Buluo Buguan Decoction originates from ZHANG Xi-chun's book Yi Xue Zhong Zhong Can Xi Lu, with the functions of astringent, removing blood stasis, and vein relaxing. The original major functions of this decoction are to treat chronic hemoptysis and hematemesis. In long-term clinical practice, Professor SHAO found that the modified decoction showed significant positive outcome in the treatment of hematuria, nocturnal emission, spontaneous sweating, night sweats, and allergic purpura nephritis, with good efficacy.

OBJECTIVETo investigate the morphology of the soft palate in normal individuals with digital radiography, when they pronounced the high vowel of "i", and to provide the references for therapy of the cleft palate.

METHODSIn this study, the sample comprised 27 normal subjects. With the digital cephalometry, the morphology of the soft palate when pronouncing the high vowel of "i" was observed. And the dimensional difference of the soft palate when pronouncing between different gender was studied.

RESULTSWhen pronouncing the high vowel of "i", the morphology of the soft palate was like the shape of the knee. And it could be divided into two parts: horizontal and vertical. The length of the vertical part in male group was (24.92 +/- 2.03) mm, the length of the vertical part in the female group was (20.66 +/- 2.77) mm. The length of the vertical part was different between male and female group (P < 0.001).

CONCLUSIONThe morphology of the palate when pronouncing the high vowel of "i" is similar. And the velar length of the vertical part of the male is longer than the female.

OBJECTIVETo compare the synthetic ability of osteoblasts on the surface of different nano-granule titanium films and investigate the correlation between nanophase titanium films and cellular biocompatibility.

METHODSFour different nano-granule titanium films were produced by direct current magnetron sputtering, at ambient, 100 degrees C, 250 degrees C, 380 degrees C substrate temperature, respectively. Rat osteoblasts were seeded on the surface of four treated groups of titanium film samples and non-treated Ti sample(control group). The production of osteocalcin (OC) in all five groups were detected by using double antibody sandwich enzyme-linked immunosorbent assay.

RESULTSThe production of OC increased gradually from day 7 to day 14 in all groups. In the control group, it showed significant differences with other five groups on day 7. On day 14, the production of OC in 100 degrees C group was the highest, and it showed significant differences with 380 degrees C, control group and blank group. In 250 degrees C group, the production of OC also showed significant differences with 380 degrees C, control group and blank group (P < 0.05).

CONCLUSIONTitanium with nano-modified surface had good biocompatibility and different nano-granule titanium films could affect the synthesis of osteoblasts.

PURPOSE: CO₂ leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasis after laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis between B-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). MATERIALS AND METHODS: Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC. Clinical efficacy was assessed from the objective remission rate (ORR), the Karnofsky Performance Status (KPS) score, and overall survival. The incidence of port-site metastasis was compared between the two groups. RESULTS: Patients in the B-ultrasound (n=32) and laparoscopy (n=30) groups were comparable in terms of age, sex, primary disease type, volume of ascites, and free cancer cell (FCC)-positive ascites. After HIPPC, there were no significant differences between the B-ultrasound and laparoscopy groups in the KPS score change, ORR, and median survival time. The incidence of port-site metastasis after HIPPC was not significantly different between the B-ultrasound (3 of 32, 9.36%) and laparoscopy (3 of 30, 10%) groups, but significantly different among pancreatic, gastric, ovarian, and colorectal cancer (33.33, 15.79, 10.00, and 0.00%, p<0.001). CONCLUSION: The chimney effect may not be the key reason for port-site metastasis after laparoscopy. Other factors may play a role, including the local microenvironment at the trocar site and the delivery of viable FCCs (from the tumor or malignant ascites) to the trauma site during laparoscopic surgery.

OBJECTIVETo observe the impact of heat-sensitive moxibustion on lung function in chronic persistent bronchial asthma and analyze its effect on the improvement of life quality as well as compare its efficacy with Seretide inhaler.

METHODSFifty-seven cases were divided into a heat-sensitive moxibustion group (28 cases) and a Seretide group (29 cases) according to the random number table. In heat-sensitive moxibustion group, the therapy of heat-sensitive moxibustion was applied to the regions at the level of Feishu (BL 13) and Geshu (BL 17), or to the heat-sensitized points in the region 6 cun lateral from the 1st and 2nd intercostal spaces in the chest. The treatment was given continuously for 8 days, once per day, 12 treatments should be ensured in the later 22 days of the 1st month. In the later two months since then, 15 treatments should be ensured each month (< or = 1 treatment each day). In Seretide group, Seritide manufactured in GlaxoSmithKLine was used, one inhalation each time, twice per day. The cases in both groups were received treatment for 3 months. The changes in lung function such as forced expiratory volume one second (FEV1), TCM symptoms score, Asthma Control Test (ACT) and St George's Respiratory Questionnaire (SGRQ) were assessed and compared between two groups and within group separately.

RESULTSLung function as FEV1 was improved in either group (P < 0.05, P < 0.01). The terminal improvement effects on symptoms of Chinese medicine, life quality and others were same between two groups (all P > 0.05). But the improvements in general situation, chills, fever and sweating in heat-sensitive moxibustion group were superior to those in Seretide group (both P < 0.05). Concerning to the improvement in respiratory symptoms, the effect of Seretide was better than that of heat-sensitive moxibustion (P < 0.05).

CONCLUSIONHeat-sensitive moxibustion improves lung function, relieves clinical symptoms and benefits life quality for patients with chronic persistent bronchial asthma. It's efficacy on the disease is equal to the internationally-recognized effect of Seretide.

Objective:To explore the effect of different effective parts of Taohe Chengqitang on the synthesis and degradation of extracellular matrix in human kideny-2（HK-2） cells induced by transforming growth factor-β₁（TGF-β₁）. Method:Petroleum ether extract, ethyl acetate extract, n-butanol extract, raffinate and polysaccharide extract, mirabilite extract were extracted with 70% ethanol by systematic solvent method. The HK-2 cell fibrosis model induced by TGF-β₁ was built to intervene the cells in different parts of Taohe Chengqitang with different concentrations (0, 50, 100, 200, 400, 800 mg·L^-1). Enzyme-linked immunosorbent assay（ELISA）kit assay was used to detect collagen（Col）-Ⅰα1 and fibronectin （FN）in supernatant to screen out the main active parts. Cell counting kit-8 （CCK-8）method was used to determine the best concentration of intervention site of bioactive components. Western blot analysis was used to detect the expression levels of Col-Ⅰ, Col-Ⅲ, matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase inhibitor2 (TIMP2), and connective tissue growth factor (CTGF). Immunofluorescence assay was used to detect the expression of α-smooth muscle actin（α-SMA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） analysis was used to detect the mRNA expression of plasminogen activator inhibitor-1（PAI-1）. Result:ELISA kit assay demonstrated that compared with the model group, ethyl acetate extract, n-butanol extract and chloroform extract significantly reduced the Col-Ⅰα1 and FN content at the concentrations of 200 and 400 mg·L^-1 (P<0.05, P<0.01). CCK-8 assay showed that the cells viability was significantly inhibited with drug intervention at the concentrations of 400 and 800 mg·L^-1 (P<0.01). Western blot demonstrated that compared with the model group, ethyl acetate extract, n-butanol extract and chloroform extract decreased the expression levels of Col-Ⅰ, Col-Ⅲ, TIMP2 and CTGF in HK-2 cells induced by TGF-β₁, and increased the expression of MMP-2 (P<0.05), with more significant effect in n-butanol extract (P<0.01). The results of immunofluorescence showed that ethyl acetate extract, n-butanol extract and chloroform extract could inhibit the expression of α-SMA (P<0.05), with more significant effect in n-butanol extract (P<0.01). The results of Real-time PCR showed that ethyl acetate extract and chloroform extract inhibited mRNA expression of PAI-1 (P<0.05), with more significant effect in n-butanol extract (P<0.01). Conclusion:The extracts of ethyl acetate, n-butanol and chloroform are the active parts of Taohe Chengqitang with the anti-renal fibrosis effect, with n-butanol extract as the most active part. The mechanism on anti-renal fibrosis may be related to its regulation of extracellular matrix (ECM) synthesis and degradation.
