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”.

Objective To study a nucleic acid extraction method suitable for detecting methicillin‐resistant Staphylococcus aureus (MRSA) by PCR method .Methods Under different incubation conditions ,MRSA was cracked by lysozyme ,lysostaphin or chel‐ex100R resin for obtaining DNA ,then the target gene was detected by using the PCR method .Results DNA was obtained by sim‐ultaneously using lysozyme ,lysostaphin and chelex100R resin solution ,the obtained Ct value was significantly lower than that of the other components of schizolysis solutions when PCR was used to detect mecA gene of obtained DNA .There was no statistically sig‐nificant difference between adopting the 56 ℃ one‐step method and the 37 ℃ and 56 ℃ two‐step method for conducting MRSA schizolysis(P> 0 .05) ,but the steps were simplified .Conclusion Incubating MRSA in solution containing lysozyme ,lysostaphin , chelex100R resin for 30 min at 56 ℃ is the convenient and efficient schizolysis method to extract DNA ,which can be used immedi‐ately for the next step of PCR and lays the foundation for PCR rapid detection of clinical MRSA infection .

Objective To study the status of mouse fetal transgenic cells existed in the maternal blood in peri-natal period and provide the information for gene diagnosis using fetal cells circulated in the maternal blood.Methods Mating the female normal mice with male transgenic mice integrated with GFP reporter gene driven by ?-globin promoter and HS2-HS3 elements of LCR. Around the offspring were born, maternal blood was collected and GFP expression level was determined with FACS analysis. Meanwhile, DNA extracted from the tails of the mothers and their offspring as well as the maternal blood were analyzed by PCR.Results GFP positive fetal cells were not found in maternal blood before offspring were born. 1-3 weeks later, GFP positive fetal cells were detected and this population in maternal peripheral blood reached the peak. 4-5 weeks later, they disappeared gradually. PCR results showed no GFP positive band in the mothers. However, a positive fragment of GFP gene was amplified in maternal blood samples after their offspring were born. This result was in accordance with FACS analysis.Conclusion Transgene cells may be useful markers for the study of status of fetal cells existed in the maternal circulating blood. The results would be beneficial for the gene diagnosis using maternal blood as an alternative resource of fetal cells.

Objective: To investigate the clinical efficacies of fire acupuncture in treat various types of acne. Methods: An open test was designed. One thousand and eighty-six patients who visited for clinical service were collected as a sample. Results: The cure and marked effective rate was 78.5% for lung heat type, 80.8% for heat toxin type, 77.4% for disharmony of the Thoroughfare and Conception Vessels type and 80.1% for blood stasis and phlegm accumulation type. Statistical analysis showed no significant differences in therapeutic effect between different types (P>0.05). Conclusion: Fire acupuncture has an exact therapeutic effect on various types of acne without toxic side effects.

Biotrickling filter often offers a cost effective and environmentally friendly alternative to conventional air pollutant control technologies,but major problems with clogging of the filters due to a high biomass accumulation will provent it from the industried uses.In this paper,the effect of the high biomass accumulation in an air pollution treatment with a biotrickling filter is discussed.Two parameters with specific surface area with biofilm growth(?_ f ) and the bed porosity with biofilm(?_ f )are used to analyse its principle of accumulation.Finally,some control measures including chemical methods,physical machine-made methods and other control methods are overviewed.

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.

BACKGROUND: Coffee is commonly consumed among young people in China. However, consumers are rarely aware of physicaly adverse effects as a result of excessive consumption of caffeine. DATA SOURCES: A literature search using multiple databases was performed for articles published with concentration on meta-analyses, systematic reviews, and randomized controlled trials. RESULTS: Excess coffee consumption is also a risk of primary cardiac arrest especially in young people. Treatment modalities include activated charcoals, beta-blockers, vasopressin and hemodialysis when necessary. CONCLUSION: Coffee consumers should be advised not to routinely take more than moderate coffee.

AIM:To investigate the changes of connexin 43 (Cx43) via establishing a model of sympathomi-metic atrial fibrillation ( AF) .METHODS:The mongrels ( n=15) were randomly divided into control group , rapid atrial pacing (RAP) group and isoprenaline (ISO) perfusion+RAP group (ISO+RAP group).All mongrels’ hearts were taken out rapidly by median sternotomy to establish the cardiac model with Langendorff perfusion in vitro.The atrial effective re-fractory period ( AERP) and AF inducability were tested .The expression and distribution of tyrosine hydroxylase ( TH) were analyzed by immunohistochemistry .Total protein level of Cx 43 and phosphorylation of Cx 43 were determined by West-ern blot.The distribution of Cx43 were also observed by immunofluorescence staining .The cell apoptosis was analyzed by TUNEL staining.The generation of reactive oxygen species ( ROS) in the mitochondria was measured by fluorescence spec-trophotometry .RESULTS:No significant change of AERP was found between control group and RAP group , while that in ISO+RAP group was significantly decreased (P<0.05) and induced AF.Compared with control group, the expression of TH, apoptotic index and the generation of ROS increased gradually (P<0.05), while the content of Cx43 decreased grad-ually both in the total protein and the phosphorylation levels in RAP group and ISO +RAP group (P<0.05).The fluores-cence intensity of Cx43 was also attenuated and Cx43 were lateralized apparently in RAP group , while Cx43 were character-ized as punctate distribution in ISO +RAP group.CONCLUSION:Sympathetic nerves may activate autophagosome at in-tercalated discs and trigger cell apoptosis , resulting in remodeling and downregulation of Cx 43 via oxidative stress , thus having effects on mediating and maintaining AF .

Erectile dysfunction is common complication of diabetes mellitus. The incidence of diabetes mellitus induced erectile dysfunction (DMED) is 20% - 75%. DMED appears to be due to vascular-neuropathic and corpus cavernosum smooth muscular damage. To control blood glucose, blood pressure and blood lipids is the basis of DMED therapy. In 50% of the patients with DMED, the phosphodiesterase 5 inhibitors is effective, while intracavernous pharmacotherapy is effective for more than 90%. Penile prosthesis implantation continues to be the treatment of choice in case of other therapy failure.
