Objective To investigate the role of new contrast agent and real time gray scale contrast tuned imaging in the evaluation of the perfusion and echogenicity of liver neoplasms and to discuss the diagnostic value.Methods Thirty five patients with unconfirmed liver neoplasms were enrolled in the study.Nine of them were diagnosed clinically,while the other 26 cases with pathological evidence through surgery or needle biopsy.Contrast agent SonoVue,Technos DU6 and CnTI technology were used.The contrast agents were delivered intravenously or through bolus injection.Results Timing of all phases following contrast injection in normal and cirrhotic liver was observed.And then the perfusion processs of liver neoplasms was recorded.Among the 23 cases of typical hepatocellular carcinoma(HCC),21 cases(91%) presented with early artery enhancement and immediate wash out,while the other 2 cases of small(
2.Analysis of questionnaire and clinical characteristics of 2,000 cases of dysmenorrheal.
China Journal of Chinese Materia Medica 2015;40(20):3920-3924
Through the questionnaire survey of 2,000 patients with dysmenorrhea, the clinical characteristics of dysmenorrhea were investigated, and the reference basis for preventing and controlling dysmenorrhea was provided. The results found that the age of menarche, short menstrual cycle, by volume, long period of time has no obvious relationship with the occurrence of dysmenorrhea. Dysmenorrhea main influence factors to feel cold; syndrome (symptoms) characteristics for the actual situation inclusions mainly, with severity, deficiency symptoms more obvious; in different degrees of dysmenorrhea, frequency of belly chills symptoms appear most, and cold coagulation and blood stasis syndrome (symptoms) appear higher frequency; The type of cold coagulation and blood stasis dysmenorrhea was 53.2%. Dysmenorrhea measures to select bed rest most, accounting for 79.6%. For severe dysmenorrhea in patients with drug choice to traditional Chinese combined with western medicine accounted for 43.4%. Selection of Chinese medicine formulations in patients with dysmenorrhea Decoction formulation accounted for the most 26.5%. The survey results, to avoid cold and have a positive effect on the prevention of dysmenorrhea, dysmenorrhea treatment should pay attention to warming channels to dispel cold.

4.Discussion on strategy of treatment of perimenopausal syndrome with Chinese and Western Medicine.
China Journal of Chinese Materia Medica 2015;40(20):3899-3906
Perimenopausal syndrome refers to a series of physical and mental symptoms ,caused by the fluctuation of the sex hormones in the menopause, which is one of the common diseases in gynecology. With the acceleration of the aging population ir the world, it has caused the world's attention. Modern medicine has developed rapidly in the field of basic theory and clinical research, but there are still some problems in the treatment. Clinical treatment is mainly in hormone replacement therapy, but there are some potential risks, adverse reactions and many contraindications, thereby reducing patients' compliance and tolerance. Traditional Chinese medicine under the guidance of the concept of wholism cure perimenopausal syndrome based on syndrome differentiation, which has unique advantages, such as a variety of ways, less side effect, curative effect, which was patients more and more welcome. It is very important for the study to explore the perimenopausal syndrome.

5. The mechanism, critical technology and progress of osmotic drug delivery systems
Journal of International Pharmaceutical Research 2010;37(2):92-97
As the typical example of controlled release preparation, osmotic pump-controlled release preparation is a new technique of preparation characterized by zero order release kinetics. Osmotic pressure is the motivation for releasing drug. The release behavior of osmotically controlled release systems is independent of external pH and food, and the in vivo-in vitro correlation is good, so they have attracted wide attention at home and abroad. After years of development, with the constant innovation of the mechanism, the structure of the osmotic pump has been continuously improved, and many products have been marketed. In this article, the development history and the mechanism of osmotic pump-controlled release preparation are briefly reviewed. Based on solubility, osmotic pressure, the delivery orifice and the coating membrane, the critical factors affecting the release rate and the research progress on osmotic pump controled release preparation are mainly discussed.

Chinese Journal of Dermatology 1994;0(06):-
Objective To study the prevalence of atopic dermatitis (AD) in China. Method School children aged 6~ 20 were surveyed with questionnaire in different areas in our country. Results This survey was carried out in 22 cities and rural areas, distributed in 11 provinces. There were 548 AD patients( 347 males and 201 females) in a total population of 78 586. The total standardized prevalence (SP) was 0.69% . The SPs of the males and the females were 0.84% and 0.51% , respectively, the difference being statistically significant(P

4 cm in diameter(Z=1.966,P=0.048).A positive relation was seen between HSP70 expression and CD8~+ T cell number at the border zone of RFA sphere(r=0.489,P=0.046).The HSP70 expression and the CD8~+ T cell number at the border zone of RFA sphere were higher in recurrence-free patients than in recurrent patients,respectively(Z=2.009,P=0.045;Z=2.007,P=0.045).Conclusions Following the RFA,the HSP70 expression and the CD8~+ T cell number at the border zone of RFA sphere will be elevated,indicating that RFA induces an immune response against tumor antigens and a tumor-specific T cell reaction.

Objective To develop a protocol for ultrasound-guided percutaneous radiofrequency ablation (RFA) on hepatic tumors larger than 3.5 cm in diameter, and to evaluate its role in ablation treatment. Methods Mathematical analysis was performed to generate the preoperative protocol which included the least ablation (sphere) number and the optimal overlapping mode and procedure for adequately ablating a large and spherical target lesion. The target ablation volume consisted of a tumor plus a 0.5- 1.0 cm tumor-free margin. The operation method for electrode placement was also described. Based on this mathematical protocol, 113 patients with 124 hepatic tumors [( 4.75? 0.92)cm in diameter, ranging from 3.6- 7.0 cm] were enrolled and treated. Seventy-one patients had 76 primary and 42 had 48 metastatic hepatic tumors. Results Totally 554 ablations (electrode placements) were performed in 124 tumors. The tumor complete necrosis rate was 87.9% (109/124), the local recurrence rate 24.2% (30/124), the estimated mean time to local recurrence 17.3 months. Twenty-five patients had received 38 retreatments for the local recurrence (17 received one time, and 8 received two or three times). Major complications were found in 7 patients (6.2 %). Of them, only one patient who suffered from colon perforation one week after RFA treatment required surgical intervention. Conclusions A theoretic basis and clinical guidance in RFA of hepatic tumors larger than 3.5 cm might be provided. Treatment results indicated that the protocol might probably be used to improve complete necrosis rate and reduce local recurrence rate in ablation therapy. The protocol was firmed effective and feasible.

Objective To investigate the clinical role of a combination therapy of percutaneous radiofrequency ablation(RFA) and transcatheter arterial chemoembolization(TACE) in large hepatic tumors. Methods Out of 62 patients with hepatocellular carcinomas confirmed by pathology, 21 patients received a combination therapy of TACE and RFA(combination group), 22 patients TACE therapy alone, and the rest 19 patients RFA therapy alone. A total of 106 tumors with a mean diameter of ( 5.9? 0.7) cm(ranged from 5.0 to 8.1 cm) were detected, and the largest tumor was selected for observation in a patient with multiple lesions. There was no significant difference in mean age, tumor size and liver function grade among the three groups.Results Tumor complete necrosis accounted for 80.9%in combination group, which was significantly higher than that of TACE group and RFA group ( 27.2%, 47.4%,P 0.05). Mean survival duration of combination group was 25.6 months, significantly higher than that of TACE group( 14.9 months)(P0.05). Conclusions Compared with TACE or RFA therapy alone, the combination therapy improves tumor complete necrosis rate and prolongs the patients′ survival duration.
