Cultivation of wild Fritillaria glabra can be easily achieved without extra energy consumption simply by shading the seedbed from light to lower 2.7 to 3℃ C of bed temperature with concomitant increase of relative humidity. By so doing, ciltivation can be carried out on ground 1200m lower sea level than its native habitat. Successfal cultivation of F.glabra in Feng county, Shaxi Province, resulted in excellent thigh yield.

Objective To investigate the correlation between the serum thyroid-stimulating hormone levels and the outcomes in patients with acute ischemic stroke.Methods Patients with acute ischemic stroke were enrolled prospectively.The general clinical data,vascular risk factors,and biochemical indexes including thyroid hormones were collected.The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the severity of baseline neurologic deficit.The modified Rankin Scale (mRS) was used to evaluate the neurological outcomes at day 90 after onset.The mRS 0-2 was defined as good outcome.Multivariate logistic regression analysis was used to identify the independent influencing factors of the poor outcomes in patients with acute ischemic stroke.Results A total of 140 patients with acute ischemic stroke were enrolled,including 95 men (67.86％) and 45 women (32.14％),aged 35-94 years old.Thirteen patients (9.29％)had subclinical hyperthyroidism and 17 (12.14％) had subclinical hypothyroidism.Ninety-eight patients (70.00％) had good outcome and 42 (30.00％) had poor outcome.The proportions of male (x2 =4.717,P =0.047) and small arterial occlusive stroke (x2 =5.564,P =0.018),as well as uric acid (t =2.602,P =0.010),FT3 (t =2.406,P=0.017),and TSH (t =2.302,P =0.023) in the good outcome group were significantly higher than those in the poor group (P =0.001);age (t =-3.489,P=0.001),fasting blood glucose (Z =-2.178,P =0.031),and baseline NIHSS score (t =-8.009,P ＜ 0.001) were significantly lower than those of poor outcome group.The proportion of patients with TSH in the first quartile (＜0.805 mU/L) in the good outcome group was significantly lower than that in the poor outcome group (17.35％ vs.42.86％;x2 =10.204,P =0.003,and that in the fourth quartile (＞ 2.476 mU/L) was significantly higher than the poor outcome group (30.61％ vs.11.90％;x2=5.488,P=0.002).Multivariate logistic regression analysis showed that after adjusting various confounding factors,the higher baseline NIHSS score was an independent risk factor for poor outcome at day 90 after onset (odds ratio,1.690,95％ confilence interval 1.317-2.168;P＜ 0.001),while the higher baseline TSH level was associated with good outcome (odds ratio,0.520,95％ confidence interval 0.408-0.867;P=0.007).Conclusions The higher serum TSH level was independently associated with good neurological outcome at day 90 after onset in patients with acute ischemic stroke.

Objective To summarize experience in pectoralis major myocutaneous (PMMC) flap reconstruction for patients undergoing head and neck surgeries. Methods We conducted a retrospective study to analyse the clinical data of 20 patients who had PMMC flap reconstruction in a head and neck surgery from March 2011 to June 2016. All patients were male,with the average age of 54 years(ranging from 27 to 71 years). The PMMC flaps of all patients survived after the surgery. Only one patient developed pharyngocutaneous fistula ,and was recovered after treatment with incision dressing. Among follow?ups for 2 to 24 months,all patients got well recovered,the swallowing and communication functions normal communication and the appearance a satisfactory. good looking. Conclusion PMMC renders effective flathe flap reconstruction with broad clinical application value is an optimal choice for patients underwent head and neck surgery with muscle or skin defect,especially for those who had postoperative radiotherapy because of its rich blood supply and it has a lot of affluent tissues,fmore flexibility inle application and higher survival rate. So it is highly applicable,especially for grass?roots hospitals.

Subclinical thyroid dysfunction including subclinical hypothyroidism and subclinical hyperthyroidism, subclinical hypothyroidism is more common in the general population. Subclinical thyroid dysfunction may increase the incidence of risk factors of stroke, like hypertension, diabetes melitus, dyslipidemia, atherosclerosis, atrial fibrilation, homocysteinemia and so on. Subclinical thyroid dysfunction may be associated w ith the outcomes in patients after acute ischemic stroke.

Objective To investigate whether catestatin (bovine chromogranin A 344-364) can inhibit the biofilm formation of Candida albicans and examine its relationship with the expression of adhesion gene HWP1.Methods Clinical strains and standard strain ATCC 10231 of C.albicans were studied.XTT [2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide] method was used to assess the ability of C.albicans biofilm formation.Antifungal activity against planktonic Candida ceils was evaluated in terms of minimum inhibitory concentrations (MICs) according to the description in CLSI-M27-A3.XTT assay and colony count were used to assess the effect of catestatin on inhibiting C.albicans biofilm formation.The lowest concentration showing 50 ％ inhibition on biofilm formation (BIC50) was decided by calculating the metabolic activity.The adhesion of C.albicans reduced by catestatin was visualized under an inverted microscope and quantified by colony count.The expression of HWP1 was analyzed by RT-PCR.One-way analysis of variance (ANOVA) and Dunnett's T3 test were used to compare the results.Results Clinical strains and standard strain ATCC 10231 of C.albicans showed strong ability in forming biofilm.Catestatin exhibited MICs ranging from 40 μmol/L to 80 μmol/L against planktonic C.albicans cells,and BIC50 of 80-160 μmol/L in inhibiting C.albicans biofilm formation.Catestatin reduced the adhesion of C.albicans.The colony forming unit (CFU) was 27 822.22-±-2 472.74 in blank control group,while the CFU was 5 355.55± 1 264.03,11 377.78±2 232.58,17 488.89±1 136.27,22 377.78±3 521.99,and 26 044.44±1 329.57 in the presence of 160,80,40,20,and 10 μmol/L catestatin,respectively (F=147.018,P=0.001).The difference between control group and 160,80,and 40 μmol/L catestatin was statistically significant (P＜0.05).RT-PCR found the expression of HWP1 in the presence of 160 μmol/L catestatin was about 12.24％ of that in blank control group.Conclusions Catestatin can effectively prevent C.albicans biofilm formation.This effect may be related to the down-regulated expression of adhesion gene HWP1 by catestatin,which results in reduced adhesion of C.albicans.Promising clinical prospect is expected for this finding.

Objective To determine the normal value and clinical significance of the lengths and angles of both mandible and hyoid, and their relationship with cervical vertebra as well as the transverse area of the airway at the hyoid level using CT. Methods Several lines and angles on the CT images were measured in 68 normal subjects. Line A was the length between both free ends of the mandible; line B was the distance from the body of the mandible to line A; Line C was the distance from line A to the anterior aspect of the cervical vertebra. ?1 was the angle between the middle of mandible body and its two free ends. Line a was the distance between two free ends of greater horn of hyoid bone. Line b was the distance from hyoid to line a. line c was the distance from line a to the cervical vertebra ?2 was the angle between the middle of hyoid body and its two free ends. S stood for the area of the airway at the hyoid level. SPSS 11.5 statistical analysis package was used to analyze the results. Results The average and median distance/angle of various measurements were as follows: bne A was (89. 28?5. 90) mm and 88. 70 mm, line B was (62. 61?5. 78) mm and 62. 50 mm, line C was (9. 29?3. 29) mm and 4. 20 mm, ?1 was (71. 25? 6. 77)? and 71. 05? , line a was (38. 69?6. 07) mm and 39. 90 mm, line b was (28. 79?4. 37) mm and 28.50mm, line c was (1.91?3.03) mm and 1.75 mm, ?2 was (68.47?15.71)? and 66.95?.The average S was (436. 14?160. 37) mm and median was 431. 75mm2. Conclusion It's easy to measure the three lines and the two angles of mandible and hyoid. The measurement is of vital importance in the diagnosis and treatment for obstructive sleep apnea syndrome.

Objective In order to identify cytotoxicity and specificity of the suicide gene systems which vascular endothelial growth factor receptor 2(KDR) and CMV were used as promoters respectively. Methods Two cell lines, HUVEC and CNE-2, one expresses KDR highly,another doesn't, were used as target cells for identifying the cytotoxicity and specificity of recombinant adenoviral vectors with herpes simplex virus thymidine kinase (HSV-tk) gene expression driven by KDR promoter and CMV promoter respectively (pAdKDR-tk and pAdCMV-tk) in Vitro by adding GCV. Results HUVEC and CNE-2 showed similarly sensitivity to GCV when they were transfected by pAdCMV-tk. However, They shown different sensitivity to GCV when they were transfected by pAdKDR-tk. When HUVEC was transfected in high MOI (MOI=100) and concentration of GCV was 50 ?g/ml, The cell growth rate decreased to (23.12?4.90)% .On the contrary, CNE-2 cells growth rate remained as high as (70.46 ?3.27)%. Conclusion Two kinds of cell line CNE-2 and HUVEC can be killed by pAdCMV-tk suicide gene system, but pAdKDR-tk suicide gene system only can kill HUVEC cell line. The result implied that pAdKDR-tk could kill the cells that express KDR specifitly.

OBJECTIVE: To provide anantomical basis for the endoscope-assisted partial superficial parotidectomy via retroauricular hairline approach (EASPRHA) and assess its feasibility and safety. METHOD: The surgical anatomy of retroauricular hairline region and parotid gland region were observed in 15 fresh human cadavers (30 halves). The EASPRHA was performed on 5 human cadavers (10 halves). After the procedure, the related vascular and neural structures were evaluated. RESULT: The retroauricular hairline region extends between superficial musculoaponeurotic system and superficial cervical fascia. On the superficial surface of the upper sternocleidomastoid lie the lesser occipital nerve, the great auricular nerve and the external jugular vein. The bifurcation of great auricular nerve is(22.85 ± 2.01) mm from the bottom of earlobe. The parotid gland region extends between parotidomassteric fascia and parotid gland parenchyma. The facial nerve emerging from the stylomastoid foramen runs across the superficial surface of base of styloid process, passes through the interspace between cartilage of external acoustic meatus and posterior belly of digastric muscle, and enters the parotid gland. The bifurcation of facial nerve trunk is (19.10 ± 3.10)mm from the mastoidale and (39.49 ± 5.78) mm from the mandibular angle. Above the posterior belly of digastric muscle, the posterior auricular artery arises from the posterior wall of the external carotid artery with its main stem running over the superficial surface of facial nerve trunk. In all endoscope-assisted operations, the partial superficial parotidectomy was successful without the need for an additional incision. No major neurovascular damage wasobserved. CONCLUSION A thorough knowledge of the surgical anatomy of retroauricular hairline region and parotid gland region is an essential requirement in performing the safe and feasible EASPRHA.

OBJECTIVE: To investigate the characteristics of adductor spasmodic dysphonia phonatory break in mandarin Chinese and select the stimuli phrases. METHOD: Thirty-eight patients with adductor spasmodic dysphonia were involved in this study. Standard phrase " fù mŭ xīn" and a speech corpus in mandarin Chinese with 229 syllables covering all vowel and constant of mandarin Chinese were selected. Every patient read the phrases above twice in normal speed and comfortable voice. Two auditory perpetual speech pathologists marked phonatory break syllables respectively. The frequency of phonatory break syllables and their located phrases were calculated, rated and described. The phrases including the most phonatory break syllables were selected as stimuli phrases, the phonatory break frequency of which was also higher than that of standard phrase "fù mŭ xīn". RESULT: Phonatory break happened in the reading of all patients. The average number of phonatory break syllables was 14 (3-33). Phonatroy break occurred when saying 177 (77.3%) syllables in the speech corpus. The syllables "guŏ, rén, zāng, diàn, chē, gè, guăn, a, bā, ne, de" broke in 23.1%-41.0% patients. These syllables belonged to the phrases "pĭng guŏ, huŏ chē, shì de, nĭ shì gè hăo rén, wŏ mén shì yŏu zŏng shì bă qĭn shì nong dé hĕn zāng, wŏ mén nà biān yŏu wăng qiú yùn dong chăng, cān gŭan, jiŭ bā hé yī gè miàn bāo dìan, tā shì duō me kāng kăi a,wŏ yīng gāi zài xìn lĭ xiĕ yī xiē shén mē ne?". Thirty-seven patients (97.3%) had phonatory break in above mentioned words. Ratios of these words phonatory break also were more than "fù mŭ xīn". CONCLUSION Adductor spasmodic dysphonic patients exhibited different degrees of phonatory break in mandarine Chinese. The phrases" shì de, pĭng guŏ, huŏ chē, nĭ shì gè hăo rén, wŏ mén nà biān yŏu wăng qiú yùn dong chăng, cān gŭan, jiŭ bā hé yī gè miàn bāo dìan, tā shì duō me kāng kăi a" were recommended as stimuli phrases for adductor spasmodic dysphonia evaluation.
