Chinese medicine and Tibetan medicine both belong to the traditional medicine, and have their unique background and theoretical systems. There are similar features and differences in diagnosis of disease, syndrome and treatment between Chinese medicine and Tibetan medicine. Tibetan Zhenbu disease is common and frequently-occurring in plateau area with high morbidity, which is corresponding to rheumatoid arthritis in modern medicine and the category of Bi syndrome in Chinese medicine. During a long period of clinical efficacy verification, Tibetan treatment of Zhenbu disease presents to be little side effects, good curative effect, safe and economic etc. In the review, according to the introduction of Tibetan medicine and Chinese medicine, Zhenbu disease of Tibetan medicine and Chinese Bi syndrome will be compared in their pathogeneses and treatments to understand advantages and peculiarities of Tibetan medicine. The development of Tibentan medicine in the future will also be pointed out.

AIM: To explore the relationship of central retinal vein occlusion ( CRVO) and atherosclerosis ( AS) .
METHODS:Fifty cases of CRVO patients were chosen as the observation group in our hospital from October 2012 to October 2014, other 50 patients with AS ( non-CRVO) as control group. In the control group, 22 cases of AS mild stenosis, moderate stenosis in 24 cases, 4 cases of severe stenosis ( 3 cases implanted stent ) . According to the severity, two grade prevention primary prevention therapy, and cerebral vascular disease treating stroke, corresponding drug treatment was undergone. Two groups of patients were performed cervical carotid artery color Doppler ultrasound examination, including assessing plaque, carotid artery intima-media thickness ( IMT) , the degree of stenosis of internal carotid artery blood flow velocity and the systolic peak ( PSV ) , end diastolic blood flow velocity ( EDV) , resistance index ( RI) values for kinetic parameters etc. All the indexes of the two groups were compared with color Doppler ultrasound examination results, to evaluate the correlation between CRVO and AS.
RESULTS: In the observation group, 15 cases were detected of carotid artery with mild stenosis, 28 cases of arterial diameter reduced <50%, carotid artery moderate stenosis, arterial diameter was reduced from 50% ~69%, 6 cases of carotid artery stenosis, arterial diameter was reduced from 70% ~99%, 1 patient with ipsilateral carotid artery near occlusion. In the control group, 22 cases were of AS mild stenosis, moderate stenosis in 24 cases, 4 cases of severe stenosis ( 3 cases implanted stent ) . The eyes with CRVO increased IMT, PSV and EDV decreased, RI value increased (P<0. 05). Compared with the control group, hypertension, hyperlipidemia, hypercholesterolemia, diabetes mellitus in observation group were statistically significant difference (P<0. 05). The control group of 2a of follow-up showed no recurrence during CRVO.
CONCLUSION: CRVO and AS are highly correlated, the neck of Doppler ultrasound examination can clearly reflect the central retinal vein blood supply, the standard treatment for AS disease, can reduce the risk of CRVO, with certain clinical significance.

High altitude polycythemia (HAPC) had become one of the main common chronic diseases, which had seriously threatened the health of Plateau people. In the Tibetan medicine classic bookSi-Bu Yi-Dian, there were recordings on HAPC treatment methods and medications, which had the unique advantages of identified therapeutic effect with little side effect. This article analyzed Tibetan medicine in the prevention and treatment of HAPC from aspects such as etiology and pathogenesis, clinical treatment advantages and modern innovation study. Questions were also raised on lacking of standardization on HAPC clinical effectiveness, as well as Tibetan medicine compound material basis and action mechanisms were unclear. It was proposed that based on the inheritance of Tibetan medicine theoretical basis and clinical therapeutic effect, the Tibetan medicine original thinking should be combined with modern science and technology, in order to strengthen the analysis of ancient literature collection in HAPC treatment and data mining in medication experiences. The clinical treatment standards and medication plan should be standardized. Methods of systems biology, such as metabolomics, can be used in the further study of the scientific connotation of HAPC treatment by Tibetan medicine.

Objective To study whether 3D computerized pre?operative planning is accuracy and reliability in CroweⅣtype developmental dysplasia of the hip (DDH) patients undergoing total hip arthroplasty (THA). Methods Between September 2009 and February 2011, 20 CroweⅣtype DDH patients (20 hips) were included in this study. The 3D pre?operative planning was performed using Mimics software to predict the acetabular component size, acetabular component abduction angle, hip rota?tion center position, the acetabular component coverage and number of patients received structural bone graft. The results were compared with traditional acetate templating technique and post?operative results. Results 70%(14/20) components were pre?dicted exactly and 30%(6/20) components were predicted with one size using 3D computerized planning, comparing with 25%(5/20) components were exactly, 45%(9/20) components were with one size and 30%(6/20) were with two size or more using conven?tional acetate templating technique. Statistically analysis revealed that 3D planning was more accuracy than templating technique regarding acetabular component prediction (t=-4.66, P=0.00). There was no significant difference between the 3D computerized planned acetabular component abduction angle (3D plan 41.10°±4.87°, postoperative 44.98°±10.83°, t=0.88, P=0.42), hip rota?tion center distance (horizontal distance:3D plan 77.51 ± 7.78 mm, postoperative 79.85 ± 8.61 mm, t=-1.95, P=0.11;vertical dis?tance:3D plan 42.79±8.22 mm, postoperative 44.98±10.83 mm, t=-1.27, P=0.26), acetabular component host coverage (3D plan 77.73%± 10.51%, postoperative 78.98%± 10.24%, t=-1.84, P=0.09), and that found post?operatively. Five patients were consid?ered to need structural bone graft according to 3D computerized planning, which was highly coincident with the intraoperative find?ings in all five cases. Conclusion 3D computerized pre?operative planning using Mimics software is an accurate and reliable technique in treating CroweⅣtype DDH patients undergoing THA.

This study was aimed to reveal the species characteristics of Chinese patent medicines for antitussive ef-fect and provide references for developing new drugs. This research targeted Chinese patent medicines for antitussive effect which were included in the Pharmacopoeia of the People's Republic of China and the New National Chinese Patent Medicines as well as those characterized by keywords such as cough cure, cough alleviating, antitussive effect, cough, persistent cough. The analysis was made on the species characteristics, such as the number of Chinese patent medicines for antitussive effect, license number, ethnomedicine patent medicines, drugs for children use, protection of varieties of traditional Chinese medicine, the number of drugs, the generic names of drug, and drug forms. The results showed that 684 Chinese patent medicines for antitussive effect collected in this research had ac-counted for 8.60% of the total 7 260 of Chinese patent medicines. A total of 7 450 license numbers were approved, and 33% of the Chinese patent medicines shares one license number. One Chinese patent medicine owns 16.6 li-cense numbers on average. Ethnomedicine patent medicines had 3 Tibetan prescriptions such as the Shiwuwei Chenxiang pill and 4 Mongolian prescriptions, such as the Siwei Tumuxiang powder. Drugs for children accounted for 14%, including 9 forms. The type of the generic names of drug reached 16 and most of them originate from abbrevia-tions of the main drug in prescription. The number of drugs in prescription ranges from 8 to 16. Chinese patent medicines for antitussive effect involved 16 forms, of which the proportion of the use of solid preparation was higher than the liquid preparation. It was concluded that Chinese patent medicines for antitussive effect were characterized by such advantages such as a variety of species, various forms, the reasonable number of drugs, considerable medicine retail market share and drug for children use which can meet the clinical needs, and meanwhile some prob-lems, such as a lack of criteria for the generic names of drug, the homogenization of fierce competition, and inade-quacy of ethnomedicine patent medicines.

OBJECTIVETo evaluate the efficacy of three categorized formulas for tonifying Shen yang, i.e. Shenqi Pill (SP), Yougui Pill (YP), and Yougui Drink (YD) based on rough set, thus exploring the law of compatibility between the core herbs and the edge herbs as well as the law of compatibility between the yang-tonifying herbs and the yin-tonifying herbs in the core herbs.

METHODSThe rats were divided into the normal group, the Shen-yang deficiency model group, and the original prescription group, the core herbs group, and the edge herbs group of this three categorized formulas for tonifying Shen yang, 11 groups altogether. Thyroxine (T4), cortisol (CORT), and testosterone (T) were detected respectively. The decision rules model based on rough set was set up, the interactions between various herbs were analyzed according to the decision rules.

RESULTSThere were synergies between yam and cinnamon, yam and aconite, as well as yam and wolfberry. Poria alisma, Cortex Moutan, and oriental waterplantain tuber had no effect themselves, but they had synergistic effects with the core herbs in SP. Angelica had a certain effect itself, but its functions were different to different core herbs in YP. Licorice had no effect itself, and it was antagonistic with the core herbs in YD.

CONCLUSIONSThe compatibility of core herbs of categorized formula for tonifying Shen yang should focus on benefiting both yin and yang, as well as mutual rooting of yin-yang. Appropriate edge herbs should be chosen for compatibility according to different core herbs. The decision rules model based on rough set has a good prospect in exploring the law of compatibility of the categorized formulas.
