Respirator is one of medical equipment in the first-aid, the clinical risk of it is much higher than the general medical equipment and diagnostic or patient monitor equipment. As a result, the quality control of it is particularly important. Several issues of the quality control of the respirator, such as the pre -purchase technical feasibility study, acceptance and installation after arrival, respirator use and management, respirator-reported loss demonstration and cost- benefit analysis of it are discussed from the angle of clinical engineers and technical personnel.

A new retinoscope with the ultrasonic distance measure instrument is designed for directly displaying the dioptre of artificial myopia caused by retinoscopy distance.Optometrist can obtain real dioptre of the patient if only adding the direct dioptre of artificial myopia to neutral dioptre obtained at roll-back point.This instrument can obviously increase the accuracy of refraction.

Objective The PRESENT ( Physicians' Routine Evaluation of Safety and Efficacy of NovoMix 30 Therapy) study is a multinational clinical experience program to report the efficacy, safety and acceptability of NovoMix 30 (BlAsp 30) in patients with type 2 diabetes mellitus inadequately controlled with oral antidiabetic drugs (OADs). Methods A total of 4 754 type 2 diabetes patients inadequately controlled with oral antidiabetic drugs were enrolled in the study. All patients were prescribed BIAsp 30 in accordance with the approved labeling. Data were collected at baseline and at the end of 3 months treatment. Results The mean HbA1c, body mass index (BMI), age, and duration were (9.09±1.70)%, (24.30±2.68)kg/m2, (54.63±10.94)years, and (5.46 ±4.17) years separately. The mean daily dose was (0.43±0.14) U/kg at treatment initiation and (0.48±0.15) U/kg after 3 months treatment. After 3 months, the mean HbA1c, fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) were significantly reduced from baseline levels. The mean HbA1c decreased by (2.04± 1.57)%, FPG by a (3.51±2.55)retool/L, and PPG by a (6.51±4.02) mmol/L (all P<0.01). A significant proportion (49.4%) of the patients achieved target HbA1c of ≤7%. The overall rate of hypoglycaemic episodes (events/patient-yr) decreased from 10. 098 at baseline to 3. 810 at study end. The rate of major hypoglycaemia decreased from 0. 787 to 0.126, and the rate of nocturnal hypoglycaemia decreased from 2.356 to 0.547. Compared with previous treatment, more than 99% of the patients and physicians were "satisfied" or "very satisfied" with BIAsp 30 treatment. Conclusions BIAsp 30 was found to be safe and effective to improve the glycaemia control of type 2 diabetes inadequately controlled with OADs in routine clinical practice.

To evaluate the clinical effects of rotary nickel-titanium instruments Mtwo in root canal therapy in the aged patients. Using step-back technique,80 teeth with pulpal and periapical involvement were instrumented by Mtwo in the M group, and by K file in the K group. Mtwo could keep the original curvature and flow of the root canals. No transportation, apical blockage, ledge or perforation was found in the M group. There was more complications in the K group than in the M group.The operative time was shorter and posttreatment pain seldom occurred in the M group. With rotary NiTi instruments Mtwo for seniles' root canals treatment, root canals can be prepared effectively and quickly,and is worth of clinical application.

BACKGROUND:Traditional analgesia method can relieve the pain after total knee arthroplasty, but the prognosis is poor and drug dependence is strong. Therefore, it is of great significance to study the analgesic drugs in perioperative period of total knee arthroplasty. OBJECTIVE:To explore the analgesic effect of gabapentin combined with continuous femoral nerve block on total knee arthroplasty. METHODS: A total of 48 patients with knee osteoarthritis receiving total knee arthroplasty in the Department of Orthopedics, Affiliated Hospital of Inner Mongolia Medical University from October 2013 to October 2014 were enroled in this study. Using general anesthesia, femoral nerve block was conducted before anesthesia. Analgesia pump was connected after arthroplasty. Patients were randomized to two groups. The control group received multimodal analgesia, and the experimental group received gabapentin combined with continuous femoral nerve block analgesia. Patient’s pain was scored by using resting, activity visual analog scale. Postoperative quality of life, range of motion of knee joint and complications were observed. RESULTS AND CONCLUSION:No significant difference in preoperative resting pain and activity pain was detected between the two groups (P > 0.05). Visual analog scale scores were decreased with time prolonged after arthroplasty in both groups. Visual analog scale scores of resting pain and activity pain were significantly lower in the experimental group than in the control group at 1, 3 and 7 days and 1 month (P < 0.05). Range of motion was significantly larger in the experimental group than in the control group at 3-7 days after arthroplasty (P< 0.05). Activity of daily living score, physical function score, mental function score and social function score were significantly higher in the experimental group than in the control group (P < 0.05). The complication rate was significantly lower in the experimental group than in the control group (17%, 46%,P < 0.05). These data indicate that during perioperative period of total knee arthroplasty, analgesic effect of gabapentin combined with continuous femoral nerve block is ideal. In particular, in patients with acute pain within 48 hours, their combination can promote early rehabilitation of the patient’s knee, and few side effects are found.

Objective To investigate the clinical features,pathology and prognostic factors of young patients with cervical cancer less than 35 years old.Methods One hundred and twenty cases cervical cancer less than 35 years old were selected as study group,while 120 cases of cervical cancer over 35 years old as control group in the same period.The clinical features and pathology were compared between two groups and risk factors were analyzed.Results The proportion of contact vaginal bleeding,menstrual disorders,mild cervical erosion,HPV infection,and the number of pregnancy preserving ovarian surgery in study group were significantly higher than that in control group(60.8％(73/120)vs.47.5％(57/120),30.0％(36/120)vs.11.7％(14/120),57.5％(69/120)vs.23.3％(28/120),81.7％(98/120)vs.60.0％(72/120),52.5％(63/120)vs.25.8％(31/120)),the differences were statistically significant(x2=4.30,12.23,29.90,13.63,17.91;P＜0.05).The incidence of irregular vaginal bleeding in study group was significantly lower than that in control group(6.7％(8/120)vs.15.8％(19/120)),the differences was statistically significant(x2=5.05,P＜0.05).The main pathological types of two groups were squamous cell carcinoma,non squamous cell carcinoma rate in study group was significantly higher than that in control group(27.5％(33/120)vs.15.0％(18/120)),the differences was statistically significant(x2=5.60,P＜0.05).Pelvic lymph node metastasis rate in study group was 68.3％(82/120),significantly higher than that in control group(55.0％(66/120),x2=4.49,P＜0.05).Multivariate analysis of prognostic factors in young patients with cervical cancer showed that clinical stage,pathological type,depth of cervical invasion and pelvic lymph node metastasis were independent risk factors for the prognosis of young patients with cervical cancer(Wald x2=4.02,6.93,8.92,10.87;OR=3.22,5.57,6.84,5.48;95％CI=1.13-8.62,1.24-11.75,2.82-17.35,1.88-12.35,P＜0.05).Conclusion There are some differences in the clinical features and pathological characteristics of young patients with cervical cancer and middle-aged and elderly patients with cervical cancer.More attention should be paid on the high clinical staging,non squamous cell carcinoma,deep cervical infiltration positive pelvic lymph node metastasis patients,focus on the investigation and prevention,improve the individual treatment and prevention and control system.
