Trans-cinnamaldehyde, the main component of volatile oil from cassia twig or Cinnamomum cassia, which is a traditional Chinese herbal medicine. Trans-cinnamaldehyde is a kind olefine aldehyde of organic compounds and has many pharmacological properties, such as anti-inflammatory, anti-tumor, anti-bacterial, antidiabetic, anti-obesity, and neuroprotection etc. The compound has preventive and therapeutic effects on the nervous system, cardiovascular, cancer, diabetes and other diseases. Trans-cinnamaldehyde, as a preventive care of nature medicine, has great clinical and market potential. This paper gives a review about the pharmacological effects and mechanism of trans-cinnamaldehyde researched in the latest five years. We hope to provide some basic information for further research on trans-cinnamaldehyde.

Objective To analyze the clinical and immunological manifestations of antiphospholipid syndrome(APS)in a cohort of 100 patients.Methods The clinical and serologic features of APS(Sapporo preliminary criteria)in 100 patients were analyzed retrospectively.Results The cohort consisted of 79 female patients and 21 male patients witb a mean age of 36?13 years at diagnosis.Primary APS was presented in 37% of patients;APS was secondary to systemic lupus erythematosus(SLE)in 46%,lupus-like syndrome in 14%. Eighty percent of the patients had thrombosis,43(54%)patients had venous thrombosis,18(22%)had arterial thrombosis,15(19%)had both arterial and venous thrombosis.4(5%)had thrombosis of microcirculation. Forty-two(52%)patients presented thrombosis at a single site,26(32%)at two sites,12(15%)at three or more sites.Forty-five(56%)patients experienced one thrombotic episode,20(25%)patients had only one re- currence,and 15(19%)had more thrombosis.The most common manifestations of thrombosis were deep vein thrombosis(36%),pulmonary embolism(30%)and stroke(26%),with heart,kidney,gastrointestinal tract and other organs involvements.Thirty-four(51%)female patients had spontaneous fetal losses including intrauter- ine fetus death and recurrent spontaneous abortion.Seventy-one(71%)patients developed thromboeytopenia. The presence of antieardiolipin antibody(ACL)was detected in 84 patients(84%).Among 90 patients with APS,alone ACL was detected in 38 patients(42%),both ACL and lupus anticoagulant(LA)were detected in 36(40%),LA alone in 16(18%).Patients with APS associated with SLE or lupus-like syndrome had higher frequency of arthritis,leukopenia,antinuclear antibodies(ANA)and low complement levels.Female patients had a higher frequency of leukopenia,ANA and ACL.Male patients had a higher prevalence of deep venous thrombosis in the lower limbs and LA.Conclusion APS is an autoimmune disorder characterized by recurrent arterial and venous thrombosis,fetal loss,or thrombocytopenia with the presence of ACL and/or LA.In APS secondary to with SLE,the patient's sex can modify the disease expression and define specific subsets of APS.

Objective: To observe the clinical efficacy of acupoint pressure plus long-snake moxibustion for upper-limb spastic hemiplegia after cerebral infarction. Methods: A total of 100 patients were randomized into a control group and an observation group, with 50 cases in each group. Both groups were treated with the same conventional internal medicine and rehabilitation training. The control group was treated with additional acupoint pressure therapy, and the observation group was treated with long-snake moxibustion on the basis of the treatment given to the control group. The Ashworth grade, Fugl-Meyer assessment upper limb scale (FMA-UL) and Barthel index (BI) were evaluated, and the root mean square (RMS) values of biceps brachii and flexor carpi radialis on the affected side were measured before and after treatment. The efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the Ashworth grade of the observation group was superior to that of the control group (P<0.05). The scores of FMA-UL and BI in both groups increased compared with those before treatment (all P<0.05), and the scores of FMA-UL and BI in the observation group were higher than those in the control group (both P<0.05). The RMS values of biceps brachii and flexor carpi radialis in both groups decreased compared with those before treatment (all P<0.05), and the RMS values of biceps brachii and flexor carpi radialis in the observation group were lower than those in the control group (both P<0.05). Conclusion: Based on conventional internal medicine and rehabilitation training, acupoint pressure plus long-snake moxibustion has great therapeutic efficacy for upper-limb spastic hemiplegia after cerebral infarction. It can improve the degree of spasticity of the affected upper limb, reduce the muscle tone of biceps brachii and flexor carpi radialis on the affected side, and enhance the mobility of the affected limb and the activities of daily living.

This paper describes a calibration phantom system for QCT bone mineral density determination, which consists of 4-standard-solid-sample calibration phantom, a quality assurance (QA) phantom and the bone mineral density analysis software. The system adds to the new applications of CT systems, and provides a new method with a good accuracy and reliability for the examination, diagnosis, prevention, treatment of osteoporosis diseases and the observation of curative effect of drugs.

0.05). The relative bioavailability of tested capsules to reference tablets was (99.3?13.1)% Conclusion Both formulations are of bioequivalence.

To study the clinical skills training methods and formulate a training objective for pediatric long-year-program students, to let the students, through three years of training program, reach the clinical ability as a chief resident, with better laboratory research skills, teaching awareness and responsibility, and also with good comprehensive quality and excellent English, and finally become clinical talents with great potential and innovation, this report summarized our study results of training two terms of long-year-program pediatric graduates, who fully meeted the training objectives in the department's practice.

This study adopted a large sample, multicenter, registered hospital centralized monitoring nested prospective case-control study design. From the real world clinical application of Shenqi Fuzheng injection, monitored 30 026 cases of patients with the use of Shenqi Fuzheng injection. A total of 51 adverse drug reaction (ADR) cases was monitored, including 1 case of severe adverse reactions. ADR incidence rate was 1.7 per 1,000. Blood samples were collected from patients with allergic reactions and their matched controls. Related biological indicators of allergic reactions were unified detected and analysed in order to explore the mechanism of allergic reaction and promote the clinical safety.

Objective To investigate the correlation between vitamin A and surfactant protein (SP)-B, SP-C in human body,and to explore the effects on lung development and pulmonary function of neonates. Methods We collected the blood samples of 170 pregnant women and umbilical cord serum of their neonatal babies. The levels of vitamin A in pregnant women and their neonatal babies,and the levels of SP-B and SP-C in neonatal umbilical cord serum were detected by ELISA. We conducted a follow-up by standard telephone questionnaire,which we concerned was the number of respiratory tract infection within six months,in order to assess the neonatal pulmonary functions. Results (1) There was a positive correlation between the vitamin A levels in neonatal umbilical cord blood and in the blood of pregnant women(r=0. 866,P<0. 05). (2) There was a positive correlation between the vitamin A levels in neonatal umbilical cord blood and the levels of SP-B,SP-C in the blood(r=0. 817,P<0. 05). (3)In the follow-up of 170 cases of infants within six months,three cases with pneumonia hospitalized more than once,but no respiratory distress syndrome hap-pened. Conclusion Vitamin A can be used as an important biological marker to evaluate the neonatal pul-monary maturity. If we detect the vitamin A levels of pregnant women,increase the intake of vitamin A,we can improve the content of SP-B,SP-C,improve the development of neonatal lung function in growth.
