OBJECTIVETo study the effects of modified Huopo Xialing Decoction (HXD) in treating patients of Pi-Wei dampness-heat syndrome (PWDHS) and its impact on epithelial cell apoptosis of tongue.

METHODSFifty patients with PWDHD were randomized depending on their visiting sequence into two groups, the 30 patients in the treatment group treated with HXD and the 20 in the control group treated with Domperidone. The therapeutic course for both groups was 2 weeks. Besides, a normal control group consisting of 30 healthy volunteers was set up. The changes of tongue fur, grade of major syndromes in different groups were observed and scored before and after treatment to evaluate the therapeutic effectiveness, and the apoptotic index (AI) was estimated using TUNEL technique.

RESULTSAI in the two patient groups before treatment was obviously lower than that in the normal group (P < 0.01 or P < 0.05); after treatment, AI in the treatment group increased significantly (P < 0.01), with no difference from that in the normal group (P > 0.05), while in the control group, it only showed a slight trend of increasing. Similar outcome of tongue fur grades was seen in the two groups, it was improved significantly (P < 0.01) in the treatment group but insignificantly in the control group (P > 0.05). After treatment, syndrome scores were both lower in the two groups (P < 0.01), but the decrement in the treatment group was more significant than that in the control group (P < 0.01). Comparison between groups showed that the total effective rate in the treatment group was significantly superior to that in the control group (90% vs 65%, P < 0.01).

CONCLUSIONHXD has good clinical efficacy in treating PWDHS, and has good effect in alleviating the greasy yellow tongue fur in patients with PWDHS by accelerating the tongue epithelial cell apoptosis.

BACKGROUNDRoundabout 5 (R5) is a monoclonal antibody which can neutralize the binding of Roundabout 1 (Robo1) to Slit2. Oral squamous cell carcinoma angiogenesis was significantly inhibited when R5 blocked slit-robo signaling pathway. However, the effect of R5 on the invasion of tongue cancer cells has not been investigated clearly.

METHODSIn this study, we treated human brain metastasis of tongue cancer cell lines (Tb cells) with R5 at different concentrations, and the control Tb cells were treated with 10 mg/ml immunoglobin G 2b (IgG2b). The effect of R5 on the proliferation, adhension, invasion and motility of Tb cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, cell attachment assay on fibronectin (FN), wound assay and chemotaxis assay, respectively. And gelatin-incorporated sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was used to investigate the activity of matrix metalloproteinase-2 (MMP2) and matrix metalloproteinase-9 (MMP9).

RESULTSR5 had no effect on the proliferation of Tb cells. However, R5 could significantly inhibit the motility, attachment and chemotaxis of Tb cells to FN, and it could also significantly inhibit the activity of MMP2 and MMP9 in Tb cells.

CONCLUSIONR5 can inhibit the adhesion, invasion and motility of human tongue carcinoma Tb cells.

OBJECTIVETo investigate the effect of celecoxib on the cell cycle and apoptosis in human tongue squamous cell carcinoma (HTSCC) cell line Tca8113.

METHODSTca8113 cell line was cultured in the presence of different concentrations of celecoxib. MTT assay was used to measure cell survival rate, and flow cytometry performed to analyze the cell cycle distribution. Annexin V-FITC/PI staining was used to detect the early changes of apoptosis, and transmission electron microscope employed to observe the ultrastructural changes of the apoptotic cells.

RESULTSCelecoxib inhibited the proliferation of Tca8113 cells in a dose-dependent manner, the effect of which was mediated by inducing cell cycle arrest mainly in G1/S phase. Flow cytometry and ultrastructural observation demonstrated an early to late stage changes of the apoptotic cells exposed to increased concentrations of celecoxib.

CONCLUSIONCelecoxib dose-dependently inhibits the proliferation of Tca8113 cells by causing cell cycle arrest and inducing apoptosis.

PURPOSE: The purpose of this study was to examine the effects of using gauze frozen with normal saline or ice on thirst-relief and oral condition of laparoscopic cholecystectomy patients. METHODS: A quasi-experimental nonequivalent control group, pretest-posttest design was used. Participants (n=53) received either gauze frozen with normal saline (n=17), ice (n=18) or wet gauze (n=18) for thirst-relief. The subjective thirst level and oral condition of the participants were assessed before the intervention, 15 min after the first intervention and 15 min after the second intervention. RESULTS: After oral care was provided twice, there were significant differences in thirst level among the groups. When oral care was provided twice, the oral condition of tongue, saliva, mucosal membrane, and gingiva was improved in patients receiving gauze frozen with normal saline or ice. CONCLUSION: Gauze frozen with normal saline and ice can be effective for oral care in reducing the thirst level and improving the condition of the oral cavity.

OBJECTIVETo investigate the role of COX-2 inhibitor celecoxib in inhibiting the migration of human tongue squamous cell carcinoma Tca8113 cells.

METHODSThe effects of celecoxib on Tca8113 cell migration were tested using scrape motility assay, cell-matrix adhesion assay and Boyden chamber motility assay.

RESULTSFollowing a 24-hour incubation with 10 and 20 micromol/L celecoxib, the migration of Tca8113 cells was significantly decreased (Plt;0.05). Celecoxib treatment for 24 h also resulted in significantly decreased adhesion of Tca8113 cells on Fn-coated surface in a dose-dependent manner.

CONCLUSIONCOX-2 inhibitor celecoxib can inhibit Tca8113 cell migration, the mechanism of which awaits further investigation.

AIMTo investigate the effect of DAPT (gamma-secretase inhibitor) on the growth of human tongue carcinoma cells and to determine the molecular mechanism to enable the potential application of DAPT to the treatment of tongue carcinoma.

METHODOLOGYHuman tongue carcinoma Tca8113 cells were cultured with DAPT. Cell growth was determined using Indigotic Reduction method. The cell cycle and apoptosis were analyzed by flow cytometry. Real-time PCR and Immuno-Fluorescence (IF) were employed to determine the intracellular expression levels.

RESULTSDAPT inhibited the growth of human tongue carcinoma Tca8113 cells by inducing G0-G1 cell cycle arrest and apoptosis. The mRNA levels of Hairy/Enhancer of Split-1 (Hes-1), a target of Notch activation, were reduced by DAPT in a dose-dependent manner. Coincident with this observation, DAPT induced a dose-dependent promotion of constitutive Caspase-3 in Tca8113 cells.

CONCLUSIONDAPT may have a therapeutic value for human tongue carcinoma. Moreover, the effects of DAPT in tumor inhibition may arise partly via the modulation of Notch-1 and Caspase-3.

OBJECTIVETo explore gene expression of estrogen receptor (ERalpha, ERbeta) and androgen receptor (AR) in genioglossal muscle (GG) of adult male rats, and to investigate the effects of sex hormones on GG activities, ERalpha, ERbeta and AR expression.

METHODSGG samples were collected from 10 healthy adult male rats. Total RNA were extracted and subjected to fluorescent quantitative reverse transcription-polymerase chain reaction (FQ RT-PCR) for quantitative measurement of ERalpha, ERbeta and AR mRNAs. The other 24 male rats were randomly divided into 3 groups: control group, estrogen group (intramuscular injection of estrogen 0.1 mg/kg, twice a week) and androgen group (intramuscular injection of androgen 2.5 mg/kg, twice a week). The electromyographic activities (EMG) and contract tension of GG were investigated after 4-week treatment. The expression of ERalpha, ERbeta and AR was assessed by Western blot.

RESULTSThe mRNA expression ratios of AR/GAPDH, ERalpha/GAPDH, ERbeta/GAPDH and ERalpha/ERbeta were (295.80 +/- 127.20), (2042.00 +/- 921.57), (65.96 +/- 29.57) and (36.83 +/- 19.66), respectively. The mRNA level of ERalpha was significantly higher than that of ERbeta (P < 0.01). Compared with the control group, the EMG of GG was intensified in the estrogen group (P < 0.01). GG contractility did not change significantly (P > 0.05), and ERalpha expression in GG was up-regulated by estrogen (P < 0.05); while in the androgen group, the EMG of GG was weakened (P < 0.05). P(t) and P(0) were slightly increased (P > 0.05) and the decline rate of P(0) was markedly quickened (P < 0.05). AR and ERbeta expressions were down-regulated by androgen (P < 0.05).

CONCLUSIONSBoth AR and ER were expressed in GG of adult male rats, and ERalpha was expressed more abundantly than ERbeta. Estrogen could greatly improve activities of GG and stimulate the expression of ERalpha. Whereas, androgen could restrain activities of GG, impair its fatigue resistance capacity and inhibit the expression of AR and ERbeta.

OBJECTIVETo explore the effect of Chinese herbs during the perioperative period of laparoscopic cholecystectomy (LC).

METHODSThree hundred and sixty patients of chronic lithic cholecystitis (LCCT) were randomly assigned to two groups by lottery, 180 patients in each group. During the peri-operative period, the control group was treated with conventional Western medicine and placebo. The treated group was given the same conventional Western medicine and Chinese herbal decoctions, with Shitong mixture No. 1 added before LC, and Liujunzi decoction added after LC for three days. The operation time, body temperature after LC, white blood cell count, wind-breaking time after operation, as well as the changes of tongue coating in the first three post-operative days were recorded.

RESULTSThere was no significant difference between the two groups in operation time (P>0.05), while the improvement in body temperature recovery, wind-breaking time and changes of tongue coating in the treated group were better than those in the control group (P<0.01).

CONCLUSIONApplying Chinese herbs during perioperative period of LC could effectively benefit early recovery in such patients.

OBJECTIVETo observe the apoptosis induced by exogenous NO in Tca8113 cells and to investigate the possible mechanism.

METHODSSNP as NO donor was used to treat the tongue squamous cell carcinoma Tca8113 cells. Cytotoxic and apoptotic effects of NO on Tca8113 cells were examined by using MTT assay, acridine orange (AO) staining, Wright-Giemsa staining, agarose gel electrophoresis and flow cytometry. Western blot was performed for investigating the apoptotic mechanism.

RESULTSNO had a remarkable proliferation inhibiting effect on Tca8113 cells. After being exposed to exogenous NO, Tca8113 cells showed series of apoptotic morphological changes such as cell shrinkage, nuclear condensation; and also showed DNA fragmentation, G2/M phase arrest as well as upregulation of the tumor suppressor P53 protein.

CONCLUSIONExogenous NO has a proliferation inhibition and apoptosis induction effect on Tca8113 cells in a concentration and time-dependent manner, P53 protein may be involved in the apoptosis induced by NO.
