Objective To investigate the changes of enteric nervous system in gastrointestinal motility disorder in rats with severe acute pancreatitis (SAP) as well as the influence of Chaishao Chengqi Decoction on neuronal nitric oxide synthase neuron (nNOS) neuron expression in myenteric plexus of rat intestinal tract. Methods SD rats were randomly divided into 3 groups (10 for each): sham operation group, model group and Chaishao Chengqi Decoction (CSCQD) group. SAP model was established in taurocholate into the junction of the common bile duct and pancreatic duct. Model group was administered with normal saline and CSCQD group was administered with Chaishao Chengqi Decoction. The gastrointestinal transmission time was observed. Pathological changes of the pancreas were examined with HE staining under light microscope. The neuronal nitric oxide synthase neurons in the small intestines and colonic myenteric plexus were detected by the dual immunofluorescent staining. Results Compared with that in model group, transmission index was increased in CSCQD group (P<0.05). The pathological lesion of the pancreas in CSCQD group was significantly lessened (P<0.05). The percentage of NOS-immunoreactive neurons was significantly decreased (P<0.05). Conclusion By reversing the plasticity of NOS-immunoreactive neurons, Chaishao Chengqi Decoction improves the gastrointestinal motility in rats with SAP and reduces the pathological damages of the pancreas.

Objective To observe the clinical effect and comfortable degree of the mode of super hair removal. Methods The mode of super hair removal was used to depilate the hair nearby the hair line, cheeks, upper lip, beard, ventrum, areola of breast, axillary cavity, extremities, bikini area and so on. The total number of sites was 1 000. Some sites that were especially susceptible to pain, for example, upper lip and buccal region, were smeared with compound lidocaine cream for 1 hour at least before treatment. Results Hairs in the areas of extremities, ventrum, back and axillary cavity generally needed 4 to 5 times to eradicate, and the patients had no evident discomfortableness; hairs near to the upper lip and lower mandible generally needed 5 to 7 times to reach the effect which the patient was content, and anesthetics was indispensable, or the patients would present discomfortableness. Conclusions The mode of super hair removal is more effective, quicker and more comfortable in comparison with conventional methods. Therefore, it deserves to be spread.

Objective To explore more satisfactory results in correcting the aesthetically short nose combined with low and blunt nasal tip by using autologous cartilage grafts.Methods External rhinoplasty approach was preferred.Nasal septal cartilage and auricular cartilage or rib cartilage of patients were adopted,as necessary,various shapes of grafts were carved,such as septal extention graft,columella strut and shift graft.Then we used these autologous cartilage grafts with suture and removal techniques to correct the aesthetically short nose combined with low and blunt nasal tip.The length of the nose (n-prn) and the projection of nasal tip (sn-prn) were measured before and after the operation.Paired t-test was adopted to evaluate the results.Results Thirty-one patients accepted the nasal tip rhinoplasty with autologous cartilage whose nasal tip was over rotation,blunt and low.All the patients were followed up for 3 months.Thirty patients satisfied with the results,accounting for 96.7 ％ of the total.()ne (3.3 ％) patient dissatisfied with the result because of postoperative asymmetry nostrils.Nose length before and after surgery was significantly different (P＜0.05).Nasal tip projection before and after surgery was also significantly improved (P＜0.05).Conclusions It is an effective method to use autologous cartilage graft for correcting the aesthetically short nose combined with low and blunt na sal tip,with low complications.

OBJECTIVELooking for an objective biomedical index to distinguish types and phases of hemangioma in order to provide an objective basis for selecting clinical treatment to hemangioma.

METHODSELISA (enzyme-linked immunosorbent assay) was used to determine serum VEGF concentration of 15 patients with proliferative hemangioma, 6 with involuted hemangioma, 6 with vascular malformation and 8 infants of the control group.

RESULTSThe serum VEGF concentrations of 15 proliferative hemangioma patients were significantly higher than those of involuted hemangioma patients, vascular malformation patients and control group infants. The serum VEGF concentrations of involuted hemangioma patients were a little bit higher than those of vascular malformation patients and control group infants, but without statistic significance.

CONCLUSIONSELISA could easily and accurately determine the serum VEGF concentration of different types and different phases of hemangioma. The determination of serum VEGF concentration could provide guidance for selecting a protocol of systemic corticosteroid treatment for proliferative hemangioma. Combined with gene expression and distribution of VEGF and its receptors and some other cytokines, the determination of serum VEGF concentration could help elucidate the mechanism of proliferative hemangioma.

Objective To understand the frequency distribution of CYP2C9 and VKORC1 gene single nucleotide polymor-phisms in Yunnan Han population.Methods CYP2C9(430C> T,1075A>C and 1080C> G)locus and VKORC1(-1639G> A and 1173C> T)locus gene polymorphisms in 202 samples were detected by adopting electrochemical gene sensor method,and the allele frequencies and genotype frequencies were performed the statistics and the gene polymorphism in relevant populations was an-alyzed.Results Among 202 samples,202 cases(100.0%)were genotype C/C at CYP2C9 * 2 locus,C allele frequency was 100.0%;185 cases(91.6%)were genotype A/A at CYP2C9*3 locus,15 cases(7.4%)were A/C genotype,2 cases(1.0%)were C/C genotype,A allele frequency was 95.3%,C allele frequency was 4.7%;CYP2C9*5 locus genotype C/C was in 202 cases (100.0%),C allele frequency was 100%;VKORC1 -1639G > A locus genotype A/A was in 145 cases(71.8%),57 cases (28.2%)were G/A genotype,A allele frequency was 85.9%,G was 14.1%;1173C> T locus genotype T/T was in 145 cases (71.8%),C/T gene type in 57 cases(28.2%),T allele frequency was 85.9%,and C was 14.1%.Conclusion The distribution of CYP2C9 gene in Yunnan Han population is similar to that in other regions of our country.The VKORC1 gene is different from the foreign population,Chinese Han nationality and partial minority nationalities.
