Objective] The pathogenesis of HuangQin Tang is discussed little in six meridians syndrome differentiation, and which meridian syndrome does it belong to isn’t clear. So this article tries to discuss the belonging and pathogenesis of it. And the key point of using it in clinic will also be involved.[Method] Combining the observation of efficacy of XiaoChaiHu Tang and HuangQin Tang and the elaboration articles are related to that two prescriptions to analyze the difference of that two prescriptions in pathogenesis.[Result]It’s found that HuangQin Tang and XiaoChaiHu Tang all belong to ShaoYin in six meridian syndrome.But their pathogenesis is different. HuangQin Tang should be used in heat syndrome of ShaoYang disease which caused by heat pathogen of ShaoYang meridian and diarrhea will appear because belly is shocked. However, XiaoChaiHu Tang is used to drive cold pathogen of ShaoYang meridian. [Conclusion]Both of HuangQin Tang and XiaoChaiHu Tang belong to ShaoYang Meridian, but it’s known that HuangQin Tang is used less. And less discussion of HuangQin Tang should be blamed. The more we know on pathogenesis of HuangQin Tang, the better we use it.

Multislice Cr angiography represents one of the most exciting technological revolutions in cardiac imaging and it has been increasingly used in the diagnosis of coronary artery disease.Rapid improvements in multislice CT scanners over the last decade have allowed this technique to become a potentially effective alternative to invasive coronary angiography in patients with suspected coronary artery disease.High diagnostic value has been achieved with multisfice CT angiography with use of 64-and more slice CT scanners.In addition,multislice CT angiography shows accurate detection and analysis of coronary calcium,characterization of coronary plaques,as well as prediction of the disease progression and major cardiac events.Thus,patients can benefit from multislice CT angiography that provides a rapid and accurate diagnosis while avoiding unnecessary invasive coronary angiography procedures.The aim of this article is present an overview of the clinical applications of multislice CT angiography in coronary artery disease with a focus on the diagnostic accuracy of coronary artery disease;prognostic value of coronary artery disease with regard to the prediction of major cardiac events; detection and quantification of coronary calcium and characterization of coronary plaques.Limitations of multislice Cr angiography in coronary artery disease are also briefly discussed,and future directions are highlighted.

Objective To analyze the detection rate of neonatal congenital malformation,and to explore the risk factors for neonatal malformation.Methods A total of 29 831 infants born in Shenzhen People's Hospital from January 2011 to December 2015 were analyzed retrospectively,the detection rate of congenital malformations was calculated,381 infants with congenital malformation were selected as malformation group,and 381 healthy infants were selected as healthy control group,and the risk factors of congenital malformation were analyzed.Results A total of 381 infants with congenital malformation were screened out,the incidence rate of congenital malformation being was 12.77‰(381/ 29 831 cases).The incidence rates of multi-finger or multi-toe,cleft lip,congenital heart disease were the high,which were 18.64％ (71/381 cases),17.32％ (66/381 cases) and 16.80％ (64/381 cases),respectively.The multiple Logistic analysis showed that birth children with low weight newborns (＜ 2 500 g),multiple births,preterm birth (＜ 37 weeks),pregnancies ＞ 1,low literacy levels of mothers,living in towns,late childbirth (≥ 35 years of age),pregnancy syndrome,viral infection during early pregnancy,medication history during pregnancy,rubella unvaccinated,exposure to harmful substance,smoking and alcohol during pregnancy and paternal smoking,chronic diseases,total 16 items were related risk factors for neonatal congenital malformations (all P ＜ 0.05).Among them,the impact of viral infection during early pregnancy,alcohol,smoking,pregnancy syndrome,exposure to harmful substance,medication history during pregnancy on the incidence of malformations in neonates was relatively serious.Conclusions The incidence rate of congenital malformations among neonates conforms to the present situations in China,which was closely correlated with genetic and environmental factors.Health education targeting pregnant women and the women of childbearing age should be carried cut to reduce the birth of neonatal congenital malformations.

ObjectiveTo investigate the effect of heart-regulating and mind-calming acupuncture on the expression of gap junction protein connexin43 (Cx43) in myocardial cells in a rabbit model of ventricular arrhythmia.MethodA rabbit model of ventricular arrhythmia was made by injecting barium chloride into the marginal ear vein. Forty New Zealand rabbits were randomized into control, model, acupuncture and medication groups. The acupuncture group received heart-regulating and mind-calming acupuncture[at Lingtai(GV10), Shendao(GV11), bilateral Neiguan(PC6)and Baihui(GV20)]and the medication group, oral gavage of propafenone. Rabbit left ventricle was taken after the completion of the experiment. Cx43 expressions were compared and analyzed usingan immunohistochemical staining technique and a computer image processing system.ResultCx43 expression decreased significantly in the model group compared with the control group (P<0.01) and increased in the acupuncture and medication groups compared with the model group (P<0.05). There was no significant difference in Cx43 expression between the acupuncture and medication groups (P>0.05).Conclusion Adjusting Cx43 expression in myocardial cells may be one of the target points for this acupuncture treatment of arrhythmia.

Objective:To investigate the relationship between mandibular second molar calcification stage and cervical vertebrae maturity.Methods:Samples were derived from panoramic radiographs and lateral cephalograms of 500 subjects (223 males and 277 females)aged 9 to 18 years.Demirjian Index(DI)and cervical vertebrae maturation indicators(CVMI)were used for the evaluation of dental and skeletal maturity.Results:A significantly association was found between DI and CVMI(P <0.001).DI stage E was associated with CVMI Ⅱ(pre-peak of pubertal growth spurt).DI stages F and G was associated with CVMI Ⅲ and Ⅳ(peak of pu-bertal growth spurt).DI stage H was associated with CVMI Ⅴ and Ⅵ(end of pubertal growth spurt).Conclusion:DI and CVMI are significantly associated.Mandibular second molar DI stage is a reliable indicator of skeletal maturity.

BACKGROUND:The diagnosis of osteoporosis depends upon the bone mineral density T-score of ≤ -2.5 standard deviation or brittle fractures. Bone mineral density measurement combined with vertebral fracture assessment might prevent the missed diagnosis of osteoporosis due to bone mineral density evaluation alone, and improve the diagnosis rate of osteoporosis.
OBJECTIVE:To evaluate the effect of bone mineral density measurements combined with vertebral fracture assessment for the diagnosis of osteoporosis.
METHODS:Bone mineral density measurements of proximal femur and vertebral fracture assessment for lateral thoraco-lumbar images were consecutively done for 217 postmenopausal women who aged ≥ 50 years. The rate of osteoporosis diagnosed with bone mineral density T score was compared with that diagnosed with bone mineral density combined with vertebral fracture assessment. The effects of bone mineral density on the vertebral fracture were analyzed.
RESULTS AND CONCLUSION:92 (42.4%) patients had bone mineral density T score ≤ -2.5, which met the threshold for diagnosis of osteoporosis. 102 (47.0%) patients had osteopanic (-1>T>-2.5) and 23 (10.6%) had normal range of bone mineral density. 158 patients had no vertebral fractures and 59 (27.2%) patients had 101 vertebral fractures. The vertebral fracture rate was 21.6%in the patients with bone mineral density T> -2.5 and 34.8%in the patients with bone mineral density T ≤ -2.5, with significant differences (P<0.05). Bone mineral density in combination with vertebral fracture assessment for the diagnosis rate of osteoporosis was up to 54.8%, which was significantly higher than the rate diagnosed with only bone mineral density (12.4%;P=0.01). Bone mineral density measurement combined with vertebral fracture assessment improves the diagnosis of osteoporosis for postmenopausal women.
