BACKGROUND:Traditional Chinese medicine glossoscopy observes tongue image by vision,and to diagnose diseases by physicians'clinical experiences,which lacks of objective diagnostic methods and criteria;finally resulting in affecting the effectiveness of this diagnostic method.Therefore,it is necessary to realize quantitive and objective glossoscopy using techniques such as computer vision.Tongue body segmentation is the premise of the tongue image recognition diagnostic system.The quality of segmentation directly affects the sequent work.At present,there are many methods of tongue body segmentation,but obtained results cannot ensure the accuracy,and the anti-interference ability is poor.OBJECTIVE:To design a new method of tongue image segmentation,and effectively isolate tongue body.METHODS:According to tongue-images gray and color's features,a segmentation method of combining gray projection and threshold-adaptive way is presented in this paper.By this method,the intensity image of a colorful tongue-image is firstly projected at horizontal and vertical direction to locate the tongue-body area,and then threshold-adaptive way Otsu is used to segment the located area.RESULTS AND CONCLUSION:Tongue-body segmentation is the basis of automatic tongue-images analysis.The following 281 tongue-images segmentation experiments show the efficiency of this method.

In the book of Chinese Acupuncture and Moxibustion by CHENG Dan-an, direct moxibustion with moxa cone was regarded as a classic style of moxibustion because of its innate character of heat induced thermal stimulus and burn toxin. CHENG Dan-an made the quantity of moxibustion more controllable through the selection of moxa wool, the size and number of moxa cones, and the tightness of moxa cones, etc. CHENG Dan-an 's clinical experience is summarized through treating stubborn and infectious diseases with direct moxibustion with moxa cone. The results showed that only with understanding the characteristics of moxibustion and key pathological mechanism of suitable disease could direct moxibustion with moxa cone and the appropriate methods be performed correctly. CHENG Dan-an confirmed the clinical effect of treating stubborn and intectious diseases with direct contact moxibustion with moxa cone, and optimized the specific operation scheme of direct moxibustion with moxa cone. It tell us that we should deeply study on moxibustion, to make it wide spread in the hereafter, bring benefit to mankind.

Herpesviruses is one of the most common human infectious diseases, which can be divided into different types based on clinical infection degree.Herpes simplex virus usually results in buccal and genital mucocutaneous infections, while cytomegalovirus is the most common opportunistic pathogen associated with significant morbidity and mortality in immunocompromised hosts, especially in transplant and cancer patients.Although nucleoside analogues are effective antiviral drugs, the emergence of drug-resistant viruses has created a barrier for the treatment of herpesviruses infections, especially in immunocompromised patients.Therefore, novel therapeutic agents are needed to avoid the limitations of drug resistance.In this article, research progress in the therapeutic agents for drug-resistant herpesviruses was reviewed from the aspects of non-nucleoside analogues, novel antiviral targets and newly antiviral mechanisms.

Objective To understand oral submucous fibrous (OSF) because the hair cause of disease and the quantitative corresponding measures,do a good job in OSF prevention and control work.Methods The quantitative cluster sampling,according to the diagnostic criteria of the development of the Pindborg,yuhu in Xiangtan city of different types of 57 units of 11 046 people to chew areca cause OSF epidemiological investigation.Results OSF 335 diagnosis example,the prevalence rate of 30.33‰,4 cases were oral cancer,oral cancer coexist rate was 11.94‰; All OSF patients had a history of betel nut,no chewing betel nut (containing the cigarette,wine,and spicy aficionados) were not found in patients with OSF; Of OSF prevalence in the chewing hobby was no differences in sex and age in the crowd; OSF prevalence of high and low with length of fixed number of year of average chewing betel nut dose and chewing betel nuts were closely related(r =0.28828,P ＜ 0.01) ; OSF prevalence was different from eating betel nut additive that had a very significant difference.Different hobbies compatibility with standardized test,7 incidence group had 6 group without significant difference,but people only eat chili can (in the control group,1 329) and outsiders no OSF patients (control group,698).Conclusions Survey results confirm that chewing betel nut is the main factor of Xiangtan people of OSF,and OSF carcinoma prevalence is lower than abroad.

Objective To investigate the effect of salvia mihiorrhiza on spinal cord ischemia reperfusion injury after surgical treatment in patients with cervical canal stenosis. Methods Retrospective analysis of 64 cases had cervical canal stenosis in the last 5 years in our hospital. Sixty-four cases were randomly divided into the salvia mihiorrhiza group(31 cases)and the control group(33 cases). The therapeutic effect was assessed using JOA grade system. Results In the salvia mihiorrhiza group,the JOA average score was 8. 8 ±2. 6 before surgical treatment, after two weeks of surgical treatment it was 13. 7 ± 2. 4. The JOA improvement ratio was (61. 5 ± 2. 9) % . In the control group,the JOA average score was 9. 1 ±2. 2 before surgical treatment,after two weeks of surgical treatment it was 13. 4 ± 2. 3. The JOA improvement ratio was (60. 5 ± 2.2)% .The JOA improvement ratio in the salvia mihiorrhiza group was significantly higher than that in the control group (P < 0. 05) . Conclusions Salvia mihiorrhiza has protective effect on spinal cord ischemia reperfusion injury.

AIM: To establish the quality standard of Shajun Zhiyang Lotion (Radix Sophorae Flavescentis, Cortex Phellodendri Chinensis, Fructus Cnidii, Borneolum Syntheticum, etc.). METHODS: Cortex Phellodendri Chinensis and Fructus Cnidii and Borneolum Syntheticum were identified by TLC. The content of matrine was determined by HPLC. RESULTS: TLC identification was highly specific and the sports were clear. The linear range for matrine was in the range of 0.295 3-2.362 0 ?g and its average recovery was 100.38% and RSD was 1.5%, respectively. CONCLUSION: The quality of Shajun Zhiyang Lotion could be controlled effectively according to the quality standard.
