the patients. The 5.5 gauge scalp acupuncture is smaller and shorter, so it has the advantage of high success ratio and it is easier to be fixed. Additionally, the transfusion speed is easy to be controlled, which reduces the ratios of transfusion reaction and adverse drug reactions. The pinhole is small and can be healed faster. The congestion around the puncture location is less than that of the 7 scalp acupuncture. It can alleviate the pain for patients and increase satisfaction. To sum up, the 5.5 gauge scalp acupuncture should be used widely as we allocate“people oriented”and“All for the patients”.

The effects of solid-state fermentation (SSF) and submerged fermentation (SmF) and the addition of olive oil on the whole-cell lipase production by Rhizopus chinensis CCTCC M201021 were investigated.Compared with SSF, higher biomass, hydrolytic activity and synthetic activity were observed in SmF.By the addition of olive oil, the synthetic activity of whole-cell lipase in both fermentations was enhanced significantly, especially in SmF, while the biomass and the hydrolytic activity were also increased.Hence, olive oil serves as both carbon source and the inducer of lipases in fermentation.It was also found that the synthetic activity of whole-cell lipase was not accordant to the hydrolytic activity during both SmF and SSF, suggesting that isoenzymes with difference in lipase properties may be produced by Rhizopus chinensis.

Objective To investigate the expression and correlation of hypoxia-inducible factor-1?(HIF-1?),vascular endothelial growth factor(VEGF)and sFlt-1 in the preeclampsia placenta,and discuss their significance in the pathogenesis of preeclampsia.Methods Placentas were collected from 20 pregnant women with preeclampsia as study group and 15 normal pregnant women as control group.The expressions of HIF-1?,VEGF and sFlt-1 protein were semi-quantitatively analyzed with immunohistochemical assay and mRNA level was determined using reverse transcription polymerasc chain reaction(RT-PCR)technique. Results(1)the expression of HIF-1?and sFlt-1 protein in preeclampsia group obviously increased.Strong (+++)positive expression was observed in 9 and 11 cases respectively,significantly higher than in control group(2 and 3 cases)(P＜0.05),however,VEGF expression obviously reduced in preeclampsia group(P＜0.01).(2)the level of HIF-1?and sFlt-1 mRNA in preeclamptic placenta was 0.604?0.013, 0.898?0.041,significantly higher than 0.208?0.007 and 0.559?0.244 in normal placenta(P＜0.05). Although the level of VEGF mRNA increased in preeclampsia placenta,it was not significantly different from that in normal placenta(P＞0.05).The ratio of VEGF mRNA/sFlt-1 mRNA obviously reduced in preeclampsia group and was significantly lower than in control group(P＜0.05).(3)in preeclampsia group,HIF-1?mRNA expression was positively correlated with the expression of sFlt-1 mRNA(r=0.577, P＜0.05),and negatively correlated with the ratio of VEGF mRNA/sFlt-1 mRNA(r=-0.376,P＜0.05).Conclusion Abnormal high HIF-1?expression in preeclampsia placenta indicates that HIF-1?might play an important role in the pathogenesis of preeclampsia,possibly through affecting the cytotrophoblastic invasion and placental vascular reconstruction via the modulation of VEGF and sFlt-1 gene transcription.

Background In previous study,peripheral retinal nerve fiber layer (RNFL) thickness is considered to be the earliest structural changes which can be detected.3D-OCT can measure the thickness of macular ganglion cell complex (mGCC),which makes the detection of primary glaucoma possible in the early stage.Objective This study was to measure the thickness of mGCC and disc-peripheral RNFL in early stage of primary glaucomous eyes by 3D-OCT and assess the anatomic basis of glaucoma-induced optical nerve damage.Methods 3D-OCT images from 10 patients with advanced stage primary glaucoma in one lateral eye and early stage glaucoma in fellow eye from December 2010 to December 2012 were prospectively analyzed in China-Japan Friendship Hospital.The patients were diagnosed based on the recommended standard of National glaucoma group (1987 version) and received routine eye examination.3D-OCT scanning was performed using 3D-macular mode,3D-macular Wide mode and 3D-disc mode with TOPCON 3D-OCT 2000 system,and the images at macular 6 mm×6 mm area were analyzed.The posterior pole area was divided into 5 concentric rings from fovea toward periphery and equally subdivided into 100 small checks,with the area of 0.6 mm×0.6 mm for each.The probable values in each check were calculated as the ratio of each figure and corresponding normal value.The probable values were expressed as red color (P＜ 1％),yellow color (P＜5％) and gray color (P≥ 5％).Then the disc-periphery RNFL thickness and disc cup were evaluated.Results No evident abnormality was found in the thicknesses of photoreceptors layer and bipolar cell layer in both advanced glaucomous eyes and the early stage of glaucomous eyes in the 10 patients.Serious damage of visual field was seen in the advanced glaucomous eyes and presented with red color in the parapapillary RNFL area,mGCC area and macular RNFL area,showing an evidently attenuation of the thicknesses of parapapillary RNFL,mGCC and RNFL.However,the visual field was close normal in the early stage glaucomous eyes,and mGCC and macular RNFL showed yellow color,while green or yellow color was exhibited in the parapapillary RNFL area,indicating mGCC and macular RNFL thickness was reduced,but parapapillar RNFL thickness was near normal.Conclusions The change of mGCC thickness is earlier than that of peripheral RNFL at optic disc in primary glaucomaous eyes,which may imply that the disappear of macular ganglion cell body is earlier than that of the axon.

OBJECTIVE To investigate the feasibility of endoscopic sinus surgery under local anesthesia.METHODS A total of 810 patients underwent endoscopic sinus surgery from January 2000 to December 2007 with complete follow-up data were included in this study.Validity of anesthesia was evaluated using VAS(visual analogous scale).Operation time,bleeding quantity during operation,operation therapeutic efficacy,hospitalization cost and patient's evaluation to the operation were recorded.RESULTS The mean VAS score of local anesthesia was 3.18?0.46.Cases with no pain and mild pain accounted for 78.28%,with moderate pain 16.71%,and with severe pain 5.01%.The average bleeding quantity during operation,operation time,complication incidence,cure rate at 6 months after operation,hospitalization cost,patients' evaluation in local anesthesia were(43.25?27.46)ml,(41.14?9.479) min,1.78%,78%,4000～6000 yuan(RMB),9.28? 2.21 respectively.CONCLUSION For the endoscopic sinus surgery,most cases can be operated under local anesthesia if the indication were selected correctly and the sophisticated skills and advanced instrument were available.

Objective To observe the effect of bacillus bifidus preparation on the prevention of gastrointestinal side effects in children with acute lymphocyte leukemia (ALL) during high-dose methotrexate (HD-MTX) chemotherapy.Methods One hundred and fifty-two ALL children were randomly assigned into 2 groups according to the suggestion of diagnosis and treatment of ALL in childhood.There were 76 patients in each group.In the treatment group,there were 46 male and 30 female,aged 2 to 13 years old (the median age was 8 years).While in the control group,there were 41 male and 35 female (the median age was 8.2 years).They were treated with the same chemotherapy schedule (HD-MTX),supportive therapies and infection preventive measures.ALL children in the treatment group were additionally given the bacillus bifidus preparation (one tablet for 2 to 6 years old,and two tablets for 7 to 15 years old,3 times daily),if their WBC was more than 2.0?109 L-1.Those in the control group were given vitamin B complex tablets (one tablet for 2 to 6 years old and two tablets for 7 to 15 years old,3 times daily).Results ALL children in treatment group had less diarrhea,abdominal pain,nausea and vomiting,or liver function impairment induced by chemotherapy than those in control group.However,the bacillus bifidus preparation had no significant effects on the symptoms of fever and oral mucosal erosions in the period of chemotherapy.Conclusion The bacillus bifidus preparation is clinically useful for the prevention of gastrointestinal side effects associated with HD-MTX chemotherapy.

Objective To investigate the effects and mechanisms of 1,25-Dihydroxyvitamin D3 [1,25(OH)2 D3] on hyperoxia-induced lung injury of neonatal rats.Methods Neonatal Sprague-Dawley rats were randomly divided into air group,hyperoxia group and 1,25(OH)2D3 group within 12 hours after birth,eight in each group.Rats in air group were exposed to air,while those in hyperoxia and 1,25 (OH) 2 D3 group were exposed to hyperoxia (≥85 ％ oxygen concentration).Rats in 1,25(OH)2D3 group were injected with 1,25(OH)2D3 0.5 μg/(kg · d) intraperitoneally once a dayfor seven days,meanwhile the rats in the other two groups received 0.9 ％ saline in the same way.All rats were sacrificed on day 7.Lung tissue sections were HE stained in order to assess lung histological changes and lung radical alveolar count (RAC).The levels of tumor necrosis factor-α(TNF-α),interleukin(IL)-1β and IL-6 mRNA were measured by real time-polymerase chain reaction.Analysis of variance and LSD test were applied for statistics.Results Compared with the air group,the weight of rats in the hyperoxia group was significantly lower on day 7 [(8.48±1.34) g vs (12.51±0.47) g,t=8.05,P＜0.05],while the weight of rats in 1,25(OH)2D3 group [(10.29±1.00) g] was higher than that in the hyperoxia group (t=3.61,P＜0.05).Lung tissue structure was normal in the air group.In the hyperoxia group,inflammatory exudation was observed in pulmonary interstitial,the alveolar size was uneven,and the RAC was lower than that in the air group (5.6±0.1 vs 6.8±0.2,t=21.45,P＜0.05).The RAC in 1,25(OH)2D3 group (6.2±0.1) was significantly increased compared with that in the hyperoxia group (t=11.76,P＜0.05),but still lower than that in the air group (t=9.69,P＜0.05).The expressions of TNF-α,IL-1β and IL-6 mRNA in hyperoxia group (0.0348±0.0006,0.0269±0.0003 and 0.0368 ± 0.0006) were higher than those in the air group (0.0111±0.0007,0.0040±0.0003 and 0.0162 ±0.0007,t=56.54,111.12 and 49.26,P＜0.05,respectively).The expressions of TNF-α,IL-1β and IL-6 mRNA in the 1,25 (OH)2D3 group (0.0203±0.0009,0.0141±0.0004 and 0.0251±0.0009) were lower than those in the hyperoxia group (t=34.44,61.93 and 27.99,P＜0.05,respectively),but higher than those in the air group (t=22.10,49.19 and 21.27,P＜0.05,respectively).Conclusions 1,25(OH)2D3 could attenuate hyperoxia-induced lung injury by inhibiting the expression of inflammatory cytokines.

Quercetin and its glycosides are important flavonols in traditional herbal drugs and plant-derived food, and they have diverse hiological activities such as antioxidant, anticarcinogenic, anti-inflammatory, hypoglycemic and hypolipidemic activities. Numerous studies have demonstrated that quercetin and its glycosides were effective in the prevention and treatment of non-infectious chronic disease such as diabetes, obesity, and hyperlipidemia. They can regulate glucose and lipid metaholism through different mechanisms. They can decrease blood glucose via protecting pancreatic/p cells or/and improving insulin sensitivity. Also, they have lipid-lowering effects, which may be the result of regulation of lipid catabolism or/and anabolism. Their distributions, as well as the hypoglycemic and hypolipidemic effects are reviewed in this paper. In addition, further bioactivities as well as their dose-activity relationship, structure-activity relationship, bioavailability, and future clinical application of quercetin and its glycosides are discussed and proposed.
