Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo(BPPV).Methods The clinical data of 521 patients with BPPV were collected.The percentage of patients with BPPV in all the outpatients with dizziness and vertigo,the clinical characteristics of BPPV,and the prevalence of comorbidity with migraine were analyzed.Results BPPV accounted for 35.7% of patients with vertigo and 12.1% of patients with dizziness.Among the 521 patients with BPPV,158(30.3%)were male and 363(69.7%)were female,with an average age of(57.5?12.8)years old(20 to 93 years old).Right semicircular canals were involved in 323 cases(62.0%),and left semicircular canals in 187 cases(35.9%).The latency period of nystagmus of vertical canals was(3.22?2.37)s,and time of persistence was(8.31?7.98)s.The latency period of nystagmus of horizontal canals was(2.33?1.50)s,and the time of persistence was(14.77?11.40)s.There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals(P=0.001 and P=0.000).Fifteen patients(2.9%)had a history of head trauma and 39(7.5%)were complicated with migraine.Conclusion BPPV is prevalent in patients with dizziness and vertigo,and misdiagnosis and missed diagnosis should be avoided.

Realgar-containing Niuhuang Jiedu tablet (NHJD) has been applied in clinic for more than 800 years. However, because realgar contains arsenic (As), it has aroused wide concerns and controversies both at home and abroad. Currently, there are two misunderstandings about realgar-containing Chinese patent medicines. First, some people exaggerated realgar's toxicity as that of arsenic. Second, they recommended to remove realgar from traditional Chinese medicine compounds. In this paper, the authors summarized the advance in studies on NHJD, and proposed different opinions: (1) It is inappropriate to take total As as the index in safety evaluation of NHJD. (2) The toxicity of NHJD is dependent on the dose and duration of administration. (3) Realgar is an active ingredient of NHJD, and shall be deeply studied. Classic realgar-containing traditional Chinese medicine prescriptions, such as Niuhuang Jiedu tablet, shall be evaluated with rigorous modern scientific basis, with the aim to guide rational and safe application.

OBJECTIVETo observe clinical therapeutic effect of herbs-partitioned moxibustion at Shenque (CV 8) on Parkinson disease.

METHODSNinety cases of Parkinson disease were randomly divided into a treatment group (n=4) and a control group (n=36) in order of visiting. The two groups were treated with routine western medicine for treatment of Parkinson disease, and herbs-partitioned moxibustion at Shenque (CV 8) was added to the treatment group. Their comprehensive therapeutic effects were observed and modified UPDRS cumulative scores were compared.

RESULTSThe total effective rate was 83.3% in the treatment group, significantly better than 58.3% in the control group (P < 0.01); the modified UPDRS cumulative score was reduced by 74.1% in the treatment group, significantly better than 16.7% in the control group (P < 0.01).

CONCLUSIONHerbs-partitioned moxibustion at Shenque (CV 8) has a certain therapeutic effect on Parkinson disease.

0.05).Conclusions These results suggest that the polymorphisms of triplet repeat GGC or combination of CAG and GGC of the androgen receptor is signifi- cantly associated with Han men with androgenetic alopecia in the Eastern China. However, genetic polymor- phism of 5?-reductase may not directly associated with androgenetic alopecia in our study population.

Robust and efficient control of therapeutic gene expression is needed for timing and dosing of gene therapy drugs in clinical applications. Ribozyme riboswitch provides a promising building block for ligand-controlled gene-regulatory system, based on its property that exhibits tunable gene regulation, design modularity, and target specificity. Ribozyme riboswitch can be used in various gene delivery vectors. In recent years, there have been breakthroughs in extending ribozyme riboswitch's application from gene-expression control to cellular function and fate control. High throughput screening platforms were established, that allow not only rapid optimization of ribozyme riboswitch in a microbial host, but also straightforward transfer of selected devices exhibiting desired activities to mammalian cell lines in a predictable manner. Mathematical models were employed successfully to explore the performance of ribozyme riboswitch quantitively and its rational design predictably. However, to progress toward gene therapy relevant applications, both precision rational design of regulatory circuits and the biocompatibility of regulatory ligand are still of crucial importance.

Some champers besides Miraculous Pivot: Channels and Vessels in Huangdi's Internal Classic are involved in diseases of channels and vessels, and most of them which mainly discuss diseases of channels and vessels are explained in the type of six channels of feet. Studies have showed that the diseases of six channels of the feet are closely related with diseases of channels and vessels in the medical books of bamboo slips and silk cloth, indicating that on the one hand, the studies on diseases of channels and vessels are not only limited in Miraculous Pivot: Channels and Vessels, and on the other hand, the influence of the literature of channels and vessels in the medical books of bamboo slips and silk cloth is quite profound and lasting. Widening the field of vision of investigating concept of diseases of channels and vessels, and looking closely at the course of history from academic development are favorable to deeply understanding diseases of channels and vessels, even early theories of channels and vessels.

Objective: To study change of serum high sensitive cardiac troponin T (hscTnT) concentration in coronary circulation of patients with non ST-elevation acute coronary syndrome (NSTE-ACS). Methods: The subjects were all selected from our hospital, including 46 NSTE-ACS patients （NSTE-ACS group）, 42 patients with stable angina pectoris (SAP group) and 30 cases with negative coronary angiography results（healthy control group）The hscTnT concentrations in coronary venous sinus, coronary artery (CA) and peripheral serum were measured in three groups respectively. The results were compared and analyzed. Results: Compared with healthy control group, the hscTnT concentrations in coronary venous sinus, CA and peripheral venous serum all significantly increased in NSTE-ACS group and SAP group, P<0.01 all. Compared with hscTnT levels in CA and peripheral venous serum, there was significant increase in coronary venous sinus [(0.9657±0.5863) μg/L vs. (0.9562±0.7853) μg/L vs. (1.3018±1.1024) μg/L, P<0.05] in NSTE-ACS group. Conclusion: The serum hscTnT concentrations in peripheral vein, coronary artery and coronary venous sinus all significantly increase in NSTE-ACS patients, especially in coronary venous sinus.
