Objective To investigate the clinical efficacy of combination of umbilical compress therapy with Xiaotan Lishui Gel and intraperitoneal chemotherapy with cisplatin in patients with gastric cancer ascites. Methods A total of 78 patients were included and divided randomly into treatment group (39 patients) and control group (38 patients). Patients of both groups received intraperitoneal chemotherapy with cisplatin, and the treatment group received additionally umbilical compress therapy of Xiaotan Lishui Gel. Two weeks were regarded as a course of treatment. All patients were followed up for 180 days. The total effective rate, puncture-free survival, interval time of puncture, median survival time, life quality, improvement of symptoms and safety of the two groups were observed. Results Finally 73 patients completed the observation. The total effective rate was 56.76%(21/37) in the treatment group and 33.33%(12/36) in the control group, with statistical significance (P=0.044). The puncture-free survival and interval time of puncture were 59 d and 62 d, respectively, and 49 d and 54 d in the control group, respectively (P<0.05). There was no difference in median survival time between the two groups. Karnofsky performance status in the treatment group was significantly higher than the control group (P=0.012), and decreased mobility, abdominal pain, abdominal distension, early satiety and urinary frequency in the treatment group were better improved than the control group (P<0.05). Conclusion Combination of umbilical compress therapy with Xiaotan Lishui Gel and intraperitoneal chemotherapy with cisplatin can postpone the ascites increasing speed of patients with gastric cancer ascites, and improve patients’ life quality.

Dao-di Herbs is specificity and locality, and its unique phenotypic features is closely related to the growth and development of medicinal plants. In addition to traditional genetic, epigenetic play an important role in formation of Dao-di herbs. This paper introduces the concept of epigenetic and the role of DNA methylation in the gene expression regulation. We further prospects epigenetic mechanism in study of Dao-di herbs formation from specific phenotype and regional analysis. And study on the relationship of epigenetic and Dao-di herbs will provide a basis for quality assessment and identification of Chinese drugs.

BACKGROUND:Preliminary studies of our research group have confirmed that the proliferation of preosteoclasts and the differentiation and function of osteoclasts could be inhibited when they were cultured in lower oxygen tension even hypoxia (2%O 2 ), but the gene expression of osteoclasts cultured in vitro have not been reported.
OBJECTIVE:To examine the effect of oxygen tension on specific gene expression of osteoclasts in vitro and explore the mechanism of osteoclast differentiation influenced by oxygen tension.
METHODS:The preosteoclasts were induced with 10μg/L macrophage colony stimulating facto and 10μg/L soluble receptor activator of nuclear factor-κB ligand into mature osteoclasts. Then the osteoclasts were cultured in normoxia, tissue oxygen and hypoxia (20%, 7%, 2%O 2 ) respectively. cells were then stained for tartarate-resistant acid phosphatase to assess osteoclastic formation. cells were col ected at 1, 2, 3, 4, 5, 6, 7 days after culture respectively. The soluble receptor activator of nuclear factor-κB ligand, tumor necrosis factor receptor-associated factor 6, tartarate-resistant acid phosphatase, and cathepsin K mRNA expression levels were determined using real-time quantitative PCR.
RESULTS AND CONCLUSION:The number of osteoclasts positive for tartarate-resistant acid phosphatase in the hypoxia was significantly lower than that in the tissue oxygen and normoxia (P<0.05). Under different oxygen tension, the mRNA expression levels of soluble receptor activator of nuclear factor-κB ligand in osteoclasts maintained unchanged. The mRNA expression levels of tumor necrosis factor receptor-associated factor 6 reached the peak at 5 days after culture in tissue oxygen and normoxia (P<0.05). The mRNA expression time of tartarate-resistant acid phosphatase and Cathepsin K were delayed accompanied by decreased oxygen tension, but the maximum were maintained in tissue oxygen. Compared with normoxia and hypoxia, osteoclasts cultured in tissue oxygen are more prone to differentiate and maintain the activity and functions.

Objective To investigate the association between mycoplasma DNA and renal cell carcinoma (RCC). Methods There were 95 samples of archived embedded tissues of RCC. We detected mycoplasma DNA in the tissues by nested polymerase chain reaction (PCR) with mycoplasma universal primer. Results The mycoplasma DNA detection ratio in RCC samples was 81.1%. The samples with moderate and low differentiation had a higher mycoplasma DNA ratio (90.9%) compared with that of high differentiation samples (72.6%) (P

Objective:To observe the effect of breathing andDaoyin exercises on the quality of life in patients with stable chronic obstructive pulmonary disease (COPD) due to deficiency of the lung and kidney (grade II-III).
Methods:A total of 60 eligible cases were randomly allocated into a treatment group (n=30) and a control group (n=30) by random number table. Cases in the control group received routine Western medical treatment, whereas cases in the treatment group conducted breathing andDaoyin exercises in addition to routine Western medical treatment. Patients in both groups were treated for a total of 3 months. Then the observation was made on changes in pulmonary ventilation function, major clinical symptoms, modified Medical Research Council scale (mMRC), distance in 6-minute walk test (6-MWT), COPD assessment test (CAT) and efficacy satisfaction questionnaire for COPD (ESQ-COPD) before and after treatment.
Results:After treatment, the total effective rate was 80.0% in the treatment group, versus 66.7% in the control group, showing a statistical difference (P<0.05). Patients in the treatment group obtained more significant improvement in coughing, sputum production, dyspnea and shortness of breath than those in the control group (P<0.05). Patients in the treatment group obtained more significant elevation in the forced expiratory volume in 1 second percentage of predicted value (FEV1%) and peak expiratory flow rate (PEF%) than those in the control group (P<0.05). Patients in the treatment group obtained lower mMRC score than those in the control group (P<0.05). Patients in the treatment group obtained longer 6-MWT distance than those in the control group (P<0.05). Patients in the treatment group obtained lower CAT score (P<0.01) and higher ESQ-COPD score (P<0.05) than those in the control group.
Conclusion:Breathing andDaoyin exercises combined with routine Western medical treatment are effective for stable COPD (grade II-III) due to deficiency of the lung and kidney and can improve the patients’ quality of life.

Objective To investigate the association between mycoplasma infection and pathogenesis of renal cell carcinoma(RCC). Methods There were 95 samples of archived embedded tissues of RCC and 60 samples of archived embedded normal renal tissues around the tumor for comparison.We detected mycoplasma hyorhinis P40 expression in archived embedded renal tissues by immunohistochemistry(IHC) with mycoplasma hyorhinis monoclonal antibody(MAb) PD4. Results Mycoplasma hyorhinis P40 was present in 64.2%(61/95 cases) of RCC and in 21.7%(13/60 cases) of the paratumor normal renal tissues in controls.The mycoplasma hyorhinis P40 expression ratio in RCC was significantly higher than that in the normal renal tissue,around the tumor(P

Objective To investigate the role of hypoxia inducible factor-1α (HIF-1α) and von Hippel-Lindau (VHL) in murine endochondral ossification. Methods The knockout of HIF-1α or VHL gene in murine osteoblasts was accomplished by conditional knockout technique at 4th, 8th and 12th week, and the differences between wild-type group and knock-out group in endochondral ossification were detected by HE staining, micro-CT scanning, trabecular bone area measurement, calcium content measurement, tetracycline fluorescence labeling, Real-time PCR and Western blotting. Results After knockout of HIF-1α gene in osteoblasts, the expression of vascular endothelial growth factor ( VEGF) reduced, the rate of new bone formation stepped down, the content of calcium became less, and the trabecular bone volume decreased (P <0.05) . After knockout of VHL gene in osteoblasts, the expression of VEGF increased, the rate of new bone formation stepped up, the content of calcium became more, and the trabecular bone volume was promoted (P < 0.001). Conclusion During murine endochondral ossification, VHL/HIF-1α signal pathway promotes angiogenesis through the stimulation of VEGF expression, which subsequently accelerates osteogenesis.

Objective To improve the recognition of meconium ileus and pseudohypoaldosteronism type Ⅰ and to explore the relationship between neonatal meconium ileus and cystic fibrosis.Methods The clinical and follow-up data of a premature infant with meconium ileus and pseudohypoaldosteronism type Ⅰ was analyzed.Relevant literature was reviewed.Results The child was a very low-birth weight premature infant who didn′t pass meconuim within 24 hours of birth and persistent abdominal distention was noted.Laparotomy was performed on day 4.Thick and inspissated meconium was found in the ileum with perforation.The atretic intestine was resected,and a double-barreled enterostomies was performed.On day 30,the child presented hyponatremia,hyperkalemia,high levels of plasma renin and aldosterone and was given 9 g/L salt supplementation.At 6-month age,9 g/L salt supplementation was discontinued.Anastomosis was performed at 8-month age.The child recovered with a good prognosis whose catch-up growth was obtained at 18-month age and didn′t pre-sent manifestations of cystic fibrosis.Conclusions This case could be diagnosed as meconium ileus and pseudohypoaldosteronism type Ⅰ.The relationship between neonatal meconium ileus and cystic fibrosis is different in China and the regions of Caucasian.
