AIM To observe the effect of deprot einised calf blood extract(DCBE) on experimental gastric ulcer in rats. METHODS Ulcer model of SD rats induced by acetic acid, half male and female, were divided into three group s randomly, the control group and the two treatment group DCBE (30 mg?kg -1 or 60 mg?kg -1 ). Following the two and four weeks of experiment, the gastric acid degr ee, activity of pepsin, area of ulcer, the number of tela leukocyte and activity of myeloperoxidase (MPO) were observed. RESULTS Gastric acid deg ree and activity of pepsin showed no significant difference between treatment gr oup and control group, either in DCBE 30 mg?kg -1 or in 60 mg?kg -1 , but area of ulcer, the number of tela leukocyte and the activity of myeloperoxi dase (MPO) showed a significant difference between treatment group and control group and the e ffects of 60 mg?kg -1 group were significantly decreased as compared with that of 30 mg?kg -1 group. CONCLUSION DCBE can significantl y promote tissue healing of gastric ulcer induced by acetic acid in SD rats.

Turkey is a presidential republic country located in the Eurasian continent, which has a universal health coverage since the health reform in 2003. The leading causes of death in this country are ischemic heart disease, stroke, and lung cancer. Besides, lower respiratory infections, chronic kidney disease, and hypertensive heart disease are the diseases which have a fastest growing rate. Chinese acupuncture was officially recognized by Turkey in 1991 with the promulgation of Acupuncture Treatment Legislation. At present, only trained practitioners and dentist could conduct acupuncture treatment, which was stated in Regulation of Tradition and Complementary Medicine Practice. The application of Turkish acupuncture and moxibustion is still applied in a simplified way that lack of TCM theory. Moreover, Chinese herbal medicine is still not officially recognized and still under control of the Ministry of Agriculture. Therefore, it is suggested to introduce TCM theory in the spread of acupuncture, to promote acupuncture research and clinical practice, to clarify the different standards between the two countries, and to cooperate in Chinese medicine researches, especially those related to the local high incidence and refractory disease so as to promote the development of TCM in Turkey and provide medical services for local residents.

American medical insurance is mainly composed of public medical insurance borne by the government and private medical insurance. The main cause of death in this country are ischemic heart disease, Alzheimer’s disease, and lung cancer. The motality rate mainly caused by drug use disorders, chronic kidney disease and Alzheimer’s disease. The development of Chinese herbal medicine is relatively slow and difficult. The education system has covered Traditional Chinese Medicine (TCM). However, there still exist certain challenges of the development of TCM acupuncture faces the challenge of localization; Chinese herbal medicine still lacks standardization and TCM education needs to be standardized. Based on the current situation, it is suggested to focus on the development of acupuncture and moxibustion, to promote the registration and declaration of Chinese herbal medicine products for treating difficult diseases, and to strengthen the international exchange of TCM education, so as to promote the development and spread of TCM in the United States.

Thailand is a constitutional monarchy located in the central and southern part in Southeast Asia. It mainly implements the civil service insurance plan, the social insurance plan and the "Thai 30" plan, and the government bears the main health expenditures. The Thai traditional and alternative medicine system includes Thai traditional medicine, indigenous medicine and alternative medicine. Traditional Chinese Medicine (TCM) belongs to the category of alternative medicine. Currently, Thai traditional medicine and Chinese acupuncture have been included in medical insurance. With Thailand’s approval of doctors to use Chinese medicine to treat diseases published (Notification No.1 of BE 2543), a series of activities such as the establishment of national TCM center, the certification of TCM doctors, and the set of TCM courses and training have promoted TCM development in Thailand. However, the application of Chinese herbal medicine is restricted by Thai medicine laws; the practical skills of acupuncture and moxibustion is insufficient; and the TCM education is not systematic and complete. Therefore, it is recommended to carry out extensive and continuous publicity in the future to promote policy and legislative support; to strengthen research and development of Chinese patent medicine on popular diseases in Thailand and promote localization; to establish a special practice training center to improve acupuncture clinical operation capacity; to add and refine the content of TCM regarding university education system as well as short-term training; and to encourage cooperation between China and Thailand in talent exchanges and scientific researches, promoting the development of TCM in Thailand.

Objective To investigate the causes of re-fractures of non fracture vertebral body after percutaneous kyphoplasty (PKP).Methods 512 patients (618 vertebral bodies) treated with PKP because of osteoporosis VCFs were recruited from June 2010 to June 2014.There were 107 males (121 vertebral bodies) and 405 females (497 vertebral bodies) with the mean age of 70.38±7.59 years old (51 to 91 years).There were 406 single segment fracture and 106 double segment fractures cases,and the fracture segments were T4 to L5.The T value of the patients' bone mineral density (BMD) was from-1.0 to-5.2 SD.The clinic characteristics of all the patients including age,sex,body weight,body height,body mass index (BMI),BMD score of the spine,volume of bone cement,restoration rate of anterior/middle vertebral height,postoperative complications (pulmonary embolism,bone cement leakage,nerve injury),and treated vertebral level were analyzed.Results 52 patients (10.16％,52/512) experienced refractures of non fracture vertebral body after kyphoplasty,and 4 experienced re-fracture of the fracture vertebral body after kyphoplasty.The average age of the 52 patients was 71.88±7.74 years old,meanwhile,the ratio of female was 94.23％ (49/52),the mean T value of BMD-4.03±0.60 SD,the ratio of initial double segment fractures 51.92％ (27/52).In addition,among the 456 cases with no fracture,the average age was 70.21±7.56 years,the ratio of female was 77.19％ (352/456);the mean T value of BMD was-2.89±0.55 SD;the ratio of initial double segment fractures was 17.32％(79/456).The data above (age,T value of BMD and initial double segment fractures) were all with statistical significant differences.Whereas the BMI,volume of bone cement,intervertebral disc leakage and restoration rate of anterior/middle vertebral height had no significant difference between the two groups.Furthermore,in the re-fracture of non fracture vertebral body group,32 cases (61.54％,32/52) were nonadjacent fractures,and 20 (38.46％,20/52) were adjacent fractures.Conclusion Osteoporosis degree,female and initial double segment fractures were major risk factors in the development of re-fracture of non fracture vertebral body after PKP.

Objective To understand the clinical features of patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) complicated by cytomegalovirus (CMV)viremia.Methods The clinical data of 249 cases of HIV/AIDS patients hospitalized in Beijing Ditan Hospital from Oct 2008 to Nov 2009 were analyzed retrospectively,in which 43 HIV/AIDS patients were diagnosed with CMV viremia.The symptoms and signs,cerebrospinal fluid (CSF)tests,and pathological detections by bronchoscope,gastroscope and fibercoloscope were collected.The database was set up using Excel software.The association between cellular immunity and CMV DNA level was determined by SPSS12.0 software.Results Forty-three patients (17.3%)were diagnosed with CMV viremia by positive results of CMV pp65 antigen and CMV DNA tests; 14 patients manifested retinal bleeding or infiltration and 4 patients displayed retinal fibrosis; 1 patient was diagnosed with CMV pneumonitis by pathological results of bronchoalveolar lavage fluid.Low level of CD4+ T lymphocytes and CMV DNA levels were positively correlated.Conclusions CMV pp65 antigen and CMV DNA should be detected in HIV/AIDS patients with CD4+ T lymphocytes less than 100 × 106/L and anti-CMV treatment should be given according to the results.Ophthalmologic examination and bronchoalveolar lavage fluid pathological detection are effective methods in diagnose of CMV retinitis and pneumonitis.

South Africa is an ethnically and culturally diverse presidential republic country. The medical and health system consists of public and private medical care. AIDS, lower respiratory infections, neonatal diseases, and interpersonal violence and road injuries are the leading causes of adult death. South Africa has rich herbal resources, and a long history of traditional medicine, which is mainly black African traditional medicine. Until the establishment of diplomatic relations between China and South Africa in 1998, the development of TCM was significantly improved, and legislation of TCM was adopted by the government in 2000. Chinese herbal medicine has not yet formed industrial standardization, the TCM application and TCM education are insufficient. Therefore, it is suggested to accelerate the standardization of TCM, to strengthen the TCM education for professional TCM practitioners, and to form a large-scale, industrial and standardized development model. Only in these ways can TCM provide good medical services for residents in South African.

The Philippines’ medical system is mainly based on the provincial responsibility system and the limited hierarchical. The Philippine government implement Philhealth program which can provide medical insurance for most people. The top 10 fatal diseases in this country includes ischemic heart disease, stroke, lower respiratory tract infection and so on. Of these diseases, the increasing rate of hypertensive heart disease, chronic kidney disease and diabetes are fast. Bone setting, massage and herbal medicine are the major form of traditional medicine in the Philippines. The acceptance of acupuncture and moxibustion by the government and local people is relatively high acupuncture and moxibustion therapy has been included in its medical insurance. There are many limitations on the development of Traditional Chinese Medicine (TCM) theory and Chinese herbal medicine in the Philippines, and the clinical application of acupuncture and Chinese herbal medicine is still limited. TCM education in the Philippines is still not systematic. Therefore, it is suggested to improve the education system of TCM, strengthen the promotion of acupuncture and moxibustion, give full play of the advantages of TCM for native high-risk diseases, and to make use of modern technologies such as telemedicine.

Internal contamination of radionuclides in the event of nuclear emergencies can lead to serious harm to human health. The research and development of radionuclide chelating agents and the application of new technologies can reduce the internal damage caused by radionuclides. Compared with traditional preparations, the nano-preparations have the advantages of improving drug dissolution, targeting and positioning drug release, and easily passing through biofilm barrier. In recent years, many scholars have used different nano-preparation forms for different decorporation drugs, including nanoparticles, nano-liposomes, nano-emulsions, etc., to conduct related research in order to achieve better clinical application effects. Nanomaterials with excellent properties have the advantages of high efficiency, rapid adsorption and high biocompatibility, etc., and have been used more and more widely in radionuclide decorporation. In this paper, combined with the relevant literatures at home and abroad, the internal contamination of radionuclides is classified according to nuclide-deposited sites of tissues and organs, and the applications of related nanoformulations and nanomaterials in radionuclide decorporation are introduced in order to provide reference for further research.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA
