Objective To evaluate the effects of Wuqinxi bear play on TCM symptoms and health status in patients with chronic atrophic gastritis of Qi deficiency of spleen and stomach.Methods A total of 60 patients with chronic atrophic gastritis admitted to the Department of Gastroenterology in our hospital were selected.Using random number table method,the patients were divided into the intervention group and the control group with 30 cases in each group.The intervention group adopted bear play for exercise,and the control group was treated with routine treatment and nursing.The scores of TCM symptoms and SF-36,and reports of endoscope were compared between two groups.Results The scores of TCM symptoms in the intervention group were decreased after 2 and 4 weeks' of intervention.The score of each factor in SF-36 was increased and results of endoscope report were improved after 12 weeks' intervention.The differences were statistically significant(P＜0.05).Conclusion Bear play can effectively alleviate symptoms of chronic atrophic gastritis of Qi deficiency of spleen and stomach,and improve patents' quality of life.

Vascular perfusion distribution in fibroids contrast-enhanced ultrasound images provides useful pathological and physiological information, because the extraction of the vascular perfusion area can be helpful to quantitative evaluation of uterine fibroids blood supply. The pixel gray scale in vascular perfusion area of fibroids contrast-enhanced ultrasound image sequences is different from that in other regions, and, based on this, we proposed a method of extracting vascular perfusion area of fibroids. Firstly, we denoised the image sequence, and then we used Brox optical flow method to estimate motion of two adjacent frames, based on the results of the displacement field for motion correction. Finally, we extracted vascular perfusion region from the surrounding background based on the differences in gray scale for the magnitude of the rich blood supply area and lack of blood supply area in ultrasound images sequence. The experimental results showed that the algorithm could accurately extract the vascular perfusion area, reach the precision of identification of clinical perfusion area, and only small amount of calculation was needed and the process was fairly simple.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).

METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.

RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.

CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.

The effect of cholesterol ester transfer protein(CETP) on SR-B1 mRNA expression in mouse liver was investigated.The results demonstrated that CETP transgenic mice showed lower serum total cholesterol and high density lipoprotein-cholesterol levels but higher total cholesterol and cholesterol ester content in liver when compared with wild type mice(P＜0.05).The expression of SR-B1 mRNA in liver of CETP transgenic mice was significantly lower as compared with the control group(P＜0.05).

Objective To investigate the effects of postoperative adjuvant chemotherapy (CT) and chemoradiotherapy (CRT) or radiotherapy(RT) for Ⅰ b-Ⅱ a cervical cancer with risk factors.Methods From March 1995 to June 2010,there were 137 patients underwent radical hysterectomy and systematic pelvic lymphadenectomy for stage Ⅰ b-Ⅱ a cervical cancer admitted at Peking University First Hospital.These patients had risk factors,intermediate risk factors including bulky tumor (＞4 cm),lymph vascular space invasion,deep stromal invasion; high risk factors including positive surgical margin,parametrial invasion,lymph node involvement.Of the all patients,79 cases of them were treated with CT,58 of them were treated with RT or CRT.The 5-year survival and prognosis factors were analyzed retrospectively,the prognosis was compared between two adjuvant therapy groups.Results The univariate analysis shown that types of pathology,different grade of risk factors,stroma invasion and lymph node involvement were prognostic factors of 5-year overall survival Patients with squamous cell carcinoma,intermediate risk factors,no parametrial invasion,and no lymph node involvement had better prognosis (P ＜ 0.05).Whether patients with high-risk factors or intermediate-risk factors,the 5-year overall survival and 3-year disease-free survival had no difference between CT and RCT or RT groups respectively.Cox regression multivariate analysis of survival indicated that clinical stages,types of histology,different grade of risk factors were independent prognostic indicator.Patients with early stage,squamous cell carcinoma,intermediate risk factors had better prognosis.Univariate and multivariate analysis indicated that different postoperative adjuvant therapies had no effects on the prognosis.The 5-year overall survival was 88.6％ in patients treated with CT,and 89.7％ in patients treated with RT or CRT (P =0.455).Conclusion There are equivalent therapeutic results between CT and RT or CRT for patients with risk factors after radical surgery,CT may be as one choice of postoperative adjuvant therapy for stage Ⅰ b-Ⅱ a cervical carcinoma with risk factors.

Objective To observe he effects of new Tangshenkang on α-SMA and E-cadherin of human renal tubular epithelial cell HK-2 in high concentrations of glucose; To explore the mechanism of new Tangshenkang on the prevention and treatment of diabetic renal fibrosis. Methods The HK-2 cells were cultured and divided into control group, high glucose group, animal serum control group, new Tangshenkang low-, medium-, and high-dosage group. After medicine intervention, cell proliferation was tested by MTT assay, and contents of α-SMA and E-cadherin were observed by ELISA assay. Results Compared with control group, α-SMA of HK-2 cultured with high glucose was much notable, but the content of E-cadherin significantly decreased, with statistical significance (P<0.05). The content of α-SMA of HK-2 cultured with new Tangshenkang decreased, and the content of E-cadherin increased; cell proliferation was markedly inhibited in culture medium supernatant of HK-2 cells cultured with high glucose plus new Tangshenkang compared with only high glucose, with statistical significance. Conclusion New Tangshenkang can inhibit cell proliferation and epithelial-myofibroblast transdifferentiation of HK-2 cell induced by high glucose, and prevent the development of diabetic renal fibrosis to a certain extent.
