Chinese Journal of Practical Nursing 2009;25(29):63-64
Ohjective To know the proper wraping method for postoperative patients with neurosurgical intervention treatment. Methods Divided 94 patients with neurosurgical intervention treatment into the ban-dage group and the gauze group randomly, there were 47 cases in the each group. Bandage and gauze was used in the two groups for punctured wound respectively, and then compared the condition of complications and puncture location between the two groups. Results The incidence rate of puncture-associated comphcations in the bandage group was sinificant lower than that of in the gauze group. Conclusions Wraping by bandage for postoperative patients with neurosurgical intervention treatment is more effective than gauze method.

Seven genes (fabD, fabG, fabH, fabA, fabZ, fabB and fabI) of E.coli fatty acid biosynthetic enzymes were cloned by PCR amplifying and appropriate expression vectors were constructed. Under induction assay expression of plasmid encoded proteins was carried out in strain BL21(DE3) and seven enzymes were purified using Ni-NTA agarose resin. In the absence of [2-14C] malonyl-CoA fatty acid synthetic reaction was reconstituted in vitro by adding seven enzymes and co-factors. And several model reactions were established for identification of special fatty acid biosynthetic enzymes. Meanwhile Clostridium acetobutylicium FabZ function was characterized by this method.

BACKGROUND:In order to avoid heterotopic ossification after total hip arthroplasty, nonsteroidal anti-inflammatory drugs are commonly used for prevention.
OBJECTIVE:To compare the effect of meloxicam and indomethacin in the prevention of heterotopic ossification after total hip arthroplasty.
METHODS:Fifty-one patients who treated in the Department of Orthopedics, the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine from 2010 to 2011 were col ected. Among the 51 patients, nine patients were treated with bilateral total hip arthroplasty, and al the patients had total hip arthroplasty with the posterior-lateral approach. The patients were divided into the control group and the experimental group according to the drugs used after replacement, and the patients in the two groups were administered with indomethacin sustained-release tablet 25 mg+omeprazole capsule 20 mg or meloxicam tablet 15 mg after replacement.
RESULTS AND CONCLUSION:There were no significant differences in the incidence of heterotopic ossification, pain, modified D’Aubigne and Postel scores after replacement between two groups (P>0.05). But, the gastrointestinal adverse reactions of the experimental group were less than those of the control group. The application of meloxicam only can effectively avoid the heterotopic ossification and release pain. Consequently, we recommend meloxicam as postoperative drug for the prevention of heterotopic ossification and pain remission fol owing total hip arthroplasty.

s:Objective Discuss the application of CTA for renal vascular control in laparoscopic renal transplantation of relative renal donors. Methods 83 cases of relative renal transplantation donors which are completed in our department during March 2007 to Junuary 2012 were divided into 3 Groups. There were 35 cases in group A ( laparoscopic nephrectomy with preoperative CTA examination) , 15 cases in group B ( laparoscopic nephrectomy without preoperative CTA examination) , and 33 cases group C ( conventional nephrectomy) . In group A, the location and quantity of renal arteries and veins were observed with preoperative CTA to make plan for vascular control. And the oper-ation time, amount of bleeding, vascular injury cases, the renal warm ischemia time in the graft, mean time of postoperative hospitalization were compared with those of group B and group C. Results 5 cases of renal vascular anomalies were observed in Group A, including 2 cases of single accessory renal artery, 2 cases of early branch of renal artery and 1 case of double renal veins. And all of them were intraoperatively comfirmed. 3 cases of renal vascular anomalies were observed in group B, including 1 case of renal arteriovenous ectopic, 1 case of injury in the accessory renal artery with diameter of 0. 6 cm, and it were given artery elongation with inferior epigastric artery postoperatively, and 1 case of renal vein injure during blocking lumbar vein with Hemolock which were repaired postoperatively. 5 cases of renal vascular anomalies were observed in group C, including 1 case of single accessory renal artery, 3 cases of early branch of renal artery, and 1 case of accessory renal artery with the diameter of 0. 1cm in the right renal was injured during surgery. The operation time, amount of bleeding, cases with vascular injury , renal warm ischemia time of donor , and the mean time of postoperative hospitalization in group A were superior to those in group B and group C. Conclusion CTA is a simple noninvasive imaging method, which can provide the details of the renal vascular preop-eratively to ensure the safety of patients during surgery and improve survival quality of donor renal, and it is of great advance in laparoscopic renal transplantation of living-related renal donors.

This article describes a novel Multifunctional and Transparent Urinary System Model (MTUSM), which can be applied to anatomy teaching, operational training of clinical skills as well as simulated experiments in vitro. This model covers kidneys, ureters, bladder, prostate, male and female urethra, bracket and pedestal, etc. Based on human anatomy structure and parameters, MTUSM consists of two transparent layers i. e. transparent organic glass external layer, which constraints the internal layer and maintains shape of the model, and transparent silica gel internal layer, which possesses perfect elasticity and deformability. It is obvious that this model is preferable in simulating the structure of human urinary system by applying hierarchical fabrication. Meanwhile, the transparent design, which makes the inner structure, internal operations and experiments visual, facilitates teaching instruction and understanding. With the advantages of simple making, high-findelity, unique structure and multiple functions, this model will have a broad application prospect and great practical value.

BACKGROUND: Obtaining synovial fluid for diagnostic test of periprosthetic joint infection is invasive and painful to patients. Platelet count is a regular blood test which has been used as a possible predictor of several infectious diseases. Presumably, it could be one of the indicators of periprosthetic joint infection. OBJECTIVE: To identify the accuracies of platelet combined with white blood cell, erythrocyte sedimentation rate or C-reactive protein in the diagnosis of periprosthetic joint infection. METHODS: Patients undergoing revision arthroplasty from March 2013 to December 2018 in the First Affiliated Hospital of Guangzhou University of Chinese Medicine were retrospectively enrolled. A diagnosis of periprosthetic joint infection was confirmed in 77 patients according to the criterions from the Musculoskeletal Infection Society; the remaining 137 patients were confirmed as aseptic cases. White blood cell, erythrocyte sedimentation rate, or C-reactive protein and platelet count were compared between the two groups. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS AND CONCLUSION: The platelet values were significantly increased in periprosthetic joint infection cases. Sensitivity and specificity of the platelet for periprosthetic joint infection were 64.94% and 86.13%, respectively. Platelet demonstrated a higher accuracy when compared to erythrocyte sedimentation rate and C-reactive protein. In such cases, the platelet shows a certain reference value in confirming the diagnosis of periprosthetic joint infection. Platelet was enough used as adjunct diagnostic tool in patients suspected with periprosthetic joint infection.
