Chinese Journal of Nosocomiology 1994;0(01):-
OBJECTIVE To investigate the infectivity and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh),and instruct reasonable application of antibiotics clinically.METHODS Mycoplasma IST kit was used to detect Uu and Mh and their drug resistance.RESULTS The prevalence of Mycoplasma in males was 44.7%,in females was 46.0%.The resistance rate of Uu to ciprofloxacin,ofloxacin and(erythromycin) was(85.1%),47.1%,and 24.8%;the resistance rate of Mh to ciprofloxacin,ofloxacin and(erythromycin) was 76.9%,54.2%,and 54.2%,respectively.The sensitive rate of Uu to doxycycline,(pristinamycin) and josamycin was 95.5%,95.5%,and 91.3%;the sensitive rate of Mh to doxycycline,(pristinamycin) and josamycin was 95.8%,95.8%,and 91.7%,respectively.CONCLUSIONS To deal with the(infection) of Uu and Mh,the antibiotics such as doxycycline,josamycin and(others) which are sensitive to such strains can be used.Uu and Mh have a high(resistance) rate to quinolones,which should be paid high clinical(attention).

Objective To explore the clinical outcome of free chimeric anterolateral thigh cutaneotendinous flap with rectus femoris muscular flap for repairing the complex tissue defect of dorsum wrist. Methods From June, 2005 to March, 2014, free chimeric anterolateral thigh cutaneotendinous flap with rectus femoris muscular flap was used for repairing the complex tissue defect of dorsum wrist in 15 cases, which were 12 males and 3 females, and aged from 18 to 52 years old. The skin and soft tissue defect ranged from 8.0 cm×5.5 cm to 22.0 cm×12.0 cm. All ac-companied with extensor digitorum tendon loss. The tendon defect ranged from 5.0 cm to 12.0 cm (7.6 cm on average). The flap size ranged from 9.0 cm×6.5 cm to 23.0 cm×13.0 cm. The pedicle length ranged from 4.0 cm to 7.0 cm (5.3 cm on average). Results All flaps survived, and no postoperative complications occurred. The followed-up time ranged from 12 months to 36 months, and the texture of flap was flexible. No bulky was noted, and skin color was similar to the hand skin. The flexor and extensor function of wrist recovered satisfying. The 2-point discrimination of flap ranged from 9 mm to 15 mm (12.5 mm on average). Conclusion Free chimeric anterolateral thigh cutaneo-tendinous flap with rectus femoris muscular flap is a good option for repairing the complex tissue defect of dorsum wrist.

Objective To investigate the efficacy and safety of Shuo Tong ureteroscopy in the treatment of upper ureteric stones.Methods The data of 832 patients,who underwent Shuo Tong ureteroscopy combined with holmium laser for the treatment of upper ureteric stones were collected between July 2014 and February 2017.The patients accepted general anesthesia under lithotomy position.After dilating the ureter,a ureteral access sheath was inserted along the guide wire.Finally,stones were broken and clean up by Shuo Tong ureteroscope.According to the stone size,823 patients were divided into ≤2.0 cm group (n=112,13.6%),2.1-3.0 cm group (n =395,48.0%),3.1-4.0 cm group (n =257,31.2%),> 4.0 cm group (n =59,7.2%)The stone free rate(SFR) and post-operative complications were observed.Results Among 983 operations,663 cases accepted one-stage operations and 160 cases accepted second stage operations.the operative time and postoperative hospital stay were 23-145 min(mean 74.8 ± 35.3) and 1-5 days(mean 1.9 ±0.8),respectively.The SFR in the first day and one month after operation was 75.6% and 83.8%,respectively.The stone free rate in each group were 89.3%,82.5%,61.1%,52.5% at first day after operation respectively(P < 0.05).While,the SFR after one month were 95.5%,87.6%,72.0%,61.0% in each group,respectively(P < 0.05).Fever rate after operation was 11.1%,ureteral injury rate was 1.9%,severe hematuria rate was 0.6%,stone street formation rate was 1.2%,perirenal hematoma rate was 0.4%.All patients were improved after conventional treatment.Conclusion Shuo Tong ureteroscopy is a safe treatment with high stone free rate for upper ureteric stones.

Objective:To explore the clinical effect of R-MAD (rituximab, methotrexate, cytarabine, dexamethasone) regimen in the treatment of primary ocular adnexal double-expression diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of an elderly patient with primary ocular adnexal double-expression DLBCL who was treated with R-MAD regimen in June 2019 in Fujian Medical University Union Hospital was retrospectively analyzed. The clinical manifestations, diagnosis and treatment, prognosis were also analyzed, and the related literature was reviewed.Results:The patients was a 71-year-old male. After initial treatment of R-CHOP chemotherapy, the patient's eye mass did not shrink, the swelling and pain became worse, the curative effect was not good, and the disease progression continued. After the patient was given R-MAD chemotherapy for 3 courses, the eye swelling subsided and pain symptoms were significantly improved, satisfactory results were obtained, and no obvious adverse reactions occurred.Conclusions:R-MAD regimen has an ideal effect on the patient with primary ocular adnexal double-expression DLBCL, which can significantly improve symptoms, delay disease progression, and improve the quality of life of patients, but the prognosis still needs to be followed up in the long-term.

Virtual reality technology is a technology that creates a visual environment for people to experience through computer simulation, with features of immersion, interaction and imagination. This technology was used in engineering mechanics and urban planning in early times In medicine, diagnostics serves as a bridge for medical students to transit from basic medicine to clinical medicine. Using virtual reality technology to produce standardized patients (SPs) allows medical students to simulate the role of clinicians in the classroom, complete the diagnosis and treatment for virtual patients using various electronic media and the mastered theoretical knowledge of diagnostics, set up simulation training and online-and-offline teaching according to the diagnostic course standards which compensates the disadvantages in traditional medical teaching. Virtual reality technology has practical significances for cultivating medical students' clinical skills and thinking through procedural process evaluation, real-time feedback, etc.. This paper will discuss the prospect of virtual reality technology, its application as well as its advantages in diagnostic teaching.
