Objective:To examine the characteristics of oculomotor inhibition about children with attention deficit hyperactivity disorder(ADHD).Methods:Twenty-one children with ADHD according to the Diagnostic and Statistical Manual of Mental Disorder,4th edition(DSM-IV) and 21 matched controls were administered with fixation,prosaccade and antisaccade tasks.Results:(1) In the fixation task,the children with ADHD demonstrated significantly more intrusive saccade errors than the controls in either condition with distractors or without distractors[no distractors:(12.67±12.28) vs.(6.38±6.95),P=0.040;distractors:(16.91±10.00) vs.(11.29±5.99),P=0.030].(2) In the prosaccade task,there were no significant differences found between groups in saccadic parameters,in either gap condition or overlap condition.(3) In antisaccade task,the direction error rates of the ADHD group in either gap condition or overlap condition,were both higher than that of the control group[gap:(68.14±17.85) % vs.(54.10±20.22) %,P=0.020;overlap:(62.49±17.54) % vs.(49.27±17.21) %,P=0.020].Conclusion: It suggests that there is an abnormality of the oculomotor inhibition,which may be caused by abnormal structure and/or function of fronto-striatal in ADHD children.

Objective To study the outcomes and problems of comprehensive medical pricing reform in Jiangsu.Methods The business operations,drug proportion and patient′s expenses of 28 pilot hospitals in 1 5 counties of the province before and after the reform were compared,to learn the impacts of the pricing reform on both hospitals and patients.Results Medical revenue and medical service quantity of these hospitals during this period(January to June)of 2012—2014 maintain a fast growth,with lower drug proportions,and patients′expenditure unchanged.Compared with data of the same period in 2012, the total revenue growth rates of the hospitals in 2013 and 2014 were 13.4% and 1 1.1% respectively;and their drug proportions were 44.9% and 42.3%;and the expenditure growth rates for outpatient/emergency service were 5.9% and 3.1% respectively.Conclusions The reform has achieved an initial success.However the pricing system,needs to be further rationalized to build a better price formation mechanism,in line with relevant reforms.

Objective To investigate the clinical features,diagnosis and treatment of pure redcell aplasia cased by human parvovirus B19 infection after renal transplantation.Method The clinical data including clinical symptoms and physical signs,laboratory and pathological examinations and outcomes of treatment in 8 cases at our hospital from Aug.2011 to Mar.2012 were analyzed retrospective,and relative literatures were reviewd.Result Pure red-cell aplasia occurred in all 8 cases 1 to 3 months after kidney transplantation,and one case had recurremt pure red-cell aplasia.The manifestations including recurrent reduction of hemoglobin,and pure red-cell aplasia was definitely diagnosed by bone marrow morphology,pathology,and polymerase chain reaction assay PVB19 DNA.Treatment of intravenous immunoglobulin and conversion of tacrolimus into ciclosporin was effective.Conclusion PVB19 is a rare but clinically significant infection that manifests as pure red cell aplasia during the early post-transplantation.Treatment of intravenous immunoglobulin and conversion of tacrolimus into ciclosporin in most cases was effective.

Purpose To investigate the relationship between Epstein-Barr virus (EBV) and lymphoepithelioma-like carcinoma (LELC) of the parotid gland and detect the gene expression products of EBV harbouring in LELC cells. Methods Thirty-two parotid LELCs were collected from the Departments of Pathology, Sun Yat-sen University of Medical Sciences, Guangzhou, China during the period of January 1986 and December 1995. All the 32 formalin-fixed paraffin-embedded blocks had been consecutively re-sectioned again. Immunohistochemical and in situ nucleic acid hybridization methods for detection of EBV gene encoded products were performed. Results (1) 32 LELCs were found out of 125 parotid gland carcinomas, the frequency was 25.6% (32/125). (2) All of the 32 specimens contained a variable number of EBNA-1 and EBERs positive neoplastic cells. (3) Twenty-seven out of 32 specimens (27/32, 84.4%) had a portion of carcinoma cells expressing LMP-1. (4) No ZEBRA positive cell could be found. (5) EA-D, VCA and MA positivity rates for these 32 parotid LELCs reached to 71.9%(23/32), 68.8%(22/32), and 12.5%(4/32), respectively. Conclusions (1) The parotid gland LELC is frequently to be seen in Guangzhou locale of China, where is a high-incidence area of nasopharyngeal carcinoma (NPC). The parotid gland LELC and NPC are co-prevalent in Guangzhou locale. (2) This disease is also consistently associated with EBV infection. (3) The EBV infection of the parotid gland LELCs is essentially the type of latency Ⅱ, expressing EBNA-1, EBERs and LMP-1. (4) The latent infected EBV harbouring in LELC cells could in part be switched over to lytic cycle, producing EA-D, VCA or/and MA.

Objective To compare the long-term effectiveness of anti-interleukin-2 receptor antibodies vs.rabbit antithymocyte globulin as induction therapy in kidney transplantation.Methods Between 2006 and 2010,371 recipients of kidney transplants were treated with calcineurin inhibitors (CNI),mycophenolate mofetil and prednisone.261 patients of them received induction therapy with anti-interleukin-2 receptor antibodies (IL2Ra group),and 88 patients received rabbit antithymocyte globulin (rATG group).All the patients received ganciclovir against cytomegalovirus and SMZ against pneumocystis carinii.The data of delayed graft function (DGF),the rate of acute rejectin (AR) and infection in the first year and patient/allograft long survival rate in two groups were retrospectively analyzed during a follow-up period of 1 to 5 years postoperatively.Results There was no significant difference in the sex,age and causes of end-stage renal disease between the two groups.The rATG group had more kidney transplants from deceased donors (P＜0.01 ) and the cold ischemia time was longer than that of the IL2Ra group (P＜0.01 ).The IL2Ra group and the rATG group had similar incidence of DGF (3.1％ vs.1.8％,P＞0.05).One year after operation,the incidence of AR in IL2Ra group and rATG group was 10.7％ and 2.7％ respectively (P＜0.05),and the incidence of infection in IL2Ra group and rATG group was 14.9％ and 21.8％ respectively (P＞0.05).One-,two- and three-year patient survival rate in IL2Ra group was 98.9％,98.9％ and 98.5％ respectively,and that in rATG group was all 98.2％ (P＞0.05).The one-,two- and three-year allograft survival rate in IL2Ra group was 98.5％,98.1％ and 97.7％ respectively,and that in rATG group was all 97.3％ (P＞0.05).Conclusion rATG is more effective than IL2Ra preventing from acute rejection and does not increase the risk of infection for induction in kidney transplant recipients.

Objective To discuss the pathogenesis of the statin-induced rhabdomyolysis in renal transplant recipients.Methods We presented two renal transplant recipients who developed rhabdomyolysis in 2012 in our hospital.The clinical presentation,laboratory results,diagnosis and treatment of the two patients were analyzed retrospectively.The basic immunosuppressive agent of two patients was cyclosporine A.The recipients developed rhabdomyolysis following simvastatin lipidlowering therapy,and one patient suffered acute renal failure simultaneously.Acute tubular injury was confirmed by renal biopsy.Finally,the symptoms of the two patients were relieved completely,creatine kinase (CK) returned to normal after the satins discontinued and saline,sodium bicarbonate and diuretics were given.The renal failure patient underwent plasma exchange and CRRT,and the renal function returned to normal.Results The level of cyclosporine A should be monitored when the renal transplant patient was given statins,especially whose basic immunosuppressive agent was cyclosporine A.At the same time we should pay more attention to the symptoms of the myotoxic side effects and avoid using the drug which was also metabolized by CYP3A4.Conclusion Physicians should be aware of the potential risks of combined therapy of statins which are metabolized by P450CYP3A4 and cyclosporine A in transplant patients.If using it is advisable to begin with small dosage and monitor the CK level.

OBJECTIVE:To prepare Dexzopiclone orally disintegrating tablets (DODT),and to optimize its formulation.METHODS:Direct powder compression method was used to prepare DODT.Using repose angle of material,disintegration time and taste evaluation as indexes,single factor test was used to screen the types or amount of bulking agent,disintegrating agent,glidant and flavoring agent;using disintegration time as index,orthogonal experiment was applied to optimize the proportion of bulking agent,the amount of disintegrating agent,glidant and flavoring agent.Then the hardness and main component contents of DODT prepared by optimal formulation were determined.RESULTS:The optimal formulation was as follows as the ratio of mannitol-MCC 1 ∶ 4,the amount of disintegrating agent PVPP was 15％,the amount of glidant magnesium stearate was 1.0％,the amount of flavoring agent stevia was 3.0％.Three batches of prepared DODT were smooth in surface and good in taste;their disintegration time were(26.7 ± 1.2),(26.7 ± 0.6),(27.6 ± 0.9)s,hardness were (3.59 ± 0.19),(3.49 ± 0.18),(3.27 ± 0.16) kg,and contents were (99.47 ± 0.15) ％,(99.53 ± 0.05)％,(99.46 ± 0.20) ％,respectively (all RSDs≤0.87％,n=3).CONCLUSIONS:Prepared DODT are all in line with the quality requirements of orally disintegrating tablets.

Objective:To evaluate the effect of airway driving pressure (ΔP) guided sedation strategy on the prognosis of patients with mechanical ventilation.Methods:Patients who needed invasive mechanical ventilation and admitted to the department of intensive care unit (ICU) of Jiangxi Provincial People's Hospital from January 2017 to December 2018 were enrolled. The patients were divided into study group and control group according to the random number table. After informed consent of patients or their families, both groups received routine treatment in ICU. The control group was treated with light sedation strategy, the Richmond agitation sedation score (RASS) was performed every 4 hours, and the target was RASS > -3. ΔP in the study group was measured once a day, and the sedative target of patients with low driving pressure (ΔP ≤ 14 cmH 2O, 1 cmH 2O = 0.098 kPa) was RASS > -3, while the patients with high driving pressure (ΔP > 14 cmH 2O) was RASS ≤ -3. The evaluation was conducted at 28 days after admission to ICU, and the patients were followed up to 60 days. The main outcome was days without mechanical ventilation in 28 days. The secondary outcomes were the rate of extubation, discharge outcome, incidence of ventilator associated pneumonia (VAP) and delirium, and 60-day survival rate. Results:A total of 60 patients with respiratory failure due to various reasons were recruited, 30 in each group. There was no significant difference in gender, age, primary disease, severity of disease or ΔP between the two groups. The days without mechanical ventilation within 28 days in the study group were significantly more than that in the control group [days: 20 (0, 23) vs. 12 (0, 16), P = 0.018], and the incidences of VAP (3.3% vs. 16.7%, P = 0.045) and delirium (0% vs. 10.0%, P = 0.038) were significantly lower than that in the control group. There were no significant differences in the rate of extubation (73.3% vs. 66.7%, P = 0.273), discharge outcome [improvement (cases): 24 vs. 21, unhealed (cases): 2 vs. 5, deaths (cases): 4 vs. 4, P = 0.506] and 60-day survival rate (83.3% vs. 76.7%, P = 0.519) between the study group and control group. Conclusion:Compared with light sedation strategy, ΔP directed sedation strategy can effectively shorten the duration of mechanical ventilation and reduce the incidence of VAP and delirium in the ICU patients.

BACKGROUND:Physiotherapy is very important for the recovery after anterior cruciate ligament reconstruction.In recent years,many doctors are optimizing the physical rehabilitation program after anterior cruciate ligament reconstruction.However,there is still a lack of efficient rehabilitation training after anterior cruciate ligament reconstruction. OBJECTIVE:To investigate the effect of vibration therapy combined with suspension training on movement and knee joint function after anterior cruciate ligament reconstruction. METHODS:A total of 80 patients undergoing first unilateral anterior cruciate ligament reconstruction at the Affiliated Sport Hospital,Shanghai University of Sport were randomly divided into vibration therapy group(n=40)and vibration therapy+suspension training group(n=40).In the vibration therapy group,vibration therapy(10 minutes each,once a day,6 times per week)was performed at the 13th week after anterior cruciate ligament reconstruction.Patients in the vibration therapy+suspension training group were treated with vibration therapy(10 minutes each,once a day,6 times per week)and suspension training(twice a week)at the 13th week after anterior cruciate ligament reconstruction.Training in each group was performed for 8 weeks.Knee joint function was evaluated by knee joint Lysholm score before and 8 weeks after training.The symmetry index was evaluated by the isokinetic muscle strength evaluation training system.The balance test system was used to evaluate the average trace error difference of the bilateral multi-axes. RESULTS AND CONCLUSION:Compared with those before training,the knee Lysholm score and the knee extension and flexion symmetry indexes increased(P<0.05),and the average trace error difference decreased after training(P<0.05).Compared with the vibration therapy group,the knee Lysholm score in the vibration therapy+suspension training group increased(P<0.05),the knee extension and knee flexion symmetry index increased(P<0.05),and the average trace error difference decreased(P<0.05).To conclude,compared with vibration therapy training alone,vibration therapy combined with suspension training can significantly improve knee joint function,increase muscle strength and symmetry,and improve balance stability in patients undergoing anterior cruciate ligament reconstruction.

OBJECTIVETo evaluate the risk of nasopharyngeal carcinoma (NPC) through EB virus antibody profile by enzyme linked immunosorbent assay (ELISA).

METHODSEBNA 1/IgA, EBNA 1/IgG and zta/IgG by ELISA and VCA/IgA by immmunoenzymatic method were detected in 121 NPC patients and 332 healthy subjects (HS) in the Pearl river estuary.

RESULTSThe sensitivity rates were 85%, 83% and 79% for EBNA 1/IgA, EBNA 1/IgG and zta/IgG, all three of which if combined was the highest 92%. The specificity rates were 86%, 86% and 80% for EBNA 1/IgA, EBNA 1/IgG and zta/IgG, all three of which if combined was also the highest 93%. According to the level of odds ratio, nasopharyngeal carcinoma risk could be divided into 3 groups: low, moderate and high-risk groups. 93% of HS had low risk of NPC with the odds ratio 0.0 to 0.3. 0.4% of HS had high risk of NPC with the odds ratio of 137.9%.

CONCLUSIONELISA is more objective than the traditional immunoenzymatic method in the detection and diagnosis of NPC. The combination of EBNA 1/IgA, EBNA 1/IgG and zta/IgG is able to evaluate the risk of NPC.
