BACKGROUND: The study aimed to investigate the clinical characteristics of acute renal failure (ARF) caused by oral acyclovir. METHODS: A 45-year-old Chinese male patient with acyclovir-induced ARF suffered from abdominal pain for one day. The pain was extended to the epigastric area from the right lower quadrant. Transient oliguria was seen in addition to microscopic hematuria and proteinuria. The serum creatinine concentration was 304 μmol/L. Eight days before the occurrence of ARF, the patient took oral acyclovir for facial neuritis. RESULTS: His renal function was restored completely following the discontinuation of acyclovir, with continuous renal replacement therapy for 54 hours and some symptomatic treatment. CONCLUSION: The presentation of acute renal failure caused by acyclovir can be diverse, but the prognosis is good after active treatment.

AIM: To investigate the incidence of trachoma in children aged 1 to 9y in Hainan Province and determine high-risk trachoma endemic and non-endemic areas in Hainan, and thus provide evidence for developing trachoma control and prevention therapy.METHODS:The areas of investigation were chosen on the basis of past literatures, expert interviews and survey on the spot.In 2013, Hainan Provincial Office of Blindness Prevention carried out the survey in 7 counties including Dongfang City, Wuzhishan City, Ledong County, Baisha County, Baoting County, Lingao County and Changjiang County.In these districts, 356 pupils including 192 boys and 164 girls were examined, their age ranging from 1 to 9 and their average age being 7 years old.The targeted students received the trachoma rapid assessment by the adoption of simplified trachoma classification system which was recommended by the World Health Organization.RESULTS: No case of active trachoma was found among the 356 students.CONCLUSION:The prevalence rate of trachoma in children under 9 years is less than 5% in Hainan Province.Active trachoma is not a public health issue in Hainan Province.

Objective To explore the imaging features and dynamic CT findings of primary adrenocortical carcinoma and evaluating its clinical value.Methods All 11 cases patients with primary adrenocortical carcinoma confirmed by surgical pathology underwent spiral CT plain scanning and two phases dynamic enhancement scanning before operation.Contrast injection was done by using nonionic Omnipaque at a flow rate of 3 ml/s with a power injector.The CT images were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Five of 11 lesions were located in the right adrenal gland,6 in the left.The diameter of the tumors was 4.1—16.0cm with 2 cases10.0cm.The attenuation of the plain scans,two phases contrast scans was 21.9—46.7 HU(with a mean value of 35.3 HU),30.5—65.8 HU(mean value 47.1 HU),and 52.6— 97.0 HU(mean value 74.2 HU),respectively.Four were in the shape of capsule,6 reticular,1 slightly inhomogeneous masses.The irregular tumor vessels of 6 reticular masses were seen in the artery phase. Conclusion The dynamic CT features of primary adrenocortical carcinoma were obvious,dynamic SCT scans could suggest the diagnose.

Objective To explore the efficacy and safety of autologous peripheral blood stem cell transplantation (APBSCT) in the treatment of systemic lupus erythematosus.Methods Nine patients with systemic lupus erythematosus were enrolled in this study.Patients were given cyclophosphamide and granu- locyte colony-stimulating factor(G-CSF)as the mobilization regimen.Urine was alkalinized and hydrolyzed to protect the function of the heart,liver and kidney of the patients.A CS3000 Plus blood cell separator was used to collect peripheral blood stem cells,which were preserved in liquid nitrogen.Two to five days before the administration of the stem cells,the patients were pretreated with intravenous injection of cyclophos- phamide (50 mg?kg~(-1)?day~1) for 4 consecutive days and antithymocyte globulin (ATG,2.5 mg?kg~(-1)?day~1) for 3 consecutive days.Granulocytes were recoverd by G-CSF stimulation.Then,the peripheral blood stem cells were reinfused.Therapeutic effect was evaluated by assessment of alteration of clinical manifestation (skin erythema),levels of proteinuria and antoantibodies,hematopoietic reconstitution and occurrence of transplantation related complications.Results After transplantation,all patients had been successfully en- grafted.The time for peripheral leucocyte count to reach 1.0?10~9/L was 7～15d;the time for platelets to reach 20?10~9/L was 0～21 d.The skin erythema resolved in all patients;proteinuria decreased to normal level and the autoantibodies became negative in most of the patients.Serum sickness-like response occurred in all patients,renal and heart failure in 1 patient,hemorrhagic cystitis in 3 patients,psychiatric disorders in 1 patient,candidal infection in 1 patient.Conclusion One-year follow up suggests that autologous stem cell transplantation is markedly effective and relatively safe for systemic lupus erythematosus.However,the duration of remission remains to be investigated in a long-term follow up study.

OBJECTIVETo study the correlation between Vibrio cholerae strains isolated from natural enviroment and fishery products and the source of infection during V. cholerae outbreaks.

METHODSCholera toxin gene was detected by polymerase chain reaction (PCR) amplification. Pulsed-field gel electrophoresis (PFGE) was used to subtype the isolates. Results of PFGE were analyzed and clustered by BioNumerics software (Version 4.0).

RESULTSDuring the outbreaks, a total number of thirty O139 V. cholerae related serogroups were collected from patients, carriers, sewage and fishery products were identified and proved to be toxigenic. They could be clustered into four PFGE patterns when digested by Not I. These two V. cholerae outbreaks were caused by the same source of infection because of the following reasons: (1) PFGE patterns of the predominant strains isolated from two outbreaks were identical; (2) they were identical to the PFGE patterns of the strains isolated from the green turtle and rana catesbiana which were bought from the same wholesale store.

CONCLUSIONGreen turtle and rana catesbiana that were contaminated by toxigenic O139 V. cholerae strains seemed to be the source of infection causing the O139 V. cholerae outbreaks in Jiangxi province. Rapid laboratory surveillance and epidemiologic investigation were important in identifying the source of infection during the outbreaks of V. cholera.

Objective: To explore the safety and effectiveness of a novel percutaneous self-expanding forceful reduction screw system in the treatment of thoracolumbar fracture with severe vertebral height loss. Methods: Thirty-eight patients of thoracolumbar fracture with more than 50%vertebral height loss were treated with the novel percutaneous self-expanding forceful reduction screw between March 2014 and June 2015. The screw system is a single plane screw with a reduction angle of 0,3,6,9 degrees. During the operation, the fracture vertebral body was automatically restored during the locking process of the top cap. All the patients were single vertebral fractures. Percutaneous screw fixation and reduction was used in the operation. Two groups of screws were used to fix the two adjacent vertebrae of the injured vertebra and to restore the injured vertebral body, without fusion treatment. The vertebral body index (VBI), height of the anterior margin of fractured vertebra (HAMFV), vertebral body angle (VBA), bisegmental Cobb angle (BCA), visual analog scale (VAS) and Oswestry disability index (ODI) of the patients before and after operation, 6 months after operation, and at the end of the follow-up were compared. The scoring results were compared using a t test. Results: The operation was completed successfully in 38 cases. A total of 152 screws were placed. The accuracy rate of CT evaluation was 98.7%. The average operation time was 90.7±21.9 min, and the average intraoperative bleeding amount was 89.2±31.9 ml. The patients' preoperative VBI, HAMFV, VBA, BCA, VAS and ODI scores were 0.38±0.07, 0.38±0.06, 25.45°±4.54°, 18.66°±8.57°, 7.76±1.02, and 44.58%±2.33%, respectively. The postoperative measurements were 0.93±0.03, 0.95±0.02, 3.71°± 1.35°, 5.84°±6.80 °, 4.29±1.16 and 24.37%±1.88%. At the last follow-up, the measurements were 0.92±0.03, 0.94±0.02, 3.89° ±1.31°,6.05°±7.00°, 1.71±0.65 and 5.95%±2.67%. There was significant difference between the preoperative and postoperative data, as well as the preoperative and the last follow-up data (P<0.05). Conclusion In the treatment of thoracolumbar fractures with severe loss of vertebral height, the novel percutaneous self-expanding forceful reduction screw system has achieved satisfactory vertebral height restoration and kyphosis correction.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

BACKGROUND: Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patient-assessed) and proportions of treatment cost to household income. METHODS: This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients' treatment satisfaction. RESULTS: When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 13.183, P = 0.004). For biological disease-modifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups (F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 8.794, P = 0.032). CONCLUSION Higher disease severity and higher financial burden were associated with lower patient satisfaction.
