Objective: To observe the effects of different doses of ginger-partitioned moxibustion on serum trefoil factor 1 (TFF1) and mucin 5AC (MUC5AC) levels, as well as the expression of epidermal growth factor receptor (EGFR) in gastric mucosa of rats with spleen deficiency syndrome, therefore, to explore the possible mechanism and the dose-effect characteristics of ginger-partitioned moxibustion in spleen deficiency syndrome. Methods: Seventy-five SPF grade Sprague-Dawley (SD) rats were randomly divided into a blank control group (group A), a model group (group B), a 3 moxa-cone ginger-partitioned moxibustion group (group C1), a 6 moxa-cone ginger-partitioned moxibustion group (group C2) and a 9 moxa-cone ginger-partitioned moxibustion group (group C3) using random number table method, 15 rats in each group. Except group A, rats in the other groups received intragastric administration of 4 ℃200% concentrated Da Huang (Radix et Rhizoma Rhei) to prepare spleen deficiency syndrome model. After successful modeling, rats in group B received no treatment; rats in group C1, C2 and C3 were treated with 3, 6 and 9 moxa-cone ginger-partitioned moxibustion at Zusanli (ST 36) and Zhongwan (CV 12) respectively for 8 continuous days. The general symptom score of rats was observed. The serum levels of TFF1 and MUC5AC were detected by enzyme-linked immunosorbent assay (ELISA). The expression of EGFR protein in gastric mucosa was detected by immunohistochemistry. Results: After the treatment, compared with group A, the spleen deficiency symptom score was increased in group B, the levels of serum TFF1 and MUC5AC, the EGFR protein expression in gastric tissues of group C1, C2 and C3 were significantly increased (all P<0.01); compared with group B, the spleen deficiency scores were decreased in group C1, C2 and C3, and the serum levels of TFF1 and MUC5AC, as well as EGFR protein expression in gastric tissues were increased (all P<0.01). Compared with group C1, the spleen deficiency scores were decreased in group C2 and C3, the serum levels of TFF1 and MUC5AC, and the expression of EGFR protein in gastric tissues were increased (all P<0.01), however, there was no significant difference between group C2 and C3 (all P>0.05). The mechanism may be related to the increase of serum TFF1 and MUC5AC levels and activation of EGFR protein. Conclusion: Ginger-partitioned moxibustion can improve the symptoms, as well as promote the proliferation and repair of gastric mucosa in rats with spleen deficiency. The therapeutic efficacy of 6 or 9 moxa-cone ginger-partitioned moxibustion is better than that of 3 moxa-cone ginger-partitioned moxibustion, while the efficacies are equivalent between 6 and 9 moxa-cone ginger-partitioned moxibustion groups.

OBJECTIVETo observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

METHODSTotally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated.

RESULTSThe percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05].

CONCLUSIONDOL combined WM was superior to KOL in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

Objective To observe effects of different dosages of moxibustion with ginger-separated moxibustion on expressions of mitogen extracellular kinase (MEK) 1/2 and extracellular regulated protein kinase (ERK) 1/2 of gastric tissue in rats with spleen deficiency; To explore the possible mechanism and the dose-effect relationship. Methods Seventy-five SD rats were randomly divided into blank control group, model group, ginger-separated moxibustion for three zhuang group, six zhuang group and nine zhuang group according to random digits table method, with fifteen rats in each group. The rat model of spleen deficiency was established by intragastric administration with 200% Rhei Radix et Rhizoma infusion at 4 ℃. Ginger-separated moxibustion groups were treated with different dosage of moxibustion at "Zusanli", "Zhongwan" for eight days after the modeling. Pathological changes of gastric tissue by HE staining were observed under light microscope, and immunohistochemistry was used to detect the expressions of MEK1/2 and ERK1/2 protein in gastric tissue of rats. Results Compared with the blank control group rats, the gastric mucosa injury in the model group was obvious, which showed that the damage and abscission was more serious; compared with the model group, the gastric mucosa of rats was partly exfoliated and the damage was improved in three zhuang group, and the surface of gastric mucosa of rats was more complete and damage was improved obviously in six zhuang group and nine zhuang group; compared with the blank control group, the expressions of MEK1/2 and ERK1/2 protein in gastric tissue increased obviously in other groups (P<0.01);compared with three zhuang group, the expressions of MEK1/2 and ERK1/2 protein in gastric tissue increased in six zhuang group and nine zhuang group (P<0.01), but the effects of the two group were similar, without statistical significance (P>0.05). Conclusion Ginger-separated moxibustion can repair gastric mucosa in rats with spleen deficiency, which may be closely associated with its effect in increasing the expressions of MEK1/2 and ERK1/2 protein in gastric tissue and activating the MEK/ERK signal transduction pathway.

Objective To evaluate the feasibility of laparoscopically robotic assisted radical hysterectomy and pelvic lymphadenectomy in treatment of cervical cancer.Methods From Dec.2008 to Aug.2009,5 cervical cancer patients at stage Ⅰ bl to Ⅱ a underwent laparoscopically robotic assisted radical hysterectomy and pelvic lymphadenectomy.The following clinical parameters were recorded and compared,including operative time,blood loss,intraoperative and postoperative complications,the changes of hemoglobin before and after surgery,postoperative temperature,the time of postoperative anus exhaust and urination,hospitalization,pathologic exam,and the number of lymph nodes.Results Laparoscopically robotic assisted radical hysterectomy and pelvic lymphadenectomy were performed successfully on those 5 patients without the conversion to laparotomy.No intraoperative and postoperative complications were observed.The operative time were 305,365,275,240 and 245 minutes,respectively,with a mean value of 286 minutes.Estimated blood loss was 200,400,650,300 and 400 ml,respectively.The mean blood loss was 390 ml.Temperatures of all patients were not higher than 37.5℃ and anus exhaust was recovered at 36 hours after surgery.Those five patients were hospitalized for 11,13,9,12 and 12 days respectively.Squamous carcinoma of cervix were diagnosed by the pathologic examination.The resected margin of vagina and parametrium was clear.The numbers of pelvic lymph nodes were 14,22,16,21 and 18,respectively.No evidence of lymph nodes metastasis was found.Conclusion Laparoscopically robotic assisted radical hysterectomy and pelvic lymphadenectomy is feasible as a novel approach in the treatment of cervical cancer.

The present study investigated the relationship between DNA-dependent protein kinase (DNA-PK) and radiosensitivity of nasopharyngeal carcinoma (NPC) cell lines. The dose-survival relationship for NPC cell lines, CNE1 and CNE2, was analyzed using clonogenic formation assay, the activity of DNA-PK of the two cell lines was measured using the Signa TECT DNA-PK assay kit, and the localization and expression of Kus (a heterodimer) and DNA-PKcs protein in CNE1 and CNE2 before irradiation and 15 min, 1 h, 6 h, 12 h, 24 h after 4 Gy irradiation were analyzed by immunofluorescence, laser scanning confocal microscope (LSCM) and Western blot. The results showed that the surviving fraction of CNE1 was higher than that of CNE2 at each dose. The DNA-PK activity of CNE1 was also significantly higher than that of CNE2 before and after irradiation (P<0.05), while the expression of total Ku70/Ku80 in CNE1 and CNE2 had no significant difference. Increasing translocation of Ku70 and Ku80 from the cytoplasm to the nuclei in the two cell lines was observed with increase of irradiation time as detected by Western blot, and the immunofluorescence of the DNA-PK complex subunits showed greater nuclear translocation in CNE1 than CNE2 after irradiation. The results suggest that the relatively higher radio-resistance of CNE1 correlates with the higher activity of DNA-PK as compared to that of more radiosensitive CNE2 (or lower radio-resistance) before and after irradiation. Thus, DNA-PK activity may be a useful predictor of radiosensitivity of NPC.
