OBJECTIVE To explore the role of clinical pharmacists participating in the standardized perioperative nutritional management process for pancreaticoduodenectomy （PD） on improving postoperative recovery in patients. METHODS The clinical data of 100 patients undergoing PD in the Department of Biliary and Pancreatic Surgery， Drum Tower Hospital Affiliated to Nanjing University School of Medicine from November 2019 to February 2021 were analyzed retrospectively. According to the different perioperative nutrition management plans， they were divided into clinical pharmacist intervention group （n＝51， clinical pharmacists intervened according to the standardized nutrition management process） and control group （n＝49， clinical pharmacists only performed preoperative nutrition evaluation， and clinical physicians took nutrition support according to the patient’s condition）. The differences in postoperative recovery index， economic evaluation index， hospitalization length， postoperative complications， and postoperative enteral nutrition support route were compared between 2 groups. RESULTS The time of postoperative diet， the first postoperative ventilation， the first postoperative defecation， and postoperative drainage time of abdominal drain were significantly earlier in the clinical pharmacist intervention group than in the control group （P＜0.05）； the hospitalization cost， medication cost， nutritional support cost， parenteral nutrition cost， albumin preparation cost， and the length of postoperative hospitalization were significantly lower/shorter in the clinical pharmacist intervention group than in the control group （P＜0.05）； there was no statistically significant difference in the incidence of postoperative complications between the two groups （P＞0.05）； there was statistically significant difference in the perioperative enteral nutrition support pathways between two groups （P＜0.05）. CONCLUSIONS Clinical pharmacists’ participation in perioperative nutritional management for PD can significantly reduce hospitalization costs and nutritional support costs， improve patients’ perioperative nutritional status， and shorten hospital stays. wanglina668@163.com

OBJECTIVE: To explore the clinical and molecular characteristics of a child with Congenital disorders of glycosylation (CDG). METHODS: A 4-month-old boy who had presented at the Children's Hospital Affiliated to Zhejiang University Medical School on December 31, 2019 due to feeding difficulties after birth was selected as the study subject. High-throughput sequencing was carried out for the patient, and real-time qPCR was used for validating the suspected deletion fragments and the carrier status of other members of his family. RESULTS: High-throughput sequencing revealed that the child had lost the capture signal for chrX: 153 045 645-153 095 809 (approximately 50 kb), which has involved 4 OMIM genes including SRPK3, IDH3G, SSR4 and PDZD4. qPCR verified that the copy number in this region was zero, while that of his elder brother and parents was all normal. CONCLUSION The deletion of the fragment containing the SSR4 gene in the Xq28 region probably underlay the SSR4-CDG in this child.

Objective:To summarize the clinical characteristics of central nerve system (CNS) infection and grasp the necessity and possibility of early diagnosis and precise intervention of CNS infection after renal transplantation.Methods:This retrospective study enrolled consecutive recipients of renal transplantation with CNS infection after transplant between January 2000 and December 2020. Correlative factors for CNS infection after renal transplant were determined by comparing the clinical data between recipients with and without CNS infection. After screening 3, 199 consecutive renal transplant recipients, 12 patients with CNS infection post-transplant were identified and recruited. The median age-of-onset was 48.5 (23-65) years. And the median time to disease onset after transplant was 50.5(1-204) months. The most common symptoms of CNS infection after renal transplant included fever (75.00%), consciousness disorder (58.33%), headache (58.33%) and neck rigidity (41.67%).Results:Hepatitis B virus carrier and pulmonary infection were correlated with CNS infection after transplantation ( P<0.05). Nine patients failed to identify the pathogen and only received empirical anti-infective regimen. The outcomes were curing ( n=3) and death ( n=6). Metagenomic sequencing was performed for identifying the pathogen in three recipients and actively adjusting the anti-infective regimen. As a result, 2 were cured and 1 died. The overall mortality was 58.33%. The median time to death or curing from disease onset were 20(2-19) and 25(16-35) days respectively in surviving and non-surviving recipients. Conclusions:The progress of CNS infection after transplantation is rapid with a high mortality. HBV carrier and pulmonary infection are possible risk factors of CNS infection after renal transplantation. Early pathogenic identification and precise etiological intervention are vital for better clinical outcomes.

OBJECTIVE: To analyze the characteristics of BK polymavirus (BKV) infection and the optimal time window for intervention in kidney transplant recipients (KTRs). METHODS: We retrospectively analyzed the clinical data and treatment regimens in 226 KTRs in our center between January, 2013 and January, 2018. Among the recipients, 157 had a urine BKV load ≥1.0×10 copy/mL after transplantation, and 69 had a urine BKV load below 1.0×10 copy/mL (control group). RESULTS: Among the 157 KTRs, 60 (38.2%) recipients were positive for urine BKV, 66 (42.0%) had BKV viruria, and 31(19.7%) had BKV viremia. The incidence of positive urine occult blood was significantly higher in BKV-positive recipients than in the control group ( < 0.05). The change of urine BKV load was linearly related to that of Tacrolimus trough blood level (=0.351, < 0.05). In urine BKV positive group, the average estimated glomerular filtration rate (eGFR) was below the baseline level (60 mL·min·1.73 m) upon diagnosis of BKV infection reactivation, and recovered the normal level after intervention. In patients with BKV viruria and viremia, the average eGFR failed to return to the baseline level in spite of improvement of the renal function after intervention. CONCLUSIONS Positive urine occult blood after transplantation may be associated with BKV infection reactivation in some of the KTRs. BKV infection is sensitive to changes of plasma concentration of immunosuppressive agents. Early intervention of BKV replication in KTRs with appropriate dose reduction for immunosuppression can help to control virus replication and stabilize the allograft function.

Objective To evaluate the clinical value of the upper extremital artery supply and vein running back in the patients after peripheral vascular surgery by Na99mTcO4 trace imaging(TTI).Methods SPECT static imaging was performed on 36 patients after peripheral vascular surgery in vein injecting Na99mTcO4 740 MBq 5min.The radioactivity uptake of operated limb(finger)/normal limb(finger) ratio(T/NT) was analyzed using region of interest analysis.0,Ⅰ,Ⅱand Ⅲ scales were classified according to their radionuclide distribution and T/NT,were divided into A,B,C and D group,respectively.Localy warming and anticontrctive therapy were only given in A and B group for 30min,routine therapy in C group,and raising operated limb (finger) and reductive pressure treatment in D group.Then,exploratory surgery was performed on 0 scales and Ⅲ scales of TTI again.Results A,B,C and D group were 11,7,13 and 5 patients,their T/NT was (0.142 ± 0.058),(0.384 ± 0.046),(0.794 ± 0.072) and (1.12 ±0.076),respectvely,and there were significant differences among the groups(t =2.33a,4.33b,6.90b,2.59a,5.73b,2.12a,aP ＜ 0.05,b P ＜ 0.O1) ;TTI again showed:there were 7 cases of 0 scales (arterial thrombosis was confirmed by exploratory surgery) and 4 cases of Ⅰ scales in A group,3 cases of Ⅰ scales and 4 cases of Ⅱ scales in B group,all 13 cases of Ⅱ scales in C group,4 cases of Ⅱ scales and 1 case of Ⅲ scales(vein thrombosis was confirmed by exploratory surgery) in D group.Conclusion TTI could play an important role in economical,simple and notraumatic diagnosing the extremital artery supply and vein running back in the patients after peripheral vascular surgery.

Objective To explore the effects of cyclosporin A (CsA) and tacrolimus (Tac) on biological behaviors of lung cancer A549 cells in nude mice.Methods Thirty-six models of transplanted tumor in Balb/c mice were established by using lung cancer A549 cells and divided into three groups:control group,without given any immunosuppressant; CsA group,intraperitoneally given CsA; Tac group,intraperitoneally given Tac.The transplanted tumor growth curve was drawn according to the transplanted tumor volume,and the influencing ratio was calculated according to the final tumor weight.The changes in cell migration ability were observed by using Transwell system.Terminal deoxynucleotidyl transferase mediated UTP nick end labeling (TUNEL) assay was used to examine the apoptosis index of the transplanted tumor.Quantitative RT-PCR was used to detect the expression levels of Bcl-2 mRNA and Bax mRNA.Results The growth of transplanted tumor in CsA and Tac groups was faster than in control group.Final tumor volume and final tumor weight in CsA and Tac groups were greater than those in control group.The influencing ratio in CsA and Tac groups was 19％ (P＜0.05) and 25％ (P＜0.05),respectively.The migration ability was greater in CsA and Tac groups than in control group (P＜0.01).The apoptosis index of the transplanted tumor in CsA and Tac groups was lower than in control group (P＜0.05).The expression level of Bcl-2 mRNA was higher in CsA and Tac groups than in control group (P＜0.05),and that of Bax mRNA was lower in CsA and Tac groups than in control group (P＜0.05).Conclusion Both CsA and Tac can promote the growth of transplanted tumor in nuce mice bearing 549 cells and enhance the invasion forces,which is probably related with the apoptosis induction of tumor cells.

Objective To evaluate the curative effects of conversion from mycophenolate mofetil (MMF) to enteric-coated mycophenolate sodium (EC-MPS) on MMF-related chronic diarrhea in the renal transplant (RT) recipients of long-term stage following transplantation.Methods Twenty-six RT recipients with persistent and severe diarrhea,diagnosed as MMF-related diarrhea after a systemic examining procedure including macroscopic and microscopic examinations of the upper and lower gastrointestinal tracks,serology of the blood for CMV and culture of stool for the bacteria.In all the 26 recipients,the dosage of MMF was reduced to 250 mg,twice every day for 2 weeks.Those without significant improvement at the end of this period were shifted to EC-MPS at a dose of 180 mg,twice every day for 2 weeks.The EC-MPS dose was increased to 360 mg,twice every day if the symptoms were improved significantly at the third week after conversion,or EC-MPS was withdrawn if the diarrhea still existed.The dosage of EC-MPS would be reduced to 180 mg,twice every day if the diarrhea recurred in the next 3 months. The clinical symptoms,biological parameters and renal function were observed for 3 months after the conversion.Results ( 1 ) All the 26 recipients were switched to EC-MPS because of the persistent existence of diarrhea after reduction of MMF.After conversion,the diarrhea disappeared completely in 19 out of the 26 recipients in 2 weeks and 2 patients also showed significantly improvement of diarrhea with the total efficiency being 80.8％ (21/26).In the rest 5 cases,EC-MPS was withdrawn at the second week; (2) The disturbance of internal environment was improved significantly following the EC-MPS conversion.Serum potassium,sodium and TCO2 were elevated to normal level.The benefit was predominantly observed in the recipients with moderate to severe proteinuria.The 24-h urinary protein secretion was significantly reduced from 0.76±0.48 to 0.46±0.53 (g/24 h) (P＜0.05) at the third month.Conclusion In RT recipients with MMF-related chronic diarrhea after long-term stage following renal transplantation,switching MMF to EC-MPS can significantly alleviate the diarrhea and rectify the imbalance of internal environment of the recipients.

Objective To explore the impact of induction therapy with anti-lymphocyte agents on long-term survival of kidney transplantation.Methods 271 recipients of first cadaveric kidney transplants were treated with tacrolimus,mycophenolate mofetil and prednisone.110 patients of them received induction therapy with anti-thymocyte globulin(ATG group),88 patients received Basiliximab(Bax group),and the remaining 73 patients did not receive induction therapy(control group).The data of AR,DGF,CMV infection,and 1- 3- 5-year patient/allograft survival rate in three groups were retrospectively during a follow-up period of 1 to 5 years postoperatively.Results Within 6 months after operation,the incidence of AR in control group,ATG group and Bax group was 17.8 %(13/73),9.1 %(10/110)and 10.2 %(9/88)respectively.The incidence of AR in ATG group and Bax group was significantly lower than in control group (P<0.05).There was no significant difference in incidence of DGF and CMV infection among three groups.The 1-,3- and 5-year allograft survival rate postoperation in ATG group and Bax group was 95.5 %,90.9 %,87.3 % and 93.2 %,87.5 %,83.8 % respectively,which was significantly higher than in control group(87.7 %,80.8 % and 75.3 %,P<0.05).Conclusion Induction therapy with anti-lymphocyte agents may reduce the early incidence of AR and prolong long-term allograft survival significantly.
