OBJECTIVE To investigate present conditions about the fungal infection and analyze its risk factors and the measure of prevention. METHODS Before statistics and analysis,clinical data and culture results of 175 cases from Jan 2002 to Dec 2004 were collected. RESULTS The respiratory tract occupied the majority of the fungus infection(40.00%),the gastrointestinal tract was the second(23.43%),and the urinary tract was the third(19.43%).In infection strains,Candida albicans occupied the first place(68.57%),C.tropicalis and(C.glabrata) were the second and third(6.86% and 5.71%). CONCLUSIONS The fungal infection is relevant to some risk factors,such as using antibiotics,underlying disease and aging.Therefore,using antibiotics reasonably and improving the immunity of organism are the main measures of preventing the fungal infection.

Objective To analyze the causative of damaged bioprosthetic valves implanted in 41 patients (with total 47 valves) over one year. Methods From June 1993 to June 2004,re-replacement of valves was performed in 41 patients with dysfunctional bioprosthetic valves. The interval between the two operations was 1～16 years [mean (9.7?4.1) years]. The 47 dysfunctional bioprosthetic valves were carefully observed and pathologically examined. Results Of the 47 valves, no valve frame was damaged; tear or perforation existed in 42 valves (89.3%); calcification was found in 35 valves (74.5%), with fibrosis; excrescence and thrombus coexisted in 2. Heavily damaged ones were sent for pathological examination, and infiltration of abundant phagocytes and monocytes was found. Conclusion Early damages were mainly tear or rupture, while late damages were compound outcomes of multiple damaging factors such as calcification, rupture, and tear.

Objective To investigate the clinical features,treatment,prognosis,and occurrence of neurogenic pulmonary edema(NPE) in children with severe hand-foot-mouth disease (HFMD) complicated with brain stem encephalitis and abnormal cranial magnetic resonance imaging (MRI).Methods 386 cases of severe HFMD were hospitalized in our Intensive Care Unit (ICU) from May to October 2010,of which 24 cases had abnormal cranial MRI.Their clinical symptoms,MRI features,treatment,and prognosis were analyzed.Results The clinical symptoms of severe HFMD with brainstem encephalitis included fever,startle,lethargy,vomiting,difficulty swallowing,drooling,and so on.The patients with abnormal cranial MRI were prone to have a neurogenic pulmonary edema (NPE) (5％ vs 6.5％,x2 =34.55,P ＜0.01).Conclusions The nervous system-affected parts of severe HFMD is the brain stem,thalamus,and spinal cord.Brain stem inflammation can be found early by the cranial MRI to be highly vigilant of NPE.During course of 1 ～ 5 day,special attention should be paid to the symptoms of the nervous system.The early detection,timely intervention,and prevention from NPE would result in the good prognosis.

BACKGROUND:Intraarticular cocktail analgesic injection is a popular postoperative analgesia method and can effectively control postoperative pain and relieve side effects after total hip arthroplasty.
OBJECTIVE:To compare and assess the effectiveness and safety of intraarticular analgesic injection or intravenous injection of parecoxib after total hip arthroplasty.
METHODS:A total of 60 patients undergoing total hip arthroplasty were randomly assigned to:treatment group (intraarticular cocktail analgesic injection with morphine, bupivacaine, and compound betamethasone), and control group (intravenous injection of parecoxib). Al patients received tramadol hydrochloride at 24 hours after replacement. Analgesic consumption, visual analog scale at rest and during activity, range of motion, and postoperative complication of patients in each group were recorded.
RESULTS AND CONCLUSION:Intraarticular cocktail analgesic injection significantly reduced analgesic consumption. When comparing visual analog scale scores, rest pain scores were significantly less in the treatment group at 12, 24 and 48 hours after replacement than that in the control group (P<0.05). Scores on range of motion were significantly less in the treatment group at 24 and 36 hours than that in the control group (P<0.05). No significant differences in total complications were detectable between the treatment and control groups (P>0.05). Results suggested that intraarticular cocktail analgesic injection lessened analgesic consumption after replacement, relieved early pain after replacement, and contributed to early rehabilitation of patients. Moreover, no significant adverse reactions were visible.

Objective To investigate the efficacy of medical therapy after conservative operation for endometriosis.(Methods)Endometriosis was confirmed in 89 patients by laparoscopic inspection,and conservative operations were performed to remove the adhesion,excise or destroy all the endometriotic tissues,including single excision of endo-(metriotic) masses or plus unilateral salpingoophorectomy,and to restore pelvic anatomy to the best possible condition.All the patients were divided into two groups randomly: treatment group(n=44),three months drug therapy of go-(nadotropin-)releasing hormone analogs(GnRHa) after operation;control group(n=45),no drug therapy after operation.Clinical symptoms,concentrations of CA-125,manual and ultrasonic pelvic check-up,as well as pregnancy rate to those who had a desire for future fertility(n=28)were followed up. Results All the patients experienced alleviation of clinical symptoms after the operation.The recurring rates: 0% in treatment group vs 4% in control group six months later;2% in treatment group vs 4% in control group 12 months later(P

Urinary tract infection complicated with urinary tract calculi( lithangiuria)is one of the most common diseases causing serious urinary sepsis and septic shock. Recent studies show that the accurate diagnosis,rational use of antibiotics and timely treatment of complications are the key to treatment success. In this article,the latest progress and the treatment strategies for urinary tract infections complicated with lithangiuria are explored.

To modify the splicing pattern of Bcl-x and compare the effect of this approach with that of the antisense gene therapy in BIU-87 cell line of bladder cancer, by using 5'-Bcl-x AS to target downstream alternative 5'-Bcl-x splice site to shift splicing from Bcl-xL to Bcl-xS and 3'-Bcl-x AS antisense to the 3'-splice site of exon III in Bcl-x pre-mRNA to down regulation of Bcl-xL expression, the inhibitory effects on cancer cells by modification of alternative splicing and antisense gene therapy were observed and compared by microscopy, MTT Assay, RT-PCR, FACS, Westhern bloting and clone formation. The growth of cells BIU-87 was inhibited in a dose- and time-dependent manner. Its inhibitory effect began 12 h after the exposure, reaching a maximum value after 72h. The number of cells decreased in S phase and the number increased in G1 phase. The ability to form foci was reduced and the antisense gene therapy was approximately half as efficient as modification of alternative splicing in inducing apoptosis. It is concluded that modification of splicing pattern of Bcl-x pre-mRNA in bladder cancer cell BIU-87 is better than antisense gene therapy in terms of tumor inhibition.
