Objective To analyze the infection control of chronic osteomyelitis with antibiotic bone cement. Methods In our hospital, 50 patients were randomly divided into study group and control group,after clearing the focus,patients were given antibiotic bone cement and closed lavage and drainage respectively. The hospitalization time,average number of operation and the cure rate of patients were observed. Results The average hospitalization time of 21 patients in the study group was ( 65 ± 4. 2 ) d;the mean number of operation was (2. 3 ± 1. 2);the cure rate was 85. 7%. The average duration of hospitalization of 29 patients in control group was (103 ± 2. 5) d;the mean number of operation was (2. 8 ± 1. 4);the cure rate was 55. 2%. The difference between the 2 groups was statistically significant (P<0. 05). Conclusion Antibiotic bone cement has a good therapeutic effect in the treatment of patients with chronic osteomyelitis,which reduces the hospitalization time and the number of operation,improves the cure rate of patients,focal infection after the removal is controlled well.

Objective To discuss the role of traditional Chinese medicine in community health education of diabetic nephropathy (DN). Methods 124 patients of DN were randomly recruited into an observation group and a control group, with 62 patients in each group. The patients in the observation group participated in TCM health care education voluntarily, while the patients in the control group did not take any TCM education health care. Questionnaires were used to investigate relative knowledge to DN and demands and suggestions to TCM education health care. Results Patients in the observation groups had an obviously better understanding to DN knowledge than before. The therapeutic effects in the observation group were significantly better than the control group (λ2=3.376, P<0.01). Conclusion The application of TCM health education in community DN patients will effectively enhance the cognition of the patients to DN, and will also promote the therapeutic effects of DN treatment outside hospital.

Objective To explore the clinical curative effect and complications of digital three-dimensional molding of titanium mesh for repairing skull defect. Methods The clinical data of 42 patients having underwent repairing skull defect with three-dimensional molding of titanium mesh were retrospectively analyzed. Results The average operation time was about 2 h, and 42 patients were operated successfully. The bilateral skull was symmetry and the appearance was good. In 42 patients, subcutaneous dropsy occurred in 1 case, epilepsy occurred in 3 cases, and intracranial bleeding again surgery occurred in 1 case. Patients were satisfied with the results of cranioplasty. Conclusions Repairing skull with digital three-dimensional molding of titanium mesh is simple, with shorter operation time, lower operation risk, and lower postoperative complication, and the clinical curative effect is satisfactory.

Objective: This study aimed to translate the English version of the Perceived Competence Scale for Disaster Mental Health Workforce (PCS-DMHW) into Chinese, and to test its reliability and validity in Chinese mental health workers. Methods: With the consent of Professor Choi, Keimyung University, Korea, and the authorization of the scale, the English version of PCS-DMHW was translated, retranslated and culturally debugged to form the Chinese version of PCS-DMHW. The general information questionnaire and the Chinese version of PCS-DMHW scale were used to investigate 706 mental health workforce from 9 tertiary hospitals in Sichuan province in China from March 24, 2020 to April 14, 2020. The Cronbach’s α coefficient was used to evaluate the internal consistency reliability of the scale, and the test-retest correlation coefficient r was used to evaluate the test-retest reliability of the scale. The content validity indexes (CVI) and exploratory factor analysis (EFA) was used separately for evaluating the content validity and structure validity of the scale. Results: The Cronbach’s α coefficient of the Chinese version of PCS-DMHW total scale, individual competences and organizational competences subscale was 0.978, 0.956, and 0.964, respectively. The test-retest reliability of the total scale, individual competences and organizational competences subscale was 0.949, 0.932 and 0.927, respectively. The item-level CVI of all scale were ranged from 0.833–1.000, the scale-level CVI (S-CVI)/universal agreement of the total scale, individual competences and organizational competences subscale was 0.833, 0.875, and 0.857, respectively, and the S-CVI/average was 0.972, 0.979, and 0.976, respectively. EFA showed that two principal components were extracted from the subscale of individual competences and organizational competences. Conclusion The Chinese version of PCS-DMHW has good reliability and validity, and can be widely used in China.

Objective To discuss the feasibility and the curative effect of transurethral diverticulum section in the treatment of female urethral diverticulum.Method We retrospectively analyzed the transurethral diverticulum section surgeries of 11 adult female patients diagnosed as urethral diverticulum in our hospital from August 2012 to October 2016.The patients aged from 33 years old to 74 years old with an average age of 43.Their medical histories varied from 1 month to more than 40 years with an average histories of 80 months.Major symptoms included odynuria,frequent micturition,dyspareunia,perineum bearing-down feeling,repetitive urinary tract infection,dysuria,urinary stuttering,penis masses,etc.One patient underwent TVT-O.Two patients had urinary catheterization before the disease.During physical examination,cystic masses of different sizes could be touched on anterior vaginal walls with pain and secretion.Cystic lesions can be found by imaging examination.Transurethral diverticulum section was performed under general anesthesia.Using needle electrode by resectoscope,we made an annular incision in the direction of the vertical axis of the urethra,from the beginning of diverticulum ostium.The diverticulum completely communicated with the urethra.In 11 patients of transurethral endoscopic,the urethral sphincter and the diverticulum wall appeared morphological integrity and no damage.There was no liquid drained to de vagina.There was no urethral sphincter injury and no urethral vaginal leakage.We observed the operation time,bleeding volume,diverticulum position,the number of diverticulum,urethral sphincter intraoperative.We also observed the postoperative symptoms,short-term and long-term complications.Result All surgeries went on well,in which urethral diverticula were fully opened.The operation time was 30-45 minutes,average 35 minutes.The amount of bleeding within 5 ml.4 cases with multiple diverticulum,with 2 cases of diverticulum ostia were 2,2 cases of diverticulum ostia were 3.The other 7 cases with single diverticulum,diverticulum ostium was 1.The catheters were removed 2 weeks after the surgery,after that all patients can urinate normally.The follow-up time was 5-55 months (mean,24 months).All pre-surgical symptoms disappeared and no complication occurred,such as urethral stricture,urinary incontinence,urethro-vaginal fistula,etc.Conclusion Transurethral diverticulum section is a reliable treatment for female urethral diverticulum with positive curative effect and no obvious complication.
