Objectives:To observe the role of nutritional support in patients after liver transplantation. Methods:Nutritional support was used in three patients after orthotopic liver transplantation(OLT).Total parenteral nutrition(TPN) was administered since the second day after the operation,the combination of enteral nutrition(EN) and parenteral nutrition(PN) was followed and then total enteral nutrition(TEN) was adopted.After that,oral intake of food was restored. Results:Postoperative patients were restored well. Conclusions:The supply of nutrition for patients after liver transplantation should be TPN→PN+EN→TEN,and then gradually increased.Once the gastroenteric functions of patients recover it is advisable to start EN as soon as possible.

From August 2011 to March 2012,5 241 type 2 diabetic patients with body mass index ≥ 24kg/m2 were enrolled from 60 hospitals in Guangdong Province.According to estimated glomerular filtration rate (eGFR),a total of 2 631 subjects with norml urine microalbumin level (＜30 ng/L) were divided into normal eGRF group and decreased eGRF group.Binary logistic regression was used to analyze the associations between eGFR and its related risk factors.The results showed that age,blood uric acid,blood urea nitrogen,history of hypertension and coronary heart disease,family history of diabetes,and hyperuricemia were positively related to lowering of eGFR (P＜ 0.05 or P＜0.01).HbA1C＜7％,regular glucose monitoring,and regular physical activity were negatively related to eGFR decrease (all P＜ 0.01).These results suggest that urine microalbumin and eGFR should be applied to overweight or obese patients with type 2 diabetes in order to screen diabetic nephropathy.Furthermore,intensive control of blood glucose,uric acid,and blood pressure is beneficial to lowering the risk of diabetic nephropathy.

OBJECTIVETo evaluate effectiveness therapeutic regimens for obstructive sleep apnea hypopnea syndrome (OSAHS) children at an acceptable cost.

METHODThis study was performed at Yuying Children's Hospital of Wenzhou Medical University from Mar. 2008 to Dec. 2010. Prospective random number table method was used for the analysis; 60 children with mild OSAHS were divided into Mild OSAHS Montelukast Treatment (MM) group and Mild OSAHS Adenotonsillectomy Treatment (MAT) group. 32 children in MM group were treated with leukotriene receptor antagonists (LTRAs), while 28 children in MAT group were treated with adenotonsillectomy. Also, 58 children with moderate and severe OSAHS were divided into severe OSAHS Montelukast Treatment (SM) group and severe OSAHS Adenotonsillectomy Treatmen (SAT) group. Twenty-two children in SM group were treated with LTRAs, while 36 children in SAT group were treated with adenotonsillectomy. All selected children were evaluated by polysomnography (PSG) and Obstructive Sleep Apnea-18 (OSA-18) items before and after a six-month treatment. Both records were taken and analyzed, surgical complications and the reason for non-remission after operation were also analyzed. Two therapies were compared based on economic consideration and therapeutic effect. Result (1) PSG: A significant change of a significant change of Apnea Hypopnea Index (AHI) was observed in MM group after the treatment (before receiving the treatment 4.56 ± 1. 26, and after receiving the treatment 3. 48 ± 1. 52, t =3. 50, P <0. 05). But for oxygen desaturation Index (ODI) (MM group 2. 18 ± 2. 19, and MAT group 1. 80 ± 2. 34) and Lowest Oxygen satuation (LSaO2) (MM group 91. 66 ± 2. 34, and MAT group 92. 79 ± 2. 18), there was no significant difference in MM group and MAT group after the treatment (ODI, t =0. 65, and LSaO2 t = - 1. 93, P >0. 05). (2) OSA-18 scores: Significant differences were found in sleeping disorder (before 14. 81 ± 6. 28, and after 10. 56 ± 3. 57), the degree of familial stress (before 13. 56 ± 3. 54, and after 8. 97 ± 2. 96), and OSA-18 total scores (before 52. 66 ± 1. 11, and after 42. 56 6. 48) in MM group after the treatment (sleeping disorder Z - 3. 14, the degree of familial stress Z = -4. 50, and OSA-18 total scores Z= -4. 01, P <0. 05). (3) In addition to the cost of drugs, groups with surgical treatment had a larger economic burden than those with LTRAs treatment. (4) Treatment was totally effective for 28 children (88%) in MM group, and 28 children (100%) in MAT group. Meanwhile, treatment also achieved an obvious effect on 2 children (9%) in SM group, and in 35 children (97%) in SAT group. In MAT group, 3 children improved (11%). And in SAT group, 7 children improved (19%), but treatment was found to be ineffective in 1 case (3%). Among those effective and ineffective cases in groups with surgical treatment, there were 9 children with nasal diseases.

CONCLUSION(1) Surgical treatment is recommended as the first choice for children with moderate and severe OSAHS. And for those who also suffer from nasal diseases, treatment combining drugs with surgery is necessary. (2) LTRAs therapy has a good effect for mild OSAHS. Surgery is also recommended when drugs could not achieve any obvious improvement in clinical symptoms of children with mild OSAHS.

[Objective]This study was aimed to evaluate treatment outcomes and toxicity of continuous-infusion EPOCH regimen for NK/T-cell lymphoma(NK/TCL).[Methods]From June 2003 to June 2008,34 patients including 30 nasal NK/TCL (88.2%)and 4 nasal type NK/TCL(11.8%)received doxorubicin,vincfistine,etoposide over 96 hours infusion with bolus eyelophosphamide and oral predinisone(EPOCH)chemotherapy as first-line treatment.Median cycles of EPOCH administered were 2.5(1-6 cycles).Additional involved field radiation therapy(IFRT)was administered to patients with localized nasal focus after chemotherapy.[Results]Among 34 patients,33 were eligible for response evaluation.The response rate(RR)was 60.6% (20/33)with complete remission(CR)rate of 45.5%(15/33).The RR of patients with nasal NK/TCL was 66.7%(20/30)with CR rate of 50%(15/30).Only one of the 3 nasal type NK/TCL patients achieved stable disease(SD),the other 2 had progressive disease(PD)during chemotherapy.After a median follow-up of 22(2-68)months,the estimated 3-year overall survival rate(OS)was 52.2%.For patients with nasal NK/TCL,the estimated median survival time was not reached,the 3-year OS was 59.4%.For patients with nasal type NK/TCL,the estimated median survival time was only 7 months.The CR rate was 75.0% for localized nasal NK/TCL who received initial EPOCH chemotherapy followed IFRT with the 3-year OS of 75.0%.Major adverse effect was myelosuppression.The incidence of grade Ⅲ～Ⅳ neutropenia was 30.9%.No treatment-related mortality occurred.[Conclusions]EPOCH regiment was effective and well tolerant for nasal NK/TCL.Combined EPOCH chemotherapy followed by IFRT produced promising outcome for patients with localized disease.However,patients with nasal type NK/TCL responded poorly and more efficacious treatment strategies are urgently needed.

[Objective]To evaluate the clinical efficacy and side effects of DHAOx±R regimen in the patients with relapsed and refractory non-Hodgkin's lymphoma(NHL).[Methods]Twenty patients with relapsed or refractory NHL were enrolled into this study in Cancer Center of Sun Yat-sen University.These patients were treated with DHAOx±R regimen(Dexamethasone 20 mg/day intravenous(Ⅳ)on day 1 to day 4,cytarabine 2 000 mg/m~2 3 h Ⅳ,every 12 hours on day 2;oxaliplatin 130 mg/m~2 2 h Ⅳ on day 1;with or without rituximab 375 ms/m~2 on day 0).Six patients were followed by high dose chemotherapy with autologous peripheral blood stem cell transplantation.Response to treatment wag assessed according to The International Working Group Criteria,including CR,PR,SD and PD.Side effects were graded according to WHO criteria,including 0-Ⅳ grades.[Results]Twenty patients received 47 cycles chemotherapy,13 patients(65%)received DHAOx chemotherapy and 7(35%)received DHAOx+R.The response rate(RR)for the whole group was 55%(11/20)with comeplete response(CR)rate 35%(7/20).The response can also be obtained in the patients who were already treated by platinum-based regimen before.The major toxicity Wag myelosuppression.The incidence of grade Ⅲ～Ⅳ neutropenia Wag 35%(16/47),and febrile neutropenia was 17%(8/47).The incidence of grade Ⅲ～Ⅳ thrombocytopenia was 20%(9/47).Eight cycles(17%)occurred mild neumtoxicity.With median follow-up of 12 months,1 and 2-year overall survival rate were 70.6%.[Conclusion]DHAOx was an effective regimen for recurrent and relapsed NHL patients with mild side effects and further investigation is needed.

Objective To evaluate the efficacy of oxycodone for patient-controlled intravenous analgesia (PCIA) after hip arthroplasty in elderly patients.Methods Sixty patients of both sexes,aged 65-85yr,weighing 42-89 kg,of American Society of Anesthesiologists physical status Ⅰ or]Ⅱ,scheduled for elective unilateral hip arthroplasty under general anesthesia,were divided into 2 groups (n =30 each) using a random number table:morphine group (group M) and oxycodone group (group O).Parecoxib sodium 40 mg was injected intravenously at 30 min before induction of anesthesia,followed by induction and maintenance of anesthesia.PCIA pump was connected at the beginning of skin closure.PCIA solution contained morphine 0.6 mg/kg and tropisetron 10 mg diluted to 100 ml in normal saline in group M and oxycodone 0.6 mg/kg and tropisetron 10 mg diluted to 100 ml in normal saline in group O.The PCA pump was set up with a background infusion at 2 ml/h,a 0.5 ml bolus dose and a 15 min lockout interval in both groups.Visual analogue scale score was maintained ≤ 3,and postoperative analgesia lasted until 48 h after operation.When analogue scale score ≥ 4,pethidine 50 mg/kg was injected muscularly as rescue analgesic.The requirement for rescue analgesic and occurrence of adverse effects were recorded.Results Ten percent patients required rescue analgesics in group M,and no patients required rescue analgesics in group O.Compared with group M,the requirement for rescue analgesics and incidence of nausea,vomiting and pruritus were significantly decreased in group O (P＜0.05).Conclusion Oxycodone provides reliable efficacy for PCIA after hip arthroplasty in elderly patients with fewer adverse effects,indicating that oxycodone produces good analgesic efficacy for severe somatalgia.

Objective To understand the effectiveness of peroral endoscopic myotomy(POEM)for achalasia and secondary severe malnutrition in children and the effectiveness of nutrition support before and after POEM.Method Treatment of POEM,nutrition support(tube feeding by percutaneous endoscopic gastrostomy three months before operation)in one case were recorded and analyzed.Results POEM was successful without any complication such as perforation,bleeding,and pneumoderm.The child suffered from fever after surgery,which was dissolved after symptomatic treatment three days later.Chest pain was relieved after changing position.The diet was changed from liquid to semifluid,and then to normal diet.The child did not have dysphagia.During the 6-month follow-up,the patient had normal diets by oral route.The weight was 32 kg before achalasia and decreased to 18 kg after 9 months(at admission);it then increased to 29 kg after short-time(12 days)parenteral nutrition and long-time(3 months)enteral nutrition by percutaneous endoscopic gastrostomy,and then the patient received POEM.His weight was 30,31,31,29,and 31 kg 1,4,6,9,and 13 months,respectively,after POEM.Conclusion POEM can effectively cure achalasia in pediatric patients and improve the quality of life.Rational enteral nutrition can improve nutrition status and facilitate a successful POEM.

Objective To investigate the application value of Photoshop in grading invasive risk of gastric stromal tumors (GSTs). Methods EUS image of 97 cases of GSTs confirmed by pathological and immunohistochemical examination were collected. GSTs were divided into four groups (very low risk, low risk, intermediate risk, high risk) by tumor size, mitotic count and rupture of tumor. Mean gray value (intensity of echo) and gray value standard deviation (uniformity of echo) of EUS images of the lesions were determined by Photoshop and then the differences of each group were found by statistical analysis. Results It is difficult to differentiate EUS images of GSTs from each group by visual observation. The mean gray value of EUS image of very low risk group,low risk group, intermediate risk group and high risk group of GSTs respectively were (56.54 ± 6.10), (59.20 ± 7.51), (77.77 ± 10.90) and (83.43 ± 12.47). There was no significant difference between very low risk group and low risk group (P > 0.05). There was no significant difference between intermediate risk group and high risk group (P > 0.05). In addition, the others all had significantly different from that of each group (P < 0.05). The mean gray value standard deviation of EUS image of very low risk group, low risk group, intermediate risk group and high risk group of GSTs respectively were (8.46 ± 2.59), (12.57 ± 5.89), (12.84 ± 4.15) and (16.69 ± 4.69). There was no significant difference between low risk group and intermediate risk group (P > 0.05). In addition, the others all had significantly different from that of each group (P < 0.05). Conclusions The higher risk of GSTs, the higher of echo intensity and the worse of echo uniformity under EUS. Photoshop combined with EUS is helpful for differentiating different risk of GSTs by analyzing mean gray value and gray value standard deviation of the lesions.

Objective To investigate the protective effect of protocatechuic acid(PCA)on the PC12 cell model of Alzheimer’s disease(AD)and to explore its mechanism . Methods Amyloid beta peptide 1-42(Aβ1-42)fiber polymers were identified by immunofluorescence. After PC12 cells were stimulated with the Aβ1-42 fiber polymers, the cellular morphology was observed at different time points of hour 0, 3, 6, 9, 12, 24 , and the cellular viability was tested by methyl thiazolyl tetrazolium(MTT)assay to monitor the modeling condition. The effect of PCA on PC12 cells was detected after PC12 cells were pretreated with the different contentions of PCA. Autophagy-related marker Beclin1 protein level was detected by Western blotting method to investigate the protective mechanism of PCA. Results Aggregated white Aβ1-42 mass was stable at hour 12 and 24, and showed no significant difference between the two time points, the cell damage rate being 40%. Therefore, we defined culturing time being 12 and 24 hours as the modeling condition of AD model. The cell viability was increased with 200-800 μmol/L of PCA after culturing for 24 hours(P<0.01) , and the Western blotting results showed that the Beclin1 protein expression was up-regulated by PCA. Conclusion PCA prevents PC12 cells from Aβ1-42-induced toxicity, the mechanism being related with the increase of cellular autophagy.

Objective To evaluate the efficacy and toxicity of SMILE regimen for NK/T-cell lymphoma. Methods From November 2006 to February 2008, 5 patients with relapsed and 5 with first treatment NK/T-cell lymphoma were involved in this study. These patients were treated with SMILE regimen including methotrexate, isofosfamide, L-asparaginase and etoposide.1 patient were treated with autolognus hematopoietic stem cell transplantation (AHSCT), and 2 patients received local regional radiation following SMILE. Results Among 10 patients, 8 were eligible to response evaluation. The overall response rate for whole group was 50 %(4/8) without complete remission. The overall response rate for both previously untreated and relapsed patients were 50 %(2/4). Major toxicity were bone marrow supression and transient transaminase elevation, the incidence of grade Ⅲ -Ⅳ neutroponia was 65 %, and febrile neutropenia was 25 %, Grade Ⅲ transaminase elevation was 10 %. Other toxicities were mild, no treatment-related mortality occurred. 26.1% cycles discontinued due to severe side effect. Conclusion SMILE may be an effective regimen for relapsed or refractory NK/T-cell lymphoma while significant toxicities were observed. Further investigation is requried before SMILE become a standard combination for relapsed or refractory NK/T-cell lymphoma.
