Objective To explore a potentially effective treatment of postoperative deep infection after spinal instrumentation without removal of implants. Methods A total of 4 patients with postoperative deep infection after spinal instrumentation were treated at our hospital between January 2015 and May 2016. They were 2 men and 2 women, aged from 62 to 75 years (mean, 69.2 years). They were treated with ag-gressive surgical debridement under the guidance of methylene blue and negative pressure wound therapy. Reversed latissimus dorsi muscle flap was used to obturate the wound when the bacterial culture of the wound was negative and the relevant inflammatory indicators returned to normal. Negative pressure treatment con-tinued over the closed incision. Results The devices for negative pressure wound therapy were removed in the 4 patients one week after surgery. All the wounds were healed well by first intention 2 weeks after surgery without removal of their implants. The patients were discharged after their examinations for blood routine, CRP, ESR and PCT turned to be normal. Follow-ups for more than one year revealed no re-infection, implants loosening or other adverse effects. Conclusions Negative pressure wound therapy combined with reversed latissimus dorsi muscle flap is a new attempt to treat postoperative deep infection after spinal instru-mentation without implant removal. It may increase the rate of implants reserved, accelerate wound healing and raise the curative rate of deep infection.

Objective To assess the income status of primary care providers and to explore the determinants of income in a county of Dali. Methods In August 2016, the questionnaire was employed to collect the data of income status of 191 rural health workers and 217 village doctors in the county. Results Through the study, we found that the income of rural health workers in the county was 34, 000 (26, 000, 46,000) yuan with a satisfaction rate of 62.3% (95% CI 55.4%～69.2%) and no change (74.7%) was seen in the income among majorities after implementing the Zero Mark-up Policy for essential medicines. For the village doctors, the income was 20,000 (15,000, 24,000) yuan with a satisfaction rate of 40.6% (95% CI 34.0%～47.1%) and a fall of the income was found in more than half of the doctors after the implement of the policy. Conclusion Health care workers in towns are quite satisfied with their income whereas those in health stations of villages are not content, compared with the average income at the national level. We should increase government's investments on grass-root healthcare team, improve the incentive pay plans and promote the integrated management of health facilities in towns and villages.

By using rice SSRP, RAPD and AFLP molecular markers, the genome of rice transgenic line "Minghui 63-Xa21" was analyzed. 32 SSRP primers, 42 RAPD primers and 8 AFLP primers could produce obvious PCR bands in the analysis of at least 12 individual plants selected randomly from "Minghui 63-Xa21" T3 generation. Totally 550 PCR bands, equivalent to 550 genomic sites, were detected. Different individual plants of the transgenic homozygous line displayed almost the same PCR pattern. Compared with the control "Minghui 63", no difference was found in their PCR patterns. This indicated that the introduction of Xa21 into the genome of "Minghui 63" did not change these 550 genome sites and their heredity. Very few variant PCR bands were observed in some individual plants from both "Minghui 63-Xa21" and "Minghui 63". However, the variant percentage was equivalent between the transgenic line and the non-transgenic control line.

OBJECTIVETo explore the diagnosis, treatment, and prognosis of prostatic malignant mesenchymal tumors (PMMT).

METHODSWe retrospectively analyzed the clinical and follow-up data about 20 cases of PMMT and reviewed the literature relevant to the diagnosis, treatment, and prognosis of the disease.

RESULTSBased on the results of pathology and immunohistochemistry, the 20 PMMT cases included leiomyosarcoma (n = 7), rhabdomyosarcoma (n = 5), prostatic stromal sarcoma (n = 3), chondrosarcoma (n = 1), and undifferentiated PMMT (n = 4). Twelve of the patients were treated by radical prostatectomy (3 concurrently by sigmoid colostomy and 1 by cystostomy), 2 by pelvic tumor resection following arterial embolization, 1 by total pelvic exenteration, 1 by colostomy with pelvic lymph node biopsy, and 4 by conservative therapy because of metastasis to the lung, pelvis and bone. Of the 20 patients, 9 died of systemic metastasis within 3 months after treatment, 3 died at 6, 7, and 14 months, respectively, 3 survived with tumor for 5, 11, and 12 months, respectively, 2 survived without tumor for 12 and 24 months so far, all subjected to periodic chemotherapy postoperatively, and 3 lost to follow-up.

CONCLUSIONPMMT is a tumor of high malignancy and rapid progression, for which transrectal ultrasound-guided biopsy remains the main diagnostic method. The clinical stage of the tumor is an important factor influencing its prognosis and the survival rate of the patients can be improved by early diagnosis and combined therapy dominated by radical prostatectomy.

In order to analyze the clinical features and laboratory findings in patients with acquired hemophilia A, one case of acquired hemophilia A was studied, the medical history, clinical features, ultrasonography and laboratory examination including activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and FVIII:C, FIX:C, FXI:C, FXII:C ratio, as well as medical treatment were analyzed. The results showed 99.3 sec of APTT, 13 sec of PT, and 13.5 sec of TT, 2% of FVIII:C, 7% of FIX:C, 9% of FXI:C and 21% of FXII:C. The prolongation of APTT could not be completely corrected by mixing the patient plasma with an equal volume of normal fresh plasma; the APTT increased with prolongation of incubation time, when patient plasma was mixed with an equal volume of normal fresh plasma and incubated at 37 degrees C. The plasma FVIII:C, FIX:C, FXI:C and FXII:C levels in patient were 6%, 75%, 95% and 123% respectively, when patient's plasma was diluted by tenfold and mixed with an equal volume of non-diluted normal plasma. FVIII inhibitor in the patient's serum was at a level >32.0 Bethesda units/ml after acquired hemophilia was diagnosed, the patient was admitted to hospital and given orally prednisone and azathioprine therapy. One month later, clinical status of the patient were improved with 33.3 seconds of APTT, 128% of FVIII level and elimination of FVIII inhibitor. In conclusion, inquiring case history, analyzing imaging results, detecting level of APTT, performing dilution test and assaying titer of FVIII inhibitor can reduce misdiagnosis and wrong therapy for patients with acquired hemophilia A. The FVIII inhibitor can be eliminated and function of clotting can be recovered by using immunosuppressive therapy.
