The development in the field of microbe is the fastest. in 21st century, the local government and colleges gradually enlarge the support of the ion beam bioengineering, some articles are under the support of enterprise researcher and fund. The contents of these articles mainly about application study. After analysing the data, the future of ion beam bioengineering of China was forecasted.

Objective To observe the relationship between extended spectrum ?-lactumases(ESBLs) bacteria infection and immune factor in children.Methods Immune function were tested in 49 children with ESBLs infection,that the test of ESBLs changed from negative to positive in hospital and compared with that of ESBLs bacteria negative infected case,children with hypoimmunity and normal immune function.Results Forty-nine cases of ESBLs bacteria positive-changed children had lower immune function and their immune function improved when restored.The rate of ESBLs positive-changed was significant higher in hypoimmunity than that of normals(P

RAPD molecular marker was widely applied to the studies of edible fungi due to it’s simplicity , rapidity and economy. The principle of RAPD molecular marker and its applications to edible fungi were summarized. The applications of RAPD to edible fungi were introduced in species and parental strain identification,genetic diversity, gene clone, gene isolation and the construction of gene linkage map. RAPD molecular marker provids a powerful tool for the studies of edible fungi.

AIM: To observe the curative effect of PDT combined with intravitreal injection of ranibizumab treatment for age-related macular degeneration with choroidal neovascularization ( CNV) .
METHODS:In accordance with the inclusion criteria, by indocyanine green choroidalangiography ( ICGA ) and optical coherence tomography ( OCT ) examination confirmed the diagnosis of macular CNV in 27 patients (27 eyes), treated with PDT 3 ~ 7d professional intravitreal injection of ranibizumab. At 1, 3, 6mo after treatment, the results of best corrected visual acuity (BCVA), FFA, ICGA, OCT examination and complications were observed.
RESULTS: The BCVA improved in 17 eyes ( 63%) , stable in 6 eyes ( 22%) , and decreased in 4 eyes ( 15%) . Before treatment, the average leakage area was 1 005. 69±105. 47μm, it were 875. 54 ± 103. 27μm, and 423. 37 ±79.68μm at 1 and 3mo after treatment, there were significant differences compared with before treatment ( P<0. 01). Average central macular thickness of retina before treatment was 485. 58±122. 59μm, and 398. 84±105. 32μm, 297. 74±89. 18μ m at 1 and 3mo after treatment, there were significant differences compared with before treatment( P<0. 01).
CONCLUSION: The method that PDT closed CNV combined with intravitreal injection of ranibizumab can effectively block angiogenesis recurrence, reduce the number of PDT treatment again and complications, improve the therapeutic effect.

Objective To observe the influence of nape acupuncture therapy on swallowing function of patients with cerebral infarction. Methods Eighty patients with dysphagia after cerebral infarction were recruited and randomly allocated to the nape acupuncture group and the control group, 40 each group. Both groups were given general medicine therapy and swallowing functional training, while the nape acupuncture group was given nape acupuncture based on the control group, and fiberoptic nasopharyngoscopy was used for the swallowing function before and after treatment. Rosenbek Penetration-Aspiration Scale (PAS) score of 5ml pudding food, 5ml and 10ml liquid food, and the scores for bedside water-swallowing test and standardized swallowing assessment (SSA) were obtained. Before and after treatment, the differences between the two groups were identified respectively. Results After treatment, the scores of SSA and PAS of swallowing of 3 kinds of food in both groups were significantly improved compared with those before treatment (P<0.05). The improvement of SSA and PAS scores of 5ml and 10ml liquid food in the nape acupuncture group were superior to the control group (P<0.05). The total effective rate of the nape acupunture group was significantly higher than that of control group (χ2=5.00, P<0.05). Conclusion Nape acupuncture therapy may significantly improve the swallowing function of patients with dysphagia following cerebral infarction.

Educational informationization is the focus of education and teaching reform. World University Town provided a very good platform for information and network teaching. This paper, taking the community rehabilitation course as an example, introduced the function ofWorld University Town in course construction and described the concepts, ideas, procedures and application effect.

AlM: To observe the therapeutic effects of improved external dacryocystorhinostomy.
METHODS:Retrospective analysis on 94 patients with monocular chronic dacryocystitis in our hospital from October 2010 to December 2013 were taken the improved external dacryocystorhinostomy. The improved surgery which was based on the traditional surgery including: 1. Nasal packing after anesthesia to relieve the pain and bleeding; 2. Not cut the medial palpebral ligament; 3. Suture the upper membrane of the nasal mucosa only;4. Pipe placement;5. Skin layered hairdressing suture. The patients were follow-up 3mo-2a after operation.
RESULTS: Ninety-three cases of patients cured with completely asymptomatic, no epiphora or mucopurulent secretion flow out from the lacrimal punctum, unobstructed lacrimal irrigation, the efficiency is 99%, 1 case of patient was epiphora, obstructed lacrimal irrigation, 1% was invalid.
CONCLUSlON:The improved external dacryocystorhinostomy is an effective surgical method which is easy to operate with high cure rate and its long term effect is precise.

Objective To study the biological exposure limit in bone metabolism damage caused by coexposure to fluorine and arsenic from coal burning in exposed population.Methods One hundred and ninety-eight cases of fluoride and arsenic co-exposed people from Liuchang village,Qinzhen city,Guizhou province were enrolled in the study.Urinary fluorine (UF),urinary arsenic (UAs),urinary hydroxyproline (UHYP),ross-linked Ntelopeptides of type Ⅰ collagen(UNTX) and bone strength index(STI) were detected.BMDS Version 2.1 software was used to calculate UF,UAs benchmark dose (BMD) and its lower confidence limit (BMDL) on the damage of bone metabolism caused by co-exposure to fluorine and arsenic from coal burning.Results The BMD and BMDL range of UF caused by co-exposure to fluorine and arsenic from coal burning were 0.68-1.35 mg/g Cr,0.57-1.11 mg/g Cr.The BMD and BMDL range of UAs caused by co-exposure to fluorine and arsenic from coal burning were 8.36-18.77 μg/g Cr,7.12-15.40 μg/g Cr.Conclusion The biological exposure limits of UF and UAs for bone metabolism toxicity are proposed as 0.57 mg/g Cr and 7.12 μg/g Cr in co-exposure to fluoride and arsenic from coal burning,respectively.

OBJECTIVETo compare the efficacy differences between fire needling therapy and oxycycline tablets for the treatment of moderate to severe acne vulgaris.

METHODSSixty cases of moderate to severe acne vulgaris were randomly divided into a fire needling group and a medication group, 30 cases in each one. The pricking method of fire needling at Ashi points around damaged skin was applied in the fire needling group, once every five days for totally 4 times. The oral administration of oxycycline tablets, 100 mg, was applied in the medication group, twice daily for 20 days, also external application of adapalene gel before sleep was adopted. The fading time of skin damage, including papule, pustule, nodule and cyst in the two groups was recorded and clinical efficacy was compared. After the treatment, two-month follow-up was performed to observe the recurrence rate in the two groups.

RESULTSThe curative rate was 69.0% (20/29) in the fire needling group, which was statistically different from 40.0% (12/30) in the medication group (P < 0.05). The fading time of each type of skin damage in the fire needling group was shorter than that in the medication group [papule: (2.67 +/- 0.66) d vs (4.36 +/- 0.61) d; pustule: (2.47 +/- 0.57) d vs (4.27 +/- 0.55) d; nodule: (7.76 +/- 1.06) d vs (9.88-1.30) d; cyst: (11.81 +/- 1.54) d vs (14.79 +/- 0.89) d, all P < 0.05]. The recurrence rate was 46.4% (13/28) in the fire needling group, which was not significantly different from 44.0% (11/24) in the medication group (P > 0.05).

CONCLUSIONThe acne vulgaris could be fast and effectively treated by fire needling therapy, which has shorter fading time than oxycycline tablets. However, the preventive effect is not different between the two theraies.
