China Pharmacy 2001;0(10):-
OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P
4.The applications of vaginal hysterectomy of non-prolapsed uterus lesion in primary hospital
Chinese Journal of Primary Medicine and Pharmacy 2011;18(4):491-492
ObjectiveTo explore the application value and techniques of vaginal hysterectomy of non-prolapsed uterus lesion in primary hospital. Methods140 cases who suffered from uterine fibroid without adhesion,glandular fibroids,functional bleeding without uterine prolapse and malignant disease were selected and divided into observation group(80 cases with vaginal hysterectomy)and control group(60 cases with routine abdominal hysterectomy).Then the clinical treatment effect was analyzed. ResultsCompared with control group,peri-operative bleeding (150 ±23)ml vs(243 ±41)ml,operation time(65 ± 14.0)min vs(90 ± 27.0)min,body temperature recovery time (3 ±0.5)d vs(4 ±0.8)d,anus exhaust time(14 ± 1.8)h vs(26 ±2.7)h,the length of time(5 ±0.8)d vs(11 ±2.9)d in observation group were all reduced,differences were significant(all P<0.01)and no case was transferred to opening appendectomy. ConclusionFor these disease including uterine fibroids with no adhesion,glandular fibroid uterine bleeding,the vaginal hysterectomy was safe and feasible,and had the advantage of smaller trauma,less bleeding,shorter hospitalization time,faster recovery etc.It was worthy to be popularized in primary hospital.
5.Immediate early genes and vocal learning and memory in songbirds
Chinese Journal of Tissue Engineering Research 2005;9(40):174-176
BACKGROUND: As demonstrated by recent reports, immediate early genes (IEGs) are rapidly induced and expressed when a songbird is stimulated either by bird-song or by its vocal-behavior. The expression area and level of IEGs in the brain, such as zenk, c-fos and c-jun, are corresponding to where and how the neurons are related as a songbird is stimulated, suggesting that IEGs play important roles in vocal learning and memory.OBJECTIVE: To study the relation between vocal learning of songbird and immediate early gene so as to understand the mechanism of human language and the control of central nervous system.DATA SOURCES: All papers were cited from MEDLINE with the keywords of "songbird, vocal learning, memory, zenk, c-fos and c-jun" in English between January 1990 and December 2001. Meanwhile, we searched the Chinese journals full-text database and Wanfang database with the same keywords in Chinese between January 1990 and November 2001 were also searched.STUDY SELECTION: The papers about immediate early genes and vocal learning and memory in songbirds were selected. Then non-randomly controlled studies were excluded, and the rest full-text papers were looked up.DATA EXTRACTION: Totally 17 papers about immediate early genes and vocal learning and memory in songbirds were found. We choose 11 papers in them and 6 was excluded because of summarization.DATA SYNTHESIS: ① zenk and vocal behavior: Expression of zenk in bird's brain can affect learning and memory through adjusting synthesis of special protein. ② Reaction of c-fos to various songs: The reaction of local neurons in bird's brain to the birdsongs are made by the decision of the numbers of song factor in learning songs. ③ Associations of c-jun and cfos: zenk, fos and jun are the necessaries for maintaining long-term memory, which produce a marked effect through signal transduction, reconstruction, synthesis and transduction of induced synapse.CONCLUSION: Immediate early genes (IEGs) are rapidly induced and expressed when a songbird is stimulated either by bird-song or by its vocal-behavior. The expression area and level of IEGs in the brain, such as zenk, c-fos and c-jun, are corresponding to where and how the neurons are related as a songbird is stimulated, suggesting that IEGs play important roles in vocal learning and memory.
6.Mesenchymal stem cells as carriers in cancer therapy
Journal of International Oncology 2012;39(10):748-751
Mesenchymal stem cells(MSCs) can directly act on tumor cells to inhibit their growth,and could also migrate to the tissue lesions and tumor tissues to transfer and express many kinds of anti-cancer factors.Numerous researches have applied MSCs as carriers of drugs to induce apoptosis,inhibit differentiation of tumor cells and inhibit tumor angiogenesis,and have got outstanding antitumor results.
7.Blarmonious society calls for health manggement
Chinese Journal of Hospital Administration 2008;24(9):626-628
Health management is the intrinsic requirement to build and embody a harmonious society. While health management provides strong human resources for the development of a harmonious society, a harmonious society promotes the health management. Health management plays a significant role in the construction and development of a harmonious society in terms of reducing risks to the health, improving the quality of life, lowering medical cost, lightening the socio-medical burden, enhancing awareness of health, improving the national health conditions, protecting health resources, and promoting a sustainable social development. Health is an important component of social productive forces, and health management is an essential prerequisite for the harmonious development of society. There would be no real harmonious society without effective health management.
8.Continuous passive joint motion following total knee replacement: 48 cases analysis
Chinese Journal of Tissue Engineering Research 2010;14(4):665-668
BACKGROUND: Early rehabilitation following total knee replacement has arisen more attention. The aim of continuous passive joint motion is to recover knee function, prevent anchylosis, accelerate blood and synovia circulation, therefore, enhance tissue repair. OBJECTIVE: To evaluate the efficacy of continuous passive joint motion following total knee replacement. METHODS: Totally 48 patients, who underwent artificial total knee arthroplasty at the Department of Orthopedics, Center Hospital of Minhang District, Shanghai Ruikang Hospital Group and Department of Rehabilitation Medicine, 309~(th) Hospital of Chinese PLA between December 2007 and October 2009 were selected. The patients were randomly divided into the experimental and control groups, with 24 cases in each group. The isometric contraction of qudraceps muscles, combined with physical agent assistant, was performed prior to total knee replacement. Patients in the experimental group was received continuous passive joint motion training at day 2 after operation, with 5°-10°increasing per day. Patients in the control group were treated with conventional methods. The knee functional score, and visual analog scale (VAS) was performed to evaluate knee functions and pains, in addition, perimeter between two legs; and range of motion were measured. RESULTS AND CONCLUSION: The knee functional score, VAS, perimeter between two legs, and range of motion were similar prior to and after total knee replacement (P > 0.05). Compared to the control group, the knee functional score of the experimental group was dramatically increased at days 3 and weeks 2 after operation (P < 0.01), the VAS and perimeter between two legs were significantly declined (P < 0.01), the range of motion was obvious improved after replacement, with greater excellent rate (P < 0.01). There was no deep venous thrombosis or infections. The results demonstrated that early rehabilitation following knee replacement is conductive to easing pain, eliminating swelling, and enhancing knee stability.
9.Splenic radiofrequency ablation for the treatment of hypersplenism due to portal hypertension: recent progress in clinical research
Journal of Interventional Radiology 2009;18(12):953-956
Splenic radiofrequency ablation (RFA) is a safe, effective and minimally-invasive approach for the management of hypersplenism due to portal hypertension. After RFA, the remnant volume of the spleen will be decreased, the hypersplenism can be corrected, and the hepatic artery blood flow can be significantly increased with resultant marked improvement of liver function; in addition, hypertrophy and regeneration of the liver can be induced. However, many factors can affect the therapeutic results of RFA,therefore, further studies are necessary to clarify the underlying mechanisms.
