Objective:To forecast Urban Employees' Basic Medical Insurance ( UEBMI) in the next 85 years based on population size, age and gender distribution, and to calculate its sustainability gap. Methods:According to the population policy of Beijing and economic development of the region;based on the data of the sixth census in Bei-jing, the estimation model was constructed, and its parameters were defined and selected. Based on the period of 2010, the future of UEBMI in the next 85 year was predicted based on the population size, age and gender distribu-tion. Results:The population of UEBMI in Beijing will reach the maximum value in 2020, and then the downward trend will increase. The aging rate of the insured population will accelerate year after year and will reach the peak in the middle of this 21st century. The sustainability gap is predicted to reach at least 9541. 35 Billion dollars, and the Beijing municipal government is expected to level an average of at least 44 . 693 billion yuan per year to set aside the financial funds in order to fill the gap, so sustainable development of the fund is ensured. Conclusion:From the point of view of the insured population, there is a huge financial sustainability risk in the future of UEBMI in Beijing.

To investigate the efficacy of electroacupuncture plus TDP irradiation for treating noninfectious urethral syndrome. Method:Sixty patients with noninfectious urethral syndrome were randomly divided into an electroacupuncture plus TDP irradiation treatment group of 40 cases and a medication group of 20 cases as a control. Results:The effective rate was 85% in the treatment group and 35% in the control group. There was a significant difference in curative effect between the treatment and control groups(P＜0.01). Conclusion:Treatment by electroacupuncture plus TDP irradiation has an exact effect on noninfectious urethral syndrome. Its curative effect was significantly better than that in the medication control group.

Objective To compare the effect and safety between lightwand and general-laryngo-scope application of trachea cannula in cervical spine fracture patients undergoing general anesthesia. Methods Forty cervical spine fracture patients with tracheal intubation anesthesia were selected,including twenty-eight males and twelve females,aged 18-65 years,ASA physical statusⅡor Ⅲ.These patients were randomly divided into two groups,twenty cases in each group.After anesthesia induction,group L was giv-en general laryngoscope intubation,whereas group C was taken lightwand guided tracheal intubation.The success case of intubation at first,intubation time,adverse reaction of intubation,changes of MAP and HR at intubation and 5 minutes after intubation were observed.Results Compared with group L,success rate of intubation at first was higher (90% vs.60%),intubation time was shorter [(31.3±11.1)s vs.(46.6 ±15.2)s]in group C (P <0.05).The changes of MAP and HR were more stable during intubation in group C compared with group L.Four cases of arrhythmia (20%)occurred in group C,while none in group L.Conclusion Compared with intubation by general laryngoscope,application of tracheal intubation led by lightwand in cervical fracture patients is more effective and safer.

Vitamin D is a kind of essential nutrient.Besides participating in calcium-phosphate metabolism,vitamin D also plays a role in the immune regulation.Sepsis is a common condition in ICU which can lead to immune disturbance and is associated with high mortality.Vitamin D deficiency in septic patients is more common than in the healthy peers.The mechanism of immune dysfunction in septic patients,the immunomodulatory role of vitamin D,the interaction between vitamin D and immune function were reviewed in this article.

A realizaton project of electrical stimulator aimed at motor dysfunction of stroke is proposed in this paper. Based on neurophysiological biofeedback, this system, using an ARM9 S3C2440 as the core processor, integrates collection and display of surface electromyography (sEMG) signal, as well as neuromuscular electrical stimulation (NMES) into one system. By embedding Linux system, the project is able to use Qt/Embedded as a graphical interface design tool to accomplish the design of stroke rehabilitation apparatus. Experiments showed that this system worked well.

Objective To explore the efficacy of breast-conserving therapy of ductal carcinoma in situ (DCIS),and to evaluate its safety.Methods 54 patients with DCIS receiving breast-conserving therapy(the experimental group) and 49 patients with DCIS treated with mastectomy(the control group) in the First Affiliated Hospital of Wenzhou Medical College from Mar.2010 to Mar.2013 were retrospectively analyzed.The follow-up results of the 2 groups were analyzed in terms of the local recurrence,distant metastasis and the 3-year diseasefree survival(DFS).The efficacy and safety of breast-conserving treatment were evaluated.Results All patients were followed up for 5 months to 39 months,with the average of(22.3 ± 8.5) months.No local recurrence happened in the experimental group.There was 1 case of chest wall recurrence in the control group.One case in the experimental group and 2 cases in the control group had distant metastasis.DFS rate in the 2 groups was 100％ and 95.9％ relatively.No statistically significant difference was found between the 2 group in terms of the above items (P ＞ 0.05).Conclusion For DCIS patients,the difference between breast-conserving therapy and mastectomy surgery in the rate of local recurrence and distant metastasis was not significant.Breast-conserving therapy is safe for DCIS patients and should be further promoted.

0.99).The limits of detection were below 0.5 ?g/L.The rates of recovery for the spiked samples ranged from 70.1% to 117.9% and the relative standard deviations(RSD) were between 0.4%-16.1%.Conclusion The method is simple,rapid,accurate and is applicable to the simultaneous determination of multi-pesticide residues in drinking water.

Objective To choose the best surgical procedure,the surgical results and clinical outcomes of inguinal hernia repair with either an open anterior or posterior approach,were studied.Methods The 366 cases of inguinal hernia patients according to surgical side approach in different ways,is divided into A,B groups,Among group A of 186 cases repaired with application of prolene hernia system (PHS) via anterior approach,while group B of 180 cases surgically treated with Kugel technique with a posterior approach,and surgical procedure,postoperative recovery and complications were compared between these two groups,respectively.Results No significant differences were found in operation time,hospital stay,incisional infection rate and the recurrence rate (P ＞ 0.05).However,compared with group,the group B patients had less pain of the wound,slight postoperative swelling response,less foreign body aesthesis and hydrocele(P ＜ 0.05).Conclusion Compared with the anterior approach surgery,the posterior approach (Kugel technique) has less traumatic,low complication rate and rapid recovery after operation.

Objective To develop the personalized 3D printing scaffolds for bone grafts,to meet the needs of the patients with the bone defect.Methods The model of three-dimensional woodpile structure was designed by the software of computer-aided design (CAD).The β-tricalcium phosphate (β-TCP),hydroxyapatite (HA),and polylactic acid (PLA) composite scaffolds with three-dimensional woodpile structure was simulated using 3D printing method by three-dimensional air floating platform.The three-dimensional bone graft scaffolds was then vacuum heat-treated,and the residual chloroform was detected by energy dispersive X-ray spectrometer.The morphology of the β-TCP/HMPLA scaffolds was characterized by scanning electron microscope,and in vitro cytotoxicity against osteoblasts hFOB 1.19 was assessed by thiazolyl blue tetrazolium bromide (MTT) assay.Results When the extrusion pressure of printing slurry was 137.9-413.7 kPa,the three-dimensional bone graft scaffolds could be printed out.Then the scaffolds was vacuum treated at 90 ℃ and preheated at 150 ℃,which could eliminate the solvent CHC13.The three-dimensional bone graft scaffolds,with a through-hole and rough surface,was co-cultured with osteoblasts hFOB1.19 for 7 d,and it's cytotoxicity grade was grade 0.Conclusions The three-dimensional bone graft scaffolds have a through-hole and rough surface,which is favorable to the osteoblasts culture and bone induction,indicating the advantage and development prospects of 3D printing in the preparation of porous materials for bone grafts.
