Objective To explore the clinical and pathological features of carcinoma in bladder diverticulum,and its diagnosis and treatment. Methods This series included 5 cases of carcinomas in bladder diverticula (male,4 and female 1;mean age,73 years).Three cases were pre-operatively confirmed by biopsy with cystoscopy,and 2 were intra-operatively confirmed by frozen section of samples.Of the 5 cases,2 of transitional cell carcinoma underwent partial cystectomy;the remaining 3,each of whom had squamous cell carcinoma,adenocarcinoma and mixed carcinoma (squamous cell carcinoma and transitional cell carcinoma),underwent radical cystectomy and ileal neobladder.After operation 3 cases received chemotherapy,1 case received chemotherapy and radiotherapy. Results The 5 cases were followed up for an average of 23 months (6~72 months).Two cases of transitional cell carcinoma had relapse,and then underwent radical cystectomy and ileal neobladder.Of them 1 died of distant metastasis soon after operation,the other had survived free of tumor for 6 years since operation.The case of squamous cell carcinoma died of multiorgan metastasis 14 months after operation.The case of adenocarcinoma died of myocardial infarction 11 months after operation.The case of mixed carcinoma had survived free of tumor for 6 months since operation. Conclusions Cystoscopy and imaging play an important role in detecting tumors originating from the bladder diverticulum.Surgical operation,especially radical cystectomy,should be performed.Adjunctive therapies such as chemotherapy and radiotherapy can be conducted if necessary.

Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a hypotensive effect. The hypotensive effects of Taichong and Taixi were better than those of Taibai and the non-acupoint (P<0.05). The hypotensive effects of Taichong and Taixi were equal (P>0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

BACKGROUND: It is thought in traditional Chinese medicine that dogday moxibustion (DDM) has good clinical effect in treating bronchial asthma. Study of its influence on soluble cellular adhesion molecules in patients with bronchial asthma can help to well understand its mechanism.OBJECTIVE: To observe the effect of dog-day on soluble cellular adhesion molecules in patients with bronchial asthmaDESIGN: Self-control, case-control observationSETTING: College of Acupuncture and Manipulation and Clinic of the Department of Acupuncture and Moxibustion of the First Affiliated Hospital, Guangzhou University of Traditional Chinese Medicine.PARTICIPANTS: Totally 28 patients with bronchial asthma receiving dog-day moxibustion in the Clinic of the Department of Acupuncture and Moxibustion, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine from July to August 2004 were set as dog-day moxibustion group, and 10 concurrent health volunteers were set as normal control group.METHODS: According to the principle of "treating winter diseases in summer", the Chinese medicine which consists of such herbs as Baijiezi(Semen Sinapis Albae ), Mahuang(Herba Ephedrae ), Xixin (Herba Asari ),Gans ui (Radix Kansui ), Yanhu (Rhizoma Corydalis ) was stuck on the points such as Feishu, Dingchuan, Fengnen, Bailao, Shenshu. Point selection was at the two sides, and a lumpy salve was stuck on the point with adhesive tape. Three to six hours for adult and one to two hours for children in each sticking duration; and the operation was respectively done on the first (July20), second (July 30) and third (August 9) dog-day.MAIN OUTCOME MEASURES: Short-term effect 3 months later was observed, the levels of soluble cellular adhesion molecules and IgE were assayed before and 10 days after treatment, and comparison with normal control group was performed. The indexes of the patients before treatment were performed Pearson correlation analysis.RESULTS: Twenty-eight patients and 10 healthy persons all entered result analysis. [1] Intercellular adhesion molecule-1 level was significantly higher before treatment in dog-day moxibustion group than that after treatment in the dog-day moxibustion group and that in the normal control group [(281.39±64.58 ), (256.95±44.22), ( 194.30±39.05 ) μg/L,P < 0.01].[2]Vaso-cellular adhesion molecule-1 level was significantly higher before treatment in the dog-day moxibustion group than that after treatment in the dog-day moxibustion group and that in the normal control group [(234.79±89.75), (185.80±84.41), (128.85±51.28)μg/L,P < 0.01]. [3]IgE level was significantly higher before treatment than that after treatment in the dog-day moxibustion group and that in the normal control group [(482.61±123.43), (418.96±134.18), (161.53±43.64)μg/L,P< 0.01]. [4]Pearson correlation analysis result: Intercellular adhasion molecule-1 level is significantly positively correlated with IgE and vascular intercellular adhesion molecule-1 level (r =0.641,0.449 ,P < 0.01,0.05). [5]Effect: Total effective rate was 93% (26/28)in the treatment of bronchial asthma with dogday moxibustion . The type of the symptoms, with blister or not, course of disease and condition of disease had no significant influence on effect (P> 0.05).CONCLUSION: Dog-day moxibustion may effect through inhibiting the expression of adhesion molecule or inhibiting leukocyte to adhere endothelial cell directly so as to reduce the infiltration of inflammatory cells.

BACKGROUND: Under specially physical environment, for example weightlessness, metabolism of bone tissue may have remarkable changes; however, osteoblast is a core of bone metabolism and bone formation, so it is very sensitive to changes of gravity environment.OBJECTIVE: To observe the effects of simulated weightlessness on bone marrow stromal cell count and osteogentic capacity of weight bearing bone in rats so as to reveal the mechanism of bone loss.DESIGN : Randomized pairing and controlled study.SETTING: College of Aerospace Medicine and Department of Pathology of Stomatology College, the Fourth Military Medical University of Chinese PLA.MATERIALS: A total of 20 adult healthy male SD rats were selected in this study. At the beginning of experiment, rats based on their body mass were randomly divided into control group and suspension group with 10 in each group. Alkaline phosphatase kit was provided by Beijing Zhongsheng Bioengineering High-technological Company.METHODS: The experiment was carried out in the Department of Pathology, Collage of Stomatology, the Fourth Military Medical University of Chinese PLA from November 1999 to July 2000. Rats were randomly divided into tail suspension group and control group with 10 in each group. Rats in the tail suspension group were given tail suspension for 28 days. Their heads maintained 30° low position, and their hindlimbs freely suspended and were not given weight loading. While, rats in the control group were fed normally. At the end of experiment, bone marrow stromal cells were obtained from femur for primary and transferring cultures.MAIN OUTCOME MEASURES: Cell counting and methylthianolyldiphenyl-tetrazolium bromide (MTT) assay were used to draw growth curve of cells in primary and transferring cultures and to measure activity of alkaline phosphatase and forming quantity of mineralized nodules in vitro.RESULTS : ① Activity of alkaline phosphatase: Activity of alkaline phosphatase of cells in the primary and transferring cultures in the suspension group was lower than that in the control group, and there was significant difference between them (P<0.05). ② Forming quantity of mineralized nodules: Forming quantity of mineralized nodules in the suspension group was less than that in the control group, and there was significant difference between them (P<0.05). ③ Cell growth: Growth curve of femoral stromal cells in primary and transferring culture manifested as S. Doubling time of cells in the suspension group was similar to that in the control group. ④ Amount of bone marrow stromal cells in femur: Amount of bone marrow stromal cells in primary culture in the suspension group was decreased as 50% as that in the control group (P<0.05).CONCLUSION: Under simulated weightlessness, amount of bone marrow stromal cells decreases obviously; in addition, amount of osteoblast also decreases in weight bearing bone of hindlimbs and osteogentic capacity in vitro decreases simultaneously.

Objective To investigate the effect of laparoscopic lymphadenectomy in patients with adenocarcinoma of esophagastric junction (AEG).Methods 105 patients with AEG underwent open or laparoscopic surgery from June 2014 to September 2015 were enrolled in the study and divided into minimally invasive group (n = 70) and laparotomy group (n = 35). The baseline data, lymphadenectomy result and perioperative data were compared between the two groups.Results Total number of splenic hilar lymph nodes dissection in minimally invasive group was significantly more than that in laparotomy group (P < 0.05). But there were no significant differences in the total number of lymph node dissection, number of positive lymph node dissection, positive rate of all node, number of positive splenic hilar lymph node dissection and positive ratef of splenic hilar lymph node between two groups (P > 0.05). Operation time, intraoperative blood loss, length of incision, positive proximal margins rate, thoracoabdominal resection rate and spleen resection rate in minimally invasive group were significantly lower than that in laparotomy group, esophagus resection length was significantly bigger than that in laparotomy group (P < 0.05). No death occurred postoperatively in all patients. The time of anus exsufflation, first intake liquid diet and postoperative ambulatory episode in minimally invasive group were significantly lower than that in laparotomy group (P < 0.05). There were no significant differences in the incidence of complications between two groups (P > 0.05).Conclusions Compared with open surgery, laparoscopic surgery is superior in splenic hilar lymph nodes dissection of AEG, with longer esophageal cutting distances, lower thoracoabdominal resection and spleen resection rate. It is safe and feasible, worthy of clinical promotion.
