OBJECTIVEThis study aims to investigate the temporal pattern of expression of vascular endothelial growth factor (VEGF) and new bone formation during midpalatal suture expansion osteogenesis for rapid maxillary expansion.

METHODSA total of44 New Zealand white rabbits were randomly assigned to 11 groups, namely, five experimental groups, five control groups, and one control 0 group. A Haas appliance was used for the rapid expansion of the midpalatal suture; rapid expansion was set for 2 weeks and fixed for 4 weeks. The tissue of the maxillary midpalatal suture was harvested on the day of installing rapid expansion (control 0 group), on weeks 1 and 2 for rapid expansion, and on weeks 1, 2, and 4 for fixed (experimental group and control group, respectively). The immunohistochemical method was used to detect distribution and expression of VEGF, and new bone formation was observed with periodic acid-Schiff.

RESULTSHigher VEGF expressions are observed after midpalatal suture distraction osteogenesis. Positive staining for VEGF is mainly noted in the vascular endothelial cells, and the active osteoblasts are at the edge of a newborn trabecular bone. A weak VEGF expression is detected among cells in the control group. The VEGF expression of the experimental group is higher than that of the control group in rapid expansion weeks 1 and 2 and in fixed weeks 1 and 2. The expression of VEGF in the experimental group increases significantly and peaks at fixed week 1, and then gradually decreases. The amount of newly formed bone in the experimental groups is always higher than that in the control group; moreover, it increases significantly and peaks at fixed week 2, and then gradually decreases.

CONCLUSIONThe mechanical strain created by rapid maxillary expansion generates a sequence of VEGF cellular events that lead to increased vascularization and subsequent new bone formation.

Objective To explore the clinical effect of Sophora powder combined with Xianfang-Huoming decoction for ulcerative colitis.Methods A total of 80 UC patients with TCM syndrome of excessive noxious heat were randomly divided into 2 groups (40 patients each group). The Western medicine group(control group) were treated with Mesalazin Enteric-coated tablets, and the Traditional Chinese medicine(observation group) group were treated with Sophora powder combined with Xianfang-Huoming decoction. The tumor necrosis factor-α(TNF-α)and Interleukin-8(IL-8) were detected. The Mayo index scores were conducted, and the curative effect and the recurrence rate were observed.ResultsAfter treatment, the level of TNF-α (66.11 ± 3.72 ng/Lvs. 92.61 ± 4.32 ng/L,t=29.398,P﹤0.01), IL-8 (53.11 ± 2.72 ng/L vs. 69.31 ± 1.32 ng/L,t=33.888,P﹤0.01)in the observation groupwere significantly lower than those in the control group. The Mayo index score (2.07 ± 0.57 vs. 3.30 ± 0.93, t=7.132,P﹤0.01) in the observation group was significantly lower than that in the control group. The total effective rate (92.5% vs. 85.0%,χ2=1.127, P=0.288) in the observation group was not significantly different from that in the control group. The recurrence rate (5.4% vs. 26.5%,χ2=6.005,P=0.013) in the observation group was significantly lower than that in the control group.Conclusions The Sophora powder combined withXianfang-Huoming decoction can treat the UC patients with TCM syndrome of excessive noxious hest, and the its recurrence rate is low.

Based on the subtle discussion of changing rules and its principles of Six Qi movement recorded by one chapter named Liu Wei Zhi Da Lun in the Huang Di Nei Jing Su Wen about rules of Heaven divided by Six, Six Qi and year evolutive phase, Six Qi dominating the time, and guest climatic Qi adding to fixed host Qi, etc, this article explained the changes of influence of Heaven space-time on the human body from the angle of image thinking, focused on the key point of humanity conforming to the nature of the core of Chinese philosophy, and appealed readers to come back to the original thinking of China-image thinking.

Hypotha is the center of energy homeostasis in the organism.The central step of its endocrinology regulation network is that it can receive the leptin signal provided by peripheral adipose tissues,and subsequently modulate the expression of Agouti-related protein(AgRP) and proopiomelanocortin(POMC),maintaining energy homeostasis by regulating energy intake and consumption.Transcription factors FoxO1 and STAT3(signal transducer and activator of transcription 3) are key molecules in leptin-mediated transcriptional regulation of AgRP;they directly participate in the regulation of energy homeostasis.FoxO1 can enhance AgRP expression and activated STAT3 can inhibit AgRP expression.Leptin can modulate AgRP and energy homeostasis through inhibiting FoxO1 activity and activating STAT3.The article reviews the regulatory mechanism of leptin upon AgRP.

Objective:To discuss the effect of optimum program on hypertensive cerebral hemorrhage in acute phase.Methods:380 patients with hypertensive cerebral hemorrhage were selected.They were randomly divided into test group by given two agents(Xuezhongxiao/Zhongfengfangzhiling)+comprehensive rehabilitation(rehabilitation of modern acupuncture)+ medicine-based treatment +microinvasive surgical therapy,and control group by given Chinese medicines(Xuekang /Naoan capsule) + modern rehabilitation+ medicine-based treatment + craniotomy treatment.The curative effects was observed and compared between the two groups.Results:The test group was evidently superior to the constrol one in haematoma clearance rate,nerve functions recovery,extremity rehabilitation and symptoms improvement(P

Objective To investigate the clinic significance of serum carbohydrate antigen ( CA)125 for cirrhosis. Methods 88 patients with type B posthepatitic cirrhosis (male 46,female 24,average age 45?24 years) were divided into three group (A stage35,B stage 28,C stage 25) according to Child-pugh integration. 36 healthy persons as normal controls were studied(male 20,female 16,average age 42?22 years). Serum CA125 was measured by ELISA. We investigated the alteration of serum CA125 with hepatic functional classification. Results The levels of serum CA125 in cirrhosis patients were markedly higher than those in control subjects(P

Objective To observe the effects of IL-4 on the expression of epithelial sodium channel(ENaC) ?-subunit.Methods A549 cells were cultured with IL-4 at the concentration of 0,0.1,1 and 10 ng/ml for 12 h or with 1 ng/ml IL-4 for 3,6,12,24 and 48 h.Then ?-ENaC protein and mRNA expressions were detected by Western blotting and RT-PCR respectively.Results IL-4 decreased the expression of ?-ENaC in A549 cells in a time-and dose-dependent manner,via gene transformation.When A549 cells were cultured with IL-4 at the concentration of 1 ng/ml for 3,6,12,24 and 48 h,the expression of ?-ENaC protein and mRNA were decreased in a time-dependent manner.Statistical analysis showed culture for 6 h had a significant difference compared with other time points(P

Objective To evaluate the value of narrow band imaging(NBI) in the diagnosis of early squamous esophageal cancer and precancerous lesions.Methods Four thousand and fifty-six patients were examined by routine endoscopy,NBI and iodine chromoscopy,one hundred and fourteen lesions in 82 patients were screened.Of all lesions were detected by NBI with magnification and targeted biopsy.The differences among routine endoscopy,NBI and iodine chromoscopy,and the consistency between IPCL and histological findings were assessed.Results Compared to NBI and iodine chromoscopy,especially flat lesions,there was a high missed diagnosis rate in diagnosis of early squamous esophageal cancer and precancerous lesions by routine endoscopy.With NBI and iodine chromoscopy,the incidence rate of lesions was 78.0% and 79.8%,respectively.For iodine staining,85.7% Grade Ⅰ was high grade intraepithelial neoplasia(HGIN),and 66.0% Grade Ⅱ/Ⅲ was low grade intraepithelial neoplasia(LGIN).For NBI,80.4% Grade Ⅰ was HGIN,but there was no specificity in diagnosis LGIN.In appearance of IPCL,92.9% Type Ⅳ/Ⅴ was HGIN,89.4% Type Ⅱ/Ⅲ was LGIN,and it has a relatively better consistency in IPCL with histological findings.Conclusion There is a high detection rate in diagnosis of early squamous esophageal cancer and precancerous lesions by Lugoul's iodine staining and NBI endoscopy.It's probably that IPCL patterns by NBI with magnification can provide scientific basis for both the endoscopic theraphy of early esophageal cancer and the omen of postoperative recurrence.

Objective To assess the value and complications of restaging laparotomy in women with presumed early ovarian cancer who have undergone inadequate initial staging procedures. Methods Between 1986 and 1996, 42 patients underwent restaging laparotomy in Cancer Hospital, Peking Union Medical College after receiving inadequate initial surgical procedure for presumed early ovarian cancer. Presumed stages from initial surgery include stage Ⅰa in 28 cases; Ⅰb in 1 case; Ⅰc in 12 cases; Ⅱa in 1 case. Histological distributions were as follows: epithelial cancer in 26 cases; malignant germ cell tumor in 9 cases; granulose cell tumor in 7 cases. Results Twelve patients (28.6%) had disease upstaged and eight (19.0%) had stage Ⅲ disease confirmed by restaging laparotomy. Positive findings at restaging laparotomy were mainly in omentum (16.7%) and pericolic gutters (33.3%). Peritoneal cytology was positive in 25.0 percent of patients. Three and five year survival rates for 30 patients with negative findings were 96.7% and 86.7%, respectively. Complications of restaging laparotomy included hemorrhage blood loss (50～ 1 100 ml, average 280 ml) and lymphocyst (7.1%). Conclusions Patients with presumed early ovarian cancer who had undergone inadequate staging procedures should undergo restaging laparotomy. Patients with negative findings have an excellent prognosis. Complications of restaging laparotomy were minor.
