Objective To observe and evaluate clinical feasibility and efficacy of endoscopic metal stenting and combined radiotherapy in treatment of medium and late stages of esophageal carcinoma. Methods 34 cases of medium and late stages of esophageal carcin oma were treated with endoscopic stent implantation and in combination with sten t and radiotherapy. Evaluation of CES stainless metal stent on rad iation effect, clinical symptom alleviation and complication rates and survival rates in both groups was made. Results 1) CES stainless stent had no effect on radiation dosage distribution; 2) Dysphagia was markedly alleviated in both groups and no differe nce in complication rates was observed between two groups; 3) The survival rates of 6,9,12 months in patients treated with combined therapies were significantly higher than those in simple stent implantation patients. Conclusions Endoscopic metal stenting in combination with radiothe rapy was a feasible and practical management in treating medium and late stages of esophageal carcinoma, which was superior to simple metal stent implantation.

Research on novel pullulanase has major significance on the domestic industrialization of pullulanase and the breakdown of foreign monopoly. A thermophilic bacteria LM 18-11 producing thermostable pullulanase was isolated from Lunma hot springs of Yunnan province. It was identified as Anoxybacillus sp. by 16S rDNA phylogenetic analysis. Full-length pullulanase gene was cloned from Anoxybacillus sp. LM18-11. The optimum temperature of the pullulanase was between 55 and 60 degrees C with a half-life as long as 48 h at 60 degrees C; and its optimum pH was between 5.6 and 6.4. V(max) and K(m) of the pullulanase was measured as 750 U/mg and 1.47 mg/mL, which is the highest specific activity reported so far. The pullulanase crystals structure showed a typical alpha-amylase family structure. The N-terminal has a special substrate binding domain. Activity and substrate binding were decreased when the domain was deleted, the V(max) and K(m) were 324 U/mg and 1.95 mg/mL, respectively. The pullulanase was highly heterologous expressed in Bacillus subtilis by P43 promoter. The extracellular enzyme activity was 42 U/mL, which increased more than 40 times compared to the initial strain. This pullulanase has good application prospects.

Objective To assess the awareness of nutrition issues among patients with type 2 diabetes mellitus (T2DM) and to find effective nutrition education models. Methods According to cluster random sampling method,256 T2DM patients from 2 hospitals in Zhengzhou City were enrolled and randomly assigned to the study or control group. The participants in the study group received traditional nutrition education and real object-based diabetic diet guidance, and those in the control group received traditional nutrition education only. Awareness about nutrition and blood glucose levels were compared between the two groups by using independent t test and Chi-square test Results After the intervention, the study group showed significantly higher nutrition scores ( 86. 5 ± 3.8 vs 71.5 ± 4. 6, P < 0. 05 ) and lower 2 h postprandial glucose level ( ( 9. 15 ± 1.06 ) mmol/L vs ( 11.32 ± 0. 84) mmol/L, P < 0. 05 ). Conclusion Real object-based diabetic diet teaching could foster the awareness in nutrition and decrease postprandial blood glucose level in T2DM patients.

Objective To study the differences in the inclination of lower incisors among the female patients with beautiful profiles in different vertical skeletal types so as to provide the clinical treatment design for a certain guiding. Methods 137 cephalometric films of female patients with beautiful profiles were selected and divided into three groups based on the vertical facial types(∠SNMP):small degree(n = 31),average degree(n = 89) and larger degree groups(n=17). The angles of∠L1/MP and∠L1/A-Pog were measured and treated with covari-ance analysis for detecting the differences between the groups. Results The index of L1-MP(°)was the smallest in the larger degree group,the largest in the small degree group and average in the average group,with significant differences between the three groups(F = 17.38,P < 0.001). There was no significant differences in ∠L1/A-Pog (°)(F=2.61,P>0.05). Conclusion Lower incisors have compensatory inclined lingually in the group of higher mandible angle,but labially in the group of lower mandible angle.

Collateral disease theory has been applied to investigate the pathogenesis of chronic dermal ulcer in traditional Chinese medicine. It is suggested that deficiency of vital qi is the pathological basis of chronic dermal ulcer with collaterals stagnation as the major pathological factor, and collaterals impairment by toxin evil is the main pathological change. The important principle in treatment of chronic dermal ulcer is established as strengthening the body resistance, dredging collaterals and removing toxins, and this enriched the theory of wound healing in traditional Chinese medicine, and has practical value.

To establish a UPLC-MS/MS method for the simultaneous determination of geniposide, genipin 1-O-beta-D-gentiobioside and geniposidic acid in rat brains and study the brain pharmacokinetics of the three iridoid glycosides in stroke rat after the oral administration of Xingnaojing. In this experiment, brain samples were precipitated with protein for twice. Acquity BEH C18 column was adopted, with acetonitrile-0.1% formic acid-water as the mobile phase for gradient elution. ESI source was adopted for mass spectra; multiple reaction monitoring (MRM) was conducted to detect negative ions. The time for sample analysis was 3.5 min. the results showed good linear relations among the three iridoid glycosides, with the extraction recovery between 99.6% and 114.3%, good intra- and inter-day precisions and accuracies and stability in line with the requirements. The t1/2 and MRT in the three components were similar in brains of stroke rats. Geniposide and genipin 1-O-beta-D-gentiobioside showed double peaks; where as geniposidic acid showed a single peak. In conclusion, the method is so specific, sensitive, accurate and reliable that it can be used to study the brain pharmacokinetics of Xingnaojing oral preparation.

Objective: To investigate the anatomic basis of vascularized ulnar nerve graft by the pedicle of the superior collateral ulnar artery (SCUA).Methods: Twenty-two fresh cadaver upper extremities injected intra-arterially with latex were dissected to study the extrinsic blood supply of the ulnar nerve.Other 6 fresh upper extremities were used to analyze the blood supply range of SCUA inside the ulnar nerve by microangiographic and histological methods,Results: The ulnar nerve was supplied by a branch of the lateral thoracic artery or directly by the axillary artery in the axillary section, by branches of SCUA in the upper arm. And by branches from the anastomosis of the collateral arteries and the posterior branch of the recurrent ulnar artery in the elbow. SCUA could supply the whole ulnar nerve from the axilla to the wrist. Conclusions: The ulnar nerve can be used as a vascularized nerve graft by the pedicle of SCUA in treatment of brachial plexus roots avulsion by C7 transfer from healthy side.

In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.
