The overuse of drugs and the irrational increase in medical expenses are currently hot social issues. Standards need to be set in a strict way so as to reasonably contain the cost of medical and health care and die prices of drugs and to lower the expenses of medical services. Analyses conducted in our hospital indicate that the component ratio of the drug income fell from 48.1% in January through June, 2001 to 38.7% one year later; the hospital's overall income in January through June, 2002 dropped 5.3% as compared with the same period of 2001, with the drug income dropping 23.7% and the medical treatment income rising 11.8%; the average expenses bom by emergency outpatients and discharged patients in January through June, 2002 both lowered as compared with the same period of 2001. The authors hold that the component ratio of the drug income ought to be a key index in assessing the integrated management Wei of a hospital; the proportion of the drug income in the overall income of a hospital ought to be restricted to 40% or so; and when general plans are being made for a hospital as a whole with regard to the proportion of the drug income, different standards ought to be set for various specialties.

Objective To evaluate the adjunctive therapeutic effect of intravenous immunoglobulin (IVIG) therapy in the pulmonary infection after kidney transplantation.Methods In 14 cases of pulmonary infection after kidney transplantation, 8 and 6 cases were subjected to high dose (7 to 10 days, group A) or low dose (3 to 7 days, group B) of IVIG therapy besides the standard specific anti-pathogen therapy. In 12 cases of pulmonary infection after kidney transplantation, only standard specific anti-pathogen therapy was given (group C). The incidence and mortality of severe pulmonary infection, levels of serum IgG, IgA, IgM and T lymphocyte subsets among the three groups were observed.Results The incidence of severe pulmonary infection was 0, 66.7 % and 66.7 % respectively in groups A, B and C with the mortality being 0, 16.7 % and 25.0 % respectively. The level of serum IgG was significantly increased in group A after treatment as compared with that before treatment and in group B ( P 0.05 ).Conclusion As an adjunctive therapy, high dose of IVIG at early stage of pulmonary infection can reduce the incidence of severe pulmonary infection and mortality after kidney transplantation.

[Objective]To introduce a new technique of ankle arthrodesis with trephine by lateral approach and evaluate its clinical effects.[Method]Ankle arthrodesis with trephine was performed in 20 patients with serious lesions.Lateral incision was adopted and osteotomy of fibula facilitated the exposure of the fusion site.A trephine of appropriate diameter was used for bi-osteotomy,thus inside the trephine gaining two bone blocks were then rotated 90? and replanted in situ.The pruned fibula was fixed with screws as on-lay!grafting.Proper cast was utilized postoperatively to maintain a functional position.[Result]The average follow-up period was 26 months(ranged from 6 months to 4 years).All the wounds healed well at 2 weeks and the callus appeared 4 weeks postoperatively.Sufficient pain relief was obtained in all patients at 12 weeks and appearance improved greatly.A solid union was achieved in all cases through the radiograph.[Conclusion]The use of trephine in ankle fusion by lateral approach is proved to be a simple technique with high union rate.The main advantages of the technique over other methods of arthrodesis include: excellent exposure by regular incision;less disturbance of the original joint,thereby preserving normal height of the joint and length of the extremity;no need for extra graft through in-situ grafting of the bone blocks and rigid on-lay grafting of lateral malleolus for high primary stability.

Objective To evaluate the using and results of computer-aided detection for full-field digital mammography in Chinese women. Methods 934 individuals more than 40 years old from a specific unit in Shenyang city were screened by full-field digital mammography ( Senographe 2000D, GE) . The examination images were diagnosed firstly by the experienced radiologists and then were analyzed by the computer-aided detection system ( R2' Image Checker ) , respectively. The results from these two assays were compared. Results The prompts were generated in 799 out of 1734 normal images, false-positive rate of computer-aided detection ( CAD) was 46. 1 % in the cases with normal breast image. The correct prompts rate was 70. 5 % in the cases with breast mass, 75. 0 % in the cases with breast microcalcification and 100. 0 % in the cases with breast cancer. Conclusion Although the CAD system has showed clinical values in practice, there are still some false-positive and false-negative results.

Objective: Our aim was to investigate the alteration of p16 gene in human pancreatic carcinoma. Methods: A total of 66 human pancreatic tissue specimens, comprising 51 with pancreatic carcinomas and 15 normal pancreatic tissue specimens, were examined for homozygous deletion and mutation of p16 gene by using PCR-SSCP method. Results: No mutation and deletion was detected in 15 normal pancreatic tissue samples. Of 51 pancreatic carcinoma specimens, only one was found mutation for p16 gene in PCR-SSCP assay, and the deletion of the p16 gene in 23 samples were confirmed by using PCR, with a 45% p16 gene deletion rate. Conclusion: These data suggest that p16 gene alterations may play a role in the progression of human pancreatic carcinoma.

0. 05) . Conclusion Despite immersing in seawater and in freshwater worsen the ALI after open chest trauma,the ALI induced by seawater-immersion is severer than that caused by freshwater-immersion. It is attributed to higher plasma osmotic pressure and abundance of salts after seawater immersion,which increasing the pulmonary penetration index and aggravating the inflammatory response.

ObjectiveTo explore the value of the diagnosis of breast cancer by acoustic elastography, conventional ultrasonography (including gray-scale ultrasonography, color Doppler flow imaging and Doppler spectrum) and mammography.MethodsOne hundred and four patients with breast disease conifrmed by surgical pathology were studied retrospectively in Zibo Maternal and Children Health Hospital. All the patients were examined by acoustic elastography, conventional ultrasonography and mammography before surgery.ResultsPathological results of 104 cases were: sixty-five malignanies and 39 benignities. The most common signs in the diagnosis of breast cancer by conventional ultrasonography were spicule sign (76.9%, 50/65), taller-than-wide sign (73.8%, 48/65), vascular resistance index>0.7 (70.8%, 46/65), calciifcation (53.8%, 35/65). And breast masses without these signs were regarded as benign lesions. The diagnostic criteria of breast cancer by acoustic elastography was 5-point method. We regarded the lesions got more than 3 points as malignancy. The most common signs in the diagnosis of breast cancer by mammography were dense shadow (73.8%, 48/65), spicule sign (70.8%, 46/65), calcification (69.2%, 45/65). And breast masses without these signs were regarded as benign lesions. The diagnostic accuracy of acoustic elastography, conventional ultrasonography, mammography, conventional ultrasound plus acoustic elastography, conventional ultrasound plus mammography and acoustic elastography plus mammography for breast tumor were 88.4% (92/104), 86.5% (90/104), 83.7% (87/104), 93.3% (97/104), 90.4% (94/104) and 89.4% (93/104), respectively. ConclusionsThe combination of any two imaging modalities can improve the diagnostic accuracy of breast cancer. And conventional ultrasound combined with acoustic elastography could be an effective method in the diagnosis of breast cancer.

BACKGROUND:Increasing studies have found that, percutaneous vertebroplasty and bone cement are characterized by few traumas, few bleeding, simple operation, rapid recovery, rapid pain relief, and effective efficacy. However, tumor recurrence, symptom improvement, bone cement leakage and other complications make people controversial. OBJECTIVE: To explore and summarize clinical outcomes and safety of percutaneous vertebroplasty and bone cement for treating symptomatic vertebral hemangioma. METHODS:Fifty-two cases patients of symptomatic vertebral hemangioma (including 21 male and 31 female, aged 16-63 years) were treated with percutaneous vertebroplasty and bone cement. The lesions were found at T5-T12 in 36 cases and at L1-L3 RESULTS AND CONCLUSION: Al 52 patients were folowed up for at least 6 months after the operation. The Visual Analogue Scale and Oswestry Disability Index were significantly increased at 1 day, 3 weeks and 6 months post-surgery, when compared to before surgery (P< 0.05); the modified Macnab evaluation was excelent in 40 cases, good in 7 cases, fair in 3 cases, and poor in 2 cases, and the excelent and good rate was 90%. Only one patient had recurrence at 6 months after surgery and one patient had the leakage of bone cement. No other complications were found. Percutaneous vertebroplasty and bone cement could effectively cure vertebral hemangioma and relieve the pain, which is a safe treatment. in 16 cases. Clinical outcomes such as Visual Analogue Scale, Oswestry Disability Index and modified Macnab criteria, as wel as complication before and after surgery were evaluated.

Objective To observe the difference of vascular endothelial growth factor (VEGF) and myeloperoxidase (MPO) between diabetic and non-diabetic patients with maintenance hemodialysis (MHD),and to explore whether it was associated with duration of hemodialysis.Methods A total of 120 patients with MHD were divided into diabetic group (40 cases) and non-diabetic group (80 cases) according to the primary disease.The blood samples from the patients before dialysis were selected to test the serum VEGF and plasma MPO and other indicators.The blood samples from April 2012 to March 2013 were labeled diabetic group 1(40 cases) and non-diabetic group 1 (80 cases).The blood samples from April 2013 to March 2014 were labeled diabetic group 2 (40 cases) and non-diabetic group 2 (80 cases).Results The serum VEGF and plasma MPO levels were (74.63 ± 47.43) ng/L,(300.63 ± 235.37) μ g/L in diabetic group 1,and (63.69 ± 43.23) ng/L,(275.35 ± 216.32) μ g/L in non-diabetic group 1,and there were significant differences between two groups (P ＜ 0.05).The serum VEGF and plasma MPO levels were (83.32 ± 40.38) ng/L,(414.12 ±265.52) μg/L in diabetic group 2,and (70.89 ±39.74) rig/L,(289.45 ±202.85) μg/L in non-diabetic group 2,and there were significant differences between two groups (P ＜ 0.05).The correlation analysis showed that VEGF was positively correlated with MPO in diabetic group 1 and diabetic group 2 (r =0.632 and 0.763,P ＜ 0.05),and VEGF was positively correlated with MPO in non-diabetic group 1 and non-diabetic group 2 (r =0.610 and 0.713,P ＜ 0.05).Conclusions Compared with those in non-diabetic MHD patients,VEGF and MPO levels are significandy higher in diabetic MHD patients.In non-diabetic MHD patients and diabetic MHD patients,VEGF and MPO levels will rise gradually with duration of hemodialysis.The expressions of VEGF and MPO are associated with each other.
