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.

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.

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 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.

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.

ObjectiveTo investigate the effect of neoadjuvant chemotherapy in locally advanced cervical cancer on cell cycle,proliferation,and evaluate the feasibility of proportion of cell in different phase 　and proliferating cell nuclear antigen(PCNA) as sensitive indices to assess chemotherapeutical sensitivity and therapeutical effect.MethodsForty-nine cases of locally advanced cervical cancer were divided into response group and no-response group according to the clinical efficacy of neoadjuvant chemotherapy.Compared the proportion of cell in different phase and proliferation index of PCNA between two groups.The clinical therapeutic effect was evaluated after 4 weeks in the second neoadjuvant chemotherapy regimen.Results In 49 patients with locally advanced cervical cancer,clinical effective of 39 cases (response group),no effective of 10 cases(no-response group).The S-phase proportion of cell in the pre-neoadjuvant chemotherapy and post-neoadjuvant chemotherapy of response group[ (21.47 ± 5.21 )％ and(18.32 ±5.07)％] were higher than those of no-response group [ (9.63 ± 2.58)％ and ( 10.14 ± 2.32)％ ] (P ＜ 0.05 ).The proliferation index of PCNA of cervical cancer in the pre-neoadjuvant chemotherapy of response group [ ( 81.67 ± 7.14)％ ] was higher than that of no-response group [ (66.99 ± 2.29 )％ ] (P ＜ 0.05 ).Conclusion The S-phase proportion of cell and proliferation index of PCNA in the pre-neoadjuvant chemotherapy are important indexes to assess chemotherapeutical sensitivity and therapeutical effect.

Objective To analyse the clinical characteristics,gene mutation and enzymatic activity of αgalactosidase A(α-GalA)in a 15-year-old male patient with typical Fabry disease,whose mother was without any clinical manifestations.Methods Clinical features and laboratory data were collected from the patient and his mother.Genomie DNA was extracted from peripheral blood of the patient.his mother,and a healthy control subject.Seven exons of the GLA gene were amplified by PCR.PCR products were purified.cloned into T vector,and then sequenced.The enzymatic activity of α-GalA Was measured by fluorimetrie substrate assay. Results DNA sequencing results showed that a missense mutation of 10036-10038delAAG in exon 7 WaS identified in the patient,resulting in the replacement of 374 lysine and 375 glyeine by arginine,which Was not previously reported.The patient Was a hemizygote with gene mutation,his mother WaS a heterozygote carrying gene mutation,and the healthy control without mutation.α-GalA enzymatic activity assay showed that the enzymatic activity of the patient with GLA gene mutation was only 50%of the healthy control subject,while the enzymatic activity of the patient's mother Was about 70%of the heahhy control SObject.Conclusiolls Detecting GLA gene mutation and α-GalA enzymatic activity in patients with Fabry disease who have been clinically diagnosed seelns to be helpful in finding other patients in the family and in further understanding the molecular pathogenesis of that disease.
