This paper introduces the definition, contents, methods and deficiencies for medical equipment file management in modern hospital. The importance of file management is also discussed.

To explore the influences of the sterile injectors with different sources while the same capacity on the infusion precision of the syringe pump. With six injects with two brands were selected as the subjects and an electronic pump for measuring, flow test was carried out with the brands marked on the pump or not. There was significant difference between the flows from the syringe pumps marked with the injector brands and those without the mark of the brands. The sterile injector has to be set before using the syringe pump.

This paper presents the definition,characteristics and significance of medical measurement control in modern hospitals.It also clarifies how to found a good medical measurement system.

Aquaporin adipose (AQPap) is the physiological glycerol channel specific to adipocytes. By means of semiquantitive RT-PCR and Western blotting, this study showed that insulin was a negative regulator of AQPap expression, while high concentration of glucose could increase AQPap expression.

Objective To investigate the advantages of emergent ureteroscopy for the treatment of acute obstructive renal failure resulted from upper ureteral calculi.Methods A total of 123 cases of acute renal failure caused by bilateral upper ureteral calculi was treated with ureteroscopic exploration,ballistic lithotripsy,catheter indwelling,and percutaneous nephrolithotomy.Results The serum BUN(blood urea nitrogen) and Cr(creatinine) were decreased to normal levels 2～10 days after operation in 100 cases(81.3%);the levels of Cr were maintained at 188.6～232.3 ?mol/L 10～15 days after operation in 22 cases.In 1 case of congenital solitary kidney(renal failure caused by chronic contralateral ureteral calculous obstruction),a hemodialysis was needed on the 3rd day after operation,and the serum Cr was 810 ?mol/L on the 15th day after operation and was dropped to normal after 2 months postoperatively.In 4 cases of previous unilateral nephrectomy or congenital solitary kidney,azotaemia remained at 3 months after operation.Conclusions Emergent ureteroscopy for acute renal failure caused by calculous obstruction possesses advantages of immediate obstruction relief,effective renal function protection,little trauma,low complication rate,and simple performance.

Metformin has been applied for 50 year.In recent years,new studies found that metformin could reduce glucose through activating inhibition of dipeptidyl peptidase Ⅳ(DPP Ⅳ) and enhancing the biological effect of glucagon-like peptide-1(GLP-1).In addition,metformin can reduce vascular disease risk of patients with type 2 diabetes by improving insulin resistance and the effect of reducing total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),blood coagulation factor Ⅶ,plasminogen activator inhibitor-1(PAI-1) and proteinuria.Merformin can't change blood pressure of patients with type 2 diabetes,however,it can significantly reduce the salt-sensitive blood pressure of patients with obesity.Metformin has also been applied to patients with polycystic ovary syndrome(PCOS).It can induce ovulation,decrease the rate of abortion and have effect on hypertrichosis and hyperandrogenism.Besides,metformin has been the focus of the treatment of non-alcoholic fatty liver disease.

Objective To investigate the bettertherapeutic method and clinical efficacy of discoid meniscus injury under arthroscope.Methods Forty-one patients with discoid meniscus injury were selected as our subjects from Nov.2011 to Feb.2013,who were treated by arthroscopic surgery and performed with meniscus plasty.Thirt-eight patients were received ultra Fast-fix meniscal repair system.Joint function exercises were performed on bed within 1 month after operation.Incomplete weight bearing were performed after 1 month postoperation.After 3 month postoperation,they were permitted for full weight bearing.Results All patients were treated successfully with surgery and no postoperative complications occurred.The patients were followed up from 3.0 to 18.0 months and average was 10.5 months.The preoperative Lysholm scores were(68.28 ±8.04)) lower than that at the postoperation (88.17 ± 7.49)) and the difference were significant (t =11.59,P ＜ 0.05).Furthermore,according to Ikeuchi criterion,the outcomes were 28 cases with excellent,10 cases with good and 3 cases with general rank.Conclusion Discoid meniscus plasty and suture under arthroscope is proved to be a better approach with less trauma,recovery quickly and fewer complications.It should be a preferred method for discoid meniscus injury.

Objective:To explore the surgical techniques in posterolateral mini-incision total hip arthroplasty and clinical effcacy.
Methods:A total of 94 patients (98 hips) had posterolateral mini-incision total hip arthroplasty, from December 2006 to December 2008, and were randomly divided into a posterolateral mini-incision total hip arthroplasty group (Group A) and a conventional group of posterolateral incision for total hip arthroplasty (Group B). Forty-nine patients (50 hips) in Group A had posterolateral small incision total hip arthroplasty [26 males, 23 females, between 37.0 and 95.0 years (average 68.9 years), body mass index (BMI) between 20.3 and 29.7 (average BMI 25.4)]. Forty-ifve patients (48 hips) in Group B had the conventional posterolateral incision [27 males, 18 females, between 45.0 and 92.0 years (average 69.7 years), BMI between 18.7 and 34.1 (average BMI 26.9)]. The incision length, blood loss, drainage, operation time, and postoperative Harris scores were compared between the 2 groups.
Results:The incision length was 6.0~10.5 (average length 7.4) cm, average blood loss was 387.6 (140.0~1000.0) mL, average drainage was 143.1 (63.0~375.0) mL, average blood transfusion was 77.6 (0~400.0) mL, average operation time was 84.6 (63.0~130.0) min, and vitalock abduction angle imaging after the operation was 41.6° (averagely 38.0°~57.0°) in Group A. The incision length was 15.0~23.0 (average length 20.0) cm, average blood loss was 513.1 (210.0~1350.0) mL, average drainage was 152.3 (70.0~520.0) mL, average blood transfusion was 142.2 (0~800.0) mL, average operation time was 84.0 (71.0~115.0) min, and postoperative radiographic acetabular cup abduction angle was 42.3° (37.0°~54.0°) in Group B. The follow-up showed that the prosthesis of the 2 groups was in a good position, Harris score was significantly improved with no complications after total hip arthroplasty in the 2 groups.
Conclusion:With the correct selection of indications and adept operation skills and other circumstances, posterolateral mini-incision total hip arthroplasty may do little damage to the soft tissue with a small scar on the skin. The imaging evaluation after the operation and the Harris score show no difference between the 2 groups. Patients are satisfied with their joint function and postoperative recovery.

Insulin like growth factor-Ⅰ (IGF-Ⅰ) gene was transferred to diabetic rats with intramuscle gene therapy pathway. It was showed that IGF-Ⅰ gene could express in the body and the blood glucose level was significantly decreased with increasing of serum IGF-Ⅰ.

The present paper deals with the effect of impulse noise, which is produced by launching of miniature tactical missiles, on hearing of guinea pigs situated in the control room of the missile launching vehicle. 20 normal hearing guinea pigs are placed in the control room in which impulse noise level is 160-170dB (sound pressure level) and duration is longer than Is. 48h after sound exposure, the mean threshold shift is 2 dB, and threshold shift of 2/40 ears is greater than 10dB. Histological observation reveals that cochlear hair cells are undamaged in 15 ears. Howeves, staining on bloc shows hydrops of cochlear partition in 5 ears.
