OBJECTIVETo evaluate the clinical results of Triple-Endobutton plates for the treatment of Rockwood type III to V acromioclavicular joint dislocation.

METHODSFrom March 2008 to June 2010,28 patients with Rockwood type II to V acromioclavicular joint dislocations were treated with Triple-Endobutton plates. There were 18 males and 10 females,ranging in age from 20 to 60 years old (averaged 38 years old). Twenty patients had dislocations in the left and 8 patients had dislocations in the right. All the patients had close injury. The Constant criterion was used to evaluate shoulder joint function.

RESULTSAll the patients were followed up,and the duration ranged from 18 to 24 months,with an average of 20 months. All the patients got good shoulder joint function,and no re-dislocation and pain occurred. The X-ray showed all acromioclavicular joints got good reduction. According to Constant criterion,preoperative score was 25.4 +/- 2.0, postoperative scores were 65.9 +/- 3.0, 87.2 +/- 3.2 and 95.7+/- 1.6 at 1 month,3 months and 6 months separately.

CONCLUSIONTreatment of Rockwood type III to V acromioclavicular joint dislocation with Triple-Endobutton plates has satisfactory clinical outcome, simple operation, few complications, without secondary operation and early functional exercise postoperatively.

Objective:To observe the acoustic characteristics of glottal stops produced by patients with cleft palate.Methods:Twenty boys with cleft palate who were judged to be glottal-stop-producers and 20 normal peers were included. In their own way, all the children were asked to produce following sounds: /iu/ /pai/ /t′u/, /s/ /k′/ /p′u/ /t′u/, /tA/ /ku/ and /i/ /k′u/ /ti/ /suan/. Then the speech spectroanalysis and the comparison were performed by one investigator.Results:The acoustic characteristics of glottal stops changed a lot when they substitute or accompany with different oral stops, which included the emergence of spikes, changes of voice onset time, the formant transitions and spetroanalysis of spikes. Conclusion:The acoustic changes of glottal stops are complicated. Every single aspects of acoustic analysis should be considered in the identification of the acoustic characteristics.

Objective To explore the surgical method, clinical result, biomechanical property, and surgical indication of treatment of thoracolumbar burst fractures with titanium mesh fusion device. Methods 22 patients with the thoracolumbar burst fracture and paralysis were treated by anterior decompression and spinal stability reconstruction with titanium mesh fusion device and a titanium plate. In this group, the fracture was at the 12th thoracic vertebra in 7 cases, the 1st lumbar in 14, and the 2nd lumbar in 1. According to Frankel’s classification, 4 cases were of Grade A, 6 of Grade B, and 12 of Grade C. 20 patients experienced the kyphosis deformity. The kyphosis angles varied from 12 to 29 degrees with a mean of 19.5 degrees. Results The period of postoperative follow up varied from 0.6 to 2 years with an average of 1.2 years. The neural function was improved for more than 1 grade. 15 cases could control urination after the surgery. The kyphosis angles were reduced to 3 to 8 degrees with a mean of 5 degrees. The complications caused by the implants were not found. Conclusions To treat the thoracolumbar burst fractures with paralysis, the compressive elements from anterior side of the spinal cord should be completely removed. Since the titanium mesh fusion device plus a plate can reconstruct the spinal stability that satisfies spinal biomechanical property, it presents important application value.

Objective To explore the effect of different processing and drying methods of corn and hot pepper on fluorine content in coal-burning type of the endemic fluorosis areas, and to screen food processing and drying methods which meet the quality requirements of grain drying and able to effectively reduce the total fluoride intake of local population. Methods Farmers of endemic fluorosis area in Bijie, Guizhou province were divided into 3 groups: sun-baked drying group, stove drying group with air-tight cover and stove drying group with no cover, 10 households in each group. Corn and fresh hot pepper and samples dried for 2 weeks, or 1, 3, 6-month were collected, and water and fluoride content were detected, and the total daily fluoride intake were calculated in accordance with the "Determination of Water in Food" (GB/T 5009.3-2003) and "Determination of Fluorine in Foods"(GB/T 5009.18-2003). Results Fluoride content in fresh corn and dried for 2 weeks, or 1, 3, 6-month [of sunbaked drying group: (1.40 ± 0.16), (1.56 ± 0.14), (2.15 ± 0.47), (2.70 ± 0.64), (4.06 ± 1.75)mg/kg, stove drying group with air-tight cover: (1.41 ± 0.16), (2.39 ± 0.56), (4.60 ± 0.97), (8.46 ± 5.55), (11.36 ± 3.60)mg/kg,stove drying group with no cover: (1.40 ± 0.13), (4.69 ± 3.97), (4.47 ± 2.77), (9.65 ± 6.47), (26.12 ± 14.52)mg/kg] and pepper[sun-baked drying group: (5.41 ± 1.61), (16.60 ± 7.62), (32.60 ± 7.88), (50.26 ± 17.60),(240.20 ± 272.49)mg/kg, stove drying group with air-tight cover: (754 ± 2.95), (3238 ± 11.50), (119.18 ± 156.45),(224.00 ± 196.58), (495.70 ± 417.29)mg/kg, stove drying group with no cover: (4.82 ± 1.25), (44.30 ± 13.48),(122.89 ± 66.43), (334.23 ± 166.05), (531.01 ± 397.40)mg/kg] increased with elongation of drying time, and the group difference was significant(F = 44.77, 128.71, 126.87, 41.61, 53.63, 170.63, all P ＜ 0.05), with the largest rate of increase in stove drying group with no cover, and the lowest in sun-baked drying group;fluoride was significantly lower (t = 7.93,63.07,5.36,11.98,55.76,7.45, all P ＜ 0.05) after sample washing;total fluoride intake per person per day was 2.57 mg in local adult when ate washed and sun-baked corn, peppers, the total fluoride intake were 5.92, 8.14 mg when ate the food processed by other two drying methods and washed corn, peppers,respectively. Conclusions In the coal-burning type of fluorosis endemic area, should take appropriate health education measures, and instruct local residents to use sun bake their edible corn and pepper for human consumption, and cultivate a habit of washing corn and pepper before cooking, which can reduce the population total fluoride intake, and control endemic fluorosis.

Objective To systematically review the evidence for the effect of vitamin D supplementation on insulin resistance and blood glucose in people who are obese or people with abnormal glucose metabolism. Methods We searched databases including Pubmed, Elsevier, Web of Science, and WANFANG Database etc. for randomized controlled trials comparing vitamin D or analogues with placebo. We extracted data on insulin resistance and blood glucose, including homeostasis model assessment of insulin resistance( HOMA-IR), fasting blood glucose, HbA1C (% ). A1l data were analyzed using Review Manager 5. 0. Results Nine studies involving 867 participants were included. The results of meta-analysis showed that: ( 1 ) For people who are obese and with abnormal glucose metabolism, meta-analysis showed a small improvement in HOMA-IR(SMD -0. 34,95% CI -0. 61 to -0. 06, P<0. 05) and a small effect on fasting glucose (SMD -0. 41 mmol/ L, 95% CI -0. 68 to -0. 15, P<0. 05),while such effects were not seen in people who are obese but with normal blood glucose. (2) No serious adverse events were associated with the administration of vitamin D. Conclusion vitamin D supplementation may be benefit for improving insulin resistance and fasting blood glucose in people who are obese and with abnormal glucose metabolism, but has no effect on obese people with normal blood glucose.

Objective To explore the shielding effect that Tween has made on the erythrocyte’ s surface antigen( ABO and D antigen mainly) and the stability of the RBC. Methods Various types red blood cells’ surface antigens were incubated with different concentrations of Tween,then the titers of RBC’ s surface antigen before and after incubation were compared. The erythrocyte’ s function alterations and sta-bility through the morphological obersavation,the osmotic fragility,RBC’ s own hemolysis rate,oxygen saturation( SO2 ) ,routine test of blood as well as the supernatant of free hemoglobin determination were confirmed. Results The masking effect of the Tween-20 on D antigen with the weaken titer keeping above“ +” was better and more stable than that on A,B antigen. The impact on B antigen was a little worse,and A was the worst. The advantaged concentration is about 0. 004%. Besides,the influence of Tween-80’s on B and D antigen was not apparent e-nough. Among all of the concentration,0. 74% and 0. 80% did a relatively better job,which also could keep the weaken titer above “ +”. Conclulsion The shielding effect that Tween has made on the erythrocyte’ s surface antigen( ABO and D antigen mainly) is stable,which keeps above “ +”. The morphology and function of the RBC does not change.
