The CO I gene sequences of Qianghuoyu, Pachytriton labiatus and Gehyra mutilata were achieved by PCR amplification and bi-directional sequencing. Furthermore, a pair of specific primers SJYW1 and SJYW2 in the non-conservative district were designed through sequence alignment. The PCR reaction condition was established by changing the annealing temperature and cycle numbers. The results showed that 350 bp DNA fragment was amplified from Qianghuoyu in PCR with annealed temperature at 54 °C and the cycle number was 25 cycles, whereas not any DNA fragment was amplified from P. labiatus and G. mutilata under the same reaction condition. This method is well-performed in the identification of Qianghuoyu for its excellent specificity and repeatability.

We evaluated the patient in the early,advanced or healing phase of the disease by MRI in the treatment of chronic brucellosis spondylitis and to guide the clinical treatment.MRI images of 40 patients with clinically diagnosed chronic brucellosis spondylitis were analyzed retrospectively.The imaging findings of early,advanced and healing patients were summarized.MRI showed abnormal signals in the vertebral body,intervertebral disc,paraspinaI and psoas muscle.It is early stage if the intervertebral space was normal,and advanced stage if combined with interverbral space stenosis.It demonstrated short T1 and short T2 signal or similar to the normal vertebral body,combined with intervertebral space stenosis,for the healing stage.According to the specific imaging manifestations of chronic brucellar spondylitis in the course of disease development,it is possible to evaluate the clinical stage of the disease and guide the rational selection of clinical treatment.

Zuotai (gTso thal) is a typical representative of Tibetan medicines containing heavy metals, but there is still lack of modem safety evaluation data so far. In this study, acute toxicity test, sub-acute toxicity test, one-time administration mercury distribution experiment, long-term mercury accumulative toxicity experiment and preliminary study on clinical safety of Compound Dangzuo were conducted in the hope of obtain the medicinal safety data of Zuotai. In the acute toxicity test, half of KM mice given the lethal dose of Zuotai were not died or poisoned, and LD50 was not found. The maximum tolerated dose of Zuotai was 80 g x kg(-1). In the subacute toxicity test, Zuotai could reduce ALT, AST, Crea levels in serums under low dose (13.34 mg x kg(-1) x d(-1)) and medium dose (53.36 mg x kg(-1) x d(-1)), with significant difference under low dose, and increase the levels of ALT, AST, MDA, Crea in serums under high dose (2 000 mg x kg(-1) x d(-1)); besides, the levels of BUN and GSH in serums reduced with the increase in dose of Zuotai, indicating a significant dose-effect relationship. In the one-time administration distribution experiment, the content of mercury in rat kidney, liver and lung increased after the one-time administration with Zuotai, with a significant dose-dependent relationship in kidney. In the long-term mercury accumulative toxicity experiment, KM mice were administered with equivalent doses of Zuotai for 4.5 months and then stopped drug administration for 1.5 months. Since the 2.5th month, they showed significant mercury accumulation in kidney, which gradually reduced after drug withdrawal, without significant change in mercury content in liver, spleen and brain and ALT, AST, TBIL, BUN and Crea in serum. At the 4.5th month after drug administration, KM mice showed slight structural changes in kidney, liver and spleen tissues, and gradually recovered to normal after drug withdrawal. Besides, no significant difference in weight gain was found between the Zuotai group and the control group. According to the findings of the clinical safety study of Dangzuo, after subjects administered Dangzuo under clinical dose for one month, their serum biochemical indicators, blood routine indicators and urine routine indicators showed no significant adverse change. This study proved that traditional Tibetan medicine Zuotai was slightly toxic, with a better safety in clinical combined administration and no adverse effects on bodies under the clinical dose and clinical medication cycle. However, long-term high-dose administration of Zuotai may have a certain effect on kidney.

According to the law of circulation of meridians and the locations of acupoints, the opposite acupoints were proposed. It facilitates comprehension of the routes of meridians and the locations of acupoints. Application of opposite needling or penetrative needling, it is easy to practice and the effectiveness is significant. Promoting this concept into acupuncture training, can expand out from acupoint to meridian, from one meridian to other meridians, it will generate good rewards.

Fatal anaphylactic shock is common in forensic practice. However, it is difficult to diagnose for lacking specific pathological and morphologic changes in forensic autopsy. The application of some biochemical indicators is of great significance. This paper reviews the biological characteristics of some biochemical indicators and detection methods. The forensic application, problems and prospects of these indicators are also introduced in details. The stable biochemical indicators, IgE, tryptase and chymase, show great potential and advantages in the identification of fatal anaphylactic shock in forensic medicine.

Objective: To summarize the distributing rule of TCM syndrome elements of common diseases by analyzing the literature of Depression,Chronic Hepatitis B,Chronic Renal Failure,Chronic Obstructive Pulmonary Disease,Menopausal Syndrome.Methods: We selected eligible literatures,then established database with EpiData 3.0 software and computed the frequency of TCM syndrome elements with SPSS 12.0 software.Results: ①Liver,heart,spleen,lung and kidney are common TCM syndrome elements of location of disease.②Yin deficiency,yang deficiency,heat,qi stasis,qi deficiency,blood stasis,damp and phlegm are common TCM syndrome elements of nature of disease.③There are TCM syndrome types between 62 and 148,but the sum of frequency of leading syndrome types which includes disease information is mostly no more than 50%.There are TCM syndrome elements between 19 and 47,but the sum of frequency of leading syndrome elements which includes disease information is mostly above 80%.Conclusion: It is convenient to study TCM syndrome from the aspect of TCM syndrome elements,so we should thoroughly keep on studying TCM syndrome elements.

BACKGROUNDCoronary computed tomographic angiography (CCTA) has been widely used in patients who are at intermediate risk for having stable coronary artery disease (SCAD), and 2013 European Society of Cardiology Guidelines on the Management of SCAD (2013G) recommended the appropriate application of CCTA. However, 2013G has not been subjected to systematic analyses for subsequent impact on clinical practice.

METHODSA total of 5320 patients suspected with SCAD were enrolled and scheduled for CCTA from March 2013 to September 2014. For each patient, pretest probability of SCAD was calculated according to updated Diamond-Forrester model (UDFM). Appropriate CCTA or appropriate stress test was determined as described in the 2013G. A generalized estimating equation model was used to determine the trends in the half-monthly rate of appropriate CCTA.

RESULTSOverall, only 61.37% of patients received appropriate CCTA, and there was insignificant change over time (P = 0.8701). The application of CCTA in patients who should have had a stress test accounted for most of the inappropriate CCTA before (22.29%) or after (19.98%) the publication of the 2013G. In all patients or any subgroup, no significant change in the adjusted half-monthly rate of appropriate CCTA was found after the publication of the 2013G (odds ratio, 1.002; 95% confidence interval, 0.982-1.021; P = 0.8678).

CONCLUSIONSThese findings suggest that the 2013G have not, to date, been fully incorporated into clinical practice, and the clinical utilization of CCTA remains unreasonable to some extent.

OBJECTIVETo investigate the clinical effect of Devine's technique with free skin grafting in the treatment of concealed penis with prepuce deficit.

METHODSThis study included 7 children with concealed penis, aged 6 - 15 (mean 8.6) years, 6 of them treated by circumcision previously. All the patients underwent Devine's operation to resect the inelasticity sarcolemma and lengthen the penis. The length of prepuce deficit ranged from 2 to 4 cm. Intermediate split thickness skin grafts of the corresponding length were taken from the femoribus internus to wrap up the tunica albuginea penis, followed by the procedures of saturation, encapsulation and fixation.

RESULTSSurgery time ranged from 70 to 120 minutes, averaging 90.5 minutes. The penis was prolonged about 2 - 4 cm after surgery. A 6-month follow-up revealed desirable penile appearance and normal penile erection.

CONCLUSIONDevine's technique with free skin grafting from the femoribus internus is an ideal treatment for concealed penis with prepuce deficit.
