Symptom clusters changes in patients with lung cancer during treatment / 中国实用护理杂志

Objective To explore symptom clusters and changes with time goes among inpatients of lung cancer to provide the basis for clinical nursing staff on symptom management. Methods Using the Chinese version of the M.D. Anderson Symptom Inventory (MDASI-C) and the revised lung cancer module on 217 cases of inpatients with lung cancer, and the follow-up after 1 month, 3 months by telephone. Results The result of principal component analysis of three times:there are same symptom clusters on three times evaluation, fatigue-related symptom cluster, lung cancer specific symptom cluster, chemotherapy-related symptom cluster and psychological symptom cluster. The first and third time assessment also contains respiratory symptom cluster. Over time some kinds of symptom clusters company with the disease trajectories. Fatigue-related symptom cluster is the major cluster and correlate to psychological and other symptom clusters. Conclusions Clinical workers should perfect the symptom management of patients all the time according to severity and changes of symptom clusters to benefit patients with lung cancer.

The application of anti-reflux indwelling needle after gastrointestinal polyps resection / 中国实用护理杂志

Objective To discuss the effect of the application of anti-reflux venous indwelling needle after gastrointestinal polyps endoscopic resection.Methods 400 cases of patients after gastrointestinal polyps endoscopic resection were selected in our department.200 cases of patients using ordinary venous indwelling needle were set as the control group.In addition,200 cases of patients chose anti-reflux indwelling needles which were produced by a certain medical instrument Co.,Ltd were set as the experimental group.The incidence rate of phlebitis,tube blocking,blood return and indwelling time in the process of using anti-reflux indwelling needle were observed in two groups.Results During the indwelling time of two kinds of indwelling needles,the incidence rates of phlebitis,tube blocking and blood return of anti-reflux indwelling needle in the experimental group were significantly lower than those of the control group.The average indwelling time of the experimental group was 1.2 days,longer than that of the control group.Conclusions Anti-reflux indwelling needle can effectively protect the blood vessels,ensure the patients to use drugs in time,improve the work efficiency of nurses,reduce the damage to patients and effectively reduce the burden of patients.

Detection of E2 gene polymorphism of human papillomavirus type 16 in patients with cervical lesions and cervical cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the incidence of human papillomavirus type 16 (HPV16) infection in patients with cervical diseases and analyze E2 gene mutations and its correlation with cervical lesions.</p><p><b>METHODS</b>Specific primers were designed according to the full-length E2 gene sequence of HPV16 from the GenBank. PCR was used to analyze the incidence of HPV16 infection in the exfoliated cell samples from 379 patients with different cervical diseases positive for high-risk HPV. The polymorphisms of E2 gene of HPV16 were analyzed by high-resolution melting.</p><p><b>RESULTS</b>Of the 379 exfoliated cell samples from the cervix, 78 were positive for HPV16 infection. The positivity rates of HPV16 infection was 44.8% in patients with cervical cancer, 31.5% in patients with CIN II-III, 24.1% in patients with CIN I and 9.6% in patients with cervical inflammation. The frequencies of E2 gene 68C and 133G variations were significantly higher in patients with CIN II-III and those with cervical cancer than in those with CIN I and those with cervical inflammation (P<0.05).</p><p><b>CONCLUSIONS</b>HPV16 is an important cause of cervical cancer, and HPV16 infection rate increases with the pathological progression of the cervical lesions. The naturally occurring sequence variations of HPV16 E2 gene may cause alterations of the carcinogenic potential of the virus.</p>

A clinical and etiological analysis of candida urinary tract infections in intensive care unit / 中国医师进修杂志

Objective To investigate the clinical characteristics, risk factors and pathogenic disposition of candida urinary tract infections in intensive care unit(ICU)patients. Methods A retrospective review and analysis of clinical information and urine culture of 83 ICU patients with the candida urinary tract infections. Results All patients had severe underlying diseases one or more complication and/or concomitant diseases were existed at the same time. All of the patients previously used broad-spectrum antibiotics and received invasion in diagnosis and therapy: indwelling urinary catheters, mechanical ventilation, incision of trachea, deep artery or vein operation with catheters indwelling, surgical operation and indwelling drainage tube (96.39%, 95.18%, 69.89%, 46.99%, 43.37%, 33.73%, respectively). In all the patients, 62.65% patients were elder. Hospitalization days of 54.22% patients staying in ICU were above 31 days. Mortality rate was in 39.76%( 33 cases ). C.tropicalis(55.91%) and C.albicans(35.48%) were the major pathogens. Seventy-four cases( 89.16%)were infected by one candida specie, and 9 cases( 10.84% )were infected by two or three candida species. The positive blood culture was found in 9 cases ( 10.84% ) also. Conclusions The ICU patients with severe underlying diseases and high risk factors may have candida urinary tract infections easily. C.tropicalis and C.albicans are the most common pathogens. Some candiduria is the evidence of candidemia.
