Methods 400 patients with condyloma accuminatum were divided into the control group and the experimental group with 200 patients in each group, traditional oppression for hemostasis and bubble retention hemostasis were used in CO2 laser treatment against condyloma acuminatum respectively.The effect of each group was compared with χ2 and t test. Results The relapse rate and hemorrhage rate in the experimetnal group was lower than those of the control group. Conclusions With indwelling bubble technique after infiltration anesthesia of local skin in the treatment of condyloma accuminatum by CO2 laser, the operator can work under clear vision and the op-eration quality can be increased.

Alzheimer's disease (AD) is the most common cause of cognitive impairment in older people. With the aging of society is more and more serious, AD caused great burden to patients and society. A β is a classical biomarker of AD, which has been widely used in clinical diagnosis of AD patients. Compared with positron emission tomography (PET) and single photon emission computed tomography (SPECT), near infrared fluorescence imaging has many advantages including highly sensitive, non-invasive, safety and inexpensive. Therefore, many research groups have focused on developing the molecular probes of near-infrared fluorescence (NIRF) imaging. In this article, we will review the progress of the probes of NIRF.

Objective To establish a method for the determination of content in Sinomenine Hydrochloride external applied powder.

Objective To evaluate the relationships of the expression of orexin A in hypothalamus with hyperleptinemia, hyperinsulinism, and hyperlipidemia in alimentary obesity rats.Methods The alimentary obesity rat model was induced by high-fat diet in Wistar rats. The levels of leptin, insulin, C-peptide, total cholesterol (TC) and triglyeride (TG) were detected by luminescent immunoassay and biochemistry enzymic method. The gene expression of orexin A in rat hypothalamus was detected by real-time PCR. The correlation between orexin A and leptin was analyzed. Results After 8 weeks of high-fat diet feeding, the body weight, Lee's index, blood glucose, TG and TC significantly increased in obesity rat group (P＜0. 01). The levels of serum leptin, insulin and C-peptide were significantly higher in obesity rats than in controls [( 1.74±0. 36)μg/Lvs. (1.27±0.11) μg/L, (35±5) MIU/L vs. (23±4) MIU/L, (0.21±0.04) μg/L vs.(0. 14±0. 03) μg/L respectively, P＜0.01]. However, the level of orexin A mRNA was lower in obesity rats than in controls (6.8±2.3 vs. 14.5±3.6, t=-8.06, P＜0.01). The correlation coefficient (r) of orexin A mRNA with serum leptin, insulin, and C-peptide in alimentary obesity rat were -0. 726 (P＜0.01), -0. 506 (P＜0.01) and -0. 664 (P＜0.01), respectively. Conclusions High-fat diet can induce leptin-resistance and alimentary obesity in Wistar rat. The down-regulation of orexin A in rat hypothalamus would be correlated closely to the leptin and insulin resistance in alimentary obesity.

AIM To study the inhibitory effect of the cytotoxin (CTX) from guangxi cobra venom on human nasopharyngeal cancer cell (CNE) and other tumons cells. METHODS The cytotoxin was isolated and purified from Guangxi cobra venom by successive chromatography on Sephadex G-50 and CM Sepharose CL-6B columns. Its cytotoxic effects and does-effect relationship on human tumors cell lines were examined by MTT assay. RESULTS The inhibitory effects of CTX CM-5 on CNE, human ovarian carcinoma cell (Ho8990), uterus cervical carcinoma cell (HELA) and lymphoma (YAC) cell lines showed a definite does-effect relationship. The IC 50 (48 h in cubation) was 1.84, 2.59, 1.84 and 0.75 mg?L -1 respctively. The inhibitory effects of CTX CM-5 on CNE increased with time. The IC 50 (3 h and 24 h cubation) was 4.78 and 1.04 mg?L -1 respctively. CONCLUSION CTX from Guangxi cobra venom exhibites strong suppressive effect on cultured tumor cells line in vitro.

Orexin is a new neuropeptide related to diet intake and regulation of endocrine and metabolic functions. Rat model with insulin resistance (IR) was induced by high fructose diet and the extent of IR was assayed by hyperinsulinemic euglycemic clamp technique. The results showed that high fructose diet might induce IR and results in disturbance between orexin and leptin. Blood glucose, serum insulin, lipid metabolism and leptin may participate in the regulation of orexin.

OBJECTIVEThis study aims to evaluate the effect of customized titanium mesh, which was designed by mirror imaging and rapid prototyping technique, with Medpor applied for orbital fracture with enophthalmos.

METHODSOrbital axial, coronal, and sagittal CT scan, and three-dimension CT examination were performed routinely in. 18 cases of orbital fracture with enophthalmos preoperatively. Based on the CT data, prosthesis model was designed by reverse engineering and rapid prototyping technique. The customized titanium mesh and Medpor were applied for orbital reconstruction and enophthalmos correction. Orbital reduction and globe projection were evaluated by postoperative CT scan and clinical follow-up visits.

RESULTSCT scans revealed that the customized titanium mesh with Medpor had great accuracy to reconstruct the orbital fracture and correct the enophthalmos in all patients without serious complications. The eye and facial appearance and function recovered significantly. No serious complication occurred in the operation and after operation.

CONCLUSIONThe customized titanium mesh, based on mirror imaging and rapid prototyping technique, can accurately reconstruct the orbital fractures with enophthalmos. The application of Medpor can effectively correct enophthalmos and eyeball mobility malformation.
