The Document Retrieval Center of TCM, founded in 1992, plays an important role in the novelty retrieval of TCM scientific researching projects and clinic researches. But there are still some problems needed to be improved. The author suggests that relative governmental agents and staffs who engage in novelty retrieval should think highly of the novelty retieval of TCM to establish and consummate relative rules and regulations in order to provide the qualified services.

This paper expounds the needs analysis and system design of traditional Chinese medical science and technology of sci-tech novelty search management system,discusses the architecture of the system and each functional module,and summarizes and discusses the meaning of this system when applied in sci-tech novelty search.

Recently, herbal medicine including traditional Chinese medicine (TCM) has gained huge attention in the world. In 2015, the global trades of herbal medicine reached 93.15 billion US dollars. And, the latest statistics from the Ministry of Industry and Information Technology of People's Republic of China showed that total sales of Chinese patent medicine and raw herbs reached 120 billion US dollars in 2014. Therefore, the aim of this study was to analyze the situation of international marketing on herbal medicine and how much TCM shared in it. The PubMed database, search engines and government websites and research reports were searched for analyses. The results showed that total trades of TCM products in both domestic and foreign markets, were about 135 billion US dollars, including Chinese patent medicine, raw herbs, herbal extracts, herbal health care products, whose proportion of the global marketing was 80%.

ObjectiveTo investigate the etiology and management of male urethral stricture at 8 medical centers in China during the period from 2004 to 2009 years,and to investigate whether there were any changes in etiology and management of urethral stricture with time change.MethodsThe database on 3455 male patients with urethral stricture who underwent treatment at 8 medical centers in China between January 2004 and December 2009 were prospectively collected.The databases were analyzed for possible cause of stricture and treatment techniques for urethral stricture,and for the changes in etiology and management with time change.ResultsThere were 3455 operations for urethral stricture during the study period.The main causes of urethral strictures were traumas in 1833 patients (53.05％),among which pelvic fractures were in 1327 (38.41％) and perineal trauma in 506 (14.65％).The second cause was iatrogenic causes in 1181 patients (34.18％ ),among which transurethral operations or examinations were in 602 (17.42％),hypospadias surgery in 291 (8.42％) and urethral catheterization in 164 (4.75％ ).Less common causes were urethritis in 201 patients (5.82％),lichen sclerosus in 149 (4.31％),undefined in 91 (2.63％).The treatments of urethral strictures were endourological surgery including internal urethrotomy and dilation and open urethroplasty including end-to-end urethroplasty and the substitude urethroplasty etc.The ratios of using various techniques in total number of patients were obviously different by time.The most application technique for treatment of urethral stricture was endourological surgery ( 709 ) during 2004 -2006 and occupied 52.67％ in total number of patients.It was gradually decreased during 2007 -2009 (726) and only occupied 34.42％ (P ＜0.01 ).Open urethroplasty gradually increased during 2007 -2009 ( 1243,58.94％ ) compared with the first three years (563,41.83％ ) (P ＜ 0.01 ). Conclusions During the recent years there was an increase in the incidence of urethral stricture being trauma and iatrogenic causes.The main treatments of urethral strictures were endourological surgery and open urethroplasty.Endourological surgery was significantly decreased in total number of patients,while open urethroplasty were significantly increased during the late three years.

Objective:To observe the efficacy of cosmetic suturing techniques combined with topical recombinant human basic fibroblast growth factor (rh-bFGF) in repairing facial trauma.Methods:A prospective study was conducted on 140 patients with facial trauma admitted to the Department of Burn and Plastic Surgery, Northern Jiangsu People＇s Hospital from January to December 2022. Patients were divided into two groups based on different treatment methods using a random number table method: treatment group (70 cases), including 38 males and 32 females aged 3 to 54 (23.1±8.2) years, received cosmetic suturing techniques combined with topical rh-bFGF for wound repair; control group (70 cases), including 36 males and 34 females aged 2 to 49 (22.3±7.5) years, only received cosmetic suturing techniques for wound repair. Patients were followed up 2 weeks post-surgery to evaluate wound healing quality. Patient satisfaction was assessed using the visual analogue scale (VAS). Six months post-surgery, scar conditions were evaluated using the Vancouver scar scale (VSS).Results:In the treatment group, 65 cases were directly sutured, and 5 cases were repaired with skin flaps, with a first-class healing rate of 100% (70/70). In the control group, 66 cases were directly sutured, and 4 cases were repaired with skin flaps, with a first-class healing rate of 91.4% (64/70). The first-class healing rate in the treatment group was higher than that in the control group, with a statistically significant difference ( P=0.037). Two weeks post-surgery, the VAS score for surgical satisfaction in the treatment group was (1.13±0.52) scores, which was lower than that in the control group (2.56±1.32) scores, with a statistically significant difference ( P<0.001). Six months post-surgery, the VSS score for the treatment group was (2.49±1.27) scores, which was lower than that in the control group (4.67±1.93) scores, with a statistically significant difference ( P<0.001). Conclusions:In repairing facial trauma, the combination of cosmetic suturing techniques and topical rh-bFGF can improve wound healing quality, reduce wound scarring, and enhance patient satisfaction with surgery.

Objective To evaluate the value of 2012 classification criteria for early rheumatoid arthritis (ERA),2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria,and 1987 ACR classification criteria in the diagnosis of early rheumatoid arthritis (RA).Methods Patients who had at least one swollen and tender joint with disease duration no more than 2 years,and age more than 16 years were enrolled.The patients were diagnosed as RA or other non-RA by 2 experienced rheumatologists.The clinical and laboratory parameters were recorded.The sensitivity and specificity of three RA classification criteria were compared by McNemar test,The areas under the receiver operating characteristic curve (ROC) curve (AUC) of each RA classification criteria were analyzed using MedCalc software.Results Atotal of 310 patients were enrolled in this study,including 182ERA and 128 non-RA.The sensitivity(88.5％) of ERA criteria was much higher than that of the 1987 ACR criteria (45.6％,x2=75.013,P＜0.05),and not significantly different with the 2010 ACR/EULAR criteria (91.8％,X2=1.042,P＞0.05).The specificity of ERA criteria (91.4％) of 2010 ACR/EULAR criteria (87.5％,x2=1.8,P＞0.05) was similar to that of the 1987 ACR criteria (96.1％,x2=3.1,P＞0.05).The AUC of ERA criteria was 0.962 [95％CI(0.934,0.980)],which was slightly better than that of the 2010 ACR/EULAR criteria 0.959 [95％CI(0.931,0.978)],Z=0.380,P=0.7038,and much higher than that of the 1987 ACR criteria 0.885 [95％CI (0.845,0.919)],Z=4.517,P＜0.01.Conclusion Overall evaluation,the diagnostic value of ERA criteria is better than 1987 ACR and 2010 ACR/EULAR criteria in early rheumatoid arthritis.Compared to 2010 ACR/EULAR classification criteria,ERA criteria is more simple and practical.
