Objective To explore the value of asthma journal and corresponding monitoring of pulmonary ventilation function in treating bronchial asthma with the existing classification of asthma severity as control.Methods After 137 patients with bronchial asthma were evaluated according to the existing grades,they kept asthma diaries and received corresponding monitoring of pulmonary ventilation function at least 5 times per day,and all of the above clinical data were analyzed by relevant statistical methods.Results Among the 126 patients who completed monitoring,only 61(48.41%) patients could be graded by the Guide for Prevention and Treatment of Bronchial Asthma;27(21.43%) patients felt sensitive while 33(26.19%) ones felt insensitive.Conclusion The corresponding monitoring can not only accurately evaluate the severity of patients' bronchial asthma condition,but also detect those patients with deviated symptom perception.

Objective To evaluate the efficacy of the intensity modulated radiotherapy in early stage cervical cancer with vaginal stump recurrence after surgery.Methods A retrospective concurrent comparative study included 60 patients with vaginal recurrence after surgery in early stage cervical cancer.30 cases of the experimental group were treated with intensity-modulated radiotherapy (IMRT),and 30 cases of the control group were treated with conventional radiotherapy.The efficacy and complications between two groups were compared after 3 treatment cycles.Results Of 30 patients in experimental group,22 patients achieved complete remission,7 had partial and 1 progressed.But in the control group,14 had complete remission,5 reached partial remission,7 were stable and 4 progressed.The effective rates were 96.67 ％ (29/30) and 63.33 ％ (19/30),respectively,in the experimental and control group,which showed statistical significance (P =0.009).In the experimental group,there were 1 case with grade 1 radiation cystitis and 1 case with grade 1 radiation proctitis.In the control group,there were 3 cases of vaginal-rectal fistula,1 case of grade 3 radiation proctitis,2 cases of grade 2 radiation cystitis and 2 cases of grade 1 radiation proctitis.Conclusions IMRT for treating vaginal recurrence of early cervical cancer achieves satisfactory short-term effect.In comparison with conventional radiotherapy,IMRT has higher efficacy but less side effects.

Objective To compare the dose distribution of mantle-field radiotherapy using conven-tional radiotherapy(CRT) and four intensity-modulated radiotherapy(IMRT) techniques in stage Ⅰ and Ⅱ Hodgkin's lymphoma(HL). Methods Ten patients with patholocally proved early stage HL underwent CT simulation. Then both CRT and IMRT planning performed using ECLIPS treatment planning system(TPS). The dosimetric parameters of different irradiation plans were analyzed, including conformal index (CI), homo-geneity index (HI), D95 and V95 of planning target volume (PTV), Dmax,Dmean,Dmin,V5,V10,V20 and V30 of the lung, as well as Dmax of the spinal cord. Results The isodose distribution and homogeneity of PTV were better in IMRT plans when compared with CRT plans. Target coverage, target dose conformity and homogene-ity were similar among all the four IMRT techniques. The V30 of the lung using IMRT was lower than using CRT,but the low-dose volume of the lung was higher. Among the four IMRT technique plans,the lung V20 and V30 were lower in plans with more-field technique,but the V5 and V10 were higher. The Dmax of the spinal cord using IMRT was all lower than that using CRT. Conclusions IMRT is better than CRT in target cov-erage, conformity, homogeneity and normal tissue sparing, especially in protecting the spinal cord and decrea-sing high-dose lung volume,though the low-dose lung volume is higher. Seven-field IMRT technique for man-de-field radiotherapy is recommanded.

OBJECTIVE: To determine the vaginal flora distribution in cervical cancer patients and the common pathogenic bacteria as well as drug resistance, and to explore the correlation of vaginal bacterial infection and high-risk human papillomavirus (HR-HPV) infection with cervical cancer.
 METHODS: A total of 216 patients with cervical cancer served as an experimental group, and 53 patients with chronic cervicitis served as a control group. The patients' vaginal fluid in two groups was collected before the treatment for regular bacterial culture and HPV testing. The distribution and drug resistance of bacteria in two groups of vaginal secretion were observed, and the correlation of the bacterial infection and HPV infection with the cervical cancer was analyzed.
 RESULTS: The gram-negative and gram-positive bacteria accounted for 74.38% and 21.49% in the experimental group, respectively. They were mainly resistant to ampicillin and piperacillin or penicillin and erythromycin. The gram-negative and gram-positive bacteria accounted for 42.31% and 23.08% in the control group, respectively. They were mainly resistant to ampicillin and piperacillin or penicillin. HPV-positive rates in the experiment group and the control group were 60.65% and 41.51%, respectively. There were 70 patients (32.41%) and 12 patients (22.64%) with both bacterial infection and HPV-positive infection in the experiment group and the control group, respectively. However, there was no statistical difference between the 2 groups (P>0.05). 
 CONCLUSION Escherichia coli are the main pathogen in cervical cancer and they are highly resistant to antibiotics. Bacterial infection in genital tract is not an efficient cofactor for HPV to cause the cervical cancer.
