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.

Objective To investigate bone mineral density ( BMD ) after filling in the bone scaffolds with anti-tuberculosis controlled-release microspheres, and provide experimental basis for decrease of the side effects of anti-tuberculosis therapy after spinal surgery.Methods The bone densitometer was used to observe the changes of bone mineral density before and after the infusion with the artificial allograft bone (Group A), the controlled release complex of the RFP controlled-release microspheres-artificial allograft bone (Group B), and RFP-artificial allograft bone complex (Group C), respectively.Results BMDs of three groups before perfusion were not different significantly [Group A:(0.191 ±0.018)g/cm2;Group B:(0.186 ±0.016)g/cm2;Group C:(0.189 ±0.018)g/cm2;P >0.05].BMDs of three groups after perfusion were not different significantly [Group A:(0.191 ±0.018)g/cm2;Group B:(0.179 ±0.023)g/cm2;Group C:(0.185 ±0.021)g/cm2;P >0.05].Conclusions RFP microspheres using ultrasonic vibration method and the porous bone were prepared to controlled-release anti-tuberculosis complex .BMD of three groups after perfusion were not influenced obviously .

ObjectiveTo evaluate the efficacy about the different wearing manner with Milwaukee and Boston for the treatment of adolescent idiopathic scoliosis (AIS).MethodsRetrospectively summarization and analysis was performed in 85 adolescent patients with idiopathic scoliosis who were treated from February 2004 to March 2009.The skeletal growth of them had not completed.There were 57 cases who received brace treatment.In them,28 were treated with (CTLSO) Milwaukee brace,and the rest were treated with (TLSO) Boston brace and orthopedic gymnastics.The 30 cases wear regularly used for 21 to 23hours per day,and 27 cases could consist on wearing only 6 to 15 hours per day.The other 28 cases of 85AIS cases were only treated with orthopedic gymnastics instead of orthosis treatment.All patients were periodically observed with lateral side (X)-ray photograph at standing position and photograph,and Cobb angle and Risser sign were measured every 3 to 6 months.Since 2008 all adolescent idiopathic scoliosis patients treated with orthosis were requested to fill with simplified Chinese SRS-22.Results73 cases adolescent idiopathic scoliosis patients were followed up for 2 ～5 years [ mean(26.3 ± 33.7)months ].Milwaukee orthosis group showed the regular wearing group had 91.67 ％ ( 11/12) effective rate and the intermittent wearing group had 56.25％ (9/16) effective rate and the group without wearing orthosis only had 20％ (4/20)effective rate.The group regularly wearing Milwaukee brace had superior effect than the other two groups (P ＜ 0.05 ).Boston orthosis group showed the regular wearing group had 88.89％ (16/18) effective rate and the intermittent wearing group had 54.55％ (6/11 ) effective rate and the group without wearing brace with 25％ (2/8) effective rate.The group regularly wearing Boston brace had better effect than the other two groups ( P ＜ 0.05 ).Due to the different choice of AIS patients and orthosis,the effective rate of the Milwaukee and Boston orthosis was not compared.ConclusionsThe adolescent idiopathic scoliosis patients should insist on regularly wearing brace regardless of the Milwaukee or Boston orthosis ( this article suggest that the wearing time should not less than 21 ～ 23 h/d).The group regularly wearing with the Milwaukee or Boston orthosis had better effect than the intermittent group or the group without wearing brace.It's a good treatment for the AIS patients who have with the indication of orthosis treatment.

Neuritin is a new neurotrophic factor found recently. In order to identify the function of Neuritin clearly, the coding sequence of human neuritin was amplified by PCR from neuritin cDNA , this fragment digested by NocI and NotI was inserted into pET32a by T4 ligase and transformed into E. coli BL21 then the recombinant plasmid named pET32a-neuritin was constructed successfully . Neuritin was expressed distinctly after inducing by EPTG. The product was identified as neuritin by SDS-PAGE and Western blot analysis . The expression production was purified on Ni2+-NTA column.

OBJECTIVETo analyze the existence and the dynamic cell frequencies of human cells in goats transplanted in utero with human hematopoietic stem cell (hHSC) by using fluorescence in situ hybridization (FISH) technique.

METHODSInterphase FISH (IFISH) with human-specific 17-chromosome satellite DNA and/or human-specific Y-chromosome satellite DNA as probes was performed to analyze the presence and proportions of human cells in 13 transplanted goats. Samples were peripheral blood cells, bone marrow smears and liver touch imprint preparations.

RESULTSOf the 13 transplanted goats, eleven were identified to present human cells. Among them, two goats transplanted with human male HSC were found to have human male cells. The results demonstrated that these transplanted goats were human/goat HSC xenogeneic chimeras. Human cell frequencies decreased with the goat age (months), but the longest survival reached 21 months. During the detected life periods of goats, human cell frequencies in peripheral blood, bone marrow and liver tissues were less than 1@1000, but local human cell frequencies of 207.92@1000 and 392.41@1000 were detected in the liver tissues of 2 transplanted goats.

CONCLUSIONSThe existence and long-term survival of human cells in transplanted goats detected by FISH indicated that goats were appropriate recipients for hHSC in utero transplantation. The lower human cell frequencies in blood and bone marrow, and the higher local human cell frequencies in liver tissues suggested that the microenvironment of goat liver tissues might favor the survival, proliferation and differentiation of human cells.

Objective　To explore the relationship between hemolymph phenol oxidase and the melanization of Plasmodium yoelii oocysts in Anopheles dirus. Methods　An Anopheles dirus-Plasmodium yoelii system was used Anopheles dirus were divided into 3 groups, that is, non-blood-fedding (N), normal-blood-fedding (B) and infected-blood-fedding (I). The activities of MPO and o-DPO in hemolymph from 3 groups were determined with native polyacrylamide gel electrophoresis (PAGE) and density scanning at 5, 7, 11 and 15 d after blood feeding. Results　Both MPO and o-DPO activity were significantly higher in group I than group N and B (P<0.05). But with the melanization of Plasmodium yoelii oocysts, both MPO and o-DPO activity in group I were decreased in comparison with group N, especially on the 15 th day after infected-blood feeding. MPO and o-DPO activity in group B were significantly stronger than those of group N. Conclusion　Blood feeding and infection of Plasmodium yoelii both can activate the cascade. The heamolymph phenol oxidase may play an important role in the melanization of Plasmodium yoelii oocysts in Anopheles dirus.

Objective To investigate the clinical efficacy of electroacupuncture plus indirect moxibustion treating lumbar intervertebral disc herniation of blood stasis type. Method Sixty patients diagnosed with lumbar intervertebral disc herniation (blood stasis type) were randomized to treatment and control groups, 30 cases each. The treatment group received electroacupuncture plus medicine separated moxibustion and the control group, electroacupuncture alone. treatment was given once daily, 10times as a course. Pre- and post-treatment JOA lumbar scores were compared in the patients after two courses of treatment. The clinical therapeutic effects were evaluated in the patients using the TCM Criteria of the Diagnosis of and Therapeutic Effect on Diseases. Result Lumbar function was improved significantly in both treatment and control groups of patients (P<0.01) but improved more significantly in the treatment group than in the control group (P<0.05). The total efficacy rate was 96.7% in the treatment group and 83.3% in the control group. There was a statistically significant difference in the total efficacy rate between the two groups (P<0.05). Conclusion Electroacupuncture plus indirect moxibustion is a better way to treat lumbar intervertebral disc herniation of blood stasis type. Its therapeutic effect is better than that of electroacupuncture alone.

Objective To observe the effects of comprehensive measures of changing grain,selenium supplementation,off-site education and resettlement on prevention of children's Kashin-Beck disease in Aba state.Methods Fifty eight villages in Aba Kashin-Beck disease areas were chosen as intervention points in Aba state Sichuan province from 2007 to 2011.Based on the implementation of prevention and control measures,the villages were divided into off-site education + changing grain + selenium supplementation group and resettlement + off-site education + changing grain + selenium supplementation group,Geletuo town of Seda county,Ganzi state was selected as a control point,and right-hand anteroposterior X-ray examination(including the wrist) was carried out on children aged 6-13 from 2007 to 2011 annually.Clinical and X-ray diagnosis of Kashin-Beck disease was made in accordance with the Diagnostic Criteria of Kaschin-Beck Disease(GB 16003-1995).The effects of prevention and control measures were evaluated by comparing the child X-ray detection rate before and after the implementation of the measures.Results The average X-ray positive detectable rate of children in the intervention points was 2.07％(66/3181),2.72％ (69/2540),1.16％ (35/3017),0.56％ (19/3397) and 0.56％ (24/4273),respectively from 2007 to 2011,with a downward trend (x2trend =66.74,P ＜ 0.01).There was a downward trend in the average X-ray positive detectable rate of children in off-site education + changing grain + selenium supplementation group [1.60％(29/1809),2.63％ (39/1484),1.29％ (25/1941),0.64％ (15/2332),0.42％ (10/2379)] and resettlement + off-site education + changing grain + selenium supplementation group [2.70％ (37/1372),2.84％ (30/1056),0.93％(10/1076),0.38％ (4/1065),0.74％(14/1894)] (x2trend=30.97,35.19,all P ＜ 0.01).The average X-ray positive detectable rate of children in the intervention group was 0 from 2007 to 2010,and was 1.61％ (1/62) in 2011.The difference of X-ray positive detectable rate was not statistically significant in the control group in the 5 years from 2007 to 2011.The difference of children's X-ray positive detectable rate was not statistically significant between control group and intervention group.Conclusions The effect of taking changing grain,selenium supplementation,off-site education and resettlement comprehensive measures to prevent children's Kashin-Beck disease is not significant in those places where the state of Kaschin-Beck disease is not active.

Objective To evaluating the effectiveness of comprehensive measures to control the plague in epidemic areas in Longlin county Guangxi from 2001 to 2010.Methods Original epidemic places was deratised,indicative animals were investigated,and epidemic clues were searched.Cage trapping method was used to capture rat and rat body fleas were collected in the plague epidemic areas.The flea-carrying rates and flea index of rodents were calculated based on the number of fleas collected from caged rodents.The animals were then subjected to etiological and serological tests to determine the plague infection rate.Results A total of 1008 rats were captured and 571 fleas were collected from 2001 to 2010,of which Rattus Flavipestus accounted tor 81.65％(823/1008) and Xenopsylla Cheopis for 64.10％(366/571).The annual average rodents infected with flea and the index of flea were 23.02％ (177/769) and 0.74,respectively.The annual average density of rodents decreased from 3.99％ (859/21 508,before deratised) to 0.96％ (149/15 600,after deratised).The deratization rate was 75.94％.Conclusion The risk of a plague epidemic in Longlin county is reduced after continued comprehensive measures be taken to deal with the disease.
