AIM　To study the apoptosis-inducing and growth-inhibitory effect of rhein, an herb-derived compound, and its combination with mitomycin C (MMC) on cultured tumor cells. METHODS　MTT assays were used to determine the inhibition of proliferation by drugs in several tumor cell lines. Nucleoside transport and DNA synthesis inhibition were determined by ［3H］ thymidine transport and incorporation assays. Flow cytometry, electrophoresis on agarose gels and morphological assesment were applied to analyze the apoptotic changes. RESULTS　The IC50 values of nucleoside transport was 19.1 μg*mL-1 and that of the DNA synthesis inhibited by rhein was 27.4 μg*mL-1. In MTT assay the IC50 values of rhein for KB, hepatoma BEL-7402 and mammary carcinoma MCF-7 cells were 11.5 μg*mL-1, 14.0 μg*mL-1 and 18.4 μg*mL-1 respectively. Synergistic effect of rhein and MMC was found in all the three cell lines. As found, rhein induced apoptosis in KB cells, and the increase of apoptotic cells reached 71.0% at 96 h. The combination of rhein and MMC enhanced the induction of apoptosis significantly. CONCLUSION　These results suggest that rhein, as a biochemical modulator, might be potentially useful in cancer chemotherapy.

Objective:To observe the clinical effects of herbal cake-partitioned moxibustion in the treatment of knee osteoarthritis (KOA).
Methods:A total of 120 cases with KOA were randomly divided into two groups by the random digital table, 60 cases in each group. The herbal cake-partitioned moxibustion (HCPM) group was treated by herbal cake-partitioned moxibustion, once per day and five days per week, with ten sessions as one course. The Western medication (WM) group was treated by the oral administration of Diclofenac Sodium Sustained-release Tablets. The knee functions of the patients were assessed by Western Ontario and McMaster Universities osteoarthritis index (WOMAC) before and after the treatment. The clinical effects were observed in the two groups after four-week continuous treatment.
Results:The total effective rate was 86.7% in the HCPM group and 73.3% in the WM group. The difference in the total effective rate between the two groups was statistically significant (P<0.05). After treatment, WOMAC scores in the two groups were statistically different than those of the same group before the treatment (bothP<0.05); the difference between the two groups were statistically significant (P<0.05).
Conclusion:Herbal cake-partitioned moxibustion and oral administration of Diclofenac Sodium Sustained-release Tablets can improve the knee functions of KOA patients, but the therapeutic effect was better by herbal cake-partitioned moxibustion than by oral administration of Diclofenac Sodium Sustained-release Tablets.

Usually individualized comprehensive treatments are applied to children with cerebral palsy. Among them, Kinesio taping is a simple treatment compared to orthosis, which allows greater rang of motion (ROM) and can more easily be accepted by patients, however, its effectiveness is controversial. This article introduced the mechanism that mainly includes relieving pain, improving joint mobility, increasing strength, relieving edema and increasing proprioception. The application of it in upper limbs, lower limbs and trunk of children with cerebral palsy was discussed. Finally, the advantages and limitations of Kinesio taping, suitable types of cerebral palsy and the therapeutic evaluation were analyzed.

Aim To study the mechanism of inhibition of basic fibroblast growth factor (bFGF) related signal transduction by lidamycin in cancer cells. Methods MTT assay was used to determine the growth inhibitory effect of lidamycin (LDM) and adriamycin (ADR) in several cancer cell lines. The inhibition of bFGF bound to its receptor by LDM was measured with [ 125I ]-bFGF binding assay.Intracellular Ca2+ stimulated by bFGF was measured by Fura-3. The formation of bFGF- receptor immune complex and the inhibitory effect of LDM on the activity of PKC isoenzymes induced by bFGF in cancer cells were identified by Western blotting analysis. Results LDM displayed extremely potent growth inhibitory effect on several cancer cell lines in a dose-dependent manner. A comparison of the IC50 values showed that the effect of LDM was 1 000-fold more potent than that of ADR. LDM blocked the specific by anti-FGFR specific antibody, LDM inhibited the formation of bFGF-receptor immune complex. bFGF demonstrated that LDM inhibited the activity of PKC isoenzymes in cancer cells stimulated with bFGF.Conclusion The blocking of bFGF receptors in the signal transduction pathway may be involved in the effect of LDM on cancer cells.

AIM:To evaluate the effect of rigid gas permeable ( RGP ) lens on the tear film and the visual quality in adolescents with a double-pass system.
METHODS:This was a prospective study comprised 23 myopia patients ( 39 eyes ) wearing rigid gas permeable contact lens ( RGP ) between Jun. 2015 and Aug. 2015 in the Department of Ophthalmology of Jinling Hospital. Uncorrected visual acuity ( UCVA ) , sphere refractive, cylinder refractive, Schirmer I test, tear film break-up time ( BUT ) , the visual quality and the tear film quality with OQAS II were obtained before and 1wk, 1, 3, 6mo after wearing. The data was analyzed using t-test and One-way.
RESULTS:The UCVA in before and after 1wk, 1, 3, 6mo were 0. 23±0. 10, 0. 81±0. 23, 0. 99±0. 11, 1. 01±0. 09, 0. 95±0. 14, the difference was statistically significant ( F=723. 36, P<0.01). The sphere in before and after 1wk, 1, 3, 6mo were (-2. 83±1. 34) D, (-0. 63±0. 82) D, (-0. 12±0. 20) D, (-0. 03±0. 10 ) D, (-0. 10±0. 30 ) D respectively, the difference was statistically significant (F=107. 01, P<0. 01). The refractive cylinder in before and after 1wk, 1, 3, 6mo were (-0. 12±0. 21) D, (-0. 13±0. 22) D, (-0. 12±0. 21) D, (-0. 14±0. 26) D, (-0. 21±0. 27) D respectively, there was no significant difference before and after wearing RGP (F=2. 58, P>0. 05). Schirmer I test showed no statistically significant difference before and after wearing RGP ( F=4.88, P>0. 05). The stability of tear film was reduced after wearing RGP, and the difference was statistically significant (F=135. 11, P<0. 01). The modulate transfer function ( MTF ) cut- off frequency was reduced after wearing RGP, the object scatter index ( OSI ) was increased after wearing RGP, and the difference was statistically significant, the tear film quality OSI was increased after wearing RGP, and the difference was statistically significant (F=6. 16, 19. 23, 10. 62, P<0. 01).CONCLUSION:The UCVA is significantly increased after wearing RGP. However, there was no significant change in the base-line of tear secretion, but BUT is significantly reduced after wearing RGP. The stability of the tear film is reduced, which can lead to a decline in visual quality.
